Description

Technical Field

[0001] This invention relates to the field of faucet water purifier technology, specifically to a faucet water purifier with a three-stage water outlet structure. Background Technology

[0002] Water purifiers can purify raw water (e.g., tap water) to meet user needs. Some faucet water purifiers have a three-speed system, allowing users to switch between purified water, shower, and aeration functions using a switching valve. The switching valve has an inner cavity with a baffle plate containing three water outlets. A rotating valve core switches the inlet between these three outlets. A sealing ring is required between the valve core and the baffle plate. However, this design is prone to wear during switching, resulting in poor sealing and a short lifespan. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a faucet water purifier with a three-stage water outlet structure that has good sealing performance and long service life.

[0004] To solve the above-mentioned technical problems, the present invention provides a faucet water purifier with a three-stage water outlet structure, including a main unit upper cover, a main unit lower cover, and a switching valve core. The main unit upper cover is connected to the upper end of the main unit lower cover. The switching valve core is located inside the main unit lower cover and the main unit upper cover. The switching valve core has a vertically penetrating inner cavity. A horizontally arranged partition is provided in the middle of the inner cavity. The partition has a vertically penetrating first water outlet, second water outlet, and third water outlet. A filter element assembly is connected to the main unit upper cover. The filter element assembly has an adapter interface. A water outlet channel is provided on the partition and connects to the adapter interface. The main unit lower cover has a shower outlet and an aerator. The first water outlet, second water outlet, and third water outlet are respectively connected to one of the water outlet channel, the shower outlet, and the aerator. A lower ceramic valve core and an upper ceramic valve core are provided in the inner cavity. Both the core and the upper ceramic valve core are located above the partition. The lower ceramic valve core has a first through hole, a second through hole, and a third through hole that are respectively connected to the first water outlet, the second water outlet, and the third water outlet. Several first sealing rings are provided between the lower ceramic valve core and the partition, and the several first sealing rings are respectively located on the outer edges of the first water outlet, the second water outlet, and the third water outlet. The upper ceramic valve core is located at the upper end of the lower ceramic valve core and has a fourth through hole. The switch valve core has a rotating shaft inside and the rotating shaft is connected to the upper ceramic valve core. The rotating shaft rotates synchronously with the upper ceramic valve core. The rotating shaft is connected to a handle. By rotating the handle, the rotating shaft and the upper ceramic valve core are rotated, so that the fourth through hole is connected to one of the first, second, and third through holes. The faucet water purifier also has an inlet, which is connected to the fourth through hole.

[0005] With the above structure, the faucet water purifier with a three-stage water output structure of the present invention has the following advantages: By rotating the handle, the rotating shaft and the upper ceramic valve core are driven to rotate, so that the fourth through hole is connected to one of the first through hole, the second through hole and the third through hole, thereby switching the corresponding water purification stage, shower stage and aeration stage of the faucet water purifier. During the switching process, the lower ceramic valve core will not rotate relative to the partition plate, the rotation resistance is smaller, thus avoiding wear of the first sealing ring, improving the sealing performance and extending the service life. Moreover, the stage switching is achieved only through the lower ceramic valve core, the upper ceramic valve core and the rotating shaft, making the structure simpler. Both the lower ceramic valve core and the upper ceramic valve core are made of ceramic material, which has good sealing performance, wear resistance, long service life and low frictional resistance.

[0006] As an improvement, the second, first, and third water outlets are sequentially distributed circumferentially on the partition plate. The angle between the line connecting the axis of the second water outlet to the rotation center of the shaft and the line connecting the axis of the first water outlet to the rotation center of the shaft is α, and the angle between the line connecting the axis of the third water outlet to the rotation center of the shaft and the line connecting the axis of the first water outlet to the rotation center of the shaft is α. The second, first, and third through holes are sequentially distributed circumferentially on the lower ceramic valve core, and the second, first, and third through holes are located directly above the second, first, and third water outlets, respectively. There are three fourth through holes, each corresponding to one of the first, second, and third through holes. One or three fourth through holes are distributed circumferentially on the upper ceramic valve core. The angle between the center of the middle fourth through hole and the rotation center of the shaft and the angle between the center of the fourth through holes on both sides and the rotation center of the shaft is β. When switching from connecting the second through hole and its corresponding fourth through hole to connecting the third through hole and its corresponding fourth through hole, the handle rotates by an angle γ, where α + γ / 2 = β. With this structure, by setting three fourth through holes corresponding to the first, second, and third through holes respectively, and α + γ / 2 = β, the rotation angle of the handle can be reduced each time the gear is switched, which not only simplifies the structure of the handle but also makes the operation more convenient.

[0007] As an improvement, the rotating shaft is located in the middle of the partition, and the upper end of the rotating shaft passes through the partition and is connected to the ceramic valve core. The partition has a notch that extends to the outer peripheral wall of the switch valve core and penetrates the outer peripheral wall of the switch valve core. A fixed bracket is connected radially to the rotating shaft. The fixed bracket passes through the notch and is connected to the handle. A clearance groove is provided circumferentially on the outer peripheral wall of the main unit cover. The handle passes through the clearance groove and protrudes outside the main unit cover. This structure has the advantages of simple structure and stable transmission.

[0008] As an improvement, an arc-shaped first extension is provided on the end of the fixed bracket that is exposed outside the switch valve core. The first extension is arranged along the outer peripheral wall of the switch valve core. Two abutment parts are provided on the outer peripheral wall of the switch valve core. The rotation angle γ is used to rotate the fixed bracket from one end of the first extension to abut one of the abutment parts to the other end of the first extension to abut the other abutment part. With this structure, the rotation range of the fixed bracket is limited by the two abutment parts and the first extension, that is, the rotation range of the handle is limited.

[0009] As an improvement, a first limiting groove is provided on the outer peripheral wall of the switch valve core. The angle between the central axis of the two abutting parts and the central axis of the first limiting groove is equal. A first spring is provided in the first limiting groove, and the first spring is connected to a first limiting member. Three second limiting grooves are provided on the inner peripheral wall of the first extension part along the circumferential arc, and the angle of the central angle corresponding to the arc is γ / 2. When the first limiting member is engaged in one of the second limiting grooves, one of the fourth through holes connects to the first through hole, the second through hole, or the third through hole. With this structure, the three second limiting grooves correspond to three different gears. During the gear shifting process, the first limiting member engaging in the second limiting groove indicates that the gear shift is complete, which increases the tactile feedback during the gear shifting process and makes the operation simpler.

[0010] As an improvement, a second sealing ring is provided between the shaft and the partition; this structure increases the sealing performance between the shaft and the partition.

[0011] As an improvement, the upper surface of the partition plate is provided with a first groove for installing the first sealing ring, and the lower surface of the lower ceramic valve core is provided with a second groove for installing the first sealing ring. The first sealing ring is embedded in the first groove and the second groove. This structure further enhances the sealing performance between the partition plate and the lower ceramic valve core.

[0012] As an improvement, a second extension is provided radially at the upper end of the rotating shaft. The second extension is connected to the upper ceramic valve core. The upper surface of the upper ceramic valve core is provided with several third limiting grooves. Each third limiting groove is provided with a second spring. Each second spring is provided with a spherical abutment at its upper end. The second extension is provided with several fifth through holes. A water sealing cover is also fixedly connected inside the switch valve core. The water sealing cover is located above the upper ceramic valve core. Each spherical abutment passes through one of the fifth through holes and abuts against the lower surface of the water sealing cover. With this structure, the compressed second spring applies a downward elastic force to the upper ceramic valve core, so that the upper ceramic valve core applies pressure to the lower ceramic valve core, making the lower ceramic valve core and the partition more tightly connected, and further compressing the first sealing ring, thereby further improving the sealing performance between the lower ceramic valve core and the partition.

[0028] The following is a detailed description of a faucet water purifier with a three-stage water outlet structure according to the present invention, with reference to the accompanying drawings.

[0029] like Figures 1 to 14 As shown, a faucet water purifier with a three-stage water outlet structure includes a main unit upper cover 1, a main unit lower cover 2, and a switch valve core 3. The main unit upper cover 1 is connected to the upper end of the main unit lower cover 2. The switch valve core 3 is located inside the main unit lower cover 2 and the main unit upper cover 1. The switch valve core 3 has a vertically penetrating inner cavity 50. A horizontally arranged partition 4 is provided in the middle of the inner cavity 50, and the partition 4 is integrally formed with the switch valve core 3. The partition 4 has a vertically penetrating first water outlet 5, a second water outlet 6, and a third water outlet 7. Figure 3 As shown, the second water outlet 6 and the third water outlet 7 are located on both sides of the first water outlet 5, and the first water outlet 5 is located between the second water outlet 6 and the third water outlet 7. The main unit cover 1 is connected to a filter element assembly 8, which is provided with an adapter 51. The partition 4 is provided with a water outlet 52, which connects to the adapter 51. The main unit cover 2 is provided with a shower outlet 9 and an aerator 10. The first water outlet 5, the second water outlet 6, and the third water outlet 7 are respectively connected to one of the water outlet 52, the shower outlet 9, and the aerator 10. In this embodiment, as shown... Figure 7 As shown, the first water outlet 5 is connected to the filter element assembly 8 through the water outlet 52 and the adapter 51, as follows: Figure 8 As shown, the second water outlet 6 connects to the shower head outlet 9, as... Figure 9As shown, the third water outlet 7 connects to the aerator 10. The showerhead outlet 9 has several through holes, and its specific structure is the same as that of existing showerheads. The specific structures of the filter element assembly 8 and the aerator 10 are also existing technologies and will not be described further here. Figure 11 As shown, in this embodiment, the aerator 10 is located in the middle of the lower cover 2 of the main unit, while the shower outlet 9 is located in the annular part of the lower cover 2 of the main unit other than the aerator 10.

[0030] like Figure 1 and Figure 2 As shown, the inner cavity 50 is provided with a lower ceramic valve core 11 and an upper ceramic valve core 12, both of which are located above the partition plate 4. The lower ceramic valve core 11 is fixedly connected to the switch valve core 3. In this embodiment, both the lower and upper ceramic valve cores 11 are made of ceramic material, providing good sealing, wear resistance, long service life, and low frictional resistance. The lower ceramic valve core 11 is provided with a first through hole 13, a second through hole 14, and a third through hole 15 respectively communicating with the first water outlet 5, the second water outlet 6, and the third water outlet 7. Figures 7 to 9 As shown, the first through hole 13 communicates with the first water outlet 5, the second through hole 14 communicates with the second water outlet 6, and the third through hole 15 communicates with the third water outlet 7. A plurality of first sealing rings 16 are provided between the lower ceramic valve core 11 and the partition plate 4, with the lower ends of the first sealing rings 16 respectively located at the outer edges of the first water outlet 5, the second water outlet 6, and the third water outlet 7, while the upper ends of the first sealing rings 16 are respectively located at the outer edges of the first through hole 13, the second through hole 14, and the third through hole 15; Figure 3 and Figure 4 As shown, the upper surface of the partition 4 is provided with a first groove 30, which is distributed along the outer edges of the first water outlet 5, the second water outlet 6 and the third water outlet 7. The lower surface of the lower ceramic valve core 11 is provided with a second groove 31, which is distributed along the outer edges of the first through hole 13, the second through hole 14 and the third through hole 15. Several first sealing rings 16 are integrally formed and embedded in the first groove 30 and the second groove 31. This improves the sealing between the lower ceramic valve core 11 and the partition 4, for example, preventing water in the first through hole 13 from flowing into the second water outlet 6 and the third water outlet 7.

[0031] like Figures 1 to 4As shown, the upper ceramic valve core 12 is located above the lower ceramic valve core 11, and the lower end face of the upper ceramic valve core 12 abuts against the upper end face of the lower ceramic valve core 11. The upper ceramic valve core 12 has a fourth through hole 17. A rotating shaft 18 is rotatably mounted inside the switch valve core 3 and is connected to the upper ceramic valve core 12. The rotating shaft 18 rotates synchronously with the upper ceramic valve core 12. A handle 19 is connected to the rotating shaft 18. Rotating the handle 19 drives the rotating shaft 18 and the upper ceramic valve core 12 to rotate, so that the fourth through hole 17 connects to one of the first through hole 13, the second through hole 14, and the third through hole 15. The fourth through hole 17 does not simultaneously connect to two or three of the first through hole 13, the second through hole 14, and the third through hole 15. The faucet water purifier also has an inlet 53, which connects to the fourth through hole 17. Specifically, as shown... Figure 7 As shown, the rotating shaft 18 is rotatably mounted in the middle of the partition 4, that is, the middle of the partition 4 has a shaft hole for mounting the rotating shaft 18. The upper end of the rotating shaft 18 passes through the partition 4 and is connected to the ceramic valve core 12. The partition 4 has a notch 20, which extends towards and through the outer peripheral wall of the switch valve core 3. A fixing bracket 21 is radially connected to the rotating shaft 18. The fixing bracket 21 passes through the notch 20 and is connected to the handle 19. The fixing bracket 21 is located inside the main unit cover 1. Figure 1 As shown, a clearance groove 22 is provided along the circumferential direction on the outer peripheral wall of the main unit cover 1. The handle 19 passes through the clearance groove 22 and protrudes outside the main unit cover 1. A second sealing ring 29 is provided between the rotating shaft 18 and the partition 4.

[0032] like Figure 5 As shown, the second water outlet 6, the first water outlet 5, and the third water outlet 7 are sequentially distributed circumferentially on the partition plate 4. The angle between the line connecting the axis of the second water outlet 6 and the rotation center of the rotating shaft 18 and the line connecting the axis of the first water outlet 5 and the rotation center of the rotating shaft 18 is α. The angle between the line connecting the axis of the third water outlet 7 and the rotation center of the rotating shaft 18 and the line connecting the axis of the first water outlet 5 and the rotation center of the rotating shaft 18 is α. The second through hole 14, the first through hole 13, and the third through hole 15 are sequentially distributed circumferentially on the lower ceramic valve core 11. The second through hole 14, the first through hole 13, and the third through hole 15 are located directly above the second water outlet 6, the first water outlet 5, and the third water outlet 7, respectively. There are three fourth through holes 17, and each fourth through hole 17 corresponds to one of the first through holes 13, the second through hole 14, and the third through hole 15. Figure 5 The fourth through hole 17 in the middle is used to communicate with the first through hole 13. Figure 5 The fourth through hole 17 at the top is used to connect to the second through hole 14. Figure 5The lower fourth through hole 17 is used to connect to the third through hole 15. The three fourth through holes 17 are distributed circumferentially on the upper ceramic valve core 12. The angle between the center of the middle fourth through hole 17 and the rotation center of the rotating shaft 18, and the angle between the center of the fourth through holes 17 on both sides and the rotation center of the rotating shaft 18, is β. When switching from connecting the second through hole 14 and its corresponding fourth through hole 17 to connecting the third through hole 15 and its corresponding fourth through hole 17, the angle through which the handle 19 rotates is γ, where α + γ / 2 = β. Figure 10 As shown, an arc-shaped first extension 23 is provided on the end of the fixed bracket 21 that protrudes outside the switch valve core 3. The first extension 23 is arranged along the outer peripheral wall of the switch valve core 3. Two abutment portions 24 are provided on the outer peripheral wall of the switch valve core 3. The rotation angle γ is used to rotate the fixed bracket 21 from one end of the first extension 23 abutting one of the abutment portions 24 to the other end of the first extension 23 abutting the other abutment portion 24. In other words, the maximum rotation angle of the handle 19 is limited by the abutment portion 24 and the first extension 23. When the handle 19 is rotated to the middle position of the two extreme positions, the angle between the two abutment portions 24 and the corresponding ends of the first extension portion 23 is γ / 2. Figure 10 and Figure 11 As shown, a first limiting groove 25 is provided on the outer peripheral wall of the switch valve core 3. The angle between the central axis of the two abutting parts 24 and the central axis of the first limiting groove 25 is equal. A first spring 26 is provided in the first limiting groove 25. The first spring 26 is connected to a first limiting member 27. Three second limiting grooves 28 are provided on the inner peripheral wall of the first extension part 23 along the circumferential arc, and the angle corresponding to the central angle of the arc is γ / 2. When the first limiting member 27 is engaged in one of the second limiting grooves 28, one of the fourth through holes 17 is connected to the first through hole 13 or the second through hole 14 or the third through hole 15. In this embodiment, α is 60°, β is 90°, and γ is 60°, that is, the angle between the line connecting the axis of the first through hole 13 and the rotation center of the rotating shaft 18 and the line connecting the axis of the second through hole 14 and the rotation center of the rotating shaft 18, and the angle between the first through hole 13 and the rotation center of the rotating shaft 18, and the angle between the axis of the first through hole 14 and the rotation center of the rotating shaft 18, and the angle between the axis of ... The angle between the line connecting the center of shaft 3 and the rotation center of shaft 18 and the line connecting the center of shaft 15 and the rotation center of shaft 18 is 60°. The angle between the line connecting the center of shaft 6 and the rotation center of shaft 18 and the line connecting the center of shaft 5 and the rotation center of shaft 18 is 60°. The angle between the line connecting the center of shaft 7 and the rotation center of shaft 18 and the line connecting the center of shaft 5 and the rotation center of shaft 18 is 60°. The angle between the center of the two adjacent fourth through holes 17 and the rotation center of shaft 18 is 90°. The central angle corresponding to the arc length of the first extension 23 is 150°. The angle between the two abutting parts 24 is 200°. When the handle 19 is rotated to the center of the two extreme positions, the first limiting member 27 is exactly engaged in the second limiting groove 28 located in the middle. Figure 5The fourth through hole 17, located in the middle, connects directly to the first through hole 13, and the angle between the two abutting portions 24 and the corresponding ends of the first extension portions 23 is 30°. If at this time... Figure 5 When the handle 19 is rotated 30° clockwise, the fourth through hole 17 located below connects to the third through hole 15, and the first limiting member 27 is engaged. Figure 11 The leftmost second limiting groove 28; if at this time in Figure 5 When the handle 19 is rotated counterclockwise by 30°, the fourth through hole 17 located at the top connects to the second through hole 14, and the first limiting member 27 is engaged. Figure 11 The rightmost second limiting groove 28. In this embodiment, the first limiting member 27 is a spherical structure, and the second limiting groove 28 is an arc surface.

[0033] like Figure 1 and Figure 2 As shown, the upper end of the rotating shaft 18 is provided with a fan-shaped second extension 32 along the radial direction. The second extension 32 is connected to the upper ceramic valve core 12. In this embodiment, the second extension 32 is engaged with the upper ceramic valve core 12. The upper surface of the upper ceramic valve core 12 is provided with a plurality of third limiting grooves 33. Each third limiting groove 33 is provided with a second spring 34. Each second spring 34 is provided with a spherical abutment 35 at its upper end. The second extension 32 is provided with a plurality of fifth through holes 36. A water sealing cover 37 is also fixedly connected inside the switch valve core 3. The water sealing cover 37 is located above the upper ceramic valve core 12. Each spherical abutment 35 passes through one of the fifth through holes 36 and abuts against the lower surface of the water sealing cover 37, and the second spring 34 is compressed. In this embodiment, there are two third limiting grooves 33, and correspondingly, there are also two fifth through holes 36. The upper end of the spherical abutment 35 is a spherical structure, while the lower end is a columnar structure and is inserted into the second spring 34. In addition, the second extension 32 is also provided with a sixth through hole 49 for avoiding the fourth through hole 17, so that the raw water can flow into the fourth through hole 17 from the sixth through hole 49. Figure 1 and Figure 2 As shown, the present invention also includes a threaded connector 45, a faucet locking ring 46, a mesh 47, and a water guide cover 48. The faucet locking ring 46 is threadedly connected to the switch valve core 3. The lower end of the threaded connector 45 is located inside the faucet locking ring 46, and the upper end is used to connect to the faucet. The mesh 47 is set on the water sealing cover 37. Raw water enters from the inlet 53 on the threaded connector 45, and after preliminary filtration by the mesh 47, it flows into the fourth through hole 17. The water guide cover 48 is set on the upper end of the aerator 10. Water in the third water outlet 7 flows into the aerator 10 through the water guide cover 48.

[0034] like Figures 12 to 14As shown, the filter element assembly 8 includes a filter housing cover 81 and a filter housing decorative cover 82. The filter housing decorative cover 82 is fitted over the filter housing cover 81, and the upper center of the filter housing decorative cover 82 is hollowed out. A lever 38 is engaged on the upper surface of the filter housing cover 81, and the lever 38 has a protrusion 39. A turntable 40 is rotatably mounted on the filter housing cover 81. Several fourth limiting grooves 41 are provided along the circumferential direction on the inner circumferential wall of the turntable 40. The protrusion 39 is engaged in one of the fourth limiting grooves 41. The upper end of the turntable 40 protrudes outside the filter housing decorative cover 82, and twelve scales are provided along the circumferential direction on the upper surface of the turntable 40. 42. Next to the scale 42, there are numerical markings 43 from 1 to 12, with each numerical marking 43 corresponding to one of the scales 42. An indicator mark 44 is provided on the upper end of the filter housing decorative cover 82. In this embodiment, there are two levers 38, each with a protrusion 39 facing opposite directions. There are 24 fourth limiting grooves 41, evenly distributed. The two protrusions 39 are respectively inserted into the two fourth limiting grooves 41. It should be noted that, to clearly show the structure between the levers 38, the turntable 40, and the filter housing cover 81, Figure 13 The document also describes the connection structure between lever 38 and the filter housing cover 81, as well as the connection structure between lever 38 and the turntable 40. Specifically, the two levers 38 on the filter housing cover 81 are the same as the two levers 38 on the turntable 40; this should not be interpreted as a total of four levers 38. The filter cartridges in the filter cartridge assembly 8 have a lifespan while filtering impurities and residual chlorine, and therefore need to be replaced periodically. Rotating the turntable 40 causes the indicator mark 44 to point to one of the scales 42. The number mark 43 next to this scale 42 indicates the month the filter cartridge should be replaced, ensuring timely replacement and safer drinking water. When switching gears, the handle 19 is rotated horizontally, causing the fixed bracket 21 to rotate. Since the fixed bracket 21 is connected to the rotating shaft 18, and the rotating shaft 18 is connected to the upper ceramic valve core 12 via the second extension 32, the upper ceramic valve core 12 rotates, thus switching gears.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiment. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
