Description

Technical Field

[0001] The utility model belongs to the technical field of lighter accessories, and particularly relates to a lighter gasification furnace structure. Background Art

[0002] A lighter gasification furnace generally includes accessories such as an air mixing tube, an air outlet part, and a heat insulation cup. An installation hole is provided at the bottom of the heat insulation cup, the air outlet part is arranged inside the heat insulation cup, and the lower part of the air outlet part passes through the installation hole and is inserted into the air mixing tube. The gas in the gas storage tank assembly is mixed with air through the air mixing tube, and the mixed gas is sprayed into the heat insulation cup through the air outlet part. When the conductive structure is electrified, a spark is emitted into the heat insulation cup to ignite the mixed gas in the heat insulation cup to form a flame.

[0003] The heat insulation cup generally adopts a ceramic cup, which is sintered from porcelain clay. Since the porcelain clay is buried in the sintering filler during the sintering process, the surface of the sintered ceramic cup may be adhered with the sintering filler. If the sintering filler is adhered to the inner bottom surface of the ceramic cup, the sintering filler may be stuck between the inner bottom surface of the ceramic cup and the air outlet part when the ceramic cup and the air outlet part are assembled, which hinders the full contact between the air outlet part and the inner bottom surface of the ceramic cup and reduces the assembly accuracy between the ceramic cup and the air outlet part. Therefore, there is still room for improvement. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a lighter gasification furnace structure, which helps to improve the assembly accuracy between the ceramic cup and the air outlet part.

[0005] The technical solution adopted by the utility model to solve the above technical problem is: a lighter gasification furnace structure, including a ceramic cup and an air outlet part. An installation hole is provided on the inner bottom surface of the ceramic cup. The air outlet part includes a tube body passing through the installation hole and an air outlet head arranged at the upper end of the tube body. The lower end surface of the air outlet head abuts against the inner bottom surface of the ceramic cup, and at least one groove is arranged on the outer side surface of the air outlet head, and the lower end of the groove penetrates through the lower end surface of the air outlet head.

[0006] Preferably, a plurality of grooves are provided, and the plurality of grooves are equally spaced along the circumferential direction.

[0007] Preferably, the air outlet head and the tube body are integrally formed.

[0008] Preferably, a guiding ring is arranged on the outer side surface of the tube body, at least part of the guiding ring is located inside the installation hole, and an inclined guiding surface is arranged on the lower end surface of the guiding ring.

[0009] Preferably, at least one strip-shaped groove is arranged on the outer side surface of the guiding ring, and the strip-shaped groove penetrates through the upper and lower end surfaces of the guiding ring.

[0010] Preferably, the upper end surface of the guiding ring is connected to the lower end surface of the air outlet head, the strip-shaped groove corresponds to the groove, and the upper end of the strip-shaped groove communicates with the lower end of the corresponding groove.

[0011] Preferably, the lower end surface of the guiding ring forms the inclined guide surface by inclining upward from inside to outside.

[0012] Preferably, the guiding ring and the pipe body are integrally formed.

[0013] Preferably, the air outlet part is a zinc alloy air outlet part.

[0014] Preferably, the lower end of the pipe body passes through the mounting hole and is connected to the air mixing pipe.

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] 1. By providing at least one groove on the outer side surface of the air outlet head, and the lower end of the groove penetrates through the lower end surface of the air outlet head, the contact surface between the air outlet head and the inner bottom surface of the ceramic cup is reduced, thereby reducing the possibility of the air outlet head pressing on the sintered filler. If the air outlet head presses on the sintered filler, the air outlet part or the ceramic cup can be rotated to make the sintered filler enter the groove, thus reducing the influence of the sintered filler on the assembly and helping to improve the assembly accuracy between the ceramic cup and the air outlet part;

[0017] 2. By providing at least one strip-shaped groove on the outer side surface of the guiding ring, and the strip-shaped groove penetrates through the upper and lower end surfaces of the guiding ring, the strip-shaped groove can play an avoidance role. When the pipe body passes through the mounting hole, the possibility of the pipe body colliding with the sintered filler in the mounting hole can be reduced, and friction and wear are reduced, so as to ensure the service life of the lighter gasifier, and at the same time help to improve the assembly efficiency.

[0023] The following further describes the present utility model in detail in conjunction with the embodiments of the accompanying drawings.

[0024] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

During the process of pressing the air outlet part 2 into the ceramic cup 1, if there is sintered filler at the bottom of the ceramic cup 1 and the sintered filler is located below the air outlet head 22, the sintered filler can cause the air outlet head 22 to deform. The area of the lower end surface of the air outlet head 22 in contact with the sintered filler bends upward and expands laterally at the same time. The widths of the two grooves 221 close to the sintered filler will be shortened, that is, it can ensure that the air outlet head 22 is in full contact with the inner bottom surface of the ceramic cup 1, thereby ensuring the assembly accuracy between the ceramic cup 1 and the air outlet part 2.

[0028] During assembly, the air outlet part 2 is inserted into the ceramic cup 1 from top to bottom. The pipe body 21 passes through the lower end and passes through the installation hole 11 and then is connected to the air mixing pipe 3.
