[0003] However, the size and power of the existing air planktonic bacteria sampler are relatively small. To meet the requirement of air impact velocity of 10.8m / s, the fan motor is required to operate under a large load. Long-term use will accelerate the damage of the fan motor and reduce the fan motor. The service life of the sampler is also greatly reduced

The invention relates to an air bacterioplankton sampling device. The air bacteriaplankton sampling device comprises a shell, wherein a sampling head is arranged inside the shell, a culture dish tray is arranged below the sampling head, an air inlet is formed in the sampling head, an air outlet is formed in the bottom of the shell, an exhaust opening is formed below the culture dish tray, an exhaust cavity is arranged below the exhaust opening, a motor drive fan structure is arranged in the exhaust cavity, the fan structure comprises a fixed framework, the fixed framework is provided with at least two fans, a fan shaft is fixedly provided with a small gear, a motor is arranged below the fixed framework, a shaft of the motor is provided with a large gar, and the large gear is engaged with the small gear. By adopting the structure, a plurality of fans are electrically driven by the motor, so that the needed collision speed of the motor can be achieved under the circumstance of low rotation speed, the damage to the motor can be avoided, the structure is simple, and the use is convenient.
Description
technical field [0001] The invention relates to a device in the technical field of detection instruments, in particular to an air floating bacteria sampler. Background technique [0002] The Air Planktonic Bacteria Sampler is a high-efficiency porous suction sampler, which is based on the Anderson impact principle. The suction device of the instrument sucks air through the porous sampling head and hits the petri dish, and the microorganisms in the air are "captured" On agar medium, it is used in various industries and departments. [0003] However, the volume and power of the existing air planktonic bacteria sampler are relatively small. To meet the requirement of the air impact velocity of 10.8m / s, the fan motor is required to operate under a heavy load. Long-term use will accelerate the damage of the fan motor and reduce the fan motor. The service life of the sampler is also greatly reduced. Contents of the invention [0004] The technical problem to be solved by the p...
