The effect of the return spring 47 of pressurized always on each described chain bar T40a, described chain bar S40b, the described chain bar J40c is described now.

Described chain bar T40a, described chain bar S40b, described chain bar J40c are subjected to an anti-snap-in force of return spring 47, for example, a reverse snap-in force of return spring 47 is 1N according to appointment, and described guide rod holder 60 is suffered is about half power of 1N stress, is about 0.5N.And, the stress of half (1.5N) of three snap-in force sums (about 3N) of described spring 47 is arranged in the described guide rod holder 60.

Described chain bar T40a, described chain bar S40b, described chain bar J40c is corresponding, as cam (cam T33, cam S34, cam J35) rotates, the protuberance of cam and chain bar (the chain bar T40a corresponding with cam T33, with the corresponding chain bar of cam S34 S40b, with the corresponding chain bar of cam J35 J40c) protuberance when not touching, guarantee valve body T45a, valve body S45b, valve body J45c can be when low hydraulic pressure (as 0.05～0.10Mpa) close really under can snap-in force effect at 0.5N with valve body T45a over against valve seat T13a, with valve body S45b over against valve seat S14a, with valve body J45C over against valve seat J15a prevent that former water from flowing into the circulation pipeline from the gap of valve body and valve seat.

0025

Now we suppose the protuberance of cam T33, the situation during with 42 pairs of tops of the protuberance of the corresponding connecting rod T40a of cam T33.That is to say that the protuberance discord of cam S34 and the protuberance of the corresponding chain bar of cam S34 S40b are to the top, and the protuberance of the protuberance of cam J35 and the corresponding chain bar of cam J35 J40c is the situation to pushing up not.30 of the camshafts of this moment are subjected to making the upwards stress (stress that chain bar 40a is subjected to from described return spring 47) of action of chain bar T40a, the 0.5N. that only has an appointment (not being subjected to any stress from described chain bar S40b, described chain bar J40c).

So, when described switching pull bar 50 being given as security downwards with finger, described driving gear 20 turns an angle to a direction, with the described follower gear 39 of described driving gear 20 interlocks also to the other direction rotating certain angle, described camshaft 30 is rotating certain angle also, while the protuberance of cam T33, touch chain bar T40a with the protuberance of the corresponding chain bar of cam T33 T40a.If the protuberance of cam S34 and when touching with the protuberance of the corresponding chain bar of cam S34 S40b, chain bar S40b is pushed up up.

Illustrate from the mechanics angle, originally with certain proportion camshaft 30 is rotated by the power of described switching pull bar 50 downwards with finger.When chain bar 40a moved downward, the stress that applies on the chain bar T40a (about 0.5N) also can be coupled with, and cam T33 (camshaft 30) is rotated.And the stress that makes rotation that this is coupled with moves upward the corresponding chain bar of cam S34 S40b.Also say so,, press the power of described switching pull bar 50 downwards,, just be equivalent to the power that allows camshaft 30 under no load condition, rotate because do not need power (about 0.5N) that the chain bar is moved upward with finger from this principle.The effect of Here it is return spring 47.

By the effect of described return spring 47, compared with the past, only need on the switching pull bar 50 that these three kinds of water exit modes of direct former water water outlet/spray water water outlet/water purification water outlet are switched, apply little operating physical force and just can simply easily and positively switch.
