[0002] As users pay more attention to indoor health issues, air conditioning health is the primary concern of users. Existing air inlets of air conditioners are generally equipped with filters to filter dust, particulate matter and other impurities, but the filtered air is not fresh and does not have the refreshing and slightly moist feeling of nature. For air conditioners with water washing function, the water washing module generally adopts the method of a water wheel plus a water tank. The water wheel rotates to throw out the water in the water tank. However, since the water wheel has a small range of water throwing, the contact range with the air is small, and the purification effect is poor.

[0003] The air purification module that can realize centrifugal water removal is composed of a pipe body and a rotating body with a screen. The water droplets that perform centrifugal motion form a water washing layer on the screen. After the air flows through the water washing layer, the high-speed moving water droplets combine with the particles or soluble substances in the air to purify the air. However, since the screen and the rotating body cannot be disassembled, the screen cannot be replaced and the overall replacement cost of the rotating body is high.

[0053] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0054] It should be noted that if there are directional indications (such as up, down, left, right, front, back, etc.) involved in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the meaning of "and / or" appearing in the full text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or solutions that satisfy both A and B.

[0055] The present invention provides an air purification module 100, which can be used alone or in combination with an air conditioner, specifically, the air conditioner can be a wall-mounted unit, an indoor unit of an air conditioner, or a mobile air conditioner, etc. The air purification module 100 can purify indoor air or fresh air by washing with water, so that the air flowing into the room is cleaner and can also achieve a humidification effect.

[0056] In the embodiment of the present invention, Figures 1 to 5 , Fig.10 and Fig.11As shown, the air purification module 100 includes:

[0057] A housing 1 having an air inlet 11, an air outlet 12, and a purification air duct 13 connecting the air inlet 11 and the air outlet 12; and

[0058] The rotating body 2 includes a bracket 21 and a screen 22 detachably mounted on the bracket 21. The rotating body 2 is rotatably disposed in the purification air duct 13. The rotating body 2 is suitable for throwing water outward by rotating when water is sprayed onto the screen 22.

[0059] In this embodiment, the shape of the shell 1 can be various, such as its cross-section can be circular, elliptical, rectangular, etc. In order to better cooperate with the air conditioner, the shape of the shell 1 can be set according to the specific model of the air conditioner used, and no special limitation is made here. The following embodiments are explained by taking the shell 1 as a cylindrical setting as an example. The shell 1 can be a structure with openings at both ends, with the openings at both ends serving as the air inlet 11 and the air outlet 12. The shell 1 can also be a structure with closed ends, with the air inlet 11 opened on one end of the shell 1 and the air outlet 12 opened on the other end. There can be various shapes of the air inlet 11 and the air outlet 12, such as circular, elliptical, square, polygonal, porous, etc., and no specific limitation is made here. The air inlet 11 includes a fresh air outlet, which is connected to the outside; and / or, an indoor air inlet 11, which is connected to the indoor. Since the rotating body 2 is wrapped by the shell 1 and then installed in the housing 200, the housing 1 can prevent the water thrown out by the rotating body 2 from flowing to the inner wall of the housing 200, thereby preventing other components on the inner wall of the housing 200 from being wetted and damaged. In addition, a plurality of air inlets 11 are provided and distributed at intervals along the circumference of the housing 1, so that air can enter from multiple circumferential positions, thereby better increasing the contact area with water.

[0060] In this embodiment, a screen 22 is arranged on the bracket 21. Due to the porous structure of the screen 22, it has good water viscosity, so the water droplets sprayed on the screen 22 are distributed more widely and more evenly, and the water droplets can reach the required particle size when rotating with the rotating body 2. When the rotating body 2 rotates at high speed, the screen 22 rotates at high speed with the rotating body 2, and the water sprayed on the screen 22 forms high-speed moving water droplets, which are distributed on the screen 22 and can be thrown outward with the screen 22. Then, the water droplets are fully contacted and mixed with the air flowing in from the air inlet 11, and the particulate matter, formaldehyde, etc. in the air are fully contacted with the water droplets and purified by water, so that the air can be effectively purified. In order to make the water droplet washing and filtering effect better and to capture PM2.5, optionally, the diameter of the water droplets distributed on the screen 22 is 30um-90um.

[0061] The bracket 21 provides support for the installation of the screen 22. The bracket 21 can be a solid disc-shaped structure. When the rotating body 2 is installed in the purification air duct 13, an air passage is formed between the rotating body 2 and the inner wall surface of the housing 1. When the water is cut into micro-droplets as the screen 22 rotates and thrown into the air passage, the particulate matter, formaldehyde, etc. in the air are fully in contact with the water droplets in the air passage and purified by the water. The bracket 21 can also be a shape of multiple radial ribs crossing, a ring structure, etc. The general shape of the bracket 21 can be circular, rectangular, special-shaped, etc., which is not specifically limited here, as long as it can provide support for the installation of the screen 22.

[0062] The screen 22 can be detachably mounted on the bracket 21 in a variety of ways, such as by screw or bolt connection, glue bonding, crimping connection, etc., and the specific connection method is not limited here. The screen 22 can be installed on the upper side of the bracket 21 or the lower side of the bracket 21. It can be understood that the screen 22 needs to be laid on the bracket 21 to have a large number of sticky water droplets. The material of the screen 22 can be plastic or metal. The shape of the screen 22 can be adapted and adjusted according to the shape of the housing 1 and the purification air duct 13, such as circular, rectangular, polygonal, etc.

[0063] Specifically, the air purification module 100 also includes a driving device 5 connected to the rotating body 2, and the output shaft of the driving device 5 is connected to the rotating body 2 to drive the rotating body 2 to rotate along its rotation axis. The driving device 5 is installed in the housing 1, and the driving device 5 is connected to the rotating body 2 to drive the rotating body 2 to rotate along its rotation axis. The driving device 5 is specifically a motor or other driving member that can drive the rotating body 2 to rotate. In practical applications, the outer edge linear velocity of the rotating body 2 is greater than or equal to 10 meters per second and less than or equal to 45 meters per second, preferably 20 meters per second to 30 meters per second. In this way, the water can be fully dispersed, effectively increasing the distribution amount of water droplets and water mist, and reducing the noise generated, thereby improving practicality.

[0064] The air purification module 100 of the present invention has a screen 22 installed on the bracket 21, so that the water sticking effect of the rotating body 2 is better. When water is sprayed on the screen 22, it is distributed more widely and more evenly. Then, when the screen 22 rotates at high speed with the rotating body 2, the water sprayed on the screen 22 forms high-speed moving water droplets, and the water droplets are fully contacted and mixed with the air flowing in from the air inlet 11. The particulate matter, formaldehyde, etc. in the air are purified by the water after being fully contacted with the water droplets, which can effectively purify the air; and the screen 22 is easy to be dirty and damaged after long-term use. The screen 22 is detachably installed on the bracket 21, and the screen 22 can be replaced, so that different screens 22 can be replaced and installed according to different needs, which is convenient for maintenance and replacement and improves practicality.

[0065] In one embodiment, please refer to Figure 7 and Figure 8 The bracket 21 is provided with a vent hole 211 for air to pass through the screen 22 .

[0066] In this embodiment, the ventilation holes 211 provided on the bracket 21 allow the bracket 21 to be ventilated. The shape of the ventilation holes 211 may be circular, rectangular, polygonal, or irregular, and the size and number of the ventilation holes 211 are not limited. It is sufficient that the screen 22 installed on the bracket 21 can be ventilated through the ventilation holes 211. The ventilation holes 211 may be holes provided on a solid structure, or holes formed by the structure of the bracket 21 itself. The bracket 21 may have a variety of shapes and structures. For example, the bracket 21 may be a structure formed by the intersection of multiple ribs, a spoke-shaped structure, a simple ring structure, a porous disc-shaped structure, etc. It is sufficient that there are ventilation holes 211 for air to pass through the screen 22, and no special limitation is made here. By providing the bracket 21 with ventilation holes 211, the airflow can pass through the screen 22 from the ventilation holes 211 of the bracket 21, thereby increasing the contact area between air and water, and the air can be fully mixed with a large number of water droplets distributed on the screen 22, thereby achieving a better water washing and filtration effect and a better purification effect. In order to fully mix the air with a large number of water droplets and obtain a better purification effect, the cross-sectional area of ​​the screen 22 is increased as much as possible while ensuring that the rotating body 2 and the screen 22 do not touch the housing 1 when rotating at high speed.

[0067] Furthermore, if Figures 3 to 7 As shown, the support 21 includes a rotating frame 212 and a pressing member 213 , and the screen 22 is disposed between the rotating frame 212 and the pressing member 213 .

[0068] In this embodiment, it is understood that the pressing member 213 fits with the end surface of the rotating frame 212 to press the screen 22 on the rotating frame 212. The rotating frame 212 and the pressing member 213 both have air holes 211 so that air can pass through the screen 22 from the bracket 21. The rotating frame 212 and the pressing member 213 can be arranged in an integral manner, or can be compressed and connected by welding, riveting, etc. In this case, a mounting groove can be opened on the rotating frame 212 and / or the pressing member 213 for the screen 22 to be inserted and installed. It is understood that only a small part of the screen 22 is used for compression connection, which will not affect the airflow of the screen 22. The pressing member 213 is used to fasten and press the screen 22 on the rotating frame 212 to prevent the screen 22 from falling off the rotating frame 212, thereby making the overall rotating body 2 more stable during the rotation process.

[0069] Furthermore, the rotating frame 212 is detachably connected to the pressing member 213. The rotating frame 212 and the pressing member 213 can be detachably connected by means of a clamping structure, a connecting column, a connecting member, bonding, etc. By making the rotating frame 212 and the pressing member 213 detachably connected, when replacing the screen 22, the screen 22 can be replaced by simply removing the pressing member 213 from the rotating frame 212, making the replacement more convenient and quick. And the pressing connection between the screen 22 and the pressing member 213 is more stable.

[0070] For further information, please refer to Figures 6 to 8 A connecting hole 30 is provided on the pressing member 213 , and a connecting column 10 fixedly matched with the connecting hole 30 is provided on the end surface of the rotating frame 212 .

[0071] In this embodiment, the number of the connecting holes 30 and the connecting posts 10 can be multiple and arranged at intervals along the circumferential direction. It is more convenient and quick to connect the rotating frame 212 and the pressing member 213 through the connecting holes 30 and the connecting posts 10, and the structure is simpler and easier to process. The matching of the connecting posts 10 and the connecting holes 30 can be a tight fit. In other embodiments, the connecting holes 30 can also be arranged on the rotating frame 212, and the connecting posts 10 can be arranged on the pressing member 213.

[0072] Further, in combination with the above-mentioned embodiment with the connecting hole 30 , the connecting column 10 passes through the screen 22 and is fixed in cooperation with the connecting hole 30 .

[0073] In this embodiment, it can be understood that a positioning hole is opened on the screen 22, so that the connecting column 10 passes through the screen 22 and is fixed to the connecting hole 30, which can prevent the circumferential movement and radial movement of the screen 22, thereby preventing the screen 22 from being misplaced or thrown out due to the excessive eccentricity generated by the rotating body 2.

[0074] Furthermore, if Figure 5 and Figure 7 As shown, the clamping member 213 includes an inner pressure ring 40 and an outer pressure ring 50 arranged outside the inner pressure ring 40 . The inner pressure ring 40 and the outer pressure ring 50 are arranged at an interval. Both the inner pressure ring 40 and the outer pressure ring 50 are pressed against the screen 22 .

[0075] In this embodiment, there may be no connection structure between the inner pressure ring 40 and the outer pressure ring 50, or they may be connected by connecting ribs. By dividing the clamping member 213 into the inner pressure ring 40 and the outer pressure ring 50, different parts of the screen 22 can be pressed and fixed, so that the force on each part of the screen 22 is more uniform, so that the crimping is more stable and the crimping effect is better. In addition, the gap between the inner pressure ring 40 and the outer pressure ring 50 can allow air to pass through a large area, reducing the windproof area of ​​the clamping member 213 on the screen 22, so that the contact area between the water droplets on the screen 22 and the air is larger, and the effect of water washing and filtration is better.

[0076] For further information, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 There are multiple supports 21 and screens 22 , each support 21 is provided with a screen 22 , and multiple supports 21 are stacked to form a water gap 23 between two adjacent screens 22 .

[0077] In this embodiment, a screen 22 can be provided on each bracket 21, so that a water gap 23 is formed between two adjacent screens 22, so that water has enough space to be arranged on the screen 22, and air has enough flow space on the single-layer screen 22, so that the water droplets on the screen 22 are in more sufficient contact with the air. If there are multiple brackets 21 and screens 22, the rotating body 2 has a multi-layer water washing structure, so that the air is in full contact with a large number of water droplets, so that the water washing filtration effect is better and the purification effect is better.

[0078] Furthermore, two adjacent brackets 21 are detachably connected. Two adjacent brackets 21 can be detachably connected by bolts, clamping, sleeve structures, etc. The detachable connection of two adjacent brackets 21 facilitates the installation and removal of a single bracket 21, and further facilitates the replacement of the screen 22. In other embodiments, multiple brackets 21 can also be connected in an integrated manner.

[0079] Please also refer to Figure 3 and Figure 4 Each bracket 21 includes a detachably connected rotating frame 212 and a pressing piece 213 , the screen 22 is arranged between the rotating frame 212 and the pressing piece 213 , and one rotating frame 212 of two adjacent rotating frames 212 is crimped to a pressing piece 213 and connected to the other rotating frame 212 .

[0080] In this embodiment, it can be understood that when two brackets 21 are arranged adjacent to each other, one rotating frame 212 can be used as a pressing piece of another rotating frame 212, and the two brackets 21 are pressed and connected to each other, and the pressing piece 213 is clamped, and no additional pressing piece is required, so that the overall structure is simpler and more compact, and the occupied space is reduced. The two rotating frames 212 can be connected by bolts or connected and fixed by their own structures, which is not specifically limited here.

[0081] Furthermore, a connecting hole 30 is provided on the clamping piece 213, and the rotating frame 212 has two oppositely arranged end faces, one of which is provided with a connecting column 10 passing through the connecting hole 30, and the other end face is provided with a crimping sleeve 20, and the crimping sleeve 20 of one rotating frame 212 is sleeved on the connecting column 10 of the other rotating frame 212.

[0082] In this embodiment, the structure of each rotating frame 212 can be set to be the same, which simplifies processing and installation. The crimping sleeve 20 and the connecting column 10 are detachably matched. By setting the crimping sleeve 20 to be connected to the connecting column 10, the matching method is simplified, making the overall structure simpler. When the connecting column 10 is connected to the crimping sleeve 20, a gap is formed between the two crimping sleeves 20, so that a sufficient gap is formed between the two screens 22.

[0083] Specifically, Figure 7 and Figure 8 As shown, there are multiple connecting posts 10, and the multiple connecting posts 10 are arranged at intervals along the circumference of the first rotating frame 212, and the number and position of the crimping sleeves 20 are arranged corresponding to the connecting posts 10. This makes the connection between the two adjacent rotating frames 212 more stable. In other embodiments, a connecting post 10 and a crimping sleeve 20 can be provided on one end surface of the rotating frame 212 at the same time. In this way, when the connecting post 10 on one end surface of the rotating frame 212 is damaged, the connection between the two adjacent rotating frames 212 can still remain stable.

[0084] Furthermore, if Figure 1 and Figure 6 As shown, the rotating body 2 also includes a connecting member 24, and the connecting member 24 is sequentially provided with a plurality of connecting rings, and the plurality of connecting rings are connected into one. The plurality of connecting rings are connected in series into one by the connecting member 24, so as to maintain the connection consistency of the entire rotating body 2 and make the connection of the plurality of connecting rings more stable. Specifically, the connecting member 24 is a connecting rib extending along the rotation axis of the rotating body 2. The connecting rib extends from one end of the rotating body 2 to the other end to connect all the plurality of brackets 21 together. In order to improve the connection stability, a plurality of connecting ribs are provided on the rotating body 2, and the plurality of connecting ribs are arranged at intervals along the circumference of the rotating body 2. By providing the connecting ribs, a better connection effect is achieved and the overall structure is also simpler.

[0085] For further information, please refer to Figure 1 , Figure 2 and Figure 5 The rotating body 2 further includes an upper fixing frame 25 and a lower fixing frame 26, a plurality of brackets 21 are disposed between the upper fixing frame 25 and the lower fixing frame 26, and a connecting member 24 connects the lower fixing frame 26, a plurality of connecting rings, and the upper fixing frame 25 in series. In this embodiment, the upper fixing frame 25 may have a similar structure to the rotating frame 212, and the upper fixing frame 25 and the lower fixing frame 26 together clamp the plurality of connecting rings, so that the connection of the plurality of rotating rings is more stable.

[0086] Furthermore, the lower fixing frame 26 is provided with a support rod 261, one end of which is connected to the housing 1. In this way, one end of the rotating body 2 is driven by the driving device 5 to rotate, while the other end of the rotating body 2 is limited by the support rod 261 to prevent the rotating body 2 from running off and shaking when rotating.

[0087] Furthermore, the mesh numbers of at least two sieves 22 are set differently. The sieves 22 with different mesh numbers can filter water droplets of different particle sizes, thereby filtering dust of different sizes, further improving the purification effect.

[0088] Furthermore, the mesh numbers of two adjacent screens 22 are set differently. In this way, the dust in the air is filtered layer by layer, thereby achieving a better purification effect.

[0089] Further, in the above embodiment in which the support 21 has a water-permeable hole, Figure 2 and Figure 5 As shown, the central areas of the plurality of brackets 21 and the plurality of screens 22 form a mounting channel 27 extending along the rotation axis of the rotating body 2 , and the gap between two adjacent screens 22 is connected to the mounting channel 27 .

[0090] In this embodiment, the water in the installation channel 27 is thrown out from the gap between the screens 22 and dispersed on the screens 22. The rotating body 2 rotates at a high speed, and the water thrown out of the installation channel 27 is distributed on the screen 22. Since the screen 22 can disperse the water droplets into the desired particle size, the water can also be thrown out from the tangent direction of the screen 22 into the purification duct 13. The air in the purification duct 13 can fully contact the water droplets on the screen 22 and the water droplets in the duct, and then the water droplets can capture and filter the particulate matter and air pollutants for effective purification.
