[Implement a new style]

Hereinafter, the implementation aspects will be described in detail with reference to appropriate drawings. Furthermore, in the following terms, from the standpoint of distinguishing the liquid from the hot water supply hole and the liquid from the cold water supply hole, "cold water" and "hot water" are used respectively to meet the needs. However, on the other hand, there is also a description that the liquid from the hot water supply hole and the liquid from the cold water supply hole are collectively referred to as "water".

In this application, taking into account the usual usage conditions in the implementation mode, the terms "up", "down", "upside", "downside", etc. are used. The posture of the faucet can be changed according to the state of use, the specifications of the faucet, the specifications of the equipment to which the faucet is installed, etc.; in this case, the aforementioned terms can be appropriately explained according to the posture of the faucet.

Unless otherwise specified, the "radial direction" in this application refers to the radial direction of the upper shell. Unless otherwise specified, the "circumferential direction" in this application refers to the circumferential direction of the upper shell.

FIG. 1 is a perspective view of a cold and hot water mixing faucet 10 related to an embodiment. The cold and hot water mixing faucet 10 has a faucet body 12, a lever handle 14, a water outlet part 16, a hot water inlet pipe 18, a cold water inlet pipe 20 and a water outlet pipe 22.

In this embodiment, as the lever handle 14 moves upward, the amount of water output will increase; when the lever handle 14 moves to the lowermost side, the water will stop; regardless of the left and right positions of the lever, when the lever handle 14 is at the lowest When it is in position, the water will stop. Conversely, the lever handle 14 can also move downwards, and the amount of water Just increase. By turning the control lever handle 14 left and right, the mixing ratio of hot water and cold water is changed; therefore, the temperature of the outlet water is adjusted by the left and right positions of the control lever. In addition, the movement of the control lever handle 14 when adjusting the water discharge amount is not forward and backward rotation but up and down rotation; however, the movement of the tilt control lever 46 accompanying this rotation of the control lever handle 14 is forward and backward rotation. Therefore, from the viewpoint of uniform terminology and easy understanding, in this application, the aforementioned rotation of the lever handle 14 is referred to as forward and backward rotation.

Figures 2(a) and 2(b) are perspective views of the valve assembly 38. Figure 2(a) is a perspective view in a water-stop state; Figure 2(b) shows the state of maximum water output "maximum water output state".

As the lever handle 14 rotates left and right, the tilt control lever 46 also rotates left and right. The rotating body 44 and the tilt control lever 46 rotate together, and the movable valve body 60 also rotates. As the tilt lever 46 rotates left and right, the lever sealing member 48 also rotates, rotates together with the spherical portion 52, and does not slide together with the spherical portion 52. Furthermore, the lever sealing member 48 may not rotate along with the left and right rotation of the tilt lever 46. At each left and right position of the control lever, the spherical portion 52 is in close contact with the control lever sealing member 48.

In conjunction with the forward and backward rotation of the control lever handle 14, the tilt control lever 46 rotates back and forth; due to the forward and backward rotation of the tilt control lever 46, the inclination of the tilt control lever 46 will change. As the tilt lever 46 rotates back and forth, the movable valve body 60 slides relative to the rotating body 44; as the tilt lever 46 rotates back and forth, the lever sealing member 48 slides on the spherical portion 52.

By rotating the tilt control lever 46 back and forth, the inclination of the tilt control lever 46 changes. In this application, the front and rear positions of the tilt control rod 46 that change due to the inclination of the tilt control rod 46 are also collectively referred to as the tilt position of the control rod. At all the tilt positions of the control lever, the control lever sealing member 48 is in close contact with the spherical portion 52.

In this embodiment, the click revolving body 56 is a structure in which a plurality of components are combined; the click revolving body 56 has a metal member 190 and a resin member 192. The resin member 192 has a right side resin member 192a and a left side resin member 192b; the right side resin member 192a and the left side resin member 192b have a mirror image relationship with each other. The click revolving body 56 can also be made into an integrally formed structure.

Furthermore, in this application, "right side" and "left side" are only used to distinguish the parts located on both sides of the tilt lever 46 from each other; "right side" and "left side" are not absolute Meaning, but use it in a relative sense.

8(a) and 8(b) are perspective views of the metal member 190. Fig. 8(a) is a perspective view viewed diagonally above; Fig. 8(b) is a perspective view viewed diagonally below.

The metal member 190 is entirely made of plate material. The metal member 190 has the aforementioned base portion 162 and the cylindrical forming portion 164; the metal member 190 has a downward extending portion 168; and the metal member 190 has the first click joint portion 170.

Although not shown in the figure, the right resin member 192a has a slit with a vertical gap. The base 162 of the metal member 190 is inserted into the slit. As a result, the base 162 of the metal member 190 is nipped. Into the right resin member 192a. Also, insert a metal structure into the wall of this slit The piece 190 engages the convex portion 194. With this structure, the right resin member 192a is fixed to the metal member 190; the left resin member 192b is also fixed to the metal member 190 in the same way.

The click slewing body 56 like this is covered on the cylindrical part "small diameter cylindrical part 120" made into the upper part of the upper shell 42 "refer to Figure 2 (a), Figure 2 (b), Figure 3 (b) ) And Figure 4(b)". The base 162 of the click revolver 56 is placed on the small-diameter cylindrical portion 120; the cylindrical forming portion 164 of the click revolver 56 is arranged on the outside of the small-diameter cylindrical portion 120 along the small-diameter cylindrical portion 120; The cylinder forming portion 164 is guided by the small-diameter cylinder portion 120, and the rotary body 56 is clicked to rotate. The center of rotation of the click slewing body 56 is the same as the center line of the upper shell 42 "small diameter cylindrical portion 120"; the tilt control rod 46 passes through the center opening 166 of the click slewing body 56.

When the click revolver 56 rotates, a click joint is produced. As shown in FIG. 2(b) and FIG. 5, the outer peripheral surface of the small-diameter cylindrical portion 120 is provided with a click joint portion 200. The click engaging portion 200 installed on the upper shell 42 is also called a second click engaging portion, and the second click engaging portion 200 is a convex portion. When the click revolver 56 reaches the predetermined rotation position, the second click engagement portion 200 contacts the first click engagement portion 170 of the click revolver 56; when the click revolver 56 is further rotated, the first click engagement portion 170 rides On the second click engaging portion 200; at this time, at the click revolving body 56, the lower extension 168 is elastically deformed; this elastic deformation is a deformation of the click engaging portion 170 being displaced radially outside the cylindrical forming portion 164 When the click revolver 56 is further rotated, the first click engagement portion 170 crosses the second click engagement portion 200. At this time, the aforementioned elastic deformation of the lower extension portion 168 is instantly released, and a click occurs. In this way, a click occurs due to the engagement between the first click joint portion 170 and the click joint portion 200.

This click may have a sound, or a feeling transmitted to the hand holding the joystick handle 14 "vibration, etc.". Ideally, this click includes the sound "click (click)" and vibration. The rotation of the click revolver 56 is generated by the left and right rotation of the tilt lever 46, therefore, this click is called a left and right click; a left and right click conveys the left and right position of the control lever to the user at a specific position.

Furthermore, there is no restriction on the left and right position of the joystick when the left and right click occurs. In the foregoing embodiment, the left and right positions of the control lever when the left and right clicks are generated are slightly off the hot water side of the "less than 10 degree angle" compared to the front position. Click this left and right to inform the user whether hot water is mixed in. The two first click joint parts 170 are operated at the same left and right positions of the lever at the same time, so the click sound becomes louder.

〔Closed structure〕

As shown in FIG. 4(b) etc., the valve assembly 38 has a space S1 around the valve body. In the hot and cold water mixing faucet 10, the space S1 around the valve body is a closed space; the space around the valve body S1 is sealed by a plurality of sealing members; the space around the valve body S1 includes the surrounding of the sliding mating surface PL3 The space around the valve body S1, including the space around the inner seal component (inner seal component) 64; the space around the valve body S1, including the space between the valve assembly 38 and the receiving portion 13; these spaces, by purchasing The gap between them is linked together. The space S1 around the valve body is a space for storing leaked water leaking from the sliding mating surface PL3 and the internal sealing member 64.

The upper side of the space S1 around the valve body is sealed with a lever seal component 48 and an upper seal component 40. The upper end sealing member 40 seals between the upper end housing 42 and the faucet body 12. In this embodiment, the upper sealing member 40 seals between the upper housing 42 "large diameter cylindrical part 122" and the side wall 12a; the control rod sealing member 48 seals the control rod linkage part "spherical part 52" and the upper end Between the housing 42. The upper end sealing member 40 and the control rod sealing member 48 are tied at a position higher than the sliding mating surface PL3; the control rod sealing member 48 located inside the valve assembly 38 and the upper end located outside the valve assembly 38 The sealing member 40 can seal the upper side of the space S1 around the valve body.

The lower side of the space S1 around the valve body is sealed by an inner seal component 64 and a lower seal component 66. The inner sealing member 64 seals between the fixed valve body 62 and the lower case 68; the lower seal component 66 seals between the lower case 68 and the faucet body 12. In this embodiment, the lower end sealing member 66 seals between the lower end housing 68 and the bottom 12b. The inner sealing member 64 and the lower end sealing member 66 are positioned at a position lower than the sliding mating surface PL3; the inner sealing member 64 located inside the valve assembly 38 and the lower end sealing member located outside the valve assembly 38 With the member 66, the sealing of the lower side of the space S1 around the valve body is realized.

In this way, the valve assembly 38 and the accommodating portion 13 of the faucet body 12 are sealed with the upper sealing member 40 on the upper side, and sealed with the lower sealing member 66 on the lower side. Furthermore, the linkage part of the control lever is sealed with a lever seal component 48. Also, the fixed valve body 62 and the lower end shell The body 68 is sealed with an inner seal component 64. With these sealing members, the space S1 around the valve body is sealed.

In a dry sliding type (dry sliding type) hot and cold water mixing faucet 10, it is undesirable for water to flow out from the sliding mating surface PL3. However, water may leak from the sliding mating surface PL3 due to wear, grease outflow, etc.; in addition, due to deterioration, water leakage from each sealing portion also occurs. In a normal dry sliding type hot and cold water mixing faucet, the space S1 around the valve body is not sealed. Therefore, after the leaked water fills the space S1 around the valve body, it overflows the outside of the faucet body 12; the leaked water flows downward along the outer wall of the hot and cold water mixing faucet 10 and is collected at the root of the faucet. The so-called faucet root refers to the boundary between the faucet body 12 and the faucet installation part "Liulitai etc.", and the accumulated water corrodes the faucet root.

In the hot and cold water mixing faucet 10 disclosed in this specification, the space S1 around the valve body is tightly closed, so that leaking water does not flow out to the outside.

Due to the tight closing described above, the space S1 around the valve body is isolated from the outside. Therefore, it is possible to prevent the washing water used when washing the hot and cold water mixing faucet 10 from entering the space S1 around the valve body; Intrusion of detergent. As a result, the outflow of grease is suppressed.

When the temperature of the outlet water is high, the air in the space S1 around the valve body and its surrounding components are heated to expand, and the high air pressure generated by the expansion pushes the movable valve body 60 downward. As a result, when water is discharged, water leakage from the sliding mating surface PL3 is suppressed.

As the leakage water increases, the pressure in the space S1 around the valve body that is tightly closed increases. If the pressure difference between the inside and outside of the sealing member becomes small due to this pressure, water leakage is suppressed. In addition, if this pressure becomes the same as the pressure inside the sealing member, the pressure difference between the inside and the outside of the sealing member is eliminated, and no water leakage occurs. In addition, if the pressure in the space S1 around the valve body rises, the sealing member is compressed from the inside and outside to become thinner and tends to extend in the vertical direction, and the sealing pressure increases. In addition, regarding the water leakage from the sliding fitting surface PL3, if the pressure of the space S1 around the valve body is the same as the water leakage pressure, water leakage can be prevented. In this way, the structure of the tightly closed valve body surrounding space S1 can suppress water leakage due to internal pressure.

The shape of the upper end sealing member 40 is not limited. As in the previous embodiment, when the inner peripheral surface of the side wall 12a and the outer peripheral surface of the upper housing 42 are sealed, the ring-shaped upper end sealing member 40 is more suitable for ideal. This ring seal is exemplified by O-rings and lip packing. In the foregoing embodiment, an O-ring is used.

The shape of the control rod sealing member 48 is not limited. As in the foregoing embodiment, when the spherical portion 52 of the tilting control rod 46 is sealed, the annular control rod sealing member 48 is more desirable.

The shape of the inner sealing member 64 is not limited. As described above, the inner sealing member 64 may be three ring-shaped sealing members as in the foregoing embodiment, or may be an integrally formed piece with three ring-shaped parts. When three separate ring seals are used, each ring seal may also be cylindrical. In the foregoing embodiment, the hot water hole sealing portion 64a, the cold water hole sealing portion 64b, and the discharge hole sealing portion 64c are also cylindrical "refer to FIG. 4". The internal sealing member 64 is compressed and used between the fixed valve body 62 and the lower end housing 68; due to the existence of the internal sealing member 64, a gap is ensured between the fixed valve body 62 and the lower end housing 68; the internal sealing member 64, While maintaining this gap, the fixed valve body 62 is also pressed to the upper "movable valve body 60 side". This pressing force increases the contact pressure on the sliding mating surface PL3 and suppressing water leakage from the sliding mating surface PL3.

The shape of the lower seal component 66 is not limited. The lower seal component 66 may also be three annular seals. As in the foregoing embodiment, it may also be an integrally formed piece with three annular parts.

[Easy to pull out structure]

As shown in Figure (2) a, the tilt control rod 46 has a through hole 210; the through hole 210 penetrates the tilt control rod 46. The through hole 210 is made by arranging the aforementioned through hole 55 and the through hole 146 coaxially.

The tilt control rod 46 has a control rod exposure part 212 exposed on the upper side of the valve assembly 38. The through hole 210 is designed in the control rod exposure part 212. The inside of the through hole 210 is hollow and no objects are inserted into the through hole. 210. The through hole 210 is provided for pulling out the valve assembly 38, and the through hole 210 is not used for other purposes except for pulling out the valve assembly 38.

9(a) and 9(b) are cross-sectional views showing the process of pulling out the valve assembly 38. When the valve assembly 38 is replaced, the used valve assembly 38 is taken out of the faucet body 12. In this case, first, remove the lever handle 14 from the tilt lever 46, and secondly, remove the valve fixing member 12c. As a result, It becomes the state shown in FIG. 9(a), and in this state, the valve assembly 38 is accommodated in the accommodation part 13. The valve assembly 38 can be pulled up, and only the exposed part 212 of the control lever holding the tilt control lever 46.

However, it is not easy to pull up, and the sealing part will stick tightly due to long-term use. In the state of FIG. 9(a), adhesion is generated in the lower end sealing member 66. When the valve assembly 38 is pulled up, an upward pulling force F exceeding the adhesion force is required; however, the exposed portion of the tilt lever 46 is thin Also short, the exposed part of the tilt lever 46 is difficult to hold, and therefore, the valve assembly 38 is difficult to pull up.

Furthermore, in addition to the lower end sealing member 66, the valve assembly 38 has an upper end sealing member 40, and the upper end sealing member 40 also has adhesion. Therefore, a greater pull-up force F is required.

In order to solve the difficulty of pulling up, in this embodiment, a through hole 210 is designed. In the through hole 210, a tool or a string can be used to pass through the through hole 210, and the valve assembly 38 "Effect of easy removal" can be easily pulled up. As the tool, for example, a hexagonal wrench can be used.

The cross-sectional shape of the through hole 210 may be a circle or a shape other than a circle. From the viewpoint of ease of pulling up, the maximum cross-sectional length of the cross-section of the through hole 210 is preferably 1 millimeter (mm) or more, more preferably 2 mm or more, and even more preferably 3 mm or more. Considering the size and strength of the tilt lever 46, the maximum cross-sectional length of the cross-section of the through hole 210 is preferably 5 mm or less, more preferably 4.5 mm or less, and even more preferably 4 mm or less. For example, when the cross-sectional shape of the through hole 210 is circular, the aforementioned maximum cross-sectional length means the diameter of the circle; for example, when the cross-sectional shape of the through hole 210 is square, the aforementioned maximum cross-sectional length , Which means the diagonal of the square.

[Left and right click mechanism with high degree of freedom in the faucet structure]

In the foregoing embodiment, the click revolving body 56 rotates "left and right rotation" by the rotation force applied from the tilt control lever 46; the tilt control lever 46 directly abuts the click revolving body 56, and the rotation force is applied by the contact. Therefore, it is not necessary to rotate the click revolving body 56 against the revolving body 44, and because it is not necessary to expose the revolving body 44 to the upper side, the design freedom of the valve assembly 38 is improved. As a result, for example, a sealing structure using the upper sealing member 40 It is possible.

〔Exposed click rotation〕

If the click mechanism is located inside the valve assembly 38, the click sound becomes difficult to hear. In contrast, the click rotation body 56 is exposed in the valve assembly 38, that is, as shown in Figures 2(a) and 2(b) Shows that in valve assembly 38, The click rotation body 56 constituting the click mechanism is exposed, and therefore, the click sound transmitted to the ear becomes louder, and the clarity of left and right clicks improves "click sound amplification effect 1".

The aforementioned sealed structure has high sound insulation. Even if the click mechanism is designed in this closed structure, the click sound is blocked, and the click sound becomes smaller. In the foregoing implementation aspect, on the one hand, a closed structure is adopted, and the click mechanism is exposed. Therefore, the click sound can be made louder "click sound amplification effect 2".

In the foregoing embodiment, not only the rotating body 44 but also the tilt control lever 46 transmits and rotates to the click rotating body 56. Therefore, without exposing the rotating body 44, the click rotating body 56 related to the left and right clicking sound "click sound" can be exposed to the "tilt lever rotation transmission effect".

[The reliability transmitted by the rotation of the two contact parts]

In the foregoing embodiment, the rotation "left-right rotation" of the tilt control rod 46 is transmitted by two contact parts, that is, the tilt control rod 46 has the first contact part 214, which transmits the turning force to the click rotation body 56, The rotation force is transmitted to the second contact portion 216 of the click revolving body 56 at a position different from the first contact portion 214 described above. The first contact portion 214 directly contacts the click revolver 56 and transmits the revolving force to the click revolver 56; the second contact portion 216 directly contacts the click revolver 56 and transmits the revolving force to the click revolver 56.

In the foregoing embodiment, the first contact portion 214 is a side surface 154a of the protruding extension portion 154 "refer to Figures 2(a) and 2(b)". This first contact portion 214 contacts the first The control rod contact surface 180 "refer to FIG. 7" transmits the turning force to the click turning body 56. In the foregoing embodiment, the second contact portion 216, the side surface 150a of the collar portion 150 "refer to Figures 2(a) and 2(b)", this second contact portion 216 contacts the second control The rod contact surface 184 "refer to FIG. 7" transmits the turning force to the click turning body 56. With two contact parts, the turning force is reliably transmitted to the tilt lever 46 and then to the click turning body 56 "Stable turning effect".

Furthermore, this rotation transmission can be achieved in any rotation direction. Referring to Fig. 7, when the left and right rotation of the tilt lever 46 is the first direction, click on the surface of the rotating body 56 that receives the rotating force, which is the first lever contact surface 180a on the right and the second lever contact surface 184b on the left. ; When the left and right rotation of the tilt lever 46 is the second direction, click on the surface of the rotating body 56 that receives the rotating force, which is the first lever contact surface 180b on the left and the second lever contact surface 184a on the right. Since the surfaces receiving the turning force are dispersed on the left and right sides of the tilt lever 46, the turning "left-right dispersion effect" can be transmitted more stably and reliably. In addition, the aforementioned turning in the first direction means either a left turn or a right turn. The aforementioned rotation in the second direction refers to a rotation opposite to the aforementioned first direction.

As described above, when the rotating body 56 is clicked, the rotating force is received at the first control lever contact surface 180 and the second control lever contact surface 184. The action point (active site) of the turning force in the first control lever contact surface 180 is called a first action point; the action point of the turning force on the second control lever contact surface 184 is called a second action point. As mentioned above, these action points are scattered on the left and right sides of the tilt lever 46; furthermore, these action points It can also be dispersed in the peripheral direction, and this dispersion in the peripheral direction contributes to stable and reliable rotation transmission "peripheral direction dispersion effect".

The phase difference between the first operating point and the second operating point in the peripheral direction relative to the rotation center line of the click slewing body 56 is preferably 110 degrees (110 degrees) or more, and 120 degrees or more. It is more ideal, more than 130 degrees is more ideal, and more than 140 degrees is more ideal. The phase difference is below 180 degrees. In the foregoing embodiment, the phase difference between the first operating point and the second operating point varies with the tilt position of the control lever, but the maximum is 151.5 degrees (151.5°).

〔Transmission of rotation of all lever tilt positions〕

As mentioned above, Figure 2(a) shows the water-stop state, and Figure 2(b) shows the water state; in Figure 2(b), the water output is the largest. Figure 2 (a) and Figure 2 (b), respectively, are the limit of the tilt position of the control lever, and the movable range of the tilt position of the control lever is the range from the position of Figure 2 (a) to the position of Figure 2 (b) .

In the tilt position of the control lever in FIG. 2(a), the rotation "left and right rotation" of the tilt control lever 46 is transmitted to the click revolving body 56, and this revolving transmission, as described above, is supported by the two contact portions "first contact portion 214 and The second contact part 216" is reached. In the tilt position of the control lever in Fig. 2(b), the rotation "left and right rotation" of the tilt control lever 46 is also transmitted to the click rotation body 56, and this rotation transmission is also carried out by the two contact parts "first contact part 214 and second contact part". Contact part 216". In all the tilt positions of the control lever, the rotation of the tilt control lever 46 is transmitted to the click rotation body 56 by the two contact parts "first contact part 214 and second contact part 216". Regardless of the tilting position of the control lever, once the tilting control lever 46 is rotated, clicking the rotating body 56 will rotate the "full tilt position effect"; regardless of the tilting position of the control lever, the left and right clicking sound "click" will occur.

Regarding the first contact portion 214, regardless of the tilt position of the control lever, the side surface 154a of the protruding extension portion 154 and the first control lever contact surface 180 can contact regardless of the tilt position of the control lever; therefore, regardless of the control lever Regardless of the tilt position of the lever, the turning force is transmitted from the first contact portion 214 of the tilt control lever 46. Furthermore, regarding the second contact portion 216, the side surface 150a of the collar portion 150 and the second lever contact surface 184 can be in contact regardless of the tilt position of the control lever; therefore, regardless of the tilt position of the control lever, The turning force is all transmitted from the second contact portion 216 of the tilt control lever 46.

In this embodiment, the first contact portion 214 "side surface 154a" and the second contact portion 216 "side surface 150a" of the tilt lever 46 are different surfaces; however, the first contact portion 214 and the second contact portion 216 are also different from each other. Can be in different positions in the same plane.

〔Transmission of rotation in a closed structure〕

As mentioned above, the valve assembly 38 has a closed structure. As shown in Figures 3(b) and 4(b), the rotating body 44 is tied to the lower side of the control rod sealing member. In the valve assembly 38, the rotating body 44 is parallel to Not exposed, the rotating body 44 is located inside the sealed part. As mentioned above, in the present embodiment, the tilt lever 46 transmits the rotation to the click rotation body 56, therefore, there is no need to transmit the rotation to the click rotation body 56 by the rotation body 44, so there is no need to expose the rotation body 44 on the upper side. , Can be easily made into a closed structure "easy effect of closed structure".

〔Prevent click revolver 56 from falling off〕

As mentioned above, the click rotation body 56 is loaded on the small-diameter cylindrical part 120. The click slewing body 56 rotates while being guided by the small-diameter cylindrical portion 120, but only the loading is not fixed; this unfixed state, in addition to the rotation of the click slewing body 56, also makes the slight vibration of the click slewing body 56 easy to occur , This slight vibration increases the sound pressure of the click sound generated by "clicking sound amplification effect 3". However, because it is not fixed, the click revolving body 56 is in a state of being easily removed from the small-diameter cylindrical portion 120 and dropped.

In this embodiment, the click revolving body 56 is effectively prevented from falling off. As shown in FIG. 6, the tilt control lever 46 "control rod cap 46b" has a collar portion 150 and a bottom surface forming portion 152, and at least a part of these parts is located on the click revolver 56 "upward curved surface (upward curved surface). ) 182" on the upper side "refer to Figure 2 (a), Figure 2 (b), Figure 3 (c) and Figure 4 (c)". In all the tilt positions of the control lever, any part of the tilt control lever 46 "control lever cap 46b" is located on the upper side of the click revolving body 56; that is, the tilt control lever 46 "control lever cap 46b" has no matter whether the control lever is tilted Regardless of the position, they are all located in the click holding part 220 on the upper side of the click revolving body 56. In this embodiment, the collar portion 150 and the bottom surface forming portion 152 are click holding portions 220 "refer to Figure 3(c), Figure 4(c) and Figure 6(b)".

The bottom surface forming portion 152 as the click holding portion 220 is positioned on the upper side of the upward curved surface 182. The bottom surface forming portion 152 has a curved surface along the upward curved surface 182 "Refer to Figure 3(c) and Figure 4(c)", The vertical distance of the gap between the bottom surface forming portion 152 and the upward curved surface 182 is constant regardless of the tilt position of the control lever.

There is a "tiny" gap between the click and hold part 220 and the upper surface "upward curved surface 182, etc." of the click revolver 56. Therefore, the click and hold part 220 will not touch the click revolver 56, and the click and hold part 220 will not make the lever Operating force increases. When the click rotation body 56 is displaced upward for some reason, the click rotation body 56 hits the click holding part 220 to prevent the click rotation body 56 from falling off "click rotation body retention effect".

[Prevention of tipping over of tilt lever 46]

When the operating force of the control lever handle 14 is too large, an excessive load may act on the tilt control lever 46 at the limit of the tilt position of the control lever. In this embodiment, a structure corresponding to this situation is designed. As shown in Figures 6(a) and 6(b), the lever cap 46b "tilt lever 46" has a protruding extension portion. 154; As shown in Figure 3 (b), when the tilt position of the lever is in the water stop position, the protruding extension 154 contacts the upper shell 42 "small diameter cylindrical portion 120"; in more detail, the front end of the protruding extension 154 154b is in contact with the upper shell 42 "small diameter cylindrical part 120", and by this contact, the tilt lever 46 is prevented from overturning excessively "overturn prevention effect 1"; the water stop position is the limit of the tilt position of the lever The protruding extension portion 154 is tied to the tipping prevention portion 222 that abuts the upper end housing 42 in the limit of the tilt position of the lever.

The limit of the tilt position of the control lever is the water stop position and the maximum water outlet position. In the water stop position, as described above, the overturning preventing portion 222 contacts the upper housing 42. As shown in FIG. 5, the upper housing 42 has an inner corner portion 42 b formed by the intersection of the upper surface of the sealing support portion 126 and the inner peripheral surface of the small-diameter cylindrical portion 120. The tip "front end 154b" of the tipping prevention portion 222 contacts the inner corner portion 42b; the inner corner portion 42b stably supports the tipping prevention portion 222.

The overturning prevention part 222 acts on the left and right positions of all the levers. As shown in FIG. 5, the inner corner portion 42b extends in a specific range in the circumferential direction; the inner corner portion 42b abuts the overturn prevention portion 222 at the left and right positions of all the levers.

At the maximum water outlet position, the upper housing 42 abuts the tilt control lever 46 "control lever shaft 46a" "refer to FIG. 4(b)". The upper housing 42 has a tipping prevention contact surface 42a that contacts the tilt lever 46 "control lever shaft 46a" at the limit of the tilt position of the control lever, thereby preventing excessive tilting of the control lever 46 Ground tipping "Tipping Prevention Effect 2". The tipping prevention contact surface 42a is oriented "tilt" to make surface contact with the tilt lever 46 at the maximum water outlet position.

The tipping prevention contact surface 42a acts on the left and right positions of all the levers. As shown in FIG. 5, the tipping prevention contact surface 42a extends in a specific range in the peripheral direction; the tipping prevention contact surface 42a contacts the tilt lever 46 "control lever shaft 46a" at the left and right positions of all levers.

〔Prevent the ratchet plate 58 from falling off〕

As mentioned above, the ratchet plate 58 is mounted on the upwardly facing surface 124 of the upper end housing 42 "refer to FIG. 5, FIG. 2(a), and FIG. 2(b)". Because it is only for loading, the ratchet plate 58 may fall off from the valve assembly 38. When the valve assembly 38 is attached to the faucet body 12, the ratchet plate 58 will not fall off the valve assembly 38 because of the valve fixing member 12c; however, only When the valve assembly 38 or the valve fixing member 12c is removed, the falling off of the ratchet plate 58 is still a concern.

In the aforementioned embodiment, the click revolving body 56 has a ratchet plate holding portion 226. In the valve assembly 38, the lower extension 168 doubles as the ratchet plate holding portion 226. The ratchet plate holding portion 226 "lower extension 168" is located on the upper side of the ratchet plate 58. If the ratchet plate 58 is displaced upward, the ratchet plate 58 hits the lower end of the lower extension 168 to prevent the ratchet plate 58 from shifting. The ratchet plate holding part 226 "lower extension part 168" prevents the ratchet plate 58 from falling off "ratchet plate holding effect".

By turning the tilt lever 46 to the left and right, the click revolving body 56 revolves; once the click revolving body 56 rotates, the position in the peripheral direction of the lower extension 168 also moves. Regardless of the peripheral position of the lower extension portion 168, the lower extension portion 168 is located on the upper side of the ratchet plate 58, that is, the ratchet plate holding portion 226 "lower extension portion 168", regardless of the left and right position of the lever, is located on the ratchet The upper side of the plate 58, regardless of the left and right positions of the lever, the ratchet plate 58 is prevented from falling off.
