Description

Technical Field

[0001] This invention relates to the field of air purification technology, and more specifically to an air cleaner. Background Technology

[0002] Air cleaners are a type of air purification equipment, which refers to products that filter out or kill air pollutants and effectively improve air cleanliness. They are mainly used to remove indoor air pollution.

[0003] Chinese patent CN118582804A discloses an air cleaner, which includes a shell, a volute, a first partition, a lower water tank, a first water baffle, a second water baffle, an upper water tank, a third water baffle, a water impeller, a waterfall plate, a first pump, a front washing plate, a first drain plate, a second drain plate, a sewage pump, a centrifugal impeller, a filter bracket, a second partition, a controller, a second pump, a filter, a rotating shaft, a base plate, and a motor. During operation, the second pump delivers water to the lower water tank, and the water is sprayed onto the water impeller through holes at the bottom of the lower water tank. The water impeller is driven to rotate at high speed by the rotating shaft.

[0004] While this method allows water and air to mix to some extent, the water is only sprayed onto the water wheel from one direction, resulting in uneven water distribution. This still fails to effectively mix the air and water, leading to poor cleaning results and low cleaning efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an air cleaner to solve the problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An air cleaner includes a base, a housing, a water tank, a water flow plate, an air inlet grille, a water deflector, a centrifugal fan, and an air outlet grille. The housing is mounted on the base, and the water tank is disposed inside the housing and fixedly mounted on the base. The water tank contains a first water pump for supplying water to the water flow plate and a second water pump for supplying water to the water deflector. The water flow plate is disposed on the side of the housing. One side of the air inlet grille is connected to the water flow plate, and the other side is connected to the housing. The water deflector and the centrifugal fan are both disposed inside the housing, with the water deflector located above the water tank and the centrifugal fan located below the air outlet grille. The air outlet grille is disposed on the top of the housing. The water-pushing wheel includes a drive motor, a water turbine disc, water turbine blades, an annular water inlet chamber, and water spraying components. Multiple water turbine discs are evenly arranged along the axial direction of the output shaft of the drive motor. Multiple water turbine blades are evenly arranged along the surface of the water turbine discs. The water turbine blades on adjacent water turbine discs are staggered. Multiple water spraying components are evenly arranged on the annular water inlet chamber and are connected to it. The number of water spraying components is the same as the number of water turbine blades on each water turbine disc and is arranged accordingly. Multiple water spray holes are provided on the side of each water spraying component near the water turbine blades.

[0007] Furthermore, the water tank has an opening at the top, and an installation platform is provided on the outer ring of the top of the water tank. A support frame is provided on the installation platform, and the water wheel and the centrifugal fan are both installed on the support frame.

[0008] Furthermore, the water wheel also includes an annular cleaning chamber located outside the water wheel disc. One end of the annular cleaning chamber is connected to the support frame, and the other end is connected to the annular water inlet chamber. The drive motor is connected to the support frame via a mounting base.

[0009] Furthermore, one end of the water spraying component is connected to the annular water inlet cavity, and the other end extends to the outside of the annular cleaning chamber. A through groove is provided on the outer wall of the annular cleaning chamber at a position corresponding to the water spraying hole of the water spraying component. Water in the water spraying component enters the annular cleaning chamber in sequence through the water spraying hole and the through groove.

[0010] Furthermore, the annular water inlet chamber is connected to the outlet end of the second water pump via a first water pipe.

[0011] Furthermore, the bottom of the flow plate is mounted on the mounting platform, and the top is connected to the top plate of the outer casing. An LED light strip is provided on the upper part of the flow plate.

[0012] Furthermore, a water outlet component is installed on the upper part of the water flow plate, and multiple partitions are provided below the water outlet component on the water flow plate. The water outlet component is connected to the water outlet end of the first water pump through a second water pipe. Multiple water outlet holes are provided at the bottom of the water outlet component, and each water outlet hole is located between two adjacent partitions.

[0013] Furthermore, the water flow plate is a corrugated plate, the lower part of the water flow plate is provided with a water leakage grille, the lower part of the water leakage grille is provided with a filter groove, and the part of the water flow plate corresponding to the filter groove is provided with a return water outlet to the water tank.

[0014] Furthermore, an air filter is provided on the support frame at the air inlet of the centrifugal fan, the air outlet of the centrifugal fan is located below the air outlet grille, and the support frame is provided with ventilation holes.

[0015] Furthermore, the water tank is equipped with an ultraviolet lamp.

[0016] Compared with the prior art, the beneficial effects of the present invention are: By setting multiple water turbine blades on each water turbine disc and evenly arranging multiple water turbine discs along the axial direction of the drive motor output shaft, a multi-layer water turbine blade structure is formed. Multiple water spray components are evenly arranged on the annular water inlet cavity, with the water spray components corresponding to the water turbine blades. This ensures that each water turbine blade in each layer has a corresponding water spray component, which can spray water onto each water turbine blade from different directions, resulting in a particularly uniform water distribution. Ultimately, this allows for better mixing of air and water, thereby cleaning the air, resulting in better cleaning effect and higher cleaning efficiency. Attached Figure Description

Detailed Implementation

[0036] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] Combination Figures 1 to 18 This embodiment provides an air cleaner, including a base 1, a shell 2, a water tank 3, a water flow plate 4, an air inlet grille 5, a water deflector 6, a centrifugal fan 7, an air outlet grille 8, a support frame 9, and a controller 10. The outer casing 2 is mounted on the base 1. The water tank 3 is located inside the outer casing 2 and fixedly mounted on the base 1. The water tank 3 contains a first water pump 31 for supplying water to the water flow plate 4 and a second water pump 32 for supplying water to the water-dispensing wheel 6. The water flow plate 4 is located on the side of the outer casing 2. One side of the air intake grille 5 is connected to the water flow plate 4, and the other side is connected to the outer casing 2. The water-dispensing wheel 6 and the centrifugal fan 7 are both located inside the outer casing 2. The water-dispensing wheel 6 is located above the water tank 3, and the centrifugal fan 7 is located below the air outlet grille 8. The air outlet grille 8 is located on the top of the outer casing 2. The top of the water tank 3 has an opening, and the outer ring of the top of the water tank 3 has an installation platform 33. A support frame 9 is installed on the installation platform 33. The water-dispensing wheel 6 and the centrifugal fan 7 are both installed on the support frame 9. The controller 10 is electrically connected to the water-dispensing wheel 6, the centrifugal fan 7, the first water pump 31, and the second water pump 32 respectively, and is used to control their opening and closing.

[0038] like Figure 8-13 As shown, in this embodiment, the water-pushing wheel 6 includes a drive motor 61, a water wheel disc 62, water wheel blades 63, an annular water inlet chamber 64, water spray components 65, and an annular cleaning chamber 66. Multiple water wheel discs 62 are evenly arranged along the axial direction of the output shaft of the drive motor 61. Multiple water wheel blades 63 are evenly arranged along the surface of the water wheel discs 62, with the water wheel blades 63 on adjacent water wheel discs 62 being staggered. Multiple water spray components 65 are evenly arranged on the annular water inlet chamber 64 and are connected to it. The number of water spray components 65 is the same as the number of water wheel blades 63 on each water wheel disc 62 and they are correspondingly arranged. Multiple water spray holes 651 are provided on the side of the water spray component 65 closest to the water wheel blades 63. The annular cleaning chamber 66 is located outside the water wheel disc 62. One end of the annular cleaning chamber 66 is connected to the support frame 9, and the other end is connected to the annular water inlet chamber 64. The drive motor 61 is connected to the support frame 9 via a mounting base. The annular water inlet chamber 64 is connected to the outlet end of the second water pump 32 via a first water pipe 35.

[0039] In this scheme, the second water pump 32 sends water from the water tank 3 into the annular inlet chamber 64 through the first water pipe 35, and then into each spray component 65. The water flow is sprayed out through the spray hole 651 onto the water wheel blades 63. At this time, the drive motor 61 drives the water wheel disc 62 and the water wheel blades 63 to rotate, which can further agitate the water. Because multiple spray components 65 and multiple layers of water wheel blades 63 are set, and each water wheel blade 63 in each layer has a corresponding spray component 65, water can be sprayed onto each water wheel blade 63 from different directions, making the water distribution particularly uniform. Ultimately, the air and water can be better mixed, thereby cleaning the air, resulting in better cleaning effect and higher cleaning efficiency.

[0040] Specifically, such as Figure 11-13As shown, each water turbine disc 62 has four water turbine blades 63, four water spray components 65, and three water turbine discs 62. This is equivalent to having three layers of water turbine blades 63 arranged sequentially from the inside to the outside along the axial direction of the output shaft of the drive motor 61. The water turbine blades 63 of adjacent layers are staggered, that is, the angle difference between the water turbine blades 63 on the outermost layer of water turbine disc 62 and the water turbine blades 63 on the middle layer of water turbine disc 62 is 45°, and the angle difference between the water turbine blades 63 on the middle layer of water turbine disc 62 and the water turbine blades 63 on the innermost layer of water turbine disc 62 is 45°.

[0041] Preferably, one end of the water spray component 65 is connected to the annular water inlet cavity 64, and the other end extends to the outside of the annular cleaning chamber 66. A through groove is provided on the outer wall of the annular cleaning chamber 66 at the position corresponding to the water spray hole 651 of the water spray component 65. Water in the water spray component 65 enters the annular cleaning chamber 66 in sequence through the water spray hole 651 and the through groove.

[0042] In this embodiment, the bottom of the flow plate 4 is mounted on the mounting platform 33, and the top is connected to the top plate of the outer casing 2. An LED light strip is provided on the upper part of the flow plate 4.

[0043] like Figure 14-16 As shown, a water outlet component 41 is installed on the upper part of the water flow plate 4. Multiple baffles 42 are located below the water outlet component 41 on the water flow plate 4. The water outlet component 41 is connected to the outlet end of the first water pump 31 via a second water pipe 43. Multiple water outlet holes are located at the bottom of the water outlet component 41, with each hole situated between two adjacent baffles 42. The water flow plate 4 is made of corrugated plate. A water leakage grille 44 is located at the lower part of the water flow plate 4. A filter tank 45 is located below the water leakage grille 44. A return water inlet 46 is located on the water flow plate 4 at a position corresponding to the filter tank 45, leading to the water tank 3.

[0044] In this scheme, the first water pump 31 sends water from the water tank 3 to the water outlet component 41 through the second water pipe 43. The water outlet component 41 discharges the water through the water outlet hole at its bottom, which flows downward along the corrugated structure of the water flow plate 4, forming a water curtain. The water then flows into the water tank 3 through the water leakage grille 44, the filter tank 45, and the return water outlet 46. During this process, the filter tank 45 is filled with filter media, which can filter impurities in the water that has been used to clean the air, so that the water flowing back into the water tank 3 is purified.

[0045] As a preferred option, such as Figure 4As shown, an air filter 91 is installed on the support frame 9 at the air inlet of the centrifugal fan 7, and the air outlet of the centrifugal fan 7 is located below the air outlet grille 8. The support frame 9 also has ventilation holes 92. With this design, after air is purified by the water deflector 6, it passes through the ventilation holes 92 through the support frame 9 and reaches the air filter 91. The air filter 91 further filters the air, effectively improving air cleanliness, and finally, the air is discharged through the centrifugal fan 7 and the air outlet grille 8.

[0046] As a preferred option, such as Figure 18 As shown, a UV lamp 34 is installed inside the water tank 3. Using this method, the UV lamp 34 emits ultraviolet light to disinfect the water in the water tank 3.

[0047] Working principle: Analysis of the core structure of the water-washing air purifier: The three-layer staggered spiral structure of the water-dispensing wheel 6 can "clean up every wisp of air that enters it".

[0048] I. Core Structure: The waterwheel 6 comprises a three-layer Archimedean spiral waterwheel disc 62 and waterwheel blades 63, which incorporates the ingenious design of "purification without dead angles." The core of the purification is the three-layered Archimedean spiral waterwheel disc 62 and waterwheel blades 63, each layer designed to "completely intercept pollutants." Each waterwheel disc 62 has 4 Archimedean spirals (waterwheel blades 63), like 4 "small wings that evenly distribute water", installed diagonally symmetrically, which can throw water evenly and far when rotating; The three-layer water turbine blades 63 are not simply stacked together, but are "deliberately staggered by 45 degrees": the spirals of the first and second layers differ by 45 degrees, and the second and third layers differ by another 45 degrees, which is equivalent to "three-dimensionally staggering" adjacent spirals, weaving a "seamless water net" from the four directions of up, down, left, and right.

[0049] II. Working Process: "Water Spraying → Rotation → Net Weaving → Stain Encapsulation"—a one-step purification logic. The whole process is like giving the air a "full body wash," with each step precise and efficient: 1. Water is precisely applied: The water spray hole 651 sprays water directly onto the inside of the spiral (water wheel blade 63) - this is the place where the water wheel rotates with the most force, and the water is firmly "held" as soon as it touches the spiral; 2. Three-layer water curtain is formed simultaneously: the drive motor 61 drives the three-layer water turbine 62 to rotate at high speed, and the spiral water turbine blades 63) throw water out in the tangential direction: the first layer throws out the "bottom water curtain", the second layer throws out the "middle water curtain" in a staggered manner, and the third layer throws out the "top water curtain" in a staggered manner. The three layers of water curtains intertwine to form a "cylindrical three-dimensional water network". 3. Air is “forced to take a bath”: Polluted air passes through this “water network cylinder” and dust particles are “fully enveloped” by three layers of water curtain as soon as they enter, so that no air can escape through the gaps.

[0050] III. Compared with ordinary structures: Why is the three-layer staggered design "more efficient"?

[0051] Ordinary single-layer waterwheels can only create a single layer of flat water curtain, allowing air to easily "circle around" from the top and bottom, resulting in blind spots in purification. This patented three-layer staggered water wheel: the three-dimensional water network directly "frames" the air in the middle, so no matter which direction the air comes from, it must "pass through three layers of water curtain". In addition, the Archimedes spiral has the characteristic of "even water throwing", so pollutants cannot escape at all. The purification efficiency is more than 3 times higher than that of ordinary impellers.

[0052] Each layer of the waterwheel 62 has four Archimedean spirals that resemble 'spiral wings', which are diagonally opposite each other. Moreover, the three layers are staggered: the first and second layers are 45 degrees apart, and the second and third layers are another 45 degrees apart, which is equivalent to the three layers of 'wings' being staggered vertically without overlapping gaps. The water spray nozzles spray water directly onto the inside of the spiral. When the drive motor turns, the three water wheel discs 62 rotate at high speed together, and the spiral throws the water out. The first layer throws out a water curtain, the second layer throws out another layer in the middle, and the third layer throws out another layer on top. The three water curtains weave together a 'cylindrical water net'. When polluted air passes through this water network, it's like entering a 'water curtain cave.' Whether it's dust, bacteria, or viruses, they all have to pass through three layers of water curtains and are almost entirely enveloped and carried away by the water. Unlike ordinary machines that only have one layer of water curtain, allowing air to bypass it, the staggered design of the three layers ensures that every breath of air is washed, which is why it purifies so thoroughly.

[0053] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
