In addition, the movable space required for lifting and lowering the top shower panel is relatively large. When it is used in a bathroom with a small space, the user needs to squat down to make way for the space when changing the use state. Finally, the degree of automation is low and the operating comfort is poor.

The disadvantages of the electric multifunctional combination shower are: due to the coexistence of water and electricity in the shower and the control system, there is a danger of electric shock during use, and absolute safety cannot be guaranteed; because electronic products need to be sealed in a humid and corrosive environment in the bathroom, it does not It is conducive to the heat dissipation of heat generated during the operation of electronic products, and the service life and reliability of the electronic electromagnetic control part will be affected; the electric control requires additional driving energy during use, and electronic waste will be generated after the service life of electronic products is over, which is not conducive to energy saving , Environmental protection work to reduce emissions.

Detailed ways

Referring to Fig. 1, a hydraulically controlled multifunctional shower of the present invention includes a shower main body 1 and a control device 2, the lower part of the shower main body 1 is respectively provided with a rubber nozzle 14 and a waterfall nozzle 15, and the upper part of the control device 2 is A control button 19 is installed, and the control device 2 is provided with a switching valve 17 and a hydraulic actuating cylinder 16, wherein the control button 19 drives the switching valve 17 to move through the lever 18, and the switching valve 17 is connected to the hydraulic actuating cylinder 16 through a pipeline to make the hydraulic actuating cylinder 16 control the opening and closing of the waterfall water nozzle 15 and spray water.

In this embodiment, the hydraulic actuating cylinder 16 includes a cylinder body 3, the side of the cylinder body 3 is provided with an actuating cylinder water inlet 16a and an actuating cylinder water outlet 16b, the actuating cylinder water outlet 16b communicates with the waterfall nozzle 15, and the cylinder body 3 A piston rod 20 that can move relative to the cylinder body 3 is arranged inside, and a reset spring 22 is set on the piston rod 20.

The hydraulic action cylinder 16 is a composite device of a hydraulic cylinder and a switch valve with an action sequence; when the water flow enters the cylinder, the piston moves forward under the hydraulic force, and when it reaches the set position, the screw connected with the piston rod pulls up the switch valve, Water flows out from the water outlet 16b of the hydraulic action cylinder 16, and flows in from the water inlet 15a of the waterfall water nozzle 15 through the pipeline, and finally flows out from the waterfall water nozzle 15. Because the hydraulic action cylinder 16 pushes the piston forward earlier, and then the water is discharged from the water outlet, that is, the waterfall water nozzle 15 will be screwed out to a certain position under the promotion of the piston of the hydraulic action cylinder 16, and then the waterfall water nozzle 15 will discharge water; The advantage of the design is that it not only ensures the simplicity and integrity of the appearance of the entire product in the closed state, but also effectively prevents the interior from suddenly spraying water when it is not opened during the opening process, resulting in false external visual leakage.

Now, because the water flow to the hydraulic cylinder 16 is interrupted, the piston that loses the hydraulic thrust resets under the action of the back-moving spring and drags the waterfall water nozzle 15 to close upwards. During the reset process of the hydraulic action cylinder 16, when the piston returns to the set position, the screw connected to the piston rod is lowered to open and close the valve, and the water flow to the waterfall water nozzle 15 is cut off, so as to prevent the waterfall water nozzle 15 from returning to the inside of the shower body. Spray water to cause false water leakage on the outside.

After shutting off the hydraulic action cylinder 16 to flow to the water flow of the waterfall water nozzle 15 directions, though the accumulated water inside the hydraulic action cylinder 16 still continues to be discharged, the hydraulic action cylinder 16 could fully reset and drag the waterfall water nozzle 15 to close completely. The water flow will return to the switch valve 17 along the original water inlet pipe, and flow out through the pressure relief water port 17d through the pressure relief channel made inside the switch valve 17, and then enter through the pipe from the pressure relief water port 13b of the top shower housing 13, and finally from The part of the shower rubber nozzle 14 is sprayed out from the separated small hole to realize the closing and reset of the waterfall water nozzle 15.

When the control button 19b is pressed, the pull rod 18 drives the switching valve 17, and the switching valve 17 is in an intermediate state. When the waterfall water nozzle 15 is in working state, the top shower is opened or kept to sprinkle water.
