  • Publication number: 20260232045
    Abstract: An example adapter device includes a power-side connector configured to be coupled to a power source. A device-side connector can be configured to be coupled to a portable inhalation device. A power adapter can condition electricity received from the power source such that the electricity is usable by the portable inhalation device. For example, the portable inhalation device can use the conditioned electricity from the power adapter, rather than chemical-battery power, to vaporize a substance for inhalation. In another example, an example device is provided for powering a portable inhalation device without using a chemical-based battery, such as by utilizing a capacitor that stores energy received from the power source and dispenses the stored energy to the portable inhalation device to vaporize a material for inhalation.

  • Publication number: 20260182662
    Abstract: A user-configurable smoking device may include a body portion shaped to receive a cartridge and a filter, a mouthpiece coupled to the body portion, and a control mechanism. The control mechanism may selectively allow airflow through either the cartridge or filter, providing a cartridge-operation mode or a filter-operation mode. In the cartridge-operation mode, air flow may be allowed into the body portion and through the cartridge and mouthpiece. In the filter-operation mode, air flow may be allowed into the mouthpiece and through the filter and body portion. The control mechanism may be configured to enable a user to select between the cartridge mode or filter mode without inhaling or exhaling through the mouthpiece.

  • Publication number: 20260150912
    Abstract: A method and device for providing a multiple-sensation inhalation experience are described. The method involves machining a bamboo tube to create a hollow cavity with an inlet and outlet, soaking the tube in a flavor solution, and inserting a cotton insert soaked in a sensation solution. A second cotton insert can also be inserted to control and customize air flow through the device. The device comprises a machined bamboo tube infused with a flavor solution and a cotton insert infused with a sensation solution, allowing users to experience taste and sensation when inhaling through the device.

  • Publication number: 20260152315
    Abstract: Systems and methods are provided for filling liquid-capable vessels, such as cartridges or smoking devices, while retained in retail packaging. These examples include a fill-through packaging unit for fillable devices and an improved manufacturing process for use in smoking device production. The fill-through packaging unit can include a positioning component, an outer body portion, a puncturable cover, and a guide component. The unit can enable filling operations to occur after the fillable device has been placed in its final retail packaging, such as by providing aligned access from an external surface to an internal filling port. The packaging unit can automatically maintain spatial alignment between the outer filling location and the device filling location, can protect the device during filling operations, and can facilitate batch processing of multiple units simultaneously.
