Detailed implementation manners

[0032] Now, further detailed description of the present utility model will be made in conjunction with the attached drawings.

[0033] Please refer to Figures 1 to 8The utility model provides a technical solution: a portable turbofan, comprising a portable turbofan body 1, a housing of the portable turbofan body 1 having a groove for mounting a base 2, an L-shaped seat 3 fixed to the top of the inner portion of the groove, a first rotating member 4 hingedly connected to one side of the lower end of the L-shaped seat 3, first positioning blocks 5 fixed to the outer edges of both front and rear ends of the first rotating member 4, a first magnet 7 for adsorbing a first metal block 6 fixed inside the first positioning block 5, and the first metal blocks 6 distributed in a ring array on both sides of the lower end of the L-shaped seat 3;

[0034] A pillar 8 is provided below the first rotating member 4, and a cavity for the stretching rod 9 to pass through is opened inside the side ends of the pillar 8 and the first rotating member 4, and the two stretching rods 9 are fixed by a stop bolt 10. The two stop bolts 10 are respectively threadedly connected to the side of the first rotating member 4 and the pillar 8, and the ends of the two stretching rods 9 are respectively sleeved with the second rotating member 11 and the third rotating member 12. The second rotating member 11 and the third rotating member 12 are fixed to the stretching rod 9 by fixing bolts 13. The ends of the second rotating member 11 are hinged to the third rotating member 12 through a column 14. Second positioning blocks 15 are fixed to the outer edges of the front and rear ends of the main body, and a second magnet 17 for adsorbing the second metal block 16 is fixed inside the second positioning block 15. The second metal blocks 16 are distributed in a ring array on the front and rear sides of the third rotating member 12. A cross plug block 19 is fixed to the side end of the pillar 8, which is plugged into the plug block 18. The plug block 18 is fixed to the base 2, and the bottom of the base 2 is fixedly bonded with an anti-slip pad 20;

[0035] An air outlet cavity 21 is provided on the front side of the portable turbofan body 1, and a plurality of fan blades 22 are provided inside the air outlet cavity 21. A control panel 23 is installed on the side of the portable turbofan body 1, and a switch button 24 is provided in the middle of the control panel 23. Considering that the existing portable turbofan cannot adjust the use height and use angle of the device according to the needs of the user, and cannot change the air supply angle, which is not conducive to the use of the user, the present invention is convenient for users to use. The metal block 16 adjusts the use angle of the device, that is, it can adjust the inclination and elevation of the air supply. The inclination and elevation of the air supply can be adjusted by rotating the first rotating member 4 and the L-shaped seat 3. Secondly, the second rotating member 11 can be rotated to adjust the rotation angle of the second rotating member 11 and the third rotating member 12, thereby performing a third inclination and elevation adjustment. When the use height of the device needs to be adjusted, the limit bolt 10 used to fix the two stretching rods 9 will be loosened to stretch the use length of the first rotating member 4 and the stretching rod 9, and the use length of the third rotating member 12 and the support 8 will be stretched. After stretching, the limit bolt 10 will be tightened to complete the length locking.

[0036] Among them, a shaft body 25 is connected through the middle of each air supply fan blade 22. The lower end of the shaft body 25 is rotatably connected to the bottom of the air outlet cavity 21 through a bearing. The upper end of the shaft body 25 penetrates to the outside of the housing of the portable turbo fan main body 1 and is fixed to the driven gear ring 26. One side of each driven gear ring 26 is engaged with the teeth 28 of the rack 27. This device can utilize the multiple driven gear rings 26 to be pulled by the rack 27, so that the teeth 28 drive the driven gear ring 26 to rotate, so as to make the multiple air supply fan blades 22 rotate. When the multiple air supply fan blades 22 rotate, the air supply angle is changed to complete the adjustment.

[0037] Among them, a guiding groove 30 adapted to the outer contour of the T-shaped track 29 is formed on the side of the rack 27. The T-shaped track 29 is fixedly installed on the side of the support plate 31, and the support plate 31 is fixedly installed on the upper end of the housing of the portable turbo fan main body 1. By arranging the T-shaped track 29 to cooperate with the support plate 31, a guiding effect on the rack 27 is achieved, that is, when the rack 27 is pulled, the rack 27 will be guided through the guiding groove 30 on the back in cooperation with the T-shaped track 29, avoiding the situation that the position of the rack 27 shifts during the pulling process, thus causing the dislocation of the teeth 28 and the driven gear teeth.

[0038] Among them, L-shaped bars 32 are symmetrically and fixedly installed on the upper end of the housing of the portable turbo fan main body 1. A dust-proof strip 33 is clamped between the two L-shaped bars 32, and the dust-proof strip 33 covers the outside of the multiple driven gear rings 26. At the same time, the L-shaped bars 32 and the dust-proof strip 33 are connected by clamping, which facilitates the user to quickly disassemble the dust-proof strip 33 to maintain the driven gear rings 26 and the rack 27.

[0039] Among them, U-shaped bars 34 are fixedly installed at both the upper and lower ends of the portable turbo fan main body 1. An installation plate 35 is clamped between the two U-shaped bars at each end, and a groove for installing a dust-proof net 36 is formed in the middle of the installation plate 35. By arranging the dust-proof net 36, it plays a role in filtering the air inhaled during the operation of the turbo fan, preventing dust from being inhaled and adhering to the surface of the fan blades of the turbo fan, thus affecting the operation of the turbo fan blades.

[0040] Among them, guide columns 38 adapted to the middle strip groove of the tension rod 9 are fixedly installed inside the first rotating member 4 and the support column 8, and the guide columns 38 are fixedly installed inside the support column 8 and the first rotating member 4. At the same time, the arrangement of the guide columns 38 ensures that the tension rod 9 can be horizontally pulled out from the inside of the first rotating member 4 and the support column 8 without any position deviation.

[0041] Among them, a polyurethane sheath 39 is sleeved outside the housing of the portable turbo fan body 1.让位 holes for the rack 27, U-shaped strip 34, dust-proof strip 33 and base 2 to move are provided outside the polyurethane sheath 39. By setting the polyurethane protective sheath, the housing of the portable turbo fan body 1 is protected. When the device falls, the housing of the device will be protected by the polyurethane protective sheath.

[0042] Among them, a hanging ring 40 is integrally formed at the upper end of the polyurethane sheath 39, and a portable rope sleeve 37 is fixed inside the hanging ring 40. By setting the portable rope, it is convenient for the user to carry this device.

[0043] The utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the utility model, as long as they have the same or similar technical solutions as the utility model, all fall within the protection scope of the utility model. The technologies, shapes and structures not described in detail in the utility model are all well-known technologies.
