Above-mentioned vacuum pumping device be removably connected to described on cover, include but not limited to the modes that removably connects such as being connected by buckle between vacuum pumping device with upper cover, be threaded.The mode that removably connects between this vacuum pumping device and upper cover, vacuum pumping device and sealing case reliably can be linked together, also need not locate with hand in operation always, make simple operation, whole-course automation, and overcome and do not aim at bleeding point because of vacuum pump in prior art and cause vacuumizing the not high drawback of efficiency.And can realize sealing between vacuum pumping device and upper cover air tight owing to arranging elastomer seal, improve further and vacuumize efficiency.
Further, fastener is established in the bottom surface of described shell, arranges the draw-in groove with described fastener adaptation at the upper surface of described upper cover.As equivalent, also can establish draw-in groove in the bottom surface of shell, corresponding establishes the fastener with draw-in groove adaptation at the upper surface of upper cover.
Further, the bottom of protrusion is set in the periphery of described intakeport in the bottom surface of described shell, described bottom establishes fastener; Described upper cover upper surface and be provided with the locating slot of accommodating described bottom in the periphery of described bleeding point, the draw-in groove with described fastener adaptation is set in described locating slot.As equivalent, the bottom of protrusion also can be established at the upper surface of upper cover, and the locating slot establishing adaptation with it in the bottom surface of shell of correspondence.
Further, be provided with air pressure inductor in described shell, described air pressure inductor is connected with a main control module electrical signal, and the pressure information in the sealing case that this main control module senses according to air pressure inductor starts or closes described vacuum pump.When to after exhausting vacuum in sealing case, after a period of time placed by the sealing case being in vacuum state, if box internal air pressure declines, when air pressure inductor detects that box internal air pressure drops to setting value, this signal is reached main control module by air pressure inductor, main control module sends signal enabling vacuum pump, vacuum pump starts to vacuumize sealing case, when air pressure inductor detects that box internal air pressure reaches setting value, this signal is reached main control module by air pressure inductor, main control module sends signal at stop vacuum pump, thus makes box internal air pressure maintain a standard level always.
Further, described elastomer seal in the form of a ring.
The utility model owing to having simple operation, whole-course automation, to vacuumize efficiency high and can maintain the constant advantage of sealing case internal pressure, can be used for various vacuum pumping device.

Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.
Embodiment one
As shown in Figure 1,2 and 3, a kind of vacuum pumping device, comprise the sealing case for vacuumizing, described sealing case comprises the upper cover 1 and lower box 2 that connect, described upper cover 1 arranges vacuum pumping device 3, described vacuum pumping device 3 comprises shell 31, vacuum pump 32 and intakeport 33, and described vacuum pump 32 is arranged in described shell 31; Described intakeport 33 is docked and connected with the connection mouth of bleeding of described vacuum pump 32, and described intakeport 33 is arranged on the bottom surface of described shell 31; Described upper cover 1 arranges bleeding point 11; Described vacuum pumping device 3 is removably connected on described upper cover 1, and described intakeport 33 is docked and connected with described bleeder hole 11; Elastomer seal 4 is in the form of a ring provided with between described vacuum pumping device 3 and described upper cover 1.
The bottom 34 of protrusion is set in the periphery of described intakeport 33 in the bottom surface of described shell 31, described bottom 34 establishes fastener 35.Described upper cover 1 upper surface and be provided with the locating slot 12 of accommodating described bottom 34 in the periphery of described bleeding point 11, the draw-in groove 13 with described fastener 35 adaptation is set in described locating slot 12.Thus make bottom 34 accommodating be positioned to connect in locating slot 12 and by buckle vacuum pumping device 3 is reliably connected on upper cover 1.The mode that removably connects between this vacuum pumping device 3 and upper cover 1, vacuum pumping device 3 and sealing case reliably can be linked together, also need not locate with hand in operation always, make simple operation, whole-course automation, and overcome and do not aim at bleeding point because of vacuum pump in prior art and cause vacuumizing the not high drawback of efficiency.And can realize sealing between vacuum pumping device 3 and upper cover 1 air tight owing to arranging elastomer seal 4, improve further and vacuumize efficiency.
Be provided with air pressure inductor in shell 31, described air pressure inductor is connected with a main control module electrical signal, and the pressure information in the sealing case that this main control module senses according to air pressure inductor starts or closes described vacuum pump.When to after exhausting vacuum in sealing case, after a period of time placed by the sealing case being in vacuum state, if box internal air pressure declines, when air pressure inductor detects that box internal air pressure drops to setting value, this signal is reached main control module by air pressure inductor, main control module sends signal enabling vacuum pump, vacuum pump 32 starts to vacuumize sealing case, when air pressure inductor detects that box internal air pressure reaches setting value, this signal is reached main control module by air pressure inductor, main control module sends signal at stop vacuum pump 32, thus makes box internal air pressure maintain a standard level always.
