[0016] Embodiment 1, as Figure 1As shown, the utility model provides a technical solution: a lighting component of a heat-collecting magnetic stirrer, comprising a magnetic stirring cylinder protective shell 5 and a magnetic stirring glass cylinder body 1, the magnetic stirring glass cylinder body 1 is sleeved inside the magnetic stirring cylinder protective shell 5, the bottom of the magnetic stirring cylinder protective shell 5 includes a heating component, a magnetic force change component and a power control module, and is characterized in that: a concave annular groove recessed toward the inside of the magnetic stirring glass cylinder body 1 is provided on the bottom surface of the magnetic stirring cylinder protective shell 5, a temperature sensor 6 and a lighting board 3 are fixedly provided on the surface of the concave annular groove, a light homogenizing plate 4 is provided at the bottom of the lighting board 3, a microcontroller is also included in the magnetic stirring cylinder protective shell 5, and the temperature sensor 6 and the lighting board 3 are electrically connected to the microcontroller.
[0017] In a specific embodiment of the utility model, the microcontroller is connected to the heating component and the temperature sensor in the protective shell 5 of the magnetic stirring cylinder. The heating component is controlled by the current change to heat, and the current temperature is detected by the temperature sensor to realize a closed loop. The magnetic change component is in the magnetic stirring base. The magnetic change component is composed of a micro motor and a magnet. The magnet protrudes from the top of the base and is placed in the protective shell 5 of the magnetic stirring cylinder. The magnet is driven to rotate by the motor, so that the magnetic field in the magnetic stirring glass cylinder 1 is constantly changing. When the liquid to be stirred and the stirring magnet are placed in the magnetic stirring glass cylinder 1, the magnetic field changes continuously, causing the stirring magnet to rotate and stir rapidly in the liquid, thereby achieving the effect of magnetic stirring. The heating component is an annular heating tube, which is directly attached to the inner surface of the top of the protective shell 5 of the magnetic stirring cylinder, and can heat the liquid in the magnetic stirring glass cylinder 1. The microcontroller sets the program in advance, and the microcontroller processes the current heating working state. The green light is always on, indicating standby mode or stable temperature mode. The green light is breathing and flashing, indicating that heating is in progress. The red light is always on, indicating that the heating abnormality equipment has failed and needs to be investigated. The temperature monitored by the temperature sensor 6 is a continuously stable temperature (for example, the temperature is maintained above 10°C and maintained at 30°C, 35°C or 40°C, etc.), and the light board 3 is always green. When the temperature monitored by the temperature sensor 6 is a steadily rising temperature (for example, the temperature gradually increases from 20°C to 50°C), the light board 3 is in a green breathing and flashing state. When the temperature monitored by the temperature sensor 6 is a high temperature (over 90°C) or the heating component is turned on but the temperature is at 0°C for a long time, the light board 3 is always red.
[0018] In the preferred technical solution, the magnetic stirring glass cylinder 1 is embedded in the magnetic stirring cylinder protective shell 5 to play a protective role. The top of the magnetic stirring cylinder protective shell 5 and the magnetic stirring glass cylinder 1 are sealed to prevent leakage of the magnetic stirring glass cylinder 1. A retaining ring 2 is integrally formed on the outer side of the top of the magnetic stirring cylinder protective shell 5. The spacing between the retaining ring 2 and the magnetic stirring cylinder protective shell 5 is set to 10 mm. The top end face of the retaining ring 2 is flush with the top end face of the magnetic stirring glass cylinder body 1. A slot is formed between the retaining ring 2 and the magnetic stirring cylinder protective shell 5 for clamping with the cover body to improve stability after the cover is closed.
[0019] In the preferred technical solution, the light homogenizing plate 4 is a highly transparent polycarbonate plate, which has high light transmittance and uniform light scattering properties, and can effectively distribute the light of the light board 3 evenly on the surface of the light homogenizing plate 4, thereby achieving relatively uniform lighting. The light board 3 is FR-4 glass fiber flame-retardant material, which has the effect of high temperature resistance. The light board 3 and the light homogenizing plate 4 are embedded in the concave ring groove at the bottom of the protective shell 5 of the magnetic stirring cylinder to facilitate light observation.
[0020] In the preferred technical solution, an anti-skid pad is provided at the bottom of the magnetic stirring cylinder protective shell 5, which increases the friction when in contact with the table top. A groove for increasing the contact friction is provided around the vertical circumferential surface of the magnetic stirring cylinder protective shell 5, and the groove is provided to facilitate the hand to grasp the magnetic stirring cylinder protective shell 5.
[0021] In the preferred technical solution, a thermal insulation component is also provided at the bottom of the magnetic stirring cylinder protective shell 5. The thermal insulation component is located outside the heating component. A fence is provided at the center of the bottom of the magnetic stirring cylinder protective shell. The thermal insulation component and the heating component are both arranged in the fence. The thermal insulation component wraps the heating component to protect and insulate it. The thermal insulation component is flame-retardant and thermal insulating rock wool.
[0022] Working principle: The microcontroller is electrically connected to the heating component and temperature sensor in the enclosure of the magnetic stirring cylinder protective shell 5, and the heating component is controlled by the current change to heat. The temperature sensor detects the current temperature to achieve a closed loop. The magnetic change component is in the magnetic stirring base. The magnetic change component consists of a micro motor and a magnet. The magnet protrudes from the top of the base and is placed in the enclosure of the magnetic stirring cylinder protective shell 5. The motor drives the magnet to rotate, so that the magnetic field in the magnetic stirring glass cylinder 1 is constantly changing. When the liquid to be stirred and the stirring magnet block are placed in the magnetic stirring glass cylinder 1, the magnetic field changes continuously, so that the stirring magnet block rotates and stirs rapidly in the liquid, thereby achieving the effect of magnetic stirring. The heating component is a ring heating tube, which is directly attached to the inner surface of the top of the magnetic stirring cylinder protective shell 5, and can heat the liquid in the magnetic stirring glass cylinder 1. The microcontroller sets the program in advance, and the microcontroller processes the current heating working state.
