The narrowing section is gradually narrowed from large at the lower part to small at the upper part so as to be matched with the size of a water inlet hole at the lower part, and gradually guides water flow to enter the vertical section, and the water flow is upwards rushed to the top end of the first inner cavity and then turns downwards to enter the second inner cavity.
As a further improvement of the above technical solution, the cavity wall below the second inner cavity is obliquely transited to the water outlet. The inclined cavity wall is arranged below the water guide pipe, so that smooth flow guide is facilitated, and the condition that water flow is disordered due to the fact that water flow directly impacts a component structure is avoided.
As a further improvement of the above technical solution, the outer tube further comprises a sleeved section, the lower part of the sleeved section is connected with the upper part of the expansion section, and the sleeved section is tightly sleeved on the periphery of the upper section of the inner tube. The coupling relation of outer tube and inner tube can be strengthened to the section of cup jointing, makes two pipe fittings be difficult for pine take off, maintains the position stability of inflation section.
As a further improvement of the above technical solution, a lower portion of the expansion section radially contracts to hoop an outer periphery of a lower section of the inner pipe. Therefore, the expansion section naturally forms an annular space, the water flow basically only flows out of the water outlet holes, the direction of the water flow can be kept stable, and a piece of turbulent flow is prevented from being formed outwards.
As a further improvement of the technical scheme, a sealing plug is arranged above the top end of the inner pipe. The inner pipe can be independently produced as a pipe fitting, and the upper end of the pipe fitting is generally left empty when the pipe fitting is just formed in consideration of convenience in manufacturing a water inlet channel, so that the requirement of sealing the top end of the inner pipe can be met by plugging the pipe fitting with a sealing plug at the later stage.
