The spring cleansing pin (7) and piston (9) are integrated component, mutual cooperation regulation and control delay time, the bullet
Spring cleansing pin (7) is the piston in the inner hole that a cleansing pin straight cutting plunger booster hole (8) vertically downward is inwardly turned round on spring top
(9) it moving up and down primary, cleansing pin is inserted through sundries or scale in a plunger booster hole (8) automatically in plunger booster hole (8),
The wire diameter of spring cleansing pin (7) is matched with the aperture of plunger booster hole (8), and the wire diameter of spring cleansing pin (7) is small, piston
The aperture of pressurized hole (8) is big, and the circumferential edge gap between spring cleansing pin (7) and plunger booster hole (8) is big, pressurized hole area of passage
Greatly, to water storage cavity (26) pumping rate at the top of piston (9) with regard to fast, delay time is on the contrary then grow with regard to short, on the piston (9)
Portion's outer circle circumference sets a groove, and the piston cup (21) of a bowl-shape shape is set in groove, and piston (9) the bottom cylindrical circumference sets one
Groove, groove outer circle set the piston valve flap with conical (22) of an inner card cage, and the conical surface of piston valve flap with conical (22) longitudinally goes out with cylinder barrel
The apopore cambered surface sealing surface (10) in water hole (27) is adjacent to sealing, and piston (9) centre bit installs a piston up and down
Relief hole (20), the eccentric position of piston (9) top end face sets a plunger booster hole (8) penetrated through vertically downward, by cylinder barrel
The water inlet of inlet opening (13) fills the water pressurization, the piston to the water storage cavity (26) at the top of piston (9) by plunger booster hole (8)
(9) top end face maximum outer circle top sets a spring cleansing pin locating groove (29), prevents spring cleansing pin (7) displacement or de- hole.
The top inner hole of water outlet sleeve (12) sets the lower end outer circle of step and cylinder barrel top O-ring seals (24) in one
Step is engaged, and water outlet sleeve (12) the top circumference is equipped with water outlet sleeve apopore (18), the water outlet sleeve with respect to diameter direction
Cylinder apopore (18) and cylinder barrel transverse direction exhalant canal (11) penetrate through, the inner wall of water outlet sleeve (12) lower part inner hole and cylinder barrel bottom
Portion's O-ring seals (23) mutually seal, and set a plain cushion and valve below the maximum outer circle step of water outlet sleeve (12) top
Mounting surface sealing.
The upper end outer circle of the magnet ring push rod (2) is equipped with external screw thread and connect with button (1) inner hole internal screw thread, and the magnet ring pushes away
A step is set in the lower end maximum inner hole of bar (2) and magnet ring (3) match, and magnet ring push rod (2) inner hole top interlayer sets one and inserts
The opening of screwdriver.
Magnetic column is equipped in the inner hole of bar magnet (14) upper end, bar magnet (14) bottom minimum outer diameter outer circle circumference sets one
Groove, groove outer circle set the relief hole plug (19) of an inner card cage, the bottom face and piston relief hole of relief hole plug (19)
(20) top end face is adjacent to sealing.
Bar magnet sleeve (16) the lower section maximum outer circle is equipped with the internal screw thread in external screw thread and cylinder barrel (17) top inner hole and connects
It connects, bar magnet sleeve (16) lower end maximum outer circle external screw thread bottom is equipped with a circle groove, sets a bar magnet sleeve bottom O in groove
Shape sealing ring (25) and cylinder barrel (17) top maximum inner hole seal, and the minimum inner hole wall circumference of the bar magnet sleeve (16) is equipped with pressure release
Groove (30) drains convenient for pressure release, reduces resistance when bar magnet (14) uplink, the minimum inner hole top end face of the bar magnet sleeve (16)
If a damping and silencing pads (28), top end face collides bar magnet sleeve (16) inner hole when being effectively prevented and reducing bar magnet (14) uplink
Impact noise when top end face.
Open theory of the invention is as follows: promotion magnet ring push rod (2) downlink when push button (1), under magnet ring push rod (2)
Push magnet ring (3) close to bar magnet (14) when row, bar magnet (14) is picked up uplink under the action of magnet ring (3) attraction, makes its magnetic
The relief hole plug (19) of stick (14) bottom end is detached from piston relief hole (20) end sealing mouth, and the pressure water of water storage cavity (26) is from work
Relief hole (20) are filled in cylinder barrel longitudinal direction apopore (27) and cylinder barrel transverse direction exhalant canal (11) pressure release, are lived while pressure release moment
The reduction of water storage cavity (26) pressure and piston (9) bottom intake pressure one apparent pressure difference of formation at the top of (9) are filled in, in influent pressure
Piston cup (21), which expands outwardly, under the action of power is close to the inner wall of cylinder barrel (17) and pushes piston (9) uplink, when piston (9) uplink
Piston valve flap with conical (22) are driven to be detached from the apopore cambered surface sealing surface (10) of cylinder barrel longitudinal direction apopore (27), i.e. valve opening,
The water inlet of two semicircle cylinder barrel water inlets (13) is detached from cylinder by piston valve flap with conical (22) from the inner hole of cylinder barrel (17) bottom
The circumferential clearance of the longitudinal apopore (27) of cylinder is flowed out to cylinder barrel transverse direction exhalant canal (11).
The principle that the present invention closes is as follows: when release button (1), magnet ring push rod (2) is in magnet ring push rod reset spring
(15) elastic force pushes lower magnet ring push rod (2) uplink, drives magnet ring (3) uplink reset to be simultaneously detached from bar magnet (14), magnetic after disengaging
Repulsive force is generated between ring (3) and bar magnet (14), bar magnet (14) downlink is pushed under the action of repulsive force, forces lower end relief hole
Plug (19) blocks the piston relief hole (20) at piston (9) top center, until making to push up from plunger booster hole (8) to piston (9)
The water of portion's water storage cavity (26) pressurization is nowhere drained, and pressure, which is gradually increased, forms pressure difference with piston (9) bottom, is pushed up in piston (9)
The process that portion's water storage cavity (26) pressure is gradually pressurized, force piston (9) gradually come downwards to the conical surface of piston flap (22) lower part with
The apopore cambered surface sealing surface (10) of cylinder barrel longitudinal direction apopore (27) end face is adjacent to closing, i.e. valve is closed, storage at the top of piston (9)
The time speed of the process and piston (9) that water cavity (26) is gradually pressurized gradually downlink is thick by the wire diameter of spring cleansing pin (7)
Set by the circumference overcurrent side gap carefully to match with plunger booster hole (8) pore size.
The foregoing is merely a kind of embodiment of the invention, the protection scope being not intended to limit the invention；Of the invention
