[0004] The above-mentioned comparative document points out that the device installs an exhaust gas filter at the fan end of the negative pressure system to reduce environmental pollution. The fan position can be adjusted to the upper side of the factory building instead of the side to reduce noise pollution. The positive pressure system is installed with a temperature control unit. However, the air inlet end of the device is not equipped with a filtering device, and thus the cleanliness of the air inside the factory building cannot be guaranteed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides an intelligently adjustable positive pressure maintenance system, which has the advantages of improving the indoor air purification effect, and solves the problem that the air inlet end of the device is not equipped with a filtering device, thereby failing to ensure the air cleanliness inside the factory.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an intelligently adjustable positive pressure maintaining system, comprising a filter square tube and three filter plates, three slots are provided on both sides of the filter square tube, a slide groove is provided on the upper end of the filter square tube, a bracket is fixedly connected to one side of the filter square tube, and a fan is fixedly connected to the inside of the bracket.

[0016] Through the above scheme, the wind blown by the fan blows the baffle open, so that the filtered air can enter the room, and when the fan is turned off, the counterweight block drives the connecting rod through the connecting rod, so that the rotating shaft rotates to drive the wind baffle to rotate and close the air outlet square pipe.

[0017] Furthermore, a dust screen is fixedly connected to one end of the filter square tube away from the bracket.

[0018] Through the above solution, the dust screen is used to prevent larger particles from entering the system, thereby protecting the equipment, pipes and other components inside the system from contamination and damage.

[0019] Furthermore, a mounting plate is fixedly connected to one side of the outer wall of the square air outlet tube.

The three filter plates can effectively filter the dust, particles and other impurities in the air, ensure the air quality in the positive pressure environment, and meet the needs of places with high requirements on air quality. The sealing strip on the outer wall of the mounting block ensures the close connection between the filter plate and the filter square tube, effectively preventing unfiltered air from entering the positive pressure environment and ensuring the filtering effect. The handle design on the upper end of the mounting block makes the installation and removal process of the filter plate simpler and more convenient, and the user operation is more friendly. Due to the modular design between the filter plate and the filter square tube, the system can adjust the number and type of filter plates as needed to meet different filtering needs.

[0034] See also Figure 1 , Figure 2 and Figure 4 , a plurality of rotating shafts 14 are rotatably connected to one side of the inner side of the air outlet square tube 10, and a plurality of outer walls of the rotating shafts 14 are fixedly connected to wind shields 15.

Due to the modular design between the filter plate 6 and the filter square tube 1, the system can adjust the number and type of filter plates 6 as needed to adapt to different filtering needs.

[0036] It should be noted that the positive pressure air pump 11 is used to pressurize the air and inject it into the room, thereby improving the positive pressure effect in the room. It is electrically connected to the barometer 12 and the control box 13, and the positive pressure air pump 11 can be adjusted through the control box 13 according to the data of the barometer 12.

[0037] The working principle of the above embodiment is:

[0038] First, the outside air is passed through the dustproof net 19 of the filter square tube 1 by the fan 5. The dustproof net 19 intercepts larger particles in the air, such as dust and sand. The air that has been initially filtered enters the interior of the filter square tube 1 and is further filtered through three filter plates 6 to remove dust, particles and other impurities in the air. The filtered air enters the room through the air outlet square tube 10 under the action of the fan 5 to maintain the positive pressure environment in the room. At this time, the positive pressure air pump 11 starts to work, pressurizes the air in the air outlet square tube 10 and discharges it into the room, and starts to establish a positive pressure environment. The control box 13 determines the indoor air pressure state according to the data of the barometer 12. If the indoor air If the indoor air pressure is lower than the set value, the control box 13 will adjust the working state of the positive pressure air pump 11 and increase the air flow to increase the indoor positive pressure. If the indoor air pressure is higher than the set value, the control box 13 will reduce the air flow of the positive pressure air pump 11 accordingly to avoid excessive pressurization. When the system needs to be shut down, the fan 5 stops working. Due to the action of the counterweight 18, the wind shield 15 will rotate under the drive of the connecting rod 17 and the connecting rod 16 to close the air outlet square pipe 10 and prevent external air from entering the room. When the filter plate 6 needs to be maintained or replaced, the user can pull the handle 8 to slide the mounting block 7 out of the slide slot 3, and then take the filter plate 6 out of the slot 2 for cleaning or replacement.
