Detailed Description of the Invention

[0040] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention 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 should not be construed as a limitation to the present invention. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0042] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0043] The inventor analyzed the ultrasonic humidifier 100 in the related technology and found that the noise generated by it mainly comes from three aspects. One is the pneumatic noise emitted by the fan 23 and its air flow channel; the second is the water droplet sound caused by the water droplets falling onto the water surface; the third is the collision sound of the water droplets hitting the inner wall of the ultrasonic humidifier 100. The latter two are collectively referred to as water sound. Since the first kind of sound has been solved relatively ideally at present, the present invention is dedicated to solving the latter two kinds of sounds, that is, the water sound.

[0044] The principle of the ultrasonic humidifier 100 is shown in Figure 1 , the high-frequency oscillation plate 11 transfers energy to water, and a water column 12 is excited in the center of the oscillation sheet, breaking through the liquid surface and rising to a certain height. Then, due to the rupture of the bubbles inside the water column 12, the water mass is exploded. Among them, a small part of the water mass particles are relatively small and form 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.

[0045] After the central water mass explodes, a small part of the water mass particles are small and form mist, while most of the water mass forms water droplets flying out in all directions and upward, as shown in Figure 2The water droplets flying out in all directions are of different sizes. If the atomization chamber is large enough, these water droplets will fly back to the water surface, which is one of the sources of the water droplet sound (the first type of water sound). The water droplets shooting straight up from the center lose their kinetic energy after rising to a certain height and will fall vertically back to the water surface again. This part will collide with the water column 12 rushing up from the bottom. The actual state presented is that the water column 12 above the ultrasonic generator is intermittent. Sometimes, before the rising water column 12 breaks through the water surface, the water droplets falling from the center have already dripped onto the water surface. This is the second reason for the generation of the water droplet sound (the second type of water sound).

[0046] Due to some external factors, such as space requirements and cost considerations, the size of the atomization chamber is restricted to a certain extent, as shown in Figure 3 , at this time, the flying water masses around and the central water mass may directly splash onto the inner wall of the atomization chamber. This is also one of the sources of the water sound (the third type of water sound).

[0047] as shown in Figure 4 , since the inside of the atomization chamber is filled with water mist, water droplets will gradually condense on the inner wall. When the water droplets condensed on the side wall accumulate to a certain extent, under the action of gravity, they will slide down along the side wall into the water by themselves. This kind of entry into the water is slow and silent. The water droplets condensed on the top surface will gather larger and larger until they drip from the top surface. This is also one of the sources of the water droplet sound (the fourth type of water sound).

[0048] Based on the above research, the inventor proposes an atomization device 200 to improve the noise pollution during the operation of the atomization device 200.

[0049] Next, refer to Figures 5 - 13 to describe the atomization device 200 according to an embodiment of the present invention.

[0050] Refer to Figure 5 , Figure 6 and Figure 7 , the atomization device 200 according to an embodiment of the present invention includes: a housing 21 and an atomization member 22. The housing 21 defines an atomization chamber 210, and the atomization member 22 is disposed at the bottom of the atomization chamber 210. When the atomization device 200 operates, liquid is added into the atomization chamber 210 so that the liquid covers the atomization member 22. The atomization member 22 is adapted to transfer energy to the liquid in the atomization chamber 210, and a water column breaking through the liquid surface is excited in the center of the atomization member 22. The tail section of the water column starts to diverge, forming water droplets and water mist. An air outlet 2121 is provided at the top of the atomization chamber 210, and the mist in the atomization chamber 210 can be discharged into the room through the air outlet 2121 to improve the indoor environment.

[0051] In order to improve the noise pollution generated during the operation of the atomization device 200, in the embodiments of the present invention, the atomization chamber 210 is provided with a first side wall 214, and the first side wall 214 is configured with a sound-absorbing structure that contacts the liquid to eliminate the water sound. The atomizing member 22 is inclined relative to the horizontal plane and is used to generate water mist toward the first side wall 214.

[0052] For the atomization device 200 according to the embodiments of the present invention, by arranging the atomizing member 22 to be inclined relative to the horizontal plane, the water column excited by the atomizing member 22 is ejected obliquely, and the water mass does not explode significantly, avoiding the noise (the second water sound) generated when the water droplets that drop in the center in the related art fall on the water surface. And it makes the water column shoot toward the first side wall 214, and the water droplets after the water column explodes can be sprinkled on the first side wall 214 to be sound-absorbed by the sound-absorbing structure of the first side wall 214, avoiding the noise (the first water sound) generated when the water droplets flying around in the related art fall on the water surface. At the same time, it also improves the noise (the third water sound) generated when the water droplets are sprinkled on the inner wall of the atomization chamber 210 in the related art through the sound-absorbing structure. The atomization device 200 proposed by the present invention effectively reduces the noise generated during the operation of the atomization device 200 through the above technical solutions.

[0053] In some specific embodiments, the atomizing end of the atomizing member 22 is inclined relative to the horizontal plane toward the first side wall 214. When the atomizing member 22 operates, a water column perpendicular to the atomizing end is formed at the atomizing end. The atomizing end is inclined relative to the horizontal plane toward the first side wall 214 so that the water column can shoot toward the first side wall 214, ensuring that the water droplets can be sprinkled on the first side wall 214 for sound absorption.

[0054] Refer to Figure 6 、 Figure 7 and Figure 10 In some embodiments, the sound-absorbing structure includes a sound-absorbing material member 215 provided on the inner wall of the atomization chamber 210 and having sound-absorbing voids, so that the water droplets shooting toward the first side wall 214 can fall on the sound-absorbing material member 215. Through the sound absorption of the sound-absorbing material member 215 having sound-absorbing voids, the water sound is effectively reduced. And this technical solution is simple and convenient for obtaining materials. For example, the sound-absorbing material member 215 can be a sponge, effectively reducing the cost of the atomization device 200.

[0055] In some embodiments, the sound-absorbing material member 215 is bonded to the first side wall 214; in other embodiments, the sound-absorbing material member 215 can also be snap-connected or fixed to the first side wall 214 by screws to facilitate the replacement of the sound-absorbing material member 215.

[0056] Refer to Figure 11, in some other embodiments, the sound-absorbing structure can also be the curved surface 2144. After the water column impacts the curved surface 2144 at a small angle a, the downward flowing water adheres to the curved surface 2144 and flows along both the tangential direction and the downward direction 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 sound-absorbing structure of the curved surface 2144 is also convenient for cleaning, reducing the cleaning cost of the atomization device 200.

[0057] In some specific embodiments, the curved surface 2144 is formed as an arc surface that curves away from the center of the atomization chamber 210. This arc surface has a simple structure and is easy to process, reducing the cost of the atomization device 200.

[0058] In some other embodiments, the sound-absorbing structure can also be an inclined surface. After the water column impacts the inclined surface at a small angle a, the downward flowing water adheres to the inclined surface and flows along both the horizontal direction and the downward direction of the inclined surface, effectively reducing the noise when the water droplets contact the inner wall of the atomization chamber 210. At the same time, the sound-absorbing structure of the inclined surface is also convenient for cleaning, reducing the cleaning cost of the atomization device 200.

[0059] Refer to Figure 7 、 Figure 8 and Figure 9 , in some embodiments, the first side wall 214 includes: a first part 2141 and a second part 2142. In the height direction, the first part 2141 is located above the second part 2142, and the first part 2141 extends obliquely toward a direction away from the center line of the mist outlet 2121, and at least a part of the second part 2142 is configured as a sound-absorbing structure.

[0060] Because some of the mist in the atomization chamber 210 will condense into water droplets on the inner wall of the atomization chamber 210, the above technical solution sets the first part 2141 as an inclined surface, so that the water droplets condensed on the first part 2141 can flow to the sound-absorbing structure of the second part 2142, avoiding the situation where the water droplets condensed on the first part 2141 directly drip, thereby reducing the noise of the atomization device 200.

[0061] Refer to Figure 7 、 Figure 8 and Figure 10 , in some further embodiments, the first side wall 214 further includes a third part 2143. The third part 2143 is located at the lower end of the second part 2142, and the third part 2143 is formed as an inclined surface that extends obliquely downward and toward the center line of the mist outlet 2121.

[0062] In the above technical solution, by setting the third part 2143 as an inclined plane, the water on the second part 2142 can flow along the third part 2143 into the liquid surface, slowing down the flowing speed of the water flow, thereby achieving the effect of reducing the water sound. Moreover, the inclined third part 2143 can also separate the second part 2142 from the liquid surface in the horizontal direction, further reducing the possibility of water droplets directly dripping onto the liquid surface, effectively reducing the noise of the atomizing device 200.

[0063] Referring to Figure 7 , Figure 8 and Figure 9 , in some embodiments, the mist outlet 2121 is arranged at a position close to the first side wall 214.

[0064] In the embodiments of the present invention, water droplets explode to generate water mist at a position close to the first side wall 214. By arranging the mist outlet 2121 at a position close to the first side wall 214, the generated water mist can be quickly discharged through the mist outlet 2121, reducing the risk of the water mist condensing into water droplets again in the atomizing chamber 210. Through this design, not only the noise generated by the dripping water droplets is reduced, but also the mist output of the atomizing device 200 is increased, and the energy consumption is reduced.

[0065] In some further embodiments, in the height direction, the connection between the first part 2141 and the mist outlet 2121 is arranged opposite to the third part 2143.

[0066] Through the above technical solution, the water droplets dripping on the inner wall of the side of the mist outlet 2121 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.

[0067] Referring to Figure 7 , Figure 8 and Figure 9 , in some embodiments, the atomizing chamber 210 includes a first top wall 2122 located directly above the atomizing member 22. The first top wall 2122 is connected to the first side wall 214, and the first top wall 2122 is formed as an inclined plane that slopes downward and extends in a direction away from the mist outlet 2121.

[0068] In the above technical solution, by setting the first top wall 2122 as an inclined plane, 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.

[0069] Referring to Figure 5 , Figure 6 and Figure 7, in some embodiments, the atomizing device 200 further includes a blower 23, and the blower 23 blows air towards the mist outlet 2121.

[0070] Through the above technical solution, when the atomizing device 200 is working, while the atomizing member 22 atomizes the liquid, the blower 23 continuously blows air towards the mist outlet 2121, so that the generated water mist can be quickly blown towards the mist outlet 2121 and discharged into the room, accelerating the mist output effect of the atomizing device 200, reducing the probability that the water mist stays in the atomizing chamber 210 and condenses into water droplets again, and thus reducing the noise of the atomizing device 200.

[0071] It should be noted that the blower 23 can be arranged at an interval from the casing 21, and the blower 23 is communicated with the atomizing chamber 210 through a pipeline to blow air towards the mist outlet 2121; the blower 23 can also be arranged on the casing 21, and the air outlet 311 of the blower 23 is communicated with the atomizing chamber 210 to blow air towards the mist outlet 2121, as long as the blower 23 can blow air towards the mist outlet 2121.

[0072] When the atomizing device 200 is an independent product, the atomizing device 200 itself may include the blower 23. When the atomizing device 200 is a part of other products, the atomizing device 200 can also be communicated with the blower 23 of the product to blow the mist out of the mist outlet 2121.

[0073] In some embodiments, the blower 23 is arranged on the casing 21, shortening the distance between the air outlet 311 of the blower 23 and the atomizing chamber 210 and reducing the loss of wind force.

[0074] Refer to Figure 6 、 Figure 7 and Figure 8 , in some embodiments, the casing 21 is provided with a containing cavity 216 for placing the blower 23. The containing cavity 216 is provided with an air inlet area and an air outlet area 2161, and a connecting air duct 217 for communicating the air outlet area 2161 and the atomizing chamber 210 is arranged in the casing 21.

[0075] By placing the blower 23 in the specially provided containing cavity 216, the probability that the liquid or water mist comes into contact with the blower 23 is reduced, that is, the risk of short circuit of the blower 23 is reduced, and the service life of the blower 23 is prolonged.

[0076] Refer to Figure 8 、 Figure 10 and Figure 11 , in some specific embodiments, the air outlet area 2161 of the containing cavity 216 is communicated with the upper part of the connecting air duct 217, further reducing the risk that the liquid enters the containing cavity 216 and comes into contact with the blower 23.

[0077] Refer to Figure 8, in some embodiments, an air outlet opening 2171 communicating with the atomization chamber 210 is provided at the air outlet end of the communication air duct 217. The opening area of the air outlet opening 2171 is smaller than the cross-sectional area of the air outlet end, so that the air in the communication air duct 217 can smoothly blow out from the air outlet opening 2171 without gas backflow. In this way, the mist inside the atomization chamber 210 will not enter the communication air duct 217, thereby controlling the condensation water in the communication air duct 217 and further reducing the risk of liquid contacting the blower 23.

[0078] Refer to Figure 8 , in some specific embodiments, a wind baffle 2123 extending downward is provided at the top of the communication air duct 217. The lower end of the wind baffle 2123 is spaced from the bottom wall of the communication air duct 217 to define the air outlet opening 2171.

[0079] The structure for forming the air outlet opening 2171 in the above technical solution is simple, easy to process, and reduces the cost of the atomization device 200.

[0080] Refer to Figure 6 , Figure 7 and Figure 8 , in some embodiments, the housing 21 includes a base 211 and a top cover 212. The atomization member 22 is provided on the bottom wall of the base 211, the top cover 212 is provided on the top of the base 211, and the top cover 212 is provided with a mist outlet 2121 and a sound absorption structure. An atomization chamber 210 and a communication air duct 217 are defined between the base 211 and the top cover 212.

[0081] Through the above technical solution, the atomization chamber 210 and the communication air duct 217 are defined by the two split structures of the base 211 and the top cover 212, which reduces the mold opening difficulty and the cost. And it is beneficial to the installation, maintenance and cleaning of the internal structure of the atomization chamber 210.

[0082] Refer to Figure 6 , Figure 7 and Figure 8, in some specific embodiments, a top cover 212 is disposed above the base 211. The top cover 212 covers the base 211, and a wind baffle 2123 extending toward the base 211 is provided inside the top cover 212. During assembly, the top cover 212, the wind baffle 2123, and the base 211 cooperate with each other to define an atomization chamber 210 and a communication duct 217. The atomization member 22 is disposed in the atomization chamber 210. The air outlet area 2161 communicates with the inner wall of the upper part of the communication duct 217. The atomization chamber 210 and the communication duct 217 are separated by the wind baffle 2123, so that the fan 23 and the atomization member 22 will not interfere with each other during operation, ensuring the normal use of the atomization device 200. A mist outlet 2121 is further provided on the top cover 212, and the mist outlet 2121 communicates with the atomization chamber 210. The water mist excited by the atomization member 22 can flow out from the mist outlet 2121 under the action of the fan 23. At the same time, when the atomization device 200 is operating, the water mist excited by the atomization member 22 will only move within the atomization chamber 210. Due to the blocking of the wind baffle 2123, the water mist cannot directly enter the communication duct 217. The scattered water mist can only move within the atomization chamber 210. The water mist moving toward the communication duct 217 will adhere to the wind baffle 2123 after contacting the wind baffle 2123. The water mist adhering to the wind baffle 2123 condenses into water droplets and then flows back to the liquid surface and cannot enter the communication duct 217. The settings of the wind baffle 2123 and the communication duct 217 reduce the risk of the water mist contacting the fan 23, improve the safety of the fan 23, and thus improve the safety of the atomization device 200.

[0083] In some embodiments, the base 211 and the top cover 212 can be connected by a plurality of fasteners (screws or bolts), and the connection is reliable. In other embodiments, the base 211 and the top cover 212 can also be detachably connected by a snap structure, which is also beneficial for later maintenance or replacement.
