[0039] See also Figures 1 to 6 As shown, the utility model provides a low-cost push button control mechanism 100, and the push button control mechanism 100 includes a switching column 1 and a push button assembly 2;

[0040] The switching column 1 has a horizontal main section 11 and an extended operating section 12, and the push button assembly 2 is connected to the extended operating section 12. When in use, the horizontal main section 11 can be driven to move horizontally by operating the push button assembly 2;

[0041] The horizontal main section 11 is provided with a gear pin 13 at one end close to the extended operating section 12, so as to realize the gear switching by using the gear pin 13; the horizontal main section 11 is provided with a first sealing structure 31, a second sealing structure 32 and a third sealing structure 33 in sequence from the free end to the gear pin 13, a water blocking segment 14 is formed between the first sealing structure 31 and the second sealing structure 32, and a water passing segment 15 is formed between the second sealing structure 32 and the third sealing structure 33; when the push button control mechanism 100 is working, the push button assembly 2 is pushed to drive the gear pin 13 to switch the gear, so as to drive the first sealing structure 31, the second sealing structure 32 and the third sealing structure 33 to move linearly to realize water outlet control.

[0042] The utility model designs a push button control mechanism 100 including a switching column 1 and a push button assembly 2. The switching column 1 has a horizontal main section 11 and an extended operating section 12. The horizontal main section 11 is provided with a shift pin 13 at one end close to the extended operating section 12, and a plurality of sealing structures are arranged at intervals on the horizontal main section 11. At the same time, the push button assembly 2 is connected to the extended operating section 12. When in use, it is only necessary to operate the push button assembly 2 to drive the plurality of sealing structures on the horizontal main section 11 to move horizontally and linearly to achieve water outlet control. Compared with the existing water outlet control mechanism, the push button control mechanism of the utility model has a simpler overall structure, is easier to operate, and has a lower production cost. At the same time, the first sealing structure 31 and the second sealing structure 32 can cooperate to achieve the water outlet pause function, and the function is more abundant.

[0043] In some embodiments of the present invention, please refer to Figure 2 and Figure 5 As shown, the first sealing structure 31, the second sealing structure 32 and the third sealing structure 33 all include a sealing groove 111 formed on the horizontal main section 11 and a sealing ring 4 sleeved on the sealing groove 111, wherein the sealing ring 4 can be a rubber sealing ring;

When the push button control mechanism 100 of the utility model is used, the horizontal main body section 11 of the switching column 1 needs to be movably inserted into a switching cylinder 5, and the outer ring 42 of the sealing ring 4 is pressed against the inner wall of the switching cylinder 5.

[0045] The utility model designs one side of the sealing ring 4 with an inner ring 41 and a gradually expanding outer ring 42, and the inner ring 41 is tightly sleeved on the sealing groove 111. Since the outer ring 42 of the sealing ring 4 gradually expands, the entire sealing ring 4 has a frustum-shaped structure. When subjected to water pressure, the outer ring 42 of the sealing ring 4 can expand and press against the inner wall of the switching cylinder 5, so that a good sealing effect can be achieved.

[0046] In some embodiments of the utility model, two convex rings 112 are provided on the horizontal main body section 11 at positions corresponding to the first sealing structure 31, the second sealing structure 32 and the third sealing structure 33, and the sealing groove 111 is formed between the two convex rings 112; in the first sealing structure 31 and the second sealing structure 32, the height of the two convex rings 112 at both ends of the water blocking segment 14 is less than the height of the other two convex rings 112. Since in the first sealing structure 31 and the second sealing structure 32, the sealing ring 4 is provided with an inner ring 41 and a gradually expanding outer ring 42 on the side facing the water blocking segment 14, the height of the two convex rings 112 at both ends of the water blocking segment 14 is designed to be less than the height of the other two convex rings 112, which is conducive to the water pressure to better act on the outer ring 42 of the sealing ring 4, so that the outer ring 42 of the sealing ring 4 expands to achieve a better sealing effect.

[0047] In some embodiments of the utility model, a clearance through hole 113 is provided through the horizontal main body section 11 at a position corresponding to the shift pin 13, the upper end of the shift pin 13 is connected to the hole wall of the clearance through hole 113, and the lower end of the shift pin 13 extends to the bottom of the horizontal main body section 11. The utility model provides a clearance through hole 113 through the horizontal main body section 11, and connects the upper end of the shift pin 13 to the hole wall of the clearance through hole 113, so that in actual use, the clearance through hole 113 can play a good role in giving way to the shift pin 13, ensuring that the shift pin 13 can better produce elastic deformation during the switching process, thereby ensuring the smoothness of the switching.

[0048] More specifically, a plane 114 is formed at the bottom of the horizontal main section 11. Since the lower end of the shift pin 13 needs to extend below the bottom of the horizontal main section 11, the utility model forms the plane 114 at the bottom of the horizontal main section 11, so that the lower end of the shift pin 13 will not be restricted, thereby ensuring that the shift pin 13 can complete the switching process more smoothly.

[0049] More specifically, the horizontal main body section 11 is provided with assembly positioning blocks 115 on both sides corresponding to the shift pin 13. The utility model provides the assembly positioning blocks 115 on both sides corresponding to the shift pin 13 on the horizontal main body section 11, so that when the horizontal main body section 11 is movably assembled into the switching cylinder 5, the assembly positioning blocks 115 can be used to position the horizontal main body section 11, ensuring that during use, the horizontal main body section 11 of the switching column 1 can only move horizontally and linearly, and cannot rotate, thereby improving the stability of use.

[0051] In some embodiments of the present invention, the extended operating section 12 is tilted upward along the horizontal direction. Since the push button control mechanism 100 of the present invention is mainly used in the water outlet switching structure of the shower, and the water outlet part and the hand-held part of the shower form a certain angle, the extended operating section 12 is tilted upward along the horizontal direction, so that the structure of the shower can be better adapted, and the push button assembly 2 can be installed on the hand-held part of the shower.

As a specific embodiment of the present invention, the extension operation section 12 is provided with two plug holes 121, and the connecting plate 22 is correspondingly provided with two plug pins 221.

[0053] In some embodiments of the utility model, the push button control mechanism 100 also includes a switching cylinder 5; the side wall of the switching cylinder 5 is provided with a first water outlet 51, a second water outlet 52 and a water inlet 53, and the water inlet 53 is located between the first water outlet 51 and the second water outlet 52; the horizontal main body section 11 of the switching column 1 is movably inserted in the switching cylinder 5, and the inner wall of the switching cylinder 5 is provided with three gear holes 54 along the horizontal direction that cooperate with the gear pin 13.
