Embodiment Construction

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] refer to Figure 1-4 The nozzle 100 provided by the present invention includes a cylindrical threaded connection portion 10 and a spray head 20 formed at one end of the threaded connection portion 10 and having a diameter larger than the diameter of the threaded connection portion 10 . An abutment wall 29 is formed between the threaded connection portion 10 and the spray head 20 for resisting the axial loosening of the threaded connection between the threaded connection portion 10 and the external pipeline.

[0014] The threaded connection portion 10 is used to fix and seal the entire nozzle 100 with other devices for providing liquid, such as water pipes, in the form of threads, so as to spray and atomize the liquid through the nozzle 100 .

[0015] The inside of the threaded connection portion 10 is axially provided with a flow control hole 12 w...

Abstract

The invention relates to a spray nozzle which comprises a thread connection part and a spray head, wherein the spray head is larger than the diameter of the thread connection part, a flow control hole is axially formed in the thread connection part, an accumulated water bulk cavity which is communicated with the flow control hole and defined by an annular inner wall is further formed along the axial direction facing to the spray head in the thread connection part, the diameter of the accumulated water bulk cavity is larger than that of the flow control hole, the accumulated water bulk cavity is further connected with the flow control hole through a conical wall, and the accumulated water bulk cavity extends into the spray head; a conical surface which is convex to the accumulated water bulk cavity is formed in the spray head, a plurality of whirl holes which are communicated with the accumulated water bulk cavity and diffusion conical holes which are respectively communicated with each whirl hole and penetrate a circumferential outer wall of the spray head; and the conical surface extends to each whirl hole. As the spray nozzle uses the larger main flow control hole and comprises the whirl holes, the spray nozzle is less prone to being blocked. Simultaneously, a plurality of gaps are formed on the spray nozzle, the spray nozzle is easy to atomize liquid; in addition, the spray nozzle has simple structure and convenient manufacture.

Description

【Technical field】 [0001] The present invention relates to a nozzle, in particular to a nozzle with simple structure and not easy to be blocked. 【technical background】 [0002] Nozzle is a liquid atomization device commonly used in industrial production. At present, the nozzles on the market have various structural forms, which can be divided into different structural types such as hollow, solid, conical and fan-shaped. [0003] In the existing conical nozzles, the liquid flow angle is about 120 degrees, which requires the installation height of the nozzles. In addition, the flow control hole of the conical nozzle is small and easy to block. Thus affecting the normal use of the nozzle. At the same time, the existing nozzle structure is relatively complicated. [Content of the invention] [0004] The object of the present invention is to provide a nozzle with a simple structure and not easily clogged. [0005] To achieve this purpose, the present invention adopts the fol...
