Problems solved by technology

[0005] In addition, the existing nozzles only simply combine liquid nozzles and air nozzles, which are prone to air and liquid leakage problems, or are integrally formed, resulting in complex and difficult post-maintenance
And the existing design is prone to the problem of liquid backflow to the airway

Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing:

[0027] like Figure 1-3 As shown, the present invention consists of a liquid cap 100 and an air cap 200 . One end of the liquid cap 100 protrudes outward to form a connecting portion 1001 , and the other end shrinks toward the center. The liquid cap 100 is a middle-pass structure, and its inside is a liquid cavity 101, and one end of the liquid cavity 101 shrinks inwardly and is the same end as the aforementioned contracting end, and the end portion is a water spray cavity 1002; There are axial through holes as air inlets.

[0028] The air cap 200 has a concave structure, and a nozzle 205 is opened at the bottom of the concave part, and a bump 204 is formed around the nozzle 205 .

[0029] The liquid cap 100 is connected with the air cap 200 through the connection part 1001. After the two are connected, a space is formed between the two as the air cavity 120, and the air...

Abstract

The invention discloses an external mixing type atomization nozzle. The external mixing type atomization nozzle comprises a liquid cap and an air cap, wherein one end of the liquid cap extends outwards to form a connecting part; the connecting part is provided with a through air inlet; a hollow part of the liquid cap is a liquid cavity; one end of the liquid cavity is a water spraying cavity; theair cap is of an internal concave structure; a nozzle is arranged at the bottom of the internal concave structure; a bump is formed around the nozzle in a convex manner; the connecting part is connected to a port part of the air cap; an air cavity is formed between the liquid cap and the air cap; the air cavity is divided into a first air cavity and a second air cavity through the bump; one end ofthe first air cavity communicates with the water spraying cavity; and air injection holes are formed in one end of the second air cavity. The external mixing type atomization nozzle has the beneficial effects that the structure is simplified, simple disassembly and cleaning maintenance of the nozzle are achieved, the problems that air and a liquid leak and the liquid flows back to an air channelare solved, and besides, even though the liquid flows back, the liquid can be well cleaned through the design.

Description

technical field [0001] The invention belongs to the field of water spray devices, in particular to a spray head. Background technique [0002] Indoor breeding places such as greenhouses and vegetable greenhouses need spraying for disinfection, air humidification, spraying of pesticides and fertilizers, industrial dust removal, cooling of pedestrian streets, and even indoor spaces with special requirements to use spraying to adjust humidity. In order to spray uniformly and improve the spray efficiency, the pipelines for conveying pressure water, fertilizer and medicine are usually arranged in the spray space, and the spray nozzles installed on the outer wall of the pipeline are used for spraying. [0003] Some existing nozzles are welded, which has poor adaptability and is difficult to replace. [0004] In addition, most of the existing nozzles can achieve large-area spraying function. Most of the existing technologies use a combination of a single air channel and a liquid p...
