Abstract
A simple and easy concave nipple suction device comprises a cylinder body and a plunger rod. The plunger rod is led in the cylinder body by means of longitudinal shifting. The diameter of at least one end port of the cylinder body is from 3 centimeters to 5 centimeters. The simple and easy concave nipple suction device has the advantages of being simple in structure, convenient to operate and not prone to damaging a nipple.
Description
Technical field
This utility model relates to a kind of simple and easy depression nipple suction pump.
Background technology
The captivation of the large generation of existing nipple aspirator volume is larger, the easy damaged nipple, and inconvenient operation attracts effect section desirable simultaneously.
Summary of the invention
The purpose of utility model provides the depression nipple suction pump of a kind of simple in structure, convenient operation, non-easy damaged nipple.
The purpose of this utility model is achieved in that a kind of simple and easy depression nipple suction pump, comprise cylindrical body, plunger rod, but this plunger rod is guided in described cylindrical body by the mode with vertical shift, and at least one end port diameter of cylindrical body is 3-5CM.
All right, the port edge place is provided with foam-rubber cushion.
The advantage of this full mold is: be the port alignment recess nipple of 3-5CM with diameter with cylindrical body, then in cylindrical body, form negative pressure at cylindrical body vertical shift plunger rod, utilize negative pressure to recover the nipple raised position, because at least one end port diameter of cylindrical body is 3-5CM, its volume is little, form negative pressure also little, only just pull out depression nipple, not the easy damaged nipple; Port diameter is that 3-5CM edge is provided with the damage that foam-rubber cushion can prevent from causing at negative pressure state lower port edge nipple.
Description of drawings
Below in conjunction with drawings and Examples invention is described further.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, suction pump comprises cylindrical body 1, plunger rod 2, but this plunger rod 2 guided in described cylindrical body 1 by the mode with vertical shift, cylindrical body 1 at least one end port 3 diameters are 3-5CM; Port 3 edges are provided with foam-rubber cushion 4.
Operation principle: be that 3-5CM is that port 3 is aimed at accurate depression nipples with cylindrical body 1 diameter; at cylindrical body 1 vertical shift plunger rod 2 in cylindrical body 1 interior formation negative pressure; recover the nipple raised position under the effect of negative pressure, foam-rubber cushion 4 can protect port 3 edges not cause the damage of nipple under negative pressure state.
Claims (2)
1. simple and easy depression nipple suction pump, it is characterized in that: described suction pump comprises cylindrical body (1), plunger rod (2), this plunger rod (2) but guided in described cylindrical body (1) by the mode with vertical shift, at least one end port of described cylindrical body (1) (3) diameter is 3-5CM.
