Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of improved microorganism sampler is provided, realize that operator separate with testing environment, thus avoid operator to the interference of testing environment and hostile environment to health effects.
For solving above technical problem, the utility model is taked following technical scheme: a kind of microorganism sampler, comprise collecting unit and control unit, wherein said collecting unit comprises the sampling head with acquisition port and slit, be arranged on the culture dish of acquisition port below, be used to support the culture dish support and the base of culture dish, the bottom of base is connected with blower fan by tracheae, described control unit comprises controller, display screen, be arranged on the operating key that can be used in the control sampling on the controller panel, wherein: controller and sampling head split are provided with, described control unit also comprises the telepilot that separates setting with controller, and described telepilot is used at a distance sampling being controlled.
The setting of described telepilot can be implemented with reference to existing telecontrol engineering.
According to further embodiment of the present utility model: described slit has a plurality of, and a plurality of slit is along the circumferential uniform distribution of described acquisition port.Preferably, described acquisition port is circular, and each described slit is along the radially extension of acquisition port.Upstream at described each slit also is provided with the buffering ramp pan, and the design of described sampling head meets the following conditions:
Wherein:S
Slit The total area of representing described a plurality of slits; B represents slit width; L represents slit length; T represents slot number;S
Always The top surface area of expression acquisition port;V
Bump The expression microorganism strikes the speed that culture dish needs;V
Sampling Expression sampling flow velocity.
Above-mentioned buffering ramp pan is tubaeform that the direction towards described slit narrows down gradually from the upper surface of acquisition port.
Take above-mentioned sampling head design, can realize the isokinetic sampling, sampling is direct, and the wind speed of acquisition port and clean indoor air velocity keep basically identical, can accurately reflect the concentration of microorganism in the clean room.During sampling, band puffball air is evenly impinged upon the agar surface in the culture dish at a high speed by a plurality of slits, the sampling head design optimization stroke speed, guaranteed biology efficient.Improved the collecting efficiency of the active particle that meets the ISO14698-1 standard; Whether in addition, taking this sampling head can also be easy to pick out is effective microbe, and only the microorganism at the slit location place is effectively, and all the other are local, and then explanation does not collect in gatherer process if there is microorganism to exist, for artificial the interference causes.
According to the utility model, the material of sampling head, base and controller all is preferably the 316L stainless steel, meets clean environment and uses standard.Preferably, described tracheae is the expansion pipe of vary in length, and so, tracheae can extend or shorten according to the actual measurement environment.
Owing to adopt the enforcement of above technical scheme, the utility model compared with prior art has following advantage: the controller of microorganism sampler of the present utility model and sampling head split are provided with, also can utilize telepilot to carry out the long-distance remote control sampling, can realize separating of operator and testing environment, avoid operator to the interference of testing environment and hostile environment to health effects.
