Electric pressure cooker cover opening and closing signal feedback device

Abstract

The invention discloses an electric pressure cooker cover opening and closing signal feedback device. When a cover body of the electric pressure cooker is in a closed position, a conductive ball is in a switched-on position, and a first conductor and a second conductor are switched on by the conductive ball; when the cover body of the electric pressure cooker is in an opened position, the conductive ball is in a switched-off position, the first conductor and the second conductor are switched off. According to the electric pressure cooker cover opening and closing signal feedback device, an electronic switch in the prior art is replaced by a mechanical switch; the structure is simple; the electric pressure cooker cover opening and closing signal feedback does not need to rely on the switching on and off of electric, magnetic and optical control switches; the position of the conductive ball is changed by means of the self gravity of the conductive ball by only changing the position of the cover body; the switching on or off of the first conductor and the second conductor is used as a signal for controlling the heating of the electric pressure cooker; when the position of the cover body is changed, the opening and closing of the cover body are directly related to the heating; the reliability is higher; the control switch is unlikely to damage even when the control switch is used in the high-temperature and high-humidity environment for a long time; the use safety can be ensured; the manufacture and maintenance costs are low.

Description

technical field [0001] The application belongs to the technical field of safety accessories for electric pressure cookers, and in particular relates to a signal feedback device for opening and closing lids of electric pressure cookers. Background technique [0002] With the development of kitchen appliances, electric pressure cookers are favored by more and more consumers, and their household penetration rate is getting higher and higher. Electric pressure cookers are also constantly being updated, from the initial single function to multi-functional development. [0003] The electric pressure cooker on the market basically realizes the cooking function now, but when using the cooking function of the electric pressure cooker, the cover must be opened for operation, otherwise there will be a risk of danger. Therefore, how to ensure that the cover of the electric pressure cooker is in an open state when the electric pressure cooker uses the cooking function, or how to stop hea...

AI Technical Summary

Problems solved by technology

[0004] In the prior art electric pressure cooker with cooking function, most of the lid closing mechanisms are controlled by magnetic switches. Since the lid of the electric pressure cooker is often opened and closed, and because the electric pressure cooker is often used in an environment with high temperature and high humidity, As a result, the magnetic control switch is easy to damage and fail, and the safety and reliability are low. In the case of damage and failure of the magnetic control switch, there is no way to ensure the opening operation of the electric pressure cooker. It is very dangerous to use the cooking function of the electric pressure cooker, and The manufacturing cost of the magnetic control switch is high, and the cost of repair and replacement after damage is also high, which causes inconvenience to consumers
