Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, specifically to a carbon filter dual-duct air purification device. Background Technology

[0002] As people's living standards improve, more and more people are demanding higher air quality. In order to meet the need for higher air quality, household air purifiers are commonly used to filter and purify the indoor air environment.

[0003] A modular air purifier currently exists with an assembled filter element that is inserted into a frame. After a certain period of use, the filter element can be replaced by disassembly to ensure continuous use. However, in this type of device, the filter element is easily dislodged when the frame is opened for replacement, causing inconvenience. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of modular filter elements easily falling off, and to provide a carbon filter element dual-duct air purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-duct air purification device with a carbon filter element includes a frame, which includes a top plate, a bottom plate, and support columns. The top plate and bottom plate are respectively located at the upper and lower ends of the support columns. Four support columns are provided and fixed at the four corners of the top plate. Block-shaped filter elements are snapped between adjacent support columns. Threaded holes are provided at the bottom of the support columns. Fixing bolts are provided on the bottom plate. The fixing bolts pass through the bottom plate and engage with the threaded holes to lock the bottom plate to the bottom of the support columns. Filter screens made of elastic material are fitted around the filter elements and support columns.

[0007] Furthermore, the lower end of the filter screen sleeve extends to the lower end of the support column and is clamped between the support column and the base plate. The support column and the base plate clamp the bottom of the filter screen sleeve, thereby preventing displacement.

[0008] Furthermore, an air inlet mesh is provided in the center of the top plate, and a purification fan is installed on the bottom plate. The air inlet of the purification fan faces the air inlet mesh, and the air outlet of the purification fan faces the side filter element. A grid mesh is provided in the center of the bottom plate. After the purification fan is working, it generates suction to draw outside air in through the top air inlet mesh, and then the air flows sideways through the filter element for purification before flowing outwards; some air flows out through the grid mesh in the bottom plate.

[0009] Furthermore, a top filter is fixedly connected to the side of the top plate near the purification fan, and the top filter covers the air inlet mesh. The incoming air is initially filtered through the top filter.

[0010] Furthermore, a bottom filter is fixedly connected to the base plate, and the bottom filter covers the mesh of the grille. The air is filtered through the bottom filter.

[0011] Furthermore, a sponge ring is fitted around the outer side of the purifying fan, and the sponge ring is located on the inner wall of the cavity enclosed by the filter element. The air is filtered through the sponge ring, improving the filtration effect.

[0012] Furthermore, the filter element includes a rectangular frame and an activated carbon block embedded within the rectangular frame, the activated carbon block having adsorption pores. The activated carbon block adsorbs and purifies the air, removing harmful substances from the air; after a period of use, the filter element can be removed by disassembling the base plate and replaced with a new one.

[0013] Furthermore, the support column is provided with paired retaining strips, and the rectangular frame of the filter element is inserted between the oppositely arranged retaining strips. The retaining strips limit the position of the filter element, thereby allowing the filter element to be inserted between the retaining strips. At the same time, after removing the base plate, the filter element can be pulled out from between the retaining strips for easy replacement.

[0014] The present invention provides a carbon filter element dual-duct air purification device, which has the following beneficial effects: by providing a filter screen sleeve on the outside of the filter element and the support column, the air can be initially filtered through the filter screen sleeve. At the same time, the elasticity of the filter screen sleeve binds the support column and the filter element tightly, thereby preventing the filter element from falling off between the support columns during disassembly and assembly.

[0021] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0024] like Figures 1-4 As shown, a carbon filter dual-duct air purification device includes a frame, which includes a top plate 11, a bottom plate 12, and support columns 13. The top plate 11 and the bottom plate 12 are respectively disposed at the upper and lower ends of the support columns 13. Four support columns 13 are provided and are respectively fixed at the four corners of the top plate 11. Block-shaped filter elements 2 are snapped between adjacent support columns 13. Threaded holes are opened at the bottom of the support columns 13. Fixing bolts are provided on the bottom plate 12. The fixing bolts pass through the bottom plate 12 and cooperate with the threaded holes to lock the bottom plate 12 to the bottom end of the support columns 13. Filter screen sleeves 3 are sleeved on the outside of the filter elements 2 and the support columns 13. The filter screen sleeves 3 are made of elastic material.

[0025] By adopting the above technical solution, a filter screen sleeve 3 is provided on the outside of the filter element 2 and the support column 13. The filter screen sleeve 3 can perform preliminary filtration of the air. At the same time, the elasticity of the filter screen sleeve 3 binds the support column 13 and the filter element 2 tightly, thereby preventing the filter element 2 from falling off the support column 13 during disassembly and assembly. In use, air enters the purification device from the top and then flows out from the side and bottom dual air ducts of the purification device. The air is adsorbed and purified by the filter element 2.

[0026] Specifically, the lower end of the filter screen sleeve 3 extends to the lower end of the support column 13 and is clamped between the support column 13 and the base plate 12. The support column 13 and the base plate 12 clamp the bottom of the filter screen sleeve 3, thereby preventing the filter screen sleeve 3 from shifting.

[0027] Specifically, the top plate 11 has an air inlet mesh 111 in the middle, and a purification fan 4 is installed on the bottom plate 12. The air inlet of the purification fan 4 faces the air inlet mesh 111, and the air outlet of the purification fan 4 faces the filter element 2 on the side. The bottom plate 12 has a grid mesh 121 in the middle. After the purification fan 4 is working, it generates suction to draw outside air in through the top air inlet mesh 111. Then, the air flows sideways through the filter element 2 for purification and flows outward. Some air flows out through the grid mesh 121 in the bottom plate 12.

[0028] Specifically, a top filter 112 is fixedly connected to the side of the top plate 11 near the purification fan 4, and the top filter 112 covers the air inlet mesh 111. The top filter 112 performs preliminary filtration on the incoming air.

[0029] Specifically, a bottom filter 122 is fixedly connected to the base plate 12, and the bottom filter 122 covers the grid mesh 121. The air is filtered through the bottom filter 122.

[0030] Specifically, a sponge ring 5 is fitted around the outer side of the purification fan 4, and the sponge ring 5 is located on the inner wall of the cavity enclosed by the filter element 2. The air is filtered through the sponge ring 5, improving the filtration effect.

[0031] Specifically, the filter element 2 includes a rectangular frame 21 and an activated carbon block 22 embedded in the rectangular frame 21. The activated carbon block 22 has adsorption pores. The activated carbon block 22 adsorbs and purifies the air, removing harmful substances from the air. After a period of use, the filter element 2 can be removed by removing the base plate 12 and replaced with a new filter element 2.

[0032] Specifically, the support column 13 is provided with paired retaining strips 131, and the rectangular frame 21 of the filter element 2 is inserted between the oppositely arranged retaining strips 131. The retaining strips 131 limit the position of the filter element 2, thereby allowing the filter element 2 to be inserted between the retaining strips 131. At the same time, after removing the base plate 12, the filter element 2 can be pulled out from between the retaining strips 131 for easy replacement of the filter element 2.

[0033] The parts not covered in this technical solution can be implemented using existing technologies.

[0034] The foregoing has shown and described the basic principles, main features, and characteristics of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model includes the appended claims and their equivalents.
