[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 7 As shown, the utility model provides a tower fan which is convenient for cleaning and replacing the filter, comprising a fan body 1, a connecting plate 2 being fixedly connected to the rear surface of the fan body 1, a mounting plate 4 being movably connected to the inner surface between the fan body 1 and the connecting plate 2, a filter 5 being fixedly mounted on the inner surface of the mounting plate 4, a stopper 3 being fixedly connected to the outer surface of the stopper 3 and the outer surface of the mounting plate 4 being movably connected, a fixing block 6 being fixedly connected to the upper and lower sides of the left surface of the fan body 1, a fixing rod 7 being fixedly sleeved on the inner surface of the fixing block 6, and a fixing rod 7 being movably sleeved on the outer surface of the fixing rod 7 The movable plate 8 on the inner side of block 6, the outer surface of the movable plate 8 is fixedly connected with an insertion rod 13, the other end of the insertion rod 13 passes through the mounting plate 4 and extends to the outside of the mounting plate 4, the outer surface of the insertion rod 13 and the inner surface of the mounting plate 4 are movably connected, the left surface of the fan body 1 is fixedly installed with the No. 1 motor 9 located on the front side of the movable plate 8, the other end of the output shaft of the No. 1 motor 9 is fixedly sleeved with the No. 1 circular shaft 10, the outer surface of the No. 1 circular shaft 10 is fixedly sleeved with a driving rod 11, the inner surface of the other end of the driving rod 11 is fixedly sleeved with a cylinder 12, and the outer surface of the cylinder 12 and the inner surface of the movable plate 8 are movably connected.

[0026] When the No. 1 motor 9 is running, the No. 1 circular shaft 10, the driving rod 11, and the cylinder 12 will all start to rotate. At this time, due to the rotation of the cylinder 12, the movable plate 8 and the insertion rod 13 will start to move together under the drive of the cylinder 12, and eventually the insertion rod 13 will be moved out from the inside of the mounting plate 4.

[0027] Among them, the top of the inner surface of the fan body 1 is movably connected to a hollow box 14, the upper surface of the hollow box 14 is fixedly connected to a cover plate 15, the lower surface of the cover plate 15 is movably connected to the upper surface of the fan body 1, and the upper surface of the cover plate 15 is fixedly connected to a handle 16.

[0028] The design of the hollow box 14 , the cover plate 15 and the handle 16 makes it easy for the operator to pull the hollow box 14 out of the interior of the fan body 1 as a whole.

[0029] Among them, the left and right sides of the inner surface of the hollow box 14 are movably connected with a block 25, and the number of the block 25 is two. The outer ends of the two blocks 25 pass through the hollow box 14 and the fan body 1 in sequence and extend to the outside of the fan body 1. The outer surfaces of the front and rear sides of the two blocks 25 are fixedly connected with a connecting block 29, and the outer surface of the connecting block 29 is fixedly connected with a spring 30. The other end of the spring 30 is fixedly connected to the inner surface of the hollow box 14.

[0030] When the block 25 is not squeezed by the outer surface of the movable plate 8 , the block 25 as a whole will begin to move toward the inside of the hollow box 14 under the elastic force of the spring 30 , so that the block 25 automatically breaks away from the contact with the inner surface of the fan body 1 .

[0031] A second motor 26 is fixedly mounted on the middle portion of the lower surface of the cover plate 15 , and a rotating shaft 27 is fixedly sleeved on the other end of the output shaft of the second motor 26 .

[0032] When the second motor 26 is running, the rotating shaft 27 starts to rotate.

[0033] A cam 28 is fixedly sleeved on the outer surface of the rotating shaft 27 , and the left and right sides of the outer surface of the cam 28 are movably connected to the outer surfaces of the two clamping blocks 25 respectively.

[0034] The rotation of the cam 28 squeezes the block 25 so that the block 25 is inserted into the inner surface of the sector 1 , thereby achieving the fixation of the hollow box 14 as a whole.

[0035] Among them, the lower surface of the hollow box 14 is fixedly connected to a fixed round block 17, the lower surface of the fixed round block 17 is fixedly connected to a limiting sleeve 18, the inner surface of the limiting sleeve 18 is movably connected to a pulling round block 19, and the lower surface of the pulling round block 19 is fixedly connected to the fan blade 20 located inside the fan body 1.

[0036] The design of the fan blades 20 ensures that the fan blades 20 do not generate high-volume wind noise when rotating to supply air, thereby ensuring that the fan body 1 as a whole can remain quiet during operation.

[0037] A reduction motor 21 is fixedly mounted on the bottom of the inner surface of the fan body 1 , a drive shaft 22 is fixedly sleeved on the other end of the output shaft of the reduction motor 21 , and a transmission sleeve 23 is fixedly sleeved on the outer surface of the drive shaft 22 .

[0038] The operation of the reduction motor 21 causes the drive shaft 22 and the transmission sleeve 23 to start rotating.

[0039] The inner surface of the transmission sleeve 23 is movably connected to a connecting block 24 , and the upper surface of the connecting block 24 is fixedly connected to the lower surface of the fan blade 20 .

[0040] The design of the transmission sleeve 23 and the connecting block 24 allows the connecting block 24 and the fan blade 20 to rotate together with the transmission sleeve 23 .

[0041] The working principle and use process of this utility model:

[0042] When there is a lot of dust attached to the outer surface of the filter 5, the operator starts the No. 1 motor 9. As the No. 1 motor 9 runs, the No. 1 circular shaft 10, the driving rod 11 and the cylinder 12 will rotate. During this process, the movable plate 8 will move forward driven by the cylinder 12 and limited by the fixed rod 7, which will cause the insertion rod 13 to gradually begin to separate from the inner surface of the mounting plate 4. Finally, when the insertion rod 13 no longer has direct contact with the mounting plate 4, the overall fixation of the mounting plate 4 will be released. At this time, the operator can directly pull out the mounting plate 4 as a whole for cleaning or replacement.

[0043] When the operator needs to clean or replace the fan blade 20 as a whole, the operator first starts the No. 2 motor 26. As the No. 2 motor 26 runs, the rotating shaft 27 and the cam 28 will start to rotate so that the cam 28 will be out of contact with the block 25. At this time, the two blocks 25 will move toward each other along the inner surface of the hollow box 14 under the elastic force of the spring 30. Finally, when the block 25 no longer contacts the inner surface of the fan body 1, the fixation of the hollow box 14 by the block 25 will be released. At this time, the operator can first remove the hollow box 14 as a whole, and then pull out the pulling block 19 and the fan blade 20 as a whole.

[0044] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
