Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, and in particular to a breast pump for collecting breast milk. Background Art

[0002] The prior art breast pump includes a cavity and a cup body installed at the bottom of the cavity, and a trumpet-shaped cup head is arranged on the front of the cavity and connected with the cavity. When in use, the cup head of the breast pump is placed on the breast to collect the milk into the cup body, and the whole breast pump is supported by the bra, so as to achieve the purpose of convenient use.

[0003] However, in the breast pump of the related art, the cup head design includes a cup cover, a channel extending from the bottom of the cup cover, an air groove located above the channel and connected to the channel, and an elastic suction disk located in the air groove. The channel is divided into an upper suction channel and a lower lotion channel. The suction channel is connected to the air groove, and the elastic suction disk is deformed to form a negative pressure in the air groove, so that the negative pressure is transmitted to the cup cover through the suction channel, squeezing the breast to make the lotion flow out and flow to the cup body through the lotion channel. Although this structure has a better breast pumping effect, the suction channel and the lotion channel are in the same channel. When sucking, the negative pressure will also cause the suction channel to suck a small amount of milk into the air groove, making it inconvenient to clean. Moreover, the cavity and the cup body are split structures with complex structures. Multiple structural components cannot avoid the exposure of mold marks, and the appearance is not aesthetically pleasing.

[0004] Therefore, it is necessary to provide a new breast pump to solve the above problems. Utility Model Content

[0028] The specific implementation of the present utility model is described in detail below with reference to the accompanying drawings.

[0029] The specific implementation modes / examples described herein are specific implementation modes of the present utility model, which are used to illustrate the concept of the present utility model, are explanatory and exemplary, and should not be interpreted as limiting the implementation modes of the present utility model and the scope of the present utility model. In addition to the examples described herein, those skilled in the art can also adopt other obvious technical solutions based on the contents disclosed in the claims and the specification of this application, and these technical solutions include any obvious replacement and modification of the embodiments described herein, which are within the protection scope of the present utility model.

[0030] The following descriptions of the embodiments refer to the attached drawings to illustrate specific embodiments of the present invention. Directional terms mentioned in the present invention, such as up, down, front, back, left, right, inside, outside, side, etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention.

[0031] Please refer to Figure 1-6 As shown, the utility model provides a breast pump 100, comprising a breast collecting cup 1, a shell assembly 2, a stabilizing plate 3, and an elastic air bag 4.

[0032] The breast milk collecting cup 1 comprises a breast milk collecting cup body 11 for collecting breast milk and a bra 12 fixed to the front side of the breast milk collecting cup body 11 .

[0033] In this embodiment, the so-called front side refers to the side of the breast pump 100 facing the breast when the user is using it.

[0034] The bra 12 includes a breast tube 121 fixed to the open end of the breast collecting cup body 11 and extending horizontally, and a breast cup 122 extending from the outer end of the breast tube 121 to the outside of the breast collecting cup body 11 and having a trumpet shape.

[0035] In this embodiment, the breast collecting cup 1 is made of an elastic material, such as silicone. The breast collecting cup body 11 and the bra 12 can be an integral structure or a split structure. When it is a split structure, the breast tube 121 of the bra 12 is designed to be directly plugged or rotatably installed on the open end of the breast collecting cup body 11. In this embodiment, the breast collecting cup 1 is preferably an integral injection molding structure, which not only effectively reduces the number of main components and simplifies the structure, but also makes cleaning more convenient.

[0036] The breast cup 122 is trumpet-shaped, which is adapted to the breast. In addition, the material is elastic, so it can better match and fit the breast, improving comfort. When the breast cup 122 is placed on the breast, the nipple is directly opposite to the milk duct 121. When negative pressure is generated in the milk duct 121, the milk in the breast is sucked out and flows into the breast cup body 11 through the milk duct 121 for collection. Because the breast cup 122 is made of elastic material, it can adaptively fit the breast when the breast is adjusted to the corresponding position, playing a certain dynamic adjustment role without causing milk leakage, and has better reliability.

[0037] like Figure 5-6 The shell assembly 2 is made of a hard material, and includes a shell 21 that covers the open end of the breast cup body 11 and forms a detachable connection, and an air nozzle 22 and an air pump assembly 23 that are arranged through the shell 21. The air pump assembly 23 is connected to the air nozzle 22 through an air pipe.

[0038] The air pump assembly 23 may be provided as a separate structure located outside the housing 21, such as Figure 1-4 It can also be arranged inside the housing 21 and integrated into the breast pump 100 to form an integrated structure, such as Figure 5-6 As shown, this is the difference between the two embodiments of the present invention, and both are feasible.

[0039] In this embodiment, the air pump assembly 23 is integrated into the breast pump 100. Figure 5-6 Specifically, the air pump assembly 23 includes an air pump 231 and an air-closing switch valve 232 respectively installed in the housing 21, and the air nozzle 22 includes an air outlet nozzle 221 and an air inlet nozzle 222 respectively connected to the elastic air bag 4. The air pump 231 is connected to the air outlet nozzle 221 through an air pipe, and is used to extract the air in the elastic air bag 4 to achieve milk suction. The air-closing switch valve 232 is connected to the air inlet nozzle 222 through an air pipe, and is used to introduce external air into the elastic air bag 4 when the air pump 231 stops working, so that the elastic air bag 4 recovers its elastic deformation. That is, when the air pump 231 inhales, the air-closing switch valve 232 is closed, and when the air pump 231 stops inhaling, the air-closing switch valve 232 is opened.

[0040] Continue to participate Figure 1-4As shown, the stabilizing plate 3 includes a plate body 31 which covers the open end of the milk collecting cup body 11 and whose periphery forms a detachable connection with the milk collecting cup body 11, a milk inlet 32 ​​which passes through the plate body 31 and is connected to the milk collecting cup body 11, a one-way valve 33 which covers the milk inlet 32, an air groove cup 34 which extends upward from the plate body 31 and is arranged around the milk inlet 32, and a connecting pipe 35 which passes through the front side of the air groove cup 34 and extends along an axial direction perpendicular to the air groove cup 34 to the open end of the milk collecting cup body 11.

[0041] In this embodiment, the stabilizing plate 3 is made of a hard material.

[0042] The plate body 31 is engaged with the open end of the milk collecting cup body 11 through the snap-fit ​​structure to form a closed space in the milk collecting cup body 11 to prevent the collected milk from overflowing.

[0043] More preferably, the edge of the plate 31 is close to the side of the milk collecting cup 11 and is recessed away from the milk collecting cup 11 to form a milk pouring groove (not shown in the figure). When the plate 31 is covered on the milk collecting cup 11, it and the milk pouring groove together form a milk pouring port 311, which is convenient for pouring milk from the milk collecting cup 11 after sucking. At the same time, this structure is an upper and lower installation structure, and the mold mark or installation mark of the milk pouring port 311 can be hidden, which is more beautiful.

[0044] The milk tube 121 and the connecting tube 35 form a detachable sealed connection, so that the milk tube 121 and the connecting tube 35 together form a channel structure for collecting milk.

[0045] The sealing connection between the milk tube 121 and the connecting tube 35 can be a plug-in connection or a rotation connection.

[0046] Specifically, in this embodiment, the outer circumference of the milk tube 121 is provided with an external thread, and the inner circumference of the connecting tube 35 is provided with an internal thread, and the external thread and the internal thread are screwed together to form a seal. This structural design is convenient for disassembly and assembly, and has good sealing performance. The design of the insertion of the milk tube 121 makes the channel structure for collecting the milk high in the front and low in the back. The inner diameter of the milk tube 121 is smaller than the inner diameter of the connecting tube 35, thereby forming a barrier function of the step structure, better preventing the milk from flowing back to the milk cup 122, and having better reliability. This is a rotary connection method.

[0047] Alternatively, the outer periphery of the milk tube 121 protrudes near one end of the connecting tube 35 to form a ring-shaped pattern, and the milk tube 121 is inserted into the connecting tube 35 and interference fits to form a sealed connection, which is plug-in connection.

[0048] The elastic airbag 4 is inserted into the air groove cup 34 and completely fits and covers the end of the connecting tube 35 close to the elastic airbag 4. The elastic airbag 4 is spaced from the milk inlet 32 ​​and its open end is detachably sealed with the open end of the air groove cup 34.

[0049] Preferably, the housing 21 is pressed against the open end of the elastic airbag 4 and forms a seal, further enhancing the sealing reliability. The air nozzle 22 is connected to the elastic airbag 4. The air pump assembly extracts the air in the elastic airbag 4 through the air nozzle 22, and the elastic airbag 4 is compressed and deformed, so that negative pressure is formed in the air groove cup 34, and the negative pressure is sequentially squeezed through the connecting tube 35, the milk duct 121 and the breast cup 122 to squeeze out the milk, and the milk flows to the air groove cup 34 through the milk duct 121 and the connecting tube 35, and then flows to the breast collecting cup body 11 through the milk inlet 32 ​​at the bottom of the air groove cup 34. When the air pump assembly inhales air to generate negative pressure in the air tank cup 34, the one-way valve 33 is in a closed state, and the milk flows to the bottom of the air tank cup 34. When the air pump assembly stops inhaling air, the elastic airbag 4 recovers its deformation and fits the connecting tube 35 to form a barrier, so that the milk does not flow back into the connecting tube 35, thereby avoiding milk leakage during movement. At the same time, the one-way valve 33 loses its suction force due to the disappearance of negative pressure, and the liquid milk presses the one-way valve 33 open by its own gravity and flows into the milk collecting cup body 11.

[0050] In order to make the milk collection smoother, the stabilizing plate 3 also includes a milk collecting groove 36 extending downward from the plate body 31 to the milk collecting cup body 11, the air groove cup 34 is arranged around the milk collecting groove 36, the milk inlet 32 ​​is arranged through the groove bottom of the milk collecting groove 36, and the one-way valve 33 is fixed to the groove bottom of the milk collecting groove 36. The design of the milk collecting groove 36 can also make the air groove cup 34 better fit with the elastic airbag 4, which is more conducive to draining the milk in the air groove cup 34, and also better fit with the one-way valve 33 to increase air tightness.

[0051] In this embodiment, the one-way valve 33 is made of elastic material. Specifically, the one-way valve 33 includes a connecting column 331 that passes through the bottom of the milk collecting groove 36, a clamping wall 332 formed on the side of the connecting column 331 close to the elastic airbag 4, and a valve tongue 333 formed on the side of the connecting column 331 away from the elastic airbag 4. The valve tongue 333 is attached to the side of the bottom of the milk collecting groove 36 away from the elastic airbag 4 and completely covers the milk inlet 32.

[0052] Of course, the one-way valve 33 may also be a duckbill structure made of elastic material, and the principle is the same.

[0053] More preferably, the bottom of the milk collecting groove 36 is high in the middle and low on the periphery, and the milk inlet 32 ​​is located in the peripheral area of ​​the bottom of the milk collecting groove 36, which further improves the smoothness of milk collection.

[0054] In this embodiment, the elastic airbag 4 is partially located in the milk collecting groove 36, and a guide groove 41 is provided on the outer periphery of the elastic airbag 4, and the guide groove 41 extends from the bottom of the elastic airbag 4 to the two opposite side surfaces thereof, and the part of the guide groove 41 located on the side surface of the elastic airbag 4 is opposite to the connecting tube 35. The provision of the guide groove 41 can effectively prevent the elastic airbag 4 from shrinking incorrectly, guide it to shrink at the correct position to open the communication channel between the connecting tube 35 and the milk collecting groove 36, and improve the reliability of breastfeeding.

[0055] Compared with the related art, the breast pump of the utility model designs a breast collecting cup made of elastic material for collecting milk, a breast collecting cup body and a brassiere, and forms a detachable sealed connection through a stabilizing plate cover arranged on the open end of the breast collecting cup body, the breast collecting cup body forms a closed environment for collecting milk, and the milk duct of the brassiere is detachably sealed with the connecting pipe of the stabilizing plate, the air groove cup on the stabilizing plate is communicated with the connecting pipe, and an elastic air bag is arranged in the air groove cup, and the gas in the elastic air bag is extracted by the air pump assembly to form a negative pressure, thereby forming a negative pressure in the connecting pipe and the milk duct, so as to achieve the purpose of sucking out the milk, because the channel formed by the connecting pipe and the milk duct is shared by air suction and milk suction, the number of components is reduced, not only the structure is simple, but also easy to clean, and the air groove cup accommodating the elastic air bag is directly communicated with the milk inlet, so that the milk can enter the breast collecting cup body more smoothly; at the same time, because the breast collecting cup body and the stabilizing plate are an upper and lower mounting structure, the mold mark or the mounting mark can be hidden at the upper and lower junction, and the appearance is more beautiful.

[0056] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
