[0021] In the desktop heater with the above structure, during assembly and installation, the user first assembles the fan 5 and PTC heating element 6 using the mounting mechanism 7. Then, the mounting mechanism 7 installs and fixes the assembled fan 5 and PTC heating element 6 inside the front housing 1, allowing the parts of the desktop heater to be reasonably assembled and installed, reducing its size. Then, the front housing 1 is fixed to the rear housing 2 by the fixing part 8. Compared with the prior art, this method can reasonably assemble and install the heater parts, reduce the overall size of the heater, speed up the assembly of the heater, and improve production efficiency.

[0022] like Figure 4 As shown, in some embodiments of this utility model, a support housing 11 extends from the front side of the front housing 1, an air inlet grille 12 is provided on the support housing 11, a wire hole 13 is provided below the air inlet grille 12 on the front side of the support housing 11, and a handle 14 is provided above the support housing 11. The fan 5 draws outside air into the front housing 1 through the air inlet grille 12. When the user places the heater, the support housing 11 supports the heater as a whole and places it in the desired position. When the user picks up the handle 14, the heater is moved to the desired position.

[0023] like Figure 3As shown, in some embodiments of this utility model, the mounting mechanism 7 includes a first docking housing 71 fixedly installed inside the front housing 1. The first docking housing 71 has a through groove 72 that communicates with the mounting port 3. A second docking housing 73 is installed inside the front housing 1 on the front side of the first docking housing 71. The first docking housing 71 has insertion ears 711 on its left and right sides.
