In this embodiment, since the sealing body 21 is an annular sheet structure and has a small thickness, it has a good and easily embodied extension characteristic when being acted by the water pressure in the water outlet chamber, and when being extended, the sealing body 21 can be tightly wrapped on the water inlet surface 311 of the movable member 3, thereby achieving an excellent sealing effect.

The movable piece 3 is connected with the fixed piece 1 through a convex shaft 14, a rotation stopping cap 5 and a screw 6, and the movable piece 3 is suitable for rotating between a first position and a second position relative to the fixed piece 1 besides being axially fixed relative to the fixed piece 1; specifically, the protruding shaft 14 penetrates through the shaft hole 312 of the second partition plate 31, and the diameter of the protruding shaft 14 is slightly smaller than the diameter of the shaft hole 312, so that the movable member 3 can rotate relative to the protruding shaft 14 and the fixed member 1 on the premise that the protruding shaft 14 is positioned to form a coaxial relationship with the fixed member 1; the rotation stopping cap 5 is a tubular structure with an opening at one end, the rotation stopping cap is sleeved at the free end of the protruding shaft 14 and forms rotation stopping fit with the protruding shaft 14 in a polygonal structure, the screw 6 penetrates through the bottom of the rotation stopping cap 5 and forms threaded connection with the protruding shaft 14, when the screw is screwed in place, the rotation stopping cap 5 is axially limited on the free end of the protruding shaft 14, so that an axial limiting space with stable distance is formed between the opening end of the rotation stopping cap 5 and the water outlet surface 211 of the sealing gasket 2, the two side surfaces of the second partition plate 31 are respectively limited by the water outlet surface 211 and the end surface of the opening end of the rotation stopping cap 5, and therefore, the movable piece 3 cannot axially displace relative to the fixed piece 1.

As shown in fig. 8 and 9, in the present embodiment, the outer diameter of the movable member 3 is equal to the outer diameter of the fixed member 1, and after the two are connected in place, the outer wall is in smooth transition, so that a tubular structure with a complete shape is formed between the connected fixed member 1 and the movable member 3, and the sealing gasket 2 is hidden in the two, thereby maximizing the sealing effect. Compared with the prior art in which the movable piece 3 and the fixed piece 1 need to be sleeved and provided with the sealing ring, the switching water outlet structure has a simpler structure, effectively reduces the extension of the radial dimension, and ensures that the switching water outlet structure 10 has a smaller dimension in the radial direction, thereby being beneficial to being applied to water outlet device products (such as feeding bottles, wine bottles and the like with smaller bottle mouths) with higher requirements on the diameter dimension.

In practical operation of the water switching and discharging structure 10 provided in this embodiment, the movable member 3 is driven to rotate, and when the movable member 3 rotates to the first position relative to the stationary member 1 and the sealing gasket 2, the water inlet 3111 on the movable member 3 rotates to be communicated with the water outlet 2111 on the sealing gasket 2 (as shown in fig. 9), so as to switch water to the water discharging structure 10; when the movable member 3 rotates to the second position relative to the stationary member 1, the water inlet 3111 on the movable member 3 rotates to be completely staggered with the water outlet 2111 on the sealing gasket 2, the water inlet 3111 is disconnected from the water outlet 2111 (as shown in fig. 8), and the water outlet structure 10 is switched to be disconnected; in addition, when the movable member 3 rotates between the first position and the second position relative to the fixed member 1, the flow rate of the discharged water can be adjusted according to the communication area of the water inlet 3111 relative to the water outlet 2111.

Preferably, in this embodiment, when the movable member 3 rotates to the second position, the water inlet 3111 on the movable member 3 corresponds to the position of the elastic member 4, that is, when the water inlet 3111 is disconnected from the water outlet 2111, the part of the sealing body 21 acted by the elastic member 4 abuts against the water inlet 3111, so as to play a role of assisting to enhance the sealing effect, and improve the effect of the sealing gasket 2 on sealing the water inlet 3111, and in addition, the elastic member 4 is provided, so that the sealing gasket 2 can still be reliably sealed on the water inlet surface 311 under the conditions of water cut-off and disappearance of water pressure in the water outlet cavity, thereby avoiding the water leakage phenomenon under the water cut-off state.

In the water outlet switching structure 10 of the present invention, the movable member 3 can rotate relative to the stationary member 1, when the movable member 3 rotates to the first position relative to the stationary member 1, the water inlet 3111 is communicated with the water outlet 2111, and the water outlet switching structure 10 is opened to enable water to be discharged; when the movable member 3 rotates to the second position relative to the stationary member 1, the water inlet 3111 and the water outlet 2111 are staggered and disconnected from each other, and at this time, the sealing gasket 2 is pressed against the water inlet surface 311 of the movable member 3 under the action of the water pressure in the water outlet cavity, so that the water cut-off of the water outlet structure 10 is switched.

Because a water outlet cavity is formed between the sealing gasket 2 and the fixed piece 1, the sealing gasket 2 can be reliably attached to and sealed off from the water inlet surface 311 on the movable piece 3 under the action of static pressure in the water outlet cavity in a water-off state, namely, in a state that the water inlet 3111 is disconnected from the water outlet 2111; because the sealing gasket 2 is in an annular structure, the water outlet surface 211 which is used for being matched with the water inlet surface 311 to realize sealing is also in an annular structure, the water inlet surface 311 and the water outlet surface 211 are both in an annular shape, and the sealing area is large, therefore, no matter any point on the water inlet surface 311 or the water outlet surface 211 has a defect in the using process, a reliable sealing main body still exists around the defect, so that the whole sealing performance is not influenced, the sealing effect is reliable, the service life of a product is long, correspondingly, the use cost can be effectively controlled, and the use requirement of a user can be easily met; in addition, because the sealing gasket 2 is matched with the movable member 3 by the concave water outlet surface 211 and the convex water inlet surface 311, and the sealing gasket 2 is of an elastic structure, under the water closing state, the internal part of the sealing gasket 2 has tension due to the isostatic pressure action at one side of the water outlet cavity, and the sealing gasket 2 extends towards the periphery under the guidance of the water inlet surface 311 and is closely matched and attached with the water inlet surface 311, so that the influence of the abrasion defect generated in the using process can be overcome, and the sealing effect is more reliable.
