Description
Technical field
The present invention relates to a kind of device for vacuumizing to vacuum-pumping density envelope, belonging to the optimization technique that sealing bag vacuumizes.
Background technology
Existing vacuum-pumping density envelope, normally air pump manually vacuumizes, or is vacuumized by the electronic instrument that vacuumizes, such as dust collecting fan.Hand air pump uses relatively harder, needs the long period just can reach the effect vacuumized.Power tool vacuumizes instant effect, remarkably productive, but a lot of family is not equipped with and electronicly vacuumizes instrument, and power is bigger than normal, and energy consumption is also higher, electronicly vacuumizes that instrument volume is bigger than normal is inconvenient to carry.
Therefore, need to find that a kind of energy consumption is less to be easy to carry and the outstanding device of vacuumizing effect.
Summary of the invention
The object of this invention is to provide that a kind of energy consumption is less to be easy to carry and the outstanding device of vacuumizing effect.
Technical scheme of the present invention is: jetting stream vacuum machine, form primarily of shell 1 and the fluidic device be placed in shell, shell is provided with switch and power supply/power input interface, whether switch is used for control jet device and works, and described fluidic device mainly comprises the motor 2, booster fan 3 and the ejector 4 that connect successively; Described ejector is the venturi tube structure that large centre, two ends reduces, and the entrance point of ejector seals with the exit end of booster fan 3 and is connected, and be provided with the fixed orifice matched with fluidic device in the enclosure, described fluidic device ejector 4 is placed in fixed orifice; Position narrow between the entrance point of ejector and the exit end hollow be provided with outwardly connects mouth 41, accordingly, be provided with in fixed orifice extend to outside shell with connect that mouth matches connect nozzle aperture, the described mouth that connects is placed in and connects in nozzle aperture; The described mouth that connects is socketed away from the end of ejector and one end of a flexible pipe 42, and the other end of flexible pipe is connected with interface 43, and the one-way exhaust valve on described interface and sealing bag matches, and interface screws fastening on one-way exhaust valve; Casing wall around booster fan is provided with ventilation inlet; After opening switch, motor operations, is driven booster fan to rotate, is sucked by the air in the external world by ventilation inlet, the entrance point of ejector is blown into after supercharging, again from the exit end blowout shell of ejector, when air-flow high velocity stream in ejector is out-of-date, negative pressure can be produced at the position that ejector is narrow, simultaneously produce negative pressure connecing in mouth, thus form draught head connecing between mouth and vacuum seal bag, making the air in vacuum seal bag to connecing mouth flowing, entering in ejector along with air-flow flows out shell.
Fluidic device and fixed orifice form negative and positive and coordinate, and the end connecing mouth is given prominence to outside shell.
Beneficial effect
1, form negative pressure by the quick flowing of air-flow in ejector, by negative pressure, the air in sealing bag and steam are siphoned away, make to form vacuum in sealing bag, reduce the boiling point of water, accelerate the water evaporates of article, be sucked out sealing bag, thus achieve quick-drying object;
2, miniaturization low-power consumption and being easy to carry.

Detailed description of the invention
As shown in Fig. 1 to Fig. 3, jetting stream vacuum machine, form primarily of shell 1 and the fluidic device be placed in shell, shell is provided with switch and power supply/power input interface, whether switch is used for control jet device and works, 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 reduces, the entrance point of ejector seals with the exit end of booster fan 3 and is connected, and be provided with the fixed orifice matched with fluidic device in the enclosure, described fluidic device ejector 4 is placed in fixed orifice; Position narrow between the entrance point of ejector and the exit end hollow be provided with outwardly connects mouth 41, accordingly, be provided with in fixed orifice extend to outside shell with connect that mouth matches connect nozzle aperture, the described mouth that connects is placed in and connects in nozzle aperture; The described mouth that connects is socketed away from the end of ejector and one end of a flexible pipe 42, and the other end of flexible pipe is connected with interface 43.When needing to use just by flexible pipe and interface with connect mouth and be connected, when not using, flexible pipe and interface being taken off from connecing mouth, conveniently depositing.
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; Casing wall around booster fan is provided with ventilation inlet; After opening switch, motor operations, is driven booster fan to rotate, is sucked by the air in the external world by ventilation inlet, the entrance point of ejector is blown into after supercharging, again from the exit end blowout shell of ejector, when air-flow high velocity stream in ejector is out-of-date, negative pressure can be produced at the position that ejector is narrow, simultaneously produce negative pressure connecing in mouth, thus form draught head connecing between mouth and vacuum seal bag, making the air in vacuum seal bag to connecing mouth flowing, entering in ejector along with air-flow flows out shell.
Fluidic device and fixed orifice form negative and positive and coordinate, and the end connecing mouth is given prominence to outside shell.
It is directly realized from sealing bag suck by booster fan mostly that vacuum seal bag vacuumizes, the present invention is when air-flow being blown over ejector by booster fan, produces powerful negative pressure to siphon away air in vacuum seal bag and steam in the position that ejector is narrow.
If settle in vacuum seal bag and need dry clothing, according to the boiling point principle of water, when a barometric pressure, the boiling point of water is close to 100 degrees Celsius, under equal ambient temperature, when air pressure diminishes, the boiling point of water also can reduce accordingly, the boiling point of water reduces, 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, be discharged in outside air by the steam that is evaporated after connecing mouth and being sucked into ejector, therefore, clothing also just can be dry rapidly.
Same, in vacuum seal bag, settle other article, also by the principle of work of ejector, sealing bag can be vacuumized.
Above-described embodiment is only used to interpretation purposes of the present invention, and is not limitation of the present invention, those skilled in the art, in essential scope of the present invention, makes a variety of changes or substitutes, also should belong to protection category of the present invention.
