The structure of the self-resetting flush valve button 100 of the present invention is as shown in FIGS. 1-4, and includes a first guiding seat 1, an active pushing block 2, a first spring 3, a second guiding seat 4, a passive pushing block 5 and a second. Spring 6. The first guiding seat 1 is provided with a first guiding slot 11 , and the second guiding seat 4 is provided with a second guiding slot 45 . When the active pushing block 2 slides along the second guiding slot 45 , the passive pushing block 5 is simultaneously pushed The two guide grooves 45 are moved. When the passive push block 5 is pushed out of the second guide groove 45, the second spring 6 is reversely reset. At this time, the passive push block 5 is rotated by 0 degrees in total, and enters another adjacent one. In the two guide grooves 45, the active push block 2 is misaligned and avoided, and the reset is smoothly performed; and after the external force is released, the active push block 2 returns to the original path along the second guide groove 45 under the action of the first spring 3, and enters In the first guiding groove 11, under the action of the guiding inclined surface, the active pushing block 2 rotates 0/2 degrees into the adjacent other first guiding groove 11, so that the active pushing block 2 is just right when the pressing button is pressed next time. It is in the same guide groove as the passive push block 5.

The details are as follows - the first guide seat 1, the cylindrical structure, the inside of which is provided with the accommodating space 10, and a plurality of first guide grooves 11, which are disposed uniformly on the circumference of the cylindrical inner wall, are six in the present embodiment. A guide slope 12 is defined on the side wall of the opening of the first guide groove 11, and an opening 13 is defined in the top of the first guide seat 1.

The active push block 2 includes a cylindrical main body portion 22 and a plurality of upper guide posts 21 extending from the main body portion 22 and uniformly disposed along the circumference. The number of the upper guide posts 21 should be half of the number of the first guide grooves 11, In the present embodiment, there are three. The main body portion 22 can be received in the accommodating space 10 of the first guide seat 1 and protrudes from the opening 13 for the user to press. The lower end of the upper guide post 21 is provided with an outwardly protruding protrusion 210. The protrusion 210 can cooperate with the first guiding groove 11. The first guiding surface 211 and the second guiding surface are disposed on the protruding block 210. 212.

The first spring 3 has one end abutting against the active push block 2 and the other end abutting against the second guide seat 4. In the embodiment, the bottom of the active push block 2 is provided with a receiving cavity 23 for partially accommodating the first spring 3.

The second guiding seat 4 has a cylindrical shape, and the inner wall is provided with a plurality of guiding blocks 40 which are evenly arranged along the circumference, and a second guiding groove 45 is formed between the guiding blocks 40. The number of the second guide grooves 45 is the same as that of the first guide grooves 11, and is also six in the present embodiment. among them The guiding block 40 is provided with an upper guiding surface 41, a lower guiding surface 42 and a blocking block 43. The upper guiding surface 41 is a sloped surface that can cooperate with the first guiding surface 211 of the active pushing block 2, and the lower guiding surface 42 is also a sloped surface. The blocking block 43 is for abutting against the other end of the first spring 3.

The passive push block 5 includes a cylindrical mandrel portion 52 and a plurality of lower guide posts 51 projecting from the mandrel portion. The lower guide columns 51 are arranged along the circumference, and the number thereof is the same as the number of the upper guide columns 21, and is also three in the present embodiment. The top of each lower guide post 51 is provided with a third guiding surface 510 which can cooperate with the first guiding surface 211 of the upper guiding post and the lower guiding surface 42 of the second guiding seat.

The second spring 6 abuts against the bottom of the passive push block 5, and the other end can be abutted against other parts of the mechanism to be restrained.

The self-resetting flush valve button 100 of the present invention can be mounted in the flush valve 200 (shown in Figure 16).

In another embodiment of the self-resetting flush valve button 100 of the present invention, the first spring 3 and the second spring 6 may be a spring mechanism or other elastic members.

In still another embodiment of the self-resetting flush valve button 100 of the present invention, the second spring 6 configuration may not be provided, but the reset function may be realized only by the water pressure of the flush valve 200.

The working process of the present invention will be described below with reference to Figs.

In the initial state, as shown in Fig. 9, the upper guide post 21 of the active push block 2 is housed in the first guide groove 11 of the first guide seat 1 at intervals. The head of the main pusher 2 is extended from the upper surface of the first guide seat 1. The lower guide post 51 of the passive push block 5 is received in the second guide groove 45 of the second guide seat 4 at intervals. When the head of the active push block 2 is pressed, the active push block 2 is moved downward, and the first spring 3 is pressed. After the first guiding surface 211 of the active pushing block rotates 30 degrees along the upper guiding surface 41 of the second guiding seat 4, as shown in FIG. 10, it slides into the second guiding groove 45 of the second guiding seat 4, just right. The upper guide post 21 of the active push block abuts the lower guide post 51 located in the second guide groove 45, wherein the first guiding surface 211 of the upper guide post 21 is in contact with the third guiding surface 510 of the lower guiding post 51 , as shown in Figure 11. The active push block 2 is further moved downward, and under the action of the lower pressure and the restriction of the second guide groove 45, the passive push block 5 moves downward, and the second spring 6 is pressed.

During the pressing process, the passive push block 5 touches the flush valve at the lower end, so that the flush valve starts to flush. When the lower guide post 51 of the passive push block 5 is about to be disengaged from the second guide groove 45, since the first guiding surface 211 of the active push block 2 applies an oblique thrust to the third guiding surface 510 of the passive push block 5, The passive push block 5 is rotated, as shown in Fig. 12. When rotated by 30 degrees, the second spring 6 is pressed to generate an upward elastic force, causing the passive push block 5 to move upward. Since the third guiding surface 510 of the passive pushing block 5 is in contact with the lower guiding surface 42 of the guiding block 40 at this time, as shown in FIG. 13, under the action of the guiding surface 510, the passive pushing block 5 is under the action. The guide post 51 is again rotated by 30 degrees and then enters the adjacent second guide groove 45. Thus, the passive push block 5 is rotated 60 degrees and then returned to the initial position, as shown in Fig. 14, thereby completing the flushing action. The active push block 2 is stopped, and the active push block 2 moves upward due to the elastic force of the first spring 3. At this time, the second guiding surface 212 on the upper guiding post 21 is in contact with the guiding inclined surface 12 of the first guiding seat 1. Under the guiding action, the active pushing block 2 is rotated by 30 degrees and then enters into the adjacent first guiding slot 11 , return to the original location, as shown in Figure 15.

In this way, the passive push block 5 is not blocked by the active push block 2, and even if the active push block 2 is not reset, the passive push block 5 can be quickly reset, so that the flush valve is closed. This enables a quantitative water supply to solve the unnecessary water waste in the prior art due to pressing the button for a long time.

Obviously, the number of the upper guide post, the lower guide post, and the first guide groove and the second guide groove is not necessarily three or six, and may be two or four, or four and eight, and the like. .

The button of the present invention can be used in a manual or automatic flush valve.
