[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] This utility model embodiment provides a hair dryer 100, such as Figures 1 to 4 As shown, the hair dryer 100 includes a head 1, a handle 2, a mounting bracket 3, a functional module 4, and a battery 5. The head 1 has an air inlet 11 at one end and an air outlet 12 at the other end. A blower assembly 13 is located inside the head 1, between the air inlet 11 and the air outlet 12. The handle 2 is connected to the head 1. The mounting bracket 3 is detachably mounted inside the handle 2 near the head 1. The functional module 4 includes a display module 41 and a control module 42, both mounted on the mounting bracket 3. The battery 5 is located inside the handle 2. When the mounting bracket 3 is mounted inside the handle 2, it secures the battery 5 between the mounting bracket 3 and the handle 2, while the display module 41 is visible outside the handle 2.

[0020] Specifically, the head unit 1 has an air inlet 11 at one end and an air outlet 12 at the other end. An air blowing assembly 13 is located inside the head unit 1, between the air inlet 11 and the air outlet 12. The air blowing assembly 13 draws air from outside the air inlet 11 into the head unit 1 and blows it out from the air outlet 12 to form an airflow. The air blowing assembly 13 consists of a motor and a fan wheel, which are conventional in the art and will not be described in detail here.

[0021] The handle 2 is connected to the head 1. A mounting bracket 3 is detachably installed inside the end of the handle 2 near the head 1. Both the display module 41 and the control module 42 are mounted on the mounting bracket 3. Therefore, during assembly, the display module 41 and control module 42 can be pre-assembled onto the mounting bracket 3 outside the handle 2 to form an assembly unit. Then, the mounting bracket 3 is assembled into the end of the handle 2 near the head 1, thus securing the display module 41 and control module 42. The mounting bracket 3 also limits the battery 5 between the mounting bracket 3 and the handle 2. Therefore, the hair dryer 100 of this invention avoids directly installing the display module 41 and control module 42 inside the handle 2, effectively reducing the difficulty of installing the display module 41 and control module 42 and improving assembly efficiency.

[0022] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 4 As shown, the outer wall of the mounting bracket 3 is provided with a fixing block 31, and the inner wall of the handle 2 near the end of the machine head 1 is provided with a fixing groove 21. The fixing block 31 is accommodated in the fixing groove 21 to fix the mounting bracket 3.

[0023] Specifically, the outer wall of the mounting bracket 3 is provided with a fixing block 31, and the inner wall of the handle 2 near the head 1 is provided with a fixing groove 21. When the display module 41 and the control module 42 are assembled on the mounting bracket 3, and the mounting bracket 3 is placed into the handle 2 near the head 1, the fixing block 31 can simultaneously snap into the fixing groove 21, thereby fixing the mounting bracket 3 in the handle 2. Furthermore, during disassembly, simply pull the mounting bracket 3 outwards from the handle 2, and the fixing block 31 can disengage from the fixing groove 21, thus removing the mounting bracket 3 from the handle 2. The design of the fixing block 31 and the fixing groove 21 allows for convenient assembly and disassembly of the mounting bracket 3, effectively improving assembly efficiency.

[0024] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 4 As shown, the fixing block 31 is located at the junction of two adjacent outer side walls on the mounting bracket 3, and the fixing groove 21 is located at the junction of two adjacent inner side walls on the handle 2.

[0025] Specifically, by placing the fixing block 31 at the junction of two adjacent outer walls on the mounting frame 3, the corner positions at the junction of the two adjacent outer walls of the mounting frame 3 can be effectively utilized, thereby avoiding the fixing block 31 occupying too much assembly space on the mounting frame 3, leaving more room for the layout of the display module 41, control module 42, and battery 5, effectively improving space utilization and facilitating the miniaturization of the mounting frame 3.

[0026] It is worth mentioning that the joints between two adjacent side walls on the mounting bracket 3 and the joints between two adjacent inner side walls on the handle 2 are rounded. This serves two purposes: firstly, it provides guidance when assembling the mounting bracket 3, allowing the fixing block 31 to fit more smoothly into the fixing groove 21; secondly, it avoids sharp edges at the joints between two adjacent inner side walls on the handle 2, increasing the user's grip comfort and feel.

[0027] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 3 As shown, the side wall of the machine head 1 is provided with a connecting arm 14. The side wall of the connecting arm 14 is connected to the end of the handle 2 near the machine head 1, and the bottom wall of the connecting arm 14 abuts against the fixing block 31 to limit the fixing block 31 within the fixing groove 21.

[0028] Specifically, the side wall of the machine head 1 is provided with a connecting arm 14. When the mounting bracket 3 is assembled into the handle 2, the end of the handle 2 near the machine head 1 can be connected to the side wall of the connecting arm 14. At the same time, the bottom wall of the connecting arm 14 can abut against the fixing block 31, thereby limiting the fixing block 31 in the fixing groove 21 to prevent the fixing block 31 from accidentally falling out of the fixing groove 21 and ensuring the stability of the mounting bracket 3 installation.

[0029] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 4 As shown, the side wall of the connecting arm 14 is provided with a buckle hole 15, and the inner side wall of the handle 2 near the end of the machine head 1 is provided with a buckle 22, which is detachably fastened to the buckle hole 15.

[0030] Specifically, the side wall of the connecting arm 14 is provided with a snap hole 15, and the inner side wall of the handle 2 near the end of the machine head 1 is provided with a buckle 22. Thus, when the end of the handle 2 near the machine head 1 is fitted over the side wall of the connecting arm 14, the buckle 22 can engage with the snap hole 15, thereby connecting the handle 2 to the connecting arm 14 of the machine head 1. Furthermore, the detachable snap-fit ​​design makes the installation and removal of the machine head 1 and the handle 2 simple and quick.

[0031] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 2 As shown, the handle 2 is provided with a heat dissipation hole 23, which is located at the end of the handle 2 away from the head 1.

[0032] Specifically, the handle 2 is provided with a heat dissipation hole 23, which is located at the end of the handle 2 away from the head 1. The heat dissipation hole 23 provides an effective heat dissipation channel for the battery 5 inside the handle 2. Through the heat dissipation hole 23, the heat generated by the battery 5 during operation can be quickly dissipated to the external environment, preventing heat from accumulating inside the handle 2.

[0033] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 3 As shown, three of the four side walls of the mounting bracket 3 are provided with a first mounting groove 32, and the other is provided with a second mounting groove 33. The side wall of the handle 2 opposite to the first mounting groove 32 is provided with an opening 24. The control module 42 includes a main control module 421, a wind adjustment module 422, and an interface module 423. The display module 41, the wind adjustment module 422, and the charging module are respectively installed in a first mounting groove 32 and exposed to the outside of the handle 2 through the opening 24. The main control module 421 is installed in the second mounting groove 33 and is connected to the blower assembly 13, the display module 41, the wind adjustment module 422, the interface module 423, and the battery 5.

[0034] Specifically, three of the four side walls of the mounting bracket 3 are provided with a first mounting slot 32, and the other is provided with a second mounting slot 33. The control module 42 includes a main control module 421, an air conditioning module 422, and an interface module 423. By splitting the control module 42 into the main control module 421, the air conditioning module 422, and the interface module 423, the display module 41, the air conditioning module 422, and the charging module can be installed in the first mounting slot 32 respectively, and the main control module 421 can be installed in the second mounting slot 33. This improves the space utilization of the mounting bracket 3, allowing the mounting bracket 3, the display module 41, and the control module 42 to be compactly arranged, reducing the space occupied by the mounting bracket 3, the display module 41, and the control module 42, and helping to reduce the size of the handle 2. In addition, after splitting the control module 42 into the main control module 421, the air conditioning module 422, and the interface module 423, when a fault occurs, the faulty module can be accurately located and only that module can be replaced, without replacing the entire control module 42, which helps to reduce maintenance costs.

[0035] More specifically, the main control module 421 is equipped with a main control MCU (Microcontroller Unit), which is electrically connected to the display module 41, the air conditioning module 422, and the interface module 423 to control their operation. The display module 41 is equipped with a display screen 411 and a first button 412, both of which are exposed on the handle 2 through the port 24. This allows the display screen 411 to display the real-time operating status of the hair dryer 100, such as airflow level and battery level, enabling the user to monitor the device's operation at any time. The first button 412 allows the display module 41 to be turned on or off at any time, saving power. The interface module 423 is equipped with a charging interface 4231 and a second button 4232, and is electrically connected to the battery 5 to charge the battery 5. The second button 4232 is the main switch of the hair dryer 100, which can control the overall opening and closing of the hair dryer 100. The second button 4232 is exposed on the handle 2 through the port 24 for easy operation. The air conditioning module 422 is equipped with an air conditioning knob 4221 and a third button 4222, and is connected to the blower assembly 13. The air conditioning knob 4221 is a stepless adjustment knob, which can smoothly and continuously adjust the airflow generated by the blower assembly 13, instead of switching between a limited number of levels (such as low, medium, and high), thus achieving stepless air conditioning function. The third button 4222 can control the opening and closing of the blower assembly 13. Both the air conditioning knob 4221 and the third button 4222 are exposed on the handle 2 through the port 24 for easy operation.

[0036] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 3 As shown, the mounting bracket 3 is provided with a hollow cavity 34, which is connected to the first mounting groove 32, the second mounting groove 33 and both ends of the mounting bracket 3.

[0037] Specifically, the mounting bracket 3 is provided with a hollow cavity 34, which is connected to the first mounting groove 32, the second mounting groove 33 and both ends of the mounting bracket 3. Thus, the blower assembly 13, main control module 421, air adjustment module 422, interface module 423, display module 41 and battery 5 inside the blower 100 can be wired through the hollow cavity 34. This reduces the difficulty of wiring and makes the wiring more neat and orderly, avoiding the mess of cables.

[0038] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 3 As shown, the display module 41 is located in the first mounting slot 32, which is opposite to the second mounting slot 33.

[0039] Specifically, the display module 41 is located in the first mounting slot 32 opposite to the second mounting slot 33, meaning the air conditioning module 422 and the interface module 423 can be located on both sides of the display module 41. Since the user typically holds the handle 2 with the side containing the display module 41 facing outwards, this embodiment ensures that the first button 412 of the display module 41, the wind knob and third button 4222 of the air conditioning module 422, and the second button 4232 of the interface module 423 are all within the user's thumb and forefinger's operating range. This allows the user to quickly and conveniently control different buttons with one hand, whether before or during use.

[0040] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 3 As shown, the hair dryer 100 also includes three protective covers 6, which are detachably installed at the three openings 24.

[0041] Specifically, three protective covers 6 are detachably installed at the three openings 24, thus covering the display module 41, the air conditioning module 422, and the interface module 423. This protects the display module 41, the air conditioning module 422, and the interface module 423 from damage due to accidental collisions or drops, and also enhances the overall aesthetics of the hair dryer 100. The area of ​​the protective cover 6 covering the display module 41 corresponding to the display screen 411 is transparent, allowing the information on the display screen 411 to be viewed. Furthermore, the first button 412, the air conditioning knob 4221, the third button 4222, and the charging interface 4231 are all exposed outside the protective cover 6 for easy operation.

[0042] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
