Description

Technical Field

[0001] This utility model relates to a handheld shower head with a water outlet filter element, belonging to the technical field of water outlet devices. Background Technology

[0002] In related technologies, handheld showerheads include a handle and a water outlet body connected to each other, with a water flow channel formed in the handle leading to the water outlet body for water dispensing. To obtain filtered water, existing technologies use a filter cartridge installed in the handle to achieve water filtration; however, the filtration effect is limited by the limited space in the handle.

[0003] To further improve the filtration effect, application publication number CN11195745A discloses a carbon disc filter top spray whitening water purifier shower head, in which an inlet filter is installed inside the handle; at the same time, an outlet filter is installed in the water outlet body, achieving dual filtration to improve the filtration effect. However, the inlet end of the outlet filter directly abuts against the spray head housing, resulting in insufficient use of the filter; at the same time, the outlet end of the outlet filter directly abuts against the water outlet panel, making it prone to clogging and affecting water flow; moreover, the filter is directly installed in the spray head housing, and the seal between the side wall of the filter and the spray head housing is poor, allowing water to easily spray out directly through the water outlet panel without being filtered by the filter, affecting the filtration effect. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide a handheld shower head with a water outlet filter element, which provides good filtration, smooth water flow without clogging, simple assembly, and good sealing.

[0005] To achieve the above objectives, this utility model provides a handheld shower head with a water outlet filter element, comprising: A handle, wherein a water flow channel is formed in the handle; The water outlet body includes a water outlet shell, a connecting seat, a water outlet panel, and a fixing member; the water outlet shell is connected to the handle, and the water outlet shell forms a water passage cavity communicating with the water flow channel; the connecting seat is connected to the water outlet shell, and the connecting seat has an installation cavity communicating with the water passage cavity of the water outlet shell, and a limiting ring is provided on the inner wall of the side of the installation cavity connected to the water passage cavity; the fixing member is detachably connected to the connecting seat; the water outlet panel is confined between the fixing member and the connecting seat; The water outlet filter element is installed in the mounting cavity of the connecting seat. The water inlet end of the water outlet filter element abuts against the limiting ring of the connecting seat, and the water outlet end of the water outlet filter element abuts against the water inlet side of the water outlet panel.

Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0020] like Figures 1 to 6As shown in the figure, a handheld shower head with a water outlet filter element according to an embodiment of the present invention includes a handle 1, a water outlet body 2, and a water outlet filter element 3.

[0021] like Figure 4 As shown, a water flow channel is formed in the handle 1, which is connected to the water inlet. In some examples, the water flow channel of the handle 1 is provided with an inlet filter element 4, which has a receiving cavity 41 for filling filter media. The filter media filled in the receiving cavity 41 can be at least one of the following: calcium sulfite, blue antibacterial balls, maifanite balls, wood fish stone balls, KDF, activated carbon, scale inhibitor granules, VC balls, tourmaline balls, negative ion balls, PP cotton sheets, activated carbon balls, defluorination balls, and high magnetic energy balls. The outlet end of the inlet filter element 4 is designed to have a detachable end, and the filter media can be used as a soil additive for cultivating plants after use, making the filter media more environmentally friendly through secondary utilization.

[0022] like Figure 1 and Figure 2 As shown, the water outlet body 2 includes a water outlet shell 21, a connecting seat 22, a water outlet panel 23, and a fixing member 24. The water outlet shell 21 is connected to the handle 1. The connection between the water outlet shell 21 and the handle 1 can be threaded and detachable, or it can be other detachable connection structures, such as a detachable connection structure where a protrusion is inserted into a slot, or it can be ultrasonically welded. The water outlet shell 21 forms a water passage cavity 211 that communicates with the water flow channel. The water passage cavity 211 can be surrounded by a baffle 212 provided in the water outlet shell 21. The baffle 212 has a connection hole that communicates with the water flow channel. After the water flows through the water inlet filter element 4 provided in the water flow channel of the handle 1, it enters the water passage cavity 211 through the connection hole.

[0023] The connecting seat 22 is connected to the water outlet housing 21. The connecting seat 22 and the water outlet housing 21 can be integrally connected by ultrasonic welding or by threaded connection. Preferably, they are integrally connected by ultrasonic welding to enhance the sealing between them. The connecting seat 22 is provided with a mounting cavity 221 that communicates with the water passage cavity 211 of the water outlet housing 21. A limiting ring 2211 is provided on the inner wall of the side of the mounting cavity 221 that connects to the water passage cavity 211. The water inlet end of the connecting seat 22 is connected to the enclosure 212 in the water outlet housing 21 by ultrasonic welding.

[0024] The fixing member 24 is detachably connected to the connecting seat 22. The connection between the fixing member 24 and the connecting seat 22 can be threaded or other detachable connection structures, such as a detachable connection structure where a protrusion engages with a slot. In some examples, the fixing member 24 and the connecting seat 22 are detachably connected by a circumferential rib 222 embedded in a circumferential slot 241. Specifically, a circumferential rib 222 is provided on the outer side wall of the connecting seat 22, and a circumferential slot 241 is provided on the inner side wall of the fixing member 24. Rotating the fixing member 24 allows the circumferential rib 222 of the connecting seat 22 to be embedded in the circumferential slot 241 of the fixing member 24. In this embodiment, the fixing member 24 is annular, and a fixing ring 242 is provided on the inner side wall of the water outlet end of the fixing member 24, which abuts against the water outlet panel 23.

[0025] The water outlet panel 23 is positioned between the fixing member 24 and the connecting seat 22. In some examples, a sealing ring 5 is provided between the connecting seat 22 and the water outlet panel 23. Specifically, the water outlet side end face of the connecting seat 22 is provided with a receiving groove 223 along the circumferential direction. The receiving groove 223 has an axial depth to accommodate the sealing ring 5, and the axial depth of the receiving groove 223 is less than the height of the sealing ring 5, so that the sealing ring 5 protrudes from the receiving groove 223. At this time, the water inlet end of the water outlet panel 23 abuts against the sealing ring 5, and the water outlet end of the water outlet panel 23 abuts against the fixing ring 242 of the fixing member 24, resulting in good sealing performance.

[0026] The water outlet filter element 3 is installed in the mounting cavity 221 of the connecting seat 22. The water inlet end of the water outlet filter element 3 abuts against the limiting ring 2211 of the connecting seat 22, and the water outlet end of the water outlet filter element 3 abuts against the water inlet side of the water outlet panel 23. A buffer cavity 6 is formed between the water outlet end of the water outlet filter element 3 and the water outlet panel 23. The water outlet filter element 3 is filled with water outlet filter media, which is activated carbon fiber.

[0027] like Figure 1 , Figure 2 and Figure 6As shown, in some examples, the water outlet filter element 3 includes an upper shell 31 and a lower shell 32 that are interlocked. The upper shell 31 and lower shell 32, after being interlocked, form a filling cavity 33. The water outlet filter material, which is activated carbon fiber, is filled in the filling cavity 33. To facilitate the assembly and disassembly of the upper shell 31 and lower shell 32, an upper retaining ring 311 is formed axially around the water outlet end of the upper shell 31. The upper retaining ring 311 encloses an upper receiving space 312. A snap fastener 313 is formed circumferentially at the end of the outer side wall of the upper retaining ring 311. A guide block 314 is also formed axially on the outer side wall of the upper retaining ring 311. A lower retaining ring 321 is formed axially around the water inlet end of the lower shell 32. The lower retaining ring 321 encloses a lower receiving space 322. A guide block 314 is formed circumferentially at the bottom of the inner side wall of the lower retaining ring 321. A concave limiting groove 323 is formed, and a guide opening 324 is also formed axially on the side wall of the lower baffle ring 321. When the upper shell 31 and the lower shell 32 are assembled, the water outlet filter material is filled in the upper baffle ring 311, the guide block 314 is introduced into the guide opening 324, the upper baffle ring 311 is inserted into the lower baffle ring 321, and the buckle 313 is snapped into the limiting groove 323 to complete the assembly. At this time, the upper baffle ring 311 and its water inlet bottom and the water outlet bottom of the lower baffle ring 321 form a filling cavity 33.

[0028] If the handle 1 of the handheld shower head is equipped with an inlet filter cartridge 4, and the filter media of the inlet filter cartridge 4 is one or more combinations of calcium sulfite, blue antibacterial balls, maifan stone balls, mochi stone balls, KDF, activated carbon, scale inhibitor granules, VC balls, tourmaline balls, negative ion balls, PP cotton sheets, activated carbon balls, defluoridation balls, and high magnetic energy balls, then the filter media of the outlet filter cartridge 3 of the outlet body 2 is preferably an ACF filter cartridge (activated carbon limiting filter cartridge). If the handle 1 is not equipped with an inlet filter cartridge 4, the filter media of the outlet filter cartridge 3 of the outlet body 2 can also be one or more combinations of calcium sulfite, blue antibacterial balls, maifan stone balls, mochi stone balls, KDF, activated carbon, scale inhibitor granules, VC balls, tourmaline balls, negative ion balls, PP cotton sheets, activated carbon balls, defluoridation balls, and high magnetic energy balls. Meanwhile, the water outlet filter element 3 includes an upper housing 31 and a lower housing 32 that are interlocked with each other, making the water outlet filter element 3 detachable. When the water outlet filter element 3 is used, its filter media can be used as an additive for the soil, which is more environmentally friendly.

[0029] like Figure 3 and Figure 4As shown, the inlet end of the water outlet filter element 3 abuts against the limiting ring 2211 of the connecting seat 22, and the outlet end of the water outlet filter element 3 abuts against the inlet side of the water outlet panel 23. A buffer chamber 6 is formed between the outlet end of the water outlet filter element 3 and the water outlet panel 23. This allows water to flow through the inlet filter element 4 of the handle and into the water passage chamber 211 of the water outlet housing 21. From the water passage chamber 211, water enters the water outlet filter element 3, ensuring full utilization of the water outlet filter element 3 for better filtration. The water filtered by the water outlet filter element 3 enters the buffer chamber 6 formed between the outlet end of the water outlet filter element 3 and the water outlet panel 23, ensuring smooth water flow without clogging. Then, the water flows out from the buffer chamber 6 through the water outlet panel 23. Therefore, the filtration effect is good, the water flow is smooth and not prone to clogging, and the assembly is simple.

[0030] like Figure 4 and Figure 5 As shown, in some examples, the sealing ring 5 includes a small-diameter mounting portion 51 and a large-diameter sealing portion 52 that are axially connected to each other. That is, the outer diameter of the sealing portion 52 is larger than the outer diameter of the mounting portion 51. A sealing opening 521 is provided circumferentially on the inner wall of the sealing portion 52. The opening of the sealing opening 521 faces the center of the sealing ring 5, that is, the sealing opening 521 is radially arranged. The sealing opening 521 undergoes elastic deformation under water pressure to enhance its sealing performance. The sealing opening 521 is preferably a V-shaped sealing opening 521, which facilitates processing and provides better elastic deformation. The axial length of the sealing ring 5 is greater than the axial depth of the receiving groove 223 of the connecting seat 22. When the sealing ring 5 is embedded in the receiving groove 223, the sealing part 52 of the sealing ring 5 protrudes from the end of the connecting seat 22. The width of the opening of the receiving groove 223 is adapted to the outer diameter of the sealing part 52 to accommodate the sealing part 52 of the sealing ring 5. Due to the large extrusion friction between the receiving groove 223 and the sealing ring 5, the sealing ring 5 is not easy to fall off, which is especially suitable for detachable shower heads. When the sealing ring 5 is embedded in the receiving groove 223, the sealing opening 521 of the sealing part 52 on the side opposite to the mounting part 51 leaves a gap with the side wall of the receiving groove 223 of the connecting seat 22, so that water flows into the sealing opening 521 and causes the sealing part 52 to deform under water pressure, thereby enhancing its sealing performance.

[0031] like Figure 4 and Figure 5 As shown, when the fixing member 24 is assembled with the connecting seat 22, the water outlet panel 23 is limited and abuts against the fixing ring 242. The water outlet panel 23 is provided with water jet holes. Specifically, the water inlet side of the water outlet panel 23 abuts against the end of the sealing part 52 of the sealing ring 5, and the water outlet side of the water outlet panel 23 abuts against the fixing ring 242. When water flows through the water outlet panel 23, the water flows into the sealing opening 521, causing the sealing part 52 to deform under the action of water pressure, driving the sealing part 52 to press tightly against the water outlet panel 23 to enhance its sealing performance.
