Description

Technical Field

[0001] This utility model belongs to the field of sustained-release devices, and specifically relates to an adjustable sustained-release device. Background Technology

[0002] In numerous fields such as agriculture, medicine, industry, and scientific research, effectively controlling the concentration and release rate of specific substances has become a key factor in ensuring product quality, improving production efficiency, and optimizing application effects. The precise regulation of substance release in different scenarios directly impacts the quality of the final outcome, and its importance is self-evident.

[0003] In agriculture, the supply of nutrients and the rational release of pesticides are the foundation for high-yield and high-quality crop production and pest and disease control. Taking slow-release pesticides as an example, if the pesticide is released too quickly, it may leave too much residue on the soil or crop surface, which not only wastes the pesticide but may also pollute the environment and increase the risk of pesticide residues in agricultural products. On the other hand, if the pesticide is released too slowly, it may not be able to control pests and diseases in a timely and effective manner, leading to reduced crop yields or even crop failure.

[0004] In industrial production and scientific research, the precise addition of chemical reagents is crucial for ensuring product quality and the stability of the production process.

[0005] Slow-release technology also plays a vital role in daily life. Taking drinking water purification technology as an example, supplementing trace elements is an important means of improving drinking water quality. However, the supplementation of trace elements requires precise control of their release rate and concentration to ensure that the trace element content in drinking water meets human health standards. If trace elements are released too quickly, the content in drinking water may instantly exceed the standard, and long-term consumption of such water can pose potential health hazards, such as metal poisoning. If trace elements are released too slowly, they cannot effectively improve the quality of drinking water and cannot meet people's needs for healthy drinking water. Furthermore, slow-release technology is widely used in releasing fragrances and air fresheners from the water outlet of showerheads and smart toilets. For example, in the field of smart toilets, a suitable release rate allows users to continuously experience a pleasant aroma during use, improving their quality of life. However, if the release rate is too fast, the fragrance will be too strong and pungent, affecting the user experience; if the release is too slow, it will fail to create a comfortable atmosphere.

[0006] Existing slow-release devices, such as the mineral slow-release filter element disclosed in publication number CN221644611U, have a fixed outlet diameter, which cannot adjust the slow-release rate of the substance according to actual production needs, and cannot meet the needs of different fields for precise control of the concentration and release rate of specific substances. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable sustained-release device to solve the problem that the sustained-release rate of existing sustained-release devices cannot be adjusted.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An adjustable slow-release device includes a reservoir and a sealing cap.

[0012] Furthermore, a filter screen is provided on one side of both the first and second water inlets, and the filter screen is installed at the bottom of the outer cylinder.

[0013] Furthermore, the slow-release hole is located in the area corresponding to the inner ring of the sealing cap, and the adjustment mechanism includes an adjustment plate, which is fixedly connected to the connecting rod. The adjustment holes are evenly arranged on the adjustment plate and correspond to the slow-release holes.

[0014] Furthermore, the slow-release hole is disposed on the side wall of the inner cylinder, and the adjustment mechanism includes an adjustment cylinder, the adjustment hole is fixedly connected to the connecting rod, the adjustment cylinder is a cylindrical structure with an open lower end, the adjustment hole is disposed on the side wall of the adjustment cylinder, and the adjustment hole corresponds to the slow-release hole.

[0015] Furthermore, the upper part of the regulating cylinder is provided with a dosing port, and a sealing cap is threaded onto the dosing port.

[0016] The beneficial effects of this utility model are:

By rotating the adjustment mechanism, the flow gap of the slow release hole is adjusted, thereby realizing stepless adjustment of the slow release rate of the substance.

[0018] 2) Several slots are provided on the inner wall of the outer cylinder, so that the connecting plate on the outer wall of the inner cylinder can be detachably inserted into the slots, which facilitates the separation of the inner cylinder and the outer cylinder, thereby facilitating the cleaning and maintenance of the outer cylinder and the inner cylinder; the connecting plate is locked with a locking nut to prevent the inner cylinder from being impacted and causing axial movement when the water flow pressure is high, thus ensuring the stability of the slow-release device.

[0019] 3) A filter screen is installed at the bottom of the outer cylinder to filter the liquid entering the slow-release device and prevent the first and second water inlets from becoming clogged.

[0020] 4) A dosing port is provided at the top of the regulating cylinder. When adding solid substances into the inner cylinder, the regulating hole can be inserted into the inner cylinder first, and then the slow-release substance can be added into the regulating cylinder through the dosing port. This avoids the phenomenon of jamming when installing the regulating cylinder after adding solid substances into the inner cylinder first. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0033] Example 1

[0034] like Figure 1 As shown, an adjustable slow-release device includes a reservoir 1 and a sealing cap 2, such as Figures 2-4 As shown, the storage container 1 includes an outer cylinder 11 and an inner cylinder 12. The inner cylinder 12 is connected to the inner wall of the outer cylinder 11 via a connecting plate 122. The bottom of the outer cylinder 11 is provided with a plurality of first water inlet holes 111, and the bottom of the inner cylinder 12 is provided with a plurality of second water inlet holes 121. Figure 5 As shown, the lower part of the encapsulation cover 2 is provided with an outer ring 22 and an inner ring 23, wherein the outer ring 22 is threadedly connected to the outer cylinder 11, and the inner ring 23 is threadedly connected to the inner cylinder 12. The area between the outer ring 22 and the inner ring 23 of the encapsulation cover 2 is provided with several water outlet holes 21; it also includes a slow release hole 24. The middle part of the encapsulation cover 2 is provided with a through hole 25, and a connecting rod 31 is provided inside the through hole 25. The lower part of the connecting rod 31 is provided with an adjustment mechanism, and the adjustment mechanism is provided with several adjustment holes 33 for adjusting the flow gap of the slow release hole 24. The upper part of the connecting rod 31 is threadedly connected with an adjustment nut 32.

[0035] like Figure 3 As shown, the inner wall of the outer cylinder 11 is provided with several slots 112, and the connecting plate 122 is detachably inserted into the slots 112, which facilitates the separation of the inner cylinder 12 and the outer cylinder 11, thereby facilitating the cleaning and maintenance of the outer cylinder 11 and the inner cylinder 12.

[0036] like Figure 3 , Figure 4As shown, a guide groove 113 is provided on one side of the slot 112, and a guide rod 123 is provided on one side of the connecting plate 122. The guide rod 123 is intermittently disposed in the guide groove 113, and a locking nut 124 is provided on one side of the guide rod 123 for locking the connecting plate 122 and the slot 112. This prevents the inner cylinder 12 from moving axially when the water pressure is high, thus ensuring the stability of the slow-release device.

[0037] As a preferred embodiment, a filter screen is provided on one side of the first water inlet hole 111 and the second water inlet hole 121. The filter screen is installed at the bottom of the outer cylinder 11 to filter the liquid entering the slow-release device and prevent the first water inlet hole 111 and the second water inlet hole 121 from becoming clogged.

[0038] like Figure 5 As shown, the slow-release hole 24 is disposed in the area corresponding to the inner ring 23 of the encapsulation cover 2, as... Figure 6 As shown, the adjustment mechanism includes an adjustment plate 3, which is fixedly connected to a connecting rod 31. Adjustment holes 33 are evenly arranged on the adjustment plate 3, and the adjustment holes 33 correspond to the slow-release holes 24. When the adjustment holes 33 on the adjustment plate 3 are fully aligned with the slow-release holes 24 on the sealing cover 2, the flow gap of the slow-release holes 24 is fully opened, and the slow-release speed is the fastest at this time. After rotating the connecting rod 31, the adjustment holes 33 and the slow-release holes 24 are gradually offset, so that the flow gap of the slow-release holes 24 gradually decreases until it is completely closed, thereby realizing stepless adjustment of the slow-release speed of a specific substance.

[0039] Example 2

[0040] Unlike Example 1, as Figures 7-9 As shown, the slow-release hole 24 is disposed on the side wall of the inner cylinder 12, as... Figure 9 As shown, the adjustment mechanism includes an adjustment cylinder 4, an adjustment hole 33 and a connecting rod 31 fixedly connected. The adjustment cylinder 4 is a cylindrical structure with an open lower end. The adjustment hole 33 is located on the side wall of the adjustment cylinder 4 and corresponds to the slow-release hole 24. When the adjustment hole 33 on the side wall of the adjustment cylinder 4 is fully aligned with the slow-release hole 24 on the side wall of the inner cylinder 12, the flow gap of the slow-release hole 24 is fully opened, and the slow-release speed is the fastest at this time. After rotating the connecting rod 31, the adjustment hole 33 on the adjustment cylinder 4 and the slow-release hole 24 on the side wall of the inner cylinder 12 are gradually misaligned, so that the flow gap of the slow-release hole 24 gradually decreases until it is completely closed, realizing stepless adjustment of the slow-release speed of a specific substance.

[0041] like Figure 9As shown, the upper part of the regulating cylinder 4 is provided with a dosing port, and a sealing cap 41 is threadedly connected to the dosing port. When a solid substance is added to the inner cylinder 12, the regulating hole 33 can be inserted into the inner cylinder 12 first, and then the slow-release substance can be added into the regulating cylinder 4 through the dosing port. This avoids the phenomenon of jamming when installing the regulating cylinder 4 after adding the solid substance to the inner cylinder 12 first.

[0042] In use, the slow-release substance is placed in the inner cylinder 12 of the storage container 1, and the sealing cap 2 is tightened. The slow-release device is placed inside the outer shell, and a water inlet pipe is set at one end of the outer shell and a water outlet pipe is set at the other end. When water flows into the outer shell from the water inlet pipe, the water flows into the slow-release device from the first water inlet hole 111 and the second water inlet hole 121. The water flowing in from the first water inlet hole 111 flows out from the water outlet hole 21, and the water flowing in from the second water inlet hole 121 impacts the slow-release substance and carries some of the slow-release substance out from the slow-release hole 24, thereby realizing the slow release of the specific substance.

[0043] When it is necessary to adjust the slow release rate of a substance, first loosen the adjusting nut 32, then rotate the adjusting mechanism to adjust the corresponding area of ​​the adjusting hole 33 and the slow release hole 24, thereby adjusting the flow gap of the slow release hole 24 and realizing stepless adjustment of the slow release rate of the substance.

[0044] When the slow-release device needs cleaning and maintenance, unscrew the sealing cap 2 and loosen the locking nut 124, then remove the inner cylinder 12 from inside the outer cylinder 11 to clean the outer cylinder 11, inner cylinder 12 and sealing cap 2 respectively.

[0045] The above content is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the utility model, they should all fall within the protection scope of this utility model.
