Abstract

The utility model relates to a gas outlet valve for ignition guns and cigarette lighters. The technical scheme includes that the gas outlet valve for ignition guns and cigarette lighters is characterized in that the position of a seal ring on a gas outlet needle is provided with a groove communicated with a neck part of the gas outlet needle when the gas outlet needle is in a natural state, the seal ring is positioned at a non-seal position; and when the gas outlet needle is in an ignition state, the groove on the gas outlet needle is separated from the seal ring, and the seal ring is located at a seal position. When the gas outlet needle is pulled up, the seal ring is immediately separated from the groove of the gas outlet needle to be sealed, and gas can only flow through a vent hole on a lateral wall of the gas outlet needle to flow out through a gas outlet hole arranged in the center of the gas outlet needle. When the gas outlet valve is closed, the gas outlet needle returns to move down by a gas outlet spring, the seal ring just corresponds to the groove of the gas outlet needle, a gas channel is formed between the seal ring and the gas outlet needle, and residual gas can leak out from a port of a nut through the gas channel.

Description

The air outlet valve that is used for burning torch, lighter

Technical field

The utility model relates to a kind of air outlet valve that is used for burning torch, lighter.

Background technology

The general air outlet valve that is used for burning torch, lighter on the present market, comprise air-out needle, sealing ring, go out air spring, nut, passage, venthole, copper seat and T nail, sealing ring tightly is enclosed within outside the air-out needle and is close to the nut inwall, its upper end is limited in the interior shoulder of nut, withstand by going out air spring the lower end, is in sealing state between nut and the air-out needle all the time thereby make.Shown in Figure 1 is exactly the air-out needle stereogram of prior art.

Problem with air outlet valve existence of this structure is: after burning torch (or lighter) uses, air outlet valve has been in closed condition, but the residual air in the air outlet valve also can burn away, generally need the 5-10 fall time of second, do not reach the safety requirements of fray-out of flame in 2 seconds, people are ignored easily and cause and security incident such as fire have potential safety hazard.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of air outlet valve that is used for burning torch, lighter at above-mentioned prior art, automatically the residual air in the air-out needle is discharged at burning torch or lighter igniting finishing back, guarantee that flame extinguished in 2 seconds, to eliminate the potential safety hazard that the ember burning brings the consumer.

The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of burning torch that is used for, the air outlet valve of lighter, comprise nut, the copper seat, go out air spring, passage and venthole, go out between air spring and the nut and be provided with sealing ring, the inner chamber of nut and copper seat constitutes can hold the sliding chamber that air-out needle slides up and down within it, the sealing ring upper end is limited in the interior shoulder of nut, withstand by going out air spring the lower end, it is characterized in that described air-out needle is when nature, air-out needle with sealing ring position of living in the groove that communicates with the air-out needle neck is arranged, sealing ring is in unsealed position; Air-out needle is when fired state, and groove on the air-out needle and sealing ring break away from, and sealing ring is in sealing station.Described groove number is at the 1-6 bar, and optimum is 3.When the air-out needle pull-up, sealing ring promptly with air-out needle on groove break away to form sealing, combustion gas can only be discharged from the venthole at air-out needle center through the passage on the air-out needle sidewall; And when air outlet valve cut out, air-out needle was under the effect that goes out air spring, and resetting moves down, and sealing ring just corresponding to the groove position of air-out needle, forms blast tube between sealing ring and the air-out needle, and residual air can be spilt from the nut oral area by this.

Therefore, use burning torch of the present utility model, lighter, after using, because of the sealing ring in the nut is in the gas leakage state, residual air can spill from the oral area of nut in the air outlet valve, so just seldom has ember to burn away, and has solved the potential safety hazard that the existing universal product may bring because of ember.

Specific embodiment

Below in conjunction with embodiment the utility model is described in further detail.

As Fig. 2, Fig. 3 and shown in Figure 4 is a preferred embodiment of the present utility model.The air outlet valve that is used for burning torch, lighter described in the utility model comprises air-out needle 1, sealing ring 2, goes out air spring 3, nut 4, copper seat 5 and T nail 6, passage 7 and venthole 8, go out between air spring 3 and the nut 4 and be provided with sealing ring 2, the inner chamber of nut 4 and copper seat 5 constitutes can hold the sliding chamber 9 that air-out needle 1 slides up and down within it, sealing ring 2 upper ends are limited in the interior shoulder of nut 4, and withstand by going out air spring 3 lower end.

As shown in Figure 3, air-out needle when nature, air-out needle 1 with sealing ring 2 positions of living in the groove 11 that communicates with air-out needle 1 neck 10 is arranged, sealing ring 2 is in unsealed position, the residual air in the air-out needle 1 can be passed through groove 11, discharges from nut oral area 12.

As shown in Figure 4, when air-out needle 1 pull-up, sealing ring 2 promptly breaks away from the groove 11 of air-out needle 1 and forms sealing, and combustion gas can only be through the passage 7 on air-out needle 1 sidewall, flows out from the venthole 8 at air-out needle 1 center; And when air outlet valve cut out, air-out needle 1 was under the effect that goes out air spring 3, and resetting moves down, the just corresponding groove 11 that communicates with air-out needle 1 neck 10 of sealing ring 2, form blast tube between sealing ring 2 and the air-out needle 1, residual air can be discharged from nut oral area 12 thus.

Groove 11 numbers that communicate with air-out needle 1 neck 10 are at the 1-6 bar, and optimum is 3.

The utility model includes but not limited to the foregoing description.
