[0110] In the working process of the breast pump 10, the breast shield 14 is covered on the breast of the user to form a closed milk suction space between the breast shield 14 and the breast of the user. The negative pressure mechanism in the breast pump 10 forms negative pressure in the milk suction space between the breast shield 14 and the breast of the user through the joint action of the air pipe assembly 20 and other accessories, so that the breast pump 10 can suck out the milk in the breast of the user and load the milk through the milk storage container 12.

[0111] Optionally, the air pipe assembly 20 is used to connect one or two or more milk storage containers to the host, and in FIG. 1, the air pipe assembly 20 is used to connect two milk storage containers to the host.

[0112] Further, when the air pipe assembly 20 is used to connect one milk storage container to the host, the air pipe assembly at least includes a pipe joint, a first pipe and a second pipe, the first pipe is connected to the host and the pipe joint, the second pipe is connected to the milk storage container and the pipe joint, and the host provides negative pressure to the milk storage container through the first pipe, the pipe joint and the second pipe.

[0113] Further, when the air pipe assembly 20 is used to connect two milk storage containers to the host, the structure can be the first connector or the second connector in the following embodiments, and specific details can be referred to the description of the first connector or the second connector, which will not be repeated here.

[0114] Please refer to FIGS. 2-3, in some embodiments of the present application, a milk storage container 12 is provided, which includes a breast shield 14 and a shell 13. The breast shield 14 is used to fit the breast. The shell 13 is connected to the breast shield 14. At least one of the breast shield 14 and the shell 13 is provided with a support 15, which supports the stable placement of the milk storage container 12.

[0115] In some embodiments of the present application, when the shell 13 and the breast shield 14 are assembled together, a space for containing milk is formed between the shell 13 and the breast shield 14, the shell 13 and the breast shield 14 are sealingly connected, and the shell 13 and the breast shield 14 are detachably connected.

[0116] In some embodiments of the present application, the shell 13 can also be provided with an independent space for containing milk, i.e. the shell 13 can independently load milk.

[0117] By detachably assembling the shell 13 and the breast shield 14, the shell 13 and the breast shield 14 can be combined in the breast pump 10, so that the structure of the breast pump 10 is more compact, and the combination between the components of the breast pump 10 is more firm. In the process of cleaning the accessories in the breast pump 10, the shell 13 and the breast shield 14 can be separated, and then the shell 13 and the breast shield 14 can be cleaned respectively, so as to improve the cleaning effect.

[0118] By arranging the support 15 on at least one of the breast shield 14 and the shell 13, and further supporting the milk storage container 12 by the support 15, the milk storage container 12 can be stably placed, the risk of the milk storage container 12 being overturned and the milk overflowing from the milk storage container 12 is reduced, and the user does not need to hold or support the milk storage container 12 all the time, so that the use of the breast pump 10 is more convenient, and the user experience is improved.

[0119] In some embodiments of the present application, the support 15 is arranged on the shell 13.

[0120] Further, the support 15 is arranged on the bottom of the shell 13.

[0121] When the shell 13 is placed alone, the shell 13 can be stably placed by being supported by the support 15, and the risk of the shell 13 being overturned is reduced.

[0122] Since the volume and weight of the shell 13 are greater than the volume and weight of the breast shield 14, when the shell 13 is combined with the breast shield 14, the center of gravity of the milk storage container 12 is located in the shell 13. Arranging the support 15 on the shell 13 can make the milk storage container 12 be stably placed.

[0123] In some embodiments of the present application, the support 15 is arranged on the breast shield 14.

[0124] Further, the support 15 is arranged on the bottom of the breast shield 14.

[0125] After the breast shield 14 and the shell 13 are assembled together, the support 15 arranged on the breast shield 14 and the bottom structure of the shell 13 form a stable support structure, and further the milk storage container 12 can be stably placed.

[0126] In some embodiments of the present application, the support 15 is arranged on the breast shield 14.

[0127] By forming a stable support structure for the milk storage container 12 in a three-point support manner, the milk storage container 12 can be stably placed. In the process of disassembling the shell 13 and the breast shield 14, the support 15 can be used as a force structure, so that the user can more conveniently and quickly disassemble the shell 13 and the breast shield 14.

[0128] In some embodiments of the present application, the support 15 is provided on the breast shield 14, and after the breast shield 14 and the shell 13 are assembled together, the support 15 is located on the side of the breast shield 14 which is on the same side as the bottom of the shell 13, and the support 15 extends from one side of the breast shield 14 to the other side of the breast shield 14.

[0129] By extending the support 15 from one side of the breast shield 14 to the other side of the breast shield 14, the support 15 is in the shape of a strip. In the breast shield 14, by arranging the support 15 on the same side as the bottom of the shell 13, the support 15 in the shape of a strip and the bottom of the shell 13 together form a support structure for supporting the milk storage container 12, so that the milk storage container 12 can be stably placed.

[0130] In some embodiments of the present application, the support 15 in the shape of a strip is provided with at least one notch.

[0131] In some embodiments of the present application, the breast shield 14 and the shell 13 are both provided with the support 15.

[0132] By providing the support 15 in the breast shield 14 and the shell 13, a stable support structure for the milk storage container 12 is formed by the support 15, so that the milk storage container 12 can be stably placed. In the process of disassembling the breast shield 14 and the shell 13, the support 15 provided on the shell 13 and the support 15 provided on the breast shield 14 can be used as a force structure, so that the breast shield 14 and the shell 13 can be easily disassembled.

[0133] In some embodiments of the present application, after the milk storage container 12 is placed on the placement table, the contact mode between the support 15 and the placement table includes at least one of point contact, line contact or surface contact.

[0134] When the contact mode between the support 15 and the placement table is point contact, the number of contact points between the support 15 and the placement table is at least three, and the contact points are arranged dispersedly, so that the support 15 forms a stable support for the milk storage container 12. If the contact surface between the support 15 and the placement table is small, it is also regarded as point contact.

[0135] After the milk storage container 12 is loaded with milk, the projection of the center of gravity of the whole formed by the milk storage container 12 and the milk is located within the area range enclosed by the adjacent support points, so as to avoid the situation that the supporting force of the support 15 on the milk storage container 12 deviates, and thus the stability and reliability of the support 15 on the milk storage container 12 are ensured.

[0136] When the contact mode between the support 15 and the placement table is line contact, the number of contact lines between the support 15 and the placement table is at least two, and at least two of the contact lines are not collinear, so that the support 15 forms a stable support for the milk storage container 12.

[0137] When the milk storage container 12 is loaded with milk, the projection of the center of gravity of the whole formed by the milk storage container 12 and the milk is located within the area enclosed by the adjacent support lines, so as to avoid the deviation of the supporting force of the support 15 on the milk storage container 12, and thus ensure the stability and reliability of the support of the support 15 on the milk storage container 12.

[0138] When the contact between the support 15 and the placement table is in the form of line contact, the contact lines can intersect each other or be connected to each other. The contact lines can be straight lines or curves. When the contact lines are curves, the number of the contact lines is at least one.

[0139] When the contact between the support 15 and the placement table is in the form of the combination of line contact and point contact, the contact points are not located on the contact lines, so as to form stable support of the support 15 on the milk storage container 12.

[0140] When the contact between the support 15 and the placement table is in the form of surface contact, when the milk storage container 12 is loaded with milk, the projection of the center of gravity of the whole formed by the milk storage container 12 and the milk is located within the range of the contact surface, so as to avoid the deviation of the supporting force of the support 15 on the milk storage container 12, and thus ensure the stability and reliability of the support of the support 15 on the milk storage container 12.

[0141] Please refer to FIGS. 2-3. In some embodiments of the present application, the bottom of the shell 13 is provided with a first support 16.

[0142] The first support 16 supports the shell 13, so that the milk storage container 12 can be placed stably. The first support 16 is arranged at the bottom of the shell 13, so that the milk storage container 12 is placed with the milk inlet upward, thereby reducing the risk of milk overflow.

[0143] In some embodiments of the present application, the bottom of the shell 13 is outwardly convex to form the first support 16.

[0144] During the operation of the breast pump 10, the milk level in the milk storage container 12 rises from the bottom of the shell 13 until the milk storage container 12 is filled. The milk inlet of the shell 13 is arranged away from the bottom of the shell 13. The bottom of the shell 13 is outwardly convex to form the first support 16, so that the first support 16 can contact the placement table when the shell 13 is placed on the placement table, and thus the first support 16 can support the shell 13. When the first support 16 supports the shell 13, the shape of the force application part of the first support 16 can be at least one of arc, curve, broken line, straight line or scattered dots, so that the first support 16 can form stable support on the shell 13.

[0145] In some embodiments of the present application, the first support 16 is one or more of a support bar, a support leg, and a support column formed on the bottom of the shell 13.

[0146] The shell 13 is supported by at least one of the support bar, the support leg, or the support column, so that the shell 13 can be stably placed.

[0147] When the first support 16 is the support bar, the number of the support bars is at least two, and the shell 13 is supported by the at least two support bars, so that the shell 13 can be stably placed.

[0148] When the first support 16 is the support leg, the number of the support legs is at least three, and the support legs are dispersedly arranged on the bottom of the shell 13, so that the shell 13 can be stably placed.

[0149] When the first support 16 is the support column, an end surface of the support column forms a support surface when the shell 13 is placed, so that the shell 13 is supported by the support column, and the shell 13 can be stably placed.

[0150] In some embodiments of the present application, the breast shield 14 is provided with a second support 17 at the bottom thereof.

[0151] The second support 17 is arranged at the bottom of the breast shield 14, so that the second support 17 independently or together with the bottom of the shell 13 forms a stable support for the storage device 12, and the milk inlet of the storage container 12 faces upward, thereby reducing the risk of milk overflow.

[0152] Referring to FIGS. 2 and 3, in some embodiments of the present application, the second support 17 is formed on the bottom of the breast shield 14.

[0153] In some embodiments of the present application, the second support 17 is one or more of a support bar, a support leg, and a support column formed on the bottom of the breast shield 14.

[0154] The bottom of the breast shield 14, i.e., the part of the breast shield 14 facing the bottom of the shell 13, is provided with the second support 17 formed on the bottom of the breast shield 14, so that the second support 17 and the bottom of the shell 13 together form a support structure for stably supporting the storage container 12, and the storage container 12 can be stably placed. When it is necessary to separate the breast shield 14 from the shell 13, the second support 17 can also be used as a force structure to separate the breast shield 14 from the shell 13.

[0155] In some embodiments of the present application, the first support 16 is arranged on the bottom of the shell 13, and a contact surface of the first support 16 contacting the placement surface is at least partially arc-shaped.

[0156] By making the contact surface of the first support 16 with the placement surface arc-shaped, and further expanding the contact range of the first support 16 with the placement surface, the shell 13 can be placed independently, and the stability of the breast milk storage container 12 after being placed is improved.

[0157] In some embodiments of the present application, the breast milk collecting cover 14 is provided with a second support 17 at the bottom, and the second support 17 includes at least two support points in contact with the placement surface.

[0158] By forming at least two support points on the second support 17, and further forming a three-point support structure with the first support 16 or the bottom of the shell 13, the stability of the breast milk storage container 12 after being placed is ensured, and the risk of the breast milk storage container 12 being knocked over is reduced.

As shown in FIG. 5, the milk storage container 100 includes a shell 110 and a cover 120, and the shell 110 is provided with a milk outlet 150.

[0173] Optionally, the milk storage container 100 includes a milk cover, a milk bowl, a milk bottle, etc., which are not limited in the present application.

[0174] Optionally, the shape of the milk outlet 150 is not limited to the circular shape in FIG. 5, but can also be other shapes such as a square shape, a triangular shape, etc., and the shape of the milk outlet 150 is not limited in the present application.

[0175] Please refer to FIG. 6 and FIG. 7 again, FIG. 6 is a perspective view of the milk storage container according to an embodiment of the present application, and FIG. 7 is a schematic view of the milk storage container according to an embodiment of the present application. As shown in FIG. 6 and FIG. 7, the milk storage container 100 comprises a nipple plug 140, which is adapted to be plugged into the milk outlet 150.

[0176] In some embodiments, the nipple plug 140 is elastic and / or made of soft gel material.

[0177] Specifically, soft gel is a soft material made of polymer material, which can be bent, stretched and compressed.

[0178] As shown in FIG. 6, the milk storage container 100 comprises a housing 110, a cover 120 and a breast shield 130.

[0179] In some embodiments, the cover 120 does not have the function of generating negative pressure, and the cover 120 is used to connect to the host to receive the negative pressure transmitted by the host.

[0180] For example, the air pipe connection interface on the cover 120 is connected to a first air pipe, the first air pipe is connected to a first port of an air pipe assembly, a second port of the air pipe assembly is connected to a second air pipe, the second air pipe is connected to the host, the host transmits negative pressure to the cover 120 through the second air pipe, the air pipe assembly, the first air pipe and the air pipe connection interface on the cover 120, and the cover 120 transmits the negative pressure to the breast shield 130 in the milk storage container 100.

[0182] In some embodiments, the breast shield 130 is used to fit the breast of the wearer of the milk storage container 100 and to suck out breast milk under the action of negative pressure.

[0183] In some embodiments, the housing 110 and the breast shield 130 together form a milk storage space for storing breast milk.

[0184] In some embodiments, the housing 110 alone forms the milk storage space.

[0185] Alternatively, the inside of the milk storage container 100 described in the specification corresponds to the milk storage space.

[0186] Please refer to FIG. 8 and FIG. 9 again, FIG. 8 is a sectional view of A-A in FIG. 7, and FIG. 9 is an enlarged view of B in FIG. 8. As shown in FIG. 8 and FIG. 9, there is an exhaust passage 141 between the nipple plug 140 and the milk outlet 150, and the exhaust passage 141 can communicate the inside of the milk storage container with the atmosphere.

[0187] Specifically, the air path for the inside of the milk storage container to communicate with the atmosphere is shown by the dashed line in FIG. 9. When the breast pump is pumping milk, the milk will enter the inside of the milk storage container, and the gas in the inside of the milk storage container will enter the atmosphere through the air path shown by the dashed line in FIG. 9 along with the milk, so as to balance the air pressure in the inside of the milk storage container and prevent the air pressure in the inside of the milk storage container from being too large, so that the pumped milk cannot flow into the milk storage container.

[0188] In the present application, the exhaust is performed through the exhaust passage 141, and the milk outlet 150 does not need to be in a fully open state, so as to reduce the probability of pollutants entering the inside of the milk storage container.

[0189] In some embodiments, as shown in FIGS. 8 and 9, the exhaust passage 141 is arranged in the nipple plug 140.

[0190] The exhaust passage 141 arranged in the nipple plug 140 can facilitate cleaning of the exhaust passage 141.

[0191] In some embodiments, the exhaust passage 141 is an exhaust groove or an exhaust hole arranged on the nipple plug 140.

[0192] Please refer to FIG. 10 again, which is a schematic view of a nipple plug provided in an embodiment of the present application. As shown in FIGS. 9 and 10, the exhaust passage 141 in FIGS. 9 and 10 is an exhaust groove arranged on the nipple plug 140.

[0193] Further, the exhaust groove penetrates the lower surface 143 of the nipple plug 140 close to the inside of the milk storage container.

[0194] Alternatively, the exhaust groove can also not penetrate the lower surface 143, but be between the upper surface 142 of the nipple plug 140 away from the inside of the milk storage container and the lower surface 143 close to the inside of the milk storage container.

[0195] In some embodiments, the nipple plug 140 further includes an upper surface 142 away from the inside of the milk storage container, the upper surface 142 is provided with a first limiting portion 1421, and the lower surface 143 is provided with a second limiting portion 1431; the first limiting portion 1421 and the second limiting portion 1431 are used to fix the nipple plug 140 to the milk outlet 150.

[0196] The first limiting portion 1421 and the second limiting portion 1431 can prevent the nipple plug 140 from loosening or falling into the inside of the milk storage container.

[0197] Please refer to FIG. 11 again, which is an enlarged schematic view of C in FIG. 6. As shown in FIGS. 6, 9 and 11, the milk storage container 100 includes an outlet wall 151 surrounding the milk outlet outlet, and the outlet wall 151 extends away from the inside of the milk storage container.

[0198] Optionally, the outlet wall 151 extends away from the interior of the milk storage container and protrudes from the surface of the housing 110.

[0199] Further, the outlet wall 151 is provided with an air vent gap 152, and an air vent groove is provided to communicate the interior of the milk storage container and the air vent gap 152, so as to communicate the interior of the milk storage container with the atmosphere.

[0200] Optionally, the shape of the air vent gap 152 is not limited in the present application.

[0201] The outlet wall 151 can play a role of guiding the milk flowing out of the milk outlet 150, so as to prevent the milk from flowing onto the housing 110, and the outlet wall 151 can better block the contaminants from entering the air vent groove.

[0202] In some embodiments, the air vent passage is provided in the housing.

[0203] In some embodiments, the milk outlet 150 is in communication with the air vent passage.

[0204] Illustratively, the milk outlet 150 includes a plug-in opening, an air vent passage connected to the plug-in opening, and a milk outlet plug for plugging the plug-in opening, and the air vent passage communicates the milk storage container with the atmosphere.

[0205] Illustratively, the milk outlet 150 includes a larger plug-in opening and a smaller air vent opening, and the milk outlet plug 140 is used for plugging the plug-in opening, and the smaller air vent opening serves as the air vent passage.

[0206] Illustratively, the milk outlet wall forming the plug-in opening is provided with an air vent groove, the air vent groove communicates the upper surface and the lower surface of the milk outlet wall, and the milk outlet plug 140 cannot plug the air vent groove after plugging the plug-in opening, and the air vent groove serves as the air vent passage.

[0207] Please refer to FIG. 6 and FIG. 9 to FIG. 11, in some embodiments, the milk outlet plug 140 includes a shielding member 1422, and the shielding member 1422 can shield the air vent passage 141.

[0208] The shielding member 1422 can further reduce the probability of contaminants entering the interior of the milk storage container.

[0209] In some embodiments, the shielding member 1422 is formed by extending outwardly from the upper surface 142 of the milk outlet plug 140.

[0210] The shape of the shielding member 1422 formed by extending outwardly is not limited in the present application, and it can only shield the air vent passage 141.

[0211] In some embodiments, referring to FIGS. 6-10, the milk storage container 100 further comprises a breast shield 130 connected with the shell 110 to form a space for storing milk, and a nipple 140 connected with the breast shield 130.

[0212] In some embodiments, the nipple 140 is integrally formed with the breast shield 130.

[0213] In the above-mentioned manner, the nipple 140 is integrally formed with the breast shield 130, which prevents the nipple 140 from being lost.

[0214] In some embodiments, the shielding member 1422 extends outwardly from the upper surface 142 of the nipple 140 to connect with the breast shield 130.

[0215] In some embodiments, the air vent 141 is arranged near the side of the milk outlet 150 close to the breast shield 130.

[0216] Therefore, when the nipple 140 is connected with the breast shield 130, the connecting member connecting the nipple 140 and the breast shield 130 can naturally shield the air vent 141, and the shielding member 1422 has both the connecting function and the shielding function, which is ingenious.

[0217] In some embodiments, the nipple 140 is not limited to be connected with the breast shield 130, for example, the nipple 140 can also be connected with the cover 120, and in this case, the shielding member extends outwardly from the upper surface 142 of the nipple 140 to connect with the cover 120.

[0218] When the nipple 140 is connected with the cover 120, the air vent can be arranged near the side of the milk outlet 150 close to the cover 120, so that the connecting part of the nipple 140 and the cover 120 can serve as the blocking member of the air vent.

[0219] Optionally, the nipple 140 can also be connected with the milk storage container 100, which is not limited in the present application.

[0220] The embodiments of the present application also provide a breast pump, which comprises a host and the milk storage container in any of the above-mentioned embodiments.

[0221] The host is configured to apply negative pressure to the breast shield in the milk storage container to let the breast shield suck out breast milk, and the breast milk flows into the milk storage container.

[0222] Optionally, the host comprises a negative pressure mechanism configured to directly or indirectly apply negative pressure to the breast shield to suck the breast milk into the milk storage container.

[0223] Optionally, the negative pressure mechanism includes, but is not limited to, a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, and the like.

[0224] Optionally, the negative pressure mechanism can be directly connected to the breast shield to cause negative pressure in the breast shield, or can indirectly cause negative pressure in the breast shield by transmitting negative pressure to a diaphragm or a liquid barrier such as an air bag.

[0225] Optionally, the main machine is arranged in the cover of the milk storage container.

[0226] Optionally, the main machine is connected to the cover of the milk storage container, and the cover is used to transmit negative pressure generated by the main machine.

[0227] In summary, the application provides a milk storage container and a breast pump. The milk storage container includes a shell and a nipple plug. The shell is provided with a milk outlet, and the nipple plug is adapted to be plugged into the milk outlet. After the nipple plug is plugged into the milk outlet, an exhaust passage is formed between the nipple plug and the milk outlet. The exhaust passage can connect the inside of the milk storage container with the atmosphere. By arranging the exhaust passage between the nipple plug and the milk outlet, the milk outlet is no longer completely open, effectively reducing the probability of pollutants entering the inside of the milk storage container.

[0228] Please refer to FIG. 12, FIG. 13 and FIG. 15. FIG. 12 is a schematic view of a milk storage container according to an embodiment of the application. FIG. 13 is a sectional view of A-A in FIG. 12. FIG. 15 is a sectional view of a milk storage container without a cover according to an embodiment of the application. As shown in FIG. 12 and FIG. 13, the milk storage container 200 includes a milk storage container body 212 and a cover 220, and the cover 220 is arranged on the milk storage container body 212.

[0229] As shown in FIG. 13, the milk storage container 200 further includes an elastic diaphragm 211, and the elastic diaphragm 211 is integrally formed with the milk storage container body 212.

[0230] Optionally, the milk storage container body 212 is made of hard rubber, and the elastic diaphragm 211 is made of soft rubber. Both the hard rubber and the soft rubber are made of polymer materials. The hard rubber is a hard material that is not easy to deform, and the soft rubber is a soft material that can be bent, stretched and compressed.

[0231] The milk storage container body 212 and the elastic diaphragm 211 are integrally formed, so that the user does not need to manually install the elastic diaphragm 211 in the milk storage container body 212, and thus no assembly gap is generated, thereby ensuring the sealing performance of the milk storage container 200 during breast pumping.

[0232] In some embodiments, the milk storage container body 212 is provided with an opening 2121, and the cover 220 is arranged on the opening 2121 and is sealingly connected to the elastic diaphragm 211.

[0233] Please refer to FIG. 13, the milk storage container 200 further comprises a breast shield 230, which forms a space for storing milk, i.e. a milk storage space 240, together with the milk storage container body 212, and the elastic diaphragm 211 is used to transmit negative pressure to the side of the breast shield 230 that contacts the breast.

[0234] When the cover 220 is connected to the host, the host can indirectly apply negative pressure to the breast shield 230 through the elastic diaphragm 211 to make the breast shield 230 suck out breast milk, which will flow into the milk storage space 240 formed by the breast shield 230 and the milk storage container body 212.

[0235] Please refer to FIG. 13 and FIG. 14, which is an enlarged view of B in FIG. 13, as shown in FIG. 13 and FIG. 14, the milk storage container 200 comprises an elastic seal 2111, which seals the connection between the elastic diaphragm 211 and the cover 220 when the cover 220 is installed on the milk storage container body 212, and forms a sealed space between the elastic diaphragm 211 and the cover 220.

[0236] Specifically, the sealed space is formed by the elastic diaphragm 211, the cover 220 and the milk storage container body 212 together, and the host can apply negative pressure to the breast shield 230 through the elastic diaphragm 211 by sucking the gas in the sealed space, so that the breast shield 230 sucks out breast milk.

[0237] In some embodiments, the cover 220 comprises a gas pipe connecting port for connecting a gas pipe, so that the cover 220 can connect one end of the gas pipe through the gas pipe connecting port, and the other end of the gas pipe can be directly or indirectly connected to the host.

[0238] Please refer to FIG. 15 and FIG. 16, which is an enlarged view of C in FIG. 15.

[0239] As shown in FIG. 13 to FIG. 16, in some embodiments, when the cover 220 is installed on the milk storage container body 212, the cover 220 presses the elastic seal 2111 in the assembly direction, and the elastic seal 2111 seals the connection between the elastic diaphragm 211 and the cover 220.

[0240] In some embodiments, the elastic seal 2111 is annular.

[0241] In the related art, a sealing line is generally provided on the cross section of the assembly direction of the cover 220, and the cover 220 forms a seal by pressing the sealing line from the side, but this way will cause the cover 220 to rub against the soft rubber sealing line on the side when the cover 220 is installed / dismounted, and a relatively large friction force needs to be overcome, which is poor in operability and experience.

[0242] Therefore, in the above embodiment, the cover 220 is pressed against the elastic seal 2111 in the assembly direction, and almost no friction is generated between the cover 220 and the elastic seal 2111 during installation and removal, so that the installation difficulty of the cover 220 can be reduced.

[0243] In addition, the elastic seal 2111 has a large elastic deformation, and can play a good sealing effect when the assembly gap is large, the part error is large, the part deformation occurs, and the like, and the reliability of the seal is improved.

[0244] In some embodiments, the elastic seal 2111 includes an inner side and an outer side, the outer side contacts the cover 220, and the inner side is connected to the elastic diaphragm 211 or the milk storage container body 212.

[0245] Optionally, the inside of the milk storage container can be understood as a milk storage space 240.

[0246] Referring to FIGS. 13 to 16, in some embodiments, the milk storage container body 212 includes a diaphragm shell 2122, and the elastic diaphragm 211 is integrally formed on the diaphragm shell 2122.

[0247] In some embodiments, the diaphragm shell 2122 extends from the milk storage container body 212 to the inside of the milk storage container.

[0248] In some embodiments, the cover 220 includes a seal 221, the seal 221 is connected to the inner side of the cover 220, and the seal 221 is sealingly connected to the elastic diaphragm 211 or the diaphragm shell 2122.

[0249] In some embodiments, the seal 221 is attached to the diaphragm shell 2122, and the bottom of the seal 221 presses the elastic seal 2111.

[0250] In some embodiments, the diaphragm shell 2122 includes at least one mounting groove 21221, and the cover 220 includes at least one elastic member 2212 corresponding to the mounting groove 21221, so as to fixedly connect the cover 220 and the milk storage container body 212.

[0251] In the present application, the cover 220 and the milk storage container body 212 are fixed by the elastic member 2212, compared with the related art in which a sealing line is arranged on the cross section in the assembly direction of the cover 220, and the cover 220 is pressed against the sealing line by the side surface to form a seal, so that the friction generated during installation and removal is small, and the installation and removal is more labor-saving.

[0252] Please refer to Fig. 17, which is a structural schematic diagram of the elastic member according to an embodiment of the present application. As shown in Fig. 14 and Fig. 17, the elastic member 2212 includes a first elastic part 22121 and a second elastic part 22122, and the first elastic part 22121 has an arc surface.

[0253] Optionally, the arc surface in the first elastic part 22121 is in contact with the diaphragm shell 2122 and rubs against the diaphragm shell 2122 when the cover 220 is installed.

[0254] By arranging the arc surface on the first elastic part 22121, the frictional force generated when the cover 220 is installed or removed can be further reduced, and the arc surface can make the elastic member 2212 more easily exit from the installation slot 21221 after the elastic member 2212 enters the installation slot 21221.

[0255] Please refer to Fig. 13 to Fig. 16. In some embodiments, the sealing member 221 is provided with a placement slot 2211, and the elastic member 2212 is arranged in the placement slot 2211.

[0256] In some embodiments, when the elastic member 2212 is arranged in the placement slot 2211, the first elastic part 22121 of the elastic member 2212 is away from the bottom of the placement slot 2211, and the second elastic part 22122 of the elastic member 2212 is close to the bottom of the placement slot 2211.

[0257] In some embodiments, the elastic member 2212 is detachably arranged in the placement slot 2211, and the elastic member 2212 can abut against the bottom of the installation slot 21221 and the bottom of the placement slot 2211.

[0258] In some embodiments, the elastic member 2212 is fixed to the bottom of the placement slot 2211.

[0259] Specifically, during the installation of the cover 220, the elastic member 2212 in the sealing member 221 is pressed in the placement slot 2211, and when the cover 220 reaches a preset installation position, the first elastic part 22121 in the elastic member 2212 enters the installation slot 21221 from the placement slot 2211, thereby fixing the cover 220 and the main body 212 of the milk storage container.

[0260] In some embodiments, the installation slot 21221 is arranged opposite to the placement slot 2211, thereby reducing the difficulty of the elastic member 2212 entering the installation slot 21221.
