Description

Technical Field

[0001] This utility model relates to a sealing ring and a water outlet device with a sealing ring, belonging to the technical field of water outlet devices. Background Technology

[0002] In related technologies, the water outlet device includes a handle and an outlet body connected to each other, with a water flow channel formed in the handle leading to the outlet body for water discharge. To obtain filtered clean water, existing technologies use an inlet filter element in the handle and an outlet filter element in the outlet body to achieve dual water filtration.

[0003] Application publication number CN111957450A discloses a carbon sheet filter top-spray whitening water purifier shower head, in which a filter element is installed inside the handle; simultaneously, a perforated mounting box is installed inside the spray head, and a sheet filter element is installed inside the perforated mounting box, achieving dual filtration to improve the filtration effect. To improve the sealing performance, a sealing ring is installed between the water outlet panel and the housing. This sealing ring is annular, and its installation direction is the same as the water flow direction, that is, the sealing ring is axially positioned between the water outlet panel and the housing. Under the impact of water pressure, the sealing performance of the sealing ring is affected, and the sealing effect is poor after long-term use, especially for water outlet devices with detachable water outlet panels. When the water outlet panel is disassembled and reassembled, gaps are easily generated due to insufficient assembly precision of the sealing ring, further affecting the sealing effect. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, one objective of the present invention is to provide a sealing ring that provides a better sealing effect and is particularly suitable for water outlet devices with detachable water outlet panels, ensuring that the sealing effect is not affected even if the water outlet panel is repeatedly disassembled and reassembled.

[0005] The second objective of this invention is to provide a water outlet device with a sealing ring.

[0006] To achieve the above objectives, the first embodiment of this utility model proposes a sealing ring, which is cylindrical and includes an mounting part and a sealing part that are axially connected to each other. The thickness of the sealing part in the radial direction is greater than the thickness of the mounting part in the radial direction. The inner sidewall of the sealing part is provided with an opening in the circumferential direction, and the opening is radially arranged so that the opening faces the center of the sealing ring.

[0007] According to an embodiment of the present invention, a sealing ring has an opening circumferentially provided on the inner sidewall of the sealing part. The opening is radially arranged so that it faces the center of the sealing ring. When the sealing ring is installed on the water outlet device, the opening undergoes elastic deformation under the pressure of water, so that the water pressure always acts on one side of the opening of the sealing ring, resulting in a better sealing effect. Moreover, it is particularly suitable for water outlet devices with detachable water outlet panels. Even if the water outlet panel is repeatedly disassembled and reassembled, the water pressure always acts on the opening of the sealing ring, so even if the installation accuracy of the sealing ring is not high, it will not affect its sealing effect.

[0008] In addition, the sealing ring proposed according to the above embodiments of this utility model may also have the following additional technical features: Optionally, the outer diameter of the sealing part is larger than the outer diameter of the mounting part; the inner diameter of the sealing part is equal to the inner diameter of the mounting part.

[0009] Optionally, the opening is configured as a V-shaped opening.

[0010] Optionally, the axial length of the mounting portion is greater than the axial length of the sealing portion.

[0011] Optionally, the axial length of the mounting portion is not less than 3 mm.

[0012] To achieve the above objectives, the second embodiment of this utility model proposes a water outlet device with a sealing ring, including the aforementioned sealing ring, as well as a housing, a water outlet panel, and a fixing component; The shell has a water passage cavity constructed by annular walls, the water passage cavity is connected to an external water source, and the end face of the annular walls has a receiving groove in the axial direction from the outside to the inside. The water outlet panel is composed of a closed end face and a water outlet end face in the radial direction from the outside to the inside. It is located on the water outlet opening end of the water passage cavity, and the closed end face of the water outlet panel is located at the insertion end of the receiving groove. The water outlet end face is connected to the water passage cavity. The fastener is detachably fixed to the housing, thereby confining the water outlet panel between the fastener and the housing; The mounting part of the sealing ring is inserted into the receiving groove, and the upper edge of the opening of its sealing part protrudes from the end face of the ring wall and abuts against the closed end face of the water outlet panel.

[0013] According to an embodiment of the present invention, a water outlet device with a sealing ring has an opening circumferentially provided on the inner sidewall of the sealing part of the sealing ring. The opening is radially arranged so that it faces the center of the sealing ring. When the water outlet device is in use, the opening of the sealing part undergoes elastic deformation under the pressure of water, so that the water pressure always acts on the opening side of the sealing ring. The sealing part of the sealing ring always firmly abuts against the water outlet panel, resulting in a good sealing effect. Moreover, it is particularly suitable for water outlet devices with detachable water outlet panels. Even if the water outlet panel is repeatedly disassembled and reassembled, the water pressure always acts on the opening of the sealing ring, so even if the installation accuracy of the sealing ring is not high, it will not affect its sealing effect.

[0014] In addition, the water outlet device with a sealing ring proposed in the above embodiments of this utility model may also have the following additional technical features: Optionally, the mounting portion of the sealing ring is interference-fitted with the side wall of the receiving groove, and the upper edge of the opening of the sealing ring is clearance-fitted with the side wall of the receiving groove.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. 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.

[0022] like Figures 1 to 7 As shown in the figure, a sealing ring according to an embodiment of the present invention is provided. The sealing ring 1 is cylindrical and includes a small-diameter mounting portion 11 and a large-diameter sealing portion 12 that are axially connected to each other. That is, the outer diameter of the sealing portion 12 is larger than the outer diameter of the mounting portion 11. An opening 121 is provided circumferentially on the inner sidewall of the sealing portion 12, and the opening 121 faces the center of the sealing ring 1, that is, the opening 121 is radially arranged. The opening 121 undergoes elastic deformation under water pressure to enhance its sealing performance. The opening 121 is preferably a V-shaped opening 121, which facilitates processing and provides better elastic deformation.

[0023] In some examples, the outer diameter of the sealing part 12 is larger than the outer diameter of the mounting part 11 to facilitate the setting of the opening 121, and at the same time, to prevent the opening 121 from being damaged during long-term use; the inner diameter of the sealing part 12 is equal to the inner diameter of the mounting part 11 to facilitate the forming of the sealing ring 1. The opening 121 is set as a V-shaped opening 121 to facilitate the processing and manufacturing of the opening 121.

[0024] In some examples, the axial length of the mounting part 11 is greater than the axial length of the sealing part 12, so that the sealing ring 1 is not easy to fall off when it is installed on the water outlet device, which is especially suitable for detachable shower heads.

[0025] In some examples, the axial length of the mounting portion 11 of the sealing ring 1 is not less than 3mm, which makes the friction of the sealing ring 1 greater when it is installed on the water outlet device, and the sealing ring 1 is not easy to fall off, which is especially suitable for detachable shower heads.

[0026] Because the inner wall of the sealing part 12 of the sealing ring 1 has an opening 121 circumferentially arranged, and the opening 121 is radially arranged so that the opening 121 faces the center of the sealing ring 1, when the sealing ring 1 is installed on the water outlet device, the opening 121 undergoes elastic deformation under the pressure of water pressure, so that the water pressure always acts on one side of the opening 121 of the sealing ring 1, resulting in a better sealing effect; moreover, it is particularly suitable for water outlet devices with detachable water outlet panels. Even if the water outlet panel is repeatedly disassembled and reassembled, since the water pressure always acts on the opening 121 of the sealing ring 1, even if the installation accuracy of the sealing ring 1 is not high, it will not affect its sealing effect.

[0027] like Figures 1 to 7 As shown, an embodiment of this utility model provides a water outlet device with a sealing ring, including the aforementioned sealing ring 1, a handle 2, a housing 3, a water outlet panel 4, and a fixing member 5. This utility model uses a handheld shower head as an example; of course, the water outlet device can be other structures such as an overhead shower.

[0028] A water flow channel is formed in the handle 2, which connects to the water inlet. In some examples, the water flow channel of the handle 2 is provided with an inlet filter element 21, which has a receiving cavity 211 for filling filter media. The filter media filled in the receiving cavity 211 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 21 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.

[0029] The housing 3 is connected to the handle 2. The connection between the housing 3 and the handle 2 can be detachable via a threaded connection, or it can be another detachable connection structure, such as a detachable connection structure where a protrusion engages with a slot, or it can be ultrasonically welded as a single unit. The housing 3 has a water-passing cavity 32 enclosed by an annular wall 31. The water-passing cavity 32 is connected to an external water source, meaning it communicates with the water flow channel in the handle 2. The annular wall 31 has an accommodating groove 33 formed axially from the outside to the inside on its end face. The annular wall 31 and the housing 3 can be integrally molded, but this results in higher mold costs.

[0030] In some examples, for ease of mold opening, the annular wall 31 and the housing 3 are separately configured. The annular wall 31 and the housing 3 are connected to form a water passage cavity 32. Specifically, the annular wall 31 and the housing 3 are separately configured, and then the annular wall 31 and the housing 3 are integrally connected by ultrasonic welding, or they can be integrally connected by threaded connection. Preferably, they are integrally connected by ultrasonic welding to enhance the sealing between the two.

[0031] The water outlet panel 4 is composed of a closed end face 41 and a water outlet end face 42 in the radial direction from the outside to the inside. The water outlet panel 4 is set on the water outlet opening end of the water passage cavity 32, and the closed end face 41 of the water outlet panel 4 is located at the insertion end of the receiving groove 33. The water outlet end face 42 is connected to the water passage cavity 32.

[0032] The fixing member 5 is detachably fixed to the housing 3, confining the water outlet panel 4 between the fixing member 5 and the housing 3. In this embodiment, the fixing member 5 is detachably connected to the annular wall 31; the water outlet panel 4 is confined between the fixing member 5 and the annular wall 31. The fixing member 5 and the annular wall 31 can be detachably connected by a threaded connection, or by other detachable connection structures, such as a detachable connection structure where a protrusion is inserted into a slot. In this embodiment, the fixing member 5 and the annular wall 31 are detachably connected by a circumferential protrusion 311 embedded in a circumferential slot 51. Specifically, a circumferential protrusion 311 is provided on the outer side wall of the annular wall 31, and a circumferential slot 51 is provided on the inner side wall of the fixing member 5. Rotating the fixing member 5 allows the circumferential protrusion 311 of the annular wall 31 to be embedded in the circumferential slot 51 of the fixing member 5. In this embodiment, the fixing member 5 is annular, and a retaining edge 52 is provided on the inner side wall of the water outlet end of the fixing member 5, which is used to abut against the water outlet panel 4.

[0033] The mounting portion 11 of the sealing ring 1 is inserted into the receiving groove 33, and the upper edge 1211 of the opening 121 of its sealing portion 12 protrudes from the end face of the annular wall 31 and abuts against the closed end face 41 of the water outlet panel 4. In some examples, the mounting portion 11 of the sealing ring 1 is interference-fitted with the side wall of the receiving groove 33 to prevent it from slipping off, and the upper edge 1211 of the opening 121 of the sealing ring 1 is clearance-fitted with the side wall of the receiving groove 33 to allow water to flow through the gap into the opening 121.

[0034] When the fixing part 5 is assembled with the ring wall 31, the water outlet panel 4 is limited and abuts against the baffle 52. The closed end face 41 of the water inlet side of the water outlet panel 4 abuts against the protruding end (upper edge 1211) of the sealing part 12 of the sealing ring 1. The water outlet side of the water outlet panel 4 abuts against the baffle 52. When the water flows through the water outlet end face 42 of the water outlet panel 4, due to the gap fit between the sealing part 12 of the sealing ring 1 and the side wall of the receiving groove 33, the water flows through the gap and enters the opening 121, which tightly presses the upper edge 1211 of the opening 121 of the sealing ring 1 against the closed end face 41 of the water outlet panel 4, preventing water from leaking out from the gap between the sealing ring 1 and the water outlet panel 4, thus achieving the sealing effect of the sealing ring 1.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, the receiving groove 33 has an axial length to accommodate the sealing ring 1, and the axial length is not less than 3mm. The axial length of the receiving groove 33 is less than the axial length of the sealing ring 1, so that when the sealing ring 1 is embedded in the receiving groove 33, the sealing part 12 of the sealing ring 1 protrudes from the end of the annular wall 31, that is, the sealing ring 1 protrudes from the receiving groove 33. As described above, since the mounting part 11 of the sealing ring 1 and the side wall of the receiving groove 33 form an interference fit, the sealing ring 1 is not easy to fall off. It is especially suitable for shower heads that frequently need to disassemble the water outlet panel 4 (such as for replacing the filter element of the water outlet device). The width of the receiving groove 33 is adapted to the outer diameter of the sealing part 12 to accommodate the sealing part 12 of the sealing ring 1. When the sealing ring 1 is embedded in the receiving groove 33, the upper edge 1211 of the opening 121 of the sealing ring 1 is in clearance fit with the side wall of the receiving groove 33. That is, the side of the opening 121 of the sealing part 12 opposite to the mounting part 11 is left with the side wall of the receiving groove 33, so that water flows into the opening 121 and causes the sealing part 12 to deform under water pressure, thereby enhancing its sealing performance.

[0036] In some examples, the water outlet device also includes a water outlet filter element 6; the inner wall of the annular wall 31 is provided with a limiting ring 312, the water outlet filter element 6 is installed in the water passage cavity 32 of the annular wall 31, the water inlet end of the water outlet filter element 6 abuts against the limiting ring 312 of the annular wall 31, and the water outlet end of the water outlet filter element 6 abuts against the water inlet side of the water outlet panel 4.

[0037] The water outlet filter element 6 is filled with water outlet filter media, which is activated carbon fiber. Since the water inlet end of the water outlet filter element 6 abuts against the limiting ring 312 of the ring wall 31, and the water outlet end of the water outlet filter element 6 abuts against the water inlet side of the water outlet panel 4, the water flows through the water inlet filter element 21 of the handle 2 and enters the water passage chamber 32, and then enters the water outlet filter element 6 through the water passage chamber 32 to achieve a better filtration effect. The water filtered by the water outlet filter element 6 flows out through the water outlet panel 4.

[0038] like Figure 5 , Figure 6 and Figure 7As shown, the water outlet filter element 6 includes an upper shell 61 and a lower shell 62 that are interlocked. The upper shell 61 and lower shell 62, when interlocked, form a filling cavity 63. The water outlet filter material, which is activated carbon fiber, is filled in the filling cavity 63. To facilitate the assembly and disassembly of the upper shell 61 and lower shell 62, an upper retaining ring 611 is formed axially around the water outlet end of the upper shell 61, forming an upper receiving space 612. A snap fastener 613 is formed circumferentially at the end of the outer wall of the upper retaining ring 611, and a guide block 614 is also formed axially on the outer wall of the upper retaining ring 611. A lower retaining ring 621 is formed axially around the water inlet end of the lower shell 62, forming a lower receiving space 622. A guide block 614 is formed circumferentially at the bottom of the inner side wall of the lower retaining ring 621. A concave limiting groove 623 is formed, and a guide opening 624 is axially formed on the side wall of the lower baffle ring 621. When the upper shell 61 and the lower shell 62 are assembled, the water outlet filter material is filled in the upper baffle ring 611, the guide block 614 is introduced into the guide opening 624, the upper baffle ring 611 is inserted into the lower baffle ring 621, and the buckle 612 is engaged in the limiting groove 623 to complete the assembly. At this time, the upper baffle ring 611 and its water inlet bottom and the water outlet bottom of the lower baffle ring 621 form a filling cavity 63.

[0039] Because the inner wall of the sealing part 12 of the sealing ring 1 has an opening 121 circumferentially, and the opening 121 is radially arranged so that the opening 121 faces the center of the sealing ring 1, when the water outlet device is in use, water flows through the gap between one side of the opening 121 and the side wall of the receiving groove 323 and enters the opening 121. The opening 121 undergoes elastic deformation under the pressure of water pressure, so that the water pressure always acts on one side of the opening 121 of the sealing ring 1, and the sealing part 12 of the sealing ring 1 always firmly abuts against the water outlet panel 4, resulting in a good sealing effect. Moreover, it is particularly suitable for water outlet devices with a detachable water outlet panel 4. Even if the water outlet panel 4 is repeatedly disassembled and reassembled, the water pressure always acts on the opening 121 of the sealing ring 1, so even if the installation accuracy of the sealing ring 1 is not high, it will not affect its sealing effect.
