Problems solved by technology
This not only wastes money, but also takes up a lot of space and causes a lot of inconvenience
At the same time, most of the existing fans are fixed at a certain position by clips or bases, and people need to be close to the fans to cool off or heat
This greatly restricts people's freedom and is not conducive to the flexible use of fans

The invention discloses a convenient-to-use cooling and heating fan which comprises a shell 7, an air inlet 8 formed in the top end of the shell 7, a cold-blast air draught fan 5, a cold-blast air outlet 9, a control panel 1 arranged in the shell, a battery 2, a semiconductor heating / refrigerating device 4, as well as a hot-blast air draught fan 3 and a hot-blast air outlet 6 at the bottom of theshell; the cold-blast air draught fan 5, the semiconductor heating / refrigerating device 4, the battery 2 and the hot-blast air draught fan 3 are electrically connected with the control panel 1; a shifting button 10 is further arranged on the control panel 1 and comprises a first gear, a second gear and a third gear; the first gear is used for starting the cold-blast air draught fan 5 and the semiconductor heating / refrigerating device 4 for refrigeration to generate cold-blast air; the second gear is used for starting the hot-blast air draught fan 3 and the semiconductor heating / refrigerating device 4 for heating to generate hot-blast air; the third gear is used for starting the cold-blast air draught fan 5 to generate natural wind; and a button hole 11 allowing one end of the shifting button to extend out of the shell 7 is formed in the shell 7. The convenient-to-use cooling and heating fan is convenient to use and carry.
Description
technical field [0001] The invention relates to a fan, in particular to a convenient cooling and heating fan. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for fans are also getting higher and higher. At present, there are mainly two types of fans on the market, i.e. cooling fans and heating fans. The cooling fan is mainly used for enjoying the cool when the weather is hot, and the hot fan is mainly used for heating when the weather is cold. However, it is often necessary to buy these two fans at the same time to meet the needs of cooling and heating. This not only wastes money, but also takes up a lot of space and causes a lot of inconvenience. At the same time, most of the existing fans are fixed at a certain position by clips or bases, and people need to be close to the fans to enjoy the cool or to keep warm. This restricts people's freedom to a great extent and is not conducive to the flexible use of...
