The torsion spring 255 is sleeved on the long shaft 253, and the two ends of the torsion spring 255 are respectively fixed on the right fixing seat 120 and the left fixing seat 130. The function of the torsion spring 255 is to provide assistance when the dining stove cover 310 is opened and to provide impedance when the dining stove cover 310 is closed to protect the motor from overload.

[0061] The right fixing seat 120 includes a right fixing seat shell 121 and a right fixing seat cover 122;

[0062] One end of the upper side of the box body 100 is fixedly connected to the right fixing seat shell 121 by screws, and one side of the right fixing seat shell 121 is fixedly connected to the right fixing seat cover 122 by screws.

[0063] The left fixing seat 130 includes a left fixing seat shell 131 and a left fixing seat cover 132;

[0064] The other end of the upper side of the box body 100 is fixedly connected to the left fixed seat shell 131 by screws, and one side of the left fixed seat shell 131 is fixedly connected to the left fixed seat cover 132 by screws.

[0065] Working principle: During the process of automatically opening the dining oven cover 310, the motor 211 rotates forward, the worm 1 212 moves and drives the gear 1 222 to rotate. At this time, the gear 1 222 and the worm 2 223 rotate synchronously, and the rotation of the worm 2 223 drives the gear 2 232 to rotate. At this time, the gear 2 232 and the gear 3 234 rotate synchronously. The rotation of the gear 3 234 drives the gear 4 257 to rotate through the tooth chain 240. At this time, the one-way clutch sprocket (one-way bearing 256) is tightened, and then the ratchet mechanism clamps the flip mechanism 140 to push the dining oven cover 310 to open. During this process, the torsion spring 255 provides assistance.

[0066] During the process of automatically closing the dining oven cover 310, the motor 211 reverses. At this time, the outer ring of the one-way clutch sprocket rotates idly (the long shaft 253 remains stationary), and the ratchet mechanism (disengages idling). The dining oven cover 310 relies on its own weight (the long shaft 253 only serves as a brake to adjust the descent speed) to finally close the dining oven cover 310. During this process, the worm gear provides closing resistance, and the torsion spring 255 provides resistance.

[0067] In this structure, if an obstacle is encountered during the closing process of the dining oven cover 310, the motor 211 continues to rotate. Due to the existence of the ratchet mechanism, the motor 211 becomes idling, causing the current to increase. The sensor detects the current increase and feeds it back to the power supply control board 200 to stop the motor 211, thereby effectively protecting the motor 211 from overload and burnout. At the same time, the dining oven cover 310 can be opened manually, effectively preventing pinching.

[0068] In the closing process of the dining oven cover 310, if there is a power outage or sudden power failure under special circumstances, the one-way bearing 256 can effectively prevent the dining oven cover 310 from closing suddenly due to gravity; at the same time, the reverse self-locking of the worm gear provides impedance.

[0069] When the external infrared sensor senses a human body, the motor 211 opens the dining oven cover 310, and when the external infrared sensor no longer senses a human body, the dining oven cover 310 is closed.

[0070] in:

[0071] 1. Time presetting: control the opening time (7 seconds) or slightly longer;

[0072] 2. Close: Self-weight + brake; (14 seconds)

[0073] 3. After opening the lid, it will automatically shut down in 30 seconds (preset) or slightly shorter if there is no induction;

[0074] 4. Infrared static sensing, the cover will open automatically after 2 seconds;

[0075] 5. Infrared sensor, sensing wide angle: 120 degrees;

[0076] 6.Infrared sensing distance: 0.8 meters.

[0077] The rotator of the present invention is suitable for, but not limited to, dining stoves as an independent product. The power supply electronic control board 200 controls the motor 211, the two-stage worm gear transmission (transmission ratio: 1:20; 1:30) and the chain transmission to achieve the effect of automatically controlling the rotation of the mechanism. The infrared sensor is electrically connected to achieve the effect of induction automatic switching.

[0078] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
