[0020] The present utility model proposes a smart hair dryer.

[0021] In the embodiments of the present utility model, as shown in FIGS. 1 to 7, the smart hair dryer includes a housing assembly 10, a circuit assembly 40, and a distance sensor 51. The housing assembly 10 is provided with an air inlet 101, an air outlet 102, and a duct 103 formed between the air inlet 101 and the air outlet 102. The air outlet 102 is located at one end of the housing assembly 10, and a fan assembly 20 and a heating assembly 30 are provided in the duct 103.

[0022] The circuit assembly 40 is provided in the housing assembly 10 and connects the fan assembly 20 and the heat - generating assembly 30. The distance sensor 51 is provided at one end of the housing assembly 10 where the air outlet 102 is located. The circuit assembly 40 is electrically connected to the distance sensor 51, and thereby adjusts the operating state of at least one of the fan assembly 20 and the heat - generating assembly 30 based on the distance signal measured by the distance sensor 51 in the smart mode. Specifically, one end of the duct 103 communicates with the air inlet 101, and the other end communicates with the air outlet 102. The hair dryer can drive the external air flow from the air inlet 101 into the duct 103, and after passing through the heat - generating assembly 30, blow it out from the air outlet 102.

[0023] The circuit assembly 40 includes a circuit board and a control circuit provided on the circuit board, and thereby the circuit assembly 40 controls the operating states of the fan assembly 20, the heat - generating assembly 30, and the distance sensor 51. For example, it controls the power magnitude and start / stop of the fan assembly 20 and the heat - generating assembly 30, and controls the start / stop of the distance sensor 51. The specific circuit structure of the circuit assembly 40 may refer to the prior art, and the present utility model will not mention it sequentially here.

[0024] The distance sensor 51 is located at the same end of the air outlet 102 and the housing assembly 10. During use, the air outlet 102 and the distance sensor 51 can be simultaneously directed towards the object to be blown (a person or an object). At this time, the distance sensor 51 can measure the distance signal from the object to be blown, that is, the distance between the air outlet 102 and the object to be blown.

[0025] The distance sensor 51 transmits a distance signal to the analog-to-digital converter of the circuit assembly 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 master circuit of the circuit assembly 40, and the master circuit determines distance information based on the digital information, and further adjusts the operating state of at least one of the heating assembly 30 and the fan assembly 20 based on the distance information, and automatically adjusts the power of the fan assembly 20 and the heating assembly 30 based on the distance signal of the distance sensor 51, so as to maintain the air temperature and air volume received by the spraying target within a reasonable range. For example, when it is determined that the distance between the air outlet 102 and the spraying target is relatively close (one or more distance thresholds may be preset for determination, the same applies hereinafter), the circuit assembly 40 reduces the heating power of the heating assembly 30, or simultaneously reduces the heating power of the heating assembly 30 and the motor rotation speed of the fan assembly 20, or controls to stop the operation of the heating assembly 30. When it is determined that the distance between the air outlet 102 and the spraying target is relatively far, the circuit assembly 40 increases the heating power of the heating assembly 30 and / or increases the motor rotation speed of the fan assembly 20. Here, the distance sensor 51 includes one or more of a laser distance measuring sensor, an infrared distance measuring sensor, or a radar distance measuring sensor.

[0026] By providing the distance sensor 51 at the end where the air outlet 102 is located, the distance sensor 51 detects the distance between the air outlet 102 and the spraying target, and further, the circuit assembly 40 controls the operating states of the heating assembly 30 and the fan assembly 20 based on the distance signal measured by the distance sensor 51, so as to realize the real-time adjustment of the operating states of the heating assembly 30 and the fan assembly 20 based on the distance change between the air outlet 102 and the spraying target, maintain the air temperature and air volume received by the spraying target within a reasonable range, improve the smart effect of the smart hair dryer, and improve the comfort and safety of the user during use.

[0027] In some embodiments, the smart hair dryer has a smart mode and a manual mode, and the circuit assembly 40 is electrically connected to the distance sensor 51, thereby adjusting the operating state of at least one of the fan assembly 20 and the heating assembly 30 based on the distance signal measured by the distance sensor 51 in the smart mode.

[0028] The smart hair dryer is provided at one end where the air outlet 102 in the housing assembly 10 is located, and is further electrically connected to the circuit assembly 40, and further includes a status indicator lamp 53 configured to be on in the smart mode and off in the manual mode.

[0029] Specifically, the distance sensor 51 is in an on state in the smart mode and in an off state in the manual mode. That is, in the manual mode, both the wind speed and the temperature of the smart hair dryer are manually controlled by the user, and can be kept constant under the gear where the wind speed and the temperature of the smart hair dryer are adjusted, avoiding the automatic change of the wind speed and the temperature of the smart hair dryer, and being easy to use when it is necessary to maintain a constant state to blow air, and experts can adjust themselves according to their own needs. When the smart hair dryer is switched to the manual mode, the circuit assembly 40 controls the status indicator lamp 53 to be off, and when the smart hair dryer is switched to the smart mode, the circuit assembly 40 controls the status indicator lamp 53 to be on, whereby the user can easily distinguish between the smart mode and the manual mode, that is, the user can intuitively and easily know whether the smart hair dryer is in the smart state, improving the user's perception of the smart mode indication range, and the user can easily adjust according to their own needs.

[0030] The technical solution of this utility model is to set a smart mode and a manual mode for the smart hair dryer, and a distance sensor 51 and a status indicator lamp 53 are provided at the end of the smart hair dryer where the air outlet 102 is provided. When used in the smart mode, the distance sensor 51 detects the distance between the air outlet 102 and the object to be blown, and further, the circuit assembly 40 controls the operating states of the heating assembly 30 and the fan assembly 20 based on the distance signal measured by the distance sensor 51, so as to realize the real-time adjustment of the operating states of the heating assembly 30 and the fan assembly 20 based on the change in the distance between the air outlet 102 and the object to be blown, thereby maintaining the air temperature and air volume received by the object to be blown within a reasonable range and improving the smart effect of the smart hair dryer. The status indicator lamp 53 is turned on in the smart mode and turned off in the manual mode, so that the user can intuitively know whether the smart hair dryer is in the smart state, the user can easily adjust according to their own needs, and the user is more convenient to use.

[0031] In some embodiments, an attachment position 106 is provided at the end of the housing assembly 10 where the air outlet 102 is provided. The air outlet 102 surrounds the peripheral side of the attachment position 106, and the status indicator lamp 53 is located at the attachment position 106. That is, the status indicator lamp 53 is located in the middle region of the end of the housing assembly 10 approximately, so that the user can observe easily and make full use of the space in the middle region.

[0032] In some embodiments, the end of the housing assembly 10 where the air outlet 102 is provided has an annular region 107. The annular region 107 surrounds the peripheral side of the air outlet 102, and the distance sensor 51 is provided in the annular region 107. In this way, the space utilization rate can be improved by using the position around the air outlet 102. Of course, in other embodiments, the distance sensor 51 may be provided at the attachment position 106, or the status indicator lamp 53 may be provided in the annular region 107.

[0033] In some embodiments, the housing assembly 10 includes a hair dryer portion and a handset 12 connected to a side of the hair dryer portion. An air outlet 102 is provided at one end of the hair dryer portion, and an air inlet 101 is provided in the handset 12. The duct 103 includes a first flow path 104 located within the hair dryer portion and a second flow path 105 located within the handset 12 and communicating with the first flow path 104. In this way, a part of the duct 103 can be formed by the space within the handset 12, which is advantageous for reducing the overall size of the smart hair dryer by reducing the size of the hair dryer portion. Of course, in other embodiments, the air inlet 101 may be provided at one end of the hair dryer portion away from the air outlet 102.

[0034] In some embodiments, a fan assembly 20 is provided within the second flow path 105, and a heating assembly 30 is provided within the first flow path 104 and adjacent to the air outlet 102. In this way, the fan assembly 20 can be installed using the space within the handset 12, which is advantageous for reducing the overall size of the smart hair dryer by reducing the size of the hair dryer portion. By providing 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 is shortened, which is advantageous for reducing heat loss.

[0035] In some embodiments, the smart hair dryer further includes a cold air switch 71 provided in the handset 12. The circuit assembly 40 is electrically connected to the cold air switch 71 and is configured to control the operation of the heating assembly 30 to stop when the cold air switch 71 is triggered. That is, whether in manual mode or smart mode, when the user triggers the cold air switch 71, the circuit assembly 40 controls to stop the operation of the heating assembly 30 in both cases to realize cold air supply, and in this way, the user's hair styling can be facilitated. The cold air switch 71 may be a mechanical key, a push key, a touch key, or the like.

[0036] In some embodiments, the smart hair dryer further includes a power switch 72 provided on the handset 12 and electrically connected to the circuit assembly 40, that is, the power switch 72 can control the on / off of the smart hair dryer, and it is easy for the user to temporarily stop using it in the middle. The power switch 72 may be a mechanical key, a push key, a touch key, or the like.

[0037] In some embodiments, the smart mode includes at least two modes among the child mode, the physical therapy mode, the hair care mode, and the quick drying mode. The heating temperature of the heating assembly 30 in the child mode is lower than the heating temperature of the heating assembly 30 in the physical therapy mode. The heating temperature of the heating assembly 30 in the physical therapy mode is lower than the heating temperature of the heating assembly 30 in the hair care mode. The heating temperature of the heating assembly 30 in the hair care mode is lower than the heating temperature of the heating assembly 30 in the quick drying mode. The motor rotation speed of the fan assembly 20 in the physical therapy mode is lower than the motor rotation speed of the fan assembly 20 in the child mode. The motor rotation speed of the fan assembly 20 in the child mode is lower than the motor rotation speed of the fan assembly 20 in the hair care mode. The motor rotation speed of the fan assembly 20 in the hair care mode is lower than the motor rotation speed of the fan assembly 20 in the quick drying mode. Specifically, the child mode can be used by children. For example, it can be used to dry children's hair and uses a low temperature to avoid burns. The quick drying mode adopts high temperature and high-speed air flow and can quickly dry hair or dry laundry. The physical therapy mode and the hair care mode have appropriate temperature and wind speed and can be used for the warm compress function and slowly drying hair. By setting multiple modes in this way, it becomes easier for the user to select and use according to their needs, and the practicality of the smart hair dryer can be improved.

[0038] Optionally, the blowing temperature in the child mode is 45°C or higher and 55°C or lower, and the motor rotation speed of the fan assembly 20 is 85,000 RPM or higher and 90,000 RPM or lower. Specifically, the blowing temperature in the child mode may be 45°C, 48°C, 50°C, 52°C, or 55°C, and the motor rotation speed of the fan assembly 20 is 80,000 RPM (revolutions per minute) or higher and 90,000 RPM or lower. The motor rotation speed of the fan assembly 20 may be 85,000 RPM, 86,000 RPM, 88,000 RPM, or 90,000 RPM.

[0039] The blowing temperature in the physical therapy mode is 55°C or higher and 65°C or lower, and the motor rotation speed of the fan assembly 20 is 75,000 RPM or higher and 85,000 RPM or lower. Specifically, the blowing temperature in the physical therapy mode may be 55°C, 58°C, 60°C, 62°C, or 65°C, and the motor rotation speed of the fan assembly 20 may be 75,000 RPM, 78,000 RPM, 80,000 RPM, 82,000 RPM, or 85,000 RPM.

[0040] The blowing temperature in the hair care mode is 70°C or higher and 80°C or lower, and the motor rotation speed of the fan assembly 20 is 90,000 RPM or higher and 100,000 RPM or lower. Specifically, the blowing temperature in the hair care mode may be 70°C, 72°C, 75°C, 78°C, or 80°C, and the motor rotation speed of the fan assembly 20 may be 90,000 RPM, 92,000 RPM, 95,000 RPM, 98,000 RPM, or 100,000 RPM.

[0041] The blowing temperature in the quick-dry mode is 85°C or higher and 90°C or lower, and the motor rotation speed of the fan assembly 20 is 100,000 RPM or higher and 120,000 RPM or lower. Specifically, the blowing temperature in the quick-dry mode may be 85°C, 86°C, 88°C, or 90°C, and the motor rotation speed of the fan assembly 20 may be 100,000 RPM, 105,000 RPM, 110,000 RPM, 115,000 RPM, or 120,000 RPM.

[0042] In some embodiments, the smart hair dryer further includes a mode switching switch 73 attached to the housing assembly 10 and exposed to the outside. The circuit assembly 40 is electrically connected to the mode switching switch 73, thereby switching the child mode, physical therapy mode, hair care mode, and quick-drying mode by the mode switching switch 73. The status indicator lamp 53 is configured to be on in at least one of the child mode, physical therapy mode, hair care mode, and quick-drying mode. Specifically, taking the example that the smart hair dryer includes the child mode, physical therapy mode, hair care mode, and quick-drying mode, when the mode switching switch 73 is triggered, the smart hair dryer can be switched among the child mode, physical therapy mode, hair care mode, and quick-drying mode. In this way, it is easy for the user to manually select and use the required mode, and it is possible to avoid providing one key for each mode, reduce the number of keys, make the operation easy, and simplify the structure of the smart hair dryer. The mode switching switch 73 may be a mechanical key, a push key, a touch key, or the like.

[0043] In this embodiment, the status indicator lamp 53 is turned on in the physical therapy mode and turned off in all of the child mode, hair care mode, and quick-drying mode, thus improving the user's perception of the indication range of the physical therapy mode.

[0044] In some embodiments, the smart hair dryer further 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. The circuit assembly 40 is configured to switch the smart hair dryer to the manual mode when the temperature adjustment switch or the wind speed adjustment switch is triggered. That is, by triggering the temperature adjustment switch, the heating temperature of the heating assembly 30 can be adjusted, and by triggering the wind speed adjustment switch, the motor rotation speed of the fan assembly 20 can be adjusted. At the same time, when the circuit assembly 40 receives a signal that the temperature adjustment switch or the wind speed adjustment switch is triggered, the smart hair dryer is switched to the manual mode (i.e., turning off the distance sensor 51). In this way, by using the temperature adjustment switch and the wind speed adjustment switch as the trigger switches to exit the smart mode, it is possible to avoid providing a separate key and simplify the structure of the smart hair dryer. This also conforms to the logic of manually adjusting the wind temperature and wind speed by the temperature adjustment switch and the wind speed adjustment switch in the manual mode, and can reduce the learning difficulty of the user. Here, when the temperature adjustment switch and the wind speed adjustment switch are provided at the same time, the circuit assembly 40 controls to switch the smart hair dryer to the manual mode when receiving a signal that either the temperature adjustment switch or the wind speed adjustment switch is triggered. The temperature adjustment switch may be a mechanical key, a push key, a touch key, or the like. The wind speed adjustment switch may be a mechanical key, a push key, a touch key, or the like.

[0045] In some embodiments, the temperature adjustment switch and / or the wind speed adjustment switch is provided on the end face opposite to the air outlet 102 of the hair dryer part. In this way, the space on the hair dryer part can be fully utilized, which is advantageous for reducing the size of the handset 12.

[0046] In some embodiments, the smart hair dryer further includes a display 60 provided at an end away from the air outlet 102 of the hair dryer part and electrically connected to the circuit assembly 40. In this way, the user can easily check the state of the smart hair dryer. Optionally, the temperature adjustment switch and / or the wind speed adjustment switch are located on one side of the display 60.

[0047] In some embodiments, at the end of the housing assembly 10 where the air outlet 102 is provided, a blower nozzle connection structure and a blower nozzle sensor are further provided. The blower nozzle sensor is electrically connected to the circuit assembly 40. The blower nozzle connection structure is used to attach and fix the blower nozzle. The blower nozzle sensor is used to detect whether a blower nozzle is attached to the air outlet 102. When the blower nozzle sensor detects that a blower nozzle is attached to the air outlet 102, the circuit assembly 40 is further configured to switch the smart hair dryer to the manual mode. Specifically, the blower nozzle is fitted with the blower nozzle connection structure and attached to the air outlet 102. The blower nozzle connection structure may specifically be a screw structure (a corresponding screw structure is also provided for the air nozzle), a magnetic attraction structure, a buckle structure, etc.

[0048] When the blower nozzle is attached to the air outlet 102, the blower nozzle sensor is triggered. After receiving the trigger signal of the blower nozzle sensor, the circuit assembly 40 determines that a blower nozzle is attached to the air outlet 102. At this time, the distance sensor 51 is controlled to be turned off, and the smart hair dryer is switched to the manual mode. That is, when the user attaches the blower nozzle in this way, it can be automatically switched to the manual mode, avoiding the situation where the user manually switches the mode when attaching and using the blower nozzle, and facilitating the user's use. The blower nozzle sensor may be a hall sensor, a micro switch, an infrared sensor, etc.

[0049] In some embodiments, the smart hair dryer includes a distance sensor 51 and a temperature sensor 52. The distance sensor 51 is provided at one end of the housing assembly 10 where the air outlet 102 is located. The circuit assembly 40 is electrically connected to the distance sensor 51, thereby adjusting the operating state of at least one of the fan assembly 20 and the heating assembly 30 based on the distance signal measured by the distance sensor 51. The temperature sensor 52 is provided at one end of the housing assembly 10 where the air outlet 102 is located. The circuit assembly 40 is electrically connected to the temperature sensor 52, thereby adjusting the operating state of at least one of the fan assembly 20 and the heating assembly 30 based on the temperature signal measured by the distance sensor 51.

[0050] The circuit assembly 40 can control the operating states of the fan assembly 20, the heating assembly 30, the temperature sensor 52, and the distance sensor 51. For example, it can control the power magnitude and start / stop of the fan assembly 20 and the heating assembly 30, and the start / stop of the distance sensor 51 and the temperature sensor 52. The specific circuit structure of the circuit assembly 40 may refer to the prior art, and the present utility model will not mention it sequentially here.

[0051] 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 is located at the same end of the air outlet 102 and the housing assembly 10. During use, the air outlet 102 and the temperature sensor 52 can be simultaneously directed towards the object to be blown (a person or an object). At this time, the temperature sensor 52 can measure the temperature signal of the surface of the object to be blown.

[0052] The temperature sensor 52 transmits a temperature signal to the analog-to-digital converter of the circuit assembly 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 master circuit of the circuit assembly 40. The master circuit determines temperature information based on the digital information, and further adjusts the operating state of at least one of the heating assembly 30 and the fan assembly 20 based on the temperature information, and automatically adjusts the power of the fan assembly 20 and the heating assembly 30 based on the temperature signal of the temperature sensor 52, so as to maintain the air temperature and air volume received by the object to be blown within a reasonable range. For example, when it is determined that the temperature of the object to be blown is relatively high (one or more temperature thresholds may be preset for determination, and the same applies hereinafter), the circuit assembly 40 reduces the heating power of the heating assembly 30, or simultaneously reduces the motor rotation speed of the fan assembly 20, or stops the operation of the heating assembly 30. When it is determined that the temperature of the object to be blown is relatively low, the circuit assembly 40 increases the heating power of the heating assembly 30, or simultaneously increases the heating power of the heating assembly 30 and the motor rotation speed of the fan assembly 20.

[0053] The technical solution of this utility model is that a distance sensor 51 and a temperature sensor 52 are provided at the end of the smart hair dryer where the air outlet 102 is provided. During use, the distance sensor 51 detects the distance between the air outlet 102 and the object to be blown, and the temperature sensor 52 detects the temperature of the object to be blown. Furthermore, the circuit assembly 40 controls the operating states of the heating assembly 30 and the fan assembly 20 based on the distance signal measured by the distance sensor 51 and the temperature signal measured by the temperature sensor 52, so as to adjust the operating states of the heating assembly 30 and the fan assembly 20 in real time based on the distance change between the air outlet 102 and the object to be blown and the surface temperature of the object to be blown, and improve the accuracy of determination. Thereby, the blowing temperature and wind speed of the smart hair dryer can be accurately adjusted, the air temperature and air volume received by the object to be blown are maintained within a reasonable range, the smart effect of the smart hair dryer is improved, and the use of the user can be facilitated.

[0054] In some embodiments, the temperature sensor 52 and the distance sensor 51 are respectively provided 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 enlarged, which is advantageous for improving the detection accuracy. Of course, in other embodiments, the temperature sensor 52 and the distance sensor 51 are provided on the same side or adjacent sides of the air outlet 102.

The circuit assembly 40 is configured to switch the smart hair dryer from the smart mode to the manual mode when the key assembly is triggered. The circuit assembly 40 is configured to adjust the operating state of at least one of the fan assembly 20 and the heating assembly 30 based on the distance signal measured by the distance sensor 51 in the smart mode. The circuit assembly 40 is configured to adjust the operating state of at least one of the fan assembly 20 and the heating assembly 30 based on the temperature signal measured by the temperature sensor 52 in the smart mode.

[0056] By setting the smart mode and the manual mode for the smart hair dryer, when using in the smart mode, the distance sensor 51 detects the distance between the air outlet 102 and the object to be blown, the temperature sensor 52 detects the temperature of the object to be blown, and further the circuit assembly 40 controls the operating states of the heating assembly 30 and the fan assembly 20 based on the distance signal measured by the distance sensor 51 and the temperature signal measured by the temperature sensor 52, so that the operating states of the heating assembly 30 and the fan assembly 20 can be adjusted in real time based on the distance change between the air outlet 102 and the object to be blown and the surface temperature of the object to be blown. By switching the smart hair dryer from the smart mode to the manual mode by the key assembly, it is easier for the user to select and use manually.

[0057] In some embodiments, the key assembly further includes at least one of a temperature control switch and a wind speed control switch. The circuit assembly 40 is electrically connected to the temperature control switch and the wind speed control switch. The circuit assembly 40 is configured to switch the smart hair dryer to the manual mode when the temperature control switch or the wind speed control switch is triggered. In this way, by using the temperature control switch and the wind speed control switch as the trigger switches to exit the smart mode, it is possible to avoid providing a separate key and simplify the structure of the smart hair dryer. This also conforms to the logic of manually adjusting the wind temperature and wind speed by the temperature control switch and the wind speed control switch in the manual mode, and can reduce the learning difficulty of the user.

The circuit assembly 40 is electrically connected to the mode switch 73, thereby switching the child mode, the physical therapy mode, the hair care mode, and the quick drying mode by the mode switch 73. In this way, it is easy for the user to manually select and use the required mode, and it is possible to avoid providing one key for each mode, reduce the number of keys, make the operation easy, and simplify the structure of the smart hair dryer.

[0061] In some embodiments, the air guiding case 112 includes a front case 114, a middle case 115 and a rear case 116. The middle case 115 is cylindrical and is connected between the front case 114 and the rear case 116. The front case 114 and the rear case 116 are connected by an intermediate structure 117 within the middle case 115. The intermediate structure 117 is spaced from the middle case 115, thereby forming a duct 103 between the front case 114, the middle case 115 and the rear case 116. An air outlet 102 is provided at one end of the front case 114 away from the rear case 116. At least a part of the heat generating assembly 30 is mounted between the intermediate structure 117 and the middle case 115. Specifically, the front case 114, the middle case 115 and the rear case 116 are separately formed and fixed by assembly.
