Embodiment 1

[0029] see figure 1 , an electric heating appliance for heating liquids, comprising a heating tube 1, a heating body 2 and a power cord 3, the heating body 2 is packaged in a closed lumen 4 of the heating tube 1, and the power cord 3 has opposite first ends and second Among them, the first end is used to connect with the external power supply, and the second end seals through the tube wall of the heating tube 1 and is electrically connected to the heating body 2. When it is necessary to heat liquids such as water, it is only necessary to connect the heating tube 1 Put it in the liquid, connect the power line 3 to the power supply, make the heating element 2 energized and generate heat, and conduct the heat to the liquid through the heating tube 1, so that the liquid can be heated. In addition, an exhaust hole 5 is provided inside the power cord 3, and when the heating tube 1 is placed in the liquid to be heated, the exhaust hole 5 communicates the sealed lumen 4 with the outsi...

Embodiment 2

[0040] see Figure 8 , different from Embodiment 1, the first end of the power line 3 is connected to the control box 15 arranged outside the gas to be heated, the control box 15 is provided with a power plug 6, and the control box 15 is provided with a control panel, and the power plug 6 and the power line 3 are electrically connected to the control panel, and the exhaust hole 5 passes through the power line 3 and communicates with the control box 15, and the control box 15 is provided with a second exhaust hole 16. Such a design makes the internal expansion gas pass through the power cord 3 with the exhaust hole 5, enter the inner cavity of the control box 15, and then be discharged by the second exhaust hole 16 of the control box 15, compared with the direct discharge through the power plug 6. Gas, which can effectively avoid the impact of the discharged high-temperature gas on the power plug 6 or socket 8.

Abstract

The invention discloses an electric heating appliance for liquid heating, and aims to effectively solve the problem of heating tube explosion caused by gas expansion. Therefore, the electric heating appliance provided by the embodiment of the invention comprises a heating tube, a heating body and a power line, the heating body is arranged in a closed tube cavity of the heating tube, and the power line is provided with a first end and a second end which are opposite to each other; the first end is used for being connected with an external power source, the second end penetrates through the pipe wall of the heating pipe in a sealed mode and is electrically connected with the heating body, an exhaust hole channel is formed in the power line, and when the heating pipe is placed in liquid to be heated, the closed pipe cavity is communicated with the external atmosphere through the exhaust hole channel.

Description

technical field [0001] The invention belongs to the technical field of heating appliances, in particular to an electric heating appliance for heating liquid. Background technique [0002] Electric heaters suitable for heating liquids, especially aquarium heaters, are currently on the market. Since the heater works in the liquid, the heating tube must be sealed and waterproof, and when the heating tube is energized and heated, the air in the tube will be heated and expand, resulting in an increase in the air pressure in the sealed tube, especially when the liquid evaporates or other reasons cause the container to lack water. When the device is dry-fired, the internal pressure of the heating tube is higher, which is more likely to cause the heating tube to explode (explode the tube). Some heating tubes adopt a pre-evacuation method to form a negative pressure in the closed heating tube, so that the residual gas will not heat up and expand to cause a high-pressure explosion. ...
