In some embodiments, fastening holes 2351 are formed in the connecting studs 235, and it should be noted that after the front cover 23 is positioned by the positioning portions 113, through holes of the machine head shell 10 for the fasteners 30 to pass through are aligned with the fastening holes 2351, and the fasteners 30 pass through the machine head shell 10 and are screwed into the fastening holes 2351 of the connecting studs 235, so as to fix the machine head shell 10.

In some embodiments, the hook 223 is formed at the end of the back cover 22 in the length direction, and another corresponding hook 223 is formed on a connecting stud 235 of the front cover 23, so that the two hooks 223 are engaged to improve the reliability of the connection between the front cover 23 and the back cover 22.

Illustratively, referring to fig. 3 and 4, the cover plate 12 includes an inner plate 121 and a waterproof outer plate 122, and the inner plate 121 is detachably disposed at the window 112. One side of the waterproof outer plate 122 facing the inner plate 121 is provided with a buckle support 123, the inner plate 121 is provided with a buckle groove 1211, and the buckle support 123 is clamped at the buckle groove 1211, so that the waterproof outer plate 122 seals the window 112, thereby preventing water from entering the accommodating cavity 111 to a certain extent, and the waterproof outer plate 122 is not required to be provided with a mounting hole, so that a better waterproof effect is achieved.

It is understood that the structure of the waterproof outer plate 122 is not limited, and in some embodiments, the waterproof outer plate 122 is a see-through glass plate, and the surface of the inner plate 121 facing the waterproof outer plate 122 is patterned. At this time, the inner panel 121 serves as a decorative panel, and the pattern thereof can be displayed through the waterproof outer panel 122 made of glass, which is excellent in visual effect.

In this embodiment, the inner plate 121 is fixed to the housing 11 by a fastener. It should be noted that, when a partial area of the inner plate 121 is pressed under the cover 41 of the drying box, the cover 41 of the drying box can be directly removed by hand, and the installation and the disassembly of the inner plate 121 are not affected.

It is understood that the specific structure of the buckle holder 123 is not limited, and for example, the buckle holder 123 includes an elastic portion 1231, an abutting portion 1232, and a connecting portion 1233 connecting the elastic portion 1231 and the abutting portion 1232. The connecting portion 1233 is fixed to a surface of the waterproof outer panel 122 facing the inner panel 121, and the elastic portion 1231 and the abutting portion 1232 protrude from a surface of the waterproof outer panel 122 facing the inner panel 121. The waterproof outer plate 122 covers the inner plate 121, the abutting portion 1232 abuts against one side wall of the fastening groove 1211, and the elastic portion 1231 elastically deforms to abut against the other side wall of the fastening groove 1211, so that the fastening bracket 123 and the fastening groove 1211 maintain a pre-tightening force, and the waterproof outer plate 122 is stably fixed on the inner plate 121. Here, the snap bracket 123 can be detached from the snap groove 1211 against the biasing force by hand, and the waterproof outer plate 122 can be easily detached.

In some embodiments, one end of the elastic portion 1231 is connected to the connecting portion 1233, the elastic portion 1231 extends toward a direction away from the waterproof outer panel 122, and an included angle between the elastic portion 1231 and the connecting portion 1233 is an obtuse angle, when the elastic portion 1231 is pressed into the fastening groove 1211, the elastic portion 1231 is pressed by the sidewall of the fastening groove 1211 and elastically deforms toward the retaining portion 1232, so that a pre-tightening force is generated between the fastening bracket 123 and the fastening groove 1211 to fix the waterproof outer panel 122.

In order to avoid the interference between the elastic portion 1231 and the other side wall of the fastening groove 1211 during the installation process, in some embodiments, one end of the elastic portion 1231 away from the connecting portion 1233 is bent away from the other side wall of the fastening groove 1211.

In some embodiments, a portion of the abutting portion 1232 abuts against a side wall of the fastening groove 1211, and a portion of the abutting portion is bent and extended to a surface of the inner plate 121 facing away from the waterproof outer plate 122, so as to improve the resistance of the waterproof outer plate 122 and the fastening bracket 123 against being separated from the fastening groove 1211 upwards.

In some embodiments, the snap bracket 123 is an integrally formed sheet metal part. The snap bracket 123 is fixed by gluing to the side of the waterproof outer plate 122 facing the inner plate 121.
