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.

[0020] The following will describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Therefore, the detailed description of the embodiments of the present utility model provided in the following drawings is not intended to limit the scope of the claimed present utility model, but only represents the selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.

[0021] Embodiment 1:

[0022] A breast pump shield is a breast pump accessory fixed on the mother's breast. Its purpose is to fit tightly against the mother's breast and allow breast milk to be stored in the breast pump shield. The function of the breast pump shield in the prior art reference is to allow the mother to free her hands and avoid the mother having to constantly press a conventional breast pump shield against the breast to maintain stability. It only needs to place the breast pump shield in the bra. After the mother wears the bra, the breast pump shield is pressed by the bra and fits tightly against the mother's breast. However, the breast pump shield in the prior art is just a simple cover shape and does not have a special fixing structure to stably place it on a horizontal plane. This means that after the mother finishes breast pumping, she cannot simply take out one breast pump shield containing milk and then immediately take out another breast pump shield, because the breast pump shield containing milk may leak the milk inside due to unstable placement. Therefore, for the breast pump shield in the prior art, the mother needs to pour the milk inside it into a storage container after taking out one breast pump shield and then take out another breast pump shield. Such an operation is inconvenient. To solve the above problems, the breast pump shield that can store milk provided in Embodiment 1 of the present utility model is as Figures 1 to 6As shown, it includes a funnel-shaped base 1, a three-way joint 2, and a hood-shaped outer shell 3; the outer shell 3 is detachably fixed to the base 1; when the outer shell 3 is fixed to the base 1, the small opening of the funnel of the base 1 faces the inner cavity of the hood shape of the outer shell 3; the large opening of the funnel of the base 1 is hermetically attached to the hood-shaped opening of the outer shell 3; the three-way joint 2 is arranged in the space formed by the outer shell 3 and the base 1; the three-way joint 2 includes a milk inlet 21, a negative pressure port 22, and a milk outlet 23; the small opening of the funnel of the base 1 is hermetically connected to the milk inlet 21 of the three-way joint 2; a ventilation hole 31 is provided on the outer shell 3; the ventilation hole 31 is hermetically connected to the negative pressure port 22; a flexible membrane 32 is arranged between the ventilation hole 31 and the negative pressure port 22 for isolation; a duckbill valve 4 inlet is connected to the milk outlet 23; the outlet of the duckbill valve 4 is located in the inner cavity of the hood shape of the outer shell 3; a first force-applying baffle 5 is provided on the outer shell 3; the first force-applying baffle 5 is fixed to the outer wall of the hood shape of the outer shell 3; a second force-applying baffle 6 is provided on the base 1; the second force-applying baffle 6 is fixed to the extension of the large opening of the funnel of the base 1; the first force-applying baffle 5 and the second force-applying baffle 6 have a supporting edge that is flush on one side; a milk pouring port 11 is provided on the base 1; the milk pouring port 11 is arranged at the top of the base 1 after the breast pump shield is stably placed through the supporting edge.

[0023] When the breast pump shield capable of storing milk provided by the embodiment 1 of the utility model is used, the two breast pump shields are respectively placed close to the two breasts of the mother, and are fixed to the breasts by wearing a bra, the large funnel opening of the base 1 faces the breasts, and the large inner wall of the funnel opening of the base 1 is close to the breasts, the shield-shaped outer wall of the shell 3 is closely positioned with the inner wall of the brassiere, the vent 31 is connected to the external breast pump host through a pipeline, and the external breast pump host provides suction, and the tee 2 worn through the pipeline, after the negative pressure port 22 of the tee 2 is subjected to suction, the air pressure inside the tee 2 changes, thereby causing the air pressure of the base 1 connected to the tee 2 to change (after the mother puts the base 1 close to the breast, the breast, the inner wall of the funnel of the base 1, and the inside of the tee form a closed space, this The enclosed space is connected to the outside at two places, one is the negative pressure port 22 of the three-way, and the other is the milk outlet 23 of the three-way. Since the milk outlet 23 is provided with a duckbill valve 4, when the duckbill valve 4 keeps the outlet closed, the negative pressure port 22 is subjected to suction, and the air pressure in the enclosed space becomes smaller, thereby sucking the milk from the breast at normal air pressure). After the milk flows into the three-way 2, it flows to the duckbill valve 4 and accumulates. When the milk accumulates in the duckbill valve 4, the gravity of the milk causes the duckbill valve 4 to open, and the milk flows into the space between the base 1 and the shell 3. By tilting the breast pump shield, the milk pouring port 11 is facing downward, and the milk flows out of the breast pump shield from the milk pouring port 11; the above structure is in the background technology, such as Chinese patent application No. 202321675515.2 A wearable breast pump cup assembly has been disclosed. Different from the reference document, the device provided in this embodiment is provided with a first lever baffle 5 and a second lever baffle 6 on the base 1 and the shell 3. Since the base 1 and the shell 3 are detachably connected (because after each milking is completed and the milk in the breast pump shield is taken out, the inside needs to be opened for cleaning and disinfection), the first lever baffle 5 and the second lever baffle 6 can facilitate the mother to apply reverse forces to the base 1 and the shell 3, thereby facilitating the separation of the base 1 and the shell 3. The first lever baffle 5 and the second lever baffle 6 also have a support edge flush with one side, so that the breast pump shield can be stably placed on a horizontal surface (such as a desktop) through the common support edge. Therefore, after the mother finishes expressing breast milk, she can place one breast pump shield stably on the table, and then immediately take out the other breast pump shield and place it on the table. After putting on clothes, she can then pour the milk in the breast pump shield into the milk storage bottle for storage. The breast pump shield is stably placed on the table because the milk pouring port 11 is vertically facing upwards, which can prevent the milk from leaking out due to the tipping of the breast pump shield. Therefore, compared with the breast pump shield in the prior art that easily causes the milk to tip over, the milk in the breast pump shield (when the other breast pump shield is fixed on the mother's breast) is taken out and stored first, and then the other breast pump shield is taken out and the milk is stored in time, and then clothes are put on. The device provided by this embodiment allows the mother to conveniently use the breast pump shield.

[0024] The breast pump shield provided by the embodiment of the present utility model can store milk, which solves the problem that the breast pump shield in the prior art is inconvenient to take out, and can facilitate the mother to take out the breast pump shield in the bra after using the breast pump to pump milk.

[0025] As a preferred solution, in this embodiment, a rigid negative pressure chamber 33 is provided on the inner side of the cover shape of the outer shell 3; a cavity is provided in the negative pressure chamber 33; a ventilation hole 31 and a communication hole 331 are provided on the negative pressure chamber 33; the ventilation hole 31 and the communication hole 331 communicate the inside and outside of the cavity of the negative pressure chamber 33; the communication hole 331 is hermetically communicated with the negative pressure port 22; the flexible membrane 32 hermetically divides the cavity of the negative pressure chamber 33; the ventilation hole 31 and the communication hole 331 are separated on both sides of the flexible membrane 32. When the breast pump main unit provides suction, the suction is provided to the ventilation hole 31 along the pipeline, so that the gas in the space on one side of the flexible membrane 32 (the side of the negative pressure chamber provided with the ventilation hole) is reduced. To maintain air pressure balance, the flexible membrane 32 deforms toward the side of the ventilation hole 31, so that the space on the other side of the negative pressure chamber 33 (the space of the negative pressure chamber 33 provided with the communication hole 31) becomes larger and the air pressure becomes smaller, so that suction is generated at the base 1 communicated with the milk inlet 21 of the tee 2, and the mother's breast is subjected to suction, and the milk flows out of the breast into the tee 2.

[0026] Since the base and the outer shell in the comparative document have a very high connection strength to ensure sealing, a great deal of force needs to be applied when separating the base from the outer shell, which will cause vibration of the breast pump shield. When the milk pouring port is blocked and milk cannot be poured out normally, separating the base from the outer shell easily causes milk to spill. To facilitate the opening of the base 1 relative to the outer shell 3, in this embodiment, the outer shell 3 and the base 1 are rotatably connected by a hinge; a slot 34 is provided on the outer shell 3; an elastic plug-in block 12 is provided on the base 1; the plug-in block 12 matches the slot 34; by pressing the plug-in block 12, the plug-in block 12 can be deformed and inserted into the slot 34; by stopping pressing the plug-in block 12, the plug-in block 12 can elastically deform itself and be clamped tightly in the slot 34. The external breast pump main body is communicated with the ventilation holes 31 on the breast pump shield through a pipeline, and the pipeline and the ventilation holes 31 are detachably connected. After milk pumping is completed, the pipeline needs to be separated from the ventilation holes 31 first, then the bra is taken off, and the breast pump shield is taken out from between the bra and the breast. The cover body (the side for abutting against the bra) of the outer shell 3 of the breast pump shield is controlled to face downward, and the cover opening of the cover body of the outer shell 3 faces upward. By pressing the plug-in block 12 to deform the plug-in block 12, after taking out the plug-in block 12 from the slot 34, the base 1 is rotated relative to the outer shell 3, so as to separate the base 1 from the outer shell 3. The milk is in the cover-shaped cavity of the cover body of the outer shell 3, and the milk in the outer shell 3 is stored in a milk bottle by pouring or other means to complete the work of taking out the milk. This is a method for taking out the milk in the breast pump shield when the milk pouring port 11 is blocked. The structure disclosed in the comparative document provided in the background art is such that the method of separating its base from the outer shell easily generates violent vibration, and the milk is easily spilled due to the vibration. However, the device provided in this embodiment can stably fix the outer shell 3 and open the base 1 relative to the outer shell 3 by rotating the base 1 relative to the outer shell 3. Since ensuring the tight connection between the base 1 and the outer shell 3 is determined by the deformation of the plug-in block 12, and when a person applies pressure to the plug-in block 12, the base 1 and the outer shell 3 remain in close contact, so an instantaneous force will not be directly provided to the base 1 and the outer shell 3 to cause them to be separated instantaneously, resulting in the spilling of milk. After the plug-in block 12 is deformed and taken out from the slot 34, the mother can slowly turn and separate the base 1 relative to the outer shell 3 at the hinge, so the separation process between the base 1 and the outer shell 3 is smoother, and the milk in the outer shell 3 can be stable and not easily spill out from the cavity of the cover body of the outer shell 3.
