[0024] Selectable embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0025] The maintenance station system for surface cleaning equipment comprises a main station (later also called a station) and an accessory bracket. The main station is used to support the surface cleaning equipment, and the accessory bracket is used to support the accessories for the surface cleaning equipment. The main station and the accessory bracket are separable, and the key to achieving a good user experience is how rationally and easily the user can set the positional relationship between the main station and the accessory bracket according to the spatial location during use.

[0026] Embodiments of the present invention provide a maintenance station system for surface cleaning equipment, comprising a main station configured to support the surface cleaning equipment and an accessory bracket configured to support accessories for the surface cleaning equipment, wherein the main station includes a tray portion having a first snap coupling structure and a support portion located on one side of the tray portion, where the first snap coupling structure is located on the side of the tray portion not facing the support portion, and the accessory bracket includes a second snap coupling structure provided on one side of the accessory bracket and configured to snap-couple with the first snap coupling structure to connect the accessory bracket to one side of the main station.

[0027] The surface cleaning equipment maintenance station system provided in the embodiment of the present invention features a first snap coupling structure on three sides of the main station, allowing the accessory bracket to be attached to any side of the main station via the first snap coupling structure. The accessory bracket can be attached to any one of the three positions according to the actual usage needs, and the user can flexibly install the main station and accessory bracket according to their own usage needs and spatial environment, thereby improving space utilization and user experience.

[0028] Specifically, embodiments of the present invention provide a maintenance station system for surface cleaning equipment. As an example, Figure 1 is a schematic diagram of the overall structure of a maintenance station system in several embodiments of the present invention. Figure 2 is a schematic diagram of the overall structure of a main station in several embodiments of the present invention. Figure 3 is a schematic diagram of the bottom structure of a main station in several embodiments of the present invention. Figure 4 is a schematic diagram of an enlarged view of part A of the main station in several embodiments of the present invention. Figure 5 is a schematic diagram of the overall structure of an accessory bracket in several embodiments of the present invention. Figure 6 is a schematic diagram of an enlarged view of part B of the accessory bracket in several embodiments of the present invention.

[0029] To more clearly explain the behavior of the self-cleaning maintenance station, the following directions are defined as shown in Figure 2, and the main station is calibrated by three mutually perpendicular axes: the horizontal axis Y, the longitudinal axis X, and the central vertical axis Z. The direction opposite to the arrow on the longitudinal axis X is denoted as "rear," and the direction along the arrow on the longitudinal axis X is denoted as "forward." The horizontal axis Y is essentially the direction along the width of the main station, the direction along the arrow on the horizontal axis Y is the "left side" of the main station, and the direction opposite to the arrow on the horizontal axis Y is the "right side" of the main station. The vertical axis Z is the direction extending upward along the bottom surface of the main station, the direction along the arrow on the vertical axis Z is the "upper side" of the main station, and the direction opposite to the arrow on the vertical axis Z is the "lower side" of the main station.

[0030] Specifically, as shown in Figures 1, 2, and 5, an embodiment of the present invention is a maintenance station system for surface cleaning equipment, the maintenance station system comprising a main station 100, the main station 100 configured to support surface cleaning equipment, the surface cleaning equipment including, for example, a handheld floor scrubber, a mop, a vacuum cleaner, etc., the main station 100 includes a tray section 110, the tray section 110 has a first snap coupling structure 111, the main station 100 further includes a support section 120, the support section 120 is located on one side of the tray section 110, and here, the first snap The snap coupling structure 111 is located on the side of the tray section 110 that does not face the support section 120, and the maintenance station system further comprises an accessory bracket 200, which is configured to support accessories for surface cleaning equipment, and the accessory bracket 200 has a second snap coupling structure 211, which is provided on one side of the accessory bracket 200, and the second snap coupling structure 211 is configured to snap with the first snap coupling structure 111 to connect the accessory bracket 200 to one side of the main station 100.

[0031] In some embodiments, the projection of the tray portion 110 onto the ground has a substantially circular, elliptical, rectangular, square, polygonal, or other shape, and is not limited thereto. In this embodiment, a rectangle is used as an example, and as shown in Figure 2, when the projection of the tray portion 110 onto the ground is substantially rectangular, the first snap coupling structure 111 is located on any side of the tray portion 110 adjacent to the support portion 120. For example, if there is one first snap coupling structure 111, the first snap coupling structure 111 is located on the left or right side of the tray portion 110, or on the side where the support portion 120 is located. If there are two first snap coupling structures 111, the two first snap coupling structures 111 are located on each side. If the tray section 110 is located on any two of the left, right, and support sections 120 sides, and includes three first snap-connection structures 111, the three first snap-connection structures 111 are located on the left, right, and support sections 120 sides of the tray section 110, respectively, that is, the first snap-connection structures 111 do not need to be located on the side facing the support section 120, and the first snap-connection structures 111 may be located on any one, two, or three of the remaining three sides of the tray section 110. Since surface cleaning equipment needs to be removed and placed on the side of the tray section 110 facing the support section 120, providing the first snap-connection structures and placing the accessory bracket on this side may affect the removal and placement of surface cleaning equipment. Furthermore, since dry airflow may be blown out from this side, placing the accessory bracket on this side may affect the provision of air paths for the tray section.

[0032] In some embodiments, as shown in Figure 3, there are three first snap coupling structures 111, located on both sides adjacent to the support portion 120 of the tray portion 110 and on the side where the support portion 120 is located. Since the first snap coupling structures are provided at three positions on the tray portion, the accessory bracket can be provided on any side of the main station via the first snap coupling structures, thereby allowing the accessory bracket to be attached to any of the three positions according to actual usage needs. As a result, users can install the main station and accessory bracket as flexibly as possible according to their usage needs and spatial environment, improving space utilization and user experience.

[0033] In some embodiments, as shown in Figures 3 and 4, the first snap-connection structure 111 includes a recess 1111 which is formed from one side edge of the tray portion 110 toward the center of the tray portion 110, and the first snap-connection structure 111 further includes a first snap-connection arrangement 1112 which is formed in a predetermined shape within the recess 1111. The specific shape of the first snap-connection arrangement 1112 is not limited and may be, for example, a wavy structure, a long stripe structure, a short stripe structure, etc., and the first snap-connection arrangement 1112 has at least one open position to facilitate fitting and snap-connecting with the second snap-connection structure.

[0034] In some embodiments, as shown in Figure 4, the recessed portion 1111 is a semi-enclosed structure surrounded by a first side wall extending vertically. The first snap-connection arrangement 1112 is formed by a plurality of second side walls extending vertically. The side walls of the recessed portion 1111 and the first snap-connection arrangement 1112 extend along the vertical direction, facilitating fitting and snap-connection with the second snap-connection structure.

[0035] In some embodiments, as shown in Figure 5, the second snap coupling structure 211 is formed protruding along one side edge of the accessory bracket 200, and the second snap coupling structure 211 has a second snap coupling arrangement, which fits with the first snap coupling arrangement 1112 to achieve a snap coupling. For example, the second snap coupling arrangement and the first snap coupling arrangement 1112 are male-female snap couplings, i.e., the side walls of the second snap coupling arrangement extending vertically are just in the open positions of the first snap coupling arrangement, so that after the second snap coupling structure is snap-coupled with the first snap coupling structure, the second snap coupling structure is housed within the first snap coupling structure, for example, the second snap coupling structure may fill all the open positions of the first snap coupling structure, or it may fill only some of the open positions of the first snap coupling structure. Since the second snap coupling arrangement and the first snap coupling arrangement are male-female snap couplings, the main station 100 and the accessory bracket 200 are more securely connected and less likely to detach and tip over. During use, the tray section 110 is slightly lifted, and the second snap coupling structure 211 of the accessory bracket 200 extends to the position of the first snap coupling structure 111 below the tray section 110. By pushing down the tray section 110, the second snap coupling arrangement snaps into the first snap coupling arrangement, and the accessory bracket 200 is connected to one side of the main station 100. Depending on the spatial orientation of the main station 100's location, the user can connect the accessory bracket 200 to any side of the main station 100.

[0036] In some embodiments, as shown in Figure 5, the accessory bracket 200 further includes a storage tray 210 configured to store accessories for surface cleaning equipment, such as dust collection barrels, roller brushes, brush heads, etc., and the accessory bracket 200 further includes a storage rod 220 located on one side of the storage tray 210, and the storage rod 220 configured to store brush heads having extension rods, where the second snap coupling structure 211 is located on the side of the storage tray 210 opposite to the storage rod 220. Since the external shape of the second snap coupling structure 211 corresponds to the shape of the recess 1111 of the first snap coupling structure 111, after the second snap coupling structure 211 is snap-coupled with the first snap coupling structure 111, the second snap coupling structure 211 is completely housed within the recess 1111 of the first snap coupling structure 111. As a result, one side edge of the storage tray 210 substantially abuts against one side edge of the tray portion 110, further ensuring stability after the accessory bracket 200 is connected to the main station 100, and ensuring orderliness between the accessory bracket 200 and the main station 100.

[0037] In some embodiments, as shown in Figure 6, the second snap coupling structure 211 has a second snap coupling arrangement which includes two edge sidewalls 2111 extending outward along the side wall of the storage tray 210, two central sidewalls 2112 located between the two edge sidewalls 2111, and a lateral sidewall 2113 connected to the ends of the two central sidewalls 2112, and the rigidity of the second snap coupling arrangement and the robustness of the connection between the accessory bracket 200 and the main station 100 are enhanced by the edge sidewalls 2111, the central sidewalls 2112 and the lateral sidewalls 2113.

[0038] The surface cleaning equipment maintenance station system provided in the embodiment of the present invention comprises a main station having a first snap coupling structure and an accessory bracket having a second snap coupling structure. By providing the first snap coupling structure on three sides of the main station, the accessory bracket can be attached to any side of the main station via the first snap coupling structure, and the accessory bracket can be attached to any one of the three positions according to the actual usage needs. This allows the user to install the main station and accessory bracket as flexibly as possible according to their usage needs and spatial environment, thereby improving space utilization and user experience.

[0039] Accessory brackets can store accessories for multiple surface cleaning devices, but the storage structure within the accessory bracket typically employs a fixed storage method, meaning that one storage structure can only store accessories in one orientation. Users are not allowed to change the storage orientation of accessories via the fixed storage structure according to their space needs, which affects the user experience.

[0040] This embodiment provides an accessory bracket comprising a storage tray configured to store accessories for a surface cleaning device, and a storage rod located on one side of the storage tray and configured to store a brush head having an extension rod, wherein the storage rod has a first storage position, a second storage position and a third storage position, where the first and second storage positions realize a first storage position for the brush head, and the first and third storage positions realize a second storage position for the brush head.

[0041] The accessory bracket provided in this embodiment has three storage positions, allowing the user to store the brush head with extension rod in two ways as needed. The first storage combination holds the brush head and extension rod in a substantially vertical position, with a portion of the brush head lying flat on the ground. The second storage combination positions the brush head and extension rod in a substantially coplanar position, with the bottom surface of the brush head substantially perpendicular to the ground. Compared to the first storage combination, this method occupies less space and offers more flexible storage. According to this invention, the user can adopt one of the two storage methods according to their own usage needs and spatial environment, thereby improving space utilization and user experience.

[0042] Specifically, the present invention will be described in detail by the following embodiments, referring to Figures 7 to 9, where Figure 7 is a schematic diagram of the structure of the accessory bracket in the first storage position. Figure 8 is a schematic diagram of the structure of the accessory bracket in the second storage position. Figure 9 is a schematic diagram of the structure showing each storage position of the accessory bracket in detail in several embodiments of the present invention.

[0043] As shown in Figure 7, an embodiment of the present invention provides an accessory bracket 200, which includes a storage tray 210 configured to store accessories for a surface cleaning machine, such as a dust collection barrel, roller brush, brush head, etc. The accessory bracket 200 further includes a storage rod 220, which is located on one side of the storage tray 210 and extends substantially perpendicular to the direction of the storage tray 210, and is configured to store a brush head 300 having an extension rod, the storage rod 220 having a first storage position 221, a second storage position 222 and a third storage position 223, where the first storage position 221 and the second storage position 222 cooperate to achieve a first storage position of the brush head 300, and the first storage position 221 and the third storage position 223 cooperate to achieve a second storage position of the brush head 300. In the first storage position, the first storage position 221 is engaged with the extension rod 310, and the second storage position 222 is in contact with the adapter portion 320 of the brush head. In the second storage position, the first storage position 221 is engaged with the extension rod 310, and the third storage position 223 is in contact with the bottom surface 330 of the brush head. As shown in Figure 7, the first storage position holds the brush head 300 and the extension rod 310 vertically, with a portion of the brush head lying flat on the ground. As shown in Figure 8, in the second storage position, the brush head 300 and the extension rod 310 are substantially on the same plane, and the bottom surface of the brush head is substantially perpendicular to the ground. For example, the angle between the brush head 300 and the extension rod 310 can be set from 150 to 180 degrees. Compared to the first storage combination method, it occupies less space and offers more flexible storage.

[0044] In some embodiments, as shown in Figure 7, the first storage position 221 is located on the side of the second storage position 222 that is away from the storage tray 210, and the third storage position 223 is located on the side of the second storage position 222 that is closer to the storage tray 210. That is, the first storage position 221, the second storage position 222, and the third storage position 223 are spaced apart from top to bottom along the storage rod 220, and they work together to facilitate the realization of the two storage positions of the roller brush.

[0045] In some embodiments, as shown in Figure 7, the first storage position 221, the second storage position 222, and the third storage position 223 are all located away from the storage tray of the storage rod 220, thereby facilitating the storage of the brush head 300 with the extension rod.

[0046] In some embodiments, as shown in Figure 9, the first storage position 221 extends away from the storage tray 210 along a direction substantially perpendicular to the storage rod 220, and the first storage position 221 includes a storage arm 2211 extending away from the storage tray 210 along a direction substantially perpendicular to the storage rod 220, and a first arc-shaped storage structure 2212 is provided at the end of the storage arm 2211, and the first arc-shaped storage structure 2212 is configured to house the extension rod 310 of the brush head. The storage arm 2211 is made of plastic or metal material, and the end of the storage arm 2211 is slightly elastic so that the extension rod 310 can be easily snapped into the first arc-shaped storage structure 2212. Optionally, an anti-slip structure is provided at the inner edge position of the first arc-shaped storage structure 2212 to more stably snap in the extension rod 310 of the brush head.

[0047] In some embodiments, as shown in Figure 9, the second storage position 222 extends away from the storage tray 210 along a direction substantially perpendicular to the storage rod 220, and a second arc-shaped storage structure is provided at the end of the second storage position 222, which is configured to house the adapter portion of the brush head, the adapter portion 320 being used to connect the extension rod 310 and the brush head 300, the diameter of the adapter portion being larger than the diameter of the extension rod, and when stored in the first storage position 221 and the second storage position 222, the first storage position 221 snaps the extension rod 310 together, and the second storage position 222 contacts the adapter portion 320 via the second arc-shaped storage structure, thereby achieving storage of the brush head 300 in a first storage position. Selectively, the second storage position 222 consists of a horizontally extending storage plate 2221 and a support plate 2222 supported below the storage plate 2221, with the end of the storage plate 2221 having a second arc-shaped storage structure.

[0048] In some embodiments, as shown in Figure 9, the third storage position 223 extends away from the storage tray 210 along a direction substantially perpendicular to the storage rod 220, and the end plane of the third storage position 223 is not parallel to the axis of the storage rod 220. For example, the end plane of the third storage position 223 is slightly inclined upward to more easily support the bottom surface of the brush head in an upright position. Alternatively, for example, the end of the third storage position 223 may have an inclined surface, which is not parallel to the axis of the storage rod 220, and an anti-slip structure may be optionally provided on the inclined surface.

[0049] In some embodiments, as shown in Figure 9, the third storage position 223 includes a support cavity 2233, which is surrounded by a side wall 2231 substantially perpendicular to the storage rod, and a reinforcing rib 2232 is provided within the support cavity 2233, which is connected to the opposing side wall of the cavity. The end face of the side wall 2231 constitutes the inclined surface, which is not parallel to the axis of the storage rod 220, i.e., the third storage position 223 supports the bottom surface of the brush head at a force application angle that is slightly inclined upward, and optionally, the end face of the side wall 2231 has an anti-slip structure. The reinforcing rib 2232 is used to reinforce the degree of stress applied to the third storage position 223, and its end face does not extend beyond the plane formed by the end face of the side wall 2231. When storing in the first storage position 221 and the third storage position 223, the extension rod 310 is snap-connected in the first storage position 221, and the third storage position 223 contacts the bottom surface 330 of the support brush head via an inclined end face, preventing the bottom surface 330 that supports the brush head from sliding down, thereby enabling storage of the brush head 300 in the second storage position.

[0050] An embodiment of the present invention provides a maintenance station system comprising a main station as described in the above embodiment and an accessory bracket as described in any embodiment.

[0051] The accessory bracket provided in this embodiment has three storage positions, which allow the user to store the brush head with the extension rod in two ways as needed. The first storage combination holds the brush head and extension rod in a substantially vertical position, with the brush head portion lying flat on the ground. The second storage combination lies substantially on the same plane as the brush head and extension rod, with the bottom surface of the brush head substantially perpendicular to the ground. Compared to the first storage combination , this method occupies less space and offers more flexible storage. According to this invention, the user can adopt one of the two storage methods according to their own usage needs and spatial environment, thereby improving space utilization and user experience.

[0052] A station (i.e., the main station described in the above embodiment) typically includes heating devices such as multiple circuit boards. If a special heat dissipation structure is employed for heat dissipation, it not only increases the cost and the overall structure of the station but can also affect the layout of internal components. Therefore, it is necessary to rationally arrange the internal structure of the station to enhance its own heat dissipation effect.

[0053] In an embodiment of the present invention, the station (i.e., the main station described above) is configured to support a surface cleaning device and includes a housing having an air intake and an air outlet, a fan provided within the housing and having an air inlet and an air outlet, and a cooling device provided in the airflow path between the air intake of the housing and the air inlet of the fan, wherein the heat of the cooling device is removed by the airflow.

[0054] An embodiment of the present invention provides a station equipped with a fan, and as the airflow enters through the fan's air intake and flows to the air outlet, it may pass through gaps inside the housing. In particular, when the airflow passes through the gap between the two mainboards, it can remove the heat released when the two mainboards are operating, thereby ensuring a good working environment for the mainboards.

[0055] Specifically, the present invention will be described in detail by the following embodiments, referring to Figures 10 to 13, where Figure 10 is a schematic diagram of the cross-sectional structure of a station in several embodiments of the present invention. Figure 11 is a schematic diagram of a localized cross-sectional structure of a station in several embodiments of the present invention. Figure 12 is a schematic diagram of the rear local structure of a station in several embodiments of the present invention. Figure 13 is a schematic diagram of the local three-dimensional structure of a station in several embodiments of the present invention.

[0056] As shown in Figure 10, an embodiment of the present invention provides a station 100 configured to support and maintain surface cleaning equipment, the surface cleaning equipment including, for example, a handheld floor scrubber, a mop, a vacuum cleaner, etc., the station 100 includes a tray section 110 and a support section 120, the support section 120 is located on one side of the tray section 110, the support section 121 includes a housing 121, the housing 121 has an air intake 1211 and an air outlet 1212, the air intake 1211 is located on the back of the housing 121 and the air outlet 1212 is located on the underside of the housing 121, the support section 120 further includes a fan 122, the fan 122 is located inside the housing 121 and the fan 122 has an air inlet 1221 and The support unit 120 has an air outlet 1222, which causes airflow when the fan 122 rotates, and the airflow enters from the air inlet 1221 and exits from the air outlet 1222. The support unit 120 further includes a device to be cooled 123, which includes a first device to be cooled 1231 (e.g., a first circuit board) and a second device to be cooled 1232 (e.g., a second circuit board). A shell is provided on the outside of the first device to be cooled 1231 and the second heat dissipation device 1232 to prevent dust and water vapor from entering the shell. The device to be cooled 123 is located in the airflow path between the air intake 1211 of the housing 121 and the air inlet 1221 of the fan 122, and as the airflow moves, heat generated by the surface of the device to be cooled 123 is removed. The airflow path is shown by the arrow in Figure 10. This structure eliminates the need to add a separate heat dissipation structure, directly utilizing the airflow entering the fan (referred to as cold airflow before entering the fan) to remove heat from the device 123 to be cooled, thereby achieving the dual purpose of intake and heat dissipation.

[0057] In some embodiments, as shown in Figure 11, the airflow path has a first gap 1233 between the first cooling target device 1231 and the second cooling target device 1232. In some embodiments, the airflow path has a second gap 1234 between the surface of the cooling target device and the rear of the housing. In some embodiments, the airflow path has gaps on both sides and / or a bottom gap 1235 of the first cooling target device. That is, the cold airflow entering from the air inlet 1221 may pass through one or more of the first gap 1233, the second gap 1234, the gaps on both sides of the first cooling target device 1231, and the bottom gap 1235, and the number of gaps through which the air passes will vary depending on the fan output, and all of these gaps surround the first heat dissipation device 1231 so that the first heat dissipation device 1231 receives the best heat dissipation effect.

[0058] In some embodiments, as shown in Figure 12, the geometric center of the air intake 1211 is lower than the lower edge of the first gap 1233. In these embodiments, the air intake 1211 is circular, and its geometric center is circular; in the case of a rectangle, the geometric center is the intersection of the diagonals. The geometric center of the air intake 1211 is lower than the lower edge of the first gap 1233, and regardless of the size of the air intake 1211, the airflow is blown directly onto the surface of the first heat dissipation device 1231, and then the airflow spreads around the surface of the first heat dissipation device 1231 and flows along the surface of the first heat dissipation device 1231 toward one or more of the first gap 1233, the second gap 1234, the gaps on both sides of the first device to be cooled, and the bottom gap 1235, thereby ensuring the heat dissipation effect of the first device to be cooled 1231.

[0059] In some embodiments, as shown in Figure 13, the station 100 further includes a heating device 124, which is, for example, an electric heating element, and is located on one side of the air outlet of the fan 122. The airflow in the airflow path is discharged from the air outlet of the fan 122, then heated by the heating device 124, and flows out from the air outlet 1212 of the housing. As shown in Figure 10, the cold airflow passes through the fan and then enters the heating device 124, where it is heated to become a hot airflow. The hot airflow then passes through the hot air path 125 and is blown onto the roller brush to complete the drying of the roller brush. In this embodiment, the pre-heated airflow for drying at station 100 is used as a cooling airflow, and before this cooling airflow is heated, it is used for heat dissipation from the device to be cooled, completing its heat dissipation function. After the cooling airflow passes through the device to be cooled, it is preheated and then heated by the heating device 124 to become a drying airflow. During the cooling process, the airflow from the drying fan is reused for heat dissipation, eliminating the need for a separate heat dissipation fan and contributing to a reduction in the power consumption of the heating device 124. Similarly, air paths from fans for other functions within the equipment can also be reused; for example, the working airflow from a wastewater recovery fan can be reused for heat dissipation from the device to be cooled.

[0060] An embodiment of the present invention provides a station equipped with a fan, in which airflow is drawn in from the fan's air intake and, in the process of flowing to the air outlet, may pass through gaps inside the housing. In particular, when airflow passes through the gap between two mainboards, it can remove heat released when the two mainboards are operating, thereby ensuring a good working environment for the mainboards.

[0061] Finally, note that each example in this specification is described incrementally, each example focuses on its differences from the others, and identical or similar parts between examples may be referenced to one another.
