[0041] Please refer to Figures 1-4.

[0042] A cleaning device for cylindrical products includes:

[0043] Protective cover 1 is used to form internal airflow circulation and reduce dust leakage. Protective cover 1 is cylindrical in shape.

[0044] Fixing plate 2 is used to connect the structure. Fixing plate 2 is fixedly installed on the top of the protective cover 1.

[0045] Inlet pipe 3 is used to guide high-pressure gas, and inlet pipe 3 is installed through the inside of fixed plate 2;

[0046] Multiple negative pressure pipes 4 are used in conjunction with a negative pressure device to extract gas from the inside of the protective cover 1. The multiple negative pressure pipes 4 are installed inside the fixed plate 2.

[0047] The central ventilation shaft 8 is used to guide gas. The interior of the central ventilation shaft 8 is hollow. The central ventilation shaft 8 is installed through the interior of the fixed plate 2 and extends into the interior of the air inlet pipe 3.

[0048] Two bearings 6 are located on the outside of the central ventilation shaft 8;

[0049] The outer rotating seat 5 is located on the outside of the two bearings 6, and the outer rotating seat 5 is located at the bottom of the fixed plate 2;

[0050] The air-tight slip ring 7 is used for sealing connection. The air-tight slip ring 7 is set between the central vent shaft 8 and the outer rotating seat 5.

[0051] Two horizontal arms 9 are used to connect and guide the airflow, and the two horizontal arms 9 are set on both sides of the outer rotating seat 5;

[0052] Two corner connectors 10 are used to connect the structure and guide the airflow. The two corner connectors 10 are movably sleeved on the outside of the two horizontal arms 9.

[0053] Two vertical connecting shafts 11 are used to guide airflow, and the two vertical connecting shafts 11 are movably installed inside the two corner connectors 10;

[0054] Multiple cleaning nozzles 12 are used to blow out high-pressure airflow, and the multiple cleaning nozzles 12 are threadedly installed inside two vertical connecting shafts 11;

[0055] Support plate 17 and cleaning component 16 are provided for supporting cleaning component 16. Support plate 17 is provided at the bottom of protective cover 1.

[0056] Also includes:

[0057] The air guide hole is used to guide the airflow, and the air guide hole is set through the interior of the outer rotating seat 5;

[0058] Connector 15 is used to block the bottom end of the air guide hole, and connector 15 is threaded into the inside of the air guide hole;

[0059] The central shaft 13 is used to guide airflow and is threaded into the interior of the connecting seat 15.

[0060] Multiple rotating nozzles 14 are used to eject airflow, and the multiple rotating nozzles 14 are fixedly mounted on the outside of the central shaft 13;

[0061] Specifically, the device has two usage methods:

[0062] 1. When cleaning the outer wall of the product in 360 degrees, first place the mechanical parts on the support plate 17, then twist the central shaft 13 to remove the central shaft 13 from the inside of the connecting seat 15. Then, control the external drive component to move the protective cover 1 down. The protective cover 1 gradually fits onto the support plate 17. Then, the air inlet pipe 3 applies high-pressure gas. The high-pressure gas passes through the air inlet pipe 3, the central air shaft 8, the horizontal arm 9, the corner connector 10 and the vertical connecting shaft 11, and finally enters the cleaning nozzle 12. Part of the high-pressure airflow is discharged through the jet hole, generating a reverse thrust, which causes the external rotating seat 5 to drive the vertical connecting shaft 11 to rotate, which in turn drives the cleaning nozzle 12 to rotate, thus completing the cleaning process and achieving the effect of cleaning the outside of the mechanical parts.

[0063] 2. When the product is ring-shaped, the surfaces that need to be cleaned become the inner and outer sides. In this case, the mechanical parts need to be placed on the support plate 17 first, then the connecting seat 15 is twisted off, and then the central shaft 13 is threaded to the inside of the external rotating seat 5. At this time, the air guide hole will allow high-pressure airflow to enter the interior of the central shaft 13, and then this part of the high-pressure airflow is guided to the interior of the rotating nozzle 14, thus achieving the effect of spraying high-pressure airflow from the inside to the outside. Under the drive of the external rotating seat 5, it can rotate, which can complete the cleaning effect of the inner side of the mechanical parts. The cleaning process on the outside is the same as the principle in Scheme 1 above, which can simultaneously achieve the cleaning effect of the inner and outer sides of the mechanical parts.

[0064] It can achieve the effect of cleaning cylindrical mechanical parts of different shapes;

[0065] In the embodiment: both the outer rotating seat 5 and the connecting seat 15 have threaded holes inside, and the inner diameters of the two threaded holes are the same;

[0066] Specifically, the outer rotating seat 5 and the connecting seat 15 serve as a connecting structure. When the central shaft 13 is not needed, the central shaft 13 can be twisted to remove the interior of the connecting seat 15.

[0067] In the embodiment: the length of the two horizontal arms 9 is adjustable or customizable according to usage requirements, and is used to clean the outer surface of mechanical parts of different diameters;

[0068] Specifically, the lengths of the two horizontal arms 9 can be customized according to requirements, and can be used to clean mechanical parts of different diameters. They can be changed according to actual needs.

[0069] In the embodiment: air guide cavities are provided inside the external rotating seat 5, the horizontal arm, the vertical connecting shaft 11 and the central shaft 13, and multiple air guide cavities are connected together;

[0070] Specifically, the outer rotating seat 5, the horizontal arm 9, the vertical connecting shaft 11 and the central shaft 13 are provided with air guiding chambers. High-pressure gas can enter the air guiding chambers through the central ventilation shaft 8 to achieve the effect of guiding airflow.

[0071] In the embodiment, it also includes:

[0072] A drive assembly is used to drive the protective cover 1 to move up and down. The output end of the drive assembly is fixedly installed with the protective cover 1. The drive assembly is an existing structure and can be driven by either pneumatic or electric drive.

[0073] Specifically, the drive component is used to move the protective cover 1 up and down, thereby achieving the effect of moving the protective cover 1 up and down, which can conveniently cover the cleaning part 16. It can be driven by either pneumatic or electric drive, and the choice can be made according to the actual situation.

[0074] In the embodiment, it also includes:

[0075] Two jet holes are used to drive the cleaning structure to rotate. The two jet holes are respectively opened on the outside of the two corner connectors 10, and the two jet holes are respectively set on the opposite side of the two corner connectors 10.

[0076] Specifically, the jet holes are designed to generate a counterforce, allowing the outer rotating seat 5 to rotate outside the bearing 6 and the central ventilation shaft 8, thereby increasing the cleaning range.

[0077] Working principle: When it is necessary to clean the outside of the mechanical parts, unscrew the central shaft 13 and cover the outside of the mechanical parts with the protective cover 1. The high-pressure airflow enters the air inlet pipe 3, the central ventilation shaft 8, the horizontal arm 9, the corner connector 10 and the vertical connecting shaft 11. The setting of the jet hole can drive the external rotating seat 5 to rotate. The high-pressure airflow is sprayed out through the cleaning nozzle 12 to clean the outside of the mechanical parts. When cleaning the inside and outside of the mechanical parts at the same time, remove the connecting seat 15 and connect the central shaft 13 to the bottom of the external rotating seat 5. When the high-pressure airflow is turned on, the central shaft 13 rotates with the external rotating seat 5 to achieve the effect of rotating and cleaning the inside of the mechanical parts. Two different cleaning methods can be achieved, and the outer surface of the mechanical parts can be cleaned from all directions.

[0078] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
