Technical Field

[0001] The utility model relates to the technical field of gas appliance equipment, in particular to a gas device for preventing flame from burning an igniter. Background Art

[0002] A gas device is a device that sprays compressed combustible gas stored in a container through a gas valve in a certain way, and then ignites it through the temperature generated by the discharge of a high-voltage electronic igniter to produce a flame.

[0003] In the prior art, such as Chinese Patent Publication No. CN217540729U, a gas device for preventing flame from burning an igniter is disclosed, which includes an igniter and a burner head. The characteristics are that the igniter and the burner head both protrude above the gas platform, the igniter is located on one side of the burner head, the burner head is connected to the ventilation opening below the gas platform, and the height of the burner head protruding above the gas platform is greater than the height of the igniter protruding above the gas platform; there are multiple air outlets at the top of the burner head, each air outlet is communicated with the ventilation opening, and the height of each air outlet from the gas platform is greater than the height of the igniter protruding above the gas platform. The disclosed gas device for preventing flame from burning an igniter in this utility model extends the service life of the igniter by the way that the burning combustible gas is far away from the igniter.

[0004] Although the above patent extends the service life of the igniter by the way that the burning combustible gas is far away from the igniter, however, the existing gas device mainly relies on an electronic igniter to ignite the sprayed gas. Although the service life of the igniter can be improved by controlling the distance between the sprayed combustible gas and the igniter, the temperature generated during the combustion of the combustible gas will still cause damage to the igniter with limited distance, and the service life needs to be further improved. Therefore, in view of the above problems, we propose a new gas device for preventing flame from burning an igniter. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that the existing gas device mainly relies on an electronic igniter to ignite the sprayed gas. Although the service life of the igniter can be improved by controlling the distance between the sprayed combustible gas and the igniter, the temperature generated during the combustion of the combustible gas will still cause damage to the igniter with limited distance, and the service life needs to be further improved, and a gas device for preventing flame from burning an igniter is proposed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides a gas device for preventing a flame from burning an igniter, including a middle layer shell 2. A mounting member 21 is fixedly connected at a position near the right side between the inner surfaces of the middle layer shell 2. Slide rods 3 are symmetrically and fixedly connected between the right surface of the mounting member 21 and the right inner surface of the middle layer shell 2. Symmetric bump blocks 22 are fixedly connected at a position near the middle of the inner bottom of the middle layer shell 2. An installation shell 4 is slidably connected between the outer surfaces of the two slide rods 3 near the right side. An electronic igniter 5 is installed inside the installation shell 4. A return button 52 is provided at the bottom of the electronic igniter 5. A bump socket 53 is installed at the bottom of the return button 52. An ignition needle 51 is provided on the left surface of the electronic igniter 5 in a matching manner. Springs 31 are sleeved on the outer surfaces of the two slide rods 3 near the left side. A gas cylinder 1 is installed at the bottom of the middle layer shell 2. A gas valve 11 is provided at the top of the gas cylinder 1 near the left side in a matching manner. A flame concentrating cover 6 is installed at the top of the gas valve 11. A through hole 61 is formed on the outer surface of the flame concentrating cover 6 near the right side. The outer surface of the ignition needle 51 slidably penetrates through the outer surface of the mounting member 21 and extends to the other side. The ignition needle 51 corresponds to the position of the through hole 61. A push knob 41 is fixedly connected at the top of the installation shell 4 near the right edge. The bump socket 53 and the symmetric bump blocks 22 are arranged in correspondence.

[0024] The effect achieved by the entire Embodiment 1 is that the air valve 11 is adjusted to open and close at the bottom of the air tank 1, which is mainly used to discharge the combustible gas in the air tank 1 as fuel. When the device is in use, after pushing the push button 41 to the left, the installation shell 4 can be driven to move leftward on the surface of the slide bar 3. At this time, while the installation shell 4 drives the internal electronic igniter 5 to move leftward, the spring 31 will be compressed and contracted. When the return button 52 that controls the switch of the electronic igniter 5 passes through the symmetric convex block 22, the symmetric convex block 22 will squeeze the convex block socket 53 on the surface of the return button 52 and cause the return button 52 to be squeezed and triggered. At this time, the ignition needle 51 will generate a high-voltage current accompanied by high temperature, pass through the mounting member 21 and the through hole 61, and then ignite the combustible gas inside the flame concentrating hood 6, thus generating a flame. Subsequently, after releasing the push button 41, the reaction force generated by the spring 31 rebounding will push the installation shell 4 to drive the electronic igniter 5 to move to the rightmost position. During this process, the return button 52 will trigger ignition for the second time, improving the ignition stability. When the electronic igniter 5 moves to the rightmost position, it will drive the ignition needle 51 away from the flame concentrating hood 6. The ignition needle 51 after moving away can effectively avoid the temperature generated when the combustible gas burns, thereby greatly improving the service life of the electronic igniter 5. The two sides of the top of the symmetric convex block 22 are inclined downward, and the middle is arc-shaped. The two sides of the bottom of the convex block socket 53 are inclined upward, and the middle is arc-shaped. When the convex block socket 53 squeezes the return button 52 to contract, the lowest point will be higher than the highest point of the symmetric convex block 22. During the staggered process of the two, the surfaces of the convex block socket 53 and the symmetric convex block 22 will slide and fit.

[0025] Embodiment 2, as Figures 1 - 4 shown, a top cover 7 is fixedly connected to the top of the middle layer shell 2. A fire outlet hole 72 is opened at a position near the left side of the top of the top cover 7. The fire outlet hole 72 corresponds to the position of the flame concentrating hood 6. A reserved groove 71 is opened at a position near the right side of the top of the top cover 7. The outer surface of the push button 41 is slidably fitted with the inner wall of the reserved groove 71. The top of the installation shell 4 is slidably fitted with the bottom of the top cover 7. A dust-proof plate 42 is fixedly connected to the position near the top of the left surface of the installation shell 4. The top of the dust-proof plate 42 is slidably fitted with the bottom of the top cover 7.

[0026] The effect achieved by the entire Embodiment 2 is that the fire outlet hole 72 is a reserved outlet for the combustion flame. When the push button 41 is pushed, it will slide inside the reserved groove 71. After the push button 41 is reset under the action of the spring 31, the dust-proof plate 42 on the surface of the installation shell 4 will block the bottom of the reserved groove 71, and the installation shell 4 will block other positions at the bottom of the reserved groove 71. With their mutual cooperation, it can effectively prevent dust from entering the middle layer shell 2 through the reserved groove 71 and causing damage to the device. The structure is simple and the practicability is relatively high.

[0027] Working principle: When this device is in use, after pushing the push button 41 to the left, the installation shell 4 can be driven to move leftward on the surface of the slide rod 3. At this time, while the installation shell 4 drives the internal electronic igniter 5 to move leftward, the spring 31 will be compressed and contracted. When the return button 52 that controls the switch of the electronic igniter 5 passes through the symmetric convex block 22, the symmetric convex block 22 will squeeze the convex block socket 53 on the surface of the return button 52 and cause the return button 52 to be squeezed and triggered. At this time, the ignition needle 51 will generate a high-voltage current accompanied by high temperature, pass through the installation part 21 and the through hole 61, and then ignite the combustible gas inside the flame concentrating cover 6, thereby generating a flame. Subsequently, after releasing the push button 41, the reaction force generated by the spring 31 rebounding will push the installation shell 4 to drive the electronic igniter 5 to move to the rightmost side. During this process, the return button 52 will trigger ignition for the second time, improving the ignition stability. When the electronic igniter 5 moves to the rightmost position, it will drive the ignition needle 51 away from the flame concentrating cover 6. The ignition needle 51 after moving away can effectively avoid the temperature generated when the combustible gas burns, thereby greatly improving the service life of the electronic igniter 5. Moreover, when the push button 41 is pushed, it will slide inside the reserved groove 71. After the push button 41 is reset under the action of the spring 31, the dust-proof plate 42 on the surface of the installation shell 4 will block the bottom of the reserved groove 71, and the installation shell 4 will block other positions at the bottom of the reserved groove 71. With mutual cooperation, it can effectively prevent dust from entering the middle shell 2 through the reserved groove 71 and causing damage to the device. The structure is simple and the practicability is relatively high.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
