[0049] The light emitting assembly 100 provided by the present disclosure embodiment includes a housing piece 10, a protection piece 20 and a light emitting piece 30, the protection piece 20 and the housing piece 10 are connected, and a closed accommodation space is formed between the protection piece 20 and the housing piece 10, the protection piece 20 can transmit light, the light emitting piece 30 is arranged in the accommodation space, and the light emitting piece 30 is used for emitting sterilization light, the sterilization light emitted by the light emitting piece 30 realizes sterilization of the cleaning device, thereby at least to some extent inhibiting odor generation of the cleaning device. And the closed accommodation space is formed by the housing piece 10 and the protection piece 20, and the light emitting piece 30 is arranged in the accommodation space, which realizes protection of the light emitting piece 30, and avoids corrosion of the light emitting piece 30.

[0050] The parts of the light-emitting assembly 100 provided by the embodiments of the present disclosure will be described in detail below.

[0051] The housing part 10 and the protection part 20 are connected to form a closed accommodation space, and the light-emitting part 30 is arranged in the accommodation space. The accommodation space can be formed by a recess on the housing part 10, or the accommodation space can be formed by a recess on the protection part 20.

[0052] In some embodiments, the housing part 10 can include a substrate 11 and a protection support 12, the light-emitting part 30 is arranged on the substrate 11, the protection support 12 is connected to the substrate 11, the protection support 12 is provided with an accommodation hole 121, the light-emitting part 30 is at least partially located in the accommodation hole 121, and the protection part is blocked in the accommodation hole 121 to form the accommodation space.

[0053] The first solder pad 101 and the second solder pad 102 are arranged on the substrate 11, and the first solder pad 101 and the second solder pad 102 are arranged on both sides of the light-emitting part 30, respectively. The first solder pad 101 and the second solder pad are electrically connected to the light-emitting part 30, respectively.

[0054] The substrate 11 can be provided with a light-emitting area, a first connection area and a second connection area, the light-emitting area is used to mount the light-emitting part 30, and the first connection area and the second connection area are arranged on both sides of the light-emitting area. The first solder pad 101 is arranged in the first connection area, and the second solder pad 102 is arranged in the second connection area. There is a gap between the first connection area and the light-emitting area, and there is a gap between the second connection area and the light-emitting area.

[0055] The first solder pad 101 and the second solder pad 102 are used to connect external wires to transmit driving current to the light-emitting part 30. The first solder pad 101 and the external power line can be connected by soldering or the like, and the second solder pad 102 and the external power line can be connected by soldering or the like. The first connection wire and the second connection wire are arranged on the substrate 11, the first connection wire extends from the first solder pad 101 to the light-emitting area and is connected to the first electrode of the light-emitting part 30, and the second connection wire extends from the second solder pad 102 to the light-emitting area and is connected to the second electrode of the light-emitting part 30.

[0056] For example, the substrate 11 can be a printed circuit board (PCB) on which the light-emitting element is mounted, the printed circuit board is provided with the first solder pad 101 and the second solder pad 102, the first solder pad 101 is connected to the light-emitting element through the first wire on the printed circuit board, and the second solder pad 102 is connected to the light-emitting element through the second wire on the printed circuit board.

[0057] The protection support 12 is provided with a receiving hole 121, which is a through hole. When the protection support 12 is connected to the substrate 11, the light emitting element 30 is located in the receiving hole 121, and the sterilization light emitted by the light emitting element 30 is irradiated outward through the receiving hole 121. On the one hand, the protection support 12 can protect the light emitting element 30, and on the other hand, the protection support 12 can guide the light emitted by the light emitting element 30, so that the light emitted by the light emitting element 30 can irradiate the preset area.

[0058] The protection support 12 is provided with a first avoiding gap 122 and a second avoiding gap 123. The first pad 101 is at least partially located in the first avoiding gap 122, and the second pad 102 is at least partially located in the second avoiding gap 123.

[0059] The protection support 12 can include a main body part, which is a rectangular or approximately rectangular flat plate structure. The receiving hole 121 penetrating the main body part is arranged in the central region of the main body part. The first avoiding gap 122 and the second avoiding gap 123 are arranged on the main body part, and the first avoiding gap 122 and the second avoiding gap 123 are located at both ends of the receiving hole 121 along a first direction, which is the length direction of the main body part. The first avoiding gap 122 and the second avoiding gap 123 are arranged on the side of the main body part facing the substrate 11, and the first avoiding gap 122 and the second avoiding gap 123 do not penetrate the main body part in a second direction, which is perpendicular to the substrate 11.

[0060] The first avoiding gap 122 and the receiving hole 121 have a gap therebetween, and the second avoiding gap 123 and the receiving hole 121 have a gap therebetween. That is, the first avoiding gap 122, the second avoiding gap 123, and the receiving hole 121 are not connected, so as to avoid the first avoiding gap 122 and the second avoiding gap 123 affecting the sealing performance of the receiving space for accommodating the light emitting element 30.

[0061] Further, the protection support 12 can further include a protection part arranged on the side of the main body part away from the substrate 11. The protection part can be a protruding structure on the main body part, and the protection part is annular. The protection element 20 is embedded in the protection part, and the protection element 20 can be prevented from being damaged by vibration or impact during installation or transportation by the protection part.

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

[0063] In order to ensure the sealing performance between the substrate 11 and the protective support 12, the shell member can further comprise a first sealing layer 13, which is arranged between the substrate 11 and the protective support 12 and continuously surrounds the light emitting member 30.

[0064] By arranging the first sealing layer 13 between the substrate 11 and the protective support 12 and continuously surrounding the light emitting member 30, the sealing performance of the light emitting member 30 can be improved, so as to avoid water vapor or impurities from entering the accommodating space in which the light emitting member 30 is arranged, thereby avoiding pollution or corrosion of the light emitting member 30, effectively improving the service life of the light emitting member 30, and avoiding the problem that the cleaning equipment cannot be disinfected completely due to failure of the light emitting member 30.

[0065] When the first avoiding gap 122 and the accommodating hole 121 have a spacing, the sealing layer seals and isolates the first avoiding gap 122 and the accommodating hole 121, that is, the first avoiding gap 122 and the accommodating hole 121 are filled with the sealing layer, so as to avoid the influence of the first avoiding gap 122 on the sealing performance of the accommodating space. When the second avoiding gap 123 and the accommodating hole 121 have a spacing, the sealing layer seals and isolates the second avoiding gap 123 and the accommodating hole 121. That is, the second avoiding gap 123 and the accommodating hole 121 are filled with the sealing layer, so as to avoid the influence of the second avoiding gap 123 on the sealing performance of the accommodating space.

[0066] The first projection area and the second projection area on the first sealing layer 13 are processed by hole digging. The first projection area is the orthographic projection area of the first avoiding gap 122 on the first sealing layer 13, and the second projection area is the orthographic projection area of the second avoiding gap 123 on the first sealing layer 13. By processing the first projection area and the second projection area by hole digging, the influence of the first sealing layer 13 on the connection between the first pad 101, the second pad 102 and the external power supply line can be avoided.

[0067] For example, the first sealing layer 13 can be a double-sided adhesive layer, which is in a continuous state (without cutting) around the light emitting member 30. That is, the double-sided adhesive layer is provided with a through hole corresponding to the accommodating hole 121, which is formed by cutting. In the cutting process, the double-sided adhesive layer around the through hole cannot be cut off. Of course, in actual application, the first sealing layer 13 can also be other sealing structures, such as a sealing gasket, and the embodiments of the present disclosure are not limited thereto.

[0068] The protective member 20 is a light-transmitting plate, which is sealingly connected with the shell member 10. The light-transmitting plate can allow the disinfecting light emitted by the light emitting member 30 to pass through. For example, the protective member 20 can be a quartz glass plate or a transparent plastic plate.

[0069] The shell part 10 is provided with a recess, and the light-transmitting plate is embedded in the recess. The recess can be formed by a protection part on the protection support 12. The light-transmitting plate is embedded in the protection part of the protection support 12, and the height of the protection part is higher than that of the light-transmitting plate. The protection part protects the light-transmitting plate from being damaged during installation or use.

[0070] The light-transmitting plate and the shell part 10 have a second sealing layer, and the second sealing layer continuously surrounds the accommodation space. For example, a sealing glue layer is arranged between the light-transmitting plate and the protection support 12, and the sealing glue layer continuously surrounds the accommodation hole 121 on the protection support 12. The second sealing layer is used to seal the light-transmitting plate and the shell part 10, and is also used to connect the light-transmitting plate and the shell part 10.

[0071] In order to connect the light-emitting assembly 100 and the cleaning device, the shell part 10 can include a first connecting part 40 and a second connecting part 50, and the first connecting part 40 and the second connecting part 50 are respectively located on two sides of the accommodation space. The first connecting part 40 is provided with a first connecting hole 41, and the second connecting part 50 is provided with a second connecting hole 51.

[0072] The protection support 12 can be provided with a first connecting through hole and a second connecting through hole, and the substrate 11 is provided with a third connecting through hole and a fourth connecting through hole. The first connecting through hole and the third connecting through hole are communicated to form the first connecting hole 41, and the second connecting through hole and the fourth connecting through hole are communicated to form the second connecting hole 51.

[0073] In some embodiments, the shell part 10 can include a substrate 11, and the protection part 20 can be a lampshade. The lampshade forms an accommodation space, and the protection part 20 and the substrate 11 are connected to form a closed accommodation space. The lampshade is made of transparent material, and the sterilization light emitted by the light-emitting part 30 passes through the lampshade and irradiates the sewage residual area.

[0074] The lampshade can be a semicircular shell or a cuboid shell, and a sealing layer is arranged between the lampshade and the substrate 11. For example, a double-sided adhesive layer is arranged between the lampshade and the substrate 11. The double-sided adhesive layer can connect the lampshade and the substrate 11, and can also seal the lampshade and the substrate 11.

[0075] The light-emitting part 30 is an ultraviolet light-emitting part 30, for example, the light-emitting part 30 can be an ultraviolet lamp bead. The light-emitting part 30 has a first electrode and a second electrode, and the first electrode is electrically connected to the first bonding pad 101, and the second electrode is electrically connected to the second bonding pad 102. When an external circuit (light-emitting driving circuit) connected to the first bonding pad 101 and the second bonding pad 102 is powered on, the light-emitting part 30 receives a driving current and emits sterilization light. The ultraviolet light-emitting part 30 radiates short-wave sterilization ultraviolet light with a wavelength of 253.7 nm (nanometer) outwardly to disinfect the residual sewage in the cleaning device.

[0076] The light-emitting assembly 100 provided by the embodiments of the present disclosure includes a shell member 10, a protective member 20, and a light-emitting member 30. The protective member 20 is connected to the shell member 10, and a closed accommodation space is formed between the protective member 20 and the shell member 10. The protective member 20 is capable of transmitting light. The light-emitting member 30 is arranged in the accommodation space, and the light-emitting member 30 is configured to emit sterilization light. The sterilization light emitted by the light-emitting member 30 can sterilize the cleaning device, thereby at least partially inhibiting the generation of odor by the cleaning device. The closed accommodation space is formed by the shell member 10 and the protective member 20, and the light-emitting member 30 is arranged in the accommodation space, thereby protecting the light-emitting member 30 from corrosion.

[0077] The embodiments of the present disclosure also provide a cleaning device, as shown in FIGS. 4 and 5. The cleaning device includes a light-emitting assembly 100. The light-emitting assembly 100 includes a shell member 10, a protective member 20, and a light-emitting member 30. The protective member 20 is connected to the shell member 10, and a closed accommodation space is formed between the protective member 20 and the shell member 10. The protective member 20 is capable of transmitting light. The light-emitting member 30 is arranged in the accommodation space, and the light-emitting member 30 is configured to emit sterilization light.

[0078] In some embodiments, the cleaning device is a cleaning base station 210. The cleaning base station 210 further includes a base body 201 having a sewage residue area. The light-emitting assembly 100 is connected to the base body 201, and the light-emitting assembly 100 is configured to irradiate sterilization light to the sewage residue area.

[0079] The base body 201 has a cleaning cavity, and the cleaning area is arranged at the bottom of the cleaning cavity. The light-emitting assembly 100 is arranged at the top of the cleaning cavity. The light-emitting assembly 100 is arranged at the top of the cleaning cavity, so that the sterilization light emitted by the light-emitting assembly 100 can irradiate the sewage residue area at the bottom of the base body 201.

[0080] The sewage residue area is an area in the cleaning base station 210 where sewage is likely to be left. For example, the sewage residue area can be a cleaning area, which is a part of the cleaning base station 210 used for cleaning the cleaning host. Alternatively, the sewage residue area can be a part where sewage is likely to be splashed during cleaning. Alternatively, the sewage residue area can be a position that needs to be passed through when sewage is discharged or collected.

[0081] The shell member 10 comprises a first connecting portion 40 and a second connecting portion 50, and the first connecting portion 40 and the second connecting portion 50 are respectively located on two sides of the accommodating space, the first connecting portion 40 is provided with a first connecting hole 41, and the second connecting portion 50 is provided with a second connecting hole 51. On this basis, as shown in FIG. 6, the cleaning device further comprises a first bolt 202 and a second bolt 203, the first bolt 202 is arranged in the first connecting hole 41 and connected with the station body 201, and the second bolt 203 is arranged in the second connecting hole 51 and connected with the station body 201. The light-emitting assembly 100 is connected to the station body through the first bolt 202 and the second bolt 203, which is convenient to connect and easy to disassemble and maintain.

[0082] It can be understood that the connection mode of the light-emitting assembly 100 and the station body 201 in the embodiments of the present disclosure is not limited to bolt connection, and the light-emitting assembly 100 and the station body 201 can also be connected by riveting, clamping or bonding.

[0083] The cleaning base station 210 can be provided with a first cleaning member and a second cleaning member, the first cleaning member is used for cleaning the main mop, and the second cleaning member is used for cleaning the side mop. The sterilization light emitted by the light-emitting assembly 100 can be used for sterilization of the first cleaning member and the surrounding area thereof.

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

[0085] In the cleaning base station, because there is other functional member directly above the sewage residual area, the light-emitting assembly 100 cannot be arranged directly above the sewage residual area, and when the light-emitting assembly 100 is arranged above the side of the sewage residual area, the sterilization light cannot cover the sewage residual area.

[0086] In order to solve this problem, the light-emitting assembly 100 is configured such that the optical axis of the sterilization light emitted by the light-emitting member 30 has a preset inclination angle with the vertical direction. When the light-emitting assembly 100 is arranged above the side of the sewage residual area, by configuring the light-emitting assembly 100 such that the optical axis of the sterilization light emitted by the light-emitting member 30 has a preset inclination angle with the vertical direction, the optical axis of the sterilization light can be irradiated to the center of the sewage residual area, thereby achieving sterilization of the sewage residual area.
