Description

CLEANING DEVICE AND METHODS FOR USE THEREOF

FIELD The present subject matter relates to cleaning devices. More particularly, the present subject matter relates to cleaning devices retaining a cleaning liquid.

BACKGROUND A sponge is a cleaning device widely used for cleaning surfaces. A sponge is a soft, porous material that is capable of absorbing a cleaning liquid, like water, a liquid detergent, liquid soap, and the like. After a cleaning liquid is absorbed by the sponge, a surface is rubbed by the sponge, and the physical forces exerted during rubbing together with the absorbing nature of the sponge and the cleansing effect of the cleaning liquid absorbed by the sponge remove dirt from the surface. Normally, a cleaning liquid is absorbed by a sponge by pouring the cleaning liquid onto the sponge, or immersing the sponge in a container full with a cleaning liquid. However there are cases when there is a need to clean a surface with a sponge absorbing a cleaning liquid, but there is no access at that time to a source of cleaning liquid, like a faucet for water. In other cases it is impossible to use a container full with a cleaning liquid for immersing in it the sponge. For example, during driving a motorcycle there is a need to clean the windshield or the helmet visor with a sponge soaked with a cleaning liquid. Obviously, it is impossible to pour a cleaning liquid on a sponge, or immerse the sponge in a container full with a cleaning liquid, during the ride. Therefore, there is a need for a cleaning device that enables cleaning of a surface in cases when there is no access to a source of a cleaning liquid or when is it impossible to immerse the cleaning device in a container full with a cleaning liquid.

When assembly 3 is pressed down in order to release the locking element 178 and remove assembly 3, the absorbent liquid retaining element 120 is pressed against the absorbent cleaning element 110, and as a result some cleaning liquid flows from the absorbent liquid retaining element 120 to the absorbent cleaning element 110. Thus, when assembly 3 is released from the housing 160, it is ready for cleaning a surface, since there is a cleaning liquid in the absorbent cleaning element 110. Furthermore, after assembly 3 is released from the housing 160, the pressure exerted on the absorbent liquid retaining element 120 is relieved. As a result, excess cleaning liquid is absorbed again by the absorbent liquid retaining element 120, due to its high absorption capability, leaving in the absorbent cleaning element 110 an appropriate amount of cleaning liquid for cleaning a surface. According to a preferred embodiment, the cleaning device 1 comprises the following components assembled and connected according to embodiments described above: an absorbent cleaning element 110, an absorbent liquid retaining element 120, a support 130, a gripping element 140, a wiper 150, a housing 150 and an attachment element 170. An assembled and connected cleaning device 1 comprising these components is illustrated in Fig. 16.

According to another preferred embodiment, the cleaning device 1 illustrated in Fig. 16 is configured to be used by a motorcycle rider to clean the windshield of the motorcycle, or preferably the helmet visor, during riding. The cleaning device 1 is suitable for this purpose because a cleaning liquid is stored in the absorbent liquid retaining element 120, and while removing assembly 3 from the housing 160, an appropriate amount of cleaning liquid is transferred to the absorbent cleaning element 110, making it ready for cleaning during the ride, without a need to stop riding or getting to a facility, like a gas station, for cleaning the windshield or the helmet visor.

Furthermore, the cleaning device 1 is preferably attached to a surface of a motorcycle within reach of a hand of a motorcycle rider, as described above, in order to allow easy and comfortable usage of the cleaning device 1, during the ride.

In addition, when needed, a cleaning liquid may be added to the absorbent liquid retaining element 120. Furthermore, any component of the cleaning device 1 may be replaced with a new one in case it becomes worn out, due to the modularity of the cleaning device 1 as described herein.
