Description

Technical Field

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

[0002] The disinfection drain is a new type of drain product with a disinfection chamber. The disinfection drain has a disinfection chamber and related components at the sealing cover of the drain to put disinfectant, thereby effectively killing bacteria and viruses, preventing odors from rising and pests from entering the room.

[0003] In related technologies, disinfection chambers are typically located above or in the middle of floor drains. They are relatively independent spaces used to hold disinfectant agents or install disinfection equipment such as ultraviolet lamps. Some disinfection chambers have removable covers or sealed doors for convenient periodic addition or replacement of disinfectant agents and maintenance of disinfection equipment.

[0004] Regarding the aforementioned technologies, the pesticide is placed above the floor drain for pest control. Typically, pest control requires the use of strong pesticides and professional handling. If the pesticide produces harmful gases, these gases can diffuse into the room and endanger human health. Therefore, there is a need for a type of floor drain that can hold strong pesticides for thorough pest control while preventing harmful gases from spreading indoors. Utility Model Content

[0005] In order to enable the floor drain to hold strong pesticides for thorough pest control while preventing harmful gases from spreading indoors, this application provides a pest control floor drain.

[0006] The technical solution for disinfecting floor drains provided in this application is as follows:

[0007] A disinfection drain includes a drain housing, a sealing cap for sealing the drain housing, and a telescopic rod structure for connecting the sealing cap and the drain housing;

[0008] The sealing cover has a disinfection chamber for holding disinfectant tablets at the bottom. The disinfection chamber has at least one drainage hole at the bottom. The sealing cover has a flow guide slope on the bottom side, and at least one end of the flow guide slope extends to the edge of the sealing cover.

[0009] By adopting the above technical solution, the disinfection chamber is located below the sealing cover, rather than above the drain, forming a relatively enclosed space. When a strong disinfectant is placed, the sealing cover, in conjunction with the drain housing, can block the harmful gases emitted by the agent, ensuring that the disinfectant primarily works inside the drain (or pipes), reducing the risk of gas diffusion into the room. The sealing cover and drain housing are connected by a telescopic rod structure, which allows the sealing cover to seal and open with the drain housing, thus preventing gas backflow from the pipes when sealed. The drain hole at the bottom of the disinfection chamber allows water flow to dissolve the disinfectant tablets, allowing the pesticide to enter the drain pipes with the water flow, disinfecting pests (such as cockroaches, moths, etc.) and their eggs within the pipes. The guide slope on the bottom side of the sealing cover extends to the edge. When the water flow is strong, the water flows rapidly along the edge of the sealing cover; when the water flow is slow, the water along the guide slope enters the disinfection chamber, dissolving the disinfectant tablets and evenly distributing the dissolved pesticide into the drain pipes, enhancing the thoroughness of pest control.

[0010] Furthermore, the number of the guide slopes is at least one.

[0011] By adopting the above technical solution, the number of guide slopes can be one or multiple. A single guide slope can effectively guide water flow from the edge of the sealed cover into the disinfection chamber, but its water guiding efficiency is limited by the slope width and inclination angle, resulting in low efficiency. Setting up multiple guide slopes increases the flow rate of water entering the disinfection chamber per unit time, thus improving water guiding efficiency. Multiple guide slopes can simultaneously guide water flow in different directions, ensuring sufficient water contact with the disinfection tablets and preventing ineffective rinsing of the disinfectant.

[0012] Furthermore, the disinfection chamber is movably connected to the lower side of the sealing cover.

[0013] By adopting the above technical solution, the movable disinfection chamber can be easily opened, closed, or disassembled from the bottom of the sealed cover, making it easy to add new disinfection tablets.

[0014] Furthermore, the disinfection chamber includes a first side plate and a second side plate arranged in a V-shape and integrally connected, as well as a first baffle and a second baffle disposed between the first side plate and the second side plate for blocking the disinfection tablet, and the drain hole is opened on the first baffle and / or the second baffle.

[0015] By adopting the above technical solution, the V-shaped structure of the first and second side plates forms a funnel-shaped cavity that is wider at the top and narrower at the bottom. When water flows into the chamber, the cross-sectional contraction creates an acceleration effect, enhancing the flushing force on the disinfectant tablets and improving the dissolution efficiency of the disinfectant. The V-shaped side plates guide the water flow towards the center, ensuring that the water flow evenly covers the disinfectant tablets, avoiding the excessively rapid local consumption of the disinfectant caused by water flow deviation in traditional rectangular chambers.

[0016] Furthermore, the bottom of the sealing cover is provided with an insertion slot for installing the disinfection chamber near the edge, and both the first side plate and the second side plate are provided with a protruding edge on the top side for inserting into the insertion slot.

[0017] By adopting the above technical solution, the insertion groove at the bottom of the sealing cover and the protrusion on the top side of the disinfection chamber are joined by a tenon and mortise joint. The width of the groove matches the thickness of the protrusion, ensuring automatic alignment during insertion. Disassembly and assembly can be completed without tools. Compared with the traditional screw fixing or overall disassembly method, the operation steps are greatly simplified and can be completed without tools, significantly improving maintenance efficiency and reducing the user's threshold for use.

[0018] Furthermore, the bottom of the sealing cover is provided with a hinge seat on one side for hinged connection of the first side plate, and the bottom of the sealing cover is provided with a buckle on the side away from the hinge seat for connection of the second side plate, and the second side plate is provided with a slot on the top side for the buckle to be engaged.

[0019] By adopting the above technical solution, one side of the disinfection chamber is hinged to the sealing cover, while the other side is fixed by a snap-fit ​​and a slot, forming a flip-top opening and closing structure. The dual fixing method of the hinge and the snap-fit ​​ensures that the disinfection chamber is firmly connected to the sealing cover during normal use. The hinge design makes the opening and closing process of the disinfection chamber smooth, preventing internal reagent displacement due to shaking. The tight fit between the snap-fit ​​and the slot provides reliable locking force in the closed state, preventing accidental opening of the disinfection chamber due to water flow impact or vibration. During maintenance, the user only needs to press the snap-fit ​​to disengage it from the slot, and the disinfection chamber can be opened like flipping a book, facilitating quick deployment or replacement of the disinfection tablet.

[0020] Furthermore, the drain housing includes an outer shell, an inner shell, and a connecting sleeve for sealing connection with the pipe. A first sealing ring is provided between the outer shell and the inner shell, and a second sealing ring is provided between the outer shell and the connecting sleeve.

[0021] By adopting the above technical solution, the first sealing ring is set at the joint between the outer shell and the inner shell to achieve a static seal between the outer shell and the inner shell. When the outer shell and the inner shell are assembled, the first sealing ring is compressed to form a radial seal, preventing sewage inside the drain from leaking through the shell gaps. The second sealing ring achieves a dynamic seal between the outer shell and the connecting sleeve when the connecting sleeve is connected to the drain pipe. The second sealing ring forms a seal through axial compression, which can adapt to slight pipe displacement or water flow impact vibration in high-rise drainage pipes, preventing air or water leakage at the pipe joint.

[0022] Furthermore, the telescopic rod structure includes an installation rod arranged along the diameter direction of the inner shell, a telescopic sleeve fixedly connected to the center position of the installation 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;

[0023] The telescopic rod has a first magnetic block embedded at its upper end, and the connecting sleeve has a second magnetic block for cooperating with the first magnetic block.

[0024] By adopting the above technical solution, the mounting rod is set along the diameter direction of the inner shell, providing lateral support for the telescopic rod. The nesting of the telescopic sleeve and the telescopic rod restricts the radial movement of the telescopic rod, ensuring its vertical lifting and lowering, and preventing the sealing cover from shaking or shifting during movement, thereby ensuring the sealing accuracy between the sealing cover and the drain shell. Even under the impact of high-flow drainage, the stable telescopic rod structure can maintain the normal movement trajectory of the sealing cover, ensuring the reliability of the sealing effect. The first magnetic block at the upper end of the telescopic rod and the second magnetic block inside the telescopic sleeve attract each other, forming a magnetic sealing mechanism. When drainage ends, the impact force of the water flow weakens, and the magnetic force drives the telescopic rod to automatically raise the sealing cover, tightly fitting it against the bottom of the drain shell, achieving rapid sealing and effectively preventing the rise of odors and harmful gases in the pipe. During drainage, the impact force of the water flow can overcome the magnetic attraction, pushing the telescopic rod down and opening the drainage channel. The automatic switching between drainage and sealing can be completed without manual operation, improving the convenience of use.

[0025] Furthermore, the sealing cover has a sealing guide surface at the edge of the top side for sealing with the lower edge of the inner housing, and the inner housing has an inclined guide surface on the inner wall near the lower end that cooperates with the sealing guide surface.

[0026] By adopting the above technical solution, the sealing guide surface is set on the top edge of the sealing cover, and is usually 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 that the sealing surface is evenly pressurized, and avoiding local air leakage caused by installation deviations in traditional flat seals. After drainage, 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.

[0027] Furthermore, the first side plate and the second side plate together form a protruding ridge on the bottom side for relieving fluid pressure.

[0028] By employing the above technical solution, the instantaneous vacuum generated during drainage creates negative pressure in the pipe, producing an upward suction force that hinders the descent of the sealing cap. The protruding ridges, located on the bottom side of the disinfection chamber, trigger fluid boundary layer separation as water flows through, generating turbulent vortices. This turbulence converts the negative pressure energy within the pipe into fluid kinetic energy, reducing the peak negative pressure and thus decreasing the suction force on the sealing cap, ensuring its normal descent and drainage under the impact of water flow.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The disinfection drain, by placing the disinfection chamber below the sealed cover, forms an independent, enclosed space, preventing the diffusion of harmful gases from the volatilized pesticide into the room, thus avoiding threats to human health at the source. The drainage hole at the bottom of the disinfection chamber works in conjunction with the flow-guiding slope on the bottom side of the sealed cover. When the water flow is slow, the flow-guiding slope guides the water into the disinfection chamber to dissolve the pesticide, allowing the solution to penetrate deep into the pipes and kill cockroaches, moths, and other pests and their eggs. When the water flow is heavy, most of the water flows directly along the edge of the sealed cover, reducing excessive pesticide dissolution, ensuring both disinfection effectiveness and pesticide waste. The number of flow-guiding slopes can be flexibly set according to the usage scenario. A single slope can achieve basic water guiding function, while multiple slopes can simultaneously guide water flow in different directions, accelerating diversion during high-volume drainage and ensuring full contact between the pesticide and the water flow.

[0031] 2. The V-shaped arrangement of the two side plates, combined with the double baffles, creates a funnel-shaped cavity in the disinfection chamber, accelerating the water flow and extending the contact time between the water and the pesticide. This allows the pesticide to fully dissolve and distribute evenly throughout the pipes, achieving thorough eradication of pests. The protruding ridges on the bottom of the disinfection chamber can break the negative pressure in the pipes, reducing the suction force of the negative pressure on the sealing cap. This allows the sealing cap to descend normally under the impact of the water flow, solving the problem of poor drainage caused by negative pressure.

[0032] 3. The disinfection chamber can adopt a hinged seat and buckle flip-top connection structure, or a tenon and mortise structure with insert slot and protrusion. Both installation structures can be quickly opened and disassembled without tools, which is convenient for regular dosing or replacement of agents. The modular design of each component reduces the difficulty and cost of maintenance. Attached Figure Description

[0041] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-7 Examples 1, 2 and 3 will be used to further describe this application in detail.

[0042] Example 1

[0043] This application discloses a disinfection drain. (Refer to...) Figure 1 and Figure 2 The disinfection drain includes a drain housing 1, a sealing cap 2, and a disinfection chamber 3. The sealing cap 2 seals the bottom of the drain housing 1, thereby isolating the gas inside the pipe and preventing odorous gases from flowing back. The disinfection chamber 3 is located below the sealing cap 2 and is used to fill with disinfectant tablets 4, thereby eliminating pests inside the pipe.

[0044] Combination Figure 3 The drain housing 1 includes an outer shell 11, an inner shell 12, and a connecting sleeve 13 for sealing connection with a pipe. A first sealing ring 14 is provided between the outer shell 11 and the inner shell 12. The first sealing ring 14 provides a static seal between the outer shell 11 and the inner shell 12 at the joint. When the outer shell 11 and the inner shell 12 are assembled, the first sealing ring 14 is compressed to form a radial seal, preventing sewage from leaking from the gaps between the housings. A second sealing ring 15 is provided between the outer shell 11 and the connecting sleeve 13. The second sealing ring 15 provides a dynamic seal 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 forms a seal through axial compression, which can adapt to slight pipe displacement or water flow impact vibration in high-rise drainage pipes, preventing air or water leakage at the pipe joint.

[0045] The inner housing 12 has a telescopic rod structure 16 near its upper end for connecting the sealing cover 2. The telescopic rod structure 16 includes a mounting rod 161, a telescopic sleeve 162, and a telescopic rod 163. The mounting rod 161 is arranged along the diameter direction of the inner housing 12 and is integrally connected to the inner housing 12. The telescopic sleeve 162 is fixedly connected to the center position of the lower side of the mounting rod 161. The telescopic rod 163 is slidably installed in the connecting sleeve 13. The sealing cover 2 is fixedly connected to the lower end of the telescopic rod 163.

[0046] A first magnetic block 164 is embedded in the upper end of the telescopic rod 163, and a second magnetic block 165 is provided inside the telescopic sleeve 162 for cooperating with the first magnetic block 164. The first magnetic block 164 and the second magnetic block 165 attract each other to form a magnetic sealing mechanism. When drainage ends, the impact force of the water flow weakens, and the magnetic force drives the telescopic rod 163 to automatically raise the sealing cover 2, which fits tightly against the bottom of the drain housing 1, achieving a rapid seal and effectively preventing odors and harmful gases from rising from the pipe. During drainage, the impact force of the water flow can overcome the magnetic attraction force, pushing the telescopic rod 163 down to open the drainage channel. The automatic switching between drainage and sealing can be completed without manual operation, improving the convenience of use.

[0047] Combination Figure 4 The sealing cover 2 has a sealing guide surface 21 at the edge of its top side for sealing with the lower edge of the inner housing 12. The inner housing 12 has an inclined guide surface 121 on its inner wall near the lower end that cooperates with the sealing guide surface 21.

[0048] Reference Figure 5 The sealing cover 2 has a flow guide slope 22 on its bottom side, with both ends of the flow guide slope 22 extending to the two side edges of the sealing cover 2. The disinfection chamber 3 is movably connected to the lower side of the sealing cover 2. When the water flow is large, the water flows rapidly along the edge of the sealing cover 2; when the water flow is slow, the water along the two side edges of the sealing cover 2 enters the disinfection chamber along the flow guide slope 22, causing the disinfection tablets 4 to dissolve and exert their medicinal effect.

[0049] The disinfection chamber 3 includes a first side plate 31 and a second side plate 32 arranged in a V-shape and integrally connected, as well as a first baffle 33 and a second baffle 34 disposed between the first side plate 31 and the second side plate 32 to block the disinfection tablet 4. The first side plate 31 and the second side plate 32 together form a protruding rib 35 on the bottom side to relieve fluid pressure. The V-shaped structure of the first side plate 31 and the second side plate 32 forms a funnel-shaped cavity that is wider at the top and narrower at the bottom. When water flows into the chamber, the cross-sectional contraction generates an acceleration effect, which enhances the flushing force on the disinfection tablet 4 and improves the dissolution efficiency of the agent. At least one of the first baffle 33 and the second baffle 34 has a drain hole 331. The liquid after the disinfection tablet 4 is dissolved flows into the pipe through the drain hole 331 and exerts its effect.

[0050] In this embodiment, the bottom of the sealing cover 2 is provided with an insertion slot 23 for installing the disinfection chamber 3 near the edge. The first side plate 31 and the second side plate 32 are both provided with a protruding edge 311 on the top side for inserting the insertion slot 23. The insertion slot 23 at the bottom of the sealing cover 2 and the protruding edge 311 on the top side of the disinfection chamber 3 are engaged by a tenon and mortise joint. The width of the slot matches the thickness of the protruding edge 311 to ensure automatic alignment during insertion, and disassembly and assembly can be completed without tools.

[0051] In this embodiment, if a disinfectant tablet 4 that generates harmful gases is used, the dosage of the disinfectant tablet 4 needs to be controlled to a small extent. After water flows through, it needs to be left to stand for a period of time (e.g., 1 hour) to allow the disinfectant tablet 4 to be completely consumed and to ensure that the generated harmful gases are fully mixed with the fluid in the pipeline, thus fully diluting the harmfulness of the toxic gases and improving the disinfection effect. This prevents toxic gases from escaping into the room when the sealed cover 2 is opened. When the disinfection chamber 3 is used next time, the disinfectant tablet 4 will have completely evaporated and will not generate toxic gases.

[0052] If a disinfectant tablet 4 that does not produce harmful gases is used, the dosage of the disinfectant tablet 4 can be arbitrarily selected, and a disinfection effect can be produced each time a small flow of water passes through. Compared with related technologies, where the disinfectant tablet 4 is placed on top of the drain, in this embodiment, the disinfectant tablet 4 can be released evenly each time, extending the service life.

[0053] The implementation principle of a disinfection drain according to an embodiment of this application is as follows: In the drain housing 1, the first sealing ring 14 between the outer shell 11 and the inner shell 12 forms a radial seal to prevent sewage leakage. The second sealing ring 15 between the outer shell 11 and the connecting sleeve 13 adapts to pipe displacement and blocks odors through axial compression. The telescopic rod structure 16 has a built-in magnetic block. When draining, the impact force of the water flow overcomes the magnetic force to open the channel. After draining, the magnetic force drives the sealing cover 2 to rise and fit tightly against the bottom of the inner shell 12. The convex and concave fit between the sealing guide surface 21 and the inclined guide surface 121 enhances the sealing accuracy. Under the negative pressure environment of the pipeline, zero leakage is achieved with the assistance of atmospheric pressure.

[0054] The guide slope 22 on the bottom side of the sealing cover 2 extends to both sides. At high flow rates, the water flows rapidly, while at low flow rates, the water flows along the guide slope 22 into the disinfection chamber 3. The first and second side plates 32 form a funnel-shaped cavity, accelerating the water flow and guiding it towards the center. A drain hole 331 is located on the baffle plate to ensure the dissolved pesticide flows into the pipe, achieving pest control. The disinfection chamber 3 is connected to the insert slot 23 by a tenon joint with the raised edge 311, allowing for tool-free quick assembly and disassembly. For highly toxic disinfectant tablets 4, the system controls the dosage, dilutes the toxic gas with water flow, and further reduces hazard through pipe fluid mixing. For agents without harmful gases, on-demand dosing is allowed for long-lasting disinfection.

[0055] Example 2

[0056] Reference Figure 6 The difference between this embodiment and Embodiment 1 lies in the different movable connection method between the disinfection chamber 3 and the sealing cover 2. In this embodiment, the bottom of the sealing cover 2 is provided with a hinge seat 312 on one side for hinged connection of the first side plate 31, and the bottom of the sealing cover 2 is provided with a buckle 24 for connection of the second side plate 32 on the side away from the hinge seat 312. The second side plate 32 is provided with a slot 321 on the top side for the buckle 24 to be engaged.

[0057] The disinfection chamber 3 is hinged to the sealing cover 2 on one side, and fixed to the other side by a snap fastener 24 and a slot 321, forming a flip-top opening and closing structure. The dual fixing method of the hinge seat 312 and the snap fastener 24 ensures that the disinfection chamber 3 is securely connected to the sealing cover 2 during normal use. The hinge design makes the opening and closing of the disinfection chamber 3 smooth, preventing internal reagent displacement due to shaking. The tight fit between the snap fastener 24 and the slot 321 provides reliable locking force in the closed state, preventing accidental opening of the disinfection chamber 3 due to water flow or vibration. During maintenance, the user only needs to press the snap fastener 24 to disengage it from the slot 321, allowing the disinfection chamber 3 to be opened like flipping a book, facilitating quick deployment or replacement of the disinfection tablet 4.

[0058] Example 3

[0059] Reference Figure 7 The difference between this embodiment and Embodiment 1 is that the arrangement of the flow guide slope 22 on the bottom side of the sealing cover 2 is different. In this embodiment, the sealing cover 2 is provided with two flow guide slopes 22 on the bottom side. The two flow guide slopes 22 are arranged at intervals. Each flow guide slope 22 has one end extending to the edge of the sealing cover 2, and the other end is located at the center of the sealing cover 2.

[0060] The water guiding efficiency of a single guide slope 22 is limited by the slope width and inclination angle, resulting in low efficiency. The installation of two guide slopes 22 increases the flow rate of water entering the disinfection chamber per unit time, thus improving water guiding efficiency. The two guide slopes 22 simultaneously guide water into the disinfection chamber 3, ensuring sufficient water flow to contact the disinfection tablets 4 and preventing ineffective rinsing of the disinfectant.
