[0002] As people's living standards improve, their requirements for air quality are getting higher and higher, so the popularity of air purifiers is also increasing. Humidification, as an additional function selling point of air purifiers, is becoming more and more popular among consumers. Generally speaking, air pollution is more serious in the winter in the north, and the climate in the north is particularly dry in winter, so the two functions of purification and humidification need to be used at the same time.

[0003] The humidification component of the existing air purifier includes a bracket and a moisture absorption disk arranged in the bracket. When the motor drives the bracket to rotate, the bracket continuously scoops water and wets the moisture absorption disk. When the air passes through the moisture absorption disk, the air is humidified. In order to reduce costs, it is considered to use a synchronous motor to drive the humidification component to rotate. However, when the synchronous motor is started, the rotation direction of the motor is uncertain, and it may rotate forward or reverse. The existing humidification component can only realize unidirectional rotation to scoop water and wet the moisture absorption disk, so the humidification component may not be able to realize the humidification function normally. Therefore, the current humidification components mostly use asynchronous motors with higher costs. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the humidification component in the prior art can only rotate in one direction to scoop water and wet the desiccant disc, which is not conducive to reducing costs, thereby providing a humidification component that can rotate in two directions to scoop water and wet the desiccant disc and a device with a humidification component.

[0016] The humidifying assembly provided by the present invention is characterized in that when the humidifying assembly is in operation, the rotating frame is arranged in the water tank so that the lower end of the rotating frame contacts the water in the water tank. During the process of the rotating frame rotating according to the first preset direction, the water in the water tank enters the water storage chamber through the water inlet, and then with the rotation of the rotating frame, the water is stored on one side of the water storage chamber. During the process of rotating to the top, the water in the water storage chamber gradually falls into the moisture absorption plate through the water outlet, and soaks the moisture absorption plate.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1

[0031] The humidification component of the existing air purifier includes a bracket and a moisture absorption disk arranged in the bracket. When the motor drives the bracket to rotate, the bracket continuously scoops water and wets the moisture absorption disk. When the air passes through the moisture absorption disk, the air is humidified. In order to reduce costs, it is considered to use a synchronous motor to drive the humidification component to rotate. However, when the synchronous motor is started, the rotation direction of the motor is uncertain, and it may rotate forward or reverse. The existing humidification component can only realize unidirectional rotation to scoop water and wet the moisture absorption disk, so the humidification component may not be able to realize the humidification function normally. Therefore, the current humidification components mostly use asynchronous motors with higher costs.

[0032] For this reason, Figures 1 to 6 As shown, this embodiment provides a humidifying component, which can rotate bidirectionally to scoop water to wet the moisture absorbing disc 1, so that the humidifying component can be driven to rotate by a synchronous motor, thereby reducing costs.

[0033] In one embodiment, the humidification assembly includes a rotating frame and a moisture absorption plate 1. The bottom of the rotating frame is suitable for being arranged in a water tank 4, the rotating frame has an inner ring surface and an outer ring surface surrounding the outer side of the inner ring surface, a plurality of water storage chambers distributed along the circumferential direction are arranged between the inner ring surface and the outer ring surface, each water storage chamber has a water inlet and a water outlet, the water inlet is arranged on the outer ring surface, and the water outlet is arranged on the inner ring surface; the inner side of the inner ring surface constitutes an installation space, and the moisture absorption plate 1 is arranged in the installation space.

[0034] In this embodiment, if Figure 2As shown, when the humidifying component is working, the rotating frame is set in the water tank 4 so that the lower end of the rotating frame contacts the water in the water tank 4. During the rotation of the rotating frame in the first preset direction, the water in the water tank 4 enters the water storage chamber through the water inlet, and then with the rotation of the rotating frame, the water is stored on one side of the water storage chamber. During the rotation to the top, the water in the water storage chamber gradually falls into the moisture absorption plate 1 through the water outlet, soaking the moisture absorption plate 1. During the rotation of the rotating frame, the water enters different water storage chambers in turn and gradually falls into the moisture absorption plate 1 through the water outlet, and finally the entire moisture absorption plate 1 is soaked; during the rotation of the rotating frame in the second preset direction, the water in the water tank 4 enters the water storage chamber through the water inlet, and then with the rotation of the rotating frame, the water is stored on the other side of the water storage chamber. During the rotation to the top, the water in the water storage chamber gradually falls into the moisture absorption plate 1 through the water outlet, soaking the moisture absorption plate 1. During the rotation of the rotating frame, the water enters different water storage chambers in turn and gradually falls into the moisture absorption plate 1 through the water outlet, and finally the entire moisture absorption plate 1 is soaked. Therefore, the rotating frame can wet the moisture absorption plate 1 when rotating in the first preset direction and the second preset direction, and can rotate in both directions to scoop water and wet the moisture absorption plate 1, so that the humidification component has low requirements for the drive and control of the motor, and can use a lower-cost motor, such as a synchronous motor to drive its rotation, thereby reducing costs. One of the first preset direction and the second preset direction is a clockwise direction, and the other is a counterclockwise direction.

[0035] On the basis of the above-mentioned embodiments, in a preferred embodiment, the water inlet is arranged at the center of the outer wall of the water storage chamber, the water outlet is opposite to the water inlet, and the water outlet is arranged at the center of the inner wall of the water storage chamber, and the water outlet and the water inlet of each water storage chamber are arranged relative to each other. It should be noted that the outer wall of the water storage chamber refers to the side wall away from the rotation center of the rotating frame, and the inner wall of the water storage chamber refers to the side wall close to the rotation center of the rotating frame. The outer wall is part of the outer annular surface, and the inner wall is part of the inner annular surface. In this embodiment, by arranging the water inlet at the center of the outer wall of the water storage chamber and the water outlet at the center of the inner wall of the water storage chamber, the amount of water stored in the water storage chamber can be the same when the rotating frame rotates in the first preset direction and in the second preset direction, and the same humidification effect can be achieved when rotating in the first preset direction and in the second preset direction.

[0036] like Figure 1 and Figure 2As shown, on the basis of the above-mentioned embodiment, in a preferred embodiment, the rotating frame includes a first bracket 2 and a second bracket 3. The first bracket 2 includes a first central connection portion 201 and a first annular structure 202 surrounding the outside of the first central connection portion 201, and the first annular structure 202 is connected to the first central connection portion 201 through a plurality of first spokes 203; the second bracket 3 is docked with the first bracket 2, and the second bracket 3 includes a second central connection portion 301 and a second annular structure 302 surrounding the outside of the second central connection portion 301, and the second annular structure 302 is connected to the second central connection portion 301 through a plurality of second spokes 303. After the first bracket 2 and the second bracket 3 are docked, an installation space is constructed between the first bracket 2 and the second bracket 3, and the moisture absorption disc 1 is arranged in the installation space, that is, the moisture absorption disc 1 is located between the first spoke 203 and the second spoke 303. In this embodiment, the moisture absorbing disc 1 is clamped between the first spoke 203 and the second spoke 303, and the first bracket 2 and the second bracket 3 can cooperate to limit the position of the moisture absorbing disc 1 to ensure that the moisture absorbing disc 1 will not fall off the rotating frame. At the same time, when the humidifying component is applied to the air purifier, the first spoke 203 and the second spoke 303 will not affect the flow of air, and the humidifying component has a small number of parts, and the mold structure for processing the humidifying component is simple and low in cost. In an alternative embodiment, the rotating frame is an integrated structure, including an annular structure with a hollow cavity, a plurality of partition plates are provided in the annular structure, and the annular structure is divided into a plurality of water storage chambers. The inner side of the inner ring surface of the annular structure constitutes an installation space, and the moisture absorbing disc 1 is installed in the installation space. The moisture absorbing disc 1 can be connected to the inner ring surface of the annular structure by gluing.

[0037] On the basis of the above embodiments, in a preferred embodiment, the first annular structure 202 includes a plurality of first cavities 2021, the second annular structure 302 includes a plurality of second cavities 3021, and after the second bracket 3 is docked with the first bracket 2, the first cavity 2021 and the second cavity 3021 together constitute a water storage cavity. Figure 3 and Figure 4 As shown, the first annular structure 202 includes a first annular plane 2026 , on which a plurality of first I-shaped structures 2027 are arranged at intervals, and the area between two adjacent first I-shaped structures 2027 constitutes a first cavity 2021 .

[0038] like Figure 5 and Figure 6As shown, the second annular structure 302 includes a second annular plane 3026, and a plurality of second I-shaped structures 3027 are arranged at intervals on the second annular plane 3026, and the area between two adjacent second I-shaped structures 3027 constitutes a second cavity 3021. During installation, the first I-shaped structure 2027 and the second I-shaped structure 3027 are opposite to each other, and the first cavity 2021 and the second cavity 3021 jointly form a water storage cavity. Specifically, during operation, when the rotating frame rotates according to the first preset direction, the "]" side of the first I-shaped structure 2027 and the second I-shaped structure are responsible for scooping water, and when rotating according to the second preset direction, the "[" side is responsible for scooping water. In this embodiment, since the water storage cavity is formed by the first cavity 2021 and the second cavity 3021, it can be ensured that during the rotation of the rotating frame, water is evenly located in the first cavity 2021 and the second cavity 3021, which can ensure the balanced rotation of the rotating frame. In an alternative embodiment, only the first annular structure 202 includes a plurality of first cavities 2021, and the first cavities 2021 constitute a water storage cavity. In another alternative embodiment, only the second annular structure 302 includes a plurality of second cavities 3021, and the second cavities 3021 constitute a water storage cavity.

[0039] Based on the above embodiment, in a preferred embodiment, the outer annular surface includes a first outer peripheral wall 2022 of the first annular structure 202 and a second outer peripheral wall 3022 of the second annular structure 302, and the water inlet includes a first water inlet hole 2023 provided on the first outer peripheral wall 2022 and a second water inlet hole 3023 provided on the second outer peripheral wall 3022. Figure 3 and Figure 4 The outer planes of the plurality of first I-shaped structures 2027 constitute the first outer peripheral wall 2022 of the first annular structure 202, and the gap between the outer planes of two adjacent first I-shaped structures 2027 constitutes the first water inlet hole 2023; further combined Figure 5 and Figure 6 , the outer planes of the plurality of second I-shaped structures 3027 constitute the second outer peripheral wall 3022 of the second annular structure 302, and the gap between the outer planes of two adjacent second I-shaped structures 3027 constitutes the second water inlet hole 3023. In this embodiment, since the first outer peripheral wall 2022 has the first water inlet hole 2023 and the second outer peripheral wall 3022 has the second water inlet hole 3023, the area of ​​the water inlet can be ensured, thereby ensuring the amount of water entering the water storage cavity and ensuring the wetting effect on the moisture absorption plate 1. In an alternative embodiment, the water inlet only includes the first water inlet hole 2023 provided on the first outer peripheral wall 2022. In another alternative embodiment, the water inlet only includes the second water inlet hole 3023 provided on the second outer peripheral wall 3022.

[0040] like Figure 6As shown, in one embodiment, the diameters of the first peripheral wall 2022 and the second peripheral wall 3022 are the same, which facilitates the docking of the first cavity 2021 and the second cavity 3021. In other alternative embodiments, the diameters of the first peripheral wall 2022 and the second peripheral wall 3022 are different, for example, the diameter of the first peripheral wall 2022 is larger than the diameter of the second peripheral wall 3022, or the diameter of the second peripheral wall 3022 is larger than the diameter of the first peripheral wall 2022.

[0041] On the basis of the above embodiment, in a preferred embodiment, the inner annular surface includes a first inner circumferential wall 2024 of the first annular structure 202 and a second inner circumferential wall 3024 of the second annular structure 302, the first inner circumferential wall 2024 and the second inner circumferential wall 3024 have the same diameter, a first water outlet hole 2025 is provided on the first inner circumferential wall 2024, a second water outlet hole 3025 is provided on the second inner circumferential wall 3024, and the first water outlet hole 2025 and the second water outlet hole 3025 are connected to form a water outlet. Figure 3 and Figure 4 The inner planes of the plurality of first I-shaped structures 2027 constitute the first inner peripheral wall 2024 of the first annular structure 202, and the gap between the inner planes of two adjacent first I-shaped structures 2027 constitutes the first water outlet 2025; further combined Figure 5 and Figure 6 The inner planes of the plurality of second I-shaped structures 3027 constitute the second inner peripheral wall 3024 of the second annular structure 302, and the gap between the inner planes of two adjacent second I-shaped structures 3027 constitutes the second water inlet hole 3023. In this embodiment, since the first water outlet hole 2025 and the second water outlet hole 3025 are connected to form a water outlet, the area of ​​the water outlet is large, so the water output for humidifying the moisture absorption disk 1 is large, and the humidification effect can be ensured. In an alternative embodiment, the water outlet only includes the first water outlet hole 2025. In another alternative embodiment, the water outlet only includes the second water outlet hole 3025.

[0042] On the basis of the above-mentioned embodiment, in a preferred embodiment, gear teeth 304 distributed along the circumferential direction are provided on the second annular structure 302. In this embodiment, by providing the gear teeth 304 distributed along the circumferential direction on the second annular structure 302, the gear teeth 304 can be meshed and connected with a gear, and when the gear rotates under the drive of the motor, the rotating frame is driven to rotate, and there is no need to set a rotating shaft at the center of the rotating frame, so that the moisture absorption disc 1 does not need to be inserted on the rotating shaft, which facilitates the installation of the moisture absorption disc 1. In an alternative embodiment, one side of the rotating frame can be connected to the rotating shaft, and the rotating frame can be driven to rotate by connecting the rotating shaft through the motor.

In this embodiment, the bottom of the rotating frame contacts the water in the water tank 4, and during the rotating frame rotating in the first preset direction, the water in the water tank 4 enters the water storage chamber through the water inlet, and then as the rotating frame rotates, the water is stored on one side of the water storage chamber, and during the rotating process to the top, the water in the water storage chamber gradually falls into the moisture absorption disc 1 through the water outlet, soaking the moisture absorption disc 1, and during the rotating process of the rotating frame, the water enters different water storage chambers in turn and gradually falls into the moisture absorption disc 1 through the water outlet; during the rotating process of the rotating frame rotating in the second preset direction, the water in the water tank 4 enters the water storage chamber through the water inlet, and then as the rotating frame rotates, the water is stored on the other side of the water storage chamber, and during the rotating process to the top, the water in the water storage chamber gradually falls into the moisture absorption disc 1 through the water outlet, soaking the moisture absorption disc 1, and during the rotating process of the rotating frame, the water enters different water storage chambers in turn and gradually falls into the moisture absorption disc 1 through the water outlet.

Since the rotating frame of the humidifying component can wet the hygroscopic disc 1 when rotating in the first preset direction and the second preset direction, and can rotate bidirectionally to scoop water and wet the hygroscopic disc 1, the humidifying component has low requirements for the drive and control of the motor, and can use a lower-cost motor, such as a synchronous motor to drive its rotation, thereby reducing the cost of the entire device.
