Description

Technical Field

[0001] This utility model relates to the field of cosmetic testing equipment technology, and in particular to a device for testing the stability of cosmetics. Background Technology

[0002] Cosmetic stability has always been a crucial concern for researchers during the cosmetics development process, impacting the quality, safety, and stability of cosmetic products. Numerous stability testing methods have evolved during research and development. Depending on the different characteristics of the cosmetic samples, stability testing can employ influencing factor testing, accelerated testing, and long-term testing. Influencing factor testing, also known as destructive testing, includes high-temperature testing, high-humidity testing, light exposure testing, and freeze-thaw testing. By setting different test conditions, it examines relevant indicators such as the cosmetic's appearance, color, odor, pH value, cold resistance, heat resistance, centrifugation test, total bacterial count, total mold and yeast count, viscosity, airtightness, and drop test. In influencing factor testing, the UV accelerated weathering tester simulates ultraviolet radiation from natural sunlight, uses a humidification system to simulate condensation, and simulates rain through spraying to conduct accelerated weathering tests on cosmetics. It artificially recreates environmental conditions such as ultraviolet radiation, high temperature, high humidity, condensation, and rain in natural climates to test the stability of cosmetics.

[0003] UV accelerated weathering testers can reproduce changes in the stability and weather resistance of cosmetics that may take months or years to occur outdoors in just a few days or weeks. However, commonly used UV accelerated weathering testers have only one test chamber and can only test one set of cosmetic samples under the same test conditions and for the same time period at a time. For testing institutions, their samples often have different test conditions and need to be tested at different time periods. The accelerated testing efficiency of a single test chamber is low and it is not convenient to test the stability of multiple cosmetics under different test conditions and at different time points at the same time. Utility Model Content

[0004] To address the technical problems of existing technologies, which allow for testing cosmetic samples under the same conditions and for the same time period each time, resulting in low testing efficiency and low equipment utilization, and making it inconvenient to simultaneously conduct stability tests on multiple cosmetic products under multiple testing conditions and on multiple batches of samples over multiple time periods, this utility model provides the following technical solution.

[0005] This utility model discloses a device for testing the stability of cosmetics, comprising a housing and a test chamber and an equipment box with control panels arranged vertically inside the housing. The test chamber has several test chambers separated by several partitions. Each test chamber has an independent pull-out door at its opening and a filter screen at its bottom that communicates with the equipment box. The test chamber is equipped with several humidifying heads, spray heads, ultraviolet lamps, and semiconductor cooling chips. Each test chamber is independently electrically connected to the control panel. The partitions are slidably connected between the top wall of the test chamber and two adjacent filters to facilitate changing the test space size of the test chamber.

[0006] As a further technical solution, the top of the inner cavity of the test chamber is provided with an upper sliding groove, and a lower sliding groove is provided between two adjacent filter screens. The partition is slidably connected between the lower sliding groove and the upper sliding groove.

[0007] As a further technical solution, the test chamber is provided with a detachable baffle on the side near the pull-out door, and the detachable baffle abuts against the partition.

[0008] As a further technical solution, the partition includes two heat insulation layers on both sides and a waterproof layer and a light-shielding layer between the two heat insulation layers.

[0009] As a further technical solution, the semiconductor cooling chip is used to cool and heat the test chamber and is electrically connected to the control panel to facilitate the switching between cooling and heating.

[0010] As a further technical solution, each of the filter screens is independently connected to the water tank inside the equipment box.

[0011] The beneficial effects of this invention are as follows: The test chamber contains multiple test chambers separated by partitions. The partitions independently isolate the temperature, humidity, and light in each test chamber, ensuring that adjacent chambers do not affect each other. Each test chamber is electrically connected to the control panel and equipment box, and each chamber can be independently controlled. This allows for simultaneous stability testing of multiple different cosmetics, improving testing efficiency. The partitions are slidably connected to upper and lower sliding grooves, allowing the multiple test chambers within the chamber to independently conduct stability tests on different cosmetics under different test conditions and for different time periods. Alternatively, the partitions can be disassembled, combining the multiple test chambers into a large chamber, enabling simultaneous stability testing of multiple cosmetics under the same test conditions, further improving testing efficiency and the applicability of the test chamber.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] like Figure 1 and Figure 2As shown, this utility model discloses a device for testing the stability of cosmetics, including a housing 1 and a test chamber 3 and an equipment box 2 located vertically inside the housing 1. The test chamber 3 is equipped with a control panel 4, which contains a controller and operation buttons. The control panel 4 is electrically connected to the test chamber 3 and the equipment box 2. The equipment box 2 contains various cables, water pumps, water tanks, and water pipes. The control method of the control panel 4 and the structure of the equipment box 2 adopt existing technology, so they will not be described in detail.

[0021] like Figure 2 , Figure 4 and Figure 5 As shown, in a preferred embodiment, the inner cavity of the test chamber 3 is provided with multiple test chambers 5 separated by multiple partitions 8. For example, in this embodiment, three test chambers 5 are separated by two partitions 8. Of course, this utility model is not limited to three test chambers 5, but can also have two, four or other numbers of test chambers 5. Each test chamber 5 can be used to conduct cosmetic stability tests independently. To prevent adjacent test chambers 5 from affecting each other, the partitions 8 include two heat insulation layers 801 on both sides and a waterproof layer 802 and a light-shielding layer 803 located between the two heat insulation layers 801. This completely isolates the temperature, humidity and light between two adjacent test chambers 5. Thus, when a test chamber 5 conducts a cosmetic stability test, it is not affected by the adjacent test chambers 5.

[0022] Each test chamber 5 has an independent pull-out door 501 at its opening, which can seal the test chamber 5 to prevent it from being affected by the external environment. The bottom of each test chamber 5 has a filter screen 502 that communicates with the equipment box 2. Water can flow from the filter screen 502 into the water tank inside the equipment box 2. Each filter screen 502 is independently connected to the water tank inside the equipment box 2, thus the spaces below adjacent filter screens 502 are not connected. Therefore, when conducting cosmetic stability tests, the test chamber 5 is unaffected by adjacent test chambers 5.

[0023] like Figure 3 and Figure 4 As shown, in a preferred embodiment, each test chamber 5 is equipped with multiple humidifying heads 9, spray heads 10, ultraviolet lamps 11, and thermoelectric coolers 12. The humidifying heads 9, spray heads 10, and ultraviolet lamps 11 employ existing structures and will not be described in detail. The thermoelectric cooler 12 is used for cooling and heating within the test chamber 5 and is electrically connected to the control panel 4. The thermoelectric cooler 12 utilizes the thermoelectric effect to achieve cooling or heating, has no moving mechanical parts, operates quietly, and allows for precise temperature control. By controlling the direction and magnitude of the current flowing through the thermoelectric cooler 12, the degree of cooling and heating can be precisely controlled, and heat transfer is convenient. Each test chamber 5 is independently electrically connected to the control panel 4, and each test chamber 5 is individually controlled by the control panel 4.

[0024] In a preferred embodiment, the partition 8 is slidably connected between the top wall of the inner cavity of the test chamber 3 and two adjacent filters 502, thereby changing the size of the test space in the test chamber 5. Specifically, the top of the inner cavity of the test chamber 3 is provided with multiple upper sliding grooves 7 that match the partition 8, and a lower sliding groove 6 is provided between two adjacent filters 502. The partition 8 is slidably connected between the lower sliding groove 6 and the upper sliding groove 7. A removable baffle 301 is provided on the side of the test chamber 5 near the pull-out door 501. The removable baffle 301 abuts against the partition 8. It should be understood that the partition 8 can completely separate and seal adjacent test chambers 5, so that adjacent test chambers 5 do not affect each other.

[0025] When it is necessary to conduct stability tests on various cosmetics under different test conditions and for different time periods, the detachable baffle 301 can stably limit the partition 8 between the lower slide groove 6 and the upper slide groove 7, allowing multiple test chambers 5 to be tested individually, thus improving test efficiency. When it is necessary to conduct the same test conditions on multiple cosmetics, the partition 8 can be removed, allowing multiple test chambers 5 to be combined into one large chamber, enabling simultaneous stability tests on multiple cosmetics under the same test conditions, thus improving the test efficiency and applicability of the equipment.

[0026] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
