[0059] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0060] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0061] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0062] After analyzing the related art ultrasonic humidifier 100, the inventors found that the noise generated by it mainly comes from three sources: the aerodynamic noise emitted by the fan 23 and its airflow channel; the dripping sound caused by water droplets falling on the water surface; and the collision sound of water droplets hitting the inner wall of the ultrasonic humidifier 100. The latter two sounds are collectively referred to as water noise. Since the first sound has been relatively well addressed, this application focuses on addressing the latter two sounds, namely water noise.

[0063] The principle of the ultrasonic humidifier 100 is shown in Figure 1. The high-frequency oscillation plate 11 transfers energy to the water, stirring up a water column 12 in the center of the oscillation plate, rushing out of the liquid surface. After rising to a certain height, the bubbles inside the water column 12 burst, exploding the water clusters. A small part of the water clusters are relatively small particles, forming water mist floating above the water surface. At this time, as long as gas is introduced from the outside, the water mist can be blown out from the mist outlet channel 13.

[0064] After the central water cluster explodes, a small portion of it becomes small particles, forming mist, while the majority of the water cluster forms water droplets that fly out in all directions and upward, as shown in Figure 2. The water droplets that fly out in all directions vary in size. If the atomization chamber is large enough, these water droplets will return to the water surface, which is one of the sources of the water droplet sound (the first water sound). The water droplets that rise straight up from the center lose their kinetic energy after rising to a certain height and fall vertically back to the water surface. This part will collide with the water column 12 rushing up from the bottom. In fact, the water column 12 above the ultrasonic generator is intermittent. Sometimes the rising water column 12 has not yet broken through the water surface, and the water droplets descending from the center have already dripped onto the water surface. This is the second reason for the water droplet sound (the second water sound).

[0065] Due to external factors such as space requirements and cost considerations, the size of the atomizing chamber is limited. (See Figure 3.) At this point, both the surrounding spraying water masses and the central water mass can directly impact the inner wall of the atomizing chamber. This is also one of the sources of water noise (the third type of water noise).

[0066] As shown in Figure 4, the atomizing chamber is filled with mist, which gradually forms droplets on the inner wall. When the droplets on the side walls gather to a certain size, they slide down the side walls under the action of gravity and fall into the water slowly and silently. The droplets on the top surface gradually gather and grow until they drip from the top surface, which is also one of the sources of the dripping sound (the fourth type of water sound).

[0067] Based on the above research, the inventors propose an atomizing device 200 to improve the noise pollution when the atomizing device 200 is working.

[0068] The following describes the atomization device 200 according to an embodiment of the present application with reference to Figures 5 to 21.

[0069] 5, 6 and 7, the atomizing device 200 according to the embodiment of the present application includes: a housing 21 and an atomizing element 22, the housing 21 defines an atomizing chamber 210, and the atomizing element 22 is arranged at the bottom of the atomizing chamber 210. When the atomizing device 200 is working, liquid is added to the atomizing chamber 210 so that the liquid covers the atomizing element 22. The atomizing element 22 is suitable for transferring energy to the liquid in the atomizing chamber 210, and a water column that rushes out of the liquid surface is aroused in the center of the atomizing element 22. The tail section of the water column begins to diverge to form water droplets and water mist. A mist outlet 2121 is provided at the top of the atomizing chamber 210, and the mist in the atomizing chamber 210 can be discharged into the room through the mist outlet 2121 to improve the indoor environment.

[0070] To reduce noise pollution generated by the operation of the atomizing device 200, in this embodiment of the present application, the atomizing chamber 210 is provided with a first sidewall 214. The first sidewall 214 is configured as a sound-absorbing structure that contacts the liquid to eliminate the sound of the water. The atomizing element 22 is arranged at an angle relative to the horizontal plane and is used to generate water mist toward the first sidewall 214.

[0071] According to the atomizing device 200 of the embodiment of the present application, by tilting the atomizing element 22 relative to the horizontal plane, the water column stirred up by the atomizing element 22 is ejected at an angle, and the water mass has no obvious explosion, thereby avoiding the noise (the second water sound) generated by the water droplets dropping from the center falling on the water surface in the related art. And the water column is shot toward the first side wall 214, and the water droplets after the water column explodes can be sprinkled toward the first side wall 214 to be silenced by the silencer structure of the first side wall 214, thereby avoiding the noise (the first water sound) generated by the water droplets flying around and dripping on the water surface in the related art. At the same time, the noise (the third water sound) generated by the water droplets sprinkling on the inner wall of the atomizing chamber 210 in the related art is also improved by the silencer structure. The atomizing device 200 proposed in the present application effectively reduces the noise generated when the atomizing device 200 is working through the above technical solution.

[0072] In some specific embodiments, the atomizing end of the atomizing element 22 is tilted relative to the horizontal plane toward the first side wall 214. When the atomizing element 22 is in operation, a water column perpendicular to the atomizing end is formed at the atomizing end. The atomizing end is tilted relative to the horizontal plane toward the first side wall 214 so that the water column can be projected toward the first side wall 214, ensuring that the water droplets can be sprinkled on the first side wall 214 to reduce noise.

[0073] Referring to Figures 6, 7, and 10, in some embodiments, the sound-absorbing structure includes a sound-absorbing material member 215 provided with a sound-absorbing gap on the inner wall of the atomizing chamber 210. This allows water droplets directed toward the first sidewall 214 to land on the sound-absorbing material member 215. The sound-absorbing gap provides sound-absorbing material 215, effectively reducing the sound of the water. This technical solution is simple and easy to source. For example, the sound-absorbing material member 215 can be a sponge, effectively reducing the cost of the atomizing device 200.

[0074] In some embodiments, the sound-absorbing material piece 215 is bonded to the first side wall 214 ; in other embodiments, the sound-absorbing material piece 215 may be snap-fitted or fixed to the first side wall 214 by screws to facilitate replacement of the sound-absorbing material piece 215 .

[0075] Referring to Figure 11, in some other embodiments, the silencer structure can also be a curved surface 2144. After the water column hits the curved surface 2144 at a small angle a, the downstream water flow adheres to the wall of the curved surface 2144 and flows simultaneously along the tangential and downward directions of the curved surface 2144, effectively reducing the noise when the water droplets contact the inner wall of the atomization chamber 210. At the same time, the silencer structure of the curved surface 2144 is also easy to clean, reducing the cleaning cost of the atomization device 200.

[0076] In some specific embodiments, the curved surface 2144 is formed as an arc-shaped surface that bends away from the center of the atomizing chamber 210 . The arc-shaped surface has a simple structure and is easy to process, thereby reducing the cost of the atomizing device 200 .

[0077] In other embodiments, the silencer structure may also be a slope. After the water column hits the slope at a small angle a, the downward water flow adheres to the wall of the slope and flows simultaneously in the horizontal and downward directions of the slope, effectively reducing the noise when the water droplets contact the inner wall of the atomizing chamber 210. At the same time, the silencer structure of the slope is also easy to clean, reducing the cleaning cost of the atomizing device 200.

[0078] 7 , 8 and 9 , in some embodiments, the first side wall 214 includes: a first portion 2141 and a second portion 2142. In the height direction, the first portion 2141 is located above the second portion 2142. The first portion 2141 extends obliquely downward and in a direction away from the center line of the mist outlet 2121. At least a portion of the second portion 2142 is configured as a sound-absorbing structure.

[0079] Because part of the mist in the atomizing chamber 210 will condense into water droplets on the inner wall of the atomizing chamber 210, the above technical solution sets the first part 2141 as an inclined slope so that the water droplets condensed on the first part 2141 can flow toward the silencer structure of the second part 2142, thereby avoiding the direct dripping of the water droplets condensed on the first part 2141, thereby reducing the noise of the atomizing device 200.

[0080] 7 , 8 and 10 , in some further embodiments, the first side wall 214 further includes a third portion 2143 , which is located at the lower end of the second portion 2142 , and the third portion 2143 is formed as an inclined surface extending downward and toward the center line of the mist outlet 2121 .

[0081] The above technical solution, by configuring the third portion 2143 as an inclined surface, allows water on the second portion 2142 to flow down the third portion 2143 into the liquid surface, slowing the rate of water flow and thus reducing the noise of the water. Furthermore, the inclined third portion 2143 also horizontally separates the second portion 2142 from the liquid surface, further reducing the possibility of water droplets directly dripping onto the liquid surface, effectively reducing the noise of the atomization device 200.

[0082] 7 , 8 and 9 , in some embodiments, the mist outlet 2121 is disposed near the first side wall 214 .

[0083] Because in the embodiment of the present application, water droplets explode near the first side wall 214 to produce water mist, by setting the mist outlet 2121 near the first side wall 214, the generated water mist can be quickly discharged through the mist outlet 2121, thereby reducing the risk of the water mist condensing into water droplets again in the atomizing chamber 210. This design not only reduces the noise generated by the dripping water droplets, but also increases the mist output of the atomizing device 200 and reduces energy consumption.

[0084] In some further embodiments, in the height direction, the connection between the first portion 2141 and the mist outlet 2121 is arranged opposite to the third portion 2143 .

[0085] Through the above technical solution, water droplets dripping from the inner wall of the mist outlet 2121 on the side close to the first part 2141 can drip onto the third part 2143 instead of dripping onto the liquid surface, effectively reducing the noise caused by the dripping water droplets.

[0086] 7 , 8 and 9 , in some embodiments, the atomization chamber 210 includes a first top wall 2122 located directly above the atomization element 22 , the first top wall 2122 being connected to the first side wall 214 , and the first top wall 2122 being formed as an inclined surface extending downward and in a direction away from the mist outlet 2121 .

[0087] The above technical solution sets the first top wall 2122 as an inclined surface, so that the water droplets condensed on the first top wall 2122 can flow to the side wall of the atomizing chamber 210 and finally flow into the liquid surface, avoiding the situation where the water droplets condensed on the first top wall 2122 directly drip, thereby reducing the noise of the atomizing device 200.

[0088] 5 , 6 and 7 , in some embodiments, the atomizing device 200 further includes a fan 23 , which sends air toward the mist outlet 2121 .

[0089] Through the above technical solution, when the atomizing device 200 is working, the atomizing element 22 atomizes the liquid while the fan 23 continuously supplies air to the mist outlet 2121, so that the generated water mist can be quickly blown to the mist outlet 2121 to be discharged into the room, thereby accelerating the mist discharge effect of the atomizing device 200 and reducing the probability of the water mist staying in the atomizing chamber 210 and condensing into water droplets again, thereby reducing the noise of the atomizing device 200.

[0090] It should be noted that the fan 23 can be set at a distance from the casing 21, and the fan 23 is connected to the atomizing chamber 210 through a pipe to supply air toward the mist outlet 2121; the fan 23 can also be set in the casing 21, and the air outlet 311 of the fan 23 is connected to the atomizing chamber 210 to supply air toward the mist outlet 2121, as long as the fan 23 can supply air toward the mist outlet 2121.

[0091] When the atomizing device 200 is an independent product, the atomizing device 200 itself may include the fan 23 . When the atomizing device 200 is part of another product, the atomizing device 200 may also be connected to the fan 23 of the product to blow the mist out of the mist outlet 2121 .

[0092] In some embodiments, the fan 23 is disposed in the housing 21 to shorten the distance between the air outlet of the fan 23 and the atomizing chamber 210 , thereby reducing wind loss.

[0093] 6 , 7 and 8 , in some embodiments, the housing 21 is provided with a holding chamber 216 for placing the fan 23 , the holding chamber 216 is provided with an air inlet area and an air outlet area 2161 , and a connecting air duct 217 for connecting the air outlet area 2161 and the atomization chamber 210 is provided in the housing 21 .

[0094] By placing the fan 23 in a specially provided containing chamber 216 , the probability of liquid or water mist contacting the fan 23 is reduced, that is, the risk of short circuit of the fan 23 is reduced, and the service life of the fan 23 is extended.

[0095] 8 , 10 and 11 , in some specific embodiments, the air outlet area 2161 of the containing chamber 216 is connected to the upper portion of the connecting air duct 217 , further reducing the risk of liquid entering the containing chamber 216 and contacting the fan 23 .

[0096] 8 , in some embodiments, the air outlet end of the connecting air duct 217 is provided with an air outlet opening 2171 connected to the atomizing chamber 210, and the opening area of ​​the air outlet opening 2171 is smaller than the cross-sectional area of ​​the air outlet end, so that the wind in the connecting air duct 217 can be smoothly blown out from the air outlet opening 2171 without allowing the gas to flow back. In this way, the mist inside the atomizing chamber 210 will not enter the connecting air duct 217, thereby controlling the generation of condensation water in the connecting air duct 217 and further reducing the risk of liquid contacting the fan 23.

[0097] 8 , in some specific embodiments, a windshield 2123 extending downward is provided at the top of the connecting air duct 217 , and a lower end of the windshield 2123 is spaced apart from the bottom wall of the connecting air duct 217 to define an air outlet opening 2171 .

[0098] The structure of the air outlet opening 2171 formed in the above technical solution is simple, easy to process, and reduces the cost of the atomizing device 200.

[0099] 6, 7, and 8, in some embodiments, the housing 21 includes a base 211 and a top cover 212. The atomizer 22 is disposed on the bottom wall of the base 211, and the top cover 212 is disposed on the top of the base 211. The top cover 212 is provided with a mist outlet 2121 and a sound-absorbing structure. An atomization chamber 210 and a connecting air duct 217 are defined between the base 211 and the top cover 212.

[0100] The above technical solution defines the atomizing chamber 210 and the connecting air duct 217 by the two separate structures of the base 211 and the top cover 212, which reduces the difficulty of mold opening and reduces costs. It also facilitates the installation, maintenance and cleaning of the internal structure of the inner atomizing chamber 210.

[0101] 6 , 7 and 8 , in some specific embodiments, a top cover 212 is provided above the base 211 , and the top cover 212 is provided on the base 211 , and a windshield 2123 extending toward the base 211 is provided inside the top cover 212 . During assembly, the top cover 212 , the windshield 2123 and the base 211 cooperate with each other to define the atomizing chamber 210 and the connecting air duct 217 , and the atomizing element 22 is provided in the atomizing chamber 210 , and the air outlet area 2161 is connected to the inner wall of the upper part of the connecting air duct 217 , and the atomizing chamber 210 and the connecting air duct 217 are separated by the windshield 2123 , so that the fan 23 and the atomizing element 22 will not interfere with each other during operation, thereby ensuring the normal use of the atomizing device 200 . The top cover 212 is further provided with a mist outlet 2121, which is in communication with the atomizing chamber 210. The water mist generated by the atomizing element 22 can flow out of the mist outlet 2121 under the action of the fan 23. At the same time, when the atomizing device 200 is working, the water mist generated by the atomizing element 22 will only move within the atomizing chamber 210. Due to the obstruction of the windshield 2123, the water mist cannot directly enter the connecting air duct 217. The drifting water mist can only move within the atomizing chamber 210. The water mist moving toward the connecting air duct 217 will adhere to the windshield 2123 after contacting it. The water mist attached to the windshield 2123 condenses into water droplets and then flows to the liquid surface again without entering the connecting air duct 217. The provision of the windshield 2123 and the connecting air duct 217 reduces the risk of water mist contacting the fan 23, improves the safety of the fan 23, and further improves the safety of the atomizing device 200.

[0102] In some embodiments, the base 211 and the top cover 212 can be connected by multiple fasteners (screws or bolts), providing a reliable connection. In other embodiments, the base 211 and the top cover 212 can also be detachably connected using a snap-fit ​​structure, which also facilitates later maintenance or replacement. Other situations are also possible, as long as the base 211 and the top cover 212 are detachably connected.

[0103] 6 , 7 and 8 , in some specific embodiments, a first sealing ring 218 is provided between the base 211 and the top cover 212 to reduce the possibility of leakage of liquid and mist in the atomizing chamber 210 and ensure the reliability of the atomizing device 200 .

[0104] 6 , 7 and 8 , in some embodiments, the housing 21 further includes an outer cover 213 . The outer cover 213 is disposed at the bottom of the base 211 and defines a receiving cavity 216 with the base 211 .

[0105] Through the above technical solution, the holding chamber 216 is defined by the two separate structures of the base 211 and the outer cover 213, which reduces the difficulty of mold opening and reduces costs. It also facilitates the installation, maintenance and cleaning of the fan 23 in the inner holding chamber 216.

[0106] In some embodiments, the base 211 and the outer cover 213 can be connected by multiple fasteners (screws or bolts), providing a secure connection. In other embodiments, the base 211 and the outer cover 213 can be detachably connected using a snap-fit ​​structure, further facilitating later repair or replacement. Other configurations are also possible, as long as the base 211 and the outer cover 213 are detachably connected.

[0107] 6 , 7 and 8 , in some embodiments, the atomizing device 200 further includes a water tank 219 , the bottom of which is detachably connected to the housing 21 and communicated with the atomizing chamber 210 , and the water tank 219 is suitable for replenishing liquid into the atomizing chamber 210 to extend the single usable time of the atomizing device 200 .

[0108] A specific embodiment of the present application is described below with reference to Figures 5-10.

[0118] The atomizing device 200 further includes a fan 23 , which is disposed in the housing 21 and blows air toward the mist outlet 2121 .

[0119] The housing 21 is provided with a receiving chamber 216 for accommodating the fan 23 . The receiving chamber 216 is provided with an air inlet area and an air outlet area 2161 . A connecting air duct 217 is provided in the housing 21 for connecting the air outlet area 2161 and the atomizing chamber 210 .

[0120] The air outlet area 2161 of the containing chamber 216 is connected to the upper portion of the connecting air duct 217 .

[0121] The air outlet end of the connecting air duct 217 is provided with an air outlet opening 2171 communicating with the atomizing chamber 210 . The opening area of ​​the air outlet opening 2171 is smaller than the cross-sectional area of ​​the air outlet end.

[0122] A windshield plate 2123 extending downward is provided at the top of the connecting air duct 217 . The lower end of the windshield plate 2123 is spaced apart from the bottom wall of the connecting air duct 217 to define an air outlet opening 2171 .

[0123] The housing 21 includes a base 211 and a top cover 212. The atomizer 22 is located on the bottom wall of the base 211, and the top cover 212 is located on the top of the base 211. The top cover 212 is provided with a mist outlet 2121 and a sound-absorbing structure. The base 211 and the top cover 212 define an atomizing chamber 210 and a connecting air duct 217.

[0124] The base 211 and the top cover 212 may be connected by a plurality of screws.

[0125] A first sealing ring 218 is provided between the base 211 and the top cover 212 for sealing.

[0126] The housing 21 further includes an outer cover 213, which is disposed at the bottom of the base 211 and defines a receiving chamber 216 between the outer cover 213 and the base 211. The base 211 and the outer cover 213 may be connected by a plurality of screws.

[0127] The atomizing device 200 further includes a water tank 219 . The bottom of the water tank 219 is detachably connected to the housing 21 and communicates with the atomizing chamber 210 .

[0128] 12 to 19, according to one embodiment of the present application, the atomizing device 200 includes a housing 21, an atomizing element 22, an air outlet 2114, and a windshield 2123. The interior of the housing 21 is formed with a receiving cavity and a mist outlet 2121 connected to the receiving cavity. A water tank 2111 is provided at the bottom of the housing 21; the atomizing element 22 is provided in the water tank 2111, and the atomizing element 22 is used to excite the liquid in the water tank 2111 into a mist; the air outlet 2114 is provided at A receiving chamber for placing a fan is formed inside the casing 21 and the air outlet portion 2114, and an air outlet area 2161 of the air outlet portion 2114 is located in the receiving chamber; the wind shield 2123 is arranged in the casing 21 and divides the receiving chamber into an atomizing chamber 210 and a connecting air duct 217, the atomizing element 22 and the air outlet portion 2114 are respectively located in the atomizing chamber 210 and the connecting air duct 217, and an air outlet opening 2171 is formed on the wind shield 2123 to connect the atomizing chamber 210 with the connecting air duct 217.

[0129] According to the atomizing device 200 of the present application, a housing 21 is provided. A water tank 2111 is machined at the bottom of the housing 21 for holding water. An atomizing element 22 is provided in the water tank 2111. When the atomizing device 200 is in operation, the atomizing element 22 can stimulate the water in the water tank 2111 to form a mist. During the process of drifting, the mist contacts the inner wall of the water tank 2111 to form condensed water, which can then flow back into the water tank 2111. The provision of the water tank 2111 can collect and aggregate the mist remaining inside the atomizing device 200 for secondary use, thereby improving the humidification efficiency of the atomizing device 200. An air outlet 2114 is also provided in the housing 21. The air outlet 2114 can discharge air toward the top of the water tank 2111, so that the mist stimulated by the atomizing element 22 can be blown out of the atomizing device 200 through the mist outlet 2121 on the housing 21, thereby achieving the humidification effect of the atomizing device 200.

[0130] A windshield 2123 is also provided in the casing 21. The windshield 2123 is provided in the casing 21 and divides the accommodating chamber into an atomizing chamber 210 and a connecting air duct 217. The atomizing element 22 is provided in the atomizing chamber 210, and the air outlet portion 2114 is provided in the connecting air duct 217. The atomizing chamber 210 and the connecting air duct 217 are separated by the windshield 2123, so that the air outlet portion 2114 and the atomizing element 22 will not interfere with each other during operation, thereby ensuring the normal use of the atomizing device 200. When the atomizing device 200 is operating, the water mist generated by the atomizing element 22 moves only within the atomizing chamber 210. Due to the obstruction of the windshield 2123, the water mist cannot directly enter the connecting air duct 217. The scattered water mist can only move within the atomizing chamber 210. After the water mist moves toward the connecting air duct 217, it will adhere to the windshield 2123 after contacting it and form condensed water. The condensed water will flow back to the water tank 2111 along the windshield 2123. The provision of the windshield 2123 prevents the air outlet 2114 in the connecting air duct 217 from being affected by the water mist, reduces the possibility of condensed water infiltrating the connecting air duct 217, prevents the air outlet 2114 from being corroded by the condensed water, improves the safety of the air outlet 2114, and thereby improves the safety of the atomizing device 200. In addition, the windshield 2123 blocks water mist and condensed water from entering the air duct 217, which can improve the cleanliness of the air duct 217 and prevent the water mist blown out by the atomizing device 200 from being contaminated.

[0131] During assembly, the atomizing device 200 can be provided with an air outlet opening 2171 on the wind shield 2123. The air outlet opening 2171 can connect the atomizing chamber 210 and the connecting air duct 217. The wind blown out by the air outlet part 2114 enters the atomizing chamber 210 through the air outlet opening 2171 and can blow out the water mist stimulated by the atomizing element 22 through the mist outlet 2121. The structure of the air outlet opening 2171 enables the atomizing device 200 to discharge the water mist normally to realize the humidification function.

[0132] According to the atomizing device 200 of the present application, a windshield 2123 is provided in the housing 21. The windshield 2123 cooperates with the housing 21 to define the atomizing chamber 210 and the connecting air duct 217. The atomizing element 22 is provided in the atomizing chamber 210 and can stimulate the water in the water tank 2111 located in the atomizing chamber 210 into mist. The air outlet portion 2114 discharges air toward the atomizing chamber 210 in the connecting air duct 217 to blow the water mist out through the mist outlet 2121. The windshield 2123 can block the water mist stimulated by the atomizing element 22 from entering the connecting air duct 217, preventing the water mist from flowing back, and can slow down the secondary pollution caused by the condensed water formed by the water mist penetrating into the connecting air duct 217, protecting the air outlet portion 2114 from being damaged by the water mist and condensed water, thereby improving the safety of the atomizing device 200.

[0133] In some embodiments, the fan can be directly assembled in the air outlet 2114 . In this case, the fan is located in the casing 21 .

[0134] In other embodiments, the fan may also be installed outside the housing 21. In this case, the fan is only connected to the air duct in the air outlet portion 2114 through the ventilation pipe.

[0135] According to one embodiment of the present application, the casing 21 includes a base 211 and a top cover 212, and the base 211 is provided with a water tank 2111 and an air outlet 2114; the top cover 212 is covered on the base 211, and the top cover 212 is formed with a wind shield 2123 extending toward the base 211 and a mist outlet 2121 connecting the atomization chamber 210. Specifically, the housing 21 is provided with a base 211 and a top cover 212. When assembled, the top cover 212 is covered on the base 211 to form a receiving cavity. The windshield 2123 is connected to the top cover 212 and extends toward the base 211, so that the air outlet opening 2171 is located at the bottom of the windshield 2123 and close to the base 211. The air blown out by the air outlet portion 2114 flows out from the connecting air duct 217 and enters the atomizing chamber 210 through the air outlet opening 2171. The air entering the atomizing chamber 210 can blow the water mist in the atomizing chamber 210 out through the mist outlet 2121. The air outlet opening 2171 is arranged at a position close to the base 211 to facilitate airflow pressurization, accelerate the flow rate of the airflow in the atomizing chamber 210, and thereby improve the air outlet efficiency of the atomizing device 200.

[0136] In some embodiments, the wind shield 2123 may also be disposed on the base 211 and extend toward the top cover 212 . In this case, the air outlet 2171 is located between the wind shield 2123 and the top cover 212 .

[0137] Since the atomizing chamber 210 and the connecting air duct 217 are connected through the air outlet opening 2171 , when air is discharged, the water mist in the atomizing chamber 210 may flow back into the connecting air duct 217 through the air outlet opening 2171 .

[0138] According to one embodiment of the present application, the cross-sectional area of ​​the air outlet opening 2171 is smaller than the cross-sectional area of ​​the connecting air duct 217. As shown in FIG17 , the cross-sectional area of ​​the air outlet opening 2171 can be understood as the area of ​​the cross section of the air outlet opening 2171 in the direction of the connecting air duct 217 toward the atomizing chamber 210. The cross-sectional area of ​​the air outlet opening 2171 is the area of ​​the channel formed between the cross section where S1 is located in FIG17 and the top cover 212 and the base 211. Similarly, the cross-sectional area of ​​the connecting air duct 217 can be understood as the area of ​​the cross section of the connecting air duct 217 in the direction toward the atomizing chamber 210. The cross-sectional area of ​​the connecting air duct 217 is the area of ​​the channel formed between the cross section where S2 is located in FIG17 and the top cover 212 and the base 211. S1 < S2. The atomizing device 200 can avoid wind backflow by setting the cross-sectional area of ​​the air outlet opening 2171 to be smaller than the cross-sectional area of ​​the connecting air duct 217, ensuring that the water mist in the atomizing chamber 210 will not enter the air outlet portion 2114 through the connecting air duct 217, thereby ensuring the safety of the air outlet portion 2114.

[0139] In some embodiments, the cross-sectional area of ​​the air outlet 2171 may also be larger than the cross-sectional area of ​​the mist outlet 2121 . Such a setting scheme can speed up the flow rate of the water mist at the mist outlet 2121 and improve the humidification efficiency of the atomizing device 200 .

[0140] According to one embodiment of the present application, the air outlet portion 2114 is formed with an air outlet area 2161, which is open in a direction away from the windshield 2123, in a direction away from the windshield 2123, or toward the top of the top cover 212. Since the air outlet portion 2114 is disposed within the connecting air duct 217 and can supply air to the atomizing chamber 210, the air outlet direction of the air outlet portion 2114 affects the use of the atomizing device 200.

[0141] During processing, the atomizing device 200 can set an air outlet area 2161 on the air outlet portion 2114 for air outlet. When the air outlet portion 2114 is assembled to the connecting air duct 217, the direction of the air outlet area 2161 can be open in the direction away from the wind shield 2123; or the air outlet area 2161 can be open in the direction deviating from the wind shield 2123. The deviation here can be understood as the air outlet area 2161 can be open on both sides of the width direction of the air outlet portion 2114; or the air outlet area 2161 can be open toward the top of the top cover 212. The setting of the air outlet direction can avoid the air outlet area 2161 and the air outlet opening 2171 from being at least partially opposite each other. If the air outlet area 2161 is directly toward the wind shield 2123, it is easy for the air outlet area 2161 and the air outlet opening 2171 to be opposite each other. When the connecting air duct 217 discharges air toward the atomization chamber 210, the floating water mist can easily move to the position of the air outlet opening 2171. At this time, the part where the air outlet opening 2171 and the air outlet area 2161 are not intertwined can easily suck the water mist into the connecting air duct 217, thereby affecting the safety of the air outlet portion 2114 and the cleanliness level in the connecting air duct 217. The solution in which the air outlet area 2161 is open in a direction away from the wind shield 2123 or in a direction deviating from the wind shield 2123 or toward the top cover 212 can not only avoid the situation in which the air outlet area 2161 and the air outlet opening 2171 are at least partially opposite each other, but also extend the distance from the air outlet area 2161 to the air outlet opening 2171, further reducing the possibility of water mist entering the air outlet portion 2114, thereby ensuring the safety of the air outlet portion 2114.

[0142] According to one embodiment of the present application, a limiting protrusion 2115 is formed on the air outlet portion 2114, and the top surface of the limiting protrusion 2115 is adapted to abut against the windshield 2123. The limiting protrusion 2115 can be provided on the air outlet portion 2114. During assembly, the windshield 2123 can cooperate with the limiting protrusion 2115 to abut against it. The limiting protrusion 2115 can support the windshield 2123. Furthermore, since the windshield 2123 is disposed within the top cover 212, the abutment between the limiting protrusion 2115 and the windshield 2123 can improve the stability of the assembly between the top cover 212 and the base 211. During actual manufacturing, the limiting protrusion 2115 can also be machined into a groove that mates with the windshield 2123. The edge of the windshield 2123 facing the limiting protrusion 2115 can be snapped into the groove of the limiting protrusion 2115, further improving the stability of the assembly between the windshield 2123 and the base 211. In addition, the provision of the limiting protrusion 2115 can also improve the sealing performance when the wind shield 2123 is assembled with the housing 21 , thereby reducing the possibility of condensed water on the wind shield 2123 penetrating into the connecting air duct 217 .

[0143] According to one embodiment of the present application, the atomizing device 200 further includes a water tank 219, which is detachably mounted on the housing 21. The water tank 219 defines a water storage chamber, which, when mounted on the housing 21, communicates with the water tank 2111. Because the water tank 2111 can hold a limited amount of water, the atomizing device 200 requires additional structure for replenishing the water tank 2111. The atomizing device 200 further includes a water tank 219, which, when assembled, is detachably mounted on the housing 21. The water tank 219 defines a water storage chamber, which can hold more water than the water tank 2111. When the water tank 219 is assembled with the housing 21, the water storage chamber communicates with the water tank 2111, allowing water in the water storage chamber to flow into the water tank 2111 to replenish the water tank 2111 and increase the operating time of the atomizing device 200. When the water in the water storage chamber is exhausted, the water tank 219 can be directly removed to refill the water storage chamber. After the refilled water tank 219 is reassembled into the housing 21, the atomizing device 200 can resume operation without opening the water tank 2111, which can effectively improve the water replenishment efficiency of the atomizing device 200. In addition, if the atomizing device 200 is assembled into other equipment, the water tank 219 can also be directly connected to an external water source according to actual conditions, eliminating the need to disassemble the water tank 219 and further improving the water replenishment efficiency.

[0144] According to one embodiment of the present application, the housing 21 includes a base 211, which is provided with a water tank 2111 and a water replenishment chamber 2112 connected to the water tank 2111. The water outlet 2191 of the water tank 219 is disposed in the water replenishment chamber 2112. Since the water tank 219 is used to replenish the water tank 2111, the structure of the water tank 219 may affect the replenishment of the water tank 2111. During processing, the water outlet 2191 can be provided on the water tank 219, and the water replenishment chamber 2112 can be provided on the base 211. When the water tank 219 and the base 211 are assembled, the water outlet 2191 can be accommodated in the water replenishment chamber 2112, thereby preventing water from flowing out of the gap between the base 211 and the water tank 219 during replenishment. The water replenishment chamber 2112 is connected to the water tank 2111. Water flowing into the water replenishment chamber 2112 from the water outlet 2191 can flow directly into the water tank 2111 to replenish the water. During actual assembly, a valve body structure to control the flow of water can be installed in the water outlet 2191 or the water replenishment chamber 2112 to adjust the water replenishment according to actual needs. The structure of the water replenishment chamber 2112 reserves space for the subsequent assembly of the control structure.

[0145] According to one embodiment of the present application, the air outlet 2114 is disposed between the water tank 2111 and the water replenishment chamber 2112. A connecting passage 2113 is formed on the base 211, connecting the water replenishment chamber 2112 and the water tank 2111. The connecting passage 2113 passes through the air duct 217. Since the air outlet 2114, the water tank 2111, and the water replenishment chamber 2112 are all disposed on the base 211, the arrangement of the air outlet 2114, the water tank 2111, and the water replenishment chamber 2112 affects the water replenishment and air outlet of the atomizing device 200. Specifically, the air outlet 2114 is arranged in the connecting air duct 217, and the connecting air duct 217 is located between the water tank 2111 and the water replenishing chamber 2112. It can also be understood that the air outlet 2114 is arranged between the water tank 2111 and the water replenishing chamber 2112. The arrangement of the air outlet 2114, the water tank 2111 and the water replenishing chamber 2112 improves the compactness of the structure of the atomizing device 200. In addition, a connecting channel 2113 is provided on the base 211, and the connecting channel 2113 connects the water replenishment chamber 2112 with the water tank 2111. The setting of the connecting channel 2113 can drain the water in the water replenishment chamber 2112 into the water tank 2111. When the atomizing device 200 is assembled, the air outlet opening 2171 and the connecting air duct 217 are located above the connecting channel, and the air outlet path and the water replenishment path do not interfere with each other. The overlapping setting of the connecting air duct 217 and the connecting channel 2113 can further improve the compactness of the atomizing device 200.

[0146] According to one embodiment of the present application, the atomizing device 200 further includes a water level monitoring device 24, which is disposed in the water replenishing chamber 2112 and is adapted to detect the water level in the water replenishing chamber 2112. Since the remaining amount of water in the water tank 2111 or the water tank 219 cannot be directly viewed during operation of the atomizing device 200, it is impossible to replenish water in advance. During assembly, the atomizing device 200 can be provided with a water level monitoring device 24 in the water replenishing chamber 2112 to facilitate real-time detection of the water level in the water replenishing chamber 2112. Since the water replenishing chamber 2112 and the water tank 2111 are directly connected through the connecting channel 2113, the water levels in the water replenishing chamber 2112, the water tank 2111 and the connecting channel 2113 are the same when there is sufficient water in the water storage chamber. When the water in the water storage chamber is insufficient, the water in the water tank 2111 will slowly decrease, and the water in the water replenishing chamber 2112 and the connecting channel 2113 will be exhausted. The water level monitoring device 24 will give feedback to prompt the water tank 219 that water replenishment is needed. At this time, the water level in the water tank 2111 is lower than the connecting channel 2113, but there is still water. The atomizing device 200 can continue to be used.
