Abstract

A seal air inlet leakage-proof emulsion pump comprises a press head, a screw tooth, a lock cap, a body, a main post, a secondary post, a piston, a glass ball, a pressure spring and a suction pipe; an air inlet is formed in the upper part of the body; a liquid inlet pipe of the press head is fixedly connected with the upper end of the main post of which the lower end is fixedly connected with the upper end of the secondary post; the seal air inlet leakage-proof emulsion pump also comprises a movable sealing element sleeved on the main post and in sliding match and hydraulically sealed with the main post; the movable sealing element is in sliding match with the inner cavity of the body and matched with the air inlet and the press head. Due to such a structure and the arranging of the movable sealing element, the movable sealing element can seal the air inlet when the press head and the lock cap are locked; when the press head and the lock cap are separated and the press head upwards achieves the highest point, the movable sealing element and the inner cavity of the body at the upper part of the air inlet can be matched to prevent liquid from entering the press head by the air inlet, thus effectively preventing the liquid leakage, eliminating safety loophole and preventing the liquid from contaminating the bottle body.

Under the sealed state of head and locking closure, interface inserts on the feed tube on the head on the cylindrical seats in the annular groove sealed chamber sealing admission port;

Move up when leaving locking closure at head, sealed chamber is positioned at the top of admission port, stretches into intrinsic rounding taper type cylinder on the locking closure and cooperates stop bit with sealed chamber; Cylindrical seats cooperates stop bit with the annular arrangement block plate of principal post bottom;

When head moved down, interface and the annular groove on the head of cylindrical seats were chimeric, and head drives dynamic seal and moves down.

Described a kind of gas port type liquid-leakage preventing emulsion pumps that is sealed into, its special character is: in described principal post and the interface that the feed tube of head is connected the turbination chamber is arranged;

Also comprise a top glass bead, described top glass bead is arranged in the turbination chamber.

Described a kind of gas port type liquid-leakage preventing emulsion pumps that is sealed into, its special character is: axial groove is arranged on the inwall of described cylindrical seats.

A kind of gas port type liquid-leakage preventing emulsion pumps that is sealed into of the present invention, owing to adopting such structure, the setting of sliding seal can be when head and locking closure be sealed, sliding seal seals admission port; Head separates with locking closure, and when head upwards peaked, sliding seal cooperated with the chamber body on admission port top, prevented that liquid from entering head through admission port; Thereby effectively prevent leak of liquid, eliminated potential safety hazard, anti-liquid contamination bottle.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, a kind of gas port type liquid-leakage preventing emulsion pumps that is sealed into, comprise head 1, thread 2, locking closure 3, body 4, principal post 5, subpost 6, piston 7, glass bead 8, pressure spring 9 and suction pipe 10, admission port 41 is arranged at the top of described body 4, the upper end of body 4 is passed thread 2 and is captiveed joint with locking closure 3, head 1 and locking closure 3 screws thread fit; The feed tube 1A of head 1 is captiveed joint with principal post 5 upper ends, captive joint with the upper end of subpost 6 in the lower end of principal post 5, piston 7 is arranged on the lower end of principal post 5, and annular groove on the annular arrangement block plate 51 of the upper end of piston 7 and principal post 5 511 is movable to be cooperated, the lower end cooperates stop bit with the annular table 61 on subpost 6 tops; Inlet 42 places of described body 4 lower ends arrange glass bead 8, and spring perch 43 is arranged at body 4 inner chamber bottoms, and pressure spring 9 lower ends cooperate with spring perch 43, and the upper end cooperates with subpost 6;

Also comprise a dynamic seal 11, described dynamic seal 11 be enclosed within on the principal post 5 and with principal post 5 bearing fits and liquid sealing, the inner chamber bearing fit of dynamic seal 11 and body 4, dynamic seal 11 cooperates with admission port 41;

Dynamic seal 11 cooperates with head 1.

Such as Fig. 4, shown in Figure 5, described dynamic seal 11 comprises cylindrical seats 111, sealed chamber 112 and the Circular Plate 113 that sealed chamber 112 is connected with cylindrical seats 111,

Interface 1111 is arranged at the top of cylindrical seats 111, and the outside face of sealed chamber 112 is curved along axis direction;

Cylindrical seats 111 and principal post 2 bearing fits and liquid sealing, sealed chamber 112 and body 4 inner chamber bearing fit and liquid sealings;

As shown in Figure 4, axial groove 1112 is arranged on the inwall of described cylindrical seats 111, resistance like this between sealing member and the dynamic seal 11 can take in sail.

As shown in Figure 5, the cross section of described sealed chamber 112 is hyperbola.

As shown in Figure 1, under the sealed state of head 1 and locking closure 3, sealed chamber 112 sealing admission ports 41 are arranged in the annular groove 1A1 on the feed tube 1A that interface 1111 inserts on the heads 1 on the cylindrical seats 111;

As shown in Figure 2, move up when leaving locking closure 3 at head 1, sealed chamber 112 is positioned at the top of admission port 41, and the rounding taper type cylinders 31 that stretch on the locking closure 3 in the body 4 cooperate stop bit with sealed chamber 112; Cylindrical seats 111 cooperates stop bit with the annular arrangement block plate 51 of principal post 5 bottoms;

When head 1 moved down, the interface 1111 of cylindrical seats 111 was chimeric with the annular groove 1A1 on the head 1, and head 1 drives dynamic seal 11 and moves down.

In described principal post 5 and the interface 52 that the feed tube 1A of head 1 is connected turbination chamber 521 is arranged;

Also comprise a top glass bead 12, described top glass bead 12 is arranged in the turbination chamber 521. The effect of top glass bead: because piston and principal post interference sealing, piston is broken silicone oil can't evenly make sealing position, and activity has some setbacks after cooperating with principal post, causes the suction mal or without suction, so increase ￠ 4.5mm glass bead and principal post seal; (can not slide) when piston cooperates tension with principal post after the increase, when the head resilience, body interior forms vacuum state, can guarantee that pump head suction is normal; Normal pump liquid.

Above-described only is preferential embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art, in the situation that do not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
