Description

Urine splash prevention device

The present invention relates to a urinal, and more particularly to a urine splash prevention device.

Urinals allow men to urinate while standing. Traditional urinals use specific curved surfaces to guide urine and reduce splashing, but this is ineffective and increases manufacturing complexity. Consequently, some companies have developed anti-splash devices, such as anti-splash pads and three-dimensional structures composed of irregular filaments. These anti-splash devices not only reduce urine splashing but also act as a target, allowing users to control the direction of urine spray toward the anti-splash device.

However, the aforementioned anti-splash devices gradually accumulate urine scale, odor, and bacteria over time, especially in the case of three-dimensional structures composed of irregular filaments. As a result, they have a short lifespan and must be replaced frequently, resulting in high costs.

Therefore, it is necessary to provide a novel and advanced urine anti-splashing device to solve the above-mentioned problems.

The main purpose of the present invention is to provide a urine anti-splash device that can effectively prevent urine splashing, is quick to manufacture and assemble, is easy to clean, and has a long service life.

To achieve the above-mentioned objectives, the present invention provides a urine splash-preventing device comprising a base and a cover. The cover comprises at least one splash-preventing mesh and an assembly portion, the assembly portion connecting the at least one splash-preventing mesh to the base, thereby forming an internal space with the at least one splash-preventing mesh and the base. The assembly portion comprises an inner support member and an outer clamping member, respectively located on the inner and outer sides of the at least one splash-preventing mesh, to clamp the at least one splash-preventing mesh together.

The following examples are merely illustrative of possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. The words "one" or "at least one" preceding the terms mentioned herein do not limit the quantity, and the number may be "plural" as needed. Such variations in quantity also fall within the scope of protection, and are therefore described above.

Please refer to Figures 1 to 4, which show an embodiment of the present invention. The urine splash prevention device of the present invention includes: a base 1 and a cover 2.

The lid 2 includes at least one anti-splash mesh 21 and an assembly portion 3. The assembly portion 3 connects the at least one anti-splash mesh 21 to the base 1, thereby forming an internal space 4. The at least one anti-splash mesh 21 and the base 1 together enclose an internal space 4 for accommodating a deodorizing material 6, effectively reducing odor and improving toilet comfort. The assembly portion 3 includes an inner support member 31 and an outer clamping member 32, respectively located on the inner and outer sides of the at least one anti-splash mesh 21. The inner support member 31 and the outer clamping member 32 together clamp the at least one anti-splash mesh 21, thereby stably combining them into a single component.

The outer clamp 32 includes a main body 33 and at least one first coupling portion 34. The at least one first coupling portion 34 is provided on the main body 33. The main body 33 and the inner support member 31 clamp the at least one anti-splash mesh 21. The base 1 further includes at least one second coupling portion 11. When the cover 2 is covered on the base 1 along an assembly direction 52, the at least one first coupling portion 34 and the at least one second coupling portion 11 block each other in the assembly direction 52, making it convenient for the user to quickly disassemble and replace components or the deodorizing material 6, facilitating daily cleaning and maintenance, and improving convenience of use and hygiene safety.

In this embodiment, the number of the at least one first coupling portion 34 is one, and the first coupling portion 34 is arranged around the main body 33. The number of the at least one second coupling portion 11 is plural, and the plural second coupling portions 11 are arranged around the base 1 at intervals. The multi-point blocking design can enhance the coupling stability between the cover 2 and the base 1, and can effectively resist external forces and will not separate arbitrarily.

Preferably, the inner support member 31 is annular and the outer clamping member 32 is annular, which can provide more contact areas at different angles, helping the inner support member 31 and the outer clamping member 32 to be tightly matched and tightly clamped to the at least one anti-splash mesh 21.

The base 1 further includes an inner ring wall 12 and an outer ring wall 13. The outer ring wall 13 is located outside the inner ring wall 12. The inner ring wall 12 and the outer ring wall 13 together define an assembly slot 14. When the cover 2 is placed on the base 1, the assembly portion 3 is inserted into the assembly slot 14. The inner support member 31 abuts the inner ring wall 12, and the outer clip member 32 abuts the outer ring wall 13. The inner ring wall 12 and the outer ring wall 13 provide assembly alignment and further provide a stable engagement effect, which can effectively prevent the cover 2 from shaking or loosening.

In this embodiment, the number of the at least one anti-splash mesh 21 is plural, and the plurality of anti-splash meshes 21 are stacked along a stacking direction 51. The thickness of each anti-splash mesh 21 is equal to control the weight and size. Each anti-splash mesh 21 is plastic injection molded in one piece, and has the characteristics of light weight, high strength and low cost, and is convenient for mass production.

Each of the anti-splash meshes 21 is a thermochromic mesh that provides instant visual feedback, allowing the user to psychologically create a targeting effect and unconsciously control urine flow toward the multiple anti-splash meshes 21, thereby enhancing the effectiveness of preventing splashing.

More specifically, each anti-splash mesh 21 includes a main mesh structure 22, which includes a plurality of irregular holes 23. The main mesh structures 22 of the plurality of anti-splash meshes 21 are arranged in a non-overlapping manner in the stacking direction 51. This allows holes of varying sizes and shapes to be formed in the stacking direction 51, providing a greater contact area to guide urine flow and effectively diffuse the impact of urine, thereby preventing urine from splashing.

More specifically, the main mesh structures 22 of the two adjacent anti-splash meshes 21 are spaced apart to define a buffer space 26, forming an effective liquid buffer zone that absorbs the kinetic energy of urine flow and further reduces the possibility of splashing.

Each anti-splash mesh 21 further includes a secondary mesh structure 24, which is different from the primary mesh structure 22 and is disposed outside the primary mesh structure 22. The secondary mesh structure 24 includes a plurality of identically shaped elongated holes 25, which are arranged in a continuous pattern surrounding the primary mesh structure 22. These elongated holes 25 provide additional diversion and enhanced anti-splash effects, combining aesthetics with practicality.
