Abstract

The utility model provides a sealing storing device, comprises a container with a sealing cover which can be open and sealed and with an opening. The wall or the sealing cover (2) of the container (1) is provided with a sealing switch opening (3) and is connected with a sealing flowing switch valve (4) and a drawing air bulge (6) of an injector (5). The injector draws the air out of the storing device or injects the needed air into the needed condition of closing the flowing switch valve and blocks the needed condition into the storing device. The storing device comprises a hard container or a soft plastic bag. The sealing storing device has convenient structure, the energy is not needed, and the sealing storing device is suitable to family, ensuring quality in travel vacuum, and teaching tools which can be played.

Description

Bootstrap reservoir

Affiliated technical field

The utility model relates to a kind of bootstrap reservoir, belongs to a kind of vacuum storage facilities.

Background technology

Commercially available inflater type vacuum can be made strong vacuum, and Motorized vacuum machine than before is light a lot, and cost is more expensive, light not enough unfortunately.A kind of structure of market demand is lighter and handier, in addition with singlehanded just can control use holder more.

The utility model content

In order to overcome existing technical matters, the utility model provides a kind of simplicity of design, and structure is light, and manageable bootstrap reservoir carries for family's storing or travelling.

The technical solution of the utility model is:

The utility model provides a kind of bootstrap reservoir, comprise one and have the container that can open with air tight seal cover cap or opening, (2) have an air tight switch mouth (3) and are connected with the pump drainage gas projection (6) of a syringe (5) through an air tight fluid switching valve (4) on the wall of this container (1) or on the seal cover cap.This syringe closing of fluid switching valve when reaching required state the air extraction in the holder or with the desired gas injection is trapped in required state in the described holder.

This fluid switching valve is made up of spring tube and a clip of containing tube chamber in one.When this clip was opened, the tube chamber of this spring tube opened and makes fluid flow through; When this clamp, fluid is blocked.Spring tube is selected from India rubber tube, silicone tube, or plastic pipe.

This fluid switching valve also can be made up of a rigid rotary switch valve.

This bootstrap reservoir bag can be made up of rigid typing container or soft plastic bag.

This product is light simple and direct easy to control, energy requirement not, and cost is low, and market is wide, but is suitable for lunch box, family vacuum freshness retaining chamber, pocket travelling container for storing milk, the high pressure fragrance system of smoking, send out filial piety device, child's teaching aid toy etc.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1. be embodiment 1.5 of the present utility model

Fig. 2. be embodiment 2 of the present utility model

Fig. 3. be embodiment 3 of the present utility model

The specific embodiment

Embodiment 1. as shown in Figure 1, a kind of singlehanded controollable bootstrap reservoir, (2) have a diameter to be about the hole sample switch mouth (3) of 1mm on the seal cover cap of a 500ml container (1), overlapping an India rubber tube (4a) on it, the other end of this India rubber tube is overlapping the pump drainage gas projection (5) of the syringe (6) of a volume 10ml.Air extraction in the syringe holder holder or desired gas injected when reaching required state clamps India rubber tube with clip (4aa), blocks the fluid passage, and required state is trapped in the described holder.

Embodiment 2. is as Fig. 2. shown in, at one 1, (2) have a diameter to be about the hole sample switch mouth (3) of 0.6mm on the seal cover cap of 000ml container (1), and by an air tight rubber flap valve (4b), the edge is pressed on the outside face of seal cover cap on it; Pump drainage air pressure horn shape projection (5) with the syringe (6) of a volume 20ml is pressed on the seal cover cap of container; During air extraction in the syringe holder holder, the rubber flap valve is smoked, open bore sample switch mouth; Bleed when stopping, the suction force of tubaeform projection also descends, and the rubber flap valve is sucked back by the vacuum in the container, and elasticity is also restored, and presses off above-mentioned hole sample switch mouth again, the block fluid passage.

Embodiment 3. comprises a vacuum reservoir bag (1) as shown in Figure 3, extracts the interior air of reservoir bag, turning handle, off switch valve (4c) out with syringe (6).Also can directly press off the airtight line that reservoir bag opening (2) is located.

This rigid rotary type fluid switching valve, its connection and use comprise:

A) one straight through being the rigid stator of 1cm, wherein pericardium contains a ball-and-socket shape cavity and opens to its right flank, the tubular cavity that this ball-and-socket shape cavity stretches out two diameter 1mm is respectively to the outside face of its upper and lower;

B) one and the rigid spheroid rotor that a) has turning handle accordingly are inserted into this ball-and-socket shape cavity and rotate in this ball-and-socket shape cavity and airtight through its handle through the open surface of above-mentioned ball-and-socket shape cavity; A tubular cavity that equates bore with the tubular cavity of main body is arranged on the line of centers of this spheroid;

C) can pass through at above-mentioned spheroid rotor rotation fluid when the tubular cavity of its tubular cavity and above-mentioned rigid stator is unified into straight line, turn to its tubular cavity fluid impassabitity when not communicating with the tubular cavity of this rigid stator at this ball-and-socket body.

The length of two tubular cavities of the tubular cavity of this ball-and-socket body and this main body is respectively about the 1/5-3/5 of said stator respective length, as 3mm, and 4mm, 3mm.

Embodiment 4. storing stacte jars: vacuum or high pressure all can quicken the infiltration of fragrance and reduce and pollute.Spices is put in the bottom of fumigator, and food is put on top.

Claims

1. bootstrap reservoir, comprise one and have the container that can open with air tight seal cover cap or opening, it is characterized in that on the wall of described container (1) or on the seal cover cap (2) an air tight switch mouth (3) arranged and be connected with the pump drainage gas projection (6) of a syringe (5) through an air tight fluid switching valve (1).
