Description

Technical Field

[0001] This utility model relates to the field of air purification by establishing a gradient flow field indoors, and specifically to an antibacterial return air unit with a fan. Background Technology

[0002] Traditional air conditioning systems are mostly designed based on the principles of mixed ventilation and "dilution," resulting in severe mixing of the supplied air with indoor polluted air. This easily leads to the spread of pollutants indoors and poor air cleanliness in controlled areas. For example, ICU wards in Chinese hospitals are often designed with turbulent airflow, lacking protection for medical staff and air barriers to prevent the airborne transmission of infectious viruses. There is also a risk of air leakage as air enters the filter. Therefore, those skilled in the art have provided an antibacterial return air unit with a fan to solve the problems mentioned in the background. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an antibacterial fan return air unit, including a body, a flow equalization mask, a sealing strip, a high-efficiency filter, a double "O"-shaped sealing groove and a sealing strip. The flow equalization mask is installed on the front side of the body, and the high-efficiency filter is installed on the inner side of the front end of the body. The high-efficiency filter is provided with a double "O"-shaped sealing groove, and the sealing strip is installed in the double "O"-shaped sealing groove. The sealing strip is installed on the side wall of the sealing strip.

[0004] Preferably, the machine body has an airflow zone inside, a No. 1 screw hole is provided on the front side wall of the machine body, a No. 2 screw hole is provided on the flow equalization mask, and countersunk screws are installed in the No. 1 screw hole and the No. 2 screw hole;

[0005] Preferably, the flow equalization mask has a sealing groove on the rear side, and a sealing strip is inserted into the sealing groove;

[0006] Preferably, a microporous air supply unit is installed at the upper part of the inner side of the machine body, a fan is installed inside the microporous air supply unit, and a differential pressure controller is installed at the rear part of the inner side of the machine body.

[0007] The technical effects and advantages of this utility model are as follows:

[0008] 1. The flow equalization mask is designed with a sealing strip. When the sealing strip is inserted into the double "O" groove of the HEPA filter, it can ensure that the incoming air enters the HEPA filter without leakage.

[0009] 2. The high-efficiency filter used in this utility model increases the filtration area, reduces the face velocity of the filter material per unit area under the same air volume, reduces the resistance to the passing air, and all components are made of antibacterial materials.

[0010] 3. It realizes intelligent control of return air distribution based on indoor pollution sources. With the help of the micro-pressure formed by the flow field, the staff are placed on the upwind side of the clean airflow, and the pollution sources are on the downwind side. The polluted gas is collected and killed along the shortest path. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example

[0020] Please see Figures 1-6 In this embodiment, an antibacterial fan return air unit is provided, including a body 1, a flow equalization mask 2, a sealing strip 4, a high-efficiency filter 5, a double "O"-shaped sealing groove 101 and a sealing strip 401. The flow equalization mask 2 is installed on the front side of the body 1, and the high-efficiency filter 5 is installed on the inner side of the front end of the body 1. The high-efficiency filter 5 is provided with a double "O"-shaped sealing groove 101, and the sealing strip 401 is installed in the double "O"-shaped sealing groove 101. The sealing strip 401 is installed on the side wall of the sealing strip 4.

[0021] Specifically, the machine body 1 has an airflow zone 102 inside, a first screw hole 103 on the front side wall of the machine body 1, a second screw hole 201 on the flow equalization mask 2, countersunk screws 8 are installed in the first screw hole 103 and the second screw hole 201, a sealing groove 202 is provided on the rear side of the flow equalization mask 2, a sealing strip 4 is inserted into the sealing groove 202, a micro-hole air supply unit 3 is installed at the upper end of the inner side of the machine body 1, a fan 6 is installed in the micro-hole air supply unit 3, and a differential pressure controller 7 is installed at the rear end of the inner side of the machine body 1.

[0022] The working principle of this utility model is as follows:

[0023] An antibacterial fan-driven return air unit is used in places where a unidirectional laminar flow field needs to be formed indoors, such as the medical infectious disease isolation ward to prevent cross-infection between medical staff and patients. This return air unit is generally located near the pollution source so that polluted air enters the return air inlet through the shortest path. When several return air units are installed in a room, different return air volume settings can be achieved. A significant feature of the antibacterial fan-driven return air unit provided by this utility model is that the replacement of the high-efficiency filter 5 will not affect the staff, because the high-efficiency filter 5 uses antibacterial filter material, and the viruses and bacteria blocked by the filter material can be effectively killed. The flow equalization mask 2 is designed with a sealing strip 4. When the sealing strip 401 is inserted into the double "O"-shaped sealing groove 101 of the high-efficiency filter 5, it can ensure that the incoming air enters the high-efficiency filter 5 without leakage. The high-efficiency filter 5 used in this utility model has an increased filtration area, which reduces the face velocity of the filter material per unit area under the same air volume and reduces the resistance to the passing air.

[0024] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
