Description

Heating structure of hot water bag

technical field

The utility model relates to a heating structure of a hot water bag, in particular to a heating structure that can quickly and evenly heat the heat-conducting material in the hot water bag, and has multiple safety devices to ensure user safety and product life.

Background technique

Referring to Fig. 1, the heatable hot water bag a generally used usually utilizes a temperature-resistant and leak-proof bag body a1 to install an electric heating device b inside the appropriate position, and the bag body a is equipped with heat-conducting and electrically-conducting Liquid substance c, the electric heating device b utilizes the front-end heating element b1 to conduct electricity in the above-mentioned liquid substance c and then starts to generate heat to achieve the purpose of heating, but the heating element b1 is directly connected to the electric heating device b, mostly in the form of an electric heating rod, The problem of excessive concentration of heating points has occurred. When the hot water bag a is heated, the temperature of the part close to the heating element b1 will be particularly high. Therefore, it cannot be used for a long time while heating, and the electric heating device b is connected to the power supply. The part connected to b2 will often cause separation or uneven contact of the contact points due to the continuous movement of the hot water bottle a, which may not only cause damage to the hot water bottle a, but also may cause the life safety of the user to be threatened. It is necessary to improve.

Utility model content

The main purpose of the utility model is to provide a heating structure that can quickly and evenly heat the hot water bag, and has multiple safety devices to ensure the safety of users and the life of the product.

In order to achieve the above purpose, the heating structure of the hot water bag of the present invention includes a casing, an electronic device, two electric heaters and a power connection wire, etc., the electronic device is installed in the casing, and the casing is installed in the bag On the body, the two electric heaters are respectively fixed to appropriate positions on both sides of the inner surface of the hot water bag with the fixing frame, and then the electric heater is connected to the electronic device with a waterproof circuit. The electronic device is equipped with a temperature controller and is connected to the power supply There are three conductive terminals and a protruding post in the jack. When in use, connect the power connection line with the electronic device. At this time, the protruding post can be inserted into the induction switch hole of the power connection line correspondingly, so that the induction A warning light inside the switch illuminates and power is ready.

When used according to the above structure, since the electric heating sheet is used for heating, the heating speed can be increased with the increase of the area of the electric heating sheet, and the electric heating sheet is installed at an appropriate position on both sides of the inner surface of the bag; and In the hot water bags commonly used in the past, the heating source is installed at an appropriate position on either side of the hot water bag. When heat is transferred, the distance from the heating source to each corner of the hot water bag is not the same, which may cause uneven heating or too slow heating. Therefore, the heating speed and heating method of the utility model are far faster and more uniform than the electric heating rod type used in the conventional structure. In addition, the hot water bag is a frequently moving item, so the conventional hot water bag and the power connection line The connection part of the utility model will often fall off without the user's knowledge, causing safety problems in use, and the electric heating rod will burn out and affect the service life of the product. However, the power connection line of the utility model is provided with an induction switch. As a safety device for confirming that the power connection line is connected with the hot water bag, the above-mentioned problems can be avoided.
