Description

Technical Field

[0001] The utility model relates to the technical field of ignition devices, and specifically relates to a lighter. Background Art

[0002] A lighter is a small fire-taking device, mainly used for lighting fires, smoking, and also for cooking and other fire-taking purposes. The main components of a lighter are a firing mechanism and a gas storage tank; the gas storage tank stores gas and can release the gas in a timely manner, and the firing mechanism is used to eject sparks to ignite the gas. The early firing mechanism was a pulley nitre structure, where the pulley rubbed against the nitre to generate sparks to ignite the gas. The existing lighters usually use piezoelectric ceramics, that is, electric ignition. Pressing the electric ignition can generate sparks, and the sparks ignite the gas to produce combustion. Piezoelectric ceramic lighters are the most common type of lighter because they are safe, environmentally friendly, highly reliable, non-abrasive to the hand, and have a long service life.

[0003] Piezoelectric ceramic lighters have a button. Pressing the button can cause the gas storage tank to release gas, and at the same time cause the electric ignition to emit sparks. Some of the buttons on existing lighters are nested in the shell and are used to ignite the fire by pressing down the button; this type of button-pressing lighter has the problem of being easy to pinch the hand.

[0004] Some buttons have a rotating shaft hinged in the inner cavity of the shell. The button is rotated around the rotating shaft. The lower end of the button has a pressing part, and the pressing part abuts against the firing cap of the electric ignition. When the button rotates downward, the pressing part presses down the firing cap to ignite the fire. The existing rotary buttons are usually arranged on the upper side of the shell. As shown in Figures 10-11 of the attached drawings, they are common existing lighters. There is a problem of a gap between the button and the shell. When the gap is too large, the lighter is not beautiful enough. When the gap is too small, the button and the shell are prone to wear due to friction. This type of button-upper-mounted lighter has the problems of being easy to wear and being easy to pinch the hand; in addition, the windproof device of existing lighters is relatively single and the windproof effect is average. Summary of the Invention

[0005] The purpose of the utility model is to provide a new type of lighter according to the above-mentioned shortcomings, which can solve and overcome the above-mentioned shortcomings.

[0006] The technical solution of the present utility model is realized as follows: A new type of lighter, comprising a housing and a button; the interior of the housing has multiple chambers, including a gas storage chamber, an electric ignition placement chamber, and a valve body chamber; the gas storage chamber is a chamber for storing fuel; an electric ignition is installed in the electric ignition placement chamber, and the electric ignition has a firing cap and a discharge lead. When the firing cap is pressed, the discharge lead can discharge outward; a valve body is installed in the valve body chamber, the upper end of the valve body has a valve core, the lower end of the valve body has an air delivery pipe, and the air delivery pipe extends downward into the gas storage chamber; the top end of the valve core is a nozzle, and the valve core can move up and down on the valve body. When the valve core extends upward, the valve body opens, and the gas in the gas storage chamber can pass through the air delivery pipe and the valve body and finally be discharged from the nozzle; the discharge lead of the electric ignition is close to the nozzle, and when the electric ignition fires, a point discharge can be generated between the discharge lead and the nozzle.

[0007] There is a lever vacancy between the electric ignition placement chamber and the valve body chamber in the housing. A lever is installed inside the lever vacancy, and a top plate is also provided in the lever vacancy. The lever is placed on the top plate to form a fulcrum, so that the lever can rotate around the fulcrum. The lever has a left end and a right end. The right end of the lever is placed under the firing cap of the electric ignition, and the left end of the lever is placed under the valve core.

[0008] When the firing cap is pressed downward, the firing cap presses down the right end of the lever. The right end of the lever descends, and the left end rises, lifting the valve body upward to open the valve core to release the gas. Then the firing cap continues to be pressed to emit a spark, and a point discharge is generated between the discharge lead and the nozzle to ignite the gas to complete the ignition.

[0009] The button is installed on the surface of the housing. The button is in a "π" shape structure and has a rotating end and a pressing end. The rotating end is installed at the lever vacancy through a pin shaft, and the button can rotate around the pin shaft. The pressing end of the button abuts against the firing cap. When the button is toggled, the button rotates downward around the pin shaft and enters the inner cavity of the housing downward, and the pressing end of the button abuts against the firing cap to press down and fire.

[0010] Furthermore, during the process of toggling the button, it does not fit with the surface of the housing.

[0011] Furthermore, the lower outer wall of the gas storage chamber has an inflation port through which the gas storage chamber can be inflated.

[0012] Furthermore, a windproof device is installed at the nozzle. The windproof device is a tubular structure with a necking part in the middle. There are two small holes at the necking part. The upper end of the windproof device has a combustion chamber, the upper end of the combustion chamber is a fire outlet, and a first metal mesh is installed in the combustion chamber. The discharge lead of the electric ignition faces the fire outlet.

[0013] Furthermore, a second metal mesh is installed inside the lower end of the windproof device.

[0014] The beneficial effects of the utility model are as follows: when the toggle button of the lighter is turned, the toggle button rotates downward and completely enters the inner cavity of the shell, so it has the advantage of not pinching the hand, and the button of the lighter does not fit the shell during the downward toggle process, so there is no dilemma that the gap between the button and the shell is too small and easy to wear, and the gap is too small and not beautiful; the lighter also has multiple windproof settings, which has the advantage of good windproof effect.

[0031] The technical solution of the present utility model will be further described below in conjunction with embodiments.

[0032] As Figure 1 , 2 , shown in Fig. 3, a new type of lighter includes a housing 1 and a button 2; there are multiple chambers inside the housing, including a gas storage chamber 3, an electric ignition placement chamber 4, and a valve body chamber 5; the gas storage chamber 3 is a chamber for storing fuel; an electric ignition 6 is installed in the electric ignition placement chamber, and the electric ignition has a firing cap 6 - 1 and a discharge lead 6 - 2. When the firing cap is pressed, the discharge lead can discharge electricity outward; a valve body 7 is installed in the valve body chamber 5. The upper end of the valve body has a valve core 7 - 1, and the lower end of the valve body has a gas delivery pipe 7 - 2. The gas delivery pipe extends downward into the gas storage chamber; the top end of the valve core is a nozzle 7 - 3. The valve core can move up and down on the valve body. When the valve core extends upward, the valve body opens, and the gas in the gas storage chamber can pass through the gas delivery pipe 7 - 2 and the valve body and finally be released from the nozzle 7 - 3; the discharge lead of the electric ignition is close to the nozzle. When the electric ignition fires, a tip discharge can occur between the discharge lead and the nozzle;

[0033] There is a lever space between the electric ignition placement chamber and the valve body chamber in the housing. A lever 8 is installed inside the lever space, and a top plate is also provided in the lever space. The lever is placed on the top plate to form a fulcrum, so that the lever can rotate around the fulcrum. The lever has a left end and a right end. The right end 8 - 2 of the lever is placed under the firing cap of the electric ignition, and the left end 8 - 1 of the lever is placed under the valve core;

[0034] When the firing cap is pressed downward, the firing cap presses down the right end of the lever, and the right end of the lever descends, as Figure 3 shown by F1 in the figure, the left end rises and upwardly lifts the valve body, as Figure 3 shown by F2 in the figure, to open the valve core to release the gas. Then the firing cap continues to be pressed to generate a spark. A tip discharge occurs between the discharge lead and the nozzle to ignite the gas and complete the ignition;

[0035] The described button 2 is installed on the surface of the housing. The button has a "π" - shaped structure with a rotating end 2 - 1 and a pressing end 2 - 2. The rotating end is installed at the vacant position of the lever through a pin shaft. The button can rotate around the pin shaft, and the pressing end of the button abuts against the percussion cap. When the button is toggled, the button rotates downward around the pin shaft, and the pressing end of the button presses down the percussion cap to strike a fire; when the button is toggled, the button enters the inner cavity of the housing downward, as Figure 4 is the schematic diagram after toggling.

[0036] Usage method and working mechanism: This new type of lighter is used in the following way. When ignition is needed, toggle the button downward. The button rotates downward around the rotating end, and the pressing end of the button presses down the percussion cap of the electric lighter. The percussion cap presses down, and when the percussion cap presses down, it presses the right end of the lever downward, and the left end of the lever rises, lifting the valve core so that the nozzle of the valve core sprays out gas. Then the percussion cap continues to be pressed downward until a spark is generated. A tip discharge occurs between the discharge lead and the nozzle, igniting the gas to complete the ignition; because when the button is toggled, the button enters the inner cavity of the housing downward, this lighter has the advantage of not pinching the hand during use, enhancing the user experience.

[0037] Furthermore, during the toggling process of the button, it does not fit with the surface of the housing.

[0038] Since the button does not fit with the surface of the housing when it is toggled, this avoids the wear situation between the button and the surface of the housing during toggling. It also avoids the situation that if the gap between the button and the housing is too small, it is easy to cause wear due to contact, and if the gap is too large, it is not aesthetically pleasing.

[0039] Furthermore, as Figure 3 shown, the lower outer wall of the gas storage chamber has an inflation port 9, and the gas storage chamber can be inflated through the inflation port.

[0040] Furthermore, as Figures 7-9 shown, a wind - proof device 10 is installed at the nozzle 7 - 3. The wind - proof device is a tubular structure with a neck - constricted part in the middle. There are two small holes 11 at the neck - constricted part. The upper end of the wind - proof device has a combustion chamber 12, and the upper end of the combustion chamber is a fire outlet 13. A first metal mesh 14 is installed in the combustion chamber, and the discharge lead of the electric lighter faces the fire outlet.

[0041] Furthermore, a second metal mesh 15 is installed inside the lower end of the wind - proof device.

[0042] Setting up a windproof device can play a role in wind prevention. The specific principle is as follows: When the lighter is turned on, the gas enters the windproof device from the nozzle and is ejected from the flame outlet. When the gas passes through the constricted part of the windproof device, its speed will increase. According to Bernoulli's principle, the faster the speed, the lower the pressure. Therefore, the internal air pressure of the pipeline at this place is less than the outside world, and the outside air is inhaled from the small holes in the constricted part, fully mixed with the gas, and then enters the combustion chamber together. It is ignited by the spark, and the gas in the combustion chamber expands rapidly, ejecting a more powerful flame from the flame outlet, thus producing a windproof effect; by installing the first and second metal meshes, even if the flame goes out, the first metal mesh and the second metal mesh still have heat, and their heat can still ignite the gas ejected subsequently, which also has a windproof effect.

[0043] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, can make some changes or modifications to equivalent embodiments by using the technical content disclosed above. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
