Description

[0001] CYCLONIC PORTABLE VACUUM CLEANER [0002]

The present invention relates generally to a cyclone portable vacuum cleaner.

Cyclone portable vacuum cleaners including a main body and a cyclone chamber, as disclosed in patent document EP2043493B1, are known in the prior art. Instead, the system is particularly at risk of scratching the base of the transparent cyclone chamber, especially when the user places the vacuum cleaner on a support (floor, table or shelf). In addition, the base of the cyclone chamber of the device can form a lid, and each time the user places the vacuum cleaner on the support, an external force is applied to the sealed joint or seal, . ≪ / RTI >

It is an object of the present invention to overcome the disadvantages of the above-mentioned prior art and to provide a durable product which maintains a good state over time and maintains its integrity even when the device is regularly handled, A cyclone portable vacuum cleaner having a cyclone chamber is proposed.

For that purpose, a first aspect of the present invention is a method for producing

- Main body,

An aeration circuit comprising an inlet and an outlet, and

- a cyclone chamber interlocked with the main body and arranged to separate contaminants from the air stream passing through the vent circuit,

The main body and the cyclone chamber each have a base,

Wherein the base of the main body includes a main lower surface and support means defining a support plane of the vacuum cleaner for placing the vacuum cleaner on a flat support,

Wherein the base of the cyclone chamber is offset from the support plane so that only the support means of the main body base rest on a flat support.

According to the above-described embodiment, the base of the cyclone chamber is offset upwardly with respect to the support plane, thereby ensuring that the base of the cyclone chamber does not contact the support on which the cyclone portable vacuum cleaner rests. This results in no friction between the cyclone chamber base and the support, or friction between the contaminants on the support or on the cyclone chamber base. Thus reducing the risk of scratching the cyclone chamber. In other words, the cyclone chamber base has a lower surface, the lower surface of which is spaced a predetermined distance from the support plane to prevent contact between the cyclone chamber base and the support on which the device rests.

Furthermore, when not equipped with accessories, the weight of only the main body containing the electrical energy storage means is sufficient to ensure stability on its support means of the cyclone portable vacuum cleaner.

Advantageously, the support means comprise two longitudinal side ribs disposed on each side of the main lower surface of the main body base. Such ribs are easy to manufacture, for example by molding. Further, since the side ribs are disposed on each side of the lower surface of the rectangular main body base portion, excellent stability is provided.

Advantageously, the two termination side ribs have an increasing slope in the direction of the cyclone chamber.

Advantageously, the support means comprise a transverse rib disposed between the two termination side ribs and disposed on the edge of the main lower surface of the main body base adjacent to the cyclone chamber. The implementation enables support by the nearest neighboring transverse ribs of the cyclone chamber, thereby improving the stability of the vacuum cleaner when it is placed on a support.

Advantageously, the vacuum cleaner has a center of gravity limited to the main body when it is not equipped with its accessories. In other words, when the device is placed on a horizontal support, the center of gravity viewed from above is positioned vertically inside the surface defined by the support means in contact with the support. This allows the device to automatically return to a stable position when it is out of balance. In particular, when the device is out of balance towards the front, the lower surface of the cyclone chamber is held in position as a braking device on the support before the device is stabilized (by itself by the leverage effect of the weight of the device) .

Advantageously, the base of the main body forms a shoulder at the interface with the cyclone chamber base.

Advantageously, the support means of the main body include grooves facing the flat support when the support means of the main body base are placed on a flat support. The grooves allow material to be saved during manufacture and to limit contact between the main lower surface of the main body and the support, thereby improving stability when the support is uneven or contaminated.

Advantageously, the cyclone chamber includes a body that is articulated on the body and the body and defines a cover that forms at least a portion of the cyclone chamber base. The displacement of the cyclone chamber base thereby limits the stress on the lid and its joint connection, since the appliance does not rest on its cover and its joint connection when the user places the appliance on the support.

Advantageously, the lid is articulated on the body by pivotal connection.

Advantageously, the base of the cyclone chamber has a flat lower surface that is substantially parallel to the support plane and located at a predetermined distance in the range of values from 3 mm to 15 mm from the support plane. This ensures that the base of the cyclone chamber is sufficiently spaced from the support when the device is placed on the support.

Advantageously, the base of the cyclone chamber has a lower surface that has a distance from the main body base and a supporting plane that progressively increases from the edge to the free end of the adjacent cyclone chamber base, the free end having a value from 4 mm to 15 mm Lt; RTI ID = 0.0 > a < / RTI > This ensures that the base of the cyclone chamber is sufficiently spaced from the support when the device is placed on the support.

Advantageously, the base of the cyclone chamber has a flat lower surface with an increasing slope from the interface with the main body base to the free end, said free end being located at a predetermined distance in the range of values from 4 mm to 15 mm from the support plane do. This ensures that the base of the cyclone chamber is sufficiently spaced from the support when the device is placed on the support.

Advantageously, the base of the cyclone chamber has a curved lower surface having a convex curve from the interface with the main body base to the free end, said free end being located at a predetermined distance in the range of values from 4 mm to 15 mm from the support plane . This ensures that the base of the cyclone chamber is sufficiently spaced from the support when the device is placed on the support.

Advantageously, the main body includes a housing for electrical energy storage means such as a battery, and the main lower surface of the main body base forms the lower wall of the housing for the electrical energy storage means. In other words, the electrical energy storage means is located in the lower part of the main body, thereby making it possible to stabilize the device better.

The configuration allows the center of gravity to be positioned very low on a cyclone portable vacuum cleaner, thereby further increasing stability.

Advantageously, at least a portion of the support means is formed of an elastomeric material such as EPDM (ethylene propylene-diene monomer). Such materials limit impacts and have a significant coefficient of friction, for example, to improve resistance to slippage on inclined supports.

Advantageously, the support means project against the main lower surface of the main body base.

Advantageously, the cyclone chamber is proximate to the main body.

Advantageously, the base of the cyclone chamber is formed of a transparent material. This makes it possible to easily adjust the filling level in the cyclone chamber so as to know when to empty the cyclone chamber. It is contemplated that the cyclone chamber may be implemented, for example, with polycarbonate.

Advantageously, the cyclone chamber is elongated along the main direction substantially perpendicular to the support plane.

Advantageously, the main body includes grip means such as a handle or the like.

Advantageously, the main body includes a control means, such as a trigger, arranged to operate by a user to control the cyclone portable vacuum cleaner.

Advantageously, the cyclonic portable vacuum cleaner includes a motorized ventilator, preferably disposed within the main body.

Advantageously, the vent circuit is disposed within the main body.

Advantageously, the cyclonic portable vacuum cleaner includes a detachable pipe and an inhaler arranged to engage the main body to form a stick-type vacuum cleaner.

Other features and advantages of the present invention will become more apparent by reading the detailed description which follows, purely by way of example and without limitation, illustrating the present invention.

Figure 1 shows a cyclone portable vacuum cleaner according to the present invention placed on a support.
2 is a detailed view of the cyclone portable vacuum cleaner of FIG.
FIG. 3 is a bottom view of the cyclone portable vacuum cleaner of FIG. 1;
Fig. 4 is another bottom view of the cyclone portable vacuum cleaner of Fig. 1; Fig.
Figure 5 is a side view of the cyclone portable vacuum cleaner of Figure 1 with accessories.
Figure 6 shows the cyclone portable vacuum cleaner of Figure 1 in an unstable position.

1 is a side view of a cyclone portable handheld device according to the present invention that rests on a support 100 (floor, table or shelf) and includes a main body 10, a cyclone chamber 30, an inlet 21, A vacuum cleaner is shown. As shown in FIG. 1, a brush can be provided at the position of the intake port 21 to rub the floor to be cleaned.

Typically, the cyclonic portable vacuum cleaner includes a ventilation circuit formed between the intake port 21 and the exhaust port 22, and a power fan designed to generate airflow in the ventilation circuit. The cyclone chamber (30) is located on the airflow trajectory and separates the contaminant sucked in through the air inlet by the power effect from the airflow.

Helical motion is applied to the airflow within the cyclone chamber 30, which allows the contaminants to be discharged to temporarily store and collect the contaminants within the lower portion of the cyclone chamber 30. [ Typically, the cyclone chamber 30 is formed of a transparent plastic material so that the user can easily ascertain the level of contaminants to periodically empty the cyclone chamber 30.

To this end, the cyclone chamber 30, which is mainly formed by the body 33, is located in the lower portion of the cyclone chamber 30 and is connected to the body 33 by a pivotal connection along the pivot axis 32, For example, on the trash can, so that the contaminants can be easily emptied from the trash can.

Of course, the present invention is by no means limited to the embodiment provided as an example. Thus, the cyclone chamber 30 may be very well emptied through the top after separating the cyclone chamber 30 from the rest of the cyclone portable vacuum cleaner.

The main body 10 therefore includes a power fan and the body also includes a handle 11 for providing excellent ergonomics in use, a control trigger 12 for function control, and an electrical energy storage means for power fan power supply- In this case, the battery 16 -.

As shown in FIG. 1, the cyclone portable vacuum cleaner is designed to be stably placed on the support 100. However, the cyclone chamber 30, and in particular its lid 31, is made of a transparent plastic material, and the lid 31 may be scratched due to friction on the support 100, which may be covered with contaminants, . In addition, the connection between the main body 33 and the lid 31 must be sealed and the lid 31 must be able to open without difficulty. Repeated shocks between the support 100 and the lid 31 may interfere with its sealing and / or opening function.

As a result, one of the aspects of the present invention is to provide a space between the cover 31 and the support 100. In other words, when the cyclone portable vacuum cleaner is placed on the flat support 100, the cyclone chamber 100 is moved so that friction prevention (for scratch prevention) and / or shock prevention (for maintaining the sealing and / or opening function of the lid 31) A predetermined distance d is provided between the lower surface of the support base 30 and the support base 100. [

In other words, the main body 10 includes support means on its base (lower surface), so that the support means form a support surface (consistent with the flat support 100 of Figure 1) The base 30 is offset relative to its support plane to avoid contact with the flat support 100.

Figure 2 shows in detail the deviation of the base of the cyclone chamber 30 relative to the support plane formed by the support means of the base of the main body 10 wherein the edge of the base of the main body 10 adjacent to the cyclone chamber 30 10a from the base of the cyclone chamber 30 increasing. Alternatively, the lower surface of the cyclone chamber 30 parallel to the support 100 or parallel to any plane can be considered. However, the base (or at least the lowest point thereof) of the cyclone chamber 30 may be located on the support plane formed by the support means so that it does not contact the support 100 when the cyclone portable vacuum cleaner is placed on the support 100 It is always wrong.

In order to ensure excellent stability, the battery 16 is disposed in a housing provided in the lower portion of the base of the main body 10. The housing wall of the battery 16 is formed by the main lower surface 19 of the main body 10. Thus, the center of gravity of the instrument (i.e., without accessories) of Figure 1 is located very low in the main body 10, which allows the instrument to be imbalanced at the position shown in Figure 6, 1 < / RTI > It should also be noted that in Figure 6 the lower edge of the cyclone chamber 30 opposite the main body 10 abuts against the support 100, Is sufficient to restore the device to a stable position.

Figure 3 is a bottom perspective view of the device of Figure 1 showing the support means of the base of the main body 10 and in particular the two side ribs 16a and 16b arranged in the longitudinal direction of the base of the main body 10, And grooves 18 formed in the main lower surface are shown.

At the location of the base of the main body 10 adjacent the cyclone chamber 30, the transverse ribs 17 form a shoulder with the cyclone chamber 30. The two side ribs 16a and 16b and the transverse ribs 17 project against the main lower surface 19 of the base of the main body 10 and are arranged in the production facility, typically in the extruder, . In order to ensure stability in the disclosed case, the two side ribs 16a, 16b have an increasing slope in the direction of the cyclone chamber 30.

In order to increase the stability on the support 100, it is conceivable to form the side ribs 16a and 16b from a soft elastic material such as EPDM (ethylene propylene-diene monomer). Such materials limit the impact, and by having a significant coefficient of friction, the resistance to slippage on the support, for example, which can be inclined, is improved.

On the base of the main body 10 of Fig. 3, a cap 13 for closing the housing for the battery 16 is also noted.

Figure 4 shows the increasing inclination of the two side ribs 16a and 16b and the transverse rib 17 and in particular the two side ribs 16a and 16b at different angles and between the transverse ribs 17 and the lid 31 The recesses 19 are shown at different angles to ensure that the lid is maintained at an appropriate distance from the support 100 and thus the position of the cyclone chamber 30) on the lower surface of the substrate.

5 shows a cyclone portable vacuum cleaner with optional accessories such as an inhaler 50 having an extension pipe associated with the inlet 21. Such an inhaler 50 advantageously makes it possible to form a stick-type vacuum cleaner.

It will be understood that various modifications and / or improvements, obvious to those of ordinary skill in the art, may be made to numerous embodiments of the invention disclosed herein without departing from the scope of the invention as defined by the appended claims.
