For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Example, see Figures 1 to 12A backpack-type hair dryer that is easy to hold in hand comprises a backpack seat 1 equipped with a strap, the backpack seat 1 is connected to a remote control bearing plate 2 through a rocking control component, further, the rocking control component comprises a bearing seat 44 connected to the remote control bearing plate 2 through a bearing shaft 43, a damping shaft 30 is arranged on the side wall of the bearing seat 44, a storage frame 31 is arranged on the backpack seat 1, and a damping connection port matched with the damping shaft 30 is opened on the storage frame 31, wherein the setting of the damping shaft 30 can realize the horizontal rotation of the bearing seat 44 to achieve the effect of multi-angle support, wherein in order to ensure the connection between the bearing seat 44 and the backpack seat 1, a pull rod can be arranged on the back for stable force.

[0020] It should be noted that the bearing seat 44 connected to the bearing shaft 43 enables the remote control bearing plate 2 to rotate on the bearing seat 44. This allows the backpack hair dryer to be rotated at any angle below the vertical angle when working, thereby effectively avoiding the occurrence of bending and satisfying the use state of the handheld DC air duct 10 when in use.

[0021] Two groups of vertical bearing seats 3 are arranged on the remote control bearing plate 2, and the vertical bearing seats 3 are connected to the blower drive cover 5 through the limit clamping seat 4. The remote control bearing plate 2 is provided with a height adjustment component for controlling the height of the blower drive cover 5. Furthermore, the height adjustment component includes a control cavity opened on the remote control bearing plate 2, and a traction control strip 32 is arranged in the control cavity. One end of the traction control strip 32 is fixedly connected to a control shaft 33, and the control shaft 33 extends downward through the side wall of the remote control bearing plate 2 and is fixedly connected to a pulling handle. The inner side wall of the control cavity is connected to the traction control strip 32 through a sleeve resistance spring sleeved on the outer side wall of the control shaft 33. The setting of the sleeve resistance spring can achieve the effect of resetting the traction control strip 32.

[0022] Furthermore, a groove is provided on the inner side wall of the bearing vertical seat 3, and a one-way limit rack 34 is connected to the inner side wall of the groove through a resisting spring. A limit tooth groove matched with the one-way limit rack 34 is provided on the limit clamping seat 4, and a connecting protrusion is provided on the back of the one-way limit rack 34. The traction control strip 32 is connected to the traction cross block 35, and traction connecting rods 36 connected to the connecting protrusions on both sides are provided on both sides of the traction cross block 35.

[0023] The remote control bearing plate 2 is provided with a rectangular opening for horizontal movement of the traction cross block 35, and the side wall of the bearing vertical seat 3 is provided with a moving opening for the connection protrusion to move; When the height of the blower drive hood 5 needs to be adjusted downward, the pulling handle can be pulled to release the matching state between the one-way limit rack 34 and the limit tooth groove. When the blower drive hood 5 needs to be adjusted upward, the blower drive hood 5 can be pushed upward. The one-way limit rack 34 is a one-way tooth, which can achieve downward limitation but cannot achieve upward limitation, thereby meeting the adjustment requirements during use.

[0024] Centrifugal blast blades 6 are arranged in the blast drive cover 5, and the remote control bearing plate 2 is connected to the powerful blowing motor 7 through a support member, and the powerful blowing motor 7 is connected to the centrifugal blast blades 6 through an adjustable transmission assembly; further, the adjustable transmission assembly includes a multi-faceted rotating shaft 37 fixedly connected to the output end of the powerful blowing motor 7, a transmission dust cover 38 is fixedly connected to the side wall of the blast drive cover 5, a worm sleeve 39 is rotatably arranged on the inner wall of the transmission dust cover 38, and the worm sleeve 39 is slidably sleeved on the multi-faceted rotating shaft 37, and the centrifugal blast blades 6 are connected to a transmission worm gear 40 through a drive shaft that penetrates into the transmission dust cover 38.

[0025] It should be noted that the inner wall of the worm sleeve 39 is provided with a multi-edge opening for sliding connection with the multi-edge shaft 37. The structural setting can transmit the rotational force of the multi-edge shaft 37 to the worm sleeve 39, thereby achieving the effect of torque transmission.

[0026] An air outlet hood 8 is provided at the air outlet of the blower drive hood 5. It is necessary to ensure that the outlet of the air outlet hood 8 is in the tangent direction with the blower drive hood 5 to avoid eddy currents at the connection to hinder wind transmission. A DC air outlet pipe 9 is connected to one end of the air outlet hood 8. The DC air outlet pipe 9 is connected to a handheld DC air pipe 10 through a retractable elbow assembly. Furthermore, the retractable elbow assembly includes a DC storage cover 16 connected to the handheld DC air duct 10, a bent hose 17 is fixedly provided at the end of the DC air outlet pipe 9, and both ends of the bent hose 17 are fixedly provided with a limit stop ring 18, and the limit stop ring 18 away from one end of the DC air outlet pipe 9 is in the DC storage cover 16 and is fixedly connected to a negative pressure rubber ring 19; The DC receiving cover 16 is provided with a matching ring groove 20 adapted to the negative pressure rubber ring 19, and the inner side wall of the matching ring groove 20 is provided with a plurality of negative pressure suction holes 21 arranged obliquely; It should be noted that when the hair dryer is in use, the bent hose 17 is pushed inward so that the negative pressure rubber ring 19 provided at the end of the bent hose 17 is located in the matching ring groove 20. When the DC air outlet pipe 9 is discharging air, a strong suction force is generated on the negative pressure suction hole 21 under the action of the high-speed airflow, so that the negative pressure rubber ring 19 is firmly adsorbed, thereby avoiding the situation in which the bent hose 17 is stretched out and the pipe is bent, affecting the air outlet, during use.

[0027] A further advantage of the above method is that when the hair-drying operation is not being performed, the bending hose 17 stored in the DC storage cover 16 can be extended outward. By setting the bending hose 17, the relatively long handheld DC air duct 10 can be bent and stored, thereby facilitating the carrying and storage of the backpack-type hair dryer. The handheld DC air duct 10 is provided with an air duct switching control ring 11, and the air duct switching control ring 11 is connected with an inner control deformation member through an adjusting rotary ring 12, and a plurality of inner control deformation members are evenly provided. Further, the inner control deformation member includes an inner ring body 22 slidably arranged in the air duct switching control ring 11, and the inner ring body 22 plays the effect of supporting the adjusting column 23. A telescopic opening penetrating the side wall is provided on the inner ring body 22, and an adjusting column 23 is slidably arranged on the inner wall of the telescopic opening. The adjusting column 23 slides in the telescopic opening, and a plurality of linkage adjustment rods 24 are rotatably connected to the inner wall of the adjusting rotary ring 12, and the other end of the linkage adjustment rod 24 is rotatably connected to the side wall of the adjusting column 23, wherein a notch for the linkage adjustment rod 24 to move is provided on the inner ring body 22; A traction ball 25 is provided at the end of the adjustment column 23, and a limit sliding opening is provided on the traction ball 25 for the traction elastic rope 13 to slide, wherein the traction elastic rope 13 slides in the limit sliding opening and can ensure an effective connection between the two to realize the movement of the traction elastic rope 13.

[0028] A traction elastic rope 13 is provided at the end of the inner control deformation member. The elastic deformation of the traction elastic rope 13 has a certain limit, and its elastic force is much smaller than the elastic force of the strong connecting spring. Torsion connectors are provided at both ends of the traction elastic rope 13. One end of the torsion connector is connected to the inner wall of the handheld DC air duct 10, and the other end is connected to an adjusting wind dispersion ring 14. The outer wall of the handheld DC air duct 10 is threadedly connected with a threaded adjustment cover 41. The threaded adjustment cover 41 is connected to a plurality of extension columns 42 through a rotating ring. The setting of the rotating ring can ensure the threaded connection of the threaded adjustment cover 41. The other end of the extension column 42 is connected to the adjusting wind dispersion ring 14. A windproof elastic strip 15 is fixedly connected to the traction elastic rope 13. The plurality of windproof elastic strips 15 are in contact with each other to form an annular wind-blocking structure.

[0029] Furthermore, the torsion connector includes an installation end 26, in which an end connection groove is opened. The inner wall of the end connection groove is connected to a limit plate 27 through a strong connection spring. A rotating disk is provided at the end of the limit plate 27 to be rotatably connected to the strong connection spring. The end of the traction elastic rope 13 passes through the end connection groove and is fixedly connected to the limit plate 27. A plurality of guide inclined grooves 28 are opened on the inner side wall of the end connection groove, and a plurality of torsion protrusions 29 located in the guide inclined grooves 28 are provided on the side wall of the limit plate 27.

[0030] When the inner control deformation part moves inward, the position of the traction elastic rope 13 will be changed, and the windproof elastic strips 15 arranged on both sides of the traction elastic rope 13 can realize continuous change of the funnel-shaped angle, thereby achieving the effect of controlling the size of the air outlet and meeting the needs of the hair dryer outlet.

[0031] When the inner control deformation part moves inward to the gathered state, the traction elastic rope 13 will move under the action of the resistance force of the traction ball 25, so that the traction elastic rope 13 is in a taut state, and a pulling force is generated on the torsion connecting parts arranged at both ends. The limit plate 27 under the action of the pulling force will be driven to move in the end connecting groove. In the process of movement, the torsion protrusions 29 on both sides of the limit plate 27 are driven to rotate in the guide inclined groove 28. The rotation of the limit plate 27 will cause the traction elastic rope 13 to be driven to rotate 90°, thereby causing the windproof elastic strips 15 that were originally arranged in a gathered state to rotate, so that the annular wind-blocking structure composed of multiple windproof elastic strips 15 is opened, so that the wind overflows from the surroundings and is discharged outward by adjusting the wind dispersion ring 14, so as to achieve the wind dispersion from the center to the surroundings, meeting the cleaning needs.

[0032] When the backpack hair dryer is working, the backpack seat 1 supports the remote control bearing plate 2, and the handheld DC air duct 10 controls the direction of the air outlet. During the whole blowing process, the vertical rotation angle of the remote control bearing plate 2 is controlled by shaking the control member, and the height of the air blowing drive cover 5 arranged on the remote control bearing plate 2 is controlled by the control shaft 33, which can be adjusted according to the needs of the air outlet of the handheld DC air duct 10. During use, the handheld DC air duct 10 can control the remote control bearing plate 2 to rotate on the bearing seat 44 to achieve multi-angle adjustment, thereby ensuring that the entire pipeline from the air outlet cover 8 to the air outlet of the handheld DC air duct 10 will not bend, avoiding the weakening of wind force, ensuring the use of the hair dryer, and avoiding the generation of wind noise. During use, the mode of air outlet can be switched according to the required mode. When concentrated air outlet is required, it is only necessary to rotate the adjusting ring 12. The adjusting ring 12 will drive the linkage adjusting rod 24 to move, thereby squeezing the adjusting column 23, so that the traction ball 25 connected to the adjusting column 23 moves, and multiple traction balls 25 move inward, so that the windproof elastic strips 15 arranged on the traction balls 25 form a funnel shape, thereby guiding and gathering the wind force, and achieving the effect of concentrated output. When it is necessary to generate wind force from the center to the surroundings, the traction balls 25 connected to the adjusting column 23 can be moved inward and gradually gathered, synchronously The threaded adjustment cover 41 is controlled to rotate so that the adjustment wind dispersion ring 14 connected to it moves outward, generating tension on the mounting ends 26 set at both ends of the traction elastic rope 13, and the torsion protrusions 29 on both sides of the limit plate 27 are driven to rotate in the guide inclined groove 28. The rotation of the limit plate 27 will drive the traction elastic rope 13 to rotate 90°, thereby rotating the windproof elastic strips 15 that were originally gathered together, so that the annular wind-blocking structure composed of multiple windproof elastic strips 15 is opened, so that the wind overflows from all sides and is discharged outward through the adjustment wind dispersion ring 14, so as to realize the wind dispersion from the center to all sides, meeting the cleaning needs.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
