The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0025] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0027] The embodiment of the utility model provides an air purifier back cover which is easy to disassemble and assemble. Figure 1-5 As shown, it includes a cover body 100, and a plurality of first ridges 210 are arranged on the top of the rear side surface of the cover body 100 (the side close to the air purifier, and the side exposed to the outside is the front side surface of the cover body 100), all of the first ridges 210 can be at the same height, and adjacent first ridges 210 can be spaced a certain distance apart, and the side of the first ridge 210 away from the cover body 100 (i.e., the side protruding outward) is connected with a first stop bar 220 extending upward, and the first stop bar 220 can be integrally connected with the first ridge 210, and the cross-sectional shape of the first stop bar 220 and the first ridge 210 can be "L"-shaped, and a first mounting groove 201 is formed between the first stop bar 220 and the cover body 100.

[0028] A plurality of second ridges 310 are provided at the bottom of the rear side surface of the cover body 100. All the second ridges 310 may be at the same height. Adjacent second ridges 310 may be spaced a certain distance apart. A second stop 320 extending downward is connected to the side of the second ridge 310 away from the cover body 100. The second stop 320 may be integrally connected to the second ridge 310. The cross-sectional shape of the second stop 320 and the second ridge 310 may be "L"-shaped. A second mounting groove 301 is formed between the second stop 320 and the cover body 100.

[0029] like Figure 5 As shown, an upper convex edge 510 and a lower convex edge 520 can be provided on the shell structure of the air purifier. When installing the back cover of this embodiment, the upper convex edge 510 is obliquely inserted into the first mounting groove 201, and then the back cover is lifted upward so that the lower convex edge 520 can be aligned with the second mounting groove 301. Then the back cover is lowered, and the upper convex edge 510 and the lower convex edge 520 on the air purifier are respectively inserted into the first mounting groove 201 and the second mounting groove 301. Under the action of the back cover's own weight, the upper convex edge 510 is not easy to be removed from the first mounting groove 201. 01, the lower convex edge 520 is not easy to come out of the second mounting groove 301, that is, the installation of the rear cover is completed; when removing the rear cover, lift the rear cover obliquely upward to make the lower convex edge 520 on the air purifier disengage from the second mounting groove 301, and then move the rear cover obliquely downward to make the upper convex edge 510 on the air purifier disengage from the first mounting groove 201, and the rear cover is removed from the air purifier. Compared with the traditional installation method, the installation and disassembly of the rear cover of this embodiment are easier, which is convenient for the inspection and maintenance of the air purifier.

[0030] At the same time, the rear side of the cover body 100 is also provided with a plurality of positioning structures 400 for limiting the lateral movement of the cover body 100, and the shell structure is provided with a corresponding alignment structure, which is assembled with the positioning structure 400 to position the cover body 100. In this way, the cover body 100 will not move laterally relative to the shell structure, making the installation of the rear cover more stable.

[0031] In some embodiments, the first stop bar 220 is provided with a first inclined surface 221 at the top of the inner side surface close to the cover body 100, and the first inclined surface 221 gradually moves away from the cover body 100 in the direction of upward extension; the second stop bar 320 is provided with a second inclined surface at the bottom of the inner side surface close to the cover body 100, and the second inclined surface gradually moves away from the cover body 100 in the direction of downward extension. The setting of the first inclined surface 221 and the second inclined surface is equivalent to increasing the opening width of the first installation groove 201 and the second installation groove 301. When the cover body 100 is set obliquely, the convex edge is easier to insert into or disengage from the installation groove.

[0032] In some embodiments, the bottom of the first ridge 210 and the top of the second ridge 310 are both provided with reinforcing ribs 110 connected to the cover body 100 to enhance the structural strength of the first ridge 210 and the second ridge 310, thereby preventing the first ridge 210 and the second ridge 310 from being deformed or damaged due to long-term stress.

[0033] Furthermore, a connecting strip 120 is provided between at least two adjacent first convex strips 210, and the two ends of the connecting strip 120 are respectively connected to the reinforcing ribs 110 at the bottom of the two adjacent first convex strips 210. The connecting strip 120 can be fixed on the cover body 100, and the structural strength of the reinforcing rib 110 is enhanced by the connecting strip 120, thereby enhancing the supporting effect on the first convex strips 210. For some locations with large local forces, the connecting strip 120 of this embodiment can be used.

[0034] In some embodiments, a notch 101 is provided at the bottom of the front side of the cover body 100, and the user's fingers can be inserted into the notch 101 to lift the entire back cover upwards, which is more labor-saving to operate and does not require the user to pry up the bottom edge of the cover body 100, thereby facilitating the removal of the lower back cover.

[0035] In some embodiments, the positioning structure 400 includes a hook 410, and the hook 410 includes a hook seat 411 disposed on the rear side of the cover body 100 and a hook head 412 connected to the hook seat 411, and the hook head 412 is located on the top of the hook seat 411 and extends upward. The housing structure may be provided with a hook groove adapted to the hook 410. When the rear cover is installed, the hook 410 is hooked upward in the hook groove to limit the lateral movement of the entire cover body 100 to the left or right, thereby improving the stability of the rear cover.

[0036] Furthermore, the positioning structure 400 also includes a positioning block 420, and the rear side of the positioning block 420 is provided with a positioning groove 421 extending in the vertical direction. A corresponding positioning plate can be provided on the shell structure. When the back cover is installed, the positioning plate is inserted into the positioning groove 421 to limit the lateral movement of the entire cover body 100 to the left or right side, thereby further improving the stability of the back cover.

[0037] In some embodiments, the reinforcing ribs 110, connecting strips 120, first ridges 210, first stop strips 220, second ridges 310, second stop strips 320, hooks 410 and positioning blocks 420 of the above embodiments can all be integrally connected to the cover body 100 so as to be integrally formed through an injection molding process, thereby facilitating the manufacture of the entire back cover.
