Description

Technical Field

[0001] The present invention relates to a hot and cold compress device, comprising a main unit, a hot and cold compress belt, and an electric hot compress belt. The main unit has a cold water chamber and a hot and cold water chamber. The hot and cold compress belt has a separate cold water channel and a separate hot and cold water channel, and can be interchangeably connected to the main unit with the electric hot compress belt to efficiently perform functions such as rapid cold compress, hot and cold compress switching, or rapid hot compress. Background Art

[0002] The hot and cold compress device uses cooling and heating elements as the temperature generation source, and uses cold water or hot water as the heat transfer medium. The cold water and hot water are circulated through a preset pipe to a compress that can be attached to the human body to achieve the effect of cooling or heating the human body.

[0003] Related prior art, such as US Pat. No. 3,967,627 and US Pat. No. 5,344,436, include a water tank and an applicator pad connected by a set of pipes. The water tank is equipped with heating and cooling elements. A peristaltic pump pumps cold or hot water from the water tank through the pipes into the pad, and then circulates it back into the water tank. When the user places the pad against the skin, a cooling or heating effect is achieved.

[0004] Because both the cold and hot compress functions are achieved through the same circulation pipe and water tank in the above-mentioned conventional technology, the temperature adjustment of the cushion is very slow and imprecise. In particular, when the cushion switches from cold compress to hot compress, or from hot compress to cold compress, the user must wait for a considerable time, which is inefficient.

[0005] US20200008975A1 separates the water tank into a cold water reservoir and a hot water reservoir, and uses different pumps to circulate the cold water or hot water through the cushion, respectively, in an attempt to improve the aforementioned inefficiency when switching between cold and hot compresses. However, the cushion in this document still uses the same set of channels for cold and hot water circulation. This means that when the user needs to switch from cold to hot compress, or vice versa, they still have to wait a considerable amount of time.

[0006] US20040068309A1 utilizes a mixing valve to mix hot and cold fluids to a selected temperature before delivering them to a therapy pad, allowing the pad to be adjusted to the desired temperature in a relatively short period of time. However, the pad also utilizes a single set of channels for fluid circulation. Consequently, when the mixed fluid circulates back into the container, whether flowing to the cold or hot water container, the temperature of the original cold or hot water will significantly change, resulting in energy loss and slow and inaccurate subsequent re-mixing and temperature adjustment.

[0007] US20180369015A1 uses another method to switch between hot and cold compress temperatures. This method involves installing a heating element and a cold water channel on the treatment pad. During hot compress application, the cold water flow is stopped and the heating element is activated. This approach aims to quickly switch between hot and cold compresses while maintaining a low temperature in the cooling system's cold water reservoir. However, when the heating element is activated, cold water remains in the treatment pad. This means the heating element must gradually heat the remaining cold water to the selected temperature before the hot compress can be applied. This prevents the application of a quick hot compress.

[0008] The main drawback of the aforementioned known technologies is that the hot and cold compress switching function is not perfect. In view of this, the inventors have improved the main unit and the compress band with the three major functions of rapid cold compress, cold and hot compress switching, and rapid hot compress as the guide, in order to allow users to more flexibly and accurately present the set cold and hot compress temperatures, thereby improving the comfortable user experience. Summary of the Invention

[0009] The present invention aims to provide a hot and cold compress device with a dual water channel design. The device comprises a main unit, a cold water chamber and a hot and cold water chamber, each isolated from each other. The device also includes at least two flexible compress bands that can be interchangeably connected to the main unit. The main unit's cold water chamber is capable of rapid cooling, while the hot and cold water chambers are capable of rapid cooling or heating. The two compress bands include a hot and cold water compress band and an electric heating compress band, each of which has an independent cold water channel and a hot and cold water channel. By interchangeably attaching the two compress bands to the main unit, functions such as rapid cooling, switching between hot and cold compresses, or rapid heating can be achieved.

[0010] To achieve the above objectives, the present invention provides a hot and cold compress device with a dual water channel design, comprising a main unit and at least two compress bands.

[0013] The hot and cold compress band includes a sheet-shaped hot and cold compress body, which includes a uniform temperature compress surface that can be attached to the affected part of the human body, and a back surface opposite to the uniform temperature compress surface. A cold water channel and a hot and cold water channel are provided between the uniform temperature compress surface and the back surface. The cold water channel and the hot and cold water channel are arranged in a winding shape and are pluggably connected to the pipe joint of the main body through a set of cold water pipes and a set of hot and cold water pipes.

[0014] The electric heating compress belt comprises a sheet-shaped heating compress body, which comprises a uniform temperature compress surface that can be attached to an affected part of a human body, a back surface opposite to the uniform temperature compress surface, an electric heating plate disposed between the uniform temperature compress surface and the back surface, and a flexible extension belt disposed at the edge of the electric heating compress belt; wherein the rear end of the flexible extension belt is provided with a plug end and a USB transmission line electrically connected to the electric heating plate, respectively, relative to the pipe joint and the USB plug port, so that the electric heating compress belt can be plugged and unplugged into the pipe joint positioned on the host, and after the USB transmission line is plugged into the USB plug port, it is electrically connected to the electronic control system of the host;

[0015] During rapid cold compress, the cold water pipe and the hot and cold water pipe of the hot and cold water compress belt are connected to the pipe joint of the main unit, and through the settings of the operation interface, the main unit board drives the cooling module and the heating and cooling module to simultaneously cool the stored water in the cold water chamber and the hot and cold water chamber, and through the opening and closing of the cold water pump, the hot and cold water pump and the solenoid valve, the cold water in the cold water chamber and the hot and cold water chamber is pumped through the pipe joint, the cold water pipe and the hot and cold water pipe to the hot and cold compress body for circulation, and then a rapid cold compress is performed through the temperature-uniform compress surface;

[0016] When switching between hot and cold compresses, the cold water pipe and the hot and cold water pipe of the hot and cold compress body are connected to the pipe joint of the main unit. Through the settings of the operation interface, the main unit board can selectively drive the heating and cooling module to heat the stored water in the hot and cold water chambers, and / or drive the cooling module to cool the stored water in the cold water chamber. By opening and closing the hot and cold water pumps, the solenoid valves and / or the cold water pumps, the hot water and / or cold water pumps are respectively pumped into the hot and cold water channels and / or the cold water channels of the hot and cold water compress belt for circulation, so that the hot and cold compress body can switch between hot and cold compresses; and

[0017] When performing a quick hot compress, the hot and cold water compress belt is removed from the host, and the flexible extension belt of the electric heating compress belt is respectively plugged into the pipe joint and USB plug port of the host through the plug end and the USB transmission line. Through the setting of the operation interface, the host board can transmit power to the electric heating plate through the USB plug port and the USB transmission line to generate heat, and perform a quick hot compress through the uniform temperature compress surface of the hot compress body.

The air pump is arranged in the accommodating space and is electrically connected to the main board. When switching between hot and cold compresses, the main board can selectively drive the air pump to inject air into the cold water pipe or the hot and cold water pipes, so that the cold water or hot water in the cold water channel or the hot and cold water channel in the hot and cold compress body is pushed out and emptied and then flows back to the corresponding cold water chamber or the hot and cold water chamber, thereby accelerating the efficiency of switching between hot and cold compresses.

[0021] During implementation, the shell of the host is further provided with a signal interface electrically connected to the main board outside the accommodating space. The cold and hot compress body and the hot compress body are respectively provided with a temperature sensor.

[0022] During implementation, the hot and cold compress body is formed by overlapping and welding an upper flexible substrate and a lower flexible substrate using high-temperature welding technology. The cold water channel and the hot and cold water channel are located between the upper and lower flexible substrates, and the lower flexible substrate has a bottom surface. The heating plate is attached to the bottom surface of the lower flexible substrate, and the temperature-uniform compress surface is attached to a bottom surface of the heating plate. The temperature-uniform compress surface is composed of a composite film sheet with graphene or a film sheet with a graphene coating layer; and an insulation sheath is covered on the upper flexible substrate to form the back side of the hot and cold compress body.

[0023] During implementation, the backs of the cold and hot compress body and the hot compress body are respectively provided with fixing parts that can be tied and fixed to the affected part of the human body. The fixing parts are Velcro, fixing straps or fixing straps with multiple pressurized airbags.

[0024] During implementation, the refrigeration module includes a cooling chip having a cooling surface and a heat dissipation surface opposite to the cooling surface. The cooling surface is stacked with a first temperature conduction fin extending into the cold water chamber, and the heat dissipation surface is stacked with a heat dissipation fin. A fan is provided above the heat dissipation fin to blow air to the heat dissipation fin, and the housing is provided with a plurality of heat dissipation holes around and above the fan.

[0025] During implementation, the heating and cooling module is composed of a thermoelectric cooler (TEC) that uses current reversal to switch between heating and cooling, or a cooling chip that can cool the water stored in the hot and cold water chambers and a heating plate that can heat the water stored in the hot and cold water chambers.

[0026] During implementation, the host's electronic control system is further provided with a power input port electrically connected to the mainboard, and a wireless transmission module, wherein: the power input port can be electrically connected to an external power source, and the power is output to the USB plug port through the mainboard; the wireless transmission module can transmit signals to an external mobile device, and the external mobile device can remotely control the temperature of the dressing through the wireless transmission module.

[0043] like Figures 1 to 3 As shown, the present invention provides a hot and cold compress device with a dual water channel design, which includes a main unit 1 and at least two compress strips. The two compress strips are flexible and can be attached and fixed to the surface of the affected part of the human body respectively. One of the two compress strips is a hot and cold water compress strip 2, and the other is an electric hot compress strip 3. The hot and cold water compress strips 2 and the electric hot compress strips 3 can be attached and fixed to the surface of the affected part of the human body respectively, and can be replaceably connected to the main unit 1 to efficiently perform rapid cold compress, cold and hot compress switching or rapid hot compress functions.

[0044] As shown, the main unit 1 includes a housing 10, which is divided into a cold water chamber 20, a hot and cold water chamber 30, and an electronic control system 40. In the figure, the housing 10 of the main unit 1 is roughly rectangular, with the cold water chamber 20 and the hot and cold water chamber 30 located at opposite ends of the housing 10. The housing 10 defines a receiving space 11 between the cold water chamber 20 and the hot and cold water chamber 30 to accommodate the electronic control system 40.

[0045] The cold water chamber 20 is provided with a set of internal pipes 21 and a refrigeration module 22 . The refrigeration module 22 is electrically connected to the set of electronic control systems 40 and can cool the cold water or room temperature water stored in the cold water chamber 20 .

[0046] The hot and cold water chamber 30 is provided with a set of internal pipes 31 and a heating and cooling module 32 . The heating and cooling module 32 is electrically connected to the set of electronic control systems 40 and can cool or heat the water stored in the hot and cold water chamber 30 .

[0047] In the figure, the heating and cooling module 32 is composed of a thermoelectric cooler (TEC) that utilizes reverse current switching to heat or cool. In practice, it is not excluded that the heating and cooling module 32 is composed of a cooling chip and a heating plate (not shown), so that the heating and cooling module 32 can selectively heat or cool the water stored in the hot and cold water chamber 30.

[0048] The electronic control system 40 includes an operation interface 41 disposed outside the housing 10, and a mainboard 42, a cold water pump 43, a hot and cold water pump 44, and a set of solenoid valves 45, which are disposed within the accommodating space 11. The operation interface 41, the cold water pump 43, the hot and cold water pump 44, the solenoid valves 45, and the aforementioned cooling module 22 and heating and cooling module 32 are electrically connected to the mainboard 42.

[0049] The cold water pump 43 is connected to the solenoid valve 45 and the cold water chamber 20 via corresponding internal pipes 21, and the hot and cold water pump 44 is connected to the solenoid valve 45 and the hot and cold water chamber 30 via corresponding internal pipes 31. In addition, the housing 10 of the host 1 is provided with a plurality of pipe joints 12 connected to the cold water pump 43 and the hot and cold water pump 44, respectively, outside the accommodating space 11, and at least one USB port 13 electrically connected to the motherboard 42.

[0050] like Figure 2 、 Figure 4 As shown, the hot and cold water compress strip 2 includes a hot and cold compress body 50 that is generally in the form of a sheet. The hot and cold compress body 50 includes a uniform temperature compress surface 51 that can be attached to the affected part of the human body, and a back surface 52 opposite to the uniform temperature compress surface 51. A cold water channel 53 and a hot and cold water channel 54 that are isolated from each other and independent of each other are provided between the uniform temperature compress surface 51 and the back surface 52, and the cold water channel 53 and the hot and cold water channel 54 are respectively arranged in a winding shape within the hot and cold compress body 50.

[0051] Among them, the cold water channel 53 is pluggably connected to the pipe joint 12 of the host 1 through a set of cold water pipes 531, and is connected to the cold water pump 43 and the solenoid valve 45; when the user turns on the cold water pump 43 and the solenoid valve 45 through the operation interface 41 and the host board 42, the cold water pump 43 can pump the stored water in the cold water chamber 20 through the set of pipe joints 12 and the cold water pipes 531 to the cold water channel 53 in the hot and cold compress body 50, and then circulate it back into the cold water chamber 20.

[0052] The hot and cold water channel 54 is pluggably connected to the pipe joint 12 of the main unit 1 via a set of hot and cold water pipes 541, and is then connected to the hot and cold water pump 44 and the solenoid valve 45. When the hot and cold water pump 44 and the solenoid valve 45 are turned on, the hot and cold water pump 44 pumps the water stored in the hot and cold water chamber 30 through the pipe joint 12 and the hot and cold water pipes 541 to the hot and cold water channel 54 in the hot and cold compress body 50, and then circulates the water back into the hot and cold water chamber 30.

[0053] In the figure, the cold water pipes 531 and the hot and cold water pipes 541 are arranged in parallel and are bundled in an insulating sheath, which not only avoids pipeline confusion, but also prevents the cold water pipes 531 and the hot and cold water pipes 541 from losing temperature energy when transporting cold water or hot water.

[0054] like Figure 2 、 Figure 5 As shown, the electric heating compress belt 3 includes a sheet-shaped heating compress body 60, which includes a uniform temperature compress surface 61 that can be attached to the affected part of the human body, a back surface 62 opposite to the uniform temperature compress surface 61, an electric heating sheet 63 arranged between the uniform temperature compress surface 61 and the back surface 62, and a flexible extension belt 64 extending from the edge of the heating compress body 60.

[0055] Among them, the tail end of the flexible extension belt 64 is provided with a plug-in end 65 relative to the multiple pipe joints 12, and a USB transmission line 66 electrically connected to the heating plate 63 is provided relative to the USB plug port 13. When the plug-in end 65 and the USB transmission line 66 are pluggable and plugged into the pipe joint 12 and the USB plug port 13 respectively, the hot compress body 60 can be connected to the host 1, and electrically connected to the electronic control system 40 of the host 1 through the USB transmission line 66 and the USB plug port 13.

[0056] In this way, the electronic control system 40 of the host 1 can provide power to the electric heating plate 63 through the mainboard 42, the USB plug port 13, and the USB transmission cable 66, thereby heating the heating body 60. It should be noted that since the heating body 60 of the electric heating compress strip 3 uses the electric heating plate 63 to generate heat and has no internal water supply pipes, the plug end 65 is connected to the pipe joint 12 only to secure the electric heating compress strip 3 to the host 1 and prevent the USB transmission cable 66 from falling off the USB plug port 13.

[0057] like Figure 1 、 Figure 2 and Figure 6 As shown, through the above-mentioned host 1, hot and cold water compress belt 2 and electric heating compress belt 3, the present invention can efficiently perform three functions: rapid cold compress, cold and hot compress switching, or rapid hot compress. The following details the use of these functions:

[0058] When performing a quick cold compress, the cold water pipe 531 and the cold and hot water pipe 541 of the hot and cold compress belt 2 are respectively connected to the pipe joint 12 of the host 1, and the hot and cold compress body 50 is attached to the affected part of the human body.

[0059] At this time, the user can set the operation interface 41 to make the mainboard 42 drive the cooling module 22 and the heating and cooling module 32 to cool the stored water in the cold water chamber 20 and the hot and cold water chamber 30 at the same time, and respectively open and close the cold water pump 43, the hot and cold water pump 44 and the solenoid valve 45, so that the cold water in the cold water chamber 20 and the hot and cold water chamber 30 is pumped into the hot and cold compress body 50 in sequence through the pipe joint 12, the cold water pipe 531 and the hot and cold water pipe 541, so that the cold water flows through the cold water channel 53 and the hot and cold water channel 54 in the hot and cold compress body 50 at the same time, and is evenly conducted through the uniform temperature compress surface 51, thereby achieving the function of rapid cooling.

[0060] When switching between hot and cold compresses, Figure 1 、 Figure 2 and Figure 7 As shown, the cold water pipe 531 and the cold water pipe 541 of the hot and cold water compress belt 2 are respectively connected to the pipe joint 12 of the host 1, and the hot and cold compress body 50 is attached to the affected part of the human body.

[0061] At this time, the user can set the operation interface 41 to make the mainboard 42 stop the operation of the cooling module 22 and the cold water pump 43, and drive the heating and cooling module 32 to heat the stored water in the hot and cold water chamber 30. After that, by opening and closing the hot and cold water pump 44 and the solenoid valve 45, the hot water in the hot and cold water chamber 30 is allowed to flow through the pipe joint 12 and the hot and cold water pipe 541 to the hot and cold water channel 54 in the hot and cold compress body 50, so that the hot and cold compress body 50 is heated for hot compress.

[0062] After a period of hot compress, the mainboard 42 can stop the heating and cooling module 32 and the hot and cold water pump 44, and at the same time drive the cooling module 22 and the cold water pump 43 to start operating, so that only cold water flows through the hot and cold compress body 50, achieving the effect of switching between hot and cold compress.

[0063] In order to enhance the efficiency of switching between hot and cold compresses, the host 1 of the present invention provides a function of draining the cold water or hot water in the hot and cold compress body 50. In addition to preventing the residual cold water or hot water in the hot and cold compress body 50 from affecting the effect of the hot or cold compress, it can also quickly switch between cold and hot compresses, thereby improving the efficiency of hot and cold compresses.

[0064] The specific implementation method is as follows Figure 2 and Figure 8 As shown, the electronic control system 40 further includes an air pump 46 electrically connected to the main board 42 . The air pump 46 is disposed in the accommodating space 11 and is connected to the cold water pipe 531 and the hot and cold water pipes 541 through the pipe joint 12 .

[0065] When the user wants to switch from a quick cold compress to a hot compress, in addition to stopping the operation of the cooling module 22 and driving the heating and cooling module 32 to heat the water in the hot and cold water chamber 30, the user can also drive the air pump 46 through the pipe joint 12 to inject air into the cold water pipe 531, so that the cold water in the cold water channel 53 is pushed out and emptied and then flows back to the cold water chamber 20, allowing hot water to flow alone in the hot and cold water channels 54 in the hot and cold compress body 50, thereby quickly switching the cold compress state to a hot compress.

[0066] Similarly, if you want to switch from hot compress to cold compress, Figure 9 As shown, the mainboard 42 can drive the air pump 46 to inject air into the hot and cold water pipes 541, pushing out the hot water in the hot and cold water channels 54 of the hot and cold compress body 50 and returning it to the hot and cold water chamber 30, allowing the cold water to flow alone in the cold water channel 53 of the hot and cold compress body 50, thereby achieving the function of switching from hot compress to cold compress.

[0067] At this time, if you want to enhance the effect of cold compress, you can also Figure 6 As shown, the heating and cooling module 32 is driven again to cool the water in the hot and cold water chamber 30, and the cold water is transported to the hot and cold water channels 54 of the hot and cold compress body 50 through the hot and cold water pump 44, so that cold water flows through the cold water channels 53 and the hot and cold water channels 54 in the hot and cold compress body 50 at the same time, thereby enhancing the cold compress effect.

[0068] Furthermore, in order to increase the temperature difference between cold and hot compresses to enhance the switching effect of cold and hot compresses, Figure 2 、 Figure 4 、 Figure 10 As shown, a flexible electric heating plate 55 can be further arranged between the temperature-uniform compress surface 51 and the back surface 52 of the hot and cold compress body 50. The shape of the electric heating plate 55 corresponds to the gap between the cold water channel 53 and the hot and cold water channel 54 and is arranged in a staggered manner. It also has a USB transmission line 56 that can be plugged into the USB plug port 13 of the host 1. When hot water flows in the hot and cold water channel 54, the electric heating plate 55 can obtain power from the host 1 through the USB transmission line 56 to generate heat, so as to improve the efficiency and temperature difference of switching between hot and cold compresses.

[0069] In combination with the foregoing embodiments of the air pump 46, when the cold and hot compress body 50 is assisted in heating by the electric heating sheet 55, the air pump 46 can be driven to push the cold water in the cold water channel 53 back to the cold water cavity 20 after the cold water is exhausted, so that the hot water flows alone in the cold and hot water channel 54 in the cold and hot compress body 50, and then the electric heating sheet 55 is heated, so that the cold compress state can be quickly switched to the hot compress.

[0070] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 11 indicated, when the present application is used for fast hot compress, in addition to the cold and hot compress belt 2 described above, the cold and hot compress belt 2 can be detached from the main machine 1, and the electric heating compress belt 3 is inserted into the main machine 1.

At this time, the uniform heating surface 61 of the hot compress body 60 is attached to the human body, and the electric heating sheet 63 in the hot compress body 60 is controlled to generate heat by the operation interface 41 and the main board 42 of the main machine 1, so that fast hot compress is performed.

[0073] The following further describes other embodiments of the present application:

[0074] As shown in Figure 2 , Figure 4 , Figure 5 indicated, in the implementation, the shell 10 of the main machine 1 is further provided with a signal interface 14 electrically connected to the main board 42 outside the accommodation space 11, and a temperature sensor 57, 67 is respectively arranged on the cold and hot compress body 50 and the hot compress body 60, and the temperature sensor 57, 67 respectively has a signal transmission line 58, 68 which is electrically connected to the signal interface 14 of the main machine 1 in a plug-in manner, so that the temperature of the cold and hot compress body 50 and the hot compress body 60 is transmitted to the main machine 1 in real time, respectively, for the temperature control of the electric control system 40.

[0075] like Figure 10 As shown, during implementation, the hot and cold compress body 50 is formed by overlapping and welding an upper flexible substrate 591 and a lower flexible substrate 592 using high-temperature welding technology. The cold water channel 53 and the hot and cold water channel 54 are located between the upper and lower flexible substrates 591 and 592, and the lower flexible substrate 592 has a bottom surface A.

[0076] In addition, during implementation, an insulating sheath 593 is covered on the upper flexible substrate 591 to form the back side 52 of the hot and cold compress body 50.

[0079] When the cooling surface 222 of the cooling chip 221 cools down, the first temperature conducting fins 224 absorb the heat energy / temperature of the water in the cold water chamber 20 and cool it down. The waste heat is then dissipated outward through the heat dissipation surface 223, the heat dissipation fins 225, the fan 226 and the heat dissipation holes 15.

[0080] As previously described, the heating and cooling module 32 is composed of a thermoelectric cooler (TEC) that utilizes reverse current switching to heat or cool, or is composed of a cooling chip and an electric heater (not shown). The figure shows that when the heating and cooling module 32 is an electric heater 321, its bottom surface 322 may be provided with a second temperature-conducting fin 323 extending into the hot and cold water chamber 30, and its top surface 324 may be provided with a heat dissipation fin 325 and a fan 326. The housing 10 is provided with a plurality of heat dissipation holes 15 around the fan 326 to heat or cool the water stored in the hot and cold water chamber 30 through the second temperature-conducting fin 323, and to dissipate waste heat generated during the operation of the electric heater 321 through the heat dissipation fin 325, the fan 326, and the heat dissipation holes 15.
