In described shell, be provided with locating plate 11 and bracing frame 12, between described locating plate and bracing frame, leave space, booster fan is stuck between locating plate and bracing frame, one end of motor is placed in the positioning groove of outer casing inner wall, the other end is placed on the draw-in groove on locating plate, the shape of bracing frame and the profile of ejector match, and ejector is placed on bracing frame, and the exit end of booster fan and the entrance point of ejector are connected together.
Beneficial effect
1, form negative pressure by the rapid flow of air-flow in ejector, by negative pressure, the air in sealing bag and steam are siphoned away, make formation vacuum in sealing bag, reduce the boiling point of water, the water evaporates of having accelerated article, is sucked out sealing bag, thereby has realized quick-drying object;
2, miniaturization low-power consumption and being easy to carry.
Brief description of the drawings
Fig. 1 is stereoscopic structural representation of the present utility model;
Fig. 2 is that the utility model takes off the stereoscopic structural representation after flexible pipe and interface;
Fig. 3 is the local section of Fig. 2 figure that pops;
Fig. 4 is the three-dimensional cross-sectional view of ejector of the present utility model;
Fig. 5 is the three-dimensional cross-sectional view of interface of the present utility model.
Detailed description of the invention
If Fig. 1 is to as shown in Fig. 3, a kind of vaccum-pumping equipment, mainly formed by shell 1 and the fluidic device that is placed in shell, on shell, be provided with switch and power supply/power input interface, whether switch works for control jet device, and described fluidic device mainly comprises the motor 2, booster fan 3 and the ejector 4 that connect successively.
As shown in Figure 4, described ejector is the venturi tube structure that large centre, two ends dwindles, the entrance point of ejector 4 is connected with the exit end sealing of booster fan 3, the exit end of ejector is positioned at the outer wall of shell, between the entrance point of ejector and exit end narrow position be provided with to outer process communicate with ejector bore passages connect mouth 41, described connects mouth away from the end of ejector and one end of a flexible pipe 42 socket, and the other end of flexible pipe is connected with interface 43.Need to use time just by flexible pipe and interface with connect mouth and be connected, while use, flexible pipe and interface are taken off from connecing mouth, conveniently deposit.
As shown in Figure 5, the one-way exhaust valve on described interface and sealing bag matches, and interface screws fastening on one-way exhaust valve; On the casing wall around booster fan, be provided with ventilation inlet; Open after switch, motor operations, drives booster fan to rotate, and extraneous air is sucked by ventilation inlet, after supercharging, blow into the entrance point of ejector, blow out shell from the exit end of ejector again, out-of-date when air-flow high velocity stream in ejector, can produce negative pressure at the narrow position of ejector, simultaneously in mouth, produce negative pressure connecing, thereby form draught head connecing between mouth and vacuum seal bag, air and steam in vacuum seal bag are flowed to connecing mouth, enter in ejector along with air flow stream goes out shell.
In described shell, be provided with locating plate 11 and bracing frame 12, between described locating plate and bracing frame, leave space, booster fan is stuck between locating plate and bracing frame, one end of motor is placed in the positioning groove of outer casing inner wall, the other end is placed on the draw-in groove on locating plate, the shape of bracing frame and the profile of ejector match, and ejector is placed on bracing frame, and the exit end of booster fan and the entrance point of ejector are connected together.
It is directly to realize from sealing bag suck by booster fan mostly that vacuum seal bag vacuumizes, the utility model is while air-flow being blown over to ejector by booster fan, produces powerful negative pressure siphon away air and the steam in vacuum seal bag in the narrow position of ejector.
Need dry clothing if settled in vacuum seal bag, according to the boiling point principle of water, in the time of a barometric pressure, the boiling point of water approaches 100 degrees Celsius, under equal ambient temperature, in the time that air pressure diminishes, the boiling point of water also can reduce accordingly, the boiling point of water has reduced, under equal ambient temperature, water is also just more easily evaporated, therefore, after sealing bag is vacuumized, because the air pressure in sealing bag sharply reduces, therefore, moisture content in clothing also just can be evaporated faster, the steam being evaporated is discharged in outside air by connecing after mouth is sucked into ejector, therefore, clothing also just can be dried rapidly.
Same, in vacuum seal bag, settle other article, also can, by the principle of work of ejector, sealing bag be vacuumized.
Above-described embodiment is only for interpretation purposes of the present utility model; and be not to restriction of the present utility model, those skilled in the art, in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
