Embodiment 1

[0033] Embodiment one, such as Figure 1 to Figure 4 As shown, a battery box for a body heater includes a casing 11, a control circuit and a rechargeable battery BT, the rechargeable battery BT is electrically connected to the control circuit, and the control circuit is provided with a charging connector 16, a discharging connector 17, a charging and discharging protection Chip U3, voltage regulator chip U1 and diode D2, the charging connector 16 is divided into two circuits after being isolated by the diode D2, one route charges the rechargeable battery BT through the charging and discharging protection chip U3, and the other route directly discharges through the discharging connector 17, and the charging connector 16 And the discharge joint 17 is arranged on the outer surface of the casing 11 .

[0034] The control circuit is also electrically connected with a single-chip microcomputer U2, a power regulating switch 13 and a power indicator, and the power regulating switch 13 a...

Embodiment 2

[0048] Embodiment 2 is different from Embodiment 1 in that: the control circuit is also electrically connected to a buzzer, and the buzzer can emit a prompt sound when the battery is too low, charging is completed, and the power is adjusted ( not shown in the figure).

Abstract

The invention discloses a cell box for body heater and a control method of the cell box. The cell box comprises an outer shell, a control circuit and a charging cell which is electrically connected with the control circuit. The cell box is characterized in that the control circuit is provided with a charging connector, a discharging connector, a charging-discharging protecting chip, a voltage stabilization chip and a diode, after the charging connector is isolated through the diode, the charging connector is divided into two paths, one path charges the charging cell through the charging-discharging protecting chip, the other path carries out direct discharging through the discharging connector, and the charging connector and the discharging connector are arranged on the outer surface of the outer shell. According to the cell box, the charging connector, the discharging connector, the charging-discharging protecting chip, the voltage stabilization chip and the diode are added on the control circuit so that the cell box can carry out charging and discharging at the same time, above all, a charging socket and a discharging socket are arranged on the outer surface of the outer shell, a user can carry out inserting and using conveniently, operation is easy, and the circuit principle is simple and reasonable.

Description

technical field [0001] The invention relates to a body warmer, in particular to a battery box for the body warmer. Background technique [0002] Existing body warmers (example waist warmers), see Figure 5 As shown, it includes a waist belt 2 , a heating element 3 , a battery box 1 and a control wire 4 . The heating element 3 is arranged in the belt body 2, and the outer surface of the belt body 2 is provided with a battery box storage bag 21, and the left and right sides of the battery box storage bag 21 are provided with openings 22, and the battery box 1 is inserted into the battery box storage bag 21 through an opening 22 . Both ends of the control line 4 are respectively connected to the heating element 3 and the power supply control plug 41, and the surface of the shell 11 of the battery box 1 is provided with a socket for discharging or charging (the power supply control plug 41 can be matched with the socket). A control panel 12 is provided on the front A of the ho...
