Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners for coating machines, in particular to a vacuum cleaner for coating machines. Background Art

[0002] After a period of time in the coating machine, excess plating material and dust will accumulate in the working room and lining. These impurities will not only affect the quality of the coating, but may also cause the equipment's exhaust speed to slow down. Therefore, a vacuum cleaner is needed to effectively remove these dust and impurities to keep the working room clean.

[0003] The coating machine needs to be cleaned regularly with a vacuum cleaner during operation to ensure uniformity and density of the film layer during the coating process, improve the quality and performance of the coated product, and extend the service life of the equipment. Cleaning and maintenance can reduce equipment failures and maintenance costs caused by impurity accumulation. The vacuum cleaner can also help clean hard-to-reach areas, such as the vacuum chamber and liner.

[0004] During use, it is not convenient to quickly replace the vacuum cleaner head, which affects the stability during use. When the vacuum cleaner head is adjusted in multiple positions and the vacuum tube is twisted, it is very easy to cause the vacuum cleaner head to fall off;

[0005] In order to overcome the above-mentioned drawbacks, the prior art (Chinese patent application number CN200710150102.1, application date 2007-11-07) discloses a novel vacuum cleaner nozzle structure, which can freely change the size of the nozzle opening according to the size of the area to be vacuumed and cleaned, eliminating the need to frequently plug and unplug nozzles of different shapes, thereby bringing great convenience to users.

[0006] Although the existing technology can complete the connection of the vacuum nozzle, during operation, the vacuum nozzle is not convenient to follow the twisting of the vacuum tube to form a nested rotation, which easily causes the vacuum nozzle to need to adjust the moving direction of the vacuum tube in some positions, affecting the vacuum cleaning efficiency;

[0007] In view of the above problems, it is urgent to carry out innovative design based on the original coating machine vacuum cleaner. Utility Model Content

[0014] Through the above structure, it is convenient to stably rotate and engage the locking assembly on the outside of the connecting pipe during use, preventing jamming between the connecting pipe and the locking assembly in use, making it convenient for the two to form a nested rotation for use, and improving the stability of the vacuum cleaner head assembled with the connecting pipe.

[0015] Preferably, the angle ring and the locking assembly form a nested rotating structure, and the angle ring and the handle form an integrated structure, and the angle ring and the locking assembly form a positioning sliding structure through the slide groove and the positioning block, and the positioning block and the inner surface of the locking assembly are embedded and installed.

[0016] Through the above structure, the stability of the angle ring can be effectively controlled during use, which facilitates the coordinated use of the angle ring and the positioning block.

[0017] Preferably, the positioning block forms an elastic structure with the upper side of the angle ring through a tension spring, and the angle ring, the clamp and the ratchet form an integrated structure, and the clamp and the ratchet are arranged at equal angles with respect to the center axis of the outer surface of the angle ring.

[0018] Through the above structure, elastic sliding can be effectively formed during use, and when disassembled later, the angle ring can be automatically reset for use through elastic formation.

After the locking assembly and the positioning assembly are engaged and assembled, the vacuum head assembled with the connecting tube is controlled to rotate at multiple angles during operation, thereby preventing the vacuum tube from twisting, which would affect the stability and convenience of the vacuum head. The engagement of the locking assembly and the positioning assembly can also improve the stability of the vacuum head during operation.

[0025] 2. The vacuum cleaner of the coating machine is provided with an angled structure on the end of the outer surface of the vacuum head, and cooperates with the angle ring assembled with the connecting pipe, as well as the cooperation between the clamp installed on the angle ring and the ratchet.
