Urinal Anti-splash device

Abstract

This invention relates to a urinal anti-splash device, which includes a base body and a cover body. The cover body is placed over the base body, collectively forming an internal space. The cover body comprises multiple anti-splash mesh structures stacked along an assembly direction. Each anti-splash mesh structure includes a grid structure, and all the grid structures are identical but arranged in a partially overlapping configuration along the assembly direction. This configuration creates holes of varying sizes and shapes along the assembly direction, providing increased contact surface area to interact with and guide the flow of urine. The urinal anti-splash device effectively prevents urine splashing, allows for quick manufacturing and assembly, is easy to clean, and has a longer service life.

Description

Technical Field

[0001] This invention relates to urinals, and more particularly to a urinal anti-splash device. Prior Technology

[0002] Urinals allow men to urinate while standing. Traditional urinals use specific curved angles to guide urine and reduce splashing, but this is ineffective and increases manufacturing difficulty. Therefore, manufacturers later developed anti-splash devices, such as anti-splash pads and three-dimensional structures made of irregular filaments. These anti-splash devices not only reduce urine splashing but also have a targeting function, allowing users to control the direction of urine spraying towards the anti-splash device.

[0003] However, the aforementioned anti-splash devices will gradually accumulate urine residue, odor, and bacteria as they are used over time, especially the irregular filamentous three-dimensional structure, which is the most obvious. Their lifespan is quite short, so they must be replaced frequently, resulting in high operating costs.

[0004] Therefore, it is necessary to provide a novel and progressive anti-splash device for urinals to solve the above-mentioned problems. Summary of the Invention

[0005] The main objective of this invention is to provide a urinal anti-splash device that can effectively prevent urine from splashing, and is quick to manufacture and assemble, easy to clean, and has a good service life.

[0006] To achieve the above objectives, the present invention provides a urinal anti-splash device, comprising: a base and a cover. The cover is disposed on the base, thereby jointly enclosing an internal space. The cover includes a plurality of anti-splash meshes stacked along a joint direction. The plurality of anti-splash meshes are independently layered in the joint direction, and each anti-splash mesh includes a mesh structure. The mesh structures of the plurality of anti-splash meshes are configured in a partially overlapping manner in the joint direction. Simple Explanation of the Diagram

[0008] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The use of "a" or "at least one" before the terms mentioned herein is not a limitation on the quantity, and may also be "multiple" depending on the requirements. Such variations in quantity are also within the scope of protection, and are therefore stated in advance.

[0009] Please refer to Figures 1 to 7, which show one embodiment of the present invention. The urinal anti-splash device of the present invention includes: a body 1 and a cover 2.

[0010] The cover 2 is placed on the base 1 to form an internal space 71. The internal space 71 can accommodate a deodorizer 72 to reduce the odor of urine. The cover 2 includes a plurality of splash-proof meshes 3 stacked along a connection direction 8. The plurality of splash-proof meshes 3 are independently layered in the connection direction 8. Each splash-proof mesh 3 includes a mesh structure 4. The mesh structures 4 of the plurality of splash-proof meshes 3 are not completely overlapped in the connection direction 8, thereby forming holes of different sizes and shapes in the connection direction 8, so as to have more contact area to contact and guide the flow of urine, thereby achieving the purpose of preventing urine splashing. The mesh structures 4 of each splash-proof mesh 3 are the same.

[0011] Preferably, each of the splash guards 3 is a thermochromic mesh to provide immediate visual feedback, creating a psychological target effect for the user, thereby unconsciously controlling the urine to flow towards the plurality of splash guards 3, thus enhancing the effectiveness of splash prevention.

[0012] Alternatively, each of the splash guards 3 is integrally molded from plastic via injection molding to facilitate rapid production.

[0013] Furthermore, the thickness of each splash guard 3 is equal to control the weight and size. The plurality of splash guards 3 can be further divided into a first net 31, at least one second net 32 ​​and a third net 33, which are independent components before assembly. The at least one second net 32 ​​is clamped and confined between the first net 31 and the third net 33 in the assembly direction 8. The production end can adjust the number of the at least one second net 32 ​​according to actual usage requirements.

[0014] Furthermore, the first mesh body 31 is provided with at least one first positioning part 51, and the at least one second mesh body 32 is provided with at least one second positioning part 52. The at least one second positioning part 52 can be detachably engaged with the at least one first positioning part 51 to improve the stability of the assembly. For example, but not limited to, one of the at least one first positioning part 51 and the at least one second positioning part 52 is a through hole 511 extending in the transverse assembly direction 8, and the other is a protrusion 521 extending in the transverse assembly direction 8. The interlocking of the concave and convex structures enables rapid assembly.

[0015] In this embodiment, there are multiple first positioning portions 51 arranged around the first mesh body 31, and multiple second mesh bodies 32, each of which is provided with multiple second positioning portions 52. The multiple second positioning portions 52 of the multiple second mesh bodies 32, which are overlapped in the assembly direction 8, are inserted into the same first positioning portion 51 to facilitate rapid assembly. It is worth noting that the number of multiple second positioning portions 52 provided in each second mesh body 32 is the same and they are arranged at the same angular interval. When the second positioning portions 52 of each second mesh body 32 are overlapped in the assembly direction 8, the mesh structure 4 of the multiple second mesh bodies 32 is not completely overlapped in the assembly direction 8, which has the advantage of simple assembly.

[0016] Preferably, the periphery of the first mesh 31 has an arc-shaped structure, and the second positioning part 52 of the second mesh 32, which is closer to the first mesh 31, is shorter in length in the vertical assembly direction 8, so that the assembler can visually identify the upper and lower positions of the assembly.

[0017] It should be noted that, in addition to the mesh structure 4, the third mesh 33 is also provided with a plurality of guide holes 53. The plurality of guide holes 53 connect the through holes 511 of the first mesh 31 and the internal space 71. The plurality of guide holes 53 are arranged around the outer side of the mesh structure 4 to guide the urine flowing through the plurality of through holes 511 and the plurality of protrusions 521.

[0018] The cover 2 further includes a connecting body 6, which covers the periphery of the plurality of splash guards 3. Specifically, the periphery of the first net 31 and the periphery of the third net 33 are fitted together and covered by the connecting body 6. The outer side wall of the connecting body 6 is recessed with an annular groove 61. The base 1 includes a plurality of locking protrusions 14, which are embedded in the annular groove 61 to stably clamp the cover 2.

[0019] More specifically, the base 1 further includes an inner ring protrusion 11, an outer ring protrusion 12, and a plurality of ribs 13. The inner ring protrusion 11 and the outer ring protrusion 12 are coaxially arranged. The plurality of ribs 13 are laterally connected to the inner ring protrusion 11 and the outer ring protrusion 12. The plurality of locking protrusions 14 are radially protruding on one side of the outer ring protrusion 12 facing the inner ring protrusion 11. The sleeve body 6 further includes at least one clamp 62, which clamps one of the ribs 13, thereby preventing the cover 2 from rotating relative to the base 1.
