Abstract
The utility model relates to a vacuum fresh-keeping box by utilizing vacuum to preserve articles, which is formed by that evacuating equipment is sealed and connected with a fresh-keeping box body, wherein, the evacuating equipment is provided with a gas cylinder (5), a piston (6) is arranged inside the gas cylinder (5), the middle part of the piston (6) is provided with a circle of rectangular grooves, sealing rings are arranged inside the grooves, and small holes (12) which are communicated with the gas cylinder (5) are arranged at the bottom of the grooves. The piston (6) slides up and down inside the gas cylinder (5) by pumping pressure. Gas inside the fresh-keeping box body (10) enters the gas cylinder (5) through the small holes (12) and is exhausted from the top part. The fresh-keeping box body (10) is pumped into vacuum by pumping the pressure repeatedly to attain fresh keeping of the articles inside the box.
Description
The utility model relates to the vacuum freshness retaining technical field, specifically will be evacuated in the box, prolongs the holding time of food or medicine.
Present vast rural town of China and outlying mountain area, the popularity rate of household electric refrigerator is also very low, and along with reform, open, people's living standard is in continuous improve, and some food, medicine etc. need to preserve a period of time.
The purpose of this utility model provides vacuum crisper a kind of simple in structure, easy to use.
The purpose of this utility model is achieved in that in fresh-keeping body (10) upper end air extractor is set, in its device, be provided with piston (6) in the inflator (5), the air in the fresh-keeping box body (10) extracted out, food and medicine are in the vacuum preserve by the upper and lower slip of piston (6).
The utility model has the advantages that simple in structurely, need not power, be easy to popularize that general family all can use.
Description of drawings
Accompanying drawing 1 is the vacuum crisper structural representation;
Fundamental diagram when accompanying drawing 2 presses down handgrip for air extractor;
Fundamental diagram when accompanying drawing 3 is air extractor extracting handgrip.
Among the figure: (1) handgrip; (2) ball core non-return valve; (3) loam cake; (4) piston rod; (5) inflator; (6) piston; (7) " Y " RunddichtringO; (8) unidirectional needle valve; (9) fresh-keeping lid; (10) fresh-keeping box body; (12) aperture; (11) (15) (13) (14) sealing ring; → airflow direction.
Below in conjunction with drawings and Examples the technical solution of the utility model is described in further detail.
Form by air extractor and fresh-keeping box body (10) referring to accompanying drawing 1, vacuum crisper: at the neck of fresh-keeping box body (10) loam cake (9), thread seal connects the lower end of air extractor inflator (5), in the middle of the junction unidirectional needle valve (8) is set, to gas can only outwards be extracted out.Referring to accompanying drawing 1, be provided with the piston (6) that the middle part has a circle square type groove in the inflator of air extractor (5), the lower end of its bottom portion of groove has the aperture (12) that communicates with inflator (5); Piston (6) center fixation connects piston rod (4), and piston rod (4) upper end is provided with handgrip (1).Referring to accompanying drawing 1, accompanying drawing 2 in the square type groove at piston (6) middle part, is equipped with " Y " RunddichtringO (7), and the groove width of its highly little what square type groove is communicated with inflator (5) so that expose aperture (12).
Referring to accompanying drawing 1, on the loam cake (3) on inflator (5) top, be provided with ball core non-return valve (2), to air can only unidirectionally be extracted out.
Accompanying drawing 2, accompanying drawing 3, showed operation principle of the present utility model: upwards twitch piston (6), the volume of inflator (5) bottom increases, air pressure reduces, gas in the fresh-keeping box body (10) enters inflator (5) bottom by unidirectional needle valve (8), locates the upper end of what inflator (5) up to piston (6).When pressing down handgrip (1)) time, ball core non-return valve (2) is closed, piston (6) is to lower slider, " Y " RunddichtringO then in piston (6) groove to top offset until contacting with groove top, expose bottom aperture (12), again with piston (6) synchronously to lower slider, at this moment, inflator (5) lining piston (6) lower space reduces gradually, and gas is compressed, the outer rim of air communication small holes (12) extruding " Y " RunddichtringO enters inflator (5) top.Upwards twitch piston (6) and back down ball core non-return valve (2), gas is discharged, and as mentioned above, takes out repeatedly and presses piston (6), is evacuated in fresh-keeping box body (10).
Air extractor described in the utility model is also applicable to other containers.
Claims (4)
1, a kind of vacuum crisper that utilizes vacuum to preserve article, form by air extractor, fresh-keeping box body, it is characterized in that: be provided with piston (6) in the inflator of air extractor (5), its middle part has a circle square type groove, groove is built-in with " Y " RunddichtringO, and bottom land has the aperture (12) that communicates with inflator (5); Air extractor and fresh-keeping box body (10) are tightly connected.
2, vacuum crisper according to claim 1 is characterized in that: " Y " RunddichtringO that is provided with in the one circle square type groove of piston (6) middle part, the groove width of its highly little what square type groove.
