[0030] Embodiment one, Figures 1 to 5 A schematic structural diagram of a slow-release device for use in a liquid according to the present embodiment comprises a container shell 1, an end cap 2, and a weight block 3. The upper end of the container shell 1 is provided with a port 4, and the interior of the container shell 1 is hollow. The end cap 2 is sealingly arranged on the port 4. A tapered through-hole 5 is formed in the middle of the end cap 2. The weight block 3 is arranged on the inner side wall of the end cap 2. An avoiding through-hole 6 is formed in the middle of the weight block 3. The avoiding through-hole 6 corresponds to the tapered through-hole 5. The tapered through-hole 5 is used to slowly release the substance contained in the interior of the container shell 1 to the outside of the end cap 2.
[0031] The inner end of the end cap 2 is provided with a groove 7. The port 4 is provided with a boss 8. The end cap 2 is connected to the port 4 by embedding the groove 7 and the boss 8 in each other. The end cap 2 and the container shell 1 are connected by ultrasonic welding or screw threads.
[0032] The end cap 2 is sealingly arranged on the port 4 of the container shell 1 by embedding the groove 7 and the boss 8 in each other. The gap between the end cap 2 and the container shell 1 is connected by ultrasonic welding or screw threads, thereby improving the sealing performance of the connection between the end cap 2 and the container shell 1.
[0033] The diameter of the tapered through-hole 5 gradually decreases from the inner side wall to the outer side wall of the end cap 2.
[0034] The diameter of the opening of the tapered through-hole 5 at the outer side wall of the end cap 2 is D, and 0.31 mm≤D≤5.0 mm. The height of the opening of the tapered through-hole 5 at the outer side wall of the end cap 2 is higher than the height of the outer side wall surface of the end cap 2.
[0035] In the present embodiment, the diameter D of the tapered through-hole 5 is 0.31 mm. In addition, the height of the opening of the tapered through-hole 5 at the outer side wall of the end cap 2 is set to be higher than the height of the outer side wall surface of the end cap 2. When the liquid level of the location where the slow-release device is placed is low, the opening of the tapered through-hole 5 can also be immersed in water or a waterway or other liquid.
[0036] A plurality of support blocks 9 are arranged around the outer end edge of the end cap 2.
[0037] When the liquid level of the location where the slow-release device is placed is low, the support blocks 9 can be used for support.
[0038] The inner side wall of the end cap 2 is provided with a mounting groove 10. A plurality of compression strips 11 are arranged at intervals on the groove wall of the mounting groove 10. The weight block 3 is arranged in the mounting groove 10 and is compressed by the compression strips 11.
[0039] The weight block 3 is compressed in the mounting groove 10 by the compression strips 11, so that the weight block 3 is stably mounted in the mounting groove 10.
[0040] The counterweight 3 is made of metal, and the container shell 1 is made of corrosion-resistant polymer compound material, specifically polyethylene.
[0041] The container shell 1 is made of a corrosion-resistant polymer compound material, which can prevent the substances contained in the container shell 1 from being exchanged with places outside the container shell 1.
[0042] The container shell 1 has a cylindrical structure, and the end cap 2 and counterweight 3 are adapted to the structure of the container shell 1.
[0043] Example 2, refer to Figures 6 to 8 The difference between this embodiment and Embodiment 1 is that the container shell 1 has a regular hexagonal structure, and the structures of the end cap 2 and the counterweight 3 are adapted to the structure of the container shell 1.
[0044] Example 3, refer to Figures 9 to 11 The difference between this embodiment and Embodiment 1 is that the container shell 1 has a regular quadrilateral structure, and the structures of the end cap 2 and the counterweight 3 are adapted to the structure of the container shell 1.
[0045] Working principle: The container shell 1 can hold antibacterial solutions, fragrances, medicines, and other substances that need to be released slowly. When in use, the slow-release device is placed in the desired location, which can be water, a waterway, or other liquids. Due to the counterweight 3 set on the inner wall of the end cap 2, the slow-release device is inverted under the action of the counterweight 3, that is, the end cap 2 is facing downwards, so that the slow-release device is suspended, floated, or immersed in water, a waterway, or other liquids. This ensures that the conical through hole 5 can always be immersed in water, a waterway, or other liquids. Then, through the conical through hole 5 in the middle of the end cap 2, under the action of capillary action or gravity, the substance inside the container shell 1 is slowly released into the water, a waterway, or other liquids.
[0046] In addition, this sustained-release device can also be applied to the fields of drug sustained release (treatment, healing, nutritional health care) and fragrance release, so as to achieve the purpose of slowly delivering drugs / nutritional products and slowly diffusing fragrance.
[0047] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
