Abstract

A sealing bag vacuumizer is mainly composed of an outer shell and a jet flow device inside the outer shell. A switch and a power source/power source input connector are arranged on the outer shell. The switch is used for controlling whether the jet flow device works or not. The jet flow device mainly comprises a motor, a booster fan and a jet device which are sequentially connected. Negative pressure is formed through rapid flowing of airflow in the jet device, air and water vapor in sealing bags are sucked away through negative pressure, the interiors of the sealing bags form vacuum, the boiling point of water is reduced, evaporation of water of objects is accelerated, water of objects is sucked out of the sealing bags, and therefore the rapid drying purpose is achieved.

Description

Sealing bag evacuator

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

Technical scheme of the present invention is: sealing bag evacuator, 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, the entrance point of ejector 4 seals with the exit end of booster fan 3 and is connected, the exit end of ejector is positioned at the outer wall of shell, be provided with at entrance point and the position narrow between exit end of ejector outwardly communicate with ejector bore passages connect mouth 41, the described mouth that connects is socketed away from the end of ejector and one end of a flexible pipe 42, the other end of flexible pipe is connected with interface 43, 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 and steam to connecing mouth flowing, entering in ejector along with air-flow flows out shell.

Locating plate 11 and bracing frame 12 is provided with in described shell, space is left between described locating plate and bracing frame, 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 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, sealing bag evacuator, 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 4 seals with the exit end of booster fan 3 and is connected, the exit end of ejector is positioned at the outer wall of shell, be provided with at entrance point and the position narrow between exit end of ejector outwardly communicate with ejector bore passages connect mouth 41, 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 and steam to connecing mouth flowing, entering in ejector along with air-flow flows out 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.
