Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a comprehensive filter element with water-saving function. Background Technology

[0002] The shower filter is one of the core components of a showerhead, and its performance directly affects the cleanliness of the shower water and the user's showering experience. However, current showerheads on the market have the following shortcomings in their filter design:

[0003] 1. In existing showerheads, water typically flows directly through the filter cartridge from the inlet hose. When the water pressure is high, the excessively fast flow rate may lead to insufficient filtration, reducing the purification effect of the filter cartridge and affecting the water quality. Furthermore, traditional showerheads lack effective water flow buffering or water-saving structures, which can easily cause an increase in water output when the water pressure is high, resulting in water waste and being detrimental to energy conservation and environmental protection.

[0004] 2. Most existing showerheads use a split design, with the showerhead handle divided into two parts. During installation, the filter and inlet hose need to be installed separately on the showerhead handle, which is cumbersome. Furthermore, the split showerhead handle not only increases manufacturing costs but may also lead to leaks due to thread wear after prolonged use, affecting the user experience.

[0007] The filter element is installed on the filter body. The filter body has a water passage cavity. One end of the water passage cavity is an open end and the other end is a closed end. The water passage kit is installed in a detachable manner on the open end of the water passage cavity. The water passage kit has several water passage holes that connect to the water passage cavity.

[0008] In the preferred embodiment, the shower handle is provided with a water inlet and a water passage connecting the water inlet.

[0009] In a preferred embodiment, the filter element body is cylindrical, and the filter element body has a diameter reduction section at the open end of the water passage cavity. The size of the water passage kit matches the size of the diameter reduction section of the filter element body.

[0010] In a preferred embodiment, the water-passing kit is cylindrical, and the diameter of the water-passing kit is larger than the diameter of the diameter reduction section of the filter element body. An opening is formed at one end of the water-passing kit, and the limiting block protrudes from the diameter reduction section of the filter element body.

[0039] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0040] This embodiment provides a comprehensive filter element with water-saving function, such as... Figures 1 to 7 As shown, the filter element 1 includes a filter element 2, a filter element body 3, and a water-passing kit 4;

[0041] The filter element 2 is installed on the filter body 3. The filter body 3 has a water passage cavity 31. One end of the water passage cavity 31 is an open end and the other end is a closed end. The water passage kit 4 is installed in a detachable manner on the open end of the water passage cavity 31. The water passage kit 4 has several water passage holes 41 that connect to the water passage cavity 31, so that the water flow from the water inlet hose 7 first flows through the water holes 41 and then enters the water passage cavity 31 of the filter body 3, which saves water and can buffer the water flow when the water pressure is high, ensuring that the water flow can pass smoothly through the filter element 1 for filtration, thereby improving the purification effect and the quality of the output water.

[0042] like Figure 8 and Figure 9 As shown, the shower handle 6 is provided with a water inlet 61 and a water passage 62 that connects to the water inlet 61. The filter element 1 is inserted into the water passage 62 from the water inlet 61. The water passage kit 4 of the filter element 1 is snapped into the water inlet 61. The filter element body 3 is provided with several flow holes 32 that connect the water passage cavity 31 and the water passage 62. The connector 71 of the water inlet hose 7 abuts against the water passage kit 4 and is detachably sealed to the water inlet 61. The water inlet hose 7 takes in water through the water inlet 61 and provides filtered water to the shower handle 6 through the filter element 1 and the water passage 62.

[0043] In this embodiment, the filter element 1 can be directly inserted into the water passage 62 from the water inlet 61 of the shower handle 6. At this time, the water passage kit 4 is snapped into the water inlet 61. The operation is simple. The connector 71 of the water inlet hose 7 abuts against the water passage kit 4 and is detachably sealed to the water inlet 61, so that the shower handle 6 can adopt an integrated design. This not only effectively reduces the processing cost, but also avoids the problem of water leakage when the shower handle 6 is used, and improves the user experience.

[0044] like Figure 5 and Figure 6 As shown, the filter body 3 is cylindrical. The filter body 3 has a diameter reduction section 33 at the open end of the water passage cavity 31. The size of the water passage kit 4 matches the size of the diameter reduction section 33 of the filter body 3. The water passage kit 4 is fitted onto the diameter reduction section 33 of the filter body 3 and fixed by means of a limiting block 34 and a limiting groove 44.

[0045] In this embodiment, the filter element body 3 has a diameter reduction section 33 at the open end of the water passage cavity 31, providing installation positioning for the water passage kit 4. Simply align the water passage kit 4 with the diameter reduction section 33 and insert it; the operation is simple. Furthermore, the use of the limiting block 34 in conjunction with the limiting groove 44 facilitates later disassembly for maintenance of the filter element 1. Of course, in other embodiments, the filter element body 3 can be configured in other shapes according to actual needs, such as... Figure 10 As shown, the filter body 3 is cuboid in shape, and it also has a cylindrical diameter reduction section 33 for mounting the water-passing kit 4.

[0046] like Figure 1 , Figure 2 and Figure 7 As shown, the water-passing kit 4 is cylindrical, and the diameter of the water-passing kit 4 is larger than the diameter of the diameter reduction section 33 of the filter element body 3. One end of the water-passing kit 4 forms an opening, and the limiting block 34 protrudes from the diameter reduction section 33 of the filter element body 3. The limiting groove 44 is set at the opening at one end of the water-passing kit 4 and matches the position of the limiting block 34.

[0047] In this embodiment, the water-passing kit 4 is also cylindrical. The diameter of the water-passing kit 4 is larger than the diameter of the diameter reduction section 33 of the filter element body 3. That is, the inner diameter of the opening at one end of the water-passing kit 4 matches the outer diameter of the diameter reduction section 33 of the filter element body 3. Initial positioning is achieved simply by aligning the opening of the water-passing kit 4 with the diameter reduction section 33, allowing the limiting block 34 to slide into the limiting groove 44. This facilitates the quick installation of the water-passing kit 4 and the diameter reduction section 33. Of course, in other embodiments, the diameter reduction section 33 can also be placed on the water-passing kit 4, in which case the outer diameter of the diameter reduction section 33 of the water-passing kit 4 matches the inner diameter of the filter element body 3. Simultaneously, the positions of the limiting block 34 and the limiting groove 44 can also be adjusted.

[0048] like Figures 1 to 4 As shown, in this embodiment, the limiting groove 44 is L-shaped, and the limiting block 34 protrudes from the diameter reduction section 33 of the filter element body 3. The limiting groove 44 is located at the opening of the water-passing kit 4. Specifically, during installation, the limiting groove 44 of the water-passing kit 4 is aligned with the limiting block 34 of the diameter reduction section 33 of the filter element body 3, and the limiting block 34 slides into the limiting groove 44. At this time, the water-passing kit 4 needs to be rotated relative to the axis of the filter element body 3 so that the limiting block 34 can be completely locked in the L-shaped limiting groove 44, making installation and removal convenient. In this embodiment, there are two limiting blocks 34 and two limiting grooves 44, but it is not limited to this. In other embodiments, the number and position of the limiting blocks 34 and the limiting grooves 44 can be adjusted, or other methods can be used to connect the water-passing kit 4 and the filter element body 3.

[0049] like Figures 1 to 5 , Figure 7 and Figure 9 As shown, the water passage hole 41 is located at the other end of the water passage kit 4, and the other end of the water passage kit 4 is radially protruding to form a flange 42, which abuts against the water inlet 61 of the shower handle 6.

[0050] In this embodiment, the water passage hole 41 is located at the other end of the water passage kit 4. When the water passage kit 4 is fitted onto the filter element body 3, the water from the inlet hose 7 first flows through the water passage hole 41 and then enters the water passage cavity 31 of the filter element body 3, thus saving water. The other end of the water passage kit 4 has a radially protruding flange 42. When the filter element 1 is inserted into the water passage 62 from the inlet port 61, the flange 42 of the water passage kit 4 can be engaged at the inlet port 61. Figure 8 and Figure 9 As shown, at this time, the filter element 1 can be installed on the shower handle 6 by sealing the connector 71 of the water inlet hose 7 to the water inlet interface 61 of the shower handle 6. The structure is simple and the operation is convenient.

[0051] like Figures 1 to 7 As shown, this embodiment also includes a sealing ring 5, a first annular groove 43 is provided at the other end of the water-passing kit 4, and a second annular groove 35 is provided in the diameter-reduced section 33 of the filter element body 3, as shown. Figure 5 As shown, the sealing rings 5 ​​are respectively fitted in the first annular groove 43 and the second annular groove 35, which can ensure the sealing of the water passage 62 of the shower handle 6 and improve the filtration and water output effect.

[0052] like Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, the water passage 41 includes a first water passage 411 and a second water passage 412. The first water passage 411 is located on the axis of the filter body 3 and can quickly introduce water flow into the central area of ​​the water passage cavity 31 of the filter body 3. The second water passage 412 is evenly distributed around the first water passage 411, which buffers and saves water flow while making the water flow more evenly into the water passage cavity 31 of the filter body 3, thereby improving the filtration effect.

[0053] like Figure 7 As shown, the size of the first water passage 411 is larger than the size of the second water passage 412, which can balance the water flow distribution and adapt to different water pressure environments. For example, under high water pressure, the larger size of the first water passage 411 can withstand greater water flow pressure, ensuring the normal operation of the filter element 1. Under low water pressure, the larger size of the first water passage 411 can reduce the resistance to water flow, allowing the filter element 1 to still maintain a certain water output even under lower water pressure. Of course, in other embodiments, the size of the water passage 41 can also be set according to actual needs.

[0054] like Figure 2 , Figure 4 and Figure 5 As shown, the flow holes 32 are elongated and evenly spaced axially on the filter body 3, which can maintain a uniform and stable water flow and improve the filtration effect. In other embodiments, the size, number, and location of the flow holes 32 can be adjusted according to actual needs.

[0055] like Figure 1 , Figure 3 and Figure 5 As shown, the filter element 2 is a filter screen 21, which is fitted onto the filter element body 3. This allows water flowing from the water passage cavity 31 of the filter element body 3 through the flow holes 32 to be filtered and purified by the filter screen 21 before flowing into the water passage channel 62 of the shower handle 6, ensuring the filtration effect. Alternatively, in other embodiments, scale-inhibiting filter media can be installed in the water passage cavity 31 of the filter element body 3 for further filtration. That is, either the filter screen 21 or the scale-inhibiting filter media can be installed, or one of the two can be selected.

[0056] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0057] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
