[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention.

[0027] Reference Figure 1 As shown, a bathing liquid mixing and foaming device includes a first pipe 1 for conveying tap water and a second pipe 2 for conveying bath liquid. A pressure reducing device 3 and a foaming device 4 are installed on the first pipe 1 in sequence along the water flow direction. The outlet end of the second pipe 2 is connected to a connecting pipe between the pressure reducing device 3 and the foaming device 4. The pressure reducing device 3 is used to control the conveying pressure of the tap water, and the foaming device 4 is used to agitate the mixture of bath liquid and tap water into foam for output. The bath liquid is shampoo and / or shower gel.

[0028] The pressure-reducing on / off device 3 consists of a pressure-reducing valve 3-1 and an on / off valve 3-2 connected in sequence. The on / off valve is a solenoid valve or an electric valve. By setting the pressure-reducing valve 3-1, the tap water supply pressure of the mixing and foaming device can be effectively reduced, thereby ensuring the subsequent mixing and foaming effect. The on / off valve 3-2 is used to control the on / off of tap water so as to cut off the tap water supply when bathing is stopped.

[0029] The foaming device includes an air pump and a foam generator. A mixture of bath liquid and tap water enters the foam generator to create foam, and the air pump supplies air to the foam generator. The structure of the foam generator is as follows: Figure 2 As shown, the device includes a conical foamed inner cavity 4-1. The small end inlet of the conical foamed inner cavity 4-1 is connected to an air inlet 4-2 and a liquid inlet 4-3. The air inlet 4-2 is connected to an air pump, and the liquid inlet 4-3 is connected to the outlet of a pressure reducing on / off device 3. The large end outlet of the conical foamed inner cavity 4-1 is equipped with a conical mesh 4-4. During operation, the water vapor mixture generates a rotating atomized airflow within the conical foamed inner cavity 4-1 under the action of flow impact force. The rotating atomized airflow produces abundant foam when passing through the conical mesh 4-4. To facilitate the installation and maintenance of the conical mesh 4-4, the conical foamed inner cavity 4-1 is composed of two cylindrical parts connected by threads. The periphery of the conical mesh 4-4 is locked and fixed between the left cylindrical part 4-5 and the right cylindrical part 4-6. A sealing gasket 4-7 is also provided between the left cylindrical part 4-5 and the right cylindrical part 4-6 to ensure the sealing of the connection.
