[0026] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and accompanying drawings. Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the following detailed description is illustrative rather than restrictive and should not be used to limit the scope of protection of the present invention.

[0027] The accompanying drawings illustrate various cross-sectional views of embodiments disclosed herein. These figures are not drawn to scale; for clarity, some details are exaggerated and some details may be omitted. The shapes, relative sizes, and positional relationships of the various regions and layers shown in the figures are merely exemplary and may deviate in practice due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art may design regions / layers with different shapes, sizes, and relative positions based on actual needs.

[0028] The present invention provides an air purification product regeneration device, such as Figure 1 As shown, it includes: a shell, the shell includes a gas inlet located on the upper side and a gas outlet located on the lower side; and a rotating disk, an electrode plate, a high-voltage power supply and an air humidifier arranged in the shell; the electrode plate is located on the lower side of the gas outlet, and a plurality of air outlets are arranged on it, the high-voltage power supply is coupled to the electrode plate, and is used to apply a current higher than a set threshold voltage to the electrode plate; the rotating disk is located on the lower side of the electrode plate, and the material forming the rotating disk is a conductive material, and the rotating disk is coupled to a grounded wire, and the wire is controlled to be turned on and off by a grounding switch; the air humidifier contains water, and humidifies the air by atomizing the water.

[0029] The present invention provides an air purification product regeneration device, which is provided with a rotating disk, an electrode plate, a high-voltage power supply and an air humidifier. When in use, the air purification product is placed on the rotating disk, and a high-voltage current is applied to the electrode plate through the high-voltage power supply. When the rotating disk is grounded, the rotating disk is at zero potential, and the voltage difference causes the charge to migrate to the air purification product carried by the rotating disk, thereby regenerating the air purification product charge, so that the air purification product can be reused. At the same time, the high-voltage electric field can generate hydroxyl free radicals to kill viruses in the air purification product. In addition, when the grounding switch is disconnected, the liquid is discharged through the air humidifier. Under the action of the high-voltage power supply, the rotating disk and the electrode plate form an ionization device, which can ionize the wet air humidified by the air humidifier, and the negative ions formed by the ionization can be used for air purification, PM2.5 removal, humidification and VOCs removal.

[0030] Please continue to combine Figure 1 The present invention will be described in detail.

[0031] In a preferred embodiment, the water in the present invention can be a relatively pure aqueous solution, such as distilled water, purified water, deionized water, or conventional water with impurity ions, which is not limited in the present invention.

[0032] The present invention uses a high-voltage power supply to apply high voltage (typically 10-50 kV) to the electrode plate. Preferably, to improve charging efficiency, multiple needle-like protrusions are formed on the surface of the electrode plate near the rotating disk. These protrusions create an intermittent discharge effect, smoothly guiding electrons into the air purification product placed on the rotating disk.

[0033] Under the action of a high-voltage power supply, the rotating disk and the electrode plate form an ionization device that can ionize wet air, and the negative ions formed by the ionization can be used for air purification, humidification and VOCs removal. In some preferred embodiments, in order to make the ionization more sufficient, the air humidifier includes a filter component, an electronic atomization component and a liquid storage container. The liquid storage container contains water, and the filter component is used to filter the water. The electronic atomization component is used to atomize the water filtered by the filter component. After the water is atomized by the atomization component, it can be fully dispersed between the electrode plate and the rotating disk, thereby making the ionization more sufficient, which can improve the disinfection effect and air purification efficiency of the air purification product.

[0034] Furthermore, in a preferred embodiment, the gas inlet and / or the gas outlet is a gas grid, that is, the gas inlet in the present invention can be set as a gas grid, and the gas outlet can also be set as a gas grid. The gas grid has the function of physically isolating impurities in the passing gas, thereby avoiding the influence of impurities in the air on the air purification product.

[0035] Furthermore, in a preferred embodiment, the gas inlet or gas outlet includes a filter to filter dust particles in the air that are larger than a set size, i.e., "large dust particles" in the conventional sense, thereby forming a double-layer filtration with the gas grid.

[0036] In some preferred embodiments, in order to improve the disinfection effect of the air purification product, a through hole can be provided on the rotating disk to pass through the upper and lower surfaces. This is beneficial to the air circulation above and below the rotating disk, so that the negative ions generated by ionization can enter the air purification product with the help of the air circulation through the through hole (that is, from the upper side of the rotating disk through the through hole into the lower side of the rotating disk, and then pass through the air purification product), and then use the potential energy of the air flow to increase the amount of hydroxyl free radicals entering the air purification product, thereby improving the disinfection effect.

[0037] In some embodiments, the air purification product regeneration device further includes: a fan, which is coaxially arranged with the rotating shaft of the rotating disk and is located on the lower side of the rotating disk or in a cavity inside the rotating disk.

[0038] The fan rotates along with the rotating shaft, thereby forming an airflow within the housing. The air purification product is disinfected by free hydroxyl radicals in the flowing air, increasing the probability of the air purification product coming into contact with hydroxyl radicals and thereby improving disinfection efficiency. In a preferred embodiment, the air humidifier is located on the lower side of the rotating disk and surrounds the rotating shaft of the rotating disk. In this embodiment, with the help of the through-holes in the above-mentioned embodiment, water is atomized and passes through the through-holes from bottom to top into the air purification product, and is ionized directly within the air purification product.

[0039] During use, the air first passes through the grille at the gas inlet to remove most of the large dust particles, and then enters the shell. The high-voltage power supply applies a high-voltage current to the electrode plate, thereby forming a high-voltage electric field between the electrode plate and the rotating disk, which can ionize the wet air (formed by the humidifier) to form negative ions, purifying the air and removing VOC.

[0040] When removing PM2.5 (inhalable particulate matter), the inhalable particulate matter is partially intercepted by the grille at the gas inlet, and then combined with the negative ions generated by ionization in the shell, thereby removing most of the inhalable particulate matter, and then discharged through the grille at the gas outlet. The grille at the gas outlet intercepts the remaining inhalable particulate matter, and then the inhalable particulate matter in the air is removed through inlet and outlet filtration combined with negative ions.

[0041] When air purification products are placed on the rotating disk, the high-voltage electric field generates hydroxyl radicals, which disinfect the products. Furthermore, when the rotating disk is grounded, it is at zero potential. The voltage difference causes the charge to migrate to the air purification products on the rotating disk, thereby regenerating the charge of the air purification products and making them reusable, thus achieving an integrated disinfection and charging process.

[0042] Of course, the disinfection and charging processes can be performed separately as needed, and the present invention does not limit this.

[0043] In some embodiments, air purification and disinfection charging can be controlled by setting switches, for example, by setting respective switch buttons on the equipment, such as a disinfection charging switch button and a grounding switch button, and manually adjusting the time of each stage. For example, during the regeneration process of a certain air purification product, the high-voltage power supply is first turned on by turning on the disinfection charging switch button, and then hydroxyl radicals are generated under the action of the high-voltage electric field to disinfect the air purification product. At this time, the grounding switch is turned on, the grounding wire is connected, and then the high-voltage electric field regenerates the air purification product. When air purification is required, the grounding switch is turned off, and then the humidifier switch button and the high-voltage power button are turned on. The high-voltage electric field can ionize the humid air to generate negative ions, thereby achieving the functions of air purification, humidification and VOCs removal.

[0044] In a preferred embodiment, the device further comprises: a gravity sensor mounted on the rotating disk; and a controller for regulating the grounding switch to be turned on or off according to changes in the gravity value output by the gravity sensor.

[0045] In this embodiment, the entire device only needs to be provided with a main switch button, that is, as long as the device is operated, the automation of the entire process can be realized, and the specific process is as follows: First, if the switch of the device is turned on (or the power supply of the device is turned on), the controller in the device determines whether an air purification product is placed on the rotating disk based on the force data fed back by the gravity sensor (for example, if the force fed back by the gravity sensor becomes higher, it means that an air purification product is placed on the rotating disk. If the force does not change, it means that no air purification product is placed). Then a control instruction is generated. If it is determined that the air purification product is placed, the air humidifier is controlled to be turned on, the high-voltage power supply is turned on, and the grounding switch is turned on at the same time to achieve disinfection and charging of the air purification product, as well as air purification, humidification and removal of VOCs at the same time. If it is determined that the air purification product is not placed, the grounding switch is controlled to be closed, the high-voltage power supply is turned on, and the humidifier is turned on to achieve air purification, humidification and removal of VOCs.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
