Description

Technical Field

[0001] This application relates to the field of manufacturing base stations for cleaning equipment, and more particularly to a base station for cleaning equipment and a cleaning system. Background Technology

[0002] Intelligent home appliances, especially cleaning robots, are currently a hot topic. To meet user needs, current cleaning robots can not only perform cleaning but also work in conjunction with a matching base station to clean the robot.

[0003] However, after a certain period of use, when the base station cleans the cleaning unit of the cleaning robot, bacteria are present in the cleaning unit and the sewage, which leads to a decrease in the cleanliness of the base station and the cleaning robot, affecting the user experience. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a base station and cleaning system for a cleaning device capable of sterilizing cleaning units and wastewater.

[0005] The first aspect of this application provides a base station for a cleaning device, comprising: a cleaning section for cleaning the cleaning device; and a sterilization device disposed in or adjacent to the cleaning section, wherein the sterilization device sterilizes at least a portion of the cleaning section.

[0006] In this embodiment of the application, by setting up a sterilization device and cleaning part of the cleaning section, the sewage can be sterilized, which helps to reduce the bacteria in the sewage, maintain the cleanliness of the base station and the cleaning equipment, and thus maintain the cleaning effect of the cleaning equipment.

[0007] In this embodiment, the sterilization device includes an emitting end that emits ultraviolet light for sterilization, and the ultraviolet light emitted by the sterilization device covers at least a portion of the cleaning section.

[0008] In this embodiment, the cleaning unit includes: a cleaning tray for accommodating the cleaning unit being cleaned and collecting wastewater generated during the cleaning of the cleaning unit; a sterilization device located on or near the cleaning tray; and ultraviolet light emitted by the sterilization device covering at least a portion of the cleaning tray.

[0009] The sterilization device is located in or near the cleaning tray and can sterilize the wastewater in the cleaning tray. The cleaning equipment is housed in the cleaning tray for cleaning. The sterilization device sterilizes the water in the cleaning tray, reduces the bacteria in the wastewater in the clean water tray, and can further reduce the bacteria in the cleaning unit, which helps to improve the cleanliness of the cleaning unit.

[0010] In this embodiment of the application, the cleaning pan further includes: a water receiving pan for receiving wastewater from the cleaning pan, the water receiving pan being located downstream of the cleaning pan, and a sterilization device being located at or near the position where the cleaning pan is connected to the water receiving pan, and the ultraviolet light emitted by the sterilization device covering at least a portion of the cleaning pan and at least a portion of the water receiving pan.

[0011] Wastewater in the clean water tray is sterilized before entering the drip tray and being discharged, which reduces the number of bacteria in the wastewater in the drip tray. This allows for simultaneous sterilization of wastewater in both the cleaning tray and the drip tray, improving the cleanliness of the cleaning area.

[0012] In this embodiment, the water receiving tray has a drain outlet, through which wastewater in the cleaning section is discharged.

[0013] In this embodiment, the cleaning unit further includes a scrubbing assembly for cleaning the cleaning unit. The cleaning is achieved through relative movement between the scrubbing assembly and the cleaning unit. Ultraviolet light emitted by the emitting end covers at least a portion of the scrubbing assembly.

[0014] The ultraviolet light emitted by the transmitter can cover the washing components, thereby sterilizing them and reducing bacteria on the washing components.

[0015] In this embodiment of the application, the sterilization device is positioned above the bottom of the washing tray and the bottom of the water receiving tray in the direction of gravity.

[0016] This prevents the sterilization device from being obstructed by sewage.

[0017] In this embodiment of the application, the emitting end is set higher than the bottom of the cleaning tray and the bottom of the water receiving tray in the direction of gravity; the field of view of the ultraviolet light emitted by the emitting end on the horizontal plane is greater than or equal to 120°, and / or the wavelength range of the emitting end is in the 180nm-190nm band and / or the 240nm-260nm band.

[0018] Therefore, the ultraviolet light emitted by the transmitter can sterilize within a field of view of 120° or greater, thus expanding the sterilization range. Ultraviolet light in the 180nm-190nm band can produce ozone, which can sterilize and disinfect. Ultraviolet light in the 240nm-260nm band can damage the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, causing DNA strand breaks, cross-linking and rupture of nucleic acids and proteins, resulting in both vegetative and regenerative cell death, achieving the effect of sterilization and disinfection.

[0019] In this embodiment of the application, the base station is provided with an opening, and the cleaning equipment enters the base station through the opening so that the cleaning unit is accommodated in the cleaning section; the sterilization device includes a shielding section, and the transmitter and the shielding section are arranged in sequence on the emission path of the ultraviolet light emitted by the transmitter, and the shielding section blocks part of the transmitter to prevent the ultraviolet light from being emitted through the opening.

[0020] The shielding part blocks ultraviolet rays from escaping, which can prevent ultraviolet rays from escaping outside the base station and causing damage to users.

[0021] In this embodiment, the shielding portion includes a filter for filtering ultraviolet rays to block the ultraviolet rays from escaping through the opening; and / or the shielding portion includes electrochromic glass, which transmits ultraviolet rays when the cleaning unit is housed in the cleaning section for cleaning, and blocks ultraviolet light transmission when the cleaning equipment performs a cleaning operation.

[0022] By incorporating electrochromic glass, ultraviolet light is allowed to pass through during cleaning for disinfection, enhancing both the effectiveness and coverage of the disinfection process. When cleaning equipment performs cleaning operations outside the base station, the electrochromic glass blocks ultraviolet light transmission, preventing harm to users.

[0023] In this embodiment of the application, the sterilization device includes an ozone generator, which provides ozone to sterilize the cleaning section, the cleaning unit, and / or wastewater.

[0024] Ozone generators produce ozone, which can sterilize and disinfect, thus enhancing the sterilization effect of the sterilization device.

[0025] In this embodiment of the application, the sterilization device includes a seal; the seal is at least disposed at the top of the emitting end in the direction of gravity, or the seal covers the emitting end, and the seal is configured to transmit ultraviolet light.

[0026] The sealing element prevents wastewater from the cleaning tray from entering the sterilization device.

[0027] A second aspect of this application provides a base station for a cleaning device, comprising: a cleaning device; and a base station for the cleaning device as described in the first aspect.

[0028] In this embodiment of the application, by providing a sterilization device that emits ultraviolet light, and the ultraviolet light emitted by the sterilization device covers at least part of the cleaning unit and part of the washing section, the cleaning unit and sewage can be sterilized, which helps to reduce bacteria in the cleaning unit and sewage and maintain the cleanliness of the cleaning system.

[0039] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0040] Intelligent home appliances, especially cleaning robots, are currently a hot topic. To meet user needs, current cleaning robots can not only perform cleaning but also work in conjunction with a matching base station to clean the robot.

[0041] However, after a certain period of use, when the base station cleans the cleaning unit of the cleaning robot, bacteria are present in the cleaning unit and the sewage, which leads to a decrease in the cleanliness of the base station and the cleaning robot, affecting the user experience.

[0042] To address the aforementioned technical problems, this application provides a base station for a cleaning device capable of sterilizing cleaning units and wastewater. Based on the same concept, this application also provides a cleaning system, which includes cleaning equipment and a base station for the cleaning equipment capable of sterilizing cleaning units and wastewater.

[0043] The base station of the provided cleaning equipment may include: a cleaning unit for cleaning the cleaning unit of the cleaning equipment; and a sterilization device disposed in the cleaning unit, the sterilization device including a transmitter that emits ultraviolet light for sterilization, the ultraviolet light emitted by the sterilization device covering at least a portion of the cleaning unit.

[0044] Figure 1 This application provides schematic diagrams of the structure of a cleaning system in which cleaning equipment performs cleaning operations, based on some embodiments of the present application. Figure 2 A schematic diagram of the structure of a cleaning system located at a base station, provided in some embodiments of this application; Figure 3 A schematic diagram of the exploded structure of a base station provided for some embodiments of this application; Figure 4 A bottom view of the cleaning equipment provided for some embodiments of this application; Figure 5 Schematic diagrams of the cleaning section provided for some embodiments of this application; Figure 6 for Figure 5 An enlarged view of part A in the image; Figure 7 This is a schematic diagram of the sterilization device provided for some embodiments of this application.

[0045] like Figures 1 to 7 As shown, this application provides a cleaning system 1, which may include a base station 10 and a cleaning device 20. In this application, the cleaning device 20 may include a cleaning unit for performing cleaning. The cleaning device 20 may be an automatic cleaning device, such as a sweeper, a sweeper-mop combo, or a floor scrubber. Figure 4As shown, the cleaning device 20 may have a moving part 200, which can move by moving the cleaning device 200. The moving part 200 may be a roller. The cleaning device 20 may be provided with a cleaning unit for cleaning. The cleaning unit may be a module in the cleaning device that performs cleaning operations, such as a module with a sweeping brush in a sweeping robot, or a module with a mop in a mopping robot.

[0046] like Figures 1 to 3 As shown, base station 10 can be used for charging, cleaning, etc., of cleaning equipment 20. Base station 10 may have an opening 100 through which cleaning equipment 20 can enter base station 10. Base station 10 may have a cleaning unit 11, which may be located on the base 110 of base station. Cleaning unit 11 can be used to clean the cleaning unit of cleaning equipment 20 and collect wastewater. Figure 2 As shown, the cleaning device 20 can enter the base station 10 through the opening 100. After entering the base station 10, the cleaning unit is housed in the cleaning section 11 for cleaning. After cleaning is completed, the wastewater in the cleaning section 11 can be discharged through the drain outlet of the cleaning section 11.

[0047] like Figure 3 As shown in this embodiment, the cleaning unit 11 may include a cleaning tray 111 and a water receiving tray 112. The cleaning tray 111 can be used to collect wastewater generated during the cleaning of the cleaning unit, and the cleaning unit of the cleaning device 20 can be accommodated in the cleaning tray 111 for cleaning. The water receiving tray 112 can be used to receive wastewater from the cleaning tray 111, and the water receiving tray 112 is located downstream of the cleaning tray 111. For example, the water receiving tray 112 can be disposed on one side of the cleaning tray 111. The water receiving tray 112 has a drain outlet, through which wastewater in the cleaning unit 11 can be discharged.

[0048] In this embodiment, the base station 10 may have a sterilization device 13, which may be located on the cleaning tray 111. However, this application is not limited to this; in some embodiments, the sterilization device 13 may also be disposed adjacent to the cleaning tray 111, for example, above the cleaning tray 111. The sterilization device 13 can sterilize at least a portion of the cleaning section 11.

[0049] In this embodiment, the sterilization device 13 can be an ultraviolet sterilization device that sterilizes by emitting ultraviolet light. For example, the ultraviolet light emitted by the sterilization device 13 covers at least a portion of the washing tray 111. However, this disclosure is not limited to this; in some embodiments, the sterilization device may also be located in the water receiving tray.

[0050] The sterilization device is located in or near the cleaning tray and sterilizes the wastewater in the cleaning tray. After sterilization, the wastewater in the clean water tray is discharged into the receiving tray, reducing bacteria in the wastewater there. Furthermore, since the cleaning equipment is housed in the cleaning tray, the sterilization device sterilizes the water in the cleaning tray, reducing bacteria in the wastewater in the clean water tray, which further reduces bacteria in the cleaning unit, thus improving the cleanliness of the cleaning unit.

[0051] In this embodiment, the base station may be equipped with a wastewater tank, into which wastewater can enter after being discharged through the drain outlet of the cleaning section. This application uses a sterilization device to reduce bacteria in the wastewater; for example, when wastewater is discharged into the wastewater tank, the level of contamination in the tank can be prevented from increasing. In some embodiments of this application, the base station may be configured for automatic water supply and drainage. Reducing bacteria in the wastewater through the sterilization device can lower the level of contamination in the drainage channel, avoiding frequent disassembly and cleaning and improving the user experience.

[0052] In the embodiments of this application, such as Figure 5 and Figure 6 As shown, the sterilization device 13 can be located at or near the position where the cleaning tray 111 connects to the water receiving tray 112. Specifically, the sterilization device 13 can be positioned near the position where the clean water tray 111 connects to the water receiving tray 112. The ultraviolet light emitted by the sterilization device 13 can cover at least a portion of the cleaning tray 111 and a portion of the water receiving tray 112. This arrangement allows for simultaneous sterilization of wastewater in both the cleaning tray and the water receiving tray, improving the cleanliness of the cleaning section.

[0053] In the embodiments of this application, such as Figure 6 As shown, the water receiving tray 112 may be equipped with a filter element 113, which can block impurities flowing into the water receiving tray 112 and prevent impurities from being discharged from the drain outlet of the water receiving tray 112, causing blockage or pollution.

[0054] In the embodiments of this application, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the cleaning unit 11 may include a scrubbing assembly 14, which can be used to clean the cleaning unit. The scrubbing assembly 14 can achieve cleaning through relative movement with the cleaning unit. The scrubbing assembly 14 moves along a first direction X between two oppositely disposed sides of the cleaning disc 111. The first side 101 of the cleaning disc 111 may be parallel to the first direction X. One side and the other side of the cleaning disc 111 may be a second side 102 and a third side 103, respectively. A water receiving tray 112 may be disposed on the third side 103, and a sterilization device 13 may be located on the third side 103.

[0055] In this embodiment, the ultraviolet light emitted by the transmitter 130 can cover at least a portion of the washing assembly 14. This ultraviolet light can sterilize the washing assembly 14, reducing bacteria on it. Reduced bacteria on the washing assembly 14 leads to a corresponding reduction in bacteria on the cleaning unit cleaned by the washing assembly 14, thus improving the overall cleanliness of the cleaning system 1. Furthermore, the improved overall cleanliness of the cleaning system 1 can extend the time required for customer replacement and cleaning of the washing assembly, cleaning unit, and cleaning section, or reduce the frequency of such replacements and cleanings, thereby enhancing the user experience.

[0056] In this embodiment, the washing assembly 14 may include a cleaning brush 141 and a squeegee 142. The cleaning brush 141 may be rotatable and used for cleaning the cleaning unit. The squeegee 142 may scrape impurities, mud, and sediments from the bottom 1110 of the cleaning disc 111 into the water receiving disc 112 as the washing assembly 14 moves upward.

[0057] In the embodiments of this application, such as Figure 5 and Figure 6 As shown, in the gravitational direction Y, the sterilization device 13 can be positioned higher than the bottom 1110 of the cleaning tray 111 and the bottom of the water receiving tray 112. This arrangement can prevent the sterilization device from being obstructed by sewage.

[0058] In this embodiment, the transmitter 130 can be positioned higher than the bottom 1110 of the cleaning tray 111 and the bottom of the water receiving tray 112 in the gravitational direction Y. This arrangement can prevent the transmitter from being blocked by sewage.

[0059] In the embodiments of this application, such as Figure 5 and Figure 6 As shown, the sterilization device 13 may include a shielding part 131. The transmitter 130 and the shielding part 131 are sequentially arranged along the emission path of the ultraviolet light emitted by the transmitter 130. The shielding part 131 can shield a portion of the transmitter 130 to prevent ultraviolet light from escaping through the opening. The shielding part 131 blocks the ultraviolet light emission, preventing it from escaping outside the base station 10 and causing damage to the user.

[0060] In some embodiments of this application, the shielding portion 131 can be screen-printed with ink and applied to the emitting surface of the emitting end. In some embodiments of this application, the shielding portion 131 can be a light-shielding film or a light-shielding layer.

[0061] In this embodiment, the shielding portion 131 may include a filter for filtering ultraviolet light to block it from escaping through the opening 100. The filter can filter ultraviolet light, preventing it from escaping to the outside of the base station 10 and causing damage to the user.

[0062] In this embodiment, the blocking part 131 may include electrochromic glass. When the cleaning unit is housed in the cleaning part 11 for cleaning, the electrochromic glass can transmit ultraviolet rays. When the cleaning equipment performs a cleaning operation, the electrochromic glass blocks the transmission of ultraviolet rays. For example, a control module may be provided in the base station 10. The control module can be signal-connected to the electrochromic glass, and the control module can control the electrochromic glass to change according to the working status of the cleaning unit 20 and the base station 10.

[0063] By incorporating electrochromic glass, ultraviolet light is allowed to pass through during cleaning for disinfection, enhancing both the effectiveness and coverage of the disinfection process. When cleaning equipment performs cleaning operations outside the base station, the electrochromic glass blocks ultraviolet light transmission, preventing harm to users.

[0064] In this embodiment, the sterilization device 13 may include an ozone generator. The ozone generator produces ozone, which can sterilize and disinfect one or more of the cleaning section, cleaning unit, and sewage, thereby enhancing the sterilization effect of the sterilization device.

[0065] Figure 6 The diagram shows the decomposition state of the sterilization device 13. Figure 6 As shown, the sterilization device 13 may include a seal 132, which is at least located at the top of the emitter 130 in the gravitational direction Y. The seal prevents wastewater from the cleaning tray 111 from entering the sterilization device 13 and damaging the emitter 130.

[0066] However, this disclosure is not limited to this; the seal can also be configured to cover the emitting end. For example, the seal can be configured to include the emitting end. In this application, the seal can be configured to transmit ultraviolet light, thus preventing interference with ultraviolet light emission while providing a seal.

[0067] In this application, by providing a sterilization device that emits ultraviolet light, and the ultraviolet light emitted by the sterilization device covers at least part of the cleaning unit and part of the washing section, the cleaning unit and sewage can be sterilized, which helps to reduce bacteria in the cleaning unit and sewage, maintain the cleanliness of the base station and cleaning equipment, and thus maintain the cleaning effect of the cleaning equipment.

[0068] In the embodiments of this application, such as Figure 7 As shown, the ultraviolet light emitted by the emitting end 130 of the sterilization device 13 has a field of view α on the horizontal plane that is greater than or equal to 120°. The ultraviolet light emitted by the emitting end can sterilize within a field of view greater than or equal to 120°, thereby increasing the sterilization range.

[0069] In the embodiments of this application, the emitting end 130 can emit ultraviolet light with a wavelength range of 180nm-190nm, for example, it can emit ultraviolet light with a wavelength of 185nm. Ultraviolet light in the 180nm-190nm band can generate ozone, which can sterilize and disinfect.

[0070] In the embodiments of this application, the emitting end 130 can emit ultraviolet light with a wavelength range of 240nm-260nm. For example, it can emit ultraviolet light with a wavelength of 253.7nm. Ultraviolet light in the 1240nm-260nm wavelength range can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, causing DNA strand breaks, cross-linking and rupture of nucleic acids and proteins, resulting in growth cell death and regenerative cell death, thus achieving the effect of sterilization and disinfection.

[0071] In the embodiments of this application, the transmitter 130 can emit ultraviolet light with wavelengths in the 180nm-190nm and 240nm-260nm bands. The transmitter 130 can simultaneously emit ultraviolet light with wavelengths in both bands. The transmitter 130 can also emit ultraviolet light with wavelengths in different bands under different conditions. For example, through the control module of the base station 10, the transmitter 130 can be specifically controlled to emit ultraviolet light with corresponding wavelength bands according to the specific operating status of the base station 10 and the cleaning equipment 20.

[0072] In this application, by incorporating a sterilization device that emits ultraviolet light, and ensuring that the emitted ultraviolet light covers at least a portion of the cleaning unit and a portion of the washing section, the cleaning unit and wastewater can be sterilized. This helps reduce bacteria in the cleaning unit and wastewater, maintaining the cleanliness of the cleaning system. This design reduces bacteria in the cleaning system and prevents odor problems, thereby improving the user experience.
