Description

Technical Field

[0001] The invention relates to the technical field of capsule filter elements, in particular to a capsule filter element with a quick-connect joint. Background Art

[0002] Capsule filter, also known as integrated filter or filter, is a filter device widely used in liquid filtration. It usually has a specific structural design, with an inlet and an outlet on both sides of the filter. The inlet is used to receive the liquid to be filtered, while the outlet discharges the filtered liquid.

[0003] There are two basic connection methods: threaded connection and cannula connection. If threaded connection is used, corresponding threads will be set on the water inlet and outlet of the capsule filter. In this way, the ports of the water inlet and outlet pipes need to be provided with internal threads that match the threaded joints, otherwise they cannot be assembled. When cannula connection is used, the water inlet and outlet will be set in the form of cannula pipes so that the corresponding pipes can be inserted for connection.

[0004] However, each capsule filter element can only choose one of the water inlet or outlet modes, and the connection mode is relatively simple. For example, when encountering a capsule filter element with a threaded joint, if there is no matching internal thread at the port of the water pipe, the connection cannot be made. At this time, the water pipe needs to be replaced with a matching water pipe, which undoubtedly increases the trouble of the operation. It is inconvenient to unify the joints of the capsule filter element so that it can be adaptively connected to water pipes of both threaded connection and cannula connection.

[0005] In view of this, the present invention provides a capsule filter element with a quick-connect joint. Summary of the invention

[0006] The object of the present invention is to provide a capsule filter element with a quick-connect joint to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides a capsule filter element with a quick-connect joint, comprising a capsule filter element body, wherein the outer wall of the capsule filter element body is fixedly connected with a water inlet near the top, and the outer wall of the capsule filter element body is fixedly connected with a drain outlet near the bottom;

[0008] The water inlet and the drain outlet are both movably connected with a detachable assembly, the detachable assembly is movably connected with a gas assembly, the detachable assembly and the gas assembly form a joint, and the auxiliary water pipe is connected inside the water inlet and the drain outlet;

[0009] The disassembly assembly is used to drive the gas assembly as a whole to be installed and disassembled at the ends of the water inlet and the outlet, and is connected to the inside of the auxiliary water pipe thread by rotating. The gas assembly is used to fix water pipes with different connection methods inside the disassembly assembly, while reinforcing the stability of the connected water pipes, and cleaning the outer wall of the water pipe while the disassembly assembly is rotating.

[0010] As a further improvement of the present technical solution, the disassembly assembly includes an outer shell, a gas assembly is fixedly connected to the inner wall of the outer shell, an end cap is fixedly connected between the inner wall of one end of the outer shell away from the gas assembly and the end of the gas assembly, a rotating part is fixedly connected to the end of the end cap, and the end cap and the rotating part are movably connected inside the water inlet and the drain.

[0011] As a further improvement of the present technical solution, the rotating part includes a No. 1 slider, which is fixedly connected to the outer wall of the end head near the end, a coarse elastic part is fixedly connected to the end of the end head, a support ring is fixedly connected to the end of the coarse elastic part, and a No. 2 slider is fixedly connected to the outer wall of the support ring.

[0012] As a further improvement of the present technical solution, the gas component includes an inner cavity, which is fixedly connected to the inner wall of the shell, the inner wall of the inner cavity is provided with a groove with a spiral opening, and an airbag is fixedly connected inside the groove of the inner wall of the inner cavity.

[0013] As a further improvement of the technical solution, a piston is movably connected between the outer wall of the inner cavity and the inner wall of the outer shell, a plurality of push rods are fixedly connected to the end of the piston, and a plurality of push rods pass through the end of the outer shell and are fixedly connected to a pushing member.

[0015] As a further improvement of the technical solution, the airbag is made of a thermoplastic elastomer material, and the airbag is spirally fixedly connected to the spiral groove of the inner wall of the inner cavity.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the capsule filter element with quick-connect joint, the installation and disassembly of the gas assembly at the water inlet and the drain outlet are realized by rotating the disassembly assembly, so that in actual application, when the joint is damaged, it can be quickly replaced, which greatly improves the maintenance efficiency;

[0018] At the same time, the rotation operation can also assist in connecting the disassembly component and the gas component to the threaded water pipe. By rotating, the threads can be gradually tightened, making the connection between the disassembly component, the gas component and the water pipe more reliable. When disassembling, the reverse rotation can easily separate them, and the operation is simple and convenient.

[0019] 2. In the capsule filter element with a quick-connect joint, the water pipe moves between the gas component and the disassembly component, driving the gas inside the gas component to gradually fill up; at the same time, the gas component also supports the water pipe during the connection process, maintaining the stability of the water pipe connection process, and when the disassembly component drives the gas component to rotate, the gas component of the supporting part will generate friction with the outer wall of the water pipe. This friction can clean the outer wall of the water pipe, remove dirt and impurities attached to it, keep the outer wall of the water pipe clean, and help improve the quality and reliability of the connection.

[0020] 3. In the capsule filter element with a quick-connect joint, for the water pipe connected by the thread, the gas component is continuously filled so that it can adapt to the size tolerance of different water pipes according to the adjustment of the inflation amount, thereby improving the versatility and flexibility of the connection and facilitating the connection operation of water pipes of various sizes; and as the thread is continuously inflated and expanded, the tiny gap of the connection part can be better filled, thereby effectively improving the sealing of the connection;

[0021] As for the water pipes connected by the intubation tube, when the water pipes continue to go deeper into the connection part, they can be clamped and fixed through the continuous filling of the gas component to ensure that the water pipes will not loosen or fall off during the connection process; and while fixing, the sealing between the water pipes and the joints is improved, and the pressure of the gas makes the connection fit more tightly, effectively preventing the occurrence of water leakage, air leakage and other problems, and providing a strong guarantee for the stable operation of the water pipe system.

[0036] Example

[0037] See also Figure 1-Figure 5 As shown, the purpose of this embodiment is to provide a capsule filter element with a quick-connect joint, including a capsule filter element body 1, a water inlet 11 is fixedly connected to the outer wall of the capsule filter element body 1 near the top, and a drain outlet 12 is fixedly connected to the outer wall of the capsule filter element body 1 near the bottom;

[0038] The water inlet 11 and the drain outlet 12 are both movably connected with a detachable assembly 13, and the detachable assembly 13 is movably connected with a gas assembly 14. The detachable assembly 13 and the gas assembly 14 form a joint, and an auxiliary water pipe is connected inside the water inlet 11 and the drain outlet 12;

[0039] The disassembly assembly 13 is used to drive the gas assembly 14 to be installed and disassembled as a whole at the ends of the water inlet 11 and the drain outlet 12, and the auxiliary water pipe is threadedly connected inside by rotating. The gas assembly 14 is used to fix water pipes of different connection methods inside the disassembly assembly 13, and at the same time, the stability of the connected water pipes is reinforced, and the outer wall of the water pipe is cleaned while the disassembly assembly 13 is rotating;

[0040] The improvement of this embodiment is that by rotating the detachable assembly 13, it is convenient to install and detach it and the gas assembly 14 at the water inlet 11 and the drain outlet 12, so as to facilitate the replacement of damaged joints. At the same time, its rotation also assists the detachable assembly 13 and the gas assembly 14 to be threadedly connected to the water pipe;

[0041] The water pipe moves between the gas component 14 and the disconnecting component 13, driving the gas inside the gas component 14 to be filled with gas, and the gas component 14 supports the water pipe during the connection process to maintain the stability of the water pipe connection process; and when the disconnecting component 13 drives the gas component 14 to rotate, the gas component 14 also rubs and cleans the outer wall of the water pipe;

[0042] For water pipes with threaded connections, the gas component 14 is continuously filled so that the gas component 14 can adapt to the dimensional tolerances of different water pipes by adjusting the amount of inflation, thereby improving the versatility and flexibility of the connection and facilitating the connection of water pipes of various sizes; and as the threads are continuously inflated and expanded, the tiny gaps in the connection parts can be better filled, thereby effectively improving the sealing of the connection; for water pipes with cannula connections, the gas component 14 is continuously filled so that the water pipes that are continuously inserted deeper can be clamped and fixed, and while fixing the water pipes, the sealing between the water pipes and the joints can be improved.

[0043] First, the specific structure of the detachable assembly 13 is disclosed. The detachable assembly 13 includes a shell 130. The gas assembly 14 is fixedly connected to the inner wall of the shell 130. An end 131 is fixedly connected between the inner wall of one end of the shell 130 away from the gas assembly 14 and the end of the gas assembly 14. A rotating member 132 is fixedly connected to the end of the end 131. The end 131 and the rotating member 132 are both movably connected inside the water inlet 11 and the drain outlet 12.

[0044] See also Figure 3 and Figure 4As shown, by accurately aligning the rotating member 132 with the end of the water inlet 11 or the drain outlet 12; ensuring that the position of the rotating member 132 and the water inlet 11 or the drain outlet 12 accurately corresponds; then, by rotating the outer shell 130 and the end head 131, start to screw the rotating member 132 into the water inlet 11 or the drain outlet 12; during the rotation process, it is necessary to apply appropriate force to ensure that the rotation is smooth and firm; as the outer shell 130 rotates, it will drive the gas component 14 to rotate together; so that the end head 131 will gradually be clamped inside the water inlet 11 or the drain outlet 12 under the action of rotation, effectively preventing the rotating member 132 from loosening or falling off during use, thereby ensuring the reliability and safety of the entire connection system; through such an installation method, not only can the rotating member 132 be firmly connected to the water inlet 11 or the drain outlet 12, but it can also drive the gas component 14 to make corresponding adjustments during the installation process, providing a stable foundation for subsequent water pipe connection and use;

[0045] The rotating member 132 includes a first slider 1320, which is fixedly connected to the outer wall of the end head 131 near the end, a coarse elastic member 1321 is fixedly connected to the end of the end head 131, a support ring 1322 is fixedly connected to the end of the coarse elastic member 1321, and a second slider 1323 is fixedly connected to the outer wall of the support ring 1322;

[0046] First, carefully align the support ring 1322 and the second slider 1323 with the groove at the end of the water inlet 11 or the drain outlet 12; then, by rotating the rotating member 132 as a whole, the position and direction of the second slider 1323 inside the water inlet 11 or the drain outlet 12 can be cleverly turned; in this process, it is necessary to continue to push the support ring 1322 and rotate and adjust the position of the second slider 1323 again, so that the support ring 1322 can be more conveniently pushed to the bottom of the groove at the end of the water inlet 11 or the drain outlet 12;

[0047] When the support ring 1322 successfully moves to the inside of the water inlet 11 or the drain outlet 12, it will drive the coarse elastic member 1321 to enter the water inlet 11 or the drain outlet 12; at the same time, it will also drive the end head 131 to insert into the inner wall of the water inlet 11 or the drain outlet 12; at this time, the No. 1 slider 1320 will be aligned with the groove at the end of the water inlet 11 or the drain outlet 12; by rotating the operation, the direction of the No. 1 slider 1320 can be flexibly adjusted, so that it is convenient to continuously push the end head 131, thereby driving the coarse elastic member 1321 to compress ; Moreover, when the coarse elastic member 1321 is in a compressed state, the end head 131 and the support ring 1322 are driven to rotate simultaneously; by adjusting the direction of the No. 1 slider 1320 again, the No. 1 slider 1320 can be firmly stuck in the groove at the end of the water inlet 11 or the drain outlet 12; it is convenient to install the rotating member 132 with the water inlet 11 or the drain outlet 12; on the contrary, if disassembly operation is required, it is only necessary to rotate the rotating member 132 in the opposite direction, so as to realize the smooth disassembly of the rotating member 132 with the water inlet 11 or the drain outlet 12;

[0048] When the water pipe needs to be threadedly connected, the rotating member 132 is pressed to compress the coarse elastic member 1321 inside it; then, the housing 130 is twisted, so that the end 131 and the rotating member 132 can be driven to rotate as a whole; in this process, the gas component 14 can be easily driven to rotate along the thread direction of the water pipe, thereby realizing the threaded connection of the water pipe; and, during the rotation of the gas component 14, the dirt on the outer wall of the water pipe can also be cleaned by friction; this design not only realizes an efficient connection method, but also can clean the outer wall of the water pipe during the connection process, providing a strong guarantee for the stable operation of the water pipe system;

[0049] Secondly, the specific structure of the gas component 14 is disclosed. The gas component 14 includes an inner cavity 140, which is fixedly connected to the inner wall of the shell 130. The inner wall of the inner cavity 140 is provided with a spiral opening groove, and the inner groove of the inner wall of the inner cavity 140 is fixedly connected with an air bag 141;

[0050] A piston 142 is movably connected between the outer wall of the inner cavity 140 and the inner wall of the outer shell 130, and a plurality of push rods 143 are fixedly connected to the end of the piston 142. The plurality of push rods 143 pass through the end of the outer shell 130 and are fixedly connected to a pusher 144;

[0051] See also Figure 5 , Figure 6 and Figure 7As shown, first, the water pipe interface is accurately aligned with the pusher 144, and then slowly inserted into the inside thereof; during this process, the pusher 144 stabilizes the moving direction of the water pipe interface during the movement; when the water pipe continues to move forward, the flange at the tail of the water pipe interface will gradually touch the pusher 144; as the water pipe continues to move forward, the pusher 144 will be driven to move toward the housing 130 during the continuous movement of the water pipe;

[0052] The movement of the push member 144 further drives the movement of the push rod 143; since the push rod 143 is connected to the piston 142, the movement of the push rod 143 causes the piston 142 to move between the housing 130 and the inner cavity 140; during the movement of the piston 142, it transports the gas in the inner cavity 140; at this time, the gas in the inner cavity 140 moves along the Figure 5 The specific flow direction shown moves; during this flow process, the gas is transported from the threaded groove on the inner wall of the inner cavity 140 to the inside of the airbag 141;

[0053] The airbag 141 is made of thermoplastic elastomer, and is fixedly connected to the spiral groove of the inner wall of the inner cavity 140 in a spiral shape. According to its material characteristics, it has both the processability of plastic and the elasticity of rubber, and has excellent elasticity. It can adjust the hardness and elastic modulus according to different formula designs; and it has good sealing performance against gas, is easy to be inflated by gas, is environmentally friendly and non-toxic, can be recycled, and has relatively low processing costs;

[0054] When the gas enters the airbag 141, the airbag 141 slowly bulges toward the center of the inner cavity 140 along the thread groove under the strong action of the gas; in this process, the airbag 141 gradually forms a gas thread; at the same time, during the movement of the water pipe, the rotating member 132 drives the outer shell 130 and the inner cavity 140 to rotate simultaneously, so that the water pipe can be screwed between the inner cavity 140 and the airbag 141 more smoothly;

[0055] As the water pipe continues to move, gas is continuously transported to the inside of the airbag 141; in this process, the airbag 141 is continuously inflated with the thread, and can better fill the tiny gap of the connection part; the expansion and filling of the airbag 141 can effectively improve the sealing of the connection, ensuring that the water pipe system will not leak during operation; when the water pipe cannot be pushed, it means that the water pipe and the inner cavity 140 are connected and fixed; this design makes it easy for the joint to adapt to the water pipe with threaded connection, and provides reliable protection for the threaded connection;

[0056] For the water pipe connected by the cannula, as the water pipe continues to move, the continuously inflated airbag 141 clamps the water pipe joint, providing a stable fixing force; when the water pipe cannot be pushed, it indicates that the water pipe joint has been fixed to the inner cavity 140; this fixing method ensures that the water pipe will not loosen or fall off during the connection process, greatly improving the stability and reliability of the water pipe connection; and, while fixing, the airbag 141 can also improve the sealing between the water pipe and the joint to prevent leakage of water or other media;

[0057] The push member 144 includes a push plate 1440, which is fixedly connected between the ends of the plurality of push rods 143, a plurality of thin elastic members 1441 are fixedly connected to the inner wall of the push plate 1440, a clamping plate 1442 is fixedly connected to the end of the thin elastic member 1441, and a water pipe is movably connected between the plurality of clamping plates 1442;

[0058] By pushing the multiple clamping plates 1442, the thin elastic member 1441 connected thereto is driven to contract, so that the water pipe joint can be conveniently inserted between the multiple clamping plates 1442; when the water pipe joint is surrounded by the clamping plates 1442, the clamping plates 1442 are subjected to the rebound force of the thin elastic member 1441, and the water pipe is clamped and fixed, which can stabilize the movement of the water pipe, effectively limit the shaking and displacement of the water pipe, ensure the stable position of the water pipe, and lay the foundation for a good connection;

[0059] Since the outer wall of the water pipe joint may be contaminated with dust, dirt or other impurities during storage, transportation or installation, if these impurities are not cleaned up, they may affect the quality and sealing of the connection; therefore, when performing a threaded connection, the rotation of the outer shell 130 will drive the entire gas assembly 14 to rotate together; in this process, the splint 1442 will rub and rotate on the outer wall of the water pipe; before the water pipe is connected to the inner cavity 140, the friction rotation of the splint 1442 can clean the outer wall of the water pipe joint, effectively remove impurities on the outer wall of the water pipe joint, create good conditions for subsequent tight connection, reduce the probability of connection problems caused by impurities, and provide a strong guarantee for the stable operation of the water pipe system.

[0060] In summary, the working principle of this solution is as follows:

[0061] First, align the support ring 1322 and the second slider 1323 with the groove at the end of the water inlet 11 or the drain outlet 12, and rotate the rotating member 132 to adjust the position of the second slider 1323 inside the water inlet 11 or the drain outlet 12; then, continue to push the support ring 1322, and rotate and adjust the position of the second slider 1323 again, so that the support ring 1322 is smoothly pushed to the bottom of the groove at the end of the water inlet 11 or the drain outlet 12;

[0062] When the support ring 1322 moves to the inside of the water inlet 11 or the drain outlet 12, it will drive the coarse elastic member 1321 to enter therein, and at the same time, the end head 131 will also be inserted into the inner wall of the water inlet 11 or the drain outlet 12; at this time, the No. 1 slider 1320 will be aligned with the groove at the end of the water inlet 11 or the drain outlet 12, and the direction of the No. 1 slider 1320 can be adjusted by rotation so as to continuously push the end head 131, thereby driving the coarse elastic member 1321 to compress; when the coarse elastic member 1321 is in a compressed state, the end head 131 and the support ring 1322 are driven to rotate at the same time, and the direction of the No. 1 slider 1320 is adjusted so that the No. 1 slider 1320 is stuck in the groove at the end of the water inlet 11 or the drain outlet 12, thereby facilitating the installation of the rotating member 132 and the water inlet 11 or the drain outlet 12; conversely, the rotating member 132 is rotated in the opposite direction to realize the disassembly of the rotating member 132 and the water inlet 11 or the drain outlet 12;

[0063] In addition, by pushing the multiple clamping plates 1442, the thin elastic member 1441 can be driven to contract, making it easy to insert the water pipe joint between the multiple clamping plates 1442, thereby stabilizing the movement of the water pipe; aligning the water pipe interface with the pushing member 144 and inserting it into the inside thereof can enable the pushing member 144 to stabilize the moving direction of the water pipe interface during the movement; as the water pipe continues to move forward, the flange at the tail of the water pipe interface will touch the pushing member 144, and drive the pushing member 144 to move toward the outer shell 130 during the continuous movement of the water pipe; the pushing member 144 will drive the push rod 143 to move, so that the push rod 143 drives the piston 142 to move between the outer shell 130 and the inner cavity 140, transporting the gas in the inner cavity 140, and moving the gas in the inner cavity 140 along a specific flow direction, thereby inputting the gas from the threaded groove on the inner wall of the inner cavity 140 into the inside of the airbag 141; in this way, the airbag 141 will bulge toward the center of the inner cavity 140 along the threaded groove under the action of the gas, forming a gas thread;

[0064] When threaded connection is performed, it is necessary to press the rotating member 132 to compress the internal thick elastic member 1321 while the water pipe is moving, and twist the outer shell 130 to drive the end head 131 and the rotating member 132 to rotate as a whole, so that the clamping plate 1442 is rubbed and rotated on the outer wall of the water pipe, so that the rotation effect can not only clean the outer wall of the water pipe joint before connecting with the inner cavity 140, but also facilitate the water pipe to be screwed between the inner cavity 140 and the air bag 141;

[0065] Furthermore, as the water pipe continues to move, gas is continuously transported into the airbag 141, so that the airbag 141 expands as the thread is continuously inflated. The airbag 141 can adapt to the dimensional tolerances of different water pipes according to the amount of inflation, better fill the tiny gaps in the connection parts, and effectively improve the sealing of the connection; when the outer shell 130 cannot rotate, it indicates that the threaded connection between the water pipe and the inner cavity 140 is fixed; for the water pipe connected by intubation, the continuously inflated airbag 141 will clamp the water pipe joint through the continuous movement of the water pipe. When the water pipe cannot be pushed, it indicates that the water pipe joint has been fixed to the inner cavity 140, ensuring that the water pipe will not loosen or fall off during the connection process. At the same time, the inflated airbag 141 can also improve the sealing between the water pipe and the joint.
