Abstract
The utility model discloses an electric heater, which comprises a heating wire (1), a top cover (2), a conductor (3), a plug (4), etc. The U-shaped heating wire (1) is fixedly connected with the part under the top cover (2), and externally connected with the conductor (3). An enclosed control cavity (5) is arranged in the top cover (2). The upper end plane of the control cavity (5) is provided with a clapper (6). A contact switch (7) is connected with the part above the clapper (6). The contact switch (7) is connected between the heating wire (1) and the conductor (3). The utility model heats the water to a specific temperature, the control cavity is expanded and the clapper is uplifted, the contact switch is activated, the circuit is disconnected and the operation is stopped, in this way, the electric heater not only protects the thermal insulation bottle but also saves the electric energy.
Description
Affiliated technical field
The utility model belongs to a kind of device that adds hot water, is to relate to a kind of electric heater particularly.
Background technology
In the prior art, be used for the device (being commonly called as immersion heater) that vacuum flask adds hot water, its structure is made up of " U " type heating wire, top cover and lead, has air leakage hole on the top cover.After water was boiled, hot vapour was run out of and can be given the alarm by excessive steam vent, the prompting powered-down.This electric heater is very universal, and it is comparatively convenient to use.But there is tangible deficiency: its user will keep the marquis near electric heater all the time, treats that it gives the alarm in time to turn off power supply; When the user leaves because of urgent thing or during failure alarm, it can produce huge hidden danger.The lighter burns out vacuum flask, and electric heater is scrapped, and weight person can cause fire or cause electric leakage dangerous, bring great threat for people's life.
Summary of the invention
The purpose of the utility model is to provide a kind of improved electric heater, and it has overcome the above-mentioned deficiency of prior art, and water can be cut away power supply, safety easy to use after boiled automatically.
For reaching above-mentioned purpose, the technical scheme that the utility model is taked is: the utility model includes heating wire, top cover, lead, plug etc., " U " type heating wire is fixedly linked in the top cover below, its external wire, it is characterized in that: be provided with the control chamber of sealing in top cover, the upper surface of control chamber is clappers, and the clappers top is connected with contact switch, contact switch is connected between heating wire and the lead, the control electric wire circuit.
The utility model is taked technique scheme, has following beneficial effect: the utility model is applicable to and heats cold water in vacuum flask.When water was heated to specified temp, air expansion in the control chamber made the clappers startup contact switch that raises up, open circuit, and heating wire quits work.Protect vacuum flask and heater, saved electric energy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done and to be described in further detail:
Fig. 1 is the utility model structure diagram.
Embodiment
As seen from Figure 1: the utility model includes heating wire 1, top cover 2, lead 3, plug 4, control chamber 5, clappers 6, contact switch 7, is connected with contact switch 7 between heating wire 1 and the lead 3, and clappers 6 connect with contact switch 7.In order to show working condition, on top cover 2, can be provided with indicator light 8.
