Description

Technical Field

[0001] This invention relates to the field of hygiene protection technology, specifically to a protective device for reducing the splashing and diffusion of droplets, bacteria and aerosols during toilet flushing. Background Technology

[0002] When a toilet is flushed, a large amount of droplets, bacteria, and aerosols are released outwards, posing a hygiene and safety hazard. Current technologies often involve flushing with the toilet lid closed, but this is insufficient to completely prevent bacteria and droplets from splashing, allowing them to splatter internally and increasing contamination of the toilet seat and lid. Some designs address splash prevention during toilet use, but these do not solve the problem of splashing during flushing. More complex splash-proof devices, while offering some protection, are costly, difficult to install, and their structures are often limited by the toilet's material and shape, lacking versatility. Furthermore, existing devices are functionally limited and cannot address additional needs such as air purification, deodorization, and antibacterial properties, making them unsuitable for daily use, especially in settings like homes, hospitals, schools, public restrooms, and nursing homes, where the droplets, bacteria, and aerosols generated during flushing can easily cause cross-infection, exacerbating hygiene and safety risks. Therefore, there is an urgent need to develop a multi-functional toilet splash-proof device that is simple in structure, highly versatile, offers various fixing methods, is easy to install and disassemble, and combines antibacterial, deodorizing, and anti-backflow odor functions. Summary of the Invention

[0003] The purpose of this invention is to provide a protective device that reduces the splashing and diffusion of droplets, bacteria and aerosols during toilet flushing, in order to solve the problems of complex structure, inconvenient installation, poor versatility and single function in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A protective device for reducing the spread of droplets, bacteria, and aerosols during toilet flushing includes a barrier layer and a fixing part. The fixing part is disposed along the edge of the barrier layer and is used to detachably fix the barrier layer to the toilet, so that the barrier layer completely covers the toilet opening and forms a physical barrier layer during flushing, preventing the spread of droplets, bacteria, and aerosols generated during flushing.

[0006] Preferably, the barrier layer and the fixing part can be fixedly connected or detachably connected to adapt to different usage requirements and ease of replacement.

[0007] Preferably, the barrier layer and / or fixing part can be a foldable structure that can switch between a folded state and an unfolded state, making it easy to carry and store.

[0008] Preferably, the barrier layer is made of a filter material, including non-woven fabric, meltblown fabric, fiber membrane, porous filter membrane, breathable paper, and breathable composite material, to achieve effective physical blocking of droplets, bacteria, and aerosols.

[0009] Preferably, the barrier layer may also be loaded with functional components, including antibacterial agents, deodorizers, and air fresheners. The antibacterial agent may be nano-silver or chitosan; the deodorizer may be activated carbon; and the air freshener may be plant fragrances. This allows the protective device to not only prevent splashing but also provide multiple functions such as air freshening, deodorizing, and antibacterial properties.

[0010] Preferably, the protective device can be installed below the toilet seat, on the upper edge of the toilet seat, or on the inside of the toilet lid to adapt to different toilet structures and usage habits.

[0011] Preferably, the barrier layer is a disposable or replaceable structure to meet different hygiene and environmental protection requirements.

[0012] Preferably, the fixing part includes an adhesive layer, an electrostatic adsorption layer, and a magnetic component. As another preferred option, the fixing part includes Velcro, a suction cup, an anti-slip mat, snap fasteners, or a counterweight structure. These fixing methods can meet the needs of toilets of different materials and in different usage scenarios, without requiring any modification to the toilet.

[0013] Preferably, the fixing part is detachably connected to the mating part provided on the toilet, which further enhances the stability and convenience of fixing.

[0014] Preferably, the fixing part is reusable and the barrier layer is a replaceable structure. After use, the barrier layer can be separated from the fixing part and replaced with a new one, thus achieving a balance between environmental protection and economy. Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Simple structure: It consists of only a barrier layer and an edge fixing part, which is easy to manufacture and has low cost.

[0016] 2. Easy installation: No tools or toilet modifications required; simply stick and use, place and remove.

[0017] 3. Multiple fixing methods: You can choose from various methods such as adhesive, electrostatic adsorption, magnetic attraction, Velcro, suction cup, anti-slip mat, snap fastener or self-weight counterweight, to adapt to different toilet materials and usage scenarios.

[0018] 4. Reliable protection: When flushing, the barrier layer covers the toilet opening, forming a physical barrier layer that effectively prevents droplets, bacteria and aerosols from spreading outward.

[0019] 5. Multifunctional: The barrier layer can be made of filter material and loaded with functional ingredients, which can not only provide protection but also freshen the air, deodorize, and inhibit bacteria.

[0020] 6. High versatility: It can be adapted to various toilet opening shapes, without being limited by model or size, and is suitable for a wide range of places such as homes, hotels, and public restrooms.

[0021] 7. Flexible use: It can be used once, or the fixed part can be reused and the barrier layer can be replaced.

[0022] 8. Convenient storage: The barrier layer and fixing part can be folded, which can be easily stored and carried without affecting the daily use of the toilet.

[0023] 9. Anti-backflow odor function: After flushing, the protective device can remain in place, continuously covering the toilet opening to prevent odors from rising and improve the air quality in the bathroom. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto. Example 1 (Direct Placement Type Protective Device)

[0032] like Figure 1 , Figure 2As shown, this embodiment provides a direct-placement protective device, including a barrier layer (1) and a fixing part (2). The barrier layer (1) is made of filter material and its shape is adapted to the toilet opening. The fixing part (2) can take various forms: In the first form, the fixing part (2) is an annular adhesive layer provided at the edge of the barrier layer (1), and the adhesive layer is covered with release paper. In use, the release paper is peeled off, and the barrier layer (1) is pasted to the opening edge of the toilet seat (6) through the adhesive layer.

[0033] As a second type, the fixing part (2) is an electrostatic adsorption layer, which uses static electricity to adsorb the barrier layer (1) onto the surface of the toilet seat (6), without the need for adhesive and can be reused.

[0034] As a third type, the fixing part (2) is made of shape memory metal and is equipped with an anti-slip pad. The shape memory metal can be a nickel-titanium shape memory alloy. When in use, the fixing part (2) automatically unfolds and forms using the elasticity of the shape memory metal, which expands the barrier layer (1) and covers the toilet opening. The anti-slip pad contacts the surface of the toilet seat (6) to increase friction and prevent displacement.

[0035] All of the above-mentioned protective devices can be folded and stored in a small bag. They can be taken out and unfolded when needed, making them easy to carry and store. The barrier layer (1) can be loaded with functional ingredients, such as nano-silver antibacterial agents and plant fragrance fresheners. After flushing, it can be removed directly or left in place until the next time the toilet is used. Depending on the situation, you can choose to continue using it or discard it directly. During this period, the protective device still covers the toilet opening and can also prevent the toilet from backflowing odors. Example 2 (Matching component type protective device - upper edge of toilet seat)

[0036] like Figure 3 As shown, this embodiment provides a protective device that needs to be used in conjunction with a fitting part (3) on a toilet, including a barrier layer (1), a fixing part (2), and a fitting part (3). The barrier layer (1) is made of filter material and its shape is adapted to the toilet opening. The fixing part (2) can take the following forms: In the first form, the fixing part (2) is a magnetically pleasing metal wire located at the edge of the barrier layer (1), and a magnetic attractor (as a mating part 3) is pre-installed at the corresponding position on the upper edge of the toilet seat (6). In use, the barrier layer (1) is fixed by magnetic attraction between the magnetically pleasing metal wire and the magnetic attractor (3).

[0037] In the second form, the fixing part (2) is a hook and loop fastener on the edge of the barrier layer (1), and a hook and loop fastener is pre-set at the corresponding position on the upper edge of the toilet seat (6) (as a fitting part 3). In use, the barrier layer (1) is fixed by the hook and loop fastener.

[0038] As a third type, the fixing part (2) is a male and female snap fastener located on the edge of the barrier layer (1), and a female snap fastener (as a mating part 3) is pre-set at the corresponding position on the upper edge of the toilet seat. In use, the barrier layer (1) is pressed and fixed by the male and female snap fasteners.

[0039] All of the above-mentioned protective devices can be made of shape memory metal materials (such as nickel-titanium shape memory alloy) for the fixing part (2) or the edge of the barrier layer (1), so that the device can be folded and stored and automatically unfolded when in use, and connected and fixed with the mating part (3).

[0040] After flushing, the barrier layer (1) and the fixing part (2) can be removed together. The mating part (3) can be fixed or detachably installed on the toilet seat (6) and can be reused. The barrier layer (1) and the fixing part (2) can be a thermoformed integral structure.

[0041] The barrier layer (1) can be loaded with functional ingredients, such as nano-silver antibacterial agents and plant fragrance fresheners. Example 3 (Matching Part Type Protective Device - Below Toilet Seat)

[0042] like Figure 4 As shown, this embodiment is similar in structure to embodiment 2, except that the mating part (3) is fixedly positioned below the toilet seat (4). It includes a barrier layer (1) and a fixing part (2). The barrier layer (1) is made of filter material, and the fixing part (2) is a magnetic metal wire, Velcro hook, or male and female snap fastener located on the edge of the barrier layer (1). A mating part (3) adapted to the fixing part (2) is preset at the corresponding position below the toilet seat (4).

[0043] In use, the barrier layer (1) is connected to the mating part (3) via the fixing part (2), and then the toilet seat (4) is lowered so that the barrier layer (1) covers the toilet opening. After flushing, the barrier layer can be removed. This position setting allows the barrier layer (1) to be pressed down after the toilet seat (4) is lowered, further enhancing the stability of the fixation. Example 4 (Plate-frame type protective device)

[0044] like Figure 5As shown, this embodiment provides a plate-type frame-type protective device, including a barrier layer (1) and a fixing part (2). The fixing part (2) is a reusable frame, which can be made of plastic (such as PP, ABS, PE), metal (such as stainless steel, aluminum alloy) or composite material. The frame is a sheet structure, and its size is larger than or equal to the toilet opening. The overall shape is any shape that can cover the toilet opening, such as square, rectangle, or circle. The middle of the frame is provided with an installation part for accommodating the barrier layer (1), and the installation part is a through opening. As an alternative, the installation part can also be an inwardly recessed groove. The shape of the installation part can be designed as circular, elliptical, rectangular or other irregular shapes. The barrier layer (1) is set in the installation part area, and its size is adapted to the installation part. The edge is connected to the edge of the installation part by a detachable connection. The peripheral part of the frame extends beyond the toilet opening range for support and removal.

[0045] The barrier layer (1) can be used once or multiple times.

[0046] When in use, place the frame at the toilet opening so that the barrier layer (1) covers the opening; after flushing, the barrier layer (1) can be removed and replaced, and the frame can be reused. Example 5 (Inner Adhesive Protective Device for Bun-Shaped Toilet Seat)

[0047] like Figure 6 As shown, this embodiment provides a protective device installed inside a toilet seat (5), including a barrier layer (1) and a fixing part (2). The barrier layer (1) is made of a flexible "bun-shaped" filter material, the shape of which is adapted to the opening of the toilet seat (4). The fixing part (2) is an adhesive layer located at the bottom of the barrier layer (1), used to attach the barrier layer (1) to the inside of the toilet seat (5). When the toilet seat (5) is lowered, the barrier layer (1) is pressed tightly against the opening of the toilet seat (4), forming a sealed cover, effectively preventing the spread of droplets, bacteria and aerosols generated during flushing. After flushing, the toilet seat (5) is lifted, and the barrier layer (1) is lifted with the toilet seat (5) without any additional operation. The barrier layer (1) can be loaded with air freshener, and the barrier layer (1) is a replaceable structure that can be torn off and replaced after a period of use.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the invention.
