The cleaning base 1 further defines a pair of suction nozzles 17 located internally and adjacent to the pair of roller cavities 12, respectively, each suction nozzle 17 being in fluid communication with a respective side of the roller cavity 12. The suction nozzle 17 forms an inlet to a fluid inlet path (see below) for the suction flow to carry the dirty liquid on the surface to be cleaned into the fluid inlet path. Further, the cleaning base 1 is further provided with a wiper plate 18 respectively located at the lower sides of the pair of fluid dispensers 15, each wiper plate 18 being respectively located at the upper sides of the pair of suction nozzles 17 and configured to be able to contact the outer surface of the first brush roller 13 or the second brush roller 14 to scrape off the dirty liquid carried by the corresponding brush roller.
Referring to fig. 10 to 11, the housing 11 has a side wall 111, and the driving mechanism includes a driving motor 191 as a power source, a reduction gearbox 192 mechanically coupled to the driving motor 191, first and second driving heads 194 and 195 rotatably mounted on the side wall 111 and disposed in front and rear, and first and second transmission assemblies. One side end parts of the first brush roller and the second brush roller are respectively and fixedly arranged on the first driving head and the second driving head, so that the first driving head and the second driving head can respectively drive the first brush roller and the second brush roller to rotate.
The drive motor 191, the reduction gearbox 192 and the side wall 111 are fixedly connected in sequence. The driving motor 191 is located at the inner side of the housing 11 and is disposed between the first and second brush rolls to reduce the overall volume of the cleaning base 1. The reduction gearbox 192 includes a box body (not shown) fixedly disposed on the side wall 111, and a reduction gearbox output shaft 193 protruding from the box body and extending into the side wall 111, where the reduction gearbox output shaft 193 is configured to be simultaneously connected to the first and second driving heads in a transmission manner, so as to simultaneously drive the first and second brush rollers to rotate under the driving of the driving motor 191.
Specifically, a first transmission assembly is disposed within the interior of the side wall 111 for effecting a transmission connection between the reduction gearbox output shaft 193 and the first drive head 194. The first transmission assembly comprises a first transmission belt 196 and a first transmission gear 197, wherein the first transmission belt 196 is sleeved on the outer sides of the first transmission gear 197 and the reduction gearbox output shaft 193, and the first transmission gear 197 is coaxially arranged with the first driving head 194 through a coupler so as to drive the first driving head 194 and the first brush roller 13 to rotate in a first rotation direction R1.
A second transmission assembly is arranged inside the side wall 111 for effecting a transmission connection between the gearbox output shaft 193 and the second drive head 195. The second transmission assembly comprises a second transmission gear 199 and a third transmission gear 1910 which are coaxially arranged, a fourth transmission gear 1911 meshed with the third transmission gear 1910, and a second transmission belt 198 sleeved outside the reduction gearbox output shaft 193 and the second transmission gear 199. The fourth transmission gear 1911 is coaxially disposed with the second driving head 195 through a coupling to drive the second driving head 195 and the second brush roller 14 to rotate in a second rotation direction R2 opposite to the first rotation direction R1.
During actual use of the surface cleaning apparatus 100, the first brush roller 13 positioned on the front side and the second brush roller 14 positioned on the rear side are not in the same cleaning environment, and the first brush roller 13 generally supplies more cleaning liquid, faces a surface to be cleaned with a higher degree of dirt, generates more dirt liquid, and the like than the second brush roller 14. Thus, the first and second brush rolls are generally given different rotational speeds to adapt to the cleaning environment in which they are exposed, due to factors such as energy utilization and cleaning ability. It can be appreciated that the surface cleaning apparatus 100 provided in the present application can adjust the rotation speeds of the first and second brush rolls by setting the radius length of each transmission gear on the cleaning base 1, the transmission ratio of the third transmission gear to the fourth transmission gear, and so on. The rotation speed of the second brush roller 14 in this embodiment is lower than that of the first brush roller 13.
With continued reference to fig. 1, the upright body 2 extends in a longitudinal direction and includes a handle portion 21 at the top, a connecting end 23 at the bottom, and a main body portion 22 between the handle portion 21 and the connecting end 23. The handle portion 21 is provided with a grip 211 for being held by a user and a number of first control keys (not shown) located on the grip 211 and in signal connection with controllable components of the surface cleaning apparatus 100 for the user to control the operation of the surface cleaning apparatus 100.
In connection with fig. 9, the base body 11 of the cleaning base 1 is further provided with a hinge seat 112 at the top and a rotatable joint 113 hinged to the hinge seat 112, the rotatable joint 113 being located in the fluid input path and being in fluid communication with each suction nozzle 17. The connecting end 23 is fixedly connected to the rotatable joint 113 of the cleaning base 1, and the rotatable joint 113 can provide a rotation range of at least 90 degrees, so that a user can adjust the angle between the upright machine body 2 and the cleaning base 1 based on actual requirements. For example: the upright body 2 is adjusted to be perpendicular to the cleaning base 1 (see fig. 1) so as to store the surface cleaning apparatus 100; the upright body 2 is adjusted to be inclined backward relative to the vertical line so that a user holds the handle 211 and pushes the cleaning base 1 to move on the surface to be cleaned; or the upright volume 2 is adjusted to be at 90 deg. to the vertical (figure 5) in order to clean the surface to be cleaned in highly confined areas such as the bed bottom, sofa bottom etc.
The cleaning liquid tank 4 is for storing and supplying cleaning liquid to the outside, and is detachably installed at the lower front side of the main body portion 22 so that a user can add cleaning liquid thereto. The surface cleaning apparatus 100 defines a liquid supply path (not shown) for cleaning liquid from the cleaning liquid tank 4 to a pair of fluid distributors 15. A selectively actuatable liquid supply pump (not shown) is provided in the liquid supply path to selectively deliver cleaning liquid from the tank 4 to a pair of fluid distributors 15 and to block fluid flow in the liquid supply path.
Referring to Figs. 6 to 8, the portable vacuum cleaner 3 is configured to be integrally detachable from the upright body 2 and to be used independently as a dry vacuum cleaner. The portable vacuum cleaner 3 includes a housing 31, a handle 32 integrally formed with the housing 31 and for a user to carry the portable vacuum cleaner 3, an air inlet pipe 33 defining an axis Y, a gas-solid separator 34, a suction motor 35 for forming a suction flow, a rechargeable battery 37 arranged at the top, and a plurality of exhaust ports 312 provided in an array at the side of the housing 31 for the suction flow to flow out of the portable vacuum cleaner 3. Wherein the handle 32 is arranged at the front side of the housing 31 and is provided with a number of second control keys (not shown) for a user to control the portable vacuum cleaner 3. When the portable vacuum cleaner 3 is mounted on the upright body 2, the handle 32 is exposed forward to facilitate the user's disassembly and assembly of the portable vacuum cleaner 3.
The housing 31 includes a dirt cup 313 and an air inlet bypass 36 disposed to one side of the dirt cup 313. The dirt cup 313 is configured to be removable from the portable vacuum cleaner 3 for a user to dump debris from the dirt cup 313. The dust cup 313 defines a dust collection chamber 38, and the air inlet duct 33 is integrally formed with the dust cup 313 and extends partially into the dust collection chamber 38. The air inlet pipe 33 has a first end and a second end which are far away from each other, and the first end protrudes outwards relative to the dust cup 313 and forms an air inlet 331 for sucking and flowing into the portable dust collector 3; the gas-solid separator 34 is disposed within the dust collection chamber 38, and a second end of the air inlet tube 33 is fixedly disposed on the gas-solid separator 34 and in fluid communication with an upper portion of the dust collection chamber 38.
The gas-solid separator 34 is of a rotationally symmetrical structure and is arranged coaxially with the intake pipe 33. The gas-solid separator 34 includes a connecting portion (not shown) which is away from the gas inlet pipe 33 and fixedly provided on the inner wall surface of the housing 31, a skirt (not shown) which is close to the gas inlet pipe 33, a filter portion (not shown) which is located between the connecting portion and the skirt, and a filter chamber 39 which is defined inside the filter portion. The skirt extends outwardly relative to the filter portion and divides the dirt collection chamber 38 into an upper chamber and a lower chamber that are in fluid communication.
The filter section is cylindrical in configuration, and the gas-solid separator 34 is provided with a plurality of filter holes (not shown) arranged in an array in the filter section, and the filter chamber 39 is in fluid communication with the suction motor 35. The air inlet tube 33, dust collection chamber 38, filter aperture, filter chamber 39, and suction motor 35 are in fluid communication in sequence and form a first vacuum path for suction flow from the air inlet 331 to the suction motor 35. Further, a first filter 310 is disposed in the filter chamber 39 (i.e., between the dust collection chamber 38 and the suction motor 35) in the first vacuum path to further adsorb micro debris passing through the filter apertures.
The intake bypass 36 is independent of the dust collection chamber 38 and comprises a first section 362 arranged alongside the dust cup 313 and a second section 363 arranged perpendicularly to the first section, the second section 363 being located between the suction motor 35 and the first filter 310. The first link 362 is formed with a bypass port 361 exposed from one side of the dust cup 313 and is provided with a door mechanism 311 located at the bypass port 361. The portable vacuum cleaner 3 is formed with a second vacuum path for the suction flow from the bypass port 361 to the suction motor 35. The door mechanism 311 is normally closed to close the bypass port 361 when the portable vacuum cleaner 3 is detached from the upright body 2. Specifically, the door mechanism 311 provided in this embodiment includes a baffle (not shown) adapted to the bypass opening and an elastic restoring member (such as a torsion spring, not shown) for applying an urging force to the baffle, and when the portable vacuum cleaner 3 is used independently, the baffle keeps closing the bypass opening 361 under the action of the elastic restoring member.
The suction motor 35 is disposed in the middle of the inner side of the housing 31, and a plurality of exhaust ports 312 which are disposed in an array and through which suction flows out of the portable vacuum cleaner 3 are formed in the side portion of the housing 31. A plurality of exhaust ports 312 are disposed at the lower side of the suction motor 35 to lengthen the exhaust path as much as possible, thereby reducing exhaust noise. When the portable vacuum cleaner 3 is mounted on the upright body 2, the exhaust port 312 is hidden (i.e., the exhaust port 312 is located inside the surface cleaning apparatus 100 and surrounded by the upright body 2) to further reduce exhaust noise.
The rechargeable battery 37 may be used as a power source for the portable vacuum cleaner 3 or the surface cleaning apparatus 100. Specifically, when the portable vacuum cleaner 3 is mounted on the upright body 2, the rechargeable battery 37 is electrically connected with each energy consuming component of the surface cleaning apparatus 100 to supply electric power to the surface cleaning apparatus 100; when the portable vacuum cleaner 3 is detached from the upright body 2, the rechargeable battery 37 is electrically connected only to the various energy consuming parts of the portable vacuum cleaner 3 to supply the portable vacuum cleaner 3 with electric power.
When the portable vacuum cleaner 3 is used independently as a dry vacuum cleaner, the bypass port 361 is closed by the door mechanism 311, and the suction motor 35 is activated and forms a suction flow to suck debris on the cleaning surface. The suction flow carrying the debris flows in from the air inlet 331 and along the first vacuum path, and the gas-solid separator 34 blocks the debris within the dust collection chamber 38 to effect gas-solid separation. The blocked debris falls into the lower chamber due to gravity and the like, and the skirt of the gas-solid separator 34 can block debris in the lower chamber from entering the upper chamber when the portable cleaner 3 is tilted or inverted. The suction flow of detached debris then reaches the suction motor 35 via the filter chamber 39 and finally exits the portable cleaner 3 via the plurality of exhaust ports 312.
Referring to fig. 2 to 3, a mounting seat 221 for mounting the portable vacuum cleaner 3 is provided on the main body 22 of the upright body 2. The mounting base 221 is provided with a trigger piece 222 and a groove (not shown) corresponding to the bypass port 361 and the air inlet 331 respectively, a butt port (not shown) for the suction flow to flow out of the upright body 2 is formed on the trigger piece 222, and a closing mechanism 223 capable of closing the air inlet 331 when the portable dust collector 3 is mounted on the upright body 2 is arranged in the groove. The surface cleaning apparatus 100 defines a fluid input path for suction flow from each suction nozzle 17 to the counter-interface. When the portable vacuum cleaner 3 is mounted on the upright body 2, the mounting base 221 is in contact with the portable vacuum cleaner 3; the trigger 222 pushes the gate mechanism 311 at the bypass port 361 to switch on the fluid input path and the second vacuum path; the air inlet 331 is located at the recess and is closed by a closing mechanism 233 to close the first vacuum path. Specifically, the triggering member is a boss capable of pushing up the baffle, and the closing mechanism 233 is a sealing ring adapted to the air inlet 331. In other embodiments, the closing mechanism may be implemented using other structures, such as a step mechanism that blocks the air inlet or a groove that is configured to conform to the outer contour of the air inlet (or the contour of the housing around the air inlet).
A contaminated fluid recovery tank 5 is detachably mounted to the lower portion of the upright body 2 and forms part of the fluid input path to receive and store contaminated fluid carried by the suction flow. Specifically, the dirty liquid recovery tank 5 defines a dirty liquid chamber 51 for receiving and containing the dirty liquid, an inflow tube 52 for fluid to enter the dirty liquid chamber 51, an outflow channel 53 for fluid to exit the dirty liquid recovery tank 5 and at the top, and a baffle 54 on the upper side of the inflow tube 52. The inflow tube 52, the dirty liquid chamber 51 and the outflow channel 53 are in fluid communication in sequence and form part of a fluid input path, and a baffle 54 is located in the fluid input path and adjacent downstream of the inflow tube 52. When the suction flow carrying the dirty liquid enters the dirty liquid cavity 51 from the inflow pipe 52, the capacity is expanded and the pressure is reduced, most of the dirty liquid is separated from the suction flow and stored in the dirty liquid cavity 51, and a small part of the dirty liquid flows to the baffle plate 54 in a carrying way by the suction flow, and the liquid-gas separation is completed at the baffle plate 54 under the action of inertia. The suction flow then flows out of the dirty liquid recovery tank 5 via the outflow channel 53 (in this case, a small amount of moisture is thrown away). Further, a second filter 55 is provided on the upright body 2 in the fluid input path, and the second filter 55 is located between the dirty liquid recovery tank 5 and the docking port to further absorb the dirty liquid and dirt carried by the suction flow.
The following illustrates the working principle of the surface cleaning apparatus 100: when the surface cleaning apparatus 100 performs cleaning operation, the portable vacuum cleaner 3 is mounted on the upright body 2, the liquid supply pump is started, and the cleaning liquid in the cleaning liquid tank 4 flows to the pair of fluid distributors 15 along the liquid supply path and wets the corresponding first brush roller 13 or second brush roller 14; the first brush roller and the second brush roller clean the surface to be cleaned by using cleaning liquid; the suction motor 35 is activated and creates a suction flow which carries the dirty liquid on the surface to be cleaned from the pair of suction nozzles 35 into the surface cleaning apparatus 100 and thence via the fluid inlet path and the second vacuum path to the exhaust port 312 and thence out of the surface cleaning apparatus 100. During this process, the contaminated liquid is stored in the contaminated liquid recovery tank 5.
It will be appreciated that during operation of the surface cleaning apparatus 100, the suction flow carrying a small amount of moisture may bypass the dust collection chamber 38 and the gas-solid separator 34 via the second vacuum path to avoid moisture from combining with debris stored in the dust collection chamber 38 such that the debris becomes sticky and blocks the first vacuum path.
The foregoing embodiments are merely illustrative of the technical concept and features of the present application, and are intended to enable those skilled in the art to understand the content of the present application and implement the same according to the content of the present application, not to limit the protection scope of the present application. All equivalent changes or modifications made in accordance with the spirit of the present application are intended to be included within the scope of the present application.
