[0032] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0033] Combination Figure 1-Figure 6As shown, the utility model discloses a portable hot and cold massager, which includes a housing 1, inside which a convection chamber 101 and two battery compartments 102 symmetrically located on two opposite sides of the convection chamber 101 are formed. Specifically, the housing 1 includes a lower housing 11 and an upper housing 12 that are relatively assembled and connected, and the convection chamber 101 is formed by the lower housing 11 and the upper housing 12; the lower side surface of the lower housing 11 is the first positive side surface 110 of the housing 1, and correspondingly, the upper side surface of the upper housing 12 is the second positive side surface 120 of the housing, and the first positive side surface 110 and the second positive side surface 120 are two opposite positive side surfaces of the housing 1.

[0034] A first convection groove 103 is provided on the second front side surface 120 of the upper shell 12, and a second convection groove 104 is provided on at least two vertical side surfaces between the first front side surface 110 and the second front side surface 120 on the outer shell 1, that is, at least two vertical side surfaces of the lower shell 11 and the upper shell 12 are respectively provided with a second convection groove 104.

[0035] The thermoelectric cooling sheet 3 is disposed on the first front side surface 110 of the lower housing 11. Specifically, the massage part 4 is exposed on the first front side surface 110 of the lower housing 11, and the thermoelectric cooling sheet 3 is attached to the inner side surface of the massage part 4.

[0036] A power supply battery 2 is arranged in the battery compartment 102 , and the power supply battery 2 supplies power to the thermoelectric cooling sheet 3 .

[0037] The portable hot and cold massager also includes a heat dissipation module 5, which is assembled in the convection chamber 101 and connected to one side of the thermoelectric cooling sheet 3 to provide heat dissipation or cooling for the thermoelectric cooling sheet 3. The convection chamber 101 forms convection with the external air through the first convection groove 103 and the second convection groove 104, thereby improving the heat dissipation or cooling efficiency of the heat dissipation module 5, and further improving the cooling or heating efficiency of the thermoelectric cooling sheet 3.

[0038] The portable hot and cold massager further comprises a control circuit board 6 which is electrically connected to the thermoelectric cooling sheet 3 to control the operation of the thermoelectric cooling sheet 3 .

[0039] The portable hot and cold massager controls the circuit board 6 to make the thermoelectric cooling sheet 3 work in the cooling mode or the heating mode, thereby making the contact side of the thermoelectric cooling sheet 3 and the massage part 4 generate cooling or refrigeration, and providing cold compress massage or hot compress massage to the outside through the massage part 4.

[0040] The present application takes into account that a user may hold the portable hot and cold massager with one hand to fit the massage part 4 to the body position that needs massage to provide cold massage or hot massage. In order to avoid the palm of one hand completely blocking the first convection groove 103 or completely blocking the second convection groove 104, so that the first convection groove 103 and the second convection groove 104 cannot work together and affect the working performance of the thermoelectric cooling plate 3, the present application has made the following improvements: First, the area of ​​the first convection groove 103 is set to at least 2 / 3 of the area of ​​the second positive side surface of the shell, so that the palm cannot completely block the first convection groove 103; second, the second convection groove 104 is set on at least two of the vertical sides of the lower shell 11 and the upper shell 12, so that the second convection groove 104 located on different vertical sides cannot be blocked at the same time when it is held with one hand.

[0041] Furthermore, a plurality of concave areas 121 are provided on the second front side surface 120 of the upper shell 12, and the first convection grooves 103 are provided in the concave areas 121; and there are isolation bars 122 whose top surfaces are higher than the first convection grooves 103 between adjacent concave areas 121. With such a structure, when the portable hot and cold massager is used by one hand, the isolation bars 122 with higher top surfaces come into contact with the hand, so that there is a gap between the hand and the first convection grooves 103 for smooth airflow, thereby preventing the hand from blocking the first convection grooves 103.

[0042] The portable hot and cold massager symmetrically arranges two battery compartments 102 on two opposite sides of the convection chamber 101, and the power supply battery 2 is arranged in the battery compartment 102, thereby having the following technical effects:

[0043] 1. Keeping the power supply battery 2 away from the thermoelectric cooling sheet 3 and the heat dissipation module 5 as heat sources can reduce the transfer or radiation effect of heat on the power supply battery 2, making the power supply battery 2 operate at a lower temperature, with more stable operating performance and safe and reliable use.

[0044] 2. By arranging the two battery compartments 102 symmetrically relative to the convection chamber 101, the weight of each part of the portable hot and cold massager is relatively balanced, which is conducive to keeping the massage part 4 in stable contact with the body skin during the massage process, thereby improving the user experience.

[0045] A handle portion 13 is provided on both sides of the housing 1, and a battery compartment 102 is disposed in each handle portion 13. The handle portions 13 are provided so that one of the handle portions 13 can be held by one hand for use, or one of the handle portions 13 can be held by both hands for use.

[0046] Furthermore, there is a mounting groove 105 between the handle portion 13 and the vertical side surface of the housing 1 for matching with the fixing belt 9, and the mounting groove 105 is located between the battery compartment 102 and the convection chamber 101. The provision of the mounting groove 105 has at least the following technical effects: first, the heat in the convection chamber 101 is isolated from being transferred to the battery compartment 102 through the mounting groove 105, thereby reducing the impact on the power supply battery 2 in the battery compartment 102; second, the mounting groove 105 is matched with the fixing belt 9, for example, the fixing belt 9 is provided through the mounting groove 105, or the end of the fixing belt 9 is fixedly connected to the mounting groove 105, so that the portable hot and cold massager can be tied to a certain part of the body using the fixing belt 9, without having to be held by hand, thereby expanding the use of the portable hot and cold massager, see Figure 7 shown.

[0047] In addition, there are two power supply batteries 2, and one power supply battery 2 is provided in each of the two battery compartments 102, so that the two power supply batteries 2 are evenly and symmetrically distributed in the two battery compartments 102, making the center of gravity of the portable hot and cold massager more reasonable, so as to facilitate the massage part 4 to maintain a stable and reliable fit with the body skin.

[0048] Of course, the number of power supply batteries 2 can be one and it can be set in one of the battery compartments 102, and the control circuit board 6 or configuration block can be set in the other battery compartment 102, which can also allow the portable hot and cold massager to have an overall reasonable center of gravity structure.

[0049] In addition, the heat dissipation module 5 is fixedly assembled inside the first front side surface 110 of the lower housing 11 , so that the thermoelectric cooling sheet 3 is pressed and fixed between the massage part 4 and the heat dissipation module 5 .

[0050] Specifically, the heat dissipation module 5 includes a bracket lower seat 51, a fan 52 installed on the bracket lower seat 51, and a radiator 53 limitedly fixed between the bracket lower seat 51 and the fan 52. The radiator 53 includes a plurality of heat sinks, and there are a plurality of transverse convection gaps 531 and a plurality of longitudinal convection gaps 532 between adjacent heat sinks.

[0051] In addition, the heat dissipation module 5 also includes a bracket upper seat 54 installed on the bracket lower seat 51; the control circuit board 6 is fixed on the bracket upper seat 54 so that the control circuit board 6 is located between the heat dissipation module 5 and the first convection groove 103, and the control circuit board 6 is provided with an air groove 61, and the air groove 61 is arranged at the positive projection of the heat dissipation module 5 to coincide with the air inlet of the fan 52.

[0052] The operation of the heat dissipation module 5 is described by taking the fan 52 as an air suction fan as an example. When the fan 52 is working, the cold air outside the housing 1 is sucked in from the first convection groove 103, and the cold air flows through the air groove 61 of the control circuit board 6 to first dissipate the heat of the control circuit board 6 to ensure the stable operation of the control circuit board 6, and the cold air is blown to the radiator 53 through the fan 52, and flows through a plurality of transverse convection gaps 531 and a plurality of longitudinal convection gaps 532 to form a hot air flow for heat exchange, and the hot air flow is discharged from the second convection grooves 104 on each vertical side of the housing 1.

[0053] The second front side surface 120 of the upper housing 12 is provided with a plurality of button holes 123; the control circuit board 6 is provided with a plurality of operation buttons 62, the ends of the operation buttons 62 are exposed through the button holes 123. The user can select the working mode of the portable hot and cold massager through the operation buttons 62.

[0054] For example, when the portable hot and cold massager is in heating mode, the massage part 4 generates a hot compress temperature of 30-45 degrees Celsius. At this time, the side of the thermoelectric cooling sheet 3 in contact with the massage part 4 is the heating surface, and the side of the thermoelectric cooling sheet 3 in contact with the radiator 53 is the cooling surface. The cooling surface dissipates heat through convection with the outside air through the heat dissipation device 5 to achieve thermal equilibrium.

[0055] For example, when the portable rotary hot and cold massager is in cooling mode, the massage part 4 generates a cold compress temperature of 5-15 degrees Celsius. At this time, the side of the thermoelectric cooling sheet 3 in contact with the massage part 4 is the cooling surface, and the side of the thermoelectric cooling sheet 3 in contact with the radiator 53 is the heat dissipation surface. The heat dissipation surface dissipates heat through convection between the heat dissipation device 5 and the outside air.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
