Description

Waterway switching structure and shower head

Technical Field

The invention relates to a waterway switching structure and a shower head.

Background

The whole shower head is used as follows:

referring to fig. 18, in the default position, in the button-up state, water flows through the valve core 520 and reaches the water diversion assembly 200 through the switching assembly 600, as shown in fig. 16, the push rod 210 in the water diversion assembly 200 pushes the deflector rod 250 under the action of water pressure, and as the pushing distance increases, the head of the deflector rod deforms under the action of the limiting plate 232 of the water diversion cover to prepare for the gear teeth 242 on the hook driving wheel 240, and water flows from the opening 237 into the water diversion tray 260, at this time, three water through holes (263, 264) of the water diversion tray 260 and six water outlet holes 283 of the fixing seat cooperate to form a first water outlet function (3 water outlets out of 6 holes, 3 shields), and in this embodiment, the first water outlet function is outer ring shower water. At this time, the spring 220 is compressed, and the opening 237 is opened.

Referring to fig. 19, in a button-pressed state, the button is pressed down, the main waterway is temporarily cut off by the valve core 520 of the button assembly, referring to fig. 17, due to the disappearance of the action of the water pressure, the push rod 210 is reset rightward under the action of the spring 220, the shift lever 250 is driven to move from left to right, and in this process, the trip 253 of the shift lever 250 acts with the gear teeth 242 of the driving wheel 240, so that the driving wheel 240 rotates by a certain angle. Meanwhile, the driving wheel 240 drives the water distribution disc 260 to rotate by the same angle, gear switching is completed, water outlet function switching of the shower is completed, but the main waterway is cut off because the button is not loosened, and the shower is temporarily not discharged. In this position, the opening 237 is blocked or obscured by the enlarged portion of the push rod 210.

Referring to fig. 20, in the push button up state, the push button is released, the main waterway resumes water supply, the push rod in the water diversion assembly regains the force of water pressure, the push rod 210 pushes the deflector rod under the force of water pressure, the head of the deflector rod touches the limit plate 232 of the water diversion cover, and then a certain deformation occurs (but the driving wheel cannot move, and the water diversion disc cannot rotate reversely because the water diversion disc is provided with the anti-rotation teeth 265), so that preparation is made for next gear switching. Because the main waterway resumes the water supply, the water outlet mode of the shower is the second water outlet function, and in the embodiment, the second water outlet function is the mixed water.

Referring to fig. 21, in the button re-pressing state, when the button is re-pressed, the main waterway is temporarily cut off by the valve core 520 of the button assembly, the push rod in the water diversion assembly loses the acting force of water pressure, and is reset under the acting force of the spring, in the resetting process, the trip on the deflector rod hooks the gear teeth on the driving wheel to rotate for one angle again, meanwhile, the driving wheel drives the water diversion disc to rotate for the same angle, gear switching is completed, and the water outlet function of the shower head is switched to a next gear.

Referring to fig. 22, the button is in a sprung state again, the button is released, the water is restored to the main waterway, the push rod in the water diversion assembly regains the acting force of the water pressure, the push rod pushes the deflector rod under the acting force of the water pressure, the head of the deflector rod touches the limit plate 232 of the water diversion cover, and a certain deformation is generated, so that preparation is made for the next gear shift. Because the main waterway resumes the water passage, the water outlet mode of the shower head is the third water outlet function, and in the embodiment, the third water outlet function is the middle shower head.

In other embodiments, the button assembly is not required, and the faucet switch of the sprinkler is adopted for on-off of the waterway. The faucet switch is universal, can adjust the cold and hot water proportion, can adjust the knob switch of rivers size again, this switch is installed in cold and hot water governing valve department, can adjust cold and hot water proportion when the handle is rotatory, can control the rivers size when the handle lifts or presses.
