[0020] The specific embodiments of the utility model are further described below. It should be understood that the description of the utility model here is not used to limit the protection scope of the utility model.

[0021] As Figures 1 to 4 shown, it is a structure schematic view of a portable mute cold and hot compress machine provided by the utility model. The portable mute cold and hot compress machine comprises a main body 10, a temperature control assembly 20 arranged on the main body 10, a temperature control bag 30 accommodated in the main body 10 and a cold and hot compress pad 40 arranged on one side of the main body 10. It is conceived that the portable mute cold and hot compress machine should also comprise some other functional assemblies, such as assembly assemblies, connecting assemblies, electrical connecting assemblies and the like, which are all prior art known by those skilled in the art, and will not be described here.

[0022] The main body 10 comprises a shell 11, a receiving cavity 12 arranged on one side of the shell 11, at least one bandage 13 fixedly connected to the edge of the shell 11, and a flip cover 14 arranged on one side of the receiving cavity 12.

[0023] The shell 11 can be made of heat insulation material and comprises a body 111 and a rim 112 arranged along the outer contour of the body 111. The body 111 is used to arrange the temperature control assembly 20 so as to facilitate mounting of the temperature control assembly 20 on the body 111. Specifically, a plurality of insertion holes 113 are formed on the body 111 and used to insert and fix the semiconductor refrigerating sheet 21, and the size and shape of the insertion holes 113 are consistent with those of the semiconductor refrigerating sheet 21. The shape of the body 111 can be adapted to the shape of the human body, thereby facilitating wearing. In the embodiment, the shell 11 is designed in the shape of a human face. It is conceivable that the shell 11 can also be designed to adapt to any shape of the foot, hand, or leg according to actual needs. The rim 112 is arranged on one side of the body 111 and surrounds the outer contour of the body 111, thereby forming the receiving cavity 12 on one side of the body 111. The rim 112 and the body 111 can be integrally formed.

[0024] The receiving cavity 12 is used to accommodate the temperature control bag 30 and the temperature control assembly 20, thereby facilitating mounting of the temperature control bag 30 and the temperature control assembly 20 on the shell 10.

[0025] The two ends of the bandage 13 are fixedly connected to the two sides of the shell 11, thereby facilitating wearing on the human body when the cold and hot compress machine is used. Specifically, a hanging ring structure can be arranged on the two sides of the body 111 to facilitate mounting of the bandage 13, or when the shell 11 is made of plastic, the bandage 13 can be directly heat-pressed and fixed on the body 111. According to use requirements, two or more bandages 13 can be arranged side by side, thereby improving the wearing stability of the cold and hot compress machine. The bandage 13 can be made of elastic material such as elastic rope, so as to improve the size adaptability of the bandage 13. Preferably, an adjusting buckle or other workpiece capable of adjusting the length can be further arranged on the bandage 13 to adjust the length of the bandage 13.

[0026] The flip cover 14 comprises a cover body 141, a connecting piece 142 arranged on one side of the cover body 141, and a fixing piece 143 arranged on the other side of the cover body 141.

[0027] The cover body 141 is arranged in matching with the receiving cavity 12 and used to close the receiving cavity 12 when in use, thereby fixing the temperature control bag 30 in the receiving cavity 12.

[0028] The connecting member 142 is used to reversibly connect the cover 141 to the shell 11, so as to facilitate the opening and closing of the flip cover 14. The connecting member 142 can be made of soft rubber, one side of which is heat-pressed to the shell 11, and the other side is heat-pressed to the flip cover 14, so as to connect the flip cover 14 and the shell 11 together.

[0029] Therefore, the fixing member 143 is arranged on the side of the cover 141 opposite to the connecting member 142. The fixing member 143 comprises a card 1431 fixed to one side of the cover 141, and a card slot 1432 arranged on the shell 11. The card 1431 and the card slot 1432 can be in interference fit, so that when the flip cover 14 is closed, one side of the card 1431 is inserted into the card slot 1432, so that the cover 141 and the shell 11 are buckled together. When it is needed to be opened, the card 1431 can be pulled out of the card slot 1432 by force, so as to open the cover 141.

[0030] The temperature control assembly 20 is used to cool or heat the cold and hot compress pad 40, which comprises a plurality of semiconductor refrigeration pieces 21 fixed in the accommodating cavity 12, and at least one refrigeration piece driving assembly 22 arranged on the shell 11.

[0031] The semiconductor refrigeration sheet 21 can be arranged along the four sides of the accommodating cavity 12, so that multiple semiconductor refrigeration sheets 21 can refrigerate or heat the cold compress pad 40 from different directions, so that the semiconductor refrigeration sheet 21 can quickly adjust the temperature of the cold compress pad 40 while making the temperature of each part of the cold compress pad 40 more uniform to avoid local overcooling or overheating when the temperature is conducted in one direction. The semiconductor refrigeration sheet 21 itself is a prior art, and the semiconductor refrigeration sheet 21 can change the heat transfer direction of the thermocouple by changing the direction of the current, thereby achieving the effect of refrigeration or heating. Specifically, when the power supply is connected to the semiconductor refrigeration sheet 21, and the current flows from the side of the N-type semiconductor to the side of the P-type semiconductor, the side of the P-type semiconductor absorbs heat and becomes hot to form a hot surface, and the temperature of the side of the N-type semiconductor decreases to form a cold surface, thereby generating a temperature difference between the cold surface and the hot surface, so that the side of the cold surface of the semiconductor refrigeration sheet 21 has a refrigeration effect, and the side of the hot surface has a heating effect. It is conceivable that as long as the temperature on one side of the semiconductor refrigeration sheet 21 remains constant, the temperature on the other side can remain constant, thereby achieving the effect of continuous refrigeration or heating. Further, the temperature difference between the two sides of the semiconductor refrigeration sheet 21 can be controlled by adjusting the size of the current of the driving assembly 22 according to the demand of the application temperature, so that the temperature difference between the cold surface and the hot surface of the semiconductor refrigeration sheet 21 is controlled within a certain range, so that the refrigeration temperature of the semiconductor refrigeration sheet 21 can be maintained within the optimal application temperature range. In addition, since the semiconductor refrigeration sheet has the characteristics of no noise and no vibration, the cold compress machine will not make noise due to the operation of the temperature control assembly 20. Multiple semiconductor refrigeration sheets 21 are fixedly inserted into the plug-in hole 113 provided in the body 111 and penetrate the body 111, so that when the portable silent cold compress machine is assembled and used, the side of the semiconductor refrigeration sheet 21 facing the cold compress pad 40 can be in direct contact with the cold compress pad 40, thereby providing the cold compress pad 40 with a temperature for cold compress or hot compress of the human body. The side of the semiconductor refrigeration sheet 21 facing the temperature control bag 30 can be in sufficient contact with the temperature control bag 30 to achieve effective cooling. The semiconductor refrigeration sheet 21 and the plug-in hole 113 can be fixed by means of glue or the like. The semiconductor refrigeration sheet 21 is arranged between the cold compress pad 40 and the temperature control bag 30, and when the portable silent cold compress machine is used, the temperature of the cold compress pad 40 during cold compress or hot compress can be controlled by controlling the semiconductor refrigeration sheet 21, thereby improving the user experience.

[0032] The refrigeration piece driving assembly 22 is electrically connected with the semiconductor refrigeration piece 21, and is used for providing power supply for the semiconductor refrigeration piece 21 and controlling the semiconductor refrigeration piece 21 to work. The refrigeration piece driving assembly 22 should adopt a power supply matched with the rated working voltage of the semiconductor refrigeration piece 21, for example, when the working voltage of the semiconductor refrigeration piece 21 is 12V, a 12V power supply should be selected. Further, two refrigeration piece driving assemblies 22 can be respectively arranged to separately control the refrigeration or heating of the semiconductor refrigeration piece 21. When only one refrigeration piece driving assembly 22 is arranged, the refrigeration piece driving assembly 22 can change the direction of current by using a bipolar switch, such as a double-pole double-throw switch, so as to change the refrigeration end and the heat dissipation end of the semiconductor refrigeration piece 21, thereby adjusting the effect of the cold and hot compress machine. It is conceived that the refrigeration piece driving assembly 22 should also include a wire for connecting the semiconductor refrigeration piece 21 with a power supply, a switch for controlling the connection state of the semiconductor refrigeration piece 21 with the power supply, a temperature sensor for monitoring the working temperature, a temperature controller, a software control system for controlling the circuit and other related functional components. According to actual needs, the software control system can control each semiconductor refrigeration piece to work independently or control multiple semiconductor refrigeration pieces to work synchronously. When the software control system controls each semiconductor refrigeration piece to work independently, each semiconductor refrigeration piece can provide different temperatures, thereby meeting the more detailed temperature requirements of users, because the temperatures that can be accepted by different regions of the human body, such as the face, are different, for example, when cold compress is performed, the temperature that can be accepted by the eyes is much lower than the temperature that can be accepted by the cheeks. When the software control system controls multiple semiconductor refrigeration pieces to work together, it can provide convenience for large-area cold compress or hot compress, such as legs or back, etc. As for the software control system, as long as the control mode of the present application is understood by those skilled in the art, the desired control program can be written by using existing computer languages to complete the corresponding control, and therefore the control mode will not be described in detail here.

[0033] The temperature control bag 30 is shaped to fit the shape of the shell 11, so as to be accommodated in the accommodating cavity 12. The temperature control bag 30 and the shell 11 sandwich the semiconductor refrigeration sheet 21 therebetween, and are used to absorb and hold the heat on the side of the semiconductor refrigeration sheet 21 opposite to the cold compress pad 40. The temperature control bag 30 can replace the heat sink and fan of the conventional semiconductor refrigerator, so that the temperature difference between the two sides of the semiconductor refrigeration sheet 21 can be kept within a certain range for a long time when the temperature control assembly 20 is working, so that the working end of the semiconductor refrigeration sheet 21 can maintain stable refrigeration effect for a long time. The temperature control bag 30 can be an independent component that can be cooled. It can be made of water gel, cold compress gel pad, water bag and other materials that can easily absorb heat. Before use, the temperature control bag 30 can be placed in a household or commercial ice chest to freeze into an ice bag, so as to facilitate use, convenient to carry and take, and thus the user can move when using the cold compress machine, improving the user experience. In order to avoid the temperature of the temperature control bag 30 being directly transmitted to the cold compress pad 40 through the shell 11, thereby affecting the temperature of the cold compress pad 40, the shell 11 can be made of heat insulating material, such as heat insulating plastic, so as to prevent the temperature control bag 30 from directly affecting the temperature of the cold compress pad 40, and at the same time, the temperature control bag 30 can be kept warm, so that the temperature control bag 30 can maintain a frozen state for a long time.

[0034] The cold compress pad 40 is arranged on the side of the shell 11 opposite to the accommodating cavity 12, and is made of skin-friendly materials such as silica gel and non-woven fabric, so as to improve the comfort of the cold compress machine when worn, and the cold compress pad 40 can also protect the human skin. When in use, the semiconductor refrigeration sheet 21 operates to cool or heat the cold compress pad 40, so that the cold compress pad 40 can maintain a certain temperature range to cool or heat the human body, and the cold compress pad 40 avoids direct contact of the human body with the shell 10, thereby avoiding discomfort. The cold compress pad 40 is a prior art, and will not be described here.

[0035] Compared with the prior art, the portable mute cold and hot compress machine has the temperature control assembly 20 arranged on the main body 10, the temperature control assembly 20 comprises a plurality of semiconductor refrigerating sheets 21, and the refrigerating sheet driving assembly 22 is arranged on the main body 10 and used for driving the semiconductor refrigerating sheet 21 to refrigerate or heat the cold and hot compress pad 40. The semiconductor refrigerating sheet 21 has no noise and vibration during work, so that the cold and hot compress machine can work silently, the temperature difference between the two sides of the semiconductor refrigerating sheet 21 can be maintained within a certain range by replacing the temperature control bag 30, so that the cold and hot compress machine can keep the sticking temperature within a certain range, such as 4-10 degrees Celsius, for a longer time. Meanwhile, the temperature control bag 30 is an independent component, which can be placed in a household or commercial freezer to condense into an ice bag before use, so as to facilitate the use of users, and is convenient to carry and take, and then when the cold and hot compress machine is used, the user can move, and the use experience of the user is improved.

[0036] The above is only a preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement within the utility model spirit is covered in the claim range of the utility model.
