Description

Rotary spray structure

The present invention relates to a rotary spray structure, and more particularly to a rotary spray structure that uses a gas flow to rotate a rotary spray element to rotate a liquid.

In daily life, when cleaning a large surface such as a car shell, a glass window or a wall surface, the cleaning agent is usually sprayed on the surface to be cleaned, and then brushed and the like. In order to effectively improve the range of detergent spraying, a rotary spray device has been introduced in the past, mainly by rotating the rotating tube in the body of the device, and then rotating the rotating tube by using the air flow. The liquid is then sprayed rotatably.

As described above, in order to allow the liquid to be sprayed out rotatably, the rotating tube must be rotatably disposed in the device, and the rotating tube and the outer sleeve must be in a relatively rotating state, so that a bearing or the like needs to be disposed therebetween.
