[0003] However, traditional designs often face a dilemma: while placing the sensor within a housing effectively protects it from external physical damage, it limits direct contact between the gas and the sensor, affecting detection accuracy and sensitivity. Conversely, if the sensor is directly exposed to the external environment, it is prone to bumps and collisions during transportation and storage, causing damage to the sensor and ultimately affecting the overall performance and lifespan of the device. Therefore, we have improved this by proposing a detection device based on a semiconductor gas sensor. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0026] Example 1, please refer to Figure 1 , a detection device based on a semiconductor gas sensor, comprising a protective shell 1, on which a semiconductor gas sensor body 2 is provided, a groove 5 is provided on one side of the protective shell 1 on which the semiconductor gas sensor body 2 is provided, and side grooves 501 connected to the groove 5 are provided on both sides of the protective shell 1, and a protective mounting plate 504 for protecting the semiconductor gas sensor body 2 is rotatably connected between the two side grooves 501 and the groove 5, and an elongated mounting hole 506 is provided on the protective mounting plate 504; this design has a significant protective effect. During transportation and storage, the detection device often experiences various unstable environments and handling operations. The presence of the rotating protective mounting plate 504 can form a solid physical barrier, which greatly reduces the risk of the semiconductor gas sensor body 2 being subjected to external impact, thereby reducing problems such as damage to internal components and line failures caused by bumps. This not only extends the service life of the sensor body, but also reduces the maintenance and replacement costs caused by equipment damage, ensures the long-term stable operation of the detection device, and saves users a lot of time and economic costs.

[0027] Further, such as Figure 1 As shown, the protective mounting plate 504 is arranged in an L shape, and the protective mounting plate 504 is plugged into the side groove 501 and the inner wall of the groove 5. The limiting of the protective mounting plate 504 by the side groove 501 and the inner wall of the groove 5 can improve the stability between the protective mounting plate 504 and the protective shell 1.

[0028] Further, such as Figure 3 As shown, a connecting shaft 502 is fixedly connected at the junction of the side groove 501 and the groove 5, and a vertical long hole 505 is opened on the protective mounting plate 504, and the vertical long hole 505 is plugged into the outer surface of the connecting shaft 502 (the connecting shaft 502 and the vertical long hole 505 can rotate relative to each other, and can also slide up and down relative to each other). The protective mounting plate 504 can be installed on the protective shell 1 through the connecting shaft 502 and the vertical long hole 505, and the rotation setting of the protective mounting plate 504 is realized; the cooperation of the connecting shaft 502 and the vertical long hole 505 brings great convenience and flexibility to the rotation operation of the protective mounting plate 504. This design enables the protective mounting plate 504 to be easily and smoothly rotated when needed. Whether switching from a protection state to a detection state, or vice versa, the operation is very simple and quick. In actual applications, this flexible rotation design can meet the rapid changes of different scenarios and user needs.

[0029] Further, such as Figure 1 and Figure 2 As shown, a plurality of elongated mounting holes 506 are provided, and the plurality of elongated mounting holes 506 are opened horizontally and vertically respectively; a plurality of horizontal and vertical elongated mounting holes 506 greatly improve the installation adaptability and flexibility of the detection device. This design not only facilitates the user to install according to the specific environment, but also broadens the application scope of the detection device, enabling it to function in more different places and conditions.

[0030] Furthermore, a limiting member is provided between the protective mounting plate 504 and the protective shell 1. The limiting member is used to limit the protective mounting plate 504 when protecting the semiconductor gas sensor body 2. The setting of the limiting member plays a vital role in ensuring the stability of the protective mounting plate 504 in the protective position. In the protective state, the detection device may be subject to various external interferences. The limiting member can effectively reduce the accidental movement of the protective mounting plate 504, thereby always maintaining effective protection for the semiconductor gas sensor body 2. This not only enhances the safety of the equipment when not in use, but also reduces the possibility of the sensor body 2 being exposed to risks due to the displacement of the protective mounting plate 504, providing reliable protection for the long-term storage and transportation of the equipment.

[0031] Further, such as Figure 1As shown, the protective shell 1 has a built-in controller, and a touch screen 3 is also installed on the side of the protective shell 1 close to the semiconductor gas sensor body 2. The touch screen 3 and the controller are electrically connected to the semiconductor gas sensor body 2. The touch screen 3 is used to display the detection data. The design of the built-in controller and the touch screen 3 greatly improves the operation convenience and data visualization of the detection device. The controller can quickly and accurately process and analyze the data collected by the semiconductor gas sensor body 2 to ensure the accuracy and reliability of the detection results. The touch screen 3 provides the user with an intuitive and friendly operation interface, allowing the user to easily perform various settings and operations, allowing the user to more easily obtain and understand the detection data.

[0032] Further, such as Figure 1 As shown, the protective shell 1 is provided with a plurality of heat dissipation vents 101, which are located on one side of the protective shell 1 close to the groove 5. The design of the heat dissipation vents 101 effectively solves the problem of heat accumulation generated by the detection device during operation. The presence of the heat dissipation vents 101 can promote air circulation, quickly take away heat, and keep the temperature inside the device within a suitable range, thereby ensuring stable operation and long life of the detection device.

[0033] Example 2 further optimizes the detection device based on the semiconductor gas sensor provided in Example 1. Specifically, Figure 1 and Figure 3 As shown, the limiting member includes a second magnet 508 mounted on the protective shell 1 and a first magnet 507 mounted on the protective mounting plate 504. The first magnet 507 is used to attract the second magnet 508. The limiting method using magnetic attraction has the effect of simple operation. It does not require a complex mechanical structure and tedious operating steps. The user only needs to push or pull the protective mounting plate 504 to achieve the attraction or separation of the magnets and quickly complete the switching of the protective state.

[0034] When using, refer to Figure 1 , use bolts to pass through the elongated mounting holes 506 to fix the protective mounting plate 504 on a supporting object, such as a wall, and use the semiconductor gas sensor body 2 to detect the gas state in the target area. When the target area no longer needs to be detected, unscrew the bolts and remove the present application from the supporting object, rotate the protective mounting plate 504 180 degrees around the connecting shaft 502, and then push the protective mounting plate 504 in the direction close to the touch screen 3 so that the first magnet 507 and the second magnet 508 are attracted, that is, Figure 6 As shown, at this time, the first magnet 507 and the second magnet 508 can limit the protective mounting plate 504, and the protective mounting plate 504 can protect the semiconductor gas sensor body 2. It should be noted that Figure 6In this state, the elongated mounting hole 506 does not overlap with the semiconductor gas sensor body 2 and the heat dissipation port 101; when using again, pull the protective mounting plate 504 away from the touch screen 3 to separate the first magnet 507 and the second magnet 508, continue to pull the protective mounting plate 504 until it cannot be pulled anymore, and rotate the protective mounting plate 504 around the connecting shaft 502 to reset it.

[0035] Example 3 further optimizes the detection device based on the semiconductor gas sensor provided in Example 1. Specifically, Figure 4 and Figure 5 As shown, the limiting member includes a limiting groove 509 provided on the side of the protective mounting plate 504 and a chamber 510 provided in the protective shell 1. A limiting rod 511 is slidably connected in the chamber 510. One end of the limiting rod 511 passes through the chamber 510. An elastic member 512 is provided between the other end of the limiting rod 511 and the inner wall of the chamber 510. The force of the elastic member 512 can drive the limiting rod 511 to extend. The number of the limiting rods 511 is the same as the limiting groove 509. The limiting groove 509 is provided on both sides of each protective mounting plate 504. Such an arrangement can improve the stability of the protective mounting plate 504 when limiting. The elastic member 512 is a spring or elastic rubber.

[0036] Further, such as Figure 4 and Figure 5 As shown, the cross-section of the limiting groove 509 is hemispherical, and the end of the limiting rod 511 away from the elastic member 512 is also hemispherical. This arrangement allows the limiting rod 511 to be separated from the limiting groove 509 when the limiting rod 511 is plugged into the limiting groove 509 and the protective mounting plate 504 is pulled hard.

[0037] When using, refer to Figure 1 , use bolts to pass through the elongated mounting holes 506 to fix the protective mounting plate 504 on a supporting object, such as a wall, and use the semiconductor gas sensor body 2 to detect the gas state in the target area. When the target area no longer needs to be detected, unscrew the bolts and remove the present application from the supporting object, rotate the protective mounting plate 504 one hundred and eighty degrees around the connecting shaft 502, and then push the protective mounting plate 504 in the direction close to the touch screen 3 and insert it into the groove 5. At this time, the protective mounting plate 504 squeezes the limiting rod 511 to make the limiting rod 511 retract. When the limiting rod 511 is aligned with the limiting groove 509, the force of the elastic member 512 pushes the limiting rod 511 to insert into the limiting groove 509, so as to limit the protective mounting plate 504, that is, Figure 6 As shown, the semiconductor gas sensor body 2 can be protected by the protective mounting plate 504. It should be noted that Figure 6In this state, the elongated mounting hole 506 does not overlap with the semiconductor gas sensor body 2 and the heat dissipation port 101; when using it again, pull the protective mounting plate 504 away from the touch screen 3 to separate the limit rod 511 from the limit groove 509, continue to pull the protective mounting plate 504 until it cannot be pulled anymore, and rotate the protective mounting plate 504 around the connecting shaft 502 to reset it.

[0038] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
