Description

Manual extractor of cream class cosmetics

Technical Field

The invention relates to the field of cosmetic inspection, in particular to a manual taking and discharging device for sampling and discharging samples in the process of inspecting cream cosmetics.

Background

Cream cosmetics are viscous and poor in fluidity, and in the inspection process, when a sample is taken from a sample packaging bottle to a weighing bottle, if a medicine spoon is used as a sampling tool, the sample is easy to take, but the cream cosmetics are difficult to flow into the weighing bottle quickly under the action of gravity because the cream cosmetics are viscous in texture and small in fluidity and are stuck on the medicine spoon for a long time, so that the cream cosmetics are long in time consumption in the operation process; if a suction pipe is used as a sampling tool, the suction process needs to be carried out slowly, when the operation is too fast, part of cream cosmetics in the bottle enters the suction pipe, and cannot flow to the suction pipe quickly due to poor fluidity of cream at the periphery of the cream cosmetics, air above a sampling point can enter a filling vacant position at the moment and then is sucked into the suction pipe, samples at the inlet of the suction pipe are adhered to the inner wall of the suction pipe due to the suction of air in the suction pipe, an air channel is flushed in the middle, at the moment, the air pressure generated by pinching the top of the suction pipe by hand can only discharge the air in the suction pipe and a very small amount of wall-adhered samples, most of samples are still adhered to the inner wall of the suction pipe due to poor fluidity, the process of 'slow suction-slow discharge' needs to be repeated for several times to meet the sample amount required by one-time inspection in the weighing bottle, and the consumed time is long; the air at the top of the suction pipe is easy to splash instantly along with the process that a part of samples are discharged out of the suction pipe; whether the sample is agglomerated to flow into the weighing bottle under the action of gravity or splashed into the weighing bottle along with air in the suction pipe, the amount of the sample entering the weighing bottle is difficult to control, and once more samples are discharged instantly and exceed a standard allowable sample weighing range, one weighing bottle needs to be taken again for resampling and weighing; the sample is easy to oxidize in the long-time sampling and sample discharging process, and particularly when the items which are easy to oxidize such as hair dye components and hydrogen peroxide components are detected, the detection data is small, and the accuracy of the result is influenced.

Disclosure of Invention

Aiming at the defects that the prior art is long in time consumption, the accuracy of a measuring result is influenced by the fact that a sample is easily oxidized, sample discharging splashing is caused by the existence of air at the top of a suction pipe, sample waste is caused by serious wall adhesion, and the like, the invention provides a manual taking and discharging device for cream cosmetics.

The invention is realized by the following technical scheme: a manual extractor for cream cosmetics comprises a piston unit 1, a sampling unit 2 and a sample discharging unit 3. The piston unit is provided with a hollow piston rod 1-1, the top of the piston rod is provided with a piston head 1-2, a filter membrane 1-3 is arranged inside the piston head, sieve plates 1-4 and 1-5 are arranged on the upper side and the lower side of the filter membrane, a seal ring 1-6 is arranged between the piston head and the sampling unit, the bottom of the piston rod is provided with a piston handle 1-7, and the middle of the piston handle is provided with an air outlet 1-8. The sampling unit 2 is located the outside of piston unit 1, the sampling unit 2 is equipped with sampler barrel 2-1, the inside sample chamber that is hollow structure of sampler barrel, sampler barrel top periphery is equipped with annular screens 2-2, sampler barrel bottom periphery is equipped with screw thread 2-3, the sampler barrel lateral wall is equipped with the scale mark. The sample arranging unit 3 is located below the sampling unit 2, the top of the sample arranging unit 3 is provided with a thread 3-1 which can be screwed with the thread 2-3 and used for fixing the sampling unit 2 and the sample arranging unit 3, the bottom of the sample arranging unit 3 is provided with a sample arranging needle 3-2, and a needle cover 3-3 is arranged below the sample arranging needle 3-2.

Further, the air outlets 1 to 8 are positioned on the side surface of the piston rod

Further, the filter membrane is made of nylon with a pore size of 45 microns, so that air can pass through the filter membrane quickly, but cream cosmetics cannot pass through the filter membrane.

Furthermore, the height of the sampling cylinder can be 2-10cm, the inner diameter of the sampling cylinder can be 0.5-2cm, and the sampling cylinder with the proper height and the proper inner diameter is selected according to the shape of a sample packaging bottle to be sampled and the weight of a sample to be weighed in the inspection.

Further, the length of the sample pin can be 2-20cm to ensure that the bottom of the sample pin is accessible above the bottom of the weighing bottle.

The invention has the technical effects and advantages that:

1. the manual extractor for cream cosmetics can quickly finish sampling and sample discharging operations of cream cosmetics in an inspection process, saves operation time, effectively reduces the oxidation process of samples in the sampling and sample discharging processes, and reduces the influence on result accuracy due to the long sampling and sample discharging time.

2. Through discharging the air above the sample in the sampling cylinder, the problem of splashing of the sample in the sample discharging process is effectively solved.

3. The sample enters the weighing bottle through the sample discharge needle in the process of pushing down the piston, and the existence of the piston effectively solves the problem that cream cosmetics are seriously adhered to the wall of a sampling and sample discharging tool.

4. The sample discharging speed is controlled by controlling the push-down speed of the piston, and the sample can be pushed down slowly when the sample weighing required by the test is approached, so that the problem of sample weighing excess caused by splashing and gravity natural flow is effectively avoided.

5. The method is simple and convenient to operate, short in time consumption, free of splashing and wall adhesion in the sample taking and discharging process and controllable in sample discharging speed when being applied to the inspection process of cream cosmetic finished products.
