Description

Safety device for electric breast pump

The invention is a safety device for an electric breast pump, in particular a safety device having a safety sensing device for detecting a real-time signal when the milk is returned to ensure the safe use of the host. Background technique

As we all know, breast milk is the most natural and most suitable for newborns, and it is also a precious food that cannot be replaced by formula. Breastfeeding not only provides enough antibodies for babies, but for mothers, breastfeeding can also reduce the risk of cancer and enhance parent-child emotions. In addition to the mother's breast feeding, the breast milk feeding method can also be used to pre-empt the milk for storage at the time of breast expansion or non-feeding time.

The existing breast pump products can be mainly divided into electric and manual types. Please refer to FIG. 1, which shows a structural form of a conventional electric breast pump.

As shown in the figure, the structure of the electric breast pump mainly includes a main body 10, a cup holder 20, and a bottle 30, etc., wherein the main body 10 is provided with an operation switch on the surface thereof, and a power motor is internally provided to drive the compression pump. And, the control loop is used to control the time and pressure mode of the pump action (since the internal structure of the host 10 is not the focus of the discussion in this case, so it will not be described here); the front end of the cup holder 20 is provided with a cup 21, and the rear end is pivotally connected to a soft The tube 22, the other end of the hose 22 communicates with the suction end of the compression pump of the main machine 10, and when the main body 10 drives the motor to drive the compression pump, the cup 22 can be used to generate a predetermined suction force through the hose 22; The bottle 30 is a bottle similar to a bottle and can be engaged with the lower edge of the cup holder 20. In this way, the user can hold the bottle 30, align the cup 21 of the cup holder 20 with the picking position of the breast, and then suck the milk through the suction force generated by the main body 10 through the hose 22 and the cup 21, and let the milk pass through the cup holder. 20 flows to the collection bottle 30 for storage. The structure of the above-mentioned existing breast pump and the method of using the same, although it has been used by the user for a long time, there is an objective defect that needs to be improved. Usually, the average user takes about ten to several tens of minutes to suck the milk. On the way, there are often things that happen and the milk is interrupted (for example: baby crying, phone ringing, etc.). The user is hurriedly put down the bottle 30 in the hand and left the seat. Since the cup holder 20 above the bottle 30 is heavier, the bottle 30 will be dumped in the case of poor balance, resulting in the milk possibly along the hose 22. The flow back to the host 10 causes the host 10 to malfunction or short-circuit to burn. In view of this, it is urgent to optimize the design of the existing design of the existing breast pump to effectively improve the practical value and reliability of the product.
