Description

Technical Field

[0001] This utility model relates to the technical field of urinal accessories, and more specifically, to a urine droplet receiving and flushing device for urinals. Background Technology

[0002] As civilization develops and levels of development rise, society has increasingly higher requirements for the hygiene standards of public restrooms, such as the cleanliness of the floors, urinals, and squat toilets, as well as the odor control. Urinals are commonly used by men in public restrooms. When men urinate, some urine drips onto the floor, leaving urine residue under the urinal, affecting hygiene and eventually forming urine stains that are extremely difficult to clean. Furthermore, as the urine evaporates and diffuses, it also causes unpleasant odors in the restroom.

[0003] In existing technologies, such as the "urinal anti-drip cleaning device" disclosed in CN215406394U, a urine collection tray, flushing hole, and odor-proof floor drain are installed under the toilet to collect splashed or dripping urine and flush it out, thus solving the hygiene and odor problems caused by urine residue on the floor to some extent. However, such devices still have the following drawbacks:

[0004] 1. Secondary splashing of urine: When urine drips onto the urine collection tray, the smooth surface or the impact of the rinsing water may cause the urine droplets to bounce or splash inside the tray, contaminating the shoe surface and surrounding area. 2. Inadequate user experience: Some urine collection trays are made of hard materials (such as ceramic and stainless steel) and lack flexible cushioning design. The impact sound when urine drips is obvious, and the hard surface is prone to scaling, increasing the difficulty of maintenance and cleaning. 3. Installation complexity and scenario limitations: The urine collection tray needs to be pre-embedded in the ground or installed in a groove so that its surface is flush with the ground. Construction requires damage to the existing ground structure, resulting in high renovation costs and long cycles. It is also difficult to adapt to the rapid upgrade needs of urinals already in use, and can only be flushed and maintained daily, and cannot be removed for deep cleaning.

[0005] To address the aforementioned issues, there is an urgent need for a leak-proof device that can quickly retrofit existing urinals, suppress urine splashing, and eliminate the need for complex construction, in order to adapt to diverse scenarios and reduce maintenance costs. Utility Model Content

[0006] The present invention aims to overcome at least one of the defects of the prior art and provides a urine droplet receiving and flushing device for urinals, which solves the technical problem that when urine drips onto the urine collection tray, the smooth surface of the tray or the impact of the flushing water may cause the urine droplets to bounce or splash inside the tray, thus contaminating the shoe surface and surrounding area.

[0007] The technical solution adopted by this utility model is a urine drop receiving and flushing device for a urinal, comprising: a urine drop receiving tray, disposed directly below the front side of the urinal for receiving urine droplets; a urine droplet dispersing structure disposed in the urine droplet receiving area of ​​the urine droplet receiving tray, the surface of which is constructed to physically break up urine droplets to suppress splashing; a flushing pipe connected to the urine droplet receiving tray for supplying water to the urine droplet receiving tray for flushing; and a drain pipe connected to the rear side of the urine droplet receiving tray for discharging wastewater used to flush the urine droplets. The urine droplet receiving area is the physical space in the urine droplet receiving tray that directly receives dripping urine, specifically the space inside the tray and its inner surface.

[0008] A urine droplet collection tray positioned directly below the front of the urinal collects urine droplets and utilizes a droplet-dispersing surface structure to physically break them up and suppress splashing. This effectively dissipates the impact energy of the urine droplets and prevents splashing, thus avoiding contamination of the user's shoes and surrounding area. Simultaneously, the droplet collection tray precisely collects leaked urine, which, in conjunction with the connected flushing and drain pipes, is promptly flushed away, fundamentally solving the hygiene and odor problems caused by urine residue on the floor.

[0009] Furthermore, the urine droplet dispersion structure is composed of bristles, which are evenly distributed on the inner surface of the urine droplet collection tray. The bristles are conical with their tips pointing upwards; or the urine droplet dispersion structure is a mesh, which is fixed to the top of the urine droplet collection tray, covering its port. By using a urine droplet collection tray positioned directly below the front of the urinal, and utilizing the urine droplet dispersion structure formed by the bristles on its inner surface or the mesh covering its top (the bristles disperse the kinetic energy of the urine droplets through their conical tips, while the mesh disperses the urine droplets through its surface), the impact energy of the urine droplets is effectively dissipated, and splashing is suppressed, preventing contamination of the user's shoes and surrounding area. Simultaneously, the urine droplet collection tray accurately receives leaked urine, allowing for timely flushing and drainage with the connected flushing and drain pipes, fundamentally solving the hygiene and odor problems caused by urine residue on the ground.

[0010] Furthermore, the bristles are at least 8mm long, spaced 1-5mm apart, and have a root diameter of 0.5-5mm. When the bristle design dimensions are within the aforementioned range, they provide a high splash-proof effect; when they exceed the aforementioned range, the splash area is larger. The mesh size of the grid ranges from 1mm×1mm to 5mm×5mm, the width of the edge between two grids is between 0.5-3mm, and the distance between the grid and the bottom of the urine drop collection tray is at least 8mm. When the grid design dimensions are within the aforementioned range, they provide a high splash-proof effect; when they exceed the aforementioned range, the splash area is larger, and the splash-proof effect is poor.

[0011] Furthermore, it also includes a suction cup, located on the back of the urine drop collection tray, for adsorbing and fixing the urine drop collection tray. The suction cup adsorption fixing structure adheres to the ground with silicone material, allowing for quick installation in existing urinals without modification. This ensures the stability of the device, reduces installation costs and maintenance difficulty, and facilitates easy removal for deep cleaning.

[0012] Furthermore, the flushing pipe is arranged around the edge of the urine drop collection tray, and the flushing pipe has flushing holes facing the inside of the urine drop collection tray. The flushing pipe around the edge, combined with the flushing holes that spray water inward, covers the surface of the urine drop collection tray with a ring-shaped water flow, achieving a uniform rinsing cleaning effect.

[0013] Furthermore, the urine drop collection tray and the conical bristles are made of silicone material and are integrally molded. The integral silicone molding process seamlessly connects the conical bristles to the tray body, and the flexible material surface has both anti-fouling and easy-to-clean properties as well as impact resistance and durability, ensuring that it will not deform after long-term use and is easy to clean.

[0014] Furthermore, a drain hole is provided on the rear side of the urine drop collection tray, and the drain pipe is connected to the outer end of the drain hole. The sewage discharge structure with the drain hole and drain pipe directly connected reduces liquid retention through rapid sewage discharge, and combined with the simplified pipeline design, effectively prevents odor growth and reduces the failure rate.

[0015] Furthermore, it also includes a collection tray, positioned between the drain hole and the drain pipe, to collect and guide the wastewater. The collection tray accelerates wastewater discharge through flow optimization, and its flared design prevents backflow and blockage, improving drainage efficiency and enhancing system stability.

[0016] Furthermore, the drain pipe is connected to the urinal's drainage pipe. This shared drain pipe structure with the urinal's drainage pipe achieves the dual advantages of saving space and reducing costs through space reuse and facility sharing.

[0017] Furthermore, the width of the urine drop collection tray gradually decreases from the end closest to the urinal to the end furthest from the urinal. The inverted pear-shaped urine drop collection tray adopts a narrowing design that is wider at the front and narrower at the back, combined with an ergonomic fit for the standing position. Through a flow guiding structure, it guides urine to flow naturally to the drain hole, reducing residue and improving user comfort.

[0018] A urinal flushing system includes a human body sensor, a solenoid valve, and a urine droplet receiving and flushing device for the urinal. It also includes a water distributor connected to the outlet of the solenoid valve. One output of the water distributor connects to the urinal, and the other output connects to the flushing pipe of the urine droplet collection tray via a conduit. The human body sensor detects the presence or departure of a user and triggers the solenoid valve to flush water through the water distributor into the urinal and urine droplet collection tray. The water distributor synchronously supplies water to the urinal and urine droplet collection tray, achieving simultaneous cleaning and water conservation through adjustable proportional control, significantly improving overall cleaning efficiency.

[0019] A urinal flushing system includes a urine drop receiving and flushing device for the urinals, wherein the urine drop collection tray is elongated and positioned directly below the front of multiple urinals; it also includes a timed flushing device for periodically supplying water to the flushing pipe. This multi-station system, with its elongated urine drop collection tray and timed flushing device, reduces installation complexity and maintenance requirements by covering multiple urinals and providing periodic automatic flushing, making it particularly suitable for public restrooms.

[0020] Compared with existing technologies, the beneficial effects of this invention are as follows: A urine droplet collection tray positioned directly below the front of the urinal receives urine droplets, and the droplet-dispersing surface structure physically breaks the droplets, suppressing splashing; effectively dissipating the impact energy of the urine droplets and preventing splashing that contaminates the user's shoes and surrounding area. Simultaneously, the urine droplet collection tray achieves precise collection of leaked urine, which, in conjunction with the connected flushing and drain pipes, allows for timely flushing and drainage, fundamentally solving the hygiene and odor problems caused by urine residue on the ground.

[0026] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0027] Example 1

[0028] like Figure 1 As shown, this solution discloses a urine drop receiving device for a urinal 11, including a urine drop collection tray 1, a flushing pipe 2 and a drain pipe 3 disposed on the urine drop collection tray 1.

[0029] The urine drop collection tray 1 is shaped like an inverted pear ("inverted pear" means: a symmetrical two-dimensional closed curve, with a full semi-circular arc at the top, gradually tapering symmetrically along the central axis on both sides downwards, and a semi-circular contraction at the bottom; for example, the width ratio can be set to 3:2:1.5, and the overall outline is composed of smooth and continuous arc transitions), which is convenient for people to stand on and collect urine drops. The inner surface of the urine drop collection tray 1 is evenly distributed with pointed conical bristles 4. With these bristles 4, the urine droplets will be dispersed and will not splash. Even if you step on it, the soles of your shoes will not get wet. The urine drop collection tray 1 and the bristles 4 can be molded as one piece. The urine drop collection tray 1 is made of silicone, which is non-toxic, odorless, does not easily accumulate dirt, and is easy to clean. The bristles 4 are at least 8mm long, spaced 1-5mm apart, and have a root diameter of 0.5-5mm. When the design range exceeds the aforementioned size range, the bristles 4 cannot effectively separate the urine droplets, resulting in poor splash prevention. Preferably, the bristles 4 are 9mm long, spaced 2.5mm apart, and have a root diameter of 2mm, which provides a better splash prevention effect by separating the urine droplets.

[0030] The back of the urine drop collection tray 1 is equipped with several suction cups 5 for adhering to the ground, making it easy for the urine drop collection tray 1 to be adsorbed and fixed.

[0031] The flushing pipe 2 is arranged around the edge of the urine drop collection tray 1. The flushing pipe 2 has flushing holes 6 facing the inside of the urine drop collection tray 1. The water inlet of the flushing pipe 2 is located on the rear side of the urine drop collection tray 1. The flushing pipe 2 and the urine drop collection tray 1 can be integrally formed or glued together.

[0032] The drain pipe 3 is located on the rear side of the urine drop collection tray 1. Specifically, the rear side of the urine drop collection tray 1 is provided with a drain hole 7 and an integrally formed collecting tray 8. The urine drop collection tray 1 is connected to the collecting tray 8 through the drain hole 7. The drain pipe 3 is connected to the rear side of the collecting tray 8. The collecting tray 8 is funnel-shaped and is used to collect the water discharged from the drain hole 7 and then discharge it through the drain pipe 3. As another improvement to this solution, the collecting tray 8 can be omitted, and the drain pipe 3 can be directly connected to the drain hole 7 on the rear side of the urine drop collection tray 1.

[0033] The existing urinal flushing system includes the following main components: a human body sensor 9, a solenoid valve 10, and a urinal 11. The inlet of the solenoid valve 10 is connected to tap water via a pipe, and the outlet of the solenoid valve 10 is connected to the urinal 11 via a pipe. The human body sensor 9 triggers the solenoid valve 10 to flush. The human body sensor 9 can be an infrared sensor, an ultrasonic sensor, or a capacitive proximity sensor, etc.

[0034] This device can be modified from an existing urinal 11. Specifically, the urine drop collection tray 1 is attached to the front of the urinal 11 by suction cup 5 on the back, to collect residual urine droplets after urination. A two-way water distributor 12 (which can be a T-junction) is connected to the pipeline between the solenoid valve 10 and the urinal 11. One output of the water distributor 12 is still connected to the urinal 11, and the other is connected to the inlet of the flush pipe 2 on the back of the urine drop collection tray 1 through a conduit 13. The conduit 13 can be hidden in the wall behind the urinal 11 or fixed along one side of the urinal 11. The drain pipe 3 of the urine drop collection tray 1 is connected to the drain pipe of the urinal 11 through a pipeline. Cartoon foot pedal patterns can be set on both sides of the urine drop collection tray 1. When a person steps on the pattern, the urine drop collection tray 1 can accurately collect urine droplets.

[0035] Instructions for use: The human body sensor 9 detects the user entering the usage area and triggers the solenoid valve 10 to release water for 2 seconds. Part of the water flows through the diverter 12 into the ceramic urinal 11 to wet the ceramic surface, while the other part flows through the conduit 13 into the urine drop collection tray 1 to wet the inside of the tray. During use, the urine drop collection tray 1 can collect residual urine droplets. After the user leaves, the human body sensor 9 performs a second detection and confirms, triggering the solenoid valve 10 to flush for 4-6 seconds (adjustable). Most of the water flows into the urinal 11 through the diverter 12, while a small portion flows through the conduit 13 into the urine drop collection tray 1, rinsing the urine droplets in the tray and draining them through the drain pipe 3.

[0036] As an improvement to this solution, if the urinal 11 uses a delayed self-closing valve for flushing, a water distributor 12 is installed at the lower end of the delayed valve, and the flushing function of the urine drip collection tray 1 remains unchanged. If several urinals 11 are arranged in a row, the urine drip collection tray 1 can be made into a long strip, with a timed flusher added to one end and the other end connected to the drain pipe.

[0037] The first flush primarily forms a water film within the urinal 11 and the urine dropper tray 1, effectively preventing urine from directly contacting the ceramic surface and the inner surface of the urine dropper tray 1, thus preventing sedimentation and improving the quality of cleaning. The device allows for flushing after each use, with unlimited cycles. This solves the problem of urine droplets on the floor being difficult to clean, affecting indoor air quality and floor hygiene.

[0038] Example 2

[0039] like Figure 4 As shown, this embodiment differs from Embodiment 1 in that, in this embodiment, the bristles 4 are not provided. Instead, a grid 14 is fixed on the top of the urine drop collection tray 1, covering the port of the urine drop collection tray 1. The mesh size of the grid 14 ranges from 1mm×1mm to 5mm×5mm, the width of the edge between two grids 14 is between 0.5-3mm, and the distance between the grid 14 and the bottom of the urine drop collection tray 1 is not less than 8mm. When the design range exceeds the aforementioned dimensions, the grid 14 cannot effectively separate the urine droplets, and the urine droplets will splash when they touch the surface of the grid 14. Preferably, the mesh size of the grid 14 is 2.5mm×2.5mm, the width of the edge between two grids 14 is 1mm, and the distance between the grid 14 and the bottom of the urine drop collection tray 1 is 9mm. At this time, it has a better effect of separating urine droplets and preventing splashing. The material of the grid 14 can be stainless steel, plastic, etc., and the fixing method of the grid 14 can be snap-fit, welding, or bonding. The shape of the grid 14 is rectangular.
