The utility model provides a dual-purpose fan, refers to fig. 1 to 4, includes frame 1 and locates screen panel 2 on frame 1, the rotation of screen panel 2 is connected with flabellum 4, install positive reverse motor 11 in the screen panel 2, one side of fan is equipped with heating element.

The utility model discloses a dual-purpose fan, which is characterized in that the fan passes through a fan blade 4 arranged in a mesh enclosure 2, and the fan blade 4 realizes positive and negative bidirectional rotation through a positive and negative rotation motor 11, so that air can be blown no matter the fan blade 4 rotates positively or negatively; on the basis of the forward and reverse rotation air outlet of the fan blade 4, the heating component is installed on one side of the fan blade 4, and under the application of the heating component, the fan can be used for cooling in hot summer and heating in cold winter, so that the multifunctional application of the fan is realized.

Further, the fan blade 4 is provided with a positive blade, the back of the positive blade is provided with an auxiliary blade, and the rotation directions of the positive blade and the auxiliary blade are opposite.

Because flabellum 4 can realize positive and negative aspect air-out under the rotation of positive reverse motor 11, further, at the positive blade that this flabellum 4 set up, the back of positive blade is provided with the auxiliary blade, and this positive blade and this auxiliary blade direction of rotation are opposite for flabellum 4 reverse side air-out is more powerful.

Further, still including locating controller 3 on frame 1, positive reverse motor 11 with heating element respectively with the input electricity of controller 3 is connected, controller 3 is equipped with signal reception module.

This dual-purpose fan is still equipped with controller 3 on frame 1, the utility model discloses a 3 models of controller be AT80C51 type singlechip. On the one hand, the switching application of the motor 11 and the heating component which are controlled to rotate forwards and reversely is convenient, and on the other hand, the infrared signal receiving module is arranged on the controller 3, so that people can remotely control the function switching of the electric fan, and the intelligent operation is realized.

Further, the heating component is detachably mounted in the mesh enclosure 2. The heating component is convenient to be manually disassembled and assembled.

Further, the heating element is provided with a plurality of fixing columns 81, the mesh enclosure 2 is provided with a plurality of fixing cylinders 6 which are matched with the fixing columns 81 in an inserted manner, and a locking element 8 for locking and unlocking the fixing columns 81 is arranged between the fixing columns 81 and the fixing cylinders 6.

The insertion fit of the fixing post 81 and the fixing barrel 6 is a common technical means, so that the fit mode is very easy to realize and the operation is relatively simple.

Further, the locking assembly 8 comprises a sliding groove 82 arranged in the fixed cylinder 6, the sliding groove 82 is connected with an insert block 83 in a sliding manner, a spring 84 is connected between the insert block 83 and the bottom of the sliding groove 82, an insert groove for inserting and matching the insert block 83 is arranged on the inner wall of the fixed cylinder 6, and the end part of the insert block 83 is in a conical shape; in the natural state of the spring 84, the conical end of the insert 83 protrudes out of the sliding groove 82.
