Remotely deployable vapor delivery device

摘要

A remotely deployable vapor delivery device is described that is conveniently and effectively deployed in a hard-to-reach location. The device is approximately spherical in shape, and includes an integrated reservoir containing the desired vapor producing substance, an evaporative surface and means for continuous flow of the vapor producing substance from the integrated reservoir to the evaporative surface which provides an approximately constant vapor delivery rate. The advantages of the embodiments include a device that can be conveniently tossed or rolled, is compact in size, provides a maximal amount of stored vapor producing substance, has an efficient usage rate of the stored vapor producing substance and provides a long operating lifetime. Other advantages of the embodiments described include hands-free activation, self-righting after deployment, tamper resistance, non-energized operation, a modest number of low cost parts that are readily manufactured and assembled, and easy retrieval.

主权项

1. A remotely deployable vapor delivery device comprising:
a generally spherical ball with an entirely unobstructed spherical outer surface; a reservoir positioned inside the spherical ball, the reservoir containing a vapor producing substance, and wherein the reservoir is permanently sealed except for a thru-hole containing an evaporative surface; the evaporative surface positioned inside the ball so that the evaporative surface is in a hollow portion in the ball, the evaporative surface also extending, in part, into the reservoir and in contact with the vapor producing substance; wherein the spherical ball further comprises a vent hole between the hollow portion through to the outside of the sphere; wherein substantially half of the inside of the spherical ball comprises the hollow portion having vent holes therein, and the other half of the spherical ball comprises the reservoir; and wherein the device has a center-of-mass in the portion of the spherical ball that comprises the reservoir.
