[0043] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean that they are necessary sequences, unless it is stated that a certain sequence must be followed.

[0044] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The terms "connection" and "coupling" used in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0045] In one embodiment, please refer to Figures 1 to 3 , the air purifier includes a main body 1, a fan 2, a filtering device (not shown in the figure), a cover 4 and a top cover 3. Among them, a purification chamber 11 is provided inside the main body 1, and the main body 1 is provided with an air inlet 12 and an air outlet 13 that communicate with the purification chamber 11. The fan 2 is arranged inside the purification chamber 11 and is used to make air enter the purification chamber 11 from the air inlet 12 and flow out from the air outlet 13. The filtering device is arranged inside the purification chamber 11 for filtering air. In one embodiment, the filtering device can adopt any feasible filter element type, such as a filter net, a paper filter element, an activated carbon filter element, etc.

[0046] The cover 4 is arranged on the top of the main body 1, and a guiding structure 40 is provided on the periphery of the cover 4. The guiding structure 40 has a guiding surface 41, and the guiding surface 41 is used to guide the air flowing out from the air outlet 13 to flow toward the periphery of the cover 4.

[0047] The top cover 3 is arranged on the top of the cover 4. The top cover 3 is used to carry household items, so that the top cover 3 can be used as a tabletop for placing various household items, such as books, wallets, keys, etc. In one embodiment, the top cover can be circular or oval.

[0048] During the purification process, the air purifier of the present application can be used as a table to place various household items, enriching the functions of the air purifier.

[0049] Specifically, in one embodiment, please refer to Figure 1 and Figure 3 , the air outlet 13 opens upward, and the guiding surface 41 is located above the air outlet 13. The guiding surface 41 is used to guide the air flowing out from the air outlet 13 to flow around the cover 4.

[0050] Further, in one embodiment, a light-emitting component is provided inside the cover body 4. At least part of the guiding structure 40 is made of a light-transmitting material. The air purifier includes an air quality detection structure for detecting the surrounding air quality. In one embodiment, the air quality detection structure uses an air quality sensor. The light-emitting component is connected to the air quality detection structure and is configured to emit different colors of light through the guiding surface according to the air quality detected by the air purifier. With the different colors of light emitted by the general light-emitting component, users can perceive the surrounding air quality based on the light, thereby controlling the operating time of the air purifier or the speed of the fan, which is beneficial for saving electric energy and better purifying the air to improve air quality. For example, when the light-emitting component emits blue light, it indicates that the surrounding air quality is good. At this time, the speed of the fan can be reduced or the operating time can be shortened to save electric energy. When the light-emitting component emits yellow light, it indicates that the surrounding air quality is average. At this time, the speed of the fan can be slightly increased or the operating time can be slightly extended to purify the air. When the light-emitting component emits red light, it indicates that the surrounding air quality is poor. At this time, the speed of the fan can be increased or the operating time can be extended to better purify the air. The color of the light emitted by the light-emitting component according to the surrounding air quality can be set according to the user's preference.

[0051] In one embodiment, the entire guiding structure 40 is made of a light-transmitting material. In another embodiment, a part of the guiding structure 40 is made of a light-transmitting material, and another part is made of an opaque material. For example, the guiding structure includes light-transmitting strips and light-blocking strips, which are alternately arranged.

[0052] Further, in one embodiment, the light-emitting component is an LED lamp. Please refer to Figure 1 and Figure 3 , the guiding structure 40 is in a bowl shape, and the cross-sectional area of the lower part of the guiding structure 40 is smaller than that of the upper part. When the light-emitting component emits different colors of light, the guiding structure 40 forms a bowl-shaped lamp body. Specifically, the guiding structure 40 is entirely made of a light-transmitting material, and this light-transmitting material can be a transparent or translucent plastic material or a glass material. When the LED lamp emits different colors of light, the bowl-shaped lamp body formed by the guiding structure 40 facilitates users to quickly perceive the surrounding air quality detected by the air purifier in the home environment. In one embodiment, in addition to the bowl shape, the guiding structure 40 can also be in a hemispherical shape. When the light-emitting component emits different colors of light, the guiding structure 40 forms a hemispherical lamp body.

[0053] Further, in one embodiment, please refer to Figure 1 and Figure 3 , the top cover 3 is detachably fixed to the top of the cover body 4. By designing the top cover 3 to be detachable, users can, according to their own needs, install top covers 3 of different sizes to meet the needs of placing various sizes of household items.

[0054] Further, in one embodiment, please refer to Figure 3 and Figure 4 , the cover body 4 is provided with a first clamping structure 42, and the top cover 3 is provided with a second clamping structure 31. The first clamping structure 42 and the second clamping structure 31 can be clamped to prevent the top cover 3 from rotating relative to the cover body 4 or to prevent the top cover 3 from separating from the cover body 4. The cover body 4 and the top cover 3 are detachably fixed by clamping, which is convenient for disassembly and assembly. Specifically, in one embodiment, the top cover 3 and the cover body 4 are directly fixed together through the first clamping structure 42 and the second clamping structure 31, and the top cover 3 and the cover body 4 cannot be separated. In one embodiment, please refer to Figures 4 to 6 , after the top cover 3 and the cover body 4 are rotationally buckled, the first clamping structure 42 and the second clamping structure 31 are clamped to prevent the top cover 3 from rotating relative to the cover body 4. In this way, the top cover 3 and the cover body 4 cannot rotate relative to each other and cannot be separated.

[0055] In addition to the detachable fixation by the above-mentioned clamping structure between the top cover 3 and the cover body 4, in some other embodiments, the top cover 3 can also be fixed to the cover body 4 by fasteners (such as screws), or can also be magnetically fixed to the cover body 4.

[0056] Regarding the form of rotational buckling between the top cover 3 and the cover body 4, in one embodiment, please refer to Figure 5 and Figure 6 , the top cover 3 has a rotating clamping block 32, and the cover body 4 has a rotating clamping groove 43 adapted to the rotating clamping block 32. Rotating the top cover 3 relative to the cover body 4 in the first direction can make the rotating clamping block 32 and the rotating clamping groove 43 be clamped together. The first clamping structure 42 and the second clamping structure 31 can be clamped to prevent the top cover 3 from rotating relative to the cover body 4 in the second direction opposite to the first direction. In addition to the above form, in another embodiment, the top cover 3 has a rotating clamping groove 43, and the cover body 4 has a rotating clamping block 32 adapted to the rotating clamping groove 43. Rotating the top cover 3 relative to the cover body 4 in the first direction can make the rotating clamping block 32 and the rotating clamping groove 43 be clamped together. The first clamping structure 42 and the second clamping structure 31 can be clamped to prevent the top cover 3 from rotating relative to the cover body 4 in the second direction opposite to the first direction, thereby preventing the rotating clamping block 32 from separating from the rotating clamping groove 43.

[0057] Regarding the form of the first clamping structure 42 and the second clamping structure 31, in one embodiment, please refer to Figure 3 and Figure 4 , the first clamping structure 42 includes a clamping block 423, and the second clamping structure 31 includes a clamping groove 310 that cooperates with the clamping block 423. In another embodiment, the first clamping structure 42 includes a clamping member, the clamping member is movably arranged on the cover body, the clamping member has a clamping groove, and the second clamping structure 31 includes a clamping block that cooperates with the clamping groove, and the clamping block is fixed on the top cover.

[0058] The snap block and the snap groove are rotationally locked, and the cross-section of the snap block is non-circular. Specifically, the cross-sectional shape of the snap block can be a T-shape, an oval, a polygon, or an irregular special shape, etc., and any other feasible shape. Similarly, the snap groove 310 can also be a T-shape, an oval, a polygon, or an irregular special shape, etc., and any other feasible shape.

[0059] In one embodiment, please refer to Figure 3 and Figure 4 , the first snap structure 42 is provided on the cover 4 and can move relative to the cover 4. During the movement stroke of the first snap structure 42, there are a snap position and a release position. At the snap position, the first snap structure 42 snaps onto the second snap structure 31 to prevent the top cover 3 from rotating relative to the cover 4 or to prevent the top cover 3 from separating from the cover 4. At the release position, the first snap structure 42 releases the snap action on the second snap structure 31. In this way, by moving the first snap structure 42, the action between the first snap structure 42 and the second snap structure 31 can be released. In some other embodiments, in addition to being movably provided on the cover 4, the first snap structure 42 can also be fixed on the cover 4. For example, the first snap structure 42 includes an elastic hook, and the second snap structure 31 has a slot adapted to the elastic hook. After the first snap structure 42 snaps onto the second snap structure 31, the elastic hook snaps into the slot of the second snap structure 31 to restrict the separation of the top cover 3 from the cover 4. When the top cover 3 needs to be removed, by forcibly removing the top cover 3, the elastic hook can be deformed and separated from the slot.

[0060] In one embodiment, please refer to Figure 3 and Figure 4 , the air purifier includes a first elastic member 44, and the first elastic member 44 is used to apply an elastic force to the first snap structure 42 to keep the first snap structure 42 in the snap position. By means of the first elastic member 44, the stability of the connection between the first snap structure 42 and the second snap structure 31 can be higher after they are snapped together. In one embodiment, the first elastic member 44 is a spring. In one embodiment, when the first snap structure 42 moves towards the release position, the first elastic member 44 is compressed, and the elastic force of the first elastic member 44 on the first snap structure 42 increases. When the first snap structure 42 moves from the release position towards the snap position, the compression amount of the first elastic member 44 decreases, and the elastic force on the first snap structure 42 decreases.

[0061] In some other embodiments, the first elastic member 44 can also be a spring piece, an elastic block, etc.

[0062] In one embodiment, in order to facilitate the release of the snap action of the first snap structure 42, please refer to Figure 7 and Figure 8, the air purifier includes a latching release member 45 for releasing the latching effect of the first latching structure 42. The latching release member 45 is movably installed on the cover 4, and the latching release member 45 has an exposed release operation portion 451. By operating the release operation portion 451, the latching effect of the first latching structure 42 on the second latching structure 31 can be released. It is more convenient to operate the first latching structure 42 through the latching release member 45. In some other embodiments, in addition to using the latching release member 45, other tools can also be used to operate the first latching structure 42. Of course, the first latching structure 42 can also be an elastic structure. When a relatively large force is applied to the top cover 3 (such as by prying or leaving a disassembly handle on the top cover 3), the first latching structure 42 can be deformed, thereby releasing the latching effect between the first latching structure 42 and the second latching structure 31.

[0063] In one embodiment, please refer to Figure 4 , both the first latching structure 42 and the latching release member 45 can be movably assembled on the cover 4, and the moving direction of the first latching structure 42 and the moving direction of the latching release member 45 form an angle of 30 degrees to 150 degrees. Specifically, in one embodiment, please refer to Figure 4 , the moving direction of the first latching structure 42 and the moving direction of the latching release member 45 form an angle of 90 degrees. In some other embodiments, the angle between the moving direction of the first latching structure 42 and the moving direction of the latching release member 45 can be any feasible angle such as 30 degrees, 60 degrees, 120 degrees or 150 degrees.

[0064] In one embodiment, please refer to Figure 9 and Figure 10 , the first latching structure 42 has a first guiding slope 421, and the latching release member 45 applies a force to the first latching structure 42 by pushing against the first guiding slope 421, causing the first latching structure 42 to move away from the latching position to the release position. The latching release member 45 has a second guiding slope 452, and the latching release member 45 applies a force to the first latching structure 42 by pushing against the first latching structure 42 through the second guiding slope 452, causing the first latching structure 42 to move away from the latching position to the release position. The first guiding slope 421 of the first latching structure 42 contacts the second guiding slope 452 of the latching release member 45, and the latching release member 45 generates a component force that causes the first latching structure 42 to move towards the release position. Through the action of the first guiding slope 421 and the second guiding slope 452, the latching release member 45 with a moving direction different from that of the first latching structure 42 can push the first latching structure 42 to move, facilitating the layout of the latching release member 45 and the first latching structure 42.

[0065] In one embodiment, the latching release member 45 does not have the second guiding slope 452. The first guiding slope 421 of the first latching structure 42 contacts the latching release member 45. Under the guiding effect of the first guiding slope 421 of the first latching structure 42, the force exerted by the latching release member 45 on the first latching structure 42 can generate a component force that causes the first latching structure 42 to move towards the release position. In another embodiment, the first latching structure 42 does not have the first guiding slope 421. The second guiding slope 452 of the latching release member 45 contacts the first latching structure 42. Under the action of the second guiding slope 452, a component force that causes the first latching structure 42 to move towards the release position can be generated.

[0066] Specifically, in one embodiment, please refer to Figure 9 and Figure 10 , the first guiding slope 421 and / or the second guiding slope 452 is an inclined surface. In some other embodiments, in addition to being an inclined plane, the first guiding slope 421 and the second guiding slope 452 can also be guiding surfaces of other shapes, such as convex surfaces, concave surfaces, etc.

[0067] In one embodiment, please refer to Figure 9 and Figure 10 , the air purifier includes a second elastic member 46. The second elastic member 46 provides an elastic resistance when the latching release member 45 pushes against the first latching structure 42. The second elastic member 46 facilitates maintaining the position of the latching release member 45. Under the action of the second elastic member 46, when it is not necessary for the latching release member 45 to push against the first latching structure 42, the latching release member 45 can be conveniently reset. In one embodiment, the second elastic member 46 is a spring. In one embodiment, please refer to Figure 4 , Figure 9 and Figure 10 , when the latching release member 45 moves in the third direction to push against the first latching structure 42, the second elastic member 46 is compressed, and the elastic force of the second elastic member 46 on the latching release member 45 increases. When the latching release member 45 moves in the fourth direction for reset, the compression amount of the second elastic member 46 decreases, and the elastic force on the latching release member 45 decreases, where the third direction is opposite to the fourth direction. In some other embodiments, the second elastic member 46 can also be a spring piece or an elastic block.

[0068] In one embodiment, please refer to Figure 4 , Figure 9 and Figure 10 , both the first elastic member 44 and the second elastic member 46 are springs, and the extending direction of the first elastic member 44 is perpendicular to the extending direction of the second elastic member 46.

[0069] After the latching effect between the first latching structure 42 and the second latching structure 31 is released by the latching release member 45, if the latching release member 45 immediately resets, the first latching structure 42 will also reset and latch with the second latching structure 31 again, which is not convenient for separating the top cover 3 from the cover body 4. To facilitate the separation of the top cover 3 from the cover body 4, in one embodiment, please refer to Figure 4 、 Figure 9 and Figure 10 , the first latching structure 42 includes a first stopping portion 422, and the latching release member 45 includes a second stopping portion 453. After the latching release member 45 pushes the first latching structure 42 to move to the release position, the first stopping portion 422 and the second stopping portion 453 are in a stopping cooperation in the moving direction of the latching release member 45 to prevent the latching release member 45 from resetting under the action of the second elastic member 46. The latching release member 45 and the first latching structure 42 are stopped in the moving direction of the first latching structure 42. Under the action of the latching release member 45, the first latching structure 42 can be prevented from moving towards the latching position. In this way, the first latching structure 42 can be maintained in the release position, facilitating the separation operation of the top cover 3 and the cover body 4.

[0070] Further, in one embodiment, please refer to Figure 4 、 Figure 9 and Figure 10 , the second stopping portion 453 is a stopping protrusion. After the latching release member 45 pushes the first latching structure 42 to move to the release position, the latching release member 45 is subjected to the elastic force of the second elastic member 46 that causes the latching release member 45 to reset. However, due to the stopping between the second stopping portion 453 and the first stopping portion 422 in the moving direction of the latching release member 45, the latching release member 45 cannot reset, and the first latching structure 42 is maintained in the release position.

[0071] In one embodiment, please refer to Figure 4 、 Figure 9 and Figure 10 , when the first latching structure 42 and the latching release member 45 are stopped to maintain the first latching structure 42 in the release position, after applying a force to the first latching structure 42 to make the first latching structure 42 continue to move in a direction away from the latching position, the first stopping portion 422 and the second stopping portion 453 are disengaged from the stopping cooperation.

In one embodiment, as Figure 8 shown, the fixing plate 48 has a limiting portion 482, and the limiting portion 482 limits the clamping release member 45 so that the clamping release member 45 moves horizontally and cannot move upward.

[0079] In one embodiment, please refer to Figures 1 to 11 , when it is necessary to remove the top cover 3, press the release operation portion 451 of the clamping release member 45 to make the clamping release member 45 push against the first clamping structure 42, so that the first clamping structure 42 moves downward until the second stop portion 453 on the clamping release member 45 engages with the first stop portion 422 for stopping, so that the clamping release member 45 maintains its position. The clamping release member 45 and the first clamping structure 42 are engaged with each other up and down to keep the first clamping structure 42 in the release position. The first clamping structure 42 is disengaged from the second clamping structure 31, and the top cover 3 can be rotated in the second direction. Rotate the top cover 3 in the second direction so that the rotation catch 32 on the top cover 3 disengages from the rotation slot 43. During this process, the abutting portion 33 on the top cover 3 abuts downward against the first clamping structure 42, so that the first stop portion 422 and the second stop portion 453 are disengaged from the stop. The clamping release member 45 is reset under the elastic force of the second elastic member 46, and the first clamping structure 42 is separated from the second clamping structure 31, realizing the unlocking of the top cover 3.

[0080] When installing the top cover 3, place the top cover 3 on the top of the cover body 4, and then rotate the top cover 3 in the first direction so that the rotating block 32 on the top cover 3 is inserted into the rotating slot 43. During this process, when the resistance part 33 moves to the position of the first clamping structure 42, it pushes the first clamping structure 42 to make the first clamping structure 42 move downward until the resistance part 33 leaves the position of the first clamping structure 42. After the second clamping structure 31 moves to the position of the first clamping structure 42, the first clamping structure 42 is reset under the action of the first elastic member 44 and is clamped with the second clamping structure 31. In this way, the top cover 3 cannot be rotated in the second direction, and the rotating block 32 cannot be separated from the rotating slot 43, thereby achieving the fixation of the top cover 3 and the cover body 4.
