[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0025] Embodiment one, by Figures 1-6As shown, this utility model includes a base 1, a valve body 2, a valve head 3, a flexible membrane 4, a self-sealing diaphragm 5, an inner cavity 6, and a valve core air guide cavity 7. The upper end of the base 1 is connected to the valve body 2, and the upper end of the valve body 2 is connected to the valve head 3. Flexible membranes 4 are connected to both sides of the upper middle part of the valve head 3. The top of the flexible membranes 4 on both sides is connected to the self-sealing diaphragm 5. An inner cavity 6 is formed between the inner sides of the flexible membranes 4 on both sides. A valve core air guide cavity 7 is opened inside the valve body 2, and the inner cavity 6 communicates with the valve core air guide cavity 7.

[0026] The base 1, valve body 2, valve head 3, flexible membrane 4 and self-closing diaphragm 5 are integrally molded, and the base 1, valve body 2, valve head 3, flexible membrane 4 and self-closing diaphragm 5 are made of silicone material.

[0027] The valve head 3 is designed in the shape of a garlic clove, with a wide bottom and a narrow top, forming a gradual pressure dispersion gradient.

[0028] The valve tip formed by the valve core air guide chamber 7 and the flexible membranes 4 on both sides has an angle of 15°-25°; the airflow is guided to rotate and rise along the cut, and cooperates with the expansion of the flexible membranes 4 on both sides to automatically open and close the flexible membranes 4 on both sides under a pressure difference of 5-15kPa, matching the infant's sucking frequency (0.5-1.5Hz).

[0029] Working principle:

[0030] The return valve of this device is injection molded from silicone material. The central valve core structure is garlic-shaped, and the valve tip is equipped with a self-closing diaphragm 5.

[0031] The flexible membranes 4 on both sides form an adaptive membrane layer that can expand or contract to withstand pressure changes;

[0032] The garlic-shaped design, wide at the bottom and narrow at the top, creates a gradual pressure distribution gradient, while the streamlined outline guides the liquid to flow smoothly. Figure 6 As shown, this reduces turbulence and vortex generation, thereby reducing the impact of dynamic pressure on the valve core. When subjected to liquid impact pressure, it quickly guides the liquid to diffuse around the bottom of the bottle, and the flexible membranes 4 on both sides of the valve core tighten to seal the valve tip and prevent leakage.
