Complete technical specification and implementation details from the patent document.
The present invention relates to a gas combustor, especially to a gas combustor with an igniting and combustion assisting function.
Fire is a must have element in our lives. Fire can be used for cooking food and providing lights, and the fire can also be used for combustion operations such as forging, soldering and welding. Take a gas combustor, such as a refillable lighter or a portable gas stove, as an example, an object can be ignited or food can be cooked. As such, the gas combustor still plays an important role in our lives which cannot be easily replaced.
Take barbecuing as an instance, an igniting source, such as a tinder, is adopted to ignite combustibles, such as charcoals, so that a non-burning status is formed to barbecue foods, such as meats. The combusting efficiency of the tinder is not good, thus the charcoals are not easy to be ignited, and the difficulty bothers the users. As such, the user tries another type of igniting source, such as a gas blowtorch or the aforesaid gas combustor to ignite the charcoals, the gas blowtorch or the gas combustor have advantages of concentrating flame, having firing strength, not easy to be quelled and continuously supplying, thus the charcoals can be rapidly ignited.
As a matter of fact, the necessary condition of combusting objects requires not only the aforesaid igniting source and the combustibles, but a combustion accelerant, such as oxygen, is also needed. In other words, the combustion of combustibles requires the assistance of the combustion accelerant, thus most of the combustion operations require the oxygen. Moreover, it is understood that the wind can also assist the combustion, and the main reason is that the wind brings more oxygen. The air is driven to flow through the combustibles to make the combustibles provided with even more oxygen, thereby enhancing the fire. Accordingly, during the barbecuing process, the user may adopt various types of fanning manners or blowing manners to generate an airflow flowing toward the charcoals after the gas combustor ignites the charcoals, so as to supply oxygen to the charcoals to assist the combustion of the charcoals.

The fuel gas supplying mechanismis defined as a conventional mechanism and includes a gas discharging valvedisposed at the front end of the gas storage tank, a gas conveying soft pipehaving an upstream end thereof sheathed with the gas discharging valve, a gas ejecting nozzledisposed at a downstream end of the gas conveying soft pipe, and a gas discharging press platehaving one end thereof sheathed with the gas discharging valve. The gas discharging press plateis pivotally connected to a pivotal shaftdisposed at a bottom end defined inside the control part.
For regulating the gas supplying amount of the gas discharging valve, a regulation ringis further sheathed with the gas discharging valve. A pull rodis laterally protruded from the regulation ring. The pull rodpasses an elongated regulation slotpreformed in the right shellfor allowing the pull rodto be easily pulled and operated, so that the regulation ringsimultaneously drives the gas discharging valveto be rotated to regulate the supplying amount of the fuel gas.
A press partdisposed at a top end of the ignition switchis radially protruded from an openingof the control part. A piezoelectric deviceis sheathed between a chamberat one side of the ignition switchand a bottom block wallinside the control part. As shown in, when the press partof the ignition switchis pressed, a head partat a top end of the piezoelectric deviceis compressed by the ignition switch, so that the generated high static voltage is transferred by a conducting wirewhich is laterally protruded. An electricity return wireis connected to a bottom end of the piezoelectric deviceand laterally protruded. As such, when the press partof the ignition switchis pressed, another end of the gas discharging press plateis triggered by the ignition switchto generate rotations, thus a leverage effect is generated by the gas discharging press plateto pull out the gas discharging valvefor forming an opened fuel gas supplying status. The liquid gas in the gas storage tankis vaporized to enter the gas conveying soft pipevia the gas discharging valveand then rapidly ejected out from the gas ejecting nozzle, and the ejected gas enters a flame ejecting mechanism.

Furthermore, a buckle hookbuckled with the buckle slotis formed on the ignition switchat a location corresponding to the buckle slot. As shown in, when the ignition switchis in a pressed status, the user presses the continuous switchto compress the first recovery spring, the user stops pressing the ignition switch, and an interfering status is formed between the buckle slotand the buckle hook, so that the ignition witchis unable to return to an initial position, and the ignition switchcontinuously presses the gas discharging press plate, the gas discharging valveis continuously kept to be in the fuel gas supplying status to avoid an inconvenient situation of the user being required to continuously press the ignition switch.
Especially, for enhancing the operation safety of the gas combustor, the gas combustor further includes the aforesaid ignition safety button. A push buttonat a top end of the ignition safety buttonis radially protruded from a front slide slotlocated at a front end of the opening. A second recovery springis disposed between a front end of a seatat a bottom end of the ignition safety buttonand a front block wallinside the front slide slot. A second spring tenonsheathed with the second recovery springis protruded from a front end of the seat. The second spring tenonpasses the front block wallto make the seatsmoothly compress the second recovery spring, thus the second recovery springis enabled to store energy. A rear block sheetof the seatabuts against a flangeaxially protruded from the ignition switch, thus an interfering effect generated by the ignition safety buttonis applied to the ignition switch, and the pressing action is unable to be processed (as shown in). As such, the unlocking difficulty of the ignition safety buttonis enhanced, and children are prevented from directly pressing the ignition switchto lower the possibility of causing a fire accident.

A serial connecting circuit is formed by the battery module, the electric motor, the conducting fixed columnand the conducting elastic memberhaving the elastic connection arm, thus a circuit switch is formed by the conducting elastic memberand the conducting fixed column. In other words, the elastic connection armof the conducting elastic membercontacts with the conducting fixed columnto form a power connection. On the other hand, the power is shut down when the elastic connection armof the conducting elastic memberis separated from the conducting fixed column.
The conducting elastic memberis controlled by the fan switch, and the fan switchis disposed in a rear slide slotlocated at a rear end of the opening. As shown inand, a front tenonand a press memberabutting against the elastic connection armare protruded from a front end of the fan switchand adjacently arranged. In actual practices, the press memberis preferably to be in a reversed-V-shaped slot to allow the elastic connection armto perform an unbiased counterclockwise movement, so that a contacted power supplying status is ensured to be formed by the elastic connection armand the conducting fixed column.
Moreover, a pair of first guide railsare disposed at two sides of the fan switch. The pair of first guide railsare disposed in a pair of first guide slotslocated below the rear slide slotand oppositely disposed as shown in, so that the fan switchis able to axially move in the rear slide slot. When the ignition switchis pressed to be in the operating status, if the fan switchis forwardly pushed in the rear slide slot, the front tenoncontacts with a rear block memberprotruded from a rear end of the ignition switch, so as to form an interfering effect (as shown in). In other words, the ignition switchis in the operating status, the fan switchis unable to be actuated. As such, the ignition switchand the fan switchcannot be simultaneously operated, and the ignition switchand the fan switchcan surely not be operated at the same time.
Moreover, a hollow slotis formed at a central area of the fan switch, and the hollow slotis integrally connected to the fan safety button. The fan safety buttonincludes a U-shaped or an L-shaped elastic supporterconnected to the fan switch. A convex buttonis protruded from a front end of the elastic supporter. A lock boltis radially protruded from the convex button. A lock slotallowing the lock boltto be disposed is radially formed in the rear slide slotat a location corresponding to the lock bolt, so that an interfering effect is provided to lock boltby the lock slot(as shown inand), and the fan switchis unable to be forwardly pushed to form a locking status.
When the ignition switchis not pressed to be in a non-operating status, the fan switchis desired to be operated, the user only needs to press the convex buttonto make the lock boltbe released from the lock slot(as shown in), thus the fan switchis able to be forwardly pushed in the rear slide slot, and a staggering status is formed by the front buttonand the rear block member(as shown in). As such, the press memberpushes the elastic connection armof the conducting elastic memberin the counterclockwise direction to make the elastic connection armbe in communication with the conducting fixed columnto form the power connecting status.
Moreover, the fan switchfurther includes a push sheetinserted on a top surface of the fan switch. Adjacent surfaces of the push sheetand the fan switchare oppositely formed an insertion tenonand an insertion slotcapable of being mutually inserted. The push sheethas a penetrated holeallowing the convex buttonto penetrate and arranged at a location corresponding to the convex button, so that the push sheetdrives the fan switchto simultaneously and axially move.
