Description

Technical Field

[0001] The present invention belongs to the field of toilet supplies, and particularly relates to a slow-release cleaning device for a toilet water tank. Background Art

[0002] A flush toilet includes a water tank and a toilet main body. After use, the toilet main body will generate stains and emit odors, and manual cleaning is rather troublesome. For this reason, corresponding cleaning devices for water tanks have emerged on the market.

[0003] For example, in the utility model patent with the application number 2016211123762, a slow-release device for toilet tank cleaner is mentioned. It includes a housing and a cover installed at the upper end of the housing. The housing is provided with a receiving cavity for loading the cleaner, and the side wall of the receiving cavity is provided with liquid exchange holes. The cover is provided with air circulation holes for maintaining air pressure balance. During the process of draining and filling water in the water tank, the water body can normally enter and exit the receiving cavity through the liquid exchange holes to contact the cleaner to form a mixed liquid and bring the mixed liquid into the water tank. When the water tank drains, the mixed liquid can be discharged together to flush the toilet main body, which is relatively convenient to use. However, since the air circulation holes of this device are always kept open, the mixed liquid in the receiving cavity will be discharged and diffused into the water tank through the air pressure holes, resulting in the problems of too fast dissolution and excessive release of the cleaner.

[0004] To solve this problem, the applicant proposed a cleaning device for a toilet water tank in the utility model patent with the application number 2024204901805. By setting a second buoyancy plug at the air pressure holes (air circulation holes) to cut off the flow channel of the mixed liquid, it is ensured that the mixed liquid can only be released through the diversion holes (liquid exchange holes), thereby delaying the release of the cleaner and ensuring that the cleaner can be used for a longer time. However, it is found during use that when the water body in the water tank submerges the diversion holes, the cleaner still dissolves and releases continuously, and the actual slow-release effect is still not ideal enough, with relatively large defects. Therefore, it is urgently necessary to design a new device to solve this problem. Summary of the Invention

DETAILED DESCRIPTION

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention. It can be understood that the accompanying drawings are only for reference and illustration, and are not used to limit the present invention. The connection relationships shown in the drawings are only for clear description and do not limit the connection methods.

[0024] Embodiment 1 Refer to the attached Figure 1 - attached Figure 9 , a slow-release cleaning device for a toilet water tank, including a first buoyancy plug 1, a second buoyancy plug 2 and a bottle body 3; a receiving cavity 30 for placing a cleaning agent is provided inside the bottle body 3, and a diversion hole 301 and a pressure hole 302 communicating with the outside are provided on the side wall of the receiving cavity 30, and the pressure hole 302 is located above the diversion hole 301; the first buoyancy plug 1 is movably installed at the diversion hole 301, and the first buoyancy plug 1 can float with the water level in the water tank to open or close the diversion hole 301; the second buoyancy plug 2 is movably installed at the pressure hole 302, and the second buoyancy plug 2 can float with the water level in the water tank to open or close the pressure hole 302; wherein, a water cut-off level and a water passing interval are formed from top to bottom between the diversion hole 301 and the pressure hole 302, and the position of the water cut-off level is not lower than the pressure hole 302.

[0025] Specifically, when the bottle body 3, the first buoyancy plug 1 and the second buoyancy plug 2 are completely immersed in the water body of the water tank (not shown in the figure), the first buoyancy plug 1 and the second buoyancy plug 2 float up and close the diversion hole 301 and the pressure hole 302 respectively, so as to completely cut off the water path between the bottle body 3 and the water tank and prevent the mixed liquid in the receiving cavity 30 from continuously escaping into the water tank through the diversion hole 301 and the pressure hole 302.

[0026] During the process of flushing the toilet main body (not shown in the figure), the water level in the water tank will gradually drop. When the water level in the water tank is in the water passing interval and lower than the pressure hole 302, the first buoyancy plug 1 and the second buoyancy plug 2 move down respectively and open the diversion hole 301 and the pressure hole 302 respectively. The opened pressure hole 302 can maintain the air pressure balance inside and outside the receiving cavity 30. Under the action of air pressure, the liquid level in the receiving cavity 30 needs to be consistent with the water level in the water tank. Therefore, the mixed liquid in the receiving cavity 30 will be discharged into the water tank through the diversion hole 301 as the water level in the water tank drops, so that the water body in the water tank has the effect of cleaning the toilet main body, and the discharge stops until the liquid level of the mixed liquid in the receiving cavity 30 is lower than the diversion hole 301.

[0027] During the process of the water tank refilling, the liquid level in the water tank will gradually rise. When the liquid level in the water tank enters the water passing interval, the first buoyancy plug 1 will slightly float up and not close the diversion hole 301. Since the air pressure hole 302 is in an open state, under the action of air pressure, the liquid level in the water tank will be consistent with the liquid level in the accommodation cavity 30. Therefore, the water in the water tank will continuously enter the accommodation cavity 30 through the diversion hole 301 and contact the cleaning agent to form a mixed liquid. When the liquid level in the water tank continues to rise, depending on the position of the water cut-off level, there are the following two situations: First, if the position of the water cut-off level is flush with the air pressure hole 302, then when the liquid level in the water tank continues to rise to the water cut-off level, the accommodation cavity 30 will be filled with the mixed liquid, and the first buoyancy plug 1 and the second buoyancy plug 2 will float up synchronously and close the diversion hole 301 and the air pressure hole 302 respectively, so as to prevent the mixed liquid in the accommodation cavity 30 from continuously escaping into the water tank through the diversion hole 301 and the air pressure hole 302; Second, if the position of the water cut-off level is higher than the air pressure hole 302, then when the liquid level in the water tank rises to the air pressure hole 302, the accommodation cavity 30 has been filled with the mixed liquid, and the second buoyancy plug 2 will first close the air pressure hole 302, while the diversion hole 301 is still in an open state, so that a small amount of the mixed liquid in the accommodation cavity 30 can still escape into the water tank, thereby increasing the concentration of the cleaning agent in the water inside the water tank and improving the cleaning effect of the water body; after the liquid level in the water tank continues to rise to the water cut-off level, the first buoyancy plug 1 will completely float up and close the diversion port to prevent the mixed liquid in the accommodation cavity 30 from continuing to escape into the water tank through the diversion hole 301.

[0028] In summary, the present invention designs an accommodation cavity 30 in the bottle body 3 for placing the cleaning agent, designs an air pressure hole 302 on the side wall of the accommodation cavity 30 to ensure the air pressure balance inside and outside the bottle body 3, so that the water in the water tank and the accommodation cavity 30 can flow smoothly through the diversion hole 301; designs the first buoyancy plug 1 and the second buoyancy plug 2 to open and close the diversion hole 301 and the air pressure hole 302 respectively under specific circumstances. On the one hand, during the process of the water tank refilling, the water body can be introduced into the accommodation cavity 30 to contact the cleaning agent to form a mixed liquid, and after the water tank is filled with water, the channels between the bottle body 3 and the water tank can be completely cut off to prevent the mixed liquid in the accommodation cavity 30 from being discharged into the water tank through the diversion hole 301 and the air pressure hole 302, effectively reducing the dissolution rate of the cleaning agent; on the other hand, during the process of flushing the toilet main body, the mixed liquid in the accommodation cavity 30 can be smoothly discharged into the water body in the water tank to improve the flushing and cleaning effect; Among them, the mixed liquid formed by the water body contacting the cleaning agent has a diffusion effect. Therefore, the more channels there are between the accommodating cavity 30 and the water tank, the faster the diffusion speed. On the contrary, since the diversion hole 301 and the air pressure hole 302 of this slow-release cleaning device are closed, the diffusion speed of the mixed liquid can be comprehensively delayed, avoiding liquid exchange between the accommodating cavity 30 and the water tank after the water tank is filled with water. Therefore, this slow-release cleaning device can perfectly control the release timing of the cleaning agent, further avoiding the cleaning agent from dissolving too quickly and releasing too much, enhancing the slow-release effect, ensuring that the cleaning agent can be used for a long time, and reducing the user's usage cost.

[0029] Embodiment 2 Refer to the appendix Figure 10 - Appendix Figure 16 , a slow-release cleaning device for a toilet water tank, including a bottle body 3, a first buoyancy plug 1 and a second buoyancy plug 2; an accommodating cavity 30 for placing a cleaning agent is provided inside the bottle body 3, and a diversion hole 301 and an air pressure hole 302 communicating with the outside are provided on the side wall of the accommodating cavity 30, and the air pressure hole 302 is located above the diversion hole 301; the first buoyancy plug 1 is movably installed at the diversion hole 301, and the first buoyancy plug 1 can open or close the diversion hole 301 as the water level in the water tank floats; the second buoyancy plug 2 is movably installed at the air pressure hole 302, and the second buoyancy plug 2 can open or close the air pressure hole 302 as the water level in the water tank floats; among them, a water cut-off level and a water passing interval are formed from top to bottom between the diversion hole 301 and the air pressure hole 302, and the position of the water cut-off level is lower than the air pressure hole 302.

[0030] Specifically, when the bottle body 3, the first buoyancy plug 1 and the second buoyancy plug 2 are completely immersed in the water body of the water tank (not shown in the figure), the first buoyancy plug 1 and the second buoyancy plug 2 float up and close the diversion hole 301 and the air pressure hole 302 respectively to completely cut off the escape channel of the mixed liquid.

[0031] During the process of flushing the toilet main body (not shown in the figure), the water level in the water tank will gradually drop. When the water level in the water tank drops below the air pressure hole 302, if the water level in the water tank does not enter the water passing interval, the water body in the accommodating cavity 30 remains full, resulting in the second buoyancy plug 2 being unable to open the air pressure hole 302; when and only when the water level in the water tank drops below the water cut-off level and enters the water passing interval, the first buoyancy plug 1 opens the diversion hole 301, so that the mixed liquid in the accommodating cavity 30 has a flowing tendency, and the second buoyancy plug 2 can open the air pressure hole 302 to maintain the air pressure balance inside and outside the accommodating cavity 30. And under the action of air pressure, the water level heights of the accommodating cavity 30 and the water tank will be kept the same. Therefore, the mixed liquid in the accommodating cavity 30 will be discharged into the water tank through the diversion hole 301 as the water level in the water tank drops, making the water body in the water tank have a cleaning effect until the liquid level in the accommodating cavity 30 is lower than the diversion hole 301 and then the mixed liquid stops discharging.

[0032] During the process of the water tank refilling, when the liquid level in the water tank rises to the cut-off water level, the first buoyancy plug 1 will first close the diversion hole 301. At this time, there is air in the accommodation cavity 30 because the mixture is not fully filled, but the overall gravity of the bottle body 3 containing the cleaning agent and the mixture is greater than its own buoyancy to prevent the bottle body 3 from floating up. When the liquid level in the water tank continues to rise to the air pressure hole 302, the water in the water tank will flow into the accommodation cavity 30 through the air pressure hole 302 and discharge the air. It is not until the accommodation cavity 30 is fully filled with the mixture that the second buoyancy plug 2 completely floats up and closes the air pressure port to prevent the mixture in the accommodation cavity 30 from escaping into the water tank through the air pressure hole 302.

[0033] Among them, under normal circumstances, the accommodation cavity 30 that is not fully filled with the mixture contains air, which will increase the buoyancy of the bottle body 3, resulting in the air pressure hole 302 not being submerged by the water in the water tank. However, by increasing the weight of the bottle body 3 itself to increase the gravity it receives, it can effectively overcome the buoyancy and avoid floating, ensuring that the air pressure hole 302 of the bottle body 3 can be normally submerged by the water in the water tank.

[0034] In summary, compared with the technical solution in Embodiment 1, the technical solution described in Embodiment 2 can significantly reduce the opening time of the diversion hole 301, further reduce the release speed of the mixture, and reduce the use of the cleaning agent. However, correspondingly, it will also cause the cleaning effect of the water in the water tank to decline somewhat, and users can choose according to their own needs.

[0035] It should be noted that in actual application, the manufacturer can choose the technical solution in Embodiment 1 or Embodiment 2 to set the location of the cut-off water level according to the user's cleaning requirements for the toilet main body and the user's demand for the use duration of the cleaning agent. This invention does not limit this. In addition, there are various types of cleaning agents. For example, slow-release gels, soap-like solids, etc. can be used to effectively ensure the use time of the cleaning agent, and users can also choose cleaning agents with corresponding scents and forms according to their own preferences. This invention also does not limit this.

[0036] Among them, as shown in the appendix Figure 8 In Embodiment 1, the length of the first buoyancy plug 1 is relatively large. Therefore, when using a solid cleaning agent, holes can be dug in the solid cleaning agent to provide space for the first buoyancy plug 1 to move. If holes are not dug in the solid cleaning agent, the solid cleaning agent will support the first piston, but this will not affect the normal use of this slow-release cleaning device. The manufacturer can adjust according to the actual use effect. Similarly, in Embodiment 2, the first buoyancy plug 1 is shorter. Therefore, when using a solid cleaning agent, the manufacturer can directly support the first buoyancy plug 1 with the fixed cleaning agent without digging holes in the fixed cleaning agent to provide space for the first buoyancy plug 1 to move.

[0037] It should also be noted that in the first embodiment, the water body has a tendency to drive the bottle body 3 to float and shake. Therefore, the manufacturer can also increase the overall weight of the bottle body 3 so that the bottle body 3 can effectively overcome the buoyancy and prevent the bottle body 3 from shaking during use and affecting the liquid exchange between the accommodating cavity 30 and the water tank. Regarding the method of increasing the overall weight of the bottle body 3, the manufacturer can increase the mass of the cleaning agent, or use metal or other materials with a certain weight to make the bottle body 3, or embed a weight block (not shown in the figure) on the bottle body 3. Since there are various relevant weight-increasing methods, the present invention does not limit this either.

[0038] Refer to the attached Figure 1 - attached Figure 7 and attached Figure 10 - attached Figure 15 , the first buoyancy plug 1 includes a first floating ball 11, a first sliding column 12 and a first plug block 13; the first sliding column 12 is slidably installed in the diversion hole 301, and there is a liquid gap 120 for the water body to pass between the first sliding column 12 and the diversion hole 301; the first plug block 13 is installed at the bottom of the first sliding column 12 and placed in the accommodating cavity 30; the first floating ball 11 is installed at the top of the first sliding column 12 and placed outside, and the first floating ball 11 is made of a material with a density lower than that of the water body; wherein, when the first plug block 13 opens the diversion hole 301, the accommodating cavity 30 is connected to the outside through the liquid gap 120.

[0039] As shown in the attached Figure 1 - attached Figure 7 As shown in the figure, the working principle of this first buoyancy plug 1 structure in the first embodiment is as follows: when the water tank liquid level rises to the water passing interval, the first floating ball 11 floats synchronously and drives the first plug block 13 to gradually approach the diversion hole 301, and at this time the liquid gap 120 can allow the water body to pass normally; when the water tank liquid level rises to the water cut-off level, the first floating ball 11 continues to float and drives the first plug block 13 to close the diversion hole 301; when and only when the diversion hole 301 and the air pressure hole 302 are both opened, the mixed liquid in the accommodating cavity 30 can be discharged. Therefore, only when the water tank liquid level drops to the water passing interval and is lower than the air pressure hole 302, the second buoyancy plug 2 drops under the action of gravity to open the air pressure hole 302 to maintain the air pressure balance inside and outside the accommodating cavity 30, and the first buoyancy plug 1 drops under the action of gravity to drive the first plug block 13 to open the diversion hole 301, can the accommodating cavity 30 be connected to the outside through the liquid gap 120 to achieve liquid exchange.

[0040] As shown in the attached Figure 10 - attached Figure 15As shown in the figure, the working principle of this first buoyancy plug 1 structure in the second embodiment is as follows: when the water level in the water tank rises to the cut-off water level, the first floating ball 11 floats synchronously and drives the first plug 13 to close the diversion hole 301 first, and at this time, the accommodating cavity 30 is not filled with the mixed liquid; when the water level in the water tank continues to rise to the air pressure hole 302, the water in the water tank will flow into the accommodating cavity 30 through the air pressure hole 302 and discharge the air inside the accommodating cavity 30. After the accommodating cavity 30 is filled with the mixed liquid, the water level in the water tank rises above the air pressure hole 302, and then the second buoyancy plug 2 completely floats up to close the air pressure port to prevent the mixed liquid in the accommodating cavity 30 from escaping into the water tank through the air pressure hole 302; when the water level in the water tank drops below the air pressure hole 302 and enters the water passing interval, the second buoyancy plug 2 drops under the action of gravity to open the air pressure hole 302, and the first buoyancy plug 1 drops under the action of gravity to drive the first sliding column 12 to move downward, and the first plug 13 is made to open the diversion hole 301, and at this time, the accommodating cavity 30 can be connected to the outside through the liquid gap 120 to achieve liquid exchange.

[0041] In summary, the method of driving the first sliding column 12 and the first plug 13 to move only by the buoyancy of the first floating ball 11 enables the first buoyancy plug 1 to accurately follow the liquid level. It can not only accurately control the timing of the first plug 13 closing the diversion hole 301 during the water storage and drainage processes of the water tank, but also prevent the first plug 13 from directly closing the diversion hole 301 when the water level in the water tank is level with the diversion hole 301, or prevent the first plug 13 from being unable to close the diversion hole 301 when the water level in the water tank submerges the first floating ball 11; in addition, the overall structure of the first buoyancy plug 1 composed of the first sliding column 12, the first floating ball 11, and the first plug 13 is simple, low in cost, and it does not occupy too much internal space of the bottle body 3, enabling the bottle body 3 to vacate more space in the accommodating cavity 30 for placing the cleaning agent, thereby extending the overall service time.

[0042] Further, as shown in the attached Figure 9 figure, in another embodiment, the first floating ball 11, the first sliding column 12, and the first plug 13 are all made of materials with a density lower than that of water and are integrally formed, and the distance value between the diversion hole 301 and the air pressure hole 302 does not exceed the length value of the first sliding column 12.

[0043] Specifically, the above structural design not only facilitates the processing and production of the first buoyancy plug 1 but also enables the first buoyancy plug 1 to float by its own overall buoyancy; under this design, the water body does not need to contact the first floating ball 11, and only needs to submerge to a specific position of the first sliding column 12 to drive the first buoyancy plug 1 to float to a suitable position and drive the first plug 13 to close the diversion hole 301.

[0044] Wherein, when the distance value between the diversion hole 301 and the air pressure hole 302 is less than the length value of the first sliding column 12, the overall weight or volume of the first buoyancy plug 1 can be adjusted to ensure that the water body can drive the first plug block 13 to close the diversion hole 301 without completely submerging the first sliding column 12; when the distance value between the diversion hole 301 and the air pressure hole 302 is equal to the length value of the first sliding column 12, the overall weight or volume of the first buoyancy plug 1 can be adjusted to ensure that the water body just completely submerges the first sliding column 12 to drive the first plug block 13 to close the diversion hole 301.

[0045] In addition, the user can also change the floating state of the first buoyancy plug 1 in the water body by adjusting the overall weight or volume of the first buoyancy plug 1. For example, increasing the overall weight of the first buoyancy plug 1 will cause the first sliding column 12 to be more submerged in the water, while reducing the weight will cause the first sliding column 12 to be more exposed above the water surface; by reasonably controlling the floating state of the first buoyancy, it can prevent the first plug block 13 from directly closing the diversion hole 301 when the water level in the water tank is flush with the diversion hole 301, or prevent the first plug block 13 from being unable to close the diversion hole 301 when the water level in the water tank submerges the first floating ball 11. Refer to the appendix Figure 1 - appendix Figure 7 and appendix Figure 10 - appendix Figure 15 , the second buoyancy plug 2 includes a second floating ball 21, a second sliding column 22 and a second plug block 23; the second sliding column 22 is slidably installed in the air pressure hole 302, and there is a gas gap 220 for gas passage between the second sliding column 22 and the air pressure hole 302; the second plug block 23 is installed at the bottom of the second sliding column 22 and placed in the accommodation cavity 30; the second floating ball 21 is installed at the top of the second sliding column 22 and placed outside, and the second floating ball 21 is made of a material with a density lower than that of the water body; wherein, when the second plug block 23 opens the air pressure hole 302, the accommodation cavity 30 is connected to the outside through the gas gap 220.

[0046] As shown in the appendix Figure 1 - appendix Figure 7 As shown, the working principle of applying the above structure of the second buoyancy plug 2 in the first embodiment is: when the water level in the water tank rises to the cut-off water level or above the air pressure hole 302, the second buoyancy plug 2 floats under the buoyancy of the second floating ball 21, driving the second sliding column 22 to move upward and causing the second plug block 23 to close the air pressure hole 302; when the water level in the water tank drops below the air pressure hole 302, the second buoyancy plug 2 drops under the action of gravity, driving the second sliding column 22 to move downward and causing the second plug block 23 to open the air pressure hole 302, and at this time the accommodation cavity 30 is connected to the outside through the gas gap 220, ensuring that the first buoyancy plug 1 can be normally opened and liquid exchange can be carried out through the diversion hole 301.

[0047] As shown in the appendix Figure 10 - appendix Figure 15As shown in the figure, the working principle of the structure of the second buoyancy plug 2 applied in the second embodiment is as follows: when the water level in the water tank rises above the air pressure hole 302, the second buoyancy plug 2 floats under the buoyancy of the second floating ball 21 to drive the second plug block 23 to close the air pressure hole 302; when the water level in the water tank drops below the air pressure hole 302, the second buoyancy plug 2 drops under the action of gravity to drive the second sliding column 22 to move downward, and the second plug block 23 opens the air pressure hole 302. At this time, the accommodating cavity 30 is connected to the outside through the gas gap 220 to ensure that the first buoyancy plug 1 can be normally opened and liquid exchange can be carried out through the diversion hole 301.

[0048] In summary, the method of driving the second sliding column 22 and the second plug block 23 to move only by the buoyancy of the second floating ball 21 enables the second buoyancy plug 2 to accurately follow the liquid level movement. During the process of water storage and drainage in the water tank, the timing of the second plug block 23 closing the air pressure hole 302 can be accurately controlled. It can not only prevent the mixed liquid from escaping when the water level in the water tank submerges the second floating ball 21 and the second plug block 23 cannot close the air pressure hole 302, but also prevent the second plug block 23 from not being able to open the air pressure hole 302 in time to maintain the balance inside and outside the accommodating cavity 30 when the water level in the water tank is lower than the air pressure hole 302. In addition, the overall structure of the second buoyancy plug 2 composed of the second sliding column 22, the second floating ball 21 and the second plug block 23 is simple, with low cost, and it does not occupy too much internal space of the bottle body 3, enabling the bottle body 3 to vacate more space in the accommodating cavity 30 to place the cleaning agent, thereby extending the overall service time.

[0049] Further, as shown in the appendix Figure 16 The second floating ball 21, the second sliding column 22 and the second plug block 23 are all made of materials with a density lower than that of water and are integrally formed.

[0050] Specifically, the above structural design not only facilitates the processing and production of the second buoyancy plug 2, but also enables the second buoyancy plug 2 to float relying on its overall buoyancy. Under this design, the water body does not need to contact the second floating ball 21, and only needs to submerge to a specific position of the second sliding column 22 to drive the second buoyancy plug 2 to float to a suitable position and drive the second plug block 23 to close the diversion hole 301.

[0051] Among them, by adjusting the overall weight or volume of the second buoyancy plug 2, its floating state in the water body can be changed, so that when the water body submerges to a specific position of the second sliding column 22, the second plug block 23 closes the air pressure hole 302. Relevant cases have been mentioned above, and specifically, the structural analysis of the first buoyancy plug 1 in the above text can be referred to, and will not be repeated here.

[0052] It should be noted that there are various types of materials with a density lower than that of water and having buoyancy, such as eva materials, foam plastics, rubber materials, etc. The present invention does not limit this.

[0053] See attached Figure 4 , Attachment Figure 12 , Attachment Figure 18 and attached Figure 19 A first spacer 111 is provided on the first float 11, and the first spacer 111 can abut against the bottle body 3 as the first float 11 falls and form a first opening 1110 connected to the liquid gap 120; a second spacer 211 is provided on the second float 21, and the second spacer 211 can abut against the bottle body 3 as the second float 21 falls and form a second opening 2110 connected to the gas gap 220.

[0054] Specifically, the design of the first spacer 111 and the second spacer 211 can prevent the first float 11 and the second float 21 from closing the liquid gap 120 and the gas gap 220 respectively after they fall, ensuring that the accommodating chamber 30 can be more smoothly connected to the outside world and maintain the balance of internal and external air pressure, thereby ensuring smooth liquid exchange.

[0055] See attached Figure 18 -Attached Figure 19 The first spacer 111 is provided in a plurality and arranged in a circular array at the bottom of the first float 11, and a first opening 1110 is formed between each of the plurality of first spacer 111; the second spacer 211 is provided in a plurality and arranged in a circular array at the bottom of the second float 21, and a second opening 2110 is formed between each of the plurality of second spacer 211.

[0056] Specifically, this design enables multiple first openings 1110 to be spaced apart in the circumferential direction around the guide hole 301 and synchronously connected to the liquid gap 120, and enables multiple second openings 2110 to be spaced apart in the circumferential direction around the air pressure hole 302 and synchronously connected to the gas gap 220, thereby ensuring that the gas flow in the accommodating chamber 30 is more stable; at the same time, the design of multiple first spacers 111 and second spacers 211 can also make the contact between the first float 11 and the second float 21 and the bottle body 3 more stable.

[0057] For ease of understanding, in the present invention, a plurality of first spacers 111 and a plurality of second spacers 211 are taken as an example in which the cross-shaped design is adopted, wherein the four first openings 1110 formed by the cross-shaped first spacer 111 are of the same size, and the four second openings 2110 formed by the cross-shaped second spacer 211 are of the same size, which can ensure stable ventilation of the accommodating cavity 30, and at the same time provide the same support at each location on the bottom side of the first float 11 and the second float 21 respectively, so that the first float 11 and the second float 21 are subjected to balanced forces, effectively preventing the first float 11 and the second float 21 from offsetting and blocking the liquid gap 120 and the gas gap 220.

[0058] Further, the contact surface between the bottle body 3 and the partition block can be an arc surface, a flat surface, etc. In order to make the first partition block 111 and the second partition block 211 be placed on the bottle body 3 more stably, in the present invention, the contact surface between the bottle body 3 and the first partition block 111 and the second partition block 211 preferably adopts a flat surface.

[0059] Refer to the appendix Figure 4 , appendix Figure 12 , appendix Figure 18 and appendix Figure 19 , the first plug 13 and the second plug 23 are both hemispherical, and the diameter of the first plug 13 is greater than the diameter of the diversion hole 301, and the diameter of the second plug 23 is greater than the diameter of the air pressure hole 302.

[0060] Specifically, during actual use, the first floating ball 11 and the second floating ball 21 shift, resulting in the first sliding column 12 and the second sliding column 22 shifting in the diversion hole 301 and the air pressure hole 302 respectively; and the above design can ensure that the first plug 13 and the second plug 23 can still normally block the diversion hole 301 and the air pressure hole 302 when the first floating ball 11 and the second floating ball 21 shift, effectively avoiding the dissipation of the mixed liquid.

[0061] Refer to the appendix Figure 17 , the bottle body 3 includes a detachable bottle body 31 and a bottle cap 32, and the bottle body 31 and the bottle cap 32 enclose to form a receiving cavity 30, and the diversion hole 301 and the air pressure hole 302 are both arranged on the bottle cap 32.

[0062] Specifically, the bottle body 31 and the bottle cap 32 are detachably connected, so that the bottle body 3 can be assembled and disassembled to facilitate the cleaning of the receiving cavity 30 and the replacement of the cleaning agent; the positions of the diversion hole 301 and the air pressure hole 302 can be set according to actual needs. For example, the diversion hole 301 and the air pressure hole 302 are generally arranged on the bottle cap 32 to facilitate processing and production, and at the same time make the internal space of the bottle body 31 fully available for filling the cleaning agent.

[0063] Further, the bottle body 31 and the bottle cap 32 can be detachably connected by means of threaded connection, snap connection, bonding and other structural methods. Since there are various relevant structural methods, the present invention does not limit this; for the convenience of understanding, in this embodiment, the bottle body 31 and the bottle cap 32 can be threadedly connected.

[0064] Refer to the appendix Figure 1 , appendix Figure 2 and appendix Figure 17 , the bottle cap 32 is provided with a concave cavity 321, the diversion hole 301 is arranged on the bottom wall of the concave cavity 321, and the first buoyancy plug 1 is placed in the concave cavity 321 when it does not float; this design can increase the overall aesthetic feeling, and at the same time provide a moving space for the first buoyancy plug 1 to prevent the first buoyancy plug 1 from being exposed outside.

[0065] Refer to the appendixFigure 4 - Attachment Figure 6 and attachment Figure 12 - Attachment Figure 14 , the axis lines of the air pressure holes 302 and the diversion holes 301 are both vertically designed so that the gas flow direction and the liquid flow direction are kept in the same plane, and this design can ensure more stable liquid exchange.

[0066] Refer to the attachment Figure 4 - Attachment Figure 6 , attachment Figure 12 - Attachment Figure 14 and attachment Figure 17 , a pressing rod 322 is provided inside the bottle cap 32, and the pressing rod 322 extends into the bottle body 31 and presses against the cleaning agent; this design can play a role in fixing the cleaning agent and prevent the cleaning agent from shaking randomly in the accommodating cavity 30.

[0067] Refer to the attachment Figure 2 , a connecting block 323 is provided at the top of the bottle cap 32, and a rope hole 3230 for installing a hanging rope (not shown in the figure) is provided on the connecting block 323.

[0068] Specifically, one end of the hanging rope is installed on the connecting block 323, and the other end is placed outside the water tank, which is convenient for the user to place the bottle body 3 into or take it out of the water tank through the hanging rope, avoiding the user from putting their hands into the water tank and getting their hands dirty, and improving the use experience.

[0069] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
