Abstract
Description
Technical Field
[0001] This utility model belongs to the field of conical flask technology, and particularly relates to a seawater filtration conical flask. Background Technology
[0002] A conical flask for seawater filtration refers to a conical flask used in seawater filtration or related experimental procedures. A conical flask is a common laboratory glass instrument made of hard glass with a triangular longitudinal section. It has the structural characteristics of a small mouth and a large base. This design can prevent liquid from splashing during titration or shaking reactions, while facilitating stirring and heating. In seawater filtration or treatment experiments, conical flasks may be used to receive the filtered filtrate, store seawater samples under treatment, or serve as reaction vessels for chemical treatment. Currently, conical flasks are usually placed on a support frame during use.
[0003] Chinese patent publication number 202420757737.7 discloses a conical flask for precise liquid dispensing, comprising a flask body, a metering dispensing cylinder disposed inside the flask body's opening, a connecting assembly connected to the flask body, an inlet at the bottom of the dispensing cylinder, and an upper fixed cover plate fixedly connected to the top of the dispensing cylinder. An opening and closing assembly is connected to the surface of the upper fixed cover plate. This invention utilizes a rotating block that rotates a connecting shaft, causing the connecting shaft to rotate the opening and closing plate, thus removing the obstruction of the inlet. The flask body is then tilted and vertically inverted, allowing liquid to enter the dispensing cylinder through the inlet. Once the dispensing cylinder is full, the rotating block is rotated again, causing the opening and closing plate to block the inlet. The sealing plug is then removed, and the liquid is discharged through a drain pipe, achieving precise metering of liquid.
[0004] However, existing technologies have the following problems when used:
[0005] 1. When filtering large amounts of seawater and treating the filtrate in traditional conical flasks, frequent manual pouring is not only inefficient but also consumes a lot of time and energy for the experimenters, seriously affecting the progress of the work.
[0006] 2. Currently, conical flasks are usually placed directly on a support frame. When the conical flask is shaken by the outside world, it is easy for it to fall off, which reduces the service life of the conical flask. Utility Model Content
[0007] The purpose of this invention is to address the aforementioned technical problems by providing a seawater filtration conical bottle.
[0008] This technical solution includes,
[0009] The bottle body has a valve at the bottom for discharging seawater from the bottom of the bottle body. An elastic ring is bonded to the bottom of the bottle body. The inner wall of the elastic ring has a recessed portion, and the outer wall of the elastic ring has an extended portion.
[0010] The support ring has a mounting groove at its top end, which is adapted to the elastic ring and is used to limit the elastic ring. The inner side wall of the mounting groove has a limiting groove for engaging with the extension portion.
[0011] During the process of the bottle body moving the elastic ring and the extension part to the mounting groove, the extension part is subjected to the squeezing force of the inner sidewall of the mounting groove, and can generate elastic deformation along the direction of the recess; after entering the limiting groove, the extension part can rebound and be limited in the limiting groove.
[0012] Furthermore, a first connecting pipe is provided at the bottom of the bottle body, the first connecting pipe is connected to the input end of the valve, and a second connecting pipe is connected to the output end of the valve.
[0013] Furthermore, a plurality of mounting heads are connected to the outer wall of the second connecting pipe, the mounting heads being used to connect to the pipe, and at least two of the mounting heads are of different sizes.
[0014] Furthermore, the plurality of mounting heads are arranged in a ring array on the outer side wall of the second connecting pipe.
[0015] Furthermore, each of the mounting heads has a threaded groove in its inner cavity, and a threaded plug is threadedly connected to the threaded groove.
[0016] Furthermore, both the elastic ring and the extension portion are integrally molded from silicone material.
[0017] Furthermore, a movable rod is vertically slidably arranged at the bottom of the inner cavity of the mounting groove, and a top ring is fixedly connected to the top of the movable rod. An inclined part for ejecting the elastic ring is provided on the upper end of the inner side wall of the top ring.
[0018] Furthermore, the bottom end of the movable rod penetrates the bottom of the inner cavity of the mounting groove and is fixedly connected to a toggle ring, and a spring is fixedly connected between the top of the toggle ring and the bottom of the support ring.
[0019] Furthermore, the spring is disposed on the outside of the movable rod, and both the spring and the movable rod are arranged in a circumferential pattern with the axis of the mounting groove as the center.
[0020] Furthermore, multiple sets of support legs are fixedly connected to the outer wall of the support ring.
[0021] Compared with the prior art, the seawater filtration conical bottle of this utility model has the following advantages:
[0022] 1. In terms of filtrate treatment, the bottom of the bottle is connected by a first connecting pipe, a valve, and a second connecting pipe to allow the filtered seawater to be discharged from the bottom. The operator can control the flow by turning the valve, eliminating the need for manual pouring and solving the inefficiency problem of frequent pouring when filtering large amounts of seawater. This saves manpower and time and ensures work progress. At the same time, the multi-size mounting head of the second connecting pipe can be adapted to different specifications of external pipes without replacing the entire component, making it highly versatile. The unused mounting head can also be sealed with a threaded plug to prevent leakage and impurity intrusion.
[0023] 2. The elastic ring formed by the one-piece silicone molding at the bottom of the bottle body cooperates with the support ring, allowing the bottle body to be assembled with the support frame. After the extension part is squeezed and deformed by the mounting groove, it will automatically spring back and lock into the limiting groove to achieve a stable connection. When disassembling, simply pull the actuating ring, and the movable rod will drive the tilting part of the top ring to smoothly push out the elastic ring. There is no need to manually pull it. With the automatic reset function of the spring, the disassembly and assembly process is simplified. Attached Figure Description

[0037] like Figures 1-5 As shown, a seawater filtration conical flask includes:
[0038] Bottle body 100, the bottom of bottle body 100 is provided with a valve 120 for discharging seawater from the bottom end of bottle body 100, and an elastic ring 140 is bonded to the bottom of bottle body 100. The inner side wall of elastic ring 140 is provided with a recess 141, and the outer side wall of elastic ring 140 is provided with an extension 142.
[0039] The support ring 200 has a mounting groove 210 at its top end. The mounting groove 210 is adapted to the elastic ring 140 and is used to limit the elastic ring 140. The inner side wall of the mounting groove 210 has a limiting groove 220 for engaging with the extension portion 142.
[0040] During the process of the bottle body 100 moving the elastic ring 140 and the extension part 142 to the mounting groove 210, the extension part 142 is subjected to the squeezing force of the inner side wall of the mounting groove 210, and can generate elastic deformation along the direction of the recess 141; after entering the limiting groove 220, the extension part 142 can rebound and be limited in the limiting groove 220.
[0041] During assembly, this application only requires moving the bottle body 100 downwards, causing the elastic ring 140 and the extension portion 142 to enter the mounting groove 210. At this time, the extension portion 142 is squeezed by the inner wall of the mounting groove 210 and will naturally produce elastic deformation along the direction of the recessed portion 141, allowing it to be easily embedded without the aid of tools. When the extension portion 142 moves to the position of the limiting groove 220, it will automatically spring back and lock into the limiting groove 220, thus realizing the quick assembly of the bottle body 100 and the support ring 200. Through the setting of the valve 120, the seawater can be discharged from the bottom of the bottle body 100 after filtration, without having to pour it out from the bottle mouth of the bottle body 100, making it convenient to use.
[0042] In the example of this application, a first connecting pipe 110 is provided at the bottom of the bottle body 100, the first connecting pipe 110 is connected to the input end of the valve 120, and the output end of the valve 120 is connected to a second connecting pipe 130.
[0043] As a preferred example of this utility model, a first connecting pipe 110 is provided at the bottom of the bottle body 100. The other end of the first connecting pipe 110 is connected to the input end of the valve 120, and the output end of the valve 120 is connected to a second connecting pipe 130. After the seawater in the bottle body 100 has been filtered, it will first flow into the first connecting pipe 110, and then enter the second connecting pipe 130 through the valve 120. The operator can control the discharge and stop of seawater from the bottom of the bottle body 100 by turning the valve 120.
[0044] In the example of this application, a plurality of mounting heads 131 are provided on the outer side wall of the second connecting pipe 130. The mounting heads 131 are used to connect to the pipe, and at least two mounting heads 131 are of different sizes.
[0045] As a preferred example of this utility model, multiple mounting heads 131 of different sizes are connected to the outer wall of the second connecting pipe 130. The mounting heads 131 can be connected to external pipes of different specifications respectively, so that the device can be adapted to various usage scenarios without replacing the entire second connecting pipe 130, thus improving the versatility of the device.
[0046] In the example of this application, multiple mounting heads 131 are arranged in a ring array on the outer side wall of the second connecting pipe 130.
[0047] As a preferred example of this utility model, the multiple mounting heads 131 distributed in a ring array are capable of being connected to external pipes of different specifications.
[0048] In the example of this application, each mounting head 131 has a threaded groove in its inner cavity, and a threaded plug 132 is threadedly connected in the threaded groove.
[0049] As a preferred example of this utility model, each mounting head 131 has a threaded groove in its inner cavity. When a mounting head 131 is not in use, a threaded plug 132 can be threaded into the threaded groove of the mounting head 131, which can prevent filtered seawater from leaking out of the idle mounting head 131.
[0050] In the example of this application, both the elastic ring 140 and the extension portion 142 are integrally molded from silicone material.
[0051] As a preferred example of this utility model, both the elastic ring 140 and the extension portion 142 are integrally molded from silicone material. Silicone material has elasticity and corrosion resistance. The integral molding process not only ensures that there are no gaps between the elastic ring 140 and the extension portion 142, but also ensures that the extension portion 142 can maintain stable elastic performance after multiple compression deformations and rebounds, thus ensuring the durability of the structure.
[0052] In the example of this application, a movable rod 230 is vertically slidably provided at the bottom of the inner cavity of the mounting groove 210, and a top ring 240 is fixedly connected to the top of the movable rod 230. An inclined portion 241 for ejecting the elastic ring 140 is provided at the upper end of the inner side wall of the top ring 240.
[0053] As a preferred example of this utility model, a movable rod 230 is slidably disposed vertically at the bottom of the inner cavity of the mounting groove 210 of the support ring 200. A top ring 240 is fixedly connected to the top of the movable rod 230, and an inclined portion 241 is machined on the upper end of the inner side wall of the top ring 240. When it is necessary to disassemble the bottle 100, simply push the movable rod 230 upward along the bottom of the inner cavity of the mounting groove 210. The movable rod 230 will then drive the top ring 240 to move upward synchronously. At this time, the inclined portion 241 of the inner side wall of the top ring 240 will contact the bottom of the elastic ring 140 and apply an upward pushing force through the inclined surface to smoothly push the elastic ring 140 out of the mounting groove 210 without manually pulling the elastic ring 140, which is convenient for subsequent reassembly.
[0054] In the example of this application, the bottom end of the movable rod 230 passes through the bottom of the inner cavity of the mounting groove 210 and is fixedly connected to a toggle ring 232. A spring 231 is fixedly connected between the top of the toggle ring 232 and the bottom of the support ring 200.
[0055] As a preferred example of this utility model, the bottom end of the movable rod 230 penetrates the bottom of the inner cavity of the mounting groove 210 and extends downwards to be fixedly connected to a toggle ring 232. A spring 231 is fixedly connected between the top of the toggle ring 232 and the bottom of the support ring 200. When disassembling the bottle body 100, the operator only needs to pull the toggle ring 232 upwards to drive the movable rod 230 to slide towards the bottle. After releasing the toggle ring 232, the spring 231 will return to its original state under its own elasticity, causing the toggle ring 232 and the movable rod 230 to automatically reset.
[0056] In the example of this application, the spring 231 is disposed on the outside of the movable rod 230, and both the spring 231 and the movable rod 230 are arranged in a circumferential shape with the axis of the mounting groove 210 as the center.
[0057] As a preferred example of this utility model, the spring 231 is sleeved on the outside of the movable rod 230, and both the spring 231 and the movable rod 230 are circumferentially distributed with the axis of the mounting groove 210 as the center; this allows multiple sets of movable rods 230 and springs 231 to be evenly stressed. When the actuating ring 232 is pushed, all movable rods 230 will synchronously drive the top ring 240 to rise and fall, preventing the top ring 240 from tilting due to uneven stress, and ensuring that the inclined part 241 of the inner wall of the top ring 240 can fully contact the elastic ring 140, and smoothly push the elastic ring 140 out.
[0058] In the example of this application, multiple sets of support legs 250 are fixedly connected to the outer wall of the support ring 200.
[0059] As a preferred example of this utility model, multiple sets of support legs 250 are fixedly connected to the outer wall of the support ring 200. The support legs 250 are evenly distributed along the outer wall of the support ring 200, which can ensure the stability of the entire filtration device.
[0060] In use, the bottle body 100 serves as a filter carrier. An elastic ring 140 with a recessed portion 141 and an extended portion 142 is bonded to its bottom and connected to a first connecting pipe 110. The elastic ring 140 and the extended portion 142 are integrally molded from silicone. During assembly, the bottle body 100 drives the elastic ring 140 to embed into the mounting groove 210 at the top of the support ring 200. The extended portion 142 is squeezed by the inner wall of the mounting groove 210 and deforms along the recessed portion 141, automatically rebounding and locking after entering the limiting groove 220, thus achieving the installation of the bottle body 100 and the support ring 200. The first connecting pipe 110 at the bottom of the bottle body 100 is connected to the input end of the valve 120, and the output end of the valve 120 is connected to the second connecting pipe 130. The operator can control the flow of seawater from the first connecting pipe 110 to the second connecting pipe 130 through the valve 120. The discharge of 0 is switched on and off, while multiple mounting heads 131 of different sizes connected to the outer wall of the second connecting pipe 130 can be adapted to various specifications of external pipes. The idle mounting head 131 is sealed by the threaded plug 132 to prevent seawater leakage and impurities from entering. When disassembly and maintenance are required, the actuating ring 232 at the bottom of the support ring 200 is pulled upward, which can drive the movable rod 230 that passes through the bottom of the inner cavity of the mounting groove 210 to move upward. The spring 231 sleeved on the outside of the movable rod 230 is compressed, and the inclined part 241 at the upper end of the inner wall of the top ring 240 can push out the elastic ring 140, causing the elastic ring 140 to deform and move out of the limiting groove 220. Finally, after the actuating ring 232 is released, the spring 231 rebounds and drives the movable rod 230 and the top ring 240 fixed at the top to reset, realizing the disassembly of the bottle body 100 and the support ring 200.
[0061] The embodiments of this application have been described above with reference to the accompanying drawings.
