As shown in figures 1-4, a feeding bottle with air return function comprises a bottle body 1, wherein a nipple 2 is arranged on the bottle body 1, a suction pipe is arranged in the bottle body 1 and connected with the nipple 2, the suction pipe is of a known structure and extends to the bottom in the bottle body, the suction pipe is used for sucking the nipple, liquid in the bottle body can be sucked out by utilizing the suction pipe in the bottle body, a top air return hole 4 is formed in the nipple 2, the lower part of the top air return hole 4 downwards extends to form a V-shaped piece 5 with a wide upper part and a narrow lower part, a normally closed air return seam is formed in the bottom of the V-shaped piece 5 along the horizontal direction, a side through hole 6 is formed in the upper part of the side wall of the bottle body 1, a side air vent valve 7 is embedded in the side through hole 6, and a capillary seam 8 for air inlet and outlet is formed in the side air vent valve 7. The top air return hole 4 is in a normally closed state, and only when the internal pressure of the bottle body forms negative pressure, so that the external air enters from the top air return hole, and the air return seam of the V-shaped piece is jacked by utilizing the pressure difference, so that the external air enters into the internal part of the bottle body, the pressure balance between the internal part and the external part of the bottle body is maintained, and the normal sucking is ensured. The side vent valve is in a normally open state, and can always keep the air inlet and the air outlet, so that the pressure balance between the inside and the outside of the bottle body can be maintained. The capillary gap of the side vent valve is small, even if the liquid height in the bottle body is higher than the position of the capillary gap, the liquid can not flow out of the capillary gap, and as long as the position of the liquid immersed in the capillary gap is not kept for a long time, the problem that the liquid flows out of the capillary gap can not occur generally. To avoid this problem, a side vent valve may be provided in the upper region of the bottle, above the maximum score line.

In addition, a handle 3 with an integrated structure can be arranged on the bottle body 1, so that the bottle is convenient to hold.

The side vent valve 7 includes an inner seal body 71, an outer seal body 72, and a seal connection portion 73, one end of the seal connection portion 73 is connected to the outer seal body 72 and exposed to the outside of the outer seal body 72, the other end of the seal connection portion 73 is connected to the inner seal body 71, and a capillary slit 8 is provided in the seal connection portion 73, whereby the inside of the bottle 1 is communicated with the outside atmosphere through the seal connection portion 73. The inner sealing body, the outer sealing body and the sealing connecting part are of an integrated structure. The side vent valve is utilized to seal the side through hole of the side wall of the bottle body, the capillary gap is kept in a normally open state, external air can enter the bottle body from the capillary gap, and gas in the bottle body can flow out of the bottle body through the capillary gap, so that the gas can flow in and out of the same capillary gap.

A clamping groove 74 is arranged between the outer sealing body 72 and the inner sealing body 71, and the side wall of the side through hole 6 on the bottle body 1 is clamped in the clamping groove 74 to form a tight fit. The side vent valve is made of food-grade silica gel material, so that the safety is high.

The part of the inner sealing body stretches into the bottle body, a groove cavity is formed in the inner sealing body, the capillary gap is communicated with the groove cavity, and the part of the inner sealing body stretches into the bottle body, so that the inner sealing body can play a role in blocking liquid from entering the groove cavity to a certain extent.

The outer side wall of the bottle body 1 is provided with a groove position 9, the side through hole 6 is positioned in the groove position 9, and the outer sealing body 72 is attached to the surface of the groove position 9. After the outer sealing body 72 is assembled in the groove position 9, the outer surface of the outer sealing body 72 is flush with the outer surface of the bottle body 1, so that the overall structure is more compact, and the original appearance of the bottle body is not affected.

In addition, the nipple 2 is provided with two top air return holes 4 which are symmetrically distributed on two sides of the center of the nipple, so that the nipple is ensured to have sufficient air return function.
