Description

Technical Field

[0001] This utility model belongs to the field of gas alarms and relates to a household gas detection and alarm device with a suction function. Background Technology

[0002] Application document CN217426246U discloses a household combustible gas alarm based on the Internet of Things (IoT). The technical solution includes a support structure and an alarm structure. The support structure includes a housing and a cover, with the cover mounted on the housing. The alarm structure includes a support member, a combustible gas alarm body, a fan, and a hollow tube. The technical principle is to use the fan to accelerate airflow in order to detect indoor gas more quickly.

[0003] The technical solution in the aforementioned application document accelerates the airflow indoors while keeping the indoor gas content unchanged. However, the indoor air can be exhausted to the outside using the fan in the technical solution, thereby reducing the indoor gas content or inhibiting the increase of the gas content. Therefore, there is room for improvement in the aforementioned technical solution. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a household gas detection and alarm device with a suction function.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a household gas detection and alarm device with a suction function, comprising a gas detector and a control box. The gas detector includes an inlet pipe. The control box contains a PCB circuit board and a speaker. One end of the inlet pipe is connected to a fan, and the other end is connected to a telescopic exhaust pipe. The end of the telescopic exhaust pipe away from the gas detector is connected to an externally threaded pipe. The end of the externally threaded pipe away from the gas detector is connected to an internal pressure plate for pressing against the inside of the glass. The externally threaded pipe is threadedly connected to an internally threaded pipe. The internally threaded pipe is connected to an external pressure plate for pressing against the outside of the glass. The end of the internally threaded pipe away from the gas detector has an internal protrusion. A filter screen is provided between the internal protrusion and the externally threaded pipe.

[0006] Preferably, the end of the external pressure plate furthest from the gas detector is connected to a pressure plate.

[0007] Preferably, the end of the air intake pipe away from the fan is connected to a mounting plate.

[0008] Preferably, the mounting plate is connected to a bracket, the bracket including a side for adhesive to the window frame.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention uses a fan to draw indoor air for the gas detector, thus accelerating indoor airflow and enabling the gas detector to detect gas leaking into the room more quickly, which helps to quickly detect abnormalities.

[0010] During installation, this utility model makes an opening in the window glass so that after the inner threaded tube and the outer threaded tube are screwed together, the inner pressure plate and the outer pressure plate are pressed tightly against both sides of the glass to achieve positioning, and the detected indoor air is discharged to the outside, reducing the risk caused by high indoor gas content.

[0011] This invention positions the gas detector by attaching a bracket to the window frame and includes a telescopic exhaust pipe, making installation more convenient and faster. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] like Figures 1-4 As shown, a household gas detection and alarm device with suction function includes a gas detector 1 and a control box 2. The gas detector 1 is used to detect gas in indoor air and includes an air inlet pipe 3. The control box 2 is equipped with a PCB circuit board and a speaker. The PCB circuit board is equipped with a communication module for information interaction with a mobile terminal or cloud. When the gas detector 1 detects that the gas content exceeds the standard, the PCB circuit board controls the speaker to start and issue an alarm. The mobile terminal or cloud can also control other Internet of Things devices (such as range hoods) to start and exhaust indoor air. This is the prior art, and this utility model will not be described in detail here.

[0018] To expel the detected air from the room and reduce or suppress the indoor gas content while detecting it, one end of the air inlet pipe 3 is connected to a fan 4, which draws indoor air into the air inlet pipe 3. The other end is connected to a telescopic exhaust pipe 5, which can be extended / retracted like the exhaust pipe of a range hood for easy adjustment. The end of the telescopic exhaust pipe 5 away from the gas detector 1 is connected to an external threaded pipe. The end of the external threaded pipe away from the gas detector 1 is connected to an inner pressure plate 6 for pressing against the inside of the glass. The diameter of the inner pressure plate 6 is larger than that of the external threaded pipe. The external threaded pipe is threaded to an internal threaded pipe 7. The internal threaded pipe 7 is connected to an external pressure plate 8 for pressing against the outside of the glass. The external pressure plate 8 is larger than that of the internal threaded pipe 7. The end of the internal threaded pipe 7 away from the gas detector 1 is provided with an inner protrusion 9. A filter screen 10 is provided between the inner protrusion 9 and the external threaded pipe to prevent feathers, birds, etc. from entering the external threaded pipe.

[0019] The invention is used as follows: An opening is made in the glass window beforehand. A circular filter is placed inside the internally threaded tube 7. The internally threaded tube 7 is placed outdoors, and the externally threaded tube is placed indoors. Then, the glass window is threaded together through the opening. The diameters of the inner pressure plate 6 and the outer pressure plate 8 are larger than the opening of the glass window. When tightened, the inner pressure plate 6 and the outer pressure plate 8 press against the glass to achieve positioning. The fan 4 draws indoor air and sends it into the air intake pipe 3 for the gas detector 1 to detect. After the detection is completed, the air is discharged to the outside through the telescopic exhaust pipe 5, the externally threaded tube, and the filter 10.

[0020] Furthermore, an extension plate 11 is connected to the end of the external pressure plate 8 that is away from the gas detector 1. The extension plate 11 is perpendicular to the external pressure plate 8, making it easier to screw the internal threaded pipe 7.

[0021] Furthermore, the end of the intake pipe 3 furthest from the fan 4 is connected to a mounting plate 12.

[0022] Furthermore, the mounting plate 12 is connected to a bracket 13, which includes a side 15 for bonding to the window frame 14.

[0023] Specifically, since the length and direction of the telescopic exhaust pipe 5 can be adjusted to a limited extent, the bracket 13 can be fixed to the windowsill or window frame 14. Generally, installation requires drilling. Therefore, this utility model provides an embodiment: the bracket 13 is glued to the window frame 14 with strong adhesives such as AB glue.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
