[0038] The utility model provides an intelligent hair dryer.

[0039] In the embodiment of the present utility model, Figures 1 to 7 As shown, the smart hair dryer includes a shell component 10, a circuit component 40 and a distance sensor 51. The shell component 10 is provided with an air inlet 101, an air outlet 102 and an air duct 103 formed between the air inlet 101 and the air outlet 102. The air outlet 102 is located at one end of the shell component 10. A fan component 20 and a heating component 30 are provided in the air duct 103.

[0040] The circuit assembly 40 is disposed on the housing assembly 10 and connected to the fan assembly 20 and the heating assembly 30; the distance sensor 51 is disposed on one end of the housing assembly 10 where the air outlet 102 is located, and the circuit assembly 40 is electrically connected to the distance sensor 51, so as to adjust the working state of at least one of the fan assembly 20 and the heating assembly 30 according to the distance signal measured by the distance sensor 51 in the intelligent mode;

[0041] Specifically, one end of the air duct 103 is connected to the air inlet 101 , and the other end is connected to the air outlet 102 . The hair dryer can drive the external air flow into the air duct 103 from the air inlet 101 , and blow it out from the air outlet 102 after passing through the heating component 30 .

[0042] The circuit assembly 40 includes a circuit board and a control circuit disposed on the circuit board, etc., so as to control the working states of the fan assembly 20, the heating assembly 30 and the distance sensor 51 through the circuit assembly 40. For example, the power size and start and stop of the fan assembly 20 and the heating assembly 30 are controlled, and the start and stop of the distance sensor 51 are controlled. The specific circuit structure of the circuit assembly 40 can refer to the prior art, and the utility model will not repeat them one by one.

[0043] The distance sensor 51 and the air outlet 102 are located at the same end of the shell assembly 10. When in use, the air outlet 102 and the distance sensor 51 can be simultaneously directed toward the blown object (a person or an object). At this time, the distance signal between the distance sensor 51 and the blown object can be measured, that is, the distance between the air outlet 102 and the blown object can be measured.

[0044] The distance sensor 51 transmits the distance signal to the analog-to-digital converter of the circuit component 40, and the analog-to-digital converter performs analog-to-digital conversion to form digital information. The analog-to-digital converter transmits the digital information to the main control circuit of the circuit component 40, and the main control circuit determines the distance information according to the digital information, and then adjusts the working state of at least one of the heating component 30 and the fan component 20 according to the distance information, that is, the power of the fan component 20 and the heating component 30 can be automatically adjusted according to the distance signal of the distance sensor 51, so that the wind temperature and air volume received by the blown object are kept within a reasonable range. For example, when it is determined that the distance between the air outlet 102 and the blown object is close (one or more distance thresholds can be preset for judgment, the same below), the heating power of the heating component 30 is reduced by the circuit component 40, or the heating power of the heating component 30 and the motor speed of the fan component 20 are reduced at the same time; or, the heating component 30 is controlled to stop working. When it is determined that the distance between the air outlet 102 and the blown object is far, the heating power of the heating component 30 and / or the motor speed of the fan component 20 are increased by the circuit component 40. The distance sensor 51 includes one or more of a laser distance sensor, an infrared distance sensor or a radar distance sensor.

[0045] By setting a distance sensor 51 at the end where the air outlet 102 is located, the distance sensor 51 can be used to detect the distance between the air outlet 102 and the blown object, and then the circuit component 40 controls the working state of the heating component 30 and the fan component 20 according to the distance signal measured by the distance sensor 51, thereby achieving real-time adjustment of the working state of the heating component 30 and the fan component 20 according to the change of the distance between the air outlet 102 and the blown object, so that the wind temperature and air volume received by the blown object are maintained within a reasonable range, thereby improving the intelligent effect of the smart hair dryer and improving the comfort and safety of users.

[0046] In some embodiments, the smart hair dryer has a smart mode and a manual mode, and the circuit component 40 is electrically connected to the distance sensor 51 to adjust the working state of at least one of the fan component 20 and the heating component 30 according to the distance signal measured by the distance sensor 51 in the smart mode.

[0047] The smart hair dryer also includes a status indicator light 53, which is disposed at one end of the housing assembly 10 where the air outlet 102 is located and is electrically connected to the circuit assembly 40. The status indicator light 53 is configured to be turned on in the smart mode and turned off in the manual mode.

[0048] Specifically, in the smart mode, the distance sensor 51 is in the on state, and in the manual mode, the distance sensor 51 is in the off state. That is, in the manual mode, the wind speed and temperature of the smart hair dryer are manually controlled by the user, and the wind speed and temperature of the smart hair dryer can be kept constant under the adjusted gear position, avoiding the automatic change of the wind speed and temperature of the smart hair dryer, so as to facilitate the use in the case of maintaining the air outlet in a constant state, and facilitate professionals to adjust according to their own needs. When the smart hair dryer is switched to the manual mode, the circuit component 40 controls the status indicator light 53 to turn off, and when the smart hair dryer is switched to the smart mode, the circuit component 40 controls the status indicator light 53 to turn on, so that the user can distinguish between the smart mode and the manual mode, that is, the user can intuitively understand whether the smart hair dryer is in the smart state, which improves the user's perception of the indication range of the smart mode, so that the user can adjust according to their own needs.

[0049] The technical solution of the utility model is to set the intelligent mode and the manual mode on the intelligent hair dryer, and set the distance sensor 51 and the status indicator light 53 at the end of the air outlet 102 on the intelligent hair dryer. When used in the intelligent mode, the distance sensor 51 can be used to detect the distance between the air outlet 102 and the blown object, and then the circuit component 40 controls the working state of the heating component 30 and the fan component 20 according to the distance signal measured by the distance sensor 51, so as to adjust the working state of the heating component 30 and the fan component 20 in real time according to the distance change between the air outlet 102 and the blown object, so that the wind temperature and air volume received by the blown object are kept within a reasonable range, thereby improving the intelligent effect of the intelligent hair dryer. The status indicator light 53 is turned on in the intelligent mode and turned off in the manual mode, so that the user can intuitively understand whether the intelligent hair dryer is in the intelligent state, so that the user can adjust it according to his own needs and it is convenient for the user to use.

In this way, the space in the handheld portion 12 can be used to form part of the air duct 103, which is conducive to reducing the size of the wind tube portion, thereby reducing the overall size of the smart wind tube. Of course, in other embodiments, the air inlet 101 can also be provided at one end of the wind tube portion away from the air outlet 102.

[0053] In some embodiments, the fan assembly 20 is disposed in the second flow channel 105, and the heating assembly 30 is disposed in the first flow channel 104 and is disposed adjacent to the air outlet 102. In this way, the fan assembly 20 can be installed using the space in the handheld portion 12, which is conducive to reducing the size of the air cylinder portion, thereby reducing the overall size of the smart air cylinder. By arranging the heating assembly 30 adjacent to the air outlet 102, the distance between the hot air flow heated by the heating assembly 30 and the air outlet 102 can be shortened, which is conducive to reducing heat loss.

[0054] In some embodiments, the smart hair dryer further includes a cold air switch 71, which is disposed on the handheld portion 12, and the circuit assembly 40 is electrically connected to the cold air switch 71, and the circuit assembly 40 is configured to control the heating assembly 30 to stop working when the cold air switch 71 is triggered.

The cold air switch 71 can be a mechanical button, a push switch, a touch button, etc.

[0055] In some embodiments, the smart hair dryer further includes a power switch 72, which is disposed on the handheld portion 12 and electrically connected to the circuit assembly 40, that is, the power switch 72 can be used to control the power on and off of the smart hair dryer, so that the user can pause the use of the hair dryer.

[0067] When the air nozzle is installed at the air outlet 102, the air nozzle sensor is triggered. After the circuit component 40 receives the trigger signal of the air nozzle sensor, it is determined that the air nozzle is installed at the air outlet 102. At this time, the distance sensor 51 is controlled to be closed, so that the smart hair dryer is switched to the manual mode. That is, when the user installs the air nozzle for use, it can automatically switch to the manual mode, avoiding the situation where the user manually switches the mode when installing the air nozzle for use, which is convenient for the user. The air nozzle sensor can be a Hall sensor, a micro switch or an infrared sensor, etc.

[0068] In some embodiments, the smart hair dryer includes a distance sensor 51 and a temperature sensor 52. The distance sensor 51 is arranged at one end of the shell component 10 where the air outlet 102 is located, and the circuit component 40 is electrically connected to the distance sensor 51 to adjust the working state of at least one of the fan component 20 and the heating component 30 according to the distance signal measured by the distance sensor 51; the temperature sensor 52 is arranged at one end of the shell component 10 where the air outlet 102 is located, and the circuit component 40 is electrically connected to the temperature sensor 52 to adjust the working state of at least one of the fan component 20 and the heating component 30 according to the temperature signal measured by the distance sensor 51.

[0069] The circuit assembly 40 can control the working states of the fan assembly 20, the heating assembly 30, the temperature sensor 52 and the distance sensor 51. For example, the power size and start and stop of the fan assembly 20 and the heating assembly 30 can be controlled, and the start and stop of the distance sensor 51 and the temperature sensor 52 can be controlled. The specific circuit structure of the circuit assembly 40 can refer to the prior art, and the utility model will not be described one by one.

[0070] The temperature sensor 52 is a non-contact temperature sensor 52, for example, the temperature sensor 52 may be an ultrasonic temperature sensor 52, a laser temperature sensor 52 or an infrared temperature sensor 52. The temperature sensor 52 and the air outlet 102 are located at the same end of the housing assembly 10. When in use, the air outlet 102 and the temperature sensor 52 may be directed toward the blown object (a person or an object) at the same time, and the temperature signal of the surface of the blown object may be measured by the temperature sensor 52.

[0071] The temperature sensor 52 transmits the temperature signal to the analog-to-digital converter of the circuit component 40, and the analog-to-digital converter performs analog-to-digital conversion to form digital information. The analog-to-digital converter transmits the digital information to the main control circuit of the circuit component 40, and the main control circuit determines the temperature information according to the digital information, and then adjusts the working state of at least one of the heating component 30 and the fan component 20 according to the temperature information, that is, the power of the fan component 20 and the heating component 30 can be automatically adjusted according to the temperature signal of the temperature sensor 52, so that the wind temperature and air volume received by the blown object are kept within a reasonable range. For example, when it is judged that the temperature of the blown object is high (one or more temperature thresholds can be preset for judgment, the same below), the heating power of the heating component 30 is reduced and / or the motor speed of the fan component 20 is increased through the circuit component 40; or, the heating component 30 is controlled to stop working. When it is judged that the temperature of the blown object is low, the heating power of the heating component 30 is increased through the circuit component 40, or the heating power of the heating component 30 and the motor speed of the fan component 20 are increased at the same time.

[0072] The technical solution of the utility model is to set a distance sensor 51 and a temperature sensor 52 at the end of the smart hair dryer with an air outlet 102. When in use, the distance sensor 51 can be used to detect the distance between the air outlet 102 and the blown object, and the temperature sensor 52 can be used to detect the temperature of the blown object. Then, the circuit component 40 controls the working state of the heating component 30 and the fan component 20 according to the distance signal measured by the distance sensor 51 and the temperature signal measured by the temperature sensor 52, thereby achieving real-time adjustment of the working state of the heating component 30 and the fan component 20 according to the change in the distance between the air outlet 102 and the blown object and the surface temperature of the blown object, thereby improving the judgment accuracy, so as to accurately adjust the air outlet temperature and wind speed of the smart hair dryer, so that the wind temperature and air volume received by the blown object are kept within a reasonable range, thereby improving the intelligent effect of the smart hair dryer and facilitating user use.

[0073] In some embodiments, the temperature sensor 52 and the distance sensor 51 are disposed on opposite sides of the air outlet 102. In this way, the overall detection range formed by the temperature sensor 52 and the distance sensor 51 can be larger, which is conducive to improving the detection accuracy. Of course, in other embodiments, the temperature sensor 52 and the distance sensor 51 are disposed on the same side or adjacent sides of the air outlet 102.

[0074] In some embodiments, the smart hair dryer includes a button assembly, which is electrically connected to the circuit assembly 40. The smart hair dryer has a smart mode and a manual mode. The circuit assembly 40 is configured to switch the smart hair dryer from the smart mode to the manual mode when the button assembly is triggered; the circuit assembly 40 is configured to adjust the working state of at least one of the fan assembly 20 and the heating assembly 30 according to the distance signal measured by the distance sensor 51 in the smart mode; the circuit assembly 40 is configured to adjust the working state of at least one of the fan assembly 20 and the heating assembly 30 according to the temperature signal measured by the distance sensor 51 in the smart mode.

[0075] By setting the smart mode and the manual mode in the smart hair dryer, when used in the smart mode, the distance sensor 51 can be used to detect the distance between the air outlet 102 and the blown object, and the temperature sensor 52 can be used to detect the temperature of the blown object. Then, the circuit component 40 controls the working state of the heating component 30 and the fan component 20 according to the distance signal measured by the distance sensor 51 and the temperature signal measured by the temperature sensor 52, thereby achieving real-time adjustment of the working state of the heating component 30 and the fan component 20 according to the distance change between the air outlet 102 and the blown object and the surface temperature of the blown object. Switching the smart hair dryer from the smart mode to the manual mode through the button component can facilitate manual selection by the user.

[0076] In some embodiments, the button assembly includes at least one of a temperature adjustment switch and a wind speed adjustment switch, the circuit assembly 40 is electrically connected to the temperature adjustment switch and the wind speed adjustment switch, and the circuit assembly 40 is configured to switch the smart hair dryer to manual mode when the temperature adjustment switch or the wind speed adjustment switch is triggered. In this way, using the temperature adjustment switch and the wind speed adjustment switch as trigger switches for exiting the smart mode can avoid setting up additional buttons, which can simplify the structure of the smart hair dryer. This is also in line with the logic of manually adjusting the wind temperature and wind speed through the temperature adjustment switch and the wind speed adjustment switch in manual mode, which can reduce the difficulty of user learning.

[0077] In some embodiments, the smart mode includes at least two modes of a child mode, a therapy mode, a hair care mode, and a quick-drying mode; the smart hair dryer also includes a mode switching switch 73, which is mounted on the housing assembly 10 and exposed to the outside, and the circuit assembly 40 is electrically connected to the mode switching switch 73 to switch the child mode, therapy mode, hair care mode, and quick-drying mode through the mode switching switch 73. This makes it easy for the user to manually select the desired mode, and avoids the situation where each mode corresponds to a button, which can reduce the number of buttons, facilitate operation, and simplify the structure of the smart hair dryer.

In some embodiments, the mounting cavity 113 is annular, the temperature sensor 52 is mounted in the mounting cavity 113, and is spaced from the distance sensor 51 in the circumferential direction of the air outlet 102.

[0079] In some embodiments, the air guide shell 112 includes an outer cylinder and an inner cylinder disposed inside the outer cylinder, an air duct 103 and an air outlet 102 are formed between the outer cylinder and the inner cylinder, one end of the outer cylinder and the inner cylinder forming the air outlet 102 is exposed to the outside, and the heating component 30 is disposed outside the inner cylinder. Optionally, the status indicator 53 is disposed on the inner cylinder. In this way, the heating component 30 and the status indicator 53 can be installed in the inner cylinder, which can improve the space utilization rate in the smart air duct.

[0080] In some embodiments, the air guide shell 112 includes a front shell 114, a middle shell 115 and a rear shell 116. The middle shell 115 is cylindrical and connected between the front shell 114 and the rear shell 116. The front shell 114 and the rear shell 116 are connected by an intermediate structure 117 in the middle shell 115. The intermediate structure 117 is spaced from the middle shell 115 to form an air duct 103 between the front shell 114, the middle shell 115 and the rear shell 116. An air outlet 102 is provided at one end of the front shell 114 away from the rear shell 116. The heating component 30 is at least partially installed between the intermediate structure 117 and the middle shell 115. Specifically, the front shell 114, the middle shell 115 and the rear shell 116 are formed separately and fixed by assembly, which can simplify the structure of the front shell 114, the middle shell 115 and the rear shell 116, reduce the difficulty of forming the air guide shell 112, and facilitate the installation of the heating component 30. In one embodiment, the intermediate structure 117 and a portion of the front shell 114 connected to the intermediate structure 117 form a partial inner cylinder portion, and the middle shell 115 and a portion of the front shell 114 connected to the middle shell 115 form a partial outer cylinder portion.

The plurality of mounting structures 118 are spaced apart along the circumference of the intermediate structure 117. Each support plate 31 is correspondingly mounted on a mounting structure 118 and extends in a direction from the rear shell 116 to the front shell 114. The heating wires are wound around the plurality of support plates 31.
