Description

Overflow arrangement of air isolation and area moisturizing function

Technical Field

The utility model relates to a bathroom field, in particular to air isolation and overflow arrangement who takes moisturizing function.

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.

SUMMERY OF THE UTILITY MODEL

To the above problem, an object of the utility model is to provide an overflow arrangement of isolation air and area moisturizing function, thereby this overflow arrangement can completely cut off outside air entering drain valve outlet accelerate the drainage speed of drain valve.

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

an overflow device with air isolation and water supplementing functions comprises an overflow base and a floating barrel arranged above the overflow base. The overflow base include drainage portion and establish the portion of intaking at the drainage portion top, the bottom surface of portion of intaking for the outer wall of drainage portion is outside salient, the inside of overflow base is provided with and link up completely the drainage channel of portion of intaking and drainage portion. The floating cylinder comprises a floating cylinder body and a plurality of guide ribs distributed along the circumferential direction of the bottom of the floating cylinder body, and the bottom of the floating cylinder body is in sealing fit with the top of the drainage channel. The guide ribs are uniformly distributed around the outer side of the overflow base, and the inner sides of the guide ribs are fixedly provided with hooks used for interfering with the bottom surface of the water inlet part for limiting when the floating pontoon floats upwards.

Further, the flotation pontoon body include the roof and certainly the annular curb plate that roof bottom downwardly extending formed, annular curb plate cover establish the outside of portion of intaking, the height of annular curb plate is less than the height of direction rib.

Preferably, in order to better realize the sealing, an annular groove is formed in the bottom of the top plate, an annular sealing rubber gasket is installed in the annular groove, and the top of the water inlet part is in sealing fit with the annular sealing rubber gasket.

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 device is used for replenishing water, a water storage bay is formed among the water replenishing elbow joint, the water storage branch pipe, the flow guide pipe and the water replenishing pipe, and external air can be isolated from water stored in the water storage bay and enters the overflow port.

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 channel 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 the 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.

2. Through setting up the direction rib and setting up the pothook at direction rib bottom inboard, the setting of pothook can prevent that the flotation pontoon from droing from the overflow base, further strengthens overflow arrangement's stability and reliability.

3. Through set up honeycomb duct, water storage branch pipe and detachable moisturizing elbow joint at the drain part side, during the overflow arrangement moisturizing, constitute a trap between moisturizing elbow joint, water storage branch pipe, honeycomb duct and the moisturizing pipe, the retaining in the trap can keep apart in the outside air gets into the overflow mouth to avoid in running into the drain valve drain because of the air, cause the drainage speed to reduce. The delivery port downward sloping setting of moisturizing elbow joint can avoid the moisturizing rivers to break away the flotation pontoon when too big to cause sealed inefficacy, simultaneously, the existence of moisturizing elbow joint can let the water effect of depositing of trapped water bay better. The water replenishing elbow joint can have different inner diameter specifications, can realize different water replenishing rates, and can be selected and matched with the water replenishing elbow joint with the proper inner diameter according to the water replenishing quantity of the toilet.

4. The utility model discloses an overflow arrangement both can install in the overflow pipe of drain valve, realizes the function of isolated air and overflow, also can install alone in the water tank bottom, realizes overflow and moisturizing function.
