Description
Technical Field
The present invention relates to a cleaning head for cleaning a surface, and more particularly to a cleaning head of a vacuum cleaner equipped with a suction head, which enables small-sized waste and dust present on a surface to be cleaned to be sucked.
Background
Suction cleaners equipped with a suction head are well known in the market, which make it possible to clean surfaces by suction in order to remove small-particle waste and dust on the surfaces. The surface to be pumped may be, for example, a tile, floor, laminate, carpet or carpet.
The suction head comprises, in a known manner, a main body comprising a sole plate provided with a lower surface and a suction aperture opening at the lower surface of the sole plate. During use of the suction head, the lower surface of the sole plate will be positioned in an adjacent manner to the surface to be sucked.
In order to increase the suction efficiency of the suction head, in particular to efficiently suck dust and waste on the carpet, it is known to equip the suction head with a cleaning element which is detachably mounted in a containing housing which is provided on the main body and which is open at the lower surface of the sole plate. One such cleaning element may, for example, comprise a rotating brush, which may be electric or non-electric. Such a rotating brush makes it possible in particular to turn up dust, threads or waste present on carpets, carpets or the like in order to suck them better.
The fact that the cleaning elements are detachably mounted in a receiving housing provided on the main body makes it possible for a user to clean or replace the rotating brush, for example.
In order to avoid undesired escape of the cleaning element from the housing during use of the suction head, it is known to equip the cleaning element with a locking member configured to cooperate with the body, for example a bayonet locking member or a locking member that requires the use of a specific tool to move it into the release position.
Thus, for some users, removing such cleaning elements from the containment housing may prove complicated.

Detailed Description
Figures 1 to 7 show a cleaning head 2, and more particularly a suction head, comprising a connecting sleeve 3 to which a joint of rigid or flexible tubing is to be connected, which is itself connected to the suction system (not shown) of the cleaner. Various variants of suction cleaners exist on the market and can be used with the cleaner head 2 according to the invention; such variants are known to the person skilled in the art and are not described in detail in the present patent application.
The cleaning head 2 comprises a main body 4 configured to move over a surface to be cleaned. The connection sleeve 3 is advantageously pivotally mounted relative to the main body 4 so as to allow the main body 4 to pivot forwards and backwards when the cleaner head 2 is moved in the direction of movement D1.
The main body 4 comprises a sole plate 5, said sole plate 5 being equipped with a lower surface 6 configured to be oriented towards the surface to be cleaned and with a suction aperture 7 opening on the lower surface 6. The suction opening 7 communicates with the connection sleeve 3, in particular, via a connection channel 8 which is formed at least partially, for example, by a flexible connection line. The suction aperture 7 may for example have an elongated shape and extend transversely, for example perpendicularly, to the direction of movement D1 of the cleaning head 2.
The main body 4 further comprises a containment casing 9 which opens on the lower surface 6 of the bottom plate 5 via the suction hole 7 and which is fluidly connected to the connection channel 8. Thus, according to the embodiment shown in the figures, the containment casing 9 forms a suction chamber.
The cleaning head 2 further comprises a cleaning element 11 detachably mounted in the accommodating housing 9 and configured to be removed from the accommodating housing 9 in a removal direction D2. Advantageously, the direction of removal D2 extends transversely and preferably perpendicularly to the direction of movement D1 of the cleaner head 2.
According to the embodiment shown in the figures, the main body 4 comprises a passage opening 12 which opens in the accommodating housing 9 and through which the cleaning element 11 can be removed from the accommodating housing 9. Advantageously, said passage opening 12 is provided on the side of the body 4.
According to the embodiment shown in the figures, the cleaning element 11 comprises a rotating brush 13, rotatably mounted in the containment casing 9; and a closing cover 14 configured to at least partially close the passage opening 12 when the cleaning element 11 is mounted in the accommodating case 9.
The cleaning head 2 further comprises drive means 15 configured to drive the rotating brush 13 in rotation about a rotation axis substantially coinciding with the extension axis of the rotating brush 13. The drive means 15 more particularly comprise an electric drive motor 16, the output axis of which may be substantially aligned with the rotation axis of the rotating brush 13 or offset with respect to the rotation axis of the rotating brush 13.
Advantageously, the rotating brush 13 comprises: a first end 13.1 of the brush configured to be rotationally coupled to a drive means 15; and a second end 13.2 of the brush, which is supported by the closure cap 14 and is rotatably mounted with respect to the closure cap 15. According to the embodiment shown in the figures, the drive means 15 comprise a drive belt 17 configured to couple the output shaft of the electric drive motor 16 to a coupling member 18 extending coaxially with the rotating brush 13 and rotationally coupled with the first brush end 13.1 of the rotating brush 13.
Advantageously, the closure cap 14 comprises a grip portion 19 configured to be gripped by a user to allow the cleaning element 11 to be removed from the containment casing 9, and the cleaning head 2 comprises error-proofing means configured to define a relative angular orientation between the closure cap 14 and the body 4 when the cleaning element 11 is inserted into the containment casing 9 via the passage opening 12. According to the embodiment shown in the figures, the error-proofing means comprise a pair of error-proofing elements 21, for example two error-proofing ribs, provided on the closure cap 14, and a pair of error-proofing members 22, for example two error-proofing grooves, provided on the body 4.
In order to ensure that the cleaning elements 11 are locked in the accommodating housing 9, the cleaning head 2 comprises a locking member 23 (see in particular fig. 7) which is elastically deformable and is movably mounted on the main body 4.
According to the embodiment shown in the figures, the locking member 23 is integral and has a substantially L-shaped shape. According to variant embodiments, not shown in the figures, the locking member 23 can be made of a plurality of parts (two or more) reversibly attached together without translational movement between each other (for example by clamping, screwing), or of a plurality of parts irreversibly attached together (for example by gluing, welding, overmoulding).
The locking member 23 more specifically comprises: a first branch forming the control portion 24; a second branch forming a locking portion 25; and a connecting portion 26 that is bent, for example, in a substantially circular arc shape and connects the control portion 24 and the locking portion 25. Advantageously, at least the locking portion 25 is of elongate shape. According to the embodiment shown in the figures, the control portion 24 and the locking portion 25 are each of an elongated shape.
The control portion 24 is slidably mounted on the main body 4 between an inactive position (see fig. 5) and an active position according to a sliding direction D3. Advantageously, the sliding direction D3 extends transversely to the removal direction D2 and extends substantially vertically when the cleaner head 2 is placed on a substantially horizontal support surface.
The locking portion 25 is movable between a locking position (see fig. 5) in which the locking portion 25 cooperates with a locking element 27 provided on the cleaning element 11 (e.g. on the closure cap 14) to prevent the cleaning element 11 from being removed from the accommodating case 9, and a releasing position in which the locking portion 25 releases the locking element 27, thereby allowing the cleaning element 11 to be removed from the accommodating case 9. The locking element 27 may take different forms and may for example be formed by a locking housing, such as a locking groove, a locking stop or a locking shoulder. Advantageously, the locking portion 25 comprises a free end 25.1 configured to cooperate with the locking element 27 in the locking position and to disengage from the locking element 27 in the release position.
According to the embodiment shown in the figures, the control portion 24 and the locking portion 25 are inclined with respect to each other by an inclination angle, and the locking member 23 is configured such that the inclination angle between the control portion 24 and the locking portion 25 has a first value when the locking portion 25 occupies the locking position, and a second value, smaller than the first value, when the locking portion 25 occupies the release position. As a result, when the locking portion 25 is moved from the locking position to the release position, its free end 25.1 moves according to an arc of a circle to disengage from the locking element 27 in the release position. In the example shown in the figures, the free end 25.1 of the locking portion 25 is moved vertically upwards between the locking position and the release position.
The locking member 23 is further configured such that movement of the control portion 24 from the inactive position to the active position causes elastic deformation of the connecting portion 26 and movement of the locking portion 25 from the locking position to the release position. Advantageously, the locking member 23 is configured to elastically push the control portion 24 towards the inactive position and push the locking portion 25 towards the locking position when the locking portion 25 occupies the release position.
According to the embodiment shown in the figures, the cleaning head 2 comprises a stop 28 (see fig. 5) provided on the main body 4 and against which the locking portion 25 abuts when the control portion 24 is moved from the inactive position to the active position. The stop 28 is more particularly configured to cause elastic deformation of the connecting portion 26 when the control portion 24 moves from the inactive position to the active position.
Advantageously, the stop 28 is arranged on one side of the locking portion 25 and the control portion 24 extending from the connecting portion 26 is arranged on the other side of the locking portion 25. This design allows the locking portion 25 to roll over around the stop 28 when the control portion 24 is moved, preferably translated, between the inactive position and the active position. In this configuration, the elastically deformable connecting portion 26 advantageously performs a pivoting function and also ensures that the control portion 24 elastically returns to its inactive position in the absence of stress on the control portion 24.
The stopper 28 is configured to contact the locking portion 25 at two thirds of the length of the locking portion 25. This arrangement makes it possible to limit the force required for unlocking while limiting the internal volume represented by the locking/unlocking mechanism comprising the locking member 23 and the stop 28.
Preferably, the cleaning head 2 and the locking member 23 are designed such that the connecting portion 26 has a larger elastic deformation than the locking portion 25 and a larger elastic deformation than the control portion 24 when the control portion 24 is moved from the inactive position to the active position.
When the control portion 24 is moved from the inactive position to the active position, the control portion 24 and the locking portion 25 undergo negligible elastic deformation compared to the connecting portion 26. In other words, the cleaning head 2 and the locking member 23 are designed such that the connecting portion 26 is preferentially deformed when the control portion 24 is moved from the inactive position to the active position. In addition to the presence of the stop 28, the deformation of the connecting portion 26 can also be facilitated by adjusting the shape and thickness of the control portion 24, the locking portion 25 and the connecting portion 26 of the locking device 23.
According to the embodiment shown in the figures, the cleaning head 2 further comprises an actuation button 29 configured to be actuated by a user, for example with a finger of the user, and movably mounted on the body 4 between a first button position (see fig. 1) and a second button position. According to the embodiment shown in the figures, the actuation button 29 is independent from the locking member 23. However, according to a variant embodiment not shown in the figures, the actuation button 29 can be fixed to the locking member 23 and, for example, to the control portion 24, or the actuation button 29 and the locking member 29 can be made as a single plastic part obtained by pressure injection.
The actuation button 29 and the locking member 23 are configured such that movement of the actuation button 29 from the first button position to the second button position causes movement of the control portion 24 from the inactive position to the active position. To this end, the actuation button 29 comprises an actuation portion 31, for example an actuation finger, which is configured to cooperate with the control portion 24 and, for example, is intended to abut against a pressing portion 24.1 of the control portion 24. Advantageously, the actuation button 29 can be manually operated by the user from the upper surface of the body 4.
In order to remove the cleaning element 11 from the containing casing 9, for example in order to clean the rotating brush 13 or to replace it, the user operates and for example presses the actuation button 29 to move the control portion 24 to the active position and thus the locking portion 25 to the release position and to exert a traction force on the grip portion 19. When the user releases the actuation button 29, the control portion 24 and the locking portion 25 move to the inactive position and the locking position, respectively, because the locking member 23 elastically returns to its original position.
When the user wishes to replace the cleaning element 11 in the containing casing 9, he presses the actuation button 29 to move the locking portion 25 to the release position, inserts the cleaning element 11 in the containing casing 9 until the containing casing is coupled with the coupling member 18, and then releases the actuation button 29 to lock the cleaning element 11 on the main body 4. However, the repositioning of the cleaning element 11 can be simplified by providing an inclined surface on the cleaning element 11, for example on the closure cap 14, which is configured to move the locking portion 25 to the release position when the cleaning element 11 is introduced into the accommodating housing 9 through the passage opening 12.
According to a variant embodiment of the invention, not shown in the figures, the control portion 24 can be actuated directly, manually, from outside the cleaning head 2.
According to another variant embodiment of the invention, which is not shown in the figures, the cleaning element 11 may comprise a brush hood extending at least partially around the rotating brush 13, and the locking element 27 may be provided on the brush hood.
