[0034] The current breast pump directly applies negative pressure to the breast through a negative pressure air circuit, which may cause milk to be sucked into the air circuit at the same time, which may easily cause milk contamination or affect the circuit or pump at the main end of the air circuit. The current method is to set a detachable liquid barrier drive part in the negative pressure air circuit, which is easy to be installed out of place after the user disassembles and cleans it, causing the risk of milk leakage and backflow. Therefore, the utility model proposes a fully enclosed breast pump that can prevent milk from being sucked into the air circuit.

[0035] The utility model provides a fully enclosed breast pump 100.

[0036] In the embodiment of the present utility model, in combination with reference Figures 1 to 9The fully enclosed breast pump 100 includes a collecting component 1, a liquid barrier driving component 2 and a negative pressure component 3. The collecting component 1 includes a breast shield 11 and a milk storage container 12. The breast shield 11 is used to fit the breast, and the milk storage container 12 is used to collect milk. The breast shield 11 is connected to the milk storage container 12; the liquid barrier driving component 2 is integrally formed with the collecting component 1 and is sealed to the collecting component 1; the negative pressure component 3 is pneumatically, mechanically or electrically connected to the collecting component 1, and applies negative pressure to the collecting component 1 through the liquid barrier driving component 2. The liquid barrier driving component 2 separates the breast pump into two parts separated by gas and liquid.

[0037] In this embodiment, the collection component 1 includes a breast shield 11 for fitting the breast. The breast shield 11 is used to fit the breast of the user, and is in the shape of a funnel or a hemisphere that can fit the breast. In order to improve the user experience, the breast shield 11 is made of a skin-friendly and soft material, such as silicone or latex, which is more comfortable and not likely to cause skin allergies and other problems in the user. The milk storage container 12 on the other side is used to collect milk, and can be a milk bowl, a milk bag or a milk bottle, etc., which is not further limited here. The liquid barrier drive member 2 can be a diaphragm or an air bag, and can be integrally formed with the collection component 1 to form a sealing structure, which cannot be disassembled, and can prevent the user from disassembling and installing it in a misaligned position, causing milk leakage or backflow. The milk storage container 12 can be directly connected to the breast shield 11, or can be connected through a shorter pipe, or the milk bowl can surround the breast shield 11 to form an independent wearing unit; the two can be an integral whole, or a detachable structure, or the milk bowl or milk bottle can be connected to a shell separately, but the two are connected by a channel, so that breast milk can flow from the breast shield 11 into the milk storage container 12. The negative pressure component 3 indirectly applies negative pressure to the collection component 1 through the liquid barrier driving member 2, so that the collection component 1 squeezes the breast, which can help the user discharge milk from the breast and flow into the collection component 1 for temporary storage. The power structure used to generate negative pressure in the negative pressure component 3 includes but is not limited to a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, etc., which can be a negative pressure transmitted to a liquid barrier such as a diaphragm or an air bag to indirectly cause negative pressure inside the breast shield 11, and through the negative pressure, the breast milk is introduced into the collection component 1 for storage.

[0038] The liquid barrier drive member 2 and the negative pressure assembly 3 or the collecting assembly 1 are integrally formed and sealed, which means that the liquid barrier drive member 2 and the negative pressure assembly 3 or the collecting assembly 1 are an inseparable whole, and there is no gap between the two, and there is no need to seal the two by installation, extrusion or other clamping structures. The purpose of such a setting is to effectively overcome the problem that the independent detachable elastic diaphragm structure used in the prior art breast pump may fail to seal the liquid due to problems such as installation misalignment or edge wrinkles during use, thereby causing major accidents such as milk contamination or damage to the electronic components of the breast pump host. It can also overcome the problem that the independent detachable elastic diaphragm structure used in the prior art breast pump needs to be cleaned separately, which is troublesome to clean, and the elastic diaphragm structure may be disassembled and installed again after cleaning, which may cause liquid sealing failure, thereby causing major accidents such as milk contamination or damage to the electronic components of the breast pump host.

[0039] The connection between the negative pressure component 3 and the collecting component 1 refers to the negative pressure component 3 used to cause negative pressure in at least part of the space inside the collecting component 1. It can be a diaphragm pump, a piezoelectric ceramic pump or other air pump that transmits air pressure to the liquid barrier driver 2 for deformation movement, thereby causing a change in the negative pressure inside the collecting component 1; it can also be a mechanical driving structure that mechanically drives the liquid barrier driver 2 to deform or reciprocate, thereby causing a change in the negative pressure inside the collecting component 1; or the liquid barrier driver 2 itself may be a piezoelectric material, and after power is turned on, the liquid barrier driver 2 can self-vibrate or deform, thereby causing a change in the negative pressure inside the collecting component 1.

The liquid barrier driving member 2 is integrally formed and arranged on the collecting component 1. When the user uses it, the collecting component 1 is partially attached to the breast. The negative pressure component 3 indirectly applies negative pressure to the collecting component 1 through the liquid barrier driving member 2, so that the milk can be sucked out from the user's breast and then flow into the collecting component 1 for temporary storage. The liquid barrier driving member 2, which is integrally formed and sealed with the collecting component 1, can separate the breast pump into two gas-liquid separated parts, one part is used for milk circulation, and the other part is used for communicating with the air path of the negative pressure component 3 to form negative pressure. The liquid barrier driving member 2 can prevent the milk from being sucked into the air path of the negative pressure component 3, thereby preventing the milk from being contaminated or causing the negative pressure component 3 to short-circuit and fail.

[0068] In one example, the liquid barrier driving member 2 is made of an elastically deformable material, such as silicone or rubber. The elastically deformable portion can be deformed under the action of the negative pressure component 3, and due to the presence of the folds, the deformation volume is larger and can withstand more negative pressure, which can cause a greater negative pressure on the nipple accommodating portion 112, thereby improving the milk suction efficiency of the breast pump.

[0069] The negative pressure component 3 in the breast pump proposed in the present invention can be a pump component, such as an air pump, a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, etc., or other driving structures that can cause the diaphragm to reciprocate. For example, the diaphragm can be at least partially connected to a reciprocating piston, a cam, a rocker rod, etc. The electrode drives the piston to reciprocate and drives the diaphragm to reciprocate, causing negative pressure to be generated inside the flange 111.

[0070] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
