Description
Technical field
The utility model relates to a kind of pump used in everyday, particularly relates to a kind of pump that has vacuum pumping device.
Background technique
At present, pump used in everyday is a kind of inflatable tool of inflating for vehicle tyre and sport ball class etc. of being mainly used to.Raising along with people's life, in depositing, family's food fresh-keeping and clothing need situation about vacuumizing more and more for packing, press for a kind of small-sized easy instrument that vacuumizes, because above-mentioned pump does not possess the function of bleeding, therefore can only purchase special use separately vacuumizes instrument.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of pump with vacuum pumping device is provided, to satisfy the demand.
For achieving the above object, the technological scheme that the utility model adopted is: a kind of pump with vacuum pumping device, comprise body 1, base 14, be arranged on piston 3 and the piston rod 5 in the body 1 and be arranged on the gas tank 13 of the band pressure pneumatic tube 15 on the base 14, piston rod 5 upper end portions are connected with handle 6, upper end cap 7 is arranged on the upper end-hole of body 1, it is characterized in that: the threeway ozzle 9 of dress one-way valve 10 in described upper end cap 7 one sides are provided with, the outlet side of threeway ozzle 9 is communicated with body 1 inner chamber through upper end cap 7 passages, its air inlet termination is equipped with the vacuum exhaust pipe 12 of clip 19, termination pressure vacuum gauge 11 on it.Piston 3 is provided with the annular groove that is used to place seal ring 4.Described piston rod 5 the inwall by the hole on the upper end cap 7 be provided with the annular groove that is used to place seal ring 8.The last plane 16 of described piston 3 annular grooves is the inclined-plane, and lower plane 17 is provided with breach 18.
The utility model compared with prior art has the following advantages: 1, realized one-object-many-purposes, made the existing aerification function of the pump function of bleeding again; 2, can realize aerification function simultaneously and vacuumize function, also can only realize wherein a certain function; 3, for daily life provides convenience, only need manpower, do not need other energy, saved spending.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model piston 3.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is the annexation schematic representation of the clip 19 and the mouth 20 of bleeding.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, body 1 is connected with upper end cap 7 with base 14 through sealing gasket 2, and the piston 3 in the body 1 is installed in the lower end of piston rod 5, and handle 6 is installed in the upper end of piston rod 5; The gas tank 13 that is used to inflate is installed in the base 14 of body 1 side, communicates through the inner chamber of passage with body 1, and the air outlet of gas tank 13 connects pressure pneumatic tube 15, during the inflation operation, the air outlet of pressure pneumatic tube 15 be inflated object and link to each other.The threeway ozzle 9 of dress one-way valve 10 in upper end cap 7 one sides are provided with, the outlet side of threeway ozzle 9 is threaded with upper end cap 7, and passage on upper end cap 7 and the connection of body 1 inner chamber; The other two ends of threeway ozzle 9: go up termination pressure vacuum gauge 11, air inlet termination vacuum exhaust pipe 12.When bleeding operation, the mouth 20 of bleeding of the band one-way valve on the clip 19 on the another port of vacuum exhaust pipe 12 and the vacuum packaging bag links to each other.Ball valve 10 is set in the threeway ozzle 9, realizes the function that the utility model device is bled from outside to inside by this one-way valve.Piston rod 5 the inwall by the hole on the upper end cap 7 be provided with the annular groove that is used to place seal ring 8, in order to guarantee that when piston rod 5 moves up and down from then on body 1 inside and outside gas can not circulate.
As shown in Figures 2 and 3, described piston 3 is provided with the annular groove that is used to place seal ring 4, and the last plane 16 of piston 3 annular grooves is the inclined-plane, and lower plane 17 is provided with breach 18; Described piston rod 5 the inwall by the hole on the upper end cap 7 be provided with the annular groove that is used to place seal ring 8.The internal diameter of seal ring 4 is greater than the external diameter of the annular groove part of piston 3, when piston 3 moves upward, produce the slit between seal ring 4 and piston 3 annular groove cylinders, the intraluminal gas in piston 3 tops can flow in the tube chambers of bottom through the breach 18 of slit between seal ring 4 and piston 3 annular groove cylinders and piston bottom, guarantees to put forward on piston 3 smoothly the proper functioning with the utility model device.
As shown in Figure 4, the mouth 20 of bleeding of band one-way valve comprises valve gap 21, valve rod 22 and is enclosed within spring 23 on the valve rod 22.Valve gap 21 is fixed on the end of valve rod 22 near valve opening, under spring 23 elastic force effects, valve gap 21 sealing covers are on valve opening, only when bleeding operation, because the negative pressure in the pump makes the interior gas of vacuum packaging bag overcome the elastic force of spring 23, pushes valve gap 21 open, enter in the pump by valve opening, realize the function that vacuumizes of above-mentioned pump.
