Bottom, in order to which user dismantles the deployment scenarios that the loading plate 12a watches the internal part of host cavity 111.
A kind of embodiment is obtained as of the invention, projection (not shown) is provided with the periphery of the loading plate 12a, it is described
The corresponding projection opens up fluted in the side wall of the adjacent bottom of host cavity 111, and the projection is sticked in the groove, so that
The loading plate 12a is connected with the bottom of host cavity 111.It is understood that certainly can also be in the week of the loading plate 12a
Groove is set on edge, and the corresponding groove is provided with projection, the groove in the side wall of the adjacent bottom of host cavity 111
Engage setting with the projection.
As another embodiment of the invention, screw thread (not shown) can be set on the periphery of the loading plate 12a,
Then correspond to and be threaded in the side wall of the adjacent bottom of host cavity 111, by the loading plate 12a and the host cavity
111 bottom thread connection.
In the present embodiment, the first bleeding point 111a is opened on the loading plate 12a.Specifically, the carrying
The pillar 121 set towards the minipump 13 is provided with plate 12a, the first bleeding point 111a is described to be opened in
The through hole at the center of pillar 121.Preferably, the pillar 121 is cylindrical columns on the loading plate 12a, described the
One bleeding point 111a is the circular through holes for being opened in the center of pillar 121, in order to which the pipeline of air exhaust nozzle 131 is connected to institute
State the first bleeding point 111a.
The minipump 13 is on the fixed frame 12b.In the present embodiment, the fixed frame 12b is
Hollow cylindrical shell 11, and supporting construction is provided with the fixed frame 12b, the part of minipump 13 is located at institute
State in fixed frame 12b, and one end end face of the minipump 13 is connected to the supporting construction.Using the fixed frame
Frame 12b be hollow cylindrical shell 11 design so that the minipump 13 can partial receipt be fixed on
In the hollow bulb of the fixed frame 12b, so as to save the minipump 13 and the fixed frame 12b described
Space-consuming in host cavity 111, the structure setting for being advantageous to the vacuum extractor 10 are more compact.
Further, the first external member 135, the first external member position 135 are arranged with one end of the minipump 13
In the fixed frame 12b, protection is played to be located at one end in the fixed frame 12b to the minipump 13
Effect.
Further, the supporting construction includes reinforcing plate 122 and support column 123, and the reinforcing plate 122 is polylith, point
The fixation is not fixedly connected on along the angled spread configuration in center of the fixed frame 12b, one end of the reinforcing plate 122
Framework 12b inwall, the other end are connected to the outer wall of the support column 123, and the support column 123 is hollow cylinder knot
Structure, one end end face of the minipump 13 are connected to the end face of the support column 123.Specifically, the reinforcing plate 122 is
Square plate, the reinforcing plate 122 is to strengthen the structural strength of the fixed frame 12b, with enough strength supports
The fixed minipump 13.Preferably, the reinforcing plate 122 is three pieces, three pieces of 122 structures triangular in shape of reinforcing plate
It is arranged in the fixed frame 12b.The support column 123 is hollow cylindrical structure, and the support column 123 with
The junction of the wherein two pieces reinforcing plates 122 sets jagged.Because the first bleeding point 111a is located at the fixed frame
In frame 12b, i.e. the first bleeding point 111a is located in the hollow bulb of the support column 123, so as to work as the air exhaust nozzle 131
When being connected to the first bleeding point 111a via connecting pipe (not shown), the breach of the support column 123, Neng Goubian are utilized
In the entrance and stretching of the connecting pipe.
When one end end face of the minipump 13 is connected to the end face of the support column 123, the micro vacuum
The exhaust nozzle 132 of pump 13 is located in the support column 123.Using above-mentioned design, the minipump 13 can be saved in institute
The space-consuming in host cavity 111 being stated, meanwhile, using the breach of support column 123, the exhaust nozzle 132 can also be discharged
Gas is distributed to the other positions in the host cavity 111.
The minipump 13 includes the pump housing 13a and motor 13b being electrically connected with the circuit board 15, the pump housing
For 13a on support frame as described above 12, the relative degree of vacuum of the pump housing 13a is -50kpa~-90kpa.In the present embodiment, institute
State pump housing 13a and be located at the support column 123, so that the support column 123 is played a supporting role to the pump housing 13a.By institute
The relative degree of vacuum for stating pump housing 13a is -50kpa~-90kpa, therefore, when the utilization vacuum extractor 10 is to container to be connected
When vacuumizing, also holding -50kpa~-90kpa vacuum is enabled in container to be connected, and then ensures to be stored in described
Food fresh-keeping in container to be connected.
In the present embodiment, the motor 13b can use 1W~40W for direct current generator 13b, the motor 13b power,
Operating voltage uses DC3V~36V, to reduce energy consumption.Specifically, when out of doors, entered using the power supply 14a components 14
During row power supply, because the power of the motor 13b is relatively low, and operating voltage is relatively low, vacuumizes and reduces therefore, it is possible to realize
Energy consumption, greatly reduce in vacuum due to energy consumption is too high and cause the power supply 14a electricity to exhaust and can not be after
The continuous probability vacuumized.Simultaneously as the energy consumption of the motor 13b is relatively low, during therefore, it is possible to extend the use of the battery
Between.Preferably, in order to further reduce energy consumption, the use of the vacuum extractor 10 occasion of no civil power such as out of doors is extended
Time, the power of the motor 13b can use 1W, 2W, 3W, 5W, 10W or 15W etc., the rated operational voltage of the motor 13b

It is a kind of knot of evacuation storage device 20 provided in an embodiment of the present invention also referring to Fig. 2, Fig. 7 to Figure 10
Structure schematic diagram.The evacuation storage device 20 includes container 21 and vacuum extractor 10 described above, the vacuum means
Put 10 and be removably connected to the container 21.The vacuum extractor 10 to the container 21 to vacuumize, to keep
The freshness of food in the container 21.
Preferably, the mode and the container 21 that the vacuum extractor 10 can be connected through a screw thread or snap connection
Connection.
The the second bleeding point 21a for being communicated to above-mentioned first bleeding point 111a is offered on the container 21, in order to gas
Can be via the second bleeding point 21a to the first bleeding point 111a outlets.In the present embodiment, the container 21 can be
Cup, crisper or sack.And preferably, the sack is the poly-bag with sealing joint strip.
In the present embodiment, the evacuation storage device 20 also includes check valve 22, and the check valve 22 is located at described
On second bleeding point 21a, offer to be communicated to the air-flow groove 22a of the second bleeding point 21a on the check valve 22,
The first bleeding point 111a is connected with the air-flow groove 22a and forms gas channel, so that the gas in the container 21
Can be via the air-flow groove 22a to the first bleeding point 111a to the air inlet of air exhaust nozzle 131.Due to the check valve
22 setting so that air-flow can only not allow to air inlet in container 21, so as to protect from the container 21 to outside outlet
Hold the vacuum state in container 21.
The shape of cross section of the second bleeding point 21a is stairstepping, including horizontal abutting part 211 and with the level
The vertically disposed vertical abutting part 212 of abutting part 211, the check valve 22 include valve body 22b and respectively extend from the valve
