Description

Windproof and explosion-proof open fire lighter

Technical Field

The utility model relates to a lighter, especially prevent wind explosion-proof lighter.

Background

Currently, the biggest problem encountered with lighters is safety. The lighter is filled with fuel, and more than 90% of lighter shells on the market are made of plastic, so that the internal pressure of the lighter is increased rapidly at high temperature, and the lighter is easy to explode, particularly when being directly irradiated by the sun or placed in a sunned vehicle. Many lighters fall down even from more than 1.5 meters and explode. This threatens not only the safety of the user but also the safety of the child.

The other lighter is windproof in its most practical function. However, the existing windproof lighter totally uses the windproof tower structure based on Bernoulli principle, not only the cost is high, but also the temperature of the flame sprayed out is as high as 800-1000! It is very easy to scald, especially for children.

How to use the simplest structure, the lowest cost, make the lighter can be explosion-proof and prevent wind, safe and practical promptly, this is the problem that the industry is in urgent need of solving always.

US4531906 discloses a lighter housing provided with a windshield. This lighter casing includes: a hollow housing component adapted to receive a lighter therein through a top opening of the lighter; and a hood member adapted to be received within the housing member and to receive at least a portion of the lighter through an open side portion thereof. The housing member comprises a side opening for facilitating passage of a user's finger through the side opening into the windshield, and the windshield member comprises an open bottom such that the windshield is slidably displaceable in a longitudinal direction relative to the housing member. However, this patent has the following disadvantages: firstly, the wind shield is required to be pushed up from the side when the wind-proof function is used every time, and the wind shield is required to be pressed in by hands after the wind shield is used, which is very inconvenient for users. Secondly, the side of the flame close to the finger operation surface is not protected, so if wind blows from the side of the finger operation surface, the flame can be blown out. And thirdly, when the windproof function is used, the windshield is lifted, and the shell of the lighter is completely exposed by the opening on the side surface of the shell, so that a good explosion-proof effect cannot be achieved. In conclusion, the patent can not play a good windproof role and a good explosion-proof role, and is inconvenient to operate.

Chinese patent CN209310028U provides a windproof lighter, which comprises a lighter body, a slide rail, a slide block, a windproof cover, a push block, a first compression spring, etc.; the left side of the lighter body is provided with a sliding rail, the sliding rail is slidably provided with a sliding block, the left side of the sliding block is provided with a windproof cover, the lower portion of the left side of the windproof cover is provided with a push block, a cylindrical sliding groove is formed in the left side of the lighter body, the right side of the lighter body is provided with a groove, the right side of the groove is communicated with the cylindrical sliding groove, and a first compression spring. The utility model discloses the vertical direction in top both sides wall position of lighter is provided with two guide slots, and the both ends card of preventing wind the baffle is in the guide slot, and the baffle of preventing wind can reciprocate along the guide slot, prevents wind the baffle setting and goes out burner one side at the lighter, prevents wind the baffle and can reciprocate. This solution can be seen as a simplified version of the above patent, but the actual structure is more complex. Compared with the scheme, the scheme simplifies the shell, so that the explosion-proof function is completely absent. Like above scheme, the windshield is opened totally towards the one side of finger operation face, can't play fine windproof effect. The wind-proof function is needed to be pushed up from the side surface every time the wind-proof cover is used, and the wind-proof cover must be pressed in by hands after the wind-proof cover is used, which is very inconvenient for users.

Chinese patent 90222736X discloses a windproof lighter, which has a windshield with a folded edge on the upper edge of the oil groove of the lighter, i.e. around the burner. This patent is the same as the above patent in that the side of the windshield facing the finger-operated surface is completely open and does not provide a good wind-proof function. Moreover, because the windshield is particularly tall and has a large opening, the windshield is very obtrusive, the appearance is very unsightly and even less explosion-proof.

Chinese patent CN203642224U discloses a novel windproof and explosion-proof lighter, the right side middle part of the lighter body is provided with a flame regulator, the upper part of the lighter body is sleeved with an upper protective sleeve, the lower part of the lighter body is sleeved with a lower protective sleeve, and the upper end right side of the upper protective sleeve is connected with a windproof protective plate through a hinge. The lighter is characterized in that the outer part of the lighter is blocked by a windproof protective plate, the flame nozzle of the lighter is designed to be windproof, the lighter is enabled to have a better windproof effect by utilizing a double-layer windproof system, and meanwhile, the periphery of the lighter is additionally provided with a pair of protective sleeves, so that the gas storage tank of the lighter cannot be broken under strong collision. This patent is with a series of complicated settings such as last lag, lower lag, hinge connection's wind-proof backplate, does not count the cost, does not consider production technology to accomplish wind-proof blast proof function, and this is unrealistic at all, and market can not accept. Moreover, this patent, like all the above patents, can only protect flames on three sides, the side away from the finger operation surface is completely open, and the flames are not protected. In addition, the lighter body between the upper protective sleeve and the lower protective sleeve is completely exposed, the internal pressure of the lighter is rapidly increased at high temperature, and the lighter is easy to explode, and a large gap is left between the upper protective sleeve and the lower protective sleeve, so that a user can be injured. So this scheme not only cost is very high, and the safeguard effect is also not ideal moreover.

Chinese patent CN203309931U discloses a scald-preventing, plating-free, high-temperature-resistant, windproof lighter hood, which is an integrally formed hood body, wherein the right side and the bottom of the hood body are provided with openings, and the upper plane of the hood body is provided with a flare hole, and is formed by a special formula of non-metallic material with high-temperature resistance. However, the "high temperature resistant non-metallic material" mentioned in this patent will be very high in cost, will not deform in the combustion test of enduring 500 degrees flame for 2 minutes, and can be mass-produced and formed, and only alumina ceramic is currently preferred in non-metals, but the cost is very high, and is much higher than that of general sheet metal iron. Moreover, the production process is extremely complicated due to the unusually complicated shape. With such a high cost and complex process, it is only wind-proof and not acceptable in the market, and moreover, it is not explosion-proof.

Therefore, the lighter which can be simply used in the hands of consumers, has low cost, safety and simple process and has the windproof and explosion-proof functions can really compete in the market.
