Abstract
The utility model relates to a sucking pump used for a vacuum preservation box. The pump is characterized that the pump is provided with a tubular sucking cylinder, a tubular sucking core is arranged in the sucking cylinder, and a sealing ring is mounted at the lower end part of the sucking core; a sucking head made of soft plastic or rubber is sleeved on the circumference at the lower end part of the sucking cylinder, a handle is mounted at the upper end of the sucking core, and a row of air holes are formed on the sucking core near the sealing ring. The sucking pump has the advantages of simple and reasonable structure, reliable sucking performance, and high efficiency, and specially suits the air pumping of the vacuum preservation box.
Description
Technical field
The utility model relates to a kind of air pump, especially relates to a kind of instrument of bleeding.
Background technique
As everyone knows, food is because of making food apoilage with airborne oxygen generation oxidation.A kind of method of food fresh keeping, as draw the food of can drink and so on is that content is added preservative, and carries out sterilizing, sealed storage then, its long shelf-life; Fresh-keeping another kind of method is to adopt vacuum to store.Vacuum crisper in the market is existing multiple.As Chinese patent CN2129743 vacuum crisper, it is made up of container body and lid, covers and is provided with two-way valve and air vent, between lid and the container body Sealing is housed, and it is fresh-keeping to use special tool that the air extraction is reached sealing.The structure more complicated that the extraction pump of prior art has, what have exists some problems aspect reliability.
Summary of the invention
The utility model main purpose is: develop a kind of simple in structurely, reliable performance is applicable to the extraction pump of vacuum crisper.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of extraction pump that is used for vacuum crisper, it is characterized in that: have the tubulose pump bowl, the tubulose core of bleeding is arranged in the described pump bowl, and seal ring is equipped with in the underpart of the core of bleeding; Be with the head of bleeding that adopts soft plastic or rubber to make on the circumference of the underpart of described pump bowl, handle is equipped with in the upper end of the core of bleeding, and the core of bleeding has an exhaust port near the seal ring place.
Therefore, the beneficial effects of the utility model are: simple and reasonable for structure, pumping performance is reliable, the efficient height, and the air that is specially adapted to vacuum crisper aspirates.
Description of drawings
Accompanying drawing 1 is a kind of structural upright schematic representation of the present utility model;
Accompanying drawing 2 is structure split figure of Fig. 1;
Accompanying drawing 3 is sectional views of Fig. 1.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Extraction pump as shown in Figure 1-Figure 3 has tubulose pump bowl 4, and the tubulose core 3 of bleeding is arranged in the tubulose pump bowl, and the underpart of the core of bleeding is set with seal ring 6; The upper end that the core of bleeding is positioned at seal ring has an exhaust port 31, and handle 5 is equipped with in the upper end of the core 3 of bleeding; Be with on the circumference of the underpart of tubulose pump bowl adopt that soft plastic makes bleed 1, handle 5 is equipped with in the upper end of the core 3 of bleeding, the core of bleeding is threaded with the handle employing.
The utility model in use, with 1 check-valve port of aiming at the vacuum crisper of having built lid of bleeding (bleed 1 diameter more bigger) than check-valve port, when the core 3 of bleeding upwards promotes, check-valve port is opened, air in the box is extracted out from valve port, when the core 3 of bleeding is pushed downwards, the check-valve port sealing, the gas in the pump bowl is discharged by exhaust port 31.So repeatedly repeat, reach the purpose that air is constantly reduced in the vacuum crisper.
