A load and sterilization combination control circuit arranged on a suction device includes a main control unit, a battery management unit, a load output unit, a load detection circuit and an ultraviolet sterilization circuit including an operation switch and an enabled switch connected with the operation switch in series and the main control unit. The load detection unit and the enabled switch are conducted to externally output. When a load of the suction device applied on the load output unit is detected by the main control unit via the load, detection circuit, the operation switch is configured to perform on-off control on the entire ultraviolet sterilization circuit after the enabled switch is turned on. The present disclosure can avoid waste electricity due to misoperation by performing a linkage control thereof and the ultraviolet sterilization circuit can work normally only after by connecting with the load and closing the operation switch.

An apparatus arranged to heat smokable material to volatilize at least one component of the smokable material has a housing. The housing has a first opening at a first end through which smokable material can pass so as to be received within and removed from the apparatus in use. The housing has a second opening at a second end opposed from the first end. The housing further has a chamber between the first and second openings. At least one heater is arranged within the housing for heating smokable material removably received within the chamber in use. A user can access the chamber through at least the second opening to clean within the apparatus

Disclosed is a mouthpiece assembly, including a lower mouthpiece cover and an upper mouthpiece cover. The lower mouthpiece cover is provided with a first air inlet passage and a first air outlet passage. The upper mouthpiece cover is provided with an air exiting hole. The upper mouthpiece cover can move relative to the lower mouthpiece cover. When the upper mouthpiece cover is in a first connection state relative to the lower mouthpiece cover, the first air inlet passage is in communication with the outside, and the first air outlet passage is in communication with the air exiting hole; and when the upper mouthpiece cover is in a second connection state relative to the lower mouthpiece cover, the first air inlet passage and the first air outlet passage are closed by the upper mouthpiece cover.

The invention relates to an aerosol-generating device comprising a mainbody (10) and a mouthpiece (12). The main body comprises a heating chamber (14) for receiving an aerosol-forming substrate. The mouthpiece is movably connected to the main body. The mouthpiece is configured movable with respect to the main body in a first movement between a first position and a second position. The first position is an operation position of the aero sol-generating device. In the second position, the heating chamber is at least partially exposed. The mouthpiece is configured movable with respect to the main body in a second movement between the second position and a third position. The second movement of the mouthpiece from the second position to the third position is configured to trigger an event.

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

A vape cleaning device for easily and thoroughly cleaning vape coils for reuse and avoiding the need for frequent replacement. The device has a base enclosing a fan oriented to direct air upwardly, a heat block suspended above the fan, a heating element coupled to the heat block, and a shield coupled to the base and having a central opening. A cup is removably positioned in the central opening of the shield and in contact with the heat block to be heated thereby. A vape coil holder may removably suspended in the cup that the vape coil is submerged in a cleaning fluid in the cup. After the cup has been warmed to a predetermined temperature for a cleaning cycle, the cup may be removed and the vape coil holder suspended from the shield. The fan may then be operated for a predetermined time period for a drying cycle.
