Description

Urine splash prevention device

This work is related to urinals, specifically 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 this invention is to provide a urine anti-splash device that can effectively prevent urine splashing, is quick to manufacture and assemble, easy to clean, and has a long service life.

To achieve the above objectives, this invention provides a urine splash prevention device comprising: a base and a cover. The base has a first threaded section; the cover includes at least one splash prevention mesh and a connecting portion, the at least one splash prevention mesh being connected to the connecting portion. The connecting portion has a second threaded section that is threadedly connected to the first threaded section, thereby enclosing an internal space between the at least one splash prevention mesh and the base.

The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection for 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 should be stated in advance.

Please refer to Figures 1 to 3, 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 base 1 has a first threaded section 11. The lid 2 includes at least one anti-splash mesh 21 and an assembly portion 26. The at least one anti-splash mesh 21 is connected to the assembly portion 26. The assembly portion 26 has a second threaded section 27, which is threadedly connected to the first threaded section 11. The at least one anti-splash mesh 21 and the base 1 together define an internal space 32. The internal space 32 is used to accommodate a deodorizing material 4, effectively reducing odor and improving the comfort of the toilet environment.

In this embodiment, the first thread segment 11 is an external thread, and the second thread segment 27 is an internal thread. This mutually threaded design facilitates assembly and disassembly, and provides excellent joint stability after mutual connection. Of course, the present invention is not limited to the above assembly configuration. Another embodiment, as shown in FIG4 , can also be used, in which the first thread segment 11A is an internal thread and the second thread segment 27A is an external thread.

Please further refer to the present embodiment of Figures 1 to 3. The urine anti-splash device further includes a stopper 12, the extension direction of the stopper 12 is transverse to the first threaded section 11, and the stopper 12 is provided on one of the base 1 and the cover 2. When the cover 2 and the base 1 are screwed together to a predetermined position, the stopper 12 abuts against the other of the base 1 and the cover 2. In this embodiment, the stopper 12 is provided on the base 1. The stopper 12 can limit the depth of the screw connection between the cover 2 and the base 1 to avoid over-screwing. At the same time, the stopper 12 can provide additional support from different directions, thereby enhancing the stability of the connection.

The at least one anti-splashing mesh 21 is plural in number, and the plurality of anti-splashing meshes 21 are stacked along a stacking direction to form a multi-layer buffer structure to divert urine and disperse the impact force, thereby achieving the purpose of preventing splashing.

Preferably, the plurality of anti-splash meshes 21 are detachably screwed together. This design allows for easy removal or replacement of each anti-splash mesh 21, facilitating cleaning, maintenance, and subsequent repairs. Furthermore, the screwed connection provides excellent stability and prevents separation during use.

Each anti-splash mesh 21 includes a main mesh structure 22 containing a plurality of irregular holes 23. The main mesh structures 22 of the multiple anti-splash meshes 21 are arranged in a non-overlapping arrangement in the stacking direction. This creates holes of varying sizes and shapes along the stacking direction, providing more 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 two adjacent anti-splash meshes 21 are spaced apart to collectively define a buffer space 31, 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.

Preferably, each of the anti-splash meshes 21 is a thermochromic mesh to provide instant visual feedback, allowing the user to psychologically produce a targeting effect, thereby unconsciously controlling urine toward the multiple anti-splash meshes 21, thereby enhancing the effectiveness of preventing splashing.

Another preferred material of each of the anti-splash meshes 21 and the connecting portion 26 is plastic, which has the advantages of being lightweight, high-strength, low-cost, and easy to mass-produce.

The base 1 further includes an inner ring wall 13, an outer ring wall 14, and a plurality of connecting ribs 15. The outer ring wall 14 is located outside the inner ring wall 13 and can provide multiple levels of structural strength and support. The plurality of connecting ribs 15 are spaced apart and connected between the inner ring wall 13 and the outer ring wall 14, which helps to enhance the rigidity and durability of the entire base 1 and prevent structural deformation. The inner and outer annular walls 13 and 14 define a joint slot 16. When the cover 2 is mounted on the base 1, the joint portion 26 is inserted into the joint slot 16. The joint portion 26 and the outer annular wall 14 are threadedly connected to each other. This ensures that the cover 2 is securely mounted, preventing loosening or displacement during use, thereby improving the reliability and service life of the product as a whole.
