Specific embodiment
Embodiment 1: convenient, accurate, the reliable and inexpensive control in order to solve electrospinning fibre injection ambient temperature and humidity,
The present embodiment provides a kind of combined type electrospinning fiber jet environment control unit based on controllable air flow, the device is by constant temperature and humidity
Gas source, bracket, blowing slot, air draught slot, strainer, suction fan composition.
Wherein: the constant temperature and humidity gas source can export the adjustable air of temperature and humidity outward, and air mass flow is controllable, and constant temperature is permanent
Moisture source is the common device of automation control area.
The blowing slot is connected by above-mentioned constant temperature and humidity gas source with four blowing slots, and blowing slot controls air-flow with certain angle
Degree is blown downwards, and four blowing slots are mounted on the second level support arm of four support arms of bracket by card slot, four blowing slot head
Tail is connected.Blowing slot can be installed with rectangle wind groove according to actual needs, form the air curtain of a rectangle；The outside of blowing slot is equipped with
Crispation type curtain can pull downward on curtain in four direction and one is articulated on air draught slot, be formed close in physical significance
Space is closed so that the obturation effect of blowing slot and air draught slot is more preferable.Four blowing slots one of those be equipped with cross blowing mouth and be used to
Air curtain is formed on the top in space, wherein the wind that lateral air outlet comes out can only be stopped by tiny syringe needle, it will not be to whole wind
It is significantly interfered with to generation.Blowing slot on lateral air outlet opposite pastes folding 90 angle line type of lightweight by internal layer lower position
Hinge, so that most of wind of lateral air curtain exports above device, only a small amount of beam wind can be flowed into jet space, but
Will not injection track to electrospinning fibre generate interference.The gas outlet width of the blowing slot in five directions is manually adjustable；Gas source
When flow is constant, air outlet width is smaller, and wind speed is bigger, and the air curtain deformation of formation is smaller.The bracket is aluminum alloy materials
It is made, is made of interior diameter ring, one level of support arm and second level support arm.The length of the adjustable interior diameter of bracket is so as to fixation
On the electrospun solution container of different size；The length of the four direction support arm of bracket can be by adjusting second level support arm
Extension elongation is adjusted, and adapts to the blowing slot of different length.
The air draught slot is to inhale to form stable space wind field in the rectangle that the surrounding of electrospinning fibre collecting board is installed
Wind groove；Electrospinning fibre is influenced when spraying by many kinds of parameters, is had small part fiber and is sprayed control area, therefore in air draught slot
Side is equipped with the baffle of adjustable-angle, the winged electrospinning fibre of spray is collected, to form regular, controllable electrospinning fibre on collecting board
Shape.
The strainer belongs to replaceable consumptive material, and strainer is mounted among suction fan and air draught slot, for filtering out injection
Electrospinning fibre impurity in air draught slot.The suction fan provides air-breathing power for air draught slot.
By above-mentioned, combined type electrospinning fiber jet environment control unit described in the present embodiment based on controllable air flow, by
Constant temperature and humidity gas source, bracket, blowing slot, air draught slot, strainer, suction fan composition.The device produces attached as electrospinning fibre
It is not limited by a space, when belonging to device application not by electrospinning Effect of Materials, can be various types of electrospinnings by simply installing
Equipment provides reliable, convenient and fast temperature and humidity environmental Kuznets Curves.
In the embodiment, the user of the combined type electrospinning fiber jet environment control unit based on controllable air flow is provided
Method:
The length that demand adjusts bracket support arm is sprayed according to electrospinning fibre first, i.e. second level support arm stretches out one level of support
The length of arm selects corresponding blowing slot according to the length of support arm, so that it is determined that the length and width of rectangular space；Second level support arm
Forward direction and laterally be equipped with card slot, for fixing blowing slot；Then wind groove is fixed in the card slot of second level support arm, is determined each
A blowing slot ending connects；Then the interior diameter that bracket is adjusted according to the outer dia of electrospun solution external container, according to electrospinning
Injection demand determines the height of bracket, then bracket is fixed on to the corresponding position of external container together together with blowing slot.Manually
Adjust blowing slot lower section and lateral air outlet size and angle；It is equipped with curtain of crispaturaing in the outside of blowing slot, when to electrospinning fibre
Airtight space when requiring tighter, curtain can be pulled down, in the exterior snap for hanging over air draught slot, i.e., by blowing slot air curtain and
Roller shutter forms two seals face.
Four blowing slots are connected with constant temperature and humidity gas source with gas-guide tube.Constant temperature and humidity gas source can freely set guiding blowing
The temperature and humidity and flow of the air of slot.Collecting board surrounding in lower section is equipped with air draught slot, and each air draught slot ending is connected, and with blow
Wind groove forms corresponding relationship up and down.Electrospinning fibre has small part fiber and sprays control area when spraying, so in air draught slot
Inside is equipped with the baffle of adjustable angle, collects the winged electrospinning fibre of spray, while regular, controllable electricity can be also formed on collecting board
Spin fiber shape；Aspiration motor is connect by replaceable strainer with four air draught slots, can by adjusting the revolving speed of aspiration motor
Air draught slot is set to generate different inspiratory capacities.It tests in laboratory conditions, the air-breathing of the gas output of air inlet motor than aspiration motor
When amount mostly 20%, more efficiently confined space effect can be formed.
Embodiment 2: a kind of combined type electrospinning fiber jet environment control unit based on controllable air flow, including blowing slot,
Air draught slot, the blowing slot are enclose and hollow support frame, and the hollow layer of the blowing slot is connected to constant temperature and humidity
For hair dryer with the hollow layer air inlet to blowing slot, the side wall of support frame forms the guiding device of air curtain as air inlet, described
Blowing slot is correspondingly arranged air draught slot, and the air draught slot is enclose and hollow support frame, and hollow layer is connected to suction fan,
The air curtain that the blowing slot is formed is by air draught slot by suction fan outlet.It is empty between formation blowing slot and air draught slot by above-mentioned
The air curtain of flow of air, so that environment is sprayed to be formed close to confined space, and air curtain is formed as constant temperature, constant humidity, so that this is close
Closed loop border is constant temperature, constant humidity environment, to construct the closed permanent epidemic disaster space of collaboration.
As shown in figure 4, in one embodiment, the inner sidewall of the blowing slot is by bracket connection interior diameter ring with fixation
Electrospinning fibre injection apparatus forms interior diameter ring and electrospinning fibre injection apparatus and is tightly connected, and, the sections inner side of blowing slot
Wall outputs cross blowing mouth, and the cross blowing mouth releases can be covered in the air curtain that support frame encloses plane substantially.In the reality
