DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figures 1 to 11 This embodiment provides a flow regulator 100, including a water outlet block 1 and a sliding docking member 2.

[0034] A plurality of venturi tubes 11 are provided inside the water outlet block 1 (the venturi tubes 11 are inner holes of the water outlet block 1), and the water outlets of the plurality of venturi tubes 11 are located on one end surface of the water outlet block 1. The sliding docking member 2 is slidably mounted on the end surface. The sliding docking member 2 is provided with a water hole 211, and the water hole 211 changes position with the sliding of the sliding docking member 2 to adjust the total flow area of ​​the venturi tube 11 directly facing the water hole 211.

[0035] The working principle of the flow regulator 100 of this embodiment is as follows:

[0036] Different use environments have different water pressure conditions. For use environments with low water pressure, the cavitation effect cannot meet the use requirements because the flow rate is insufficient. This embodiment can adjust the actual flow amount of the venturi tube 11 by changing the relative position of the sliding docking member 2 and the water outlet block 1, thereby increasing the flow rate, so that users can also obtain good cavitation effects in low water pressure use environments. In addition, the flow regulator 100 can be used with various types of water outlet equipment, such as shower heads, and has a wide range of applications.

[0037] As a possible example, in this embodiment, the flow regulator 100 further includes a water outlet pipe 3, and the water outlet block 1 is fixed in the water outlet pipe 3. Threads are provided at both ends of the water outlet pipe 3 to achieve quick connection with adjacent structures.

[0038] As a possible example, in this embodiment, a first axial slot 31 is provided on the inner side of the water outlet pipe 3, and an axial plug block 12 is provided on the water outlet block 1, and the axial plug block 12 is connected to the first axial slot 31 by sliding insertion. The circumferential position of the water outlet block 1 can be limited by the mutual limitation of the first axial slot 31 and the axial plug block 12. The pressure of the sliding docking member 2 on the water outlet block 1 makes the end of the axial plug block 12 abut against the end of the first axial slot 31, so that the axial position of the water outlet block 1 can be limited.

[0039] As a possible example, in this embodiment, a circumferential groove 32 is provided on the outer side of the water outlet pipe 3, and a latch 4 is provided on the water outlet block 1, and the latch 4 passes through the circumferential groove 32. The water outlets of the multiple Venturi tubes 11 are unevenly distributed along the circumferential direction of the water outlet block 1, so that when the latch 4 moves the sliding docking member 2, the number of Venturi tubes 11 facing the water hole 211 can be adjusted, and then the total flow area of ​​the Venturi tubes 11 facing the water hole 211 can be adjusted. By moving the latch 4, the latch 4 slides along the circumferential groove 32, so that the sliding docking member 2 can rotate relative to the water outlet block 1. The latch 4 is preferably arranged along the radial direction of the water outlet pipe 3, and the water hole 211 preferably includes an arc hole with the axis of the sliding docking member 2 as the center.

[0040] In this embodiment, the water holes 211 include not only the arc holes mentioned above, but also a circular hole with the axis of the sliding docking member 2 as the center. When the sliding docking member 2 rotates, the number and total flow area of ​​the venturi tubes 11 opposite to the circular holes remain unchanged, while the number and total flow area of ​​the venturi tubes 11 opposite to the arc holes change.

[0041] However, the actual implementation is not limited thereto. For example, in addition to the above-mentioned rotation of the sliding docking member 2 relative to the water outlet block 1, the sliding docking member 2 can also be translated relative to the water outlet block 1, and the total flow area of ​​the outlet of the venturi tube 11 relative to the water hole 211 can also be adjusted.

[0042] As a possible example, in this embodiment, the flow regulator 100 further includes a circumferential slip ring 5, which is circumferentially slidably sleeved on the outside of the water outlet pipe 3, and one end of the latch 4 extending out of the circumferential slide groove 32 is connected to the circumferential slip ring 5, so as to move the latch 4 through the circumferential slip ring 5. In order to facilitate installation, a second axial slot 51 is provided on the inner side of the circumferential slip ring 5 in this embodiment. When the circumferential slip ring 5 is slid along the axial direction of the water outlet pipe 3, the latch 4 slides into the second axial slot 51. A limiting shoulder for abutting against the circumferential slip ring 5 can be provided on the outer side of the water outlet pipe 3 to achieve the positioning of the circumferential slip ring 5.

[0043] As a possible example, in this embodiment, the flow regulator 100 also includes a butt joint pipe 6, which is threadedly connected to the water outlet pipe 3. The end of the sliding butt joint 2 facing away from the water outlet block 1 is butt jointed with the butt joint pipe 6 to guide the water flow passing through the sliding butt joint 2 through the butt joint pipe 6. The butt joint pipe 6 applies an axial thrust toward the water outlet block 1 to the sliding butt joint 2. A slideway for the circumferential sliding ring 5 to slide along the circumferential direction is formed between the end of the butt joint pipe 6 and the limiting shoulder of the water outlet pipe 3. Butt joint here refers to direct or indirect contact between the two to achieve conduction of the liquid flow.

[0044] As a possible example, in this embodiment, the butt joint pipe 6 includes an outer pipe 61, an inner pipe 62, an annular portion and a connecting pipe 63. The ends of the outer pipe 61 and the inner pipe 62 are both connected to the first side of the annular portion, and the end of the connecting pipe 63 is connected to the second side of the annular portion. The outer pipe 61 is threadedly connected to the water outlet pipe 3, and the inner pipe 62 is butted against the sliding butt joint 2 and applies axial pressure to the sliding butt joint 2. The sliding butt joint 2 includes a plate 21 and a pipe 22, the plate 21 is connected to the pipe 22, the water hole 211 is located on the plate 21 and directly opposite to the pipe 22, and the pipe 22 is located between the outer pipe 61 and the inner pipe 62.

[0045] As a possible example, in this embodiment, sealing rings are provided between the pipe fitting 22 and the inner tube 62 of the sliding docking member 2, between the pipe fitting 22 and the outer tube 61 of the sliding docking member 2, and between the water outlet block 1 and the water outlet pipe 3. The sealing ring between the pipe fitting 22 and the inner tube 62 of the sliding docking member 2 can transmit axial force, and the axial sides of the sealing ring are positioned by the positioning shoulder on the inner side of the pipe fitting 22 and the positioning shoulder on the outer side of the inner tube 62, respectively.

[0046] As a possible example, in this embodiment, the flow regulator 100 also includes a sealing mesh 7, and an embedded groove 13 corresponding to the sealing mesh 7 is provided on the end surface of the water outlet block 1, and the sealing mesh 7 is embedded in the embedded groove 13. The sealing mesh 7 has a plurality of mesh holes 71, and the plurality of mesh holes 71 separate the water outlets of the plurality of venturi tubes 11. One side of the sealing mesh 7 is tightly against the water outlet block 1, and the other side of the sealing mesh 7 is in sliding contact with the plate 21 of the sliding docking member 2, so that a sealed cavity is formed in the mesh holes 71. When the liquid flows through the mesh holes 71, due to the squeezing of the sealing mesh 7 by the water outlet block 1 and the sliding docking member 2, the liquid flow will not leak into the gap between the water outlet block 1 and the sealing mesh 7 or the gap between the sliding docking member 2 and the sealing mesh 7.

[0047] This embodiment also provides a cleaning device, including the above-mentioned flow regulator 100. There are many types of cleaning devices, and those skilled in the art can choose according to actual needs. For example, the cleaning device can be a bathing device or a washing device (not limited thereto), and the above-mentioned flow regulator 100 can be used on the infusion pipeline of the bathing device or the washing device.

[0048] Since the cleaning device includes the above-mentioned flow regulator 100, it also has the above-mentioned advantages of the flow regulator 100, which will not be described in detail here.

[0049] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
