Description

Milk bowl and breast pump

Technical Field

The invention relates to a milk bowl and a breast pump thereof.

Background technique

The Chinese patent with the authorization announcement number CN205913572U discloses a breast pump head with a milk bowl, which sets the breast pump head inside the milk bowl, maximizes the use of space, simplifies the structure, reduces the cost, and is convenient to use and carry. However, the anti-backsucking device is set outside the milk bowl, and the milk bowl and the anti-backsucking device are connected by a conduit. When the milk bowl and the anti-backsucking device are folded and released separately, the volume is large, and it is still inconvenient to use and fold.

When a component is described as being "connected to" another component, it may be directly connected or connected through a central component. When a component is described as being "provided on another component", it does not mean that the component must be located above or on the upper part of another component, but may be located elsewhere. The terms "left", "right" and similar expressions used herein are merely for the purpose of convenience of explanation.

1 to 4 , the breast pump of the present invention mainly comprises a milk bowl 1 and a suction cup 2, wherein the suction cup is a soft and elastic suction cup, and a detachable cover thereof is arranged at the mouth of the milk bowl, and the suction cup is concave toward one side of the milk bowl so as to fit with the human breast, and a suction hole 3 is arranged at the center of the concave part, and a tee piece is arranged in the milk bowl, and the tee piece and the suction cup are an elastic body integrally formed, so that the first end 41 of the tee piece is integrally connected to the suction hole, and preferably the tee piece and the suction cup are an integrally formed silicone piece, and the second end 42 of the tee piece is integrally or separately connected to a nipple 6 downward, and the second end 42 and the nipple 6 can adopt a connection structure such as plug-in fitting to make the two detachable; an exhaust port 11 is arranged at the top of the milk bowl at the connection position with the suction cup to facilitate exhaust.

In other embodiments, the tee and the suction cup may be split structures, and the tee can be detachably connected to the suction cup. For example, the first end of the tee is plugged into and fitted with the end of the suction hole of the suction cup so that the first end of the tee is connected to the suction hole.

In this embodiment, the outer wall of the milk bowl is provided with an anti-backsucking device 5, and the anti-backsucking device includes a seat body 53 and a cover body 54 that is tightly fitted with the seat body, such as a snap fit. The seat body and the cover body form an air cavity, and an elastic diaphragm 55 is provided in the air cavity to divide the air cavity into two parts; a first vent end 51 is provided on the seat body, and the first vent end is connected to the third end 43 of the three-way piece in an integrated or split manner, and a second vent end 52 is provided on the cover body, and the second vent end forms an air pipe connecting end connected to an external air pipe. In this embodiment, the first vent end is plug-fitted with the third end of the three-way piece. Because the three-way piece is an elastic body integrally formed with the suction cup, it can form a good connection with the first vent end, and the connection between the two has good sealing performance and is not easy to leak.

Among them, the base and the milk bowl are an integral structure formed in one piece, the side or top of the milk bowl has a concave portion, the concave portion forms the base, and the cover and/or elastic diaphragm are detachably connected to the base; in other embodiments, the base and the milk bowl can also be two independent components, the base can be detachably installed on the milk bowl, and the cover and/or elastic diaphragm can be detachably connected to the base.

In this embodiment, the elastic diaphragm is sandwiched between the cover body and the base body. The elastic diaphragm is a diaphragm with a pleated portion. The base body has a surface matching the surface of the pleated portion of the elastic diaphragm. At least the convex portion of the pleated portion is attached to the base body. An air duct 56 is provided between the elastic diaphragm and the base body.

An operating portion for facilitating removal of the cover is provided on the cover or at the edge of the milk bowl. In this embodiment, the operating portion is a groove 12 provided on the edge of the cover of the milk bowl. In other embodiments, the operating portion may also be provided on the cover.

In this embodiment, in order to facilitate the installation of the suction cup, the lower edges of the edges of the suction cup are on the same plane so that the suction cup can be arbitrarily installed on the milk bowl without adjusting the suction cup to a suitable position. The suction cup is made of an elastic elastic material and a circle of buckled edges is provided at the outer end of the suction cup, and a circle of chamfered edges is provided at the outer end of the milk bowl, and the buckled edges are buckled on the chamfered edges. In other embodiments, the milk bowl may also be connected to a pressure ring by threads, and the edge of the suction cup is clamped between the pressure ring and the upper edge of the milk bowl; or, the suction cup is elastic and a circle of buckled edges is provided at the outer end of the suction cup, and a radially retractable hoop is connected to the outer wall of the milk bowl, and the buckled edges of the suction cup are clamped between the hoop and the outer wall of the milk bowl.

In the present embodiment, the milk bowl is a hard milk bowl made of a transparent material, and is provided with a horizontal and/or vertical capacity mark. The side wall of the milk bowl protrudes outward from the bottom of the notch to form the exhaust port. In other embodiments, the milk bowl may also be a soft milk bowl. In other embodiments, the milk bowl may also be a hard milk bowl or a soft milk bowl made of an opaque material.

In this embodiment, the nipple is made of elastic material and its end is flattened, so that a milk outlet gap is formed at the end of the nipple.

When the present invention is used, the air tube is connected to the second ventilation end of the anti-back-sucking device, and then the suction cup is aimed at the breast, and the air tube is connected to the air pump main unit, so that milk can be sucked normally, and the milk flows into the milk bowl from the milk outlet slit of the nipple through the three-way piece. When the milk is sucked, the milk bowl is placed horizontally, and the suction cup together with the three-way piece is removed from the milk bowl, so that the milk can be conveniently taken out, and the anti-back-sucking device can prevent the milk from being sucked into the air pump.

Since the anti-backsucking device is arranged on the outer wall of the milk bowl, the invention is very convenient to use, clean and carry.

The above are only preferred embodiments of the present invention. In addition to the above preferred embodiments, the present invention has other embodiments. Those skilled in the art can make various changes based on the present invention. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined by the claims attached to the present invention.
