Description

A wearable breast pump Technical Field

[0001] The utility model relates to the technical field of maternal and infant electrical appliances, in particular to a wearable breast pump. Background Art

[0002] A breast pump is an electrical device used by mothers to extract breast milk. It stimulates the areola through negative pressure, drawing out milk that has accumulated in the mammary glands. With the advancement of modern science, the importance of breastfeeding in promoting the healthy development of infants is irreplaceable. Breast milk is the safest and most complete natural food for infants.

[0003] Existing electric breast pumps are divided into portable and wearable types based on product structure.

[0004] Chinese utility model patent CN218961433U discloses a wearable breast pump, comprising a housing, a tee and a feeding bottle, wherein the tee is disposed within the housing; the feeding bottle is snap-fitted to the housing; the feeding bottle comprises a milk storage bottle, a one-way valve and a feeding bottle cap; the feeding bottle cap is provided with a through hole for securing the one-way valve; the feeding bottle cap is detachably secured to the opening of the milk storage bottle; the one-way valve is detachably secured to the feeding bottle cap; a milk outlet of the one-way valve extends through the through hole into the interior of the milk storage bottle; an opening is provided at the lower end of the housing; the one-way valve is connected to the tee through the opening; and the tee is in communication with the interior of the feeding bottle.

[0005] It can be seen that the shortcomings of the existing technology are: (1) The wearable breast pumps disclosed generally adopt an independent milk storage bottle structure, that is, the milk storage bottle is connected to the three-way component, and the three-way component is buckled to the main unit. The theoretical height of such a structure is at least the sum of the heights of the milk storage bottle and the main unit. Therefore, the structure of the wearable breast pump is relatively bloated and bulky; (2) A one-way valve structure is generally used. If the milk flow rate is very small, the pressure on the one-way valve is insufficient, which will affect the opening of the one-way valve. If the breast pump is not used for a long time, the valve plate of the one-way valve will age and become stiff, and it needs to be replaced in time. Utility Model

[0006] The present invention provides a wearable breast pump. Compared with existing wearable breast pumps, the present invention not only optimizes the structure of existing wearable breast pumps, achieving a more compact and compact overall structure, but also eliminates the need for a one-way valve, thus avoiding the drawbacks associated with using one-way valves.

[0007] To achieve the above purpose, this utility model patent adopts the following technical solutions:

[0008] A wearable breast pump comprises a trumpet-shaped breast shield and a three-way component, a diaphragm seat, a milk bowl, an air bag and a main unit; the trumpet edge of the breast shield extends outward to form an annular fitting edge, the rear end of the breast shield has an opening, and a latch extends outward from the opening; the trumpet edge of the three-way component extends outward to form a raised annular positioning ring, and the annular fitting edge of the breast shield is snapped into the raised positioning ring of the three-way component; the latch at the rear end of the breast shield can be connected to the rear end of the three-way component, and the rear end of the three-way component is also provided with a milk outlet and an air inlet.

[0009] The diaphragm seat is composed of a diaphragm sheet, a positioning column and a connecting piece. The diaphragm sheet is attached to the milk outlet of the three-way component when no negative pressure is applied; the positioning column is a hollow column, which can be a cylinder or a cube, etc. The positioning column is inserted into the air outlet of the three-way component; the connecting piece connects the isolation sheet and the positioning column to form a whole.

[0010] The milk bowl is connected with the three-way component, the diaphragm seat and the breast shield. The milk bowl is provided with a cavity for accommodating an air bag and a cavity for accommodating milk. The milk bowl has a through hole, which is connected to the cavity for accommodating the air bag outward and extends a section of trachea inward; the trachea is inserted into the cavity of the diaphragm seat positioning column.

[0011] The air bag is in a cylindrical shape, and a protruding annular positioning ring is extended outward from the edge and buckled into the cavity of the milk bowl for accommodating the air bag.

[0012] The host at least includes a power module, an MCU control module and a vacuum pump.

[0013] Beneficial effects: The utility model provides a wearable breast pump, which can not only optimize the structure of the existing wearable breast pump and achieve a more compact structure, but also achieve the compactness of the structure mainly through the following aspects: first, it does not use the one-way valve or duckbill valve structure in the prior art; second, it does not use an independent milk storage bottle as a liquid storage structure, but places the milk storage cavity in the milk bowl, and the milk bowl actually becomes a comprehensive functional body; third, through the flexible breast shield structure, during the milking process, the breast shield can produce deformation to squeeze the breast areola and stimulate lactation.

[0014] The wearable breast pump of this invention does not require a one-way valve, thus avoiding the drawbacks of using a one-way valve structure. Since the milk storage cavity is placed in the milk bowl, it does not adopt the conventional structure of stacking a main unit and a separate milk bottle, thus achieving a more compact structure and a small size.
