Abstract
The utility model relates to an enclosed perfume pump and comprises a honk head 1, a nozzle 2, a pressing cap 7, a pump body 12, an upper piston 3, a lower piston 9, a top bar10, spring 6 and 11, a ball 14 and a suction pipe 15, and is characterized in that an internal sleeve and an external sleeve are arranged on a lower part of the upper piston 3, and a groove 18 is formed between the internal and external sleeves. An upper end of the lower piston 9 is inserted in the groove 18 between the between the internal and external sleeves. The external enclosed type between the upper and the lower pistons changes to the internal and external sleeve enclosed type, so that the upper and lower pistons can match under a long pressing state and is free of deformation, and the sealing performance is good for ensuring that the whole perfume pump is free of leakage.
Description
The utility model relates to a kind of pump.Be specifically related to a kind of closed perfume pump.Be mainly used in perfumes.Belong to the spray apparatus technical field.
Common perfume pump is generally formed by pressing head, nozzle, gland, the pump housing, upper and lower piston, push rod (valve), spring, ball and suction pipe etc.The sealing mode of its upper and lower piston is an external closing type, and promptly lower piston is sleeved on the upper piston.During spraying, depress and press head, valve is opened thereupon, and perfume is pressed onto mentioned nozzle area by the upper piston endoporus in the pump housing.Perfume is ejection fast under the effect of pump internal pressure.Under long-term pressured state, the easy expansion of lower piston can not return, and upper and lower piston space gap increases, and closure is poor, causes the perfume pump to leak easily, influences sprayability.
The closed perfume pump that provides a kind of upper and lower piston space closure good is provided the purpose of this utility model.
The purpose of this utility model is such realization: a kind of closed perfume pump, comprise and press head, nozzle, gland, the pump housing, upper piston, lower piston, push rod, spring, ball and suction pipe, the upper piston bottom is provided with inside and outside cover, inside and outside inner room constitutes a groove, and lower piston is inserted in the inside and outside inner room groove of upper piston.
Compare with existing external closing type perfume pump, because it is that inside and outside two cover is closed that the utility model changes outer closure with upper and lower piston space, make to be engaged in the long-term pressured state indeformablely between the upper and lower piston, upper and lower piston space closure is good, it is tight to reach cooperation, guarantees its sealing.
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 is that upper and lower piston of the present utility model cooperates figure.
Below in conjunction with accompanying drawing the utility model is described in further detail:
As Fig. 1, the utility model is a kind of closed perfume pump.Mainly by press 1, nozzle 2, upper piston 3, electrochemical aluminium gland 4, O RunddichtringO 5, upper spring 6, gland 7, packing ring 8, lower piston 9, push rod (valve) 19, lower spring 11, the pump housing 12, upper spring seat 13, steel ball 14 and suction pipe 15 form.
As Fig. 2, upper piston 3 bottoms are provided with inside and outside cover 16,17, and inside and outside inner room constitutes a groove 18, and lower piston 9 tops are inserted in the inside and outside inner room groove 18 of upper piston.It is tight to reach cooperation, guarantees its sealing.
Depress when pressing head, steel ball is tightly sealed pump housing bottom because of pressure, makes the interior perfume of the pump housing can't flow to the pump bottom.Move downward along with pressing head, valve is opened thereupon.Behind the valve open, perfume is pressed onto mentioned nozzle area by the upper piston endoporus in the pump housing, and perfume is ejection fast under the effect of pump internal pressure.Along with finger pressure stops, pressing head and go up to original position because of spring action, piston also because of popped up by spring force, becomes vacuum in the pump housing, and valve ball upwards floats because of external pressure, and perfume enters in the pump housing once more, forms the circulation spray process.
