Description

Technical Field

[0001] This application relates to the field of beauty product technology, and in particular to a facial mask heating device and a beauty refrigerator. Background Technology

[0002] A beauty refrigerator is a low-temperature storage device used to store skincare products, cosmetics, or nutritional supplements. Face masks, a common type of beauty product, are stored at a low temperature (e.g., 4℃-10℃) in a beauty refrigerator. Applying a chilled face mask directly to the face is not a comfortable experience; it needs to be heated before use to improve comfort.

[0003] Existing facial mask heating devices typically involve inserting the mask into a heating tank for heating. However, if the heating tank is too thick, the heating effect on the mask is poor, resulting in a longer heating time. If the heating tank is too thin, the mask, being relatively soft, is difficult to insert and heat. Utility Model Content

[0004] This application provides a facial mask heating device and a beauty refrigerator to solve the problem that the heating tank of the facial mask heating device cannot simultaneously achieve rapid heating and easy insertion.

[0005] On one hand, some embodiments of this application provide a facial mask heating device, including a first plate, a second plate, a heating element, and at least one actuating element. The second plate is disposed opposite to the first plate and forms a heating groove between them, the heating groove being used to accommodate a facial mask. The heating element is installed on the side of the first plate away from the second plate and is used to heat the first plate. The actuating element is located within the heating groove and is at least installed on one side of the second plate; the actuating element located on the second plate is energized and extends toward the first plate.

[0006] Optionally, the actuating element includes a conductive substrate and a composite metal sheet. The composite metal sheet includes a first metal sheet and a second metal sheet bonded together, the composite metal sheet being connected to the conductive substrate, and at least one end of the composite metal sheet along its length being a free end. The first metal sheet is located inside the second metal sheet facing the conductive substrate, and the coefficient of thermal expansion of the first metal sheet is greater than that of the second metal sheet. When the conductive substrate is energized, the free end of the composite metal sheet moves away from the conductive substrate.

[0007] Optionally, there are multiple actuators. In the heating tank, at least some actuators are connected to the second plate and are spaced apart on the side of the second plate facing the first plate.

[0008] Optionally, the first plate has a clearance notch, and some actuators are located on the side of the first plate away from the second plate and aligned with the clearance notch, for powering on and extending toward the second plate.

[0009] Optionally, the mask heating device further includes a second temperature sensor, which is located inside the heating tank and disposed on the side of the second plate facing the first plate. The second temperature sensor is disposed corresponding to the clearance notch and is used to detect the ambient temperature and the temperature of the mask.

[0010] Optionally, the mask heating device includes a position sensor and a control circuit. The position sensor is located inside the heating tank and is used to detect whether the mask is inserted into the heating tank. When the mask is inserted into the heating tank, the position sensor outputs a first-level signal. Otherwise, the position sensor outputs a second-level signal.

[0011] The control circuit is electrically connected to the actuator, heating element, and position sensor. Upon receiving a first-level signal, the control circuit activates the heating element.

[0012] Optionally, the mask heating device further includes a first temperature sensor, installed on the first plate and electrically connected to the control circuit. The first temperature sensor is used to detect the heating temperature of the first plate. When the temperature of the first plate is greater than a threshold temperature, the first temperature sensor outputs a third-level signal. Otherwise, the first temperature sensor outputs a fourth-level signal. After receiving the third-level signal, the control circuit controls the heating element to shut off.

[0013] Optionally, the mask heating device further includes multiple guide ribs. A heating opening is provided on one side of the heating groove along a first direction. The guide ribs are located within the heating groove and connected to the side of the second plate facing the first plate. The multiple guide ribs are spaced apart along a second direction, which is parallel to the second plate and forms an angle with the first direction. The guide ribs extend along the first direction. From the heating opening to the heating groove along the first direction, the thickness of the guide ribs gradually increases, so that the distance between the guide ribs and the first plate gradually decreases.

[0014] Optionally, along the second direction, the actuator installed on one side of the second plate is located between two adjacent guide ribs.

[0015] Optionally, the minimum spacing between the guide rib and the first plate is 9mm-13mm or 13mm-15mm.

[0016] Optionally, the mask heating device also includes a flip cover and an elastic element. The flip cover is disposed at the heating opening and is used to close the heating opening. The elastic element is connected to the flip cover; when the flip cover blocks the heating opening, the elastic element is in a compressed state. When the flip cover rotates to open the heating opening, the elastic element accumulates elastic potential energy.

[0017] On the other hand, some embodiments of this application also provide a beauty refrigerator, including a refrigerator body and the mask heating device mentioned above, wherein the mask heating device is connected to one side of the refrigerator body.

[0018] The technical solutions provided in this application have the following advantages compared with the prior art:

[0019] In this way, by forming a heating groove between the first plate and the second plate, and heating the first plate with a heating element, the first plate can heat the mask in the heating groove to increase the temperature of the mask. This avoids the situation where the user suffers from low temperature stimulation when the mask is applied to the face, resulting in a better user experience.

[0020] During the heating process of the face mask in the heating tank by the face mask heating device, at least one or more actuating elements are provided on one side of the second plate in the heating tank, and the actuating elements are configured to extend toward the first plate when energized. Thus, by energizing the actuating elements, they extend toward the first plate, causing the face mask in the heating tank to move toward the side closer to the first plate. This reduces the distance between the face mask and the first plate, or allows the face mask to partially or completely contact the first plate, thereby increasing the heating speed and efficiency of the heating elements on the face mask through the first plate. This saves heating time and helps reduce the heating power of the heating elements.

[0021] Because the actuator can actively adjust the distance between the mask and the first plate, when setting the heating groove, the thickness spacing and the size of the groove can be appropriately increased so that the mask can be smoothly inserted into the heating groove without affecting the heating speed and heating efficiency of the mask, resulting in a better user experience.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The following provides numerous different embodiments or examples for implementing various structures of this application. To simplify this application, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0049] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0051] Please see Figures 1 to 12 This application provides a facial mask heating device and a beauty refrigerator to solve the problem that the heating slot of the facial mask heating device cannot simultaneously achieve rapid heating and easy insertion.

[0052] like Figure 1 and Figure 2 As shown, the beauty refrigerator includes a refrigerator body 100 and a mask heating device 200. The mask heating device 200 is located on one side of the refrigerator body 100 and is used to heat a mask A inserted into the mask heating device 200.

[0053] For example, the refrigerator body 100 has a door on the front side, allowing users to open or close the interior space of the refrigerator body 100 through the door. Inside the refrigerator body 100, items such as skincare products, cosmetics, or nutritional supplements can be stored to extend the shelf life of the items by using low temperature (and constant humidity).

[0054] The mask heating device 200 can be located on the left, right, or rear side of the refrigerator body 100, so that after the user takes the mask out of the refrigerator body 100, it can be preheated directly by the mask heating device 200. This ensures that the user will not be stimulated by the low temperature of the mask when using it, and has a better user experience.

[0055] like Figure 3 and Figure 4 As shown, the mask heating device 200 includes a first plate 210, a second plate 220, a heating element 230, and at least one actuating element 240. The second plate 220 is disposed opposite to the first plate 210 and forms a heating groove 251 between them, which is used to accommodate the mask A. The heating element 230 is installed on the side of the first plate 210 away from the second plate 220 and is used to heat the first plate 210 so that the mask in the heating groove 251 is uniformly heated by the heated first plate 210. The actuating element 240 is located in the heating groove 251 and is installed at least on one side of the second plate 220. The actuating element 240 located on the second plate 220 is energized and extends toward the first plate 210.

[0056] For example, the heating groove 251 located between the first plate 210 and the second plate 220 is arranged along the first direction Z, that is, the heating groove 251 is provided with a heating opening 252 on one side along the first direction Z, so that the user can insert the mask A into the heating groove 251 for heating through the heating opening 252.

[0057] The first direction Z can be left-right, front-back, or up-down. If the first direction Z is up-down, the heating opening 252 can be located on the upper side of the heating tank 251 so that the user can insert the mask A into the heating tank 251 from top to bottom for heating.

[0058] The heating element 230 can be a heating wire, a heating plate, or a heating strip, and is disposed on the outer side of the first plate 210 away from the second plate 220. Taking the heating element 230 as a heating wire as an example, multiple turns of the heating wire are wound around the outer side of the first plate 210 to improve the uniformity of heating of the first plate 210. Alternatively, the heating element 230 can also be a heating plate, in which case the outer side of the first plate 210 can be mostly or completely covered by the heating plate, resulting in good heating uniformity.

[0059] Thus, by forming a heating groove 251 between the first plate 210 and the second plate 220, and heating the first plate 210 by the heating element 230, the first plate 210 can heat the mask A in the heating groove 251 to increase the temperature of the mask A, thereby avoiding the situation where the user suffers from low temperature stimulation when the mask is applied to the face, and providing a better user experience.

[0060] During the heating of the face mask A in the heating tank 251 by the face mask heating device 200, one or more actuating elements 240 are provided on one side of the second plate 220 within the heating tank 251, and the actuating elements 240 are configured to extend toward the first plate 210 when energized. Thus, by energizing the actuating elements 240, they extend toward the first plate 210, causing the face mask A in the heating tank 251 to move toward the side closer to the first plate 210. This reduces the distance between the face mask A and the first plate 210, or allows the face mask A to partially or completely contact the first plate 210, thereby increasing the heating speed and efficiency of the heating element 230 over the face mask A through the first plate 210. This saves heating time for the face mask A and helps reduce the heating power of the heating element 230.

[0061] Since the action component 240 can actively adjust the distance between the mask A and the first plate 210, when setting the heating groove 251, the thickness spacing and the size of the groove can be appropriately increased so that the mask A can be smoothly inserted into the heating groove 251 without affecting the heating speed and heating efficiency of the mask A, resulting in a better user experience.

[0062] The actuator 240 can be driven by a motor or cylinder to open and extend toward the first plate 210 when energized.

[0063] Alternatively, action 240 can also be configured with other structures. For example... Figure 5 and Figure 6 As shown, the actuator 240 includes a conductive substrate 241 and a composite metal sheet 242. The composite metal sheet 242 includes a first metal sheet 2421 and a second metal sheet 2422 that are bonded together. The composite metal sheet 242 is connected to the conductive substrate 241, and one or both ends of the composite metal sheet 242 are free ends along its length. The first metal sheet 2421 is located inside the second metal sheet 2422 facing the conductive substrate 241, and the coefficient of thermal expansion of the first metal sheet 2421 is greater than that of the second metal sheet 2422. When the conductive substrate 241 is energized, the free ends of the composite metal sheet 242 move away from the conductive substrate 241.

[0064] Thus, when the conductive substrate 241 is energized, the current acting on the conductive substrate 241 and the composite metal sheet 242 heats the first metal sheet 2421 and the second metal sheet 2422, causing them to expand due to heat. Since the coefficient of thermal expansion of the first metal sheet 2421 is greater than that of the second metal sheet 2422, the expansion size of the first metal sheet 2421 located inside the second metal sheet 2422 (i.e., the side facing the conductive substrate 241) is larger, and the expansion size of the second metal sheet 2422 located outside is smaller, so that the free end of the composite metal sheet 242 can move away from the conductive substrate 241.

[0065] In the heating bath 251, taking the actuating element 240 located on the side where the second plate 220 is located as an example, the conductive substrate 241 is connected to the second plate 220, and the composite metal sheet 242 is located on the side of the conductive substrate 241 away from the second plate 220. After the face mask A is inserted into the heating bath 251, the conductive substrate 241 is controlled to conduct electricity, so that the composite metal sheet 242 is heated and its free end moves toward and extends towards the first plate 210. In this way, the free end of the composite metal sheet 242 can push the face mask A closer to or even in contact with the first plate 210, thereby improving the heating speed and heating efficiency of the face mask A by the first plate 210.

[0066] It should be noted that by using the actuator 240 to reduce the distance between the mask A and the first plate 210 during the heating process, and with the power of the heating element 230 remaining unchanged, the heating time of the mask A can be significantly reduced because the mask A can approach or even contact the first plate 210.

[0067] Alternatively, given a fixed heating time, the heating power of the heating element 230 can be significantly reduced, resulting in energy savings and environmental protection.

[0068] For example, such as Figure 5 As shown, one end of the composite metal sheet 242 can be connected to the conductive substrate 241, and the other end of the composite metal sheet 242 is a free end, resulting in a simple structure.

[0069] Or, such as Figure 6 As shown, the middle portion of the composite metal sheet 242 can also be connected to the conductive substrate 241, so that both ends of the composite metal sheet 242 are free ends along its length. When the conductive substrate 241 is energized, both ends of the composite metal sheet 242 move and simultaneously contact and push the mask A closer to the first plate 210. This increases the contact area between the mask A and the first plate 210 and helps reduce the number of actuators 240.

[0070] It should be noted that, Figure 6 When the conductive substrate 241 is energized, the actuator 240 shown has two free ends that extend out, and the actuator 240 is approximately regarded as a K-shaped structure.

[0071] It should be emphasized that both the conductive substrate 241 and the composite metal sheet 242 are sheet-like structures. When the actuator 240 is not heated or energized and is in its initial state, the actuator 240 can have a very small thickness, which can be less than 2 mm or even 1 mm, and will not hinder the insertion process of the mask A.

[0072] For example, the first metal sheet 2421 can be a copper sheet. Correspondingly, the second metal sheet 2422 can be an iron sheet, a steel sheet, or a constantan sheet, etc., and there is no limitation thereto.

[0073] In some embodiments, such as Figure 7 As shown, there are multiple actuators 240 in the heating tank 251 (e.g. Figure 4 As shown, at least some of the actuators 240 are connected to the second plate 220 and are spaced apart on the side of the second plate 220 facing the first plate 210.

[0074] Thus, by setting multiple actuators 240 on one side of the second plate 220, the number of contact points between the actuators 240 and the mask A after being powered on is increased, thereby pushing the mask A toward the first plate 210. The multiple contact points increase the contact area between the mask A and the first plate 210, thereby improving the heating speed and heating efficiency of the mask A.

[0075] In addition, such as Figure 8 As shown, the first plate 210 is provided with a clearance notch 253, and some of the actuators 240 are located on the first plate 210 away from the second plate 220 (e.g., Figure 4 (as shown) on one side and aligned with the clearance notch 253, for power supply and extending toward the second plate 220.

[0076] By providing a clearance notch 253 on the first plate 210, and providing an actuating member 240 corresponding to the clearance notch 253 on the outer side of the first plate 210, the composite metal sheet 242 of the actuating member 240 is located between the conductive substrate 241 and the second plate 220. This allows the free end of the composite metal sheet 242 of the actuating member 240 to extend towards the second plate 220 through the clearance notch 253 after being energized, thereby pushing the mask A away from the first plate 210. This prevents the first plate 210 from overheating the mask A.

[0077] The number of clearance notches 253 can be one or more, as long as they are set to avoid the heating element 230. Correspondingly, the number of actuators 240 located on the outside of the first plate 210 can also be one or more, with each actuator 240 aligned with a clearance notch.

[0078] Based on this, as shown in Figure 7, the mask heating device 200 also includes a second temperature sensor 274, which is located in the heating tank 251 (e.g., Figure 4 (As shown) It is located inside and on the side of the second plate 220 facing the first plate 210. The second temperature sensor 274 is correspondingly set with the clearance notch 253 and is used to detect the ambient temperature and the temperature of the mask A.

[0079] When the actuator 240 located outside the first plate 210 pushes the mask A toward the second plate 220, the free end of the composite metal sheet 242 can push the mask A to the position of contacting the second temperature sensor 274 because the second temperature sensor 274 is correspondingly set with the clearance notch 253 (such as aligned). This allows the second temperature sensor 274 to directly contact the mask A and detect its temperature.

[0080] Furthermore, when the mask heating device 200 has not started heating and the actuator 240 located outside the first plate 210 is not powered, the real-time temperature of the second temperature sensor 274 can be regarded as the ambient temperature.

[0081] It should be noted that by setting the avoidance notch 253, the actuator 240 can be prevented from directly contacting the first plate 210, and the distance between the actuator 240 and the first plate 210 can be increased, thereby preventing the heating temperature of the first plate 210 from affecting the deformation degree of the actuator 240.

[0082] In some embodiments, such as Figure 4 and Figure 7 As shown, the mask heating device 200 also includes multiple guide ribs 261. A heating opening 252 is provided on one side of the heating groove 251 along the first direction Z. The guide ribs 261 are located within the heating groove 251 and connected to the side of the second plate 220 facing the first plate 210 (i.e., the inner side). The multiple guide ribs 261 are spaced apart along the second direction X, which is parallel to the second plate 220 and forms an angle with the first direction Z. If the first direction Z is vertical, the second direction X can be horizontal or vertical. The guide ribs 261 extend along the first direction Z. Along the first direction X from the heating opening 252 to the heating groove 251, the thickness of the guide ribs 261 gradually increases, so that the distance L between the guide ribs 261 and the first plate 210 gradually decreases.

[0083] By setting guide ribs, the heating groove 251 has a larger opening size at the heating opening 252, which facilitates the insertion and alignment of the mask A. As the mask A is gradually inserted into the heating groove 251 along the first direction Z, the thickness of the guide rib 261 gradually increases, so that the distance between the guide rib 261 and the first plate 210 gradually decreases. This allows the mask A to be inserted deeper and closer to the first plate 210, which is beneficial to improving the heating speed and heating efficiency of the mask A.

[0084] In addition, by setting the guide ribs 261, the actuator 240 and the second temperature sensor 274 located on one side of the second plate 220 can be positioned between two adjacent guide ribs 261, which will not obstruct the insertion process of the mask A and facilitate the smooth insertion of the mask A.

[0085] For example, the guide rib 261 and the second plate 220 can be separate structures, fixedly connected by bolts or adhesive. Alternatively, the guide rib 261 and the second plate 220 can be an integrally formed structure to reduce the number of parts and have higher structural strength.

[0086] In some embodiments, such as Figure 4 As shown, the minimum distance L between the guide rib 261 and the first plate 210 is 9mm-13mm or 13mm-15mm. If the minimum distance L between the guide rib 261 and the first plate 210 is less than 9mm, the reserved gap is too small, making it difficult to insert the mask A into the heating groove. If the minimum distance L between the guide rib 261 and the first plate 210 is greater than 15mm, the gap is too large, resulting in a large distance between the inserted mask A and the first plate 210, which is not conducive to heating the mask A. Furthermore, the large distance makes it insufficient for the extension stroke of the subsequent actuator 240 to push the mask A into contact with the first plate 210.

[0087] For example, the minimum distance between the guide rib 261 and the first plate 210 can be set to 13mm. This facilitates the insertion of the mask A and also allows the extension stroke of the subsequent action member 240 to push the mask A into contact with the first plate 210.

[0088] In some embodiments, such as Figure 9 As shown, the mask heating device 200 also includes a flip cover 262 and an elastic member 263. The flip cover 262 is disposed at the heating opening 252 (e.g., Figure 3 As shown, an elastic element 263 is connected to the flip cover 262 to close the heating opening 252. When the flip cover 262 blocks the heating opening 252, the elastic element 263 is in a compressed state. When the flip cover 262 rotates to open the heating opening 252, the elastic element 263 accumulates elastic potential energy.

[0089] For example, the elastic element 263 can be a torsion spring, installed at the pivot of the flip cover 262 and in a compressed state, so that the flip cover 262 can close the heating opening in the initial position, thereby preventing foreign objects or impurities from falling into the heating groove 251 through the insertion opening. When inserting the mask A, the flip cover 262 can be opened by one end of the mask A or other structure to smoothly insert the mask A into the heating groove 251.

[0090] To facilitate detection of whether a face mask A is inserted into the heating tank 251. For example... Figure 3 and Figure 10 As shown, the mask heating device 200 includes a position sensor 271, which is located inside the heating tank 251 and is used to detect whether the mask is inserted into the heating tank 251. Figure 11 When the face mask is inserted into the heating tank 251, the position sensor 271 outputs a first-level signal. Otherwise, the position sensor 271 outputs a second-level signal. Figure 12 As shown, the mask heating device 200 also includes a control circuit 272, which is electrically connected to the actuator 240, the heating element 230, and the position sensor 271. When the control circuit 272 receives a first level signal, it indicates that a mask A is inserted into the heating tank 251. At this time, the control circuit 272 can be used to control the activation of the heating element 230 to heat the mask A in the heating tank 251.

[0091] For example, position sensor 271 can be a sensitive touch switch, causing mask A located in heating tank 251 to contact the touch switch, thereby causing position sensor 271 to output a first level signal. Alternatively, position sensor 271 can also be a photoelectric sensor, which outputs a first level signal when mask A located in heating tank 251 blocks the signal between photoelectric sensors.

[0092] In some embodiments, such as Figure 4 and Figure 12 As shown, the mask heating device 200 also includes a first temperature sensor 273, which is mounted on the first plate 210 and electrically connected to the control circuit 272. The first temperature sensor 273 is used to detect the heating temperature of the first plate 210. When the temperature of the first plate 210 is greater than a threshold temperature, the first temperature sensor 273 outputs a third-level signal. Otherwise, the first temperature sensor 273 outputs a fourth-level signal. After receiving the third-level signal, the control circuit 272 controls the heating element 230 to shut down to avoid burning or overheating the mask A.

[0093] It should be noted that, because the metal actuating element 240 has a low resistance, a protective resistor is connected in series with the actuating element 240 to reduce the current flowing through it, thereby reducing the heating power at the composite metal sheet 242. This ensures that the composite metal sheet 242 can maintain a suitable and stable heating temperature without overheating, thus preventing the overheated composite metal sheet 242 from damaging the mask A or its outer packaging.

[0094] The mask heating device provided in this application embodiment can be applied to a beauty refrigerator or other locations such as a makeup station, and is not limited thereto.

[0095] For example, refer to Figure 12 The control circuit 272 is electrically connected to the first temperature sensor 273 and the second temperature sensor 274. The actuator 240 can be divided into a first actuator 243 and a second actuator 244. The first actuator 243 is disposed on the second plate 220 (e.g., Figure 4 The second action member 244 is the action member 240 located on the outside of the first plate 210.

[0096] The operating logic of the mask heating device 200 is as follows:

[0097] 1. After the mask heating device 200 is activated, the control circuit 272 detects whether the mask A is inserted into the heating slot 251 via the position sensor 271. If the control circuit 272 receives a first level signal, it indicates that the mask A has been inserted. Subsequently, the control circuit 272 controls the second actuator 244 to be energized for a first preset time (e.g., 10 seconds) to make the mask A contact the second temperature sensor 274, which is used to detect the temperature of the mask A. The control circuit 272 obtains the temperature of the mask A through the second temperature sensor 274 and determines whether the first preset temperature has been reached.

[0098] 2. If the temperature of mask A reaches the first preset temperature (e.g., 25℃), the heating process will end and a prompt signal will be issued.

[0099] 3.1 If the temperature of mask A is lower than the second preset temperature (e.g., 16°C), the control circuit 272 controls multiple first actuators 243 to be energized to push mask A toward the first plate 210, and controls the subsequent heating time to be extended by the second preset time (e.g., 2 minutes).

[0100] 3.2 If the temperature of mask A does not reach the first preset temperature, but is higher than the second preset temperature, the control circuit 272 controls multiple first actuators 243 to be energized to push mask A toward the first plate 210.

[0101] 4. The control circuit 272 detects the ambient temperature through the first temperature sensor 273 or the second temperature sensor 274 and determines the range of the ambient temperature.

[0102] If the ambient temperature is less than or equal to the second preset temperature, the control circuit 272 controls the heating element 230 to start for a third preset duration (e.g., 8 minutes). If the temperature of mask A is less than the second preset temperature, the heating time is the sum of the third preset duration and the second preset duration.

[0103] If the ambient temperature is higher than the first preset temperature, the control circuit 272 controls the heating element 230 to start for a fourth preset duration (e.g., 2 minutes). If the temperature of mask A is lower than the second preset temperature, the heating time is the sum of the fourth preset duration and the second preset duration.

[0104] If the ambient temperature is less than or equal to the first preset temperature and greater than the second preset temperature, the control circuit 272 controls the heating element 230 to start for a fifth preset duration (e.g., 4 minutes). If the temperature of mask A is less than the second preset temperature, the heating time is the sum of the fifth preset duration and the second preset duration.

[0105] 5. After the heating time is reached, the control circuit 272 controls the heating element 230 to turn off and controls the second action element 244 to be energized to detect the temperature of the mask A.

[0106] If the temperature of mask A reaches the first preset temperature, the heating process ends and a prompt signal is issued.

[0107] If the temperature of mask A does not reach the first preset temperature, repeat step 3.1 or step 3.2.
