Above-mentioned structure, the motor drives the amount of wind that the flabellum rotated the production, because the locating plate shelters from the top, and can only pass through the filter core from the side, then gets into wind ring left side portion 10 and wind ring right side portion 11 respectively, wind ring left side portion 10 and wind ring right side portion 11 upper portions, then from the air outlet air-out. Because of the existence of the baffle, the air volume of the air ring left side part 10 and the air ring right side part 11 can not generate impact on the upper part, and the air volume is discharged from each air outlet when discharged, so that the air is completely discharged from the air outlet, and the air cooling effect is improved.
The locating groove 9 is arranged on the outer side of the left side part 10 of the wind ring, the locating groove 9 is arranged on the outer side of the right side part 11 of the wind ring, one locating block 8 is arranged on one side of the upper part of the base 1, and the other locating block 8 is arranged on the other side of the upper part of the base 1. Above-mentioned structure, every side sets up constant head tank and locating piece respectively, realizes base and wind ring location to realize the horizontal direction location, like this, when adjusting motor rotates the drive lead screw and rotates, the wind ring can only reciprocate for the base, thereby realizes altitude mixture control. And the closing plate 3 is used for arranging a screw hole block and is connected with a screw rod in a screwing way. The adjusting motor is installed above the positioning plate, and the positioning plate is fixed to realize fixed arrangement of the adjusting motor.
The inner wall of the base 1 is provided with an annular groove 15 which is arranged along the circumference of the inner wall of the base 1, a sealing ring 16 is clamped in the annular groove 15, and the sealing ring 16 protrudes out of the inner wall of the base 1. Above-mentioned structure, behind the seal ring setting, the sealing ring adopts rubber materials to make, and the sealing ring laminating is close to the lower part surface at the wind ring, reciprocates the in-process at the wind ring for the base, and is sealed all the time, avoids the amount of wind to reveal. In this way, the air volume passing through the filter element is ensured to be reliably introduced into the air ring left side portion 10 and the air ring right side portion 11 all the time. And the bottom of the base is provided with a base plate which can be connected with the base body. Therefore, the filter element is convenient to disassemble and clean or replace in the base. When the base plate is disassembled, the base plate and the base body are loosened firstly, then the adjusting motor rotates, the screw rod rotates relative to the screw hole block until the screw rod completely exits the screw hole, and the steps are opposite during installation.
A motor 17 is arranged in the base 1, fan blades 18 are arranged on the motor 17, and an annular filter element 19 is arranged on the periphery of each fan blade 18. The bolt passes through the base 1 and is connected with the lower part of the filter element 19, and the positioning plate 5 arranged on the base 1 close to the upper part is arranged on the upper part of the filter element 19 through the bolt. Above-mentioned structure, the motor is installed on the base plate, and the filter core is the annular structure, can install on the base plate through the bolt, ensures that the filter core position realizes fixedly, sets up sealed the pad between filter core and the base plate. A gasket 20 is interposed between the positioning plate 5 and the upper portion of the filter element 19. Above-mentioned structure through the setting of sealed pad for the amount of wind that the flabellum produced can only pass through from the filter core, then gets into the wind channel.
The air ring left side part 10 of the air ring 2 is provided with a plurality of air outlets 21 from top to bottom in a clearance way. The air ring right side part 11 of the air ring 2 is provided with a plurality of air outlets 21 from top to bottom in a clearance way.
The adjustable bladeless fan structure is characterized in that the base is connected with the wind ring, and the respective structures of the base and the wind ring and the mutual connection structure are changed. The motor in the base rotates, drives the flabellum and rotates, produces the amount of wind, and the amount of wind passes through the filter core, gets into the base periphery, then gets into the wind ring, blows off from the air outlet of wind ring again. The setting of locating plate, on the one hand, plays the effect of sheltering from to filter core upper portion, avoids the amount of wind to spill, and on the other hand sets up accommodate motor on the locating plate, and during accommodate motor's pivot rotated, drive the lead screw and rotate, and the lead screw is twisted the silk hole that the dress passed the silk hole piece of the closure plate in the wind ring lower part. The locating piece activity card dress on base upper portion realizes the spacing of base and wind ring in the constant head tank in the wind ring outside, ensures that the wind ring can not rotate for the base, and only can drive the wind ring when the lead screw rotates for the base altitude variation, air outlet altitude variation promptly. When the fan is placed on the ground of bedside and used, the height of the bladeless fan can be effectively improved on the premise that the fan can normally work, the height of the bladeless fan is adapted to the heights of different beds, the air outlet of the bladeless fan cannot be shielded by the beds, air volume loss is avoided, and the utilization rate is improved. The adjustable bladeless fan structure is convenient and reliable to operate, when the fan is placed on the ground beside a bed for use, the height of the bladeless fan can be effectively increased on the premise that the fan can work normally, the height of the bladeless fan can be adapted to heights of different beds, an air outlet of the bladeless fan cannot be shielded by the beds, air volume loss is avoided, the utilization rate is effectively increased, and the using effect of the bladeless fan is improved.
