Description

An electric heating insulation cup

technical field

The utility model relates to a water cup, specifically a cup that can be heated and kept warm.

Background technique

The thermos cup is generally a water container made of ceramic or stainless steel with a vacuum layer. It usually has a double-layer shell, and a vacuum insulation interlayer is formed in the middle of the double-layer shell to keep warm; at the same time, there is a lid on the top of the thermos cup. , to tightly seal the thermos cup, so that the cooperation of the vacuum insulation interlayer and the cup cover can delay the heat dissipation of the water and other liquids contained inside, so as to achieve the purpose of heat preservation. the

However, no matter how good the thermal insulation effect of this thermos cup is, after all, the temperature will decrease with the decrease of the temperature, which can only delay the cooling time of the water in the thermos cup, and the common sense that people often use the thermos cup is outdoor workplaces. , often fail to achieve the required long-term heat preservation effect, and it is inconvenient to use.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned shortcomings, and provide an electric heating thermos cup, which has the function of heating at any time, and can meet the needs of outdoor heat preservation.

Another purpose of this utility model is to provide an electric heating thermos cup, which is easy to carry, easy to manufacture and low in cost.

In order to achieve the above object, the utility model is achieved through the following technical solutions.

An electric heating thermos cup, which includes a cup cover and a cup body, the cup body has a double-layer structure, and the middle of the double-layer structure is a heat-insulating interlayer, so as to properly insulate heat and avoid rapid loss of heat; its characteristics There is an electric heating film at the bottom of the cup body, the electric heating film is connected with electrodes, and the electrodes are connected to a power supply through wires. Thus, the electric heating film can generate heat on the bottom side of the cup body where it is located, and the heat is generated from the bottom of the cup body in a balanced manner to heat the water or liquid in the cup body, thereby achieving the effect of long-term heat preservation.

The electric heating film is attached to the bottom of the inner layer of the double-layer structure of the cup body, and only heats the inner cup body to avoid scalding others.

The electric heating film is any one of geometric shapes such as circle, ellipse, square, triangle, trapezoid, polygon, and rhombus.

The electric heating film is connected to a temperature control element through an electrode, and the temperature control element is connected to a power supply through a wire, and the heating temperature can be controlled through the temperature control element.

The cup body is made of glass material, and the electric heating film, which is smaller than the bottom of the cup body, is coated on the bottom of the cup body.

The electric heating film can be two or more electric heating films, and the two or more electric heating films are all arranged at the bottom of the cup body, wherein each electric heating film leads out electrodes independently, and the electric heating film is independently Work. This structural form facilitates the control of the heating area while effectively improving the heating efficiency.

The lower part of the cup body is provided with a base, and the power supply, temperature control elements and wires are all arranged in the base to avoid damage from external forces and ensure smooth heating.

Because the utility model adopts the above-mentioned structure, the electric heating thermos cup has the function of heating at any time, can meet the requirement of outdoor heat preservation, and can provide people with water or drinks at a suitable temperature at any time.

Moreover, the utility model has a simple structure, is easy to realize, and is also convenient to carry when used, and can be suitable for use in various outdoor places.

Description of drawings

Fig. 1 is the structural representation that the utility model realizes.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods

Shown in Fig. 1, it is the structural sectional view that the utility model implements. As shown in the figure, the realization of the utility model mainly includes a cup cover 1, a cup body (the cup body also includes an outer layer 2, a heat insulating interlayer 9 and an inner layer 10), and a base 7. Wherein, the cup lid 1 and the cup body are existing structural forms, and will not be repeated here.

The core of the utility model is that the bottom of the cup body, especially the bottom of the inner layer 10, is coated with a layer of electric heating film 3, and the two sides of the electric heating film 3 are respectively provided with electrodes 4 (the electrodes 4 can be fixed by screws On the electric heating film 3), the electrode 4 is connected to the temperature control element 5, and the temperature control element 5 is connected to the power socket 6 through the wire 7. The power socket 6 can be connected to the existing AC power supply or to a DC power supply. Power supply, such as on the battery, that is to say, can directly heat the electric thermos cup through the battery, thereby being convenient for people to use.

Because the cup body made of stainless steel usually produces a fishy smell, the cup body is usually made of glass material, and the electric heating film 3, which is smaller than the bottom of the inner layer 10, is coated on the bottom of the inner layer 10. And the thickness of the electric heating film 3 is controlled at 0.05-0.1mm, and can be made into any geometric shape such as circle, ellipse, square, triangle, trapezoid, polygon, and rhombus. In the embodiment shown in FIG. 1 , the electric heating film 3 is circular and is directly coated on the bottom surface of the inner layer 10 .

The lower part of the cup body is provided with a base 7 (the base 7 is usually fixed on the outer layer 2), and the power socket 6, the temperature control element 5 and the wire 8 are all arranged in the base 7, which can avoid the damage of external force and ensure the smooth progress of heating .

In this way, the utility model can use the external power supply to heat water or beverages at any time, for example, connect the power socket 6 to the power socket of the car for heating, so that the water or beverages in the thermos cup can be heated at any time. The temperature of the water or the drink in the thermos cup can be kept for a long time, which is convenient for people to use in outdoor activities, especially in the present when the traffic is developed, it can be used in conjunction with automobiles.

In a word, the above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model.
