Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification device which is convenient for replacing filter plates. Background Art

[0002] An air purifier refers to a product that can absorb, decompose or transform various air pollutants and effectively improve the cleanliness of the air. Currently, household and commercial air purifiers that remove indoor air pollution are the main components of an air purifier. The air purifier is mainly composed of a case shell, filter section, air duct design, motor, power supply, LCD display, etc. The filter section is mainly composed of a filter element, which is also the most technologically advanced part of a modern air purifier. When an air purifier is used for a long time and a large amount of dust accumulates in the filter element, it needs to be replaced regularly by humans to maintain the purification capacity of the air purification device. When replacing the filter element of an existing air purification device, it is often necessary to manually disassemble and open the case before replacing it. This method has many problems.

[0003] For example, a Chinese utility model patent with announcement number CN212383365U discloses an air purification device that is easy to replace filter plates. Although this solution provides convenience for replacing filter plates by arranging a first filter plate frame and a second filter plate frame installed at intervals in the inner cavity of the box body, maintenance personnel need to first open the lock, then open the inspection door, and finally pull out the first filter plate frame and the second filter plate frame from the box body. The operation is very cumbersome, and when a large amount of dust is accumulated in the air purification device after long-term use, it may be very laborious to manually remove the filter plate. Based on this, an air purification device that is easy to replace filter plates is proposed. Utility Model Content

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1-Figure 5 , an air purification device for facilitating replacement of filter plates in the present embodiment comprises a base plate 1, a box body 19 is fixedly connected to the upper side of the base plate 1, vertical slide grooves 10 are provided on both sides of the interior of the box body 19, a filter plate 7 is slidably connected to the inner sides of the two vertical slide grooves 10, a filter plate driving mechanism for moving the filter plate 7 up and down is provided on the lower side of the filter plate 7, a filter plate fixing mechanism for facilitating removal and installation of new and old filter plates 7 is provided on the upper side of the box body 19, an air inlet mechanism for loading indoor air into the box body 19 is provided on one side of the box body 19, and an exhaust mechanism for re-injecting evolved air into the room is provided on the other side of the box body 19.

[0025] The filter plate driving mechanism includes a horizontal slide groove 4 opened on the base plate 1, and a bidirectional threaded rod 3 is rotatably connected to the inner side of the horizontal slide groove 4. Slide blocks 6 that are slidably connected to the inner side of the horizontal slide groove 4 are respectively threadedly sleeved on both sides of the bidirectional threaded rod 3. A slider linkage mechanism that maintains linkage with the filter plate 7 is arranged on the upper side of the two sliders 6, and a slider driving mechanism that makes the two sliders 6 approach or move away from each other is arranged at one end of the bidirectional threaded rod 3.

[0026] The slider linkage mechanism includes No. 1 grooves 5 respectively opened on the upper sides of the two sliders 6, and the inner sides of the two No. 1 grooves 5 are rotatably connected with connecting plates 2 rotatably connected to the lower sides of the filter plates 7. It should be noted that the length of the two connecting plates 2 when placed horizontally is just equal to the width of the box body 19, and the height of the connecting plates 2 when fully standing is sufficient to expose the filter plates 7 outside the box body 19, which is convenient for maintenance personnel to operate.

[0027] Please combine Figure 2 and Figure 5 As shown, the slider driving mechanism includes a No. 2 groove 9 opened on one side of the box body 19. The depth design of the No. 2 groove 9 satisfies the hidden design of the folding crank 8. The inner side of the No. 2 groove 9 is rotatably connected to a rotating arm 17 fixedly connected to one end of the two-way threaded rod 3. One side of the rotating arm 17 is rotatably connected to the folding crank 8. In actual scenarios, an openable and closable flip door can be provided on the outer side of the No. 2 groove 9 to protect the slider driving mechanism.

[0028] The filter plate fixing mechanism includes a sealing groove 13 opened on the upper side of the box body 19, and a sealing plate 14 abutting the upper side of the filter plate 7 is rotatably connected to one side of the sealing groove 13. In order to ensure the sealing performance of the sealing groove 13 and the sealing plate 14, a fluoride sealing gasket can be installed on the inner side of the sealing groove 13 for sealing. A screw hole 11 is opened on one side of the sealing groove 13, and a positioning bolt 15 cooperating with the screw hole 11 is provided at one end of the sealing plate 14. The air intake mechanism includes a fan 16 connected to one side of the box body 19, and the exhaust mechanism includes an air inlet duct 12 connected to the other side of the box body 19.

[0029] The implementation principle of an air purification device that is easy to replace the filter plate in the embodiment of the present application is: open the positioning bolt 15, flip open the sealing plate 14, then open the folding crank 8 outward, rotate it, and drive the two-way threaded rod 3 to rotate, so that the two sliders 6 approach each other, and the two connecting plates 2 will push the filter plate 7 out of the vertical slide groove 10 from below the filter plate 7. The maintenance personnel can remove the ejected filter plate 7, install a new filter plate 7, rotate the folding crank 8 in the opposite direction, and put it back into the box 19.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
