Description

A kind of heavy-duty piezoelectric safety lighter

The invention relates to an augmented piezoelectric safety lighter, in particular to a heavy-duty piezoelectric safety lighter with simple structure and preventing fires of children.

Background technique

The piezoelectric lighter of the prior art can be ignited with only a small force, and the blind play of the child is prone to accidents. In addition, it is easy for an adult to automatically ignite due to a mistaken press of a button, causing an accident. However, the piezoelectric lighter with the safety device has a complicated structure and many steps, so it is necessary to provide a piezoelectric safety lighter with a simple structure and convenient use.

Invention disclosure

SUMMARY OF THE INVENTION An object of the present invention is to provide an augmented piezoelectric safety lighter which is simple in structure and convenient to use and has a childproof fire in accordance with the deficiencies of the prior art.

The object of the present invention is achieved by the following technical solutions, which include an open-ended casing, a frame fixedly mounted on one side of the upper end of the casing, and a cylinder, a raft, a gas louver and a casing installed in the casing. The electronic device, and the button mounted on the top of the electronic body, is provided with a baffle in the inner cavity of the frame, and a strong spring acting as a resistance is also arranged between the baffle and the button.

The invention has the advantages that since a strong spring is arranged between the button and the baffle in the frame, when the button is pressed down, the button is subjected to the resistance of the strong spring, and the button is pressed down, from the lower end of the button. The greater the resistance of the strong spring, the greater the force required to press the button, making it difficult for children under the age of five to have enough finger force to suppress the electronic ignition, thereby protecting the child and avoiding the accidental press of the button by the adult. Automatic ignition. Therefore, the invention has the characteristics of simple structure and convenient use. Confirmation DRAWINGS

As shown in FIG. 1 to FIG. 7, the present invention includes a casing 1 having an open upper end, a frame 2 fixedly mounted on one side of the upper end of the casing 1, and a cylinder 3 and a raft 4 installed in the casing 1. The air valve 5 and the electronic unit 6, and the button 7 mounted on the top of the electronic unit 6, are provided with a baffle 21 in the inner cavity of the frame 2, and a strong spring acting as a resistance is also arranged between the baffle 21 and the button 7. 8. As shown in the first embodiment shown in FIG. 1 and FIG. 2, the baffle 21 is formed at the rear end of the inner cavity of the frame 2. In the fire state, the lower end of the strong spring 8 is pressed against the baffle 21, ' Its upper end is pressed against the lower end surface 711 of the sliding sleeve 71 of the button 7. As shown in the second embodiment shown in FIG. 3 to FIG. 5, the baffle 21 is formed at the rear end of the inner cavity of the frame 2. A brace 211 is formed on the baffle 21, and a strong spring 8 is sleeved on the stud. 211, a sleeve 72 is formed on the button 7 directly above the protruding post 211, and the protruding post 211 is sleeved in the sleeve 72. In the fire state, the stud 211 is sleeved in the sleeve 72, and the sleeve 72 is sleeved. The lower end face is pressed against a strong spring 8 that is sleeved on the stud 211. In the third embodiment shown in FIG. 6, the baffle 21 is a "U" shaped plate, and the "U" The glyphs 21 are formed on the rear end and the side ends of the inner cavity of the frame 2. After assembly, the electrons 6 pass through the cavity in the middle of the "U" shaped baffle 21, in the "U" shaped baffle A strong spring 8 is placed on either side of the two sides of the 21 such that the lower end of the strong spring 8 is pressed against the shutter 21, and the upper end thereof is pressed against the lower end surface 711 of the sliding sleeve 71 of the button 7. A strong spring 8 may be placed on each side of the U-shaped baffle 21 to press the lower end of the strong spring 8 against the baffle 21, and the upper end thereof is pressed against the sliding sleeve 71 of the button 7. On the lower end surface 711. A strong spring 8 may also be placed at the rear end of the U-shaped baffle 21 to press the lower end of the strong spring 8 against the baffle 21, and the upper end thereof is pressed against the sliding sleeve 71 of the button 7. On the lower end surface 711.

When the first embodiment of the present invention is used, as shown in FIG. 1 and FIG. 2, when the button 7 is pressed down, the lower end surface 711 of the sliding sleeve 71 of the button 7 is pressed down by the strong spring 8, and the button is pressed down. 7. The greater the resistance of the strong spring 8 from the lower end of the button, the greater the force required to press the button 7, making it difficult for children under the age of five to have enough finger force to press the electronic 6 to ignite, thereby protecting the child and avoiding Automatic ignition of an adult due to a pressure key press.

When the second embodiment of the present invention is used, as shown in FIGS. 3 to 5, when the button 7 is pressed down, the sleeve 72 formed under the button 7 is moved downward, so that the stud 211 is inserted into the sleeve. Inside the barrel 72, the lower end surface of the sleeve 72 compresses a strong spring 8 that is sleeved over the stud 211. As the button 7 is pressed down, the resistance of the strong spring 8 from the lower end of the button is greater, so that a larger force is required to press the button 7, so that it is difficult for a child under five years old to have sufficient finger force to press the electronic 6 to ignite, thereby protecting Children can also avoid auto-ignition caused by accidental pressing of buttons.

When the third embodiment of the present invention is used, as shown in Figs. 6 and 7, when the push button 7 is pressed down, the strong springs 8 on both sides and the rear end of the "U"-shaped baffle 21 are simultaneously compressed. , From It is necessary to press the button 7 with a large force, so that it is difficult for a child under five years old to have enough finger force to press the electronic 6 ignition, thereby protecting the child, and also avoiding the automatic ignition caused by the accidental pressing of the button by the adult. When the structure of the strong spring 8 is placed on either side of the "U"-shaped baffle 21, the working principle is the same as above.

The above are several preferred embodiments of the present invention. According to the disclosure of the present invention, some similarities and alternatives can be apparently apparent to those skilled in the art (such as between the sleeve and the stud of the second embodiment). Alternatives to structural positional shifting) should fall within the scope of the present invention. Industrial application
