Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a portable cold therapy system and device with optional heating and compression therapies. Background Art

[0002] Cold therapy systems and devices are widely used in the fields of sports rehabilitation, pain relief, swelling elimination, wound healing, etc.

[0003] The existing cold therapy systems and devices mainly use semiconductor refrigeration, and the cold therapy systems and devices using semiconductor refrigeration have the following disadvantages:

[0004] 1. When using semiconductor refrigeration, the temperature control of the cold therapy device is limited. If it is not properly controlled, it may cause excessive heat loss of the chip and even lose the cooling effect.

[0005] 2. The refrigeration effect of semiconductor refrigeration is easily affected by the ambient temperature. When the ambient temperature exceeds a specific range, it is difficult to effectively absorb heat, resulting in a decrease in the cooling effect.

[0006] 3. Generally, semiconductor refrigeration fixes the refrigeration chip on the heat sink and controls the operation of the chip through current to take away heat. When current passes through the chip, the N-type semiconductor absorbs the surrounding heat, while the P-type semiconductor releases heat. This makes one side of the chip in a low-temperature state and the other side in a high-temperature state. By connecting a water pipe and flowing water through the low-temperature surface of the chip, the use of electric energy to drive refrigeration is realized. This method has high power consumption, a large device volume, and requires mains power supply. It is difficult to use in an environment without mains power or far from mains power and is not convenient for outdoor use and portability.

Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the efficacy that this application can produce and the purpose that can be achieved, should still fall within the scope covered by the technical content disclosed in this application.

[0091] In a first aspect, referring to Figures 1 - 10 , Figure 12 , Figure 13 , Figures 16 - 19 , Figure 28 , Figure 29 As shown in

[0092] Among them, the liquid storage tank 12 includes a first liquid inlet 121 and a first liquid outlet 122. The liquid in the liquid storage tank 12 can flow into the first protective gear A through the first liquid outlet 122, and the liquid in the first protective gear A can flow into the liquid storage tank 12 through the first liquid inlet 121; the heat exchanger 15 includes a first cooling plate 151 disposed inside the liquid storage tank 12; a first air outlet 1511, a first air inlet 1512, a second liquid inlet 1513, and a second liquid outlet 1514 are provided on the first cooling plate 151; the first air outlet 1511 is connected to the first pipeline 171, and the first air inlet 1512 is connected to the second pipeline 172; the second liquid inlet 1513 is connected to the first liquid inlet 121 through a fourth pipeline 177.

[0093] It should be noted that the compressor 11, the condenser 13, the fan 14, and the heat exchanger 15 can each be one or more. A plurality of the compressors 11 are connected in series; a plurality of the condensers 13 are connected in series, and the working surface of each fan 14 faces each condenser 13; a plurality of the heat exchangers 15 are connected in series.

[0094] It should be noted that the liquid is water, alcohol, antifreeze, etc.; preferably, alcohol with a concentration of 10% is used.

[0095] It should be noted that the first liquid inlet 121 can be provided at the top of the liquid storage tank 12, as shown in Figure 2 、 Figure 6 ; the first liquid inlet 121 can also be provided on the side of the liquid storage tank 12, as shown in Figure 3 、 Figure 12 .

[0096] It should be noted that the first pipeline 171 is branched with a refrigerant addition port to maintain the refrigeration temperature under the long-term operation of the refrigeration mechanism; when the refrigeration mechanism is used in long-term circulation, it is not possible to completely achieve the heat exchange in the ideal state, and the refrigeration effect cannot reach the expected value. The refrigerant can be added regularly to improve the refrigeration effect.

[0097] It should be noted that the first cooling plate 151 is a brazed plate heat exchanger. The liquid in the first protective gear A flows into the second liquid inlet 1513 through the first liquid inlet 121. After the liquid is cooled in the brazed plate heat exchanger, it then flows into the liquid storage tank 12 through the second liquid outlet 1514.

[0098] It should be noted that the first pipe 171 is in fluid communication with the second pipe 172, and the second pipe 172 is in fluid communication with the third pipe 173. In fact, the first pipe 171, the second pipe 172, and the third pipe 173 are all on the same pipe, and the same pipe connects the compressor 11, the heat exchanger 15, and the condenser 13 to form a closed circulation loop. Exemplarily, the first pipe 171 includes a compressor section, a first pipe connection section extending from the compressor 11 to connect to the heat exchanger 15, and a heat exchanger section; the second pipe 172 includes a second pipe connection section extending from the heat exchanger 15 to connect to the condenser 13, and a condenser section; the third pipe 173 includes a third pipe connection section extending from the condenser 13 to connect to the compressor 11.

[0099] It should be noted that the refrigerant enters the first cooling plate 151 through the second pipe 172 and the first air inlet 1512, and then returns to the compressor 11 through the first air outlet 1511 and the first pipe 171, so as to cool down the first cooling plate 151 and exchange heat with the liquid in the first cooling plate 151, thereby reducing the liquid temperature.

[0100] The problem to be solved in this embodiment is the technical problem of insufficient cooling effect and low efficiency of the protective gear refrigeration mechanism.

[0101] According to a portable cryotherapy system with an optional heating and compression therapy provided by the present utility model, the beneficial effects are as follows: The refrigeration mechanism is provided with a compressor 11, a condenser 13, a fan 14, and a heat exchanger 15. The high-temperature and high-pressure gaseous refrigerant is transported from the compressor 11 to the condenser 13 through the third pipe 173 for heat dissipation, and then the refrigerant liquefies. At this time, the high-temperature and high-pressure gaseous refrigerant has a relatively high temperature. The fan 14 is used to dissipate heat from the gaseous refrigerant in the condenser 13, and the gaseous refrigerant releases heat and liquefies; the liquid refrigerant is transported from the condenser 13 to the heat exchanger 15 through the second pipe 172, and the liquid refrigerant exchanges heat with the liquid in the liquid storage tank 12 in the heat exchanger 15, absorbs the heat of the liquid and then vaporizes, and the liquid temperature drops; the gaseous refrigerant is transported from the heat exchanger 15 to the compressor 11 through the first pipe 171, and the compressor 11 is used to compress the gaseous refrigerant; the liquid in the liquid storage tank 12 is cooled cyclically. The liquid with a reduced temperature in the liquid storage tank 12 flows into the first protective gear A through the first liquid outlet 122, and the liquid in the first protective gear A flows into the liquid storage tank 12 through the first liquid inlet 121, and the liquid is recycled and cooled cyclically. The first protective gear A is used to perform cold compress on the body to achieve a physiotherapy effect; Refer to Figure 28 As shown, the refrigeration speed: Under the condition that the ambient temperature is 25 - 28 °C, with the first protective gear A with an area of 1 m 2 The surface temperature of the first protective gear A reaches 5 °C within 10 minutes, the refrigeration electric power is 75 watts, the achieved refrigeration capacity is 250 watts, and the refrigeration effect is good, the efficiency is high, it is stable, and the power is low. In addition, the device has a compact structure, is small and light, and is convenient to carry.

[0102] In addition, since the refrigeration and heating mechanisms of the present application are arranged inside or at the outer bottom of the liquid storage tank 12, they can be in direct or indirect contact with the liquid in the liquid storage tank 12, and can pre-cool or pre-heat the liquid, so that it can be immediately used when the user needs treatment.

[0103] In one embodiment, a liquid level detector 61 and a temperature sensor 62 are further arranged in the liquid storage tank 12, and both the liquid level detector 61 and the temperature sensor 62 are electrically connected to the control assembly.

[0104] It should be noted that the liquid level detector 61 is arranged in the liquid storage tank 12 to detect the height of the liquid level; the temperature sensor 62 is arranged on the side of the liquid storage tank 12 to detect the temperature of the liquid in the liquid storage tank 12, so as to control the temperature through the control assembly to achieve a suitable cold compress or hot compress effect.

[0105] In one embodiment, the second pipeline 172 includes a throttling device, and the throttling device is arranged between the heat exchanger 15 and the condenser 13; the condenser 13 includes a heat conducting pipe, one end of the heat conducting pipe extends out of the condenser 13 and is connected to the throttling device, and the other end of the heat conducting pipe extends out of the condenser 13 and is connected to the compressor 11.

[0106] It should be noted that the second pipeline 172 includes a second pipeline connection section extending out of the heat exchanger 15 to connect to the condenser 13 and a condenser section, and the throttling device is arranged on the second pipeline connection section extending out of the heat exchanger 15 to connect to the condenser 13; the throttling device can be a capillary pipeline, and the second pipeline connection section has a tendency to reduce the pipeline diameter after extending out of the heat exchanger 15 to form a capillary pipeline. Preferably, the diameter is reduced to 3-6 times the original pipeline diameter; the throttling device can also be a throttle valve, or other throttling and pressure reducing devices.

[0107] It is worth noting that the liquid refrigerant after heat dissipation passes through the capillary pipeline with a smaller diameter. Due to the smaller cross-sectional area of the pipeline, the flow velocity becomes slower, thereby reducing its pressure, and at the same time, the temperature also decreases; at this time, the liquid refrigerant with a higher pressure just output from the condenser 13 can be depressurized through the capillary pipeline.

[0108] It should be noted that the heat conducting pipe is a copper pipe, and the copper pipe is in a "U" shape and is arranged along the inner wall of the condenser 13 in a curved manner. The high-temperature and high-pressure gaseous refrigerant enters the condenser section, and the pipeline of the condenser section is provided with a copper pipe, which absorbs the heat of the gaseous refrigerant and gradually dissipates it into the surrounding environment; at the same time, the working surface of the fan 14 faces the position of the copper pipe in the condenser 13, further enabling the refrigerant to dissipate heat and liquefy. The liquid refrigerant after heat dissipation through the copper pipe and the fan 14 enters the capillary pipeline for pressure reduction, and the liquid refrigerant is transported to the heat exchanger 15 through the second pipeline 172.

[0109] In one embodiment, a water pump 21 is further included. The first liquid outlet 122 is connected to the third liquid inlet A1 of the first protector A through the water pump 21, and the water pump 21 is electrically connected to the control component;

[0110] When the water pump 21 works, the liquid in the liquid storage tank 12 flows into the first protector A through the first liquid outlet 122 and the third liquid inlet A1, and the liquid in the first protector A flows back to the liquid storage tank 12 through the third liquid outlet A2 of the first protector A and the first liquid inlet 121.

[0111] It should be noted that, as shown in Figure 7 shown, the first liquid inlet 121 is connected to a first adapter, and the first liquid outlet 122 is connected to a second adapter 123; the first adapter and the second adapter 123 are respectively used for connecting to a liquid pipeline. The liquid in the liquid storage tank 12 flows out from the first liquid outlet 122 and then flows into the first protector A after being pressurized by the water pump 21.

[0112] In one embodiment, as shown in Figure 10 shown, a four-way valve 18 is further included; the compressor 11 is connected to the four-way valve 18 through the first pipeline 171 and then connected to the heat exchanger 15; the condenser 13 is connected to the four-way valve 18 through the third pipeline 173 and then connected to the compressor 11; the four-way valve 18 is electrically connected to the control component, and the control component controls the four-way valve 18 to change the fluid flow direction so that the gaseous refrigerant in the compressor 11 first passes through the heat exchanger 15 and then passes through the condenser 13 to achieve a heating effect.

[0113] It should be noted that the control component controls the internal passage of the four-way valve 18, so that the high-temperature and high-pressure gaseous refrigerant in the compressor 11 first passes through the heat exchanger 15. The high-temperature and high-pressure gaseous refrigerant dissipates heat and liquefies in the heat exchanger 15, so that the temperature of the liquid in the liquid storage tank 12 rises. The liquid refrigerant passes through the capillary pipeline to reduce the pressure and then passes through the condenser 13 to absorb heat and gasify. The gaseous refrigerant then returns to the compressor 11. By setting the four-way valve 18, only one heat exchanger 15 needs to be set to realize refrigeration or heating of the liquid, reducing the component setting (such as the heating tube 16) and saving costs.

[0114] In one embodiment, as shown in Figure 12 、 Figure 13 shown, a heating mechanism is further included. The heating mechanism includes a heating tube 16; the heating tube 16 is arranged inside the liquid storage tank 12 and is electrically connected to the control component.

[0115] It should be noted that when it is necessary to heat the liquid in the liquid storage tank 12, the compressor 11, the condenser 13, and the fan 14 are controlled by the control component to suspend operation, and the heating tube 16 is made to work by the control component, so as to increase the temperature of the liquid in the liquid storage tank 12. The liquid with increased temperature flows into the first protective device A through the third liquid inlet A1, so that the first protective device A has a hot compress function. The heating mechanism is controlled by the control component to increase the temperature of the liquid in the liquid storage tank 12. Refer to Figure 29 As shown, heating speed: under the condition that the ambient temperature is 25 - 28 °C, when paired with the first protective device A with an area of 1 m 2 , the surface temperature of the first protective device A reaches 43 °C within 8 minutes, the heating electric power is 150 watts, and the heating quantity reached is 150 watts, with good heating effect, high efficiency, and stability.

[0116] In one embodiment, it further includes a first air pump 22, a first solenoid valve 23, and a first air pipe 174. The first air pump 22 is connected to the first protective device A through the first air pipe 174, and the first solenoid valve 23 is arranged on the first air pipe 174; both the first air pump 22 and the first solenoid valve 23 are electrically connected to the control component; the first protective device A is inflated through the first air pump 22, and the first protective device A deflates through the first solenoid valve 23.

[0118] In one embodiment, a pressure relief valve 27 and a pressure sensor 63 are further arranged on the first air pipe 174, and the pressure sensor 63 is electrically connected to the control component.

[0119] It should be noted that when the pressure sensor 63 detects that the pressure in the first air pipe 174 is too high, the first air pump 22 can be controlled to close and the first solenoid valve 23 can be opened to deflate the first protective device A; when the first air pump 22 or the first solenoid valve 23 fails, the pressure relief valve 27 can be used to deflate.

Refer to Figure 15 As shown, the heat exchanger 15 includes a second cooling plate 153; a second air outlet 1531 and a second air inlet 1532 are provided on the second cooling plate 153. The second air outlet 1531 is connected to the first pipeline 171, and the second air inlet 1532 is connected to the second pipeline 172; the liquid storage tank 12 is made of a heat-conducting material.

[0138] It should be noted that the liquid storage tank 12 and the second cooling plate 153 are made of copper. The liquid refrigerant enters the second cooling plate 153 at the outer bottom of the liquid storage tank 12 through the second pipeline 172 and the second air inlet 1532 and then exits through the second air outlet 1531 and the first pipeline 171, so as to cool down the second cooling plate 153, cool down the whole liquid storage tank 12 through the second cooling plate 153, and further reduce the temperature of the liquid in the liquid storage tank 12. The second cooling plate 153 and the liquid storage tank 12 can be integrally formed or separately provided.

[0139] In one embodiment, the heat exchanger 15 may include one or a combination of the first cooling plate 151, the spiral tube 152, and the second cooling plate 153.

[0140] It should be noted that after the liquid refrigerant enters the first cooling plate 151, the spiral tube 152 or the second cooling plate 153 through the second pipe 172, the first cooling plate 151, the spiral tube 152 or the second cooling plate 153 is cooled, and then the temperature of the liquid in the liquid storage tank 12 drops.

[0141] The problem to be solved in this embodiment lies in the technical problems of insufficient cooling effect and low efficiency of the refrigeration mechanism.

[0142] According to a portable cryotherapy system with an optional heating and compression therapy provided by the present utility model, the beneficial effects are as follows: The refrigeration mechanism is provided with a compressor 11, a condenser 13, a fan 14 and a heat exchanger 15.

The fan 14 is used to dissipate heat from the gaseous refrigerant in the condenser 13, and the gaseous refrigerant releases heat and liquefies. The liquid refrigerant is transported from the condenser 13 to the heat exchanger 15 through the second pipe 172. The liquid refrigerant exchanges heat with the liquid in the liquid storage tank 12 in the heat exchanger 15, vaporizes after absorbing the heat of the liquid, and the temperature of the liquid drops. The gaseous refrigerant is transported from the heat exchanger 15 to the compressor 11 through the first pipe 171, and the compressor 11 is used to compress the gaseous refrigerant. The liquid in the liquid storage tank 12 is cooled cyclically. The liquid with a decreased temperature in the liquid storage tank 12 flows into the first protective device A through the first liquid outlet 122, and the liquid in the first protective device A flows into the liquid storage tank 12 through the first liquid inlet 121. The liquid is recycled and cooled cyclically, and the first protective device A is used to perform cold compress on the body to achieve a physical therapy effect; Refer to Figure 28 As shown, refrigeration speed: Under the condition that the ambient temperature is 25 - 28 °C, with the first protective device A having an area of 1 m 2 ², the surface temperature of the first protective device A reaches 5 °C within 10 minutes, the refrigeration electric power is 75 watts, and the achieved refrigeration capacity is 250 watts. The refrigeration effect is good, the efficiency is high, it is stable, and the power is low. Secondly, an air pump and an electromagnetic valve are provided. The protective device can be inflated to expand and thus fit the treatment site more closely, so as to improve the treatment effect of the cryotherapy liquid / heat therapy liquid, and the protective device can achieve medical effects such as massage through the combination of inflation / deflation; and the device can be simultaneously connected to the first protective device A, the second protective device B, and the third protective device C to be used by three users at the same time, with a high utilization rate of the device. In addition, the system has a compact structure, is small and light, and is convenient to carry.

[0143] In addition, because the refrigeration and heating mechanisms of the present application are arranged inside or at the outer bottom of the liquid storage tank 12, they can be in direct or indirect contact with the liquid in the liquid storage tank 12, and can pre-cool or pre-heat the liquid, so that it can be immediately used when the user needs treatment.

[0144] In one embodiment, it further includes a housing, a bracket 31 and a connector 41. The housing includes a bottom case 32, an upper case 33 and a face cover 34. The bracket 31 is embedded in the housing, and the liquid storage tank 12 is arranged on the bracket 31. An avoidance portion is provided on the bracket 31, and the condenser 13 is embedded in the avoidance portion. A first groove 321 is provided on the outer side of the side of the bottom case 32. One end of the connector 41 is inserted into the first groove 321 and then connected to the first liquid outlet 122, the first liquid inlet 121 and the first air pipe 174 respectively. The other end of the connector 41 is used to connect to a plurality of pipes, so that the first liquid outlet 122, the first liquid inlet 121 and the first air pipe 174 are respectively connected to the first protective device A. A first air hole 71 and a second air hole 72 are further provided on the bottom case 32, and the first air hole 71 and the second air hole 72 are located below the first groove 321. One side of the first air hole 71 is connected to the second air pipe 175, and one side of the second air hole 72 is connected to the third air pipe 176. The other sides of the first air hole 71 and the second air hole 72 are used to connect to pipes, so that the second air pipe 175 and the third air pipe 176 are respectively connected to the second protective device B and the third protective device C.

[0145] In one embodiment, the control assembly includes a main control board 51, a display screen 52 and a battery 53. The display screen 52 and the battery 53 are both electrically connected to the main control board 51. The display screen 52 is arranged on the face cover 34. A second groove 322 is formed by the depression of one side of the outer bottom of the bottom case 32 towards one side of the bracket 31, and the battery 53 is arranged in the second groove 322. The battery is a storage battery.

[0146] It should be noted that by controlling the main control board 51 through the display screen 52, the working temperature of the first protective device A can be set, and the air pressure values of the first protective device A, the second protective device B and the third protective device C can be set. The pressing effect can be achieved by adjusting the inflation / deflation method.

[0149] It should be noted that the control component controls the passage inside the four-way valve 18, so that the high-temperature and high-pressure gaseous refrigerant in the compressor 11 first passes through the heat exchanger 15. The high-temperature and high-pressure gaseous refrigerant dissipates heat and liquefies in the heat exchanger 15, increasing the temperature of the liquid in the liquid storage tank 12. The liquid refrigerant passes through the capillary pipeline to reduce the pressure and then absorbs heat and vaporizes through the condenser 13, and the gaseous refrigerant returns to the compressor 11 again. By setting the four-way valve 18, only one heat exchanger 15 is needed to realize the refrigeration or heating of the liquid, reducing the component setting (such as the heating tube 16) and saving costs.

[0150] In the third aspect, referring to Figures 20 - 25 、 Figure 30 、 Figure 31 As shown in, the present invention provides a portable cryotherapy system with optional heating and compression therapy, which is applied to the first protective device A and includes a refrigeration mechanism, a liquid storage tank 12, and a control component; the refrigeration mechanism includes: a compressor 11, a condenser 13, a fan 14, and a heat exchanger 15; the control component is electrically connected to the compressor 11, the condenser 13, and the fan 14 respectively; the compressor 11, the heat exchanger 15, the condenser 13, and the fan 14 are all arranged outside the liquid storage tank 12; the intake port of the compressor 11 is connected to the heat exchanger 15 through the first pipeline 171; the heat exchanger 15 is connected to the condenser 13 through the second pipeline 172; the condenser 13 is connected to the outlet of the compressor 11 through the third pipeline 173; the first pipeline 171 and the second pipeline 172 are in fluid communication, and the second pipeline 172 and the third pipeline 173 are in fluid communication, so that the gaseous refrigerant in the compressor 11 first passes through the condenser 13 and then passes through the heat exchanger 15, achieving a refrigeration effect; the working surface of the fan 14 faces the condenser 13;

[0151] The liquid storage tank 12 includes a first liquid outlet 122. The liquid in the liquid storage tank 12 can flow through the first liquid outlet 122, pass through the heat exchanger 15, and then flow into the first protective gear A. The liquid in the first protective gear A can flow through the heat exchanger 15 and then flow back into the first protective gear A, or flow into the liquid storage tank 12 through the first liquid outlet 122. It further includes a heating mechanism, and the heating mechanism is electrically connected to the control component.

[0152] It should be noted that the compressor 11, the condenser 13, the fan 14, and the heat exchanger 15 can each be one or more. A plurality of the compressors 11 are arranged in series; a plurality of the condensers 13 are arranged in series, and the working surface of each fan 14 faces each condenser 13; a plurality of the heat exchangers 15 are arranged in series.

[0154] In one embodiment, refer to Figure 21 As shown, the heating mechanism includes a heating sheet 161; the heating sheet 161 is arranged outside the heat exchanger 15; the heating sheet 161 is one or more.

[0155] It should be noted that the liquid is water, alcohol, antifreeze, etc.; preferably, alcohol with a concentration of 10% is used.

[0156] It should be noted that the first pipeline 171 is branched with a refrigerant addition port to maintain the refrigeration temperature during the long-term operation of the refrigeration mechanism; when the refrigeration mechanism is used in long-term circulation, it is not possible to completely achieve the heat exchange under the ideal state, and the refrigeration effect cannot reach the expectation. Refrigerant can be added regularly to improve the refrigeration effect.

[0157] It should be noted that the first pipe 171 is in fluid communication with the second pipe 172, and the second pipe 172 is in fluid communication with the third pipe 173. In fact, the first pipe 171, the second pipe 172, and the third pipe 173 are all on the same pipe, and the same pipe connects the compressor 11, the heat exchanger 15, and the condenser 13 to form a closed circulation loop.

The high-temperature and high-pressure gaseous refrigerant is transported from the compressor 11 to the condenser 13 through the third pipe 173. At this time, the high-temperature and high-pressure gaseous refrigerant has a relatively high temperature. The fan 14 is used to dissipate heat from the gaseous refrigerant in the condenser 13, and the gaseous refrigerant releases heat and liquefies; the liquid refrigerant is transported from the condenser 13 to the heat exchanger 15 through the second pipe 172. The liquid refrigerant exchanges heat with the liquid in the heat exchanger 15, vaporizes after absorbing the heat of the liquid, and the temperature of the liquid drops; the gaseous refrigerant is transported from the heat exchanger 15 to the compressor 11 through the first pipe 171, and the compressor 11 is used to compress the gaseous refrigerant; the heat exchanger 15 is arranged outside the liquid storage tank 12. The liquid in the liquid storage tank 12 first flows into the heat exchanger 15 through the first liquid outlet 122 for cooling and then flows into the first protective device A. The liquid in the first protective device A can flow into the heat exchanger 15 again for cooling, or the liquid in the first protective device A can flow back into the liquid storage tank 12, so that the first protective device A has a cold compress function, and the remaining liquid in the liquid storage tank 12 will no longer participate in the cycle, greatly improving the refrigeration efficiency and reducing the power consumption; refer to Figure 30 As shown, the refrigeration speed: under the condition that the ambient temperature is 25-28 °C, with the first protective device with an area of 1 m 2 The surface temperature of the first protective device reaches 5 °C within 5 minutes, the refrigeration electric power is 75 watts, and the refrigeration capacity reached is 250 watts. The refrigeration effect is good, the efficiency is high, it is stable, and the power is low. On the second hand, a heating mechanism is also provided. The heating mechanism includes a four-way valve 18 or a heating element 161. By controlling the control component to control the four-way valve 18 to change the fluid flow direction or control the heating element 161 to generate heat, the temperature of the liquid in the heat exchanger is increased, and the liquid with an increased temperature flows into the first protective device through the third liquid inlet, so that the first protective device has a hot compress function, refer to Figure 31As shown, heating rate: under the condition that the ambient temperature is 25 - 28 °C, with the first protective gear having an area of 1 m 2 The surface temperature of the first protective gear reaches 43 °C within 6 minutes, the heating electric power is 75 - 150 watts, and the achieved heating quantity is 75 - 150 watts. It has good heating effect, high efficiency and stability. In addition, the system has a compact structure, is small and light, and is convenient to carry.

[0160] In one embodiment, it further includes a heat preservation device, and the heat preservation device is arranged outside the heating sheet 161. The heat preservation device can be a mica sheet.

[0161] In one embodiment, referring to Figures 23 - 25 As shown, the heat exchanger includes a third cooling plate 154; the third cooling plate 154 is provided with a third air inlet 1541, a third air outlet 1542, a fourth liquid inlet 1543 and a fourth liquid outlet 1544; the third air outlet 1542 is connected to the first pipe 171, and the third air inlet 1541 is connected to the second pipe 172; the fourth liquid inlet 1543 is connected to the first liquid outlet 122, the fourth liquid outlet 1544 is connected to the third liquid inlet A1 of the first protective gear A, and the third liquid outlet A2 of the first protective gear A is connected to the first liquid outlet 122 and the fourth liquid inlet 1543.

[0162] It should be noted that the third cooling plate 154 is a brazed plate heat exchanger. The liquid in the liquid storage tank 12 flows into the fourth liquid inlet 1543 through the first liquid inlet 121. After the liquid is cooled in the brazed plate heat exchanger, it then flows into the first protective gear A through the fourth liquid outlet 1544.

[0163] It is worth noting that the refrigerant enters the third cooling plate 154 through the second pipe 172 and the third air inlet 1541, and then returns to the compressor 11 through the third air outlet 1542 and the first pipe 171, so as to cool down the third cooling plate 154 and exchange heat with the liquid in the third cooling plate 154, thereby making the liquid temperature drop.

[0164] In one embodiment, referring to Figure 24 、 Figure 25 As shown, it further includes a three-way joint 19. The three-way joint 19 includes a first interface 191, a second interface 192, and a third interface 193; the first interface 191 is connected to the first liquid outlet 122; the second interface 192 is connected to the fourth liquid inlet 1543; the third interface 193 is connected to the third liquid outlet A2.

[0165] In one embodiment, referring to Figure 24 、 Figure 25As shown, the first liquid outlet 122 is connected to the first interface 191 through the fifth pipeline 178; the fourth liquid inlet 1543 is connected to the second interface 192 through the sixth pipeline 179; the fourth liquid outlet 1544 is connected to the third liquid inlet A1 through the seventh pipeline 180; the third liquid outlet A2 is connected to the third interface 193 through the eighth pipeline 181;

[0166] Wherein, a water pump 21 is arranged on the sixth pipeline 179, and the water pump 21 is electrically connected to the control component; when the water pump 21 works, the liquid in the liquid storage tank 12 flows through the third cooling plate 154 through the fifth pipeline 178 and the sixth pipeline 179 and then flows into the first protective gear A through the seventh pipeline 180, and the liquid in the first protective gear A flows through the third cooling plate 154 through the eighth pipeline 181 and the sixth pipeline 179 and then flows into the first protective gear A again through the seventh pipeline 180; when the water pump 21 is closed, the liquid in the first protective gear A flows into the liquid storage tank 12 through the eighth pipeline 181 and the fifth pipeline 178.

[0167] It should be noted that after the water pump 21 is closed, due to the relatively high pressure in the first protective gear A, the liquid in the first protective gear A will flow into the liquid storage tank 12 through the eighth pipeline 181 and the fifth pipeline 178.

[0168] In one embodiment, a liquid level detector 61 is further arranged in the liquid storage tank 12, and a temperature sensor 62 is arranged on the seventh pipeline 180 (see Figure 24 shown) or the eighth pipeline 181 (see Figure 25 shown), and the liquid level detector 61 and the temperature sensor 62 are both electrically connected to the control component.

The throttling device is arranged on the second pipeline connection section extending out of the heat exchanger 15 to connect to the condenser 13; the throttling device can be a capillary pipeline. After the second pipeline connection section extends out of the heat exchanger 15, there is a tendency for the pipeline diameter to decrease to form a capillary pipeline. Preferably, the diameter is reduced to 1 / 3 - 1 / 6 of the original pipeline diameter; the throttling device can also be a throttle valve or other throttling and pressure-reducing devices.

[0172] It should be noted that the liquid refrigerant after heat dissipation passes through a capillary pipeline with a smaller diameter. Due to the smaller cross-sectional area of the pipeline, the flow velocity slows down, thereby reducing its pressure and also accompanied by a decrease in temperature; at this time, the liquid refrigerant with a higher pressure just output from the condenser 13 can be depressurized by passing through the capillary pipeline.

[0173] It should be noted that the heat conduction pipe is a copper pipe, and the copper pipe is in a "U" shape and is arranged along the inner wall of the condenser 13 in a curved manner. The high-temperature and high-pressure gaseous refrigerant enters the condenser section. The pipeline of the condenser section is provided with a copper pipe, and the copper pipe absorbs the heat of the gaseous refrigerant and gradually dissipates it into the surrounding environment; at the same time, the working surface of the fan 14 faces the position of the copper pipe in the condenser 13, further enabling the refrigerant to dissipate heat and liquefy. The liquid refrigerant after heat dissipation through the copper pipe and the fan 14 enters the capillary pipeline for pressure reduction, and the liquid refrigerant is transported to the heat exchanger 15 through the second pipeline 172.

[0176] In one embodiment, the first air pipe 174 is further provided with a pressure relief valve 27 and a pressure sensor 63, and the pressure sensor 63 is electrically connected to the control component.

[0177] It should be noted that when the pressure sensor 63 detects that the pressure in the first air pipe 174 is too high, the first air pump 22 can be controlled to be closed and the first solenoid valve 23 can be opened to deflate the first protective gear A; when the first air pump 22 or the first solenoid valve 23 fails, the air can be deflated through the pressure relief valve 27.

[0180] It should be noted that the bracket 31 is arranged on the top of the bottom shell 32 in the housing. The bracket 31 is arranged on the side of the bottom shell facing the liquid storage tank 12; a dust cover 35 is arranged on the side of the housing opposite to the fan 14 to prevent dust and dirt from entering the fan 14; and a joint seat 42 is also arranged at the first groove 321, and the joint seat 42 is used to make the joint 41 detachably connected to the bottom shell 32.
