the air inlet assembly of the embodiment is designed and developed for solving the problem of oxygen supplement of the inner container of the kitchen garbage treatment device. Referring to fig. 1 to 4, the air intake assembly includes an inner container 1, an air intake duct 2 and an air intake fan 3, the inner container 1 is provided with a holding cavity for holding the biodegradable material and the kitchen waste, a first air exhaust outlet 11 and an air intake opening 12 are provided on the wall surface of the inner container 1, and the first air exhaust outlet 11 is used for exhausting the waste gas in the holding cavity; the air inlet duct 2 is arranged on the wall surface of the inner container 1, an air inlet faces the inner part of the inner container 1, and the air inlet duct is communicated with the air inlet 12; the air inlet fan 3 is arranged on the outer side of the inner container 1, and an air outlet of the air inlet fan 3 is communicated with the air inlet port 12 and used for conveying air to the air inlet duct 2 through the air inlet port 12 so as to realize air inlet of the accommodating cavity of the inner container 1. In the process that the biological decomposition material in the holding cavity of the inner container 1 decomposes kitchen garbage, a large amount of waste gas is generated, the waste gas is discharged through the first air outlet 11, if the air is not supplemented to the holding cavity of the inner container 1 in time, negative pressure can be generated in the holding cavity of the inner container 1, when the waste gas generated in the inner container 1 is discharged through the first air outlet 11, the air inlet fan 3 is started, the outside air enters the air inlet 12 under the action of the air inlet fan 3 and then enters the air inlet duct 2 through the air inlet duct 12, then the air flows through the air inlet duct 2 and enters the holding cavity of the inner container 1, oxygen is supplemented to the biological decomposition material in the holding cavity of the inner container 1, and the air pressure in the holding cavity of the inner container 1 is balanced.

Referring to fig. 2 and 4, in this embodiment, the air inlet duct 2 includes a duct body and sidewalls connected to the upper, left and right sides of the duct body, the sidewalls above the duct body are respectively connected to the sidewalls on the left and right sides of the duct body, the sidewalls on the left and right sides of the duct body are perpendicular to the duct body, a fixing column is disposed on one side of the duct body close to an inner wall surface of the liner 1 connected to the duct body, the fixing column is adapted to the sidewalls on the left and right sides of the duct body, and is connected to the inner wall surface of the liner 1 to enable the sidewalls above, left and right sides of the duct body to abut against the inner wall surface of the liner 1 and to be hermetically connected to the inner wall surface of the liner 1. When the air inlet duct 2 is connected with the wall surface of the inner container 1, the air inlet duct 2 is connected with the wall surface of the inner container 1 through the fixing column, and further the air duct body is fixed on the wall surface of the inner container 1, when the air duct body is fixed on the wall surface of the inner container 1, the side walls of the upper end, the left side and the right side of the air duct body are tightly attached to the wall surface of the inner container 1 and are in sealing connection with the wall surface of the inner container 1, an air outlet of the air inlet duct 2 is formed by an opening between the lower end of the air duct body and the wall surface of the inner container 1, under the action of the air inlet fan 3, outside air enters the air inlet duct 12 through the air outlet of the air inlet fan 3 and then enters the air inlet duct 2 through the air inlet duct 12, and the air entering the air inlet duct 2 flows along a gap between the air duct body and the wall surface of the inner container 1 and flows out through a gap between the lower end of the air duct body and the wall surface of the inner container 1.

Referring to fig. 7 and 8, in particular, in application, a U-shaped groove recessed toward the upper surface of the chassis 5 is formed on the lower surface of the chassis 5, an exhaust cover plate 514 matched with the U-shaped groove is disposed on the U-shaped groove, the exhaust cover plate 514 is matched with the U-shaped groove and divides the U-shaped groove into a first section, a second section and a middle transition section, the first section forms a first air duct 511, the second section forms a second air duct 512, a connection port 513 is disposed on a portion of the U-shaped groove located at the first section, the exhaust fan 6 is fixed on the chassis 5, an air outlet of the exhaust fan 6 is aligned with and connected to the connection port 513, the connection port 513 is communicated with an air outlet of the exhaust fan 6, a portion of the exhaust cover plate 514 located at the first section is shorter than a portion of the U-shaped groove located at the second section, and a second exhaust outlet 52 is formed at the second section. When the air is exhausted from the air outlet of the exhaust fan 6, the air enters the connection port 513 through the outlet of the exhaust fan 6, then enters the first section (the first air duct 511) through the connection port 513, then flows along the first section, enters the second section (the second air duct 512) through the middle transition section (the bent section), moves along the second air duct 512, and finally is exhausted from the second exhaust outlet 52.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
