[0002] The gas inlet pipe is a vital part of the gas stove. It connects the gas pipeline and the burner and is responsible for directing the gas into the burner for combustion. Its quality and safety are directly related to the use effect of the gas stove and the safety of the user.

[0003] A Chinese patent with the publication number CN204006165U discloses a dust-proof device for the air intake pipe of a gas appliance, including an air intake nozzle of a gas stove and a cylindrical cap with an open end, the air intake nozzle and the cylindrical cap are plugged in; the characteristics are: the closed end of the cylindrical cap has a circular baffle formed integrally with the cylindrical cap, the diameter of the circular baffle is greater than or equal to the diameter of the gas hose; the circular baffle cooperates with the end of the air intake nozzle to stop. Due to the use of such a structure, after the consumer purchases, when plugging the prepared gas hose into the air intake nozzle, it cannot be plugged in due to the setting of the circular baffle; the plugging can only be achieved when the cylindrical cap is unplugged; the safety hazard caused by forgetting to unplug the cylindrical cap in the prior art is overcome.

[0004] As mentioned above, the patent provides a dust prevention device for the air intake pipe of a gas appliance, which can overcome the safety hazard caused by forgetting to remove the cylindrical cap in the prior art. However, it is often used in the kitchen and there will inevitably be some dust, especially in rural areas. There are also many places where wood stoves are used, and there will be more dust. Using a gas appliance in such an environment will inevitably lead to dust accumulation inside the air intake pipe. If the dust is not handled in time, it will directly affect the use of the gas appliance. Utility Model Content

[0022] The dust collecting bin 3 is used for collecting dust in the dust collecting bin 3, and the dust collecting bin 3 can be disassembled. The supporting baffle plate 4 is connected to one side of the dust collecting bin 2, and the rotating clamping column 5 is fixedly connected to the pneumatic impeller 6. When gas enters, the gas will drive the pneumatic impeller 6 to start rotating, and then drive the rotating clamping column 5 to rotate at the axis of the supporting baffle plate 4. The transmission clamping shaft 7 is connected to one end of the rotating clamping column 5, so that the transmission clamping shaft 7 can rotate with the rotation of the rotating clamping column 5. After the transmission clamping shaft 7 rotates, it drives the transmission clamping cylinder 8 to start rotating, and then drives the connecting clamping rod 9 to cooperate with the scraper light plate 10 to rotate along the inner wall of the dust collecting bin 2, and then the dust on the inner wall of the dust collecting bin 2 is scraped off and enters the collecting bin 3 through the curved sieve plate 11, thereby preventing the dust from entering the air inlet pipe 1, avoiding the problem of the gas appliance being affected by the dust, and thus improving the working efficiency of the gas appliance.

[0024] Through the above technical scheme, the air intake filter plate 12 is clamped on one side of the inner wall of the air intake pipe 1 to further improve the dust filtering effect. The transmission clamp shaft 7 is rotatably connected with the axis of the air intake filter plate 12. When rotating, a rotating round block 13 is fixed at one end of the transmission clamp shaft 7, and a transmission circular groove 14 is provided at the axis of the air intake filter plate 12, so that the transmission clamp shaft 7 is clamped into the transmission circular groove 14 through the rotating round block 13, so that it can be supported while rotating.
