Description

TECHNICAL FIELD

[0001] The present application relates to the field of breast pumps, in particular, a breast pump. BACKGROUND

[0002] Breastfeeding is currently the most scientific method of feeding infants, which is incomparable to formula milk and other complementary foods. As an auxiliary tool for breastfeeding, a breast pump can help lactating women collect milk to feed infants. Generally, a breast pump is composed of a breast cup (milk suction device) for sucking milk, a negative pressure generating device for providing suction, and a collection container for collecting milk.

[0003] In the prior art, the breast pump generally has the defects of too many overall components, cumbersome installation before the milk suction work, and complex structure of each component. The overall size of the existing breast pump after assembly is large, cannot realize hands-free use, the sealing effect between the components is poor, and the leakage of milk is prone to occur, which causes great inconvenience. CONTENT OF THE UTILITY MODEL

[0004] The content part of the present application is used to introduce the concept in a simple form, which will be described in detail in the specific embodiment part. The content part of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] In order to solve the technical problem of poor sealing effect between components and easy leakage of milk, some embodiments of the present application provide a breast pump, comprising:

[0006] A horn cover;

[0007] A cup cover is arranged on the horn cover and surrounds to form a milk storage cavity. The upper part of the cup cover is inwardly recessed and is in close contact with the horn cover to form a mounting area. A milk outlet is connected between the cup cover and the horn cover and is in communication with the milk storage cavity.

[0008] A main machine is fixed in the mounting area;

[0009] A fixing ring extending towards the horn cover is fixed in the cup cover. A gas permeation channel penetrating through the cup cover is formed in the side wall of the fixing ring and is in communication with the main machine;

[0010] A milk suction channel extending inwardly is formed in the horn cover. A connecting pipe is arranged on the milk suction channel. A deformation film is sealingly arranged between the connecting pipe and the fixing ring. The connecting pipe is provided with a duckbill valve in communication with the milk suction channel. One end of the duckbill valve is in communication with the milk storage cavity.

[0011] The deformed membrane extends outward at one end to form a ring, a first annular groove is formed on the fixing ring for inserting the ring, and a second annular groove is formed on the end face of the ring away from the fixing ring for inserting the connecting pipe.

[0012] The host of the application sucks or fills the internal air through the air passage, so that the deformed membrane deforms in the extension mode of the milk suction passage, controls the pressure in the milk suction passage, presses the user's breast by using the pressure, forces the milk to flow into the milk suction passage, enters the storage cavity through the duckbill valve, and finally flows out from the milk outlet. When the milk enters the storage cavity through the duckbill valve, the single-phase connectivity of the duckbill valve ensures that the milk in the storage cavity will not flow back, ensuring that the milk can be stored stably. Through the connection of the deformed membrane, the connecting pipe and the fixing ring, the sealing effect and the connection strength between the deformed membrane, the connecting pipe and the fixing ring can be improved. The deformed membrane is not easy to loosen during deformation.

[0013] Further, the connecting pipe is provided with a first protruding ring, and the second annular groove is provided with a first limiting portion for embedding the first protruding ring.

[0014] Further, one side end face of the first protruding ring is structured as a first inclined surface.

[0015] Further, the milk suction passage is provided with a mounting pipe in communication with the milk suction passage, and the mounting pipe is provided with a third annular groove for embedding the connecting pipe.

[0016] Further, the third annular groove is provided with a thread ring for connecting the connecting pipe.

[0017] Further, the mounting pipe is provided with an arc-shaped groove for embedding the connecting pipe.

[0018] Further, the cup cover is fixedly provided with a connecting ring extending towards one side of the horn cover, and the horn cover is provided with a connecting groove for embedding the connecting ring.

[0019] Further, the connecting ring is provided with a second protruding ring, and the connecting groove is provided with a second limiting groove for embedding the second protruding ring.

[0020] Further, one side end face of the second protruding ring is structured as a second inclined surface.

[0021] Further, the side end face of the storage cavity close to the mounting area has a slope portion, and the cross section of the slope portion gradually increases from the milk outlet towards the side of the storage cavity.

[0022] The application has the beneficial effect of providing a milk suction device with improved sealing effect. BRIEF DESCRIPTION OF DRAWINGS

[0038] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0039] Referring to Figures 1-6 , a breast pump, comprising a horn cover 1, a cup cover 2, and a main machine 3; the cup cover 2 is covered on the horn cover 1 to form a milk storage cavity 4, and a milk outlet 5 is formed between the cup cover 2 and the horn cover 1, and the milk outlet 5 is in communication with the milk storage cavity 4. The upper part of the cup cover 2 is inwardly recessed and is in close contact with the horn cover 1 to form a mounting area 6, and the main machine 3 is fixed in the mounting area 6 of the cup cover 2. A fixed ring 7 extending towards the horn cover 1 is fixed in the cup cover 2, a gas passage 8 penetrating through the cup cover 2 is formed on the side wall of the fixed ring 7, and the gas passage 8 is in communication with the main machine 3; the horn cover 1 is provided with a milk suction passage 9 extending inwardly, and the milk suction passage 9 is provided with a connecting pipe 10, a deformation film 11 is sealingly mounted between the connecting pipe 10 and the fixed ring 7, the connecting pipe 10 is provided with a duckbill valve 12 in communication with the milk suction passage 9, and one end of the duckbill valve 12 is in communication with the milk storage cavity 4. The working principle of the main machine 3 is consistent with that of the main machine 3 in the existing handrail-free breast pump, and reference can be made to the disclosure No. 202321192072.1, so it will not be described again. The deformation film 11 can be made of rubber, silicone or other materials that can form under external force and restore to the pre-deformation state after the external force disappears. The main machine 3 sucks or fills the internal air through the gas passage 8, so that the deformation film 11 deforms in the extension mode of the milk suction passage 9, controls the pressure in the milk suction passage 9, presses the user's breast by using the pressure, forces the milk to flow into the milk suction passage 9, then enters the milk storage cavity 4 through the duckbill valve 12, and finally flows out from the milk outlet 5. While the milk enters the milk storage cavity 4 through the duckbill valve 12, the single-phase communication of the duckbill valve 12 ensures that the milk in the milk storage cavity 4 will not flow back, ensuring that the milk can be stably stored.

[0040] The deformed membrane 11 extends outward at one end to form a circular ring 13, and the fixed ring 7 is provided with a first annular groove 14 for inserting the circular ring 13, and the end face of the circular ring 13 away from the fixed ring 7 is provided with a second annular groove 15 for inserting the connecting pipe 10. The connecting pipe 10 is provided with a first protruding ring 16, the second annular groove 15 is provided with a first limiting portion 17 for embedding the first protruding ring 16, and one side end face of the first protruding ring 16 is configured as a first inclined surface 18. Through the above arrangement, the sealing effect and the connection strength between the deformed membrane 11, the connecting pipe 10 and the fixed ring 7 can be improved, and the deformed membrane 11 is not easy to loosen during deformation.

[0041] The side end face of the milk storage cavity 4 close to the installation area 6 has a slope portion 19, and the cross section of the slope portion 19 gradually increases from the milk outlet 5 to the side of the milk storage cavity 4. This facilitates the discharge of the emulsion from the milk outlet 5, thereby improving the operation efficiency.

[0042] The milk suction channel 9 is provided with a mounting pipe 20 communicating with the milk suction channel 9, and the mounting pipe 20 is provided with a third annular groove 21 for embedding the connecting pipe 10. The third annular groove 21 is provided with a threaded ring 22 for strengthening the connection with the connecting pipe 10, and the mounting pipe 20 is provided with an arc-shaped groove 23 for facilitating the embedding of the connecting pipe 10. Through the above arrangement, the installation and disassembly of the connecting pipe 10 are facilitated, thereby facilitating the cleaning of the connecting pipe 10. At the same time, the arc-shaped groove 23 facilitates the limiting of the duckbill valve 12.

[0043] The cup cover 2 is fixedly provided with a connecting ring 24 extending toward the side of the horn cover 1, and the horn cover 1 is provided with a connecting groove 25 for embedding the connecting ring 24. The connecting ring 24 is provided with a second protruding ring 26, the connecting groove 25 is provided with a second limiting groove 27 for embedding the second protruding ring 26, and one side end face of the second protruding ring 26 is configured as a second inclined surface 28. Since the conventional breast pump is more likely to cause milk leakage when it is taken out after sucking milk due to the absence of multiple step structures. Therefore, through the above arrangement, the sealing effect and the connection strength between the cup cover 2 and the horn cover 1 can be improved, and the leakage of the emulsion can be avoided.

[0044] The above description is only some of the preferred embodiments of the present disclosure and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the application involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the above features are replaced with the technical features disclosed in the embodiments of the present disclosure (but not limited to) having similar functions to form technical solutions.
