Embodiment 1
[0045] like figure 1 and 2 As shown, a miniature vacuum machine with its own power supply includes a casing, an elastic sealing cover 2, an accessory support seat 3, a power supply 4 and a vacuum pump 5, and it is characterized in that the power supply 4 and the vacuum pump 5 are fixed on the accessory support seat 3 Above, the accessory support seat 3 is connected to the elastic sealing cover 2, and the elastic sealing cover 2 is provided with a suction hole 12, and the suction hole 12 is connected to the intake nozzle 9 of the vacuum pump, and the vacuum pump is connected to the power supply 4 through a switch.
[0046]Further, the housing includes an upper cover 6 and a lower cover 1, and the vacuum pump has a built-in motor and a turbofan, and the motor drives the turbofan to rotate.
[0047] Further, an isolation plate 22 for the motor and the power supply is provided on the accessory support base 3 . The accessory support seat is provided with a hole column 21, and the...
Embodiment 2
[0049] like Figure 1-3 As shown, a method of using a miniature vacuum machine with its own power supply,
[0050] The invention provides a method for using a miniature vacuum machine with its own power supply, which includes the following steps:
[0051] like Figure 4 As shown, at first the miniature real machine is placed on the vacuum compression bag 31 one-way exhaust valve 33; Figure 5 As shown, the miniature vacuum machine does not need to be held by hand, and the downforce generated by the gravity perpendicular to the ground is sealed with the vacuum compression bag, and then the switch is turned on to pump air; finally, the micro vacuum machine is removed after the pumping is completed;
[0052] Wherein, the miniature vacuum machine with its own power supply includes a housing, an accessory bracket seat 3, a vacuum pump 5 and a power supply 4, and it is characterized in that the vacuum pump 5 and the power supply 4 are all fixed on the accessory bracket seat 3, and...
Embodiment 3
[0057] like Image 6 As shown, the lower surface of the elastic sealing cover is provided with a circular concave surface 13, and an annular boss 14 is provided around it. The lower surface of the present invention is the contact surface with the vacuum compression bag. like figure 1 As shown, an exhaust channel 15 is provided on the side of the elastic sealing cover, which communicates with the air outlet nozzle 10 of the vacuum pump.
[0058] Wherein, the height difference between the boss and the concave surface is shown in Table 1 below, and the material hardness is the same as 50 (Shore A type) and the width of the boss is the same as 12mm. Take several vacuum compression bags with a size of 20cm*30cm, and When the contents are half full, carry out the vacuum test 10 times, and count the average time of vacuuming.
[0059] Table 1
[0060] height difference(mm)
[0061] It can be seen from the above table 1 that when the height difference is small, the chann...
