Description

Technical Field

[0001] This invention relates to the field of water purification device technology, and more specifically, to a quick-release membrane housing assembly for a water purifier. Background Technology

[0002] Against the backdrop of the booming development of water treatment technology, reverse osmosis membranes have become the core component of water purifiers due to their excellent filtration capabilities. The membrane housing that is matched with it plays a key role in achieving precise control and conduction of water flow. The ease of disassembling and assembling the membrane housing directly affects the efficiency of filter replacement and the user experience. Although many water purifier membrane housings on the market focus on quick-release function in their research and development, the existing technical solutions have many problems.

[0003] Currently, the installation and disassembly processes of some general-purpose membrane housings are cumbersome, often requiring specialized tools. Furthermore, the difficulty in uniformly tightening the threads during installation can lead to water leakage at the connections. Additionally, their inlet layout is often unreasonable, resulting in cluttered water circuits and inconvenient filter removal. Some specialized quick-connect membrane housings use a clamp-type quick-installation structure, which simplifies operation and reduces costs, but suffers from drawbacks such as easy wear of the clamp positioning structure and the need for manual alignment during installation and disassembly, which is prone to errors. Other rotary connection quick-installation structures, while efficient and easy to operate, have a concentrated inlet layout that can cause water source confusion, posing a risk of water contamination. Therefore, we propose a quick-release membrane housing assembly for water purifiers. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick-release membrane housing assembly for a water purifier to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-release membrane housing assembly for a water purifier, comprising a filter bottle, a water circuit connection structure on the top of the filter bottle, an inlet buckle, a clean water outlet buckle and a drain outlet buckle respectively on the top of the water circuit connection structure, an inlet check valve, a clean water check valve, a check structure and a drain check valve respectively on the bottom of the water circuit connection structure, an RO membrane filter element installed inside the filter bottle for filtering the incoming water, and a rotating connection structure, a fixing block and a fixing connection structure respectively on the top of the filter bottle for quick connection and sealing between the filter bottle and the water circuit connection structure; The waterway connection structure is equipped with a corresponding positioning boss; The fixing block is equipped with a connecting buckle and a positioning groove, which cooperate with the positioning boss on the water connection structure. It is installed by rotation for automatic alignment and fixation. The fixed connection structure is equipped with water inlet, water outlet, clean water outlet, and sewage outlet, which are used in conjunction with the rotary connection structure for connecting and isolating water channels.

[0006] Preferably, the inlet buckle, the clean water outlet buckle, and the drain buckle are fixedly connected to the inlet pipe, clean water pipe, and drain pipe of the external water system through buckle connection.

[0007] Preferably, the inlet check valve, the purified water check valve, and the drain check valve are pressed onto the water circuit connection structure by a check structure and sealed by O-rings to prevent water leakage.

[0008] Preferably, the inlet check valve, the purified water check valve, the check structure, and the drain check valve are used to control the unidirectional flow of water.

[0009] Preferably, the rotary connection structure is used to isolate the water inlet, the purified water, and the sewage outlet.

[0010] Preferably, the water purifier outlet is independently connected to an external water purifier pipe via a water purifier outlet clip.

[0011] Preferably, the water inlet, water outlet, purified water outlet, and sewage outlet on the fixed connection structure are respectively matched with the rotary connection structure for water inlet, filtration, purified water output, and sewage discharge water flow.

[0012] Preferably, the rotary connection structure and the fixed connection structure are sealed at the end face by an O-ring to prevent water leakage at the connection.

[0013] Preferably, the filter bottle is installed by rotating it upwards, so that the connecting buckle of the fixing block is engaged with the inner wall of the water connection structure for installing and fixing the filter bottle.

[0014] The technical effects and advantages of this invention are as follows: 1. In use, the quick-release membrane housing assembly of this water purifier adopts a rotating snap-on quick-installation structure, which greatly simplifies the installation and disassembly process of the filter bottle. Users only need to rotate the filter bottle upwards to install it, so that the connecting buckle of the fixing block snaps into the inner wall of the water circuit connection structure to achieve initial fixation of the filter bottle. At the same time, the positioning protrusion on the water circuit connection structure automatically aligns with the positioning groove of the fixing block, ensuring the accuracy and stability of the installation. This design does not require special tools and is simple and quick to operate. Even non-professional users can easily replace the filter element, greatly improving the efficiency of disassembly and assembly and bringing users a more convenient user experience.

[0015] 2. In use, this invention achieves effective isolation and precise connection of the three water paths—inlet, purified water, and sewage discharge—through the tight cooperation of the rotary connection structure and the fixed connection structure. The inclusion of inlet check valves, purified water check valves, and sewage discharge check valves ensures that water flows in only one direction, preventing backflow and contamination. Simultaneously, all connections are sealed with O-rings, effectively preventing water leakage and improving the overall structural stability and reliability. Furthermore, the rotary connection structure and the fixed connection structure are also sealed at the end face with O-rings, further enhancing the connection's stability and ensuring the water purifier's stable operation during long-term use, providing users with a safer and more reliable water purification service.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] As attached Figures 1-5The illustrated quick-release membrane housing assembly for a water purifier includes a filter bottle 12. A water connection structure 4 is located on the top of the filter bottle 12. The top of the water connection structure 4 is equipped with an inlet clip 1, a purified water outlet clip 2, and a drain outlet clip 3. These clips are fixedly connected to the inlet pipe, purified water pipe, and drain pipe of an external water system via clip connections. The purified water outlet provides an independent output and connects to an external purified water pipe via the purified water outlet clip 2. The bottom of the water connection structure 4 is equipped with an inlet check valve 5, a purified water check valve 6, a check structure 7, and a drain check valve 8. These check valves are pressed against the water supply by the check structure 7. The filter bottle 12 is equipped with a water circuit connection structure 4 and is sealed with an O-ring to prevent water leakage. The inlet check valve 5, the purified water check valve 6, the check structure 7, and the drain check valve 8 are used to control the unidirectional flow of water. The filter bottle 12 is equipped with an RO membrane filter element 13 to filter the inlet water. The top of the filter bottle 12 is equipped with a rotary connection structure 9, a fixed pressure block 10, and a fixed connection structure 11 to achieve quick connection and sealing between the filter bottle 12 and the water circuit connection structure 4. The rotary connection structure 9 is used to isolate the inlet water, purified water, and drain water. The rotary connection structure 9 and the fixed connection structure 11 are sealed at the end face with an O-ring to prevent water leakage at the connection. The waterway connection structure 4 is provided with a corresponding positioning boss 4-1; The fixing block 10 is provided with a connecting buckle 10-1 and a positioning groove 10-2, which cooperate with the positioning boss 4-1 on the water connection structure 4. It is used for automatic alignment and fixing by rotating installation. The filter bottle 12 is installed upward by rotating, so that the connecting buckle 10-1 of the fixing block 10 is inserted into the inner wall of the water connection structure 4 for the installation and fixing of the filter bottle 12. The fixed connection structure 11 is provided with an inlet hole 11-1, an outlet hole 11-2, a clean water hole 11-3, and a drain hole 11-4, which cooperate with the rotary connection structure 9 for connecting and isolating water circuits. The inlet hole 11-1, outlet hole 11-2, clean water hole 11-3, and drain hole 11-4 on the fixed connection structure 11 cooperate with the rotary connection structure 9 to form a water circuit process of water intake, filtration, clean water output, and drain.

[0024] The quick-release membrane housing assembly of this water purifier is mainly divided into two parts. The first part is the water circuit connection structure 4, which has an inlet buckle 1, a purified water inlet buckle 2, and a drain buckle 3 on its top. These three buckles are fixedly connected to the inlet pipe, purified water pipe, and drain pipe of the external water circuit through buckle connection to ensure stable water circuit access. At the same time, the bottom of the water circuit connection structure 4 is equipped with an inlet check valve 5, a purified water check valve 6, a check structure 7, and a drain check valve 8. These check valves are tightly pressed onto the water circuit connection structure 4 by the check structure 7 and sealed by O-rings to effectively prevent water leakage. The second part is the filter bottle 12 as the main body, which is equipped with an RO membrane filter element 13, which is the core component for filtering the incoming water. The top of the filter bottle 12 is equipped with a rotating connection structure 9, a fixed pressure block 10 and a fixed connection structure 11. These components work together to achieve quick connection and sealing between the filter bottle 12 and the water circuit connection structure 4.

[0025] The working principle of this invention is as follows: When installing the filter bottle 12, a rotating snap-fit ​​quick-installation structure is adopted. The filter bottle 12 is installed by rotating upwards, so that the connecting snap 10-1 of the fixing block 10 is snapped into the inner wall of the water channel connection structure 4, thus achieving the initial fixation of the filter bottle 12. At the same time, the positioning boss 4-1 on the water channel connection structure 4 automatically aligns with the positioning groove 10-2 of the fixing block 10. This design ensures the accuracy and stability of the installation. With the filter bottle 12 installed, the rotating connection structure 9 simultaneously connects the water path between the first and second parts. The water inlet of the first part is aligned with the water inlet hole 11-1 of the fixed connection structure, the clean water outlet is aligned with the clean water hole 11-3 of the fixed connection structure, and the sewage outlet is aligned with the sewage outlet 11-4 of the fixed connection structure. All connections are sealed with O-rings to ensure smooth water flow and no leakage. The rotating connection structure 9 effectively isolates the three water paths of water inlet, clean water, and sewage outlet, ensuring the independence and stability of each water path. The inlet check valve 5, the purified water check valve 6, and the drain check valve 8 play a crucial role in controlling the direction of water flow. When the water circuit is connected, water enters through the inlet pipe into the inlet latch 1, and then reaches the inlet check valve 5. The inlet check valve 5 ensures that water can only flow in one direction, preventing backflow. Subsequently, the water flows through the rotating connection structure 9 into the inlet hole 11-1, and then through the outlet hole 11-2 into the filter bottle 12. Inside the filter bottle 12, water enters from the bottom of the RO membrane filter element 13, and after fine filtration by the RO membrane, purified water flows out from the purified water hole 11-3. The purified water check valve 6 ensures that purified water can only flow out in one direction, preventing contamination. Finally, the purified water enters the purified water pipe through the purified water outlet latch 2 for user use. Wastewater generated during the filtration process flows out through drain hole 11-4. The wastewater then enters drain check valve 8 via rotary connection structure 9. Drain check valve 8 ensures that wastewater can only be discharged in one direction, preventing backflow contamination. Finally, the wastewater enters drain pipe through drain outlet buckle 3 and is discharged outside the system. The rotary connection structure 9 and the fixed connection structure 11 are sealed at the end face by an O-ring. This design effectively prevents water leakage at the connection and improves the stability and reliability of the overall structure. At the same time, the fixed pressure block 10 tightly presses the rotary connection structure 9 and the fixed connection structure 11 together, further enhancing the stability of the connection.
