[0018] The utility model provides a handheld cold and hot compress beauty instrument.

[0019] like Figures 1 to 4 As shown, in one embodiment of the utility model, the handheld hot and cold compress beauty instrument includes a main control chip 101, a TEC control circuit 102, a TEC module 103, a metal thermal head 104, a temperature sensor 105, a temperature sampling circuit 106, an LDO circuit 107, a rechargeable battery 108, a charging interface 109, a power button 110, a temperature increase button 111 and a temperature decrease button 112. One end of the TEC control circuit 102 is electrically connected to the main control chip 101, and the other end of the TEC control circuit 102 is electrically connected to the TEC module 103. The metal thermal head 104 is connected to the TEC module 103. The rear end of 04 is in contact with the TEC module 103, one end of the temperature sampling circuit 106 is electrically connected to the main control chip 101, the other end of the temperature sampling circuit 106 is electrically connected to the temperature sensor 105, the temperature sensor 105 is in contact with the metal thermal head 104, one end of the LDO circuit 107 is electrically connected to the main control chip 101, the other end of the LDO circuit 107 is electrically connected to the rechargeable battery 108, the charging interface 109 is electrically connected to the rechargeable battery 108, and the power button 110, the temperature increase button 111 and the temperature decrease button 112 are electrically connected to the main control chip 101 respectively.

[0020] Specifically, the main control chip 101 adopts a STC8H1 K08-36I / TSSOP-20 chip.

[0021] Specifically, it also includes a liquid crystal screen 113, which is electrically connected to the main control chip 101. The temperature value can be displayed in real time through the liquid crystal screen, which is more intuitive and clear, so that the user can grasp and adjust the temperature in real time.

[0022] Specifically, it also includes a cooling fan 114 and a boost circuit 115. One end of the boost circuit 115 is electrically connected to the rechargeable battery 108, and the other end of the boost circuit 115 is electrically connected to the cooling fan 114. The boost circuit 115 is electrically connected to an enable pin of the main control chip 101. The cooling fan 114 is arranged on one side of the TEC module 103. The heat generated by the TEC module can be quickly dissipated through the cooling fan, thereby effectively improving the heat dissipation effect of the beauty instrument.

[0023] Specifically, TEC module is short for Thermo Electric Cooler. It is made by using the Peltier effect of semiconductor materials. The so-called Peltier effect refers to the phenomenon that when a direct current passes through a couple composed of two semiconductor materials, one end of the couple absorbs heat and the other end releases heat. Therefore, TEC module is also called thermoelectric cooler.

[0024] Specifically, the heating and cooling principles of the TEC module are:

[0025] The smallest unit of TEC is composed of a pair (group) of N-type and P-type semiconductors plus connecting electrodes (sintering points), which form the cold end and the hot end (see Figure 2 ). Under the action of an external electric field, the current can carry the heat generated in the semiconductor from one end of the TEC to the other, creating a "hot" side and a "cold" side on the TEC. When the current direction is reversed, the hot and cold sides of the TEC will switch (see Figure 3 ). This is the heating and cooling principle of TEC.

[0026] The TEC thermoelectric cooler consists of an internal semiconductor P-pole, a semiconductor N-pole, a conductive metal, and a ceramic substrate for top and bottom temperature exchange. The cooling capacity of a single thermoelectric cooling pair is limited. TEC is generally composed of dozens of cooling pairs (see Figure 4 ). By controlling the direction of the current, the TEC module can be used for both cooling and heating, achieving a temperature control stability better than 0.1°C.

[0027] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
