The invention provides a temperature control device module of an electric blanket. The temperature control device includes heating wires, a control unit and a key switch; the heating wires are buried in the electric blanket; the control unit is fixedly arranged on the electric blanket and comprises a control box body; a substrate is arranged inside the control box body; a plug-in element is assembled and connected on the substrate; a thyristor element is assembled on the substrate and is electrically connected with the plug-in element; a microprocessor is also assembled on the substrate and is electrically with the thyristor element; the substrate, the plug-in element, the thyristor element and the microprocessor are jointly form a module; the key switch and the control unit are arranged separately and are fixedly arranged on the electric blanket; the key switch is provided with a switch main body; a substrate is arranged in the switch main body; and a key and temperature display elements are assembled on the substrate in the switch main body. According to the temperature control device module of the electric blanket of the invention, the key switch is arranged on the upper side of the electric blanket, such that a user can readily touch the key switch, and therefore, use convenience can be enhanced; and the user can actually know temperature changes through the temperature display elements arranged on the key switch, such that convenience in temperature adjustment can be improved.
Description
technical field [0001] The invention relates to a temperature control device module for an electric blanket, in particular to a temperature control device module for an electric blanket in which a plurality of control elements are jointly arranged in a control box to form a modular design. Background technique [0002] Such as Figure 6 As shown, the common electric blanket 6 on the existing market is mainly to set a control box 64 between the power line 61 plugged into the mains and the heating line 63 buried in the electric blanket 62, and on the control box 64 Components such as buttons or dials are provided to drive the control circuit installed in the control box 64 through the buttons or dials to adjust the current size of the input commercial power and then output it to the heating wire 63, so as to control the temperature in the heating wire 63. The purpose of the heating wire to emit heat energy. see also Figure 7 As shown, another kind of electric blanket 7 has ...
