A toilet cleaning fluid supply device and toilet that prevents residual liquid.

Abstract

This invention discloses a toilet cleaning fluid supply device and toilet that prevents residual liquid, relating to the field of toilet accessory technology, including a storage tank for storing cleaning fluid. This toilet cleaning fluid supply device and toilet, which prevents residual liquid, mixes cleaning water and cleaning fluid through a diversion component, allowing the cleaning fluid and cleaning water to fully contact and generate foam before discharge. The mixed water flow rinses the inner wall of the toilet seat once, and then a sealing mechanism seals the outlet pipe. At this time, the mixed water flow performs internal self-flushing along the diversion component, the supply pipe, and the mixing mechanism, preventing residual cleaning fluid from each discharge, thus avoiding insufficient cleaning fluid concentration and pipe blockage. Finally, releasing the sealing mechanism allows a small portion of the water mixed with cleaning fluid to perform a secondary rinsing of the inner wall of the toilet seat, ensuring that the cleaning fluid supply device can thoroughly clean the inner wall of the toilet seat.

Description

Technical Field

[0001] This invention relates to the field of toilet accessories technology, specifically to a toilet cleaning fluid supply device and toilet that prevents residual liquid. Background Technology

[0002] There are generally two ways to clean a toilet. The first is to add the cleaning agent to the toilet tank and then flush the toilet to rinse the toilet bowl with the mixed cleaning solution. The second is to spray the cleaning agent onto the toilet bowl and let it sit for a while before flushing.

[0003] In existing technologies, many methods involve introducing cleaning solution from a designated container along a pipe into the water tank, where the water flow carries the cleaning solution to flush the toilet bowl. However, because the conventional method involves directly feeding the cleaning solution into the water tank and then flushing it into the toilet bowl, the water flow is insufficient to fully cover the toilet bowl's inner walls. Furthermore, during the entire cleaning solution supply process, residues can remain inside the pipes. This can cause cleaning solution to clog the pipes in toilets that are not frequently used, and the concentration of the prepared cleaning solution may not meet the intended specifications. Summary of the Invention

[0004] The purpose of this invention is to provide a toilet cleaning fluid supply device and toilet that prevents residual liquid, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a toilet cleaning liquid supply device for preventing residual liquid, comprising a storage tank for storing cleaning liquid, wherein the bottom of the storage tank is connected to a liquid delivery pump for quantitatively drawing the cleaning liquid, and the output pipe of the liquid delivery pump is connected to a liquid supply pipeline for discharging the cleaning liquid.

[0006] The lower part of the liquid supply pipeline is connected to a diversion component that separates the cleaning water and the cleaning liquid. The diversion component is equipped with a mixing mechanism that allows the cleaning liquid and the cleaning water to come into full contact. The diversion component includes an upper box and a lower box that are fastened by screws. The upper box and the lower box are connected to water inlet pipes on both sides for supplying cleaning water. The bottom center of the lower box is connected to a water outlet pipe.

[0007] The drainage component is equipped with a sealing mechanism that slides to seal the straight pipe. The sealing mechanism switches the water flow from the outlet pipe to open and close. When the outlet pipe is sealed, the mixed water flow backflows into the supply pipe to flush away any residual cleaning liquid.

[0008] Preferably, the liquid supply pipe route consists of a manifold, a branch pipe, and a straight pipe, wherein the two sides of the manifold are connected to the branch pipe, and the bottom end of the manifold is sealed to the straight pipe;

[0009] A water-proof sleeve is welded to the outside of the straight pipe. Through holes are opened at both the upper and lower ends of the straight pipe near the inner wall of the water-proof sleeve, and the water flow in the water-proof sleeve is connected to the straight pipe through the through holes. A threaded joint is movably connected to the bottom end of the diversion pipe.

[0010] Preferably, the upper surface of the upper box body is connected to the threaded joint of the diversion pipe, and the top center of the upper box body is fixed to the straight pipe.

[0011] Preferably, the mixing mechanism includes premixing chambers symmetrically arranged on the sides of the upper and lower boxes that fit together, and a movably connected wheel is installed inside the premixing chamber;

[0012] A central cavity is provided in the center of the side where the upper and lower boxes fit together. The central cavity in the upper box is connected to the straight pipe, and the central cavity in the lower box is connected to the water outlet pipe.

[0013] Preferably, the swivel wheel is composed of a hollow wheel body and a baffle fixed to the outer periphery of the hollow wheel body;

[0014] The top of the hollow wheel body has a round hole corresponding to the threaded connector of the diverter pipe, and the outer circumference of the hollow wheel body has a liquid throwing port. The clean water introduced into the premixing chamber by the water inlet pipe pushes the baffle of the throwing wheel, so that the rotating throwing wheel rotates in the premixing chamber.

[0015] Preferably, the premixing chamber and the central chamber are connected by a curved groove, and the water flowing out from the curved groove rushes into the central chamber along the inner wall edge. The port of the curved groove connecting the central chamber is cylindrical.

[0016] Preferably, the premixing chamber and the central chamber are connected by a second bend, and the water flowing out from the second bend rushes into the central area of ​​the central chamber. The port of the second bend connecting the central chamber is funnel-shaped.

[0017] Preferably, the sealing mechanism includes a fixed pipe that is vertically fixed to the water outlet pipe, and the fixed pipe and the straight pipe are arranged on the same axis. A vertical rod with a sealing ring on its surface slides inside the fixed pipe.

[0018] The vertical rod slides against the inner wall of the fixed pipe through a sealing ring on its surface to prevent water from seeping downwards. The vertical rod is equipped with a conical plug and a plunger that are inserted into the central cavity and the inside of the straight pipe.

[0019] Preferably, a spiral plate is fixed to the outer periphery of the fixed tube, and an annular plate coaxially distributed with the fixed tube is integrally formed at the bottom end of the spiral plate;

[0020] Below the fixed tube is a drive sleeve that is fixed to the bottom end of the vertical rod, and the top wall of the drive sleeve is fixed with an extrusion rod. The top edge of the extrusion rod is embedded with a roller that fits against the bottom wall of the spiral plate.

[0021] Spring 1 and Spring 2 are connected to the outer and inner sides of the drive sleeve, respectively. A motor is installed below the drive sleeve. The motor is matched and plugged into the drive sleeve through the prism-shaped output rod at the top. The bottom end of Spring 1 abuts against the top wall of the motor, and the bottom end of Spring 2 abuts against the top of the prism-shaped output rod of the motor.

[0022] A toilet includes a water tank and a toilet seat. A storage tank is fitted inside the water tank on one side. The toilet seat is located at the bottom of the water tank. A liquid pump, a liquid supply pipeline, a drainage component, and a sealing mechanism are all located in the toilet seat.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the toilet cleaning liquid supply device and toilet that prevent residual liquid use mix cleaning water and cleaning liquid through the diversion component, which allows the cleaning liquid and cleaning water to come into full contact before discharge to generate foam. The mixed water flow is used to rinse the inner wall of the toilet seat, and then the outlet pipe is blocked by the sealing mechanism. At this time, the mixed water flow will perform internal self-flushing along the diversion component, the liquid supply pipe and the mixing mechanism, avoiding the generation of residual cleaning liquid each time it is discharged, which would cause insufficient cleaning liquid concentration and pipe blockage. Finally, by releasing the sealing mechanism, a small amount of water mixed with cleaning liquid is allowed to perform a second coverage rinse on the inner wall of the toilet seat, ensuring that the cleaning liquid supply device can thoroughly clean the inner wall of the toilet seat.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: See Figure 1 , Figure 2 , Figures 4-6 and Figure 10 This invention provides a toilet cleaning liquid supply device to prevent residual liquid, including a storage tank 1 for storing cleaning liquid. The top of the storage tank 1 is hinged with a sealing cover 101. By flipping the sealing cover 101 hinged to the storage tank 1, the storage tank 1 can be opened or sealed, thereby facilitating cleaning, maintenance and adding cleaning liquid. The bottom of the storage tank 1 is connected to a liquid delivery pump 2 for quantitatively drawing cleaning liquid. The output pipe of the liquid delivery pump 2 is connected to a liquid supply pipeline 3 for discharging cleaning liquid.

[0037] The liquid supply pipeline 3 consists of a manifold 301, a branch pipe 302, and a straight pipe 303. The branch pipe 302 is connected to both sides of the manifold 301. The bottom end of the manifold 301 is sealed to the straight pipe 303. A water-proof sleeve 304 is welded to the outside of the straight pipe 303. Through holes 305 are opened at both the upper and lower ends of the straight pipe 303 near the inner wall of the water-proof sleeve 304. The water flow in the straight pipe 303 and the water-proof sleeve 304 is connected through the through holes 305. A threaded joint is movably connected to the bottom end of the branch pipe 302. The manifold 301, branch pipe 302, straight pipe 303, and water-proof sleeve 304 are made of stainless steel.

[0038] In this embodiment, the cleaning liquid inside the storage tank 1 can be quantitatively drawn by starting the liquid delivery pump 2, and the drawn cleaning liquid is sent into the manifold 301 of the liquid supply pipeline 3, and the cleaning liquid will be diverted and discharged along the two diversion pipes 302.

[0039] Please see Figures 1-6 Below the liquid supply line 3 is a diversion assembly 4 that separates the cleaning water and the cleaning liquid. The diversion assembly 4 is equipped with a mixing mechanism 6 that ensures full contact between the cleaning liquid and the cleaning water. The diversion assembly 4 includes an upper box 401 and a lower box 402 that are fastened by screws. The upper box 401 and the lower box 402 are sealed together with sealant. The upper box 401 and the lower box 402 are connected to the sides of the upper box 401 and the lower box 402 with inlet pipes 403 for supplying cleaning water. The bottom center of the lower box 402 is connected to an outlet pipe 404. The upper surface of the upper box 401 is connected to the threaded joint of the diversion pipe 302, and the top center of the upper box 401 is fixed to the straight pipe 303.

[0040] In this embodiment, the threaded connector of the diversion pipe 302 is threadedly connected to the upper box 401, thereby introducing the cleaning liquid into the interior of the upper box 401 and the lower box 402 through the diversion pipe 302, and then introducing the cleaning water into the water inlet pipe 403, so that the cleaning water is flushed into the interior of the upper box 401 and the lower box 402 from both sides.

[0041] Please see Figure 3 , Figure 5 and Figure 6 The mixing mechanism 6 includes a premixing chamber 601 symmetrically opened on the sides of the upper box 401 and the lower box 402 that are in contact with each other. A swing wheel 604 is movably connected inside the premixing chamber 601. A central cavity 602 is opened in the center of the sides of the upper box 401 and the lower box 402 that are in contact with each other. The central cavity 602 located in the upper box 401 is connected to the straight pipe 303, and the central cavity 602 located in the lower box 402 is connected to the water outlet pipe 404.

[0042] In this embodiment, the cleaning water that flows into the premixing chamber 601 from the inlet pipe 403 pushes the impeller 604, causing it to rotate within the premixing chamber 601. The rotating impeller 604 can send the water flow from the premixing chamber 601 into the central chamber 602, thereby facilitating the convergence of the water flow from the two premixing chambers 601 into the central chamber 602.

[0043] Please see Figure 3 and Figure 6 The swivel wheel 604 consists of a hollow wheel body and a baffle fixed to the outer periphery of the hollow wheel body. The top of the hollow wheel body has a round hole corresponding to the threaded joint of the diversion pipe 302, and the outer periphery of the hollow wheel body has a liquid-swiping port. The clean water introduced into the premixing chamber 601 by the water inlet pipe 403 pushes the baffle of the swivel wheel 604, so that the rotating swivel wheel 604 rotates in the premixing chamber 601.

[0044] In this embodiment, the cleaning fluid introduced from the diversion pipe 302 into the upper box 401 and the lower box 402 will be introduced along the round hole at the top of the hollow wheel body. When the baffle of the swivel wheel 604 is squeezed by the cleaning water, the swivel port of the hollow wheel body will centrifugally throw out the cleaning fluid and mix it with the cleaning water flowing in the premixing chamber 601.

[0045] Please see Figure 8 A curved groove 603a connects the premixing chamber 601 and the central chamber 602. Water flowing from the curved groove 603a rushes into the central chamber 602 along the inner wall edge. The port of the curved groove 603a connecting the central chamber 602 is cylindrical. Water flowing from the premixing chamber 601 into the curved groove 603a will rush into the cylindrical port of the curved groove 603a. At this time, the water flowing to the two ports of the curved groove 603a will generate vortex flow along the inner wall of the central chamber 602, thereby enabling the cleaning water and cleaning liquid to be mixed twice in the central chamber 602, ensuring that the cleaning water and cleaning liquid are in full contact.

[0046] Please see Figure 1 , Figure 2 as well as Figures 4-7 The drainage assembly 4 is equipped with a sealing mechanism 5 for slidingly sealing the straight pipe 303. The sealing mechanism 5 includes a fixed pipe 501 that is vertically fixed on the water outlet pipe 404, and the fixed pipe 501 and the straight pipe 303 are arranged on the same axis. A vertical rod 502 with a sealing ring on its surface slides inside the fixed pipe 501. The vertical rod 502 slides against the inner wall of the fixed pipe 501 through the sealing ring on its surface to prevent water from seeping downward. A conical plug 503 and a plunger 504 are provided on the vertical rod 502 and inserted into the central cavity 602 and the straight pipe 303.

[0047] In this embodiment, the control rod 502 drives the plunger 504 to slide and insert at the connection between the straight pipe 303 and the manifold 301, so that the straight pipe 303 and the manifold 301 are not connected to each other. At the same time, the conical plug 503 is located in the center of the central cavity 602. When the water flowing from the premixing cavity 601 to the central cavity 602 converges, a small portion of the water will rush upward into the straight pipe 303 and fill the water-proof sleeve 304 along the through hole 305. Most of the water will be discharged downward along the water outlet pipe 404 at the bottom of the lower box 402.

[0048] When the control rod 502 drives the plunger 504 to slide downwards from the connection between the straight pipe 303 and the manifold 301, the central cavity 602, the straight pipe 303, the water-proof sleeve 304, and the manifold 301 will gradually become connected. At the same time, when the conical plug 503 moves downwards from the center of the central cavity 602 and blocks the upper port of the outlet pipe 404, the water flowing from the premixing chamber 601 into the central cavity 602 will flow along the premixing chamber 601 when they converge. The mixing chamber 601 is pushed upward into the straight pipe 303, and then enters the water-proof sleeve 304 through the through hole 305 at the lower end of the straight pipe 303. Subsequently, it re-enters the upper end of the straight pipe 303 through the through hole 305 at the upper end of the straight pipe 303, so that the water flow is guided upward into the manifold 301 and the branch pipe 302, thereby flushing the cleaning fluid inside the liquid supply line 3 and preventing residual cleaning fluid from remaining in the liquid supply line 3 on the output side of the liquid pump 2.

[0049] Please see Figure 1 , Figure 2 as well as Figures 4-7 A spiral plate 505 is fixed to the outer periphery of the fixed tube 501. An annular plate coaxial with the fixed tube 501 is integrally formed at the bottom end of the spiral plate 505. A drive sleeve 508 fixed to the bottom end of the vertical rod 502 is provided below the fixed tube 501. A pressing rod 510 is fixed to the top wall of the drive sleeve 508. A roller that fits against the bottom wall of the spiral plate 505 is embedded in the top edge of the pressing rod 510. Spring 1 507 and spring 2 509 are respectively connected to the outer and inner sides of the drive sleeve 508. A motor 506 is provided below the drive sleeve 508. The motor 506 is matched and inserted into the drive sleeve 508 through the prism-shaped output rod at the top. The bottom end of spring 1 507 abuts against the top wall of the motor 506, and the bottom end of spring 2 509 abuts against the top of the prism-shaped output rod of the motor 506.

[0050] In this embodiment, the starting motor 506 drives the prism-shaped output rod and the drive sleeve 508 to rotate. The rotating drive sleeve 508 can drive the vertical rod 502 and the extrusion rod 510 to rotate. The rotating extrusion rod 510 will roll and stick to the bottom wall of the spiral plate 505 through the roller embedded in the top edge. When the roller at the top of the extrusion rod 510 rolls along the upper end of the spiral plate 505 to the bottom end of the spiral plate 505, the drive sleeve 508 will move downward and compress the spring 1 507 and the spring 2 509. At this time, the downward-moving drive sleeve 508 will pull the vertical rod 502 to drive the conical plug 503 and the plunger 504 to move downward synchronously, so that the conical plug 503 that has moved down to the position can temporarily block the water flow discharged to the water outlet pipe 404 and make the water flow back into the liquid supply pipe 3 to achieve anti-residue cleaning.

[0051] When the rotating extrusion rod 510 moves from the bottom wall of the spiral plate 505 to the annular plate outside the fixed pipe 501 via the roller, the vertical rod 502 will continuously drive the conical plug 503 to block the upper port of the water outlet pipe 404.

[0052] When the rotating extrusion rod 510 disengages from the end of the annular plate via the rollers and moves toward the top of the spiral plate 505, the drive sleeve 508 is quickly reset upward by the reset push of the spring 507 and the spring 509. This causes the conical plug 503 and the plunger 504 on the vertical rod 502 to move upward. At this time, the plunger 504 can re-seal the connection between the manifold 301 and the straight pipe 303, preventing the water from flowing upward and affecting the downward flow of the cleaning fluid. The conical plug 503 moves back to the center of the central cavity 602, making it easier for the water mixed with the cleaning fluid to be discharged outward from the outlet pipe 404.

[0053] Please see Figure 10 A toilet includes a water tank 7 and a toilet seat 8. A storage tank 1 is fitted inside the water tank 7 on one side. The toilet seat 8 is provided at the bottom of the water tank 7. A liquid pump 2, a liquid supply pipeline 3, a drainage component 4 and a sealing mechanism 5 are all provided in the toilet seat 8.

[0054] In this embodiment, the storage tank 1 is installed separately inside the water tank 7, so that the water tank 7 and the storage tank 1 store cleaning water and cleaning liquid respectively, thereby separating the cleaning water and cleaning liquid. When it is necessary to rinse the inner wall of the toilet seat 8, the cleaning liquid and cleaning water are mixed by the liquid delivery pump 2, the liquid supply pipeline 3 and the drainage component 4 and then introduced into the toilet seat 8 for cleaning.

[0055] Example 2: See Figure 9This embodiment of the invention differs from Embodiment 1 in that: a second bend 603b connects the premixing chamber 601 and the central chamber 602. Water flowing from the second bend 603b rushes into the central region of the central chamber 602. The port of the second bend 603b connecting the central chamber 602 is funnel-shaped. Water flowing from the premixing chamber 601 into the second bend 603b will rush into the funnel-shaped port of the second bend 603b. At this time, the water flowing to the two ports of the second bend 603b will create a countercurrent towards the central region of the central chamber 602. The counter-current of water flow disperses the undispersed cleaning solution in the water and allows the cleaning water and cleaning solution to mix twice in the central cavity 602. At the same time, the counter-current of water flow can accelerate the generation of foam in the cleaning solution, and the funnel-shaped curved groove 603b port can increase the counter-current area of ​​the water flow. Thus, by generating foam at the inlet position of the water outlet pipe 404, the foam of the cleaning solution can cover the toilet wall, eliminating the need for the cleaning solution to generate foam in the cleaning water in advance, and thus not affecting the discharge speed after the cleaning solution and water are mixed.

[0056] Working principle: When the water tank 7 on the toilet seat 8 is driven to drain, the cleaning water will flow into the upper box 401 and the lower box 402 on both sides through the two water inlet pipes 403 respectively. Then, the liquid pump 2 draws the cleaning liquid in a certain amount and sends it into the liquid supply line 3, so that the cleaning liquid is diverted to the impeller 604 in the premixing chamber 601. The impeller 604, which is pushed and rotated by the cleaning water, can initially mix the cleaning liquid with the water. When the mixed water flows into the central chamber 602, a secondary mixing contact can be achieved. After the cleaning liquid and the cleaning water have completed the mixing contact, it will be discharged outward from the water outlet pipe 404.

[0057] When the liquid pump 2 stops delivering cleaning fluid, the motor 506 drives the drive sleeve 508 to rotate the vertical rod 502 and the squeezing rod 510. At this time, the squeezing rod 510 and the spiral plate 505 make squeezing contact, which enables the drive sleeve 508 to move the vertical rod 502 downward. As a result, the vertical rod 502 moves the conical plug 503 and the plunger 504 downward synchronously. When the conical plug 503 blocks the upper port of the water outlet pipe 404, the water flowing into the central cavity 602 will flow backward along the liquid supply pipe 3, which can flush the residual cleaning fluid in the liquid supply pipe 3 and allow all the residual cleaning fluid to be introduced into the upper box 401 and the lower box 402. When the motor 506 drives the squeezing rod 510 to rotate one revolution, the vertical rod 502 drives the conical plug 503 and the plunger 504 to move upward and reset, which allows the remaining water to be discharged into the toilet seat 8 along the water outlet pipe 404 to achieve a complete flushing operation.

[0058] In the process of rinsing the toilet seat 8 with the above-mentioned mixed cleaning solution and cleaning water, the inner wall of the toilet seat 8 is first rinsed by the mixed water flow. Then, the water flow of the outlet pipe 404 is switched on and off by the sealing mechanism 5. When the outlet pipe 404 is sealed, the mixed water flow is backflowed into the liquid supply pipe 3 to flush away the residual cleaning solution. The flushing water flow will perform internal self-flushing along the drainage component 4, the liquid supply pipe 3 and the mixing mechanism 6 to avoid the generation of residual cleaning solution each time it is discharged, which would cause insufficient cleaning solution concentration and pipe blockage. Finally, the sealing mechanism 5 is released to allow a small amount of water mixed with cleaning solution to perform a second flushing of the inner wall of the toilet seat 8, so that the inner wall of the toilet seat 8 is thoroughly cleaned. The contents not described in detail in this description are prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
