Description

Technical Field

[0001] The utility model belongs to the technical field of breast pumps, and in particular relates to a wearable breast pump. Background Art

[0002] A breast pump is used to extract breast milk from the mammary glands. It uses an internal vacuum pump to create pressure fluctuations, creating a cycle of "suction" and "release" that mimics the way a baby sucks milk. To facilitate discreet breastfeeding in public, wearable breast pumps that fit inside a bra have emerged. These pumps consist of a milk storage bowl and a suction bladder. The suction bladder deforms under pressure, allowing the milk to flow into the storage bowl.

[0003] In the prior art, Chinese patent document with publication number CN212262015U discloses a breast pump, comprising a main unit and a three-way assembly, the insertion slot of the main unit being plug-in connected to the insertion portion of the three-way assembly, the three-way assembly comprising a suction cylinder shell and a suction piston installed in the inner cavity of the suction cylinder shell, the suction piston being used to divide the inner cavity of the suction cylinder shell into an internal cavity communicating with a milk suction channel and a suction cavity communicating with a suction pump of the main unit, a vent being provided on the suction cylinder shell, a suction port being provided in the insertion slot of the main unit communicating with the suction pump, a trumpet-shaped sealing ring being provided at the suction port, so that after the three-way assembly is inserted into place, the trumpet-shaped sealing ring can cover the vent and be compressed to fit tightly with the outer surface of the suction cylinder shell. Although this breast pump can effectively solve the problem of poor assembly between the three-way assembly and the main unit of the current breast pump, since the main unit of the breast pump protrudes from the upper part of the milk storage container, this design will cause the main unit to be exposed from the clothes of the user when using the wearable breast pump, which is not concealed enough; in addition, the upper part of the main unit may be squeezed and detached from the milk storage container, causing the main unit to fall and the milk storage container to leak; since the main unit is heavy and the milk storage container is mostly round, the main unit located on the upper part will also cause problems such as unstable placement.

[0004] Therefore, it is very important to design a wearable breast pump that can protect user privacy, prevent the main unit and milk storage container from accidentally falling off, and be placed more stably. Utility Model Content

[0023] Example:

[0024] like Figures 1 to 3As shown, the utility model provides a wearable breast pump, including a main unit and a milk suction module. A accommodating cavity or accommodating groove is provided in the middle position of the main unit for embedding the milk storage module; the main unit and the milk suction module are detachably connected, and the milk suction module includes a breast shield 4 and a milk cup 3; the milk cup is detachably mounted on the breast shield; a milk suction port is provided in the breast shield; a first concave air chamber 14 is provided on the upper part of the milk cup; a second concave air chamber 15 is provided on the upper part of the main unit in a direction corresponding to the first air chamber; a cylinder diaphragm 6 for isolation is provided between the first air chamber and the second air chamber; an air suction device is provided inside the lower part of the main unit; the second air chamber is connected to the air suction device; the first air chamber is communicated with the milk suction port; a one-way valve 5 is also provided in the milk cup, and the milk suction port is connected to the milk cup through the one-way valve; after the main unit extracts the air from the second air chamber through the air suction device, a negative pressure is generated in the first air chamber, so that the milk suction port generates suction, sucks the milk into the milk suction port, and flows into the milk cup.

[0025] The cylinder diaphragm separates the concave portion of the teat cup from the concave portion of the main unit, forming two air chambers. When the vacuum device extracts air from the air chamber inside the main unit and the cylinder diaphragm (the second air chamber), the cylinder diaphragm moves toward the concave portion of the main unit, generating negative pressure (suction) in the air chamber formed outside the cylinder diaphragm and the teat cup (the first air chamber), amplifying the suction force.

[0026] Specifically, such as Figure 2 As shown, the milk suction port is hollow trumpet-shaped; a connecting portion 16 is provided on the milk cup; the connecting portion is inserted into the end of the milk suction port; the connecting portion is connected to the first air chamber and the milk cup respectively.

[0027] In this embodiment, a hollow mounting tube 17 is provided within the milking cup; a one-way valve is fitted onto the mounting tube in an interference fit. Milk entering the milking port is conveyed through the passage and the mounting tube to the one-way valve. Water pressure opens the one-way valve and allows it to flow into the milking cup. During storage, the one-way valve remains closed, preventing backflow.

[0028] Furthermore, the air extraction device includes a circuit board 10, an air pump 7, a solenoid valve 9, and a battery 8. The battery is connected to the air pump and the solenoid valve via the circuit board. The circuit board is used to control the operation of the air pump and the solenoid valve. The air pump and the solenoid valve are both connected to an air pipe 13, and the ends of the connected air pipes extend into the second air chamber. The air extraction device is primarily used to control the extraction of air from the second air chamber.

[0029] like Figure 3 As shown, the main unit comprises a front shell 1 and a rear shell 2, which are joined together by a snap-fit ​​mechanism. A mounting groove is provided along the edge of the rear shell, housing the circuit board, air pump, solenoid valve, and battery. The middle sections of both the front and rear shells are hollow, allowing the milk cup to fit into the main unit and form an encircling connection.

[0030] In addition, a control circuit board 11 is provided on the back shell for controlling key input and light display; the control circuit board adopts an FPC flexible board, which can fit the overall appearance of the breast pump.

[0031] Another example Figure 3 As shown, two positioning balls 12 are further provided on the rear shell; a concave first positioning slot 18 is provided on the milk cup in a direction corresponding to the positioning balls; the positioning balls cooperate with the first positioning slot to fix the milk cup to prevent it from falling off accidentally.

[0032] In addition, if Figure 2 As shown, the edge of the milk cup has a protruding lip structure, and the edge of the breast shield is correspondingly provided with a groove structure; the lip structure is inserted into the groove structure to achieve sealing.

[0033] like Figure 3 As shown, in this embodiment, a plurality of buckles 19 are provided on the edge of the diaphragm; a concave second positioning slot 20 is provided on the milk cup in a direction corresponding to the buckle; the buckle cooperates with the second positioning slot to realize the connection between the cylinder diaphragm and the milk cup, and plays the role of positioning the diaphragm.

[0034] The wearable breast pump described in the utility model has a receiving cavity or receiving groove inside the main body, and the milk storage container is embedded in the main body. The two are integrated in appearance, and the user can hide the milk storage container under clothes when using it, thereby enhancing privacy. The main body and the milk storage container form an embracing connection relationship, thereby preventing the main body and the milk storage container from accidentally falling off. At the same time, the heavier components inside the main body, such as the air pump, solenoid valve, and battery, are located at the bottom of the entire device, thereby making the breast pump more stable.

[0035] The above description is only a detailed description of the preferred embodiments and principles of the present invention. For ordinary technicians in this field, based on the ideas provided by the present invention, there will be changes in the specific implementation methods, and these changes should also be regarded as the scope of protection of the present invention.
