However, existing home combustible gas detectors often only perform simple sensing operations and cannot react accordingly based on the sensing results. Utility Model Content

[0007] The combustible gas detection structure includes an external sealed housing, a second combustible gas detector is installed inside the external sealed housing, and exhaust fans are installed at both ends of the external sealed housing.

[0008] Furthermore, the air inlet is equipped with a first filter structure, and the exhaust pipe is equipped with a one-way valve structure to facilitate the filtration of impurities and prevent gas backflow.

[0009] Furthermore, the outer sealing housing is provided with air collection pipes at both ends to cooperate with the exhaust fan, and the air collection pipes are equipped with electrically controlled valves to facilitate daily maintenance of the sealing of the inner part of the outer sealing housing.

[0010] Furthermore, the combustible gas detection structure has a ring-shaped cylinder at the bottom that surrounds the first combustible gas detector, and a second filter structure at the bottom of the cylinder for daily protection of the first combustible gas detector.

[0011] Furthermore, the controller is equipped with a buzzer and a warning light on both sides, which can perform buzzer and warning light operation.

[0012] The advantages of this household combustible gas detector compared to existing technologies are as follows: By adding a sealed combustible gas detector and an exhaust structure to the traditional combustible gas detector, the accuracy of detection can be guaranteed, and the exhaust operation can be carried out in a timely manner after detection.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-3 A household combustible gas detector includes a fixed mounting bracket 1. A controller 2 is located at the bottom of the mounting bracket 1. The controller 2 handles basic control modules and also includes a remote signal transmission module for remote signal transmission. This is common existing technology and will not be elaborated further. A combustible gas detection structure 3 is located at the bottom of the controller 2. A first combustible gas detector 4 is located at the bottom of the combustible gas detection structure 3. A cylinder 11, which annularly surrounds the first combustible gas detector 4, is located at the bottom of the combustible gas detection structure 3. A second filter structure 12 is located at the bottom of the cylinder 11. The second filter structure 12 ensures gas entry while preventing the filtering of foreign objects or insects from affecting the sensor's detection accuracy. The first combustible gas detector 4 is turned on daily for routine combustible gas detection.

[0019] The combustible gas detection structure 3 includes an outer sealed housing 13, inside which a second combustible gas detector 14 is installed. Exhaust fans 15 are installed at both ends of the outer sealed housing 13, and in practice, the exhaust fans 15 draw air to the same side to ensure gas flow in the same direction. Air collection pipes 16 are installed at both ends of the outer sealed housing 13 to cooperate with the exhaust fans 15. An electrically controlled valve 17 is installed on the air collection pipe 16. The first combustible gas detector 4 is used for routine detection. When the first combustible gas detector 4 detects combustible gas, to ensure detection accuracy and prevent gas leakage, the exhaust fans 15 and the electrically controlled valve 17 are activated to ensure that external gas quickly enters the outer sealed housing 13 for secondary detection by the second combustible gas detector 14. If a certain concentration of combustible gas is still detected, it indicates that a combustible gas leak has occurred.

[0020] The fixed mounting bracket 1 is equipped with a gas collection hood 5 on its top. The fixed mounting bracket 1 is equipped with an air inlet 6 that communicates with the inside of the gas collection hood 5. The gas collection hood 5 is equipped with an exhaust fan 7. The top of the gas collection hood 5 is equipped with an exhaust duct 8 that extends to the outside. The air inlet 6 is equipped with a first filter structure 10. The exhaust duct 8 is equipped with a one-way valve structure 9. If a combustible gas leak occurs, the combustible gas in the room can be quickly discharged from the room through the gas collection hood 5 and the exhaust duct 8 by activating the exhaust fan 7, thereby reducing the concentration of combustible gas in the room and preventing accidents.

[0021] The controller 2 is equipped with a buzzer 18 and a warning light 19 on both sides. When a certain concentration of combustible gas is detected, the buzzer 18 and the warning light 19 are activated simultaneously to issue an alarm for indoor operations.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
