[0105] like Figure 1 and Figure 2 As shown, this embodiment provides a water-washing air device 10 , comprising: a base 100 , a water curtain forming device 200 , a water tank 300 and an air driving device 400 .

[0106] Among them, the water curtain forming device 200 is arranged in the water tank 300, and the water curtain forming device 200 is used to absorb water in the water tank 300 to form a water curtain; an air inlet 301 is provided on the water tank 300, and an air outlet 401 is provided on the air driving device 400. The air driving device 400 is arranged above the water tank 300 and is connected to the water tank 300. The air driving device 400 drives the air to enter the water tank 300 from the air inlet 301 and be discharged from the air outlet 401.

[0107] Specifically, in this embodiment, the water tank 300 is disposed on the base 100 , the air driving device 400 is disposed above the water tank 300 and communicates with the water tank 300 , and the water curtain forming device 200 is disposed in the water tank 300 .

[0108] The water tank 300 is used to hold water for use by the water curtain forming device 200 ; the exemplary water tank 300 may be in a regular shape such as a cylinder or a cuboid. Of course, the water tank 300 may also be in other irregular shapes, which is not limited in this embodiment.

[0109] The water tank 300 includes a bottom surface, a top surface facing away from the bottom surface, and a side wall located between the bottom surface and the top surface; an air inlet 301 is provided on the water tank 300, and the air inlet 301 can be set on the side wall of the water tank 300. In order to prevent the water in the water tank 300 from flowing out through the air inlet 301, the air inlet 301 can be set on the side wall of the water tank 300 near the top; a through hole connected to the air drive device 400 is provided on the top surface of the water tank 300. After the air enters the water tank 300 through the air inlet 301, it contacts the water curtain formed by the water curtain forming device 200 to achieve air cleaning. After that, the air flows upward into the air drive device 400 and flows out from the air outlet 401 on the air drive device 400.

[0110] In this embodiment, the air driving device 400 can be a device capable of conveying air, such as a fan or an air pump. When the air driving device 400 is a fan, the corresponding fan can be a centrifugal fan, an axial flow fan or a diagonal flow fan.

[0111] For example, when the air drive device 400 is a centrifugal fan, the through hole on the top surface of the water tank 300 can be set directly opposite the center line of the centrifugal fan blade, and the air outlet 401 is set in the tangential direction of the rotation of the centrifugal fan blade. The centrifugal fan draws air from the air inlet 301 and then discharges the air to the outside through the air outlet 401; illustratively, there can be two air outlets 401, and the two air outlets 401 are set opposite to each other to increase the air output.

[0112] In this embodiment, the water curtain forming device 200 is disposed within the water tank 300. It draws water from the water tank 300 and lifts it to form a water curtain within the water tank 300. The water curtain forms between the air inlet 301 and the through-hole, allowing air to come into contact with the water curtain as it circulates within the water tank 300, thereby cleaning the air and improving air quality. When the air comes into contact with the water curtain, impurities such as dust, hair, lint, and microorganisms in the air are absorbed by the water curtain and filtered out. Furthermore, the air carries some moisture with it, increasing the humidity and enhancing the user experience.

[0113] As can be seen from the above description, the water-washing air device provided in this embodiment allows air to enter the water tank 300 through the air inlet 301. Driven by the air drive device 400, the air passes through the water curtain and is then discharged to the external environment. The water curtain cleans the air, thereby purifying it. The water-washing solution not only removes dust and microorganisms entrained in the air but also solves the problem of dry indoor air, thereby effectively improving indoor air quality and enhancing the user experience.

[0114] In this embodiment, the water tank 300 is detachably mounted on the base 100, making it easy to add water to the water tank 300 or remove wastewater from the water tank 300. A certain amount of displacement space is provided between the water tank 300 and the upper air drive device 400, facilitating removal of the water tank 300 or installation on the base 100. In other words, to remove the water tank 300 in this embodiment, it is necessary to first lift the water tank 300 vertically a certain distance and then pull it out horizontally.

[0115] like Figure 3 As shown, the water tank 300 of this embodiment is provided with a scale line 351 for displaying the height of the water level in the water tank 300 , so that the user can observe the height of the liquid level in the water tank 300 in real time.

[0116] In order to improve the visualization effect of the water tank 300 and facilitate the observation of the liquid level in the water tank 300 or the water curtain sprayed by the water curtain forming device 200, the water tank 300 as a whole can be a transparent box body, or the water tank 300 includes a transparent side wall 350, and the scale line 351 is set on the transparent side wall 350.

[0117] The scale lines 351 include a plurality of horizontal indicator lines arranged vertically on the water tank 300, and at least some of the horizontal indicator lines are provided with digital symbols for indicating the volume of water in the water tank 300. The digital symbols may indicate the volume of water in the water tank 300 at the current height, or the digital symbols may indicate the liquid level in the water tank 300 at the current height.

[0118] The digital identification may further include a water level peak prompt to remind the user not to continue filling water into the water tank 300 .

[0119] A water level sensor can also be provided in the water tank 300. The water level sensor can be set in the water tank 300 at the lowest liquid level required to maintain the normal operation of the water washing air device 10. The water level sensor is communicated with an external alarm device for sending a water shortage prompt to the user, so as to send a water shortage prompt to the user through the alarm device.

[0120] The following describes the structure of the water tank 300 in this embodiment. Figure 4-Figure 7In the water tank 300 of this embodiment, a water retaining structure 360 is provided on the side of the air inlet 301 facing the inside of the water tank 300. The water retaining structure 360 can block the water droplets thrown toward the air inlet 301 by the water curtain forming device 200, thereby preventing water from being thrown out of the air inlet and improving the user experience.

[0121] When this embodiment is in use, the water thrown toward the side wall of the water tank by the water curtain forming device 200 will flow downward along the side wall of the water tank. To further prevent this water from flowing out of the air inlet, a water collecting trough 370 and a plurality of water guide grooves 380 are provided on the side wall of the water tank 300. The water collecting trough 370 is located above the air inlet 301, and the plurality of water guide grooves 380 are all connected to the water collecting trough 370. The water guide grooves 380 are used to guide the water in the water collecting trough 370 to the lower end of the water tank 300. The water collecting trough 370 can collect the water droplets thrown out by the water curtain forming device 200. Through the guidance of the water guide grooves 380, the water flow can flow directly from the water collecting trough 370 to the lower end of the water tank 300 without passing through the air inlet 301, thereby avoiding the risk of water flowing out of the air inlet 301.

[0122] Optionally, the water retaining structure 360 of this embodiment is detachably disposed in the water tank 300 , thereby facilitating installation and disassembly.

[0123] Specifically, a fixing groove 390 is provided above the water collecting groove 370, and a fixing protrusion 3613 adapted to the fixing groove 390 is provided on the water retaining structure 360. The fixing protrusion 3613 overlaps in the fixing groove 390, thereby realizing a detachable connection between the water retaining structure 360 and the water tank 300.

[0124] The water retaining structure 360 further includes a water retaining bracket 361 and a water retaining member 362 arranged on the water retaining bracket 361. The water retaining bracket 361 includes a top wall 3611 and a plurality of supporting arms 3612 connected to the top wall 3611. The water retaining member 362 is arranged on the supporting arms 3612, and the fixing protrusion 3613 is arranged on the top wall 3611.

[0125] In an optional embodiment, the water retaining member 362 may include a water retaining sponge, the lower end of which is immersed in the water in the water tank 300, thereby humidifying the incoming air while retaining water and increasing the water content of the purified air.

[0126] In another optional embodiment, the water retaining member 362 includes a plurality of water retaining fins, which are arranged obliquely relative to the air inlet 301. When placed perpendicular to the air inlet 301, two adjacent water retaining fins partially overlap, thereby better preventing water droplets from flowing out of the air inlet 301. With this solution, water droplets hitting the water retaining fins will produce a certain amount of negative ions, further improving the purification effect. In addition, the wind resistance of the water retaining fins is higher than that of the humidification net, which helps to increase the air intake.

[0127] The water tank 300 of this embodiment includes a curved side wall 302 , and the air inlet 301 , the water collecting groove 370 and the fixing groove 390 are all provided on the curved side wall 302 .

[0128] In this embodiment, a plurality of air inlets 301 may be provided on the arc-shaped side wall 302 , and the water guide groove 380 is provided between two adjacent air inlets 301 , so as to guide the water in the water collecting groove 370 more evenly.

[0129] In order to further improve the purification effect, a filter 303 is provided on the side of the air inlet 301 of this embodiment that is away from the interior of the water tank 300, thereby filtering the air entering the water tank and improving the purification quality.

[0130] A water retaining net 304 may also be provided between the air driving device 400 and the water tank 300 to prevent moisture from entering the air driving device 400 and causing damage thereto, thereby extending the service life of the air driving device 400.

[0131] The following describes the connection relationship between the water tank 300 and the base 100 in this embodiment. Figure 8-Figure 9 Since the water tank 300 in this embodiment is detachably connected to the base 100, to ensure precise installation between the water tank 300 and the base 100 and prevent relative movement between the water tank 300 and the base 100 during use, a first positioning portion 310 extending in a first direction is provided on the bottom surface of the water tank 300, and a first matching portion 110 extending in the first direction is provided on the top surface of the base 100. The first positioning portion 310 and the first matching portion 110 cooperate to limit movement of the water tank 300 relative to the base 100 in a second direction. The first direction and the second direction are two intersecting directions on the bottom surface of the water tank 300. During use, the second direction can be the direction in which the water tank 300 is withdrawn. In this embodiment, the angle between the first direction and the second direction can be set as needed. For example, in a preferred embodiment, the angle between the first direction and the second direction can be 90°. In other optional embodiments, the angle between the first direction and the second direction can also be 60°, 75°, 80°, etc. Through the above-mentioned arrangement, the precise fit between the water tank 300 and the base 100 can be ensured, so that the components in the water curtain forming device 200 can be precisely assembled to ensure the normal operation of the water washing air device 10; at the same time, the matching connection relationship between the first positioning portion 310 and the first matching portion 110 can also prevent the water tank 300 from moving relative to the base 100 during operation.

[0132] In actual cooperation, the base 100 may be provided with a mounting groove 101, and the bottom surface of the water tank 300 is clamped in the mounting groove 101. The specific clamping cooperation mode between the water tank 300 and the base 100 can be selected according to needs, and this embodiment does not further limit this.

[0133] Specifically, the first positioning portion 310 can be a first groove provided at one end of the bottom surface of the water tank 300. The first groove includes a bottom wall 311 and a first side wall 312, with the first side wall 312 being inclined relative to the bottom wall 311. The first mating portion 110 can be a first protrusion provided at one end of the mounting groove 101. The first protrusion includes a top wall 111 and a second side wall 112, with the second side wall 112 being inclined relative to the top wall 111. To remove the water tank 300 from the base 100, the water tank 300 must first be lifted upward along the first protrusion to a certain height, then slightly tilted at a certain angle and removed along the second direction.

[0134] Furthermore, a plurality of second positioning portions 320 are provided on the bottom surface of the water tank 300, and a plurality of second matching portions 120 are provided in the mounting groove 101. The plurality of second positioning portions 320 cooperate with the plurality of second matching portions 120 one by one to further limit the relative movement between the base 100 and the water tank 300.

[0135] In an alternative embodiment, the second positioning portion 320 comprises a recessed portion disposed on the bottom surface of the water tank 300, and the second mating portion 120 comprises a protruding portion disposed within the mounting groove 101. The protruding portion is conical in shape, with a cross-sectional area gradually decreasing in a direction away from the mounting groove 101; the corresponding recessed portion is also conical in shape, and its outer shape matches that of the protruding portion.

[0136] To facilitate the user in removing and installing the water tank 300, a pick-up and placement portion 330 is provided on the two opposite side walls of the water tank 300 along the first direction. The pick-up and placement portion 330 is a groove or protrusion arranged on the side wall of the water tank 300. The user can grab the pick-up and placement portion 330 to apply force to the water tank 300 when installing or removing the water tank 300.

[0137] Please continue to refer to Figures 10-18 The water curtain forming device 200 of this embodiment includes a driving member 210 and a water-spinning member 220. The driving member 210 is arranged on the base 100, and the water-spinning member 220 is arranged in the water tank 300; the output shaft 211 of the driving member 210 is connected to the driving shaft 221 of the water-spinning member 220.

[0138] Specifically, the output shaft 211 of the driving member 210 is fitted with a first conical rotating disk 212. A plurality of first driving blocks 2120 are disposed on the surface of the first rotating disk 212 facing the water tank 300. The lower end of the driving shaft 221 of the water-spinning member 220 extends outside the water tank 300 and is fitted with a second conical rotating disk 222. A plurality of first driving slots 2220 are disposed on the surface of the second rotating disk 222 facing the base 100. Each first driving block 2120 is engaged with a corresponding first driving slot 2220.

[0139] In this embodiment, the base 100 is provided with a mounting portion for mounting the driver 210. The mounting portion is located on the side of the base 100 facing away from the water tank 200. The base of the driver 210 is provided with a plurality of connecting legs 213, each of which may be provided with fixing holes for securing it to the base 100. The base 100 is provided with a through hole 130, through which the output shaft of the driver 210 passes before connecting to the drive shaft 221. The upper end of the output shaft 211 is provided with an external thread, and a threaded hole with an internal thread may be provided at the center of the first rotating disk 212. The first rotating disk 212 can be connected to the output shaft 211 via a threaded connection.

[0140] The bottom surface of the water tank 300 is further provided with a second rotating disk mounting groove 340 for accommodating the second rotating disk 222. The second rotating disk 222 is disposed within the second rotating disk mounting groove 340. Specifically, the lower end of the drive shaft 221 extends outside the water tank 300 and is located within the second rotating disk mounting groove 340. The lower end of the drive shaft 221 may be provided with an external thread, and the center of the second rotating disk 222 may be provided with an internal threaded hole. The lower end of the drive shaft 221 and the second rotating disk 222 may be connected and fixed by a threaded connection.

[0141] The first rotating disk 212 and the second rotating disk 222 can be meshed and driven by the first driving block 2120 and the first driving slot 2220. Since both the first rotating disk 212 and the second rotating disk 222 are conical in shape, they can form a horizontal limit for the water tank 300 when they cooperate, preventing the water tank 300 from separating from the base 100 and ensuring that the water tank 300 cannot be directly withdrawn horizontally.

[0142] The second rotating disk installation groove 340 may be located between the two second positioning portions 320 , and the assembly accuracy of the first rotating disk 212 and the second rotating disk 222 may be ensured by the two second positioning portions 320 .

[0143] Furthermore, in order to reduce the vibration and noise during the transmission of the water curtain forming device 200, reduce the friction between the first rotating disk 212 and the second rotating disk 222, and improve the service life of the two, this embodiment is provided with a rubber sleeve on the surface of the first rotating disk 212 facing the water tank 300, and the shape of the rubber sleeve can be adapted to the surface of the first rotating disk 212 facing the water tank 300.

[0144] From the above description, it can be seen that the driving structure in the water curtain forming device 200 of this embodiment includes a driving member 210 arranged on the chassis 100, and the output shaft 211 of the driving member 210 is connected to the first rotating disk 212 after passing through the through hole 130 on the chassis 100, and drives the first rotating disk 212 to rotate; the water-spinning member 220 is arranged in the water tank 300, and the lower end of the driving shaft 221 of the water-spinning member 220 extends out of the water tank 300 and is connected to the second rotating disk 222. Through the meshing transmission between the first rotating disk 212 and the second rotating disk 222, the driving member 210 drives the water-spinning member 220 to rotate, thereby forming a water curtain in the water tank 300.

[0145] Furthermore, the water-repelling component 220 of this embodiment includes a cylinder 223 and an end cover 224. The end cover 224 is covered on the upper end of the cylinder 223. The lower end of the cylinder 223 is provided with an opening. A gap is formed between the opening and the bottom surface of the water tank 300. A plurality of spray holes 22311 are provided on the side wall of the cylinder 223. A fixing portion 2233 is provided in the cylinder 223. The fixing portion 2233 is sleeved on the outside of the drive shaft 221 to prevent the drive shaft 221 from shaking.

[0146] With the above arrangement, when the driving member 210 drives the water-spinning member 220 to rotate at high speed, a negative pressure is generated inside the water-spinning member 220. Due to the pressure difference, water stored in the water tank 300 can enter the water-spinning member 220, that is, the water in the water tank 300 is drawn into the water-spinning member 220. Driven by the rotation of the water-spinning member 220, the water is ejected through the ejection holes 22311. The ejected water forms water droplets that are dispersed within the water tank 300, thereby forming a multi-layer water curtain.

[0147] The fixing portion 2233 and the cylindrical body 223 may be connected via a plurality of connecting ribs 2234 . The plurality of connecting ribs 2234 may be evenly arranged on the outer side of the fixing portion 2233 along the circumference of the fixing portion 2233 .

[0148] At least one positioning surface 2211 is provided on the side surface of the drive shaft 221, and a mating surface 22331 adapted to the positioning surface 2211 is provided in the fixing portion 2233. Through the mating transmission between the positioning surface 2211 and the mating surface 22331, slipping between the drive shaft 221 and the fixing portion 2233 can be prevented, which is conducive to the drive shaft 221 transmitting the driving force to the water-spraying component 220.

[0149] Furthermore, a shaft sleeve may be provided between the driving shaft 221 and the fixing portion 2233 to further improve the transmission stability between the two.

[0150] In this embodiment, the upper end of the drive shaft 221 is fixedly connected to the end cap 224 to further enhance the stability of the connection between the drive shaft 221 and the water-splitting member 220. Specifically, the end cap 224 is provided with a connecting portion 2241 having a connecting hole with an internal thread. The upper end of the drive shaft 221 is provided with an external thread, and the drive shaft 221 and the end cap 224 are connected and fixed by a threaded connection.

[0151] The barrel 223 of this embodiment may include a first section 2231 and a second section 2232 connected in sequence. The first section 2231 is fixedly connected to the end cap 224, and the second section 2232 has an opening. The first section 2231 may be located on top of the second section 2232. Optionally, the two may be integrally formed.

[0152] A plurality of spray holes 22311 are provided on the first section 2231. Since water will climb along the inner wall of the cylinder 223 under the action of centrifugal force, the spray holes 22311 are provided in the first section 2231, which can increase the water outlet height, so that the water curtain can rely on gravity to fill the entire water tank, increase the contact area with the air, and improve the cleaning effect.

[0153] Multiple spray holes 22311 can be arranged into multiple rows on the first end 2231 in the vertical direction, and the spray holes 22311 in each row can be evenly distributed in the circumferential direction, so that a multi-layer water curtain structure can be formed in the water tank 300 to improve the washing efficiency of the air.

[0154] The inner surface of the second section 2232 is provided with a plurality of guide ribs 22321, which are spaced apart along the circumference of the second section 2232, and each guide rib 22321 extends from the opening toward the first section 2231. The guide ribs 22321 can guide the water flow to the first end 2231 more quickly, thereby improving the water rejection efficiency.

[0155] The first section 2231 can be a cylindrical or conical structure, and the second section 2232 can be a conical structure. The cross-sectional area of the second section 2232 decreases from one end close to the first section 2231 to the opening, so that water can more easily climb along the inner surface of the second section 2232 and quickly reach the injection hole 22311, thereby increasing the speed of forming the water curtain.

[0156] The outer surface of the first section 2231 is further provided with a plurality of blades 22312, which are spaced apart along the circumference of the first section 2231. The blades 22312 can draw air closer during the rotation of the water-spinning member 220, allowing the air entering the water tank 300 from the air inlet 301 to pass through more water curtains, thereby achieving a better cleaning effect.
