Cooling or heating fan magnetically attachable to metal board

Abstract

The present invention provides a cooling or heating fan magnetically attachable to a metal board. The cooling or heating fan has a disk-form or stand-form base whose lower surface is provided with a plurality of strong permanent magnets so as to magnetically attach the cooling or heating fan to iron-made partitions, furniture or structures for convenient use.

1 . A cooling or heating fan magnetically attachable to a metal board, mainly having a bottom plate  12  of a disk-form base  11  of the cooling or heating fan  1  provided with a plurality of recesses  121  that fixedly receives therein strong permanent magnets M, so that the cooling or heating fan  1  with the disk-form base  11  is allowed to be not only placed on a floor or a table but also magnetically attach to an iron-made wall W or an iron-made device surface for use. 
     
     
         2 . A cooling or heating fan magnetically attachable to a metal board , mainly having a stand-form base  21  of the cooling or heating fan  2  provided with a plurality of rubber pads  22  clipping the stand-form base  21 , and each of the rubber pads  22  receiving therein a strong permanent magnet M, so that the cooling or heating fan  2  with the stand-form base  21  is allowed to be not only placed on a floor or a table but also magnetically attach to an iron-made wall W or an iron-made device surface for use. 
     
     
         3 . The cooling or heating fan of  claim 1 , wherein the disk-form base  11  of the cooling or heating fan  1  is provided with a socket  111 , for receiving a positioning plate  16  that is formed with a plurality of positioning holes  161 , and at least one positioning ball  162  and at least one spring  163  are placed on the positioning holes  161  before the post  14  and the disk-form base  11  are screwedly assembled, so that a blowing angle of the cooling or heating fan  1  with the disk-form base  11  can be adjusted.
