Technical Field

[0001] This utility model relates to the field of electric actuator technology, specifically to an electric actuator assembly for an electric air valve in an open kitchen. Background Technology

[0002] In open kitchens, electrically operated air dampers are typically controlled by electric actuators. These actuators generally include intelligent electric actuators or those with built-in controllers, which receive electrical signals to control the opening and closing of the dampers, thus achieving automatic adjustment and control of the ventilation system. Over prolonged use, electric actuators can overheat, and cooling through ventilation holes is inefficient, potentially leading to thermal damage.

[0003] Chinese patent discloses an electric actuator (authorization announcement number CN207394081U). The main features of this patented technology include a housing with an output shaft vertically arranged inside. A handwheel assembly is mounted on the output shaft, comprising a handwheel and a worm gear. A sleeve is fitted onto the worm gear, and the sleeve has a protrusion with symmetrically arranged threaded holes. A connecting screw passes through the bushing of the worm gear and into the threaded hole of the protrusion. The handwheel includes a hub and a rim. Several spokes are arranged around the outer periphery of the hub, and the spokes are connected to the rim. A strip-shaped arc groove is provided on the rim between two adjacent spokes. A rib is provided in the arc groove, and a part of the rib extends out of the arc groove. A spring is provided between the rib and the bottom wall of the arc groove. A flange is provided on the inner wall of the arc groove. A raised ring is provided on the outer surface of the rib that abuts against the flange. The raised ring abuts against the flange. The rim also has four grooves for accommodating the operator's fingers.

[0004] However, this patent still has shortcomings. During prolonged use, the electric actuator can overheat, and cooling through the ventilation holes is inefficient, easily leading to thermal damage. Therefore, those skilled in the art have provided an electric actuator assembly for an electric air valve in an open kitchen to address the problems mentioned in the background section.

The mounting hole 30 facilitates the insertion and fixing of the pipe 13, and also facilitates the fixing of the pipe 13 and the box 3.

[0024] The upper surface of the housing 13 has a threaded groove 15, and the bottom of the inner wall of the threaded groove 15 has a circular groove 14. A threaded circular cover 16 extends into the threaded groove 15 and is threadedly connected. Handles 18 are fixed on both sides of the upper surface of the threaded circular cover 16.
