Description

Technical Field

[0001] The utility model relates to the technical field of mirrors, in particular to a portable anti-fog makeup mirror. Background Art

[0002] Makeup mirrors are commonly used daily necessities in life, especially for women. When applying makeup, a relatively clear and bright mirror surface is often required to facilitate observing the makeup effect at any time during makeup application, so that the makeup can be more perfect and delicate. However, in seasons with relatively low temperatures such as winter, the mirror often gets fogged up due to the low temperature. When encountering relatively hot gas, such as the gas exhaled from the mouth, or being affected by the hot water temperature when used in the bathroom, due to the temperature difference effect, the mirror surface will fog up, resulting in the mirror surface becoming blurred and affecting the use. It often needs to be wiped, which is time-consuming and troublesome.

[0003] In related technologies, usually a self-controlled temperature electric heating belt is arranged inside the mirror, and a rotary switch for controlling the self-controlled temperature electric heating belt is arranged outside the mirror. When the mirror gets fogged up, the self-controlled temperature electric heating belt is started through the rotary switch to increase the temperature of the mirror, thereby eliminating the fog on the mirror surface. However, the power requirement of the self-controlled temperature electric heating belt is relatively high, and it cannot be adapted to portable mirrors for use. Moreover, it cannot automatically sense the temperature and adjust the heating temperature according to the real-time air temperature to achieve the effects of energy saving and avoiding scalding.

[0004] Therefore, it is urgent to solve the problem that portable mirrors cannot automatically sense the temperature and adjust the heating temperature according to the real-time air temperature. Content of the Utility Model

[0005] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides a portable anti-fog makeup mirror, which solves the problem that portable mirrors cannot automatically sense the temperature and adjust the heating temperature according to the real-time air temperature.

[0006] The technical effects to be achieved by the utility model are realized through the following technical solutions:

[0007] The utility model provides a portable anti-fog makeup mirror, including:

[0008] A mirror frame;

[0009] A heating module, installed on one side of the mirror surface close to the mirror frame, including a heating sheet and a controller;

[0010] A temperature sensing device, connected to one side of the heating sheet close to the mirror frame, for sensing the actual temperature of the heating sheet; and

[0011] A mirror surface, connected to the periphery of the mirror frame.

[0012] In some implementation manners, the heating sheet is provided with a plurality of heating zones.

[0013] In this implementation, the user can control the area where the heating plate emits heat energy according to actual needs, which is more conducive to saving energy consumption.

[0014] In some implementations, the surface of the heating plate has a plurality of heating wires, and the plurality of heating wires are arranged in a circuitous manner to form a heating surface. The spacing distance between the plurality of heating wires is any value between 0.5 mm and 10 mm, and the width of the heating wires is any value between 0.5 mm and 10 mm.

[0015] In some implementations, the temperature sensing device is a temperature sensor.

[0016] In some implementations, a placement area is formed inside the lens frame, and an installation area for installing the LED light group is formed between the periphery of the lens frame and the placement area.

[0017] In this implementation, the LED light group is installed in the installation area formed between the periphery of the mirror frame and the placement area. The installation area serves to limit the LED light group, so that the LED light group is more fixedly installed inside the mirror frame, which facilitates installation and makes the overall structure more compact.

[0018] In some implementations, the LED light group is a three-color light.

[0019] In some implementations, a control panel for installing a temperature control switch and a light group switch extends from the edge of the mirror frame.

[0020] In some implementations, a charging port is provided on one side of the control panel, and a protective block for clamping the charging port is connected to an edge of the charging port.

[0021] In some implementations, a buffer is provided at the connection between the periphery of the mirror frame and the mirror surface.

[0022] In this implementation, when the mirror is installed on the frame, the frame and the mirror respectively generate a pressing force on the buffer to make the connection between the frame and the mirror tighter, thereby improving the overall structural stability and avoiding the problem of the mirror detaching from the frame and affecting use.

[0023] In some implementations, the mirror frame includes a bottom frame and an annular fixing frame, wherein the annular fixing frame is respectively connected to the periphery of the bottom frame and a side of the buffer member facing away from the bottom frame, so as to fix the buffer member on the bottom frame.

[0024] In some implementations, a bracket assembly is further included, which includes a connecting member and a supporting member, one end of the connecting member is connected to a side of the frame facing away from the heating plate through a first pivot, and the other end is connected to the supporting member through a second pivot.

[0025] In this implementation, the support member enables the spectacle frame to stand on a plane such as a tabletop, so that the portable anti-fog makeup mirror stands on a plane such as a tabletop. Rotate the connecting member and / or the spectacle frame to rotate the first pivot and / or the second pivot, so as to adjust the rotation angles of the connecting member and the spectacle frame, and further adjust the placement angle of the portable anti-fog makeup mirror, making it more convenient to use.

[0026] In summary, the present utility model has at least the following advantages:

[0027] For the portable anti-fog makeup mirror provided by the present utility model, a temperature sensing device and a heating module are arranged inside the spectacle frame. The temperature sensing device can obtain the temperature of the makeup mirror and feedback the temperature to the controller, so as to control the heating sheet to emit heat energy to remove the fog on the mirror surface. When the temperature of the makeup mirror reaches the preset maximum temperature, the heating sheet stops heating, avoiding the problem of scalding the user due to excessive heating temperature while removing the fog, and also saving energy consumption. In this way, the problem that a portable mirror cannot automatically sense the temperature and adjust the heating temperature according to the real-time temperature is solved.

[0049] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are some but not all of the embodiments of the present utility model.

[0050] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0051] Embodiment 1:

[0052] Please refer to the attached Figures 1 - 2 , the portable anti-fog makeup mirror of the present utility model includes a mirror frame 1, a heating sheet 21, a temperature sensing device 3, and a mirror surface 4.

[0053] Among them, please refer to Figure 1 , Figure 1 which shows the structural relationship between the heating sheet 21, the temperature sensing device 3 and the mirror surface 4 in the embodiment of the present utility model. Specifically, the heating module 2 is installed on the side of the mirror surface 4 close to the mirror frame 1, and includes a heating sheet 21 and a controller 22; the temperature sensing device 3 is connected to the side of the heating sheet 21 close to the mirror frame 1 for sensing the actual temperature of the heating sheet 21; the mirror surface 4 is connected to the periphery of the mirror frame 1.

[0054] In this embodiment, the heating module 2 is installed on the side of the mirror surface 4 close to the mirror frame 1, and the heating module is closely attached to the lens 4, so as to better conduct heat, and at the same time the overall structure is more compact, reducing the occupied space, making the makeup mirror thinner and lighter, thus ensuring the portability of the makeup mirror; the heating sheet 21 is used to heat the makeup mirror to remove the fog surface, the controller 22 is used to execute the anti-fog method, and the temperature sensing device 3 is used to sense and obtain the temperature of the mirror surface 4. When the defogging instruction is started, the controller 22 will control the heating sheet 21 to emit heat energy to increase the temperature of the makeup mirror, thereby eliminating the fog generated on the mirror surface 4 due to the hot air exhaled by the human body under the action of the temperature difference, achieving the defogging effect and ensuring the clarity of the mirror surface 4. Preferably, after the temperature sensing device 3 obtains the temperature of the mirror surface 4, it feeds back the temperature to the controller 22. The controller 22 can match the preset heating power according to the temperature of the mirror surface 4 and control the heating sheet 21 to emit heat energy. During the heating process, the temperature sensing device 3 continuously obtains the temperature of the mirror surface 4 and / or the heating sheet 21. When the temperature of the mirror surface 4 and / or the heating sheet 21 reaches the preset maximum temperature, it is determined that the defogging is completed, and the controller 22 controls the heating sheet 21 to stop heating, avoiding excessive energy consumption while completing the defogging. Of course, the heating sheet 21 can also be controlled to emit heat energy manually, and the heating function of the heating sheet 21 can be turned off after removing the fog on the mirror surface 4 to achieve the effect of defogging and energy saving.

[0055] The above-mentioned portable anti-fog makeup mirror is provided with a temperature sensing device 3 and a heating module 2 inside the mirror frame 1. The temperature sensing device 3 can obtain the temperature of the makeup mirror and feedback the temperature to the controller 22, thereby controlling the heating sheet 21 to dissipate heat energy to remove the fog on the mirror surface 4. When the temperature of the makeup mirror reaches the preset maximum temperature, the heating sheet 21 stops heating, which not only removes the fog but also avoids the problem of scalding the user due to excessive heating temperature, and also saves energy consumption. In this way, the problem that a portable mirror cannot automatically sense the temperature and adjust the heating temperature according to the actual situation is solved.

[0056] In some preferred embodiments, please refer to Figure 2 , Figure 2 which schematically shows the specific structure of the heating sheet 21 in the embodiment of the present invention. Specifically, the heating sheet 21 is provided with a plurality of heating zones 211. The user can control the area where the heating sheet 21 dissipates heat energy according to actual needs, which is more conducive to saving energy consumption. It can be understood that when the exhaled gas of the human body causes fogging in a small area on the mirror surface 4, the heating zone 211 of the heating sheet 21 can be adjusted to remove the fog in the small area, ensuring the clarity of the mirror surface 4 while achieving a better energy-saving effect.

[0057] In some preferred embodiments, please refer to Figure 3 , the surface of the heating sheet 21 has a plurality of heating wires 212, and the plurality of heating wires 212 form a heating surface by winding circuitously. The spacing distance D1 between the plurality of heating wires 212 is preferably any value between 0.5 mm and 10 mm, and the width D2 of the heating wire 212 is preferably any value between 0.5 mm and 10 mm. The heating wires 212 are evenly spaced on the heating sheet 21, making the heating temperature of the heating sheet 21 more uniform, thereby improving the heating effect of the heating sheet 21. Further, the heat energy generated between the heating wires 212 can interact to produce a stronger heating effect. And because the heating wires 212 are spaced on the heating sheet 21, the defogging effect can be achieved without heating the entire heating sheet 21, which saves more energy consumption. The circuitous winding method makes the heating wires 212 evenly distributed on the heating sheet 21, avoiding the generation of dead corners that may cause uneven heating and thus affecting the defogging effect. Preferably, the plurality of heating wires 212 can form a heating surface by means of serpentine, annular, curved, regular and / or irregular winding methods.

[0058] In some more preferred embodiments, the temperature sensing device 3 is a temperature sensor. It is used to obtain the temperature of the makeup mirror in real time and control the heating sheet 21 to dissipate heat energy to achieve a defogging effect. Moreover, it is convenient for installation and / or disassembly, improving the installation and maintenance efficiency; it occupies less space, further ensuring the portability of the makeup mirror.

[0059] Embodiment 2:

[0060] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the portable anti-fog makeup mirror of the present utility model. Please refer to the attached Figures 4 - 5 .

[0061] Among them, please refer to Figure 4 . Figure 4 which shows the structural relationship between the LED lamp group 12 and the mirror frame 1 in the embodiment of the present utility model. Specifically, a placement area 11 is formed inside the mirror frame 1, and an installation area 13 for installing the LED lamp group 12 is formed between the periphery of the mirror frame 1 and the placement area 11.

[0062] In this embodiment, the LED lamp group 12 is installed in the installation area 13 formed between the periphery of the mirror frame 1 and the placement area 11. The installation area 13 plays a role in limiting the LED lamp group 12, making the LED lamp group 12 more fixedly installed inside the mirror frame 1, facilitating installation and making the overall structure more compact; and it also avoids the problem that the heating sheet 21 and the LED lamp group 12 interfere with each other, thereby affecting the normal operation of the heating sheet 21 and / or the LED lamp group 12.

[0063] In some preferred embodiments, the LED lamp group 12 is a three-color lamp. The user can control the LED lamp group 12 to emit light of different colors, which is more suitable for different usage scenarios. It can be understood that in a dim scene, in order not to disturb others, warm yellow flexible light can be used to achieve the lighting effect.

[0064] In some preferred embodiments, please refer to Figure 5 . Figure 5 which shows the structural relationship between the temperature control switch 14, the lamp group switch 15 and the control board 16 in the embodiment of the present utility model. Specifically, a control board 16 for installing the temperature control switch 14 and the lamp group switch 15 extends from the edge of the mirror frame 1. The user can operate the temperature control switch 14 to make the heating sheet 21 start to emit heat energy and / or turn off the heating function of the heating sheet 21; the user can operate the lamp group switch 15 to make the LED lamp group 12 emit light and / or turn off the LED lamp group 12. It can be understood that by operating the temperature control switch 14, the heating temperature and / or heating area of the heating sheet 21 can also be adjusted according to the actual defogging requirements to eliminate the foggy surface; by operating the lamp group switch 15, the light color and / or light intensity of the LED lamp group 12 can be adjusted according to different usage scenarios, which is more suitable for different usage requirements.

[0065] In some more preferred embodiments, a charging port 161 is provided on one side of the control panel 16, and a protective block 162 for snapping into the charging port 161 is connected to the edge of the charging port 161. When the portable anti-fog cosmetic mirror is not charged, the protective block 162 is snapped into the charging port 161 to play a waterproof and dustproof role, thereby preventing the charging port 161 from being affected by dust, water vapor and other substances, causing charging failures; when charging, the protective block 162 is connected to the edge of the charging port 161 through a flexible connecting line to avoid loss and interference with charging.

[0066] Embodiment 3:

[0067] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the portable anti-fog cosmetic mirror of the utility model. Figures 6 - 9 .

[0068] Please combine Figure 6 and Figure 7 , Figure 6 and Figure 7 The schematic diagram shows the structural relationship between the buffer 17 and the lens frame 1 and the mirror surface 4 in the embodiment of the utility model. Specifically, the buffer 17 is provided at the connection between the periphery of the lens frame 1 and the mirror surface 4.

[0069] In this embodiment, when the mirror surface 4 is mounted on the frame 1, the frame 1 and the mirror surface 4 respectively exert a pressing force on the buffer 17, so that the connection between the frame 1 and the mirror surface 4 is more firmly connected, thereby improving the overall structural stability and preventing the mirror surface 4 from being separated from the frame 1, thereby affecting the use. At the same time, the buffer 17 also plays a buffering role to protect the mirror surface 4 and prevent the mirror surface 4 from being broken. Preferably, the buffer 17 completely covers the periphery of the mirror surface 4, so that the buffering effect and the fastening effect are more superior.

[0070] In some preferred embodiments, see Figure 8 , Figure 8 The schematic diagram shows the structural relationship between the buffer 17 and the bottom frame 18 and the annular fixing frame 19 in the embodiment of the utility model. Specifically, the mirror frame 1 includes the bottom frame 18 and the annular fixing frame 19, and the annular fixing frame 19 is connected to the periphery of the bottom frame 18 and the side of the buffer 17 away from the bottom frame 18, so as to fix the buffer 17 on the bottom frame 18. The annular fixing frame 19 fixes the buffer 17 on the bottom frame 18, thereby fixing the mirror surface 4 in the bottom frame 18, improving the compactness of the overall structure and further ensuring the reliability of the overall structure.

[0071] Furthermore, the annular fixing frame 19 is screwed to the periphery of the bottom frame 18 by bolts, so as to facilitate the installation and / or removal of the mirror surface 4, the heating plate 21 and the temperature sensing device 3 and other internal components of the frame 1, so as to improve the installation and maintenance efficiency. It can be understood that the annular fixing frame 19 can also be connected to the periphery of the bottom frame 18 by means of snap connection, inlay connection, etc.

[0072] In some more preferred embodiments, see Figure 9 , Figure 9 The diagram shows the structural relationship between the bracket assembly 5 and the mirror frame 1 in the embodiment of the utility model. Specifically, the portable anti-fog makeup mirror further includes a bracket assembly 5, which includes a connecting member 51 and a supporting member 52. One end of the connecting member 51 is connected to the side of the mirror frame 1 away from the heating plate 21 through a first pivot 53, and the other end is connected to the supporting member 52 through a second pivot 54. The supporting member 52 enables the mirror frame 1 to stand on a plane such as a desktop, so that the portable anti-fog makeup mirror can stand on a plane such as a desktop. The connecting member 51 and / or the mirror frame 1 are rotated to rotate the first pivot 53 and / or the second pivot 54 to adjust the rotation angle of the connecting member 51 and the mirror frame 1, thereby adjusting the placement angle of the portable anti-fog makeup mirror, which is more convenient to use.

[0073] Furthermore, the connecting member 51 is retractably connected between the frame 1 and the supporting member 52 to push the frame 1 and / or the supporting member 52 so that the frame 1 is closely attached to the supporting member 52, making it easier to store and carry.

[0074] Embodiment 4:

[0075] Figure 10 The flowchart of an embodiment of the anti-fog method of the portable anti-fog cosmetic mirror of the utility model is shown. Figure 10 As shown, based on the portable anti-fog cosmetic mirror, the method includes the following steps:

[0076] S110, the controller responds to the defogger start instruction and sends a heating signal to control the heating plate to heat the mirror surface to a maximum preset temperature and then stop heating.

[0077] Among them, when the mirror is fogged, the user triggers the defog function. After receiving the command of the defog function, the controller transmits a heating signal to the heating plate to control the heating plate to dissipate heat energy. When the temperature sensing device senses that the mirror has reached the preset maximum temperature, the temperature sensing device automatically feeds back a stop heating signal to the controller. After receiving the command to stop heating, the controller transmits the command to the heating plate to control the heating plate to stop heating; thereby eliminating the fog generated on the mirror surface to make the mirror surface clearer.

[0078] Of course, the heating function can also be stopped by manual triggering. After receiving the instruction to stop the heating function, the controller transmits a stop heating signal to the heating plate to control the heating plate to stop heating, thereby achieving energy saving effect.

[0079] In other embodiments, when the temperature sensing device senses that the temperature of the mirror surface is lower than the preset minimum temperature, it automatically feeds back a heating signal to the controller. After receiving the heating instruction, the controller transmits the heating signal to the heating sheet to control the heating sheet to dissipate heat energy.

[0080] S120. When it is detected that the temperature of the mirror surface is lower than the first preset temperature, a heating signal is sent again to heat the mirror surface.

[0081] Among them, when the temperature sensing device senses that the temperature of the mirror surface is lower than the first preset temperature, it feeds back a heating signal to the controller. After receiving the heating instruction, the controller transmits the heating signal to the heating sheet to control the heating sheet to dissipate heat energy, eliminate the foggy surface and save energy consumption at the same time.

[0082] Preferably, the highest preset temperature is 35°C - 38°C, and the first preset temperature is 31°C - 34°C.

[0083] In some embodiments, the highest preset temperature is 35°C and the first preset temperature is 32°C. When the temperature of the mirror surface reaches 35°C, the heating sheet stops heating. When the temperature of the mirror surface gradually cools down to 32°C, the controller controls the heating sheet to heat again. It can be understood that the highest preset temperature and the first preset temperature are related to energy consumption. The larger the temperature value of the highest preset temperature, the higher the energy consumption required for heating. Therefore, by setting the first preset temperature, the temperature difference between the temperature of the mirror surface and the highest preset temperature is within a controllable range, and the heating sheet is controlled to heat within this temperature range, so as to achieve the purpose of saving energy consumption.

[0084] In step S110, when sending a heating signal to control the heating sheet to heat the mirror surface to the highest preset temperature, it further includes:

[0085] Collect the actual temperature of the mirror surface;

[0086] Calculate the temperature difference between the actual temperature and the highest preset temperature;

[0087] According to the temperature difference, adjust the heating signal to control the heating sheet to heat the mirror surface.

[0088] In some embodiments, the actual temperature of the mirror surface is collected by a temperature sensing device and fed back to the controller. The controller calculates the temperature difference between the actual temperature and the highest preset temperature, and adjusts the heating signal according to the obtained temperature difference, thereby controlling the heating sheet to heat the mirror surface. Preferably, the heating signal is the heating power. It can be understood that in some embodiments, in order to have a better defogging experience without increasing energy consumption, the heating power can be set to adjust the defogging speed. For example, when the temperature difference is large, the heating power can be increased; when the temperature difference is small, the heating power can be decreased. In this way, by adjusting the heating power according to the temperature difference, the effect of defogging with the lowest energy consumption can be achieved, energy consumption can be saved, and the service life of the portable anti-fog makeup mirror can be extended.

[0089] Furthermore, the heating signal can control the heating power by controlling the current and voltage, and can also control the conduction frequency and duration of the heater in a manner similar to the PWM signal, so as to control the total heating amount per unit time.

[0090] Please refer to Figure 11 , Figure 11 which shows a schematic flowchart of the steps after step 110 of the anti-fog method of the portable anti-fog makeup mirror provided by the present invention.

[0091] In step S110, after sending a heating signal to control the heating sheet to heat the mirror surface to the highest preset temperature and then stopping heating, the following steps are further included:

[0092] S210. Detect the fogging condition of the mirror surface. After receiving the fogging signal of the mirror surface, record the current temperature of the mirror surface as the fogging temperature through the temperature sensing device.

[0093] Among them, after the controller stops heating, it continuously detects the fogging condition of the mirror surface. When it detects that the mirror surface is fogged, the controller transmits the fogging signal to the temperature sensing device. After receiving the fogging signal, the temperature sensing device obtains the current temperature and records this temperature as the fogging temperature. It can be understood that there are various means to detect the fogging condition. For example, the condensation condition on the mirror surface can be judged by a humidity sensor, or an image acquisition device can be set on the back of the mirror to judge parameters such as the blurriness and contrast of the acquired image, and finally determine the fogging condition. Of course, in some scenarios with low power requirements, such as in a portable scenario powered by a battery, in order to improve the battery life, the fogging condition can also be detected by setting a trigger button to collect manual operations, so as to minimize the additional power consumption generated by the system due to the need for external sensing devices. For example, after the mirror surface is fogged, the user operates to send a fogging signal. After receiving the instruction for the defogging function, the controller determines that the mirror surface is fogged and simultaneously transmits the fogging signal to the temperature sensing device to record the fogging temperature. This method can accurately judge the fogging state of the mirror surface in different temperature and humidity environments.

[0094] S220. The controller obtains the preset compensation temperature, and sets the target heating temperature by combining the fogging temperature and the preset compensation temperature.

[0095] Among them, after the controller detects that the mirror surface fogs up again and / or receives the defogging instruction again, it obtains the preset compensation temperature, combines the fogging temperature recorded by the temperature sensing device, obtains the target heating temperature, and controls the heating sheet to stop heating after heating to the target heating temperature, so as to eliminate the fogged surface.

[0096] S230. When the controller detects that the temperature of the mirror surface is lower than the target heating temperature, it sends a heating signal to heat the mirror surface.

[0097] Among them, when the temperature sensing device senses that the temperature of the mirror surface is lower than the target heating temperature, it feeds back the heating signal to the controller. After receiving the heating instruction, the controller transmits the heating signal to the heating sheet to control the heating sheet to dissipate heat energy, eliminating the fogged surface while saving energy consumption.

[0098] Please combine Figure 12 , Figure 12 which shows the schematic flow chart of the sub-steps in step 110 of the anti-fogging method of the portable anti-fogging makeup mirror provided by the present invention.

[0099] In step S110, while sending a heating signal to control the mirror surface to be heated to the highest preset temperature, the following sub-steps are further included:

[0100] S111. Collect the current temperature of the mirror surface as the initial temperature;

[0101] S112. Calculate the difference between the highest preset temperature and the initial temperature;

[0102] S113. Record the heating time, calculate the heating rate, and update the heating signal according to the heating rate.

[0103] In some embodiments, the temperature sensing device collects the current temperature of the mirror surface and feeds back the temperature to the controller. The controller marks this temperature as the initial temperature of the mirror surface. By calculating the difference between the highest preset temperature and the initial temperature, records the heating time from the initial temperature to the highest temperature, obtains the heating rate, and updates the heating signal according to the heating rate. It can be understood that when the temperature sensing device senses that the mirror surface is heated to the preset highest temperature, the environmental temperature situation of the makeup mirror can be obtained through the heating rate; for example, a slow heating rate indicates a lower ambient temperature, and a fast heating rate indicates a higher ambient temperature. If the heating rate is slow according to the preset heating power, it is equivalent to a slow speed of secondary defogging of the mirror surface. Therefore, the heating power needs to be updated according to the heating rate.

[0104] In some preferred embodiments, the heating signal includes heating power; the heating power is inversely correlated with the heating speed. It can be understood that the slower the heating speed, the greater the required heating power to achieve the effect of rapid defogging.

[0105] Please refer to Figure 13 , Figure 13 which shows a schematic flow diagram of the sub-steps in step 220 of the defogging method of the portable anti-fog makeup mirror provided by the present invention.

[0106] In step S220, a preset compensation temperature is obtained, and a target heating temperature is set by combining the fogging temperature and the preset compensation temperature; it includes the following sub-steps:

[0107] S221. Obtain the value of the preset compensation temperature and the value of the fogging temperature;

[0108] S222. Add the value of the preset compensation temperature and the value of the fogging temperature to obtain the target heating temperature.

[0109] In some embodiments, the controller adds the value of the preset compensation temperature and the value of the fogging temperature to obtain the target heating temperature, and transmits the target heating temperature to the heating sheet to control the heating of the heating sheet, so that the mirror surface temperature is higher than the fogging temperature, thereby achieving the effect of removing the fogged surface. At the same time, it can also effectively ensure that there is enough redundancy to ensure that the mirror surface does not fog up when the environment changes.

[0110] In some preferred embodiments, the preset compensation temperature is any value between 2°C and 4°C. It can remove the fogged surface while saving energy consumption and improving the anti-fog reliability of the portable makeup mirror.

[0111] In some preferred embodiments, the preset compensation temperature is inversely correlated with the heating speed. It can be understood that the slower the heating speed, the greater the temperature difference, so the value of the preset compensation temperature should be higher to achieve the effect of quickly removing the fogged surface; and it avoids the problem of large energy consumption caused by repeated heating.

[0112] Please refer to Figure 14 , Figure 14 which shows a schematic flow diagram of the sub-steps in step 210 of the defogging method of the portable anti-fog makeup mirror provided by the present invention.

[0113] In step S210, the fogging condition of the mirror surface is detected, and after receiving the mirror surface fogging signal, the current mirror surface temperature is recorded as the fogging temperature; it includes the following sub-steps:

[0114] S211. Detect whether a defogging start instruction is received;

[0115] S212. If a defogging start instruction is received, record the current mirror surface temperature and set this temperature as the fogging temperature.

[0116] In some embodiments, the mirror fogging signal is a defogging start instruction. The controller detects whether it has received the defogging start instruction. If it has received the defogging start instruction, the current mirror temperature obtained by the temperature sensor is set as the fogging temperature. It can be understood that after the heating sheet heats up to the highest temperature and stops heating, affected by the ambient temperature, the mirror surface will gradually cool down, and due to the temperature difference effect, the mirror surface will fog up again. At this time, the temperature sensing device obtains this fogging temperature and feeds it back to the controller. The controller combines the preset compensation temperature and the fogging temperature and sets it as the target heating temperature, so that the mirror surface temperature is higher than the fogging temperature, achieving the effect of removing the fog on the mirror surface. In this way, when reheating, the heating sheet does not need to heat up to the highest preset temperature to eliminate the fog on the mirror surface, which is beneficial to saving energy consumption, and there is no need to set up a complex circuit system and sensing system, and the circuit is simple; it can obtain the actual fogging temperature according to the surrounding ambient temperature, so that the system can save energy consumption more effectively.

[0117] In some preferred embodiments, in step S211, during the process of detecting whether the defogging start instruction is received, it further includes:

[0118] Continuously monitor the mirror surface temperature at preset intervals;

[0119] If the mirror surface temperature is less than the initial temperature, or the continuous monitoring time exceeds the preset shutdown time, enter the sleep state, stop obtaining the mirror surface temperature and stop sending out the heating signal.

[0120] In this embodiment, the controller continuously monitors the mirror surface temperature at preset intervals. When it monitors that the mirror surface temperature value is less than the initial temperature value, or the continuous monitoring time exceeds the preset shutdown time, the controller and the temperature sensing device will enter the sleep state, stop obtaining the mirror surface temperature and stop sending out the heating signal. To reduce the energy consumption during standby.

[0121] The portable anti-fog makeup mirror of the present utility model is provided with a temperature sensing device and a heating module inside the mirror frame. The temperature sensing device can obtain the temperature of the makeup mirror and feed the temperature back to the controller, thereby controlling the heating sheet to dissipate heat energy to remove the fog on the mirror surface. When the temperature of the makeup mirror reaches the preset highest temperature, the heating sheet stops heating. While removing the fog, it avoids the problem of scalding the user due to too high heating temperature, and also saves energy consumption. In this way, it solves the problem that a portable mirror cannot automatically sense the temperature and adjust the heating temperature according to the actual situation.
