Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cleaning, and relates to the inside and outside cleaning of a spray gun, in particular to a cleaning device and a spray gun cleaning device. BACKGROUND

[0002] In the field of automobile repair and painting, paint sprayed by a spray gun can achieve a uniform and smooth coating.

[0003] The paint spray guns used in automobile painting mainly have the following types:

[0004] 1. Gravity feed spray gun: The paint cup of the gravity feed spray gun is located at the top of the spray gun, and the paint flows into the nozzle under the action of gravity. This type of spray gun is suitable for spraying paint with low viscosity, and the spraying is uniform.

[0005] 2. Suction spray gun: The paint cup of the suction spray gun is located at the bottom of the spray gun, and the paint flows into the nozzle by suction. It is suitable for large-area spraying and high-viscosity paint.

[0006] No matter which of the above spray guns needs to be thoroughly cleaned after use to ensure that there is no paint residue; regularly check the nozzle and remove any blockages to ensure the spraying effect. Especially in the process of painting or painting, it is often necessary to change the paint. In order to prevent residual paint or residual paint from remaining in the spray gun, the spray gun needs to be cleaned before changing the paint.

[0007] For example, Chinese patent document 200880010417.9 discloses a cleaning device for cleaning a spray gun (S), especially a paint spray gun, which has at least one cleaning nozzle (1) connected to a delivery device (2) for a washing liquid, and a friction cleaner (3) for manually cleaning the spray gun or a spray gun part. Such a known cleaning device can only inadequately clean the spraying channel. The purpose of the present invention is to provide a cleaning device with which both the outer surface parts and the spraying channel can be effectively and environmentally friendly cleaned, which is achieved by arranging the cleaning nozzle (1) in the vicinity and above the friction cleaner (3), so that the washing liquid is sprayed through the cleaning nozzle (1) into and / or onto the spray gun (S), while the spray gun (S), especially the spray gun nozzle, can be manually cleaned by friction with the friction cleaner (3).

[0008] In the above technical solution, although both flushing cleaning inside the spray gun and rubbing cleaning outside the spray gun are provided, the water flow through the spray gun is exposed to the outside space, which is easy to cause irregular splashing, resulting in environmental pollution and being difficult to collect, reducing the operation experience of workers. On the other hand, due to the lack of collection and flow guiding effect, the scattered waste liquid cannot be reused, thereby causing water flow waste. In addition, the rubbing cleaner needs to be fully wetted to improve the rubbing cleaning effect, thereby increasing the process and reducing the cleaning efficiency.

[0009] Furthermore, in the above technical solution, the selection switch and the operation knob are used to control the two gas paths of the cleaning spray gun and the drying, resulting in a large number of gas paths, a complex connection structure, increased installation difficulty and inconvenience for subsequent maintenance.
