Embodiment 1

[0035] Figure 4It is a structural schematic diagram of Embodiment 1 of the foam generating device of the present invention in the non-conducting state of the first solenoid valve 1; Figure 5 It is an axial sectional view of the detergent supply part of Embodiment 1 of the foam generating device of the present invention; Image 6 yes Figure 5 Enlarged view of Part I of ; Figure 7 It is a structural schematic diagram of Embodiment 1 of the foam generating device of the present invention in the conduction state of the first solenoid valve 1 .

[0036] Such as Figure 4 to Figure 6 As shown, the foam generating device 50 includes: a first solenoid valve 1 connected to a tap water source, a detergent supply part 2, a detergent box 3, a foam spraying part 5, and a control part 6 (not shown). The first solenoid valve 1 is generally a pilot solenoid valve.

[0037] The detergent supply part 2 includes a cylinder 21 with a hollow inner cavity. The inner cavity of the cylinder ...

Embodiment 2

[0043] Compared with Embodiment 1, the present embodiment mainly relates to the modification of the spray foam part 5, such as Figure 8 As shown, the inner cavity of the pipe body 51 is sequentially composed of a suction chamber 515, a throat 514 with a reduced diameter and a trumpet-shaped mixing chamber 511, and a nozzle 56 coaxial with the throat 514 is also provided in the suction chamber. Throat 514 is provided with a gap. The front surface of the suction chamber 515 is provided with a first liquid inlet 512 connected to the drain port 232 and a second liquid inlet 513 connected to the detergent outlet 251 . Similarly, the rear end of the mixing chamber 511 is provided with a foaming film 53 with a large number of fine mesh structures, and is pressed and limited by the foam outlet cover 54 fixedly connected with the pipe body 51 . A check valve 52 is arranged at the second liquid inlet 513, preferably a duckbill check valve, allowing fluid to pass through from the deter...

Abstract

The invention relates to a foam generating device. The device comprises a first electromagnetic valve for supplying washing water and a detergent box for supplying a detergent. The device further comprises: a detergent supply part which comprises a cylinder and an axially-movable piston assembly arranged in the cavity of the cylinder, wherein the piston assembly and an inner cavity isolation plate of the cylinder form an opening and closing function to control the conduction or isolation of the detergent; and a foam spraying part which is provided with a pipe body which is hollow inside and forms a mixing cavity, wherein the washing water and the detergent from the detergent supply part are mixed in the mixing cavity and then sprayed out from a foam spraying opening in the rear end of the pipe body to form foam. The foam generating device of the structure utilizes water source pressure of flushing water to complete automatic introduction of the detergent, does not adopt electric appliance elements such as an electric pump, and is low in cost and capable of reducing power consumption.

Description

technical field [0001] The invention relates to a foam generating device and an intelligent toilet using the device. IPC classifications are E03D 9 / 02, E03D 11 / 02, B01F 3 / 04, and E03C 1 / 046. Background technique [0002] The prior art foam generating device proposes a method in which a device called an ejector that shrinks the path diameter of a portion is provided on a flush water flow path where flush water flows. Air and detergent are supplied to the ejector from the outside. When the flushing water flows into the ejector, a negative pressure is generated in the ejector, and air is drawn into the ejector by the ejection effect, and the flushing water, air, and detergent are mixed to generate foam and flow into the urinal. [0003] Its typical structure can refer to the Chinese patent whose publication number is CN107923168B. Its detergent is pumped into the injector by an electric pump and mixed. The structure is complex and consumes electricity. [0004] For other rele...
