Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling equipment technology, specifically a laundry detergent sampling device. Background Technology
[0002] The active ingredient in laundry detergent is mainly nonionic surfactant, whose structure includes a hydrophilic end and an oleophilic end. The oleophilic end binds to the stain, and then the stain is separated from the fabric through physical movements (such as hand rubbing or machine movement). At the same time, the surfactant reduces the surface tension of water, allowing water to reach the fabric surface and enabling the active ingredient to work.
[0003] Since laundry detergent is a liquid, it is mostly sold in pouches or bottles. However, when sampling and testing laundry detergent, it is necessary to take samples from inside the pouches or bottles. Existing laundry detergent sampling equipment cannot be used to sample different types of laundry detergent at the same time, making it inconvenient to use. Utility Model Content
[0004] The purpose of this invention is to provide a laundry detergent sampling device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a laundry detergent sampling device, comprising an outer shell and an air bladder, wherein the air bladder is disposed inside the outer shell and the bottom of the outer shell is sealed by a bottom cover plate, and pressure plates are symmetrically arranged on both sides of the air bladder and the pressure plates are slidably connected inside the outer shell.
[0006] Both the outer shell and the top of the airbag have through slots. A fixed sleeve and a sampling needle are fixedly connected to the top of the outer shell at the position corresponding to the through slot. The sampling needle is located inside the fixed sleeve and extends through the outer shell into the airbag. An adjusting sleeve is movably inserted into the inside of the fixed sleeve. A cap is fixedly connected to the inner wall of the adjusting sleeve and is movably connected to the sampling needle. The cap is adapted to fit the through slot.
[0007] The outer wall of the adjusting sleeve is fixedly connected to a limiting slider, and the inner wall of the fixed sleeve is provided with a limiting groove and a rotating groove. The rotating groove and the limiting groove are interconnected and are both adapted to the limiting slider.
[0008] Preferably, a sliding rod is fixedly connected to the wall of the pressure plate on the side away from the airbag, and the other end of the sliding rod slides through the outer shell and is fixedly connected to a holding plate.
[0009] Preferably, a first spring is sleeved on the rod wall between the holding plate and the outer casing of the slide rod.
[0010] Preferably, the bottom of the adjusting sleeve is provided with an annular groove, and a second spring is provided inside the annular groove, with the other end of the second spring abutting against the top of the outer shell.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the laundry detergent sampling device of this utility model has a simple structure and is practical and convenient. The fixed sleeve set on the outer shell can be connected to the air bag through the through groove. The adjustable sleeve can be freely extended and retracted inside the fixed sleeve. The adjustable sleeve can be aligned with the bottle mouth of the bottled laundry detergent so that the device can sample the bottled laundry detergent. The sampling needle can pass through the packaging bag of bagged laundry detergent to sample the bagged laundry detergent. It can be used to sample laundry detergent with different packaging.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5The present invention provides a technical solution: a laundry detergent sampling device, including an outer shell 1 and an airbag 2. The airbag 2 is disposed inside the outer shell 1, and the bottom of the outer shell 1 is sealed by a bottom cover plate 7. Pressure plates 3 are symmetrically arranged on both sides of the airbag 2, and the pressure plates 3 are slidably connected inside the outer shell 1.
[0020] Both the outer shell 1 and the airbag 2 have through slots 8 at their tops. A fixed sleeve 10 and a sampling needle tube 9 are fixedly connected to the top of the outer shell 1 at the position corresponding to the through slot 8. The sampling needle tube 9 is located inside the fixed sleeve 10 and extends through the outer shell 1 to the inside of the airbag 2. An adjusting sleeve 11 is movably inserted into the inside of the fixed sleeve 10. A cap 14 is fixedly connected to the inner wall of the adjusting sleeve 11 and is movably connected to the sampling needle tube 9. The cap 14 is adapted to the through slot 8.
[0021] A limiting slider 15 is fixedly connected to the outer cylinder wall of the adjusting sleeve 11. A limiting groove 16 and a rotating groove 17 are opened on the inner cylinder wall of the fixed sleeve 10. The rotating groove 17 and the limiting groove 16 are interconnected and are both adapted to the limiting slider 15.
[0022] Preferably, a sliding rod 4 is fixedly connected to the wall of the pressure plate 3 on the side away from the airbag 2. The other end of the sliding rod 4 slides through the outer shell 1 and is fixedly connected to a holding plate 5. The holding plate 5 and the sliding rod 4 can push the pressure plate 3 to apply pressure to the airbag 2 inside the outer shell 1, so that the airbag 2 is compressed. A first spring 6 is sleeved on the rod wall of the sliding rod 4 between the holding plate 5 and the outer shell 1. The elastic force of the first spring 6 can push the holding plate 5 to move and reset in the direction away from the outer shell 1.
[0023] Preferably, the bottom of the adjusting sleeve 11 is provided with an annular groove 12, and a second spring 13 is provided inside the annular groove 12. The other end of the second spring 13 abuts against the top of the outer shell 1. The annular groove 12 allows the adjusting sleeve 11 to be retracted inside the fixed sleeve 10 without being obstructed by the compressed second spring 13, and the elastic force of the second spring 13 can push the adjusting sleeve 11 to reset.
[0024] Specifically, in the initial state, the adjusting sleeve 11 can extend upward under the elastic force of the second spring 13 so that the sampling needle tube 9 is located inside the adjusting sleeve 11, which can effectively prevent the sampling needle tube 9 from being exposed. At this time, the adjusting sleeve 11 and the through groove 8 are in a connected state.
[0025] When using sampling equipment to sample bottled laundry detergent, aligning the adjusting sleeve 11 with the bottle mouth allows the laundry detergent to be filled into the airbag 2 along the adjusting sleeve 11 and the fixed sleeve 10 and through the through groove 8.
[0026] When sampling bagged laundry detergent using the sampling device, press the adjusting sleeve 11 downwards until the limiting slider 15 can rotate along the rotating groove 17. Then, press down and rotate the adjusting sleeve 11. After the adjusting sleeve 11 rotates, it can be locked and the through groove 8 can be sealed by the cap 14. At this time, press the holding plate 5 towards the outer shell 1 to release the gas inside the airbag 2. Then, pass the sampling needle 9 through the laundry detergent packaging bag and release the pressure of the holding plate 5. As the holding plate 5 returns to its original position under the elastic force of the first spring 6, the airbag 2 expands and the laundry detergent inside the bag is drawn into the airbag 2 along the sampling needle 9.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
