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, under the condition that the float applies upward pulling force to the drain valve, the buoyancy borne by the float when the water in the water tank is at any water level cannot overcome the water pressure of the water in the water tank to the drain valve, the self weight of the drain valve and the negative pressure formed when the pre-stored water in the injection pipeline reaches the highest water level, so that the float is full of 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 be opened, and therefore the situation that the float drives the drain valve to be opened to waste water when the drain valve does not need to be opened can be avoided.
3. Because the floater is also configured to be under the condition that the floater applies upward pulling force to the drain valve, when water in the water tank is at any water level, the buoyancy borne by the floater cannot overcome the water pressure of the water in the water tank to the drain valve, the self weight of the drain valve and the negative pressure formed when the basin cavity is filled with water and the pre-stored water in the injection pipeline reaches the highest water level, the floater blocks the closestool, namely when the negative pressure in the injection pipeline reaches the minimum, the floater cannot drive the drain valve to open, and therefore, the condition that the floater drives the drain valve to open when the drain valve does not need to be opened, and further water flow in the closestool overflows the basin cavity is avoided.
4. Because the floater 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 floater applies upward tension to the drain valve, under the water level, the buoyancy borne by the floater can overcome the water pressure of the water in the water tank on the drain valve and the self weight of the drain valve, so that the floater has no pre-stored water in the injection pipeline, namely when no negative pressure exists in the injection pipeline, the floater can drive the drain valve to open to replenish water in the injection pipeline; therefore, the arrangement avoids the trouble that a user manually replenishes the water filling valve for the spraying pipeline when the toilet is used for the first time, and provides greater convenience for the user.
5. Because the floater is connected with the drain valve pull rope, the floater exerts upward pulling force on the drain valve when the pull rope is at least stretched when the water level of the water tank reaches the highest water level, and therefore the arrangement can play a role in reducing the pulling force for opening the drain valve; in addition, the float and the drain valve in the embodiment are connected through only one pull rope; therefore, the implementation mode has the characteristics of simple operation and easy realization.
6. The water-saving closestool is characterized in that a first barrel is further arranged in the water tank and is in sealed connection with the injection pipeline, a water inlet is formed in the barrel wall of the first barrel, the drain valve is in sliding connection with the inner wall of the first barrel, one end of the air inlet pipe penetrates through the drain valve and is in sealed fixed connection with the drain valve, the other end of the air inlet pipe extends out of the highest water level of the water tank, an air inlet valve used for opening and closing the air inlet pipe and communicated with the atmosphere is arranged on the air inlet pipe, and a floater is fixed on the air inlet pipe, so that air enters the injection pipeline from the air inlet pipe after the air inlet valve is opened, negative pressure in the injection pipeline is eliminated or reduced until the floater can drive the drain valve; thus, this arrangement provides another embodiment that can be used to address the difficulty of opening a pre-flush toilet drain valve.
7. 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 in one end, extending out of the highest water level of the water tank, of the air inlet pipe, 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 self gravity and blocks the opening; thus; this setting provides the concrete structure of an admission valve to the effect that the admission valve opened and close intake pipe and atmosphere intercommunication is opened and close to the realization.
8. The air inlet valve comprises a second cylinder, an upper cover, a plug, a lifting piece and a spring, an opening is formed 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 and is provided with a through hole through which the lifting piece or the plug penetrates, and the spring is arranged between the plug and the upper cover, so that when the lifting piece is lifted, the head is lowered to leave the opening, when the lifting piece is released, the spring resets, and the plug blocks 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 part, 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, a connecting part of the pressing part penetrates through a hole position to be fixedly connected with the plug in the air inlet pipe, the spring is arranged between the pressing part and the cover body, so that the plug leaves the through hole when the pressing part is pressed, the spring resets when the pulling part is released, and the plug blocks 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.

7. A pre-flush toilet according to any one of claims 1 to 6, wherein: the intake valve includes a weight and a pull-up member; the weight is connected with the lifting piece; an opening is formed in one end, extending out of the highest water level of the water tank, of the air inlet pipe; when the lifting piece is lifted, the weight leaves the opening, the air inlet pipe is communicated with the atmosphere, and when the lifting piece is released, the weight falls to block the opening to isolate the air inlet pipe from the atmosphere.
8. A pre-flush toilet according to any one of claims 1 to 6, wherein: the air inlet valve comprises a second cylinder, an upper cover, a plug, a lifting piece and a spring; an opening is formed between the second cylinder and the air inlet pipe; the upper cover is fixedly arranged on the second barrel, and a through hole for the pulling piece or the plug to penetrate through is formed in the upper cover; the spring is arranged between the plug and the upper cover; when the lifting piece is lifted, the plug leaves the opening, the air inlet pipe is communicated with the atmosphere, when the lifting piece is released, the spring resets, the plug plugs the opening, and the air inlet pipe and the atmosphere are isolated.
9. A pre-flush toilet according to any one of claims 1 to 6, wherein: the air inlet valve comprises a pressing piece, a spring, a plug and a cover body; the pressing piece comprises a pressing part and a connecting part, the cover body is fixedly arranged on the air inlet pipe, a through hole is formed in the cover body, and the connecting part penetrates through the through hole and is fixedly connected with a plug positioned in the air inlet pipe; the spring is arranged between the pressing part and the cover body; wherein, when pressing the pressing piece, the end cap leaves the via hole, and intake pipe and atmosphere intercommunication, when releasing the pull-up piece, the spring resets, and end cap shutoff via hole completely cuts off intake pipe and atmosphere.
