When working, just push the segment control switch push button on the shell panel, there are three segments of high temperature, medium temperature and low temperature respectively, and three indicator lights of different colors indicate. Select the temperature to the required level, and the circuit will work according to the set instructions. When the set temperature is reached, it will automatically keep warm, and when the set temperature is lower than the set temperature, the circuit will automatically heat up. The segment indicator light will be displayed. Its work is to adopt the delayed discharge method, and there is also a charge and discharge protection device for the battery on the circuit board.

Description

Battery heating section control hand warmer

technical field

The utility model relates to an electric heating hand warmer, in particular to a safe and reliable battery heating hand warmer which can be controlled by battery heating in sections.

Background technique

At present, there are many types of hand warmers on the market, such as electric hot water bags, fuel oil hand warmers, electric hand stoves, etc. Their biggest disadvantage is that they cannot be separated from the mains, and the fuel oil has an open flame, which is unsafe. And hurt people.

Contents of the invention

In order to overcome the above shortcomings, the utility model adopts a hand warmer controlled by battery heating in sections. It is small in size, easy to carry, safe and reliable, and can heat and warm hands at any time. The temperature can also be controlled in sections, and it can be used by people of all ages. Is an ideal hand warmer.

The technical solution adopted by the utility model to solve the technical problem is: this safe and reliable battery heating section control hand warmer has a metal shell to facilitate heat transfer. The inner layer of the casing is equipped with a heating element, a heat insulating layer is arranged under the heating element, and a rechargeable battery is placed in the middle. The working circuit board and temperature control components are installed next to it. Install control switch push buttons, indicator lights and charger sockets on the panel of the shell. When working, just push the segment control switch push button on the shell panel, there are three segments of high temperature, medium temperature and low temperature respectively, and three indicator lights of different colors indicate. Select the temperature to the required level, the circuit will work according to the set instructions, and automatically keep warm when the set temperature is reached.

When the temperature is lower than the set temperature, the circuit will automatically heat up again. The segment indicator light will be displayed. Its work is to adopt the delayed discharge method, and there is also a charge and discharge protection device for the battery on the circuit board.

The utility model has the beneficial effects of the hand warmer with battery heating segmental control: safe and reliable, easy to carry, can be used by all ages, and has the advantages of fast heating.

Description of drawings

Figure 2 is a schematic diagram of the internal structure.

In the picture, 1 is the metal shell, 2 is the indicator light, 3 is the low push button, 4 is the middle push button, 5 is the high push button, 6 is the delay and battery protection circuit board, 7 is the temperature control switch of the low temperature section , 8 is a temperature control switch in the middle temperature section, 9 is a high temperature section temperature control switch, 10 is a rechargeable battery, 11 is a heating element ceramic heating element, and 12 is a charger socket.

Detailed ways

When working, just push any one of the segment push buttons 3, 4, and 5, and the hand warmer will start to work and generate heat. When the temperature rises to the set temperature, the temperature control switch will automatically break the circuit and stop working, and start to keep warm. When the temperature is set, the circuit will automatically work and heat up. When it is turned off, as long as the segment push button is reset, it will be automatically turned off and all work will be stopped, which is very convenient to use.
