[0030] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0031] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0033] Figure 1 This is a schematic diagram of the structure of a surface cleaning system according to one embodiment of the present disclosure.

[0034] like Figure 1 As shown, the surface cleaning system disclosed herein may include a surface cleaning device 100 and a base station 200 for docking (connecting) the surface cleaning device 100. This surface cleaning system can provide users with an efficient and convenient cleaning solution. By combining the surface cleaning device 100 with the base station 200, it not only achieves the cleaning of the indoor environment, but also optimizes the maintenance and user experience of the surface cleaning device 100 through the auxiliary functions of the base station 200.

[0035] In one specific embodiment, the surface cleaning device 100 can be a stick vacuum cleaner, and thus, the surface cleaning system can be a stick vacuum cleaning system.

[0036] The surface cleaning device 100, as the execution component of the surface cleaning system, is responsible for sucking up and collecting dust, dirt, and other foreign objects from the surface to be cleaned. The base station 200 serves as its supporting facility, used for docking and storing the surface cleaning device 100. When the surface cleaning device 100 is docked at the base station 200, the base station 200 can charge the surface cleaning device 100. At this time, the surface cleaning device 100 can be set up roughly upright, that is, the surface cleaning device 100 is configured to be docked upright at the base station 200.

[0037] Figure 2 This is a schematic diagram of the structure of a cleaning head according to one embodiment of the present disclosure. Figure 3 This is a structural schematic diagram of the protrusion 170 according to one embodiment of the present disclosure. Figure 4 and Figure 5 This is a structural schematic diagram of the protrusion 170 from another angle according to one embodiment of the present disclosure.

[0038] like Figures 1 to 5As shown, the surface cleaning device 100 of this disclosure may include components such as a main body 110, an air suction pipe 120, a cleaning head 130, and a dust collection device 140. The main body 110 is connected to the dust collection device 140. The cleaning head 130 is detachably connected to the lower end of the air suction pipe 120, and the upper end of the air suction pipe 120 is detachably connected to the main body 110 and communicates with the dust collection device 140. Thus, a mixture of dirt and air on the surface to be cleaned can enter the air suction pipe 120 from the cleaning head 130 and then enter the dust collection device 140 through the air suction pipe 120. After gas-solid separation is completed in the dust collection device 140, the dirt is retained in the dust collection device 140, and the gas is discharged through an opening on the side of the main body 110.

[0039] Therefore, the surface cleaning device 100 disclosed herein is designed to be lightweight and flexible, suitable for use in various scenarios such as home and office.

[0040] Specifically, the main body 110 may include a vacuum source (not shown), which generates the suction force required to remove foreign objects from the surface to be cleaned. The vacuum source is the core power source of the surface cleaning device 100, and its performance directly affects the dust removal effect. It typically uses a high-efficiency brushless motor, which features low noise, high suction power, and long lifespan.

[0041] The main body 110 may include a handle 150 for the user to grip and operate the surface cleaning device 100. The user can hold the handle 150 and move the surface cleaning device 100 in the back-and-forth direction. The handle 150 is ergonomically designed, typically using non-slip materials and a streamlined shape to ensure a comfortable operating experience for the user even during prolonged use.

[0042] The main body 110 may include a suction nozzle 160, which is used to connect to the suction tube 120 or the cleaning head 130. The suction nozzle 160 is a key component of the airflow channel, and its internal structure is optimized to ensure that foreign objects can enter the dust collection device 140 smoothly and efficiently, avoiding blockage or suction loss.

[0043] The suction tube 120 can be detachably connected to the nozzle 160, thereby extending the cleaning range. Specifically, the user can choose whether to use the suction tube 120 according to actual cleaning needs. For example, when cleaning higher areas (such as the top of curtains or the ceiling), the suction tube 120 can extend the working range of the surface cleaning device 100, while when cleaning narrow spaces (such as sofa crevices), the nozzle 160 can be directly connected to the cleaning head 130, increasing operational flexibility.

[0044] Furthermore, the nozzle 160 can be configured to connect directly to the cleaning head 130 instead of the suction tube 120, or the nozzle 160 can be connected to other components, such as an auxiliary suction unit. This versatility in connection allows the surface cleaning device 100 to be compatible with a variety of cleaning attachments, such as crevice tools, soft brushes, or mite-removal tools, thereby expanding its functionality and meeting users' cleaning needs in different scenarios.

[0045] The suction tube 120 can be extended to have an extension axis extending in one direction. This extension axis is generally aligned with the overall longitudinal direction of the surface cleaning device 100. Therefore, users can increase cleaning convenience by connecting various components to the nozzle 160 according to the cleaning situation. For example, when cleaning large areas of flooring, users can choose a longer suction tube 120 and a wide-mouth floor brush combination, while when cleaning furniture surfaces, they can switch to a shorter tube and a soft-bristled brush to improve cleaning efficiency and precision.

[0046] The cleaning head 130 is used to move across the surface to be cleaned, and can be selectively configured as a floor brush or a bed brush to meet the cleaning requirements of different surfaces (such as floors, carpets, and mattresses). The cleaning head 130 of this disclosure can be implemented using solutions in the prior art, which will not be described in detail here.

[0047] The surface cleaning device 100 of this disclosure may further include a protrusion 170. In one specific embodiment, the protrusion 170 is formed projecting from the cleaning head 130. For example, the cleaning head 130 includes a connecting section 131 connected to the suction tube 120, and the protrusion 170 is formed rearwardly from the outer surface of the connecting section 131 when the connecting section 131 is arranged generally vertically. In another embodiment, the protrusion 170 of this disclosure may also be formed on the suction tube 120, and this disclosure does not limit the position of the protrusion 170.

[0048] When the surface cleaning device 100 is stored in the base station 200 with the main body 110 as the upper side, the cleaning head 130 as the lower side, and the main body 110 and the cleaning head 130 of the surface cleaning device 100 connected by the suction pipe 120, the protrusion 170 is located behind the cleaning head 130 of the surface cleaning device 100 and is used to lock the surface cleaning device 100 to the base station 200, and to keep at least a portion of the protrusion 170 bearing a portion of the reaction force of the total weight of the surface cleaning device 100.

[0049] Furthermore, since the cleaning head 130 can be placed on the base station 200, the supporting force provided by the base station 200 to the cleaning head 130 can also balance at least part of the weight of the surface cleaning device 100. In other words, at least a portion of the cleaning head 130 bears a portion of the reaction force of the total weight of the surface cleaning device 100.

[0050] Therefore, the surface cleaning device 100 disclosed herein can be stably supported by the base station 200 without tipping over.

[0051] The structure of the protrusion 170 is described below with reference to the accompanying drawings.

[0052] Specifically, the protrusion 170 of this disclosure includes an extension 171 protruding from the outer surface of the cleaning head 130 and an engaging portion 172 extending outwardly from the edge of the free end of the extension 171. Figure 5 In the structure shown, the portion of the protrusion 170 near the cleaning head 130, i.e., the extension 171, has an engagement portion 172 formed on its free end away from the cleaning head 130. Specifically, the engagement portion 172 is an outer flange on the free end of the extension 171.

[0053] The lower end of the extension 171 is provided with a limiting protrusion 173, which is used to limit the position of the surface cleaning device in the circumferential direction. That is, the limiting protrusion 173 can prevent the surface cleaning device from rotating in the circumferential direction after it is docked at the base station 200.

[0054] In the direction of gravity in which the surface cleaning device 100 is housed in the base station 200, the thickness of the engaging portion 172 gradually increases. As a result, the engaging portion 172 of this disclosure can be formed into a shape that mates with the groove of the base station 200, thereby enabling the surface cleaning device 100 to be stably docked at the base station.

[0055] The structure of base station 200 will be described in detail below with reference to the accompanying drawings.

[0056] Figure 6 This is a schematic diagram of the structure of a base station according to one embodiment of the present disclosure. Figure 7 This is a structural schematic diagram of a base station according to one embodiment of the present disclosure from another angle. Figure 8 This is a schematic diagram of the structure of the recess 240 of a base station according to one embodiment of the present disclosure. Figure 9 and Figure 10 This is a structural schematic diagram of the recess 240 of a base station according to one embodiment of the present disclosure from another angle.

[0057] like Figures 6 to 10 As shown, the base station 200 of this disclosure includes a base portion 210, a support portion 220, and a housing portion 230.

[0058] The base portion 210 of this disclosure is formed in a generally square shape and has certain dimensions so that when the surface cleaning equipment is parked on the base station 200, the surface cleaning equipment 100 will not tip over or cause other problems.

[0059] The support column 220 is formed vertically upward from the base 210. This vertical upward formation does not mean that the support column 220 must be vertically aligned when the base 210 is mounted on a generally horizontal surface, but rather that the support column 220 has a certain height. Figure 6 In the implementation shown, the support portion 220 can also be set at an angle, that is, the support portion 220 is not set perpendicular to the base portion 210.

[0060] The base portion 210 has a placement surface for placing the cleaning head 130 of the surface cleaning device 100; this placement surface is at least a portion of the upper surface of the base portion 210. For example, with the support portion 220 as the boundary, the placement surface is located on the front side of the support portion 220, and the storage portion 230 is located on the rear side of the support portion 220.

[0061] The storage section 230 is formed in the base section 210 and located behind the support section 220. The storage section 230 is configured to hold a replaceable cleaning head 130 of the surface cleaning device 100. Figure 1 As shown, these replaceable parts may include components such as roller brushes, connectors, and cleaning tools, and this disclosure is not limiting in this regard.

[0062] Specifically, the receiving portion 230 can be a plurality of receiving holes formed on the base portion 210, the axis of which can be in a generally vertical direction, and the plurality of receiving holes can be arranged on the same straight line.

[0063] like Figure 8 As shown, the upper free end of the support portion 220 of this disclosure has a recess 240 that is recessed downward in the vertical direction. The recess 240 is configured to engage with the protrusion 170 on the surface cleaning device 100 to lock the surface cleaning device 100 to the base station 200.

[0064] For example, when the surface cleaning device 100 is stored in the base station 200 with the main body 110 as the upper side, the cleaning head 130 as the lower side, and the main body 110 and the cleaning head 130 of the surface cleaning device 100 connected by the suction pipe 120, the recess 240 is located behind the cleaning head 130 of the surface cleaning device 100 and locks the surface cleaning device 100 to the base station 200, and at least a portion of the recess 240 bears a portion of the total weight of the surface cleaning device 100.

[0065] In other words, the recess 240 of this disclosure can support the surface cleaning device 100 by applying a supporting force to the protrusion 170. Moreover, since the recess 240 has a certain depth, the recess 240 of this disclosure can also stably hold the surface cleaning device, so that the surface cleaning device will not detach from the recess 240 and tip over.

[0066] Therefore, when using the surface cleaning system of this disclosure, the user can easily lift the surface cleaning device, align the protrusion 170 and the recess 240, and then place the surface cleaning device on the base station 200, resulting in a better user experience. Furthermore, the base station 200 of this disclosure is small in size and environmentally friendly.

[0067] In this disclosure, the portion where the recess 240 and the protrusion 170 engage is located closer to the front of the base portion 210 than the receiving portion 230. In other words, this engaging portion can be positioned close to the center of the base station 200, thereby making it easier for the surface cleaning device 100 to be supported by the base station 200. In this case, the projection of the surface cleaning device 100 on the base station will be completely or at least mostly located inside the base station 200, thus effectively preventing problems such as the surface cleaning device tipping over.

[0068] In this disclosure, the upper end of the support portion 220 has a guide portion 250 that slopes towards the bottom of the recess 240. When the protrusion 170 engages with the recess 240, the guide portion 250 guides the engagement, thereby making it easier to place the surface cleaning device 100 of this disclosure onto the base station 200. Specifically, the user does not need to completely align the protrusion 170 and the recess 240, but can simply align the protrusion 170 with the upper end of the entire support portion 220. In this case, under the guidance of the guide portion 250, the protrusion 170 can be guided into the recess 240 and stably held within the recess 240.

[0069] In one specific embodiment, the guide portion 250 includes a first segment 251 located at the upper part and a second segment 252 located at the lower part. The slope of the first segment 251 is smaller than that of the second segment 252. Therefore, the first segment 251 can initially guide the protrusion 170. Moreover, when the protrusion 170 is guided by the first segment 251, because the first segment 251 has a smaller slope, the protrusion 170 has a smaller movement speed relative to the first segment 251, making it easier for the user to control the surface cleaning device. In addition, because the second segment 252 has a larger slope, when the protrusion 170 is guided by the second segment 252, the protrusion 170 can enter the recess 240 more quickly.

[0070] The recess 240 disclosed herein includes a first receiving wall 241 connected to the guide portion 250, and a first mating portion 242 formed on the surface of the first receiving wall 241 and extending in the gravity direction of the surface cleaning device 100 housed in the base station 200. The first receiving wall 241 may be the rear sidewall of the recess 240. The recess 240 also includes a front sidewall with an opening sized to facilitate the passage of the protrusion 170, thereby allowing the protrusion 170 to be smoothly inserted into the recess 240.

[0071] The first mating part 242 includes at least one first protruding rib, which extends from the guide part 250 to the bottom of the recess 240. Thus, by providing the first protruding rib, the strength of the support part 220 can be improved, and the process of inserting the protrusion 170 into the recess 240 can also be guided.

[0072] In a preferred embodiment, the height of the ribs extending outward from the surface of the first receiving wall 241 gradually increases in the direction of gravity in which the surface cleaning device 100 is housed in the base station 200. As a result, the ribs 170 can be gradually clamped and positioned as they are inserted into the recess 240 from top to bottom, so that the surface cleaning device does not change position relative to the base station.

[0073] Similarly, the recess 240 includes two opposing second receiving walls 243 connected to the guide portion 250, and at least one second mating portion (which has the same / similar structure to the first mating portion and is not shown in the figure) disposed adjacent to at least one second receiving wall 243 and extending in the gravity direction of the surface cleaning device 100 housed in the base station 200. The second receiving wall 243 of this disclosure can be a left side wall and a right side wall, thereby forming the side wall of the recess 240 together through the first receiving wall 241 and the second receiving wall 243.

[0074] The second mating part includes at least one second rib, which extends from the guide part 250 to the bottom of the recess 240. Thus, by providing the second rib, the strength of the support part 220 can be improved, and the process of inserting the protrusion 170 into the recess 240 can also be guided.

[0075] In addition, similar to the structure of the first rib, the second rib of this disclosure gradually increases in height from the surface of the first receiving wall 241 in the direction of gravity in which the surface cleaning device 100 is housed in the base station 200.

[0076] A limiting groove 245 can be formed on the bottom surface of the recess 240 of this disclosure, and the limiting protrusion 173 can cooperate with the limiting groove 245 to play a limiting role. Specifically, when the surface cleaning equipment is parked at the base station, the limiting protrusion 173 can enter the limiting groove 245, thereby preventing the surface cleaning equipment from changing position relative to the base station in the circumferential direction.

[0077] In general, in the surface cleaning system disclosed herein, when the main body 110 of the surface cleaning device 100 is placed in the base station 200 with the cleaning head 130 as the lower side and the main body 110 and the cleaning head 130 of the surface cleaning device 100 connected by the suction pipe 120, the recess 240 is located behind the cleaning head 130 of the surface cleaning device 100 and locks the surface cleaning device 100 onto the base station 200, and the recess 240 and the placement surface jointly bear the total weight of the surface cleaning device 100.
