[0009] By adopting the above technical solution, when the shell is assembled, the upper cover is snapped onto the lower cover, and then the stepped skirt on the lower cover is inserted into the plug-in groove of the upper cover to limit the upper cover and the lower cover from disengaging. Then, the upper cover and the lower cover are fastened together at the first air outlet through the end cover, thereby achieving the effect of fastening both ends of the upper cover and the lower cover at the same time, thereby improving the fastening stability and sealing.

[0010] The above technical solution is further configured as follows: a first sealing strip is installed at the bottom of the plug-in slot.

[0011] By adopting the above technical solution, the first sealing strip is installed at the bottom of the plug-in slot, and the stepped skirt squeezes the first sealing strip, so that the sealing performance can be further improved.

[0012] The above technical solution is further configured as follows: the upper cover has step convex ribs on both side edges, the lower cover has snap-fitting grooves on both side edges that snap-fit ​​with the step convex ribs, and a second sealing strip is installed at the bottom of the snap-fitting groove.

[0013] By adopting the above technical solution, the stepped convex rib of the upper cover is inserted into the clamping groove of the lower cover to achieve a fastening connection, and a second sealing strip is installed at the bottom of the clamping groove, which can further improve the sealing performance.

[0014] The above technical solution is further configured as follows: the upper cover and the lower cover are provided with external threads on the outer sides of the arc-shaped openings at the first air outlet, and the end cover is provided with internal threads matching the external threads.

[0015] By adopting the above technical solution, the upper cover and the lower cover are fastened at the first air outlet by threaded connection with the end cover, and the threaded structure is easy to disassemble and assemble and is firm and reliable.

[0016] The above technical solution is further configured as follows: installation notches are provided on both sides of the lower cover, and a unit fixing installation position is provided on the bottom.

[0017] By adopting the above technical solution, the installation notch and the fixed installation position of the unit are used for fixed installation and positioning of the internal components of the heater.

[0018] The beneficial effects achieved by the utility model are: the entire shell is easy to assemble and beautiful, and has fastening stability and good sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS
