All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Environmental sanitation is an important factor influencing the quality of life, so along with the continuous improvement of the requirements of people on the quality of life, the corresponding requirements on environmental sanitation are higher and higher, however, the working pressure of modern people is increased day by day, and people are urgently required to be liberated from heavy cleaning work, so that a plurality of self-moving cleaning equipment for cleaning the ground are provided to improve the environmental sanitation, and a dust collector, a sweeper, a floor washer and the like are commonly used.

For example, floor washers, also known as floor washers and floor suction washers, are cleaning machines that clean hard floors while sucking up and taking away sewage from the site. The floor is suitable for stations, docks, airports, workshops, warehouses, schools, hospitals, restaurants, shopping malls and other places with wide hard floors, and the cleaning concept of replacing manpower with machinery is deep. The hard floor is generally made of terrazzo, marble, granite, artificial stone, floor tile, PVC, carborundum, plastic floor, epoxy, etc. A floor washing machine is an apparatus that cleans by spraying cleaning liquid (e.g., a mixture of water and detergent) while sweeping.

A water tank (a device for storing fluid to be used in cleaning) is an essential device of many cleaning apparatuses (e.g., floor washers), and a better cleaning effect can be achieved by spraying water and wiping, and a detergent is usually added into clear liquid to enhance the dirt removing capability. Because the capacity of the water tank is limited and the water tank is required to be filled with fluid frequently, the fluid filling of the water tank is troublesome at present and can be only carried out through a water pipe, the fluid filling mode is single, and the fluid filling is not convenient enough.

In view of the above problems, embodiments of the present invention provide a cleaning apparatus, which can inject fluid through a water pipe and can inject fluid through a quick-release connector by direct plugging.

And the control device is used for controlling the cleaning device, the fluid storage device 1, the walking device, the spraying device and the sewage recovery device to work.

The cleaning device comprises a brush disc, and the driving device drives the brush disc to rotate so as to clean the ground.

Running gear is including setting up the multiunit gyro wheel in 3 lower parts of main part, and two gyro wheels of every group are located the relative both sides of main part 3 respectively, drive 3 walks of main part through the gyro wheel and carry out cleaning operation.

The spraying device comprises a liquid outlet in fluid communication with the fluid storage device 1 for discharging the cleaning fluid. Optionally, the fluid storage device 1 is connected to the liquid outlet via a cleaning solution output pipeline, and a necessary pump is further disposed on the cleaning solution output pipeline, so that the cleaning solution can be timely and sufficiently delivered to the liquid outlet. In other embodiments, the liquid outlet can also be arranged at the front side of the suction port, so that the liquid outlet is used for directly wetting the surface to be cleaned at the front side of the suction port, the cleaning device is used for brushing the wetted surface to be cleaned, and the brushing effect on the surface to be cleaned can also be achieved. In some embodiments, the fluid storage device 1 can be divided into a plurality of compartments, for example, two compartments, one for storing cleaning fluid and the other for storing recycled sewage; further, in the case of a mixture of clear liquid and detergent, the chamber for storing the cleaning liquid may be divided into two sub-chambers, one sub-chamber having a volume much larger than the volume of the other sub-chamber, such that the larger sub-chamber stores clear liquid and the smaller sub-chamber stores detergent.

The sewage recovery device comprises a fan assembly and a sewage recovery pipeline connected between the sewage recovery device and the suction port. The sewage recovery pipeline sucks impurities and dirty liquid on the surface to be cleaned into the fluid storage device 1 through the sewage recovery pipeline under the action of suction force provided by the fan assembly.

The fluid storage device 1 may be integrally molded using a material such as plastic and may serve as a housing of the main body 3 to improve elasticity, toughness, corrosion resistance and impact resistance of the main body 3 and to reduce the weight of the main body 3. The peripheral wall of the main body 3 can be pre-formed with a plurality of grooves, recesses, blocking positions or the like for installing a spraying device, a sewage recovery device and a walking device. And in case the floor washing machine is used to clean a large place, the volume of the main body 3 can be increased to increase the volume of the fluid storage device 1, so that the fluid storage device 1 has sufficient cleaning solution to meet the washing demand.

In order to make the technical solutions and advantages of the present invention clearer, the following will describe embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, an embodiment of the present invention provides a cleaning apparatus including a fluid storage device 1 for storing a fluid to be used in cleaning; the fluid storage device 1 has a first fluid inlet 21; the first fluid inlet 21 is provided with a cover part 2, the cover part 2 comprises a lower cover 22 and an upper cover 23, the upper cover 23 is detachably connected with the lower cover 22, and the lower cover 22 is provided with a second fluid inlet 223.

Illustratively, the outer sidewall of the second fluid inlet 223 is provided with a junction 2231 for coupling with a coupling (e.g., a quick disconnect coupling) for injecting fluid.

For example, a clear liquid may be injected into the fluid storage device 1 through the first fluid inlet 21, and a detergent may be added to enhance the decontamination capability of the clear liquid. Since the fluid storage device 1 is usually moved together with the cleaning apparatus, the capacity of the fluid storage device 1 may not be particularly large in order to avoid placing an excessive burden on the movement of the apparatus. The fluid storage device 1 needs to be filled with fluid from time to time when cleaning a large area. Accordingly, fluid storage devices require fluid inlets that facilitate the injection of fluids.

The cleaning equipment provided by the utility model can realize fluid injection through a water pipe through the first fluid inlet arranged on the fluid storage device 1, and can also realize direct insertion and connection of the quick-release connector through the second fluid inlet arranged on the cover part to realize fluid injection, so that the diversity of fluid injection modes is realized, and the fluid injection is more convenient.

According to an embodiment of the present invention, the upper cover 23 is provided with an air hole through which the fluid storage device 1 is ventilated when fluid is injected through the second fluid inlet 223. The air holes in the lower cover 22 are located near the outer edge of the cleaning device after the lower cover 22 is tightened.

After the upper cover 23 is closed, since the fluid storage device needs to be sprayed with liquid to the outside during cleaning, an air hole is provided in the upper cover 23 in order to maintain the balance of the atmospheric pressure.

According to the embodiment of the present invention, the upper cover 23 can be detachably connected to the lower cover 22 and also detachably connected to the first fluid inlet 21. Alternatively, the lower cap 22, the upper cap 23 and the first fluid inlet 21 may be detachably connected by a screw connection or a snap connection.

By making the matching manner and the matching dimension of the lower cover 22 and the upper cover 23 consistent with the matching manner and the matching dimension of the lower cover 22 and the first fluid inlet 21, the upper cover 23 can be covered on the lower cover 22 and the first fluid inlet 21, thereby increasing the convenience of covering the fluid inlet.

Illustratively, as shown in FIG. 2, the first fluid inlet 21 is tubular; the lower cap 22 includes a first section 221, a second section 222, and a third section 224 disposed on top of the second section 222 for forming a second fluid inlet 223, the first section 221 having an inner diameter matching an outer diameter of the first fluid inlet 21, and the second section 222 having an outer diameter identical to the outer diameter of the first fluid inlet 21; the upper cap 23 includes a connection portion 231 and a capping portion 232, an inner diameter of the connection portion 231 matches with an outer diameter of the first fluid inlet 21 or with an outer diameter of the second section 222, and the capping portion 232 matches with the second fluid inlet 223.

In an embodiment of the present invention, two fluid inlets (i.e., a first fluid inlet 21 and a second fluid inlet 223) are provided. Optionally, in this embodiment, the first fluid inlet 21 and the second fluid inlet 223 are both tubular, and the diameter of the first fluid inlet 21 is larger than the diameter of the second fluid inlet 223. The first fluid inlet 21 is provided directly on the fluid storage device 1 and the injection of fluid can be performed by directly accessing the injection fluid line, and the first fluid inlet 21 can be covered by the lower cover 22. The lower cap 22 also has a second fluid inlet 223, and the second fluid inlet 223 can be plugged with a quick disconnect to allow direct injection of fluid.

In an embodiment of the present invention, the second fluid inlet 223 is a tube protruding from the second section 222, and the outside of the second fluid inlet 223 is provided with a joint 2231 adapted to be plugged with a quick disconnect for injecting fluid. The second fluid inlet 223 may enable a quick connection with a quick disconnect coupling.

Alternatively, as shown in fig. 1 and 2, in an embodiment of the present invention, the first fluid inlet 21 is externally provided with a first external thread, the first section 221 is internally provided with a first internal thread matching the first external thread, the second section 222 is externally provided with a second external thread, and the connecting portion 231 is provided with a second internal thread matching the first external thread and the second external thread. The above screw-threaded connections are merely exemplary and are not intended to limit the connections between the first fluid inlet 21, the lower cap 22 and the upper cap 23.

The first internal thread in the first section 221 of the lower cap 22 mates with the first external thread of the first fluid inlet 21 on the fluid storage device 1 such that the lower cap 22 may close the first fluid inlet 21. The second section 222 of the lower cap 22 has a second external thread, and the second section 222 has an outer diameter that is the same as the outer diameter of the first fluid inlet 21, and the second external thread of the second section 222 is also substantially identical to the first external thread of the first fluid inlet 21. That is, the second internal thread of the connecting portion 231 of the upper cap 23 may be engaged with the second external thread of the second section 222 of the lower cap 22 or the first external thread of the first fluid inlet 21, and thus the upper cap 23 may be connected to the lower cap 22 or directly to the first fluid inlet 21.

Alternatively, in addition to the threaded connection, the exterior of the first fluid inlet 21 may be provided with a first flange, the interior of the first section 221 is provided with a first groove cooperating with the first flange, the exterior of the second section 222 is provided with a second flange, and the connecting portion 231 is provided with a second groove cooperating with the first flange and the second flange.

The first groove in the first section 221 of the lower cover 22 cooperates with the first flange of the first fluid inlet 21 on the fluid storage device 1 such that the lower cover 22 can cover the first fluid inlet 21. The second section 222 of the lower cap 22 has a second flange, and the outer diameter of the second section 222 is the same as the outer diameter of the first fluid inlet 21, and the second flange of the second section 222 is also substantially identical to the first flange of the first fluid inlet 21. That is, the second groove of the connecting portion 231 of the upper cover 23 may be engaged with both the second flange of the second section 222 of the lower cover 22 and the first flange of the first fluid inlet 21, and thus the upper cover 23 may be connected to both the lower cover 22 and the first fluid inlet 21.

Two covers (an upper cover 23 and a lower cover 22) may be used together to cover the first fluid inlet 21, or the upper cover 23 may be used alone to cover the first fluid inlet 21.

The fluid storage device provided by the utility model can realize fluid injection through the injection fluid pipe through the first fluid inlet 21 arranged on the fluid storage device 1, and can also realize direct insertion and connection of the quick-release connector for fluid injection through the second fluid inlet 223 arranged on the lower cover 22, so that the diversity of fluid injection modes is realized, and the fluid injection of the fluid storage device is more convenient.

Alternatively, as shown in fig. 2, according to an embodiment of the present invention, the second section 222 of the lower cover 22 is provided with a first air hole 2221.

When the fluid is injected through the second fluid inlet 223 of the lower cap 22, if the air in the fluid storage device 1 cannot be discharged in time, the injection fluid speed may be seriously affected because the caliber of the second fluid inlet 223 is small. In an embodiment of the present invention, the first air hole 2221 of the lower cover 22 can be used to exhaust air in the fluid storage device to maintain the atmospheric pressure balance inside and outside the fluid storage device 1, so that fluid can be more rapidly injected into the fluid storage device through the second fluid inlet 223.

As shown in fig. 1 and 2, according to the embodiment of the present invention, the first protrusion 2321 is provided inside the covering part 232, and in the case that the lower cap 22 is coupled to the first fluid inlet 21 and the upper cap 23 is coupled to the lower cap 22, the first protrusion 2321 protrudes into the second fluid inlet 223, so that the second fluid inlet 223 can be covered by the first protrusion 2321.

When the fluid storage device 1 sprays liquid, the air holes arranged on the cover meet the requirement of ventilation, and when the fluid storage device 1 discharges the liquid, the air holes through which the outside air passes enter the fluid storage device, so that the smoothness of the liquid flowing in the fluid storage device 1 is ensured.

As shown in fig. 1 to 3, according to the embodiment of the present invention, the second air hole 2323 is disposed at the top of the covering portion 232 of the upper cover 23, and a first gap 4 is formed between the first protrusion 2321 and the sidewall of the second fluid inlet 223.

In the case where the upper cover 23 is coupled to the lower cover 22 and the lower cover 22 is coupled to the first fluid inlet 21, a passage through which air inside the fluid storage device flows out to the outside may be achieved through a gap between the first protrusion 2321 and the second fluid inlet 223, and then the air may be discharged to the outside of the fluid storage device through the second air hole 2323 of the upper cover 23.

In the case where only the upper cover 23 is connected to the first fluid inlet 21, the fluid storage device 1 may be directly ventilated through the second air hole 2323 of the upper cover 23.

Since the cleaning apparatus needs to travel with the fluid storage device 1 during operation, the liquid in the fluid storage device 1 may continuously shake up and down and left and right during the travel, and thus the liquid splashed from the fluid storage device 1 may overflow from the air hole of the cover.

In an embodiment of the present invention, especially in the case where the upper cover 23 is connected to the lower cover 22 and the lower cover 22 is connected to the first fluid inlet 21, in order to avoid liquid in the fluid storage device 1 from escaping from the air vent, an S-shaped vent path is established (as shown in fig. 3).

Exemplarily, in an embodiment of the present invention, the inside of the closure 232 is further provided with a second protrusion 2322 spaced apart from the first protrusion 2321, a sidewall of the second fluid inlet 223 is located between the first protrusion 2321 and the second protrusion 2322, and a second gap 5 is provided between a top surface of the sidewall and the inner top surface of the closure 232. That is, the sidewall of the second fluid inlet 223 does not abut against the top surface of the covering portion 232, and a gap is left between the two to facilitate the circulation of the gas.

A third gap 6 is provided between the sidewall and the second protrusion 2322, and this gap is also for ensuring the gas to flow through, and the second protrusion 2322 also provides an obstacle to the liquid to overflow.

The second air hole 2323 is adjacent to the second protrusion 2322 and located outside the second protrusion 2322 in the radial direction of the covering portion 232, and the first gap 4, the second gap 5, the third gap 6 and the path from the third gap 6 to the second air hole 2323 together form an S-shaped air passage (as shown in fig. 3).

Optionally, one or more second air holes 2323 may be provided on the upper cover 23. The second air holes 2323 are each located radially outward of the second protrusion 2322.

When the liquid overflows due to shaking, the overflow path of the liquid is generally a straight path, and if the path of the air vent is also a straight path, the liquid easily overflows from the second air hole 2323. In an embodiment of the present invention, the first gap 4, the second gap 5, the third gap 6 and the path from the third gap 6 to the second air hole 2323 together form an S-shaped air passage, so that the liquid is difficult to overflow from the S-shaped air passage, and the problem of overflow of the liquid from the air hole due to shaking of the fluid storage device is avoided.

Alternatively, the length of the second protrusion 2322 may be increased, making it possible to more effectively prevent the overflow of the liquid.

As shown in fig. 1, in an embodiment of the present invention, a first fluid inlet 21 is integrally formed with the fluid storage device 1, and the first fluid inlet 21 is disposed obliquely with respect to a horizontal plane.

The first fluid inlet 21 has a certain inclination angle, which is more ergonomic and easier to operate manually, so that the injection fluid tube can be inserted into the first fluid inlet 21 more easily.

For example, a clear liquid may be injected into the fluid storage device 1 through the first fluid inlet 21, and a detergent may be added to enhance the decontamination capability of the clear liquid. Since the fluid storage device will typically move with the cleaning apparatus, the capacity of the fluid storage device 1 may not be particularly large in order to avoid placing an excessive burden on the movement of the apparatus. The fluid storage device 1 needs to be filled with fluid from time to time when cleaning a large area. Accordingly, fluid storage devices require fluid inlets that facilitate the injection of fluids.

The fluid injection can be realized through the water pipe through the first fluid inlet arranged on the fluid storage device, and the fluid injection can also be realized through the second fluid inlet arranged on the cover part and directly inserted into the quick-release connector, so that the diversity of fluid injection modes is realized, and the fluid injection is more convenient.

The cover part 2 comprises a lower cover 22 and an upper cover 23, the upper cover 23 being detachably connectable to said lower cover 22 and also to the first fluid inlet 21. Alternatively, the lower cap 22, the upper cap 23 and the first fluid inlet may be detachably connected by a screw connection or a snap connection.

By making the matching way and the matching size of the lower cover 22 and the upper cover 23 consistent with the matching way and the matching size of the lower cover and the first fluid inlet, the upper cover 23 can cover the lower cover 22 and the first fluid inlet 21, thereby increasing the convenience of covering the fluid inlet.

Two fluid inlets are provided (i.e., a first fluid inlet 21 and a second fluid inlet 223). The first fluid inlet 21 and the second fluid inlet 223 are both tubular, the first fluid inlet 21 having a larger diameter than the second fluid inlet 223. The first fluid inlet 21 is provided directly on the fluid storage device 1 and the injection of fluid can be performed by directly accessing the injection fluid line, and the first fluid inlet 21 can be covered by the lower cover 22.
