Description

Technical Field

[0001] The utility model relates to the field of chemical sample detection and sampling, and more specifically, to a portable electric sampler. Background Art

[0002] The existing sampler is a round tube with an inclined cut at the front end and a smooth tail. When in use, hold the tail by hand and insert the front end of the cylinder into the bag. The inclined cut of the cylinder easily allows the cylinder to insert into the inside of the bag, and the medicament will enter the inside of the cylinder. Then, the cylinder is taken out, and a part of the sample will be brought out from the inside of the cylinder. Then, the sampler is stood upright and shaken to make the sample come out of the inside of the cylinder to complete the sampling. However, due to the differences in the samples, some samples are in a loose sand shape and have strong fluidity. When the cylinder is pulled out, the sample inside the cylinder will be lost as the cylinder is pulled out, resulting in sampling failure; some samples are too fine or contain a certain humidity, resulting in extremely low efficiency of the sampler in bringing out the sample, and thus the sampling operation cannot be completed. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a portable electric sampler, which can reduce the sampling time, avoid sample spillage, and make the sampling operation more convenient.

[0004] The technical solution adopted by the utility model to solve its technical problems is: to construct a portable electric sampler, which includes a sampling tube, a sampling chamber, and a power device. The tail of the sampling tube is connected to the sampling chamber, and the sampling chamber is connected to the power device;

[0005] The upper part of the sampling chamber has a chamber top cover. A filter partition is fixed at the tail section of the inner wall of the sampling chamber. A nylon fiber mesh board is fixedly installed on the inner wall of the filter partition. The lower part of the sampling chamber is provided with a discharge port, and the discharge port is connected to a discharge pipe;

[0006] The power device includes a housing. A hollow circular plate is fixed at the middle position of the inner wall of the housing. An impeller is rotatably connected to the front part of the hollow circular plate. A motor is fixedly installed at the rear part of the hollow circular plate. The output shaft of the motor is fixedly connected to the bottom of the impeller. The motor drives the impeller to rotate to generate suction.

[0007] In the above solution, the head of the sampling tube is in a cut shape.

[0008] In the above solution, the front end of the chamber top cover is hinged and installed on the sampling chamber through a horizontal axis, and the rear end of the chamber top cover is fixed to the sampling chamber through a buckle.

[0009] In the above solution, locking buckles are provided at both ends of the filter partition, and corresponding locking grooves are provided on the inner side surface of the sampling chamber. The locking buckles and the locking grooves cooperate to achieve snap fixation.

[0012] In the above solution, a perforated plate is detachably connected to the bottom of the motor.

[0013] Implementing the portable electric sampler of the present utility model has the following beneficial effects:

[0014] 1. After the power device of the present utility model is externally connected to the sampling bin, it can provide sufficient suction to extract the samples in the bag. The sampling tube, the sampling bin, and the power device are located on the same axis, and the air flow direction remains basically the same during the air suction and filtering process without change, reducing the loss of air flow intensity and ensuring the maximum dust suction efficiency, which is particularly effective for fine particles with strong fluidity or certain humidity.
