[0010] In an alternative embodiment, obtaining the gravity value collected by the gravity acquisition device includes: when the skin care mode selected by the user is the essence skin care mode, obtaining the gravity value collected by the gravity acquisition device.

[0011] The present invention only performs the subsequent essence export control method when the skin care mode is the essence skin care mode, without dealing with matters related to gravity value and essence export in other irrelevant modes, simplifying the device operation process and the user's understanding cost, enabling the user to focus more on the care process and enhancing the fluency and comfort of the use experience.

[0012] In an alternative embodiment, when controlling the refrigeration device to refrigerate, start timing, and the method further includes: determining whether the current duration reaches a preset duration; when the current duration reaches the preset duration, controlling the refrigeration device to heat, so that the shape memory alloy returns to the initial filling state after sensing the heating temperature.

[0013] The present invention can automatically control the skin care device to stop running and control the refrigeration device to heat after detecting that the skin care duration reaches the preset duration, ensuring that the skin is cared for within a safe range, being able to ensure that each care can achieve the expected effect, and making the skin care effect more stable and reliable.

[0014] In an alternative embodiment, the skin care device further includes a gravity acquisition device for obtaining the gravity value of the essence storage chamber, and the method further includes: if the current duration has not reached the preset duration, but it is detected that the gravity value collected by the current gravity acquisition device is less than the preset gravity threshold, an information for adding essence is output to the user, where the gravity threshold is greater than the initial gravity value, and the initial gravity value represents the gravity value when there is no essence in the essence storage chamber.

[0015] In a second aspect, the present invention provides an essence export control device applied to a skin care device. The skin care device at least includes an essence storage chamber, an electrode head, and a temperature acquisition device. Among them, a refrigeration device is installed inside the electrode head, a circular area is provided outside the electrode head, and a shape memory alloy is filled between the electrode head and the circular area. The device includes: a temperature acquisition module for obtaining the temperature value collected by the temperature acquisition device and detecting whether the difference between the currently collected temperature value and the previously collected temperature value is greater than a preset difference threshold, where the preset difference threshold characterizes the temperature change after the electrode head fits the skin; an essence export module for, if the difference between the currently collected temperature value and the previously collected temperature value is greater than the preset difference threshold, controlling the refrigeration device to refrigerate, so that the shape memory alloy shrinks after sensing the temperature refrigeration, and the essence in the essence storage chamber is exported from the gap between the shrunk shape memory alloy and the circular area.

[0016] In a third aspect, the present invention provides a skin care device. The skin care device at least includes an essence storage chamber, an electrode head, a temperature acquisition device, and a controller.

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] According to an embodiment of the present invention, an embodiment of a essence liquid export control method 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 a different order than here.

[0035] In this embodiment, a essence liquid export control method is provided, which is applied to a skin care device. The skin care device at least includes a essence liquid storage chamber, an electrode head and a temperature acquisition device. Among them, a refrigeration device is installed inside the electrode head, a ring-shaped area is arranged outside the electrode head, and a shape memory alloy is filled between the electrode head and the ring-shaped area. Among them, the type of the skin care device is not limited, as long as the above devices are installed, such as a massager, a cleansing device, a beauty device, etc. In the embodiment of the present invention, a beauty device is taken as an example. As Figure 1 shown, the essence liquid storage chamber is installed at the back position of the skin care device (beauty device) to facilitate the user to add essence liquid. The front surface of the skin care device is the electrode surface. As Figure 2As shown, a plurality of conductive electrode heads are arranged on the electrode surface of the skin care device. An annular area is provided outside each electrode head. Here, the shape of the annular area is not limited and can be a shape matching the electrode head. For example, if the electrode head is circular, the corresponding annular area can be set as a ring. The annular area can also be an independent shape, which can be set by the user according to the actual application effect or design requirements. This is only an example. A shape memory alloy is filled between the electrode head and the annular area. The memory alloy is a type of metal material with special properties and can undergo reversible shape changes within a specific temperature range. When the memory alloy is at a low temperature, the material is in the martensite phase. In this state, the memory alloy is relatively soft and easy to deform. When the memory alloy is heated to a certain temperature or above, the material transforms from the martensite phase to the austenite phase. In this state, the memory alloy becomes hard and returns to its original shape in its "memory". The embodiments of the present invention can control the export of the essence through the characteristics of the memory alloy.

[0036] In the embodiments of the present invention, a refrigeration device is provided inside the electrode head to control the temperature inside the electrode head to be cooled or heated, thereby causing the shape memory alloy to deform. Here, the type of the refrigeration device is not limited and can be a thermoelectric cooler, a heat pipe cooler, a compression refrigerator (applied to large skin care devices), etc. A temperature acquisition device is also installed in the beauty instrument device to acquire the temperature in real time, which is convenient for the controller to determine that the electrode head is in close contact with the skin based on the temperature change acquired by the temperature acquisition device, and then control the refrigeration device to cool. The temperature acquisition device is generally installed near the electrode head, as close as possible to the part in contact with the skin. Since there are a plurality of electrode heads arranged on the electrode surface, in order to ensure that the temperature when the electrode head is in close contact with the skin can be accurately acquired, the temperature acquisition device can be installed at the center of the electrode head. Here, the temperature acquisition device can be a temperature sensor or other devices. This is only an example.

[0037] Figure 3 is a flowchart of the essence export control method according to the embodiments of the present invention. As Figure 3 shown, the process includes the following steps:

[0038] Step S301, obtain the temperature value acquired by the temperature acquisition device, and detect whether the difference between the currently acquired temperature value and the previously acquired temperature value is greater than a preset difference threshold.

[0039] Among them, the preset difference threshold represents the temperature change after the electrode head fits the skin.

[0040] The preset difference threshold in the embodiment of the present invention represents the temperature change after the electrode head fits the skin. The setting of the preset difference threshold can be determined according to the type of the temperature acquisition device. For example, when the temperature acquisition device is a contact sensor, it can only collect temperature data when it touches an object. The corresponding difference threshold should be the corresponding temperature change value from no temperature to skin temperature. When the temperature acquisition device is a sensor that can collect both ambient temperature and skin temperature, the corresponding difference threshold should be the corresponding temperature change value from ambient temperature to skin temperature. This is only an example. The temperature value collected by the temperature acquisition device can be obtained in real time, and it is judged whether the difference between the currently collected temperature value and the previously collected temperature value is greater than the preset difference threshold.

[0041] Step S302, if the difference between the currently collected temperature value and the previously collected temperature value is greater than the preset difference threshold, control the refrigeration device to refrigerate, so that the shape memory alloy shrinks after sensing the refrigerated temperature, and the essence in the essence storage chamber is derived from the gap between the shape memory alloy after shrinking and the annular region.

[0042] In the embodiment of the present invention, when it is detected that the difference between the currently collected temperature value and the previously collected temperature value is greater than the preset temperature difference threshold, it is determined that the electrode head has fit the skin, and then the refrigeration device in the electrode head can be controlled to refrigerate. After the shape memory alloy senses the refrigerated temperature change, it shrinks. As Figure 4 shown, after the memory alloy shrinks, there will be a gap between it and the annular region, and the essence in the essence storage chamber can flow out from the gap between the shape memory alloy after shrinking and the annular region.

[0043] The essence export control method provided by the present invention is applied to a skin care device. The skin care device includes an essence storage chamber, an electrode head and a temperature acquisition device. Among them, a refrigeration device is installed in the electrode head, an annular region is arranged outside the electrode head, and a shape memory alloy is filled between the electrode head and the annular region. When it is determined that the electrode head is close to the skin, control the refrigeration device to refrigerate. After the shape memory alloy senses the refrigerated temperature, it shrinks, and the essence in the essence storage chamber can be derived from the gap between the shape memory alloy after shrinking and the annular region, so as to automatically export the essence for the user to use when the skin care device fits the skin, improving the user experience.

[0044] In this embodiment, an essence export control method is provided, which is applied to a skin care device. The skin care device at least includes an essence storage chamber, an electrode head and a temperature acquisition device. Among them, a refrigeration device is installed in the electrode head, an annular region is arranged outside the electrode head, and a shape memory alloy is filled between the electrode head and the annular region. Figure 5 is a flowchart of the essence export control method according to the embodiment of the present invention. As Figure 5 shown, the process includes the following steps:

[0045] Step S501: Obtain the gravity value collected by the gravity acquisition device, and determine whether the gravity value is greater than a preset gravity threshold. If the gravity value is greater than the preset gravity threshold, execute the step of obtaining the temperature value collected by the temperature acquisition device.

[0046] The skin care device is also equipped with a gravity acquisition device for obtaining the gravity value of the essence storage chamber. The gravity threshold is greater than the initial gravity value, and the initial gravity value represents the gravity value when there is no essence in the essence storage chamber.

[0047] The skin care device according to the embodiment of the present invention is also equipped with a gravity acquisition device. The type of the gravity acquisition device is not limited, and it can be a gravity sensor, etc. It can be installed at the bottom of the essence storage chamber to sense the pressure generated by the essence on the bottom of the storage chamber, or installed on the side of the essence storage chamber, and components such as a side pressure sensor or strain gauge are used to sense the weight change of the essence storage chamber. It can also be installed on the top of the essence storage chamber, and it can be connected to the essence storage chamber by hanging or supporting. The gravity acquisition device obtains the weight change of the essence storage chamber by obtaining the downward pulling force. This is only an example and is not limited.

[0048] When there is no essence in the essence storage chamber, the gravity acquisition device can record the gravity value at this time as the initial gravity value. This initial gravity value corresponds to the weight of the storage chamber itself and some possible fixed components. The initial gravity value can be used as the preset gravity threshold, or an additional gravity margin value can be added to avoid interrupting the operation of the device due to the essence amount approaching zero or misjudgment due to various factors during the care process, resulting in the inability to complete the care process smoothly. Therefore, a certain margin can be left to ensure the smooth completion of the care process. The set preset gravity threshold can be greater than the initial gravity value. This is only an example. When it is determined that the gravity value currently collected by the gravity acquisition device is greater than the preset gravity threshold, it means that there is essence stored in the essence storage chamber, and then the subsequent step of obtaining the temperature value collected by the temperature acquisition device can be executed.

[0049] The present invention needs to determine that there is essence stored in the essence storage chamber before executing the step of obtaining the temperature value collected by the temperature acquisition device, so as to avoid the need for the user to add essence again after the care, which affects the user experience, and can ensure the response speed and operation efficiency of the device.

[0050] In an optional implementation manner, if the gravity value is not greater than the preset gravity threshold, output information for prompting the user to add essence.

[0051] In an embodiment of the present invention, if it is determined that the gravity value is not greater than a preset gravity threshold, information for prompting the addition of essence can be output to the user. Herein, there is no limitation on the way of prompting the user. It can be a voice prompt to the user to add the imported essence, or a warning light can be set on the skin care device, and the user can be prompted to import the essence by the flashing of the warning light or other methods, which is only for example.

[0052] When the gravity value of the present invention is not greater than the preset gravity threshold, the user needs to be prompted to add essence to ensure the normal operation of the device.

[0053] In an alternative embodiment, obtaining the gravity value collected by the gravity acquisition device includes: when it is responded that the skin care mode selected by the user is the essence skin care mode, obtaining the gravity value collected by the gravity acquisition device.

[0054] The skin care device designed in the embodiment of the present invention includes multiple care modes, at least including the essence skin care mode, the whitening mode, the cleaning mode, etc. Other care modes except the essence skin care mode do not need to be paired with essence when in use. Therefore, only when the skin care mode selected by the user is the essence skin care mode, can the gravity value collected by the gravity acquisition device be obtained, and the subsequent essence export control method can be executed.

[0055] Only when the skin care mode of the present invention is the essence skin care mode, the subsequent essence export control method is executed. There is no need to process matters related to the gravity value and essence export in other irrelevant modes, which simplifies the device operation process and the user's understanding cost, enables the user to focus more on the care process, and improves the fluency and comfort of the use experience.

[0056] Step S502, obtaining the temperature value collected by the temperature acquisition device, and detecting whether the difference between the currently collected temperature value and the previously collected temperature value is greater than a preset difference threshold. For details, please refer to Figure 3 Step S301 of the embodiment shown, which will not be elaborated here.

[0057] Step S503, if the difference between the currently collected temperature value and the previously collected temperature value is greater than the preset difference threshold, controlling the refrigeration device to refrigerate, so that the shape memory alloy shrinks after sensing the temperature refrigeration, and the essence in the essence storage chamber is exported from the gap between the shape memory alloy and the annular region after contraction. For details, please refer to Figure 3 Step S302 of the embodiment shown, which will not be elaborated here.

[0058] In this embodiment, an essence export control method is provided, which is applied to a skin care device. The skin care device at least includes an essence storage chamber, an electrode head, and a temperature acquisition device. Among them, a refrigeration device is installed inside the electrode head, an annular region is arranged outside the electrode head, and a shape memory alloy is filled between the electrode head and the annular region.Figure 6 is a flowchart of the essence extraction control method according to an embodiment of the present invention. As Figure 6 shown, the process includes the following steps:

[0059] Step S601: Obtain the temperature value collected by the temperature acquisition device, and detect whether the difference between the currently collected temperature value and the previously collected temperature value is greater than a preset difference threshold. The preset difference threshold characterizes the temperature change after the electrode head fits the skin. For details, please refer to Figure 5 step S502 of the embodiment shown here, which will not be elaborated further.

[0060] Step S602: If the difference between the currently collected temperature value and the previously collected temperature value is greater than the preset difference threshold, control the refrigeration device to refrigerate, so that the shape memory alloy shrinks after sensing the refrigerated temperature, and the essence in the essence storage chamber is exported from the gap between the shrunk shape memory alloy and the annular region. For details, please refer to Figure 5 step S503 of the embodiment shown here, which will not be elaborated further.

[0061] Specifically, when controlling the refrigeration device to refrigerate, start timing. Step S603: Judge whether the current duration reaches the preset duration; when the current duration reaches the preset duration, control the refrigeration device to heat, so that the shape memory alloy returns to the initial filling state after sensing the heating temperature.

[0062] Since there are requirements for the residence time of the skin care device on each piece of skin (too long time may cause damage to the skin, and too short time may lead to poor skin care effect), different care durations are preset for different care modes; in the embodiment of the present invention, when controlling the refrigeration device to refrigerate, or when the user confirms to use the essence skin care mode, timing can start. During the skin care process, when it is judged that the current timing duration reaches the care duration corresponding to the essence skin care mode, regardless of whether there is still essence left in the essence storage chamber, the skin care device should stop running. At this time, a reverse current can be provided to the refrigeration device (such as a thermoelectric cooler) to control its heating, and the shape memory alloy returns to the tightly filled state after sensing the heating temperature.

[0063] After the present invention detects that the skin care duration reaches the preset duration, it can automatically control the skin care device to stop running and control the refrigeration device to heat, ensuring that the skin is cared for within a safe range, and can ensure that each care can achieve the expected effect, making the skin care effect more stable and reliable.

[0064] In an alternative embodiment, the skin care device further includes a gravity acquisition device for obtaining the gravity value of the essence storage chamber. If the current duration has not reached the preset duration, but it is detected that the gravity value collected by the current gravity acquisition device is less than the preset gravity threshold, information for adding essence is output to the user. The gravity threshold is greater than the initial gravity value, and the initial gravity value represents the gravity value when there is no essence in the essence storage chamber.

[0065] In the embodiment of the present invention, when the current duration has not reached the preset duration, that is, during the normal skin care process of the skin care device, the gravity value of the essence storage chamber collected by the gravity acquisition device is obtained in real time. When it is detected that the gravity value collected by the current gravity acquisition device is less than the preset gravity threshold, the user can be prompted to add the imported essence. After the user adds the essence and the gravity value collected by the gravity acquisition device is not less than the preset gravity threshold, the essence export control method can be continued until the current skin care duration reaches the preset duration.

[0066] In a specific embodiment, as Figure 7 shown, taking a beauty device as an example of the skin care device, before using the beauty device for skin care, the user sets whether to add essence, that is, whether to use the essence skin care mode. The user can add essence to the essence storage chamber at the back of the beauty device head. The essence storage chamber can verify whether essence is added through a gravity sensor. If it is continuously detected that no essence is added (that is, the gravity value collected by the gravity sensor is less than the preset gravity threshold), the user can be reminded to add essence by voice; if it is detected that the essence addition is completed, when the user uses the beauty device, the temperature acquisition device (such as a contact temperature sensor) at the center of the beauty device head fits the skin and detects a temperature change, indicating that the electrode head fits the skin, then the semiconductor refrigeration sheet in the electrode head can be controlled to refrigerate. The shape memory alloy senses this refrigeration temperature change, and the memory alloy deforms and shrinks, and the essence oozes out from the gap between the memory alloy after shrinking and the annular area; since there are requirements for the residence time of the beauty device on each piece of skin (too long may cause damage to the skin, too short may result in poor skin care effect), it is judged whether the time is reached according to the residence time set in the mode in a loop. If it is detected that the essence is used up before the time is reached, the user is reminded to add essence. When the time is reached (regardless of whether the essence still exists), a reverse current is provided to the semiconductor refrigeration sheet to control its heating, so that the memory alloy quickly returns to the tightly filled state. For detailed description, please refer to the above embodiments and will not be elaborated here.

[0067] In this embodiment, a skin care device is further provided. The skin care device at least includes a essence storage chamber, an electrode head, a temperature acquisition device, and a controller. Among them, a refrigeration device is installed inside the electrode head, an annular area is provided outside the electrode head, and a shape memory alloy is filled between the electrode head and the annular area. The controller includes: a memory and a processor, which are communicatively connected to each other. Computer instructions are stored in the memory, and the processor executes the computer instructions to execute the above-mentioned essence export control method.

[0068] Specifically, the temperature acquisition device is a contact temperature sensor, which is used to detect the temperature change from no temperature to skin temperature after the electrode head contacts the skin.

[0069] Specifically, the skin care device further includes a gravity acquisition device.

[0070] Specifically, the skin care device is a beauty instrument.

[0071] Specifically, the beauty instrument includes at least one component of a beauty instrument body, a charging base, and a protective case. In the embodiment of the present invention, it is considered that if the beauty instrument touches an object with a temperature similar to the human skin temperature, it will cause mis-conduction. Therefore, when storing, the beauty instrument can be placed vertically with the charging base, or a protective case can be added to cover the head of the beauty instrument to prevent misoperation.

[0072] In this embodiment, an essence export control device is further provided. The device is used to implement the above-mentioned embodiment and preferred implementation manners, and those that have been described will not be repeated. As used hereinafter, the term "module" can be a combination of software and / or hardware that realizes a predetermined function.

As Figure 8 shown, it includes: a temperature acquisition module 801, which is used to acquire the temperature value collected by the temperature acquisition device and detect whether the difference between the currently collected temperature value and the previously collected temperature value is greater than a preset difference threshold. The preset difference threshold represents the temperature change after the electrode head contacts the skin; an essence export module 802, which is used to control the refrigeration device to refrigerate if the difference between the currently collected temperature value and the previously collected temperature value is greater than the preset difference threshold, so that the shape memory alloy shrinks after sensing the temperature refrigeration, and the essence in the essence storage chamber is exported from the gap between the shape memory alloy after shrinking and the annular area.
