Description

Electronic extraction pump

Technical field:

The utility model relates to the air-extractor technical field, refers in particular to a kind of electronic extraction pump that vacuum packaging is bled that is used for.

Background technique:

Vacuum freshness retaining is a kind of common methods of preserving food at present, as can, and packings such as part delicatessen and part hot pickled mustard tube.Final vacuum promptly lost efficacy but this on the market packing is unlatching, and not reproducible use is unfavorable for that family promotes the use of; People begin that invention can vacuumize and can reusable vacuum tanks subsequently, and the extraction pump that the coupling vacuum tank uses also produces thereupon.In the technology, being used for mostly being manually operated type to the extraction pump that vacuum tank is bled now, using comparatively time-consuming, effort, is not very easily the people concerning some healths, just is difficult to finish; For some electrodynamic type extraction pumps complex structure then, the bodily form is bigger, still has the place of inconvenience in the use.

Summary of the invention:

The purpose of this utility model is to provide a kind of and is bled by motor driving, and has automatic control to stop the extraction pump of effect.

The utility model purpose again provides a kind of designs simplification, and is easy to use, the electronic extraction pump of good airproof performance.

The another purpose of the utility model provides a kind of electronic extraction pump that visual performance is pointed out the situation of bleeding that has.

For achieving the above object, electronic extraction pump described in the utility model mainly comprises housing and is installed on the interior extraction pump of housing, be configured with pumping chamber in the housing bottom, be provided with pore in the pumping chamber and be communicated with the suction port of extraction pump, extraction pump is bled by a motor driving; One control panel is controlled the startup of motor and is closed, and motor and control panel are installed in the housing.Also draw a tutorial light that can show the situation of bleeding on the control panel, tutorial light is placed on the housing.

Port periphery in pumping chamber is provided with O-ring seal, and working plane is close in O-ring seal during work.

Described housing is by base, center and loam cake stack combinations structure; And be provided with one in the side of base and give the pressure-relief valve of pumping chamber release.

Described extraction pump is an oscillatory type, and the suction port of extraction pump is extended by a valve and inserted corresponding pore in the pumping chamber, between the inwall of the outer wall of valve and pore seal ring seal is arranged.

After adopting said structure, the utlity model has following advantage: 1, motor driving is bled, and saves time, laborsaving; 2, the control panel monitoring is bled, and has the automatic control effect, stopping automatically after not only realization is bled and finished, and the oneself stops in the time of also can realizing bad bleeding, and avoids idle situation of bleeding; 3, be furnished with the tutorial light that shows the situation of bleeding, reach the effect of visual cues; 4, the bodily form is small and exquisite, carries, easy to use.

Embodiment:

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

See shown in the accompanying drawing 1～5, electronic extraction pump described in the utility model mainly comprises housing 1 and is installed on extraction pump 2 in the housing 1, is configured with pumping chamber 11 in housing 1 bottom, be provided with pore 12 in the pumping chamber 11 and be communicated with the suction port 21 of extraction pump 2, extraction pump 2 is driven by a motor 3 and bleeds; Control panel 4 is controlled the startup of motors 3 and is closed, and motor 3 and control panel 4 are installed in the housing 1.Also draw a tutorial light 41 that can show the situation of bleeding on the control panel 4, tutorial light 41 is placed on the housing 1.

Housing 1 is by base 13, center 14 and loam cake 15 stack combinations structure, and base 13 is used to construct pumping chamber 11 and installs and fixes for extraction pump 2 and motor 3, and center 14 has the effect of parcel protection motor 3 evaginations part.The side of base 13 is provided with one and gives the pressure-relief valve 16 of pumping chamber 11 releases, and opening pressure-relief valve 16 can be in communication with the outside pumping chamber 11, thereby eliminates the vacuum state in the pumping chamber 11, and pressure-relief valve 16 is a push type in the present embodiment, and is easy and simple to handle.Loam cake 15 is covered on center 14 upper ends, has the decoration effect, increases entire pump body profile level aesthetic feeling, obtains smooth profile; In the present embodiment, tutorial light 41 is installed in the top of loam cake 15, is easy to observation.

Port periphery at pumping chamber 11 is provided with O-ring seal 17, working plane is close in O-ring seal 17 during work, can guarantee that like this pumping chamber 11 is hedged off from the outer world when work, prevents that outside air from entering in the pumping chamber 11, sealing is good, so that improves pumping efficiency.Behind the bleeding point of the port of pumping chamber 11 butt joint container, starting electrical machinery 3 drives extraction pumps 2 and bleeds, the air of the suction port 21 of extraction pump 2 in pumping chamber 11 aspiration container, and discharge through the relief opening 24 of extraction pump 2, thereby realize the container vacuum suction.Motor 3 drives to bleed and replaces manually bleeding, and both saves time, and is laborsaving again, and easy and simple to handle.

Motor 3 is by control panel 4 controls, and control panel 4 can come automatic control motor 3 work according to the electric current of sampling motor 3.When bleeding startup, the tutorial light 41 luminous demonstrations work of bleeding, along with the gas in the container constantly is drawn out of, air pressure progressively reduces, and the operating load of motor 3 is corresponding to be reduced (can judge by size of current), when gas exhausts, the operating load of motor 3 is relatively stable and no longer change, at this moment control panel 4 detects data and luminous by sending 41 variations of instruction driving tutorial light after the digital-to-analog conversion, and the prompting user bleeds and finishes, and control panel 4 also stops motor 3 immediately automatically.In the utility model, control panel 4 also can be monitored the bad situation of bleeding, as situations such as pumping chamber 11 gas leakage, in case pumping chamber 11 gas leakage, the working condition of motor 3 continues constant, 4 of control panels are made feedback action according to sample analysis and are stopped motor 3, thereby avoid idle situation of bleeding.Tutorial light 41 is indicated, and has visual performance intuitively, improves practicability.

In the present embodiment, extraction pump 2 is an oscillatory type, utilizes the air-breathing and exhaust of diaphragm perseveration.The suction port 21 of extraction pump 2 is extended by a valve 22 and is inserted corresponding pore 12 in the pumping chamber 11, between the inwall of the outer wall of valve 22 and pore 12 seal ring 23 sealings is arranged.Extraction pump 2 is installed in the corresponding receiving groove in the base 13 during assembling, the shape of receiving groove, size just with extraction pump 2 couplings, valve 22 inserts in the interior corresponding pore 12 of pumping chamber 11 down, and utilizes seal ring 23 that both are combined closely, easy for installation, quick, and tightness is good.

The utility model is extraction pump 2 and motor 3 effective combinations, and is combined with the control panel 4 of hard-packed housing 1 and electrical control, realizes the electronic combination of bleeding of self-controlled type, and the bodily form is small and exquisite, carries, easy to use, practical.

More than diagram is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
