[0050] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.
[0051] The cosmetic instrument products on the market almost all have a heating function due to the need to dilate pores. Studies have shown that when the skin temperature is higher than 43 degrees Celsius, there is a risk of low-temperature scalding. At the same time, experiments have shown that continuous heating can cause the surface temperature of the cosmetic instrument in contact with the skin to exceed 90 degrees Celsius, which can cause serious skin scalding and harm to the user. Therefore, it is necessary to consider eliminating the situation of harm to the user and improving the product reputation.
[0052] Therefore, in order to solve the problem of skin scalding / frostbite caused by over-temperature of the cosmetic device, the embodiments of the present application provide a control method of a cosmetic device to achieve gentle control at a higher / lower temperature, prevent the cosmetic instrument from heating / cooling too fast and temperature fluctuation being too large, and make the user feel more comfortable and have good and effective results.
[0053] According to the embodiments of the present application, a cosmetic device is provided, as shown in Figure 1 The cosmetic device includes a controller, a semiconductor refrigeration sheet and a metal guide head. The controller and the semiconductor refrigeration sheet are located inside the cosmetic device, which is not shown in Figure 1 . The metal guide head directly contacts the skin, and the semiconductor refrigeration sheet heats / cooling the metal guide head, which is transmitted to the skin. Exemplarily, the cosmetic device can be a cosmetic instrument.
[0054] Specifically, the semiconductor refrigeration sheet is controlled to heat / cool by the controller, such as an MCU. Since the metal guide head of the cosmetic device directly contacts the skin, its temperature control is extremely important. If the temperature is too high, it can cause skin scalding. In the national standard GB4706.10-2008, the requirement of "the temperature rise of the part in contact with the skin or hair shall not exceed the temperature rise limit value for normal use of the continuously held handle" is added in the 11.8; and in the national standard GB4706.1-2005, the requirement of the temperature rise of the metal handle not exceeding 35K is added. However, in practice, when the semiconductor refrigeration sheet continuously heats, the temperature of the metal guide head will quickly rise. Experiments have verified that the temperature can reach more than 90 degrees Celsius, which can further cause skin scalding.
[0055] In the embodiment of the present application, the controller is used to control the working process of the semiconductor refrigeration sheet, so as to control the temperature of the metal guide head in direct contact with the skin, to achieve gentle control at a high temperature, prevent rapid temperature rise and large temperature fluctuation, and further avoid scalding the human skin.
[0056] The working principle and specific working process of the controller can be seen from the detailed description of the method embodiment below, which will not be repeated here.
[0057] According to the embodiment of the present application, a control method of a beauty device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from here.
[0058] In the embodiment, a control method of a beauty device is provided, which can be used for a beauty device such as a beauty instrument, etc. Figure 1 as shown in the accompanying drawings, Figure 2 is a flowchart of the control method of the beauty device according to the embodiment of the present application, as shown in the accompanying drawings, the flow includes the following steps: Figure 2
[0059] Step S201, determine the working period of the semiconductor refrigeration sheet and the target temperature range corresponding to the metal guide head.
[0060] Specifically, the working period [a, b] of the semiconductor refrigeration sheet is composed of the on time a and the off time b of the semiconductor refrigeration sheet, and the semiconductor refrigeration sheet will work in cycles according to the working period [a, b], in each working period, the semiconductor refrigeration sheet first works for a period of time according to the on time a, and then stops working for a period of time according to the off time b, and then enters the next working period, which can prevent the temperature of the metal guide head from rising / falling too fast or fluctuating too much.
[0061] It should be noted that the semiconductor refrigeration sheet can be used for heating and cooling, and the working principle of the semiconductor refrigeration sheet is mainly based on the Peltier effect in the thermoelectric effect. When electric current passes through a thermocouple composed of N-type semiconductor material and P-type semiconductor material, heat transfer will occur between the two ends, and heat will be transferred from one end to the other end, so as to generate temperature difference to form cold and hot ends, and realize refrigeration. Conversely, if the direction of the electric current is changed, the direction of the heat transfer will also be changed, so as to realize heating.
[0062] In the embodiment, the working modes of the beauty device include a hot compress mode, a cold compress mode, etc., the metal guide head corresponds to a target temperature range in different modes, and the semiconductor refrigeration sheet corresponds to a working cycle in different modes. For example, when the user starts the hot compress mode, the semiconductor refrigeration sheet is mainly used for heating; and when the user starts the cold compress mode, the semiconductor refrigeration sheet is mainly used for refrigeration. It should be noted that the target temperature range can be set according to the actual application scene and the human body adaptation condition.
[0063] In step S202, the semiconductor refrigeration sheet is controlled to work in the working cycle, and the current temperature of the metal guide head is detected.
[0064] Specifically, the semiconductor refrigeration sheet is controlled to be turned on and turned off according to the currently determined working cycle. During the working of the semiconductor refrigeration sheet, the current temperature of the metal guide head can be detected in real time through a temperature sensing bag, a temperature sensor, etc., and it is determined whether the current temperature is in the target temperature range. If the current temperature is not in the target temperature range, step S203 is performed.
[0065] In step S203, when it is detected that the current temperature is not in the target temperature range, the time proportion of the turn-on time and the turn-off time of the semiconductor refrigeration sheet in the working cycle is adjusted based on the current temperature and the target temperature range, and step S202 is returned.
[0066] Specifically, according to the gap between the current temperature and the target temperature range, a corresponding mode is selected to adjust the time proportion of the turn-on time and the turn-off time of the semiconductor refrigeration sheet in the working cycle, so as to adjust the heating / refrigeration time proportion of the semiconductor refrigeration sheet, maintain the temperature of the metal guide head in the target temperature range, prevent the temperature from changing too fast, thereby avoiding damage to the user's skin and improving the user's body feeling during use.
[0067] The control method of the beauty device provided in the embodiment controls the semiconductor refrigeration sheet of the beauty device to be turned on and turned off in the working cycle, prevents the temperature from continuously rising / falling, detects the current temperature of the metal guide head of the beauty device during the working of the semiconductor refrigeration sheet, and determines whether the current temperature is in the target temperature range of the beauty device. If the current temperature is not in the target temperature range, the time proportion of the turn-on time and the turn-off time of the semiconductor refrigeration sheet in the working cycle is adjusted, the heating / refrigeration time of the semiconductor refrigeration sheet in each working cycle is reasonably controlled, the temperature is prevented from changing too fast, thereby avoiding damage to the user's skin and improving the user's body feeling during use.
[0068] In the embodiment, a control method of a beauty device is provided, which can be used for a beauty device such as a beauty instrument, etc., as shown in Figure 1 When the semiconductor refrigeration sheet is used for heating, Figure 3is a flowchart of a control method of a cosmetic device according to an embodiment of the present application, as shown in the figure, the flow includes the following steps: Figure 3
[0069] Step S301, determine the working period of the semiconductor refrigeration piece and the target temperature range corresponding to the metal guide head. For details, please refer to step S201 of the embodiment shown in Figure 2 , which will not be repeated here.
[0070] Step S302, control the semiconductor refrigeration piece to work in the working period, and detect the current temperature of the metal guide head. For details, please refer to step S202 of the embodiment shown in Figure 2 , which will not be repeated here.
[0071] Step S303, when it is detected that the current temperature is not in the target temperature range, based on the current temperature and the target temperature range, adjust the time proportion of the on time and the off time of the semiconductor refrigeration piece in the working period, and return to step S302.
[0072] Specifically, when the semiconductor refrigeration piece is used for heating, the above step S303 includes:
[0073] Step S3031, obtain a target hot compress temperature according to the lower limit value of the target temperature range, and calculate a first temperature difference reference value based on the difference between the upper limit value and the lower limit value of the target temperature range.
[0074] Specifically, when the semiconductor refrigeration piece is used for heating, the target temperature range corresponding to the metal guide head can be [T R , T R + ΔT R ], the lower limit value of the range is the target hot compress temperature T R , and the difference between the upper limit value and the lower limit value of the range is the first temperature difference reference value ΔT R . Among them, according to the human skin bearing capacity, the target hot compress temperature T R is generally valued in the range of 38-42℃, which can be set according to the actual scene.
[0075] Step S3032, when it is detected that the current temperature is greater than the target hot compress temperature, and the temperature difference between the current temperature and the target hot compress temperature is greater than the first temperature difference reference value, reduce the time proportion of the heating on time of the semiconductor refrigeration piece in the working period, and increase the time proportion of the heating off time of the semiconductor refrigeration piece in the working period, and return to step S302.
[0076] Specifically, if it is detected that the current temperature T>T R , and the temperature difference ΔT1 between the current temperature T and the target hot compress temperature T R is greater than ΔT R If yes, the on-time a of the semiconductor refrigeration piece in the heating period of the working cycle is reduced, and the off-time b of the semiconductor refrigeration piece is increased, the working cycle is updated, and the step S302 is returned, the semiconductor refrigeration piece is controlled to be turned on and turned off according to the adjusted working cycle, and the metal guide head is cooled to control the current temperature in the target temperature range.
[0077] Specifically, if the current temperature T < T R , the semiconductor refrigeration piece is continuously controlled to heat according to the current working cycle, so that the metal guide head reaches the target hot compress temperature T R .
[0078] In the embodiment of the present application, when the semiconductor refrigeration piece is used for heating, if the current temperature of the metal guide head exceeds the target hot compress temperature in the heating period, and the exceeding part is greater than the first temperature difference reference value in the heating period, the on-time of the semiconductor refrigeration piece in the heating period of the working cycle is reduced, and the off-time is increased, the semiconductor refrigeration piece is controlled to be turned on and turned off according to the adjusted working cycle, and the metal guide head is cooled to control the temperature of the metal guide head, prevent the temperature from rising too fast or the temperature fluctuation from being too large, avoid scalding the user's skin, and thus improve the user's experience.
[0079] In step S304, when it is detected that the current temperature is greater than the first temperature threshold, the semiconductor refrigeration piece is controlled to be turned off; wherein the first temperature threshold is greater than the upper limit of the target temperature range.
[0080] Specifically, when it is detected that the current temperature T > the first temperature threshold T1, the semiconductor refrigeration piece is turned off, the heating is stopped, and the off-time t of the semiconductor refrigeration piece is recorded. It should be noted that the first temperature threshold T1 > T R + ΔT R According to the human skin bearing capacity, the first temperature threshold T1 is generally in the range of 43℃-48℃, and the embodiment of the present application is not limited thereto.
[0081] In step S305, when it is detected that the off-time of the semiconductor refrigeration piece reaches the first preset time t1, it is judged whether the current temperature of the metal guide head is less than the target hot compress temperature.
[0082] Specifically, when it is detected that the off-time t of the semiconductor refrigeration piece reaches the first preset time t1, it is judged whether the current temperature of the metal guide head is less than the target hot compress temperature T R If yes, the step S306 is executed; otherwise, the step S307 is executed.
[0083] It should be noted that the first preset time t1 is the minimum restart heating time, which is generally set to 5s-40s, so as to avoid frequently turning on and off the semiconductor refrigeration piece when the temperature fluctuates, and thus cause poor temperature control effect and large temperature fluctuation.
[0084] Step S306, if the current temperature is less than the target hot compress temperature, control the semiconductor refrigeration piece to restart heating.
[0085] Specifically, if the current temperature of the metal guide head decreases to the target hot compress temperature T R The semiconductor refrigeration piece is restarted to heat.
[0086] In the embodiment of the present application, when it is detected that the current temperature of the metal guide head exceeds the set first temperature threshold, the semiconductor refrigeration piece is first controlled to stop heating for a period of time to rapidly cool the metal guide head, so as to avoid causing damage to the user's skin. When the heating stop time reaches the first preset time length, the semiconductor refrigeration piece is restarted to heat, and the heating working process is re-entered, so as to improve the user's feeling.
[0087] Step S307, when it is detected that the current temperature is greater than the second temperature threshold, control the semiconductor refrigeration piece to be turned off and alarm; wherein the second temperature threshold is greater than the first temperature threshold.
[0088] Specifically, no matter what the situation is, as long as it is detected that the current temperature of the metal guide head is greater than the second temperature threshold T2, alarm processing is performed, and the semiconductor refrigeration piece is turned off. It should be noted that the second temperature threshold T2 is greater than the first temperature threshold T1, and according to the human skin bearing capacity, the second temperature threshold T2 is generally valued in the range of 49-60℃, and the embodiment of the present application is not limited thereto.
[0089] In the embodiment of the present application, when the current temperature of the metal guide head exceeds the set second temperature threshold, it indicates that the temperature of the metal guide head is too high, and at this time, alarm processing is directly performed, and the semiconductor refrigeration piece is turned off, so as to avoid scalding the user's skin.
[0090] The control method of the beauty device provided in the embodiment controls the semiconductor refrigeration piece of the beauty device to cycle on and off in a working cycle to prevent the temperature from continuously rising. In the working process of the semiconductor refrigeration piece, the current temperature of the metal guide head of the beauty device is detected, and it is judged whether the current temperature is within the target temperature range. If the current temperature of the metal guide head exceeds the target hot compress temperature, and the exceeding part is greater than the first temperature difference reference value, then the on time of the semiconductor refrigeration piece in the working cycle is reduced and the off time is increased, the heating time of the semiconductor refrigeration piece in each working cycle is reasonably controlled, the temperature is prevented from rising too fast, and thus scalding of the user's skin is avoided, and the user's feeling during use is improved.
[0091] In the embodiment, a control method of a beauty device is provided, which can be used for a beauty device such as a beauty instrument, etc. Figure 1 As shown in the beauty device, such as a beauty instrument, etc., when the semiconductor refrigeration piece is used for refrigeration, Figure 4is a flowchart of a control method of a cosmetic device according to an embodiment of the present application, as shown in the figure, the flow includes the following steps: Figure 4
[0092] Step S401, determine the working period of the semiconductor refrigeration piece and the target temperature range corresponding to the metal guide head. For details, please refer to step S201 of the embodiment shown in Figure 2 , which will not be repeated here.
[0093] Step S402, control the semiconductor refrigeration piece to work in the working period, and detect the current temperature of the metal guide head. For details, please refer to step S202 of the embodiment shown in Figure 2 , which will not be repeated here.
[0094] Step S403, when it is detected that the current temperature is not in the target temperature range, based on the current temperature and the target temperature range, adjust the time proportion of the on time and the off time of the semiconductor refrigeration piece in the working period, and return to step S402.
[0095] Specifically, when the semiconductor refrigeration piece is used for refrigeration, the above step S403 includes:
[0096] Step S4031, obtain a target cooling temperature according to the upper limit value of the target temperature range, and calculate a second temperature difference reference value based on the difference between the upper limit value and the lower limit value of the target temperature range.
[0097] Specifically, when the semiconductor refrigeration piece is used for refrigeration, the target temperature range corresponding to the metal guide head can be [T L -ΔT L , T L ], the upper limit value of the range is the target cooling temperature T L , and the difference between the upper limit value and the lower limit value of the range is the second temperature difference reference value ΔT L . Wherein, the target cooling temperature T L can be set according to the human body bearing capacity and the actual scene.
[0098] Step S4032, when it is detected that the current temperature is less than the target cooling temperature, and the temperature difference between the target cooling temperature and the current temperature is greater than the second temperature difference reference value, reduce the time proportion of the refrigeration on time of the semiconductor refrigeration piece in the working period, and increase the time proportion of the refrigeration off time of the semiconductor refrigeration piece in the working period, and return to step S402.
[0099] Specifically, if it is detected that the current temperature T L and the temperature difference ΔT2 between the target cooling temperature T L and the current temperature T is greater than ΔT L If the on-time 'a' of the thermoelectric cooler during cooling is reduced and the off-time 'b' of the thermoelectric cooler is increased, the working cycle is updated, and the process returns to step S402. The thermoelectric cooler is then controlled to cycle on and off according to the adjusted working cycle, thereby heating the metal conductor and ensuring that the current temperature is within the target temperature range.
[0100] Specifically, if the detected current temperature T>T L Then, the semiconductor cooling chip continues to cool according to the current working cycle, so that the metal guide reaches the target cooling temperature T. L .
[0101] In this embodiment of the invention, when the thermoelectric cooler is used for cooling, if the current temperature of the metal probe is lower than the target cooling temperature and the insufficient part is greater than the second temperature difference reference value during cooling, then the on-time of the thermoelectric cooler during cooling in the working cycle is reduced and the off-time is increased.
