Description

Technical Field

[0001] The present application relates to the technical field of water washing and humidification, and in particular to a water washing blade, a water washing wheel and a water washing device. Background Art

[0002] Currently, water-washing purifiers are air purifiers with a humidification function added to them. The water-washing wheel rotates to roll up water in the water tank to form a water film. As the air passes through the water film, it is washed and humidified, effectively settling various inhalable suspended particulate matter in the air, such as dust, soot, smoke, and fiber impurities. However, the specific structure of the rotor blades in the water-washing wheel makes it difficult to form a water film, resulting in poor water-washing humidification effect.

[0003] In the related technology, there is a water wheel blade for a water washing purifier, which is a disc with an axial hole in the center of the blade. Several water hanging grooves are respectively opened on both sides of the blade. The aforementioned water hanging grooves are filled with the annular side space radiating from the axial hole to the periphery of the blade. Each water hanging groove has the same depth, and there is one or more protruding columns on both sides of the blade.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] The water hanging trough is a groove structure opened along the two sides of the blade. When the blade rotates, it is still difficult to roll up water to form a water film, resulting in poor water washing and humidification effect.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0042] Unless otherwise stated, the term "plurality" means two or more.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0044] Combine Figures 1-11 As shown, in some embodiments, a water-washing blade includes: a blade body 100, a first tetrahedral protrusion 200, and a second tetrahedral protrusion 300. A plurality of first tetrahedral protrusions 200 are provided, and the plurality of first tetrahedral protrusions 200 are evenly distributed on one side wall of the blade body 100; a plurality of second tetrahedral protrusions 300 are provided, and the plurality of second tetrahedral protrusions 300 are evenly distributed on the other side wall of the blade body 100.

[0045] The water-washing blade provided by the disclosed embodiment has multiple first and second tetrahedral protrusions 200 and 300 disposed on both side walls of the blade body 100. These multiple first and second tetrahedral protrusions 200 and 300 provide multiple water-lifting surfaces, thereby increasing the area of ​​contact with water. The multiple first and second tetrahedral protrusions 200 and 300 distributed on both side walls of the blade body 100 effectively roll up water to form a water film, thereby improving the water-washing and humidification effect.

[0046] Optionally, the number of the first tetrahedral protrusions 200 and the second tetrahedral protrusions 300 are the same. In this way, the number of the first tetrahedral protrusions 200 and the second tetrahedral protrusions 300 provided on the two side walls of the blade body 100 is the same. When the blade body 100 rotates, the two side walls can evenly roll up water to form a water film, thereby improving the uniformity of the water film formed circumferentially on the blade body 100 and enhancing the water washing and humidification effect.

[0047] Optionally, each first tetrahedral protrusion 200 is integrally formed with the blade body 100. This allows for greater connection stability between the first tetrahedral protrusion 200 and the blade body 100, and prevents the first tetrahedral protrusion 200 from being easily detached by water when the blade body 100 rotates for a long period of time.

[0048] Optionally, each second tetrahedral protrusion 300 is also integrally formed with the blade body 100. This makes the connection between the second tetrahedral protrusion 300 and the blade body 100 more stable, and when the blade body 100 rotates for a long time, the second tetrahedral protrusion 300 is not easily detached by water.

[0049] For example, in the water-washed blade production stage, the blade body 100, the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are generated by integral molding casting through a mold. The cast blade body 100, the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are an integrally formed structure with low production cost.

[0050] Optionally, the blade body 100 has a disc-shaped structure, with multiple first tetrahedral protrusions 200 evenly distributed on one axial side wall of the blade body 100, and multiple second tetrahedral protrusions 300 evenly distributed on the other axial side wall of the blade body 100. Thus, by configuring the blade body 100 as a disc-shaped structure, and respectively disposing multiple first tetrahedral protrusions 200 and multiple second tetrahedral protrusions 300 on both axial sides of the disc-shaped blade body 100, the rolled-up water spray forms a water film on the periphery of the blade body 100, thereby better washing and humidifying the air passing through.

[0051] Optionally, a raised clamping column 110 is provided on one axial side wall of the blade body 100, and a raised sleeve 120 is provided on the other axial side wall of the blade body 100. When multiple water-washing blades are assembled, the raised clamping columns 110 of adjacent blade bodies 100 are engaged with the raised sleeve 120. In this way, by respectively providing the raised sleeve 120 and the raised clamping column 110 on both side walls of the blade body 100, when multiple water-washing blades are assembled, the raised clamping columns 110 of adjacent blade bodies 100 can be engaged with the raised sleeve 120, thereby achieving assembly and position limiting, improving the assembly stability of the multiple water-washing blades, and enabling the multiple water-washing blades to rotate synchronously, thereby better forming a water film on their peripheries to wash and humidify the air passing through.

[0052] Optionally, a plurality of raised clamping columns 110 are provided on one axial side wall of the blade body 100, and the plurality of raised clamping columns 110 are evenly distributed around the axis of the blade body 100. A plurality of raised sleeves 120 are provided on the other axial side wall of the blade body 100, and the plurality of raised sleeves 120 are also evenly distributed around the axis of the blade body 100. In this way, the coordination of the plurality of raised clamping columns 110 and the plurality of raised sleeves 120 can further improve the stability of the plurality of water-washing blades during assembly.

[0053] Optionally, an axial hole 130 is provided at the axis center of the blade body 100. Thus, by providing the axial hole 130 at the axis center of the blade body 100, it is convenient to assemble the blade bodies 100 of a plurality of water washing blades through the axial hole 130.

[0054] Optionally, the shaft hole 130 is a regular hexagonal through-hole structure. In this way, the shaft hole 130 with a regular hexagonal through-hole structure can play a role of limiting during assembly, thereby improving the stability of the blade body 100.

[0055] Combine Figure 4 As shown, in one embodiment, the plurality of first tetrahedral protrusions 200 and the plurality of second tetrahedral protrusions 300 are both regular triangular pyramid structures.

[0056] In the disclosed embodiment, since the base of the regular triangular pyramid structure is a regular triangle and the three side surfaces are isosceles triangles of equal size, the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are both configured as regular triangular pyramid structures. This provides a more stable connection between the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 and the blade body 100. When the blade body 100 rotates, the three upper side surfaces of the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 that come into contact with water can more evenly roll up water to form a water film, thereby improving the water washing and humidification effect.

[0057] Optionally, the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are of the same size. In this way, the water splashes rolled up on both sides of the blade body 100 are more uniform, and the size and thickness of the water film formed in the circumferential direction of the blade body 100 are more uniform.

[0058] It can be understood that the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are of the same size, which means that the bases of the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are equilateral triangles with the same side lengths, and the side surfaces are isosceles triangles with the same side lengths.

[0059] Combine Figure 5 As shown, in another embodiment, the plurality of first tetrahedral protrusions 200 are all regular triangular pyramid structures, and the plurality of second tetrahedral protrusions 300 are all regular tetrahedral structures.

[0060] In the embodiment of the present disclosure, the first tetrahedral protrusion 200 is set to a regular triangular pyramid structure, and the second tetrahedral protrusion 300 is set to a regular tetrahedron structure. Since the base of the regular triangular pyramid structure is an equilateral triangle, the three side faces are isosceles triangles of the same size, and the four faces of the regular tetrahedron are all equilateral triangles, when the blade body 100 rotates, water splashes of different degrees are rolled up on the two side faces of the blade body 100, and a water film is better formed in the circumferential direction of the blade body 100.

[0061] Optionally, along the axial direction of the blade body 100, the height of the first tetrahedral protrusion 200 is greater than the height of the second tetrahedral protrusion 300. In this way, the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 with different structures are used to roll up water splashes on both sides of the blade body 100, while disturbing the water flow on both sides of the blade body 100, thereby better forming a water film in the circumferential direction of the blade body 100.

[0062] Combine Figure 6 As shown, in another embodiment, the plurality of first tetrahedral protrusions 200 and the plurality of second tetrahedral protrusions 300 are both regular tetrahedral structures.

[0063] In the embodiment of the present disclosure, since the four faces of the regular tetrahedron structure are all equilateral triangles, the first tetrahedron protrusion 200 and the second tetrahedron protrusion 300 are both set as regular tetrahedron structures, so that the shapes of the three sides of the first tetrahedron protrusion 200 and the second tetrahedron protrusion 300 in contact with water are more regular, thereby more evenly rolling up water splashes to form a water film in the circumferential direction of the blade body 100.

[0064] Optionally, the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are regular tetrahedral structures of the same size, so that the water splashes on both sides of the blade body 100 are more uniform, and the size and thickness of the water film formed in the circumferential direction of the blade body 100 are more uniform.

[0065] Combine Figure 7-11 As shown, in some embodiments, the first tetrahedral protrusion 200 includes a first side surface 210, a second side surface 220, a third side surface 230, and a fourth side surface 240, wherein the first side surface 210 is connected to a side wall of the blade body 100, and the second tetrahedral protrusion 300 includes a fifth side surface 310, a sixth side surface 320, a seventh side surface 330, and an eighth side surface 340, wherein the fifth side surface 310 is connected to another side wall of the blade body 100. In this way, the first side surface 210 of the first tetrahedral protrusion 200 is connected to a side wall of the blade body 100, and the fifth side surface 310 of the second tetrahedral protrusion 300 is connected to a side wall of the blade body 100, thereby increasing the connection area between the first tetrahedral protrusion 200, the second tetrahedral protrusion 300, and the side wall of the blade body 100, thereby improving the connection strength between the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 and the blade body 100.

[0066] Optionally, the first side 210 is the bottom surface of the first tetrahedral protrusion 200, the second side 220, the third side 230 and the fourth side 240 are the sides of the first tetrahedral protrusion 200, the fifth side 310 is the bottom surface of the second tetrahedral protrusion 300, and the sixth side 320, the seventh side 330 and the eighth side 340 are the sides of the second tetrahedral protrusion 300.

[0067] Specifically, when the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are both regular triangular pyramid structures, the first side 210 and the fifth side 310 are regular triangles, and the second side 220, the third side 230, the fourth side 240, the sixth side 320, the seventh side 330 and the eighth side 340 are all isosceles triangles.

[0068] Specifically, when the first tetrahedral protrusion 200 is a regular triangular pyramid structure and the second tetrahedral protrusion 300 is a regular tetrahedron structure, the first side surface 210, the fifth side surface 310, the sixth side surface 320, the seventh side surface 330 and the eighth side surface 340 are all regular triangles, and the second side surface 220, the third side surface 230 and the fourth side surface 240 are all isosceles triangles.

[0069] Specifically, when the first tetrahedral protrusion 200 and the second tetrahedral protrusion 300 are both regular tetrahedral structures, the first side 210, the second side 220, the third side 230, the fourth side 240, the fifth side 310, the sixth side 320, the seventh side 330 and the eighth side 340 are all equilateral triangles.

[0070] In a specific embodiment, the second side surface 220 , the third side surface 230 and the fourth side surface 240 are all concave surface structures that are recessed toward the interior of the first tetrahedral protrusion 200 .

[0071] In the embodiment of the present disclosure, since the first side surface 210 of the first tetrahedral protrusion 200 is connected to the side wall of the blade body 100, the second side surface 220, the third side surface 230, and the fourth side surface 240 are all in contact with water, the second side surface 220, the third side surface 230, and the fourth side surface 240 of the first tetrahedral protrusion 200 are all configured as concave surface structures. The second side surface 220, the third side surface 230, and the fourth side surface 240 can utilize their concave structures to store water. When the blade body 100 rotates, the second side surface 220, the third side surface 230, and the fourth side surface 240 can better scoop up water, so that the side of the blade body 100 provided with multiple first tetrahedral protrusions 200 can more efficiently roll up water splashes, better form a water film on the periphery of the blade body 100, and improve the water washing and humidification effect.

[0072] Optionally, the first side surface 210 , the fifth side surface 310 , the sixth side surface 320 , the seventh side surface 330 and the eighth side surface 340 are all planar structures.

[0074] In the embodiment of the present disclosure, since the fifth side surface 310 of the second tetrahedral protrusion 300 is connected to the side wall of the blade body 100, the sixth side surface 320, the seventh side surface 330, and the eighth side surface 340 are all in contact with water. Therefore, the sixth side surface 320, the seventh side surface 330, and the eighth side surface 340 of the second tetrahedral protrusion 300 are all configured as concave surface structures. The sixth side surface 320, the seventh side surface 330, and the eighth side surface 340 can utilize their concave structures to store water. When the blade body 100 rotates, the sixth side surface 320, the seventh side surface 330, and the eighth side surface 340 can better scoop up water, allowing the side of the blade body 100 provided with multiple second tetrahedral protrusions 300 to more efficiently roll up water spray. In conjunction with the multiple first tetrahedral protrusions 200, a better water film is formed on the periphery of the blade body 100, thereby improving the water washing and humidification effect.

[0075] Specifically, the first side surface 210 and the fifth side surface 310 are both planar structures, and the second side surface 220 , the third side surface 230 , the fourth side surface 240 , the sixth side surface 320 , the seventh side surface 330 and the eighth side surface 340 are all concave surface structures.

[0076] Combine Figure 12 As shown, in some embodiments, the water washing wheel includes: the water washing blades of any of the above embodiments.

[0077] By adopting the water washing wheel provided by the embodiment of the present disclosure and utilizing the water washing blades of any of the above embodiments, a water film can be better formed on the periphery of the water washing wheel, thereby improving the water washing and humidification effect.

[0078] Optionally, the water washing wheel comprises a plurality of water washing blades according to any of the above embodiments, and the plurality of water washing blades are evenly arranged along the axial direction, and adjacent water washing blades are detachably connected. In this way, the water washing wheel composed of the plurality of water washing blades can better roll up water splashes to form a water film when rotating.

[0079] Optionally, the water washing wheel further comprises a rotating shaft 400. The blade bodies 100 of the plurality of water washing blades are sequentially sleeved on the rotating shaft 400 along the axial direction. In this way, the plurality of water washing blades are mounted via the rotating shaft 400, and the plurality of water washing blades can be synchronously driven to rotate by driving the rotating shaft 400 to rotate.

[0080] Optionally, both ends of the rotating shaft 400 are provided with a driving gear 410, and the driving gear 410 is engaged with the output end of the driving motor 500. In this way, the rotating shaft 400 is driven to rotate by the driving motor 500, thereby synchronously driving the multiple washing blades to rotate.

[0081] Combine Figure 13 As shown, in some embodiments, the water washing device includes: the water washing wheel of the above embodiment.

[0082] By using the water washing device provided by the embodiment of the present disclosure, the water washing wheel of the above embodiment rotates to better roll up water splashes to form a water film on its periphery, thereby improving the water washing and humidification effect of the water washing device.

[0083] Optionally, the water washing device further includes a housing 600 and a fan 700. The housing 600 defines a water trough 610 and an air flow channel 620.
