[0003] The document CN220625879U discloses a kind of food detection sampler, it is related to food detection device technical field, including rubber ball and containing pipe, the bottom of the rubber ball is provided with rubber suction interface, the top of the containing pipe is provided with upper interface, the bottom end of the rubber suction interface is provided with extension pipe.The utility model by using small interface insertion into the fluid food to be detected, extruding rubber ball can make its internal air be ejected from below, with the negative pressure generated by the resilience of rubber ball, so that small interface inhales fluid food sample, fluid food sample enters into containing pipe, extruding rubber ball can extrude fluid food sample to sample box in later period, before sampling, small interface can be inserted into inner mouth interface, large interface is inserted into fluid food sample to sample, soft viscous fluid food sample can be extracted, it will not be blocked, it is relatively simple to operate, when sampling powder food, sample spoon can be used to directly dig sample, the whole device structure is simple, and the function is perfect.

[0004] The above technical scheme can extract soft viscous fluid food sample, and the operation is simple and will not be blocked, but in actual use, only part of sample can be extracted at a time, and when more samples need to be extracted, rubber ball needs to be pressed again, and then the sample in containing pipe is extruded outward again, so it does not have practicality, and therefore, it can be further improved. UTILITY MODEL CONTENTS

[0005] To solve the problems proposed above, the utility model provides the following technical scheme: a kind of finished dish quantitative sampler, including suction cylinder, the top of the suction cylinder is fixedly installed with top frame, the center of the top frame is slidably inserted with pull rod, the inside of the suction cylinder is slidably connected with piston block, and the bottom end of the pull rod is fixedly installed in the top side center of piston block, the bottom center of the suction cylinder is fixedly installed with connecting pipe, the bottom end of the connecting pipe is fixedly installed with storage tank, the bottom side center of the storage tank is fixedly installed with flat suction pipe, the bottom of the suction cylinder is equipped with exhaust port on both sides, the suction cylinder is provided with the plugging and dredging component for plugging or dredging corresponding both sides exhaust port.

[0006] As an optimization, the blocking and dredging component includes a fixed frame that is fixedly installed on both sides of the suction cylinder at the exhaust port. A sliding plate is slidably connected inside the fixed frame. A sliding rod is fixedly installed in the middle of the sliding plate. A pressing plate is fixedly installed at one end of the sliding rod that passes through the fixed frame. A tension spring is fixedly installed between the sliding plate and the inner wall of the fixed frame. A sealing block is glued to the other side of the sliding plate. By pressing the pressing plate, the sliding plate will slide along the inner wall of the fixed frame, which will push the sealing block into the exhaust port, thereby sealing the exhaust port. At this time, the pull rod can be pulled upward to extract and sample the liquid food.

[0007] As an optimization, the side of the slide plate opposite to the outer side of the suction cylinder has an arc edge and is set to fit the arc surface of the outer side of the suction cylinder.

[0008] As an optimization, the size of the sealing block is set to correspond to the inner diameter of the exhaust port, and the sealing block is made of elastic rubber material.

[0009] As an optimization, limit plates are fixedly installed on both sides of the inner wall of the fixed frame, and the sliding plate is slidably connected between adjacent limit plates.

[0010] As an optimization, a fixing ring is fixedly installed inside the connecting pipe, a return spring is fixedly installed on the top side of the fixing ring, a block is fixedly installed on the top of the return spring, and a through groove is opened on the outside of the connecting pipe corresponding to the block.

[0011] As an optimization, the top of the connecting pipe is provided with a through hole whose inner diameter is smaller than the outer diameter of the plug, and four sets of through grooves are arrayed around the outer side of the connecting pipe.

[0012] The beneficial effects of this utility model are as follows: This quantitative sampler for finished dishes allows the sliding plate to be pressed tightly against the outside of the suction cylinder by pinching and pressing the pressing plates on both sides. This causes the sealing block to be embedded into the exhaust port for sealing. Pulling the pull rod then causes the piston block to slide upward, allowing suction to be performed so that the block slides upward and exposes the through groove. Therefore, the food can be sucked into the storage tank along the connecting pipe, facilitating sampling. Furthermore, the spring force of the quantitative sampler causes the sealing block to move out of the exhaust port, thus removing the seal and releasing pressure. This causes the block to reset under the action of the return spring, blocking the through groove. Pressing the pull rod then causes the piston block to slide downward. Because the exhaust port is cleared, no pressure is applied to the block, preventing exhaust along the connecting pipe and thus preventing the sample collected in the storage tank from being squeezed out. This allows for cyclical operation and multiple sample collections as needed. Attached Figure Description

Four groups of through grooves 20 are arranged around the outer side of the connecting pipe 5. The plug 19 is initially blocked in the through groove 20 by the elastic force of the reset spring 18, so that the through groove 20 is blocked to prevent gas from entering the storage tank 6 along the connecting pipe 5 to push out the collected sample. When the sample is sucked, the plug 19 is upwardly slid under the negative pressure suction force, so that the through groove 20 is no longer blocked, and normal suction sampling can be performed.
