A circulation drive mechanism and a refrigeration mechanism are arranged in the fluid-driven main unit, and the refrigerated or heated fluid is transported to the bag of the headgear through the hose by the circulation drive mechanism, and then the fluid is returned to the circulation drive mechanism through the hose to realize fluid circulation.

[0004] In order to realize the circulation of fluid, the existing hot and cold compress device needs two hoses to be connected. The two hoses are arranged in parallel, one for conveying the refrigerated or heated fluid and the other for recovering the fluid in the bag. In view of the above related technologies, the present application provides another medium circulation structure capable of realizing medium circulation. Utility Model Content

[0005] In order to realize the circulation flow of the medium, the present application provides a medium circulation structure, a hot and cold compress host, a hot and cold compress component and a hot and cold compress device.

[0006] The medium circulation structure, hot and cold compress host, hot and cold compress component and hot and cold compress device provided in the present application adopt the following technical solutions:

[0007] In the first aspect, a medium circulation structure includes a circulation joint and an internal pipe, wherein the circulation joint has a circulation chamber for installing the internal pipe, both ends of the internal pipe pass through the circulation chamber, and one end of the internal pipe is connected to the circulation chamber, and the other end extends outside the circulation chamber, the circulation joint has a first through hole and a second through hole connected to the circulation chamber, and the first through hole, the second through hole and the circulation chamber form a flow channel for the medium to flow.

[0008] By adopting the above technical solution, the circulation joint and the internal pipe cooperate to form a circulation structure as a connection structure of two components, wherein the medium in one component is transported to the other structure through the internal pipe, and the transported medium is used in the other structure and then refluxed through the first through hole, the second through hole and the circulation chamber, or the internal pipe is used as a recovery pipe, and the first through hole, the second through hole and the circulation chamber are used as a delivery pipe. The arrangement of the above circulation structure realizes the medium transportation and recovery of the two components. Compared with the circulation structure using two hoses in parallel, the present application can realize circulation by using two hoses in parallel or two hoses in a sleeve at the same time.

[0009] Optionally, the inner diameter of the circulation chamber is larger than the outer diameter of the inner pipe, one end of the inner pipe is provided with a sealing sleeve that is in sealing contact with the inner wall of the circulation chamber, and the other end of the inner pipe is connected to a first pipe.

[0010] By adopting the above technical scheme, a connection method of an internal pipe and a circulation joint is disclosed. The internal pipe is sealed and connected to the circulation joint through a sealing sleeve, and the inner diameter of the circulation chamber is larger than the outer diameter of the internal pipe, so that the medium separated from the internal pipe is only transported in the first through hole, the circulation chamber and the second through hole. The first tube is connected to the internal pipe for extending the first tube for easy connection with the component.

[0011] Optionally, the second through hole is located at the end of the circulation joint, and the circulation joint is provided with a second tube connected to the second through hole, and the second tube is sleeved with the first tube.

[0012] By adopting the above technical solution, an arrangement of the second through hole is disclosed. The second tube is arranged to extend the circulation chamber to facilitate connection with the component. At the same time, the second tube is arranged in the first tube. Compared with the arrangement of two parallel hoses, the medium in the first tube is more stable during transportation and is less affected by the outside world.

[0013] Optionally, first limiting rings are provided at intervals on the outer side wall of the circulation joint along the axial direction, and the first limiting rings are in limiting contact with the second pipe.

[0014] By adopting the above technical solution, after the second pipe is connected to the circulation joint, the connection strength between the circulation joint and the second pipe is improved by setting the first limiting ring, thereby reducing the probability of the second pipe being separated from the circulation joint.

[0015] Optionally, the second tube is filled with a water-permeable layer.

[0016] By adopting the above technical solution, the setting of the permeable layer can support the inner cavity of the second tube sleeved in the first tube. When the first and second tubes for transportation are bent by the outside world, the second tube achieves a supporting effect through the first tube, ensuring that the medium at the bending point of the second tube can flow normally. The support is achieved in the first tube through the permeable layer, which also reduces the probability of a slow flow speed of the medium at the bending point of the first tube.

[0017] Optionally, first limiting rings are provided at intervals on the outer side wall of the circulation joint along the axial direction, and the first limiting rings are in limiting contact with the second pipe.

The first through pipe is inserted into the connecting block to communicate with the internal pipe, and the second through pipe is inserted into the connecting plate to communicate with the second chamber. In specific use, the medium in one component is transported to another component along the first through pipe, the first chamber, the internal pipe and the first pipe in sequence; the medium flows back to the component along the second pipe, the circulation chamber, the second chamber and the second through pipe in sequence.

[0022] By adopting the above technical solution, the connecting block of the medium circulation structure is installed in the shell through the limit groove, the first through pipe is connected to the driving pump, and the second through pipe is connected to the medium storage box. When in use, the heat conduction mechanism heats the medium in the medium storage box, and the medium is transported down to the first through pipe under the action of the driving pump, and then transported to another component. Finally, the refluxed medium flows back to the medium storage box through the second through pipe to complete the circulation of the medium.

[0026] By adopting the above technical solution, the provision of the water-absorbing filling layer can support the medium flow chamber, thereby reducing the probability that the hot and cold compress components are squeezed during use, resulting in slower or no flow of the medium.

[0027] In a fourth aspect, a hot and cold compress device includes a medium circulation structure, a hot and cold compress main unit, and a hot and cold compress component, wherein the hot and cold compress main unit and the hot and cold compress component are connected via the medium circulation structure.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-8 This application is described in further detail.

[0043] The embodiments of the present application disclose a medium circulation structure, a hot and cold compress host, a hot and cold compress component and a hot and cold compress device.

[0044] Embodiment 1:

[0045] Reference Figure 1 and Figure 2The medium circulation structure includes a circulation joint 1, an internal pipe 2, a connecting block 3 and a connecting plate 4. The circulation joint 1 is a cylindrical shell with two ends passing through it as a whole, and there is a circulation chamber 11 inside it for installing the internal pipe 2. Both ends of the internal pipe 2 pass through the circulation joint 1, one end of which is connected to the circulation chamber 11, and the other end extends to the outside of the circulation joint 1. The end fixing sleeve of the internal pipe 2 is provided with a sealing sleeve 21 that is sealed and abutted against the inner wall of the circulation chamber 11, so as to improve the sealing effect of the internal pipe 2 and the circulation joint 1. In other embodiments, the internal pipe 2 can be integrally arranged with the circulation joint 1 to achieve a sealed connection. The medium can be a fluid or a gas, and in this embodiment it is a fluid.

[0046] One end of the inner tube 2 extending out of the circulation joint 1 is connected to a first tube 22, which is used to extend the length of the inner tube 2. In this embodiment, the first tube 22 and the inner tube 2 are integrally arranged. In other embodiments, the inner tube 2 and the first tube 22 can be two sections of hoses sealed and connected.

[0047] The inner diameter of the circulation chamber 11 along the axial direction is larger than the outer diameter of the inner tube 2, and the circulation chamber 11 is provided with a first through hole 12 and a second through hole 13 that are connected to the circulation chamber 11. The first through hole 12, the second through hole 13 and the circulation chamber 11 form a flow channel so that the medium flows out of the first through hole 12 and flows into the second through hole 13, or flows into the first through hole 12 and flows out of the second through hole 13. Among them, the end of the circulation joint 1 corresponding to the sealing sleeve 21 is the reduction end 14, and the outer diameter of the reduction end 14 is smaller than the outer diameter of the first through hole 12 as a whole.

[0048] The first through hole 12 is located on the side wall of the circulation joint 1 close to the sealing sleeve 21, and has two first through holes 12 arranged symmetrically along the axis, and the second through hole 13 is located at the end of the circulation joint 1 away from the sealing sleeve 21. The circulation joint 1 is also provided with a second tube 15 at the second through hole 13, and the second tube 15 is sleeved on the end of the circulation joint 1 and sleeved inside the first tube 22. Among them, the inner cavity of the first tube 22 is also filled with a water-permeable layer 23 along the length direction. The water-permeable layer 23 is made of a fiber material of a water-absorbing material, which can support the inner cavity of the first tube 22, thereby reducing the impact of the first tube 22 being squeezed and causing the conveying medium to flow slowly.

[0049] The outer wall of the circulation joint 1 is evenly spaced along the axial direction with a plurality of first limiting rings 16, and the first limiting rings 16 are integrally arranged with the circulation joint 1. The first limiting rings 16 and the inner wall of the second pipe 15 are in contact with each other to improve the connection strength between the second pipe 15 and the circulation joint 1. The first limiting ring 16 also has a first annular surface 161 inclined inwardly toward the second pipe 15, which is used to improve the sleeve connection efficiency between the circulation joint 1 and the second pipe 15.

[0050] In this embodiment, the second tube 15 serves as a reflux tube, and the inner tube 2 and the first tube 22 serve as delivery tubes. Through the above-mentioned arrangement, the medium transported in the inner tube 2 can be isolated from the outside world to a certain extent through the second tube 15, so that the medium in the inner tube 2 is less affected by the outside temperature, so that the temperature of the medium transported to the application component is always maintained within the temperature range, and the use effect is good.

[0051] In other embodiments, the first through hole 12 and the second through hole 13 may both be located on the side wall of the circulation joint 1. In this case, the second tube 15 and the first tube 22 are two parallel tubes, one of which is used as a delivery tube and the other is a return tube.

The two ends of the first chamber 31 pass through the opposite side end faces of the circulation joint 1. The circulation joint 1 is partially sealed and installed in the first chamber 31, and the other part of it on which the second tube 15 is installed protrudes from the outside of the connecting block 3. The outer wall of the circulation joint 1 is also spaced apart along the axial direction with a second limiting ring 17, and the second limiting ring 17 is used to limit and abut with the inner wall of the first chamber 31, so as to improve the connection strength between the first chamber 31 and the circulation joint 1. The second limiting ring 17 has a second annular surface, and the direction of the second annular surface is opposite to that of the first annular surface 161.

[0053] The second chamber 32 includes a reflux chamber 321 and a reflux channel 322. The reflux chamber 321 is an annular chamber as a whole, and its inner diameter is larger than the outer diameter of the side wall where the first through hole 12 is located. One end of the reflux channel 322 is connected to the reflux chamber 321, and the other end passes through the side wall of the connecting block 3. When the refluxed medium is transported from the second pipe 15 to the circulation chamber 11, it flows out to the reflux chamber 321 along the first through hole 12, and flows out along the reflux channel 322.

[0054] The connecting plate 4 is sealed on one side of the connecting block 3, and a first through pipe 41 and a second through pipe 42 are integrally provided on the connecting plate 4. The first through pipe 41 and the second through pipe 42 are inserted into the connecting block 3, and are respectively connected with the internal pipe 2 and the return channel 322 in the installation chamber.
