Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and particularly to a liquid breaking unit and an air treatment device including the liquid breaking unit. Background Art

[0002] In the prior art, there is an air treatment device that atomizes water, mixes it into the inhaled air, and then discharges it to the outside for humidification. As Figure 1 shown, an air humidifying purifier 1 as a prior air treatment device includes: a water tank 1-1 formed by a basin-shaped wall surface for storing water; a rotating shaft 1-2 longitudinally provided at the center of the top surface of the water tank 1-1; a water suction pipe 1-3 partially immersed in the water of the water tank 1-1 and connected to the rotating shaft 1-2 to rotate under the drive of the rotating shaft 1-2 to suck water from the water tank 1-1; a rotating motor 1-4 connected to the rotating shaft 1-2 to drive the rotating shaft 1-2 to rotate; and a water breaking part 1-5 provided on the outer side of the upper part of the water suction pipe 1-3 for atomizing the water droplets sucked up from the water suction pipe 1-3.

[0003] When the air humidifying purifier 1 operates, the rotational movement of the rotating motor 1-4 is transmitted to the water suction pipe 1-3 through the rotating shaft 1-2 to make the water suction pipe 1-3 rotate. Under the action of the centrifugal force generated by the rotation, the water suction pipe 1-3 sucks water upward from the water tank 1-1. Specifically, the water in the water tank 1-1 is sucked from the water suction port 1-6 at the lower end of the water suction pipe 1-3 along the inner wall of the water suction pipe 1-3 to the upper part of the water suction pipe 1-3, and then detaches from the upper part of the water suction pipe 1-3 and flies out in the centrifugal direction. The water droplets flying out at high speed from the upper part of the water suction pipe 1-3 are further broken after hitting the water breaking part 1-5. Thus, the water droplets are broken into finer water mist, mixed with the air flow entering the inside of the air humidifying purifier 1 and located around the water breaking part 1-5, and then discharged from the air humidifying purifier 1 to achieve humidification.

[0004] On the one hand, when the water suction pipe 1-3 rotates rapidly, the water in the water tank 1-1 is sucked into the water suction pipe 1-3 from the water suction port 1-6 at the lower end of the water suction pipe 1-3. At this time, the water level around the water suction pipe 1-3 decreases, resulting in a reduction in the rotational resistance of the water around the water suction pipe 1-3 to the water suction pipe 1-3, and the load of the rotation motor 1-4 decreases accordingly. When the torque of the rotation motor 1-4 is constant, when the load of the rotation motor 1-4 decreases, the rotational speed of the rotation motor 1-4 increases. On the other hand, the water around the water suction pipe 1-3 immersed in the water tank 1-1 flows outward along the longitudinal side wall of the water tank 1-1 under the drive of the centrifugal force of the rotating water suction pipe 1-3 until it collides with the longitudinal side wall of the water tank 1-1 and then rebounds back to the periphery of the water suction pipe 1-3, causing the water level around the water suction pipe 1-3 to rise again. As a result, the load of the rotation motor 1-4 increases and the rotational speed of the rotation motor 1-4 decreases. In this way, due to the unstable rotational speed of the rotation motor 1-4, the water in the water tank 1-1 forms continuous reciprocating waves, and the waves hitting the components of the device will generate noise. Moreover, due to the unstable rotational speed of the rotation motor 1-4, the amount of water sucked by the water suction pipe 1-3 changes continuously, resulting in unstable humidification amount of the air humidifying purifier 1.

[0005] To solve the above problems, the present invention provides a liquid breaking unit that can suppress unstable humidification amount and noise, and an air treatment device including the liquid breaking unit. Summary of the Invention

[0020] According to one embodiment, each of the first water lifting plate and the plurality of second water lifting plates includes: a water lifting plate curved surface, which is closely attached to the outer wall of the water suction pipe and is formed into a curved surface that slopes radially outward and upward; and a water lifting plate flat surface, which is a horizontal plane extending radially outward from the water lifting plate curved surface.

[0021] According to one embodiment, the upper end of the fine water spraying hole is flush with or lower than the upper side surface of the water lifting plate flat surface, and the lower end of the fine water spraying hole is closely located above the upper side surface of the water lifting plate curved surface that is closely attached to the water suction pipe.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The following will describe in detail a liquid breaking unit according to the present invention and an air treatment device including the liquid breaking unit with reference to the accompanying drawings.

[0052] Figure 2 is a schematic structural view of an air treatment device according to the present invention. Specifically, Figure 2 is a front view of an air treatment device 10 according to the present invention. Figure 3 is along Figure 2 a cross-sectional view taken along A-A' in, specifically a vertical cross-sectional view of the air treatment device 10. The air treatment device 10 according to the present invention is a general household air humidification device, usually placed in a storage space such as above the ceiling or below the ground where users cannot directly observe, and is connected to a ventilation duct to humidify and adjust indoor and outdoor air in each household space. In addition, the air treatment device 10 may also include functions such as dehumidifying, ventilating, disinfecting, or heat exchanging the air.

[0053] The air treatment device 10 includes a housing 11.

[0054] The housing 11 forms the outer shell of the air treatment device 10 and is a three-dimensional box-shaped structure surrounded by six faces. Specifically, the housing 11 is formed as a cuboid structure formed by six planes and internally forms a space for accommodating at least one functional unit for realizing air treatment functions. The at least one functional unit includes a liquid breaking unit described below. An air suction port 12 and an air discharge port 14 are provided on the housing 11.

[0055] The air suction port 12 is an opening provided on the housing 11, which is located on one of the six faces forming the housing 11 and is used to allow the air outside the housing 11 to enter the interior of the housing 11. As Figure 2 shown, the housing 11 according to the present invention is provided with one air suction port 12, which is located on the left side face of the housing 11 as shown in the figure.

[0056] The air discharge port 14 is an opening provided on the housing 11, which is located on the side face of the housing 11 opposite to the air suction port 12 among the six faces forming the housing 11 and is used to allow the air inside the housing 11 to be discharged to the outside of the housing 11. As Figure 2As shown, the housing 11 according to the present invention is provided with eight air outlets 14, which are located on the right side surface of the housing 11 as shown in the figure. The eight air outlets 14 are arranged in two rows vertically, with four in each row. The number, positional relationship, and layout structure of the air inlets 12 and air outlets 14 are not limited to this, and can be designed and adjusted according to needs.

[0057] The liquid fragmentation unit 100 is provided inside the housing 11 of the air treatment device 10, and forms an air flow connection with the air inlet 12 and the air outlet 14, that is, the air outside the housing 11 is discharged outside the housing 11 through the air inlet 12, the liquid fragmentation unit 100, and the air outlet 14 in sequence. As Figure 3 shown, when the air inlet 12 and the air outlet 14 are respectively arranged on the left side surface and the right side surface of the housing 11, the liquid fragmentation unit 100 is arranged between the air inlet 12 and the air outlet 14, so that the air inlet 12, the liquid fragmentation unit 100, and the air outlet 14 form an air flow path. The liquid fragmentation unit 100 is used to fragment a liquid (such as water) to make it micronized, and mix the micronized liquid with the air passing through the liquid fragmentation unit 100, thereby increasing the humidity of the air after passing through the liquid fragmentation unit 100. The air mixed with the micronized liquid is then discharged outside the air treatment device 10, achieving the effect of increasing the air humidity in the space.

[0058] In the present invention, the air supply unit (not shown in the figure) for driving the air flow is provided outside the air treatment device 10 in the form of an independent device, that is, it is connected to the air inlet 12 through a pipeline and is located on the upstream side of the air treatment device 10; and / or is connected to the air outlet 14 through a pipeline and is located on the downstream side of the air treatment device 10. In the common technology in this field, the air supply unit can also be arranged inside the air treatment device 10, and this can be designed and adjusted according to needs.

[0059] Referring to Figure 3 shown, a wind guiding structure 300 can also be arranged inside the housing 11. The wind guiding structure 300 is arranged between the air inlet 12 and the liquid fragmentation unit 100. When the wind guiding structure 300 works, it can suck air from the outside of the housing 11 through the air inlet 12, and then transport the sucked air to the liquid fragmentation unit 100 to perform the above-mentioned liquid fragmentation function. However, the present invention is not limited to this.

[0060] Figure 4 is a schematic structural view of the liquid fragmentation unit according to the present invention. Specifically, it is a top view of the liquid fragmentation unit observed from an inclined upper direction. Figure 5 is along Figure 4 the cross-sectional view of D-D' in Figure 4 and Figure 5, the liquid breaking unit 100 includes: a water storage part 200, a breaking part 400, a driving part 600, and a water blocking part 800. Figure 4 and Figure 5 shows the installation and positional relationship among the water storage part 200, the breaking part 400, the driving part 600, and the water blocking part 800 in the liquid breaking unit 100.

[0061] Figure 6 is Figure 5 a schematic structural view of the water storage part shown, specifically, a top view of the water storage part 200 observed from an inclined upper side. Hereinafter, reference will be made to Figures 4 to 6 describe the water storage part 200 in detail.

[0062] The water storage part 200 is used to store the liquid for humidifying the air. The water storage part 200 includes: a water storage part bottom surface 210, a water storage part side surface 220, a water storage part opening 230, a water storage recessed part 240, and a liquid storage space 270 formed by the water storage part bottom surface 210 and the water storage part side surface 220.

[0063] The water storage part bottom surface 210 is the bottom surface located at the lower end of the water storage part 200 relative to the vertical direction. The water storage part bottom surface 210 slopes downward from the water storage part side surface 220 described below toward the water storage recessed part direction 240 described below in the vertical direction. That is, the lowest point is provided on the water storage part bottom surface 210, and the water storage recessed part 240 is provided at the lowest point position of the water storage part bottom surface 210. Thus, the liquid stored in the water storage part 200 can gather toward the water storage recessed part 240 along the inclined direction of the water storage part bottom surface 210.

[0064] The water storage part side surface 220 is a side wall surface extending vertically upward from the outer edge of the water storage part bottom surface 210. The water storage part side surface 220 and the water storage part bottom surface 210 form a liquid storage space 270 that can accommodate the liquid.

[0065] The water storage part opening 230 is located on the opposite side of the water storage part bottom surface and is an opening surrounded by the upper edge of the water storage part side surface 220.

[0066] The water storage recessed part 240 is a recessed space formed by vertically downward recessing from the water storage part bottom surface 210. According to an embodiment of the present invention, as described above, the water storage part bottom surface 210 slopes downward from the water storage part side surface 220 toward the water storage recessed part 240, and the water storage recessed part 240 recesses in the vertical direction away from the water storage part opening 230. In this embodiment, the water storage recessed part 240 is in the shape of an inverted frustum, that is, it includes: a water storage recessed part top surface 241, a water storage recessed part bottom surface 242, and a water storage recessed part side surface 243.

[0067] The top surface 241 of the water storage recessed portion is the top surface facing the water storage opening 230 and is the top surface where the water storage recessed portion 240 is recessed longitudinally downward from the bottom surface 210 of the water storage portion. When viewed from above longitudinally, the top surface 241 of the water storage recessed portion is circular. A drain port 250 is provided on the water storage recessed portion 240.

[0068] The drain port 250 is a hole provided on the top surface 241 of the water storage recessed portion, that is, it is located at the lowest position of the water storage recessed portion 240. In this way, after the air humidification operation stops, the liquid accumulated in the water storage portion 200 can gather along the bottom surface 210 of the water storage portion towards the water storage recessed portion 240, reach the water storage recessed portion 240, and then be discharged to the outside of the liquid breaking unit 100 through the drain port 250.

[0069] The bottom surface 242 of the water storage recessed portion is an invisible surface (represented by a dotted line in the figure) facing the water storage portion opening 230 and located longitudinally above the top surface 241 of the water storage recessed portion. That is to say, the bottom surface 242 of the water storage recessed portion is the missing surface of the bottom surface 210 of the water storage portion. When viewed from above longitudinally, the bottom surface 242 of the water storage recessed portion is circular, and the area of the bottom surface 242 of the water storage recessed portion is larger than the area of the top surface 241 of the water storage recessed portion. Thus, the water storage recessed portion 240 is formed in a frustum shape with a larger top and a smaller bottom.

[0070] The side surface 243 of the water storage recessed portion is an inclined surrounding side surface in a frustum shape with a larger top and a smaller bottom, sandwiched between the bottom surface 242 and the top surface 241 of the water storage recessed portion. In this embodiment, the included angle between the side surface 243 of the water storage recessed portion and the top surface 241 of the water storage recessed portion is 135°.

[0071] It should be noted that the liquid stored in the water storage portion 200 can be water or other liquids, as long as it has a humidifying effect. Generally, the liquid is provided to the water storage portion 200 through a water supply portion (not shown in the figure) located above the water storage portion 200 or on the side surface 220 of the water storage portion. The water supply portion directly supplies water to the water storage portion 200 through a connecting water supply pipe (for example, from a tap water pipe).

[0072] As Figure 4 and Figure 5 shown, the water suction pipe 410 of the breaking portion 400 is provided at the position of the water storage recessed portion 240, and a water blocking portion 800 is sleeved near the lower end of the water suction pipe 410. Therefore, a water blocking portion installation structure 260 for installing the water blocking portion 800 is provided on the bottom surface 210 of the water storage portion around the water storage recessed portion 240.

[0073] Next, refer to Figure 7 and Figure 8 to describe the breaking portion in detail. Figure 7 is Figure 4 a schematic structural view of the liquid breaking unit according to the present invention with the water blocking portion removed. Specifically, it is Figure 4The top view of the liquid breaking unit according to the present invention shown, as viewed obliquely from above, with the water blocking part removed. Figure 8 is a cross-sectional view taken along Figure 7 B - B' in [description], specifically, is Figure 4 a vertical cross-sectional view of the structure shown.

[0074] The breaking part 400 is used to micronize the liquid stored in the water storage part 200, making it easier for the liquid particles to be mixed in the air and then discharged. The breaking part 400 is provided above the bottom surface 210 of the water storage part, that is, a lower part of the breaking part 400 is located in the liquid storage space 270 of the water storage part 200 and an upper part is located above the liquid storage space 270 of the water storage part 200. The breaking part 400 includes a water suction pipe 410, a first water lifting plate 420, and a second water lifting plate 430.

[0075] The water suction pipe 410 passes through the opening 230 of the water storage part and its lower end is inserted into the liquid in the liquid storage space 270 of the water storage part 200, and is located directly above the water storage depression part 240. As Figure 8 shown, the lower end of the water suction pipe 410 is located in the water storage depression part 240, that is, the lower end of the water suction pipe 410 is lower than the bottom surface 210 of the water storage part, and there is a gap between the lower end of the water suction pipe 410 and the bottom surface of the water storage depression part 240. The water suction pipe 410 is a hollow tubular structure with openings at both the upper end and the lower end. In this embodiment, the water suction pipe 410 is an overall hollow structure in the shape of an inverted frustum, and sucks the liquid stored in the water storage part 200 into the hollow space by high-speed rotation. The water suction pipe 410 can also be set as a hollow structure of other shapes, such as an inverted horn shape or an inverted stepped shape, etc. When a certain amount of liquid is stored in the water storage part 200, the lower part of the water suction pipe 410 is immersed in the liquid. In this embodiment, when the liquid breaking unit 100 operates normally, the height from the liquid surface to the top surface 241 of the water storage depression part is generally controlled between 26.1 mm and 28.75 mm, and its height can be adjusted accordingly according to the water absorption demand, etc. The water suction pipe 410 includes a water suction port 412, a water spraying port 413, a barrel wall 411, and fine water spraying holes 414.

[0076] The water suction port 412 is an opening provided at the lower end of the water suction pipe 410, which is used to suck the liquid in the water storage part 200 into the inverted frustum-shaped hollow space. The water suction port 412 is located within the recessed space of the water storage recess 240. That is to say, the water suction port 412 faces the water storage recess, the water suction port 412 is lower than the bottom surface 210 of the water storage part and does not contact the top surface 241 of the water storage recess, that is, it is spaced apart from the top surface 241 of the water storage recess, and is longitudinally located between the top surface 241 and the bottom surface 242 of the water storage recess. In addition, the drain port 250 of the water storage recess 240 is opposite to the water suction port 412 and is located at the center of the top surface 241 of the water storage recess. In this embodiment, the distance between the water suction port 412 and the top surface 241 of the water storage recess is 2 mm. Through the water suction port 412, the liquid in the water storage recess 240 can be sucked into the hollow space of the water suction pipe 410 from the water suction port 412 of the water suction pipe 410.

[0077] The water spray port 413 is an opening provided at the upper end of the water suction pipe 410, that is, the water spray port 413 is arranged opposite to the water suction port 412, and is used for the liquid inside the water suction pipe 410 to be sprayed out to the outside of the water suction pipe 410. It should be noted that the opposite arrangement here means that the plane where the water spray port 413 is located is parallel to the plane where the water suction port 412 is located, and the projection of the water spray port 413 in the direction of the water suction port 412 coincides with at least a part of the water suction port 412, that is, the projection of the water spray port 413 on the plane where the water suction port 412 is located coincides with at least a part of the water suction port 412. When the water suction pipe 410 is designed as an inverted frustum-shaped structure, the diameter of the water spray port 413 is larger than the diameter of the water suction port 412. In this embodiment, the projections of the water spray port 413 and the water suction port 412 in the vertical direction are concentric circles.

[0078] The barrel wall 411 is an enclosing wall of the water suction pipe 410 that extends basically in the vertical direction, that is, a continuous wall surface connecting the outer peripheral edge of the water suction port 412 and the outer peripheral edge of the water spray port 413. In this embodiment, since the water suction pipe 410 is set in an inverted frustum shape, the barrel wall 411 is set as the side surface of the inverted frustum-shaped structure. The horizontal cross-sections of the barrel wall 411 at different vertical heights are concentric and different-sized circular ring shapes, and the circular ring shape of the horizontal cross-section gradually becomes larger from the water suction port 412 to the water spray port 413. According to an embodiment of the present invention, a plurality of water-lifting ribs 417 are provided on the inner wall of the barrel wall 411 at the position of the water suction port 412.

[0079] The water-lifting rib 417 is a plate-like structure that radially protrudes from the inner wall of the barrel wall 411 towards the central axis direction of the water suction pipe 410. The water-lifting rib 417 extends along the axial direction of the water suction pipe 410. A plurality of water-lifting ribs 417 are evenly distributed along the circumferential direction of the inner wall of the barrel wall 411. The water-lifting rib 417 can make the liquid be sucked upward more easily. The water-lifting rib 417 can also be set as a spiral shape along the inner wall of the barrel wall 411 or a dot-like or block-like structure protruding from the inner wall of the barrel wall 411, etc.

[0080] A plurality of fine water spray holes 414 are formed in the cylindrical wall 411 below the water spray port 413. The fine water spray holes 414 are small openings provided in the cylindrical wall 411 and passing through the cylindrical wall 411. The liquid sucked into the hollow space of the water suction pipe 410 from the water suction port 412 is ejected from the fine water spray holes 414 to the outer peripheral side of the water suction pipe 410 under the action of the rotational centrifugal force of the water suction pipe 410. The fine water spray holes 414 are provided near the upper end of the water suction pipe 410, that is, at a position below the water spray port 413 on the cylindrical wall 411. In this embodiment, the fine water spray holes 414 are slits extending in the circumferential direction of the cylindrical wall 411. That is to say, when the cylindrical wall 411 is unfolded into a plane, the fine water spray holes 414 are rectangular or elliptical. The fine water spray holes 414 can be divided into a plurality of groups arranged vertically, and the fine water spray holes 414 in each group can be evenly distributed in the circumferential direction of the cylindrical wall 411. For example, in this embodiment, a total of six fine water spray holes 414 are provided and divided into three groups, each group including two fine water spray holes 414. The two fine water spray holes 414 in each group are arranged opposite to each other, and each group of fine water spray holes is provided at different vertical heights.

[0081] The crushing part 400 further includes a first water lifting plate 420 and a plurality of second water lifting plates 430. The first water lifting plate 420 and the second water lifting plates 430 are plate-like structures arranged substantially horizontally near the upper end position of the water suction pipe 410, and are used to further accelerate the liquid discharged from the fine water spray holes 414, so that it adheres to the surfaces of the first water lifting plate 420 and the second water lifting plates 430 and moves in the centrifugal direction, and finally is thrown off the first water lifting plate 420 and the second water lifting plates 430 to be further refined. Specifically, the first water lifting plate 420 and the second water lifting plates 430 protrude from the outer wall of the cylindrical wall 411 of the water suction pipe 410 to the outside away from the water suction pipe 410, and are arranged in a substantially horizontal circular ring flat plate shape. The first water lifting plate 420 extends radially outward horizontally from the edge of the water spray port 413 to form a circular plate shape, and the plurality of second water lifting plates 430 are similar in shape to the first water lifting plate 420, that is, substantially in a circular ring plate shape, and are arranged parallel to and spaced apart from each other below the first water lifting plate 420. There is a certain interval between two adjacent water lifting plates among the first water lifting plate 420 and the second water lifting plates 430, and this interval corresponds to the interval in the vertical direction of the above-mentioned divided fine water spray hole groups. A plurality of fine water spray holes 414 are provided between two adjacent water lifting plates. Specifically, the plurality of fine water spray holes 414 provided between two adjacent water lifting plates correspond to the above-mentioned divided fine water spray hole groups, and the plurality of fine water spray holes 414 in this fine water spray hole group are evenly arranged in the circumferential direction between two adjacent water lifting plates. As described above, when each group of fine water spray hole groups includes two fine water spray holes 414, the two fine water spray holes 414 are arranged opposite to each other between two adjacent water lifting plates.

[0082] In this embodiment, the first water-lifting plate 420 is integrally formed with the cylinder wall 411, and a plurality of second water-lifting plates 430 are detachably connected to the adjacent water-lifting plate above. For example, when three second water-lifting plates 430 are provided, the uppermost second water-lifting plate 430 among the three second water-lifting plates 430 is detachably connected to the first water-lifting plate 420, the middle second water-lifting plate 430 among the three second water-lifting plates 430 is detachably connected to the uppermost second water-lifting plate 430, and the lowermost second water-lifting plate 430 among the three second water-lifting plates 430 is detachably connected to the middle second water-lifting plate. The connection manner can be realized by adopting a fitting structure or other common technical solutions in the art on two adjacent water-lifting plates. The second water-lifting plate 430 can also be integrally formed with the cylinder wall 411.

[0083] In this embodiment, when six fine water spray holes 414 are provided as described above and divided into three groups of fine water spray hole groups, the number of the second water-lifting plates 430 is three, and the first water-lifting plate 420 and the three second water-lifting plates 430 are arranged at intervals in the vertical direction, forming three intervals, and the three groups of fine water spray hole groups divided are respectively arranged in the three intervals. In an embodiment according to the present invention, the first water-lifting plate 420 and a plurality of second water-lifting plates 430 are arranged in a horizontal circular ring coaxial with the water suction pipe 410. In this embodiment, the first water-lifting plate 420 and a plurality of second water-lifting plates 430 are set to have the same size, but in other embodiments, they can also be set to be different from each other, which can be designed according to the required degree of fragmentation. According to an embodiment of the present invention, each of the first water-lifting plate 420 and a plurality of second water-lifting plates 430 includes a water-lifting plate curved surface 415 and a water-lifting plate flat surface 416.

[0084] The water-lifting plate curved surface 415 closely adheres to the outer wall of the cylinder wall 411 of the water suction pipe 410 and is formed into a curved surface that slopes radially outward and upward. That is to say, the water-lifting plate curved surface 415 is located at the end close to the water suction pipe 410 side. The upper side of the water-lifting plate curved surface 415 that closely adheres to the outer wall of the cylinder wall 411 is closely adhered below the lower end of the corresponding fine water spray hole 414, that is, the upper side of the inner peripheral side end of the water-lifting plate curved surface 415 is closely adhered below the corresponding fine water spray hole 414.

[0085] The water-lifting plate flat surface 416 is a horizontal plane extending radially in the centrifugal direction away from the water suction pipe 410 from the water-lifting plate curved surface 145. The upper side of the water-lifting plate flat surface 146 is set to be higher than or equal to the upper end of the corresponding fine water spray hole 414.

[0086] Thus, the liquid ejected from the micro water spray holes 414 can first stay briefly on the curved surface 415 of the water lifting plate. The curved surface design of the water lifting plate curved surface 415 can prevent the ejected liquid from being directly thrown out along the centrifugal direction and thus cannot be further accelerated and miniaturized. The liquid staying briefly on the micro water spray holes 414 can continue to move towards the water lifting plate plane 416 under the action of centrifugal force, and is further miniaturized after being accelerated by the water lifting plate plane 416.

[0087] The following will refer to Figure 7 and Figure 8 to describe the drive unit 600 in detail.

[0088] The drive unit 600 is connected to the crushing unit 400 and drives the suction pipe 410 to rotate. The drive unit 600 is provided above the crushing unit 400. According to an embodiment of the present invention, the drive unit 600 includes a motor 610, a rotating shaft 620, and a rotating plate 630.

[0089] The motor 610 is a DC brushless motor commonly used in the art, and drives the rotating shaft 620 connected thereto to rotate after being connected to a power source and powered on.

[0090] The rotating shaft 620 is driven by the motor 610 to rotate, extends from inside the motor 610 downward, and is used to connect the motor 610 and the crushing unit 400, thereby driving the crushing unit 400 to operate. Specifically, it drives the suction pipe 410 to rotate, so that the suction pipe 410 sucks liquid.

[0091] The rotating plate 630 is arranged on the rotating shaft 620 and has a shape similar to that of the first water lifting plate 420, and is arranged between the motor rotating shaft 620 and the first water lifting plate 420. The rotating plate 630 is used to connect the rotating shaft and the first water lifting plate 420, so as to transmit the rotation of the rotating shaft 620 to the first water lifting plate 420, and then further transmit it to the suction pipe 410. Similar to the connection method between the above-mentioned first water lifting plate 420 and the plurality of second water lifting plates 430, the connection method between the rotating plate 630 and the first water lifting plate 420 can be realized by mutual fitting structures and other common technical solutions in the art. In this embodiment, the rotating plate 630 and the first water lifting plate 420 are connected in parallel and spaced apart from each other. The shape of the rotating plate 630 is approximately circular ring-shaped similar to the water lifting plate, and the diameter length of the rotating plate 630 is the same as that of the first water lifting plate 420. When observed vertically from above, the rotating plate 630 covers the first water lifting plate 420 and the second water lifting plate 430; in addition, the combination of the rotating plate 630 and the rotating shaft 620 covers the water spray port 413 of the suction pipe 410.

[0092] The following will refer to Figure 4 and Figures 9 to 12 to describe the water blocking unit 800 in detail. Figure 9 For Figure 4Schematic structural view of the water retaining part of the liquid breaking unit according to the present invention, specifically, a top view of the water retaining part observed from an inclined upper side. Figure 10 is Figure 9 Schematic structural view of the water retaining part observed from an inclined lower side. Figure 11 is Figure 9 Top view of the water retaining part shown. Figure 12 is a sectional view along Figure 9 C-C' in

[0093] The water retaining part 800 is used to resist the liquid surge caused by the rotation of the water suction pipe 410, which makes the liquid around the water suction pipe 410 surge outward. In other words, when the breaking part 400 works, a surge that diffuses outward from the water suction pipe 410 may be generated. The water retaining part 800 can resist the continuous outward diffusion of the surge and at the same time suppress the change in the height of the liquid surface (i.e., the depth of the liquid). In the vertical direction, the water retaining part 800 is arranged between the bottom surface 210 of the water storage part and the second water lifting plate 430, and at the same time, part of it is located in the liquid storage space 270 surrounded by the water storage part 200. The water retaining part 800 is sleeved near the lower end of the water suction pipe 410 and is spaced apart from the water suction pipe 410. That is to say, the water retaining part 800 surrounds the lower end of the water suction pipe 410. The water retaining part 800 includes a water retaining surface 810 and water retaining ribs 820.

[0094] The water-blocking surface 810 is formed as a closed surface facing the water suction pipe 410 and surrounding the water suction pipe 410, particularly a closed circumferential surface. In this embodiment, the water-blocking surface 810 extends in the vertical direction, and when viewed from the vertical direction, the water-blocking surface 810 has a circular perimeter shape, which is the same as the horizontal cross-sectional shape of the water suction pipe 410 and the horizontal cross-section of the water-blocking surface 810 and the horizontal cross-section of the water suction pipe 410 are concentric circles. The water-blocking surface 810 can also be arranged to extend obliquely in the vertical direction as long as it is a surface that can resist the surging flow. In this embodiment, the water storage recess 240 is surrounded by the surface where the water-blocking surface 810 is located at intervals, that is, when viewed from the vertical direction, the water-blocking surface 810 is located outside the bottom surface 242 of the water storage recess, the water-blocking surface 810 surrounds the water storage recess 240, and there is a distance between the water-blocking surface 810 and the bottom surface 242 of the water storage recess. The water-blocking surface 810 faces the water suction pipe 410, and the lower side edge of the water-blocking surface 810 is close to the bottom surface 210 of the water storage part but does not contact each other, that is, there is a gap between the lower side edge of the water-blocking surface 810 and the bottom surface 210 of the water storage part, and this gap is called the water-blocking surface gap 811 in the present invention. The water-blocking surface gap 811 can allow the liquid outside the water-blocking part 800 to flow into the water-blocking part 800 through this gap, so as to be sucked by the water suction pipe 410, ensure the stability of the liquid level inside the waterproof part 800, and when the liquid breaking action is completed, the liquid outside the water-blocking part 800 can also flow into the water storage recess 240 through this gap to be discharged from the drain port 250. According to an embodiment of the present invention, in order to conveniently fix the water-blocking surface 810 on the water storage part 200 and strengthen the strength of the water-blocking surface 810, the water-blocking part 800 further includes a water-blocking part top surface 830, a water-blocking part outer peripheral surface 840, and a water-blocking part reinforcing rib 850.

[0095] The water-blocking part top surface 830 is formed by extending perpendicularly outward from the upper side edge of the water-blocking surface 810. The water-blocking part top surface 830 faces vertically upward and has an annular shape.

[0096] The outer peripheral surface 840 of the water retaining part extends vertically downward from the outer side edge of the top surface 830 of the water retaining part, that is, the outer peripheral surface 840 of the water retaining part faces the water retaining surface 810 and there is a gap therebetween. The outer peripheral surface 840 of the water retaining part is provided with a water retaining part fixing part 870 extending outward to the outer peripheral side. In this embodiment, the water retaining part fixing part 870 is in the shape of an annular plate extending horizontally outward perpendicular to the outer peripheral surface 840 of the water retaining part. A lug 860 is provided on the fixing part 870, and a screw hole for inserting a screw is provided on the lug 860. The screw hole cooperates with the water retaining part mounting structure 260 provided on the bottom surface 210 of the water storage part. Based on this, the water retaining part mounting structure 260 is set as a corresponding columnar screw bolt. The user can fix the water retaining part 800 to the water storage part 200 by fixing the screw hole and the screw bolt with screws. The outer peripheral surface 840 of the water retaining part is similar to the water retaining surface 810 and there is a gap between it and the bottom surface 210 of the water storage part. Similar to the function of the water retaining surface gap 811, this gap can allow the liquid outside the water retaining part 800 to flow into the water retaining part 800 through this gap, so as to be sucked by the suction pipe 410, ensuring the stable liquid level inside the waterproof part 800. And when the liquid breaking action ends, the liquid outside the water retaining part 800 can also flow into the water storage recess 240 through this gap to be discharged from the drain port 250.

[0097] The water retaining part reinforcing rib 850 is arranged in the gap between the outer peripheral surface 840 of the water retaining part and the water retaining surface 810, and is formed as a rib-like structure connecting the outer peripheral surface 840 of the water retaining part and the water retaining surface 810, serving to strengthen the strength of the water retaining part 800.

[0098] The water retaining rib 820 protrudes from the water retaining surface 810 in the direction of the suction pipe 410 and slopes downward along the rotation direction of the suction pipe 410. The water retaining rib 820 can be used to guide the liquid surge blocked by the water retaining surface 810 to flow downward, thereby suppressing the change in the depth of the liquid. In this embodiment, a plurality of water retaining ribs 820 are provided and are evenly arranged along the circumferential direction of the water retaining surface 810. For example, four water retaining ribs 820 can be provided, and every two are arranged opposite to each other in a group, and the four water retaining ribs 820 are evenly distributed on the water retaining surface 810 in the horizontal plane. The projections of the plurality of water retaining ribs 820 in the vertical direction are staggered from each other. For example, the projections of the four water retaining ribs 820 in the vertical direction are staggered, that is, the projections do not overlap each other (as Figure 11 shown). In other words, the four water retaining ribs 820 are spaced apart from each other and do not overlap on the horizontal plane. The water retaining rib 820 is set as a sheet-like structure and includes a water retaining rib upper edge 823, a water retaining rib lower edge 824, a water retaining rib inner peripheral side edge 825, a water retaining rib upper side surface 821, and a water retaining rib lower side surface 822.

[0099] The upper edge 823 of the water retaining rib is an edge that protrudes from the water retaining surface 810 and the water retaining rib 820 is located at the upper side position in the vertical direction. The upper edge 823 of the water retaining rib is a straight edge, that is, a straight line parallel to the radius of the water retaining surface 810.

[0100] The lower edge 824 of the water retaining rib is an edge that protrudes from the water retaining surface 810 and is located at the lower side position in the vertical direction of the water retaining rib 820. The lower edge 824 of the water retaining rib is a straight edge parallel to the upper edge 823 of the water retaining rib. There is a gap between the lower edge 824 of the water retaining rib and the lower side edge of the water retaining surface 810, and this gap is called the water retaining rib gap 826 here.

[0101] The inner peripheral side edge 825 of the water retaining rib is an edge formed by connecting the top end of the upper edge 823 of the water retaining rib and the top end of the lower edge 824 of the water retaining rib, and is the edge of the water retaining rib 820 closest to the water suction pipe. Since the upper edge 823 of the water retaining rib is located at the upper side in the vertical direction and the lower edge 824 of the water retaining rib is located at the lower side in the vertical direction, the inner peripheral side edge 825 of the water retaining rib is an inclined hypotenuse that slopes downward from the upper side to the lower side. That is to say, the water retaining rib 820 is arranged as an inclined sheet structure. At the same time, the inclination direction of the inner peripheral side edge 825 of the water retaining rib is inclined downward along the rotation direction of the water suction pipe 410, that is, from the perspective of vertical top view, when the water suction pipe 410 rotates in the clockwise direction, the water retaining rib 820 is arranged to slope downward from top to bottom in the clockwise direction; on the contrary, when the water suction pipe 410 rotates in the counterclockwise direction, the water retaining rib 820 is arranged to slope downward from top to bottom in the counterclockwise direction. On the other hand, the inner peripheral side edge 825 of the water retaining rib is arranged as a curved arc edge, and the bending direction is that the center of the arc edge is located above the water retaining rib 820, as Figure 12As shown. That is to say, the inner peripheral side 825 of the water retaining rib is set to a shape protruding downward, and this downward direction can be vertically downward or obliquely downward. In this embodiment, the inner peripheral side 825 of the water retaining rib is set to be a section of an arc of a circle with a radius of 35 mm; on the other hand, the tangent line at the lower end of the inner peripheral side 825 of the water retaining rib is a line parallel to the horizontal line, that is, when the liquid blocked by the water blocking surface 810 flows downward along the water retaining rib 820 to the lower end of the water retaining rib 820, the speed can be reduced, and the flow tends to be stable so as not to disturb the liquid around the suction pipe 410. The radial distance between the inner peripheral side 825 of the water retaining rib and the suction pipe 410 remains consistent. For example, when the suction pipe 410 is formed into an inverted frustum structure and the water blocking surface 810 is formed into a cylindrical side surface shape, the protruding amount (i.e., the protruding length) of the water retaining rib 820 from the water blocking surface 810 to the suction pipe 410 gradually increases from the upper end of the water retaining rib 820 to the lower end of the water retaining rib 820, that is, the lower end of the inner peripheral side 825 of the water retaining rib is set to be closer to the suction pipe 410 than other parts. As observed from a vertical top view, the lower end of the inner peripheral side 825 of the water retaining rib protrudes towards the suction pipe 410. In this embodiment, the radial distance between the inner peripheral side 825 of the water retaining rib and the suction pipe is approximately maintained at 10 mm. It should be noted that the so-called radial distance remaining consistent here does not mean that it must be equal, and there can be a certain floating error up and down in the manufacturing process.

[0102] The upper side surface 821 of the water retaining rib is a surface facing upward formed by jointly surrounding the upper edge 823 of the water retaining rib, the lower edge 824 of the water retaining rib, and the inner peripheral side 825 of the water retaining rib. In this embodiment, since the inner peripheral side 825 of the water retaining rib is set to a curved arc edge inclined downward along the rotation direction of the suction pipe 410, the upper side surface 821 of the water retaining rib is a curved arc surface inclined downward along the rotation direction of the suction pipe 410. At the same time, the upper side surface 821 of the water retaining rib is also set to a shape inclined upward towards the side away from the water blocking surface 810 (i.e., towards the suction pipe 420), that is, in the vertical section of the diameter of the water blocking surface 810, the included angle between the upper side surface 821 of the water retaining rib and the water blocking surface 810 is an acute angle.

[0103] The lower side surface 822 of the water retaining rib is a surface facing downward formed by jointly surrounding the upper edge 823 of the water retaining rib, the lower edge 824 of the water retaining rib, and the inner peripheral side 825 of the water retaining rib. In this embodiment, since the inner peripheral side 825 of the water retaining rib is set to a curved arc edge inclined downward along the rotation direction of the suction pipe 410, the lower side surface 822 of the water retaining rib is a curved arc surface inclined downward along the rotation direction of the suction pipe. That is to say, the upper side surface 821 of the water retaining rib and the lower side surface 822 of the water retaining rib are opposite and have the same shape and size. In this embodiment, the angle formed by the tangent lines at the upper end and the lower end of the lower side surface 822 of the water retaining rib is 106°.

[0104] The above is a detailed description of the structure of the liquid fragmentation unit 100. In addition, the air treatment device 10 may also be equipped with various functional units designed according to different product positions, such as an air dehumidification unit, an air guiding unit, a heat exchange unit, a filtering unit, a sterilization unit, etc. The detailed description of other functional units is omitted in the present invention.

[0105] Next, with reference to Figure 13 the air flow direction inside the air treatment device 10 will be described. Figure 13 It is a side sectional view showing the air flow in the air treatment device according to the present invention.

[0106] In order to ensure the unity and smoothness of the air duct at the liquid fragmentation unit 100, a wind baffle 500 for blocking air and guiding the air to flow into the inside of the water storage part 200 can be provided above the water storage part 200 of the liquid fragmentation unit 100. The wind baffle 500 is provided as a curved arc-shaped plate and extends downward from the top surface of the housing 11, and an opening is provided on the air inlet side of the liquid fragmentation unit 100 (i.e., the left side of the liquid fragmentation unit in the figure). When observed in the vertical direction of the liquid fragmentation unit 100, the projection of the fragmentation part 400 is located inside the enclosure of the wind baffle 500, and the projection of the wind baffle 500 is located inside the enclosure of the water storage part 200.

[0107] The air outside the air treatment device 10 is first sucked into the inside of the housing 11 from the air suction port 12 of the housing 11 by the driving of the air supply device. After the air is processed or guided by, for example, the air guiding structure 300 or other functional units, it reaches the air inlet side of the liquid fragmentation unit 100 (i.e., the left side of the liquid fragmentation unit 100 shown in the figure), and then enters the liquid fragmentation unit 100. Then, due to the blocking of the wind baffle 500, the air can only flow downward after hitting the wind baffle 500. That is to say, the wind baffle 500 can guide the air into the liquid fragmentation unit 100 and prevent the air from directly blowing towards the air discharge port 14 without passing through the liquid fragmentation unit 100. At this time, when the air passes through the positions of the first water lifting plate 420 and the second water lifting plate 430 of the fragmentation part 400, it is mixed with the liquid particles refined by the fragmentation part 400, and then continues to flow into the water storage part 200. Then, due to the blocking of the liquid stored in the water storage part 200, the air turns again and flows out through the outlet between the wind baffle 500 and the water storage part 200. After completely leaving the liquid storage space 270 surrounded by the water storage part 200, it flows towards the air discharge port 14 of the housing 11 and is finally discharged to the outside of the air treatment device 10 through the air discharge port 14.

[0108] Next, with reference to Figure 8 the method of fragmenting and refining the liquid by the fragmentation part 400 according to the present invention will be described.

[0109] When the air handling device 10 is in operation, the motor 610 is powered on and rotates at a high speed. The rotational motion is transmitted to the rotating plate 630 through the rotating shaft 620, causing the rotating plate 630 to rotate, thereby driving the first water lifting plate 420 and the water suction pipe 410 connected to the rotating plate 630 to rotate at a high speed. At the same time, the water supply unit supplies liquid to the water storage unit 200. Since the water suction port 412 at the lower end of the water suction pipe 410 is immersed in the liquid stored in the water storage unit 200, the centrifugal force generated by the high-speed rotation of the water suction pipe 410 enables the liquid in the water storage unit 200 to enter the hollow space of the water suction pipe 410 through the water suction port 412 and climb upward along the inner wall of the barrel wall 411 of the water suction pipe 410. At the same time, the water suction pipe 410 is provided with a hollow structure in the shape of an inverted frustum, that is, the inner wall of the barrel wall 411 is an inclined surface that expands upward. In this way, the liquid located on the inner wall of the barrel wall 411 is not easily dropped under the action of the centrifugal force and moves upward along the inclined surface more effectively. The water lifting ribs 417 provided at the water suction port 412 are used to drive the liquid upward during high-speed rotation. Specifically, when the water lifting ribs 417 rotate with the water suction pipe 410, the water lifting ribs 417 and the liquid are in relative motion. Due to the blockage of the water lifting ribs 417, the liquid flows upward in the direction in which the water lifting ribs 417 extend (that is, the axial direction of the water suction pipe 410, which is the vertical up and down direction), thereby achieving the effect of driving the liquid upward.

[0110] Then, after the liquid in the water storage unit 200 enters the inner wall of the barrel wall 411 of the water suction pipe 410 through the water suction port 412, it gradually moves upward along the inclined wall of the inner wall to the position where the fine water spray holes 414 are provided at the upper part of the water suction pipe 410. Since there is no support from the barrel wall 411, the liquid immediately passes through the fine water spray holes 414 and sprays out in the centrifugal direction and leaves the barrel wall 411. At this time, the liquid ejected from the fine water spray holes 414 is broken into tiny particle shapes. It should be noted that the degree of fragmentation (degree of fineness) of the liquid is affected by factors such as the rotation speed of the water suction pipe 410, the shape of the water suction pipe 410, the shape, size and position of the fine water spray holes 414, etc. Those skilled in the art can make corresponding design adjustments to the above structure according to the actual product requirements.

[0111] Subsequently, some of the liquid particles ejected from the fine water spray holes 414 reach the second water pumping plate 430 and adhere to the second water pumping plate 430. Specifically, after the liquid particles are ejected from the fine water spray holes 414, since the upper side surface of the inner peripheral side end of the water pumping plate curved surface 415 is closely arranged below the corresponding fine water spray holes 414, most of the liquid particles immediately contact the water pumping plate curved surface 415 after leaving the fine water spray holes 414, so that they adhere to the water pumping plate curved surface 415, and then continue to flow along the water pumping plate curved surface 415 in the centrifugal direction to the water pumping plate plane 416. Since the second water-suppressing plate 430 and the suction pipe 410 rotate at high speed together, the liquid particles attached to the water-suppressing plate plane 416 will continue to accelerate and be released in the centrifugal direction. During this process, the liquid particles will continue to separate due to the high speed, thereby making their volume finer, or the liquid particles will be thrown out at a higher speed and hit the wind shield 500 or the side 220 of the water storage part, so that the liquid can achieve a more fine (atomized) effect.

[0112] The liquid that is not thrown out from the fine water spray hole 414 in the cylinder wall 11 will eventually be thrown out from the water spray port 413 at the top of the water suction pipe 410 along the first water pumping plate 420 in the centrifugal direction under the action of centrifugal force. The first water pumping plate 420 has the same function as the second water pumping plate 430 described above, which will not be repeated here. In addition, the shape of the rotating plate 630 arranged above the first water pumping plate 420 is similar to that of the first water pumping plate 420 and the second water pumping plate 430, that is, it is a circular flat plate, which can prevent the liquid thrown out from the water spray port 413 from scattering upward randomly and make the liquid escape from the crushing part 600 along the space between the rotating plate 630 and the first water pumping plate 420, thereby preventing the motor 610 located above the water spray port 413 from being splashed by the liquid and causing damage, and at the same time, the liquid can be guided to the first water pumping plate 420 to be further fined.

[0113] Under the action of centrifugal force, the liquid particles are finally thrown away from the first water-lifting plate 420, the second water-lifting plate 430 and the rotating plate 630. On the one hand, the liquid particles with smaller volume and lighter mass will immediately mix with the surrounding air flowing through, and be discharged to the outside of the liquid breaking unit 100 along with the air flow; on the other hand, the liquid particles with larger volume and larger mass are difficult to mix with the air immediately, and continue to be thrown to the side 220 of the water storage part or the windshield 500, and dispersed by colliding with the wall surface, thereby being further micronized. Since the volume and mass of the liquid particles after further micronization are reduced, they can be mixed with the air flowing through, and be discharged to the outside of the liquid breaking unit 100 along with the air flow; on the other hand, the liquid particles with larger volume or mass will fall into the liquid stored in the water storage part 200 due to gravity and be recovered. In this way, the function of humidifying air is achieved.

[0114] Next, refer to Figure 11 ,Figure 12 and Figure 14 The principle and function of the water retaining part 800 according to the present invention will be described in detail.

[0115] When the liquid breaking unit 100 is started, the water supply part supplies a certain amount of liquid to the water storage part 200. Under the guidance of the bottom surface 210 of the water storage part that slopes downward from the side surface 220 of the water storage part to the water storage recess 240, the liquid flows into the water storage recess 240 through the water retaining surface gap 811 between the outer peripheral surface 840 of the water retaining part and the water retaining surface 810 and the bottom surface 210 of the water storage part. The water retaining surface gap 811 is used to control the flow rate of the liquid flowing into the space surrounded by the water retaining part 800. In other words, due to the small interval space, the liquid will not all flow into the space surrounded by the water retaining surface 800 (i.e., around the water suction pipe 410) in a short time, but continuously and stably pass through the water retaining surface gap 811 and enter the surrounding of the water suction pipe 410, thereby improving the stability of the water suction of the water suction pipe 410. At the same time, the height of the water surface around the water suction pipe 410 is controlled to reduce the load on the motor and ensure the required rotational speed. At the same time, the driving part 600 drives the crushing part 400 to rotate at a high speed, and the liquid around the water suction pipe 410 is sucked upward by the water suction port 413 and enters the internal space of the water suction pipe 410.

[0116] When the water suction pipe 410 rotates at a high speed, it will cause the liquid surface to shake. When the liquid surface is near the water suction port 412, this shaking will cause the amount of liquid sucked by the water suction pipe 410 to be unstable (for example, the water suction port 412 intermittently sucks liquid), resulting in unstable humidification amount; at the same time, due to the rotation of the water suction pipe 410, a part of the liquid surge, such as the liquid flowing along the rotation direction in the water storage part 200, or the liquid surge flowing from the water suction pipe 410 to the side surface 220 of the water storage part, will also cause the amount of liquid sucked by the water suction pipe 410 to be unstable, resulting in unstable humidification amount; in addition, due to the intermittent contact and separation between the liquid surface and the water suction port 412, it is also easy to generate noise during water suction and the noise of the surge hitting the side surface 220 of the water storage part.

[0117] In response to this, by setting the water retaining surface 810, when a part of the shaking liquid surge diffuses outward, its shaking degree is weakened by colliding with the water retaining surface 810; at the same time, the surge is blocked and cannot continue to diffuse outward, so that the liquid can be stored to a greater extent in the space surrounded by the water retaining surface 810 (i.e., around the water suction pipe 410), making the amount of liquid around the water suction pipe 410 tend to be stable; in addition, the water retaining surface 810 weakens the surge from continuing to flow to the side surface 220 of the water storage part, thereby reducing the noise of the surge hitting the side surface 220 of the water storage part. That is, the water retaining surface 810 can suppress the instability of the amount of liquid sucked by the water suction pipe 410 and the generation of noise, and improve the stability of the humidification amount.

[0118] Moreover, the horizontal cross-section of the water-retaining surface 810 and the horizontal cross-section of the water suction pipe 410 are both circular rings with the same shape. At the same vertical height, the horizontal cross-section of the water-retaining surface 810 and the horizontal cross-section of the water suction pipe 410 are concentric circles, that is, the distance from the outer periphery of the water suction pipe 410 to the water-retaining surface 810 is equal. In this way, the liquid surge around the water suction pipe 410 can reach the water-retaining surface 810 almost simultaneously after diffusing from the water suction pipe 410, and be weakened simultaneously and then rebound to the periphery of the water suction pipe 410 at the same time, thereby suppressing the chaos caused by surges in different directions, ensuring that the liquid volume around the water suction pipe 410 remains roughly equal at different times, stabilizing the load of the motor 610 of the driving unit 600, and thus stabilizing the rotation speed to maintain a stable humidification amount.

[0119] In addition, when the wave crest of the liquid surge driven by the water suction pipe 410 is relatively high, the waves of the surge may flow over the upper end of the water-retaining surface 810 towards the side 220 of the water storage part. In this case, the amount of liquid returning to the water suction pipe 410 after colliding with the water-retaining surface 810 will decrease; on the other hand, when the water suction pipe 410 rotates at a high speed, the liquid around the water suction port 412 will form a vortex, and the vortex will push the liquid towards the outer peripheral side, reducing the amount of liquid close to the water suction pipe 410. When the liquid surface is located near the water suction port 412, it may cause insufficient liquid at the water suction port 412, resulting in insufficient or uneven humidification amount. Therefore, by providing the water retaining ribs 820, a part of the waves of the surge can be suppressed from flowing over the water-retaining surface 810. At the same time, through the guidance of the water retaining ribs 820, the liquid can flow downward after colliding with the water retaining ribs 820 and return to the vicinity of the water suction port 412. With such a structure, the liquid gathered near the water suction port 412 can be increased, ensuring the liquid volume around the water suction port 412.

[0120] Specifically, taking the example of the water suction pipe 410 rotating counterclockwise in a top view for illustration. Refer to Figure 14 , Figure 14 is a top view showing the flow of the liquid surge in the liquid breaking unit according to the present invention. The water suction pipe 410 rotates counterclockwise, so the surge diffusing outward from the water suction pipe 410 also diffuses counterclockwise. Since the water retaining ribs 820 are inclined downward along the rotation direction of the water suction pipe 410 (i.e., counterclockwise), that is, the inclination direction of the water retaining ribs 820 is the same as or close to the direction of the surge movement, the surge reaching the water retaining ribs 820 collides with the lower side surface 822 of the water retaining ribs along the counterclockwise direction and flows obliquely downward along the guidance of the lower side surface 822 of the water retaining ribs. In this way, the wave crest of the surge can be depressed, and the surge can flow more downward, thereby increasing the liquid gathered near the water suction port 412 and ensuring the liquid volume around the water suction pipe 410.

[0121] The water retaining rib 820 is configured as a sheet-like structure, that is, the side of the water retaining rib 820 facing the water suction pipe 410 does not form a surface, but forms a very thin side edge (refer to the inner peripheral side edge 825 of the water retaining rib). In this way, the surge flowing outward from the water suction pipe 410 will not (or is difficult to) be blocked by the water retaining rib 820. In other words, the inner peripheral side edge 825 of the water retaining rib serves to cut the surge rather than block it, which can greatly reduce the blocking effect of the water retaining rib 820 on the surge diffusing outward from the water suction pipe 410, allowing more surge to flow towards the water retaining surface 810, thereby suppressing the surge chaos caused by the blocking and rebound of different surfaces near the water suction pipe 410, improving the water suction uniformity of the water suction port 412 and thus enhancing the humidification uniformity.

[0122] In this embodiment, the upper side surface 821 of the water retaining rib is provided to be inclined upward in the direction of the water suction pipe 410, which can further prevent liquid from remaining on the upper side surface 821 of the water retaining rib when the liquid breaking unit 100 stops operating, thereby preventing the residual liquid from forming scale due to high temperature or other reasons and accumulating on the upper side surface 821 of the water retaining rib, which would reduce the effect of the water retaining part. Specifically, when the liquid breaking unit 100 stops operating, the accumulated liquid in the water storage part 400 is discharged outside the liquid breaking unit 100 through the drain port 250. At this time, part of the liquid on the upper side surface 821 of the water retaining rib will flow downward along the inclined upper side surface 821 of the water retaining rib, or gather on the side of the upper side surface 821 of the water retaining rib close to the water retaining surface 810 and then flow downward. In other words, such an inclined design of the upper side surface 821 of the water retaining rib is to make the liquid not stay on the upper side surface 821 of the water retaining rib as much as possible.

[0123] The water retaining rib 820 is in an arc shape with the center of the circle located above the water retaining rib 820, which can guide the liquid surge more smoothly. Specifically, although the surge blocked by the water retaining surface 810 is blocked in the outward diffusion movement direction, it will continue to move along another movement direction of its own, that is, the rotation direction of the water suction pipe 410. At this time, the surge is first blocked by the upper end of the water retaining rib 820, and then smoothly continues to move along the rotation direction of the water suction pipe 410 along the lower side surface of the arc-shaped water retaining rib 820 and is "pressed" downward by the water retaining rib 820. The surge flows gradually downward along the curved arc surface from the upper end of the water retaining rib 820 to the lower end of the water retaining rib 820. And since the tangent line at the lower end of the water retaining rib 820 is set to be parallel to the horizontal line, the surge will finally tend to flow horizontally and leave the water retaining rib 820. The surge below tends to flow horizontally and gradually flows into the water storage recess 240, which can improve the uniform distribution of the surge below near the water suction pipe 410, thereby enhancing the humidification uniformity.

[0124] Moreover, the water retaining rib gap 826 is provided to enable the liquid surge guided by the water retaining rib 820 to continue flowing substantially horizontally through the water retaining rib gap 826 and gradually flow into the water storage recess 240 due to gravity during the flow, rather than locally surging into the water storage recess 240 in a short time. Thereby, the uniform distribution of the surge below the vicinity of the water suction pipe 410 is further improved, and thus the humidification uniformity is improved.

[0125] Similarly, the water storage recess 240 is surrounded by the plane where the water retaining surface 810 is located at intervals, enabling the liquid surge guided by the water retaining rib 820 to continue flowing substantially horizontally along the plane between the water retaining surface 810 and the water storage recess 240 and gradually flow into the water storage recess 240 during the flow, rather than locally surging into the water storage recess 240 in a short time. Thereby, the uniform distribution of the surge below the vicinity of the water suction pipe 410 is further improved, and thus the humidification uniformity is improved.

[0126] The water storage recess 240 is provided in a frustum shape with a rounded bottom, allowing the surge to gradually flow into the water storage recess 240 along the side surface 243 of the water storage recess, rather than locally surging into the water storage recess 240 in a short time. Thereby, the uniform distribution of the surge below the vicinity of the water suction pipe 410 is further improved, and thus the humidification uniformity is improved. At the same time, the inclined side surface 243 of the water storage recess guides the surge, which can reduce the noise generated by the direct impact of the surge or splashing water droplets around the water suction port 412 on the wall surface.

[0127] On the other hand, the water retaining ribs 820 are uniformly distributed along the circumferential direction of the water retaining surface 810. For example, four water retaining ribs 820 are provided and are arranged in pairs opposite to each other, which can inhibit the imbalance in the distribution of the guided surge, improve the uniform distribution of the guided surge, and improve the humidification uniformity. The projections of the respective water retaining ribs 820 in the vertical direction are staggered from each other at intervals, which is to prevent the water retaining ribs 820 from overlapping each other and increasing the resistance to the surge, that is, reducing the blockage of the surge and thus inhibiting the chaos of the surge near the water suction pipe 410, improving the water suction uniformity of the water suction port 412 and thus improving the humidification uniformity.

[0128] On the other hand, when the water suction pipe 410 according to the present invention has a frustum shape, the protruding length of the lower end of the water retaining rib 820 from the water retaining surface 810 is set to be greater than the protruding length of other parts of the water retaining rib 820 from the water retaining surface 810, that is, the protruding length of the water retaining rib 820 from the water retaining surface 810 gradually increases from the upper end to the lower end, so that the radial distance between the inner peripheral side 825 of the water retaining rib and the water suction pipe 410 remains consistent. By doing so, the liquid around the water suction pipe 410 can reach the inner peripheral side 825 of the water retaining rib almost simultaneously after diffusing from the water suction pipe 410, that is, it is almost simultaneously cut or blocked by the inner peripheral side 825 of the water retaining rib, thereby suppressing the chaos of the upwelling near the water suction pipe 410, improving the water absorption uniformity of the water suction port 412 and thus improving the humidification uniformity.

[0129] In summary, the present invention provides a liquid breaking unit and an air handling device including the liquid breaking unit. A water retaining part is sleeved near the lower end of the water suction pipe. The water retaining surface and the water retaining rib of the water retaining part are used to prevent the upwelling of the nearby liquid from diffusing outward due to the rotation of the water suction pipe, and effectively, uniformly and stably guide the upwelling colliding with the water retaining surface and the water retaining rib to flow back downward near the water suction pipe, thereby ensuring the stability of the liquid level and liquid flow near the water suction port of the water suction pipe. Thus, on the one hand, a stable humidification amount can be ensured; on the other hand, since the liquid and liquid flow near the water suction port are stable, the motor speed is stable, thereby reducing the noise caused by the unstable motor speed.
