As an example, the water purification tank cartridge 80 coupled to the water faucet direct-coupled water purifier 90 according to one embodiment of the present invention shown in FIG. 1 has an external shape as shown in FIG.
The water purification tank cartridge 80 is an external part that is detachably coupled to the outside of the switching valve main body 10, and includes a casing (for example, synthetic resin such as ABS resin) 81 and a filter medium (not shown) built in the casing 81. For example, the casing 81 has a purified water outlet 82 (downstream side) and a raw water supply inlet 83 (upstream side).
In general, the purpose of the water purification tank cartridge 80 is to purify the tap water (raw water) by flowing through, but in order to add minerals to the purified water (purified water), mineral additives and the like are also added to the filter medium. In some cases.
And the filter medium has the limit (life) in the ability to purify, and it is necessary to exchange and use the water purification tank cartridge 80 regularly.
Moreover, the water tank cartridge 80 is good to change the capacity | capacitance of a filter medium, a structural ratio, etc. according to the process flow rate of the tap water (raw water) to carry out flow purification, or to change the shape (large or small) of this casing 81.

As shown in FIG. 1 or FIG. 6, the switching valve main body upper cover (for example, synthetic resin such as ABS resin) 70 penetrates the inlet 11 of the switching valve main body 10 and covers the upper part of the switching valve main body 10. Is.
The switching valve main body upper cover 70 is provided with a water discharge mode display window 71 so as to know which water discharge mode is currently selected from the three water discharge modes of straight raw water discharge / shower raw water discharge / purified water discharge.

  As shown in FIG. 5 or FIG. 6, the switching valve main body (for example, synthetic resin such as POM resin) 10 has an inlet 11 into which raw water (tap water) flows from a tap and a camshaft 30 inserted therein. The camshaft bearing hole 12 that bears one end 31 of 30 and the other end at one end (upstream side) of the valve seat T13a (the end surface is slightly tapered so that the abutting O-ring T44a is not damaged). The flow line T13, which is the opening 13b that communicates with the straight water outlet 76 of the switching valve main body lower cover 75 (downstream side), and the valve seat S14a (the end face abuts on the O-ring S44b) are damaged. The other end (downstream side) of the switching valve main body lower cover 75 and the one end (upstream side) of the flow pipe S14 which is an opening 14b leading to the raw shower water outlet 77 of the switching valve body lower cover 75. But The raw water supply outlet 15b is connected to the raw water supply inlet 84 of the water purification tank cartridge 80 at the other end (downstream side) at the seat J15a (the end surface is slightly tapered so that the abutting O-ring J44c is not damaged). A distribution pipe J15, a drive gear shaft 19 on the outer periphery, and a support shaft on which one end (small recess) 51 of the switching lever 50 is rotatably engaged on the opposite side of the drive gear shaft 19 on the axis. (Convex portion) 59.

Usually, water faucet fixing parts are arranged on the upstream side of the inflow port 11. (With water faucet fixing parts, the industry has established uniform standards and sells general-purpose water supply parts. Use them as much as possible to improve maintainability.)
As shown in FIG. 1 or FIG. 6, in the switching valve body 10 of the water faucet direct-coupled water purifier 90 according to one embodiment of the present invention, 60 mesh is used to prevent foreign matter (for example, insects, sand, iron scraps, etc.) from being mixed. Commercially available filters (not shown. For example, polyester net, nylon net, antibacterial metal-added synthetic resin net, stainless steel net, copper net, copper-silver alloy net, aluminum net, antibacterial metal-added metal Nets, nonwoven fabric nets, antibacterial metal-impregnated nonwoven fabric nets, etc. In addition, antibacterial metals include silver, copper, etc., and any processing methods such as adhesion, addition, inclusion, coating, plating, vapor deposition, etc. may be used. A commercially available watertight packing 72 (for example, a doughnut-shaped thick rubber plate), a commercially available faucet fixing part 73 (for example, a 16 mm diameter C ring plate made of POM resin), and a threaded inlet 11 can be screwed. Rotating ring 7 (E.g., synthetic resin such as POM resin) was used and the like.

As shown in FIG. 1 or FIG. 6, outside of the switching valve body 10, it moves in one direction up and down with fingers and reciprocates so as to be restored to the original position after operation. A switching lever (for example, synthetic resin such as ABS resin) 50 for switching three water discharging modes (the switching order is determined by design) is disposed.
The switching lever 50 is substantially U-shaped, and one end (small recess, slot) 51 is rotatably engaged with a support shaft (convex portion) 59 of the switching valve body 10 and the other end (large recess). (Slot) 52 is engaged (directly connected) with the rack 22 (projection).

As shown in FIG. 6, the drive gear shaft 19 of the switching valve body 10 has a ratchet mechanism and a switching lever restoring mechanism, and a driving gear that rotates in one direction (for example, synthetic resin such as ABS resin, switching lever) 50 is rotated 40 degrees in one reciprocating motion of 50.) 20 is pivotally attached. Further, the switching lever 50 is indirectly connected to the drive gear 20.
In the drive gear shaft 19, for example, characters of raw water / shower / purified water are provided on the outer peripheral portion so that it can be understood which of the three water discharge modes is currently selected, ie, straight raw water spouting / shower raw water spouting / purified water spouting. The gear 56 of the display drum 55 displayed on is engaged. The display drum 55 rotates in the reverse direction to the drive gear 20. The characters displayed on the display drum 55 are visible from the water discharge mode display window 71 of the switching valve main body upper cover 70.

The ratchet mechanism and the switching lever restoring mechanism can basically be achieved by well-known techniques. However, in the water tap 90 directly connected water purifier 90 according to one embodiment of the present invention, a click spring (reverse rotation prevention claw. For example, a stainless steel plate. ) 21 and a rack (rotating hook claw. The switching lever 50 is directly connected.

For example, a stainless steel plate) 24.
The switching lever return spring 23 has one end hooked to the rack 22 and the other end hooked to the spring hook plate 24.
When the switching lever 50 is pushed downward with fingers, the rack 22 rotates in one direction in conjunction with it, but stops at a position where the switching lever 50 rotates 40 degrees due to the spring hook plate 24. Since the plurality of claws 27 of the rack 22 are hooked on the positive rotation latching teeth 26 provided on the drive gear 20, the drive gear 20 also rotates while pushing up the click spring 21 in conjunction with the rotation of the rack 22, A biasing (repulsive) force is applied to the switching lever return spring 23.
Here, when the finger is released from the switching lever 50, the switching lever 50 is restored upward by the urging (repulsive) force of the switching lever return spring 23. The rack 22 rotates in the other direction in conjunction with each other, but the claw portion of the click spring 21 is hooked on the reverse rotation prevention tooth 25 of the drive gear 20 to suppress the rotation in the other direction. Slides on a positive rotation latch 26 provided on the drive gear 20, and the drive gear 20 remains stopped in place.
The ratchet mechanism may be a known one-way clutch mechanism.

Rotating motion 60 degrees with respect to the rotational motion) 39, and a cam having two substantially convex portions in an elliptical shape in the axial circumferential direction at a substantially central portion (between the one end portion 31 and the other end portion 32). T33, cam S34, and cam J35 were formed with their phases shifted (for example, 60 degrees and 120 degrees).
As shown in FIG. 5 or FIG. 6, the camshaft 30 is inserted from the camshaft bearing hole 12 of the switching valve body 10, and the one end 31 is supported by the camshaft bearing hole 12. The one end portion 31 has a packing groove 36, and an O-ring (for example, a soft elastic member such as nitrile rubber, silicon rubber, or fluorine rubber) 37 is provided in the packing groove 36 to be watertight.
When the switching lever 50 is pushed down with a finger, the drive gear 20 is rotated 40 degrees in conjunction with it. Then, the display drum 55 is rotated 120 degrees in conjunction with the drive gear 20. Further, the driven gear 39 is rotated 60 degrees in conjunction with the drive gear 20.
When the reciprocating motion of the switching lever 50 is performed three times, the display drum 55 is rotated once (the characters of raw water / shower / purified water are displayed and returned to the original position), and the drive gear 20 is divided into three minutes. And the driven gear 39 is rotated halfway. That is, when the reciprocating motion of the switching switching lever 50 is performed nine times, the display drum 55 is rotated three times, the driving gear 20 is rotated one time, and the driven gear 39 is rotated one and a half times.

As shown in FIG. 3 to FIG. 4 or FIG. 6, one link (for example, synthetic resin such as POM resin) 40 is provided on the camshaft 30 and is an outer peripheral portion of a cam (cam T33, cam S34, cam J35).

A stress of about 0.5 N is applied. Further, the guide receiver 60 is subjected to a stress that is about half (1.5 N) of the sum (about 3 N) of the three repulsive forces of the coil spring 47.
In each of the link T40a, the link S40b, and the link J40c, the convex portion of the rotating cam (cam T33, cam S34, cam J35) and the link (link T40a corresponding to the cam T33, link S40b corresponding to the cam S34) , The valve body T45a, the valve body S45b, and the valve body J45c when the projection of the link J40c) corresponding to the cam J35 is not slid on the valve seat T13a and the valve body S45b facing the valve body T45a. The valve seat S14a and the valve seat J15a facing the valve body J45c are reliably closed with a stress of about 0.5 N (valve body and valve seat) at low water pressure (for example, 0.05 to 0.10 MPa). To prevent the raw water from entering the distribution pipe).

Here, for example, a case is assumed in which the convex portion of the cam T33 is in contact with the protrusion of the link T40a corresponding to the cam T33. That is, the convex portion of the cam S34, the protruding portion of the link S40b corresponding to the cam S34, but not in contact with, also, the convex portion of the cam J35, the protruding portion of the link J 40c corresponding to the cam J35, but This is the case where they are not in contact. The camshaft 30 at this time is only subjected to about 0.5 N of the stress that lifts the link T40a (stress that the link T40a receives by the coil spring 47). (No stress is received from the link S40b and the link J40c.)
When the switching lever 50 is pushed downward with a finger, the drive gear 20 rotates in one direction at a constant angle, and the driven gear 39 interlocked with the drive gear 20 moves in the other direction at a constant angle. When the camshaft 30 rotates at a certain angle by rotating the cam T30, the projection of the cam T33 and the protrusion of the link T40a corresponding to the cam T33 slide down to lower the link T40a. , for example, pushes the convex portion of the cam S34, the protruding portion of the link S 40b corresponding to the cam S34, the link S 40b but in contact with the sliding.
Explaining mechanically, the camshaft 30 is originally rotated with a force proportional to the force that pushes the switching lever 50 downward with fingers, but when the link T40a is lowered, the stress (about approximately) applied to the link T40a. 0.5N) is also added to rotate the cam T33 (camshaft 30). Further, the link S 40b corresponding to the cam S34 is pushed up by the rotating added stress. In other words, because of the lever principle, the force that pushes the switching lever 50 downward with fingers does not require the force to push up the link (about 0.5 N), so the camshaft 30 with no load is rotated. This means that it is only necessary to have the equivalent power. This is the effect of the coil spring 47.
Due to the effect of the coil spring 47, it is possible to switch easily and surely with a one-touch operation with a small operating force of the switching lever 50 for switching between three water discharge modes such as straight raw water discharge / shower raw water discharge / purified water discharge. It is something that can be done.

As shown in FIG. 5 or FIG. 6, the switching valve main body lower cover (for example, synthetic resin such as ABS resin) 75 is a straight raw water outlet that is coupled to the opening 13 b of the flow pipe T <b> 13 of the switching valve main body 10. 76, a raw shower water outlet 77 connected to the opening 14b of the flow passage S14 of the switching valve main body 10, and a switching lever stopper 78.
The switching valve main body lower cover 75 has an opening 13b (downstream side) of the flow conduit T13 of the switching valve main body 10 coupled to the straight raw water discharge port 76, and an opening of the flow conduit S14 of the switching valve main body 10. 14 b (downstream side) covers the lower part of the switching valve main body 10 while being coupled with the shower raw water outlet 77.
The switching lever stopper 78 is a rotation stopper when the switching lever 50 is pushed downward with a finger. For example, when the switching lever 50 is pushed downward with a thumb, the switching lever stopper 78 is switched with a finger other than the thumb. If the switching lever 50 is pushed downward so as to support the back surface of the lever topper 78, the force of the thumb can be easily applied.
The switching valve body upper cover 70 and the switching valve body lower cover 75 are assembled by sandwiching the switching valve body 10. At the same time, one end (small concave portion) 51 of the switching lever 50 becomes non-detachable while being kept rotatable.

The operation (software) of the water faucet direct-coupled water purifier 90 according to one embodiment of the present invention will be described.
Although part of the reference numerals is omitted in FIG. 5, the rectifying blade T43a of the valve body T45a is inserted into the valve seat T13a. The straightening blade S43b of the valve body S45b is inserted into the valve seat S14a. The straightening blade J43c of the valve body J45c is inserted into the valve seat J15a.
The O-ring T44a of the valve body T45a is disposed so as to press and close the valve seat T13a. The O-ring S44b of the valve body S45b is disposed so as to press and close the valve seat S14a. The O-ring J44c of the valve body J45c is disposed so as to press and close the valve seat J15a.
The drive gear 20 rotates in one direction at a constant angle by one reciprocating motion of the switching lever 50 with the fingers, and the driven gear 39 interlocked with the drive gear 20 rotates in the other direction at a constant angle. As a result, the cam shaft 30 rotates at a constant angle, and any one of the convex portions of the cam T33, the cam S34, and the cam J35 corresponds to the link T40a, the link S40b, and the link J40c. Any one of the link T40a, the link S40b, and the link J40c is reciprocated in the vertical direction by sliding with the protruding portion. Accordingly, the corresponding valve body T45a opens or closes the valve seat T13a, the valve body S45b opens or closes the valve seat S14a, and the valve body J45c opens or closes the valve seat J15a. Operate.
The raw water in the switching valve main body 10 passes through either the flow pipe T13, the flow pipe S14 or the flow pipe J15, and the straight raw water discharge port 76 of the switching valve main body lower cover 75 or under the switching valve main body. The water is passed through either the shower raw water outlet 77 of the cover 75 or the purified water outlet 82 of the water purification tank cartridge 80.
Then, by repeating one up and down reciprocation by the finger of the switching lever 50, the three water discharge modes of the straight raw water spouting / shower raw water spouting / purified water spouting are switched one after another and discharged.

  FIG.7 (b) is a perspective view of the water tank cartridge 180 couple | bonded with the water tap direct connection type water purifier 91 of the other Example of this invention. FIG. 8 is a perspective view of a water tap-direct water purifier 91 according to another embodiment of the present invention. FIG. 9 is a front sectional view of a main part of a water tap direct-coupled water purifier 91 according to another embodiment of the present invention when the camshaft 30 is cut as a center. FIG. 10 is an isometric view showing the main components of a water faucet direct-coupled water purifier 91 according to another embodiment of the present invention.

With reference to FIG. 8 thru | or FIG. 10 and FIG.7 (b), the structure (hardware) of the water faucet direct connection type water purifier 91 of the other Example of this invention is demonstrated.
As an example, a water purification tank cartridge 180 having an external shape as shown in FIG. 7 (b) is an accessory part that is built into the water faucet direct-coupled water purifier 91 according to another embodiment of the present invention and is detachably coupled. A casing (for example, synthetic resin such as ABS resin) 181 and a filter medium (not shown; for example, activated carbon, hollow fiber membrane filter) incorporated in the casing 181, and a water purification outlet is provided outside the casing 181. 182 (downstream side) and raw water supply inlet 183 (upstream side).
In general, the purpose of the water purification tank cartridge 180 is to purify the tap water (raw water) through flow, but in order to add minerals to the purified water (purified water), mineral additives and the like are also added to the filter medium. In some cases.
And the filter medium has a limit (life) in the ability to purify, and it is necessary to periodically replace and use the water purification tank cartridge 180.
In addition, since the water purification tank cartridge 180 is an accessory part built in the water faucet direct connection type water purifier 91 according to another embodiment of the present invention, the shape (large or small) of the casing 181 cannot be easily changed, but the flow purification is performed. Depending on the treatment flow rate of tap water (raw water), it is possible to change the capacity, composition ratio, etc. of the filter medium.

As shown in FIG. 8 or FIG. 10, the switching valve body upper cover (for example, synthetic resin such as ABS resin) 170 penetrates the inlet 11 of the switching valve body 10 and covers the upper part of the switching valve body 10. Is.
The switching valve main body upper cover 170 is provided with a water discharge mode display window 171 so as to know which water discharge mode is currently selected from the three water discharge modes of straight raw water discharge / shower raw water discharge / purified water discharge.
A water purification tank cartridge lid (for example, synthetic resin such as ABS resin) 172 is attached to an opening 173 formed when the switching valve main body upper cover 170 and the switching valve main body lower cover 175 are combined. The water purification tank cartridge 180 is accommodated in the opening 173.

As shown in FIG. 9 or FIG. 10, the switching valve body (for example, synthetic resin such as POM resin) 10 (used in common with the water faucet directly connected water purifier 90 of one embodiment of the present invention) Tap water), the camshaft bearing hole 12 into which the camshaft 30 is inserted to support one end 31 of the camshaft 30, and the one end (upstream side) of the valve seat T13a (the end surface abuts). A ring T44a is slightly tapered so that the other end (downstream side) is an opening 13b leading to the straight water outlet 176 of the switching valve main body lower cover 175, and one end. (Upstream side) is the valve seat S14a (the end surface is slightly tapered so that the abutting O-ring S44b is not damaged), and the other end portion (downstream side) is the shower raw water outlet 1 of the switching valve main body lower cover 175. 7 is an opening 14b leading to 7 and one end (upstream side) of the valve seat J15a (the end surface is slightly tapered so that the abutting O-ring J44c is not damaged). The downstream side) is a flow passage J15 which is a raw water supply outlet 15b coupled to the raw water supply inlet 184 of the water purification tank cartridge 180, a drive gear shaft 19 on the outer periphery, and an opposite side on the axis of the drive gear shaft 19 Has a support shaft (convex portion) 59 with which one end (small concave portion) 51 of the switching lever 50 is rotatably engaged.
Further, the switching valve body 10 has a raw water supply connection inlet 16a having one end (upstream side) coupled to the raw water supply outlet 15b of the flow pipe J15 and the other end (downstream side) raw water of the water purification tank cartridge 180. The raw water supply connection outlet 16b connected to the supply inlet 183 is a flow pipe Y16 and one end (upstream side) is a purified water inlet 17a connected to the purified water outlet 182 of the water purification tank cartridge 180, and the other end (downstream side) is connected. A combined flow conduit unit 18 having a flow conduit Z17 that is an opening 17b that communicates with the purified water outlet 179 of the switching valve main body lower cover 175 is coupled.

Usually, water faucet fixing parts are arranged on the upstream side of the inflow port 11. (With water faucet fixing parts, the industry has established uniform standards and sells general-purpose water supply parts. Use them as much as possible to improve maintainability.)
As shown in FIG. 8 or FIG. 10, in the switching valve main body 10 of the water faucet direct-coupled water purifier 91 according to another embodiment of the present invention, 60 mesh is used to prevent foreign matter (for example, insects, sand, iron scraps, etc.) from being mixed. Commercially available filters (not shown. For example, polyester net, nylon net, antibacterial metal-added synthetic resin net, stainless steel net, copper net, copper-silver alloy net, aluminum net, antibacterial metal-added metal Nets, nonwoven fabric nets, antibacterial metal-impregnated nonwoven fabric nets, etc. In addition, antibacterial metals include silver, copper, etc., and any processing methods such as adhesion, addition, inclusion, coating, plating, vapor deposition, etc. may be used. A commercially available watertight packing 72 (for example, a doughnut-shaped thick rubber plate), a commercially available faucet fixing part 73 (for example, a 16 mm diameter C ring plate made of POM resin), and a threaded inlet 11 can be screwed. Rotating ring 4 (e.g., synthetic resin such as POM resin) was used and the like.

As shown in FIG. 8 or FIG. 10, outside the switching valve main body 10, it moves in one direction up and down with fingers and reciprocates so as to restore to the original position after the operation, so that straight raw water spouting / shower raw water spouting / Switching lever (for example, synthetic resin such as ABS resin) 50 for switching the three water discharge modes (the switching order is determined by design) 50 (common to the water tap 90 directly connected water purifier 90 of one embodiment of the present invention) Use) is arranged.
The switching lever 50 is substantially U-shaped, and one end (small concave portion) 51 is rotatably engaged with a support shaft (convex portion) 59 of the switching valve body 10 and the other end (large concave portion, slot). 52 is engaged (directly connected) to the rack 22 (convex portion).

As shown in FIG. 10, the drive gear shaft 19 of the switching valve body 10 has a ratchet mechanism and a switching lever restoring mechanism that are used in common with the water faucet direct-coupled water purifier 90 of one embodiment of the present invention. A drive gear 20 that rotates in the direction (for example, synthetic resin such as ABS resin, rotates 40 degrees in one reciprocating movement of the switching lever 50) 20 is attached to the shaft. Further, the switching lever 50 is indirectly connected to the drive gear 20.
In the drive gear shaft 19, for example, characters of raw water / shower / purified water are provided on the outer peripheral portion so that it can be understood which of the three water discharge modes is currently selected, ie, straight raw water spouting / shower raw water spouting / purified water spouting. The gear 56 of the display drum 55 displayed on is engaged. The display drum 55 rotates in the reverse direction to the drive gear 20. The characters displayed on the display drum 55 are visible from the water discharge mode display window 171 of the switching valve main body upper cover 170.

The ratchet mechanism and the switching lever restoring mechanism can basically be achieved by well-known techniques. However, in the water faucet direct connection type water purifier 91 according to another embodiment of the present invention, a click spring (reverse rotation preventing claw. For example, a stainless steel plate. ) 21 and a rack (rotating hook claw. The switching lever 50 is directly connected. For example, a synthetic resin such as POM resin) 22 and a reverse rotation in which a claw portion of the click spring 21 can be hooked and slid on one end face. A drive gear 20 having a preventive tooth 25 and a forward rotation latching tooth 26 on which the plurality of claws 27 of the rack 22 can be latched and slid on the other end surface, a switching lever return spring (for example, stainless steel wire) 23, a spring And a hanging plate (a 40-degree rotation limiting plate of the switching lever 50. For example, a stainless steel plate) 24.
The switching lever return spring 23 has one end hooked to the rack 22 and the other end hooked to the spring hook plate 24.
When the switching lever 50 is pushed downward with fingers, the rack 22 rotates in one direction in conjunction with it, but stops at a position where the switching lever 50 rotates 40 degrees due to the spring hook plate 24. Since the plurality of claws 27 of the rack 22 are hooked on the positive rotation latching teeth 26 provided on the drive gear 20, the drive gear 20 also rotates while pushing up the click spring 21 in conjunction with the rotation of the rack 22, A biasing (repulsive) force is applied to the switching lever return spring 23.
Here, when the finger is released from the switching lever 50, the switching lever 50 is restored upward by the urging (repulsive) force of the switching lever return spring 23. The rack 22 rotates in the other direction in conjunction with each other, but the claw portion of the click spring 21 is hooked on the reverse rotation prevention tooth 25 of the drive gear 20 to suppress the rotation in the other direction. Slides on a positive rotation latch 26 provided on the drive gear 20, and the drive gear 20 remains stopped in place.
The ratchet mechanism may be a known one-way clutch mechanism.

Since the camshaft is used in common with the water faucet direct connection type water purifier 90 of one embodiment of the present invention, a part of the explanation will be described with reference to FIG.
As shown in FIG. 2, the camshaft (for example, synthetic resin such as POM resin) 30 is engaged with the drive gear 20 on one end 31 side and rotates in the other direction (for example, 40 degrees of the drive gear 20). Rotating motion 60 degrees with respect to the rotational motion) 39, and a cam having two substantially convex portions in an elliptical shape in the axial circumferential direction at a substantially central portion (between the one end portion 31 and the other end portion 32). T33, cam S34, and cam J35 were formed with their phases shifted (for example, 60 degrees and 120 degrees).
As shown in FIG. 9 or 10, the camshaft 30 is inserted from the camshaft bearing hole 12 of the switching valve main body 10, and the one end portion 31 is supported by the camshaft bearing hole 12. The one end portion 31 has a packing groove 36, and an O-ring (for example, a soft elastic member such as nitrile rubber, silicon rubber, or fluorine rubber) 37 is provided in the packing groove 36 to be watertight.
When the switching lever 50 is pushed down with a finger, the drive gear 20 is rotated 40 degrees in conjunction with it. Then, the display drum 55 is rotated 120 degrees in conjunction with the drive gear 20. Further, the driven gear 39 is rotated 60 degrees in conjunction with the drive gear 20.
This is because, when the reciprocating motion of the switching lever 50 is performed three times, the display drum 55 rotates once (the characters of raw water / shower / purified water are displayed and returned to the original position), and the drive gear 20 is reduced to a third. Then, the driven gear 39 is rotated halfway. That is, when the reciprocating motion of the switching lever 50 is performed nine times, the display drum 55 is rotated three times, the driving gear 20 is rotated one time, and the driven gear 39 is rotated one and a half times.

Since the link is used in common with the water faucet direct-coupled water purifier 90 according to one embodiment of the present invention, a part of the link will be described with reference to FIGS.
As shown in FIG. 3 to FIG. 4 or FIG. 10, one link (for example, synthetic resin such as POM resin) 40 is provided on the camshaft 30 and is an outer peripheral portion of a cam (cam T33, cam S34, cam J35). The open / close valve main body has a hollow portion 41 formed so as to surround the hollow portion 41, and one protrusion 42 is formed on the hollow portion 41 side.
The link 40 linearly reciprocates in the vertical direction by sliding between the projecting portions of the rotating cams (cam T33, cam S34, and cam J35) and the projections 42.
In a water faucet direct-coupled water purifier 91 according to another embodiment of the present invention, a link T40a corresponding to the cam T33 of the camshaft 30 and a link S40b corresponding to the cam S34 correspond to the cam J35. The links J40c are arranged so as to respond to each other.

In addition, a valve body (plug) having a rectifying blade 43 and an O-ring (for example, a soft elastic member such as nitrile rubber, silicon rubber, fluorine rubber) 44 at one end portion (downstream side) of the outer peripheral portion of the link 40. 45) is provided.
The valve body corresponding to the valve seat T13a (upstream side) of the switching valve body 10 is the valve body T45a (rectifying blade T43a, O-ring T44a), and the valve body corresponding to the valve seat S14a (upstream side) is the valve body S45b ( In the rectifying blade S43b and the O-ring S44b), the valve body corresponding to the valve seat J15a (upstream side) is the valve body J45c (rectifying blade J43c, O-ring J44c).

Since the coil spring and the guide receiver are used in common with the water faucet direct-coupled water purifier 90 of one embodiment of the present invention, a part of the explanation will be described with reference to FIG.
A shaft-shaped guide 46 is provided at the other end (upstream side) of the outer periphery of the link 40, and a coil spring (for example, stainless steel wire) 47 is provided at the outer periphery of the guide 46. It has been.
The link T40a corresponds to the guide T46a, the link S40b corresponds to the guide S46b, and the link J40c corresponds to the guide J46c.
As shown in FIGS. 4 and 9 to 10, the guide T46a, the guide S46b, and the guide J46c can be slid simultaneously on the upper portions of the guide T46a, the guide S46b, and the guide J46c. One guide receiver (for example, synthetic resin such as POM resin) 60 to be supported is provided.
In the guide receiver 60, the raw water passage port 61, a guide hole 62a into which the guide T46a is inserted, a guide hole 62b into which the guide S46b is inserted, and the guide J46c are inserted at an arbitrary position in a substantially central portion. The guide hole 62c and the recessed part 63 which bears the other end part 32 of the camshaft 30 are provided.
In addition, a filter (not shown), a watertight packing 72, a faucet fixing component 73, and the like are placed on the upper portion (upstream side) of the guide receiver 60.

The effect of the coil spring 47 that constantly urges and urges each of the link T40a, the link S40b, and the link J40c will be described.
Since each of the link T40a, the link S40b, and the link J40c has a repulsive force of the coil spring 47 of, for example, about 1N, the guide receiver 60 receives about half of the stress of about 1N. A stress of about 0.5 N is applied. Further, the guide receiver 60 is subjected to a stress that is about half (1.5 N) of the sum (about 3 N) of the three repulsive forces of the coil spring 47.
In each of the link T40a, the link S40b, and the link J40c, the convex portion of the rotating cam (cam T33, cam S34, cam J35) and the link (link T40a corresponding to the cam T33, link S40b corresponding to the cam S34) , The valve body T45a, the valve body S45b, and the valve body J45c when the projection of the link J40c) corresponding to the cam J35 is not slid on the valve seat T13a and the valve body S45b facing the valve body T45a. The valve seat S14a and the valve seat J15a facing the valve body J45c are reliably closed with a stress of about 0.5 N (valve body and valve seat) at low water pressure (for example, 0.05 to 0.10 MPa). To prevent the raw water from entering the distribution pipe).

Here, for example, a case is assumed in which the convex portion of the cam T33 is in contact with the protrusion of the link T40a corresponding to the cam T33. That is, the convex portion of the cam S34, the protruding portion of the link S40b corresponding to the cam S34, but not in contact with, also, the convex portion of the cam J35, the protruding portion of the link J 40c corresponding to the cam J35, but This is the case where they are not in contact. The camshaft 30 at this time is only subjected to about 0.5 N of the stress that lifts the link T40a (stress that the link T40a receives by the coil spring 47). (No stress is received from the link S40b and the link J40c.)
When the switching lever 50 is pushed downward with a finger, the drive gear 20 rotates in one direction at a constant angle, and the driven gear 39 interlocked with the drive gear 20 moves in the other direction at a constant angle. When the camshaft 30 rotates at a certain angle by rotating the cam T30, the projection of the cam T33 and the protrusion of the link T40a corresponding to the cam T33 slide down to lower the link T40a. , for example, pushes the convex portion of the cam S34, the protruding portion of the link S 40b corresponding to the cam S34, the link S 40b but in contact with the sliding.
Explaining mechanically, the camshaft 30 is originally rotated with a force proportional to the force that pushes the switching lever 50 downward with fingers, but when the link T40a is lowered, the stress (about approximately) applied to the link T40a. 0.5N) is also added to rotate the cam T33 (camshaft 30). Further, the link S 40b corresponding to the cam S34 is pushed up by the rotating added stress. In other words, because of the lever principle, the force that pushes the switching lever 50 downward with fingers does not require the force to push up the link (about 0.5 N), so the camshaft 30 with no load is rotated. This means that it is only necessary to have the equivalent power. This is the effect of the coil spring 47.
Due to the effect of the coil spring 47, it is possible to switch easily and surely with a one-touch operation with a small operating force of the switching lever 50 for switching between three water discharge modes such as straight raw water discharge / shower raw water discharge / purified water discharge. It is something that can be done.

As shown in FIG. 9 or 10, the switching valve main body lower cover (for example, synthetic resin such as ABS resin) 175 is a straight raw water outlet that is coupled to the opening 13 b of the flow pipe T <b> 13 of the switching valve main body 10. 176, the raw raw water outlet 177 coupled to the opening 14b of the flow conduit S14 of the switching valve body 10, and the purified water coupled to the opening 17b of the flow conduit Z17 of the combined flow conduit unit 18 A water discharge port 179 and a switching lever stopper 178 are provided.
The switching valve main body lower cover 175 has an opening 13b (downstream side) of the flow conduit T13 of the switching valve main body 10 coupled to the straight raw water outlet 176, and an opening of the flow conduit S14 of the switching valve main body 10. 14 b (downstream side) is connected to the raw shower water discharge port 177, and the opening 17 b of the flow line Z 17 of the combined flow line unit 18 covers the lower part of the switching valve body 10 while being connected to the purified water discharge port 179. Is.
The switching lever stopper 178 is a rotation stopper when the switching lever 50 is pushed downward with a finger. For example, when the switching lever 50 is pushed downward with a thumb, the switching lever stopper 178 is switched with a finger other than the thumb. If the switching lever 50 is pushed downward so as to support the reverse side of the lever stopper 178, the thumb force can be easily applied.
The switching valve body upper cover 170 and the switching valve body lower cover 175 are assembled by sandwiching the switching valve body 10. At the same time, one end (small concave portion) 51 of the switching lever 50 becomes non-detachable while being kept rotatable.

The operation (software) of the water tap-direct water purifier 91 according to another embodiment of the present invention will be described.
Although part of the reference numeral is omitted in FIG. 9, the rectifying blade T43a of the valve body T45a is inserted into the valve seat T13a. The straightening blade S43b of the valve body S45b is inserted into the valve seat S14a. The straightening blade J43c of the valve body J45c is inserted into the valve seat J15a.
The O-ring T44a of the valve body T45a is disposed so as to press and close the valve seat T13a. The O-ring S44b of the valve body S45b is disposed so as to press and close the valve seat S14a. The O-ring J44c of the valve body J45c is disposed so as to press and close the valve seat J15a.
The drive gear 20 rotates in one direction at a constant angle by one reciprocating motion of the switching lever 50 with the fingers, and the driven gear 39 interlocked with the drive gear 20 rotates in the other direction at a constant angle. As a result, the cam shaft 30 rotates at a constant angle, and any one of the convex portions of the cam T33, the cam S34, and the cam J35 corresponds to the link T40a, the link S40b, and the link J40c. Any one of the link T40a, the link S40b, and the link J40c is reciprocated in the vertical direction by sliding with the protruding portion. Accordingly, the corresponding valve body T45a opens or closes the valve seat T13a, the valve body S45b opens or closes the valve seat S14a, and the valve body J45c opens or closes the valve seat J15a. Operate.
A route through which the raw water in the switching valve body 10 passes through the flow pipe T13, the flow pipe S14, the flow pipe J15, the flow pipe Y16, the water purification tank cartridge 180, and the flow pipe Z17.
