Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, and in particular to a breast pump. Background Technology

[0002] A breast pump is a tool used to express breast milk that has accumulated in the mammary glands. It uses an internal vacuum negative pressure pump to change the internal air pressure, which is a cycle of "sucking" and "releasing" to mimic the action of a baby sucking breast milk and achieve the purpose of milk expression.

[0003] As modern women have children and are no longer confined to breastfeeding at home, portable breast pumps are becoming increasingly popular. Therefore, a breast pump that is portable, easy to clean, and aesthetically pleasing is better suited to meet the needs of breastfeeding mothers. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the prior art, this utility model provides a breast pump with a practical structure that is easy to promote.

[0005] A breast pump includes a breast shield, a funnel-shaped nozzle, and a main unit;

[0006] The breast collection shield and the flared mouth are fastened together and fixed. The top of the breast collection shield is provided with a compartment. The outer shell is fastened to the compartment. The main unit is installed inside the compartment. The main unit includes an air pump and a solenoid valve. The air pump is connected to the suction bowl through an air pipe. The breast collection shield is provided with a channel. The suction bowl is connected to the channel of the breast collection shield.

[0007] The horn-shaped opening is a suction cup, and a second channel is provided in the middle of the horn-shaped opening. A duckbill valve is connected between the second channel and the first channel.

[0008] Preferably, the first channel is located at the top of the breast cup, and the suction bowl is installed on the first channel; a three-way connector is installed between the breast cup and the flared opening, one end of the three-way connector is connected to the suction bowl on the first channel, and the other end is connected to the second and third channels, which are connected to the duckbill valve.

[0009] Preferably, the breast cup has an interface inside, and the interface has an arc-shaped notch for fixing the tee connector, and the size of the arc-shaped notch is different.

[0010] Preferably, the breast cup and the flared opening are provided with a milk outlet.

[0011] Preferably, a sealing silicone gasket is installed at the connection of the suction bowl.

[0012] The beneficial effects of this utility model are as follows:

[0013] This new type of breast pump uses an internal air pump to generate negative pressure, which is then drawn in by the suction bowl to achieve the function of milk expression. The flared nozzle fits tightly against the breast to complete the milk expression action. The fixed position of the flared nozzle makes it easy to disassemble and clean. The overall structure is reasonably designed, has good sealing performance to prevent air leakage, and is convenient and portable to use. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] In the description of the embodiments of this utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] As attached Figure 1-5 As shown, a breast pump includes a breast cup 100, a flared mouth 200, and a main unit 300;

[0027] The breast collection shield 100 and the flared mouth 200 are fastened together. The top of the breast collection shield 100 is provided with a container, and a housing 301 is fastened to the outside of the container. The main unit 300 is installed inside the container. The main unit 300 includes an air pump and a solenoid valve. The air pump is connected to the suction bowl 303 through the air pipe 302. The breast collection shield 100 is provided with a channel 101, and the suction bowl 303 is connected to the channel 101 of the breast collection shield 100. The breast collection shield 100 and the flared mouth 200 are provided with milk outlets 204.

[0028] The flared mouth 200 is in the shape of a suction cup, and a second channel 201 is provided in the middle of the flared mouth 200. A duckbill valve 202 is connected between the second channel 201 and the first channel 101.

[0029] Channel 101 is located at the top of breast cup 100, and suction cup 303 is installed on channel 101. A three-way connector 203 is installed between breast cup 100 and flared opening 200. One end of the three-way connector 203 is connected to suction cup 303 on channel 101, the other end is connected to channel 201, and the third end is connected to duckbill valve 202. A sealing silicone gasket is installed at the connection of suction cup 303.
