Detailed implementation manners

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] The up-and-down toggle switch type faucet water purifier of the present invention, as Figure 2 and Figure 6 shown, includes a filter element 500. The filter element 500 belongs to the prior art and is used to filter impurities such as rust and sediment in tap water.

[0039] As Figure 2 and Figure 6 shown, the faucet water purifier of the present invention further includes a water path switching component 100, the water path switching component 100. As Figures 8 to 12As shown in the figure, the water path switching component 100 includes a tee 1. The tee 1 is formed with a water inlet 101, a raw water outlet 102, and a filtered water supply port 103. The filtered water supply port 103 is communicatively connected to the filter element 500. The water inlet 101 is formed at the upper part of the tee 1, and the raw water outlet 102 and the filtered water supply port 103 are formed at the lower part of the tee 1. The water inlet 101, the raw water outlet 102, and the filtered water supply port 103 are communicatively connected to each other. As Figures 8 to 12 shown in the figure, the water path switching component 100 further includes a raw water valve core 3 for closing the raw water outlet 102 and a purified water valve core 4 for closing the filtered water supply port 103. The raw water valve core 3 and the purified water valve core 4 are respectively slidably disposed within the tee 1. The raw water valve core 3 is connected to a second return spring 8 for pressing the raw water valve core 3 against the raw water outlet 102 to close it. That is to say, the elastic force of the second return spring 8 can keep the raw water valve core 3 in the position of closing the raw water outlet 102. The raw water valve core 3 and the purified water valve core 4 can respectively move up and down within the tee 1. The purified water valve core 4 is connected to a third return spring 9 for pressing the purified water valve core 4 against the filtered water supply port 103 to close it.

[0040] As Figures 8 to 11 shown in the figure, the water path switching component 100 further includes a slidably disposed switching member 2. As Figure 14 and Figure 15 shown in the figure, the switching member 2 is formed with a drive shaft 21. Specifically, as Figure 8 shown in the figure, the drive shaft 21 is slidably connected to the tee 1. As Figure 13 shown in the figure, specifically, the tee 1 is formed with a support hole 104, and the drive shaft 21 is adaptively connected to the support hole 104. Thus, the drive shaft 21 can move back and forth along the axis direction of the drive shaft 21. The back-and-forth movement direction of the drive shaft 21 is perpendicular to the sliding direction of the raw water valve core 3 and the purified water valve core 4. As Figure 8 and Figure 9 shown in the figure, the drive shaft 21 is used to be in contact connection with the raw water valve core 3 and the purified water valve core 4. Specifically speaking, as Figure 1 、 Figure 2 and Figure 8 shown in the figure, the drive shaft 21 is formed with an opening position boss 2103 for contacting and jacking up the raw water valve core 3 to open the raw water outlet 102 or contacting and jacking up the purified water valve core 4 to open the filtered water supply port 103.

[0041] As Figures 8 to 11 shown in the figure, the water path switching component 100 further includes a swingably disposed lever 5 for operating and switching between the raw water gear and the purified water gear. Specifically, the lever 5 is hinged to the tee 1. As Figure 8 and Figure 17As shown, the lever 5 is provided with a water purification switching pushing part 522 for pushing the switching part 2 inward to switch the state of the open position boss 2103 from lifting the raw water valve core 3 to lifting the purified water valve core 4 (the "inward" mentioned here refers to the inside of the three-way part 1).

[0042] As Figure 8 , Figure 10 and Figure 12 shown, the three-way part 1 is connected with a first return spring 6 for applying an outward thrust to the switching part 2 (the "outward" mentioned here refers to the outside of the three-way part 1). In other words, the switching part 2 can be reset by the elastic restoring force of the first return spring 6. Specifically, as Figure 7 and Figure 8 shown, the switching part 2 is formed with a push plate 22. The middle part of the back surface of the push plate 22 is integrally connected with one end of the driving shaft 21. The first return spring 6 is sleeved on the convex tube outside the three-way part 1. The above-mentioned support hole 104 is located at the center of the convex tube. The first return spring 6 is arranged between the outer wall of the three-way part 1 and the back surface of the push plate 22, and the driving shaft 21 passes through the first return spring 6.

[0043] The working principle of the present invention is briefly described as follows: In Figure 6 and Figure 8 , the water purifier of the present invention is in the raw water gear. At this time, the open position boss 2103 lifts the raw water valve core 3, and the second return spring 8 is further elastically compressed and deformed, so that the raw water valve core 3 leaves the raw water outlet 102, while the purified water valve core 4 is pressed on the filtered water supply port 103 by the elastic force of the third return spring 9 to close the filtered water supply port 103. As Figure 6 and Figure 8 shown by the arrows in, tap water enters the inner cavity of the three-way part 1 from the water inlet 101, and then the tap water flows in from between the raw water valve core 3 and the raw water outlet 102 and passes through the raw water outlet 102. Thus, the tap water is discharged in the raw water state; as Figure 7 shown, when the lever 5 is swung downward by hand, the water purification switching pushing part 522 swings around the swing center of the lever 5. Then, the water purification switching pushing part 522 can push the switching part 2 in the inner direction of the three-way part 1. Specifically, the water purification switching pushing part 522 can contact and push the push plate 22, so that the first return spring 6 is elastically compressed and deformed. Since the swing center of the lever 5 is located below the axis of the first return spring 6 (the first return spring 6 and the driving shaft 21 are coaxially arranged), in Figure 7 shown in the free state, since the elastic force of the first return spring 6 is supported by the swing center of the lever 5, and since in Figure 7 and Figure 9In the state shown, the force arm of the thrust of the first return spring 6 acting on the water purification switching pushing part 522 with respect to the swing center of the lever 5 is short, so that the moment of the elastic force of the first return spring 6 on the water purification switching pushing part 522 around the swing center of the lever 5 can be offset by the frictional force between the lever 5 and the tee 1. Thus, the lever 5 can be in force balance and achieve self-locking positioning in the Figure 7 state shown; since the drive shaft 21 moves towards the inside of the tee 1, the water purification valve core 4 is relatively slid up to the open position boss 2103, while the raw water valve core 3 is relatively slid to the outside of one side of the open position boss 2103. Thus, the filtered water supply port 103 is opened, and the elastic restoring force of the second return spring 8 pushes the raw water valve core 3 downward to reset and close the raw water outlet 102. Thus, the tap water flows through the filtered water supply port 103 as shown by the arrow in Figure 9 . The tap water then reaches the filter element 500, thereby achieving the switching to the water purification gear. In order to make it easier for the raw water valve core 3 and the water purification valve core 4 to relatively slide up or down the open position boss 2103, as shown in Figure 15 , the open position boss 2103 can be set to an isosceles trapezoid shape, so that guiding slopes are respectively formed on both sides of the open position boss 2103. As shown in Figure 8 and Figure 9 , when the lever 5 is manually toggled upward, causing the lever 5 to swing upward. During this process, the water purification switching pushing part 522 swings outward away from the push plate 22, and the push plate 22 also moves outward simultaneously under the push of the elastic restoring force of the first return spring 6. Thus, the raw water valve core 3 is relatively slid up to the open position boss 2103, while the water purification valve core 4 is relatively slid to the outside of the other side corresponding to the open position boss 2103, thereby switching back to the raw water gear. As can be known from the above description, the water path switching structure of the present invention realizes the mutual switching between the raw water gear and the water purification gear by easily toggling the lever 5. The operation process is simple and convenient. For example, the lever 5 can be set to correspond to the raw water gear at the obliquely upward positions shown in Figure 6 and Figure 8 , and the lever 5 corresponds to the water purification gear at the obliquely downward positions shown in Figure 7 and Figure 9 . The swing angle of the lever 5 from the raw water gear to the water purification gear can be set to about 90°. During daily use, when the faucet is closed, since the position state of the lever 5 can visually express the current gear state of the faucet water purifier, the user can easily judge the gear state of the faucet water purifier according to the position state of the lever 5, avoiding the need for the user to observe carefully, which is beneficial to convenient use and enables the elderly to have a good user experience.

[0044] Furthermore, as shown in Figure 16 , an avoidance hole 301 is formed in the middle of the raw water valve core 3 in the up and down direction. As shown in Figure 8 and Figure 16As shown, the upper edge of the avoidance hole 301 extends downward to form a first slider 31 for contact connection with the drive shaft 21. The first slider 31 can be set in an inverted triangular shape, and the lower tip of the first slider 31 can slide relative to the drive shaft 21, as Figure 15 As shown, on both sides of the open position boss 2103, a raw water closing position groove 2101 and a purified water closing position groove 2102 are respectively formed, as Figure 9 As shown, when in the purified water gear position, the first slider 31 is located in the raw water closing position groove 2101, and the raw water closing position groove 2101 serves to avoid the first slider 31. As Figure 16 As shown, a first sealing rubber block 32 for contact with the edge of the raw water outlet 102 is provided at the lower end of the raw water valve core 3. The first sealing rubber block 32 can be made of silicone rubber, as Figure 8 As shown, the first sealing rubber block 32 is buckled on the lower end part of the raw water valve core 3, as Figure 8 As shown, the drive shaft 21 is arranged through the avoidance hole 301. The above structural layout is reasonable, making the structure of the combination of the raw water valve core 3 and the drive shaft 21 compact. It can not only make the open position boss 2103 easily lift the raw water valve core 3, but also facilitate the layout so that the position of the first sealing rubber block 32 corresponds to the raw water outlet 102.

[0045] Furthermore, as Figure 16 As shown, a guide post 33 is formed at the upper end part of the raw water valve core 3, as Figure 9 and Figure 11 As shown, a water passing net cover 7 is correspondingly provided at the water inlet 101. An inlet hole 701 is formed on the water passing net cover 7. Thus, tap water can enter the inner cavity of the tee 1 through the inlet hole 701, as Figure 19 As shown, the water passing net cover 7 forms a cylinder cover 71. The guide post 33 is slidably connected in the corresponding cylinder cover 71 in a matching manner. Thus, through the guiding action of the cylinder cover 71, the raw water valve core 3 can stably move to open or close the raw water outlet 102. As Figure 8 As shown, the second return spring 8 can be sleeved on the guide post 33. The upper end of the second return spring 8 contacts the lower edge part of the cylinder cover 71, and the lower end of the second return spring 8 contacts the step on the raw water valve core 3, so that the elastic force of the second return spring 8 can be transmitted to the raw water valve core 3.

[0046] Furthermore, as Figure 19 As shown, a water passing hole 7101 is formed at the top of the cylinder cover 71, as Figure 8 and 9As shown, when the guide post 33 slides upward in the cylinder cover 71, it will squeeze the water in the cylinder cover 71. By providing a water passage hole 7101, the water in the cylinder cover 71 can be discharged in time, preventing the water in the cylinder cover 71 from hindering the upward movement of the guide post 33. When the guide post 33 moves downward, the water outside the cylinder cover 71 can also be replenished into the cylinder cover 71 through the water passage hole 7101 in time, preventing a negative pressure from forming in the cylinder cover 71 and affecting the downward movement of the raw water valve core 3.

[0047] As Figure 8 and Figure 12 shown, the structural principle of the purified water valve core 4 can be set to be the same as that of the raw water valve core 3. The purified water valve core 4 includes a second sealing rubber block 42, and the second sealing rubber block 42 is used to seal the filtered water supply port 103; As Figure 8 shown, in the raw water gear position, the second slider of the purified water valve core 4 is located within the purified water closed position groove 2102, while the first slider 31 of the raw water valve core 3 is contacted and lifted by the open position boss 2103. The purified water closed position groove 2102 is used to avoid the second slider of the purified water valve core 4; As Figure 9 shown, in the purified water gear position, the second slider of the purified water valve core 4 is contacted and lifted by the open position boss 2103, and the first slider 31 of the raw water valve core 3 is located within the raw water closed position groove 2101; Since the structural principle of the purified water valve core 4 can be set to be the same as that of the raw water valve core 3, the structure of the purified water valve core 4 will not be elaborated here.

[0048] Furthermore, as Figure 8 shown, the shift lever 5 includes a handle 51 and a driving block 52. As Figure 17 shown, a purified water switching pushing portion 522 is formed on the driving block 52. As Figure 18 shown, a plugging rod portion 511 is formed at one end of the handle 51, and the plugging rod portion 511 is adaptively inserted into the driving block 52. The handle 51 and the driving block 52 can be snap-connected or interference-connected. Since the handle 51 and the driving block 52 are a split combined structure, it is beneficial to reduce the manufacturing difficulty of the shift lever 5 and beneficial to reduce the manufacturing cost.

[0049] Furthermore, as Figure 13 shown, a support plate 11 is formed on the outside of the tee member 1. As Figure 17 shown, a hinge shaft portion 523 is formed on the driving block 52. Specifically, the hinge shaft portion 523 can be formed on the driving block 52. As Figure 11 shown, the shift lever 5 is hinged to the support plate 11 through the hinge shaft portion 523. Specifically, a hinge hole is formed on the support plate 11, and the hinge shaft portion 523 is adaptively inserted into the above-mentioned hinge hole. Thus, the shift lever 5 can swing around the axis of the hinge shaft portion 523, and the above structural arrangement is simple and reasonable. As Figure 14 shown, a first positioning groove 2201 and a second positioning groove 2202 can be formed on the outer side surface of the push plate 22. As Figure 17As shown, a raw water gear contact portion 521 is formed on the upper part of the drive block 52. The raw water gear contact portion 521 is located above the hinge shaft portion 523, while the purified water switching push portion 522 is located below the hinge shaft portion 523. Moreover, the distance from the raw water gear contact portion 521 to the axis of the hinge shaft portion 523 is less than the distance from the purified water switching push portion 522 to the axis of the hinge shaft portion 523, such that when the lever 5 swings to Figure 8 the position shown, the switching member 2 is in a relatively outer position, so that the opening position boss 2103 realizes the gear switching function. In Figure 8 the free state shown, the elastic force of the first return spring 6 still acts on the switching member 2. The elastic force of the first return spring 6 is supported by the support plate 11. Moreover, since the raw water gear contact portion 521 contacts the bottom of the first positioning groove 2201 and the purified water switching push portion 522 contacts the bottom of the second positioning groove 2202, the resultant moment of the first return spring 6 around the hinge shaft portion 523 on the drive block 52 is offset by the frictional force between the hinge shaft portion 523 and the support plate 11. Thus, the drive block 52 can be in force balance and remain stationary in Figure 8 the raw water gear state shown.

[0050] Furthermore, as Figures 1 to 7 shown, the faucet water purifier of the present invention further includes an upper housing 200 and a lower housing 300. The three-way member 1 is disposed in the cavity formed by the upper housing 200 and the lower housing 300. Specifically, as Figure 13 shown, an external thread joint portion 12 is formed on the upper part of the three-way member 1, and the external thread joint portion 12 protrudes upward beyond the upper housing 200; as Figure 3 shown, the upper housing 200 forms a cup housing portion 2006. In the top view direction, the cup housing portion 2006 is within the range of the upper housing 200. As Figure 1 , Figure 2 and Figure 6 shown, the filter element 500 is disposed in the cup housing portion 2006. As Figure 3 shown, the upper housing 200 forms a second sleeve portion 2001, and the cup housing portion 2006 forms a filtering inlet 2002. The second sleeve portion 2001 and the cup housing portion 2006 are communicated through the above-mentioned filtering inlet 2002. Specifically, the second sleeve portion 2001 is parallel to the cup housing portion 2006, the second sleeve portion 2001 abuts against the outside of the cup housing portion 2006, and the wall of the second sleeve portion 2001 is integrally connected with the wall of the cup housing portion 2006. As Figure 13 shown, the three-way member 1 forms a first sleeve portion 105, and the filtered water delivery port 103 is communicated with one end of the first sleeve portion 105; as Figure 2 and Figure 7As shown, the faucet water purifier of the present invention further includes a water delivery pipe 800. One end of the water delivery pipe 800 is inserted into the corresponding other end of the first sleeve portion 105, and the corresponding other end of the water delivery pipe 800 is inserted into the second sleeve portion 2001. The water delivery pipe 800 can be specifically set to be in the shape of a right-angle elbow, and corresponding sealing rings are provided at both ends of the water delivery pipe 800. As Figure 7 shown, when the faucet water purifier of the present invention is in the purified water gear, the tap water discharged from the filtered water delivery port 103 enters the water delivery pipe 800 through the first sleeve portion 105, and then the tap water enters the second sleeve portion 2001 and enters the cup housing portion 2006 through the filtered water inlet 2002, as Figure 1 and Figure 2 shown, the faucet water purifier of the present invention further includes a filter element cover 700, as Figure 7 shown, the lower end of the filter element cover 700 is screwed and installed with the upper end of the cup housing portion 2006, and corresponding sealing rings are provided between the inner wall of the filter element cover 700 and the outer end of the cup housing portion 2006. In addition, corresponding sealing rings are also provided between the lower end of the filter element 500 and the inner wall of the cup housing portion 2006. Therefore, when the tap water enters the space between the inner wall of the cup housing portion 2006 and the outside of the filter element 500, it will not leak, so that all the tap water needs to pass through the fine pore structure of the filter element 500 and then be discharged from the water outlet hole at the lower end of the filter element 500. By providing the water delivery pipe 800, it is convenient to connect the cup housing portion 2006 with the tee joint 1.

[0051] As Figure 3 shown, a purified water outlet 2005 is formed at the bottom of the cup housing portion 2006, as Figure 7 shown, the purified water outlet 2005 abuts and aligns with the water outlet hole at the lower end of the filter element 500. Therefore, the purified water filtered by the filter element 500 can be discharged from the purified water outlet 2005. More specifically, the purified water outlet 2005 protrudes downward beyond the lower housing 300. As Figure 4 shown, a raw water drain port 3004 is formed at the bottom of the lower housing 300, as Figure 6 shown, the raw water drain port 3004 is disposed directly below the raw water outlet 102. Therefore, when the faucet water purifier of the present invention is in the raw water gear, the tap water is discharged from the raw water outlet 102 to the raw water drain port 3004, and then the tap water is discharged downward from the raw water drain port 3004.

[0052] As Figure 1 、 Figure 2 and Figure 6As shown in the figure, the faucet water purifier of the present invention further includes a sealing gasket 6001, a faucet connector 6002 and a locking ring 6003. The sealing gasket 6001 is adapted to be disposed within the external thread joint portion 12 of the tee member 1, and the water inlet 101 is located within the external thread joint portion 12. The faucet connector 6002 is formed with an internal thread for screwing and installing with the outlet of the faucet. The locking ring 6003 is screwed with the external thread joint portion 12, and the inner edge portion of the locking ring 6003 is buckled on the flange portion of the faucet connector 6002. Thus, tightening the locking ring 6003 can press down the faucet connector 6002, so that the edge portion of the faucet connector 6002 is pressed against the sealing gasket 6001, thereby preventing tap water from leaking. The tap water discharged from the faucet passes through the faucet connector 6002 and reaches the water inlet 101 through the central hole of the sealing gasket 6001.

[0053] Further, as Figure 1 and Figure 2 shown, the edge portion of the upper housing 200 is buckled with the edge portion of the lower housing 300. Specifically, for example, as Figure 3 shown, the edge portion of the upper housing 200 is formed with buckle ears 2004, and the buckle ears 2004 are dispersedly arranged around the periphery of the upper housing 200. As Figure 4 shown, the edge portion of the lower housing 300 is formed with buckle hooks 3002, and the buckle hooks 3002 are buckled with the corresponding buckle ears 2004, so that the assembly of the upper housing 200 and the lower housing 300 is quick and convenient.

[0054] Further, as Figure 1 and Figure 2 shown, the faucet water purifier of the present invention further includes an outer housing 400 for covering the gap between the upper housing 200 and the lower housing 300. The upper part of the outer housing 400 is adaptively sleeved outside the upper housing 200, and the lower part of the outer housing 400 is adaptively sleeved outside the lower housing 300. Thus, it is possible to prevent dirt from accumulating in the gap between the upper housing 200 and the lower housing 300, which is convenient for cleaning and also helps to give the faucet water purifier of the present invention an overall aesthetic appearance.

[0055] Further, as Figure 3 shown, an upper insertion hole 2003 is formed inside the upper housing 200. As Figure 4 shown, a lower insertion hole 3001 is formed inside the lower housing 300. As Figure 5 shown, positioning posts 4001 extending in the up and down direction are formed on the inner side of the outer housing 400. As Figure 1 、 Figure 2 and Figure 20As shown, the upper insertion hole 2003 is adaptively connected to the upper part of the positioning post 4001, and the lower insertion hole 3001 is adaptively connected to the lower part of the positioning post 4001. Thus, through the positioning function of the positioning post 4001, the outer casing 400, the upper casing 200, and the lower casing 300 can be accurately positioned relative to each other.

[0056] Furthermore, as Figure 3 shown, the upper insertion hole 2003 is formed with a first notch 2007 that penetrates the upper casing 200 outward. The upper insertion hole 2003 is arranged near the edge of the upper casing 200. As Figure 4 shown, the lower insertion hole 3001 is formed with a second notch 3005 that penetrates the lower casing 300 outward. As Figure 5 shown, a connecting piece 4003 integrated with the positioning post 4001 is formed on the inner wall of the outer casing 400. As Figure 1 and Figure 20 shown, the upper part of the connecting piece 4003 is arranged in the first notch 2007, and the lower part of the connecting piece 4003 is arranged in the second notch 3005. That is to say, both the first notch 2007 and the second notch 3005 are used to avoid the connecting piece 4003, which is beneficial to setting a relatively long connection length of the connecting piece 4003 and the positioning post 4001 along the axial direction of the positioning post 4001, and is beneficial to increasing the connection strength between the positioning post 4001 and the main body of the outer casing 400.

[0057] Furthermore, as Figure 5 shown, the outer casing 400 is formed with a limiting hole 4002 for limiting the shift lever 5. As Figure 1 and Figure 6 shown, the shift lever 5 is arranged through the limiting hole 4002. That is to say, as Figure 6 shown, when the faucet water purifier is in the raw water gear, the shift lever 5 abuts against the upper edge of the limiting hole 4002. As Figure 7 shown, when the faucet water purifier is in the purified water gear, the shift lever 5 abuts against the lower edge of the limiting hole 4002, which is beneficial to making the gears of the raw water gear and the purified water gear clear, and is also beneficial to the drive shaft 21 being able to accurately stop at the required gear position.

[0058] As Figure 2 shown, during the assembly process of the faucet water purifier of the present invention, first, the outer casing 400 is sleeved outside the lower casing 300 from bottom to top, and then the water path switching assembly 100 is installed in the lower casing 300. Specifically, the shift lever 5 first obliquely passes through the limiting hole 4002 of the outer casing 400. As Figure 4 shown, a support post 3003 is formed inside the lower casing 300, and a threaded hole is formed at the upper end of the support post 3003. After the three-way fitting 1 is positioned, the three-way fitting 1 is fixed to the support post 3003 with screws. As Figure 17As shown, the right side of the driving block 52 is hemispherical, and the limiting hole 4002 can be set as a round hole. Thus, the hemispherical structure of the driving block 52 partially sinks into the limiting hole 4002, preventing debris from entering the outer casing 400 through the limiting hole 4002. Insert one end of the water delivery pipe 800 into the first sleeve portion 105 of the tee 1, and then fasten the upper outer casing 200 to the lower outer casing 300. Thus, the positioning post 4001 is inserted into the upper insertion hole 2003 and the lower insertion hole 3001. The upper insertion hole 2003 and the lower insertion hole 3001 are in interference fit with the positioning post 4001. During this process, the corresponding other end of the water delivery pipe 800 is inserted into the second sleeve portion 2001 of the upper outer casing 200. Then, insert the filter element 500 downward into the cup shell portion 2006 of the upper outer casing 200. Cover the filter element cover 700 outside the upper part of the filter element 500 and screw it and fasten it to the cup shell portion 2006. Then, place the sealing gasket 6001 on the water inlet 101, place the faucet connector 6002 on the sealing gasket 6001, and then screw the locking ring 6003 to the external thread joint portion 12.

[0059] In summary, the faucet water purifier of the present invention can switch between the raw water gear and the purified water gear by operating the lever 5 to move it up and down. The switching operation is simple, convenient and intuitive.
