Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and belongs to a liquid circulating refrigeration device used in beauty instruments. Background Technology

[0002] Liquid circulating refrigeration equipment is a device that provides a stable low-temperature environment for beauty instruments. This is one of the most common refrigeration methods. The refrigeration equipment mainly consists of a compressor, condenser, expansion valve, and evaporator. The compressor compresses the refrigerant into a high-temperature, high-pressure gas, which then dissipates heat through the condenser and becomes a high-temperature, high-pressure liquid. After being depressurized by the expansion valve, the refrigerant becomes a low-temperature, low-pressure liquid and enters the evaporator to absorb heat, achieving the cooling effect. The circulation pump in the circulation system is responsible for circulating the cooled liquid within the device, exchanging heat with the beauty instrument to remove the heat generated by the instrument, thereby achieving the cooling purpose.

[0003] For example, the circulating drinking liquid refrigeration heat exchanger and refrigeration equipment disclosed in the prior art (CN209639306U) can effectively improve the heat exchange efficiency of the semiconductor refrigeration system, significantly improve the refrigeration efficiency, and provide rapid refrigeration.

[0004] However, the existing technologies described above still have the following problems in use: traditional refrigerators can usually only cool liquids to room temperature, which cannot meet the needs of precision instruments for low-temperature liquids. Furthermore, most refrigeration devices require external compressors or complex heat dissipation systems, making them difficult to integrate into the instrument. They also lack a mechanism for linking flow rate and cooling power, resulting in insufficient cooling speed and stability. Based on this, this invention provides a compact, highly efficient, and temperature-adjustable liquid circulation refrigeration device for beauty instruments. Utility Model Content

[0005] Therefore, this utility model provides a liquid circulating refrigeration device for beauty instruments to solve the problems of low refrigeration efficiency, large size and inflexible temperature control of traditional refrigerators in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A liquid circulation cooling device for a beauty instrument includes a metal cooling module, two TEC cooling modules, and two heat sinks. The cooling ends of the two TEC cooling modules are in contact with the outer wall of the metal cooling module, and the heating ends of the two TEC cooling modules are in contact with the two heat sinks. Both heat sinks are detachably fixed to the metal cooling module. The metal cooling module has a circulation pipe inside. The front end of the metal cooling module is fixedly provided with an inlet and an outlet connected to the circulation pipe. The outlet is connected to the liquid circuit of the beauty instrument. The device also includes a shell for enclosing the metal cooling module, the TEC cooling modules, and the heat sinks.

[0008] Furthermore, the metal refrigeration module is made of metal, and the circulation pipe is spiral or in a straight line.

[0009] Furthermore, a metal heat-conducting plate is fixedly installed on the side of the two heat sinks that are close to each other. The side of the two metal heat-conducting plates that are close to each other is machined with a groove that is compatible with the TEC cooling module. The installation of the metal heat-conducting plate can improve the stability of the TEC cooling module between the metal cooling module and the heat sink, and at the same time improve the thermal conductivity.

[0010] Furthermore, a flow regulating valve is connected to the water inlet, one end of which is connected to a circulation pump. A connector is connected to the circulation pump and is connected to the liquid circuit of the beauty instrument. The flow regulating valve can automatically adjust the liquid flow rate.

[0011] Furthermore, two vertically distributed limiting plates are fixedly provided on the inner walls of both sides of the outer shell. Multiple limiting plates are located between the metal refrigeration module and the two heat sinks. A storage groove is opened on one side of the outer shell. The connector penetrates the outer shell and extends into the storage groove. With the cooperation of multiple limiting plates, it is convenient for operators to quickly install the metal refrigeration module, TEC refrigeration module and heat sinks, and store the connector in the storage groove to prevent the connector from protruding outward and reduce the space occupied by the entire device.

[0012] Furthermore, baffles can be detachably connected to both the front and rear sides of the outer casing. An air inlet is provided on the baffle at the rear of the outer casing, and an air outlet is provided on the baffle at the front of the outer casing.

[0013] Furthermore, both the air inlet and the air outlet are fixedly equipped with mounting brackets, and multiple evenly distributed cooling fans can be detachably installed on both mounting brackets. Filter screens are embedded on the side of the two mounting brackets that are far apart from each other. The filter screens can filter dust and debris from the external environment and prevent dust and debris from affecting the heat dissipation effect.

[0014] Furthermore, a rectangular groove is provided on the top of the housing, and a controller and a temperature sensor are installed inside the rectangular groove. The temperature sensor is connected to the input terminal of the controller, and the flow regulating valve, the circulating pump and the cooling fan are all connected to the output terminal of the controller.

[0015] This utility model has the following advantages:

[0016] 1. This utility model integrates a metal cooling module, a TEC cooling module, a radiator, and a circulating pump into a small housing, making it suitable for internal installation in beauty and medical instruments. By detecting the liquid temperature, it facilitates intelligent control of the TEC cooling module's power, ensuring rapid cooling. At the same time, the use of two radiators achieves efficient heat dissipation, preventing heat backflow from affecting the cooling effect.

[0017] 2. Several cooling fans are installed inside the baffles on the front and rear sides of the outer casing. The cooling fans accelerate the ventilation speed inside the casing, which can improve the heat dissipation effect to a certain extent. At the same time, the filter screen can block dust and debris, thus improving the heat dissipation effect. Attached Figure Description

[0027] Refer to the instruction manual appendix Figures 1-5 This utility model provides a liquid circulation cooling device for beauty instruments, including a metal cooling module 1, two TEC cooling modules 2, two heat sinks 3, and a shell 7 enclosing the above parts. The cooling ends of the two TEC cooling modules 2 are in contact with the outer wall of the metal cooling module 1, and the heating ends of the two TEC cooling modules 2 are in contact with the two heat sinks 3. Both heat sinks 3 are detachably fixed to the metal cooling module 1. The metal cooling module 1 is provided with a circulation pipe 4 inside, and the metal cooling module 1 is made of metal (such as copper or aluminum alloy) to improve the heat conduction rate. The circulation pipe 4 is spiral or in a straight line. The front end of the metal cooling module 1 is fixed with an inlet 5 and an outlet 6 connected to the circulation pipe 4. The outlet 6 is connected to the liquid circuit of the beauty instrument.

[0028] Metal heat-conducting plates 8 are fixedly installed on the side of each of the two heat sinks 3 that are close to each other. The side of each of the two metal heat-conducting plates 8 that is close to each other is machined with grooves 9 that are compatible with the TEC cooling module 2. In actual use, an insulating coating is applied to the surface of the metal heat-conducting plates 8 to provide insulation. At the same time, the installation of metal heat-conducting plates 8 can improve the stability of the TEC cooling module 2 between the metal cooling module 1 and the heat sink 3. In addition, the installation of metal heat-conducting plates 8 can also improve the thermal conductivity.

[0029] A flow regulating valve 10 is connected to the water inlet 5. One end of the flow regulating valve 10 is connected to a circulation pump 11. A connector 12 is connected to the circulation pump 11. The connector 12 is connected to the liquid circuit of the beauty instrument. The flow regulating valve 10 can automatically adjust the liquid flow rate.

[0030] Two vertically distributed limiting plates 13 are fixedly installed on the inner walls of both sides of the outer casing 7. Multiple limiting plates 13 are located between the metal refrigeration module 1 and the two heat sinks 3. A storage groove 14 is opened on one side of the outer casing 7. The connector 12 passes through the outer casing 7 and extends into the storage groove 14. With the cooperation of multiple limiting plates 13, it is convenient for operators to quickly install the metal refrigeration module 1, the TEC refrigeration module 2 and the heat sink 3, and store the connector 12 in the storage groove 14 to prevent the connector 12 from protruding outward and reduce the space occupied by the entire device.

[0031] A rectangular recess 21 is provided on the top of the outer casing 7. A controller 22 and a temperature sensor 23 are installed inside the rectangular recess 21. The probe of the temperature sensor 23 is inserted into the water inlet 5 to monitor the liquid temperature in real time (e.g., ...). Figure 3 As shown, temperature sensor 23 is connected to the input terminal of controller 22, and flow regulating valve 10, circulating pump 11 and cooling fan 19 are all connected to the output terminal of controller 22, thus setting controller 22 to achieve intelligent control.

[0032] In actual use, the liquid circuit of the beauty instrument is first connected to connector 12 and outlet 6. Circulation pump 11 draws in liquid, which enters the circulation pipeline in the metal cooling module 1 through connector 12, flow regulating valve 10 and inlet 5 for cooling. Then it flows out from outlet 6 and is transported back to the liquid circuit, thus achieving circulating cooling. At the same time, temperature sensor 23 on the outer shell 7 monitors the liquid temperature in real time and feeds it back to controller 22. After analyzing and processing the temperature data, controller 22 adjusts the power of TEC cooling module 2 and the speed of circulation pump 11 to achieve precise control of the liquid cooling effect. It can achieve an ultra-low temperature cooling effect of 5-10℃. The heat from the heating end of TEC cooling module 2 is efficiently conducted to radiator 3 through metal heat conduction plate 8, and then quickly dissipated by radiator 3, avoiding overheating of TEC cooling module 2 and affecting the control of cooling effect. The whole device is small in size and suitable for integration into beauty instruments.

[0033] Refer to the instruction manual appendix Figures 1-5 Both the front and rear sides of the outer casing 7 are detachably connected to baffles 15. An air inlet 16 is provided on the baffle 15 at the rear of the outer casing 7, and an air outlet 17 is provided on the baffle 15 at the front of the outer casing 7. Mounting brackets 18 are fixedly installed inside the air inlet 16 and the air outlet 17. Multiple evenly distributed cooling fans 19 are detachably installed on both mounting brackets 18. Filters 20 are embedded on the side of the two mounting brackets 18 that is far apart from each other.

[0034] The controller 22 controls multiple cooling fans 19 in the air inlet 16 to blow air into the outer casing 7, and multiple cooling fans 19 in the air outlet 17 to draw heat from the outer casing 7, thereby increasing the speed at which heat is expelled from the outer casing 7 and thus improving the heat dissipation effect to a certain extent.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
