Description

A circulating fluid tube Technical Field

[0001] This utility model relates to the field of ice bath liquid circulation, specifically to a circulating liquid pipe. Background Technology

[0002] For the general public, especially athletes, ice bath therapy is an increasingly popular scientific health care method. This therapy is based on physiological responses and can effectively improve athletes' physical recovery efficiency and overall health level. Specifically, ice bath therapy can reduce cell metabolism and blood flow velocity, reduce nerve conduction velocity, reduce muscle spindle activity, and lower blood lactate levels. These physiological responses enable ice bath therapy to prevent delayed onset muscle soreness, prevent muscle damage, promote fatigue recovery, reduce cellular hypoxia damage, relieve pain, and alleviate muscle spasms.

[0003] Traditionally, ice baths involved placing ice cubes inside a tub to lower the water temperature, with people immersing themselves in the cold water. This method was not only cumbersome but also required a large amount of ice, increasing the cost. Therefore, nowadays, most people use ice bath machines for ice bath therapy. Ice bath machines can regulate the temperature of the water in the tub, maintaining it at a constant temperature suitable for ice baths. In a circulating environment, the water in the ice bath continuously flows between the temperature control device and the tub, ensuring that the water temperature remains consistent throughout the entire therapy process.

[0004] However, existing ice bath machines generally adopt a combination design where the bathtub and the chiller are connected by two separate inlet and outlet water pipes. This design not only occupies a lot of space, but also has complicated connections. During use, the two inlet and outlet water pipes are of different lengths and have different connection positions, which makes installation difficult. The inlet and outlet water markings are not clear, which can lead to the inlet and outlet water being connected in reverse. In addition, when not in use, the size and weight of the ice bath machine may become a problem for storage and transportation. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of complicated and difficult connections and large footprint in the prior art by setting up a circulating liquid pipe, thereby reducing the connection structure between the chiller and the bathtub.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model discloses a circulating liquid pipe, including a liquid distributor assembly, a union connector, a jacketed connecting pipe, a return port, a liquid collector, a liquid pump, and an inlet filter cover.

[0008] The liquid separator assembly is connected to the jacketed connecting pipe via a union connector. The other end of the jacketed connecting pipe is connected to the liquid collecting head. The liquid collecting head is connected to one end of the liquid pump, and the other end of the liquid pump is connected to the inlet filter cover.

[0009] The interlayer connecting pipe includes a first liquid inlet pipe and a second liquid return pipe arranged coaxially from the inside to the outside, wherein the first liquid inlet pipe is also connected to a liquid pump, and the second liquid return pipe is also connected to at least one liquid return port provided on the liquid collecting head.

[0010] The length of the interlayer connecting pipe can be selected arbitrarily, and / or the material of the interlayer connecting pipe can be selected arbitrarily according to the liquid being applied;

[0011] The liquid distributor assembly includes a liquid distributor, a through-plate locking nut, a seal, and a union nut.

[0012] As a further improvement, the return port includes one or more openings evenly distributed on the circumferential plane of the liquid collecting head, with the outer edge of each return port tangent to the edge of the liquid collecting head and the inner edge transitioning to the center of the liquid collecting head through a chamfer, forming a radial channel.

[0013] As a further improvement, the central axes of the first inlet pipe and the second return pipe coincide, wherein the first inlet pipe is located inside the second return pipe;

[0014] The outer wall of the second return pipe is fitted with a heat insulation layer.

[0015] As a further improvement, the liquid separator includes an inlet pipe and an outlet pipe, and the union connector includes an inlet connector and an outlet connector;

[0016] A sealing element is provided between the liquid inlet pipe and the liquid inlet connector, and a sealing element is provided between the liquid outlet pipe and the liquid outlet connector;

[0017] The liquid separator assembly is threadedly connected to the union nut.

[0018] As a further improvement, the seal is a coaxial double-ring gasket.

[0019] As a further improvement, the liquid inlet connector is connected to the first liquid inlet pipe, and the liquid outlet connector is connected to the second liquid return pipe.

[0022] As a further improvement, one end of the interlayer connecting tube is connected to the liquid separator assembly, and the other end is also connected to the liquid separator assembly.

[0023] As a further improvement, the liquid pump is embedded in the liquid collection head, and the liquid collection head is threadedly connected to the inlet filter cover.

[0024] Compared with the prior art, this utility model achieves the following technical effects:

[0025] The circulating liquid pipe of this invention can simultaneously perform the functions of liquid delivery and liquid return. The cooled liquid can be transported to the container through the inlet pipe and the second return pipe in the liquid distributor. The liquid in the container is then transported back to the refrigeration equipment through the first inlet pipe and the outlet pipe for further cooling. The entire circulation process not only ensures the efficiency of liquid delivery and return but also ensures the stability of the cooling effect. At the same time, the high integration of the entire device achieves space saving.

[0026] The circulating liquid pipe of this utility model enables circulation operation by reserving only one liquid distributor assembly between the chiller and the container. This not only simplifies the structure of the circulation system and reduces the difficulty of installation and maintenance, but also allows the design to meet the needs of multiple different scenarios, demonstrating extremely high adaptability.

[0027] The circulating liquid pipe of this invention is equipped with multiple return ports. While ensuring the cooling effect, the return ports are designed tangentially along the axis, which allows the cold water injected into the container to form strong turbulence. This effectively promotes the uniform mixing between the cold water and the uncooled water, thereby greatly improving the cooling efficiency and uniformity and ensuring the consistency of the water temperature in the container.

[0028] The various components of the circulating fluid pipe of this utility model are simply connected, making it easy for users to replace or repair when needed, greatly reducing the cost of use and the difficulty of maintenance.

[0029] Compared with existing structures, the ice bath machine of this utility model simplifies the structure of the entire device. By installing the chiller on the bath cover, it not only reduces the space occupied by the entire device, but also makes the device more compact and beautiful. This not only improves the portability of the device, but also makes it possible to apply it in limited spaces, thus broadening the market prospects of the device.

[0030] Compared with existing structures, the ice bath machine of this utility model simplifies the structure of the entire device. By installing the liquid separator assembly on the chiller and the bathtub respectively, the combination structure of the two separate inlet and outlet water pipes is simplified. The installation process is simple, efficient and foolproof. Attached Figure Description

[0039] The embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. Rather, the embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0041] It should be noted in this embodiment that the structure of a common ice bath machine in the prior art, as shown in Figure 1, generally involves a cooling fan connected to one end of the bathtub via a circulation mechanism. This circulation mechanism includes a return pipe and a supply pipe. Therefore, during actual installation, two sets of connectors, pipes, and other parts are required. Furthermore, if filters and liquid pumps are to be installed, separate interfaces need to be reserved on the pipes. In summary, the internal structure of the entire circulation mechanism is cumbersome, subsequent maintenance is troublesome, and the entire ice bath machine occupies a large space. The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] To address the aforementioned issues, as shown in Figure 2, this embodiment provides a circulating liquid pipe, including a liquid distributor assembly, a union connector 3, a jacketed connecting pipe 4, a return port 5, a liquid collecting head 8, a liquid pump 9, and an inlet filter cover 10; in this embodiment, the liquid distributor assembly includes a liquid distributor 1, a through-plate locking nut 2, a sealing element 6, and a union connector nut 7.

[0044] In this embodiment, the liquid separator 1 can regulate the flow direction of the fluid. The liquid separator 1 is connected to the union connector 3 by the union nut 7. The liquid separator 1 includes an inlet pipe 1.1 and an outlet pipe 1.2. The union connector 3 includes an inlet connector 3.1 and an outlet connector 3.2. The inlet pipe 1.1 is aligned and connected to the inlet connector 3.1, and the outlet pipe 1.2 is aligned and connected to the outlet connector 3.2. By rotating the union nut 7, the liquid separator 1 and the union connector 3 can be tightened or loosened, providing the function of adjusting, disassembling and reinstalling the liquid separator 1, improving flexibility. The other end of the union connector 3 is connected to the interlayer connecting pipe 4.

[0045] As shown in Figure 7, in this embodiment, the union connector 3 is cylindrical in shape. The union connector 3 includes an inlet connector 3.1 and an outlet connector 3.2. Therefore, during assembly, the inlet connector 3.1 is aligned and connected with the first return pipe 4.1 in the interlayer connecting pipe 4, and the outlet connector 3.2 is aligned and connected with the second return pipe 4.2 in the interlayer connecting pipe 4, thereby completing the connection between the union connector 3 and the interlayer connecting pipe 4. In this embodiment, an adhesive bonding method is preferred, but it is not limited to this. Depending on the application scenario, threaded or other commonly used methods can also be selected for connection.

[0046] In this embodiment, a sealing element 6 is also provided between the liquid dispensing head 1 and the union connector 3. The sealing element ensures that the connection between the liquid dispensing head 1 and the union connector 3 can maintain sufficient pressure. The sealing element 6 in this embodiment is preferably a coaxial double ring gasket, but it is not limited to this. Other sealing elements with different structures can also be selected according to the usage scenario.

[0047] As shown in Figure 3, the left end of the liquid separator 1 in this embodiment is an inlet pipe 1.1, and the right end is an outlet pipe 1.2. The outlet pipe 1.2 is connected to the inlet end of the refrigeration equipment, and the inlet pipe 1.1 is connected to the output end of the refrigeration equipment. The liquid separator 1 in this embodiment has a compact and reasonable structure. Compared with the pipes in the prior art, it not only reduces the number and length of pipe connections and the complexity of the pipes, but also facilitates installation and subsequent maintenance by operators. According to the flow arrows of the fluid in Figure 3, the blue arrows indicate the path of the uncirculated water. The uncirculated water is pumped into the first inlet pipe 4.1 by the liquid pump 9, and after passing through the first inlet pipe 4.1, it enters the refrigeration equipment for treatment through the outlet pipe 1.2. The red arrows indicate the path of the circulated water. The circulated water enters from the inlet pipe 1.1, enters the second return pipe 4.2, and then enters the container through the return port 5, realizing the entire circulation process.

[0048] As shown in Figures 3 and 4, the sandwich connecting pipe 4 in this embodiment includes a first inlet pipe 4.1 and a second return pipe 4.2. The sandwich connecting pipe 4 is cylindrical in shape. The first inlet pipe 4.1 is located at the center of the sandwich connecting pipe 4, and the second return pipe 4.2 is located between the first inlet pipe 4.1 and the edge of the sandwich connecting pipe 4. The first inlet pipe 4.1 and the second return pipe 4.2 are coaxially arranged. The sandwich connecting pipe 4 in this embodiment can be selected with appropriate length according to different application scenarios. At the same time, the sandwich connecting pipe 4 can be selected with appropriate material according to different application scenarios.

[0049] As shown in Figures 2 and 3, the liquid collecting head 8 of this embodiment has an internal space for accommodating the liquid pump 9. As shown, the top of the liquid collecting head 8 has a protruding structure, which is connected to the bottom of the liquid collecting head 8 through a transition surface. The center of the protruding structure has a first opening, which connects the first inlet pipe 4.1 to the output end of the liquid pump 9. A second opening is provided around the first opening, which connects the second return pipe 4.2 to the outlet 5. As shown in Figure 2, in this embodiment, the liquids in the first inlet pipe 4.1 and the second return pipe 4.2 will not come into contact with each other during use, thus achieving stability in liquid return and liquid delivery.

[0050] As shown in Figure 5, the bottom of the protruding structure of the liquid collecting head 8 is evenly provided with multiple return ports 5. In this embodiment, four return ports 5 are preferably provided, but it is not limited to this. The number of return ports 5 can be increased or decreased according to actual use needs. The opening of the return port 5 has a rectangular outline, and the outer edge is tangent to the edge of the liquid collecting head 8. The inner edge transitions to the center of the liquid collecting head 8 through a rounded corner, forming a radial channel. When the return ports 5 are arranged tangentially along the axis, the injected circulating water will flow along the tangential direction at the moment of contact with the container, instead of being injected directly vertically downward or horizontally. This flow mode will generate tangential force, causing the liquid to rotate in the container and form turbulence, thereby achieving uniform mixing of circulating water and non-circulating water.

[0051] In this embodiment, the liquid pump 9 is also provided with a filter element 11 at the bottom. The filter element 11 is specifically located between the liquid inlet filter cover 10 and the liquid pump 9. The filter element 11 can filter the liquid before it enters the liquid pump 9, effectively removing impurities, particles and suspended matter in the liquid, and ensuring the cleanliness of the liquid inside the liquid pump 9 and the subsequent liquid.

[0052] In this embodiment, the liquid dispensing head 1 is connected to the equipment housing through the through-plate locking nut 2. Specifically, the liquid dispensing head 1 is passed through the equipment housing and then locked and supported by the through-plate locking nut 2.

[0053] In this embodiment, after the device is installed, ensure that the liquid inlet filter cover 10 is immersed in the container. At this time, the liquid in the container will pass through the liquid inlet filter cover 10 and the filter element 11 and enter the liquid pump 9. Under the action of the liquid pump 9, the liquid is driven through the first liquid inlet pipe 4.1 and enters the refrigeration equipment for processing through the liquid outlet pipe 1.2 of the liquid separator 1. The processed liquid passes through the liquid inlet pipe 1.1 of the liquid separator 1 and the second liquid return pipe 4.2 and is injected back into the container from the liquid return port 5 to realize the flow and circulation of the liquid.

[0054] It should be noted that the circulating liquid pipe in this embodiment can be applied to various circulating systems such as refrigeration, cleaning, lubrication, and sewage treatment.
