Abstract

The invention relates to a sampling device capable of controlling planktonic bacteria automatically. The device comprises a shell, a sampling head is arranged inside the shell, a culture dish tray is arranged under the sampling head, an air inlet is formed in the sampling head, an air outlet is formed in the bottom of the shell, a suction opening is formed in the bottom of the culture dish tray, a draft fan is arranged below the suction opening, an air speed inductor is arranged at the suction opening, a control chip is arranged on the shell, the air speed inductor is connected with the connect chip, and a rotating speed inductor is arranged on a draft fan shaft and connected with the control chip. By the adoption of the structure, the draft fan is controlled through the control chip, exact values of air speed are inducted through the air speed inductor before the control is conducted, the structure is simple, no sampling error occurs in the application process, the automatic air speed adjusting function is achieved, the rotating speed of the draft fan is inducted through the rotating speed inductor, and it is guaranteed that the rotating speed of the draft fan is maintained within the healthy range.

Description

technical field [0001] The invention relates to a device in the technical field of detection instruments, in particular to an automatic control planktonic 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] At present, when using the air planktonic bacteria sampler, due to various reasons, the resistance in the entire air path changes, and the speed of the fan rotation changes, which may lead to failure to meet the impact standard, resulting in errors in the actual sampling of the instrument. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an automatic control pla...
