When the adjustment knob rotates, the display screen does not rotate, and the display effect is more obvious, bringing a better user experience to the user;
[0020] Traditional controllers usually only use one power cord for power supply, and most of them are plug-in power cords. Frequent plugging and unplugging are likely to cause poor contact, and when the power cord is damaged, it cannot be used continuously. Therefore, in this embodiment, a structure with dual power cord power supply is adopted. Specifically, a second power connection line 3 is arranged on the top of the controller 2, and a first power connection line 4 is arranged on the bottom of the controller 2. Both the second power connection line 3 and the first power connection line 4 are electrically connected to the control main board. The first power connection line is the power cord used during normal use. In this embodiment, it is shown at the bottom of the controller. It can be understood that its position can be set at any position on the side of the controller, and its position is not limited. A second power connection line is set on the controller as a standby power connection line. When the first power connection line cannot be used, the second power connection line can be plugged in for use, thus ensuring that the heating pad can be used continuously without increasing the purchase cost due to power cord problems, which is more user-friendly.
[0021] More specifically, a connection port 2-6 is arranged on the top of the controller 2 and is matched with the second power connection line 3. The setting of the connection port is to match the second power connection line. A dust-proof plug can be set on the connection port for dust prevention, and the dust-proof plug is opened to connect the power cord for use when needed.
[0022] More specifically, a temperature indication mark 2-3 is provided on the surface of the controller 2. In this embodiment, the temperature indication mark is provided above the adjustment knob and is a gradient arc structure, forming an indication that gradually increases from left to right, enabling the user to more intuitively and clearly understand the temperature adjustment direction.
[0023] More specifically, a power switch 2-4 and a timing switch 2-5 are also provided on the surface of the controller 2. The power switch 2-4 and the timing switch 2-5 are electrically connected to the control main board. After pressing the power switch, the temperature can be adjusted. At the same time, the timing function can be enabled through the timing switch, and the adjustment is also carried out through the adjustment knob. Compared with the traditional button-type adjustment, the adjustment through the knob is more accurate and has stronger interactivity.
[0024] More specifically, the heating pad 1 includes a surface layer 1-1, a heating layer 1-2, and a heat-insulating bottom layer 1-3. The heating layer 1-2 is disposed between the surface layer 1-1 and the heat-insulating bottom layer 1-3, and heating wires and a control circuit board are provided on the heating layer 1-2. The control circuit board is electrically connected to the control main board.
[0025] The working principle of the present utility model: During use, the second power connection line 3 is an optional backup power connection line.
