[0032] exist Figure 1 and Figure 2 The outer anti-fog mechanism 6 includes an electric slide rail 601, a connecting rod 602 and a sponge cleaning roller 603. The electric slide rail 601 is fixedly installed inside the protective cover 4, and the outer part of the electric slide rail 601 is slidably connected to the connecting rod 602, and the sponge cleaning roller 603 is installed outside the connecting rod 602.

[0033] Specifically, through the cooperation of the inner anti-fog mechanism 5 and the outer anti-fog mechanism 6, the anti-fog effect is further achieved, thereby ensuring that the instrument body 3 has a better visual effect, thereby ensuring a more accurate reading.

[0034] exist Figure 1 and Figure 2In the figure, two fixing screws are fixedly installed on the top of the protective cover 4, and the two fixing screws penetrate the protective cover 4 and are threadedly connected to the top of the pipe 1. A visual window 7 is installed on the outside of the protective cover 4, and a sponge cleaning roller 603 is located on the front side of the visual window 7.

[0035] Specifically, when the outside of the viewing window 7 is fogged, the controller drives the electric slide rail 601 to start, driving the sponge cleaning roller 603 to move up and down, so as to scrape off the dust and water mist.

[0036] exist Figure 3 and Figure 4 In the embodiment, there are two electric slide rails 601 , which are respectively located on the left and right sides of the viewing window 7 , and the left and right sides of the connecting rod 602 are respectively connected to the two electric slide rails 601 .

[0038] Specifically, the dustproof net 8 can effectively block dust from entering, thereby protecting the meter body 3 and preventing poor readings due to dust.

[0039] exist Figure 4 and Figure 5 In the embodiment, there are two baffles 506 , which are respectively located outside the two air outlets. The side of the first lead screw 502 away from the motor 501 is interconnected with the rear baffle 506 , and the driving wheel 504 and the driven wheel 505 are meshed with each other.

[0040] Specifically, the controller drives the motor 501 to start, thereby driving the first screw 502 and the driving wheel 504 to rotate, and drives the second screw 503 to rotate synchronously through the engagement of the driving wheel 504 and the driven wheel 505, so that when the motor 501 is started, the two baffles 506 can be driven to rotate through the first screw 502 and the second screw 503, thereby controlling the opening and closing of the air outlet.

[0041] exist Figure 3 and Figure 6 In the embodiment, a side of the second lead screw 503 away from the driven wheel 505 is connected to the top baffle 506 .

[0042] Specifically, when the temperature inside the protective cover 4 is too high, the baffle 506 can be opened to dissipate heat. When the temperature difference between the internal temperature of the protective cover 4 and the external temperature is large, the baffle 506 can be closed to avoid fogging of the equipment.

[0043] exist Figure 6 and Figure 7In the figure, the first fan 507 is located at the top of the electric heating tube 508, the drying box 510 is filled with desiccant, the side of the drying box 510 away from the containing box 509 is installed with an air inlet pipe 9, and the top of the air guide pipe 512 is connected to the annular pipe 514.

[0044] Specifically, by setting the first fan 507, the temperature and humidity sensor 11 will monitor the inside of the protective cover 4 in real time. When the temperature and humidity exceed the threshold, the controller drives the first fan 507 and the electric heating tube 508 to start. The first fan 507 will diffuse the heat of the electric heating tube 508, thereby accelerating the air flow and keeping the protective cover 4 dry.

[0045] exist Figure 5 and Figure 6 In the figure, at least five nozzles 10 are fixedly installed on one side of the annular tube 514 close to the instrument body 3, the anti-fog film 515 includes nano-fluorine element polymer and PET polyester, and a temperature and humidity sensor 11 is fixedly installed on the top of the base 2.

[0046] Specifically, when the controller drives the second fan 511 to start, the wind passes through the air inlet pipe 9 and is dried by the drying box 510 before reaching the air guide pipe 512 , and then enters the annular pipe 514 after being heated by the electric heating wire 513 .

[0047] In summary, when the anti-fog automatic instrument device is used, the protective cover 4 is firstly put on the outside of the instrument body 4 and fixed on the pipe 1 by fixing screws, and the inside of the protective cover 4 is monitored in real time by the temperature and humidity sensor 11. When the threshold is exceeded, the temperature and humidity sensor 11 feeds back the information to the controller, and the controller drives the motor 501 to start, and the rotating first screw 502 and the second screw 503 can drive the baffle 506 to close, and then the controller drives the first fan 507 and the electric heating tube 508 to start, and the first fan 507 will diffuse the heat of the electric heating tube 508, thereby accelerating the air Flow, keep the protective cover 4 dry, and at the same time, when the controller drives the second fan 511 to start, the wind passes through the air inlet pipe 9 and is dried by the drying box 510 to reach the air guide pipe 512, and enters the annular tube 514 after being heated by the electric heating wire 513. When the hot air enters the annular tube 514, it is sprayed out by the nozzle 10, thereby heating the outside of the instrument body 3, thereby drying the water droplets gathered on the surface of the anti-fog film 515, and further achieving the anti-fog effect. Finally, when the outside of the visual window 7 is fogged, the controller drives the electric slide rail 601 to start, driving the sponge cleaning roller 603 to move up and down, so as to scrape off the dust and water mist.

[0048] Furthermore, by setting the motor 501, the controller drives the motor 501 to start, thereby driving the first lead screw 502 and the driving wheel 504 to rotate, and the second lead screw 503 is driven to rotate synchronously through the engagement of the driving wheel 504 and the driven wheel 505, so that when the motor 501 is started, the two baffles 506 can be driven to rotate through the first lead screw 502 and the second lead screw 503, thereby controlling the opening and closing of the air outlet. When the temperature inside the protective cover 4 is too high, the baffle 506 can be opened for heat dissipation. When the temperature difference between the internal temperature of the protective cover 4 and the external temperature is large, in order to avoid fogging of the equipment, the baffle 506 can be closed. By setting the first fan 507, the temperature and humidity sensor 11 will detect the temperature of the protective cover 4. Real-time monitoring is carried out internally. When the temperature and humidity exceed the threshold value, the controller drives the first fan 507 and the electric heating tube 508 to start. The first fan 507 will diffuse the heat of the electric heating tube 508, thereby accelerating the air flow and keeping the protective cover 4 dry. The drying box 510 is limited by setting the containing box 509. When the controller drives the second fan 511 to start, the wind passes through the air inlet pipe 9 and is dried by the drying box 510 before reaching the air guide pipe 512. After being heated by the electric heating wire 513, it enters the annular tube 514. By setting the annular tube 514, when the hot air enters the annular tube 514, it is ejected by the nozzle 10, thereby heating the outside of the instrument body 3, thereby effectively preventing the generation of water mist.

[0049] The electrical components appearing in this article are all connected to the external controller and 220V AC power, and the controller can be a conventional known device that plays a control role such as a computer. The specific model specifications of each device in this article need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
