Description

  The present invention relates to an improvement in the heating structure of a hot water bottle, and in particular, heats the heat conductive material in the hot water bottle quickly and evenly and is equipped with multiple safety devices to ensure the safety of the user and extend the life of the product. The present invention relates to a hot water bottle heating device.

  As shown in FIG. 1, a commonly used heatable hot water bottle a uses a bag body a1 that is usually heat-resistant and leak-proof, and an electric heating device b is installed inside the appropriate position. In addition, a liquid material c capable of conducting heat and having conductivity is placed in the bag a1, and the electric heating device b uses the heat generating component b1 at the front end to generate heat after conducting in the liquid material c. To reach the purpose of heating. However, since the heat generating component b1 is directly connected to the electric heating device b and many of them adopt the electric heating rod type, there is a problem that the heating points are concentrated too much, and when the hot water bottle a is heated, Since the temperature of the part near the installation position of the heat generating component b1 becomes particularly high, it cannot be used for a long time, and the hot water bottle a is also connected to the part where the electric heating device b and the power cord b2 are connected. Continuous movement can easily cause dropouts or poor contact at the power connection point, which not only leads to damage to the hot water bottle a, but can also threaten the safety of the user's life. It has been.

  The present invention has been made in view of the above-mentioned drawbacks of the conventional structure, and has been devised based on many years of experience in the business of the creator, and devised an improved heating structure for a hot water bottle.

  The main purpose of the present invention is to provide a heating structure that can quickly and evenly heat a hot water bottle, and to ensure the safety of the user and to extend the life of the product with multiple safety devices. It is to provide a heating device.

  In order to achieve the above object, a hot water bottle heating device of the present invention comprises a housing, an electronic device, two electric heating pieces, and a power cord. The electronic device is installed in the housing, and the hot water bottle is connected to the hot water bottle. It is installed on the bag body, and two electric heating pieces are fixed to the appropriate positions on the two sides inside the hot water bottle with a fixed frame, and the electric heating piece and the electronic device are connected with a waterproof circuit, and the temperature is controlled in the electronic device. An insertion hole connected to the power supply cord and the power cord, and three power connection terminals and a convex column body are installed in the insertion hole, and the power cord and the electronic device are connected to each other when in use. The body is inserted into the safety switch hole of the power cord, and a warning lamp inside the safety switch is caused to emit light, thereby being energized.

  Due to the above-described structure, heating is performed in a manner using an electric heating piece when used, so that the heating rate is accelerated as the area of the electric heating piece is increased, and the present invention further positions the electric heating piece at two proper positions inside the hot water bottle. However, the conventional hot water bottle used in general is only installed at an appropriate position on the inner surface of the hot water bag bag. The distances from the hot water bottle to the corners of the hot water bottle are different, and problems such as uneven heating and excessive time for heating easily occur. For this reason, the present invention makes the heating rate and heating method faster and more uniform than the conventional electric heating rod type, and the hot water bottle is an article that is always moved. Therefore, in the conventional hot water bottle, the hot water bottle and the power cord The connection point often comes off without the user's knowledge, causing a safety problem in use, and the heating rod may be burned out and affect the service life of the product. Is provided with a safety switch to ensure that the power cord and the hot water bottle are securely connected to each other, so that the above-mentioned problems can be avoided.

  Hereinafter, the structure, apparatus, and features of the present invention will be described in detail with reference to the best embodiments and drawings.

  As shown in FIGS. 2, 3, and 4, the hot water bottle heating device of the present invention includes a housing 10, an electronic device 20, two electric heating pieces 30, and a power cord 40, of which the housing 10 Is composed of an outer casing 11 and an inner casing 12, and is installed in a manner sandwiched between appropriate positions on the surface of the hot water bottle 2. A water injection hole 11a and an insertion hole 11b corresponding to the power cord 40 are provided on the outer casing 11, The convex column body 11b1 is installed in the insertion hole 11b, the inner shell body 12 and the outer casing body 11 are assembled in a box shape, and the electronic device 20 is installed in the outer casing body 11 and the inner shell body 12. The electronic device 20 includes a temperature controller 21 and three power connection terminals 22 drilled in the insertion hole 11b of the outer casing 11, and further, two electric heating pieces 30 are fixed to a fixed frame 31 (see FIGS. 5A and 5B, The fixing frame 31 is fixed to two appropriate positions on the inner surface of the hot water bottle 2 using a cross shape or a well shape, and the electric heating piece 30 and the electronic device 20 are connected by a waterproof circuit. The power cord 40 is inserted into the insertion hole 11b of the outer casing 11, and the power cord 40 includes three conductive portions 41 and a safety switch 42. The conductive portion 41 is a power connection terminal of the electronic device 20. When the power cord 40 is inserted into the insertion hole 11b and used, the safety switch 42 is pressed by the convex column 11b1 installed in the insertion hole 11b, and the safety switch 42 is driven. When connected and the warning lamp 42a is turned on, power is normally supplied and the purpose of use can be achieved.

  As described above, the hot water bottle heating device of the present invention has a heating structure including a casing, an electronic device, two electric heating pieces, and a power cord, and can not only quickly and evenly heat the hot water bottle, but also has multiple safety features. Since the device has the effect of ensuring the safety of the user and extending the life of the product, and has both utility and inventive step, the application for utility model registration is filed here based on the provisions of the Patent Law.
