[0042] This application provides a rear cover structure, which includes a rear cover 100, wherein the edge of the rear cover 100 is arc-shaped, and the arc-shaped edge of the rear cover 100 covers the connection between the rear cover 100 and the side cover 200, bottom cover 300 and top cover 400 of the air purifier. The rear cover 100 includes a rear upper cover 110 and a rear lower cover 120, the rear upper cover 110 being detachably connected to the side cover 200 and the top cover 400 respectively, and the rear lower cover 120 being detachably connected to the side cover 200 and the bottom cover 300 respectively.

[0043] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the arc-shaped edge of the rear cover 100 covers the connection between the rear cover 100 and the side cover 200, the bottom cover 300 and the top cover 400, thereby reducing the gaps between the connecting parts and improving the overall appearance of the purifier and enhancing its aesthetics. At the same time, the detachable connection between the rear upper cover 110 and the rear lower cover 120 and the side cover 200, the top cover 400 and the bottom cover 300 respectively achieves multi-point fixation, enhancing the connection stability between the rear cover 100 and each component and preventing loosening and falling off.

[0044] In some specific embodiments, the upper rear cover 110 and the lower rear cover 120 are detachably connected. The upper rear cover 110 is integrally provided with a snap-fit ​​structure 101, and the lower rear cover 120 is provided with a first rear buckle block 102. The first rear buckle block 102 passes through the upper rear cover 110 and snaps into the snap-fit ​​structure 101.

[0045] Please see Figure 2and Figure 3 As shown, in this embodiment, two first rear buckle blocks 102 integrally formed with the top of the inner side of the rear lower cover 120 are provided, and the snap-fit ​​structure 101 is provided at the bottom of the inner side of the rear upper cover 110. When the rear upper cover 110 and the rear lower cover 120 need to be connected, the rear lower cover 120 can be moved toward the rear upper cover 110, so that the first rear buckle blocks 102 pass through the housing of the rear upper cover 110 and extend into the snap-fit ​​structure 101, so that the rear lower cover 120 is snapped into the snap-fit ​​structure 101, thereby realizing the connection and fixation of the rear upper cover 110 and the rear lower cover 120.

[0046] In some specific embodiments, the snap-fit ​​structure 101 includes a first spring piece 1011 and a second spring piece 1012 integrally formed with the rear upper cover 110. A through hole 1013 is formed between the first spring piece 1011 and the second spring piece 1012. An avoidance hole 1014 is provided on the rear upper cover 110 at the position of the through hole 1013. The first rear buckle block 102 has a protrusion.

[0047] Please see Figure 2 , Figure 3 as well as Figure 7 As shown, when the upper rear cover 110 and the lower rear cover 120 are snapped together, that is, when the lower rear cover 120 moves toward the upper rear cover 110, the first rear latch 102 passes through the clearance hole 1014 into the through hole 1013. As the lower rear cover 120 moves the first rear latch 102 toward the upper rear cover 110, the protrusion of the first rear latch 102 abuts against the first spring piece 1011 and the second spring piece 1012, causing the through hole 1013 to open and increase its width. During the process of being stretched open, the first spring piece 1011 and the second spring piece 1012 will undergo certain deformation. When the protrusion of the first rear buckle block 102 passes through the through hole 1013, the first spring piece 1011 and the second spring piece 1012 will return to their initial state under their own elastic force, so that the width of the through hole 1013 will also return to its initial state. At this time, the first spring piece 1011 and the second spring piece 1012 will engage with the first rear buckle block 102 located between them, thereby realizing the connection between the rear upper cover 110 and the rear lower cover 120.

[0048] In this embodiment, the cross-section of the first rear latch block 102 first increases and then decreases along its moving direction.

[0049] In some specific embodiments, at least one first insert 111 is provided on the top of the rear upper cover 110, and the first insert 111 is inserted into the top insertion hole 410 at the edge of the top cover 400. Second inserts 112 are provided on both sides of the rear upper cover 110, and the second inserts 112 are inserted into the side buckle positions 210 at the edges of the side covers 200.

Correspondingly, top insertion holes 410 adapted to the number and position of the first inserts 111 are opened at the edge of the upper surface of the top cover 400. After the first inserts 111 are inserted into the top insertion holes 410, the connection between the upper cover 110 and the top cover 400 is completed. Furthermore, in order to connect the rear upper cover 110 to the side covers 200, a plurality of first inserts 111 are integrally provided on the edges of both sides of the rear upper cover 110. Multiple second inserts 112 are formed and set. Side buckle positions 210 corresponding to the second inserts 112 are set at the inner side edge of the side cover 200. Specifically, when the rear upper cover 110 is connected to the top cover 400 and the side cover 200, the first insert 111 is first aligned with the top insertion hole 410 and the second insert 112 is aligned with the side buckle position 210. After moving downward, the upper cover 110 inserts the first insert 111 into the top insertion hole 410 to complete the connection with the top cover 400. At the same time, the second insert 112 is inserted into the side buckle position 210 to complete the connection between the upper cover 110 and the side cover 200.

[0051] Please continue reading. Figure 3 and Figure 8 As shown, the second insert 112 includes a connecting part 1121 connected to the rear upper cover 110. An insertion part 1122 is integrally formed on one side of the connecting part 1121. A limiting groove 1123 is defined between the insertion part 1122 and the connecting part 1121. Correspondingly, the side buckle 210 includes a connecting plate 211 integrally formed with the side cover 200. A first through hole 212 and a second through hole 213 are sequentially formed along the height direction on the connecting plate 211. It should be noted that the opening of the second through hole 213 is smaller than... When the rear upper cover 110 is connected to the side cover 200, in the initial state, the insertion part 1122 is first inserted into the first through hole 212, so that the limiting groove 1123 is aligned with the second through hole 213. As the rear upper cover 110 moves downward, the limiting groove 1123 will move to the position of the second through hole 213. At this time, the connecting plate 211 is located in the limiting groove 1123, completing the snap-fit ​​between the second plug 112 and the side buckle 210, thereby realizing the connection between the rear upper cover 110 and the side cover 200.

[0052] In some specific embodiments, at least one second rear latching block 121 is integrally provided on both sides of the lower rear cover 120, and the second rear latching block 121 is engaged with the side latching block 220 at the edge of the side cover 200.

A second slot 124 is also integrally provided at the bottom of the lower rear cover 120, and the second slot 124 is inserted into a second bottom insertion hole 320 on the side wall of the bottom cover 300.

[0053] Please see Figure 1 , Figure 4 , Figure 5 as well as Figure 7 As shown, in order to fix the rear lower cover 120 to the side cover 200, a plurality of second rear fasteners 121 are integrally formed on the inner side surface of the two sides of the rear lower cover 120 at the edge. Correspondingly, side fasteners 220 adapted to the second rear fasteners 121 are provided at the edge of the inner side surface of the side cover 200. When the second rear fasteners 121 and the side fasteners 220 are engaged, the rear lower cover 120 and the side cover 200 are snapped together. Furthermore, in order to connect the rear lower cover 120 to the side cover 200 and the bottom cover 300, a first bottom insertion hole 310 is opened at the edge of the upper surface of the bottom cover 300. Correspondingly, a second bottom insertion hole 310 is provided on the inner side surface of the rear lower cover 200 at the edge of the side ... The bottom of the inner side of the 120 is integrally formed with a first rear insert 122. In this embodiment, in order to connect the rear lower cover 120 with the side cover 200 and the bottom cover 300, the first rear insert 122 can be inserted into the first bottom insertion hole 310. At this time, the first rear insert 122 and the first bottom insertion hole 310 cooperate to achieve a limit, realizing the insertion connection between the rear lower cover 120 and the bottom cover 300. Then, with the first rear insert 122 as the rotation center, the rear lower cover 120 is rotated toward the side cover 200, and then the second rear buckle 121 is inserted into the side buckle 220, thereby realizing the connection between the rear lower cover 120, the bottom cover 300 and the side cover 200.

[0054] In some specific embodiments, the bottom and top of the rear cover 120 are provided with abutment members 123, which abut against the top and bottom of the air purifier filter 500, respectively.
