Description

Technical Field

[0001] The present invention relates to the field of hairdressing equipment, and in particular to a hair dryer and a control method thereof. Background Art

[0002] Hair dryers are small household appliances that are used very frequently in people's daily lives. Hair dryers are mainly used for drying and shaping hair.

[0003] The hair dryers used in daily life at home are all in the form of hair dryers, which include a handle and a hair dryer head. The fan blades in the hair dryer rotate to generate wind. When blowing hair, the user points the hair dryer head at the part of the hair that needs to be dried, and the moisture on the surface of the hair can be taken away by the hot air, thereby achieving drying. However, when the user uses the above hair dryer to blow hair, the part of the hair that is directly blown by the wind will flutter and swing irregularly due to the disturbance and impact of the hot air, making the hair easy to fly and become rough after drying. Summary of the invention

[0004] In order to prevent hair from becoming frizzy and rough after being dried by a hair dryer, the present invention provides a hair dryer and a control method thereof.

[0005] In a first aspect, the present invention provides a hair dryer, which adopts the following technical solution:

[0006] A hair dryer comprises a handle for generating hot air and a hair dryer head mounted on the handle for guiding the hot air to the hair of a user, wherein the hair dryer head comprises a hair dryer shell and an air guide member rotating in an inner cavity of the hair dryer shell; the hair dryer head comprises a hair dryer portion and an adsorption portion connected to the hair dryer portion and used for adsorbing hair; the hair dryer portion comprises a hair dryer port, the adsorption portion is a hollow cylinder and has an arc-shaped adsorption surface, and the air outlet direction of the hair dryer port is tangent to the arc-shaped adsorption surface; the air guide member comprises an air inlet for the wind generated by the handle to enter, and an air outlet for guiding the wind to the hair dryer port.

[0007] By adopting the above technical solution, the hair dryer shell is composed of a blowing part and a suction part, the blowing port is arranged on the blowing part, and the suction part has a curved suction surface. Since the wind blown out by the blowing part is tangent to the curved suction surface, the wind can be sucked on the curved suction surface through the Coanda effect, thereby forming a negative pressure on the curved suction surface. When the hair dryer blows the hair, the hair can be sucked on the curved suction surface and is not easily messed up by the wind. When the hair is blown dry, the hair is not easy to fly and become rough.

[0008] Optionally, the air outlets are symmetrically arranged on both sides of the blowing part, and the inner cavity of the blowing shell is provided with a partition, and the partition and the blowing shell are surrounded by a first air outlet channel and a second air outlet channel to form a symmetrically distributed first air outlet channel and a second air outlet channel, and the first air outlet channel and the second air outlet channel correspond to and are connected with the air outlets on both sides one by one; the air inducing member has an anti-flying mode and a blowing mode, and in the anti-flying mode, the air outlet is connected with the first air outlet channel or the second air outlet channel, and in the blowing mode, the air outlet is connected with both the first air outlet channel and the second air outlet channel.

[0009] By adopting the above technical solution, the hair dryer has a blow-drying mode and an anti-flying mode. In the blow-drying mode, both sides of the blowing part can blow air, and the hair dryer can blow air directly to the hair; while in the anti-flying mode, the blowing part can select the blowing outlet on one side to blow air. Since the blowing outlet is provided on both sides, when the user uses the above-mentioned hair dryer nozzle to blow the hair, no matter from which angle the hair is blown, the blowing outlet can be used for blowing, thereby facilitating the user's operation.

[0010] Optionally, the partition portion includes an air isolation ring mounted on the outside of the air inducing member and an air guide plate integrally connected to the blowing portion; the air guide plate has an arc-shaped air guide surface facing the air outlet, and the arc-shaped air guide surface is bent toward the blowing outlet to guide hot air into the blowing outlet.

[0011] By adopting the above technical solution, when the wind blows out from the air outlet, the wind can enter the air outlet along the arc wind guide surface, reducing the probability of the wind returning on the arc wind guide surface and colliding with the wind blown out of the air outlet; and because the wind guide plate and the blowing part are integrally arranged, when the hot air blown out by the air guide member blows on the arc wind guide surface, the wind guide plate can generate heat and transfer the heat to the blowing part, and finally the blowing part can generate heat. When the surface of the blowing part is pressed on the hair, the hair can be dried faster.

[0012] Optionally, the hair dryer head also includes an adjusting head arranged on the top of the hair dryer housing and connected to the air guide member for driving the air guide member to rotate so as to be in an anti-flying mode or a blowing mode, and the adjusting head is provided with a locking component for locking the air guide member in the anti-flying mode or the blowing mode.

[0013] By adopting the above technical solution and arranging the adjustment head on the top of the hair dryer housing, it is easier for the user to switch the mode of the air induction member, and the user only needs to adjust the adjustment head when using the hair dryer.

[0014] Optionally, the circumferential angle of the arc-shaped adsorption surface is 100° to 150°.

[0015] By adopting the above technical solution, when the circumferential angle of the arc-shaped adsorption surface is between 100° and 150°, the winds blown out from the air outlets on both sides of the air blowing part do not interfere with each other. In addition, the surface area of ​​the arc-shaped adsorption surface is large, and more hair can be adsorbed.

[0016] Optionally, the blowing portion has a pressing surface on a side of the blowing port away from the adsorption portion, which is in contact with and flattened by the user's hair; and a ventilation cavity is provided between the plane where the pressing surface is located and the arc-shaped adsorption surface.

[0017] By adopting the above technical solution, when using the hair dryer, the hair blown by the wind can be pressed by the pressing surface and thus flattened, so that the hair is not easily moved. By providing the ventilation cavity, the air outlet is not easily blocked by the hair, so that the air blown out of the air outlet has space to flow and the hair is adsorbed on the arc-shaped adsorption surface, so that the hair is not easily lifted when drying.

[0018] Optionally, the handle has an installation groove for inserting the hair dryer head, the inner wall of the installation groove is provided with a connecting block and an elastic protrusion, the hair dryer head is provided with an entry groove for axial insertion of the connecting block and a locking groove connected to the tail of the entry groove and for the connecting block to be circumferentially rotated and engaged; the handle is also provided with a clamping groove for elastic engagement of the elastic protrusion and corresponding to the locking groove.

[0019] By adopting the above technical solution, when installing the hair dryer head on the handle, the hair dryer head is axially inserted into the handle and rotated circumferentially, the connecting block can enter from the entry groove and rotate to lock into the locking groove, and when the connecting block is located in the locking groove, the handle can drive the elastic protrusion to deform and snap into the snap-in groove, so that the connecting block can be firmly locked in the locking groove, and the hair dryer head is not easy to be directly pulled out axially from the handle.

[0020] In a second aspect, the present application provides a control method for a hair dryer, which adopts the following technical solution:

[0021] A control method for a hair dryer, applied to any of the above-mentioned hair dryers, wherein the wind shielding ring is rotatably sleeved on the air induction member so that the circumferential angle of the portion of the inner wall of the adsorption portion located in the first air outlet channel or the second air outlet channel can be adjusted, the wind shielding ring is provided with a one-way air hole and the adsorption portion is provided with an air induction hole, the one-way air hole allows wind to enter the inside of the air induction member from the outside of the air induction member; and further comprising:

[0022] When blowing hair, obtain the humidity information of the hair surface and the head image information;

[0023] Determine wind temperature information corresponding to the humidity information according to the humidity information, and match the heating power according to the wind temperature information;

[0026] The angle adjustment value of the wind shield is matched according to the characteristic length of the hair so that the hot air can heat the inner wall of the adsorption part;

[0027] The wind shield is controlled to rotate according to the angle adjustment value, and the hair dryer is controlled to blow air according to the preset reference blowing force and heating power so that the hair features are adsorbed on the adsorption part and dried;

[0028] If the hair feature is greater than the length of short hair, the one-way air hole is controlled to open, the wind shield is controlled to rotate according to the preset maximum angle, and the hair dryer head is controlled to blow air according to the benchmark blowing force and heating power so that the hair feature is adsorbed on the adsorption part and the air duct assists in adsorbing the hair feature.

[0029] By adopting the above technical solution, the system can control the hair dryer to blow hair in different ways according to the different hair lengths of the users. For short hair, the system can adjust the angle of the wind shield according to the length of the short hair, so that the hot air blown out of the air outlet can heat the inner wall of the adsorption part. When the short hair is adsorbed on the adsorption part, the heat of the adsorption part can dry the hair; and for long hair, the system can control the opening of the one-way air holes, so that the air duct holes can assist in adsorbing the hair, and the hair that cannot be adsorbed by the adsorption part can be adsorbed by the air duct holes, thereby preventing the long hair from flying away.

[0030] Optionally, when the user needs to switch the air outlet for blowing, the automatic switching method of the air outlet includes:

[0031] When the user holds the handle of the hair dryer, trigger information of the handle is obtained;

[0032] Determine, according to the trigger information, the body side information corresponding to the trigger information where the arm grasping the hair dryer is located;

[0034] Based on the abutment signal being consistent with the preset reference signal, continuing to blow air;

[0035] Based on the inconsistency between the abutment signal and the reference signal, after a preset waiting time, reacquire the abutment signal and determine whether the abutment signal is consistent with the reference signal;

[0036] If and only if the abutment signal is inconsistent with the reference signal, determining whether there is trigger information;

[0037] Based on the absence of trigger information, stop blowing;

[0038] Based on the trigger information, the air outlet is controlled to switch for blowing.

[0039] By adopting the above technical solution, the system can determine which handheld hair dryer the user is using for blow-drying hair based on the user's palm prints, and determine on which side of the head the hair dryer is blowing hair based on the contact signal when the hair dryer is in contact with the hair, so that the hair dryer can automatically switch the blowing outlet for blowing when the user is blow-drying hair, making it convenient for the user to blow hair at any angle.

[0044] If the hair-combing resistance is greater than the preset reference resistance, it is defined as a hair knot, and the corresponding force-bearing claw is determined according to the hair-combing resistance;

[0045] The distance between the force-bearing claw and the force-bearing claw adjacent thereto is adjusted according to a preset spreading distance to separate the tangled hair.

[0046] By adopting the above technical solution, the system can determine whether the user's hair is tangled based on the combing resistance, and drive the combing claw mechanism to open the tangled parts of the hair so that the tangled hair is separated. By adopting the above method, the user's hair can be smoother.

[0047] In summary, the present application includes at least one of the following beneficial technical effects:

[0048] 1. By providing a blowing port in the blowing part and the adsorption part having an arc-shaped adsorption surface, the wind blown out of the blowing part is tangent to the arc-shaped adsorption surface, and the wind can be adsorbed on the arc-shaped adsorption surface, thereby forming a negative pressure on the arc-shaped adsorption surface, so that when the hair dryer blows the hair, the hair can be adsorbed on the arc-shaped adsorption surface and is not easily blown messy by the wind, and the hair is not easy to fly and become rough when the hair is blown dry;

[0049] 2. The hair dryer has a blow-drying mode and an anti-flying mode. In the blow-drying mode, both sides of the blower can blow air, and the hair dryer can blow air directly to the hair; while in the anti-flying mode, the blower can select the blow outlet on one side to blow air. Since the blow outlet is set on both sides, when the user uses the above-mentioned hair dryer nozzle to blow the hair, no matter from which angle the hair is blown, the blow outlet can be used for blowing, which is convenient for the user to operate;

[0050] 3.

[0060] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0061] The embodiment of the present application discloses a hair dryer.

[0062] Reference Figure 1 A hair dryer comprises a handle 1 and a hair dryer head 2 detachably mounted on the handle, wherein the handle 1 is used for being held by a user and can generate wind by electricity, and the hair dryer head 2 is used for guiding the wind generated by the handle to blow toward the user's hair to dry the hair.

[0063] Reference Figure 2 The blowing head 2 includes a blowing shell 21, an air inducing member 22, a partition 23 and an adjusting head 24. The air inducing member 22 and the partition 23 are both installed in the inner cavity of the blowing shell 21, and the adjusting head 24 is installed on the top of the blowing shell 21 and connected to the air inducing member 22.

[0064] Reference Figure 2 and Figure 3 The blowing housing 21 includes a blowing portion 211 and an adsorption portion 212 connected to the blowing portion 211. The blowing portion 211 is provided with a blowing port 213. In the present embodiment, the number of the blowing ports 213 is two and they are symmetrically arranged on both sides of the blowing portion 211.

[0065] The adsorption portion 212 is a hollow cylinder having an arc-shaped adsorption surface 214 , the circumferential angle of the arc-shaped adsorption surface 214 is between 100° and 150°. In the present embodiment, the circumferential angle of the arc-shaped adsorption surface 214 is 120°, so that the adsorption area of ​​the adsorption portion 212 is larger.

[0066] The air induction member 22 rotates in the inner cavity of the air blowing shell 21 and is coaxial with the adsorption portion 212. The air induction member 22 passes through the bottom of the air blowing shell 21, and an air inlet 221 is provided at the bottom of the air induction member 22, and the air inlet 221 is used to supply air to enter. An air outlet 222 is provided on the side of the air induction member 22, and the air outlet 222 is used to blow out the air entering from the air inlet 221. The air outlet 222 is provided along the length direction of the air induction member 22, and the shape of the air outlet 222 can be a whole long strip, or a plurality of holes provided at intervals, and the shape of the holes is arbitrary as long as the air can be blown out.

[0067] The partition 23 includes an air shielding ring 231 and an air guide plate 232. The air shielding ring 231 is sleeved on the outside of the air induction member 22 and connected to the inner wall of the adsorption portion 212. The cross section of the air shielding ring 231 is an arc shape so that the air outlet 222 of the air induction member 22 can only blow out air when it is facing the gap of the air shielding ring 231. The wind guide plate 232 is connected to the inner wall of the blowing part 211, and the wind guide plate 232, the wind shielding ring 231 and the blowing outer shell 21 are surrounded by a first air outlet channel 25 and a second air outlet channel 26 that are symmetrically distributed. The first air outlet channel 25 and the second air outlet channel 26 correspond one-to-one to and are connected with the blowing ports 213 on both sides, and the wind guide plate 232 and the wind shielding ring 231 form air gates 27 that correspond one-to-one to the first air outlet channel 25 and the second air outlet channel 26 respectively. When the air outlet 222 of the air induction member 22 is connected with the air gate 27, the air blown out by the air induction member 22 can go out from the blowing port 213.

[0068] In this embodiment, the air guide member 22 has three different gears when rotating, including a left gear, a middle gear and a right gear, wherein the left gear and the right gear are both anti-flying mode, and the middle gear is a blowing mode. When the air guide member 22 rotates to the anti-flying mode, the air guide member 22 is connected with the first air outlet channel 25 or the second air outlet channel 26, and the wind blown out from the air outlet 222 of the air guide member 22 can flow through the first air outlet channel 25 or the second air outlet channel 26 and blow out from the blowing port 213. When the air guide member 22 rotates to the blowing mode, the air guide member 22 is connected with both the first air outlet channel 25 and the second air outlet channel 26, and the wind blown out from the air outlet 222 of the air guide member 22 can pass through the first air outlet channel 25 and the second air outlet channel 26 at the same time, and blow out from the blowing ports 213 on both sides of the blowing portion 211 at the same time.

[0069] Furthermore, the air guide plate 232 is integrally connected with the blowing part 211 and has an arc-shaped air guide surface 233, which can be directly opposite to the air outlet 222 of the air inducing member 22 and bends toward the air outlet 213. When the wind blows out from the air outlet 222, the wind can enter the air outlet 213 along the arc-shaped air guide surface 233, thereby reducing the collision of the air flow in the inner cavity of the blowing housing 21. And when the hot air blown out by the air inducing member 22 blows on the arc-shaped air guide surface 233, the air guide plate 232 can generate heat and transfer the heat to the blowing part 211, thereby causing the blowing part 211 to generate heat.

[0070] Furthermore, the blowing part 211 has a pressing plane 215 on the side of the blowing port 213 away from the adsorption part 212. When the user blows the hair through the hair dryer, the pressing plane 215 presses on the hair and moves along the direction of the hair. The air outlet direction of the blowing port 213 is tangent to the arc-shaped adsorption surface 214, and there is a ventilation cavity 28 between the plane where the pressing plane 215 is located and the arc-shaped adsorption surface 214. The ventilation cavity 28 refers to the gap between the user's hair and the adsorption part 212 at the outlet of the blowing port 213.

[0071] When the wind is blown out from the blowing port 213 of the blowing housing 21, the wind can enter the ventilation cavity 28 and adhere to the arc-shaped adsorption surface 214 through the Coanda effect, forming a negative pressure on the arc-shaped adsorption surface 214. When the user uses the hair dryer to blow the hair and smooth the hair, the pressing surface 215 first flattens the hair that has been blown, and the part of the hair that has not been pressed can be adsorbed on the arc-shaped adsorption surface 214 under the action of the negative pressure and dried by the wind blown out of the blowing port 213, so that the hair is not easy to fly.

[0072] Reference Figure 2 and Figure 4 The adjusting head 24 drives the air inducing member 22 to rotate so that the air inducing member 22 can be switched between the anti-flying mode and the blowing mode, and the adjusting head 24 is provided with a locking assembly 3 for locking the air inducing member 22 in the anti-flying mode or the blowing mode. In this embodiment, the locking assembly 3 includes a plunger head 31 and a plunger spring 32, the plunger head 31 is telescopically mounted on the top of the blowing housing 21, and the plunger spring 32 drives the plunger head 31 to always have a tendency to be stuck into the adjusting head 24 to lock the air inducing member 22 in the anti-flying mode or the blowing mode.

[0073] Reference Figure 1 and Figure 5 In order to facilitate the assembly and disassembly of the hair dryer head 2 from the handle 1, a connection structure is provided between the hair dryer head 2 and the handle 1. The handle 1 is provided with a mounting groove 11 for inserting the hair dryer housing 21, and the inner wall of the mounting groove 11 is provided with a connecting block 12 and an elastic protrusion 13. The hair dryer head 2 is provided with a connecting channel 4 matched with the connecting block 12 and a clamping groove 5 matched with the elastic protrusion 13 on the outer wall of the hair dryer housing 21.

[0074] The connecting channel 4 is L-shaped, and includes an entry slot 41 and a locking slot 42. The entry slot 41 is opened along the axial direction of the blowing housing 21, and the locking slot 42 is opened along the circumferential direction of the blowing housing 21, and the locking slot 42 is communicated with the tail of the entry slot 41.

[0075] When the hair dryer head 2 is installed on the handle 1 , the hair dryer head 2 is first axially inserted into the installation groove 11 , at which time the connecting block 12 can axially enter along the entry groove 41 , and then the hair dryer head 2 is circumferentially rotated, at which time the connecting block 12 can circumferentially slide into the locking groove 42 .

[0076] The snap-fit ​​groove 5 corresponds to the locking groove 42. When the connecting block 12 is located in the locking groove 42, the hair dryer housing 21 can drive the elastic protrusion 13 to deform and make the elastic protrusion 13 snap into the snap-fit ​​groove 5, thereby further locking the connecting block 12 in the locking groove 42, and the hair dryer head 2 cannot be directly pulled out axially from the handle 1.

[0077] Based on the same inventive concept, an embodiment of the present invention provides a method for controlling a hair dryer.

[0078] Reference Figure 6 , a control method for a hair dryer comprises the following steps:

[0079] In this embodiment, the wind shield ring can rotate on the outside of the air inducing member 22 when driven by a micro motor, so that a portion of the inner wall of the adsorption portion 212 can be in the first air outlet channel 25 or the second air outlet channel 26, and the circumferential angle of the inner wall of the adsorption portion 212 can be adjusted with the rotation of the wind shield ring, and the hot air can heat the inner wall of the adsorption portion 212.

[0080] A one-way air hole is provided on the side of the wind shielding ring away from the air outlet 222 of the air inducing member 22, and an air inducing hole is provided at the position of the adsorption portion 212 corresponding to the one-way air hole, and the one-way air hole allows wind to enter the inner side from the outer side of the wind shielding ring. When the system controls the one-way air hole to be opened, due to the negative pressure of the inner cavity, wind can be sucked in from the air inducing hole and enter the inner cavity from the one-way air hole.

[0081] Step S100: when blowing hair, obtaining humidity information of the hair surface and head image information.

[0082] The humidity information refers to the humidity of the hair and is used to measure the moisture content on the surface of the user's hair. The humidity information is obtained through a humidity sensor set on the hair dryer.

[0083] The head image information refers to the head image of the user obtained by the miniature camera installed on the hair dryer, including all positions above the shoulders of the user, and the head image includes the user's hair. When the user holds the hair dryer and raises it to the head, the camera can scan the entire head of the user to obtain the head image information.

[0084] Step S101: determining wind temperature information corresponding to the humidity information according to the humidity information, and matching the heating power according to the wind temperature information.

[0085] The wind temperature information refers to the temperature of the hot air blown out by the hair dryer. The wind temperature information corresponds to the humidity information. The greater the humidity information, the higher the wind temperature information.

[0086] Heating power refers to the power required by the hair dryer to produce wind of a specific temperature. The heating power is proportional to the wind temperature information. The higher the wind temperature information, the greater the heating power.

[0087] Step S102: determining whether the hair feature is greater than a preset short hair length according to the head image information and the preset hair feature.

[0088] The preset short hair length is a reference value set by technicians to measure whether the length of the user's hair is short hair for this hair dryer. When the hair feature is less than the short hair length, it means that the hair feature is short hair, which will not be elaborated here.

[0089] By matching and analyzing the head image information and hair features through image recognition analysis, the length of the user's hair features can be determined. Then, the hair features are compared with the length of short hair to determine whether the user's hair is short hair. The blowing methods for long hair and short hair are different.

[0090] Step S1031: If the hair feature is not greater than the short hair length, determine the hair feature length based on the head image information.

[0091] If the hair feature is not greater than the short hair length, it means that the user has short hair. The hair feature length refers to the length of the user's hair. The head image information and the hair feature are matched and analyzed by the image recognition analysis method to determine the hair feature length.

[0092] Step S10311: adjusting the angle of the wind shield ring according to the characteristic length of the hair so that the hot air can heat the inner wall of the adsorption portion 212 .

[0093] In this embodiment, when drying short hair, the short hair can be completely adsorbed on the adsorption portion 212 of the hair dryer. At this time, the wind shield is rotated and adjusted so that the adsorption portion 212 adsorbing the short hair can generate heat.

[0094] The angle adjustment value refers to the rotation angle of the windshield when the micro motor rotates and adjusts the windshield. The area swept by the windshield when it rotates is a fan-shaped area. The characteristic length of the hair is equivalent to the arc length of the fan. The angle adjustment value is the arc of the fan. When the hair dryer size standard is known, the angle adjustment value can be calculated according to the arc length and arc formula of the fan through the characteristic length of the hair.

[0095] Step S10312: Control the wind shield to rotate according to the angle adjustment value, and control the hair dryer head 2 to blow air according to the preset reference blowing force and heating power so that the hair features are adsorbed on the adsorption portion 212 and dried.

[0096] The reference blowing force is the force of wind when the hair dryer blows hair, which is set by the technician. The reference blowing force is selected by the user when turning on the hair dryer, and will not be described in detail here.

[0097] When drying short hair, the system first controls the wind shield to rotate according to the angle adjustment value so that the position where the adsorption portion 212 adsorbs the short hair can generate heat, and then blows the short hair according to the reference blowing force and heating power to dry the hair.

[0098] Step S1032: If the hair feature is greater than the short hair length, control the one-way air hole to open, control the wind shield to rotate according to the preset maximum angle, and control the hair dryer head 2 to blow air according to the reference blowing force and heating power so that the hair feature is adsorbed on the adsorption part 212 and the air duct assists in adsorbing the hair feature.

[0099] If the hair feature is longer than the short hair length, it means that the user has long hair. For long hair, since the circumferential angle of the area where the adsorption part 212 can adsorb long hair is insufficient, the system opens the one-way air hole, so that part of the hair that cannot be adsorbed by the adsorption part 212 can be assisted by the air induction hole. In addition, at this time, the system controls the wind shield to be at the maximum angle, so that the adsorption part 212 can generate heat in the largest range.

[0100] Reference Figure 7 When the user blows dry different parts of the head, the blow outlet 213 may need to be switched. The automatic switching method of the blow outlet 213 includes the following steps:

[0101] Step S200: When the user holds the handle 1 of the hair dryer, trigger information of the handle is obtained.

[0102] The trigger information refers to the information generated by the handle when the user grasps the handle with his palm. In this embodiment, the trigger information is generated by the palm prints. When the user grasps the hair dryer, the miniature camera on the hair dryer can capture and identify the palm prints of the user.

[0103] Step S201: determining, according to the trigger information, information of the body side where the arm grasping the hair dryer corresponding to the trigger information is located.

[0104] Body side information refers to the left or right side of the body. Since the palm prints on the two hands of a person are symmetrical when grasping an object, it is possible to determine whether the palm print is located on the left or right hand of the user's body based on the palm print, thereby determining which hand the user is grasping the hair dryer with.

[0105] Step S202: Match the corresponding blowing port 213 according to the body side information, control the blowing port 213 to blow air according to the reference blowing force, and obtain the contact signal between the blowing part 211 and the hair feature on the corresponding side of the blowing port 213 in real time.

[0106] After the body side information is determined, the gear of the hair dryer is adjusted to the corresponding blow outlet 213 according to the body side information. According to habit, when the right hand holds the hair dryer, the hair on the right side of the head is usually blown dry. Therefore, when the hair dryer is started, the system first selects the blow outlet 213 of the hair dryer for blowing according to the body side information.

[0107] In the subsequent drying process, if the user's body side information is consistent with the blowing port 213, and the user does not change hands and blows air to the hair on the opposite side of the head, the system will make further adjustments through the contact signal. The contact signal refers to the signal generated by the pressure when the blowing part 211 of the hair dryer contacts the user's hair, and the contact signal is triggered by the pressure detected by the pressure sensor.

[0108] When the blowing parts 211 on both sides of the hair dryer abut against the hair, both abutment signals are generated, but the two abutment signals are different, so as to distinguish which side of the hair dryer generates the abutment signal.

[0109] Step S2031: based on the contact signal being consistent with the preset reference signal, continue blowing.

[0110] The reference signal is a reference signal generated when the blowing part 211 on the corresponding side contacts the hair and is set by a technician, and will not be described in detail here.

[0111] If the contact signal is consistent with the reference signal, it means that the air outlet 213 corresponds to the body side information, and the air outlet 213 is also blowing air to the head hair corresponding to the body side information, and the wind blown out by the air outlet 213 can blow onto the hair.

[0112] Step S2032: Based on the inconsistency between the abutting signal and the reference signal, after a preset waiting time, reacquire the abutting signal and determine whether the abutting signal is consistent with the reference signal.

[0113] If the contact signal is inconsistent with the reference signal, it means that the user may not be using the hair dryer at this time, so there is no signal. It is also possible that the user is blowing the hair on the other side of the head, but the position of the blowing port 213 is opposite, and the wind blown out of the blowing port 213 cannot blow on the hair.

[0114] In view of the above situation, the system will detect the contact signal again after the waiting time. The waiting time is the buffer time set by the technician for waiting to re-acquire the contact signal, which will not be described in detail here.

[0115] Step S20321: When and only when the contact signal is inconsistent with the reference signal, determine whether there is trigger information.

[0116] If the contact signal obtained at this time is still inconsistent with the reference signal, it is necessary to determine whether the user is still using the hair dryer. At this time, the system obtains trigger information again. If the user is still holding the hair dryer, the user's palm print can be obtained, otherwise the user's palm print cannot be obtained.

[0117] Step S2041: Stop blowing based on the absence of trigger information.

[0118] If there is no trigger information, it means that the user has finished using the hair dryer, and the system controls the hair dryer to stop blowing.

[0119] Step S2042: Based on the trigger information, the air outlet 213 is controlled to switch to blow air.

[0120] If the trigger information can still be detected, it means that the user wants to blow the hair on the opposite side of the head, and the system controls the air outlet 213 to switch.

[0121] In this embodiment, if the user switches the hair dryer to the other hand, the trigger information changes and the system will perform control according to step S202 to reselect the air outlet 213 .

[0122] Reference Figure 8 When users blow dry their hair, the hair may become tangled. The method for dealing with tangled hair includes the following steps:

[0123] Step S300: determining the hair coverage thickness according to the head image information, hair features and preset scalp features.

[0124] Scalp features refer to the location of the user's scalp.

[0125] The hair coverage thickness refers to the distance from the hair surface to the scalp. The head image information is analyzed by image recognition analysis. The hair features and scalp features are determined at the head image information position. Then, the hair coverage thickness between the hair features and scalp features can be determined based on the hair features and scalp features.

[0126] Step S301: determining the corresponding unfolding angle of the combing claw mechanism preset in the blowing part 211 according to the hair covering thickness.

[0127] In this embodiment, a combing claw mechanism is rotatably provided on the blowing part 211 of the hair dryer. The combing claw mechanism can comb the hair when the hair dryer blows air along the hair. The combing claw mechanism is driven by a micro motor.

[0128] The spreading angle refers to the angle at which the comb claw mechanism rotates and extends out of the blowing part 211. The larger the spreading angle, the longer the comb claw extends out of the blowing part 211. The spreading angle of the comb claw mechanism is determined by the hair covering thickness, and the two are in a proportional relationship. The greater the hair covering thickness, the larger the spreading angle of the comb claw mechanism, so that the comb claw mechanism can comb all the hair outside the scalp.

[0129] Step S302: Controlling the combing claw mechanism to unfold according to the unfolding angle to comb the hair when blowing, and obtaining the combing resistance of the combing claw mechanism.

[0130] The hair combing resistance refers to the resistance encountered by the combing claw mechanism when combing hair. The hair combing mechanism is provided with a pressure sensor, and the hair combing resistance can be obtained through the pressure sensor.

[0131] Step S303: If the combing resistance is greater than a preset reference resistance, it is defined as a hair knot, and a corresponding force-bearing claw is determined according to the combing resistance.

[0132] The reference resistance is a reference value of resistance set by technicians when the combing claw mechanism combs normal unknotted hair, which will not be described in detail here. When the combing resistance is not greater than the reference resistance, it means that the user's hair is unknotted. When the combing resistance is greater than the reference resistance, it means that the user's hair is unknotted, so that the combing claw resistance of the combing claw mechanism increases.

[0133] In this embodiment, the comb claw mechanism is composed of a plurality of comb claws arranged at intervals, and the distance between the comb claws is adjustable. The force-bearing claw refers to the comb claw that is hindered by the comb claw resistance formed by the tangled hair. The comb claw resistance of each comb claw on the comb claw mechanism is different, and it can be determined which comb claw is hindered by the tangled hair according to the comb claw resistance.

[0134] Step S304: adjusting the distance between the force-bearing claw and the adjacent force-bearing claw according to the preset spreading distance to separate the tangled hair.

[0135] The spreading distance is the distance between adjacent combing claws set by the technician to spread out tangled hair.

[0136] When the user uses the hair dryer to blow dry hair, if the combing claw mechanism encounters tangled hair, the system can control the force-bearing claws at the corresponding positions to expand at an expansion distance, so that the tangled hair is stretched out.

[0137] The user's hair may have dandruff characteristics, and the hair dryer can treat the dandruff characteristics. The method for treating the dandruff characteristics includes the following steps:

[0138] Step S400: determining the dandruff position and dandruff position type according to the head image information and the preset dandruff features, wherein the dandruff position types include attached to the hair and attached to the shoulder.

[0139] The dandruff position refers to the position of the dandruff feature on the user's head. By analyzing the head image information and the dandruff feature in the image recognition analysis method, the dandruff position of the dandruff feature on the user's head can be determined. There are two possible positions for dandruff, one is attached to the hair, and the other is attached to the shoulder or falls on the shoulder when blow-dried. The system uses different methods to handle the two types of dandruff position types.

[0140] Step S401: Based on the attachment to the hair, the hair layer depth where the dandruff feature is located is determined according to the head image information and the dandruff position.

[0141] Dandruff attached to the hair is not necessarily on the surface of the hair, but may be sandwiched between the hair. The depth of the hair layer refers to the depth distance from the location where the dandruff characteristics are sandwiched between the hair and the hair surface.

[0142] In this embodiment, only the dandruff features that can be seen from the hair surface are processed. The head image information and the dandruff position are analyzed by image recognition analysis to determine the hair layer depth of the dandruff features in the hair.

[0143] Step S402: matching the opening and closing area of ​​the dust suction hole preset in the blowing part 211 with the corresponding hair layer depth.

[0144] In this embodiment, the hair dryer is provided with a dust suction hole on the surface of the blowing part 211, and the dust suction hole is used to suck and remove the dandruff on the hair. The size of the dust suction hole can be controlled by the system to control the suction force. After the dandruff is sucked in through the dust suction hole, it can be opened from one side of the hair dryer to clean the dandruff.

[0145] The opening and closing area refers to the size of the area that the suction hole opens when removing the dandruff feature. The opening and closing area is proportional to the depth of the hair layer where the dandruff feature is located. The deeper the hair layer, the larger the opening and closing area required by the suction hole, and the greater the suction force required by the suction hole to remove the dandruff feature.

[0146] Step S403: When the hair dryer 2 is blowing and combing hair and the blowing part 211 moves to the dandruff position, the dust suction hole is controlled to open according to the opening and closing area to remove the dandruff characteristics.

[0147] When the user uses a hair dryer to blow dry hair, if the system detects a hair feature, it will mark the feature. When the hair dryer moves to the dandruff position, the system controls the dust suction hole to open and suck in and remove the dandruff feature.

[0148] Step S404: Based on the attachment to the shoulder, when the hair dryer head 2 moves to the dandruff position, the one-way air hole is controlled to open to drive the air inlet hole to remove the dandruff characteristics.

[0149] For the dandruff features attached to the shoulders, the system will mark the dandruff features at the shoulder position. When the hair dryer moves to the shoulder position, the system controls the one-way air holes to open. At this time, the air inlet holes can suck in and remove the dandruff features at the shoulder position.

[0150] If the user has broken hair, the broken hair will enter the hair dryer through the air inlet. At this time, the broken hair entering the hair dryer needs to be processed. The method for processing the broken hair includes the following steps:

[0151] In this embodiment, a rubber cylinder is rotatably arranged at a position corresponding to the air inlet in the inner cavity of the hair dryer and driven by a micro motor. The surface of the rubber cylinder is sticky and can absorb broken hair and dandruff sucked from the air inlet.

[0152] Step S500: obtaining surface image information of a rubber tube for collecting loose hair that is preset in the hair dryer head 2 .

[0153] The surface image information refers to the image of the surface of the rubber cylinder obtained by a micro camera arranged in the inner cavity of the hair dryer, and the surface of the rubber cylinder refers to the projection surface corresponding to the air duct hole.

[0154] Step S501: determining the area ratio of the broken hair features in the surface image information according to the surface image information and the preset broken hair features.

[0155] The area ratio refers to the area ratio of the position on the surface of the rubber cartridge where the hair is attached to the blank position, where the blank position is the position on the rubber cartridge that has not been used. By analyzing the surface image information and the hair features through image recognition analysis, the area ratio of the two can be determined.

[0156] Step S502: Based on the area ratio being greater than a preset ratio, determining according to the surface image information the rotation angle required to rotate the surface of the rubber cartridge without the hair fragments adhered thereto to face the air duct hole.

[0157] The preset percentage is a reference value set by the technicians to measure whether the rubber cylinder needs to be rotated and adjusted, which will not be elaborated here. When the area percentage is not greater than the percentage, it means that there are fewer hair fragments adhering to the surface of the rubber cylinder, and the hair fragments can continue to adhere to the surface. At this time, the rubber cylinder does not need to be adjusted. When the area percentage is greater than the percentage, the surface of the rubber cylinder facing the air duct can no longer adhere to the hair fragments, and the rubber cylinder needs to be rotated so that the new blank unused rubber cylinder surface is rotated to face the air duct.

[0158] The rotation angle refers to the angle required to rotate the surface of the rubber cylinder until the blank area is directly opposite to the air inlet. The rotation angle can be obtained by analyzing the surface image information through image recognition analysis.

[0159] Step S503: matching the air guide blades preset on the rubber cylinder according to the rotation angle.

[0160] In this embodiment, the rubber cartridge is provided with wind guide blades for circumferential rotation, and the wind guide blades can drive the rubber cartridge to rotate under the drive of wind entering the air inlet. The guide blades at different positions on the rubber cartridge can cause the rubber cartridge to rotate at different angles under the drive of wind, so the wind guide blades that need to be controlled can be determined according to the rotation angle obtained in step S502, so that the rubber cartridge rotates at a specific rotation angle.

[0161] Step S504: controlling the air guide blades to unfold according to a preset unfolding area so that the rubber cartridge rotates under the impact of wind and places the surface of the rubber cartridge without the broken hair adhering to the air inlet.

[0162] The unfolded area is a reference value of the area when the air guide blades are unfolded, which is set by the technicians. When the air guide blades are unfolded with the unfolded area, the rubber cylinder can be driven to rotate by the wind.

[0163] By controlling the specific air guide blades to expand, the air guide blades are driven by the wind to rotate the rubber cylinder to a specific rotation angle, so that the blank position of the rubber cylinder is directly opposite to the air inlet. When the rubber cylinder is rotated to the right position, the air guide blades retract, so that the rubber cylinder stops rotating.

[0164] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
