[0033] The utility model provides a breast pump 100 .
[0034] In the embodiment of the present utility model, in combination with reference Figures 1 to 7 The breast pump 100 includes a collecting component 1, a negative pressure component 2 and a first liquid barrier driving member 3. The collecting component 1 includes a breast shield 11 and a milk storage container 12. The breast shield 11 is connected to the 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 collecting component 1 is provided with a suction port 61; the negative pressure component 2 includes a negative pressure driving mechanism 21 and a negative pressure air path 22. One end of the negative pressure air path 22 is connected to the negative pressure driving mechanism 21, and the other end is connected to the suction port 61 of the collecting component 1; the first liquid barrier driving member 3 is integrally formed with the negative pressure component 2 and sealedly connected. The negative pressure component 2 indirectly applies negative pressure to the collecting component 1 through the first liquid barrier driving member 3. The technical solution of the utility model is to prevent milk from being sucked into the air path.
[0035] In this embodiment, one side of the collecting component 1 is used to fit the breast, and should be made of skin-friendly and soft materials, such as silicone or latex, which are more comfortable and not likely to cause skin allergies and other problems in the user. The other side is used to collect breast milk, and can be made of structures such as a milk bowl, a milk bag or a milk bottle, which is not further limited here. The collecting component 1 includes a breast shield 11 and a milk storage container 12. The milk storage container 12 can be a milk bag, a milk bottle or a milk bowl, etc. 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 respectively, 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 breast shield 11 is used to fit the breast of the user, and is in the shape of a funnel or 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 easy to cause skin allergies and other problems in the user. The negative pressure component 2 indirectly applies negative pressure to the collection component 1 through a liquid barrier driver, 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 negative pressure drive mechanism 21 in the negative pressure component 2 includes but is not limited to a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, etc., which can indirectly cause negative pressure inside the breast shield 11 by transmitting negative pressure to a liquid barrier such as a diaphragm or an air bag, and through the negative pressure, the breast milk is introduced into the collection component 1 for storage. The first liquid barrier driving member 3 can be a diaphragm or an air bag structure, and is arranged in the negative pressure component 2. The negative pressure component 2 indirectly applies negative pressure to the collecting component 1 through the liquid barrier driving member, and can prevent milk from being sucked into the negative pressure component 2.
[0036] The liquid barrier driving member and the negative pressure assembly 2 or the collecting assembly 1 are integrally formed and sealed, which means that the liquid barrier driving member and the negative pressure assembly 2 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 and detachable elastic diaphragm structure used in the breast pump 100 in the prior art 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 100. It can also overcome the problem that the independent and detachable elastic diaphragm structure used in the breast pump 100 in the prior art 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 100.
[0037] The connection between the negative pressure component 2 and the collecting component 1 refers to the negative pressure component 2 used to cause negative pressure in at least part of the space inside the collecting component 1. It can be an air pump such as a diaphragm pump or a piezoelectric ceramic pump, which transmits air pressure to the liquid barrier driving component for deformation movement, thereby causing a change in negative pressure inside the collecting component 1; it can also be a mechanical driving structure that mechanically drives the liquid barrier driving component to deform or reciprocate, thereby causing a change in negative pressure inside the collecting component 1; or the liquid barrier driving component itself may be a piezoelectric material, and after power is turned on, the liquid barrier driving component can self-vibrate or deform, thereby causing a change in negative pressure inside the collecting component 1.
[0038] In one example, the collection component 1 at least includes a breast shield 11 and a milk storage container 12. The breast shield 11 includes a flange end that fits the breast and receives breast milk and an outflow end that flows breast milk into the milk storage container 12. The milk storage container 12 can store breast milk alone or the containing cavity formed with the breast shield 11 can store breast milk. The negative pressure air port can change the internal pressure of the collection component 1 under the action of a liquid barrier driving member (elastic deformation member such as a suction diaphragm or a bag) to guide the breast milk to be sucked out into the milk storage container 12. The negative pressure component 2 includes a negative pressure pump, a negative pressure air path 22 and a negative pressure deformation chamber. The negative pressure deformation chamber has an air suction port. The negative pressure pump can drive the liquid barrier driving member to reciprocate through the air suction port, causing negative pressure to be generated inside the breast shield 11, and guiding the breast milk to flow into the milk storage container 12.
[0039] The negative pressure deformation chamber at least includes a chamber body formed by sealing a part of the liquid barrier driving component and the deformation chamber suction port of the negative pressure air circuit 22; when the negative pressure air pump intermittently inhales air, the negative pressure deformation chamber will be deformed, thereby causing negative pressure to be generated inside the breast shield 11 to guide breast milk to be introduced into the milk storage container 12.
[0040] The host has a negative pressure component 2, which may be an air pump and an air circuit, driving the deformable diaphragm to reciprocate, so as to cause intermittent negative pressure in the breast shield 11, so as to suck milk from the breast milk into the milk storage container 12. It may also be a mechanical driving component. For example, it may be a connecting rod, a cam or a piston mechanism, one end of which is connected to at least part of the diaphragm and can drive the diaphragm to reciprocate, thereby causing the pressure inside the breast shield 11 to change, so as to introduce milk into the milk storage container 12.
[0041] The breast pump 100 proposed in the technical solution of the utility model includes a collecting component 1, a negative pressure component 2 and a first liquid barrier driving component 3. The collecting component 1 includes a breast shield 11 and a milk storage container 12 that are connected. The collecting component 1 is provided with a suction port 61. The negative pressure component 2 includes a negative pressure driving mechanism 21 and a negative pressure air path 22. One end of the negative pressure air path 22 is connected to the negative pressure driving mechanism 21, and the other end is connected to the suction port 61. The first liquid barrier driving component 3 is integrally formed with the negative pressure component 2 and is sealedly connected. The negative pressure component 2 indirectly applies negative pressure to the collecting component 1 through the liquid barrier driving component. The collecting component 1 can transmit the negative pressure to the user's breast through the breast shield 11, suck out the milk in the mammary gland, and flow it into the milk storage container 12 for temporary storage. The liquid barrier driving component can prevent the milk from being sucked into the negative pressure component 2, thereby preventing the contamination of the milk and the damage of the circuit in the negative pressure component 2.
[0042] In one embodiment of the present application, the negative pressure assembly 2 further includes a housing 23, the housing 23 is connected to the collection assembly 1, the negative pressure driving mechanism 21 is at least partially disposed in the housing 23, and the negative pressure gas circuit 22 is at least partially disposed in the housing 23;
[0043] The first liquid barrier driving member 3 is integrally formed with the negative pressure gas path 22 and is sealedly connected.
[0044] In this embodiment, the shell 23 is used to protect the internal negative pressure component 2, and prevent dust and water from bumping. The shell 23 can be made of hard plastic material, or a light metal material, such as aluminum alloy or titanium alloy. The negative pressure drive mechanism 21 and the negative pressure air circuit 22 are at least partially arranged in the shell 23, and the shell 23 is connected to the collection component 1. The negative pressure drive mechanism 21 and the negative pressure air circuit 22 are exposed in the shell 23 and arranged in the collection component 1. The first liquid barrier drive member 3 is integrally formed with the negative pressure air circuit 22 and sealedly connected. The negative pressure component 2 indirectly applies negative pressure to the collection component 1 through the first liquid barrier drive member 3 in the negative pressure air circuit 22, so that the milk flows out of the user's mammary gland and prevents the milk from being sucked into the negative pressure component 2 to cause milk contamination or circuit damage.
[0045] In one embodiment of the present application, the first liquid barrier driving member 3 is integrally formed with the suction port 61 of the collecting assembly 1 and is sealed and connected.
[0046] In this embodiment, the negative pressure driving mechanism 21 is connected to the suction port 61 of the collecting component 1 through the negative pressure air path 22, and the first liquid barrier driving component 3 is integrally formed and sealedly connected to the suction port 61 of the collecting component 1. The negative pressure driving mechanism 21 can indirectly apply negative pressure to the collecting component 1 through the first liquid barrier driving component 3 to allow milk to flow out of the user's mammary gland and prevent the milk from being sucked into the negative pressure component 2 to cause milk contamination or circuit damage.
[0047] In one embodiment of the present application, the first liquid barrier driving component 3 is a diaphragm or an air bag.
[0048] In this embodiment, the first liquid barrier driving member 3 can be made of a deformable elastic material, such as a diaphragm or an air bag made of silicone or rubber material, and the negative pressure is indirectly applied to the collecting component 1 through the pump pressure of the pump component in the negative pressure component 2 and its own deformation, and finally the negative pressure is applied to the user's breast, thereby helping the user to discharge the milk and flow it into the milk storage container 12 for temporary storage.
[0049] In one embodiment of the present application, the breast pump 100 further includes a diaphragm bracket 7 , which is disposed on the collecting assembly 1 and communicated with the collecting assembly 1 , and the first liquid barrier driving member 3 is sandwiched between the diaphragm bracket 7 and the housing 23 .
[0050] In this embodiment, the breast pump 100 also includes a diaphragm bracket 7, which is made of a hard material, such as hard plastic. The diaphragm bracket 7 is bowl-shaped, and the bottom opening of the diaphragm bracket 7 is connected to the collecting component 1. The first liquid barrier driving component 3 is clamped between the top bowl mouth of the diaphragm bracket 7 and the outer shell 23 to limit the movement space and deformation range of the first liquid barrier driving component 3. The first liquid component driving component indirectly applies negative pressure to the collecting component 1 through the diaphragm bracket 7, and finally applies negative pressure to the user's breast to assist the user in discharging milk and flowing it into the milk storage container 12 for temporary storage.
[0051] In one example, the first liquid barrier driving component 3 is integrally formed on a hard diaphragm cover 6 so that a deformable chamber is formed between the first liquid barrier driving component 3 and the diaphragm cover 6. The first liquid barrier driving component 3 can be deformed and reciprocate under the drive of the negative pressure air pump, which can cause the internal air pressure of the breast shield 11 to change, thereby sucking breast milk into the milk storage container 12. The diaphragm cover 6 is detachably installed on the main unit and is connected to the air pump air path in the main unit.
[0052] In one embodiment of the present application, the breast pump 100 further includes a second liquid barrier driving component 4, which is disposed in the collecting component 1 or connected to the first liquid barrier driving component 3, and the negative pressure component 2 applies negative pressure to the collecting component 1 through the first liquid barrier driving component 3 and the second liquid barrier driving component 4.
[0053] In this embodiment, the breast pump 100 is further provided with a second liquid barrier driving component 4, which is arranged in the collecting component 1 or directly or indirectly connected to the first liquid barrier driving component 3. The negative pressure component 2 applies negative pressure to the collecting component 1 through two layers of barrier driving components, which can further increase the air tightness of the breast pump 100, reduce the probability of milk being sucked into the negative pressure component 2, and increase the service life of the breast pump 100.
[0054] In one embodiment of the present application, the first liquid barrier driving member 3 and the second liquid barrier driving member 4 are integrally formed and enclose a sealed space;
[0055] Alternatively, the first liquid barrier driving component 3 is tightly connected to the second liquid barrier driving component 4 .
[0056] In this embodiment, the first liquid barrier driver 3 and the second liquid barrier driver 4 are integrally formed, and a sealed space can be enclosed between the first liquid barrier driver 3 and the second liquid barrier driver 4, and the negative pressure is indirectly transferred from the second liquid barrier driver 4 to the first liquid barrier driver 3 through the sealed space, or the first liquid barrier driver 3 and the second liquid barrier driver 4 are closely connected, and the negative pressure is directly transferred from the second liquid barrier driver 4 to the first liquid barrier driver 3, so as to realize the transmission of negative pressure, and finally the negative pressure is applied to the collection component 1, and the milk is sucked out of the mammary gland and flows into the milk storage container 12 for temporary storage. Since the negative pressure component 2 indirectly applies negative pressure to the mobile phone through the first liquid barrier driver 3 and the second liquid barrier driver 4, the occurrence of accidents in which the milk is sucked into the negative pressure component 2 can be reduced.
[0057] In an embodiment of the present application, the first liquid barrier driving component 3 and the second liquid barrier driving component 4 form a flat disc-shaped component.
[0058] In this embodiment, the first liquid barrier driving member 3 and the second liquid barrier driving member 4 form a flat disc-shaped component. The disc-shaped component can be a sac-shaped object with a space in the middle, or a double-layer tightly fitted component, which is not further limited here.
[0059] In one embodiment of the present application, the breast pump 100 further includes a connecting member 5, the first liquid barrier driving member 3 is sealedly connected to one end of the connecting member 5, the second liquid barrier driving member 4 is sealedly connected to the other end of the connection, and the first liquid barrier driving member 3 and the second liquid barrier driving member 4 are enclosed to form a sealed space or a tight fit.
[0060] In this embodiment, the first liquid barrier driver 3 and the second liquid barrier driver 4 are connected as one body through the intermediate connecting member 5, and a sealed space is enclosed between the first liquid barrier driver 3 and the second liquid barrier driver 4, and the negative pressure is indirectly transferred from the second liquid barrier driver 4 to the first liquid barrier driver 3 through the sealed space, or the first liquid barrier driver 3 and the second liquid barrier driver 4 are tightly connected, and the negative pressure is directly transferred from the second liquid barrier driver 4 to the first liquid barrier driver 3, so as to realize the transmission of negative pressure, and finally the negative pressure is applied to the collection component 1, and the milk is sucked out of the mammary gland and flows into the milk storage container 12 for temporary storage. Since the negative pressure component 2 indirectly applies negative pressure to the mobile phone through the first liquid barrier driver 3 and the second liquid barrier driver 4, the occurrence of accidents in which the milk is sucked into the negative pressure component 2 can be reduced.
[0061] In one embodiment of the present application, the connecting member 5 is a support frame arranged along the periphery of the first liquid barrier driving member 3 and the second liquid barrier driving member 4 , and the support frame defines the periphery shape of the first liquid barrier driving member 3 and the second liquid barrier driving member 4 .
[0062] In this embodiment, the support frame can be a structure that clamps the first liquid barrier driving member 3 and the second liquid barrier driving member 4 to form a seal; or the first liquid barrier driving member 3 and the second liquid barrier driving member 4 are arranged at an interval, and the support frame is arranged between the two, and a sealing structure is formed between the support frame and the first liquid barrier driving member 3 and the second liquid barrier driving member 4; or the first liquid barrier driving member 3 and the second liquid barrier driving member 4 are integrally formed with the support frame to form a sealing structure, which is not further limited here.
[0063] In one embodiment of the present application, the second liquid barrier driving member 4 is a disposable sheet-like barrier deformation structure.
[0064] In this embodiment, since the second liquid barrier driver 4 is disposed close to the breast shield 11 and will come into direct contact with the breast milk, the second liquid barrier driver 4 can be disposed as a disposable sheet-shaped barrier deformation structure. After a single use, it can be discarded and replaced with a new second liquid barrier driver 4, thereby reducing the cleaning operation, preventing the risk of water entering the breast pump 100 during cleaning, and increasing the service life of the breast pump 100. The breast pump 100 can be designed as a shared breast pump 100 for emergency use, and mutual contamination can be prevented by using a disposable second liquid barrier driver 4.
[0065] In one example, the first liquid barrier driving component 3 is integrally formed on the main unit, or on a diaphragm cover 6 that can be detachably connected to the main unit. The second liquid barrier driving component 4 is arranged outside the first liquid barrier driving component 3. The first liquid barrier driving component 3 can drive the second liquid barrier driving component 4 to vibrate to cause a change in the internal air pressure of the breast shield 11, thereby introducing milk from the breast into the milk storage container 12.
[0066] Preferably, the second liquid barrier driver 4 is a disposable film, which can be attached to the outside of the first liquid barrier driver 3 (the side close to the nipple channel). After milking is completed, the second liquid barrier driver 4 can be torn off or disassembled from the first liquid barrier driver 3 and discarded, which can avoid the need to clean the first liquid barrier driver 3 integrally formed on the main unit or the diaphragm cover 6, which is convenient and hygienic, and can also avoid damage to components such as the internal circuit of the main unit due to cleaning.
[0067] Preferably, the second liquid barrier driving member 4 can be integrally formed on the milk bowl or the tee (or the breast shield 11), and the second liquid barrier driving member 4 can also be a separate detachable structure, which can be deformed by the deformation of the first liquid barrier driving member 3, and can prevent the first liquid barrier driving member 3 from directly contacting the milk. When the main unit is separated from the milk bowl, the first liquid barrier driving member 3 and the second liquid barrier driving member 4 are separated together.
