Abstract
The invention discloses a spray nozzle. The spray nozzle comprises a nozzle body, one end of the nozzle body is provided with a water inlet, and the other end of the nozzle body is provided with a nozzle head. The nozzle head is provided with a strip water orifice, and the side wall of the nozzle body is obliquely provided with more than three water spray passages. Owing to the more than three water spray passages obliquely formed in the side wall of the nozzle body, tap water spray direction is not perpendicular to the side wall of a barrel but inclined towards the side wall of the barrel to generate a rotating action force applied to the side wall of the barrel, so that the barrel is enabled to rotate by 360 degrees, all corners of the side wall of the barrel can be cleaned, and cleaning effects are excellent. By the aid of the strip orifice of the nozzle head, the tap water can be ejected towards the bottom of the barrel through the strip orifice to clean the bottom of the barrel, and each corner of the bottom of the barrel can be cleaned by the tap water through the strip orifice due to 360-degree rotation of the barrel during cleaning. Therefore, by the aid of the spray nozzle, all corners of the side wall of the barrel and the bottom of the barrel can be well cleaned, and effectiveness in cleaning is achieved. In addition, the spray nozzle is extremely simple and extremely low in cost.
Description
Technical field
The present invention relates to the cleaning technique field of bucket, especially relate to a kind of nozzle and cleaning device.
Background technology
Tradition often takes manual type to the cleaning of bucket, and its operating efficiency is extremely low, and consumption consuming time is artificial.Especially for the bucket of smallmouth, such as: GPB, GPB is often used for filling Drinking Water, and it is high to purity requirements in bucket.Because the bucket nose of GPB is less, workman is difficult to directly be tucked in bucket and to each face of bucket through bucket nose by cleaning part clean.
And feasible mode has, utilize water pipe to be tucked in bucket through bucket nose, control the hydraulic pressure size of water pipe, water pipe is rinsed each face in bucket.Although it is better to the developing result at bucket top, each corner for sidewall cannot be cleaned completely, and cleaning efficiency is extremely low.Therefore, its cleaning performance is often difficult to meet the high request of people to cleanliness factor in bucket.
Summary of the invention
Based on this, the invention reside in the defect overcoming prior art, provide that a kind of cleaning performance is good, structure is simple and can improve nozzle and the cleaning device of cleaning efficiency.
Its technical scheme is as follows: a kind of nozzle, comprise nozzle body, described nozzle body one end is provided with water inlet, and the described nozzle body other end is provided with nozzle head, described nozzle head is provided with the water jet of bar shaped, and described nozzle body sidewall slope is provided with more than three passages of spraying water.
A kind of cleaning device of the present invention, comprise cleaning device body, described cleaning device body being provided with water supply line, being provided with nozzle for loading in the installing port of bucket nose, described installing port, and described water supply line is connected with the water inlet of described nozzle body.
Wherein in an embodiment, described nozzle body comprises the pipeline be communicated with described nozzle head, and described water spray passage is evenly distributed on described pipeline.
Wherein in an embodiment, described nozzle head is hemispherical or half elliptic or taper.
Wherein in an embodiment, described water jet is arranged on the middle part of described nozzle head.
Wherein in an embodiment, described water spray passage has three, and three described water spray passages are inclined on described pipe side wall all in the same direction, and the angle of spraying water described in arbitrary neighborhood between passage side is all identical.
