Description

Technical Field

[0001] This utility model relates to the field of planktonic microbial sampling technology, specifically a height-adjustable planktonic microbial sampler. Background Technology

[0002] A planktonic microbial sampler is an instrument specifically designed for collecting and studying planktonic microorganisms. Specifically, the sampler, through a specific design, allows water or air to pass through a sampling head at a certain velocity. Planktonic microorganisms are captured after impacting the sampling medium (such as a filter membrane or culture medium). For airborne planktonic microorganisms (dust bacteria), the sampler employs a porous suction design. As air passes through the porous sampling head, airborne microorganisms are impacted onto the culture medium (such as agar medium) and thus captured. Under suitable temperature and humidity conditions, these microorganisms will grow and multiply on the culture medium, forming visible colonies.

[0003] Existing samplers cannot adjust their height. For scenarios requiring sampling at different heights, non-adjustable samplers may require other methods to adjust the sampling position, which increases the complexity and time cost of operation. Therefore, we propose a height-adjustable planktonic microorganism sampler to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a height-adjustable planktonic microorganism sampler to solve the problem mentioned in the background art that existing samplers cannot adjust their height. For scenarios where sampling is required at different heights, non-adjustable samplers may need to adjust the sampling position through other means, which increases the complexity of operation and time cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable planktonic microorganism sampler, comprising a base and a sampling pump base, wherein the sampling pump base is located above the base;

[0006] Also includes:

[0007] A handle is connected between a base and a sampling pump base, with the bottom end of the handle fixed to the base by welding. The handle has an integrally formed through-groove. A connecting frame is located at the rear end of the sampling pump base, and the connecting frame is movably engaged within the through-groove. Several evenly distributed limiting grooves are provided on the outer surface of the handle, located on both sides of the through-groove. A fixing frame is located at the rear end of the connecting frame, and a main limiting rod is located at the rear end of the fixing frame, and the main limiting rod is movably engaged within the limiting groove. A control panel is located on the upper surface of the base. A sampling port is located at the bottom of the sampling pump base, and a fan is located at the upper end of the sampling pump base.

[0008] Preferably, the outer sides of the handle are symmetrically provided with sliding grooves, and the sliding grooves are connected to the through grooves. The rear sides of the connecting frame are symmetrically provided with sliding rods, and the sliding rods are slidably engaged inside the sliding grooves.

[0009] Preferably, a connecting plate is provided on the rear side of the main limiting rod, and a secondary limiting rod is provided on the rear side of the connecting plate, and the secondary limiting rod is movably engaged inside the limiting groove.

[0010] Preferably, the rear end of the sampling pump base is provided with a locking frame, and the connecting frame and the locking frame are hinged together.

[0011] Preferably, the bottom of the sampling pump base is provided with a bottom cover, which is opened and closed by a connector, and the bottom cover is magnetically connected to the bottom of the sampling pump base.

[0012] Preferably, the bottom of the base is provided with an anti-slip pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting a through groove inside the handle and a connecting frame at the rear end of the sampling pump base, the sampling pump base can be height adjusted on the surface of the handle through the connecting frame and the through groove. A limiting groove is set on the outside of the handle and a limiting rod is set at the rear end of the connecting frame. The limiting rod engages in the limiting groove, which limits the position of the sampling pump base after adjustment. Under the action of gravity, the limiting rod is tightly engaged in the limiting groove. Furthermore, two sets of limiting rods, main and auxiliary, are set to further improve the stability of engagement and prevent the limiting rod from loosening and falling off, causing the sampling pump base to slip off.
