[0002] A gas stove is a kitchen appliance that uses gas fuels such as liquefied petroleum gas and natural gas for direct fire heating. It is widely used in both home and commercial kitchens. When the gas stove is working, the gas enters the stove from the air inlet pipe, enters the burner after being adjusted by the gas valve, and is mixed with a portion of air. The mixed gas is ejected from the fire hole of the ignition distributor and ignited by the ignition device to form a flame.

[0003] Gas stoves are essential kitchen equipment, so their safety is particularly important. Air tightness is one of the key indicators of gas stove safety. Only products that pass the test are qualified and put into the market. Currently, the commonly used air tightness testing methods include water immersion method and pressure change method. The water immersion method has a slow detection speed and may cause damage to the product; the pressure change method is limited by the shortcomings of low detection accuracy and complex operation.

[0004] The above detection method cannot meet the requirements of efficient, accurate and safe detection of modern gas stoves, so it is necessary to provide a gas stove air tightness detection device with high accuracy and simple operation. Utility Model Content

[0006] The present application provides a gas stove air tightness detection device adopts the following technical solution:

[0007] A gas stove air tightness detection device comprises a working platform for positioning and placing the gas stove, a mobile frame body lifted and installed on the working platform, and a detection component arranged on the mobile frame body, wherein the working platform is provided with a first sealing member for sealing an air inlet pipe of the gas stove, and the first sealing member is provided with a delivery pipe for inputting gas into a gas pipeline of the gas stove, the mobile frame body is provided with a second sealing member for sealing a nozzle of the gas stove, and the gas leakage of the gas pipeline is detected by the detection component.

[0008] By adopting the above technical scheme, when using the above detection device to detect the air tightness of the gas stove, the gas stove is positioned and placed on the working platform, the first seal is activated, the air inlet pipe of the gas stove is sealed and blocked, the mobile frame is lowered vertically downward, the detection component and the gas pipe are aligned, gas is delivered to the delivery pipe, and the detection component detects whether the gas leakage per unit time from the air inlet pipe to the regulating valve is qualified; after the front end is qualified, the regulating valve is opened, the second seal is activated, and the multiple gas nozzles of the gas stove are sealed and blocked. At this time, the detection component can detect the gas leakage per unit time from the regulating valve to the gas nozzle. The above detection device can detect the two sections of the gas pipeline of the gas stove, and the operation is simple and the detection accuracy is high.

[0009] Optionally, the working platform has a mounting frame for mounting the first sealing member, and when the gas stove is mounted on the working platform, the output end of the first sealing member corresponds to the air inlet pipe of the gas stove.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses a gas stove air tightness detection device.

[0035] Reference Figure 1 A gas stove air tightness detection device is used to detect the air tightness of a gas stove 4, including a working platform 1, a mobile frame 2 and a detection component 3.

[0036] Reference Figure 2The structure of the gas stove 4 is consistent with the prior art, and includes a gas base 41, a gas pipeline 42 disposed on the gas base 41, a gas nozzle 43 connected to the gas pipeline 42 and used to spray gas, and a regulating valve 44 used to adjust the gas output. The gas pipeline 42 includes a first section 421 and a second section 422. One end of the first section 421 is used to communicate with an external gas source, and the other end is connected to the input end of the regulating valve 44. One end of the second section 422 is connected to the output end of the regulating valve 44, and the other end is connected to the gas nozzle 43. The portion of the first section 421 extending out of the gas base 41 is defined as an air inlet pipe 423. The air inlet pipe 423 is located at the bottom of the gas base 41 and is arranged horizontally.

[0037] Combination Figure 3 and Figure 4 Four positioning seats 11 are fixedly installed on the top of the working platform 1, and the four positioning seats 11 are arranged in a rectangular shape. The top of the positioning seat 11 facing the center of the working platform 1 has a positioning groove 111 for positioning the gas base 41. The rectangular area formed by the four positioning grooves 111 is adapted to the size of the gas base 41, so that the gas stove 4 is not prone to shaking when placed on the positioning frame. Among them, when the gas stove 4 is placed on the positioning frame, there is a placement gap 12 between the bottom of the gas stove 4 and the top surface of the working platform 1 for the air inlet pipe 423 to extend out, which is used to facilitate the removal of the gas stove 4.

[0038] A mounting frame 13 is welded or bolted to one side of the working platform 1, and the mounting frame 13 corresponds to the air inlet pipe 423 of the gas stove 4. The mounting frame 13 has a U-shaped cross section in the horizontal direction, and the U-shaped opening faces the air inlet pipe 423.

[0039] A first sealing member for sealing the air intake pipe 423 is fixedly installed in the mounting frame 13. The first sealing member is a cylinder member, defined as a first cylinder 5. The output shaft of the first cylinder 5 corresponds to the air intake pipe 423, and the output shaft also has a delivery channel 51 connected to the air intake pipe 423. The first cylinder 5 is connected to a delivery pipe 52 connected to the delivery channel 51 on the side wall of its output shaft, and the delivery pipe 52 is connected to the detection component 3. The detection component 3 is fixed to the working frame and is a gas leakage detector in the prior art. The gas leakage detector can deliver gas with a certain pressure to the air intake pipe 423 through the delivery pipe 52, and then detect the leakage amount of the gas per unit time.

[0040] The bottom of the mobile frame 2 is provided with a plurality of second sealing members for sealing and blocking the gas nozzle 43. The second sealing member is a cylinder member, which is positioned as a second cylinder 6. The bottom of the mobile frame 2 is provided with a plurality of L-shaped mounting plates 21 for mounting the second sealing members by bolts.

[0041] Reference Figure 4, multiple second cylinders 6 and gas nozzles 43 correspond one to one, and a sealing head 61 is provided on the output shaft of the second cylinder 6. The sealing head 61 includes a sealing fixing plate 611 fixed to the cylinder body and a sealing rotating column 612 hinged to the sealing fixing plate 611. The sealing rotating column 612 is arranged vertically along the height direction, and the middle part is rotatably connected to the sealing fixing plate 611. The top of the sealing rotating column 612 has an insertion groove 613 for inserting the output shaft of the second cylinder 6, and is penetrated by a fixed shaft 614 of the output shaft.

[0042] The gas nozzle 43 is located on the side of the sealing rotating column 612 facing the second cylinder 6. When the sealing fixing plate 611 is in a vertical state, the gas nozzle 43 can be blocked. When the output shaft of the second cylinder 6 is reset and retracted, the sealing rotating column 612 is driven to rotate away from the gas nozzle 43, and the blocking of the gas nozzle 43 by the sealing fixing plate 611 is released.

[0043] Reference Figure 3 On opposite sides of the working platform 1, lifting driving components 14 for driving the movable frame 2 to move up and down are installed. In this embodiment, the lifting driving components 14 are cylinder components.

[0044] The working platform 1 is also provided with a guide assembly 15 on one side of the lifting drive member 14 for guiding the lifting of the mobile frame 2. The guide assembly 15 includes a guide fixing column 151 fixed to the working platform 1 and a ball sleeve 152 sleeved on the guide fixing column 151. The top of the guide fixing column 151 passes through the end surfaces of both sides of the mobile frame 2, and the ball sleeve 152 is fixedly connected to the mobile frame 2. Among them, the guide fixing column 151 is also sleeved with a buffer elastic member 16 between the bottom of the ball sleeve 152 and the top surface of the working platform 1. In this embodiment, the buffer elastic member 16 is a spring member, which is used to absorb the shaking generated when the mobile frame 2 moves up and down, thereby improving the lifting stability of the mobile frame 2.

[0045] The implementation principle of the gas stove air tightness detection device of the embodiment of the present application is as follows: first, the mobile frame 2 is lifted upward by the lifting drive member 14, so that a space for placing the gas stove 4 is formed between the working platform 1 and the mobile frame 2; the gas stove 4 is positioned and placed on the positioning frame by the handling equipment, and after the placement is completed, the air intake pipe 423 corresponds to the first cylinder 5. Then the mobile frame 2 is vertically lowered so that the second cylinder 6 corresponds to the gas nozzle 43;

[0046] Start the first cylinder 5 to seal and block the air inlet pipe 423 of the gas stove 4, and then deliver gas with a certain pressure to the first section 421 of the gas stove 4 through the delivery pipe 52. The detection component 3 detects the leakage of the gas to determine whether the air tightness is qualified. If it is qualified, the second section 422 is tested. If it is unqualified, the gas stove 4 is removed;

[0047] Start the second cylinder 6 and drive the sealing rotating column 612 to rotate so that the gas nozzle 43 is sealed and blocked. Then open the regulating valve 44 to connect the first section 421 and the second section 422 and continue to deliver gas to the intake pipe 423. At this time, the detection component 3 starts to detect the air tightness of the second section 422, and judges whether the air tightness of the second section 422 is qualified according to the data displayed by the detection component 3.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
