Description

Technical Field

[0001] The utility model belongs to the technical field of air purifiers, and particularly relates to an electrostatic adsorption structure of an air purifier. Background Art

[0002] Existing air purification generally involves air entering the cathode electric field plate, causing the dust and particles in the air to carry the cathode ions. When the air passes through the anode electric field plate, the mutual adsorption force between the cathode and anode ions causes the dust and particles carrying the cathode ions to be adsorbed onto the anode electric field plate, thereby adsorbing the dust and impurities inside the air to achieve the need for air purification.

[0003] At present, a Chinese utility model with publication number: CN219550763U discloses an ozone-free ion electrostatic adsorption air purifier, including a base, a universal wheel is fixed to the lower surface of the base, an adjustment mechanism is provided on the upper surface of the base, a chassis is provided on the upper surface of the base, an air intake hopper is fixed to the upper surface of the chassis, a connection box is fixed to the inner top wall of the chassis, an exhaust fan is fixed to the lower surface of the connection box, an electrostatic plate is fixed between the front inner wall and the rear inner wall of the purification plate, and a cleaning mechanism is provided on the inner bottom wall of the chassis. The ozone-free ion electrostatic adsorption air purifier can, through the cooperation of a dust collector, suck away the dust adsorbed by the electrostatic plate in the purification plate through the dust inlet pipe, thereby avoiding frequent cleaning of the electrostatic plate, through the cooperation of a dust outlet pipe, the dust in the dust collector can be discharged into the storage box, so that the dust can be stored and stored for easy handling, and through the cooperation of a drawer, the dust can be easily cleaned, thereby reducing the workload of cleaning.

[0004] However, the electrostatic adsorption structure of the existing air purifier can carry cathode ions after the dust in the air passes through the cathode electric field plate. However, when passing through the anode electric field plate, after the air passes through the holes of the anode electric field plate, some of the air is at the edge of the hole, while some is at the center of the hole. Therefore, when the air passes through the center of the hole, the impurities inside the air will be farther away from the anode electric field plate at the edge of the hole, and thus will be less adsorbed by the anode ions. In addition, due to the fast air flow rate, the anode ions cannot fully adsorb this part of the dust and impurities, resulting in omissions. At the same time, because the anode field plate will adhere to the surface of the anode field plate after adsorbing the dust, the surface of the anode field plate will be seriously covered with dust for a long time, thereby forming a layer of dust, which makes it impossible for the anode ions to contact the dust carrying the cathode ions in the air, thereby greatly reducing the adsorption effect of the anode field plate on the dust. Utility Model Content

[0005] The utility model aims to provide an electrostatic adsorption structure for an air purifier, which has the advantages of improving the adsorption effect on dust in the air and facilitating the cleaning of dust accumulated on the surface of the anode electric field plate.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an electrostatic adsorption structure of an air purifier, comprising an air purifier shell, a fan is fixedly installed at the bottom of the inner cavity of the air purifier shell, a mounting tube is installed at the top of the inner cavity of the air purifier shell, an anode plate and a cathode plate are fixedly installed at the top and bottom of the inner cavity of the mounting tube respectively, a cathode through hole is opened inside the cathode plate, an anode through hole is opened inside the anode plate, and the inside of the anode through hole is an inverted V-shaped through hole; a long ash storage box rotatably connected to the mounting tube is arranged between the cathode plate and the anode plate, a fan blade plate is fixedly sleeved on the bottom of the long ash storage box, and a long brush rod slidably connected to the bottom of the anode plate is fixedly connected to the top of the long ash storage box.

[0007] By adopting the above technical scheme, the inner diameter of the anode through hole will gradually decrease as it moves upward, so that the distance between the inner edge of the anode through hole and the center is gradually closer, so that the dust passing through the center of the anode through hole can get close to the anode plate, and then the impurities inside the air at the center of the air purifier shell are adsorbed into the inside of the anode through hole, thereby reducing the omission of dust after adsorption and improving the purification effect of the air purifier; the air moves upward from the cathode plate to push the fan blade plate to drive the long brush rod to rotate, and when too much dust accumulates inside the anode through hole, it rolls down and accumulates at the bottom of the anode plate, so that the long brush rod can scrape off the dust accumulated at the bottom of the anode through hole during the rotation process, and the scraped dust is caught by the long brush rod, thereby achieving the function of cleaning up the dust accumulated on the surface of the anode electric field plate, reducing the cleaning frequency, and facilitating use.

[0008] The utility model is further configured as follows: the housing, the top and the bottom of the air purifier are all opened and are respectively fixedly mounted with an air outlet filter and an air inlet filter, and the top of the air outlet filter is arc-shaped.

[0009] The above technical solution is adopted to prevent large particles of impurities or insects from entering, thereby improving practicality.

[0010] The utility model is further configured as follows: the surface of the bottom of the air purifier housing is provided with air inlet grooves used in conjunction with the fan.

[0011] By adopting the above technical solution, the air purifier can draw air for purification from the bottom close to the ground and discharge the clean air to the top, thereby effectively reducing dust on the ground.

[0012] The utility model is further configured as follows: a slide groove used in conjunction with a mounting tube is provided on one side of the interior of the air purifier housing, and a mounting plate is bolted to one side of the exterior of the air purifier housing close to the slide groove.

[0013] By adopting the above technical solution, the mounting cylinder can be removed from the inside of the air purifier housing, thereby facilitating the cleaning of the dust stored in the long ash storage box.

[0014] The utility model is further configured as follows: a sealing gasket is bonded to one side of the mounting plate close to the inside of the air purifier housing.

[0015] By adopting the above technical solution, the sealing between the mounting plate and the air purifier housing is improved, thereby preventing air leakage.

[0016] The utility model is further configured as follows: a control panel used in conjunction with the fan is fixedly installed on a side of the outside of the air purifier housing away from the slide slot.

[0017] The above technical solution is adopted to facilitate the control of starting and shutting down the air purifier.

[0018] The utility model is further configured as follows: magnet sheets magnetically connected to each other are installed on one side of the outside of the installation tube close to the air purifier shell and one side inside the air purifier shell.

[0019] The adoption of the technical solution makes it easier to install and disassemble the installation tube, thus improving practicality.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The inner diameter of the anode through hole will gradually decrease after passing upward, so that the distance between the inner edge and the center of the anode through hole will gradually get closer, so that the dust passing through the center of the anode through hole can get close to the anode plate, and then the impurities in the air at the center of the air purifier shell are adsorbed into the setting inside the anode through hole, thereby reducing the omission of dust after adsorption and improving the purification effect of the air purifier;

[0022] 2. The air moves upward from the cathode plate to push the fan blade plate to drive the long brush rod to rotate. When too much dust accumulates inside the anode through-hole, it rolls down and accumulates at the bottom of the anode plate. The long brush rod can scrape off the dust accumulated at the bottom of the anode through-hole during its rotation, and the long brush rod is used to catch the scraped dust, thereby facilitating the cleaning of dust accumulated on the surface of the anode electric field plate, reducing the cleaning frequency, and facilitating use.
