Technical Field

[0001] The present application relates to the technical field of gas detectors, and specifically to a gas detection device. Background Art

[0002] A gas detector is an instrument tool for detecting gas leakage concentration, which mainly uses gas sensors to detect the types of gases in the environment;

[0003] There are many types of gas detectors, including: portable gas detectors, handheld gas detectors, fixed gas detectors, online gas detectors, etc. Among them, portable gas detectors are usually composed of a gas detector body, a display screen, a gas sensing port, a filter, a power button, etc.

[0004] However, the existing gas detector is provided with a gas sensing port at the top, and a filter is installed in the gas sensing port to filter the particles in the gas. When the gas detector is used for a long time, a lot of dust will accumulate on the filter, which will hinder the gas from entering, thus causing the detection data of the gas detector to be inaccurate. Therefore, it is necessary to design a gas detection device to solve the above problem.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

Wherein: the filter screen is suitable for buckling with the buckle block through the buckle hole, so as to be suitable for fixing the filter screen in the gas sensing port.

[0008] Furthermore, a dustproof structure is installed on the gas detector, and the dustproof structure includes: a hinge, which is installed on the gas detector, and the hinge has a rotating part, and a cover is connected to one end of the rotating part away from the gas detector.

[0009] Furthermore, a sealing gasket is provided at the contact position between the cover plate and the filter screen.

[0010] Furthermore, two groups of handles are installed on the filter screen, and a through groove matching the size of the handles is opened on the cover plate.

[0011] Furthermore, the buckle block has a limiting portion, and the limiting portion extends into the spring.

[0012] The beneficial effect of the present application is that a gas detection device provided by the present application, through the coordinated use of a gas sensing port, a perforation, a spring, a buckle block, a filter screen and a handle, makes it easy to disassemble and replace the filter screen, so as to increase the gas detection accuracy of the gas detector.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] like Figure 1-Figure 2 As shown, a gas detection device in the present application includes a gas detector 1, on which a power button 2 is installed, the power button 2 is used to control the opening and closing of the gas detector 1, and a display screen 3 is fixedly installed on the gas detector 1, the display screen 3 is used to display the gas detection value;

[0023] When the gas detector 1 is in use, by pressing the power button 2, the gas detector 1 starts working, and digital indications appear on the display screen in sequence. After preheating, the instrument enters the detection state. Then the gas detector 1 is placed in the environment to be detected. When there is a leak of the gas to be detected, the value displayed on the display 3 changes. The larger the displayed value, the greater the gas concentration.

[0024] like Figure 2-Figure 3 As shown, a gas sensing port 101 is provided on the gas detector 1, and three groups of through holes 102 are opened on both sides of the inner wall of the gas sensing port 101, a spring 103 is fixedly installed inside the through hole 102, and a buckle block 104 is fixedly installed at one end of the spring 103, and the buckle block 104 has a limiting portion, which extends into the spring 103, and the limiting portion is used to limit the spring 103 so that it can be linearly extended;

[0025] A mounting structure 4 is engaged in the gas sensing port 101, and the mounting structure 4 includes a filter screen 401 engaged in the gas sensing port 101, and a buckle hole (not shown in the figure) adapted to the buckle block 104 is opened on the filter screen 401, and the filter screen 401 is buckled with the buckle block 104 through the buckle hole, so as to be suitable for fixing the filter screen 401 in the gas sensing port 101;

[0026] A dustproof structure 5 is fixedly mounted on the gas detector 1, and the dustproof structure 5 includes a cover plate 501 hinged on the gas detector 1, and the cover plate 501 can be rotatably pressed on the filter screen 401;

[0027] In the present application, sealing gaskets are provided around the contact positions of the cover plate 501 and the filter screen 401 to increase the sealing performance between the cover plate 501 and the filter screen 401 .

[0028] Two sets of handles 402 are fixedly installed on the filter 401. The handles 402 are used to pull the filter 401 out of the gas sensing port 101 so as to clean the filter 401. At the same time, a through groove 502 matching the size of the handle 402 is opened on the cover 501. The through groove 502 is suitable for being sleeved on the handle 402 so that the cover 501 can fit on the filter 401.

[0029] When the gas detector 1 is in use, the cover plate 501 can be rotated to open the side of the gas detector 1, and then the handle 402 can be held and lifted to pull the filter 401 out of the gas sensing port 101 and clean it. When installing it again, first align one end of the filter 401 with one end of the inner wall of the gas sensing port 101, and squeeze the buckle block 104. The buckle block 104 squeezes the spring 103. When one end of the filter 401 fits with one end of the inner wall of the gas sensing port 101, the other end of the filter 401 is fit with the other end of the inner wall of the gas sensing port 101. When both ends of the filter 401 are completely fit with both ends of the inner wall of the gas sensing port 101, the buckle block 104 is buckled in the buckle hole through the action of the spring 103.

[0030] At the same time, after the gas detector 1 is used, the cover plate 501 can be rotated and attached to the surface of the filter 401 to prevent the filter 401 from dust when the gas detector 1 is not in use.

[0031] In summary, through the coordinated use of the gas sensing port 101, the perforation 102, the spring 103, the buckle block 104, the filter 401 and the handle 402, the filter 401 can be easily disassembled and replaced to increase the gas detection accuracy of the gas detector 1.
