Description

Technical field:

[0002] At present, some smart toilets are equipped with a bubble generating device, which outputs bubbles into the toilet, and the bubbles are suspended on the water cover, thereby achieving the effect of splash prevention, isolation and odor prevention.

[0003] For example, a Chinese invention patent discloses an intelligent toilet cleaning device and a control method thereof (authorization announcement number is CN105714900 B, and the authorization announcement date is 2018.01.12), including a foam generating device and a foam spraying device, wherein the foam generating device includes a liquid storage tank, a water inlet, a liquid suction pump, and a foaming stone. The liquid inlet of the liquid suction pump is connected to the inner cavity of the liquid storage tank through a conduit and the liquid outlet of the liquid storage tank, and the liquid outlet of the liquid suction pump is connected to the liquid inlet on the foaming box through a conduit. The water inlet is located on one side of the liquid inlet on the foaming box, and the foaming stone is located in front of the liquid inlet on the foaming box. When foaming is required, the liquid suction pump transports the foaming liquid in the liquid storage tank to the foaming box, and the water inlet supplies water to the foaming box. After foaming, the foam spraying device sprays foam into the toilet.

[0004] The above structure has the following defects: after a period of time when the conduit connecting the liquid storage tank and the suction pump stops conveying the foaming liquid, the foaming liquid remaining in the conduit will dry up, causing the conduit to be blocked, resulting in a large amount of foaming liquid used each time foaming is performed and a poor foaming effect. Summary of the invention:

[0005] The object of the present invention is to provide a foaming device for an intelligent toilet and an intelligent toilet which can reduce the amount of foaming liquid used and further improve the foaming effect.

Specific implementation method:

[0027] The present invention is further described below with reference to specific embodiments. Figure 1 —8:

[0028] One of the purposes of the present invention is to provide a foaming device for an intelligent toilet, comprising a liquid adding tank 1, an air pump 2, a foaming box 6 and a nozzle 7. The liquid adding tank 1 is provided with a foaming liquid capable of generating foam, such as detergent. The liquid adding tank 1 is provided with a liquid outlet 3, a one-way valve is provided at the liquid outlet 3, the liquid outlet 3 is respectively connected to a water inlet pipeline 4 and a water inlet of a liquid pump 5, the water outlet of the liquid pump 5 is connected to an inlet of the foaming box 6, the outlet of the foaming box 6 is connected to the nozzle 7, and the air pump 2 is connected to the foaming box 6. The nozzle 7 of the present invention is a rotating nozzle. The water inlet pipeline 4 is connected to a tap water pipe.

[0029] Working principle of the present invention:

[0030] When foaming is required, the liquid pump 5 operates to open the one-way valve to extract the foaming liquid in the liquid tank 1, and at the same time, the water inlet pipe 4 supplies water, and the mixture of the foaming liquid and water is transported to the foaming box 6 through the liquid pump 5 for foaming until foam is generated, and the air pump 2 operates to press the foam in the foaming box 6 out of the foaming box 6 and spray it to the corresponding position on the toilet through the nozzle 7. The actions of the liquid pump 5, the air pump 2, the foaming box 6, and the nozzle 7 are all controlled by the control unit on the smart toilet.

[0031] In the present invention, the liquid outlet 3 is connected to the water inlet of the liquid pump 5 through a first pipeline 8, the water outlet of the liquid pump 5 is connected to the inlet of the bubble box 6 through a second pipeline 9, the outlet of the bubble box 6 and the nozzle 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 simultaneously, after completing one foaming and foam spraying action, the amount of foaming liquid remaining in the first pipeline 8 connecting the liquid adding tank 1 and the liquid suction pump 5 is extremely small. When the foaming function is used after a period of time, the first pipeline 8 will not be blocked, which greatly improves the quality and service life of the foaming device.

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

[0034] like Figure 5 , 6 As shown in Figures 7 and 8, the liquid outlet 3 of the liquid adding tank 1 includes a cylindrical protrusion 13 arranged on the outer wall of the liquid adding tank 1, and a plurality of through holes connected to the inner cavity of the liquid adding tank 1 are arranged on the outer wall of the liquid adding tank 1 located inside the cylindrical protrusion 13, a three-way joint 12 is arranged at the outer end of the cylindrical protrusion 13, and a one-way valve is arranged inside the cylindrical protrusion 13.

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

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

[0037] like Figure 8 As shown, the three-way joint 12 includes a first joint 17 inserted in 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. A second joint 18 and a third joint 19 are connected to the first joint 17. The outer end of the first joint 17 is provided with a mounting ear 14 for mounting it on the liquid filling tank 1.

[0038] like Figure 1-3 As shown, the air pump 2 and the liquid pump 5 are arranged in the same housing and connected with the foaming box 6, which is easy to install.

[0039] Another object of the present invention is to provide an intelligent toilet, comprising the above-mentioned foaming device of the intelligent toilet.

[0040] The above 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, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the protection scope of the present invention.
