Abstract

The utility model relates to a tea and food preserving pot for keeping vacuum degree, and which comprises a pot body and a pot cover; the utility model is characterized in that a sealing ring is arranged on the joint of the pot body and the pot cover; a vacuum-pumping device which comprises a vacuum pump, a motor and a motor controlled circuit is arranged in the pot base of the bottom of the pot body according to the pot body. The utility model can keep dryness and certain vacuum degree in the pot, and avoid the moist and metamorphism of the goods to be stored, especially has perfect tea preserving effect. The utility model has the advantages of simple structure and convenient implementation, which can be used for various tea pots and food pots with different specifications and shapes, as well as the daily storage ware for tea in ordinary families, meanwhile, the utility model can be used as the tea packaging during the sales process, so that the preserving quality can be improved and the storage period can be prolonged.

Description

Tealeaves, the food fresh keeping jar that can keep degree of vacuum

Technical field:

The utility model relates to the utensil of depositing tealeaves, food.

Background technology:

Tealeaves and food fresh-keeping largely depended on the humidity and the oxygen content of its storage environment, and making moist to make it rotten mouldy.And for tealeaves, avoiding oxidation is fresh-keeping important means.Tealeaves has the vast consumer group in China, but the fresh-keeping of tealeaves all the time can not be satisfactory.There is not a kind of tea can remain a jar interior degree of vacuum.

Summary of the invention:

Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology weak point, and a kind of tealeaves, food fresh keeping jar that keeps degree of vacuum is provided.

The technical scheme that the utility model technical solution problem is adopted is:

The utility model is made of tank body and cover.

Constructional feature of the present utility model is:

Binding site at described tank body and cover is provided with seal ring;

At tank body vacuum device is set, comprises that the vacuum device of vacuum pump, motor and control path is positioned at the fangs of tank base.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model is improved the sealing property of tea can by between tank body and cover hermetically-sealed construction being set, thereby keeps a jar interior drying, and the article of avoiding being stored become damp and rotten.

2, the utility model makes tank body have certain degree of vacuum by tank body is provided with vacuum extractor, avoids oxidation, especially tealeaves is had good fresh-keeping effect.

3, the utility model is simple in structure, easy to implement, and its relevant version can be applied on different size, difform various tea cans, the food cans.

4, the utility model can also can be used as the tea packaging in the sales process as the daily storing utensil of tealeaves in average family, can improve the fresh-keeping quality of product, prolongs the freshness date of product.

Fig. 1 is the utility model structural representation.

Fig. 2 is this practical control schematic circuit diagram.

The specific embodiment:

Referring to Fig. 1, present embodiment is made of tank body 1 and cover 2, at the binding site of tank body 1 and cover 2 seal ring 3 is set.Shown in the figure, vacuum device is set, comprises that the vacuum device of vacuum pump 4, motor 5 and electric machine control circuit 6 is positioned at the fangs 7 of tank base at tank body 2.

In order can conveniently to open, on cover 2, offer pore, manual air valve 8 is set in the pore.During opening, mention the manual button of manual air valve 8, then air valve is opened, and in the air admission jar, the tank body inner and outer air pressure reaches balance, and cover can normally be opened.

In order to make its good looking appearance, can adopt double-canopyly, promptly in the outside of cover 2, other has an enclosing cover 10.

Referring to Fig. 2, in the present embodiment, adopt the vacuum manometer 9 of band contact, the electric machine control circuit is that the break-make with the contact of vacuum manometer 9 is motor start and stop control signals.Its working process is specially: the energized K switch, 220 volts of alternating-current voltage/AC voltages provide working power for control path after capacitor C 1 step-down, D1-D4 rectification, capacitor C 2 filtering.Collecting electrode at aerotron BG1 is provided with the execution relay J, between the base stage and power supply positive and negative electrode that two winding point JY1 of vacuum manometer and JY2 are separately positioned on aerotron BG1, and have the open contact J1-2 of relay J to be arranged in parallel as self holding contact and contact JY1, another of relay J often open touching the series connection be arranged in the electric power loop of motor M.

Degree of vacuum does not reach setting value in jar, and compression indicator contact JY1 is an on-state, at this moment, aerotron BG1 conducting, relay J gets electric, and motor M starts, and motor internally carries out vacuum pumping by vacuum pump; Meanwhile, because the contact J1-2 conducting of relay J is kept the base stage positive voltage signal of aerotron BG1.In case degree of vacuum reaches setting value, compression indicator contact JY2 is switched on, aerotron BG1 thereby be cut off, and the relay J dead electricity, motor M quits work.After this, the degree of vacuum in jar reaches setting, but also begins As time goes on and gradually to descend, and when dropping to the minimal pressure setting value, motor is activated again, so circulation, thus the degree of vacuum in the jar is remained in certain number range.

Claims
