Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are used in a broad sense, and for example, "connected," may be fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediate medium, or connected between two elements.

Referring to fig. 1 to 9, the present invention provides a foam generating device for a toilet, including: the foaming agent mixing device comprises a water inlet waterway 1, a foaming agent stock solution inlet pipeline 2, a mixing cavity 3, a foaming head 4 and an air inlet pipeline 5;

the mixing cavity 3 is provided with a liquid inlet communicated with the water inlet waterway 1 and the foaming agent stock solution inlet pipeline 2 respectively, and a liquid outlet 311 communicated with the foaming head 4; the foaming head 4 is also provided with an air inlet 431 communicated with the air inlet pipeline 5; the air inlets 431 are circumferentially spaced along the side wall of the foaming head 4.

When the foaming agent is used, foaming agent stock solution and tap water respectively enter the mixing cavity 3 through the water inlet channel 1 and the foaming agent stock solution inlet pipeline 2 to be mixed, the mixed diluent enters the foaming head 4 through the liquid outlet 311 to be mixed with gas to form bubbles, and then the bubbles are discharged into a closestool to quickly cover a water seal; the functions of splash prevention and deodorization are achieved.

If a large amount of diluted blowing agent enters the foaming head 4 at the same time, the diluted blowing agent is not sufficiently mixed with the gas, and thus all of the diluted blowing agent cannot be uniformly foamed. In order to solve this problem, the foaming head 4 has an opening 411 communicating with the liquid outlet 311, and the extending direction of the air inlet 431 is perpendicular to the extending direction of the opening 411.

Further, the foaming head 4 includes a foaming head body 41, a foaming head end cap 42 and a foaming head inner core 43; the foaming head inner core 43 is arranged in the foaming head body 41, one end of the foaming head end cover 42 is inserted into the foaming head body 41, and the other end is exposed out of the foaming head body 41. Wherein, the end of the foaming head body 41 far away from the foaming head end cover 42 is provided with the opening 411, and the foaming head inner core 43 is arranged between the opening 411 and the foaming head end cover 42.

The inner core 43 of the foaming head is provided with a shunting hole 432 near the opening 411, and the diluted foaming agent flowing out of the mixing cavity 3 is cut into a plurality of independent diluted foaming agents through the shunting hole 432 and enters the inner cavity of the foaming head 4. Therefore, each part of the diluted foaming agent independently enters the inner cavity, and each part of the diluted foaming agent can be uniformly mixed with gas.

In this embodiment, the end cap 42 of the foaming head is provided with a foam outlet 421, and a screen 422 is provided between the foaming head 42 and the inner core 43 of the foaming head, for dividing the foam formed in the inner cavity of the foaming head 4 into small bubbles and discharging the small bubbles.

In order to allow gas to enter the foaming head inner core 43 and mix with the diluted foaming agent, the gas inlets 431 are arranged at intervals along the circumferential direction on the side wall of the foaming head inner core 43, the foaming head body 41 is provided with a channel 412 communicated with the gas inlet pipeline 5, and the other end of the channel 412 is communicated with the gas inlets 431. The air inlet 431 is disposed at a position between the opening 411 and the bubble outlet 421.

In this embodiment, the distance between the air inlet 431 and the screen 422 is 7-10 mm. This allows sufficient contact between the gas and the dilute blowing agent to produce a large number of bubbles before the dilute blowing agent reaches the screen 422.

In this embodiment, for the convenience of the initial mixing of tap water and the foaming agent stoste in mixing chamber 3, the contained angle between water inlet waterway 1 and foaming agent stoste liquid inlet pipeline 2 is the acute angle.

In order to avoid the foaming agent from flowing back to the water inlet waterway 1 and the foaming agent stock solution inlet pipeline 2 after dilution,

check valves

11 and 21 are respectively arranged in the water inlet waterway 1 and the foaming agent stock solution inlet pipeline 2

Finally, in order to allow the foaming agent and the tap water to be sufficiently mixed in the mixing chamber 3, a spiral mixing channel 321 communicating with the liquid outlet 311 is provided in the mixing chamber 3. Thus, the foaming agent and tap water are mixed and then flow into the spiral mixing channel 321 to form a vortex, so that the foaming agent and tap water are mixed more uniformly.

In particular, the mixing chamber 3 comprises a mixing chamber upper cover 31, a mixing chamber inner core 32 and a mixing chamber lower cover 33. The lower end of the mixing cavity upper cover 31 is covered on the outer side of the upper end of the mixing cavity inner core 32, and the upper end of the mixing cavity lower cover 33 is inserted into the lower end of the mixing cavity 3 inner core. The upper end of mixing chamber inner core 32 is provided with spiral mixing channel 321, and mixing chamber lower cover 33 communicates with water inlet 1 way, foamer stoste inlet conduit 2 respectively.

The foam generating device can be applied to other devices needing to generate foam besides the toilet bowl.

The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the technical scope of the present invention by replacing or changing the technical solution and the improvement concept of the present invention with equivalents and modifications within the technical scope of the present invention.
