[0038] Figure 2 This is a schematic diagram of the humidification device of this utility model. Figure 3 for Figure 2 A partial cross-sectional view of the humidification device shown.

[0039] This utility model provides a humidification device 200, see reference. Figure 2 and Figure 3 As shown, it includes a water storage section 210 and a humidification section 220. The water storage section 210 is used to store liquid that generates humidified air. The humidification section 220 is disposed above the water storage section 210.

[0040] In some illustrative embodiments, reference is made to Figure 2 and Figure 3 As shown, the water storage section 210 includes, but is not limited to, being configured as a box-shaped structure, specifically a cube, cylinder, elliptical cylinder, or other box-shaped structures with internal cavities. Specifically, the water storage section 210 has a bottom surface, a wall extending upward from the outer periphery of the bottom surface, and an opening formed by the upper edge of the wall surface on the opposite side of the bottom surface. A drain hole is provided on the bottom surface of the water storage section 210. Furthermore, the liquid stored in the water storage section 210 includes, but is not limited to, water, hypochlorous acid liquid, a mixture of water and vegetable glycerin (such as plant essential oil), and other liquids suitable for humidifying air.

[0041] In some illustrative embodiments, reference is made to Figure 2 and Figure 3 As shown, the water storage section 210 also includes a water-breaking wall 241. The water-breaking wall 241 includes, but is not limited to, being disposed on the inner wall of the water storage section 210, for further breaking down large droplets ejected from the first water absorption section 221 into finer water mist particles after colliding with it, thereby achieving secondary atomization of the liquid.

[0042] Furthermore, the water-breaking wall 241 is made of, but is not limited to, non-toxic, odorless, and flexible materials such as silicone. This material's elastic properties not only help convert the impact kinetic energy of the droplets into tearing and diffusion, improving atomization efficiency, but also provide superior damping and sound absorption, effectively suppressing noise generated by high-speed droplet impacts, thus achieving a synergistic effect of efficient atomization and low-noise operation.

[0043] It should be noted that the humidifier 200 can be used independently to humidify the air, or it can be used in conjunction with other devices.

[0044] For example, refer to Figure 2 As shown, it can be integrated with the filter device 300 on the same frame to further filter at least some of the impurities and / or dust in the humidified air in addition to the humidified air.

[0045] The humidification unit 220 configured in the humidification device 200 described above will be described in detail below with reference to the accompanying drawings.

[0046] First Embodiment

[0047] Figure 4 This is a perspective view of the humidifier section of the first embodiment of the present invention. Figure 5 for Figure 4 The diagram shows a half-section of the humidifier section.

[0048] According to an embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the humidifying unit 220 includes a first water-absorbing part 221, a water-distributing part 222, and a plurality of blades 223. The lower end of the first water-absorbing part 221 is located in the water storage part 210 and is used to draw liquid into the humidifying unit 220. The water-distributing part 222 is connected to the upper end of the first water-absorbing part 221 and has a first inclined surface 2221 extending outward from the first water-absorbing part 221. The plurality of blades 223 are vertically arranged on the water-distributing part 222, and the plurality of blades 223 are arranged at intervals to form a ring-shaped blade group 223, with a channel formed between two adjacent blades 223.

[0049] In some illustrative embodiments, reference is made to Figure 4 and Figure 5 As shown, the water distribution section 222 has an overall funnel-shaped structure, with a first water absorption section 221 disposed in the middle. In detail, the first water absorption section 221 includes, but is not limited to, being configured as a hollow funnel-shaped rotating body, comprising a connected large-diameter end and a small-diameter end; its large-diameter end is integrally formed with the water distribution section 222, while the small-diameter end extends downward and is immersed below the liquid surface of the water storage section 210.

[0050] It should be noted that, in this embodiment, the "lower end of the first water-absorbing part 221" refers to a section extending upward from its bottom surface. When the water storage part 210 contains liquid, this lower end is immersed in the liquid, and the liquid level is not higher than the junction of the large-diameter end and the small-diameter end of the first water-absorbing part 221.

[0051] In some illustrative embodiments, reference is made to Figure 4 and Figure 5As shown, the first water-absorbing part 221 is an integrally formed rotating structure, with its large-diameter end connected to its small-diameter end, and a through hollow pipe formed in the middle. The humidifying part 220 is also provided with a drive fixing part 224, which extends upward from the first water-absorbing part 221, and has an insertion hole in its middle for connecting with the output shaft of the drive part 230, so that the entire humidifying part 220 can rotate synchronously under the torque provided by the output shaft.

[0052] The cross-sectional shape of the insertion hole includes, but is not limited to, being configured as a D-shape to form a tight fit with the output shaft of a corresponding shape, effectively preventing relative rotation. The drive unit 230 may specifically consist of a motor and an output shaft connected to the motor, and its arrangement is flexible, either above or below the first suction unit 221.

[0053] Furthermore, a plurality of water-absorbing rib structures are provided at intervals around the axis (i.e., the output shaft axis) of the inner wall of the small-diameter end of the first water-absorbing part 221 and the drive fixing part 224. When the humidifying part 220 rotates, the water-absorbing rib structure can generate a centrifugal water-absorbing effect similar to an impeller pump, continuously drawing liquid from the small-diameter end and transporting it through the large-diameter end to the first inclined surface 2221 of the water distribution part 222, thereby achieving effective lifting and guiding of the liquid.

[0054] According to an embodiment of the present invention, referring to Figure 5 As shown, the first inclined surface 2221 includes a first side 2222 near the first water-absorbing part 221 and a second side 2223 away from the first water-absorbing part 221, the second side 2223 being higher than the first side 2222.

[0055] According to an embodiment of the present invention, referring to Figure 5 As shown, blade 223 is disposed on the upper end surface of water distribution section 222, and the upper end surface of water distribution section 222 defines a first inclined surface 2221.

[0056] In some illustrative embodiments, reference is made to Figure 4 and Figure 5 As shown, the water distribution section 222 is connected to the large-diameter end of the first water absorption section 221, forming a first inclined surface 2221 that surrounds the first water absorption section 221 and extends outward. In detail, the first inclined surface 2221 extends upward from its first side 2222 (which can be understood as its inner side) close to the first water absorption section 221 to its second side 2223 (which can be understood as its outer side) away from the first water absorption section 221, thereby forming a curved surface that slopes downward from the outer side to the center.

[0057] In a preferred embodiment, in addition to the structure described above, the water distribution section 222 may also be provided with a platform section 2224. This platform section 2224 extends horizontally outward from the second side 2223 of the first inclined surface 2221. This horizontal platform section 2224 expands the air outlet side of the humidification section 220, thereby effectively ensuring the overall humidification capacity of the humidification device 200.

[0058] In this embodiment, the first water-absorbing part 221 of the humidification device 200 uses centrifugal force to draw liquid upward from the water storage part 210 during rotation. After the liquid reaches the connected water distribution part 222, it forms a uniformly accelerated water film along its first inclined surface 2221. At the same time, multiple blades 223 vertically arranged on the water distribution part 222 form an annular blade group 223, which acts as the impeller of a centrifugal fan when rotating, drawing in air from the center and throwing the airflow outward through the channel between the blades 223. This allows the functions of water absorption, water distribution, and blowing to be completed by a single component, which not only eliminates the need for a separate fan and motor, reducing cost and size, but also improves the gas-liquid exchange efficiency by directly and forcibly mixing and atomizing the high-speed airflow with the flowing water film at the blades 223, thus ensuring high-efficiency humidification performance while simplifying the structure.

[0059] According to an embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the humidifier 220 also includes a cover 225. The cover 225 is configured in a ring shape and is disposed at the upper end of the blade 223.

[0060] According to an embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the cover portion 225 includes a connecting portion 2252 and a curved portion 2251. The connecting portion 2252 is connected to the upper end of the blade 223, and the outer edge of the connecting portion 2252 extends to the radially outer side of the blade 223. The curved portion 2251 is disposed on the inner edge of the connecting portion 2252 and is curved upward.

[0061] In some illustrative embodiments, reference is made to Figure 4 and Figure 5 As shown, the humidifying section 220 includes a plurality of arc-shaped blades 223 vertically arranged on the water distribution section 222, preferably an odd number, which helps to reduce noise caused by the resonance of the blades 223. These blades 223 are arranged at intervals around the axis of the humidifying section 220, forming a ring-shaped blade group 223, and the gaps between adjacent blades 223 form channels for air and water to mix and flow out. It should be understood that the embodiments of this utility model are not limited thereto.

[0062] For example, the number of leaves 223 can also be an even number.

[0063] Furthermore, multiple blades 223 extend from near the first water-absorbing part 221 toward the platform part 2224, and are bent in the opposite direction to the rotation direction of the humidifying part 220 when viewed from above. For example, if the humidifying part 220 rotates clockwise under the action of the driving part 230, the blades 223 are bent counterclockwise as a whole; conversely, if the humidifying part 220 rotates counterclockwise, the blades 223 are bent clockwise.

[0064] In terms of specific structure, the side of the blade 223 adjacent to the first water absorption part 221 can be defined as the leading edge 2231, while the side connected to the cover part 225 can be defined as the trailing edge 2232. When the humidification device 200 is working, the rotation direction of the annular blade 223 assembly is opposite to its bending direction. This allows the blade 223 to draw in air from the central region when rotating, and to efficiently throw the gas-liquid mixture outward through the channel by means of centrifugal force, thereby achieving a uniform and efficient humidification effect.

[0065] According to an embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the humidifier 200 also includes a guide shroud 240. The guide shroud 240 is disposed above the humidifier 220 and is configured in a ring shape. An air inlet is formed in the center of the guide shroud 240, and a flow-guiding and pressurizing ring 242 is provided on the inner edge of the guide shroud 240, recessed in a direction away from the humidifier 220. At least a portion of the curved portion 2251 is located within the flow-guiding and pressurizing ring 242.

[0066] The curved portion 2251 effectively prevents water vapor blown out from the humidifier 220 from re-entering the humidifier 220 through the gap between the guide shroud 240 and the cover 225, thus preventing air circuit breakage, crossflow that could lead to noise generation and reduced humidification.

[0067] In some illustrative embodiments, reference is made to Figure 4 and Figure 5 As shown, the humidifier 200 also includes a guide shroud 240 disposed above the humidification section 220. The guide shroud 240 has an umbrella-shaped ring structure with an air inlet in its middle, and a guide pressure boosting ring 242 is disposed at the air inlet. The guide pressure boosting ring 242 protrudes from the edge of the air inlet towards the motor, and its cross-section has an n-shaped concave structure. It can be integrally formed with the guide shroud 240 or manufactured separately, and is used to increase the intake air pressure and air volume, while reducing airflow energy loss and operating noise.

[0068] The cover 225 is configured as a ring structure and covers at least a portion of the upper end of the blade 223, with a humidifying air inlet forming in its center. Specifically, the cover 225 includes a connecting portion 2252 and a curved portion 2251. The connecting portion 2252 is ring-shaped and covers the radially outer side of the blade 223, with its bottom surface abutting the trailing edge 2232 of the blade 223, thereby forming an integral connection between the cover 225 and the blade 223, enhancing the structural strength of the ring-shaped blade 223 assembly formed by the blades 223. The curved portion 2251 bends upward and inward from the inner edge of the connecting portion 2252, forming a transitional curved surface that guides the airflow in.

[0069] Thus, when the air deflector 240 is installed on the humidifier 220, the inner side of its air deflector and pressurization ring 242 accommodates the curved portion 2251 of the cover 225, forming a nested fit structure. This fit allows the external airflow to smoothly turn along the surface of the curved portion 2251 and concentrate into the humidifier air inlet under the guidance and pressurization of the air deflector and pressurization ring 242, effectively reducing eddies and inlet losses, thereby improving intake efficiency and overall aerodynamic performance.

[0070] Based on the humidifier section 220 structure of the first embodiment described above, when the humidifier device 200 is started, the humidifier section 220 rotates at high speed under the drive of the motor. At this time, the lower end (i.e., the small-diameter end) of the first water-absorbing section 221, which is submerged below the liquid surface of the water storage section 210, increases the liquid contact area through the water-absorbing ribs provided inside under the action of centrifugal force, thus pushing the liquid to rotate and rise. The liquid enters its interior through the opening at the bottom of the first water-absorbing section 221 and is continuously transported upward along the inner peripheral wall until it reaches the water distribution section 222.

[0071] Meanwhile, under the negative pressure created by the rotation of the humidifier 220, outside air enters through the air inlet above the deflector 240, and after being guided and pressurized by the flow-guiding and pressurizing ring 242, it enters the humidifier 220. The n-shaped structure of the flow-guiding and pressurizing ring 242 not only helps to increase the air outlet speed, but also effectively reduces airflow energy loss and operating noise.

[0072] After the liquid enters the water distribution section 222, it forms a uniform water film on the first inclined surface 2221 and rises upward as the rotation accelerates. When the liquid film comes into contact with the rotating blade 223, it will rise further along the surface of the blade 223 and fully mix with the air from the air inlet at high speed, forming a gas-liquid mixture that is then blown out from the humidification section 220.

[0073] Finally, the droplets ejected from the humidification section 220 collide with the water-breaking wall 241 on the inner wall of the water storage section 210, achieving secondary breakage through collision. The higher the initial ejection velocity of the droplets, the more significant the impact and breakage effect, thereby forming a finer water mist and improving the overall humidification efficiency and uniformity.

[0074] Second Embodiment

[0075] Figure 6 This is a perspective view of the humidifier section of a second illustrative embodiment of the present invention. Figure 7 for Figure 6 The diagram shows a half-section of the humidifier section.

[0076] According to an embodiment of the present invention, referring to Figure 6 and Figure 7 As shown, a bending plate 226 is provided at the lower end of the blade 223, forming a water distribution section 222, and the upper end surface of the bending plate 226 defines a first inclined surface 2221. The bending plate 226 extends from one blade 223 to another adjacent blade 223 along the rotation direction of the humidifying section 220, and bends upward.

[0077] In some illustrative embodiments, reference is made to Figure 7 As shown, the lower end of each blade 223 extends to form a bent plate 226. The bent plate 226 is arranged obliquely upward along the bending direction of the blade 223 and is located between two adjacent blades 223.

[0078] Taking the counterclockwise rotation of the drive unit 230 in the first embodiment as an example, the bending plate 226 extends from the lower end of a blade 223 in a counterclockwise direction to the adjacent blade 223, and is in an upward inclined posture. This structure makes the air outlet of the humidifier 220 form a sloping layout, thereby allowing the liquid to fly out from different heights, effectively improving the spatial dispersion of the liquid.

[0079] Compared to the integrally formed umbrella-shaped water distribution section 222 in the first embodiment, the water distribution function in this embodiment is achieved by the combined bending plates 226 of each blade 223. The space enclosed by the upper part of the blade 223, the bending plates 226, and the adjacent blades 223 together constitutes a composite channel through which the gas-liquid mixture flows.

[0080] Based on this, the other features of the second embodiment have been described in the first embodiment above, and will not be repeated here.

[0081] Third Embodiment

[0082] Figure 8 This is a perspective view of the humidifier section of the third embodiment of the present invention. Figure 9 for Figure 8 The diagram shows a half-section of the humidifier section.

[0083] According to an embodiment of the present invention, referring to Figure 8 and Figure 9 As shown, the humidification unit 220 also includes a toothed portion 270, which is disposed on the outer edge of the water distribution unit 222. The toothed portion 270 has multiple teeth arranged in the circumference of the water distribution unit 222, and each tooth of the toothed portion 270 protrudes in a direction away from the water storage unit 210.

[0084] According to an embodiment of the present invention, referring to Figure 8 and Figure 9 As shown, the teeth of the protruding tooth portion 270 have at least one inclined edge 271, which is inclined upward from the water distribution portion 222 along the rotation direction of the first water absorption portion 221.

[0085] According to an embodiment of the present invention, referring to Figure 8 and Figure 9 As shown, the humidifying unit 220 also includes a partition 250. The partition 250 is disposed above the water distribution unit 222 to divide the humidifying unit 220 into an upper space located above the partition 250 and a lower space located between the partition 250 and the water distribution unit 222. The partition 250 is provided with a first through hole 251 extending along the thickness direction, and the upper space and the lower space are connected through the first through hole 251.

[0086] According to an embodiment of the present invention, referring to Figure 8 and Figure 9 As shown, the partition 250 defines a second inclined surface 253, which is parallel to the first inclined surface 2221.

[0087] According to an embodiment of the present invention, referring to Figure 8 and Figure 9 As shown, a second through hole 252 is formed in the middle of the partition 250, and a second water-absorbing part 260 is formed on the inner edge of the second through hole 252. The second water-absorbing part 260 is connected to the first water-absorbing part 221.

[0088] According to an embodiment of the present invention, referring to Figure 8 and Figure 9 As shown, the second water-absorbing part 260 extends downward and is connected to the first water-absorbing part 221.

The second through hole 252 and the third through hole 261 are connected to the lower space.

[0089] In some illustrative embodiments, reference is made to Figure 8 and Figure 9As shown, the humidifying unit 220 also includes a partition 250 disposed below the annular blades 223. This partition 250 may include, but is not limited to, being configured as an umbrella-shaped structure, extending in the same direction as the water distribution unit 222, with its upper surface defining a second inclined surface 253, which is configured parallel to the first inclined surface 2221 of the water distribution unit 222. An upper space is formed between the partition 250 and the cover 225, and a lower space is formed between the partition 250 and the water distribution unit 222. In some preferred embodiments, the partition 250 is positioned at approximately one-fifth of the vertical height of the blades 223. That is, the lower one-fifth of the blades 223 is located in the lower space, while the upper four-fifths of the blades 223 are located in the upper space, thus making the height of the upper space approximately four times that of the lower space. It should be understood that the embodiments of this invention are not limited to this.

[0090] For example, the ratio between the upper space and the lower space can be 1:1, 2:1, 3:1, 4:1, or any other ratio.

[0091] Furthermore, the partition 250 has a second through hole 252 in the middle, and its inner edge forms a funnel-shaped second water-absorbing part 260. This structure is connected to and maintains communication with the large-diameter end of the first water-absorbing part 221. In addition, a second through hole 252 and a third through hole 261 communicating with the lower space are provided at the connection between the two. At the same time, the bottom wall of the partition 250 also has a first through hole 251 communicating with the upper and lower spaces.

[0092] Based on the above structure, after the liquid stored in the water storage section 210 is drawn in from the first water absorption section 221, a portion of it enters the lower space through the second through hole 252 and the third through hole 261, forming a uniform water film on the first inclined surface 2221 of the water distribution section 222 and accelerating upward. It then contacts the blade 223 (i.e., the lower fifth) and rises along the blade 223, mixing with the air entering from the humidification air inlet and then being introduced into the lower space through the first through hole 251 before being blown out. The other portion of the liquid continues to rise to the second water absorption section 260, forming a water film on the second inclined surface 253 of the partition 250 and accelerating, mixing with the air directly entering the upper space before being blown out. This achieves a double-layer water and air outlet, effectively increasing the contact area between the gas and liquid and improving humidification efficiency.

[0093] Furthermore, this embodiment also provides a protruding toothed portion 270 protruding towards the cover portion 225 on the outer edge of the water distribution portion 222. The protruding toothed portion 270 has multiple teeth along the circumference. Each tooth shape includes at least one hypotenuse 271: for example, in a tooth configured as a right-angled triangle, the side other than the right-angled side can be used as the hypotenuse 271; in a non-right-angled triangle tooth such as an isosceles triangle, any one side can be used as the hypotenuse 271. Thus, when the liquid flows through the protruding toothed portion 270, it can climb along the hypotenuse 271 and then fly outward at a higher speed along the rotation direction.

[0094] This implementation not only improves the uniformity of liquid distribution but also reduces the motor load by imparting higher initial kinetic energy to the liquid, thereby achieving the goal of configuring a smaller motor and saving energy and protecting the environment.
