Description

Technical Field

[0001] This utility model relates to the field of combustible gas detection technology, specifically a household combustible gas detector. Background Technology

[0002] With the increasing prevalence of household gas use, explosions, fires, and poisoning accidents caused by natural gas and liquefied petroleum gas leaks are frequent, seriously threatening the safety of residents' lives and property.

[0003] Battery-powered home combustible gas detectors mainly consist of a gas sensor, signal processing circuit, audible and visual alarm module, wireless communication module, and high-performance battery module. The high-performance battery module uses low-power, long-life lithium or alkaline batteries to provide stable power to the detector's components. Some products also feature battery level monitoring to remind users to replace the batteries in a timely manner. The gas sensor typically uses catalytic combustion, semiconductor, or infrared sensors to detect the concentration of combustible gas in the environment. The signal processing circuit amplifies, filters, and performs analog-to-digital conversion on the weak signals output by the sensor. The audible and visual alarm module emits a high-decibel buzzer and flashing lights when a dangerous concentration is detected. The wireless communication module supports communication protocols such as Wi-Fi or Bluetooth, and can push alarm information to the user's mobile app.

[0004] However, the above-mentioned devices have obvious shortcomings in use. Most traditional detectors rely on natural diffusion for gas sampling, which is slow, has a small coverage area, and is slow to react to combustible gases in areas far from the detector. Especially in well-ventilated environments, this may lead to detection delays and failure to detect potential hazards in time. In view of this, we propose a household combustible gas detector.

[0031] Please see Figures 1-8 This utility model provides a technical solution:

[0032] A household combustible gas detector includes a connecting frame 1, with a mounting box 2 fixedly installed at the bottom of the connecting frame 1.

[0033] In one embodiment of this utility model, a detection component 3 is provided on the mounting box 2. The detection component 3 includes a battery compartment 31. The battery compartment 31 is fixedly installed inside the mounting box 2. A battery body 32 is snapped into the battery compartment 31. A sliding cover 33 is snapped into the mounting box 2. A sound groove 34 is provided on the mounting box 2. A power switch 35 is provided on the mounting box 2. An air inlet 36 is provided on the connecting frame 1. A detection device 37 is fixedly installed inside the mounting box 2. A buzzer 38 is fixedly installed inside the mounting box 2. A square connecting tube 310 is fixedly installed on the battery compartment 31. An installation tube 315 is fixedly installed above the connecting frame 1. An arc-shaped filter plate 39 is fixedly installed on the installation tube 315. An air extraction hole 311 is provided on the square connecting tube 310. A heat dissipation plate 312 is fixedly installed. A small exhaust device 313 is fixedly installed inside the mounting tube 315. A servo motor 314 is fixedly installed on the mounting tube 315. Multiple sets of air inlets 36 and exhaust ports 311 are provided. The heat dissipation plate 312 is located below the square connecting tube 310. The power switch 35 is electrically connected to the detection device 37. The battery body 32 is connected to the detection device 37 via a power cable. The detection device 37 is connected to the buzzer 38 via a power cable and a data cable. The buzzer 38 is located above the sound slot 34. The exhaust end of the small exhaust device 313 is located inside the square connecting tube 310. The exhaust end of the small exhaust device 313 is located inside the mounting tube 315. The output end of the servo motor 314 is connected to the small exhaust device 313.

[0034] In this embodiment, the battery body 32 inside the battery compartment 31 first provides power to the entire detection assembly 3. Simultaneously, the sliding cover 33 protects the battery compartment 31 and facilitates the replacement of the battery body 32. The power supply is controlled by a power switch 35. When the power switch 35 is turned on, the battery body 32 supplies power to the detection device 37 via a power cord, and the built-in catalytic combustion sensor in the detection device 37 begins operation. When the device is working, the servo motor 314 starts, driving the small exhaust device 313 to operate. The exhaust end of the small exhaust device 313 draws gas through multiple sets of exhaust holes 311 on the square connecting pipe 310. External gas enters through the air inlet 36 and exits through the arc-shaped filter plate 39. The staggered arrangement of multiple air inlets 36 and exhaust ports 311 creates a convection effect, expanding the gas sampling coverage. The extracted gas is filtered and then enters the detection device 37 for analysis. When the detection device 37 detects that the concentration of combustible gas has reached the lower explosive limit, it sends a signal to the buzzer 38 through the power line and data line. The buzzer 38 then sounds an alarm through the sound slot 34. At the same time, the heat dissipation plate 312 on the battery compartment 31 can reduce the temperature generated by the continuous operation of the battery body 32 inside the battery compartment 31, avoiding false alarms from the detection device 37 due to high temperature.

[0035] In one embodiment of this utility model, a mounting component 4 is provided on the connecting frame 1. The mounting component 4 includes a slide tube 41. The slide tube 41 is fixedly mounted on the connecting frame 1. A square groove 42 is opened on the slide tube 41. An mounting groove 43 is opened on the connecting frame 1. One end of an elastic block 44 is fixedly mounted on the connecting frame 1. A limiting ball 45 is fixedly mounted on the other end of the elastic block 44. A circular mounting plate 46 is fixedly mounted on the indoor ceiling. An mounting block 47 is fixedly mounted on the circular mounting plate 46. A limiting plate 48 is fixedly mounted on the mounting block 47. A limiting groove 49 is opened on the limiting plate 48. The square cross-section of the square groove 42 is the same size as the square cross-section of the limiting plate 48. The limiting ball 45 is made of rubber. The cross-section of the limiting ball 45 is the same size as the cross-section of the limiting groove 49. The positions of the limiting ball 45 and the limiting groove 49 are corresponding. The end of the limiting plate 48 away from the mounting block 47 is designed with rounded corners.

[0036] In this embodiment, during installation, the circular mounting plate 46 is first fixedly installed on the indoor ceiling. The slide tube 41 is aligned with the limiting plate 48 and can be easily inserted. As the connecting bracket 1 moves along the slide tube 41, the limiting plate 48 squeezes the limiting ball 45, causing it to contract. When the limiting ball 45 corresponds to the limiting groove 49, the elastic block 44 pushes the limiting ball 45 into the limiting groove 49, forming a mechanical lock, thus completing the rapid installation of the detector, which is more convenient than traditional screw installation.
