[0125] It should be noted that the "total lumen value", "total rated power" and "total color temperature" here refer to the total value output by the lighting device 600, that is, when the lighting device 600 includes multiple light-emitting units 614, the total lumen value refers to the sum of the lumen values ​​output by all the light-emitting units 614, the total rated power refers to the sum of the rated powers of all the light-emitting units 614, and the total color temperature refers to the sum of the color temperatures of all the light-emitting units 614. The lumen value refers to the luminous flux value of the rated output of the light-emitting unit 614, which is also the nominal luminous flux value of the light-emitting unit 614. For the light-emitting unit 614, the lumen value of the light-emitting unit can also be defined as follows: the lumen value obtained by measuring at a position 50 cm away from the light-emitting direction of the light-emitting unit 614 is the lumen value of the light-emitting unit 614. For a lighting device 600 composed of multiple light-emitting units 614, the total lumen value of the lighting device 600 can be obtained by measuring at a position 50 cm away from the lighting device.

[0126] The following discusses the case where the lighting device 600 includes a plurality of light-emitting units 614. In some embodiments, the lumen value of each light-emitting unit 614 may be greater than or equal to 100 lm, and the specific lumen value of the light-emitting unit 614 may be: 120 lm, 140 lm, 150 lm, 160 lm, 180 lm, etc. In one embodiment, the rated power range of the light-emitting unit 614 is about 0.9 W. In some embodiments, the specific rated power of the light-emitting unit 614 may be: 0.9 W, 1.1 W, 1.3 W, etc. In one embodiment, the color temperature range of the light-emitting unit 614 is about 4000 K, 4500 K, or 5000 K.

[0127] In one embodiment, the lighting device 600 includes six light-emitting units 614 , and the total rated power formed by the six light-emitting units 614 is 5.4 W, and the total lumen value is about 900 lm.

[0128] In some embodiments, the lighting device 600 is connected to the control component 720 for communication, so that the light-emitting portion 614 can be turned off after the preset time when the motor stops rotating, that is, the lighting device 600 is intelligently turned off, thereby improving the user experience. Optionally, the preset time can be 3s, 5s, 7s, etc., which is not specifically limited here. In some embodiments, the user can set the lighting device 600 to select an appropriate preset time.

[0129] In some embodiments, the light-emitting unit 614 can emit light of at least two colors. Optionally, the light-emitting unit 614 can emit white light, which has better brightness and is suitable for use in normal weather. The light-emitting unit 614 can emit yellow light, which has stronger penetration and is more suitable for use in foggy days. Optionally, the light-emitting unit 614 can emit red light. When working under complex construction conditions, turning on the red light can serve as a warning to the outside world. In other embodiments, the colors emitted by the light-emitting unit 614 are not limited to the above colors. Optionally, the lighting device 600 may include at least two light-emitting units 615, each of which emits light of one color.

[0130] In some embodiments, the light-emitting unit 614 can provide safety indications, fault indications, and battery level reminders of the battery pack 130. Optionally, the light-emitting unit 614 can flash at different frequencies, and indicate safety indications, fault indications, and battery level reminders at different flashing frequencies. It is understandable that the light-emitting unit 614 can also indicate safety indications, fault indications, and battery level reminders by emitting light of different colors. Optionally, the light-emitting unit 614 can also project an image, which can be a brand logo, model, etc. of the product, so as to achieve a certain advertising effect.

[0131] In some embodiments, the lighting device 600 includes at least two light-emitting units 614. At least two light-emitting units 614 can be turned on separately. Optionally, one of the light-emitting units 614 can be set to a low-beam mode, and one of the light-emitting units 614 can be set to a high-beam mode, so as to meet different usage requirements. Of course, the two light-emitting units 614 can also be started at the same time, so that the lighting device 600 has a higher intensity and a larger illumination range. It should be noted that the low-beam mode and the high-beam mode are collectively referred to as the light-emitting mode of the light-emitting unit 614. Optionally, different light-emitting units 614 can be set at different positions of the hair dryer 10, so that the lighting device 600 can illuminate the front of the hair dryer 10 while also illuminating the side and rear of the hair dryer 10, thereby preventing the user from falling and bumping due to not being able to see the road surface clearly.

[0132] In this embodiment, Figure 1 and Figure 4As shown, the lighting device 600 also includes a switch assembly 620, which is used to control the working state of the light assembly 610. It is understandable that the control of the light assembly 610 by the switch assembly 620 includes but is not limited to turning on and off the light-emitting portion 614, adjusting the brightness of the light-emitting portion 614, selecting the light color of the light-emitting portion 614, triggering the projection of the light-emitting portion 614, selecting the light-emitting mode of the light-emitting portion 614, and adjusting the stroboscopic frequency of the light-emitting portion 614. In one embodiment, the maximum distance between the switch assembly 620 and the light-emitting portion 614 is less than or equal to 5 cm, so that the length of the cable connected between the switch assembly 620 and the light-emitting portion 614 can be shortened, thereby making the cables inside the hair dryer 10 neat and not easily damaged. For the embodiment in which the lighting device 600 is installed on the operating handle 910, the switch assembly 620 can also be located on the operating handle 910.

[0133] It should be noted that the lighting device 600 may also include only the lamp assembly 610 but not the switch assembly 620. Here, “not including the switch assembly 620” means not including the lamp assembly 610. Figure 1 The physical structure of the switch assembly 620 shown. In some embodiments, the lighting device 600 also includes a communication module, and the user can communicate with the communication module through a terminal setting such as a mobile phone, so as to control the light assembly 610. Optionally, the communication module can be a Bluetooth module, a wifi module, etc. In some embodiments, the lighting device 600 can be provided with a light sensing device, and when the ambient brightness is reduced to a threshold value and is recognized by the light sensing device, the light assembly 610 automatically lights up. In some embodiments, the switch assembly 620 can also be combined with the structure of other switches of the hair dryer 10.

[0134] In some embodiments, such as Figure 1 As shown, the light assembly 610 is disposed on the front side of the handle 400 , thereby preventing the handle 400 from blocking the light of the light assembly 610 .

[0135] like Figure 3 and Figure 4As shown, the lamp assembly 610 is connected to the housing 100, and the lamp assembly 610 is arranged toward the front side of the hair dryer 10, while the switch assembly 620 is arranged toward the top of the hair dryer 10, so that the user can see the switch assembly 620 and operate it. The switch assembly 620 includes a button 621, a pivot shaft 624, an elastic member 622 and a first circuit board 623. The button 621 is pivoted to the housing 100 through the pivot shaft 624, and the axis of the pivot shaft 624 is the pivot axis 625. The first circuit board 623 is arranged opposite to the button 621, and the first circuit board 623 is electrically connected to the lamp assembly 610, and the elastic member 622 is arranged between the button 621 and the housing 100. When the user presses the button 621, the button 621 rotates around the pivot axis 625 and approaches the first circuit board 623, thereby triggering the electrical components on the first circuit board 623, and then the lamp assembly 610 is lit. When the user releases the button 621, the elastic member 622 resets the button 621. In some embodiments, a mechanical switch is provided on the first circuit board 623, and when the button 621 is reset, the mechanical switch is disconnected, and the corresponding lamp assembly 610 is turned off. In some embodiments, an electronic switch 640 is provided on the first circuit board 623, and when the button 621 is reset, the lamp assembly 610 is not turned off, and the user needs to press the button 621 again to turn off the lamp assembly 610.

[0136] like Figure 5 As shown, the lamp assembly 610 includes a second circuit board 611, which is electrically connected to the first circuit board 623, and a light-emitting portion 614 is arranged on the second circuit board 611. When the first circuit board 623 is triggered by the button 621, the second circuit board 611 turns on or off the light-emitting portion 614. In one embodiment, the light-emitting portion 614 can be a lamp. The lamp assembly 610 also includes a light-guiding portion 612 and a light-transmitting portion 613. The light-guiding portion 612 is arranged on the front side of the second circuit board 611, and a light-guiding channel is arranged on the light-guiding portion 612. The light-emitting portion 614 at least partially extends into the light-guiding channel, thereby limiting the light direction of the light-emitting portion 614. The light-transmitting portion 613 is covered on the front side of the second circuit board 611, thereby protecting the second circuit board 611, the light-emitting portion 614, and the light-guiding portion 612, and ensuring that the light of the light-emitting portion 614 can be transmitted.

[0137] In some embodiments, Figure 6 As shown, the switch assembly 620 and the light assembly 610 are integrated into one body, thereby making the appearance of the hair dryer 10 more concise and beautiful.

[0138] like Figure 6 and Figure 7As shown, the integrated structure of the switch assembly 620 and the lamp assembly 610 is arranged toward the front side of the hair dryer 10, so as to illuminate the working environment in front of the hair dryer 10. The lighting device 600 includes a third circuit board 630 and a button 621 arranged opposite to the third circuit board 630, the light-emitting portion 614 is arranged on the third circuit board 630, and the third circuit board 630 is also provided with an electronic switch 640. In some embodiments, when the user presses the button 621, the button 621 triggers the electronic switch 640, and the third circuit board 630 lights up the light-emitting portion 614. When the user presses the button 621 again, the electronic switch 640 is turned off, and the light-emitting portion 614 is correspondingly turned off. In some embodiments, the light-emitting portion 614 has at least two brightnesses. When the user presses the button 621 for the first time, the light-emitting portion 614 emits light of a first brightness, when the user presses the button 621 for the second time, the light-emitting portion 614 emits light of a second brightness, and when the user presses the button 621 for the third time, the light-emitting portion 614 is turned off.

[0139] like Figure 7 As shown, the lighting device 600 further includes a light guide portion 612 and a light transmissive portion 613. The light guide portion 612 is arranged at the front side of the third circuit board 630. A light guide channel is formed on the light guide portion 612. At least part of the light emitting portion 614 is located in the light guide channel. The light guide portion 612 guides the light emitted by the light emitting portion 614. The light transmissive portion 613 is arranged at the front side of the light guide portion 612. The light transmissive portion 613 can protect the third circuit board 630, the light emitting portion 614, and the light guide portion 612, and ensure that the light of the light emitting portion 614 can be transmitted. In this embodiment, the button 621 is movably connected to the light transmissive portion 613, so that the light transmissive portion 613 supports the button 621.

[0140] like Figure 8 As shown, the hair dryer 10 has a hair dryer axis 101, and the hair dryer axis 101 is colinear with the axis of the duct assembly 260 (that is, the axis of the wind tube 270). Similarly, the hair dryer axis 101 can also be the axis of the wind tube 270. The front end 104 of the hair dryer refers to the top of the front side of the wind tube 270 near the edge of the air outlet, and the geometric center 103 of the lamp assembly 610 refers to the geometric center of the largest luminous plane of the lighting device 600 for lighting. When the hair dryer 10 is working, the angle α between the hair dryer axis 101 and the ground is 25 degrees to 40 degrees. The first length S1 is defined as the length of the projection of the line connecting the front end 104 of the hair dryer 10 and the geometric center 103 of the lamp assembly 610 on the ground, and the first length S1 is greater than or equal to 1m. In some embodiments, the first length S1 is greater than or equal to 1.5m. In some embodiments, the first length S1 is greater than or equal to 2m. It can be understood that those skilled in the art can select a lamp assembly 610 with corresponding performance according to the actual needs of the first length S1.

[0141] In other words, the hair dryer also includes a lighting device, which includes a light-emitting portion. When the angle α between the axis of the hair dryer and the blown surface is 30 degrees, and the minimum distance H from the air outlet to the blown surface is 15 cm, the illuminance of the light generated by the lighting device is greater than or equal to 50 lux when measured along the front of the hair dryer at a distance of 1 m from the front end of the air outlet on the blown surface. In one embodiment, the illuminance of the light generated by the lighting device at this position is greater than or equal to 70 lux. In one embodiment, the illuminance of the light generated by the lighting device at this position is greater than or equal to 100 lux.

[0142] In one embodiment, the illuminance of the light generated by the lighting device is greater than or equal to 50 lux, measured along the rear of the hair dryer, on the blown surface at 0.5 m from the front end of the air outlet. In one embodiment, the illuminance of the light generated by the lighting device is greater than or equal to 100 lux, measured along the rear of the hair dryer, on the blown surface at 0.5 m from the front end of the air outlet.

[0143] like Figure 8 As shown, S2 is the distance between the lamp assembly 610 and the front end of the hair dryer 10 along the direction of the hair dryer axis 101, and S3 is the length of the hair dryer 10 along the direction of the hair dryer axis 101. S2 / S3 is less than or equal to 0.8. By setting S2 / S3 in this ratio range, while ensuring that the lamp assembly 610 is easy to install, the position of the lamp assembly 610 is avoided from being too far back, thereby avoiding the lamp assembly 610 from being blocked by the wind tube 270 and creating a large shadow area on the ground, thereby improving the user experience. In one embodiment, S2 / S3 is less than or equal to 0.7. In some embodiments, S2 / S3 is approximately 0.55 or 0.45.

[0144] The second length S4 is defined as the length of the projection on the ground of the line connecting the front end of the hair dryer and the nearest end of the light emitting part that can be irradiated on the ground when the hair dryer is working, and the second length S4 is greater than or equal to 0.5m. As an optional solution, the second length S4 is greater than or equal to 1m.

[0145] In some embodiments, such as Fig. 9 As shown, the lamp assembly 610 is disposed at the air outlet of the air cylinder 270. Therefore, other components of the hair dryer 10 will not block the light of the light emitting portion 614, and the lighting effect is better.

[0146] Alternatively, if Fig.10As shown, the lamp assembly 610 includes a second circuit board 611 and a light-emitting portion 614. The second circuit board 611 is annular and fixed at the air outlet of the wind tube 270. In this embodiment, a plurality of light-emitting portions 614 are provided, and the plurality of light-emitting portions 614 are arranged at intervals on the second circuit board 611, and the plurality of light-emitting portions 614 are arranged to form a ring, so that the light emitted by the lamp assembly 610 in all directions is uniform. In some embodiments, the plurality of light-emitting portions 614 can also be arranged to form a complete ring. It should be noted that the complete ring refers to the plurality of light-emitting portions 614 being connected end to end in the circumferential direction. In some embodiments, the light-emitting portion 614 can also be provided as one, and the light-emitting portion 614 is constructed as a complete ring, thereby further improving the uniformity of the light. In this embodiment, the lamp assembly 610 also includes a light-transmitting portion 613, and the light-transmitting portion 613 covers the light-emitting portion 614. The light-transmitting portion 613 can not only ensure that the light is smoothly transmitted, but also protect the light-emitting portion 614, thereby reducing the risk of damage to the light-emitting portion 614.

[0147] In this embodiment, since the lighting power supply / battery pack 130 and the switch assembly 620 are arranged at the housing 100, the lamp assembly 610 and the lighting power supply / battery pack 130, and the lamp assembly 610 and the switch assembly 620 are connected by cables. Fig.11 As shown, a cable housing 271 is constructed on the wind tube 270, and a channel is formed in the cable housing 271 for the cable of the lighting device 600 to pass through. That is, the cable led out of the lamp assembly 610 passes through the cable channel and enters the housing 100, and then is connected to the lighting power supply / battery pack 130, the switch assembly 620, etc., avoiding the cable from being exposed, and improving the aesthetics of the hair dryer 10. In this embodiment, the cable housing 271 extends along the axial direction of the wind tube 270. Optionally, the cable housing 271 and the wind tube 270 are integrally formed.

[0148] In this embodiment, Fig.12 and Fig.13 As shown, the air cylinder 270 is detachably connected to the housing 100, and the hair dryer 10 further includes a coupling mechanism 650, which includes a terminal 651 and a terminal coupling portion 652. The terminal 651 is connected to the air cylinder 270, and the cable in the cable housing 271 is electrically connected to the terminal 651. The terminal coupling portion 652 is connected to the housing 100, and the lighting power supply / battery pack 130 and the switch assembly 620 are electrically connected to the terminal coupling portion 652. After the air cylinder 270 is connected to the housing 100, the terminal 651 and the terminal coupling portion 652 are plugged and matched, thereby realizing the electrical connection between the terminal 651 and the terminal coupling portion 652, and then realizing the electrical connection between the lamp assembly 610 and the lighting power supply / battery pack 130 and the switch assembly 620 respectively. By providing the coupling mechanism 650, this embodiment can avoid pulling the cable apart when disassembling the air cylinder 270, thereby improving the convenience of disassembly and assembly of the hair dryer 10.

[0149] It is understandable that, without violating the concept of the present application, the terminal 651 and the terminal combination portion 652 can be any existing one. In this embodiment, the end of the housing 100 close to the wind tube 270 is provided with a first limit portion 140, and the first limit portion 140 can be configured as a groove, and the terminal combination portion 652 is fixed in the groove. The end of the cable housing 271 close to the housing 100 is provided with a second limit portion 272, and the second limit portion 272 is configured as a groove, and the terminal 651 is fixed in the groove.

[0150] In some embodiments, such as Fig.14 and Fig.15 As shown, the light emitting portion 614 is at least partially disposed on the outer wall of the wind tube 270. Compared with the solution of directly disposing the light emitting portion 614 at the end of the wind tube 270, the light emitting portion 614 disposed on the outer wall of the wind tube 270 is not easily damaged by bumps. In this embodiment, the lamp assembly 610 is constructed in an annular shape and is sleeved on the wind tube 270, which improves the aesthetics of the hair dryer 10. In this embodiment, the wind tube 270 is also provided with a cable housing 271 for the cable of the lighting device 600 to pass through and the above-mentioned coupling mechanism 650. The specific details of the cable housing 271 and the coupling mechanism 650 are the same as those in the previous embodiment and are not repeated here.

[0151] like Fig.15 As shown, along the axis direction of the wind tube 270, the distance between the lighting device and the air outlet of the wind tube 270 is L0, and L0 is less than or equal to 900 lm. The wind tube 270 is usually detachably connected to the housing 100 so that the user can replace different types of wind tubes 270. The wind tube length L1 is defined as the length of the wind tube 270 along the axis of the hair dryer, and the ratio of L0 to L1 is L0 / L1 greater than or equal to 0 and less than or equal to 1. The ratio of the distance L0 between the lighting device and the air outlet of the wind tube 270 to the distance L2 from the wind tube 270 to the center of the trigger is greater than or equal to 0 and less than or equal to 0.7.

[0152] like Fig.16 As shown, when viewed downward from directly above the hair dryer 10, the light-emitting area of ​​the light-emitting portion 614 is basically conical, and the angle between the cone's generatrix 660 and the cone's rotation axis 670 is β, which is greater than or equal to 0° and less than or equal to 60°. Within this range, it can be ensured that at least the blowing area of ​​the hair dryer 10 can be illuminated. Optionally, the value range of β can be 0° to 60°, 10° to 50°, 15° to 45°, or 15° to 30°.

[0153] Combination Figures 1 to 16The hair dryer 10 includes an air inlet 111 and an air outlet 112. The air inlet 111 is covered by an air inlet cover 113. The air flow flows in from the air inlet 111, flows through the duct assembly 260, and is accelerated by the fan assembly and the motor in the duct assembly 260, flows through the wind tube 270, and then flows out from the air outlet 112. One end of the housing 100 is connected to the air inlet cover 113, and the other end is detachably connected to the wind tube 270. In one embodiment, the lighting device 600 is arranged above the axis 101 of the hair dryer, and the lighting device 600 is arranged behind the wind tube 270. In one embodiment, the lighting device 600 is arranged above the axis 101 of the hair dryer, and the height of the lighting device 600 in the up and down direction is higher than the wind tube 270. In one embodiment, the lighting device 600 is arranged between the air inlet cover 113 and the wind tube 270.

[0154] In some embodiments, such as Fig.17 and Fig.18 As shown, the hair dryer 10 is a backpack hair dryer, and the hair dryer 10 also includes a backpack device 920, which is used for the user to carry it, and the housing 100 is connected to the backpack device 920. In this embodiment, the hair dryer 10 also includes an operating handle 910, which is used for the user to hold, and the operating handle 910 is at least provided with a trigger and other components for controlling the action of the motor. The operating handle 910 is connected to the wind tube 270 or the housing 100. In one embodiment, the operating handle 910 is installed on the wind tube 270. In this embodiment, the light-emitting portion 614 is provided on the operating handle 910. Specifically, the housing of the operating handle 910 has a front side wall, and the light-emitting portion 614 is installed at the front side wall, so when the blower is in use, the light-emitting portion 614 can illuminate the blowing area on the front side and below the hair dryer 10.

[0155] In some embodiments, the lighting device 600 is detachably mounted relative to the hair dryer 10, so that the lighting device 600 can be easily replaced when it fails or is damaged.

[0156] like Figure 1As shown, the hair dryer 10 is a handheld hair dryer 10, and the handheld hair dryer 10 also includes a display 710, and the display 710 includes an electronic display screen. In one embodiment, the display 710 can display at least one of the power of the battery pack 130, the output speed of the handheld hair dryer 10, the operating position of the handheld hair dryer 10, the fault prompt, and the Bluetooth connection status. This facilitates the user to more intuitively and quickly obtain the current operating status of the hair dryer 10, and then more conveniently adjust the next operating parameters of the handheld hair dryer 10, thereby improving the user's experience. In some embodiments, the display 710 can display the operating position of the handheld hair dryer 10, the power of the battery pack 130, and the fault prompt. In some embodiments, the display 710 can display the output speed of the handheld hair dryer 10, the power of the battery pack 130, and the fault prompt. It can be understood that in other embodiments, the specific display content of the display 710 can be any one or a combination of several of the above parameters, which is not specifically limited here.

[0157] In some embodiments, Figure 1 As shown, the display 710 is arranged at the front side of the grip 150, so as to avoid blocking the display 710 when the user holds the hair dryer 10, and ensure the convenience of the user to view the display 710. It should be noted that the display 710 is arranged at the front side of the grip 150, which means that the display 710 is arranged at the front side of the position of the user's hand when the user holds the grip 150. Whether the user holds the hand forward or backward, the display 710 will not be blocked.

[0158] The display 710 is disposed on the casing 100 so that the casing 100 supports the display 710. In one embodiment, the display 710 may be flush with the outer surface of the casing 100, or may protrude from the outer surface of the casing 100, which is not specifically limited herein. In the present embodiment, the display 710 is disposed on the casing 100 and is disposed upward, thereby further improving the convenience of user viewing. Of course, in other embodiments, the display 710 may also be disposed to face the left, right, front or rear of the hair dryer 10. In some embodiments, the display 710 is disposed between the gripping portion 150 and the handle 400, thereby making the structure of the hair dryer 10 compact, and the display 710 being located between the two hands of the user will not hinder the user from viewing the display 710.

[0159] like Figure 2As shown, in one embodiment, the minimum distance between the display 710 and the control assembly 720 is less than or equal to 100 mm. In one embodiment, the minimum distance between the display 710 and the control assembly 720 is less than or equal to 50 mm. In this way, the length of the signal line between the display 710 and the control assembly 720 can be prevented from being too long, and the signal line can be prevented from being entangled due to being too long. The control assembly 720 is arranged in the space formed by the left housing 110 and the right housing 120. The left housing 110 and the right housing 120 are buckled together to form a hole, and the display 710 is arranged at the hole.

[0160] like Fig.19 and Fig. 20 As shown, the display 710 includes a screen box soft glue 711, a light-transmitting screen 712, a screen box hard glue 713, a light source 714, a communication board 715 and a control board 716. The screen box soft glue 711 and the screen box hard glue 713 are mutually buckled, and can support the light-transmitting screen 712, the light source 714, the communication board 715 and the control board 716, so that the display 710 is integrated into a whole, which is convenient for the installation of the display 710. In this embodiment, the electronic display screen is at least composed of a light source 714 and a control board 716. An Internet of Things communication module is arranged on the communication board 715. In one embodiment, a Bluetooth module, a wifi module, etc. are arranged on the communication board 715. The control board 716 is a PCB board, and the control board 716 is electrically connected to the control component 720 of the hair dryer 10. The light source 714 may be an LCD screen or an LED screen, and the light-transmitting screen 712 is disposed in front of the light source 714 . The light-transmitting screen 712 can allow light from the light source 714 to pass through and can protect the light source 714 .

[0161] The effective area S of the display 710 is defined as the displayable area of ​​the electronic display screen, and the effective area S is greater than or equal to 4 cm 2 In one embodiment, the effective area S is greater than or equal to 9 cm 2 and less than or equal to 15cm 2 In some embodiments, the effective area S is about 8 cm 2 , 10cm 2 、12cm 2 or 14cm 2 .

[0162] It is understandable that the above-mentioned technologies related to the display 710 can all be used in the backpack hair dryer 10, and no specific limitation is made here.

[0163] As can be seen from the foregoing, the lighting device 600 has at least one light-emitting portion 614, which in turn has at least one light-emitting element 615. Different light-emitting portions 614 can be disposed at any two positions of the hair dryer, and the two light-emitting portions 614 can be at least 5 cm apart, for example, one light-emitting portion 614 is disposed on the hair dryer 270, and the other light-emitting portion 614 is disposed near the grip portion 150. Each light-emitting portion 614 can include multiple light-emitting elements 615, for example, a light strip is composed of multiple lamp beads.

[0164] Fig.21 and Fig. 22 The light emitting member 615 is further described. Fig.21 for Figure 5 and Figure 7 A schematic diagram of any one of the light emitting elements 615, Fig. 22 615a and 615b, the light emitting member 615 is defined to extend along the first straight line 102, that is, the light emitted by the light emitting member 615 is distributed rotationally symmetrically around the first straight line 102. Specifically, the light emitting member 615 is a cubic lamp bead, and the light emitting member 615b is a cylindrical lamp bead.

[0165] In one embodiment, the angle between the first straight line 102 and the hair dryer axis 101 is greater than or equal to 10 degrees and less than or equal to 60 degrees. This arrangement helps to reduce the shadow formed on the ground when the hair dryer 270 blocks light.

[0166] It should be noted that the technical solutions described in this application may be applied to different airflow devices such as a handheld hair dryer, a backpack hair dryer, or a blower-suction machine with a blowing mode. When this application mentions "airflow equipment", it does not limit the type of airflow equipment. As long as the equipment works through the flow of airflow, it can be called "airflow equipment". The "hair dryer" involved in this application is not limited to a handheld hair dryer, a backpack hair dryer, or a blowing mode of a blower-suction machine. Therefore, when "hair dryer" is mentioned, it should be understood as a general term for various types of hair dryers, unless the text specifically defines a specific type of hair dryer.

[0167] When it comes to the specific difference between a "handheld hair dryer" and a "backpack hair dryer", we define it from the following perspectives: From one perspective, the battery pack 130 of the handheld hair dryer is connected to the housing 110, or in other words, the battery pack joint for mounting the battery pack 130 extends from the housing 110. Figure 1 and Figure 2As shown, the left housing 110 and the right housing 120 together form a battery pack joint for mounting the battery pack 130. The battery pack 130 of the backpack hair dryer is separated from the housing 110, and the battery pack joint is separated from the housing 110. When in use, the battery pack 130 is carried on the back of the user.

[0168] Figure 23 to Figure 33 Another embodiment of the present application is introduced. As a commonly used gardening tool, a blower uses a fan set inside to generate airflow to help users clean fallen leaves in the garden. For ease of carrying, backpack blower systems are currently mostly used, but backpack blower systems in related technologies are mostly supported by shoulder straps. When users carry the blower system on their shoulders, their shoulders will continue to bear a large amount of system weight, and they are still easily fatigued, resulting in a poor human-machine experience.

[0169] Fig.23 The backpack fan system 1000 as an embodiment of the present application is shown. The backpack fan system 1000 includes: a fan, a motor, and a battery pack 130. The fan is used to generate the airflow required for the system to work. The motor is connected to the fan, and the fan is driven by the motor shaft to rotate around the axis, thereby generating the above-mentioned working airflow. The battery pack 130 is connected to the motor and is used to at least power the motor.

[0170] The backpack fan system 1000 also includes an air duct device 20. The air duct device 20 contains a fan and is provided with an air duct for guiding the airflow generated by the fan. After the external air enters from the air duct inlet, the airflow channel is formed in the air duct by the rotation of the fan, and then is guided to the outside from the air duct outlet.

[0171] The backpack blower system 1000 also includes a carrying device 920 for a user to wear to carry the blower system. Fig.24 As shown, the backpack device 920 may include a device body 31, a shoulder strap assembly 32 and a waist belt assembly 33. The device body 31 is used to support the battery pack 130 and the air duct device 20. In some examples, the battery pack 130 includes a power supply connection portion that can be detachably connected to the rear side of the device body 31. In some examples, the air duct device 20 includes an air duct connection portion at the air duct entrance that can be detachably connected to the left and right sides of the device body 31. The shoulder strap assembly 32 is used for the user to wear on the shoulders, and the waist belt assembly 33 is used for the user to wear on the torso such as the waist, and the shoulder strap assembly 32 and the waist belt assembly 33 are both connected to the device body 31. In some embodiments, the battery pack 130 includes a battery pack, which is detachably mounted to the device body 31.

[0172] refer to Fig.25, the shoulder strap assembly 32 includes a shoulder strap connection portion 321 connected to the device body 31. The top 311 of the device body 31 is higher than the shoulder strap connection portion 321, that is, the highest point 311 of the device body 31 in the up-down direction exceeds the shoulder strap connection portion 321 in the up-down direction. In the case of a waist belt assembly 33, since the waist belt assembly 33 is connected to the lower side of the device body 31 and is clamped on the user's waist after being worn, and the top 311 of the device body 31 is higher than the shoulder strap connection portion 321, the battery pack 130 and the air duct device 20 are actually supported by the user's waist through the waist belt assembly 33, and the shoulder strap assembly 32 will basically not bear the force in the direction of gravity, but is used to keep the system from tipping over in the front-to-back direction.

[0173] Figure 23 to Figure 25 In the described embodiment, by adjusting the height relationship between the top of the backpack body and the shoulder strap connection part when a waist belt is provided, the force transmission in the backpack is changed, so that the weight of the system is transmitted to the waist of the human body with stronger pressure-bearing capacity, thereby effectively improving the carrying experience of the fan system and enhancing the comfort of the user when using the fan system.

[0174] The following is a more detailed description of the device body 31 in the backpack device 920 in the backpack blower system 1000 described above.

[0175] refer to Figure 26 to Figure 27 In some embodiments, the device body 31 includes a back plate 312 and a bracket 313. The bracket 313 is connected to the back plate 312 and supports the back plate 312. For example, the bracket 313 can be embedded in the back plate 312 or close to the surface of the back plate 312 to achieve the function of supporting the back plate 312. The top 311 of the device body 31 can be the top of the bracket 313, that is, the highest point of the bracket 313 in the up and down direction.

[0176] In some embodiments, the back plate 312 may be made of a first material, and the bracket 313 may be made of a second material different from the first material. The hardness of the second material may be greater than the hardness of the first material. For example, the back plate 312 may be made of hard plastic, and the bracket 313 may be made of stainless steel, so as to better achieve force conduction in the backpack.

[0177] In some embodiments, the bracket 313 is a high-strength bracket, and the hardness of the second material making the bracket 313 can exceed the hardness of conventional materials, for example, greater than or equal to 150 HR.

[0178] In some embodiments, the back plate 312 and the bracket 313 include curved surfaces that fit the curve of the human back in structure. Compared with conventional straight back plates and brackets, the force transmission between the human back and the back plate and bracket is more balanced, thereby improving the comfort of the user when carrying the fan system.

[0179] In addition, in some embodiments, the height H2 of the device body 31 exceeds the normal distance from the shoulder to the waist of the human body, for example, H2 is greater than or equal to 55 cm, so as to further ensure that the shoulder strap assembly does not bear the system force.

[0180] The following is a more detailed description of the shoulder strap assembly 32 in the backpack device 920 in the backpack blower system 1000 described above.

[0181] refer to Figure 28 to Figure 29 In some embodiments, the shoulder strap assembly 32 includes a shoulder strap connection portion 321 and a shoulder strap body 322. In one embodiment, the shoulder strap connection portion 321 detachably connects the shoulder strap body 322 to the device body 31 and is capable of adjusting the use length of the shoulder strap body 322. Although the shoulder strap body 322 is detachably connected to the device body 31 and the use length of the shoulder strap body 322 is variable, the connection position of the shoulder strap connection portion 321 on the device body 31 remains unchanged and is always lower than the top 311 in the vertical direction. For example, the shoulder strap connection portion 321 can be a Velcro provided on the surface of the shoulder strap body 322, and the shoulder strap can be detachably connected to the adhesive area 3121 provided on the inner upper part of the back plate 312 through the Velcro. Although the use length of the shoulder strap can be adjusted by changing the Velcro adhesion area, the highest point of the adhesive area 3121 in the vertical direction still does not exceed the top of the bracket, so that while improving the carrying experience, the shoulder strap connection portion also takes into account the shoulder strap removal and length adjustment functions. In addition, the shoulder strap connection portion 321 may also be provided with an auxiliary shoulder strap connection piece 324, which connects the shoulder strap body 322 and the device body 31, and while keeping the shoulder strap connection portion 321 lower than the top 311 of the device body 31, it assists in the connection between the shoulder strap body 322 and the device body 31. In another embodiment, the shoulder strap body 322 may be directly fixedly connected to the device body 31, for example, the shoulder strap body 322 and the device body 31 are fixed by sewing or the like.

[0182] In some embodiments, the shoulder strap assembly 32 includes a shoulder strap connection portion 321 and a shoulder strap body 322, and also includes a shoulder strap adjustment member 323. The shoulder strap adjustment member 323 detachably connects the shoulder strap body 322 to the waist belt assembly 33 and can adjust the use length of the shoulder strap body 322 in the up-down direction. For example, the shoulder strap adjustment member 323 can be a buckle with a portion of the shoulder strap body 322 inserted at one end and the other end connected to the waist belt assembly 33. The user can adjust the use length of the shoulder strap in the up-down direction by pulling the shoulder strap inserted in the buckle, so as to ensure the comfort of users of different body shapes when using the fan system.

[0183] Furthermore, in some embodiments, the shoulder strap assembly 32 may include a shoulder pad in addition to the shoulder strap connection portion 321 and the shoulder strap body 322 to further reduce the shoulder burden of the user.

[0184] The waist belt assembly 33 in the backpack device 920 in the backpack blower system 1000 described above is described in more detail below.

[0185] refer to Figure 30 to Figure 33 In some embodiments, the waistband assembly 33 includes a waistband body 331. The waistband body 331 is used to fit the user's torso. In order to enable the waistband body 331 to completely wrap the user's waist in a tightened state, the contact area between the waistband body 331 and the user's torso can be increased. Fig.31 As shown, the maximum width L3 of the waistband body 331 in the vertical direction can exceed the conventional waistband width, for example, L3 is greater than or equal to 10 cm, so that the force from the device body 31 is more evenly distributed to the user's waist through the waistband body 331. Fig.32 As shown, the maximum thickness L4 of the waist belt body 331 may also exceed the conventional waist belt thickness, for example, L4 is greater than or equal to 0.8 cm, to prevent a waist belt that is too thin from being unable to bear the weight of the system. It is understandable that adjusting the maximum width and maximum thickness of the waist belt body 331 is only one way to increase the contact area between the waist belt body 331 and the user's torso. In some examples, the average width and average thickness of the waist belt body 331 may also be increased.

[0186] In some embodiments, the waistband body 331 may be made of a third material, and the surface friction coefficient of the third material may exceed the surface friction coefficient of conventional materials, so that the force exerted by the user's waist to the support system can be effectively transmitted.

[0187] In some embodiments, the waist belt assembly 33 includes a waist belt adjusting member 332 in addition to the waist belt body 331. The waist belt adjusting member 332 is used to adjust the use length of the waist belt body 331 in the ring direction around the user's waist so that the waist belt body 331 can be wrapped around the user's waist, so that the waist belt body 331 can be tightened, and the force from the device body 31 can be effectively transmitted to the user's waist.

[0188] In some embodiments, the waist belt assembly 33 further includes a waist pad 333. The waist pad 333 is filled with a filler such as sponge and has a certain thickness, and is arranged between the device body 31 and the user's back waist. For example, it can be arranged between the lower side of the back plate and the user's back waist to fill the gap between the device body 31 and the user's back waist and fit the user's back waist, so that the force from the device body 31 is effectively transmitted to the user's back waist.

[0189] In some embodiments, the waist belt assembly 33 includes a waist pad adjusting member 334 in addition to the waist pad 333. The waist pad adjusting member 334 detachably connects the waist pad 333 to the device body 31 and can adjust the position of the waist pad 333 on the device body 31. For example, the waist pad adjusting member 334 can be a Velcro provided on the surface of the waist pad 333, and the waist pad can be detachably connected to any position in the Velcro attachable area provided on the lower inner side of the back plate through the Velcro, so that the waist pad can function when users of different body shapes use the fan system, meeting the needs of different groups of people and improving the user's carrying experience.
