The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises water tank 1, storage pressure chamber 2, check valve 3, pumping chamber 10, choke valve 4, low pressure exhaust valve 9, heating clamber 7, pressure-relief valve 8, thermostat 5, fuse 6 etc.The water inlet of pumping chamber 10 is connected with water tank 1 bottom by check valve 11, and pumping chamber's 10 delivery ports press chamber 2 water inlets to be connected by check valve 12 and storage; Heating clamber 7 water inlets press chamber 2 delivery ports to be connected by choke valve 4, check valve 3 with storage, and heating clamber 7 delivery ports are connected with pumping chamber's 10 bottom piston, low pressure exhaust valve 9, pressure-relief valve 8 respectively by conduit; Low pressure exhaust valve 9 links to each other with the conduit 13 that extends into water tank 1 top; Pressure-relief valve 8 is in communication with the outside by conduit 15, and whole device forms closed circuit.
As shown in Figure 3, pressure-relief valve 8 is made up of gum cover 24, valve body 21, valve pocket 22 and spring 23.Gum cover 24 is a drum type elastic rubber sleeve that can move between unlatching and closed valve body air inlet position, and spring 23 1 ends link to each other with valve body 21 gas outlets, and the other end links to each other with gum cover 24, makes gum cover 24 be the urgent shape that contacts with valve body 21 air inlets; At this moment, the pressure of the water vapour in the heating clamber 7 can only affact gum cover 24 and 21 very little closed area areas of valve body, so the pressure of heating clamber 7 must very highly could be opened, in case after opening, water vapour pressure in the heating clamber 7 can evenly pass to pressure-relief valve 8 inner whole spaces, make the whole pressurizeds of pressure-relief valve 8 inner surfaces, and spring 23 force variation are little; Therefore, pressure-relief valve 8 needs open under elevated pressures, then still is held open under lower pressure, drops to the setting level up to pressure and just closes, and can make heating clamber 7 and pumping chamber 10 have the sufficient time to discharge more water vapour and reset smoothly like this.
As shown in Figure 4, low pressure exhaust valve 9 is made up of spool 27, valve body 26 and valve pocket 25.Spool 27 is elastic silicone rubber materials, be " soil " type, fixedly be inserted in the valve body 26 by upper and lower spacing interface, when pressure strengthened, spool 27 outwards was out of shape because of pressurized, the conical centre bore of its conical axis and valve body 26 is harmonious, the sealing exhaust outlet, when pressure hour, spool 27 elastic reset on one's own account, gas is discharged from the passage between spool 27 axis and valve body 26 grooves, makes water can enter heating clamber 7 smoothly; A small amount of gas of discharging from low pressure exhaust valve 9 returns water tank 1 through conduit 13, communicates with outside air.
As shown in Figure 5, pumping chamber 10 is made up of cylinder 30, piston 17 and spring 16.Piston is an elastic silicone rubber drum type gum cover, and the edge is " S " type, both conveniently moves back and forth, and avoids the friction of piston 17 and cylinder 30 inwalls, strengthens the sealing effectiveness of cylinder 30 and piston again, has improved the sensitivity and the service life of device; The one side of piston 17 communicates with heating clamber 7, and the periodic pressure of heating clamber 7 changes to be made piston 17 motions and hydraulic pressure is gone into storage pressure chamber 2; Spring 16 1 ends link to each other with cylinder 30 inwalls, and the other end links to each other with piston 17, and piston 17 is resetted, and suck water simultaneously.
As shown in Figure 6, storage presses chamber 2 to be made up of cylinder 31, piston 19 and spring 18.Spring 18 1 ends link to each other with cylinder 31 inwalls, and the other end links to each other with piston 19, are parastate with the entery and delivery port passage of cylinder 31.After water is pressurized chamber 10 and is pressed into storage and presses chamber 2, under spring 18 effects, produce pressure, when heating clamber 7 pressure reduced, the water of storage pressure chamber 2 internal memories just was pressed into heating clamber 7.
The suitable flow of choke valve 4 control, its size and storage press pressure size when pressure and pressure-relief valve 8 are closed in the chamber 2 to determine, generally select the aperture of diameter 1.5~0.8mm for use, but also manual adjustments.
Thermostat 5 can keep the constant operating temperature of heating clamber 7, when temperature in the heating clamber 7 surpasses 150 ℃, thermostat 5 is outage automatically, temperature is lower than 120 ℃ in heating clamber 7, thermostat 5 energising heating automatically, 5 series connection of fuse 6 and thermostat, when device short circuit or heating clamber 7 temperature were too high, fuse 6 can disconnect.
The operating pressure of each parts of the utility model must be set in suitable level just can make it operate as normal, and the pressure size is set as follows:
Heating clamber 7 internal pressures when pressure-relief valve 8 is opened>chamber 2 internal pressures>heating clamber 7 internal pressures when pressure-relief valve 8 has just cut out>outlet pipe 13 internal pressures>heating clamber 7 internal pressures when low pressure exhaust valve 9 cuts out>base pressure>external air pressure when water tank 1 is filled water was pressed in pressure>storage when heating clamber 7 sealed.
Pressure generally is set at 1.5~3bar during heating clamber 7 sealings,
Base pressure was generally 0.02~0.03bar when water tank 1 was filled water.
As shown in Figure 7, outlet pipe 13 internal pressures are that recurrent pulses change, and reach as high as 2~3bar.
When the utility model in when heating energising not, low pressure exhaust valve 9 is in opening, the water in the water tank 1 can flow directly in the heating clamber 7.When in heating, water vapor in the heating clamber 7 is expanded, produce pressure, low pressure exhaust valve 9 cuts out automatically because of pressurized, the water vapour expanded by heating, piston in the pumping chamber 10 is outwards moved, the space of pumping chamber's 10 other sides dwindles, and the water that is deposited in here is compressed through check valve inflow storage pressure chambers 2 12, and the water in the heating clamber 7 are further vaporized, the bulbs of pressure further strengthen, when reaching the pressure of setting, pressure-relief valve 8 can be opened automatically, and the pressure in the pumping chamber 10 descends, high-temperature high-pressure steam is flowed out by pressure-relief valve, flows out through conduit 13.At this moment heating clamber 7 internal pressures descend, the piston resilience under spring action in the pumping chamber 10, and pumping chamber's 10 other sides are because of space enlargement, and pressure is lower than external air pressure, and the water in the water tank 1 enters this space through check valve 11 and fills, and finishes water absorption course.Simultaneously, storage presses the water in the chamber 2 to flow to heating clamber 7 through check valve 3 and choke valve 4 under spring 18 pressure effects, and heating clamber 7 interior temperature are descended, pressure further descends, when pressure was reduced to the setting level, pressure-relief valve 8 can seal under the thrust of spring 23 automatically, finishes this cyclic process.Because heating clamber 7 continues heating, make heating clamber 7 internal pressures begin again to strengthen, when pressure surpasses storage pressure chamber 2 internal pressures, going into water one-way valve 3 closes automatically, piston in the pumping chamber 10 outwards moves, the water of compression piston opposite side enters storage through check valve 12 and presses chamber 2, begins next cyclic process so again; This cyclic process can continue until that system cuts off the water supply or cut off the power supply.The high-temperature high-pressure steam that flows out through conduit 13 mixes mutually with coffee powder 29, promptly forms coffee beverage after filter screen 28 filters.
