Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of samplers, in particular to a laundry detergent sampler. Background Art
[0002] In daily life, laundry detergent is a common washing product; its working principle is similar to that of traditional washing powder and soap, and its active ingredients are all surfactants. After the laundry detergent is produced inside the raw material barrel, it needs to be sampled and tested to analyze whether the product is qualified, so a laundry detergent sampler is needed.
[0003] Existing laundry detergent samplers generally utilize a piston disposed inside a sampling tube to extract laundry detergent; however, when the existing laundry detergent samplers extract laundry detergent at different depths in a raw material barrel, since the sampling tube can easily bring the laundry detergent at the top of the sampling tube into the sampling tube during the insertion process, the sample extracted by the sampling tube will be mixed with a small portion of the laundry detergent at the top of the sampling tube, thereby affecting the detection result of the sample.
[0004] A sampler is proposed in a Chinese patent with publication number CN219798840U, which drives a conveyor belt to rotate by a servo motor, and the conveyor belt drives a fixed sampling head connected to the outer ring of the conveyor belt to move, so that the sampling head extracts laundry detergent of different depths through a liquid extraction pump, thereby sampling laundry detergent of different depths.
[0005] Although the above technical solution can sample laundry detergent of different depths, it can only extract laundry detergent of a certain depth each time, and cannot extract laundry detergent of multiple depths at one time. When extracting laundry detergent of multiple depths, the extraction process needs to be repeated multiple times, which is cumbersome.
[0006] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In order to achieve the above-mentioned purpose, the utility model provides a laundry detergent sampler, comprising a sampling cylinder, wherein the side wall of the sampling cylinder is provided with a plurality of sampling nozzles equidistantly in the vertical direction; a piston 1 corresponding to the position and number of the sampling nozzles is provided inside the sampling cylinder, and a piston 2 fitting the top of each piston 1 is provided;
[0009] A connecting rod 1 is provided on the outer top of the sampling cylinder, and the connecting rod 1 sequentially penetrates the top of the sampling cylinder and a plurality of pistons 2 and is connected to all the pistons 1;
[0010] The outer top of the sampling tube is also provided with a ring sleeved on the periphery of the connecting rod 1, and the bottom of the ring is provided with a plurality of connecting rods 2, and all the connecting rods 2 sequentially penetrate the top of the sampling tube and a plurality of pistons 1 and are connected to all pistons 2.
[0011] According to the laundry detergent sampler described in the utility model, the inlet end of the sampling nozzle is funnel-shaped.
[0012] According to the laundry detergent sampler described in the utility model, one end of the connecting rod located outside the sampling tube is connected to a lifting ring.
[0013] According to the laundry detergent sampler described in the utility model, an auxiliary ring is provided on the peripheral fixed ring of the connecting rod 1, and the auxiliary ring is located between the circular ring and the outer top of the sampling tube.
[0014] According to the laundry detergent sampler described in the utility model, the top of the sampling tube is separately arranged from the sampling tube.
[0015] According to the laundry detergent sampler described in the utility model, the sampling cylinder is composed of a plurality of sub-cylinder bodies connected and combined.
[0016] The utility model provides a laundry detergent sampler, which has the following beneficial effects:
[0017] 1. By pulling the connecting rod 1 and the ring upward at the same time, the connecting rod 1 and the ring move upward and drive all the pistons 1 and 2 to move; so that multiple negative pressure areas are formed inside the sampling cylinder, so that laundry detergents of different depths are sucked into the sampling cylinder through multiple sampling nozzles at the same time, thereby achieving the purpose of extracting laundry detergents of multiple depths at the same time, simplifying the extraction process and shortening the extraction time.
[0018] 2. By setting the inlet end of the sampling nozzle to be funnel-shaped, the resistance encountered by the laundry detergent when entering from the sampling nozzle is smaller, and the resistance encountered by the laundry detergent when flowing back from the sampling nozzle is larger; this not only facilitates the laundry detergent to enter the sampling nozzle during sampling, but also prevents the laundry detergent in the sampling nozzle from dripping, thus avoiding the situation where the laundry detergent drips and needs to be cleaned.
[0019] 3. By separating the top of the sampling tube from the sampling tube, when the top of the sampling tube is removed, the piston 1 and the piston 2 inside the sampling tube can be taken out at the same time, so that the staff can replace the piston 1 and the piston 2 conveniently.
[0020] 4. By splitting the sampling cylinder, a plurality of separate sub-cylinder bodies can be obtained, which is convenient for cleaning the inner wall of the sampling cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
