Automatic heating PTC high polymer cup

Abstract

The invention discloses an automatic heating PTC high polymer cup. The automatic heating PTC high polymer cup comprises a cup body and a cup lid, wherein a heating cavity is formed in the cup body, and a PTC heating piece is arranged in the heating cavity; an outer shell of the cup body is a heat-resistant cup shell, and an inner shell of the cup body is a heat conducting cup shell; the heating cavity is formed between the heat-resistant cup shell and the heat conducting cup shell; a conducting component is arranged at a cup opening of the cup body; a power supply device is arranged in the cup lid and comprises a wire and a battery mounting box, the cup lid is convex, and the left step and the right step of the convex shape are connected with the wire; a suction device is arranged at the bottom of the cup body; a flexible support is arranged between the suction device and the cup body. The cup has the beneficial effects that a PTC thermosensitive ceramic element is adopted as a heating body, the cup is convenient to carry and use, free of open fire and high in heat conversion rate, has a constant temperature heating capability, and is more convenient and environment-friendly when used by a user, and the influence of power voltage is extremely small; in addition, the suction device is arranged at the bottom of the cup body, so that the cup body can be effectively prevented from toppling and falling.

Description

technical field [0001] The invention belongs to PTC polymer heating products, and in particular relates to a convenient automatic heating water cup, which can effectively prevent the water cup from tipping over at the same time. Background technique [0002] With the development of science and technology, the improvement of people's living standards, and the convenience and health of life, the current heating water cups are mainly heated by resistance heating wires, mechanical temperature controllers, and microwaves. They all exist. Some disadvantages: using resistance heating wire for heating, power and current will increase with the increase of voltage, the working current is unstable, and the current limiting device of some vehicles restricts its use, mechanical temperature control increases the complexity of the product structure , while increasing the cost, its use effect is not ideal; and the cost of the microwave method is too high, which limits the popularization and...
