Utility Model Content

[0004] The purpose of this invention is to overcome at least one of the defects in the existing technology and provide a comprehensive cosmetic testing device. This invention improves the integration and convenience of cosmetic safety testing.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] One of the technical solutions of this utility model is to provide a comprehensive cosmetic testing device. The device includes a box with a glove opening connected to a glove. The box contains an activity space and a testing chamber. The activity space is used to house animals. The testing chamber is connected to an external cosmetic production line and discharged from the testing chamber via an inlet pipe and a outlet pipe. Heating wires are installed in the walls of the testing chamber, and an outlet pipe with a valve is installed on the top of the testing chamber. Cosmetics enter the testing chamber and undergo high-temperature testing via the heating wires. Cosmetics are removed before and after testing via the outlet pipe, and the valve controls whether or not to discharge. Testers wear gloves through the glove opening and conduct cosmetic animal experiments on animals inside the box.

[0007] As a preferred technical solution, a glove opening is provided on the wall of the box, and a test chamber is provided on the wall of the box.

[0008] Furthermore, the box is divided into multiple activity spaces by partitions.

[0009] As a preferred technical solution, the box body is divided into multiple activity spaces by partitions on the wall surface.

[0010] Furthermore, the test chamber is equipped with and exhausts test gases through an air inlet pipe and an exhaust pipe, allowing cosmetics to enter the test chamber for atmosphere testing.

[0011] As a preferred technical solution, the test gas includes oxygen or vapor, which are used for oxidation or damp heat testing, respectively.

[0012] As a preferred technical solution, a heating wire or light source is used to raise the temperature of the test gas for high-temperature oxidation or damp heat testing.

[0013] Furthermore, the testing chamber is equipped with a light source and a light-transmitting baffle. The testing chamber is divided into two testing spaces by the light-transmitting baffle. One testing space is equipped with a light source, and the other testing space contains cosmetics. While the light-transmitting baffle isolates the light source from contact with the cosmetics, light is allowed to pass through the light-transmitting baffle to irradiate the cosmetics. The cosmetics enter the testing chamber and undergo light irradiation testing by the light source.

[0014] As a preferred technical solution, the light source is selected with different wavelengths to conduct aging tests in the corresponding bands.

[0015] As a preferred technical solution, the walls and light-transmitting baffles of the test chamber are pressure-resistant to prevent excessive gas pressure from damaging the test chamber.

[0016] As a preferred technical solution, a light source is provided on the wall surface of the test chamber.

[0017] Furthermore, one end of the feed pipe and the air inlet pipe extends into another test space of the test chamber, passes through the light-transmitting baffle, the wall of the test chamber, and the wall of the box, and then extends out of the box. One end of the discharge pipe and the exhaust pipe is connected to another test space of the test chamber, passes through the wall of the test chamber and the wall of the box, and then extends out of the box. Valves are installed on the feed pipe, discharge pipe, air inlet pipe, and exhaust pipe. All cosmetics and test gases are located in another test space of the test chamber to avoid affecting the light source. The valves control whether to feed, discharge, or exhaust.

[0018] Furthermore, one end of the feed pipe in the other test space of the test chamber is lower than the air inlet pipe, and one end of the discharge pipe connected to the other test space of the test chamber is lower than the exhaust pipe. The test gas is located in the upper part of the other test space of the test chamber, and the cosmetic is located in the lower part of the other test space of the test chamber, so as to avoid the test gas directly entering the cosmetic and generating bubbles, which would affect the quality.

[0019] Furthermore, a transfer chamber is provided below the testing chamber inside the box. This transfer chamber is integrated with the wall of the box. One side of the transfer chamber inside the box and the other side of the box wall are both set as doors. The doors are equipped with handles. The transfer chamber is used to transfer tools such as petri dishes and animals between the outside world and the box. The doors are opened for transfer, and the handles facilitate opening the doors. The top platform of the transfer chamber holds the petri dishes and other tools. The testers drip the cosmetics taken from the discharge tube into the petri dishes for animal experiments. Animals can be exposed to the volatile atmosphere of the cosmetics or absorb the cosmetics for toxicological testing.

[0020] Furthermore, the box is equipped with a tool rack that holds tools such as tweezers.

[0021] As a preferred technical solution, a tool rack is provided on the wall of the box.

[0022] Furthermore, the top wall of the box is set as a box cover, and the box cover is provided with a handle. The box cover can be opened to install internal components, or tools and animals can be placed directly inside. The handle makes it easy to open the box cover.

[0023] Furthermore, the enclosure is equipped with a ventilation pipe with a valve, through which air is supplied to the animal for survival, and the valve controls whether or not ventilation is provided.

[0024] As a preferred technical solution, a vent pipe is provided on the wall of the box.

[0025] As a preferred technical solution, the enclosure is made of transparent material to facilitate observation of the animals by testers.

[0026] One of the technical solutions of this utility model is to provide a comprehensive testing method for cosmetics. This method uses the aforementioned device to conduct comprehensive testing of cosmetics, and includes the following steps:

[0027] Testers put on gloves through the glove opening, took out a petri dish from the transfer chamber and placed it on the top platform of the transfer chamber. They dripped cosmetic into the petri dish through the discharge tube. After taking an appropriate amount of cosmetic, they took tweezers from the tool rack, used the tweezers to pull open one eyelid of the rabbit and dripped the cosmetic into it. The other eye served as a control group. At this time, air was introduced into the ventilation tube to maintain environmental stability and ensure the animal's breathing.

[0028] If cosmetics can evaporate into the air, the cosmetics in the petri dish can be mixed with the air breathed by the animal to test their volatility safety.

[0029] Turn on the heating wire to conduct a high-temperature test on the cosmetics in the testing chamber;

[0030] The tested cosmetics are discharged through the discharge pipe, and new cosmetics are connected through the inlet pipe. The air inlet and exhaust pipes are opened to conduct an atmosphere test on the cosmetics in the test chamber.

[0031] The tested cosmetics are discharged through the discharge pipe, and new cosmetics are introduced through the feed pipe. The light source is turned on to conduct light tests on the cosmetics in the testing chamber.

[0032] When no further testing is needed or when there is too much cosmetic in the testing room, the cosmetic can be discharged through the discharge pipe.

[0033] As a preferred technical solution, the device can be connected to the cosmetic production line as an intermediate online animal experiment testing device. In this case, the feed pipe and discharge pipe are kept fully open, and the cosmetic is only dripped into the petri dish through the discharge pipe when needed to prepare for animal experiments, rather than the device being connected to the cosmetic production line as an offline testing device that can be switched on and off as needed.
