[0056] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0058] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0059] As shown in Figures 1 to 6, the present disclosure first provides a liquid delivery device. This liquid delivery device can simultaneously deliver liquids in at least three ways and can precisely control the flow rate and speed of liquid delivery. The liquid can be water, but is not limited to this. The liquid can also be a detergent, etc., and can be set according to actual needs.

[0060] 1 to 3 , the liquid delivery device may include: a housing 1, an extrusion device 2, a power transmission assembly 3, and at least three liquid delivery pipelines 4. The housing 1 may have a housing cavity; the extrusion device 2 may be disposed in the housing cavity, and the extrusion device 2 may include an extrusion portion 21; the power transmission assembly 3 may be connected to the extrusion portion 21 to drive the extrusion portion 21 to rotate along a first direction X; and the at least three liquid delivery pipelines 4 may be spaced apart along a second direction Y, and the liquid delivery pipelines 4 may include a liquid inlet 41, an intermediate section 42, and a liquid outlet 43. The intermediate section 42 of each liquid delivery pipeline 4 may be partially located between the extrusion portion 21 and the housing 1, and the intermediate section 42 of each liquid delivery pipeline 4 may partially surround the extrusion portion 21.

[0061] The first direction X is the circumferential direction of the extrusion portion 21 , and the second direction Y is the axial direction of the extrusion portion 21 .

[0062] The liquid delivery device provided in the present disclosure is provided with an extrusion device 2, a power transmission device, and at least three liquid delivery pipelines 4. The power device can be connected to the extrusion portion 21 of the extrusion device 2 to drive the extrusion portion 21 to rotate in a first direction X, thereby continuously squeezing the liquid delivery pipeline 4 by utilizing the rotation of the extrusion portion 21, so that the liquid inlet 41 of the liquid delivery pipeline 4 is negatively pressurized and the liquid outlet 43 is positively pressurized, thereby enabling liquid to flow from the liquid inlet 41 of the liquid delivery pipeline 4 to the liquid outlet 43, thereby achieving liquid delivery.

[0063] Furthermore, the liquid delivery device provided by the present disclosure is provided with at least three liquid delivery pipelines 4, thereby enabling simultaneous delivery of at least three liquids. Furthermore, by spacing the at least three liquid delivery pipelines 4 along the second direction Y, the present disclosure can prevent adjacent liquid delivery pipelines 4 from squeezing or rubbing against each other, thereby preventing damage to the liquid delivery pipelines 4 and the resulting leakage.

[0064] In addition, the present disclosure can set the extrusion part 21 of different sizes according to actual needs, so that the extrusion force of the extrusion part 21 on the liquid delivery pipeline 4 can be accurately controlled according to actual needs, thereby accurately controlling the flow rate and speed of liquid delivery according to actual needs.

[0065] In one embodiment of the present disclosure, the extrusion device 2 may further include a plurality of partitions 22. The plurality of partitions 22 may separate the extrusion portion 21 into at least three sub-extrusion portions 211. The at least three sub-extrusion portions 211 may be spaced apart along the second direction Y, and at least one liquid delivery pipeline 4 may be provided between each sub-extrusion portion 211 and the housing 1. With this arrangement, the plurality of liquid delivery pipelines 4 may be separated by the plurality of partitions 22, thereby further preventing mutual extrusion or friction between the plurality of liquid delivery pipelines 4, thereby further preventing damage to the liquid delivery pipelines 4 and leakage, thereby increasing the service life of the liquid delivery device.

[0066] In one embodiment, multiple partitions 22 can separate the extrusion portion 21 into three sub-extrusion portions 211, and three liquid delivery lines 4 can be provided, with a liquid delivery line 4 being provided between each sub-extrusion portion 211 and the housing 1. This arrangement enables the liquid delivery device to simultaneously deliver three liquids, while ensuring that each liquid delivery line 4 is separated by the partitions 22. This completely prevents the problems of mutual compression or friction between the liquid delivery lines 4, further reducing the probability of damage to the liquid delivery lines 4 and leakage.

[0067] However, the present invention is not limited thereto. In this embodiment, the number of sub-extrusion parts 211 may not be three, and the number of liquid delivery pipelines 4 may not be three. As long as the number of sub-extrusion parts 211 and the number of liquid delivery pipelines 4 are the same, for example, the number of sub-extrusion parts 211 may be four, and the number of liquid delivery pipelines 4 may be four. These can be selected and configured according to actual needs, and are all within the scope of protection of the present disclosure.

[0068] In one embodiment of the present disclosure, the partition 22 can be arranged around the outer circumference of the extrusion portion 21. This arrangement can increase the separation range of the partition 22, improve the separation capacity of the partition 22, and further prevent the liquid delivery pipelines 4 located on both sides of the partition 22 from being squeezed or rubbed.

[0069] The partition 22 can be connected to the outer peripheral surface of the extrusion portion 21. This configuration can improve the connection strength and stability of the partition 22, thereby preventing it from falling off during use. This can also prevent the liquid delivery pipelines 4 on both sides of the partition 22 from being squeezed or rubbed after the partition 22 falls off, ensuring that the liquid delivery pipelines 4 on both sides of the partition 22 will not be damaged during use.

[0070] In one embodiment, the partition 22 and the extrusion portion 21 can be an integrated structure. That is, it is understood that the partition 22 and the extrusion portion 21 can be manufactured through an integrated process, without the need to connect the partition 22 and the extrusion portion 21 together using screws, welding, adhesives, or other connection methods. This configuration can reduce the number of connection points between the partition 22 and the extrusion portion 21, thereby further increasing the connection strength and stability between the partition 22 and the extrusion portion 21, and further avoiding the problem of the partition 22 separating from the extrusion portion 21 during use.

[0071] However, the present invention is not limited thereto, and the partition portion 22 and the extrusion portion 21 may also be of a split structure, that is, the partition portion 22 and the extrusion portion 21 may be manufactured separately and then connected together by screw connection, welding, bonding, etc. This arrangement can significantly reduce the difficulty of manufacturing the extrusion device 2.

[0072] In one embodiment of the present disclosure, as shown in Figures 2 to 5, the extrusion device 2 may include a first extrusion device 23 and a second extrusion device 24. The first extrusion device 23 may include at least one sub-extrusion portion 211. The second extrusion device 24 may be disposed adjacent to and connected to the first extrusion device 23 along the second direction Y, and a partition 22 may be disposed adjacent to the second extrusion device 24 and the first extrusion device 23. The second extrusion device 24 may include at least two sub-extrusion portions 211.

[0073] It should be noted that, in this embodiment, the first extrusion device 23 and the second extrusion device 24 are split structures.

[0074] The present disclosure optimizes the assembly process of the liquid delivery device by decomposing the extrusion device 2 into the first extrusion device 23 and the second extrusion device 24. Specifically, when assembling the liquid delivery device, the first extrusion device 23 and the liquid delivery pipeline 4 located between the sub-extrusion portion 211 of the first extrusion device 23 and the housing 1 can be assembled first. Furthermore, when assembling the second extrusion device 24, the position of the liquid delivery pipeline 4 located between the sub-extrusion portion 211 of the first extrusion device 23 and the housing 1 can be adjusted to ensure the position accuracy of the liquid delivery pipeline 4, thereby ensuring the accuracy of the flow rate and flow rate of the delivered liquid and reducing the probability of damage to the liquid delivery pipeline 4.

[0075] Moreover, after assembling the second extrusion device 24 and the liquid delivery pipeline 4 between the sub-extrusion portion 211 of the second extrusion device 24 and the shell 1, the position of the liquid delivery pipeline 4 between the sub-extrusion portion 211 of the second extrusion device 24 and the shell 1 can be adjusted to ensure the position accuracy of the liquid delivery pipeline 4, thereby ensuring the accuracy of the flow rate and flow of the liquid it delivers, and reducing the probability of damage to the liquid delivery pipeline 4.

[0076] Thus, the present disclosure, by decomposing the extrusion device 2 into the first extrusion device 23 and the second extrusion device 24, can provide space for position adjustment of the liquid delivery pipeline 4 during the assembly process, thereby ensuring the accuracy of the flow rate and flow rate of the liquid delivered by the liquid delivery device, and improving the service life and reliability of the liquid delivery device. At the same time, because the second extrusion device 24 includes at least two sub-extrusion parts 211, the coaxiality of the at least two sub-extrusion parts 211 can be ensured.

[0077] In one embodiment, the first extrusion device 23 may include one sub-extrusion portion 211 , and the second extrusion device 24 may include two sub-extrusion portions 211 .

[0078] In one embodiment of the present disclosure, the second extrusion device 24 may include a first sub-extrusion device 2 and a second sub-extrusion device 2. The first sub-extrusion device 2 may be disposed adjacent to and connected to the first extrusion device 23 along the second direction Y, and a partition 22 may be disposed adjacent to the first sub-extrusion device 2 and the first extrusion device 23. The first sub-extrusion device 2 may include at least one sub-extrusion portion 211.

[0079] The second sub-extrusion device 2 may be located on a side of the first sub-extrusion device 2 facing away from the first extrusion device 23 and may be connected to the first sub-extrusion device 2. In addition, a partition 22 may be provided adjacent to the second sub-extrusion device 2 and the first sub-extrusion device 2, and the second sub-extrusion device 2 may include at least one sub-extrusion portion 211.

[0080] It should be noted that, in this embodiment, the first sub-extrusion device 2 and the second sub-extrusion device 2 are split structures.

[0081] The present disclosure can further optimize the assembly process of the liquid delivery device by decomposing the second extrusion device 24 into the first sub-extrusion device 2 and the second sub-extrusion device 2. That is, when assembling the liquid delivery device, the first extrusion device 23 and the liquid delivery pipeline 4 located between the sub-extrusion portion 211 of the first extrusion device 23 and the housing 1 can be assembled first; and when assembling the first sub-extrusion device 2, the position of the liquid delivery pipeline 4 located between the sub-extrusion portion 211 of the first extrusion device 23 and the housing 1 can be adjusted to ensure the position accuracy of the liquid delivery pipeline 4, thereby ensuring the accuracy of the flow rate and flow rate of the liquid delivered, and reducing the probability of damage to the liquid delivery pipeline 4.

[0082] Moreover, after adjusting the liquid delivery pipeline 4 between the sub-extrusion portion 211 of the first extrusion device 23 and the shell 1, the first sub-extrusion device 2 and the liquid delivery pipeline 4 between the sub-extrusion portion 211 of the first sub-extrusion device 2 and the shell 1 can be assembled; and when assembling the second sub-extrusion device 2, the position of the liquid delivery pipeline 4 between the sub-extrusion portion 211 of the first sub-extrusion device 2 and the shell 1 can be adjusted to ensure the position accuracy of the liquid delivery pipeline 4, thereby ensuring the accuracy of the flow rate and flow rate of the liquid it delivers, and reducing the probability of damage to the liquid delivery pipeline 4.

[0083] After adjusting the liquid delivery pipeline 4 between the sub-extrusion portion 211 of the first sub-extrusion device 2 and the shell 1, the second sub-extrusion device 2 and the liquid delivery pipeline 4 between the sub-extrusion portion 211 of the second sub-extrusion device 2 and the shell 1 can be assembled, and the position of the liquid delivery pipeline 4 between the sub-extrusion portion 211 of the second sub-extrusion device 2 and the shell 1 can be adjusted to ensure the position accuracy of the liquid delivery pipeline 4, thereby ensuring the accuracy of the flow rate and flow rate of the liquid it delivers, and reducing the probability of damage to the liquid delivery pipeline 4.

[0084] Therefore, the present disclosure can provide space for position adjustment of the liquid delivery pipeline 4 located in the second extrusion device 24 during the assembly process by decomposing the second extrusion device 24 into the first sub-extrusion device 2 and the second sub-extrusion device 2, thereby ensuring the accuracy of the flow rate and flow rate of the liquid delivered by the liquid delivery device, and can further improve the service life and reliability of the liquid delivery device.

[0085] In one embodiment, the first extrusion device 23 may include one sub-extrusion portion 211 , the first sub-extrusion device 2 may include one sub-extrusion portion 211 , and the second sub-extrusion device 2 may include one sub-extrusion portion 211 .

[0086] In one embodiment, the first extrusion device 23 and the second extrusion device 24 can be coaxially arranged. In this way, it can be ensured that the extrusion forces applied by the first extrusion device 23 and the second extrusion device 24 to each liquid delivery pipeline 4 are uniform at all times.

[0087] In one embodiment, a partition 22 is provided at each end of the first extrusion device 23 in the second direction Y, and one of the two partitions 22 is located adjacent to the first extrusion device 23 and the second extrusion device 24. Furthermore, the outer diameter of the partition 22 located adjacent to the first extrusion device 23 and the second extrusion device 24 can be larger than the outer diameter of the other partition 22. With this arrangement, the partition 22 located adjacent to the first extrusion device 23 and the second extrusion device 24 can be used to push the liquid delivery pipeline 4 to move during assembly of the liquid delivery device, thereby preventing the liquid delivery pipeline 4 from being squeezed during assembly.

[0088] In one embodiment of the present disclosure, the first extrusion device 23 and the second extrusion device 24 can be manufactured through a molding process. This configuration ensures coaxiality between the first extrusion device 23 and the second extrusion device 24, ensuring uniform extrusion force applied to the liquid delivery pipeline 4 by the first extrusion device 23 and the second extrusion device 24. However, this is not limiting and the first extrusion device 23 and the second extrusion device 24 can also be manufactured through other processes.

[0089] In one embodiment of the present disclosure, the extrusion device 2 can be an integrated structure, that is, the first extrusion device 23 and the second extrusion device 24 can be manufactured through an integrated process, without the need to use other connection methods to connect the first extrusion device 23 and the second extrusion device 24 together. This configuration can improve the coaxiality of the extrusion device 2 compared to the above two embodiments, further ensuring that the extrusion device 2 applies a uniform extrusion force to each liquid delivery pipeline 4.

[0090] In one embodiment of the present disclosure, as shown in Figures 2 to 5 , each sub-extrusion portion 211 may be provided with a partition 22 on both sides in the second direction Y. With this arrangement, the partitions 22 on both sides of each sub-extrusion portion 211 can be used to stop each liquid delivery pipeline 4, preventing the liquid delivery pipeline 4 from being displaced after being extruded and falling off the extrusion device 2.

[0091] The dimension of the sub-extrusion portion 211 along the second direction Y may be larger than the dimension of the liquid delivery pipeline 4 along the second direction Y. This arrangement can leave extra space for the liquid delivery pipeline 4, thereby facilitating adjustment of the position of the liquid delivery pipeline 4 and preventing damage to the liquid delivery pipeline 4 due to friction with the partition 22 during rotation of the extrusion device 2.

[0092] In one embodiment, as shown in Figures 4 and 5, the sub-extrusion portion 211 may include a main body 2111 and a plurality of extrusion rollers 2112. The separator 22 may be located at both ends of the main body 2111 in the second direction Y. The plurality of extrusion rollers 2112 may be arranged around the main body 2111 along the first direction X, and the plurality of extrusion rollers 2112 may be spaced apart along the first direction X. The two ends of the extrusion roller 2112 may be connected to the separator 22 located on both sides of the main body 2111 in the second direction Y, respectively. The present disclosure can utilize the extrusion rollers 2112 to extrude the liquid delivery pipeline 4, and since the extrusion rollers 2112 are spaced apart along the first direction X, a pulsed extrusion force can be applied to the liquid delivery pipeline 4. When the squeezing roller 2112 applies squeezing pressure to the liquid conveying pipeline 4, the liquid in the liquid conveying pipeline 4 can be squeezed to the liquid outlet 43; when the squeezing roller 2112 does not apply squeezing pressure to the liquid conveying pipeline 4, the external liquid can enter the liquid conveying pipeline through the liquid inlet 41 of the liquid conveying pipeline 4, thereby realizing the reciprocating cycle of liquid inlet and outlet.

[0093] In one embodiment, three squeezing rollers 2112 may be provided, and the three squeezing rollers 2112 may be evenly distributed along the first direction X. That is, the angle between any two squeezing rollers 2112 may be 120°.

[0094] In one embodiment of the present disclosure, as shown in Figures 1 to 3, the liquid delivery device may include a liquid input device 5 and a liquid output device 6. At least part of the liquid input device 5 may be located outside the housing 1. The liquid input device 5 may include a first input port 51 and at least three first output ports 52, and each first output port 52 may be connected to each liquid inlet 41 in a one-to-one correspondence. The liquid output device 6 may include at least three water outlets 61. The water outlet 61 may be partially located outside the housing 1. The water outlet 61 may include a second input port 611 and a second output port 612, and each second input port 611 may be connected to each liquid outlet 43 in a one-to-one correspondence.

[0095] For example, three liquid delivery pipelines 4 may be provided. In this case, the liquid input device 5 may include a first input port 51 and three first output ports 52, and the three first output ports 52 may be respectively connected to the liquid inlets 41 of the three liquid delivery pipelines 4. The liquid output device 6 may include three water outlets 61, and the three water outlets 61 may be connected to the liquid outlets 43 of the three liquid delivery pipelines 4.
