Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, and in particular to a multi-head intelligent hot air straightener. Background Technology

[0002] A hair straightener, as the name suggests, is used to straighten hair by heating and softening it with a heating element.

[0003] Existing hair straighteners generally use heated plates to clamp and straighten hair. They are essentially limited to straightening and lack other functions, such as functioning as a hairdryer, a regular comb, or a heated comb. This makes them impractical. Furthermore, the heating plates typically reach temperatures of over 100 degrees Celsius. The middle layer of hair, which is not in contact with the heating plates, is less likely to soften due to heat, resulting in poor straightening. Hair in prolonged contact with the heating plates is also prone to burns, leading to poor reliability and overall unsatisfactory performance.

[0004] In response, the inventor of this patent, drawing on work experience, deeply considered the problems encountered in his work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems.

[0027] The beneficial effects of this utility model are:

[0028] Firstly, in specific implementation, the multi-head intelligent hot air hair straightener provided in this application optimizes and improves the structure of the upper clamp arm and the lower clamp arm so that they have corresponding upper and lower extension parts, making it convenient to connect the hair care head. When the hair care head is not in use, this application can be used as a hot air hair straightener. When the hair care head is assembled, this application can be used as a hot air hair dryer to blow-dry and care for the user's hair with hot air, making this application multi-functional and flexible in use.

[0029] Secondly, compared to existing traditional hair straighteners, this application features an upper clamping slot and a lower clamping slot to clamp the user's hair. Specifically, an upper partition is installed inside the upper clamping slot along its length, and a lower partition is installed inside the lower clamping slot along its length. An upper exhaust channel is formed between the upper clamping slot and the upper partition, and a lower exhaust channel is formed between the lower clamping slot and the lower partition. A middle exhaust channel and a hair clamping space are formed between the upper partition and the lower partition. This ensures that a certain amount of hot air flow space is formed between the upper clamping slot and the lower clamping slot, allowing the hot air entering the slot to be blown as evenly as possible onto the surface of each strand of the user's hair clamped therein to heat it, resulting in good uniform heating of the user's hair and a good straightening effect.

[0030] Thirdly, when the upper clamping arm and the lower clamping arm are closed to clamp the user's hair, the upper hot air outlet channel is located at the bottom right side of the upper clamping groove, allowing the hot air outlet therein to flow as far to the left as possible along the formed hot air flow space to heat the user's hair. Similarly, the lower hot air outlet channel is located at the bottom right side of the lower clamping groove, allowing the hot air outlet therein to flow as far to the left as possible along the formed hot air flow space to heat the user's hair. In this way, the hot air utilization efficiency of this application is high.

[0031] Fourthly, this application uses hot air to heat and soften the user's hair in order to straighten it. Compared with the traditional method of using a heating plate to clamp the user's hair for heating and softening, this application is safer and less likely to cause high temperature burns to the user's hair or burns to the user's scalp or the operator's hands.

[0032] Fifthly, when using this application to clamp and straighten a user's hair, the supplied hot air is led out through the upper hot air outlet channel to the upper clamping slot and through the lower hot air outlet channel to the lower clamping slot. Most of the hot air ultimately enters the upper and lower clamping slots and is discharged from the upper and lower exhaust channels, respectively, to provide hot air blowing and conditioning to the parts of the user's hair that are not clamped. Compared to existing traditional hair straighteners, this application uses an upper and lower partition to clamp the user's hair, forming an upper exhaust channel between the upper clamping slot and the upper partition, and a lower exhaust channel between the lower clamping slot and the lower partition. This prevents the hot air from being blocked by the user's hair being clamped between the upper and lower partitions, thus ensuring smooth hot air discharge and effectively improving the reliability of the application.

[0033] Sixthly, based on traditional hair straighteners, this application further adds an upper plasma / negative ion generating component, a lower plasma / negative ion generating component, multiple upper plasma / negative ion needles, and multiple lower plasma / negative ion needles. This allows the straightener to generate a large number of plasma / negative ions when powered on. These plasma / negative ions are then blown by hot air and adhere to the user's hair or scalp surface. During use, the generated plasma and negative ions form a film adhering to the user's hair and scalp, providing overall protection and reducing the risk of burns and physical friction damage. It also neutralizes static electricity, making the user's hair less frizzy and flyaway, resulting in smoother and easier-to-manage hair. Furthermore, it increases hair shine, effectively removes odors from the hair and scalp, and has a good antibacterial effect on the hair and scalp, ultimately maintaining the user's hair cleanliness and health.

[0034] Seventhly, in specific implementation, this application can switch between multiple functions, such as being used as a hot air hair straightener, a hair dryer, a hot air comb, a regular comb, and a heated hair straightening comb, making its functions truly comprehensive and its uses wide-ranging, truly achieving multi-purpose functionality and being very flexible and versatile in use.

[0035] Eighthly, the air inlet mesh cover described in this application is attached to the outside of the dust filter by magnetic attraction or snap-fit, which facilitates the quick disassembly of the air inlet mesh cover and allows for regular or irregular cleaning and maintenance of the dust filter.

[0036] Ninthly, after the upper heating wire component and the lower heating wire component are heated, hot air can be emitted and conducted to the surface of the upper heat-conducting aluminum sheet and the lower heat-conducting aluminum sheet. This allows the heat energy to be stabilized better through the upper heat-conducting aluminum sheet and the lower heat-conducting aluminum sheet when the user uses this application to straighten their hair. This results in a better straightening effect on the user's hair. Furthermore, by setting the soft rubber strip, the user's hair can be gripped better and is less likely to slip, which facilitates better hot air straightening of the user's hair. Thus, the overall effect of this application can be optimized.

[0096] The following describes in detail, with reference to the accompanying drawings, an embodiment of the multi-head intelligent hot air hair straightener 1000 of this utility model.

[0097] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 16 As shown, the multi-head intelligent hot air straightener 1000 provided according to the embodiment of the present invention includes an upper clamping arm 10, a lower clamping arm 20, and a hot air generating component 30 for supplying hot air to the interior of the upper clamping arm 10 and the interior of the lower clamping arm 20; the improvement of the present invention is that it also includes a hair care head 40.

[0098] The lower bottom surface of the upper clamping arm 10 is disposed opposite to the upper end surface of the lower clamping arm 20, and the middle part of the lower bottom surface of the upper clamping arm 10 is recessed upward along its length to form an upper clamping groove 101 for clamping hair, and the middle part of the upper end surface of the lower clamping arm 20 is recessed downward along its length to form a lower clamping groove 201 for clamping hair.

[0099] Furthermore, an upper hot air outlet channel 1011 is opened on the right side of the upper clamping groove 101 along the length of its bottom, extending into the interior of the upper clamping arm 10; and a lower hot air outlet channel 2011 is opened on the right side of the lower clamping groove 201 along the length of its bottom, extending into the interior of the lower clamping arm 20.

[0100] Furthermore, the upper clamping arm 10 extends to the left along its length direction to form an upper outward extension 102, and the lower clamping arm 20 extends to the left along its length direction to form a lower outward extension 202. An exhaust gap 50 is formed between the upper outward extension 102 and the lower outward extension 202.

[0101] In this application, the hair care head 40 is detachably sleeved on the upper extension 102 and the lower extension 202 to guide the hot air discharged from the exhaust gap 50 to the hair surface.

[0102] Based on the above, it is clear that this application is mainly used as a multi-head intelligent hot air hair straightener 1000 in specific implementation.

[0103] Specifically, when applying this application, on the one hand, compare with Figure 1 and Figure 2 As shown, when the hair care head 40 is removed, the user's hair is clamped between the upper clamping groove 101 and the lower clamping groove 201. When the hot air generating member 30 supplies hot air to the inside of the upper clamping arm 10 and the inside of the lower clamping arm 20, the supplied hot air can be led out to the upper clamping groove 101 through the upper hot air outlet channel 1011 and to the lower clamping groove 201 through the lower hot air outlet channel 2011. In this way, the user's hair clamped between the upper clamping groove 101 and the lower clamping groove 201 is heated. This process allows the user's hair to slide away from the application along the hair, thus straightening the user's hair with hot air. On the other hand, compared with Figure 7 , Figure 10 , Figure 15 and Figure 16 As shown, when the hair care head 40 is installed, an exhaust gap 50 is formed between the upper extension 102 and the lower extension 202. In this way, when the hair care head 40 is fitted over the upper extension 102 and the lower extension 202, the hot air discharged from the exhaust gap 50 can be guided to the surface of the user's hair to perform hot air blowing care on the user's hair.

[0104] The use of this application as described above will obviously have the following technical effects:

[0105] Firstly, this application optimizes and improves the structure of the upper clamping arm 10 and the lower clamping arm 20 so that they have corresponding upper extension 102 and lower extension 202, making it convenient to connect the hair care head 40. When the hair care head is not in use, this application can be used as a hot air straightener. When the hair care head 40 is assembled, this application can be used as a hot air hair dryer to blow-dry and care for the user's hair with hot air. This makes this application multi-functional and flexible in use.

[0106] Secondly, compared with existing traditional hair straighteners, this application sets up the upper clamping groove 101 and the lower clamping groove 201 to clamp the user's hair. A certain hot air flow space can be formed between the upper clamping groove 101 and the lower clamping groove 201, so that the hot air entering there can be blown as evenly as possible to the surface of each strand of the user's hair clamped there to heat it, so that the user's hair is heated evenly and the straightening effect is good.

[0107] Thirdly, when the upper clamping arm 10 and the lower clamping arm 20 are closed to clamp the user's hair, the upper hot air outlet channel 1011 is located at the bottom right side of the upper clamping groove 101, so that the hot air outlet therein can flow to the left as much as possible along the formed hot air flow space to heat the user's hair. Similarly, the lower hot air outlet channel 2011 is located at the bottom right side of the lower clamping groove 201, so that the hot air outlet therein can also flow to the left as much as possible along the formed hot air flow space to heat the user's hair. In this way, the hot air utilization efficiency of this application is high.

[0108] Fourthly, this application uses hot air to heat and soften the user's hair in order to straighten it. Compared with the traditional method of using a heating plate to clamp the user's hair for heating and softening, this application is safer and less likely to cause high temperature burns to the user's hair or burns to the user's scalp or the operator's hands.

[0109] Furthermore, through the above-mentioned optimized design, the whole constituted by this application has comprehensive functions, strong practicality, and strong reliability, resulting in a good overall use effect.

[0110] Furthermore, in specific implementation, in accordance with... Figure 3 and Figure 4 As shown, the lower bottom surface of the upper extension 102 has multiple upper air vents 1021 opening upward along its length direction, and the upper end surface of the lower extension 202 has multiple lower air vents 2021 opening downward along its length direction.

[0111] Furthermore, an upper partition 180 made of thermally conductive aluminum is installed inside the upper clamping groove 101 along its length, and a lower partition 190 made of thermally conductive aluminum is installed inside the lower clamping groove 201 along its length. An upper exhaust channel is formed between the upper clamping groove 101 and the upper partition 180, a lower exhaust channel is formed between the lower clamping groove 201 and the lower partition 190, and a middle exhaust channel and hair clamping space are formed between the upper partition 180 and the lower partition 190.

[0112] Therefore, compared with existing traditional hair straighteners, this application sets the upper partition 180 and the lower partition 190 to clamp the user's hair. An upper exhaust channel is formed between the upper clamping groove 101 and the upper partition 180, and a lower exhaust channel is formed between the lower clamping groove 201 and the lower partition 190. This allows some hot air to flow through and be discharged from the upper exhaust channel 1021 and the lower exhaust channel 2021, so as to blow-dry and care for the parts of the user's hair that are not clamped. This prevents the hot air from being blocked and difficult to discharge when the user's hair is clamped between the upper partition 180 and the lower partition 190. In this way, the hot air discharge of this application is indeed smooth, and the reliability of use is effectively improved.

[0113] Furthermore, in the specific implementation, we will continue to refer to... Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the surface of the upper clamping groove 1012 is uniformly provided with a plurality of upper clamping holes 103 that penetrate into the upper clamping arm 10 along its length direction; the surface of the lower clamping groove 2012 is uniformly provided with a plurality of lower clamping holes 203 that penetrate into the lower clamping arm 20 along its length direction.

[0114] In this application, the upper clamping arm 10 is provided with an upper plasma / negative ion generating component 60, which has a plurality of upper plasma / negative ion needles 601 extending into the plurality of upper clamping holes 103; the lower clamping arm 20 is provided with a lower plasma / negative ion generating component 70, which has a plurality of lower plasma / negative ion needles 701 extending into the plurality of lower clamping holes 203.

[0115] Therefore, based on the traditional hair straightener, this application further adds the aforementioned upper plasma / negative ion generating component 60, lower plasma / negative ion generating component 70, multiple upper plasma / negative ion needles 601, and multiple lower plasma / negative ion needles 701. This allows it to generate a large number of plasma / negative ions when powered on. The generated plasma / negative ions are then blown by hot air and adhere to the user's hair or scalp surface. Thus, during use, the generated plasma and negative ions form a film adhering to the user's hair and scalp surface, providing overall isolation and protection to reduce the risk of burns and physical friction damage to the user's hair. It also neutralizes static electricity, making the user's hair less frizzy and flyaway, resulting in smoother and easier-to-manage hair. Furthermore, it increases hair shine, effectively removes odors from the hair and scalp, and has a good bactericidal effect on the hair and scalp, ultimately maintaining the user's hair cleanliness and health.

[0116] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.

[0117] Furthermore, in the first embodiment, the comparison Figure 5 , Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the hair care head 40 is a long strip structure with a hollow interior to form a hot air guide cavity 401; the left end face of the hair care head 40 is a mesh structure to form a plurality of hot air outlet grooves 402 that extend through the hot air guide cavity 401.

[0118] Therefore, this application can be used as a hair dryer, which can gather the hot air discharged from the exhaust gap 50 and evenly guide it to the surface of the user's hair through the multiple hot air outlet slots 402, so as to provide even hot air blowing care for the user's hair.

[0119] Furthermore, in the second embodiment, the comparison Figure 8 , Figure 9 and Figure 10 As shown, according to one embodiment of the present invention, the hair care head 40 is a long strip structure with a hollow interior to form a hot air guide cavity 401; a through hole 403 is provided in the middle of the left end face of the hair care head 40, which extends to the hot air guide cavity 401; and multiple comb teeth 404 are evenly protruding to the left around the through hole 403 on the left end face of the hair care head 40.

[0120] Therefore, this application can be used as a hot air comb, which can gather the hot air discharged from the exhaust gap 50 and guide it to the surface of the user's hair through the through hole 403 to blow-dry and care for the user's hair. In this process, multiple comb teeth 404 can also be used to comb the user's hair, and the hot air generating component 30 can also be turned off in this process so that this application can be used as a regular comb.

[0121] In the third embodiment, the comparison Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, according to one embodiment of the present invention, the hair care head 40 is a long strip structure with a hollow interior to form a hot air guide cavity 401; a through hole 403 is provided in the middle of the left end face of the hair care head 40, which extends to the hot air guide cavity 401; a plurality of comb blades 405 are evenly protruding to the left between the upper and lower parts of the through hole 403 on the left end face of the hair care head 40, and a heat-conducting plate 406 is embedded inside each comb blade 405.

[0122] Therefore, the hair care head 40 described in this application can be used as a heated straightening comb. It can gather the hot air discharged from the exhaust gap 50 and guide it to the surface of the user's hair through the through hole 403 to blow-dry and care for the user's hair. During this process, multiple comb blades 405 can be used to straighten the user's hair. During the straightening process, the hot air entering the hot air guide cavity 401 can also conduct heat to multiple heat-conducting plates 406 so that multiple comb blades 405 are heated. In this way, the user's hair can be heated and softened to make the straightening effect better. This process can also turn off the hot air generating component 30 so that this application can be used as an ordinary comb.

[0123] In this regard, it can be clearly stated that in specific implementation, the functions of this application can be switched in multiple ways. It can be used as a hot air hair straightener, a hair dryer, a hot air comb, a regular comb, and a heated hair straightening comb, making its functions truly comprehensive and its uses wide-ranging. It can indeed achieve multiple uses in one piece and is very flexible and versatile in use.

[0124] Preferably, in this technical solution, compared with Figure 1 , Figure 3 and Figure 4 As shown, the upper end face of the upper extension 102 is cut downward to form an upper groove 1022, and the lower bottom face of the lower extension 202 is cut upward to form a lower groove 2022.

[0125] In this regard, in comparison Figure 6 , Figure 9 , Figure 13 and Figure 14 As shown, the hair care head 40 of this application has an upper buckle 407 on the right top wall that can be movably inserted into the upper slot 1022, and a lower buckle 408 on the right bottom wall that can be movably inserted into the lower slot 2022.

[0126] Thus, the hair care head 40 described in this application can be easily installed onto the upper extension 102 and the lower extension 202.

[0127] Preferably, in the technical solution of this application, the upper slot 1022 and the lower slot 2022 are both arranged in the front-back direction, and the upper buckle 407 and the lower buckle 408 are also arranged in the front-back direction, so that they can be correspondingly snapped into the upper slot 1022 and the lower slot 2022 in the front-back direction. In this way, the hair care head 40 of this application is less likely to slip off from the upper extension 102 and the lower extension 202 in the left-right direction, making the use of this application more reliable.

[0128] Meanwhile, in this technical solution, for the hair care head 40 in the third embodiment, multiple comb blades 405 are fixed from front to back on the left side of a connecting rib A409, preferably integrally formed; multiple heat-conducting plates 406 are fixed from front to back on the left side of a connecting rib B410, also preferably integrally formed; the connecting rib A409 is detachably fixed on the left side of the hair care head 40 to clamp the connecting rib B410, and the interior of each of the multiple comb blades 405 is hollow, with an opening at the right end that extends into the interior; the multiple heat-conducting plates 406 are correspondingly embedded in the multiple comb blades 405 through the multiple openings. This facilitates the disassembly, replacement, and maintenance of the integrally formed connecting rib A409 and the multiple comb blades 405, and also facilitates the disassembly, replacement, and maintenance of the integrally formed connecting rib B410 and the multiple heat-conducting plates 406.

[0129] Furthermore, in this technical solution, compared with Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the upper clamping arm 10 includes an upper housing 10a and an upper clamping plate 10b covering the lower part of the front half of the upper housing 10a; the lower clamping arm 20 includes a lower housing 20a and a lower clamping plate 20b covering the upper part of the front half of the lower housing 20a.

[0130] Based on this, in this application, the upper clamping groove 101 is formed by an upward recess in the middle of the lower bottom surface of the upper clamping plate 10b along its length direction; the lower clamping groove 201 is formed by a downward recess in the middle of the upper end surface of the lower clamping plate 20b along its length direction.

[0131] Furthermore, in specific implementation, we will continue to refer to... Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the front half of the upper shell 10a is fitted with an upper air guide duct 80, which has an open lower part and an upper air inlet 801 at the rear end. The periphery of the lower open part of the upper air guide duct 80 is sealed to the upper end face of the upper clamping plate 10b. The upper hot air outlet channel 1011 extends through the upper air guide duct 80.

[0132] Furthermore, in specific implementation, it is still necessary to refer to... Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the lower housing 20a has a lower air guide duct 90 with an open upper part and a lower air inlet 901 at the rear end, and the upper open periphery of the lower air guide duct 90 is sealed to the lower bottom surface of the lower clamping plate 20b; the lower hot air outlet channel 2011 extends through the lower air guide duct 90.

[0133] Therefore, by setting the upper air guide duct 80 and the lower air guide duct 90, the hot air leakage prevention effect is good both inside the upper clamping arm 10 and the lower clamping arm 20.

[0134] Furthermore, in this technical solution, we still refer to... Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the hot air generating component 30 includes an upper heating wire component 301, a lower heating wire component 302, a horizontally placed Y-shaped air guide 303, a motor mounting bracket 304, a high-speed blower motor 305, and a main control device for controlling the operation of the upper plasma / negative ion generating component 60, the lower plasma / negative ion generating component 70, the upper heating wire component 301, the lower heating wire component 302, and the high-speed blower motor 305;

[0135] The upper heating wire component 301 is fixedly installed inside the upper air guide duct 80; the lower heating wire component 302 is fixedly installed inside the lower air guide duct 90; the middle part of the horizontal Y-shaped air guide 303 is made of soft material, its upper front end is connected to the upper air inlet 801 at the rear end of the upper air guide duct 80 to guide hot air to the upper heating wire component 301, its lower front end is connected to the lower air inlet 901 at the rear end of the lower air guide duct 90 to guide hot air to the lower heating wire component 302, and its rear end is provided with a high-speed blower motor 305 with the air blowing direction facing forward; the rear part of the high-speed blower motor 305 extends into the front end of the motor fixing frame 304; the main control device is fixed inside the motor fixing frame 304, and the outer wall of the rear end of the motor fixing frame 304 has an air inlet groove 3041.

[0136] Furthermore, the rear end of the upper housing 10a is hinged to the upper outer wall of the rear part of the motor mounting bracket 304 via an upper pivot 100 arranged in the left-right direction; the rear end of the lower housing 20a is hinged to the lower outer wall of the rear part of the motor mounting bracket 304 via a lower pivot 110 arranged in the left-right direction; the upper wall and lower wall of the middle part of the motor mounting bracket 304 are respectively provided with elastic members 120 for supporting the upper housing 10a above and supporting the lower housing 20a below, so that initially the upper clamping plate 10b and the lower clamping plate 20b can be driven to remain in an open state in the vertical direction.

[0137] Preferably, in this technical solution, the upper wall of the middle part of the motor fixing bracket 304 has an upper mounting hole 3047 opening downward, and the lower wall of the middle part of the motor fixing bracket 304 has a lower mounting hole 3048 opening upward. An upper spring 1201 is fixed upward in the upper mounting hole 3047, and a lower spring 1202 is fixed downward in the lower mounting hole 3048. The upper spring 1201 and the lower spring 1202 together constitute the elastic element 120.

[0138] And compare Figures 17-19 As shown, the front end of the motor mounting bracket 304 is also provided with an opening degree limiting member 130 for controlling the opening degree of the upper housing 10a and the lower housing 20a in the vertical direction.

[0139] Therefore, it can be clearly understood that when the main control device controls the operation of the upper heating wire component 301, the lower heating wire component 302, and the high-speed blower motor 305, the high-speed blower motor 305 can draw air inward and guide the air into the upper air guide duct 80 and the lower air guide duct 90. On the one hand, since the upper heating wire component 301 is fixed in the upper air guide duct 80, when its temperature rises to the preset temperature, it can heat the air guided into the upper air guide duct 80, so as to ultimately achieve the goal of making the generated hot air flow through the upper hot air outlet channel 1011. The system heats, softens, and straightens the upper part of the user's hair that is clamped. On the other hand, since the lower heating wire component 302 is fixed inside the lower air guide tube 90, when its temperature rises to a preset temperature, it can heat the air guided into the lower air guide tube 90. This allows the generated hot air to flow out through the lower hot air outlet channel 2011 to heat, soften, and straighten the lower part of the user's hair that is clamped. The generated hot air can also be conducted to the surface of the user's hair that is clamped through the gaps between the clamped hair, so that the user's hair is heated evenly.

[0140] Furthermore, since the rear end of the upper housing 10a is hinged to the upper outer wall of the motor mounting bracket 304 via an upper pivot 100, and the rear end of the lower housing 20a is hinged to the lower outer wall of the motor mounting bracket 304 via a lower pivot 110; the upper and lower middle walls of the motor mounting bracket 304 are respectively provided with elastic members 120 for supporting the upper housing 10a above and the lower housing 20a below, so that initially the upper clamping plate 10b and the lower clamping plate 20b can be driven to remain in an open state in the vertical direction. The front end of the motor mounting bracket 304 is also provided with an opening degree limiting member 130 for controlling the opening degree of the upper housing 10a and the lower housing 20a in the vertical direction. Thus, initially, the upper clamp 10b and the lower clamp 20b can be kept in an appropriate degree of openness in the vertical direction, so that this application can be presented in a natural open state in advance to prepare to clamp the user's hair for heating, softening and straightening.

[0141] Preferably, in this technical solution, the comparison continues. Figures 17-19As shown, the upper left and right sides of the front end of the motor mounting bracket 304 are respectively provided with front upper limit blocks, and the lower left and right sides of the front end of the motor mounting bracket 304 are respectively provided with front lower limit blocks. The two front upper limit blocks and the two front lower limit blocks together constitute the opening degree limiting member 130. The two front upper limit blocks extend to the upper rear of the upper clamping plate 10b, and the two front lower limit blocks extend to the lower rear of the lower clamping plate 20b. When the two upper springs push the upper housing 10a, the rear end of the upper clamping plate 10b will move upward by a preset stroke. At this time, its upper rear part will abut against the lower bottom surface of the two front upper limit blocks. Simultaneously, when the two lower springs push the lower housing 20a, the rear end of the lower clamping plate 20b will move downward by a preset stroke. At this time, its lower rear part will abut against the upper end surface of the two front lower limit blocks.

[0142] In this way, the two upper front limit blocks and the two lower front limit blocks constituting the opening degree limiting member 130 are used to control the opening degree of the upper shell 10a and the lower shell 20a in the vertical direction, so that the upper clamping plate 10b and the lower clamping plate 20b can always maintain a suitable degree of opening in the vertical direction when they are not gripped tightly in opposite directions, so as to be used for hair clamping.

[0143] Preferably, in this technical solution, a connecting shaft 3049 is fixed between the left front part and the right front part of the motor mounting bracket 304. During assembly, the connecting shaft 3049 will be located inside the front of the horizontal Y-shaped air guide 303, so that the overall structure of the motor mounting bracket 304 is more stable and less likely to fall apart.

[0144] Furthermore, in specific implementation, we will continue to refer to... Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the rear end of the motor mounting bracket 304 is wrapped with a dust filter 140 outside the air inlet slot 3041, and the dust filter 140 is detachably fitted with an air inlet mesh cover 150.

[0145] In a further preferred embodiment of this technical solution, the air inlet mesh cover 150 is secured to the dust filter 140 by magnetic attraction or snap-fit, thereby facilitating the quick disassembly of the air inlet mesh cover 150 and enabling regular or irregular cleaning and maintenance of the dust filter 140.

[0146] Furthermore, in this technical solution, it is still in comparison with... Figure 3 and Figure 4As shown, according to one embodiment of the present invention, an upper heat-conducting aluminum sheet 160 for stabilizing heat energy during pulling is fixedly provided on the lower right part of the upper clamping plate 10b along its length direction, and a lower heat-conducting aluminum sheet 170 for stabilizing heat energy during pulling is fixedly provided on the upper right part of the lower clamping plate 20b along its length direction. A soft rubber strip 1701 abutting against the upper end face of the lower heat-conducting aluminum sheet 170 is fixedly provided on the lower bottom surface of the upper heat-conducting aluminum sheet 160 along its length direction, and / or a soft rubber strip 1701 abutting against the lower bottom surface of the upper heat-conducting aluminum sheet 160 is fixedly provided on the upper end face of the lower heat-conducting aluminum sheet 170 along its length direction.

[0147] Thus, in comparison Figure 2 and Figure 16 As shown, after the upper heating wire component 301 and the lower heating wire component 302 are heated, the heat can be emitted and conducted to the surface of the upper heat-conducting aluminum sheet 160 and the lower heat-conducting aluminum sheet 170 through hot air. This allows the heat energy to be stabilized better through the upper heat-conducting aluminum sheet 160 and the lower heat-conducting aluminum sheet 170 during the hair straightening process when using this application. This results in a better hair straightening effect. Furthermore, by setting the soft adhesive strip 1701, the user's hair can be gripped better and is less likely to slip, which facilitates better hot air straightening of the user's hair. Thus, the overall effect of this application can be optimized.

[0148] It should be added that, in specific implementation, comparison should be made with... Figure 2 As shown, according to one embodiment of this utility model, the outer wall of the motor mounting bracket 304 is provided with a power switch 3042, a fan speed adjustment key 3043, a heating element temperature adjustment key 3044, a fan airflow adjustment key 3045, and a display screen 3046 connected to the main control device. The display screen 3046 can be a hidden display screen, that is, embedded in the outer wall of the motor mounting bracket 304 to provide good protection and prevent it from being scratched or damaged by external objects. The display screen 3046 is used to display the wind speed of the high-speed blower motor 305, the heating temperature of the upper heating wire component 301 and the lower heating wire component 302, and also to display the operating parameters such as the airflow level of the high-speed blower motor 305, so as to make the operation of this application more flexible and intuitive.

[0149] Other embodiments, etc., will not be described here.

[0150] In summary, the multi-head intelligent hot air hair straightener 1000 provided in this application, in its specific implementation, optimizes and improves the structure of the upper clamp arm 10 and the lower clamp arm 20 so that they have corresponding upper extension 102 and lower extension 202, making it convenient to connect the hair care head 40. When the hair care head is not in use, this application can be used as a hot air hair straightener. When the hair care head 40 is assembled, this application can be used as a hot air hair dryer to blow-dry and care for the user's hair with hot air, making this application multi-functional and flexible in use.

[0151] Furthermore, compared to existing traditional hair straighteners, this application features an upper clamping slot 101 and a lower clamping slot 201 to clamp the user's hair. Specifically, an upper partition 180 is installed inside the upper clamping slot 101 along its length, and a lower partition 190 is installed inside the lower clamping slot 201 along its length. An upper exhaust channel is formed between the upper clamping slot 101 and the upper partition 180, a lower exhaust channel is formed between the lower clamping slot 201 and the lower partition 190, and a middle exhaust channel and hair clamping space are formed between the upper partition 180 and the lower partition 190. In this way, a certain hot air flow space can be formed between the upper clamping slot 101 and the lower clamping slot 201, so that the hot air entering it can be blown as evenly as possible onto the surface of each strand of the user's hair clamped therein to heat it, resulting in good uniform heating of the user's hair and a good straightening effect.

[0152] Furthermore, when the upper clamping arm 10 and the lower clamping arm 20 are closed to clamp the user's hair, the upper hot air outlet channel 1011 is located at the bottom right side of the upper clamping groove 101, allowing the hot air outlet therein to flow as far to the left as possible along the formed hot air flow space to heat the user's hair. Similarly, the lower hot air outlet channel 2011 is located at the bottom right side of the lower clamping groove 201, allowing the hot air outlet therein to flow as far to the left as possible along the formed hot air flow space to heat the user's hair. In this way, the hot air utilization efficiency of this application is high.

[0153] In addition, this application uses hot air to heat and soften the user's hair in order to straighten it. Compared with the traditional method of using the entire heating plate to clamp the user's hair for heating and softening, this application is safer and less likely to cause high temperature burns to the user's hair or burns to the user's scalp or the operator's hands.

[0154] Furthermore, based on traditional hair straighteners, this application adds an upper plasma / negative ion generating component 60, a lower plasma / negative ion generating component 70, multiple upper plasma / negative ion needles 601, and multiple lower plasma / negative ion needles 701. This allows the straightener to generate a large number of plasma / negative ions when powered on. These plasma / negative ions are then blown by hot air and adhere to the user's hair or scalp. During use, the generated plasma and negative ions form a film adhering to the user's hair and scalp, providing overall protection and reducing the risk of burns and physical friction damage. It also neutralizes static electricity, making the user's hair less frizzy and flyaway, resulting in smoother, easier-to-manage hair. It also increases hair shine, effectively removes odors from the hair and scalp, and has a good antibacterial effect on the hair and scalp, ultimately maintaining the user's hair cleanliness and health.

[0155] Furthermore, in practical implementation, the functions of this application can be switched in multiple ways. It can be used as a hot air straightener, a hair dryer, a hot air comb, a regular comb, and a heated hair straightener, making its functions truly comprehensive and its uses wide-ranging. It can indeed achieve multiple uses in one piece and is very flexible and versatile in use.

[0156] Meanwhile, in this technical solution, the air inlet mesh cover 150 is fixed to the dust filter 140 by magnetic attraction or snap-fit, so as to facilitate the quick disassembly of the air inlet mesh cover 150, so as to facilitate the regular or irregular cleaning and maintenance of the dust filter 140.

[0157] Furthermore, after the upper heating wire component 301 and the lower heating wire component 302 are heated, the heat can be emitted and conducted to the surfaces of the upper heat-conducting aluminum sheet 160 and the lower heat-conducting aluminum sheet 170 through hot air. This allows the heat energy to be better stabilized through the upper heat-conducting aluminum sheet 160 and the lower heat-conducting aluminum sheet 170 during the hair straightening process when the user uses this application. This results in a better hair straightening effect. In addition, by setting the soft adhesive strip 1701, the user's hair can be better gripped and less likely to slip, so as to better straighten the user's hair with hot air. Thus, the overall use effect of this application can be optimized.

[0158] Therefore, the multi-head intelligent hot air hair straightener 1000 provided in this application is indeed highly practical and has excellent performance.
