Description

Technical Field

[0001] This invention belongs to the field of hygiene and cleaning equipment technology, specifically relating to a urine collection, adsorption and deodorization device for the area around urinals in restrooms. It is particularly suitable for public restrooms, office building restrooms, and home restrooms, solving the problem of ground pollution and odor caused by urine dripping during urinal use. Background Technology

[0002] In the use of existing toilet facilities, the use of urinals (especially men's urinals) is often accompanied by urine dripping onto the floor around the urinal. This problem mainly stems from splashing or dripping urine during excretion, or from incomplete cleaning after use. Dripping urine not only pollutes the floor, affecting the cleanliness and aesthetics of the toilet and creating an unsanitary situation, but also provides a nutrient source for microorganisms (bacteria, fungi, etc.) to multiply due to the organic matter (such as urea, protein, amino acids, etc.) contained in urine.

[0003] Existing technologies have significant shortcomings in addressing the aforementioned problems: Manual cleaning relies on regular wiping or rinsing, but if the cleaning frequency is insufficient, urine residue will still be decomposed by microorganisms, producing malodorous substances such as ammonia, hydrogen sulfide, and indole, resulting in a serious odor in the bathroom. In some places, ordinary absorbent mats or anti-slip mats are used, which can only achieve the basic function of absorbing urine. However, their structural design is not optimized for the "dispersed dripping" characteristics around the urinal, which can easily lead to local saturation and leakage. In addition, they do not integrate deodorization function, and the absorbed urine will still be decomposed by microorganisms in the mat, continuously producing odor. Some specialized urine collection devices only have a collection tank structure and lack efficient water absorption and deodorization components, requiring frequent emptying and cleaning, which is cumbersome to operate and can easily cause secondary pollution.

[0004] Therefore, there is an urgent need for a device that can efficiently collect dripping urine, quickly lock in water to prevent leakage, and simultaneously inhibit the growth of microorganisms and eliminate odors, in order to overcome the shortcomings of existing technologies. Summary of the Invention

[0005] (a) Technical problems to be solved This invention aims to solve the problems of ground pollution, severe odor, and high cleaning and maintenance costs caused by urine dripping around urinals. It provides a urine-absorbing and deodorizing device with a reasonable structure, convenient use, and the ability to simultaneously collect urine, efficiently absorb and retain water, and provide long-lasting deodorization.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides a urine-absorbing and deodorizing device for collecting dripping urine around a urinal. The device includes a tray and a disposable urine-absorbing and deodorizing product, and its specific structure is as follows: 1. Pallet The tray is a shallow, dish-shaped structure that conforms to the contour of the urinal bottom. Its length extends to the area in front of the urinal where the user stands (covering the common dripping area). The edge of the tray has an overflow rim with a height of 1-3cm to prevent urine or disposable products from leaking out. The tray is made of corrosion-resistant plastic (such as PP, PE) or stainless steel. The bottom may have anti-slip protrusions, or it may be detachably connected to the bottom of the urinal via Velcro or buckles, or it may be placed directly on the ground.

[0007] 2. Disposable urine-absorbing and deodorizing products The product is laid inside the pallet, adapted to the pallet size, and has a multi-layered composite structure, comprising, from top to bottom: Surface layer: Made of hydrophilic nonwoven fabric (selected from spunbond nonwoven fabric or hot air nonwoven fabric, with 10%-30% natural cotton fiber added to improve skin-friendliness), the surface has drainage channels (0.3-0.5cm wide, 1-2cm apart) that converge towards the center area, which are used to quickly receive and conduct urine to the lower layer, reducing the retention time of urine on the surface.

[0008] The drainage layer is made of composite fibers with a three-dimensional fluffy structure (such as a mixture of polyester fiber and viscose fiber). The fiber density gradually increases from the top layer to the bottom layer (top layer density 100-150g / m², bottom layer density 200-250g / m²). This can evenly disperse the urine conducted on the surface layer to the water-absorbing and deodorizing layer, avoiding leakage caused by local accumulation.

[0009] Water-absorbing and deodorizing layer: This is the core functional layer, composed of a superabsorbent polymer (SAP) and a composite deodorizer. Fluff pulp (in a weight ratio of 1-3:5-10 to SAP) may be added to enhance structural stability. The SAP is a sodium polyacrylate superabsorbent resin with a water absorption rate ≥300g / g. The composite deodorizer consists of antibacterial components, urease inhibitors, and adsorbents in a weight ratio of (1-3):(0.5-2):(5-10), specifically including: Antibacterial ingredients: selected from quaternary ammonium compounds (such as benzalkonium chloride), plant extracts (such as tea tree oil, honeysuckle extract) or their combinations, used to inhibit microbial growth and enzyme activity; Urease inhibitors: selected from acetyloxyoxime acid (AHA), used to prevent urea from being broken down into ammonia; Adsorbent: Selected from activated carbon, zeolite or diatomaceous earth or a mixture thereof, used for the physical adsorption of malodorous molecules.

[0010] Leak-proof layer: It uses a breathable PE membrane (thickness 0.01-0.03mm) or a breathable bottom membrane formed by PE membrane and breathable non-woven fabric. Its edge is provided with a positioning edge that matches the anti-overflow edge of the tray, which can prevent urine in the water-absorbing and deodorizing layer from leaking out of the tray, while allowing gas to escape to avoid stuffiness. Beneficial effects

[0011] Compared with the prior art, the present invention has the following beneficial effects: Efficient collection and leak prevention: The tray design fits the area around the urinal, fully covering the area where urine drips; the multi-layer structure of the disposable product (dispersing layer + impermeable layer) effectively prevents urine leakage and solves the problem of ground pollution; Long-lasting deodorization: Through the triple action of "antibacterial inhibition + enzyme activity blocking + malodor adsorption" of the compound deodorant, it prevents the decomposition of organic matter in urine from the source and eliminates the odor that has been generated. Tests have shown that the ammonia release after urine absorption is ≤0.1mg / m³ within 24 hours. Easy to use: Disposable products can be replaced periodically (every 1-3 days depending on usage frequency), requiring no cleaning and reducing maintenance costs; Highly adaptable: By adjusting the ratio of compound deodorants and the selection of materials, it can adapt to the needs of different scenarios such as public restrooms (high frequency of use) and family bathrooms (emphasizing skin-friendliness).

Detailed Implementation The present invention will be further described below with reference to specific embodiments, but these embodiments do not constitute a limitation on the scope of protection of the present invention.

[0013] Example 1 (for public restrooms) Tray: Made of PP material, 50cm long, 30cm wide, with a 2cm spill rim and anti-slip protrusions on the bottom, placed directly on the ground in front of the urinal; Disposable urine absorbent and deodorizing product: Size compatible with tray (48cm×28cm), parameters for each layer are as follows: Surface layer: spunbond nonwoven fabric (30g / m²), with 0.4cm wide guide grooves on the surface, spaced 1.5cm apart, radiating towards the center; The flow guide layer is a three-dimensional fluffy structure made of a blend of polyester and viscose fibers (upper layer density 120g / m², lower layer density 220g / m²). Water-absorbing and deodorizing layer: SAP (70 parts by weight) and fluff pulp (30 parts by weight) are mixed, and a composite deodorizing agent (accounting for 8% of the total weight of the water-absorbing and deodorizing layer) is added, including benzalkonium chloride (2 parts by weight), acetyloxyoxime acid (1 part by weight), and activated carbon (8 parts by weight). Impermeable layer: breathable PE membrane (0.02mm thick), with a 5mm wide positioning edge.

[0014] When in use, urine drips onto the surface and quickly enters the diversion layer through the diversion channel. The diversion layer evenly disperses the urine into the water-absorbing and deodorizing layer, where SAP quickly absorbs the water to form a gel that locks in moisture. In the compound deodorizer, benzalkonium chloride inhibits the growth of microorganisms such as E. coli, acetyloxyoxime acid blocks the decomposition of urea, and activated carbon adsorbs trace amounts of malodor molecules, achieving no obvious odor for 72 hours.

[0015] Example 2 (for home bathroom) Tray: Made of stainless steel, 40cm long and 25cm wide, it fits the bottom of the toilet bowl with a curve, and the overflow rim is 1.5cm high. It is connected to the bottom of the urinal with Velcro. Disposable urine absorbent and deodorizing product: Size 40cm × 25cm, parameters of each layer are as follows: Surface layer: Hot air nonwoven fabric (containing 20% ​​natural cotton fiber, weight 35g / m²), with 0.3cm wide guide grooves on the surface; - Flow-guiding layer: composite fiber (upper layer density 100g / m², lower layer density 200g / m²); - Water-absorbing and deodorizing layer: SAP (80 parts by weight), with added composite deodorant (6% of total weight), including tea tree oil extract (1 part by weight), acetyloxyxamic acid (0.5 parts by weight), and zeolite (5 parts by weight). Leak-proof layer: PE membrane composite breathable non-woven fabric. This embodiment uses natural antibacterial ingredients to enhance skin-friendliness, making it suitable for home use. It can achieve no odor within 48 hours, and the surface has a softer touch.
