[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application.

[0048] First of all, those skilled in the art should understand that these embodiments are only used to explain the technical principles of this application and are not intended to limit the protection scope of this application. Those skilled in the art can adjust them as needed to adapt to specific application scenarios.

[0049] Secondly, it should be noted that in the description of this application, terms such as "inner" and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0050] In addition, it should also be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this disclosure. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0052] A humidifier can adjust the humidity of indoor air to meet the user's demand for indoor air comfort. A humidifier generally includes a water tank for storing the water required for humidification. An openable upper cover is provided above the water tank to facilitate the water filling operation. Currently, in order to improve the convenience of water filling, a water filling port can be opened on the upper cover, and the water filling port is directly communicated with the inside of the water tank, and water can be directly added into the water tank through the water filling port.

[0053] However, when the current humidifier is refilled with water, the water directly falls into the water tank through the water filling port on the upper cover. Since there is a large height difference between the upper cover of the water tank and the water level inside the water tank, during the water filling process, the water directly flows down from a high place to the water surface inside the water tank, generating a relatively large water filling noise and resulting in a poor user experience.

[0054] To solve the above problems, the embodiments of the present application provide a water tank assembly and a humidifying device. By arranging a water guiding structure inside the water tank, when a user fills water from above the upper cover, the water entering the water tank can be guided by the water guiding structure instead of directly falling onto the water surface inside the water tank, thereby reducing or eliminating the noise during water filling, achieving a silent effect when the humidifying device fills water without opening the cover, and improving the user experience.

[0055] For ease of understanding, first, the application scenarios of the water tank assembly and the humidifying device provided by the embodiments of the present application will be described.

[0056] The water tank assembly provided by the embodiments of the present application can be applied to a humidifying device. The humidifying device can be applied in indoor occasions where air humidity needs to be adjusted. The humidifying device can be powered by an external power supply or can be self-powered. The embodiments of the present application do not make specific limitations in this regard. The humidifying device in the embodiments of the present application can be a humidifier or a humidifying module applied in other devices such as air conditioners and air handling equipment. In addition, the liquid added inside the humidifying device in the embodiments of the present application for generating water vapor or mist can be pure water or an aqueous solution mixed with additives such as spices, bactericides, and essential oils. The embodiments of the present application do not make specific limitations in this regard and will be collectively referred to as "water" hereinafter without further specific examples.

[0057] Figure 1 FIG. is an exploded view of the water tank assembly provided by the embodiments of the present application. Figure 2 FIG. is an exploded view of the upper cover and the water guiding member of the water tank assembly provided by the embodiments of the present application. Figure 3 FIG. is a cross-sectional view of the water tank assembly provided by the embodiments of the present application.

[0058] As Figures 1 to 3 shown, the embodiments of the present application provide a water tank assembly 10, and the water tank assembly 10 can be used in a humidifying device. The water tank assembly 10 includes a box body 100, an upper cover 200, and a water guiding member 300. The box body 100 is used to store the water required for humidifying the humidifying device. An opening 101 is provided at the top of the box body 100, and the upper cover 200 is disposed on the opening 101 and connected to the box body 100. The water guiding member 300 is connected to the side of the upper cover 200 facing the inside of the box body 100.

[0059] Wherein, a water guiding cavity 301 is formed by surrounding between the upper cover 200 and the water guiding member 300, and the upper cover 200 is provided with a water filling port 201 communicating with the water guiding cavity 301. There is a gap 102 between the edge of the water guiding member 300 and the inner wall of the box body 100, and the water guiding cavity 301 communicates with the gap 102. The water guiding member 300 is configured to drain the water in the water guiding cavity 301 to the gap 102.

[0060] It can be understood that when the water tank assembly 10 is filled with water, the user does not need to open the upper cover 200 and can directly fill water through the water filling port 201 on the upper cover 200. The added water enters the water guiding cavity 301 through the water filling port 201, and the water guiding member 300 can guide the water entering the water guiding cavity 301, that is, the water entering the water guiding cavity 301 can flow along the water guiding member 300. The water guiding member 300 can drain the water in the water guiding cavity 301 to the position of the gap 102 between the water guiding member 300 and the inner wall of the box body 100. The water entering the gap 102 contacts the inner wall of the box body 100 and can flow downward along the inner wall of the box body 100 under the action of gravity until the water surface inside the box body 100.

[0061] It should be noted that in the water tank assembly 10 provided by the embodiment of the present application, the upper cover 200 is located at the top of the box body 100, and there is a large height difference between the upper cover 200 and the bottom of the box body 100. The water guiding member 300 is connected to the lower side of the upper cover 200 inside the box body 100, that is, the water guiding member 300 is located at a position close to the top of the box body 100 inside the box body 100. The height difference between the water guiding member 300 and the upper cover 200 is small, that is, the height of the water guiding cavity 301 is relatively small. The water added from the water filling port 201 falls on the surface of the water guiding member 300 after entering the water guiding cavity 301 and will not generate noise due to impact. The water guiding member 300 can guide the water added from the water filling port 201 of the upper cover 200, so that the added water can flow along the inner wall of the water tank into the water tank after being guided by the water guiding cavity 301, thereby avoiding the generation of water filling noise and achieving the effect of silent water filling.

[0062] Please continue to refer to Figures 1 to 3 , in some embodiments, the edge contour of the water guiding member 300 matches the cross-sectional shape of the inner wall of the box body 100. The gap 102 is arranged in a ring shape around the circumference of the inner wall of the box body 100, and the added water can flow down from different positions in the circumferential direction of the inner wall of the box body 100, improving the water filling efficiency.

[0063] Among them, the box body 100 can be a cylindrical structure. The cross-sectional shape of the inner wall in the radial direction of the box body 100 can be circular, and the edge contour of the water guiding member 300 can be circular. The diameter dimension of the edge contour of the water guiding member 300 is smaller than the cross-sectional diameter of the inner wall of the box body 100, so as to ensure that a gap 102 can be formed between the outer circumference of the water guiding member 300 and the inner wall of the box body 100. In this way, the water falling above the water guiding member 300 flows along the water guiding member 300 and then flows downward along the inner wall of the box body 100 along the gap 102 after reaching the edge of the water guiding member 300.

[0064] Exemplarily, the water guiding member 300 and the box body 100 can be coaxially arranged, that is, the centers of the water guiding member 300 and the box body 100 coincide, so that the annular gap 102 between the water guiding member 300 and the inner wall of the box body 100 maintains an equal width dimension in the extending direction. In this way, when the water flows to different positions in the circumferential direction of the water guiding member 300, the flow velocities in different directions can be kept equal or approximate, avoiding the accumulation of water on one side of the water guiding cavity 301.

[0065] Exemplarily, the width dimension of the gap 102 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 5 mm, 10 mm, etc. The specific dimension of the gap 102 can be set according to the size of the water filling port 201 and the possible water filling flow rate range during actual water filling. The embodiments of the present application do not make specific limitations on this.

[0066] It should be noted that the contour shape of the water guiding member 300 and the cross-sectional shape of the inner wall of the box body 100 can be square, oval, spindle-shaped or other regular shapes. The embodiments of the present application do not make specific limitations on the types of the contour shape of the water guiding member 300 and the cross-sectional shape of the inner wall of the box body 100.

[0067] Figure 4 For Figure 3 the partial view at position A in Figure 5 For Figure 3 the partial view at position B in

[0068] Please refer to Figures 1 to 5 , in a possible implementation manner, a water retaining rib 310 is provided on the circumferential edge of the water guiding member 300, a notch 311 is provided on the water retaining rib 310, and the water guiding cavity 301 is configured to communicate with the gap 102 through the notch 311.

[0069] It can be understood that the water retaining rib 310 protrudes relative to the upper surface of the water guiding member 300. The water retaining rib 310 can play a guiding role in the water flow flowing from the surface of the water guiding member 300 to the edge, so that the water flow converges towards the notch 311, which is beneficial to the collection of the water flow entering the water guiding cavity 301 and improves the flow rate of the water flow entering the gap 102. In addition, in this way, it can be avoided that the water on the surface of the water guiding member 300 directly drips from its edge and cannot contact the inner wall of the box body 100.

[0070] Exemplarily, the water retaining rib 310 may extend along the edge of the water guiding member 300. The thickness and height of the water retaining rib 310 at different positions extending along the edge of the water guiding member 300 may be equal. The embodiments of the present application do not limit the specific thickness and height dimensions of the water retaining rib 310.

[0071] Exemplarily, the depth of the notch 311 may be equal to the height of the water retaining rib 310, or the depth of the notch 311 may be slightly less than the height of the water retaining rib 310. The embodiments of the present application do not limit the specific value of the depth of the notch 311.

[0072] Exemplarily, the water retaining rib 310 and the main body structure of the water guiding member 300 may be integrally formed. The material of the water guiding member 300 may be plastic or metal, and the embodiments of the present application do not specifically limit this.

[0073] It should be noted that the water guiding member 300 and the upper cover 200 may be connected by snap connection, or the water guiding member 300 and the upper cover 200 may be connected by fasteners such as bolts, or the water guiding member 300 and the upper cover 200 may be connected by ultrasonic welding. The embodiments of the present application do not specifically limit this.

[0074] In some embodiments, there may be a plurality of notches 311, and the plurality of notches 311 are arranged at intervals around the circumference of the water guiding member 300.

[0075] It can be understood that the plurality of notches 311 can disperse the water flow during water addition, preventing the water flow in the water guiding cavity 301 from overflowing from the water retaining rib 310.

[0076] Exemplarily, the number of the notches 311 may be one, two, three, four or more. The embodiments of the present application do not limit the specific number of the notches 311. For example, when there are four notches 311, the four notches 311 are arranged at equal angles in the circumferential direction of the water guiding member 300, and the arc angle between adjacent two notches 311 with respect to the center of the water guiding member 300 is 90°.

[0077] In some embodiments, on the side of the upper cover 200 facing away from the inside of the box body 100, there is a water adding groove 202. There are a plurality of water adding ports 201, and the plurality of water adding ports 201 are located at the bottom of the water adding groove 202. The plurality of water adding grooves 202 are arranged at intervals around the center of the water adding groove 202, thereby preventing water from overflowing to the outside of the water tank when adding water.

[0078] It can be understood that the upper surface of the upper cover 200 is a structure concave into the interior of the water tank, thereby forming a water filling groove 202, and the water filling port 201 is located at the middle position of the water filling groove 202. The water filling groove 202 can increase the water filling area when pouring water onto the upper cover 200, avoiding water overflow or splashing during water filling. The water poured into the water filling groove 202 converges towards the middle and flows downward through the water filling port 201 into the water guiding cavity 301 below.

[0079] Exemplarily, the number of the water filling ports 201 can be two, three, four or more, and the shape of the water filling ports 201 can be circular, oval, strip-shaped or other shapes. The embodiments of the present application do not make specific limitations on the specific size, number and shape of the water filling ports 201.

[0080] In the embodiments of the present application, the water tank assembly 10 can be used on a humidifying device, and the humidifying device can atomize and discharge the water in the water tank assembly 10 to achieve the humidifying function. The water tank assembly 10 can be provided with a structure for discharging mist, and the following will describe this in detail.

[0081] Please continue to refer to Figures 1 to 5 , in a possible implementation manner, a mist outlet pipe 110 is provided in the box body 100, and the mist outlet pipe 110 faces the opening 101. The water guiding member 300 has a first through hole 302, and one end of the mist outlet pipe 110 facing the opening 101 penetrates through the first through hole 302. The water guiding member 300 has a water guiding surface 303 circumferentially arranged around the first through hole 302.

[0082] It can be understood that two regions are formed below the upper cover 200. One of them is provided with the first through hole 302 for facilitating the penetration of the mist outlet pipe 110, and the other region forms a water guiding surface 303 surrounding the circumferential side of the first through hole 302. The water filling port 201 is opposite to the water guiding surface 303. In this way, the water guiding cavity 301 and the mist outlet pipe 110 can be isolated. The water added from the water filling port 201 will drip onto the water guiding surface 303 and will not drip into the mist outlet pipe 110.

[0083] In some embodiments, the water guiding surface 303 is inclined relative to the horizontal plane. Among them, the inner edge position of the water guiding surface 303 close to the first through hole 302 is higher than the outer edge position of the water guiding surface 303 close to the inner wall of the box body 100, so that the gravity of the water flow can be utilized to make the water flow towards the gap 102 between the inner wall of the water tank and the water guiding member 300, avoiding water accumulation in the water guiding cavity 301.

[0084] It can be understood that the water guiding surface 303 is an annular surface, the first through hole 302 is located at its inner edge, and the inner wall of the box body 100 is located at its outer edge. The position where the first through hole 302 is located is higher than the position of the outer edge of the water guiding surface 303. When water drops from the water filling port 201 onto the water guiding surface 303, under the action of gravity, the water flow will flow towards the inner wall of the box body 100 and will not enter the first through hole 302.

[0085] Exemplarily, the inclination angle of the water guiding surface 303 relative to the horizontal direction can be 1° - 89°, including but not limited to 1°, 5°, 10°, 20°, 30°, 45°, 60°, 89°, etc. The embodiments of the present application do not make specific limitations on this.

[0086] In a possible implementation manner, the upper cover 200 has a second through hole 203, and the second through hole 203 is opposite to the first through hole 302. The water tank assembly 10 may further include a mist outlet cover 400. The mist outlet cover 400 is connected to the upper cover 200, is opposite to the second through hole 203, and communicates with the mist outlet pipe 110 through the second through hole 203.

[0087] It can be understood that the water mist from the mist outlet pipe 110 can enter the mist outlet cover 400 after flowing out from its top end, and the water mist is discharged through the mist outlet cover 400, so that the water mist of the mist outlet pipe 110 can be guided to the outside of the upper cover 200, improving the smoothness of mist outlet.

[0088] Exemplarily, the first through hole 302 and the second through hole 203 can be coaxially arranged. The lower end of the mist outlet cover 400 can pass through the second through hole 203 and extend below the upper cover 200, and the upper end of the water guiding pipe can pass through the first through hole 302 to be docked with the mist outlet cover 400.

[0089] It should be noted that the first through hole 302 can be arranged at the central position of the water guiding member 300, the second through hole 203 is located at the central position of the upper cover 200, and the mist outlet pipe 110 is located at the central position of the box body 100. The three are coaxially arranged. The water guiding cavity 301 is an annular cavity.

[0090] In some embodiments, one side of the water guiding member 300 facing the upper cover 200 has a first limiting portion 320, and the first limiting portion 320 can be arranged around the first through hole 302. One side of the upper cover 200 facing the water guiding member 300 has a second limiting portion 210, and the second limiting portion 210 is arranged around the second through hole 203. The second limiting portion 210 can be blocked inside or outside the first limiting portion 320.

[0091] It can be understood that the cooperation of the first limiting portion 320 and the second limiting portion 210 can limit the assembly of the water guiding member 300 and the upper cover 200, improve the installation accuracy of the water guiding member 300, and ensure that the size of the gap 102 between the water guiding member 300 and the inner wall of the box body 100 is within a reasonable range.

[0092] In addition, the first limiting portion 320 and the second limiting portion 210 are disposed inside the water guiding cavity 301 , which can block water entering the water guiding cavity 301 from the water inlet 201 and prevent water from entering the first through hole 302 and the mist outlet pipe 110 .

[0093] In some embodiments, the mist outlet cover 400 may include a top cover 410 and a bottom cover 420, the bottom cover 420 is connected to the upper cover 200, and the top cover 410 is connected to the side of the bottom cover 420 away from the upper cover 200. The top cover 410 may be provided with a mist outlet 411, the bottom cover 420 is at least partially inserted into the second through hole 203, and the end of the bottom cover 420 facing the inside of the box 100 may be provided with a mist inlet 421, and the mist inlet 421 is connected to the mist outlet pipe 110, so that the efficiency of mist discharge from the mist outlet cover 400 can be improved.

[0094] It can be understood that the bottom cover 420 can be connected to the upper cover 200 by a snap-fit, and a raised portion arranged around the second through hole 203 can be provided on the upper side of the upper cover 200. The bottom cover 420 is inserted into the inner side of the raised portion. When water is added to the water inlet 201, the raised portion can play a water blocking role to prevent water from entering the second through hole 203.

[0095] Exemplarily, the bottom cover 420 and the top cover 410 may be connected by a snap connection, or may be connected by ultrasonic welding, or may be connected by fasteners such as bolts, etc., which is not specifically limited in the embodiments of the present application.

[0096] In some embodiments, a sealing groove 111 may be provided at the top inner edge of the mist outlet pipe 110. A sealing member 500 is provided in the sealing groove 111. The sealing member 500 is disposed around the circumferential inner edge of the mist outlet pipe 110. The mist outlet cover 400 may abut against the sealing member 500.

[0097] It is understandable that the lower end of the mist outlet cover 400 abuts against the upper end of the sealing member 500 , which can prevent water from seeping into the mist outlet pipe 110 when adding water, and can also prevent water mist from entering the water guide cavity 301 .

[0098] Exemplarily, the seal 500 can be a sealing ring made of elastic material such as rubber or silicone. The thickness of the lower end of the seal 500 is greater than the thickness of the upper end. The middle of the seal 500 is a narrowing structure, so that the abutment between the mist outlet cover 400 and the upper end of the seal 500 can compress the seal 500 to produce elastic deformation, thereby improving the sealing effect.

[0099] It should be noted that in the embodiment of the present application, the upper cover 200 and the box body 100 can be connected in a detachable manner by means of snaps or fasteners, and the upper cover 200 can be opened when the water tank needs to be cleaned.
