Safe and controllable temperature control device of electric heating kettle

Abstract

The invention discloses a safe and controllable temperature control device of an electric heating kettle. The temperature control device comprises an electrical female socket and a switch control device, wherein the switch control device comprises a switch button and a lever, one end of the lever is connected with the switch button and the other end of the lever passes through the electrical female socket and extends out; the switch control device further comprises a magnetic resetting mechanism and blades, each blade is provided with an absorption tendon at the position corresponding to the magnetic resetting mechanism, and the absorption tendon is used for concentrating adsorbability and protrudes downwards to contact with the upper surface of the bottom of the electric heating kettle, the magnetic resetting mechanism drives the lever to sway up and down around an articulated shaft through up and down movements generated by mutual attracting or separation between the blade and the magnetic resetting mechanism, thereby the lever is respectively located at an switching-on position or a switching-off position of a circuit in the electrical female socket so as to control the switching-on or switching-off of power of the electric heating kettle. In the invention, air bubble generated in water after being boiled and driving force of water flow are utilized to drive the blades to rotate so as to control the lever to cut off an electrical device, the safety of an electric apparatus is improved, and the service life of the electric apparatus is prolonged.

Description

technical field [0001] The invention relates to a temperature control device for an electric kettle, in particular to a safe and controllable temperature control device for the electric kettle. Background technique [0002] The electric kettle is an indispensable appliance in daily life, and the temperature control device of the electric kettle is an important part of it. Common electric kettles in the prior art are as figure 1 , Figure 1A As shown, it includes a pot base 14, a pot body 3, a pot lid 1 and a temperature control device. The pot body 3 is provided with a handle 2. The temperature control device includes a power base 11 and a switch control device. Inside the kettle base 14 at the lower part of the kettle body 3, and electrically connected to the heating disc 5, the heating disc 5 is attached to the bottom 3a of the lower part of the electric kettle body 3, and the pot base 14 is also provided with a steam chamber for steam to enter 8. The power base 11, the...

AI Technical Summary

Problems solved by technology

[0007] (1) Because water vapor is drawn around electrical components, water vapor directly enters into contact with charged components such as heating plates, electrical contacts, terminals and other components, posing potential safety hazards

[0008] (2) Since the steam pipe in the switch control device can only be fed with steam, if water is accidentally added to the steam pipe to cause overflow, the steam cannot enter the steam chamber from the steam pipe, and the deformation of the steam sensitive sheet cannot be controlled, and the lever will always In the conduction position of the power socket, the power device is always on, causing the heating plate to continue to heat up, which may dry up the water in the electric kettle or even cause other accidents

[0009] (3) Even if the user does not add water into the steam pipe when adding water, water will often splash into the steam pipe when the water is boiling, causing the steam pipe to be blocked, resulting in the danger of the switch control device not working properly

[0010] (4) During the intermittent use of the above-mentioned electric kettle, the steam pipe in the kettle is prone to breed bacteria or mildew, which affects the health of the user and does not meet the hygienic requirements
