As shown in fig. 1, 2, 3 and 4, the present embodiment provides a foaming device for a toilet, which can generate foam flowing into a toilet bowl cavity of the toilet, so that a foam shield is formed on a water sealing surface of the toilet bowl cavity. Specifically, this foaming device is provided with a liquid inlet passage 1, an injection hole 2, an air suction chamber 3, an air suction passage 4, and a foam outlet passage 7. Wherein, feed liquor passageway 1 is used for flowing in foaming agent and water after mixing, jet orifice 2 intercommunication feed liquor passageway 1 and chamber of breathing in 3, and the axis of feed liquor passageway 1 is not parallel to the axis of jet orifice 2, and the one end of breathing in passageway 4 and bubble outlet channel 7 communicates respectively in chamber of breathing in 3, and the other end of breathing in passageway 4 can communicate with outside air, and the other end of bubble outlet channel 7 is provided with the bubble outlet 8 that is linked together with just the chamber. In addition, the foaming device comprises a foaming net 5 arranged in front of the air suction cavity 3. In operation, liquid from the liquid inlet channel 1 can be re-injected into the air suction cavity 3 through the injection hole 2, and because the size of the injection hole 2 is smaller, the injection hole 2 can form a liquid beam which is rapidly injected into the air suction cavity 3, so that the air suction cavity 3 generates a Venturi effect, the air pressure of the air suction cavity 3 is smaller than the air pressure of the air suction channel 4, the air suction cavity 3 can suck air from the air suction channel 4, the foaming agent and water from the liquid inlet channel 1 and the air from the air suction channel 4 are mixed, a large amount of foam can be generated when the mixed liquid and air pass through the foaming net 5, the foam is discharged along the foaming channel 7, and finally flows into the water sealing surface of the toilet bowl cavity from the foaming opening 8.
It should be noted that, as shown in fig. 4, since the axis of the liquid inlet channel 1 is not parallel to the axis of the injection hole 2, that is, the angle a in fig. 4 is not equal to 0 ° or 180 °, the fluid flowing into the injection hole 2 from the liquid inlet channel 1 will impact the corresponding hole wall, and the fluid will be in an oscillating state, so that the fluid flowing into the injection hole 2 has a tendency to move circumferentially, which is helpful for the fluid to be injected into the air suction cavity 3 from the injection hole 2, so that the caliber D of the end of the fluid beam is larger than the caliber C of the injection hole 2, and the scattered fluid beam can generate a stronger venturi effect in the air suction cavity 3, thereby facilitating better air suction from the air suction channel 4. In addition, the scattered liquid bundles can also allow more thorough mixing of the mixed liquid and air, which is advantageous for generating more foam when passing through the bubble generating network 5.

This configuration of the guide surface 11 has the effect of guiding the liquid from the inlet channel 1 to the injection hole 2, and greatly reduces the kinetic energy loss of the fluid therein, so that the liquid beam emitted from the injection hole 2 has a greater velocity, resulting in a stronger venturi effect. In other embodiments, the guiding surface 11 may be an arc surface or other transitional curved surfaces, which serves to guide the liquid from the liquid inlet channel 1 to the injection hole 2, and will not be described in detail.
In addition, as shown in fig. 4, in the present embodiment, the injection hole 2 is a through hole with a constant caliber and a straight central axis, and the through hole with a straight central axis can reduce kinetic energy loss, so that the liquid injected from the injection hole 2 has a faster speed. In other embodiments, the injection hole 2 may be a through hole with a diameter that increases toward the air suction cavity 3 and a central axis is a straight line, for example, the injection hole 2 may be in a horn shape, a bell shape, or a thin waist shape, etc., and the injection hole 2 with such a structure may allow the end of the liquid beam emitted from the injection hole 2 to have a larger diameter, so as to further enhance the venturi effect of the air suction cavity 3.
In addition, in this embodiment, the foaming device may be provided with one or more injection holes 2, and the section of the injection holes 2 may be various shapes, such as a circle, an ellipse, a square, a trapezoid, or a polygon, which will not be described herein.

It should be noted that, in other embodiments, the foaming device may also include other numbers of foaming nets 5 and corresponding spacer rings 6, which are not described herein.
As shown in fig. 3, in the present embodiment, the foaming device is further provided with a water outlet channel 9, a water outlet 10 is provided at the end of the water outlet channel 9, and the water outlet channel 9 and the water outlet channel 7 are separately provided, and water from the water outlet channel 9 can be supplied to the toilet flushing toilet cavity. The structure can combine the foam outlet channel 7 for discharging foam with the water outlet channel 9 for discharging brush ring water, so that the toilet bowl has more concise pipeline arrangement.
As shown in fig. 5, 6 and 7, the present embodiment also provides a foaming device which is provided with not only a liquid inlet channel 1, an injection hole 2, an air suction cavity 3, an air suction channel 4, a foam outlet channel 7 and a water outlet channel 9, wherein the ends of the foam outlet channel 7 and the water outlet channel 9 are respectively provided with a foam outlet 8 and a water outlet 10. In addition, the foaming device is further provided with a switching valve group 12, the switching valve group 12 can switch and control the water supply channel 9 to supply water, and the switching valve group 12 belongs to the prior art in the field and is not described herein. The foaming device of the present embodiment, which is capable of injecting the liquid beam into the air suction cavity 3 through the injection hole 2, also enables the air suction cavity 3 to generate a venturi effect to form a negative pressure, and sucks air from the air suction channel 4, so as to mix the foaming agent, water and air to generate foam subsequently, and the specific working principle is the same as that of the previous embodiment, and will not be repeated here.
It should be noted that, as shown in fig. 6, in this embodiment, the injection hole 2 may be a through hole with a caliber that increases toward the direction of the air suction cavity 3 and the central axis is a straight line, and an included angle E is formed on two sides of the injection hole 2, so that the end of the liquid beam emitted from the injection hole 2 by the injection hole 2 with this structure has a larger caliber, which can further enhance the venturi effect of the air suction cavity 3, and make the air suction cavity 3 suck air from the air suction channel 4 better.
The present embodiment also provides a toilet (not shown), which includes a toilet seat and a foaming device, wherein the toilet seat is provided with a toilet cavity, the foaming device is any one of the foaming devices provided in the above embodiment, foam generated by the foaming device can be discharged into the toilet cavity, and a foam shield is formed on the water seal surface of the toilet cavity.
The foaming device and the closestool provided by the embodiment can enable the foaming device to generate foam without arranging a special air pump for supplying air to the foaming device. Specifically, the foaming device is characterized in that liquid from the liquid inlet channel 1 is injected into the air suction cavity 3 through the injection hole 2, and because the size of the injection hole 2 is small, a fast-moving liquid beam can be generated through the injection hole 2, so that the air suction cavity 3 generates a venturi effect, the air pressure of the air suction cavity 3 is smaller than the air pressure of the air suction channel 4, and the air suction cavity 3 can suck air from the air suction channel 4, and the liquid from the liquid inlet channel 1 and the air from the air suction channel 4 are mixed. In addition, because the axis of the liquid inlet channel 1 is not parallel to the axis of the injection hole 2, the fluid flowing into the injection hole 2 from the liquid inlet channel 1 can impact the corresponding hole wall, so that the fluid is in an agitating state, the fluid flowing into the injection hole 2 has a tendency to move circumferentially, thus being beneficial to generating scattered liquid beams in the process of injecting the fluid from the injection hole 2 into the air suction cavity 3, leading the caliber of the tail end of the liquid beams to be larger than the aperture of the injection hole 2, being capable of better accelerating the air flow in the air suction cavity 3, leading the air suction cavity 3 to generate stronger Venturi effect, and being convenient for better sucking the air from the air suction channel 4. In addition, the scattered liquid bundles can also allow more thorough mixing of the mixed liquid and air, which is advantageous for generating more foam when passing through the bubble generating network 5.
Compared with the prior art, the foaming device and the closestool can omit an air pump and an air passage and a control port matched with the air pump, so that the cost of the foaming device can be greatly reduced, more precious space can be made for the closestool, and the foaming device has good practicability.
