Description

Technical Field

[0001] This utility model relates to the field of combustible gas detection technology, and in particular to a low-power wireless combustible gas detector. Background Technology

[0002] Low-power wireless combustible gas detectors are devices used to monitor the concentration of combustible gases in the environment. They are characterized by low power consumption and wireless communication capabilities. These detectors are commonly used in industrial, commercial, and residential settings to provide early detection and alarms for combustible gas leaks. There are two types of combustible gas detectors: catalytic and infrared optical. Catalytic combustible gas detectors use the change in resistance of a heated refractory platinum wire to determine the concentration of combustible gas. When combustible gas enters the detector, it causes an oxidation reaction (flameless combustion) on the surface of the platinum wire. The heat generated raises the temperature of the platinum wire, and the resistivity of the platinum wire changes. Infrared optical detectors use an infrared sensor to detect alkane combustible gases in the environment through the absorption principle of an infrared light source.

[0003] In existing technologies, detectors are usually fixed to walls or other locations with screws during installation. This is not only troublesome to disassemble but also damages the walls. In addition, some detectors are connected to a plug and are directly plugged into the socket when powered on, but they lack fixing components. Over time, the plug may loosen, causing the detector to lose power and thus affecting the detection results. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a low-power wireless combustible gas detector, which aims to improve the problem that detectors are usually fixed to the wall or other locations with screws during installation. This is not only troublesome to disassemble but also causes damage to the wall. At the same time, some detectors are connected to a plug and are directly plugged into the socket when powered on, but they lack a fixing component. After a long time, the plug will loosen, causing the detector to lose power and thus affecting the detection results.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A low-power wireless combustible gas detector includes a detector body. One side of the detector body is uniformly and fixedly connected to one end of several fixed brackets. The other end of the fixed brackets is fixedly connected to a suction cup base. The top of the suction cup base is fixedly connected to a connecting sleeve. A connecting rod is slidably connected inside the connecting sleeve. Sliding grooves are formed through both sides of the connecting sleeve. A sliding rod that matches the sliding groove is fixedly connected inside the connecting rod. A handle is rotatably connected to both ends of the sliding rod. A suction cup body is fixedly connected to the bottom end of the connecting rod. The suction cup body is located below the suction cup base.

[0007] Preferably, a plurality of heat dissipation holes are uniformly and symmetrically formed on one side of the detector body.

[0008] Preferably, the detector body is provided with an infrared sensor, and a baffle is provided on the outside of the infrared sensor, which is fixedly connected to one side of the detector body.

[0009] Preferably, a groove is provided on the other side of the detector body, and buckles are symmetrically fixedly connected to both sides of the inner wall of the groove.

[0010] Preferably, support plates are symmetrically fixedly connected to both sides of the groove, and a slot is provided on the top of the support plate, with a locking block symmetrically fixedly connected to the inner side of the slot.

[0011] Preferably, a matching fixing rod is slidably connected in the slot, one end of the fixing rod is threadedly connected to a fixing ring, the other end of the fixing ring is fixedly connected to a plug, and one side of the plug is fixedly connected to a power cord.

[0012] Preferably, a plurality of indicator lights are evenly provided on one side of the detector body, and the indicator lights are located below the infrared sensor.

[0013] Preferably, a nameplate is fixedly connected to one side of the detector body.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by inserting the fixing rods on both sides of the plug into the slots at the top of the support plate, and using the elastic and deformable locking blocks to limit and fix the fixing rods, and then fixing the fixing rods with fixing rings, the plug can be fixed to the back of the detector body. It can be directly connected to the socket, or the plug can be disassembled according to the installation position, and the power cord that is surrounded in the groove and limited by the buckle can be pulled out to change the distance between the detector body and the plug.

[0016] 2. In this utility model, the detector can be fixed to the wall surface without damaging the wall by means of multiple suction cups on the rear side of the detector body. By pressing the handle, the sliding rod inside the connecting rod moves in the sliding grooves on both sides of the connecting sleeve, thereby moving the connecting rod inside the connecting sleeve, which squeezes the suction cup body at the bottom of the connecting rod, squeezes out the air inside, and then adsorbs it onto the wall, thus fixing the detector. At the same time, the detector can be removed by simply turning the handle upwards. The operation is simple. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1-Figure 3 One embodiment provided by this utility model:

[0024] A low-power wireless combustible gas detector includes a detector body 1. Several fixing brackets 16 are uniformly fixedly connected to one end of one side of the detector body 1. A suction cup seat 7 is fixedly connected to the other end of the fixing bracket 16. A connecting sleeve 17 is fixedly connected to the top of the suction cup seat 7. A connecting rod 20 is slidably connected inside the connecting sleeve 17. Slide grooves 18 are provided through both sides of the connecting sleeve 17. A slide rod 19 that matches the slide groove 18 is fixedly connected inside the connecting rod 20. A handle 22 is rotatably connected to both ends of the slide rod 19. A suction cup body 11 is fixedly connected to the bottom end of the connecting rod 20. The suction cup body 11 is located below the suction cup seat 7. By pressing the handle 22, the slide rod 19 inside the connecting rod 20 moves within the slide grooves 18 on both sides of the connecting sleeve 17, thereby moving the connecting rod 20 within the connecting sleeve 17. This squeezes the suction cup body 11 at the bottom of the connecting rod 20, expelling the air inside and adhering it to the wall.

[0025] Referring to 1, a number of heat dissipation holes 2 are evenly and symmetrically opened on one side of the detector body 1. The heat dissipation holes 2 are used to dissipate heat from the detector body 1 and control its internal temperature. An infrared sensor 4 is installed inside the detector body 1. The infrared sensor 4 is used to detect combustible gas. A baffle 3 is provided on the outside of the infrared sensor 4. The baffle 3 is fixedly connected to one side of the detector body 1. A number of indicator lights 6 are evenly arranged on one side of the detector body 1. The indicator lights 6 are located below the infrared sensor 4. A nameplate 5 is fixedly connected to one side of the detector body 1. The nameplate 5 is used to register detector information.

[0026] Reference Figure 2 On the other side of the detector body 1, a groove 8 is provided. Buckles 10 are symmetrically fixedly connected to both sides of the inner wall of the groove 8. Support plates 12 are symmetrically fixedly connected to both sides of the groove 8. A slot 23 is provided on the top of the support plate 12. A locking block 15 is symmetrically fixedly connected to the inner side of the slot 23. The locking block 15 is made of an elastic material capable of deformation. A matching fixing rod 13 is slidably connected within the slot 23. A fixing ring 14 is threaded to one end of the fixing rod 13, and a plug 21 is fixedly connected to the other end of the fixing ring 14. A power cord 9 is fixedly connected to one side of the plug 21. The fixing rods 13 on both sides of the plug 21 are inserted into the slots 23 at the top of the support plate 12, and the fixing rods 13 are fixed in place by the locking block 15. The fixing rods 13 are then fixed by tightening the fixing ring 14. The plug 21 can be fixed at the rear of the detector body 1. It can be directly connected to the socket, or the plug 21 can be disassembled according to the installation position. The plug 21 can be moved by stretching the power cord 9. When the power cord 9 does not need to be stretched, it is limited by the buckle 10 and coiled in the groove 8.

[0027] Working principle: Depending on the distance between the socket and the required installation position of the detector body 1, choose whether to disassemble or fix the plug 21. If fixing, simply insert the fixing rods 13 on both sides of the plug 21 into the slots 23 at the top of the support plate 12, and use the locking block 15 to limit and fix the fixing rods 13. Then, fix the fixing rods 13 by tightening the fixing ring 14. The plug 21 can then be fixed behind the detector body 1. Then, press the throttle 22 to drive the slide rod 19 in the connecting rod 20 to move in the slide grooves 18 on both sides of the connecting sleeve 17, thereby moving the connecting rod 20 in the connecting sleeve 17. This squeezes the suction cup body 11 at the bottom of the connecting rod 20, expelling the air inside and adhering it to the wall.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
