A limiting rod 36 is passed through the center of the support column 31, and the outer surface of the limiting rod 36 contacts the upper surface of the electronic balance body 1. First, pull out the limiting rod 36, and then make the bottom of the drain pan 32 contact with the upper surface of the weighing pan of the electronic balance body 1, and then the overall weight of the drain assembly 3 can be obtained. After pressing the peeling key, the weight to be weighed is A heavy object is placed on the absorbent cloth 35 for weighing, and the weight of the object and the weight of the water can be obtained. At the same time, the absorbent cloth 35 will absorb part of the excess moisture on the outer surface of the object, and more moisture will flow to the bottom of the filter grid 34. At this time, the weighing object can be taken away, and the drain assembly 3 can be lifted up, and the limit rod 36 can be inserted into the inside of the support column 31, so that the drain tray 32 leaves the weighing tray of the electronic balance body 1, and then a new value can be obtained, that is, the remaining excess water weight. The value obtained from the last weighing minus the water value can more accurately obtain the weight of the object, and then the heating plate 33 can be started to dry the inside of the drain tray to avoid affecting the next weighing.

[0026] Blocks 4 are provided on both sides of the filter grid 34, and corresponding slots 41 are provided on the inner wall of the drain tray 32. The outer surface of the block 4 is engaged with the inside of the slot 41, so as to facilitate the disassembly and assembly of the filter grid 34 and the maintenance of the drain assembly 3.

[0027] Fixed columns 5 are provided on both sides of the filter grid 34, one end of the fixed column 5 passes through the interior of the absorbent cloth 35, and the bottom of the absorbent cloth 35 contacts the upper surface area of ​​the filter grid 34.

[0028] Sliding doors 6 are hinged on both sides of the transparent protective cover 2 to prevent dust from entering the electronic balance. By opening the sliding doors 6, it is convenient to place objects on the upper surface of the electronic balance body 1 and to remove the limit rod 36.

[0029] The inner wall of the transparent protective cover 2 is provided with a micro fan 7, which can help to blow away the hot air in the transparent protective cover 2 and accelerate the evaporation of water, thus helping to improve the long-term stability of the weighing equipment.

[0030] A temperature sensor 8 is provided inside the drain pan 32 to monitor the temperature of the surface of the heating plate 33 in real time to prevent the heating temperature from being too high, thereby damaging the equipment.

[0031] A control panel 9 is provided on the upper surface of the electronic balance body 1. The weighing plate, micro fan 7 and temperature sensor 8 of the electronic balance body 1 are all connected to the control panel 9 by signal, which can not only clearly display the weighing result, but also realize the regulation of the internal temperature of the drain component 3.

[0032] Specifically, first open the sliding doors 6 on both sides of the transparent protective cover 2, pull out the limit rod 36 inside the support column 31, so that the bottom of the drain pan 32 is in contact with the upper surface of the weighing pan of the electronic balance body 1, and then the overall weight of the drain assembly 3 is obtained. After pressing the tare key, the object to be weighed is placed on the absorbent cloth 35 for weighing, thereby obtaining the weight of the object and the weight of the water. At the same time, the absorbent cloth 35 will absorb part of the excess moisture on the outer surface of the object, and more moisture will flow to the bottom of the filter mesh 34. At this time, the object to be weighed can be taken away, the drain assembly 3 can be lifted up, and the limiting rod 36 can be inserted into the interior of the supporting column 31, so that the drain tray 32 can leave the weighing tray of the electronic balance body 1. At this time, a negative gram weight can be obtained, that is, the weight of water. The weight of the object can be more accurately obtained by subtracting the weight of water from the value obtained by the last weighing. According to the accuracy of the electronic balance itself, if the water content is small, it can be ignored. Then, the heating plate 33 can be started to dry the inside of the drain tray. To avoid affecting the next weighing, and because the inner wall of the transparent protective cover 2 is provided with a micro fan 7, the micro fan 7 can help blow away the hot air in the transparent protective cover 2, and can also accelerate the evaporation of water, which is helpful to improve the long-term stability of the weighing equipment. At the same time, a temperature sensor 8 is provided inside the drain pan 32, so the temperature of the surface of the heating plate 33 can be monitored in real time to avoid the heating temperature being too high, thereby damaging the equipment. In addition, since blocks 4 are provided on both sides of the filter grid 34, the inner wall of the drain pan 32 is correspondingly provided with a card slot 41, the outer surface of the block 4 is engaged with the inner part of the card slot 41, and fixed columns 5 are provided on both sides of the filter grid 34, one end of the fixed column 5 passes through the inside of the absorbent cloth 35, and the bottom of the absorbent cloth 35 contacts the upper surface area of ​​the filter grid 34. Therefore, by fixing the absorbent cloth 35 on the upper surface of the filter grid 34 with the fixed column 5, the items can be stably placed on the upper surface of the absorbent cloth 35, and it is convenient to replace the absorbent cloth 35, and it is also convenient to disassemble and assemble the filter grid 34, and then it is convenient to repair the drain assembly 3.
