FIELD OF INVENTION
[001] The present invention relates to a device and a method using suction type
compressed air based sprayer gun for sanitization. More particularity the present
invention relates to a device to ensure safe work condition in industrial areas during
pandemic time.
BACKGROUND OF THE INVENTION
[002] To reduce growing pandemic of Covid 19, mass sanitization in the factory and
office areas has become mandatory. For example in heavy industry/ factory, which has
vast area, many buildings and works shops. As per Government recommendations, it
is required to sanitize working area daily i.e two times (before start & after completion
of shift) for both shift at all area.
[003] Hence for mass sanitization fire Engine and bhelmister are used commonly.
However the availability of fire engine and bhelmister is very limited. Due to covid 19
situation, fire engine driver and firemen demand has increased drastically. Due to
limited availability, sanitizing the complete work shop by using fire engine and
bhelmister consumes more time.
[004] Due to increase in waiting time, machine ideal time also increased and in turn
the regular productivity is affected and creates a demand in assemble area. Further by
using fire engine and bhelmister, narrow passages, corner places and other non-
approachable areas are difficult to sanitize periodically. It makes more difficulties and
worries to ensure safe health condition of the employees from growing pandemic of
Covid 19.

PRIOR ART OF THE INVENTION
[005] Existing prior art such as “US20110014093A1” discloses an apparatus for
sterilizing and disinfecting a target space by spraying a chemical including alcohol
includes a spray gun to which a chemical container containing a sterilizing and
disinfecting chemical including alcohol is attachable, a gas cylinder filled with a
compressed carrier gas that does not react with alcohol, and a pressure reducing valve
for decompressing the carrier gas discharged in a vaporized state from the gas cylinder
to a predetermined pressure, and is constructed so that the pressure reducing valve and
the spray gun are directly connected with a gas hose and mounted on a common truck.
The sterilizing and disinfecting apparatus can operate with a simple structure requiring
no power supply, and is much lighter in weight compared to conventional apparatuses.
[006] Another prior art such as “EP0421194A2”, discloses a Spray gun for a high-
pressure cleaning device with a housing which surrounds a liquid supply, an outlet line
and a closing valve and has a hand lever for opening the closing valve, characterized
in that the liquid supply line (2) is sealed in a sleeve (6) that the Outlet line (4) sealed
from the opposite side is inserted into the same sleeve (6) that one of the two lines (2,
4) forms a valve body (21) within the seal, to which a valve seat formed on the sleeve
(6) is formed (22) sealingly engages under the action of a spring (8) displacing the
sleeve (6) against the valve body (21), and that the closing lever (28) moves the sleeve
(6) against the force of the spring (8) when actuated.
[007] None of the above can fulfill the requirements for which the present has been
designed.
[008] It would therefore be advantageous to provide a device and a method using
suction type compressed air based sprayer gun for sanitization. Hence, the present

invention has been introduced which can serve the purpose efficiently for which it has
been designed.

[0052] Although embodiments for the present subject matter have been described in
language specific to package features, it is to be understood that the present subject
matter is not necessarily limited to the specific features described. Rather, the specific
features and methods are disclosed as embodiments for the present subject matter.
Numerous modifications and adaptations of the system/device of the present invention
will be apparent to those skilled in the art, and thus it is intended by the appended
claims to cover all such modifications and adaptations which fall within the scope of
the present subject matter.
[0053] It will be understood by those within the art that, in general, terms used herein,
and especially in the appended claims (e.g., bodies of the appended claims) are
generally intended as “open” terms (e.g., the term “including” should be interpreted as
“including but not limited to,” the term “having” should be interpreted as “having at
least,” the term “includes” should be interpreted as “includes but is not limited to,”
etc.). It will be further understood by those within the art that if a specific number of
an introduced claim recitation is intended, such an intent will be explicitly recited in
the claim, and in the absence of such recitation no such intent is present. For example,
as an aid to understanding, the following appended claims may contain usage of the
introductory phrases “at least one” and “one or more” to introduce claim recitations.
However, the use of such phrases should not be construed to imply that the

introduction of a claim recitation by the indefinite articles “a” or “an” limits any
particular claim containing such introduced claim recitation to inventions containing
only one such recitation, even when the same claim includes the introductory phrases
“one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a”
and/or “an” should typically be interpreted to mean “at least one” or “one or more”);
the same holds true for the use of definite articles used to introduce claim recitations.
In addition, even if a specific number of an introduced claim recitation is explicitly
recited, those skilled in the art will recognize that such recitation should typically be
interpreted to mean at least the recited number (e.g., the bare recitation of “two
recitations,” without other modifiers, typically means at least two recitations, or two
or more recitations). Furthermore, in those instances where a convention analogous to
“at least one of A, B, and C, etc.” is used, in general such a construction is intended in
the sense one having skill in the art would understand the convention (e.g., “a system
having at least one of A, B, and C” would include but not be limited to systems that
have A alone, B alone, C alone, A and B together, A and C together, B and C together,
and/or A, B, and C together, etc.). In those instances where a convention analogous to
“at least one of A, B, or C, etc.” is used, in general such a construction is intended in
the sense one having skill in the art would understand the convention (e.g., “a system
having at least one of A, B, or C” would include but not be limited to systems that
have A alone, B alone, C alone, A and B together, A and C together, B and C together,
and/or A, B, and C together, etc.). It will be further understood by those within the art
that virtually any disjunctive word and/or phrase presenting two or more alternative
terms, whether in the description, claims, or drawings, should be understood to
contemplate the possibilities of including one of the terms, either of the terms, or both
terms. For example, the phrase “A or B” will be understood to include the possibilities
of “A” or “B” or “A and B.”
[0054] It will be further appreciated that functions or structures of a plurality of
components or steps may be combined into a single component or step, or the

functions or structures of one-step or component may be split among plural steps or
components. The present invention contemplates all of these combinations. Unless
stated otherwise, dimensions and geometries of the various structures depicted herein
are not intended to be restrictive of the invention, and other dimensions or geometries
are possible. In addition, while a feature of the present invention may have been
described in the context of only one of the illustrated embodiments, such feature may
be combined with one or more other features of other embodiments, for any given
application. It will also be appreciated from the above that the fabrication of the unique
structures herein and the operation thereof also constitute methods in accordance with
the present invention. The present invention also encompasses intermediate and end
products resulting from the practice of the methods herein. The use of “comprising”
or “including” also contemplates embodiments that “consist essentially of” or “consist
of” the recited feature.
[0055] Although embodiments for the present subject matter have been described in
language specific to structural features, it is to be understood that the present subject
matter is not necessarily limited to the specific features described. Rather, the specific
features and methods are disclosed as embodiments for the present subject matter.
Numerous modifications and adaptations of the system/component of the present
invention will be apparent to those skilled in the art, and thus it is intended by the
