Description

Technical Field

[0001] The invention relates to the technical field of toilet cleaning agent release devices, and in particular to a toilet cleaning liquid quantitative release device. Background Art

[0002] Solid toilet cleaner is a cleaning product containing detergent, fragrance and disinfectant. When using it, you only need to put it into the toilet tank. The solid toilet cleaner dissolves in the water to form toilet cleaning liquid. Every time you flush the toilet, it can deodorize, sterilize and clean the toilet, and make the water appear clean blue.

[0003] The Chinese patent application (authorization announcement number CN207727704U) discloses a solid toilet cleaner concentration constant release device, comprising a hollow shell with an open upper end, an inlet and an outlet respectively connected to the inner cavity of the shell are provided at the bottom of the shell, and a one-way valve and a one-way throttle valve are respectively installed, support ribs are evenly distributed along the circumferential direction on the inner wall of the shell, and support bosses are respectively provided at the lower ends of some or all of the support ribs evenly distributed along the circumference and located at the bottom of the shell, and the support bosses are arranged radially along the inner cavity of the shell; an inner cylinder is inserted into the shell; the inner cylinder is matched with the inner diameter clearance of the support ribs evenly distributed along the circumference, the bottom of the inner cylinder is supported on the support boss, and a plurality of long holes or a plurality of water-permeable holes are evenly distributed along the circumferential direction on the upper part of the inner cylinder, or a plurality of water-permeable holes are provided at the bottom of the inner cylinder and a filter mesh interlayer is provided. The beneficial effect is: the dissolution rate of the solid toilet cleaner can be controlled, and then the concentration of the toilet cleaner contained in the water body in the water tank can be controlled, so that the concentration of the toilet cleaner is constant, thereby ensuring the deodorization and sterilization effect of each flushing.

[0004] The concentration of the liquid released each time by the above technical solution is constant, but as the solid toilet cleaner inside dissolves, the volume of the solid toilet cleaner will decrease, resulting in a gradual increase in the amount of clean water entering the interior each time. As the solid toilet cleaner dissolves, the amount of toilet cleaner liquid with a constant concentration released gradually increases. This results in the concentration of the toilet cleaner liquid in the toilet tank gradually increasing, making it impossible to release the toilet cleaner liquid evenly and effectively. At the same time, as the amount of clean water gradually increases, the dissolution rate of the solid toilet cleaner will also increase, reducing durability and increasing the cost of use.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention realizes precise control of the release amount of solid toilet cleaner through the synergistic effect of the stabilizing shrink sleeve and the pushing and compressing mechanism. As the solid toilet cleaner dissolves and its volume decreases, the stabilizing shrink sleeve shrinks synchronously to keep a close fit with the solid toilet cleaner, thereby preventing the problem of uneven liquid concentration caused by the volume change of the solid toilet cleaner. At the same time, the pushing and compressing mechanism pushes the solid toilet cleaner to move upward and automatically fills the bottom space, effectively balancing the liquid intake, avoiding the concentration dilution caused by the entry of excessive clean water, thereby extending the service life of the solid toilet cleaner and reducing the cost of use.

[0018] 2. The present invention can evenly release the toilet cleaning liquid in the liquid storage shell through the circulation release head, ensuring that it can be fully mixed with the water every time the water is flushed, thereby improving the cleaning effect. By accurately controlling the release amount and concentration of the toilet cleaning liquid, the problem of incomplete cleaning or excessive waste caused by uneven concentration is avoided, so that the toilet cleaning liquid in the toilet tank is always maintained within a stable and effective concentration range, ensuring the overall cleaning effect and user satisfaction.

[0019] 3. The present invention realizes intelligent regulation of the dissolution process of solid toilet cleaners through an adaptive release mechanism. Users only need to put the solid toilet cleaner into a stable shrink sleeve when using it for the first time, and simply set it up through the limit pressing cover and the limit adjustment frame, so that there is no need for frequent adjustments during subsequent use. As the solid toilet cleaner continues to dissolve, it can automatically adapt to its volume changes and maintain a stable release amount and concentration, which greatly simplifies the operation process and improves the user's convenience. At the same time, this intelligent adjustment mechanism also reduces the risk of equipment failure or performance degradation due to improper human operation, and improves the reliability and stability of the equipment.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] See also Figures 1 to 13As shown, the quantitative release device of toilet cleaning liquid is installed on the inner wall of the toilet water tank, including a liquid storage shell 2, a shrinkage adjustment chamber 3, a limit pressing cover 4, a circulation release head 5 and a limit adjustment frame 6; the limit adjustment frame 6 is installed on the inner wall of the toilet water tank; the liquid storage shell 2 is installed on the limit adjustment frame 6, and the liquid storage shell 2 is used to receive a rated amount of water entering from the toilet water tank; the shrinkage adjustment chamber 3 is installed inside the liquid storage shell 2, and the shrinkage adjustment chamber 3 is composed of a stable shrinkage sleeve 31 and a push-up compression mechanism 32. The axial position of the stable shrinkage sleeve 31 is provided with a storage space for storing the solid toilet cleaning agent 1, the stable shrinkage sleeve 31 is tightly fitted with the solid toilet cleaning agent 1, the push-up compression mechanism 32 is installed at the bottom of the stable shrinkage sleeve 31, and the working end of the push-up compression mechanism 32 conflicts with the bottom of the solid toilet cleaning agent 1; the limit pressing cover 4 is installed on the top of the liquid storage shell 2; the circulation release head 5 is installed at the bottom of the liquid storage shell 2, and the circulation release head 5 is connected with the shrinkage adjustment chamber 3.

[0036] The liquid storage shell 2 is mounted on the limit adjustment frame 6 and is vertically arranged inside the toilet tank and maintained at a specified water level. The liquid storage shell 2 is used to store the toilet cleaning liquid generated by the reaction of the solid toilet cleaner 1 and water. The shrinkage adjustment chamber 3 is located inside the liquid storage shell 2 and is composed of a stable shrinkage sleeve 31 and a push-up compression mechanism 32. A storage space is provided inside the stable shrinkage sleeve 31 for storing the solid toilet cleaner 1 and fitting tightly with the solid toilet cleaner 1. The push-up compression mechanism 32 is located at the bottom of the stable shrinkage sleeve 31 and conflicts with the bottom of the solid toilet cleaner 1, and is used to provide an upward thrust when the volume of the solid toilet cleaner 1 is reduced.

[0037] Before use, the user needs to open the liquid storage housing 2 through the limit pressing cover 4, stack the solid toilet cleaner 1 and put it in, and adjust the stable shrink sleeve 31 and the push-up compression mechanism 32 so that the solid toilet cleaner 1 is tightly wrapped in the stable shrink sleeve 31. With each water inflow into the toilet tank, the water enters the push-up compression mechanism 32 through the circulation release head 5, and then penetrates into the gap between the stable shrink sleeve 31 and the solid toilet cleaner 1, reacts with the solid toilet cleaner 1, and generates toilet cleaning liquid. The toilet cleaning liquid accumulates inside the liquid storage housing 2 until it reaches a predetermined concentration.

[0038] When the toilet is flushed, the water inside the water tank flows out quickly, forming a suction force, causing the toilet cleaning liquid inside the liquid storage housing 2 to flow out through the shrink sleeve, the push-up compression mechanism 32 and the circulation release head 5, and mix with the water inside the water tank. The circulation release head 5 evenly releases the toilet cleaning liquid to improve the mixing effect with the water liquid.

[0039] As the solid toilet cleaner 1 is continuously used, its volume gradually decreases. At this time, the stabilizing shrink sleeve 31 will shrink synchronously and keep close contact with the outer wall of the solid toilet cleaner 1. At the same time, the push-up compression mechanism 32 will push the solid toilet cleaner 1 upward and automatically fill the excess space between the bottom of the solid toilet cleaner 1 and the storage space. This ensures the effective use of the storage space, thereby balancing the amount of water entering the liquid and controlling the release amount of the solid toilet cleaner 1.

[0040] The toilet cleaning liquid quantitative release device realizes precise control of the release amount of the solid toilet cleaning agent 1 through the synergistic effect of the stabilizing shrink sleeve 31 and the pushing and compressing mechanism 32, effectively saves the usage of the solid toilet cleaning agent 1, extends the service life, ensures the uniformity of the concentration of the cleaning liquid and the water liquid, and improves the use effect.

[0041] See also Figures 3 to 8 As shown, a water quantitative chamber 22 is provided at the top of the liquid storage shell 2, a mounting port is provided at the bottom of the water quantitative chamber 22, a plurality of guide brackets 25 are provided on the mounting port, a mounting chamber 23 is provided below the water quantitative chamber 22, a water level identification mark 21 is provided on the outside of the liquid storage shell 2, and a rotating slot 24 is also provided on the top of the liquid storage shell 2.

[0042] The rotating slot 24 is used for clamping and installing the position limiting pressing cover 4 .

[0043] The liquid storage housing 2 is mounted on the limit adjustment frame 6 and is vertically arranged inside the toilet tank. The water level identification mark 21 provides installation identification for the user to ensure that it is located at the specified water level line position. The water quantitative chamber 22 of the liquid storage housing 2 is located at the top, and a mounting port is provided at the bottom thereof, and a plurality of guide brackets 25 are provided on the mounting port. The mounting chamber 23 is located below the water quantitative chamber 22, providing the necessary installation space for the entire device.

[0044] Before use, the user needs to open the liquid storage housing 2 through the limit pressing cover 4. Then, the solid toilet cleaner 1 is guided to the installation port through the guide bracket 25, and with the cooperation of the limit pressing cover 4 and the stable shrink sleeve 31, the solid toilet cleaner 1 is stably pressed into the inside of the stable shrink sleeve 31. The stable shrink sleeve 31 has a storage space inside for tightly wrapping the solid toilet cleaner 1.

[0045] With each water inflow into the toilet tank, the water quantitative chamber 22 is used to quantitatively store enough water, and then the solid toilet cleaning agent 1 penetrates through the installation port. The water reacts with the solid toilet cleaning agent 1 to generate toilet cleaning liquid. The generated toilet cleaning liquid accumulates inside the liquid storage housing 2 until it reaches a predetermined concentration.

[0046] See also Figures 3 to 13As shown, the stabilizing shrink sleeve 31 includes an elastic sleeve 311 installed in the installation port, a plurality of limit contact rods 312 are distributed on the inner wall of the elastic sleeve 311, and a limit hook 3121 is provided on the top of the limit contact rod 312. The stabilizing shrink sleeve 31 also includes a synchronous adjustment component 313 installed in the installation chamber 23, and the telescopic end of the synchronous adjustment component 313 is connected to the limit contact rod 312.

[0047] The elastic sleeve 311 is installed at the installation port, has contraction elasticity, and can tightly wrap the solid toilet cleaner 1. The limiting contact rods 312 arranged at intervals on the inner wall are connected to the synchronous adjustment component 313, and the synchronous adjustment component 313 is located in the installation chamber 23.

[0048] During the placement of the solid toilet cleaner 1, the synchronous adjustment component 313 drives the limit contact rod 312 to move synchronously through telescopic movement, thereby expanding and adjusting the elastic sleeve 311. This expansion adjustment allows the user to easily place the solid toilet cleaner 1 inside the elastic sleeve 311. When the solid toilet cleaner 1 is completely placed, the elastic sleeve 311 returns to the contracted state under the action of its own elastic force, driving the limit contact rod 312 to tightly contact the solid toilet cleaner 1.

[0049] At this time, the limiting resistance rod 312 not only ensures a stable and appropriate flow gap between the elastic sleeve 311 and the solid toilet cleaner 1, which is convenient for water to penetrate and react with the solid toilet cleaner 1, but also limits the position of the solid toilet cleaner 1 through the limiting hook 3121, thereby enhancing the stability of the solid toilet cleaner 1 placed inside the elastic sleeve 311.

[0050] As the volume of the solid toilet cleaner 1 gradually decreases during use, the elastic sleeve 311 will shrink accordingly to maintain a close fit with the outer wall of the solid toilet cleaner 1. The synchronous adjustment component 313 will automatically adjust the position of the limit resistance rod 312 according to the shrinkage of the elastic sleeve 311, thereby ensuring that the entire stable shrink sleeve 31 can continue to effectively wrap the solid toilet cleaner 1 and maintain the stability of the water flow gap.

[0051] See also Figures 9 to 13As shown, the synchronous adjustment component 313 includes a limit mounting plate 3131 installed in the mounting chamber 23, the limit mounting plate 3131 is fixedly connected to the liquid storage housing 2, a plurality of limit sliding grooves 3132 are arranged on the limit mounting plate 3131, a rotating adjustment plate 3133 is rotatably installed at the bottom of the limit mounting plate 3131, a plurality of adjustment bevels 3134 are arranged on the rotating adjustment plate 3133, and a movable adjustment block 3135 is installed in each limit sliding groove 3132, and the movable adjustment block 3135 is connected to the limit The slide groove 3132 is slidably connected, and a resistance shaft 3136 is provided at the bottom of the movable adjustment block 3135. A telescopic connecting rod 3137 is installed on the top of the movable adjustment block 3135. The end of the telescopic connecting rod 3137 away from the movable adjustment block 3135 is fixedly connected to the limit resistance rod 312. The synchronous adjustment component 313 also includes an adjustment sleeve 3138 installed on the liquid storage shell 2. The adjustment sleeve 3138 is rotatably connected to the liquid storage shell 2, and the inner wall of the adjustment sleeve 3138 is fixed to the rotating adjustment disk 3133.

[0052] When the solid toilet cleaner 1 needs to be placed, the user drives the rotating adjustment disk 3133 to rotate by turning the adjustment sleeve 3138. The rotation of the rotating adjustment disk 3133 causes the adjustment bevel 3134 thereon to come into conflict with the abutment shaft 3136, thereby pushing the abutment shaft 3136 and the movable adjustment block 3135 to move along the limiting slide groove 3132. As the movable adjustment block 3135 moves, the telescopic connecting rod 3137 is stretched, thereby driving the limiting abutment rod 312 to move synchronously, thereby realizing the expansion of the elastic sleeve 311.

[0053] The synchronous movement of the plurality of limiting and resisting rods 312 acts together on the elastic sleeve 311, so that it can expand smoothly to adapt to the size of the solid toilet cleaner 1, and it is convenient for the user to put the solid toilet cleaner 1 into the elastic sleeve 311. After the solid toilet cleaner 1 is placed, the elastic sleeve 311 returns to the contracted state under the action of its own elastic force, and the synchronous adjustment component 313 automatically adjusts the position of the limiting and resisting rod 312 according to the contraction of the elastic sleeve 311 through the interaction of the movable adjustment block 3135, the telescopic connecting rod 3137 and the limiting and resisting rod 312, so as to maintain a close fit with the outer wall of the solid toilet cleaner 1 and maintain a suitable water flow gap.

[0054] See also Figures 6 to 10As shown, the push-up compression mechanism 32 includes a push assembly 321 installed inside the installation chamber 23, the extended end of the push assembly 321 extends into the interior through the stabilizing shrink sleeve 31, the bottom of the push assembly 321 is connected to the circulation release head 5, and an airbag filling mechanism 322 is also installed on the push assembly 321. During the use of the solid toilet cleaner 1, as its volume gradually decreases due to chemical reactions, the stabilizing shrink sleeve 31 will shrink accordingly to maintain a close fit with the outer wall of the solid toilet cleaner 1. At the same time, the push assembly 321 will perform real-time push-up adjustments according to the actual size of the solid toilet cleaner 1. When the volume of the solid toilet cleaner 1 is reduced, the push assembly 321 will move upward accordingly to continuously apply an upward thrust to the solid toilet cleaner 1.

[0055] When the pushing assembly 321 pushes and adjusts the shrunk solid toilet cleaner 1, a certain space may be formed between the bottom of the solid toilet cleaner 1 and the stabilizing shrink sleeve 31. In order to fill this space and avoid the accumulation of excess water in the stabilizing shrink sleeve 31, the pushing and compressing mechanism 32 is also equipped with an airbag filling mechanism 322. The airbag filling mechanism 322 can expand adaptively to fill the formed space, thereby effectively adjusting the position of the solid toilet cleaner 1 and avoiding the generation of excess space.

[0056] The push-up compression mechanism 32 not only ensures the stability and position accuracy of the solid toilet cleaning agent 1 during use, but also avoids the accumulation of excess water, thereby improving the use efficiency and effect of the entire toilet cleaning liquid quantitative release device.

[0057] See also Figures 8 to 10 As shown, the pushing assembly 321 includes a limiting mounting sleeve 3212 fixedly mounted inside the liquid storage shell 2, a pushing telescopic tube 3211 is mounted inside the limiting mounting sleeve 3212, a pushing block is provided on the top of the pushing telescopic tube 3211, an elastic hose 3214 is mounted on the bottom of the pushing telescopic tube 3211, one end of the elastic hose 3214 away from the pushing telescopic tube 3211 is connected to the flow release head 5, and a first spring 3213 is installed between the limiting mounting sleeve 3212 and the pushing telescopic tube 3211.

[0058] The limiting installation sleeve 3212 is fixedly installed inside the liquid storage housing 2, and plays a role in limiting and supporting the pushing telescopic tube 3211. The pushing telescopic tube 3211 and the limiting installation sleeve 3212 are connected in a sliding manner to ensure that the pushing telescopic tube 3211 can move freely along the axial direction of the limiting installation sleeve 3212.

[0059] During the use of the solid toilet cleaner 1, as its volume gradually decreases due to chemical reactions, the stabilizing shrink sleeve 31 will shrink accordingly to maintain a close fit with the outer wall of the solid toilet cleaner 1. At this time, the top of the pushing telescopic tube 3211 will move toward the inside of the stabilizing shrink sleeve 31 to adapt to the change in the volume of the solid toilet cleaner 1. The pushing block is located at the top of the pushing telescopic tube 3211, and moves with the movement of the pushing telescopic tube 3211, continuously applying an upward thrust to the solid toilet cleaner 1, ensuring that the solid toilet cleaner 1 maintains a stable position during use.

[0060] The bottom of the push-pull telescopic tube 3211 is connected to the circulation release head 5 through the elastic hose 3214. The elastic hose 3214 has the characteristics of being foldable and stretchable, and can be stretched and retracted accordingly with the movement of the push-pull telescopic tube 3211. At the same time, the push-pull telescopic tube 3211 and the elastic hose 3214 are kept in communication to ensure that the water can flow smoothly. The elastic hose 3214 effectively reduces the overall size of the assembly and improves the flexibility and adaptability of the assembly.

[0061] The first spring 3213 is installed between the limiting installation sleeve 3212 and the pushing telescopic tube 3211, and plays a role in pushing the pushing telescopic tube 3211. When the volume of the solid toilet cleaner 1 is reduced, the first spring 3213 will push the pushing telescopic tube 3211 to move upward to continuously apply a thrust to the solid toilet cleaner 1. This ensures that the pushing component 321 can make real-time pushing adjustments according to the actual size of the solid toilet cleaner 1, and maintain the stability and position accuracy of the solid toilet cleaner 1 during use.

[0062] See also Figures 8 to 10 As shown, the airbag filling mechanism 322 includes a filling airbag 3221 arranged inside the stabilizing shrink sleeve 31, and a plurality of support bars are distributed on the outside of the filling airbag 3221. The filling airbag 3221 is fixedly connected to the pushing telescopic tube 3211. The airbag filling mechanism 322 also includes an inflatable airbag 3223 installed on the outside of the limiting mounting sleeve 3212, a connecting tube 3224 is installed between the inflatable airbag 3223 and the filling airbag 3221, a pushing plate 3225 is installed at the bottom of the inflatable airbag 3223, and a second spring 3226 is installed between the pushing plate 3225 and the limiting mounting sleeve 3212.

[0063] The filling airbag 3221 is arranged inside the stable shrink sleeve 31, and a plurality of support strips are distributed on the outside thereof, which are used to fit the bottom of the solid toilet cleaning agent 1 when the filling airbag 3221 expands, and ensure that a certain flow gap is maintained between the solid toilet cleaning agent 1 and the filling airbag 3221, so that the water can flow smoothly. The filling airbag 3221 is fixedly connected to the pushing telescopic tube 3211, and the corresponding telescopic changes are made as the pushing telescopic tube 3211 moves. At the same time, the inflatable airbag 3223 is installed on the outside of the limit installation sleeve 3212, and is connected to the filling airbag 3221 through the connecting pipe 3224. The inflatable airbag 3223 is used to store air and transport gas to the filling airbag 3221 through the connecting pipe 3224. The pushing plate 3225 is installed at the bottom of the inflatable airbag 3223, and a second spring 3226 is installed between the pushing plate 3225 and the limit installation sleeve 3212. The second spring 3226 pushes the pushing plate 3225 , thereby continuously pushing the inflatable airbag 3223 , so that the air in the inflatable airbag 3223 is squeezed into the filling airbag 3221 through the connecting tube 3224 .

[0064] During the use of the solid toilet cleaner 1, as its volume gradually decreases due to chemical reactions, the push assembly 321 will make real-time push adjustments according to the actual size of the solid toilet cleaner 1. When the volume of the solid toilet cleaner 1 decreases, the push assembly 321 will move upward to continuously apply an upward thrust to the solid toilet cleaner 1. At this time, if a certain space is formed between the bottom of the solid toilet cleaner 1 and the stabilizing shrink sleeve 31, the filling airbag 3221 will expand accordingly.

[0065] The expansion of the filling airbag 3221 is achieved by the air in the inflatable airbag 3223 being pushed by the second spring 3226 and transported to the filling airbag 3221 through the connecting pipe 3224. As the filling airbag 3221 expands, the support strips on the outside thereof will fit the bottom of the solid toilet cleaner 1, filling the excess space and preventing excess water from being retained inside the stabilizing shrink sleeve 31.

[0066] See also Figures 1 to 4 As shown, the inner wall of the limit pressing cover 4 is provided with a plurality of sliding buckles 42, which are rotatably engaged with the rotating slot 24, a downward pressing push rod 41 is provided at the axial position of the limit pressing cover 4, and a vent hole 43 is also provided on the limit pressing cover 4.

[0067] During the installation of the limit pressing cover 4, the user first aligns the limit pressing cover 4 with the liquid storage housing 2 so that the sliding buckle 42 is aligned with the rotating slot 24. Then, by rotating or pushing the limit pressing cover 4, the sliding buckle 42 is rotated and engaged along the track of the rotating slot 24 until the limit pressing cover 4 is completely fixed on the liquid storage housing 2. This rotating engagement method not only improves the convenience of installation, but also ensures the stability of the limit pressing cover 4 during use.

[0068] In addition, a downward push rod 41 is provided at the axial position of the limit pressing cover 4. The downward push rod 41 is designed to provide the necessary thrust during the installation of the solid toilet cleaner 1. When the user needs to install the solid toilet cleaner 1 inside the stable shrink sleeve 31, the solid toilet cleaner 1 is first guided to the installation port of the liquid storage shell 2 through the guide bracket 25. Then, the user presses down the limit pressing cover 4 so that the downward push rod 41 contacts the top of the solid toilet cleaner 1 and applies a thrust. Under the action of the thrust, the solid toilet cleaner 1 is stably pressed into the inside of the stable shrink sleeve 31.

[0069] The vent hole 43 is used to reduce the air pressure and ensure the fluid flowability of the infusion in the liquid storage housing 2 .

[0070] See also Figures 1 to 5 As shown, the flow release head 5 includes a rotating elbow 51 installed at the bottom of the liquid storage shell 2, the rotating elbow 51 is connected to the push-up compression mechanism 32, and a diffusion rotating blade 52 is rotatably installed at one end of the rotating elbow 51 away from the liquid storage shell 2.

[0071] The rotating elbow 51 is connected to the push-up compression mechanism 32. One end of the rotating elbow 51 is rotatably connected to the liquid storage housing 2, allowing the water outlet direction of the rotating elbow 51 to be adjusted to optimize the water flow path. Specifically, the flow end of the rotating elbow 51 is arranged to be opposite to the water outlet of the toilet tank to ensure that during the toilet flushing process, under the suction force formed by the drop of the water level in the water tank, the toilet cleaning liquid accumulated inside the liquid storage housing 2 and the contraction adjustment chamber 3 can flow out smoothly through the rotating elbow 51.

[0072] When the toilet cleaning liquid flows out, it passes through the diffusion rotating blade 52 when passing through the end of the rotating elbow 51. The diffusion rotating blade 52 rotates due to the flow impact of the toilet cleaning liquid, which effectively promotes the diffusion of the toilet cleaning liquid and enhances the mixing effect of the toilet cleaning liquid and the water in the toilet tank, thereby achieving rapid and uniform fusion of the toilet cleaning liquid. The release efficiency of the toilet cleaning liquid is optimized, ensuring the maximum cleaning effect.

[0073] See also Figure 1 and Figure 2 As shown, the limit adjustment frame 6 includes a first anti-skid contact plate 61, two limit guide sleeves 62 are installed on the first anti-skid contact plate 61, an adjusting nut 621 is installed on the limit guide sleeve 62, and the outer wall of the limit guide sleeve 62 is provided with an anti-skid layer 622, and a threaded adjustment rod 64 and a limit guide rod 65 are respectively installed on the two limit guide sleeves 62, the threaded adjustment rod 64 is threadedly connected with the adjusting nut 621, and a second anti-skid contact plate 63 is installed at one end of the threaded adjustment rod 64 and the limit guide rod 65 away from the limit guide sleeve 62, an adjustment block 66 is installed on the outer side of the limit guide sleeve 62, and a mounting ring 67 is installed on the side of the adjustment block 66, and the mounting ring 67 is fixedly connected to the liquid storage shell 2.

[0074] The user drives the threaded adjustment rod 64 to perform telescopic movement by rotating the adjustment nut 621. At the same time, the limiting guide rod 65 provides a stable guiding effect to ensure the stability and accuracy of the entire adjustment process. The second anti-skid contact plate 63 is installed at the end of the threaded adjustment rod 64 and the limiting guide rod 65 away from the limiting guide sleeve 62. The first anti-skid contact plate 61 and the second anti-skid contact plate 63 are used to form a tight contact with the inner wall of the toilet tank, thereby achieving a stable installation of the liquid storage housing 2. By adjusting the adjustment nut 621, the user can accurately control the distance between the second anti-skid contact plate 63 and the first anti-skid contact plate 61 to adapt to the inner wall of the toilet tank of different sizes or shapes.

[0075] In addition, the adjustment block 66 is mounted on the limiting guide sleeve 62 and can be slidably adjusted on the limiting guide sleeve 62. Additional flexibility is provided, allowing the user to adjust the installation position of the liquid storage housing 2 according to actual needs. The stability of the adjustment block 66 is further enhanced by the anti-skid layer 622 on the outside of the limiting guide sleeve 62, and the anti-skid layer 622 effectively increases the friction between the adjustment block 66 and the limiting guide sleeve 62, preventing unnecessary sliding.

[0076] Finally, the mounting ring 67 is fixed to the side of the adjusting block 66 and is fixedly connected to the liquid storage housing 2. When the limit adjustment frame 6 is firmly mounted on the inner wall of the toilet tank, the liquid storage housing 2 is also firmly positioned at the designated position, ensuring the stability and reliability of the entire toilet cleaning liquid quantitative release device.

[0077] Specific working principle:

[0078] The liquid storage shell 2 is mounted on the limit adjustment frame 6 and is vertically arranged inside the toilet tank and maintained at a specified water level. The liquid storage shell 2 is used to store the toilet cleaning liquid generated by the reaction of the solid toilet cleaner 1 and water. The shrinkage adjustment chamber 3 is located inside the liquid storage shell 2 and is composed of a stable shrinkage sleeve 31 and a push-up compression mechanism 32. A storage space is provided inside the stable shrinkage sleeve 31 for storing the solid toilet cleaner 1 and fitting tightly with the solid toilet cleaner 1. The push-up compression mechanism 32 is located at the bottom of the stable shrinkage sleeve 31 and conflicts with the bottom of the solid toilet cleaner 1, and is used to provide an upward thrust when the volume of the solid toilet cleaner 1 is reduced.

[0079] Before use, the user needs to open the liquid storage housing 2 through the limit pressing cover 4, stack the solid toilet cleaner 1 and put it in, and adjust the stable shrink sleeve 31 and the push-up compression mechanism 32 so that the solid toilet cleaner 1 is tightly wrapped in the stable shrink sleeve 31. With each water inflow into the toilet tank, the water enters the push-up compression mechanism 32 through the circulation release head 5, and then penetrates into the gap between the stable shrink sleeve 31 and the solid toilet cleaner 1, reacts with the solid toilet cleaner 1, and generates toilet cleaning liquid. The toilet cleaning liquid accumulates inside the liquid storage housing 2 until it reaches a predetermined concentration.

[0080] When the toilet is flushed, the water inside the water tank flows out quickly, forming a suction force, causing the toilet cleaning liquid inside the liquid storage housing 2 to flow out through the shrink sleeve, the push-up compression mechanism 32 and the circulation release head 5, and mix with the water inside the water tank. The circulation release head 5 evenly releases the toilet cleaning liquid to improve the mixing effect with the water liquid.

[0081] As the solid toilet cleaner 1 is continuously used, its volume gradually decreases. At this time, the stabilizing shrink sleeve 31 will shrink synchronously and keep close contact with the outer wall of the solid toilet cleaner 1. At the same time, the push-up compression mechanism 32 will push the solid toilet cleaner 1 upward and automatically fill the excess space between the bottom of the solid toilet cleaner 1 and the storage space. This ensures the effective use of the storage space, thereby balancing the amount of water entering the liquid and controlling the release amount of the solid toilet cleaner 1.

[0082] The toilet cleaning liquid quantitative release device realizes precise control of the release amount of the solid toilet cleaning agent 1 through the synergistic effect of the stabilizing shrink sleeve 31 and the pushing and compressing mechanism 32, effectively saves the usage of the solid toilet cleaning agent 1, extends the service life, ensures the uniformity of the concentration of the cleaning liquid and the water liquid, and improves the use effect.

[0083] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
