For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0051] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0052] Referring to Figures 1 to 10, according to an embodiment of the present application, a water distribution component is provided, which is applied to cleaning equipment. The water distribution component includes a water distribution component 1 and a shell 2. The water distribution component 1 is provided with at least one water hole, and the shell 2 is provided with at least two water outlets. The water distribution component 1 can be movably arranged in the shell 2 to switch the at least one water hole and the at least one water outlet.

[0053] By providing a housing 2, a mounting location for the water distribution element 1 can be provided. By providing at least two water outlets on the housing 2, at least two discharge paths for the fluid are provided, enabling water supply to at least two functions. The water distribution element 1 is disposed within the housing 2, and at least one water passage hole is provided on the water distribution element 1. The water distribution element 1 is movable within the housing 2. This allows the water distribution element 1 to switch between the water passage hole and at least one of the at least two water outlets according to water supply needs. The corresponding water outlet can be selected for water supply as needed, thereby meeting the water supply needs of different functions while using a single pump body 4.

[0054] The housing 2 encloses a receiving space, and the water distribution element 1 is movably arranged in the receiving space.

[0055] The water hole moves with the water distribution member 1 within the housing 2. When the water hole moves to a position corresponding to the water outlet, the water hole communicates with the corresponding water outlet. When the water hole moves beyond the position corresponding to the water outlet, that is, the portion of the water distribution member 1 excluding the water hole moves to the position corresponding to the water outlet, the portion of the water distribution member 1 excluding the water hole blocks the fluid flow path, thereby disconnecting the water hole from the water outlet.

[0056] The water distribution element 1 can move in the housing 2 in a translational or rotational manner.

[0057] Specifically, the direction of the fluid flowing through the water hole to the corresponding water outlet is defined as the first direction, and the water distribution component 1 can be driven by a power component such as a motor to move in a translation perpendicular to the first direction, for example, in a linear reciprocating motion. During the translation process, when the water hole moves to a position corresponding to the water outlet, the water hole is connected to the corresponding water outlet. When the water hole moves beyond the position corresponding to the water outlet, the connection between the water hole and the water outlet is blocked. In one embodiment, the water distribution component 1 is slidably set on a guide rail, and the motor drives the water distribution component 1 to move back and forth on the guide rail. During the translation process, when the water hole moves to a position corresponding to the water outlet, the water hole is connected to the corresponding water outlet. When the water hole moves beyond the position corresponding to the water outlet, the water distribution component 1 blocks the connection between the water hole and the water outlet.

[0058] Specifically, the water distribution member 1 can be driven by power components such as a motor and transmission components such as gears, and rotate in a plane perpendicular to the first direction and with a point outside the water distribution member 1 as the rotation center, that is, revolve. During the rotation process, when the water hole rotates to a position corresponding to the water outlet, the water hole is connected to the corresponding water outlet. When the water hole rotates beyond the position corresponding to the water outlet, the water distribution member 1 disconnects the water hole from the water outlet. In one embodiment, teeth are provided on the outer peripheral wall of the water distribution member 1, and the water distribution member 1 serves as a planetary gear. A gear is provided on the motor shaft as a center wheel. The center wheel is meshed with the water distribution member 1, and the outer side of the water distribution member 1 is also meshed with the ring gear to form a planetary gear set, thereby driving the water distribution member 1 to rotate around the center wheel. In another embodiment, the motor is connected to the water distribution member 1 through a connecting rod assembly, and then the connecting rod assembly drives the water distribution member 1 to revolve around a point outside the water distribution member 1 as the center.

[0059] Specifically, the water distribution component 1 can be driven by a component that provides power, and rotates in a plane perpendicular to the first direction, with a certain point on the water distribution component 1 itself as the center of rotation, that is, self-rotation. During the self-rotation process, when the water hole rotates to a position corresponding to the water outlet, the water hole is connected to the corresponding water outlet. When the water hole rotates to a position other than the position corresponding to the water outlet, the water distribution component 1 disconnects the water hole from the water outlet. In one embodiment, the water distribution component 1 rotates with its own geometric center as the center of rotation, that is, symmetrical rotation. In one embodiment, the water distribution component 1 rotates with a point other than its own geometric center as the center of rotation, that is, eccentric rotation.

[0060] In this embodiment, the rotation of the water diversion member 1 is used as an example. A positioning shaft 25 is provided on the inner wall of the housing 2 facing the water diversion member 1, along the axial direction of the water diversion member 1. The positioning shaft 25 passes through the rotation center of the water diversion member 1, allowing the water diversion member 1 to be rotatably mounted on the positioning shaft 25. The provision of the positioning shaft 25 ensures the rotational stability of the water diversion member 1.

[0061] Specifically, for example, if water distribution member 1 is disc-shaped and rotates about its own central axis, positioning shaft 25 is disposed through the center of water distribution member 1. That is, water distribution member 1 and positioning shaft 25 are coaxially disposed, allowing water distribution member 1 to rotate about its own central axis on positioning shaft 25. The provision of positioning shaft 25 ensures concentricity between water distribution member 1 and housing 2, and also ensures the stability of water distribution member 1's rotation about its own central axis.

[0062] The water hole may be a circular through hole.

[0063] As a first feasible implementation manner, at least two water outlets include a first water outlet 21 and a second water outlet 22, and the water hole moves with the water distribution component 1 in the shell 2 so that the water hole can be selectively connected to the first water outlet 21 or the second water outlet 22, so that water can be supplied to the first water outlet 21 or the second water outlet 22 according to demand.

[0064] The water hole is controlled to communicate with the first water outlet 21 or the second water outlet 22 by controlling the moving direction of the water diverter 1 in the housing 2 .

[0065] Among them, at least two water outlets include a first water outlet 21 and a second water outlet 22. When the water hole moves with the water diversion component 1 to a position corresponding to the first water outlet 21, the water hole is communicated with the first water outlet 21, so that the fluid can flow into the first water outlet 21 through the water hole, and the water diversion component 1 is opposite to the second water outlet 22 to close the second water outlet 22; when the water hole moves with the water diversion component 1 to a position corresponding to the second water outlet 22, the water hole is communicated with the second water outlet 22, so that the fluid can flow into the second water outlet 22 through the water hole, and the water diversion component 1 is opposite to the first water outlet 21 to close the first water outlet 21, so that the switching water outlet between the first water outlet 21 and the second water outlet 22 can be realized, and the first water outlet 21 or the second water outlet 22 can be selected for water supply according to demand.

[0066] The first water outlet 21 and the second water outlet 22 may correspond to different functions of the cleaning device respectively.

[0067] Among them, the position corresponding to the water hole and the first water outlet 21 refers to the position where the water hole is connected to the first water outlet 21. It can be a position that is axially opposite to and connected to the first water outlet 21, or it can be a position that is not opposite but connected. That is to say, when the water hole is rotated to a position that is connected to the first water outlet 21, then this position is the position corresponding to the first water outlet 21.

[0068] Among them, the position corresponding to the water hole and the second water outlet 22 refers to the position where the water hole is connected to the second water outlet 22. It can be a position that is axially opposite to and connected to the second water outlet 22, or it can be a position that is not axially opposite to but connected to the second water outlet 22. That is to say, when the water hole is rotated to a position where it is connected to the second water outlet 22, then this position is the position corresponding to the second water outlet 22.

[0069] The portion of the water distribution member 1 other than the water hole is solid. When the water hole moves with the water distribution member 1 to a position corresponding to the first water outlet 21, the portion of the water distribution member 1 other than the water hole opposes the second water outlet 22, thereby sealing the second water outlet 22. When the water hole moves with the water distribution member 1 to a position corresponding to the second water outlet 22, the portion of the water distribution member 1 other than the water hole opposes the first water outlet 21, thereby sealing the first water outlet 21.

[0070] The water distribution member 1 is rotatably disposed within the housing 2, with the water flow hole extending through the member 1 along the direction of the rotational axis of the member 1. By arranging the water distribution member 1 to be rotatable within the housing 2, the position of the water flow hole on the member 1 can be switched, thereby switching the water flow hole's connection with at least one water outlet. Specifically, the connection between the water flow hole and the first water outlet 21 and the second water outlet 22 can be switched, thereby enabling water to be supplied to either the first water outlet 21 or the second water outlet 22, respectively. By arranging the water flow hole to extend through the member 1 along the direction of the rotational axis of the member 1, smooth water flow can be ensured.

[0071] The water distribution member 1 may be a disc-shaped structure, and the rotation axis of the water distribution member 1 is parallel to the thickness direction of the water distribution member 1 .

[0072] Specifically, in this embodiment, the water distribution member 1 is a disc-shaped water distribution member 1. The water distribution member 1 rotates around its own central axis. The water holes are provided through the water distribution member 1 along an extending direction parallel to the central axis of the water distribution member 1.

[0073] Among them, at least one water hole includes a first water hole 11, which is arranged on the outer peripheral side of the rotation axis of the water distribution member 1 and extends along the radial direction of the water distribution member 1, so that the first water hole 11 can rotate with the rotation of the water distribution member 1.

[0074] The water distribution member 1 is a disc-shaped structure, and the first water passage hole 11 is provided on the outer peripheral side of the central axis of the water distribution disc.

[0075] The first water passage hole 11 is a strip-shaped hole, and the first water passage hole 11 extends along the radial direction of the water diversion member 1 .

[0076] The flow area of ​​the first water hole 11 decreases radially inwardly of the water distribution member 1 .

[0077] The first water through hole 11 is symmetrical with a radius passing through the center point of the first water through hole 11 in the water distribution member 1 .

[0078] Specifically, the first water hole 11 is roughly fan-shaped.

[0079] As a second feasible embodiment, at least one of the water holes includes a second water hole 12, and the first water hole 11 and the second water hole 12 are arranged circumferentially along the rotation axis of the water distribution member 1. By providing the first water hole 11 and the second water hole 12, in conjunction with at least two water outlets, water can be supplied to one outlet alone or to both outlets simultaneously, thus expanding the water supply methods.

[0080] There can be two water outlets, and the angle formed by the two water outlets in the circumferential direction of the water distribution member 1 is the same as the angle formed by the first water flow hole 11 and the second water flow hole 12 in the circumferential direction of the water distribution member 1. Water can be supplied to both water outlets simultaneously, thereby meeting the water supply requirements of two functions at the same time. Specifically, the angle formed by the two water outlets in the circumferential direction of the water distribution member 1 can be 90°, and the angle formed by the first water flow hole 11 and the second water flow hole 12 in the circumferential direction of the water distribution member 1 is also 90°.

[0081] Among them, there can be two water outlets, and the angle formed by the two water outlets in the circumferential direction of the water distribution component 1 is different from the angle formed by the first water hole 11 and the second water hole 12 in the circumferential direction of the water distribution component 1. Water can be supplied to one of the water outlets and the other water outlet is closed. When water needs to be supplied to the other water outlet, the water distribution component 1 only needs to be rotated by a smaller angle, thereby reducing the rotation time of the water distribution component 1.

[0082] There can be three water outlets, evenly spaced about the circumference of the water distribution member 1. The first water hole 11 and the second water hole 12 can simultaneously face and communicate with two of the three water outlets, allowing water to be supplied from two of the three outlets, thereby simultaneously satisfying the water supply requirements of both functions. Specifically, the angle formed by the three water outlets about the circumference of the water distribution member 1 is 120°, and the angle formed by the first water hole 11 and the second water hole 12 about the circumference of the water distribution member 1 is also 120°.

[0083] As a third feasible embodiment, at least one of the water holes includes a third water hole 13. The third water hole 13 extends circumferentially around the rotation axis of the water distributor 1 and is in communication with at least one water outlet. By providing the third water hole 13 and maintaining communication with the at least one water outlet, water is continuously supplied to the at least one water outlet, enabling continuous water supply and further expanding the water supply options.

[0084] The third water passage hole 13 is substantially an annular hole and is coaxially arranged with the water distribution member 1 .

[0085] Specifically, the majority of the third water passage 13 extends axially through the water distribution member 1. A small portion of the third water passage 13 does not extend axially through the water distribution member 1, preserving a substantial portion of the water distribution member 1. This ensures that the water distribution member 1 is not divided into two separate sections by the third water passage 13. This retained portion of the water distribution member 1 is referred to as a first connecting segment 131. The first connecting segments 131 are evenly distributed within the third water passage 13 along the circumference of the water distribution member 1.

[0086] Specifically, the thickness of the first connecting section 131 along the axial direction of the water diversion member 1 is smaller than the thickness of the water diversion member 1 in the axial direction, so that the third water holes 13 are connected to form a ring along the circumference of the water diversion member 1 .

[0087] More specifically, as shown in FIG9 , the number of the first connecting segments 131 may be three.

[0088] The water outlet corresponding to the third water hole 13 may also be annular in shape and disposed opposite the third water hole 13 in the axial direction of the water diverter 1, such that the third water hole 13 and the corresponding water outlet remain in communication during the rotation of the water diverter 1. The water outlet corresponding to the third water hole 13 may also be non-annular in shape; such outlet and the third water hole 13 may remain in communication even if they remain opposite each other during the rotation of the water diverter 1.

[0089] The third water hole 13 , the water outlet corresponding to the third water hole 13 , and the water distribution component 1 are all coaxially arranged, and the axis is the central axis of the water distribution component 1 .

[0090] In one embodiment, the water distribution member 1 is provided with a first water hole 11 and a third water hole 13. The water distribution member 1 moves so that the first water hole 11 can switch the corresponding water outlet, and the third water hole 13 can maintain continuous communication with the corresponding water outlet.

[0091] The water distribution assembly includes a static piece 3, which is arranged in the shell 2 and is located between the water distribution member 1 and the side wall of the shell 2 where the water outlet is located. The static piece 3 is provided with at least two water flow grooves, and the water flow grooves are arranged corresponding to the water outlet. The water distribution member 1 can rotate relative to the static piece 3 so that when the water flow hole rotates with the water distribution member 1 to be opposite to the water flow groove, the water flow hole and the water outlet are connected.

[0092] By providing at least two water flow grooves on the static plate 3, and aligning the water flow grooves with the water outlets, fluid can flow through the water flow grooves into the corresponding water outlets, achieving water discharge. By arranging the static plate 3 between the water distribution member 1 and the side wall of the housing 2 where the water outlet is located, the static plate 3 can seal the flow path between the water distribution member 1 and the housing 2.

[0093] Among them, the water trough and the water outlet are set in one-to-one correspondence.

[0094] The flow area of ​​the water trough is greater than or equal to the flow area of ​​the water outlet, so that the fluid flows more smoothly.

[0095] Specifically, the water channel can be a fan-shaped through channel.

[0096] The shape of the static piece 3 can be the same as that of the water diversion element 1 .

[0097] The size of the static piece 3 can be the same as that of the water distribution element 1 .

[0098] Specifically, the static piece 3 may be circular, and the diameter of the static piece 3 is the same as the diameter of the water diversion member 1 .

[0099] The static plate 3 and the water distribution member 1 are coaxially arranged.

[0100] The center of the static piece 3 is passed through the positioning shaft 25 of the housing 2 to position the static piece 3 on the housing 2. In other words, the centers of the static piece 3 and the water distribution member 1 are both passed through the positioning shaft 25 of the housing 2 to ensure that the housing 2, the static piece 3, and the water distribution member 1 have good concentricity and maintain a concentric position.

[0101] The static plate 3 abuts against the water distribution member 1 to close the water hole when the water groove and the water hole are interlaced, thereby ensuring a good sealing effect.

[0102] The end surface of the static plate 3 is in abutment with the end surface of the water distribution member 1 to form a seal, thereby preventing the fluid from flowing into the space between the static plate 3 and the water distribution member 1 when flowing from the water hole to the water groove.

[0103] When the portion of the water distribution member 1 other than the water hole faces the water channel of the static plate 3, the static plate 3 seals against the water distribution member 1, thereby closing the water channel. Simultaneously, when the portion of the static plate 3 other than the water channel faces the water channel of the water distribution member 1, the static plate 3 seals against the water channel, thereby closing the water channel, thereby blocking the connection between the water channel and the water channel, and thus blocking the connection between the water channel and the water outlet.

[0104] The water troughs and the water outlets are arranged one by one opposite to each other, and the water troughs are arranged along the circumference of the static plate 3 .

[0105] The water trough and the water outlet are arranged opposite to each other along the axial direction of the water distribution member 1 .

[0106] Specifically, in this embodiment, the number of the water flow grooves may be three, and the three water flow grooves are arranged along the circumference of the static plate 3 with the central axis of the static plate 3 as the center.

[0107] Specifically, the three water troughs are all fan-shaped through grooves, and the center lines of the fan-shaped formed by the three water troughs are evenly arranged along the circumference of the static plate 3 with the central axis of the static plate 3 as the center, and the center lines of the fan-shaped formed by the water troughs intersect perpendicularly with the central axis of the corresponding water outlet.

[0108] The at least two water channels include a first water channel 31, which extends radially along the static plate 3. By arranging the first water channel 31 to extend radially along the static plate 3, the shape of the first water channel 31 is adapted to the shape of the first water hole 11, ensuring a good flow effect.

[0109] The width of the portion of the first water channel 31 opposite to the corresponding water outlet is smaller than the diameter of the corresponding water outlet.

[0110] The flow area of ​​the first water channel 31 decreases radially inwardly along the static plate 3, so that the shape of the first water channel 31 matches the shape of the first water hole 11, ensuring a good flow effect.

[0111] The first water channel 31 is fan-shaped, and the center line extends along the radial direction of the static plate 3 .

[0112] The flow area of ​​the first water channel 31 is smaller than the flow area of ​​the water hole. That is, the area of ​​the fan-shaped section formed by the first water channel 31 is smaller than the area of ​​the fan-shaped section formed by the first water hole 11 .

[0113] The at least two water channels include a second water channel 32 and a third water channel 33. The first water channel 31, the second water channel 32, and the third water channel 33 are arranged along the circumference of the static plate 3. The second water channel 32 and the third water channel 33 extend along the circumference of the static plate 3. By providing the second water channel 32 and the third water channel 33, the water holes can be connected to the water outlet through the second water channel 32 and the third water channel 33, respectively, so that water can be supplied to different functions separately and the stability of the water supply is guaranteed.

[0114] The second water channel 32 may be a fan-shaped through channel. The third water channel 33 may be a fan-shaped through channel.

[0115] The first water channel 31 , the second water channel 32 and the third water channel 33 are arranged along the circumference of the static plate 3 with the central axis of the static plate 3 as the center.

[0116] Specifically, the center lines of the first water flow channel 31 , the second water flow channel 32 and the third water flow channel 33 are evenly arranged along the circumference of the static plate 3 with the central axis of the static plate 3 as the center.

[0117] The second water channel 32 and the second water outlet 22 are disposed opposite to each other along the axial direction of the second water outlet 22 .

[0118] The flow area of ​​the second water channel 32 is larger than the flow area of ​​the second water outlet 22 .

[0119] The third water trough 33 and the third water outlet 23 are arranged opposite to each other along the axial direction of the third water outlet 23 .

[0120] The flow area of ​​the third water channel 33 is larger than the flow area of ​​the third water outlet 23 .

[0121] The flow area of ​​the second water channel 32 is the same as the flow area of ​​the third water outlet 23 .

[0122] Specifically, the second water channel 32 and the third water channel 33 have the same shape and size.

[0123] The flow areas of the second water channel 32 and the third water channel 33 are larger than the flow area of ​​the water hole.

[0124] The flow areas of the second water channel 32 and the third water channel 33 are larger than the flow area of ​​the first water hole 11 .

[0125] Specifically, the first water hole 11, the second water trough 32 and the third water trough 33 are all fan-shaped holes. The area of ​​the fan formed by the second water trough 32 and the third water trough 33 is larger than the area of ​​the fan formed by the first water hole 11. According to the water supply demand, the projection of the first water hole 11 on the plane where the static plate 3 is located can be rotated to the second water trough 32 or the third water trough 33 to adjust the flow rate to the maximum.

[0126] At least two water troughs include a fourth water trough 34, which extends circumferentially around the center point of the static plate 3. The fourth water trough 34 is connected to at least one water hole and at least one water outlet respectively. When other water holes are not connected to other water troughs, water can be continuously supplied to at least one water outlet at all times. It can be suitable for the function of continuous water supply, further expanding the water supply method.

[0127] The fourth water channel 34 is disposed corresponding to the third water hole 13 .

[0128] The fourth water channel 34 is a substantially annular hole and is coaxially arranged with the static plate 3. The fourth water channel 34 may not be annular. During the rotation of the water diverter, the fourth water channel 34 may remain opposite to the water outlet and the third water channel 13 to maintain communication.

[0129] The fourth water channel 34 and the third water hole 13 are arranged opposite to each other in the axial direction of the water distribution member 1 , so that the third water hole 13 and the fourth water channel 34 remain in communication during the rotation of the water distribution member 1 .

[0130] The third water hole 13 , the fourth water channel 34 , the static plate 3 and the water distribution element 1 are all coaxially arranged, and the axis is the central axis of the water distribution element 1 .

[0131] The fourth water channel 34 can completely penetrate the stator 3, thereby dividing the stator 3 into an outer ring and an inner circular portion. Alternatively, the fourth water channel 34 can extend through the stator 3 axially for the majority of the portion, leaving a small portion of the portion not extending axially therethrough, thereby retaining a substantial portion of the stator 3. This ensures that the stator 3 is not separated into two separate portions by the fourth water channel 34. This retained portion of the stator 3 can be referred to as the second connecting segment 341. The second connecting segment 341 is evenly distributed within the fourth water channel 34 along the circumference of the stator 3.

[0132] Specifically, the thickness of the second connecting section 341 along the axial direction of the static plate 3 is smaller than the thickness of the static plate 3 in the axial direction, so that the fourth water flow channel 34 is connected to form a ring along the circumference of the static plate 3 .

[0133] More specifically, as shown in FIG10 , the number of the second connecting segments 341 may be two.

[0134] In the circumferential direction of the static plate 3 , the water outlet is arranged at the center of the corresponding water channel.

[0135] The center line of the first water channel 31 intersects perpendicularly with the center axis of the first water outlet 21. In the radial direction of the static plate 3, the first water outlet 21 is approximately located at the center of the first water channel 31.

[0136] The center line of the second water channel 32 intersects perpendicularly with the center axis of the second water outlet 22. In the radial direction of the static plate 3, the second water outlet 22 is approximately located at the center of the second water channel 32.

[0137] The center line of the third water channel 33 intersects perpendicularly with the center axis of the third water outlet 23. In the radial direction of the static plate 3, the third water outlet 23 is approximately located at the center of the third water channel 33.

[0138] The overlapping angle range of the water hole and the water trough is adjustable, and the flow rate of the fluid entering the water trough through the water hole can be adjusted, thereby adjusting the water supply provided to the corresponding function.

[0139] The angular overlap range between the water hole and the water groove refers to the angular overlap range between the water hole and the water groove in the axial direction of the static plate 3, that is, the angular overlap range between the projection of the water hole on the plane where the static plate 3 is located and the water groove.

[0140] Specifically, water distribution element 1 is driven to rotate about its own central axis, and the angle of rotation is adjustable. This allows the angle of rotation of water distribution element 1 to be adjusted as needed, thereby controlling the flow rate of fluid discharged to the outlet and meeting the water supply requirements of different functions. When the water supply demand is high, the angle of overlap can be increased. When the workload is maximized, the projection of first water distribution hole 11 on the plane of static plate 3 rotates to within the second water channel 32 or third water channel 33. When the water supply demand is low, the angle of overlap can be reduced.

[0141] In another aspect of this embodiment, a water supply device is provided, comprising the water distribution assembly as described above.

[0142] The water supply device includes a pump body 4 , a housing 2 is buckled on the pump body 4 , and a water distribution component 1 is connected to the pump body 4 so that the pump body 4 drives the water distribution component 1 to move in the housing 2 .

[0143] By connecting the water distribution member 1 with the pump body 4, the pump body 4 can drive the water distribution member 1 to move, making full use of the existing power source, avoiding the addition of other driving components, and effectively controlling the manufacturing cost.

[0144] The housing 2 is fixed on the pump body 4 , and the housing 2 does not rotate along with the rotation of the pump body 4 .

[0145] The water distribution component 1 is connected to the moving component of the pump body 4 so that the moving component of the pump body 4 drives the water distribution component 1 to move.

[0146] Specifically, the water distribution element 1 is connected to a rotatable component in the pump body 4, so that the rotatable component drives the water distribution element 1 to rotate with its own central axis as the rotation center.

[0147] The pump body 4 may be a peristaltic pump.

[0148] The pump body 4 includes a pump head 41, which can rotate to drive the flow of fluid. A first connecting structure is provided on the water distribution component 1, and a second connecting structure is provided on the pump head 41. The first connecting structure is connected to the second connecting structure so that the pump head 41 drives the water distribution component 1 to rotate in the housing 2.

[0149] By arranging the water distribution member 1 on the pump head 41 , the water distribution member 1 can be rotated stably, and the water supply can be distributed according to the water supply cycle of the pump head 41 , thereby achieving accurate water supply.

[0150] The pump body 4 is a peristaltic pump, and the pump body 4 also includes a driving component, which is connected to the pump head 41 and is used to drive the pump head 41 to rotate, thereby driving the fluid in the hose to flow through the rotation of the pump head 41.

[0153] The water distribution member 1 is arranged on the pump head 41, so that the pump head 41 forms the rear shell of the water distribution assembly. That is, the rear shell of the water distribution assembly and the pump head 41 are an integrated structure.

[0154] The end surface of the pump head 41 close to the water distribution member 1 is flat so as to be connected to the water distribution member 1 .

[0155] The water distribution component 1 is detachably connected to the pump head 41 via the first connection structure and the second connection structure, so that the water distribution component 1 can be disassembled and replaced.

[0157] The shape and size of the connecting hole 14 match those of the connecting block 42 , so as to avoid or reduce shaking of the water distribution component 1 on the pump head 41 when the pump head 41 drives the water distribution component 1 to rotate.

[0158] The connecting block 42 protrudes from the end surface of the pump head 41 facing the water diverter 1 along the axial direction of the water diverter 1. The connecting hole 14 on the water diverter 1 is formed along the axial direction of the water diverter 1, so that the connecting hole 14 can be inserted into the connecting hole 14 along the axial direction of the water diverter 1, thereby achieving a detachable connection between the water diverter 1 and the pump head 41, and allowing the pump head 41 to drive the water diverter 1 to rotate through the connecting hole 14.

[0159] A seal may be provided between the connection hole 14 and the connection block 42 to prevent the fluid from flowing out through the gap between the connection hole 14 and the connection hole 14. Alternatively, the connection hole 14 and the connection block 42 may be tightly fitted together to achieve sealing.

[0160] The cross section of the connecting block 42 may be fan-shaped, and the connecting hole 14 is a fan-shaped hole corresponding to the connecting block 42 .

[0165] The pump head 41 , the water distribution member 1 and the static plate 3 are coaxially arranged to ensure the stability of water supply to the water channel of the static plate 3 when the pump head 41 and the water distribution member 1 rotate.

[0166] The end surface of the pump head 41 facing the water distribution member 1 can also be circular. That is, the end surface of the pump head 41 facing the water distribution member 1, the water distribution member 1, and the static plate 3 are all circular and coaxially arranged. The pump head 41 drives the water distribution member 1 to rotate coaxially and remains coaxial with the static plate 3 during the rotation.

[0167] A receiving cavity 5 is provided between the end face of the pump head 41 and the water distribution member 1. The housing 2 is provided with a water inlet 24. The receiving cavity 5 is connected to the water hole and the water inlet 24. The receiving cavity 5 provides a space for the fluid and also buffers the flow.

[0168] There is a distance between the end surface of the pump head 41 excluding the connection block 42 and the end surface of the water distribution component 1 excluding the connection hole 14 to form an accommodating chamber 5 .

[0169] Specifically, the accommodating chamber 5 is formed by the housing 2 , the end surface of the pump head 41 excluding the connecting block 42 , and the water distribution component 1 excluding the connecting hole 14 .

[0170] The accommodating cavity 5 is a substantially cylindrical space.

[0171] The water hole is located on the axial side of the cylindrical shape formed by the accommodating chamber 5. The water inlet 24 of the housing 2 is located approximately on the radial side of the cylindrical shape formed by the accommodating chamber 5. This creates an angle between the direction of fluid entering the accommodating chamber 5 and the direction of fluid exiting the accommodating chamber 5, which provides a buffering effect on the fluid.

[0172] Specifically, the angle between the direction in which the fluid enters the accommodating chamber 5 and the direction in which the fluid exits the accommodating chamber 5 is approximately 90°.

[0173] The water inlet 24 is connected to the drain outlet of the pump body 4, so that the pump body 4 can stably supply water to the water distribution component.
