Wind speed is in 3.0m/s to 3.8m/s；
When collected PM2.5 concentration information is greater than preset second threshold, control mainboard is sent to air-blower control box
Third control instruction, so that the revolving speed of air-blower control box control blower, so that the wind speed of air curtain is more than or equal to 3.8m/s.Its
In, first threshold is 50 μ g/m3, second threshold is 100 μ g/m3。
In the present embodiment, according to the PM2.5 levels information of current air mass come, adjust wind speed, thus
Adjust the power of air curtain.When air quality is poor, i.e., number increases and indoor air quality is caused to be deteriorated, by increasing blower wind
Amount is accelerated air flowing, is just discharged after purification.
In the present embodiment, dissipation module 234 is arranged in circulation air path, and dissipation module 234 is successively wrapped from top to bottom
It includes: primary filter screen, high-pressure electrostatic strainer, active carbon filter screen and efficient filter.Dissipation module 234 is to infectiousness such as bacterium, viruses
Microorganism carries out high efficiency filter, disinfection and sterilization, purification, and filtered pure air is discharged by air outlet.
In the present embodiment, bar shaped air outlet 11, which is equipped with, makes the inclined wind-guiding grate of air curtain, and air curtain and air duct groove 14
The angle of normal direction be 20 °.The cold airflow projected by air duct groove 14 can effectively control the exhaled gas of patient
In a zonule behind patient, it is not easy to doctor respiratory region is arrived at, to achieve the purpose that suppress dispersion of pollutants.Doctor
Air-flow around raw is not directly affected by air curtain, Thermal plume energy normal development.Such case can preferably obstruct patient and
Air-flow interaction between doctor, can reduce the aerosol infection risk in actual environment.20 ° of air-supply air-flows have one towards trouble
The inclined acting surface in person direction has better suppression to the exhaled gas of patient, pollutant is blowed to the sky behind patient
Between.However, it is desirable to which, it is emphasized that it is only most preferred angle, positive and negative 5 ° of effects achieved that wind direction, which is designed as 20 °,
Although being lacking, still satisfy the use demand.
In the present embodiment, diagnosis and treatment bench can also include sales counter 12, touch screen 4.Touch screen 4 is electrically connected with control mainboard.
Touch screen 4 is set to side of the air box 23 towards doctor.Doctor can issue control mainboard by touch screen 4 and instruct, then by
Control mainboard manipulates blower, realizes the functions such as start and stop, timing, the gear adjusting of blower.
Therefore the isolation diagnostic table provided in an embodiment of the present invention based on air curtain isolation, including control mainboard, top cover
21, two air boxes 23, work top 13 and support frame 22.Wherein, 21, two shapes between air box 23 and support frame 22 of top cover
At circulation air path, the setting of work top 13 is provided with item between two air boxes 23 and support frame 22, and on work top 13
Shape air outlet 14 realizes the gas for breathing out patient so that the wind of circulation air path forms air curtain after bar shaped air outlet 14
It is converted into the function of partition air curtain.And the PM2.5 concentration information in sensor acquisition present air, and will be collected
PM2.5 concentration information is sent to control mainboard, so that control mainboard sends control instruction to air-blower control box, to pass through adjusting
The revolving speed of blower, adjust air curtain goes out wind velocity.The output of each blower of manual adjustment, skill of the present invention are needed compared with the prior art
Art scheme can realize the automatic control of air curtain according to current air mass, and isolation effect is improved when number increases, is subtracted in number
It is adjustable blower air output when few, realizes energy conservation and environmental protection.
Further, bar shaped air outlet 14 is special designing certain angle (20 degree of inclination), and the wind of discharge will form together
The clean air curtain tilted upward blows to patient direction, and the air curtain with certain speed can obstruct the aerosol of patient's exhalation, just as
It is one of invisible wall, outside aerosol gear, while protecting doctor, avoids the air to carry the germs of a disease and passed to surrounding
It broadcasts, preferably reduces the probability for generating cross-infection, there is optimal partition effect.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
