Having in the past bled, and all cost is higher to fill the sealed in unit of atmosphere gas and enclosing function, and volume and power consumption are bigger, are not suitable for general family and use.

The purpose of this utility model is to provide a kind of having of being fit to that general family uses to bleed or the vacuum package device of inflation and enclosing function.

Described vacuum package device comprises a valve, be equipped with in the valve and prevent that foreign material from entering the filter of the pump housing, the pore of valve connects a tracheae and is connected with electromagnetic valve, described electromagnetic valve links with the change-over swith of bleeding/inflate, and there is an end to connect threeway by another tracheae, in addition two the diaphragm type vacuum pumps of two terminations and the pump cup of the threeway composition pump housing that is connected as a single entity, and be connected with the pump active plate is equipped with a block permanent magnet at an end of the close electromagnetic driver of active plate; Described vacuum packaging machine comprises a upper-cover, in its front left side a little thimble is arranged, and aims at the micro-switch AN3 in control electromagnetic driver loop; The alternating current positive pole of 220V/50HZ connects electromagnetic driver, and negative pole meets micro-switch AN3, and the other end of AN3 is by another micro-switch AN1, connect switch pump, another termination electromagnetic driver of switch pump links to each other with positive source, another termination switch circuit of electromagnetic driver; Described vacuum packaging machine also comprises two heat seal keys in upper-cover the place ahead, the heat seal key is connected with depression bar, two top pin at depression bar middle part are aimed at the spring of valve, the little thimble of depression bar right-hand member is aimed at the micro-switch AN1 of master cock circuit, the potential device AN2 of the adjustable heat-sealing time of a termination of AN1, AN2 is communicated with switch circuit, and the sample resistance on the switch circuit connects and seals indicator lamp, output termination heat seal voltage transformer, the heat seal voltage transformer connects two thermoelectric wires.

Example below in conjunction with accompanying drawing is further narrated the utility model.Wherein:

Fig. 1 opens birds-eye view behind the upper-cover for the utility model.

Fig. 2 is an outside drawing of the present utility model.

Fig. 3 is a back view of the present utility model.

Fig. 4 is a non-contact switch circuit schematic diagram of the present utility model.

Fig. 5 is a pump housing assembly drowing of the present utility model.

Fig. 6-1 and Fig. 6-2 is depression bar front view of the present utility model and lateral plan.

Fig. 7-1 and Fig. 7-2 is the front view and the lateral plan of heat seal voltage transformer.Fig. 7-3 is heat seal transformer lines figure.

Fig. 1, Fig. 2 have provided principal organ of the present utility model and functional element figure; The loading and unloading scheme drawing that Fig. 3 marked exhausr port, fill the atmosphere gas mouth and need to clean or change filter, promptly take off bonnet (12) after, must be noted that the rubber cap (14) that when filter (13) restores, is locked; In the non-contact switch circuit schematic diagram from Fig. 4 as can be seen, it adopts the alternating current of 220V/50HZ, by two micro-switch AN1, and AN3 and switch pump KCD3 control heat seal voltage transformer T1 and electromagnetic driver T2, after two micro-switchs are connected, micro-switch AN3 connects switch circuit and disconnects the electromagnetic driver circuit, and electromagnetic driver is not worked because of outage, and bleeding stops, meanwhile, switch circuit work, the heat seal voltage transformer starts, and heating wire begins heating.The AN2 that regulates the heat-sealing time can make the heat-sealing time adjustable in second at 3-15, has noiseless, no spark, the characteristics that the life-span is long; Fig. 5 is the pump housing that diaphragm type vacuum pump and pump cup are integrated, and the utility model adopts two parallels connection of pumps, and it is fast to have pumping speed, and it is stable to bleed, and degree of vacuum is up to 0.035MPA; The design of pressure lever mechanism among Fig. 6 has multi-functional:, make the automatic retraction of valve; 2, termination of pumping heat-sealing translation function; 3, compress the plastics sack and guarantee the reliable function of heat-sealing; Heat seal voltage transformer among Fig. 7 has core section long-pending little (only 7.8 sq cms), the characteristics of horsepower output height (can reach 70W).

Principle of work of the present utility model is achieved in that opens upper-cover (1), the change-over swith (2) of will bleeding/inflate places bleed position, look the selected heat sealed time of plastic bag thickness adjusted heat-sealing time knob (6), with pulling outlet nozzle (8), with be equipped with need packaged articles plastic bag cover on valve, flatten sack; Cover cover, snap close on the cover plate (7) pins automatically up and down, micro-switch AN3 is logical, press switch pump (4) power connection, alternating current forms alternating magnetic field by the magnetic pole in the electromagnetic driver, active plate on the diaphragm type vacuum pump is in action of alternating magnetic field lower compression/stretching pump cup (16) reciprocating extrusion, thereby the mold cavity volume in the change pump housing, produce draught head, driving pump valve sheet (15) instigates, gas in the plastic bag through extracting out with exhausr port (11) bonded assembly tracheae, is close to packed article until the bag wall, bleeds and finish; Charge into atmosphere gas as need, the change-over swith that only needs will bleed/inflate places aerating position, and this moment, electromagnetic valve started, and the atmosphere gas that mixes up air pressure is in advance inflated in plastic bag through tracheae and valve from filling atmosphere gas mouth (10).

Bleed/inflate finish after, both hands are pressed heat seal key (9), and depression bar moves downward, and the top pin that is in the depression bar middle part is return valve, meanwhile, the little thimble of depression bar right-hand member touches micro-switch AN1, and the electromagnetic driver loop is disconnected, and by logical switch circuit, the heat seal voltage transformer starts, to heating wire power supply, heating of plastic sack, it is bright to seal indicator lamp; After reaching the heat seal setting-up time, AN2 disconnects, open circuit, and indicator lamp goes out, and heat-sealing is finished, and the openhanded heat seal key of opening is opened upper-cover, takes out the plastic bag of sealing, and checks seal quality.

The utility model is because adopted diaphragm micropump formula vacuum pump, and non-contact switch circuit and fast speed electromechanical interlocks compare with existing vacuum packaging equipment, compact conformation, and volume is little, degree of vacuum height (can reach 0.035MPA), pumping speed is fast, and is easy to operate; In addition, fuselage cover adopts ABS, and cost is low, uses so be fit to general family.
