Filter, aerosol generating article, and aerosol generating device

Abstract

An aerosol generating device includes a filter and an aerosol generating article. The filter is configured to cooperate with an atomizer unit and the aerosol generating article. The filter includes an inhalation channel, a main unit connection portion, and an article connection portion. The filter is detachably connected to the atomizer unit through the main unit connection portion. The aerosol generating article is detachably connected to an air inlet of the inhalation channel through the article connection portion.

         2 . The filter of  claim 1 , wherein the article connection portion is an insertion slot. 
     
     
         3 . The filter of  claim 2 , further comprising a separator between the inhalation channel and the insertion slot. 
     
     
         4 . The filter of  claim 3 , wherein a first positioning portion of the separator is a positioning post cooperating with a positioning hole on the aerosol generating article. 
     
     
         5 . The filter of  claim 1 , wherein the filter has a first air inlet channel for guiding external air toward the aerosol generating article; and
 a side wall of the inhalation channel is provided with a second air inlet channel in communication with an outside environment.   
     
     
         6 . The filter of  claim 2 , further comprising:
 a connection section being inserted into a housing of the atomizer unit, and   the main unit connection portion is arranged on an outer side wall of the connection section.   
     
     
         7 . The filter of  claim 6 , further comprising:
 a first air inlet channel that guiding external air toward the aerosol generating article, the first air inlet channel including a first sub-channel being arranged on a side wall of the main body section, to guide the external air toward an outer surface of a side wall of the connection section, and a second sub-channel extending through the side wall of the connection section and communicating with the insertion slot.   
     
     
         8 . The filter of  claim 1 , wherein the filter is a snap-fitted or threadedly connected to the atomizer unit housing. 
     
     
         9 . An aerosol generating article, configured for use in cooperation with the filter of  claim 1 , wherein the aerosol generating article comprises at least one aerosol generating substrate. 
     
     
         10 . The aerosol generating article of  claim 9 , wherein an end of the aerosol generating substrate is inserted into the filter. 
     
     
         11 . The aerosol generating article of  claim 10 , wherein the aerosol generating substrate has a first positioning portion and a second positioning portion. 
     
     
         12 . The aerosol generating article of  claim 11 , wherein the second positioning portion is a positioning hole cooperating with a positioning post on the filter. 
     
     
         13 . The aerosol generating article of  claim 10 , wherein the aerosol generating substrate is an integrated structure. 
     
     
         14 . The aerosol generating article of  claim 10 , wherein the aerosol generating substrate has an airway. 
     
     
         15 . The aerosol generating article of  claim 14 , wherein the airway is connected at least an end of the aerosol generating substrate, or wherein the airway is connected at least one of an interior of the aerosol generating substrate and an outer side wall of the aerosol generating substrate. 
     
     
         16 . The aerosol generating article of  claim 14 , wherein the airway is a pass-through airway, or the airway is a spiral airway, wherein at least part of a region of the spiral airway is in a curved shape. 
     
     
         17 . An aerosol generating device, comprising:
 a filter including an inhalation channel, a main unit connection portion, and an article connection portion;   an atomizer unit including a housing and a heating component arranged in the housing; and   the filter being detachably connected to the housing through the main unit connection portion.   
     
     
         18 . The aerosol generating device of  claim 17 , further comprising:
 the housing being provided with a heating cavity, the filter further comprising a first air inlet channel which including a first sub-channel and a second sub-channel, a gap being formed between the filter and an inner side wall of the housing, and the second sub-channel and the inhalation channel are in communication with the heating cavity.   
     
     
         19 . The aerosol generating device of  claim 18 , the filter further comprising a second air inlet channel, and the second air inlet channel extends through the side wall of a main body section of the filter and communicating with the inhalation channel. 
     
     
         20 . The aerosol generating device of  claim 18 , wherein the filter is connected to the housing through the main unit connection portion, and a side wall of the inhalation channel is provided with a second air inlet channel in communication with an outside environment.
