Detailed description of the specification

The invention will now be further described with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 5, the energy-saving water nozzle provided by the present invention comprises a fixed body 1 connected to a water pipe at the end, a fluid guide 2 fixed in a cavity of the fixed body 2, and an adjusting sleeve 3 screwed on the outer side of the fixed body, and the fluid guiding body is a hollow structure having an open end, a closed end and a flow guiding hole 201 on the side wall, and the spray hole 101 at the top end of the fixed body communicates with the flow guiding hole through the flow guiding gap 4 and the water passing gap 5 at the tip of the fluid guiding body; The top end is provided with a water outlet 301 which communicates/intersects the communication between the water outlet and the fluid guiding wall guiding hole 102 when the adjusting sleeve is screwed/released with the fixing body.

The flow guiding gap is opened between the fixed body and the fluid guiding body, and the running water gap is opened between the fixed body and the adjusting sleeve. The technical solution has small adjustments to the overall structure of the fixed body, the fluid guiding body and the adjusting sleeve, and is a technical solution that the guiding gap and the running water gap are relatively simple and effective.

As shown in Figures 2 and 4, the outer diameter of one end of the fluid guiding orifice is smaller than the outer diameter of the inlet end of the fluid guiding body.

As shown in FIGS. 2 and 6, the energy-saving water nozzle further includes a limiting pin 7. The inner wall of the adjusting sleeve has a ring-convex structure 302, and the ring-shaped structure has an internal thread, and the internal thread cooperates with the external thread of the fixed body to realize the thread. The mounting body has a mounting hole on the side wall of the fixing body, and the limiting pin and the ring-shaped convex structure prevent the adjusting sleeve from coming off the fixing body.

As shown in Fig. 2, the energy-saving nozzle further includes a gasket 8 disposed between the top wall of the adjustment sleeve and the top wall of the fixed body. The energy-saving faucet further includes a sealing ring 9 disposed between the inner wall of the open end of the adjusting sleeve and the fixed outer wall.

There are two main states when the invention is used. Figure 7 shows the spray state, at this time the adjustment sleeve Description

The fixing body is in a tightening state, and the water flowing from the water pipe into the nozzle flows from the fixed body into the guiding fluid, and then passes through the diversion hole, and flows into the water gap through the guiding gap, and finally passes through the spraying hole after further increasing the pressure from the water passing gap. The atomized state is ejected from the water outlet. At this time, the flow gap is blocked, and water can only flow out of the nozzle through the spray hole. The invention is highly efficient in water saving during spraying, and can effectively satisfy the water contact with the skin when washing hands, avoiding waste of water and improving the utilization efficiency of water.

Figure 8 shows the flow state. At this time, the adjustment sleeve and the fixed body are in a loose state. The water flow gap connects the water outlet to the flow guiding wall guide hole, and the water flowing into the energy-saving nozzle is not shown in Fig. 7. The flow from the spray hole mainly flows through the flow guiding hole, the flow guiding gap, the flowing water hole and the flowing water gap, and flows out from the water outlet. The water sprayed from the spray hole is not sufficiently high in pressure to form a spray which is effectively surrounded by the outflow of the flow gap, and finally the water flowing out of the flow gap merges into the water column and flows out.

The invention takes into consideration the state of spraying and flowing water, meets the needs of different people for water saving in different situations, satisfies the needs of most people for flushing and water saving, and achieves the need of energy saving, water saving and living.

In conclusion, the above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
