[0026] Referring to the drawings of the specification, a pull-out head capable of discharging soap liquid comprises a body 10, on which a matching water passage 11 and a water outlet are arranged, on which a matching soap liquid channel 12 and a soap liquid outlet 13 are also arranged, on which a matching first one-way valve 21 and a second one-way valve 22 are arranged, and on which a pressure cavity 20 is also arranged, and the pressure cavity can be connected to the soap liquid channel located between the first one-way valve and the second one-way valve, and in which a button 23 having one end that can be located outside the body is arranged, and a spring 24 is arranged between the button and the body, and pressing the button can drive the first one-way valve to open, and resetting the button can drive the second one-way valve to open, and by repeatedly pressing the button, the soap liquid can be continuously squeezed out from the second one-way valve and the first one-way valve from the soap liquid outlet, because the pull-out head itself can be movable relative to the kitchen sink, so that the position of the soap liquid outlet can be changed at will, so that the place where the soap liquid is squeezed out is the place where the soap liquid needs to be used, and there is no need to perform transfer work, which is simple and convenient.

[0027] Referring to the accompanying drawings, the second one-way valve and the first one-way valve are arranged on the soap liquid channel along the soap liquid outlet direction, that is, the soap liquid first passes through the second one-way valve and then is squeezed out of the first one-way valve. At the same time, in the process of squeezing out the soap liquid, the first one-way valve and the second one-way valve are switched between open and closed states at intervals. When the first one-way valve is open, the second one-way valve is closed. On the contrary, when the second one-way valve is open, the first one-way valve is closed. That is to say, when the soap liquid is outlet, the switch states of the first one-way valve and the second one-way valve are opposite.

[0028] In one embodiment of the utility model, the first one-way valve and the second one-way valve are duckbill valves. Since the duckbill valve can be controlled by pressure and has a low cost, the cost of the entire pull-out head can be kept low. Pressing the button can drive the first one-way valve to open and the second one-way valve to close, and the spring is compressed at this time; resetting the button can drive the second one-way valve to open and the first one-way valve to close, and the button is reset by resetting the spring and returns to its initial state, that is, one end face of the button abuts against the end face of the connecting ring.

[0029] Preferably, a sealing ring 25 is provided on the outer peripheral side of the button, and the multiple pressing processes of the button can be regarded as a piston. The outer periphery of the sealing ring can also be connected with the inner peripheral wall of the pressure cavity, so as to ensure that the soap liquid will not leak out and the pressure energy can act on the first one-way valve and the second one-way valve. One end of the pressure cavity is connected with the soap liquid channel. In the figure, it can be said that the lower end of the pressure cavity is connected with the soap liquid channel. A connecting ring 26 for limiting the button stroke is provided on the main body at the other end of the pressure cavity. The button can extend out of the main body through the inner periphery of the connecting ring, and one end face of the button can abut and cooperate with the end face of the connecting ring, so as to ensure that the button will not separate from the pressure cavity under the action of the spring.

[0030] Furthermore, it also includes a tube-in-tube structure 30, wherein the tube-in-tube structure includes an inner tube 31 and an outer tube 32 arranged inside and outside, wherein the channel of the inner tube is connected to the soap liquid channel, and the channel of the outer tube is connected to the water channel, and the channels of the inner tube and the outer tube are relatively independent and different, so that water can only pass through the water channel and the soap liquid can only pass through the soap liquid channel. One end of the body is connected with the tube-in-tube structure, and the other end of the body is provided with a panel 14, and the water outlet and the soap liquid outlet are provided on the panel.

[0031] Preferably, the body is further provided with a water diversion chamber 15 which can cooperate with the water passage, the water diversion chamber is provided with a switching mechanism 40, the body is provided with a first water outlet 41 and a second water outlet 42, the first water outlet and the second water outlet can be connected with the water diversion chamber.

[0032] Furthermore, the switching mechanism includes a button 43 arranged on the main body, one end of the button is connected to a movable shaft 44, the movable shaft is arranged in the water diversion chamber, and a first outlet 45 and a second outlet 46 are also arranged in the main body. The first outlet can be connected to the first water outlet, and the second outlet can be connected to the second water outlet. The movement of the movable shaft can connect the water channel to the first outlet or the second outlet through the water diversion chamber.

[0033] Furthermore, the water outlet includes a first water outlet 16 and a second water outlet 17, the first water outlet can be connected to the first outlet, and the second water outlet can be connected to the second outlet; the middle part of the button is hinged with the body to form a seesaw structure. The first water outlet is located at the periphery of the second water outlet, and the second water outlet is located at the periphery of the soap outlet. In one embodiment, the first water outlet can be a shower water outlet, and the second water outlet is a bubble water outlet.

[0034] More specifically, the utility model adopts a tube-in-tube structure, with the inner tube passing through the soap liquid and the outer tube passing through the water. In the water-passing state, by pressing the water outlet switch button, the water splash switching mechanism is activated, thereby switching the water splash effect; in the water-off state, by pressing the soap-feeding button, the pressure in the pressure cavity increases, the second one-way valve is closed, the first one-way valve is opened, the soap liquid in the pressure cavity is squeezed out through the first one-way valve, and the faucet discharges the soap liquid; when the soap-feeding button is released, the spring rebounds and resets the soap-feeding button, a negative pressure is formed in the pressure cavity, the first one-way valve is closed, the second one-way valve is opened, and the soap liquid is sucked into the pressure cavity from the inlet of the second one-way valve; repeating the above pressing and releasing states, continuously obtaining the soap liquid by pressing the button; integrating the soap-feeding function into the pull-out head saves countertop space and meets the use requirements of consumers, while greatly reducing the cost of use.
