[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0039] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] During the process of applying makeup, in order to make the liquid foundation fit the skin better, people usually wet the powder puff with warm water or setting spray first, and then pick up the powder to apply makeup. During the process of wetting the powder puff, people generally wet the powder puff manually with water and then suck out the excess water, repeating this process until the humidity of the powder puff reaches the ideal humidity to facilitate the powder puff to pick up the liquid foundation.

[0042] However, this process is rather troublesome and time-consuming. Especially in scenarios where quick makeup application is required (such as daily commuting or emergency situations), the user experience is poor.

[0043] Therefore, the present invention proposes a humidity control device and a powder puff storage box, aiming to solve the technical problem that the existing method of wetting the powder puff is rather troublesome and time-consuming. In an embodiment of the present invention, referring to Figure 1 , the humidity control device includes:

[0044] A humidifying device 10;

[0045] A drying device 20;

[0046] A main control circuit 30, the main control circuit 30 is respectively connected to the controlled end of the humidifying device 10 and the controlled end of the drying device 20;

[0047] A humidity detection component 40, the output end of the humidity detection component 40 is electrically connected to the main control circuit 30, and the humidity detection component 40 is used to detect the humidity of the powder puff and output a corresponding humidity detection signal;

[0048] A trigger component 50, the trigger component 50 is electrically connected to the main control circuit 30, the trigger component 50 is used to output a trigger signal when triggered, and the main control circuit 30 is used to control the humidifying device 10 to humidify the powder puff / control the drying device 20 to dry the powder puff according to the trigger signal.

[0049] The main control circuit 30 is used to determine the humidity of the powder puff according to the humidity detection signal, and is also used to control the humidifying device 10 to humidify the powder puff to make the humidity of the powder puff reach the first preset humidity, or control the drying device 20 to dry the powder puff when receiving the trigger signal.

[0050] It should be noted that the first preset humidity is the ideal humidity set by the user according to their own needs. The powder puff can pick up the liquid foundation better at the first preset humidity.

[0051] In this embodiment, optionally, the triggering component 50 can be implemented by a DIP switch. The DIP switch has multiple independent switches, which respectively correspond to drying or humidifying. The user toggles the DIP switch according to the requirement, and the DIP switch outputs an electrical signal to the main control circuit 30 according to the toggled switch. The main control circuit 30 controls the humidifying device 10 to humidify the powder puff to the first preset humidity, or controls the drying device 20 to dry the powder puff according to the electrical signal output by the DIP switch.

[0052] Optionally, the triggering component 50 can also be implemented by a rotary switch. By rotating the knob, different function modes can be selected, and the position of the knob is read as a triggering signal by the main control circuit 30 to control the humidifying device 10 or the drying device 20.

[0053] In this embodiment, the humidity detection component 40 can be implemented by a capacitive humidity sensor or a resistive humidity sensor. The humidity detection component 40 can detect the humidity of the powder puff by directly contacting the surface of the powder puff to improve the accuracy of humidity detection. Considering that direct contact may contaminate the humidity detection component 40 due to the cosmetic residue on the powder puff, the humidity detection component 40 can also detect the humidity of the powder puff in a non-contact manner, that is, the humidity detection component 40 is arranged around the powder puff, and the humidity detection component 40 determines the humidity of the powder puff by detecting the humidity in the air.

[0054] In this embodiment, the humidifying device 10 can be implemented by a spray humidifier. The spray humidifier forms water mist by spraying water at high pressure through a micro pump. The water mist can evenly cover the powder puff, so that the humidity distribution of the powder puff is uniform. The humidifying device 10 can be arranged on the inner wall of the lid of the powder puff storage box, so that when the lid of the powder puff storage box is closed, the water mist sprayed by the humidifying device 10 covers the powder puff from top to bottom, ensuring that all parts of the powder puff can contact the water mist, and the top-down water mist spraying can better penetrate into the powder puff, especially the sponge powder puff with a porous structure.

[0055] In this embodiment, optionally, the drying device 20 can be implemented by multiple flexible electric heating films. The multiple flexible electric heating films are distributed on the inner wall of the powder puff storage box, and the powder puff is dried by radiating heat. Optionally, the drying device 20 can also be implemented by a small fan. The powder puff storage box has an air inlet and an air outlet. The small fan is arranged in the air inlet and is used to blow external air into the powder puff storage box. After passing through the powder puff, it is discharged from the air outlet, forming a continuous air flow cycle. The continuous air flow cycle can effectively take away the moisture on the surface of the powder puff, thereby realizing drying.

[0056] In this embodiment, the main control circuit 30 can be implemented by a main controller, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), an SOC (System On Chip), etc.

[0057] In this embodiment, the humidity control device of the present invention includes a humidifying device 10, a drying device 20, a main control circuit 30, a humidity detection component 40, and a trigger component 50. The main control circuit 30 is respectively connected to the controlled end of the humidifying device 10, the controlled end of the drying device 20, the trigger component 50, and the output end of the humidity detection component 40. The humidity detection component 40 is used to detect the humidity of the powder puff and output a humidity detection signal. The trigger component 50 is used to output a trigger signal when triggered. The main control circuit 30 is used to determine the humidity of the powder puff according to the humidity detection signal output by the humidity detection component 40, and is also used to control the humidifying device 10 to humidify the powder puff / control the drying device 20 to dry the powder puff when receiving the trigger signal, so that the humidity of the powder puff reaches a first preset humidity. With such a setting, the humidity control device of the present invention realizes the automatic and precise adjustment of the humidity of the powder puff, and solves the problems of cumbersome manual operation and long time consumption in the traditional method. In practical applications, when the user needs to wet the powder puff, only need to trigger the trigger component 50, and the humidity control device of the present invention can automatically complete the humidity adjustment of the powder puff, so that the humidity of the powder puff reaches the ideal humidity, without manual water dipping or blotting, which can save a lot of time for the user.

[0058] In addition, when the main control circuit receives the trigger signal and the humidity of the powder puff is greater than the first preset humidity, it can control the drying device to partially dry the powder puff, so that the humidity of the powder puff drops to the first preset humidity, without completely drying the powder puff before humidifying, thus simplifying the process of adjusting the humidity of the powder puff.

[0059] In addition, the humidity control device further includes a display component and a buzzer. Both the display component and the buzzer are connected to the main control circuit 30. The main control circuit 30 is used to control the display component to display the current humidity of the powder puff, as well as the working state of the humidifying device 10 or the drying device 20. The main control circuit 30 is used to control the buzzer to work when the humidity of the powder puff reaches the first preset humidity, so as to prompt the user that the humidity adjustment of the powder puff is completed.

[0060] It should be noted that the powder puff can achieve a better effect of grasping liquid foundation only when the humidity on its surface and inside reaches the ideal humidity. During the process of humidifying the powder puff, since water cannot penetrate into the inside of the powder puff immediately, there will be a situation where the humidity on the surface of the powder puff reaches the ideal humidity but its inside is still dry. It takes a certain amount of time for water to penetrate into the inside of the powder puff, which will increase the time spent on wetting the powder puff to the ideal humidity.

[0061] In this regard, in an embodiment of the present invention, with reference to Figure 2 , the humidity control device further includes:

[0062] An extrusion assembly 60, the extrusion assembly 60 is connected to the main control circuit 30, and the main control circuit 30 is used to control the extrusion assembly 60 to extrude the powder puff when the humidity of the powder puff reaches a first preset humidity, so that water penetrates into the inside of the powder puff.

[0063] In this embodiment, optionally, the extrusion assembly 60 can be implemented by an extrusion plate having the same size as the powder puff. The extrusion plate is provided on the upper inner wall of the lid of the powder puff storage box and is driven by a motor. The main control circuit 30 is used to control the start and stop of the motor. When the humidity of the powder puff reaches the first preset humidity, the main control circuit 30 controls the motor to drive the extrusion plate to extrude the powder puff from top to bottom, so as to extrude the water on the surface of the powder puff to penetrate into the inside of the powder puff, ensuring uniform humidity distribution inside and on the surface of the powder puff and improving the effect of the powder puff grasping liquid foundation.

[0064] Optionally, the extrusion assembly 60 can also be implemented by an airbag. The airbag is provided on the upper inner wall of the lid of the powder puff storage box and is driven by an air pump. The main control circuit 30 controls the air pump to work to control the inflation of the airbag. When the airbag inflates, it will extrude the powder puff, so as to extrude the water on the surface of the powder puff to penetrate into the inside of the powder puff, ensuring uniform humidity distribution inside and on the surface of the powder puff and improving the effect of the powder puff grasping liquid foundation.

[0065] Through the above settings, the humidity control device of the present invention squeezes water into the inside of the powder puff by extrusion, shortening the time spent on making the humidity distribution on the surface and inside of the powder puff uniform, and avoiding the situation where the surface of the powder puff is wet but its inside is still dry.

[0066] Furthermore, since the water on the surface of the powder puff is squeezed into the inside of the powder puff, the water on the surface of the powder puff decreases, resulting in the humidity on the surface of the powder puff being lower than the first preset humidity. Therefore, when the extrusion assembly 60 stops working and the main control circuit 30 detects that the humidity on the surface of the powder puff is lower than the first preset humidity, it continues to control the humidifying device 10 to humidify the powder puff until the humidity of the powder puff reaches the first preset humidity.

[0067] It should be considered that in order to accelerate the efficiency of humidifying the powder puff, the user may choose to increase the power of the humidifying device 10 for spraying water (such as increasing the spray amount or raising the spraying speed), thereby improving the humidifying efficiency of the humidifying device 10. However, a relatively fast water spraying power may cause the humidity of the powder puff to exceed the ideal humidity range, thus affecting the user experience.

[0068] In this regard, in the present embodiment, when the main control circuit 30 receives the trigger signal and the humidity of the powder puff is less than the second preset humidity, it controls the humidifying device 10 to humidify the powder puff so that the humidity of the powder puff reaches the second preset humidity.

[0069] The main control circuit 30 is used to, when the humidity of the powder puff reaches the second preset humidity, control the squeezing assembly 60 to squeeze the powder puff, reduce the power of the humidifying device 10, and control the humidifying device 10 to humidify the powder puff so that the humidity of the powder puff reaches the first preset humidity.

[0070] Wherein, the second preset humidity is less than the first preset humidity.

[0071] Through the above settings, when the humidity of the powder puff in the humidity control device of the present invention is close to the ideal humidity, the squeezing assembly 60 is first used to squeeze the powder puff to ensure uniform distribution of the surface humidity and internal humidity of the powder puff, and then the low-power humidifying device 10 is controlled to humidify the powder puff to ensure that the humidity of the powder puff gradually reaches the ideal humidity.

[0072] It can be understood that when the humidity of the powder puff is greater than the first preset humidity after being humidified by the humidifying device 10, the main control circuit 30 controls the drying device 20 to dry the powder puff so that the humidity of the powder puff is reduced to the first preset humidity, thereby realizing precise humidity adjustment.

[0073] In an embodiment of the present invention, referring to Figure 3 , the humidity control device includes:

[0074] A parameter input component 70, the parameter input component 70 is electrically connected to the main control circuit 30, and the main control circuit 30 is used to determine the value of the preset humidity according to the parameter signal output by the parameter input component 70.

[0075] In this embodiment, optionally, the parameter input component 70 can be implemented by a potentiometer. The two ends of the potentiometer are respectively connected to the positive power supply and the ground, and the middle pin is connected to the ADC input end of the main control circuit 30. The main control circuit 30 reads the voltage value of the middle pin of the potentiometer and converts it into a humidity parameter. The humidity range (such as 0%-100%) is marked beside the potentiometer knob or sliding rod for the user to adjust the potentiometer according to actual needs. After receiving the humidity parameter, the main control circuit 30 determines the preset humidity set by the user.

[0076] Optionally, the parameter input component 70 can also be implemented using multiple buttons. For example, two buttons (such as "increase" and "decrease" buttons) are used to adjust the humidity parameter respectively. The main control circuit 30 detects whether the button is pressed by periodically scanning the status of the GPIO pin. Each time the "increase" button is pressed, the preset humidity is increased by 1%, and each time the "decrease" button is pressed, the preset humidity is decreased by 1%.

[0077] The present invention also provides a powder puff storage box, which includes a powder puff storage box body and the humidity control device as described above.

[0078] It should be noted that since the powder puff storage box of the present invention is based on the above humidity control device, the embodiments of the powder puff storage box of the present invention include all the technical solutions of all the embodiments of the above humidity control device, and the achieved technical effects are exactly the same, which will not be elaborated here.

[0079] It should be noted that a powder puff storage box is usually used to place multiple powder puffs. In the case where the storage and drying of multiple powder puffs share the same space, when drying one powder puff, other already dried powder puffs may also be repeatedly dried. Repeated drying will cause the powder puff material to age, harden or crack, especially for sponge powder puffs, thus reducing the use experience.

[0080] In this regard, in an embodiment of the present invention, the powder puff storage box body includes a first powder puff storage area and a second powder puff storage area. The first powder puff storage area is used to store powder puffs, and the humidity control device is arranged in the second powder puff storage area to humidify / dry the powder puffs placed in the second powder puff storage area.

[0081] Through the above settings, the first powder puff storage area is used to provide powder puffs that can be used at any time. Users can quickly access them without additional operations. Moreover, the first powder puff storage area is separated from the humidity control device, and the dry powder puffs will not be affected by the humidifying or drying operations, avoiding the aging, hardening or cracking of the powder puffs caused by repeated drying and extending their service life.

[0082] Further, in this embodiment, referring to Figure 4 , the humidity control device further includes:

[0083] A pressure sensor 80, which is arranged at the bottom of the second powder puff storage area. The output end of the pressure sensor 80 is electrically connected to the main control circuit 30. The pressure sensor 80 is used to detect the pressure it receives and output a corresponding pressure detection signal;

[0084] The main control circuit 30 is configured to determine the pressure received by the pressure sensor 80 according to the pressure detection signal, start the first timing when the pressure received by the pressure sensor 80 is less than the preset pressure, and stop the first timing when the pressure received by the pressure sensor 80 is greater than or equal to the preset pressure;

[0085] The main control circuit 30 is further configured to control the drying device 20 to dry the second powder puff storage area when the duration of the first timing is greater than the first preset duration.

[0086] It should be noted that when the powder puff is placed in the second powder puff storage area, the pressure sensor 80 receives the pressure from the powder puff, so that the pressure it receives is greater than or equal to the preset pressure, and when the powder puff is not placed in the second powder puff storage area, the pressure received by the pressure sensor 80 is less than the preset pressure.

[0087] Through the above settings, when the powder puff is not in the second powder puff storage area for a long time, the humidity control device dries the second powder puff storage area to prevent water droplets from staying for a long time and breeding bacteria and molds.

[0088] It should be considered that in practical applications, there may be a situation where the user forgets to take out the powder puff after humidifying it. If the powder puff is stored in a humid state for a long time, it will cause mold growth, thus affecting the user experience.

[0089] In this regard, in an embodiment of the present invention, the main control circuit 30 is configured to start the second timing when receiving the trigger signal to control the humidifying device 10 to humidify the powder puff / control the drying device 20 to dry the powder puff so that the humidity of the powder puff reaches the first preset humidity. The main control circuit 30 is further configured to stop the second timing when the pressure received by the pressure sensor 80 is less than the preset pressure;

[0090] The main control circuit 30 is further configured to control the drying device 20 to dry the powder puff when the duration of the second timing is greater than the second preset duration.

[0091] Through the above settings, after the powder puff storage box of the present invention adjusts the humidity of the powder puff, it starts the second timing. When the user forgets to take out the powder puff for use, the duration of the second timing is greater than the second preset duration. At this time, the powder puff storage box of the present invention controls the drying device 20 to dry the powder puff, preventing the powder puff from being stored in a high humidity state for a long time and causing mold growth, thereby improving the user experience.

[0092] In an embodiment of the present invention, the powder puff storage box further includes: a box cover, and the box cover is detachably connected to the powder puff storage box body through a snap structure, a threaded connection or a magnetic attraction structure.

[0093] It should be noted that the detachable connection allows the user to completely remove the lid for easy cleaning or replacement of internal components; the hinged connection enables the lid to rotate around a fixed axis for convenient opening and closing operations.

[0094] In this embodiment, the humidity control device further includes: a Hall sensor and a permanent magnet. The Hall sensor is electrically connected to the main control circuit 30. The permanent magnet is provided on the powder puff storage box body, and the Hall sensor is provided on the lid. The Hall sensor is used to detect the magnetic field around itself and output a corresponding magnetic field signal according to the magnetic field strength. When the main control circuit 30 determines that the magnetic field around the Hall sensor is greater than the preset magnetic field based on the magnetic field signal, it indicates that the distance between the Hall sensor and the permanent magnet is relatively close, that is, it is determined that the lid has been closed; when it is determined that the magnetic field around the Hall sensor is less than the preset magnetic field based on the magnetic field signal, it indicates that the distance between the Hall sensor and the permanent magnet is relatively far, that is, it is determined that the lid has not been closed.

[0095] In this embodiment, when the main control circuit 30 determines that the lid has not been closed and receives a trigger signal, it chooses not to control the humidifying device 10 to humidify the powder puff / control the drying device 20 to dry the powder puff, to avoid that some components provided on the lid, such as the humidifying device 10, cannot process the powder puff when the lid is not closed. The main control circuit 30 controls the humidifying device 10 to humidify the powder puff / control the drying device 20 to dry the powder puff only when it determines that the lid has been closed and receives a trigger signal.

[0096] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
