Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of train water purifier equipment, in particular to a train water purifier filter core structure. BACKGROUND

[0002] With the rapid development of railway transportation, passengers on the train have higher and higher requirements for the quality and safety of drinking water. As a key device to ensure the safety of train drinking water, the performance of the filter core structure of the train water purifier directly affects the purification effect and service life.

[0003] Currently, in order to make the quality of purified water reach the standard of high-quality drinking water, the train water purifier adopts a double-filter core filtering structure to realize multi-level filtration and effectively remove various complex pollutants in train water.

[0004] Due to the particularity of the train operating environment, the train water purifier filter core needs to work continuously for a long time and faces a large water flow impact and water quality fluctuation. During the train running process, various direction shaking occurs, which makes the filter core installed in the filter core bin prone to deflection. Once the filter core is deflected, the sealing of the water pipe connection end will be affected, the sealing effect will decrease, which will increase the risk of water leakage, and at the same time, it may also mix the water that has not been fully filtered into the purified water, affecting the water quality safety. CONTENT OF THE INVENTION

[0005] In order to improve the water quality safety filtered by the train water purifier, the present application provides a train water purifier filter core structure.

[0006] The train water purifier filter core structure provided by the present application adopts the following technical scheme:

[0007] A train water purifier filter core structure, comprising a water purifier shell, two filter cores arranged in the water purifier shell, a filter core bin body and a waterway plate arranged in the water purifier shell, two independent cavities are arranged in parallel on the filter core bin body, one filter core is respectively inserted and installed, the waterway plate is arranged at the end of the filter core bin body, and a water pipe interface is connected between the two filter cores, a fixed frame is arranged on the side of the shell away from the waterway plate, the fixed frame limits the filter core bin in the shell, and an anti-rotation piece is arranged on the fixed frame, square clamping blocks are arranged at the front ends of the filter cores, the clamping blocks are inserted into the anti-rotation piece, and the anti-rotation piece is jointly clamped on the two clamping blocks when the filter cores are inserted into the filter core bin body.

[0008] By adopting the above technical scheme, the two independent chambers arranged in parallel on the filter element bin body ensure that each filter element can be stably installed, avoiding displacement caused by water flow impact or train shaking. The square-shaped clamping block at the front end of the filter element and the plug-in cooperation of the anti-rotation piece not only facilitate the installation and removal of the filter element, but also ensure that the filter element is not easy to loosen during long-time continuous work, thereby ensuring the safety of water quality. The filter element structure of the train water purifier can effectively prevent the deflection of the filter element during use, reduce the risk of seal failure caused by the deflection of the filter element at the water pipe interface, and thereby improve the sealing performance and reliability of the entire system.

[0009] Optionally, the anti-rotation piece is a limiting plate arranged in an H shape, mounting blocks are arranged on both sides of the limiting plate on the fixed frame, fastening bolts are arranged between the limiting plate and the mounting blocks, and the side wall of the limiting plate is attached to the filter element and abuts the filter element against the waterway plate.

[0010] By adopting the above technical scheme, the anti-rotation piece is designed as an H-shaped limiting plate, which can effectively prevent the deflection of the two filter elements in the filter element bin and ensure good sealing with the water pipe interface, thereby avoiding the problem of water leakage caused by shaking. At the same time, the fastening bolt connection between the limiting plate and the mounting block is simple and reliable, which enhances the stability of the entire structure. In addition, the side wall of the limiting plate is attached to the filter element and abuts the filter element against the waterway plate, which further improves the sealing effect and ensures the safety and purification efficiency of the water quality.

[0011] Optionally, the end of the clamping block is provided with a handle for pulling out the filter element.

[0012] By adopting the above technical scheme, the clamping block provided with the handle can significantly improve the operation convenience when replacing the filter element and reduce the working intensity of the maintenance personnel. Especially when operating in a small space, the design of the handle makes it easier to pull out or insert the filter element, thereby improving the working efficiency and safety.

[0013] Optionally, the handle is provided with a pointing mark.

[0014] By adopting the above technical scheme, the pointing mark provided on the handle can facilitate the operator to quickly identify and operate the direction of the filter element plug-in, thereby improving the working efficiency when replacing or maintaining the filter element.

[0015] Optionally, the two filter elements are 3IN1 filter elements and RO filter elements, respectively.

[0016] By adopting the above technical scheme, the combination of the 3IN1 filter element and the RO filter element can achieve multi-level filtering effect. The 3IN1 filter element can effectively remove large-particle impurities, suspended solids and part of organic matter in water, and the RO filter element can further remove soluble inorganic salts, heavy metal ions and other small-molecule substances. This double filtration method not only improves the safety and purity of water quality, but also prolongs the service life of the entire filter element structure, ensuring that the train water purifier can continuously and stably provide high-quality drinking water in complex and variable operating environments.

[0018] By adopting the above technical scheme, the sealing effect between the filter element and the water circuit board can be significantly improved. Specifically, the arrangement of the rubber sealing ring can maintain good sealing state under water flow impact, further reduce the water leakage phenomenon caused by filter element deflection, reduce the possibility of pollution of filtered water quality, thereby improving the overall reliability and use safety of the train water purifier.

[0019] Optionally, the anti-rotation member includes two clamping blocks inserted into the clamping blocks, a guide rod that passes through the two filter elements, and a locking member that locks the positions of the two clamping blocks. The guide rod is vertically arranged on the fixed frame. The clamping blocks are slidably arranged on the guide rod. The clamping blocks are located on the opposite sides of the two filter elements and are arranged on the fixed frame in opposite sliding manner.

[0020] By adopting the above technical scheme, the insertion and cooperation between the clamping block and the clamping block ensure the stability and accuracy of the filter element when inserted into the filter element compartment, avoiding the sealing failure or water leakage phenomenon caused by train shaking. The design of the guide rod enables the clamping block to slide on the fixed frame, so that the clamping position can be adjusted according to actual needs, enhancing the adaptability and flexibility of the device. The locking member locks the clamping block after adjusting the position, further improving the stability of the filter element during use, ensuring the reliability and safety of long-term use.

[0021] Optionally, the locking member includes a bidirectional screw rod that rotatably connects the two clamping blocks, and a positioning rod that inserts the bidirectional screw rod and the guide rod. The bidirectional screw rod is parallel to the guide rod and located on the side of the two filter elements away from the guide rod. The threaded section of the bidirectional screw rod corresponds to the clamping block one by one. The middle section of the bidirectional screw rod is provided with a positioning hole. The positioning rod is arranged between the two filter elements in an extendable manner. One end of the positioning rod is connected to the guide rod, and the other end passes through the positioning hole and is inserted into the bidirectional screw rod. The positioning rod and the positioning hole are inserted and cooperated.

[0022] By adopting the above technical scheme, the design of the locking part can not only ensure that the two clamping blocks are stably fixed on the guide rod to prevent the filter core from deflecting due to train shaking, but also realize precise positioning through adjustment of the bidirectional screw rod to ensure the close contact between the filter core and the waterway plate, thereby improving the sealing performance and stability of the overall device, further reducing the risk of water leakage and ensuring water quality safety.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The two independent chambers arranged in parallel on the filter core compartment ensure that each filter core can be stably installed, avoiding displacement caused by water flow impact or train shaking.

The filter core structure of the train water purifier can effectively prevent the filter core from deflecting during use, reducing the risk of seal failure at the filter core and water pipe interface due to filter core deflection, thereby improving the sealing performance and reliability of the entire system;

[0025] 2. The anti-rotation part is designed as an H-shaped limiting plate, which can effectively prevent both filter cores from deflecting in the filter core compartment, ensuring good sealing with the water pipe interface and avoiding water leakage caused by shaking.

[0034] The application discloses a filter core structure of a train water purifier.

[0035] Embodiment 1

[0036] Referring to Figure 1 and Figure 2 A filter core structure of a train water purifier includes a water purifier shell 1, a filter cartridge body 2 and a waterway board 3 are arranged in the water purifier shell 1, two independent cavities are arranged in parallel on the filter cartridge body 2, and one filter core 4 is respectively inserted into each cavity. The waterway board 3 is fixedly arranged at the end of the filter cartridge body 2, water pipe interfaces 5 are arranged in butt joint between the two filter cores 4 and the waterway board 3, and rubber sealing rings 51 are arranged around the butt joint water pipe interfaces 5. A fixed frame 6 is fixedly arranged on the side of the shell away from the waterway board 3, and the fixed frame 6 limits the filter cartridge in the shell. Square clamping blocks 41 are fixedly arranged at the front ends of the filter cores 4, and anti-rotation pieces 7 for fixing the clamping blocks 41 are arranged on the fixed frame 6.

[0037] Referring to Figure 1 In the embodiment, the two filter cores 4 are respectively a 3IN1 filter core and an RO filter core, the 3IN1 filter core is inserted into the upper cavity, and the RO filter core is inserted into the lower cavity. The 3IN1 filter core and the RO filter core are commercially available, and the internal structure diagram is not shown. The external water source first enters the PP cotton filter layer in the 3IN1 filter core to intercept and remove the silt, rust and various particulate impurities in the water; then flows into the compressed activated carbon filter layer under the action of water permeation pressure to capture and remove the harmful substances such as residual chlorine, color, odor and organic matter in the water; then the preliminarily filtered water enters the RO filter core to remove the heavy metal elements and other harmful components in the water; finally, the purified water is guided into the post-positioned activated carbon layer in the 3IN1 filter core, the post-positioned activated carbon layer usually uses Sri Lanka coconut shell activated carbon, and the water filtered through the post-positioned activated carbon layer can improve the taste of the water to ensure that the drinking water has a more pure and sweet taste.

[0038] Referring to Figure 1In order to facilitate replacement of the filter element, the front end of the clamping block 41 is fixedly provided with a handle 411, and the handle 411 is electroplated with a pointing mark 4111, which helps the user to quickly identify the direction of the filter element.

[0039] With reference to Figure 1 The anti-rotation piece 7 in the embodiment is a limiting plate 71 arranged in an H shape. The fixed frame 6 is fixedly provided with mounting blocks 61 on both sides of the limiting plate 71, and the limiting plate 71 and the mounting blocks 61 are jointly provided with fastening bolts 611. The fastening bolts 611 abut the limiting plate 71 against the mounting blocks 61, and the side wall thereof is attached to the filter element 4. The clamping block 41 is inserted into the limiting plate 71 and is in insertion fit with the limiting plate 71. When the filter element 4 is inserted into the filter element storage body 2, the limiting plate 71 is jointly clamped on the two clamping blocks 41, and the side wall of the limiting plate 71 is attached to the filter element 4 and abuts the filter element 4 against the waterway plate 3.

Then, the limiting plate 71 is fixed to the fixed frame 6 through the fastening bolts 611. At this time, the side wall of the limiting plate 71 is attached to the filter element 4 and abuts the filter element 4 against the waterway plate 3. This can ensure that the filter element 4 can maintain a stable state in any case, and avoids sealing failure and water pollution caused by deflection of the filter element 4. Meanwhile, the rubber sealing ring 51 is arranged, which further enhances the sealing performance of the filter element 4 and the water pipe interface 5, and improves the reliability and safety of the entire water purification system.

[0041] Embodiment 2

[0042] With reference to Figure 3 and Figure 4 The difference between the embodiment and the embodiment 1 is that the structure of the anti-rotation piece 7 is different. The anti-rotation piece 7 in the embodiment includes clamping blocks 72, guide rods 73 and locking pieces 74. The clamping blocks 72 are arranged on the opposite sides of the two filter elements 4, and are in insertion fit with the clamping blocks 41. The clamping blocks 72 are fixedly provided with rubber pads 8 in the grooves of the clamping blocks 41, and the two clamping blocks 72 are slidably arranged on the fixed frame 6. The guide rods 73 are vertically fixedly arranged on the fixed frame 6, and the two clamping blocks 72 are slidably arranged on the guide rods 73.

[0043] With reference to Figure 3 and Figure 4The locking member 74 includes a bidirectional screw rod 741 and a positioning rod 742. The bidirectional screw rod 741 is parallel to the guide rod 73 and is rotatably arranged on the fixed frame 6 at the side of the two filter cartridges 4 away from the guide rod 73. The threaded section of the bidirectional screw rod 741 corresponds to the clamping block 72 one by one, and the clamping block 72 is rotatably sleeved on the bidirectional screw rod 741 through threads. The middle section of the bidirectional screw rod 741 is provided with a positioning hole 7411, and the positioning rod 742 is arranged between the two filter cartridges 4 in an extendable manner. The fixed block 9 is fixedly arranged on the water purifier shell 1 along the extension line of the length direction of the positioning rod 742. One end of the positioning rod 742 is fixedly arranged on the guide rod 73, the other end is inserted into the fixed block 9 through the positioning hole 7411, and the extension end of the positioning rod 742 is inserted and matched with the positioning hole 7411.

[0044] The implementation principle of embodiment 2 is that by adopting the design of the anti-rotation member 7 combined with the clamping block 72 and the bidirectional screw rod 741, a more flexible and reliable filter cartridge fixing scheme is realized. This way not only prevents the filter cartridge 4 from deflecting during train operation, but also has the convenience of adjustment and maintenance. Users only need to rotate the bidirectional screw rod 741 to easily disassemble and install the filter cartridge 4, greatly simplifying the maintenance process. In addition, through the design of the positioning rod 742, the stability of the anti-rotation member 7 is further enhanced, ensuring the good performance of the filter cartridge 4 in long-term use. This design not only prolongs the service life of the filter cartridge 4, but also improves the reliability and user experience of the entire water purification system.

[0045] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
