In this embodiment, the check valve 23 is a water sealing sheet; the water sealing sheet is made of soft materials, and one side of the water sealing sheet is fixed at the edge of the opening 212.

Preferably, the water inlet of the siphon elbow 22 is flared.
The working principle and process of the embodiment are briefly described as follows:
when the toilet 1 needs to be flushed, under the condition that a pressure water source can provide enough water pressure for the water spray pipe 52, only the water spray pipe 52 needs to be filled with water, so that the nozzle 51 sprays pressure water to the water inlet of the siphon elbow 22, the water in the siphon cavity 211 flows into the siphon elbow 22 under the venturi effect, and then the water is discharged into the toilet 1 through the siphon elbow 22 to flush the toilet 1. That is, when the pressure water source can provide normal water pressure, only the water spraying assembly 50 needs to be turned on.
As shown in fig. 6 and 7, when the toilet 1 needs to be flushed and the pressure water source cannot provide enough water pressure to the spray pipe 52, on one hand, the spray pipe 52 is supplied with water, the nozzle 51 sprays pressure water to the inlet of the siphon elbow 22, and the water in the siphon cavity 211 flows into the siphon elbow 22 under the venturi effect; on the other hand, the air pump 36 is started, the air pump 36 delivers air to the bag body 34, the bag body 34 expands and deforms, so that the piston 32 is driven to move downwards, water in the pressurizing cavity 311 is extruded into the siphon cavity 211 in the downward moving process of the piston 32, the water in the siphon cavity 211 is extruded to enter the siphon elbow 22, once the siphon elbow 22 is full of water, siphon is formed, water in the siphon cavity 211 can be continuously pumped into the toilet 1, normal use of the toilet flushing device in a low water pressure period or a low water pressure area can be guaranteed under the combined action of the water spraying component 50 and the pressurizing component 30, the flushing effect is good, the structure is simple, and the universality is good. During pressurization, the water sealing flap (check valve 32) seals the opening 212 under the water pressure in the siphon chamber 211. When the siphon causes the water pressure in the siphon chamber 211 not to be enough to cause the water sealing sheet (one-way valve 32) to seal the opening 212, the water in the water storage chamber 11 of the water tank 10 enters the siphon chamber 211 from the opening 212, and the siphon of the siphon elbow 22 can be maintained until the water level in the water storage chamber 11 drops to the point where the air enters the siphon elbow 22 to break the siphon.
As shown in fig. 8 and 9, after the toilet 1 is flushed, the air pump 36 is turned off, the elastic member 33 is reset to drive the piston 32 to move upwards and reset, the piston 32 further compresses the capsule 34 to make the capsule 34 contract and deform, the water tank 10 also starts to fill water, when the water level in the water storage chamber 11 rises to the position of the opening 212, water flows into the siphon chamber 211 through the opening 212, and further enters the pressurizing chamber 311 from the siphon chamber 211, so that the whole device returns to the initial state.
Referring to fig. 11, in other embodiments, the bladder of the pressurizing assembly 30 may be replaced by a piston cylinder 35, specifically, the piston 32 is slidably disposed in the piston cylinder 35, the piston 32 slides under the air pressure of the gas filled in the piston cylinder 35 or under the hydraulic pressure of the liquid, and the elastic member 33 drives the piston 32 to reset so as to extrude the gas or the liquid in the piston cylinder 35.
The hydraulic pressure in this embodiment is provided by mains water and the piston 32 is a piston plate.
Referring to fig. 12, in another embodiment, in order to make the pressurizing effect of the tap water better, the piston 32 is designed to be i-shaped and divides the pressurizing chamber 311 into a first chamber 3111 and a second chamber 3112 which are not communicated with each other, the piston 32 includes a first piston plate 321, a second piston plate 322, and a connecting rod 323 connecting the first piston plate 321 and the second piston plate 322, a cross-sectional area of the first piston plate 321 is smaller than a cross-sectional area of the second piston plate 322, the first piston plate 321 and the second piston plate 322 are respectively in sealing sliding fit with an inner wall of the pressurizing chamber 311, the first piston plate 321 and the inner wall of the pressurizing chamber 311 enclose a first chamber 3111, the second piston plate 322 and the inner wall 3112 of the pressurizing chamber 311 enclose a second chamber 3112, the tap water flows into the first chamber 3111, and the second chamber 2 is communicated with the siphon chamber 211. By designing the piston 32 as a first piston plate 321 and a second piston plate 322 with different cross-sectional areas, the requirement for the water pressure of the tap water can be reduced.
According to the invention, through arranging the siphon component 20 comprising the siphon container 21 and the siphon elbow 22, arranging the pressurizing component 30 and the water spraying component 50, the water inlet of the siphon elbow 22 is communicated with the siphon cavity 211 of the siphon container 21, the water outlet of the siphon elbow 22 is communicated with the washing water path of the 1, and the water in the siphon cavity 211 is extruded into the siphon elbow 22 through the pressurizing component 30 so that the siphon elbow 22 forms siphon, so that siphon drainage is realized, therefore, under the condition that the water pressure sprayed out by the spraying component 50 is insufficient, the pressurizing component 30 can be adopted for assisting drainage, normal use in a low water pressure period or a low water pressure area is ensured, the washing effect is good, the structure is simple, and the universality is good.
