[0031] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0032] like Figures 1-6 As shown, a direct drinking water terminal disinfection device of this application includes an inlet 1, a quick-release filter cartridge 2, a disinfection module 3, a sealing connection structure 4, and an outlet 5. The inlet 1 is used to receive water to be treated, and is typically located at the front end of the device, connected to an external water source via a pipe to provide a channel for water to enter the device. The design of the inlet 1 must ensure airtightness while also allowing for a stable connection with the subsequent quick-release filter cartridge 2.

[0033] The quick-release filter element 2 is connected to the water inlet 1 and serves as a preliminary filter for the water, mainly responsible for removing suspended particles, silt, and other larger impurities. This filter element is usually an independent component with a certain volume, and is installed after the water inlet 1. Its structure generally includes a filter media layer and a shell, and can be detachably connected to subsequent components by screwing or snapping.

[0034] The disinfection module 3 is connected to the quick-release filter element 2 and is used to disinfect the filtered water with ultraviolet light, thereby killing bacteria, viruses, and other microorganisms that may be present in the water. This module typically contains an ultraviolet lamp and a corresponding circuit control system. It is installed after the quick-release filter element 2 and maintains a good seal with the filter element through a sealing connection structure 4.

[0035] The sealing connection structure 4 is disposed between the quick-release filter element 2 and the disinfection module 3. Its function is to provide a detachable sealed connection to ensure that water does not leak when passing through the connection between the two. This structure consists of a sealing ring 41, a snap-fit ​​mechanism 42, and a locking ring 43. The components work together to ensure that the device maintains a seal while providing good ease of maintenance.

[0036] The sealing ring 41 is disposed between the outlet end of the quick-release filter element 2 and the inlet end of the disinfection module 3, serving as the main sealing element to ensure that water does not leak outwards or inwards at this location. It is typically made of rubber or silicone material, possessing a certain degree of elasticity and weather resistance, enabling it to adapt to working conditions in different environments, while also facilitating replacement and maintenance.

[0037] The latching mechanism 42 detachably connects the quick-release filter element 2 and the disinfection module 3, enabling rapid locking and unlocking operations. This allows users to separate the components without tools when replacing the filter element or performing maintenance. The latching mechanism 42 is typically made of metal or plastic, and its structural design usually employs a combination of elastic claws and a fixing seat. The latching is triggered by pressing or rotating, improving installation efficiency.

[0038] The locking ring 43 is sleeved on the outside of the latching mechanism 42, serving to fix the axial position of the latching mechanism 42 and prevent the connection from becoming loose due to vibration or accidental contact. The locking ring 43 is usually a circular component that can slide and adjust along the axial direction, forming a mechanical lock with the latching mechanism 42 and enhancing the overall stability of the connection.

[0039] The features described in this application improve the ease of maintenance of the device by incorporating a quick-release filter element 2 and a disinfection module 3 with a sealing connection structure 4. The detachable connection method, achieved through the snap-fit ​​mechanism 42 and locking ring 43, allows users to replace the filter element or inspect the disinfection module 3 manually without the need for complex disassembly tools. Simultaneously, the sealing connection structure 4 ensures a tight seal at the connection point, preventing leakage caused by frequent disassembly and reassembly. The combination of these technical measures not only improves user convenience but also enhances the overall reliability and service life of the device.

[0040] like Figure 4 and Figure 6As shown, in one embodiment, the sealing connection structure 4 of the direct drinking water terminal disinfection device of this application further includes a guide pin 44, which is disposed between the outlet end of the quick-release filter element 2 and the inlet end of the disinfection module 3. The function of the guide pin 44 is to ensure that the quick-release filter element 2 and the disinfection module 3 can be accurately connected during installation, reducing assembly errors and improving the overall installation efficiency and reliability. With the assistance of the guide pin 44, sealing failure or component damage caused by improper installation can be effectively prevented.

[0041] Specifically, the guide pin 44 can be designed with one end fixed to the outer edge of the quick-release filter element 2 and the other end embedded in the inner wall groove of the disinfection module 3. When the two are connected, the guide pin 44 slides along the groove and guides them to fit correctly. This structure can be formed by machining or casting, and together with the snap-fit ​​mechanism 42 and the locking ring 43, it can achieve a stable connection and precise alignment between the quick-release filter element 2 and the disinfection module 3.

[0042] In one embodiment, the sealing ring 41 of the direct drinking water terminal disinfection device of this application is made of silicone material, which has high elasticity and wear resistance, making it easy to restore to its original shape after disassembly and reducing the risk of leakage. The sealing ring 41 is located between the outlet end of the quick-release filter cartridge 2 and the inlet end of the disinfection module 3. Through its good elasticity and wear resistance, it maintains a tight fit during repeated disassembly and assembly, ensuring the sealing effect of the connection. At the same time, its flexibility makes it less prone to deformation or damage during installation and disassembly, improving ease of use and stability. Furthermore, this material has certain temperature resistance and anti-aging properties, enabling it to maintain good sealing performance under different environmental conditions.

[0043] Specifically, the sealing ring 41 is manufactured using a one-piece molding process and is embedded between the connecting end faces of the quick-release filter element 2 and the disinfection module 3, forming a radial compression sealing structure. The surface of the sealing ring 41 is smoothed to ensure a good seal with the contact surface. Positioning grooves are provided on both sides to guide alignment and fixation during installation, preventing misalignment or displacement. During use, the snap-fit ​​mechanism 42 and the locking ring 43 work together to keep the sealing ring 41 under stable pressure, further enhancing the sealing effect.

[0044] like Figure 4 and Figure 6As shown, in one embodiment, the sealing connection structure 4 of the direct drinking water terminal disinfection device of this application includes a sealing ring 41. The sealing ring 41 is disposed between the outlet end of the quick-release filter element 2 and the inlet end of the disinfection module 3 to achieve a watertight seal between the two. The position of the sealing ring 41 is defined within the annular groove 45 of the quick-release filter element 2. The structure of the groove positions the sealing ring 41, preventing it from shifting or falling off during installation or disassembly, thereby ensuring stable sealing performance. At the same time, the annular groove 45 can also effectively enhance the stability of the sealing ring 41 and improve the durability of the overall structure.

[0045] For example, the outlet end of the quick-release filter element 2 is provided with an annular groove 45, and the sealing ring 41 is embedded in the groove and closely attached to the inlet end face of the disinfection module 3. The groove forms a physical constraint on the sealing ring 41, preventing it from sliding or falling off due to force during disassembly and assembly, thereby ensuring the reliability of the sealing connection. The snap-fit ​​mechanism 42 and the locking ring 43 work together to achieve a detachable and stable connection between the quick-release filter element 2 and the disinfection module 3.

[0046] like Figure 4 and Figure 6 As shown, in one embodiment, the latching mechanism 42 of a direct drinking water terminal disinfection device of this application includes a plurality of circumferentially distributed latching claws 46. Each latching claw 46 is elastically deformable to provide a uniform locking force during the connection process, thereby ensuring that the sealed connection structure 4 is stable and reliable after installation, while reducing the force required for unlocking and improving operational convenience. The latching claws 46 are disposed at the connection between the quick-release filter element 2 and the disinfection module 3, and achieve quick assembly and disassembly through elastic deformation, avoiding sealing failure or loosening of the connection due to uneven force.

[0047] Specifically, the snap-fit ​​claws 46 are installed on the outer wall of the sealing connection structure 4 in a ring shape. One end of each snap-fit ​​claw 46 is fixed to the main body of the sealing connection structure 4, and the other end extends outward and has an elastic bending portion, so that the snap-fit ​​claw 46 can deform under external force, thereby realizing the snap-fit ​​connection between the disinfection module 3 and the quick-release filter element 2. During installation, the snap-fit ​​claws 46 deform under external pressure and return to their original shape after being in place, locking the two components together.

[0048] like Figure 4As shown, in one embodiment, the sealing connection structure 4 of a direct drinking water terminal disinfection device of this application includes a snap-fit ​​claw 46, the end of which is provided with a bevel 47. The bevel 47 facilitates the guiding of the quick-release filter cartridge 2 and the disinfection module 3 during the connection process, ensuring smooth docking. The bevel 47 design allows the user to achieve automatic engagement between components without excessive angle adjustments during installation, thus reducing operational difficulty. The snap-fit ​​claw 46, through its structural characteristics, cooperates with the locking ring 43 to ensure the stability of the sealed connection, while also facilitating subsequent disassembly and maintenance.

[0049] Specifically, the latching claw 46 is mounted on the latching mechanism 42, with its end extending into an inclined surface 47. This inclined surface 47 is located at the connection between the outlet end of the quick-release filter element 2 and the inlet end of the disinfection module 3. When the two components come into contact, the inclined surface 47 cooperates with the edge of the other, guiding and gradually pressing the latching claw 46 to complete the closing action, thereby achieving the locking of the sealed connection structure 4.

[0050] like Figure 4 As shown, in one embodiment, the locking ring 43 of a direct drinking water terminal disinfection device of this application includes a release button 48. The release button 48 is disposed on the outer surface of the locking ring 43 for one-button unlocking of the latching mechanism 42, improving disassembly convenience. The design of the release button 48 allows users to quickly disassemble the device without tools, facilitating maintenance or component replacement. The locking ring 43 is sleeved on the outside of the latching mechanism 42, and its structural design axially positions and fixes the latching mechanism 42, ensuring the stability of the sealed connection structure 4 during use. The latching mechanism 42 is detachably connected to the quick-release filter element 2 and the disinfection module 3, while the locking ring 43 serves to reinforce and lock, ensuring reliable overall connection and convenient operation.

[0051] Specifically, the release button 48 is connected to the latching mechanism 42 via a mechanical linkage. When the user presses the release button 48, it causes the locking component inside the latching mechanism 42 to shift, releasing the locking state between the quick-release filter element 2 and the disinfection module 3. The locking ring 43 is installed on the periphery of the latching mechanism 42 and has a guide groove or protrusion structure inside. It forms a fitting fit with the outer side of the latching mechanism 42, thereby restricting its axial movement and keeping the latching mechanism 42 in a locked state when the release button 48 is not triggered.

[0052] like Figure 4As shown, in one embodiment, the locking ring 43 of the direct drinking water terminal disinfection device of this application has a thread 49 on its inner circumference. This thread 49 engages with the thread 49 on the outer circumference of the snap-fit ​​mechanism 42, achieving axial fixing and unlocking through rotation. This structural design allows the user to fix or disassemble the sealing connection structure 4 by rotating the locking ring 43 with one hand, improving ease of use. Simultaneously, this connection method effectively prevents accidental loosening due to external forces, ensuring the stability and sealing of the device during use.

[0053] Specifically, the locking ring 43 is sleeved on the outside of the snap-fit ​​mechanism 42 via a threaded structure 49, and the threaded relationship 49 is set between the inner wall of the locking ring 43 and the outer wall of the snap-fit ​​mechanism 42. When the locking ring 43 is rotated, the thread 49 on its inner wall engages with the thread 49 on the outer wall of the snap-fit ​​mechanism 42, pushing the snap-fit ​​mechanism 42 to move axially, thereby fixing it in the installation position between the quick-release filter element 2 and the disinfection module 3.

[0054] like Figure 4 As shown, in one embodiment, the quick-release filter cartridge 2 of the direct drinking water terminal disinfection device of this application is provided with an external thread 50 at its outlet end. This external thread 50 is used to achieve a detachable fastening engagement with the internal thread 51 of the snap-fit ​​mechanism 42. The engagement of the external thread 50 and the internal thread 51 ensures a secure connection between the quick-release filter cartridge 2 and the snap-fit ​​mechanism 42, while also facilitating quick disassembly and replacement when needed. This design improves the ease of operation and maintenance efficiency of the device during use.

[0055] Specifically, the outlet end of the quick-release filter element 2 is machined with an external thread 50, while the snap-fit ​​mechanism 42 has a matching internal thread 51. When the two are screwed together, the external thread 50 and the internal thread 51 form a stable and reliable threaded connection 49. This connection method not only ensures sealing but also allows for quick assembly and disassembly through rotation, thereby enhancing the practicality and flexibility of the overall structure.

[0056] like Figure 3 and Figure 5 As shown, in one embodiment, the inlet end of the disinfection module 3 of the direct drinking water terminal disinfection device of this application is provided with an internal thread 51. The internal thread 51 is located at the connection position between the disinfection module 3 and the quick-release filter element 2, and is used to form a thread 49 engagement with the snap-fit ​​mechanism 42. The internal thread 51 enables the snap-fit ​​mechanism 42 to be firmly fixed on the disinfection module 3, improving the sealing and stability of the overall structure. This design facilitates maintaining the consistency of the interface during installation and disassembly, and effectively prevents the connection from loosening due to vibration or external force.

[0057] For example, the inlet end of the disinfection module 3 is machined with an internal thread 51, while one end of the snap-fit ​​mechanism 42 is provided with an external thread 50 that matches the internal thread 51. By screwing the snap-fit ​​mechanism 42 into the internal thread 51 of the disinfection module 3, a tight connection between the two is achieved, ensuring that water flow will not leak during operation, while also supporting quick loading and unloading.

[0058] In one embodiment, the inlet 1 of a direct drinking water terminal disinfection device of this application is connected to a quick-release filter element 2 via a quick connector 52 to achieve convenient connection and disassembly. The quick connector is located at the outlet end of the inlet 1 and connects to the inlet end of the quick-release filter element 2, ensuring unobstructed water flow and reliable sealing. The quick connector design facilitates tool-free operation, allowing users to replace the filter element without any tools, thereby improving the ease of use of the device. Simultaneously, the connection structure between the quick connector and the quick-release filter element 2 ensures stable fluid transmission and reduces the risk of seal failure due to frequent disassembly and reassembly.

[0059] In one embodiment, the outlet end of the inlet 1 is provided with an external thread 50, while the inlet end of the quick-release filter element 2 is provided with an internal thread 51. The two are initially fixed by the engagement of the threads 49. Based on the engagement of the threads 49, the quick connector is provided with an elastic clamping component inside, which uses spring force to make the connector and the filter element fit tightly, ensuring stable water flow and no leakage. At the same time, the quick connector surface is provided with a guide bevel 47 to guide the filter element to be smoothly inserted and complete the sealing connection, improving installation efficiency.

[0060] In one embodiment, the water outlet 5 of a direct drinking water terminal disinfection device of this application is connected to the disinfection module 3 via a quick connector 53, which simplifies maintenance operations. The water outlet 5 and the disinfection module 3 are detachably connected, facilitating quick separation and assembly during daily use or maintenance. This connection structure enables convenient operation without affecting the overall sealing performance, reducing the difficulty of equipment maintenance. Simultaneously, this design helps improve the overall durability and ease of use of the device.

[0061] Specifically, the quick connector includes a female and a male body that match each other. The female body is fixedly installed at the end of the outlet 5, and the male body is connected to the inlet end of the disinfection module 3. The two are fixed by external thread 50 and are equipped with an anti-rotation structure to prevent rotation and loosening, ensuring a stable and reliable connection.

[0062] In actual operation, when this device is in use, the water to be treated enters the device through the inlet 1, and then passes through the quick-release filter element 2 for filtration to remove impurities. The filtered water flows into the disinfection module 3, where it is disinfected by ultraviolet irradiation. The disinfected water is discharged through the outlet 5. During the water flow, the sealing ring 41 in the sealing connection structure 4 ensures the water tightness between the components. At the same time, the buckling mechanism 42 and the locking ring 43 cooperate to keep the quick-release filter element 2 and the disinfection module 3 in a stable and detachable connection, which is convenient for daily cleaning and replacement.
