Abstract
The utility model relates to a pollution-free emulsion pump, which comprises a pressing head, a guide tube, a pump body, a lock cover, a plunger, a restoring spring, an upper one-way valve and a lower one-way valve, the lock cover is positioned on the upper side of a bottle cover and is fixedly connected with the bottle cover. The utility model is characterized in that the restoring spring is arranged between the outer side of the lock cover and the pressing head.
Description
Technical field:
The utility model relates to a kind of emulsion pump, particularly a kind of free of contamination emulsion pump.
Background technology:
All be provided with the emulsion pump on the existing lotion pump of depositing the daily-use chemical industry emulsion and be used for drawing emulsion in the lotion pump, the metal spring of establishing in its emulsion pump that resets emulsion direct and in the pump contacts, time one is long, metal spring will get rusty and pollute the emulsion that flows out through the emulsion pump, and its life-span reduced greatly after metal spring got rusty in addition; On April 14th, 1999 disclosed the patent No. in the Chinese patent announcement and be 97243110 patent of (Granted publication number be CN2314128Y), disclose a kind of waterproofing mechanism of emulsion pump in this patent, the used retracing spring of the emulsion pump of introducing in it just directly contacts with emulsion in the pump.
Summary of the invention:
Technical matters, the purpose of this utility model provide a kind of free of contamination emulsion pump, and it has solved the problem that the retracing spring that exists in the existing emulsion pump pollutes emulsion in the pump.
Technical scheme:
The purpose of this utility model is achieved in that a kind of free of contamination emulsion pump, comprising: head, conduit, the pump housing, locking closure, piston, retracing spring, last check valve and following check valve; Locking closure is positioned at the bottle cap upside and captives joint with bottle cap, it is characterized in that retracing spring is contained between the locking closure outside and the head.
Described free of contamination lotion pump is characterized in that described head downside is provided with the annular flap that surrounds described retracing spring; Corresponding described retracing spring place, the described locking closure outside have can ccontaining this retracing spring counterbore, the external diameter slip of the annular flap on this counterbore internal diameter and the head matches; The height of annular flap has at least a part to be positioned at this counterbore for annular flap when head is positioned at highest point.The effect of this annular flap and counterbore is that spring is played protection, damages spring in the counterbore in order to avoid foreign material fall into.Beneficial effect
Owing to adopted technical scheme described in the utility model, metal spring does not contact with emulsion, so metal spring can not pollute emulsion, and metal spring is difficult for getting rusty, and prolonged the service life of emulsion pump.
Description of drawings:
Fig. 1 is the inner structure scheme drawing of free of contamination emulsion pump described in the utility model.
Fig. 2 is the described free of contamination emulsion pump of Fig. 1 at be depressed enlarged diagram when being locked on the locking closure of head.
Drawing explanation: 1-head, 101, annular flap, 2-bottle cap, 3-conduit, 4-retracing spring, the 6-pump housing, 7-locking closure, 701, counterbore, 8-piston, 9-switch column, 10-bead, 11-suction pipe.
The specific embodiment:
Fig. 1 is a specific embodiment of free of contamination emulsion pump described in the utility model.As can be seen from Fig. 1, described free of contamination emulsion pump comprises: head 1, conduit 3, the pump housing 6, locking closure 7, piston 8, retracing spring 4, last check valve and following check valve; Wherein go up check valve and be made of conduit 3 bottoms and switch column 9, following check valve is made of the pump housing 6 bottoms and bead 10, and locking closure 7 is positioned at bottle cap 2 upsides and captives joint with bottle cap 2, and head 1 downside is provided with the annular flap 101 that surrounds retracing spring 4; Corresponding retracing spring 4 places, locking closure 7 outsides have can ccontaining retracing spring 4 counterbore 701, the external diameter slip of counterbore 701 internal diameters and annular flap 101 matches; The height of annular flap 101 has at least a part to be positioned at this counterbore 701 for (state shown in Figure 1) annular flap 101 when head 1 is positioned at highest point.
Claims (2)
1, a kind of free of contamination emulsion pump comprises: head, conduit, the pump housing, locking closure, piston, retracing spring, last check valve and following check valve; Locking closure is positioned at the bottle cap upside and captives joint with bottle cap, it is characterized in that retracing spring is contained between the locking closure outside and the head.
2, free of contamination lotion pump according to claim 1 is characterized in that described head downside is provided with the annular flap that surrounds described retracing spring; Corresponding described retracing spring place, the described locking closure outside have can ccontaining this retracing spring counterbore, the external diameter slip of the annular flap on this counterbore internal diameter and the head matches; The height of annular flap has at least a part to be positioned at this counterbore for annular flap when head is positioned at highest point.
