Description

breast pump Technical Field

[0001] The present application relates to the technical field of maternal and infant products, and in particular to a breast pump. Background Art

[0002] A breast pump is a tool used to express breast milk accumulated in the mammary glands. It is generally used when the baby is unable to suck breast milk directly, or when the mother is away from the baby but still wants to breastfeed.

[0003] In the prior art, breast pumps usually use an electric or manual negative pressure system to directly or indirectly apply negative pressure to a breast shield or milk storage container that fits the breast, so that milk can be sucked into the milk storage container or other storage space for storage. The original breast pumps directly applied negative pressure to the breast through a negative pressure air circuit, but there was a situation where milk was also sucked into the air circuit at the same time, which could easily cause milk contamination or affect the circuit or pump on the main end of the air circuit. Based on such problems, breast pumps need to be improved.

[0092] The present application provides a breast pump 100 .

[0093] In the embodiment of the present application, referring to Figures 1 to 6, the 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 with the collecting component 1; the negative pressure component 3 is 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 100 into two parts separated by gas and liquid.

[0094] In this embodiment, the collection assembly 1 includes a breast shield 11 for fitting onto the breast. The breast shield 11 is funnel-shaped or hemispherical, and to enhance the user experience, the breast shield 11 is made of a soft, skin-friendly material, such as silicone or latex, which is comfortable and less likely to cause skin allergies. A milk storage container 12 on the other side is used to collect milk and can be a bowl, bag, or bottle, without further limitation. The liquid barrier driver 2 can be a diaphragm or airbag, and is integrally formed with the collection assembly 1 to form a sealed structure. This seal is non-detachable, preventing disassembly and misplacement, which could result in milk leakage or backflow. The milk storage container 12 can be directly connected to the breast shield 11, connected via a short tube, or with a bowl surrounding the breast shield 11 to form a separate wearable unit. The two can be integral or detachable, or the bowl or bottle can be separately connected to a housing, with a passageway between them, allowing breast milk to flow from the breast shield 11 into the milk storage container 12. The negative pressure assembly 3 indirectly applies negative pressure to the collection assembly 1 via the liquid barrier driver 2, causing the collection assembly 1 to compress the breast, helping the user drain milk from the breast and allowing it to flow into the collection assembly 1 for temporary storage. The power structure used to generate negative pressure in the negative pressure assembly 3 includes, but is not limited to, a piezoelectric pump, a diaphragm pump, a hydraulic pump, or a mechanical pump. This negative pressure can be indirectly generated by transmitting it to a liquid barrier such as a diaphragm or air bladder, thereby drawing breast milk into the collection assembly 1 for storage.

[0095] The breast pump 100 proposed in the technical solution of the present application includes a collection component 1, a negative pressure component 3 and a liquid barrier driver 2. The liquid barrier driver 2 is integrally formed on the collection component 1. When in use, the user places part of the collection component 1 on the breast, and the negative pressure component 3 indirectly applies negative pressure to the collection component 1 through the liquid barrier driver 2, so that milk can be sucked out of the user's breast and then flow into the collection component 1 for temporary storage. The liquid barrier driver 2, which is integrally formed and sealed with the collection component 1, can separate the breast pump 100 into two parts for gas-liquid separation, one part is used for milk circulation, and the other part is used to communicate with the air path of the negative pressure component 3 to form negative pressure. The provision of the liquid barrier driver 2 can prevent 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.

[0096] In one embodiment of the present application, the breast shield 11 and the milk storage container 12 are integrally formed, and a milk storage space is enclosed between the breast shield 11 and the milk storage container 12 .

[0097] In this embodiment, the breast shield 11 and the milk storage container 12 are integrally formed, with a milk storage space formed in the middle, which can improve the sealing of the milk storage space and prevent milk leakage from the milk storage space due to repeated disassembly and installation.

[0098] In one embodiment of the present application, the breast shield 11 and the milk storage container 12 are detachably connected, and a milk storage space is enclosed between the breast shield 11 and the milk storage container 12 .

[0099] In this embodiment, the breast shield 11 and the milk storage container 12 are detachably connected, and a snap connection or a screw connection can be adopted. A milk storage space is enclosed between the breast shield 11 and the milk storage container 12. The detachable connection of the breast shield 11 and the milk storage container 12 can facilitate the user to clean and dry them.

[0100] In one embodiment of the present application, the milk storage container 12 is a milk bowl, a milk bottle, or a milk bag;

[0101] A milk suction passage is formed on the side of the breast shield 11 facing away from the breast, and one end of the milk suction passage facing away from the breast is communicated with the milk storage container 12 .

[0102] In this embodiment, the milk storage container 12 can be a structure such as a milk bowl, a milk bottle, or a milk bag. A milk suction channel is formed on the side of the breast shield 11 facing away from the breast. The milk suction channel can be directly connected to and communicated with the milk bowl, the milk bottle, or the milk bag, or can be connected to and communicated with the milk bowl, the milk bottle, or the milk bag through a short pipe. Milk can flow directly from the breast into the milk bowl, the milk bottle, or the milk bag through the milk suction channel for storage.

[0103] In one embodiment of the present application, the liquid barrier driving member 2 is integrally formed with the milk storage container 12 and is sealedly connected to the milk storage container 12 to separate the breast pump 100 into two gas-liquid separated parts.

[0104] In this embodiment, the liquid barrier driver 2 is integrally formed with the milk storage container 12 and sealed, dividing the breast pump 100 into two gas-liquid separations. One section allows milk to flow, ultimately into the milk storage container 12 for temporary storage. The other section allows the negative pressure assembly 3 to apply negative pressure to the liquid barrier driver 2, indirectly applying negative pressure to the space within the breast shield 11 and milk storage container 12. Ultimately, this negative pressure is applied to the user's breast, helping the user express milk from the mammary gland. The liquid barrier driver 2 prevents milk from being drawn into the air path of the negative pressure assembly 3, thereby preventing milk contamination or short-circuiting the negative pressure assembly 3.

[0105] It will be appreciated that, in one embodiment, the milk storage container 12 utilizes a bowl structure, and the liquid barrier driver 2 utilizes a diaphragm integrated into the center portion of the bowl. The bowl is provided with a support structure constructed of hard rubber, while the diaphragm is constructed of soft rubber. The diaphragm can be integrally formed with the support structure through a rubber encapsulation process, thereby separating the breast pump 100 into two gas-liquid separation sections. The flange 111 can be constructed of either hard or soft rubber, and is sealed to the bowl to form the milk storage container 12. The negative pressure assembly 3 includes an air pump, which applies negative pressure through the negative pressure vents, causing the diaphragm to deform and reciprocate, generating negative pressure within the milk storage container 12. This in turn generates negative pressure within the flange 111, drawing milk from the nipple into the bowl for collection and temporary storage.

[0106] In another embodiment, the milk storage container 12 adopts a milk bowl structure, the liquid barrier driving component 2 adopts a diaphragm structure, the diaphragm is integrated in the upper part of the milk bowl, and the diaphragm bracket 21 is integrated on the flange 111. The diaphragm bracket 21 adopts a hard material, such as plastic or metal. The flange 111 can adopt a hard rubber material or a soft rubber material, and is sealed with the milk bowl to form the milk storage container 12. An air pump is provided in the main unit, and a negative pressure air hole is provided at the bottom of the main unit. A plug-in tube is protruded from the milk bowl, and the plug-in tube is detachably and sealedly connected to the negative pressure air hole. The air pump applies negative pressure through the negative pressure air hole and the plug-in tube, causing the diaphragm to deform and reciprocate, thereby causing negative pressure to be generated in the flange 111, and the milk is drawn from the nipple to the milk bowl for collection and temporary storage.

[0107] In another embodiment, the milk storage container 12 adopts a milk bowl structure, the flange 111 can be made of hard rubber material or soft rubber material, and is detachably sealed with the milk bowl to form the milk storage container 12, the liquid barrier driving component 2 adopts a diaphragm structure, and a diaphragm cover 4 is provided on the milk bowl. The milk bowl and the diaphragm cover 4 are both made of hard rubber material, the diaphragm is made of soft rubber material, the diaphragm cover 4 is sealed to the milk bowl, and a negative pressure pore is provided on the diaphragm cover 4. The negative pressure pore communicates with the cavity enclosed between the diaphragm cover 4 and the diaphragm. The diaphragm can reciprocate in the cavity, causing negative pressure to be generated in the milk storage container 12, and then causing negative pressure to be generated in the flange 111, thereby drawing milk from the nipple into the milk bowl for collection and temporary storage.

[0108] In yet another embodiment, the milk storage container 12 utilizes a bowl structure. The flange 111 can be made of either hard or soft rubber and is integrally connected to the bowl to form the milk storage container 12. The liquid barrier driver 2 utilizes a diaphragm structure, with a diaphragm cover 4 positioned above the bowl. Both the bowl and the diaphragm cover 4 are made of hard rubber, while the diaphragm is made of soft rubber. The diaphragm cover 4 is sealed to the bowl and has negative pressure vents disposed thereon. The negative pressure vents communicate with the chamber enclosed between the diaphragm cover 4 and the diaphragm. The diaphragm can reciprocate within the chamber, generating negative pressure within the milk storage container 12, which in turn generates negative pressure within the flange 111, drawing milk from the nipple into the bowl for collection and temporary storage. The flange 111, bowl, and diaphragm can be assembled into a disposable, easily replaceable unit without cleaning, making it convenient for users to share the negative pressure assembly 3.

[0109] In one embodiment of the present application, the collecting assembly 1 further comprises a three-way assembly 13 having three openings connected to one another, wherein the first opening is connected to the breast shield 11, the second opening is connected to the negative pressure assembly 3, and the third opening is connected to the milk storage container 12. The liquid barrier driving component 2 is disposed in the three-way assembly 13 and is integrally formed with the three-way assembly 13 and sealedly connected thereto. The liquid barrier driving component 2 separates the three-way assembly 13 into two parts for gas-liquid separation, and the negative pressure assembly 3 indirectly applies negative pressure to the three-way assembly 13 via the liquid barrier driving component 2.

[0110] In this embodiment, the collection assembly 1 also includes a three-way assembly 13, which includes a first opening, a second opening, and a third opening that communicate with each other. The first opening is for communication with the breast shield 11, the second opening is for communication with the negative pressure assembly 3, and the third opening is for communication with the milk storage container 12. The liquid barrier driver 2, which can be a diaphragm or airbag structure, is integrally formed within the three-way assembly 13 and sealed therewith. The negative pressure assembly 3 and the liquid barrier driver 2 apply negative pressure to the three-way assembly 13, which in turn applies negative pressure to the collection assembly 1, ultimately applying negative pressure to the user's breast, helping the user express milk from the mammary gland. The milk then flows through the breast shield 11 into the milk storage container 12 for temporary storage. The liquid barrier driver 2 disposed in the three-way assembly 13 prevents milk from being drawn into the negative pressure assembly 3, thereby preventing milk contamination or short circuiting of the negative pressure assembly 3.

[0111] In one example, the three-way component 13 is made of hard rubber material, and a diaphragm bracket 21 is integrated on the three-way component 13. The diaphragm bracket 21 is also made of hard rubber material, and the diaphragm is made of soft rubber material. It is arranged on the diaphragm bracket 21 through a rubber coating process. The diaphragm bracket 21 and the main body are enclosed to form a diaphragm space. The diaphragm can deform and reciprocate in the diaphragm space, causing a negative pressure change in the tee, and then causing a negative pressure in the flange 111, drawing the milk from the nipple to the milk bowl for collection and temporary storage.

[0112] In one embodiment of the present application, the liquid barrier driving component 2 is a diaphragm, and the edge of the diaphragm is sealed and connected to the edge of the second opening to cover the second opening.

[0113] In this embodiment, a diaphragm is used as the liquid barrier driving member 2. The diaphragm is made of a deformable material. For example, the edge of the diaphragm is integrally connected to the edge of the second opening and covers the second opening. The negative pressure component 3 can apply negative pressure to the diaphragm, causing the diaphragm to deform, thereby applying negative pressure to the inside of the three-way component 13, and then applying negative pressure to the inside of the collecting component 1. Finally, the negative pressure is applied to the user's breast, helping the user to squeeze out the milk in the mammary gland, and the milk flows into the milk storage container 12 through the breast shield 11 for temporary storage.

[0114] In one embodiment of the present application, the breast shield 11 includes a flange 111 and a nipple receiving portion 112. The nipple receiving portion 112 has openings at both ends and is connected thereto. The flange 111 is connected to an opening of the nipple receiving portion 112. The flange 111 is used to abut against the breast. The liquid barrier driver 2 is integrally formed with the flange 111 and is sealed therewith. The negative pressure assembly 3 indirectly applies negative pressure to the flange 111 via the liquid barrier driver 2.

[0115] Alternatively, the liquid barrier driver 2 is disposed at another opening of the nipple accommodating portion 112 and is sealedly connected to the other opening of the nipple accommodating portion 112 , and the negative pressure component 3 indirectly applies negative pressure to the nipple accommodating portion 112 through the liquid barrier driver 2 .

[0116] In this embodiment, the breast shield 11 includes a flange 111 and a nipple receiving portion 112. The nipple receiving portion 112 is open at both ends and is through-hole, for accommodating the nipple. The nipple receiving portion 112 can be made of a rigid material, such as plastic, metal tube, glass tube, etc., or a flexible or semi-flexible material, such as rubber or silicone, without specific limitation herein. The flange 111 is made of a flexible material, such as rubber or silicone. When negative pressure is applied to the flange 111, the flange 111 deforms, transmitting the negative pressure to the user's breast, further improving milk ejection efficiency. A liquid barrier driver 2 is integrally formed with the flange 111. The negative pressure assembly 3 applies negative pressure to the liquid barrier driver 2, which in turn applies negative pressure to the flange 111, ultimately applying negative pressure to the user's breast, helping to express milk from the mammary gland. The milk then flows through the breast shield 11 into the milk storage container 12 for temporary storage. The liquid barrier driver 2 is arranged on the flange 111, and the air path of the negative pressure assembly 3 is not connected to the flange 111 and / or the nipple receiving portion 112, so there is no risk of contaminating milk or damaging the circuit.

[0117] In one example, the liquid barrier driver 2 is positioned at another opening of the nipple receiving portion 112, and the negative pressure assembly 3 indirectly applies negative pressure to the liquid barrier driver 2. The liquid barrier driver 2 is made of an elastically deformable material and can deform, thereby applying negative pressure to the nipple receiving portion 112, and ultimately to the user's breast, helping to express milk from the mammary gland. The milk flows through the breast shield 11 into the milk storage container 12 for temporary storage. The liquid barrier driver 2 is positioned at another opening of the nipple receiving portion 112, allowing milk to flow directly from the nipple receiving portion 112 into the milk storage container 12. The liquid barrier driver 2 prevents milk from being drawn into the negative pressure assembly 3, potentially contaminating the milk or damaging the circuitry.

[0118] In one embodiment of the present application, the liquid barrier driver 2 includes a diaphragm bracket 21 and a pressure diaphragm 22. The diaphragm bracket 21 is integrally formed and arranged on the flange 111 or the nipple receiving portion 112. The pressure diaphragm 22 is connected to the diaphragm bracket 21. The negative pressure component 3 indirectly applies negative pressure to the flange 111 through the pressure diaphragm 22.

[0119] In this embodiment, the flange 111 or the nipple receiving portion 112 is provided with a diaphragm bracket 21, and a pressure diaphragm 22 is provided on the diaphragm bracket 21. The diaphragm bracket 21 is connected to the flange 111. The negative pressure component 3 can indirectly apply a negative pressure effect to the flange 111 or the nipple receiving portion 112 through the pressure diaphragm 22, and finally apply negative pressure to the user's breast, helping the user to squeeze out the milk in the mammary gland, and the milk flows into the milk storage container 12 through the breast shield 11 for temporary storage.

[0120] In one example, the milk storage container 12 adopts a milk bowl structure, the flange 111 can be made of hard rubber material or soft rubber material, and is detachably sealed with the milk bowl to form the milk storage container 12, the liquid barrier driving component 2 adopts a diaphragm structure, and a negative pressure chamber is provided on the milk bowl. The end of the flange 111 is sealed with the opening of the negative pressure chamber, and a negative pressure air hole is provided on the outside of the negative pressure chamber for connecting to the air pump and the negative pressure pipeline in the negative pressure component 3, so that the diaphragm can deform and reciprocate in the negative pressure chamber, thereby causing negative pressure to be generated in the flange 111, and the milk is drawn from the nipple to the milk bowl for collection and temporary storage.

[0121] In one embodiment of the present application, the liquid barrier driver 2 includes a connecting portion and an elastic deformation portion, one end of the connecting portion is connected to and communicates with the other opening of the nipple accommodating portion 112, and the edge of the elastic deformation portion is connected to the other end of the connecting portion.

[0122] In this embodiment, the liquid barrier driver 2 includes a connecting portion and an elastically deformable portion. One end of the connecting portion is connectable to and communicates with the other opening of the nipple receiving portion 112. The elastically deformable portion is capped at the other end of the connecting portion and is made of an elastically deformable material. The negative pressure assembly 3 applies negative pressure to the elastically deformable portion, causing it to deform, thereby applying negative pressure within the nipple receiving portion 112 and ultimately to the user's breast, helping the user express milk from the mammary gland. The milk then flows through the breast shield 11 into the milk storage container 12 for temporary storage. The connecting portion and the elastically deformable portion prevent milk from being drawn into the air path of the negative pressure assembly 3, potentially contaminating the milk or causing a short circuit.

[0123] 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. 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 receiving portion 112, thereby improving the milk suction efficiency of the breast pump 100.

[0124] The negative pressure component 3 in the breast pump 100 proposed in the present application can be a negative pressure drive component 31, such as an air pump, a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, etc., or other drive structures that can cause the diaphragm to deform reciprocally. For example, the diaphragm can be at least partially connected to a reciprocating piston, cam, 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.

[0125] The present application also proposes a breast pump 100, referring to Figures 7 to 10. In the embodiment of the present application, the breast pump 100 includes a collecting component 1, a first deformation driving part 23 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 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 41; the first deformation driving part 23 is sealed in the suction port 41, and can cause intermittent negative pressure to be formed in at least part of the space inside the collecting component 1 through deformation and reciprocating motion; one end of the negative pressure component 3 is connected to the negative pressure driving mechanism, and the other end is connected to the first deformation driving part 23; the first deformation driving part 23 and the negative pressure component 3 are integrally formed and sealed, and the negative pressure component 3 indirectly applies negative pressure to the collecting component 1 through the first deformation driving part 23.

[0126] In this embodiment, one side of the collection assembly 1 is designed to conform to the breast and should be made of a soft, skin-friendly material, such as silicone or latex, for increased comfort and less likely to cause skin allergies or other issues. The other side is used to collect breast milk and can be constructed using a milk bowl, milk bag, or milk bottle, without further limitation. The collection assembly 1 includes a breast shield 11 and a milk storage container 12. The milk storage container 12 can be a milk bag, milk bottle, or milk bowl. The milk storage container 12 can be directly connected to the breast shield 11, connected via a short tube, or with the milk bowl surrounding the breast shield 11 to form a separate wearable unit. The two can be integral or detachable, or the milk bowl or milk bottle can be connected separately to a housing, with a passageway between them connecting them, allowing breast milk to flow from the breast shield 11 into the milk storage container 12. Breast shield 11 is designed to fit the user's breast and is shaped like a funnel or hemisphere to fit the breast. To enhance the user experience, breast shield 11 is made of a soft, skin-friendly material, such as silicone or latex, which is comfortable and less likely to cause skin allergies. Negative pressure assembly 3 indirectly applies negative pressure to collection assembly 1 via liquid barrier driver 2, causing collection assembly 1 to squeeze the breast, helping the user drain milk from the breast and allowing it to flow into collection assembly 1 for temporary storage. The negative pressure drive mechanism in negative pressure assembly 3 includes, but is not limited to, a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, and the like. It can indirectly induce negative pressure within breast shield 11 by transmitting negative pressure to a liquid barrier, such as a diaphragm or airbag, and thereby draw breast milk into collection assembly 1 for storage. The first deformation driving part 23 can adopt a structure such as a diaphragm or an airbag, and is arranged in the negative pressure component 3. The negative pressure component 3 indirectly applies negative pressure to the collecting component 1 through the liquid barrier driving part 2, and can prevent milk from being sucked into the negative pressure component 3.

[0127] In one example, the collection assembly 1 includes at least a breast shield 11 and a milk storage container 12. The breast shield 11 includes a flange 111 that fits against the breast and receives breast milk, and an outlet for transferring breast milk into the milk storage container 12. The milk storage container 12 can store breast milk alone or, together with the breast shield 11, form a housing for storing breast milk. A negative pressure vent, under the action of a liquid barrier actuator 2 (an elastically deformable member such as a suction diaphragm or bladder), changes the internal pressure of the collection assembly 1 to guide the breast milk into the milk storage container 12. The negative pressure assembly 3 includes a negative pressure pump, a negative pressure air path 32, and a negative pressure deformation chamber 5. The negative pressure deformation chamber 5 has a suction port. The negative pressure pump drives the liquid barrier actuator 2 to reciprocate, generating a negative pressure inside the breast shield 11 and guiding the breast milk into the milk storage container 12.

[0128] The liquid barrier driver 2 and the negative pressure assembly 3 or the collection assembly 1 are integrally formed and sealed, meaning that the liquid barrier driver 2 and the negative pressure assembly 3 or the collection assembly 1 are an inseparable whole, with no gap between them, and no need for installation, squeezing, or other clamping structures to achieve a seal therebetween. This arrangement effectively overcomes the problem of the independently detachable elastic diaphragm structure used in the prior art breast pump 100, which may fail to seal the liquid during use due to problems such as misalignment or edge wrinkling, thereby causing serious accidents such as milk contamination or damage to the electronic components of the breast pump 100. It also overcomes the problem of the independently detachable elastic diaphragm structure used in the prior art breast pump 100, which requires separate cleaning, which is cumbersome, and may also fail to seal the liquid after disassembly and cleaning, resulting in misalignment, which may cause serious accidents such as milk contamination or damage to the electronic components of the breast pump 100.

[0129] The connection between the negative pressure component 3 and the collection component 1 refers to the negative pressure component 3 used to cause negative pressure in at least part of the space inside the collection 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 driver 2 for deformation movement, thereby causing a change in negative pressure inside the collection component 1; it can also be a mechanical drive structure that mechanically drives the liquid barrier driver 2 to deform or reciprocate, thereby causing a change in negative pressure inside the collection component 1; or the liquid barrier driver 2 itself can be a piezoelectric material, and after power is applied, the liquid barrier driver 2 can self-vibrate or deform, thereby causing a change in negative pressure inside the collection component 1.

[0130] The negative pressure deformation chamber 5 includes at least a portion of the liquid barrier driving member 2 and a chamber body sealed with the deformation chamber suction port of the negative pressure air circuit 32. When the negative pressure air pump intermittently inhales air, the negative pressure deformation chamber 5 is deformed, thereby generating negative pressure inside the breast shield 11 to guide breast milk into the milk storage container 12.

[0131] The main unit includes a negative pressure assembly 3, which can be an air pump and air circuit that drives the deformable diaphragm to reciprocate, thereby generating intermittent negative pressure within the breast shield 11 and drawing milk from the breast into the milk storage container 12. Alternatively, the assembly can be a mechanical drive assembly. For example, it can be a connecting rod, cam, or piston mechanism, one end of which is connected to at least a portion of the diaphragm and is capable of driving the diaphragm to reciprocate, thereby causing pressure changes within the breast shield 11 and drawing milk into the milk storage container 12.

[0132] The breast pump 100 proposed in the technical solution of the present application includes a collecting component 1, a negative pressure component 3 and a first deformation driving part 23. 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 41. The negative pressure component 3 includes a negative pressure driving mechanism and a negative pressure air path 32. One end of the negative pressure air path 32 is connected to the negative pressure driving mechanism, and the other end is connected to the suction port 41. The first deformation driving part 23 is integrally formed with the negative pressure component 3 and is sealed. The negative pressure component 3 indirectly applies negative pressure to the collecting component 1 through the liquid barrier driving part 2. 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 part 2 can prevent the milk from being sucked into the negative pressure component 3, thereby preventing contamination of the milk and damage to the circuit in the negative pressure component 3.

[0133] In one embodiment of the present application, the negative pressure assembly 3 further includes a negative pressure air circuit 32 and a housing 33. The housing 33 is connected to the collection assembly 1. The negative pressure drive mechanism is at least partially disposed within the housing 33. The negative pressure air circuit 32 is at least partially disposed within the housing 33.

[0134] The first deformation driving part 23 and the negative pressure air path 32 are integrally formed and sealed.

[0135] In this embodiment, the outer shell 33 is used to protect the internal negative pressure component 3, and prevent dust, water and bumps. The outer shell 33 can be made of hard plastic material, or a lightweight metal material, such as aluminum alloy or titanium alloy. The negative pressure drive mechanism and the negative pressure air circuit 32 are at least partially arranged in the outer shell 33. The outer shell 33 is connected to the collection component 1, and the part of the negative pressure drive mechanism and the negative pressure air circuit 32 exposed in the outer shell 33 is arranged in the collection component 1. The first deformation drive part 23 is integrally formed with the negative pressure air circuit 32 and is sealed. The negative pressure component 3 indirectly applies negative pressure to the collection component 1 through the first deformation drive part 23 in the negative pressure air circuit 32, so that milk flows out of the user's mammary gland and prevents milk from being sucked into the negative pressure component 3, causing milk contamination or circuit damage. The negative pressure component 3 includes a negative pressure drive mechanism and a negative pressure air circuit 32. One end of the negative pressure air circuit 32 is connected to the negative pressure drive mechanism, and the other end is connected to the suction port 41 of the collection component 1; the first deformation drive part 23 is integrally formed with the negative pressure component 3 and sealedly connected, and the negative pressure component 3 indirectly applies negative pressure to the collection component 1 through the first deformation drive part 23.

[0136] In one embodiment of the present application, the first deformation driving part 23 is integrally formed with the suction port 41 of the collection component 1 and is sealedly connected.

[0137] In this embodiment, the negative pressure drive mechanism is connected to the suction port 41 of the collecting component 1 through the negative pressure air path 32. The first deformation drive part 23 is integrally formed and sealedly connected to the suction port 41 of the collecting component 1. The negative pressure drive mechanism can indirectly apply negative pressure to the collecting component 1 through the first deformation drive part 23 to allow milk to flow out of the user's mammary gland and prevent the milk from being sucked into the negative pressure component 3, causing milk contamination or circuit damage.

[0138] In one embodiment of the present application, the first deformation driving part 23 is a diaphragm or an airbag.

[0139] In this embodiment, the first deformation driving part 23 can be made of a deformable elastic material, such as a diaphragm or airbag made of silicone or rubber material. Through the pump pressure of the negative pressure driving component 31 in the negative pressure component 3 and its own deformation, the negative pressure is indirectly applied to the collecting component 1, and finally the negative pressure is applied to the user's breast, helping the user to discharge milk and flow it into the milk storage container 12 for temporary storage.

[0140] In one embodiment of the present application, the breast pump 100 further includes a diaphragm bracket 21 , which is disposed in the collecting assembly 1 and communicates with the collecting assembly 1 , and the first deformation driving portion 23 is sandwiched between the diaphragm bracket 21 and the housing 33 .

[0141] In this embodiment, the breast pump 100 also includes a diaphragm bracket 21, which is made of a hard material, such as hard plastic. The diaphragm bracket 21 is bowl-shaped, and the bottom opening of the diaphragm bracket 21 is connected to the collecting component 1. The first deformation driving part 23 is clamped between the top bowl mouth of the diaphragm bracket 21 and the outer shell 33 to limit the movement space and deformation range of the first deformation driving part 23. The first liquid component driving part indirectly applies negative pressure to the collecting component 1 through the diaphragm bracket 21, and finally applies negative pressure to the user's breast, helping the user to discharge milk and flow it into the milk storage container 12 for temporary storage.

[0142] In one example, the first deformation driving part 23 is integrally formed on a hard diaphragm cover 4 so that a deformable chamber is formed between the first deformation driving part 23 and the diaphragm cover 4. The first deformation driving part 23 can be deformed and reciprocated under the drive of the negative pressure air pump, which can cause the air pressure inside the breast shield 11 to change, thereby sucking breast milk into the milk storage container 12. The diaphragm cover 4 is detachably installed on the main unit and is connected to the air pump air path in the main unit.

[0143] In one embodiment of the present application, the breast pump 100 further includes a second deformation drive unit 24, which is disposed in the collection component 1 or connected to the first deformation drive unit 23, and the negative pressure component 3 applies negative pressure to the collection component 1 through the first deformation drive unit 23 and the second deformation drive unit 24.

[0144] In this embodiment, the breast pump 100 is further provided with a second deformation driving unit 24, which is arranged in the collecting component 1 or directly or indirectly connected to the first deformation driving unit 23. The negative pressure component 3 applies negative pressure to the collecting component 1 through two layers of barrier driving parts, which can further increase the airtightness of the breast pump 100, reduce the probability of milk being sucked into the negative pressure component 3, and improve the service life of the breast pump 100.

[0145] In one embodiment of the present application, the first deformation driving portion 23 and the second deformation driving portion 24 are integrally formed and enclose a sealed space;

[0146] Alternatively, the first deformation driving portion 23 and the second deformation driving portion 24 are tightly connected.

[0147] In this embodiment, the first and second deformable drive parts 23 and 24 are integrally formed, and a sealed space can be enclosed between the first and second deformable drive parts 23 and 24. Negative pressure can be indirectly transferred from the second deformable drive part 24 to the first deformable drive part 23 through the sealed space, or directly transferred from the second deformable drive part 24 to the first deformable drive part 23 by tightly connecting the first and second deformable drive parts 23 and 24. This transfer of negative pressure ultimately applies negative pressure to the collection assembly 1, drawing milk from the mammary glands into the milk storage container 12 for temporary storage. Because the negative pressure assembly 3 indirectly applies negative pressure to the mobile phone through the first and second deformable drive parts 23 and 24, accidents in which milk is drawn into the negative pressure assembly 3 are reduced.

[0148] In one embodiment of the present application, the first deformation driving portion 23 and the second deformation driving portion 24 form a flat disc-shaped component.

[0149] In this embodiment, the first deformation driving part 23 and the second deformation driving part 24 form a flat disc-shaped component. The disc-shaped component can be a capsule with a space in the middle, or a double-layer tightly fitted component, which is not further limited here.

[0150] In one embodiment of the present application, the breast pump 100 further includes a connecting piece, the first deformable driving part 23 is sealedly connected to one end of the connecting piece, and the second deformable driving part 24 is sealedly connected to the other end of the connection, and the first deformable driving part 23 and the second deformable driving part 24 are enclosed to form a sealed space or a tight fit.

[0151] In this embodiment, the first and second deformable drive units 23 and 24 are integrally connected via an intermediate connector. A sealed space is formed between the first and second deformable drive units 23 and 24. Negative pressure is indirectly transferred from the second deformable drive unit 24 to the first deformable drive unit 23 via the sealed space, or directly transferred from the second deformable drive unit 24 to the first deformable drive unit 23 by the close connection between the first and second deformable drive units 23 and 24. This transfer of negative pressure ultimately applies negative pressure to the collection assembly 1, drawing milk from the mammary glands into the milk storage container 12 for temporary storage. Because the negative pressure assembly 3 indirectly applies negative pressure to the mobile phone through the first and second deformable drive units 23 and 24, accidents in which milk is drawn into the negative pressure assembly 3 are reduced.

[0152] In one embodiment of the present application, the connecting member is a support frame provided along the periphery of the first deformation driving portion 23 and the second deformation driving portion 24 , and the support frame defines the periphery shape of the first deformation driving portion 23 and the second deformation driving portion 24 .

[0153] In this embodiment, the support frame can be a structure that clamps the first deformation driving part 23 and the second deformation driving part 24 to form a seal; or the first deformation driving part 23 and the second deformation driving part 24 can be arranged at intervals, and the support frame is arranged between the two, and a sealing structure is formed between the support frame and the first deformation driving part 23 and the second deformation driving part 24; or the first deformation driving part 23 and the second deformation driving part 24 are integrally formed with the support frame to form a sealing structure, which is not further limited here.

[0154] In one embodiment of the present application, the second deformation driving portion 24 is a disposable sheet-shaped barrier deformation structure.

[0155] In this embodiment, since the second deformable drive unit 24 is located near the breast shield 11 and comes into direct contact with breast milk, the second deformable drive unit 24 can be configured as a disposable sheet-like barrier deformable structure. After a single use, it can be discarded and replaced with a new second deformable drive unit 24, reducing cleaning efforts and preventing the risk of water entering the breast pump 100 during cleaning, thereby extending the lifespan of the breast pump 100. This breast pump 100 can also be designed to be shared for emergency use, preventing cross-contamination by using a disposable second deformable drive unit 24.

[0156] In one example, the first deformation driving part 23 is integrally formed on the main body, or on the diaphragm cover 4 that can be detachably connected to the main body. The second deformation driving part 24 is provided outside the first deformation driving part 23. The first deformation driving part 23 can drive the second deformation driving part 24 to vibrate, causing the air pressure inside the breast shield 11 to change, thereby introducing milk from the breast into the milk storage container 12.

[0157] Preferably, the second deformable drive part 24 is a disposable film, which can be attached to the outside of the first deformable drive part 23 (the side close to the nipple channel). After milking is completed, the second deformable drive part 24 can be torn off or removed from the first deformable drive part 23 and discarded, which can avoid the need to clean the first deformable drive part 23 integrally formed on the main unit or the diaphragm cover 4. It is convenient and hygienic, and can also avoid damage to components such as the internal circuit of the main unit due to cleaning.

[0158] Preferably, the second deformation driving unit 24 can be integrally formed with the milk bowl or the tee (or the breast shield 11). Alternatively, the second deformation driving unit 24 can be a separate, detachable structure that can be deformed by the deformation of the first deformation driving unit 23 while preventing the first deformation driving unit 23 from directly contacting the milk. When the main unit is separated from the milk bowl, the first deformation driving unit 23 and the second deformation driving unit 24 are separated together.

[0159] The present application also proposes another breast pump 100, referring to Figures 11 to 13. In the embodiment of the present application, the breast pump 100 includes a collecting component 1, a negative pressure component 3 and a liquid barrier driver 2. 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 store milk; the negative pressure component 3 is connected to the collecting component 1 and indirectly applies negative pressure to the collecting component 1; the liquid barrier driver 2 is provided in the collecting component 1, and the liquid barrier driver 2 includes a first deformable driver 23 and a second deformable driver 24. The first deformable driver 23 and the second deformable driver 24 form a double-layer drive structure. The negative pressure component 3 indirectly applies negative pressure to the collecting component 1 through the first deformable driver 23 and the second deformable driver 24.

[0160] In this embodiment, the collection assembly 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. The milk storage container 12 can be directly connected to the breast shield 11, connected via a short tube, or the milk bowl can surround the breast shield 11 to form a separate wearable unit. The two can be integral or detachable, or the milk bowl or milk bottle can be connected to a housing separately, but a channel between the two allows breast milk to flow from the breast shield 11 into the milk storage container 12. The breast shield 11 is designed to fit the user's breast and has a funnel or hemispherical shape that conforms to the breast. To enhance the user experience, the breast shield 11 is made of a skin-friendly and soft material, such as silicone or latex, which is comfortable and less likely to cause skin allergies or other problems. The negative pressure assembly 3 indirectly applies negative pressure to the collection assembly 1 via the liquid barrier driver 2, causing the collection assembly 1 to compress the breast, helping the user drain milk from the breast and transfer it into the milk storage container 12 for temporary storage. The power structure used to generate negative pressure in the negative pressure assembly 3 includes, but is not limited to, a piezoelectric pump, a diaphragm pump, a hydraulic pump, or a mechanical pump. This negative pressure can be transmitted to a liquid barrier such as a diaphragm or an airbag, indirectly creating a negative pressure inside the breast shield 11. This negative pressure draws breast milk into the milk storage container 12 for storage. The liquid barrier driver 2 can be a deformable structure such as a diaphragm or an airbag. The negative pressure assembly 3 indirectly applies negative pressure to the collection assembly 1 through the deformation of the liquid barrier driver 2, ultimately applying negative pressure to the user's breast, drawing milk into the milk storage container 12 for temporary storage. The liquid barrier driver 2 includes a first deformable driver portion 23 and a second deformable driver portion 24. The double-layer liquid barrier driver 2 can improve the airtightness of the breast pump 100. When one layer fails unexpectedly, the other layer of the liquid barrier driver 2 serves as insurance to prevent milk from being sucked into the negative pressure assembly 3, thereby extending the service life of the breast pump 100.

[0161] The breast pump 100 proposed in the technical solution of the present application includes a collection component 1, a negative pressure component 3 and a liquid barrier driver 2. The collection component 1 includes a breast shield 11 and a milk storage container 12. The liquid barrier driver 2 is arranged on the collection component 1. When the user uses it, the breast shield 11 is attached to the breast. The negative pressure component 3 indirectly applies negative pressure to the collection component 1 through the liquid barrier driver 2, so that milk can be sucked out of the user's breast and then flow into the milk storage container 12 for temporary storage. The liquid barrier driver 2 includes a first deformable driver 23 and a second deformable driver 24, which is more effective and can reduce the occurrence of milk 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.

[0162] In one embodiment of the present application, the first deformation driving portion 23 and the second deformation driving portion 24 are integrally formed and enclose a sealed space;

[0163] Alternatively, the first deformation driving portion 23 and the second deformation driving portion 24 are tightly connected.

[0164] In this embodiment, the first and second deformable drive parts 23 and 24 are integrally formed, and a sealed space can be enclosed between the first and second deformable drive parts 23 and 24. Negative pressure can be indirectly transferred from the second deformable drive part 24 to the first deformable drive part 23 through the sealed space, or directly transferred from the second deformable drive part 24 to the first deformable drive part 23 by tightly connecting the first and second deformable drive parts 23 and 24. This transfer of negative pressure ultimately applies negative pressure to the collection assembly 1, drawing milk from the mammary glands into the milk storage container 12 for temporary storage. Because the negative pressure assembly 3 indirectly applies negative pressure to the mobile phone through the first and second deformable drive parts 23 and 24, accidents in which milk is drawn into the negative pressure assembly 3 are reduced.

[0165] In one embodiment of the present application, the first deformation driving portion 23 and the second deformation driving portion 24 form a flat disc-shaped component.

[0166] In this embodiment, the first deformation driving part 23 and the second deformation driving part 24 form a flat disc-shaped component. The disc-shaped component can be a capsule with a space in the middle, or a double-layer tightly fitted component, which is not further limited here.

[0167] In one embodiment of the present application, the liquid barrier driving member 2 also includes a connecting member, the first deformation driving part 23 is sealedly connected to one end of the connecting member, and the second deformation driving part 24 is sealedly connected to the other end of the connection. The first deformation driving part 23 and the second deformation driving part 24 are enclosed to form a sealed space or tightly fit.

[0168] In this embodiment, the first and second deformable drive units 23 and 24 are integrally connected via an intermediate connector. A sealed space is formed between the first and second deformable drive units 23 and 24. Negative pressure is indirectly transferred from the second deformable drive unit 24 to the first deformable drive unit 23 via the sealed space, or directly transferred from the second deformable drive unit 24 to the first deformable drive unit 23 by the close connection between the first and second deformable drive units 23 and 24. This transfer of negative pressure ultimately applies negative pressure to the collection assembly 1, drawing milk from the mammary glands into the milk storage container 12 for temporary storage. Because the negative pressure assembly 3 indirectly applies negative pressure to the mobile phone through the first and second deformable drive units 23 and 24, accidents in which milk is drawn into the negative pressure assembly 3 are reduced.

[0169] In one embodiment of the present application, the connecting member is a support frame provided along the periphery of the first deformation driving portion 23 and the second deformation driving portion 24 , and the support frame defines the periphery shape of the first deformation driving portion 23 and the second deformation driving portion 24 .

[0170] In this embodiment, the support frame can be a structure that clamps the first deformation driving part 23 and the second deformation driving part 24 to form a seal; or the first deformation driving part 23 and the second deformation driving part 24 can be arranged at intervals, and the support frame is arranged between the two, and a sealing structure is formed between the support frame and the first deformation driving part 23 and the second deformation driving part 24; or the first deformation driving part 23 and the second deformation driving part 24 are integrally formed with the support frame to form a sealing structure, which is not further limited here.

[0171] In one embodiment of the present application, the support frame is made of a hard material.

[0172] In this embodiment, the support frame is made of a hard material, such as hard plastic, which can better clamp or connect the first deformation driving part 23 and the second deformation driving part 24 to form a sealing structure and be installed at the required installation position.

[0173] In one embodiment of the present application, the first deformation driving part 23 and the second deformation driving part 24 are independent of each other. When the breast pump 100 is assembled, the first deformation driving part 23 and the second deformation driving part 24 enclose a sealed space or fit tightly together.

[0174] In this embodiment, the first deformation driving unit 23 and the second deformation driving unit 24 are two independent components. One can be provided on the breast shield 11 and the other on the milk storage container 12. When the breast shield 11 and the milk storage container 12 are connected, the first deformation driving unit 23 and the second deformation driving unit 24 enclose a sealed space or fit tightly together to transmit negative pressure. Alternatively, one can be provided on the milk storage container 12 and the other on the negative pressure assembly 3. When the negative pressure assembly 3 and the milk storage container 12 are connected, the first deformation driving unit 23 and the second deformation driving unit 24 enclose a sealed space or fit tightly together to transmit negative pressure.

[0175] In one embodiment of the present application, the first deformation driving portion 23 is closer to the breast shield 11 than the second deformation driving portion 24. The first deformation driving portion 23 includes a first side close to the breast shield 11 and a second side close to the second deformation driving portion 24. The second deformation driving portion 24 includes a third side close to the second side of the first deformation driving portion 23 and a fourth side away from the breast shield 11. The second side is closely fitted to or spaced apart from the third side.

[0176] In this embodiment, the first deformation drive part 23 is arranged close to the breast shield 11, and the second deformation drive part 24 is arranged close to the first deformation drive part 23. The first deformation drive part 23 and the second deformation drive part 24 are tightly fitted or spaced apart to form a sealed space to transfer negative pressure from the second deformation drive part 24 to the first deformation drive part 23, and finally to the breast shield 11.

[0177] In one embodiment of the present application, the first deformation driving portion 23 is a disposable sheet-shaped barrier deformation structure.

[0178] In this embodiment, since the first deformable actuator 23 is positioned close to the breast shield 11 and comes into direct contact with breast milk, the first deformable actuator 23 can be configured as a disposable sheet-like barrier deformable structure. After a single use, it can be discarded and replaced with a new first deformable actuator 23, reducing cleaning efforts and preventing the risk of water entering the breast pump 100 during cleaning, thereby extending the lifespan of the breast pump 100. This breast pump 100 can also be designed to be shared for emergency use, preventing cross-contamination by using a disposable first deformable actuator 23.

[0179] In one embodiment of the present application, the liquid barrier driving member 2 is integrally formed with the milk storage container 12 and is sealedly connected to the milk storage container 12 to separate the breast pump 100 into two gas-liquid separated parts.

[0180] In this embodiment, the liquid barrier driver 2 is integrally formed with the milk storage container 12 and sealed, dividing the breast pump 100 into two gas-liquid separations. One section allows milk to flow, ultimately into the milk storage container 12 for temporary storage. The other section allows the negative pressure assembly 3 to apply negative pressure to the liquid barrier driver 2, indirectly applying negative pressure to the space within the breast shield 11 and milk storage container 12. Ultimately, this negative pressure is applied to the user's breast, helping the user express milk from the mammary gland. The liquid barrier driver 2 prevents milk from being drawn into the air path of the negative pressure assembly 3, thereby preventing milk contamination or short-circuiting the negative pressure assembly 3.

[0181] In one embodiment of the present application, the collecting assembly 1 further comprises a three-way assembly 13 having three openings connected to one another, wherein the first opening is connected to the breast shield 11, the second opening is connected to the negative pressure assembly 3, and the third opening is connected to the milk storage container 12. The liquid barrier driving component 2 is disposed in the three-way assembly 13 and is integrally formed with the three-way assembly 13 and sealedly connected thereto. The liquid barrier driving component 2 separates the three-way assembly 13 into two parts for gas-liquid separation, and the negative pressure assembly 3 indirectly applies negative pressure to the three-way assembly 13 via the liquid barrier driving component 2.

[0182] In this embodiment, the collection assembly 1 also includes a three-way assembly 13, which includes a first opening, a second opening, and a third opening that communicate with each other. The first opening is for communication with the breast shield 11, the second opening is for communication with the negative pressure assembly 3, and the third opening is for communication with the milk storage container 12. The liquid barrier driver 2, which can be a diaphragm or airbag structure, is integrally formed within the three-way assembly 13 and sealed therewith. The negative pressure assembly 3 and the liquid barrier driver 2 apply negative pressure to the three-way assembly 13, which in turn applies negative pressure to the collection assembly 1, ultimately applying negative pressure to the user's breast, helping the user express milk from the mammary gland. The milk then flows through the breast shield 11 into the milk storage container 12 for temporary storage. The liquid barrier driver 2 disposed in the three-way assembly 13 prevents milk from being drawn into the negative pressure assembly 3, thereby preventing milk contamination or short circuiting of the negative pressure assembly 3.

[0183] In one embodiment of the present application, the breast shield 11 includes a flange 111 and a nipple receiving portion 112. The nipple receiving portion 112 has openings at both ends and is connected thereto. The flange 111 is connected to an opening of the nipple receiving portion 112. The flange 111 is used to abut against the breast. The liquid barrier driver 2 is integrally formed with the flange 111 and is sealed therewith. The negative pressure assembly 3 indirectly applies negative pressure to the flange 111 via the liquid barrier driver 2.

[0184] Alternatively, the liquid barrier driver 2 is disposed at another opening of the nipple accommodating portion 112 and is sealedly connected to the other opening of the nipple accommodating portion 112 , and the negative pressure component 3 indirectly applies negative pressure to the nipple accommodating portion 112 through the liquid barrier driver 2 .

[0185] In this embodiment, the breast shield 11 includes a flange 111 and a nipple receiving portion 112. The nipple receiving portion 112 is open at both ends and is through-hole, for accommodating the nipple. The nipple receiving portion 112 can be made of a rigid material, such as plastic, metal tube, glass tube, etc., or a flexible or semi-flexible material, such as rubber or silicone, without specific limitation. The flange 111 is made of a flexible material, such as rubber or silicone. When negative pressure is applied to the flange 111, the flange 111 deforms, transmitting the negative pressure to the user's breast, further improving milk ejection efficiency. A liquid barrier driver 2 is integrally formed with the flange 111. The negative pressure assembly 3 applies negative pressure to the liquid barrier driver 2, thereby applying negative pressure to the flange 111, ultimately applying negative pressure to the user's breast, helping to express milk from the mammary gland. The milk then flows through the breast shield 11 into the milk storage container 12 for temporary storage. The liquid barrier driver 2 is arranged on the flange 111, and the air path of the negative pressure assembly 3 is not connected to the flange 111 and / or the nipple receiving portion 112, so there is no risk of contaminating milk or damaging the circuit.

[0186] In one example, the liquid barrier driver 2 is positioned at another opening of the nipple receiving portion 112, and the negative pressure assembly 3 indirectly applies negative pressure to the liquid barrier driver 2. The liquid barrier driver 2 is made of an elastically deformable material and can deform, thereby applying negative pressure to the nipple receiving portion 112, and ultimately to the user's breast, helping to express milk from the mammary gland. The milk flows through the breast shield 11 into the milk storage container 12 for temporary storage. The liquid barrier driver 2 is positioned at another opening of the nipple receiving portion 112, allowing milk to flow directly from the nipple receiving portion 112 into the milk storage container 12. The liquid barrier driver 2 prevents milk from being drawn into the negative pressure assembly 3, potentially contaminating the milk or damaging the circuitry.

[0187] In one example, the collection assembly 1 includes a breast shield 11, which includes a flange 111 that fits against the breast, a nipple receiving portion 112 that accommodates the nipple, and a milk storage container 12 in fluid communication with the nipple receiving portion 112. The two components can be integral or detachable. Preferably, a first deformable drive portion 23 and a second deformable drive portion 24 are integrally formed at the end of the flange 111. The first deformable drive portion 23 includes a side proximal to the milk and a side distal to the milk, and the second deformable drive portion 24 includes a side proximal to the first deformable drive portion 23 and a side proximal to the air path. The first deformable drive portion 23 and the second deformable drive portion 24 are tightly fitted together, or a negative pressure chamber is formed therebetween. An air pump intermittently draws air from the air inlet, driving the first deformable drive portion 23 and the second deformable drive portion 24 to reciprocate. The negative pressure drive assembly 31 includes an air pump, which applies negative pressure through the negative pressure air hole, causing the first deformation drive part 23 and the second deformation drive part 24 to deform and reciprocate, causing negative pressure to be generated in the flange 111, and guiding milk from the breast milk to the milk bowl.

[0188] In other examples, the first deformation driving part 23 is integrated on the side wall of the channel of the milk bowl or the diaphragm is integrally formed at the end of the nipple channel; the second deformation driving part 24 is integrated on the main unit and closes the negative pressure suction port.

[0189] The present application also proposes a breast pump 100, referring to Figures 14 to 16. In the embodiment of the present application, the breast pump 100 includes a collecting component 1, a negative pressure component 3, a liquid barrier driver 2 and a leakage detection unit 6. One side of the collecting component 1 is used to fit the breast, and the other side is used to collect milk; the negative pressure component 3 is connected to the collecting component 1 and indirectly applies negative pressure to the collecting component 1; the liquid barrier driver 2 is arranged between the collecting component 1 and the negative pressure component 3, and the negative pressure component 3 applies negative pressure to the collecting component 1 through the liquid barrier driver 2; the leakage detection unit 6 is arranged between the negative pressure component 3 and the liquid barrier driver 2, and is used to detect whether milk leaks into the negative pressure component 3.

[0190] In this embodiment, one side of the collection assembly 1 is designed to conform to the breast and should be made of a soft, skin-friendly material, such as silicone or latex, for increased comfort and less risk of skin allergies. The other side is used to collect breast milk and can be constructed using a bowl, bag, or bottle, without further limitation. The liquid barrier actuator 2 can be a diaphragm or airbag, and is integrally formed with the collection assembly 1, preventing disassembly and misalignment that could cause milk leakage or backflow. The collection assembly 1 includes a breast shield 11 and a milk storage container 12. The milk storage container 12 can be a bag, bottle, or bowl. The milk storage container 12 can be connected directly to the breast shield 11, connected via a short tube, or with the bowl surrounding the breast shield 11 to form a separate wearable unit. The two can be integral or detachable, or the bowl or bottle can be connected separately to a housing, with a passageway between them, allowing breast milk to flow from the breast shield 11 into the milk storage container 12. Breast shield 11 is designed to fit the user's breast and is shaped like a funnel or hemisphere to conform to the breast. To enhance the user experience, breast shield 11 is made of a soft, skin-friendly material, such as silicone or latex, which is comfortable and less likely to cause skin allergies. Negative pressure assembly 3 indirectly applies negative pressure to collection assembly 1 via liquid barrier driver 2, causing collection assembly 1 to compress the breast, helping the user drain milk from the breast and allowing it to flow into collection assembly 1 for temporary storage. The power structure used to generate negative pressure in negative pressure assembly 3 includes, but is not limited to, a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, and the like. This negative pressure can be indirectly generated by transmitting it to a liquid barrier, such as a diaphragm or airbag, to draw breast milk into collection assembly 1 for storage. A leakage detection component is provided on the negative pressure component 3 to detect whether milk leaks into the negative pressure component 3 to prevent the circuit inside the negative pressure component 3 from short-circuiting and failing. The leakage detection component can be a detection electrode, a temperature sensor, a liquid level sensor, etc.

[0191] The technical solution of the present application includes a collection component 1, a negative pressure component 3, a liquid barrier driver 2, and a leakage detection unit 6. The negative pressure component 3 indirectly applies negative pressure to the collection component 1 via the liquid barrier driver 2 disposed between the collection component 1 and the negative pressure component 3. One side of the collection component 1 is attached to the breast, transmitting the negative pressure applied by the negative pressure component 3 to the user's breast, sucking milk from the mammary gland and temporarily storing it within the collection component 1. The leakage detection unit 6 is provided on the negative pressure component 3 to detect whether milk is leaking into the negative pressure component 3, thereby promptly rescuing the circuit components within the negative pressure component 3 and preventing circuit short circuits caused by liquid ingress.

[0192] In one embodiment of the present application, the breast pump 100 further includes a housing 33 , and the negative pressure assembly 3 is at least partially disposed within the housing 33 .

[0193] In this embodiment, the breast pump 100 further includes a housing 33. Housing 33 should be made of a rigid material, such as rigid plastic or a metal material such as an aluminum alloy or titanium alloy, to protect the internal negative pressure assembly 3 and other components, including the power supply. The shape of housing 33 can be selected based on actual needs and is not further limited herein. Negative pressure assembly 3 can be entirely disposed within housing 33, communicating with collection assembly 1 through negative pressure vents defined in housing 33 to apply negative pressure to collection assembly 1. Alternatively, negative pressure assembly 3 can be partially exposed within housing 33, communicating with collection assembly 1 through the exposed negative pressure vents 32 to apply negative pressure to collection assembly 1.

[0194] In one embodiment of the present application, the leakage detection unit 6 includes a detection electrode, which is disposed on a side of the liquid barrier driver 2 close to the negative pressure assembly 3 .

[0195] In this embodiment, leakage of the breast pump 100 is detected by a detection electrode. The detection electrode is arranged on the side of the liquid barrier driver 2 close to the negative pressure assembly 3. If the detection electrode is connected, it means that the seal of the liquid barrier driver 2 has failed and leakage has occurred. In this case, it is necessary to stop the operation of the negative pressure assembly 3, check and replace the liquid barrier driver 2 with a better sealing performance to prevent the negative pressure assembly 3 from sucking in more lotion and causing a short circuit of the negative pressure assembly 3.

[0196] In one embodiment of the present application, the negative pressure component 3 is provided with a suction port 41 , the housing 33 is sealedly connected to the liquid barrier driver 2 to form a sealing surface, and the detection electrode is provided on the side of the sealing surface.

[0197] In this embodiment, the negative pressure component 3 is provided with an air suction port, and the liquid barrier driver 2 is sealedly connected to the housing 33, dividing the breast pump 100 into two parts separated by gas and liquid. A sealing surface is formed between the liquid barrier driver 2 and the housing 33, and a detection electrode is provided on the side of the sealing surface. This can more promptly detect whether the liquid barrier driver 2 has leaked, thereby preventing the negative pressure component 3 from sucking in more lotion and causing a short circuit in the negative pressure component 3.

[0198] In one embodiment of the present application, the distal end of the detection electrode is lower than the suction port 41.

[0199] In this embodiment, in order to detect milk leakage earlier, the distal end of the detection electrode is set lower than the suction port 41, so that the leakage can be sensed before the liquid enters the air path. This can reserve more time for the machine or the user to shut down the machine and avoid the liquid inertia causing the liquid to enter the machine, causing milk contamination and machine damage.

[0200] In one embodiment of the present application, the detection electrodes are provided on all side surfaces of the sealing surface.

[0201] In this embodiment, the detection electrodes are provided on all sides of the sealing surface, and leakage detection can be performed on all sides of the sealing surface at the same time to prevent leakage from occurring at a certain part of the sealing surface. However, if no detection electrodes are provided here, a certain amount of milk needs to accumulate before it can be detected by the nearby detection electrodes, causing liquid to enter the interior of the machine, resulting in milk contamination and machine damage.

[0202] In one embodiment of the present application, the leakage detection unit 6 further includes a capacitive sensor, which is disposed on a side of the liquid barrier driver 2 close to the negative pressure assembly 3 .

[0203] In this embodiment, since the capacitance of milk and air is different, the capacitive sensor can detect the capacitance change in the space on the side of the liquid barrier driver 2 close to the negative pressure component 3, and then determine whether the liquid barrier driver 2 is leaking.

[0204] In one embodiment of the present application, the leakage detection unit 6 further includes a pressure sensor, which is provided on a side of the liquid barrier driver 2 close to the negative pressure assembly 3 or a side close to the breast shield 11 .

[0205] In this embodiment, due to the different masses of milk and air, the pressure sensor can determine whether the liquid barrier driver 2 is leaking by detecting the weight change of the space on the side of the liquid barrier driver 2 close to the negative pressure component 3.

[0206] In one embodiment of the present application, the negative pressure component 3 includes a negative pressure drive component 31 and a negative pressure air circuit 32. One end of the negative pressure air circuit 32 is connected to the negative pressure drive component 31, and the other end of the negative pressure air circuit 32 is connected to the collection component 1. The negative pressure air circuit 32 has a liquid seepage limit position, and the leakage detection unit 6 is a detection electrode, which is arranged at the liquid seepage limit position of the inner wall of the negative pressure air circuit 32.

[0207] In this embodiment, the negative pressure drive component 31 is connected to one end of the negative pressure air circuit 32 and the other end is connected to the collection component 1 to apply negative pressure to the collection component 1. The detection electrode is arranged on the negative pressure air circuit 32. A seepage limit position, that is, a dangerous position, is provided on the negative pressure air circuit 32. When the milk exceeds this position, it will pose a threat to the circuit components inside the negative pressure component 3. When the milk reaches the position of the detection electrode, the milk acts as a conductor and can connect the detection electrode to form a loop, thereby issuing an alarm or indicator light to the user to remind the user that the milk leakage has reached the limit position.

[0208] In one embodiment of the present application, the leakage detection unit 6 further includes a liquid level detection sensor, which is disposed in the negative pressure gas circuit 32 and is used to detect whether there is liquid in the negative pressure gas circuit 32 .

[0209] In this embodiment, a liquid level detection sensor is provided in the negative pressure air circuit 32. By detecting whether there is liquid in the negative pressure air circuit 32, and further detecting whether milk has been sucked into the negative pressure air circuit 32, it is possible to detect earlier whether milk has leaked into the negative pressure air circuit 32, thereby preventing milk from being sucked into the negative pressure component 3, causing a short circuit in the negative pressure component 3, and causing the breast pump 100 to fail.

[0210] In one embodiment of the present application, the middle position of the negative pressure air circuit 32 is recessed inward to form a first cavity and a second cavity that are connected. The second cavity is connected to the negative pressure component 3, and the first cavity is connected to the collecting component 1. The cross-sectional area of ​​the second cavity gradually decreases away from the negative pressure component 3, and the liquid level detection sensor is arranged on the cavity wall of the first cavity.

[0211] In this embodiment, the middle position of the negative pressure air path 32 is recessed inward to form two connected cavities, the first cavity is connected to the collecting component 1, and the second cavity is connected to the negative pressure component 3. The cross-sectional area of ​​the second cavity gradually decreases away from the negative pressure component 3. In the case of the same volume of leaked milk, the amplitude of the liquid level change in the second cavity is greater, which indirectly improves the detection sensitivity of the liquid level detection sensor, and can more promptly detect that the milk has leaked into the negative pressure air path 32, preventing the milk from being sucked into the negative pressure component 3, causing a short circuit in the negative pressure component 3, resulting in milk contamination or failure of the breast pump 100.

[0212] In one embodiment of the present application, the leakage detection unit 6 is a photoelectric sensor assembly, which includes an emitter and a receiver, which are respectively arranged on two opposite sides of the inner wall of the negative pressure air path 32. The emitter is used to emit detection light, and the receiver is used to receive the detection light to detect whether there are milk droplets entering the negative pressure assembly 3.

[0213] In this embodiment, the emitter and receiver of the photoelectric sensor assembly are arranged on opposite sides of the inner wall of the negative pressure air path 32. When milk droplets are sucked into the negative pressure assembly 3, they block the emitter of the photoelectric sensor assembly while moving within the negative pressure air path 32, so that the receiver cannot receive the light from the emitter. This indicates that milk droplets have entered the negative pressure assembly 3 through the negative pressure air path 32. Timely discovery can prevent more milk from being sucked into the negative pressure assembly 3, which could cause a short circuit failure.

[0214] In one embodiment of the present application, the leakage detection unit 6 is a temperature sensor assembly, which is disposed on the inner wall of the negative pressure gas path 32 and is used to detect temperature changes inside the negative pressure gas path 32 .

[0215] In this embodiment, since the temperature of milk is higher than room temperature, a temperature sensor assembly is provided on the inner wall of the negative pressure air path 32. By detecting the temperature change inside the negative pressure air path 32, it is determined whether milk has entered the negative pressure air path 32. Timely detection can prevent the negative pressure assembly 3 from sucking in more milk, causing short circuit failure or milk contamination.

[0216] In one embodiment of the present application, the collection assembly 1 includes a breast shield 11, a milk storage container 12 and a tee assembly 13. The tee assembly 13 has three openings that are interconnected. The first opening is connected to the breast shield 11, the second opening is connected to the negative pressure assembly 3, and the third opening is connected to the milk storage container 12. The temperature sensor assembly is provided at the second opening.

[0217] In this embodiment, the collecting assembly 1 further includes a three-way assembly 13, which includes a first opening, a second opening, and a third opening that are interconnected. The first opening is used to communicate with the breast shield 11, the second opening is used to communicate with the negative pressure assembly 3, and the third opening is used to communicate with the milk storage container 12. The temperature sensor assembly provided in the three-way assembly 13 can detect milk entering the negative pressure air path 32 earlier, thereby preventing milk contamination or a short circuit in the negative pressure assembly 3.

[0218] In one embodiment of the present application, the breast pump 100 further includes a controller, which is electrically or communicatively connected to the negative pressure assembly 3 and the leakage detection unit 6, respectively, to receive a leakage signal from the leakage detection unit 6 and control the negative pressure assembly 3 to stop operating.

[0219] In this embodiment, the breast pump 100 further includes a controller, which is electrically or communicatively connected to the negative pressure assembly 3 and the leakage detection unit 6. When the leakage detection unit 6 detects milk leakage, it transmits a leakage signal to the controller. The controller receives the leakage signal and determines the leakage signal. If the leakage signal indicates leakage, the controller controls the negative pressure assembly 3 to stop operating to prevent the circuit board in the negative pressure assembly 3 from being burned, which would cause the entire breast pump 100 to fail.

[0220] In one embodiment of the present application, the breast pump 100 further includes an alarm, and the controller is electrically connected or communicatively connected to the alarm to control the alarm to sound an alarm.

[0221] In this embodiment, the breast pump 100 also includes an alarm. When the leakage detection unit 6 detects milk leakage, it will transmit a leakage signal to the controller. The controller receives the leakage signal and judges the leakage signal. If the leakage signal indicates that a leakage has occurred, the controller controls the alarm to sound an alarm to remind the user to pay attention to the leakage problem of the breast pump 100, manually cut off the power supply in time, and open the negative pressure component 3 for processing to prevent further damage to the negative pressure component 3.

[0222] In one embodiment of the present application, the breast pump 100 further includes an indicator light, and the controller is electrically or communicatively connected to the indicator light.

[0223] In this embodiment, the breast pump 100 further includes an indicator light. When the leakage detection unit 6 detects milk leakage, it transmits a leakage signal to the controller. The controller receives the leakage signal and determines the leakage signal. If the leakage signal indicates leakage, the controller controls the indicator light to emit an indicator light to warn the user, so as to remind the user to pay attention to the leakage problem of the breast pump 100, manually cut off the power supply in time, and open the negative pressure component 3 for processing to prevent further damage to the negative pressure component 3.

[0224] This application also proposes a detection feedback method, which is applied to the breast pump as described above, comprising the following steps:

[0225] Step S1: the leakage detection unit detects leakage, converts the leakage signal into an electrical signal, and transmits the electrical signal to the controller;

[0226] Step S2: The controller determines whether the electrical signal exceeds a set threshold;

[0227] Step S3: If it does not exceed, the breast pump continues to work; if it exceeds, the controller controls the alarm to sound an alarm, and / or controls the indicator light to give a warning, and / or controls the negative pressure component to stop.

[0228] In this embodiment, the leakage detection unit 6 first detects that the breast pump 100 has leaked, and is able to convert the leakage signal into an electrical signal, which is then transmitted to the controller. The controller receives the electrical signal and determines whether the amount of leakage exceeds a set threshold value based on the electrical signal. If the set threshold value is exceeded, it indicates that a large leakage has occurred. At this time, the controller controls the alarm to sound an alarm or the indicator light to indicate a warning, reminding the user that the breast pump 100 has leaked milk and that the user needs to manually stop the breast pump 100. Alternatively, while controlling the alarm to sound an alarm or the indicator light to indicate a warning, the controller can also control the negative pressure component 3 of the breast pump 100 to stop operating in time to prevent further leakage.

[0229] The present application also proposes a breast pump 100, comprising a collecting component 1, a negative pressure component 3, a liquid barrier driver 2 and a leakage detection unit 6. One side of the collecting component 1 is used to fit against the breast, and the other side is used to collect milk; the negative pressure component 3 is connected to the collecting component 1 and indirectly applies negative pressure to the collecting component 1; the liquid barrier driver 2 is arranged between the collecting component 1 and the negative pressure component 3, and the negative pressure component 3 applies negative pressure to the collecting component 1 through the liquid barrier driver 2; the leakage detection unit 6 is arranged in a sealed negative pressure cavity formed between the liquid barrier driver 2 and the negative pressure component 3 to detect whether the sealed negative pressure cavity is leaking or liquid has penetrated.

[0230] In this embodiment, the sealed negative pressure chamber formed between the liquid barrier driving member 2 and the negative pressure assembly 3 can be used to detect whether there is air leakage or liquid infiltration in the sealed negative pressure chamber, thereby detecting whether the breast pump 100 is leaking.

[0231] In one embodiment, the collection assembly 1 includes a breast shield 11 and a milk storage container 12. The breast shield 11 includes a flange 111 that fits against the breast and receives breast milk, and an outlet for transferring breast milk into the milk storage container 12. The milk storage container 12 can store breast milk alone or, together with the breast shield 11, form a housing for storing breast milk. The collection assembly 1 is provided with a negative pressure vent, which, under the action of a liquid barrier driver 2 (an elastically deformable member such as a suction diaphragm or bladder), changes the internal pressure of the milk extraction assembly to guide the breast milk into the milk storage container 12. The negative pressure assembly 3 includes a negative pressure pump, a negative pressure air path 32, and a negative pressure deformation chamber 5. The negative pressure deformation chamber 5 is provided with a suction port, which allows the liquid barrier driver 2 to reciprocate, generating negative pressure inside the breast shield 11 and guiding the breast milk into the milk storage container 12. The negative pressure deformation chamber 5 comprises at least a portion of a suction diaphragm sealed against the deformation chamber suction port of the negative pressure air circuit 32 to form a chamber. When the negative pressure pump intermittently draws air, the negative pressure deformation chamber 5 deforms, generating negative pressure within the breast shield 11 to guide breast milk into the milk storage container 12. A leakage detection component is at least partially disposed within the negative pressure deformation chamber 5 and is capable of detecting air or liquid leakage from the negative pressure deformation chamber 5 and transmitting a signal to the host control circuit. The leakage detection component can be one or more of a detection electrode, a detection capacitor, an optical sensor, or a pressure sensor. The leakage detection unit 6 can also be integrated within the liquid barrier driver 2, near the negative pressure deformation chamber 5, such as an electrode or capacitor coating. The liquid barrier driver 2 is sealed between the diaphragm support 21 and the milk bowl. The suction port of the negative pressure deformation chamber 5 communicates with the negative pressure deformation chamber 5 via the negative pressure port on the milk bowl.

[0232] In another embodiment, a leakage detection unit 6 is disposed within the sealed cavity formed by the liquid barrier driver 2 and the main unit, or is capable of remotely detecting air or liquid leaks within the sealed cavity formed by the liquid barrier driver 2 and the main unit. The leakage detection component may be one or more of a detection electrode, a detection capacitor, an optical sensor, or a pressure sensor. The leakage detection unit 6 is electrically connected to the main unit control circuit board via a circuit to provide feedback to the control circuit board. When the leakage detection unit 6 is a detection electrode, the lowest end of the detection electrode is lower than the air inlet of the negative pressure deformation chamber 5, allowing for early detection of leakage before the leaked liquid enters the negative pressure air path 32. When the leakage detection unit 6 is a pressure sensor, it can sense pressure changes within the negative pressure deformation chamber 5. When a gas or liquid leak occurs, the pressure sensor can detect the difference between the pressure change within the negative pressure deformation chamber 5 and the pressure in a non-leakage state, thereby determining whether the breast pump 100 is currently leaking.

[0233] In another embodiment, the negative pressure deformation chamber 5 can be formed by the main body housing 33 and the diaphragm bracket 21 of the flange 111 to seal the liquid barrier driving member 2; the negative pressure deformation chamber 5 can also be formed by a separate liquid barrier driving member 2 and the diaphragm bracket 21 of the flange 111 to seal the liquid barrier driving member 2;

[0234] Preferably, the negative pressure air inlet is arranged at the upper part of the negative pressure deformation chamber 5, the detection electrode is at least partially arranged in the negative pressure deformation chamber 5, and the lowest position of the detection electrode is located below the negative pressure air inlet.

[0235] When air or liquid leakage is detected in the negative pressure deformation chamber 5, the control circuit sends an alarm or a shutdown signal to minimize the possibility of milk seeping into the pump to contaminate the milk or damage the host circuit.

[0236] The leakage detection unit 6 can also be a non-contact sensor, such as an optical sensor, a camera or an infrared sensor, which can identify when milk leaks out of the negative pressure deformation chamber 5 and immediately feedback a shutdown or alarm signal to the host control circuit.

[0237] The leakage detection unit 6 can also be a non-contact capacitive sensor, which can be set outside the negative pressure deformation chamber 5, for example, on the side of the main body side wall close to the negative pressure deformation chamber 5. When seepage enters the negative pressure deformation chamber 5, it will cause the sensed capacitance to suddenly change. When the control circuit recognizes and determines the seepage state, it will feedback a shutdown or alarm signal to the control circuit.

All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
