Abstract

The utility model relates to an emulsion pump including a pressing head 1,a connecting cover 2, a pump body 5, an upper piston 7, a lower piston 10, a spring 9, a push rod 11, a ball 12 and a sucker 6. The upper part of the pump body embeds in a groove and the upper part of a pump jacket inserts into the lower part of the pressing head. An inner jacket extends in the pump body and a spring jacket is arranged on the middle part of the upper piston. The lower end of the spring is arranged in the upper end surface on the inner bottom of the pump jacket. A lower piston jacket is arranged on the lower part of the upper piston. The push rod inserts in the upper piston. The pump jacket of the utility model isolates the inner part of the pump body completely from outside world and has a good stopping property.

Description

The emulsion pump

The utility model relates to a kind of pump.Be specifically related to a kind of emulsion pump.Be mainly used in the ejection emulsion.Belong to hydrojet utensil technical field.

Common emulsion pump is generally formed by pressing head, connecting cover, the pump housing, upper and lower piston, metal spring, ball and suction pipe etc.Its metal spring two ends are set in upper piston lower end and lower piston upper end.There is following deficiency in the emulsion pump of this structure:

1, gapped between upper piston and connecting cover, isolated, foreign matter can enter pump housing inside, and liquid also can ooze out pump housing outside in the pump, causes seepage, and solution can influence the quality of jar interior emulsion with after external substance directly contacts in jar.

2, metal spring directly contacts for a long time with the interior solution of pump, and emulsion is perishable, does not meet brand-new environmental requirement.

The purpose of this utility model is to provide a kind of emulsion pump of good leak tightness.

The purpose of this utility model is achieved in that a kind of emulsion pump, comprise head, connecting cover, the pump housing, upper piston, spring, lower piston, push rod, ball and suction pipe, be characterized in pump housing upper unit one pump block, described pump block is made up of inside and outside cover, inside and outside inner room constitutes a groove, pump housing top is inlaid in the groove of inside and outside inner room, the head bottom is inserted on pump block overcoat top, interior cover stretches in the pump housing, spring housing is contained in the upper piston middle part, the spring lower end places on the upper-end surface, the interior end of pump block, and lower piston is sleeved on the upper piston bottom, and push rod inserts in the upper piston.

Compare with existing emulsion pump, the utility model at pump housing upper unit one pump block, therefore pump block is hedged off from the outer world pump housing inside fully, has following advantage:

1, foreign matter can not enter pump housing inside, and emulsion can not oozed out pump housing outside yet in the pump, has guaranteed the degree of purity of internal emulsion.

2, metal spring does not directly contact with emulsion in the pump, and emulsion undergoes no deterioration, and meets brand-new environmental requirement.

Fig. 1 is a general structure schematic representation of the present utility model.

Fig. 2 is a pump block structural representation of the present utility model.

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

As Fig. 1, the utility model is a kind of emulsion pump, mainly is made up of head 1, connecting cover 2, pad 3, upper piston 7, pump block 8, spring 9, lower piston 10, push rod 11, ball 12, marble sleeve 4, the pump housing 5 and suction pipe 6.

As Fig. 2, pump block 8 is made up of inside and outside cover 13,14.13,14 in inside and outside cover constitutes a groove 15.

The pump housing 5 tops are inlaid in the groove 15 of the inside and outside inner room of pump block, head bottom 1 is inserted on pump block overcoat 14 tops, cover 13 stretches in the pump housing 5 in the pump block, spring 9 is sleeved on upper piston 7 middle parts, spring 9 lower ends place on the upper-end surface, the 8 interior end of pump block, lower piston 10 is sleeved on upper piston 7 bottoms, and push rod 11 inserts in the upper piston 7.

When head is depressed, pressure drives upper piston and lower piston moves down synchronously, length of spring compressed, and pump housing inner volume reduces, push rod and piston space valve open, the interior emulsion of the pump housing sprays through head; Decontrol head, recoil of spring moves on the upper and lower piston, and pump housing inner volume increases, and ball is opened, and emulsion is sucked by suction pipe.
