Embodiment Construction

[0009] Such as figure 1 As shown, the preferred embodiment of the mouse with heating function of the present invention includes an input circuit 10 and a heating circuit 20 . The input circuit 10 is connected to the heating circuit 20 through a switch S. When the temperature is low, the switch S is closed to turn on the heating function of the mouse. At the same time, the mouse still has an input function. When the temperature is comfortable, the switch S is turned off. The switch S, the mouse only has an input function. The input circuit 10 is a circuit existing in an existing mouse, so it will not be described in detail here.

[0010] The heating circuit 20 includes a switch chip 22 , a thermal diode VD1 as a thermal element, an electric heater EH, a variable resistor RP, a resistor R, a light emitting diode VL and a diode VD2 . The switch chip 22 includes a ground terminal 1, two voltage input terminals 2 and 3, an enable input terminal 4, an overcurrent output terminal 5...

Abstract

The invention relates to a mouse with a heating function, which comprises an input circuit and a heating circuit. The heating circuit comprises a switch chip. A voltage input end of the switch chip is connected with a power end of the input circuit. An electric switch output end of the switch chip is connected with one end of an electric heater. The other end of the electric heater is connected with a ground terminal of the input circuit. A thermo-sensitive element and a resistor are connected in series between the voltage input end of the switch chip and the ground terminal of the input circuit. The thermo-sensitive element and the resistor divide a voltage provided by the power end of the input circuit and then provide the divided voltage to an enable input end of the switch chip to control the switching on and off of the switch chip so as to control the electric heater to work or not. The mouse has a temperature which makes a user comfortable.

Description

technical field [0001] The invention relates to a mouse with a heating function and a heating circuit thereof. Background technique [0002] When using a computer in daily work, the most contact with the human body is the mouse. In winter or the day with lower air temperature, after using the mouse of computer for a period of time, people often feel the palm of the hand is cold due to the lower ambient temperature, thereby making the computer user feel uncomfortable when using the mouse. Contents of the invention [0003] In view of this, it is necessary to provide a mouse with heating function. [0004] It is also necessary to provide a heating circuit applied to the above-mentioned mouse. [0005] A mouse with a heating function, comprising an input circuit and a heating circuit, the heating circuit includes a switch chip, the voltage input terminal of the switch chip is connected with the power supply terminal of the input circuit, and the power supply terminal of the...
