Abstract: A locking mechanism and a door opening control method are provided for household appliances. The locking mechanism is provided on a front door panel of a door of a cooking machine and used for controlling the opening and closing of the door and includes: a lever which is mounted on the back surface of the front door panel and at least a portion of which protrudes from an opening provided on the front door panel to the front surface of the front door panel; an electromagnet which is mounted on the back surface of the front door panel and may be in a locked or unlocked state with respect to the lever. The locking of the door of the cooking machine may be realized through the cooperation between the electromagnet and the lever. Real-time control of the door may be realized to better ensure safety of the user.

Abstract: A garden tool includes a base, a motor arranged on the base, a cutting tool drivingly connected with the motor, a power supply, a main control module electrically connected with the power supply and used for controlling the motor, and a tilt angle detecting module connected with the main control module. The tilt angle detecting module detects a tilt angle between the cutting tool and a horizontal plane. When the tilt angle is greater than a preset value, the tilt angle detecting module sends a shutdown signal to the main control module. The main control module turns off the power supply to stop the electric motor upon receipt of the shutdown signal. A related method of use is disclosed.
