In the present invention, the motorized breastpump 100 may also include a host 8. Please refer to fig. 7-1 to 7-3. Fig. 7-1 is an external view of the host, fig. 7-2 is an exploded view of the host, and fig. 7-3 is a functional view of the host. The host 8 may include an upper housing 81, a pump 82, a control unit 83, and a power module 84. The pump 82 is provided inside the upper housing 81. The control unit 83 is a knob-type or button-type switch disposed on the surface of the upper housing 81 for controlling the operation of the pump 82 and the operation of the electric heating unit 32. The power module 84 is disposed inside the upper housing 81 for providing power to the heating cover 3 and the pump 82.

The host 8 may further include a display unit 86, a slot 87a, a connection hole 87b, and a light guide unit 88. The display unit 86 is disposed on a surface of the upper case 81 and surrounds the control unit 83. The display unit 86 can emit light, such as an LED lamp post, to display the power supply status of the power module 84 and the heating status of the electric heating unit 32. 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 containing groove 851 may be internally divided into a plurality of containing spaces for containing the breastshield body 2, the heating shield body 3 and the conduit module 5.

Please refer to FIG. 2 and FIG. 7-1 to FIG. 7-3. The invention is characterized in that a duct module 5, a breast pump cover body 2, a heating cover body 3 and a milk collecting bottle 4 are connected 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.

In summary, the electric breast pump provided by the invention utilizes the breast pumping cover body and the heating cover body which are combined/disassembled, and solves the defect that the electric heating component is embedded in the breast pumping cover body in the prior art to cause easy damage. The electric sucker enables a user to pull out the catheter module from the receiving part after use through the structure of the receiving part which can be inserted and pulled out. 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 foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the 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 scope of the invention should be determined from the following claims.
