Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, a bacteria collector for preventive medical personnel comprises a bacteria collecting barrel 1; the upper end of the bacteria collecting cylinder 1 is in threaded sleeve connection with an upper end cover 2, and the lower end of the bacteria collecting cylinder is in threaded sleeve connection with a lower end cover 3; a baffle ring 4 is coaxially sleeved and fixed at the upper part in the bacteria collecting barrel 1; the left side of the upper end cover 2 is fixedly communicated with a liquid injection pipe 5; the upper end of the liquid injection pipe 5 is fixedly communicated with a water collecting funnel 6; the middle part of the lower end cover 3 is fixedly communicated with a liquid discharge pipe 7; a collecting device is arranged in the bacteria collecting cylinder 1; the collecting device comprises a funnel-shaped supporting frame 8 arranged in the bacteria collecting cylinder 1; the supporting frame 8 consists of a connecting ring 9 at the upper part and a plurality of inclined supporting rods 10 at the lower part; the inclined support rods 10 are uniformly distributed below the connecting ring 9 along the circumferential direction; the lower ends of the inclined stay bars 10 are fixedly connected with each other; the upper ends of the inclined stay bars 10 are all fixed at the lower end of the connecting ring 9; the connecting ring 9 is coaxially sleeved in the bacteria collecting barrel 1 in a matching way; the connecting ring 9 is arranged at the upper end of the baffle ring 4; a funnel-shaped bacteria collecting net 11 is matched and bonded in the support frame 8; a rotating rod 12 is coaxially arranged in the support frame 8; the lower end of the rotary rod 12 penetrates through the bacteria collecting net 11 and is fixed with the inner lower end of the support frame 8; the upper end of the rotary rod 12 penetrates through the middle part of the upper end cover 2; the lower end of the liquid injection pipe 5 penetrates through the upper end cover 2 and extends into the inner side of the connecting ring 9; the liquid injection pipe 5 is provided with a flow valve 13; a stop block 14 is sleeved on the upper part of the rotating rod 12; the stop 14 is connected to the lever 12 by a transverse through-bolt 15.

Firstly, water sample is collected by the water collecting funnel 6 and flows out of the liquid injection pipe 5, then is received and filtered by the bacteria collecting net 11 positioned below the liquid injection pipe 5, in the process, the part of the bacteria collecting net 11 which is positioned right below the liquid injection pipe 5 mainly plays a role in filtering, bacteria are gradually collected on the part of the bacteria collecting net 11, after a period of time, the rotary rod 12 is rotated to enable the support frame 8 to rotate, the water bearing range of the bacteria collecting net 11 can be adjusted, thereby avoiding the problem that the same position on the bacteria collecting net 11 is always washed by water flow, reducing bacteria lost by water flow washing, improving the bacteria collecting rate, compared with the traditional bacteria collection mode, the water sample with the same quantity can leave more bacteria by the mode of the technical scheme, especially under the condition that the water sample is limited, it is necessary to improve the bacteria collection rate, and the risk of detection errors can be greatly reduced.

The problem of water flow splashing caused by the fact that the support frame 8 shakes up and down can be avoided by the blocking of the stop block 14 and the blocking ring 4, the stop block 14 is connected with the rotary rod 12 through the transverse through bolt 15, the stop block 14 can be detached, and the bacterium collecting net 11 can be conveniently taken down and replaced; the flow valve 13 can control the flow rate of water injected from the injection pipe 5, and actually the smaller the flow rate of water injected is, the less bacteria are taken away by the water flow (the bacteria collecting net 11 cannot block all bacteria), but at the same time, the time is longer, so that the flow rate can be set according to the needs during operation, for example, in the case of a small water sample, the flow rate needs to be reduced to improve the bacteria collecting rate, and in the case of a large water sample, the flow rate can be increased to reduce the time consumed.
