Description

A thermos cup bag

technical field

The utility model relates to a thermos cup bag.

Background technique

The thermos cup, developed from the thermos bottle, has the same insulation principle as the thermos bottle, but people make the bottle into a cup for convenience. There are three ways of heat transmission: radiation, convection and transfer. The silver liner in the thermos cup can reflect the radiation of hot water, the vacuum of the liner and the cup body can block the transfer of heat, and the bottle that is not easy to transfer heat can prevent heat convection.

Hand warmers, as the name suggests, can warm people's hands or other parts. The hand warmer uses the liquid in the hand warmer to transfer heat. Generally, it is widely used by people in winter.

The function of the hand warmer on the market is single, and there are many disadvantages, such as: short heating time, non-continuous heating, and long charging time. Some water cups have poor thermal insulation performance. In winter, people will use water cups to keep warm, and the water will be poured out when it becomes cold, which increases the waste of water sources. If the combination of the two can greatly reduce waste, the utilization rate of resources will be higher.

Contents of the invention

In view of the above situation, in order to reduce the waste of resources and facilitate people's life, the purpose of this utility model is to provide a thermos cup bag, which can effectively solve the problems that the hand warmer bag has a single function, is inconvenient to use, and the water cup has poor thermal insulation performance and is easy to waste resources.

The technical scheme solved by the utility model is to include a cup bag, the bottom of the cup bag has a base, a control circuit board, a temperature sensor and a lithium battery are arranged in the base, the relay on the control circuit board is connected in series with the lithium battery, one end of the heating wire and the control The relay on the circuit board is connected, and the other end is wound inside the side wall of the cup bag. There is a power switch and a charging interface on the side wall of the base. Both the power switch and the charging interface are connected to the lithium battery, and the temperature sensor and the sensor input on the control circuit board The ports are connected to form a thermos bag.

The utility model has the advantages of simple structure, convenient use, low cost and good effect, and integrates hand warming and heat preservation.

Description of drawings

Fig. 1 is a perspective view of the structure of the utility model.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.

Provided by Fig. 1, including the cup bag, the bottom of the cup bag 3 has a base 8, a control circuit board 6, a temperature sensor 5 and a lithium battery 10 are arranged in the base, the relay on the control circuit board is connected in series with the lithium battery, and the heating wire 4 One end is connected to the relay on the control circuit board, and the other end is wound on the side wall of the cup bag. There is a power switch 1 and a charging interface 2 on the side wall of the base. Both the power switch and the charging interface are connected to the lithium battery, the temperature sensor and the control circuit. The sensor input ports on the board are connected to form a thermos bag.

Described control circuit board 6 is the miniature thermostat that is made of temperature adjustment switch 7, digital display 9 and control circuit, as the miniature thermostat that model is WX-101W;

The cup bag 3 is a cylindrical structure with a cavity inside, the side wall of the cup bag is a composite structure composed of an inner layer and an outer layer connected together, and a heating wire is wound between the inner layer and the outer layer;

A cup filled with water is placed in the cavity of the cup bag 3;

The temperature sensor 5 is placed on the inner top surface of the base.

When using, first adjust the temperature adjustment switch on the control circuit board, set the temperature in a suitable range according to needs, turn on the power switch, and put a cup bag on the cup. If there is hot water in the cup, the cup bag can detect the cup When the temperature reaches the set minimum temperature, the heating wire in the cup bag starts to generate heat under the control of the control circuit board. When it reaches the set temperature, it stops heating, and then reaches the temperature to maintain the water in the cup. , and at the same time, it can be used for warming hands because it maintains a certain temperature. The utility model is easy to process, simple in structure, low in cost, and has good heat preservation effect. Hot water prevents the problem that the water is easy to cool after being left for a long time, greatly reduces the waste of resources, and has good economic and social effects.
