Embodiment Construction
[0022] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, this embodiment does not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to this embodiment are included in the protection scope of the present invention.
[0023] Such as figure 1 and figure 2 As shown, the fan structure for a cigarette filter provided by the present invention includes an impeller 100 and a support member 200 . The impeller 100 has a shaft sleeve 11 and a plurality of fan blades 12 formed on the outer periphery of the shaft sleeve 11; The inner connecting rod 23.
[0024] to combine image 3 and Figure 4 As shown, the bushing 11 is formed with a shaft hole 111 that penetrates front and back to fit and assemble with the central shaft 22, and the bushing 11 includes a main body portion 112 that is adjacent in the axial direction and is integr...

Abstract
The invention provides a fan structure used for a cigarette filter tip. The fan structure comprises an impeller and a supporting member, and the impeller is provided with a shaft sleeve and a plurality of blades on the periphery of the shaft sleeve; the supporting member is provided with a shell, a central shaft and connecting rods which are fixedly arranged in the shell. A gas flow channel running through the front and the back is formed in the shell; the central shaft comprises a shaft rod and a supporting part which are arranged front and back in sequence in the axial direction; the shaft sleeve and the shaft rod are arranged in a spaced mode, and the supporting part is gradually increased from front to back in the radial direction until to exceed the inner diameter of the shaft sleeve.By means of the fan structure, the surface of the supporting part has a certain inclination angle relative to the axial direction of the impeller so that the impeller can rotate under the action of small gas flow; the kinetic friction force between the rear end of the shaft sleeve and the surface of the supporting part is small, so that the rotating speed of the impeller is increased; the inertial rotation duration of the impeller can be prolonged, and after the gas flow disappears, the impeller can still continuously rotate for 1.2-2.0 s.
Description
technical field [0001] The invention relates to the technical fields of injection molding and cigarettes, in particular to a fan structure used for cigarette filters. Background technique [0002] With the improvement of residents' consumption level, the consumption demand of cigarettes also continues to grow. Consumers' requirements for the taste of cigarettes are increasing day by day, and they are paying more and more attention to the hazards of smoke and their own health. In order to keep innovating in aspects such as cigarettes, it is necessary to innovate in the structure of cigarettes in order to cope with domestic and foreign industry competition and consumer demand. The patent document CN105595419A discloses a new type of cigarette mouthpiece, which includes a primary filter rod section, a fan and a secondary filter rod section. The fan changes the direction of the airflow during suction and disperses the concentrated smoke to the surroundings, resulting in a more d...
