Description

Overflow assembly for isolating air

Technical Field

The utility model relates to a bathroom field, in particular to overflow subassembly of isolation air.

Background

In the prior art, an overflow pipe on the side edge of a drainage valve of a closestool is communicated with a drainage outlet at the bottom of the drainage valve. Under the normal stagnant water state, the outside air passes through overflow pipe and drain valve base outlet intercommunication. When the overflow phenomenon occurs, water flows from the overflow pipe to the water discharge valve base water discharge port and enters the toilet bowl pipeline. When the drain valve is opened, water flows out through the drain outlet of the drain valve base, and when the drain valve is normally used, the drain outlet of the drain valve base is communicated with outside air through the overflow pipe channel, negative pressure can be generated in the drain channel during draining, and air can be mixed into the drain outlet of the drain valve base together under the action of outside atmospheric pressure, so that the drain channel is not in a pipe full water state, and the drainage speed is reduced.

Disclosure of Invention

To the above problem, an object of the utility model is to provide an overflow subassembly of isolation air, thereby this overflow subassembly can completely cut off outside air entering drain valve outlet accelerate the drainage rate of drain valve.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides an overflow assembly of keep apart air, includes overflow base and flotation pontoon, the overflow base include the drainage portion and set firmly the portion of intaking at the drainage portion top. The inside of drainage portion is provided with the drainage channel who link up from top to bottom, the inside of water inlet portion is provided with the inhalant canal that link up from top to bottom, inhalant canal and drainage channel are linked together. The flotation pontoon is established but activity from top to bottom in the inhalant canal, flotation pontoon bottom opening and top seal, flotation pontoon bottom and the sealed cooperation in drainage channel top. The inhalant canal top is equipped with and is used for right the limit structure that the come-up stroke of flotation pontoon carries out the restriction.

Further, in order to realize better sealing effect, an annular groove is formed in the top of the water discharging part, an annular sealing rubber gasket is installed in the annular groove, and the bottom of the floating barrel is in sealing fit with the annular sealing rubber gasket.

Furthermore, limit structure include along the circumference of the top of inhalant canal internal surface evenly lays a plurality of spacing boss.

In one embodiment, in order to prevent the bottom end surface of the float from separating from the circular size range of the annular sealing rubber gasket when the float moves up and down along the water inlet channel, the sealing failure is caused, and air cannot be isolated. The difference of flotation pontoon external diameter and inhalant canal internal diameter is less than the difference of flotation pontoon groove inscribe circle diameter of stepping down and ring channel internal diameter.

In another embodiment, a guide structure for guiding the buoy when the buoy moves up and down is fixedly arranged in the water inlet channel, the guide structure comprises guide ribs uniformly distributed along the circumferential direction of the inner side and/or the outer side of the buoy, and the bottom of each guide rib is fixed to the top of the drainage part.

Preferably, in order to prevent the buoy from deviating in the whole floating travel range, the height value of the guide rib is larger than the height difference value between the water inlet channel and the buoy.

Furthermore, a guide pipe for communicating the water replenishing pipe with the drainage channel is fixedly arranged on the side wall of the drainage part.

The drainage pipe is arranged in the drainage channel, the drainage pipe is bent upwards to form a water storage branch pipe, a water replenishing elbow joint is detachably mounted at the top of the water storage branch pipe, and a water outlet of the water replenishing elbow joint is arranged in a downward inclined mode. When the overflow assembly supplies water, a water storage bay is formed among the water supply elbow joint, the water storage branch pipe, the flow guide pipe and the water supply pipe, and external air can be isolated from the stored water in the water storage bay and enters the overflow port.

Preferably, the upper end of the buoy is an arc top with a slope. The purpose of setting the arc top is as follows: the overflow area is increased, and the flow guide function is also realized, so that the discharge speed is accelerated.

The utility model discloses following beneficial effect has:

1. under the normal condition, the flotation pontoon has kept apart the drain valve outlet and has communicated with each other with the outside air because of the sealed cooperation in action of gravity and drainage portion top, and the outside air can't enter into in the drain, and the outlet is in full pipe water state almost, makes drainage speed improve by a wide margin through siphon effect. When the water level overflows the floating cylinder by a certain height, the floating cylinder floats upwards and opens the drainage channel to realize overflow.

The water tank 6 is normally in a full water state, the working water level line is lower than the overflow water level line, the buoy 2 is in a closed state due to the action of gravity, and the drainage outlet of the drainage valve is isolated from being communicated with the outside air, so that the drainage outlet of the drainage valve base is always in a full pipe water state, and the drainage flow rate is improved (fig. 18). When the water inlet valve 4 does not stop water and water is continuously fed, the water tank 6 overflows, when the water level of the water tank 6 rises and overflows the buoy 2 for a certain height, the buoy 2 starts to float upwards, water flows into the overflow pipe 50 from an overflow port, and the water flows into a toilet pipeline to realize overflow (figure 19).
