Pump, the second port 2132 of gas passage 213 are led between shell 21 and filter mantle 23.An air guide is equipped in gas passage 213
Pipe 50, gas-guide tube 50 have the first port and second port 51 at the both ends for being located at gas-guide tube, the first end of gas-guide tube 50
Mouth leads to air pump, the opening side of the second port 2132 of the opening direction and gas passage 213 of the second port 51 of gas-guide tube 50
To vertical.
First port 2131 of the first port of gas-guide tube 50 close to gas passage 213, the second port 51 of gas-guide tube 50
Close to the second port 2132 of gas passage 213.
Upward, the second port 51 of gas-guide tube 50 is set to gas-guide tube 50 to the second port 2132 of gas passage 213
Side wall.Gas-guide tube 50 is tubular construction open at one end, and the second port 51 of gas-guide tube 50 is the side wall set on gas-guide tube 50
Multiple ventholes 52.Multiple ventholes 52 are respectively arranged on the opposite two sides of gas-guide tube 50.
The first port 2131 of gas passage 213 is set to the bottom of sample receiving portion 20, the second port of gas passage 213
2132 are set to the top of sample receiving portion 20.
Gas-guide tube 50 is inserted into from the first port 2131 of gas passage 213.
As shown in figure 4, the first port of gas-guide tube 50 is additionally provided with the protruding portion 53 projected radially outwardly, protruding portion 53 is under
Side is connected to the outer edge of the first port 2131 of gas passage 213.It is prominent when sample receiving portion 20 is installed on pedestal 30
Portion 53 is sandwiched between sample receiving portion 20 and pedestal 30, to guarantee that 50 position of gas-guide tube is fixed.As shown in figure 5, protruding portion 53
On be additionally provided with a positioning region, the second port 2132 of gas passage 213 is correspondingly provided with auxiliary section, and positioning region connects with auxiliary section
It closes to realize positioning.In the present embodiment, positioning region is a protrusion, and auxiliary section is the recess for being adapted to the protrusion.It is of course also possible to
Positioning region and auxiliary section are used as using the structure that other are matched.The peripheral surface of gas-guide tube 50 is equipped with a groove 55, this is recessed
Slot 55 is for being arranged sealing ring 60.As shown in figure 3, sealing ring 60 is set in the groove 55, when gas-guide tube 50 is inserted into gas passage
When 213, sealing ring seals the gap between gas-guide tube 50 and gas passage 213, so that it is guaranteed that the liquid in sample receiving portion 20
Pedestal 30 will not be entered, damage the electrical equipment in pedestal 30.
Pedestal 30 is equipped with blow vent (not shown), and blow vent is connected to air pump, the first port alignment of gas-guide tube 50
Blow vent.
Shell 21 includes ontology 211 and outer cover 212, and outer cover 212 is placed in the opening of ontology 211, and filter mantle 23 is tubular
Structure, the lower end of filter mantle 23 are reticular part 232, and the upper end of filter mantle 23 is plate-like portion 231, and reticular part 232 is for filtering, plate
Shape portion 231 has fluid tight, and for plate-like portion 231 relative to reticular part 232 closer to outer cover 212, sample export 25 faces reticular part
232, the second port 2132 of gas passage 213 is between plate-like portion 231 and ontology 211.In this way, splash in filter mantle 23
Liquid is blocked by plate-like portion 231 and is not easy to fall into second port, damages air pump.Plate-like portion 231 is horn-like structure, plate-like portion
231 gradually restrain downward, and the upper end-face edge of plate-like portion 231 abuts outer cover 212.The lower edge of reticular part 232 abuts ontology 211
Bottom surface.The inside of outer cover 212 is equipped with an elastomeric pad 22, and elastomeric pad 22 is set to the upper end-face edge and outer cover of plate-like portion 231
Between 212.When on the lid to ontology 211 of outer cover 212, object to be detected can be limited in filter mantle 23, without by appointing
What gap flows directly to sample export 25, leads to blocked sample outlet 25 or influences testing result.Meanwhile the top of filter mantle 23
Closing can also be flown into the second port 2132 of gas passage 213 to avoid liquid, further, prevent damage air pump.
The working method of sampler 10 briefly described below.
Firstly, object to be detected is put into sample receiving portion 20, specifically, outer cover 212 is opened, object to be detected is put into
In filter mantle 23, outer cover 212 is then closed, opens sampler 10, grinder 24 crushes object to be detected to form solidliquid mixture,
Later, air pump operates, so that positive pressure is formed in shell 21, so that the liquid in filter mantle 23 is quickly precipitated from filter mantle 23,
Later, test strips loading part 40 is inserted into, sample liquid flows out to infiltrate test strips from sample export 25, obtains testing result.?
At this moment sample liquid outflow needs to stop the output of sample liquid by after a certain period of time, the amount of the liquid in micropore cup 42 is enough, and need
Sample liquid is flowed back, therefore, air pump operating, so that negative pressure is formed in shell 21, so that sample liquid flows back.In sample liquid reflux course
In, due to forming negative pressure, sample liquid may be in the second port 2132 in inflow gas channel 213, to block second port, even
It flows back into air pump, damages air pump.But due to being additionally provided with gas-guide tube 50, the ventilation of gas-guide tube 50 in gas passage 213
The opening direction of the second port 2132 of the opening direction and gas passage 213 in hole 52 is vertical, even if liquid enters gas
The second port 2132 in body channel 213, can not flow into gas-guide tube 50, and gas still can pass through the venthole of gas-guide tube 50
52 free in and out.
