A power control unit (100) is provided with: a temperature detecting unit (101), which detects the temperature of a battery unit (4); and an integration counter (102), which integrates a value allocated to the temperature of the battery unit (4), said temperature having been detected by the temperature detecting unit (101). The power control unit (100) reduces power to be supplied to an LCD display unit when an integrated value integrated by means of the integration counter (102) exceeds a predetermined value.

An electric power control section includes: a temperature detecting section for detecting temperatures of a battery; and an accumulation counter for accumulating numerical values assigned to the respective temperatures of the battery which have been detected by the temperature detecting section. The electric power control section reduces electric power supply to an LCD display section when an accumulated value obtained by the accumulation counter exceeds a preset value.

This application relates to the field of electric blanket production, specifically a control circuit for a safe mite removal electric blanket that satisfies electromagnetic compatibility requirements, wherein the power circuit is connected to a single-chip microcomputer control circuit and a trigger circuit; the single-chip microcomputer control circuit is connected to a trigger circuit and a power control circuit connected; the display circuit is connected in parallel with the switch; the power supply circuit is connected to the heating element through the main thyristor V1 and the slave thyristor V2 in the power control circuit, and the protection circuit is connected to the power supply circuit at the same time. In this application, while applying the parallel connection of varistor and capacitor to absorb pulse interference, a self-recovery fuse is connected in series in the power supply circuit to block the large current formed by pulse interference lower than the limit value of varistor; The half-wave gate circuit realizes the zero-crossing trigger, which avoids interference to the grid environment; the combination of human body contact with safe temperature and dehumidification and drying realizes mite removal, which avoids low-temperature burns or heat stroke injuries that may be caused by high-temperature mite removal.

The invention discloses a fracture splint with heat preservation function, including a left splint, a right splint and a fastening strap, the left splint and the right splint are identical in structure and symmetrical to each other, the left splint has a three-layer structure, from the inside out, A heat layer and an insulation layer are arranged on the end face of the heat storage layer facing the human skin at parallel intervals. A plurality of heat insulating strips are arranged in the heat storage layer. A heating element is arranged in the heat storage layer. The heating element performsswitch control and temperature control through a knob arranged on the end face of the left splint. The insulation layer avoids heat loss of the heat storage layer and the heat storage layer. At present, when that fracture splint is used for treating the patient, the splint is installed at the patient's wound depending on the site of the fracture; in common medical practice, is performed by removing the fracture splint and applying heat to the patient's wound to promote blood circulation, which is likely to cause damage, whereas in the present application, the left splint and the right splint are arcuate, and the arcuate junction is used to fit with the arm.

The invention discloses a preparation method of a self-heating fabric. The technological process is: weaving→pretreatment→soft finishing→drying→heat setting→self-heating wax treatment and health care finishing→heating dripping→finished product. The self-heating wax treatment health care finishing process is: mixing tourmaline stone powder, far-infrared ceramic powder, beeswax and paraffin in a mass ratio of 10-30:5-20:10-30:10-30, heating to 70-90 ℃, and high-speed stirring to mix evenly to prepare a self-heating wax treatment mixture, then drop it on the surface of the heat-set fabric, cool and solidify at room temperature, and form self-heating wax treatment health care particles; the heating dripping process is: polyurethane elastic Crystal glue A and B are mixed evenly, vacuumized, and then dropped on the surface of self-heating wax therapy health care particles, and dried and solidified. The invention effectively prevents skin from being scalded at low temperature, eliminates the influence of weather changes on fabric properties, and at the same time endows fabrics with wax therapy and health care effects, and improves the washability of functional fabrics.
