Problems solved by technology

At present, there are also many kinds of lighters equipped with safety devices. Most of the safety devices are against the wall of the oil tank, the pillars in the oil tank or the steps of the piezoelectric switch. The operating surface of the safety device is smaller than that of the pressing hand, so the operation is not very comfortable.
In addition, the part of the safety device protrudes from the surface of the pressing hand or the outer wall of the oil tank. There is a clear boundary between the two, and the safety device is easy to be seen by children.

Embodiment 1

[0020] Example 1 as Figure 1-6 The shown lighter with a safety switch is located on the wind cover 2 above the oil tank 1. The wall of the oil tank is used as the shell of the lighter, and an air outlet assembly is provided on the same side of the wind cover. Another example is provided with an ignition assembly. The air outlet assembly includes The air outlet needle 11, the air outlet valve 12 and the fire adjustment ring 13 assembled in a conventional manner, the described ignition assembly includes a pressing hand 3 and a piezoelectric switch 4 assembled in a conventional manner, the upper part of the pressing hand 3 is provided with a cover covering its upper surface Safety switch 5, the edge of the safety switch near the wind cover is provided with a safety flange 6 that is in contact with the upper surface of the wind cover, and a return spring 7 is provided between the bottom of the safety switch and the right side wall of the pressing hand. There is an opening groove ...

Embodiment 2

[0022] Example 2 as Figure 7-10 As shown, the difference from Embodiment 1 is that two recesses 14 are arranged at the edge of the windshield near the safety switch, which are arranged symmetrically, and a support piece connected to the windshield is provided under each concave platform 14 15. The safety flange 6 is in contact with the two concave platforms, the cross-sectional size of the insurance flange matches the cross-sectional size of the concave platform, and the upper surface of the safety switch and the upper surface of the windshield adopt a circular arc transition, so that the present invention and There is no difference in appearance of traditional lighters, and the safety switch is more concealed, less likely to be seen by children, and easier to pass the child-proof test.

Abstract

The invention discloses a lighter with a safety switch. The operating surface of the safety device of the existing lighter is smaller than the pressing hand, and the operation is uncomfortable; the part of the safety device protrudes from the surface of the pressing hand or the outer wall of the oil tank, and there is a clear boundary between the two, and the safety device is easy to be seen by children. The present invention includes an oil tank and a wind cover located above the oil tank. An air outlet assembly is provided on the same side of the wind cover, and an ignition assembly is provided on the other side. The ignition assembly includes a pressing handle, which is characterized in that a covering The safety switch on its upper surface is provided with a safety flange against the upper surface of the wind cover near the safety switch edge at the wind cover, and a return spring is provided between the bottom of the safety switch and the side wall of the pressing handle. The safety switch of the present invention has a large operating surface and is comfortable to operate; the safety switch has strong concealment, is not easy to be seen through by children, and is easier to pass the test of preventing children from opening.

Description

technical field [0001] The invention relates to an ignition appliance, in particular to a lighter with a safety switch. Background technique [0002] A traditional lighter is an electronic igniter that uses flammable gases such as butane gas and natural gas as fuel. It includes an oil tank, a windshield above the oil tank, an air outlet assembly and an ignition assembly. Assembled press hand and piezoelectric switch, the air outlet assembly includes the air outlet valve, air outlet needle and fire adjustment ring assembled in a conventional way. It usually directly presses the hand with fingers to make the piezoelectric switch emit electric sparks, and at the same time the air outlet valve releases Flammable gas, lighter sparks. Since it is equipped with flammable liquefied gas, the pressing hand is not restricted without a safety device, and it is very easy to ignite the flammable gas when it is accidentally misoperated, children are playing, or a hard object accidentally ...
