The invention relates to a low-temperature non-combustion smoking set and a cleaning method thereof. The low-temperature non-combustion smoking set comprises a smoking set body, a clamping piece and an opening assembly. An air inlet channel and an air outlet channel are formed in the smoking set body, and the air inlet channel is communicated with the air outlet channel; the clamping piece is clamped to the smoking set body and shields the air inlet channel, the clamping piece is provided with an air inlet hole, and the air inlet hole is communicated with the air inlet channel; the opening assembly is connected with the smoking set body, and the opening assembly can abut against the clamping piece to push the clamping piece, so that the clamping piece is separated from the smoking set body and the air inlet channel is exposed. After the clamping piece and the smoking set body are separated, the air inlet channel can be exposed, and the air inlet channel can be effectively cleaned by means of a brush and other cleaning tools. The low-temperature non-combustion smoking set is simple in structure and easy to operate, and the air inlet channel can be conveniently cleaned so that the air inlet channel can be prevented from being contaminated.
