Description

FIELD OF THE INVENTION

The invention relates to a quick water discharging device of a toilet tank, and more particularly to a quick water discharging device capable of reducing air resistance during water discharging.

BACKGROUND OF THE INVENTION

In the field of flush toilets, there are related water discharging structures such as overflow pipes, water discharging pipes, and water stoppage devices in the water tank, and a water stoppage valve is the main controller of water outlet from the water tank. The relevant content of the water discharging structures can be found in CN 206503204U, CN 2466254Y and CN 103590467A.

When the conventional water discharging structure is implemented, the water stoppage valve is operated to stop blocking the water discharging pipe from the outside, so that the water inside the water tank can flow toward the toilet through the water discharging pipe. However, the conventional water discharging structure has the problem that it is difficult for the water in the water tank to enter into the water discharging pipe. The reason is that one end of the overflow pipe is connected to the water discharging pipe, when the water stoppage valve is opened, the air in the overflow pipe flows toward the water discharging pipe under pressure and also discharges through opening of the water discharging pipe connected to the water stoppage valve. That is to say, when the water stoppage valve is opened, the water in the water tank will flow into the water discharging pipe, and the air in the overflow pipe will be discharged from the water discharging pipe, this will cause collision between the water flow and the air, which is not conducive to rapid flow of the water into the water discharging pipe.

Taking CN 206503204U as an example, in order to solve the above-mentioned problems, the structure of the water discharging valve is provided with a water baffle facing the outlet of the overflow channel. However, the object of the water baffle is to split part of the water flowing into the water discharging channel to enter the overflow pipe, so that the water entering the overflow pipe forms a water seal at the outlet of the overflow channel, thereby preventing the air in the overflow channel from colliding with the water flowing into the water discharging channel. It can be known from the foregoing that the actual function of the water baffle of CN 206503204U is to guide the water flow, so that the water flow from the water tank partially forms a water seal, and the remaining part maintains to be discharged. However, the aforementioned structure cannot provide the function of rapid water discharge. Moreover, there is a certain distance between the water baffle and the outlet of the overflow channel, and water flow cannot be specifically restricted. In view of the drawbacks of the aforementioned water discharging structure, the applicant of the invention made every effort to develop a water discharging structure that is more conducive to rapid water discharging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The detailed description and technical content of the invention are described below with reference to the accompanying drawings.

Please refer to FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, and FIG. 6, the invention provides a quick water discharging device 100. The quick water discharging device 100 is disposed in a toilet tank (not shown in the figures), and used to control water discharging of the toilet tank. The quick water discharging device 100 includes a water discharging structure 10 and a water stoppage structure 20. The water discharging structure 10 includes a main pipe 11 and an overflow manifold 12. The main pipe 11 is provided for water discharging. The overflow manifold 12 communicates with an inner space of the main pipe 11. Serving as a water level controller in the toilet tank, the overflow manifold 12 receives an inflow of water in the toilet tank with water level higher than a set water level and discharges water through the main pipe 11. Furthermore, the main pipe 11 includes a pipe body 111 communicating with the overflow manifold 12, an inclined surface 112 disposed at one end of the pipe body 111, and a communication hole 113 disposed on the pipe body 111 and communicating with the overflow manifold 12.

The water stoppage structure 20 includes a rubber valve seat 21 located at an end of the main pipe 11 provided with the inclined surface 112, and a water stoppage valve 23 pivotally connected to the overflow manifold 12. The water stoppage valve 23 fits with the rubber valve seat 21. The water stoppage valve 23 blocks communication through the rubber valve seat 21 when the water stoppage valve 23 is not operated, and restricts the main pipe 11 from communicating with an external environment. Once the water stoppage valve 23 is operated, the water stoppage valve 23 is opened relative to the rubber valve seat 21, and the inner space of the main pipe 11 communicates with the external when the water stoppage valve 23 is opened. Furthermore, the rubber valve seat 21 is made of rubber material, which is different from the conventional technique that utilizes the valve seat made of hard material. The rubber valve seat 21 includes a seat body 211 disposed above the pipe body 111, an opening 212 formed on the seat body 211, and at least one baffle 213 extending from the seat body 211 to the inner space of the main pipe 11. The seat body 211 matches with the inclined surface 112 and is obliquely assembled with the pipe body 111. The opening 212 communicates with the inner space of the main pipe 11 and faces the water stoppage valve 23. The opening 212 is closed when the water stoppage valve 23 is not opened relative to the rubber valve seat 21. The at least one baffle 213 is close to an inner wall of the main pipe 11 and faces the communication hole 113. The at least one baffle 213 does not completely close the communication hole 113. There is a gap between the at least one baffle 213 and the communication hole 113. A function of the at least one baffle 213 is to block resisting force of an air from the communication hole 113. The at least one baffle 213 covers at least 50% of an area of the communication hole 113 to achieve an effect of blocking air resistance.

Please refer to FIG. 4, FIG. 5, and FIG. 6, implementation of the quick water discharging device 100 is described hereinafter. In an initial state, the water stoppage valve 23 is not operated and closes the opening 212, thereby blocking the inner space of the main pipe 11 to communicate with the external, as shown in FIG. 4. When the water stoppage valve 23 is operated, the water stoppage valve 23 pivots and is opened relative to the rubber valve seat 21, and the water stoppage valve 23 unblocks the opening 212, so that the inner space of the main pipe 11 communicates with the external, allowing water in the water tank to enter the main pipe 11 (as labeled in numeral “50”). At this point, the overflow manifold 12 discharges air towards the communication hole 113, the at least one baffle 213 blocks an air resistance from the communication hole 113 under an action of water pressure, so that water enters and discharges from the inner space of the main pipe 11 smoothly. When the water stoppage valve 23 pivots again and closes the opening 212, the water stoppage valve 23 blocks communication of the main pipe 11 with the external. At this moment, since the at least one baffle 213 does not completely close the communication hole 113, the overflow manifold 12 is in communication with the main pipe 11, and the overflow manifold 12 still provides water flowing therein to flow into the main pipe 11 through the communication hole 113 when the water stoppage valve 23 is not opened.

Accordingly, the invention provides the at least one baffle 213 on the rubber valve seat 21, the at least one baffle 213 is disposed close to the inner wall of the main pipe 11 and covers at least 50% of an area of the communication hole 113; thereby the problem that the conventional structures do not specifically reduce an air resistance during water discharging is solved. Furthermore, the rubber valve seat 21 of the invention is changed from the conventional hard material to a soft rubber material, which facilitates assembling of the quick water discharging device 100 and increases water discharging efficiency.

In one embodiment, in order to enhance an air blocking effect of the at least one baffle 213, the at least one baffle 213 completely covers the communication hole 113. Viewing a section of the at least one baffle 213 shown in FIG. 4, a lower edge of the at least one baffle 213 at least reaches a bottom end of the communication hole 113. The communication hole 113 is completely covered by the at least one baffle 213, and a user is disabled to look into the communication hole 113 from outside. It should be noted that, in this embodiment, the at least one baffle 213 does not close the communication hole 113, the at least one baffle 213 is only disposed near the communication hole 113 and covers the communication hole 113.
