[0062] See also Figure 1 The present application provides a humidifier, including a humidifying component 100 for generating water mist. It is understood that the following embodiments are only used as examples and do not limit the technical scope of the present application. In other embodiments, the humidifying component 100 can also be installed in other electrical appliances with humidification functions, which is not limited here.

[0063] As described in the background technology, the existing humidifier is provided with an atomizer for generating water mist and a fan for blowing out the water mist. In order to prevent water from flowing back into the fan, a design of lengthening the fan outlet is usually adopted, but this will cause a large amount of water mist at the bottom layer to be unable to be blown out with the wind, affecting the efficiency of the humidifier. Moreover, in order to ensure that the mist outlet of the humidifier for discharging water mist is centered, the atomizer adopts an eccentric design structure, and the air outlet is close to the atomizer. The airflow blows away the water mist around the atomizer, resulting in less mist in the area close to the atomizer, and the water mist cannot flow out evenly, which affects the misting effect of the humidifier.

[0064] In order to solve the above technical problems, Figure 1 As shown, the humidification assembly 100 of the present application includes a main shell 20 , an air outlet column 40 and a flow guide 60 .

[0065] The main housing 20 has a mist outlet passage 100a, and the mist outlet passage 100a has a first direction (i.e. Figure 1 The open end 100b and the closed end 100c are arranged opposite to each other in the Z direction in the center, and the mist in the mist outlet channel 100a flows out from the closed end 100c to the open end 100b. When the humidifying component 100 is in a normal working state, the open end 100b is located above the closed end 100c.

[0066] The air outlet column 40 is located in the mist outlet channel 100a, and an air flow channel 41 extending along the first direction is formed in the air outlet column 40. An air outlet 43 is formed on the side wall of one end of the air outlet column 40 facing the open end 100b, and the air outlet 43 connects the air flow channel 41 with the mist outlet channel 100a. An air inlet is formed at one end of the air outlet column 40 facing the closed end 100c, and the air inlet connects the air flow channel 41 with the external atmosphere.

[0067] The guide member 60 is located in the mist outlet channel 100a and is arranged outside the air outlet 43. The orthographic projection of the guide member 60 on the air outlet column 40 partially covers the air outlet 43, so that the airflow flowing out of the airflow channel 41 flows in a spiral in the mist outlet channel 100a.

[0068] In this way, the air flow in the air flow channel 41 flows out through the air outlet 43. Since the direct projection of the guide member 60 on the air outlet column 40 partially covers the air outlet 43 and forms a certain shielding on the air outlet 43, the air flow is caused to flow in a spiral in the mist outlet channel 100a, so that the air flow and the water mist are fully mixed, and the water mist is rapidly diffused in the mist outlet channel 100a, and finally the moisture content of the air flow is increased, so that the mist flowing out of the humidification component 100 is sufficiently uniform.

[0069] See also Figure 1 and Figure 2 The main housing 20 includes a water storage tank 21, a water tank 23, a water tank cover 25 and a mist outlet decorative cover 27 which are matched with each other.

[0070] The water tank 21 is a hollow box structure for storing water for atomization, the cross section of the water tank 21 is circular, and the central axis of the water tank 21 extends along the first direction. It can be understood that the shape of the water tank 21 is not limited thereto and can be set as needed to meet different requirements.

[0071] The water tank 23 is a shell-like structure with one end open, and is sleeved outside one end of the water tank 21 in the first direction. The water tank 23 includes a water tank bottom wall 232 and a water tank side wall 234. The water tank side wall 234 is formed by extending from the edge of the water tank bottom wall 232 along the first direction and circumferentially surrounding the water tank bottom wall 232. The water tank cover 25 is a hollow rotating body-like structure, sleeved outside the other end of the water tank 21 in the first direction, and the water tank cover 25 is matched with one end of the water tank side wall 234 of the water tank 23 away from the water tank bottom wall 232. The mist outlet decorative cover 27 is an annular structure, and is sleeved on one end of the water tank cover 25 away from the water tank 23.

[0072] In this way, the water tank 23, the water tank cover 25 and the mist outlet decorative cover 27 are sequentially matched along the first direction and surround the outside of the water tank 21, and the water tank 21 and the water tank 23, the water tank cover 25 and the mist outlet decorative cover 27 together form a mist outlet channel 100a which surrounds the water tank 21 along the circumferential direction. The central axis of the mist outlet channel 100a coincides with the central axis of the water tank 21, and the end of the mist outlet channel 100a close to the water tank bottom wall 232 in the first direction forms a closed end 100c, and the end of the mist outlet channel 100a close to the mist outlet decorative cover 27 in the first direction forms an open end 100b.

[0073] In some embodiments, the humidifying assembly 100 further includes an atomizer 80 , which is mounted on the bottom wall of the water tank and close to the closed end 100 c of the mist outlet channel 100 a . The atomizer 80 is used to atomize water flowing out of the water storage tank 21 to generate water mist.

[0074] The air outlet column 40 is located in the water tank 23, and extends from the bottom wall 232 of the water tank along the first direction toward the open end 100b of the mist outlet channel 100a. The cross-section of the air outlet column 40 perpendicular to the first direction is a quadrilateral. One side wall of the air outlet column 40 is connected to the inner wall of the water tank 23. An air inlet connecting the external atmosphere and the airflow channel 41 is provided at one end of the air outlet column 40 close to the bottom wall 232 of the water tank, and an air outlet 43 is provided on the side wall of the end of the air outlet column 40 away from the bottom wall 232 of the water tank.

[0075] Please combine Figure 1 , Figure 3 as well as Figure 4 As shown, in some embodiments, the air outlet 43 includes a first air outlet 432 and a second air outlet 434, and the first air outlet 432 and the second air outlet 434 are spaced apart in the circumferential direction of the mist outlet channel 100a, and the orthographic projection of the guide member 60 on the air outlet column 40 partially covers the first air outlet 432 and completely covers the second air outlet 434.

[0076] Specifically, the guide member 60 is convexly disposed on an end surface of the water tank cover 25 facing the closed end, and includes a guide front wall 61, a first guide side wall 63, and a second guide side wall 65. The guide front wall 61 extends in an arc shape along the inner edge of the water tank cover 25. In the circumferential direction of the airflow channel 41, the first guide side wall 63 and the second guide side wall 65 are located on opposite sides of the guide front wall 61. The first guide side wall 63 is spaced apart on one side of the first air outlet 432 in the circumferential direction of the airflow channel 41, and the orthographic projection of the first guide side wall 63 on the air outlet column 40 partially covers the side of the first air outlet 432 close to the open end 100b. The second guide side wall 65 is spaced apart on one side of the second air outlet 434 in the circumferential direction of the airflow channel 41, and the orthographic projection of the second guide side wall 65 on the air outlet column 40 completely covers the second air outlet 434.

[0077] Specifically in one embodiment, the first flow guiding side wall 63 extends obliquely from one end connected to the flow guiding front wall 61 to the other end toward the direction away from the water tank bottom wall 232, so that the first air outlet 432 cannot be completely shielded, and the airflow flowing out of the first air outlet 432 can be effectively guided to spirally flow. As a preferred embodiment, the area A1 of the first flow guiding side wall 63 and the area A2 of the second flow guiding side wall 65 satisfy 0≤S1≤0.5A2.

[0078] In this way, since the first air outlet 432 is partially blocked by the guide member 60, the airflow flowing out of the first air outlet 432 moves laterally in a direction perpendicular to the first direction, and the water mist generated by the atomizer 80 will not be blown away completely. Since the second air outlet 434 is completely blocked by the guide member 60, the airflow flowing out of the second air outlet 434 flows downward along the first direction away from the guide member 60. Due to the Bernoulli effect, the two airflows affect each other, and the airflow flowing out of the first air outlet 432 is offset in the direction of the water tank bottom wall 232, and the airflow flowing out of the second air outlet 434 is laterally offset in the direction perpendicular to the first direction. In this way, both airflows flow downward in a spiral, thereby diffusing the mist in the water tank 23 and carrying more mist. Under the influence of the open end 100b of the mist outlet channel 100a, the airflow in the mist outlet channel 100a flows spirally toward the open end 100b, thereby forming a uniform water mist.

[0079] Please combine Figure 1 , Figure 5 As shown, in some embodiments, the distance S1 between the guide front wall 61 of the guide member 60 and the outer wall of the water tank 21, the distance S2 between the outer wall of the water tank 21 and the inner wall of the water tank cover 25, and the minimum distance S3 between the guide front wall 61 and the air outlet column 40 satisfy: S2≤S1<S3, preferably, S2<S1.

[0080] In this way, the minimum distance S3 between the guide front wall 61 and the air outlet column 40 is larger, so that the airflow flowing out of the airflow channel 41 flows smoothly. When the distance S2 between the outer wall of the water storage tank 21 and the inner wall of the water tank cover 25 is smaller than the distance S1 between the guide front wall 61 and the outer wall of the water storage tank 21, the interception area of ​​the mist outlet channel 100a from bottom to top becomes smaller, which can speed up the outflow speed of the water mist.

[0081] Please combine Figure 1 , Figure 6 As shown, in some embodiments, the distance S41 of the first guide side wall 63 relative to the center point of the outlet end of the first air outlet 432 satisfies: 6mm≤S41≤0.5L, and the distance S42 of the second guide side wall 65 relative to the second air outlet 434 also satisfies: 6mm≤S42≤0.5L, where L is the length of the airflow channel 41 in the first direction. In this way, it can be ensured that there is enough gap between the guide member 60 and the air outlet column 40 for guiding, thereby reducing the flow loss of the airflow.

[0082] Please combine Figure 1 , Figure 7 as well as Figure 8As shown, in some embodiments, the distance h between the end wall of the air guide 60 near the closed end 100c and the end wall of the air outlet column 40 near the open end 100b satisfies: 6mm+h1≤h≤0.5H; wherein h1 is the height of the second air outlet 434 in the first direction, and H is the height of the air outlet column 40 in the first direction. In this way, it is ensured that the airflow flowing out of the second air outlet 434 flows downward toward the bottom wall 232 of the water tank as much as possible, and the flow loss caused by the excessive length of the air guide 60 in the first direction is reduced.

[0083] Please review Figure 1 and Figure 6 In some embodiments, the air outlet column 40 is arranged close to the atomizer 80, and the angle α formed by the line L1 connecting the central axis of the airflow channel 41 and the central axis of the mist outlet channel 100a and the line L2 connecting the central axis of the atomizer 80 and the central axis of the mist outlet channel 100a is less than 90°, so as to ensure that the airflow flowing out of the airflow channel 41 can quickly combine with the water mist formed by the atomizer 80.

[0084] Please combine Figure 1 and Fig. 9 As shown, in another embodiment, the air outlet column 40 is arranged away from the atomizer 80, and the angle α formed by the line L1 connecting the central axis of the airflow channel 41 and the central axis of the mist outlet channel 100a and the line L2 connecting the central axis of the atomizer 80 and the central axis of the mist outlet channel 100a satisfies: 160°≤α≤180°, thereby extending the distance from the airflow to the water mist, thereby weakening the airflow velocity, preventing the airflow velocity from being too high and carrying away the water mist, resulting in sparse mist output near the atomizer 80.

[0085] Please combine Figure 1 and Fig.10 As shown, when the air outlet column 40 is arranged away from the atomizer 80, the height H of the air outlet column 40 in the first direction satisfies: 0.42H1≤H≤0.5H1; wherein H1 is the depth of the water tank 23 in the first direction. In this way, the height H of the air outlet column 40 in the first direction is small, so as to ensure that the airflow takes away enough water mist.

[0086] Furthermore, the height difference △h between the first air outlet 432 and the second air outlet 434 in the first direction satisfies: 5mm≤△h≤8mm, and the height of the first air outlet 432 in the first direction is greater than the height of the second air outlet 434 in the first direction, thereby reducing the loss caused by the interaction between the airflow flowing out of the first air outlet 432 and the airflow flowing out of the second air outlet 434.

[0087] Please combine Figure 1 and Fig.11As shown, in other embodiments, only one air outlet 43 is provided on the air outlet column 40, and the guide member 60 is provided in the water tank 23, and from one end close to the air outlet 43 to one end away from the air outlet 43, the guide member 60 bends and extends toward the closed end 100c, and the orthographic projection of the guide member 60 on the air outlet column 40 partially covers the air outlet 43, and the guide member 60 can also play a role in guiding the spiral flow of the airflow. Preferably, the orthographic projection of the guide member 60 on the air outlet column 40 partially covers the side of the air outlet 43 close to the open end 100b of the mist outlet channel 100a.

[0088] Furthermore, the distance S5 between the guide member 60 and the air outlet 43 is ≥5mm, and the distance h3 between the guide member 60 and the end face of the air outlet column 40 away from the bottom wall 232 of the water tank is ≤8mm, thereby ensuring a good guiding effect. In the circumferential direction of the air flow channel 41, the width of the air outlet 43 is equal to the width of the guide member 60, and the height h4 of the guide member 60 in the first direction satisfies: h3+0.67h1≤h4≤h3+h1. Among them, h3 is the distance between one end of the guide member 60 close to the opening end 100b and one end of the air outlet column 40 close to the opening end 100b; h1 is the height of the air outlet 43 in the first direction. In this way, it can be ensured that the airflow flowing out of the air outlet 43 flows downward along the water tank 23 in a spiral.

[0089] Furthermore, the length b of the guide member 60 in the radial direction of the air outlet column 40 satisfies: 20mm≤b≤25mm, thereby ensuring that the guide member 60 has a good guide effect. The height H of the air outlet column 40 in the first direction satisfies: 0.42H1≤H≤0.5H1; wherein H1 is the depth of the water tank 23 in the first direction, so the height of the air outlet column 40 is relatively low to ensure that the airflow can carry away enough water mist.

[0090] The above-mentioned humidification component 100 and the humidifier equipped with it, through the setting of the guide member 60, allow the airflow flowing out of the airflow channel 41 to flow in a spiral along the mist outlet channel 100a, so that the airflow and the water mist are fully mixed, and the water mist is quickly diffused in the airflow channel 41, and finally the moisture content of the airflow is increased, so that the mist outlet of the humidifier is sufficiently uniform, thereby achieving a good humidification effect.

[0091] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0092] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
