Description

Delayed release method of toilet cleaning product

Technical Field

The invention relates to the field of delivery of a toilet bowl cleaning agent, in particular to a method for releasing a toilet cleaning product 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 with cleaning or fragrance and the like are placed in a water tank of a flush toilet and are gradually dissolved in the water tank, when the toilet is flushed, water with the effective substances enters the toilet from the water tank to flush the inner wall of the toilet, so that cleaning is realized, and part of the effective substances remained in the water in the toilet emit fragrance, so that the environment is improved; secondly, effective substances, such as solid block or gel paste, are directly pasted inside the closestool, and when water in the water tank enters the closestool, the solid block or gel 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 delayed release method of a toilet cleaning product, which can release an initial solution formed by the toilet cleaning product and water in a delayed manner, ensure the content of effective substances of the toilet cleaning product 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 article in a delayed manner acts on a toilet bowl of a closestool, and the method comprises the following steps: water enters a toilet bowl, the water and the toilet cleaning articles 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 or part of residual liquid is remained, and the mixed liquid of the initial solution and the water existing in the toilet bowl is called primary solution; in the above method, the volume of the initial solution is not less than 10 ml; and the content of the effective components of the toilet cleaning product in the primary solution is not less than 2 ppm.

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 cleaning articles 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 using this technical scheme, fix the toilet articles for use at the lavatory basin inner wall, when the user pressed the water button on the toilet, the outlet valve door in the water tank was opened, and water in the water tank gets into in the lavatory basin through the trompil at lavatory basin edge. 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 which kind of structure's toilet is adopted, all need to make hydroenergy and toilet cleaning articles for use mix, the toilet cleaning articles for use here can be graininess, packs through the sack of water-permeable, like non-woven fabrics sack etc.. When water is mixed with the toilet cleaning product, an initial solution can be formed, along with the lengthening of the mixing time, the content of effective solute of the toilet cleaning product in the initial solution is higher and higher, and the later released initial solution contains higher solute; secondly, when the toilet cleaning product 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 cleaning product can be controlled to realize the purpose.

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 cleaning articles 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 released is the delayed release time of the toilet cleaning article. By controlling the dissolution speed of the initial solution, the time required for dissolution is properly prolonged, so that the dissolution quality of the toilet cleaning product 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 the cleaning toilet articles for use solute in 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, the solubility of the toilet article in the initial solution in water at 25 ℃ is not more than 10g/L, or the solubility of the toilet article in the initial solution in water at 20 ℃ is not more than 5 g/L.

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 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 water level in the toilet bowl returning to the normal state to the end of the initial solution release; then t 4-t 3-t 1. In the in-service use process, the toilet cleaning articles 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 cleaning articles 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 cleaning articles in the lavatory basin stop in the closestool, and the waste is reduced.

Further, defining the delayed release time t4 of the initial solution part from the water level in the toilet bowl returning to the normal state to the initial solution release end, 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 increased, namely the content of solute in the primary solution is increased, 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 to be released for at least 3 minutes after the flush toilet is finished. Secondly, when the toilet bowl begins to feed water, water and the toilet cleaning articles are mixed to form initial solution and begin to release, therefore, the time period from the initial solution beginning release time to the initial time 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 cleaning articles, 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 the primary solution, and the solute of the toilet cleaning articles 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-out 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 two continuous uses of the closestool, the fact that the solute contained in the solution entering the closestool basin at each time is sufficient is guaranteed, and the use effect of the toilet cleaning article 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 cleaning product, 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 cleaning product 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 cleaning products 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 shells (a and b) are respectively mounted at the same positions of two toilets, and the shell at the position can receive water flowing into a toilet bowl from a toilet water tank; respectively putting the same solid toilet cleaning articles with the same mass and containing the cleaning component M into the shell a and the shell b; when the initial solution is released from the casing a mounted on the toilet bowl a by pressing a flush button of the toilet bowl a, the initial solution released from the casing a is completely received by the container, and the mass M of the initial solution received by the container is measured and recorded as M0. When the shell 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 corresponding volumes can be obtained by obtaining the initial solution and the primary solution with certain volumes and adopting physical and chemical methods such as drying and the like, and the actual ratio of m1 to m0 can be obtained by calculating the solute content of the initial solution and the primary solution with the whole volumes, so that the mixing ratio of the toilet cleaning product and the water and the release amount of the initial solution can be adjusted.

Further, the toilet cleaning article is placed in the shell, and water is guided into the shell and mixed with the toilet cleaning article to form an initial solution according to the structural characteristics of the toilet bowl.

In this technical scheme, place the toilet articles for use in the box body of taking the casing, fix the box body at closestool lavatory basin border 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 casing smoothly, consequently, need with water leading-in casing in, make its and toilet articles for use smooth mixture form initial solution.

Further, when the lavatory basin goes out water for vertical play water, when no water got into in the casing, the toilet cleaning articles for use were located the bottom in the casing under the dead weight effect, and water is guided into from the upper portion of casing by drainage slant downstream, dissolves or dilutes toilet cleaning articles for use, flows out from the casing 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 casing on upper portion, and towards lavatory basin inner wall, get into to lean on in the inner wall upper shell from inner wall drainage downwards, mix with the toilet cleaning articles for use of bottom in the casing, dissolve or dilute toilet cleaning articles for use, increase along with the volume that water got into the casing, the filling of casing internal water, toilet cleaning articles for use or suspension are in the casing, or continue to be located the casing internal bottom, finally all can form and flow out from the casing behind the initial solution. In the process, the air passes through the shell

The long and thin drainage tube or the long and thin water outlet channel is arranged, and the water is slowly released under the action of liquid tension, so that the time delay effect is realized.

Further, when the lavatory basin goes out water for horizontal play, when no water got into in the casing, the toilet cleaning articles for use were located the bottom in the casing under the dead weight effect, and water is guided the upward motion to one side by the drainage, and leading-in from the upper portion of casing mixes with the toilet cleaning articles for use of bottom in the casing, dissolves or dilutes toilet cleaning articles for use, flows out from the casing after forming initial solution.

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, adopt the ascending drainage mode of slant, the rivers that transversely wash out are in the situation gets into the casing, and along with the volume increase that water got into the casing, the abundant of casing internal water, toilet articles for use or suspension are in the casing, or continue to be located the casing bottom, dissolve or dilute toilet articles for use, and the final initial solution that all can form flows out from the casing.

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 shell reaches the maximum and the time when the initial solution is released.

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 solution is released once in the housing.

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

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

Further, the toilet cleaning product itself or an effective bleaching component released by the toilet cleaning product after dissolution in water comprises a chemical having the structural formula (1):

wherein: r1 and R2 are independently selected from any one of C1-C6 alkyl substituents and hydrogen, and at least one of R1 and R2 is C1-C6 alkyl; x and Y are independently selected from any one of bromine, chlorine and hydrogen, and at least one of X and Y is a halogen element.

Further, the chemical substances of the toilet cleaning product or the effective bleaching components released by the toilet cleaning product after dissolving in water are selected from the following: any one of 1, 3-dichloro-5, 5-dimethylhydantoin, 1, 3-dibromo-5, 5-dimethylhydantoin, 1-bromo-3-chloro-5, 5-dimethylhydantoin, 1-chloro-3-bromo-5, 5-dimethylhydantoin, 1, 3-dichloro-5-methyl-5-ethylhydantoin, 1, 3-dibromo-5-methyl-5-ethylhydantoin, 1-bromo-3-chloro-5-methyl-5-ethylhydantoin, 1-chloro-3-bromo-5-methyl-5-ethylhydantoin, 1, 3-dibromo-5-methyl-5-isobutylhydantoin, 1, 3-dibromo-5-methyl-5-propylhydantoin, or a mixture of two or more thereof.

Further, the toilet cleaning product itself or an effective bleaching component released by the toilet cleaning product after dissolution in water comprises a chemical having the structural formula (2):

wherein: r1 and R2 are independently selected from C1-C2 alkyl substituents, X and Y are independently selected from any one of bromine, chlorine and hydrogen, and at least one of X and Y is halogen element.

Further, the chemical substances of the toilet cleaning product or the effective bleaching components released by the toilet cleaning product after dissolving in water are selected from the following: any one or two or a mixture of more than two of 1, 3-dichloro-5, 5-dimethylhydantoin, 1, 3-dibromo-5, 5-dimethylhydantoin, 1-bromo-3-bromo-5, 5-dimethylhydantoin, 1, 3-dichloro-5-methyl-5-ethylhydantoin, 1, 3-dibromo-5-methyl-5-ethylhydantoin, 1-bromo-3-chloro-5-methyl-5-ethylhydantoin, 1-chloro-3-bromo-5-methyl-5-ethylhydantoin.

In addition, in order to reduce the number of components, a rotation shaft groove may be provided on the outer sides of the locking portion 161 and the insertion portion 162, and the hook 200 may be coupled to the housing 100 through a rotation shaft.

After the left side casing 110 and the lock of right side casing 120, through a plurality of protruding position piece 181 and protruding position strip 182 that set up, be used for guaranteeing radial clearance and the axial clearance between left side casing 110 and the right side casing 120, make the casing 100 that the lock formed have certain clearance, from the angle of manufacturing, protruding position piece 181 and protruding position strip 182 all can be integrated into one piece when casting mould to left side casing 110 right side casing 120, control the size in clearance through the height that sets up protruding position piece 181 and protruding position strip 182 in advance, reduce spare part quantity, improve the manufacturing accuracy, the time of the effective solution delay release of control that can be indirect accurate. Since the size of the housing 100 itself should not be too large, and the size of the raised ring and the recessed ring is necessarily smaller, the height t of the raised block 181 and the raised strip 182 is controlled to be 0.1-0.5 mm, and preferably, t is 0.1 or 0.2 or 0.3 or 0.4 or 0.5 mm.

As shown in fig. 4, the case 100 formed by fastening the left side case 110 and the right side case 120 is a blister-shaped case having a large middle and small ends. When the left side shell 110 and the right side shell 120 are cast, the structure with the large middle and the small two ends is easy to demould, on the other hand, the structure with the large middle and the small two ends enables the integral shape of the shell 100 to be small in volume but large in volume, preferably, the left side shell 110 and the right side shell 120 are arranged to be basically symmetrical, the convex belly position of the water bubble-shaped shell is located between 1/3-2/3 of the height from bottom to top of the shell 100, namely H1-H2/H is 1/3-2/3, after the shell 100 contains toilet cleaning products and water enters, the center of gravity is located at the lower part of the shell 100, when the hook 200 is adopted to hang the shell 100 on the inner edge of a toilet bowl, the hanging is more stable and is not easy to swing, and the water can conveniently enter the cavity from the water inlet 130.

A left extending plate 111 is arranged on one side of the left shell 110 facing the water inlet 130, and a right extending plate 121 is arranged on one side of the right shell 120 facing the water inlet 130; after the left casing 110 and the right casing 120 are fastened, the left extending plate 111 and the right extending plate 121 together form the air deflector 190.

The left and

right extension plates

111 and 121 form an inverted q-shaped profile of the lateral cross-section of the left and

right housings

110 and 120, and the left and

right extension plates

111 and 121 are formed by extending the left and

right housings

110 and 120 and are integrally molded when the left and

right housings

110 and 120 are molded. Because the water of closestool lavatory basin flows from lavatory basin upper portion inner wall, for guaranteeing that water can get into water inlet 130 smoothly, set up left side extension board 111, right side extension board 121, and with left side extension board 111, right side extension board 121 sets up to the cambered surface, make guide plate 190 that left side casing 110 and right side casing 120 lock formed after be a complete mild cambered surface of controlling, make it can laminate the closestool basin inner wall, reduce the clearance between casing 100 and the closestool lavatory basin inner wall, guarantee as much as possible rivers along guide plate 190 get into in the water inlet 130.

As shown in fig. 4, because the flush volume of the toilets of different models is different, in order to control the total water volume entering the casing 100, the side of the left casing 110 and the side of the right casing 120 are all provided with small holes 150, the highest liquid level of the water entering the casing 100 is controlled, when the casing 100 is combined with the shape to ensure the use of the toilets of different models, the initial total water volume entering and remaining in the casing 100 is certain, the deviation is reduced, thereby ensuring that the concentration of the effective solution formed after the toilet cleaning product is dissolved keeps consistent, ensuring that the using effect of the effective solution after the toilet bowl is dropped into is consistent, and ensuring that the service life of the toilet cleaning product keeps consistent between the toilets of different models.

Preferably, the small holes 150 are arc-shaped holes which are concave downwards, and the positions of the small holes 150 are required to ensure that the initial volume of water entering the housing 100 is 10-50 ml. Preferably, the arc-shaped holes are obliquely arranged, and one side facing the flow guide plate 190 is a higher end, so that when the present invention is used for toilets of different models, after the upper edge of the flow guide plate 190 is attached to the inner wall of the toilet bowl of the toilet, the casing 100 is deflected along the upper edge of the flow guide plate 190 and toward the side far from the flow guide plate 190, and at this time, the lowest point position of the obliquely arranged arc-shaped holes is not greatly deviated, so that the initial total water amount entering and remaining in the casing 100 tends to be consistent.

The container provided by the embodiment is suitable for solid toilet cleaning articles, such as a solid block containing a toilet cleaning effective substance, or a water-permeable packaging bag filled with solid particles of the toilet cleaning effective substance, and is placed in the casing 100, and then the casing 100 is placed on the inner side of a toilet bowl in a fitting manner, and can be adhered to the inner side of the toilet bowl by using an adhesive, or the casing 100 is hung on the inner edge of the toilet bowl through the hook 200. When a user presses the toilet to flush, water in the toilet tank enters the water inlet 130 of the housing 100 from the inner edge of the toilet bowl. When water enters the cavity, the solid toilet cleaning effective substance in the cavity is dissolved to form effective solution, and the effective solution slowly drops into the toilet bowl from the position where the gap is left after the left shell 110 and the right shell 120 are buckled. In the process, as the effective solution is liquid and has certain tension, the tension and the liquid pressure have a mutual relation, when the liquid level is gradually reduced, the dropping speed of the solution is also gradually reduced, and the concentration of the solution is continuously increased, which is the advantage of delayed release. Because casing 100 is formed by left side casing 110 and right side casing 120 lock, the size in accessible control lock back clearance to the effective solution of control is from forming to the time that drips, has also prolonged the cycle of release promptly, makes solution most stop in the closestool, guarantees the effective material content of the toilet cleaner in the lavatory basin, has reduced the waste, has promoted practical function.

Through the size in clearance behind control left side casing and the right side casing lock to the effective solution of control is from forming to the time that drips, has also prolonged the cycle of release promptly, makes most stops in the closestool of solution, guarantees the effective material content of the toilet cleaning articles for use in the lavatory basin, has reduced the waste, has promoted practical function.

The method for releasing the toilet cleaning product in a delayed manner provided by the embodiment comprises the following steps: the water in the toilet basin enters, the water and the toilet cleaning articles are mixed to form an initial solution, the initial solution starts to be released, the water level in the toilet basin 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 in the toilet basin is called as a primary solution. In the above method, the volume of the initial solution is not less than 10 ml; and the content of the effective components of the toilet cleaning product in the primary solution is not less than 2 ppm. Preferably, the volume of the initial solution is between 10 and 50 ml.

Preferably, the solubility of the toilet article in water at 25 ℃ in the initial solution is not more than 10 g/L; or the solubility of the toilet article in the initial solution in water at 20 ℃ is not more than 5 g/L.

In the present invention, the toilet cleaning article is a chemical substance comprising a structural formula (1):

Specifically, the chemical substances of the toilet cleaning product are selected from the following substances: any one of 1, 3-dichloro-5, 5-dimethylhydantoin, 1, 3-dibromo-5, 5-dimethylhydantoin, 1-bromo-3-chloro-5, 5-dimethylhydantoin, 1-chloro-3-bromo-5, 5-dimethylhydantoin, 1, 3-dichloro-5-methyl-5-ethylhydantoin, 1, 3-dibromo-5-methyl-5-ethylhydantoin, 1-bromo-3-chloro-5-methyl-5-ethylhydantoin, 1-chloro-3-bromo-5-methyl-5-ethylhydantoin, 1, 3-dibromo-5-methyl-5-isobutylhydantoin, 1, 3-dibromo-5-methyl-5-propylhydantoin, or a mixture of two or more thereof.

In order to verify that the toilet cleaning products of different chemical substances are selected and used together with the toilet cleaning method and the device in the invention, and finally the content of the effective substances of the toilet cleaning products in the toilet basin is the condition, the inventor tests the use conditions of five different toilet cleaning products which can release effective bleaching components after being dissolved in water. In the actual test, the test data of about 30 days is intercepted, and the test data is shown in fig. 5. The method for testing the effective chlorine content in the water body of the toilet bowl comprises the following steps: the toilet cleaning product capable of releasing the effective bleaching ingredients after being dissolved in water is placed into a packaging bag and then hung on the upper edge 510 of a toilet bowl, the packaging bag can accumulate water required by packaging design at a hanging position, the toilet cleaning product is flushed for 6 times or 10 times every day at a certain interval, the water body in the toilet bowl after being flushed for every time is used for testing the effective chlorine content in the solution, and specifically provided data is the lowest data in all data tested on the same day. The method for testing the available chlorine comprises the following steps: the available chlorine test was carried out with reference to the determination (titration method) of available chlorine in detergents in chapter 19 of GB/T13173-2008 "test methods for surfactants detergents". Because the content of the available chlorine tested by the invention is lower, the concentration, the sample weighing amount and the like of the reagent are adjusted relative to the national standard test method in order to obtain a more accurate test result.

Specifically, the concentration of sodium thiosulfate in the standard titration solution is c (Na)₂S₂O₃) 0.01 mol/L; in the testing process, the sample amount is adjusted according to the content of available chlorine in the primary solution, 60-70 g of the primary solution in the toilet bowl after flushing each time is weighed by an analytical balance for testing use, and the mass m (accurate to 0.001g) is recorded; in the calculation of the result, the content of available chlorine is calculated by mass fraction X, and the numerical value is expressed by ppm, and the specific calculation process is as follows:

in the formula:

c-concentration of sodium thiosulfate standard titration solution in moles per liter (mol/L);

v-volume of sodium thiosulfate standard titration solution consumed by titration in milliliters (mL);

35.45-relative atomic mass of chlorine in grams per mole (g/mol);

m-the mass of the primary test solution weighed in grams (g).

The arithmetic mean of the two replicates is expressed to the one decimal place as the measurement result.

It should be noted that the effective chlorine content in the present application does not refer to pure effective chlorine content, and when the sample contains effective bromine, the effective bromine content is also included, and since it is difficult to distinguish the specific ratio of effective chlorine to effective bromine by using the determination method in the present experiment, for convenience of calculation, the experimental data provided in fig. 5 shows that the effective chlorine content in the water body of the toilet bowl is calculated by uniformly using the molar mass of chlorine element. From the experimental data of fig. 5, we can find that, on the basis that the content of available chlorine is not lower than 2ppm, by adopting the delayed release method of the toilet cleaning product provided by the invention, the toilet cleaning product can be flushed for 6 times every day, and the effective substances of the toilet cleaning product can be continuously released in the toilet bowl for at least more than 26 days.

In addition, as shown in fig. 6, the present embodiment also provides the solubility of the toilet articles in the initial solution, wherein the query result of the scinder Academic american chemical abstracts library is calculated by using Advanced chemical Development (ACD/Labs) Software V11.02, and from the result of the solubility data, it can be seen that the solubility of the toilet articles adopted in the present technical solution satisfies that the solubility in water at 25 ℃ is not more than 10 g/L; or has a solubility in water of not more than 5g/L at 20 ℃.

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 toilet articles for use 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 water closet adopting the structure is adopted, the water energy is required to be mixed with the toilet cleaning articles, the toilet cleaning articles can be in a solid form or granular form, and are packaged through water-permeable bags, such as non-woven fabric bags and the like. When water is mixed with the toilet cleaning product, an initial solution can be formed, along with the lengthening of the mixing time, the content of effective solute of the toilet cleaning product in the initial solution is higher and higher, and the content of solute in the initial solution released later is higher and higher; secondly, when the toilet cleaning product 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 cleaning product can be controlled to realize the purpose.

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 cleaning articles 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 released is the delayed release time of the toilet cleaning article. By controlling the dissolving speed of the toilet cleaning product, the time required for dissolving the toilet cleaning product is properly prolonged, so that the dissolving quality of the toilet cleaning product which is dissolved at the initial stage of flushing and is directly flushed away is reduced; and under the certain condition of initial solution volume, time delay release for the volume of the cleaning toilet articles for use solute in 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.

In the method, the time for mixing water and the toilet cleaning product to form an 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 articles are arranged in a container with a fixed volume, the water enters the container to start dissolving the toilet articles and release the initial solution, and the water is completely dissolved after the water is released. When the water forms an initial solution with the toilet cleaning product and is immediately released, t2 is t 3.

In the method, the water level in the toilet bowl is defined to be recovered to the normal state from the beginning of water entering the toilet bowl as the flushing time t1 of the toilet; defining the delayed release time t4 of the initial solution part from the water level in the toilet bowl returning to the normal state to the end of the initial solution release; then t 4-t 3-t 1. In the in-service use process, the toilet cleaning articles 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 cleaning articles 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 cleaning articles in the lavatory basin stop in the closestool, and the waste is reduced.

Defining the delayed release time t4 of the initial solution part from the water level in the toilet bowl to the normal state to the initial solution release end, then 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 cleaning articles are mixed to form initial solution and begin to release, therefore, the time period from the initial solution beginning release time to the initial time 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 cleaning articles, 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 the primary solution, and the solute of the toilet cleaning articles can stay in the toilet bowl as much as possible.

Defining the time from the beginning to the end of the release of the initial solution as the outflow time t3 of the initial solution, 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 two continuous uses of the closestool, the fact that the solute contained in the solution entering the closestool basin at each time is sufficient is guaranteed, and the use effect of the toilet cleaning article 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 cleaning product, 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 cleaning product stays in the toilet bowl as much as possible.

Preferably, 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 cleaning products 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 shells (a and b) are respectively mounted at the same positions of two toilets, and the shell at the position can receive water flowing into a toilet bowl from a toilet water tank; respectively putting the same solid toilet cleaning articles with the same mass and containing the cleaning component M into the shell a and the shell b; when the initial solution is released from the casing a mounted on the toilet bowl a by pressing a flush button of the toilet bowl a, the initial solution released from the casing a is completely received by the container, and the mass M of the initial solution received by the container is measured and recorded as M0. When the shell 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 corresponding volumes can be obtained by obtaining the initial solution and the primary solution with certain volumes and adopting physical and chemical methods such as drying and the like, and the actual ratio of m1 to m0 can be obtained by calculating the solute content of the initial solution and the primary solution with the whole volumes, so that the mixing ratio of the toilet cleaning product and the water and the release amount of the initial solution can be adjusted. Further, the toilet cleaning product 300 is placed in the housing 100, and water is introduced into the housing 100 to be mixed with the toilet cleaning product 300 to form an initial solution according to the structural characteristics of the toilet bowl.

As shown in fig. 7, when the water discharged from the toilet bowl 500 is discharged vertically, and no water enters the casing 100, the toilet cleaning article 300 is located at the bottom of the casing 100 under the action of its own weight, as shown by the arrow in the figure, the water is guided to move downward in an inclined manner, and is guided in from the upper part of the casing 100 to dissolve or dilute the toilet cleaning article 300, and as the amount of the water entering the casing 100 increases, the water in the casing 100 is full, and the toilet cleaning article 300 is suspended in the casing 100 or continuously located at the bottom of the casing 100, and finally, the initial solution is formed and then flows out from the water discharge hole at the bottom of the casing 100.

When the lavatory pan 500 goes out water for vertical play, the water that gets into lavatory pan 500 from the toilet bowl water tank promptly flows in along lavatory pan 500 inner wall downwards, because the rivers flow downwards along the inner wall, consequently, set up the water inlet of casing 100 on the upper portion, and towards lavatory pan 500 inner wall, in getting into leaning on casing 100 on the inner wall with rivers drainage downwards from the inner wall, mix with the toilet cleaning articles for use 300 of bottom in the casing 100, dissolve or dilute toilet cleaning articles for use 300, flow out from casing 100 bottom after forming initial solution. In the process, a long and thin drainage tube is arranged at the bottom of the shell 100 or a long and thin water outlet channel is arranged at the bottom of the shell, 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. 9, the concentration or solute content of the initial solution is gradually increased between the time when the volume of the initial solution in the housing reaches the maximum and the time when the initial solution is released. Alternatively, the concentration or solute content of the primary solution is gradually increased within the housing from the time when the volume of the primary solution reaches the maximum to the time when the release of the primary solution ends.

When water in the flush toilet just enters the shell, the toilet cleaning article is solid and is placed at the bottom of the shell, a certain weight exists, when the buoyancy generated by the amount of water entering the shell is smaller than the self gravity of the toilet cleaning article, the toilet cleaning article blocks the outlet of the shell, the toilet cleaning article is gradually dissolved in the period of time, and the concentration of the initial solution in the shell is continuously increased; when the buoyancy generated by the water quantity entering the shell is larger than the self gravity of the toilet cleaning product, the toilet cleaning product begins to leave the bottom outlet, but the water in the shell is continuously injected, and the concentration of the initial solution liquid in the shell is continuously reduced in the stage; finally, when no water enters the shell, 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 shell, at the moment, the toilet cleaning article is continuously dissolved in the water in the shell, at the moment, the concentration of the initial solution flowing out from the lower part of the shell begins to rise, and therefore the concentration of the initial solution in the shell is changed into the concentration which rises firstly, then falls and rises. In the actual experiment process, the toilet cleaning article is placed in the shell, a proper amount of liquid flowing out of the shell is collected at intervals, and the effective content of the toilet cleaning article is measured.

In this embodiment, as shown by the dark line of diamond in fig. 10, two 4g samples of the toilet cleaning product shown in fig. 5 are respectively weighed into the water-permeable packaging bags, the packaging bag samples are respectively placed into the casing 100 of the mold 1 after sealing, the volume of the casing 100 is 20mL, the drainage time interval of the casing is measured to be 5.5min, 20mL of tap water is added into the casing 100, timing is immediately performed, and a proper amount of liquid discharged from the casing 100 is collected at certain time intervals to test the solute content in the toilet cleaning product, and the obtained results are as follows:

drainage time/min	Effective chlorine concentration/ppm of discharged water sample
		0	520
0.5	542
		1	623
1.5	561
		2	520

In this embodiment, another set of experiments is performed, as shown by the gray line in the square in fig. 10, respectively weighing two 4g samples of the toilet cleaning product in fig. 5 into the water-permeable packaging bags, respectively placing the packaging bags into the housing 100 of the mold 2 after sealing, measuring the volume of the housing 100 to be 20mL, measuring the drainage time interval of the housing to be 10.5min, immediately timing after adding 20mL of tap water into the housing 100, and collecting a proper amount of liquid discharged from the housing 100 at certain time intervals to test the solute content in the toilet cleaning product, wherein the following results are obtained:

Example 2

This embodiment differs from embodiment 1 only in that: the effective bleaching component released by the toilet cleaning product after being dissolved in water comprises a chemical substance with a structural formula (2):

The chemical substances of the effective bleaching components released by the toilet cleaning product after being dissolved in water are selected from the following: any one or two or a mixture of more than two of 1, 3-dichloro-5, 5-dimethylhydantoin, 1, 3-dibromo-5, 5-dimethylhydantoin, 1-bromo-3-bromo-5, 5-dimethylhydantoin, 1, 3-dichloro-5-methyl-5-ethylhydantoin, 1, 3-dibromo-5-methyl-5-ethylhydantoin, 1-bromo-3-chloro-5-methyl-5-ethylhydantoin, 1-chloro-3-bromo-5-methyl-5-ethylhydantoin.

As shown in fig. 8, when the water discharged from the toilet bowl 500 is discharged in a horizontal direction and no water enters the housing 100, the toilet cleaning article 300 is positioned at the bottom of the housing 100 under the action of its own weight, the housing 100 is hung on the toilet bowl 500 by the hook 200, and as shown by the arrow in the figure, the water is guided to move obliquely upward, is guided from the upper part of the housing 100, is mixed with the toilet cleaning article 300 at the bottom of the housing 100, dissolves or dilutes the toilet cleaning article 300, and flows out from the drainage hole at the bottom of the housing 100 after forming an initial solution.

When 500 play waters in the lavatory basin, the water of toilet bowl water tank gets into lavatory basin 500 from 1~ 2 delivery ports that 500 borders horizontal arrangements of lavatory basin promptly, and water can transversely be washed out when washing by water, forms the swirl along 500 pond walls in the lavatory basin under the effect of gravity, increases the washing dynamics of rivers to 500 pond walls in lavatory basin like this. Therefore, by adopting the oblique upward drainage mode, the water flow which is transversely flushed out enters the casing 100 along the same way, and along with the increase of the amount of the water entering the casing 100, the water in the casing 100 is full, the toilet cleaning product 300 is suspended in the casing or continuously located at the bottom in the casing 100, dissolves or dilutes the toilet cleaning product 300, and finally, the initial solution is formed and flows out from the bottom of the casing 100.
