Description

Technical Field

[0001] The utility model relates to the technical field of virus filtering in indoor environments of buildings, in particular to a virus filtering device for central air conditioners. Background Art

[0002] With the development of industry, air pollution is becoming more and more serious. When the concentration of pollutants in the air reaches or exceeds the harmful level, it will lead to the destruction of the ecosystem and the normal survival and development of human beings, causing harm to people and organisms. In addition to harmful gases and particulate matter, there are a large number of microorganisms such as bacteria and viruses in the pollutants in the air. Some of them are attached to the particles in the air. Particles with a diameter greater than 10μm can fall to the ground together with microorganisms such as bacteria and viruses. Particles with a diameter less than 10μm can carry bacteria and viruses and float in the air for a long time; the other part is contained in droplets. When people sneeze, cough, sing, and talk, droplets are sprayed from the mouth and nostrils. The bacteria and viruses in the droplets or the "droplet nuclei" formed by the evaporation of droplets can quickly disperse everywhere in the room and float in the indoor air for a long time, which can easily cause the spread of respiratory infectious diseases.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A virus filtering device for a central air conditioner in a preferred embodiment of the utility model includes a main body 1, which is a rectangular cavity 11 with an opening on one side. A first filter component 2, a second filter component 3 and a switching component 4 are arranged in the rectangular cavity 1. The switching component 4 includes a sliding member 41 and a sealing member 42. The sealing member 42 moves with the sliding member 41 to close the air inlet of the first filter component 2 and / or the second filter component 3. The air inlet on the first filter component 2 and the air inlet on the second filter component 3 are arranged at different heights.

[0024] Through the above scheme, when the ambient temperature or virus concentration changes, the switching component 4 can be automatically or manually adjusted to expose the air inlet of the first filter component 2 and / or the second filter component 3, so that different purification methods can be switched according to the actual usage scenario. It can not only expand the purification range of the virus filter device, but also reduce the aging rate of each component, so that the purification effect of the virus filter device is more stable and lasting.

[0025] In the above embodiment, the sliding member 41 includes a guide rail 411 and a sliding plate 412, the sliding plate has at least a first area and a second area, the sealing member 42 in the first area is provided with a first opening 413 corresponding to the air inlet on the first filter component 2, the first opening 413 passes through the sliding plate 412, the sealing member 42 in the second area is provided with a second opening 414 corresponding to the air inlet on the second filter component 3, the second opening 414 passes through the sliding plate 412, and the guide rail 411 is connected to the rectangular cavity 11.

[0026] Through the above scheme, the air inlet that is not in use can be closed by moving the sliding plate 412, which can reduce the probability of untreated air entering the rectangular cavity 11, thereby effectively ensuring the purification quality. To achieve this purpose, the seal 42 adopts a rubber block connected to the inner side of the sliding plate 412. The rubber block is arranged along the extension direction of the seal 42, which can reduce the flow of air between different air inlets.

[0027] In at least one of the embodiments, the first filter component 2 includes a mounting frame 21, a support layer 22 is provided in the mounting frame 21, and an antibacterial and antiviral filter layer 23 is provided on the support layer 22; the support layer 22 is used to support the antibacterial and antiviral filter layer 23, and the antibacterial and antiviral filter layer 23 is used to adsorb and kill microorganisms such as bacteria and viruses in the air.

[0028] In the above embodiment, the antibacterial and antiviral filter layer 23 is a nano-plated antibacterial and antiviral microporous membrane.

[0029] Through the above technical solution, the installation frame 21, the support layer 22, and the antibacterial and antiviral filter layer 23 cooperate with each other, simplifying the structure of the filter, thereby reducing the difficulty of the filter production process and reducing the production cost. At the same time, due to the simple structure, it is easier to clean and replace. By setting the antibacterial and antiviral filter layer 23, microorganisms such as bacteria and viruses in the air are effectively adsorbed and killed. When the antibacterial and antiviral filter layer 23 is set as a nano-plated antibacterial and antiviral microporous membrane, the killing ability of microorganisms such as bacteria and viruses is further improved.

[0030] In at least one of the embodiments, the second filter component 3 includes a rectangular shell 31, a disinfection filter element 32 arranged in the rectangular shell 31, the disinfection filter element 32 is composed of an activated carbon layer 321, a first heating plate 322, a second heating plate 323, a steel mesh 324 for supporting the activated carbon layer and an electrostatic generator 325, and an aerogel insulation material is coated on the outside of the rectangular shell.

[0031] In the above embodiment, the activated carbon layer 321 is located between the first heating plate 322 and the second heating plate 323 .

[0032] In the above embodiment, the first heating plate 322 and the second heating plate 323 are both carbon fiber far-infrared heating plates.

[0033] Through the above technical solution, the electrostatic generator 325 is used to filter and adsorb various harmful substances and viruses in the air onto the activated carbon, and the air entering the disinfection filter element 32 is filtered and sterilized. Under the action of the electrostatic generator, the flowing air is fully in contact with the activated carbon to achieve the purpose of air disinfection and purification, and the indoor air is purified from haze and formaldehyde; it can promote the purification of the air entering the purifier and improve the filtering effect of the air.

By setting the first elastic component 5 and the second elastic component 6, the sliding plate can be limited, reducing the probability of damage to the sliding plate and the guide rail. In the actual implementation process, the first elastic component 5 and the second elastic component 6 are both made of nylon.

[0035] In a typical usage scenario, when the air conditioner is used for cooling, since the low temperature itself will reduce the activity of the virus, making the virus easier to kill, the air inlet of the first filter component 2 is opened to process the air; when the air conditioner is used for heating, the air inlet of the second filter component 3 is opened to process the air, which can not only utilize the carbon fiber far-infrared heating plate to improve the killing effect on germs and viruses, but also preheat the air, thereby improving the heating response speed of the air conditioner and improving the user experience.

[0036] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the scope of the specific implementation methods. In summary, the content of this specification should not be understood as a limitation on the present invention.
