Smart toilets need to add other functions in addition to fulfilling basic functions to be more popular with users, such as sterilization of ceramic pool surfaces and odor isolation with foam shields. At present, smart toilets achieve both electrolyzed water sterilization of ceramic pool surfaces and ceramic water seal foam shield by spraying different nozzles to achieve these two functions. Achieving these two functions through different nozzles makes the module structure too complicated, occupies too much space in the smart toilet, and makes the overall structure difficult to lay out, resulting in poor actual use effect.

The first flow channel 41 is connected to the top opening and enters the working chamber 24 along the axial direction of the working chamber 24. The second flow channel 14 is connected to the side opening and enters the working chamber 24 along a direction tangent to the circumference or radial direction of the working chamber 24 to form rotating water in the working chamber 24.

[0031] In this embodiment, the first functional water is columnar water, and the second functional water is hollow dispersed particle water.

[0032] In this embodiment, the inner wall surface of the bottom of the working cavity 24 is spherical, the upper part of the working cavity 24 is cylindrical, and the side opening is located on the cylindrical cavity.

One end of the third liquid inlet channel 131 is connected to the first flow channel 41.

[0034] The third liquid inlet channel 131 is connected to the first flow channel 41. The water in the first liquid inlet channel 111 and the liquid in the third liquid inlet channel 131 are mixed through the first flow channel 41 and then sprayed out from the spray nozzle 21.

[0035] In this embodiment, the outer wall of the nozzle 20 is provided with a plurality of snap-fit ​​posts 22, and the housing 10 is provided with snap-fit ​​grooves 15 that mate with the snap-fit ​​posts 22. The snap-fit ​​grooves 15 include a through groove for the snap-fit ​​posts 22 to enter and a limiting groove for fixing the snap-fit ​​posts 22. After the snap-fit ​​posts 22 of the nozzle 20 are aligned with the through groove and inserted, they are rotated at a certain angle to make the snap-fit ​​posts 22 engage with the limiting groove to achieve fixed installation.

[0036] In this embodiment, the nozzle 20 is sleeved inside the housing 10, and a first sealing element is provided between the outer wall of the nozzle 20 and the inner wall of the housing 10. The side opening is located above the first sealing element.

[0037] The nozzle 20 has a first mounting groove 23 on its outer wall, and a first sealing ring 30 is provided in the first mounting groove 23. The first sealing ring 30 is interference-fitted with the inner wall of the housing 10.

[0038] The nozzle 20 described in this embodiment has a working chamber 24, which is connected to the water nozzle 21. The side wall of the working chamber 24 is provided with a flow hole 25, and the second flow channel 14 is connected to the working chamber 24.

[0039] In this embodiment, the upper part of the housing 10 is provided with a water distribution cavity 16 that communicates with the first liquid inlet connector 11, the top of the water inlet core 40 is sealed and connected to the water distribution cavity 16, and the upper part of the housing 10 is also provided with a third liquid inlet connector 13, which is provided with a third liquid inlet channel 131 that communicates with the water distribution cavity 16.

[0040] In this embodiment, the bottom of the water inlet core 40 is nested in the top of the working chamber 24, so that the first flow channel 41 is connected to the working chamber 24, and thus the first flow channel 41 is connected to the spray nozzle 21; the top of the water inlet core 40 is nested in the water distribution chamber 16, so that the first flow channel 41 is connected to the water distribution chamber 16, and thus the first liquid inlet channel 111 and the third liquid inlet channel 131 are both connected to the first flow channel 41.

[0041] In this embodiment, the outer wall of the water inlet core 40 is provided with a second mounting groove 42, and a second sealing ring 50 is provided in the second mounting groove 42. The second sealing ring 50 is interference-fitted with the inner wall of the water distribution chamber 16.

[0044] In this embodiment, the first liquid inlet channel 111 and the third liquid inlet channel 131 can supply liquid to the first flow channel 41 individually or simultaneously. The liquid in the first flow channel 41 flows through the top opening of the working chamber 24 at an accelerated speed to the spray nozzle 21, thereby forming the first functional water. The liquid in the second flow channel 14 flows through the side opening of the working chamber 24 to the working chamber 24, rotates within the working chamber 24, and is then sprayed out through the spray nozzle 21, thereby forming the second functional water.

[0045] The inlet liquid can be water, electrolyzed water, silver ion water, deodorizers, fragrances, descaling agents, or similar media. Different liquids are sprayed into the toilet bowl through different inlet channels to achieve different functions such as sterilization of the ceramic bowl surface and odor isolation through a water seal foam shield.

[0046] The spray device of the present invention integrates multiple liquid inlet channels and a spray nozzle 21, which can simultaneously achieve functions such as sterilization of ceramic pool surface and odor isolation by water seal foam shield. In addition, the spray device has a simple structure and small size, which can effectively reduce the space occupied by the toilet.
