The ratchet member 86 abuts against the switching shaft 83, so that the ratchet member 86 can push the switching shaft 83 to slide when pushed by the pressing member 85 to slide, or the switching shaft 83 can push the ratchet member 86 and the pressing member 85 to return when the switching shaft 83 is returned by the returning member 87.

When the pressing member 85 is pressed, the switching shaft 83 pushes the ratchet member 86 under the action of the reset member 87, so that the ratchet member 86 stably rests at a rest position 8211 near the water outlet end of the switching valve 8, and at this time, the water inlet end of the switching valve 8, the water passing channel 8221, the third hole 841 and the negative pressure cavity 892 are sequentially communicated, and both ends of the sealing member 84 are respectively subjected to the hydraulic force in the water passing channel 8221 and the hydraulic force in the negative pressure cavity 892, and because the stress area of the sealing member 84 in the negative pressure cavity 892 is larger than the stress area of the sealing member 84 in the water passing channel 8221, the sealing member 84 moves or deforms toward the water dividing hole 891 under the hydraulic force to seal the hole edge of the water dividing hole 891, so that the water outlet end of the switching valve 8 does not flow out, and deforms in this embodiment.

When the pressing piece 85 is pressed, the switching shaft 83 pushes the ratchet piece 86 under the action of the reset piece 87, so that the ratchet piece 86 stably stops at a stop position 8211 far away from the water outlet end of the switching valve 8, the switching shaft 83 stops at the second position, at this time, the water inlet end of the switching valve 8, the water passing loop 8221, the third hole 841, the negative pressure cavity 892, the fourth hole 842 and the water dividing hole 891 are sequentially communicated, the negative pressure cavity 892 and the water dividing hole 891 are depressurized, at this time, the action of the water force in the negative pressure cavity 892 on the sealing piece 84 is smaller, the sealing piece 84 is larger by the water force in the water passing loop 8221, so that the sealing piece 84 moves or deforms in a direction far away from the water dividing hole 891 under the water force to open the water dividing hole 891, in this embodiment, the deformation of the sealing piece 84 is lifted, so that the water inlet end of the switching valve 8 is directly communicated with the water dividing hole 891 after passing through the water passing loop 8221, and the water passing amount is increased in a pilot way, and the method is simple and convenient.

The water outlet device can realize the effects of temperature adjustment, water outlet adjustment and different water outlet mode switching by providing the water outlet inner core 1 with the proper temperature valve 7 and the proper switching valve 8, and has more various functions.

The water outlet device can close the switching valve 8 to outlet water through a button every time. The next time of use only needs to be pressed and opened again, water can be discharged from the gear after the last time of use, the use is more convenient, the water passing amount is increased in a pilot mode, and the method is simple and convenient; in addition, the switching valve 8 also has a function of rotating switching, and the water outlet sequence adjustment can be adjusted in a rotating mode after the switching valve 8 is closed, and when the water outlet sequence adjustment is adjusted to a desired water outlet gear, the switching valve is opened again, so that the gear water outlet without use can be avoided. The product comfort level is improved by fitting the actual use requirement.

It should be appreciated that in other embodiments, in which a thermostatic valve is not used, but only the ordinary temperature valve 7 is used, the length of the cold water inlet channel 13 is longer than that of the hot water inlet channel 14, so that the situation that the hot water inlet channel 14 is too long to cause the whole water outlet inner core 1 to be hot and easily scald a user can be prevented. While the positions of the cold water port 111 and the hot water port 112 are not limited to the ordinary temperature valve 7.

The foregoing description of the embodiments and description is presented to illustrate the scope of the utility model, but is not to be construed as limiting the scope of the utility model. Modifications, equivalents, and other improvements to the embodiments of the utility model or portions of the features disclosed herein, as may occur to persons skilled in the art upon use of the utility model or the teachings of the embodiments, are intended to be included within the scope of the utility model, as may be desired by persons skilled in the art from a logical analysis, reasoning, or limited testing, in combination with the common general knowledge and/or knowledge of the prior art.
