Description

Technical Field

[0001] The present application relates to the technical field of bathroom equipment, and in particular to a disinfection floor drain. Background Art

[0002] The disinfection floor drain is a new type of floor drain product with a disinfection chamber. The disinfection floor drain is equipped with a disinfection chamber and related components that can be used to place disinfectants at the sealing cover of the floor drain, thereby effectively killing bacteria and viruses, preventing odors from rising and pests from entering the room.

[0003] In related technologies, a disinfection chamber is typically located above or in the middle of a floor drain. It is a relatively independent space used to store disinfectants or house disinfection equipment such as ultraviolet lamps. Some disinfection chambers have removable lids or sealed doors to facilitate regular addition or replacement of disinfectants and maintenance of disinfection equipment.

[0004] Regarding the related technologies mentioned above, a disinfectant is placed on top of a floor drain to disinfect it. Typically, pest control requires the use of strong drugs and professional personnel. If the disinfectant produces harmful gases, they can spread indoors and endanger human health. Therefore, it is necessary to provide a disinfectant floor drain that can not only place strong drugs to thoroughly disinfect pests, but also prevent harmful gases from spreading indoors. Summary of the Invention

[0005] In order to enable strong drugs to be placed in the floor drain to completely disinfect pests and prevent harmful gases from spreading into the room, the present application provides a disinfection floor drain.

[0006] The present application provides a disinfection floor drain using the following technical solution: A disinfection floor drain, comprising a floor drain housing, a sealing cover for sealing the floor drain housing, and a telescopic rod structure for connecting the sealing cover and the floor drain housing; The sealing cover is provided with a disinfection chamber for containing disinfection tablets below, and at least one water droplet is opened at the bottom of the disinfection chamber. The sealing cover is provided with a diversion slope on the bottom side, and at least one end of the diversion slope extends to the edge of the sealing cover.

[0007] By adopting this technical solution, the disinfection chamber is located below the sealing cover, rather than above the floor drain, creating a relatively enclosed space. When a strong disinfectant is applied, the sealing cover and the floor drain housing work together to block the harmful fumes emitted by the agent, confining them to the drain (or pipe) and reducing the risk of the fumes spreading indoors. The sealing cover and the drain housing are connected by a telescopic rod, which seals and opens the cover, preventing the backflow of gases in the pipe during sealing. A drain hole at the bottom of the disinfection chamber allows water to flow through, dissolving the disinfectant tablets and allowing the drug to enter the drain pipe, disinfecting pests (such as cockroaches and moths) and their eggs. The diversion slope on the bottom of the sealing cover extends to the edge. During high water flow, water flows rapidly along the edge of the sealing cover. During slow water flow, water flows along the diversion slope and enters the disinfection chamber, dissolving the disinfectant tablets and evenly distributing the dissolved drug solution into the drain pipe, enhancing its ability to eliminate pests.

[0008] Furthermore, the number of the guide slope is at least one.

[0009] By adopting the above technical solution, the number of diversion slopes can be one or more. The solution with a single diversion slope can achieve the effect of guiding the water flow from the edge of the sealing cover into the disinfection chamber, but the water diversion efficiency of a single diversion slope is limited by the width and inclination angle of the slope, and the water diversion efficiency is relatively low. If multiple diversion slopes are set, the flow rate of water entering the disinfection chamber per unit time can be increased, and the water diversion efficiency is improved. Multiple diversion slopes can simultaneously guide water flow in different directions, ensuring that sufficient water flow contacts the disinfection tablets and avoiding ineffective flushing of the agent.

[0010] Furthermore, the disinfection cabin is movably connected to the lower side of the sealing cover.

[0011] By adopting the above technical solution, the movably connected disinfection cabin can be easily opened, closed or disassembled from the lower side of the sealing cover, so that new disinfection tablets can be easily put in.

[0012] Furthermore, the disinfection cabin includes a first side panel and a second side panel arranged in a V shape and connected as a whole, and a first baffle and a second baffle arranged between the first side panel and the second side panel and used to block the disinfection plate, and the drain hole is opened on the first baffle and / or the second baffle.

[0013] By adopting this technical solution, the V-shaped structure of the first and second side panels forms a funnel-shaped cavity that is wide at the top and narrow at the bottom. As water enters the chamber, the contraction of the cross-section creates an acceleration effect, enhancing the flushing of the disinfectant tablets and improving the efficiency of the drug dissolution. The V-shaped side panels guide the water flow toward the center, ensuring even coverage of the disinfectant tablets and avoiding the localized, rapid drug consumption that can occur in traditional rectangular chambers due to biased water flow.

[0014] Furthermore, the bottom of the sealing cover is provided with a plug-in slot for installing the disinfection cabin near the edge, and the first side plate and the second side plate are both provided with a protrusion on the top side for inserting the plug-in slot.

[0015] By adopting the above technical solution, the insertion slot at the bottom of the sealing cover and the convex edge on the top side of the disinfection cabin adopt a mortise and tenon fit, and the slot width matches the convex edge thickness to ensure automatic alignment during insertion. Disassembly and assembly can be completed without tools. Compared with traditional screw fixing or overall disassembly methods, the operation steps are greatly simplified and can be completed without tools, which significantly improves maintenance efficiency and lowers the user threshold.

[0016] Furthermore, the bottom of the sealing cover is provided with a hinge seat on one side for hinged connection of the first side panel, the bottom of the sealing cover is provided with a buckle for connecting the second side panel on the side away from the hinge seat, and the second side panel is provided with a slot on the top side for the buckle to be inserted into.

[0017] By adopting the above technical solution, one side of the disinfection cabin is hinged to the sealing cover, and the other side is fixed by a buckle and a slot, forming a flip-up opening and closing structure. The dual fixing method of the hinged seat and the buckle ensures that the disinfection cabin is firmly connected to the sealing cover during normal use. The hinged setting makes the opening and closing process of the disinfection cabin smooth, avoiding the displacement of the internal agent due to shaking. The close fit between the buckle and the slot provides a reliable locking force in the closed state, preventing the disinfection cabin from accidentally opening due to water impact or vibration. During maintenance, the user only needs to press the buckle to disengage it from the slot, and then the disinfection cabin can be opened like turning a book, which is convenient for quickly placing or replacing disinfection tablets.

[0018] Furthermore, the floor drain housing includes an outer housing, an inner housing, and a connecting sleeve for sealingly connecting to a pipeline. A first sealing ring is provided between the outer housing and the inner housing, and a second sealing ring is provided between the outer housing and the connecting sleeve.

[0019] By adopting this technical solution, the first sealing ring is positioned at the joint between the outer and inner shells to achieve a static seal between the two. When the outer and inner shells are assembled, the first sealing ring is squeezed to form a radial seal, preventing sewage inside the floor drain from leaking through the gap between the shells. The second sealing ring achieves a dynamic seal between the outer shell and the connecting sleeve when the connecting sleeve is connected to the drainage pipe. The second sealing ring forms a seal through axial compression, adapting to slight pipe deviations or impact vibrations caused by water flow in high-rise drainage pipes, and preventing air or water leaks at the pipe joint.

[0020] Furthermore, the telescopic rod structure includes a mounting rod arranged along the diameter direction of the inner shell, a telescopic sleeve fixedly connected to the center position of the mounting rod, and a telescopic rod slidably installed in the connecting sleeve, and the sealing cover is fixedly connected to the lower end of the telescopic rod; A first magnetic block is embedded in the upper end of the telescopic rod, and a second magnetic block for cooperating with the first magnetic block is provided in the connecting sleeve.

[0021] By adopting this technical solution, the mounting rod is positioned along the diameter of the inner shell, providing lateral support for the telescopic rod. The nested telescopic sleeve within the telescopic rod limits the rod's radial movement, ensuring vertical movement and preventing the sealing cover from wobbling or shifting during movement, thereby ensuring a precise seal between the sealing cover and the drain housing. Even under the impact of high-flow drainage, the stable telescopic rod structure maintains the sealing cover's normal trajectory, ensuring a reliable seal. A first magnet at the upper end of the telescopic rod and a second magnet within the telescopic sleeve attract each other, forming a magnetic seal. When drainage is complete and the impact of the water flow subsides, the magnetic force drives the telescopic rod, causing the sealing cover to automatically rise and securely fit against the bottom of the drain housing, achieving a rapid seal and effectively preventing the upward flow of odors and harmful gases from the pipe. During drainage, the impact of the water flow overcomes the magnetic attraction, pushing the telescopic rod down and opening the drain channel. This automatically switches between draining and sealing, eliminating manual operation and enhancing user convenience.

[0022] Furthermore, the sealing cover is provided with a sealing guide surface at the edge of the top side for sealing with the lower edge of the inner shell, and the inner shell is provided with an inclined guide surface matching the sealing guide surface on the inner wall near the lower end.

[0023] By adopting the above technical solution, a sealing guide surface is provided on the top edge of the sealing cover, typically in the form of an outwardly inclined conical surface, to ensure sealing when in contact with the inner shell. The inclined guide surface is located at the lower end of the inner wall of the inner shell and is a corresponding inwardly inclined conical surface, forming a convex-concave fit with the sealing guide surface. When the sealing cover rises, the two inclined surfaces guide each other, automatically correcting the radial position of the sealing cover, ensuring uniform pressure on the sealing surface and avoiding localized air leakage caused by installation deviations in traditional flat seals. After drainage is completed, negative pressure may be generated in the pipeline. At this time, the cooperation between the sealing guide surface and the inclined guide surface can form a pressure-assisted seal. The external atmospheric pressure pushes the sealing cover upward, making the two inclined surfaces fit more tightly, and the sealing effect increases with the increase of the air pressure difference.

[0024] Furthermore, the first side plate and the second side plate jointly form a ridge on the bottom side for breaking fluid pressure.

[0025] By employing this technical solution, the instantaneous vacuum generated during drainage creates negative pressure in the pipe, generating an upward suction force that hinders the descent of the sealing cover. The ridges are located on the bottom of the disinfection chamber. When water flows through, their sharp edges trigger the separation of the fluid boundary layer, generating turbulent vortices. This turbulence converts the negative pressure energy in the pipe into kinetic energy of the fluid, reducing the peak negative pressure and the suction force on the sealing cover, ensuring that it descends normally under the impact of the water flow.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The disinfection floor drain forms an independent closed space by placing the disinfection cabin under the sealing cover, which blocks the harmful gases emitted by strong chemicals from spreading into the room, thus avoiding threats to human health from the source. The drain hole at the bottom of the disinfection cabin and the diversion slope on the bottom side of the sealing cover work together. When the water flow is slow, the diversion slope guides the water into the disinfection cabin to dissolve the chemicals, so that the liquid medicine flows deep into the pipe with the water to kill pests such as cockroaches and moths and their eggs; when the water flow is large, most of the water flows directly from the edge of the sealing cover to reduce excessive dissolution of the chemicals, thereby ensuring the disinfection effect and avoiding waste of chemicals. The number of diversion slopes can be flexibly set according to the usage scenario. A single slope can achieve basic water diversion function, and multiple slopes can simultaneously guide water flows in different directions, accelerate diversion during large-flow drainage, and ensure full contact between the chemicals and the water flow; 2. The V-shaped side panels, combined with double baffles, create a funnel-shaped cavity in the disinfection chamber to accelerate water scouring and prolong the contact time between water and the agent, allowing the agent to fully dissolve and evenly distribute in the pipe, thus achieving complete extermination of pests. The ridges on the bottom of the disinfection chamber can break the negative pressure in the pipe, reducing the adsorption force of the negative pressure on the sealing cover, allowing the sealing cover to descend normally under the impact of the water flow to drain, thus solving the problem of poor drainage caused by negative pressure.

[0027] 3. The disinfection cabin can adopt a flip-top connection structure with a hinged seat and a buckle, or a mortise and tenon structure with an inserted slot and a raised edge. Both installation structures can be quickly opened, closed and disassembled without tools, which is convenient for regular delivery or replacement of drugs. The modular design of each component reduces the difficulty and cost of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-7 , Example 1, Example 2 and Example 3, further describe this application in detail.

[0037] Example 1 The embodiment of the present application discloses a disinfection floor drain. Figure 1 and Figure 2 The disinfection floor drain comprises a floor drain housing 1, a sealing cover 2, and a disinfection chamber 3. The sealing cover 2 is used to seal the bottom of the floor drain housing 1, thereby isolating the gas in the pipeline and preventing the return of odorous gases. The disinfection chamber 3 is located below the sealing cover 2 and is filled with disinfection tablets 4 to eliminate pests in the pipeline.

[0038] Combine Figure 3 The floor drain housing 1 includes an outer shell 11, an inner shell 12, and a connecting sleeve 13 for sealingly connecting with the pipeline. A first sealing ring 14 is provided between the outer shell 11 and the inner shell 12. The first sealing ring 14 realizes static sealing between the outer shell 11 and the inner shell 12 at the socket joint of the outer shell 11 and the inner shell 12. When the outer shell 11 and the inner shell 12 are assembled, the first sealing ring 14 is squeezed to form a radial seal, preventing the sewage inside the floor drain from leaking from the shell gap. A second sealing ring 15 is provided between the outer shell 11 and the connecting sleeve 13. When the connecting sleeve 13 is connected to the drainage pipe, the second sealing ring 15 realizes dynamic sealing between the outer shell 11 and the connecting sleeve 13. The second sealing ring 15 forms a seal through axial extrusion, adapting to slight deviation of the pipeline or impact vibration of water flow in high-rise drainage pipelines, and preventing air or water leakage at the pipeline interface.

[0039] Near the upper end of the inner housing 12, a telescopic rod structure 16 is provided for connecting to the sealing cover 2. This structure comprises a mounting rod 161, a telescopic sleeve 162, and a telescopic rod 163. Mounting rod 161 extends along the diameter of the inner housing 12 and is integrally connected to the inner housing 12. Telescopic sleeve 162 is fixedly connected to the center of the lower side of mounting rod 161. Telescopic rod 163 is slidably mounted within the connecting sleeve 13. The sealing cover 2 is fixedly connected to the lower end of telescopic rod 163.

[0040] A first magnet 164 is embedded in the upper end of the telescopic rod 163, and a second magnet 165 is provided within the telescopic sleeve 162 for cooperating with the first magnet 164. The first magnet 164 and the second magnet 165 attract each other to form a magnetic sealing mechanism. When drainage is completed and the impact of the water flow weakens, the magnetic force drives the telescopic rod 163 to automatically raise the sealing cover 2, tightly fitting with the bottom of the floor drain housing 1, achieving a rapid seal and effectively blocking the upward flow of odor and harmful gases in the pipe. During drainage, the impact of the water flow can overcome the magnetic attraction, pushing the telescopic rod 163 down and opening the drainage channel. The automatic switching between drainage and sealing can be completed without manual operation, improving user convenience.

[0041] Combine Figure 4 The sealing cover 2 is provided with a sealing guide surface 21 at the edge of the top side for sealing with the lower edge of the inner shell 12. The inner shell 12 is provided with an inclined guide surface 121 matching the sealing guide surface 21 on the inner wall near the lower end.

[0042] Reference Figure 5 The sealing cover 2 is provided with a guide slope 22 on its bottom side. Both ends of the guide slope 22 extend to the edges of the sealing cover 2. The disinfection chamber 3 is movably connected to the bottom side of the sealing cover 2. When the water flow is strong, the water flows rapidly along the edges of the sealing cover 2. When the water flow is slow, the water along the edges of the sealing cover 2 flows along the guide slope 22 into the disinfection chamber, dissolving the disinfection tablet 4 and exerting its efficacy.

[0043] The disinfection chamber 3 includes a first side panel 31 and a second side panel 32 arranged in a V-shape and connected as one piece, as well as a first baffle 33 and a second baffle 34 disposed between the first and second side panels 31, 32 and used to block the disinfection tablets 4. The first and second side panels 31, 32 together form a ridge 35 on their bottom sides for breaking fluid pressure. The V-shaped structure of the first and second side panels 31, 32 forms a funnel-shaped cavity that is wide at the top and narrow at the bottom. When water enters the chamber, the cross-sectional contraction produces an acceleration effect, increasing the flushing force on the disinfection tablets 4 and improving the efficiency of drug dissolution. A drain hole 331 is provided on at least one of the first and second baffles 33, 34. The liquid from the dissolved disinfection tablets 4 flows through the drain hole 331 into the pipe and exerts its efficacy.

[0044] In this embodiment, the bottom of the sealing cover 2 is provided with a slot 23 near the edge for mounting the disinfection chamber 3. Both the first side panel 31 and the second side panel 32 have a flange 311 on their top sides for inserting into the slot 23. The slot 23 on the bottom of the sealing cover 2 and the flange 311 on the top side of the disinfection chamber 3 utilize a mortise and tenon joint fit. The slot width matches the flange 311 thickness, ensuring automatic alignment during insertion and enabling assembly and disassembly without tools.

[0045] In this embodiment, if disinfectant tablets 4 are used, which generate harmful gases, a relatively small amount of tablets 4 should be used. After water flows through, the chamber should be left to stand for a period of time (e.g., 1 hour) to allow the disinfectant tablets 4 to be completely consumed and the generated harmful gases to mix thoroughly with the fluid in the pipe, fully diluting the harmful effects of the toxic gases and improving the disinfection effect. This prevents toxic gases from escaping into the chamber when the sealing cover 2 is opened. The disinfectant tablets 4 will have evaporated by the next time the disinfectant chamber 3 is used, and no toxic gases will be generated.

[0046] If the disinfection tablets 4 that do not produce harmful gases are used, the amount of disinfection tablets 4 can be arbitrarily selected, and each time a small amount of water flows through, the disinfection effect can be achieved. Compared with the related art, in which the disinfection tablets 4 are placed on the upper layer of the floor drain, in this embodiment, the disinfection tablets 4 can be released evenly in batches, extending the service life.

[0047] The implementation principle of a floor drain disinfection embodiment of the present application is as follows: in the floor drain housing 1, the first sealing ring 14 between the outer housing 11 and the inner housing 12 forms a radial seal to prevent sewage leakage, and the second sealing ring 15 between the outer housing 11 and the connecting sleeve 13 adapts to the displacement of the pipeline and blocks odors through axial extrusion. The telescopic rod structure 16 has a built-in magnetic block. During drainage, the impact force of the water flow overcomes the magnetic force to open the channel. After drainage is completed, the magnetic force drives the sealing cover 2 to rise and fit tightly with the bottom of the inner housing 12. The convex and concave matching of the sealing guide surface 21 and the inclined guide surface 121 enhances the sealing accuracy. In the negative pressure environment of the pipeline, zero leakage is achieved with the assistance of atmospheric pressure.

[0048] The diversion slope 22 on the bottom side of the sealing cover 2 extends to the edges on both sides. When the flow rate is large, the water flows quickly, and when the flow rate is small, the water flows along the diversion slope 22 into the disinfection cabin 3. The first and second side panels 32 form a funnel-shaped cavity to accelerate the flushing of water and guide the water to converge in the center. The water droplet 331 is opened on the baffle to ensure that the dissolved liquid medicine flows into the pipeline to achieve the elimination of pests. The disinfection cabin 3 is connected to the mortise and tenon of the convex edge 311 through the insertion groove body 23 to achieve tool-free quick disassembly and assembly. For strong disinfection tablets 4, the system controls the amount of dosage, uses water flow to dilute the toxic gas, and uses pipeline fluid mixing to further reduce the harmfulness. For agents without harmful gases, it is allowed to be dosed on demand to achieve long-term disinfection.

[0049] Example 2 Reference Figure 6 This embodiment differs from Embodiment 1 in the method of movable connection between the disinfection chamber 3 and the sealing cover 2. In this embodiment, a hinge seat 312 is provided on one side of the bottom of the sealing cover 2 for hinged connection of the first side panel 31. A buckle 24 is provided on the side of the bottom of the sealing cover 2 away from the hinge seat 312 for connection of the second side panel 32. The second side panel 32 has a slot 321 on the top side for the buckle 24 to engage.

[0050] One side of the disinfection cabin 3 is hinged to the sealing cover 2, and the other side is fixed with the card slot 321 through the buckle 24 to form a flip-up opening and closing structure. The dual fixing method of the hinge seat 312 and the buckle 24 ensures that the disinfection cabin 3 is firmly connected to the sealing cover 2 during normal use. The hinged setting makes the opening and closing process of the disinfection cabin 3 smooth, avoiding the displacement of the internal medicine due to shaking. The close fit between the buckle 24 and the card slot 321 provides a reliable locking force in the closed state to prevent the disinfection cabin 3 from accidentally opening due to water impact or vibration. During maintenance, the user only needs to press the buckle 24 to disengage it from the card slot 321, and then the disinfection cabin 3 can be opened like turning a book, which is convenient for quickly putting in or replacing the disinfection tablets 4.

[0051] Example 3 Reference Figure 7 This embodiment differs from Embodiment 1 in that the guide slope 22 on the bottom side of the sealing cover 2 is disposed differently. In this embodiment, the sealing cover 2 is provided with two guide slopes 22 on the bottom side. The two guide slopes 22 are spaced apart, with one end of each guide slope 22 extending to the edge of the sealing cover 2 and the other end located at the center of the sealing cover 2.

[0052] The water diversion efficiency of a single diversion slope 22 is limited by its slope width and inclination angle, resulting in low water diversion efficiency. The dual diversion slopes 22 increase the flow rate of water entering the disinfection chamber per unit time, improving water diversion efficiency. The two diversion slopes 22 simultaneously guide water into the disinfection chamber 3, ensuring sufficient water flow contacts the disinfection tablets 4 and preventing ineffective rinsing of the disinfectant.
