Patent Application
20230389138
The application claims priority to Chinese patent application No. 202210568758.X, filed on May 24, 2022, the entire contents of which are incorporated herein by reference.
The disclosure relates to the technical field of heating and warm-keeping equipment in particular to a power supply device for warm-keeping and heating of a container.
In the prior art, water in porcelain mugs or glasses commonly used by users for containing hot water will cool down quickly after being left for a period of time, while hot water in commonly used thermos cannot reach a temperature suitable for drinking quickly. Therefore, many users will usually put a mug on a mug warmer they had to buy, in order to keep the water temperature.
In the prior art. the mug warmer needs to be electrified during use, and a heating function cannot be realized in places where power supply is not available.
An object of the disclosure is to provide a power supply device for warm-keeping and heating of a container, to solve the problems mentioned in the BACKGROUND.
In order to achieve the above object, the disclosure provides a power supply device for warm-keeping and heating of a container, including a bottom case and a heating device. The heating device includes a battery and a heating plate. The battery is arranged in the bottom case, and the battery supplies power to the heating plate located on an upper end of the bottom case through a wire.
Preferably, an upper end of an inner cavity of the bottom case is provided with a sealing support and a scaling ring, and the sealing ring mounted on an outer wall of the sealing support is configured to seal a gap between the bottom case and the sealing support.
Preferably, the power supply device further includes a heat insulation pad. The heat insulation pad is arranged between the heating plate and the sealing support.
Preferably, a mounting support is arranged in the bottom case, and the battery is mounted and fixed in the bottom case through the mounting bracket.
Preferably, the power supply device further includes a main board arranged in the bottom case, and a power button and a plurality of indicator lights arranged on a bottom surface of the bottom case. The power button is electrically connected to the main board through a conductive ring.
Preferably, the power supply device further includes a wireless charging device for charging the battery. A magnet cooperating with the wireless charging device is arranged in the bottom case.
Compared with the prior art, the disclosure has the following beneficial elects:
By arranging the heating device and the bottom case and arranging the battery and the heating plate, heating and warm-keeping functions can be realized, so that heating and warm-keeping of the container that needs to be heated can be realized in any place without connection to a power supply, which brim great convenience.
In the figures: 1, heating device; 11, battery; 12, heating plate; 2, bottom case; 21, sealing support; 22, heat insulation pad; 23, mounting support; 24, main board; 25, power button; 26, indicator light; 27, magnet; 211, sealing ring; 3, wireless charging device.
In order to facilitate the understanding of the disclosure, the disclosure will be described more comprehensively with reference to the related drawings, in which several examples of the disclosure are shown. However, the disclosure may be realized in different forms, and is not limited to the examples described herein. On the contrary, these examples are provided to make the disclosure more thorough and comprehensive.
It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the another element or there may be an intervening element. When an element is referred to as being “connected to” another element, it may be directly connected to the another element or there may be an intervening element at the same time. As used herein, the terms “vertical”, “horizontal”, “left”, “right” and the like are only for the purpose of illustration.
Unless otherwise defined, all technical and scientific teens used herein have the same meanings as commonly understood by those skilled belonging to the technical field of the disclosure. The terms used in the specification of the disclosure are only for the purpose of describing specific examples and are not intended to limit the disclosure. The term “and/or” used herein includes any and all combinations of one or more related items listed.
The disclosure will be further described in detail below in conjunction with the accompanying drawings.

The specific operation of Example I of the disclosure is as follows:
The plurality of indicator lights 26 are used to indicate the temperature and the battery level respectively (by the aid of a wireless intelligent module, the main board 24 is remotely controlled through the Internet to set the temperature: three NTC sensors arranged on the heating plate 12 can detect the temperature of the heating plate 12 more intelligently; and when the temperature exceeds the set value, the power of the heating plate 12 is cut off through the main board 24, thereby avoiding heating of the container without water or rapid heating).
The battery 11 supplies power to the heating plate 12, so that heating and warm-keeping of the container placed on the heating plate 12 can be realized.
The battery 11 is charged magnetically, which is more convenient to use. The output of the adapter of the wireless charging device 3 is 24V 2 A, which is a safe conventional voltage. This further improves the safety and stability of the product, and makes the wireless charging device easier to purchase and replace.
Double heating elements are used in the heating plate 12. Double circuits are intelligently energized to generate heat so as to form a vortex within the range of a heating module, so that the container can be heated uniformly.
The disclosure is described exemplarily by means of above-mentioned description in conjunction with the accompanying drawings. Apparently, the specific implementations of the disclosure are not limited by the above-mentioned manner. Any immaterial improvement carried out by adopting the method concepts and technical solution of the disclosure or the direct application of the concepts and technical solution of the disclosure to other occasions without any improvement shall fall within the scope of protection of the disclosure.
