Description

Technical Field

[0001] This utility model relates to the field of direct drinking water purification technology, and in particular to a direct drinking water purification device. Background Technology

[0002] As an important facility in modern homes and commercial spaces, direct drinking water purification equipment's core function is to remove impurities, bacteria, and harmful substances from water through a multi-stage filtration system, ensuring that the output water meets the standards for direct drinking. With people's increasing demand for healthy drinking water, the popularity of water purification equipment is growing year by year. However, the ease of use and maintenance has become a key concern for users. Traditional water purification equipment usually adopts a fixed filter cartridge design. As the core component of the filtration system, the filter cartridge needs to be replaced regularly to maintain the purification effect. However, the disassembly and assembly methods of existing equipment filter cartridges are often quite complicated, causing many inconveniences for users during maintenance. A technical solution that can simplify operation and improve efficiency is needed.

[0003] In existing direct drinking water purification equipment, the installation and fixing of filter cartridges usually rely on threaded connections. Threaded connections require users to manually rotate the filter cartridge multiple times to achieve a tight fit. Although this meets basic functional requirements to a certain extent, in actual use, threaded connections are prone to wear, which can lead to a decrease in sealing performance. In addition, the sealing performance of quick-connect fittings is greatly affected by the installation accuracy and is prone to leakage problems.

[0004] The most prominent problem in existing technologies is the cumbersome disassembly process and low maintenance efficiency of filter cartridges. Traditional filter cartridge fixing methods usually require users to use tools to complete the disassembly, and the operation steps are complicated and time-consuming. For example, threaded connections need to be repeatedly tightened, which not only increases the user's maintenance burden, but also affects the sealing and service life of the equipment due to improper operation. Especially when replacing filter cartridges in an emergency, the cumbersome disassembly process will delay the maintenance opportunity, thereby reducing the water purification effect and even causing secondary pollution. Therefore, a technical solution that can quickly disassemble and assemble filter cartridges is needed to improve the convenience and efficiency of equipment maintenance. To this end, a direct drinking water purification device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a direct drinking water purification device, which aims to improve the problem that the traditional filter cartridge disassembly process in the prior art is cumbersome, requires tools, and is time-consuming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a direct drinking water purification device, comprising a main body, a filter cartridge connector fixedly connected to the bottom of the main body, a filter cartridge body disposed inside the filter cartridge connector, a water inlet pipe fixedly connected to the side wall of the main body, a quick-release assembly disposed inside the filter cartridge connector, and a connecting assembly disposed on the outer wall of the water inlet pipe;

[0007] The quick-release assembly includes a locking block and a locking hole formed on the outer wall of the filter cartridge body. The outer wall of the locking block is slidably connected to the inside of the filter cartridge connector. The locking block and the locking hole are engaged. A sealing ring is fixedly connected to the top of the filter cartridge body. A hollow block is fixedly connected to the outer wall of the filter cartridge connector. A sliding column is slidably connected inside the hollow block. One end of the sliding column is fixedly connected to the side wall of the locking block. A rotating column is rotatably connected inside the sliding column. A lever is fixedly connected to the outer wall of the rotating column. A spring is sleeved on the outer wall of the sliding column.

[0008] As a further description of the above technical solution:

[0009] One end of the spring is fixedly connected to the side wall of the card block, and the other end of the spring is fixedly connected to the inside of the hollow block.

[0010] As a further description of the above technical solution:

[0011] The connecting assembly includes a connecting pipe and a hollow cylinder. The outer wall of the connecting pipe is slidably connected to the inside of the water inlet pipe, and the inner wall of the hollow cylinder is slidably connected to the outer wall of the water inlet pipe.

[0012] As a further description of the above technical solution:

[0013] The hollow cylinder has a groove inside, and a retaining ball is slidably connected inside the groove.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the ball is slidably connected to the inside of the water inlet pipe, and the outer wall of the ball is slidably connected to the inside of the connecting pipe.

[0016] As a further description of the above technical solution:

[0017] A sealing ring is fixedly connected to one end of the connecting pipe, and a fixing ring is fixedly connected inside the hollow cylinder.

[0018] As a further description of the above technical solution:

[0019] A second spring is provided on the side wall of the fixed ring. One end of the second spring is fixedly connected to the side wall of the fixed ring, and the other end of the second spring is fixedly connected to the inside of the hollow cylinder.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by moving the lever, the sliding column and the locking block compression spring move together into the hollow block, causing the locking block to disengage from the locking hole. At this time, the filter cartridge can be quickly removed by pulling it down, achieving the effect of quick disassembly and assembly of the filter cartridge. This solves the problem that the traditional filter cartridge disassembly process is cumbersome, requires tools and is time-consuming, improves the convenience of equipment maintenance, and makes it easier for users to replace the filter cartridge in a timely manner to ensure the purification effect.

[0022] 2. In this utility model, the spring is compressed by sliding the hollow cylinder. At this time, the locking ball slides from the water inlet pipe into the groove. Then, the connecting pipe is inserted into the water inlet pipe. After releasing the hollow cylinder, the spring releases its elastic potential energy to drive the hollow cylinder to reset, so that the locking ball leaves the groove and simultaneously locks into the water inlet pipe and the connecting pipe. This achieves a quick and stable connection between the water inlet pipe and the connecting pipe, solving the problems of complicated operation, poor sealing performance and easy leakage of traditional pipe connection methods, and improving the convenience and sealing of pipe connection.

[0033] The quick-release assembly includes a locking block 9 and a locking hole 6 on the outer wall of the filter cartridge body 3. The outer wall of the locking block 9 is slidably connected to the inside of the filter cartridge connector 2. The locking block 9 and the locking hole 6 engage, and the filter cartridge body 3 is fixed through the engagement structure. A sealing ring 5 is fixedly connected to the top of the filter cartridge body 3 to prevent water leakage and ensure a sealed filtration process. A hollow block 7 is fixedly connected to the outer wall of the filter cartridge connector 2 to accommodate the sliding column 8 and provide guidance. The sliding column 8 is slidably connected inside the hollow block 7. The end is fixedly connected to the side wall of the locking block 9. The sliding column 8 is used to drive the locking block 9 to move to achieve unlocking. The sliding column 8 is rotatably connected to the rotating column 11. The outer wall of the rotating column 11 is fixedly connected to the toggle block 10. The toggle block 10 is used for manual operation to drive the rotating column 11 and the sliding column 8 to move. The outer wall of the sliding column 8 is fitted with a spring 12. One end of the spring 12 is fixedly connected to the side wall of the locking block 9, and the other end of the spring 12 is fixedly connected to the inside of the hollow block 7. The spring 12 is used to provide a reset spring force so that the locking block 9 automatically returns to its position and remains in the locked state.

[0034] Reference Figure 5 and Figure 6The connecting assembly includes a connecting pipe 13 and a hollow cylinder 14. The outer wall of the connecting pipe 13 is slidably connected to the inside of the water inlet pipe 4, and the connecting pipe 13 is used to connect with an external pipe. The inner wall of the hollow cylinder 14 is slidably connected to the outer wall of the water inlet pipe 4, and the hollow cylinder 14 is used to push the locking ball 16 to achieve locking and unlocking. A groove 15 is formed inside the hollow cylinder 14, which is used to temporarily accommodate the locking ball 16 so that the connecting pipe 13 can be inserted or pulled out. The locking ball 16 is slidably connected inside the groove 15, and the outer wall of the locking ball 16 is slidably connected to the inside of the water inlet pipe 4 and the connecting pipe 13. The ball 16 is used to lock the connecting tube 13 to prevent it from falling off. One end of the connecting tube 13 is fixedly connected to a sealing ring 17. The sealing ring 17 is used to ensure the sealing of the connection and prevent water leakage. A fixing ring 18 is fixedly connected inside the hollow cylinder 14. The fixing ring 18 is used to fix the spring 19. The fixing ring 18 is provided with a spring 19 on its side wall. One end of the spring 19 is fixedly connected to the side wall of the fixing ring 18, and the other end of the spring 19 is fixedly connected to the inside of the hollow cylinder 14. The spring 19 is used to provide a reset force so that the hollow cylinder 14 automatically returns to its original position and maintains the locked state of the ball 16.

[0035] Working Principle: The filter cartridge body 3 is secured by the locking block 9 and the locking hole 6 inside the filter cartridge connector 2, ensuring a stable installation. When the filter cartridge needs to be disassembled, the user only needs to move the lever 10, causing it to rotate the rotating column 11, which in turn pushes the sliding column 8 into the hollow block 7. The sliding column 8 drives the locking block 9 to compress the spring 12, causing the locking block 9 to disengage from the locking hole 6 and release the lock on the filter cartridge body 3. At this time, the filter cartridge body 3 can be pulled directly downwards for quick disassembly. During installation, simply push the filter cartridge body 3 upwards into the filter cartridge connector 2, release the lever 10, and the locking block 9 will automatically engage with the locking hole 6 under the elastic force of the spring 12, achieving quick fixation. The sealing ring 5 ensures the seal between the filter cartridge and the connector, preventing water leakage and avoiding the cumbersome operation of traditional threaded or snap-fit ​​disassembly, thus improving maintenance efficiency.

[0036] When connecting the water inlet pipe 4, the user first slides the hollow cylinder 14 backward to compress the second spring 19. At this time, the retaining ball 16 loses its restraint inside the water inlet pipe 4 and slides into the groove 15 of the hollow cylinder 14. Then, the connecting pipe 13 is inserted into the water inlet pipe 4. After it is in place, the hollow cylinder 14 is released, and the second spring 19 rebounds and pushes the hollow cylinder 14 to reset, causing the retaining ball 16 to slide out of the groove 15 and simultaneously lock into the corresponding grooves 15 of the water inlet pipe 4 and the connecting pipe 13, forming a mechanical lock. The second sealing ring 17 ensures the sealing of the connection and prevents leakage. When disassembling, simply slide the hollow cylinder 14 again to make the retaining ball 16 return to the groove 15, and the connecting pipe 13 can be easily pulled out. This simplifies the operation steps of traditional threaded or quick-connect couplings and improves the stability and sealing of the connection.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
