The emergence of products such as toilet foam shields, faucet foam hand washes, kitchen faucet foam cleaning, and showers has not only improved the user experience, but also brought revolutionary changes to bathroom cleaning and water conservation. The mixing structure of the corresponding bathroom products on the market is complex, and additional kinetic energy is required during extraction and mixing. It is impossible to automatically extract the detergent and mix it with water. The product is large-scale and not suitable for home use. Its structure is fixed and cannot be adjusted. When installing the corresponding structure, it is necessary to cut a section of the middle of the pipeline, apply glue to one end of the mixing device and connect it to one end of the pipeline, and then use a hot air blower to soften the other end of the pipeline and bend it downward to quickly plug it into the other end of the device, and then wait for the pipeline to cool and shape. Its connection structure is fixed and unchanged, which is not convenient for it to cooperate with the pipeline. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 , 2 As shown in Figures 3, 4 and 5, the utility model provides a technical solution: a structure with the function of hydraulic negative pressure absorption of mixed foam, comprising: a mixing valve body 1 with a water inlet pipe 4 and a water outlet pipe 5 respectively fixedly connected at both ends; a water inlet chamber 7 is arranged inside the mixing valve body 1, the water inlet pipe 4 is connected to the water inlet chamber 7, the water inlet chamber 7 is a funnel-shaped structure, used to increase the pressure of the water flow; a water outlet chamber 6 is arranged inside the mixing valve body 1, the water outlet chamber 6 is connected to the water inlet chamber 7; a foam stock solution absorption pipe 2 vertically penetrates the mixing valve body 1 from top to bottom and is fixedly connected to the mixing valve body 1, the water outlet chamber 6 and the water inlet chamber 7 are both connected to the foam stock solution absorption pipe 2, a negative pressure zone is formed by changing the pressure of the water flow, and the absorbed air and the foam stock solution are mixed and sprayed out here; a contraction and extension component is arranged on the outside of the water outlet pipe 5, the contraction and extension component comprises an extension interface 8 which can move along the water inlet pipe 4, used to adjust the length of the water inlet pipe 4 so that it can be installed in coordination with the water pipe.

[0027] It should be noted that the water inlet chamber 7 and the water outlet chamber 6 of the utility model form a channel that changes from thick to thin and then thick again. The channel runs through the middle of the foam stock solution suction pipe 2. According to the principle of the Venturi effect, when the airflow blows through the obstacle, the air pressure near the port above the leeward side of the obstacle is relatively low, thereby generating an adsorption effect and causing the air to flow. It changes the airflow from thick to thin to speed up the gas flow rate, so that the gas forms a "vacuum" area on the rear side of the Venturi tube outlet. When this vacuum area is close to the foam stock solution suction pipe 2, it will produce a certain adsorption effect on the foam stock solution suction pipe 2, thereby extracting the foam stock solution into the mixing valve body 1 to mix with water to form foam, and then discharge it from the water outlet pipe 5.

[0028] See also Figure 2, 4 As shown, the water outlet chamber 6 is a trumpet-shaped structure and its internal diameter increases successively along the water inlet direction, and the water outlet chamber 6 is concentric with the water inlet chamber 7, the water outlet pipe 5 is connected to one end of the water outlet chamber 6, the top of the mixing valve body 1 is fixedly connected with the air inlet pipe 3, and the foam concentrate suction pipe 2 is connected to the air inlet pipe 3.

[0029] It should be noted that the outer side of the air inlet pipe 3 of the utility model is connected with an air flow regulating valve, which controls the amount of air entering the mixing valve body 1, so that the internal negative pressure can effectively form an adjustable adsorption amount. Under the pressure of the water flow and the cooperation of the water outlet chamber 6 and the water inlet chamber 7, a negative pressure is formed in the internal structure of the mixing valve body 1 so that it has suction, and the foam liquid and air can be absorbed by the water pressure, so as to form foam inside and be sprayed out.

[0030] See also Figure 3 , 4 As shown in Figure 5, the contraction and extension component also includes an extension tube 9, which is slidably sleeved on the outer side of the water inlet pipe 4. The end of the extension tube 9 is fixedly connected to the extension interface 8. The end of the water inlet pipe 4 is fixedly connected with a sealing ring 13, the sealing ring 13 is slidably connected to the inner wall of the extension tube 9, the inner wall of the extension tube 9 is fixedly connected with a sealing gasket 14, the sealing gasket 14 is slidably connected to the water inlet pipe 4, the outer side of the water inlet pipe 4 is sleeved with an extrusion threaded sleeve 12 for extruding the extension tube 9, the outer side of the water inlet pipe 4 is provided with an external thread 11, the inside of the extrusion threaded sleeve 12 is fixedly connected with an internal threaded ring 10 that cooperates with the external thread 11, and the outer side of the water inlet pipe 4 is fixedly connected with a limiting ring 15 for limiting the separation of the extrusion threaded sleeve 12 from the water inlet pipe 4.

[0031] It should be noted that, in the present invention, the outer side of the water outlet pipe 5 is painted with corresponding water and inserted into the water outlet pipe for connection, and glue is applied to the outer side of the extension interface 8. According to the spacing between the pipes installed at both ends, the extension interface 8 drives the extension pipe 9 to slide toward one end of the water inlet pipe 4. When the extension interface 8 is connected to the water inlet pipe, the extrusion threaded sleeve 12 is rotated so that the extrusion threaded sleeve 12 and the water inlet pipe 4 move toward the end away from the mixing valve body 1 under the action of the thread, and the extrusion threaded sleeve 12 squeezes the extension pipe 9. The extension interface 8 squeezes the extension pipe 9 into the corresponding pipe to complete the connection with the water pipe.
