Cleaning assembly

Abstract

Cleaning assemblies for aerosol provision devices are disclosed. In one example a cleaning assembly comprises: a shaft defining a longitudinal axis; and a cleaning element disposed at an end of the shaft. The cleaning element comprises a proximal portion and a distal portion adjacent to the proximal portion. The proximal portion has a greater cross section in the direction perpendicular to the longitudinal axis of the shaft than the distal portion. In another example, an aerosol provision device cleaning assembly comprises: a shaft; a first cleaning element disposed at a first end of the shaft; and a second cleaning element disposed at a second end of the shaft. The first cleaning element is larger than the second cleaning element

1 . A cleaning assembly for an aerosol provision device, the cleaning assembly comprising:
 a shaft defining a longitudinal axis; and   a cleaning element disposed at an end of the shaft;   wherein:   the cleaning element comprises a proximal portion and a distal portion adjacent to the proximal portion; and   the proximal portion has a greater cross section in the direction perpendicular to the longitudinal axis of the shaft than the distal portion.   
     
     
         2 . The cleaning assembly according to  claim 1 , wherein the proximal portion and the distal portion are coaxially arranged. 
     
     
         3 . The A cleaning assembly according to  claim 2 , wherein the proximal portion, the distal portion and the shaft are coaxially arranged. 
     
     
         4 . The cleaning assembly according to  claim 1 , wherein the proximal portion and the distal portion are joined at an interface surface, the interface surface being on a plane that is perpendicular to the longitudinal axis. 
     
     
         5 . The cleaning assembly according to  claim 1 , wherein the length of the cleaning element is between 5 mm and 30 mm. 
     
     
         6 . The cleaning assembly according to  claim 1 , further comprising a second cleaning element disposed at an opposite end of the shaft to the cleaning element. 
     
     
         7 . The cleaning assembly according to  claim 1 , wherein at least one of the proximal portion, the distal portion and the second cleaning element is substantially cylindrical. 
     
     
         8 . The cleaning assembly according to  claim 7 , wherein the distal portion and the second cleaning element are both substantially cylindrical and have substantially equal diameters. 
     
     
         9 . The cleaning assembly according to  claim 6 , wherein the length of the second cleaning element is between 5 mm and 25 mm. 
     
     
         10 . The cleaning assembly according to  claim 1 , wherein the length of the proximal portion is between 2 and 10 times greater than the length of the distal portion. 
     
     
         11 . The cleaning assembly according to  claim 10 , wherein the length of the proximal portion is between 4 mm and 20 mm. 
     
     
         12 . The cleaning assembly according to  claim 10 , wherein the length of the distal portion is between 1 mm and 10 mm. 
     
     
         13 . An aerosol provision device cleaning assembly comprising:
 a shaft having a first end and a second end;   a first cleaning element disposed at the first end of the shaft; and   a second cleaning element disposed at the second end of the shaft;   wherein the first cleaning element is larger than the second cleaning element.   
     
     
         14 . The cleaning assembly according to  claim 13 , wherein the length of at least one of the first portion and the second portion is between 5 mm and 30 mm.
