Embodiment 1

[0036] Please refer to Figure 1-Figure 3 , the present embodiment provides a protection device 100, which includes a fixed seat 10 and a movable top cover 20, the fixed seat 10 has a receiving groove 11 for accommodating the electrochemical sensor 200, and the movable top cover 20 is rotatably connected to the fixed seat 10. The fixed seat 10 is provided with an air intake passage 12 and an exhaust passage 13 communicating with the storage tank 11. The intake passage 12 is used to input the protective gas and discharge the gas in the storage tank 11 from the exhaust passage 13. The protection device 100 There is a first state in which the movable top cover 20 is away from the accommodating groove 11 and the accommodating groove 11 is opened, and a second state in which the movable top cover 20 closes the accommodating groove 11 and makes the electrochemical sensor 200 in a closed chamber.

[0037] figure 1 The protection device 100 shown in FIG. 2 is in the first state, at t...

Embodiment 2

[0061] Please refer to Figure 4 , this embodiment also provides a protection device 100, the technical solution described in embodiment 1 is also applicable to this embodiment, and the disclosed technical solution in embodiment 1 will not be described again.

[0062] Specifically, the difference between this embodiment and Embodiment 1 is that the protective device 100 further includes a gas container 80 for storing protective gas, the output part of the gas container 80 communicates with the intake passage 12, and the gas container The input part of the device 80 communicates with the connecting pipe 70.

[0063] During specific implementation, a large amount of protective gas can be filled into the gas container 80 first, so that the inside thereof is in a state of high pressure.

[0064] When inflation is required, the solenoid valve 60 is opened, and the gas container 80 instantly inflates the air intake passage 12, so that the protective gas quickly fills the containing...

Embodiment 3

[0068] This embodiment also provides a sensor structure, which includes the aforementioned protection device 100 and has all the functions of the protection device 100 .

[0069] For the structure of the protection device 100, reference may be made to Embodiment 1 or 2.

[0070] The sensor structure also includes an electrochemical sensor 200 connected to the fixing base 10 and located in the receiving groove 11 .

[0071] To sum up, the present invention provides a protection device 100, which can open the receiving tank 11 when needed, so that the electrochemical sensor 200 can be exposed to the external space for normal operation. , protecting the electrochemical sensor 200 is beneficial to improving the service life of the electrochemical sensor 200 . The structure has reasonable design, strong practicability, and huge market application potential.

Abstract

The invention provides a protection device and a sensor structure and belongs to the technical field of electrochemical sensors. The protection device comprises a fixed seat and a movable top cover, wherein the fixed seat is provided with an accommodating groove used for accommodating an electrochemical sensor; the movable top cover is rotationally connected with the fixed seat, the fixed seat isprovided with an air inlet channel and an air exhaust channel both communicated with the accommodating groove, and the air inlet channel is used for inputting protective gas and allowing gas in the accommodating groove to be discharged from the air exhaust channel. The protection device can open the accommodating groove when needed, so that the electrochemical sensor is exposed in an external space for normal work; when not needed, the electrochemical sensor is protected, so that the service life of the electrochemical sensor is favorably improved. The sensor structure comprises the protectiondevice and has all functions of the protection device.

Description

technical field [0001] The invention relates to the technical field of electrochemical sensors, in particular to a protection device and a sensor structure. Background technique [0002] The earliest electrochemical sensors date back to the 1950s, when they were used for oxygen monitoring. By the mid-1980s, small electrochemical sensors were used to detect many different toxic gases in the PEL range and showed good sensitivity and selectivity. [0003] Currently, various electrochemical sensors are widely used in many static and mobile applications for personal safety. [0004] The inventor found in the research that there are at least the following shortcomings in the existing related technologies: [0005] Improper use of electrochemical sensors; [0006] The service life is shorter. Contents of the invention [0007] The purpose of the present invention is to provide a protection device that improves the deficiencies of the prior art. It can open the receiving tank ...
