Embodiments of the present application provide a surface cleaning system including a wet surface cleaning apparatus and a cleaning base upon which the surface cleaning apparatus rests. For convenience of explanation, the vertical floor washing machine will be described as an example.

Referring to fig. 1, in one embodiment of the present application, a surface cleaning system is provided that includes a surface cleaning apparatus 100 and a cleaning base 200 upon which the surface cleaning apparatus 100 may rest.

Wherein the surface cleaning apparatus 100 comprises: the cleaning machine comprises a vertical machine body 150, a grab handle 140 connected to the machine body 150, a rolling brush assembly 110 positioned at the bottom of the machine body 150, a cleaning liquid supply assembly, a cleaning main machine 120, a sewage recovery box 130 and the like.

Specifically, the machine body 150 adopts a vertical structure, and the lower part of the machine body is rotatably connected with the rolling brush assembly 110, so that a user can conveniently adjust the angle between the machine body 150 and the rolling brush assembly 110, and can conveniently push the equipment to move on the ground. The upper part of the body 150 is connected with a handle 140, which is convenient for a user to push the cleaning device to move or turn on the floor, and a plurality of keys 141 for the user to operate the device are arranged on the handle 140.

In the present embodiment, the cleaning main unit 120 and the dirty liquid recovery tank 130 are detachably connected to the front side of the machine body 150 one above the other, respectively, so that a user can manually pour the dirty water in the dirty liquid recovery tank and the dust in the dust canister after the floor cleaning operation is completed. The cleaning main unit 120 is detachable from the main body 150 according to the user's requirement, and when the surface cleaning apparatus is used as an upright type cleaning apparatus, the cleaning main unit 120 is connected to the main body 120 to work, and when the cleaning main unit 120 is removed from the main body 150, the cleaning main unit 120 can be connected to an accessory or used as a hand-held cleaner alone.

In alternative embodiments, the cleaning main unit 120 may be fixedly attached to the main body 150, in which case the dust cartridge 121 of the cleaning main unit 120 may be detached independently for pouring dust.

In other embodiments, the cleaning main unit 120 and the dirty liquid recovery tank 130 may be integrally and fixedly connected to the main body 150, and the dirty liquid is discharged and the dust is emptied through the cleaning base 200 only when the surface cleaning apparatus is parked on the cleaning base 200.

The surface cleaning apparatus may further comprise a cleaning liquid supply assembly. The cleaning liquid supply assembly includes a cleaning water tank 160 detachably connected to the rear side of the main body 150, and a clean water distribution line connecting the cleaning water tank 160 and the rolling brush assembly, which can uniformly distribute the cleaning liquid to the rolling brush 111 or the floor to be cleaned. In some preferred embodiments, the cleaning solution supply assembly may further include a water pump and a heater connected in series in the clean water distribution line. The heater may be used to heat the cleaning liquid or form steam for spraying to the roller brush or floor to sterilize or heat.

Referring to fig. 2 and 3, the dirty liquid recovery tank 130 has a dirty liquid inlet 132 and an air outlet 133 above the dirty liquid inlet 132. In this embodiment, the dirty liquid recovery tank 130 may be detachably mounted on the machine body 150, and after the cleaning operation is finished, the user may remove the dirty liquid recovery tank 130 from the machine body 150 and manually pour the dirty liquid.

In some embodiments, the dirty liquid recovery tank 130 may also be fixedly mounted to the machine body 150 and automatically drain the dirty liquid in the dirty liquid recovery tank 130 by resting on a cleaning base. Still further, the dirty liquid recovery tank 130 may also perform an automatic cleaning by resting on the cleaning base.

With continued reference to fig. 2, the bottom of the dirty liquid recovery tank 130 may also be provided with a liquid drain 134. The liquid discharge port 134 is located below the dirty liquid inlet 132, and when the surface cleaning apparatus rests on the cleaning base, the liquid discharge port 134 can interface with the wet blowdown mechanism 220 of the cleaning base, so as to transfer the dirty water in the dirty liquid recovery tank to the cleaning base via the wet blowdown mechanism, or directly discharge the dirty water.

The cleaning main unit 120 includes a vacuum motor 122 for providing vacuum suction and a dust barrel 121 with an air inlet, and the dust barrel 121 has a dust separating device therein. To enhance the ease of use of the surface cleaning apparatus, the cleaning host 120 may further include a battery pack electrically connected to the vacuum motor 122, through which the vacuum motor is powered when the cleaning host 120 is detached from the body 150, so that the cleaning host can be used alone.

Referring to fig. 3, the rolling brush assembly 110 includes a housing 117 forming part of an outer surface of the rolling brush assembly, a rolling brush 111 in frictional contact with a surface to be cleaned, and a dust suction port 118 provided at a periphery of the rolling brush 111. In some embodiments the suction opening may be provided in the form of a flat suction opening as is common in the art to suck away large debris from the floor to reduce the ingress of solid debris into the wet debris chamber. In other embodiments, a stirring roller may be provided at the suction opening to rub against the floor and assist in transporting dust from the floor into the dry waste chamber.

The rolling brush 111 can be a rolling brush commonly used in wet cleaning equipment, and the surface of the rolling brush is covered with water absorbing materials or brush hair. The roller brush 111 is wetted with the cleaning liquid dispensed by the cleaning liquid supply assembly, and wipes and cleans the surface to be cleaned by friction with the floor. The sewage on the roll brush 111 is finally sucked into the sewage recovery tank 130 by vacuum.

In order to prevent dry dust, hair and the like from wetting, the application arranges a dust suction port 118 for sucking dry dust at the periphery of the rolling brush 111 and is separated from the rolling brush 111, so that the dry dust of dust, hair and the like on the surface to be cleaned can be transferred to the dust barrel 121 by the vacuum motor 122 before contacting with the rolling brush 111. The dust collection opening can be arranged on the front side of the rolling brush or on the front side and the rear side of the rolling brush at the same time, so that when the surface cleaning equipment moves on the surface to be cleaned, the surface to be cleaned passes through the dust collection opening and then passes through the rolling brush.

In this embodiment, there are two flat dust collection openings, which are respectively located on the front side and the rear side of the roller brush, and the dust collection openings 118 are parallel to the axial direction of the roller brush. When the front side and the rear side of the rolling brush are provided with dust collection openings, the front side dust collection opening or the rear side dust collection opening can be automatically selected and opened through the valve plate, namely, when the surface cleaning equipment advances forwards, the front side dust collection opening is automatically opened, and the rear side dust collection opening is automatically closed; when the surface cleaning apparatus travels rearward, the rear side dust collection port is automatically opened, while the front side dust collection port is automatically closed.

Referring to fig. 3, further, the rolling brush assembly has a dry garbage chamber 112 and a wet garbage chamber 113 isolated from each other by air flow, the rolling brush 111 is disposed in the wet garbage chamber 113, and the dust suction opening is disposed at an opening of the dry garbage chamber 112 facing the surface to be cleaned.

The surface cleaning apparatus 100 has a first fluid passage 114 communicating with the wet waste chamber 113, the dirty liquid recovery tank 130 and the vacuum motor 122, and a second fluid passage 115 communicating with the dry waste chamber 112, the air inlet of the dust canister 121 and the vacuum motor 122. The first fluid channel 114 and the second fluid channel 115 are at least partially isolated from each other, so that a dry garbage recycling path which does not pass through the dirty liquid recycling bin 130 is formed between the dust collection opening 118 and the air inlet of the dust barrel 121, that is, dry garbage on the surface to be cleaned can directly enter the dust barrel 121 through the dust collection opening, the dry garbage cavity 112 and the second fluid channel 115 and is separated from dust in the dust barrel, thus the dry garbage can be completely prevented from being infiltrated by water vapor, the dust collection effect and the dust separation effect are affected, and meanwhile, the water vapor is prevented from being combined with dust in the dust barrel and adhered to the inner surface of the dust barrel after entering the dust barrel.

In the specific implementation, the dry garbage cavity 112 and the wet garbage cavity 113 may be constructed by a part of a housing of the rolling brush assembly or may be constructed by a third component.

Specifically, a brush chamber for accommodating the brush 111 is formed in the housing 117, and the brush 111 is rotatably connected to the housing 117 about its axis. In the present embodiment, the housing 117 is provided with the partition 116 inside, and the partition 116 is substantially arc-shaped and covers the outside of the roller brush 111. The partition 116 divides the roller brush chamber into two dry waste chambers 112 and wet waste chambers 113 that are isolated from each other by air flow. The inside of the partition 116 forms the wet garbage cavity 113, and the rolling brush 111 is positioned in the wet garbage cavity 113; the outer wall surface of the partition 116 and the inner wall surface of the housing 117 together define the dry waste chamber 113. The partition 116 is provided with an air flow hole through which the wet garbage chamber 113 is communicated with the first fluid passage 114, and the lower end of the second fluid passage 115 is directly connected to the inner wall of the housing and is communicated with the dry garbage chamber 133.

In this embodiment, the first fluid channel 114 is located at the front side of the second fluid channel 115, so that a part of the second fluid channel 115 may be opened on the body 150.

It should be understood that the number/shape of the spacers provided by the embodiments of the present application is not limited, and although 1 spacer is shown in fig. 2 and 3 and curved, the spacers may be formed by combining a plurality of members in other embodiments of the present application. Likewise, the application is not limited to the number of brushes, e.g. the brush assembly comprises a pair of brushes, and the divider is suitably arranged to accommodate the shape of the pair of brushes, as long as it is ultimately able to build up two chambers in the brush assembly that are dry and wet separated.

To improve the dust collection efficiency and the sealing performance, the partition 116 may be provided with a flexible strip 1161, such as a rubber strip, a wool strip, or the like, at a portion close to the floor.

To avoid excessive liquid in the wet waste chamber from dripping to the surface to be cleaned, the roller brush assembly 110 may further include a baffle 1162 and a wiper strip 1163 disposed in the wet waste chamber 113. One or two baffle plates 1162 may be provided and extend in the axial direction of the roller brush, and the baffle plates may prevent the liquid thrown onto the inner wall surface of the partition member by the roller brush from flowing back to the ground. The scraping strip can be in friction contact with the bristles of the roller brush to help remove excess dirt from the surface of the roller brush. The wiper strip 1163 is located upstream of the first fluid channel 114 in the rotational direction of the roll brush so that the dirty liquid scraped off by the wiper strip is sucked up via the first fluid channel.

Because the dry garbage is transferred into the dust barrel through the dust collection opening, the dry garbage cavity and the second fluid channel at the first moment of contacting the surface to be cleaned, the dry garbage in the dust barrel can be ensured to be dry, the dry garbage is not easy to adhere to the surface of the dust barrel, and the dust is easy to pour.

In the embodiment shown in fig. 2, the first fluid passage 114 and the second fluid passage 115 are completely isolated and merge only in the motor chamber into the vacuum motor 122, thereby ensuring that no moisture is present in the dust canister. In other embodiments, a filter may be disposed at the air outlet 133 of the dirty liquid recovery tank 130 to sufficiently remove water vapor in the air discharged from the dirty liquid recovery tank 130, and the filtered water vapor may be combined with the dust-containing gas in the second fluid channel 115 and enter the dust canister 121, that is, the first fluid channel and the second fluid channel may share a pipeline downstream of the dirty liquid recovery tank.

In the embodiments of the present application, the surface cleaning apparatus may be provided with a plurality of modes of operation including: dry cleaning mode, wet cleaning mode, and hybrid cleaning mode.

The surface cleaning apparatus further includes a first valve mechanism for regulating the flow of the first fluid passage 114 and the second fluid passage 115 and a controller that receives external instructions to control the first valve mechanism to perform specified actions. The first valve mechanism may selectively open or close the first fluid passage 114, the second fluid passage 115, or both. The first valve mechanism may be disposed in a region between the downstream of the dust canister 121 and the upstream of the vacuum motor 122.

When the surface cleaning apparatus is in the dry cleaning mode, the first valve mechanism acts to close the first fluid passage 114 and the second fluid passage 115 therethrough, and the surface cleaning apparatus can be used as a vacuum cleaner.

When the surface cleaning apparatus is in the wet cleaning mode, the first valve mechanism acts to open the first fluid passage 114 and the second fluid passage 115 is closed, and the surface cleaning apparatus can be used as a floor cleaning machine.

When the surface cleaning apparatus is in the hybrid cleaning mode, the first valve mechanism acts to allow both the first fluid passage 114 and the second fluid passage 115 to pass through, and the surface cleaning apparatus can perform both dry and wet mopping operations on the floor.

The first valve mechanism may be implemented by various structures, and includes at least one first valve sheet capable of closing the first fluid passage and the second fluid passage, and a first driver driving the first valve sheet to move forward and backward. The first valve plate may be a hollow part, for example, a valve hole is formed in the first valve plate, and when the valve hole is communicated with the inner cavity of the first fluid channel or the second fluid channel, the first fluid channel or the second fluid channel is penetrated.

The structure of the first valve mechanism in one embodiment of the application is shown in fig. 4. As shown, the first valve mechanism 151 includes at least one first valve plate 1512 capable of closing the first and second fluid passages, and a first driver 1511 that drives the first valve plate to move forward and backward. The first driver 1511 is in signal communication with the controller, the first valve plate 1512 is a solid member capable of shielding the fluid passages, the first valve plate 1512 has three operating positions, an initial position is between the first fluid passage and the second fluid passage, the first fluid passage 114 can be closed forward, the second fluid passage 115 can be closed backward, and the first fluid passage 114 and the second fluid passage 115 can be opened simultaneously when maintained in the initial position shown in fig. 4.

Fig. 5 is a schematic structural view of a first valve mechanism according to still another embodiment of the present application. In this embodiment, the first valve mechanism 151 includes a first valve plate 1512 and a first driver 1511 that can drive the first valve plate 1512 to rotate, where the first valve plate 1512 is also a solid component, and can selectively cover any one fluid channel, so as to realize switching of two fluid channels.

With continued reference to fig. 3, the bottom of the dirty liquid recovery tank 130 further has a liquid drain 134 and a second valve mechanism 131 capable of closing the liquid drain 134. The second valve mechanism may adopt the structure design of the conventional floor washing machine with the automatic drainage cleaning function, for example, the second valve mechanism 131 may include a second valve plate and a second driver for driving the second valve plate to open or close, and the second driver is in signal connection with the controller. The controller is configured to open the second valve mechanism to drain liquid from the dirty liquid recovery tank when the surface cleaning apparatus is placed on the cleaning base 200.

In the preferred embodiment of the present application, the dust canister 121 has an openable dust cover that is manually opened by a user to remove dust, and in addition, the dust canister 121 has a dust discharge port and a third valve mechanism capable of closing the dust discharge port, the third valve mechanism being configured to be opened when the surface cleaning apparatus is placed on the cleaning base 200 to empty the dust canister of dry waste. In a simplified embodiment, the third valve mechanism may be a one-way valve plate which closes the dust discharge opening when the surface cleaning apparatus is in normal operation; when the surface cleaning apparatus is placed on the cleaning base 200, the valve plate can be lifted off by a mechanical plug-in connector, thereby placing the dust canister in air flow communication with the dust collector interior cavity in the cleaning base.

The cleaning base 200 has a dry waste recycling device 230 for receiving dry waste, which interfaces with the dust canister, and a wet drain mechanism 220 for receiving or draining waste liquid, which interfaces with the waste liquid recovery tank. The cleaning base may further include a self-cleaning spray structure for spray cleaning the dirty liquid recovery tank, which may be constructed as known in the art, for example, the self-cleaning spray structure may be connected to a municipal tap water pipe and may extend the spray head into the dirty liquid recovery tank for flushing the dirty liquid recovery tank when the surface cleaning apparatus is docked in the cleaning base.

The dry garbage recycling apparatus 230 includes a suction motor 231, a dust collector 232, and a docking port to dock with the dust discharge port, which are provided in the housing 210.
