AI Technical Summary

Problems solved by technology

So the service life is not long, so it is easy to clog and leak
In addition, some domestic imitation nozzles are worse than American patented products in terms of manufacturing process, technology and materials, so the exposure problem is even more serious

Embodiment Construction

[0010] The shower head of the present invention will be described in detail below in conjunction with the accompanying drawings;

[0011] In order to better understand the detailed working principle of the nozzle of the present invention, the working principle of the partial structure of the nozzle is explained first. The spray head of the present invention includes two compression chambers 5 and 6 , the first compression chamber 5 includes a wiper piston 9 , and the upper half of a cylinder body 14 . 2. The atomizing nozzle includes the position from the valve needle 10 to the atomizing nozzle. The second compression chamber 6 includes the lower part of the cylinder body 14, the small piston 12, the spring 13 and the liquid inlet hole at the bottom of the cylinder body 14, 4, the first valve device 2, including the valve needle 10, the atomizing nozzle 1 on the wiper piston 9 . The nozzle channel 8 includes a small piston 12 , a valve ball 11 and a valve needle 10 . The su...

Abstract

A hand-held compressing sprayer with floating piston for spraying insecticiding aerosol, liquid wax, or antirust agent features that the cylindrical surfaces of the both ends of its liquid scrapping ring has liquid scrapping lip, its cylinder body has the relative pressure releasing hole for returning the leakge liquid back to container, and said sprayer has also the first compression chamber and its atomizing nozzle, the second compression chamber, and the first valve unit.

Description

Technical field: [0001] The present invention relates to a spraying device, especially a hand-held floating device which is characterized by supplying liquid or other fluids and is widely used in insecticide aerosol, automotive liquid wax spray, tube spray paint, and mold antirust agent. Piston type compression spray barrel, Background technique: [0002] The nozzles in the prior art have poor sealing performance and are prone to leakage. It is more serious especially when the spray cylinder is lying down or upside down. Wherein typical structure sees U.S. patent VS-3399836, see accompanying drawing 1 for details, and its specific defect is as follows: when the nozzle is in the non-working state, the piston 15 goes up, and the wiper ring 16 on the piston 15 is always in a pressurized state. It will inevitably deform the wiper ring 16 after being pressed, shorten its life, and cause adhesion between the wiper ring 16 and the inner wall of the cylinder body 17. After the adh...
