Description

Technical Field

[0001] This invention relates to the field of toilet cleaning technology, specifically to a reusable dispenser that is installed inside a toilet tank and can release cleaning agents in a quantitative and quantitative manner. Background Technology

[0002] Automatic toilet cleaning products are essential for maintaining cleanliness and hygiene in modern homes and public places. Currently, the most common automatic toilet cleaning products on the market are automatic toilet bowl blocks and automatic toilet bowl bottles.

[0003] Automatic toilet bowl cleaners are solid cleaning products containing detergents, fragrances, dyes, disinfectants, slow-release agents, and cleaning aids. When placed in the toilet tank, the solid cleaning components slowly dissolve in the water under the action of the slow-release agent, automatically cleaning the toilet and eliminating odors with each flush. However, toilet bowl cleaners have the following drawbacks in actual use: (1) Due to the encapsulation effect of the slow-release agent, the dissolution and release of the toilet bowl cleaner in water is uneven, with high concentration in the early stage and low concentration in the later stage, resulting in unstable cleaning effect; (2) When the toilet bowl cleaner is used, it is completely immersed in water, and its dissolution process is driven by the soaking time and flushing cycle. The fresh water added after each flush will dilute the concentration of detergent in the tank, driving the toilet bowl cleaner to continue to dissolve until the next flush. This mechanism causes the toilet bowl cleaner to continue to release during the flushing interval, and even if the toilet is not used, the cleaning components are still being consumed ineffectively, resulting in waste of cleaning materials.

[0004] While automatic toilet bowl cleaners have improved the problem of uneven concentration of toilet bowl cleaner blocks to some extent, most of them are single-use products. Users need to replace the entire toilet bowl cleaner bottle, which results in high usage costs. In addition, discarded toilet bowl cleaner bottles generate a lot of plastic waste, which is not in line with the concept of environmental protection.

[0005] To address the aforementioned issues, patent document CN113882486B discloses a slow-release toilet cleaner device, which includes a container holding solid cleaner. The container is connected to a water tank via a connecting pipe, and a shut-off valve on the connecting pipe is installed to control its opening and closing based on water level changes, achieving a function of no substance exchange when not in use. However, when using this device, the cleaner is directly placed into the container, and the relatively still water inside causes the solution near the surface of the toilet cleaner block to remain at a high concentration for a long time. Poorly soluble components (such as the slow-release agent skeleton and certain inorganic fillers) remain on the surface and gradually accumulate. After long-term use, a surface dissolved substance coating layer can easily form, causing uneven dissolution. Moreover, the lack of effective internal stirring makes it difficult to break the coating layer once it forms, and it may even block the connecting pipe. Furthermore, the cleaning dosage released each time is fixed, and users cannot adjust it according to their actual cleaning needs.

[0006] In addition, patent document CN214423501U discloses a floating toilet block pre-dissolving automatic quantitative release device, which achieves quantitative release by pre-dissolving to form a high concentration of toilet cleaning liquid, but it also has the problem of directly placing the cleaning agent and the amount of cleaning agent not being adjustable.

[0007] Therefore, it is necessary to propose further solutions to address the aforementioned technical problems. Summary of the Invention

[0008] The present invention provides a reusable quantitative and concentration-controlled release device to solve the above-mentioned technical problems.

[0009] Firstly, the objective of this invention is achieved through the following technical solution: a reusable quantitative and concentration-controlled release device, applied inside a toilet tank, comprising:

[0010] Solution tank;

[0011] A material bin, located inside the solution bin, is used to hold cleaning materials; the wall of the material bin is provided with multiple through holes to allow water from the solution bin to enter the material bin and dissolve the cleaning agent;

[0012] A metering and regulating device, in fluid communication with the solution tank, is used to meter and release the saturated cleaning solution flowing into the solution tank;

[0013] A one-way inlet valve, connected to the solution chamber, is used to allow external water to flow into the solution chamber when the water level in the toilet tank rises;

[0014] A discharge check valve, connected to the metering and regulating device, is used to allow a quantitative release of saturated cleaning solution from the metering and regulating device into the toilet tank when the water level in the toilet tank drops.

[0015] Furthermore, the metering adjustment device includes:

[0016] A metering and regulating chamber is located below and communicates with the solution chamber;

[0017] The discharge regulating pipe is height-adjustable and sealed to the bottom of the metering regulating chamber, and its discharge port is equipped with the discharge check valve;

[0018] By adjusting the insertion height of the discharge regulating pipe relative to the bottom of the metering regulating chamber, the effective volume of the metering regulating chamber can be changed, thereby adjusting the volume of solution discharged each time a flush is performed.

[0019] Furthermore, the discharge regulating pipe has an externally threaded tube formed on one side near the end of the pipe. It is installed on the discharge hole seat at the bottom of the metering regulating chamber by thread engagement. The insertion depth of the discharge regulating pipe relative to the bottom of the metering regulating chamber is adjusted by screwing the discharge regulating pipe to change the volume of the stored solution to be discharged and achieve quantitative regulation. The discharge regulating pipe is also fitted with a locking nut, which locks the discharge regulating pipe and presses against the lower end face of the discharge hole seat.

[0020] Furthermore, the discharge regulating pipe is a telescopic sleeve structure. By extending and retracting the discharge regulating pipe, its insertion depth relative to the bottom of the metering regulating chamber is adjusted to change the volume of the storage solution to be discharged, thereby achieving quantitative regulation.

[0021] Furthermore, an orifice plate with a flow regulating hole is provided at the connection between the solution tank and the metering regulating tank. The flow regulating hole is used to control the flow rate of the solution in the solution tank entering the metering regulating tank during discharge.

[0022] Furthermore, it also includes a support frame, through which the material bin is detachably suspended within the solution bin and located below the liquid surface; a gap is left between the bottom of the material bin and the bottom of the solution bin to facilitate solution flow.

[0023] Furthermore, it also includes: a hook seat, which is disposed on the outer wall of the solution chamber;

[0024] Install a height-adjustable hook, which is detachably attached to the hook base, for suspending the release device at different heights inside the toilet tank.

[0025] Furthermore, both the inlet check valve and the outlet check valve are spring-loaded or diaphragm-type check valves. When the water level in the toilet tank is stable and the internal and external pressures are balanced, both check valves are in the closed state.

[0026] Furthermore, the tops of the solution chamber and the material chamber are open.

[0027] Secondly, the present invention also provides a method for cleaning a toilet using the aforementioned release device, the method comprising the following steps:

[0028] Solid cleaning material is loaded into the material hopper;

[0029] Place the release device inside the toilet tank so that both the inlet check valve and the outlet check valve are submerged in water;

[0030] When the toilet tank is filled to full, external water enters the solution chamber through the inlet check valve and soaks the material chamber, dissolving the cleaning material to form a saturated cleaning solution. At this time, the outlet check valve closes.

[0031] When the toilet is flushed and the water level in the tank drops, the discharge check valve opens, releasing the quantitative saturated cleaning solution stored in the metering and regulating device into the water flow in the toilet tank. At the same time, the saturated cleaning solution in the solution chamber is replenished into the metering and regulating chamber of the metering and regulating device through the flow regulating hole.

[0032] The beneficial technical effects achieved by this invention are:

[0033] 1. Complete dissolution and no clogging: An independent material compartment is set up inside the solution chamber, and the wall of the material compartment has through holes to dissolve the detergent by submerging and soaking. This ensures that the concentration of the solution released each time remains constant, ensuring the stability of the toilet cleaning effect; on the other hand, it prevents the phenomenon of incomplete dissolution or material clogging the discharge pipe that can occur when the material is directly put into the solution chamber.

[0034] 2. Adjustable dosage and high flexibility: By setting up a metering adjustment chamber and an adjustable discharge pipe, users can change the amount of cleaning agent released each time they flush according to their actual cleaning needs by adjusting the height of the discharge pipe. This achieves true quantitative adjustment and avoids the limitations of fixed volume quantitative methods in existing technologies.

[0035] 3. No waste when not in use: Both the water inlet and outlet use one-way valves. When the toilet is not in use, both one-way valves are closed under pressure balance. There is no material exchange between the release device and the toilet tank. At the same time, the material stops dissolving after the solution in the solution chamber reaches saturation, effectively avoiding material waste.

[0036] 4. Easy installation and good versatility: The adjustable hook design allows users to easily adjust the suspension height of the release device according to the water level in the tank. It is simple to operate and adaptable to different models of toilet tanks.

[0037] 5. Simple structure and reusable: Users only need to replace the cleaning agent in the material bin periodically, and the releaser itself can be reused for a long time, which reduces the user's operating costs and is also beneficial to the environment. Attached Figure Description

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0045] Example 1

[0046] Please see Figure 1-5 This embodiment provides a reusable quantitative and concentration-controlled dispensing device for use in toilet tanks, including a solution chamber 1, a material chamber 2, a support 3, a hook seat 4, a hook 5, a metering and regulating chamber 6, an inlet one-way valve 7, a discharge regulating pipe 8, a discharge one-way valve 9, and an orifice plate 10. Wherein:

[0047] Solution tank 1 is a hollow container made of corrosion-resistant plastic, with an inlet 11 and an outlet 12. The inlet 11 is located on the side wall or bottom of solution tank 1; the outlet 12 is located at the bottom of solution tank 1. A one-way valve 7 is connected to the inlet 11 of solution tank 1 to allow external water to flow into solution tank 1 when the water level in the toilet tank rises.

[0048] Material chamber 2 is used to hold cleaning materials, which can be toilet cleaner blocks or cleaning granules. Material chamber 2 is detachably suspended inside solution chamber 1 by bracket 3 and is located below the liquid surface. The wall of material chamber 2 is provided with multiple through holes 21 to allow water from solution chamber 1 to enter material chamber 2, soaking and dissolving the cleaning materials, thereby forming a saturated cleaning solution around material chamber 2. The diameter of these through holes 21 is smaller than the diameter of the cleaning material particles to prevent the cleaning material particles from leaking out directly, while allowing water from solution chamber 1 to freely enter the interior of material chamber 2 to soak and dissolve the cleaning materials. Preferably, to facilitate solution flow, a gap is left between the bottom of material chamber 2 and the bottom of solution chamber 1.

[0049] A metering and regulating device, used to meter and release saturated cleaning solution flowing into the solution tank, includes a metering and regulating chamber 6 located below the solution tank 1 and a discharge regulating pipe 8 height-adjustable and sealed to the bottom of the metering and regulating chamber 6. The upper part of the metering and regulating chamber 6 is connected to the outlet 12 of the solution tank 1 via an orifice plate 10 with a flow regulating hole 12. The flow regulating hole 12 has a small diameter to limit the flow rate of the solution from the outlet 12 of the solution tank 1 into the metering and regulating chamber 6, preventing excessive filling.

[0050] like Figure 4 As shown, the discharge regulating pipe 8 has an externally threaded pipe 82b formed on the side near the end port 81. It is installed on the discharge hole seat 61 at the bottom of the metering regulating chamber 6 by thread engagement. By externally screwing the discharge regulating pipe 8, its insertion height relative to the bottom of the metering regulating chamber 6 can be adjusted, thereby changing the volume of solution discharged each time water is used. This achieves the goal of changing the volume of solution discharged each time water is used (i.e., the height of the top port 81 of the discharge regulating pipe 8 determines the critical water level at which the liquid begins to overflow). By adjusting the height of this top port 81, different discharge trigger points can be set. When water is used, the liquid in the metering regulating chamber 6 that is higher than the top of the discharge regulating pipe 8 flows out along the discharge regulating pipe 8. The liquid in the release device is continuously discharged due to the static pressure generated by the water tank flushing, until the liquid level in the metering regulating chamber 6 drops below the lower edge of the top port 81 of the discharge regulating pipe 8, at which point the discharge stops. A locking nut 83 is also fitted onto the discharge regulating pipe 8. After the locking nut 83 locks the discharge regulating pipe 8, it presses against the lower end face of the discharge hole seat 61, thus preventing the discharge regulating pipe 8 from loosening. The lowest end of the discharge regulating pipe 8 is provided with a discharge port, on which a discharge check valve 9 is installed. The discharge check valve 9 is used to allow a quantitative release of saturated cleaning solution in the metering regulating device into the toilet tank when the water level in the toilet tank drops.

[0051] A hook seat 4 and an adjustable hook 5 are also provided on the outer wall of the solution tank 1. The hook seat 4 is located on the outer wall of the solution tank 1. The adjustable hook 5 has multiple mounting holes at equal intervals along its height. A connecting column is axially fixed to the hook seat 4. The hook 5 is installed on the hook seat 4 by passing the connecting column through the mounting holes. This allows the entire release device to be suspended at different heights inside the toilet tank, ensuring that the inlet check valve 7 and the outlet check valve 9 are submerged in water when the tank is full.

[0052] In this embodiment, both the inlet check valve 7 and the outlet check valve 9 are diaphragm-type check valves. When the internal and external pressures are balanced or the external pressure is greater than the internal pressure, the valve remains closed under the action of the diaphragm. Specifically, when the water level in the toilet tank rises, creating a first pressure difference between the tank and the solution chamber 1, the diaphragm bends or deforms towards the outlet, and the inlet check valve 7 opens to allow water in; when the water level in the toilet tank drops, creating a second pressure difference between the metering and regulating device and the toilet tank, the outlet check valve 9 opens to release the solution.

[0053] It should be noted that in this embodiment, the tops of both the solution chamber 1 and the material chamber 2 are open. When the toilet cleaner blocks or cleaning granules in the material chamber 2 are used up, the user can directly place new toilet cleaner blocks or cleaning granules into the material chamber 2 without removing the release device, thus realizing the recycling of the release device.

[0054] The work process is as follows:

[0055] The dispenser is suspended inside the toilet tank via hook 5 and its height is adjusted. Once the tank is full, the external water pressure balances with the internal pressure of the dispenser, and both the inlet check valve 7 and the outlet check valve 9 are closed. At this time, the solid detergent in the material chamber 2 dissolves in the water, forming a saturated solution in the solution chamber 1. Simultaneously, the saturated solution slowly fills the entire metering regulating chamber 6 through the flow regulating hole 12 on the orifice plate 10. The volume of solution at the top of the outlet regulating pipe 8 is the measured amount of solution to be released in the next flush.

[0056] When the toilet is flushed, the water level in the tank drops rapidly, causing a sharp decrease in pressure outside the release valve. At this time, the saturated solution in the metering regulating chamber 6 generates static pressure due to the drop in the water level in the tank, which opens the discharge check valve 9. The metered saturated solution stored in the metering regulating chamber 6 (i.e., the solution at the top of the discharge regulating pipe 8) is then quickly released into the toilet tank through the discharge port and cleaned by the water flow.

[0057] After flushing, the water tank begins to replenish, and the water level gradually rises. As the external water pressure increases, external water is forced into solution chamber 1 through inlet check valve 7. Simultaneously, due to the increased external pressure, outlet check valve 9 closes. The fresh water entering solution chamber 1 replenishes the water consumed by dissolution and release, and continues to dissolve the detergent in material chamber 2, maintaining solution saturation. Meanwhile, the newly entering solution slowly refills metering regulating chamber 6 and outlet regulating pipe 8 through flow regulating orifice 12, preparing for the next flush. Flow regulating orifice 12 ensures that filling is slow, preventing excessive mixing of fresh water and saturated solution in solution chamber 1 during filling, thus ensuring that the concentration of solution in metering regulating chamber 6 remains close to saturation.

[0058] Example 2

[0059] This embodiment is basically the same as Embodiment 1, except that the adjustment method of the discharge regulating pipe 8 is different. Figure 5 As shown, in this embodiment, the end of the discharge regulating pipe 8 near the top opening 81 is a telescopic pipe structure 82a. By stretching or compressing the overall length of the telescopic pipe structure 82a, the insertion height of its top opening 81 within the metering regulating chamber 6 is changed, thereby altering the discharge trigger point to achieve quantitative regulation. This structure is also easy to operate and allows for stepless adjustment.

[0060] Example 3

[0061] This embodiment provides a method for cleaning a toilet using the release device described in the foregoing embodiment, the method comprising the following steps:

[0062] Load solid cleaning material into material bin 2;

[0063] Place the release device inside the toilet tank so that both the inlet check valve 7 and the outlet check valve 9 are submerged in water;

[0064] When the toilet tank is filled to full, external water enters the solution chamber 1 through the inlet check valve 7 and soaks the material chamber 2, dissolving the cleaning material to form a saturated cleaning solution. At this time, the outlet check valve 9 closes.

[0065] When the toilet is flushed and the water level in the tank drops, the discharge check valve 9 opens, releasing the quantitative saturated cleaning solution stored in the metering and regulating device into the water flow in the toilet tank. At the same time, the saturated cleaning solution in the solution chamber 1 is replenished into the metering and regulating chamber 6 of the metering and regulating device through the flow regulating hole 12.
