Invention Examples

Embodiments of the invention

[0036] The following further describes the embodiments of the present invention with reference to the accompanying drawings:

[0037] As shown in the figure, the present invention provides a lighter gun. The lighter gun includes an air outlet pipe 5, a gripping portion 1, and a housing 3. The ignition bracket 6 provided in the housing is integrally fixed, that is, the ignition bracket 6 The front end is fixedly connected to the air outlet pipe. The lower side of the ignition bracket 6 is fixedly disposed on the gas storage tank, and the gas storage tank is disposed in the holding part, and then the ignition support is covered by the shell to form a handheld lighter, and the holding part A support seat 2 is provided at the bottom, which can be placed directly upright.

[0038] The entire ignition bracket 6 is approximately T-shaped and has a certain inclination. The front end is used to fix the air outlet pipe 5, and the rear end is provided with an electronic clip 11 inside, and is provided on the outer side of the rear end. An ignition mechanism configured with a slip fit is provided. The ignition mechanism includes a push button switch 4. The inside of the push button switch is locked with one end of the electronic clip, that is, a card slot is formed at the bottom of the push button switch. Forming a snap fit, the button switch 4 will touch the electronic clip when it slides, so that it generates electric sparks. At the same time, the trigger end 13 of the springboard is set on the sliding route of the button switch 4, and the springboard 8 is inverted 7 Shape, and one end of the springboard 8 is snap-connected to the air outlet 10 of the gas storage tank, and the other end is a triggering end 13, which is set on the moving route of the push button switch. When the pushbutton switch moves, it will open the gas storage tank through the springboard. The gas outlet of the gas storage device realizes gas output.

The groove slides, thereby realizing the triggering mode of the push button switch.

[0042] The guide groove includes a first chute 18 provided in a circumferential direction and a second chute 19 provided perpendicular to the first chute. The button switch and the first chute form a circumferential rotation fit, and When the slider of the button switch is located in the first chute, the button switch can only rotate but cannot move in the axial direction. Therefore, the first chute is used to axially limit the button switch, and the second chute is vertical to the first slide. Slot setting, when the button switch is rotated to the junction of the first slot and the second slot, the button switch can move axially along the second slot at this time, and the first slot and the second slot are used to realize Lock and unlock button switches.

[0043] The transition between the first chute and the second chute is a circular arc, and the transition between the two is a circular arc, and the button switch is smoother when switching between rotation and pressing.

[0044] In addition, a gear slot 20 is provided at both ends of the first chute. When in operation, the button switch slides from each gear slot along the first chute to another gear slot. The feel of shifting gears allows users to better determine whether to rotate into position.

[0045] The slider is a pin fixedly connected to the button switch, and the pin can be riveted on the button switch or directly inserted on the button switch, that is, a connection hole 26 is provided on the inner wall of the button switch. The shaft is fixedly disposed in the connection hole, and is located in the guide groove, and can slide along the guide groove.

[0046] A plurality of reinforcing ribs 21 are circumferentially provided on the outer surface of the rear end of the ignition bracket and the button switch. Contact, reduce friction, make the button switch rotate more smoothly, and there is no frustration during rotation.

[0047] The upper end of the springboard 8 is a U-shaped structure, and the uppermost end is bent to form an arc end, and the arc surface of the arc end and the button The switch contacts and is locked on the outside of the ignition bracket 6 and located on the moving path of the push button switch. The top end of the lower end is limited by the stopper of the gas storage tank, and a linkage groove 12 is opened in the middle. The diameter of the linkage groove is determined by The grooves of different sizes are formed. In use, the smaller diameter grooves cooperate with the air outlet of the gas storage tank. When the springboard forms a lever, the air outlet can be opened or closed.

[0048] The bottom end of the ignition bracket 6 is fixed on the gas storage tank, and at the same time, a gas outlet bracket 7 is provided in the ignition bracket 6, the gas outlet bracket 7 is a 7-shaped structure, and it is a sealed structure with an opening above and below. The gas outlet of the gas storage tank is connected, and its upper end communicates with the gas outlet pipe through a seal ring, thereby ensuring the tightness of the gas pipeline between the gas outlet pipe and the gas storage tank.

[0049] At the same time, the gas outlet bracket 7 is directly provided and fixed by the ignition bracket 6, two sides of the gas outlet bracket extend outward to form a limiting block 14, and a limiting groove 23 adapted to the limiting block is provided in the ignition bracket. . The limit block and the limit slot are used to limit the air outlet bracket, and at the same time, it can play a certain fixed role. The air outlet of the gas storage tank, that is, the air outlet needle tube is inserted into the opening at the bottom of the air outlet bracket. It is sealed by a plurality of sealing rings 15. At the same time, the sealing ring can also play a certain fixing role. An upper end is provided with an opening at the prescribed position of the outlet pipe, and the opening is obtained through a sealing ring between the opening and the outlet pipe on the ignition bracket. The sealing sleeve is connected so that the outlet pipe is a completely sealed gas channel.

[0050] The casing is two, and the ignition bracket is symmetrically covered, and the rear end of the casing covers a part of the ignition mechanism, the front end of the casing is embedded in the air outlet pipe, and the bottom of the casing and the grip are The two parts cover the entire ignition bracket, and the two are fixedly connected by screws when they are closed.
