In the embodiment of the utility model, as shown in fig. 1 to 4, the blower comprises a shell 10, a main control board 61, a fan assembly 40, a ceramic heating body 20 and a power supply battery 30, wherein the shell 10 is provided with an air inlet 101, an air outlet 102 and an air supply channel 103 positioned between the air inlet 101 and the air outlet 102, the main control board 61 is arranged in the shell 10, the fan assembly 40 is arranged in the air supply channel 103, the fan assembly 40 is used for driving air to enter the air supply channel 103 from the air inlet 101 and then flow out from the air outlet 102, the ceramic heating body 20 is arranged in the air supply channel 103, the ceramic heating body 20 is used for heating the air flowing through the air supply channel 103, and the fan assembly 40 and the ceramic heating body 20 are electrically connected with the main control board 61.

The power supply battery 30 is arranged on the shell 10, the power supply battery 30 is electrically connected with the main control board 61, and the power supply battery 30 is used for providing electric energy for the main control board 61 so as to control the fan assembly 40 and the ceramic heating body 20 to work through the main control board. When in use, the main control board 61 is powered by the power supply battery 30, so that the blower is not in use by being plugged in all the time, and the blower is convenient for a user to use in a moving way.

Specifically, the ceramic heating element 20 is a heating structure, that is, at least two wiring parts 21 with intervals are arranged on the ceramic heating element 20, the main control board 61 is connected through the wiring parts 21, one wiring part 21 is used for connecting the positive electrode of a power supply, the other wiring part 21 is used for connecting the negative electrode of the power supply, after the power supply is connected, current flows through the ceramic heating element 20, so that electric energy is converted into heat energy, heat is transferred to the surface of the ceramic heating element 20, and when airflow flows through the ceramic heating element 20, the airflow and the ceramic heating element 20 can exchange heat, so that the airflow flowing through the ceramic heating element 20 can be heated. Compared with the heating wire, the ceramic heating element 20 has high heating efficiency, can lead the size of the ceramic heating element 20 to be smaller, thereby reducing the occupied space of the ceramic heating element 20 in the blower, and the ceramic heating element 20 can not be fused even if being used for a long time, and has longer service life.

And compared with the heating wire, when the ceramic heating body 20 is adopted for heating, the heating efficiency of the ceramic heating body 20 is high, the energy consumption is low, and when the power supply battery 30 is adopted for supplying power, the duration of the blower can be longer, so that the blower can be conveniently used by users in more scenes such as outdoors, power failure and the like.

In some embodiments, the ceramic heating body 20 has a ring shape and has two wiring portions 21 and two heating portions 22 connected between the two wiring portions 21, the two heating portions 22 being symmetrically disposed about a line connecting the two wiring portions 21.
