[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 and Figure 2 As shown, this is a preferred embodiment of the filter disinfection assembly 2 of this utility model. Specifically, it includes: a filter 3, a support 21, and a disinfection module 8. The filter 3 is detachably mounted on the support 21, and the support 21 forms a water flow channel 22. The inlet of the disinfection module 8 is connected to a water supply module. The disinfection module 8 is used to generate water containing oxidized groups. The outlet of the disinfection module 8 is connected to the water flow channel 22, and the water containing oxidized groups is guided to the filter 3 through the water flow channel 22.

[0025] The filter disinfection component 2 proposed in this application can be applied to household, commercial, and industrial equipment that requires filters, and its beneficial effects are as follows:

[0026] The water supply module supplies water to the disinfection module 8. The water is converted into water containing oxidized groups by the disinfection module 8. The water is guided to the filter screen 3 through the water flow channel 22 formed on the support 21 to disinfect the filter screen 3. The water containing oxidized groups produced by the disinfection module 8 is rich in oxidized groups, which can effectively oxidize, kill and degrade bacteria, viruses and other microorganisms, prevent the growth of bacteria on the filter screen 3 during long-term use, and prevent the water from the filter screen 3 from flowing back and contaminating the water in the water tank 6 of the equipment, thus ensuring the effectiveness and reliability of the filter screen 3 and the equipment using the filter screen 3.

[0027] The disinfection module 8 has an inlet and an outlet. The water supply module is connected to the inlet, such as a water tank or a water pipe. The outlet is connected to the water channel 22 of the bracket 21, so that the water is guided to the filter screen 3 to wet the filter screen 3 and pass through, so that the water containing oxidized groups disinfects the filter screen 3.

[0028] In order to guide water containing oxidized groups to the filter screen 3, in one embodiment, the support 21 is provided with a guide channel. For example, the outlet of the guide channel is close to the installation position of the filter screen 3, and the water outlet is guided to the filter screen 3 through the guide channel.

[0029] In one embodiment, for example, the outlet of the guide channel is located near the top of the filter screen 3. In this embodiment, the water containing oxidized groups generated in the disinfection module 8 flows downward from the top of the filter screen 3, ensuring that the water quickly permeates downward. For example, the filter screen disinfection component 2 can be applied to an electrical appliance, wherein the water tank 6 of the appliance is located at the bottom, so that the water overflowing from the filter screen 3 can return to the water tank 6 for recycling, and the generated water containing oxidized groups can disinfect the water tank 6.

[0030] To achieve sterilization and disinfection of filter 3, in one embodiment, the disinfection module 8 includes several electrolysis units, each including a first electrode 81 and a second electrode 83. By electrolyzing water at low pressure, oxidizing groups such as ozone, hypochlorous acid, and oxygen atoms are generated to kill and degrade bacteria and viruses.

[0031] In one embodiment, the electrolysis unit further includes an electrolyte membrane 82 disposed between the first electrode 81 and the second electrode 83. For example, the electrolyte membrane 82 is a proton exchange membrane (PEM), which provides a hydrogen ion channel, i.e., the H+ generated at the anode... + The protons migrate to the cathode through the proton exchange membrane, thereby increasing the reaction rate and the product formation rate.

[0032] In one embodiment, the electrode material of the first electrode 81 and / or the second electrode 83 is one of conductive silicon, conductive diamond, or elemental titanium, platinum, lead, tantalum, iridium, palladium, or their oxides. In one embodiment, the first electrode 81 is the cathode, and the material of the first electrode 81 can be platinum, stainless steel, titanium, etc. The second electrode 83 is the anode, and the material of the second electrode 83 can be one of conductive silicon, conductive diamond, or elemental titanium, platinum, lead, tantalum, iridium, palladium, or their oxides, or other conductive materials. In one embodiment, the electrode materials of the first electrode 81 and the second electrode 83 are one of conductive silicon, conductive diamond, or elemental titanium, platinum, lead, tantalum, iridium, palladium, or their oxides. Electrode switching between the first electrode 81 and the second electrode 83 can be achieved by changing the current, thereby reducing the problem of scale such as calcium carbonate adhering to the electrode surface.

[0033] Among them, the oxide groups generated by the disinfection module 8 are converted into ordinary oxygen after air purification, that is, water containing oxide groups is converted into ordinary water, which is non-toxic and safe.

[0034] In one embodiment, the disinfection module 8 further includes a hydrogen collection unit. The cathode side of the electrolysis unit is provided with a hydrogen outlet, which is connected to the hydrogen collection unit. The hydrogen collection unit is used to collect the hydrogen generated by the disinfection module 8.

[0035] This utility model provides an air purifier for filtering and decomposing pollutants in the air to purify the air, including the filter disinfection component 2 described in any of the above claims. For example, as... Figure 1 and Figure 2 As shown, specifically, the air purifier also includes a housing 1 and a fan assembly 7. The fan assembly 7 and the filter disinfection assembly 2 are disposed inside the housing 1. The housing 1 has an air inlet 10 and an air outlet 11. The fan assembly 7 is used to generate negative pressure to draw outside air into the housing 1, where it is filtered by the filter 3 and discharged from the air outlet 11. In this embodiment, the fan generates negative pressure, and outside air enters the machine through the air inlet 10. Large particles and other impurities are filtered out by the filter 3, and the purified air is discharged to the outside through the air outlet 11. The disinfection module 8 converts the water in the water tank 6 into water containing oxidized groups and transports it to the filter 3 through a water channel. The water is adsorbed by the filter 3, and the water containing oxidized groups can effectively kill and degrade bacteria and viruses on the surface of the filter 3, thereby slowing down the growth of microorganisms on the surface of the filter 3, preventing air from being contaminated during the filtration process, and ensuring the reliability of air purification. Furthermore, when air passes through filter 3, the humid filter 3 can effectively increase the humidity of the air passing through, which in turn regulates the humidity of the air discharged from the air outlet 11.

[0036] In one embodiment, the air purifier further includes a water tank 6, which is a water supply module and is connected to a disinfection module 8 via a pipeline. Further, for example, the air purifier also includes a water pump 5, which supplies water from the water tank 6 to the disinfection module 8 via a pipeline, enabling the water in the water tank 6 to be delivered to the disinfection module 8 to generate water containing oxidized groups and then delivered to the filter 3.

[0037] This invention provides a humidifier for increasing air humidity, including the filter disinfection component 2 described in any of the above-mentioned embodiments. Specifically, the air purifier further includes a housing 1 and a fan. The fan and the filter disinfection component 2 are disposed within the housing 1. The housing 1 has a water tank 6 and an air outlet 11. The water tank 6 is connected to the water inlet of the disinfection module 8, and the disinfection module 8 guides water containing oxidized groups to the filter 3 through a water flow channel 22. The fan accelerates airflow, promoting water evaporation on the filter 3. The filter 3 is an evaporative filter 3 with water absorption properties, such as a high-density fiber filter 3 or a porous ceramic filter 3. In this embodiment, the water in the water tank 6 is converted into water containing oxidized groups by the disinfection module 8 and transported to the filter 3. The fan accelerates evaporation, thereby achieving the purpose of humidifying the air. The water containing oxidized groups can effectively kill and degrade bacteria and viruses on the surface of the filter 3, slowing down the growth of microorganisms on the surface of the filter 3 and preventing the blown-out humidified air from being contaminated.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
