[0002] A household combustible gas detector is a device used to detect indoor gas leaks. It plays an important role in ensuring family safety and predicting risks: the combustible gas detector can predict whether there is a risk of gas leakage. If the indoor gas leakage exceeds the standard, the detector will send out sound and light signals to alarm, reminding residents to eliminate safety hazards in time.

[0003] In the existing public documents, the utility model patent of Chinese patent publication number CN214622505U discloses a household combustible gas detector. A protruding mask is designed on the upper surface of the cover plate of the existing household combustible gas detector, and a fence plate is arranged on the mask as a smoke inlet. Due to its protruding mask structure and fence hollow structure, the whole shell is very bloated and conspicuous, which seriously affects the indoor style design, and the existing combustible gas detector is very troublesome to disassemble and assemble, and it is inconvenient for maintenance; by arranging a fence plate on the mask as a smoke inlet, due to its protruding mask structure and fence hollow structure, the whole shell is very bloated and conspicuous, which seriously affects the indoor style design, and the existing combustible gas detector is very troublesome to disassemble and assemble, and it is inconvenient for maintenance; However, the combustible gas detector also has the following defects;

[0004] When the above-mentioned combustible gas detector is used at home, it needs to be placed in the kitchen, and the gas used in the kitchen is at the gas stove. In particular, cooking will produce a large amount of oil smoke, and the oil smoke can easily block the sensor end of the combustible gas detector with the air, and the service life of the combustible gas detector is greatly shortened. Therefore, it is necessary to provide a household combustible gas detector for detecting liquefied gas. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a household combustible gas detector for detecting liquefied gas.

[0006] To achieve the above object, the utility model provides the following technical solutions: a household combustible gas detector for detecting liquefied gas, comprising a combustible gas detector housing, a curved frame plate is installed on one side of the combustible gas detector housing, and a protective component is installed on the inner wall of the curved frame plate;

[0007] The protection component includes an arc-shaped filter element mesh plate installed on the inner wall of the arc-shaped frame plate, and one end of the arc-shaped frame plate is fixedly connected to a fan-shaped collar block, one side of the fan-shaped collar block and near the middle position thereof is fixedly connected to a rotating rod, the inner wall of the fan-shaped collar block and near the top position thereof is connected to a rotating support screw, and the outer wall of the support screw and a locking nut are threadedly connected to a position on one side of the fan-shaped collar block.

A plurality of alarm lights are installed in front of the combustible gas detector housing, and a buzzer is fixedly connected in front of the combustible gas detector housing and below the alarm lights.

[0010] By adopting the above technical scheme, the combustible gas detector housing is fixed on one side of the wall behind the gas stove. When the gas stove is in use, a large amount of oil smoke will be generated. The arc filter element mesh plate can filter multiple first suction pipes to prevent the oil smoke from entering the first suction pipe. When a certain amount of oil smoke is generated at the corresponding positions of the arc filter element mesh plate and the first suction pipe, the rotating cap is rotated, and the rotating cap drives the rotating rod to rotate the fan-shaped collar block. The fan-shaped collar block rotates on the outer wall of the supporting screw. At the same time, the fan-shaped collar block drives the arc frame plate to rotate the arc filter element mesh plate. In this way, the arc filter element mesh plate can slide on the lower surface of the first suction pipe, thereby switching the filtering position between other hole positions of the arc filter element mesh plate and the first suction pipe. After switching, the locking nut and the supporting screw are rotated and squeezed at the left position of the fan-shaped collar block under the action of the thread. The arc filter element mesh plate can play a fixing role at the position below the first suction pipe, which is convenient for switching different positions of the arc filter element mesh plate to filter the oil smoke for the first suction pipe.

[0012] By adopting the above technical solution, multiple first suction pipes can inhale the air around the gas stove. The air enters the collecting pipe along the first suction pipe, and the air enters the second suction pipe along the connecting collecting pipe. Through the combustible gas sensor contact sensor inside the second suction pipe, the combustible gas sensor can know whether there is a combustible gas leakage, and the air after detection can be discharged along the exhaust pipe.

[0013] Technical effects and advantages of the utility model:

[0014] By setting a protective component, the arc filter element mesh plate can filter multiple first suction pipes to prevent oil smoke from entering the first suction pipe. When a certain amount of oil smoke is generated at the corresponding positions of the arc filter element mesh plate and the first suction pipe, the rotating rod rotates the fan-shaped collar block, and the fan-shaped collar block rotates on the outer wall of the supporting screw to switch the filtering position between other hole positions of the arc filter element mesh plate and the first suction pipe, thereby preventing the combustible gas detector from inhaling too much air oil smoke, and greatly extending the service life of the household combustible gas detector.

[0015] The multiple first suction pipes can inhale the air around the gas stove, the combustible gas sensor can know whether there is a combustible gas leak, and the detected air can be discharged along the external exhaust pipe, so that multi-point detection of the gas stove can be achieved, and the detection range is wider.
