Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a smart home control device with power failure protection function. Background Technology

[0002] Smart home control devices are based on residences as platforms, with home appliances and equipment as the main control objects. They utilize integrated wiring technology, network communication technology, security technology, automatic control technology, and audio-visual technology to efficiently integrate facilities related to home life, constructing an efficient control and management system for residential facilities and daily household affairs. This enhances the intelligence, safety, convenience, and comfort of the home, and achieves environmental protection and energy conservation. The smart home control system is the core of a smart home and the foundation for realizing smart home control functions.

[0003] Circuit breakers are used in circuits to make, break, and carry rated operating current, and provide reliable protection for lines and motors under overload, short circuit, and undervoltage conditions. The moving and stationary contacts and contact rods of a circuit breaker are designed in a parallel configuration. The electric repulsion force generated by a short circuit causes the moving and stationary contacts to open, resulting in high breaking capacity and strong current-limiting characteristics. During a short circuit, the aromatic insulation surrounding the stationary contact vaporizes, providing cooling and arc-extinguishing effects, resulting in zero arc distance. The arc-extinguishing chamber of the circuit breaker uses a metal grid structure, and the contact system has a repulsion current-limiting mechanism. Therefore, the circuit breaker has very high breaking capacity and current-limiting capacity.

[0004] Patent application number 202020860618.6 discloses a smart home control device with power failure protection function. When the control device is working continuously, it will generate heat. If the heat is not dissipated in time, it will cause the control device to overheat and reduce its performance. When cooling for a long time, dust is easy to accumulate in the heat dissipation area, which will block the heat dissipation holes and reduce the cooling effect.

[0005] Therefore, we propose a smart home control device with power outage protection function. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: See Figures 1-6 The present invention provides a technical solution: a smart home control device with power failure protection function, comprising a housing 1, four support feet 2 fixedly connected to the bottom outer wall of the housing 1, the four support feet 2 being symmetrically arranged about the central axis of the housing 1, a first groove 101 formed on the top inner wall of the housing 1, two first fixing shafts 102 fixedly connected to the inner wall of the first groove 101, the two first fixing shafts 102 being symmetrically arranged about the central axis of the first groove 101, a first sliding groove 103 formed on the upper inner wall of the housing 1, and further comprising:

[0032] The heat dissipation device 3 includes a first support frame 301 fixedly connected to the inner wall of the bottom of the housing 1. A first connecting ring 3011 is fixedly connected to the end of the first support frame 301 away from the housing 1. A second support frame 302 is fixedly connected to the inner wall of the central axis of the housing 1. A motor 3012 is fixedly connected to the inner wall of the first connecting ring 3011. A rotating shaft 3013 is fixedly connected to the output end of the motor 3012. A cooling fan 3016 is fixedly connected to the end of the rotating shaft 3013 away from the motor 3012. A second groove 3014 is provided at the central axis of the rotating shaft 3013. A protrusion 3015 is fixedly connected to the inner wall of the bottom of the second groove 3014. A first filter screen 304 is provided at the bottom of the first support frame 301.

[0033] The cleaning device 4 includes a second filter screen 401 slidably connected to the first sliding groove 103. A first fixing block 403 is fixedly connected to the top of the second filter screen 401. A fourth groove 404 is provided at the central axis of the first fixing block 403. A third fixing leaf 402 is fixedly connected to the bottom of the second filter screen 401. A second fixing block 4054 is provided inside the fourth groove 404. A second through hole 406 is provided at the top of the second filter screen 401.

[0034] A roller 4055 is rotatably connected to the left side of the second fixed block 4054 via a pivot. A second arc-shaped rod 4051 is rotatably connected to the right side of the second fixed block 4054 via a pivot. A first arc-shaped rod 405 is rotatably connected to the end of the second arc-shaped rod 4051 away from the second fixed block 4054 via a pivot. The first arc-shaped rod 405 and the second arc-shaped rod 4051 are merely names and do not represent their shape or other characteristics. Brush bristles 4052 are fixedly connected to the bottom of the first arc-shaped rod 405 and the end of the first arc-shaped rod 405 away from the second arc-shaped rod 4051 is rotatably connected to the first fixed shaft 102. A second spring 4053 is fixedly connected between the two first arc-shaped rods 405.

[0035] This invention incorporates a cleaning device 4. The bottom roller 4055 of the second fixing block 4054 contacts the first fixing block 403. The irregular shape of the first fixing block 403 causes rotation between the first arc-shaped rod 405 and the second arc-shaped rod 4051. This rotation of the second filter screen 401 causes the bottom bristles 4052 of the first and second arc-shaped rods 4055 to contact the second through hole 406. The motor 3012 is independent of the second filter screen 401. The rotation of the filter screen 401 is achieved by the upward airflow generated by the cooling fan 3016, which causes the third fixing blade 402, fixedly connected to the bottom of the second filter screen 401, to rotate, thereby rotating the second filter screen 401. The rotation achieves the effect of dust removal. The second filter screen 401 rotates along the first sliding groove 103 through the third fixed leaf 402 at the bottom of the second filter screen 401. When the second filter screen 401 rotates, the movement between the fourth groove 404 inside the first fixed block 403 and the roller 4055 causes the first arc rod 405 and the second arc rod 4051 to vibrate when the roller 4055 contacts the irregularly shaped first fixed block 403. The brush bristles 4052 at the bottom of the first arc rod 405 and the second arc rod 4051 clean the second filter screen 401, preventing the second filter screen 401 from becoming clogged and affecting the heat dissipation effect.

[0036] Example 2: Please refer to Figures 7-9 Based on Embodiment 1, the present invention provides the following technical solution: A second connecting ring 3021 is fixedly connected to one end of the second support frame 302 away from the housing 1; a controller body 3023 is fixedly connected to the inner wall of the second connecting ring 3021; ​​a first fixing leaf 3022 is provided on the outer side of the second connecting ring 3021; ​​the first fixing leaf 3022 is fixedly connected to the second support frame 302; a third groove 3024 is provided at the bottom of the second support frame 302; a second fixing shaft 3025 is fixedly connected to the inner wall of the third groove 3024.

[0037] The bottom of the second support frame 302 is provided with a movable block 303. The present invention provides a smart home control device with power failure protection function. When the control device is working continuously, the motor 3012 at the bottom rotates the cooling fan 3016 to cool the controller body 3023. The cleaning device 4 cleans the second filter screen 401 to prevent the second filter screen 401 from becoming clogged and affecting the cooling effect. When the home control device is working continuously and causes heat, the motor 3012 rotates the cooling fan 3016 through the rotating shaft 3013, and the cooling fan 3016 blows air towards the controller body 3023.

[0038] A third support frame 3032 is fixedly connected to the top inner wall of the movable block 303. A third connecting ring 3031 is fixedly connected to the end of the third support frame 3032 away from the movable block 303. A second fixing blade 3034 is provided on the inner wall of the third connecting ring 3031. The second fixing blade 3034 is fixedly connected to the third support frame 3032. A fourth fixing shaft 3035 is fixedly connected to the top of the third support frame 3032. By providing a first fixing blade 3022 and a second fixing blade 3034, when the cooling fan 3016 blows air towards the controller body 3023, the tilt angle of the first fixing blade 3022 and the second fixing blade 3034 allows the air to be blown more effectively onto the controller body 3023, thereby improving the cooling effect.

[0039] A first rotating rod 3036 is movably sleeved on the outer surface of the fourth fixed shaft 3035. A sliding block 3037 is provided at the end of the first rotating rod 3036 away from the fourth fixed shaft 3035. The upper and lower ends of the sliding block 3037 are respectively fixedly connected to the first sliding shaft 3038. The first sliding shaft 3038 at the bottom is rotatably connected to the first rotating rod 3036. A second rotating rod 3039 is movably sleeved on the outer surface of the first sliding shaft 3038 at the top. The end of the second rotating rod 3039 away from the sliding block 3037 is rotatably connected to the second fixed shaft 3025. The same first spring 30310 is fixedly connected between the two sliding blocks 3037. There are four third support frames 3032, which are symmetrically arranged about the central axis of the third connecting ring 3031.

[0040] The bottom of the movable block 303 is fixedly connected to a third fixed shaft 3033. The air from the cooling fan 3016 is directed towards the controller body 3023 by the first fixed blade 3022 and the second fixed blade 3034. The inward bending of the first rotating rod 3036 and the second rotating rod 3039 on the third support frame 3032 on the inner wall of the movable block 303 reduces the vibration of the sliding ring 3045 on the second support frame 302.

[0041] The top inner wall of the first filter screen 304 is fixedly connected with a second sliding shaft 3041. There are four second sliding shafts 3041, which are symmetrically arranged about the central axis of the first filter screen 304. The top of the first filter screen 304 is provided with a first through hole 3047.

[0042] A third rotating rod 3042 is movably sleeved on the outer surface of the second sliding shaft 3041. A fourth rotating rod 3043 is provided at the end of the third rotating rod 3042 away from the second sliding shaft 3041. A fifth fixed shaft 3044 is fixedly connected to the central axis of the fourth rotating rod 3043. The fourth rotating rod 3043 is rotatably connected to the third rotating rod 3042 through the fifth fixed shaft 3044.

[0043] The right side of the fourth rotating rod 3043 is rotatably connected to the third fixed shaft 3033. A sliding ring 3045 is provided at the end of the fourth rotating rod 3043 away from the third fixed shaft 3033. The outer wall of the sliding ring 3045 is fixedly connected to the third sliding shaft 3046, and the inner wall of the sliding ring 3045 is slidably connected within the second groove 3014.

[0044] This invention incorporates a heat dissipation device 3. Driven by the rotating shaft 3013 of the motor 3012, a cooling fan 3016 cools the controller body 3023. The protrusions 3015 on the inner wall of the second groove 3014 vibrate the sliding ring 3045, and the fourth rotating rod 3043 and the third rotating rod 3042 vibrate the first filter screen 304, causing dust to be shaken off. When the rotating shaft 3013 rotates, the protrusions 3015 on the inner wall of the second groove 3014 contact the sliding ring 3045, causing it to vibrate. The fourth rotating rod 3043 transmits the vibration to the first filter screen 304 through the third rotating rod 3042, causing the first filter screen 304 to vibrate and thus shake off the dust.

[0045] When cooling of the controller body 3023 is required, the motor 3012 at the bottom causes the cooling fan 3016 to blow air upwards. The tilt angle of the first fixed blade 3022 and the second fixed blade 3034 ensures the airflow is more centrally focused, carrying away heat from the controller body 3023. When the airflow blows on the second fixed blade 3034, the third support frame 3032, which is fixedly connected to the second fixed blade 3034, vibrates. This vibration is transmitted through the third fixed shaft 303 at the bottom of the third support frame 3032. The third rotating rod 3042, which is rotatably connected, vibrates the first filter screen 304, causing the dust on the first filter screen 304 to fall off. The cooling fan 3016 generates an upward airflow, which blows the third fixed blade 402. When the third fixed blade 402 is fixedly connected to the third fixed blade 402, the second filter screen 401 rotates. The first arc-shaped rod 405 and the second arc-shaped rod 4051, which are rotatably connected to the first fixed shaft 102, clean the dust on the top of the second filter screen 401 through the brush bristles 4052 at the bottom.
