Steam Generator for Hair-Straightening Combs

The present disclosure relates to the technical field of steam generators, and in particular to a steam generator for hair-straightening combs.

The proliferation of technology has facilitated the integration of hair-straightening combs into consumer lifestyles. A hair-straightening comb is an electronic device that operates at elevated temperatures to soften and straighten hair. The device utilizes electric heating to warm either the comb teeth or the base plate, allowing the high temperature to heat and soften the hair as it is combed, thereby achieving a straightening effect. However, exposure to high temperatures can lead to moisture loss in the hair, resulting in increased dryness and potential damage. Moreover, conventional hair straightening tools typically employ a clamp design, featuring electric heating plates positioned on the inner sides of the clamps. The hair is straightened by the application of heat from these two heating plates. These tools can only straighten the hair and necessitate the use of a separate comb, and it is often required to replenish moisture through an external spray device to mitigate excessive dryness. Alternatively, some hair-straightening combs incorporate a steam generator that simultaneously provides moisture during the straightening process. Current steam generators on the market primarily produce high temperatures by heating a conductive plate, which subsequently generates steam through the introduction of clean water. This method tends to produce significant amounts of steam and generates considerable noise as the water evaporates upon contact with the heated plate. Such operational characteristics can detract from the user experience, and the prolonged exposure of the heating plate to both high and low-temperature environments may lead to damage and increased costs.

In order to solve the problems that the steam mode of the existing steam generator has a large amount of steam and generates a lot of noise after the water contacts the high-temperature heating plate and evaporates, the operating experience is poor, the heating plate is easily damaged due to being in a high temperature and local low-temperature environment for a long time, and the cost is higher, the present disclosure provides a steam generator for hair-straightening combs.

Compared with the prior art, the steam generator for hair-straightening combs of the present disclosure has the following advantages.

In the present disclosure, the steam generator for hair-straightening combs includes an evaporation assembly and a heating plate assembly. The evaporation assembly includes an evaporation water tank and a water injection pipe. An evaporation groove and an air-spraying groove communicated with the evaporation groove are arranged in the evaporation water tank, and the heating plate assembly is connected to a side of the evaporation water tank away from the evaporation groove. A first water-storing sound-insulating cotton block is arranged in the evaporation groove and is located between the water injection pipe and the bottom of the evaporation groove, such that the position of the first water-storing sound-insulating cotton block corresponds to the position of the water injection pipe extending into the evaporation groove, thereby enabling the water injection pipe extending into the evaporation groove to sink into the first water-storing sound-insulating cotton block located below the water injection pipe. When water is injected into the evaporation groove through the water injection pipe, the water flowing out of the water injection pipe will first contact the first water-storing sound-insulating cotton block below the water injection pipe, so as to diffuse the water evenly to the bottom of the evaporation groove through the first water-storing sound-insulating cotton block, thereby buffering the water injection and reducing the noise during the water injection. When high-temperature heating is performed at the lower end of the evaporation water tank through the heating plate assembly, the water in each part of the first water-storing sound-insulating cotton block can fully contact the bottom of the evaporation groove to prevent the heating plate from being in a high temperature and local low-temperature environment for a long time and being easily damaged. In addition, since the interior of the first water-storing sound-insulating cotton block is a loose and porous structure, the water is fully contacted in the first water-storing sound-insulating cotton block during the evaporation process, such that steam can be generated more evenly, excessive steam generation can be prevented, and the noise generated during water evaporation can be effectively reduced.

Please refer to. A first embodiment of the present disclosure provides a steam generator for hair-straightening combs, including an evaporation assemblyand a heating plate assembly. The evaporation assemblyincludes an evaporation water tankand a water injection pipe. The evaporation water tankis provided with an evaporation grooveand an air-spraying grooveconnected to the evaporation groove. The heating plate assemblyis connected to the side of the evaporation water tankaway from the evaporation groove. The evaporation grooveis provided with a first water-storing sound-insulating cotton block, and the first water-storing sound-insulating cotton blockis located between the water injection pipeand the bottomof the evaporation groove.

Specifically, one end of the water injection pipeextends into the evaporation groove, and the other end thereof can be connected to an external water injection device, for example, an external water pump can provide clean water to the first water-storing sound-insulating cotton blockin the evaporation groovethrough the water injection pipe. The first water-storing sound-insulating cotton blockis arranged corresponding to the pipe mouth of the water injection pipeextending into the evaporation grooveand is located between the water injection pipeextending into the evaporation grooveand the bottomof the evaporation groove. That is, the first water-storing sound-insulating cotton blockis clamped between the water injection pipeand the bottomof the evaporation groove, which can avoid displacement of the first water-storing sound-insulating cotton blockand improve the stability of the first water-storing sound-insulating cotton block. The water injection pipeand the first water-storing sound-insulating cotton blockare sequentially arranged along the gravity direction, and the first water-storing sound-insulating cotton blockis located at the lower end of the water injection pipe, such that the water flowing out of the water injection pipecan first pass through the first water-storing sound-insulating cotton blockbelow for buffering and diffusion before flowing into the bottomof the evaporation groove. The heating plate assemblyis arranged on the side of the evaporation water tankaway from the evaporation groove, that is, the side of the bottomof the evaporation grooveaway from the first water-storing sound-insulating cotton block.

More specifically, after the operator turns on the hair-straightening comb, the water injection pipedrips clean water into the first water-storing sound-insulating cotton block, and the evaporation water tankis heated by the heating plate assembly. The temperature of the bottomof the evaporation grooveincreases, such that the clean water in the first water-storing sound-insulating cotton blockcontacts the bottomof the evaporation grooveand evaporates. The first water-storing sound-insulating cotton blockcan effectively reduce the noise generated by water evaporation. After the generated steam passes through the upper surface of the first water-storing and sound-insulation block, the steam enters the air-spraying grooveconnected to the evaporation groove, and the steam is sprayed via the air-spraying groove. This arrangement utilizes a straightforward design, consistent operational reliability, and an ability to significantly diminish the noise produced during the evaporation process.

It can be understood that the first water-storing sound-insulating cotton blockis arranged between the water injection pipeand the bottomof the evaporation groove, such that the position of the first water-storing sound-insulating cotton blockcorresponds to the position of the water injection pipeextending into the evaporation groove, and the water injection pipeextending into the evaporation groovecan sink into the first water-storing sound-insulating cotton blocklocated below the water injection pipe. When water is injected into the evaporation groovevia the water injection pipe, the water flowing out of the water injection pipewill first contact with the first water-storing sound-insulating cotton blockbelow the water injection pipe, so as to diffuse the water evenly to the bottomof the evaporation groovethrough the first water-storing sound-insulating cotton block, thereby buffering the water injection process and reducing the noise during the water injection. In addition, when high-temperature heating is performed at the lower end of the evaporation water tankthrough the heating plate assembly, the moisture in each part of the first water-storing sound-insulating cotton blockcan fully contact with the bottomof the evaporation groove, so as to prevent the heating plate from being in a high temperature and local low-temperature environment for a long time and being easily damaged. Further, since the interior of the first water-storing and sound-insulating cotton block is of a loose and porous structure, the moisture is fully contacted in the first water-storing sound-insulating cotton blockduring the evaporation process, such that steam can be generated more evenly, excessive steam generation can be prevented, and the noise generated during water evaporation can be effectively reduced.

Please refer to. Further, the first water-storing sound-insulating cotton blockis higher than the end of the water injection pipeclose to the evaporation groove, and is lower than the highest pointof the evaporation groove.

It can be understood that the first water-storing sound-insulating cotton blockhas a loose porous structure and has a certain degree of expansion and contraction, and the height h(as shown in hin) of the first water-storing sound-insulating cotton blockis configured to be higher than the height D (as shown in D in) of the end of the water injection pipeclose to the evaporation groove. When the first water-storing sound-insulating cotton blockis arranged between the water injection pipeand the bottomof the evaporation groove, at least part of the water injection pipewill directly sink into the first water-storing sound-insulating cotton block, which is more conducive to the full contact between the water flowing out of the water injection pipeand the first water-storing sound-insulating cotton block, and the water flowing out of the water injection pipeis prevented from rushing out of the first water-storing sound-insulating cotton blockand directly impacting the evaporation groove, further reducing the possibility of noise generation. The highest pointof the evaporation groovecan be the height of the notch of the evaporation groove. The height hof the first water-storing sound-insulating cotton blockis required to be lower than the height H (H shown in) of the highest pointof the evaporation groove, so as to provide a flow channel for the steam generated in the evaporation groove.

Please refer to. Further, the evaporation water tankincludes a water tank baseand a water tank cover. The water tank baseis provided with the evaporation grooveand the air-spraying groove. The water tank baseis provided with a steam port. The evaporation grooveis connected to the air-spraying groovethrough the steam port.

It can be understood that the water tank covercan cover the water tank base. The water tank baseis provided with a steam port, such that the steam generated in the evaporation grooveenters the air-spraying groovethrough the steam port. Therefore, the steam passing rate and the passing amount per unit time between the evaporation grooveand the air-spraying groovecan be controlled by the arrangement of the steam port, so as to prevent the occurrence of either excessive or insufficient steam flow into the air-spraying groove, as well as the steam entering the air-spraying grooveat an inappropriate velocity (too much or too little).

Please refer to. Further, a plurality of steam columnsare provided on the water tank cover. The positions of the plurality of steam columnscorrespond to the positions of the air-spraying groove. Thus, the steam enters the air-spraying groovethrough the steam port, and the steam is sprayed through the plurality of steam columns, such that the steam in the air-spraying groovedirectly enters the comb tooth structure through the steam columns, thereby increasing the steam efficiency.

Please refer to. Further, the plurality of steam columnsare arranged at intervals according to a preset arrangement, and the total length of the plurality of steam columnsis less than or equal to the length of the air-spraying groove, such that the plurality of steam columnsafter being arranged match the shape and size of the air-spraying groove, which ensures that each steam columnin the air-spraying groovecan spray steam and that the efficiency and amount of steam sprayed by the plurality of steam columnscan be made more uniform to avoid uneven steam spray affecting the straight hair effect. In addition, by arranging the length of the plurality of steam columnsarranged at intervals to be close to or equal to the length of the air-spraying groove, it can be ensured that the accumulation of steam in the air-spraying grooveis avoided and the manufacturing cost is reduced.

Please refer to. Further, the steam portis located at one end of the evaporation grooveaway from the water injection pipe, such that there is a certain distance between the water injection pipeand the steam port, reserving time for the first water-storing sound-insulating cotton blockto absorb the water flowing out of the water injection pipe, so as to prevent the water flowing into the water injection pipefrom directly flowing into the air-spraying groovethrough the steam port.

Please refer toand. Further, a second water-storing sound-insulating cotton blockis disposed in the evaporation groove. The second water-storing sound-insulating cotton blockis disposed at one end of the evaporation grooveaway from the water injection pipe.

Specifically, the second water-storing sound-insulating cotton block is arranged at one end of the evaporation grooveaway from the water injection pipeand is spaced apart from the first water-storing sound-insulating cotton block. The position of the second water-storing sound-insulating cotton blockis arranged to be offset from the position of the steam port, thereby preventing the second water-storing sound-insulating cotton blockfrom blocking the steam portand affecting the steam entering the air-spraying groove.

It can be understood that clean water is dripped into the first water-storing sound-insulating cotton blockthrough the water injection pipe, and the evaporation water tankis heated through the heating plate assembly. The temperature of the bottomof the evaporation grooveincreases, such that the clean water in the first water-storing sound-insulating cotton blockcontacts the bottomof the evaporation grooveand evaporates. The first water-storing sound-insulating cotton blockcan effectively reduce the noise generated by water evaporation. The generated steam can pass through the upper surface of the second water-storing sound-insulating cotton block and moisten the second water-storing sound-insulating cotton block, and then evaporate simultaneously. The steam enters the air-spraying groovethrough the steam port, and the steam is sprayed through the plurality of steam columns. The structure is simple, the performance is stable, and the noise generated during evaporation can be effectively reduced. After the steam is sprayed from the air-spraying groove, the steam will contact the upper surface of the second water-storing sound-insulating cotton blockand condense into water droplets again, which can achieve effective steam buffering when the device is just turned on.

Please refer to. Further, the second water-storing sound-insulating cotton blockis lower than the highest pointof the evaporation groove.

It can be understood that the height hof the first water-storing sound-insulating cotton blockand the height hof the second water-storing sound-insulating cotton block(as hshown in) are both lower than the height H of the highest pointof the evaporation groove. It can be seen that the first water-storing sound-insulating cotton blockand the second water-storing sound-insulating cotton blockare both lower than the evaporation groove, so as to prevent the internal gas of the first water-storing sound-insulating cotton blockand the second water-storing sound-insulating cotton blockfrom expanding due to internal gas expansion when water evaporates, causing the volume to increase and resulting in the inability to produce steam normally.

Please refer to. Further, an isolation blocking baris arranged between the first water-storing sound-insulating cotton blockand the second water-storing sound-insulating cotton block. The isolation blocking barseparates the evaporation grooveinto a first grooveand a second groove. Part of the water injection pipeextends into the first groove. The first water-storing sound-insulating cotton blockfills the first groove, and the second water-storing sound-insulating cotton blockis located in the second groove. The steam portconnects the air-spraying grooveand the second groove.

Specifically, the isolation blocking barcan separate the evaporation grooveinto a first grooveand a second groovewhich are not connected except for the portion above the groove notch, such that the bottom of the first grooveand the bottom of the second grooveare not connected, and the groove wall of the first grooveand the groove wall of the second grooveare also not connected, thus the steam generated by evaporation in the first groovecan only pass through the upper surface of the first water-storing sound-insulating cotton blockand enter the second grooveto moisten the second water-storing sound-insulating cotton block. The steam portconnects the air-spraying grooveand the second groove, therefore the arrangement of the isolation blocking barnot only separates the evaporation grooveinto the first grooveand the second groovewhich are isolated from each other, but also effectively prevents the clean water flowing into the water injection pipefrom directly flowing into the air-spraying groovethrough the steam portto cause water accumulation.

It should be noted that the first water-storing sound-insulating cotton blockfills the first groove, such that the boundary of the first water-storing sound-insulating cotton blockcan abut against the groove wall of the first groove, thereby enhancing the stability of the first water-storing sound-insulating cotton blockin maintaining the current state. It can also be ensured that the first water-storing sound-insulating cotton blockcompletely covers the bottomof the first groove, so as to ensure the water absorption effect and steam effect of the first water-storing sound-insulating cotton block. Except for the boundary of the second water-storing sound-insulating cotton blocknear the steam port, the remaining boundaries of the second water-storing sound-insulating cotton blockabut against the groove wall of the second grooveand the groove wall formed by the isolation blocking bar, thereby stabilizing the position of the second water-storing sound-insulating cotton block.
