Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a constant temperature water bath device for cosmetics testing. Background Art

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are spread on any part of the human body surface, such as skin, hair, nails, lips and teeth, by smearing, spraying or other similar methods, for the purpose of cleaning, maintenance, beautification, modification and change of appearance, or correction of body odor and maintenance of good condition.

[0003] Constant temperature water bath is a common method for direct or auxiliary heating in experimental science fields such as biology, botany, physics, chemical engineering, medicine, and environmental protection. By subjecting experimental items to a water bath at a certain temperature and for a certain period of time, and then detecting changes in their properties, we can determine the temperature suitable for them and the storage time at that temperature. We can also determine the maximum temperature at which they can be stored while maintaining their original properties.

[0004] For example, the patent (CN214952930U) discloses a constant temperature water bath device for passivation experiments of opened cosmetics, including a constant temperature water bath box, the constant temperature water bath box is square in shape, a cosmetic experiment slot is provided in the middle of the top of the constant temperature water bath box, the slot surface of the cosmetic experiment slot is covered with a passivation support plate, the surface of the passivation support plate is provided with a plurality of strip-shaped water outlet holes, and an environment simulation base is installed at the bottom of the constant temperature water bath box. The beneficial effects of the utility model are: through the constant temperature water bath box, the cosmetic experiment slot and the passivation support plate, the cosmetics used for the passivation experiment are conveniently placed, and the rotating screw and the strip-shaped telescopic guide rail are provided on the surface of the culture dish through quantitative sampling. When the rotating screw is driven to move, the sleeve sleeved on the surface is telescopically operated up and down.

[0005] When using the above technology, it was found that the following technical problems exist in the prior art: the prior art drives the lifting nut and the passivation tray to adjust the displacement by rotating the screw, so it is not convenient to disassemble and clean the passivation tray, and the prior art uses an exciter to vibrate the excitation box, which will cause the cosmetic culture dish on the passivation tray to tilt and invert. In addition, the vibration of the excitation box in the prior art causes water to collide and adhere to the observation window, and the water mist generated by simulating a humid environment adheres to the observation window, resulting in the inability of the inspector to clearly observe the situation in the water temperature box. For this reason, we design a constant temperature water bath device for cosmetics testing to provide another technical solution to the above technical problems. Summary of the invention

The prior art uses an exciter to vibrate the excitation box, which will cause the cosmetic culture dish on the passivation support plate to tilt and turn upside down. In addition, the prior art causes water to collide and adhere to the observation window due to the vibration of the excitation box, and the water mist generated by simulating a humid environment adheres to the observation window, resulting in the inability of the inspection personnel to clearly observe the situation in the water temperature box.
