The smart electric incense and perfume burner is a remotely controllable, electrical incense burner controllable via a smart system using Wi-Fi or Bluetooth. The burner is in the form of an orb or spherical shell, which may be placed on top of a pedestal having a battery charging circuit. The orb functions separately as a portable, battery-operated, smart electric incense and perfume burner. The orb includes an upper chamber, centrally located at the top of the orb for liquid incense or perfume. The orb also includes a lower chamber with a solid incense heater. The outer surface of the orb has a plurality of vent openings for allowing smoke from the upper and lower chambers to exit the interior of the orb. The vent openings are surrounded by multicolor LEDs and are adapted to receive elongated decorations for display.

A gas humidifier can have a gas channel comprising an inlet and an outlet. A portion of the gas channel can have a region having a reduction in cross-sectional area relative to the portions of the gas channel outside of the region. A water conduit can extend from the region to a water reservoir. A heating element can heat water entering the region from the water conduit. Water vaporized using the heating element can join the flow of gases passing through the gas channel in use.

The present invention relates to a mixer device for distributing and evaporating a liquid introduced into a gas flow, in particular into an exhaust-gas flow, wherein the mixer device comprises at least one mixer vane (14a) which influences the flow direction of the gas flow. The mixer vane has a first vane (14a′) portion and a second vane portion (14a″) which are arranged in series in the flow direction of the gas flow, which vane portions are designed so that the first vane portion diverts the gas flow approaching the mixer device such that said gas flow has a first swirl component imparted thereto, and so that the second vane portion subsequently diverts the gas flow such that said gas flow has a second swirl component imparted thereto, wherein the first swirl component and the second swirl component oppose one another.

The present disclosure includes mixing apparatuses comprising a pipe having an internal channel having a convergent frustoconical portion, and a divergent portion. The divergent portion may comprise a divergent frustoconical portion and an annular, concave curved portion. A plurality of injection ports may be spaced circumferentially in the convergent frustoconical portion and communicate a liquid into internal channel. The plurality of injection ports may define an opening in the internal channel having a first dimension in a circumferential direction that is larger than a second dimension in a longitudinal direction. The injection mixer may be configured to mix a first fluid flowing through the pipe with the second fluid to form a fully homogenous, dispersed fluid mixture.
