Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a liquid food detects uses portable sampling device, including an aspiration tube 1, the bottom of aspiration tube 1 is equipped with liquid suction pipe 7, the inside of aspiration tube 1 is equipped with piston 6, can extract outside liquid, the top of piston 6 is equipped with pull rod 3, the inside both sides of piston 6 are equipped with logical groove 9 respectively, one side that leads to the groove 9 inner wall is equipped with mounting bracket 10, one side of mounting bracket 10 is equipped with outer tube 11, the inside of outer tube 11 is equipped with spring 8, one side of spring 8 is equipped with interior sleeve pipe 12, one side of interior sleeve pipe 12 is equipped with card pearl 13, the top of aspiration tube 1 one side is equipped with reservoir B5, one side at reservoir B5 top is equipped with gas vent 4, the top of aspiration tube 1 opposite side is equipped with reservoir A2.

Further, the bottom in the 1 outside of a drawing liquid section of thick bamboo is equipped with holds the ring, and holds the outside of ring and be equipped with anti-skidding line, skids when placing the gripping, leads to the device to drop to ground and causes the harm.

Furthermore, a liquid discharge port is formed in the bottom of one side of the liquid storage tank B5, and a plug plate is arranged inside the liquid discharge port, so that liquid inside the liquid discharge port can be conveniently discharged.

Further, a liquid filling port is formed in the top of one side of the liquid storage tank A2, and a cover plate is arranged inside the liquid filling port, so that liquid can be replenished into the liquid storage tank.

Furthermore, the top of the pull rod 3 extends to the outside of the liquid extraction cylinder 1 and is provided with a pull plate, and the pull plate is made of a semicircular structure, so that the pull rod 3 can be conveniently pulled.

Further, the top of the pull rod 3 is provided with a hard rubber ring, and the pull rod 3 is positioned in the hard rubber ring, so that the sealing effect is improved.

The working principle is as follows: when a sample is collected, firstly, the piston 6 is pushed to the bottom through the pull rod 3, the liquid pumping pipe 7 is placed at a liquid sample to be collected, then the pull rod 3 is pulled upwards, so that the air pressure of a cavity at the bottom of the piston 6 is lowered, the sample is pumped into the cavity at the bottom of the piston 6, meanwhile, the air pressure of the cavity at the top of the piston 6 is raised, when the sample is extracted, the blocking bead 13 at the position close to the liquid storage tank B5 is influenced by the air pressure to remove the blocking of the liquid storage tank B5, the inner sleeve 12 is driven to move towards the inside of the outer sleeve 11, and the spring 8 is driven to contract at the same time, so that the air in the cavity at the top of the piston 6 flows into the liquid storage tank B5 through the through groove 9 and is discharged from the exhaust port 4;

when a sample needs to be stored, the liquid pumping pipe 7 is placed at the storage bottle, then the pull rod 3 is pushed downwards, the pull rod 3 drives the piston 6, so that liquid in a cavity at the bottom of the piston 6 is discharged into the storage bottle through the liquid pumping pipe 7, meanwhile, the air pressure in a cavity at the top of the piston 6 becomes low in the process that the piston 6 moves downwards, the blocking bead 13 close to the liquid storage tank A2 is enabled to unblock the liquid storage tank A2 under the action of negative pressure, then cleaning liquid in the liquid storage tank A2 is pumped to the top of the piston 6, further, the interior of the piston 6 is cleaned, meanwhile, the blocking bead 13 close to the liquid storage tank B5 continues to block the liquid storage tank B5 under the action of negative pressure, the situation that the air in the liquid storage tank B5 enters the interior of the liquid pumping cylinder 1 to cause the situation that the liquid in the liquid storage tank A2 cannot be pumped is caused, when a group of liquid is continuously pumped, the piston 6 moves upwards, so that the blocking bead 13 close to the liquid storage tank B5 is squeezed into the through groove 9 under the action of air pressure, the liquid in the top cavity of the piston 6 is then discharged through the through slot 9 into the reservoir B5 for storage.
