Abstract
The utility model relates to a manual air pumping barrel which can cause a sealed container to achieve high vacuum degree, and comprises a cylinder barrel, a round tube-shaped piston rod, a handle and a piston, wherein, the round tube-shaped piston rod is arranged in the cylinder barrel, the handle and the piston are respectively and fixedly arranged at both ends of the piston rod, and the piston is externally provided with a piston ring of which the working surface is in a horn shape. A bottom cover of which the one end is provided with an air pumping nozzle of the piston is arranged in the cylinder barrel. The air pumping nozzle is in a cone shape and is a tube-shaped air pumping joint arranged in a radial direction. A piston cavity is pressed and connected with a conical rubber air-exhausting valve core through an elastic pressurizing block. A flexible sealing sheet with a ventilation hole is pressed and connected between one end which is fixedly provided with the bottom cover of the cylinder barrel and the bottom cover. The middle of the flexible sealing sheet is pressed and connected with an air inlet valve core. The manual air pumping barrel can be matched with a sealed container with various types.
Description
The utility model belongs to a kind of extraction pump device, particularly a kind of manual pump bowl that makes resealable container reach higher vacuum.
At present people for the preservation majority of food fresh keeping and protection against the tide, mildew-resistant article be with some easily containers of sealing after the motor-drive pump device vacuumizes, seal again.Its pump-unit complex structure, cost height, often to consume more electric energy, when going out behind the sealed utensil of unpacking, also be not easy to utensil is repeated to vacuumize sealing once more again because of pump-unit heaviness or non-transformer, the pump-unit that has is bled, and the degree of vacuum of back container is low, sealing back is fresh-keeping, moisture effect is not good, particularly be difficult to spread to general in, be extensive use of among the low-income household and under multiple occasion.
The purpose of this utility model is for a kind of simple and easy effective manual pump bowl of bleeding is provided, to overcome the deficiency of prior art.
The purpose of this utility model is achieved in that manual pump bowl includes cylinder barrel, tubular shape piston rod, piston rod one end and is fixed with handle, the other end is fixed with the piston that its cylindrical is being adorned working surface flare piston ring, piston rod is loaded in the cylinder barrel, the end that described piston is housed in cylinder barrel is fixed with the bottom of being with the mouth of bleeding, and the mouth of bleeding on the bottom is bevel-type and the tubular air extraction connector that is radial arrangement.Conical rubber exhaust plug with the crimping of elasticity pressurizing block in the piston cavity.Install between the end face of bottom one end and the bottom crimping at cylinder barrel and the flexible sealing fin that vent is arranged on it, conical rubber air inlet spool in the intermediate portion crimping of flexible sealing fin.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The tubular shape piston rod 4 that manual as shown in Figure 1 pump bowl includes cylinder barrel 3 and is equipped with in cylinder barrel 3.The upper end of piston rod 4 is installing handle 1, and the lower end circle is being adorned cylindrical piston 7.Adorn working surface in the peripheral groove of piston 7 and be trumpet-shaped piston ring 8.Conical rubber exhaust plug 9 with 6 crimping of foamed plastics pressurizing block in the chamber of piston 7.The upper end of cylinder barrel 3 is installing top cover 2, and cylinder barrel 3 lower ends are installing the bottom 10 that the mouth 13 of bleeding is arranged on it.Crimping between the lower end surface of cylinder barrel 3 and the bottom 10 rubber of vent thigh diaphragm seal 15 on it, conical rubber air inlet spool 14 in the intermediate portion crimping of rubber gasket 15.Bleed and external hose 11 is housed on the mouth 13.
On bottom 10, also be fixed with guard shield 12 as shown in Figure 1.
One center hole that is communicated with piston rod 4 inner chambers is arranged on handle 1 as shown in Figure 1.
As shown in Figure 1, in piston 7 chambeies, be fixed with the piston cap 5 that foamed plastics pressurizing block 6 in crimping.
During use, manually the guard shield 12 of pump bowl withstands the mouth 13 of also will bleeding and injects the external hose 11 that is communicated with salable vacuum vessel on fixed object.When bleeding, pulling handle 1 moves on the piston 7, cylinder barrel 3 internal volumes increase, and pressure reduces, under the effect of piston 7 chamber inner foam plastics pressurizing block 6 and pressure reduction, exhaust plug 9 closes, because the vacuum vessel internal air pressure is greater than cylinder barrel 3 internal air pressures, under the pressure difference effect, air inlet spool 14 is opened, gas in the vacuum vessel is by external hose 11, the mouth 13 of bleeding enters in bottom 10 chambeies, and the vent from the rubber compressing tablet 15 enters in the cylinder barrel 3 again, and pumping process is finished.During exhaust, driving handle 1, piston 7 moves down, and the cylinder barrel internal volume reduces, and pressure increases, under the effect of pressure difference and rubber compressing tablet 15, air inlet spool 14 closes in bottom 10 chambeies, the gas circuit in the automatic cut-out and the external world, and the exhaust plug 9 in piston 7 chambeies is opened under differential pressure action, the center hole that piston rod 4 and handle 1 are located to enter in the gap of gas in the cylinder barrel 3 by exhaust plug 9, piston cap 10 and 6 of foamed plastics pressurizing block etc. enters atmosphere, and exhaust process is finished.Several times can be extracted the gas in the vacuum vessel out so repeatedly.
The utility model has the following advantages, and is namely simple in structure, easy to use; Reliable operation, efficient height carry Convenient, cost is low; The vacuum height, it is effective to store food and article; Without any need for the energy; This manually takes out Inflator is because can automatically cutting off and extraneous gas circuit, so can be used with the various ways vacuum tank. Can extensively use Need in tourism, field work, dormitory, family, dining room and restaurant etc. food fresh-keeping store and the article protection against the tide, Insect protected, antipollution occasion.
