[0028] 14. The water outlet of claim 13, wherein the water outlet of the water channel body is provided with a first water diversion chamber 12 connected to the water inlet 11 thereof, wherein the first water diversion chamber is provided with a first switching mechanism 30, and further comprising a first water outlet 13 and a water diversion chamber 14 which can be communicated with the first water diversion chamber, wherein the first water outlet can be connected to the water outlet panel, and the water flow of the first water outlet directly flows to the first water outlet hole of the water outlet panel and flows out; a second water diversion chamber 15 which is connected to the water diversion chamber is provided in the water channel body, wherein the second water diversion chamber is provided with a second switching mechanism 40; further comprising a second water outlet 16 and a third water outlet 17 which can be communicated with the second water diversion chamber, wherein the second water outlet and the third water outlet can be connected to the water outlet panel; further comprising a button 50, wherein the middle portion of the button is hinged to the outer periphery of the water channel body to form a seesaw pattern, wherein one end of the button abuts against the first switching mechanism, and the other end of the button abuts against the first switching mechanism, and the other end of the button abuts against the first switching mechanism. The second switching mechanism is in abutment with each other, that is, the two ends of the button can only contact with the first switching mechanism (first center bolt) and the second switching mechanism (second center bolt), and they do not necessarily need to be hooked together. In one use of the utility model, when the button is not pressed (that is, when no force is applied), the button can maintain a horizontal state under the action of the first spring and the elastic member. If the other end of the button is pressed, the second switching mechanism completes the switching, that is, the second center bolt moves down. At this time, release your hand and the button returns to the original horizontal state under the state of the elastic member. If one end of the button is pressed, the first switching mechanism switches at this time, and only by keeping one end of the button pressed can the first water outlet be kept for water to flow out. If it is released, the button will be driven to return to its original horizontal state under the action of the first spring. In other words, no matter whether the pull-out head flows out water or not, as long as the two ends of the button are not pressed, it will remain in the original horizontal state.

[0029] Preferably, the first switching mechanism includes a first bushing 31 with a hollow middle portion, the first bushing is arranged above the first water diversion chamber, a first center plug 32 is arranged in the middle of the first bushing, a first opening 121 which can be connected with the water diversion path is arranged below the first water diversion chamber, a first water inlet 33 is arranged at the lower end of the middle portion of the first bushing, a first sealing ring 34 is arranged at the outer periphery of the lower end of the first center plug, the first sealing ring can be sealed with the side walls of the first opening and the first water inlet, so that water can be discharged selectively.

[0030] Furthermore, a first spring 35 is provided between the lower end of the first center plug and the first water diversion chamber, and the upper end of the first center plug can abut and cooperate with one end of the button; when the first center plug is not subjected to force, the first spring can drive the first center plug to move upward, so that the first sealing ring is sealed and cooperated with the first water inlet, and the water flows from the first water diversion chamber to the second water diversion chamber via the water diversion path. The "no force" mentioned here refers to different external artificial forces, that is, the force of the first spring is greater than the water pressure of the water flow. The first center plug will be driven to reset by the first spring when there is only water pressure. This state can only be maintained by manually pressing the button and compressing the first spring. As long as you let go, the first center plug will be reset.

[0031] Furthermore, a first water outlet 36 is also provided on the peripheral side wall of the first bushing, and the first water outlet can be connected to the first water outlet; when the first sealing ring is sealed with the first opening, water flows from the first water diversion cavity through the first water inlet, the middle of the first bushing, and the first water outlet to the first water outlet.

[0032] In a preferred embodiment of the utility model, an elastic member 60 is further provided on the water channel body. The elastic member can be an elastic sheet or a spring. One end of the elastic member can be connected with the other end of the button. The elastic member can drive the button to reset after the switching of the second switching mechanism. When the button is in the original horizontal state, the elastic member is in a free state and abuts against the other end of the button. When the other end of the button is pressed down by force, the elastic member is compressed and accumulates force, and the force on the other end of the button is released. The elastic member will drive the button to return to its original horizontal state, but at this time the second water outlet and the point outlet have completed the switching.

[0033] Preferably, the second switching mechanism includes a second bushing 41 with a hollow middle portion, the second bushing is arranged above the second water diversion chamber, a second center plug 42 is arranged in the middle of the second bushing, a second opening 151 which can be connected with the second water outlet is arranged below the second water diversion chamber, a second water inlet 43 is arranged at the lower end of the middle portion of the second bushing, a second sealing ring 44 is arranged at the outer periphery of the lower end of the second center plug, and the second sealing ring can seal with the side walls of the second opening and the second water inlet.

[0034] Furthermore, a second spring 45 is provided between the lower end of the second center plug and the second water diversion chamber, and the upper end of the second center plug can be abutted and matched with the other end of the button; when the second center plug is not subjected to force and there is water flow in the second water diversion chamber, the second spring cannot drive the second center plug to move upward, so that the water flow in the second water diversion chamber keeps flowing to the second water outlet or the third water outlet, that is, the water flow in the second water diversion chamber is greater than the force of the second spring, so that the second water outlet and the third water outlet keep the same water outlet when they are not subjected to the switching mechanism. When there is no water flow in the cavity, the second spring will drive the second center plug to move upward, so that when there is water flow in the second water diversion cavity next time, water will flow out of the second water outlet. In other words, the default water outlet of the pull-out head is the second water outlet, that is to say: when there is no water flow (water pressure) in the second water diversion cavity, the second center plug will be reset under the action of the second spring. Preferably, the force of the first spring is greater than the force of the second spring, because the first spring can overcome the water pressure by itself to achieve the reset of the first center plug, while the second spring cannot overcome the water pressure by itself to achieve the reset of the second center plug.

[0035] Furthermore, a second water outlet 46 is also provided on the peripheral side wall of the second bushing, and the second water outlet can be connected to the third water outlet; when the second sealing ring is sealed with the second water inlet, water flows from the second water diversion chamber through the second opening to the second water outlet; when the second sealing ring is sealed with the second opening, water flows from the second water diversion chamber through the second water inlet, the middle part of the second bushing and the second water outlet to the third water outlet.

[0036] It also includes a shell 70, the water channel body is arranged in the shell, one end of the shell is provided with a water outlet panel connected to the water channel body, the outer periphery of the shell is provided with an opening 71, and the button is arranged at the opening; when the button is not subjected to force, the button can maintain a horizontal state with the shell. The water outlet panel is provided with a first water outlet hole 21 that can be connected to the first water outlet, which can be a soft water outlet hole, the water outlet panel is provided with a second water outlet hole 22 that can be connected to the second water outlet, which can be a shower water outlet hole, and the water outlet panel is provided with a third water outlet hole 23 that can be connected to the third water outlet, which can be a blade water outlet hole.

[0037] The utility model is more specific: a single-button three-function pull-out head: including a water inlet, a first switching mechanism, a first water outlet, a second switching mechanism, a second water outlet, a third water outlet, a button, and a water outlet panel; wherein the water inlet is connected to the first switching mechanism, one way is connected to the first water outlet, and the other way is connected to the second switching mechanism, and the second switching mechanism connects the second water outlet and the third water outlet. The first and second switching mechanisms are conventionally at the top, holding the button to maintain a horizontal state, and the second water outlet is opened; pressing the other end of the button drives the second center bolt to move down and switch, the third water outlet is opened, and the second water outlet is closed; pressing one end of the button drives the first center bolt to be pressed for a long time, the first water outlet is opened, and the second and third water outlets are closed. At this time, under the action of the second spring, the second center bolt moves up, and when the first center bolt is released and reset, it resets to the second water outlet to open. There is a fulcrum in the middle of the button, and the button is installed on the outer periphery of the water channel body. The inner surfaces at both ends of the button contact the first center plug and the second center plug respectively. When the button is pressed forward to drive the second center plug to move downward, it switches to the third water outlet. At the same time, due to the pressure of water, the second center plug is stabilized and does not move, and the third water outlet is kept out. At the same time, there is an elastic part on the second switching mechanism to restore the button to its original state. When the first center plug is pressed backward for a long time, it switches to the first water outlet state. After the hand is released, due to the first spring with a strong spring force, the first center plug automatically resets, so that the water flows from the water diversion and the second water outlet. At the same time, the second center plug loses the pressure of water due to the water flow interruption, and the second center plug automatically resets to the top position under the spring force of the second spring. The first center plug is installed in the second water diversion chamber, and the second center plug is installed behind the second water diversion chamber.

[0038] The above description shows and describes the preferred embodiments of the utility model. As mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
