Abstract: A heating wire of an electronic atomizing device includes a central end, a distal end, and a plurality of spiral heating coils extending between the central end and the distal end. The plurality of spiral heating coils is coplanar and surrounds the central end. A mounting gap is formed between any two adjacent spiral heating coils in an extending direction of a reference line connecting the center end and the distal end. The widths of the mounting gaps gradually decrease along the extending direction of the reference line away from the central end. An electronic atomizing device including the aforementioned heating wire is further provided.

Abstract: A heating element for vaporization includes: a surface provided with a microgroove portion, the microgroove portion being arranged at least on one side of the heating element that is away from a preset liquid absorbing element, the microgroove portion having a microgroove, an opening of the microgroove being connected with the preset liquid absorbing element. The heating element is connectable with the preset liquid absorbing element to heat and vaporize to-be-vaporized liquid.

Abstract: An aerosol-forming article includes: an aerosol-forming substrate; an encapsulation layer encircling a recessed portion, the aerosol-forming substrate being arranged in the recessed portion; and a cover layer covering at least a part of the encapsulation layer and an opening of the recessed portion. The aerosol-forming substrate is arranged between the encapsulation layer and the cover layer. A through hole is provided at a position of the cover layer corresponding to the opening.

Abstract: A vaporization main unit includes: a mounting base comprising a mounting portion for mounting an aerosol-forming article; and a heating element for heating the aerosol-forming article, the heating element being arranged in the mounting portion. The mounting portion forms a groove. A bump is provided on a bottom surface of the groove, the heating element being arranged on the bump, the bump being in contact with the heating element. The heating element and a side surface of the groove are at least partially spaced.

Abstract: The present invention provides an irrigation system that allows user to input two soil moisture levels, i.e., the Dry Value and the Wet Value, by conducting a manual watering cycle, i.e., turning on the valves through a Controller when the soil needs watering and turning off the valves when the soil is sufficiently wet. The Controller keeps the soil moisture between the Dry and Wet Values by automatically turning on the valves when the soil moisture reaches the Dry Value, and turning off the valves when soil moisture reaches the Wet Value, at the user-determined desirable watering time periods of the day. In larger areas, the ground could be divided into multiple zones. The Controller could apply different Dry and Wet Values to different zones. The system's simplicity is further enhanced by the solar powered wireless moisture sensors.
