Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spraying device used for automatically cleaning and drying articles by spraying cleaning liquid, air, etc. onto them.

Conventionally, when cleaning or drying is automatically performed by spraying cleaning liquid or air onto the surface of an item, in order to spray the cleaning liquid or air evenly over a certain area, it is necessary to point the nozzle of the spraying device at the item. It had the disadvantage of requiring a complicated drive mechanism to move and swing automatically.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the above-mentioned drawbacks and to provide a spraying device that has a simple structure and can perform cleaning and drying evenly and efficiently.

Hereinafter, one embodiment of the present invention will be described in detail based on the accompanying drawings.

The enlarged diameter part 3 at the rear end of the nozzle 2, which has an air outlet 1 formed at its tip, is fitted onto the tip of a flexible short hose 4 made of rubber or the like, and the base end of the hose 4 is The nozzle 2 is connected via a connector 7 to a discharge port 6 provided on the lower surface of a horizontally piped pneumatic feed pipe 5 connected to an air compressor (not shown).
It is hung with the head facing downward and swinging freely. A frame 10 formed into a rectangle by bending a round bar is fixed to a mounting ring 8 via hanging arms 9 fixed to both longitudinal ends of the frame 10. The frame body 10 is fixed parallel to the pneumatic feed pipe 5 by fitting the frame body 10 to the outer periphery of the discharge port 6 and tightening the mounting screw 12. 4a
is passing through.

A hose 4 through which compressed air, which is fed to the air pressure feed pipe 5 by starting the air compressor, is communicated with the air compressor.
When the nozzle 2 is sprayed from the spout 1 of the nozzle 2 onto the surface of the material to be dried placed directly below it, the nozzle 2 receives a reaction force and tries to move upward, but the hose 4 Due to its flexibility, the nozzle 2 is bent and tilted, and in response to the resulting horizontal component force, the hose 4 swings its head sharply in one direction, as shown by the chain line in FIG. The tip portion 4a hits the frame 10. Then, the hose 4 bends due to the jetting reaction force of the compressed air, the nozzle 2 swings in the opposite direction, and the tip 4a of the hose 4 touches the frame 10.
As this movement is repeated, the nozzle 2 generates a violent swinging motion in all directions, and the compressed air ejected from the outlet 1 is evenly blown onto the surface of the material to be dried, drying it. will be carried out. In addition, since the tip 4a of the hose 4 hits the frame 10 and the swing angle is regulated within a certain range, spraying in unnecessary directions toward the surface of the material to be dried is prevented, and the frame body 1
0 can adopt any shape depending on the spraying range, such as circular or square, and the frame 10
By moving the installation position of hose 4 up and down,
The swing range can be adjusted.

The spraying device of the present invention can also be applied to a cleaning device that sprays cleaning liquid onto the surface of an article by supplying the cleaning liquid to a nozzle using a liquid pressure pump.

As clarified in the above explanation, the spraying device of the present invention has a nozzle with a spout formed at the tip that is fitted onto the tip of a flexible hose, and the base end of the hose is connected to air or water. The nozzle is connected to the discharge port of a pressure-feeding pipe connected to a pressure-feeding source of fluid, such as a fluid, so that the nozzle oscillates due to the reaction force of the fluid. The gist of this system is that a frame is provided to restrict the range of swing movement, and the nozzle automatically swings due to the reaction force generated by the ejection of fluid such as compressed air. Since the swinging angle is regulated within a certain range by the frame, unnecessary swinging movements are prevented and items can be washed and dried evenly.
It is efficient and does not require any complicated mechanism or drive source for swinging the nozzle, resulting in an extremely simple structure.
