At this time, the water outlet cover 50 may be integrally composed of the soft rubber water outlet portion 53, the soft rubber water outlet portion 53 and the outer casing 60 are fixedly connected through the secondary injection molding, and after the outer casing 60 is fixedly connected to the fairing 40 or the flow limiting member 20, the top surface of the soft rubber water outlet portion 53 is just abutted to the bottom surface of the fairing 40 to form the corresponding water outlet cavity 74.

In addition, in another embodiment, a housing 60 fixedly connected with the fairing 40 may be further provided, a plurality of ribs are provided at the bottom of the housing 60, a plurality of grooves adapted to be inserted into the ribs are provided on the soft rubber water outlet portion 53, and part of the soft rubber water outlet portion 53 is exposed at the bottom of the housing 60, at this time, the soft rubber water outlet portion 53 may be installed downward from the inside of the housing 60, so that the soft rubber water outlet portion 53 is fixed on the housing 60, and then the fairing 40 is installed in the housing 60 and abutted to the top surface of the soft rubber water outlet portion 53 to form a corresponding water outlet cavity 74.

It should be noted that the soft rubber water outlet portion 53 in this embodiment has a larger radial dimension, which requires that the water outlet device needs to reduce the impact force of the water flow on the soft rubber water outlet portion 53 through multiple means, so as to avoid the large deformation of the soft rubber water outlet portion 53.

In the water outlet device provided by the present embodiment, the inlet water flow first passes through the filter 10, after large-sized particles are filtered out, enters the second water passing cavity 71, by the flow-limiting action of the flow-limiting rubber ring 61 and the flow-limiting member 20, a small part of water flows through the flow-limiting water passing hole 21 into the first water passing cavity 72 and then flows into the water passing hole 32 in a split manner, due to the structural characteristics of the water through holes 32, negative pressure is formed after water flow is injected into the gas-liquid mixing cavity 73, the water flow sucks air and forms bubble water through the vent grooves 36 and the air inlet channel 35, the sucked water flow is weakened, and the water is hit on the rectifying plate of the rectifying piece 40, is dispersed again for deceleration, loses most impact force after reaching the water outlet cavity 74 through the rectifying water through hole 47, and then forms water outlet through the water outlet hole 51 on the soft rubber water outlet part 53, so that the effect of reducing the deformation degree of the soft rubber water outlet part 53 is achieved.

The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the invention or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the invention.
