Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The following is combined with Figures 1 to 4 A dual-filter shower head according to an embodiment of the present utility model includes a handle 100 and a shower head 200 connected to the handle 100; a first filter element 101 is provided inside the handle 100, and the shower head 200 includes a housing 1, a water spray assembly 2, a second filter element 3 and a rear cover 4. The water spray assembly 2 is disposed on the front end face of the housing 1; The rear end of the housing 1 is recessed inward and has a filter chamber 5. The bottom of the filter chamber 5 is provided with a filter outlet 51. One end of the filter outlet 51 is connected to the water inlet of the water spray assembly 2. The second filter element 3 is disposed in the filter chamber 5. The other end of the filter outlet 51 is connected to the water outlet of the second filter element 3. The rear cover 4 is provided with a connecting ring 41. A plurality of snap-fit ​​blocks 42 are arranged circumferentially on the outer wall of the connecting ring 41. A plurality of snap-fit ​​grooves 52 are arranged circumferentially on the side wall of the filter chamber 5. When the rear cover 4 is installed in the filter chamber 5, the snap-fit ​​blocks 42 can be inserted into the corresponding snap-fit ​​grooves 52 respectively. The side wall of the filter chamber 5 is provided with a water inlet 53, which is connected to the water inlet end of the second filter element 3.

[0022] Specific working principle: Water first enters the handle 100 from the water supply pipe. The handle 100 contains a first filter element 101. The water flows through this filter element and undergoes preliminary filtration. This step is usually used to remove larger particles of impurities in the water, such as silt and rust. The water that has passed through the initial filtration flows out of the handle 100 and into the shower head 200. The water flows through the inlet 53 on the side wall of the filter chamber 5 into the filter chamber 5 located inside the shower head 200. The filter chamber 5 contains a second filter element 3. After entering through inlet 53, the water flows through the second filter element 3. The second filter element 3 typically uses more sophisticated filter materials, such as activated carbon, KDF, and vitamin balls, to remove residual chlorine, fine particles, some heavy metals, and odors from the water, achieving "fine filtration" and functional purification. The water, deeply purified by the second filter element 3, enters the filter outlet 51 located at the bottom of the filter chamber 5. The filter outlet 51 is directly connected to the inlet of the spray assembly 2. Finally, the clean water, after double filtration, is evenly sprayed out through the spray assembly 2. A rear cover 4 is designed for replacing the second filter element 3. The rear cover 4 uses a snap-fit ​​block 42 on its connecting ring 41 to rotate and engage with a snap-fit ​​groove 52 on the side wall of the filter chamber 5, enabling quick installation and removal.

[0023] This application combines two filter cartridges with different functions to achieve comprehensive purification of everything from physical impurities to chemical substances (such as residual chlorine), resulting in significantly better water quality than single-filter showerheads. The second filter cartridge 3 is cleverly embedded in the inwardly recessed filter chamber 5 at the rear end of the showerhead 200, making full use of the space within the showerhead 200 itself without significantly increasing the overall size of the showerhead, maintaining the product's streamlined and aesthetically pleasing appearance. The rotating locking design of the snap-fit ​​block 42 and snap-fit ​​groove 52 on the rear cover 4 makes replacing the second filter cartridge 3 extremely convenient. Users do not need tools; simply rotating the rear cover 4 is sufficient to remove and replace the second filter cartridge 3. Installation is also as simple as rotating the rear cover, greatly improving the product's ease of use and maintenance. This design also avoids problems such as stripped threads, insufficient tightening, or over-tightening that can prevent opening when using threaded connections.

[0024] Furthermore, the snap-fit ​​groove 52 is arranged in a direction perpendicular to the axis of the filter chamber 5, and a guide angle 54 is provided at the opening of the snap-fit ​​groove 52. When the rear cover 4 is installed in the filter chamber 5, the snap-fit ​​block 42 is inserted into the corresponding snap-fit ​​groove 52 by rotating and along the guide angle 54.

[0025] Specifically, the guide angle 54 is usually an inclined or arc-shaped surface. At the moment the locking block 42 contacts the opening of the locking groove 52, it guides and corrects misalignment. Even if the rear cover 4 and the filter chamber 5 are initially misaligned, under rotational pressure, the locking block 42 will automatically slide into the locking groove 52 along the guide angle 54, thus achieving easy installation. Users do not need to painstakingly find precise locking points, making operation more convenient and faster. Traditional threaded connections require many turns with a screwdriver bit and are easily damaged due to misaligned threads. With this design, users only need to place the rear cover 4 on top and gently twist the locking block 42 to easily slide it into the locking groove 52 for installation. This process is extremely quick and effortless.

[0026] Furthermore, the connecting ring 41 is sleeved on the outer periphery of the second filter element 3, and the side wall of the connecting ring 41 is provided with a water inlet hole 43, which is connected to the water inlet 53 of the filter chamber 5. The inner side of the rear cover 4 is provided with a plurality of suspended ribs 44, and a suspended cavity 45 is formed between the suspended ribs 44. The water inlet 43 is connected to the suspended cavity 45, and the suspended cavity 45 is connected to the water inlet end of the second filter element 3.

[0027] Specifically, water enters through a single inlet 53 on the side wall of the filter chamber 5, first passing through the inlet hole 43 on the side wall of the connecting ring 41, and then entering the suspended cavity 45 formed by the suspended ribs 44. The suspended cavity 45 surrounds the entire outer circumference of the inlet end of the second filter element 3. This allows the water flow to penetrate evenly from the entire circumferential surface of the filter element, rather than impacting the filter element from one point or one direction. The suspended cavity 45 forms an annular pressure stabilizing chamber before the inlet end of the filter element, where the water flow can temporarily stabilize and balance the pressure. This avoids excessively fast local water flow and excessive pressure, making the water flow to the filter element more stable and preventing uneven water output from the spray assembly 2. Uniform water distribution also ensures that all the filter media inside the second filter element 3 is fully utilized, thereby significantly improving the filtration efficiency and extending the actual service life of the filter element.

[0028] Furthermore, a rotating paddle 46 is provided on the outer side of the rear cover 4.

[0029] Specifically, the rear cover 4 is usually a smooth curved surface, especially after it becomes wet and slippery, making it difficult for users to apply force and rotate it smoothly to install or remove it. The rotating paddle 46 provided in this embodiment directly provides a clear point of force application. Users can naturally hold and push the paddle with their fingers, thereby easily applying rotational torque to rotate the rear cover 4 to complete the installation and removal, making the operation more convenient and faster.

[0030] Furthermore, the second filter element 3 includes a filter element shell 31, a first filter screen 32, a filter media 33, a second filter screen 34, and a filter element cover 35; the filter element cover 35 is used to seal the opening of the filter element shell 31. The filter cartridge 31 is provided with a water outlet hole, and the first filter screen 32 is disposed inside the water outlet hole. The filter cover 35 is provided with a plurality of filter inlet holes, and the second filter screen 34 is disposed inside the filter inlet holes; The filter media 33 is disposed between the first filter screen 32 and the second filter screen 34.

[0031] Specifically, water enters through the hollow cavity 45 of the rear cover 4, first passing through the filter inlet hole on the filter element cover 35. The water then passes through the second filter screen 34, which intercepts any larger particles that may enter. The water then enters the enclosed space formed by the first filter screen 32 and the second filter screen 34, making full contact with the filter media 33. The filter media 33, such as activated carbon, KDF, water softening resin, and vitamin balls, plays a crucial purification role in this process, adsorbing residual chlorine, heavy metals, odors, or releasing minerals. The first filter screen 32 prevents fine particles or potentially detached substances from the filter media 33 from flowing out with the water. Finally, clean water flows out through the filter outlet holes on the filter cartridge shell 31 and enters the spray assembly 2 of the shower head. By setting two physical barriers, the pre-filter second screen 34 and the post-filter first screen 32, and sealing the core filter media 33 in the middle, the internal filter media 33 is protected from the impact and contamination of large particles from the water inlet. This prevents the filter media 33 from being lost downstream due to water flow erosion or its own wear during long-term use, thus avoiding clogging the precision spray holes of the shower head. The dual filter structure together firmly fixes the filter media 33 inside the filter cartridge shell 31, ensuring the structural integrity and reliability of the filter cartridge during transportation, installation, and use.

[0032] Designing the second filter element 3 as an independent, fully functional module allows it to be mass-produced and managed as a standard component. For users, replacing the filter element becomes incredibly simple: only the entire second filter element 3 module needs to be replaced, eliminating the need to access its complex internal structure. This typical plug-and-play maintenance greatly enhances the user experience.

[0033] Furthermore, the inner wall of the rear side of the housing 1 is provided with a snap-fit ​​groove 11, and the edge of the water spray assembly 2 is provided with a snap-fit ​​block 231. When the water spray assembly 2 is installed on the housing 1, the snap-fit ​​block 231 is snapped into the snap-fit ​​groove 11.

[0034] Specifically, when installing the water spray assembly 2, align it with the mounting position at the front end of the housing 1. By pressing, the snap-fit ​​block 231 on the edge of the water spray assembly 2 undergoes slight elastic deformation and slides into the corresponding snap-fit ​​groove 11 on the inner wall of the housing 1. When the snap-fit ​​block 231 is fully inserted into the snap-fit ​​groove 11, it will return to its shape due to the elasticity of the material itself and form a mechanical interlock with the snap-fit ​​groove 11, thereby firmly fixing the water spray assembly 2 to the housing 1. The operation is simple and convenient, which can greatly shorten the assembly time, reduce labor costs, and improve work efficiency. The snap-fit ​​connection eliminates the need for additional fasteners such as screws, nuts, and washers, which directly reduces the types and quantities of materials and further reduces costs.

[0035] Furthermore, the water spray assembly 2 includes a nozzle top cover 21, a silicone water outlet block 22, and a nozzle bottom cover 23. The nozzle top cover 21 has a positioning groove 211 at its edge, and the nozzle bottom cover 23 has a positioning protrusion 232 at its edge. When the nozzle top cover 21 is closed onto the nozzle bottom cover 23, the positioning protrusion 232 is positioned within the positioning groove 211. The silicone water outlet block 22 is disposed between the nozzle top cover 21 and the nozzle bottom cover 23.

[0036] Specifically, the silicone water outlet block 22 is the core component, densely covered with tiny water outlet holes responsible for forming water jets or splashes. The nozzle lower cover 23 serves as the base and is usually connected to the water inlet passage. The nozzle upper cover 21 serves as the panel and usually faces the user, with holes that allow the water jet to pass through. Through the cooperation of the positioning protrusion 232 and the positioning groove 211, the upper and lower covers can be quickly and accurately aligned when they are fastened together, thus firmly and flatly pressing the silicone water outlet block 22 between them. The positioning protrusion 232 and the positioning groove 211 constitute a positioning system, thereby ensuring the precise positioning and alignment of all water outlet channels, allowing the water to spray out without obstruction and ensuring the water output effect.

[0037] Furthermore, the nozzle lower cover 23 is provided with a plurality of positioning circular grooves 233, and the silicone water outlet block 22 is provided with a plurality of positioning columns 221. When the silicone water outlet block 22 is installed on the nozzle lower cover 23, the positioning columns 221 are respectively inserted into the positioning circular grooves 233.

[0038] Specifically, silicone material is soft and easily deformed. If it is not restrained during assembly, it can easily slide or twist between the upper and lower covers of the nozzle, causing the water outlet micro-holes on it to misalign with the water outlet holes on the upper and lower covers, thus affecting the water output effect or even completely clogging it. In this embodiment, the positioning column 221 is inserted into the positioning groove 233 to form a precise tenon and mortise structure, ensuring that the silicone water outlet block 22 is completely fixed in the horizontal direction and cannot move, thereby ensuring the precise alignment of all water outlet channels and thus ensuring the water output effect.

[0039] Furthermore, a handle connector 300 is provided at the water inlet end of the housing 1. The handle connector 300 is ultrasonically welded to the housing 1, and the handle 100 is threadedly connected to the handle connector 300.

[0040] Specifically, the handle connector 300 is permanently fixed to the water inlet end of the housing 1 by ultrasonic welding. The ultrasonic welding forms a molecular-level, seamless permanent seal between the housing 1 and the handle connector 300. The handle 100 is screwed onto the fixed handle connector 300 by threaded connection, making it simpler and more convenient for users to operate.
