Description

Manual suction pump

The utility model relates to the air extractor that food fresh keeping is used.

As everyone knows, food can be preserved the long time under the condition of vacuum, grow because bacterium only could breed in the suitable air of temperature, do not have vegetative condition without air, so, in order to prolong the shelf-life of food, just must manage with the bag of store food, bottle, jar, air in the bowl-shape vessel takes out, existing extraction pump unreasonable structure, spring external increases main shaft, poor stability, because seal approach is improper, gas leakage influences its using effect easily simultaneously.

The purpose of this utility model is to avoid the defective of prior art and provides a kind of rational in infrastructure, good stability, pumping process not to have leakage, the manual suction pump that the effect of bleeding is high to society.

The utility model is realized by following scheme: be provided with main shaft in the form of piston and spring in the pump housing, the main shaft top is provided with hand rest, the last omoplate that the lower end is in the pump housing has exhaust hole, the pump housing is provided with the loam cake of spacing main shaft, pump housing bottom is provided with one-way valve and the gas holder that is connected suction pipe, sucker, the lower cover and the pump housing that are fixed on pump housing bottom surface form the air vent that connects one-way valve and gas holder, between main shaft and pump housing inner hole wall, be equipped with seal ring on the junction plane of gas holder and the pump housing, described spring is built-in, is located in the axis hole of the main shaft and the pump housing; Described one-way valve is made up of spool and jam pot cover, and jam pot cover has a breeder tube and air vent to connect; Described sucker below also is provided with the annex of bleeding.

Embodiment elaborates again below in conjunction with accompanying drawing.

Manual suction pump (referring to Fig. 1-8) is provided with main shaft in the form of piston (1) in the pump housing (11) of vertical type, built-in spring (3) is located in the axis hole of the main shaft and the pump housing, and this has shortened main shaft to a certain extent, has improved the stability of extraction pump.

The pop-up on main shaft top (2) and its disjunctor or be adhesively fixed, the lower end has 2 omoplates to be in the pump housing, last omoplate has exhaust hole (12), the pump housing is provided with the loam cake (13) of spacing main shaft, avoid main shaft in the pull process, to leave the pump housing, loam cake is detachable with being connected of the pump housing, the loam cake endoporus has the protruding button (17) of two symmetries, corresponding have two angle square shape grooves (18) that are interlockingly connected on the corresponding position of the pump housing, be provided with " O " RunddichtringO (8) at its two omoplates place on the junction plane of the main shaft and the pump housing.The bottom of the pump housing is provided with one-way valve, this one-way valve is made up of spool (14) and jam pot cover (15), the pump housing of aiming at the spool top has vent, there is breeder tube (16) the jam pot cover lower end, it is bonded in the pump housing hole, the remnants of bonding glue can not influence the upper and lower activity of spool, and must not there be gas leak phenomenon the abutting edge.

Pump housing bottom also is provided with the vertical gas holder of adjacent straight (5), and the purpose that gas holder is set makes and obtains buffering when bleeding, and alleviates spring pressure and make air take out totallyer.Gas holder also is detachable with being connected of the pump housing, and promptly pump housing endoporus has the protruding button (17) of two symmetries, and corresponding have two angle square shape grooves (18) that are interlockingly connected on the corresponding position of gas holder.Detachable connection procedure is two protruding buttons to be injected the straight trough of groove earlier and then rotate an angle make protruding tipping in into translot can link one, also is provided with " O " RunddichtringO (8) on the junction plane of the pump housing and gas holder." O " type circle at two places need be smeared a small amount of silicone oil or silicone grease when assembling.

The bottom surface of the pump housing is provided with the lower cover (10) of bonding one, and it and the pump housing form a horizontal communication road (9) that connects one-way valve and gas holder.In pumping process, to avoid foul, moisture to bring one-way valve into and influence the performance of one-way valve in order to make, on the pump housing, there is a high protruding tracheae (6) to stretch in the gas holder, be the transition tracheae of linking up between air vent and the gas holder, make the foul brought in the gas holder, deposit of moisture at the bottom of jar so that regularly remove.Gas holder connects suction pipe (4), suction pipe connects sucker (7), close-fitting plug type.Sucker (7) below is provided with the annex of bleeding that flexible package or rigid package are used that is used for of unloading arbitrarily.

The described annex of bleeding comprises: if to the flexible package (see figure 5) of bleeding, need to be provided with the hard disk (20) with vent (21) in flexible package, stick the adhesive plaster (19) that two ends can adhesion aiming at the vent position.If to the rigid package (see figure 6) of bleeding, punching out vent (21) on hard disk is aimed at vent and only need be pasted identical adhesive plaster (19) and get final product, as the can of Marko's iron sheet or sheet lead or aluminium leather.To another kind of rigid package bleed (seeing Fig. 7-8), as home-use bowl-shape vessel and so on, comprise the sealing gasket (24) that combines with it, with the bonding sealing cover (22) that links to each other of sealing gasket with vent (21) and macropore, vent is provided with the diaphragm seal (23) of arbitrarily unloading, be the problem that prevents that diaphragm seal is easily lost in the using process, the convex shoulder (25) of circumference uniform distribution is set at the macropore place of sealing cover (22), 3 convex shoulders can be built-in with diaphragm seal, diaphragm seal has plait on (23), and hand is taken when being convenient to unloading.Sealing gasket and diaphragm seal softer rubber or plastic production.

Pumping process is such: sucker (7) is topped outside above-mentioned adhesive plaster (19), when hand rest under the hand (2) makes main shaft (1) in the pump housing (11) during to lower slider, the just discharge in the exhaust hole (12) of omoplate from the main shaft of air in the pump housing, at this moment one-way valve sealing, air just can not enter gas holder (5), when openhanded opening, because the effect main shaft of spring (3) upwards slides, this moment, seal ring was in sealing state, and the one-way valve spool rises and open, air moves in gas holder (5) is drawn onto the pump housing (11) so repeatedly, and air is just constantly extracted out outwards to get rid of reaches the vacuum purpose.When bleeding rigid package, principle is identical, during as Fig. 7-8 bowl-shape vessel are bled, diaphragm seal (23) lifts slightly, and air is just gone out from the vent (21) of sealing cover (22), make and be vacuum state in the bowl, after exhausting gas, diaphragm seal tightly touch vent under the effect of atmospheric pressure, prevents that air from entering, bowl interior food is in the vacuum, and family can directly carry out bleeding fresh-keeping to eating surplus food.Arrest the plait of diaphragm seal (23) during venting and up carry, outer Jie's air just enters vessel, and when the vessel external and internal pressure equated, sealing cover just was easy to open.

1. advantage of the present utility model is. the built-in Rational structure of spring shortens the main shaft height, not only increases aesthetic property, also improves the stability of extraction pump; 2.. adopted well behaved one-way valve structures and sealing configuration, almost do not have leakage in pumping process, exhaust velocity is fast, the pumping efficiency height; 3.. the linkage structure that each assembly is detachable, be convenient to timely disassembly, cleaning gas holder.The utility model is suitable for family especially package bag, bottle, jar, bowl-shape vessel etc. is vacuumized, with the food and extend freshness storage life.
