[0023] In order to better understand the purpose, structure and function of the present invention, an air purification device of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, the present application provides an air purification device, including a shell 1 with an air duct, the air inlet 11 and the air outlet 12 of the air duct are respectively arranged on the bottom side wall and the top surface of the shell 1, a fan assembly 2 is arranged in the shell 1, and also includes a spray assembly 3 arranged upstream of the fan assembly 2, the spray assembly 3 sprays disinfectant into the air duct to eliminate viruses in the air entering the air duct.

[0025] like Figure 1 As shown, the spray assembly 3 includes a liquid storage tank 31 for containing disinfectant, and the side wall of the liquid storage tank 31 is connected to a liquid outlet pipe 32, which extends upward, and a nozzle 33 is arranged at the end of the liquid outlet pipe 32, and a pump body is arranged on the liquid outlet pipe 32.

[0026] In order to replenish disinfectant into the liquid storage tank 31 in time, a liquid inlet pipe 311 is connected to the side wall of the liquid storage tank 31. The end of the liquid inlet pipe 311 passes through the side wall of the outer shell 1 and extends to the outside of the outer shell 1. The end of the liquid inlet pipe 311 covers the cover body, and the liquid inlet of the liquid storage tank 31 is above the liquid outlet.

[0027] The disinfectant can be a non-volatile alkaline solution with a pH value greater than 9, such as sodium hydroxide solution, potassium hydroxide solution, barium hydroxide solution, lime water, or other non-volatile disinfectants.

[0028] In order to make the sprayed disinfectant have a higher sterilization effect, a disinfection box 4 is arranged above the liquid storage box 31, an air inlet 41 is arranged on the bottom surface of the disinfection box 4, an air outlet is arranged on the top surface, and a liquid outlet pipe 32 passes through the side wall of the disinfection box 4 and extends into the disinfection box 4. The number of the liquid outlet pipes 32 includes at least one, and each liquid outlet pipe 32 passes through different side walls of the disinfection box 4, so that the disinfectant sprayed by the nozzle 33 has a wider range.

[0029] After the disinfectant comes into contact with the air in the disinfection box 4, it moves upward under the action of the fan component 2. In order to prevent the disinfectant from diffusing into the air and to recover the disinfectant, the air purification device also includes a recovery component 5. The air outlet on the top surface of the disinfection box 4 is connected to the recovery box 45. The recovery component 5 is arranged at the exhaust port of the recovery box 45. The recovery component 5 separates the air from the water vapor containing the disinfectant through centrifugal action to achieve the recovery of the disinfectant.

[0030] The recovery box 45 includes a cone, the small diameter end of the cone is connected to the air outlet of the antivirus box 4, the large diameter end of the cone is connected to the column, the top of the column is connected to the partition 6, the partition 6 is fixed in the outer shell 1, and the partition 6 on the inner side of the column is provided with a through hole for air circulation. The recovery component 5 is arranged on the top of the column, thereby providing a closed air duct for disinfecting viruses in the air.

[0031] The recovery component 5 includes a filter screen 51 arranged below the partition 6. The filter screen 51 is used to absorb the disinfectant in the air. The top of the filter screen 51 is connected to the driving shaft of the motor 52. The side wall of the motor 52 is provided with a bracket 53. The bracket 53 passes through the through hole and is fixed on the partition 6. When the motor 52 is turned on, the filter screen 51 rotates at high speed, and the air and disinfectant are separated by centrifugal action.

[0032] In order to detect the content of disinfectant in the air, a humidity sensor 7 is set at the through hole of the partition 6. The humidity sensor 7 and the motor 52 are electrically connected to the controller respectively. When the real-time humidity value detected by the humidity sensor 7 is greater than the humidity threshold, the controller adjusts the rotation speed of the motor 52 to enhance the centrifugal effect.

[0033] A reflux port 42 is provided on the bottom surface of the disinfection box 4 , and the reflux port 42 is connected to a reflux pipe 34 , and the other end of the reflux pipe 34 is connected to the bottom wall of the liquid storage box 31 .

[0034] In order to prevent the disinfectant from flowing out of the air inlet 41 of the anti-virus box 4, Figure 2 As shown, the disinfection box 4 is folded upward at the air inlet 41 to form a retaining ring, and a fog cover 44 is provided above the retaining ring. Support rods 43 are respectively provided on the bottom surface of the fog cover 44. The bottom ends of the support rods 43 are fixed in the disinfection box 4 to effectively prevent the disinfectant from flowing out from the air inlet 41.

[0035] An ultraviolet disinfection component 8 is also provided on the inner wall of the housing 1 between the partition 6 and the fan component 2. The ultraviolet disinfection component 8 is an ultraviolet lamp tube. The ultraviolet lamp tube generates ultraviolet rays to further sterilize the air, making the sterilization effect more thorough.

[0036] After the air purification device is started, the fan assembly 2 starts to run, and the air enters the air duct from the air inlet 11. The pump body pumps the disinfectant in the liquid storage tank 31 to the nozzle 33, and sprays the disinfectant in the disinfection box 4 without dead corners. The air passes through the disinfection box 4, and the viruses and bacteria are inactivated by the disinfectant. Most of the disinfectant after spraying will flow back to the liquid storage tank 31 along the return pipe 34.

[0037] The treated air continues to rise, and a small amount of atomized disinfectant will be carried in the air and adsorbed by the filter 51. Under the action of the motor 52, the atomized disinfectant attached to the filter 51 splashes onto the inner wall of the recovery box 45 under the action of centrifugal force, and flows into the disinfection box 4 along the cone, and flows into the liquid storage tank 31 from the reflux pipe 34.

[0038] Then, the air passing through the recovery component 5 continues to rise under the action of the fan component 2, and the humidity sensor 7 detects the humidity value of the air flowing out of the recovery component 5 to determine the degree of separation of the disinfectant and the air. When the humidity exceeds the humidity threshold, feedback information is given to the controller to control the motor 52 to accelerate the rotation, so that the disinfectant and the air are separated more thoroughly. The filtered air passes through the ultraviolet disinfection component 8, and the ultraviolet rays generated by the ultraviolet disinfection component 8 further disinfect it, and then the purified air is discharged to the outside from the air outlet 12, and the disinfection machine and the outdoor air are continuously circulated to achieve the effect of disinfecting a specific space.

[0039] The air purification device continuously inhales indoor air, and when the inhaled air passes through the air duct, disinfectant is continuously sprayed into the air duct, viruses and bacteria in the air are inactivated by the disinfectant, and the purified air is continuously discharged from the air outlet 12; the disinfectant is collected by the recovery component 5 and reused, thus avoiding continuous consumption. The user does not need to constantly add it, thus saving time and cost. At the same time, by using the recovery component 5, there is no need to spray the disinfectant into the outside air, thus avoiding harmful contact between the disinfectant and the human body.
