## Abstract

A cleaning kit for an aerosol generating device includes a power supplier; a cleaner configured to clean the aerosol generating device by moving while contacting at least one of an accommodation unit and a heater of the aerosol generating device, and a driver configured to operate the cleaner according to power from the power supplier, and including a gear unit for changing an operating torque of the cleaner.

## Claims

### Claim 1

A cleaning kit for an aerosol generating device, comprising:
a power supplier;
a cleaner configured to clean the aerosol generating device by moving while contacting at least one of an accommodation unit and a heater of the aerosol generating device;
a driver configured to operate the cleaner according to power from the power supplier, and including a gear unit for changing an operating torque of the cleaner; and
a controller configured to change the operating torque of the cleaner by controlling at least one of the power supplier and the driver,
wherein the gear unit comprises a first gear box and a second gear box, and
wherein the first gear box and the second gear box are configured to be controlled independently of each other by the controller.

### Claim 2 (depends on 1)

The cleaning kit for an aerosol generating device of claim 1,
wherein the power supplier is a battery, and
wherein the cleaning kit further comprises an interface for charging the battery.

### Claim 3 (depends on 1)

The cleaning kit for an aerosol generating device of claim 1, wherein the power supplier supplies power through a wired connection with an external device.

### Claim 4 (depends on 1)

The cleaning kit for an aerosol generating device of claim 1, further comprising a cover portion that covers the cleaner.

### Claim 5 (depends on 1)

The cleaning kit for an aerosol generating device of claim 1, further comprising a switch electrically connected to the controller, wherein the controller is configured to change the operating torque of the cleaner based on an operation of the switch.

### Claim 6 (depends on 1)

The cleaning kit of claim 1, wherein the controller is configured to:
cause the cleaner to move with a first operating torque by controlling the first gear box and the second gear box to operate;
cause the cleaner to move with a second operating torque by controlling the first gear box to operate without the second gear box operating; and
cause the cleaner to move with a third operating torque by controlling the second gear box to operate without the first gear box operating,
wherein the first operating torque, the second operating torque, and the third operating torque are different from each other.

### Claim 7 (depends on 1)

The cleaning kit for an aerosol generating device of claim 1, wherein the cleaner is detachably coupled to the driver, and comprises a cavity into which the heater is inserted when the cleaner is inserted into the accommodation unit of the aerosol generating device.

### Claim 8 (depends on 7)

The cleaning kit for an aerosol generating device of claim 7, wherein the cleaner comprises a brush arranged to surround at least a part of the cavity.

### Claim 9 (depends on 7)

The cleaning kit for an aerosol generating device of claim 7,
wherein the cleaner comprises a protrusion, and
wherein the driver comprises a groove for accommodating the protrusion.

### Claim 10 (depends on 7)

The cleaning kit for an aerosol generating device of claim 7, further comprising a coupling structure configured to couple the cleaner with the driver.

### Claim 11 (depends on 10)

The cleaning kit for an aerosol generating device of claim 10, wherein the coupling structure is configured to couple the cleaner with the driver by magnetic force.
