Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment:
As shown in Fig. 1 to 7, the easy double end breast pump of one provided by the invention, comprise breast pump (not shown), with housing 1 and the circuit main board 2 that is fixed in housing 1 of upper cover 9, main suction pipe 3, air pump cover 4, upper cover 9 is provided with knob 8, housing 1 is also provided with DC socket 42, this DC socket is connected with circuit main board 2 line, air pump cover 4 internal fixtion has air pump 10, described air pump 10 is connected with circuit main board by lead-in wire, signal is sent by circuit main board, main suction pipe 3 is connected with air pump 10 pipeline, described main suction pipe mouth of pipe place is connected with the first branch road suction pipe 5 and the second branch road suction pipe 6 be interconnected, the first described branch road suction pipe 5, second branch road suction pipe 6 is all connected with breast pump, the second described branch road suction pipe 6 is provided with electromagnetic valve 7 with main suction pipe 3 junction, this electromagnetic valve 7 is connected with circuit main board 2 by lead-in wire, described housing 1 is provided with the touch switch 11 of actuating mechanism 12 and Controlling solenoid valve unlatching or closedown, actuating mechanism 12 is arranged on breast pump and the second branch road suction pipe 6 connector place, the end face of touch structure 12 is arranged in the mouth of pipe of the second branch road suction pipe 6, conveniently be used in housing 1 lower end and power storehouse 30 is set, and coordinate fixing with housing 1 by power supply lid 13, in order to reduce the vibrations of air pump 10, between air pump cover 4 and housing, screw column cushion pad 41 is installed, and in order to the vibrations that reduce whole machine and stability, be distributed with cushion pad 14 in power supply lid 13 lower end.
Described actuating mechanism 12 comprises rotation center hold 22, first contact block 21 and the second contact block 20, on above-mentioned housing, 1 is provided with projection 23, rotation center hold 22 is arranged on clearance fit on projection 23, first contact block 21 is conflicted with above-mentioned touch switch 11, second contact block 20 its be positioned at the exit of the second branch road suction pipe 6, second contact block 20 is conflicted with the connection tube of breast pump and the second branch road suction pipe, this set is mainly in order to conflict with the second contact block 20 when allowing the connection tube of breast pump insert, second contact block 20 is squeezed will toward interior movement, the first contact block 21 in actuating mechanism 12 can make to allow the first contact block 21 touch the unlatching of touch switch 11 around projection 23 rotation according to rotation center hold 22, touch switch 11 can this signal feedback on circuit main board 2, make opening of electromagnetic valve, second branch road suction pipe 6 is started working, otherwise when extracting connection tube, second contact block is not squeezed, at this moment first contact block can not touch the unlatching of touch switch, electromagnetic valve does not work.
Preferably, the first described branch road suction pipe is provided with gas bleeder valve 15.
Implementation for a kind of easy double end breast pump is described further: machine only needs an air pump 10, from an air pump 10 out main suction pipe in road, directly lead to outside machine, this road is called the first branch road suction pipe, then at machine intimate, this road suction pipe has individual bifurcated suction pipe, bifurcated suction pipe connects an electromagnetic valve 7, this electromagnetic valve 7 is controlled to open and close by circuit main board 2, and electromagnetic valve 7 connects a road suction pipe again to outside machine, and this road is called the second branch road suction pipe 6.From shape and function, this breast pump can control single head by control panel and inhale or double end suction, and do not need manual operation, convenient in operation, the breast pump than two pumps on cost is low.
Obtain concrete implementation for above-mentioned be: when needing single head to work, electromagnetic valve 7 is in closure state, and the second road branch road suction pipe 6 is obstructed, only have the first branch road suction pipe 5 in work, realize the function that single head is inhaled.When needing double end to work, electromagnetic valve is in logical state, and the second branch road suction pipe 6 also can unobstructed air-breathing, realizes the function that double end is inhaled.
There is such a case in above-mentioned this mode of double end work, namely when user uses single head to inhale, when only inserting first via branch road suction pipe, if but the double end of pattern being arranged to of mistake is inhaled the while of user, because the second branch road channel of suction pipe is also logical under the control of electromagnetic valve, gas leakage will be caused and make to draw.
In order to avoid the problem condition that this is above-mentioned, add touch switch 12 at the second branch road suction pipe mouth place, only have the connection tube when the second branch road suction pipe mouth place insertion breast pump to trigger touch switch 12, machine just can carry out the action of double end suction.If the second branch road suction pipe does not insert suction pipe, because touch switch 12 does not trigger, inhale even if user is arranged to double end, electromagnetic valve also can not carry out the action of leading to, thus avoid gas leak phenomenon.
For general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; its framework form can be flexible and changeable, just makes some simple deduction or replace, all should be considered as belonging to the scope of patent protection that claims of being submitted to by the present invention are determined.
