[0062] Referring to Figure 1 , the present application provides a humidifier comprising a humidifying assembly 100 for generating water mist. It is to be 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 assembly 100 can also be installed in other electrical appliances with humidifying function, which are not limited herein.

[0063] As described in the background, the existing humidifier is provided with an atomizer for generating water mist and a fan for blowing out water mist. In order to prevent the water flow from flowing back into the fan, the design of lengthening the fan outlet is usually adopted, but this will cause a large amount of water mist at the bottom to be unable to be blown out by the wind force, affecting the efficiency of the humidifier. Moreover, in order to ensure that the mist outlet of the humidifier for flowing out water mist is in the middle, 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, thereby causing less mist to be discharged in the area close to the atomizer, and the water mist cannot be uniformly discharged, thereby affecting the mist discharging effect of the humidifier.

[0064] In order to solve the above technical problems, as shown in Figure 1 , the humidifying assembly 100 of the present application comprises a main housing 20, an air outlet column 40, and a flow guide 60.

[0065] The main housing 20 has a mist outlet channel 100a, and the mist outlet channel 100a has an open end 100b and a closed end 100c oppositely arranged in the Z direction in the first direction (i.e. Figure 1 , the mist in the mist outlet channel 100a flows out from the closed end 100c to the open end 100b. When the humidifying assembly 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 the air outlet column 40 forms an airflow channel 41 extending in the first direction. The air outlet column 40 has an air outlet 43 opened on the side wall of one end thereof facing the open end 100b, and the air outlet 43 communicates the airflow channel 41 with the mist outlet channel 100a. One end of the air outlet column 40 facing the closed end 100c forms an air inlet, and the air inlet communicates the airflow channel 41 with the external atmosphere.

[0067] The flow guide 60 is located in the mist outlet channel 100a and outside the air outlet 43. The orthographic projection of the flow guide 60 on the air outlet column 40 covers the air outlet 43, so that the air flow in the air flow channel 41 spirally flows 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 orthographic projection of the flow guide 60 on the air outlet column 40 covers the air outlet 43, the air outlet 43 is partially blocked, which causes the air flow to spirally flow in the mist outlet channel 100a, so that the air flow is fully mixed with the water mist, the water mist is rapidly dispersed 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 humidifying assembly 100 is uniform.

[0069] Please refer to 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.

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

[0071] The water tank 23 is a shell structure with one end open, which is sleeved outside one end of the water storage tank 21 in the first direction. The water tank 23 includes a water tank bottom wall 232 and a water tank side wall 234, which is formed from the edge of the water tank bottom wall 232 in the first direction and surrounds the water tank bottom wall 232 in the circumferential direction. The water tank cover 25 is a hollow rotary body structure, which is sleeved outside the other end of the water storage tank 21 in the first direction, and the water tank cover 25 is connected to the 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 a ring structure, which is sleeved outside the 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 connected in the first direction and surround the water storage tank 21. The water storage tank 21, the water tank 23, the water tank cover 25, and the mist outlet decorative cover 27 together form a mist outlet channel 100a around the water storage tank 21 in the circumferential direction. The central axis of the mist outlet channel 100a coincides with the central axis of the water storage tank 21. 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 comprises an atomizer 80 mounted on the bottom wall of the water tank 21 near the closed end 100c of the mist outlet passage 100a, the atomizer 80 being configured to atomize water flowing out of the water 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 23 in a first direction towards the open end 100b of the mist outlet passage 100a, the air outlet column 40 having a quadrilateral cross section perpendicular to the first direction, one side wall of the air outlet column 40 being connected to the inner side wall of the water tank 23, the air outlet column 40 having an air inlet opening at one end thereof near the bottom wall 232 of the water tank 23, the air inlet opening being in communication with the air flow passage 41, and the air outlet column 40 having an air outlet opening 43 at the side wall of the other end thereof away from the bottom wall 232 of the water tank 23.

[0075] Please refer to Figure 1 , Figure 3 and Figure 4 , in some embodiments, the air outlet opening 43 comprises a first air outlet opening 432 and a second air outlet opening 434, the first air outlet opening 432 and the second air outlet opening 434 being spaced apart in the circumferential direction of the mist outlet passage 100a, the orthographic projection of the flow guide 60 on the air outlet column 40 covering the first air outlet opening 432 and completely covering the second air outlet opening 434.

[0076] Specifically, the flow guide 60 is convexly provided on the end face of the water tank cover 25 towards the closed end, and comprises a flow guide front wall 61, a first flow guide side wall 63 and a second flow guide side wall 65, the flow guide front wall 61 extending along the inner side edge of the water tank cover 25 in an arc shape, the first flow guide side wall 63 and the second flow guide side wall 65 being located at opposite sides of the flow guide front wall 61 in the circumferential direction of the air flow passage 41. The first flow guide side wall 63 is spaced apart from one side of the first air outlet opening 432 in the circumferential direction of the air flow passage 41, and the orthographic projection of the first flow guide side wall 63 on the air outlet column 40 covers the side of the first air outlet opening 432 near the open end 100b. The second flow guide side wall 65 is spaced apart from one side of the second air outlet opening 434 in the circumferential direction of the air flow passage 41, and the orthographic projection of the second flow guide side wall 65 on the air outlet column 40 completely covers the second air outlet opening 434.

[0077] Specifically, in an embodiment, the first flow guide side wall 63 is inclinedly extended from one end to the other end of the flow guide front wall 61 towards the side edge of the bottom wall 232 of the water tank 23 in a direction away from the bottom wall 232 of the water tank 23, so as to not completely shield the first air outlet opening 432 and effectively guide the spiral flow of the air flow flowing out of the first air outlet opening 432. As a preferred embodiment, the area A1 of the first flow guide side wall 63 and the area A2 of the second flow guide side wall 65 satisfy 0≤S1≤0.5A2.

[0078] Thus, due to the partial blocking of the first air outlet 432 by the flow guide 60, the airflow flowing out of the first air outlet 432 moves laterally in a direction perpendicular to the first direction without blowing away all the water mist generated by the atomizer 80. Due to the full blocking of the second air outlet 434 by the flow guide 60, the airflow flowing out of the second air outlet 434 flows downward in the first direction away from the flow guide 60. Due to the Bernoulli effect, the two airflows affect each other, and the airflow flowing out of the first air outlet 432 is deflected toward the bottom wall 232 of the water tank 23, while the airflow flowing out of the second air outlet 434 is deflected laterally in a direction perpendicular to the first direction. In this way, both airflows flow spirally downward, thereby diffusing the water mist in the water tank 23 and carrying more water mist. Under the influence of the open end 100b of the mist outlet channel 100a, the airflow in the mist outlet channel 100a spirally flows toward the open end 100b, thereby forming a uniform water mist.

[0079] Please refer to Figure 1 , Figure 5 It is shown that, in some embodiments, the distance S1 between the flow guide front wall 61 of the flow guide 60 and the outer wall of the water storage tank 21, the distance S2 between the outer wall of the water storage tank 21 and the inner wall of the water tank cover 25, and the minimum distance S3 between the flow 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 flow guide front wall 61 and the air outlet column 40 is large, 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 flow guide front wall 61 and the outer wall of the water storage tank 21, the cross-sectional area of the mist outlet channel 100a from bottom to top becomes smaller, which can accelerate the outflow speed of the water mist.

[0081] Please refer to Figure 1 , Figure 6 It is shown that, in some embodiments, the distance S41 of the first flow 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 flow 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, there is enough gap between the flow guide 60 and the air outlet column 40 for flow guiding, thereby reducing the flow loss of the airflow.

[0082] Please refer to Figure 1 , Figure 7 and Figure 8As shown, in some embodiments, the distance h between the end wall of the air guiding member 60 close to the closed end 100c and the end wall of the air outlet column 40 close to 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, the air flow from the second air outlet 434 can be ensured to flow downward as much as possible towards the bottom wall 232 of the water tank, and the flow loss caused by the air guiding member 60 being too long in the first direction can be reduced.

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

[0084] Please refer to Figure 1 and Figure 9 As shown, in another embodiment, the air outlet column 40 is arranged away from the atomizer 80, and the angle a formed between the line L1 connecting the center axis of the air flow channel 41 and the center axis of the mist outlet channel 100a and the line L2 connecting the center axis of the atomizer 80 and the center axis of the mist outlet channel 100a satisfies: 160°≤a≤180°, so as to prolong the distance of the air flow to the water mist, thereby weakening the flow rate of the air flow, preventing the air flow from being too high to carry away the water mist, and causing the mist to be scarce near the atomizer 80.

[0085] Please refer to Figure 1 and Figure 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 smaller, so as to ensure that the air flow can carry away enough water mist.

[0086] Further, the height difference △h of 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, so as to reduce the loss caused by the interaction between the air flow from the first air outlet 432 and the air flow from the second air outlet 434.

[0087] Please refer to Figure 1 and Figure 11In some other embodiments, only one air outlet 43 is formed on the air outlet column 40, and the flow guide 60 is arranged in the water tank 23 and extends towards the closed end 100c from the end close to the air outlet 43 to the end away from the air outlet 43, and the projection of the flow guide 60 on the air outlet column 40 covers the air outlet 43, so that the flow guide 60 can also guide the air flow to flow spirally. Preferably, the projection of the flow guide 60 on the air outlet column 40 covers one side of the air outlet 43 close to the opening end 100b of the mist outlet channel 100a.

[0088] Further, the distance S5 between the flow guide 60 and the air outlet 43 is greater than or equal to 5 mm, and the distance h3 between the flow guide 60 and the end surface of the air outlet column 40 away from the bottom wall 232 of the water tank is less than or equal to 8 mm, so as to ensure 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 flow guide 60, and the height h4 of the flow guide 60 in the first direction satisfies: h3+0.67h1≤h4≤h3+h1. Wherein, h3 is the distance between the end of the flow guide 60 close to the opening end 100b and the end of the air outlet column 40 close to the opening end 100b, and h1 is the height of the air outlet 43 in the first direction. In this way, the air flow flowing out of the air outlet 43 can flow spirally downward along the water tank 23.

[0089] Further, the length b of the flow guide 60 in the radial direction of the air outlet column 40 satisfies: 20mm≤b≤25mm, so as to ensure that the flow guide 60 has good guiding 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 that the height of the air outlet column 40 is low, so as to ensure that the air flow can carry away sufficient water mist.

[0090] The humidifying assembly 100 and the humidifier provided with the same can make the air flow flowing out of the air flow channel 41 flow spirally along the mist outlet channel 100a, so as to make the air flow and the water mist fully mixed, and make the water mist rapidly spread in the air flow channel 41, finally improve the humidity of the air flow, so that the humidifier can output mist uniformly and have good humidifying effect.

[0091] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the present disclosure.
