Description

Nursing container, breast pump, method, device, medium, sealing structure, detection device and system TECHNICAL FIELD

[0001] The present application relates to the technical field of breast pumps, and in particular to a nursing container, a breast pump, a method, a device, a medium, a sealing structure, a detection device and a system. BACKGROUND

[0002] In modern life, breast pumps, as important auxiliary tools for maternal and infant care, have been widely used in the milk collection scene of lactating mothers. Postpartum mothers usually return to work a few weeks after giving birth, and a breast pump becomes an indispensable device to provide breast milk to the baby in time and relieve the swelling and pain of the breast when the breast milk secretion is more. The breast pump mainly extracts the breast milk in the breast through negative pressure, which facilitates the mother to collect and properly store the breast milk in a specific situation.

[0003] However, the existing breast pump still has many problems. During the entire breast pumping process, the use convenience of the breast pump is low, for example, there are problems such as inaccurate detection of the storage amount of milk, inconvenience to wear, lack of assembly convenience and sealing performance, etc. Therefore, how to improve the use convenience of the breast pump is a technical problem to be solved. SUMMARY

[0004] The present application provides a nursing container, a breast pump, a method, a device, a medium, a sealing structure, a detection device and a system, which aims to solve the technical problem of low use convenience of the breast pump in the prior art.

[0005] The present application provides a nursing container, which comprises:

[0006] a container body;

[0007] a damping device, which is at least partially arranged in the container body;

[0008] The damping device is used to weaken the oscillation of the milk liquid surface.

[0009] The damping device is installed in the container body of the nursing container. When the milk in the container body shakes, the damping device weakens the oscillation of the milk liquid surface by increasing the flow resistance of the milk, so that the liquid surface of the milk in the nursing container is more stable, the overflow of the milk out of the nursing container is avoided, and the data such as the amount and the liquid level of the milk in the nursing container detected by the liquid level detection unit in the breast pump are more accurate and reliable.

[0010] Optionally, the damping device comprises a liquid resistance piece, which is arranged on the inner wall of the container body and extends from the inner wall of the container body to the milk storage space of the container body.

[0011] When the shock occurs, the liquid blocking piece can weaken the shock of the milk by reducing the flowability of the milk. In turn, the liquid level in the container body is more stable, avoiding the milk splashing out of the container body, and the data detected by the liquid level detection unit in the breast pump, such as the amount of milk in the container body and the liquid level of the milk, is more accurate and reliable.

[0012] Optionally, the number of liquid blocking pieces is at least two, and the liquid blocking pieces are dispersedly distributed on the inner wall of the container body.

[0013] When the liquid blocking piece is in contact with the milk liquid level, by arranging multiple liquid blocking pieces, the milk liquid level is further divided into more areas by the multiple liquid blocking pieces, thereby reducing the range of shock diffusion at the shock source and further weakening the shock of the milk liquid level. When the milk submerges the liquid blocking piece, the dispersedly arranged liquid blocking pieces further increase the resistance of the milk flow, thereby reducing the flowability of the milk and improving the effect of the shock attenuation device on weakening the shock of the milk.

[0014] Optionally, the liquid blocking pieces are arranged in at least two layers at different heights along the inner wall of the container body.

[0015] By arranging multiple layers of liquid blocking pieces, the liquid blocking pieces at different heights meet the milk liquid level at different liquid levels, thereby realizing the shock attenuation function of the liquid blocking pieces at different liquid levels. The submerged liquid blocking pieces exert resistance to the flow of the milk at different liquid levels, thereby improving the effect of reducing the flowability of the milk and further weakening the shock of the milk, making the liquid level of the milk in the container body more stable, avoiding the milk splashing out of the container body, and making the data detected by the liquid level detection unit in the breast pump, such as the amount of milk in the container body and the liquid level of the milk, more accurate and reliable.

[0016] Optionally, the liquid blocking pieces of adjacent layers are arranged in a staggered manner in the horizontal direction.

[0017] By arranging the liquid blocking pieces of adjacent layers in a staggered manner in the horizontal direction, the liquid blocking pieces of different layers exert resistance to the milk at different liquid levels, thereby reducing the flowability of the milk and further weakening the shock of the milk, making the liquid level of the milk in the container body more stable, avoiding the milk splashing out of the container body, and making the data detected by the liquid level detection unit in the breast pump, such as the amount of milk in the container body and the liquid level of the milk, more accurate and reliable.

[0018] Optionally, the shape of the liquid blocking piece is plate-shaped or columnar.

[0019] The shape of the liquid blocking piece is set to be plate-shaped, thereby increasing the contact area between the liquid blocking piece and the milk and improving the effect of the liquid blocking piece on weakening the shock of the milk.

[0020] By setting the shape of the liquid blocking piece as a column, the contact area of the liquid blocking piece with the milk in the vertical direction and the horizontal direction is large, thereby increasing the resistance of the liquid blocking piece to the milk in the vertical direction and the horizontal direction, and hindering the propagation of milk shock, thereby improving the effect of the liquid blocking piece on weakening milk shock.

[0021] Optionally, the liquid blocking piece is not parallel to the horizontal plane.

[0022] By making the liquid blocking piece not parallel to the horizontal plane, the liquid blocking piece can pass through the milk liquid surface for a longer time during the rising of the milk liquid surface, thereby delaying the time when the liquid blocking piece is completely submerged, prolonging the time when the liquid blocking piece hinders the shape of the milk liquid surface, and hindering the milk liquid surface for a longer time, thereby improving the effect of the liquid blocking piece on weakening milk shock.

[0023] Optionally, the cross section of the liquid blocking piece is arc-shaped, and the top of the liquid blocking piece is away from the bottom of the container body.

[0024] By setting the cross section of the liquid blocking piece as arc-shaped and making the top of the liquid blocking piece away from the bottom of the container body, the liquid blocking piece forms a structure with high middle and low sides. When the milk liquid surface rises close to the liquid blocking piece, if the milk enters the previous layer of liquid blocking piece due to vibration, it will quickly slide down along the slope, reducing the residence time of the milk in the liquid blocking piece, making the splashed milk quickly return to the whole milk, and making the data such as the amount and the liquid level of the milk in the container body detected by the liquid level detection unit of the breast pump more accurate and reliable.

[0025] Optionally, the shock absorbing device comprises a floating block, and the floating block is at least partially floating on the milk liquid surface.

[0026] During the milk pumping process of the breast pump, the height of the floating block in the container body rises with the rising of the milk liquid surface in the container body, thereby making the floating block always float on the milk liquid surface. Since the milk liquid surface has a certain tension, when shock occurs, the floating block will pull the milk through the tension of the milk liquid surface, thereby avoiding excessive amplitude of milk shock. Since the floating block always floats on the milk liquid surface, the floating block can always pull the milk through the tension of the milk liquid surface during the milk pumping process, thereby keeping the shock absorbing device in a state of absorbing shock, improving the effect of the shock absorbing device on weakening milk shock, and making the data such as the amount and the liquid level of the milk in the container body detected by the liquid level detection unit of the breast pump more accurate and reliable.

[0027] Optionally, the number of the floating blocks is at least one.

[0028] The multiple floating blocks play a damping effect at different positions of the milk liquid surface, and the multiple floating blocks hinder the propagation of the milk liquid surface shock wave, further improving the effect of the damping device in weakening the milk shock.

[0029] Optionally, the damping device further comprises a guiding assembly for limiting the movement of the floating block following the change of the milk liquid surface.

[0030] The guiding assembly limits the movement of the floating block following the change of the milk liquid surface, so that the movement direction of the floating block is only rising or falling following the change of the milk liquid surface, and the floating block will not float on the milk liquid surface due to the fluctuation of the milk liquid surface. Since the floating block only rises or falls following the change of the milk liquid surface, the floating block can be pulled by the tension of the milk liquid surface, and the propagation of the shock wave generated by the milk shock along the milk liquid surface is hindered, thereby improving the effect of the damping device in weakening the milk shock, and the data such as the amount and liquid level of the milk in the container body detected by the liquid level detection unit in the breast pump is more accurate and reliable.

[0031] Optionally, the guiding assembly comprises a sliding rail arranged on the inner wall of the container body, and the floating block is provided with a sliding block matched with the sliding rail, and the sliding block moves along the sliding rail to drive the floating block to move along the sliding rail.

[0032] The sliding rail is arranged on the inner wall of the container body, the floating block is guided by the sliding rail and the sliding block, and the movement direction of the floating block is only rising or falling following the change of the milk liquid surface, and the floating block will not float on the milk liquid surface due to the fluctuation of the milk liquid surface, thereby improving the effect of the damping device in weakening the milk shock, and the data such as the amount and liquid level of the milk in the container body detected by the liquid level detection unit in the breast pump is more accurate and reliable.

[0033] Optionally, the guiding assembly comprises a guiding line for limiting the floating block during the movement of the floating block along the milk liquid surface.

[0034] The guiding line pulls the floating block, thereby increasing the resistance of the floating block moving along the milk liquid surface, limiting the movement range of the floating block, and thereby pulling the milk by the tension of the milk liquid surface, and hindering the propagation of the shock wave generated by the milk shock along the milk liquid surface, thereby improving the effect of the damping device in weakening the milk shock, and the data such as the amount and liquid level of the milk in the container body detected by the liquid level detection unit in the breast pump is more accurate and reliable.

[0035] Optionally, one end of the guiding line is connected with the floating block, and the other end of the guiding line is connected with the bottom of the container body.

[0036] By connecting one end of the guide line to the bottom of the container body, and then making the guide line pull the floating block below the milk liquid surface, and then making the guide line anchor the floating block, limiting the moving range of the floating block along the milk liquid surface, and absorbing part of the energy of the shock wave, the effect of weakening the milk shock is achieved.

[0037] Optionally, the length of the guide line is greater than or equal to the highest liquid level height of the container body.

[0038] By making the length of the guide line greater than or equal to the height of the highest liquid level of the container body, the guide line avoids limiting the rising height of the floating block, so that the height of the floating block can always change with the change of the height of the milk liquid surface, ensuring the effect of the floating block weakening the milk shock.

[0039] Optionally, the guide line can be elastically deformed, and the length of the guide line after elastic deformation is equal to the distance from the milk liquid surface to the bottom of the container body, so that the floating block moves with the milk liquid surface under the guidance of the guide line.

[0040] By elastically deforming the guide line to pull the floating block, the floating block is subjected to the buoyancy of the milk and the elastic force of the guide line. When the floating block floats on the milk liquid surface, the floating block pulls the guide line, and then the guide line is elastically deformed, and the guide line pulls the floating block below the milk liquid surface, and then the elastic force generated by the elastic deformation limits the moving range of the floating block along the milk liquid surface, and reduces the fluctuation range of the floating block. In this way, on the one hand, the floating block pulls the milk through the tension of the milk liquid surface, and on the other hand, the floating block hinders the propagation of the shock wave along the milk liquid surface. The elastically deformed guide line can absorb more energy of the shock wave due to its own elastic force. In this way, the effect of the shock-absorbing device weakening the milk shock is improved, and the data such as the amount and liquid level of the milk in the container body detected by the liquid level detection unit in the breast pump is more accurate and reliable.

[0041] Optionally, one end of the guide line is connected to the top of the container body, the other end of the guide line is connected to the bottom of the container body, the floating block is connected in series to the guide line, and the floating block can slide along the guide line.

[0042] During the movement of the floating block with the change of the height of the milk liquid surface, the guide line guides the floating block, and then limits the movement of the floating block along the milk liquid surface, and then the floating block pulls the milk through the tension of the milk liquid surface, and hinders the propagation of the shock wave along the milk liquid surface, and then improves the effect of the shock-absorbing device weakening the milk shock, and makes the data such as the amount and liquid level of the milk in the container body detected by the liquid level detection unit in the breast pump more accurate and reliable.

[0043] Optionally, the guiding assembly comprises a first magnetic attraction element arranged along the moving direction of the milk liquid surface.

[0044] The floating block is provided with a second magnetic attraction element, and the first magnetic attraction element and the second magnetic attraction element can be attracted to each other.

[0045] During the movement of the floating block along with the change of the milk liquid surface, the second magnetic attraction element moves relative to the first magnetic attraction element.

[0046] Through the mutual attraction between the first magnetic attraction element and the second magnetic attraction element, the floating block moves along the arrangement direction of the first magnetic attraction element along with the change of the milk liquid surface, and the guiding assembly limits the movement of the floating block along the milk liquid surface, further improving the effect of the shock-absorbing device on weakening the milk shock, so that the amount and the liquid level of the milk in the container body detected by the liquid level detection unit in the breast pump are more accurate and reliable.

[0047] Optionally, the guiding assembly comprises a spring element.

[0048] One end of the spring element is connected to the floating block, and the other end of the spring element is connected to the bottom of the container body.

[0049] The length of the spring element after elastic deformation is equal to the distance from the milk liquid surface to the bottom of the container body, so that the floating block moves along with the change of the milk liquid surface under the guidance of the spring element.

[0050] The floating block is pulled by the spring element that can elastically deform, so that the floating block is subjected to the buoyant force of the milk and the elastic force of the spring element. When the floating block floats on the milk liquid surface, the floating block pulls the spring element, and the spring element elastically deforms. The spring element pulls the floating block from below the milk liquid surface, and the elastic force generated by the elastic deformation limits the movement range of the floating block along the milk liquid surface and reduces the fluctuation range of the floating block. In this way, on the one hand, the floating block pulls the milk through the tension of the milk liquid surface, and on the other hand, the shock wave generated by the milk shock is hindered from propagating along the milk liquid surface. The spring element that elastically deforms can absorb more energy of the shock wave due to its own elastic force. In this way, the effect of the shock-absorbing device on weakening the milk shock is improved, so that the amount and the liquid level of the milk in the container body detected by the liquid level detection unit in the breast pump are more accurate and reliable.

[0051] Optionally, the shock-absorbing device comprises at least one partition element, and the partition element divides the container body into at least two chambers, and the chambers are in communication with each other.

[0052] The container body is divided into multiple chambers by the partitions, thereby reducing the energy transfer between the milk in the chambers of the container body, and weakening the shock of the milk in the chambers of the container body. The chambers are in communication with each other, so that the milk in the container body has a unified height of the milk surface, thereby ensuring the accuracy and reliability of the data detected by the liquid level detection unit, such as the amount of milk and the liquid level of the milk in the container body.

[0053] Optionally, the chambers are arranged in sequence in the transverse direction, and the adjacent chambers are in communication at the top and bottom of the container body.

[0054] By arranging the chambers in the longitudinal direction and arranging the chambers in sequence in the transverse direction, the milk surface is divided into multiple regions by the partitions, and the transmission of the shock wave between the regions of the milk surface is blocked by the partitions, thereby improving the effect of the shock absorption device on weakening the shock of the milk. By communicating the chambers from the bottom of the container body, the consistency of the height of the milk level between the chambers is ensured. By communicating the chambers at the top of the container body, the air pressure between the chambers is balanced, so that the milk can be uniformly distributed in the chambers, and the consistency of the height of the milk level between the chambers is further ensured, so that the data detected by the liquid level detection unit in the breast pump, such as the amount of milk and the liquid level of the milk in the container body, is more accurate and reliable.

[0055] Optionally, the chambers are arranged in sequence in the longitudinal direction, and the communication ports between the chambers are arranged on the side of the chambers, and the adjacent communication ports are arranged on the two sides of the chambers, so that the milk flows in the transverse direction.

[0056] When the milk enters the container body, it passes through the chambers in sequence from the higher layer of chambers through the communication ports to the chamber in the layer of the milk surface, so that the milk surface is raised. When the shock occurs, the resistance of the milk flow is increased by the partitions below the milk surface, the shock of the milk surface is limited by the partitions in contact with the milk surface, and the peak height of the shock wave in the milk surface is limited by the partitions above the milk surface, thereby improving the effect of the shock absorption device on weakening the shock of the milk, and making the data detected by the liquid level detection unit in the breast pump, such as the amount of milk and the liquid level of the milk in the container body, more accurate and reliable.

[0057] In a second aspect, the application also provides a breast pump, comprising:

[0058] A milk storage container for receiving and storing milk;

[0059] A shield assembly for fitting with the breast of a user and accommodating at least the nipple of the user, receiving milk and introducing the milk into the milk storage container;

[0060] a negative pressure mechanism for directly or indirectly applying negative pressure to the shield assembly;

[0061] a main housing, the negative pressure mechanism is at least partially arranged in the main housing, the breast pump is assembled, and the main housing is at least partially in contact with the outer wall of the milk storage container;

[0062] a detection mechanism, the detection mechanism comprises a capacitive detection sensor, the capacitive detection sensor is arranged on the main housing, and the capacitive detection sensor can detect the amount of milk in the milk storage container or milk fullness when the breast pump is working.

[0063] The height of the milk liquid level in the milk storage container can be effectively detected by the capacitive detection sensor, and the amount of milk loaded in the milk storage container and the milk fullness of the milk storage container can be detected. By arranging the damping device in the milk storage container, the oscillation of the milk liquid level in the milk storage container is weakened, thereby reducing the phenomenon of milk wall hanging on the inner wall of the milk storage container, thereby reducing the influence of milk liquid level oscillation or milk wall hanging on the detection result of the detection mechanism, and making the detection result of the detection mechanism more accurate and reliable.

[0064] Optionally, the detection mechanism further comprises:

[0065] a detection module, the detection module is electrically connected or communicatively connected to the capacitive detection sensor, and can feed back the amount of milk or milk fullness information according to the data detected by the capacitive detection sensor.

[0066] The amount of milk or milk fullness information is fed back through the detection module, so that the control module of the breast pump can control the breast pump according to the amount of milk or milk fullness information, and send a prompt or an alarm according to the amount of milk or milk fullness information, so that the user can more timely understand the breast pumping situation and make corresponding response during the breast pumping process. The obtained amount of milk information or milk fullness information can also be fed back to the mobile terminal or computer terminal of the user through remote communication, so that the user can real-time understand the parameter information of the breast pump, or adjust the breast pumping plan according to the historical parameter information of the breast pump

[0067] Optionally, the milk storage container comprises a milk pouring opening near the top, the damping device comprises a damping member fixed near the lower part of the milk pouring opening, and the capacitive detection sensor at least comprises a detection unit arranged between the damping member and the milk pouring opening.

[0069] Optionally, the damping device comprises a plurality of damping members arranged in layers from the bottom of the milk storage container to the top of the milk storage container, and the detection unit is located between the milk outlet and the uppermost damping member.

[0070] The damping members of different layers can dampen the milk surface of different liquid levels, thereby improving the damping effect of the damping device. By arranging the damping members between the milk outlet and the uppermost damping member, when the milk is close to the detection unit, the damping members can increase the flow resistance of the milk, weaken the oscillation of the milk surface, and make the liquid level of the milk in the milk storage container more stable, thereby reducing the influence of the fluctuation of the milk surface on the detection result of the detection unit, and enabling the detection unit to more accurately detect whether the milk storage container reaches the full state.

[0071] The above technical scheme has the beneficial effects that: the damping device is installed in the container body of the milk storage container, when the milk in the container body shakes, the damping device increases the flow resistance of the milk, weakens the oscillation of the milk surface, and makes the liquid level of the milk in the milk storage container more stable, thereby reducing the adhesion amount of the milk on the inner wall of the milk storage container, avoiding the overflow of the milk from the milk storage container, and making the data such as the amount and the liquid level of the milk in the milk storage container detected by the liquid level detection unit in the breast pump more accurate and reliable, and improving the use convenience of the breast pump.

[0120] In the above-mentioned embodiment of the breast pump sealing structure, the elastic sealing part is integrally formed with the second assembly part; and in other embodiments, the purpose of integrally forming the elastic sealing structure with the above-mentioned three second assembly parts is to simplify the processing and installation process of the breast pump during production, and improve the processing efficiency of the breast pump.

[0121] In the above-mentioned embodiment of the breast pump sealing structure, the elastic sealing part is detachably installed on the second assembly part and matched with the first assembly part; the purpose is to make it possible to meet the user's operation of taking out the breast pump sealing structure for cleaning, replacement, maintenance and the like, and improve the convenience when designing some breast pump products that need to take out the breast pump sealing structure.

[0122] In the above-mentioned embodiment of the breast pump sealing structure, the guide sealing part comprises a first side and a second side, the first side forms a first included angle with the second assembly part, and the second side forms a second included angle with the second assembly part.

[0123] The first included angle is directed to the moving direction of the first fitting part during assembly, and the second included angle is directed to the moving direction of the first fitting part during disassembly;

[0124] The first included angle is obtuse.

[0125] The first side abuts against the side wall of the second fitting part to generate deformation, so that the angle of the first included angle increases, and the second side is deformed along with the deformation of the first side, so that the angle of the second included angle decreases. When the elastic sealing part is assembled with the second fitting part, the angles of the first included angle and the second included angle stop changing, at which time the assembly gap between the first fitting part and the second fitting part is sealed, the first included angle is obtuse, and the second included angle is a right angle.

[0126] In the above-mentioned embodiment of the breast pump sealing structure, the angle of the second included angle is less than and / or equal to the angle of the first included angle. The purpose of setting this structure is to make the structure of the guide sealing part more suitable for the structure between the installed first fitting part and / or second fitting part, so that different structure guide sealing part breast pump products can be designed to meet different user needs and use scenarios.

[0127] In the above-mentioned embodiment of the breast pump sealing structure, the cross section of the guide sealing part is triangular, and the angle of the second included angle is less than or equal to 90 degrees. The different inclination structures of the first included angle and the second included angle of the guide sealing part increase the extrusion force after the assembly of the first fitting part and the second fitting part, increase the deformation amount, and effectively avoid the falling of the first fitting part.

[0128] In the above-mentioned embodiment of the breast pump sealing structure, when the first fitting part is assembled with the second fitting part, the guide sealing part is inclined to the moving direction of the first fitting part during assembly. The first side forms an extension surface, and the second side forms a compression surface, so that the guide sealing part forms an elastic force for extruding the first fitting part, thereby facilitating the sealing effect of the elastic sealing part, and at the same time, the required force for disassembling the first fitting part is greater, which is more conducive to avoiding the falling of the first fitting part.

[0129] In the above-mentioned embodiment of the breast pump sealing structure, the cross section of the first side and / or second side is arc-shaped or a straight line segment. The different inclination structures of the first included angle and the second included angle of the guide sealing part make the cross section of the first side and / or second side arc-shaped or a straight line segment, further increase the extrusion force after the assembly of the first fitting part and the second fitting part, increase the deformation amount, and effectively avoid the falling of the first fitting part.

[0130] In the embodiment of the sealing structure of the breast pump, the first side and the second side are connected and form an acute angle therebetween, or the first side and the second side are connected through a third side, and the first side and the second side are connected through the third side, so that the whole guiding sealing part is more closely attached to the inner side wall of the second assembly.

[0247] Embodiment One

[0248] Referring to FIGS. 1-7, in some embodiments of the present application, a breast pump 1 is provided, which includes a milk storage container 10, a main machine 20, a shield assembly 30, a negative pressure mechanism 22, and a detection mechanism 90.

[0249] The milk storage container 10 is used to load milk. The shield assembly 30 is used to fit with the user's breast and at least accommodate the user's nipple. The negative pressure mechanism 22 is used to directly or indirectly apply negative pressure to the shield assembly 30. The detection mechanism 90 is used to detect the amount of milk or the milk level L or the milk fullness or the milk overflow in the milk storage container 10.

[0250] During the breast pumping process, the negative pressure mechanism 22 generates negative pressure in the space between the shield assembly 30 and the user's breast, thereby sucking the milk in the user's breast through negative pressure. The pumped milk flows through the milk passage in the shield assembly 30 to the milk storage container 10, and the milk storage container 10 loads the milk.

[0251] In some embodiments of the present application, the negative pressure mechanism 22 is provided in the main machine 20. The main machine 20 also includes a control circuit board and other electronic components for controlling the operation of the negative pressure mechanism 22.

[0252] In some embodiments of the present application, the detection mechanism 90 includes a weight sensor.

[0253] The weight of the milk storage container 10 after loading milk is detected by the weight sensor, thereby detecting the amount of milk in the milk storage container 10.

[0254] In some embodiments of the present application, the detection mechanism 90 includes a distance sensor, and when the milk storage container 10 is loaded with milk, the detection direction of the distance sensor is towards the milk level L.

[0255] The distance sensor detects the milk level L in the milk storage container 10, and then calculates the amount of milk in the milk storage container 10. When the milk level L in the milk storage container 10 approaches the full milk level, it is determined that the milk storage container 10 is close to the full milk state; when the milk level L in the milk storage container 10 reaches the full milk level, it is determined that the milk storage container 10 is in the full milk state; and when the milk level L in the milk storage container 10 exceeds the full milk level, it is determined that the milk storage container 10 is in the milk overflow state.

[0256] Referring to FIG. 2, in some embodiments of the present application, the detection mechanism 90 includes a capacitive sensor.

[0257] During the breast pumping process, the milk level L in the milk storage container 10 changes, and the capacitance value of the capacitive sensor also changes, thereby detecting the milk level L in the milk storage container 10.

[0258] Referring to FIGS. 1-5, in some embodiments of the present application, a breast pump 1 is provided, which includes a milk storage container 10, a shield assembly 30, a negative pressure mechanism 22, a main housing 21, and a detection mechanism 90. The milk storage container 10 is used to receive and store milk. The shield assembly 30 is used to fit with the user's breast and at least accommodate the user's nipple, receive milk, and introduce the milk into the milk storage container 10. The negative pressure mechanism 22 is used to directly or indirectly apply negative pressure to the shield assembly 30. The negative pressure mechanism 22 is at least partially disposed in the main housing 21, and the main housing 21 at least partially contacts the outer wall of the milk storage container 10 when the breast pump 1 is assembled. The detection mechanism 90 includes a capacitive detection sensor 91 disposed on the main housing 21, which can detect the amount of milk or the full milk state in the milk storage container 10 when the breast pump 1 is working.

[0259] Referring to FIGS. 3-4, in some embodiments of the present application, the detection mechanism 90 is located on one side of the main housing 21 close to the milk storage container 10. The detection mechanism 90 can be disposed on the inner wall of the main housing 21, or on the outer wall of the main housing 21, or embedded in the main housing 21. The detection mechanism 90 can contact the side wall of the milk storage container 10, or have a certain gap with the milk storage container 10.

[0260] The capacitive detection sensor 91 can effectively detect the height of the milk level L in the milk storage container 10, and then detect the amount of milk loaded in the milk storage container 10 and the full milk state of the milk storage container 10. By providing the damping device 12 in the milk storage container 10, the oscillation of the milk level L in the milk storage container 10 is weakened, thereby reducing the phenomenon of milk hanging on the inner wall of the milk storage container 10, and reducing the influence of the oscillation of the milk level L or the milk hanging on the detection result of the detection mechanism 90, so that the detection result of the detection mechanism 90 is more accurate and reliable.

[0261] Referring to FIGS. 1-4, in some embodiments of the present application, the detection mechanism 90 further comprises a detection module 93 electrically connected or communicatively connected to the capacitive detection sensor 91 and capable of feeding back milk volume or milk fullness information according to the data detected by the capacitive detection sensor 91.

[0262] By feeding back milk volume or milk fullness information through the detection module 93, the control module of the breast pump 1 can control the breast pump 1 according to the milk volume or milk fullness information and issue a prompt or an alarm according to the milk volume or milk fullness information, so that the user can more timely understand the breast pumping situation and make corresponding responses during the breast pumping process. The obtained milk volume information or milk fullness information can also be fed back to the mobile terminal or computer terminal of the user through remote communication, so that the user can real-time understand the parameter information of the breast pump 1 or adjust the breast pumping plan according to the historical parameter information of the breast pump 1.

[0263] Referring to FIG. 5, in some embodiments of the present application, the milk storage container 10 comprises a milk pouring port 112 located near the top, the shock-absorbing device 12 comprises a shock-absorbing piece 121 fixed near the lower part of the milk pouring port 112, and the capacitive detection sensor 91 at least comprises a detection unit 92 arranged between the shock-absorbing piece 121 and the milk pouring port 112.

[0264] By arranging the detection unit 92 near the milk pouring port 112 of the milk storage container 10, the detection unit 92 can be triggered when the milk approaches the milk pouring port 112, and then the milk fullness of the breast pump 1 can be monitored through the detection unit 92 to avoid milk overflow.

[0265] In some embodiments of the present application, the shock-absorbing device 12 comprises a plurality of shock-absorbing pieces 121 arranged in layers from the bottom of the milk storage container 10 to the top of the milk storage container 10, and the detection unit 92 is located between the milk pouring port 112 and the uppermost shock-absorbing piece 121.

[0266] The milk surface L of different liquid levels is shock-absorbed through the plurality of shock-absorbing pieces 121, thereby improving the shock-absorbing effect of the shock-absorbing device 12. By arranging the shock-absorbing piece 121 between the milk pouring port 112 and the uppermost shock-absorbing piece 121, the resistance of milk flow is increased through the shock-absorbing piece 121 when the milk approaches the detection unit 92, the oscillation of the milk surface L is weakened, and the milk surface in the milk storage container 10 is more stable, thereby reducing the influence of the milk surface L fluctuation on the detection result of the detection unit 92, so that the detection unit 92 can more accurately detect whether the milk storage container 10 reaches the milk fullness state.

[0267] In some embodiments of the present application, the milk storage container 10 comprises a container body 11 and a shock-absorbing device 12. The shock-absorbing device 12 is at least partially arranged in the container body 11. The shock-absorbing device 12 is used to weaken the oscillation of the milk surface L.

[0268] The damping device 12 is installed in the container body 11. When the milk in the container body 11 shakes, the damping device 12 weakens the oscillation of the milk surface L by increasing the flow resistance of the milk, and further stabilizes the milk surface in the container body 11, avoids the milk from spilling out of the container body 11, and makes the data such as the amount of milk and the milk level in the container body 11 detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0269] Please refer to FIG. 1 to FIG. 7. In some embodiments of the present application, the damping device 12 includes a liquid blocking piece 122, which is arranged on the inner wall of the container body 11 and extends from the inner wall of the container body 11 to the milk storage space of the container body 11.

[0270] Please refer to FIG. 6 to FIG. 7. During the process of milk pumping by the breast pump 1, the milk surface L in the container body 11 rises with the increase of the amount of milk in the container body 11.

[0271] When the liquid blocking piece 122 contacts the milk surface L, an obstacle is formed at the milk surface L, and the milk surface L is divided into multiple areas. When the oscillation occurs, the oscillation of the milk surface L is weakened due to the obstruction of the liquid blocking piece 122. By dividing the milk surface L into multiple areas through the liquid blocking piece 122, the energy transfer between the areas of the milk surface L is reduced. When the liquid surface oscillation occurs at the source, the energy at the source is the largest, and thus the oscillation at the source is the strongest. By reducing the energy transfer between the areas of the milk surface L through the liquid blocking piece 122, the oscillation of the areas of the milk surface L that do not contain the source is weakened. The milk surface in the container body 11 is further stabilized, the milk is prevented from splashing out of the container body 11, and the data such as the amount of milk and the milk level in the container body 11 detected by the liquid level detection unit in the breast pump 1 are more accurate and reliable.

[0272] Since the milk surface L has tension, when the oscillation occurs, the inner wall of the container body 11 and the liquid blocking piece 122 will pull the milk through the tension of the milk surface L, and thus the oscillation of the milk is avoided. By arranging the liquid blocking piece 122, the range of the milk surface L being pulled is increased, and thus the oscillation of the milk surface L is weakened.

[0273] When the height of the milk surface L exceeds the liquid blocking piece 122, that is, when the milk submerges the liquid blocking piece 122, the flow of the milk is blocked by the liquid blocking piece 122, the resistance of the milk flow is increased, and thus the flowability of the milk is reduced. When the oscillation occurs, the liquid blocking piece 122 can weaken the oscillation of the milk by reducing the flowability of the milk. The milk surface in the container body 11 is further stabilized, the milk is prevented from splashing out of the container body 11, and the data such as the amount of milk and the milk level in the container body 11 detected by the liquid level detection unit in the breast pump 1 are more accurate and reliable.

[0274] In some embodiments of the present application, the liquid blocking member 122 can be flexible. The liquid blocking member 122 can be integrally formed with the container body 11, or can be combined with the container body 11 by secondary forming after the container body 11 is formed, or can be combined with the container body 11 by bonding or welding, or can be combined with the container body 11 by other methods that do not introduce contaminants.

[0275] By setting the liquid blocking member 122 to be flexible, the liquid blocking member 122 can deform when the container body 11 is cleaned, thereby facilitating cleaning of the interior space of the container body 11, while reducing the shock of the milk in the container body 11 by the liquid blocking member 122.

[0276] In some embodiments of the present application, the material of the liquid blocking member 122 can be flexible rubber, preferably flexible silicone rubber.

[0277] In some embodiments of the present application, the number of liquid blocking members 122 is at least two, and the liquid blocking members 122 are dispersedly distributed on the inner wall of the container body 11.

[0278] When the liquid blocking member 122 is in contact with the milk liquid level L, by providing a plurality of liquid blocking members 122, the milk liquid level L is further divided into more areas by the plurality of liquid blocking members 122, thereby reducing the range of shock diffusion at the shock source and further reducing the shock of the milk liquid level L.

[0279] When the milk submerges the liquid blocking member 122, the flow of the milk is blocked by the dispersedly arranged liquid blocking members 122, further increasing the resistance when the milk flows, thereby reducing the flowability of the milk, and thereby improving the effect of the shock reduction device 12 on reducing the shock of the milk. The liquid level of the milk in the container body 11 is more stable, the milk is prevented from splashing out of the container body 11, and the data such as the amount and liquid level of the milk in the container body 11 detected by the liquid level detection unit in the breast pump 1 is more accurate and reliable.

[0280] In some embodiments of the present application, the liquid blocking member 122 is arranged in at least two layers at different heights along the inner wall of the container body 11.

[0281] By providing multiple layers of liquid blocking members 122, the liquid blocking members 122 at different heights meet the milk liquid level L at different liquid levels, thereby achieving the shock reduction function of the liquid blocking members 122 at different liquid levels.

[0282] The liquid blocking piece 122 submerged in the milk exerts resistance to the flow of the milk at different liquid levels, thereby improving the effect of reducing the flowability of the milk, further weakening the shock of the milk, making the liquid surface of the milk in the container body 11 more stable, avoiding the splashing of the milk out of the container body 11, and making the data such as the amount and liquid level of the milk in the container body 11 detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0283] In some embodiments of the present application, the liquid blocking pieces 122 of adjacent layers are arranged staggered in the horizontal direction.

[0284] The liquid blocking pieces 122 of adjacent layers are arranged staggered in the horizontal direction, which can be understood as that the projections of the liquid blocking pieces 122 of adjacent layers on the bottom of the container body 11 do not coincide, and in some cases, the projections of the liquid blocking pieces 122 of adjacent layers on the bottom of the container body 11 can also partially overlap.

[0285] By arranging the liquid blocking pieces 122 of adjacent layers staggered in the horizontal direction, the liquid blocking pieces 122 of different layers exert resistance to the milk at different liquid levels, thereby reducing the smoothness of the flow of the milk, further weakening the shock of the milk, making the liquid surface of the milk in the container body 11 more stable, avoiding the splashing of the milk out of the container body 11, and making the data such as the amount and liquid level of the milk in the container body 11 detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0286] It can be understood that if the projections of the liquid blocking pieces 122 of adjacent layers on the bottom of the container body 11 coincide, a milk channel from the bottom of the container body 11 to the top of the container body 11 will be formed between the liquid blocking pieces 122, and when the milk flows over the liquid blocking pieces 122 of the lower layer to the top of the container body 11, the liquid blocking pieces 122 of the higher layer cannot block the milk, thereby reducing the effect of weakening the shock of the milk by the liquid blocking pieces 122.

[0287] By arranging the liquid blocking pieces 122 of adjacent layers staggered in the horizontal direction, when the milk flows over the liquid blocking pieces 122 of the lower layer to the top of the container body 11, the liquid blocking pieces 122 of the higher layer will block the milk, further increasing the resistance of the milk flow, thereby improving the effect of weakening the shock of the milk by the liquid blocking pieces 122.

[0288] In some embodiments of the present application, the shape of the liquid blocking piece 122 is plate-shaped or columnar.

[0289] The liquid blocking piece 122 is arranged on the inner wall of the container body 11, and the liquid blocking piece 122 extends from the inner wall of the container body 11 to the milk storage space of the container body 11. By increasing the resistance of the milk shaking in the container body 11 through the liquid blocking piece 122, the effect of weakening the shock of the milk in the container body 11 is achieved.

[0290] The shape of the liquid blocking piece 122 is set as a plate shape, thereby increasing the contact area of the liquid blocking piece 122 with the milk, and improving the effect of the liquid blocking piece 122 on weakening the shock of the milk.

[0291] In some embodiments of the present application, the plate-shaped liquid blocking piece 122 can be parallel to the horizontal plane or perpendicular to the horizontal plane.

[0292] When the human body moves up and down in the vertical direction, the breast pump 1 moves in the vertical direction, which causes the milk in the container body 11 to move in the vertical direction relative to the container body 11. The plate-shaped liquid blocking piece 122 is set parallel to the horizontal plane, thereby increasing the contact area of the liquid blocking piece 122 with the milk in the horizontal direction, and increasing the resistance of the liquid blocking piece 122 to the milk in the vertical direction, thereby reducing the amplitude of the relative movement of the milk in the vertical direction relative to the container body 11, i.e., weakening the shock of the milk in the container body 11.

[0293] When the human body moves in the horizontal direction, the breast pump 1 moves in the horizontal direction, which causes the milk in the container body 11 to move in the horizontal direction relative to the container body 11. The plate-shaped liquid blocking piece 122 is set perpendicular to the horizontal plane, thereby increasing the contact area of the liquid blocking piece 122 with the milk in the vertical direction, and increasing the resistance of the liquid blocking piece 122 to the milk in the horizontal direction. When the milk in the container body 11 is shocked, the shock wave propagates in the horizontal direction along the milk liquid surface L. By increasing the resistance of the milk to move in the horizontal direction through the liquid blocking piece 122, the propagation of the milk shock in the horizontal direction is hindered, thereby weakening the shock of the entire milk liquid surface L.

[0294] In some embodiments of the present application, the shape of the liquid blocking piece 122 is set as a column shape.

[0295] By setting the shape of the liquid blocking piece 122 as a column shape, the contact area of the liquid blocking piece 122 with the milk in the vertical direction and the horizontal direction is large, thereby increasing the resistance of the liquid blocking piece 122 to the milk in the vertical direction and the horizontal direction, and hindering the propagation of the milk shock, thereby improving the effect of the liquid blocking piece 122 on weakening the shock of the milk.

[0296] In some embodiments of the present application, the cross-sectional shape of the column-shaped liquid blocking piece 122 can include a circular shape, a square shape, a rectangular shape, a polygonal shape, an elliptical shape, or other shapes that can form a columnar body. The liquid blocking piece 122 is arranged on the inner wall of the container body 11 and extends from the inner wall of the container body 11 to the milk storage space of the container body 11.

[0297] In some embodiments of the present application, the liquid blocking piece 122 is not parallel to the horizontal plane.

[0298] The liquid blocking piece 122 is not parallel to the horizontal plane, and when the milk liquid level L rises to the height of the liquid blocking piece 122, the liquid blocking piece 122 can pass through the milk liquid level L for a longer time during the rising of the milk liquid level L, thereby delaying the time when the liquid blocking piece 122 is completely submerged, prolonging the time when the liquid blocking piece 122 obstructs the shape of the milk liquid level L, and thus improving the effect of the liquid blocking piece 122 on weakening the milk shock.

[0299] Please refer to FIG. 7. In some embodiments of the present application, the cross section of the liquid blocking piece 122 is arc-shaped, and the top of the liquid blocking piece 122 is away from the bottom of the container body 11.

[0300] By setting the cross section of the liquid blocking piece 122 as arc-shaped and making the top of the liquid blocking piece 122 away from the bottom of the container body 11, the liquid blocking piece 122 forms a structure with high middle and low sides. When the milk liquid level L rises to near the liquid blocking piece 122, if the milk enters the upper layer of the liquid blocking piece 122 due to vibration, the milk will quickly slide down along the slope, reducing the time of the milk staying in the liquid blocking piece 122, and making the splashed milk quickly return to the whole milk, so that the data such as the amount of milk and the liquid level of milk in the container body 11 detected by the liquid level detection unit in the breast pump 1 are more accurate and reliable.

[0301] Embodiment Two

[0302] Please refer to FIG. 8. In some embodiments of the present application, the shock absorbing device 12 comprises a floating block 123, and the floating block 123 at least partially floats on the milk liquid level L.

[0303] The container body 11 is provided with the floating block 123, and during the milk pumping process of the breast pump 1, the height of the floating block 123 in the container body 11 rises with the rising of the milk liquid level L in the container body 11, thereby making the floating block 123 always float on the milk liquid level L. Since the milk liquid level L has a certain tension, when the shock occurs, the floating block 123 will pull the milk through the tension of the milk liquid level L, thereby avoiding the milk shock amplitude being too large. Since the floating block 123 always floats on the milk liquid level L, the floating block 123 can always pull the milk through the tension of the milk liquid level L during the milk pumping process, thereby making the shock absorbing device 12 keep the state of absorbing the milk shock, improving the effect of the shock absorbing device 12 on weakening the milk shock, and making the data such as the amount of milk and the liquid level of milk in the container body 11 detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0304] In some embodiments of the present application, the number of the floating blocks 123 is at least one.

[0305] The multiple floating blocks 123 play a damping role at different positions of the milk liquid surface L, and the multiple floating blocks 123 hinder the propagation of the milk liquid surface L oscillation wave, further improving the effect of the damping device 12 on weakening the milk oscillation.

[0306] In some embodiments of the present application, the damping device 12 further comprises a guide assembly 124 for limiting the movement of the floating block 123 following the change of the milk liquid surface L.

[0307] The guide assembly 124 limits the movement of the floating block 123 following the change of the milk liquid surface L, so that the movement direction of the floating block 123 is only rising or falling with the change of the milk liquid surface L, and the floating block 123 will not float on the milk liquid surface L due to the fluctuation of the milk liquid surface L. Since the floating block 123 only rises or falls with the change of the milk liquid surface L, the floating block 123 can be pulled by the tension of the milk liquid surface L, and the propagation of the oscillation wave generated by the milk oscillation along the milk liquid surface L is hindered, thereby improving the effect of the damping device 12 on weakening the milk oscillation, and making the data such as the amount of milk in the container body 11 and the liquid level of the milk detected by the liquid level detection unit of the breast pump 1 more accurate and reliable.

[0308] Please refer to FIGS. 9-10, in some embodiments of the present application, the guide assembly 124 comprises a sliding rail 1241 arranged on the inner wall of the container body 11, and the floating block 123 is provided with a sliding block 1242 adapted to the sliding rail 1241, and the sliding block 1242 moves along the sliding rail 1241 to drive the floating block 123 to move along the sliding rail 1241.

[0309] The sliding rail 1241 is installed on the inner wall of the container body 11, and the floating block 123 is guided by the sliding rail 1241 through the guide structure of the sliding rail sliding block, so that the movement direction of the floating block 123 is only rising or falling with the change of the milk liquid surface L, and the floating block 123 will not float on the milk liquid surface L due to the fluctuation of the milk liquid surface L, thereby improving the effect of the damping device 12 on weakening the milk oscillation, and making the data such as the amount of milk in the container body 11 and the liquid level of the milk detected by the liquid level detection unit of the breast pump 1 more accurate and reliable.

[0310] In some embodiments of the present application, the guide direction of the sliding rail 1241 is along the direction from the bottom to the top of the container body 11.

[0311] The floating block 123 is guided by the sliding rail 1241, so that the floating block 123 further rises or falls in the direction from the bottom to the top of the container body 11, thereby limiting the movement of the floating block 123 following the change of the milk liquid surface L.

[0312] Please refer to FIG. 9, in some embodiments of the present application, the sliding rail 1241 is provided with a guide groove 1243, the sliding block 1242 is provided with an adaptive protrusion 1244, the adaptive protrusion 1244 is inserted into the guide groove 1243, and the adaptive protrusion 1244 can slide in the guide groove 1243 along the guide direction of the guide groove 1243. The guide direction of the guide groove 1243 is arranged along the moving direction of the milk liquid surface L.

[0313] The sliding rail 1241 guides the sliding block 1242 through the cooperation of the guide groove 1243 and the adaptive protrusion 1244, thereby limiting the movement of the floating block 123, and thereby making the moving direction of the floating block 123 be only rising or falling with the change of the milk liquid surface L, and not floating and moving on the milk liquid surface L due to the fluctuation of the milk liquid surface L.

[0314] Please refer to FIG. 10, in some embodiments of the present application, the guide assembly 124 is provided with a guide protrusion 1245, the floating block 123 is provided with an adaptive groove 1246, the guide protrusion 1245 is inserted into the adaptive groove 1246, and the floating block 123 can move along the guide direction of the guide protrusion 1245 relative to the guide protrusion 1245 under the cooperation of the guide protrusion 1245 and the adaptive groove 1246. The guide direction of the guide protrusion 1245 is arranged along the moving direction of the milk liquid surface L.

[0315] The sliding rail 1241 cooperates between the guide protrusion 1245 and the adaptive groove 1246, thereby limiting the movement of the floating block 123, and thereby making the moving direction of the floating block 123 be only rising or falling with the change of the milk liquid surface L, and not floating and moving on the milk liquid surface L due to the fluctuation of the milk liquid surface L.

[0316] Please refer to FIGS. 11 to 13, in some embodiments of the present application, the guide assembly 124 includes a guide line 1247 for limiting the floating block 123 during the movement of the floating block 123 along with the milk liquid surface L.

[0317] During the movement of the floating block 123 along with the change of the milk liquid surface L, the floating block 123 is pulled by the guide line 1247, thereby increasing the resistance of the floating block 123 moving along the milk liquid surface L, thereby limiting the movement range of the floating block 123, thereby making the floating block 123 pull the milk through the tension of the milk liquid surface L, and hindering the propagation of the shock wave generated by the milk shock along the milk liquid surface L, thereby improving the effect of the shock-absorbing device 12 weakening the milk shock, and making the data such as the amount and the liquid level of the milk in the container main body 11 detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0318] When the oscillation wave propagating along the milk liquid surface L is transmitted to the floating block 123, the floating block 123 will vibrate. Since the floating block 123 is a whole structure, the amplitude generated is small, so that part of the energy of the oscillation wave can be absorbed by the floating block 123, achieving the effect of weakening the milk oscillation. The guide wire 1247 is connected to the floating block 123, so that the vibration generated by the oscillation wave is transmitted to the guide wire 1247 through the floating block 123, causing the guide wire 1247 to vibrate, and then absorbing part of the energy of the oscillation wave through the guide wire 1247, further improving the effect of weakening the milk oscillation.

[0319] Please refer to FIGS. 11-12. In some embodiments of the present application, one end of the guide wire 1247 is connected to the floating block 123, and the other end of the guide wire 1247 is connected to the bottom of the container body 11.

[0320] By connecting one end of the guide wire 1247 to the bottom of the container body 11, the guide wire 1247 then pulls the floating block 123 from below the milk liquid surface L, and the guide wire 1247 then plays an anchoring role on the floating block 123, limiting the movement range of the floating block 123 along the milk liquid surface L, and absorbing part of the energy of the oscillation wave, achieving the effect of weakening the milk oscillation.

[0321] Please refer to FIG. 11. In some embodiments of the present application, the length of the guide wire 1247 is greater than or equal to the highest liquid level height of the container body 11.

[0322] By making the length of the guide wire 1247 greater than or equal to the height of the highest liquid level of the container body 11, the guide wire 1247 is then prevented from limiting the rising height of the floating block 123, so that the height of the floating block 123 can always change with the change in the height of the milk liquid surface L, ensuring the effect of the floating block 123 weakening the milk oscillation.

[0323] Please refer to FIG. 12. In some embodiments of the present application, the guide wire 1247 can elastically deform, and the length of the guide wire 1247 after elastic deformation is equal to the distance from the milk liquid surface L to the bottom of the container body 11, so that the floating block 123 moves with the milk liquid surface L under the guidance of the guide wire 1247.

[0324] The floating block 123 is pulled by the guiding line 1247 which can elastically deform, so that the floating block 123 is subjected to the milk floating force and the elastic force of the guiding line 1247. When the floating block 123 floats on the milk liquid surface L, the floating block 123 pulls the guiding line 1247, and the guiding line 1247 elastically deforms to pull the floating block 123 below the milk liquid surface L, and the elastic force generated by the elastic deformation limits the moving range of the floating block 123 along the milk liquid surface L, and reduces the fluctuation range of the floating block 123, so as to pull the milk through the tension of the floating block 123 on the milk liquid surface L, and hinder the propagation of the shock wave generated by the milk shock along the milk liquid surface L. The guiding line 1247 which elastically deforms can absorb more energy of the shock wave due to its own elastic force. In this way, the effect of the shock absorption device 12 on weakening the milk shock is improved, and the data such as the amount and the liquid level of the milk in the container main body 11 detected by the liquid level detection unit in the breast pump 1 is more accurate and reliable.

[0325] Please refer to FIG. 13, in some embodiments of the present application, one end of the guiding line 1247 is connected to the top of the container main body 11, the other end of the guiding line 1247 is connected to the bottom of the container main body 11, and the floating block 123 is connected in series to the guiding line 1247, and the floating block 123 can slide along the guiding line 1247.

[0326] In the process of moving of the floating block 123 along with the change of the height of the milk liquid surface L, the floating block 123 is guided by the guiding line 1247, so as to limit the movement of the floating block 123 along the milk liquid surface L, to pull the milk through the tension of the floating block 123 on the milk liquid surface L, and to hinder the propagation of the shock wave generated by the milk shock along the milk liquid surface L, so as to improve the effect of the shock absorption device 12 on weakening the milk shock, and make the data such as the amount and the liquid level of the milk in the container main body 11 detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0327] In some embodiments of the present application, the guiding line 1247 is in a straightened state.

[0328] The floating block 123 is guided by the guiding line 1247 which is in a straightened state, so as to improve the effect of the shock absorption device 12 on weakening the milk shock. And the guiding line 1247 which is in a straightened state can better absorb the energy of the shock wave, further improve the effect of the shock absorption device 12 on weakening the milk shock, and make the data such as the amount and the liquid level of the milk in the container main body 11 detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0329] Please refer to FIG. 14 to FIG. 15, in some embodiments of the present application, the guiding assembly 124 comprises a first magnetic member 124A arranged along the moving direction of the milk liquid surface L. The float 123 is provided with a second magnetic member 123A, the first magnetic member 124A and the second magnetic member 123A can be mutually adsorbed. During the movement of the float 123 along with the change of the milk liquid surface L, the second magnetic member 123A moves relative to the first magnetic member 124A.

[0330] Through the mutual adsorption between the first magnetic member 124A and the second magnetic member 123A, the float 123 moves along the arrangement direction of the first magnetic member 124A along with the change of the milk liquid surface L, and the guiding assembly 124 limits the movement of the float 123 along the milk liquid surface L, further improving the effect of the shock-absorbing device 12 on weakening the milk shock, and making the data such as the amount and the liquid level of the milk in the container main body 11 detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0331] In some embodiments of the present application, the first magnetic member 124A can comprise a permanent magnet, and the second magnetic member 123A can comprise at least one of a permanent magnet or a ferromagnetic material.

[0332] In some embodiments of the present application, the first magnetic member 124A can comprise at least one of a permanent magnet or a ferromagnetic material, and the second magnetic member 123A can comprise a permanent magnet.

[0333] In some embodiments of the present application, the first magnetic member 124A can be wrapped by a food-grade material (such as a silica gel sleeve, etc.) to avoid the first magnetic member 124A from polluting the milk.

[0334] In some embodiments of the present application, the second magnetic member 123A can be wrapped in the float 123, and the material of the float 123 can be selected from a food-grade material. The density of the float 123 is less than the density of the milk, so that the milk can float the float 123 and the second magnetic member 123A together, and the float 123 can rise or fall along with the change of the height of the milk liquid surface L.

[0335] Please refer to FIG. 14, in some embodiments of the present application, the first magnetic member 124A is arranged on the inner wall of the container main body 11.

[0336] By setting the first magnetic member 124A on the inner wall of the container body 11, the first magnetic member 124A is closer to the second magnetic member 123A, thereby improving the adsorption effect of the first magnetic member 124A on the second magnetic member, improving the reliability of the guiding assembly 124 guiding the float 123, and improving the effect of the damping device 12 reducing the shock of the milk, so that the amount of milk in the container body 11 and the liquid level of the milk detected by the liquid level detection unit in the breast pump 1 are more accurate and reliable. The first magnetic member 124A can be wrapped with food-grade materials such as silica gel sleeves to prevent the first magnetic member 124A from contaminating the milk.

[0337] Please refer to FIG. 15, in some embodiments of the present application, the first magnetic member 124A is arranged on the outer wall of the container body 11.

[0338] By arranging the first magnetic member 124A on the outer wall of the container body 11, the first magnetic member 124A is prevented from contaminating the milk in the container body 11.

[0339] In some embodiments of the present application, the first magnetic member 124A can include an electromagnet.

[0340] By changing the current of the electromagnet, the magnetic attraction of the first magnetic member 124A can be adjusted, so that the magnetic attraction of the first magnetic member 124A to the second magnetic member 123A is adjustable. By adjusting the magnetic attraction of the first magnetic member 124A to the second magnetic member, the size of the magnetic attraction of the first magnetic member 124A to the second magnetic member ensures that the float 123 can be reliably adsorbed by the first magnetic member 124A while rising or falling with the change of the milk liquid level L, reducing the risk of the float 123 separating from the guiding assembly 124, thereby improving the reliability of the damping device 12 reducing the shock of the milk.

[0341] Please refer to FIG. 16, in some embodiments of the present application, the guiding assembly 124 includes a spring member 124C. One end of the spring member 124C is connected to the float 123, and the other end of the spring member 124C is connected to the bottom of the container body 11. The length of the spring member 124C after elastic deformation is equal to the distance from the milk liquid level L to the bottom of the container body 11, so that the float 123 moves with the change of the milk liquid level L under the guidance of the spring member 124C.

[0342] The floating block 123 is pulled by the spring member 124C which can be elastically deformed, so that the floating block 123 is subjected to the milk floating force and the elastic force of the spring member 124C. When the floating block 123 floats on the milk liquid surface L, the floating block 123 pulls the spring member 124C, and the spring member 124C is elastically deformed, and the spring member 124C pulls the floating block 123 from below the milk liquid surface L, and the elastic force generated by the elastic deformation limits the moving range of the floating block 123 along the milk liquid surface L, and reduces the fluctuation range of the floating block 123, so that the floating block 123 pulls the milk through the tension of the milk liquid surface L, and on the other hand, hinders the propagation of the shock wave along the milk liquid surface L generated by the milk shock. The spring member 124C which is elastically deformed can absorb more energy of the shock wave due to its own elastic force. In this way, the effect of the shock absorption device 12 on weakening the milk shock is improved, so that the data such as the amount of milk and the liquid level of milk in the container main body 11 detected by the liquid level detection unit in the breast pump 1 is more accurate and reliable.

[0343] Embodiment Three

[0344] Please refer to FIG. 17 to FIG. 18, in some embodiments of the present application, the shock absorption device 12 comprises at least one partition 125, and the partition 125 divides the container main body 11 into at least two chambers 111, and the chambers 111 are in communication with each other.

[0345] The container main body 11 is divided into multiple chambers 111 by the partition 125, so as to reduce the energy transmission between the milk in the container main body 11, thereby weakening the shock of the milk in each chamber 111 of the container main body 11. In addition, the chambers 111 of the container main body 11 are in communication with each other, so that the milk in the container main body 11 has a unified milk liquid surface L, thereby ensuring the accuracy and reliability of the data such as the amount of milk and the liquid level of milk in the container main body 11 detected by the liquid level detection unit.

[0346] Please refer to FIG. 17, in some embodiments of the present application, the chambers 111 are arranged in sequence in the transverse direction, and the adjacent chambers 111 are in communication at the top and bottom of the container main body 11.

[0347] The chambers 111 are arranged in sequence in the transverse direction, that is, the container main body 11 is divided into longitudinally arranged chambers 111 by the longitudinally arranged partition 125, and the chambers 111 are in communication at the top and bottom of the container main body 11. Wherein, the longitudinal direction refers to the direction from the bottom to the top of the container main body 11, and the transverse direction refers to the direction perpendicular to the longitudinal direction.

[0348] By longitudinally arranging the chambers 111 and transversely arranging the chambers 111 in sequence, the milk surface L is divided into multiple regions by the partitions 125, and the transmission of the shock waves between the regions of the milk surface L is blocked by the partitions 125, thereby improving the effect of the shock attenuation device 12 on weakening the milk shock. By communicating the chambers 111 from the bottom of the container body 11, the consistency of the height of the milk level between the chambers 111 is ensured. By communicating the chambers 111 at the top of the container body 11, the air pressure between the chambers 111 is balanced, thereby enabling the milk to be uniformly distributed in the chambers 111, further ensuring the consistency of the height of the milk level between the chambers 111, and making the data detected by the liquid level detection unit in the breast pump 1 more accurate and reliable.

[0349] In some embodiments of the present application, the partitions 125 are provided with mesh holes, and the flow of the milk between the chambers 111 is improved by densely arranging the mesh holes in the partitions 125. When the shock occurs, the milk can flow between the chambers 111 through the mesh holes, thereby ensuring the consistency of the change of the milk level between the chambers 111, and making the data detected by the liquid level detection unit in the breast pump 1 more accurate and reliable. After the milk passes through the mesh holes, the energy of the milk shock can be effectively reduced by the blocking of the partitions 125, thereby making the flow of the milk more gentle, so that the shock attenuation device 12 can weaken the milk shock.

[0350] Please refer to FIG. 18. In some embodiments of the present application, the chambers 111 are arranged longitudinally in sequence, and the shock attenuation members 114 between the chambers 111 are arranged at the side of the chambers 111, and the adjacent shock attenuation members 114 are arranged at the two sides of the chambers 111, respectively, so that the milk flows in the transverse direction.

[0351] The chambers 111 are arranged longitudinally in sequence, that is, the internal space of the container body 11 is divided into a multi-layer cavity structure by the transversely arranged partitions 125. By arranging the shock attenuation members 114 between the chambers 111 at the side of the chambers 111, and arranging the adjacent shock attenuation members 114 at the two sides of the chambers 111, respectively, the milk flows in the transverse direction.

[0352] When the milk enters the container body 11, the milk passes through the shock absorber 114 from the higher layer chamber 111 to the chamber 111 of the layer where the milk level L is located, so as to raise the milk level L. When the shock occurs, the resistance of the milk flow is increased by the partition 125 below the milk level L, the shock of the milk level L is limited by the partition 125 in contact with the milk level L, and the peak height of the shock wave in the milk level L is limited by the partition 125 above the milk level L. In this way, the effect of the shock absorber 12 on weakening the shock of the milk is improved, so that the data such as the amount of milk in the container body 11 and the milk level detected by the milk level detection unit in the breast pump 1 are more accurate and reliable.

[0353] In some embodiments of the present application, the partition 125 is provided with a mesh, and the container body 11 is divided into chambers 111 arranged longitudinally in sequence by the mesh of the partition 125. The mesh of the partition 125 avoids the milk being blocked by the partition 125 from the inside of the container body 11, and facilitates the complete discharge of the milk in the container body 11 when the milk is poured out.

[0354] In some embodiments of the present application, the container body 11 is provided with a milk pouring port 112, and the container body 11 is provided with a shock absorber 121 arranged inside the milk pouring port 112 to prevent the milk in the container body 11 from splashing out of the milk pouring port 112.

[0355] When the shock occurs, the shock absorber 121 blocks the milk splashing out of the milk pouring port 112 due to the shock.

[0356] When the height of the milk level L in the container body 11 approaches the milk pouring port 112, the shock absorber 121 prevents the milk from reaching the side of the shock absorber 121 close to the milk pouring port 112 due to the shaking, thereby preventing the milk from hanging on the wall or irregularly shaking, which affects the accuracy of the milk volume detection.

[0357] In some embodiments of the present application, the shape of the shock absorber 121 is arc-shaped, and the top of the shock absorber 121 is away from the milk pouring port 112.

[0358] By making the shape of the shock absorber 121 arc-shaped and the top of the shock absorber 121 away from the milk pouring port 112, the milk flows along the two sides of the shock absorber 121 to the milk pouring port 112 during the process of pouring the milk out of the milk pouring port 112, and the external contaminants are prevented from entering the container body 11 through the milk pouring port 112 to contaminate the milk. When the contaminants enter the container body 11 through the milk pouring port 112, the shock absorber 121 blocks the contaminants, and the arc-shaped concave structure limits the movement of the external contaminants, so that the user can clean the contaminants.

[0359] By making the top of the damping piece 121 away from the teat cup 112, the milk will flow along the damping piece 121 to the teat cup 112 during the teat cup process, thereby making the teat cup process more smooth.

[0361] In some embodiments, the breast shield 31 is used to cover the human breast and fit the breast, and the breast shield 31 comprises a flared flange 311 for fitting the breast and a nipple receiving portion 312 for receiving the nipple.

[0362] In some embodiments, the nipple receiving portion 312 surrounds a nipple passage 34, and the nipple passage 34 is used to receive the nipple when the user wears the breast pump 1.

[0363] In some embodiments, the milk storage container 10 is used to receive and store the breast milk collected by the breast shield 31, and the milk storage container 10 is in communication with the breast shield 31.

[0364] Optionally, the milk storage container 10 comprises a milk cover, a milk bowl, a milk bottle and the like, which are not limited by the present application.

[0365] In some embodiments, the main machine 20 comprises a negative pressure mechanism 22, a main machine shell 21 and a display screen D.

[0366] In some embodiments, the negative pressure mechanism 22 is used to directly or indirectly apply negative pressure to the breast shield 31 to suck the breast milk into the milk storage container 10.

[0367] Optionally, the negative pressure mechanism 22 comprises but is not limited to a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump and the like.

[0368] Optionally, the negative pressure mechanism 22 can be directly communicated with the breast shield 31 to cause negative pressure inside the breast shield 31, or can indirectly cause negative pressure inside the breast shield 31 by transmitting negative pressure to a diaphragm assembly or a liquid barrier such as an air bag.

[0369] In some embodiments, the negative pressure mechanism 22 is at least partially arranged in the main machine shell 21, and the main machine shell 21 can further comprise an energy supply module, a negative pressure gas circuit, a control circuit board, a solenoid valve and the like.

[0370] Optionally, the energy supply module is used to provide energy for the negative pressure mechanism 22 to support the work of the negative pressure mechanism 22.

[0371] In some embodiments, the breast pump further comprises an image acquisition device C configured to acquire at least an image of the nipple passage 34 formed by the nipple accommodating portion 312.

[0372] In some embodiments, the image acquisition device C comprises one of a camera, a video camera, and a thermal imager.

[0373] As shown in FIG. 21, in some embodiments, the image acquisition device C is arranged in the host housing 21 of the host 20; however, it is to be understood that the present application is not limited thereto, and the image acquisition device C can be arranged separately from the host 20 and detachably connected to the host 20.

[0374] As shown in FIG. 21, in some embodiments, the image acquisition device C acquires images along the axial direction of the nipple passage.

[0375] Specifically, it is necessary to determine whether the user wears the breast pump correctly according to the images acquired by the image acquisition device C, and when the nipple is located in the central region of the nipple passage, it can be considered that the user wears correctly, and thus it is necessary to determine the position of the nipple in the nipple passage. The image acquisition device C acquires images along the axial direction of the nipple passage, which can make the acquired images more clearly reflect the position of the nipple in the nipple passage, and improve the accuracy of determining whether the user wears correctly.

[0378] When the image acquisition device C is arranged in the host housing 21, the image acquisition device C can not be easily disassembled, and thus it is difficult to clean the lens of the image acquisition device C when dust accumulates on the lens. By arranging the transparent piece T, dust can be blocked and prevented from accumulating on the lens of the image acquisition device C.

[0379] In some embodiments, the host housing 21 is provided with an opening, and the image acquisition device acquires images through the opening; for example, the transparent piece T in FIG. 22 can not be arranged, and the opening is present at the position where the transparent piece T is originally arranged.

[0380] By arranging the opening, the clarity of the images obtained by shooting can be improved because there is no object to block.

[0381] In some embodiments, the image acquisition device is not limited to collecting images along the axis of the nipple passage, please refer to FIG. 23, which is a second structural schematic diagram of the breast pump provided by the embodiments of the present application.

[0391] In some embodiments, the display module comprises a nipple alignment identification area to assist the user to align the nipple, and the breast pump is correctly worn when the nipple is located in the nipple alignment identification area.

[0392] By displaying the nipple alignment identification area, when the user's nipple is located in the nipple alignment identification area, it can be reflected that the breast pump is correctly worn, and the comfort of the breast pump during the suction process of the breast pump is ensured.

[0393] In some embodiments, the display module includes a nipple identification area for identifying the nipple.

[0394] By identifying the nipple through the nipple identification area, the observer can quickly locate the position of the nipple, which is conducive to subsequent judgment of whether the breast pump is correctly worn.

[0395] In some embodiments, the display module includes a nipple passage edge area for identifying the edge of the entire nipple passage.

[0396] By identifying the edge of the nipple passage through the nipple passage edge area, it is conducive for the user to subsequently judge whether the breast pump is correctly worn, for example, if the edge of the nipple is outside the edge of the nipple passage, the breast groove can be squeezed outside the passage.

[0397] Please refer to FIG. 24, which is a first schematic diagram of a nipple alignment identification area provided by an embodiment of the present application. As shown in FIG. 24, the image I obtained by the image acquisition device includes a nipple receiving portion R1, a mammary gland R2, an areola R3, and a nipple R4.

[0406] In some embodiments, the nipple passage edge area described above is also shown in FIGS. 25 and 26, and the nipple passage edge area includes a dashed line L1. When the center of the circle composed of the dashed line L3 and the center of the circle composed of the dashed line L1 are located at the same position or the distance between the two centers is less than a preset distance, it represents that the user wears the breast pump correctly.

[0407] For example, FIG. 25 is a schematic diagram of the user wearing the breast pump correctly, and FIG. 26 is a schematic diagram of the user not wearing the breast pump correctly.

[0408] In some embodiments, a center point (not shown in the figure) is also shown in FIGS. 25 and 26. When the circle composed of the dashed line L3 includes the center point, it represents that the user wears the breast pump correctly.

[0409] Through the above setting, whether the user wears the breast pump correctly can be identified through image recognition. When the user wears the breast pump, he cannot see whether his nipple is worn in the correct direction or position in the breast shield in the breast pump, which may cause the user to be in pain or the efficiency of breast pumping to be low during subsequent breast pumping.

[0410] In some embodiments, the breast pump further includes a processing unit, which is communicatively connected to the image acquisition device C, is used to acquire the image collected by the image acquisition device C, and identify the positional relationship between the nipple and the breast shield 31 according to the image.

[0411] In some embodiments, the positional relationship includes whether the nipple enters the nipple passage or whether the nipple is located in a preset area in the nipple passage.

[0412] In some embodiments, the distance between the nipple and the image acquisition device can be determined according to the size of the nipple in the image, thereby indirectly determining the distance between the nipple and the end of the breast shield. When the distance between the nipple and the end of the breast shield is less than a preset distance, it can be determined that the nipple enters the nipple passage.

[0413] In some embodiments, the positional relationship further includes whether the nipple is located in the center area of the nipple passage.

[0414] In some embodiments, the processing unit can identify the edge of the nipple containing portion according to the image, and the area in the image other than the nipple containing portion is determined as the nipple passage, so as to determine whether the nipple is located in the center area of the nipple passage.

[0415] Optionally, a frame selection control can be provided on the display module, and the user can operate the frame selection control to frame the area where the nipple is located for the processing unit to identify the positional relationship between the nipple and the breast shield.

[0416] Through the above arrangement, the processing unit of the breast pump can identify the positional relationship between the nipple and the breast shield according to the image, so as to determine whether the user wears the breast pump correctly through the program.

[0417] In some embodiments, the processing unit is further configured to identify the outer edge of the nipple in the image according to the image, and form a nipple edge area.

[0418] In some embodiments, the nipple can be identified by color in the image, and the outer edge of the nipple is determined after the nipple is identified.

[0419] Specifically, the breast includes a mammary gland, an areola and a nipple, and the mammary gland, the areola and the nipple have different colors respectively, and the area where the nipple is located can be identified by color to determine the wearing position.

[0420] Specific arrangements will be described in the following part of the specification.

[0421] In some embodiments, a frame selection control can be provided on the display module, and the user can operate the frame selection control to frame the area where the nipple is located for the processing unit to identify the outer edge of the nipple.

[0429] Specifically, a plurality of images captured by the image acquisition device can be acquired, and the artificial intelligence model is trained by the plurality of images to identify the nipple accommodating portion and the non-nipple accommodating portion.

[0430] Specifically, the breast includes a mammary gland, an areola and a nipple, and the mammary gland, the areola and the nipple have different colors respectively, and the region where the nipple is located can be identified by color to determine the wearing position.

[0431] In some embodiments, the preset condition includes that the RGB value of the color is in a preset range.

[0433] In some embodiments, after the region where the nipple is located is identified, the two-dimensional coordinates of the nipple in the image can be identified, and then the step of determining the distance of the nipple from the reference object according to the area area of the region where the nipple is located is performed as the longitudinal coordinate of the nipple, and the two-dimensional coordinates and the longitudinal coordinate constitute the wearing coordinates of the nipple, that is, the wearing position of the nipple.

[0434] Optionally, the breast pump pre-stores a corresponding relationship table of the area area of the region where the nipple is located and the distance from the reference object.

[0435] Optionally, the reference object includes an end of the breast shield, an image acquisition device, etc., which is not limited in the present application.

[0436] Step 330: performing a preset operation according to the wearing position.

[0437] In some embodiments, the control method of the breast pump provided by the embodiments of the present application further includes step 330: performing a preset operation according to the wearing position.

[0438] In some embodiments, step 330 includes the following steps.

[0439] (1) When the wearing position does not satisfy the correct wearing condition, determining a calibration direction according to the wearing position.

[0444] identifying the nipple channel edge region according to the image to determine the center coordinate of the nipple channel formed by the nipple accommodation part;

[0445] determining the calibration direction according to the nipple center point coordinate and the center coordinate of the nipple channel.

[0446] The calibration direction is directed from the nipple center point coordinate to the center coordinate of the nipple channel.

[0447] In this way, the wearing position of the breast shield can be automatically calibrated when the breast shield is incorrectly worn, and the intelligent level of the breast pump is improved.

[0448] In some embodiments, step 330 comprises the following steps.

[0449] (1) determining whether the wearing position meets the correct wearing condition, and issuing one or more of the following: sound prompt, somatosensory prompt, and visual prompt according to the determination result.

[0450] In some embodiments, step 330 comprises the following steps.

[0453] Optionally, the sound prompt comprises one of the following: voice prompt and ring prompt.

[0454] For example, the ring prompt corresponding to correct wearing is one "drop", and the ring prompt corresponding to incorrect wearing is three consecutive "drops".

[0455] For example, the sound prompt corresponding to correct wearing is "correct wearing", and the sound prompt corresponding to incorrect wearing is "incorrect wearing". Further, the sound prompt can comprise adjustment instructions, such as "incorrect wearing, please adjust to the upper right".

[0456] Optionally, the somatosensory prompt comprises vibration of the breast pump or vibration of a controller matched with the breast pump.

[0457] Optionally, the visual prompt includes a light on the breast pump turning on, a display screen of the breast pump displaying that the breast cup is worn incorrectly or correctly, and the like.

[0458] In some embodiments, the method further includes: when the wearing position changes, re-determining whether the wearing position meets the correct wearing condition.

[0459] In some embodiments, the user manually adjusts the wearing position of the breast pump according to the issued prompt, and the wearing position is continuously monitored, and when the wearing position changes, the correct wearing condition is re-determined until the user wears correctly.

[0460] In this way, the user can be assisted to manually adjust the breast pump to the correct wearing position.

[0461] In some embodiments, the correct wearing condition includes that the distance between the wearing position and the standard position is less than or equal to a preset distance, or the wearing position is within a correct wearing area.

[0479] In summary, the present application provides a control method and device of a breast pump, a breast pump, and a storage medium. The breast pump includes a breast shield, a milk storage container, and a main machine. The breast shield includes a flange for fitting a breast and a nipple receiving portion for receiving a nipple. The milk storage container is used to receive and store breast milk collected by the breast shield, and is in communication with the breast shield. The main machine includes a negative pressure mechanism for directly or indirectly applying negative pressure to the breast shield to suck breast milk into the milk storage container. The breast pump further includes an image acquisition device for acquiring at least an image of a nipple passage formed by the nipple receiving portion. The present application acquires an image of a nipple passage formed by the nipple receiving portion through the image acquisition device, and reflects the wearing condition of the user when wearing the breast pump or the wearing condition after wearing through the image, thereby facilitating the user to correctly wear the breast pump.

[0480] The present application provides a breast pump 1, please refer to FIG. 31, which is integrated as a whole by assembling a plurality of separate components. The components of the breast pump 1 include a shield assembly 30, a main machine 20, and a milk storage container 10. The shield assembly 30 is used to suck milk from the breast of a user, and includes a breast shield 31, a milk passage portion 32, and a support frame 33 in communication with the milk passage portion 32. The main machine 20 includes an air pump 221 for providing negative pressure to the shield assembly 30, a processor 510 for controlling the operation of the air pump 221, and an anti-backflow barrier 23. The milk storage container 10 is used to store the milk sucked out of the shield assembly 30.

[0481] In the assembly of the breast pump 1, assembly gaps exist between the components during assembly. In order to avoid leakage and ensure the safety and stability of the breast pump, the assembly gaps between the components need to be sealed.

[0482] As shown in Figures 31-33, in one embodiment of the breast pump 1 of the present application, the milk storage container 10 is assembled to the shield assembly 30, and the shield assembly 30 is assembled to the main unit 20. In order to achieve the sealing between the milk bowl 13 and the breast shield 31, and the sealing between the support frame 33 and the anti-backflow barrier 23, the breast pump 1 of this embodiment further comprises an elastic sealing member for sealing the assembly gap G.

[0483] Please refer to Fig. 31, an elastic sealing member is arranged between the milk bowl 13 and the breast shield 31. Specifically, after the milk bowl 13 and the breast shield 31 are assembled, there is an assembly gap G between the milk bowl 13 and the breast shield 31, and the elastic sealing member is arranged in the assembly gap G between the milk bowl 13 and the breast shield 31. The elastic sealing member seals the assembly gap G between the milk bowl 13 and the breast shield 31, i.e. ensures the sealing effect between the milk bowl 13 and the breast shield 31, thereby avoiding the problem of liquid or gas leakage between the milk bowl 13 and the breast shield 31. Specifically, as shown in Fig. 32, the elastic sealing member includes a guide sealing part 711, which is located between the milk bowl 13 and the breast shield 31, and includes a first side edge LA1 and a second side edge LB1. The first side edge LA1 forms a first included angle α1 with the breast shield 31, and the second side edge LB1 forms a second included angle α2 with the side edge of the breast shield 31. The first included angle α1 is directed towards the moving direction of the milk bowl 13 when it is assembled into the breast shield 31, and the second included angle α2 is directed towards the moving direction of the milk bowl 13 when it is disassembled from the breast shield 31. When the elastic sealing member seals the assembly gap G between the milk bowl 13 and the breast shield 31, the first side edge LA1 is in contact with and compressed by the inner inclined wall of the breast shield 31, and the second side edge LB1 is in contact with and compressed by the other vertical inner wall of the breast shield 31. At this time, the guide sealing part 711 will deform with the assembly of the milk bowl 13 to the breast shield 31, i.e. the first side edge LA1 deforms after abutting against the side wall of the breast shield 31, so that the angle of the first included angle α1 increases, and the second side edge LB1 deforms with the deformation of the first side edge LA1, so that the angle of the second included angle α2 decreases. When the elastic sealing member is assembled into the breast shield 31 with the milk bowl 13, the angles of the first included angle α1 and the second included angle α2 stop changing, at this time the assembly gap G between the milk bowl 13 and the breast shield 31 is sealed, the first included angle α1 is obtuse, and the second included angle α2 is a right angle. A third side edge LC1 is arranged between the first side edge LA1 and the second side edge LB1, which connects the first side edge LA1 and the second side edge LB1, so that the guide sealing part 711 is more closely attached to the inner wall of the breast shield 31 as a whole.

[0484] In this embodiment, the elastic sealing member is integrally formed with the milk bowl 13. Of course, in other embodiments of the present application, the elastic sealing member can be arranged on a separate detachable connecting member, which is detachably connected to the milk bowl 13 or the breast shield 31.

[0485] As shown in FIG. 33, in this embodiment, an elastic sealing piece is arranged between the support frame 33 and the anti-backflow barrier 23 to seal the assembly gap G between the support frame 33 and the anti-backflow barrier 23; in this embodiment, the elastic sealing piece is connected with the support frame 33 and seals the assembly gap G between the support frame 33 and the anti-backflow barrier 23 during the assembly and support of the support frame 33 on the anti-backflow barrier 23, that is, to ensure the sealing effect of the support frame 33 and the anti-backflow barrier 23, thereby avoiding the problem of liquid or gas leakage between the support frame 33 and the anti-backflow barrier 23. Specifically, the first included angle a3 is directed to the moving direction of the support frame 33 when being assembled into the anti-backflow barrier 23, and the second included angle a4 is directed to the moving direction of the support frame 33 when being disassembled from the anti-backflow barrier 23; when the elastic sealing piece seals the assembly gap G between the support frame 33 and the anti-backflow barrier 23, the first side LA2 is arranged to be spaced apart from the inner side wall of the anti-backflow barrier 23, and the second side LB2 is in abutment with and is forced to compress the other vertical inner side wall of the anti-backflow barrier 23; at this time, the guide sealing part 712 will be deformed along with the assembly of the support frame 33 on the anti-backflow barrier 23, that is, the first side LA2 is deformed by abutting on the side wall of the anti-backflow barrier 23, so that the angle of the first included angle a3 is increased, and the second side LB2 is deformed along with the deformation of the first side LA2, so that the angle of the second included angle a4 is decreased; when the elastic sealing piece is assembled with the support frame 33 and the anti-backflow barrier 23, the angles of the first included angle a3 and the second included angle a4 are both stopped from changing, at this time, the assembly gap G between the support frame 33 and the anti-backflow barrier 23 is sealed, the first included angle a3 is an obtuse angle, the second included angle a4 is a right angle, and the third side LC2 is arranged between the first side LA2 and the second side LB2, the third side LC2 is arranged in an arc shape, the first side LA2 and the second side LB2 are connected by the third side LC2, so that the guide sealing part 712 is more closely attached to the inner side wall of the breast shield 31 as a whole.

[0486] In this embodiment, the elastic sealing pieces are arranged between the milk bowl and the breast shield and between the support frame and the anti-backflow barrier. It can be understood that in other embodiments of the present application, the elastic sealing pieces can be arranged only between the milk bowl and the breast shield or only between the support frame and the anti-backflow barrier, of course, the breast pump of the present application can also arrange elastic sealing pieces between other assembled parts. The present application arranges elastic sealing pieces between different assembled parts, which is not limited.

[0487] Optionally, the anti-backflow barrier 23 in the above embodiments can be provided as a suction cup or a suction diaphragm. The suction cup is an important component of the breast pump 1, and its main function is to generate negative pressure to assist in breast pumping. Meanwhile, the suction diaphragm is a diaphragm located inside the breast pump 1, which usually works with the air pump 221 to generate deformation of the diaphragm through negative pressure generated by the pump, and then generates suction force in the breast pumping part of the breast pump 1.

[0488] As shown in FIG. 34, another embodiment of the breast pump provided by the present application is shown, which includes a milk storage container 10 including a milk cup 13 and a milk cup cover 14 detachably mounted on the milk cup 13. An elastic sealing member 74 is arranged between the milk cup 13 and the milk cup cover 14 to seal the assembly gap G between the milk cup 13 and the milk cup cover 14. In this embodiment, the elastic sealing member 74 is connected with the milk cup cover 14 and seals the assembly gap G between the milk cup 13 and the milk cup cover 14 during the process of covering the milk cup 13 by the milk cup cover 14. Specifically, the first side edge LA3 forms a first included angle a5 with one of the side walls of the milk cup cover 14, and the second side edge LB3 forms a second included angle a6 with the line on which the other side wall of the milk cup cover 14 lies. The first included angle a5 is directed towards the moving direction of the milk cup 13 when being assembled into the milk cup cover 14, and the second included angle a6 is directed towards the moving direction of the milk cup 13 when being disassembled from the milk cup cover 14. When the elastic sealing member 74 seals the assembly gap G between the milk cup 13 and the milk cup cover 14, the first side edge LA3 is arranged in abutment with and is pressed against the vertical inner side wall of the milk cup 13 to be compressed under stress, and the second side edge LB3 is deformed along with the first side edge LA3 to be compressed under stress. At this time, the guide sealing part 713 is deformed along with the assembly process of the milk cup 13 and the milk cup cover 14, the first side edge LA3 is deformed by abutting against the side wall of the milk cup 13, so that the angle of the first included angle a5 is increased, and the second side edge LB3 is deformed along with the deformation of the first side edge LA3, so that the angle of the second included angle a6 is decreased. When the elastic sealing member 74 is assembled with the milk cup 13 and the milk cup cover 14, the angles of the first included angle a5 and the second included angle a6 stop changing, at this time, the assembly gap G between the milk cup 13 and the milk cup cover 14 is sealed, the first included angle a5 is an obtuse angle, and the second included angle a6 is a right angle. A third side edge LC4 is arranged between the first side edge LA3 and the second side edge LB3 to connect the first side edge LA3 and the second side edge LB3, so that the guide sealing part 713 is more closely attached to the inner side wall of the milk cup 13.

[0489] In the above-mentioned three different embodiments, the elastic sealing member is connected to the breast cup cover 14, the breast shield 31 and the support frame 33, respectively, so that the elastic sealing member can seal the assembly gap together with the first assembly part of the three parts, and the elastic sealing member is not installed as a separate part. In some embodiments, the elastic sealing member is detachably connected to the three assembly parts, so that the user can take out the breast pump sealing structure for cleaning, replacement, maintenance and other operations, thereby improving the convenience. In other embodiments, the elastic sealing structure is integrally formed with the three second assembly parts, so that the breast pump can simplify the processing and installation process during production, thereby improving the processing efficiency of the breast pump.

[0490] It can be understood that the elastic sealing member is made of a silicone material, and the breast cup cover is made of a relatively hard PP material or an ABS material. The PP material is a transparent plastic. In the present embodiment, the elastic sealing member and the three assembly parts can be integrally formed or the elastic sealing member can be installed on the three assembly parts. By designing two different assembly methods, the elastic sealing member and the assembly parts can be assembled and connected, which can be suitable for different structures of the breast pump to meet various application scenarios of the breast pump.

[0491] Please refer to FIGS. 36-40 for various structures of the sealing structure. The sealing structure of each different structure can be implemented in a breast pump with different structures to seal different assembly parts of the breast pump. In the present application, the sealing structure 70 includes a first assembly part 72, a second assembly part 73 and an elastic sealing member 75 arranged between the first assembly part 72 and the second assembly part 73. When the first assembly part 72 and the second assembly part 73 are assembled, there is an assembly gap J between them, and the elastic sealing member 75 is used to seal the assembly gap, so that the first assembly part 72 and the second assembly part 73 are sealed. It can be understood that the first assembly part 72 can be one of the breast cup 13, the elastic sealing member 74, the anti-backflow barrier 23, the breast cup cover 14, the breast shield 31, the anti-backflow barrier 23 and the support frame 33, and the second assembly part can be another one of the breast cup 13, the elastic sealing member 74, the anti-backflow barrier 23, the breast cup cover 14, the breast shield 31, the anti-backflow barrier 23 and the support frame 33 that cooperates with the first assembly part.

[0492] Please refer to FIG. 36-FIG. 37, in an embodiment of the sealing structure of the present application, the elastic sealing member 75 includes a guide sealing portion 714. The guide sealing portion 714 includes a first side LA4 and a second side LB4, the first side LA4 forms a first included angle α7 with the second assembly member 73, and the second side LB4 forms a second included angle α8 with the second assembly member 73; wherein the first included angle α7 is towards the moving direction V1 of the first assembly member 72 when assembling, and the second included angle α8 is towards the moving direction V2 of the first assembly member 72 when disassembling; in this embodiment, the first direction V1 is defined as the moving direction of the first assembly member 72 when assembling, and the second direction V2 is defined as the moving direction of the first assembly member 72 when disassembling; the first included angle α7 is obtuse, and the second included angle α8 is a right angle; when the first assembly member 72 and the second assembly member 73 are not assembled, the guide sealing portion 714 as a whole is inclined towards the moving direction V1 of the first assembly member 72 when assembling into the second assembly member 73 or the moving direction V2 when disassembling, and the purpose of setting this structure is to make the guide sealing portion 714 more easily fit into the assembly gap G between the first assembly member 72 and the second assembly member 73 when the first assembly member 72 is assembled into the second assembly member 73, and when the first assembly member and the second assembly member are assembled, the guide sealing portion 714 is inclined towards the moving direction V1 of the first assembly member 72 when assembling, the first side LA4 of the guide sealing portion 714 forms an extension surface, and the second side LB4 forms a compression surface; and during the process of assembling the first assembly member into the second assembly member, the angle of the first included angle α7 increases, and the angle of the second included angle α8 decreases. Thus, the guide sealing portion forms an elastic force to press the first assembly member, and at the same time, the first assembly member generates a plastic deformation force to the guide sealing portion, which makes the guide sealing portion deform, thereby facilitating the sealing effect of the elastic sealing member, and at the same time, making the required force greater when disassembling the first assembly member, which is more conducive to avoiding the disassembly of the first assembly member.

[0493] In this embodiment, the cross section of the guide sealing portion 714 is a triangle, and is a right triangle, the first included angle α7 is obtuse, and the second included angle α8 is 90 degrees, the first side LA4 and the second side LB4 are connected and form an acute angle therebetween. Of course, in other embodiments of the present application, the second included angle α8 is not limited to a right angle, and can be less than 90 degrees; it can also be less than and / or equal to the angle of the first included angle α7, and the purpose of setting this structure is to make the structure of the guide sealing portion more suitable for the structure between the installed first assembly member and / or second assembly member, so that different structure guide sealing portion breast pump products can be designed to meet the different use requirements and use scenarios of users.

[0494] In other embodiments of the present application, as shown in FIG. 38, the first included angle a9 of the guide sealing portion 715 has an angle greater than 90°, the second included angle a10 has an angle equal to that of the first included angle a9, and the first side LA5 and the second side LB5 are connected and form an acute angle therebetween.

[0495] In other embodiments of the present application, as shown in FIG. 39, a third side LC3 can also be arranged between the first side LA6 and the second side LB6, and the first side LA6 and the second side LB6 are connected through the third side LC3.

[0496] In other embodiments of the present application, as shown in FIG. 40, the first side LA7 and the second side LB7 are arc-shaped, and the cross section of the guide sealing portion 716 is crescent-shaped. The first included angle a13 has an angle greater than 90°, and the second included angle a14 has an angle less than 90°.

[0497] The elastic sealing member has better sealing effect. The guide sealing portion has different inclination structures of the first included angle and the second included angle, so that the extrusion force of the first assembly and the second assembly after assembly is increased, the deformation amount is increased, and the falling of the first assembly can be effectively avoided.

[0498] In summary, the present application provides a breast pump sealing structure and a breast pump. The elastic sealing member is arranged between the first assembly and the second assembly, and the elastic sealing member includes a guide sealing portion. The assembly gap between the first assembly and the second assembly is sealed, the influence of the assembly process on the sealing effect is prevented, the problems such as liquid leakage or gas leakage of the first assembly and the second assembly are avoided, and the use safety and performance stability of the breast pump are ensured.

When the movement of the main unit 20 or the milk storage container 10 reaches a preset position or travel, the two contacts in the travel switch 411 are in contact, the travel switch 411 is powered on, and the travel switch 411 is triggered.

[0529] In some embodiments, the travel switch 411 can be referred to as a limit switch, a push detection switch, a micro travel switch, a micro key switch, a micro detection switch, or a micro detection key switch, etc.

[0530] The travel switch 411 included in the first detection device 41 is described in detail below.

[0533] Optionally, the trigger portion 4111 can be an elastic component, such as a spring, etc.

[0534] Optionally, the travel switch 411 can have a push rod, a spring, and a moving-break contact. The spring can be arranged around the push rod and control the push rod to keep in contact with the moving-break contact in the absence of external force. At this time, when the moving-break contact is not electrically connected with the control module 810, the travel switch 411 is disconnected, i.e., the travel switch 411 is not powered on; when the moving-break contact is electrically connected with the control module 810, the travel switch 411 is powered on.

[0535] Optionally, the travel switch 411 can have a push rod, a spring, and a moving-make contact. When the host 20 is correctly assembled with the milk storage container 10, the push rod is compressed to a preset position, at which time the push rod contacts the moving-make contact. When the moving-make contact is electrically connected with the control module 810, the travel switch 411 is triggered, the circuit passing through the travel switch 411 is turned on, and an electrical signal is generated.

[0536] Optionally, the travel switch 411 can have a push rod, a spring, a moving-break contact, and a moving-make contact.

[0537] Optionally, when the host 20 is correctly assembled with the milk storage container 10, the trigger portion 4111 is compressed, and the travel switch 411 is triggered. At this time, the push rod contacts the moving-make contact, the travel switch 411 is triggered, the circuit passing through the travel switch 411 is turned on, and an electrical signal is generated. In this embodiment, the moving-break contact is not electrically connected with the control module 810.

[0538] Optionally, when the host 20 is not correctly assembled with the milk storage container 10, the trigger portion 4111 is not compressed, and the travel switch 411 is triggered. At this time, the push rod keeps in contact with the moving-break contact, the moving-break contact is electrically connected with the control module 810, and the travel switch 411 is powered on. In this embodiment, the moving-make contact is not electrically connected with the control module 810.

[0539] At this time, the trigger portion in the first detection device 41 is the trigger portion 4111 in the travel switch 411.

[0540] As shown in FIGS. 43 and 44, in some embodiments, the travel switch 411 is installed in the host 20, and the surface of the host 20 facing the milk storage container 10 is provided with a first through hole 211 for the trigger portion 4111 to pass through.

[0541] As shown in FIG. 44, the trigger portion 4111 is optionally extended from the main body 20 towards the surface of the milk storage container 10 through the first through hole 211, and when the main body 20 is assembled with the milk storage container 10, the surface of the milk storage container 10 is close to the main body 20, and the surface of the milk storage container 10 will compress the trigger portion 4111.

[0542] In the above manner, when the main body 20 is assembled with the milk storage container 10, the distance that the trigger portion 4111 is compressed can be increased, thereby improving the accuracy of determining whether the main body 20 is correctly assembled with the milk storage container 10.

[0543] In other embodiments, the surface of the milk storage container 10 can have a structure matching the first through hole 211.

[0544] Please refer to FIG. 45 and FIG. 46, FIG. 45 is a second cross-sectional view of the section line A-A in FIG. 41, and FIG. 46 is an enlarged view of A2 in FIG. 45. As shown in FIG. 45 and FIG. 46, in some embodiments, the travel switch 411 is installed in the main body 20, the main body 20 is provided with a first through hole 211 for the trigger portion 4111 to pass through towards the surface of the milk storage container 10, and the surface of the milk storage container 10 towards the main body 20 is provided with a first protrusion 16 matching the first through hole 211, and when the main body 20 is assembled with the milk storage container 10, the first protrusion 16 of the milk storage container 10 passes through the first through hole 211 to compress the trigger portion 4111. By providing the surface of the milk storage container 10 towards the main body 20 with the first protrusion 16 matching the first through hole 211, and the first protrusion 16 compresses the trigger portion 4111 through the first through hole 211, the trigger portion 4111 can be compressed, and the matching of the first through hole 211 and the first protrusion 16 can further detect whether the main body 20 is correctly assembled with the milk storage container 10, and can also facilitate the correct positioning of the assembly.

[0545] In some embodiments, the second detection device 42 and the third detection device 43 in FIG. 43 can also include the travel switch 411, and the travel switch 411 can also be the structure in FIG. 46.

[0546] In some embodiments, the trigger portion 4111 is compressed to a preset position, and the travel switch 411 is triggered.

[0547] Optionally, the preset position can be a position at which the trigger portion 4111 is compressed when the host 20 and the milk storage container 10 are completely and correctly assembled, and the correct assembly means that the host 20 and the milk storage container 10 are assembled in a fixed position and are fixed together by a certain connection manner, for example, the installation guide groove 213 is installed in the installation guide 15, so that the two assemblies are fixed together. By triggering the travel switch 411 when the trigger portion 4111 is compressed to the preset position, the travel switch 411 can be triggered only when it is detected that the host 20 and the milk storage container 10 are completely and correctly assembled, so that the accuracy of detection can be improved, and the problem of falling due to the fact that the host 20 and the milk storage container 10 are only partially and correctly assembled can be reduced.

[0548] Optionally, the travel switch 411 can be electrically connected to the control module by a wire.

[0549] Optionally, when the travel switch 411 is triggered to indicate that the host 20 and the milk storage container 10 are not correctly assembled, when the time at which the travel switch 411 is triggered exceeds a preset time, the control module 810 determines that the host 20 and the milk storage container 10 are not correctly assembled, and controls the breast pump 1 to stop running and / or send a prompt signal.

[0550] Optionally, the preset time can be 0.2s (seconds) to 3s, for example, the preset time can be 0.2s, 0.3s, 0.4s, 0.5s, 1s, 2s or 3s.

[0551] It can be understood that the detection device 40 can not be limited to including the travel switch 411.

[0552] Please refer to FIG. 47, which is a third cross-sectional view of the section line A-A in FIG. 41. As shown in FIG. 47, the detection device 40 in FIG. 47 includes a first detection device 41, a second detection device 42 and a third detection device 43 respectively.

[0553] In some embodiments, the first detection device 41 has a sensing portion 4121, when the milk storage container 10 is adapted to be connected to the host 20 in a fixed position, that is, the milk storage container 10 is correctly assembled on the host 20, the sensing portion 4121 is pressed, the first detection device 41 is triggered to generate an electrical signal, and the control module 810 determines that the milk storage container 10 and the host 20 are correctly assembled in response to receiving the electrical signal.

[0554] In some embodiments, the first detection device 41 is triggered when the host 20 and the milk storage container 10 are not correctly assembled.

[0555] As shown in FIG. 47, in some embodiments, the first detection device 41 includes a pressure sensor 412, the pressure sensor 412 includes a sensing portion 4121, and the pressure sensor 412 is triggered when the host 20 and the milk storage container 10 are correctly assembled or not correctly assembled.

[0556] Optionally, when the host 20 is correctly assembled with the milk storage container 10, the sensing portion 4121 is pressed, and the pressure sensor 412 is triggered, i.e. the pressure sensor 412 is powered on.

[0557] At this time, the sensing portion 4121 in the first detection device 41 is the sensing portion 4121 of the pressure sensor 412.

[0558] The pressure sensor 412 included in the first detection device 41 is described in detail below. It can be understood that such description is not limited to the first detection device 41, and other detection devices 40 can also be arranged in accordance with the embodiments of the first detection device 41.

[0559] Optionally, the sensing portion 4121 of the pressure sensor 412 can be a circular arc-shaped protrusion. In this way, when the sensing portion 4121 is pressed, the pressure sensor 412 is less likely to damage the fittings.

[0560] Optionally, the sensing portion 4121 of the pressure sensor 412 can be stretchable. In this way, when the host 20 is correctly assembled with the milk storage container 10, the sensing portion 4121 can be compressed when it is pressed. On the one hand, the stretchable sensing portion 4121 can improve the sensitivity of the pressure sensor 412 in detecting the pressure, and on the other hand, it can prevent the surface of the fittings from being damaged due to excessive pressure between the sensing portion 4121 and the triggering portion 4111, thereby further preventing the pressure sensor 412 from damaging the fittings.

[0561] As shown in FIG. 47, in some embodiments, the pressure sensor 412 is installed in the host 20, and the surface of the host 20 towards the milk storage container 10 is provided with a second through hole 214 for the sensing portion 4121 to pass through.

[0562] As shown in FIG. 47, optionally, the sensing portion 4121 extends out of the host 20 towards the surface of the milk storage container 10 through the second through hole 214. When the host 20 is assembled with the milk storage container 10, the milk storage container 10 approaches the host 20, and the surface of the milk storage container 10 presses or compresses the sensing portion 4121.

[0563] In the above manner, when the host 20 is assembled with the milk storage container 10, the pressure with which the sensing portion 4121 is pressed can be increased, and the accuracy of determining that the host 20 is correctly assembled with the milk storage container 10 can be improved.

[0564] In some embodiments, the sensing portion 4121 is pressed to a preset pressure position, and the pressure sensor 412 is triggered.

[0565] Optionally, the preset pressure position can be the position reached by the sensing portion 4121 when it is pressed when the host 20 is completely and correctly assembled with the milk storage container 10.

[0566] In some embodiments, the pressure sensor 412 is triggered when the pressure detected by the pressure sensor 412 reaches a preset pressure value.

[0567] Optionally, the preset pressure value can be the pressure that the pressure sensor 412 receives when the host 20 and the milk storage container 10 are completely and correctly assembled.

[0568] Optionally, the preset pressure value can be in the range of 1N (Newton) to 10N, for example, the preset value can be 1N, 2N, 3N, 4N, 5N, 6N, 7N, 8N, 9N or 10N, etc.

[0569] In this way, the pressure sensor 412 is triggered only when the host 20 and the milk storage container 10 are completely and correctly assembled, thereby improving the accuracy of detection and reducing the problem of falling due to partial correct assembly of the host 20 and the milk storage container 10.

[0570] Optionally, when the host 20 and the milk storage container 10 are not correctly assembled, the sensing portion 4121 is not pressed, and at this time the pressure sensor 412 is triggered, that is, the pressure sensor 412 is powered on. In this embodiment, when the host 20 and the milk storage container 10 are correctly assembled, the sensing portion 4121 is pressed, and the pressure sensor 412 is not powered on.

[0571] Optionally, when the pressure sensor 412 is triggered to indicate that the host 20 and the milk storage container 10 are not correctly assembled, when the time when the pressure sensor 412 is triggered exceeds a preset time, the control module 810 determines that the host 20 and the milk storage container 10 are not correctly assembled, and controls the breast pump 1 to stop running and / or issue a prompt signal.

[0572] It can be understood that the detection device 40 can not be limited to including the travel switch 411 or the pressure sensor 412.
