The specific embodiment
Counterflow-preventing adapter as shown in Fig. 1 ~ 3, comprise upper shell 1, elastic covering 2 and lower house 3, one end of upper shell 1 is the first opening 11, on the upper shell 1 relative with this first opening 11, extend outward the first tube-shaped joint 12, elastic covering 2 seal closures are located at the first opening 11, this elastic covering 2 encloses and forms suction chamber 4 with upper shell 1, one end of lower house 3 is the second opening 31, the periphery and the elastic covering 2 that on the lower house 3 relative with this second opening 31, extend outward the second tube-shaped joint 32, the second openings 31 are tightly connected.
After the first tube-shaped joint 12 is subject to as the intermittent suction force of breast pump air extractor, this suction force will act on elastic covering 2, cause elastic covering 2 to do the intermitten that shrinks and open.This intermitten of elastic covering 2 by and 3 of lower houses form the negative pressure of intermittences, through the second tube-shaped joint 32 outputs, form again the suction force of intermittence, thereby the suction force of outside air extractor is conducted to the second tube-shaped joint 32, outside as the liquid of milk for aspirating.And when liquid countercurrent to the second tube-shaped joint 32 is interior, because the first elastic covering 2 seal closures are on the first opening 11, liquid cannot enter the first tube-shaped joint 12, realize counterflow-preventing.Wherein, first tube-shaped joint 12 of the present embodiment stretches out towards the oblique upper of upper shell 1, is convenient to be connected with external pipe, prevents the crooked obstruction of external pipe.The second tube-shaped joint 32 can insert in exterior tubular body.As shown in Fig. 2 ~ 3, on the basis of sealing effectiveness that strengthens the first elastic covering 2 and upper shell 1, for the ease of assembling, the periphery of the first opening 11 is extended with spaced the first leg 13 and the second leg 14 downwards, the second leg 14 is positioned at the first leg 13 peripheries, between the first leg 13 and the second leg 14, form slot 5, the periphery of elastic covering 2 is provided with cartridge part 23, and this cartridge part 23 is inserted in this slot 5.
The bottom land of slot 5 is extended with location convex tendon 15 to the notch direction of slot 5, accordingly, has the locating slot 231 inserting for location convex tendon 15 on cartridge part 23.Location convex tendon 15 inserts after locating slot 231, can avoid driving because of the distortion of elastic covering 2 cartridge part 23 to depart from slot 5, has strengthened stable the be connected effect of elastic covering 2 with upper shell 1.
As shown in Figure 3, the periphery of lower house 3 is protruding Access Division 33, accordingly, has the buckling groove 232 for Access Division 33 clampings on cartridge part 23, and Access Division 33 is connected to the mode in buckling groove 232, greatly facilitates the assembling of lower house 3 and elastic covering 2.During assembling, clamping by Access Division 33 with buckling groove 232, first that elastic covering 2 peripheries and lower house 3 sealings are fixing, the cover body of elastic covering 2 is fitted in lower house 3, again the cartridge part of elastic covering 2 23 is inserted to the slot 5 of upper shell 1, make the periphery of elastic covering 2 and upper shell sealing fixing.
The sidewall that the first leg 13 is positioned at slot 5 one sides comprises upper wall 131 and the lower wall 132 that is connected in these upper wall 131 lower ends, upper wall 131 and elastic covering 2 sealing laminatings, and lower wall 132 and elastic covering 2 are separately.Lower wall 132 provides spatial accommodation with the distortion that is spaced apart cartridge part 23 that elastic covering 2 forms, and prevents the distortion of cartridge part 23 and departs from slot 5.
The middle part of lower house 3 forms the portion's of arching upward 34, the second tube-shaped joints 32 along the second opening 31 and is connected with this portion 34 that arches upward towards arching upward.The shape that the bootable elastic covering 2 of portion 34 that arches upward shrinks, stablizes to control the deflection of elastic covering 2, and then makes suction force stable.Correspondingly, elastic covering 2 is also arranged to the region of arching upward of mating with the portion that arches upward 34 of this lower house 3, better strengthens the elasticity of elastic covering 2.
Above-mentioned embodiment is only preferred implementation of the present utility model; can not limit with this scope of this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to this utility model scope required for protection.
