Description

Technical Field

[0001] This invention relates to the field of swimming pool cleaning technology, and in particular to a petal-opening and closing indicator for remaining medication dosage. Background Technology

[0002] In the field of pool cleaning, traditional methods typically involve directly adding disinfectant tablets to the pool to achieve sterilization and water quality maintenance. However, the dissolution rate of directly added tablets is affected by water flow, resulting in uneven release of the disinfectant. This uncontrollability complicates water quality management and makes it difficult to maintain a stable disinfection effect. In addition, disinfectant tablets usually sink directly to the bottom of the pool, making it difficult for users to observe the dissolution process with the naked eye. Furthermore, tablets that sink to the bottom of the pool cause the disinfectant to be released in a concentrated manner at the bottom, while the surface area is not sufficiently sterilized. This uneven distribution not only reduces the overall cleaning efficiency of the pool but may also cause localized corrosion problems on swimmers' skin, affecting the user experience and urgently requiring improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a drug dispenser that indicates the remaining amount of medicine by observing the opening and closing of the petals. It has the advantages of allowing users to understand the remaining amount of medicine by observing the unfolding state of the petals, having a controllable drug release rate, and being easy to operate.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a petal opening and closing indicator for the remaining amount of medicine, comprising a water inlet base, a medicine loading platform and several blades, wherein the water inlet base is provided with several water passage holes, the medicine loading platform is raised and lowered on the water inlet base, and the blades are tilted and connected to the water inlet base, so that the blades relative to the water inlet base can tilt and switch between an open state and a closed state.

[0005] The blade includes a first tilting part and a second tilting part located at both ends of the tilting center. The center of gravity of the blade is distributed on the second tilting part. When the loading platform is under load, the loading platform sinks relative to the water inlet base and presses against the first tilting part, while simultaneously driving the second tilting part to tilt relative to the water inlet base in the closing direction.

[0006] The water inlet base is rotatably provided with a flow regulating component for adjusting the flow rate of the water passage. The flow regulating component is anti-rotatingly connected to the loading platform, and the loading platform can slide up and down relative to the flow regulating component. The loading platform is provided with a screw tube, and the water inlet base is provided with a through hole corresponding to the screw tube. The screw tube is partially exposed through the through hole of the water inlet base.

[0007] The flow regulating component includes a rotating ring and a plurality of baffles connected to the circumference of the rotating ring. The rotating ring is rotatably connected to the water inlet base, and the rotating ring is anti-rotationally connected to the charging platform through an anti-rotation structure. Rotating the flow regulating component causes the baffles to cooperate with the corresponding number of water passage holes.

[0008] By adopting the above technical solution, in the initial state, since the center of gravity of the blade is distributed on the second tilting part, the second tilting part will sink relative to the first tilting part, so that the blade is in an unfolded state. When the tablet is placed on the loading platform, the weight of the tablet drives the loading platform to press down on the first tilting part of the blade, causing the second tilting part of the blade to tilt upward to a closed state. Then, the dosing device containing the tablet is placed on the water surface and floats. The weight of the dosing device itself causes the water passage to be submerged below the water surface. Water flows from the water passage into the water inlet base and comes into contact with the tablet to dissolve and form the drug. Then, the drug diffuses into the pool through the water passage, achieving the purpose of slow drug release. As the tablet gradually dissolves, the tablet mass decreases, and the downward pressure of the loading platform on the first tilting part gradually decreases, causing the second tilting part to slowly descend relative to the first tilting part. At the same time, under the action of buoyancy, the loading platform gradually rises relative to the water inlet base. When the tablet is completely dissolved... During dispensing, the second tilting section descends to its lowest position, causing the blades to move relative to the inlet base to the unfolded state. Users can observe the unfolded state of the blades to determine whether the tablets have completely dissolved, allowing for tablet replacement or tablet retrieval. Additionally, users can rotate the screw-on tube to rotate the dispensing platform, which in turn rotates the baffle plate via the rotating ring. This baffle plate blocks a corresponding number of water passages, ensuring water flow only through the unblocked passages between the inlet base and the pool. This regulates the flow rate through the passages, thereby controlling the dosage of medication released into the pool per unit time. The operation is convenient, and the guide mechanism between the screw-on tube and the through-hole improves the consistency of the dispensing platform's lifting direction within the inlet base, effectively reducing the chance of jamming during lifting. This system allows users to observe the unfolded state of the blades to understand the remaining amount of medication, provides controllable medication release speed, and offers convenient operation.

[0009] A further feature of the present invention is that: the side wall of the water inlet base is provided with a through mounting hole; the first tilting part and the second tilting part are connected by a tilting connecting part; the tilting connecting part is movably inserted into the mounting hole; the first tilting part and the second tilting part form anti-detachment steps at both ends of the tilting connecting part; the first tilting part and the second tilting part constrain the tilting connecting part into the mounting hole by corresponding to the anti-detachment steps; and the tilting connecting part avoids and cooperates with the mounting hole on the tilting trajectory of the blade.

[0010] By adopting the above technical solution, the blade can be tilted relative to the water inlet base with the tilting connection as the tilting center, and the first tilting part and the second tilting part can cooperate with the mounting hole, which can effectively prevent the blade from coming out of the mounting hole during the tilting process.

[0011] A further configuration of the present invention is as follows: the anti-rotation structure includes an interference portion and a sliding portion; a plurality of interference portions are arranged circumferentially on the flow regulating member and extend axially along the rotating ring; a plurality of sliding portions are arranged circumferentially on the loading platform and extend radially along the loading platform; the interference portion and the sliding portion are anti-rotationally engaged; a lifting groove is formed between adjacent interference portions; and the sliding portion slides and moves relative to the flow regulating member through the lifting groove.

[0012] By adopting the above technical solution, when the screw-in tube drives the loading platform to rotate, the anti-rotation effect of the sliding part and the interference part is used to drive the flow regulating component to rotate synchronously, thereby adjusting the effective water blocking area of ​​the baffle plate and the water passage hole. At the same time, the lifting groove between adjacent interference parts can limit and guide the lifting direction of the sliding part, so that the axial lifting direction of the loading platform relative to the flow regulating component is more consistent.

[0013] A further feature of the present invention is that: the inner wall of the water inlet base is provided with a plurality of limiting ribs at circumferential intervals, the baffle plate cooperates with the limiting ribs to stop and constrain the rotation angle of the flow regulating member relative to the water inlet base, a plurality of water passage holes are provided between adjacent limiting ribs, and the number of the plurality of water passage holes gradually increases from one side baffle plate to the adjacent other side baffle plate.

[0014] By adopting the above technical solution and adding the limiting rib, the rotation angle of the flow regulating component can be limited, so that the user can clearly understand the rotation position of the flow regulating component, thereby improving the control effect of the flow regulation of the water passage.

[0015] A further feature of the present invention is that the blade is provided with a plurality of protrusions that avoid the water passage holes, and when the blade is tilted relative to the water inlet base to a closed state, the blade and the water inlet base are engaged through the gap of the protrusions.

[0016] By adopting the above technical solution, the addition of protrusions can prevent the blades from being overly fitted to the water inlet base when the blades are closed, which could lead to blockage of the water passage.

[0017] A further feature of the present invention is that the screw-in tube is connected to the center bottom of the loading platform, the screw-in tube has a downward-opening hollow cavity, and the outer wall of the screw-in tube is provided with a plurality of ribs protruding along the axial direction, and the screw-in tube slides and engages with the through hole through the ribs.

[0018] By adopting the above technical solution, the hollow cavity can reduce the overall weight of the screw tube, while saving raw materials and reducing production costs. The addition of ribs can reduce the contact area between the screw tube and the water inlet base, thereby reducing friction and improving the smoothness of the screw tube's sliding relative to the water inlet base.

[0019] A further feature of the present invention is that the bottom of the water inlet base is sunken to form a support platform, the bottom of the support platform is a plane, and a plurality of mounting holes are spaced apart circumferentially on the side wall of the support platform.

[0020] By adopting the above technical solution, the bottom plane of the dispensing device can be used to place the dispensing device stably on the platform, which facilitates the placement of the tablets.

[0021] A further feature of the present invention is that: a pressing ring is provided on the lower surface of the loading platform, and the loading platform is pressed and engaged with the first tilting part through the pressing ring; a support ring is provided on the support platform, and when the blade is in a closed state relative to the water inlet base, the water inlet base is supported and engaged with the first tilting part through the support ring.

[0022] By adopting the above technical solution, the charging station can simultaneously press the first tilting part of multiple blades using the pressing ring, and the support ring can simultaneously support and position the first tilting part of multiple blades. By utilizing the synergistic effect of the pressing ring and the support ring, the tilting angle of each blade can be kept consistent.

[0023] A further feature of the present invention is that an upper housing is detachably mounted on the water inlet base, a dosing channel is axially opened in the middle of the upper housing, and a dosing cover is detachably mounted on the top of the upper housing.

[0024] By adopting the above technical solution, users can remove the dosing cap from the upper shell, then deliver the tablets to the dosing platform through the dosing channel. After dosing, the dosing cap is then placed back on the upper shell to prevent excessive water surface movement from causing the tablets to jump out of the dosing channel.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. Several blades are connected to the water inlet base by tilting. At the same time, a loading platform is raised and lowered in the loading platform. The loading platform and the first tilting part of the blades are pressed together, and the center of gravity of the blades is distributed on the second tilting part. As the tablet gradually dissolves, the downward pressure of the loading platform on the first tilting part gradually decreases, so that the second tilting part slowly descends relative to the first tilting part. When the tablet is completely dissolved, the second tilting part descends to the lowest position, so that the blades move to the unfolded state relative to the water inlet base. The user can judge whether the tablet has completely dissolved by observing the unfolded state of the blades of the dosing device, so as to replace the tablet or retrieve the dosing device.

[0027] 2. A flow regulator is rotatably installed inside the water inlet base. The interference part of the flow regulator is connected to the sliding part of the charging platform to prevent rotation. The sliding part of the charging platform can slide up and down in the sliding groove between adjacent interference parts. The user can rotate the screw tube to drive the charging platform to rotate. The charging platform then drives the baffle plate to rotate through the rotating ring, so that the baffle plate blocks the corresponding number of water passages. The water flow can only flow between the water inlet base and the pool through the unblocked water passages, thereby adjusting the release rate of the agent from the dosing device.

[0039] The invention will now be further described with reference to the accompanying drawings.

[0040] A dispensing device that indicates the remaining dosage by the opening and closing of flower petals, such as Figures 1-3 , Figure 7 and Figure 9As shown, the device includes a water inlet base 1, a loading platform 2, and several blades 3. The water inlet base 1 has several water passage holes 11. The loading platform 2 is elliptical and mounted on the water inlet base 1. The blades 3 are pivotally connected to the water inlet base 1, allowing the blades 3 to pivot between an extended and a closed state relative to the water inlet base 1. Each blade 3 includes a first pivoting part 31 and a second pivoting part 32 located at opposite ends of the pivoting center. The volume of the second pivoting part 32 is larger than that of the first pivoting part 31, causing the center of gravity of the blades 3 to be distributed on the second pivoting part 32. When the loading platform 2 is under load, it sinks relative to the water inlet base 1 and presses against the first pivoting part 31, while simultaneously driving the second pivoting part 32 to pivot relative to the water inlet base 1 in a closing direction. A flow regulating component 4 is rotatably mounted inside the water inlet base 1 to adjust the flow rate of the water passage holes 11. The flow regulating component 4 is anti-rotationally connected to the loading platform 2, and the loading platform 2 can slide up and down relative to the flow regulating component 4. The loading platform 2 is equipped with a screw-on tube 21, and the water inlet base 1 has a through hole 12 corresponding to the screw-on tube 21. The lower part of the screw-on tube 21 is exposed to the water inlet base 1 through the through hole 12. In this embodiment, the inner wall of the water inlet base 1 is a spherical structure, which allows the water inlet base 1 to float on the water surface. Some parts of the dosing device can be made of foam or lightweight plastic to provide sufficient buoyancy for the dosing device in the water. The water passage hole 11 is opened along the axial direction of the water inlet base 1, so that the extension direction of the water passage hole 11 is parallel to the opening direction of the through hole 12. This design can effectively prevent the incoming water flow from directly impacting the surface of the tablet 7, avoiding the tablet from dissolving too quickly in some areas, thereby ensuring the slow-release effect of the drug. In this embodiment, the blade 3 includes large blades and small blades. The large blades and small blades are arranged alternately along the circumference of the water inlet base 1, and multiple large blades form an outer blade group, and multiple small blades form an inner blade group.

[0041] like Figures 2-3 and Figures 5-10As shown, a mounting hole 13 is provided through the side wall of the water inlet base 1. The first tilting part 31 and the second tilting part 32 are connected by a tilting connecting part 33, which is movably inserted into the mounting hole 13. The first tilting part 31 and the second tilting part 32 have anti-detachment steps 30 at both ends of the tilting connecting part 33. The first tilting part 31 and the second tilting part 32 constrain the tilting connecting part 33 into the mounting hole 13 through the corresponding anti-detachment steps 30. The tilting connecting part 33 avoids and cooperates with the mounting hole 13 on the tilting trajectory of the blade 3. In this embodiment, the first tilting part 31 and the water inlet base 1 are connected by a tilting connecting part 33. There are movable gaps between the inner walls of the water base 1 and between the second tilting part 32 and the outer wall of the water inlet base 1. The thickness of the tilting connection part 33 is less than the opening height of the mounting hole 13, so that the tilting connection part 33 avoids the mounting hole 13 on the tilting trajectory of the blade 3. This allows the blade 3 to tilt relative to the water inlet base 1 with the bottom support point of the tilting connection part 33 as the tilting center. The first tilting part 31 and the second tilting part 32 can cooperate with the mounting hole 13, which can effectively prevent the blade 3 from coming out of the mounting hole 13 during the tilting process. The blade 3 is made of tough plastic. In this embodiment, the tough plastic can be made of nylon, polyethylene, polypropylene, or polycarbonate. The first tilting part 31 has guide slopes 311 on both sides. The first tilting part 31 is guided into the mounting hole 13 via the guide slopes 311 for assembly. The flow regulating component 4 includes a rotating ring 41 and several baffles 42 connected circumferentially to the rotating ring 41. The rotating ring 41 is rotatably connected to the water inlet base 1, and the rotating ring 41 is anti-rotated by an anti-rotation structure to the charging platform 2. Rotating the flow regulating component 4 causes the baffles 42 to engage with the corresponding number of water passage holes 11, allowing the user to... The loading platform 2 can be rotated by rotating the screw tube 21. The loading platform 2 then drives the baffle plate 42 to rotate through the rotating ring 41, so that the baffle plate 42 blocks the corresponding number of water passage holes 11. The water flow can only flow between the water inlet base 1 and the pool through the unblocked water passage holes 11, thereby adjusting the release speed of the medicine from the dosing device. In other embodiments, rotating shafts can be set on both sides of the blade 3 and rotatedly connected to the water inlet base 1. In this embodiment, a reinforcing rib 40 is connected between the baffle plate 42 and the rotating ring 41. The reinforcing rib 40 can improve the connection strength between the baffle plate 42 and the rotating ring 41.

[0042] like Figure 3 , Figures 6-8 and Figure 10As shown, the anti-rotation structure includes an interference section 43 and a sliding section 22. Several interference sections 43 are circumferentially spaced on the flow regulating member 4, and extend axially along the rotating ring 41. Several sliding sections 22 are circumferentially spaced on the loading platform 2, and extend radially along the loading platform 2. The interference sections 43 and sliding sections 22 engage in an anti-rotation cooperation. A lifting groove 431 is formed between adjacent interference sections 43. The sliding section 22 slides and moves relative to the flow regulating member 4 through the lifting groove 431. The screw-in tube 2... When the loading platform 2 is driven to rotate, the anti-rotation action of the sliding part 22 and the interference part 43 drives the flow regulating component 4 to rotate synchronously, thereby adjusting the effective water blocking area of ​​the baffle plate 42 and the water passage hole 11. At the same time, the lifting groove 431 between adjacent interference parts 43 can limit and guide the lifting direction of the sliding part 22, making the axial lifting direction of the loading platform 2 relative to the flow regulating component 4 more consistent. The inner wall of the water inlet base 1 is provided with several limiting ribs 14 at intervals along the circumference. The baffle plate 42 and the limiting ribs 14 stop and cooperate to constrain the rotation angle of the flow regulating component 4 relative to the water inlet base 1. Several water passage holes 11 are opened between adjacent limiting ribs 14, and the number of water passage holes 11 gradually increases from one side of the baffle plate 42 to the adjacent side of the baffle plate 42. The addition of the limiting ribs 14 can limit the rotation angle of the flow regulating component 4, so that the user can clearly understand the rotation position of the flow regulating component 4, thereby improving the control effect of the flow regulation of the water passage hole 11. In the example, there are six limiting ribs 14, so that the rotation angle of the flow regulating component 4 relative to the water inlet base 1 is controlled within 60°. There are four rows of water passage holes between adjacent limiting ribs 14, and the number of water passage holes 11 in each row of water passage holes increases by one from one limiting rib 14 to the other limiting rib 14. In other embodiments, the water passage holes 11 can also be opened along the circumference of the water inlet base 1, and the water passage cross-sectional area of ​​the water passage holes 11 gradually increases or decreases from one limiting rib 14 to the other limiting rib 14.

[0043] like Figures 2-8 and Figure 10As shown, the bottom of the water inlet base 1 is recessed to form a support platform 15. The bottom of the support platform 15 is set as a plane, and several mounting holes 13 are opened circumferentially on the side wall of the support platform 15. The bottom plane of the dosing device can be used to place the dosing device stably on the platform, which is convenient for placing the tablets 7. The lower surface of the dosing platform 2 is provided with a pressing ring 23 protruding downward. The dosing platform 2 is pressed and engaged with the first tilting part 31 through the pressing ring 23. The support platform 15 is provided with a support ring 151 protruding on the support platform 15. When the blades 3 are in the closed state relative to the water inlet base 1, the water inlet base 1 is supported and engaged with the first tilting part 31 through the support ring 151. The dosing platform 2 can press the first tilting part 31 of multiple blades 3 at the same time using the pressing ring 23. In addition, the support ring 151 can support and position the first tilting part 31 of multiple blades 3 at the same time. With the synergistic effect of the pressing ring 23 and the support ring 151, the tilting angle of each blade 3 can be kept consistent.

[0044] like Figures 7-8 and Figure 10 As shown, the blade 3 is provided with several protrusions 321 that avoid the water passage hole 11. When the blade 3 is tilted relative to the water inlet base 1 to the closed state, the blade 3 and the water inlet base 1 are fitted with a gap through the protrusions 321. The addition of the protrusions 321 can prevent the blade 3 from being overly fitted with the water inlet base 1 in the closed state, which would cause the water passage hole 11 to be blocked. The screw tube 21 is connected to the center bottom of the loading platform 2. The screw tube 21 has a hollow cavity 211 with a downward opening, and several ribs 212 are axially protruding on the outer wall of the screw tube 21. The screw tube 21 slides with the through hole 12 through the ribs 212. The hollow cavity 211 can reduce the overall weight of the screw tube 21. The addition of the rib 212 reduces the contact area between the screw tube 21 and the water inlet base 1, thereby improving the smoothness of the sliding of the screw tube 21 relative to the water inlet base 1 by reducing friction. The upper shell 5 is detachably installed on the water inlet base 1 by means of a snap-fit ​​structure. The middle of the upper shell 5 is axially provided with a dosing channel 51. A dosing cover 6 is detachably installed on the upper shell 5. The user can remove the dosing cover 6 from the upper shell 5 and then deliver the tablet 7 to the dosing platform 2 through the dosing channel 51. After the dosing is completed, the dosing cover 6 is put back on the upper shell 5 to prevent the tablet 7 from jumping out of the dosing channel 51 due to excessive water surface sway.

[0045] The basic working principle of this invention is as follows: In the initial state, since the center of gravity of the blade 3 is distributed on the second tilting part 32, the second tilting part 32 will sink relative to the first tilting part 31, so that the blade 3 is in an unfolded state. When the tablet 7 is placed on the loading platform 2, the gravity of the tablet 7 drives the loading platform 2 to press down the first tilting part 31 of the blade 3, so that the second tilting part 32 of the blade 3 tilts upward to a closed state. Then, the dosing device containing the tablet 7 is placed on the water surface to float, and the dosing device itself is used to make the blade 3 open. The water passage 11 is submerged below the water surface. Water flows into the inlet base 1 through the water passage 11 and dissolves in contact with the tablet 7 to form a drug. The drug then diffuses into the pool through the water passage 11, achieving the purpose of slow drug release. As the tablet 7 gradually dissolves, its mass decreases, and the downward pressure of the loading platform 2 on the first tilting part 31 gradually decreases, causing the second tilting part 32 to slowly descend relative to the first tilting part 31. At the same time, under the action of buoyancy, the loading platform 2 is driven to gradually rise relative to the inlet base 1. When the tablet... When the tablet 7 is completely dissolved, the second tilting part 32 descends to its lowest position, causing the blade 3 to move relative to the water inlet base 1 to the unfolded state. The user can observe the unfolded state of the dosing device blade 3 to determine whether the tablet 7 is completely dissolved, and thus replace the tablet 7 or retrieve the dosing device. In addition, the user can rotate the screw tube 21 to drive the loading platform 2 to rotate. The loading platform 2 then drives the baffle plate 42 to rotate through the rotating ring 41, so that the baffle plate 42 blocks the corresponding number of water passage holes 11. The water flow can only flow between the water inlet base 1 and the pool through the unblocked water passage holes 11, thereby adjusting the water flow rate of the water passage holes 11 and controlling the dosage of medicine released into the pool by the dosing device per unit time. The operation is convenient, and the guiding cooperation between the screw tube 21 and the through hole 12 can improve the consistency of the lifting direction of the loading platform 2 in the water inlet base 1, effectively reducing the probability of jamming when the loading platform 2 is lifted. It has the advantages of allowing the user to understand the residual amount of tablet by observing the unfolded state of the blade, controllable drug release speed, and convenient operation.
