Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically to a cleaning structure for a vacuum cleaner. Background Technology
[0002] Hydrocarbon vacuum cleaners clean based on the dissolving power of the cleaning agent. Based on the degreasing mechanism of the solubility of grease or oily contaminants: the principle of like dissolves like, hydrocarbon cleaning agents have good environmental protection properties and cleaning ability, do not corrode metals, and can meet the cleaning needs of parts in many fields. They are often used in industry for cleaning mechanical components.
[0003] The typical cleaning structure of a hydrocarbon vacuum cleaner simply involves placing the workpiece into the cleaning chamber and relying on a spray mechanism in conjunction with vacuum to perform spray immersion cleaning. If necessary, auxiliary cleaning methods such as ultrasonic cleaning may also be added. Although these cleaning methods can improve the cleaning efficiency of the workpiece to some extent, the workpieces tend to pile up in the cleaning chamber, making it difficult to clean stubborn oil stains and dirt from the parts of the workpieces that come into contact with each other or from the parts of the workpieces that come into contact with the inner wall of the cleaning chamber and are far from the spray mechanism. This creates certain cleaning dead zones, which greatly prolongs the cleaning time and reduces the cleaning effect and efficiency. Utility Model Content
[0004] In view of this, the present invention provides a cleaning structure for a vacuum cleaner, which can rotate the material to be cleaned in the cleaning chamber, thereby enabling more efficient cleaning of all parts of the workpiece, resulting in better cleaning effect and higher efficiency.
[0005] To solve the above-mentioned technical problems, this utility model provides a cleaning structure for a vacuum cleaner, including a cleaning chamber horizontally mounted on a frame. The cleaning chamber is welded to the frame, and a cleaning basket is detachably mounted inside a fixed frame. The cleaning basket is secured within the fixed frame and can slide along the axis of the cleaning chamber under external force, enabling the installation and separation of the cleaning basket from the fixed frame. A rotating component is provided on the cleaning chamber, which can swing or rotate the fixed frame and the cleaning basket inside the fixed frame. This utility model can drive the fixed frame to rotate while simultaneously rotating the cleaning basket and the workpiece inside it. Combined with the cleaning agent in the cleaning chamber, it achieves efficient rinsing of the workpiece, greatly reducing cleaning dead zones, increasing the oscillation frequency of the cleaning liquid in the cleaning chamber, improving cleaning efficiency, and making the cleaning more efficient and thorough.
[0006] Annular rails are welded to both ends of the cleaning chamber, with the openings of the annular rails facing the axis of the cleaning chamber.

There are two water seals, which are respectively mounted on the rotating shaft on both sides of the side wall of the cleaning chamber. The water seals are used to efficiently seal the connection between the cleaning chamber and the rotating shaft without affecting the rotation of the rotating shaft, which greatly improves the sealing performance of the cleaning chamber. The fixed frame is fixed together with the rotating shaft. This invention can rotate the rotating shaft and the fixed frame together by rotating the output shaft of the drive component, thereby realizing the throwing of the workpiece to be cleaned inside the fixed frame and the tumbling and stirring of the cleaning liquid in the cleaning chamber, which greatly improves the cleaning efficiency and effect of the workpiece to be cleaned.
[0008] A speed reducer is provided at the end of the output shaft of the servo motor. The output end of the speed reducer is fixed together with the rotating shaft. The rotating shaft passes through the inner ring of the sealed bearing and is fixed together with the inner ring of the sealed bearing.

The telescopic push rod is an electric push rod or a hydraulic push rod. A sealing door is provided at the end of the output rod of the telescopic push rod. A sealing gasket is provided on the surface of the sealing door opposite to the cleaning chamber. The sealing gasket is made of non-slip, wear-resistant and corrosion-resistant rubber. The sealing door seals the front end of the cleaning chamber under the push of the output rod of the telescopic push rod.
[0010] The mounting bracket is also equipped with a slide rail, and a slider is slidably installed inside the slide rail. The slider is fixed to the outside of the sealed door.

[0028] How to use this utility model:
[0029] First, it needs to be clarified that the cleaning structure involved in this utility model is mainly used in the cleaning chamber 200 of a horizontal hydrocarbon vacuum cleaner. Working in conjunction with the cleaning fluid within the cleaning chamber 200, it achieves efficient cleaning of the workpiece. This utility model uses the automated cleaning and rinsing of components in the lubricating oil system of an aircraft engine and casing-type parts as an example to remove hardened skin, carbon deposits, oil, grease, debris, and other impurities from the surface of the components. The usage of the cleaning structure is described in detail below. When cleaning is required, the cleaning basket containing the workpiece is conveyed into the fixed frame 400 within the cleaning chamber 200. Then, the output rod of the telescopic push rod 600 is activated. The sealing door 700 is pushed to close the cleaning chamber 200. Then, the water pump is started to draw the cleaning solvent from the cleaning agent storage tank into the cleaning chamber 200. After reaching the appropriate water level, the output shaft of the servo motor is started to rotate. The rotation of the output shaft of the servo motor is reduced by the reducer 303 and then transmitted to the rotating shaft 302. The rotating shaft 302 and the fixed frame 400 rotate in the cleaning chamber 200. With the spraying of the cleaning machine's spray system and the cooperation of the ultrasonic cleaning system, the workpiece is rinsed efficiently, greatly reducing cleaning dead corners, increasing the oscillation frequency of the cleaning liquid in the cleaning chamber 200, improving cleaning efficiency, and making the cleaning more efficient and thorough.
