Description

[0001] Device for testing pollutant absorption [0002]

The present invention relates to a pollution adsorption test apparatus.

Recently, there have been many suspended substances in the atmosphere. These suspended substances are mainly composed of primary dusts discharged directly or indirectly by artificial pollutants (factory chimneys, automobiles, etc.) and secondary products Dust.

Particularly, suspended particles have fine dusts of 10 μm or less. These fine dusts are the pollutants emitted from coal fuels in Korea, or the dusts flying to China from the northwest winds in China are pollutants in Korea, and the concentration of these fine dusts is increasing.

Many products have been released to prevent fine dust from being adsorbed on the skin when the concentration of fine dust increases.

However, there was no device that could actually test products before they were introduced to prevent adsorption of fine dust. Accordingly, there is a need for an apparatus that can easily determine the degree of fine dust adsorption of a product before product launch.

One embodiment of the present invention relates to a pollution adsorption test apparatus capable of testing the extent to which contaminants are adsorbed on a sample of a product for skin protection.

According to an aspect of the present invention, there is provided a portable terminal comprising: a case having a charging port formed therein for charging a body part; A sample container provided inside the case and containing contaminants; And an air supply unit connected to the sample container and configured to introduce air into the sample container.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

FIG. 1 is a perspective view schematically showing a pollutant adsorption test apparatus according to an embodiment of the present invention. FIG. 2 is a perspective view showing a state in which a door is opened in a pollutant adsorption test apparatus according to an embodiment of the present invention. FIG. 3 is an enlarged view of a sample container installed in a pollutant absorption test apparatus according to an embodiment of the present invention. FIG. 4 is a cross- Fig.

Here, the pollutant includes a chemical substance, a harmful substance, and the like.

Referring to FIG. 1, a pollutant adsorption test apparatus 100 according to an embodiment of the present invention is a test apparatus for determining whether or not fine dust is adsorbed on a product that protects skin exposed to external fine dust. At this time, the product for protecting the skin may be a product applied to the surface of the skin, and more specifically, the product for protecting the skin may be a cosmetic product, an ointment, a external preparation, and the like.

To this end, the pollutant absorption test apparatus 100 includes a case 110, a sample container 120, and an air supply unit 130.

The case 110 may have a hollow shape having an inner space and may be made of a transparent material so that the inside of the case 110 can be recognized from the outside.

In the present invention, the shape of the case is described as an enclosure. However, the present invention is not limited thereto. If a space for testing a sample can be formed by providing a sample container therein, it is possible to form a hexahedron, a cylinder, And the like can be formed in various forms.

In addition, an inlet 112 may be formed at one side of the case 110 so that a part of the body can be inserted into the internal space. At this time, a shielding member 113 extending outward from the case 110 side may be coupled to the input port (112 of FIG. 2).

The shielding member 113 may enclose other parts of the body that are not inserted into the case 110 to block the connection between the case 110 and the outside.

More specifically, when a part of the body put into the case 110 is the user's arm, for example, the user's hand and a part of the arm are inserted into the case 110. The arm portion that is not inserted into the case 110 is covered by the shielding member 113.

At this time, an attachment member 114 for fixing the user's body part may be coupled to the distal end of the shielding member 113. More specifically, after the user puts his / her arm and hand into the case 110, the shielding member 113 can be fixed to the user's arm using the attachment member 114 of the shielding member 113.

Accordingly, the shielding member 113 is fixed to a part of the body by the attachment member 114, so that the pollutants inside the case 110 can be prevented from moving to the outside during the experiment.

Here, the shielding member 113 may be a waterproof cloth material, and the attachment member 114 may be a material such as a ball, a button, or the like.

Also, the arms inserted into the case 110 through the inlet 112 must be parallel to allow contaminants to fall onto the skin, and it may be difficult to maintain parallelism during the test. In order to maintain the parallelism of the arm, a seating part 115 on which the arm is placed may be coupled to the bottom of the case 110.

Meanwhile, a door 116 for opening and closing the inside of the case 110 may be coupled to the case 110.

One end of the door 116 is hinged to the case 110 to open or close the inner space of the case 110 and the door 116 can be pivotally moved relative to the case 110.

Accordingly, after the contaminants are injected into the case 110, the door 116 can be opened to clean the internal space of the case 110, or a second valve (not shown) 152, respectively.

2, a sealing member 117 for sealing the inner space of the case 110 may be provided on one side of the door 116 facing the case 110. As shown in FIG.

Accordingly, the pollutant absorption test apparatus 100 can block the inside of the case 110 from the outside by the sealing member 117.

A pressure measuring unit 118 for measuring the pressure inside the case 110 may be coupled to the upper side of the case 110. The pressure measuring unit 118 may measure the pressure inside the case 110 when the contaminants are discharged into the case 110.

Accordingly, the operator can determine whether the pollutant is grown or released by the pressure inside the case 110 measured by the pressure measuring unit 118 or by determining the end time of the test of the sample.

3, the sample container 120 receives contaminants for discharging contaminants to the case 110 and is coupled to the inner space of the case 110. [ More specifically, the sample container 120 is coupled to one side of the upper side of the case 110, and a part of the sample container 120 is coupled to the upper side of the case 110 in a protruding manner.

Specifically, the sample container 120 includes a container case 121 having an opening 123 opened in one direction, and a lid 122 closing the opening 123 of the container case 121.

At this time, since the contaminants must flow into the container case 121 through the opening 123, the opening 123 must communicate with the outside of the case 110. The container case 121 is positioned above the inside of the case 110 so that the opening 123 protrudes outside the case 110.

The sample container 120 is connected to the air supply unit 130 to discharge the contaminants introduced into the case 110.

4, a first flow path 141 through which the air supplied from the air supply unit 130 flows is coupled to one side of the sample container 120, and a first flow path 141 through which the contaminants in the sample container 120 and the air The second flow path 142 may be coupled to the second flow path 142. [

At this time, the first flow path 141 is coupled to the upper side of the sample container 120, more specifically, the upper side of the first side of the case 110, and is coupled to the upper side of the first flow path 141. The second flow path 142 is connected to the lower surface of the sample container 120 facing the one surface of the sample container 120 to which the first flow path 141 is coupled, To the inner space side of the case 110. [0054]

The first flow path 141 may be provided with a first valve 151 that opens or closes the first flow path 141 so that air supplied from the air supply unit 130 flows into the container case 121 And the second flow path 142 may be provided with a second valve 152 for opening or closing the second flow path 142 to discharge the contaminants in the sample container 120 to the case 110.

At this time, the degree of discharge of contaminants discharged into the case 110 through the first valve 151 and the second valve 152 can be finely adjusted.

Meanwhile, the inclined surface 124 may be formed in the sample container 120 so that contaminants are collected on the second flow path 142 side. At this time, the inclined surface 124 is inclined from the side surface of the container case 121 to the bottom surface, and is formed on the side surfaces of the container case 121 except for the side surface of the container case 121 to which the second flow path 142 is coupled .

The contaminants introduced through the opening 123 of the sample container 120 are collected on the bottom surface of the container case 121 along the inclined surface 124 formed on the side surfaces of the container case 121, The air is discharged into the case 110 through the second flow path 142 by the air.

The air supply unit 130 is connected to the first flow path 141 and can supply air into the sample container 120.

Hereinafter, a process of performing the fine dust adsorption test using the pollutant adsorption test apparatus 100 having the above-described structure will be described.

5A to 5C are diagrams illustrating a procedure of using a pollutant adsorption test apparatus according to an embodiment of the present invention.

First, in the embodiment of the present invention, the body put into the case 110 is the arm, the exposed part of the operator's arm is referred to as the test part, and the products used for the test are referred to as the sample.

According to Fig. 5A, according to an embodiment of the present invention, the operator shields the area except the test area A with the protective equipment 10 so as not to be exposed to contaminants. The test area (A) is cleaned with a cleaning agent and dried naturally in a constant temperature and humidity space.

At this time, a part of the protective equipment 10 is opened, and the test part A is exposed to the outside with the opened part.

The baseline is measured by an image photograph or a magnifying lens on the test area A exposed to the opening of the protective equipment 10. Then, as shown in Fig. 5A, the test site A exposed to the opening is coated with the products used for the test and absorbed sufficiently.

 At this time, the products are prepared for testing and products to be compared with the products for testing and applied to the test site (A). Here, in one embodiment of the present invention, the product for the test is referred to as a test sample, and the product for the control is referred to as a control sample.

On the other hand, in the present invention, four control specimens and four test specimens are shown to be applied in a rectangular shape, but the present invention is not limited thereto. That is, the area, shape, arrangement or number of the control sample and the test sample applied to the test site (A) can be variously changed depending on the test characteristics of the sample.

Then, the lid 122 of the sample container 120 is opened and the contaminant P is introduced into the sample container 120. At this time, the contaminant is a substance that replaces the fine dust, and the fine dust has a diameter of 10 mu m. Therefore, the contaminant (P) used in the present invention may be a material having a diameter of 10 μm or less. More specifically, carbon or iron oxide among the substances having a diameter of 10 탆 or less can be used as a contaminant.

In an embodiment of the present invention, 0.5 g of contaminants P are introduced into the interior of the sample container 120, and the air supply unit 130 is operated to set the pressure inside the case 110.

More specifically, the first valve 151 is opened to supply air into the sample container 120, and the contaminant P is discharged through the second flow path 142, Can be measured by the pressure measuring unit 118. [

At this time, the operator can determine whether the pollutant P is discharged through the pressure measured by the pressure measuring unit 118 or the end point of the test of the sample.

Then, as shown in FIG. 5B, the arm wearing protective equipment is inserted into the case 110 through the input port 112, and is seated in the seating part 115. At this time, the contaminants are made to be in line with the second flow path 142 in which the contaminants are injected.

Further, the shielding member 113 is fixed to the arm using the attachment member 114 of the shielding member 113 to prevent the contaminants in the case 110 from flowing to the outside.

Thereafter, the first valve 151 is opened to supply air to the sample container 120 side to discharge the pollutant P through the second flow path 142. At this time, the first valve 151 is opened three to four times at intervals of 5 minutes.

Here, in the present invention, the first valve is opened so that the pollutants are discharged about 3 to 4 times at intervals of 5 minutes, but the present invention is not limited thereto. That is, it is noted that the test can be performed according to the test characteristics of the sample or the amount of the pollutants P injected into the case 110.

After the pollutant injection is finished, as shown in FIG. 5C, the pollutant P injected into the case 110 is sufficiently left to stand free to fall, the arm attachment member 114 is removed, The arm is taken out of the case (110).

Then, an image or a magnifying glass is taken in the same manner as the baseline. At this time, measurement is made in a non-contact manner so that the test site is not crushed.

The color of the contaminant (P) attached to the test site relative to the baseline is analyzed as a pixel value to confirm the degree of adsorption of contaminants on the test product.

Thereafter, the operator opens the door 116 to perform cleaning such as removing contaminants P injected into the case 110. [

Accordingly, by injecting a part of the body coated with the sample in the case and injecting the contaminant into the case to drop the contaminant on the sample, the degree of adsorption of the contaminant to the sample can be determined.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
