[0026] 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.

[0027] Example 1, please refer to Figures 1-4 An electrochemical gas sensor includes a sensor body 1, an electrode body 101 and an air inlet body 102 are provided on the sensor body 1, a protective mechanism 2 for protecting the electrode body 101 is further provided on the sensor body 1, an annular groove 3 is provided on the outer side of the sensor body 1 near one end of the electrode body 101, the protective mechanism 2 includes a connecting ring 209 plugged into the outer surface of the annular groove 3, and a protective mesh cover 210 for protecting the electrode body 101 is fixedly connected to the side of the connecting ring 209 away from the sensor body 1. A connecting ring 209 and a protective mesh cover 210 are provided at one end, so that the protective mesh cover 210 can protect the electrode body 101, greatly reducing the risk of physical damage to the electrode body 101 before use. The protective mesh cover 210 is made of hard material, such as metal, so that it has sufficient strength to protect the electrode body 101, thereby ensuring that the sensor body 1 is in the best condition before it is put into use, reducing the possibility of measurement error or functional failure due to damage to the electrode body 101, and laying a solid foundation for subsequent accurate measurement and stable work.

[0028] Further, such as Figure 3As shown, an annular groove 3 is also provided on the outer side of the sensor body 1 near the end of the air inlet body 102. The design of the annular groove 3 provides the protective mesh cover 210 with precise positioning and stable limiting functions, which enables the protective mesh cover 210 to maintain a stable position during operation and will not shake or shift due to external vibrations, airflow impact or other interference factors, thereby ensuring that the protective mesh cover 210 can accurately cover the area that needs to be protected, give full play to its role, reduce the risk of protection failure due to unstable position, and further ensure the normal operation and measurement accuracy of the sensor.

[0029] In Example 2, the electrochemical gas sensor provided in Example 1 is further optimized. Specifically, the protective mechanism 2 further includes a connector, which is disposed between the sensor body 1 and the protective mesh cover 210 and is used to connect the sensor body 1 and the protective mesh cover 210.

[0030] The addition of the connecting piece establishes a reliable connection bridge between the sensor body 1 and the protective mesh cover 210. It not only enhances the connection strength between the two and ensures that the protective mesh cover 210 is tightly combined with the sensor body 1, but also gives the protective mesh cover 210 adjustability, so that it can change its position according to different working stages and needs. This design greatly improves the adaptability and operability of the sensor. Whether in the protection stage before use or in the function switching stage during use, the expected effect can be easily achieved, further ensuring the performance stability and functional integrity of the sensor.

[0031] Furthermore, the protective mesh cover 210 is also used to prevent dust from entering the air inlet body 102. The protective mesh cover 210 has mesh holes for filtering dust, and the connecting piece is rotatable to switch the position of the protective mesh cover 210. That is, before the sensor body 1 is used, the protective mesh cover 210 can protect the electrode body 101, and when the sensor body 1 is used, the protective mesh cover 210 is rotatably set at the air inlet body 102, that is, Figure 5 As shown, the protective mesh cover 210 is used to filter the air inlet body 102 to reduce the ingress of dust;

[0032] The multifunctional design of the protective mesh cover 210 greatly enhances the overall performance and applicability of the sensor. Before use, it provides critical protection for the electrode body 101, ensuring the initial quality and performance of the sensor. During use, it is switched to the air inlet body 102 via a rotatable connector for dust protection, effectively preventing dust and other impurities from entering the air inlet body 102, avoiding interference with measurement results and damage to the internal structure of the sensor. This not only extends the service life of the sensor, but also significantly improves measurement accuracy and stability, enabling the sensor to maintain good working condition in various harsh environments, reducing maintenance costs and the incidence of failures.

[0033] The sensor faces different challenges and demands in different working stages. Before use, the focus is on protecting the sensitive electrode body 101; while in use, dust prevention of the air inlet body 102 becomes the key. The protective mesh cover 210 can flexibly adapt to these changes, give full play to its role in different stages, and realize maximum resource utilization and optimal performance.

[0034] Further, such as Figures 1-4 As shown, the connecting member includes a second connecting plate 211 fixedly mounted on one side of the sensor body 1 and a first connecting plate 201 located on one side of the second connecting plate 211. A sliding groove 202 is provided on one side of the first connecting plate 201 close to the second connecting plate 211. A slider 203 is slidably connected in the sliding groove 202. A connecting shaft 212 is fixedly connected to one side of the slider 203, and the connecting shaft 212 is rotatably connected to the second connecting plate 211 (the connecting shaft 212 is rotatably connected to the second connecting plate 211 through a bearing). This arrangement allows the first connecting plate 201 to rotate, and the first connecting plate 201 and the slider 203 to move relative to each other to complete the switching operation.

[0035] The cooperation between the slide groove 202 and the slider 203 enables the first connecting plate 201 to slide smoothly within a certain range, thereby realizing position adjustment; and the combination of the connecting shaft 212 and the bearing gives the first connecting plate 201 the ability to rotate, so that the protective mesh cover 210 can be quickly and accurately switched to the desired position. This flexible movement method greatly simplifies the operating process, and the position adjustment of the protective mesh cover 210 can be easily completed, providing a strong guarantee for the normal operation of the sensor.

[0036] Further, such as Figure 4As shown, a connecting rod 204 is fixedly installed in the slide groove 202, and the outer surface of the connecting rod 204 passes through the slider 203 (the connecting rod 204 and the slider 203 can slide relative to each other). The setting of the connecting rod 204 provides reliable support and guidance for the slider 203, effectively preventing the slider 203 from disengaging from the slide groove 202 during movement. This design greatly improves the structural stability and movement reliability of the connecting piece, ensuring that during frequent position switching operations, the slider 203 can always move within the predetermined track and will not accidentally fall off, thereby ensuring the accuracy and stability of the position switching of the protective net cover 210, reducing the risk of operational failures and component damage caused by the dislocation of the slider 203, extending the service life of the connecting piece, and reducing maintenance costs.

[0037] Further, such as Figure 4 As shown, a spring 205 is sleeved on the outer surface of the connecting rod 204, and the two ends of the spring 205 are fixedly connected to the slider 203 and the slide groove 202 respectively. The force of the spring 205 can pull the connecting ring 209 through the first connecting plate 201 to improve the stability of the connection between the connecting ring 209 and the annular groove 3; during the operation of the sensor, even in the face of adverse factors such as strong vibration, impact or temperature changes, the elastic force of the spring 205 can ensure that the connecting ring 209 is always tightly fitted into the annular groove 3, reducing the occurrence of separation, which effectively reduces the risk of protection failure due to loose connection and improves the anti-interference ability and working reliability of the sensor.

[0038] Example 3 further optimizes the electrochemical gas sensor provided in Example 2. Specifically, the connecting ring 209 and the first connecting plate 201 are fixedly connected. The fixed connection can improve the structural stability. This stable connection effectively avoids the degradation of protective performance due to loosening or relative movement of the connection parts during use. Whether in frequent position switching operations or in long-term working operations, the fixed connection can ensure that the protective mesh cover 210 is always closely matched with the sensor body 1, giving full play to its protection and filtering functions. In addition, the fixed connection also reduces the risk of failure due to wear and fatigue of the connection parts, extends the service life of the protective mechanism, reduces maintenance costs and equipment downtime, and improves production efficiency and economic benefits.

[0039] Example 4 further optimizes the electrochemical gas sensor provided in Example 2. Specifically, Figure 1-Figure 2As shown, one side of the connecting ring 209 is fixedly connected to a plug plate 207, and a socket 206 is provided on the first connecting plate 201, and the socket 206 is plugged into the outer surface of the plug plate 207. After the plug plate 207 is separated from the socket 206, the protective mesh cover 210 can be removed to facilitate cleaning of the protective mesh cover 210. The matching design of the plug plate 207 and the socket 206 provides a convenient and efficient way for the disassembly and installation of the protective mesh cover 210. When the protective mesh cover 210 needs to be cleaned or maintained, it can be easily removed, which greatly simplifies the operating process and saves time and labor costs. The detachable design makes it possible to deeply clean the protective mesh cover 210, and can completely remove the dust, impurities and dirt accumulated in the protective mesh cover 210, and restore its good air permeability and filtering performance, which not only helps to maintain the measurement accuracy and stability of the sensor, but also extends the service life of the protective mesh cover 210 and reduces the overall maintenance cost of the equipment.

[0040] Furthermore, a slope is provided on one end of the plug board 207 away from the connecting ring 209 , and the provision of the slope facilitates the insertion of the plug board 207 into the socket 206 .

[0041] When using, refer to Figure 1 At this time, the protective mesh cover 210 protects the electrode body 101. Figure 5 When in use, first pull the protective mesh cover 210 away from the sensor body 1 so that the connecting ring 209 is separated from the annular groove 3 (at this time, the first connecting plate 201 moves downward with the anti-slip mesh cover 210), then rotate the first connecting plate 201 around the connecting shaft 212 so that the protective mesh cover 210 is rotated to the end of the sensor body 1 close to the air inlet main body 102, and push the protective mesh cover 210 toward the air inlet main body 102 so that the connecting ring 209 is plugged into the annular groove 3 of the sensor body 1 close to the air inlet main body 102 (at this time, the first connecting plate 201 moves upward with the anti-slip mesh cover 210), that is, Figure 5 As shown, at this time, the protective mesh cover 210 can prevent dust from entering the air inlet body 102.

[0042] This application adopts the method of setting a connecting ring and a protective mesh cover at one end of the sensor body close to the electrode body, so that the protective mesh cover can protect the electrode body, greatly reducing the risk of physical damage to the electrode body before use, thereby improving the durability and reliability of the sensor. Since the electrode body is better protected, the overall performance of the sensor can be maintained, the overall safety of the product is improved, the service life is extended, and the replacement frequency and cost are reduced.

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.
