However, with technological advancements, modern smart toilets don't require excessive flushing pressure. Otherwise, a high water flow rate can cause splashing and sloshing, potentially posing a risk of electrical leakage to the smart toilet seat and compromising user safety. Furthermore, prolonged exposure to water can lead to corrosion and shorten the seat's lifespan. Additionally, customers are easily splashed with water while using the toilet, negatively impacting their experience. Utility Model Content

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis.

[0026] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please refer to Figures 1-4 This utility model provides a nozzle device, including a nozzle body 1 and a nut 2. The nozzle body 1 is provided with a water outlet channel 10. The water outlet 11 of the water outlet channel 10 is provided at one end of the nozzle body 1, and the water inlet 12 of the water outlet channel 10 is provided at one end of the nozzle body 1. The diameter of the water outlet 11 is larger than the diameter of the water inlet 12, and the inner diameter of the water outlet channel 10 gradually increases along the water outlet direction.

[0029] The outer wall of the nozzle body 1 is provided with a threaded area 13, the threaded area 13 is provided with threads, and the nut 2 is threadedly connected to the threaded area 13.

[0030] The outer edge of the water inlet 12 is provided with a flange 14.

[0031] In the nozzle device, the inner diameter of the water outlet channel 10 of the nozzle body 1 gradually increases along the water outlet direction, forming a funnel shape. The diameter of the water outlet 11 is larger than the diameter of the water inlet 12. According to Bernoulli's principle, under the same pressure conditions, the larger the volume of the water outlet channel 10, the lower the flow velocity. Therefore, it can effectively reduce the water outlet pressure and the impact force of the water flow, avoiding splashing and drifting when the smart toilet is in use, thereby reducing splashing and drifting problems and improving the user experience.

[0032] Moreover, the water flow from the nozzle device is gentle and does not splash, significantly reducing the chances of the smart cover being splashed with water. This improves customer safety and prevents corrosion caused by splashing water, thus extending the cover's lifespan.

[0033] The flange 14 engages with the nut 2 to clamp the nozzle assembly, securing it to the nozzle mounting position on the smart toilet. The nut 2 is threaded onto the threaded area 13; simply tighten the nut 2 to install or remove the nozzle assembly.

[0034] Specifically, it also includes a gasket 3, which is sleeved on the outer periphery of the nozzle body 1 and is located between the nut 2 and the flange 14.

[0035] The washer 3 can disperse the pressure applied by the nut 2 to the flange 14, preventing damage to the nut 2 or the flange 14 due to excessive pressure. In addition, it can increase the friction between the nut 2 and the flange 14, reduce the possibility of the nut 2 loosening, and keep the connection firm.

[0036] Specifically, at least one annular protrusion 15 is provided on the outer side of the nozzle body 1 near the water inlet 12.

[0037] With the above structure, when one end of the nozzle body 1 is connected to the external water supply pipe, the nozzle body 1 can use its annular protrusion 15 to hold the water supply pipe in place, thus preventing the nozzle body 1 from moving backward.

[0038] Specifically, the diameter of the outlet 11 is 16-20 mm.

[0039] Specifically, the diameter of the inlet 12 is 9-12 mm.

[0040] In one specific embodiment of this utility model, the diameter of the outlet 11 is 18mm, and the diameter of the inlet 12 is 10mm. Using these diameters ensures that the water jet from the nozzle has sufficient initial velocity while avoiding excessive impact force that could cause splashing.

[0041] Optionally, the length of the nozzle body 1 is 75-100 mm.

[0042] If the nozzle body 1 is too long, it may result in low efficiency and structural instability; if the nozzle body 1 is too short, the water flow range will be limited, and it may not be able to meet the expected cleaning requirements. In the above specific embodiment, the length of the nozzle body 1 is 80mm.

[0043] Optionally, the length of the threaded area 13 is 45 to 60 mm.

[0044] In the above embodiment, the length of the threaded area 13 is 50mm. An excessively long threaded area 13 would complicate installation, requiring more rotation to fully tighten, increasing installation time and difficulty. Conversely, an insufficiently long threaded area 13 reduces the contact area of ​​the connecting parts, resulting in insufficient load-bearing capacity and making the threads prone to stripping or damage.

[0045] This utility model also provides a splash-proof toilet, wherein the splash-proof toilet 4 uses one of the above-mentioned spray head devices.

[0046] The splash-proof toilet 4, using the aforementioned nozzle device, effectively reduces water pressure and impact force, preventing splashing and drifting during use, thus minimizing these issues and improving the user experience. Furthermore, the nozzle device sprays a gentle water flow, preventing splashing and significantly reducing the chance of the smart toilet seat being splashed, improving user safety and preventing corrosion from water splashes, thereby extending the seat's lifespan.

[0047] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
