Description

Straight toilet stool washing device

Technical field the present invention relates to a kind of tank for excrement pan.

It is a great problem that background technology tank for excrement pan draining valve leaks, and its main cause is that draining valve adopts the hermetically-sealed construction of relative engagement between valve plug and the valve seat.Therefore people avoid the research to draining valve, tipping bucket type and drum-type flushing cistern have successively been invented, a turnover tipping bucket or a cylinder of being filled with water promptly is set in water tank, though it can prevent radiator leak effectively, but also have following weak point: no matter be tipping bucket or cylinder 1., they all are subjected to the specified just restriction of the water yield of dashing, and volume and raw water box are similar, establish tank shell again in their outsides and not only make the water tank huge heaviness that seems, and increased cost of production.2. the quality of fit between the parts is had relatively high expectations, and all brings very big difficulty for assembling and maintenance.3. can only with the supporting use of special water box, lack versatility, be unfavorable for penetration and promotion.

Summary of the invention the object of the present invention is to provide and neither establishes the straight toilet stool washing device that water container has solved the draining valve seepy question again in a kind of water tank in addition.This is located at the water trap that replaces draining valve in the raw water box in the water tank, mainly includes: base, sleeve, pipe box, telescoping tube and telescoping tube compressing mechanism.Wherein, can be inserted in the base short tube in the water tank outlet, the radial location bulge loop at its middle part may be stuck in the inboard of water tank, below positioning convex ring, establish outside the bindiny mechanism that base can be fixed on the water tank such as the short tube and be provided with screw thread, establish nut engaged with it on it, or establish by the fixing pipe of spoke type connecting plate at the middle part in the short tube, and it reaches the securing member that the outer part of water tank is provided with middle part screw and its engagement with the screw of its internal thread engagement.This base positioning convex ring top also is provided with two radial convex loops, and wherein adjacent with positioning convex ring big bulge loop is provided with the coupled vertical sleeve in lower end, and this can be telescoping tube sleeve spacing and guiding is the barrel-type casing that through hole is arranged on the barrel.The little bulge loop of above-mentioned base upper end is provided with tube wall and is undulatory telescoping tube lower end, should be located on the mouth of pipe of pipe box lower end by the telescoping tube upper end that elastomeric material is made, this pipe box is made up of opening part and top ring pipe thereof, and it can be the single annular pipe, also can be jacket pipe.Be provided with the telescoping tube compressing mechanism on this pipe box top, this compressing mechanism can adopt multiple form of structure, as lever, and gear and connecting rod and wheel and rack etc.When needs dash just, apply a downward power by this telescoping tube compressing mechanism to pipe box, so being pressed downward, telescoping tube contracts, the water level that originally is positioned in the water tank under the limit, the outer upper end of pipe box just is higher than limit, pipe box upper end, so the water in the water tank just enters in the telescoping tube, is discharged in the urinal via following base.When the water level in the water tank was concordant with limit, pipe box above compressed telescoping tube upper end, bath stopped, and telescoping tube gos up under the buoyancy acting in conjunction of self elastic force and pipe box, returns to original position.And water tank injects clear water by conventional water intake mechanism, ends in the time of on being lower than pipe box.Be using water wisely, be preferably in the mechanism that establishes the control displacement on the above-mentioned syringe.It is the part that is provided with axial evagination on sleeve, also be provided with on the pipe box in the sleeve and the corresponding axial projection of this axial evagination part, be provided with female parts on the outer wall below this axial projection, it can be corresponding with the free end of bayonet lock, this passes the bayonet lock of the set strip through-hole of the outside convex portion of quill, flexibly connect by bearing pin and the axle bed that is located at the sleeve middle part, be provided with float lever and the little float that is connected as a single entity with bayonet lock at the axle bed opposite side.When dashing urine, when coming downwards to the bayonet lock place, the pipe box female parts just blocks by bayonet lock, so just entering in the telescoping tube, the water in the water tank discharges, since to toilet drainage, the drawdown in the water tank, and little float is then downward-sloping, coupled bayonet lock is then tilted upward, and loses the jam effect.So they return to original position again under the buoyancy acting in conjunction of telescoping tube self elastic force and pipe box.Pipe box is descending when dashing stool, block by bayonet lock when end pushes up to pin place, bayonet lock place, below process with dash urine in like manner.

The present invention has following advantage compared to existing technology:

1. though the present invention is simple in structure, cost of production is low, can solve the seepy question of tank for excrement pan effectively.

Can with the supporting use of existing tank for excrement pan, highly versatile is beneficial to penetration and promotion.
