This patent application claims priority from Italian patent application No. 102019000018212 filed on 10/08/2019.

Technical field of the invention

This invention relates to a floor cleaning device.

Background

In the field of floor cleaning, floor cleaning devices are known, which comprise a stick with a cleaning head at one of its ends; a reservoir for cleaning liquid, normally consisting of a mixture of water and detergent and a basket mounted on the reservoir and fluidly connected to the reservoir to allow the cleaning head to be drained.

Generally, the cleaning head comprises a stick attachment flange to allow the cleaning head to be attached to the stick and multiple bristles; and the basket has multiple holes to smoothly connect the reservoir and the basket.

The known floor cleaning devices described above have some drawbacks, mainly due to the fact that the cleaning liquid contained in the tank is contaminated by dirt discharged from the cleaning head when the latter is rinsed into the tank and when it is wrung out into the tank. of the basket

As a result, the cleaning action is compromised by the rinsing of the cleaning head into the contaminated/dirty cleaning liquid contained in the reservoir.

A cleaning device that offers, in part, a solution to the drawback described above is described in document US 2006/151054 A1 and comprises a stick with a cleaning head at one of its ends, an upper reservoir for a cleaning liquid, a lower tank, and a basket to rinse the cleaning head. The upper and lower reservoirs are separate, and the basket can be fluidly connected to the upper reservoir to receive the cleaning liquid and can be emptied into the lower reservoir after the cleaning head has been rinsed in the basket. This solution, although better than collusion, in which the head is rinsed in the same tank containing the clean cleaning liquid, still has limitations, both in terms of the effectiveness of the rinse and also in terms of the complexity of the operation.

Object and summary of the invention

The purpose of the present invention is to provide a floor cleaning device, free from the drawbacks described above and simple and cheap to manufacture.

According to the present invention, there is provided a cleaning device, as claimed in the appended claims.

Brief description of the drawings

The present invention will now be described with reference to the accompanying drawings, which show a non-limiting embodiment thereof, in which:

Figure 1 is a schematic perspective view, with parts removed for clarity, of a preferred embodiment of the floor cleaning device according to the present invention.

Figure 2 is a schematic perspective view, with parts in cross section and parts removed for clarity, of the floor cleaning device shown in Figure 1; Y

Figures 3 and 4 are two cross sections along the line MI-MI of a detail of the floor cleaning device shown in Figure 1, in two different operating positions.

With reference to figures 1, 2, 3 and 4, the reference number 1 refers, as a whole, to a floor cleaning device, comprising an elongated pole 2 provided with a cleaning head 3 at one of its ends. .

The cleaning head 3 comprises a flange 4 for fixing the cleaning head 3 to the pole 2, and multiple cleaning bristles 5 fixed to the flange 4.

The floor cleaning device 1 further comprises a lower reservoir 6 which, in the embodiment shown, has a cup shape and is delimited at the bottom by a substantially flat and horizontal lower wall 7, and laterally by a vertical side wall 8 substantially vertical.

Floor cleaning device 1 further comprises an upper reservoir 9, which is removably inserted within reservoir 6, extends within reservoir 6, and is designed to contain a cleaning liquid consisting, for example, of a mixture of water and detergent.

The upper reservoir 9 is delimited at the bottom by a substantially flat bottom wall 10 and laterally by a substantially vertical side wall 11.

The upper reservoir 9 is slidably coupled to the lower reservoir 6 and is locked in a substantially vertical direction of insertion 12 by at least one tooth 13, projecting from the side wall 8 into the lower reservoir 6 and extending along of the side wall 8 to keep the side wall 10 at a specific distance from the bottom wall 7.

The upper reservoir 9 is provided with a first basket 14 which, in the embodiment shown, has a cylindrical shape and extends through the upper reservoir 9 and the side wall 10 in the direction of insertion 12, and projects into the lower reservoir. 6.

The first basket 15 is fluidly separated from the upper tank 9, and has multiple connection holes 15, which are formed on the outer side of the upper tank 9 and fluidly connect the basket 14 and the lower tank 6.

The upper reservoir 9 is also provided with a body 16 which, in the embodiment shown, has a cylindrical cup shape, extends through the upper reservoir 9 in the direction of insertion 12, and has a height, measured parallel to the direction of insertion. insertion 12, less than the height of the upper reservoir 9, also measured parallel to the direction of insertion 12.

The body 16 is delimited at the bottom by a bottom wall 17 arranged at a certain distance from the bottom wall 10.

The floor cleaning device 1 further comprises a second basket 18 which, in the embodiment shown, has a cylindrical shape and is supported by the upper reservoir 9, extending through the body 16 and the bottom walls 17 and 10. in the insertion direction 12, and projects into the lower reservoir 6.

The basket 18 is provided with multiple upper connection holes 19 and multiple lower connection holes 20.

The basket 18 is slidably coupled to the body 16 to move between a raised rest position (FIG. 3), where the upper connection holes 19 are arranged inside the body 16 and outside the upper reservoir 9, the lower connection holes 20 are arranged inside the lower reservoir 6 and the lower and upper reservoirs 6, 9 are fluidly separated from each other by the basket 18, and a lowered operating position (figure 4), where the upper connection holes 19 are arranged outside the body 16 and inside of the tank 9, the lower connection holes 20 are arranged inside the tank 6, and the lower and upper tanks 6, 9 are fluidly connected to each other by the basket 18.

Basket 18 normally moves and is held in the raised rest position by the thrust exerted by multiple springs 21 arranged between body 16 and basket 18.

The basket 18 moves from the raised rest position to the lowered operating position by the thrust exerted on the basket 18 by the flange 4 of the cleaning head 3.

In use, the bristles 5 of the cleaning head 3 are wrung into the basket 14 to guide the contaminated/dirty cleaning liquid into the lower reservoir 6 through the connection holes 15.

At this point, the head 3 moves within the basket 18 and the basket 18 is moved from the raised rest position to the lowered operating position by means of the flange 4 to fluidly connect the lower and upper reservoirs 6, 9 to each other and cause that the non-contaminated/clean cleaning liquid in the upper tank 9 flows from the upper tank 9 to the lower tank 6, through the basket 18, thus resulting in the bristle rinsing 5.

In other words, when the basket 18 is moved to the lowered operating position, the uncontaminated/clean cleaning liquid in the upper reservoir 9 flows first into the basket 18 through the upper connection holes 19 and then into the lower reservoir. 6 through the lower connection holes 20.

The floor cleaning device 1 is advantageously compared to known floor cleaning devices, mainly due to the fact that the basket 18 prevents the bristles 5 from immersing into the contaminated/dirty cleaning liquid both in the lower reservoir 6 and also in the uncontaminated/clean cleaning liquid in the upper reservoir 9, and allow the bristles 5 to be rinsed only with the uncontaminated/clean cleaning liquid in the upper reservoir 9.

In alternative embodiments not shown, the basket 14 may be omitted and the bristles 5 may be wrung and rinsed within the basket 18; the basket 18 can be moved from the raised rest position to the lowered operating position directly by a user, for example by means of a foot pedal mechanism and the cleaning head 3 can be replaced with a cleaning head with cleaning elements other than bristles 5.
