[0025] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0026] refer to Figure 1 and Figure 2This embodiment provides a water circulation pipeline 1 and a control box 100, wherein the water circulation pipeline 1 is disposed in the control box 100. The water circulation pipeline 1 includes an interface pipeline 11 and a pipeline body 12, and the water circulation pipeline 1 can be connected to a pool body through the interface pipeline 11.

[0027] Specifically, refer to Figure 2 and Figure 3 The interface pipeline 11 includes a first pipeline 111 and a second pipeline 112. The first pipeline 111 is provided with a water inlet 111a, and the second pipeline 112 is provided with a water outlet 112a. The water inlet 111a and the water outlet 112a are respectively used to connect to the pool body. However, the present invention is not limited thereto. In other embodiments, the first pipeline may be provided with a water outlet, and the second pipeline may be provided with a water inlet.

[0028] The pipeline body 12 has a third pipeline 121, and the third pipeline 121 has two ports, namely a first port 121a and a second port 121b, wherein the first port 121a is connected to the first pipeline 111, and the second port 121b is connected to the second pipeline 112, so that the first pipeline 111, the second pipeline 112 and the third pipeline 121 can be connected in sequence to form a water circulation pipeline 1. In the working state, the water in the pool body can flow into the first pipeline 111 through the water inlet 111a, and then pass through the first pipeline 111, the second pipeline 112, and the third pipeline 121 in sequence, and finally flow back to the pool body from the water outlet 112a.

[0029] In this embodiment, the second pipeline 112 is sleeved in the first pipeline 111. In other words, the interface pipeline 11 of this embodiment is a pipe-in-pipe structure, and the water inlet pipe and the water outlet pipe are combined into one, so that, compared with the situation in which the water inlet pipe and the water outlet pipe are designed separately in the prior art, the volume of the water circulation pipeline 1 can be effectively reduced, thereby reducing the volume of the control box 100. In addition, through the water circulation pipeline 1 provided by this embodiment, only one water channel interface is required on the water pool body, and there is no need to set two interfaces as in the prior art, thereby simplifying the design of the water pool body and facilitating the connection between the control box 100 and the water pool body.

[0030] refer to Figure 2 and Figure 3In this embodiment, the first pipeline 111 and the second pipeline 112 are both round tubes, and the first pipeline 111 and the second pipeline 112 are coaxially arranged. After such arrangement, the interface pipeline 11 can be conveniently connected to the pipeline body 12. Furthermore, the pipeline body 12 is located on one axial side of the interface pipeline 11. When the water circulation pipeline 1 is installed on the control box 100, the pipeline body 12 is located inside the control box 100. The exposed part of the water circulation pipeline 1 has only one interface pipeline 11. Compared with the prior art having two interfaces (the water inlet interface and the water outlet interface), the appearance of the control box 100 can be simple and beautiful.

[0031] refer to Figure 3 and Figure 4 A first screw-on portion 111b is provided at one end of the first pipeline 111 axially close to the pipeline body 12, and a second screw-on portion 12a matching the first screw-on portion 111b is provided on the pipeline body 12. In other words, the first screw-on portion 111b and the second screw-on portion 12a are screwed together to realize the connection between the first pipeline 111 and the pipeline body 12.

[0032] A first engaging portion 112b is provided at one end of the second pipeline 112 axially close to the pipeline body 12, and a second engaging portion 12b matching the first engaging portion 112b is provided on the pipeline body 12. In this embodiment, the first engaging portion 112b is an annular groove, and the second engaging portion 12b is an annular projection, which is embedded in the annular groove, so as to achieve the connection between the second pipeline 112 and the pipeline body 12. In other embodiments, the first engaging portion can be set as an annular projection, and the second engaging portion can be set as an annular groove, as long as the connection between the second pipeline and the pipeline body can be achieved.

[0033] The annular groove is coaxially arranged with the first screw-on portion 111b. Thus, when the first screw-on portion 111b is screwed with the second screw-on portion 12a (i.e., the first pipeline 111 is connected with the pipeline body 12), the annular groove and the annular projection are exactly engaged with each other (i.e., the second pipeline 112 is connected with the pipeline body 12).

[0034] In this embodiment, a radial gap is provided between the annular groove and the annular projection. It should be noted that the radial direction is the radial direction of the second pipeline 112. In this way, during the screwing process of the first screwing part 111b and the second screwing part 12a, there is no friction surface between the second pipeline 112 and the pipeline body 12, which can facilitate the assembly between the interface pipeline 11 and the pipeline body 12. Along the axial direction of the second pipeline 112, a sealing ring 113 is provided between the annular groove and the annular projection. During the screwing process of the first screwing part 111b and the second screwing part 12a, a reliable seal can be achieved by pressing the sealing ring 113.

[0035] refer to Figure 3and Figure 4 The first port 121a and the second port 121b of the pipe body 12 are both located at one end of the pipe body 12 close to the interface pipe 11. Specifically, the second screwing portion 12a is arranged around the first port 121a, and the second clamping portion 12b is arranged around the second port 121b. It can be understood that, viewed along the axial direction of the interface pipe 11, the second port 121b is located inside the first port 121a.

[0036] refer to Figure 2 and Figure 3 , a through hole is provided on the peripheral wall of the first pipeline 111, which is equivalent to that the through hole forms the water inlet 111a of the first pipeline 111. Optionally, there are multiple through holes, and the multiple through holes are regularly arranged on the peripheral wall of the first pipeline 111 to make the water flow uniform. Further, along the axial direction of the interface pipeline 11, an annular end plate 114 is provided at one end of the interface pipeline 11 away from the pipeline body 12, and the annular end plate 114 is used to close the radial gap between the first pipeline 111 and the second pipeline 112. It is equivalent to that at the other end of the interface pipeline 11 away from the pipeline body 12, the first pipeline 111 and the second pipeline 112 are isolated from each other by the annular end plate 114, and the end of the second pipeline 112 away from the pipeline body 12 forms the water outlet 112a of the second pipeline 112.

[0037] refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the pipeline body 12 includes a flow dividing section 122 and a main section 123, and the flow dividing section 122 includes a shell 124 and an inner tube 125 disposed in the shell 124. The shell 124 has a first opening 124a and a second opening 124b, wherein the first opening 124a of the shell 124 forms a first port 121a of the flow dividing section 122, which is communicated with the first pipeline 111, and the second opening 124b of the shell 124 is communicated with one end of the main section 123; one end of the inner tube 125 forms a second port 121b of the flow dividing section 122, which is communicated with the second pipeline 112, and the other end of the inner tube 125 is communicated with the other end of the main section 123. Thus, the cavity between the shell 124 and the inner tube 125, the main section 123, and the inner tube 125 are sequentially communicated, thereby forming a third pipeline 121.

[0038] Further, the first opening 124a and the second opening 124b are provided on two opposite side walls of the outer shell 124, so that after the water in the first pipeline 111 flows to the diverter section 122, it flows from the left side wall to the right side wall of the diverter section 122. Further, the inner tube 125 is an arc-shaped curved tube, and one port of the inner tube 125 is formed on the bottom wall of the outer shell 124, so that the water in the inner tube 125 flows from the bottom wall of the diverter section 122 to the left side wall, and then flows into the second pipeline 112.

[0039] Optionally, refer to Figure 3 The diversion section 122 includes a main body and a cover body that are detachably connected to facilitate manufacturing and assembly.

[0040] In this embodiment, the pipeline body 12 includes a U-shaped section 126, and a heating device 13 (for example, a PTC heater) is provided on the U-shaped section 126 to heat the water flow flowing into the water circulation pipeline 1. In addition, the heating device 13 is arranged on the U-shaped section 126, so that the bidirectional water flow can be heated at the same time, which is conducive to improving the heating efficiency.

[0041] refer to Figure 3 In this embodiment, a filter pump 14 is further provided in the pipeline body 12, which can not only filter the water flow in the pipeline, but also be used to limit the flow direction of the water flow. In this embodiment, the filter pump 14 is configured to make the water flow direction be the first pipeline 111 → the third pipeline 121 → the second pipeline 112 (such as Figure 3 As shown by the arrow direction). It can be understood that in another embodiment, by reversing the filter pump 14, the water flow direction can be the second pipeline 112 → the third pipeline 121 → the first pipeline 111 (corresponding to the above-mentioned "in other embodiments, the first pipeline is provided with a water outlet, and the second pipeline is provided with a water inlet"). In addition, a flow switch 15 is also provided in the pipeline body 12.

[0042] This embodiment also provides a massage pool (not shown), including a pool body and a control box 100 provided in an embodiment of the present invention, wherein the interface pipeline 11 of the water circulation pipeline 1 is connected to the pool body.

[0043] In summary, the above embodiments provided by the present invention are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
