One end of the heat conduction rod is fixed on the mirror and the mounting block is fixed At the other end of the heat-conducting rod, there is a gap between the mounting block and the connecting box, and the stirring rod assembly corresponds to the heating rod one-to-one; the energy-saving structure includes three energy-saving components, which correspond to the heat-conducting rod one-to-one. Between the block and the connecting box; the energy-saving component includes a fixed pipe, a moving pipe and two moving units. The fixed pipe and the moving pipe are coaxially arranged with the heat conducting rod. The inner diameter of the moving pipe is larger than the diameter of the heat conducting rod. The inner diameter of the fixed pipe is equal, one end of the fixed pipe is sealed and fixedly connected with the connecting box, a gap is provided between the other end of the fixed pipe and the mounting block, the moving pipe is set in the fixed pipe, and the moving pipe is slid and sealed with the inner wall of the fixed pipe , A gap is provided between one end of the moving pipe and the connecting box, the other end of the moving pipe abuts against the mounting block and is connected in a sealed manner, the moving unit is arranged in the fixed pipe, the moving unit is located between the moving pipe and the connecting box, and the power unit drives the moving pipe Move along the axial direction of the thermally conductive rod. In order to improve the heat uniformity of the heat conduction rod, the mixing assembly includes a mounting hole, a stir bar, a Rotating shaft, a bearing, and a power unit. The Rotating shaft is parallel to the heat conduction rod. The mounting hole is set on the side of the connecting box away from the mirror. The mounting hole and rotation The shaft is arranged coaxially, the diameter of the mounting hole is equal to the diameter of the rotating shaft, the rotating shaft passes through the mounting hole, the rotating shaft is sliding and sealingly connected with the inner wall of the mounting hole, the axis of the stir bar is perpendicular to and intersects with the axis of the rotating shaft, the stir bar The middle end of the bearing is fixed on the side of the rotating shaft close to the mirror, the bearing and the power unit are arranged on the side of the connecting box away from the mirror, the inner ring of the bearing is installed on the rotating shaft, and the outer ring of the bearing is fixedly connected to the connecting box. The power unit is drivingly connected with the rotating shaft. In order to improve the heat dissipation efficiency, a fan blade is provided at the end of the rotating shaft away from the cheap led mirror.
In order to drive the rotating shaft to rotate, the power unit includes a drive motor, a drive gear and a driven gear. The power motor is fixed on the connecting box, the power motor is connected to the drive gear, the drive gear meshes with the driven gear, and the driven gear is installed on the rotating shaft. . In order to increase the rotational speed of the rotating shaft, the number of teeth of the driving gear is greater than the number of teeth of the driven gear. In order to increase the driving force of the drive motor, the drive motor is a servo motor. In order to drive the moving tube to move, the moving unit includes an electromagnet, a sliding rod, a connecting block, a fixed block, a spring and a supporting block. The sliding rod is parallel to the heat conducting rod. The connecting block is fixed on the end of the sliding rod close to the mirror and the other end of the sliding rod. The fixed block is fixed on the inner wall of the moving pipe. The support block is located between the connecting block and the moving pipe. The support block is provided with a through hole. The through hole is arranged coaxially with the sliding rod. The diameter of the through hole is equal to the diameter of the sliding rod. The sliding rod passes through the through hole, the sliding rod is slidably connected to the inner wall of the through hole, the connecting block abuts against the supporting block, a gap is provided between the moving tube and the supporting block, the spring is located between the supporting block and the fixed block, and the supporting block passes through the spring Connected to the fixed block, the electromagnet is arranged on the side of the connecting block away from the sliding rod, the electromagnet and the connecting block are arranged directly opposite, and the electromagnet is fixed on the connecting box. There is a gap between the electromagnet and the connecting block. The material is iron.
In order to reduce the friction between the sliding rod and the support block, the sliding rod is coated with lubricating oil. In order to realize intelligence, a temperature and humidity sensor and PLC are provided on the connection box, and the temperature and humidity sensor, heating rod, drive motor and electromagnet are all electrically connected to the PLC. In order to prolong the service life of the connecting box, an anticorrosive galvanized layer is provided on the inner wall of the connecting box. The energy-saving bathroom mirror with water mist removal function realizes the function of removing the water mist on the mirror through the heating mechanism. Compared with the existing heating mechanism, the heating mechanism also achieves the dual functions of cleaning the water mist and heating the bathroom water, which is more practical. Not only that, but also realizes the heating function through the energy-saving mechanism. Compared with the existing energy-saving mechanism, the energy-saving mechanism uses the heated bathroom water as the heating source, which is more energy-saving and environmentally friendly.
