Through the arrangement mode, when the air inlet grille 2 is installed, the first side of the air inlet grille 2 can be connected with the shell 1 through the first connecting piece 3, then the air inlet grille 2 rotates along the anticlockwise direction, and then the second side of the air inlet grille 2 is fixedly connected with the shell 1 through the second connecting piece 5 in a magnetic adsorption mode; when the air inlet grille 2 needs to be opened to overhaul internal components, external force can be applied to remove the connection between the second connecting piece 5 and the shell 1, then the air inlet grille 2 is rotated clockwise, so that a certain angle can be formed between the air inlet grille 2 and the shell 1, and a local area in the shell 1 can be exposed in the environment, so that the internal components can be overhauled without detaching the air inlet grille 2. That is, as shown in fig. 2, the air grille 2 is in a horizontal state, in which the air grille 2 is mounted, and in a vertical state, in which the air grille 2 is opened. If the grille 2 needs to be removed for cleaning, the first connector 3 needs to be further disconnected from the housing 1.

In this embodiment, the casing 1 is made of a metal plate, so that when the second side of the air inlet grille 2 equipped with the magnetic component is close to the casing 1, the air inlet grille 2 can be attracted with the casing 1 under the action of the magnetic component, thereby realizing the fixed connection between the second side of the air inlet grille 2 and the casing 1. Obviously, the housing may also be made of sheet metal only in the portion facing the second side of the air intake grille or in the portion corresponding to the second connection member.

Certainly, the second side of the air inlet grille can also be connected with the shell in other arrangement modes, such as possible connection modes of clamping connection or screw connection, and the like, and a person skilled in the art can flexibly select the connection mode of the second side and the shell according to a specific application scene so as to adapt to a more specific application occasion.

With continued reference to fig. 3 to 12 and in accordance with the orientation shown in fig. 3, the first connecting member 3 comprises a base body having a substantially U-shaped configuration formed by a transverse portion 32 and two vertical portions 31 at both ends of the transverse portion 32, and a pivot portion provided on the vertical portions 31 of the base body, wherein the pivot portion includes a first sub-end and a second sub-end, a first pin 311 as the first sub-end is provided at the upper end of the vertical portion 31 on the left side, and a second pin 312 as the second sub-end is provided at the upper end of the vertical portion 31 on the right side. It is obvious that the pivot part may also comprise only one sub-end.

Accordingly, as shown in fig. 4 and 5, the air intake grill 2 is formed with a notch 21 at a position corresponding to the first connecting member, and the left and right sides of the notch 21 are formed with shaft holes 211 at positions corresponding to the first pin 311 and the second pin 312.

Through such setting, when installing first connecting piece 3 to air-inlet grille 2, insert first round pin axle 311 earlier in left shaft hole 211, exert external force and make the U-shaped structure produce inside deformation, then insert second round pin axle 312 in the shaft hole 211 on right side, remove external force, the U-shaped structure reconversion under self elastic action to can set up first connecting piece 3 in air-inlet grille 2 better.

With continued reference to fig. 3 to 12 and in accordance with the orientation shown in fig. 3, a connection portion is provided on the transverse portion 32, the connection portion includes a snap-fit structure, the housing 1 is formed with a flange 11 at a position corresponding to the air intake grille 2, the flange 11 is formed with a snap-fit hole 111 at a position corresponding to the first connecting member 3, and the first connecting member 3 can be fixedly connected to the housing 1 by abutting the flange 11 at a position corresponding to the snap-fit hole 111 against the snap-fit structure.

Specifically, as shown in fig. 3, the transverse portion 32 is provided with an elastic buckle 321 as a clamping member, the elastic buckle 321 is disposed in the middle of the transverse portion, and the height of the elastic buckle 321 is lower than the first pin 311 and the second pin 312, so that the first connecting member 3 is not interfered with the installation of the first connecting member 3 to the air intake grille 2 through the first pin 311 and the second pin 312.

As shown in fig. 3, the outer edges of the left and right vertical portions 31 are extended forward with a first reinforcing rib 313 and a second reinforcing rib 314, respectively, to reinforce the strength of the first connecting member 3. Obviously, the first reinforcing rib and the second reinforcing rib can also extend backwards along the outer edges of the two vertical parts, and a person skilled in the art can flexibly select the first reinforcing rib and the second reinforcing rib according to a specific application scene so as to adapt to a more specific application occasion.

Obviously, the third reinforcing rib and the fourth reinforcing rib may not be connected to the first reinforcing rib and the second reinforcing rib, and the embodiment is not limited.

With the above arrangement, the first connecting member 3 is pivotally connected to the air intake grille 2 by the first pin 311 and the second pin 312 disposed on the vertical portion 31, and the first connecting member 3 is fixedly connected to the housing 1 by the first docking structure 3211, the second docking structure 317 and the third docking structure 318 disposed on the lateral portion 32, so that the air intake grille 2 can be pivotally disposed on the housing 1 by the first connecting member 3.

With this arrangement, when the second connecting member 5 is installed, the second connecting member 5 is first placed in the accommodating sub-cavity of only the first portion 41, then the protruding end 414 on the left side is inserted into the clamping hole 422 on the left side, and then the screw 43 passes through the through hole 4141 and the positioning hole 4211 in sequence so as to fixedly connect the protruding end 414 on the right side with the air inlet grille 2, so that the second connecting member 5 is also disposed on the lower surface of the air inlet grille 2. Obviously, both protruding ends of the body can be connected with the air inlet grille through fasteners (such as screws and the like).

It is understood that the mounting member may be connected to the air intake grille by other means, such as adhesion, magnetic adsorption, or screw connection, and those skilled in the art can flexibly select the fixing manner of the mounting member on the air intake grille according to the specific application scenario so as to adapt to more specific application occasions.

The first sub end and the second sub end of the pivoting part are respectively arranged on the vertical part of the base body and are in pivoting connection with the air inlet grille, the connecting part is arranged on the transverse part of the base body, and the base body is provided with a clamping structure fixedly connected with the shell, so that the air inlet grille is arranged on the shell in a pivoting mode through the first connecting piece. The clamping structure formed by the first butt joint structure arranged on the clamping piece, the second butt joint structure arranged on the vertical part and the third butt joint structure is used for connecting the part of the shell corresponding to the first connecting piece with the clamping structure, so that the clamping of the connecting part and the shell is realized.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
