Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to an air purifier installation structure. Background Art

[0002] An air purifier is a device that can absorb, decompose or transform various pollutants (generally including PM2.5, dust, toxic and harmful gases, bacteria, allergens, etc.). It can effectively improve the air cleanliness of the environment in which it is used, and has therefore been widely recognized and welcomed by the market in recent years.

[0003] For example, a Chinese patent with publication number CN104344530A discloses an air purifier, including: a main shell, having a working device mounting surface and a panel mounting surface located on the back of the working device mounting surface; a panel, the inner surface of which is connected to the panel mounting surface; and a rear shell, the inner surface of which is connected to the working device mounting surface, wherein the panel and the panel mounting surface are connected by a variety of connection structures.

[0004] Although the air purifier reduces the use of screws and improves the disassembly efficiency, the air vents opened on the rear shell and the rear shell are an integrated structure. When the air vents need to be cleaned, due to the integrated setting, the entire rear shell needs to be removed before the interior can be cleaned, which is very inconvenient. For this reason, we propose an air purifier installation structure to solve the above problem. Utility Model Content

[0022] Rectangular openings 12 are respectively formed on four sides of the bottom of the housing 1 , and the lower filter plate 2 is clamped in the rectangular openings 12 .

[0023] The fan 9 is powered on and draws air through the air inlet 13 on the top. The air passes through the upper filter 3, which initially filters the air. The air then passes through the fan 9 and enters the purification module 7 from the opening 81. The purification module 7 purifies the air. The purified air is discharged from the lower filter plates 2 on the four sides of the shell 1, thereby achieving the effect of air purification.

[0024] Example 2

[0025] Reference Figure 1-4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment. Specifically, a purification module 7 is provided at the bottom of the shell 1, and the purification module 7 purifies the air entering the shell 1. The bottom edge of the air inlet 13 is fixedly sleeved with a limiting ring 14. The setting of the limiting ring 14 supports and limits the upper filter 3 to prevent the upper filter 3 from falling into the shell 1.

[0026] Specifically, a card slot 11 is provided on the inner wall of one side of the rectangular opening 12, and a card block 21 is fixedly connected to one end of the lower filter plate 2, and the card block 21 is engaged with the card slot 11. When the lower filter plate 2 needs to be cleaned, the housing 1 is lifted, the lower filter plate 2 is pulled out, and the card block 21 is separated from the card slot 11, and the lower filter plate 2 can be taken out, which is convenient for cleaning the lower filter plate 2 separately. At the same time, a straight-line limiting strip can be fixedly connected to the two side ends of the lower filter plate 2, and a straight-line limiting groove is provided on the inner walls of the two sides of the rectangular opening 12. The limiting groove and the limiting strip are slidably engaged, and the lower filter plate 2 is positioned and limited, so as to ensure the tightness of the lower filter plate 2 when it is installed.

[0027] Specifically, a through hole 81 is opened at the bottom of the mounting frame 8, and the fan 9 is powered on to draw air through the air inlet 13 at the top. The air passes through the upper filter 3, and the upper filter 3 preliminarily filters the air. Then the air passes through the fan 9 and then passes through the through hole 81 to enter the purification module 7, and the purification module 7 purifies the air.

[0028] Specifically, the upper filter screen 3 is fixedly sleeved on the mounting ring 31 , and a plurality of slots 32 are provided on the circumference of the mounting ring 31 .

[0029] Specifically, the limit assembly 4 includes a knob 41, a gear 42, a cylindrical cavity 43, a movable cavity 44, a spring 45, a rack 46, and a limit column 47. The cylindrical cavity 43 is opened at the top of the shell 1. A gear 42 is rotatably provided in the cylindrical cavity 43. The gear 42 is fixedly sleeved on the knob 41. The knob 41 is rotatably connected to the top of the shell 1. One side of the gear 42 is meshed and connected to the rack 46. The rack 46 is slidably arranged in the movable cavity 44. The movable cavity 44 is hollow and arranged at the top of the shell 1. One end of the rack 46 is fixedly connected to one end of the spring 45. The other end of the spring 45 is fixedly connected to one side inner wall of the movable cavity 44. The other end of the rack 46 is fixedly connected to the limit column 47. The limit column 47 is plugged into the slot 32.

[0030] When the upper filter 3 needs to be cleaned, the knob 41 of the limit assembly 4 is turned, the knob 41 drives the fixed gear 42 to rotate, the gear 42 drives the meshing rack 46 to move, the rack 46 compresses the spring 45, and the rack 46 simultaneously drives the limit column 47 fixed at the end to move, and the limit column 47 completely disengages from the slot 32 and enters the movable cavity 44, at which time the upper filter 3 can be removed for cleaning, thereby ensuring the cleanliness of the upper filter 3.

[0031] Example 3

[0032] Reference Figure 1-4, which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. When in use, the fan 9 is powered on to work, and air is drawn through the air inlet 13 on the top. The air passes through the upper filter 3, and the upper filter 3 preliminarily filters the air. Then the air passes through the fan 9 and enters the purification module 7 from the through port 81. The purification module 7 purifies the air. The purified air is discharged from the lower filter plates 2 on the four sides of the shell 1 to achieve the effect of air purification. When it is necessary to clean the upper filter 3, the knob 41 of the limit assembly 4 is turned, and the knob 41 drives the fixed gear 42 to rotate, and the gear 42 drives the meshing rack 46 to move, and the rack 46 compresses the spring 45. The rack 46 simultaneously drives the limiting column 47 fixed at the end to move. After the limiting column 47 is completely disengaged from the slot 32, it enters the active cavity 44. At this time, the upper filter screen 3 can be removed for cleaning, thereby ensuring the cleanliness of the upper filter screen 3. When the lower filter plate 2 needs to be cleaned, the shell 1 is lifted, the lower filter plate 2 is pulled out, and the clamping block 21 is disengaged from the clamping slot 11. Then, the lower filter plate 2 can be taken out, which is convenient for cleaning the lower filter plate 2 separately. At the same time, a straight-line limiting strip can be fixedly connected to the two side ends of the lower filter plate 2, and a straight-line limiting groove is opened on the inner walls on both sides of the rectangular opening 12. The limiting groove is slidably engaged with the limiting strip to position and limit the lower filter plate 2, thereby ensuring the tightness of the lower filter plate 2 during installation.
