It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 to 11, a toilet drain device according to an embodiment of the present invention includes:
a toilet seat 10 having a bowl 11 and an injection port 111 provided at the bottom of the bowl 11;
a toilet tank 20 having a drain port 21;
a flushing water channel 40, the flushing water channel 40 is upwards communicated with the water outlet 21 and downwards communicated with the jet orifice 111, the water outlet 21 is the inlet of the flushing water channel 40, and the jet orifice 111 is the outlet of the flushing water channel 40;
a drain control valve 30 provided at a lower portion of the flushing water channel 40, the drain control valve 30 having a valve port 314 for communicating the water outlet 21 and the injection port 111, the drain control valve 30 being in a state of closing the valve port 314 in an initial state so that water can be stored in a space between the valve port 314 and the water outlet 21 in the flushing water channel 40;
an actuator 50 controls the opening of the drain control valve 30.
According to the toilet drain device of the present invention, by providing the drain control valve 30 at the lower portion of the flushing water course 40 and allowing the valve port 314 of the drain control valve 30 to communicate with the inlet and outlet of the flushing water course 40, the drain control valve 30 is in a state of closing the valve port 314 in an initial state of no flushing, so that water can be stored in the space between the valve port 314 and the drain port 21 in the flushing water course 40. The stored water cannot flow away from the valve port 314, so that air in the flushing water channel 40 between the valve port 314 and the water outlet 21 can be discharged, on the one hand, the potential energy of water in the toilet water tank 20 can be directly transmitted to the lower part of the flushing water channel 40, and compared with a toilet drainage device without stored water in the flushing water channel 40 in the prior art, the energy loss of water flow is greatly reduced, and the flushing performance of a toilet is effectively improved; on the other hand, because the water discharge control valve 30 is utilized to control the valve port 314 to be closed so that the flushing water channel 40 can keep 'stored water', compared with the water discharge device of a toilet which keeps 'stored water' by utilizing the atmospheric pressure in the prior art, the starting force value of the water discharge control valve 30 is opened and is not influenced by the atmospheric pressure, the downward pulling force of the 'stored water' on the water discharge control valve 30 is not needed to be overcome, the starting force value is smaller, and the use experience is better.
Referring to fig. 1 and 2, in the present embodiment, the toilet seat 10 and the toilet tank 20 are integrally formed, and the toilet tank 20 is located on the top surface of the rear portion of the toilet seat 10, however, the toilet seat 10 and the toilet tank 20 may be separate structures.
Referring to fig. 2, in the present embodiment, in an initial state, the toilet tank 20 is in communication with the flushing channel 40 through the drain port 21. In this way, after the flushing is finished, the water inlet valve (not shown) of the toilet tank 20 re-supplements the inner cavity of the toilet tank 20, and the water can flow into the flushing water channel 40 through the water outlet 21 to re-supplement the flushing water channel 40 at the same time, so that an additional channel for supplementing the flushing water channel 40 is not required, and the structure is simpler. Meanwhile, when flushing, water of the toilet tank 20 can directly and rapidly flow to the flushing channel 40 through the water discharge port 21.
With continued reference to fig. 2, in this embodiment, the toilet 11 has a water seal 112 formed at the bottom thereof, and the valve port 314 and the jet port 111 are both positioned below the water level of the water seal 112.

Of course, in other embodiments, the valve port 314 may alternatively be located above the water level of the water seal 112, so that a small amount of air may exist between the valve port 314 and the injection port 111, which is less effective than the solution in which both the valve port 314 and the injection port 111 are located below the water level of the water seal 112.
With continued reference to FIG. 2, in this embodiment, the valve port 314 is disposed adjacent to the injection port 111. By bringing the valve port 314 close to the injection port 111, the potential energy of the water in the toilet tank 20 can be more directly conducted to the injection port 111, facilitating the design of the valve port 314 and the installation of the drain control valve 30. Specifically, the bottom of the urinal 11 is provided with a spray head 12 with two ends penetrating, the inner end of the spray head 12 forms a spray orifice 111, the outer end of the spray head 12 is in sealing communication with a valve port 314, specifically, the outer end of the spray head 12 is sleeved in a valve outlet 313 described below, and the outer end of the spray head 12 is in sealing connection with the valve outlet 313 through a corrugated sealing sleeve 70.

By providing the spray head 12 such that one end of the spray head 12 is the spray port 111 and the other end is matched with the drain control valve 30, the structure is simple, and easy to realize, so that the drain control valve 30 is convenient to install. In other embodiments, the outer end of spray head 12 may also be used directly as valve port 314 of drain control valve 30.

The valve element 32 and the delay mechanism 33 are provided on the valve body 31. The delay mechanism 33 is arranged on the valve body 31 of the drain control valve 30, and the structure is simpler and more compact. In addition, the communication pipe 41 is independently formed with respect to the toilet seat 10, which facilitates the assembly between the drainage control valve 30 and the communication pipe 41.

Referring to fig. 3 and fig. 6 to 11, in the present embodiment, the valve core 32 includes a valve rod 321 and a valve plate 322 connected to one end of the valve rod 321, the valve plate 322 and the valve port 314 are in sealing fit through a sealing gasket 335, the sealing gasket 335 is installed on the valve plate 322, the other end of the valve rod 321 penetrates out of the delay chamber 332, a piston portion 323 is disposed on the valve rod 321, and the piston portion 323 and the delay chamber 332 are matched to compress water in the delay chamber 332. The piston portion 323 is provided with a through hole 3231, the check valve 334 is slidably disposed in the through hole 3231, when the valve core 32 moves in the direction of opening the valve port 314, the flow cross-sectional area of the delay passage 331 formed between the check valve 334 and the piston portion 323 is larger, and when the valve core 32 moves in the direction of closing the valve port 314, the flow cross-sectional area of the delay passage 331 formed between the check valve 334 and the piston portion 323 is smaller. The delay passage 331 is formed between the check valve 334 and the piston part 323, so that the design is ingenious, the structure is simple, and the delay function is reliable.
Referring to fig. 5, 8 and 11, in this embodiment, the check valve 334 includes a spool 3341 and a valve disc 3342, and the spool 3341 is provided with an axially extending flow-through groove 33411. The valve column 3341 is penetrated in the through hole 3231, the valve disc 3342 is matched with one end face of the through hole 3231, a gap H between the valve disc 3342 and one end face of the through hole 3231 and the overflow groove 33411 form a delay passage 331 (shown in fig. 11), when the valve core 32 moves towards the direction of opening the valve port 314, the one-way valve 334 moves to the end face of the valve disc 3342 far away from the through hole 3231 under the action of water pressure, so that the gap H between the valve disc 3342 and one end face of the through hole 3231 is larger (shown in fig. 8), and the overflow cross section area of the delay passage 331 is larger; when the valve core 32 moves towards the direction of closing the valve port 314, the check valve 334 moves under the action of water pressure until the valve disc 3342 abuts against one end face of the through hole 3231, so that a gap H between the valve disc 3342 and one end face of the through hole 3231 is smaller (as shown in fig. 11), and thus the through-flow cross-sectional area of the delay passage 331 is smaller, and at this time, the through-flow cross-sectional area of the gap H is smaller than the through-flow cross-sectional area of the through-flow groove 33411. The check valve 334 includes a spool 3341 and a valve disc 3342, and is configured to control the size of the flow cross-sectional area of the delay passage 331 by the valve disc 3342 being away from and abutting against an end surface of the through hole 3231. In this embodiment, the bottom surface of the piston portion 323 is provided with a protrusion 3232, and the valve disc 3342 abuts against the protrusion 3232 so that a gap H is formed between the valve disc 3342 and one end surface of the through hole 3231.
The working procedure of this embodiment is briefly described as follows:
as shown in fig. 6 to 8, at this time, the valve body 32 of the drain control valve 30 is kept closed by the elastic member 333 and the water pressure, that is, the drain control valve 30 is in a closed state, so that the space between the valve opening 314 and the drain opening 21 of the flushing channel 40 has water, and since the valve opening 314 and the injection opening 111 are positioned below the water level of the water seal 112 of the toilet seat body 10, the flushing channel 40 between the valve opening 314 and the injection opening 111 is also filled with water, that is, the entire flushing channel 40 is filled with water in an initial state;
as shown in fig. 2 and 9, when the toilet seat 10 needs to be flushed, the actuating member 50 is pressed, the actuating member 50 drives the swing lever 60 to swing, and the swing lever 60 drives the valve core 32 to open the valve port 314, so that water in the toilet tank 20 and water in the flushing water channel 40 flow to the injection port 111 to perform injection flushing on the bottom of the toilet bowl 11. When the valve core 32 moves towards the direction of opening the valve port 314, the piston 323 on the valve core 32 compresses the delay cavity 332, the one-way valve 334 moves to the end face of the valve disc 3342 far away from the through hole 3231 under the action of water pressure, so that a gap H between the valve disc 3342 and the end face of the through hole 3231 is larger, the flow cross section area of the delay channel 331 is larger, and then water in the delay cavity 332 can flow into the flushing water channel 40 through the delay channel 331 faster, and the valve core 32 can open the valve port 314 fast;
as shown in fig. 10 and 11, after the starting member 50 is released, the valve core 32 moves towards the direction of closing the valve port 314 under the action of the elastic force of the elastic member 333, at this time, the check valve 334 moves to the end face of the valve disc 3342 abutting against the through hole 3231 under the action of water pressure, so that the gap H between the valve disc 3342 and the end face of the through hole 3231 is smaller, i.e. the cross-sectional area of the delay passage 331 is smaller, so that the water in the flushing water channel 40 slowly flows into the delay cavity 332 through the delay passage 331, and the valve core 32 can delay closing the valve port 314, thereby ensuring enough drainage duration.
Finally, the toilet tank 20 is refilled with water, which can flow into the flushing channel 40 through the drain port 21, and the flushing channel between the valve port 314 and the drain port 21 is filled with water because the valve port 314 is in a closed state. Meanwhile, after the toilet seat 10 is drained, the water sealed by the water seal is also replenished, and the water sealed by the water seal can enter the flushing water channel through the injection port 111, so that the flushing water channel 40 between the valve port 314 and the injection port 111 is also filled with water, and the whole flushing water channel 40 is filled with water in an initial state so as to prepare for the next flushing.
In other embodiments, the delay channel 331 may be directly formed by an through-flow orifice provided on the wall of the delay chamber 332 or on the valve core 32; alternatively, in other embodiments, the delay passage 331 is formed by an over-flow gap formed between the walls of the delay chamber 332 and the spool 32. The delay channel 331 is simple in structure and easy to set.
In other embodiments, the drain control valve 30 may also employ an electrically controlled valve, wherein the electrically controlled valve controls the valve port 314 to open for a predetermined period of time and then closes the valve port 314, and the actuator 50 is electrically connected to the electrically controlled valve. The electronic control valve is adopted to directly control the opening time of the valve port 314, so that the structure is simple, and the control is reliable.
