[0044] The present invention achieves excellent thermal insulation by placing the heating assembly 5 on the inner liner 3 to heat the inner liner 3 and keep the water warm. The heating assembly 5 is separated from the outer shell 4 to prevent heat from being conducted away from the outer shell. Furthermore, by configuring the heating assembly 5 as a low-voltage heating element heated by a battery 16 and / or a high-voltage heating element heated by lighting electricity, the portable thermos cup has both thermal insulation and water heating functions, making it more suitable for user needs. Specifically, the following technical effects are achieved.

[0045] 1. The inner liner 3 and the outer shell 4 of the utility model are sealed and a vacuum space is formed on the side wall and bottom of the inner liner 3 to reduce the heat conduction of the water to the outside, which can increase the heat preservation time of the water in the cup;

[0046] 2. The utility model can be equipped with three types of base components, one with low voltage and only battery, another with high voltage and only external lighting power, and the other with both low voltage and high voltage, which can be connected to batteries and external lighting and heating to meet various needs;

[0047] 3. The inner tank 3 is provided with a temperature sensor to activate or deactivate the heating assembly 5. The temperature sensor is electrically connected to the base PCB 20 via the cup connector 12 and the base connector 15. When the battery power is sufficient, the water in the cup can be kept at a constant temperature.

[0048] 4. The water cup assembly 1 and the base assembly 2 are arranged to be detachably connected, and the base assembly 2 can be replaced;

[0049] 5. The heating assembly 5 includes a low-voltage heating element heated by a battery and / or a high-voltage heating element heated by lighting electricity. The low-voltage heating element and / or the high-voltage heating element are directly or indirectly electrically connected to the base assembly 2.

[0050] The present invention is a liquid heating constant temperature cup with a built-in double-layer vacuum (including bottom vacuum) heating element. The product is an upgrade and structural innovation aimed at the technical barriers of constant temperature time and heat loss of portable heating constant temperature water cups currently on the market. The existing products on the market are generally single-layer stainless steel cups, which are not vacuumed or double-layer stainless steel cups with vacuumed side walls. A heating component 5 is placed at the bottom to be powered by a battery for heating and constant temperature. The bottom is always single-layer, which will lead to rapid heat loss. In order to ensure that the liquid is at a consistent constant temperature in the cup, the energy consumption will be very high under certain temperature conditions, resulting in the problem that the battery 16 consumes power too quickly and the constant temperature time becomes shorter. Now, in combination with ordinary vacuum stainless steel portable thermos cups on the market, the heating component 5 and the temperature sensor module are integrated into the vacuum layer of the portable thermos cup, so that the entire cup body is vacuumed to reduce the heat loss rate, achieving a constant temperature or greatly reducing energy consumption when heating the liquid inside the cup body.

[0051] The cup body consists of two parts: an inner liner 3 and an outer shell 4. First, the heating component 5 and the temperature sensor are installed on the surface of the inner liner 3. Then, the outer shell 4 is welded to the inner liner 3 and connected to the heating component 5 and the temperature sensor with a wire 7 at the bottom of the outer shell, which is then led out to the outside of the outer shell 4 for connection. The wire 7 and the wire hole 6 of the outer shell 4 are sealed. At this time, the cup body with the built-in heating component 5 and temperature sensor forms a sandwich stainless steel cup body. The cup body is vacuum-sealed to form a vacuum layer in the sandwich of the cup body, which ensures that the heat flow of the heated liquid in the inner liner 3 of the cup body is transferred and acts as a barrier.

[0052] This effect is achieved by heating the liquid in the original portable thermos cup through the heating element after the heat of the liquid is lost, keeping the liquid temperature constant at the temperature set by the user. In the protective product, the heating element is built into the vacuum interlayer of the cup body.

[0053] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
