Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 A foaming device for a smart toilet includes an L-shaped housing 1, an annular bracket 2 fixedly connected to the top surface of the L-shaped housing 1, a micro pump 3 embedded inside the annular bracket 2, a suction tube 4 inserted into the suction end of the micro pump 3, and a delivery tube 5 inserted into the discharge end of the micro pump 3, a foaming component 6 inserted into one end of the delivery tube 5, a foam spraying tube 7 inserted into the outlet of the foaming component 6, and a storage bottle 8 threadedly connected to the bottom of the L-shaped housing 1. The foaming assembly 6 includes an outer cylinder 61, a liquid inlet pipe 62 fixedly connected to the outer surface of the outer cylinder 61, a venturi tube 63 fixedly connected to one end of the liquid inlet pipe 62, an annular foaming plate 64 inserted into the top of the venturi tube 63, an end cap 65 threadedly connected to the top of the outer cylinder 61, a one-way air valve 66 threadedly connected to the top surface of the end cap 65, and a bubble outlet pipe 67 fixedly connected to the top surface of the end cap 65.

[0018] Specifically, two hooks 9 are fixedly connected to the side wall of the L-shaped shell 1. The hooks 9 are made of metal and have a thickness of 1-2mm.

[0019] The advantage is that by setting two hanging ears 9, it can be hung on the outer wall of the toilet tank, which can fix the L-shaped shell 1, and thus connect the entire foaming device to the toilet. Furthermore, by placing the foaming device externally, the capacity of the foaming liquid stored in the liquid storage bottle 8 can be easily observed at any time. The liquid storage bottle 8 is also connected to the screw tube at the bottom of the L-shaped shell 1, which makes it easy to disassemble the liquid storage bottle 8 and refill it with foaming liquid in a timely manner.

[0020] Specifically, a battery compartment 10 is fixedly connected to the top surface of the L-shaped housing 1, and a touch switch 11 is fixed to the outside of the L-shaped housing 1.

[0021] The advantage is that batteries can be placed in the battery compartment 10, and the bottom of the battery compartment 10 is connected to the L-shaped housing 1. The wiring inside the L-shaped housing 1 allows the batteries in the battery compartment 10 to provide power to the micro pump 3 and the touch switch 11. The micro pump 3 can be started immediately by touching the touch switch 11.

[0022] Specifically, the suction tube 4 passes through the L-shaped housing 1 and is inserted into the inside of the storage bottle 8. The storage bottle 8 is made of transparent material. A screw tube is fixedly connected to the bottom of the L-shaped housing 1, and the internal thread of the screw tube is connected to the storage bottle 8.

[0023] The advantages are that the foam spray pipe 7 can be placed in the flushing tank of the toilet. When the foam is discharged from the foam outlet pipe 67, it will enter the foam spray pipe 7 and finally be discharged from multiple foam outlets 71. This can evenly form a "foam shield" on the inner wall of the toilet. This dense foam can effectively prevent sewage from splashing when feces fall, avoid contamination of the user's body, and improve the cleanliness and comfort of use. Secondly, the foam can absorb odors in the bathroom, reduce the spread of odors, and keep the air fresh.

[0024] Specifically, the end of the delivery pipe 5 away from the micro pump 3 is connected to the liquid inlet pipe 62, and the top of the bubble outlet pipe 67 is connected to the foam spray pipe 7. Multiple foam outlets 71 are provided on the outer wall of the foam spray pipe 7.

[0025] Specifically, the end of the liquid inlet pipe 62 furthest from the delivery pipe 5 is tangentially connected to the outer circumferential surface of the venturi tube 63.

[0026] The advantage is that the micro pump 3 draws foaming liquid from the storage bottle 8 and sends it into the liquid inlet pipe 62 through the suction pipe 4 and the delivery pipe 5. The liquid inlet pipe 62 is tangentially connected to the venturi tube 63, so that the foaming liquid generates negative pressure when it flows through the venturi tube 63 at high speed. With the help of the one-way air valve 66 on the end cap 65, air is drawn in. After the gas-liquid mixture is initially mixed in the venturi tube 63, it impacts the annular foaming plate 64 upward. The bubbles are further cut and dispersed through the fine pores of the foaming plate to form a large number of micro bubbles. Subsequently, the mixed foam enters the chamber formed by the outer cylinder 61 and the end cap 65 under pressure, and is transported to the foam spraying pipe 7 through the foam outlet pipe 67. Finally, it is evenly sprayed out from multiple foam outlets 71. The whole process ensures the density of the foam through the gas-liquid mixing of the venturi tube 63, the bubble refinement of the annular foaming plate 64, and the dispersion and release of multiple outlets.

[0027] In use, the entire foaming device is hung on the outer wall of the toilet tank using the two hooks 9 on the side wall of the L-shaped housing 1, thus securing the device to the toilet. Next, check the capacity of the foaming liquid in the storage bottle 8. If insufficient, unscrew the transparent storage bottle 8, fill it with foaming liquid, and then connect it to the threaded tube at the bottom of the L-shaped housing 1 to replenish the foaming liquid. Insert batteries into the battery compartment 10 to power the micro pump 3 and the touch switch 11. Place the foam spray pipe 7 into the toilet's flushing basin, ensuring that its multiple foam outlets 71 correspond to the inner wall of the toilet. Touch the touch switch 11 to activate the micro pump 3, which draws in the foam. Pipe 4 draws foaming liquid from storage bottle 8 and sends it to liquid inlet pipe 62 of foaming component 6 via delivery pipe 5; 6. The foaming liquid enters Venturi tube 63 through liquid inlet pipe 62, generates negative pressure due to high-speed flow, and draws in air in conjunction with one-way air valve 66 on end cap 65. After initial mixing in Venturi tube 63, the gas-liquid mixture impacts the annular foaming plate 64 upwards, and is cut and refined through fine pores to form a large number of tiny bubbles; the refined foam enters the chamber formed by outer cylinder 61 and end cap 65 under pressure, and then enters foam spraying pipe 7 through bubble outlet pipe 67, and is finally sprayed evenly from multiple bubble outlets 71 to form a "foam shield" on the inner wall of the toilet.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
