Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In a first embodiment, as shown in fig. 1 to 6, the present invention provides a nozzle including: the water inlet pipe 1-1, the cap 2-1 and the core body 3-1, wherein the water inlet pipe 1-1 is used for conveying water; the cap 2-1 is provided with a water spraying hole 2-2; the outer peripheral wall of the core body 3-1 is provided with a spiral groove 3-2; wherein, the cap 2-1 is arranged on a pipe orifice of the water inlet pipe 1-1, the core body 3-1 is rotatably arranged in the water inlet pipe 1-1, and the cap 2-1 covers the core body 3-1.

Specifically, in the actual use process, water is conveyed to the core 3-1 through the water inlet pipe 1-1, and the water flow applies impact force to the core 3-1 in the direction towards the cap 2-1 on one hand, and on the other hand, the water flow flows through the spiral groove 3-2 to drive the core 3-1 to rotate. The rotating core body 3-1 influences water sprayed from the water spraying holes 2-2, and the posture of the water sprayed from the water spraying holes 2-2 is changed periodically under the condition that the water inlet pressure is unchanged, so that the cleaning range is effectively enlarged, the cleaning efficiency is improved, and the cleaning effect is optimized.

Preferably, the inner wall of the cap 2-1 is provided with a convex structure 2-3, one end face of the core body 3-1 is provided with a spiral face 3-3, and the convex structure 2-3 is positioned above the spiral face 3-3 and is used for abutting against the spiral face 3-3 after water enters the water inlet pipe 1-1

The core body 3-1 enables the spiral surface 3-3 to be always abutted against the convex structures 2-3 under the impact action of water flow. While as the core 3-1 rotates, the helicoid 3-3 will also rotate relative to the raised structure 2-3, and the core 3-1 will in turn move relative to the cap 2-1 via the action of the helicoid 3-3 to move the core 3-1 closer to and further away from the cap 2-1. In the process that the core body 3-1 is close to and far away from the cap 2-1, the posture of water sprayed from the water spraying holes 2-2 is changed alternately, so that under the condition that the water pressure is not changed, the coverage range of the water sprayed by the spray head is larger, an impact type water spraying effect can be realized, the cleaning efficiency is improved, and the cleaning effect is optimized.

In order to enable the core body 3-1 to stably rotate in the water inlet pipe 1-1, a plurality of spiral grooves 3-2 are uniformly distributed on the outer peripheral wall of the core body 3-1, and the spiral grooves 3-2 apply balanced torsional force to the core body 3-1 in the flowing process of water, so that the core body 3-1 can stably rotate.

In addition, as for the outer configuration of the core 3-1, various configurations can be adopted. For example: the core body 3-1 is integrally in a conical structure, and the head of the conical structure is inserted into the water inlet pipe 1-1. Alternatively, the core 3-1 has a trapezoidal cross section along its axis, the core 3-1 has a first end face and a second end face, the first end face has a diameter larger than that of the second end face, and the helicoid 3-3 is formed on the first end face.
