First, please also refer to Fig. 1 to Fig. 3, Fig. 1 is the schematic diagram that inflator of the present utility model is taken out pressure type breast pump, and Fig. 2 is the decomposition texture schematic diagram of taking out pressure type negative pressure device of the present utility model, and Fig. 3 is the combinative structure schematic diagram of taking out pressure type negative pressure device of the present utility model.Inflator of the present utility model is taken out pressure type negative-pressure breast pump, comprise feeding bottle, connect trachea and take out pressure type negative pressure device, feeding bottle is by connecting trachea 5 and taking out pressure type negative pressure device and be connected, and takes out pressure type negative pressure device and comprises inflator 10, piston stator 11, piston packing 12, back-moving spring 13, shakes hands 14 and handle 15.
For inflator 10, refer to Fig. 4, the structural representation that Fig. 4 is inflator of the present utility model.As shown in Figure 4, inflator 10 of the present utility model is a Hollow barrel, its bottom be connected trachea 5 and be connected, its top is provided with screw thread, thereby is connected with the bottom of handle 15.
For piston stator 11 and piston packing 12, refer to Fig. 5 to Fig. 7, Fig. 5 is the structural representation of piston stator of the present utility model, Fig. 6 is the enlarged diagram of piston stator of the present utility model and handle coupling part, the structural representation that Fig. 7 is piston packing of the present utility model.As shown in Figures 5 to 7, piston stator 11 of the present utility model and piston packing 12 are arranged in inflator 10, and piston packing 12 is sheathed on piston stator 11, and can slide up and down along the inwall of inflator 10.And the top of piston stator 11 is provided with a boss, the bottom outer wall of handle 14 is provided with screw thread, to be fixedly connected with described boss.
Please refer to Fig. 8 and Fig. 9, Fig. 8 is the structural representation of back-moving spring of the present utility model and handle, the structural representation that Fig. 9 is handle of the present utility model.As shown in Figure 8 and Figure 9, back-moving spring 13 of the present utility model is set around the bottom of handle 14, and the lower end of handle 14 is fixed in one end of back-moving spring 13, the other end of back-moving spring 13 is fixed on the upper end of piston stator 11, so as handle 14 and piston stator 11 while being pulled to inflator 10 top pulling force after cancelling, make its return.Handle 15 comprises base 151 and framework 152, and base 151 is threaded with inflator 10, and framework 152 is for the Q-RING that has radian is on one side to meet ergonomics.Handle 14 is T-shaped, it comprise bottom bar 141 and with the perpendicular portion of carrying 142 of bottom bar 141, bottom bar 141 is arranged in base 151 and is fixedly connected with the top of piston stator 11, carries portion 142 and is placed in framework 152 and can in framework 152, moves up and down.
In addition, 14 to be closely connected with piston stator 11 in order making to shake hands, to refer to Fig. 6, Fig. 6 is the enlarged diagram of piston stator of the present utility model and handle coupling part.As shown in Figure 6, the locking oblique triangle tooth 110 that moves back that boss plane layout of the present utility model has annular evenly to arrange, fastens with the outer wall of handle 14, so that screw thread can not screw out and form handle screens 140 after screwing.
In this utility model, as shown in figure 10, feeding bottle comprises breast pump dust cap 1, silicone gel implant cover 2, three-way suction device 3, silica gel gas check valve 7, feeding bottle 8 and base 9, wherein, three-way suction device 3 is provided with threeway seal cover 4 and spiral suction barrier film 6, spiral suction barrier film 6 is positioned at the intermediate connection place of three ports of three-way suction device 3, and spiral suction barrier film 6 is made by silica gel.The first port of three-way suction device 3 is communicated with silicone gel implant cover 2, is arranged with dust cap 1 on brassiere 2; The second port of three-way suction device 3 is provided with silica gel gas check valve 7, and is communicated with feeding bottle 8; The 3rd port of three-way suction device 3 by threeway seal cover 4 be connected trachea 5 and be communicated with.As can be seen here, this utility model by being provided with spiral suction barrier film in threeway, make in the time that breast pump is worked, inflator negative pressure is not to be directly delivered to threeway suction port, but isolate and cushion by spiral suction barrier film, to avoid negative pressure excessive and human body is produced to injury, simultaneously spiral suction barrier film can play again the anti-overflow effect that isolation milk enters trachea.
Thus, with the three-way suction device 3 of spiral suction silica gel 6 by connecting trachea 5 and taking out pressure type negative pressure device and be connected, in the time pulling the handle 14 of taking out pressure type negative pressure device, press raw air negative pressure by piston stator 11 and piston packing 12 in the interior motion of inflator 10, be delivered to three-way suction device 3 by connecting trachea 5, 6 compressions of spiral suction silica gel, after being blocked up, silicone gel implant cover 2 produces suction, piston packing 12 is under handle 14 drives, while once moving to inflator top, a now interior and three port negative pressure maximum, then under the driving of back-moving spring 13, piston packing return, now complete a suction and put circulation.
Therefore, become a mother in the time using inflator of the present utility model to take out pressure type negative-pressure breast pump, one of mother holds the shank of feeding bottle 8, the silicone gel implant cover 2 of the bell mouth shape of feeding bottle is gently pressed on to breast, another holds takes out pressure type negative pressure device handle 15, pull back and shake hands 14 with finger, inflator 10 inner carrier diaphragm seals 11 are to inflator 10 tops, extracting air, negative pressure is just formed on inflator bottom, be delivered to feeding bottle breast pump top airtight chamber by connecting trachea 5, make spiral suction barrier film 6 produce Inward deflection, the silica gel gas check valve 7 of the unidirectional gas circuit in breast pump lower end cuts out, negative pressure reaches the silicone gel implant cover 2 of breast pump threeway bell mouth shape, breast is formed to suction and massage, and by milk sucking-off, when handle 14 is moved to after least significant end, unclamp handle 14, handle 14 is under the driving of the interior back-moving spring 13 of inflator 10, start return, now inflator 10 internal gas pressures slowly disappear, the silica gel gas check valve 7 of the unidirectional gas circuit in feeding bottle extractor lower end is opened, and now accumulates in to have under milk to flow in feeding bottle herein, and one sucks and circulated.
As can be seen here, inflator negative pressure of the present utility model is not to be directly delivered to threeway suction port, but isolate and cushion by spiral suction barrier film, can play like this milk anti-overflow, can play again suction buffering and not hurt sb.'s feelings, in addition, piston packing of the present utility model adopts outer oblique movable sealing means, there is air-tightness good, the advantage that return mechanical resistance is little.
Need statement, above-mentioned utility model content and detailed description of the invention are intended to prove the practical application of technical scheme that this utility model provides, and should not be construed as the restriction to this utility model protection domain.Those skilled in the art are in spirit of the present utility model and principle, when doing various amendments, be equal to and replace or improve.Protection domain of the present utility model is as the criterion with appended claims.
