[0003] As people become increasingly health-conscious, they are paying more and more attention to air quality in their indoor environments, beyond basic cooling and heating needs. To improve air quality, the common practice is to install filters in air circulation systems to remove airborne particles. However, harmful gas molecules in the air are difficult to remove, and cleaning or replacing filters can easily cause secondary pollution. Therefore, people have begun to try using circulating water for "water-washing purification" of the air.

[0004] In related technologies, a water-washing air purification device is disclosed, including a water tank, a water curtain assembly, and a water-blocking component. The water curtain assembly forms a water curtain within the water tank, purifying the air passing through it. The water-blocking component covers the air inlet of the water tank and includes water-blocking ribs to prevent at least some water droplets from splashing out of the water tank from the air inlet. By covering the air inlet of the water tank with the water-blocking component, at least some water droplets from the water tank are prevented from splashing out of the water tank, thereby reducing water leakage in the water-washing air purification device.

[0005] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0006] The water-blocking components in related technologies cannot completely prevent water droplets from splashing out of the water tank from the air inlet. Water-washable air purifiers may experience water overflow from the water tank after prolonged use. Summary of the Invention

[0047] Combination Figure 1-14 As shown in the figure, this disclosure provides a water-washable air purifier.

[0048] The water-washing air purifier provided in this embodiment includes a water tank 200, a water curtain generating unit 210, and a water-blocking mechanism 220. The water tank 200 has an air inlet on its side wall and an air outlet on its top. The water curtain generating unit 210 is rotatably disposed inside the water tank 200 and includes a water-spraying assembly and a driving device. The water-spraying assembly has multiple spray holes on its upper part. The driving device drives the water-spraying assembly to rotate at high speed, causing the water inside the assembly to become a vortex rotating around its interior, which is then sprayed out from the multiple spray holes to form a water curtain. The water-blocking mechanism 220 includes a first water-blocking plate 222, which is located between the spray holes and the air inlet of the water tank 200 to prevent the water curtain from splashing out of the air inlet. This application provides a first water-blocking plate 222 between the spray holes and the air inlet of the water tank 200, which can prevent the water curtain from splashing out of the air inlet of the water tank 200 while ensuring the airflow.

[0049] The water-washing air purifier is used to purify the air. A water tank 200 stores water and forms an airflow channel. Specifically, the water tank 200 has an air inlet on its side wall and an air outlet on its top. Air enters the water tank 200 through the air inlet and exits through the air outlet. A water curtain generating unit 210 is located inside the water tank 200 and is used to generate a water curtain. The water curtain generating unit 210 includes a water-spraying assembly and a driving device. Multiple spray holes are provided on the upper part of the water-spraying assembly. The driving device drives the water-spraying assembly to rotate at high speed, generating pressure, which causes the water inside the assembly to become a vortex rotating around its interior. Under centrifugal force, the water is sprayed out from the multiple spray holes, forming a water curtain. This water curtain is located between the air inlet and outlet of the water tank 200, that is, within the airflow channel of the water tank 200. Air passing through the airflow channel and then through the water curtain adsorbs impurities such as lint, dust, and hair, while harmful gases like formaldehyde dissolve in the water, thus purifying the air. Simultaneously, the large surface area of ​​contact between the air and water increases humidity as some of the water evaporates.

[0050] The water-blocking mechanism 220 includes a first water-blocking plate 222, which is located between the spray hole and the air inlet of the water tank 200. On the one hand, the first water-blocking plate 222 and the side wall where the air inlet of the water tank 200 is located form an air inlet area, allowing airflow to enter the water tank 200 along the air inlet area; on the other hand, when the water curtain collides with the first water-blocking plate 222, the first water-blocking plate 222 acts as a shield for the air inlet of the water tank 200, preventing the water curtain from splashing out of the water tank 200 through the air inlet.

[0051] Optionally, the water-spraying assembly includes a water pump and a spray pipe, with a first end of the spray pipe located at the bottom of the water tank 200 and a second end extending to the top of the water tank 200. The water pump is used to provide spray pressure to the spray pipe.

[0052] The water pump sends the water accumulated at the bottom of the water tank 200 to the top of the water tank 200 through the spray pipe, and the water falls from the top of the water tank 200 to form a water curtain.

[0053] Optionally, the second end of the spray pipe is provided with an annular water outlet, which surrounds the air outlet of the water tank 200.

[0054] In this configuration, the water curtain formed by the annular outlet is cylindrical, with the air outlet of water tank 200 located inside the cylindrical space and the air inlet of water tank 200 located outside. When air flows from the air inlet to the air outlet of water tank 200, it inevitably passes through the water curtain and is thus purified. This design enhances the air purification effect of the water-washed air purifier.

[0055] Optionally, the second end of the spray pipe has multiple water outlets, which are spaced apart around the air outlet. The water sprayed from the multiple water outlets at the second end of the spray pipe forms a water curtain.

[0056] Optionally, the distance between adjacent water outlets in the multiple outlets is 1-3mm. With a smaller distance between adjacent outlets, the water streams sprayed from multiple outlets connect with each other under the action of liquid surface tension, forming a seamless water curtain. This configuration improves the air purification effect of the water-washing air purifier.

[0057] Optionally, the second end of the spray pipe rotates about the axis of the water tank 200 around the air outlet. The water sprayed from the spray pipe has a uniform horizontal motion along the tangent of the circular motion, and a uniformly accelerated vertical motion under gravity. The water outlet makes a circular motion, and the tangent of the outlet constantly changes, resulting in a spiral with a gradually increasing diameter from top to bottom. Water sprayed from multiple outlets can more easily connect with each other under surface tension, forming a seamless water curtain. Furthermore, the water has an initial horizontal velocity, and the diameter of the water curtain is larger than the diameter of the circle formed by the circular motion of the outlet. This design simplifies the structure of the water curtain generating unit 210, reduces its volume, improves the uniformity of the water curtain, and increases its range. Furthermore, it improves the air purification effect of the water-washing air purifier.

[0058] Optionally, the water pump includes a motor 311 and a centrifuge cylinder. The centrifuge cylinder is vertically positioned, with its first end at the bottom of the water tank 200 and its second end extending beyond the water level line of the water tank 200. The diameter of the centrifuge cylinder gradually increases from the first end to the second end. The motor 311 drives the centrifuge cylinder to rotate, and the water inside the centrifuge cylinder generates centrifugal force as it rotates. The centrifugal force along the inclined wall of the centrifuge cylinder can be decomposed into a pressure perpendicular to the wall and a force parallel to the wall and upward. The force parallel to the wall and upward overcomes the effect of gravity, causing the water inside the centrifuge cylinder to move upward from the first end to the second end. A water outlet is provided at the second end of the centrifuge cylinder, from which water is sprayed out, thus forming a water curtain. In this case, the centrifuge cylinder serves as the spray pipe of the water curtain generating unit 210, and the water pump includes a motor 311, which drives the spray pipe to rotate to pump and pressurize the water. The spray pipe guides the water upward and sprays it out through spray holes.

[0059] Optionally, the bottom of the water tank 200 protrudes upward to form an inner cylinder, and a through hole is provided at the top of the inner cylinder. The centrifuge cylinder is fitted into the inner cylinder. The motor 311 is located outside the water tank and below the water tank 200, and its output shaft passes upward through the through hole to drive the centrifuge cylinder.

[0060] With this design, the motor 311 does not come into contact with the water in the water tank 200, preventing water ingress and potential malfunctions, and improving the safety of the water-washing air purifier. Furthermore, the motor 311's location outside the water tank simplifies its wiring.

[0061] Optionally, the output shaft of motor 311 includes a main output shaft and a docking output shaft. The main output shaft is fixed to motor 311, and the top end of the docking output shaft is fixed to the centrifuge drum or inner drum, while the bottom end is connected to the gear of the main output shaft. With this configuration, when the water tank 200 needs to be removed, it is not necessary to remove motor 311, which facilitates the use of the water-washable air purifier.

[0062] Optionally, the water-blocking mechanism 220 further includes a second water-blocking plate 221, which is disposed at the air outlet of the water tank 200 to prevent water from splashing out of the air outlet of the water tank 200. In this way, when the water-spraying component rotates too fast, causing the water curtain to be too high, water can be prevented from splashing upward from the water tank onto other components, thus avoiding affecting the purification effect of the water-washing air purifier.

[0063] Optionally, the outer ring of the second baffle plate 221 is linearly connected to the side wall of the water tank 200 and extends upward beyond the air inlet of the water tank 200, while the inner ring forms an air outlet; the first baffle plate 222 extends downward from the inner edge of the second baffle plate 221 and extends beyond the air outlet; wherein, the water curtain formed by the water curtain generating unit 210 is sprayed onto the first baffle plate 222.

[0064] The first baffle plate 222 and the side wall where the air inlet of the water tank 200 is located form an air duct. The second baffle plate 221 blocks the top of the air duct, so that the air entering the water tank 200 from the air inlet moves from the bottom of the baffle structure to the air outlet of the water tank 200. The water sprayed from the water curtain generating unit 210 sprays onto the first baffle plate 222, forming a water curtain in two parts. The first part is the water level from the water curtain generating unit 210 to the first baffle plate 222, and the second part is the water curtain falling from the first baffle plate 222 to the bottom of the water tank 200. The air moves from the bottom of the baffle mechanism 220 to the air outlet of the water tank 200, first passing through the second part of the water curtain, entering the inner circle of the water curtain, and then passing through the first part of the water curtain, moving towards the air outlet. Air entering the water tank passes through the water curtain twice, allowing impurities such as fluff, dust, and hair, as well as harmful gases like formaldehyde, to be fully adsorbed or dissolved, thus further improving the air purification effect of the water-washed air purifier.

[0065] Optionally, the second baffle plate 221 includes a first grille plate 510, a filter plate 520, and a second grille plate 530. The first grille plate 510 is recessed downward to form a receiving groove; the filter plate 520 is limited and embedded in the receiving groove, and the filter plate 520 is used to perform secondary filtration and purification on the air purified by the water curtain; the second grille plate 530 covers the receiving groove, and the filter plate 520 is located between the first grille plate 510 and the second grille plate 530; wherein, the edge of the first grille plate 510 or the second grille plate 530 is attached and fixed to the air outlet of the water tank 200.

[0066] The filter plate 520 itself has poor rigidity, and the first grid plate 510 provides support for it. The first grid plate 510 has a downward-curving groove 511 in the middle, into which the filter plate 520 is embedded. In this way, the first grid plate 510 not only supports the filter plate 520 but also limits its horizontal movement, preventing displacement. The edge of the first grid plate 510 is used to fix the water-blocking mechanism 220, either by inserting it into a slot or by attaching it to a step on the side wall of the water tank 200. This arrangement allows for better placement of the water-blocking mechanism 220 within the water tank 200. Furthermore, with this structure, the first grid plate 510 does not need to be replaced, and the filter plate 520 is a consumable. After removing the water-blocking mechanism 220, the filter plate 520 can be removed for cleaning or replacement.

[0067] The first grille plate 510 and the second grille plate 530 together fix the filter plate 520. The filter plate 520 cannot be moved in either the vertical or horizontal direction. With this arrangement, the water-blocking mechanism 220 has better overall integrity and is easier for users to disassemble and use.

[0068] Optionally, the second grating plate 530 is snapped into the first grating plate 510. This snap-fitting of the second grating plate 530 and the first grating plate 510 further improves the overall integrity of the water-blocking mechanism 220. The snap-fitting of the first grating plate 510 and the second grating plate 530 also facilitates the assembly and disassembly of the filter plate 520.

[0069] Optionally, the water-washing air purifier also includes a water collection tray located below the water tank 200 to collect water overflowing from the water tank 200. During operation, water inevitably splashes out of the water tank 200. The water collection tray collects water that falls along the guide strip 422. The water collection tray prevents water discharged from the base of the water tank 200 from flowing into the environment where the water-washing air purifier is located, thus improving user convenience.

[0070] Optionally, the water-washable air purifier also includes a housing 100, a fan box 300, and a fan. The housing 100 includes a top panel 130 with an air outlet and a water inlet, and an air inlet window 111 on the side wall of the housing 100. The fan box 300 has an air inlet and an air outlet, and includes an air guide duct 330. The air outlet of the water tank 200 is connected to the air inlet of the fan box 300. The fan is disposed inside the air guide duct and drives air to flow from the air inlet of the fan box 300 to the air outlet of the fan box 300.

[0071] In this way, the airflow path of the water-washed air purifier enters through the air inlet window 111 at the lower side wall of the housing 100, passes through the water curtain in the water tank 200, goes through the air guide tube 330, and finally blows upward from the air outlet of the upper panel 130. This avoids the problem of turbulence caused by the airflow entering and exiting on the same side, and improves the air purification efficiency.

[0072] Optionally, the water-washable air purifier also includes a display panel 326. The upper panel 130 has a through-hole, and the display panel 326 is located within the through-hole. A gap is left between the display panel 326 and the upper panel 130 to serve as a water inlet, allowing water to flow into the housing 100 through the water inlet. The upper panel 130 includes a panel body 1301 and a grille frame. The outer edge of the panel body 1301 is detachably connected to the housing 100, and the inner edge of the panel body 1301 forms a through-hole. The grille frame is located between the outer and inner edges, so that the panel forms multiple ventilation grilles.

[0073] Specifically, the display panel 326 is located on the through-hole side, forming an annular water inlet between the display panel 326 and the grille frame. The grille frame area is the air outlet area. The humidified and purified air inside the housing 100 is blown out through multiple ventilation grilles of the grille frame. In this way, the upward water inlet and upward air outlet can be carried out simultaneously without interference.

[0074] Optionally, the display panel 326 is lower than the inner edge of the upper panel 130. When water is poured in, the water first hits the display panel 326. When the water flow rate is high, water rebound is likely to occur. By positioning the display panel 326 below the upper panel 130, water can be prevented from splashing onto the outside of the water-washing air purifier.

[0075] Optionally, the display panel 326 includes a display surface 3261 and a drainage surface 3262. The display surface 3261 provides a visual display; the drainage surface 3262 is located on the outer periphery of the display surface 3261 and is inclined downwards. The display screens of related water-washing air purifiers are typically located on the side wall of the housing 100 or on the top side of the housing 100. The display panel 326 of this application not only provides a visual display through the display surface 3261, but also guides water flow through the arrangement of the display surface 3261 and the drainage surface 3262, enhancing the technological appeal and practicality of the water-washing air purifier.

[0076] Optionally, the upper surface of the grille frame is curved, forming an arc-shaped notch in the upper panel 130. This allows some of the water splashing outwards when the water flow to the display screen is too strong to be collected within the housing 100 by the curved surface of the grille frame. When the water flow velocity is high, some of the water splashing onto the curved surface can flow along its curvature into the water inlet, preventing water from splashing outwards due to excessive water flow from the user.

[0077] Optionally, the grille frame includes multiple first grille strips 1302. The two ends of each first grille strip 1302 are connected to the inner and outer edges, respectively. Each first grille strip 1302 is a downward-facing arc-shaped convex strip. In this way, the multiple first grille strips 1302 can guide water splashed onto the grille frame, while also providing an air outlet for the purified air, and are more aesthetically pleasing.

[0078] Optionally, the grid frame also includes multiple second grid strips 1303, which are fixedly connected to multiple first grid strips 1302. The multiple second grid strips 1303 provide support and fixation for the grid frame, improving its stability.

[0079] Optionally, the multiple first grille strips 1302 are arranged radially from the center outwards relative to the display panel 326. Understandably, the spacing between adjacent first grille strips closer to the display panel 326 is narrower, while the spacing between adjacent first grille strips 1302 farther from the display panel 326 is wider. This prevents water splashed from the display screen onto the far end of the upper panel 130 (the side away from the display panel 326) from falling into the housing, thus preventing secondary splashing on the upper panel 130. When water splashes from the display screen onto the near end of the upper panel 130 (the side closer to the display panel 326), the water is guided back into the water inlet by the densely distributed multiple first grille strips 1302.

[0080] Optionally, the water-washable air purifier also includes a water-blocking ring. The water-blocking ring is annular and includes an upper edge and a lower edge. The lower edge surrounds the upper edge of the air guide duct 330 and fits against the inner wall of the fan housing 300 to seal the gap between the inner wall of the fan housing 300 and the air guide duct 330. Understandably, when the flow rate or volume of water injected by the user is too high, some water will enter the housing from the air outlet. The water injected through the water inlet can eventually flow into the water tank 200 through the water flow path. By setting up the water-blocking ring, water splashed into the housing 100 from the air outlet can be prevented from falling outside the air guide duct 330, allowing water that does not enter the water flow path to fall into the air guide duct and finally drain into the water tank 200 through the drain hole 421 at the bottom of the air guide duct 330.

[0081] Optionally, the water-washing air purifier also includes a water tank base 400, which is fixed inside the housing 100. The water tank 200 is detachably mounted on the water tank base 400, and the fan housing 300 is fixed on the water tank base 400. The water tank base 400 supports the water tank 200, which is mounted on it. The water tank base 400 provides better support and fixation for the water tank 200, improving the structural stability of the water-washing air purifier.

[0082] Optionally, the water tank base 400 is provided with a drain hole 421, and a water collection tray is located below the drain hole 421. The drain hole 421 in the water tank base 400 allows water accumulated in the water tank base 400 to be drained more effectively.

[0083] Optionally, the water-washing air purifier also includes a guide strip 422 extending downward from the drain hole 421 to guide water from the water tank seat 400 downward from the drain hole 421 to the water collection tray. The water tank seat 400 has a drain hole 421 for draining water splashed from the water tank 200. Since the amount of water splashed from the water tank 200 is relatively small, it accumulates in the water tank seat 400 and slowly flows to the drain hole 421. Due to the good wetting properties of water, on the one hand, a dripping noise may occur; on the other hand, water flowing downward along the drain hole 421 may flow along the lower surface of the water tank seat 400 to other places. Therefore, a guide strip 422 is provided at the drain hole 421, extending downward from the drain hole 421 to guide the water accumulated in the water tank seat 400 downward from the drain hole 421. Water accumulating at the base of the water tank 200 flows to the vicinity of the drain hole 421, wets the guide strip 422, and moves downwards along the guide strip 422. This prevents dripping noises and prevents water from flowing to other areas. Using the water-washing air purifier provided in this embodiment, the water tank base 400 has a drain hole 421, and a guide strip 422 is provided corresponding to the drain hole 421. This not only prevents water from dripping from the drain hole 421 and producing a dripping sound, but also prevents water droplets from sliding along the lower surface of the water tank base 400 to other parts of the water-washing air purifier. This allows water accumulating in the water tank base 400 to drain more effectively, improving the user experience.

[0084] Optionally, the water tank base 400 includes a support plate 410 and a support platform 420, wherein the support plate 410 is vertically disposed in the accommodating space; the support platform 420 is fixed to the support plate 410 to support the water tank 200, a drain hole 421 is opened on the support platform 420 and close to the support plate 410, and a guide strip 422 extends inward from the support plate 410 and is located below the drain hole 421.

[0085] The support plate 410 is vertically positioned so that the support platform 420 is a certain distance from the bottom of the housing 100, thereby also placing the water tank 200 a certain distance from the bottom of the housing 100. This allows the water tank 200 to be positioned at a convenient operating height. The support platform 420 is connected to the water tank 200, contacting and supporting it. The support platform 420 includes at least one horizontally positioned plane to catch water splashed from the water tank 200. A drain hole 421 is provided on the support platform 420 to drain water accumulated thereon. This arrangement allows the water tank 200 to be positioned at a suitable height, facilitating user operation and use, and also helps to drain water accumulated in the water tank base 400. A guide strip 422 is positioned below the support platform 420 corresponding to the drain hole 421. When water falls from the drain hole 421, the support plate 410 extends horizontally below the drain hole 421 to ensure contact between the water and the support plate. This allows the water discharged through the drain hole 421 to flow in an orderly manner, thereby improving the drainage effect of the water tank base 400 of the water-washing air purifier. The guide strip 422 extends inward along the support plate 410, structurally serving as a reinforcing rib of the support plate 410, thus improving the structural strength of the water tank base 400; functionally, it also provides a flow guiding function, enhancing the drainage effect of the water tank base 400. This design facilitates the processing of the water tank base 400 and improves its structural strength.

[0086] Optionally, the drain hole 421 is located near the support plate 410, and the guide strip 422 extends inward from the support plate 410 and is positioned below the drain hole 421. The guide strip 422 is positioned below the support platform 420 corresponding to the drain hole 421. When water falls from the drain hole 421, the support plate 410 extends horizontally below the drain hole 421 to ensure that the water can contact the support plate 410. This allows the water discharged through the drain hole 421 to flow in an orderly manner, thereby improving the drainage effect of the water tank base 400 of the water-washing air purifier.

[0087] Optionally, multiple guide strips 422 are provided, arranged in parallel. The drain hole 421 is relatively large while the guide strips 422 are relatively thin. Multiple guide strips 422 can cover multiple locations directly below the drain hole 421, meaning that water flowing from any location in the drain hole 421 can contact at least one support plate 410. The presence of multiple guide strips 422 allows for better drainage from the water tank 200 base. A water collection tray is used to collect water falling along the guide strips 422. The water collection tray prevents water discharged from the water tank 200 base from flowing into the environment where the water-washing air purifier is located.

[0088] Optionally, the water collection tray is removable from the housing. Since the amount of water draining from the water tank 200 base is relatively small, the water-washing air purifier is not always operational, while the water in the collection tray continuously evaporates. The natural evaporation rate of the water in the collection tray can balance the rate of water collection, eliminating the need for manual operation. The removable design allows the collection tray to be removed and the water emptied when the natural evaporation rate is insufficient to meet the drainage requirements of the water tank 400, preventing overflow. This design enhances user convenience.

[0089] Optionally, the housing 100 is provided with a water tank 200 mounting window, and the water tank base 400 is constructed with a notch corresponding to the water tank 200 mounting window, so that the water tank 200 can be pulled out and installed in the receiving space through the water tank 200 mounting window. When it is necessary to clean or change the water in the water tank 200, the water tank 200 can be pulled out, and after cleaning, the water tank 200 can be pushed back into the receiving space through the water tank 200 mounting window. This configuration facilitates user operation.

[0090] Optionally, the first baffle plate 222 is a U-shaped baffle plate, with its U-shaped opening corresponding to the water tank 200, so that the water tank 200 can be pushed into the water tank seat 400 or pulled out from the water tank seat 400 by a horizontal pull-out motion from the side of the housing 100. This makes it convenient for the user to remove the water tank 200.

[0091] Optionally, the bottom of the first baffle plate 222 facing the water curtain generating unit 210 is provided with a baffle 223, so that the inner side of the first baffle plate 222 forms a U-shaped groove with open ends. The water curtain generated by the water curtain generating unit 210 collides and splashes onto the first baffle plate 222 to form a water flow. The water flow is guided through the U-shaped groove and flows out from the open ends of the U-shaped groove to avoid the airflow on the air inlet side of the water tank 200. If the baffle 223 is not provided, after the water curtain sprays onto the first baffle plate 222, it flows downward along the first baffle plate 222. The downward flowing water forms a water curtain along the first baffle plate 222. The water curtain and the water curtain form two spaces inside the water tank. In this way, the airflow on the air inlet side of the water tank 200 needs to pass through the water curtain before passing through the water curtain, which reduces the airflow volume and wind speed and causes more noise. By setting the U-shaped baffle 223, the water flow can be gathered from both ends and flow into the water tank 200 along the U-shaped groove, which greatly increases the air intake speed, reduces wind noise and water flow noise, and improves the user experience.

[0092] Optionally, the water-washable air purifier also includes a fan bracket 320, which is fixed inside the fan box 300. The fan bracket 320 is used to fix the fan. The fan bracket 320 includes a tray and a guide pipe. The tray is located below the water inlet, and one end of the guide pipe is connected to the tray, while the other end extends to the water tank 200.

[0093] Optionally, the fan bracket 320 includes a tray 321, a guide pipe 323, and support legs 322. The tray 321 has a water storage space at its top, and the fan is fixed to the bottom of the tray 321. The guide pipe 323 connects to the water storage space at one end and extends to the water tank 200 at the other end. One end of the support leg 322 is connected to the side wall of the fan housing 300, and the other end is connected to the tray 321. Multiple support legs 322 are used to fix the tray above the air inlet of the fan housing 300. This creates an air outlet channel through the space between the multiple support legs 322, preventing interference between the water flow path and the air flow path, thus improving space utilization.

[0094] Optionally, the fan housing 300 includes a base plate, side plates 110, and an air guide duct 330, wherein an air inlet is provided in the middle of the base plate; the side plates 110 and the base plate enclose the fan installation space. The air guide duct 330 extends upward from the base plate of the fan housing 300, with the bottom opening serving as the air inlet of the fan housing 300, and the top opening being smaller than the top opening.

[0095] When the fan rotates, it throws the fan at its location to the surrounding areas, creating a low-pressure zone around the fan and a high-pressure zone around it. An air outlet is located near the side wall of the upper panel 130, connecting to the surrounding high-pressure zones. The external environment of the air outlet is at normal pressure, resulting in a pressure difference. Driven by this pressure difference, air inside the fan box 300 flows from the high-pressure zone to the outside of the fan box 300. The air inlet of the fan box 300 is located on the bottom plate in the middle, in a low-pressure zone. The air inside the water tank 200 is at normal pressure, and there is a pressure difference at the air inlet of the fan box 300. Driven by this pressure difference, air in the water tank 200 passes through the water curtain generated by the water curtain generating unit 210 and enters the fan box 300. In this way, air continuously enters the fan box 300 from the air inlet at the bottom and exits from the air outlet, driving the air to flow within the water washing and purification device. This arrangement allows water droplets in the air entering the fan box 300 to be separated, thus preventing the water in the exhaust air from affecting the cleanliness of the surrounding environment.

[0096] Optionally, the air duct 330 is vertically provided with a support column 331, and the top of the support column 331 is provided with a fixing groove. The side plate 110 of the fan box 300 extends inward and is provided with a fixing part 112, which is engaged with the fixing groove of the support column 331. The fan bracket 320 includes a tray 321 and a support leg 322. One end of the support leg 322 is fixed to the top of the support column 331 and covers the fixing groove, and the other end is fixed to the tray 321.

[0097] In this embodiment, the water-washing air purifier is used to purify the air. A vertically arranged support column 331 is provided on the air duct 330, and a fixing groove is formed at the top of the support column 331. A fixing part 112 extends inward from the side plate 110 and engages with the fixing groove at the top of the support body, thereby fixing the side plate 110. The fan bracket 320 is fixed to the support column 331 by a support leg 322, thereby fixing the fan bracket 320. Using the water-washing air purifier provided in this embodiment, the air duct is equipped with a support column 331, and the fixing groove at the top of the support column 331 simultaneously fixes both the side plate 110 and the fan bracket 320, resulting in a reasonable stress distribution and a stable structure.

[0098] Optionally, the bottom of the fan housing 300 extends upward with a snap-fit ​​edge 332, and the bottom end of the side plate 110 abuts against the inner surface of the snap-fit ​​edge 332. The side plate 110 extends inward with a fixing part 112, and the force on the side plate 110 is concentrated only through this fixing part 112. The bottom of the air duct 330 extends outward beyond the duct body and also extends upward with a snap-fit ​​edge 332. The bottom end of the side plate 110 snaps against the snap-fit ​​edge 332, which provides vertical support for the side plate 110. Simultaneously, the bottom end of the side plate 110 abuts against the inner surface of the snap-fit ​​edge 332, and a baffle provides lateral restraint to the bottom end of the side plate 110. In this case, the bottom end of the side plate 110 and the location where the fixing part 112 is provided are simultaneously fixed by the fixing of the extension of the side plate 110, restricting the displacement of the side plate 110 in both the horizontal and vertical directions. This more rational stress structure allows for better fixation of the side plate 110, further improving the structural stability of the water-washed air purifier.

[0099] Optionally, the support leg 322 is connected to the fixed column by screws. One end of the support leg 322 fits into the fixing groove on the top of the support column 331, and the support leg 322 is fixed in place by screws. The structure is simple and the fixing effect is good. The bolts can be removed and installed through the opening on the top of the fan box 300 for easy operation. While fixing the support leg 322 and the bolts, the side plate 110 is also fixed. This configuration facilitates the assembly and disassembly of the water-washable air purifier and reduces the processing and manufacturing cost of the water-washable air purifier.

[0100] Optionally, the screw passes through the support leg 322, the fixing part 112 of the side plate 110, and the support column 331 in sequence. One end of the support leg 322 covers the fixing groove at the top of the support column 331. Although fixing the support leg 322 is sufficient to fix the side plate 110, the simultaneous penetration of the screw through the extension of the side plate 110 provides a double guarantee mechanism for fixing the side plate 110, allowing for better fixation of the side plate 110.

[0101] Optionally, there are multiple support columns 331, which are spaced apart along the circumference of the ventilation. There are multiple side plates 110, each of which extends inward and is provided with a fixing part 112. The air duct 330 is located within the space defined by the multiple side plates 110.

[0102] The fan bracket 320 suspends and fixes the fan in the middle of the fan housing 300. Multiple support columns 331 allow the multiple legs 322 of the fan bracket 320 to fix the tray 321 to the middle of the fan housing 300 in a spoke-like manner, further securing the fan below the tray 321. Multiple side panels 110 are assembled together. This design further facilitates the assembly and disassembly of the water-washable air purifier, making it more convenient for users.

[0103] Optionally, the side plate 110 extends and is provided with multiple fixing parts 112, which are correspondingly engaged with the fixing grooves of multiple support columns 331. With this arrangement, the upper part of the side plate 110 is fixed by multiple fixing parts 112, which can make the fixing of the side plate 110 more stable.

[0104] Optionally, the water-washing air purifier also includes a fan, fixed to a fan bracket 320, used to drive air to flow from the air inlet to the air outlet of the fan housing 300. The fan is vertically positioned; when it rotates, it throws the air in the center outwards, creating a low-pressure zone in the center and a high-pressure zone around the edges. Air moves from the low-pressure zone to the high-pressure zone of the fan housing 300. The air inlet of the fan housing 300 is connected to the air outlet of the water tank 200. Water droplets entering the fan housing 300 from the water tank 200 with the air are thrown from the center to the high-pressure zones around the edges by the fan. The water droplets have a relatively high specific gravity and inertia, making them easy to adhere to the side walls of the fan housing 300. The air outlet is located at the top of the fan housing 300, and the air from the high-pressure zones around the edges flows out of the air outlet of the fan housing 300 under the influence of the pressure difference. Water droplets are adsorbed by the side walls, accumulate, increase in volume, and slide to the bottom of the fan housing 300. The fan housing 300 is located on top of the water tank 200. The air in the fan housing 300 moves from bottom to top, making it difficult for water droplets in the fan housing 300 to enter the environment where the water-washing air purifier is located through the air outlet of the fan housing 300. The fan is set vertically, throwing the air in all directions, which helps the water droplets in the fan housing 300 to be adsorbed by the side walls of the fan housing 300, thus preventing the water droplets from being thrown out of the air outlet of the housing.

[0105] Optionally, the fan includes a motor 311, a connecting plate 312, multiple blades 313, and an air-guiding ring 314. The motor 311 is located above the air inlet of the fan box 300, and its output shaft is vertically oriented. The connecting plate 312 is fixed to the output shaft of the motor 311. The multiple blades 313 are connected to the connecting plate 312 and distributed circumferentially along the motor 311. When the motor 311 rotates, the multiple blades 313 drive the air to move radially outward along the motor 311. The air-guiding ring 314 is connected to the bottom of the multiple blades 313.

[0106] Motor 311 provides power for the rotation of blades 313. When motor 311 rotates, blades 313 drive air to rotate, causing air to move from the fan location to the surrounding areas under the action of centrifugal force, thus forming a central low-pressure zone and a surrounding high-pressure zone within the fan housing 300. The induced draft ring 314 facilitates the fixing of multiple blades 313. Furthermore, the induced draft ring 314 defines the air inlet in the central low-pressure zone, thereby making the airflow more orderly.

[0107] Optionally, the air-drawing ring 314 extends downward from the bottom of the multiple blades 313. When the motor 311 rotates, the air-drawing ring 314 rotates together with the blades 313. Because the air-drawing ring 314 extends downward and its bottom is a certain distance from the blades 313, the air at the bottom of the air-drawing ring 314 is less affected by the airflow near the blades 313, thus allowing it to be better drawn into the fan blades 313 under the negative pressure of the air-drawing ring 314. This arrangement not only improves the structural strength of the fan but also enhances the air-drawing effect of the air-drawing ring 314.

[0108] Optionally, the air duct 330 extends upward from the bottom of the fan housing 300, with the bottom opening serving as the air inlet of the fan housing 300 and the top opening corresponding to the air intake ring 314. When the fan rotates, it throws the airflow at the fan location to the surrounding areas. The fan location is a low-pressure zone, and the surrounding area is a high-pressure zone. The upper panel 130 has an air outlet near the side wall, which connects to the surrounding high-pressure zones. The external environment of the air outlet is at normal pressure, thus creating a pressure difference at the air outlet. Driven by this pressure difference, the air inside the fan housing 300 flows from the high-pressure zone of the fan housing 300 to the outside of the fan housing 300. The air inlet of the fan housing 300 is located on the bottom plate in the middle, in the low-pressure zone. The air inside the water tank 200 is at normal pressure, and there is a pressure difference at the air inlet of the fan housing 300. Driven by the pressure difference, air in the water tank 200 passes through the water curtain generated by the water curtain generating unit 210 and enters the fan box 300. Thus, air continuously enters the fan box 300 from the air inlet at the bottom and exits from the air outlet, driving air flow within the water-washing air purifier. This design allows water droplets in the air entering the fan box 300 to be separated, thereby preventing the water in the air outlet from affecting the cleanliness of the surrounding environment.

[0109] The air guide duct 330 is a cylindrical structure, vertically arranged. The diameter of the air guide duct 330 gradually decreases from bottom to top. The opening at the bottom of the air guide duct 330 is used to introduce air from the water tank 200 into the fan housing 300. The opening at the top of the air guide duct 330 serves as the air inlet of the fan housing 300 and / or the air outlet of the water tank 200. The inner wall of the air guide duct 330 acts as a guide, directing air from the water tank 200 into the fan housing 300. The outer wall of the air guide duct 330 forms a water-collecting groove with the bottom plate and side wall of the fan housing 300, which is used to collect water falling along the side wall of the fan housing 300. The opening at the top of the air guide ring corresponds to the air intake ring 314, that is, it is located below the air intake ring 314, in the central negative pressure zone of the fan housing 300. In this way, the air in the water tank 200 can enter the fan box 300 along the air guide duct 330 under the negative pressure of the fan box 300.

[0110] Optionally, the upward extension of the air guide duct 330 is inserted into the air intake ring 314. The air guide duct 330 and the air intake ring 314 partially overlap in the vertical direction. This acts as a backflow preventer for the air in the fan housing 300. Specifically, when the fan rotates, the air in the fan housing 300 moves from the fan to the periphery of the fan housing 300. There is a pressure difference between the low-pressure area in the center and the high-pressure areas around the periphery, and some air may return from the high-pressure areas around the periphery to the low-pressure area in the center. The upward extension of the air guide duct 330 into the air intake ring 314 stops the horizontal movement of air, thus providing a backflow preventer to some extent. Furthermore, even if air still enters the multiple blades 313 of the fan through the gap between the air guide ring and the air intake ring 314, this air moves upwards, and under the entrainment effect of this air, the air in the air guide duct 330 can be guided upwards. This configuration allows the air in the water tank 200 to enter the fan box 300 more effectively.

[0111] Optionally, the water-washable air purifier also includes a negative ion generator 700, located in the fan housing 300. Negative ions are generated through the pulse oscillation circuit of the negative ion generator 700, which boosts low voltage to a DC negative high voltage via a high-voltage module. This voltage is then continuously generated by a negative DC high corona discharge at the tip of the carbon fiber, resulting in a large number of electrons emitted at high speed. These electrons cannot remain in the air for long and are immediately captured by oxygen molecules, forming negative ions. These ions can neutralize positively charged smoke and dust particles floating in the air, causing them to settle naturally. The working principle of the negative ion generator 700 is consistent with the phenomenon of negative ions being generated during natural phenomena such as thunder and lightning. Negative ions are ubiquitous in nature. Thunder and lightning, plant photosynthesis, and the impact of waterfalls can all generate large amounts of negative ions, which is why people feel the air is fresh during thunderstorms, in forests, and near waterfalls. The negative ion generator 700 is used to generate negative ions, and its inclusion enhances the air purification effect of the water-washable air purifier, improves air quality, and enhances the user experience.

[0112] Optionally, the water-washable air purifier also includes a panel bracket 325 extending upwards from the tray 321; a display panel 326 is fixed to the panel bracket 325, and the display panel 326 is a waterproof panel, with water flowing down the waterproof panel into the tray 321. Specifically, the tray 321 is fixed to the fan bracket 320. When adding water to the water-washable air purifier, water is poured onto the display panel 326, flows down the display panel 326 into the tray 321, and then flows down the guide pipe 323 into the water tank 200. This design allows the panel to be rinsed when adding water, and the method of water pouring along the panel differs from conventional water filling methods, breaking the misconception that the panel cannot be touched, making the water-washable air purifier more technologically advanced and futuristic.

[0113] Optionally, the water-washable air purifier also includes a filter assembly 800, which is disposed in the sandwich duct formed by the water tank 200 and the housing 100, for filtering the air passing through the sandwich duct.

[0114] The housing 100 encloses the water tank 200, and the housing 100 is at a certain distance from the side wall of the water tank 200 where the air inlet is located, thus forming a sandwich air duct with the side wall of the water tank 200. Air passes through the sandwich air duct and enters the water tank 200 from the air inlet. The filter assembly 800 is disposed within the sandwich air duct to filter the air entering the water tank 200. Using the water-washing air purifier provided in this embodiment, the filter assembly 800 works in conjunction with the water curtain to purify the air, which can improve the air purification effect of the water-washing air purifier.

[0115] Optionally, the filter element 800 is interference-fitted with the retaining space. This design, relying on the filter element 800's own elastic retaining space, is simple in structure, easy to implement, and can reduce the cost of water-washable air purifiers.

[0116] Optionally, the side panel 110 is provided with a plurality of air inlets 111 spaced apart along the circumference of the water tank 200, and the filter assembly 800 is provided corresponding to the plurality of air inlets 111. The provision of a plurality of air inlets 111 on the side panel 110 can reduce the air resistance of the interlayer air duct and increase the air volume of the water-washed air purifier. The filter assembly 800 is provided corresponding to the plurality of air inlets 111, which can better filter the air and further improve the air purification effect of the water-washed air purifier.

[0117] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them.
