[0079] The working principle of the first flushing mechanism 3 is as follows: the pressing unit 3.1 is pressed, the driving end of the first connecting rod 4.3 goes down, thereby driving the other end of the first connecting rod 4.3 to lift the second connecting rod 4.4, the protrusions 4.7 on the first connecting rod 4.3 drive the transmission part 2.21 and the valve rod 2.2 to lift, thereby realizing the opening of the flushing port, and in this process, the protrusions 4.7 on the second connecting rod 4.4 pass through the second clearance position 5.16 without interfering with the lifting part 5.11.

[0080] As a further embodiment of the foot control assembly 6, the foot control assembly 6 comprises a mounting part 6.1 arranged in the main body 1, and a foot control part 6.2 extending out of the main body 1, the foot control part 6.2 being used to be interactively obtained with a stroke, the first control end 5.3 being connected with the foot control part 6.2, and the sealing assembly 7 being further arranged between the water tank 1.1 and the main body 1, the traction rope 5.2 being arranged through the sealing assembly 7 and being connected with the foot control assembly 6 and the valve rod 2.2.

[0081] As Figure 15As shown, in the present embodiment, the traction rope 5.2 forms a stretching section 5.23 between the mounting portion 6.1 and the sealing assembly 7, and forms a lifting section 5.24 between the sealing assembly 7 and the valve rod 2.2, both the stretching section 5.23 and the lifting section 5.24 are arranged in a winding manner, the first control end 5.3 is formed on the stretching section 5.23 to be pressed by the foot control portion 6.2, and the second control end 5.4 is formed on the lifting section 5.24 to be arched upward due to the stretching stroke of the stretching section 5.23, thereby driving the lifting block 5.1 to move upward.

[0082] By accommodating the mounting portion 6.1 of the foot control assembly 6 in the main body 1, and extending the operated foot control portion 6.2 outside the main body 1, and arranging the traction rope 5.2 inside the main body 1 and the water tank 1.1, the space optimization of the foot control flushing mechanism is realized, and the area planning of different scenes is facilitated.

[0083] As a further explanation of the traction rope 5.2,

[0084] The traction rope 5.2 includes a sleeve 5.21 and a pull wire 5.22 arranged in the sleeve 5.21, one end of the sleeve 5.21 is fixed as a fixed end with the valve body 2.1, the first control end 5.3 is formed at the other end of the sleeve 5.21 and connected with the foot control portion 6.2, one end of the pull wire 5.22 is fixed as a fixed end with the mounting portion 6.1, and the second control end 5.4 is formed at the other end of the pull wire 5.22 and connected with the lifting block 5.1.

[0085] As shown, Figure 10 and Figure 13 Specifically, the first control end 5.3 and the pull wire fixed end 5.26 form a first active section 5.5, the second control end 5.4 and the sleeve fixed end 5.25 form a second active section 5.6, the first active section 5.5 and the second active section 5.6 are arranged in an inverse ratio, wherein the length of the pull wire 5.22 is greater than the length of the sleeve 5.21, and the lifting stroke of the lifting block 5.1 matches the difference between the lengths of the sleeve 5.21 and the pull wire 5.22, and the length change caused by the action of the lifting block 5.1 is wound and released in the first active section 5.5 and the second active section 5.6.

[0086] The stretching section 5.23 is inserted into the water tank 1.1 from bottom to top, and the lifting section 5.24 extends from the sealing assembly 7 to above the valve assembly 2 and is connected with the valve rod 2.2 from top to bottom, so that the pull wire 5.22 and the sleeve 5.21 in the water tank 1.1 are arranged in a U-shaped manner or a U-shaped winding manner.

[0087] As shown, Figures 1 to 3As shown, further, in order to enable the lifting block 5.1 to return to the water closing position after the flushing action is completed, a tension spring 5.7 is further arranged between the lifting block 5.1 and the valve body 2.1.

[0088] As an option, the bottom of the lifting block 5.1 is provided with an upper hook ring for connecting the upper end of the tension spring 5.7, and the valve body 2.1 is provided with a lower hook ring for connecting the lower end of the tension spring 5.7.

[0089] As a preferred, the valve body 2.1 is further provided with a mounting groove 2.12 for arranging the tension spring 5.7 therein, so that the tension spring 5.7 has a portion accommodated in the mounting groove 2.12 at any vertical position of the lifting block 5.1, thereby ensuring the stability of the returning force of the lifting block 5.1.

[0090] Working principle of the second flushing mechanism 5:

[0091] In the normal state, the valve rod 2.2 is located at the relatively lower position of the valve body 2.1, so that the valve rod 2.2 is closed with the flushing port, the second control end 5.4 is away from the fixed end of the sleeve 5.21, at this time the second movable section 5.6 has the maximum length, and the first control end 5.3 is close to the fixed end of the pull wire 5.22, at this time the first movable section 5.5 has the minimum length.

[0092] In the operation process:

[0093] For the traction rope 5.2, the stretching section 5.23 is pressed towards the lifting section 5.24 under the action of the foot control part 6.2, and part of the sleeve 5.21 enters the water tank 1.1 under the action of the pressing force, and the lifting section 5.24 has a tendency to lift upwards after obtaining the pressing length,

[0094] For the sleeve 5.21, since the fixed end of the sleeve 5.21 is fixed on the valve body 2.1, the lifting section 5.24 is forced to arch, and the two sides of the winding position on the lifting section 5.24 have a tendency to straighten;

[0095] For the pull wire 5.22, since the fixed end of the pull wire 5.22 is fixed on the mounting part 6.1, the second control end 5.4 obtains the upward straightening force under the arching tendency of the sleeve 5.21, thereby driving the valve rod 2.2 to lift through the lifting block 5.1, and realizing the opening of the flushing port.

[0096] At this time, the valve stem 2.2 is lifted by the pull wire 5.22 under the above action, so that the valve stem 2.2 is close to the fixed end of the sleeve 5.21, thereby reducing the length of the second movable section 5.6. Meanwhile, the first control end 5.3 is moved away from the fixed end of the pull wire 5.22 under the action of the foot control part 6.2, and the length of the first movable section 5.5 increases with the action of the sleeve 5.21, so that the pull wire 5.22 can be released in the first movable section 5.5, thereby obtaining the space to bend, so that the pull wire 5.22 bends away from the valve stem 2.2 in the first movable section 5.5 and drives the valve stem 2.2 away from the flush port.

[0097] During the reset process: the lifting block 5.1 returns to its original position under the action of the tension spring 5.7, and the second control end 5.4 descends with the valve stem 2.2;

[0098] For the traction rope 5.2, the arched section of the lifting section 5.24 is released and falls during operation, while the fixed end of the sleeve 5.21 on the lifting section 5.24 is fixed, and the fixed end of the pull line 5.22 is fixed on the installation part 6.1, which forces the free end of the sleeve 5.21 on the tension section 5.23 to relax.

[0099] For sleeve 5.21 and pull wire 5.22, the valve stem 2.2 moves away from the fixed end of sleeve 5.21 to increase the length of the second movable segment 5.6. At this time, the first control end 5.3 is forced to move toward the fixed end of pull wire 5.22 to reduce the length of the first movable segment 5.5, so that the part of pull wire 5.22 that is bent on the first movable segment 5.5 is forced to straighten and is released on the second movable segment 5.6, realizing the return of foot control assembly 6 and valve assembly 2.

[0100] like Figure 7 As shown, in some other embodiments, in order to achieve synchronous transmission between the second control terminal 5.4 and the lifting block, the lifting block 5.1 is provided with a cavity 5.12 for limiting the current position of the pull wire 5.22. The cavity 5.12 is provided with at least one limiting clip 5.17. The pull wire 5.22 is arranged in the limiting clip, and the pull wire 5.22 extends out of the cavity 5.12 in an adjustable manner.

[0101] Preferably, a fixed end 5.41 is formed on the second control end, and a groove for inserting a pull wire is provided in the limiting card, and the fixed end abuts against the end face of the limiting card in the lifting direction.

[0102] Furthermore, there are two limiting clips inside the cavity, and the two limiting clips are arranged in the same direction about the lifting direction. Two fixed ends are formed on the second control end. With this arrangement, the fixed ends can be selectively abutted against the end face of one limiting clip or the other limiting clip, thereby realizing the stroke adjustment of the second control end.

[0103] Further, the number of the limiting clamping pieces in the cavity is three, the three limiting clamping pieces are arranged in the same direction about the lifting direction, two fixed end portions are formed on the second control end, and the fixed end portion 5.41 can be abutted on the end face of one limiting clamping piece or another limiting clamping piece, so that the stroke adjustment range of the second control end is improved.
