Advantages of the Present Invention

[0037] (1) Silence: It can pass through the elastic inner recess connected to the software 1 in a mute state 102 is deformed, so that the cavity 11 achieves a negative pressure effect.
(2) Cost: When using the motor to pump air in the home appliance technology, it is necessary to match the pressure relief valve to relieve the negative pressure at the same time. There are many components to be controlled in the circuit design, and the circuit board is larger, and the present invention only passes through the coil 12 and the magnet 101 provided in the elastic inner recess 102, the circuit is relatively simple and the cost is also low.
(3) Weight: the present invention omits the motor and the pressure relief valve, and only replaces it with the coil 12, while the circuit board 1200 is smaller, lighter, and more suitable for wearable devices.
(4) Volume: the circuit board 1200 of the present invention is small and does not require a motor and a pressure relief valve, so the host 120 is made more compact.
(5) No leakage: the software 1 has the cavity 11 and can conform to the skin, and it is not easy to leak even if it is reclining. When reclining and expressing milk, the milk may flow down along the nipple. When the software 1 is in close contact with the skin, with the blocking device 103, the milk can flow into the collection tank 2 along the way.

[0038] Compared with the prior art, the present invention is more novel and progressive, wherein, compared with the invention patent of the Republic of China No. 1675675, (Japanese Patent No. 6691591) “invisible milking device”, the structure of the conventional product includes a main unit, a The extrusion unit, milk collecting bag, stop valve unit and drive unit pump air through the motor in the main unit, so that the negative pressure chamber of the software generates negative pressure and then compresses and deforms, which drives the milk collecting chamber to generate negative pressure to suck out the milk. To generate noise, special sound insulation treatment is required to reduce the troubles of users as mentioned above; the present invention completely mutes the formation process of negative pressure through the mute method of magnetic force, so the present invention is more novel and progressive; Compared with the patent of the invention in mainland China: CN103182103B “Electric Breast Pump”, the structure of the habit is different from that of the present invention, and the negative pressure generation method of the present invention only needs to be placed in the back end of the software 1. The elastic inner recess 102 of the cavity 11 is embedded in the magnet 101, and the coil 12 is used to pass current to generate a magnetic field to attract or repel the magnet 101 and to adjust the negative pressure, which saves components and achieves stability, comfort and static. Therefore, the present invention is more novel and progressive; the present invention is compared with the invention patent of “A Negative Pressure Relief Device on a Breast Pump” No. CN109125822A. There are differences in the invention. The difference is that the habit is a kind of moderator derived from the negative pressure pressurization too fast, and the breakthrough technology of the present invention is mainly to replace the air pumping, only the coil 12 can make the device larger. The width is simplified, and the mute effect is achieved, so the present invention has novelty and progress; the present invention is compared with the invention patent of “Electronic Negative Pressure Pulsator for Milking” with the Chinese Mainland Publication No. CN107980642A, which is an electronic negative pressure pulsator for milking, which has a relatively complex structure and has the same advantages as the present invention. There are obvious structural differences. The breakthrough technology of the present invention is mainly to replace the air pumping. Only the coil 12 can greatly simplify the device and achieve a mute effect. Therefore, the present invention is novel and progressive; in addition, the present invention can also be used in electric nasal aspirator, because many children are very afraid of the sound of the motor, so parents often need to struggle with children when using the current nasal aspirator.

[0039] Therefore, the present invention utilizes the software 1 to extend from the rear end to have the magnet at the inner end of the elastic inner concave portion 102 of 101, the front end surface of the elastic inner concave portion 102 forms a negative pressure cavity film and a stroking pro-emulsifying film 1022, and the rear end of the software 1 is provided with the coil 12 acting with the magnet 101; so as to achieve, that the coil 12 is driven by current to generate a magnetic field, the elastic inner recess 102 can be deformed and the cavity 11 can generate a mute negative pressure; the convenience of use and mute effect are effectively improved, and the conventional motor and pressure relief valve are omitted, which will greatly expand the industry. The utilization is novel and progressive.

[0040] In sum, it can be seen that the present invention has indeed achieved the desired effect under the breakthrough of the previous technology, and it is not easy for those who are familiar with the art to think about it. Furthermore, the present invention has not been disclosed before the application. It is novel and progressive, and obviously meets the application requirements for an invention patent. It is advisable to file an invention application in accordance with the law. It is urged that the bureau to approve this invention patent application to encourage inventions.

[0041] The above-mentioned embodiments are only for illustrating the technical ideas and characteristics of the present invention, and their purpose is to enable those who are familiar with the art to understand the content of the present invention and implement them accordingly. The scope of the patent, that is, all equivalent changes or modifications made in accordance with the spirit disclosed in the present invention shall still be covered within the scope of the patent of the present invention.
