Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, and in particular to an electric vacuum suction cup. Background Technology

[0002] Electric suction cups are a common material handling tool. They work by attaching a seal at the bottom of the suction cup to the object being handled, then removing the air between the base and the object to create a vacuum. This seal allows the suction cup to adhere tightly to the object, achieving the desired handling effect. After the suction cup completes its handling, the vacuum chamber between the base and the object is depressurized, breaking the negative pressure vacuum and allowing the suction cup base to detach freely from the object.

[0003] CN215287040U discloses an electric vacuum suction cup, including a chassis with an air extraction port and a release port; a sealing ring installed at the lower end of the chassis, forming a vacuum adsorption zone with the lower end of the chassis; one end of the air extraction port and the release port are both connected to the vacuum adsorption zone; a vacuum pump fixed relative to the chassis, with its extraction end sealed to the air extraction port; the vacuum pump is used to extract air from the vacuum adsorption zone, thereby allowing the chassis to adhere to an object; a handle fixed to the chassis; and a release element cooperating with the release port to control the opening and closing of the release port. When the release element is working, it allows external gas to enter the vacuum adsorption zone through the release port, thereby disrupting the negative pressure environment of the vacuum adsorption zone and allowing the chassis to detach from the object. While this technical solution can achieve vacuum adsorption operation of the suction cup, its base and handle need to be assembled and fixed, making the assembly of the electric vacuum suction cup relatively complex. At the same time, the seal and the base are also assembled and fixedly connected, making their assembly relatively complex and the sealing performance generally poor. Therefore, an electric vacuum suction cup is provided to solve the above problems. Utility Model Content
