Description

Delayed release method of toilet cleaner

Technical Field

The invention relates to the field of putting in of a toilet bowl cleaning agent, in particular to a method for releasing a toilet cleaning agent in a delayed mode.

Background

In both domestic and public health areas, the toilet bowl needs to be cleaned, deodorized, etc., so as to ensure the sanitation of the toilet bowl and the environmental sanitation. The common treatment methods can be divided into two types: firstly, effective substances such as cleaning substances or aromatic substances are placed in a water tank of a flush toilet and are gradually dissolved in the water tank, when the flush toilet is flushed, water with the effective substances enters the flush toilet from the water tank to flush the inner wall of the flush toilet, cleaning is realized, and part of the effective substances remained in the water in the flush toilet send out the aromatic substances, so that the environment is improved; secondly, effective substances, such as solid block or gelatinous paste, are directly pasted inside the closestool, and after water in the water tank enters the closestool, the solid block or gelatinous substance is washed while the inner wall of the closestool is washed, so that the aim of cleaning or removing peculiar smell is fulfilled. The two modes need manual operation for placing or change new effective substances in a short period so as to realize the purpose of continuously treating the flush toilet, and when the two modes are operated by hands, some corrosive or easily dyed substances can be stained on the hands, so that inconvenience and even injury are brought to users.

For the first common treatment method, the effective substance is soaked in the water tank for a long time, and is in a continuous dissolving state no matter whether the toilet is used or not, so that the dissolution of the effective substance is accelerated, and when the dissolved water in the water tank is used for flushing the inner wall of the toilet, a large amount of the dissolved water flows away from a sewer, and only a small part of the dissolved water is remained in the toilet. In summary, the active substance has a short life and is not related to the number of uses of the toilet bowl, and the active substance is mostly wasted.

For the second common treatment mode, in order to avoid the large block of effective substances from being washed away and lost, the solvent speed of the solid substances is slow, when water in the water tank flows through the effective substances adhered to the inner wall of the closestool, the obtained effective components in the dissolved water are insufficient, most of the dissolved water can enter a sewer, the amount of the dissolved water remained in the closestool is small, waste is caused, and on the other hand, the concentration of the effective substances in the dissolved water is extremely low, so that the expected effects of cleaning, peculiar smell removal treatment and the like cannot be achieved.

Therefore, the existing means for cleaning and deodorizing the toilet bowl have the defects of excessive or insufficient or uneven release of effective substances or large loss of the effective substances, and waste is caused and the ideal effect is far from achieved.

Disclosure of Invention

The invention aims to overcome at least one defect of the prior art and provides a method for releasing the toilet cleaner in a delayed manner, which can release an initial solution formed by the toilet cleaner and water in a delayed manner, ensure the content of effective substances of the toilet cleaner in a toilet basin, enable most of the solution to stay in a toilet, reduce waste and improve the practical effect.

The invention adopts the technical scheme that a method for releasing a toilet cleaning agent in a delayed manner acts on a toilet basin of a flush toilet, wherein the toilet cleaning agent is arranged in the toilet basin, and the method comprises the following steps: the water in the toilet bowl enters, the water and the toilet cleaner are mixed to form an initial solution, the initial solution starts to be released, the water level in the toilet bowl returns to a normal state, the initial solution is continuously released after the water level in the toilet bowl returns to the normal state until the release is finished, and the mixed liquid of the initial solution and the water in the toilet bowl is called as primary solution.

The method of the invention is mainly applied to a water closet, more particularly to a water closet bowl, the water closet bowl is connected with a U-shaped pipe between a sewer pipe, and the water composition in the water closet bowl and the U-shaped pipe is approximately equal after a user flushes the water closet each time. In addition, most toilets are provided with water replenishing pipes, the effect of the water replenishing pipes is that water is directly introduced into a toilet bowl through the water replenishing pipes synchronously in the process of discharging water of a toilet water tank and recovering the water level of the water tank, the water level of the toilet bowl is kept stable, the difference of water level height caused by the inertia effect of water drainage of the toilet bowl can not be generated in the water level in the toilet bowl, and the water replenishing of the toilet bowl and the toilet water tank is finished simultaneously. Secondly, the initial solution formed by dissolving the toilet cleaner in the toilet bowl is very small relative to the water storage volume in the toilet bowl, when the water replenishing is stopped in the toilet bowl or the toilet water tank, the influence of the release of the initial solution on the water level in the toilet bowl is negligible, and the condition that the water replenishing stopping in the toilet bowl or the toilet water tank is equal to the condition that the water level in the toilet bowl is restored to the normal state can be determined. For the closestool without the water replenishing pipe, the water level in the toilet bowl can be determined to be restored to the normal state as long as the water level in the toilet bowl of the last closestool is not obviously increased. When the technical scheme is used, the toilet cleaner is fixed on the inner wall of the toilet bowl, when a user presses a water outlet button on the flush toilet, a water outlet valve in the water tank is opened, and water in the water tank enters the toilet bowl through the opening on the edge of the toilet bowl. Water closets can be broadly divided into two categories according to the different water outlet directions of the toilet bowls, namely, a water closet with a vertical water outlet of the toilet bowl or a water closet with a horizontal water outlet of the toilet bowl. No matter the structure of the toilet bowl is adopted, the toilet bowl needs to be mixed with water energy and a toilet cleaning agent, wherein the toilet cleaning agent can be granular and is packaged by a water-permeable bag, such as a non-woven fabric bag and the like. When water and the toilet cleaner are mixed, an initial solution can be formed, along with the lengthening of the mixing time, the content of effective solute of the toilet cleaner in the initial solution is higher and higher, and the later released initial solution contains higher solute; secondly, when the toilet cleaner is required to be dissolved for a certain time to form an initial solution with higher concentration and then released, the dissolving speed or the uniform mixing speed of the toilet cleaner can be controlled.

When the initial solution is released, the water level in the toilet bowl gradually rises, and finally returns to the normal state when the toilet is not flushed, meanwhile, the water surface in the toilet bowl gradually tends to calm, and then the initial solution is continuously released for a period of time until the water and the toilet cleaner are mixed to form the initial solution and the release is finished. In this stage, the time period from the time point when the water level in the toilet bowl returns to the normal state to the time point when the initial solution is completely released is the delayed release time of the toilet cleaner. By controlling the dissolution speed of the initial solution, the time required for dissolution is properly prolonged, so that the solute quantity of the toilet cleaner which is dissolved at the initial flushing stage and is directly flushed away is reduced; and under the certain condition of initial solution volume, time delay release for the volume of toilet cleaner solute in the initial solution is retained in the lavatory basin is higher, that is to say, avoids solution to be taken away by rivers at the bath process, makes a large amount of stops of solution in the closestool, has reduced the waste, and guarantees solution concentration and result of use in the lavatory basin.

Further, in the method, the time for mixing water and the toilet cleaning agent to form the initial solution is defined as t 2; the time from the beginning to the end of the release of the initial solution is defined as the initial solution outflow time t3, during the actual use process, the toilet cleaner is filled in a container with a fixed volume, the toilet cleaner starts to dissolve and release the initial solution when water enters the container, and the dissolution is finished when the water is released completely. When the water forms an initial solution with the toilet cleaner and is immediately released, t2 is t 3.

Further, in the method, the recovery normality of the water level in the toilet bowl from the beginning of the water entering the toilet bowl is defined as the flushing time t1 of the toilet; defining the delayed release time t4 of the initial solution part from the normal state recovery of the water level in the toilet bowl to the completion of the initial solution release; then t 4-t 3-t 1. In the in-service use process, the toilet cleaner can be adorned in the container of a fixed volume, therefore, the water volume that gets into in the container is certain, before the water level does not resume the normality in the lavatory basin, the initial solution concentration that flows into in the lavatory basin is less, along with water in the container is less and less, and dissolve or dilute the time of toilet cleaner more and more long, the initial solution concentration that flows into in the lavatory basin is more and more high, can guarantee like this that the water level resumes the normality in the lavatory basin after, the initial solution concentration that flows into the lavatory basin at last is the highest, make the effective material of toilet cleaner in the lavatory basin stop in the closestool most, and the waste is reduced.

Further, defining the delayed release time t4 of the initial solution part from the normal return of the water level in the toilet bowl to the completion of the initial solution release, t4 is more than or equal to 3 minutes, and/or t4 is more than or equal to t 1. After the existing closestool in the market is flushed and pressed once, the time t1 that water in a water tank tends to calm from flowing out to the inner water surface of a closestool basin is 5-120 seconds, so that the content of the initial solution remained in the closestool basin is improved, namely the content of solute in the primary solution is improved, and the initial solution is released after the inner water surface of the closestool basin tends to calm as much as possible; secondly, along with the increase of the service life of the flush toilet, the water outlet valve in the water tank is loosened and aged, after the flush toilet is pressed once, the time for water flow to flow into the toilet bowl from the water tank is obviously prolonged, namely the time required by the water level in the toilet bowl tends to be calm is increased, and therefore the initial solution is set for at least 3 minutes after the flush is finished. Secondly, when the toilet bowl begins to feed water, water and the toilet cleaner are mixed to form initial solution and begin to release, therefore, the time period from the initial solution beginning to release to the initial moment of the delayed release time t4 is basically as long as the toilet flushing time t1, in order to ensure that after the initial solution is released, the content of effective components in the sequential solution existing in the toilet bowl is as much as possible, t4 is set to be more than or equal to t1, namely the time of delayed release of the initial solution is not less than the toilet flushing time t1, and along with the longer and longer time of dissolving the toilet cleaner, the concentration of the initial solution is higher and higher, so that at least 50% of the initial solution can stay in the toilet bowl, namely at least 50% of the content of the effective substances of the initial solution in the toilet bowl can stay in primary solution, and the solute of the toilet cleaner can stay in the toilet bowl as much as possible.

Further, the time from the beginning to the end of the release of the initial solution is defined as the initial solution flowing time t3, then t3 is less than or equal to 40 minutes, and/or t3 is more than or equal to 2t 1. T4 is t3-t1, t1 is 5 to 120 seconds, and t4 is not less than 3 minutes, so t3 is preferably 4 to 25 minutes. According to the volume of the initial solution, the release speed of the initial solution is controlled to adjust the time for completely releasing the initial solution, the use frequency of the closestool in different occasions is considered, the time from the beginning to the end of the release of the initial solution is set to be 4-25 minutes, so that the initial solution can be fully released during the continuous two-time use of the closestool, the sufficient solute contained in the solution entering the toilet basin every time is ensured, and the use effect of the toilet cleaner is improved. Secondly, t3 is more than or equal to 2t1 as t4 is t3-t1 and t4 is more than or equal to t1, so that the time length t4 for delayed release of the initial solution is not less than the flushing time t1 of the toilet, and the concentration of the initial solution is higher and higher along with longer and longer time for dissolving the toilet cleaner, so that at least 50% of the initial solution stays in the toilet bowl, namely at least 50% of the effective substance content of the initial solution in the toilet bowl exists in the primary solution, and the solute of the toilet cleaner stays in the toilet bowl as much as possible.

Further, the solute content m1 of the primary solution is related to the solute content m0 of the initial solution by: m1/m0 is 0.5-1.

The water storage volumes of the toilet bowls of different sizes are different, but the initial solution formed by the toilet cleaner of the same type in time t2 has a certain volume, namely the solute content m0 of the initial solution is certain. The solute acts in the toilet bowl and is substantially the solute in the primary solution, and in order to ensure the action effect of the primary solution in the toilet bowl, the solute content ratio is adopted for measurement, namely m1/m0 is 0.5-1; preferably, m1/m0 is 0.5 or 0.6 or 0.7 or 0.8 or 0.9 or 1. As the toilet bowl is communicated with the U-shaped pipe, a small amount of solute inevitably enters the U-shaped pipe, and therefore, the ratio of m1/m0 is required to be more than 0.5. The steps in actual detection are as follows: selecting two identical toilets (a toilet A and a toilet B), cleaning a toilet water tank and a toilet bowl, filling the toilet water tank with water, and recovering the water level in the toilet bowl to a normal state; two identical cavities (a and b) are respectively mounted at the same positions of two toilets, and the cavity at the position can be connected with water flowing into a toilet bowl from a toilet tank; respectively putting the same solid toilet cleaner containing the cleaning component M and having the same mass into the cavities a and b; when the chamber a mounted on the toilet bowl a starts to release the initial solution by pressing the flush button of the toilet bowl a, the initial solution released from the chamber a is completely received by using the container, and the mass M in the initial solution received by the container is measured and recorded as M0. When the cavity B mounted on the closestool B finishes releasing the initial solution by pressing a flushing button of the closestool B, measuring the mass of M in the primary solution in the toilet bowl, and recording the mass as M1, thereby obtaining the ratio of M1/M0. The solute content in the initial solution and the primary solution with the same volume can be obtained by obtaining the initial solution and the primary solution with the same volume and adopting physical and chemical methods such as drying and the like, so that the actual ratio of m1 to m0 can be obtained, and the mixing ratio of the toilet cleaner and the water and the release amount of the initial solution can be adjusted.

Further, the toilet cleaner is placed in the cavity, and water is introduced into the cavity according to the structural characteristics of the toilet bowl and mixed with the toilet cleaner to form an initial solution.

In this technical scheme, place the toilet cleaner in the box body of taking the cavity, fix the box body at closestool lavatory basin border with the box body again, for avoiding the box body to influence the user and use the closestool, box body structure size is less, and at this moment, the water after the bath can not flow into the cavity smoothly, consequently, need be with water leading-in cavity in, make it mix with toilet cleaner smoothly and form initial solution.

Further, when the lavatory basin goes out water for vertical play, when no water got into in the cavity, the toilet cleaner was located the bottom in the cavity under the dead weight effect, and water is guided into from the upper portion of cavity by drainage slant downstream, dissolves or dilutes the toilet cleaner, flows out from the cavity bottom after forming initial solution.

When the lavatory basin goes out water for vertical play, the water that gets into the lavatory basin from the toilet bowl water tank promptly flows in along lavatory basin inner wall downwards, because the rivers flow downwards along the inner wall, therefore, set up the water inlet of cavity on upper portion, and towards lavatory basin inner wall, get into rivers from inner wall drainage downwards and lean on in the cavity on the inner wall, mix with the toilet cleaner of bottom in the cavity, dissolve or dilute toilet cleaner, increase along with the volume that water got into the cavity, the sufficient of cavity internal water, toilet cleaner or suspension are in the cavity, or continue to be located the cavity bottom, finally all can form and flow out from the cavity bottom after initial solution. In the process, the long and thin drainage tube is arranged at the bottom of the cavity or the long and thin water outlet channel is arranged at the bottom of the cavity, and the drainage tube is slowly released under the action of liquid tension, so that the time delay effect is realized.

Further, when the water outlet of the toilet basin is horizontal water outlet, when no water enters the cavity, the toilet cleaning agent is positioned at the bottom of the cavity under the action of self weight, and the water is guided to move upwards in an inclined mode by the drainage and is guided into the cavity from the upper part of the cavity to be mixed with the toilet cleaning agent at the bottom of the cavity, so that the toilet cleaning agent is dissolved or diluted to form initial solution and then flows out from the bottom of the cavity.

When the water outlet of the toilet bowl is horizontal water outlet, namely the water of the water tank of the flush toilet enters the toilet bowl from 1 to 2 water outlets horizontally arranged at the edge of the toilet bowl, the water can be transversely flushed out when flushing, and a vortex is formed along the wall of the toilet bowl under the action of gravity, so that the flushing force of the water flow on the wall of the toilet bowl is increased. Therefore, by adopting the oblique upward drainage mode, the transversely flushed water flow enters the cavity along with the increase of the water entering the cavity, the water in the cavity is full, the toilet cleaning agent is suspended in the cavity or continuously located at the bottom in the cavity, the toilet cleaning agent is dissolved or diluted, and finally the initial solution is formed and then flows out of the bottom of the cavity.

Further, the concentration or solute content of the initial solution is gradually increased between the time when the volume of the initial solution in the cavity reaches the maximum and the time when the release of the initial solution is completed.

Further, the concentration or solute content of the initial solution is gradually increased from the time when the volume of the initial solution reaches the maximum to the time when the release of the solution is completed.

When the toilet cleaner in the cavity is in a dry state before water enters the cavity for the first time, the concentration of the solution in the cavity is zero at the moment when water enters the cavity; when the toilet cleaner in the cavity is in a wet state before water enters the toilet cleaner for the second time or more, the initial solution in the cavity is remained in the cavity last time, and at the moment, the concentration of the solution in the cavity has a certain initial value. As water gradually enters the cavity, the gradual dissolution dilutes the toilet cleaner to form an initial solution, which is subsequently released from the cavity. The overall trend of the concentration of the initial solution is gradually increasing between the instant when water enters the chamber and the instant when the initial solution starts to be released, point tx.

When water in the flush toilet just enters the cavity, the toilet cleaning agent is in a solid state and is placed at the bottom of the cavity, a certain weight exists, when buoyancy generated by the amount of water entering the cavity is smaller than the self gravity of the toilet cleaning agent, the toilet cleaning agent blocks an outlet at the bottom of the cavity, the toilet cleaning agent is gradually dissolved in the period, and the concentration of initial solution liquid in the cavity is continuously increased; when the buoyancy generated by the water quantity entering the cavity is larger than the self gravity of the toilet cleaner, the toilet cleaner begins to leave the bottom outlet, but the water in the cavity is continuously injected, and the concentration of the initial solution liquid in the cavity is continuously reduced in the stage; finally, when no water enters the cavity, the outflow quantity of the water in the initial solution from the bottom is far less than the injection quantity of the water in the cavity, at the moment, the toilet cleaner is continuously dissolved in the water in the cavity, at the moment, the concentration of the initial solution flowing out from the bottom of the cavity begins to rise again, and therefore the concentration of the initial solution in the cavity changes to rise firstly and then fall and rise. In the actual experiment process, the toilet cleaner is placed in the cavity, two drops of liquid are collected from the bottom of the cavity at intervals, and the effective content of the toilet cleaner is measured.

Compared with the prior art, the drainage method is suitable for common direct-flushing toilets or siphon toilets by arranging different drainage methods, can release the initial solution formed by the toilet cleaner and water in a delayed manner, avoids the solution from being taken away by water flow in the flushing process, ensures the content of effective substances of the toilet cleaner in a toilet basin, enables a large amount of solution to stay in the toilet, improves the effectiveness of the toilet cleaner, prolongs the service life of the toilet cleaner with the same amount, and reduces waste.

Detailed Description

The drawings are only for purposes of illustration and are not to be construed as limiting the invention. For a better understanding of the following embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Example 1

The embodiment provides a method for releasing a toilet cleaning agent in a delayed manner, wherein the method acts in a toilet basin of a flush toilet, the toilet cleaning agent is arranged in the toilet basin, and the method comprises the following steps: the water enters the toilet bowl, the water and the toilet cleaner are mixed to form an initial solution, the initial solution starts to be released, the water level in the toilet bowl returns to a normal state, the initial solution is continuously released until the release is finished, and the mixed liquid of the initial solution and the water existing in the toilet bowl is called as a primary solution.

The method of the invention is mainly applied to a water closet, more particularly to a water closet bowl, the water closet bowl is connected with a U-shaped pipe between a sewer pipe, and the water composition in the water closet bowl and the U-shaped pipe is approximately equal after a user flushes the water closet each time. When using this embodiment, fix the cleaning agent at the lavatory basin inner wall, when the user pressed the play water button on the toilet, the outlet valve door in the water tank was opened, and the water in the water tank passes through the trompil at lavatory basin edge and gets into in the lavatory basin. Water closets can be broadly divided into two categories according to the different water outlet directions of the toilet bowls, namely, a water closet with a vertical water outlet of the toilet bowl or a water closet with a horizontal water outlet of the toilet bowl. No matter the toilet bowl with the structure is adopted, the water energy is required to be mixed with the toilet cleaning agent, the toilet cleaning agent can be in a solid form or a granular form, and the toilet cleaning agent is packaged by a water-permeable bag, such as a non-woven fabric bag. When water is mixed with the toilet cleaner, an initial solution can be formed, the content of effective solute of the toilet cleaner in the initial solution is higher and higher along with the lengthening of the mixing time, and the content of solute in the initial solution released later is higher; secondly, when the toilet cleaner is required to be dissolved for a certain time to form an initial solution with higher concentration and then released, the dissolving speed or the uniform mixing speed of the toilet cleaner can be controlled.

The water storage volumes of the toilet bowls of different sizes are different, but the initial solution formed by the toilet cleaner of the same type in time t2 has a certain volume, namely the solute content m0 of the initial solution is certain. The solute acts in the toilet bowl and is substantially the solute in the primary solution, and in order to ensure the action effect of the primary solution in the toilet bowl, the solute content ratio is adopted for measurement, namely m1/m0 is 0.5-1; preferably, m1/m0 is 0.5 or 0.6 or 0.7 or 0.8 or 0.9 or 1. As the toilet bowl is communicated with the U-shaped pipe, a small amount of solute inevitably enters the U-shaped pipe, and therefore, the ratio of m1/m0 is required to be more than 0.5. The steps in actual detection are as follows: selecting two identical toilets (a toilet A and a toilet B), cleaning a toilet water tank and a toilet bowl, filling the toilet water tank with water, and recovering the water level in the toilet bowl to a normal state; two identical cavities (a and b) are respectively mounted at the same positions of two toilets, and the cavity at the position can be connected with water flowing into a toilet bowl from a toilet tank; respectively putting the same solid toilet cleaner containing the cleaning component M and having the same mass into the cavities a and b; when the chamber a mounted on the toilet bowl a starts to release the initial solution by pressing the flush button of the toilet bowl a, the initial solution released from the chamber a is completely received by using the container, and the mass M in the initial solution received by the container is measured and recorded as M0. When the cavity B mounted on the closestool B finishes releasing the initial solution by pressing a flushing button of the closestool B, measuring the mass of M in the primary solution in the toilet bowl, and recording the mass as M1, thereby obtaining the ratio of M1/M0. The solute content in the initial solution and the primary solution with the same volume can be obtained by obtaining the initial solution and the primary solution with the same volume and adopting physical and chemical methods such as drying and the like, so that the actual ratio of m1 to m0 can be obtained, and the mixing ratio of the toilet cleaner and the water and the release amount of the initial solution can be adjusted. Further, the toilet cleaner 3 is placed in the cavity 2, and water is introduced into the cavity 2 according to the structural characteristics of the toilet bowl and mixed with the toilet cleaner 3 to form an initial solution.

In this embodiment, the toilet cleaner 3 is placed in the box body with the cavity 2, and the box body is fixed at the edge of the toilet bowl 1 of the toilet through the suspension device 4, so as to avoid the influence of the box body on the use of the toilet by users, the structural size of the box body is small, at this time, the water after flushing can not smoothly flow into the cavity 2, therefore, the water needs to be guided into the cavity 2, and the water and the toilet cleaner 3 are smoothly mixed to form the initial solution.

Further, as shown in fig. 1, when the water discharged from the toilet bowl 1 is vertical water, and no water enters the cavity 2, the toilet cleaner 3 is located at the bottom of the cavity 2 under the action of self weight, as shown by arrows in the figure, the water is guided to move downwards in a slant manner, and is guided in from the upper part of the cavity 2 to dissolve or dilute the toilet cleaner 3, and along with the increase of the amount of the water entering the cavity 2, the water in the cavity 2 is full, the toilet cleaner 3 is suspended in the cavity 2 or continuously located at the bottom of the cavity 2, and finally, the toilet cleaner can form initial solution and then flows out from a drainage hole at the bottom of the cavity 2.

When 1 play water in lavatory basin is vertical play water, the water that gets into lavatory basin 1 from the toilet bowl water tank promptly flows in along 1 inner wall in lavatory basin downwards, because the rivers flow downwards along the inner wall, consequently, set up the water inlet of cavity 2 on upper portion, and towards 1 inner wall in lavatory basin, with rivers from the inner wall drainage entering downwards lean on in cavity 2 on the inner wall, mix with the toilet cleaner 3 of bottom in the cavity 2, dissolve or dilute toilet cleaner 3, flow out from 2 bottoms of cavity after forming initial solution. In the process, the long and thin drainage tube is arranged at the bottom of the cavity 2 or the long and thin water outlet channel is arranged at the bottom of the cavity, and the drainage tube is slowly released under the action of liquid tension, so that the time delay effect is realized.

As shown in fig. 3, the concentration or solute content of the initial solution is gradually increased between the time when the volume of the initial solution in the cavity is maximized and the time when the initial solution is released. Or the concentration or the solute content of the primary solution is gradually increased from the moment when the volume of the initial solution reaches the maximum to the moment when the release of the initial solution is finished in the cavity.

In this embodiment, as shown by the solid line in fig. 4, 4g of the sample of the toilet cleaner is weighed into the water-permeable packaging bags, the packaging bags are placed into the cavity 2 of the mold 1 after being sealed, the volume of the cavity 2 is 20mL, the drainage time interval at the bottom of the cavity is measured to be 5.5min, 20mL of tap water is added into the cavity 2, then the time is immediately counted, and two drops of liquid discharged from the cavity 2 are collected at certain time intervals to test the solute content in the toilet cleaner, and the obtained results are as follows:

0.5	542
		1	623

1. A method for releasing a toilet cleaner in a delayed manner, wherein the toilet cleaner acts in a toilet bowl of a toilet bowl, and the toilet cleaner is arranged in the toilet bowl, is characterized by comprising the following steps:

the water in the toilet bowl enters, the water and the toilet cleaner are mixed to form an initial solution, the initial solution starts to be released, the water level in the toilet bowl returns to a normal state, the initial solution is continuously released after the water level in the toilet bowl returns to the normal state until the release is finished, and the mixed liquid of the initial solution and the water in the toilet bowl is called as primary solution.

2. A method for the extended release of a toilet cleaner according to claim 1, wherein, in said method,

defining the time t1 for flushing the toilet bowl when water enters the toilet bowl from the beginning and the water level in the toilet bowl returns to the normal state;

defining the time from the beginning to the end of the release of the initial solution as the initial solution flowing-out time t 3;

defining the delayed release time t4 of the initial solution part from the normal state recovery of the water level in the toilet bowl to the completion of the initial solution release; then t 4-t 3-t 1.

3. A method for the delayed release of a toilet cleaner according to claim 1 or 2, wherein the delayed release time t4 of the initial solution part from the return of the water level in the toilet bowl to the completion of the initial solution release is defined as t4 ≥ 3 minutes, and/or t4 ≥ t 1.

4. A method for the delayed release of a toilet cleaner according to claim 1 or 2, wherein the time from the beginning of the release of the initial solution to the completion of the release is defined as the initial solution outflow time t3, t3 is less than or equal to 40 minutes, and/or t3 is more than or equal to 2t 1.

5. The method for delaying the release of a toilet cleaner according to claim 4, wherein t3 is 4-25 minutes.

6. A method for extended release of a toilet cleaner according to claim 1 wherein the solute content m1 of the primary solution is related to the solute content m0 of the initial solution by: m1/m0 is 0.5-1.

7. A method of delaying the release of a toilet cleaner according to claim 1 or 2, wherein the toilet cleaner is placed in the chamber and water is introduced into the chamber and mixed with the toilet cleaner to form an initial solution according to the structural characteristics of the toilet bowl.

8. The method for releasing the toilet cleaner in a delayed manner as claimed in claim 7, wherein when the toilet bowl water outlet is a vertical water outlet, the water is guided to move downwards in a slant direction, and is guided in from the upper part of the cavity to dissolve or dilute the toilet cleaner, so that an initial solution is formed and then flows out from the bottom of the cavity; when the water discharged from the toilet basin is horizontal, the water is drained and moves upwards in an inclined mode, is guided in from the upper portion of the cavity, dissolves or dilutes the toilet cleaner, and flows out from the bottom of the cavity after initial solution is formed.

9. A method for the delayed release of a toilet cleaner according to claim 1 or 2, wherein the concentration of the initial solution or the solute content in the chamber is gradually increased from the time when the volume of the initial solution reaches the maximum to the time when the release of the initial solution is completed.

10. A method for the delayed release of a toilet cleaner according to claim 1 or 2, wherein the concentration of the primary solution or the solute content is gradually increased in the chamber from the time when the volume of the primary solution reaches the maximum to the time when the release of the primary solution is completed.
