Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a device for quantitative addition of cleaning agents. Background Technology

[0002] In modern sanitation facilities, the cleanliness of toilets has always been a crucial factor affecting user experience and environmental hygiene. Traditional toilets typically rely on tap water for flushing, but water alone is insufficient to thoroughly remove stubborn residues such as urine stains and scale. These residues not only cause stains to accumulate on the toilet surface but also produce odors and breed bacteria in the bathroom, negatively impacting the indoor environment and human health. To address this issue, various auxiliary cleaning products have emerged on the market, such as solid cleaning agents like blue bubble cleaner. These cleaners are usually placed inside the toilet tank and work by dissolving and mixing with the flushing water to achieve their cleaning function.

[0003] However, existing methods of using solid toilet cleaners have significant technical drawbacks. First, when users need immediate cleaning of the toilet, they must wait for the solid cleaner to dissolve after being placed in the tank before it can work, which cannot meet the need for immediate cleaning. Second, if the cleaner is left in the tank for a long time without being used promptly, a large amount of the dissolved cleaning components may be lost with each flush, resulting in resource waste and potentially inconsistent cleaning effects. Furthermore, existing technologies lack precise control over the amount of cleaner dissolved, making it inefficient to use and difficult to achieve precise dosage and uniform mixing, further limiting its practical application effectiveness.

[0004] Therefore, there is an urgent need for a detergent dispensing device that can solve the above problems. This device should precisely dissolve and evenly mix the detergent during toilet use, ensuring cleaning effectiveness while avoiding resource waste. Such a device should have the ability to precisely control the amount of detergent released and adapt to different usage frequencies, thereby improving the efficiency and reliability of toilet cleaning. Utility Model Content

[0005] The purpose of this invention is to provide a detergent dispensing device to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detergent metering device, comprising an outer cylinder, a top cover, a placement chamber, a dissolving chamber, an inner cylinder, a float, a spring, a connecting pipe, a connecting tube, and a connecting pipe, etc., wherein the specific configuration and interaction of each component constitute the core technical solution of this utility model.

[0007] This invention provides a detergent dispensing device, whose main structure includes an outer cylinder, which serves as the main outer shell of the device. The outer cylinder contains multiple functional chambers for storing, dissolving, and conveying the detergent. Further, the top of the outer cylinder is equipped with a top cover, on which an observation window made of transparent material is installed, allowing the user to monitor the storage status and dissolving process of the detergent in real time. Specifically, the outer cylinder is internally divided into a placement chamber and a dissolving chamber. The placement chamber, located at the top of the outer cylinder, stores solid detergent; the dissolving chamber, located below the placement chamber, receives the solid detergent gradually falling from the placement chamber and completes the dissolving process. A fixed cylinder is installed within the dissolving chamber, with an upper sealing ring and a lower sealing ring installed at its upper and lower ends, respectively. The upper and lower sealing rings are made of elastic material to ensure a tight seal between the dissolving chamber and the external environment, preventing liquid leakage.

[0008] Furthermore, the dissolving chamber is equipped with an inner cylinder, which serves as the core component for dissolving and transporting the cleaning agent. Several through holes are formed in the inner cylinder's sidewalls, designed to allow the dissolved cleaning agent solution to pass through while preventing incompletely dissolved solid particles from entering the connecting pipe. A connection port is located at the bottom of the inner cylinder, connected to one end of a connecting pipe via a threaded connection. The other end of the connecting pipe is connected to the connecting cylinder. The connecting cylinder connects to the connecting pipe, which quantitatively transports the dissolved cleaning agent solution to the external flushing system. A connecting plate is also installed at the bottom of the inner cylinder, with a spring mounted on it. Above the spring is a float made of lightweight, waterproof material, allowing it to move up and down with water level changes. When the water level rises, the float moves downwards under water pressure, compressing the spring and controlling the release of the cleaning agent solution; when the water level drops, the spring returns to its original position, pushing the float upwards and stopping the release of the cleaning agent solution.

[0009] Specifically, the placement chamber and the dissolving chamber are separated by a placement plate with several through holes. The through holes are designed to allow solid detergent to fall into the dissolving chamber slowly, preventing all detergent from entering at once and causing incomplete dissolution. Furthermore, the placement plate is secured to the inner wall of the placement chamber via a snap-fit ​​structure, facilitating regular cleaning or replacement by the user. A fixed cylinder within the dissolving chamber is threaded to the inner wall and has a flow guide channel that directs the dissolved detergent solution evenly towards the through holes in the inner cylinder, improving the flow efficiency of the detergent solution.

[0010] In the above technical solution, the working principle of the detergent metering device is as follows: S1, solid detergent is stored in the placement chamber and gradually falls into the dissolving chamber through the through holes on the placement plate; S2, the solid detergent entering the dissolving chamber comes into contact with the water flow and gradually dissolves; S3, the dissolved detergent solution flows into the connecting pipe through the through holes on the side wall of the inner cylinder; S4, the connecting pipe transports the detergent solution to the connecting cylinder and injects it meteredly into the external flushing system through the connecting pipe; S5, the float moves up and down with the water level, and the release amount of detergent solution is adjusted by the elastic force of the spring. The above steps achieve metered release of detergent through the linkage design of the mechanical structure, avoiding waste of detergent.

[0011] In the above technical solution, the present invention provides a detergent metering device, which has the following beneficial effects:

[0012] First, the float plate and spring work together to move up and down with the water level, while the spring's elasticity controls the release of detergent solution, ensuring an appropriate amount is used with each flush and preventing excessive or insufficient consumption. Second, the detergent gradually enters the dissolving chamber from the placement chamber, fully dissolves there, and then flows into the connecting pipe through the through-holes in the inner cylinder side wall, ensuring efficient and uniform dissolution. Third, the upper and lower sealing rings effectively prevent liquid leakage, ensuring the stability and reliability of the device. Furthermore, the observation window on the top cover allows users to monitor the detergent's storage and dissolution status in real time, facilitating timely replenishment. Finally, this device is suitable for various toilet tanks, effectively removing stubborn stains such as urine scale and grime, improving bathroom cleanliness and air quality.

[0013] In particular, the detergent dispensing device provided by this utility model solves the problems of untimely or wasteful detergent dissolution in existing technologies through reasonable structural design and functional configuration. Specifically, the layered design of the placement chamber and the dissolving chamber enables the solid detergent to fall gradually, avoiding the problem of insufficient dissolution caused by all the detergent entering the dissolving chamber at once; the design of the through holes on the side wall of the inner cylinder enables the filtration and transportation of the detergent solution; the cooperative design of the float and spring enables the quantitative release of the detergent solution; and the design of the upper and lower sealing rings improves the sealing performance of the device. The specific implementation of the above-mentioned innovations makes this utility model have significant technical progress and practicality.

[0014] In summary, this utility model, through its multi-layered structural design and mechanical linkage mechanism, achieves efficient dissolution and quantitative release of cleaning agents, solves the technical problems existing in the prior art, and possesses high application value and potential for technology promotion.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-5This utility model provides a detergent dispensing device, comprising an outer cylinder 1, a top cover 2, an observation window 3, a placement chamber 11, a dissolving chamber 12, an inner cylinder 5, a float 56, a spring 55, a connecting pipe 52, a connecting tube 61, and a connecting pipe 62, among other core components. These components work together to construct a complete system capable of storing, dissolving, and dispensing detergent in a measured manner. The outer cylinder 1, as the main outer shell of the device, is made of high-strength plastic or stainless steel, possessing corrosion resistance and durability, ensuring it is not easily damaged during long-term use. The interior of the outer cylinder 1 is divided into two main chambers by a partition structure: the upper placement chamber 11 and the lower dissolving chamber 12. The placement chamber 11 is used to store solid detergent, while the dissolving chamber 12 is used to receive the detergent gradually falling from the placement chamber 11 and complete its dissolution process.

[0025] Further reading Figure 2 The outer cylinder 1 has a top cover 2, which is fixed to the outer cylinder 1 by a threaded connection, allowing the user to easily open or close it to replenish the cleaning agent. A transparent observation window 3 is embedded in the center of the top cover 2, allowing the user to directly observe the remaining amount of cleaning agent in the placement chamber 11 and the dissolution status in the dissolving chamber 12. This design not only improves user convenience but also prevents insufficient cleaning agent from affecting normal use. Furthermore, the placement chamber 11 and the dissolving chamber 12 are separated by a placement plate 4, which has several through holes. The size of these through holes is precisely calculated to allow solid cleaning agent to slowly and gradually fall into the dissolving chamber 12. This design effectively prevents the cleaning agent from entering the dissolving chamber 12 all at once, resulting in incomplete dissolution. Simultaneously, the placement plate 4 is fixed to the inner wall of the placement chamber 11 by a snap-fit ​​structure, facilitating regular cleaning or replacement of the placement plate 4, thus ensuring the long-term stable operation of the device.

[0026] A fixed cylinder 13 is installed inside the dissolving chamber 12. An upper sealing ring 14 and a lower sealing ring 15 are respectively installed at the upper and lower ends of the fixed cylinder 13. The upper and lower sealing rings 14 and 15 are made of elastic materials such as silicone, providing good sealing performance and preventing the dissolved cleaning solution from leaking into the external environment. A flow guide groove is provided inside the fixed cylinder 13. The design of the flow guide groove helps to guide the dissolved cleaning solution to flow evenly towards the through-hole 51 of the inner cylinder 5, improving the flow efficiency of the cleaning solution. The inner cylinder 5 is located in the center of the dissolving chamber 12, and its sidewalls have multiple through-holes 51. The size of the through-holes 51 is optimized to allow the dissolved cleaning solution to pass through while preventing incompletely dissolved solid particles from entering the connecting pipe 52. A connection port 53 is provided at the bottom of the inner cylinder 5, which is connected to one end of the connecting pipe 52 via a threaded connection. The other end of the connecting pipe 52 is connected to the connecting cylinder 61. The connecting cylinder 61 is connected to the connecting pipe 62, which quantitatively delivers the dissolved cleaning solution to the external flushing system.

[0027] Specifically, a connecting plate 54 is installed at the bottom of the inner cylinder 5, and a spring 55 is mounted on the connecting plate 54. A float 56 is installed above the spring 55. The float 56 is made of a lightweight, waterproof material such as polypropylene, and can move up and down with the water flow as the water level changes. When the water level rises, the float 56 moves downward under water pressure, compressing the spring 55, thereby controlling the release of the detergent solution; when the water level drops, the spring 55 returns to its original position, pushing the float 56 upward, stopping the release of the detergent solution. This design achieves quantitative release of the detergent solution through a mechanical linkage mechanism, avoiding waste of detergent.

[0028] Combination Figure 3 and Figure 4 This allows for a clearer understanding of the specific working relationship between the float 56 and the spring 55. Under normal conditions, the float 56 is initially positioned at the bottom of the inner cylinder 5. As water flows into the dissolving chamber 12, the water level gradually rises, causing the float 56 to move downwards and compress the spring 55. The spring force of the spring 55 is precisely adjusted according to design parameters to ensure that the movement range of the float 56 is proportional to the water level change. When the water level reaches a certain height, the float 56 completely closes the through-hole 51 of the inner cylinder 5, stopping the release of the cleaning solution. When the water level drops, the spring 55 gradually returns to its original state, pushing the float 56 upwards and reopening the through-hole 51, allowing the cleaning solution to continue flowing into the connecting pipe 52.

[0029] Further reading Figure 5 The connection between the connecting pipe 52 and the connecting cylinder 61 uses a threaded interface design to ensure the sealing and stability of the connection. The connecting cylinder 61 has an internal flow control mechanism that controls the output of the cleaning solution by adjusting the opening and closing degree of the connecting pipe 62. The outlet end of the connecting pipe 62 is connected to the flushing system of the toilet tank, injecting a measured amount of dissolved cleaning solution into the flushing water, thereby achieving uniform mixing of the cleaning solution and water. This design not only ensures that the amount of cleaning solution used each time is appropriate, but also avoids excessive or insufficient consumption of cleaning solution.

[0030] The working principle of this utility model is as follows: S1. Solid detergent is stored in the placement chamber 11 and gradually falls into the dissolving chamber 12 through the through hole on the placement plate 4. S2. The solid detergent entering the dissolving chamber 12 comes into contact with the water flow and gradually dissolves. S3. The dissolved detergent solution flows into the connecting pipe 52 through the through hole 51 on the side wall of the inner cylinder 5. S4. The connecting pipe 52 transports the detergent solution to the connecting cylinder 61 and injects it quantitatively into the external flushing system through the connecting pipe 62. S5. The float 56 moves up and down with the water level, and the release amount of detergent solution is adjusted by the elasticity of the spring 55. The above steps realize the quantitative release of detergent through the linkage design of the mechanical structure, solving the problems of untimely dissolution or waste existing in the prior art.

[0031] The beneficial effects of this invention are reflected in several aspects: First, the coordinated design of the float 56 and spring 55 enables the quantitative release of the cleaning solution, ensuring that the amount of cleaning solution used each time is appropriate. Second, the cleaning solution gradually enters the dissolving chamber 12 from the placement chamber 11, and after being fully dissolved in the dissolving chamber 12, it flows into the connecting pipe 52 through the through hole 51 on the side wall of the inner cylinder 5, ensuring the dissolution efficiency and uniformity of the cleaning solution. Third, the design of the upper sealing ring 14 and the lower sealing ring 15 effectively prevents liquid leakage, ensuring the stability and reliability of the device. In addition, the observation window 3 on the top cover 2 allows users to monitor the storage and dissolution status of the cleaning solution in real time, facilitating timely replenishment. Finally, this device is suitable for various toilet tanks and can effectively remove stubborn stains such as urine scale and urine stains, improving the cleanliness of the bathroom and the air quality.

[0032] In summary, this invention, through its rational structural design and functional configuration, solves the problems of untimely or wasteful dissolution of detergents in existing technologies. The layered design of the placement chamber 11 and the dissolving chamber 12 allows for the gradual descent of solid detergent, preventing incomplete dissolution caused by all detergent entering the dissolving chamber 12 at once. The design of the through-hole 51 on the side wall of the inner cylinder 5 enables the filtration and delivery of the detergent solution. The coordinated design of the float 56 and spring 55 ensures the quantitative release of the detergent solution. The design of the upper sealing ring 14 and lower sealing ring 15 improves the sealing performance of the device. The specific implementation of these innovations makes this invention a significant technological advancement and practical application, widely applicable to toilet cleaning in homes and public places.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
