[0026] The present embodiment provides a liquid-based air circulation purification device, including a shell 9 and a device body placed inside the shell 9; the device body includes a power system, a filtering system 19, a driving system, a control system, a wetting recovery system 15, a sealing mechanism, and a liquid storage tank 22 arranged at the bottom of the device body; the wetting recovery system 15 integrates a spraying mechanism and a liquid recovery mechanism into one.

[0027] The power system uses a fan to provide air flow power. The fan can be an axial fan or a centrifugal fan to select a suitable wind configuration according to actual needs. The power system also includes an air guide cover and a filter baffle 24. The air guide cover is used to guide air flow and optimize air circulation efficiency; the filter baffle 24 is used to prevent large objects from entering the system, ensuring the normal operation of the equipment and avoiding damage to the fan or other key components.

[0028] The housing 9 is provided with a human-machine interface 25, and is provided with ventilation holes on four sides, and is equipped with pulleys at the bottom to facilitate the movement and transportation of the device. A fixing seat buckle 1 is provided on the inner wall of the housing 9, and the device body includes a fixing seat 2, and is connected to the housing 9 through the fixing seat buckle 1. A fan mounting hole 10 is installed on the fixing seat 2, and the fan is arranged above the fixing seat 2 and concentrically arranged with the fixing seat 2, and the motor driving the fan is arranged at the center of the fixing seat 2.

[0029] The device body also includes a fixed bracket 20, which is located below the fixed seat 2, and the filter system 19 is installed in the internal space enclosed by the fixed bracket 20. The center of the filter system 19 is connected to the centrifugal motor 8 of the drive system to realize coaxial transmission. The filter screen of the filter system 19 rotates around the axis under the action of the centrifugal motor 8, and the rotation speed can be controlled by the speed of the centrifugal motor 8 and can be switched between low gear and high gear; a solid phase filter layer is attached to the filter screen of the filter system 19, and the solid phase filter layer adopts a solid porous material. At the same time, the purification device of this embodiment can add a negative ion generator on the front or rear side of the filter screen to further enhance the purification effect; the filter screen can be grounded to enhance its electrostatic adsorption capacity, thereby improving the filtering effect on tiny particles.

[0030] An annular wetting recovery system 15 is coaxially sleeved on the outer periphery of the filtering system 19, and uniformly distributed nozzles 17 are provided on the inner side of the wetting recovery system 15. The wetting recovery system 15 is respectively connected to the water pumps 18 in the purified liquid area and the polluted liquid area of ​​the liquid storage tank 22 through flexible pipelines. The wetting recovery system 15 extracts purified liquid through the water pump 18 and sprays the purified liquid to the filtering system 19 through the nozzles 17. The purified liquid is combined with the porous material on the filter screen to form a filtering system, thereby purifying the air introduced by the fan.

[0031] In order to allow the purified liquid to be evenly sprayed onto the filter system 19, the wetting recovery system 15 is lifted and lowered along the height direction of the filter system 19 under the action of the drive system. Specifically, a coupling 11 is provided on the fixed seat 2, and the coupling 11 is connected to a transmission screw 12, and the transmission screw 12 is arranged along the height direction of the filter system 19, and the lifting motor 7 of the drive system is connected to the transmission screw 12 through the coupling 11. It also includes a packaging chassis 16, the lower end of the transmission screw 12 is fixed to the packaging chassis 16, and an optical axis 13 parallel to the transmission screw 12 is also arranged between the fixing seat 2 and the packaging chassis 16, and a bearing sleeve 14 is installed on the optical axis 13. The wetting recovery system 15 is connected with the transmission screw and the bearing sleeve 14, and the lifting motor 7 drives the wetting recovery system 15 to rise and fall along the optical axis 13 through the transmission screw, so that the wetting recovery system 15 can move up and down under the action of the lifting motor 7, cooperate with the rotation of the filtering system 19, spray the purified liquid evenly onto the filtering system 19, and help the purified liquid to be evenly dispersed in the solid porous material.

[0032] In order to ensure that the wetting and recovery structure does not exceed the predetermined range during movement, thereby avoiding mechanical damage and ensuring the stability and safety of the equipment, a photoelectric baffle 23 is also provided on the wetting and recovery system 15 to locate the position of the wetting and recovery system 15, thereby being used to accurately control the displacement range.

[0033] A camera may also be added to the wetting recovery system 15 to monitor the spraying and recovery process of the liquid in real time. Through the human-computer interaction interface 25, the user can view the real-time image and evaluate the compounding of the liquid and the solid to optimize the operation effect. As a simple alternative to this embodiment, the spraying mechanism and the recovery mechanism of the wetting recovery system may also be divided into two independent separate mechanisms.

[0034] The outer side of the wetting recovery system 15 is surrounded by a closing mechanism; the closing mechanism can be switched between an open state and a closed state under the action of the driving system, so that the device can switch between the purification process and the recovery process; when the closing mechanism is in the open state, the filter system 19 rotates at a low speed, the wetting recovery system 15 is lifted and lowered along the height direction of the filter system 19 under the action of the driving system, and the purification liquid is sprayed to the filter system 19, and the purification liquid is combined with the solid phase filter layer to purify the air introduced by the power system; when the closing mechanism is in the closed state, the wetting recovery system 15 is attached to the inner wall of the closing mechanism, and the filter system 19 rotates at a high speed, so that the filtered polluted liquid falls into the wetting recovery system 15 for recovery under the action of centrifugal force. The polluted liquid falling into the wetting recovery system 15 is pumped into the polluted liquid area of ​​the liquid storage tank 22 by the water pump 18 for recovery.

[0035] Specifically, the closure mechanism is composed of six closed baffles 21 evenly distributed on the outside of the filter system 19, an annular transmission gear ring 4 is installed on the fixed seat 2, and the fixed seat 2 is also provided with a plurality of transmission gears 3 meshing with the transmission gear ring 4. The transmission gear ring 4 rotates under the drive of the driving gear 5, and drives the transmission gear 3 to rotate. The driving gear 5 is driven by the driving motor 6. The upper end of the closed baffle 21 is installed at the bottom of the fixed seat 2 and connected with the transmission gear 3. The lower end of the closed baffle 21 passes through the hole at the bottom of the fixed bracket 20 and is rotatably connected with the fixed bracket 20. The transmission gear ring 4 is driven to rotate by the driving gear 5, thereby driving the transmission gear 3 to rotate. The transmission gear 3 is connected to the closed baffle 21, so that the closed baffle 21 can be driven to open and close around the fixed bracket 20 on the outside of the filter system 19. The outer side of the wet recovery system 15 is provided with a flexible material. When the closed baffle 21 is closed, the outer side of the wet recovery system 15 can be tightly fitted with the inner side of the closed baffle 21 due to the flexible material.

[0036] The control system includes a single-chip minimum system, a sensor communication circuit, a screen communication circuit, a motor drive circuit, a relay drive circuit, a host computer communication circuit and a power management circuit, which are used to control the work of each mechanism and system in the purification device to ensure the coordinated operation of the system. At the same time, the control system is responsible for completing the transmission and real-time display of data, providing a user-friendly operation interface, real-time monitoring of the equipment status, and optimizing the control and adjustment of the purification process.

[0037] When the purification equipment is in the purification process, the control system controls the driving gear 5 to rotate, thereby opening the closed baffle 21 to ensure that the air is in a circulating state. At the same time, the control system turns on the centrifugal motor 8 and the lifting motor 7. The filter system 19 rotates at a low speed under the action of the centrifugal motor 8. The wetting recovery system 15 rises and falls along the height direction of the filter system 19 under the action of the lifting motor 7, and sprays the purification liquid to the filter system 19. The purification liquid is evenly sprayed on the filter screen of the filter system 19, and is combined with the porous material thereon to form a filtration system. At this time, the user can view the real-time image through the human-computer interaction interface 25 on the shell 9 to evaluate the composite situation of the purification liquid and the solid. The fan of the power system introduces air into the purification equipment and flows into the air outside the equipment through the ventilation hole after being filtered by the filter system formed by the purification liquid and the porous material. The purification liquid can choose to replace different purification liquid components according to the different pollutant characteristics in the air. The filtered purification liquid absorbs pollutants in the air to form a polluted liquid.

[0038] When it is necessary to recycle the contaminated liquid, the user can switch the purification device to the recycling process, and when the control system controls the driving gear 5 to rotate, the closing baffle 21 is closed to form a closed chamber, and the filter system 19 is sealed inside it. At the same time, the control system controls the centrifugal motor 8 and the lifting motor 7, and the filter system 19 rotates at a high speed under the action of the centrifugal motor 8, and the wetting recovery system 15 is positioned to the recovery position under the action of the lifting motor 7. The outer wall of the wetting recovery system 15 is close to the closing baffle 21, and the closing baffle 21 prevents the contaminated liquid from being thrown out of the device. The contaminated liquid falls into the wetting recovery system 15 under the action of centrifugal force and the blocking of the closing baffle 21. The wetting recovery system 15 is provided with an annular groove for catching the contaminated liquid. The contaminated liquid falling into the wetting recovery system 15 is transported to the contaminated liquid area of ​​the liquid storage tank 22 under the action of the water pump 18, thereby completing the recovery.

[0039] Furthermore, corresponding sensors can be arranged in the liquid storage tank 22 to detect the type of pollutants in the polluted liquid. The signals collected by the sensors are transmitted to the control unit of the control system, thereby realizing real-time monitoring and processing optimization of the pollutants and improving purification efficiency and flexibility.

[0040] The liquid-based air circulation purification equipment of this embodiment can realize the construction of a liquid gated purification system by setting up a filtration system 19, a wetting recovery system 15, a closing mechanism, a control system and a power system. The cooperation of the filtration system 19 and the wetting recovery system 15 can realize the uniform compounding and recovery of liquid and porous materials in various scenarios, and can be realized without replacing the filter membrane. In addition, by deploying different liquids, multi-functional and multi-field purification can be achieved, thereby improving the air purification efficiency and functional diversity.
