DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In one embodiment, see Figure 1-Figure 8An air purifier and disinfector comprises a filter tank body 1. A support leg 4 inclined outward is arranged below the outer wall of the filter tank body 1, so that the filter tank body 1 can be placed directly on the ground in a vertical state for operation. A filter plate 10 is arranged in the middle of the filter tank body 1. A vertical guide tube 11 is arranged in the middle of the filter plate 10. The upper and lower ends of the guide tube 11 are in a normally open state. A lifting piston 13 is arranged above the filter plate 10. The lifting piston 13 can slide up and down along the inner wall of the filter tank body 1, and because the arrangement is relatively tight, the gas is not The air inlet pipe 12 is arranged vertically in the middle of the lower surface of the lifting piston 13. The outer diameter of the air inlet pipe 12 is slightly smaller than the inner diameter of the guide pipe 11. Therefore, the air inlet pipe 12 can be inserted into the inside of the guide pipe 11 after moving downward. The air inlet pipe 12 can slide along the inner wall of the guide pipe 11, and a sealing device is arranged on the outer wall of the lower end of the air inlet pipe 12, so that the gap between the air inlet pipe 12 and the guide pipe 11 is blocked, so that the gas will not pass through the gap between the air inlet pipe 12 and the guide pipe 11. The middle part of the air inlet pipe 12 is the middle The structure is hollow, an air inlet 16 is set at the lower half of the side wall of the air inlet pipe 12, and the gas between the lifting piston 13 and the filter plate 10 can enter the interior of the air inlet pipe 12 through the air inlet 16, and an air outlet nozzle 15 is set on the upper surface of the lifting piston 13, and the air outlet nozzle 15 is connected with the air inlet pipe 12, so the gas can be discharged through the air outlet nozzle 15 after entering through the air inlet 16, and an air extraction device 2 is set below the side wall of the filter tank body 1, and the air extraction device 2 can be an air pump, and the air outlet end of the air pump is connected to the bottom of the filter tank body 1, and the air pump is connected to the inner wall of the filter tank body 1. After being turned on, the external gas is drawn in by the air pump and enters the bottom of the filter tank body 1, achieving the effect of air intake. The incoming gas passes through the filter plate 10 from bottom to top to achieve the filtering effect. The filtered gas enters the interior of the air inlet pipe 12 through the air inlet port 16, and finally flows to the top of the filter tank body 1 through the air outlet nozzle 15 to be discharged. As the air extraction device 2 works, the gas below the filter tank body 1 is continuously drawn into the interior of the filter tank body 1 for filtering treatment, and can be discharged from the top of the filter tank body 1 after the filtering is completed, thereby achieving air purification.

[0026] In one case of the present embodiment, the filter plate 10 is provided with air holes 19, so that the gas can pass through the air holes 19 from bottom to top to achieve a filtering effect, and in order to improve the filtering effect, a mounting slot 18 can be provided on the lower surface of the filter plate 10, and a filter element is installed in the mounting slot 18. The function of this filter element is similar to that of a cylindrical filter element in an ordinary purifier. Only for the convenience of installation, the filter element is designed to be an annular structure, so that the filter element can be more conveniently installed on the lower surface of the filter plate 10, and because the gas cannot flow through the gap between the guide tube 11 and the intake pipe 12, the gas can only pass through the filter element and the filter plate 10 to move upward, thereby ensuring the purification effect of the gas, and the dust and impurities in the gas will adhere to the lower surface of the filter element, making the subsequent cleaning of the filter element more convenient.

[0027] In one case of the present embodiment, a stopper 14 cooperating with the lifting piston 13 is provided above the inner wall of the filter tank body 1. When the lifting piston 13 moves upward, it will contact the stopper 14, and the stopper 14 will block the further rise of the lifting piston 13. At this time, the air inlet pipe 12 below the lifting piston 13 is still inside the guide tube 11 and has not separated from the guide tube 11. The maximum rising height of the lifting piston 13 is limited by the stopper 14, which avoids the air inlet pipe 12 from being separated from the guide tube 11, so that the gas can only be discharged through the air outlet nozzle 15 on the lifting piston 13 after being filtered by the filter plate 10, thereby ensuring the continuous filtering effect of the gas.

[0028] In one case of the present embodiment, the interior of the lifting piston 13 is provided with an air outlet cavity 20 which is connected to the interior of the air inlet pipe 12. The bottom of the air inlet pipe 12 is in a sealed state, and the air outlet nozzle 15 is connected to the air outlet cavity 20. Therefore, when the lifting piston 13 rises a certain distance, the air inlet port 16 on the side wall of the air inlet pipe 12 moves to above the filter plate 10. At this time, the gas between the filter plate 10 and the lifting piston 13 can enter the interior of the air inlet pipe 12 through the air inlet port 16, and the lower end of the air inlet pipe 12 is blocked, so the gas will enter the air outlet cavity 20 of the upper lifting piston 13. By setting the air outlet cavity 20, the flow rate of the gas can be reduced, so that the gas can be discharged more smoothly through the air outlet nozzle 15, and the air outlet nozzles 15 are evenly distributed on the upper surface of the lifting piston 13, so that the gas can enter the top of the filter tank body 1 more evenly.

[0029] In one case of the present embodiment, a sealing ring 17 is provided on the outer side of the lifting piston 13, and the sealing ring 17 is used to improve the air tightness between the lifting piston 13 and the inner wall of the filter tank body 1. At this time, a storage cavity is formed inside the filter tank body 1 and above the lifting piston 13, and disinfectant can be injected into this cavity. The disinfectant can neutralize or sterilize some pollutants in the gas, which can better complete the purification and disinfection of the gas compared with a single filter element filtration. In addition, due to the provision of the sealing ring 17, the disinfectant will not leak downward through the lifting piston 13 and the inner wall of the filter tank body 1, and a one-way valve is provided inside the air outlet nozzle 15, so that the gas can only enter from the bottom of the air outlet nozzle 15 and be output from the top of the air outlet nozzle 15, thereby preventing the disinfectant above from entering the air outlet cavity 20 inside the lifting piston 13 through the air outlet nozzle 15.

[0030] In one case of this embodiment, an exhaust pipe 3 communicating with the inside of the filter tank body 1 is provided at the top of the side wall of the filter tank body 1. The exhaust pipe 3 is evenly distributed compared to the center of the filter tank body 1, and the exhaust pipe 3 is horizontally arranged on the side wall of the filter tank body 1, so that during normal use, external dust will not enter the inside of the exhaust pipe by falling, avoiding secondary pollution of the inside of the filter tank body 1 by external air, and because the exhaust pipe 3 faces different directions, the gas purified by the filter tank body 1 can be evenly discharged into the environment.

[0031] In one case of this embodiment, a debris removal component 9 is provided at the bottom of the filter tank body 1, and the air extraction device 2 is located between the debris removal component 9 and the filter plate 10. The debris removal component 9 includes a material guide funnel 8 fixedly connected to the inner wall of the filter tank body 1, and the middle part of the material guide funnel 8 is concave downward. When the lifting piston 13 falls downward, it will collide with the filter plate 10. At this time, the dust dropped from the filter plate 10 will fall on the upper surface of the guide hopper 8, and the dust will slide toward the middle along the guide hopper 8 and fall to the bottom of the guide hopper 8. The guide hopper 8 is provided to prevent the fallen dust from flowing upward again. A guide slope 7 is provided at the lower end of the filter tank body 1, so the dust dropped from the guide funnel 8 will gather toward the middle along the guide slope 7, and a vertical downward discharge pipe 6 is provided in the middle of the guide slope 7. The dust will slide into the inside of the discharge pipe 6, and a storage hopper 5 is installed at the lower part of the discharge pipe 6 by threaded connection. Therefore, the dust dropped into the discharge pipe 6 will remain in the storage hopper 5. After the entire purification and disinfection machine has worked for a period of time, the storage hopper 5 can be taken out to pour out the dust retained in the storage hopper 5, and a cleaning window can be provided on the side wall of the filter tank body 1. After opening the cleaning window, the filter element below the filter plate 10 can be replaced. In addition, the pressure of the gas below the filter tank body 1 is changed by the vacuum device 2, so that the impact force does not need to be achieved through the gravity of the lifting piston 13. It is only necessary to reduce the pressure below the filter tank body 1. The space above the lifting piston 13 is connected to the outside through the exhaust pipe 3, so that the lifting piston 13 is pulled downward to achieve the impact effect. At this time, the entire filter tank body 1 can be placed horizontally or even inverted, but disinfectant cannot be injected above the filter tank body 1.

[0032] During the implementation of this embodiment, the filter element is installed on the lower surface of the filter plate 10, and disinfectant is injected above the filter tank body 1, and it is ensured that the disinfectant will not leak after the lifting piston 13 moves to a high position. At this time, the purification and disinfection machine can work normally after power is connected.

[0033] In the gas filtering process, the exhaust device 2 draws the gas outside the filter tank body 1 into the bottom of the filter plate 10. At this time, the gas pressure below the filter plate 10 gradually increases. When the air pressure on the lifting piston 13 is greater than the gravity of the lifting piston 13, the lifting piston 13 is pushed upward by the gas. At this time, the gas passes through the filter plate 10 and moves between the lifting piston 13 and the filter plate 10. At this time, the gas is filtered once by the filter element. Dust and other impurities in the gas adhere to the lower surface of the filter element. As the lifting piston 13 continues to move upward, the air inlet 16 moves to the top of the guide tube 11, and the gas enters the interior of the lifting piston 13 through the air inlet 16. The gas enters the disinfectant through the air outlet nozzle 15 for chemical neutralization. After the gas moves to the top of the filter tank body 1, it is discharged through the exhaust pipe 3. Therefore, the gas is discharged after being filtered by the filter element and purified by the disinfectant, completing the air purification process.

[0034] Self-cleaning treatment: after the purification and disinfection machine has been working for a period of time, the vacuum device 2 is stopped. At this time, the lifting piston 13 drops rapidly under the gravity of the lifting piston 13, and the lifting piston 13 hits the filter plate 10, thereby causing the filter element to vibrate. The dust attached to the lower surface of the filter element will be shaken off onto the guide funnel 8 and slide into the storage hopper 5 via the guide slope 7. Since the space between the lifting piston 13 and the filter plate 10 is small, the increase in air pressure below the filter tank body 1 caused by the fall of the lifting piston 13 will not affect the fall of the lifting piston 13. Alternatively, the vacuum device 2 can be started in reverse during the cleaning process, so that part of the gas below the filter tank body 1 is extracted to the outside of the filter tank body 1, so that the lifting piston 13 can fall smoothly and complete the impact on the filter plate 10. In addition, a filtering device is arranged inside the vacuum device 2 to prevent the dust shaken off the filter element from being discharged to the outside of the filter tank body 1, and the disinfectant above the filter tank body 1 will be mixed during the rapid falling of the lifting piston 13, so that the uniformity of the disinfectant is better, which is convenient for the subsequent purification and disinfection of the disinfectant. If the dust cannot be completely shaken off after one impact, the vacuum device 2 can be started in reverse again, so that the lifting piston 13 is pushed up again and then falls, so that the lifting piston 13 falls and hits the filter plate 10 multiple times, so that the dust on the surface of the filter element is effectively shaken off, and if there is no self-cleaning treatment for a long time, the air permeability of the filter element will be reduced, and the gas cannot push the lifting piston 13 upward, resulting in the inability of the gas to flow, thereby preventing the filter element itself from contaminating the flowing gas, and reminding the user to replace the filter element at this time.

[0035] The present invention is applicable to an air purification and disinfection machine. By setting a lifting piston 13 that moves up and down to impact the filter plate 10, the dust attached to the surface after the gas is filtered is shaken off, thereby achieving a self-cleaning effect, so that the filter element can shake off the dust on the surface after working for a period of time, thereby extending the service life of the filter element and reducing the use cost of the purification and disinfection machine.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
