Description
Technical field
Patent of the present invention belongs to biological plant technical field, more particularly to a kind of Biohazard Safety Equipment with warning function.
Background technology
When Biohazard Safety Equipment is to operate primary culture, bacterium strain and diagnostic sample etc. with infective experiment material; for protecting operator, laboratory environment and experiment material, it is set to avoid exposure to issuable infectious aerosol and spatters during aforesaid operations and design.Biohazard Safety Equipment is widely used in health care, disease prevention and control, food hygiene, bio-pharmaceuticals, and the field such as environmental monitoring and different kind organism laboratory is the important foundation for ensureing bio-safety and Environmental security.
Existing Biohazard Safety Equipment can be realized being controlled the air inside cabinet, but can not at any time monitor the working condition of Biohazard Safety Equipment, and the error that prompting operating personnel occur in operational procedure.The warning device that existing Biohazard Safety Equipment has, it is most of to use sound and light alarm, it is impossible to the reason for content of enough display alarm and appearance are alarmed and the deviation for eliminating alarm.
Patent of invention content
In order to solve the above problems, patent of the present invention carried it is a kind of the working condition of Biohazard Safety Equipment can be monitored, and to deviateing the Biohazard Safety Equipment with warning function alarmed of carrying out of normal operating conditions.
It is that, up to above-mentioned purpose, the technical scheme that patent of the present invention is used is：A kind of Biohazard Safety Equipment with warning function, including work top and cabinet are provided, the cabinet top is provided with air outlet and humiture detector, and inwall is provided with negative pressure detector and thresholding detector；The work top is provided with air inlet, and air outlet and air inlet are connected with air cleaner, and air cleaner both sides are provided with air pressure detector；The humiture detector, negative pressure detector, thresholding detector and air pressure detector are connected with central processing system, and central processing system is connected with alarm.
Preferably, air inlet is arranged at four ends angle of work top.
Preferably, cabinet is provided with display screen, and central processing system is connected with display screen
Patent of the present invention has the advantages that：
Multiple detectors are provided with Biohazard Safety Equipment, the state of the switch door state of Biohazard Safety Equipment, stream condition, atmospheric pressure state and air cleaner can be monitored, when there is abnormal state and alarm；Cabinet is provided with display screen, is capable of the content of display alarm and the deviant of state.

In figure：1st, work top；2nd, cabinet；3rd, air outlet；4th, air inlet；5th, humiture detector；6th, thresholding detector；7th, air cleaner；8th, negative pressure detector；9th, display screen；10th, alarm.
Specific embodiment
Patent of the present invention is described further below in conjunction with the accompanying drawings.
Embodiment
Patent of the present invention provides a kind of Biohazard Safety Equipment with warning function, as shown in figure 1, including work top 1 and cabinet 2, the top of cabinet 2 is provided with air outlet 3 and humiture detector 5, inwall is provided with negative pressure detector 8 and thresholding detector 6；The work top 1 is provided with air inlet 4, and air outlet 3 and air inlet 4 are connected with air cleaner 7, and the both sides of air cleaner 7 are provided with air pressure detector；The humiture detector 5, negative pressure detector 8, thresholding detector 8 and air pressure detector are connected with central processing system, and central processing system is connected with alarm 10.
Air outlet 3 on cabinet 2 is connected with air cleaner 7, and be passed through the air after purification inside cabinet 2 by air outlet 3.Air inlet 4 is connected with air cleaner 7, by the purification of air in cabinet 2, according to prior art, the air of air inlet 4 can exclude cabinet 2 and air is passed through after purifying again, the air cleaner 7 that can also be connected with air outlet 3 is connected, and cabinet 2 is passed through after passing air through filtering twice.There are air inlet and gas outlet in the two ends of air cleaner 7, and air pressure detector is installed at air inlet and gas outlet, monitor the air pressure change of both sides.If the filter membrane of air cleaner 7 is damaged or blocked, air pressure detector reacts to central processing system data, and alarm is judged after contrasting computing.
As shown in Fig. 2 the signal transmission that the humiture detector 5 of Biohazard Safety Equipment, negative pressure detector 8, air pressure detector and thresholding detector 6 will be collected is to central processing system, by the computing of central processing system, alarm 10 is driven to alarm after meeting alert if.Humiture detector 5 is used to detect the humiture inside cabinet 2 that negative pressure detector 8 to be used to monitor the pressure difference of cabinet 2 and the external world, it is ensured that the inside of cabinet 2 keeps certain Negative Pressure Difference, and Negative Pressure Difference to reduce or alarmed more than after default value.Preceding door and window is mounted on cabinet 2, preceding door and window is provided with dodge gate.In practical operation, the switching value of dodge gate will influence the air flow in cabinet 2, when switching value is larger, can make the air turbulence inside cabinet 2.Air flow demand advection inside cabinet 2, should try one's best reduction sinuous flow and vortex.Operating personnel are when dodge gate is opened, it is impossible to effective controlling switch amount, and usage threshold detector 6 is monitored to the position of the switch of dodge gate, when the switching value of dodge gate reaches a certain position, will trigger threshold controller 6, alarm 10 is alarmed.
Further, air inlet 4 is arranged at four ends angle of work top 1.
Further, cabinet 2 is provided with display screen 9, and central processing system is connected with display screen 9, warning message is reacted on display screen 9, and operating personnel being capable of failure judgement type in time, in time treatment.
Using technical solutions according to the invention, or those skilled in the art is under the inspiration of inventive technique scheme, designs similar technical scheme, and reaches above-mentioned technique effect, is to fall into protection scope of the present invention.
