Abstract

The utility model discloses a lighter with a safety device, which includes a casing, a base, a gas storage case, a gas outlet valve, a crow plate controlling the start/stop of the gas outlet valve, a piezoelectric device producing the electric spark and a haft. The haft is a rotary canister, on the outer side of which a check ring is positioned. A pressing block for pressing the piezoelectric device and a reposition torsion spring are positioned inside the canister. The reposition torsion spring is positioned between the superface of the canister and the pressing block. A pair of symmetrical convexes is positioned at the bottom of the canister. The lighter can only work normally when the user turns the haft purposely, and spark can be produced by pressing the piezoelectric device, then the crow plate can be pressed by the haft, and the valve can be opened by the crow plate. If the haft is not turned purposely to the working position, then when the haft is pressed, the lighter only produces spark, the crow plate can not be pressed down, and gas outlet valve is not opened, then the lighter can not work properly. The structure of the lighter can prevent accidents caused by the unintended impact of children during play. Therefore the utility model is safe and reliable in application.

Description

A kind of lighter with safety device

Technical field

The utility model relates to a kind of lighter with safety device.

Background technology

Lighter at present relatively more commonly used is to use mixed gas to act as a fuel, and only needs to press hand or slider roller just can the handled easily igniter by beating.Not deliberate operation, as the operation of mistake, children play by beating, perhaps hard thing and press between hand deliberately the collision, all might press skid plate and light lighter, cause disaster accidents such as fire.

Summary of the invention

The purpose of this utility model is in order to prevent playing or security incident that not deliberate igniting action causes of children, and a kind of lighter with safety device is provided.

For reaching above-mentioned purpose, the technical solution that the utility model is taked is, lighter with safety device, comprise casing, pedestal, expansion box, the valve of giving vent to anger, control the skid plate that the valve of giving vent to anger opens and closes, be used for producing the piezo-electric device of electric spark and press hand, it is characterized in that pressing the tube of hand for rotation, the outer wall of tube is fixed with spacing ring, be useful on the briquetting of pressing piezo-electric device and the torsion spring that resets in the tube, the torsion spring that resets is between the end face and briquetting of tube, and there is the projection of a pair of symmetry the lower end of tube.

Beneficial effect of the present invention is:

Lighter with safety device of the present utility model has only to rotate energetically by the user and presses hand, makes when pressing piezo-electric device and producing electric spark, presses hand and just can depress skid plate, makes skid plate open valve, makes the lighter operate as normal.If when using energetically rotation do not press hand, do not allow and press hand and forward the working position to, then press and press hand, can only produce electric spark, and can not depress skid plate, thereby can not open the valve venting, lighter is also with regard to cisco unity malfunction.Therefore the lighter of this structure can prevent children to play or deliberately not collide the accident that causes, and is safe and reliable.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

With reference to accompanying drawing, lighter with safety device comprises casing 12, pedestal 5, expansion box 1, the valve 2 of giving vent to anger, controls the skid plate 10 that the valve of giving vent to anger opens and closes, be used for producing the piezo-electric device 11 of electric spark and pressing hand 8, wherein press the tube of hand 8 (see figure 3)s for rotation, the outer wall of tube is fixed with spacing ring 9, be useful on the briquetting 14 of pressing piezo-electric device 11 and the torsion spring 13 that resets in the tube, the torsion spring 13 that resets is between the end face and briquetting 14 of tube, and there is the projection 3 of a pair of symmetry the lower end of tube.

Shown in Figure 1 is that the top cover 6 of this lighter is not opened and is in the situation of safe mode, this moment, spacing ring 9 was in initial position, in a side of pedestal, rotate the opening part (see figure 4) that two projectioies 3 of pressing hand 8 are in skid plate 10, press hand position and can not allow skid plate 10 be depressed.If will use this lighter, just press and press hand 8 if just open top cover 6, do not depress skid plate 10, therefore can only allow piezo-electric device 11 produce electric sparks owing to press the lower end projection of hand 8, emit gas and can not use air valve 2, thereby lighter is lighted.

Press hand 8 when rotation, when making spacing ring 9 arrive the opposite side of motor seat, the lower end projection of pressing hand 8 this moment is just in time corresponding with skid plate 10, and (seeing Fig. 2, Fig. 5), this moment, lighter was in mode of operation.Press when pressing hand 10, utilize briquetting 14 both can press piezo-electric device 11, make it produce electric spark, can depress skid plate 10 again, open the valve 2 of giving vent to anger and emit gas, thereby lighter is lighted.

As seen, when using this lighter, must the positive rotation of user press hand 8, guarantee by the spacing ring of pressing on hand 9 and rotate the ultimate position.After lighter is finished using, press hand 8 and under the restoring force effect of torsion spring 13, return to initial position, play a protective role.

Claims (1)

1, a kind of lighter with safety device, comprise casing (12), pedestal (5), expansion box (1), the valve of giving vent to anger (2), control the skid plate (10) that the valve of giving vent to anger opens and closes, be used for producing the piezo-electric device (11) of electric spark and press hand (8), it is characterized in that pressing the tube of hand (8) for rotation, the outer wall of tube is fixed with spacing ring (9), be useful on the briquetting (14) of pressing piezo-electric device (11) and the torsion spring (13) that resets in the tube, the torsion spring that resets (13) is positioned between the end face and briquetting (14) of tube, and there is the projection (3) of a pair of symmetry the lower end of tube.
