Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning appliances, and particularly relates to an adjustable release device for toilet cleaners. Background Art

[0002] With the improvement of sanitation conditions, flush toilets have been widely popularized in urban and rural areas, greatly facilitating people's lives. However, the daily maintenance and cleaning work of toilets is rather cumbersome. At present, some toilet cleaners, such as toilet bowl cleaners, have emerged on the market, which have alleviated the toilet cleaning problem to a certain extent. However, most of such cleaners in the prior art need to be manually applied to the dirt on the toilet, and after decomposition for a period of time, they are then scrubbed with a toilet brush. The operation process is complex. There is also a toilet cleaning block product that is placed in the water tank and relies on its own dissolution to achieve cleaning. However, due to different usage frequencies, its release concentration is difficult to stably control. The concentration of the cleaner released after a long period of non-use is too high, and the concentration is too low when used frequently. Moreover, after using for a period of time, the amount of cleaner discharged each time during drainage gradually decreases, and the concentration of the cleaner in the aqueous solution continues to decrease, significantly weakening the decontamination effect. Later, a patent (Patent No.: 2016105351732) disclosed a technical solution for an adjustable release device for toilet cleaners, which achieved the effect of sending a fixed amount of cleaner into the water tank through a control structure in which a diversion port is provided at the bottom of the tank body and is connected to a one-way valve to control the addition of the cleaner into the toilet. However, this technology has deficiencies in the adjustment of the cleaner output amount. For example, the amount of cleaner output cannot be adjusted. Each time, only a fixed amount of cleaner can be released, and only a fixed concentration of solution can be produced. Stubborn stains on the toilet cannot be quickly removed with a high-concentration solution. Summary of the Invention

[0003] The present invention aims to provide an adjustable release device for toilet cleaners, which, by means of the water inlet and outlet mechanism of the toilet water tank, sends the cleaner with the output amount adjusted by the user into the toilet water tank, and adds new cleaner every time water enters, ensuring that an aqueous solution with the concentration required by the user within the control range of this mechanism is produced, and cleaning the toilet with the discharged water, achieving a better cleaning effect.

[0004] To achieve the above object, the present invention adopts the following technical solutions: An adjustable release device for toilet cleaners includes a cleaner storage tank body (1) that is matched with the toilet. The tank body (1) is connected to the cylinder body (2) in a threaded manner through an extension piece. A diversion port (3) is provided on the cylinder body (2), and the diversion port (3) is connected to a control mechanism for controlling the addition of the cleaner into the toilet. The control mechanism includes the cylinder body (2), a piston (4), the piston limit retaining ring (8), a baffle (13), a gravity delay body (12) connected to the piston (4) through the baffle (13), and a sector motion limit plate (11). The gravity delay body (12) provides power for the operation of the control mechanism.

[0005] As a preferred solution, the piston includes a plurality (≥3) of discs (6) integrally formed with the piston rod and having the same material and specifications. The discs are spaced along the axial direction of the piston rod, and the distance between adjacent discs is the same and greater than or equal to 5 mm. Each disc has a groove on its outer peripheral surface, and the groove is adapted to install a sealing ring of the same specification. The sealing function is achieved by the tight fit between the sealing ring and the inner wall of the external cylinder; each disc, the sealing ring and the inner wall of the cylinder form a cleaning agent transfer space (9) with the same size and purpose, enabling the cleaning agent to be directionally transported within this space as the piston moves, so as to achieve the cleaning agent release function; the discs are all coaxial with the piston rod, effectively reducing the friction increased due to eccentric movement of the piston, thereby reducing the sway amplitude during piston movement, further improving the tightness of the fit between the sealing ring and the inner wall of the cylinder, and enhancing the sealing stability;

[0006] As a preferred solution, the limiting snap ring device is used to limit the downward axial displacement of the piston in the cylinder. The ring is of a split structure and is composed of two semi-circular members, which are detachably assembled through a complementary pin-socket matching structure. When the two semi-circular members are fitted with each other through the pin-socket structure, a complete annular limiting member can be formed, and its outer diameter is larger than the inner wall diameter of the cylinder, so as to form a blocking structure at the top of the cylinder to prevent the piston from moving downward in the cylinder; further, each semi-circular member of the snap ring is provided with a semi-circular notch in the middle, and the two semi-circular notches are combined to form an annular bayonet adapted to the outer diameter of the piston rod. When the ring is installed on the piston assembly, the annular bayonet can be tightly sleeved on the outer periphery of the piston rod between each disc of the piston, so that the ring and the piston assembly form a stable circumferential positioning relationship, thereby ensuring that during the process of restricting the downward movement of the piston, the snap ring always maintains a stable limiting state and avoids axial movement.

[0007] As a preferred solution, the gravity delay body is an inverted straight-wall cup-shaped floating body.

[0008] As a preferred solution, a baffle integrally formed with the gravity delay body is circumferentially arranged along the top surface of the gravity delay body, and the length of the baffle is greater than one-half (excluding one-half) of the circumference of the gravity delay body.

[0009] The piston rod is connected to both ends of the baffle through a cross bar (10) integrally formed with and perpendicular to it. The two ends of the cross bar pass through the baffle in a penetrating manner, and the diameter of the rod body part penetrating the baffle is smaller than the diameter of the remaining non-penetrating part of the cross bar. After the cross bar passes through the baffle, the step structure formed by the diameter difference abuts against the inner surface of the baffle to realize the fixed connection between the cross bar and the baffle. Based on the geometric center of the top surface of the delay body, the main part of the baffle is located on one side of the geometric center point, while the piston rod and the cross bar as a whole are on the other side of the geometric center point.

[0010] As an optimal solution, the length of the baffle of the gravity delay body is greater than half of the perimeter of its top surface (regular open shape). The two ends of the baffle are respectively connected through the two ends of the cross bar connected to the piston rod. When the water in the water tank is drained and the gravity delay body loses buoyancy, the cross bar (10) will apply an upward support reaction force to the gravity delay body. Since the main body area of the cross bar and the baffle of the gravity delay body are arranged relatively with the geometric center of the top surface of the gravity delay body as the symmetry reference, one side of the top surface of the gravity delay body surrounded by the baffle has a greater weight than the other side not covered by the baffle. Driven by the gravity, the side of the top surface of the gravity delay body surrounded by the baffle tilts downward with the cross bar (10) as the rotation axis. Then, a temporary cleaning agent storage space is constructed between the baffle and the top surface of the gravity delay body. This space can realize the temporary storage function of the cleaning agent, creating a necessary condition for accurately and quantitatively adding the cleaning agent to the water tank later, and effectively ensuring the accuracy and stability of the cleaning agent addition during the operation of the mechanism; Further, since the main body area of the cross bar and the baffle of the gravity delay body are arranged relatively with the geometric center of the top surface of the gravity delay body as the symmetry reference, the top surface area of the side of the top surface of the gravity delay body surrounded by the baffle > the top surface area of the other side not covered by the baffle. When the gravity delay body loses buoyancy, it is in an eccentric hanging state, with the cross bar (10) set away from the geometric center of the top surface as the hanging point. When the water level rises, the gravity delay body is affected by the buoyancy force. According to Archimedes' principle, due to the eccentric layout of the hanging point, the volumes of the two sides (the two sides that form the complete structure of the gravity delay body) of the gravity delay body immersed in the liquid are different. The side away from the hanging point has a larger volume of displaced liquid and thus a relatively stronger buoyancy force. Under the action of the buoyancy difference, the upward lifting amplitude of this side is greater, resulting in the side of the gravity delay body away from the hanging point being higher than the side close to the hanging point, forming an inclined state until the top surface of the gravity delay body contacts the sector-shaped movement limit plate, keeping the gravity delay body inclined within the limit range of the sector-shaped movement limit plate.

[0011] As an optimized solution, the limiting plate of the gravity delay body is arranged orthogonally to the piston rod along the length direction, and this limiting plate is also orthogonal to the cross bar connecting the piston rod and the upper baffle of the gravity delay body, constructing a regular spatial positioning structure. The limiting plate and the piston rod are processed by an integral molding process to form an inseparable rigid connection body. By eliminating the assembly gap and optimizing the stress distribution, the connection strength between components is significantly enhanced, effectively improving the mechanical stability and fatigue resistance of the overall structure. At the design level of dimensional parameters, strict limitations are imposed on the length of the limiting plate: its extended length does not exceed the plane where the top surface of the gravity delay body is located, or is completely within the spatial area defined by the baffle integrally formed with the gravity delay body. Based on this precise dimensional constraint and spatial positioning mechanism, during the operation of the cleaning mechanism, the limiting plate can accurately guide and limit the gravity delay body, ensuring that the gravity delay body makes a rotational motion along a fan-shaped trajectory around a fixed point along a predetermined trajectory, effectively avoiding operation failures such as mechanism jamming and component interference caused by displacement deviation, thereby greatly improving the stability, reliability, and motion control accuracy of the cleaning mechanism operation, and ensuring the long-term stable operation of the equipment.

[0012] By implementing the above technical solutions, the present invention has the following beneficial effects: 1. Quantitative release technology based on dynamic water level changes: The present invention triggers the built-in detergent quantitative release mechanism to perform a release operation with a preset output by sensing the liquid level change during the water level drop in the toilet tank. When the tank enters the water injection stage and the water level rises, the released detergent and the injected water flow are quickly and fully fused within a single water injection cycle to form a cleaning solution with a stable concentration. This technical solution effectively avoids the problems of dilution of the cleaning solution concentration and reduction of cleaning efficiency caused by frequent flushing in the traditional cleaning mode. Compared with the situation where conventional detergents need multiple flushing cycles or long-term standing to reach an effective cleaning concentration, the present invention significantly shortens the time required to prepare the cleaning solution through an innovative water level sensing trigger mechanism, greatly improving the cleaning efficiency and the reliability of the cleaning effect. 2. Dynamic anti-dissolution consumption control mechanism: The present invention effectively avoids the technical problems of abnormal cumulative increase in solution concentration and premature depletion of the detergent caused by continuous dissolution of the detergent in the water body in the tank under the condition that the toilet has been standing without flushing for a long time through an innovative dynamic anti-dissolution consumption control mechanism. The device regulates the contact state between the detergent and the water body based on the liquid level change, automatically blocking the dissolution process during the tank standing period to avoid shortening the service life of the detergent due to unnecessary dissolution. Compared with the traditional cleaning solution, the present invention significantly improves the utilization efficiency of the detergent, reduces the consumable material loss within a single cleaning cycle, realizes effective control of the cleaning cost, and has significant economic advantages and market application value. 3. Adjustable detergent release: Users can preset the detergent release amount based on the pollution degree of stains on the inner wall of the toilet (such as slight adhesion, moderate deposition, severe solidification, etc.), enabling quantitative control of the detergent output. It can effectively adapt to diverse cleaning scenarios from daily maintenance cleaning to deep scale removal, efficiently meet the differentiated cleaning needs of users, and significantly improve cleaning efficiency and pertinence. Brief Description of the Drawings

[0013] Attached to the specification Figure 1 It is a schematic structural diagram of an embodiment of the present invention. Detailed Description of the Specific Embodiment

[0014] The following will further elaborate on the present invention in conjunction with specific embodiments.

[0015] Embodiment 1: The adjustable release device for toilet cleaner, as attached to the specification Figure 1 As shown, it includes a tank body (1) for containing detergent, which is used in cooperation with the toilet and is fixed in the toilet water tank by a hanging method. The tank body (1) is connected to the cylinder body (2) in a threaded manner through an extension piece. A diversion port (3) is provided on the cylinder body, and the diversion port (3) communicates with the bottom of the cylinder body (2) through a transfer space (9) between a piston (4) and a disc with a sealing ring (7) [the number of this disc (6) is greater than or equal to ≥ 3]. The piston rod (5) is connected to a baffle (13) through a cross bar (10). The baffle (13) is integrally formed with a gravity delay body (12), and the gravity delay body (12) is an inverted straight-wall cup-shaped floating body.

[0016] Working principle of the present invention: A relatively large amount of detergent can be loaded into the tank body (1) at one time. When the toilet flushing button is pressed, the water level in the water tank drops rapidly, causing the gravity delay body (12) to lose buoyancy. The gravity delay body (12) pulls the piston (4) to move slowly downward by its own gravity. Whenever the transfer space (9) communicates with the diversion port (3), the detergent will fill the transfer space (9) through the diversion port (3), and the transfer space (9) will transport the detergent out of the bottom of the cylinder body (2) to achieve the purpose of releasing the detergent until the limit retaining ring (8) contacts the top of the cylinder body (2), and the piston (4) and the gravity delay body (12) stop moving downward, and the control structure stops releasing the detergent. The gravity delay body (12) loses buoyancy, and the side of the top surface of the gravity delay body (12) surrounded by the baffle (13) tilts downward with the cross bar (10) as the rotation axis. The sector-shaped movement limiting plate (11) limits the movement range of the gravity delay body (12), and thus a temporary detergent storage space is constructed between the baffle and the top surface of the gravity delay body. After the water level rises, the detergent and water start to mix, and the gravity delay body (12) floats up and pushes the piston (4) to rise, making the control structure reach the initial state of releasing the detergent and waiting for the next flushing of the toilet water tank.
