Detailed Description of the Invention
The handheld vacuum cleaner (1) of the present invention comprises a body having a removable outer casing (21) and a motor, a grip portion (3), a dust suction tube (4) and at least one battery (5).
In an embodiment of the present invention, the handheld vacuum cleaner (1) comprises a body (2) with a longitudinal (Y-Y) axis; the grip portion (3) which has a longitudinal (X-X) axis, which is positioned at the lower part of the body (2) and which is positioned to be connected to body (2) from at least a part of a connection portion (3.1), wherein the longitudinal X-X axis of the grip portion (3) extends transversely to the longitudinal Y-Y axis of the body (2); the dust suction tube (4) which has a longitudinal (Y-Y) axis and which is positioned at the bottom of the body (2) so as to be connected with the outer wall (21) through a first opening (4.1); and at least one battery (5) which positioned between the dust suction tube (4) and the grip portion (3).
In an embodiment of the present invention, the body (2) has a first separation portion and a second separation portion. The first separation portion has an outer casing (21) wherein the dust sucked by the dust suction tube (4) is collected to be then discharged, and the second separation portion has at least one motor (not shown in the figures) which is positioned at the second end (27) portion of the body (2) and which provides the necessary power for the handheld vacuum cleaner (1) to suck the dust, and a filter (not shown in the figures) which is positioned between the first separation portion and the second separation portion so as to prevent the dust collected in the first portion from entering the motor.
In an embodiment of the present invention, the first separation portion of the body (2) comprises an outer casing (21) which has walls defining a dust chamber (22); an inner casing (23) which defines a fine dust collection chamber disposed in the dust chamber (22); and a plurality of multiple cyclones (29) which are positioned adjacent to the inner casing (23) and which enable the separation of small particles in the dust chamber (22). Said small particles are retained by the filter positioned between the first separation portion and the second separation portion.
In an embodiment of the present invention, the body (2) comprises a removable outer casing (21) which has walls defining the dust chamber (22); a dust inlet opening (28) which is positioned on the first surface (24) of the outer casing (21) and which enables the foreign materials sucked by the dust suction tube (4) to be transferred to the dust chamber (22); an inner casing (23) which defines a fine dust collection chamber disposed in the dust chamber (22); a discharge section (30) which is positioned on the second surface (25) of the outer casing (21) and through which the dust in the dust chamber (22) is discharged; an air duct (31) which is positioned on the side of the discharge section (30) facing the dust chamber (22) so as to cover at least a portion of the discharge section (30) and which extends towards a first end (26) portion of the outer casing (21); and an air suction opening (31.1) which is provided between the air duct (31) and the first end (26). Thus, the dust in the dust chamber (22) is removed from the base surface at the first end (26) and vacuumed and an effective cleaning is carried out. As shown in Figure 2, the guiding air duct (31) which is positioned behind the dust discharge section (30) in the dust chamber (22) enables the vacuum to be made from the dust chamber (22) base. Moreover, by means of said air duct (31), the air entering the dust chamber (22) through a dust inlet opening (28) which is positioned on the first surface (24) of the outer casing (21) and which enables the foreign materials sucked by the dust suction tube (4) to be transferred to the dust chamber (22) rotates in the dust chamber (22) and enables particles stuck therein such as wool, fluff, large or fine dust to be swept and directed towards the air duct (31). Thus, even the finest dust particles at any point on the bottom of the dust chamber (22) are removed and cleaned by vacuuming.
In another embodiment of the present invention, the body (2) comprises an air duct (31) which is positioned on the side of the discharge section (30) facing the dust chamber (22) so as to cover the entire discharge section (30) and which extends towards a first end (26) portion of the outer casing (21).
In another embodiment of the present invention, the body (2) comprises an air duct (31) which is positioned on the side of the discharge section (30) facing the dust chamber (22) so as to cover at least a portion of the discharge section (30) and which extends so as to contact the base surface of the first end (26), and an air suction gap (31.1) which is provided on at least one side of the air duct (31) which is in contact with the first end (26).
In an embodiment of the present invention, the air duct (31) is positioned in the dust chamber (22) between the inner surface (21.1) of the outer casing (21) and the inner casing (23).
In an embodiment of the present invention, the air duct (31) is positioned in the dust chamber (22) between the inner surface (21.1) of the outer casing (21) and the inner casing (23) and the multiple cyclones (29). In an embodiment of the present invention, the body (2) comprises a discharge section
(30) which is positioned on the second surface (25) of the outer casing (21) and through which the dust in a dust chamber (22) is discharged; an air duct (31) which is positioned on the side of the discharge section (30) facing the dust chamber (22) and on the second surface (25) so as to cover at least a portion of the discharge section (30) and which extends parallel to the discharge section (30) so as to be aligned with the base surface of a first end (26) of the outer casing (21); and an air suction gap (31.1 ) which is provided at at least one side of the air duct (31) on the side of the first end (26).
In all embodiments of the present invention, the discharge section (30) and the air duct
(31) configuration is designed to provide efficiency sweeping of all the foreign materials and dust in the dust chamber (22) during the cleaning process. The air duct (31) is formed so as not to contact or so as to contact the base surface of the dust chamber (22), and if in contact, such that an air suction gap (31) is left. Here, the location of the air suction gap (31.1) can be determined according to the direction of the air flow inside the dust chamber (22) so as to be positioned on the right or left side of the air duct (31). Thus, it is provided that the air moving by rotating in the dust chamber (22) continues its rotation movement up to the base surface of the dust chamber (22) and the dust sweeping movement can be improved with the air on the base. Consequently, an air flow is created in the dust chamber (22) and all of the dust and foreign materials in the dust chamber (22) are discharged by means of said air flow.

In an embodiment of the present invention, the handheld vacuum cleaner (1) comprises a discharge section (30) wherein the lid (33) automatically shifts from the closed position to the open position upon being placed on the seating surface (9) at the dust collection station (7).
In an embodiment of the present invention, after the handheld vacuum cleaner (1) is placed on the dust collection station (7), the lid (33) provided on the second surface (25) of the outer casing (21) is seated on the vacuum port (8.1). The lid (33) seated on the vacuum port (8.1) opens automatically. After the lid (33) is opened, the air in the dust chamber (22) is directed by the effect of the vacuum and the foreign materials are swept into the opening (32), by means of the air duct (31) which is positioned on the side of the discharge section (30) facing the dust chamber (22) so as to cover at least a part of the discharge section (30) and which extends towards a first end (26) portion of the outer casing (21). Foreign materials passing through the vacuum channel (8) are transferred from the discharge port (8.2) to the collection portion (10). The lid (33) closes automatically when the handheld vacuum cleaner (1) is removed from the dust collection station (7) after the emptying of the dust chamber (22) is completed.
The cleaning process of the dust chamber (22) starts automatically when the handheld vacuum cleaner (1) is placed on the seating surface (9) of the dust collection station (7) or by pressing a button on the dust collection station (7). The dust collection station (7) is a structure having the vacuum channel (8), the collection portion (10 with a dust bag connected to the vacuum channel (8), a motor providing the operation of the dust collection station (7), and the air outlet filter provided between the motor and the collection portion (10). When the handheld vacuum cleaner (1) is seated on the dust collection station (7), the vacuum port (8.1) at the end of the vacuum channel (8) fits around the opening (32) provided on the second surface (25) of the dust chamber (22). The motor in the dust collection station (7) is operated and the dust in the dust chamber (22) starts to be sucked through the vacuum channel (8). Dust passes through the vacuum channel (8) and fills into the dust bag. On the other hand, the air passes through the dust bag to the motor and then passes through the filter provided after the motor so as to be discharged out. After the process is completed, the motor stops and the handheld vacuum cleaner (1) continues to be charged in the dust collection station (7).
