Description

 Disposable lighter with safety protection

 Technical field

 The utility model relates to a lighter, in particular to a disposable lighter with safety protection function. Background technique

 A commonly known disposable lighter refers to a pocket lighter, and the body is made of resin materials such as AS, ABS, and PS. Disposable gas lighters are available in a variety of forms. The common structures of various disposable lighters are: casing, hood, ignition device (finished machine head), gas guiding device, etc., which generate gas under the joint action of these structures. Flow and ignite. For example: A lighter with a conventional spark wheel requires the user to rotate a toothed spark wheel against a flint to create a spark, then the user presses the starter plate to infuse the gas and create a flame; another for a disposable lighter The ignition device uses a common ignition device to ignite the gaseous fuel. Since the user presses down forcefully, the starter plate causes the fuel to start flowing and the ignition process begins.

 Safety design associated with disposable lighters (ie, safety precautions designed to prevent children from catching fire), such as the following prior patent: Bulletin No. 579413, 'Lighter with Deflection Door Lock to Prevent Children's Use,' Announcement No. 568247 "The Structure of Lighter Safety", Announcement No. 542332, "Safety Device for Lighters and Children's Use", Announcement No. 442637, "Safety Structure Device for Lighters", Announcement No. 422309, "Safety Improvement Structure for Lighter-type Lighters", Announcement No. No. 339148, "Improved Lighter Safety Mechanism", Announcement No. 328824, "Safety Lighter for Avoiding Young Children", Announcement No. 324513, "Safety Lighter for Tubes", Announcement No. 265840, "Safety Lighter for Preventing Young Children"... … and many more. Various security structures add to the difficulty of an unintentional operator or the difficulty of being operated by an unintended user, while at the same time being intentional to the user for intentional operation and intended user action. However, the disposable lighter with the added safety structure described above has a complicated structure, is inconvenient to operate, and has a high cost. Summary of the invention

In view of the disadvantages of the prior art, the object of the present invention is to provide a security protection function. Disposable lighter, which is simple in structure, easy to operate and low in cost.

 In order to achieve the above object, the technical solution of the present invention is: a disposable lighter having a safety protection function, comprising a fuel-filled body and a machine head for ignition, wherein the machine head is provided with a pressurization The bridge plate for discharging fuel is coupled with a latch member under the bridge plate, and a protective device capable of blocking or allowing the latch member to move downward is correspondingly disposed on the fuselage.

 The guard is a movable planar spring in which a recess for inserting the latch member is provided.

 The recess has a diameter of 2 to 3 mm larger than the latch member.

 The planar shrapnel is coupled to a V-shaped shrapnel that is restricted from being placed in a chamber of the fuselage.

 The angle of the V-shaped shrapnel is greater than 30 degrees and less than 90 degrees.

 Compared with the prior art, the utility model is correspondingly provided with a protection device capable of blocking or allowing the latch member to move downward on the fuselage. When the guard device allows the latch member of the bridge plate to move downward, the utility model can be pressed down. When the ignition is started, when the guard blocks the latch of the bridge plate from moving downward, it cannot be pressed and ignited. DRAWINGS

 The present invention will be further described in detail below with reference to the accompanying drawings.

 Figure 1 is a perspective view of the utility model;

 Figure 2 is a side view of the guard device of the present invention;

 3 is a top view of the guard device of the present invention

Referring to FIG. 1, FIG. 2 and FIG. 3, the disposable lighter with safety protection function of the utility model comprises a fuselage 1 with fuel and a handpiece 2 for ignition. A windshield 101 for windshield, a tempering ring 102 for adjusting the size of the gas flow, a grinding wheel 103 for rubbing against the flint, and a bridge for releasing the surface valve of the fuselage to release the fuel are provided on the handpiece 1. a plate 104, a latch member 105 is coupled below the bridge plate 104; and a protective device capable of blocking or allowing the latch member to move downward is provided on the body 2, the guard device is The movable planar elastic piece 201 is provided with a notch 202 for inserting the latching member 201. The notch 202 has a diameter larger than the latching member 105 by 2 to 3 mm, and the planar elastic piece 201 is coupled with the V-shaped elastic piece 203. The V-shaped elastic piece 203 is restricted to be placed in the chamber 204 of the airframe 2, and the V-shaped elastic piece 203 has an angle range of more than 30 degrees and less than 90 degrees. A surface valve 205 for closing the gas is provided in the body 2, and the core sleeve is passed through the core sleeve. 206 is a drain core 207 that is coupled to the face valve 205.

 Moving the movable planar elastic piece 201 forward, the notch 202 just coincides with the latching member 105 of the bridge plate 104, and the bridge plate 104 can be pressed downward to start the ignition; when the latching member 105 is in the non-operating position, it is placed at the top The movable planar elastic piece 201 is body-mounted such that the movement of the bridge plate 104 is restricted. The V-shaped elastic piece 203 integrally forms a spring function with the movable planar elastic piece 201. When the ignition is performed, the V-shaped elastic piece 203 is automatically extended backward, so that the movable planar elastic piece 201 is synchronously moved back and reset, so that the lighter returns to the original position in a safe state. If you need to ignite again, you need to repeat the above actions.

 The utility model has the following effects:

 1. It can obviously enhance the safety protection effect of the lighter without changing the structure of the original simple lighter.

 1. With the addition of simple components, the purpose of setting up the safety switch can be achieved.

 3. Easy to operate.

 4. Low cost.

 5, can effectively prevent children from accidents when playing.

 6. It can effectively prevent the danger of the overflow of butane gas when the bridge platen is improperly pressurized during handling or in the pocket.

 7. Practical and economical, it can be fully utilized and promoted in practice.
