Background technology:
The closet that before me, patent application is introduced, cylinder barrel (5) inwall being connected with closet piston (1), there are piston (22) and piston (6), when between piston (6) and piston (22), hydraulic pressure increases, when cylinder barrel moves down, in piston (22) and cylinder barrel () inwall Relative friction motor process, hole for water spraying (23) in inner wall of cylinder through piston (22) if time piston (22) with inner wall of cylinder contact portion be elastic material, hole for water spraying (23) can have certain abrasion to piston, hole for water spraying can be by the resistance of piston, when between piston (6) and piston (22), hydraulic pressure disappears, cylinder barrel can upwards be replied, hole for water spraying (23) is when piston (22), meeting repeated wear and the problem of resistance again.
The closet that before me, the above patent of application is introduced simultaneously, open at closestool port piston, in the of short duration time of toilet flushing, the unavoidable stimulation temperature air arrival closestool port of closet depths pipeline that also has is with the external space, so the present invention adds minimizing in pan pipeline, discharges, blocks the device of abnormal smells from the patient.
Detailed description of the invention:
The closet cylinder barrel of the present invention, the interlayer (9) being made up of internal layer (10) and outer layer (11), interlayer top and bottom between internal layer (10) and outer layer (11) are cylinder barrel top and bottom respectively, and interlayer top and bottom seal isolation with extraneous completely.Cylinder barrel top is connected with piston (1), inner wall of cylinder has piston (6) fixed thereto, piston (6) is placed on the outer central siphon (19) of interlayer, inner wall of cylinder also have fixing with outer central siphon (19), can the piston (22) of relative motion upper and lower with inner wall of cylinder.
When piston seals closestool port, only between piston (22) and piston (6), the cylinder barrel internal layer inwall of scope has inlet opening (12), other scope internal layer inwall does not has inlet opening, at cylinder barrel outer layer, it is provided with some hole for water sprayings from top to bottom, wherein have and can make current that duct bottom defecation rushes at the hole for water spraying (13) rotating wheel direction, the inwall of the water that hole for water spraying (13) sprays equally flushing pipe above-below direction.
Having rotatable pan pipeline air exclusion to take turns (65) in pan pipeline, isolation wheel place pipe section has one section of circular arc pan pipeline, wheel subcenter to have axle (63), and axle two ends are through on pipeline.Rotate the inwall of wheel outer ring operating track (62) and closet arc shape pipeline part range, it it is the least standard gap, gap, circular arc inwall length (L1) of this scope pipeline, more than the arc length (L2) rotated between wheel two adjacent protrusion teeth in the rotary motion trace of place, ensure no matter to rotate wheel in any angle position, rotate the air of wheel place pipe ends, through rotating the gap between wheel and closet arc shape pipeline, the standard gap of the minimum that teeth are formed will be protruded with pipeline through twice rotation wheel, so that rotating wheel to reach preferably to completely cut off the effect of air.Wheel fast rotation is rotated during in order to make chamber pot flushing water, closet passage is provided with hole for water spraying (14), hole for water spraying (14) place pipeline (12) is the extensional pipeline of pipeline (12), during chamber pot flushing water, the current that hole for water spraying (14) sprays are sprayed on rotation wheel, add rotary power for rotating wheel.
At pan pipeline upper end position, there is a closet vent passages (70) being in communication with the outside, passage is away from the port height height as far as possible of pan pipeline one end, so that port air pressure is less than pan pipeline inner air pressure, so that after vent passages is opened, air in pan pipeline can continue to flow to outside vent passages by vent passages, and vent passages character, to act like boiler chimney the same.Pressure valve (71) is had on pipeline, pressure valve is connected with a press water pipeline (12), this pipeline is the extensional pipeline of closet water pipeline (12), after pressure valve is opened, in pan pipeline, the air at vent passages mouth is outwards circulated by ventilation shaft, thus when chamber pot flushing water, in stopping pan pipeline, air arrives the outer space, place of closestool port through closestool port.
Pan pipeline plugging device, including pan pipeline, seal up the piston (56) of pipeline, piston is connected with pull bar (55), stopper (53) fixed thereto is had on pull bar (55), spring (58) is had on stopper, it is enclosed within pull bar, the circle protruding (59) that spring top is connected with interlayer cylinder barrel compresses, and the potential energy of spring makes piston (56) tightly block the pan pipeline air circulation of pipeline piston (56) two ends.
Closet plugging device also includes water source and the pipeline (12) with certain pressure, one Sealed sandwich cylinder barrel (51), the outlet (52) of inner wall of cylinder, fixing stopper (54) below inwall outlet, described interlayer cylinder barrel (51) outer wall is fixed on pan pipeline upper end, cylinder barrel interlayer is connected with closet water pipeline (12), pull bar (55) top passes stopper (54) center, and the pull bar through stopper (54) can move up and down, fixing stopper (53) on pull bar can move up and down at cylinder barrel (51) inwall with pull bar, pull bar moves up and down, spring (58) compresses therewith or replys.
While closet starts bath, the pressure valve (71) that the hole for water spraying (14) of the extensional pipeline (12) of pipeline (12) starts to rotation wheel water spray is connected with pipeline (12) is opened by hydraulic pressure, air in pan pipeline can pass through vent passages (70) and start to circulate outward to passage (70), thus substantially stopped pan pipeline air and be passed to closestool port free surrounding space.The interlayer cylinder barrel (51) being connected with pipeline (12) starts water inlet, increase along with water inlet and water inlet has certain pressure, stopper (53) is by water pressure upwards, spring (58) is compressed, pull bar (55) and piston (56) move up, and pan pipeline closure piston (56) is opened.
Enter the current of closet cylinder barrel interlayer (9), sprayed by hole for water spraying (13), spray to pan pipeline above-below direction, bottom interior wall, defecation is rushed to rotating at the wheel (65) gap with closet arc shape pipeline by water rapidly, due to defecation and the common pressure of bath, and the impulsive force that the water spray of simultaneously hole for water spraying (14) is to rotating wheel, rotation wheel rotates, defecation and bath rotate arrival pipeline piston (56) lower section pipeline with rotating wheel.
After toilet stool washing terminates, closestool port piston (1) seals up closestool port, and the water pressure of pipeline (12) disappears, and pressure valve (71) returns to closed mode, pull bar and piston (56), by spring-return power, are moved downward to block pan pipeline.
