The signals generated by the sensors are weak electrical signals or other forms of signals. These signals need to be converted into digital signals or other forms of readable signals for further processing and analysis. The processed data will be displayed on the display screen of the device for users to monitor in real time;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1-4, an embodiment provided by the present utility model: a waterproof and moisture-proof gas detection device, including two circulation fans 1. The circulation fans can provide power to make the air flow. The two circulation fans 1 are fixedly connected to a box body 4. The box body 4 can be used to place other components. The bottoms of the two circulation fans 1 are both fixedly connected to air boxes 2. Air inlets 3 are opened on the bottom sides of the two air boxes 2. The two air boxes 2 are fixedly connected to circulation air ducts 5 on their far sides. The air box 2 intakes air through the air inlet 3 and discharges air through the circulation air duct 5. The two circulation air ducts 5 are fixedly connected to the inside of the box body 4 on their far sides. A plurality of uniformly distributed air outlets 6 are fixedly connected to the inner sides of the bottoms of the two circulation air ducts 5. The air in the circulation air duct 5 can be blown out through the air outlets 6. Infrared radiation lamp frames 7 are fixedly connected to the left and right sides inside the box body 4. A plurality of uniformly distributed mid-infrared radiation lamps 8 are fixedly connected to the opposite sides of the two mid-infrared radiation lamp frames 7. The mid-infrared radiation lamp frame 7 can be used to connect and fix the mid-infrared radiation lamp 8. A filter plate 10 is slidably connected to the top of the box body 4. The filter plate 10 can filter the air blown out by the air outlets 6 to prevent dust from affecting the heating effect. A disassembly component is arranged on the right side of the filter plate 10.

[0034] Refer to Figures 4-5 , the disassembly component includes a pull rod 16. A connecting shell 15 is slidably connected to the outer periphery of the pull rod 16. The connecting shell 15 plays a role in connecting and fixing. A spring 17 is sleeved on the outer periphery of the pull rod 16. A stop piece 18 is fixedly connected to the left side of the spring 17. The movement of the pull rod 16 will drive the movement of the stop piece 18. The movement of the stop piece 18 will squeeze the spring 17 to generate pressure. The stop piece 18 is slidably connected to the inside of the connecting shell 15. The left end of the pull rod 16 is slidably connected to the right side of the filter plate 10. A chute 19 is opened on the right side of the filter plate 10. The pull rod 16 slides in the chute 19.

[0035] Refer to Figures 2-5 , a detection tube 13 is fixedly connected to the bottom side of the box body 4. A gas sensor 11 is fixedly connected to the inside of the detection tube 13. An alarm device 12 is fixedly connected to the top of the rear side of the box body 4. After the gas enters the detection tube 13, the gas sensor 11 can transmit the detected gas concentration data to the alarm device 12. A bracket 9 is fixedly connected to the bottom end of the circulation air duct 5. The bracket 9 can be used to fix the circulation air duct 5. The bottom end of the bracket 9 is fixedly connected to the bottom side of the box body 4. Empty slots are opened on the far sides of the two mid-infrared radiation lamp frames 7. The empty slots can enable the circulation air duct 5 to pass through the mid-infrared radiation lamp frame 7. Two baffle plates 14 are slidably connected to the bottom left side of the filter plate 10. The two baffle plates 14 are both fixedly connected to the inside of the box body 4. The baffle plates 14 can prevent one side of the filter plate 10 from slipping. A pull block 20 is fixedly connected to the right end of the pull rod 16. The pull block 20 can facilitate the pulling out of the pull rod 16.

[0036] Working principle: When the gas enters the detection tube 13, the gas sensor 11 will detect the concentration of the gas, and then transmit the detected gas concentration data to the alarm device 12. The alarm device 12 will display the data. When the data exceeds the normal range, the alarm device 12 will give an alarm reminder. When it is necessary to dry the gas detection device, the mid-infrared radiation lamp 8 can be turned on. After the mid-infrared radiation lamp 8 is turned on, it will heat up. Then, by starting the circulation fan 1 to drive the air flow, the air will enter the circulation air duct 5. When the air reaches the air outlet 6 in the circulation air duct 5, it will be blown out from the air outlet 6. The air blown out from the air outlet 6 will pass through the filter plate 10 for filtration. The filtered air will be heated by the mid-infrared radiation lamp 8, and then the heated hot air will pass through the box body from bottom to top, and then be sucked into the air box 2 by the circulation air duct 5 from the air inlet 3. When the hot air enters the air box 2, it will be blown out again by the circulation fan 1 and enter the circulation air duct 5 for reheating circulation, so as to achieve the effect of circulating heating and drying. When it is necessary to disassemble the filter plate 10, the pull block 20 can be pulled to drive the pull rod 16 to move. The movement of the pull rod 16 drives the movement of the retaining piece 18. The movement of the retaining piece 18 will squeeze the spring 17. When the spring 17 is squeezed, it will squeeze the connecting shell 15 to generate an elastic force. When the pull rod 16 slides out of the chute 19 of the filter plate 10, the filter plate 10 can be removed. At this time, the pull block 20 is released, and the elastic force generated by the spring 17 will drive the movement of the retaining piece 18. The movement of the retaining piece 18 will drive the movement of the pull rod 16, and the pull rod 16 will return to its initial position. During installation, the pull block 20 is pulled to drive the pull rod 16 to move. The movement of the pull rod 16 drives the movement of the retaining piece 18. The movement of the retaining piece 18 will also squeeze the spring 17. When the spring 17 is squeezed, it will squeeze the connecting shell 15 to generate an elastic force. After the filter plate 10 is placed, the pull block 20 can be released, and the pull rod 19 will slide into the chute 19 under the action of the elastic force to fix the filter plate 10 and complete the disassembly.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
