[0032] When in use, the hair dryer body 1 serves as the main structure of the garden backpack hair dryer. A gripping handle can be installed on the second air duct 14 to control the blowing direction. The engine 11 is installed inside the hair dryer body 1 to drive the fan blades to blow air. The power of the engine 11 is set to three gears, namely, the first gear, the second gear and the third gear. The power of the first gear is less than the power of the second gear, and the power of the second gear is less than the power of the third gear. When blowing air on debris in a separate area, the engine 11 starts working in the first gear to drive the fan blades to blow air into the inside of the first air duct 12, and the wind enters the inside of the second air duct 14 along the first corrugated pipe 13. The wind is introduced into the upper layer of the connecting pipe 15 by relying on the switching mechanism to flow to the DC air duct 16 for blowing out, so that the DC blowing through the DC air duct 16 can be used to remove debris in a separate area. When blowing air to debris in a large area, the DC air duct 16 and the shunt air duct 17 are blown out at the same time, and the wide-angle blowing through the DC air duct 16 and the shunt air duct 17 can be used to remove debris in a large area; when blowing air to the debris in a wide area, the engine 11 starts the third gear to drive the fan blades to blow air, and the wind is introduced into the lower layer of the connecting pipe 15 by relying on the switching mechanism to flow to the shunt air duct 17 and blown out, which can be used to remove debris in a wide area through the wide-angle blowing through the shunt air duct 17, which plays a role in freely and quickly switching different blowing heads according to different environments and needs, thereby improving the applicability of the garden backpack hair dryer; when the wind generated by the engine 11 enters the second air duct 14 to switch the flow direction, the first shunt slot on the shunt cylinder 2 The first and second shunt grooves 19 and 20 lead to the upper channel and the lower channel formed by the connecting pipe 15 and the baffle plate 18, respectively. When the power of the engine 11 is in the first gear, the flow control component opens the first shunt groove 19 and closes the second shunt groove 20, and the wind flows to the upper channel and is blown out from the DC air duct 16; when the power of the engine 11 is in the second gear, the flow control component opens the first shunt groove 19 and the second shunt groove 20 at the same time, and the wind flows to the upper channel and the lower channel from the DC air duct 16 and the shunt air duct 17 at the same time; when the power of the engine 11 is in the third gear, the flow control component closes the first shunt groove 19 and opens the second shunt groove 20, and the wind flows to the lower channel from the shunt air duct 17, which plays a role in controlling the flow direction of the wind; when the first wind When the air entering the tube 12 flows through the first corrugated tube 13 to the second air duct 14, the wind first enters the interior of the sliding cylinder 3. When the power of the engine 11 is in the first gear, the first air port 21 on the sliding cylinder 3 is connected to the upper channel through the first diverter groove 19, and the second diverter groove 20 is in a state of being blocked and closed by the sliding cylinder 3, and the wind flows to the upper channel and is blown out from the DC air duct 16; when the power of the engine 11 is in the second gear, the first air port 21 on the sliding cylinder 3 is connected to the upper channel through the first diverter groove 19, and the second air port 22 is connected to the lower channel through the second diverter groove 20.

[0033] Example 2

[0034] like Figure 1 to Figure 3 , Figure 5 As shown, what is different from Example 1 is that the first air duct 12 described in this embodiment is fixedly connected with a first ring frame 4, the bottom end of the first ring frame 4 is fixedly connected with a fixed disk 24, the bottom end of the fixed disk 24 is rotatably connected with a rotating disk 25, a limiting assembly is provided on the fixed disk 24, and a supporting mechanism is provided on the rotating disk 25, and the supporting mechanism is used to support and connect the rotating disk 25 and the second air duct 14; the limiting assembly includes a fixed frame 5, a first limiting rod 26 and a second elastic member 27, a plurality of fixed frames 5 are fixedly connected to the top of the fixed disk 24, and a plurality of corresponding limiting holes are provided on the fixed disk 24 and the rotating disk 25, the first limiting rod 26 is slidably connected to the inner wall of the fixed frame 5, the end of the first limiting rod 26 close to the rotating disk 25 is set as an arc, and the end of the first limiting rod 26 away from the fixed frame 5 can penetrate the fixed disk 24 and be inserted into the limiting hole of the rotating disk 25 The second elastic member 27 is fixedly connected between the inner wall of the fixing frame 5 and the first limiting rod 26; the supporting mechanism comprises a wheel disc 6, a second ring frame 28 and a plug-in assembly, the wheel disc 6 is rotatably connected to the protrusion of the rotating disk 25, the second ring frame 28 is fixedly connected to the wheel disc 6, and the end of the second ring frame 28 away from the wheel disc 6 is sleeved on the second air duct 14, the plug-in assembly is arranged on the protrusion of the rotating disk 25, and the plug-in assembly is used to limit the rotation angle of the wheel disc 6; a plurality of plug-in holes are provided on the wheel disc 6, the plug-in assembly comprises a second limiting rod 7 and a third elastic member 29, the second limiting rod 7 is slidably connected to the protrusion of the rotating disk 25, and the second limiting rod 7 can pass through the plug-in hole of the rotating disk 25 to plug the wheel disc 6, the third elastic member 29 is sleeved on the second limiting rod 7, and the third elastic member 29 is located between the outer wall of the rotating disk 25 and the second limiting rod 7.

[0035] Working process or working principle:

[0036] When in use, since long-term single-handed operation to control the blowing direction may easily lead to physical fatigue, the first ring frame 4 is used to fix the fixed plate 24 on the first air duct 12, and the supporting mechanism connected with the rotating plate 25 is fixed on the second air duct 14. The rotating plate 25 is rotated left and right and the flexibility of the first corrugated tube 13 can be used to adjust the blowing direction of the front end of the second air duct 14, and the rotating plate 25 is limited by the limiting component, and the blowing direction is fixed synchronously, which replaces the method of controlling the blowing direction with one hand for a long time, reducing The invention can reduce the fatigue caused by long-term use of the garden backpack hair dryer; when the rotating disk 25 is rotated left and right to adjust the blowing direction, the plurality of first limiting rods 26 penetrate the limiting holes of the fixed disk 24 under the elastic support of the plurality of second elastic members 27, and the arc ends of the plurality of first limiting rods 26 are inserted into the limiting holes of the rotating disk 25. As the rotating disk 25 is adjusted and rotated, the limiting holes of the rotating disk 25 squeeze the arc ends of the plurality of first limiting rods 26, and the plurality of first limiting rods 26 are squeezed by the rotating disk 25 and slide up inside the plurality of fixing frames 5. The plurality of first limiting rods 26 are respectively pressed into the limiting holes of the rotating disk 25 until the plurality of first limiting rods 26 correspond to the other limiting holes on the rotating disk 25 again, so as to limit the rotation direction of the rotating disk 25; when the blowing direction of the front end of the second air duct 14 is adjusted up and down, the wheel plate 6 is used to adjust and rotate on the protruding part of the rotating disk 25, and the wheel plate 6 synchronously drives the second air duct 14 sleeved by the second ring frame 28 to adjust the blowing direction. After the blowing direction is adjusted, the second air duct 14 sleeved by the second ring frame 28 is used to adjust the blowing direction. The plug-in assembly limits the rotation angle of the wheel disc 6, thereby completing the up and down adjustment of the blowing direction; when the wheel disc 6 is rotated up and down to adjust the blowing direction, first pull the second limit rod 7 that has been inserted into the plug-in hole of the wheel disc 6, and the third elastic member 29 is stretched and stressed. After adjusting the rotation angle of the wheel disc 6, release the second limit rod 7, and the elastic force of the third elastic member 29 resets and drives the second limit rod 7 to pass through the protruding part of the rotating disk 25, and is plugged in other plug-in holes of the wheel disc 6 to limit the position, thereby limiting the up and down rotation angle of the wheel disc 6.

[0037] Example 3

[0038] like Figures 1 to 3 , Figure 6 As shown, different from other embodiments, the first air duct 12 described in this embodiment is provided with a solenoid valve 8, the solenoid valve 8 is connected to the engine 11, the outer wall of the solenoid valve 8 is fixedly connected with a guide tube 30, and the end of the guide tube 30 away from the solenoid valve 8 is connected to the engine 11; the top of the solenoid valve 8 is provided with a guide frame 9, the end of the guide frame 9 away from the solenoid valve 8 is fixedly connected with a second bellows 10, and the end of the second bellows 10 away from the guide frame 9 is fixedly connected with a guide head 31; the guide frame 9 is installed with a connecting valve 32, and the guide frame 9 is located on the guide frame 9 near the solenoid valve 8.

[0039] Working process or working principle:

[0040] When the engine 11 is working and drives the fan blades to blow air, since the engine 11 is turned on at the third gear power and works for a long time, it is easy to run at high temperature and reduce the use time. The solenoid valve 8 is connected to the first air duct 12, and the solenoid valve 8 is connected to the engine 11 inside the hair dryer body 1 through the guide tube 30. When the engine 11 is turned on at the third gear power and works, it can synchronously send an electrical signal to the main controller. The main controller controls the solenoid valve 8 to open, and part of the wind sent into the first air duct 12 enters the solenoid valve 8 and the guide tube 30 and flows back to the engine 11, so as to dissipate heat on the engine 11 and reduce the harm caused by the long-term high-temperature operation of the engine 11. At the same time, when the temperature of the engine 11 exceeds the set value, the solenoid valve 8 will be opened to dissipate heat at the engine 11. When the weather is hot, when the staff use the garden backpack hair dryer for a long time, due to the dual influence of weather and long-term work, the staff It is easy to get hot and sweat severely, which affects the continuous development of work. The guide frame 9 is connected with the solenoid valve 8, and the second bellows 10 is adjusted to a suitable blowing angle in conjunction with the guide head 31. The blowing direction of the guide head 31 is aimed at the part of the body that needs air blowing to cool down. After the solenoid valve 8 is opened when air enters the first air duct 12, part of the wind enters the guide frame 9 and the second bellows 10 to reach the guide head 31 for blowing, which can dissipate heat to local areas of the body and increase the duration of the operation; when the guide tube 30 is used to dissipate heat to the engine 11, if it is not necessary to dissipate heat to local areas of the body through the guide head 31, the connecting valve 32 can be rotated to control the connectivity of the internal channel of the guide frame 9 to block the internal channel of the guide frame 9. When the guide head 31 is needed, the connecting valve 32 is rotated in the opposite direction to open the internal channel of the guide frame 9, thereby achieving the function of controlling the connectivity of the internal channel of the guide frame 9.

[0041] The garden backpack hair dryer of the present invention achieves technical effects such as multi-angle adjustment of the blowing direction, reducing operating fatigue during long-term use, and extending the service life of the engine by setting a switching mechanism, a supporting mechanism, and a heat dissipation system in the garden backpack hair dryer. On one hand, the switching mechanism can guide the wind to blow in various directions by controlling the flow direction of the wind to meet the wind output of different regions and different needs. A rotatable and adjustable supporting mechanism is set so that the user can easily control the blowing direction and reduce the fatigue caused by long-term one-handed operation. In addition, a heat dissipation system is designed to effectively reduce the damage to the engine caused by long-term high-temperature operation by guiding part of the wind back to the engine for cooling, extending the service life, and can dissipate heat from the body when the weather is hot or when working hard, thereby increasing the duration of the operation.
