Description

Technical Field

[0001] The utility model relates to the field of breast pumps, in particular to a neck-mounted breast pump that is convenient to operate. Background Art

[0002] A breast pump is a tool used to extract breast milk accumulated in the mammary glands and is a commonly used tool for lactating mothers.

[0003] There are many types of breast pumps. To facilitate milk extraction for mothers, there are breast pumps in the prior art that free the mother's hands. Such breast pumps are called hands-free breast pumps. Due to the built-in pump body structure, the entire weight of the breast pump will be borne by the breast, and it has a large volume, making it difficult for a bra to fasten this breast pump. When the large-volume breast pump is placed in the bra, the mother cannot move normally during milk extraction.

[0030] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. It should be noted that the terms used in the present utility model are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application.

[0031] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Therefore, the detailed descriptions of the embodiments of the present utility model provided in the following drawings are not intended to limit the scope of the present utility model to be protected, but only represent the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

[0032] Embodiment 1:

[0033] The neck-hanging breast pump is a breast pump that hangs the breast pump main unit around the neck in a neck-hanging form. However, the existing neck-hanging breast pumps all follow the structure of the original traditional double-sided breast pump, and the breast pump main unit for providing suction is made into a neck-hanging form, so that the mother can move freely by hanging the breast pump main unit around the neck. However, the existing neck-hanging breast pumps have many defects. For example, the center of gravity of the neck-hanging structure is unbalanced during transition, resulting in a feeling of center of gravity deviation when hanging the neck, and the neck-hanging structure is prone to falling off; since the suction pump for providing suction is arranged on one side of the neck-hanging structure, and suction-providing pipes will extend on both sides of the neck-hanging structure, this means that one side is far from the suction pump, and a longer pipe is required to connect to the suction pump when it is far from the suction pump, which will cause uneven suction provided; moreover, a display screen is provided on a normal breast pump main unit to display information such as suction levels. After the neck-hanging structure is worn, it is very difficult for the user to see the display screen on the neck-hanging structure. Therefore, the existing neck-hanging breast pumps are difficult to adjust and inconvenient to use. To solve the above problems, the neck-hanging breast pump with convenient operation provided in Embodiment 1 of the present utility model, as Figures 1 to 12 shown, includes a breast pump main unit 1; the breast pump main unit 1 includes an air pump 11, a battery 12, a valve body 13, a neck-hanging structure 14, a control board 16 and a voice broadcast device 17; first accommodating shell parts 141 and second accommodating shell parts 142 are respectively arranged at both ends of the neck-hanging structure 14; a set of the air pump 11, the battery 12 and the valve body 13 are respectively arranged in the first accommodating shell part 141 and the second accommodating shell part 142; in each set of the air pump 11, the battery 12 and the valve body 13, the air pump 11 is electrically connected to the battery 12; the valve body 13 is electrically connected to the battery 12; the air inlet of the air pump 11 is communicated with the air outlet of the valve body 13; air vents 15 are arranged on both the first accommodating shell part 141 and the second accommodating shell part 142; the air inlet of the valve body 13 is hermetically communicated with the air vent 15; the control board 16 and the voice broadcast device 17 are both arranged inside the first accommodating shell part 141; a plurality of buttons 143 are arranged on the shell of the neck-hanging structure 14; the buttons 143 are electrically connected to the control board 16; the voice broadcast device 17 is electrically connected to the control board 16; the air pump 11 is electrically connected to the control board 16; the valve body 13 is electrically connected to the control board 16; the battery 12 is electrically connected to the control board 16.

[0034] When the convenient-to-operate neck-worn breast pump provided in Embodiment 1 of the present utility model is in use, the mother fixes the neck-wearing structure 14 around the neck, connects a pipeline at the ventilation openings 15 of the first containment shell portion 141 and the second containment shell portion 142, and places a breast pump shield at the other end of the pipeline on the breast to complete the wearing (the structure of the neck-wearing structure belongs to the prior art, and a breast pump main body and a breast pump disclosed in Chinese Patent Application No. 202311361803.5 mentioned in the background art have been made public). The mother realizes the human-computer interaction with the control board 16 by pressing the button 143 outside the first containment shell portion 141, and controls each air pump 11 and valve body 13 inside the first containment shell portion 141 and the second containment shell portion 142 through the control board 16. The air pump 11 operates and controls the valve body 13 to open, so that the air pump 11 can provide suction to the ventilation opening 15, thereby providing suction to the breast pump shield at the ventilation opening 15. When the control board 16 is manipulated through the button 143, the voice broadcast device 17 electrically connected to the control board can broadcast the gear size after the interaction button 143 in real time, facilitating the mother to know the suction gear; compared with the prior art, the device provided in this embodiment, on the one hand, can facilitate the mother to perform other operations when using the breast pump (the main body of the neck-wearing structure 14 enables the mother to conveniently carry the breast pump main body without being restricted by the fixed breast pump main body in her own actions), and at the same time, the mother can know the suction gear of the breast pump main body 1 through the broadcast of the voice broadcast device 17 for convenient adjustment; on the other hand, as the air pump 11, battery 12, and valve body 13, which are the heaviest in the breast pump main body, are both provided in the first containment shell portion 141 and the second containment shell portion 142, this makes the gravity at both ends of the neck-wearing structure 14 balanced, making the neck-wearing structure 14 not easily fall off; compared with only setting one air pump 11, in this embodiment, two air pumps 11 are respectively used to provide suction to the mother's two breasts, which facilitates the mother to control and adjust the suction required for the two breasts. The control board 16 can respectively record the suction magnitudes of the two air pumps 11 during the last use, and automatically call the suction magnitudes of the suction pumps on both sides when used next time, which avoids the mother having to adjust the suction provided by the air pump 11 through the control board 16 every time she breastfeeds the two breasts to make the suction at the two breasts appropriate.

[0035] The convenient-to-operate neck-worn breast pump provided in the embodiment of the present utility model solves the problem of inconvenient control when using a neck-worn breast pump in the prior art, and can facilitate the mother to control the breast pump when using the neck-worn breast pump.

[0036] As a preferred solution, in this embodiment, a plurality of sound holes 1411 are formed in the first accommodating shell portion 141; the sound emitting module of the voice broadcast device 17 faces the sound holes 1411. The sound holes 1411 can transmit the sound of the language broadcast device 14 located inside the first accommodating shell portion 141, reducing the blockage of the sound emitted by the language broadcast device 14 by the housing structure of the first accommodating shell portion 141, thereby facilitating the mother to know the suction gear information.

[0037] Since the original intention of the neck-hanging breast pump is to free the mother's hands during the breast pumping process so that the mother can move normally, the existing common breast pump shields that need to be held by hand are not what this embodiment requires. In the comparative documents provided in the background art, there is no disclosure of the specific structure description of the breast pump shield 2. If the common hands-free breast pump in the prior art is adopted (such as the hands-free breast pump that is easy to clean disclosed in Chinese Patent Application No. 202321014162.1), then there are problems with this breast pump: since it needs to be built into the bra during use and the bra is used to press the hands-free breast pump towards the breast, it is difficult to control the buttons on the surface of the breast pump; there is also the problem that since the hands-free breast pump includes structures such as a suction pump and a control panel valve, the overall volume of the hands-free breast pump is very large, and it is also inconvenient for the mother to move when placed between the bra and the breast. To solve this problem, in this embodiment, there are also two breast pump shields 2 and a pipe 3; the ventilation ports 15 of the first containment shell part 141 and the second containment shell part 142 are respectively connected to a breast pump shield 2 through a pipe 3; the breast pump shield 2 includes a funnel-shaped base 21, a tee 22, and a hood-shaped outer shell 23; the outer shell 23 is detachably fixed on the base 21; when the outer shell 23 is fixed on the base 21, the small funnel opening of the base 21 faces the hood-shaped inner cavity of the outer shell 23; the large funnel opening of the base 21 is hermetically attached to the hood-shaped opening of the outer shell 23; the tee 22 is arranged in the space formed by the outer shell 23 and the base 21; the tee 22 includes a milk inlet 221, a negative pressure port 222, and a milk outlet 223; the small funnel opening of the base 21 is hermetically connected to the milk inlet 223 of the tee 22; there is a ventilation hole 24 on the outer shell 23; the ventilation hole 24 is hermetically connected to the negative pressure port 222; the ventilation hole 24 and the negative pressure port 222 are separated by a flexible membrane 25; the milk outlet 223 is connected to the inlet of a duckbill valve 26; the outlet of the duckbill valve 26 is inside the inner cavity of the outer shell 23; the ventilation hole 24 is detachably connected to the pipe 3.This embodiment provides a structure of a breast pump shield 2, which eliminates the structures of an air pump, a valve, and a control panel lamp, and is convenient to be built into the space between a bra and the breast. When wearing specifically, the large funnel opening of the base 21 faces and tightly adheres to the mother's breast, the nipple of the breast faces the small funnel opening of the base 21, and the cover shape of the outer shell 23 tightly adheres to the inner side of the bra. The bra applies pressure to the outer shell 23, so that the entire breast pump shield 2 applies pressure towards the breast, thereby making the base 21 tightly adhere to the breast. The air vent 15 and the negative pressure port 222 of the tee 22 are connected by a pipeline 3 (the function of the flexible membrane 25 is to prevent the milk flowing into the tee from flowing into the breast pump main unit 1 along the pipeline), so that the suction force is provided to the tee 22 along the pipeline 3, and then provided to the base 21 connected to the milk inlet 221. The nipple of the breast faces the milk inlet 221. After being subjected to the suction force, milk is secreted from the nipple and flows into the sealed tee 22. When a certain amount of milk accumulates in the tee 22, the duckbill valve opens due to the gravity of the milk, and enters the space enclosed between the outer shell 23 and the base 21 through the duckbill valve 26 from the milk outlet 223 for storage; this embodiment improves the breast pump shield 2, reduces the volume of the breast pump shield 2 (eliminating structures such as the solenoid valve of the suction pump control panel), and enables the breast pump shield 2 to be better arranged in the bra (the cover-shaped outer shell 23 is designed to better fit the bra), so that the mother can wear a breast pump shield 2 with a small structure in front of the chest, which has little impact on movement, thus facilitating the mother's activities during the milk pumping process.

[0038] As a preferred solution, in this embodiment, a rigid negative pressure chamber 231 is provided on the inner side of the cover shape of the outer shell 23; a cavity is provided in the negative pressure chamber 231; an air vent 24 and a communication hole 2311 are provided on the negative pressure chamber 231; the air vent 24 and the communication hole 2311 communicate the inside and outside of the cavity of the negative pressure chamber 231; the communication hole 2311 is hermetically connected to the negative pressure port 222; the flexible membrane 25 hermetically divides the cavity of the negative pressure chamber 231; the air vent 24 and the communication hole 2311 are separated on both sides of the flexible membrane 25. When the breast pump main unit 1 provides suction force, the suction force is provided to the air vent 24 along the pipeline 3, so that the gas inside one side space of the flexible membrane 25 (the space between the negative pressure chamber 231 and the space provided with the air vent 24) decreases, thereby causing the flexible membrane 25 to deform, and the volume of the other side space of the flexible membrane 25 (the space of the negative pressure chamber 231 provided with the communication port 2311) increases, so that the air pressure in the tee 22 connected to the communication port 2311 decreases, and thus suction force is generated at the base 21 connected to the milk inlet 221 of the tee 22.

[0039] To facilitate the removal of the milk in the breast pump shield 2, in this embodiment, the outer shell 23 and the base 21 are rotatably connected by a hinge; a slot 232 is provided on the outer shell 23; an elastic plug-in block 211 is provided on the base 21; the plug-in block 211 matches the slot 232; by pressing the plug-in block 211, the plug-in block 211 can be inserted into the slot 232; by stopping pressing the plug-in block 211, the plug-in block 211 can elastically deform itself and be clamped in the slot 232. The pipeline 3 and the ventilation hole 24 on the breast pump shield 2 are detachably connected. After the milk pumping is completed, the pipeline 3 needs to be separated from the ventilation hole 24 first, and then the bra is taken off, and the breast pump shield 2 is taken out from between the bra and the breast. Control the outer shell 23 of the breast pump shield 2 with the cover body (the side for abutting against the bra) facing downwards and the cover opening of the cover body of the outer shell 23 facing upwards. Press the plug-in block 211 to deform the plug-in block 211. After taking out the plug-in block 211 from the slot 232, rotate the base 21 relative to the outer shell 23, so as to separate the base 21 from the outer shell 23. The milk is in the cover-shaped outer shell 23. After storing the milk in the outer shell 23 in a milk bottle by pouring or other means, the work of milk removal is completed.

[0040] To facilitate the separation of the base 21 from the outer shell 23, in this embodiment, a first leverage baffle 233 is provided on the outer shell 23; the first leverage baffle 233 is fixed on the cover-shaped outer wall of the outer shell 23; a second leverage baffle 212 is provided on the base 21; the second leverage baffle 212 is fixed on the outer extension of the large opening of the funnel of the base 21. The first leverage baffle 233 and the second leverage baffle 212 are respectively fixed on the base 21 and the outer shell 23, so that during the process of rotating the base 21 relative to the outer shell 23 by the user, the user can apply reverse forces to the first leverage baffle 233 and the second leverage baffle 212 to achieve the separation of the base 21 and the outer shell 23.

[0041] As a preferred solution, in this embodiment, the first force - assisting baffle 233 and the second force - assisting baffle 212 have a supporting edge that is flush on one side; the breast pump shield 2 can be stably placed on a horizontal plane through the supporting edges of the first force - assisting baffle 233 and the second force - assisting baffle 212; a milk - pouring opening 213 is provided on the base 21; the milk - pouring opening 213 is arranged at the top of the base 21 after the breast pump shield 2 is stably placed through the supporting edge. Each time the milk is taken out from the breast pump shield 2, it is necessary to separate the base 21 from the outer shell 23, and such an operation is very troublesome because during the process of separating the base 21 from the outer shell 23, it is necessary to always pay attention to avoiding the spillage of milk. Since the posture of the breast pump shield 2 is relatively fixed after the mother wears the breast pump shield 2, in this embodiment, the milk - pouring opening 213 is provided on the base 21 to facilitate the removal of milk from the breast pump shield 2 after milk suction. Since the milk - pouring opening 213 is provided, to avoid the leakage of milk from the milk - pouring opening 213, the milk - pouring opening 213 should be avoided facing downwards. Therefore, in this embodiment, the first force - assisting baffle 233 and the second force - assisting baffle 212 are improved so that the first force - assisting baffle 233 and the second force - assisting baffle 212 can also play a role in supporting the stable placement of the entire breast pump shield 2.
