Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification and disinfection machine. Background Technique

[0002] The air purification and disinfection machine uses filtration technology to adsorb or kill microorganisms such as bacteria and viruses, and purifies and disinfects the air. The air purification and disinfection machine is divided into a physical disinfection air purification and disinfection machine and a chemical disinfection air purification and disinfection machine according to the disinfection method.

[0003] The physical disinfection air purification and disinfection machine mainly uses a filter for blocking or adsorption, and then irradiates bacteria, viruses and other microorganisms with ultraviolet light to destroy the DNA structure in their cell walls and kill bacteria; however, after the existing equipment is used for about one year, the filter surface is covered with dust, which affects the filtering effect. Since the filter is a whole, it needs to be disassembled and replaced as a whole, which not only has a high maintenance cost, but also is troublesome to disassemble;

[0004] Moreover, the ultraviolet light used has poor penetration ability, there are dead corners in disinfection, and the sterilization effect is poor.

[0005] The chemical disinfection air purification and disinfection machine mainly kills viruses in the air by atomizing the bactericide or generates plasma by low-current high-voltage pulse discharge to ionize substances in the air and destroy viruses and bacteria; however, the excessive use of disinfection and antibacterial agents can accelerate the generation and spread of drug-resistant bacteria. In the hospital environment, due to the frequent use of disinfectants, strains have developed resistance and mutations;

[0006] And during the plasma disinfection process, there will be O3, nitrogen oxides, ultrafine particles and charged particle dust, resulting in a decline in lung function, the development of asthma, an increase in respiratory tract infections, and a higher risk of lung cancer.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution: an air purification and disinfection machine, including a housing 1, an air outlet 11 is provided at the top of the housing 1, a plurality of universal casters 12 are provided at the bottom of the housing 1 to facilitate the movement of the entire machine body, a control panel 13 is provided on the outer wall of the housing 1 for turning on and adjusting the air purification and disinfection machine, a maintenance opening 14 is provided on the rear side wall below the housing 1, and a baffle 141 is provided at the maintenance opening 14. When maintenance is required, the baffle can be opened;

[0029] An air inlet 15 is provided by opening a circle along the outer wall below the housing 1, and an air inlet 15 is also opened on the baffle 141.

[0030] Inside the housing 1, a pre-filter 2, an EC motor fan 3, and a high-temperature-resistant main filter 5 are arranged in sequence from bottom to top. A heater 4 for disinfecting and sterilizing the main filter 5 is arranged below the main filter 5. After each working cycle, the heater is automatically started for heating, generally heated to above 80°C, so as to ensure that the bacteria and viruses in the main filter lose their activity;

[0031] Among them, the pre-filter 2 is fixed below the housing through the mounting bracket 6 and is adjacent to the inspection port 14, which facilitates the subsequent disassembly and replacement of the pre-filter 2.

[0032] After the body is started, the EC motor fan 3 starts to work. Air enters from the air inlet 15. The dusty air passes through the pre-filter 2 for preliminary filtration, first filtering the dust, hair, coarse pollen, cotton wool, etc. in the inhaled air.

[0033] The filtered air will continue to enter the main filter to further filter viruses, bacteria, and odors, etc. The filtered air is finally discharged from the air outlet 11.

[0034] After each working cycle, when the EC motor fan is turned off and the air purification stops, the heater 4 is automatically started to heat the bacteria and viruses in the main filter 5 to make them lose their activity;

[0035] A sound insulation layer 16 can also be provided on the inner wall of the housing 1, which can not only ensure the ultra-quiet operation of the air purification and disinfection machine, but also minimize the heat transfer from the heater 4 to the housing 1 during the cleaning operation of the main filter 5;

[0036] A sensor 17 for real-time monitoring of the carbon dioxide content in the air can also be added inside the housing 1.

[0037] As Figures 5-7 shown, in this embodiment, the mounting bracket 6 is designed with a U-shaped structure. It is fixed on the inner wall of the housing 1 at the inspection port. Sliding grooves 61 are opened on both sides of the mounting bracket 6, a bayonet 62 is opened at the rear of the mounting bracket 6, and a magnetic sheet 63 is arranged in the bayonet 62.

[0038] Sliding strips 21 are arranged on both sides of the pre-filter 2, a magnetic block 22 is arranged on the front side of the pre-filter 2, and a sealing strip 23 is arranged on the rear side of the pre-filter 2;

[0039] The installation operation of the pre-filter is as follows:

[0040] Align the sliding bars 21 on both sides of the pre-filter 2 with the sliding grooves 61 of the mounting bracket, and then push the filter to slide and embed it until the clamping block 22 of the pre-filter is embedded in the bayonet 62 and closely fits with the magnetic sheet 63. Then cover the baffle on the maintenance port 14. At this time, the sealing strip 23 on the rear side of the pre-filter is closely attached to the baffle 141 to prevent gaps from being generated between the pre-filter and the housing.

[0041] In this embodiment, the pre-filter 2 adopts a G4-class primary filter, which can filter particles larger than 10 μm, including pollen, spores, cotton lint, hair, insects, etc.

[0042] In this embodiment, the optimal setting of the universal casters 12 is to install four at the bottom of the machine body, and two of the universal casters 12 are equipped with braking devices for convenient braking and fixing;

[0043] The above-mentioned universal casters 12 generally select industrial rubber universal casters with a diameter of 50 mm, because they have a rubber coating and are suitable for almost any floor.

[0044] As Figure 4 shown, in this embodiment, the heater 4 includes a plurality of U-shaped heating tubes 41, and the plurality of U-shaped heating tubes 41 are close to the bottom of the main filter 5. In this way, after each shutdown, the main filter is heated to above 80 °C by the plurality of heating tubes 41, so as to ensure that the bacteria and viruses in the main filter lose their activity.

[0045] As Figure 4 shown, in this embodiment, the high-temperature-resistant main filter 5 is a four-layer structure filter, and the main filter 5 includes:

[0046] A fine dust pre-filter layer 51 close to the heater 4, which is an F7 fine filter and can filter particles of 1-10 μm, including smoke, bacteria, mold, viruses, etc.;

[0047] A high-performance filter layer 52, which is an H-14 high-performance filter and can filter viruses and bacteria (referring to microorganisms in the form of bacteria, fungi, etc.), with a separation efficiency of >99.995%; the size of the filtered virus is 0.05 to 0.16 μm, and the size of the influenza virus is usually between 0.08 and 0.16 μm, and the size of the filtered bacteria is usually between 0.3 and 0.6 μm;

[0048] An activated carbon filter layer 53, which can filter particles larger than 0.1 μm and reduce odors and remove volatile organic compounds;

[0049] A rear filter layer 54 close to the air outlet 11, which can optimize the uniform air outlet and ensure that no particulate matter penetrates the device from the upper air outlet 11 and damages the main filter.

[0050] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
