After the shower water is not needed, one side of the key 22, which is far away from the clamping portion 49, is pressed, the key 22 at one end of the clamping portion 49 is moved, in the moving process, the convex lug 50 drives the ball 48 to move, the key 22 and the switching rod 21 return, at the moment, water flows into the lower portion of the third mounting groove from the second mounting groove 12, and water pressure cannot act on the return spring 29 of the shower water switching component 4 to produce bubble water.

The working principle of the utility model is as follows:

after the valve of the drawing head is opened, water enters from the water inlet channel 10 and flows along the first water channel 17, and water flows out from the foaming water hole 45, the water is soft, the water cannot splash outside the washing basin or onto a user body at one time, unnecessary troubles are reduced, the water which flows out at the moment is less in sprinkling, and the water which is not used when just opened is not used, so that more water cannot be wasted, and the water-saving effect is achieved. Press the bottom of the button 22 of the shower water switching subassembly 4, switching lever 21 extrudes return spring 29, first inclined plane 16 is plugged up to first sealing washer 28, and first sealing washer 28 compresses tightly first inclined plane 16 under the water pressure effect, hydraulic effort is greater than return spring 29's elasticity this moment, loosen the hand after, switching lever 21 can not the return, water flows out from gondola water faucet water hole 36 through second water course 18, the shower water is the normal water, the relative bubble water of rivers is great and pressure is also great. After the shower water is not needed, the top of the button 22 of the shower water switching component 4 is pressed, the switching rod 21 returns to the original state, and the bubbling water is discharged; or the button of the spray water switching component or the blade water switching component can be directly pressed, and when the button is pressed, water can not enter the upper part of the third mounting groove, and no water pressure overcomes the acting force of the return spring 29 of the shower water switching component 4, so that the switching rod 21 can return. When a long time washing is required and a large amount of water and a large water pressure are not required, such as a washing tub, the button 22 of the spray water switching unit 2 is pressed, the switching lever 21 presses the return spring 29, the first seal ring 28 is separated from the first inclined surface 16 and presses the second inclined surface 24, and water flows along the third water passage 19, and the spray water hole 35 sprays water. After the hands are released, the water returns to the foaming water holes 45 to discharge water. When garbage, grapes and the like in the wash basin need to be cleaned under high water pressure, the button 22 of the blade water switching assembly 3 is pressed, the switching rod 21 of the blade water switching assembly presses the return spring 29, the first sealing ring 28 leaves the first inclined surface 16 and presses the second inclined surface 24, water flows along the fourth water channel 20, and the blade water hole 44 discharges the water. After the hands are released, the water returns to the foaming water holes 45 to discharge water. Has four channels, and can select proper water outlet state according to the requirement.

In addition, the arrangement of the spray water hole 35 can be cancelled on the water outlet panel 5, so that when the drawing head needs to be moved from the water pool to another water pool under the condition that the valve of the drawing head is opened, the button of the spray water switching assembly can be directly pressed without closing the valve, at the moment, water is temporarily closed due to the absence of the spray water hole 35, the water cannot splash to the ground or other objects when the drawing head moves, and the purpose of conveniently moving the drawing head at a higher speed compared with the purpose of closing the valve is achieved. The appearance is changeable, and the practicality is stronger.
