From the above description of the present invention, compared with the prior art, the present invention has the following advantages:
1. because the pre-stored water closestool is also provided with the air inlet pipe in the water tank, one end of the air inlet pipe is communicated with the injection pipeline, the other end of the air inlet pipe extends out of the highest water level of the water tank, and the air inlet valve is arranged on the air inlet pipe, after the air inlet valve is opened, air can enter the injection pipeline from the air inlet pipe to eliminate or reduce negative pressure in the injection pipeline until the float can drive the drain valve to be automatically opened; therefore, this arrangement can solve the problem that the drain valve is difficult to open.
2. Because the float connected with the drain valve is arranged in the water tank and is configured to apply upward pulling force to the drain valve at least when the water level of the water tank reaches the highest level, the float can play a role in reducing the pulling force for opening the drain valve; in addition, because the float is configured under the condition that the float applies upward tension to the drain valve, when the water in the water tank is at any water level, the buoyancy force born by the float cannot overcome the water pressure caused by the water in the water tank to the drain valve, the dead weight of the drain valve and the negative pressure formed when the pre-stored water in the injection pipeline reaches the highest water level, the float is filled with water in the injection pipeline, namely, when the negative pressure in the injection pipeline reaches the maximum, the float cannot drive the drain valve to open, so that the condition that the float drives the drain valve to open when the drain valve is not required to open can be avoided.
3. Because the float is also configured to be under the condition that the float applies upward tension to the drain valve, when the water in the water tank is at any water level, the buoyancy force born by the float cannot overcome the water pressure caused by the water in the water tank to the drain valve, the dead weight of the drain valve and the negative pressure formed when the water in the basin cavity is full of water and the pre-stored water in the injection pipeline reaches the highest water level, the float is blocked in the toilet, namely, when the negative pressure in the injection pipeline is minimum, the float can not drive the drain valve to open, so that the situation that the float drives the drain valve to open when the drain valve is not required to open, and then water in the toilet overflows the basin cavity is further avoided.
4. Because the float is also configured to have at least a first water level lower than or equal to the highest water level of the water tank in the water tank under the condition that the float applies upward tension to the water drain valve, under the water level, the buoyancy of the float can overcome the water pressure of the water in the water tank to the water drain valve and the dead weight of the water drain valve, so that the float can drive the water drain valve to be opened to supplement water to the injection pipeline when no pre-stored water exists in the injection pipeline, i.e. no negative pressure exists in the injection pipeline; therefore, the setting avoids the trouble of manually supplementing the water valve for the spraying pipeline when the toilet is used for the first time, and provides greater convenience for users.
5. Because the floater is connected with the draw-off valve pull rope, the pull rope can exert upward pulling force on the drain valve at least when the water level of the water tank reaches the highest water level to be straightened, and the device can play a role in reducing the pulling force for opening the drain valve; furthermore, since the float and the drain valve in this embodiment are connected by only one string; therefore, the embodiment has the characteristics of simple operation and easy realization.
6. Because the pre-stored water closestool is also provided with the first barrel in the water tank, the first barrel is in sealing connection with the injection pipeline, the barrel wall of the first barrel is provided with a water inlet, the water discharge valve is in sliding connection with the inner wall of the first barrel, one end of the air inlet pipe penetrates through the water discharge valve and is in sealing and fixed connection with the water discharge valve, the other end of the air inlet pipe stretches out of the highest water level of the water tank, an air inlet valve for opening and closing the air inlet pipe and communicating with the atmosphere is arranged on the water inlet pipe, and the floater is fixed on the air inlet pipe, so that after the air inlet valve is opened, air enters the injection pipeline from the air inlet pipe, so that negative pressure in the injection pipeline is eliminated or reduced until the floater can drive the water discharge valve to move upwards to open the water discharge valve, and water in the water tank can flow into the injection pipeline from the water inlet to supplement the injection pipeline; thus, this arrangement provides another embodiment that can be used to address the difficulty of opening the pre-stored water toilet drain valve.
7. Because the air inlet valve comprises a heavy object and a lifting piece, the heavy object is connected with the lifting piece, and an opening is formed at one end of the air inlet pipe, which extends out of the highest water level of the water tank, so that when the lifting piece lifts the heavy object, the heavy object leaves the opening, the air inlet pipe is communicated with the atmosphere, and when the lifting piece is released, the heavy object naturally falls under the gravity of the heavy object and plugs the opening; thus, the method comprises the steps of; this setting provides a specific structure of admission valve to realize the effect that admission valve opens and close intake pipe and atmosphere intercommunication.
8. Because the air inlet valve comprises the second cylinder, the upper cover, the plug, the lifting piece and the spring, an opening is arranged between the second cylinder and the air inlet pipe, the lifting piece is connected with the plug, the upper cover is fixedly arranged on the second cylinder, a through hole for the lifting piece or the plug to penetrate is formed in the upper cover, the spring is arranged between the plug and the upper cover, when the lifting piece is lifted, the lower head leaves the opening, when the lifting piece is released, the spring is reset, and the plug plugs the opening; therefore, the arrangement provides another specific structure of the air inlet valve so as to realize the effect that the air inlet valve opens and closes the air inlet pipe to be communicated with the atmosphere.
9. The air inlet valve comprises a pressing piece, a spring, a plug and a cover body, wherein the cover body is fixedly arranged on the air inlet pipe and is provided with a through hole, the connecting part of the pressing piece penetrates through the hole and is fixedly connected with the plug in the air inlet pipe, and the spring is arranged between the pressing part and the cover body, so that when the pressing piece is pressed, the plug leaves the through hole, and when the lifting piece is released, the spring is reset, and the plug plugs the through hole; therefore, the arrangement provides another specific structure of the air inlet valve so as to realize the effect that the air inlet valve opens and closes the air inlet pipe to be communicated with the atmosphere.
10. Because the drain valve is a push type drain valve, the air inlet valve is a push type air inlet valve, the pre-stored water closestool is provided with a mechanical button, a first pressing rod and a second pressing rod which extend towards the drain valve and the air inlet valve are respectively arranged on the mechanical button, and the distance from the first pressing rod to the drain valve is larger than the distance from the second pressing rod to the air inlet valve, the effect that the air inlet valve and the drain valve are opened successively can be achieved by only pressing the mechanical button once by a user, and therefore, the negative pressure in the injection pipeline can be eliminated or reduced before the drain valve is opened; therefore, the setting not only brings convenience to the user, but also effectively solves the problem that the user is difficult to drive the drain valve.
