Hand-held power tool comprising a filter support
A hand-held power tool includes a housing, a filter support, a plurality of securing element, and an actuating unit. The filter support has receiving openings, at least one first fixing element, and at least one second fixing element. The receiving openings are configured to receive filter elements configured to seal the hand-held power tool against a penetration of dust into the housing of the hand-held power tool. First and second fixing elements are fixable to corresponding securing elements arranged on the hand-held power tool, and are configured to releasably fix the filter support to the housing. The actuation unit is actuatable to release the filter support from the hand-held power tool.
1. A hand-held power tool, comprising:
a housing defining a longitudinal axis and including an outer curved surface extending along the longitudinal axis and a rear surface extending from the outer curved surface and intersecting the longitudinal axis;
at least one first securing element formed in the outer curved surface of the housing;
at least one second securing element formed in the rear surface of the housing; and
a filter carrier including:
at least one filter carrier element having at least one first receiving opening configured to receive a first filter element;
at least one first fastening element extending from a first interior surface of the filter carrier and configured to separably fasten to the at least one first securing element via positive engagement to mount the filter carrier on the housing; and
at least one second fastening element extending from a second interior surface of the filter carrier and configured to separably fasten to the at least one second securing element via non-positive engagement to mount the filter carrier on the housing; and
an actuating unit including a structured surface region formed on an outer surface of the filter carrier opposite the first interior surface,
wherein the at least one first fastening element is located between the structured surface region and the rear surface of the housing along the longitudinal axis when the filter carrier is mounted on the housing,
wherein the first filter element covers at least one air opening formed in the outer curved surface of the housing when the filter carrier is mounted on the housing, and
wherein the filter carrier is configured such that in response to a radial force effected upon the structured surface region toward the longitudinal axis, the at least one first fastening element is separated from the at least one first securing element to enable removal of the filter carrier from the housing.
2. The hand-held power tool as claimed in claim 1 , wherein the at least one first fastening element and the at least one second fastening element are positioned at opposite end regions of the filter carrier.
3. The hand-held power tool as claimed in claim 1 , wherein when the filter carrier is mounted on the housing the filter carrier is arranged substantially along the longitudinal axis with the first interior surface positioned against the outer curved surface and with the second interior surface positioned against the rear surface.
4. The hand-held power tool as claimed in claim 1 , wherein the at least one first fastening element is a latching element.
5. The hand-held power tool as claimed in claim 1 , wherein the at least one first fastening element is integral with the actuating unit.
6. The hand-held power tool as claimed in claim 1 , wherein the filter carrier is substantially U-shaped.
7. The hand-held power tool as claimed in claim 1 , wherein the at least one second securing element is an air inlet opening of the hand-held power tool.
8. The hand-held power tool as claimed in claim 1 , wherein the outer surface of the filter carrier is configured such that, when the filter carrier is mounted on the housing, the outer surface is flush with an outer surface of the housing extending from the outer curved surface.
9. The hand-held power tool as claimed in claim 1 , wherein:
the at least one filter carrier element includes at least one second receiving opening configured to receive a second filter element, and
the second filter element covers at least one air opening formed in the rear surface of the housing when the filter carrier is mounted on the housing.
10. The hand-held power tool as claimed in claim 1 , wherein:
the at least one first fastening element extends toward the longitudinal axis when the filter carrier is mounted on the housing, and
the at least one second fastening element extends parallel to the longitudinal axis when the filter carrier is mounted on the housing.
11. The hand-held power tool as claimed in claim 1 , wherein:
the radial force effected upon the structured surface region moves a distal end of the at least one first fastening element toward the rear surface of the housing to separate the at least one first fastening element from the at least one first securing element and to enable the removal of the filter carrier from the housing.
