Abstract

A button blocking type safety device in a lighter comprises a button (1), a piezoelectric igniter (9), a button push pin (10). Said push pin (10) comprises a first push pin (101) in the middle, a second push pin (102) close to a casing, and a third push pin (103) on which a axis is provided. It further comprises a clasp (4), whose end is positioned in a positioning point (5) opposite the casing adjacent the second push pin (102), and the other end of the clasp (4) is connected with the axis via a positioning spring (3). When the end of the clasp (4) is in the positioning point (5) the button push pin (10) can be blocked; when the end of the clasp (4) is moved close to the second push pin (102) the button push pin (10) can be depressed. The clasp must be push upwardly before igniting the lighter, thus prevent the children easily operating the lighter.

Description

Blocking button type safety device in lighter

The present invention relates to a lighter, and more particularly to a safety device in the lighter prior to ignition. technical background

Internationally, the United States fully implemented the CR Act in 1994. Since the EU imposed two taxes on the import of disposable lighters in 1995 and 1999, in 2002, the lighter with a duty of less than 2 euros had to be installed with a safety lock (CR Act). ). The so-called CR (CHILDR ESISTANCE) Act refers to the installation of a child-proof device on a lighter to improve the safety of the lighter.

The existing lighters have a variety of styles, there are many kinds of open lids and ignition buttons; as can be seen from Figure 1: it is a commonly used lighter, mainly by button 1, burner 6, gas rod 7, storage The gas chamber 8, the piezoelectric igniter 9, and the button ejector pin 10 are composed. Its button ejector pin 10 is an inverted "mountain" word, the width of the thimbles on both sides (102, 103) is slightly larger than the width of the shell shape of the piezoelectric igniter 9, and the thimble 101 in the middle can contact the piezoelectric The upper cover of the igniter 9; when the button 1 is pressed downward, the middle ejector pin 101 on the button needle 10 is pushed to the piezoelectric igniter 9, and the piezoelectric igniter 9 is pressed downward, and the lighter can be fired at this time. However, this type of lighter is not good for a 5-year-old child because he can easily ignite and pose a safety hazard. Summary of the invention

The technical problem to be solved by the present invention is to provide a barrier button type safety device in a lighter, which aims to solve the above drawbacks.

In order to solve the above technical problem, the present invention is achieved by the following technical solutions:

The invention includes a button, a piezoelectric igniter, a button ejector pin; the button ejector pin includes a middle first ejector pin, a second ejector pin adjacent to the outer casing and a third thimble; and a shaft mounted on the third thimble; The utility model comprises a buckle ring; one end of the buckle ring can be positioned at a position opposite to the outer casing of the ejector pin, and the other end of the buckle ring is connected with the shaft through a positioning spring; when one end of the buckle ring is at the positioning point, the button ejector pin card Live; when one end of the buckle moves closer to the second ejector pin, the button ejector pin can be pressed down;

Compared with the prior art, the invention has the beneficial effects that: since the step of pushing up the buckle before the ignition, a lock is added to the safety, ensuring that the child with weak safety awareness can not successfully fire, and the person and the person are guaranteed. Property security. DRAWINGS

3A to 3E are diagrams showing the process of unlocking, igniting, and restoring the lighter. detailed description

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

2, the present invention includes a button 1, a piezoelectric igniter 9, a button ejector 10; the button ejector pin 10 includes an intermediate first ejector pin 101, a second ejector pin 102 and a third ejector pin 103 that are similar to the outer casing; The third ejector pin 103 is mounted with a shaft 2; a buckle 4 is further included; one end of the buckle 4 can be positioned at an opposite point 5 of the housing adjacent to the ejector 102, and the other end of the buckle 4 is positioned. The spring 3 is in contact with the shaft 2; when one end of the buckle 4 is at the positioning point 5, the button ejector pin 10 is stuck; when one end of the buckle 4 is moved closer to the second ejector pin 102, the button ejector pin 10 can be pressed downward.

The principle of the invention is as follows:

When the buckle is fixed at the positioning point, the user applies the pressing button. Since the button and the buckle are connected through the points on the shaft, the piezoelectric igniter cannot be triggered and the fuel in the air chamber is activated, and the lighter is locked. ;

When the user pushes the buckle off the positioning point and rotates 180 degrees around the axis, the user applies a force pressing button to trigger the piezoelectric lighter to excite the generated electronic fire, and simultaneously exerts a force on the gas pressure rod to excite the gas in the gas storage chamber, the lighter It can be fired normally when there is electricity and gas;

When the user pushes the buckle around the shaft and returns to the position below the positioning spring, the lighter can be reset and locked again.

The state and use of the lighter of the present invention can be divided into the following parts:

Lighter lock

As shown in Fig. 3A, the buckle is in the locked state, the lighter is in the locked position, and the user applies the force to press the button. Since the button and the buckle are connected through the points on the shaft and are on both sides of the shaft, the piezoelectric ignition cannot be depressed. That is, in this state, the lighter is in a state of no fire and no gas, and the lighter is in a locked state.

Lighter unlock

As shown in FIG. 3B and FIG. 3C, the user unlocks the buckle by: the user pushes the buckle off the positioning point and rotates 180 degrees around the point on the shaft. The buckle and the button are located on the same side of the shaft, and the user can press the button. Button, then the lighter is unlocked. Lighter fire

The whole process of the lighter is shown in Figure 3D. The user presses the push button to trigger the piezoelectric lighter to stimulate the generation of the electronic fire. At the same time, the gas is excited to activate the gas in the gas storage chamber. The lighter is energetic and gas-filled. In case of fire, it can be fired normally.

Lighter reset lock

The reset process of the lighter is shown in Figure 3E: the user only needs to return the buckle to the initial horizontal position, and the button is on both sides of the shaft, the piezoelectric igniter cannot be pressed, and the lighter is locked again.
