Abstract
The utility model relates to a pedal type exhaust vacuum pump which comprises a pedestal, a cylinder barrel and a piston. The exhaust vacuum pump is characterized in that the cylinder barrel is arranged on the pedestal; the piston is arranged inside the cylinder barrel; the upper part of the piston is provided with a spring; a bracket with a directive wheel is arranged on the pedestal; a foot board is arranged on the bracket; a traction rope is arranged on the foot board and enters the cylinder barrel from the top of the cylinder barrel along the directive wheel and is connected with the piston; the lower part of the cylinder barrel is provided with an air suction and exhaust hole; an exhaust combination valve is arranged on the air suction and exhaust hole; and an air suction nozzle and an air exhaust hole are arranged on the exhaust combination valve. The pedal type exhaust vacuum pump has the advantages of having convenient carrying, needing no power and effectively extracting vacuum in a special fresh-keeping bag with an air exhaust nozzle.
Description
Technical field
The utility model relates to a kind of foot-operated vacuum pump for vent.
Background technique
Present vacuum-packed body is all produced on production line, what need that vacuum freshness retaining makes is article for sale to fresh in the market, because businessman does not have desirable application of vacuum instrument, generally can only adopt plastic wrap to handle, or do not do any processing and sell, greatly influenced the commodity freshness.
Summary of the invention
The purpose of this utility model provides a kind of power that is convenient for carrying, need not, the foot-operated vacuum pump for vent that can vacuumize the fresh-keeping bag specially that has exhaust nozzle effectively.
The purpose of this utility model is realized by following mode:
The utility model comprises pedestal, cylinder barrel, piston, it is characterized in that: cylinder barrel is located on the pedestal, piston is located in the cylinder barrel, is provided with spring on piston top, is provided with the support that has upper saw pulley on pedestal, foot treadle is housed on the support, foot treadle is provided with tow rope, and the top of tow rope along upper saw pulley from cylinder barrel enters cylinder barrel and be connected with piston, have in the bottom of cylinder barrel take out, exhaust port, take out, the exhaust combination brake switch and proporting be housed on the exhaust port, bleed on the exhaust combination brake switch and proporting and chew and exhaust port.
The utility model has the advantages that: easy to carry, need not power, can be effectively to having the fresh-keeping bag specially extracting vacuum of exhaust nozzle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, the utility model comprises pedestal 1, cylinder barrel 5, piston 4, cylinder barrel 5 is located on the pedestal 1, piston 4 is located in the cylinder barrel 5, be provided with spring 6 on piston 4 tops, on pedestal 1, be provided with the support 8 that has upper saw pulley 10, foot treadle 9 is housed on the support 8, foot treadle 9 is provided with tow rope 7,5 top enters cylinder barrel 5 and is connected with piston 4 tow rope 7 along upper saw pulley 10 from cylinder barrel, have in the bottom of cylinder barrel 5 take out, exhaust port, take out, exhaust combination brake switch and proporting 2 be housed on the exhaust port, bleed on the exhaust combination brake switch and proporting 2 and chew 3 and exhaust port, bleed chew 3 and exhaust port be check-valve port.
During use, chew 3 docks with the exhaust nozzle of fresh-keeping bag specially bleeding on the exhaust combination brake switch and proporting, step foot treadle 9, the tow rope 7 of foot treadle 9 drives piston stroking upward, and the exhaust port of exhaust combination brake switch and proporting 2 seals, bleeds to chew and open, and the air in the fresh-keeping bag specially is extracted out, unclamp foot treadle 9, piston 4 is descending under the effect of spring 6, and sealing is chewed in bleeding of exhaust combination brake switch and proporting 2, exhaust port is opened, and the air in the cylinder barrel is discharged.This is a circulation, repeats above-mentioned action, fresh-keeping bag specially can be got vacuum.
