Description

Simple vacuum storage container

The utility model belongs to a kind of vacuum save set that is used for food fresh keeping or article preservation.

At present people for food fresh keeping and article preserve majority be vacuumize with some easy leak free utensils after, seal again.Its complex structure, the cost height; What have also will consume certain electric energy; Can not repeated usage after the unpacking that has; The degree of vacuum that has is low, and leak tightness is poor, and fresh-keeping effect is not good; More can not spread to family is extensive use of.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of simple vacuum conservator is provided.

The purpose of this utility model is achieved in that

The simple vacuum conservator comprises hand-operating vacuum-pump and vacuum vessel two parts.Hand-operating vacuum-pump is that the criss-cross piston rod is housed in cylinder barrel, and an end of piston rod is installing handle, and the other end is installing the piston of adorning Y shape or U-shaped elastic piston ring in its peripheral groove.Have air extractor vent on the piston, elastomeric conical exhaust plug with the elastic component crimping in the plunger shaft.The cylinder barrel bottom is installing the bottom with air extraction connector, and the elastic pressuring plate that air extractor vent is arranged on it in crimping between its tube bottom end face and the bottom, and elastomeric conical air inlet spool in the middle part crimping of elastic pressuring plate.Installing the end on the air extraction connector of bottom the extraction pipe of bleeding and chewing is being arranged.Bleed to chew and be connected with the closing device of vacuum vessel.

Vacuum vessel is that seal ring and lid are housed on vessel port, and the cylindrical projection of its lid, the middle part is recessed and have air bleeder, and seal ring and lid are fastened on the vessel port with dead ring.Closing device is equipped with at the air bleeder place of lid.Adorning interior cup with the support frame in the container.

Closing device is that the middle part that at one end is the flexible pipe body of sucked type has the ring of flattening, the useful frenulum bonded assembly of other end pipe close.

The piston of hand-operating vacuum-pump is hood-shaped piston, and its piston ring and piston are an integral body.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model simple vacuum conservator scheme drawing;

Fig. 2 is the utility model hand-operating vacuum-pump scheme drawing;

Fig. 3 is the hood-shaped piston scheme drawing of the utility model;

Fig. 4 is the utility model vacuum vessel scheme drawing;

Fig. 5 is the utility model closing device scheme drawing.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

Simple vacuum conservator (Fig. 1) comprises hand-operating vacuum-pump 1 and vacuum vessel 2.The manual vacuum pump structure is as shown in Figure 2: criss-cross piston rod 4 is housed in cylinder barrel 3, and an end of piston rod is installing handle 5, and the other end is installing cylindrical piston 6.Air extractor vent 7 is arranged on the piston, adorning Y shape or U-shaped rubber piston ring 8 in the peripheral groove of piston.The also available elastomeric material of piston ring and piston is made an integral body and is hood-shaped piston (as shown in Figure 3).Conical rubber exhaust plug 10 with elastic component 9 crimping in the plunger shaft.The end of cylinder barrel is installing the bottom 12 that air extraction connector 11 is arranged on it.Compressing the elastic pressuring plate 14 that air extractor vent 13 is arranged on it between the bottom end face of cylinder barrel and the bottom, conical rubber air inlet spool 15 in the middle part crimping of elastic pressuring plate.Its end that is being connected on the air extraction connector has flexibility to bleed to chew 16 extraction pipe 17.The closing device of chewing with vacuum vessel covers of bleeding is connected.

The structure of vacuum vessel is equipped with seal ring 19 and cylindrical projection, the middle part is recessed and there is the lid 21 of air bleeder at 20 places as shown in Figure 4 on the mouth of glass or plastic container 18, its lid and seal ring usefulness dead ring 22 are fastening.The air bleeder place of lid is adorning closing device 23.Cup 25 in adorning with 24 on support in the container, thus container is divided into two-layer so that food or taxonomy of goods preservation.The structure of closing device as shown in Figure 5,27 places, middle part that 26 places are the flexible pipe body of sucked type in the end are provided with flattens ring, the other end of body is provided with the frenulum 29 that there is pipe close 28 its end.Container also can adopt plastic film bag, and at this moment, the end sucker of flexible pipe body can change taper pipe into, directly inserts the interface of sack or the air bleeder place on the bottle cap.

During use, vacuum vessel is rinsed well, sterilized, put into food or article, close the lid, check the sealing state between vessel port and the lid, as good seal, fastening with dead ring.Closing device is inhaled at the air bleeder place that covers, and bleeding of hand-operating vacuum-pump chewed in the mouth of pipe that injects closing device.When bleeding, the pulling handle moves on the piston, the cylinder barrel internal volume increases, pressure reduces, and under the effect of elastic component, exhaust plug closes in plunger shaft, because the vacuum vessel internal gas pressure is greater than the cylinder barrel internal gas pressure, under the difference of pressure effect, the air inlet spool is opened, and the gas in the vacuum vessel enters in the bottom chamber by sealing tube, extraction pipe, air extractor vent from the elastic pressuring plate enters in the cylinder barrel again, and pumping process is finished.During exhaust, driving handle, piston moves down, the cylinder barrel internal volume reduces, and pressure increases, under the effect of pressure reduction and elastic pressuring plate, the air inlet spool closes in the bottom chamber, and the exhaust plug in the plunger shaft is opened, and the gas in the cylinder barrel enters cylinder barrel by the air extractor vent on the piston and enters and beg greatly, and exhaust process is finished.Several times can be extracted the gas in the vacuum vessel out so repeatedly.Bleed finish after, compress the flattening ring that seals on the body with finger, make it temporarily sealing tube to be shut, extract bleeding of vacuum pump and chew, inject pipe close, vacuum is all over.Degree of vacuum in the container can reach 0.85 more than the barometric pressure.Also can take off closing device this moment, and the air bleeder that covers is shut with cured or adhesive agent, puts the preservation of shady and cool ventilation place and get final product.

The utility model compared with prior art has the following advantages:

Simple in structure, easy to use; Reliable operation, the efficient height; Make easily, cost is low; The vacuum height, storage effect is good; Without any need for the energy; Hand-operating vacuum-pump is can a pump multiplex; Vacuum tank can adopt sealing device special, also can utilize used vial, plastic bottle to reach All airtight containers such as its plastic film bag. Can greatly reduce cost of use. Being widely used in tourism, dormitory, family, dining room, restaurant etc. needs food fresh-keeping to store and article protection against the tide, insect protected, antipollution occasion.
