The invention is further elucidated with reference to the accompanying drawings.
As shown in fig. 1 to 4, the mobile phone case capable of cooling is detachably mounted on the back of the mobile phone, and includes a case 1, a pressure power generation device, a rectification device, a temperature sensing device and a refrigeration device, all of which are mounted inside the case 1, wherein the pressure power generation device is connected with the refrigeration device through the rectification device, and the temperature sensing device is disposed in a power supply loop of the refrigeration device.
The refrigerating device is a semiconductor refrigerating sheet (as shown in fig. 8), and at the position of the mobile phone CPU corresponding to the inner surface of the shell, the cold end of the refrigerating device is in contact with the shell of the mobile phone after the mobile phone shell is fastened with the back of the mobile phone, and the hot end is bonded with the inner surface of the shell. The wires of the input and output ends are respectively connected with the output end of the temperature sensing device and the input end of the rectifying device.
The pressure power generation device comprises piezoelectric ceramic crystal pieces 7, copper pieces 6 and a lead 8, the upper surface and the lower surface of each copper piece 6 are respectively and fixedly and electrically connected with the piezoelectric ceramic crystal pieces 7, electrode leads of the two piezoelectric ceramic crystal pieces 7 are connected in parallel, and the electrode leads and the lead 8 connected with the copper pieces 6 are connected to the input end of the rectifying device together, and the piezoelectric ceramic crystal pieces 7 are arranged on the inner side of the shell and correspond to the operation position of the handheld part of the mobile phone. The piezoelectric ceramic crystal wafer on the lower surface of the copper sheet is fixed on the inner surface of the shell through industrial glue.
