[0081] Figure 1 Schematic diagram of the structure of a surface cleaning device according to one embodiment of the present disclosure. Figure 2 2 is a schematic structural diagram of a surface cleaning device according to an embodiment of the present disclosure from another angle.

[0082] like Figure 1 and Figure 2 As shown, the surface cleaning device 100 of the present disclosure is used to clean a surface to be cleaned. Preferably, the surface cleaning device 100 can perform wet cleaning on the surface to be cleaned and recover the liquid after cleaning the surface to be cleaned to the surface cleaning device 100 .

[0083] Specifically, the surface cleaning device 100 can clean the surface to be cleaned by frictional contact between the agitator 150 and the surface to be cleaned, and during the frictional contact between the agitator 150 and the surface to be cleaned, cleaning liquid can be provided to the agitator 150, thereby achieving wet cleaning of the surface to be cleaned.

[0084] After wet cleaning of the surface to be cleaned, on the one hand, there will be water stains on the surface to be cleaned, and on the other hand, there will be sewage in the agitator 150, which will make the agitator 150 dirty and affect the subsequent cleaning effect; based on this, it is necessary to recycle the water stains on the surface to be cleaned and the sewage in the agitator 150 to the surface cleaning device 100, and provide clean cleaning liquid to the agitator 150 again.

[0085] In the present disclosure, the above functions are achieved through the fluid distribution system 110 and the fluid recovery system 120 .

[0086] Specifically, if Figure 1 and Figure 2 As shown, the surface cleaning apparatus of the present disclosure includes components such as a fluid distribution system and a fluid recovery system.

[0087] Figure 3 Schematic diagram of a fluid distribution system according to one embodiment of the present disclosure.

[0088] like Figure 3 As shown, the fluid distribution system 110 is used to store cleaning liquid and can distribute the stored cleaning liquid to the agitator 150. For example, the fluid distribution system 110 includes a distribution channel 111, a water outlet 112 and a supply tank 113, and the supply tank 113 and the water outlet 112 at least partially define the distribution channel 111.

[0089] In the present disclosure, the supply tank 113 is formed in a box shape to store the cleaning liquid in the supply tank 113. In one embodiment, the cleaning liquid can be purified water or a mixture of water and detergent.

[0090] The distribution channel 111 is connected to the supply tank 113 and the water outlet 112 to provide the cleaning liquid in the supply tank 113 to the water outlet 112 through the distribution channel 111. In one embodiment, a pump device may be provided on the distribution channel 111 so that the cleaning liquid in the supply tank 113 is provided to the water outlet 112 after being pressurized and sprayed outward through the water outlet 112, thereby allowing the cleaning liquid to be evenly distributed on the outer peripheral surface of the agitator 150.

[0091] In one embodiment, the surface cleaning device 100 may include a frame portion 130, wherein a accommodating space is formed on the frame portion 130, and the supply tank 113 can be arranged in the accommodating space, so that a portion of the outer surface of the supply tank 113 forms a part of the outer surface of the surface cleaning device 100.

[0092] In the present disclosure, the supply tank 113 can be disassembled from the frame portion 130 and manually filled with cleaning liquid by the user; of course, the supply tank 113 of the present disclosure can also be filled with cleaning liquid through a cleaning liquid interface provided on the frame portion 130.

[0093] Furthermore, when a cleaning liquid interface is provided on the frame portion 130 , the supply tank 113 may be provided inside the frame portion 130 , and in this case, the supply tank 113 does not form at least a portion of the outer surface of the surface cleaning apparatus.

[0094] Figure 4 and Figure 5 Schematic diagram of the structure of a fluid distribution system according to different embodiments of the present disclosure.

[0095] like Figure 4 and Figure 5As shown, the surface cleaning apparatus 100 in the present disclosure further includes a heating system 115 , wherein the heating system 115 is configured to heat the cleaning liquid and provide the heated cleaning liquid to the agitator 150 .

[0096] In a preferred embodiment, the heating system 115 can be provided in the distribution channel 111 and formed as a part of the fluid distribution system 110. In a specific embodiment, the heating system 115 can be formed as a thick film heater, which can provide not only hot water but also steam.

[0097] From the position above, such as Figure 4 As shown, the heating system 115 can be provided on the pipeline between the supply tank 113 and the pump device 114, that is, the cleaning liquid provided by the supply tank 113 is provided to the pump device 114 after being heated and pressurized by the pump device 114. Figure 5 As shown, the heating system 115 can also be arranged in the pipeline between the pump device 114 and the water outlet 112. That is to say, the cleaning liquid provided by the supply tank 113 is pressurized by the pump device 114 and then provided to the heating system 115. Therefore, the pump device 114 can be selected as a conventional peristaltic pump, etc.

[0098] Figure 6 Schematic diagram of the structure of a fluid recovery system according to one embodiment of the present disclosure.

[0099] In this disclosure, Figure 6 As shown, the fluid recovery system 120 includes a recovery channel 121 , a suction nozzle 122 and a recovery tank 123 . The recovery tank 123 and the suction nozzle 122 at least partially define the recovery channel 121 .

[0100] In one embodiment, the suction nozzle 122 may be provided in the cleaning portion 140 and located behind the agitator 150 to facilitate collection of wastewater after the agitator 150 cleans the surface to be cleaned.

[0101] The recovery channel 121 is partially located in the cleaning portion 140 and partially located in the frame portion 130, and the recovery tank 123 is located in the frame portion 130. For example, the frame portion 130 is formed with a receiving space, and the recovery tank 123 is detachably mounted on the frame portion 130, so that when a large amount of liquid is stored in the recovery tank 123, the user can remove the recovery tank 123, pour out the sewage inside, and clean up the solid waste. In this case, a portion of the outer surface of the recovery tank 123 forms part of the outer surface of the surface cleaning device 100.

[0102] Of course, those skilled in the art should know that the recovery tank 123 can also be non-detachably set on the frame part 130, for example, set inside the frame part 130. In this case, the sewage in the recovery tank 123 needs to be discharged outward through the sewage interface set on the frame part 130.

[0103] In this disclosure, Figure 6 As shown, the surface cleaning device 100 further includes an airflow accelerator 160, which is in fluid communication with the fluid recovery system 120 to achieve forced flow of gas in the recovery channel 121 through the airflow accelerator 160. In one embodiment, the airflow accelerator 160 can be a suction device that can generate a negative pressure that can be applied to the recovery tank 123, thereby allowing the gas to flow from the suction nozzle 122 to the recovery tank 123, and thereby causing the sewage to flow in this direction. More preferably, the airflow accelerator 160 is in fluid communication with the suction nozzle 122 for generating working gas that flows through the recovery path during the self-cleaning cycle.

[0104] Refer again Figure 1 and Figure 2 The surface cleaning device 100 of the present disclosure may include a cleaning portion 140, which is pivotally connected to the frame portion 130, wherein the agitator 150 can be formed as a part of the cleaning portion 140. Accordingly, the cleaning portion 140 may also include a driving component for driving the agitator 150 to rotate, etc., which will not be described in detail here.

[0105] In other words, the cleaning portion 140 and the agitator 150 together form a cleaning base, and the surface cleaning device 100 cleans the surface to be cleaned through the cleaning base.

[0106] Figure 7 1 is a schematic structural diagram of a cleaning portion and an agitator 150 according to one embodiment of the present disclosure.

[0107] like Figure 7 As shown, the cleaning portion 140 includes a removable cover 141 , and the cleaning portion 140 is formed with an accommodating cavity, and the agitator 150 is rotatably (autorotatably) disposed in the accommodating cavity.

[0108] Figure 8 1 is a partial structural diagram of a cleaning portion and an agitator according to one embodiment of the present disclosure.

[0109] The cover body 141 includes a first edge 1411 and a second edge 1412 away from the first edge 1411 . A continuous and smooth inner surface is formed between the first edge 1411 and the second edge 1412 , and the continuous and smooth inner surface at least partially forms the accommodating cavity.

[0110] Among them, as a focus of the present invention, a water outlet 112 is formed on the inner surface of the cover body 141, and the water outlet 112 is arranged on a continuous and smooth surface; thus, through the position setting of the water outlet 112, dirt will not accumulate at the position of the water outlet 112, and when the surface cleaning device of the present invention is actually used, there is no need to disassemble and clean the agitator 150, which improves the user experience.

[0111] In the present disclosure, the agitator 150 can be formed in the form of a roller brush. Preferably, the outer surface of the agitator 150 has fluff. The agitator 150 is arranged in the accommodating cavity of the cleaning part 140 and is located in the fluid distribution system and the fluid recovery system, and the rotation axis of the agitator 150 is laterally arranged close to the suction nozzle 122.

[0112] In other words, because of the presence of the fluff of the agitator 150, when the fluff is upright in the radial direction, the agitator 150 has a first diameter; correspondingly, when the fluff is not upright in the radial direction, for example, when at least a portion of the fluff extends circumferentially, the agitator 150 has a second diameter; those skilled in the art should know that the first diameter is greater than the second diameter.

[0113] Moreover, if Figure 8 As shown, the surface cleaning device of the present disclosure also includes an agitator cleaning member 190, which is detachably arranged along the first edge 1411; the agitator cleaning member 190 is configured to be arranged at a position below the water outlet 112 and not on the continuous smooth surface, so that when the agitator 150 rotates in a first direction, the wet fluff of the agitator 150 does not interfere with and rub against the smooth and continuous inner surface, and when the agitator rotates in a second direction, the wet fluff of the agitator 150 interferes with and rubs against the smooth and continuous inner surface. In the present disclosure, the size or installation position of the agitator cleaning member 190 is set to always interfere with the agitator 150; that is, no matter whether the agitator 150 rotates in the first direction or the second direction, the agitator cleaning member 190 is in contact with the fluff of the agitator 150. Accordingly, when the agitator 150 rotates in the first direction, the agitator cleaning member 190 can smooth the fluff of the agitator 150; when the agitator 150 rotates in the second direction, the agitator cleaning member 190 can straighten the fluff of the agitator 150.

[0114] The first direction is the rotation direction of the agitator 150 of the surface cleaning device when performing a cleaning operation; the second direction is the opposite direction of the first direction; Figure 7 Taking the direction in as an example, the first direction is clockwise; the second direction is counterclockwise.

[0115] In the present disclosure, preferably, the curvature diameter of the continuous smooth inner surface is equal to or slightly smaller than the outer diameter of the agitator 150 , that is, equal to or slightly smaller than the above-mentioned first diameter and larger than the second diameter.

[0116] like Figure 8 As shown, the water outlet 112 is provided in plurality. Preferably, the water outlet 112 is distributed in a substantially transverse direction on the continuous and smooth inner surface, and the water outlet 112 is close to the first edge. Thus, when the surface to be cleaned is cleaned by the surface cleaning device, the cleaning liquid provided to the agitator 150 by the water outlet 112 has more time to become uniform, so that the cleaning liquid can be dispersed more evenly on the agitator 150.

[0117] In a preferred embodiment, the agitator cleaning member 190 is located below the first edge 1411 of the cover body 141 and is arranged close to the first edge 1411 .

[0118] Figure 9 It is a schematic diagram of the coordination relationship between the cleaning portion and the agitator according to one embodiment of the present disclosure.

[0119] Therefore, if Figure 9 As shown, when the agitator 150 rotates in the first direction, the fluff on the outside of the agitator 150 is wetted, that is, in a moist state. The wet fluff on the agitator 150 is smoothed by the agitator cleaning member 190, that is, at least a portion of the fluff extends along the circumference of the agitator 150. At this time, the fluff on the agitator 150 will not frictionally interfere with the continuous and smooth inner surface of the cover 141. Correspondingly, when the agitator 150 rotates in the second direction, the agitator cleaning member 190 can straighten the fluff, that is, extend along the radial direction of the agitator 150. At this time, the agitator 150 will frictionally interfere with the continuous and smooth inner surface of the cover 141, thereby carrying the dirt accumulated on the continuous and smooth inner surface of the cover 141 to the position of the suction nozzle 122, and the dirt is recovered by the suction nozzle 122 into the recovery tank 123.

[0120] Figure 10 It is a schematic structural diagram of an agitator decontamination component according to one embodiment of the present disclosure. Figure 11 yes Figure 10 Schematic diagram of the enlarged structure of part A.

[0121] In a preferred embodiment, Figure 10 and Figure 11 As shown, the agitator cleaning member 190 includes an interference portion, the outer edge of which is substantially flush with the first edge 1411; Figure 8 As shown, the outer edge of the interference portion, that is, the portion of the interference portion away from the first edge 1411, is the lower edge of the interference portion.

[0122] like Figure 11 As shown, the interference portion includes a plurality of serrations 191, and intervals are provided between adjacent serrations 191, so that the fluff of the agitator 150 can be combed and decontaminated by the serrations 191, making the fluff of the agitator 150 cleaner and regularly arranged, thereby having a better cleaning effect.

[0123] Figure 12 is a schematic structural diagram of a fluid dispenser 116 according to one embodiment of the present disclosure. Figure 13 It is a structural schematic diagram of a cover according to one embodiment of the present disclosure.

[0124] like Figure 12 and Figure 13 As shown, the fluid distribution system also includes a fluid distributor 116, and the cover body 141 also includes a receiving interface 1413 docked with the distribution port 1161 of the fluid distributor 116, and the cleaning liquid distributed by the fluid distributor 116 is sprayed out from the water outlet through the receiving interface 1413 of the cover body 141.

[0125] In a preferred embodiment, the distribution port 1161 is formed as a half-tube structure, and accordingly, the receiving interface 1413 of the cover body 141 is also formed as a half-tube structure. When the cover body 141 and the fluid distributor 116 are matched, a clean liquid distribution flow channel can be formed, wherein the clean liquid distribution flow channel can be connected to all water outlets, and the position where the clean liquid enters the clean liquid distribution flow channel is taken as the starting point, and the starting point to each water outlet 112 has a flow path of approximately the same length, so that each water outlet 112 can be distributed with an equal flow of clean liquid.

[0126] Figure 14 It is a schematic cross-sectional structural diagram of a cover body according to one embodiment of the present disclosure.

[0127] like Figure 14As shown, a first flow guiding channel L1 and a second flow guiding channel L2 are provided between the receiving interface 1413 and the water outlet 112. The first flow guiding channel L1 is larger than the second flow guiding channel L2. Preferably, the cross-sectional area of ​​the first flow guiding channel L1 is larger than the cross-sectional area of ​​the second flow guiding channel L2. Furthermore, when both the first flow guiding channel L1 and the second flow guiding channel L2 are cylindrical channels, the diameter of the first flow guiding channel L1 is larger than the diameter of the second flow guiding channel L2.

[0128] Moreover, when the second flow channel L2 is formed as a tapered flow channel, such as a circular conical flow channel, the diameter of the first flow channel L1 is larger than the maximum diameter of the second flow channel L2, so that the cleaning liquid can flow smoothly in the first flow channel L1 and the second flow channel L2.

[0129] In the present disclosure, the end point of the second flow channel L2 is formed as the water outlet 112.
