Description

Floor cleaning tool

Technical Field

The disclosure belongs to the technical field of cleaning equipment, and particularly relates to a ground cleaning tool capable of self-cleaning.

Background

With the development of modern technology, floor cleaning tools have been diversified, including brooms, mops, floor wipers, dust collectors, and the like. The cleaner is a very conventional floor cleaning tool, but the cleaner is very noisy and uncomfortable. And the garbage is cleaned only by sucking the garbage into the garbage box.

Brooms, mops and floor wipers are cleaning tools of the mop type, which generally have a fixed cleaning part, the cleaning capacity of which is determined by the dirt removing and absorbing capacity of the cleaning part. Since the cleaning portion is contaminated as soon as it comes into contact with the soiled floor, the cleaning power is gradually reduced during the subsequent cleaning process, and complete cleaning cannot be achieved, particularly when a large area is continuously swept. Therefore, the cleaning articles must be washed frequently, which is very troublesome.

For Chinese consumers, sweeping and mopping are necessary when cleaning the floor, and the floor cannot be thoroughly cleaned only by sweeping or mopping. However, these existing mopping and sweeping all-in-one machines either need to be washed continuously, or have complex structures and high manufacturing cost, so that ordinary consumers are prohibited.

Furthermore, existing floor cleaning tools can only clean dry waste (brooms, cleaners, etc.) or can only be used to clean liquid waste (mops, floor mops, etc.). It is said to be unwarranted by the hand that the cleaning of dry and wet mixed waste, in particular sticky waste (such as syrup, ketchup, etc.), is either particularly poor or very laborious (e.g. with rags, requiring multiple washes).

In addition, the mopping machine or the mopping and sweeping all-in-one machine can be provided with a water tank for storing water. The existing water tanks are generally of a simple box-like structure and are fixedly mounted on the machine, and water squeezed out of the drum may overflow to the ground and be inconvenient to clean.

Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

In the description of the present disclosure, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present disclosure can be understood in specific instances by those of ordinary skill in the art.

The terms "first," "second," and the like in the description and claims of the present disclosure and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference in the present disclosure to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present disclosure. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described in the present disclosure can be combined with other embodiments.

FIG. 1 illustrates a water tank 231 for a floor cleaning tool according to the present disclosure. It includes: a water storage tank 231a and a water guide tank 231 b. The water storage tank 231a is provided with a first water inlet for storing water. The bottom surface of the water guide groove 231b is inclined and wedge-shaped, and is provided with a second water inlet and a water outlet. Wherein, the second water inlet is wide, and the water outlet is narrow. The water outlet is connected with the water inlet of the water storage tank 231 a. The water squeezed from the drum of the floor cleaning tool flows into the water storage tank 231a through the water guide groove 231b by its own weight.

The water guide groove 231b is constructed such that the water pressed from the drum flows smoothly into the water storage groove 231b without overflowing to the ground.

The water tank 231 shown in fig. 1 further includes a wiper strip 231c therein. The wiper strip 231c is disposed at the first water inlet of the water guide groove 231b to guide the water pressed down from the drum 111 into the water guide groove 231 b. Optionally, the leading end of the wiper strip 231c is attached to the drum 111 (as shown in FIG. 3), which is configured to minimize the flow of squeezed-out water along the drum 111 to the place or other components of the floor cleaning tool. In other embodiments of the present disclosure, the leading end of the wiper strip 231c may also interfere with the drum 111, and thus there is no gap between the drum 111 and the leading end of the wiper strip 231 c. Alternatively, the wiper strip 231c is made of a flexible rubber material so that it can be better attached to the drum 111. The interference of the leading end of the wiper strip 231c with the drum 111 means that the leading end partially presses the surface of the drum 111.

When the floor cleaning tool is operated, water in the water storage tank 231a is easily shaken, so that water may flow back from the water storage tank 231a to the upper end (first water inlet end) of the water guide tank 231b to overflow onto the floor or other parts of the floor cleaning tool. When the reservoir 231a is filled with water, the water is more likely to overflow, causing the floor cleaning tool to fail. In order to prevent water from flowing backward from the water storage tank 231a to the first water inlet of the water guide groove 231b, a water bar (not shown) may be provided on the water guide groove 231 b. The water bar of the present disclosure is close to the upper end of the water chute 231b, and has a certain height and a certain length, and the height and the length can be set according to actual needs. The water bar is preferably disposed in the middle of the water guide groove 231b with both sides spaced apart from the sidewalls of the water guide groove 231 b.

The sewage squeezed out of the drum 111 generally contains fine solid garbage, and in order to prevent the solid garbage from blocking the water inlet of the water storage tank 231a and the water storage tank 231a, a filter assembly for filtering the garbage in the water can be installed at the water inlet of the water storage tank 231 a. In the embodiment shown in fig. 1, the filter element is a filter plug 231 d. The water in the water guide 231b flows into the water storage tank 231a through the filter plug 231d, thereby filtering most of the solid garbage. Preferably, the filter plug 231d is detachably mounted at the water inlet of the sump 231a, so that the filter plug 231d can be easily cleaned. The greater the height of the filter plug 231d (which may be the same as the height of the water storage tank 231a at most), the more garbage it can hold, and the specific height can be set according to the requirement.

In other embodiments of the present disclosure, the filter assembly may also be a filter net installed at the water inlet of the water storage tank 231 a. The water in the water guide 231b flows into the water storage 231a through the filter screen, thereby filtering most of the solid garbage. In this case, the filter screen is not detachable and needs to be cleaned by other tools.

In the present disclosure, the water tank 231 may be detachable and only used for storing water, and may be directly poured out when the water is full. Or fixed on the floor cleaning tool, and at this time, the water storage tank 231a is also provided with a water outlet. The purified water filtered by the filtering component can be reused on the roller by a power device (such as a water pump), so that the water can be recycled.

When the floor cleaning tool works, the roller can be provided with solid garbage, large garbage can enter the garbage can of the floor cleaning tool under the action of self weight, but small garbage is difficult to separate from the roller, and if the garbage is not separated first, a large amount of small garbage can be contained in sewage extruded from the roller. In order to separate the garbage from the drum, the water tank 231 of the present disclosure may further include a brush 231 e. Fig. 2 is an enlarged view of the portion a shown in fig. 1, and the structure of the brush 231e can be clearly seen. The brushes 231e are provided in one or more rows below the water guide groove 231b and above the garbage can, and when the water tank is mounted to the floor cleaning tool, the bristles of the brushes 231e are in contact with the surface of the drum 111, and when the drum is rotated, the brushes 231e rub against the drum, thereby brushing the garbage from the drum into the garbage can.

3-5 illustrate a preferred embodiment of a floor cleaning tool of the present disclosure including the water tank 231 described above. It includes a housing 500, a drum 111, a water pressing bar 122, a water tank 231, and a water pump 233. The floor cleaning tool of the present disclosure is used for cleaning floors, particularly smooth, flat, small area floors, such as household and kitchen floors. The floor cleaning tool of the present disclosure is particularly suitable for cleaning mixed waste (sticky waste) mixed with dry waste, wet waste and stickies such as noodles, porridge, tomato ketchup and the like.

Wherein the drum 111 is mounted on the case 500. The drum 111 has at least two layers, and the outermost layer is a sponge layer for absorbing water and cleaning garbage. The innermost layer is a supporting layer and made of hard materials, and the driving motor can be sleeved in the roller 111, so that the space can be saved, and the size of the ground cleaning tool can be reduced.

The roller 111 may be detachably provided (as shown in fig. 8) with a catch 111d at one end thereof to facilitate detachment from the housing 500. The motor 113a is installed inside the drum 111, and the rotation shaft 113c is installed on the housing 500. The motor 113a drives the hard material inside to rotate around the axis thereof through the transmission mechanism, and drives the sponge layer 111b to rotate, so that the surface of the sponge layer 111b makes circular motion.

The density and hardness of the sponge layer 111b of the roller 111 have a direct influence on the water absorbing property and the water retaining rate (also referred to as water lock). When the density of the sponge is improved to a certain extent, the water absorption performance is reduced, the hardness is improved, and the water storage rate is improved; on the contrary, the sponge density is reduced, the water absorption is improved, the hardness is reduced, and the water storage rate is reduced.

In some embodiments of the present disclosure, the sponge layer 111b may be made of polyvinyl alcohol (PVA) foam. The density of the PVA sponge is 0.5-0.25 g/cm³The water absorption rate is 0.5-1.5 g/cm³. The Shore hardness of the PVA sponge is 40-70. The water storage rate of the PVA sponge is 0.2-1.0 g/cm³. Such a sponge layer, because it possesses above-mentioned characteristic, consequently with the ordinary sponge cylinder contrast of current individual layer, has more excellent effect:

the sponge layer has proper water absorption performance and water storage rate and also has proper density and hardness, so that the sponge can deform properly to wrap garbage particles in the mopping process, and most garbage particles can be ejected out by utilizing the elasticity of the sponge layer to be separated from the sponge layer and fall into the dry garbage collection unit without omission when the sponge layer is rotated to be limited by the shovel strips; moreover, when the accumulated water on the ground is treated, the sponge can absorb more water, and less water is remained on the dragged bottom surface.

The single-layer sponge layer can avoid the defect that the service life of the roller is influenced because the double-layer sponge layer is extruded and separated from the layer.

Alternatively, the sponge layer 111b is generally 3 to 15mm thick and deformed enough to wrap the usual granular trash. Household cleaning tools are provided with a sponge layer with the thickness of 5-10 mm, and common dry garbage on the household ground can be treated.

Fig. 7 is a schematic view of the motor 113a in the floor cleaning device without the roller 111 according to an embodiment of the disclosure.

The water pressure bar 122 is disposed inside the housing 500 to interfere with the sponge layer of the drum 111 (as shown in fig. 3) to press out water in the sponge layer of the drum 111. The upper end of the water pressure bar 122 is provided with a water spray opening for spraying water to the sponge layer of the drum 111, thereby cleaning the sponge layer of the drum 111. The water spray nozzles may be arranged in one or more rows, or may be arranged as a water spray channel with a wide upper end and a narrow lower end as shown in fig. 3.

In the embodiment shown in fig. 3-8, the water tank 231 is fixed on the floor cleaning tool, and the water storage tank 231a is further provided with a water outlet. The purified water filtered by the filtering component can be reused on the roller through the power device, so that the water can be recycled.

In the embodiment shown in fig. 3-8, the power plant is a water pump 233. The water pump 233 is installed inside the housing 500, and has one end connected to the water outlet of the water tank 231 through the first water pipe 232a and the other end connected to the water outlet of the water pressing bar 122 through the second water pipe 232 b. In the embodiment shown in fig. 1 to 3, two second water pipes 232b are connected to the left and right ends of the water pressure bar 122, respectively, so that the sprayed water is more uniform.

The water pressing bar 122 extrudes the sponge layer of the roller 111, and the extruded sewage flows into the water guiding groove 231b under the guidance of the scraping bar 231c, is filtered by the filter plug 231d, and then enters the water outlet groove 231 a. The purified water obtained after filtration is reused under the action of the water pump 233, and the drum 111 is cleaned again. The above-mentioned processes are repeated to achieve the cleaning effect on the roller 111. Except that clear water needs to be added into the water tank when the floor cleaning tool is used for the first time, the water in the floor cleaning tool can be recycled, and the self-cleaning effect is achieved.

The floor cleaning tool disclosed by the invention is simple in structure, almost has no noise when in use, and can realize the recycling of water.

The floor cleaning tool shown in FIGS. 3-8 further includes a trash bin 141 and a shovel bar 112.

The dustbin 141 is mounted on the case 500 below the water guide groove 231 b. This arrangement saves space. The garbage can 141 can be detachably installed to facilitate cleaning.

The shovel bar 112 has an arc-shaped working surface, one end of which is in contact with the ground when working, and a uniform gap is formed between the arc-shaped working surface and the outer circumference of the drum 111 at a certain distance, and the gap forms a garbage passage through which solid garbage swept from the ground enters the garbage can 141.

When the roller 111 rolls on the ground, the sponge layer 111b is pressed and deformed by the particles of the dry garbage on the ground, and the particles of the dry garbage are wrapped by the sponge layer 111b through deformation, so that the particles of the dry garbage are separated from the ground and rotate together with the roller 111. When turned to the position of the shoveling bars 112, the particles of the dry waste leave the ground, are squeezed by the shoveling bars 112, and continue to rotate with the drum 111. When the garbage box is rotated to the entrance of the garbage box 141 after passing the shovel strip 112, the sponge layer 111b is restored to deform due to the loss of the compression of the shovel strip 112, and the dry garbage particles wrapped by the sponge layer are released and are ejected into the garbage box 141.

The floor cleaning tool of the present disclosure may further include at least two wheels 150, the wheels 150 being mounted at the bottom of the water tank 231 to move the floor cleaning tool forward or backward.

In addition, the floor cleaning tool of the present disclosure may also include a hand-held portion (not shown in the figures). The hand-held portion is connected to the housing 500 and a user grasps the hand-held portion to move the floor cleaning tool forward or backward to clean the floor. The switch of the water pump 233 may be provided on the handle.

The housing at the end of the floor cleaning tool of the present disclosure where the roller 111 is mounted may also be provided with a bumper strip (not shown) to prevent the housing 500 from being damaged by impact during the floor cleaning process.

The floor cleaning tool of the present disclosure, except for the drum 111 and the wheels 150, does not contact the floor.

The floor cleaning tool disclosed by the invention can effectively clean liquid garbage and can realize self-cleaning of the roller. When being equipped with rubbish box and shovel strip, can also clear up large granule solid refuse.

In some embodiments of the present disclosure, the user adds fresh water to the water tank 231, holds the handle, turns on the switch of the water pump 233, and activates the water pump 233. The water pump 233 pumps the water in the water storage 231a to the water spray opening of the water pressure bar 122 to spray the water onto the sponge layer of the drum 111. The user pushes the floor cleaning tool forward and backward and the drum 111 moves accordingly. The sponge layer on the drum 111 is slightly wet (unsaturated in water absorption) before contacting the ground, and after contacting the ground, the slightly wet sponge layer absorbs the liquid garbage on the ground and cleans the solid garbage on the ground. The sticky garbage adheres to the sponge layer.

With the help of the shoveling bars 112, the large solid garbage carried up by the rollers 111 reaches the garbage can 141 through the gap between the shoveling bars 112 and the garbage can. The small garbage particles are embedded or adhered on the sponge layer, and along with the movement of the roller 111, the small garbage particles reach the brush 231e, and under the action of the brush 231e, the small garbage particles or hairs embedded or adhered on the sponge layer are brushed down and enter the garbage can 141 under the action of the self weight.

The drum 111 continues to roll to the pumping bar 122. The pressurized water barrier strip 122 extrudes the sponge layer to extrude the sewage in the sponge layer. The upper end of the water pressing barrier 122 continuously sprays water, and the lower end continuously presses the sponge layer of the roller 111, which is equivalent to that the water pressing barrier 122 continuously cleans the roller 111 in the use process of the floor cleaning tool. The viscous waste is released from the sponge layer 111b of the drum 111 to the sewage. The extruded sewage is guided to the water guide groove 231b by the scraper 231c, and then filtered by the filter plug 231d to enter the water outlet groove 231 a. The filtered purified water is reused by the water pump 233, and is pumped to the water jet of the water pressure barrier 122 to clean the drum 111. The above steps are continuously circulated, and the ground is cleaned.

In the disclosure, water can be circulated for multiple times, and garbage (dust) can be cleaned smoothly, and the disclosure refers to the technology as water-dust circulation cleaning technology.

It should be understood that the above examples are only for clearly illustrating the present disclosure, and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention as herein taught are within the scope of the present disclosure.
