Detailed Implementation

[0044] The technical solutions in the exemplary embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. The exemplary embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure. Therefore, it should be understood that various modifications and changes can be made to the exemplary embodiments without departing from the scope of protection of this disclosure.

In particular, references to “the / described” object or “a” object are also intended to indicate one of a possible plurality of such objects.

[0046] Unless otherwise specified or stated, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, an electrical connection, or a signal connection; "connection" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0047] In related technologies, a cleaning system may include a cleaning base station and a cleaning host, with the cleaning host equipped with cleaning components (e.g., mopping or washing mechanisms). When the cleaning host is housed within the cleaning base station, the base station can clean the cleaning components on the host. Wastewater generated during cleaning of the host is either discharged from the host or collected in a wastewater tank. However, in practical applications, the discharge or collection of wastewater is often incomplete, resulting in wastewater residue within the cleaning base station. This residual wastewater can easily produce unpleasant odors due to the action of bacteria and other microorganisms.

[0048] The exemplary embodiments of this disclosure first provide a light-emitting component 100 for sterilizing cleaning equipment. As shown in Figures 1, 2 and 3, the light-emitting component 100 includes a housing 10, a protective component 20 and a light-emitting component 30. The protective component 20 and the housing 10 are connected, and a closed accommodating space is formed between the protective component 20 and the housing 10. The protective component 20 is light-transmitting. The light-emitting component 30 is disposed in the accommodating space and is used to emit sterilizing light.

[0049] The light-emitting component 100 provided in this embodiment includes a housing 10, a protective component 20, and a light-emitting component 30. The protective component 20 and the housing 10 are connected, and a closed accommodating space is formed between the protective component 20 and the housing 10. The protective component 20 is light-transmitting. The light-emitting component 30 is disposed in the accommodating space and is used to emit bactericidal light. By emitting bactericidal light, the cleaning equipment is sterilized, thereby at least to a certain extent suppressing the generation of odors by the cleaning equipment. Furthermore, the closed accommodating space formed by the housing 10 and the protective component 20, with the light-emitting component 30 disposed within this accommodating space, protects the light-emitting component 30 and prevents it from being corroded.

[0050] The following will describe in detail the various parts of the light-emitting component 100 provided in the embodiments of this disclosure:

[0051] The housing 10 and the protective member 20 are connected to form a closed accommodating space, and the light-emitting member 30 is disposed within the accommodating space. The accommodating space may be formed by a recess on the housing 10, or it may be formed by a recess on the protective member 20.

[0052] In some embodiments, the housing 10 may include a substrate 11 and a protective bracket 12, with the light-emitting element 30 disposed on the substrate 11; the protective bracket 12 is connected to the substrate 11, and the protective bracket 12 is provided with a receiving hole 121, with the light-emitting element 30 at least partially located in the receiving hole 121, and the protective element sealing the receiving hole 121 to form a receiving space.

[0053] The substrate 11 is provided with a first pad 101 and a second pad 102. The first pad 101 and the second pad 102 are respectively located on both sides of the light-emitting element 30, and the first pad 101 and the second pad are electrically connected to the light-emitting element 30.

[0054] The substrate 11 may have a light-emitting area, a first connection area, and a second connection area. The light-emitting area is used to mount the light-emitting component 30, and the first and second connection areas are respectively located on both sides of the light-emitting area. A first pad 101 is located in the first connection area, and a second pad 102 is located in the second connection area. There is a gap between the first connection area and the light-emitting area, and there is also a gap between the second connection area and the light-emitting area.

[0055] The first pad 101 and the second pad 102 are used to connect external traces to transmit driving current to the light-emitting element 30. The first pad 101 and the external power line can be connected by soldering or the same method. A first connection trace and a second connection trace are provided on the substrate 11. The first connection trace extends from the first pad 101 to the light-emitting area and is connected to the first electrode of the light-emitting element 30. The second connection trace extends from the second pad 102 to the light-emitting area and is connected to the second electrode of the light-emitting element 30.

[0056] For example, substrate 11 may be a printed circuit board (PCB), on which the light-emitting element is mounted. The PCB has a first pad 101 and a second pad 102. The first pad 101 is connected to the light-emitting element through a first trace on the PCB, and the second pad 102 is connected to the light-emitting element through a second trace on the PCB.

[0057] The protective bracket 12 is provided with a receiving hole 121, which is a through hole. When the protective bracket 12 is connected to the substrate 11, the light-emitting element 30 is located inside the receiving hole 121, and the bactericidal light emitted by the light-emitting element 30 shines outward through the receiving hole 121. The protective bracket 12 can protect the light-emitting element 30 on the one hand, and on the other hand, it can also guide the light emitted by the light-emitting element 30 so that the light emitted by the light-emitting element 30 can shine on the preset area.

[0058] The protective bracket 12 is provided with a first clearance notch 122 and a second clearance notch 123. The first pad 101 is at least partially located in the first clearance notch 122, and the second pad 102 is at least partially located in the second clearance notch 123.

[0059] The protective bracket 12 may include a main body, which is a rectangular or approximately rectangular flat plate structure. A receiving hole 121 penetrating the main body is provided in the central region of the main body. A first clearance notch 122 and a second clearance notch 123 are provided on the main body, located at both ends of the receiving hole 121 along a first direction, which is the length direction of the main body. The first clearance notch 122 and the second clearance notch 123 are provided on the side of the main body facing the substrate 11, and do not penetrate the main body in a second direction, which is perpendicular to the substrate 11.

[0060] There is a gap between the first clearance notch 122 and the receiving hole 121, and there is a gap between the second clearance notch 123 and the receiving hole 121. That is, the first clearance notch 122 and the second clearance notch 123 are not connected to the receiving hole 121, thus avoiding the first clearance notch 122 and the second clearance notch 123 from affecting the sealing of the receiving space of the light-emitting element 30.

[0061] Furthermore, the protective bracket 12 may also include a protective portion, which is located on the side of the main body away from the substrate 11. The protective portion may be a protruding structure on the main body and may be annular. The protective member 20 is embedded in the protective portion, which prevents the protective member 20 from being damaged by vibration or impact during installation or transportation.

[0062] For example, the protective part can be a rectangular or approximately rectangular ring structure. The protective part includes a first protective plate, a second protective plate, a third protective plate, and a fourth protective plate, which are connected sequentially to form a ring structure. The orthographic projection of this ring structure onto the main body surrounds the receiving hole 121, that is, the protective part does not obstruct the receiving hole 121.

[0063] To ensure the sealing performance between the substrate 11 and the protective bracket 12, the housing may also include a first sealing layer 13, which is disposed between the substrate 11 and the protective bracket 12 and continuously surrounds the light-emitting element 30.

[0064] By providing a first sealing layer 13 between the substrate 11 and the protective bracket 12, and by continuously surrounding the light-emitting element 30, the sealing performance of the light-emitting element 30 can be improved, thereby preventing moisture or impurities from entering the housing space where the light-emitting element 30 is installed, contaminating or corroding the light-emitting element 30, thus effectively extending the service life of the light-emitting element 30 and avoiding the problem of incomplete sterilization of cleaning equipment caused by the failure of the light-emitting element 30.

[0065] When there is a gap between the first clearance notch 122 and the receiving hole 121, the sealing layer seals and isolates the first clearance notch 122 and the receiving hole 121. That is, a sealing layer is filled between the first clearance notch 122 and the receiving hole 121 to prevent the first clearance notch 122 from affecting the sealing performance of the receiving space. When there is a gap between the second clearance notch 123 and the receiving hole 121, the sealing layer seals and isolates the second clearance notch 123 and the receiving hole 121. That is, a sealing layer is filled between the second clearance notch 123 and the receiving hole 121 to prevent the second clearance notch 123 from affecting the sealing performance of the receiving space.

[0066] The first projection area and the second projection area on the first sealing layer 13 are perforated. The first projection area is the orthogonal projection area of ​​the first clearance notch 122 on the first sealing layer 13, and the second projection area is the orthogonal projection area of ​​the second clearance notch 123 on the first sealing layer 13. By perforating the first projection area and the second projection area, the first sealing layer 13 can be prevented from affecting the connection between the first pad 101, the second pad 102 and the external power line.

[0067] For example, the first sealing layer 13 can be a double-sided adhesive layer, which is continuous (without cuts) around the light-emitting element 30. That is, the double-sided adhesive layer has through holes corresponding to the receiving hole 121, which are formed by cutting, and the double-sided adhesive around the through holes must not be cut off during the cutting process. Of course, in practical applications, the first sealing layer 13 can also be other sealing structures, such as sealing gaskets, etc., and the embodiments disclosed herein are not limited thereto.

[0068] The protective component 20 is a light-transmitting plate, which is sealed to the housing component 10. The light-transmitting plate allows the bactericidal light emitted by the light-emitting component 30 to pass through. For example, the protective component 20 can be a quartz glass plate or a transparent plastic plate.

[0069] The housing 10 has a recessed portion into which the light-transmitting plate is embedded. This recessed portion may be formed by a protective portion on the protective bracket 12. The light-transmitting plate is embedded in the protective portion of the protective bracket 12, and the height of the protective portion is higher than the height of the light-transmitting plate. The protective portion protects the light-transmitting plate, preventing damage to the light-transmitting plate during installation or use.

[0070] A second sealing layer is provided between the light-transmitting plate and the housing component 10, and the second sealing layer continuously surrounds the accommodating space. For example, a sealant layer is provided between the light-transmitting plate and the protective bracket 12, and the sealant layer continuously surrounds the accommodating hole 121 on the protective bracket 12. The second sealing layer serves to seal the light-transmitting plate and the housing component 10 on one hand, and to connect the light-transmitting plate and the housing component 10 on the other hand.

[0071] In order to connect the light-emitting component 100 and the cleaning equipment, the housing component 10 may include a first connecting portion 40 and a second connecting portion 50, the first connecting portion 40 and the second connecting portion 50 being located on both sides of the accommodating space, the first connecting portion 40 being provided with a first connecting hole 41, and the second connecting portion 50 being provided with a second connecting hole 51.

[0072] The protective bracket 12 may be provided with a first connecting through hole and a second connecting through hole, and a third connecting through hole and a fourth connecting through hole may be provided on the substrate 11. The first connecting through hole and the third connecting through hole are connected to form a first connecting hole 41, and the second connecting through hole and the fourth connecting through hole are connected to form a second connecting hole 51.

[0073] In some embodiments, the housing 10 may include a substrate 11, and the protective member 20 may be a lampshade with an accommodating space formed inside. The protective member 20 and the substrate 11 are connected to form a closed accommodating space. The lampshade is made of a transparent material, and the bactericidal light emitted by the light-emitting element 30 shines through the lampshade onto the wastewater residue area.

[0074] The lampshade can be a semi-circular shell or a cuboid shell, and a sealing layer is provided between the lampshade and the substrate 11. For example, a double-sided adhesive layer is provided between the lampshade and the substrate 11. The double-sided adhesive layer can connect the lampshade and the substrate 11 on one hand, and seal the lampshade and the substrate 11 on the other hand.

[0075] The light-emitting element 30 is an ultraviolet light-emitting element 30, for example, it can be an ultraviolet lamp bead. The light-emitting element 30 has a first electrode and a second electrode. The first electrode is electrically connected to a first pad 101, and the second electrode is electrically connected to a second pad 102. When the external circuit (light-emitting driving circuit) connected to the first pad 101 and the second pad 102 is energized, the light-emitting element 30 receives the driving current and then emits sterilizing light. The ultraviolet light-emitting element 30 radiates short-wave sterilizing ultraviolet light with a wavelength of 253.7 nm to disinfect residual wastewater in the cleaning equipment.

[0076] The light-emitting component 100 provided in this embodiment includes a housing 10, a protective component 20, and a light-emitting component 30. The protective component 20 and the housing 10 are connected, and a closed accommodating space is formed between the protective component 20 and the housing 10. The protective component 20 is light-transmitting. The light-emitting component 30 is disposed in the accommodating space and is used to emit bactericidal light. By emitting bactericidal light, the cleaning equipment is sterilized, thereby at least to a certain extent suppressing the generation of odors by the cleaning equipment. Furthermore, the closed accommodating space formed by the housing 10 and the protective component 20, with the light-emitting component 30 disposed within this accommodating space, protects the light-emitting component 30 and prevents it from being corroded.

[0077] This disclosure also provides a cleaning device, as shown in Figures 4 and 5, which includes a light-emitting component 100. The light-emitting component 100 includes a housing 10, a protective component 20, and a light-emitting component 30. The protective component 20 is connected to the housing 10, and a closed accommodating space is formed between the protective component 20 and the housing 10. The protective component 20 is light-transmitting. The light-emitting component 30 is disposed in the accommodating space and is used to emit bactericidal light.

[0078] In some embodiments, the cleaning device is a cleaning base station 210, which also includes a station body 201 having a sewage residue area. A light-emitting component 100 is connected to the station body 201 and is configured to irradiate the sewage residue area with bactericidal light.

[0079] The station body 201 has a cleaning chamber, with a cleaning area located at the bottom of the cleaning chamber and a light-emitting component 100 located at the top of the cleaning chamber. By placing the light-emitting component 100 at the top of the cleaning chamber, the bactericidal light emitted by the light-emitting component 100 can illuminate the wastewater residue area at the bottom of the station body 201.

[0080] The wastewater residue area is the area in the cleaning base station 210 where wastewater is likely to remain. For example, the wastewater residue area can be a cleaning area, which is the part of the cleaning base station used to clean the main unit; or the wastewater residue area can be the part where wastewater is likely to splash during cleaning; or the wastewater residue area can be the location through which wastewater needs to be discharged or collected.

[0081] The housing component 10 includes a first connecting portion 40 and a second connecting portion 50, which are located on opposite sides of the accommodating space. The first connecting portion 40 has a first connecting hole 41, and the second connecting portion 50 is located in the second connecting hole 51. Based on this, as shown in Figure 6, the cleaning equipment also includes a first bolt 202 and a second bolt 203. The first bolt 202 passes through the first connecting hole 41 and connects to the station body 201, and the second bolt 203 passes through the second connecting hole 51 and connects to the station body 201. The first bolt 202 and the second bolt 203 connect the light-emitting component 100 to the station body, facilitating connection and easy disassembly and maintenance.

[0082] It is understood that the connection method between the light-emitting component 100 and the station body 201 in this embodiment is not limited to bolt connection. The light-emitting component 100 and the station body 201 can also be connected by riveting, snap-fitting or gluing.

[0083] The cleaning base station 210 may be equipped with a first cleaning component and a second cleaning component. The first cleaning component is used to clean the main mop, and the second cleaning component is used to clean the side mop. The germicidal light emitted by the light-emitting component 100 can be used to sterilize the first cleaning component and its surrounding area.

[0084] A groove for mounting the light-emitting component 100 can be provided on the station body 201. The shape of the groove matches the shape of the light-emitting component 100. For example, when the light-emitting component 100 has a cuboid or approximately cuboid structure, the groove on the top of the station body 201 is also a cuboid groove.

[0085] In the cleaning base station, since there are other functional components directly above the sewage residue area, the light-emitting component 100 cannot be positioned directly above the sewage residue area. When the light-emitting component 100 is positioned to the side above the sewage residue area, the bactericidal light cannot cover the sewage residue area.

[0086] To address this issue, the light-emitting component 100 is configured such that the optical axis of the bactericidal light emitted by the light-emitting element 30 has a preset tilt angle with the vertical direction. When the light-emitting component 100 is positioned to the side and above the wastewater residue area, by configuring the light-emitting component 100 such that the optical axis of the bactericidal light emitted by the light-emitting element 30 has a preset tilt angle with the vertical direction, the optical axis of the bactericidal light can be directed to the center of the wastewater residue area, thereby achieving sterilization of the wastewater residue area.

[0087] For example, there is a preset tilt angle between the substrate 11 and the bottom surface of the cleaning base station. The light-emitting element 30 is disposed on the substrate 11, and the optical axis of the bactericidal light emitted by the light-emitting element 30 is perpendicular to the substrate 11. By setting the substrate 11 to have a preset tilt angle between it and the bottom surface of the cleaning base station, it is possible to achieve a preset tilt angle between the optical axis of the bactericidal light emitted by the light-emitting element 30 and the vertical direction.

[0088] It should be noted that the preset tilt angle can be determined based on the distance between the light-emitting element 30 and the center of the sewage residue area. For example, if the height difference between the light-emitting element 30 and the center of the sewage residue area is h, and the horizontal distance between the light-emitting element 30 and the center of the sewage residue area is l, the preset tilt angle is arctan(l / h).

[0089] In this embodiment, the cleaning base station 210 is not limited to cleaning the cleaning host; it can also be used to charge the cleaning host. Furthermore, the cleaning base station 210 is equipped with a charging circuit that can connect to an external power source (e.g., a power outlet) and process the externally input power signal before transmitting it to the cleaning host.

[0090] In some embodiments, the cleaning device can be a main cleaning unit, which may be equipped with cleaning components, such as a main mop, side mop, or floor scrubbing mop. Wastewater may easily remain on or around these cleaning components (the wastewater residue area).
