Description

Technical Field

[0001] This disclosure relates to the field of hair dryer technology, and in particular to hair dryers. Background Technology

[0002] Hair dryer airflow patterns typically include converging and diffuser types. Converging airflow provides a concentrated, high-speed airflow, suitable for quick drying, precise styling such as inward curls or curls. Diffuser airflow increases the airflow coverage area, suitable for natural, voluminous effects, but is slightly less efficient at drying long hair than converging airflow.

[0003] In related technologies, it is necessary to switch between converging and diffusing airflow patterns to achieve the desired blowing effect. However, this airflow pattern switching usually requires replacing the nozzle, which complicates the operation and reduces blowing efficiency. Summary of the Invention

[0004] This disclosure provides a hair dryer to solve related technical problems.

[0005] According to a first aspect of the present disclosure, a hair dryer is provided, comprising: a device body, a movable part, and a drive mechanism, wherein the movable part is movably assembled to the device body;

[0006] The main body of the device includes an air outlet port; the drive mechanism is connected to the movable component to drive the movable component to move relative to the air outlet port and change the air outlet parameters of the air outlet port.

[0007] The hair dryer includes movable parts that are movably assembled into the device housing. A drive mechanism can drive the movable parts to move relative to the air outlet, thereby changing the air outlet parameters. This solution, through the drive mechanism and movable parts, achieves adjustment of the air outlet parameters, improving the ease of switching airflow patterns and thus enhancing the user experience of the hair dryer.

[0008] Optionally, the device body includes a distance sensor for detecting the sensing distance between the distance sensor and the surface to be blown; the control board of the device body is electrically connected to the distance sensor to adjust at least one of the air temperature and air volume of the hair dryer according to the sensing distance. The control signal of the hair dryer to the drive mechanism can be associated with the sensing distance between the hair dryer and the surface to be blown, so that the hair dryer can adjust at least one of the air temperature and air volume according to the sensing distance.

[0009] Optionally, the distance sensor is assembled at the air outlet port to facilitate the distance sensor in measuring the distance between the air outlet port and the surface to be blown.

[0010] Optionally, the main body of the device also includes a heat insulation cylinder, and the distance sensor is assembled inside the heat insulation cylinder. The heat insulation cylinder is used to isolate the heat transfer between the heating element and the second air duct. Assembling the distance sensor inside the heat insulation cylinder can avoid the influence of the heating element on the distance sensor.

[0011] Optionally, the movable component includes a rotating structure rotatably assembled to the main body of the equipment, the main body of the equipment including a housing, and the housing having a fixing structure;

[0012] At least one of the fixed structure and the rotating structure is provided with the air outlet port, and at least one of the fixed structure and the rotating structure is provided with a shielding structure; the driving mechanism drives the rotating structure to rotate relative to the fixed structure, so that the shielding structure moves relative to the air outlet port, thereby changing the air outlet parameters. The rotation operation of the rotating structure allows for the coordination of the air outlet port and the shielding structure to change the air outlet parameters, reducing the space occupied and improving operational convenience.

[0013] Optionally, the rotating structure includes a windproof rotating cylinder rotatably assembled within the housing;

[0014] The air outlet port includes a first opening and a second opening that penetrate the side wall of the housing, wherein the air outlet area and / or air outlet angle of the first opening and the second opening are different.

[0015] The shielding structure includes multiple baffles disposed on the wind-blown rotating cylinder. When the wind-blown rotating cylinder rotates to a first position, the baffles block the first opening and avoid the second opening, allowing airflow from the device body to exit through the second opening. When the wind-blown rotating cylinder rotates to a second position, the baffles block the second opening and avoid the first opening, allowing airflow from the device body to exit through the first opening. By providing two types of openings in the housing, and by using baffles to avoid one type and block the other, the airflow parameters can be switched, which helps simplify the structure.

[0016] Optionally, the main body of the equipment includes a housing and a mounting component assembled within the housing, and the rotating structure includes a windproof rotating cylinder rotatably assembled to the outer wall of the mounting component;

[0017] The air outlet port includes a first opening and a second opening that penetrate the side wall of the housing, wherein the air outlet area and / or air outlet angle of the first opening and the second opening are different.

[0018] The shielding structure includes multiple baffles disposed on the windproof rotating cylinder. When the windproof rotating cylinder rotates to a first position, the baffles partially shield the first opening and partially obstruct the second opening, thereby forming a first type of airflow parameter when the airflow from the outlet duct blows out from the first opening and the second opening. When the windproof rotating cylinder rotates to a second position, the baffles partially shield the first opening and partially obstruct the second opening, thereby forming a second type of airflow parameter when the airflow from the outlet duct blows out from the first opening and the second opening. By providing two types of openings in the housing, and by partially obstructing one opening and partially shielding the other, the first and second airflow parameters can be switched, which helps to simplify the structure, enrich the airflow parameters, and expand the application scenarios of the blower.

[0019] Optionally, the main body of the device further includes a fixed ring, and the rotating structure includes a rotating ring located axially inside the fixed ring; the air outlet includes a third opening and a fourth opening disposed in the fixed ring; the rotating ring is provided with a fifth opening that matches the structure of the third opening and a sixth opening that matches the structure of the fourth opening;

[0020] The fixed ring is fixedly assembled to the housing, and the rotating ring is driven by the drive mechanism to rotate relative to the fixed ring. When the rotating ring is in the third position, the third opening and the fifth opening communicate to form a first through hole, the fixed ring blocks the sixth opening, and the rotating ring blocks the fourth opening, so that the airflow inside the device body blows out from the first through hole. When the rotating ring is in the fourth position, the fourth opening and the sixth opening communicate to form a second through hole, the fixed ring blocks the fifth opening, and the rotating ring blocks the third opening, so that the airflow inside the device body blows out from the second through hole. The first through hole and the second through hole have different air outlet areas and / or air outlet angles. The openings on the rotating ring and the fixed ring, respectively, and the through hole formed by the connection of the openings on the two components during rotation, help increase the length of the air outlet duct, reduce space occupation, reduce wind resistance, improve structural reliability, and facilitate precise control of the air outlet angle.

[0021] Optionally, the main body of the device includes a housing and a mounting component assembled within the housing, and the movable component includes a guide ring movably assembled to the outer wall of the mounting component; the housing and the mounting component form the air outlet port;

[0022] The guide ring includes an outer contour facing the housing, and the housing includes an inner contour matching the shape of the outer contour. The outer contour includes a first segment and a second segment arranged along the axial direction of the guide ring, wherein the cross-sectional dimension of the first segment is smaller than that of the second segment. The driving mechanism drives the guide ring to move axially to change the air outlet area and / or air outlet angle of the air outlet port. The size of the air outlet area can be adjusted by pushing and pulling the guide ring, thereby changing the air outlet parameters and simplifying the structural design.

[0023] Optionally, one of the outer wall of the mounting component and the inner surface of the guide ring is provided with a guide groove, and the other is provided with a guide rib, the guide rib being slidably assembled to the guide groove.

[0024] The guide ring can move along the guide groove, improving motion accuracy and reliability, and preventing the guide ring from rotating and deviating, which would generate resistance and affect the overall motion mechanism.

[0025] Optionally, the drive mechanism includes a third motor and a connecting component connected to the output end of the third motor; the movable component is drively connected to the connecting component, so that the third motor drives the connecting component to move the movable component relative to the air outlet port. Driving the connecting component with a third motor helps simplify the drive mechanism and its control logic.

[0026] Optionally, the connecting component includes a first connector, and the third motor is electrically connected to the control motherboard of the device body; one of the first connector and the movable component is provided with a slide groove that is axially inclined relative to the device body, and the other is provided with a slider, which is slidably assembled into the slide groove to drive the movable component to rotate relative to the air outlet port. The movable component is driven by the slider and the inclined slide groove, reducing the transmission structure and lowering the space occupied by the drive mechanism.

[0027] Optionally, the connecting component includes a second connector, wherein the third motor is electrically connected to the control board of the main body of the device; the second connector is connected to the output end of the third motor and the movable component respectively, so as to drive the movable component to move relative to the air outlet port. Directly realizing the transmission between the third motor and the movable component through the second connector helps to reduce the complexity of the transmission structure and improve the reliability of the transmission structure.

[0028] Optionally, the connecting component includes a gear assembly, and the third motor is electrically connected to the control motherboard of the main body of the device; the output end of the third motor meshes with the input gear of the gear assembly, and the output gear of the gear assembly meshes with the movable component to drive the movable component to rotate relative to the air outlet port.

[0031] The first motor and the heating element are assembled in the first air duct; the control board of the main body of the device is electrically connected to the first motor and the heating element respectively;

[0032] The second motor is assembled in the second air duct; the control board of the main body of the device is electrically connected to the second motor. The first motor and the heating element are located in the first air duct, and the second motor is located in the second air duct, so that the heat from the heating element has no effect on the air temperature in the second air duct. Therefore, it helps to achieve decoupled control of air volume and air temperature, and improves the control flexibility and accuracy of the air outlet parameters.

[0033] Optionally, the main body of the device further includes a first air outlet connected to the first air duct, and a second air outlet located circumferentially outside the first air outlet. The airflow pattern can be optimized by using the positions of the first and second air outlets.

Detailed Implementation

[0056] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0057] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0058] Hair dryer airflow patterns typically include focused and diffused patterns. Focused airflow provides a concentrated, high-speed airflow, suitable for quick drying, precise styling such as inward curls or curls. Diffuse airflow increases the airflow coverage area, suitable for natural, voluminous effects, but its drying efficiency for long hair is slightly lower than focused airflow. In related technologies, it's necessary to switch between focused and diffused airflow patterns to achieve the desired drying effect. However, this switching usually requires changing the nozzle, making the operation complex and reducing drying efficiency.

[0059] A hair dryer is provided according to an embodiment of the present disclosure. Figure 1 This is a schematic cross-sectional view of a hair dryer according to an exemplary embodiment of the present disclosure. Figure 2This is a three-dimensional structural diagram of a hair dryer according to an exemplary embodiment of the present disclosure, such as... Figure 1 , Figure 2 As shown, the hair dryer 1 includes: a device body 11, a movable part 114, and a drive mechanism 14. The movable part 114 is movably assembled to the device body 11. The drive mechanism 14 is connected to the movable part 114 for transmission, so as to drive the movable part 114 to move relative to the air outlet 113 and change the air outlet parameters of the air outlet 113.

[0060] The aforementioned hair dryer 1 includes a movable part 114, which is movably assembled to the main body 11. The drive mechanism 14 can drive the movable part 114 to move relative to the air outlet 113, thereby changing the air outlet parameters of the air outlet 113. This solution, through the drive mechanism 14 and the movable part 114, achieves adjustment of the air outlet parameters, which helps improve the ease of operation for switching airflow patterns, thus enhancing the user experience of the hair dryer 1. Furthermore, it helps reduce the number of accessories (in the prior art, different accessories are required to connect to the main body of the device to change the air outlet parameters, such as wind direction and wind speed), thereby reducing costs.

[0061] It should be noted that the aforementioned drive mechanism 14 may include an operating component that is transmissionally connected to the movable part 114, allowing the user to manually operate the drive mechanism 14 to move the movable part 114 relative to the air outlet 113. Alternatively, the drive mechanism 14 may also include a motor, which drives a transmission assembly to move the movable part 114 relative to the air outlet 113. In both manual operation and motor-driven movable part 114 cases, the drive mechanism 14 may include the following transmission methods:

[0062] The main body of the equipment 11 may include a housing 115 and a mounting component 16 located within the housing 115, and the movable component 114 may be assembled to the mounting component 16.

[0063] In some embodiments, the rotating structure includes a wind-blocking rotary cylinder rotatably assembled within the housing 115. For example, the movable component 114 includes a rotating structure rotatably assembled to the outer wall of the mounting component 16, and the housing 115 is provided with a fixed structure. At least one of the fixed structure and the rotating structure is provided with an air outlet port 113, and at least one of the fixed structure and the rotating structure is provided with a shielding structure 1141. The driving mechanism 14 drives the rotating structure to rotate relative to the fixed structure, so that the shielding structure 1141 moves relative to the air outlet port 113, thereby changing the air outlet parameters. By utilizing the rotation operation of the rotating structure, the air outlet port 113 and the shielding structure 1141 can cooperate to change the air outlet parameters, reducing the operating space occupied and improving operational convenience.

[0064] Among them, such as Figures 3-10As shown, the main body 11 of the device includes a housing 115 and a mounting component 16 assembled within the housing 115. The rotating structure includes a wind-blocking rotary cylinder rotatably assembled to the outer wall of the mounting component 16. The air outlet port 113 includes a first opening 1132a and a second opening 1132b penetrating the side wall of the housing 115. The air outlet area and / or air outlet angle of the first opening 1132a and the second opening 1132b are different. The shielding structure 1141 includes a plurality of baffles disposed on the wind-blocking rotary cylinder. When the wind-blocking rotary cylinder rotates to the first position, the baffles shield the first opening 1132a and avoid the second opening 1132b, so that the airflow inside the main body 11 is blown out from the second opening 1132b. When the wind-blocking rotary cylinder rotates to the second position, the baffles shield the second opening 1132b and avoid the first opening 1132a, so that the airflow inside the main body 11 is blown out from the first opening 1132a. Two types of openings are provided in the housing 115. By avoiding one type of opening and blocking the other, the air outlet parameters can be switched, which helps to simplify the structure.

[0065] In some embodiments, the rotating structure includes a wind-blocking rotary cylinder rotatably assembled to the outer wall of the mounting component 16. The air outlet port 113 includes a first opening 1132a and a second opening 1132b penetrating the side wall of the housing 115, wherein the air outlet area and / or air outlet angle of the first opening 1132a and the second opening 1132b are different. The shielding structure 1141 includes a plurality of baffles disposed on the wind-blocking rotary cylinder. When the wind-blocking rotary cylinder rotates to a first position, the baffles partially shield and partially avoid the first opening 1132a and partially avoid the second opening 1132b, so that the airflow from the air outlet duct blowing out from the first opening 1132a and the second opening 1132b forms a first type of air outlet parameter. When the wind deflector rotates to the second position, the baffle partially blocks and avoids the first opening 1132a and the second opening 1132b, so that the airflow from the outlet duct blows out from the first opening 1132a and the second opening 1132b, forming a second type of airflow parameter. By providing two types of openings in the housing 115, and by partially avoiding one opening and partially blocking the other, the first and second airflow parameters can be switched, which helps to simplify the structure, enrich the airflow parameters, and expand the application scenarios of the hair dryer.

[0066] For example, the wind deflector has 12 baffles evenly distributed at the end near the air outlet. The air outlet port 113 of the head housing 115 adopts a double-layer design, with the inner layer angled towards the center to form a concentrated air duct and the outer layer outward to form a diffused air duct. Furthermore, the inner layer has 12 second openings 1132b and the outer layer has 12 first openings 1132a. In the shaping mode (i.e., the wind deflector is in the first position), the wind deflector is driven to rotate by a motor (or can be driven by other means). The baffles completely cover the outer diffusion holes, and only the inner concentrated air duct is open (i.e., 12 baffles block the first opening 1132a and avoid the second opening 1132b, and the airflow of the outlet air duct blows out from the second opening 1132b). In the drying mode (i.e., the wind deflector is in the second position), after the wind deflector rotates, the baffles cover the inner concentrated holes and the outer diffusion air duct is opened (i.e., 12 baffles block the second opening 1132b and avoid the first opening 1132a, and the airflow of the outlet air duct is discharged from the first opening 1132a).

[0067] Or, such as Figures 11-13 As shown, the main body 11 of the device includes a housing 115 and a fixed ring 117 fixedly assembled to the housing 115. The rotating structure includes a rotating ring 116 located axially inside the fixed ring 117, and the rotating ring 116 is movably assembled to the outer wall of the mounting component 16. The air outlet port 113 includes a third opening 1132c and a fourth opening 1132d provided on the fixed ring 117. The rotating ring 116 has a fifth opening 1161 that matches the structure of the third opening 1132c and a sixth opening 1162 that matches the structure of the fourth opening 1132d. The fixed ring 117 is fixedly assembled to the housing 115. The rotating ring 116 is drivenly connected to the drive mechanism 14 to rotate relative to the fixed ring 117. When the rotating ring 116 is in the third position, the third opening 1132c and the fifth opening 1161 communicate to form a first through hole. The fixed ring 117 blocks the sixth opening 1162, and the rotating ring 116 blocks the fourth opening 1132d, so that the airflow inside the main body 11 is blown out from the first through hole. When the rotating ring 116 is in the fourth position, the fourth opening 1132d and the sixth opening 1162 connect to form a second through hole. The fixed ring 117 blocks the fifth opening 1161, and the rotating ring 116 blocks the third opening 1132c, so that the airflow inside the device body 11 is blown out through the second through hole. The first and second through holes have different air outlet areas and / or air outlet angles. In this embodiment, the rotating ring 116 and the fixed ring 117 are each provided with an opening. The through hole formed by the connection of the openings on the two components during rotation helps to increase the length of the air outlet duct, reduce space occupation, reduce wind resistance, improve structural reliability, and facilitate precise control of the air outlet angle.

[0068] In other embodiments, such as Figure 14 , Figure 15As shown, the movable component 114 includes a guide ring 17 movably assembled to the outer wall of the mounting component 16. The housing 115 and the mounting component 16 form an air outlet port 113. The guide ring 17 includes an outer contour facing the housing 115. The housing 115 includes an inner contour matching the shape of the outer contour. The outer contour includes a first segment 171 and a second segment 172 arranged axially along the guide ring 17. The cross-sectional dimension of the first segment 171 is smaller than that of the second segment 172. The drive mechanism 14 drives the guide ring 17 to move axially to change the air outlet area and / or air outlet angle of the air outlet port 113. The size of the air outlet area of ​​the air outlet port 113 can be changed by using the push-pull operation of the guide ring 17, thereby changing the air outlet parameters and helping to simplify the structural setup.

[0069] Specifically, the front end of the outer casing may be provided with a conical platform that contracts toward the axis of the casing 115. Along the direction of airflow within the casing 115, the outer diameter of the duct ring first expands and then contracts to form an expanding section and a contracting section. The slope of the contracting section is the same as the slope of the conical platform at the front end of the casing 115 to guide the airflow out of the outlet and optimize the airflow effect. The expanding section and the contracting section are smoothly connected to reduce wind resistance, guide the airflow, and reduce air volume loss and noise.

[0070] The outer wall of the mounting component 16 and the inner surface of the guide ring 17 are provided with a guide groove 173 and a guide rib 161, respectively. The guide rib 161 is slidably assembled into the guide groove 173, allowing the guide ring 17 to move along the guide groove 173, improving motion accuracy and reliability, and preventing rotational deviation caused by the up-and-down movement of the guide ring 17, which would generate resistance and affect the overall motion mechanism. Furthermore, the drive mechanism 14 is driven by a motor and includes a third motor 141. The third motor 141 can be mounted and fixed on the mechanism bracket or the outer wall of the mounting component 16. The telescopic arm of the third motor 141 is fixed in the slot of the guide ring 17. When the telescopic arm of the third motor 141 slides along the axial direction of the guide ring 17, it drives the guide ring 17 to move along the aforementioned axial direction, thereby achieving the function of controlling the air duct.

[0071] In some embodiments, the drive mechanism 14 includes a third motor 141 and a connecting member connected to the output end of the third motor 141. A movable member 114 is driven by the connecting member, such that the third motor 141 drives the connecting member to move the movable member 114 relative to the air outlet 113. Driving the connecting member with the third motor 141 helps simplify the drive mechanism 14 and its control logic.

[0072] In the above embodiments, such as Figure 3 As shown, Figure 3The double-dotted line in the diagram can represent the axial direction of the main body 11. When the drive mechanism 14 is driven by a motor, the connecting components include a first connector 142. One of the first connector 142 and the movable component 114 is provided with a slide groove 1142 that is inclined relative to the axial direction of the main body 11, and the other is provided with a slider 1421. The slider 1421 is slidably assembled in the slide groove 1142. The movement of the slider 1421 along the slide groove 1142 can drive the movable component 114 to move relative to the air outlet 113. The movable component 114 is driven by the slider 1421 and the inclined slide groove 1142, which reduces the transmission structure and reduces the space occupied by the drive mechanism 14.

[0073] Or, such as Figure 14 As shown, the connecting component includes a second connector 143, which is connected to the output end of the third motor 141 and the guide ring 17. The third motor 141 drives the second connector 143 to move axially, and the second connector 143 drives the guide ring 17 to move axially relative to the air outlet 113. The transmission between the third motor 141 and the movable component 114 is directly achieved through the second connector 143, which helps to reduce the complexity of the transmission structure and improve the reliability of the transmission structure. In some embodiments, the third motor 141 is a stepper motor, the second connector 143 is provided with a slot, and the third motor 141 has a transmission arm, which is fixedly connected to the second connector 143 through the aforementioned slot.

[0074] Or, such as Figure 16 As shown, the connecting component includes a gear assembly 144. The output end of the third motor 141 meshes with the input gear of the gear assembly 144, and the output gear of the gear assembly 144 meshes with the movable component 114. Based on the meshing transmission between the gears within the gear assembly 144, the meshing transmission between the input gear and the third motor 141, and the meshing transmission between the output gear and the movable component 114, the movable component drives the movable component 114 to move relative to the air outlet 113. Gear transmission helps improve transmission reliability. The gear assembly 144 can be a transmission mechanism formed by a micro-gear set, or a transmission mechanism formed by the meshing of a gear and a rack.

[0075] It should be noted that the hair dryer 1 can be a single air duct or multiple air ducts. When the hair dryer 1 is a single air duct, the movable part 114 is movably assembled in the air outlet duct. When the hair dryer 1 includes multiple air ducts, the movable part 114 can be movably assembled in at least one air outlet duct.

[0076] In some embodiments, the hair dryer 1 further includes a first motor 12, a second motor 13, and a heating element 15. The air outlet duct includes a first air duct 111 and a second air duct 112, and the air outlet port 113 includes a second air outlet 1132 communicating with the second air duct 112. The first motor 12 and the heating element 15 are assembled in the first air duct 111, and the control board 20 of the device body 11 is electrically connected to the first motor 12 and the heating element 15, respectively. The second motor 13 is assembled in the second air duct 112, and the control board 20 of the device body 11 is electrically connected to the second motor 13. The control board 20 can send drive control signals to at least one of the first motor 12, the second motor 13, and the heating element 15 according to control logic to make the hair dryer 1 operate according to target parameters. The first motor 12 and the heating element 15 are located in the first air duct 111, and the second motor 13 is located in the second air duct 112. This ensures that the heat from the heating element 15 has no effect on the air temperature in the second air duct 112, thus helping to achieve decoupled control of air volume and air temperature and improving the control flexibility and accuracy of the air outlet parameters.

[0077] Furthermore, when the aforementioned drive mechanism 14 includes the aforementioned third motor 141, the control motherboard 20 can send drive control signals to at least one of the first motor 12, the second motor 13, the third motor 141, and the heating element 15 according to control logic, so that the blower 1 operates according to the target parameters. The first motor 12 and the heating element 15 are located in the first air duct 111, and the second motor 13 is located in the second air duct 112. The heat from the heating element 15 has no effect on the air temperature in the second air duct 112, and the third motor 141, by driving the movable part 114, can change the air outlet parameters of the air outlet port 113, further altering the air volume and airflow pattern. Therefore, not only can decoupled control of air volume and air temperature be achieved, but the control flexibility and accuracy of the air outlet parameters can also be further improved.

[0078] In the above embodiments, such as Figure 1 , Figure 2 As shown, the air outlet 113 includes a second air outlet 1132 connected to the second air duct 112, and the main body 11 of the device also includes a first air outlet 1131 connected to the first air duct 111. The second air outlet 1132 is located around the first air outlet 1131 in the circumferential direction. The airflow pattern can be optimized by using the positions of the first air outlet 1131 and the second air outlet 1132. By controlling the airflow angle of the second air outlet 1132, a converging airflow pattern and a diffusing airflow pattern can be obtained.

[0079] In some embodiments, the device body 11 includes a distance sensor for detecting the sensing distance from the distance sensor to the surface to be blown. The control board 20 of the device body 11 is electrically connected to the distance sensor to adjust at least one of the air temperature and air volume of the hair dryer 1 according to the sensing distance. The control signal of the hair dryer 1 to the drive mechanism 14 can be associated with the sensing distance between the hair dryer 1 and the surface to be blown, so that the hair dryer 1 can adjust at least one of the air temperature and air volume according to the sensing distance.

[0080] When the hair dryer 1 includes a first motor 12, a second motor 13, and a heating element 15, and the drive mechanism 14 includes a third motor 141, the control signals of the hair dryer 1 to the first motor 12, the second motor 13, the third motor 141, and the heating element 15 can be correlated with the sensing distance between the hair dryer 1 and the surface to be blown. This allows the hair dryer to operate at a low temperature when the sensing distance is less than a first value, and at a high temperature when the sensing distance is greater than a second value, thereby ensuring blowing efficiency while avoiding burns. In some embodiments, a low temperature can be achieved by reducing the power of the heating element 15, reducing the speed of the first motor 12, and increasing the speed of the second motor 13. Those skilled in the art can select one or more of the aforementioned combinations as needed to achieve a low temperature. A high temperature can be achieved by increasing the power of the heating element 15, increasing the speed of the first motor 12, and reducing the speed of the second motor 13. Those skilled in the art can select one or more of the aforementioned combinations as needed to achieve a high temperature.

[0081] Furthermore, based on the correlation control between the sensing distance and the first motor 12, the second motor 13, and the third motor 141, airflow parameters such as air volume, air velocity, and airflow pattern can also be correlated with the sensing distance. For example, when the sensing distance is less than a first value, the airflow pattern switches to a diffusion type, driving the third motor 141 to increase the airflow volume and airflow angle at the air outlet 113 to obtain a large airflow and low air temperature. When the sensing distance is greater than the first value, the airflow pattern switches to a converging type, driving the third motor 141 to decrease the airflow volume and airflow angle at the air outlet 113 to obtain a high air velocity and high air temperature.

[0082] Furthermore, when the wind speed setting is fixed, the wind speed does not change with the sensing distance. When the wind speed changes due to adjustments in wind temperature and airflow based on the sensing distance, a stable wind speed can be obtained at different sensing distances by controlling the speed increases or decreases of the first motor 12 and the second motor 13. Alternatively, when the wind speed setting is unrestricted, the speed increases or decreases of the first motor 12 and the second motor 13 can be controlled according to the sensing distance to reduce the wind speed when the sensing distance is less than a first value and increase the wind speed when the sensing distance is greater than a second value.

[0083] It should be noted that the sensing distance when the user is using the hair dryer 1 normally can be set to a set value or a set range. The first value can be any value less than or equal to the set value, and the second value can be any value greater than or equal to the set value. Alternatively, the first value can be any value less than or equal to the minimum value of the set range, and the second value can be any value greater than or equal to the maximum value of the set range.

[0084] In the above embodiment, a distance sensor can be assembled at the air outlet 113 to facilitate the measurement of the distance between the air outlet 113 and the surface to be ventilated. The distance sensor can be a TOF (Time of Flight) sensor or an infrared sensor. Furthermore, the air outlet 113 is annular, and the distance sensor is disposed radially inside the air outlet 113 to prevent heat from affecting the reliability of the distance sensor's operation.

[0085] In some embodiments, the main body 11 of the device may also include a heat insulation cylinder, which is used to isolate the heat transfer between the heating element 15 and the second air duct 112. The distance sensor is assembled in the heat insulation cylinder to avoid the influence of the heating element 15 on the distance sensor.

[0086] In some embodiments, the hair dryer 1 includes a head 18 and a grip 19, the grip 19 being assembled below the head 18, an air outlet 113 being disposed on the head 18, a first motor 12 and a heating element 15 being assembled inside the head 18, and a second motor 13 being assembled inside the grip 19, to form a structurally optimized hair dryer 1 as a whole.

[0087] In the above embodiments, the mounting component 16 may include a heat insulation cylinder assembled within the housing 115. The existing heat insulation cylinder structure within the blower 1, in conjunction with the housing 115, forms an air outlet duct, which helps reduce the structural cost and space occupation caused by additional structural elements. It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
