Disclosed are an electronic cigarette device, an electronic cigarette and an atomization device thereof. The atomization device comprises an atomization base (14), and an atomizer (12) provided with an electric heating wire (121) and located at one side of the atomization base (14). The other side of the atomization base (14) facing away from the atomizer (12) is provided with a first electrode assembly (30). The first electrode assembly (30) comprises a first base body (31) and a first electrode post (32) which are insulated from each other and respectively connected to both ends of the electric heating wire (121) to form a positive and negative electrode of the atomizer (12). The first base body (31) and the atomization base (14) are butted with each other and a first end of the electric heating wire (121) is sandwiched therebetween, and the first electrode post (32) and the atomization base (14) are butted with each other and a second end of the electric heating wire (121) is sandwiched therebetween. As a result of the mutual extrusion between the atomization base (14) with the first electrode assembly (30) and an atomization sleeve (13), the electric heating wire (121) of the electronic cigarette is fixed, the structure is stable, and the electric heating wire is directly connected to the electrode assembly without welding.
