In the present invention, the electric breast pump 100 may include a host 8. Please refer to Figure 7-1 to Figure 7-3. Figure 7-1 is a schematic diagram of the appearance of the host, Figure 7-2 is an exploded schematic diagram of the host, and Figure 7-3 is a functional schematic diagram of the host. The host 8 may include an upper casing 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 and button type switch, which is arranged on the surface of the upper casing 81 to control the operation of the pump 82 and the operation of the electric heating unit 32. The power module 84 is arranged inside the upper casing 81 to provide power for the heating cover 3 and the pump 82.

The host 8 may further include a display unit 86, a slot 87a, a contact hole 87b, and a light guide unit 88. The display unit 86 is provided on the surface of the upper casing 81 and surrounds the control unit 83. The display unit 86 can be a luminous element, such as a luminous LED lamp post, etc., to display the power supply status of the power module 84 and the heating status of the electric heating unit 32. The socket 87a can be a USB interface, such as a Type-C interface, and the socket 87b is a vent hole. The slot 87a and the contact hole 87b are provided on the side surface of the upper housing 81. The slot 87a is for inserting the first pipe 51 so that the host 8 is connected to the electrical contact 53 on the cover 50. The connecting hole 87 b is used for the insertion of the second pipe 52 so that the host 8 is connected to the opening 54 on the cover 50. The first conduit 51 is connected to the 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 arranged on the top of the upper casing 81 to make the luminosity of the display unit 86 more uniform and soft, and will not produce the darker sunlight effect around the light.

In addition, the host 8 may also include a lower housing 85. The lower shell 85 has a receiving groove 851. The upper shell 81 can be covered on the accommodating groove 851 to cover the receiving part. In another embodiment of the present invention, the interior of the accommodating groove 851 can be divided into a plurality of accommodating spaces for accommodating the breast shield body 2, the heating shield body 3 and the catheter module 5.

Please refer to Figure 2 and Figure 7-1 to Figure 7-3 together. In the present invention, the catheter module 5, the breast shield body 2, the heating shield body 3 and the milk collection bottle 4 are connected through the adapter seat 1. The catheter module 5 is additionally connected to a host 8 with a receiving slot 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 the pump 82 is operated. The pump 82 generates suction during operation, and extracts air from the cavity of the adapter 1 through the opening 54 through the second duct 52. Since the diaphragm 6 is located between the first cavity 11 and the cover 50, the air circulation between the opening 54 and the first through hole 14 is blocked. Therefore, help When the Pu 82 generates suction, it actually extracts air from the internal accommodating space between the cover 50 and the diaphragm 6, so that the pressure inside the cavity of the adapter 1 changes.

In more detail, when a woman attaches the breastshield body 2 to the breast, the suction force of the pump 82 can also be adjusted through the control unit 83. The suction of the pump 82 extracts the air in the internal accommodating space between the cover 50 and the diaphragm 6 so that the gas volume in the internal space becomes smaller, thereby changing the gas volume in the internal space and the gas in the cavity of the adapter 1 Balance of volume. The balanced change of the gas volume causes the pressure in the cavity of the adapter 1 to change. The pressure change will cause the diaphragm member 6 to undergo periodic contraction and expansion deformation. The pressure in the cavity of the adapter 1 is changed, and then suction is generated to stimulate the breast and suck milk. The sucked milk enters the cavity of the adapter 1 through the breast shield body 2. It should be noted that when the diaphragm 6 continues to shrink and expand, the irregular and equal height of the ribs 55 (due to the presence of the semi-cylindrical body 55a) will prevent the diaphragm 6 from being completely attached to the surface of the opening 54 when it is contracted. , To prevent the formation of a vacuum tight state. Then, due to the blocking effect of the diaphragm 6, the milk will not enter the second duct 52 through the opening 54, but will enter the milk collection bottle 4 through the second through hole 15 for storage. In addition, the electric breast pump 100 may further include a valve body 7 provided in the second through hole 15. When the milk passes through the second through hole 15, it passes through the valve body 7 together. The valve body 7 is a duckbill valve to prevent the milk entering the milk collection bottle 4 from being sucked out by suction.

In summary, the electric breast pump provided by the present invention utilizes two separate components, a breast shield body and a heating shield body, which can be combined/disassembled, to solve the problem of easy damage caused by the electric heating element embedded in the breast shield body in the prior art. Disadvantages. The electric suction device of the present invention also has a pluggable receiving part structure, allowing the user to remove the catheter module from the receiving part after use. Then, the catheter module, the breast shield body and the heating shield body are stored together in the accommodating groove of the host.

The above-mentioned embodiments are merely illustrative to illustrate the principles and effects of the present invention, and are not used to limit the present invention. Anyone who is familiar with this technique can modify and change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the rights of the present invention should be listed in the scope of patent application described later.
