[0002] Three-phase smart meters with smoke alarms are composite devices combining power metering and fire early warning functions. They are widely used in industrial, commercial, and high-power residential applications. Their main functions include: power metering, accurately measuring three-phase active, reactive, and apparent energy, supporting forward / reverse metering; time-of-use billing, supporting peak, valley, and flat time-of-use rates to adapt to tiered pricing requirements; real-time monitoring, displaying voltage, current, power factor, frequency, and instantaneous power (active / reactive); data storage, recording historical electricity consumption data (such as monthly electricity consumption) for analysis and settlement; and event logging, recording abnormal events such as voltage loss, current loss, phase loss, and voltage fluctuations.

[0003] However, the lack of a cleaning device in the existing technology makes the filter screen of the smoke detector easy to be clogged by large impurities, affecting the normal use of the smoke detector.

[0024] Please see Figure 1 , 2 3, 4, 5, 6, This utility model discloses a three-phase smart meter with smoke alarm function, comprising a meter body 1, a smoke detector assembly 2 fixedly mounted on the lower surface of the meter body 1, a sensing cavity 3 mounted below the smoke detector assembly 2, a filter 4 disposed outside the sensing cavity 3, an annular brush 5 disposed outside the filter 4, a drive block 6 fixedly connected to both sides of the annular brush 5, the drive blocks 6 being symmetrically installed, a drive groove 7 being formed on the outer surface of each drive block 6, a first gear 8 disposed on one side of each drive block 6, the first gears 8 being symmetrically installed, and a drive pin 9 fixedly connected to the outer surface of each first gear 8. The meter body 1 is used to measure and monitor the power consumption in a three-phase AC power system, and the smoke detector assembly 2 contains an electric... The smoke detector assembly 2 includes components such as a circuit board, an infrared device, a buzzer, an LED warning light, and a control switch. The internal components of the smoke detector assembly 2 are electrically connected to the meter body 1. The infrared device corresponds to the top opening of the sensor 3. Under normal circumstances, the receiving module of the infrared device cannot receive the signal from the transmitting module. When smoke enters the interior of the sensing cavity 3, the infrared rays are scattered in the smoke, causing the receiving module to receive the infrared rays, thereby triggering the buzzer and LED warning light to alarm. The bristles of the annular brush 5 are in contact with the outer surface of the filter screen 4. Each drive pin 9 is located inside the corresponding drive groove 7. When the first gear 8 rotates, the first gear 8 drives the drive block 6 and the annular brush 5 to move up and down reciprocally through the drive pin 9 and the drive groove 7, thereby achieving the scraping and cleaning of the filter screen 3.

[0025] The outer surface of the annular brush 5 has four through holes, and a slide rod 10 is slidably connected inside each through hole. Both ends of each slide rod 10 are fixedly connected to the sensing cavity 3. The slide rod 10 supports and limits the annular brush 5, allowing the annular brush 5 to move up and down along the axis of the slide rod 10.

[0026] Each smoke sensor component 2 has a housing 11 fixedly installed on its lower surface. A chassis 12 is provided below the housing 11. The housing 11 has a hollow structure. The inner wall of the housing 11 is rotatably connected to the first gear 8. The housing 11 provides support and protection for components such as the sensing cavity 3. The chassis 12 seals the bottom of the housing 11 to catch the dust that falls.

[0027] The inner wall of the outer casing 11 is rotatably connected to two second gears 13, and a drive rod 14 is fixedly connected between the two second gears 13. The second gears 13 are symmetrically installed, and each second gear 13 meshes with a corresponding first gear 8.

A third gear 16 is fixedly connected to the output end of the motor. A fourth gear 17 is provided on one side of the third gear 16. The bottom shell 15 is fixedly connected to the inside of the outer shell 11. The motor is electrically connected to the control board of the smoke sensor assembly 2 through a control circuit. The fourth gear 17 is fixedly connected to the middle section of the drive rod 14. The third gear 16 and the fourth gear 17 mesh with each other. The drive rod 14 is rotatably connected to the inside of the bottom shell 15.

[0029] A positioning cylinder 18 is fixedly connected inside the chassis 12. A positioning pin 19 is sleeved inside the positioning cylinder 18. The top of the positioning pin 19 is fixedly connected to the bottom of the base shell 15. The positioning pin 19 and the positioning cylinder 18 provide auxiliary positioning for the installation of the chassis 12.

[0030] Two slots 20 are formed on the outer surface of the outer casing 11, and two clips 21 are fixedly connected to the outer surface of the chassis 12. The slots 20 are arc-shaped, and their arc centers are located on the axis of the positioning cylinder 18. Each clip 21 is matched with a corresponding slot 20, and the clips 21 are installed on the chassis 12 through the slots 20.

[0031] The implementation principle is as follows: when the motor is started, the output end of the motor drives the third gear 16 to rotate, the third gear 16 drives the fourth gear 17 to rotate, the fourth gear 17 drives the drive rod 14 to rotate, the drive rod 14 drives the second gear 13 to rotate, the second gear 13 drives the first gear 8 to rotate, the first gear 8 drives the drive pin 9 to rotate, and the drive pin 9 drives the drive block 6 and the annular brush 5 to move up and down reciprocally through the drive groove 7, scraping the outer surface of the filter screen 4 and scraping the impurities into the interior of the chassis 12.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
