Description

Cleaning head equipped with wet cleaning device
Technical Field
The present invention relates to the field of cleaning heads intended to clean surfaces, and more particularly to a vacuum cleaner equipped with a suction head which allows to suck in dust and small-sized waste present on a surface to be cleaned, and to enable wet cleaning of the surface to be cleaned.
Background
Suction cleaners equipped with a suction head which allow cleaning of surfaces by suction to remove dust and small-particle-size waste deposited on these surfaces are well known on the market. The surface to be cleaned may be, for example, a tile floor, a laminate, a carpet or a carpet.
For cleaning smooth floors, and in particular for removing stains present on smooth floors, it is known, in particular from document CN110101336A, to equip the suction head with a wet cleaning device.
This wet cleaning apparatus includes:
-a mop support on which a mop is mounted;
-a cleaning liquid reservoir located above the mop support and configured to supply cleaning liquid to a mop mounted on the mop support, the cleaning liquid reservoir comprising a liquid outlet provided in a lower portion of the cleaning liquid reservoir;
-a closing member extending along an extension axis and being movably mounted along the extension axis relative to the cleaning liquid reservoir between a closing position in which the closing member closes the liquid outlet and a releasing position in which the closing member releases the liquid outlet;
-a lower annular sealing joint mounted on a lower portion of the closure member and configured to prevent the cleaning liquid from flowing through the liquid outlet when the closure member occupies the closed position; and
an upper annular sealing joint mounted on the upper portion of the closure member and which is therefore axially offset with respect to the lower annular sealing joint along the extension axis of the closure member.
The upper and lower annular sealing joints are annular and are each configured to apply a radial force to an inner surface of a tubular mounting portion provided on the cleaning liquid reservoir in which the closure member is mounted translationally movably.
Thus, when the closure member is moved between the released and closed positions, significant friction is generated between the lower and upper annular sealing joints and the tubular mounting portion. However, such friction makes it difficult to move the closure member between the release position and the closure position, and more particularly to operate an actuating member by a user, the actuating member being configured to move the closure member between the release position and the closure position, and on the other hand, such friction requires the presence of an oversize biasing member to bias the closure member towards the release position.
Disclosure of Invention
The present invention aims to overcome all or part of these disadvantages.
The technical problem on which the present invention is based consists in particular in providing a cleaning head provided with a wet cleaning device of reliable and economical construction, while ensuring easy movement of the closing member of the wet cleaning device.
To this end, the invention relates to a cleaning head comprising a wet cleaning device comprising:
-a mop support on which a mop is mounted;
-a cleaning liquid reservoir located above the mop support and configured to supply cleaning liquid to a mop mounted on the mop support, the cleaning liquid reservoir comprising a liquid outlet provided in a lower portion of the cleaning liquid reservoir;
-a closing member extending along an extension axis and mounted translatably movable in a translational direction substantially parallel to the extension axis with respect to the cleaning liquid reservoir between a closing position, in which the closing member closes the liquid outlet, and a releasing position, in which the closing member releases the liquid outlet;
-a lower annular sealing joint arranged substantially coaxially to the extension axis and configured to prevent the flow of cleaning liquid through the liquid outlet when the closure member occupies the closed position; and
-an upper annular sealing joint disposed substantially coaxially to said extension axis and axially offset with respect to said lower annular sealing joint along said extension axis of said closure member.
The upper annular sealing joint is configured to effect sealing by axial contact between a first annular surface provided on the closure member and a second annular surface provided on the cleaning liquid reservoir when the closure member occupies the closed position.
In other words, when the closure member occupies the closed position, the upper annular sealing joint is configured to axially cooperate with a first annular surface provided on the closure member and a second annular surface provided on the cleaning liquid reservoir and effect a seal between the first and second annular surfaces.
This configuration of the upper annular sealing joint allows for a significant reduction in the force exerted by the upper annular sealing joint on the cleaning liquid reservoir when the closure member is moved between the release position and the closed position, and thus allows for convenient user operation of an actuating member configured to move the closure member between the release position and the closed position. In addition, this configuration of the upper annular sealing joint does not require the presence of an oversized biasing member to bias the closure member towards the release position and therefore reduces the manufacturing costs of the wet cleaning apparatus.
The upper annular sealing joint is more particularly configured to avoid, in the event of the cleaning head being overturned, the cleaning liquid flowing between the closure member, mounted translatably in the mounting housing, and the mounting housing.
