Description

Technical Field

[0001] The utility model belongs to the technical field of air purification equipment, and specifically relates to an air purification dust collecting structure which is easy to replace. Background Art

[0002] Air purification refers to providing overall solutions for various indoor environmental problems, such as sterilization and disinfection, dust reduction and haze removal, removal of harmful decoration residues and odors, etc., to improve living and office conditions and enhance physical and mental health. After the air purifier has been used for a period of time, the internal filter element generally needs to be replaced.

[0003] In order to improve the convenience of replacing the filter element, the existing air purifiers generally adopt a design in which the filter element is inserted into the plug-in slot and fixed by a snap mechanism. However, it is often difficult to ensure a complete seal between the filter element and the plug-in slot by relying solely on the snap mechanism, which affects the use effect and performance of the air purifier to a certain extent. On the other hand, if bolt fixing is used instead, although the sealing can be improved, it will undoubtedly make the installation and removal process of the filter element relatively cumbersome and laborious, increasing the user's difficulty of use and maintenance costs.

It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0021] like Figure 1-3As shown, an air purification and dust collection structure that is easy to replace includes an air purifier 1, an air inlet slot 2 is provided on one side of the air purifier 1, an air inlet grid is provided on the inner side of the air inlet slot 2, an electric fan 3 is provided on the inner side of the air inlet slot 2 and on one side of the air inlet grid, a filter slot 4 connected to the air inlet slot 2 is provided on the other side of the air purifier 1, a first extrusion component is provided on the inner side of the filter slot 4, a plurality of dust filter plates 9 close to each other are provided inside the filter slot 4 and on one side of the first extrusion component, a second extrusion component that can extrude the dust filter plate 9 at the end is provided on the outer wall of the air purifier 1, the structure is simple and the operation is convenient, and the dust filter plate 9 can be installed, fixed and disassembled through the cooperation of the first extrusion component and the second extrusion component. The first extrusion assembly includes a plurality of first plug-in slots 5 on the inner side of the filter slot 4 and are located around the air inlet slot 2. A first plug-in rod 6 is plugged into the interior of the first plug-in slot 5. A first spring 7 is fixed to the inner side of the first plug-in slot 5, and the other end of the first spring 7 is fixed to one end of the first plug-in rod 6. A first extrusion frame 8 is fixed between one ends of the plurality of first plug-in rods 6 and is located in the filter slot 4. A through hole is provided in the middle of the first extrusion frame 8. The first plug-in rod 6 is driven to move by the elastic force of the first spring 7. The first plug-in rod 6 drives the first extrusion frame 8 to move, and the dust collecting filter plate 9 that is tightly attached is squeezed, thereby improving the stability of the dust collecting filter plate 9 being fixed. The first extrusion frame 8 has a certain movable space in the filter slot 4. The second extrusion assembly includes mounting blocks 10 fixed on both sides of the air purifier 1, and a plurality of second plug-in slots 11 are provided on one side of the mounting block 10. A U-shaped plug-in rod 12 is plugged into the second plug-in slot 11, and one end of the U-shaped plug-in rod 12 is located in the second plug-in slot 11 and is fixed with a second spring 13. A U-shaped extrusion frame 14 is fixed in the filter slot 4 between the other ends of the plurality of U-shaped plug-in rods 12. The outer wall of the U-shaped extrusion frame 14 is pressed tightly against the outer wall of the dust collecting filter plate 9 at the end. A baffle is provided at the bottom of the U-shaped extrusion frame 14, and an inclined slide plate 15 is provided at the top of the U-shaped extrusion frame 14, and the top of the inclined slide plate 15 extends to the outside of the filter slot 4. The tension of the second spring 13 pulls the U-shaped plug-in rod 12 to one side, and then drives the U-shaped extrusion frame 14 to squeeze the dust filter plate 9 at the end through the U-shaped plug-in rod 12, thereby improving the stability of the dust filter plate 9 fixation. The inclined slide plate 15 is provided, and when the dust filter plate 9 is installed, the bottom of the dust filter plate 9 can be vertically pressed against the outer wall of the inclined slide plate 15 and pressed downward, thereby driving the U-shaped extrusion frame 14 to move to one side, and the dust filter plate 9 is pressed until it contacts the baffle, and the pressing is stopped. The U-shaped extrusion frame 14 is reset by the tension of the second spring 13, and the dust filter plate 9 is squeezed and fixed. The elastic force of the second spring 13 is greater than the elastic force of the first spring 7, so that the U-shaped extrusion frame 14 can overcome the elastic force of the first spring 7 and reset normally;

[0022] like Figure 2 As shown, a sealing rubber ring is provided on one side of the plurality of dust collecting filter plates 9 and facing the first extrusion frame 8, which increases the sealing performance of the connection of the plurality of dust collecting filter plates 9 and facilitates the normal use of the device;

[0023] like Figure 2 As shown, the outer wall of the first extrusion frame 8 is sealed and slidably connected to the inner wall of the filter tank 4, and a second sealing ring is provided on the outer wall of the first extrusion frame 8, and the second sealing ring is sealed and slidably connected to the inner wall of the filter tank 4, thereby increasing the sealing performance of the sliding connection between the first extrusion frame 8 and the filter tank 4;

[0024] like Figure 1-2 As shown, a handle groove 17 is provided on the top of one side of the dust collecting filter plate 9, so that the dust collecting filter plate 9 can be easily taken out from the filter tank 4 through the handle groove 17;

[0025] like Figure 1-2 As shown, positioning plates 16 are provided on the outer wall of the air purifier 1 and on both sides of the filter slot 4, and a limiting plate is provided on one side of the positioning plate 16. The top view cross-section of the positioning plate 16 and the limiting plate is L-shaped, which facilitates the dust collecting filter plate 9 to be smoothly inserted into the filter slot 4, which is more practical.

[0026] The working principle of the utility model is as follows: when in use, when installing the dust filter plate 9, the bottom of the dust filter plate 9 can be vertically pressed against the outer wall of the inclined slide plate 15 and pressed downward, thereby driving the U-shaped extrusion frame 14 to move to one side, and the dust filter plate 9 is pressed until it contacts the baffle, and the pressing is stopped. The U-shaped extrusion frame 14 is reset by the pulling force of the second spring 13, and the first extrusion frame 8 is cooperated to squeeze and fix the dust filter plate 9. The above operation can be repeated for the installation of multiple dust filter plates 9. When disassembling and replacing, the dust filter plate 9 can be pulled toward the outside of the filter slot 4 through the handle slot 17. When the dust filter plate 9 is moved out of the filter slot 4, the dust filter plate 9 is lifted up through the handle slot 17 to take out the dust filter plate 9.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
