An overflow-proof heater

Abstract

The invention provides an overflow preventing type heater. The overflow preventing type heater comprises a bottle stopper body, a transition pipe, a heating pipe, an outgoing wire, a connecting wire, a plug, a pump, a water pumping pipe, a first water outlet pipe, a buffering box, a second water outlet pipe, a three-way electromagnetic valve and a controller, wherein the heating pipe adopts a cylindrical structure and comprises an inner cylinder, an outer cylinder and an electric heating wire enclosed between the inner cylinder and the outer cylinder; a cavity is arranged in the bottle stopper body, and the transition pipe and the heating pipe are positioned below the bottle stopper body; the pump is arranged in the cavity, the first end of the water pumping pipe is connected with the pump, the second end of the water pumping pipe penetrates through the bottle stopper body and extends into the inner cylinder, the first end of the first water outlet pipe is connected with the pump, and the second end of the first water outlet pipe penetrates through the bottle stopper body and is communicated with the buffering box arranged on the side surface of the bottle stopper body; the three-way electromagnetic valve is mounted on the first water outlet pipe, the first end of the second water outlet pipe is connected with the three-way electromagnetic valve, and the second end of the second water outlet pipe penetrates through the bottle stopper body and is positioned below the bottle stopper body; and a liquid level sensor is arranged on the water pumping pipe. The overflow preventing type heater not only can prevent boiled water from overflowing, but also can improve the heating efficiency.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to an overflow-proof heater. Background technique [0002] There are many types of heaters currently on the market. When using a heater to heat water in a thermos bottle, it is generally necessary to insert the heater into the thermos bottle and then plug in the power supply for heating. Overflow at the mouth, usually, in order to prevent overflow, the water in the thermos bottle can not be filled, but in this case, because the space in the thermos bottle cannot be seen, usually the water will be filled too much or too little; During the heating process, the temperature distribution of the hot water in the thermos bottle is often uneven, resulting in low heating efficiency. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an anti-overflow heater. [0004] An anti-overflow heater proposed by t...

[0002] There are many types of heaters currently on the market. When using a heater to heat water in a thermos bottle, it is generally necessary to insert the heater into the thermos bottle and then plug in the power supply for heating. Overflow at the mouth, under normal circumstances, in order to prevent overflow, the water in the thermos bottle can not be filled, but in this case, because the space in the thermos bottle cannot be seen, usually the water will be filled too much or too little; During the heating process, the temperature distribution of hot water in the thermos is often uneven, resulting in low heating efficiency
