In order to solve the problems of serious waste of the cleaning agent 200 in the flush toilet and frequent or thick or thin concentration, the utility model provides a cleaning agent feeding device, which can fully utilize the fluctuation of the water level in the toilet water tank 100 as the source of the power of the device by additionally arranging the combination of two one-way valves on an independent accommodating tank 1, drive the device to continuously run, control the corresponding liquid to flow according to a set path, ensure that the cleaning agent 200 can be quantitatively released in times, and achieve the purposes of prolonging the service time of the cleaning agent 200 and improving the release effect of the cleaning agent.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a detergent dispensing device provided in the present invention.

In one embodiment, the detergent dispensing device provided by the utility model is used for a toilet bowl, and is arranged in a water tank 100 of the toilet bowl, as shown in fig. 1, and comprises a containing tank 1, a water inlet valve 2 and a liquid outlet valve 3. The liquid inlet or the liquid outlet of the containing box is controlled by utilizing the water level difference generated when the water level in the water tank 100 changes, and the containing box automatically operates without external power.

Wherein the receiving box 1 has a receiving cavity for receiving the detergent 200. It can be understood that the containing box 1 is a containing cavity which is the main structure of the device, and the volume of the containing box 1 is about 300 cubic centimeters and about 500 cubic centimeters. The receiving box 1 is used to receive the detergent 200 and provide an independent space for the detergent 200, allows the detergent 200 to be dissolved therein without being affected by the outside, and can serve as a storage space for a high concentration solution and peeled off debris of the detergent 200.

The water inlet valve 2 is arranged on the wall of the accommodating box 1, and the water inlet valve 2 is communicated in one direction from the water tank 100 to the accommodating cavity. The inlet valve 2 is a one-way valve for controlling water in the toilet tank 100 to flow into the accommodating tank 1 in one way, and the action and state of the inlet valve 2 are controlled by the pressure difference between the internal liquid and the external liquid at the inlet valve 2. Specifically, when the liquid level of the liquid outside the accommodating tank 1 is higher than the liquid level of the liquid inside the accommodating tank 1, the pressure difference between the outside and the inside is present at the water inlet valve 2, and the water inlet valve 2 is opened by the corresponding force, at this time, the water in the toilet tank 100 outside the accommodating tank 1 flows into the accommodating tank 1. When the liquid level of the liquid outside the accommodating box 1 changes to be equal to or less than the liquid level of the liquid inside the accommodating box 1, the pressure difference appearing at the water inlet valve 2 disappears or changes to be the pressure difference with the outside smaller than the inside, in the process, the water inlet valve 2 is not stressed or automatically resets and closes due to the opposite stress direction, and the water flow stops.

The liquid outlet valve 3 is arranged on the wall of the accommodating box 1, and the liquid outlet valve 3 is in one-way conduction from the accommodating cavity to the water tank 100. The outlet valve 3 is also a check valve, and functions to control the high concentration solution dissolved by the detergent 200 in the container 1 to be released into the toilet tank 100 in a predetermined amount. The action and the state of the liquid outlet valve 3 are controlled by the pressure difference of the liquid inside and outside the containing box 1 at the liquid outlet valve 3. Specifically, when the liquid level of the liquid in the accommodating box 1 is higher than the liquid level of the liquid outside the accommodating box 1, the liquid outlet valve 3 will present a pressure difference between the inside and the outside, and the liquid outlet valve 3 is opened by the corresponding force, so that the high concentration solution in the accommodating box 1 flows out and is released into the toilet tank 100. When the liquid level in the accommodating box 1 changes to be equal to or less than the height of the external liquid level, the pressure difference at the liquid outlet valve 3 disappears or becomes inner and outer, the liquid outlet valve 3 automatically resets and closes because of no stress or opposite stress direction in the process, the high-concentration solution stops flowing out, and the releasing process of the cleaning agent 200 stops. The detergent 200 is released to the water tank 100 once every time the outlet valve 3 is opened.

Preferably, the water inlet valve 2 opens at the lateral bottom of the tank wall. The water inlet valve 2 is arranged at a position, close to the bottom, of the accommodating box 1, so that water flowing into the accommodating box 1 can form water flow from bottom to top, the cleaning agent 200 precipitated at the bottom of the accommodating box 1 can be fully dissolved, a concentration gradient of a thin upper portion and a thick lower portion is prevented from being formed by a high-concentration solution in the accommodating box 1 through the disturbance effect of the water flow, and the concentration uniformity of the cleaning agent 200 is improved.

The liquid outlet valve 3 can be arranged on the lower half portion of the box wall, the opening position of the liquid outlet valve 3 is higher than the opening position of the water inlet valve 2, so that high-concentration cleaning agent 200 flowing out of the liquid outlet valve 3 is uniform liquid after water flow disturbance, and the release effect of the cleaning agent 200 is improved.

In order to increase the operability and the structural reliability and to minimize the structural complexity, the inlet valve 2 and/or the outlet valve 3 are conventional one-way valves.

In some embodiments, in order to improve the smoothness of the liquid flowing, the cleaning agent dispensing device provided by the present invention further includes an air pressure balance tube 4, wherein one end of the air pressure balance tube 4 is communicated with the accommodating cavity, and the other end thereof is extended into the water tank 100 and exposed above the liquid level of the water tank 100 with the open end thereof. In a specific use scenario, the air pressure balance tube 4 is a hollow tube with one end connected to the top of the container and the other end always above the liquid level of the toilet tank 100, and the inner diameter is about 1 mm. The air pressure balance tube 4 can balance the air pressure inside and outside the container when the liquid flows out and flows into the container, thereby improving the smoothness of the liquid flow.

In order to separate the broken solid detergent 200 from the dissolved detergent 200 and ensure that the detergent 200 discharged through the liquid outlet valve 3 is a liquid with a proper concentration, thereby preventing the solid detergent 200 from running off, the device further comprises a partition plate 5, wherein the partition plate 5 is arranged in the accommodating cavity and divides the accommodating cavity into a first cavity and a second cavity, and the first cavity and the second cavity are communicated through a liquid channel. The liquid and the solid in the accommodating cavity can be separated through the partition plate 5, so that the loss of the solid cleaning agent 200 can be avoided, the solid in the accommodating cavity can be prevented from blocking the channels of the water inlet valve 2 and the liquid outlet valve 3, and the influence on the normal operation of the water inlet valve 2 and the liquid outlet valve 3 is avoided.

It should be understood that the liquid passage is a passage capable of blocking solids and allowing liquid to pass, for example, the partition 5 is a screen having a predetermined number of filtering meshes, and the filtering holes of the screen form the liquid passage.

The working process of the detergent dispensing device provided by the utility model is briefly described as follows by taking the above specific embodiment as an example:

first, a detergent dispenser containing a detergent 200 is put into the toilet tank 100, and the device is gradually sunk into the bottom of the toilet tank 100 by its own weight. As shown in fig. 2, in the process of gradually sinking the device, the liquid level outside the containing box 1 is higher than the liquid level inside the containing box 1, at this time, the water inlet valve 2 is opened by the action of the pushing force from outside to inside, meanwhile, the liquid outlet valve 3 is also stressed from outside to inside in the process, and the stress direction is opposite to the conduction direction of the liquid outlet valve 3, so that the liquid outlet valve 3 is always in the closed state, and the water in the water tank 100 can only gradually enter the containing box 1 through the water inlet valve 2 until the water level inside the containing box 1 is equal to the water level outside the containing box 1. At this time, as shown in fig. 3, the water inlet valve 2 is forced to disappear and is reset to be closed, and the device finishes the water inlet process. Then the water inlet valve 2 and the liquid outlet valve 3 of the device are both in a closed state, the accommodating box 1 is in an internal and external isolation state, and the cleaning agent 200 in the accommodating box begins to dissolve when meeting water.

When the toilet is flushed, as shown in fig. 4, the water level in the water tank 100 begins to drop, the liquid level in the containing tank 1 becomes higher than the liquid level outside the containing tank 1, at this time, the liquid outlet valve 3 is opened by the force, the high-concentration solution in the containing tank 1 flows out from the liquid outlet valve 3, that is, the detergent 200 begins to be released into the water tank 100, the liquid level in the containing tank 1 also drops, and in this process, the water inlet valve 2 is forced, but the direction of the force is opposite, and the water inlet valve continues to be in the closed state.

After the toilet is flushed, as shown in fig. 5, the water level in the water tank 100 begins to rise, and when the water level rises to the same level inside and outside the accommodating tank 1, the force applied to the liquid outlet valve 3 disappears, so that the liquid outlet valve 3 is reset and closed, the high-concentration solution stops flowing out, and the device finishes a release action of the cleaning agent 200. When the water level in the water tank 100 continues to rise, so that the liquid level outside the accommodating tank 1 is higher than the liquid level inside the accommodating tank 1, as shown in fig. 6, at this time, the water inlet valve 2 is forced to open, the water in the water tank 100 (for convenience of explanation, from this point, the low-concentration detergent 200 solution in the water tank 100 is expressed as water) starts to gradually enter the accommodating tank 1, so that the liquid level inside the accommodating tank 1 gradually rises, until the liquid levels inside and outside the accommodating tank 1 are equal, the force applied to the water inlet valve 2 disappears, the water inlet valve 2 is reset to close (as shown in fig. 3), and the device finishes one action of replenishing water into the accommodating tank 1.

Thereafter, the accommodating box 1 is in a state of being separated from the inside and the outside, and the detergent 200 is continuously dissolved in the accommodating box 1 until the next toilet flushing. The device repeats the above-mentioned action every time the toilet is flushed.

It should be noted that during the course of action, the device includes several main state processes:

in the static state as shown in fig. 3, the toilet is flushed, the water level of the water tank 100 is lowered, the liquid outlet valve 3 is opened, the high-concentration solution in the accommodating tank 1 is discharged, and the liquid level in the accommodating tank 1 is lowered (as shown in fig. 4);

as shown in fig. 5, when the toilet is flushed, the water level of the water tank 100 rises, the liquid outlet valve 3 is closed, the release of the primary cleaning agent 200 is completed, then the water inlet valve 2 is opened to replenish water into the accommodating tank 1 (shown in fig. 6), the liquid level in the accommodating tank 1 rises, the water inlet valve 2 is closed, the accommodating tank 1 completes the primary water replenishing (returns to the state shown in fig. 3), and then the device is in a static state to wait for the next flushing of the toilet. The toilet is flushed again and the tank 100 level drops … …, and the process repeats. In the above process, the detergent 200 is dissolved in the container 1 until the detergent 200 discharged from the liquid outlet valve 3 becomes gradually diluted after the detergent is continuously discharged and becomes low in concentration, which indicates that the device has completed a usage cycle.

Accordingly, in the above embodiment, the detergent dispensing device provided by the present invention, through the arrangement of the accommodating box 1, the detergent 200 can be dissolved in a space independent from the water tank 100, and after being sufficiently dissolved, the detergent 200 solution is released into the toilet water tank 100 in a quantitative manner, so that the dissolving process and the releasing process of the detergent 200 are respectively performed. Thus, the detergent 200 is dissolved in a separate space, although the dissolving process is not changed, the high-concentration solution with the excessively high concentration dissolved by the detergent 200 and the peeled fragments are still remained in the space and are not released into the water tank 100 of the toilet, so that the high-concentration solution and the peeled fragments are not directly washed away by the water in the water tank 100 of the toilet, and the fragments remained in the accommodating tank 1 are further dissolved, so that the detergent 200 can be fully utilized, and the problem that the detergent 200 is wasted in the using process is solved; meanwhile, the device can release the high-concentration solution dissolved by the cleaning agent 200 into the toilet water tank 100 in a quantitative manner, so that the problem of waste caused by direct release of the high-concentration solution is solved, the cleaning agent 200 solution diluted for the second time in the toilet water tank 100 can be kept at a proper concentration all the time, the problems that the concentration of the solution fluctuates greatly and the wall is easy to remain on the wall are solved, and the release effect of the cleaning agent 200 is improved.

The detergent feeding device can achieve the purposes of prolonging the service time of the detergent 200 and improving the use experience of a user. It is verified that under the same other conditions, after the detergent feeding device is applied, the service time of the detergent 200 is more than twice of the original service time, the other problems are effectively solved, and the effects of saving resources and protecting the environment are achieved.

Furthermore, the application of the detergent feeding device can embody the advantage of high cleaning performance density ratio of the solid detergent 200, can use a smaller amount of the detergent 200 for a longer time, and can retain the advantages of convenient storage and transportation of the detergent 200 due to the solid state of the detergent 200 compared with the liquid detergent 200. Advantageously, if the formulation of the cleaning agent 200 is optimally adjusted in combination with the characteristics of the apparatus, a product of the cleaning agent 200 with better use effect and better user experience can be produced. For example, products with an excessively long service time can be produced, new detergent 200 products with increased contents that have been inconvenient to add due to dissolution problems in the past can be produced, and the like. The application of the device allows for greater flexibility in the combination and adjustment of the components of the cleaner 200 formulation.

The detergent dispenser can be applied to various detergents 200 with different formulations, and since the working process is only mechanical action, the detergent dispenser only optimizes the dissolution space of the detergent 200 and improves the release mode of the detergent 200, so that various cleaning characteristics and effects of the detergent 200 themselves are not changed.

The detergent dispenser has a function of storing a high concentration solution, and thus can be applied to the liquid detergent 200, so that the liquid detergent can be discharged into the toilet tank 100 in a predetermined amount.

In addition to the detergent dispensing device, the present invention also provides a toilet bowl including the detergent dispensing device, and other structures of the toilet bowl are referred to the prior art and are not described herein again.
