[0007] The water spraying mechanism is located on the surface of the base frame and sprays water by pressing to rinse and clean the inner wall of the beaker.

[0008] The cleaning mechanism includes a vertical shaft, which is connected to the surface of the motor output shaft via a disconnection structure. Two horizontal shafts are fixedly connected to the surface of the vertical shaft, and the pair of horizontal shafts are symmetrically distributed around the central axis of the vertical shaft.

[0017] 1. This utility model involves turning on the motor, then inverting the beaker onto the surfaces of upright plate one and upright plate two, controlling the motor to start, and driving the two upright plates to rotate through the disconnection mechanism. This causes the two upright plates to drive the sponge to clean the inner wall of the beaker.

The side teeth between the main shaft and the auxiliary shaft act as a limit to prevent the shaft from reversing. The two baffles prevent the connecting rope from getting stuck between the main shaft and the auxiliary shaft. The rectangular slide bar ensures that it cannot rotate while sliding back and forth under the action of the spring. When the two uprights need to be reset, the slide bar is slid away from the upright shaft to release the limit on the main shaft, and the two uprights are reset under the action of the spring.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-4 As shown, an experimental instrument cleaning device includes a base frame 1 and a motor 3. The motor 3 is installed inside the base frame 1, and the output shaft of the motor 3 passes through the base frame 1 and is rotatably connected. The base frame 1 is used to install the motor 3 and support the overall structure.

[0028] It also includes a water spraying mechanism 2, a cleaning mechanism, and a disconnection mechanism;

[0029] The water spraying mechanism 2 is installed on the surface of the base frame 1 and sprays water by pressing to rinse and clean the inner wall of the beaker.

[0030] The cleaning mechanism includes a vertical shaft 5, which is connected to the surface of the output shaft of the motor 3 via a disconnection structure. Two horizontal shafts 6 are fixedly connected to the surface of the vertical shaft 5. The pair of horizontal shafts 6 are symmetrically distributed around the central axis of the vertical shaft 5. The ends of the two horizontal shafts 6 are respectively fixedly connected to a first vertical plate 7 and a second vertical plate 4. The first vertical plate 7 is "L" shaped. Both the first vertical plate 7 and the second vertical plate 4 are provided with sponge wipes on their surfaces.

[0031] When cleaning the experimental instruments during operation, the motor 3 is turned on, and the beaker is placed upside down on the surfaces of the first vertical plate 7 and the second vertical plate 4. The motor 3 is then started, and the two vertical plates are rotated by the disconnection mechanism. This causes the two vertical plates to move the sponge to clean the inner wall of the beaker. At the same time, the water spray mechanism 2 is pressed to wet the inner wall of the beaker, thereby improving the cleaning effect. The "L"-shaped first vertical plate 7 can clean the bottom surface of the beaker.

[0032] The disconnection mechanism includes a connecting shaft 12, a vertical shaft 5 fixedly connected to the surface of the connecting shaft 12, a locking block 13 fixedly connected to the surface of the connecting shaft 12, a plurality of locking blocks 24 fixedly connected to the surface of the output shaft of the motor 3, a crossbar 11 fixedly connected to the surface of the vertical shaft 5, a telescopic shaft 25 slidably connected to the surface of the crossbar 11 via a spring, the telescopic shaft 25 slidably connected to the surface of the base frame 1 via a sliding assembly, the sliding assembly including a rotating plate 26, a rotating groove 27 opened on the surface of the base frame 1, the rotating plate 26 slidably connected in the rotating groove 27, a locking bead 28 rotatably connected to the surface of the rotating plate 26, at least three locking beads 28 are provided, and they are equidistantly distributed, and the sides of the locking blocks 13 and 24 that are close to each other are both provided with rounded corners;

[0033] During operation, when the beaker is inverted on the surface of the vertical plate, the bottom of the beaker will press against the vertical plate, causing the vertical plate to move downwards. At the same time, the vertical plate 7 will drive the vertical shaft 5 to move, causing the vertical shaft 5 to drive the connecting shaft 12 to move downwards. This causes the locking block 13 to lock onto the surface of the locking block 14, allowing the output shaft of the motor 3 to drive the connecting shaft 12. The connecting shaft 12 then drives the vertical shaft 5 to rotate. When the beaker is removed, the spring drives the crossbar 11, which in turn drives the vertical shaft 5, causing the locking blocks 13 and 14 to disengage. This disconnects the transmission between the output shaft of the motor 3 and the connecting shaft 12. Through the design of the disconnection mechanism, the output shaft of the motor 3 can continue to rotate while the two vertical plates rotate as needed. The continuous rotation of the two vertical plates can prevent injury to workers and avoid frequent starting and stopping of the motor 3, which could cause damage. The rotating plate 26 is slidably connected in the rotating groove 27 by the locking beads 28, which can reduce the friction between the rotating plate 26 and the rotating groove 27. The design of at least three equally spaced locking beads 28 can ensure the stability of the rotating plate 26 during rotation.

[0034] The vertical shaft 5 has a cavity 19 inside, and a sliding rod 22 is slidably connected to the cavity 19 by a spring. The sliding rod 22 is rectangular, and its other end slidably connects through the cavity 19. A secondary shaft 21 is fixedly connected to one end of the sliding rod 22 inside the cavity 19. A rotating shaft 24 is slidably connected through the cavity 19. A main shaft 20 is fixedly connected to one end of the rotating shaft 24 inside the cavity 19. The main shaft 20 and the secondary shaft 21 mesh with each other through side teeth. Two connecting ropes 18 are rotatably connected to the surface of the rotating shaft 24.

[0035] The horizontal shaft 6 is divided into a fixed shaft 10 and a telescopic shaft 9. The telescopic shaft 9 is slidably connected to the telescopic shaft 9 by a spring. The other ends of the two connecting ropes 18 are respectively fixedly connected to the ends of the telescopic shaft 9. The surface of the rotating shaft 24 is fitted with a baffle 23. There are two baffles 23. The pair of baffles 23 are symmetrically distributed around the central axis of the sliding shaft. The connecting ropes 18 are located between the two baffles 23.

[0036] During operation, when cleaning beakers with smaller diameters, rotating the shaft 24 causes the connecting rope 18 to wind up, while simultaneously sliding the telescopic shafts 9 on both sides towards each other, reducing the distance between the two upright plates. The side teeth between the main shaft 20 and the auxiliary shaft 21 act as a limit to prevent the shaft 24 from reversing. The two baffles 23 prevent the connecting rope 18 from getting stuck between the main shaft 20 and the auxiliary shaft 21. The rectangular slide bar 22 ensures that it slides back and forth under the action of the spring without rotating. When the two upright plates need to be reset, sliding the slide bar 22 away from the upright shaft 5 releases the limit on the main shaft 20, and the two upright plates reset under the action of the spring.

[0037] The vertical shaft 5 has a slot 17 at its end, and a support strip 16 is fixedly connected to the surface of the vertical plate 7. The support strip 16 is slidably connected in the slot 17. During operation, the support strip 16 can support the "L"-shaped vertical plate to prevent deformation and reduce the cleaning effect.
