In the present disclosure, an aerosolizable medium refers to a substance that can be heated to provide an aerosol. The aerosolizable medium includes tobacco material, a composition containing tobacco ingredients or nicotine or flavoring ingredients, such as a liquid composition, a solid composition or a solid-liquid mixture.

Referring to, an embodiment of the present disclosure provides an electronic atomization device. The electronic atomization deviceis configured to heat an aerosolisable medium inside the electronic atomization deviceto form an aerosol for a user to inhale. The following description will be made by taking the electronic atomization devicefor heating a solid aerosolisable medium to generate an aerosol as an example.

The electronic atomization deviceaccording to an embodiment of the present disclosure includes a housing, an atomization assembly, and a power supply assembly.

In one embodiment, referring toand, the housingis provided with an accommodation cavityconfigured to accommodate the power supply assembly, and the housingis provided with a mounting grooveextending through two opposite sides of the housing. The mounting grooveand the accommodation cavityare isolated from each other. One end of the housingis provided with an air outlet hole, and the mounting grooveis provided at one end of the housingaway from the air outlet hole. A groove wall of the mounting grooveis provided with an air passing holein communication with the air outlet hole. The atomization assemblyis detachably inserted into the mounting groove. The atomization assemblyhas an atomization cavityand includes an atomization coreprovided in the atomization cavity. The atomization coreis electrically connected to the power supply assembly. The atomization assemblyis further provided with an air inlet holeand an air vent hole. The air inlet hole, the atomization cavity, the air vent hole, the air passing hole, and the air outlet holeare in communication with each other sequentially. The power supply assemblyis configured to supply power to the atomization assembly. When the power supply assemblysupplies power to the atomization assembly, the atomization corecan heat the aerosolisable medium accommodated in the atomization cavityto generate the aerosol, and then the aerosol is discharged through the air vent hole, the air passing hole, and the air outlet holesequentially for a user to inhale.

The atomization assemblyis detachably inserted into the mounting groove. In this embodiment, the atomization assemblyis detachably inserted into the mounting groovethrough a snap-groove connection. In one embodiment, as shown in, one of an outer wall of the atomization assemblyand the groove wall of the mounting grooveis provided with a buckle, and the other one of the outer wall of the atomization assemblyand the groove wall of the mounting grooveis provided with a locking groovecorresponding to the buckle. The bucklecan be snapped into the locking groove, and the atomization assemblycan be detachably inserted into the mounting groove. In other embodiments, the atomization assemblymay be detachably inserted into the mounting grooveby magnetic attraction structures.

Compared with the fixing manner of magnetic attraction, the present embodiment can avoid that the atomization assemblyis difficult to disassemble due to too strong magnetism, can also avoid that the atomization assemblyis easy to fall off from the mounting groovedue to insufficient magnetism, and can avoid the problems such as an increased cost and an increased device volume caused by the arrangement of the magnetic attraction structure.

As such, when the aerosolisable medium in the atomization assemblyis exhausted or the atomization assemblymalfunctions, the user can easily replace the atomization assembly, and the user can be convenient to use, the risk of scrapping the whole machine due to local damage of the electronic components can be reduced, the service life of the product is prolonged, and the environmental pollution and the resource waste can be reduced. Further, since the mounting grooveextends through the opposite sides of the housing, when removing the atomization assembly, the user only needs to push the atomization assemblywith his fingers to move the atomization assemblyalong an axial direction of the mounting grooves, which facilitates the user's operation and greatly improves the user's experience.

The mounting groovehas a limiting endand a mounting endthat are opposite in an axial direction thereof. Further, in order to prevent the user from inserting the atomization assemblyinto the mounting groovein a wrong direction, that is, in order to ensure that the atomization assemblycan only be inserted into the mounting groovefrom the mounting endrather than the limiting end, in this embodiment, an inner diameter of the mounting endis greater than an inner diameter of the limiting end, and the atomization assemblycan merely be inserted into the mounting groovefrom the mounting end, to prevent the atomization assemblyfrom being inserted into the mounting groovein the wrong direction during mounting.

In another embodiment, an edge of the opening of the limiting endmay be provided with a limiting structure extending into the mounting groove, such as a protrusion or a rib extending from the edge of the opening of the limiting endto a center of the mounting groove. In one embodiment, an inner peripheral surface of the mounting groovemay be configured to extend obliquely along the axial direction of the mounting groove. Such arrangements can also enable the inner diameter of the opening of the mounting endto be greater than the inner diameter of the opening of the limiting end, which is not limited herein.

In this embodiment, in order to avoid misalignment of the atomization assemblydue to mutual rotation when the atomization assemblyis inserted into the mounting groove, referring to, an outer peripheral surface of a portion of the atomization assemblyinserted into the mounting grooveincludes a first anti-rotation surfacethat is flat, and outer peripheral surfaces of other portions of the atomization assemblyare arc surfaces. The air vent holeis formed on the first anti-rotation surface. Correspondingly, a portion of the groove wall of the mounting grooveincludes a second anti-rotation surfacecorresponding to the first anti-rotation surfaceand being flat, and the other portions of the groove wall of the mounting grooveare also arc surfaces. The air passing holeis formed on the second anti-rotation surface. A contour of the groove wall of the mounting grooveis adapted to a contour of the outer peripheral surface of the portion of the atomization assemblyinserted into the mounting groove, and when the atomization assemblyis inserted into the mounting groove, the first anti-rotation surfaceis in contact with the second anti-rotation surface, and the atomization assemblyhas only one mounting direction in the circumferential direction thereof. Therefore, when the atomization assemblyis inserted into the mounting groove, the misalignment due to mutual rotation can be prevented.

It should be understood that the contour of the groove wall of the mounting grooveand the contour of the outer peripheral surface of the portion of the atomization assemblyinserted into the mounting grooveare not limited to the shapes shown in the embodiment, as long as there is an anti-rotation surface, and the atomization assemblycannot rotate after being inserted into the mounting groove.

Referring toand, in one embodiment, a top end of the housingis provided with a mouthpiece, and the air outlet holeextends through two opposite ends of the mouthpiece. The air outlet holeand the air passing holeare coaxially spaced arranged. The electronic atomization devicefurther includes an air vent pipeprovided in the accommodation cavity. The air vent pipeis provided with a main air channelextending through two opposite ends of the air vent pipe, and the air passing holeand the air outlet holeare in communication with each other through the main air channel. The atomization assemblyfurther includes a first sealing memberand a second sealing member. The first sealing memberis made of silica gel and is provided in the accommodation cavityadjacent to the air outlet hole. The second sealing memberis made of silica gel and is provided in the accommodation cavityadjacent to the air outlet hole. The first sealing memberis opposite to and spaced from the second sealing member. The mouthpieceis inserted into a side of the first sealing member, one end of the air vent pipeis inserted into a side of the first sealing memberaway from the mouthpiece, and the other end of the air vent pipeis inserted into the second sealing member. The first sealing memberis configured to prevent condensate generated by the aerosol from flowing back into the housingfrom the mouthpieceand causing a short circuit of the power supply assembly. The second sealing memberis configured to prevent the condensate in the air vent pipefrom flowing back into the atomization assembly.

In this way, by providing the straight-through air vent pipewith no other components in the air vent pipe, compared with the conventional electronic atomization device in which an atomization core in is usually provided in air vent pipe, the above-mentioned structure makes it easier for the user to clean the condensed substances or other impurities remaining in the main air channel. The user only needs to use a straight brush adapted to the mouthpieceto insert the main air channelfrom the air outlet holeat the mouthpiece, and then the straight brush can directly extend through the whole main air channel, and all impurities in the main air channelcan be cleaned out from the air outlet holewithout any residual impurities. The cleaning effect is very good, and there is no need to disassemble individual parts for cleaning, and the cleaning operation is very convenient.

In one embodiment, an outer diameter of the air vent pipeis 0.5 cm to 1 cm. Such an arrangement can be more convenient for arranging various components in the housing, to save space, and is also convenient for selecting suitable cleaning tools to extend into the main air channelto clean the air vent pipe.

It should be noted that since the air vent pipeis a standard member with a constant length. Depths of both ends of the air vent pipeinserted into the first sealing memberand the second sealing membershould be limited, to prevent the other end of the air vent pipefrom falling off from the first sealing memberor the second sealing memberdue to too deep insertion of one end of the air vent pipe. Therefore, referring to, in one embodiment, an outer peripheral surface of the air vent pipeis further provided with a limiting member. One side of the limiting memberabuts against the second sealing member, and an inner peripheral surface of the limiting memberand the outer peripheral surface of the air vent pipehave steps, and the limiting membercan limit the insertion depth of the air vent pipeinto the second sealing member.

It should be understood that the limiting membermay be integrally connected with the air vent pipe, or may be fixedly connected to the air vent pipe, which is not limited herein.

Referring toand, in the illustrated embodiment, the power supply assemblyincludes a batteryand a circuit board. The batteryis provided on one side of the circuit boardand electrically connected to the circuit board. The circuit boardis sleeved on and snapped to the outer wall of the mounting groove, to be fixed in the accommodation cavityof the housing. The circuit boardis provided with at least two electrodes. Referring to, the atomization assemblycorrespondingly has at least two electrode contacts. Each electrodeis electrically connected to a corresponding electrode contact.

In this embodiment, three electrodesare provided, and three electrode contactsare correspondingly provided. Each electrodeabuts against one corresponding electrode contact, to achieve the electrical connection between the power supply assemblyand the atomization assembly. It should be noted that, among the three electrodes, one electrodeis a positive electrode, another electrodeis a negative electrode, and the remaining one electrodecan be configured to reading, writing, collecting, interacting, etc. of information between the atomization assemblyand the power supply assembly, to read information in a chip, a circuit, or a sampling resistor in the atomization assembly, and the circuit boardin the power supply assemblycan control and match different heating modes according to different atomization assemblies.
