Abstract
An agrichemical spray mask according to the present invention comprises: a main body (114) which is worn hermetically attached to the face and has an inhalation inlet port (110) and an exhalation outlet port (112); an anti-dust and anti-toxin filter tube (120) which is provided on the outside of the inhalation inlet port (110) of the main body (114) of the mask so as to link to the inhalation inlet port and is provided with an anti-dust and anti-toxin filter (113); and a spray filter tube which is separably fastened to the anti-dust and anti-toxin filter tube (120), has a spray filter (223) provided on the inside thereof, and has a respiration port (220a). In the present invention, because two-stage filtering is used to ensure that agrichemical sprays are not breathed in via the human respiratory organs and at the same time the filter is not much soaked by the agrichemicals, it follows that the time over which the mask is used can be extended and, if the filter does become soaked with agrichemicals, the filter can easily be replaced and cleaned.
