Detailed Implementation

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an automatic cleaning mechanism for a viscometer, comprising a housing 1, a cleaning cylinder 2, and a cleaning nozzle 3, as shown below. Figure 1As shown, the outer shell 1 is cylindrical with an open top. The cleaning cylinder 2 is rotatably disposed inside the outer shell 1 and coaxially disposed with the outer shell 1. There are multiple cleaning nozzles 3, which extend in the same direction as the axis of the cleaning cylinder 2 and are disposed on the inner wall of the cleaning cylinder 2. The bottom of the outer shell 1 is provided with a drain pipe 4 that communicates with the cleaning cylinder 2. The side wall of the outer shell 1 is connected to a water injection pipe 5. The drain pipe 4 is connected to an external water tank and is equipped with a micro water pump inside. When the equipment is in use, the viscometer needle is inserted into the cleaning cylinder 2 from top to bottom. The micro water pump works, so that the cleaning water in the water tank is sprayed out through the cleaning nozzles 2 to clean the needle. The wastewater after cleaning is discharged through the drain pipe 4.

[0019] Specifically, the lower end of the cleaning cylinder 2 is rotatably connected to the inner wall of the outer shell 1, and the upper end of the cleaning cylinder 2 is fixedly connected to an annular sealing plate 6. The outer shell 1, the cleaning cylinder 2, and the annular sealing plate 6 constitute an annular cavity structure 7. The water injection pipe 5 is connected to the annular cavity structure 7. The annular sealing plate 6 and the side wall of the outer shell 1 are sealed, so that the annular sealing plate 6 can rotate relative to the outer shell 1 while maintaining the sealing of the annular cavity structure 7. After the cleaning water is injected into the interior of the annular cavity structure 7, it is sprayed out by the cleaning nozzle 3 under pressure. When the cleaning cylinder 2 rotates, it drives the cleaning nozzle 3 to rotate, ensuring the pressure of the cleaning water spray while ensuring thorough cleaning without dead corners and improving cleaning efficiency.

[0020] Specifically, such as Figure 1 As shown, a connecting pipe 8 is provided through the lower side wall of the cleaning cylinder 2, and the connecting pipe 8 is coaxially arranged with the cleaning cylinder 2. The drain pipe 4 passes through the lower side wall of the outer shell 1 and is rotatably connected to the connecting pipe 8. While the cleaning cylinder 2 rotates relative to the outer shell 1, the connection between the connecting pipe 8 and the drain pipe 4 is maintained, ensuring that sewage can be discharged in a timely manner through the drain pipe 4.

[0021] Specifically, the side wall of the cleaning cylinder 2 is provided with a strip-shaped through groove 9, such as... Figure 3 As shown, the extending direction of the strip-shaped channel 9 is the same as the axial length direction of the cleaning cylinder 2, and the strip-shaped movable block 10 is movably provided inside the strip-shaped channel 9, such as... Figure 1 As shown, the strip-shaped movable block 10 has a groove extending in the same direction on the side away from the axis of the cleaning cylinder 2. An elastic element, such as a spring, is provided between the strip-shaped movable block 10 and the strip-shaped through groove 9. Figure 3 As shown, the two sides of the strip-shaped movable block 10 are provided with strip plates extending in the same direction. A guide rod is fixed to the side wall of the cleaning cylinder 2 at the corresponding strip plate. The guide rod passes through the end face of the strip plate and is movably connected to the strip plate. A spring is sleeved on the outside of the guide rod, causing the strip-shaped movable block 10 to tend to move away from the axis of the cleaning cylinder 2. The cleaning nozzle 3 passes through the end face of the strip-shaped movable block 10. An annular sealing block 11 is fixedly connected to the inner wall of the annular cavity structure 7. Figure 1As shown, under normal conditions, the cleaning nozzle 3 contacts the annular sealing block 11 to achieve a seal under the action of the elastic element. The water injection pipe 5 is located inside the outer shell 1. When water is injected, due to the seal of the cleaning nozzle 3, the water injection pipe 5 will fill the interior of the annular cavity structure 7 under pressure. Then the pressure gradually increases, causing the strip-shaped movable block 10 to overcome the elastic element and move towards the axis of the cleaning cylinder 2, so that the cleaning nozzle 3 separates from the annular sealing block 11. The cleaning water inside the annular cavity structure 7 can then be sprayed out through the cleaning nozzle 3, ensuring the water flow pressure and ensuring that the cleaning water fills the annular cavity structure 7 before being sprayed out by the cleaning nozzle 3 to achieve cleaning. Therefore, the cleaning effect is better.

[0022] Specifically, such as Figure 1 As shown, a drive housing 12 is fixedly connected to the bottom of the outer shell 1. An annular groove 13 is coaxially provided on the lower side wall of the cleaning cylinder 2. The inner wall of the annular groove 13 is provided with teeth. A drive motor 14 is provided inside the drive housing 12. The drive motor 14 is connected to a gear 15 that meshes with the teeth. The drive motor 14 drives the gear 15 to rotate, and controls the rotation of the cleaning cylinder 2 under the action of the teeth. A switch for controlling the drive motor 14 and the micro water pump can be provided on the outside of the drive housing 12.

[0023] When using this invention, the viscometer needle is inserted into the cleaning cylinder 2 from top to bottom. The micro water pump injects cleaning water from the water tank into the annular cavity structure 7 through the water injection pipe 5. Under pressure, the strip-shaped movable block 10 moves against the elastic element, and the cleaning nozzle 3 separates from the annular sealing block 11. The cleaning water inside the annular cavity structure 7 is sprayed out by the cleaning nozzle 3. The drive motor 14 drives the gear 15 to rotate, which in turn drives the cleaning cylinder 2 to rotate, causing the cleaning nozzle 3 to rotate synchronously, thus cleaning the needle inserted into the cleaning cylinder 2, resulting in a better cleaning effect.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
