Slot 87a may be a USB standard interface, such as a Type-C standard interface, and hole 87b is a ventilation hole. The insertion slot 87a and the connection hole 87b are provided on the side surface of the upper case 81. The slot 87a is used for the first conduit 51 to insert so that the host 8 is connected to the electrical contact 53 on the cover 50. The hole 87b is used for inserting the second conduit 52 so that the host 8 is connected to the opening 54 of the cover 50. The first conduit 51 is connected to a power module 84, and the power module 84 is controlled by the control unit 83 to adjust the output power. The light guide unit 88 is disposed on the top of the upper housing 81 to make the brightness of the display unit 86 more uniform and soft without generating a dark sunlight effect around the light.

In addition, the main unit 8 may further include a lower case 85. The lower housing 85 has a receiving groove 851. The upper housing 81 may cover the receiving groove 851 to shield the receiving portion 87. In another embodiment of the present invention, the inside of the containing groove 851 may be divided into a plurality of containing spaces for containing the breastshield 2, the heating shield 3 and the conduit module 5.

Please refer to FIG. 2 and FIG. 7-1 to FIG. 7-3. The utility model is connected with a duct module 5, a breast pump cover body 2, a heating cover body 3 and a milk collecting bottle 4 through an adapter 1. The conduit module 5 is further connected to a host 8 having a receiving groove 851. The power module 84 in the host 8 transmits power to the electric heating unit 32 through the first conduit 51 to heat it and operate the pump 82. The pump 82 is operated to generate suction to draw air from the interior of the cavity of the adapter 1 through the second conduit 52 via the opening 54. Since the diaphragm member 6 is located between the first cavity 11 and the cover 50, air communication between the opening 54 and the first through hole 14 is blocked. Therefore, the pump 82 actually draws air from the inner space between the cover 50 and the diaphragm 6 when generating suction force, so that pressure variation occurs inside the cavity of the adaptor 1.

In more detail, when the female attaches the breastshield 2 to the breast, the suction force of the pump 82 can also be adjusted by the control unit 83. The suction of the pump 82 draws air from the interior volume between the cover 50 and the diaphragm member 6, so that the volume of the gas in the interior volume is reduced, and the balance between the volume of the gas in the interior volume and the volume of the gas in the cavity of the adapter 1 is changed. The equalized change in gas volume produces a change in pressure in the cavity of the adapter 1. The pressure change causes the diaphragm member 6 to undergo deformation by periodic contraction and expansion. The pressure in the cavity of the adapter 1 is changed, so as to generate suction to stimulate the breast to suck milk. The expressed milk enters the adaptor 1 cavity via the breastshield body 2. When the diaphragm member 6 continues to contract and expand, the irregular height of the rib 55 (due to the presence of the semi-cylindrical body 55 a) prevents the diaphragm member 6 from completely adhering to the surface of the opening 54 during contraction, thereby preventing a vacuum-tight state. Then, due to the barrier action of the membrane 6, the milk does not pass through the opening 54 to the second conduit 52, but instead passes through the second through-hole 15 to the collection bottle 4 for storage. Furthermore, the motorized breast pump 100 may further include a valve body 7, the valve body 7 being disposed in the second through hole 15. The milk passes through the valve body 7 together with the second through hole 15. The valve body 7 is a duckbill valve to prevent milk entering the milk collection bottle 4 from being sucked out by suction.

To sum up, the utility model provides an electronic breast pump utilizes two independent subassemblies that can make up/disassemble to breast pump cover body and heating cover body, solves among the prior art electric heating element embedded in breast pump cover body and causes the shortcoming of easy damage. The utility model discloses an electronic aspirator and through pluggable receiving part structure, let the user pull out pipe module from the receiving part after finishing using. Then the duct module, the breast pump cover body and the heating cover body are accommodated in the accommodating groove of the host machine.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Modifications and variations can be made to the above-described embodiments by those of ordinary skill in the art without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be as set forth in the claims.
