Description

Technical Field

[0001] The present application relates to the technical field of wind cabinets, and in particular to a wind cabinet for air purification. Background Art

[0002] Wind cabinets use physical or chemical methods to remove pollutants, dust, bacteria, viruses, harmful gases, etc. from the air to provide a clean and healthy air environment. They are often used in hospitals, laboratories, data centers, offices, shopping malls, etc. After a period of use, the filter element inside the wind cabinet is prone to thick dust, which affects the filtering effect. Therefore, the filter element needs to be cleaned and maintained regularly. However, most of the existing air purification wind cabinets are integrated, which is not convenient for cleaning the filter element, resulting in a short service life of the air purification wind cabinet.

[0003] In order to facilitate the cleaning of the filter element in the wind cabinet and thus increase the service life of the wind cabinet, the present application provides a wind cabinet for air purification.

[0004] The above invention objectives of the present application are achieved through the following technical solutions:

[0005] A wind cabinet for air purification comprises a cabinet body, wherein a drawer-type frame is movably arranged inside the cabinet body, and the drawer-type frame divides the cabinet body into two upper and lower cavities;

[0006] The top and bottom of the drawer-type frame are both provided with mesh, and two insertion slots are arranged in parallel inside the drawer-type frame, a cold catalyst filter layer is fixedly arranged between the two insertion slots, and the insides of the two insertion slots are both movably connected with activated carbon filter components;

[0007] The top of the cabinet is connected to an air intake pipe, the air intake pipe extends to the side wall of the cabinet, the air intake pipe is connected to an air intake fan, and the outer wall of the air intake fan is fixedly connected to the side wall of the cabinet;

[0008] The bottom end of the side wall of the cabinet is connected with an exhaust pipe, the exhaust pipe extends to the top of the cabinet, the exhaust pipe is connected with an exhaust fan, and the outer wall of the exhaust fan is fixedly connected to the side wall of the cabinet.

[0009] By adopting the above technical scheme, the drawer-type frame divides the cabinet into two upper and lower cavities, the air intake fan draws the outside air into the air intake pipe, and discharges it into the top of the cabinet through the air intake pipe, and two activated carbon filter assemblies and cold catalyst filter layers are arranged in parallel inside the drawer-type frame. The air at the top of the cabinet falls into the bottom of the cabinet after being filtered by the activated carbon filter assembly and the cold catalyst filter layer, and the exhaust pipe on the side wall at the bottom of the cabinet, with the cooperation of the exhaust fan, draws the filtered gas and discharges it outside the cabinet to achieve the purpose of air purification. When it is necessary to clean and replace the activated carbon filter assembly and the cold catalyst filter layer inside the cabinet, the drawer-type frame is pulled out of the cabinet, and then the activated carbon filter assembly is pulled out of the insertion slot for cleaning and maintenance, thereby improving the service life of the wind cabinet.

[0010] Optionally, a plurality of limit blocks are arranged in parallel on the outer wall of the drawer-type frame, and a plurality of slide grooves are opened on the inner wall of the cabinet. When the drawer-type frame is installed inside the cabinet, the limit blocks correspond to the slide grooves one by one and fit in an adaptable manner.

[0011] By adopting the above technical solution, the limit block corresponds to the slide groove one by one and fits in with it. When installing or disassembling the drawer-type frame, the drawer-type frame drives the limit block to slide back and forth inside the slide groove. When the drawer-type frame is moved toward the inside of the cabinet to the extreme position, one end of the drawer-type frame extends to the surface of the cabinet, making it easy to pull out the drawer-type frame.

[0012] Optionally, the activated carbon filter assembly includes a filter frame, and an activated carbon filter layer is fixedly arranged inside the filter frame.

[0013] By adopting the above technical solution, an activated carbon filter layer is fixed inside the filter frame. The air at the top of the cabinet is filtered through the activated carbon filter layer, the cold catalyst filter layer and the activated carbon filter layer in sequence and then falls into the bottom of the cabinet. The activated carbon filter layer can absorb odors in the air, and the cold catalyst filter layer can decompose harmful substances such as formaldehyde, benzene, toluene, xylene, etc. in the air through catalysis, thereby improving the air purification effect.

[0015] By adopting the above technical solution, the mounting hole is opened in the side wall of one end of the drawer-type frame. When the drawer-type frame moves to the extreme position inside the cabinet, one end of the drawer-type frame extends to the surface of the cabinet, and the mounting hole is located outside the cabinet. The disassembly and assembly component is arranged on the side wall of the filter frame. When the filter frame is inserted into the insertion slot to the extreme position, the disassembly and assembly component passes through the drawer-type frame through the mounting hole, so that the filter frame can be detachably fixed to the drawer-type frame through the disassembly and assembly component, which has the effect of improving the convenience of disassembly and assembly of the filter frame.

[0016] Optionally, the disassembly and assembly assembly includes a mounting groove, a return spring and an embedded plate, the mounting groove is opened on the side wall of the filter frame, one end of the return spring is fixedly connected to the inner wall of the mounting groove, the other end of the return spring is fixedly connected to the embedded plate, and one end of the embedded plate is rotatably connected to the side wall of the filter frame.

[0017] By adopting the above technical solution, the mounting hole is opened in the side wall of the drawer-type frame, one end of the reset spring is fixedly connected to the inner wall of the mounting groove, and the other end is fixedly connected to the surface of the embedded plate, the embedded plate is rotatably connected to the side wall of the filter frame, and the filter frame is installed in the insertion groove by pressing the embedded plate. When the filter frame is inserted to the extreme position, the reset spring resets the embedded plate, and the embedded plate extends out of the drawer-type frame through the mounting hole, so that the filter frame and the drawer-type frame can be detachably fixed, thereby facilitating the disassembly and assembly of the filter frame and the drawer-type frame.

[0018] Optionally, the embedded plate is rotatably connected to the side wall of the filter frame via a hinge structure, and a baffle is fixedly connected to one end of the embedded plate away from the hinge structure;

[0019] The embedding plate and the baffle are adapted to be embedded in the mounting hole.

[0020] By adopting the above technical solution, the embedded plate is rotatably connected to the side wall of the filter frame through a hinge structure, and a baffle is fixedly connected to the end of the embedded plate away from the hinge structure. The baffle protects the embedded plate and the reset spring to prevent the reset spring and the embedded plate from being squeezed by the side wall of the drawer-type frame due to external force and causing damage. The embedded plate and the baffle are adapted to be embedded in the mounting hole, so that the clamping structure of the embedded plate and the baffle is more stable when they are embedded in the mounting hole, which has the effect of improving the practicality and service life of the disassembly and assembly components.

[0021] Optionally, handles are fixedly provided on one end of the filter rack extending out of the insertion slot and on both side ends of the drawer-type frame.

[0022] By adopting the above technical solution, handles are fixedly provided on one end of the filter rack extending from the insertion slot and on both side ends of the drawer-type frame. When disassembling and assembling the filter rack and the drawer-type frame, the handles provide a holding position for the operator, thereby improving the convenience of operation.
