[0002] As people prioritize health, fitness has become a trend. However, post-exercise muscle soreness can severely impact daily life and work, and this issue is difficult to address effectively. Cold water baths are an effective way to accelerate muscle recovery and relieve fatigue. Currently, cold water baths require preparing a large amount of ice cubes in advance and placing them in a bucket filled with water to maintain the water temperature at a low enough temperature for muscle recovery.

[0003] The cold therapy effect of ice cubes places high demands on the insulation material of the ice bucket; otherwise, it is difficult to maintain the ideal water temperature and timeliness. The production, storage and transportation of ice cubes require additional equipment investment. Coupled with the limitation of one-time use of ice cubes, the overall cost of ice baths is high, which leads to the inconvenience of actual use of cold water baths. In addition, the ice bath process lacks massage function and has a relatively simple function.

[0004] Based on the above shortcomings, a cold water therapy bath machine is now proposed, which can quickly and stably provide a suitable ice bath water temperature during an ice bath and ensure the increased functionality of the cold water bath. Utility Model Content

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0034] Example 1:

[0035] like Figure 1—5 shows: a cold water therapy bath machine, comprising a barrel body 1, wherein the bottom of the barrel body 1 is isolated and provided with a water-proof working chamber 2, and a water treatment chamber 3 communicating with the barrel body 1 is provided above the water-proof working chamber 2, and a refrigeration component 4 and an oxygenation pump 8 are installed inside the water-proof working chamber 2, and the refrigerant pipeline of the heat exchanger 43 provided in the refrigeration component 4 is connected to the heat exchange tube 6, and the heat exchange tube 6 is inserted through the heat-conducting fin 5, and the heat-conducting fin 5 is installed in the slot opened on the water treatment chamber 3 and communicating with the barrel body 1. An electric heating pipe 7 is installed inside the water treatment chamber 3, the air outlet of the oxygen pump 8 is connected to one end of the air supply pipe 9, and the other end of the air supply pipe 9 is installed with an air stone 10, which is arranged inside the water treatment chamber 3. A controller 13 and a drain valve 14 are installed on the barrel body 1. The refrigeration component 4 can quickly and efficiently perform refrigeration, and the electric heating pipe 7 can heat the water body. In conjunction with the use of the heat-conducting fins 5 and the heat exchange tube 6, the water temperature in the barrel body 1 is quickly and stably maintained at a suitable ice bath temperature;When the oxygen pump 8 is working, the bubble stone 10 generates a large number of bubbles, which flow to the user's body surface after passing through the heat-conducting fins 5, thereby improving the comfort and cleanliness of the ice bath in the form of bubble massage. The refrigeration component 4 includes a condenser 41, the air outlet of the condenser 41 is connected to the air inlet of the heat exchanger 43 through a copper pipe, and an expansion valve 44 is installed on the copper pipe between the condenser 41 and the heat exchanger 43. A water pump 46 is installed between the heat exchange pipe 6 and the heat exchanger 43. The air inlet of the condenser 41 is connected to the compressor 4 through a copper pipe. 2, the air outlet of the heat exchanger 43 is connected to the air inlet of the compressor 42, and a cooling fan 45 is installed in front of the condenser 41. The refrigeration component 4 can quickly and stably perform refrigeration when working, and cooperate with the use of the water pump 46 to make the refrigerant in the heat exchange tube 6 cool down stably and quickly during the circulation process, and effectively reduce the water temperature after heat exchange with the water in the barrel 1. The heat exchange tube 6 is a serpentine copper tube structure, and the electric heating tube 7 is welded on the heat exchange tube 6. The heat exchange tube 6 arranged in a serpentine coil is arranged by the design of the electric heating tube 7. The heat exchange area with the water body is further increased, thereby quickly and efficiently exchanging heat and lowering the water temperature. The controller 13 includes a digital display switch, a relay and a single-chip microcomputer. A temperature sensor 12 is installed in the water treatment chamber 3. The refrigeration component 4, the electric heating pipe 7 and the temperature sensor 12 are electrically connected to the controller 13. The controller 13 can receive the water temperature signal fed back by the temperature sensor 12, and then control the operating state of the refrigeration component 4 and the electric heating pipe 7 to keep the water temperature at a suitable temperature. The drain valve 14 is installed on the barrel body 1 The bottom of the barrel 1 allows the operator to easily drain the water after opening the drain valve 14. The electric heating pipe 7 is installed at the bottom of the water treatment chamber 3 and is arranged between the bubble stone 10 and the heat-conducting fins 5. The water flows toward the heat-conducting fins 5 under the propulsion of the bubbles and is effectively heated as it passes through the electric heating pipe 7. The air supply pipe 9 is a U-shaped pipe structure. The top of the air supply pipe 9 is flush with the top of the barrel 1. The liquid level in the barrel 1 never exceeds the top of the air supply pipe 9, thereby preventing the water in the barrel 1 from flowing back into the aeration pump 8.

[0036] The working principle of this technical solution is as follows: after pouring an appropriate amount of water into the barrel 1, the refrigeration component 4 is started through the controller 13. After the refrigeration component 4 is powered on, the compressor 42 compresses the medium in the copper tube into a high-temperature and high-pressure gas, and then sends it to the condenser 41. The heat dissipation fan 45 works to dissipate heat from the condenser 41, so that the medium in the tube becomes a medium-temperature and high-pressure liquid. The medium then passes through the expansion valve 44 to throttle and reduce the pressure and becomes a low-temperature and low-pressure gas-liquid mixture. When entering the heat exchanger 43, it absorbs the heat of the coolant in the heat exchange tube 6 and vaporizes, becoming a low-temperature gas, and then returns to the condenser 41 to continue compression. Continue to circulate and refrigerate; the coolant in the heat exchange tube 6 exchanges heat with the water in the barrel 1 through the heat-conducting fins 5 under the circulation of the water pump 46, thereby quickly reducing the temperature of the water to a suitable ice bath temperature; when the water needs to be heated, the refrigeration component 4 is powered off and the electric heating tube 7 is powered on to heat the water; when massage is needed, the oxygen pump 8 can be controlled to run, so that the oxygen pump 8 quickly sends air into the air supply pipe 9, and then a large number of bubbles are formed through the bubble stone 10. After passing through the heat-conducting fins 5, the bubbles rush to the user's body surface, thereby improving the comfort and cleanliness of the ice bath in the form of bubble massage.
