Description

Technical Field

[0001] The utility model belongs to the technical field of maternal and infant electronic products, and specifically relates to a wearable breast pump and a three-way component thereof. Background Art

[0002] In the prior art, wearable breast pumps are widely welcomed by breastfeeding women, especially working women. Wearable breast pumps are generally composed of a main unit and a milk suction component, which can be divided into two categories according to the structural composition of the milk suction component. One category is a milk suction component with a milk storage bottle, which collects milk through the milk storage bottle; the other category is a milk suction component with a milk storage bowl, which collects milk through the milk storage bowl. Generally speaking, a milk suction component with a milk storage bowl is composed of a milk storage bowl for collecting milk, a breast shield buckled on the milk storage bowl, an air bag and a duckbill valve or a valve seat with a valve sheet.

[0003] Chinese invention patent CN103212123B discloses a breast pump with a matching breast milk reservoir. The invention relates to a breast pump with a matching breast milk reservoir, comprising a breast adapter having a funnel-shaped inlet coupled to a reservoir at one end, wherein when a breast is inserted into the breast adapter, breast milk is squeezed into the reservoir through a unique valve assembly and the milk is stored in the reservoir until the device is removed and the collected milk is emptied into a container.

[0004] In order to solve the technical problem that the duckbill valve causes the overall volume of the breast pump to be large, Chinese utility model patent CN219148734U discloses a new type of breast pump, including a milk bowl and a main unit arranged on the milk bowl, an insertion structure and a buckle structure are provided between the milk bowl and the main unit, the insertion structure includes a positioning groove arranged on the milk bowl and a mouth arranged on the main unit and inserted in the positioning groove, the buckle structure includes a first buckle element arranged on the main unit and a second buckle element arranged on the milk bowl, which are connected to each other, the second buckle element is a second protrusion arranged on the milk bowl, the first buckle element includes a first protrusion arranged on the main unit, the mouth of the main unit is inserted in the positioning groove of the milk bowl, and the first protrusion is abutted against the inner side of the second protrusion, or the first buckle element includes a groove arranged on the main unit, the mouth of the main unit is inserted in the positioning groove of the milk bowl, and the second protrusion is embedded in the groove.

[0005] The problem with the structure of the above technical solution is that when the milk is discharged into the milk bowl through the valve assembly or valve seat with a valve plate, the resistance is large and the milk discharge effect is not ideal. Moreover, the valve assembly or valve seat with a valve plate is more complex in structure than the duckbill valve and is more bulky. It needs to be further improved. Summary of the invention

[0006] In order to overcome the shortcomings of the prior art, the utility model provides a wearable breast pump and a three-way component thereof. Compared with the prior art, the overall structure of the breast pump is simpler; when the milk is discharged into the milk bowl, the resistance is small; and it is more convenient to clean.

[0007] In order to achieve the above technical purpose, the technical solution provided by the utility model is:

[0008] The utility model discloses a wearable breast pump, comprising a main unit with a suction pump, a disc-shaped air bag, a milk bowl, a breast shield, and a valve sheet: the main unit with the suction pump has at least one negative pressure outlet; the disc-shaped air bag is flat, installed between the milk bowl and the main unit, and covers the negative pressure outlet of the main unit. It also includes a three-way component.

[0009] The three-way component is provided with a breast suction port, a negative pressure port and a milk outlet; what is unique is that the three-way component is an elliptical boat-shaped structure, and the outside of the three-way component has a group of symmetrical, outwardly protruding male buckles, and buckle positions extend outwardly at the position corresponding to the top edge of the three-way component.

[0010] The negative pressure port is connected to the vent hole of the milk bowl of the wearable breast pump, and the milk outlet is provided with a valve sheet.

[0011] The inside of the milk bowl is provided with a slot for embedding the three-way component, and the inner edge of the slot is provided with a group of symmetrical, inwardly recessed female buckles; the female buckles and the male buckles of the three-way component cooperate and engage with each other; by squeezing the buckle position of the three-way component, the male buckle of the three-way component can be embedded in the female buckle of the milk bowl.

[0012] The slot in which the three-way component is embedded is provided with a vent hole, and the vent hole directly leads to the area where the saucer-shaped airbag is buckled on the milk bowl.

[0013] The breast suction port on the three-way component is matched and embedded with one end of a breast shield of the wearable breast pump.

[0014] The breast shield is in a trumpet shape, and the other end edge of the breast shield is provided with an inwardly curled edge, which fastens and seals the mouth of the milk bowl.

[0015] The upper end of the milk bowl is provided with a guide groove.

[0016] The beneficial effects of the utility model are as follows: in the technical solution, the three-way component is separated from the milk bowl, and when the valve sheet is used as the milk discharger, the structure is simpler than that of the valve seat. The mold manufacturing is also more reasonable. When the milk is discharged into the milk bowl, the resistance is relatively small. At the same time, due to the simple structure, it is more convenient to clean. BRIEF DESCRIPTION OF THE DRAWINGS
