Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing, and in particular to a smart home control device with a power-off protection function. Background Art

[0002] Smart home control devices use residences as platforms and home appliances and household appliances as the main control objects. They use integrated wiring technology, network communication technology, security technology, automatic control technology, and audio and video technology to efficiently integrate facilities related to home life, build an efficient control and management system for residential facilities and family schedule affairs, enhance home intelligence, safety, convenience, and comfort, and realize an integrated smart home network control system platform that is environmentally friendly and energy-saving. The smart home control system is the core of the smart home and the basis for the realization of smart home control functions.

[0003] Circuit breakers connect, disconnect and carry rated working current in the circuit, and can provide reliable protection when the line and motor are overloaded, short-circuited or under-voltaged. The moving and static contacts and contact rods of the circuit breaker are designed to be parallel, and the electric repulsion generated by the short circuit is used to disconnect the moving and static contacts. It has high breaking capacity and strong current limiting characteristics. When short-circuited, the aromatic insulation around the static contact vaporizes to cool and extinguish the arc, and the arcing distance is zero. The arc extinguishing chamber of the circuit breaker adopts a metal grid structure, and the contact system has a repulsion current limiting mechanism. Therefore, the circuit breaker has a high breaking capacity and current limiting capacity.

[0037] A movable block 303 is provided at the bottom of the second support frame 302. The present invention is provided with a smart home control device with a power-off protection function. When the control device continues to work, the motor 3012 at the bottom cools the controller body 3023 by rotating the cooling fan 3016, and cleans the second filter mesh 401 through the cleaning device 4 to prevent the second filter mesh 401 from being blocked and affecting the cooling effect. When the home control device continues to work and causes heat, the motor 3012 rotates the cooling fan 3016 through the rotating shaft 3013, and blows wind toward the controller body 3023 through the cooling fan 3016.

[0038] The top inner wall of the movable block 303 is fixedly connected to a third support frame 3032, one end of the third support frame 3032 away from the movable block 303 is fixedly connected to a third connecting ring 3031, the inner wall of the third connecting ring 3031 is provided with a second fixed leaf 3034, the second fixed leaf 3034 is fixedly connected to the third support frame 3032, and the top of the third support frame 3032 is fixedly connected to a fourth fixed shaft 3035.

The upper and lower ends of the sliding block 3037 are respectively fixedly connected with the first sliding shaft 3038, the first sliding shaft 3038 at the bottom is rotatably connected to the first rotating rod 3036, and the outer surface of the first sliding shaft 3038 at the top is movably sleeved with a second rotating rod 3039, and the end of the second rotating rod 3039 away from the sliding block 3037 is rotatably connected to the second fixed shaft 3025, and the same first spring 30310 is fixedly connected between the two sliding blocks 3037. The number of the third support frames 3032 is four, and the four third support frames 3032 are symmetrically arranged about the central axis of the third connecting ring 3031

[0040] A third fixed shaft 3033 is fixedly connected to the bottom of the movable block 303. The wind from the cooling fan 3016 passes through the first fixed blade 3022 and the second fixed blade 3034 to make the wind blow toward the controller body 3023 in a more concentrated manner. The first rotating rod 3036 and the second rotating rod 3039 on the third supporting frame 3032 on the inner wall of the movable block 303 are bent inwardly, so as to reduce the vibration of the sliding ring 3045 on the second supporting frame 302.

There are four second sliding shafts 3041 , which are symmetrically arranged about the central axis of the first filter mesh 304 . A first through hole 3047 is opened on the top of the first filter mesh 304 .

[0042] The outer surface of the second sliding shaft 3041 is movably sleeved with a third rotating rod 3042, and the end of the third rotating rod 3042 away from the second sliding shaft 3041 is provided with a fourth rotating rod 3043, and the middle axis of the fourth rotating rod 3043 is fixedly connected with a fifth fixed shaft 3044, and the fourth rotating rod 3043 is rotatably connected to the third rotating rod 3042 through the fifth fixed shaft 3044.

When the rotating shaft 3013 rotates, the convex point 3015 on the inner wall of the second groove 3014 contacts the sliding ring 3045, causing the sliding ring 3045 to shake, and the fourth rotating rod 3043 transmits the vibration to the first filter mesh 304 through the third rotating rod 3042, causing the first filter mesh 304 to shake, thereby shaking off the dust on the first filter mesh 304.

The third rotating rod 3042 connected to the first filter sheet 304 is rotatably connected to generate vibrations to the first filter sheet 304, so that dust on the first filter sheet 304 is shaken off, and upward wind is generated by the cooling fan 3016. When the third fixed leaf 402 is blown, the second filter sheet 401 fixedly connected to the third fixed leaf 402 is rotated, and the first arc rod 405 and the second arc rod 4051 connected to the first fixed shaft 102 are rotatably connected to clean the dust on the top of the second filter sheet 401 through the brush bristles 4052 at the bottom.
