Description

Technical Field

[0001] The utility model relates to the technical field of cold compress, in particular to a cold compress instrument. Background Art

[0002] With the development of modern technology, people have found that after strenuous exercise or long-distance running, the body needs time to recover, and a technology that can promote the recovery of body cells is cold compress therapy. This therapy is increasingly favored by athletes, fitness enthusiasts, and even health consumers who pursue rapid relief of inflammation and discomfort.

[0003] Cold water compress treatment is an effective method to relieve muscle and joint inflammation, pain and edema, especially after strenuous exercise. Cold water will constrict blood vessels, limit blood flow to the affected area, and reduce inflammation. Low-temperature cold water compress can also paralyze nerve endings, helping to relieve pain and discomfort and remove lactic acid. As is well known, lactic acid is a metabolic waste. Especially after intense exercise, lactic acid will accumulate in muscles during exercise and may cause discomfort and fatigue. Therefore, in view of these situations, the development of cryotherapy is imperative.

[0004] Currently, there are generally two types of cryotherapy for human body repair. One is cryogenic treatment method, and the other is treatment using a cold compress instrument.

[0005] For the treatment using a cold compress instrument, mainly the refrigerant inside is compressed by a compressor to increase temperature, pressure and form a gas state and enter the condenser. The heat of the refrigerant is released in the form of air cooling to form a low-temperature and high-pressure liquid, which enters the evaporator after passing through the capillary tube. The evaporator exchanges heat with the external cold compress module, and the refrigerant after absorbing heat vaporizes and returns to the compressor for the next cycle. The compression type chiller has the characteristics of high precision, high refrigeration efficiency, reliable performance and long service life, and can provide a suitable temperature for the user to quickly cool the part to be cooled.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0034] As Figures 1 - 4 shown, a cold compress device includes a housing 10, a water tank assembly, and a heat exchanger 40. An installation cavity is provided inside the housing 10, and a cold compress component is provided outside the housing 10. The water tank assembly includes a water tank 20 and a water pump 30. The water tank 20 and the water pump 30 are both installed in the installation cavity. A return water interface and a water outlet interface are provided on the water tank 20. One end of the cold compress component is communicated with the water outlet interface through a cold water pipe. When the water pump 30 works, it can guide the water in the water tank 20 to flow. The power provided by the water pump 30 can make the cold water in the water tank 20 be guided to the cold water pipe through the water outlet interface and then be guided to the cold compress component through the cold water pipe.

[0035] Specifically, the heat exchanger 40 includes a first heat exchange tube and a second heat exchange tube, and the first heat exchange tube and the second heat exchange tube can exchange heat with each other. One end of the first heat exchange tube is communicated with the return water interface of the water tank 20, and the other end of the first heat exchange tube is communicated with the other end of the cold compress component.

[0036] In addition, a refrigeration component is installed in the installation cavity; the refrigeration component includes a compressor 50, a condenser, a dryer filter, and a capillary tube. The outlet of the compressor 50 is communicated with the inlet of the condenser, the outlet of the condenser is communicated with the inlet of the dryer filter, the outlet of the dryer filter is communicated with one end of the capillary tube, and the other end of the capillary tube is communicated with one end of the second heat exchange tube. The other end of the second heat exchange tube is communicated with the inlet of the compressor 50.

[0037] Based on the above structure, when using the cold compress device of the present utility model, during cold compress, the compressor 50 is connected to the condenser, the condenser is connected to the dryer filter, the dryer filter is connected to the capillary copper tube, and the capillary tube is then connected and conducted to one end of the second heat exchange tube of the heat exchanger 40. The other end of the heat exchange tube is connected and conducted to the compressor 50 to form a refrigerant closed loop, and the refrigerant circulates in the closed loop.

[0038] In addition, the water outlet interface on the water tank 20 is communicated with one end of the cold water pipe, the other end of the cold water pipe is communicated to the cold compress component, the cold compress component is communicated to one end of the first heat exchange tube through the return water pipe, and the other end of the first heat exchange tube is communicated with the water return interface of the water tank, so that a water circulation loop can be formed. And the water circulation loop and the refrigerant closed loop can conduct heat exchange.

[0039] In the refrigeration system, under the action of the compressor 50, the refrigerant circulates between the compressor 50, the condenser, the dryer filter, the capillary tube and the heat exchange tube in the water tank 20. The compressor 50 compresses the low-temperature and low-pressure refrigerant into high-temperature and high-pressure steam. In the condenser, the heat of the gaseous refrigerant is dissipated to the environment, and thus it condenses into low-temperature and high-pressure liquid. The dryer filter filters the moisture and impurities in the refrigerant to protect the refrigeration module. And the capillary tube reduces the pressure of the low-temperature and high-pressure liquid refrigerant to prepare for evaporation and enters the second heat exchange tube. Here, due to the sudden increase in space, the liquid refrigerant will quickly evaporate into gas, and at the same time absorb a large amount of heat, and conduct heat exchange with the water in the first heat exchange tube. The cooling water in the first heat exchange tube flows through the water return interface of the water tank 20 to the water tank 20, and the water tank 20 stores the cooling water and flows through the water outlet interface to the cold compress component.

[0040] In this way, the cold water continuously flows out from the internal refrigeration system to the cold compress component. After the cold compress component contacts the part of the human body that needs to be cooled, it takes away its heat, so as to achieve the purpose of cooling.

[0041] In addition, the water in the water tank enters the cold compress component of the cold compress device through the water outlet interface. After the cold water of the cold compress component is cooled, it enters the first heat exchange tube of the heat exchanger. After the first heat exchange tube and the second heat exchange tube conduct heat exchange, the water in the first heat exchange tube becomes cold water and then flows through the water return interface of the water tank to be stored in the water tank, and then is led out to the cold compress component. In this way, the combination of the water tank and the heat exchanger ensures that the water tank capacity can provide sufficient cold water to the cold compress component for cooling, and the cooling capacity is sufficient to improve the cooling efficiency of the cold compress component.

[0042] And under the action of the water pump 30, the water flow of the cold compress component flows through the part of the human body that needs to be cooled in sequence and then returns to the water tank 20 for the next cycle. During this process, the water flow continuously takes the heat generated by the part of the human body that needs to be cooled to the inside of the cold compress device to conduct heat exchange with the heat exchanger 40.

[0043] The refrigeration process of the whole set of equipment is as follows: The external cold compress component of the cold compress instrument is worn on the part of the human body that needs to be cooled, and then the heat is transferred to the water flowing through the cold compress component in a cycle. The water flow takes the heat to the heat exchanger 40 and transfers it to the refrigerant. The refrigerant takes the heat to the condenser and finally dissipates it into the environment.

[0044] It should be noted that the above-mentioned cold compress component is a commonly used cold compress component in existing cold compress instruments, and the capillary tube is specifically a capillary copper tube in the prior art. The compressor 50 is a micro-adjustable direct-current compressor 50; and the above-mentioned compressor 50, drying filter and capillary copper tube are all commonly used devices for refrigeration in the prior art, and their specific working principles and structures do not belong to the technical content to be protected by this application, so they will not be elaborated in detail here.

[0045] Furthermore, a heating component is provided in the water tank 20 of this embodiment. The heating component can heat the water in the water tank 20. Specifically, the above-mentioned heating component is a heating rod, and it can also be realized by a heating coil or a heating resistor, etc.

[0046] When the water temperature needs to be increased, the water in the water tank 20 can be heated by the heating rod, which plays a role in heating up. Specifically, the user can control the water temperature in the water tank 20 according to the actual required cooling water temperature. The heating rod heating method plays a role in temperature compensation for the water temperature in the water tank 20 and plays an auxiliary role in precise temperature control.

[0047] Specifically, a temperature detector can also be set in the water tank 20. The temperature detector can be realized by a temperature sensor. The water temperature in the water tank 20 can be detected through the temperature detector. When the water temperature detected by the temperature detector is higher than the set temperature, the rotation speed of the compressor 50 increases, the refrigeration capacity increases, and the water temperature decreases; when the water temperature detected by the temperature detector is lower than the set temperature, the rotation speed of the compressor 50 decreases, the refrigeration capacity decreases, and the water temperature increases.

[0048] Furthermore, a flow meter is provided at the return water interface. The flow meter is used to detect the water flow introduced at the return water interface. In this way, the flow into the water tank 20 can be monitored through the flow meter. At the same time, a water level gauge is provided in the water tank 20; the water level gauge is used to detect the water level in the water tank 20. The water level in the water tank 20 is monitored through the water level gauge, which plays an automatic protection role when the working water level is too low and can facilitate timely water replenishment. The water pump 30 can be started and stopped according to the detection results of the flow meter and the water level gauge, so that the water volume and water level in the water tank 20 can be better controlled.

[0049] Of course, a drain interface can also be provided at the bottom of the water tank 20. It is connected to the drain pipe through the drain interface and can be used to drain the water in the water tank 20, which is convenient for regular cleaning.

[0050] Furthermore, a display screen 11 is provided on the casing 10; a controller 70 is provided in the installation cavity; the controller 70 is electrically connected to the temperature detector, flow meter, water level gauge, compressor 50, water pump 30, and display screen 11. Users can set the target water temperature according to their own needs through the control of the display screen 11. The temperature sensor transmits the collected temperature value to the controller 70, and the controller 70 adjusts the start / stop and speed of the compressor 50 according to the relationship between the real-time water temperature and the set temperature: when the water temperature is higher than the set temperature, the speed of the compressor 50 increases, the refrigerating capacity increases, and the water temperature decreases; when the water temperature is lower than the set temperature, the speed of the compressor 50 decreases, the refrigerating capacity decreases, and the water temperature increases.

[0051] Specifically, the above-mentioned controller 70 and display screen 11 are both prior arts and do not belong to the technical content to be protected by this application, so no further details will be elaborated here.

[0052] Furthermore, the casing 10 further includes a cooling fan 80, and the air inlet of the cooling fan 80 faces the condenser and is used to guide the heat of the condenser out of the installation cavity. In this way, by setting the cooling fan 80 in the casing 10, when refrigerating, the heat of the condenser is guided out of the installation cavity through the cooling fan 80, and the gaseous refrigerant in the condenser dissipates heat into the environment under the action of the fan, improving the efficiency.

[0053] Furthermore, an air inlet 12 is provided on the side of the casing 10, and an air outlet 15 is provided at the end of the casing 10; the cooling fan 80 is installed in the installation cavity and is arranged opposite to the air outlet 15, and the condenser is installed in the installation cavity and is located on one side of the air inlet 12. In this way, when guiding and dissipating the heat of the condenser, the cooling fan 80 can be started, the external air flow can be introduced through the air inlet 12 on the side of the casing 10, then the air flow flows the heat on the surface of the condenser, and then the cooling fan 80 guides the heat to be exported through the air outlet 15.

[0054] Furthermore, the cooling fan 80, condenser, compressor 50, and water tank 20 are arranged in sequence in the installation cavity. In this way, by vertically placing the cooling fan 80, condenser, compressor 50, and water tank 20 and arranging them compactly in sequence inside the casing 10, the whole refrigeration host has a small volume and light weight.

[0055] Furthermore, a water injection port 13 can also be provided on the casing 10, and a water injection interface is correspondingly provided on the water tank, and the water injection port 13 is penetrated to the water injection interface of the water tank 20. In this way, water can be directly injected into the water tank 20 through the water injection port 13 on the casing 10 without taking out the water tank 20 for water injection, which is convenient for operation.

[0056] Furthermore, in order to facilitate the transfer of the cold compress device, a handle 14 is provided at the top of the casing 10, and a person can hold the handle 14 of the casing 10 to transfer the cold compress device.
