The delay water cavity 203 cannot move relative to the valve body 202, a water passing cavity 208 is formed between the movable valve core 204 and the push rod assembly 205, the water passing cavity 208 is communicated with the first water outlet 214 or the second water outlet 224, and the delay water cavity 203 is communicated with the first water inlet 212 or the second water inlet 222, as shown in fig. 5 and 6, namely when water is not flushed, the inner cavity of the valve body 202 is divided into two chambers by the movable valve core 204, the chamber communicated with the first water outlet 214 or the second water outlet 224 is the water passing cavity 208, and the chamber communicated with the first water inlet 212 or the second water inlet 222 is the water inlet cavity 209.
As shown in fig. 5, in the flushing state, when the flush switch is pressed, the push rod assembly 205 moves along the direction of the delay water cavity 203 to drive the delay water cavity 203 to move along the inner wall thereof, so that the first water outlet 214 is communicated with the first water inlet 212 or the second water outlet 224 is communicated with the second water inlet 222, and the first water inlet 212 and the second water inlet 222 are communicated with the water inlet pipe 50, at this time, at the moment when the static pressure in the water inlet cavity 209 is released, the pressure in the valve body 202 is equal to the atmospheric pressure, the hydraulic pressure potential energy generated by the daily tap water is converted into the flushing kinetic energy, the flushing water flow is formed instantly, the pressurizing flushing force is generated, and the pressurizing flushing of the toilet bowl is realized; meanwhile, the two valve bodies respectively remove the set water quantity according to the requirement according to the delay principle. When the flush switch is released, the elastic component 206 rebounds to make the movable valve core 204 generate a tendency of moving towards the direction of approaching the flush switch 201, the movable valve core 204 moves towards the flush switch 201 under the rebounding force of the elastic component, and at this time, the water pressure in the delay water cavity 203 drains into the delay water cavity through the delay groove 2032, so that the movable valve core 204 is prevented from approaching the flush switch 201. The time for communicating the water passing cavity 208 and the water inlet cavity 209 can be controlled by controlling the elastic force of the elastic component 206 and the opening degree of the delay groove 2032, and the water passing cavity 208 and the water inlet cavity 209 are automatically closed in a delayed manner within the range of 2 to 15 seconds. The delayed closing time is controlled by the design of the delay groove 2032, so that the purpose of controlling the flushing water quantity is achieved. The toilet bowl realizes the distribution of flushing water according to needs, focuses the flushing water and focuses the flushing kinetic energy of the flushing water through the principle of delayed closing, achieves strong flushing, achieves super water saving, and further solves the problems of weak water outlet and difficult pollution discharge of the toilet bowl.
In a non-flushing state, the movable valve core 204 returns to a specific position, so that the water passing cavity 208 is disconnected from the water inlet cavity 209, the water path is blocked, and the first water outlet 214 or the second water outlet 224 does not discharge water any more, thereby achieving a sealing effect.
In the new flushing structure of the toilet, the flushing mechanism 20 is arranged in the box body 70 of the toilet to replace the water flushing function of the traditional toilet, the flushing mechanism 20 flushes the cleaning surface 140 of the toilet through the second flushing pipe 40, and flushes the sewage discharge passage through the jet orifice 130 of the toilet through the first flushing pipe 30. The two flushing pipes are independent from each other, the first valve body 210 and the second valve body 220 quantitatively distribute the flushing water quantity, and the cleaning surface 140 and the sewage channel 110 are pressurized by flushing water according to the required water quantity, so that flushing and sewage discharging of the toilet are realized. The pressurized flushing water pressure and the difference water supply quantity of the cleaning surface 140 and the sewage discharge channel 110 are provided, the toilet sewage discharge pipeline and the cleaning surface 140 are flushed according to the needs, water is saved, and good flushing and sewage discharge effects can be achieved.
Further, the opening degree of the delay groove 2032 of the first valve body 210 is smaller than the opening degree of the delay groove 2032 of the second valve body 220, so that the ratio of the flush volume of the first flush pipe 30 to the flush volume of the second flush is 8:2 to 9: 1. The distribution of the flushing water quantity of the cleaning surface 140 and the sewage outlet is more reasonable, and the industrial problems that the cleaning surface 140 of the closestool cannot be flushed cleanly, and is blocked and difficult to discharge due to improper distribution of the flushing water quantity are effectively solved. Meanwhile, the sum of the flush water discharged by the first valve body 210 and the second valve body 220 (i.e. the total flush water) can completely meet the national standard of the water consumption of the water-saving toilet.
The traditional toilet jet main flushing channel and the cleaning surface 140 share a channel, and the quantity of water discharged by the drainage valve of the water piece simultaneously flushes the cleaning surface 140 and the pipeline of the toilet through the control of the water piece, so that the following limitations exist: 1. when the flush water quantity is used for flushing the cleaning surface 140 and the flushing pipeline of the toilet, the flush water quantity cannot be reasonably distributed, so that the pollution discharge and flushing of the toilet are difficult; 2. the water quantity discharged by the water discharge valve of the water part simultaneously washes the cleaning surface 140 and the pipeline of the closestool, and the washing pressure is divided, so that the washing kinetic energy is weakened. In addition, due to the unreasonable structure of the traditional closestool, when a user flushes the closestool, dirty water in the excrement cavity easily flows back or overflows to the water distribution holes, and pollution discharge is not easy. In the flushing structure adopted by the toilet of the embodiment, the cleaning surface 140 and the sewage outlet are flushed by two independent water pipes, the flushing pressure is concentrated, the opening degree of the delay groove 2032 of the first valve body 210 is smaller than that of the delay groove 2032 of the second valve body 220, the flushing amount is reasonably quantized, the problem that dirty water in the toilet cavity flows back to the water distribution hole can be solved, and the dirty water and excrement can be effectively and directly discharged out of the sewage outlet; and in the flushing period, the filth is discharged to the sewage discharge passage 110, the cleaning surface 140 is easy to clean, the solid or liquid waste deposited or adhered to the cleaning surface is removed, and then the water is supplemented and sealed to replace the clean water, so that the inside of the toilet can be kept relatively clean.
