 a thermal insulation chamber between layers of a multi-layer sidewall. 
 
   
     
     
         2 . The accessory of  claim 1 , wherein the thermal insulation chamber shrinks until it vanishes along a direction of an airflow, and the multi-layer sidewall merge into a single-layer sidewall at the air outlet. 
     
     
         3 . The accessory of  claim 1 , wherein along a direction of an airflow, the size of the guide chamber increases along a first direction and decreases along a second direction;
 the first direction is perpendicular to the second direction;   the multi-layer sidewall are configured in at least part of the airflow portion along the first direction and the single-layer sidewall is configured along the second direction.   
     
     
         4 . The accessory of  claim 3 , wherein the air inlet is circular and its dimensions are the same along the first direction and the second direction,
 the air outlet is flat, and its size is larger than the air inlet along the first direction, and smaller than the air inlet along the second direction.   
     
     
         5 . The accessory of  claim 3 , wherein along the direction of the airflow, the thermal insulation chamber gradually shrinks in size along the second direction until it vanishes. 
     
     
         6 . The accessory of  claim 3 , wherein an outer sidewall of the airflow portion is configured with a concave-convex structure along the second direction. 
     
     
         7 . The accessory of  claim 6 , wherein the outer sidewall of the airflow portion and/or the concave-convex structure are configured with one or more vents in connection to the thermal insulation chamber. 
     
     
         8 . The accessory of  claim 3 , wherein, along the direction of the airflow, an outer sidewall of the airflow portion shrinks or remains unchanged along the first direction and shrinks along the second direction. 
     
     
         9 . The accessory of  claim 3 , wherein the single layer sidewall is configured with one or more vents at the air outlet. 
     
     
         10 . The accessory of  claim 9 , wherein the vent is configured along the first direction and/or on the single layer sidewall along the second direction. 
     
     
         11 . The accessory of  claim 1 , wherein the mounting portion is annular, the airflow portion is configured inside the annular mounting portion, and a part of the airflow portion extends radially and is coupled to the mounting portion. 
     
     
         12 . The accessory of  claim 1 , wherein the airflow portion comprises an outer sidewall and an inner sidewall at a part adjacent to the air inlet;
 wherein the air inlet is configured inside the inner sidewall, and the outer sidewall extends radially and is coupled to the mounting portion.   
     
     
         13 . The accessory of  claim 12 , wherein a cover is configured in the airflow portion and seal the thermal insulation chamber;
 wherein an outer end face of the cover forms partially an outer end face of the accessory.   
     
     
         14 . The accessory of  claim 13 , wherein the mounting portion is configured between the outer sidewall and the inner sidewall, and the cover is coupled to the mounting portion through a mount. 
     
     
         15 . The accessory of  claim 1 , wherein the mounting portion and the airflow portion are integrally formed. 
     
     
         16 . A drying assembly, comprising:
 a drying apparatus; and   the accessory as described in any of  claim 1 .   
     
     
         17 . The drying assembly of  claim 16 , wherein an end of the drying apparatus is configured with an air outlet element for emitting an airflow and a radiation element for emitting infrared radiation;
 wherein the accessory is configured to be detachably attached to the drying apparatus, the air inlet corresponds to the air outlet element, and the accessory comprises a hollow portion corresponding to the radiation element.   
     
     
         18 . The drying assembly of  claim 17 , wherein on the accessory, the hollow portion is configured between the airflow portion and the mounting portion, and the outer sidewall of the airflow portion spans the hollow portion to be coupled to the mounting portion. 
     
     
         19 . The drying assembly of  claim 17 , wherein the accessory further comprises a cover made of a heat-resistant material and/or a reflective material, and the cover covers an area on the airflow portion and the mounting portion facing the radiation element.
