In the embodiment, the first angle and the second angle only represent the angle of the liquid bottle and the body, and the specific values are not limited.

[0028] In combination with Figures 1 to 6 As shown in the drawings, in the embodiment, the water outlet structure can be a pull head mounted on a faucet, or a shower head mounted on a bathing device, or a spray head mounted on a spray gun device, but is not limited to this. Specifically, the embodiment takes the pull head arranged on the faucet as an example for description, the water outlet structure comprises a body 1, the body 1 comprises a shell and an outlet channel 11 arranged in the shell, and the outlet end of the outlet channel 11 is provided with a bubbler 16 or a filter or a plurality of filter sheets, so that foam can be quickly generated when water mixed with cleaning liquid flows out, and the cleaning effect is improved. Further, the upstream end of the outlet channel 11 is provided with a water stopping channel 14, water flows into the outlet channel 11 after passing through the water stopping channel 14, and a water stopping key 15 is arranged on the water stopping channel 14, so that the water stopping channel 14 can be closed by one key by pressing the water stopping key 15, thereby achieving the effect of quickly stopping water. Of course, in other embodiments, the body 1 of the water outlet structure can also adopt the existing structure. In addition, the water outlet structure can also be provided with a switching function to switch the water spray effect, so that different water spray effects can better generate foam.

[0029] In combination with Figure 6 and Figure 7As shown, the water outlet passage 11 is provided with a Venturi structure 12, which includes an inlet portion 121, a diffusion portion 122, a contraction portion 123 and an outlet portion 124; the cross-sectional area of the outlet portion 124 is larger than that of the inlet portion 121; the diffusion portion 122 is connected to the inlet portion 121 and the contraction portion 123 at two ends thereof, and the cross-sectional area of the diffusion portion 122 is larger than that of the inlet portion 121 and the contraction portion 123; the contraction portion 123 is connected to the diffusion portion 122 and the outlet portion 124 at two ends thereof, and the cross-sectional area of the contraction portion 123 gradually decreases from the diffusion portion 122 to the outlet portion 124; the diffusion portion 122 is provided with a liquid inlet passage 125 to communicate with the communication passage. Here, the contraction portion 123 has a conical structure, and the cross-sectional area of the contraction portion 123 gradually decreases from the diffusion portion 122 to the outlet portion 124. The cross-sectional areas of the inlet portion 121 and the outlet portion 124 are both smaller than the cross-sectional area of the water inlet passage, so that when the water flow passes through the inlet portion 121, the water flow is accelerated due to the decrease of the cross-sectional area. The cross-sectional area of the diffusion portion 122 is larger than that of the inlet portion 121, and the cross-sectional area of the diffusion portion 122 is also smaller than that of the water outlet passage. The water pressure at the diffusion portion 122 is lower than the air pressure in the liquid bottle 2, so that the cleaning liquid in the liquid bottle 2 is sucked out into the water passage and mixed with the water flow to flow out. In other embodiments, the Venturi structure 12 can also have an existing structure.

[0030] Continuing with Figure 6As shown, the liquid bottle 2 comprises a bottle body, a liquid supplement port 21 arranged at the top end of the bottle body, and a connecting portion 22 arranged at the bottom side of the bottle body, the connecting portion 22 is provided with a liquid outlet channel to communicate with the communicating channel 13. The liquid supplement port 21 can be used to supplement cleaning liquid. The connecting portion 22 can be rotatably arranged on the body 1 and adapted to rotate between a first angle and a second angle. Specifically, a mounting groove can be arranged on the body 1 to cooperatively connect the connecting portion 22, a sealing surface is arranged on the groove surface of the mounting groove, and a communicating channel 13 communicating with the Venturi structure 12 is arranged, the liquid outlet channel is eccentrically arranged on the connecting portion 22, and the connecting portion 22 can be rotatably mounted in the mounting groove through a threaded structure or a buckle structure, when the liquid bottle 2 is rotated to the first angle, the liquid outlet channel is blocked by the sealing surface in the mounting groove, so that the cleaning liquid cannot flow out, when the liquid bottle 2 is rotated to the second angle, the liquid outlet channel communicates with the communicating channel 13, and the liquid flows into the water outlet channel 11 under the suction of the water outlet channel 11, when the liquid is not needed, the liquid bottle 2 only needs to be rotated to the first angle to close the cleaning liquid outlet. In a preferred embodiment, the liquid bottle can be steplessly adjusted from the first angle to the second angle, that is, it can be switched between multiple angles, because the communication opening of the liquid outlet channel and the communicating channel gradually increases or gradually decreases during rotation, so different liquid outlet speeds can be achieved by adjusting different angles.

[0031] The liquid supplement port 21 is provided with a one-way air inlet valve. Specifically, the one-way air inlet valve is arranged as a duckbill valve 3, the duckbill valve 3 comprises an air inlet channel 31, two elastic sheets 32 are arranged on both sides of the air inlet channel 31, the ends of the two elastic sheets 32 are connected to each other to block the air inlet channel 31, and when the pressure in the liquid bottle 2 is less than the atmospheric pressure outside the liquid bottle 2, the two elastic sheets 32 are separated to open the air inlet channel 31. When the two elastic sheets 32 block the air inlet channel 31, they form a V-shaped structure with the tip pointing towards the inside of the liquid bottle 2. In this embodiment, the duckbill valve 3 can be made of rubber material, which is convenient to disassemble at the liquid supplement port 21 for liquid supplement, and also has a good sealing effect. The elastic sheets 32 are also made of rubber material, and in a natural state, the ends of the two elastic sheets 32 abut each other to form a V-shaped structure, which can block the air inlet channel 31 and prevent the cleaning liquid from flowing out of the air inlet channel 31. When the liquid bottle 2 is rotated to the second angle, the water outlet channel 11 generates suction in the liquid bottle 2, at this time the air pressure of the water outlet channel 11 is lower than the air pressure in the liquid bottle 2, so the liquid in the liquid bottle 2 can be quickly sucked into the water outlet channel 11, when the air pressure in the liquid bottle 2 is lower than the atmospheric pressure, the elastic sheets 32 are deformed under the action of the atmospheric pressure, so that the communicating channel 13 is opened to supplement air into the liquid bottle 2.

[0032] The liquid bottle 2 can store cleaning liquid such as hand sanitizer and shower gel. When in use, the liquid bottle 2 is rotated to align with the connecting channel of the installation groove, so that the liquid bottle 2 can be connected freely. At this time, when water flows through the Venturi tube structure 12 from the water outlet channel 11, the water flow is transitioned from a small hole to a large hole to generate suction, so that the cleaning liquid in the liquid bottle 2 is sucked through the connecting channel 13 and foamed through the bubbler 16 or the multiple layers of filter screens.

[0033] In a preferred embodiment, the water outlet channel 11 is provided with a one-way valve 4 at the upstream end of the Venturi tube structure 12. The one-way valve 4 can prevent the cleaning liquid from being sucked into the upstream water source when the water flow in the water outlet channel 11 reverses, thereby achieving a protection effect.

[0034] In the embodiment, the liquid bottle 2 can be rotated under the control of the user to control whether the liquid bottle 2 is connected with the water outlet channel 11. The Venturi tube structure 12 provided in the water outlet channel 11 can provide suction to the liquid bottle 2 to suck out the cleaning liquid when the liquid bottle 2 is at the second angle. The bubbler 16 provided at the water outlet of the water outlet structure can quickly generate cleaning liquid foam to improve the cleaning effect, so that the user can generate a large amount of foam without hand rubbing during cleaning. Through the embodiment, the cleaning liquid can be extracted into the water outlet channel 11 without a pump body, and the control is convenient. When the cleaning liquid is not needed, closing the liquid bottle 2 does not affect the normal water outlet, and the overall structure is compact and not easy to damage.

[0035] It should be understood that the above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiments. Any technical solution falling within the scope of the present application is within the protection scope of the present application.
