[0006] The air hole is opened on the water-gas mixing tube and allows the gas to enter the water-gas mixing tube; the gas entering the water-gas mixing tube and the liquid vortex coming out of the second channel section are fully mixed in the water-gas mixing tube and then discharged.

[0007] The advantages or beneficial effects of the above foaming device include at least:

[0008] A first channel section and a second channel section are arranged in the water-gas mixing tube of the foaming device. The water-gas mixing tube has a first flow channel for passing liquid.

[0030] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0031] A foaming device, the device comprises: a water-gas mixing tube 10, the water-gas mixing tube 10 has a first flow channel 11 for passing liquid, the first flow channel 11 comprises a first channel section 111 and a second channel section 112 which are interconnected, the connection between the first channel section 111 and the second channel section 112 is defined as a first liquid inlet 14, and the first liquid inlet 14 is offset relative to the axial section of the second channel section 112, so that the liquid enters the second channel section 112 from the first channel section 111 to form a vortex, specifically, the first channel section 111 is connected to the second channel section 112 in the form of a tangent of a circle, the circle is the cross section of the second channel section 112, the tangent is the axis of the first channel section 111, and there is a preset angle α between the axis of the first channel section 111 and the axis of the second channel section 112, so that when the liquid enters from the first channel section 111 to the second channel section 112, a rotating vortex can be formed, such as Figure 6 and Figure 8 As shown, when the liquid forms a rotating vortex, a large amount of water splashes, thereby increasing the contact area with the air, so that the liquid is fully in contact with the air, and the foaming effect of the bubble cleanser is enhanced. The liquid includes a foam cleanser.

[0032] Based on the above structure, the angle between the axis of the first channel section (111) and the axis of the second channel section (112) is defined as α, wherein 0°<α<180°, and the preferred value range of α is between 60° and 120°. Regardless of the angle, it falls within the protection scope of the present application, and the aperture of the first channel section 111 gradually decreases as it approaches the second channel section 112, and the cross-section of the first liquid inlet is larger than the cross-section of the second channel section 112, which can further increase the water pressure.

[0033] Based on the above structure, the water-gas mixing tube 10 further has a first inclined surface 13 and a second inclined surface 14 between the first channel section 111 and the second channel section 112. The first inclined surface 13 and the second inclined surface 14 are directed toward the water inlet direction of the first flow channel 11. Fig.14 As shown, the liquid can be guided to form a vortex when the first flow channel 11 enters the first channel section 111 and the second channel section 112, and can further assist in the mold opening process of the water-gas mixing tube 10.

[0034] The device further comprises an air hole 12, which is provided on the water-gas mixing tube 10 and is used to allow the gas to enter the water-gas mixing tube 10 and mix the gas with the liquid discharged from the second channel section 112;

[0035] Based on the above structure, the water-gas mixing tube 10 also has a accommodating space 15, and the accommodating space 15 is connected to the outside through the air hole 12. The device further includes: a plugging member 16, which is movably installed in the accommodating space 15 and is used to close or open the air hole 12; the size of the plugging member 16 is larger than the size of the air hole 12, and the part of the water-gas mixing tube 10 in the accommodating space 15 also has a first protrusion 151, and the top of the first protrusion 151 conflicts with the plugging member 16, so that there is a fixed distance between the plugging member 16 and the bottom of the accommodating space 15. When the water flows from the accommodating space 15, the water will first flow into the distance between the plugging member 16 and the bottom of the accommodating space 15, thereby pushing up the plugging member 16, such as Figure 6-7 As shown, to prevent liquid from flowing out of the air hole 12

[0036] The embodiment of the utility model also provides a cleaning device, comprising: the above-mentioned foaming device, further comprising: a water spray pipe 30, installed on the toilet, the water spray pipe 30 is used to flush the toilet; a mounting pipe 20, one end of the mounting pipe 20 is installed on the water-gas mixing pipe 10, and the other end is installed on the water spray pipe 30, the mounting pipe 20 is connected to the water spray pipe 30, and the first flow channel 11 is connected to the mounting pipe 20; the water spray pipe 30 is further used to spray liquid into the toilet, so there is no need to add an additional nozzle specifically for spraying cleaning liquid, only one water spray pipe 30 is needed.

[0037] The portion between the mounting pipe 20 and the water-gas mixing pipe 10 also has a second protrusion 21, and the water inlet of the mounting pipe 20 also has an annular recess 22, so that there is a fixed distance between the sealing member 16 and the annular recess 22, so that air can flow into the mounting pipe 20 from this distance.

[0038] Furthermore, the mounting tube 20 can move back and forth along the axial direction of the main water pipe, and a positioning knob 32 is screwed onto the water spray pipe 30 for positioning the mounting tube 20 on the water spray pipe 30. Specifically, the water spray pipe 30 has a positioning ring, and when the water spray pipe 30 is installed on the toilet, the side wall of the toilet can be clamped between the positioning ring and the mounting tube 20, and it can also adapt to toilet side walls of different thicknesses.

[0039] Based on the above structure, a nozzle 31 is further provided at one end of the water spray pipe 30 away from the mounting pipe 20; the portion between the nozzle 31 and the water spray pipe 30 is an outer arc structure, and the portion between the water spray pipe 30 and the nozzle 31 is an inner arc structure, and the outer arc shape is adapted to the inner arc shape so that the nozzle 31 can be rotatably clamped to the end of the water spray pipe 30. Compared with the prior art, there is no need to additionally install a nut for positioning the nozzle 31, which can reduce production costs.

[0040] In the description of the present disclosure, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure.
