Two intake antrums 31,32 of discharge mechanism 3 cooperate with inner core tube 2 forward end seal, and wherein intake antrum 31 communicates with above-mentioned diversion channel 25, and it is soaked to give vent to anger; Another intake antrum 32 communicates with above-mentioned diversion channel 26, goes out gondola water faucet water, is distributed with bubble water hole 331 and gondola water faucet water hole 332 on the water outlet panel 33 of discharge mechanism 3.
Flow control valve 4 comprises a central bolt 41, a back-moving spring 42, a valve pocket 43 and a button 44; Central bolt 41 holds back-moving spring 42 and is matched with in the control valve containing cavity 23 by the activity that valve pocket 43 seals, and is formed with the flange 411 of shutoff small-large flow delivery port 233,232 on the central bolt 41; Central bolt 41 lower ends are to convexedly stretch in outside the control valve containing cavity 23 and pass pressing plate 6 one ends to be connected with button 44, and this end of pressing plate 6 and central bolt 41 lower ends are by touching.
Transfer valve 5 comprises a central bolt 51 and a valve pocket 52, central bolt 51 is matched with in the transfer valve containing cavity 22 by the activity of valve pocket 52 sealings, also be formed with the flange 511 of shutoff two delivery ports 222,223 on it, the lower end side of central bolt 51 forms fluting 512, this fluting 512 convexedly stretches in outside the transfer valve containing cavity 22, the other end of supply plate 6 is planted and is cooperated, and is provided with a door 7 in addition below the other end of pressing plate 6.Door 7 and button 44 just are positioned at mating holes 12 places of water outlet body 1.
The middle part of pressing plate 6 is to be articulated between the control valve containing cavity 23 and transfer valve containing cavity 22 of inner core tube 2 belows, forms a movable seesaw.
After the combination, at the discharging device of water flowing state not, back-moving spring 42 in its flow control valve 4 is in free stretched condition, the central bolt 41 of this moment is held by back-moving spring 42, button 44 relative water outlet bodies 1 protrude out outside, flange 411 on the central bolt 41 is that the big flow delivery port 233 of control valve containing cavity 23 is sealed, water inlet 231 is in communicating state with low discharge delivery port 232 simultaneously, the effect of compression plate 6, this moment, the other end of pressing plate 6 was to be resisted against on the lower surface of fluting 512, the central bolt 51 of transfer valve 5 is to be in relative upper position, and with upper water-out mouth 222 shutoff of transfer valve containing cavity 22, its water inlet 221 communicates with its lower outlet 223.Cooperate shown in Figure 2, this moment is if fetch boiling water source switch, the current of discharging device are to enter the diversion channel 26 of inner core tube 2 and enter in the water chamber 32 of discharge mechanism 3, when current flow in three waterways 24 by the low discharge delivery port 232 of control valve containing cavity 23, current are from going into water channel 241 when water outlet 243 flows out, a part of current can flow back into control valve containing cavity 23 from being lowered to water channel 242, has a back pressure with flange 411 lower surfaces to central bolt 41, go out gondola water faucet water this moment, because current are the restrictions that are subjected to low discharge delivery port 232, the gondola water faucet water of this moment is in the water saving state.
Cooperate shown in Figure 3, when needs carry out the water outlet switching of big flow, push the button 44 of flow control valve 4 this moment, because in the low discharge process of above-mentioned discharging device, flange 411 lower surfaces of central bolt 41 have a back pressure, this moment is when pushing button 44, with back pressure be that same direction is to central bolt 41 application of forces, under the power-assisted of back pressure, can easily central bolt 41 be promoted, simultaneously compression reseting spring 42; Central bolt 41 is just opened big flow delivery port 233 when moving up, the current that enter control valve containing cavity 23 can have the hydraulic pressure effect by while centering heart bolt 41 flanges 411 lower surfaces, when compression puts in place, pine oil button 44, then central bolt 41 can not resetted by the hydraulic pressure effect; The low discharge delivery port 232 of control valve containing cavity 23 is sealed, the current of inner core tube 2 are lowered to water channel 242 and flow out from water outlet 243 from three waterways 24 that enter inner core tube 2 after big flow delivery port 233 flows out by the water inlet 231 of control valve containing cavity 23, in addition some current can through on go into low discharge delivery port 232 places that water channel 241 flows back into control valve containing cavity 23, with the back pressure of being exerted pressure in the upper surface of central bolt 41 flanges 411, the direction of this back pressure is consistent with the elastic force direction of back-moving spring 42, and the elastic force of the back pressure of this backflow and back-moving spring 52 forms stack.Meanwhile, the effect of compression plate 6, the central bolt 51 of transfer valve 5 is to be in relative lower position, lower outlet 223 shutoff with transfer valve containing cavity 22, its water inlet 221 communicates with its upper water-out mouth 222, and the current of this moment are to enter the diversion channel 25 of inner core tube 2 and enter in the water chamber 31 of discharge mechanism 3 realization bubble water, because current are to be subjected to flow to from big flow delivery port 233, the bubble water of this moment is in big flow status.
Cooperate shown in Figure 4, discharging device in the process of big flow when low discharge switches, push door 7, the effect of compression plate 6 movable seesaws, this moment, one end of pressing plate 6 was that the central bolt 41 that drives flow control valve 4 moves down, owing to go into the current that water channel 241 is back to low discharge delivery port 232 places of control valve containing cavity 23 on three waterways 24, has a back pressure with upper surface to central bolt 41 flanges 411, the direction of this back pressure is consistent with the elastic force direction of back-moving spring 42, the two forms stack, therefore central bolt 41 can overcome the suffered hydraulic pressure in flange 411 lower surfaces, being drawn back into big flow delivery port 233 smoothly goes into and it is sealed, water inlet 231 is in communicating state with low discharge delivery port 232 simultaneously, and the discharge mechanism 3 of this moment is low discharge water outlets; Because transfer valve 5 memoryless functions, the central bolt 51 of transfer valve 5 remains lower outlet 223 shutoff with transfer valve containing cavity 22 at this moment, the current of this moment are to enter the diversion channel 25 of inner core tube 2 and enter in the water chamber 31 of discharge mechanism 3, realize bubble water, because current are to be subjected to flow to from low discharge delivery port 232, the bubble water of this moment is in the low discharge state.
To sum up, the utility model is owing to control valve containing cavity 23 upper and lowers in the inner core tube 2 of intaking offer a low discharge delivery port 232 and a big flow delivery port 233, central bolt 41 by control valve 4 switches shutoff, and be provided with one or three waterways 24 in the inner core tube 2 and in control valve containing cavity 23 the place aheads, two of three waterways 24 are gone into water channel 241,242 and are communicated with above-mentioned low discharge delivery port 232 and big flow delivery port 233 respectively, and water outlet communicates with discharge mechanism; Two of this three waterway 24 is gone into water channel 241,242 when the difference water flowing, one of them goes into water channel can reflux a part of current to central bolt 41 generation back pressures, thereby make control valve 4 when switching, be subjected to the power-assisted of back pressure to have the labour-saving of switching effect, it is more convenient and easy to make discharging device switch in exiting water process; The control valve 5 of two series connection, flow control valve 4 are controlled with the interlock of pressing plate 6 formation activity seesaws simultaneously, realize three kinds of state sprays of low discharge gondola water faucet water, low discharge bubble water and big flow bubble water.
