[0027] The following is combined with Figure 1-5 The utility model is further described.

[0028] In order to solve the problems existing in the background technology, the present application proposes the following technical scheme: it includes an electronic balance body 1, on which a weighing pan 2 is arranged, the weighing pan 2 is used to weigh chemicals, a slide groove 3 is opened at the upper end of the electronic balance body 1, a support frame 4 is slidably installed on the slide groove 3, two groups of fixed plates 5 are fixedly connected under the support frame 4, a rotating rod 6 is rotatably installed in the two groups of fixed plates 5, a cleaning brush 7 is fixedly installed on the outer surface of the rotating rod 6, gears 8 are fixedly connected at both ends of the rotating rod 6, a tooth plate 13 is meshed under the gear 8, and the tooth plate 13 is fixedly installed on the upper surface of the electronic balance body 1.

[0029] After the weighing chemicals are taken away from the weighing pan 2, some chemicals may be spilled on the weighing pan 2 and the electronic balance body 1, affecting the weighing accuracy of the electronic balance body 1 when used next time. The support frame 4 is pushed to make the support frame 4 slide on the slide groove 3, and the support frame 4 drives the fixed plate 5, the rotating rod 6 rotating in the fixed plate 5 and the cleaning brush 7 fixedly connected to the rotating rod 6 to move. The cleaning brush 7 moves to clean the spilled chemicals. The soft bristles of the cleaning brush 7 can clean the upper end of the electronic balance body 1 and the weighing pan 2 at the same time. While the support frame 4 drives the cleaning brush 7 to move, the rotating rod 6 drives the gear 8 to move, and the gear 8 is meshed with the tooth plate 13. The tooth plate 13 causes the gear 8 to rotate, and the gear 8 drives the rotating rod 6 and the cleaning brush 7 to rotate, so that the cleaning brush 7 moves and rotates at the same time, thereby improving the cleaning effect of the spilled chemicals.

[0030] It is further explained that a motor 12 is fixedly installed inside the electronic balance body 1, a threaded rod 11 is fixedly connected to the driving shaft of the motor 12, the threaded rod 11 is rotatably installed in the slide groove 3, a slider 9 is threadedly sleeved on the outside of the threaded rod 11, and the slider 9 is fixedly connected to the lower end of the support frame 4.

[0031] The motor 12 drives the threaded rod 11 to rotate, the threaded rod 11 pushes the slider 9 to move on the threaded rod 11, and the slider 9 drives the support frame 4 to move so that the cleaning brush 7 cleans the spilled chemicals. The arrangement of the motor 12, the threaded rod 11 and the slider 9 improves the convenience of the cleaning brush 7 in cleaning chemicals.

[0032] It is further explained that a limiting groove 14 is provided on one side of the slide groove 3 , a limiting block 10 is slidably installed in the limiting groove 14 , and the limiting block 10 is fixedly connected to the side surface of the sliding block 9 .

[0033] The limiting groove 14 cooperates with the limiting block 10 to guide and limit the movement of the slider 9, thereby preventing the slider 9 from rotating when the threaded rod 11 rotates, improving the stability of the slider 9 when moving in the slide groove 3, and thus improving the stability of the cleaning brush 7 in cleaning chemicals.

[0034] It is further explained that a ventilation cavity 18 is opened inside the electronic balance body 1, and an air outlet slot 15 is opened on the side of the electronic balance body 1 away from the support frame 4. The air outlet slot 15 is connected to the inside of the ventilation cavity 18. A mounting plate 16 is fixedly connected to the ventilation cavity 18, and a fan 17 is fixedly installed on the mounting plate 16.

[0035] When the cleaning brush 7 cleans the chemicals spilled on the electronic balance body 1 and the weighing pan 2 to one side of the electronic balance body 1, the fan 17 blows air toward the air outlet slot 15 to generate negative pressure in the ventilation cavity 18, so that the upper opening of the ventilation cavity 18 generates suction to absorb the chemicals swept to one side of the electronic balance body 1 into the ventilation cavity 18, thereby completely cleaning the chemicals spilled on the electronic balance body 1 and the weighing pan 2.

[0036] It is further explained that a mounting groove 21 is opened on the side wall of the ventilation cavity 18, a collection frame 20 is slidably installed in the mounting groove 21, a filter screen 22 is fixedly connected to the bottom of the collection frame 20, and a handle 23 is fixedly installed on one side of the collection frame 20.

[0037] After the chemicals sucked by the fan 17 enter the ventilation chamber 18, the filter 22 separates them and makes the chemicals fall into the collection frame 20. The collection frame 20 collects the spilled chemicals. The collection frame 20 can be pulled out from the inside of the electronic balance body 1 through the handle 23. The chemicals collected by the collection frame 20 can be reused to avoid waste of chemicals.

[0038] It is further explained that a baffle 19 is fixedly mounted on the electronic balance body 1, and the baffle 19 is arranged above the air outlet slot 15. The baffle 19 can block the chemicals cleaned by the cleaning brush 7 to prevent the chemicals from falling outside the electronic balance body 1 and increasing the difficulty of cleaning. At the same time, the baffle 19 guides the cleaned chemicals to fall into the ventilation cavity 18.

[0039] Specific reference is made to the following operation: After the electronic balance body 1 and the weighing pan 2 are taken away after weighing the chemicals, some chemicals may be spilled on the weighing pan 2 and the electronic balance body 1. Start the motor 12, the motor 12 drives the threaded rod 11 to rotate, the threaded rod 11 pushes the slider 9 to move on the threaded rod 11, the slider 9 drives the support frame 4 to move, the support frame 4 drives the fixed plate 5, the rotating rod 6 rotating in the fixed plate 5 and the cleaning brush 7 fixedly connected to the rotating rod 6 to move, and at the same time the rotating rod 6 drives the gear 8 to move, the toothed plate 13 makes the gear 8 rotate, the gear 8 drives the rotating rod 6 and the cleaning brush 7 The brush 7 rotates, so that the cleaning brush 7 moves and rotates at the same time to clean the chemicals spilled on the electronic balance body 1 and the weighing pan 2. The cleaning brush 7 sweeps the chemicals to one side of the electronic balance body 1, and the fan 17 blows air to the air outlet slot 15 to generate negative pressure in the ventilation cavity 18, so that the upper opening of the ventilation cavity 18 generates suction to absorb the chemicals swept to one side of the electronic balance body 1 into the ventilation cavity 18, and the filter net 22 separates the chemicals and makes the chemicals fall into the collection frame 20, and the collection frame 20 collects the spilled chemicals to avoid waste of chemicals.
