[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] like Figure 1 As shown, the utility model provides a gas detector that is easy to read the results, including a shell 1, and a control mainboard 2 is arranged inside the shell 1. The control mainboard 2 is responsible for processing various data and control instructions to ensure that the instrument can work normally. In addition, the shell 1 includes an upper shell 11 and a lower shell 12 that is connected to the upper shell 11, which not only facilitates the assembly and disassembly of the gas detector, but also can effectively protect the internal components to prevent damage caused by external impact or collision. The upper shell 11 and the lower shell 12 are connected by a precise cover to form a solid protective layer, which firmly wraps the key components such as the control mainboard 2 to ensure that it can work in a safe and stable environment.

[0034] like Figures 2 to 4 As shown, in this embodiment, a plurality of first connecting columns 111 are provided on the inner side of the upper shell 11, and a plurality of second connecting columns 121 corresponding to each other are provided on the inner side of the lower shell 12. The shell connector (not shown in the figure) passes through the second connecting column 121 and is connected to the first connecting column 111, that is, the shell connector tightly connects the upper shell 11 and the lower shell 12 together. This connection method is not only simple and fast, but also very firm, and can effectively prevent the gas detector from loosening or falling off during use. In addition, a first limiting portion 116 is provided on the edge of the upper shell 11, and a second limiting portion 123 is provided on the edge of the lower shell 12. After the upper shell 11 and the lower shell 12 are covered and connected, the first limiting portion 116 and the second limiting portion 123 abut against each other to form an additional fixing point, which not only further enhances the stability of the shell 1, but also makes the assembly of the shell 1 more precise and reliable.

[0035] like Figure 2 , Figure 6As shown, in this embodiment, a plurality of gas detection sensors 3 are arranged inside the housing 1, and the plurality of gas detection sensors 3 are connected to the control main board 2, so as to detect different gases. Specifically, four gas detection sensors 3 can be designed to detect combustible gas, hydrogen sulfide gas, carbon monoxide and oxygen respectively. Once the gas detection sensor 3 detects that the corresponding gas concentration in the working environment reaches or exceeds the set critical point, the gas detector will immediately activate the built-in alarm system. Of course, six gas detection sensors 3 can also be designed. In actual design, the number of gas detection sensors 3 and the type of gas to be detected can be designed according to actual needs.

[0036] It should be noted that when the gas detection sensor 3 detects that the corresponding gas concentration in the working environment reaches or exceeds the set critical point, the gas detector will immediately activate the built-in alarm system. This is the existing technology, and the utility model also makes improvements to this part, so its structure and principle will not be described in detail.

[0037] like Figure 1 , Figure 2 , Figure 5 As shown, in this embodiment, a display surface 112 is provided at the end of the housing 1, the display surface 112 is provided on the upper shell 11, and the display surface 112 is inclined with respect to the main part of the housing 1, and a display module 4 is provided on the display surface 112, and the display module 4 is connected to the control main board 2, and the display module 4 can receive and display the gas concentration data detected by the gas detection sensor 3 in real time. Since the display surface 112 is inclined with respect to the main part of the housing 1, the display content of the display module 4 provided on the display surface 112 can be more easily observed by the user in some occasions where the line of sight is limited or the space is narrow, which not only reduces the difficulty of observation caused by the viewing angle problem, but also facilitates the user to clearly read the detection results at different angles.

[0038] In this embodiment, the inclination angle of the display surface 112 relative to the main part of the shell 1 is 40°~60°, and the inclination angle of the display surface 112 relative to the main part of the shell 1 can be designed to be 44°. Of course, in actual design, the size of the inclination angle of the display surface 112 relative to the main part of the shell 1 can be designed according to actual needs. In addition, in other optional embodiments, the display surface 112 can also be designed to be connected to the main part of the shell 1 through a rotating component, so that the inclination angle of the display surface 112 relative to the main part of the shell 1 is adjustable, so that the user can adjust the inclination angle of the display surface 112 by rotating the component according to their own needs to obtain the best observation effect and improve the applicability of the gas detector.

[0039] like Figure 2As shown, in this embodiment, the display module 4 includes a display circuit board 41 and a display screen 42. The display circuit board 41 is connected to the control main board 2. A close connection is established between the display circuit board 41 and the control main board 2 to ensure accurate transmission of information, so that the control main board 2 can pass the detected gas concentration data to the display circuit board 41, so as to perform subsequent display processing. In addition, the display screen 42 is arranged on the top of the display circuit board 41, and the display screen 42 presents the processed gas concentration data to the user in a visual form. The display screen 42 is closely connected to the display circuit board 41, and the display content can be updated in real time through the control of the display circuit board 41. At the same time, in order to ensure that the user can clearly observe the display content, the display screen 42 is designed to be parallel to the display surface 112, so that the display content on the display screen 42 can be more clearly observed by the user.

[0040] like Figure 2 , Figure 3 As shown, in this embodiment, the display module 4 also includes a PC protective lens 43 disposed on the top of the display screen 42, and a mounting groove 113 is disposed on the display surface 112. The PC protective lens 43 is disposed in the mounting groove 113, which effectively prevents the display screen 42 from being hit and scratched by external objects, and does not affect the clarity of the user's observation of the screen content. In addition, the PC protective lens 43 is placed in the mounting groove 113 so that it is tightly combined with the display surface 112, which not only ensures the stability of the PC protective lens 43, but also makes the entire display module 4 look neater and more beautiful.

[0041] like Figure 2 , Figure 4 As shown, in this embodiment, a circuit board placement groove 122 is provided inside the lower shell 12, and the bottom of the display circuit board 41 is provided on the circuit board placement groove 122, ensuring that the display circuit board 41 can be firmly fixed in the lower shell 12, and is not easy to shake or shift. Moreover, through the design of the circuit board placement groove 122, not only the display circuit board 41 is effectively supported and protected, but also the installation process of the entire display circuit board 41 becomes simpler and more efficient. In addition, a pad 44 is provided on the side of the display circuit board 41 away from the display screen 42, and the pad 44 is parallel to the display surface 112. The pad 44 not only provides additional support for the display circuit board 41, so that it is more firmly installed on the circuit board placement groove 122 of the lower shell 12, but also ensures the parallel relationship between the display circuit board 41 and the display surface 112, so that the user can clearly observe the display content, and makes the entire display module 4 look more beautiful and coordinated, ensuring that the display screen 42 can accurately and clearly display the detection results of the gas concentration.

[0042] like Figure 1 , Figure 2As shown, in this embodiment, a button installation slot 114 and a switch button slot 115 are provided on the upper shell 11, a direction adjustment button 5 is provided in the button installation slot 114, a switch button 6 is provided in the switch button slot 115, and the direction adjustment button 5 is connected to the control main board 2, then the user can adjust the direction of the display content on the display module 4 by pressing this button, ensuring that the user can always easily read the test results, so that the user can easily read the test results at different angles or different usage scenarios, greatly improving the user experience. The switch button 6 is connected to the control main board 2 to realize the opening or closing of the gas detector. In addition, a connector can be provided on the control main board 2, and the direction adjustment button 5 and the switch button 6 are both connected to the control main board 2 through the connector to ensure the stability of the buttons.

[0043] It should be noted that adjusting the direction of the display content on the display module 4 through the direction adjustment button 5 and turning the gas detector on or off through the switch button 6 are both existing technologies, and the present utility model does not make any improvements to this part, so its structure and principle will not be described in detail.
