Abstract

The present invention belongs to a flushing device for toilet cistern, and is characterized by that an overflow is opened on the upper portion of the thin-wall cylinder, and a rubber sealing ring is stuck to the edge of its lower hole, and two positioning pieces with guide hole are symmetrically projected on its external surface, and its water outlet has a horizontal upper head face and is equipped with a metal guide bar, automatic hook, ball float and switch. When using the water quantity for flushing can be controlled by means of said switch, and the flushing also can be automatically cut off, and its operation is simple and reliable.

Description

The high and low water tank sanitary equipment of garden tube

The invention belongs to the sanitary apparatus flushing device of urinating and defecating.

The manual high and low water tank sanitary equipment of closet are to have lifted rubber water shutoff plug or lifted dish with handle, snapper and pull bar (rope) switch at present, open delivery port or form siphon flushing closet.Usually, non-hydrocone type sanitary equipment are because rubber water shutoff plug easily misplaces when falling sealing, and it is stressed different to cause sealing place each point rigidity not cause in the lump, causes poorly sealed formation to be leaked.And the pull-rod operator of the complex structure of hydrocone type sanitary equipment, particularly cistern sanitary ware need use than the bigger power of non-hydrocone type sanitary equipment switch, is not suitable for children and the old,weak,sick and disabled person use, thereby has restricted the application of hydrocone type sanitary equipment.

The objective of the invention is in order to overcome the above-mentioned shortcoming that manual high and low water tank sanitary equipment exist, provide a kind of water-tight, low noise, easy and simple to handle laborsaving, washing water quantity can arbitrarily be controlled and easy to maintenance, can with supporting manual water tank sanitary equipment of the high and low water tank of Universal excrement unit now.

Main points of the present invention are to establish through hole in two horizontal plane places up and down at plastics system thin-walled garden tube; At upper end open center system aperture and the external chain (rope) that lifts, the edge is established water inlet and is in charge of jack; The embedding rubber seal is glued by lower ending opening edge; The lower external face symmetry is flatly chosen the spacer in two tape guide holes.Be sleeved on the delivery port top that has the horizontal upper end face, has two vertical and symmetrical metal guide pegs then vertically; Again near on the metal guide peg of ball float position, automatic hook of being furnished with spring of suit.And in water tank, pack into into water float valve and hand switch.Constitute the complete high and low water tank sanitary equipment of manual garden tube of a cover.

Accompanying drawing 1 is the present invention, and (with the low level cistern is example to the cross-sectional view of the high and low water tank sanitary equipment of garden tube, and the model of high level cistern water intaking valve and hand switch is different with the position, and principle is identical.Accompanying drawing 2 also together).

Accompanying drawing 2 is the present invention, the plane structure schematic diagram of the high and low water tank sanitary equipment of garden tube.

Content of the present invention can be divided into two parts:

One, flushing process

When pull with hand, when pressing or pulling (high level cistern is downward Drawing switch rope) hand switch 1, lifting chain bar 2 upwards rotates, and garden tube 4 is pulled upwardly by the chain (rope) 3 of lifting that is installed in its end, garden tube 4 slides vertically upward at the position-limiting action lower edge of spacer 5 guide peg 6, sealing seal break-off, the water storage in the water tank 7 flow to delivery port 8 flushing closets.

When spacer 5 in upwards sliding during collision automatic hook 9, promptly fastened and stop to slide (see in the accompanying drawing 1 shown in the dotted line) by automatic hook 9.

If at ordinary times automatic hook 9 tops are become the horizon bar 10 of an angle of 90 degrees to depress and fix with the hook body, then automatic hook 9 only plays upwards slip of restriction garden tube 4; In flushing process, along with the disappearance that acts on manpower on the hand switch 1, garden tube 4 promptly vertically glides at the effect lower edge guide peg 6 of himself gravity, with delivery port 8 sealings, finishes flushing by the rubber seal 11 of its lower end.This just is equivalent at random to control with hand switch 1 water yield of flushing closet, takes 5 seconds as once water storage in the low level cistern 7 all having been put.

Two, water storage process

In flushing process, along with drawdown in the water tank 7, ball float 12 also descends thereupon, and float valve 13 is opened water inlet; When floating ball lever 14 when automatic hook horizon bar 10 is depressed in self and ball float 12 actions of gravity, automatic hook 9 promptly breaks away from spacer 5, garden tube 4 is sealed delivery port 8 by the rubber seal 11 of its lower end in guide peg 6 vertical drops of the effect lower edge of self gravitation simultaneously, and flushing process finishes.Along with water level in the water tank 7 rises, the pressure that acts on garden tube 4 bottom water increases gradually, closes (seeing accompanying drawing 1 solid line part) until float valve 13.

The gravity of garden tube 4 and act on the component vertically downward of hydraulic pressure thereon all passes to rubber seal 11, makes it form the horizontal plane that linear pressure compresses delivery port 8 and forms sealing.Because the diameter of section of rubber seal 11 is in 3.5 millimeter, its garden, top tube 4 rigidity are very big, therefore all equate in rigidity that goes out water-stop place each point and stress, again because the position-limiting action of spacer 5 and guide peg 6 is arranged, the position deviant of delivery port sealing place is very little, so the functional reliability of delivery port sealing place is very high.

When if the water level in the water tank 7 surpasses overfall gap 15, then the water of excess flows into closet through delivery port 8 again through overfall gap 15 inflow garden tubes 4.

In above-mentioned parts, tube plug and delivery port can be with plastics ABS or polyformaldehyde manufacturings, and automatic hook can be used the nylon 1010 manufacturing, and guide peg can be used the basis brass manufacturing, and rubber seal can be covered the manufacturing of one deck polytetrafluoroethylplastic plastic outward with butyl rubber.

Garden tube, spacer and overfall gap are a single component, and rubber seal makes its convenient maintenance and replacement with flexible organosilicon sealant build-in.The guide peg wire connection is in the copper fixings of delivery port level board; Hand switch adopts general now press type, Wrench-type and drag-line all can; It is that 40 to 50 degree, water inlet position are provided with silencing means and get final product that the water inlet float valve adopts the rotatable angle of floating ball lever.

Claims

1. the present invention is a kind of sanitary apparatus flushing device of being made up of garden tube, delivery port, automatic hook, float valve and switch, it is characterized in that choosing symmetrically at thin-walled garden tube 4 external surfaces the spacer 5 in tape guide hole; Sticking one rubber seal of embedding 11 at tube lower ending opening place, garden; Establish overfall gap 15 in garden tube upper end.
