Problems solved by technology

From the description of the patent, we can see that there are only two modes of breast pumping on both sides of the existing double-sided breast pump, one is controlled by a single-sided converter and only one side is sucked, and the other is Turn on both sides to pump, but both sides work simultaneously
This working mode will bring some problems; 1. When a single air pump drives two-way breast pumping at the same time, it will increase the burden on the air pump. Either increase the power of the air pump to increase the cost and noise, or the suction pressure is insufficient; It does not meet the requirements of interval suction to reduce the pressure on the human body, and the use of control circuit interval suction will cause the current impact caused by the frequent start and stop of the air pump motor and also damage the electronic control system to a certain extent

Embodiment 1

[0036] Such as figure 2 As shown, a single-air pump dual-channel breast pump includes an air pump 1, an air circuit steering valve 2, and a pair of feeding bottle assemblies 3. The air pump 1 communicates with the feeding bottle assembly 3 through the air circuit steering valve 2. At the same time, the gas path is switched by the gas path steering valve 2, so that the negative pressure generated by the air pump 1 acts on one of the pair of feeding bottle assemblies 3 to meet the requirements of sucking milk.

[0037] Such as image 3 As shown, the air circuit steering valve 2 includes a negative pressure port 21, a first feeding bottle interface 23, a second feeding bottle interface 25, a driving device 26 and a valve core assembly 27; The first suction air path 28 inside is connected to the negative pressure port 21 to form the first air path; The second gas path: the first gas path is connected in parallel with the second gas path, and the driving device 26 controls the a...

Embodiment 2

[0050] Such as Figure 6 , 7 , 8, a single air pump dual-channel breast pump, the difference between embodiment 2 and embodiment 1 is that the valve core assembly 27 includes a support frame 272, a swing arm frame 277, a swing arm 278 and a pair of plungers The rod 279, the support frame 272 and the swing arm frame 277 are fixedly installed in the air circuit steering valve 2, the middle part of the swing arm 278 is hinged on the swing arm frame 277, and a pair of the plunger rods 279 are symmetrically connected to the swing arm At both ends of 278, the cam 262 drives the swing arm 278 to reciprocate through the driving rod 263; a pair of plunger rods 279 are respectively provided with a valve core 275 matched with the first air path and the second air path; In this embodiment, preferably, the valve core 275 is a two-way sealing ring.

[0051] The present invention can be further described as that, the cam 262 is provided with a guide chute 264 , one end of the driving rod 2...

Abstract

The present invention relates to the field of mother and baby products, in particular to a breast pump. The single-air-pump dual-path breast pump comprises an air path steering valve; the air path steering valve comprises a negative pressure hole, a first milk bottle interface, a second milk bottle interface, a driving device and a valve element assembly; the first milk bottle interface communicates to the negative pressure hole by a first suction air path in the air path steering valve to form a first air path; the second milk bottle interface communicates to the negative pressure hole by a second suction air path in the air path steering valve to form a second air path; the first air path and the second air path are connected in parallel; and the driving device controls the valve elementassembly to act for enabling the air path steering valve to alternately open the first air path or the second air path. The air path steering valve is simultaneously connected with a pair of milk suction bottle assemblies and switches the air path, the single milk suction bottle assembly can be provided with negative pressure alternately under the motor control of the air path steering valve by adopting an air pump, the requirements on the power of the air pump are not extra added, and the comfort demand of alternate milk suction is further met.

Description

technical field [0001] The invention relates to the field of maternal and infant products, in particular to a breast pump. Background technique [0002] An electric breast pump usually consists of a negative pressure source and a feeding bottle assembly. The negative pressure source acts on the feeding bottle assembly by generating negative pressure and simulating the baby's sucking action to achieve milking; this method of sucking milk takes into account the impact on the human body Factors such as impact and pain caused by suction are usually not suitable for continuous operation, so the efficiency of breast pumping on one side is low, and the left and right sides need to be adjusted manually to achieve continuous breast pumping, which not only brings trouble to the user, but also has low efficiency . [0003] Therefore, a kind of bilateral milk-sucking device has also appeared in the prior art, for example: discloses a kind of imitation sucking positive and negative pres...
