Description
Technical field
The utility model relates to the Bioexperiment equipment technical field, specifically a kind of positive negative pressure Bioexperiment operation cabinet.
Background technology
The Bioexperiment goods have the characteristics of the various bacteria of carrying, mould and microorganism; therefore it must be inserted in the Bioexperiment equipment and operate; prevent exposing of harmful substance with this and pollute working environment in the laboratory, effectively protect health of operators.At present, Bioexperiment equipment of a great variety mostly only has single function, and its operating space can only produce a kind of pressure environment, i.e. malleation working environment or negative pressure working environment.But some Bioexperiment goods is because of due to its character, and it both need be handled under the malleation working environment, need handle under the negative pressure working environment again, and some also must carry out repeatedly repeatedly.For this reason, operating personnel carry out the malleation processing with the Bioexperiment goods in being the Bioexperiment equipment of malleation duty after, the Bioexperiment goods need be taken out in this equipment, and insert and carry out negative pressure again in the other Bioexperiment equipment that is the negative pressure duty and handle, the shortcoming of its existence is as follows: one, the Bioexperiment goods are after taking out in the equipment that is the malleation duty, insert the equipment that is the negative pressure duty again, this process is the process that exposes of Bioexperiment goods harmful substance, it not only pollutes the working environment in the laboratory easily, health to operating personnel causes infringement easily, and can greatly reduce the success rate of experiment; Two, the Bioexperiment goods are after the malleation experimental facilities is handled, it is transformed in another negative pressure experimental facilities again and handles, some also must carry out repeatedly repeatedly, it makes that not only operational sequence is too loaded down with trivial details, operating personnel are wasted time and energy, and has caused the low drawback of Bioexperiment goods output efficiency.Thus, many worries have been brought to every aspect.
Summary of the invention
The purpose of this utility model provides a kind of positive negative pressure Bioexperiment operation cabinet, it can solve function singleness, the experiment quality of prior art existence and output efficiency is lower, operation is wasted time and energy, and causes the Bioexperiment goods to the working environment pollution problems easily.
The purpose of this utility model is achieved through the following technical solutions: positive negative pressure Bioexperiment operation cabinet, it comprises cabinet, controller, be respectively equipped with blower fan on the cabinet, filter, even wind net, operation room and table top, the cabinet side is connected with and the cabinet shape, construct the second identical cabinet, be respectively equipped with and blower fan on second cabinet, filter, even wind net, second blower fan that operation room and table top are corresponding mutually, second filter, the second even wind net, second operation room and second table top, the cabinet and second cabinet have space bar each other, offer the transmission window on the space bar, transmit window and communicate with the operation room and second operation room respectively, transmit the left window that is hinged on the window left port, right window is hinged on the right output port; Combining glass is installed in the middle and upper part in the operation room and the second operation room front; Controller is connected with the blower fan and second blower fan respectively by lead.
For further realizing the purpose of this utility model, also can finish by the following technical programs: described transmission window is a rectangular tubular, has between its left port and the right output port at interval, and this length at interval is greater than the thickness of space bar.Transmit that the window left port is corresponding with table top top, right output port and the second table top top is corresponding.
The beneficial effect that the utility model can produce: because of the cabinet side is provided with second cabinet, blower fan on the cabinet is set at and is rotated in the forward, make and be the malleation duty in the cabinet, blower fan on second cabinet is set at reverse rotation, make and be the negative pressure duty in second cabinet, realized that with this can form the malleation duty on an experimental facilities can form the negative pressure duty again, it can improve output efficiency greatly, alleviates operating personnel's loaded down with trivial details work greatly; Because of cabinet and second cabinet have space bar each other, offer the transmission window on the space bar, transmit window respectively with cabinet on operation room and second operation room on second cabinet communicate, can make the Bioexperiment goods in the malleation duty, can be directly delivered in the negative pressure duty with this, it fundamentally avoided in the easy pollution laboratory working environment, easily operating personnel's health is caused the defective of infringement, and fundamentally guaranteed the experiment quality; Because of transmitting window is rectangular tubular, have between its left port and the right output port at interval, after left window, right window on the transmission window closed, then formed a confined space in the transmission window of rectangular tubulose, the Bioexperiment goods from the malleation duty when the negative pressure duty is transmitted, operating personnel can insert the Bioexperiment goods in this confined space earlier, to avoid the Bioexperiment goods in transmittance process, cause influencing each other of interior malleation of operation room and the two kinds of duties of negative pressure in second operation room.The utility model is simple in structure, multiple functional, easy to operate, time saving and energy saving, and extensive use can produce good social, economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Positive negative pressure Bioexperiment operation cabinet of the present utility model, it comprises cabinet 1, controller 1a, be respectively equipped with blower fan 11 on the cabinet 1, filter 12, even wind net 13, operation room 14 and table top 15, cabinet 1 side is connected with and cabinet 1 shape, construct the second identical cabinet 2, be respectively equipped with and blower fan 11 on second cabinet 2, filter 12, even wind net 13, operation room 14 and the second corresponding mutually blower fan 21 of table top 15, second filter 22, the second even wind net 23, second operation room 24 and second table top 25, the cabinet 1 and second cabinet 2 have space bar 3 each other, offer on the space bar 3 and transmit window 4, transmit window 4 and communicate with the operation room 14 and second operation room 24 respectively, transmit the left window 4a that is hinged on window 4 left port, right window 4b is hinged on the right output port; Combining glass 1b is installed in the middle and upper part in operation room 14 and second operation room, 24 fronts; Controller 1a is connected with the blower fan 11 and second blower fan 21 respectively by lead.Described transmission window 4 is a rectangular tubular, has between its left port and the right output port at interval, and this length at interval is greater than the thickness of space bar 3.Transmit that window 4 left port are corresponding with table top 15 tops, right output port and second table top, 25 tops are corresponding.
