Abstract

The utility model disclosing a toilet chair pollution discharge device includes a vertical tube and a pollution discharge bypass tube which connected with each other to from a tee structure, the intersection point forms a pollution discharge port, the top of the vertical tube and the bypass tube arranged with a opening, the bottom of the vertical tube is arranged with a bottom cover, a spring and a piston are arranged in the vertical tube, the piston divides the vertical tube into two sealed upper and lower segments, one end of the spring is connected with the bottom cover, the other end of the spring is connected with the piston, the upper end of the piston can move above and under the pollution discharge port thus to make the pollution discharge port sealed or opened. The piston of the utility model is equivalent to a cover, when the toilet chair is not used, the piston can cover the pollution discharge port and when the toilet chair is used, the piston uncovers the pollution discharge port, so the utility model has functions of odor resistance and rat resistance. In addition, because the utility model which isn't arranged with water sinking elbow is the same as the straight tube, the feces can be washed and cleaned which only need a little water thus to realize the purpose of saving water.

Description

The closet blowdown apparatus

Technical field

The utility model relates to a kind of blowdown apparatus, is specifically related to a kind of closet blowdown apparatus.

Background technology

At present, closet blowdown apparatus on the market mainly contains two kinds of structures, and a kind of to have heavy water curved, and the heavy water of a kind of not band is curved.Be not straight tube with the curved closet of heavy water owing to discharge pipe line, though easily flushing, water consumption is few, water saving, and peculiar smell is gone into after an action of the bowels, and deodorization is not enough; Though and the closet odor-resistant result that the heavy water of band is bent is good, flushing each time all needs to expend a large amount of water and ight soil could be washed away, and generally about 6 premium on currency, for today of water resource growing tension, this can't but be an open defect.Therefore, for closet blowdown apparatus of today, water saving has become a pair of contradiction with deodorization.People constantly explore and attempt to provide a kind of closet blowdown apparatus that can economize on water and can fine solution deodorization problem, but effect is all not satisfactory.The opposing party and, mouse etc. also may enter main blow-off pipe and enter the room by the closet blowdown apparatus, not only influence household's daily life, even may spread disease, health risk.To this, do not find a good solution yet.

Summary of the invention

At existing closet blowdown apparatus above shortcomings, the purpose of this utility model provides a kind of can the water saving, again can deodorization, and can stop mouse to make the device blowdown apparatus by what the closet blowdown apparatus entered the room.

The technical solution of the utility model is achieved in that the closet blowdown apparatus, it comprises VERTICAL TUBE and blowdown shunt valve, VERTICAL TUBE and blowdown shunt valve intersect the formation three-port structure, the intersection forms sewage draining exit, VERTICAL TUBE upper end and shunt valve opening, the VERTICAL TUBE lower end has bottom, in VERTICAL TUBE, be provided with spring and piston, piston is isolated into VERTICAL TUBE the two sections of sealing, spring one end is connected with bottom, the spring other end is connected with piston, thereby piston upper end can be moved the sewage draining exit sealing between up and down or opens at sewage draining exit.

Further improve being, described piston lower end is positioned at the sewage draining exit below all the time, is provided with steam vent on bottom.Angle between blowdown shunt valve and the lower-segment of vertical pipe is 15～60 °.

When using chamber pot flushing water, the active force that hydraulic pressure overcomes spring presses down piston, makes that sewage draining exit is bright to be opened, and VERTICAL TUBE and blowdown shunt valve are communicated with, and realize dirt eliminating function.And when closet time spent not, under the restoring force effect of spring, piston is pushed up to being positioned at (this is normality) on the sewage draining exit, sewage draining exit is sealed, peculiar smell and mouse by piston effectively retaining in pipeline, can't scurry out, reach the purpose of deodorization, protection against rodents.And the utility model is not with heavy water curved, and is the same with straight tube, only needs a spot of water just ight soil can be rinsed well, reached the water saving purpose.

Description of drawings

Fig. 1 is the structural representation under the utility model normality.

Fig. 2 is the structural representation under the utility model user mode.

The specific embodiment

Down and the utility model is described in further detail in conjunction with the accompanying drawings.

Referring to Fig. 1, Fig. 2, from the figure as can be seen, the utility model closet blowdown apparatus, it comprises VERTICAL TUBE 1 and blowdown shunt valve 2, VERTICAL TUBE 1 and blowdown shunt valve 2 intersect and form three-port structures, the intersection forms sewage draining exit 3.Angle between blowdown shunt valve 2 and VERTICAL TUBE 1 hypomere is to be advisable preferred 45 ° of present embodiment between 15～60 °.VERTICAL TUBE upper end and shunt valve opening connect closet outlet and main blow-off pipe respectively.VERTICAL TUBE 1 lower end has bottom 4, and bottom 4 is provided with steam vent 5.Be provided with spring 6 and piston 7 in VERTICAL TUBE 1, spring 6 one ends are connected with bottom 4, and spring 6 other ends are connected with piston 7, and piston 7 is isolated into VERTICAL TUBE 1 two sections of sealing.Piston 7 lower ends are positioned at sewage draining exit 3 belows all the time, to avoid sewage from the blowdown shunt valve into lower-segment of vertical pipe that flows backwards.Piston 7 upper surfaces are the inclined-plane that tilts in the same way with blowdown shunt valve 2, thereby piston 7 upper surfaces can be moved sewage draining exit 3 or sealing between sewage draining exit is about in the of 3 or be opened.The purpose that steam vent is set on the bottom is that when piston moves up and down the air of lower-segment of vertical pipe communicates with atmosphere all the time, moves thereby be beneficial to piston.

Operating principle of the present utility model: when not in use, spring and piston are in the raw, because piston weight is very little, amount of spring compression is little, this moment, the piston upper end was positioned at the sewage draining exit top, and sewage draining exit is in closed state, sees Fig. 1, piston is equivalent to a lid, and peculiar smell and muroid are sealed in the pipeline; And during water flushing closet, hydraulic action is in the piston upper surface, and hydraulic pressure overcomes the spring restoring force piston is pressed down, and sewage draining exit is revealed, and VERTICAL TUBE and blowdown shunt valve are communicated with, and see Fig. 2, realize dirt eliminating function.And in case stop bath, under the effect of spring restoring force, piston by on push away, be positioned at sewage draining exit top again, sewage draining exit is blocked.

Arrow among Fig. 2 is represented water (flow) direction, and as can be seen, the sewage that uses closet to produce enters this blowdown apparatus by the VERTICAL TUBE upper end from the figure, and in blowdown apparatus inside, sewage enters the blowdown shunt valve by sewage draining exit, and finally flows into main blow-off pipe and discharge.
