[0051] Figure 1-9 A swimming pool cleaning robot 100 according to a first embodiment of the present invention is shown, including a housing 10 having a receiving cavity 11; a power assembly 20 connected to the housing 10; and a pump assembly 40, a filter assembly 50 and a germicidal lamp assembly 60 installed in the receiving cavity 11.

[0052] The power unit 20 provides power to drive the pool cleaning robot 100 to move within the pool. In this embodiment, the power unit 20 includes a walking component 21 and a drive component 30. The drive component 30 may include a drive motor and a reduction gearbox. The walking component 21 includes a wheel set 22, and the drive component 30 is driven to the wheel set 22 to drive the wheel set 22 to rotate, thereby driving the pool cleaning robot 100 to move or turn within the pool.

[0053] The housing 10 is provided with an inlet 12 and an outlet 13. A germicidal lamp assembly 60 is disposed at the inlet 12. The germicidal lamp assembly 60 includes a UV germicidal lamp, preferably a UV-C germicidal lamp, meaning the ultraviolet wavelength of this lamp is in the range of 200-280nm, preferably 240-270nm. Ultraviolet light in this wavelength range has excellent disinfection effects, directly destroying the DNA and RNA of cells and viruses, causing microorganisms to die rapidly, and effectively decomposing ozone in the water. Of course, the germicidal lamp assembly 60 may also include other germicidal lamps suitable for underwater operation.

[0054] Specifically, in this embodiment, the germicidal lamp assembly 60 is disposed on the inner wall of one side of the inlet 12 and extends along the length of the inlet 12, preferably such that the entire flow channel of the inlet 12 is within the irradiation range of the germicidal lamp assembly 60. The germicidal lamp assembly 60, disposed on the side wall of the flow channel of the inlet 12, directly sterilizes the water entering the inlet 12, effectively reducing the number of bacteria entering the filter assembly 50.

[0055] Preferably, the inlet 12 is elongated, and the germicidal lamp assembly 60 is also elongated, with the length of the germicidal lamp assembly 60 being approximately equal to the length of the inlet 12, to sufficiently increase the irradiated area of ​​the inlet 12 and improve the sterilization effect. Understandably, in other embodiments, the inlet 12 may also be configured in other shapes, such as arc-shaped or circular. Correspondingly, the germicidal lamp assembly 60 is also preferably configured as an arc or ring shape matching the inlet, in order to maximize the irradiation of the flow channel within the inlet 12 and ensure the sterilization effect.

[0056] like Figure 4 As shown, specifically, the germicidal lamp assembly 60 includes a light source module 62, a base 64, and a lamp cover 66. The base 64 includes a pedestal 642 and a plurality of heat dissipation fins 644 disposed on the surface of the base 642. The base 642 includes a first side and a second side opposite to each other, namely the upper and lower sides in the figure. The light source module 62 is fixed to the first side of the base 642, and the plurality of heat dissipation fins 644 are disposed on the second side of the base 642.

[0057] The light source module 62 includes a substrate 622 and a plurality of LED beads 624 disposed on the substrate 622. In this embodiment, the LED beads 624 are arranged in a straight line along the substrate 622; however, the arrangement of the LED beads 624 is not limited to this. The substrate 622 is attached to the lower surface of the base 642. The LED beads 624 are disposed on the side of the substrate 622 facing away from the base 642. Preferably, thermal paste 65 is coated between the surfaces of the substrate 622 and the base 642, which facilitates the rapid conduction of heat from the substrate 622 to the base 642 of the base 64, and then dissipates the heat through the heat dissipation fins 644. Preferably, the base 64 is made of a metal material with good thermal conductivity, such as aluminum or copper.

[0058] The lampshade 66 is connected to the base 642 of the base 64 to house the light source module 62 and protect its circuitry. Preferably, a sealing ring 68 is provided between the lampshade 66 and the lower surface of the base 642 to seal the light source module 62 and prevent water leakage during underwater operation, which could damage the circuitry of the light source module 62.

[0059] Preferably, the bottom surface of the base 642 is recessed inward to form a receiving cavity 646, in which the light source module 62 is housed. The lampshade 66 is sealed to the base 642, thereby closing the receiving cavity 646 of the base 642, and the receiving cavity 646 is sealed by means of a sealing ring 68.

[0060] In this embodiment, the lampshade 66 is securely fitted around the base 624 of the base 64, preferably in a tight fit. Specifically, the lampshade 66 includes an end wall 665 and side walls 666 extending from the periphery of the end wall 665. For ease of assembly, the lampshade 66 has multiple slots 664 around its periphery. The slots 664 facilitate the slight outward expansion of the edge of the lampshade 66 during assembly, allowing it to be easily fitted around the base 624. Preferably, the area of ​​the lampshade 66 corresponding to the LED bead 624 of the light source module 62 is a light-transmitting area 667, and the material of the light-transmitting area 667 is a transparent material, which is plastic. In this embodiment, the light-transmitting area 667 is located in the middle of the end wall 665, and the light-transmitting area 667 is concave relative to the outer surface of the end wall 665.

[0061] Preferably, a protective film 661 is provided on the light-emitting surface of the light-transmitting area 667 of the lampshade 66, covering the transparent material of the lampshade. Because the surface of the lampshade 66 of the UV lamp assembly 60 often undergoes a curing reaction in swimming pools, over time, a layer of impurities will harden and adhere to the surface, reducing the transmittance of ultraviolet light and affecting the sterilization efficiency. The protective film 661 helps to isolate impurities. During use, the protective film 661 can be replaced periodically, making maintenance convenient.

[0062] In this embodiment, reference Figure 8 The germicidal lamp assembly 60 is installed on the housing 10 via a snap-fit ​​connection. The inner wall of the inlet 12 of the housing 10 has a slot 163, and the end of the side wall 666 of the lamp cover 66 of the germicidal lamp assembly 60 has a hook 668, which protrudes from the base 64. The hook 668 engages with the slot in the housing 10, thereby fixing the germicidal lamp assembly 60 within the flow channel area of ​​the inlet 12. Preferably, the inner wall of the housing 10 also has a groove 162, so that when the germicidal lamp assembly 60 is snapped onto the housing 10, the protruding heat dissipation fins 644 on the germicidal lamp assembly 60 are received within the groove 162 of the housing 10.

[0063] Preferably, a reflective material 161 is provided on the side wall of the inlet 12 opposite to the germicidal lamp assembly 60. This can enhance the sterilization effect and, if the housing 10 is made of plastic, prevent the housing 10 from aging due to prolonged irradiation by the germicidal lamp assembly 60. The reflective material 161 can be a reflective layer directly coated on the bottom wall, or it can be a reflective film, reflective paper, or reflective sheet additionally provided on the side wall, such as aluminum foil.

[0064] Continue to refer to Figures 1-8 In this embodiment, the housing 10 is formed by connecting an upper housing 14 and a lower housing 16, and defines the receiving cavity 11 between the upper housing 14 and the lower housing 16. The water inlet 12 is located at the bottom of the lower housing 16, and the water outlet 13 is located at the upper housing 14. Two water inlets 12 and two water outlets 13 are provided. In this embodiment, the number of water inlets 12 is two, and correspondingly, the number of germicidal lamp assemblies 60 is also two. The two germicidal lamp assemblies 60 are respectively located at the two water inlets 12. Specifically, in this embodiment, the two germicidal lamp assemblies 60 are installed on the sidewall of the same side of the two water inlets 12, that is, the two germicidal lamp assemblies 60 are arranged in parallel, and in this embodiment, the irradiation directions of the two germicidal lamp assemblies 60 are the same. The pump assembly 40 is located within the flow channel of the receiving cavity 11. The pump assembly 40 includes a pump housing 42, a pump motor 44, and an impeller 46. Driven by the pump motor 44, the impeller 46 drives the water flow from the inlet 12, through the flow channel, and out of the outlet 13. The filter assembly 50 is disposed in the flow channel between the inlet 12 and the outlet 13. The filter assembly 50 may include filter paper, mesh, filter screen, or other filter elements, for filtering the water flowing in from the inlet 12 and discharging it to the outlet 13, so that the filtered water can be discharged from the outlet 13.

[0065] In some embodiments, the motor of the drive assembly 30 and the pump motor 44 can be integrated into one unit, or the drive assembly 30 can be used to drive the pump simultaneously. That is, the drive assembly 30 has multiple output shafts, which are respectively used to connect and drive the impellers of the wheel set and the pump assembly.

[0066] A control device 70 is also provided within the receiving cavity 11 of the housing 10. The control device 70 includes a sealed control box, and a power module and a control module disposed within the control box. In this embodiment, the pool cleaning robot 100 is powered by a cable, including a power connection cable 90, which connects the onshore power source to the power module of the control device 70. In other embodiments, the pool cleaning robot 100 may also be wirelessly powered; in the wireless power supply embodiment, the power module includes a rechargeable battery.

[0067] The control device 70 is electrically connected to the pump assembly 40 and the power assembly 20 to supply power to them. In this embodiment, the control device 70 is also electrically connected to the drive assembly 30 to supply power to it, and controls the movement of the walking assembly 21 via the drive assembly 30, thereby controlling the movement direction, speed, etc. of the pool cleaning robot 100. In some embodiments, the pump assembly 40 can also be used to guide the flow and cause fluid jetting to achieve the movement or turning of the auxiliary body. The control device 70 is also electrically connected to the germicidal lamp assembly 60 to supply power to it or to control it.

[0068] Specifically, in this embodiment, the wheel set 22 of the walking assembly 21 includes a pair of driving wheels 222 and a pair of driven wheels 224. The walking assembly 21 also includes two tracks 24 connecting the driving wheels 222 and the driven wheels 224. Each track 24 connects a driving wheel 222 to a corresponding driven wheel 224. The driving wheels 222 are driven to rotate by the drive assembly 30, and drive the driven wheels 224 to rotate synchronously through the tracks 24, thereby realizing the movement of the pool cleaning robot 100. Preferably, in this embodiment, a side plate 26 for covering the walking assembly 21 is also included.

[0069] Preferably, in this embodiment, at least one roller brush 80 is also included, which is generally cylindrical. A plurality of brush blades 82 are provided around its periphery. The roller brush 80 can be fitted onto the axle between the two driving wheels 222 and / or the axle between the two driven wheels 224. Thus, when the pool cleaning robot 100 moves, it drives the roller brush 80 to rotate, and the brush blades 82 simultaneously clean debris and debris from the bottom of the pool.

[0070] Preferably, the roller brush 80 further includes sleeves 84 located at both axial ends. The sleeves 84 are preferably made of an anti-slip material (e.g., sponge) to increase the friction and adhesion between the roller brush 80 and the pool wall, thereby improving the stability of the roller brush 80 rotation.

[0071] As an alternative, such as Figure 10 As shown, the power assembly 20 may also include multiple thrusters 201-204. These thrusters may include at least one first thruster 201 for propelling the pool cleaning robot 100 forward, at least one second thruster 202 for propelling the pool cleaning robot 100 to turn left, and at least one third thruster 203 for propelling the pool cleaning robot 100 to turn right. The movement and turning of the pool cleaning robot 100 within the pool can also be achieved using multiple thrusters 201-204. Preferably, the power assembly 20 may further include at least one fourth thruster 204 for propelling the pool cleaning robot 100 backward.

[0072] Preferably, the top of the upper shell 14 has an opening 140, and a top cover 17 is provided over the opening 140, which can be opened to expose the opening 140. The filter assembly 50 is detachably installed in the receiving cavity 11. During installation or maintenance, the filter assembly 50 can be inserted or removed through the opening 140. The opening 140 facilitates the disassembly, cleaning, or replacement of the filter screen of the filter assembly 50.

[0073] For details, please refer to [link / reference]. Figure 5In this embodiment, the filter assembly 50 is a basket-type filter device, which has a top plate 52, a bottom plate 53, and a sidewall 54 connecting the top plate 52 and the bottom plate 53. The top plate 52, the bottom plate 53, and the sidewall 54 together define the filter chamber 51. The sidewall 54 is a filter screen that surrounds the filter from all sides. The sidewall 54 generally forms a cuboid shape with openings at both the top and bottom. The top plate 52 is connected to the upper end of the sidewall 54 and covers the upper opening, and the bottom plate 53 is connected to the lower end of the sidewall 54 and covers the lower opening. The top plate 52, the bottom plate 53, and the sidewall 54 are detachably connected, for example, by snap-fit ​​connection or by screw connection. Specifically, in this embodiment, a locking block or hook 542 is provided on the outer periphery of the bottom of the side wall 54, and the outer periphery of the bottom plate 53 extends toward the side wall 54 to form a connecting portion 534. The connecting portion 534 has locking holes corresponding to the locking block or hook 542. The locking holes cooperate with the locking block or hook 542 to achieve a snap-fit ​​connection between the side wall 54 and the bottom plate 53. The top plate 52 and the side wall 54 are also connected by the same or similar snap-fit ​​structure, which will not be described in detail here.

[0074] In this embodiment, the top plate 52 of the filter assembly 50 is fixedly connected to the top cover 17 of the housing 10. Preferably, a handle 18 is also connected to the top cover 17. In other embodiments, the top cover 17 is rotatably connected to the upper housing 14 and can be flipped open or closed relative to the upper housing 14. In this case, the filter assembly 50 and the top cover 17 are detachably connected or not fixedly connected, so that the filter assembly 50 can be easily taken out and put in by opening the top cover 17. In some embodiments, the opposing surfaces of the top plate 52 and the top cover 17 of the filter assembly 50 are provided with mutually cooperating positioning structures. Specifically, the surface of the top plate 52 facing the top cover 17 (i.e., the upper surface) is provided with a first positioning part 522, and the surface of the top cover 17 facing the top plate 52 (i.e., the lower surface) is provided with a second positioning part 172. The first positioning part 522 and the second positioning part 172 cooperate with each other so that the top plate 52 and the top cover 17 are aligned before installation. Preferably, the first positioning part 522 of the top plate 52 is a first protrusion, and the second positioning part 172 of the top cover is a second protrusion with a positioning hole. When the top plate 52 and the top cover 17 are aligned, the top end of the first protrusion is engaged in the positioning hole of the second protrusion.

[0075] The bottom end of the filter assembly 50 is detachably abutted against the inner wall of the lower housing 16. The bottom plate 53 of the filter assembly 50 has an inlet 532 corresponding to the water inlet 12 of the housing 10. Preferably, the shape and size of the inlet 532 are adapted to the shape and size of the water inlet 12. The bottom plate 53 also includes a bottom cover 536 that is rotatably opened and closed over the inlet 532. In this embodiment, the two water inlets 12 of the housing 10 include a main water inlet 12 and a secondary water inlet 12. The main water inlet 12 is open during operation, and the secondary water inlet 12 is closed. A counterweight is provided corresponding to the bottom cover 536 of the secondary water inlet 12. When the pool cleaning robot 100 climbs the wall, the bottom cover 536 at the secondary water inlet 12 opens under the action of gravity, thereby opening the secondary water inlet 12. That is, when the pool cleaning robot 100 is climbing the wall, both water inlets 12 open at the same time, increasing the water flow into the flow channel, which in turn increases the water flow at the outlet 13, thereby increasing the counter-thrust force. This allows the pool cleaning robot 100 to firmly adhere to the pool wall for cleaning under the action of the counter-thrust force.

[0076] Preferably, the filter assembly 50 further includes a partition 55 located in the filter chamber 51. The partition 55 is located in the middle of the filter chamber 51, dividing the filter chamber 51 into two parts. The top end of the partition 55 abuts against the top plate 52, and the bottom end of the partition 55 abuts against the bottom plate 53. The arrangement of the partition 55 helps to enhance the filtration effect.

[0077] The germicidal lamp assembly 60 is electrically connected to the control device 70 so that it can be powered and controlled by the control device 70. Therefore, the germicidal lamp assembly 60 is preferably fixedly mounted in the housing 10. The germicidal lamp assembly 60 also includes a power supply cable 67 electrically connected to the light source module 62. The power supply cable 67 can be routed along the inner wall of the housing 10 and connected to the control main board in the control device 70 for power supply and control.

[0078] When the aforementioned pool cleaning robot 100 is in use, the housing 10 moves within the pool via the walking component 21 and its internal drive component 30. Under the action of the pump component 40, water from the pool enters the filter component 50 through the inlet 12, is filtered through the filter screen, and is discharged from the outlet 13, thus achieving the purpose of cleaning the pool water. During this process, the germicidal lamp component 60 continuously irradiates the water in the inlet 12 channel, sterilizing and disinfecting the water before it enters the housing 10 for filtration. This prevents bacteria and contaminants carried in the water from accumulating on the filter component 50 and causing secondary pollution of the water. It also prevents odors caused by excessive bacteria within the filter component 50, reducing the frequency of cleaning and replacement of the filter component 50 and greatly improving the customer experience.

[0079] In this embodiment, the pool cleaning robot 100 is powered by a cable. The cable power supply allows the high-power germicidal lamp to work for a long time, thus ensuring that when sterilizing high-speed flowing water, bacteria in the water can be effectively killed, ensuring the sterilization effect.

[0080] On the other hand, pool cleaning robots are usually accompanied by an electrical control box for power supply or a buoy for enhanced communication. The buoy floats on the water surface and a sterilization lamp assembly 60 can be installed at the bottom of the buoy to sterilize and disinfect part of the water.

[0081] Figure 11-12 A swimming pool cleaning robot according to a second embodiment of the present invention is shown. This embodiment is similar to the first embodiment described above, except for the structure of the germicidal lamp assembly 60. Furthermore, the connection relationships of the germicidal lamp assembly 60 are slightly modified in this embodiment.

[0082] Similar to the above embodiments, the germicidal lamp assembly 60 in this embodiment also includes a light source module 62, a base 64, and a lampshade 66. The light source module 62 is fixed to the lower side of the base 642 of the base 64.

[0083] The light source module 62 includes a substrate 622 and a plurality of LED beads 624 disposed on the substrate 622. In this embodiment, the LED beads 624 are arranged in a matrix along the substrate 622. The substrate 622 is attached to the lower surface of the base 64. The LED beads 624 are disposed on the side of the substrate 622 facing away from the base 64. Thermal paste 65 is coated between the surfaces of the substrate 622 and the base 64, which facilitates the rapid conduction of heat from the substrate 622 to the base 64, thereby dissipating the heat.

[0084] The lampshade 66 is connected to the base 64 and is used to house the light source module 62 within it to protect the circuitry of the light source module 62. Preferably, a sealing ring 68 is provided between the lampshade 66 and the lower surface of the base 64 to seal the light source module 62 and prevent water leakage during underwater operation, which could damage the circuitry of the light source module 62.

[0085] Preferably, the bottom surface of the base 64 is recessed inward to form a receiving cavity 646, and the light source module 62 is housed in the receiving cavity 646.

[0086] The germicidal lamp assembly 60 of this embodiment differs from the germicidal lamp assembly 60 of the first embodiment in that, in this embodiment, the lamp cover 66 is a split structure, including a lamp cover housing 6601 and a light-transmitting plate 6602.

[0087] The lampshade housing 6601 has a light-transmitting opening 6603 in the area corresponding to the light source module 62. The outer edge of the base 64 has multiple fixing holes 645, and the periphery of the lampshade housing 6601 has multiple connecting holes 662, which are threaded holes. During installation, the connecting holes 662 of the lampshade housing 6601 are aligned with the fixing holes 645 of the base 64. Fasteners (such as bolts or screws) can pass through the fixing holes 645 and be threaded into the connecting holes 662, thus tightly clamping the light-transmitting plate 6602 between the lampshade housing 6601 and the base 64.

[0088] Preferably, the base 64 is recessed inward to form a receiving groove 647 on the periphery of its receiving cavity 646, and the sealing ring 68 is received in the receiving groove 647. The light-transmitting plate 6602 presses the sealing ring 68 into the receiving groove 647, thereby sealing the receiving groove 647.

[0089] Similar to the above embodiments, in this embodiment, the area of ​​the lampshade 66 corresponding to the lamp bead 624 of the light source module 62 is a light-transmitting area, namely, the light-transmitting plate 6602 portion. Preferably, the material of the light-transmitting plate 6602 is a transparent material, which can be quartz or glass.

[0090] Figure 13-17 A swimming pool cleaning robot according to a third embodiment of the present invention is shown. This embodiment is similar to the first embodiment, except for the position of the germicidal lamp assembly 60. In this embodiment, only one germicidal lamp assembly 60 is included, and the germicidal lamp assembly 60 is disposed on the inner wall of the top cover 17 of the housing 10. In addition, the structure of the germicidal lamp assembly 60 is also slightly modified in this embodiment.

[0091] Similar to the embodiments described above, the germicidal lamp assembly 60 in this embodiment also includes a light source module 62, a base 64, and a lampshade 66. The base 64 includes a pedestal 642 and a plurality of heat dissipation fins 644 disposed on the upper surface of the pedestal 642. The light source module 62 is fixed to the lower side of the pedestal 642 of the base 64.

[0092] The light source module 62 includes a substrate 622 and a plurality of LED beads 624 disposed on the substrate 622. The substrate 622 is attached to the lower surface of the base 642. The LED beads 624 are disposed on the side of the substrate 622 facing away from the base 642. Thermal paste 65 is applied between the surfaces of the substrate 622 and the base 642, which facilitates the rapid conduction of heat from the substrate 622 to the base 642 of the base 64, and then the heat is dissipated through the heat dissipation fins 644.

[0093] The lampshade 66 is connected to the base 642 of the base 64 to house the light source module 62 and protect its circuitry. Preferably, a sealing ring 68 is provided between the lampshade 66 and the lower surface of the base 642 to seal the light source module 62 and prevent water leakage during underwater operation, which could damage the circuitry of the light source module 62.

[0094] Preferably, the bottom surface of the base 642 is recessed inward to form a receiving cavity 646, in which the light source module 62 is housed. The periphery of the lampshade 66 is connected to the periphery of the bottom surface of the base 642, thereby sealing the receiving cavity 646 of the base 642, and sealing the receiving cavity 646 by means of a sealing ring 68.

[0095] Similar to the above embodiments, in this embodiment, the area of ​​the lampshade 66 corresponding to the LED bead 624 of the light source module 62 is a light-transmitting area 667. The material of the light-transmitting area 667 is a transparent material, which can be quartz, glass, or plastic. Preferably, a protective film 661 is provided on the light-emitting surface of the light-transmitting area 667 of the lampshade 66, covering the transparent material of the lampshade. Because the surface of the lampshade 66 of the UV lamp assembly 60 often undergoes a curing reaction in the swimming pool, after prolonged operation, a layer of impurities will harden and adhere to the surface of the lampshade 66, thereby reducing the transmittance of ultraviolet light and affecting the sterilization efficiency. The protective film 661 helps to isolate impurities. During use, the protective film 661 can be replaced periodically, making maintenance convenient.

[0096] Preferably, a reflective material can be provided on the bottom wall of the housing 10. This can enhance the sterilization effect and, if the housing 10 is made of plastic, prevent the housing 10 from aging due to prolonged irradiation by the germicidal lamp assembly 60. The reflective material can be a reflective layer directly coated on the bottom wall, or it can be a reflective film, reflective paper, or reflective sheet additionally provided on the side wall, such as aluminum foil.

[0097] The germicidal lamp assembly 60 in this embodiment differs from the germicidal lamp assembly 60 in the first embodiment described above in that, in this embodiment, the germicidal lamp assembly 60 is installed in the installation space 19 between the top plate 52 and the top cover 17.

[0098] Preferably, a sealing ring can be provided at the periphery where the top plate 52 of the filter assembly 50 contacts the top cover 17 to form a sealed connection, thereby sealing the installation space 19.

[0099] In some embodiments, the germicidal lamp assembly 60 is embedded in the top plate 52 of the filter assembly 50. Specifically, a through hole 520 is formed in the middle of the top plate 52 corresponding to the lamp cover 66 of the germicidal lamp assembly 60. The lamp cover 66 of the germicidal lamp assembly 60 is fitted into the through hole 520. The light from the light source module 62 passes through the lamp cover 66 and then through the through hole 520 to directly irradiate the filter cavity 51 and the filter screen surrounding the filter cavity 51. Preferably, a limiting structure is provided between the outer periphery of the lamp cover 66 and the wall portion of the top plate 52 defining the through hole 520. Specifically, the limiting structure includes a limiting protrusion 663 provided on the outer periphery of the lamp cover 66 and a limiting groove 521 formed on the wall portion of the top plate 52. The precise positioning of the lamp cover 66 and the top plate 52 is achieved through the cooperation of the limiting protrusion 663 and the limiting groove 521.

[0100] As an example, the base 642 and the lamp cover 66 are connected by fasteners. Specifically, the outer edge of the base 642 is provided with a plurality of fixing holes 645, and the periphery of the lamp cover 66 is provided with a plurality of connecting holes 662. The connecting holes 662 are threaded holes. During installation, the fixing holes 645 of the base 642 and the connecting holes 662 of the lamp cover 66 are aligned, and fasteners (such as bolts or screws) can pass through the fixing holes 645 and be threadedly connected to the connecting holes 662, thereby realizing the assembly of the germicidal lamp assembly 60.

[0101] In this embodiment, the top cover 17 and the top plate 52 of the filter assembly 50 are fixedly connected. In other embodiments, the top cover 17 may not be connected to the top plate 52 of the filter assembly 50, and one side of the top cover 17 may be rotatably connected to the upper shell 14, so that the opening 140 can be flipped open or closed. In this case, the germicidal lamp assembly 60 is preferably fixedly connected to the top cover 17, that is, the germicidal lamp assembly 60 is fixedly connected to the inside of the top cover 17 to facilitate wiring.

[0102] In the pool cleaning robot of this utility model embodiment, since the filter screen is usually not set completely vertically, and on the other hand, the dirt is also accumulated at the bottom of the filter component 50, the light source module 62 can directly irradiate the filter screen and the surface of the dirt, which can fully achieve the purpose of sterilization and disinfection.

[0103] When the aforementioned pool cleaning robot 100 is in use, the housing 10 moves within the pool via the walking component 21 and its internal drive component 30. Under the action of the pump component 40, pool water enters the filter component 50 through the inlet 12, is filtered through the filter screen, and is discharged from the outlet 13, thus achieving the purpose of cleaning the pool water. During this process, the germicidal lamp component 60 continuously irradiates the filter screen and the surface of dirt, sterilizing and disinfecting the filter component and the water filtered by it, preventing secondary pollution of the water, and also preventing odors caused by excessive bacteria within the filter component 50. This reduces the frequency of cleaning and replacement of the filter component 50, greatly improving the customer experience.

[0104] The other components in this embodiment are the same as those in the first embodiment. Please refer to the detailed description of the first embodiment above for details, which will not be repeated here.

[0105] Figure 18-19 A swimming pool cleaning robot according to a fourth embodiment of the present invention is shown. This embodiment is similar to the first embodiment described above, except for the position of the germicidal lamp assembly 60.

[0106] In this embodiment, two germicidal lamp assemblies 60 are also installed on the flow channel sidewalls of the two inlets 12, extending along the length of the inlets 12. This directly sterilizes the water entering the inlets 12, effectively reducing the number of bacteria entering the filter assembly. Understandably, the shape and size of the two germicidal lamp assemblies 60 are adapted to the shape and size of the inlets 12. For example, when the inlets 12 are arc-shaped, the germicidal lamp assemblies 60 are preferably also arc-shaped. When the inlets 12 are circular, the germicidal lamp assemblies 60 are annular.

[0107] Unlike the first embodiment, in this embodiment, two germicidal lamp assemblies 60 are disposed on the sidewall of one side adjacent to the two water inlets 12, and the irradiation directions of the two germicidal lamp assemblies 60 are opposite.

[0108] The specific structures of the housing, filter assembly, germicidal lamp assembly, etc. in this embodiment are the same as those in the above embodiments. Please refer to the detailed description of the first embodiment above, which will not be repeated here.

[0109] Figure 20 A swimming pool cleaning robot according to a fifth embodiment of the present invention is shown. This embodiment is similar to the first embodiment, except for the position of the germicidal lamp assembly 60.

[0110] This embodiment also includes two germicidal lamp assemblies 60, but the two germicidal lamp assemblies 60 are not installed in the flow channel of the water inlet 12, but are arranged on the periphery of the water inlet 12. In this embodiment, the two germicidal lamp assemblies 60 are arranged at intervals, and the two water inlets 12 are located between the two germicidal lamp assemblies 60. Specifically, both germicidal lamp assemblies 60 are installed inside the lower shell 16 facing the inner wall of the upper shell 14. The two germicidal lamp assemblies 60 are adjacent to and directly opposite the bottom of the filter assembly 50, and irradiate the surface of the filter device 50 upward from the bottom of the filter assembly 50.

[0111] The specific structures of the housing, filter assembly, germicidal lamp assembly, etc. in this embodiment are the same as those in the above embodiments. Please refer to the detailed description of the first embodiment above, which will not be repeated here.

[0112] Figure 21 A swimming pool cleaning robot according to a sixth embodiment of the present invention is shown. This embodiment is similar to the fifth embodiment, except for the filter assembly 50.

[0113] In this embodiment, the bottom of the filter assembly 50 includes two impurity collection chambers 56. Impurities and contaminants on the surface of the filter assembly 50 enter the impurity collection chambers 56 from the feed inlet under the influence of gravity or water flow. Preferably, the bottom walls of the two impurity collection chambers 56 are provided as transparent plates 57. Two germicidal lamp assemblies 60 are located on the bottom walls of the two impurity collection chambers 56. The ultraviolet rays from the germicidal lamp assemblies 60 irradiate upwards, passing through the impurity collection chambers 56 and irradiating the filter screen or filter chamber 51.

[0114] The specific structure of the housing, germicidal lamp assembly, etc. in this embodiment is the same as that in the above embodiments. Please refer to the detailed description of the fifth embodiment and the embodiments it refers to above, which will not be repeated here.

[0115] Figure 22 A swimming pool cleaning robot according to a seventh embodiment of the present invention is shown. This embodiment is similar to the sixth embodiment, and the filtration assembly also includes two impurity collection chambers 56, the difference being the position of the germicidal lamp assembly 60.

[0116] Specifically, in this embodiment, two impurity collection chambers 56 are spaced apart, and two germicidal lamp assemblies 60 are disposed in the gap between the two impurity collection chambers 56. Each germicidal lamp assembly 60 is disposed around the impurity collection chamber 56 and irradiates towards the impurity collection chamber 56. The irradiation directions of the two germicidal lamp assemblies 60 are opposite. Preferably, the sidewall of the impurity collection chamber 56 is a transparent plate 57.

[0117] In other embodiments, to facilitate the emptying of impurities and contaminants from the impurity collection chamber 56, a more preferable solution is to mount the germicidal lamp assembly 60 on the inner wall of the lower housing 16. The germicidal lamp assembly 60 directly irradiates the filter screen and the surface of impurities and contaminants of the filter assembly 60 through the transparent plate 57, thus effectively achieving the purpose of sterilization and disinfection.

[0118] The specific structures of the housing, filter assembly, germicidal lamp assembly, etc. in this embodiment are the same as those in the above embodiments. Please refer to the detailed description of the sixth embodiment and the embodiments referenced above, which will not be repeated here.

[0119] Figure 23 A swimming pool cleaning robot according to the eighth embodiment of the present invention is shown. This embodiment is similar to the third embodiment, except that the position of the germicidal lamp assembly 60 is different.

[0120] In this embodiment, the germicidal lamp assembly 60 is disposed on the inner surface of the side wall of the housing 10. The germicidal lamp assembly 60 is adjacent to and directly opposite the side wall 54 of the filter assembly 50. The germicidal lamp assembly 60 directly irradiates the side wall of the filter assembly 50.

[0121] The specific structures of the housing, filter assembly, germicidal lamp assembly, etc. in this embodiment are the same as those in the first, second, or third embodiment. Please refer to the specific description of the third embodiment above, which will not be repeated here.

[0122] Figure 24 A pool cleaning robot according to a ninth embodiment of the present invention is shown. This embodiment is similar to the first embodiment, except that the filter assembly 50 and the germicidal lamp assembly 60 are different.

[0123] In this embodiment, the filter assembly 50 uses a cartridge-type filter element, specifically a cylindrical cartridge. The inlet of the housing 10 is circular, and the bottom of the filter assembly 50 is attached to the inlet 12. Preferably, the filter assembly 50 has an inner cavity 51 at the center of its bottom, with the bottom opening of the inner cavity 51 facing the inlet 12. Under the action of the pump assembly, water flows from the inlet 12 into the inner cavity 51 of the filter assembly 50 and is discharged from the surrounding filter material, flowing towards the outlet 13. In this embodiment, the germicidal lamp assembly 60 is disposed on the inner wall of the lower housing 16, facing the bottom of the filter assembly 50. The germicidal lamp assembly 60 can be a ring-shaped germicidal lamp tube. The ring-shaped germicidal lamp tube surrounds the periphery of the inlet 12, directly radiating to the bottom of the filter assembly 50.

[0124] In other embodiments, the germicidal lamp assembly 60 may also be disposed on top of the filter assembly 50, specifically disposed on the inner wall of the top cover, opposite to the top of the filter assembly 50, with the germicidal lamp assembly 60 directly irradiating the top of the filter assembly.

[0125] As an alternative, the germicidal lamp assembly 60 can also be set on the inner wall of the flow channel. There can be multiple such assemblies arranged at intervals and evenly distributed radially along the filter assembly 50, with the germicidal light directly irradiating the side wall of the filter assembly 50.

[0126] Understandably, in other embodiments, the filter element of the filter assembly 50 may not have an inner cavity, with its bottom fitting against the inlet 12. Under the action of the pump, water flows from the inlet 12 into the filter element of the filter assembly 50 and is discharged from the surrounding filter material. In this case, the entire interior of the cylindrical filter element can be regarded as a filter cavity filled with filter material.

This embodiment is similar to the first embodiment, except that this embodiment includes multiple filter components 50 and the germicidal lamp component 60 may be one or multiple.

[0129] When there is one germicidal lamp assembly 60, it can be placed adjacent to any filter assembly 50, at the water inlet, or in the flow channel upstream of the filter assembly 50. When there are multiple germicidal lamp assemblies 60, they can be placed corresponding to each filter assembly 50, or in the flow channel upstream of each filter assembly 50.

[0130] The specific structures of the housing, filter assembly, germicidal lamp assembly, etc. in this embodiment are the same as those in the first, second, or third embodiment. Please refer to the specific description of the first embodiment above for details, which will not be repeated here.

The germicidal lamp assembly 60 includes a first germicidal lamp assembly 602 and a second germicidal lamp assembly 604. The first germicidal lamp assembly 602 is located at the water inlet 12 inside the housing 10 and is used to radiate water after it enters the housing 10. The second germicidal lamp assembly 604 is located outside the housing 10, specifically embedded in the bottom of the housing 10, and is used to radiate water before it enters the housing 10.

[0132] The specific structures of the housing, the first germicidal lamp assembly, the second germicidal lamp assembly, etc. in this embodiment are the same as those in the first, second, or third embodiments. Please refer to the specific description of the first embodiment above for details, which will not be repeated here.
