Abstract
Description
Wearable breast pump and three-way component thereof
[0001] Technical Field
[0002] The utility model belongs to the technical field of maternal and infant electronic products, and particularly relates to a wearable breast pump and a three-way component thereof. Background Art
[0003] Wearable breast pumps are widely popular among breastfeeding women, especially working women. Wearable breast pumps generally consist of a main unit and a pump assembly. These can be categorized into two main types based on the pump assembly's structure: pumps with a bottle that collects milk, and pumps with a bowl that collects milk. Generally speaking, a pump assembly with a bowl consists of a bowl that collects milk, a breast shield that snaps onto the bowl, an air bag, and a duckbill valve or a valve seat with a valve disc.
[0004] Chinese invention patent CN103212123B discloses a breast pump with a matching breast milk reservoir. The present 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 expressed 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.
[0005] Chinese utility model patent CN219148734U discloses a new type of breast pump to solve the technical problem that the duckbill valve causes the overall volume of the breast pump to be large. The invention comprises 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 comprises a positioning groove arranged on the milk bowl and a mouth arranged on the main unit and inserted into the positioning groove. The buckle structure comprises a first buckle element arranged on the main unit and a second buckle element arranged on the milk bowl, which are mutually connected. The second buckle element is a second protrusion arranged on the milk bowl. The first buckle element comprises a first protrusion arranged on the main unit. The mouth of the main unit is inserted into the positioning groove of the milk bowl. The first protrusion abuts against the inner side of the second protrusion. Alternatively, the first buckle element comprises a groove arranged on the main unit. The mouth of the main unit is inserted into the positioning groove of the milk bowl, and the second protrusion is embedded in the groove.
[0006] The structural problem with the above-mentioned technical solution is that when milk is discharged into the milk bowl through the valve assembly or valve seat with a valve disc, there is significant resistance, resulting in unsatisfactory milk discharge. Furthermore, the valve assembly or valve seat with a valve disc is more complex and bulky than the duckbill valve. Further improvement is needed. Summary of the Invention
[0007] To overcome the shortcomings of the prior art, the present invention provides a wearable breast pump and its three-way connection. Compared with the prior art, the overall structure of the breast pump is simpler; there is less resistance when the milk is discharged into the milk bowl; and it is also easier to clean.
[0008] In order to achieve the above technical purpose, the technical solution provided by the utility model is:
[0009] The wearable breast pump described in this utility model comprises a main unit with a suction pump, a disc-shaped airbag, a milk cup, a breast shield, and a valve. The main unit with the suction pump has at least one negative pressure outlet. The flat disc-shaped airbag is installed between the milk cup and the main unit and covers the negative pressure outlet. The wearable breast pump also includes a three-way component.
[0010] 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, with a group of symmetrical, outwardly protruding male buckles on the outside of the three-way component, and buckle positions extending outward from the position corresponding to the top edge of the three-way component.
[0011] The negative pressure port is connected to the vent of the milk bowl of the wearable breast pump, and the milk outlet is equipped with a valve sheet.
[0012] 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 with each other and are embedded; 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.
[0013] 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 in the milk bowl.
[0014] The breast pump opening on the three-way component is matched and embedded with one end of the breast pump shield of the wearable breast pump.
[0015] The breast shield is trumpet-shaped, and the other end edge of the breast shield is provided with an inwardly curled edge for fastening and sealing the bowl mouth of the milk bowl.
[0016] The upper end of the milk bowl is provided with a guide groove.
[0017] The beneficial effects of this utility model are as follows: in this technical solution, the three-way component is separated from the milk bowl, and the valve plate is used for milk discharge. Compared with structures using valve seats, the structure is simpler. 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, the simple structure is also more convenient to clean. BRIEF DESCRIPTION OF THE DRAWINGS
