The improvement of this application scheme brings following advantage:

(1) the integrated breast shield of the embodiment of the application combines two independent parts of the diaphragm and the breast shield in the prior art into a whole, so that the integrated breast shield is changed into an integrally formed part, the number of parts of the breast pump is reduced, and the structure of the breast pump is simplified.

(2) The integrated breast pump cover is directly inserted into the breast pump for connection, and an air hole is omitted for communicating with an external vibration elastic diaphragm, so that the breast pump cover is more convenient to mount. The integrated breast shield solves the problems that in the prior art, the diaphragm is small in size, unstable in holding and not easy to mount, clean and store. The integrated breast shield is more convenient to install and clean.

(3) Diaphragm and breast shield among the prior art need be connected with the breast pump respectively, and the breast shield after the integration only needs an interface to be connected with the breast pump, compares two interface connection in prior art, and the gas tightness is better undoubtedly, greatly reduced from the possibility of interface gas leakage, reduced the loss of suction, improved suction phase to phase. And the diaphragm in the prior art is not stably placed and installed, so that the possibility of air leakage is increased.

(4) In the prior art, a diaphragm is driven by a piezoelectric air pump of a breast pump to elastically vibrate so as to form a negative pressure area in a breast shield, and further generate suction force, and the volume of the enlarged or raised diaphragm determines the negative pressure and the suction force of the negative pressure area. However, the diaphragm in the prior art is generally sheet-shaped, has a small area, is limited to the material of the diaphragm and the volume of the breast pump, and has a very limited volume which can be enlarged or protruded, thereby causing insufficient suction in a negative pressure region. This problem is generally solved by increasing the area of the diaphragm, but the diaphragm area cannot be too large, limited to the limited volume of the breast pump. And the diaphragm area is too large, which results in the volume of the cavity in which the negative pressure area is located being too large. Under the condition that the power of the piezoelectric air pump is not changed, the larger the volume of the cavity is, the smaller the negative pressure is, and the smaller the suction force is. The integrated breast shield provided by the application pumps away partial air in the negative pressure cavity through the piezoelectric air pump to form negative pressure, so that the cup-shaped suction part is elastically expanded or reduced under the action of the negative pressure, and negative pressure is also formed in the inner cavity of the breast shield main body. Compared with the sheet diaphragm in the prior art, the water cup-shaped suction part greatly increases the area which can be expanded or raised outwards, and further increases the volume which is expanded or raised outwards, thereby enhancing the negative pressure and suction force of the inner cavity of the breast shield main body. Meanwhile, the cross section of the cup-shaped suction part can be made smaller, the shape of the cup-shaped suction part is more fit with the shape of a breast near a nipple, the volume of a negative pressure area in the inner cavity of the breast shield main body is reduced, and negative pressure and suction are further enhanced.

Furthermore, the elastic part is sunken towards the inner cavity of the breast shield main body, and a pit is formed on the outer surface of the suction part. On one hand, the volume of the cavity in the negative pressure area can be occupied, and the negative pressure and the suction force are further enhanced; on the other hand, when the suction portion is protruded outward by the driving of the piezoelectric air pump, the volume of the protrusion can be increased, and the negative pressure and the suction force can be further enhanced.

Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The utility model is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.

Example 1

Referring to fig. 1-3, a breast pump includes a main body 2, an integrated breast shield 100 and a milk storage bottle 3.

The main machine 2 is mainly used for providing negative pressure for the integrated breast shield 100, and comprises a piezoelectric air pump driven by a motor, a negative pressure cavity 21, and necessary components such as a matched switch, an adjusting button, a control circuit, a battery and the like. The piezoelectric air pump uses a battery as a power supply and is driven by a motor and used for pumping air. The piezoelectric air pump is communicated with the vent hole 211 at the upper part of the negative pressure cavity 21 through an air pipe, and can pump partial air in the negative pressure cavity 21 when being started, so that the air pressure in the negative pressure cavity 21 is reduced, and negative pressure is formed in the negative pressure cavity 21. The side of the main body 2 is provided with a mounting opening for inserting and mounting the integrated breast shield 100. The bottom of the main machine 2 is provided with a milk outlet channel with one end communicated with the milk storage bottle 3, and the other end is communicated with a milk outlet 13 of the integrated milk sucking cover 100. In use, milk drawn from the internal cavity 14 of the integrated breast shield 100 flows through the milk outlet 13 and the milk channel to the milk storage bottle 3 for storage.

As shown in fig. 4, the integrated breast shield 100 includes a breast shield main body 1, and the breast shield main body 1 includes an absorption portion 11, a suction portion 12, a milk outlet 13, and a breast shield main body cavity 14. When the integrated breast shield 100 is mounted, the suction portion 11 faces outward, and the suction portion 12 extends into the negative pressure chamber 21, and then is mounted on the main body 2.

The breast shield main body 1 is manufactured by an integral forming process, and the whole body is in a hollow horn shape with one large end and the other small end. The breast shield body 1 is sealed except for the trumpet-shaped opening at the larger end and the milk outlet 13.

The suction part 11 is a larger end of the breast shield, is overall in the shape of a suction cup, and is made of an elastic material, such as silica gel, rubber, and the like, and preferably soft liquid silica gel is used. The suction portion 11 is adapted to snugly fit, and adhere to, the breast to form a relatively enclosed breast shield body cavity 14 within the breast shield body 1.

The suction portion 12 is a smaller end of the breast shield body 1, and is substantially cup-shaped. The suction portion 12 is provided with an elastic portion 122, and the elastic portion 122 is made of an elastic material, and it expands or contracts inward under the action of the air pressure difference. The inner cavity 14 of the breast shield main body is surrounded by the suction part 12, when the air pressure of the negative pressure cavity 21 becomes smaller due to the air suction of the piezoelectric air pump to form negative pressure, an air pressure difference is formed between the inner cavity 14 of the breast shield main body and the negative pressure cavity 21, the air pressure difference is directed to the negative pressure cavity 21 from the inner cavity 14 of the breast shield main body, the elastic part 122 expands or bulges outwards under the pressure of the air pressure difference, the volume of the inner cavity 14 of the breast shield main body becomes larger, the air pressure decreases, negative pressure is formed, and suction force is generated. Compared with the sheet diaphragm in the prior art, the water cup-shaped suction part 12 greatly increases the area which can be expanded or raised outwards, and further increases the volume which can be expanded or raised outwards, thereby enhancing the negative pressure and suction force of the inner cavity 14 of the breast shield main body. Meanwhile, the cross section of the cup-shaped suction part 12 can be made smaller, and the shape of the cup-shaped suction part 12 is more fit with the shape of a breast near a nipple, so that the volume of a negative pressure area in the inner cavity 14 of the main body of the breast shield is reduced, and the negative pressure and the suction force are further enhanced.

As shown in FIG. 5, the milk outlet 13 is provided in the middle of the lower end side of the breast shield body 1, preferably at a position corresponding to the position immediately below the nipple when the breast is inserted into the breast shield body. The milk outlet 13 is communicated with the inner cavity 14 of the breast shield main body.

The feeding bottle 3 is arranged at the bottom of the main machine 2 and comprises a feeding bottle body 31, a bottle cap and a duckbill valve 32. The feeding bottle main body 31 is used for storing milk, the lower end of the duckbill valve 32 is communicated with the feeding bottle main body 31 through the bottle cap, the upper end of the duckbill valve is communicated with the milk outlet channel of the host machine 2, and the duckbill valve 32 plays a role in preventing backflow.

The working principle of the application is as follows:

as shown in fig. 5, the integrated breast shield is mounted on the breast pump, and the suction part 12 at the smaller end is inserted into the negative pressure chamber 21 of the breast pump, so as to maintain the airtightness of the negative pressure chamber 21; the absorption part 11 with a larger horn-shaped opening at one end faces outwards so as to absorb the breast; the milk outlet 13 is communicated with the milk storage bottle 3 of the breast pump.

Then the absorption part 11 is attached to and absorbs the breast, and the nipple extends into the inner cavity 14 of the breast shield main body, so that the attachment of the absorption part 11 and the breast is ensured to be tight enough, no obvious leak occurs, and the air tightness of the inner cavity 14 of the breast shield main body is ensured. At this time, the breast shield main body 1 and the milk storage bottle 3 communicated with the milk outlet 13 form a closed cavity, the adsorption part 11 made of soft liquid silica gel is more suitable for the shape of the breast, can be closely attached and adsorbed on the soft skin of the breast, has good wrapping performance, further increases the air tightness of the cavity, and reduces the suction loss caused by air leakage.

Then the switch is pressed to start the breast pump, the piezoelectric air pump on the host machine 2 gradually pumps away the air in the negative pressure cavity 21, so that the air pressure in the negative pressure cavity 21 is reduced to form negative pressure, and further, an air pressure difference pointing to the suction cavity is generated between the inner cavity 14 of the breast shield main body and the negative pressure cavity 21. Under the pressure of the air pressure difference, the elastic portion 122 of the suction portion 12 expands or bulges outward, which causes the volume of the breast shield body cavity 14 to increase and the air pressure to decrease, i.e., the breast shield body cavity 14 generates a negative pressure relative to the atmosphere, thereby generating a suction force on the breast and the milk therein. On one hand, as the air pressure in the inner cavity 14 of the breast shield main body decreases, negative pressure is generated relative to the atmosphere, and the external atmosphere applies pressure to the breast shield main body 1 at the outer side of the breast shield main body 1, so that the adsorption part 11 in the breast shield main body 1 is attached to the breast more tightly. On the other hand, under the suction force generated by the negative pressure in the internal cavity 14 of the breast shield main body, the milk in the breast is sucked out from the breast, flows to the inner bottom of the breast shield main body 1, and further flows into the feeding bottle main body 31 through the milk outlet 13, the milk outlet passage and the duckbill valve 32.

Example 2

As a modification of embodiment 1, as shown in fig. 4, the suction part 12 is in the shape of a cup having a large upper part and a small lower part, and the larger upper part thereof is connected to the suction part 11, and the smaller lower part thereof protrudes into the negative pressure chamber 21. The suction unit 12 is composed of a reinforcing rib 121 and an elastic portion 122. The stiffener 121 is relatively stiff and includes a circular bottom member 1211 and four rib members 1212. The four rib members 1212 are arranged circumferentially and uniformly along the edge of the bottom member 1211 to form a generally cup-like configuration with the bottom member 1211. The elastic portion 122 is disposed between two adjacent rib members 1212, opposite sides of the elastic portion 122 are respectively connected to the adjacent rib members 1212, the bottom edge is connected to the bottom member 1211, and the elastic member is recessed inward, i.e. recessed toward the inner cavity 14 of the main body of the breast shield. The use of the relatively stiff ribs 121 maintains the shape of the main body of the suction portion 12, enhancing the structural strength of the suction portion 12. The inwardly recessed resilient portion 122, on the one hand, may occupy the volume of the breast shield body cavity 14, further enhancing the negative pressure and suction; on the other hand, when the suction portion 12 is expanded or projected outward by the piezoelectric air pump, the volume of the expansion or projection thereof can be increased, and the negative pressure and the suction force can be further enhanced.

Example 3

As an improvement to embodiment 1, in order to prevent the milk in the milk storage bottle 3 from flowing backwards, the milk outlet passage is provided with a step-shaped discontinuous step difference.

Example 4

As a modification of embodiment 1, as shown in FIG. 2, a breast shield support frame 4 is further included and is disposed between the main body 2 and the integrated breast shield 100, and the breast shield support frame 4 is used to make the softer integrated breast shield 100.
