[0001] This application is a continuation of International Application No. PCT / CN2024 / 121891, filed on Sep. 27, 2024, which claims priority to Chinese Patent Application No. 202411283771.6, filed on Sep. 13, 2024, and Chinese Patent Application No. 202422261095.4, filed on Sep. 13, 2024. All of the aforementioned applications are incorporated herein by reference in their entireties.TECHNICAL FIELD

[0002] The present disclosure pertains to the technical field of electronic products, and particularly relates to a high-performance smart hair curler.BACKGROUND

[0003] A hair curler, as the name suggests, is a handheld electronic device for perming hair, with a handle and a heating roller as its main constituent parts. In the design of the hair curler, a circuit panel is used to control the temperature, and the material of the heating roller is generally a tourmaline ceramic panel, which can disperse heat evenly, and perform cyclic heating, thereby improving the protein structure of hair to create curls, and protecting hair quality in the perming process.

[0004] In the Chinese Patent Application No. 202410035266.3 previously applied by the applicant of this patent, the motor arranged therein to drive the curling toggle thereof to rotate is disposed inside the hot air discharge passage thereof; although the motor is located in the hot air discharge passage, it can greatly reduce the volume of the hot air curling device and make the overall structure more compact, while the motor can also better drive the curling toggle to rotate.

[0005] However, for relevant patented products, the inventor of this patent found that they still have certain defects and deficiencies during use.

[0006] Specifically, on the one hand, the motor arranged therein is disposed inside the hot air discharge passage thereof, so that the motor is located in the hot air discharge passage; during use, tests show that every time it is put into use, the motor arranged therein has a temperature of 120° C. or above, even up to 180° C., as transmitted to the surface thereof over the use time; the heat resistance level of motors used for products that fall under the category of hair curlers is relevant to the level of insulating materials used therefor, which is generally level B or below, and the motors have a maximum allowable operating temperature of 130° C.; therefore, when working in a high temperature environment for a long time, the motor thereof is prone to burnout, resulting in short service life and low reliability of the above-mentioned patented products. On the other hand, during use, the generated hot air passes through the hot air discharge passage thereof and then is directly output, without the arrangement of any thermal energy storage components; as a result, the heat loss rate is very high, and the hot-roll styling effect on the hair of a user is poor; moreover, the output hot air has a very high temperature, and comes into direct contact with the curling head housing thereof after passing through the curling toggle, so that the curling head housing thereof has a high surface temperature, posing a risk of scalding the user's head; furthermore, the output hot air basically acts on one side of the hair alone, which side fits to the surface of the hot air discharge passage, when the hair is rolled; for the user's hair distal from the surface of the hot air discharge passage after the hair is rolled therein, there is no relatively favorable hot-roll styling effect.

[0007] In view of this, the inventor of this patent, based on his or her work experience, deeply considers the problems encountered in his or her work, browses through a large amount of scientific research materials and literature, searches for new information, and gradually conceives and designs the present application to solve the relevant technical problems.SUMMARY

[0022] a shaft rod located on a lateral side of the front-end rotating shaft of the drive motor is arranged forward at a front end of the hollow cylindrical heating member; the driving gear is fixedly sleeved around the front-end rotating shaft of the drive motor, and the driven gear is fixedly sleeved around the shaft rod, engages with the driving gear, and partially passes through the through-hole to engage with the internal rotating teeth.

[0023] According to one embodiment of the present disclosure, the hair curler further comprises a stop sleeve that is used for blocking hair from entering the hollow connecting base and fixedly sleeved at the rear end of the heating passage;

[0024] the stop sleeve is fixed sleeved around the connecting sleeve, and one coil of stop outer edge is arranged to protrude outward an outer wall at a front end of the stop sleeve.

[0025] According to one embodiment of the present disclosure, multiple air guide ports A that run through an inner wall and an outer wall of the connecting sleeve are evenly opened at a front portion and a middle portion of the connecting sleeve; multiple air guide ports B that run through an inner wall and an outer wall of the stop sleeve are evenly opened at a front portion and a middle portion of the stop sleeve; the multiple air guide ports B correspond one by one to the multiple air guide ports A.

[0029] the multiple coils of heating wires are partially corresponding to and fixedly clamped into the multiple clamping slots located at the same front and rear positions; multiple air guide holes that run through two end faces of the multiple fixing plates are evenly opened on the multiple fixing plates, respectively; multiple air guide sheets are evenly and obliquely opened at a rear end of the outer wall of the inner sleeve, and correspondingly located between rear ends of the multiple fixing plates.

[0030] The present disclosure has the following beneficial effects.

[0031] First of all, in the specific implementation of the high-performance smart hair curler provided by the present application, different from the patented products in the background art, the drive motor is shifted into the hollow cylindrical heating member in the present application, and does not occupy external space. As a result, the present application can still maintain a relatively small volume, and the overall structure is still relatively compact and exquisite, making it convenient to use. Moreover, different from the patented product in the background art, the drive motor is shifted into the hollow cylindrical heating member in the present application, thus it will not be located in the heating passage. In the using process of the present application, the circumstance is similar to the principle of combustion of flames, i.e., the temperature at the root of the flames is often lower than that at the top thereof. Correspondingly, in the present application, as the blowing component blows air toward the hollow cylindrical heating member, after the hollow cylindrical heating member generates heat, the thermal energy thereof can be absorbed by the blown airflow and blown toward the heating passage at once, so that the temperature on the surface of the heating passage will be higher than that inside the hollow cylindrical heating member. As a consequence, the drive motor can operate in a relatively low temperature environment, and is not prone to burnout, thereby possessing a long service life and high reliability.

[0032] Secondly, after the hollow cylindrical heating member generates heat, the thermal energy thereof is absorbed by the blown airflow and blown toward the heating passage at once. The heating passage has a relatively high surface temperature for hot-roll styling of the user's hair. In this process, a relatively large amount of heat is first absorbed and stored by the heat storage core, and then slowly conducted to the heating passage. As a result, when the hot air is discharged through the air outlet holes on the heating passage as arranged, it takes away a little heat. Accordingly, in the using process of the present application, the heat loss rate is low, and the hot-roll styling effect on the user's hair is favorable. Even if the present application is shut down, a relatively large amount of waste heat is still left for hot-roll styling of the user's hair. Thus, the present application has high utilization efficiency.

[0033] Thirdly, the circumstance is similar to the principle of combustion of flames, i.e., the temperature at the root of the flames is often lower than that at the top thereof. Correspondingly, in the present application, the temperature at the rear portion of the heating passage is higher than that at the front end and the middle portion thereof. As such, multiple corresponding air outlet holes that run through the heating passage to the inner wall thereof to be in communication with the hot air introducing channel are evenly opened on the outer wall of the heating passage merely from the front end thereof to the middle portion thereof in the present application. In other words, the air outlet holes are not opened at the rear portion of the outer wall of the heating passage. As a result, it is not easy to directly blow high-temperature hot air to the user's hair at the rear portion of the heating passage. Even if the user's hair is rolled therein at this position, the user's hair will not be easily burned by the high-temperature hot air.

[0034] Fourthly, by arranging the curling housing, a relatively good isolating effect can be achieved to, wherever possible, prevent the user's scalp from direct contact with the heating passage and resultant burns. In other words, by arranging the curling housing, the safety in use of the present application is enhanced. Moreover, the present application uses the hair selector sleeve in place of the traditional curling toggle. The hair selector sleeve in the present application has the same function as the traditional curling toggle, so that while realizing hot-roll styling by rotating around the heating passage in the circumferential direction to roll the user's hair onto the surface of the heating passage, the hair selector sleeve in the present application can also play a relatively good role of isolation, thereby stopping the hot air that is discharged from the air outlet holes opened on the heating passage from being blown to the internal surface of the curling housing, wherever possible. As a result, during use, the curling housing in the present application will not have a very high surface temperature. Compared with the prior art, the present application is safer in use. Even if the curling housing in the present application comes into contact with the user's scalp, the user's scalp is not prone to burns. Therefore, it is safer and more reliable to utilize the present application.

[0035] Fifthly, by arranging the stop outer edge, the user's hair can be stopped and limited in a relatively favorable manner. As a result, the user's hair is not easily rolled into the hollow connecting base, i.e., it is not easily rolled into the position where the rear portion of the heating passage is. Thus, even if the heating passage has a relatively high temperature at the position where the rear portion of the heating passage is, it is more difficult for the user's hair to get burned by the high-temperature hot air at this position since the user's hair is not apt to reach there.

[0036] Sixthly, in the practical use of the present application, a part of the hot air will be blown forward through the air guide gap into the heating passage and discharged through the multiple air outlet holes, so as to act in a relatively favorable manner on one side of the user's hair, which side fits to the external surface of the heating passage, when the hair is rolled. The other part of the air will be guided to exit through the air guide gap, the air guide ports B, and the air guide ports A successively, and discharged from an air exhaust gap between an outer periphery of the stop outer edge and the inner wall of the hollow connecting base, so as to act in a relatively favorable manner on one side of the user's hair, which side is distal from the external surface of the heating passage when the hair is rolled. In this way, the user's hair is heated evenly, the hot-roll styling is uniform, and finally, the hot-roll styling effect can be optimized.

[0037] Some of additional aspects and advantages of the present disclosure will be presented in the following description, and some will become apparent in the following description or be learned through practice of the present disclosure.BRIEF DESCRIPTION OF THE DRAWINGS

[0053] A high-performance smart hair curler 1000 according to embodiments of the present disclosure will be elaborated below with reference to the drawings.

[0054] With reference to FIGS. 1 to 9, the high-performance smart hair curler 1000 provided according to the embodiments of the present disclosure comprises a curling assembly 10, a heating passage 20, a handle 30, a hollow connecting base 40, a hollow cylindrical heating member 50, a blowing component 60, and a drive motor 70;

[0055] Wherein, as shown in FIGS. 2, 5, 8, and 9, the curling assembly 10 is rotatably sleeved around the heating passage 20, and a curling gap A 80 for rolling hair is present between the curling assembly 10 and the heating passage 20; the hollow connecting base 40 is connected between a front end of the handle 30 and a rear end of the heating passage 20; the hollow cylindrical heating member 50 and the blowing component 60 are arranged successively from front to back inside the handle 30, and an air guide gap 50a is arranged in an anterior-posterior direction on the hollow cylindrical heating member 50;

[0056] the blowing component 60 has an air outlet direction that is arranged forward, so as to directly face the air guide gap 50a; the drive motor 70 is fixedly arranged in the hollow cylindrical heating member 50, and has a front-end rotating shaft that extends forward and is connected to a rear end of the curling assembly 10, so as to drive the curling assembly 10 to rotate around the heating passage 20 in a circumferential direction.

[0057] Based on the above arrangement, it can be clearly stated that the present application is mainly used as the high-performance smart hair curler 1000 in the specific implementation.

[0058] Specifically, in the application process of the present application, after the present application in the above-mentioned structure is assembled, the hollow cylindrical heating member 50, the blowing component 60, and the drive motor 70 are started up; the hollow cylindrical heating member 50 will generate heat and cause high temperature; when the blowing component 60 blows air toward the hollow cylindrical heating member 50, hot air is generated and blown to the surface of the heating passage 20 through the air guide gap 50a, so that the heating passage 20 is heated; when the drive motor 70 drives the curling assembly 10 to rotate around the heating passage 20 in the circumferential direction so as to roll the user's hair onto the surface of the heating passage 20, the present application can be used to achieve the hot-roll styling effect.

[0059] Obviously, regarding the employment of the present application as mentioned above, it will have the following technical effects.

[0060] On the one hand, different from the patented products in the background art, the drive motor 70 is shifted into the hollow cylindrical heating member 50 in the present application, and does not occupy external space. As a result, the present application can still maintain a relatively small volume, and the overall structure is still relatively compact and exquisite, making it convenient to use.

[0061] On the other hand, different from the patented product in the background art, the drive motor 70 is shifted into the hollow cylindrical heating member 50 in the present application, thus it will not be located in the heating passage 20. In the using process of the present application, the circumstance is similar to the principle of combustion of flames, i.e., the temperature at the root of the flames is often lower than that at the top thereof. Correspondingly, in the present application, as the blowing component 60 blows air toward the hollow cylindrical heating member 50, after the hollow cylindrical heating member 50 generates heat, the thermal energy thereof can be absorbed by the blown airflow and blown toward the heating passage 20 at once, so that the temperature on the surface of the heating passage 20 will be higher than that inside the hollow cylindrical heating member 50. As a consequence, the drive motor 70 can operate in a relatively low temperature environment, and is not prone to burnout, thereby possessing a long service life and high reliability.

[0062] Moreover, upon testing, the drive motor 70 is fixedly arranged in the hollow cylindrical heating member 50, and has a surface temperature of around 100° C. during operation, which falls within the safe operating temperature range, and makes it safe and reliable to use. At the same time, upon testing, the heating passage 20 has a surface temperature of around 150° C. during operation; as the surface temperature thereof is relatively high, the user's hair can be subjected to hot-roll styling in a relatively favorable manner.

[0063] Further, by optimizing the design in the above manner, the integrated whole formed by the present application has a good usage effect.

[0064] Further, in the specific implementation, as shown in FIGS. 2, 5, 8, and 9 again, according to one embodiment of the present disclosure, a heat storage core 90 for storing thermal energy is embedded inside the heating passage 20 in the anterior-posterior direction;

[0065] wherein, a hot air introducing channel 901 that runs through the heat storage core 90 to an outer wall thereof is opened inside the heat storage core 90 in the anterior-posterior direction, and has a rear end that is in communication with a front end of the air guide gap 50a; multiple air outlet holes 201 that run through the heating passage 20 to an inner wall thereof to be in communication with the hot air introducing channel 901 are opened on an outer wall of the heating passage 20 evenly from a front end thereof to a middle portion thereof.

[0066] Moreover, the heat storage core 90 is preferably made of an aluminum material or a copper material.

[0067] As such, what can be clearly stated is put as follows.

[0068] On the one hand, after the hollow cylindrical heating member 50 generates heat, the thermal energy thereof is absorbed by the blown airflow and blown toward the heating passage 20 at once. The heating passage 20 has a relatively high surface temperature for hot-roll styling of the user's hair. In this process, a relatively large amount of heat is first absorbed and stored by the heat storage core 90, and then slowly conducted to the heating passage 20. As a result, when the hot air is discharged through the air outlet holes 201 on the heating passage 20 as arranged, it takes away a little heat. Accordingly, in the using process of the present application, the heat loss rate is low, and the hot-roll styling effect on the user's hair is favorable. Even if the present application is shut down, a relatively large amount of waste heat is still left for hot-roll styling of the user's hair. Thus, the present application has high utilization efficiency.

[0069] On the other hand, the circumstance is similar to the principle of combustion of flames, i.e., the temperature at the root of the flames is often lower than that at the top thereof. Correspondingly, in the present application, the temperature at the rear portion of the heating passage 20 is higher than that at the front end and the middle portion thereof. As such, multiple corresponding air outlet holes 201 that run through the heating passage 20 to the inner wall thereof to be in communication with the hot air introducing channel 901 are evenly opened on the outer wall of the heating passage 20 merely from the front end thereof to the middle portion thereof in the present application. In other words, the air outlet holes 201 are not opened at the rear portion of the outer wall of the heating passage 20. As a result, it is not easy to directly blow high-temperature hot air to the user's hair at the rear portion of the heating passage 20. Even if the user's hair is rolled therein at this position, the user's hair will not be easily burned by the high-temperature hot air.

[0070] Further, in the specific implementation, with reference to FIGS. 1, 2, 4, and 5, according to one embodiment of the present disclosure, the present disclosure further comprises a curling housing 100;

[0071] wherein, the curling housing 100 has an outer wall, on which at least one hair inlet 1001 is opened in a lengthwise direction thereof, and a rear end that is in insertion connection outside a front end of the hollow connecting base 40, so as to encapsulate the curling assembly 10 and the heating passage 20, and a curling gap B 110 is present between the curling housing 100 and the curling assembly 10.

[0072] As such, by arranging the curling housing 100, a relatively good isolating effect can be achieved to, wherever possible, prevent the user's scalp from direct contact with the heating passage 20 and resultant burns. In other words, by arranging the curling housing 100, the safety in use of the present application is enhanced.

[0073] In addition, in this technical solution, as shown in FIGS. 2, 3, 5, 8, and 9, according to one embodiment of the present disclosure, the curling assembly 10 comprises a hair selector sleeve 101 that is arranged in the anterior-posterior direction and a sleeve ring 102 that is connected to a rear end of the hair selector sleeve;

[0074] wherein, the hair selector sleeve 101 takes the shape of a hollow cylindrical structure, with a front end, on which a curling entrance 1011 extending to a rear portion and a middle portion thereof is opened backward; a connecting sleeve 401 is arranged forward at a middle portion inside the hollow connecting base 40; the heating passage 20 has a rear end that is fixedly sleeved around a front end of the connecting sleeve 401; the sleeve ring 102 is movably clamped between an inner wall at the front end of the hollow connecting base 40 and an outer wall at a rear end of the connecting sleeve 401, and connected to the drive motor 70, so that the drive motor 70 can drive the hair selector sleeve 101 to rotate around the heating passage 20 in the circumferential direction.

[0075] As such, it can be clearly stated that the present application uses the hair selector sleeve 101 in place of the traditional curling toggle. The hair selector sleeve 101 in the present application has the same function as the traditional curling toggle, so that while realizing hot-roll styling by rotating around the heating passage 20 in the circumferential direction to roll the user's hair onto the surface of the heating passage 20, the hair selector sleeve 101 in the present application can also play a relatively good role of isolation, thereby stopping the hot air that is discharged from the air outlet holes 201 opened on the heating passage 20 from being blown to the internal surface of the curling housing 100, wherever possible. As a result, during use, the curling housing 100 in the present application will not have a very high surface temperature. Compared with the prior art, the present application is safer in use. Even if the curling housing 100 in the present application comes into contact with the user's scalp, the user's scalp is not prone to burns. Therefore, it is safer and more reliable to utilize the present application.

[0076] Further, in the specific implementation, with reference to FIGS. 2, 3, and 5-9, according to one embodiment of the present disclosure, the present disclosure further comprises a drive gear set 120;

[0077] wherein, internal rotating teeth 1021 are arranged to surround an inner wall of the sleeve ring 102; a through-hole 4011 that runs through an inner wall and an outer wall of the connecting sleeve 401 is opened at a rear portion of the connecting sleeve 401; the drive gear set 120 is fixedly arranged on the front-end rotating shaft of the drive motor 70, and passes through the through-hole 4011 to engage with the internal rotating teeth 1021.

[0078] As such, by arranging the drive gear set 120 to drive the rotation, it can be realized that the drive motor 70 drives the sleeve ring 102 to rotate outside the connecting sleeve 401, and finally, it can be realized that the hair selector sleeve 101 is driven to rotate around the heating passage 20 in the circumferential direction, so as to roll the user's hair onto the surface of the heating passage 20 and achieve hot-roll styling.

[0079] Preferably, in the technical solution of the present application, as shown in FIGS. 3 and 5-7, according to one embodiment of the present disclosure, the drive gear set 120 comprises a driving gear 1201 and a driven gear 1202;

[0080] wherein, a shaft rod 50b located on a lateral side of the front-end rotating shaft of the drive motor 70 is arranged forward at a front end of the hollow cylindrical heating member 50; the driving gear 1201 is fixedly sleeved around the front-end rotating shaft of the drive motor 70, and the driven gear 1202 is fixedly sleeved around the shaft rod 50b, engages with the driving gear 1201, and partially passes through the through-hole 4011 to engage with the internal rotating teeth 1021.

[0081] In this way, when the drive motor 70 is in operation, it will drive the driving gear 1201 to rotate; the driving gear 1201 will drive the driven gear 1202 to rotate; the driven gear 1202 will drive the sleeve ring 102 to rotate outside the connecting sleeve 401, thereby finally driving the hair selector sleeve 101 to rotate around the heating passage 20 in the circumferential direction so as to roll the user's hair onto the surface of the heating passage 20 and achieve hot-roll styling.

[0082] Obviously, the drive gear set 120 in the present application does not have a complicated structure, and can play a relatively good role of interlinking rotation at a relatively low cost.

[0083] Again, in this technical solution, with reference to FIGS. 2, 3, 5, 8, and 9, according to one embodiment of the present disclosure, the present disclosure further comprises a stop sleeve 130 that is used for stopping hair from entering the hollow connecting base 40 and fixedly sleeved at the rear end of the heating passage 20;

[0084] wherein, the stop sleeve 130 is fixed sleeved around the connecting sleeve 401, and one coil of stop outer edge 1301 is arranged to protrude outward an outer wall at a front end of the stop sleeve 130.

[0085] As such, by arranging the stop outer edge 1301, the user's hair can be stopped and limited in a relatively favorable manner. As a result, the user's hair is not easily rolled into the hollow connecting base 40, i.e., it is not easily rolled into the position where the rear portion of the heating passage 20 is. Thus, even if the heating passage 20 has a relatively high temperature at the position where the rear portion of the heating passage is, it is more difficult for the user's hair to get burned by the high-temperature hot air at this position since the user's hair is not apt to reach there.

[0086] Further, by optimizing the design in the above manner, the integrated whole formed by the present application can have an effectively improved usage effect.

[0087] Preferably, in this technical solution, according to one embodiment of the present disclosure, multiple air guide ports A 4012 that run through an inner wall and an outer wall of the connecting sleeve 401 are evenly opened at a front portion and a middle portion of the connecting sleeve 401; multiple air guide ports B 1302 that run through an inner wall and an outer wall of the stop sleeve 130 are evenly opened at a front portion and a middle portion of the stop sleeve 130; the multiple air guide ports B 1302 correspond one by one to the multiple air guide ports A 4012; moreover, a certain air exhaust gap is present between the outer periphery of the stop outer edge 1301 and the inner wall of the hollow connecting base 40.

[0088] In this regard, it can be clearly stated that in the practical use of the present application, a part of the hot air will be blown forward through the air guide gap 50a into the heating passage 20 and discharged through the multiple air outlet holes 201, so as to act in a relatively favorable manner on one side of the user's hair, which side fits to the external surface of the heating passage 20, when the hair is rolled; the other part of the air will be guided to exit through the air guide gap 50a, the air guide ports B 1302, and the air guide ports A 4012 successively, and discharged from the air exhaust gap between the outer periphery of the stop outer edge 1301 and the inner wall of the hollow connecting base 40, so as to act in a relatively favorable manner on one side of the user's hair, which side is distal from the external surface of the heating passage 20 when the hair is rolled. In this way, the user's hair is heated evenly, the hot-roll styling is uniform, and finally, the hot-roll styling effect can be optimized.

[0089] Further, by optimizing the design in the above manner, the integrated whole formed by the present application can have a further improved usage effect.

[0090] It needs to be added that, in the specific implementation, with reference to FIGS. 6 and 7, according to one embodiment of the present disclosure, the hollow cylindrical heating member 50 comprises an outer sleeve 501, an inner sleeve 502, multiple coils of heating wires 503 that are evenly and fixedly arranged from front to back between the outer sleeve 501 and the inner sleeve 502, and a heat-insulating sleeve 504 that is sleeved around the outer sleeve 501;

[0091] wherein, the air guide gap 50a is present between the outer sleeve 501 and the inner sleeve 502; the blowing component 60 is fixedly arranged outside a rear end of the heat-insulating sleeve 504; the drive motor 70 is clamped into the inner sleeve 502.

[0092] As such, by arranging the heat-insulating sleeve 504 for isolation and thermal insulation, the high temperature caused by the multiple coils of heating wires 503 is not easily transmitted to the handle 30. As a result, when the user holds the handle 30 to use the present application, the user's hand is not prone to burns. Thus, the overall performance of the safety in use of the present application is optimized.

[0093] Moreover, in the specific implementation, as shown in FIG. 7, according to one embodiment of the present disclosure, multiple fixing plates 5021 are evenly and fixedly arranged at an outer wall of the inner sleeve 502 in the anterior-posterior direction, and multiple clamping slots 50211 are opened evenly from front to back on each of the fixing plates 5021;

[0094] wherein, the multiple coils of heating wires 503 are partially corresponding to and fixedly clamped into the multiple clamping slots 50211 located at the same front and rear positions; multiple air guide holes 50212 that run through two end faces of the multiple fixing plates 5021 are evenly opened on the multiple fixing plates 5021, respectively; multiple air guide sheets 5022 are evenly and obliquely opened at a rear end of the outer wall of the inner sleeve 502, and correspondingly located between rear ends of the multiple fixing plates 5021.

[0095] As such, it can be clearly stated that:

[0096] on the one hand, as the multiple circles of heating wires 503 are partially corresponding to and fixedly clamped into the multiple clamping slots 50211 located at the same front and rear positions, they are not prone to forward and backward displacement and circumferential displacement, resulting in good stability during use.

[0097] on the other hand, when the blowing component 60 blows air toward the hollow cylindrical heating member 50, the blown air can be conducted in the circumferential direction through the multiple air guide sheets 5022 as arranged, and flow around the multiple coils of heating wires 503 through the multiple air guide holes 50212, so that the blown air can spiral around the multiple coils of heating wires 503 and be blown forward, which can effectively carry forward the heat generated by the multiple coils of heating wires 503 in a relatively favorable manner; as a result, the inner sleeve 502 will not have a very high internal temperature; in this way, the heat-insulating sleeve 504 fixedly arranged inside the inner sleeve 502 can indeed stay in a relatively low temperature working environment, and is not easily burned out by high temperature.

[0098] Further, it needs to be added that in the specific implementation, according to the high-performance smart hair curler 1000 provided in the embodiments of the present disclosure, the blowing component 60 is a fan, which has an air outlet direction that is arranged forward, the energy storage core is connected to the front end of the connecting sleeve 401 through a fastener such as a fastening bolt, and the blowing component 60 is fixedly arranged outside the rear end of the heat-insulating sleeve 504 through fastening a fastener such as a fastening bolt; in this way, the stability of the overall connection structure of the present application can be enhanced.

[0099] Other embodiments will not be illustrated with examples herein.

[0100] In summary, in the specific implementation of the high-performance smart hair curler 1000 provided by the present application, different from the patented products in the background art, the drive motor 70 is shifted into the hollow cylindrical heating member 50 in the present application, and does not occupy external space. As a result, the present application can still maintain a relatively small volume, and the overall structure is still relatively compact and exquisite, making it convenient to use. Moreover, different from the patented product in the background art, the drive motor 70 is shifted into the hollow cylindrical heating member 50 in the present application, thus it will not be located in the heating passage 20. In the using process of the present application, the circumstance is similar to the principle of combustion of flames, i.e., the temperature at the root of the flames is often lower than that at the top thereof. Correspondingly, in the present application, as the blowing component 60 blows air toward the hollow cylindrical heating member 50, after the hollow cylindrical heating member 50 generates heat, the thermal energy thereof can be absorbed by the blown airflow and blown toward the heating passage 20 at once, so that the temperature on the surface of the heating passage 20 will be higher than that inside the hollow cylindrical heating member 50. As a consequence, the drive motor 70 can operate in a relatively low temperature environment, and is not prone to burnout, thereby possessing a long service life and high reliability.

[0101] In addition, after the hollow cylindrical heating member 50 generates heat, the thermal energy thereof is absorbed by the blown airflow and blown toward the heating passage 20 at once. The heating passage 20 has a relatively high surface temperature for hot-roll styling of the user's hair. In this process, a relatively large amount of heat is first absorbed and stored by the heat storage core 90, and then slowly conducted to the heating passage 20. As a result, when the hot air is discharged through the air outlet holes on the heating passage 20 as arranged, it takes away a little heat. Accordingly, in the using process of the present application, the heat loss rate is low, and the hot-roll styling effect on the user's hair is favorable. Even if the present application is shut down, a relatively large amount of waste heat is still left for hot-roll styling of the user's hair. Thus, the present application has high utilization efficiency.

[0102] Moreover, the circumstance is similar to the principle of combustion of flames, i.e., the temperature at the root of the flames is often lower than that at the top thereof. Correspondingly, in the present application, the temperature at the rear portion of the heating passage 20 is higher than that at the front end and the middle portion thereof. As such, multiple corresponding air outlet holes that run through the heating passage 20 to the inner wall thereof to be in communication with the hot air introducing channel are evenly opened on the outer wall of the heating passage 20 merely from the front end thereof to the middle portion thereof in the present application. In other words, the air outlet holes 201 are not opened at the rear portion of the outer wall of the heating passage 20. As a result, it is not easy to directly blow high-temperature hot air to the user's hair at the rear portion of the heating passage 20. Even if the user's hair is rolled therein at this position, the user's hair will not be easily burned by the high-temperature hot air.

[0103] Furthermore, by arranging the curling housing 100, a relatively good isolating effect can be achieved to, wherever possible, prevent the user's scalp from direct contact with the heating passage 20 and resultant burns. In other words, by arranging the curling housing 100, the safety in use of the present application is enhanced. Moreover, the present application uses the hair selector sleeve 101 in place of the traditional curling toggle. The hair selector sleeve 101 in the present application has the same function as the traditional curling toggle, so that while realizing hot-roll styling by rotating around the heating passage 20 in the circumferential direction to roll the user's hair onto the surface of the heating passage 20, the hair selector sleeve 101 in the present application can also play a relatively good role of isolation, thereby stopping the hot air that is discharged from the air outlet holes 201 opened on the heating passage 20 from being blown to the internal surface of the curling housing 100, wherever possible. As a result, during use, the curling housing 100 in the present application will not have a very high surface temperature. Compared with the prior art, the present application is safer in use. Even if the curling housing 100 in the present application comes into contact with the user's scalp, the user's scalp is not prone to burns. Therefore, it is safer and more reliable to utilize the present application.

[0104] Meanwhile, by arranging the stop outer edge 1301, the user's hair can be stopped and limited in a relatively favorable manner. As a result, the user's hair is not easily rolled into the hollow connecting base 40, i.e., it is not easily rolled into the position where the rear portion of the heating passage 20 is. Thus, even if the heating passage 20 has a relatively high temperature at the position where the rear portion of the heating passage is, it is more difficult for the user's hair to get burned by the high-temperature hot air at this position since the user's hair is not apt to reach there.

[0105] Additionally, in the practical use of the present application, a part of the hot air will be blown forward through the air guide gap 50a into the heating passage 20 and discharged through the multiple air outlet holes 201, so as to act in a relatively favorable manner on one side of the user's hair, which side fits to the external surface of the heating passage 20, when the hair is rolled. The other part of the air will be guided to exit through the air guide gap 50a, the air guide ports B 1302, and the air guide ports A 4012 successively, and discharged from an air exhaust gap between an outer periphery of the stop outer edge 1301 and the inner wall of the hollow connecting base 40, so as to act in a relatively favorable manner on one side of the user's hair, which side is distal from the external surface of the heating passage 20 when the hair is rolled. In this way, the user's hair is heated evenly, the hot-roll styling is uniform, and finally, the hot-roll styling effect can be optimized.

[0106] Further, the high-performance smart hair curler 1000 provided in the present application is indeed extremely practical, and has excellent usage effects. As various technical effects generated during use are stacked together, interrelated, and integrated, the overall performance in use will be very superior. As a result, the present application will inevitably have quite good market promotion value, will necessarily be very popular, and can be effectively popularized.
