This water unit 200, its sealing is fixed under the overcoat 120, make it and cylinder body 130 seal affixed, and between water unit 200 and cylinder body 130, be formed with a middle chamber 210 that is communicated with waterway 110, wherein, this water unit 200 has three water outlet groups, is respectively main water outlet group 220, the first auxiliary waterexit group 230, the second auxiliary waterexit group 240, described main water outlet group 220 permanent logical middle chambers 210.
This main water outlet group 220, it has the main water-saving piece 224 that the main inlet opening 221 that can connect middle chamber 210, a plurality of main apopore 222, a main water chamber 223 and that is communicated with main inlet opening 221 and a plurality of main apopores 222 are located at main inlet opening 221.This first auxiliary waterexit group 230, it has the first secondary water-saving piece-234 that first water chamber 233 and that the first secondary inlet opening 231 that can connect middle chamber 210, a plurality of first auxiliary waterexit hole 232, one be communicated with the first secondary inlet opening 231 and a plurality of first auxiliary waterexit holes 232 is located at the first secondary inlet opening 231.This second auxiliary waterexit group 240, it has the second secondary water-saving piece-244 that second water chamber 243 and that the second secondary inlet opening 241 that can connect middle chamber 210, a plurality of second auxiliary waterexit hole 242, one be communicated with the second secondary inlet opening 241 and a plurality of second auxiliary waterexit holes 242 is located at the second secondary inlet opening 241.This first secondary inlet opening 231 and the second secondary inlet opening 241 are symmetricly set on about the main inlet opening 221.The first auxiliary waterexit hole 232 of this first auxiliary waterexit group 230 is for being circular layout and surrounding the apopore 222 of described main water outlet group 220; The second auxiliary waterexit hole 242 of the second auxiliary waterexit group 240 is for being circular layout and surrounding the first auxiliary waterexit hole 232 of the described first auxiliary waterexit group 230.
Two active units are defined as first and second active unit 310,320 respectively, and they are corresponding one by one adaptive with first and second auxiliary waterexit group 230,240.
This first active unit 310, it has:
Elastomer, in this embodiment, this elastomer is a spring, i.e. first spring 313, it is installed within first through hole of first fitting recess 311, the socket first reference column A, and contact is between the nut C and first sealing unit 312, with outside contact first sealing unit 312, so that first sealing unit, 312 contacts are gone out first fitting recess, 311 under sheds.
This second active unit 320, it has:
Second fitting recess 321, it is opened in the fixed cell 100, is downward opening second through hole, and other sets nut D dense block and is connected on opening on second through hole;
Elastomer, in this embodiment, this elastomer is a spring, i.e. second spring 323, it is installed within second through hole of second fitting recess 321, the socket second reference column B, and contact is between the nut D and second sealing unit 322, with outside contact second sealing unit 322, so that second sealing unit, 322 contacts are gone out second fitting recess, 321 under sheds.
The spring ratio of described first and second spring 313,323 does not wait, and regulates to realize multistage shower area.Perhaps, adjusting nut C D so that the pretightning force of first and second spring 313,323 do not wait, regulate to realize multistage shower area.
In the preferred embodiment of the present invention, a kind of shower area can be as follows with the method for yielding water of the gondola water faucet of hydraulic pressure size variation:
Step 10, the input variation in water pressure;
Step 20, select to carry out according to variation in water pressure:
Step 21, when hydraulic pressure to the active force of sealing unit during greater than elastomer elastic force, the sealing unit is away from the inlet opening of this water outlet group, this inlet opening is connected, those apopore water outlets of this water outlet group can increase the water-outlet area of whole gondola water faucet;
Step 22, when hydraulic pressure to the active force of sealing unit during less than elastomer elastic force, the sealing unit near and the inlet opening of this water outlet group of contact, this inlet opening sealing, those not water outlets of apopore of this water outlet group can reduce the water-outlet area of whole gondola water faucet.
For example, in the tap opening procedure, this method comprises the steps:
In conjunction with Fig. 2, shown in Figure 3, at first open the inlet valve on the waterway 110 or the tap of external water pipe, make the current waterway 110 of flowing through, this moment, water flow pressure was all less than first, two active units 310,320 interior first, two springs 313,323 elastic force, this is first years old, two sealing units 312,322 is outer sliding to seal first, second mate inlet opening 231,241, because middle chamber 210 permanent logical described main water outlet groups 220, so current are by main inlet opening 221, enter main water chamber 223, flow out from main apopore 222, and first, two auxiliary waterexit groups 230,240 all not water outlets, the water-outlet area of gondola water faucet are minimum;
In conjunction with Fig. 4, shown in Figure 5, increase along with water flow pressure, this moment, hydraulic pressure was greater than the elastic force of first springs 313 in first active unit 310 elastic force of second springs 323 in second active unit 320 (still less than), the sealing unit 312 of this first active unit 310 contracts with the conducting first secondary inlet opening 231 under the elastic force effect, current are through the water chamber 233 of the first auxiliary waterexit group 230, from around flowing out the first auxiliary waterexit hole 232 of main apopore 222, so the main water outlet group of gondola water faucet and the first auxiliary waterexit hole water outlet, the water-outlet area of gondola water faucet also increase thereupon;
In conjunction with Fig. 6, shown in Figure 7, further increase along with water flow pressure, this moment, hydraulic pressure was all greater than first, two active units 310,320 interior first, two springs 313,323 elastic force, the water chamber 223 of the not only main water outlet group 220 and the first auxiliary waterexit group 230,233 conductings, and this moment, the sealing unit 322 of the second auxiliary waterexit group 240 contracted with the conducting second secondary inlet opening 241 under the elastic force effect, thereby make current simultaneously from main water hole 222, around first of main apopore 222, second mate's apopore 232, flow out in 242, the water-outlet area of gondola water faucet increases thereupon, reaches the maximum water-outlet area in this preferred embodiment;
In like manner, if the inlet valve on the slow closed waterway 110 just can be regulated the pressure size of current, thereby correspondingly reduce the water-outlet area of gondola water faucet.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process according to this, i.e. the equivalence of doing according to claim of the present invention and description changes and modification, all should still belong in the scope that the present invention contains.
