Abstract

The utility model discloses a vacuum storage and air suction machine, which comprises an air suction machine casing body, a handle is arranged on the air suction machine casing body, above one switch used for starting and closing a circuit is arranged on the handle, an air exhaust opening is arranged at the upper end of the air suction machine casing body, and an air suction device is arranged in the air suction machine casing body; a cover is arranged at the lower end of the air suction machine casing body; a dust filtration net is arranged at the inner side of the cover; an air-tight cushion is arranged at the lower end of the cover; the cover is embedded in the corresponding air valve. The air-tight cushion is used for increasing the sealing degree of the vacuum storage and air suction machine, the air suction device is started up by utilizing the switch device arranged on the handle, to evacuate the air out of a container, the storage life of the object positioned in the container is ensured to be increased, the vacuum storage and air suction machine also can evacuate the air in the storage bag, therefore reducing the volume of the storage bag with objects, to ensure the functions of the increasing of the storage life and the efficient utilization of space to be achieved.

Description

Vacuum is taken in lift pump

Technical field

The utility model relates to a kind of vacuum and takes in lift pump, the cover mouth that utilizes the lift pump lower end to be provided with cooperates air packing, be embedded at corresponding container air valve and take in the band air valve, can extract the air of container and collecting bag out, make it can increase the pot-life and effectively utilize the space.

Background technology

Vacuum packaging often applied to store methods such as food, medicine, important instrument, disk in the past, it is completely cut off with air fully, increase the pot-life, also often be used in accommodating container or collecting bag in the daily life now, allow general family simply device fabrication go out to level off to the state of vacuum.

Existing collecting bag, often be applied to pack clothes, cotton-wadded quilt or other can be changed the article of shape, by collecting bag can deaeration structure design, the cumulative volume of taking in is dwindled, in order to do being convenient to collection or carrying, the exhaust structure of this collecting bag, normally be provided with a blow off valve at the bag chosen place, utilize the setting of this air valve, be available for users to use dust collecting fan or other aspirator system, the mouthpiece cover of dust collecting fan is located on the blow off valve, to pack air sucking-off in the collecting bag bag of article with this, to reach volume-diminished and to avoid a bag interior air to cause functions such as article go bad, though known blow off valve can engage for the suction pipe of dust collecting fan or special aspirate tube and use, but this suction pipe must the user be handed the aligning blow off valve, and be pressed on the air-breathing function of reaching that blow off valve upper end could be certain, moreover, because of its air suctiton inlet specification difference of different aspirator systems, be not to be applicable to blow off valve, can't reach the state of vacuum when making it to carry out air-breathing operation really, hold defectives such as above-mentioned existing air valve or aspirator system, not enough satisfied user's demand is now demanded further improvement urgently.

The utility model content

The purpose of this utility model is, a kind of aspirator system that aspirator system and air valve can more be fitted tightly is provided, and more can reach the enforcement state of vacuum when air valve and aspirator system are cooperated.

One vacuum is taken in lift pump, comprises; One lift pump housing is provided with handle, and handle is provided with more than one in order to start or to close the switching device of loop circuit, and the upper end is provided with exhausr port, and its inside is provided with aspirator system; Be provided with a cover mouth in described lift pump housing lower end; Be provided with dirt filtrating screen in a described cover mouthful inboard; Also be provided with air packing in a cover mouthful lower end; Above-mentioned cover mouth is embedded at corresponding air valve.

Aforesaid switching device connects source of AC.

Aforesaid switching device connects the portable direct supply.

The utility model compared with prior art has following remarkable advantages and beneficial effect:

A kind of vacuum of the utility model is taken in lift pump, it establishes an aspirator system as for the lift pump enclosure interior, the top is provided with exhausr port, utilize the set cover mouth in lower end, cooperate cooresponding container air valve or collecting bag air valve, make this cover mouth be embedded at corresponding air valve, elastomeric soft materials is had in system because of air packing, so can make cover mouth and corresponding air valve, fit tightly, utilize the switching device that is provided with on the handle to start aspirator system,, block foreign matter with a cover mouthful inboard dirt filtrating screen of installing and enter the lift pump housing the air extraction of internal tank, make the article that are positioned in the container can increase the pot-life, also can dwindle the volume that collecting bag is taken in article by the air of extracting out in the collecting bag, it can be reached increases the pot-life and effectively utilizes function such as space.

The specific embodiment

Below in conjunction with accompanying drawing specific embodiment of the utility model is illustrated:

A kind of vacuum of the utility model is taken in lift pump, sees also as Fig. 1～shown in Figure 4, and keystone configuration comprises lift pump housing 1, aspirator system 2, cover mouthfuls 3, dirt filtrating screen 31 and air packing 32, wherein;

See also as Fig. 1～shown in Figure 4, lift pump housing 1 inside is provided with aspirator system 2, the outside is provided with handle 11, switching device 111 is set on the handle, the upper end is an exhausr port 12, the lower end is provided with cover mouth 3, this cover mouthful 3 inboard installing dirt filtrating screens 31, and air packing 32 is installed in the lower end, see also as shown in Figure 4, to cover the corresponding air valve 5 that mouth 3 is embedded at container or collecting bag 7, because of air packing 32 has elastomeric soft materials, so can make cover mouth 3 and corresponding air valve 5, fit tightly, start aspirator system 2 with switching device 111, container or collecting bag 7 inner airs are extracted out, block foreign matter with a dirt filtrating screen 31 that covers mouth 3 inboard installings and enter lift pump housing 1, via the set exhausr port 12 in lift pump housing 1 upper end with air exhaustion, make internal tank reach the convergence vacuum state, and collecting bag significantly dwindles volume because of outside atmospheric pressure.

Aforesaid switching device 111 promptly can connect source of AC, also can connect the portable direct supply.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
