CN203969358U - A kind of electric Insulating slippers with energy storage function - Google Patents

Abstract

The utility model relates to an electric warm-keeping slippers with power storage function. The upper and lower soles of the slippers are provided with electric heating wires and a built-in battery. The inner side of the upper is provided with an AC power supply interface and a battery working switch. It has three working modes: AC power supply mode, AC power charging mode, and battery power supply mode. In the AC power supply mode, the heating wire, the temperature control switch, and the AC power supply form a series circuit to heat the sole. In charging mode, the built-in battery, protection resistor, and AC power supply form a series circuit to charge the built-in battery. In the battery-powered mode, the built-in battery, protective resistor, heating wire, and temperature control switch form a series circuit to heat the sole. The slippers not only have a good heat preservation effect, but also can facilitate users to move around freely indoors because of their battery power storage function.

Description

Electric warm slippers with electric storage function

technical field

The utility model relates to a winter household slippers. the

Background technique

Insufficient heating equipment in homes in southern my country often leads to low indoor temperatures, making people feel cold. Especially the feet, traditional Chinese medicine says "cold starts from the feet", keeping the feet warm is very good for health, so it is particularly important to keep your feet warm in winter. The working principle of ordinary warm slippers is to rely on the temperature of the human body to heat the body of the slippers, while the function of the slippers is to prevent the heat from dissipating too quickly. But for those with a colder constitution, this kind of slippers can't play a good role in warming feet, so electric warm slippers should be born in due course. Electric warm slippers can realize the transformation of electric energy into heat energy, and then realize the heat transfer from the outside to the feet. In addition, the shoes themselves have the function of preventing heat loss, and their warmth retention effect is far better than that of ordinary slippers. At present, most of the electric warm slippers on the market need to be powered on for heating before use, or work under the condition of continuous power on, which brings great inconvenience to indoor free walking. Warm slippers are required, which can also facilitate indoor walking. the

Contents of the invention

The purpose of the utility model is to design an electric thermal slippers with electric storage function, aiming at the defect that ordinary thermal slippers are not suitable for people with colder constitutions, and the electric thermal slippers in the market are not convenient for users to walk around at will. the

The technical solution is: an electric warm slippers with power storage function, which is composed of a controller and a shoe upper, and is characterized in that: the two ends of the controller are respectively connected with an AC power supply connector connected with an AC external interface and a plug connected with an AC power supply . The inner side of the upper is provided with an AC external interface and a battery working switch. A heating wire, a temperature control switch, a built-in battery and a protection resistor are arranged inside the upper, wherein the heating wire and the temperature control switch are connected in series, and the built-in battery and the protection resistor are connected in series to form two current branches. Under the control of the built-in switch in the controller, the two branches can be respectively connected to the external AC power supply to form a series circuit. When the branch circuit where the heating wire is connected, the heating wire generates heat to heat the slippers, and when the branch circuit where the built-in battery is connected is connected, the built-in battery is charged. If the AC power supply is cut off, the battery working switch acting between the above two branches can control the on-off between the two branches, and the battery working switch is closed. The above two branches form a series circuit, and the built-in battery supplies power for the heating wire. . the

The beneficial effect of the utility model is that the mode can be freely switched between the AC power supply mode and the battery power supply mode, which is convenient for indoor personnel to move around at will. At the same time, after the AC working mode is finished, switching the battery working mode can not only keep warm for a long time, but also achieve the purpose of saving electricity. the

Detailed ways

The utility model will be further described in conjunction with Fig. 1 and Fig. 2 . the

AC power supply mode: turn on the power, move the built-in switch 3 of the controller to the a contact, that is, press the "heating" button on the controller 2, so that the external power supply, the heating wire 12, and the temperature control switch 9 form a series circuit, and the sole for heating. When the temperature exceeds the rated temperature, the temperature control switch 9 is automatically disconnected, and the heating ends. the

AC charging mode: turn on the power, move the built-in switch 3 of the controller to the b contact, that is, press the "charge" button on the controller 2, so that the external power supply, the built-in battery 10 and the protection resistor 11 form a series circuit for charging. the

Battery-powered mode: turn off the battery work switch 1, so that the built-in battery 10, the protection resistor 11, the heating wire 12, and the temperature control switch 9 form a series circuit to heat the sole. the

After the AC power supply mode ends, the battery power supply mode is turned on again, which can achieve the effect of keeping warm for a long time and save power. the

Lay the heating wire in the manner shown in Figure 3, based on the following considerations: the main parts where the feet feel cold are the front and heel of the sole of the foot, mainly at the base of the toes, so the above parts should be considered first when designing the placement of the heating wire. At the same time, In order to achieve the best heat transfer efficiency and control area of the heating wires, according to the current arrangement of the heating wires that can be mass-produced, the heating wires for shoe soles are arranged as shown in Figure 3. the
