Embodiment 1

[0035] Figure 4It is a schematic structural 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 cross-sectional view of the detergent supply part of the foam generating device in Example 1 of the present invention; Image 6 Yes Figure 5 An enlarged view of Part I; Figure 7 It is a schematic structural diagram of Embodiment 1 of the foam generating device of the present invention in the conducting state of the first solenoid valve 1 .

[0036] like Figure 4 to Figure 6 As shown, the foam generator 50 includes a first solenoid valve 1 connected to a tap water source, a detergent supply unit 2, a detergent box 3, a foam spray unit 5, and a control unit 6 (not shown). The first solenoid valve 1 is generally a pilot solenoid valve.

[0037] The detergent supply part 2 includes a cylindrical body 21 with a hollow inner cavity, the inner cavity of the cylindrical bo...

Embodiment 2

[0043] Compared with Embodiment 1, this embodiment mainly involves the modification of the foam spraying part 5, such as Figure 8 As shown, the inner cavity of the tube body 51 is sequentially composed of a suction cavity 515, a throat portion 514 with a reduced diameter, and a trumpet-shaped mixing cavity 511, and a nozzle 56 coaxial with the throat portion 514 is also arranged in the suction cavity. Throat 514 is provided with a gap. The front surface of the suction cavity 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 surface of the mixing chamber 511 is provided with a foaming membrane 53 having a large number of fine mesh structures, and is pressed and limited by the foam ejection 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, to allow flui...

Abstract

A foam generating device, comprising a first electromagnetic valve for supplying flushing water, a detergent box for supplying detergent, and a detergent supply part, including a cylinder body and an axially movable piston assembly provided in the inner chamber of the cylinder body , the piston assembly forms an opening and closing function with the isolation plate in the inner cavity of the cylinder to control the conduction or isolation of the detergent; and the foam spraying part has a hollow tube inside to form a mixing chamber, and the flushing water and detergent from the detergent supply part After mixing in the mixing chamber, the foam is sprayed out from the foam outlet at the rear end of the pipe body to form foam. The foam generating device of this structure uses the water source pressure of flushing water to complete the automatic introduction of detergent, does not use electrical components such as electric pumps, and has low cost and reduced power consumption.

Description

technical field [0001] The present invention relates to a foam generating device and an intelligent toilet using the same. Background technique [0002] The prior art foam generating device proposes a method of disposing a device called an ejector, which narrows the diameter of the path of the flushing water, on the flushing water flow path in which the flushing water flows. Air and detergent are supplied to the ejector from the outside. When the flushing water flows into the ejector, the ejection effect becomes negative pressure in the ejector, air is introduced into the ejector through the ejection effect, and the flushing water, air and detergent are mixed to generate foam and flow into the toilet. [0003] For its typical structure, please refer to the Chinese Patent Publication No. CN107923168B. The detergent is pumped into the injector by an electric pump for mixing, which is complicated in structure and consumes electricity. [0004] For other relevant terms and com...
