[0055] Reference Figure 2 and Figure 3 As shown, the water outlet device 1000 also includes a first pipe 200 and a second pipe 300. The first pipe 200 and the second pipe 300 are arranged in the shell 100. The first pipe 200 and the second pipe 300 are arranged side by side to reduce the occupied space. The first pipe 200 is used to connect the water inlet end 110 and the water outlet end 120, and the second pipe 300 is also used to connect the water inlet end 110 and the water outlet end 120. The first pipe 200 is mainly used to increase the water outlet flow rate, and the second pipe 300 is mainly used to increase the foaming amount of the cleaning liquid and increase the water pressure.

[0056] Specifically, refer to Figure 8 As shown, Figure 8 The cross-sectional view of the second pipe 300 is shown. The second pipe 300 includes a first pipe section 310 and a second pipe section 320 connected to each other. The first pipe section 310 and the second pipe section 320 are connected in sequence along the water outlet direction. Figure 8 Refer to the direction of the arrow in Figure 9 As shown, the first pipe section 310 includes a first inlet section 311, a first throat section 312 and a first outlet section 313 arranged in sequence along the water outlet direction. The cross-sectional area of ​​the first inlet section 311 and the cross-sectional area of ​​the first outlet section 313 are respectively larger than the cross-sectional area of ​​the first throat section 312. The second pipe section 320 includes a second inlet section 323, a second throat section 324 and a second outlet section 325 arranged in sequence. The first outlet section 313 is connected to the second inlet section 323. The cross-sectional area of ​​the second inlet section 323 and the cross-sectional area of ​​the second outlet section 325 are respectively larger than the cross-sectional area of ​​the first throat section 312. The cross-sectional area of ​​the second throat section 324, the outer wall of the first outlet section 313 or the outer wall of the second inlet section 323 is provided with a connector 326, the connector 326 is provided with a first through hole 321, the first through hole 321 is connected to the second pipe 300, the connector 326 is mainly used to connect with the second infusion tube 500, the connector 326 is a cylindrical structure, the second infusion tube 500 can be sleeved on the outer circumference of the connector 326, the first through hole 321 can inhale cleaning liquid, the outer wall of the second outlet section 325 is provided with a second through hole 322, the second through hole 322 can inhale air.

[0057] It should be noted that in some embodiments, the first pipe segment 310 and the second pipe segment 320 can be arranged as a Venturi tube.

[0058] In operation, referring to Figure 3 , the external clean water enters the water inlet end 110 and is distributed into the first pipe 200 and the second pipe 300, when the cleaning liquid is needed to be discharged, the second liquid pipe 500 is connected to the connecting head 326, so that the second liquid pipe 500 is in communication with the first through hole 321, the clean water first passes through the first pipe segment 310 and then passes through the second pipe segment 320, when the clean water passes through the first pipe segment 310, referring to Figure 8 , the clean water sequentially passes through the first inlet segment 311, the first throat segment 312 and the first outlet segment 313, according to the Venturi principle, the speed of the water flow in the first throat segment 312 and the first outlet segment 313 will be increased, and a negative pressure will be generated at the position of the first outlet segment 313, that is, an adsorption force is generated, since the first through hole 321 is in communication with the first outlet segment 313, the cleaning liquid in the second liquid pipe 500 can be sucked into the second pipe 300 through the first through hole 321, without the need to set a power device to push the cleaning liquid, the manufacturing cost can be reduced, the cleaning liquid and the clean water are fully mixed in the first pipe segment 310 to form a mixed liquid, then the mixed liquid continues to flow, when the mixed liquid passes through the second pipe segment 320, the mixed liquid sequentially passes through the second inlet segment 323, the second throat segment 324 and the second outlet segment 325, according to the Venturi principle, the speed of the mixed liquid in the second pipe segment 320 will be further increased, and a negative pressure will be generated at the position of the second outlet segment 325 of the second pipe segment 320, since the second through hole 322 is in communication with the second outlet segment 325, the external air can be sucked into the second pipe segment 320 through the second through hole 322, so that the mixed liquid in the second pipe segment 320 is fully mixed with the air, the amount of foaming of the mixed liquid is increased, which is also beneficial to the flow of the mixed liquid, and a pressurization effect is achieved, finally, the mixed liquid in the second pipe 300 and the clean water in the first pipe 200 flow into the water outlet end 120 and flow out of the water outlet end 120.

[0059] When the water discharge device 1000 is not needed to discharge the cleaning liquid, the second liquid pipe 500 can be directly disconnected from the connecting head 326, at this time, the second liquid pipe 500 does not hinder the user's hand, and the hand is convenient to hold the shell 100, referring to Figure 8 and Figure 9When the clean water in the second pipeline 300 passes through the first pipe section 310 and the second pipe section 320, according to the Venturi principle, the water flow speed will become large, and the first outlet section 313 of the first pipe section 310 and the second outlet section 325 of the second pipe section 320 will generate negative pressure. Since the first through hole 321 is in communication with the first outlet section 313 of the first pipe section 310, and the second through hole 322 is in communication with the second outlet section 325 of the second pipe section 320, external air can be sucked into the second pipeline 300 through the first through hole 321 and the second through hole 322, play a role in increasing pressure, improve the water experience, and the air and clean water mixed can also play a water-saving effect.

[0060] Finally, it should be noted that the water outlet device 1000 of the utility model is provided with the first pipeline 200 and the second pipeline 300, the second pipeline 300 is used for outputting clean liquid and plays a role in increasing pressure, the first pipeline 200 is used for outputting clean water and increasing water flow, can take into account the effect of increasing pressure and ensure that the water flow is large, thereby improving the user experience.

[0061] It should be noted that the first through hole 321 and the second through hole 322 are sequentially arranged along the water outlet direction, which can be understood as sucking clean liquid at the first through hole 321 and then sucking air at the second through hole 322. The advantages of this are: 1. The suction of air helps to form foam of the clean liquid. In the bubble formation system, the clean liquid is the dispersion medium, and the gas is the dispersed phase. Since there is surface tension, the gas must be dispersed in the liquid to form bubbles, and then form foam by countless bubbles. 2. The clean liquid inlet position is relatively close to the water inlet end 110 of the shell 100, i.e. the position of the connecting head 326 is relatively close to the water inlet end 110 of the shell 100, which does not affect the holding of the shell 100. 3. The first through hole 321 and the second through hole 322 are arranged on the same part, i.e. arranged on the second pipe section 320, which can facilitate the manufacturing and processing of the first through hole 321 and the second through hole 322.

[0062] Referring to Figure 5 and Figure 8 In some embodiments, the connecting head 326 is connected with the second inlet section 323 of the second pipe section 320, and the axis of the connecting head 326 is perpendicular to the axis of the second inlet section 323. The connecting head 326 of the present embodiment can be conveniently connected with the second liquid conveying pipe 500, and the position of the connecting head 326 is relatively close to the water inlet end 110, which does not hinder the user to hold the shell 100.

[0063] In some embodiments, a one-way valve can be arranged at the connecting head 326, which is arranged to allow fluid outside the second pipe 300 to pass through the first through hole 321 only, and fluid inside the second pipe 300 cannot flow out of the second pipe 300 through the first through hole 321. After the second infusion pipe 500 is removed, leakage of liquid inside the second pipe 300 to the outside through the first through hole 321 can be avoided.

[0064] In some embodiments, the aperture of the first through hole 321 and the aperture of the second through hole 322 can be arranged to be small, and specifically, the aperture of the second through hole 322 is smaller than the aperture of the first through hole 321. Since the aperture of the second through hole 322 is small, leakage of liquid inside the second pipe 300 to the outside through the second through hole 322 can be avoided.

[0065] Referring to Figure 8 In some embodiments, the length of the first pipe segment 310 is smaller than the length of the second pipe segment 320. When the total length of the second pipe 300 is constant, the length of the second pipe segment 320 can be as long as possible, which is beneficial to enhancing the Venturi effect of the second pipe segment 320. The first through hole 321 is arranged on the outer peripheral wall of the second inlet segment 323, and the second through hole 322 is arranged on the outer peripheral wall of the second outlet segment 325.

[0066] In other embodiments, the length of the first pipe segment 310 can be substantially the same as the length of the second pipe segment 320. The first through hole 321 is arranged on the outer wall of the first outlet segment 313 of the first pipe segment 310, and directly connects the inner cavity of the first outlet segment 313 with the outside of the first pipe segment 310. The second through hole 322 is arranged on the outer wall of the second outlet segment 325 of the second pipe segment 320, and directly connects the inner cavity of the second outlet segment 325 with the outside of the second pipe segment 320.

[0067] Referring to Figure 4 In some embodiments, the first pipe 200 is provided with a connecting cover 210 at one end close to the water inlet end 110. The water outlet device 1000 further includes a nut member 220 and a connector 230. The connector 230 is connected with the first infusion pipe 400, the nut member 220 is threadedly connected with the connector 230, and the nut member 220 is further threadedly connected with the shell 100. The nut member 220 is in abutment with the connecting cover 210. The nut member 220 is of a hollow structure. The connecting cover 210 is provided with a first opening and a second opening. The first opening connects the inner cavity of the nut member 220 with the first pipe 200, and the second opening connects the inner cavity of the nut member 220 with the second pipe 300. The clean water in the first infusion pipe 400 can be allowed to pass into the first pipe 200 and the second pipe 300.

[0068] Referring to Figure 4 and Figure 5As shown, in some embodiments, the first pipe segment 310 is connected to the connecting cover 210 as an integral structure, facilitating processing and manufacturing.
