Description

Technical Field

[0001] This utility model belongs to the field of pipeline technology, specifically relating to a water circulation pipeline for an electric heater with a detachable filter structure. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] A prior art patent, CN218188230U, describes a filter pipe comprising a first pipe and a second pipe. Each of the first and second pipes has a fixing ring at one end. A filter pocket is fixedly installed on one side of each fixing ring. An installation groove is formed on one side of each fixing ring. An installation block is fixedly installed at one end of each of the first and second pipes, and the installation block is inserted into the installation groove. An insertion hole is formed on one side of the installation block. A through hole is formed on the side of the fixing ring near the insertion hole. A rod is movably installed within the through hole of the fixing ring. The side is inserted into the socket, and the fixing ring is provided with a receiving groove at the side end of the through hole. The side end of the insertion rod is fixedly installed with a support ring. Its structure is simple, easy to use, and has strong connectivity. It has a good filtration effect and is convenient for temporary fixation of the filter bag. It is convenient for the installation and disassembly of the filter bag. However, in actual use, there are still the following shortcomings: From a practical point of view, it is not convenient to disassemble and clean the filter device of the pipeline separately, and it is not convenient to carry out modular installation work, thereby reducing the practicality of the device. At the same time, it lacks tight installation connection work, which reduces its sealing and leak-proof performance.

[0004] Therefore, there is a need for a water circulation pipe for electric heaters with a detachable filter structure to solve the problems of inconvenient modular installation and connection and inability to ensure tight connection in existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a water circulation pipe for an electric heater with a detachable filter structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water circulation pipe for an electric heater with a detachable filter structure, comprising a first pipe and a second pipe, a filter pipe disposed between the first pipe and the second pipe, a positioning cylinder fixedly connected to the outside of the opposite side of the first pipe and the second pipe, a connecting mechanism disposed on the filter pipe near the first pipe and the second pipe respectively, the filter pipe being detachably connected between the first pipe and the second pipe through the connecting mechanism, a viewing window disposed on the filter pipe, and a filter element fixedly installed inside the filter pipe.

[0007] It should be noted in the solution that the connecting mechanism includes a positioning block, which is fixedly connected to the outside of the positioning cylinder. A positioning hole is provided through the positioning block. A U-shaped block is fixedly connected to the outside of the filter pipe corresponding to the positioning block. A positioning component is provided on the U-shaped block corresponding to the positioning hole. An L-shaped locking block is fixedly connected to the inner surface of the positioning cylinder corresponding to the positioning block. A sealing gasket is fixedly connected to one side of the inside of the first pipe. A matching matching block is provided on the filter pipe corresponding to the L-shaped locking block.

[0008] It is worth noting that four positioning blocks are provided on the outside of the positioning cylinder, and the four positioning blocks are evenly distributed on the outside of the positioning cylinder. The four U-shaped blocks are provided on the outside of the filter pipe in correspondence with the positioning blocks.

[0009] It should be further noted that four L-shaped blocks are provided inside the positioning cylinder.

[0010] In a preferred embodiment, the matching block and the L-shaped card block are arranged in an L-shape, and the matching block and the L-shaped card block are centrally symmetrical.

[0011] In a preferred embodiment, the positioning component includes a mounting groove formed on a U-shaped block. A positioning rod is slidably mounted in the mounting groove, and a positioning ring is fixedly connected to the positioning rod.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a water circulation pipe for an electric heater with a detachable filter structure, including a first pipe 1 and a second pipe 2. A filter pipe 3 is provided between the first pipe 1 and the second pipe 2. A positioning cylinder 4 is fixedly connected to the outside of the opposite side of the first pipe 1 and the second pipe 2. A connecting mechanism 5 is provided on the filter pipe 3 near the first pipe 1 and the second pipe 2 respectively. The filter pipe 3 is detachably connected to the first pipe 1 and the second pipe 2 through the connecting mechanism 5. A viewing window 301 is provided on the filter pipe 3. A filter element 302 is fixedly installed inside the filter pipe 3.

[0023] In use, the filter pipe 3 is installed and connected between the first pipe 1 and the second pipe 2 through the connecting mechanism 5. The filter element 302 can perform filtration on the connected first pipe 1 and second pipe 2, and the status of the filter element 302 can be observed through the viewing window 301. This facilitates the disassembly and cleaning of the filter pipe 3 according to its usage status. The modular filter pipe 3, together with the connecting mechanism 5, allows for independent modular installation and disassembly of the filter pipe 3, which facilitates individual disassembly and cleaning of the filter pipe 3 and improves the practicality of the device.

[0024] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting mechanism 5 includes a positioning block 501, which is fixedly connected to the outside of the positioning cylinder 4. A positioning hole 502 is provided through the positioning block 501. Four positioning blocks 501 are evenly distributed on the outside of the positioning cylinder 4. Four U-shaped blocks 503 are also provided on the outside of the filter pipe 3, corresponding to the positioning blocks 501. A U-shaped block 503 is fixedly connected to the outside of the filter pipe 3 corresponding to the positioning block 501, and the U-shaped block 503 has a corresponding positioning hole. 502 is provided with a positioning component 504. The positioning block 501 is fixedly connected to an L-shaped locking block 505 on the inner surface of the positioning cylinder 4. There are four L-shaped locking blocks 505 inside the positioning cylinder 4. A sealing gasket 506 is fixedly connected to one side of the L-shaped locking block 505 inside the first pipe 1. A matching matching block 507 is provided on the filter pipe 3 corresponding to the L-shaped locking block 505. The matching block 507 and the L-shaped locking block 505 are matched in an L-shape and are centrally symmetrical.

[0025] In use, the matching block 507 rotates and engages within the L-shaped locking block 505. Combined with the sealing gasket 506, this improves the tightness of the connection between the first pipe 1 or the second pipe 2 and the filter pipe 3, thereby enhancing the sealing performance. By releasing the positioning through the positioning hole 502, the filter pipe 3 can be rotated to detach from the positioning block 501 via the U-shaped block 503, facilitating the disassembly of the filter pipe 3. This completes the disassembly and cleaning of the filter pipe 3, improving the practicality of the device.

[0026] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the positioning component 504 includes a mounting groove 5041, which is opened on the U-shaped block 503. A positioning rod 5042 is slidably installed in the mounting groove 5041. The positioning rod 5042 is located on the U-shaped block 503 corresponding to the positioning hole 502. A positioning ring 5043 is fixedly connected to the positioning rod 5042. The positioning rod 5042 slides within the mounting groove 5041 through the positioning ring 5043. A spring 5044 is sleeved on the outside of the positioning rod 5042. The spring 5044 is located in the mounting groove 5041 through the positioning ring 5043. A screw 5045 is fixedly connected to the end of the positioning rod 5042. The screw 5045 is provided with a threaded groove 5046 on the U-shaped block 503.

[0027] In use, by pulling the positioning rod 5042, the positioning rod 5042 slides within the mounting groove 5041 via the positioning ring 5043, thereby disengaging the positioning rod 5042 from the positioning hole 502 to release the positioning block 501 from its limit. Furthermore, through the setting of the screw 5045 and the threaded groove 5046, when positioning is performed by the positioning rod 5042, rotating the positioning rod 5042 causes the screw 5045 to be threaded into the threaded groove 5046, completing the positioning work of the positioning rod 5042 and improving the stability of the positioning. Moreover, when the positioning rod 5042 is pulled out, the threaded connection of the positioning rod 5042 on the U-shaped block 503 can be used to position the disassembly process, thereby improving the convenience of the disassembly operation.

[0028] This solution has the following working process: When this device is in use, the filter pipe 3 is installed and connected between the first pipe 1 and the second pipe 2 through the connecting mechanism 5. The filter element 302 can perform filtration on the connected first pipe 1 and the second pipe 2, and the status of the filter element 302 can be observed through the viewing window 301, which facilitates the disassembly and cleaning of the filter pipe 3 according to the usage status. When disassembling and cleaning the filter pipe 3, the positioning rod 5042 is pulled, causing the positioning rod 5042 to slide in the mounting groove 5041 through the positioning ring 5043, thereby disengaging the positioning rod 5042 from the positioning hole 502, so as to release the positioning block 501 from the limit. Furthermore, through the setting of the screw 5045 and the threaded groove 5046, when positioning by the positioning rod 5042, the positioning rod 5044 is rotated. 2. The screw 5045 is threaded into the threaded groove 5046, completing the positioning of the positioning rod 5042 and improving the stability of the positioning. When the positioning rod 5042 is pulled out, the threaded connection of the positioning rod 5042 on the U-shaped block 503 can position the disassembly process, thereby improving the convenience of the disassembly operation. Furthermore, the matching block 507 rotates and engages in the L-shaped locking block 505, and with the setting of the sealing gasket 506, the tightness of the connection between the first pipe 1 or the second pipe 2 and the filter pipe 3 can be improved, thereby improving the sealing performance. The positioning is released by the positioning hole 502. At this time, by rotating the filter pipe 3, it is easy to detach the filter pipe 3 from the outside of the positioning block 501 through the U-shaped block 503, so as to facilitate the disassembly of the filter pipe 3. This completes the disassembly and cleaning of the filter pipe 3, improving the practicality of the device.

[0029] In summary: The modular filter pipe 3, in conjunction with the connecting mechanism 5, allows for independent modular installation and disassembly of the filter pipe 3, facilitating individual disassembly and cleaning and improving the practicality of the device. The connecting mechanism 5, in conjunction with the positioning cylinders 4 on the first pipe 1 and the second pipe 2, enables quick and convenient installation of the filter pipe 3. Furthermore, the sealing gasket 506 enhances the tightness of the connection process, thereby ensuring its airtightness.
