[0019] In order to make the purpose, solution and advantages of the present invention clearer, the present invention will be described in more detail below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, any other embodiments made by those skilled in the art without any inventive effort are also included in the protection scope of the present invention.

[0020] The terms used in the present invention are merely for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present invention and the appended claims, the singular forms "a," "the," and "the" are also intended to include the plural forms unless otherwise clearly indicated by the context, and "plurality" generally includes at least two.

[0021] It should be understood that the term "and / or" in this document is simply used to describe the relationship between related objects, and can represent the existence of three types of relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the symbol " / " in this document generally represents an "or" relationship between the related objects before and after it.

[0022] It should be understood that although the embodiments of the present invention may be described using terms such as first, second, and third, these are not limited to these terms. These terms are used merely to distinguish between the same types of items. For example, a first item may be referred to as a second item, and similarly, a second item may be referred to as a first item, without departing from the scope of the embodiments of the present invention.

[0023] It should be further explained that the terms "comprise," "include," "comprise," or any other synonyms are intended to cover a non-exclusive inclusion. Thus, a product or device having a series of elements includes not only those elements, but also other elements not expressly listed or inherent in such product or device. Unless further limited, an element qualified by the phrase "comprises a ..." does not preclude a product or device having said element from further including other identical elements.

[0024] The present invention provides a self-cleaning maintenance station for use with an automatic cleaning device, the self-cleaning maintenance station comprising a self-cleaning maintenance station body, the self-cleaning maintenance station body comprising a storage chamber configured to store at least a portion of the automatic cleaning device when the automatic cleaning device returns to the self-cleaning maintenance station, the body base configured to support at least a portion of the automatic cleaning device when the automatic cleaning device returns to the self-cleaning maintenance station, the body base having a cleaning tub facing the storage chamber, and the drying fan provided within the self-cleaning maintenance station body, located on a side of the storage chamber away from the body base, and configured to blow a dry airflow onto at least a portion of the cleaning tub to dry it.

[0025] In the self-cleaning maintenance station according to the present invention, the drying fan and / or gas heating device are located above the cleaning tub, thereby preventing water in the cleaning tub from splashing onto the drying fan and / or gas heating device, eliminating the need for waterproofing the drying fan and / or gas heating device. At least a portion of the drying air duct extends perpendicular to the base of the main body and blows dry air directly toward the cleaning tub, reducing wind noise and improving the user experience.

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0027] An embodiment of the present invention provides a self-cleaning maintenance station for use with an automatic cleaning device, which has the functions of charging the automatic cleaning device, collecting dust from the dust box of the automatic cleaning device, cleaning the mop of the automatic cleaning device, and drying the mop of the automatic cleaning device. For example, FIG. 1 is a schematic diagram of the overall structure of a self-cleaning maintenance station implemented according to the present invention.

[0028] To more clearly describe the behavior of the self-cleaning maintenance station, the following directions are defined. That is, the self-cleaning maintenance station can be oriented along three mutually perpendicular axes: a horizontal axis Y, a front-to-rear axis X, and a central vertical axis Z. The direction opposite to the direction along the arrow of the front-to-rear axis X, i.e., the direction in which the self-cleaning device enters the self-cleaning maintenance station, is labeled the "rear direction," and the direction along the arrow of the front-to-rear axis X, i.e., the direction in which the self-cleaning device leaves the self-cleaning maintenance station, is labeled the "forward direction." The horizontal axis Y is a direction substantially along the width of the self-cleaning maintenance station body. The vertical axis Z is a direction extending upward from the bottom surface of the self-cleaning maintenance station.

[0029] As shown in FIGS. 1 and 2 , the self-cleaning maintenance station includes a self-cleaning maintenance station main body 2000 and a self-cleaning maintenance station base plate 1000. The self-cleaning maintenance station main body 2000 includes a dust collection tank 3000, a purified water tank 4000, and a wastewater tank 5000, which are arranged adjacent to each other in sequence. The dust collection tank 3000 collects dust from the automatic cleaning device. The automatic cleaning device may be, for example, a vacuum cleaner / wiper integrated unit. After completing a cleaning operation, the automatic cleaning device may return to the self-cleaning maintenance station to perform a dust collection operation. Dust collected in the dust box of the automatic cleaning device may be collected in the dust collection tank 3000 during the dust collection operation. In this way, the user does not need to frequently clean the dust box of the automatic cleaning device, reducing the burden on the user.

[0030] The automatic cleaning appliance may return to the self-cleaning maintenance station during or after the cleaning process to perform a cleaning operation on its wet cleaning module. The clean water tank 4000 provides the automatic cleaning appliance with clean water to clean the wet cleaning module and contains cleaning water for, for example, a mop, and the dirty water tank 5000 collects dirty water after cleaning is completed.

[0031] The self-cleaning maintenance station main body 2000 comprises a storage chamber 7000 and a main body base 6000. The storage chamber 7000 is configured to store at least a portion of the automatic cleaning equipment when the automatic cleaning equipment is returned to the self-cleaning maintenance station. The main body base 6000 is configured to support at least a portion of the automatic cleaning equipment when the automatic cleaning equipment is returned to the self-cleaning maintenance station. The main body base 6000 has a washing basin 6100 facing the storage chamber 7000. The washing basin 6100 stores at least a portion of the wet cleaning module of the automatic cleaning equipment so that a mop of the automatic cleaning equipment can be operated for cleaning within the washing basin 6100.

[0032] The self-cleaning maintenance station bottom plate 1000 is detachably assembled to the self-cleaning maintenance station main body 2000. Specifically, the self-cleaning maintenance station bottom plate 1000 is detachably assembled to the main body base 6000. When the automatic cleaning device returns to the self-cleaning maintenance station, the self-cleaning maintenance station bottom plate 1000 supports part of the automatic cleaning device. The self-cleaning maintenance station bottom plate 1000 has a slanted top surface, which makes it easy for the automatic cleaning device to return to the self-cleaning maintenance station to perform various operations.

[0033] Specifically, when the automatic cleaning device returns to the self-cleaning maintenance station to perform a cleaning operation, it turns around and returns to the self-cleaning maintenance station, with at least a portion of the wet cleaning module located at the rear of the automatic cleaning device accommodated in the cleaning tank 6100 of the main body base 6000 to perform the cleaning operation. When the automatic cleaning device returns to the self-cleaning maintenance station to perform charging, dust collection, and drying operations, it returns to the self-cleaning maintenance station. At this time, the wet cleaning module at the rear of the automatic cleaning device is located on the self-cleaning maintenance station bottom plate 1000, rather than in the accommodation chamber 7000.

[0034] Fig. 2 is a schematic diagram of a partial structure of a self-cleaning maintenance station implemented according to the present invention. Fig. 3 is a schematic cross-sectional view of a partial structure of a self-cleaning maintenance station implemented according to the present invention. Fig. 4 is a schematic bottom view of a self-cleaning maintenance station implemented according to the present invention, where a cover plate for closing an air passage is not shown. Fig. 5 is a schematic bottom view of a self-cleaning maintenance station implemented according to the present invention.

[0035] As shown in FIGS. 1 to 5 , the self-cleaning maintenance station further includes a drying fan 8100. The drying fan 8100 is provided in the self-cleaning maintenance station main body 2000, located on the side of the receiving chamber 7000 away from the main body base 6000, and configured to blow dry air onto at least a portion of the cleaning tub 6100 to dry the cleaning tub 6100. In this way, the cleaning tub 6100 is prevented from being wet, which could lead to bacterial growth and unpleasant odors. Specifically, the drying fan 8100 is provided above the cleaning tub 6100 and is relatively far away from the cleaning tub 6100. This prevents water from splashing onto the drying fan, which could cause the drying fan to malfunction, compared to when the drying fan is closer to the cleaning tub.

[0036] As shown in FIGS. 1 to 5 , the self-cleaning maintenance station further includes a gas heating device 8200. The gas heating device 8200 is also installed within the self-cleaning maintenance station main body 2000, located downstream of the drying fan 8100 and on the side of the receiving chamber 7000 away from the main body base 6000. The gas heating device 8200 is configured to heat the airflow blown by the drying fan 8100. The gas heating device 8200 is, for example, a PTC heater. A PTC heater is configured using a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency, making it an automatic constant temperature, energy-saving electric heater. Its distinctive feature is its safety performance: unlike electric tubular heaters, it does not exhibit the "reddening" phenomenon on the surface, regardless of application. This prevents safety hazards such as burns or fires.

[0037] In some embodiments, as shown in FIGS. 1 to 5 , the cleaning dust collecting sheet main body 2000 further includes a first dry air duct 9100 for transmitting dry airflow heated by a gas heater 8200. The first dry air duct 9100 extends along the sidewall of the self-cleaning maintenance station main body 2000 in a direction substantially perpendicular to the main body base 6000, and the outlet of the first dry air duct 9100 faces a portion of the cleaning tub 6100. When the cleaning dust collecting sheet performs a drying operation, the dry airflow is heated by the gas heater 8200 by driving the drying fan 8100, and then blown into at least a portion of the cleaning tub 6100 in a direction substantially perpendicular to the main body base 6000. The use of a vertical air duct can reduce wind noise.

[0038] In some embodiments, a filter screen 6110 is provided at the end of the cleaning tank 6100 adjacent to the side wall of the self-cleaning maintenance station body 2000 to filter out impurities in the wastewater in the cleaning tank 6100. The outlet of the first drying air duct is provided toward the filter screen. The hot dry air blows toward the filter screen 6110, passes through the filter screen 6110, and reaches the bottom of the cleaning tank 6100, thereby drying the bottom of the cleaning tank 6100. In this way, it is possible to prevent wastewater from remaining there, which could cause an unpleasant odor and lead to the growth of bacteria.

[0039] In some embodiments, after the automatic cleaning device returns to the self-cleaning maintenance station in the forward direction, the self-cleaning maintenance station may perform a drying operation. At least a portion of the dry airflow blown out from the first dry air duct 9100 flows in the space between the automatic cleaning device and the cleaning tank 6100 along the extension direction of the cleaning tank 6100, away from the filter screen 6110. In this way, the dry airflow completely covers the entire cleaning tank 6100, allowing the drying operation to be performed on the entire cleaning tank 6100.

[0040] In some embodiments, the self-cleaning maintenance station includes a second dry air duct 9200 that extends from the sidewall of the self-cleaning maintenance station main body 2000 through the main body base 6000 to the self-cleaning maintenance station bottom plate 1000 and is configured to blow at least a portion of the dry airflow toward the bottom surface of the automatic cleaning device on the self-cleaning maintenance station bottom plate to dry the wet cleaning module of the automatic cleaning device. As described above, when the automatic cleaning device returns to the self-cleaning maintenance station to perform a drying operation, the automatic cleaning device returns to the self-cleaning maintenance station in the forward direction, with its wet cleaning module supported by the self-cleaning maintenance station bottom plate 1000.

[0041] 1 to 5, the second drying air duct 9200 includes a first sub-drying air duct 9210, a second sub-drying air duct 9220, a third sub-drying air duct 9230, and a fourth sub-drying air duct 9240, which are sequentially connected to each other. The first sub-drying air duct 9210 extends along the side wall of the self-cleaning maintenance station main body 2000 in a direction substantially perpendicular to the main body base 6000. The second sub-drying air duct 9220 extends along the edge of the main body base 6000 toward the self-cleaning maintenance station bottom plate 1000. The third sub-drying air duct 9230 extends along the edge of the self-cleaning maintenance station bottom plate 1000, away from the main body base 6000. The fourth sub-drying air duct 9240 extends inside the self-cleaning maintenance station bottom plate 1000 in a direction substantially perpendicular to the third sub-drying air duct 9230. The heated dry air flow passes through the first sub-drying air duct 9210, the second sub-drying air duct 9220, the third sub-drying air duct 9230, and the fourth sub-drying air duct 9240 in order, and is transmitted to the self-cleaning maintenance station bottom plate 1000 to dry the wet cleaning module of the automatic cleaning device thereon.

[0042] In some embodiments, a second drying air duct outlet 9241 communicating with the fourth sub-drying air duct 9240 is provided on the ceiling wall of the bottom plate 1000 of the self-cleaning maintenance station, and there are multiple second drying air duct outlets 9241 arranged at intervals along the extension direction of the fourth sub-drying air duct. After the automatic cleaning device returns to the self-cleaning maintenance station in the forward direction, the second drying air duct outlet 9241 faces the wet cleaning module of the automatic cleaning device to facilitate drying of the wet cleaning module of the automatic cleaning device.

[0043] In some embodiments, the gas heating device 8200 comprises a protector configured to provide overheat protection for the gas heating device.

[0044] In some embodiments, the self-cleaning maintenance station further includes a temperature sensor provided in at least one of the first dry air duct and the second dry air duct and configured to monitor the temperature of the dry air stream. The self-cleaning maintenance station may adjust the operating state of the gas heating device 8200 according to the detected temperature of the dry air stream. In this way, damage to the device due to an excessively high temperature of the dry air stream is prevented.

[0045] 1 to 5, the first drying air duct 9100 and the second drying air duct 9200 are collectively referred to as a drying air duct. The first drying air duct 9100 is configured to dry the cleaning tank 6100 by blowing a dry air current onto at least a portion of the cleaning tank, and the second drying air duct 9200 is configured to dry the wet cleaning module of the automatic cleaning device by blowing a dry air current onto the bottom of the automatic cleaning device on the self-cleaning maintenance station bottom plate 1000.

[0046] The drying fan 8100 is provided in the self-cleaning maintenance station main body 2000, and supplies power so that a dry airflow is transmitted through at least one of the first dry air duct 9100 and the second dry air duct 9200. The gas heating device 8200 is provided between the drying fan and the dry air duct, and is configured to heat the airflow blown from the drying fan 8100. The heated airflow is transmitted to at least one of the first dry air duct 9100 and the second dry air duct 9200.

[0047] In some embodiments, the air inlet of the first drying duct 9100 and the air inlet of the second drying duct 9200 are arranged in parallel to simultaneously receive the dry airflow, i.e., when the self-cleaning maintenance station performs a drying operation, the cleaning tank 6100 and the wet cleaning module of the automatic cleaning equipment are simultaneously dried.

[0048] When drying the cleaning tank 6100 and the wet cleaning module of the automatic cleaning equipment, it is necessary to complete the drying operations as simultaneously as possible, so it is necessary to allocate the airflow rates of the first drying air duct and the second drying air duct so that the airflow rates of the first drying air duct and the second drying air duct per unit time are in a predetermined ratio. In this way, simultaneous drying of the cleaning tank 6100 and the wet cleaning module of the automatic cleaning equipment is guaranteed, improving drying efficiency.

[0049] In some embodiments, the first air intake area of ​​the air intake port of the first drying air duct and the second air intake area of ​​the air intake port of the second drying air duct have a predetermined ratio to dry the hot air, so that the airflow rates of the first drying air duct and the second drying air duct per unit time have a predetermined ratio. In some embodiments, the ratio of the first air intake area of ​​the air intake port of the first drying air duct and the second air intake area of ​​the air intake port of the second drying air duct is 1:5 to 4:5, for example 3:5.

[0050] In some embodiments, as shown in FIGS. 1 to 5 and described above, the self-cleaning maintenance station includes a dust collection tank 3000 configured to collect dust from the automatic cleaning device. A self-cleaning maintenance station base plate 1000 is detachably connected to the self-cleaning maintenance station body 2000 and supports a portion of the automatic cleaning device when the automatic cleaning device is returned to the self-cleaning maintenance station. The self-cleaning maintenance station base plate 1000 is provided with a dust collection port 1100 configured to communicate with the dust suction port of the automatic cleaning device. When the automatic cleaning device returns to the self-cleaning maintenance station in the forward direction, the dust collection port 1100 on the cleaning dust collection sheet base plate 1000 is in sealed communication with the dust suction port of the automatic cleaning device, facilitating the dust collection operation of the self-cleaning maintenance station. The self-cleaning maintenance station has a dust collection air duct 9300 that extends from the self-cleaning maintenance station base plate 1000 to the self-cleaning maintenance station main body 2000 and connects the dust collection port 1100 to the dust collection tank 3000. The dry air duct of the self-cleaning maintenance station is, for example, a second dry air duct 9200 that extends from the self-cleaning maintenance station main body 200 to the self-cleaning maintenance station base plate 1000, with the second dry air duct 9200 and the dust collection air duct 9100 extending at least partially in parallel and adjacent to each other. This arrangement makes the layout of the dry air duct and the dust collection air duct more rational, making the overall structure of the cleaning dust collection sheet more compact and reducing its dimensions.

[0051] In some embodiments, the second drying air duct 9200 and the dust collecting air duct 9300 at least partially overlap on the bottom plate of the self-cleaning maintenance station, for example, at least partially overlap on the edge of the bottom plate 1000 of the self-cleaning maintenance station.

[0052] In some embodiments, as shown in Figures 1 to 5, one side edge of the self-cleaning maintenance station bottom plate 1000 has a protrusion structure 1300, and a portion of the second drying air duct 9200 is formed in the protrusion structure 1300, for example, a third sub-drying air duct 9230 is provided in the protrusion structure 1300, and a portion of the dust collection air duct 9300 is formed in the self-cleaning maintenance station bottom plate 1000 and is located directly below the protrusion structure 1300.

[0053] The protrusion structure 1300 can limit the position of the automatic cleaning device when it is returning to the self-cleaning maintenance station, thereby preventing the automatic cleaning device from failing to return to the self-cleaning maintenance station correctly due to misalignment when it returns to the cleaning dust collection sheet.

[0054] The several dust collection ducts 9300 include a first sub-dust collection duct 9310, a second sub-dust collection duct 9320, a third sub-dust collection duct 9330, and a fourth sub-dust collection duct 9340 which are sequentially connected to each other.

[0055] The first sub-dust collection air duct 9310 extends along the side wall of the self-cleaning maintenance station main body 2000 in a direction approximately perpendicular to the main body base 6000, the first sub-dust collection air duct 9310 and the first sub-drying air duct 9210 are arranged adjacent to each other in parallel, and the first sub-dust collection air duct 9319 is farther from the self-cleaning maintenance station bottom plate 1000 than the first sub-drying air duct 9210.

[0056] The second sub-dust collection air duct 9320 extends along the edge of the main body base 6000 toward the self-cleaning maintenance station bottom plate 1000, and the second sub-dust collection air duct 9320 and the second sub-drying air duct 9220 are arranged adjacent to each other in parallel, and the orthogonal projection of the second sub-drying air duct 9220 on the bottom surface of the main body base and the orthogonal projection of the second sub-dust collection air duct 9320 on the bottom surface of the main body base at least partially overlap.

[0057] The edge of the third sub-dust collection air duct 9330 along the bottom plate 1000 of the self-cleaning maintenance station extends away from the main body base 6000, the third sub-dust collection air duct 9330 and the third sub-drying air duct 9230 are arranged adjacent to each other in parallel, and the orthogonal projection of the third sub-drying air duct 9230 on the bottom surface of the bottom plate of the self-cleaning maintenance station at least partially overlaps with the orthogonal projection of the third sub-dust collection air duct 9330 on the bottom surface of the bottom plate of the self-cleaning maintenance station.

[0058] The fourth sub-dust collection air duct 9340 extends inside the self-cleaning maintenance station bottom plate 1000 in a direction substantially perpendicular to the third sub-dust collection air duct 9330, and the fourth sub-dust collection air duct 9340 and the fourth sub-drying air duct 9240 are arranged adjacent to each other in parallel. The fourth sub-dust collection air duct 9340 is closer to the main body base 6000 than the fourth sub-drying air duct 9240.

[0059] When the self-cleaning maintenance station bottom plate 1000 and the main body base 6000 of the self-cleaning maintenance station main body 2000 are detachably connected, the third sub-dust collection air duct 9330 provided on the self-cleaning maintenance station bottom plate 1000 and the second sub-dust collection air duct 9320 provided on the cleaning dust collection sheet main body 2000 are joined together and communicate with each other, for example, in a sealed manner. The third sub-drying air duct 9230 provided on the self-cleaning maintenance station bottom plate 1000 and the second sub-drying air duct 9220 provided on the cleaning dust collection sheet main body 2000 are joined together and communicate with each other, for example, in a sealed manner.
