Foaming device of intelligent closestool and intelligent closestool

[0027]The present invention will be further described below with specific examples, seefigure 1 -8:

[0028]One of the objectives of the present invention is to provide a foaming device for a smart toilet, which includes a filling tank 1, an air pump 2, a foaming box 6 and a spray head 7. The filling tank 1 is provided with a foaming liquid capable of generating foam, such as Dishwashing liquid etc. The liquid filling tank 1 is provided with a liquid outlet 3, the liquid outlet 3 is provided with a one-way valve, and the liquid outlet 3 is respectively connected with the water inlet pipe 4 and the water inlet of the liquid suction pump 5 to pump The water outlet of the liquid pump 5 is connected with the inlet of the bubbling box 6, the outlet of the bubbling box 6 is connected with the spray head 7, and the air pump 2 is connected with the bubbling box 6. The spray head 7 of the present invention is a rotary spray head. The water inlet pipe 4 is connected with the tap water pipe.

[0029]The working principle of the present invention:

[0030]When foaming is required, the suction pump 5 works and opens the check valve to pump out the foaming liquid in the liquid filling tank 1, while the water inlet pipe 4 supplies water, and the mixture of foaming liquid and water is delivered to the foaming liquid through the liquid suction pump 5. The bubble box 6 is bubbled to produce bubbles, and the air pump 2 works to press the bubble in the bubble box 6 out of the bubble box 6 to spray the corresponding position on the toilet through the nozzle 7. The actions of the liquid suction pump 5, the air pump 2, the bubble box 6, and the spray head 7 are all controlled by the control unit on the smart toilet.

[0031]In the present invention, the liquid outlet 3 and the water inlet of the suction pump 5 are connected by a first pipeline 8, and the water outlet of the suction pump 5 and the inlet of the bubbling box 6 are connected by a second pipeline. 9 is connected, the outlet of the bubble box 6 and the spray head 7 are connected through a third pipeline 10, and the air pump 2 and the bubble box 5 are connected through a fourth pipeline 11.

[0032]Since the foaming liquid and water of the present invention are transported at the same time, after completing a foaming and foam spraying action, the remaining foaming liquid in the first pipe 8 connecting the liquid filling tank 1 and the liquid suction pump 5 The quantity is very small, and the foaming function is used after a period of time, and the first pipeline 8 will not be blocked, which greatly improves the quality and service life of the foaming device.

[0033]In order to facilitate the connection, a three-way joint 12 is provided at the liquid outlet 3, and the three-way joint 12 is connected to the liquid outlet 3, the water inlet pipe 4 and the liquid pump 5 respectively. Specifically, it is the first pipeline 8 connecting the filling tank 1 and the suction pump 5.

[0034]Such asFigure 5 ,67. As shown in 7, the liquid outlet 3 of the liquid filling tank 1 includes a cylindrical protrusion 13 arranged on the outer side wall of the liquid filling box 1, and the outer side wall of the liquid filling box 1 located in the cylindrical protrusion 13 is provided with Several through holes communicating with the inner cavity of the filling tank 1 are provided with a three-way joint 12 at the outer end of the cylindrical protrusion 13, and a one-way valve is provided in the cylindrical protrusion 13.

[0035]In the present invention, the one-way valve is a diaphragm. When the liquid suction pump 5 is not working, the through hole is blocked by the diaphragm, and the foaming liquid in the liquid adding tank 1 will not flow out. When the liquid suction pump 5 is working, the diaphragm is sucked outward, and the bubbling liquid in the liquid filling tank 1 enters the first pipeline 8.

[0036]Such asImage 6 ,7As shown, the plurality of through holes include a circular hole 15 and arc-shaped holes 16 circumferentially distributed outside the circular hole 15. The shape distribution of several through holes can be set according to actual conditions, such as irregular distribution of several round holes or rectangular distribution of several round holes.

[0037]Such asFigure 8 As shown, the three-way joint 12 includes a first joint 17 inserted into the cylindrical protrusion 13. In order to increase the sealing performance, a sealing ring is arranged between the first joint 17 and the cylindrical protrusion 13. The second connector 18 and the third connector 19 communicating with the first connector 17 are provided with mounting ears 14 for mounting them on the filling tank 1 at the outer end of the first connector 17.

[0038]Such asFigure 1-3As shown, the air pump 2 and the liquid suction pump 5 are arranged in the same housing and connected to the bubbling box 6 for easy installation.

[0039]Another object of the present invention is to provide a smart toilet including the above-mentioned foaming device for the smart toilet.

[0040]The foregoing embodiment is only one of the preferred embodiments of the present invention, and is not intended to limit the scope of implementation of the present invention. Therefore: all equivalent changes made in accordance with the shape, structure, and principle of the present invention should be covered by the present invention Within the scope of protection.
