example one
As shown in fig. 1, the present embodiment provides a hair dryer including a blow cylinder 100, a handle 200 connected to the blow cylinder 100, and a power cord 400 connected to the handle 200. The main air duct is formed in the air blowing tube 100, the heating assembly 123 is arranged in the main air duct, the air blowing tube 100 is provided with the air inlet 101 and the air outlet 102 which are communicated with the main air duct, air flow enters the main air duct from the air inlet 101 at the rear side of the air blowing tube 100, and is discharged from the air outlet 102 after being heated by the heating assembly 123, so that the aims of drying and shaping of the hair dryer are fulfilled.
as shown in fig. 2, the blow cylinder 100 includes a housing 11, and left and right ends of the housing 11 are open for air flow to enter and blow out. The bottom of the housing 11 is provided with a mounting port 103, and the handle 200 is connected to the air blowing cylinder 100 through the mounting port 103.
As shown in fig. 3 and 4, a heating chamber 12 is disposed in the main air duct near the air outlet 102, and a heating assembly 123 is disposed in the heating chamber 12, and the heating assembly 123 is used for heating the air flow in the main air duct. In this embodiment, the heating chamber 12 is disposed near the air outlet 102, and the air heated by the heating element 123 is directly discharged from the air blowing tube 100, so as to reduce the loss of heat in the main air duct, and reduce the energy consumption of the hair dryer on the basis of meeting the air outlet temperature.
The blower also includes a blower assembly 13 for creating a negative pressure in the main duct so that air from outside the blower can enter the main duct under pressure. As shown in fig. 4, the blower assembly 13 includes a blower and an electronic control PCB 14, and the electronic control PCB 14 is connected to the blower and is used for controlling the blower to start and stop. The blower may include a motor and a fan, the motor driving the fan to rotate. Alternatively, the motor may be a brushless motor.
Among the prior art, for reducing the size of a section of thick bamboo 100 of blowing, set up blast air subassembly 13 and automatically controlled PCB board 14 in the handle, because brushless motor self size and the size of the automatically controlled PCB board 14 that needs the collocation are all great, lead to the length and the diameter of handle all great, no matter daily use or go out to carry inconvenient, influence the user and use experience.
To solve the above problem, as shown in fig. 4, in the present embodiment, the blowing assembly 13 is disposed in the blowing cylinder 100, and the air flow passes through the blowing assembly 13 and the heating chamber 12 in sequence in the air duct. Alternatively, the heating chamber 12 and the blower assembly 13 may communicate through the wind scoops 15. In the embodiment, the blowing assembly 13 is positioned in the blowing tube 100 to reduce the size of the handle, so that the user can feel better and the blowing device is convenient to use and carry.
in order to solve the problem that the brushless motor needs to be collocated with the electronic control PCB board 14, the electronic control PCB board 14 is of an annular structure in the embodiment, and is sleeved outside the blower assembly 13. The electric control PCB board 14 is arranged to be annular, so that the space occupied by the electric control PCB board 14 can be reduced; the electronic control PCB board 14 is sleeved outside the blowing component 13, so that the structure in the blowing cylinder 100 is more compact, and the size of the blowing cylinder 100 is reduced. Optionally, the electronic control PCB board 14 may be divided into two annular control boards, the radial size of the air blowing cylinder 100 that needs to be occupied by the electronic control PCB board 14 is reduced, and the two annular control boards may be connected through a connecting rib, so that the structure of the air blowing cylinder 100 is more compact.
Specifically, as shown in fig. 4 and 5, the blower assembly 13 includes a blower, a mounting sleeve 18 is disposed in the blower tube 100, and the mounting sleeve 18 includes a tubular blower connecting portion 181 and an end cover 182 connected to an end of the blower connecting portion 181 close to the air inlet 101. The both ends opening of installation sleeve 18, the fan is located installation sleeve 18 to play the effect of protection fan. The annular electric control PCB board 14 is sleeved in the mounting sleeve 18, so that the direct contact between the fan and the electric control PCB board 14 is avoided. The end cap 182 is disposed at an end of the mounting sleeve 18 near the air inlet 101, and the end cap 182 is provided with a central hole communicating with the air inlet 101 of the air blowing cylinder 100. The interior of the blower forms a blast chamber which communicates with the heating chamber 12 to form a main air duct.
in this embodiment, the electronic control PCB 14 is sleeved outside the blower assembly 13, that is, the electronic control PCB 14 is located outside the main air duct, and the air flow does not contact with the electronic control PCB 14, so that noise of the electronic control PCB 14 in the main air duct can be prevented from increasing, turbulence caused by air flow disturbance can be prevented, and smoothness of air flow circulation in the main air duct can be improved.
Because automatically controlled PCB board 14 is located outside the main wind channel, and automatically controlled PCB board 14 can produce a large amount of heats at the during operation, for the heat that conveniently automatically controlled PCB board 14 produced spills, avoid section of thick bamboo 100 of blowing to generate heat, automatically controlled PCB board 14 still is connected with heat radiation structure, and heat radiation structure can derive the heat on the automatically controlled PCB board fast to solve the heat dissipation problem of automatically controlled PCB board 14 setting outside the main wind channel.
specifically, the heat dissipation structure includes a heat dissipation assembly, one end of which is in contact with the heating element on the electronic control PCB 14, and the other end of which extends into the main air duct, so that heat generated by the heating element is dissipated. The heat dissipation assembly may be in direct contact with the heating element or may be in indirect contact with the heating element through another structure as long as the heat dissipation assembly can conduct heat.
The heat dissipation assembly is in contact with the heating element, and heat on the heating element can be transferred to the heat dissipation assembly. At least part of the heat dissipation assembly is positioned in the main air duct, and the heat of the heat dissipation assembly is taken away by air flow with the temperature lower than that of the heat dissipation element, such as natural air, so that the heat dissipation effect of the heating element is achieved. Namely, the heat dissipation assembly is used as an auxiliary heat dissipation device of the heating element, so that heat on the heating element can be efficiently conducted away in time, normal operation of structures such as the electric control PCB (printed circuit board) 14 can be ensured, the service life of a product is prolonged, and the problem that the electric control PCB 14 cannot well dissipate heat in the existing blower is solved.
Specifically, as shown in fig. 5 and 6, the mounting sleeve 18 may further be provided with a first heat sink 191, one end of the first heat sink 191 is in contact with the heat generating element on the electronic control PCB 14, and the other end is located in the air inlet 101 of the air blowing cylinder 100. The heat generated by the heating element is transferred to the first heat sink 191 through heat conduction, and is transferred to one end of the air inlet 101 through the first heat sink 191, and the heat on the first heat sink 191 is taken away as the air flow enters the air inlet 101. In this embodiment, the air flow carrying away heat enters the heating chamber 12 through the blast chamber, and the heat generated by the heating element is utilized to avoid heat waste. Optionally, the heating element in this embodiment may be a MOS transistor or a thyristor on the electronic control PCB 14.
as shown in fig. 7, the first heat sink 191 includes a base 1911 and a plurality of fins 1912 provided on the base 1911, the fins 1912 being provided so as to extend from the heat generating element toward the air intake end. Preferably, the fins 1912 are inclined toward the incoming wind, so that the heat exchange area with the airflow is increased, the wind resistance is reduced as much as possible, and the noise is reduced. That is, the fins 1912 extend in a direction opposite to the direction of the blower inlet air, thereby allowing the fins 1912 to contact the further upstream, lower temperature air stream.
the fins 1912 include a bottom side distal from the wind inlet end, a top side proximal to the wind inlet end, a front side on the windward side, and a rear side on the leeward side. The bottom of the fin 1912 is arranged on the base 1911, so that the structure is more stable; the top is necessarily positioned in the main air duct, and whether other structures are positioned in the main air duct or not is determined according to actual use requirements. In this embodiment, the top of the fins 1912 is located within the air intake 101.
Along the air inlet direction, the distance between top and the bottom reduces gradually, and the top is along the inclined plane of air inlet direction slope promptly, reduces the windage under the radiating condition of not influencing, reduces the noise. The front side surface is convexly arched, namely, similar to a tile shape, air flow is more stable when air is blown through the front side surface, and noise is low. The junction of trailing flank and top is the cambered surface, promptly, trailing flank and the smooth transitional coupling in top avoid the air inlet to be hindered at the junction of trailing flank and top.
The base 1911 is provided with a step surface 1913, and the step surface 1913 is attached to the heating element, so that the heat conduction efficiency is high. At the same time, the step surface 1913 also serves as a limit for the base 1911 and the heating element.
The base 1911 may be formed in any shape, as long as it can efficiently conduct heat to the heating element. Preferably, the base 1911 is a fan-shaped sheet-like structure aligned with a heat generating spot on the heat generating component or an annular sheet-like structure aligned integrally with the heat generating component. When the ring-shaped radiator is annular, the radiating area is large, and the radiating efficiency is high; when the fan-shaped air blower is fan-shaped, the volume is small, the weight is light, and the miniaturization and the light weight of the air blower are facilitated. Preferably, the base 1911 is directly connected to the heat generating point of the heat generating component in a heat conducting manner, so that the heat conducting efficiency is higher.
The base 1911 can not only transmit heat to the portion attached to the heating element, but also rapidly guide away heat in the space around the heating element, and also has the function of assisting the heat dissipation of the heating element.
Optionally, in this embodiment, the electronic control PCB 14 is a double-layer annular structure, and the electrical components on the electronic control PCB 14 may be disposed on two annular surfaces outside the double-layer annular structure, wherein the electrical components on one side close to the air inlet 101 may dissipate heat through the first heat sink 191, and the heat dissipation component connected to the other side is far away from the air inlet 101, and is difficult to extend into the air inlet 101, so that the heat dissipation effect is poor.
In order to solve the above problem, in the present embodiment, as shown in fig. 8 and 9, the heat dissipation assembly further includes a second heat dissipation plate 192, and the second heat dissipation plate 192 is located on a side of the electronic control PCB 14 away from the air inlet. One end of the second heat sink 192 contacts with the heating element on the side of the electronic control PCB 14, and the other end can extend into the heating chamber 12, so as to take away heat by the airflow entering the heating chamber 12, thereby realizing heat dissipation. Specifically, the second heat dissipation fins 192 may penetrate through the heat conduction cover 15 and extend into the upstream of the heating chamber 12, i.e., the air guiding cover 15, the temperature of the side air flow is low, the heat dissipation efficiency may be improved, and the heat on the second heat dissipation fins 192 is used for heating the air flow, so as to improve the heat utilization rate.
In order to reduce the gap between the second heat sink 192 and the wind scooper 15, a wind blocking plug is further disposed between the second heat sink 192 and the wind scooper 15, and the wind blocking plug can prevent the gas in the heating chamber 12 from entering between the housing 11 and the main duct.
on the basis of the structure, the heat conducting materials are filled in the gap between the heat dissipation assembly and the heating element, so that the heat dissipation assembly is reliably connected with the heating element in a heat conducting manner, and the problem that heat on the heating element cannot be transferred to the heat dissipation assembly due to the isolation of air is avoided. The heat conducting material can be, but is not limited to, heat conducting silicone grease, and the heat can be efficiently transferred.
In other embodiments, the heat dissipation structure may also be an air guiding cover 15, and specifically, the air guiding cover 15 connecting the blower assembly 13 and the heating chamber 12 may be provided with a flow guiding structure, and the flow guiding structure may guide a portion of the air flow entering from the air inlet 101 to the electronic control PCB 14, so as to improve the heat dissipation effect of the electronic control PCB 14. Specifically, the wind scooper 15 is connected to the mounting sleeve 18 of the blower unit 13 at one end and to the heating chamber 12 at the other end. The air guiding cover 15 is provided with a first diversion hole, the end cover 182 of the air blowing component 13 is provided with a second diversion hole, part of air flow passing through the air guiding cover 15 enters between the shell 11 and the air blowing component 13 through the first diversion hole to cool the electronic control PCB 14, and the air flow absorbing heat of the electronic control PCB 14 flows out of the second diversion hole, so that a circulation air path for cooling the electronic control PCB 14 is formed.
In order to avoid the hair from being dry and easy to generate static electricity after the hair dryer is used, the hair dryer can further comprise a negative ion generator 23, the negative ion generator 23 can generate air negative ions, the air negative ions are contacted with the hair along with air flow, static electricity generated by the hair is avoided, and therefore the hair is more flexible, and the purpose of hair maintenance is achieved. However, in the conventional hair dryer, the negative ion generator 23 is located in the air blowing cylinder 100, for example, on the outer peripheral surface of the heating chamber 12, and occupies a space of the air blowing cylinder 100, so that a gap between the heating chamber 12 and the housing 11 is large, resulting in a large size of the air blowing cylinder 100.
In order to solve the above problem, in the present embodiment, as shown in fig. 10 to 12, the negative ion generator 23 is disposed in the handle 200, and the discharge end 231 of the negative ion generator 23 extends into the air blowing cylinder 100. By disposing the negative ion generator 23 in the handle 200, the size of the blower pipe 100 can be reduced, which is advantageous for reducing the size between the heating chamber 12 and the housing 11, making the structure of the blower pipe 100 more compact, which is advantageous for reducing the size of the blower pipe 100.
Since the time of the negative ions existing in the air is short, in order to shorten the time of the negative ions generated by the discharge end 231 in the main air duct, the discharge end 231 may extend toward the air outlet 102 of the air blowing cylinder 100, so that the negative ions can contact the hair as soon as possible.
Alternatively, the discharge end 231 may be located on the central axis of the blow cylinder 100, which may further improve the space utilization within the blow cylinder 100 on the one hand, and may also make the negative ions more uniformly distributed on the other hand.
specifically, the heating chamber 12 includes an outer cylinder 121 and an inner cylinder 122. The downstream end of the outer cylinder 121 is provided with an ion outlet 1211 and an air outlet 102. The inner tube 122 is open at both ends and disposed in the outer tube 121, a heating element 123 is disposed between the inner tube 122 and the outer tube 121, and the discharge end 231 is disposed in the inner tube 122 and faces the ion outlet 1211. The air current enters between the inner cylinder 122 and the outer cylinder 121 after passing through the blast chamber, the discharge end 231 works to generate negative ions while the temperature is raised under the action of the heating component 123, and the negative ions are discharged from the ion outlet 1211 and mixed into the air current to be in contact with hairs to eliminate static electricity.
In order to protect the discharge end 231, an ion end cap 232 is further disposed outside the discharge end 231 to prevent components in the heating chamber 12 from contacting the discharge end 231, so as to protect the discharge end 231.
Alternatively, the heating assembly 123 includes a plurality of heating units, each of which extends along the axial direction of the inner cylinder 122, and the plurality of heating units are uniformly distributed along the circumferential direction of the inner cylinder 122, so as to improve the uniformity of heating. In order to avoid heat dissipation through the outer cylinder 121, the heating assembly 123 further includes a heat insulation cylinder 1232 disposed inside the outer cylinder 121, and the heat insulation cylinder 1232 can reduce heat loss and improve heat utilization rate.
As shown in fig. 12, in order to facilitate the user to use the hair dryer, the handle 200 is further provided with control buttons 26 such as a switch button, a wind speed adjusting button, a wind temperature adjusting button, and a mode adjusting button, so as to control the start and stop of the hair dryer, the wind speed, the wind temperature, or select a proper blowing mode. In order to control the blower by the above buttons, a main control PCB board 24 is further disposed in the handle 200, and the main control PCB board 24 is connected to the blowing assembly 13, the heating assembly 123 and the negative ion generator 23, respectively, so as to control the blowing assembly 13 and the heating assembly 123 according to the operation of the user. Alternatively, the negative ion generator 23 may be disposed at the bottom of the main control PCB board 24.
Optionally, the hair dryer may further comprise a plurality of nozzles, each of which is detachably connected to the outlet 102 of the barrel 100, so as to be replaced according to different use requirements of users. Alternatively, the air nozzle may be connected to the air blowing cylinder 100 by a snap structure, by magnetic attraction, or by a fastener such as a screw.
in the prior art, a blower having a blower built into the handle 200, such as a Darsen Supersonic HD01 type blower, can reduce the size of the barrel 100, the diameter and length of the barrel 100 being 78mm and 97mm, respectively, but the handle 200 is lengthened and the length of the handle 200 is 245 mm. In this embodiment, by adjusting the structure and position of each component in the hair dryer, the size of the barrel 100 can be reduced, such that the length of the barrel 100 is not more than 125mm, for example, less than 120mm, the diameter of the barrel 100 is not more than 80mm, for example, less than 77mm, the size of the barrel 100 can be slightly different from the size of the barrel 100 in the dyson supersonics HD01 hair dryer, and the main air duct does not need to pass through the handle 200, so that the length of the main air duct is greatly shortened, and the efficiency of the hair dryer is significantly improved. By reasonably arranging the components in the air blowing tube 100, the volume of the handle 200 does not need to be increased, the length of the handle 200 can be not more than 125mm, the diameter of the handle 200 can be not more than 40mm, for example, the length of the handle 200 can be shortened to 170mm, the diameter of the handle can be shortened to 38mm, and compared with 245mm in the prior art, the length of the handle 200 is greatly shortened.
Example two
This embodiment provides a hair dryer which is different from the first embodiment in that a protection device is further provided in the hair dryer so as to prevent the hair dryer from being overheated. The protection device comprises a temperature detection member 17. As shown in fig. 4, the temperature detecting member 17 may be provided inside the heating chamber 12. Specifically, the temperature detector 17 is disposed on the outer peripheral surface of the inner cylinder 122, and the main control PCB 24 receives a signal transmitted by the temperature detector 17 and controls the heating element 123 to be intermittently turned off according to a temperature value obtained by the temperature detector 17.
Specifically, the main control PCB board 24 includes a storage unit, a comparison unit and an execution unit, the storage unit is used for prestoring a first temperature preset value and a second temperature preset value, and the comparison unit is used for comparing the temperature value obtained by the temperature detection member 17 with the first temperature preset value and the second temperature preset value. The execution unit is configured to judge that the temperature value obtained by the temperature detection part 17 is overheated if the temperature value is higher than a first temperature preset value when the blower works in the drying mode, and the main control PCB 24 controls the heating component 123 to be closed to stop heating and the blower component 13 of the blower to normally operate; when the blower is in the drying mode and the heating assembly 123 is in the stop state, if the temperature value obtained by the temperature detecting part 17 is lower than the second temperature preset value, the main control PCB 24 controls the heating assembly 123 to be turned on again.
When the temperature value obtained by the temperature detecting member 17 is between the second temperature preset value and the first temperature preset value, it indicates that the temperature of the heating assembly 123 is normal. The first temperature preset value and the second temperature preset value are not limited and can be set according to actual conditions.
In use, with the hair dryer in a drying mode, the blower assembly 13 and the heating assembly 123 are activated simultaneously to provide hot air. In the using process, the temperature detecting part 17 can detect the temperature of the heating component 123 in real time and transmit the obtained signal to the main control PCB board 24, the main control PCB board 24 obtains the current temperature value of the heating component 123 and compares the current temperature value with the first temperature preset value and the second temperature preset value, and if the current temperature value is between the second temperature preset value and the first temperature preset value, it indicates that the temperature of the heating component 123 is normal.
After the blower is used for a period of time, when the temperature value of the heating component 123 is higher than the first temperature preset value, the overheating is indicated, the main control PCB board 24 controls the heating component 123 to be closed and stop heating, so that the situation that parts of the blower are burnt or a user is scalded due to the overhigh temperature in the blower is avoided, at the moment, the blower component 13 still runs normally, and the residual temperature of the heating component 123 can also ensure that hot air is generated. The air blowing component 13 can cool the heating component 123, and meanwhile, during the heating of the heating component 123 is stopped, the residual temperature of the heating component 123 can also ensure that hot air is generated, so that the normal use is not influenced; when the temperature of the component 123 to be heated is reduced to be lower than the second preset temperature value, the main control PCB 24 controls the heating component 123 to be turned on again. Intermittent turn-on is beneficial to cooling down the heating element 123 and does not affect normal use.
The main control PCB 24 is connected with the heating component 123 through a heating regulation and control circuit, a controllable silicon is arranged on the heating regulation and control circuit, and the main control PCB 24 controls the controllable silicon to be turned on and off. When the thyristor is turned off, the power supply unit of the heating unit 123 is turned off, and the heating unit 123 is turned off to stop heating, but the blower unit 13 is normally operated.
EXAMPLE III
The present embodiment provides a hair dryer, which is different from the second embodiment in that the main control PCB 24 is electrically connected to the blowing assembly 13 and an auxiliary temperature detecting member capable of detecting the temperature near the blowing assembly 13, and the main control PCB 24 controls the on/off of the main power supply unit according to the temperature value obtained by the auxiliary temperature detecting member.
If the temperature of the blower assembly 13 is too high, which indicates that the blower assembly 13 is working for too long or working abnormally, the main control PCB 24 immediately turns off the power supply unit of the blower assembly 13, and the blower assembly 13 stops working, and the heating assembly 123 works alone without passing cold air, which would cause overheating, so that the power supply of the heating assembly 123 needs to be cut off at the same time. Therefore, when the temperature of the blower assembly 13 is too high, the main control PCB 24 needs to cut off the power of the blower assembly 13 and the heating assembly 123, i.e., turn off the total power supply unit.
The blower assembly 13 is connected in parallel with the heating assembly 123 for independent control. The temperature detecting member 17 and the auxiliary temperature detecting member are connected in parallel to prevent mutual interference between detection results.
A third temperature preset value is prestored in the storage unit of the main control PCB 24, and when the temperature value obtained by the auxiliary temperature detection part is higher than the third temperature preset value, it indicates that the temperature of the blower assembly 13 is too high, and then the main control PCB 24 closes the main power supply unit. Here, the third temperature preset value is not limited, and may be set according to actual conditions.
At this time, the operator may turn on the main switch to detect the overheating caused by the long-term operation of the blower assembly 13 or the overheating caused by the failure of the blower assembly 13 after the blower stands for a certain period of time to cool down. If the air is not blown out when the air is opened again, the air blowing assembly 13 is in failure, so that the maintenance is convenient to be carried out in time; if the air is normally exhausted when the air conditioner is opened again, the time for using the air blowing assembly 13 for the last time is too long.
The temperature detection piece 17 and the auxiliary temperature detection piece are arranged in a matched mode, double protection is achieved for the hair dryer, and the fact that detection caused by one fault is inaccurate is prevented.
Example four
The present embodiment provides a hair dryer, which is different from the second embodiment in that a wind speed sensor is disposed at the air outlet 102 of the hair dryer, and the wind speed sensor is electrically connected to the main control PCB 24. The wind speed sensor is used for detecting the wind speed of the air outlet 102, and the wind speed sensor is matched with the temperature detection piece to protect the blower in multiple ways.
When the temperature detecting member 17 detects that the temperature of the heating assembly 123 is too high while the hair dryer is in the drying mode, in addition to the possibility that the heating assembly 123 is operated for too long, the air blowing assembly 13 may be stopped or the air outlet may be blocked. At this time, the main control PCB 24 controls the heating element 123 to close and stop heating, and performs comprehensive judgment according to the wind speed value detected by the wind speed sensor.
if the wind speed value obtained by the wind speed sensor is lower than the wind speed preset value, indicating that the blowing assembly 13 is in fault and stops rotating, the main control PCB 24 can close the blowing assembly 13 at the same time of closing the heating assembly 123, namely close the main power supply unit, and maintain the blowing assembly 13. At this time, if the wind speed value obtained by the wind speed sensor is normal, which indicates that the blowing component 13 is normal, the main control PCB 24 may only close the heating component 123, and the blowing component 13 is utilized to dissipate heat from the heating component 123, and simultaneously inspect and process the air outlet.
Therefore, the setting of the wind speed sensor can further determine the state of the blower, and further adopt a better processing mode. Here, the preset value of the wind speed pre-stored in the main control PCB 24 is not limited, and can be set according to actual conditions.
if the main control PCB board 24 judges that the blower has a fault, the alarm lamps with different colors can prompt according to the different types of the faults, so that the targeted maintenance of a user is facilitated.
EXAMPLE five
The present embodiment provides a hair dryer, which is different from the second embodiment in that a motor is provided with a rotation speed sensor, and the rotation speed sensor is electrically connected with the main control PCB 24. The rotating speed sensor is used for detecting the rotating speed of the motor, and the rotating speed sensor is matched with the temperature detection piece to protect the blower in multiple ways.
When the temperature detecting member 17 detects that the temperature of the heating assembly 123 is too high while the hair dryer is in the drying mode, in addition to the possibility that the heating assembly 123 is operated for too long, the air blowing assembly 13 may be stopped or the air outlet may be blocked. At this time, the main control PCB 24 controls the heating element 123 to be turned off and stop heating, and performs comprehensive judgment according to the rotation speed value detected by the rotation speed sensor.
If the rotating speed of the air blowing component 13 is within the preset rotating speed range, it indicates that the air outlet is possibly blocked, at this time, only the heating component 123 is turned off, the air blowing component 13 is utilized to dissipate heat of the heating component 123, and meanwhile, the air outlet is inspected and processed. If the blower is provided with the heat dissipation device, the heat dissipation device can be opened to dissipate heat. Or, the blower is placed still for heat dissipation. After the blower is cooled, it can be reused. If the rotating speed of the blower assembly 13 is abnormal, it indicates that the blower assembly 13 is in a fault and stops rotating, and at this time, the main control PCB board 24 can turn off the blower assembly 13 while turning off the heating assembly 123, that is, turn off the main power supply unit, and maintain the blower assembly 13.
a preset rotating speed range is prestored in the storage unit of the main control PCB 24, the rotating speed value detected by the rotating speed sensor is compared with two end point values in the preset rotating speed range, and if the rotating speed value is not in the preset rotating speed range, it indicates that the rotating speed of the blower assembly 13 is abnormal.
If the temperature value obtained by the temperature detector 17 is lower than the second preset temperature value, at this time, before the heating element 123 is controlled to be turned on, it is ensured that the rotation speed value obtained by the rotation speed sensor is within the preset rotation speed range, which indicates that the blower element 13 is in the normal operation state, and then the heating element 123 is controlled to be turned on, so as to ensure the safety.
therefore, the arrangement of the rotating speed sensor can further determine the state of the blower, and further adopt a better processing mode.

in addition, because the pores of the filtering sponge or the filtering net are smaller, the filtering sponge or the filtering net can filter dust and fine hair with smaller diameter, the dust and the fine hair with smaller diameter can be prevented from entering the air channel of the air blowing cylinder 100, and the user experience is improved. Preferably, the pore density (PPI) of the filter sponge is not less than 40PPI, and the mesh number of the filter net is not less than 40, so that a good filtering effect of the filter assembly 1123 on foreign matters such as dust and hair can be ensured, and the filter assembly 1123 does not reduce the intake of the blower.
