[0027] The utility model provides an intelligent hair dryer.

[0028] In the embodiment of the present utility model, Figures 1 to 5 As shown, the smart hair dryer includes a shell 10, a circuit device and a detection device 20. The shell 10 has a front face 111, a rear face 112 opposite to the front face 111, and a through hole 114 extending from the rear face 112 to the front face 111. The front face 111 is provided with an air outlet 113, and a mounting portion 13 is provided in the through hole 114 and at one end close to the front face 111, and a ventilation gap 15 is formed between the mounting portion 13 and the wall of the through hole 114; the circuit device is arranged in the shell 10; the detection device 20 is arranged in the mounting portion 13 and is electrically connected to the circuit device. The detection device 20 is arranged toward the front of the front face 111 and is used to detect the state of an object (hair or clothing, etc.) in front of the air outlet 113 when in use.

[0029] Specifically, the intelligent hair dryer further includes a heating component 31 and a fan component 32, both of which are electrically connected to the circuit device. An air duct is further provided in the housing 10, and both of the heating component 31 and the fan component 32 are provided in the air duct. When the fan component 32 drives the airflow through the air duct, the airflow can be heated by the heating component 31, so that hot air is blown out of the air outlet 113. The through hole 114 is arranged to be through-through from front to back. When the airflow is blown out from the air outlet 113, it can drive the airflow in the through hole 114 to flow forward from the ventilation gap 15. In this way, the airflow passing through the ventilation gap 15 can be used to block the heat at the air outlet 113 and the heating component 31, thereby preventing the heat from being conducted to the detection device 20, and can also dissipate heat for the mounting portion 13 and the detection device 20.

[0030] The present invention provides a through hole 114 extending from the rear end face 112 to the front end face 111 on the housing 10, and provides a mounting portion 13 within the through hole 114 and at one end near the front end face 111, so that a ventilation gap 15 is formed between the mounting portion 13 and the wall of the through hole 114. The detection device 20 is then mounted on the mounting portion 13. Thus, when the smart hair dryer is in use, the airflow from the air outlet 113 drives the airflow in the through hole 114 forward through the ventilation gap 15, and the airflow through the ventilation gap 15 can be used to dissipate heat from the mounting portion 13 and the detection device 20. Furthermore, when the hot air function of the smart hair dryer is used, the airflow through the ventilation gap 15 can be used to prevent heat from being transferred to the mounting portion 13 and the detection device 20. This effectively prevents the detection device 20 from overheating during use and thus affecting the detection effect. This effectively reduces the interference of heat generated by other components of the smart hair dryer on the detection device during use, and thus improves the detection reliability of the detection device 20. Furthermore, disposing the detection device 20 in the through hole 114 near the front end surface 111 can reduce the shielding of the detection device 20 by the through hole 114 and improve detection reliability.

[0031] In some embodiments, the detection device 20 includes at least one of a distance sensor 21 and a temperature sensor 22, wherein the distance sensor 21 is used to detect the position state of the object in front of the air outlet 113 relative to the air outlet 113 when in use, and the temperature sensor 22 is used to detect the temperature state of the object in front of the air outlet 113 when in use.

[0032] Specifically, the circuit device includes a circuit board and a controller disposed on the circuit board, etc., to control the operating states of the fan assembly 32, the heating assembly 31, the temperature sensor 22, and the distance sensor 21 through the circuit device. For example, the circuit device controls the speed of the fan assembly 32 and the power level and start / stop of the heating assembly 31. The specific circuit structure of the circuit device can be referred to in the prior art, and the present invention will not elaborate on this one by one.

[0033] When the distance sensor 21 is provided, the distance between the object in front of the air outlet 113 and the air outlet 113 can be detected by the distance sensor 21, thereby obtaining the position state of the object relative to the air outlet 113. The controller adjusts the operating state of at least one of the heating component 31 and the fan component 32 according to the position state of the object relative to the air outlet 113. For example, when it is determined that the distance between the object in front of the air outlet 113 and the air outlet 113 is relatively close, the heating power of the heating component 31 is reduced, or the heating power of the heating component 31 and the motor speed of the fan component 32 are reduced simultaneously; or the heating component 31 is controlled to stop working. When it is determined that the distance between the object in front of the air outlet 113 and the air outlet 113 is relatively far, the heating power of the heating component 31 and / or the motor speed of the fan component 32 are increased.

[0034] Similarly, when a temperature sensor 22 is provided, the surface temperature of the object in front of the air outlet 113 can be detected by the temperature sensor 22, thereby obtaining the temperature state of the object. The controller then adjusts the operating state of at least one of the heating component 31 and the fan component 32 based on the temperature state of the object. For example, when it is determined that the surface temperature of the object in front of the air outlet 113 is higher than a high temperature threshold, the heating power of the heating component 31 is reduced, or both the heating power of the heating component 31 and the motor speed of the fan component 32 are reduced; or the heating component 31 is controlled to stop operating. When it is determined that the surface temperature of the object in front of the air outlet 113 is lower than a low temperature threshold, the heating power of the heating component 31 is increased and / or the motor speed of the fan component 32 is increased.

[0035] The detection device 20 is arranged in a position close to the front end surface 111 in the through hole 114, so that the detection device 20 is closer to the air outlet 113, which can reduce the difference between the distance from the distance sensor 21 to the object and the distance from the air outlet 113 to the object, and improve the detection reliability of the distance sensor 21.

[0036] The distance sensor 21 includes one or more of a laser ranging sensor, an infrared ranging sensor or a radar ranging sensor; the temperature sensor 22 may be an ultrasonic temperature sensor 22 , a laser temperature sensor 22 or an infrared temperature sensor 22 .

[0037] In some embodiments, when the mounting portion 13 is provided with the distance sensor 21 and the temperature sensor 22, the distance sensor 21 and the temperature sensor 22 are distributed vertically. By distributing the distance sensor 21 and the temperature sensor 22 vertically, it is beneficial to improve detection reliability.

[0038] In some embodiments, the mounting portion 13 is provided with a plurality (at least two) of connecting portions 14 at intervals along the circumference of the mounting portion 13. The connecting portions 14 are connected to the walls of the through-hole 114, and a ventilation gap 15 is formed between any two adjacent connecting portions 14. The plurality of ventilation gaps 15 surround the mounting portion 13, so that when the smart hair dryer is in use, an annular airflow can be formed around the mounting portion 13, which can better prevent heat from being transferred to the mounting portion 13 and the detection device 20.

[0039] Optionally, one or more of the connecting portions 14 is provided with a wire groove 141 , and the connecting wires between the detection device 20 and the circuit device are arranged in the wire groove 141 .

[0040] In some embodiments, the connecting portion 14 is spaced apart from the front face 111, and the mounting portion 13 extends forward from the connecting portion 14. This allows the connecting portion 14 to be as far away from the air outlet 113 as possible, reducing the effect of the connecting portion 14 on separating the annular airflow within the through hole 114, while ensuring that the mounting portion 13 is close to the air outlet 113.

[0041] In some embodiments, a mounting groove 131 is provided on the front side of the mounting portion 13, and the detection device 20 is provided in the mounting groove 131. The smart hair dryer also includes a cover plate 40 covering the mounting groove 131. The cover plate 40 has a penetration portion at a position corresponding to the detection device 20, and the penetration portion is used to allow the signal emitted by the detection device 20 to pass through. That is, the cover plate 40 can be formed separately. During assembly, the detection device 20 is first installed in the mounting groove 131, and then the cover plate 40 covers the mounting groove 131. This can simplify the structure of the mounting portion 13 and facilitate molding. Among them, a through hole can be provided on the cover plate 40 at a position corresponding to the detection device 20 to form a penetration portion for the signal emitted by the distance sensor 21 and / or the temperature sensor 22 to pass through; or the cover plate 40 as a whole or at a position corresponding to the detection device 20 can be made of a transparent material to form a penetration portion for the signal emitted by the distance sensor 21 and / or the temperature sensor 22 to pass through.

[0042] In some embodiments, the housing 10 includes a handheld portion 12 and an air outlet portion 11 connected to one end of the handheld portion 12, an air outlet 113 and a through hole 114 are provided on the air outlet portion 11, and the handheld portion 12 is provided with an air inlet duct 121, which is connected to the air outlet 113. That is, the handle can be used to form the air inlet duct 121, which can not only ensure the normal setting of the air duct, but also reduce the impact of the setting of the through hole 114 on the air duct. Optionally, the heating component 31 is provided in the air guide duct 115, and the fan component 32 is provided in the air inlet duct 121, so that the heating component 31 is closer to the air outlet 113, which can reduce the loss of hot air flow before it is blown out from the air outlet 113, and using the handle to install the fan component 32 can reduce the size of the air outlet 11, which is conducive to reducing the overall size of the smart hair dryer. Moreover, even if the heating component 31 is placed close to the air outlet 113 , the arrangement of the through hole 114 and the ventilation gap 15 can effectively reduce the interference of the heat generated by the heating component 31 on the detection device 20 during use.

[0043] In some embodiments, the air outlet portion 11 is provided with an air guide duct 115, which is arranged around the through hole 114 and communicates with the air inlet duct 121. The front face 111 is provided with a plurality of air outlets 113, which are arranged around the through hole 114 and communicate with the air guide duct 115. This ensures a better air outlet effect and reduces the impact of the through hole 114 and the mounting portion 13 on the air outlet effect.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
