The utility model content
The purpose of this utility model provides the external spring combined suction and force pump of a kind of improved type body, spring members is positioned at combined suction and force pump body top and exposes, carried out structure of modification for piston rod, it is inhaled presses effect better, reduced the contact position between piston and the piston rod downwards, and centering access node structure carries out technical innovation, blocked the possibility of leak of liquid, and the material to the water shutoff pearl changes plastic material into from metal material, reduces the pollution risk of liquid in pump chamber.
The technical scheme of the utility model technical solution problem is such, the external spring combined suction and force pump of a kind of improved type body, by in connect, the pump housing, piston rod, the piston rod cover, piston, spring, the water shutoff pearl, component set-ups such as pad, its architectural feature connects the joint anchor fitting as outside bottle cap in being, outside face is a gear-like vertical line texture, inside is divided into two chambers up and down, upper chamber is used for sheathed piston rod cover and spring, the lower chamber inwall is horizontal negative thread, be used for screwing and engage with container, the lower chamber top has the annular ditch groove structure, be used for the sheathed fixedly pump housing, pad is arranged in the container bottle top and connects the lower chamber engage position, in connect axis hole and be used for sheathed piston rod, the piston rod cover is placed in upper chamber, its outside sheathed spring, piston bush is located on the piston rod, piston rod is a hollow structure, its underpart structure is used to shelve sheathed piston, and symmetrical imbibing hole is arranged, hollow channel bottom UNICOM in two imbibing holes and the piston rod, form " T " font liquid duct, piston is " K " shaped sections structure, outside face is attached at pump housing inwall, the water shutoff pearl is positioned at pump housing bottom liquid sucting port, because pump housing inwall lower position has circular protrusion, and can the water shutoff pearl is movable in the space between pump housing bottom liquid sucting port and circular protrusion.
Described piston rod and piston rod cover, its captive joint mode are by the ring-type ripple glaze of piston rod upper end outer wall and the tight snapping of circular protrusion of piston rod set upper side inwall.
The external spring combined suction and force pump of described a kind of improved type body, according to different embodiment, need on pump housing wall, to settle the constant voltage hole, when pump housing imbibition and after outwards getting rid of liquid, air pressure in the container bottle reduces, extraneous air passes through the constant voltage orifice flow to container bottle in the pump housing, can keep container bottle inner air pressure and external air pressure to reach balance.This technology is widely used in the middle of the lotion pump, is prior art, and invention is applied in the middle of the corresponding embodiment this technology.
The utility model carries out structure of modification to existing cosmetics of everyday use liquid container with liquid distributor makes it more reasonable, make single-piece airtight performance, leak resistance, absorbent better, a lot of parts all are one-body molded, so reduce the product cost greatly, and the metal parts spring is positioned at outside the pump chamber, can effectively prevent the pollution to liquid.
