[0001] The present invention relates to the technical field of purification equipment, and in particular to an air outlet structure of an air purifier and the air purifier. Background Art

[0002] Air purifier, also known as "air cleaner", air freshener, purifier, is a device that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), which can effectively improve the cleanliness of the air.

[0003] In the increasingly competitive air purifier market, the assembly efficiency of the whole machine plays a decisive role in improving the competitiveness of the product. However, the air outlet grille of traditional air purifiers is inconvenient to install, and the air outlet grille and the installation shell are difficult to disassemble after installation, which not only affects the assembly efficiency, but also affects the customer experience, making the product lack of market competitiveness. Summary of the invention

[0005] The specific technical solutions are as follows:

[0006] On the one hand, the present application relates to an air outlet structure of an air purifier, comprising: a mounting shell, the mounting shell being provided with a first limiting portion; and an air outlet grille, the air outlet grille being provided with a second limiting portion, the mounting shell being rotatably disposed on the air outlet grille, when the mounting shell is rotated to a first preset position, the first limiting portion and the second limiting portion are limitedly cooperated, and when the mounting shell is rotated to a second preset position, the first limiting portion and the second limiting portion are separated.

[0007] When the air outlet structure of the above-mentioned air purifier is in use, the mounting shell can be rotated. When the mounting shell is rotated to the first preset position, the first limiting part and the second limiting part are limited and matched. At this time, the first limiting part and the second limiting part can play a role of mutual limitation. Therefore, the mounting shell and the air outlet grille will not jump in the axial direction or the jumping amplitude is very small, thereby realizing the installation of the mounting shell and the air outlet grille; when the mounting shell and the air outlet grille need to be disassembled, it is only necessary to rotate the mounting shell. When the mounting shell is rotated to the second preset position, the mounting shell and the air outlet grille are disassembled and separated. It can be seen that the air outlet structure of the entire air purifier has the advantage of convenient disassembly and assembly.

[0008] The technical solution is further described below:

When the mounting shell is rotated to a first preset position, the first limiting member cooperates with the first limiting portion, and the first limiting member is arranged between the first limiting portion and the outlet of the spiral guide groove.

[0012] In one embodiment, the first limiting member includes a first guide slope, which is inclined along the end of the first limiting member away from the side wall of the air outlet grille toward the side wall of the air outlet grille, and the thickness of the first limiting member gradually increases along the end of the first limiting member away from the side wall of the air outlet grille toward the side wall of the air outlet grille.

[0013] In one of the embodiments, the air outlet grille is further provided with a second limiting member, the second limiting member is spaced apart from the outlet of the spiral guide groove, and the second limiting portion is provided between the second limiting member and the outlet of the spiral guide groove.

[0014] In one embodiment, the first limiting portion is a first clamping portion, and the second limiting portion is a first buckle portion that is clamped and matched with the first clamping portion; or the first limiting portion is a first buckle portion, and the second limiting portion is a first clamping portion that is clamped and matched with the first buckle portion.

[0015] In one embodiment, the air outlet structure of the air purifier also includes an air duct outlet member, the air outlet grille is rotatably disposed on the air duct outlet member, the air duct outlet member is provided with a third limiting portion, and the air outlet grille is provided with a fourth limiting portion. When the air outlet grille is rotated to a third preset position, the third limiting portion and the fourth limiting portion are limitedly cooperated, and when the air outlet grille is rotated to a fourth preset position, the third limiting portion and the fourth limiting portion are separated.

[0016] In one embodiment, the third limiting portion includes a second guide bevel, and the fourth limiting portion includes a third guide bevel that cooperates with the second guide bevel for guiding, and when the air outlet grille rotates to a third preset position, the third limiting portion and the fourth limiting portion are arranged opposite to each other along the axial direction of the air outlet grille, and the height of the third limiting portion along the axial direction of the air outlet grille is higher than the height of the fourth limiting portion along the axial direction of the air outlet grille.

[0017] In one embodiment, the third limiting portion is a second clamping portion, and the fourth limiting portion is a second buckle portion that is clamped and matched with the second clamping portion; or the third limiting portion is a second buckle portion, and the fourth limiting portion is a second clamping portion that is clamped and matched with the second buckle portion.

[0018] On the other hand, the present application also relates to an air purifier, including an air outlet structure of the air purifier.

[0019] When the above-mentioned air purifier is in use, the mounting shell can be rotated. When the mounting shell is rotated to the first preset position, the first limiting part and the second limiting part are limited and matched. At this time, the first limiting part and the second limiting part can play a role of mutual limitation. Therefore, the mounting shell and the air outlet grille will not jump in the axial direction or the jumping amplitude is very small, thereby realizing the installation of the mounting shell and the air outlet grille; when the mounting shell and the air outlet grille need to be disassembled, it is only necessary to rotate the mounting shell. When the mounting shell is rotated to the second preset position, the mounting shell and the air outlet grille are disassembled and separated. It can be seen that the air outlet structure of the entire air purifier has the advantage of convenient disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figures 1 to 4 As shown, an air outlet structure 10 of an air purifier in one embodiment includes: a mounting shell 100, the mounting shell 100 is provided with a first limiting portion 110; and an air outlet grille 200, the air outlet grille 200 is provided with a second limiting portion 210, the mounting shell 100 is rotatably disposed on the air outlet grille 200, when the mounting shell 100 is rotated to a first preset position, the first limiting portion 110 and the second limiting portion 210 are limitedly matched, when the mounting shell 100 is rotated to a second preset position, the first limiting portion 110 and the second limiting portion 210 are separated.

[0032] When the air outlet structure 10 of the air purifier is in use, the mounting shell 100 can be rotated. When the mounting shell 100 is rotated to the first preset position, the first limiting portion 110 and the second limiting portion 210 are limited and matched. At this time, the first limiting portion 110 and the second limiting portion 210 can play a role of mutual limitation. Therefore, the mounting shell 100 and the air outlet grille 200 will not jump in the axial direction or the jumping amplitude is very small, thereby realizing the installation of the mounting shell 100 and the air outlet grille 200; when the mounting shell 100 and the air outlet grille 200 need to be disassembled, it is only necessary to rotate the mounting shell 100. When the mounting shell 100 is rotated to the second preset position, the mounting shell 100 and the air outlet grille 200 can be disassembled and separated. It can be seen that the air outlet structure 10 of the entire air purifier has the advantage of convenient disassembly and assembly. It is necessary to point out that when the mounting shell 100 is rotated to the first preset position, the first limiting portion 110 and the second limiting portion 210 can be limitedly matched. At this time, the first limiting portion 110 can be located above the second limiting portion 210 or the second limiting portion 210 is located above the first limiting portion 110. The first limiting portion 110 and the second limiting portion 210 can be arranged at intervals or in contact with each other, as long as the first limiting portion 110 and the second limiting portion 210 can be limitedly matched when the mounting shell 100 is rotated to the first preset position.

[0033] like Figure 1 and Figure 2As shown, on the basis of the above embodiment, the air outlet grille 200 is provided with a guide structure, and the first limit portion 110 is guided and matched with the guide structure. In this way, the first limit portion 110 moves along the extension direction of the guide structure, so that the first limit portion 110 can accurately move to the first preset position, which is convenient for installing the housing 100 and the air outlet grille 200. On the basis of this embodiment, the guide structure includes a spiral guide groove 220 guided and matched with the first limit portion 110, and the second limit portion is arranged at the outlet of the spiral guide groove 220. In this way, when the installation housing 100 rotates clockwise, the spiral direction of the spiral guide groove 220 is consistent with the rotation direction of the installation housing 100, so that the first limiter 110 can rotate clockwise along the spiral guide groove 220; when the installation housing 100 rotates counterclockwise, the spiral direction of the spiral guide groove 220 is consistent with the rotation direction of the installation housing 100, so that the first limiter 110 can rotate counterclockwise along the spiral guide groove 220. The first limiter 110 is arranged in the spiral guide groove 220, and the spiral guide groove 220 can play a limiting role, and to a certain extent limit the axial runout of the installation housing 100 along the air outlet grille 200. In this embodiment, the inlet 222 of the spiral guide groove is close to the air outlet end of the air outlet grille 200, and the second limiter 210 is arranged at the outlet 224 of the spiral guide groove.

[0034] like Figure 1 and Figure 2As shown, further, on the basis of any of the above embodiments, the air outlet grille 200 is further provided with a first stopper 230, and the first stopper 230 is arranged at the outlet 224 of the spiral guide groove. When the mounting housing 100 rotates to the first preset position, the first stopper 230 and the first stopper 110 are limitedly matched, and the first stopper 230 is arranged between the first stopper 110 and the outlet 224 of the spiral guide groove. In this way, by providing the first stopper 230, the first stopper 110 is prevented from entering the spiral guide groove 220 along the outlet 224 of the spiral guide groove and moving axially. In this way, the stability of the installation of the mounting housing 100 and the air outlet grille 200 is improved. In this embodiment, the first stopper 230 is a stopper protrusion. On the basis of this embodiment, the first stopper 230 includes a first guide slope, and the first guide slope is inclined along the end of the first stopper 230 away from the side wall of the air outlet grille 200 toward the side wall of the air outlet grille 200, and the thickness of the first stopper 230 gradually increases along the end of the first stopper 230 away from the side wall of the air outlet grille 200 toward the side wall of the air outlet grille 200. In this way, by setting the first guide slope, it is convenient to move the mounting housing 100. In this embodiment, the first stopper 230 includes two first guide slopes, and the two first guide slopes are inclined along the end of the first stopper 230 away from the side wall of the air outlet grille 200 toward the side wall of the air outlet grille 200, and the thickness of the first stopper 230 gradually increases along the end of the first stopper 230 away from the side wall of the air outlet grille 200 toward the side wall of the air outlet grille 200, so that the guiding direction of the two first guide slopes is adapted to the rotation direction of the mounting housing 100.

[0035] like Figure 1 and Figure 2 As shown, on the basis of any of the above embodiments, the air outlet grille 200 is further provided with a second stopper 240, the second stopper 240 is spaced apart from the outlet 224 of the spiral guide groove, and the second stopper 210 is provided between the second stopper 240 and the outlet 224 of the spiral guide groove. In this way, by providing the second stopper 240, the rotation range of the mounting housing 100 is limited. When the mounting housing 100 rotates to the first preset position, the first stopper 110 can be between the second stopper 240 and the first stopper 230. In this way, the mounting housing 100 is prevented from continuing to rotate, so that the first stopper 110 and the second stopper 210 are separated, affecting the stability of the mounting housing 100 and the air outlet grille 200. In this embodiment, the second stopper 240 is a stopper protrusion.

[0036] On the basis of any of the above embodiments, the first position-limiting portion 110 is a first clamping portion, and the second position-limiting portion 210 is a first buckle portion that is clamped and matched with the first clamping portion; or the first position-limiting portion 110 is a first buckle portion, and the second position-limiting portion 210 is a first clamping portion that is clamped and matched with the first buckle portion. In this way, the installation housing 100 and the air outlet grille 200 are installed by clamping and matching the first clamping portion and the second clamping portion. The clamping of the first position-limiting portion 110 and the second position-limiting portion 210 can be realized by existing technologies, which will not be described in detail here.

[0037] like Figures 2 to 4 As shown, on the basis of any of the above embodiments, the air outlet structure 10 of the air purifier also includes an air duct outlet member 300, the air outlet grille 200 is rotatably arranged on the air duct outlet member 300, the air duct outlet member 300 is provided with a third limiting portion 310, and the air outlet grille 200 is provided with a fourth limiting portion 250. When the air outlet grille 200 rotates to the third preset position, the third limiting portion 310 and the fourth limiting portion 250 are limited and cooperated, and when the air outlet grille 200 rotates to the fourth preset position, the third limiting portion 310 and the fourth limiting portion 250 are separated. In this way, the air outlet grille 200 can be rotated. When the air outlet grille 200 is rotated to the third preset position, the third limiting portion 310 and the fourth limiting portion 250 are limited in the air outlet grille 200. At this time, the third limiting portion 310 and the fourth limiting portion 250 can play a role of mutual limitation. Therefore, the air outlet grille 200 and the air duct outlet member 300 will not jump in the axial direction or the jumping amplitude is very small, thereby realizing the installation of the air outlet grille 200 and the air duct outlet member 300; when the air outlet grille 200 and the air duct outlet member 300 need to be disassembled, it is only necessary to rotate the air outlet grille 200. When the air outlet grille 200 is rotated to the fourth preset position, the air outlet grille 200 and the air duct outlet member 300 are disassembled and separated. It can be seen that the air outlet structure 10 of the entire air purifier has the advantage of convenient disassembly and assembly. It is necessary to point out that when the air outlet grille 200 rotates to the third preset position, the third limiting portion 310 and the fourth limiting portion 250 are limited and matched. At this time, the third limiting portion 310 is located above the fourth limiting portion 250. The third limiting portion 310 and the fourth limiting portion 250 can be arranged at intervals or in contact with each other, as long as the third limiting portion 310 and the fourth limiting portion 250 are limited and matched when the air outlet grille 200 rotates to the third preset position. Figure 4 The arrows in the figure indicate the installation direction of the mounting housing 100, the air outlet grille 200 and the air duct outlet member 300. The mounting housing 100 is the outermost layer, the air duct outlet member 300 is the innermost layer, and the air outlet grille 200 is located between the mounting housing 100 and the air duct outlet member 300. Specifically, the mounting housing 100 may be a decorative ring or a unit housing. In this embodiment, the mounting housing 100 is a decorative ring.

[0038] like Figure 3As shown, on the basis of any of the above embodiments, the third limiting portion 310 includes a second guide bevel 312, and the fourth limiting portion 250 includes a third guide bevel 252 that guides and cooperates with the second guide bevel 312. When the air outlet grille 200 rotates to the third preset position, the third limiting portion 310 and the fourth limiting portion 250 are arranged opposite to each other along the axial direction of the air outlet grille 200, and the height of the third limiting portion 310 along the axial direction of the air outlet grille 200 is higher than the height of the fourth limiting portion 250 along the axial direction of the air outlet grille 200. In this way, through the guiding cooperation of the second guide bevel 312 and the third guide bevel 252, the air outlet grille 200 is facilitated to move to the third preset position, so that the third limiting portion 310 and the fourth limiting portion 250 are arranged relatively to each other along the axial direction of the air outlet grille 200, and the height of the third limiting portion 310 along the axial direction of the air outlet grille 200 is higher than the height of the fourth limiting portion 250 along the axial direction of the air outlet grille 200. In this way, the third limiting portion 310 and the fourth limiting portion 250 are mutually limited to avoid relative displacement of the air outlet grille 200 and the air duct outlet member 300 in the axial direction.

[0039] On the basis of any of the above embodiments, the third limiting portion 310 is the second clamping portion, and the fourth limiting portion 250 is the second buckle portion that is clamped and matched with the second clamping portion; or the third limiting portion 310 is the second buckle portion, and the fourth limiting portion 250 is the second clamping portion that is clamped and matched with the second buckle portion. In this way, the installation of the air duct outlet member 300 and the air outlet grille 200 is achieved through the clamping and matching of the third clamping portion and the fourth clamping portion.

[0040] An air purifier in one embodiment includes an air outlet structure 10 of the air purifier.

[0041] When the above-mentioned air purifier is in use, the mounting shell 100 can be rotated. When the mounting shell 100 is rotated to the first preset position, the first limiting portion 110 and the second limiting portion 210 are limited and matched. At this time, the first limiting portion 110 and the second limiting portion 210 can play a role of mutual limitation. Therefore, the mounting shell 100 and the air outlet grille 200 will not jump in the axial direction or the jumping amplitude is very small, thereby realizing the installation of the mounting shell 100 and the air outlet grille 200; when it is necessary to disassemble the mounting shell 100 and the air outlet grille 200, it is only necessary to rotate the mounting shell 100. When the mounting shell 100 is rotated to the second preset position, the mounting shell 100 and the air outlet grille 200 can be disassembled and separated. It can be seen that the air outlet structure 10 of the entire air purifier has the advantage of convenient disassembly and assembly.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
