Abstract
The utility model relates to a vacuum valve pump, which comprises a press head 2, a fixing cover 5, an upper valve 3, a lower valve 6, an elastic air pump 4, a tubular body 7, a piston block 8 and a bottom cover 9, wherein the lower valve is arranged in the top center of the tubular body, the elastic air pump is jointly arranged in the exterior of the lower valve, the upper valve is arranged in the bottom center of the fixing cover which is arranged on top of the tubular body, the press head is arranged in the fixing cover, the piston block is wrapped in the tubular body and the bottom cover is arranged at the bottom of the tubular body. The utility model has the advantages of non deterioration of the emulsion in the tank for a long time and hydrojetting thoroughly or the like.
Description
The utility model relates to a kind of pump.Be specifically related to a kind of Vacuum valve pump.Mainly be to utilize vacuum sprinkling emulsion in the pump housing.Belong to the spray apparatus technical field.
Common emulsion pump is generally formed by pressing head, the pump housing, upper and lower piston, push rod (valve), metal spring, steel ball and suction pipe etc.Pot bottom is inserted in the suction pipe lower end.Emulsion is sucked by suction pipe in jar, is pressed onto by the upper piston endoporus and presses the head region ejection.There is following deficiency in the emulsion pump of this structure:
1, adopt the suction pipe imbibition, pot liquid is in and extraneous contact condition for a long time, can not guarantee jar interior emulsion matter that remains unchanged for a long period of time, and the shelf-life lacks.And emulsion can not all be sprayed only in jar.
2, need with steel ball and metal spring, a jar interior emulsion contacts perishable for a long time with metalwork, do not meet brand-new environmental requirement.
The purpose of this utility model be to provide a kind of jar in the emulsion matter that remains unchanged for a long period of time, hydrojet is Vacuum valve pump completely.
The purpose of this utility model is achieved in that a kind of Vacuum valve pump, it comprises: press head, fixed cover, upper and lower valve, elasticity air pump, cylindrical shell, piston block and bottom, lower valve places the cylindrical shell top center, the elasticity air pump is sleeved on the lower valve periphery, last valve places fixed cover bottom centre, and fixed cover places the cylindrical shell top, presses head and places on the fixed cover, piston block is packaged in the cylindrical shell, and bottom is installed on the cylindrical shell bottom.
Elasticity air pump of the present utility model is closed plastics spring.
Compare with existing emulsion pump, the utlity model has following advantage:
1, do not adopt suction pipe, directly spray emulsion by vacuum pressure in the pump housing.Pot liquid is in the close state of envelope for a long time, can guarantee jar interior emulsion matter that remains unchanged for a long period of time, long shelf-life.And emulsion can all be sprayed only in jar.
2, need not use steel ball and metal spring, product adopts overall plastic structure, can guarantee that a jar interior emulsion never degenerates, and meets brand-new environmental requirement.
Fig. 1 is a general structure schematic representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the utility model is a kind of Vacuum valve pump, it mainly by cover cap 1, press 2, fixed cover 5, upper and lower valve 3,6, elasticity air pump 4, cylindrical shell 7, piston block 8 and bottom 9 form.Lower valve 6 places cylindrical shell 7 top center, and elasticity air pump 4 is sleeved on lower valve 6 peripheries, and last valve 3 places fixed cover 5 bottom centre, fixed cover 5 places cylindrical shell 7 tops, press 2 and place on the fixed cover 5, piston block 8 is packaged in the cylindrical shell 7, and bottom 9 is installed on cylindrical shell 7 bottoms.Cover cap 1 is set on the cylindrical shell 7.
Depress when pressing head, plastics spring presses down, and produces vacuum in the cylindrical shell, and piston block moves upward along cylindrical shell, and emulsion is pressed onto and presses head region in the valve open, cylindrical shell, and emulsion is ejection fast under the cylinder internal pressure effect.Along with finger pressure stops, pressing head and go up to original position because of spring action, hydrojet stops.
