Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0081] Secondly, it should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0082] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0083] With the gradual development of air treatment equipment technology, equipment for purifying, humidifying, etc. the air is gradually applied to air conditioners or fresh air fans to improve the user experience.

[0084] In the related art, an air washing device is used to process air to improve air quality. The air washing device includes a housing, a water tank, a fan, and a water curtain forming device. The water tank is arranged on the housing. An air inlet is arranged on the side wall of the water tank, and an air outlet is arranged at the top of the water tank. The fan is connected to the water tank to drive air to enter the water tank from the air inlet, and the air in the water tank flows out from the air outlet. The water curtain forming device is arranged in the water tank. The water curtain forming device can suck the water in the water tank and release it in the form of a water curtain in the water tank to form a water curtain in the water tank. During use, air enters from the air inlet and flows out from the air outlet. When the air flows in the water tank, it will pass through the water curtain formed by the water curtain forming device, thereby realizing the cleaning of the air and improving air quality.

[0085] For the above-mentioned air washing device, after using it for a period of time, it is necessary to add water to the water tank to supplement the consumed water.

[0090] like Figure 1 and Figure 2 As shown, this embodiment provides a water-washing air device 10 , including: a base 100 , a water curtain forming device 200 , a water tank 300 and an air driving device 400 .

[0091] 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 arranged on the water tank 300, and an air outlet 401 is arranged on the air driving device 400. The air driving device 400 is arranged above the water tank 300 and is connected with 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.

[0092] 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 communicated with the water tank 300 , and the water curtain forming device 200 is disposed in the water tank 300 .

[0093] 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, and of course the water tank 300 may also be in other irregular shapes, which is not limited in this embodiment.

[0094] 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 driving 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. Then the air flows upward into the air driving device 400 and flows out from the air outlet 401 on the air driving device 400.

[0095] In this embodiment, the air driving device 400 may 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 may be a centrifugal fan, an axial flow fan or a diagonal flow fan.

[0096] For example, when the air driving device 400 is a centrifugal fan, the through hole on the top surface of the water tank 300 can be arranged facing the center line of the fan blades of the centrifugal fan, and the air outlet 401 is arranged in the tangential direction of the centrifugal fan along the rotation of the fan blades. The centrifugal fan extracts air from the air inlet 301 and then discharges the air to the outside through the air outlet 401. Exemplarily, there can be two air outlets 401, and the two air outlets 401 are arranged oppositely, which can increase the air output volume.

[0097] In this embodiment, the water curtain forming device 200 is arranged in the water tank 300. The water curtain forming device 200 can suck the water in the water tank 300, lift the water and form a water curtain in the water tank 300. The water curtain is formed between the air inlet 301 and the through hole, so that when the air flows in the water tank 300, it contacts the water curtain, thereby realizing the cleaning of the air and improving the air quality. When the air contacts the water curtain, impurities such as dust, hair, lint and microorganisms in the air will be adsorbed by the water curtain and then filtered out. In addition, the air will carry some moisture and flow out, which can increase the humidity of the air to improve the user experience.

[0098] From the above description, it can be seen that using the air washing device provided in this embodiment can make the air enter the water tank 300 from the air inlet 301, and under the drive of the air driving device 400, the air passes through the water curtain and is then exported to the external environment, so as to clean the air with the water curtain and purify the air. The water washing scheme can not only remove the dust and microorganisms entrained in the air, but also solve the problem of dry indoor air, thereby effectively improving the indoor air quality and enhancing the user experience.

[0099] In this embodiment, the water tank 300 is detachably arranged on the base 100 to facilitate adding water to the water tank 300 or cleaning the sewage in the water tank 300. There is a certain displacement space between the water tank 300 and the upper air driving device 400 to facilitate taking out or installing the water tank 300 on the base 100. That is, when taking out the water tank 300 in this embodiment, it is necessary to first lift the water tank 300 upward by a certain distance in the vertical direction and then draw it out in the horizontal direction.

[0100] As Figure 3 shown, a scale line 351 for displaying the water surface height in the water tank 300 is provided on the water tank 300 of this embodiment to facilitate the user to observe the liquid level height in the water tank 300 in real time.

[0101] To improve the visualization effect of the water tank 300 and facilitate observing the liquid level in the water tank 300 or the water curtain ejected by the water curtain forming device 200, the water tank 300 can be an overall transparent box, or the water tank 300 includes a transparent side wall 350, and the scale line 351 is arranged on the transparent side wall 350.

[0102] The scale line 351 includes a plurality of indicating horizontal lines arranged vertically on the water tank 300, and digital identifications for displaying the volume of water in the water tank 300 are provided beside at least some of the indicating horizontal lines. Among them, the digital identifications can identify the volume of water in the water tank 300 at the current height, or the digital identifications can identify the liquid level height in the water tank 300 at the current height.

[0103] The digital identifications can also include a prompt for the highest water level to remind the user not to continue filling water into the water tank 300.

[0104] A water level sensor can also be provided in the water tank 300. The water level sensor can be arranged at the lowest liquid level necessary for maintaining the normal operation of the water washing air device 10 in the water tank 300. The water level sensor is communicatively connected to 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.

The lower end of the driving shaft 221 may be provided with an external thread, and the center of the second rotating disk 222 may be provided with an internal thread hole. The lower end of the driving shaft 221 and the second rotating disk 222 may be connected and fixed by a threaded connection.

[0115] The first rotating disk 212 and the second rotating disk 222 can be meshed and driven by the cooperation of the first driving block 2120 and the first driving groove 2220. Since the first rotating disk 212 and the second rotating disk 222 are both conical, they can form a limit for the water tank 300 in the horizontal plane after the cooperation, preventing the water tank 300 from separating from the base 100, and ensuring that the water tank 300 cannot be directly drawn out horizontally.

[0116] 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 .

[0117] 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 increase 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.

[0118] As can be seen from the above description, the drive structure in the water curtain forming device 200 of this embodiment includes a driving member 210 disposed on the chassis 100. The output shaft 211 of the driving member 210 passes through the through hole 130 on the chassis 100 and is connected to the first rotating disk 212, driving the first rotating disk 212 to rotate. The water throwing member 220 is disposed in the water tank 300. The lower end of the driving shaft 221 of the water throwing 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 throwing member 220 to rotate, thereby forming a water curtain in the water tank 300.

[0119] Furthermore, the water throwing member 220 of this embodiment includes a cylinder body 223 and an end cover 224. The end cover 224 covers the upper end of the cylinder body 223. An opening is provided at the lower end of the cylinder body 223, and a gap is formed between the opening and the bottom surface of the water tank 300. A plurality of spraying holes 22311 are provided on the side wall of the cylinder body 223. A fixing portion 2233 is provided inside the cylinder body 223. The fixing portion 2233 is sleeved outside the driving shaft 221 to prevent the driving shaft 221 from shaking.

[0120] With the above settings, when the driving member 210 drives the water throwing member 220 to rotate at a high speed, a negative pressure can be formed inside the water throwing member 220. Under the action of the pressure difference, the water stored in the water tank 300 can enter the water throwing member 220, that is, the water in the water tank 300 is sucked into the water throwing member 220, and under the drive of the rotation of the water throwing member 220, it is ejected through the spraying holes 22311. The ejected water can form water droplets scattered in the water tank 300, thereby forming multiple layers of water curtains.

[0121] The fixing portion 2233 and the cylinder body 223 can be connected by a plurality of connecting ribs 2234. The plurality of connecting ribs 2234 can be uniformly arranged on the outside of the fixing portion 2233 along the circumferential direction of the fixing portion 2233.

[0122] At least one positioning surface 2211 is provided on the side surface of the driving shaft 221. A mating surface 22331 adapted to the positioning surface 2211 is provided inside the fixing portion 2233. Through the mating transmission between the positioning surface 2211 and the mating surface 22331, the slipping phenomenon between the driving shaft 221 and the fixing portion 2233 can be prevented, which is beneficial for the driving shaft 221 to transmit the driving force to the water throwing member 220.

[0123] Furthermore, a bushing can be provided between the driving shaft 221 and the fixing portion 2233 to further improve the transmission stability between the two.

[0124] In this embodiment, the upper end of the drive shaft 221 is fixedly connected to the end cover 224 to further improve the stability of the connection and cooperation between the drive shaft 221 and the water throwing member 220. Specifically, a connection portion 2241 is provided on the end cover 224, and a connection hole with an internal thread is formed on the connection portion 2241. The upper end of the drive shaft 221 is provided with an external thread, and the drive shaft 221 and the end cover 224 are connected and fixed by means of threaded connection.

[0125] The cylinder body 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 cover 224, and the second section 2232 has an opening. The first section 2231 may be located at the top of the second section 2232. Optionally, the two may be integrally formed.

[0126] A plurality of spray holes 22311 are provided on the first section 2231. Since water will climb along the inner wall of the cylinder body 223 under the action of centrifugal force, setting the spray holes 22311 on the first section 2231 can increase the water outlet height, so that the water curtain can fill the entire water tank by gravity, increasing the contact area with air and achieving good cleaning effect.

[0127] The plurality of spray holes 22311 may be arranged in multiple rows on the first section 2231 in the vertical direction, and the spray holes 22311 in each row may be evenly distributed in the circumferential direction, so as to form a multi-layer water curtain structure in the water tank 300 and improve the washing efficiency of air.

[0128] A plurality of guide ribs 22321 are provided on the inner surface of the second section 2232. The plurality of guide ribs 22321 are arranged at intervals in the circumferential direction of the second section 2232, and each guide rib 22321 extends from the opening towards the direction close to the first section 2231. The guide ribs 22321 can guide the water flow to rise to the first section 2231 faster, thereby improving the water throwing efficiency.

[0129] The first section 2231 may be a cylindrical barrel or a conical barrel-shaped structure, and the second section 2232 may be a conical barrel-shaped. The cross-sectional area of the second section 2232 decreases from the end close to the first section 2231 to the opening, and the water is more likely to climb along the inner surface of the second section 2232 and quickly reach the spray holes 22311, improving the formation speed of the water curtain.

[0130] A plurality of blades 22312 are further provided on the outer surface of the first section 2231. The plurality of blades 22312 are arranged at intervals in the circumferential direction of the first section 2231. The blades 22312 can draw in air during the rotation of the water throwing member 220, so that the air entering the water tank 300 from the air inlet 301 can pass through more water curtains, achieving better cleaning effect.
