All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In a first embodiment, as shown in fig. 1 to 6, the present invention provides a spray head, 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 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, during actual use, water is delivered to the core 3-1 through the water inlet pipe 1-1, and the water flow applies an impact force to the core 3-1 toward the cap 2-1 on one hand, and flows through the spiral groove 3-2 to drive the core 3-1 to rotate on the other hand. The rotating core body 3-1 will affect the water sprayed from the water spraying hole 2-2, so that the posture of the water sprayed from the water spraying hole 2-2 is periodically changed under the condition of unchanged water inlet pressure, 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 protruding structure 2-3, one end face of the core 3-1 is provided with a spiral face 3-3, and the protruding structure 2-3 is positioned above the spiral face 3-3 and is used for abutting against the spiral face 3-3 after the water inlet pipe 1-1 is filled with water

Under the impact of water flow, the core body 3-1 enables the spiral surface 3-3 to be always abutted against the protruding structure 2-3. With the rotation of the core 3-1, 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 helicoid 3-3, so that the core 3-1 approaches and moves 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 postures of the water sprayed from the water spraying holes 2-2 are changed alternately, so that the coverage range of the water sprayed from the spray head is larger under the condition that the water pressure is unchanged, the impact type water spraying effect can be realized, and further the cleaning efficiency is improved and the cleaning effect is optimized.

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