Description

TECHNICAL FIELD

[0001] The utility model relates to the field of daily hygiene, especially a kind of quantitative release device of toilet cleaning material. BACKGROUND

[0002] In daily life, the cleaning and hygiene of toilet are very important. In order to maintain the cleaning of toilet and reduce stain residue, toilet cleaning material automatic release device emerges as the times require. This kind of device is usually placed in toilet water tank and automatically releases cleaning material when toilet flushes, thereby helping to clean various stains in toilet.

[0003] At present, a common toilet cleaning material automatic release technology on the market is to place solid cleaning material at the bottom of toilet water tank. After water tank is filled with water, the solid cleaning material will gradually dissolve in water to generate cleaning mixture. When toilet is drained, the cleaning mixture will be released from the upper opening of automatic release device and enter toilet with water flow to play a cleaning role. However, this prior art has many obvious defects.

[0004] Firstly, when cleaning mixture is released in water at a certain concentration, accumulation phenomenon will occur, especially in winter. Because of low water temperature, the diffusion speed of cleaning mixture slows down and it is more likely to gather around cleaning material. A large amount of mixed cleaning liquid is accumulated inside the automatic release device, and only a small amount can really participate in the cleaning work of toilet. This not only causes waste of cleaning material, but also greatly reduces the cleaning effect, which cannot meet the user's requirement for toilet cleanliness.

[0005] Secondly, in the prior art, the solid cleaning material is directly connected with water in the water tank. With the passage of time, the solid cleaning material will be continuously released. In the case of using toilet at a long interval, the over-released cleaning material in the early stage will significantly reduce the subsequent use times. This means that the user needs to frequently replace the cleaning material, which increases the use cost and also makes the service life of cleaning material difficult to control, bringing great inconvenience to the user.

[0006] In summary, the existing toilet cleaning material automatic release technology has problems such as accumulation of cleaning mixture, waste of cleaning material, poor cleaning effect and uncontrollable service life. These problems seriously affect the user's experience and also limit the further development of this kind of product. Therefore, there is an urgent need for a new type of toilet cleaning material automatic release device to overcome the shortcomings of the prior art and achieve more efficient, more stable and more economical toilet cleaning effect. This new device not only can avoid the accumulation of cleaning mixture and ensure that cleaning material fully plays a role, but also can accurately control the release amount of cleaning material and prolong its service life, thereby providing the user with a more convenient and high-quality toilet cleaning solution. UTILITY MODEL CONTENT

[0007] The technical problem to be solved by this utility model is to provide a quantitative release device for toilet cleaning substances. This utility model eliminates complex electronic and mechanical components and adopts a simple and effective physical principle to realize that the cleaning substances automatically mix with water when the toilet is flushed and enter the toilet cavity to wash away stains, which greatly reduces production costs and improves the stability and reliability of the product.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: a quantitative release device for toilet cleaning substances, characterized in that it includes a base and a buoyancy valve core. The base has a hollow cavity inside, and a dividing layer is provided inside the base to divide the cavity into an upper cavity and a lower cavity. The lower cavity is connected to the toilet tank, and the cleaning substance is provided in the upper cavity. A guide post is provided on the dividing layer for the insertion of the buoyancy valve core. The buoyancy valve core moves downward to connect the upper cavity and the lower cavity. When the upper and lower chambers are connected, the buoyancy valve core moves to its highest position, separating the upper and lower chambers. When the water level rises from a low level, the upper and lower chambers connect. As the water level rises, water from the toilet tank enters through the lower chamber and flows into the upper chamber. The water and cleaning agents mix to form a cleaning solution until the buoyancy valve core moves to its highest position. When the water level drops from a high level, the buoyancy valve core moves down, and the cleaning solution flows from the upper chamber into the lower chamber, eventually being released into the toilet tank.

[0009] A further preliminary embodiment of this utility model is as follows: the guide column is provided with a water passage hole, and the lower cavity is provided with a connecting channel to the outside; the lower end of the buoyancy valve core is provided with a sealing cap, the buoyancy valve core is inserted into the guide column and can move up and down with the water level, and there is a gap between the outer wall of the buoyancy valve core and the inner wall of the guide column; when the water level is low, the buoyancy valve core is in a low position, the sealing cap and the guide column are not closed, water passes through the gap and enters the upper cavity through the water passage hole to mix with the cleaning agent to form a cleaning mixture; when the water level rises, the sealing cap and the guide column move closer to each other until they are closed, and water no longer enters the upper cavity; when the water level drops from a high level, the sealing cap and the guide column gradually open, and the cleaning mixture in the upper cavity enters the lower cavity through the water passage hole and the gap, and is finally released into the toilet tank through the connecting channel.

[0010] A further preliminary option of this utility model is: the buoyancy valve core is hollow, and there are multiple water passage holes arranged longitudinally on the side wall of the guide column.

[0011] A further preliminary option of this utility model is: the dividing layer has an arc-shaped structure, and the outer end of the dividing layer extends to the bottom of the substrate, making the lower cavity hemispherical.

[0016] The utility model further preselected scheme is: the sealing protrusion is inserted into the sealing recess and realizes the sealing in the opening of the guide cylinder lower end of the split layer.

[0017] The utility model further preselected scheme is: the buoyancy valve core includes upper cylinder and lower cylinder, and the size of lower cylinder is less than upper cylinder, and the gap is located between the outer wall of lower cylinder and the inner wall of guide cylinder.

[0018] The utility model further preselected scheme is: the outer diameter of upper cylinder gradually reduces from top to bottom, and the inner diameter of guide cylinder gradually reduces from top to bottom;The gap between upper cylinder and guide cylinder gradually reduces to completely seal in the process of the lower movement of buoyancy valve core;The gap between upper cylinder and guide cylinder gradually enlarges in the process of the upper movement of buoyancy valve core.

[0019] Compared with the prior art, the device of the utility model cleverly controls the communication or separation of upper and lower cavities through the up and down movement of buoyancy valve core, effectively avoids the accumulation of cleaning mixture. When the water level rises, water gradually enters the upper cavity and mixes with the cleaning material, when the water level decreases, all cleaning mixture in the upper cavity will be discharged, even if the cleaning mixture accumulation phenomenon occurs, it will not affect its discharge, and more cleaning mixture is ensured to participate in the cleaning of the closestool. At the same time, it can also accurately control the release amount of cleaning material, when the water level decreases from high water level, the buoyancy valve core moves down, and the cleaning mixture enters the lower cavity from the upper cavity and is released to the water tank, the water inlet and outlet amount is fixed, and the cleaning mixture reaches a certain concentration and will greatly slow down the dissolution speed, and long-time placement can also greatly slow down the dissolution time.

[0026] The utility model will be described further in detail below in combination with the drawings.

[0027] As Figures 1-6 shown, a kind of toilet cleaning material quantitative release device, including base body 1 and floating valve core 2, the cavity of hollow inside base body 1, base body is provided with division layer 3 inside, division layer 3 is divided into upper cavity 31 and lower cavity 32 by cavity, lower cavity 32 is connected with toilet water tank, upper cavity 21 is provided with cleaning material 4, cleaning material 4 is generally solid or gel, division layer 3 is provided with the guide column body 5 that can be inserted by floating valve core, floating valve core 2 moves down to make upper cavity 31 and lower cavity 32 communicate, floating valve core 2 moves up to the highest place, so that upper cavity 31 and lower cavity 32 are separated;When water level rises from low water level, upper cavity 31 and lower cavity 32 communicate, with the rising of water level, the water of toilet water tank enters into upper cavity 31 by lower cavity 32, water and cleaning material are mixed to form cleaning mixture, until floating valve core 2 moves up to the highest position;When water level drops from high water level, floating valve core 2 moves down, cleaning mixture enters lower cavity 31 from upper cavity 32, and is finally released into toilet water tank.

[0028] Avoid cleaning mixture accumulation: device is communicated or separated by the up-down movement of floating valve core 2 to control upper and lower cavities, so that water and cleaning material are mixed under specific water level condition.When water level rises, water gradually enters upper cavity 31 and mixes with cleaning material 4, and when water level drops, all cleaning mixture in upper cavity 21 is discharged, even if there is accumulation phenomenon, it does not affect the discharge, ensuring more cleaning mixture to participate in toilet cleaning.

[0029] Accurate control of the amount of cleaning substance released: when the water level drops from high water level, the buoyancy valve core 2 moves down, and the cleaning mixture enters the lower cavity 32 from the upper cavity 31 and is released to the water tank, which means that the release of cleaning substances is orderly based on water level changes, and the amount of water entering and leaving is fixed and unchanged. The cleaning mixture will significantly slow down the dissolution to a certain concentration, and even if it is left for a long time, the dissolution time will be significantly slowed down. As long as the volume of the upper cavity 31 is controlled, the amount of cleaning substance released can be controlled. Unlike the continuous and uncontrolled release of solid cleaning substances in the prior art, this device can effectively control the amount of cleaning substance released, avoid the lack of cleaning substances due to excessive release in the early stage, thereby prolonging the service life of the cleaning substance, increasing the number of uses, and reducing the frequency and cost of users replacing the cleaning substance.

[0030] The guide column 5 is provided with a water passage hole 6, and the lower cavity is provided with a communication channel 7 connected to the outside; the lower end of the buoyancy valve core 2 is provided with a sealing cover 8, the buoyancy valve core 2 is inserted into the guide column 5 and can move up and down with the change of water level, and there is a gap 10 between the outer wall of the buoyancy valve core 2 and the inner wall of the guide column 5; when the water level is low, the buoyancy valve core 2 is at a low position, the sealing cover 8 and the guide column 5 are not closed, and the water passes through the gap 10 and enters the upper cavity through the water passage hole 6 and mixes with the cleaning substance 4 to form a cleaning mixture; when the water level rises, the sealing cover 8 and the guide column 5 approach each other until they close, and the water no longer enters the upper cavity; when the water level decreases from high position, the sealing cover 8 and the guide column 5 gradually open, and the cleaning mixture in the upper cavity enters the lower cavity through the water passage hole 6 and the gap, and is finally released to the outside through the communication channel 7. Through the ingenious design of the base 1, the partition layer 3, the buoyancy valve core 2 and other structures, the automatic mixing and release of the cleaning substance 4 and water are realized. This way of controlling the generation and discharge of cleaning mixture based on water level changes does not require complex electronic or mechanical control systems, simplifies the device structure and reduces production costs. At the same time, since the water inlet and outlet speed of the toilet is constant, the same volume of cleaning mixture can be discharged each time, making the service life of the device predictable.

[0031] The buoyancy valve core 2 is hollow. The hollow setting of the buoyance valve core 2 reduces the weight of the valve core itself, making it more sensitive to water level changes. The buoyancy of the buoyance valve core 2 increases with the increase of water surface height, rather than remaining unchanged. It can timely control the generation and stop of the cleaning mixture, further optimize the mixing time of the cleaning material 4 and water, and improve the overall performance of the device. The water passage hole 6 is arranged in the side wall of the guide column 5 in a longitudinal direction. The multiple water passage holes 6 are arranged in the side wall of the guide column 5 in a longitudinal direction, and the effect can be achieved by passing through the corresponding water passage hole 6 at different water levels, so as to form and discharge the cleaning mixture. The split layer 3 is in an arc shape, and the outer end of the split layer 3 extends to the bottom of the base body 1, so that the lower cavity is in a semispherical shape. The split layer 3 adopts an arc shape and the outer end extends to the bottom of the base body 1, so that the lower cavity is in a semispherical shape. This design is beneficial to the flow and convergence of water flow in the lower cavity, avoids water flow dead angle, ensures that the cleaning mixture can be smoothly released to the outside through the communication channel 7, and improves the discharge efficiency.

[0032] The base body 1 is provided with a cover 9 above. The base body 1 is provided with a cover 9 above, which can effectively prevent the cleaning material 4 from being polluted by external impurities when not in use, protect the purity and performance of the cleaning material 4, prolong the service life of the cleaning material 4, and ensure the stability of the cleaning effect. The cover 9 is provided with an openable lid. The cover 9 is provided with an openable lid, which is simple and convenient to operate, improves the user experience, and increases the practicality of the device.

The water passage hole 6 is arranged in a longitudinal direction, the communication channel 7 is provided with four, and the guide column 5 and the buoyance valve core 2 are both in a cylindrical shape. This standardized and regular structure design is convenient for mold manufacturing and batch production, further reduces the production cost, at the same time ensures the cooperation precision between the parts of the device, improves the overall performance and stability of the device. The split layer 3 is provided with a sealing protrusion 11 at the opening of the lower end of the guide column, and the sealing cover 8 is provided with a sealing groove 12, and the sealing protrusion 11 is inserted into the sealing groove 12 to realize sealing. This structure design greatly improves the reliability and stability of the sealing, which can effectively prevent water from flowing into or out of the upper cavity without control during the water level change. Figure 6As shown, the buoyant valve core 2 comprises an upper cylinder 13 and a lower cylinder 14, the size of the lower cylinder 14 is smaller than the upper cylinder 13, the gap 10 is located between the outer wall of the lower cylinder 14 and the inner wall of the guide cylinder 5, and the unique structure of the buoyant valve core optimizes the water flow passage.

[0034] The outer diameter of the upper cylinder 13 is gradually reduced from top to bottom, and the inner diameter of the guide cylinder 5 is gradually reduced from top to bottom; during the downward movement of the buoyant valve core 2, the gap between the upper cylinder 13 and the guide cylinder 5 is gradually reduced to complete sealing, and the water passage hole 15 at the position of the upper cylinder is opened to closed during the downward movement; during the upward movement of the buoyant valve core 2, the gap between the upper cylinder 13 and the guide cylinder 5 is gradually enlarged, and the water passage hole 15 at the position of the upper cylinder is closed to opened during the upward movement, and finally the sealing effect is realized by the sealing cover 8, so that the formation and discharge of the cleaning material mixed liquid can be quantitatively controlled.
