[0059] Fig. 1-9 shows a pool cleaning robot 100 according to the first embodiment of the present application, which includes 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 sterilization lamp assembly 60 installed in the receiving cavity 11.

[0060] The power assembly 20 is used to provide power to drive the pool cleaning robot 100 to travel in the pool. In the present embodiment, the power assembly 20 includes a walking assembly 21 and a drive assembly 30. The drive assembly 30 can include a drive motor and a reduction gear box. The walking assembly 21 includes a wheel set 22, and the drive assembly 30 is in transmission connection with the wheel set 22 for driving the wheel set 22 to rotate, thereby driving the pool cleaning robot 100 to move or turn in the pool.

[0061] The shell 10 is provided with a water inlet 12 and a water outlet 13. The sterilization lamp assembly 60 is arranged at the water inlet 12. The sterilization lamp assembly 60 comprises a UV sterilization lamp, preferably a UV-C sterilization lamp, i.e. the sterilization lamp has an ultraviolet wavelength of 200-280 nm, preferably 240-270 nm. The ultraviolet light in this wavelength range has excellent sterilization effect, can directly destroy the DNA and RNA of cells and viruses, and make microorganisms die rapidly, and can effectively decompose ozone in water. Of course, the sterilization lamp assembly 50 can also comprise other sterilization lamps suitable for underwater work.

[0062] Specifically, the sterilization lamp assembly 60 of the present embodiment is arranged on the inner wall of the side of the water inlet 12 and extends along the length direction of the water inlet 12, preferably so that the entire flow channel of the water inlet 12 is within the irradiation range of the sterilization lamp assembly 60. The sterilization lamp assembly 60 of the present embodiment is arranged on the side wall of the flow channel of the water inlet 12, directly sterilizes the water entering the water inlet 12, and effectively reduces the number of bacteria entering the filter assembly 50.

[0063] Preferably, the water inlet 12 is in the shape of a long strip, and the sterilization lamp assembly 60 is also in the shape of a long strip, and the length of the sterilization lamp assembly 60 is substantially equal to the length of the water inlet 12, so as to sufficiently increase the irradiation range of the water inlet 12 and improve the sterilization effect. It can be understood that in other embodiments, the water inlet 12 can also be provided in other shapes, such as an arc shape or a circular shape. Correspondingly, the sterilization lamp assembly 60 is preferably arranged in an arc shape or a ring shape matching the water inlet, so as to as far as possible increase the irradiation of the flow channel in the water inlet 12 and ensure the sterilization effect.

[0064] As shown in FIG. 4, specifically, the sterilization lamp assembly 60 comprises a light source module 62, a heat dissipation seat 64 and a lampshade 66. The heat dissipation seat 64 comprises a base 642 and a plurality of heat dissipation fins 644 arranged on the upper side surface of the base 642. The light source module 62 is fixed to the lower side of the base 642 of the heat dissipation seat 64.

[0065] The light source module 62 comprises a substrate 622 and a plurality of lamp beads 624 arranged on the substrate 622. In the present embodiment, the lamp beads 624 are arranged in a straight line along the substrate 622, and it can be understood that the arrangement mode of the lamp beads 624 is not limited thereto. The substrate 622 is attached to the lower side surface of the base 642. The lamp beads 624 are arranged on the side of the substrate 622 away from the base 642. The surfaces of the substrate 622 and the base 642 connected to each other are preferably coated with a heat-conducting paste 65, which is conducive to quickly conducting the heat on the substrate 622 to the base 642 of the heat dissipation seat 64, and then dissipating the heat through the heat dissipation fins 644. Preferably, the heat dissipation seat 64 is made of a metal material with good heat conductivity, such as aluminum, copper, etc.

[0066] The lampshade 66 is connected to the base 642 of the heat sink 64, and is used to cover the light source module 62 to protect the circuit of the light source module 62. Preferably, a sealing ring 68 is arranged between the lampshade 66 and the lower surface of the base 642 to seal the light source module 62 and prevent water from entering the light source module 62 and damaging the circuit of the light source module 62 when the light source module 62 is used underwater.

[0067] Preferably, the bottom surface of the base 642 is inwardly recessed to form a receiving cavity 646, and the light source module 62 is received in the receiving cavity 646. The lampshade 66 is sealingly connected to the base 642 to close the receiving cavity 646 of the base 642 and seal the receiving cavity 646 by means of the sealing ring 68.

[0068] In this embodiment, the lampshade 66 is tightly sleeved on the periphery of the base 624 of the heat sink 64, preferably in a tight fit. Specifically, the lampshade 66 includes an end wall 665 and a side wall 666 extending from the periphery of the end wall 665. To facilitate assembly, the periphery of the lampshade 66 is provided with a plurality of grooves 664, which facilitates the deformation of the edge of the lampshade 66 to slightly expand outwardly during assembly, so that the lampshade 66 can be easily sleeved on the periphery of the base 624. Preferably, the lampshade 66 has a light-transmitting region 667 corresponding to the area of the lamp beads 624 of the light source module 62, and the light-transmitting region 667 is made of transparent material, which can be quartz, glass, or plastic. In this embodiment, the light-transmitting region 667 is located in the middle of the end wall 665, and the light-transmitting region 667 is recessed relative to the outer surface of the end wall 665.

[0069] Preferably, the light-transmitting region 667 of the lampshade 66 is provided with a protective film 661 covering the transparent material of the lampshade. Since the surface of the lampshade 66 of the UV lamp assembly 60 often undergoes solidification reaction in the swimming pool, and the surface of the lampshade 66 hardens and adheres to a layer of impurities after a long period of operation, which reduces the transmittance of ultraviolet light and affects the sterilization efficiency. The protective film 661 is arranged to isolate the impurities. During use, the protective film 661 can be replaced regularly, which is convenient for maintenance.

[0070] In this embodiment, referring to FIG. 8, the sterilization lamp assembly 60 is installed on the shell 10 by means of a snap connection. The inner wall of the water inlet 12 of the shell 10 is provided with a clamping groove 163, and the end of the side wall 666 of the lampshade 66 of the sterilization lamp assembly 60 is provided with a hook 668 protruding from the heat sink 64. The hook 668 is clamped in the clamping groove of the shell 10, so as to fix and install the sterilization lamp assembly 60 in the flow channel region of the water inlet 12. Preferably, the inner wall of the shell 10 is also provided with a recess 162, and when the sterilization lamp assembly 60 is snapped onto the shell 10, the protruding heat dissipation fins 644 of the sterilization lamp assembly 60 are received in the recess 162 of the shell 10.

[0071] Preferably, a reflective material 161 is arranged on the other side wall of the water inlet 12 opposite to the germicidal lamp assembly 60, which can enhance the sterilization effect and avoid the aging of the shell 10 caused by the long-term irradiation of the germicidal lamp assembly 60 in the case that the shell 10 is made of plastic. The reflective material 161 can be a reflective layer directly coated on the bottom wall, or a reflective film, a reflective paper or a reflective sheet, such as a tin foil, attached to the side wall.

[0072] With reference to Figs. 1-8, in the embodiment, the shell 10 is formed by the upper shell 14 and the lower shell 16 connected to each other, and the accommodation cavity 11 is defined between the upper shell 14 and the lower shell 16. The water inlets 12 are arranged at the bottom of the lower shell 16, and the water outlets 13 are arranged at the upper shell 14. Each of the water inlets 12 and the water outlets 13 is provided with two. In the embodiment, the number of the water inlets 12 is two, and correspondingly, the number of the germicidal lamp assemblies 60 is also two. The two germicidal lamp assemblies 60 are arranged at the same side of the two water inlets 12, i.e., the two germicidal lamp assemblies 60 are arranged in parallel, and the irradiation directions of the two germicidal lamp assemblies 60 are the same in the embodiment. The pump assembly 40 is arranged in the flow channel of the accommodation cavity 11. The pump assembly 40 includes a pump shell 42, a pump motor 44 and an impeller 46. Under the drive of the pump motor 44, the impeller 46 drives the water flow to flow into the water inlets 12, and then flows out of the water outlets 13 after passing through the flow channel. The filter assembly 50 is arranged in the flow channel between the water inlets 12 and the water outlets 13. The filter assembly 50 can include filter paper, gauze, filter screen or other filter elements, which are used to filter the water flow flowing into the water inlets 12 and then discharge the filtered water to the water outlets 13 to discharge the filtered water from the water outlets 13.

[0073] In some embodiments, the motor of the drive assembly 30 can be integrated with the pump motor 44, or the drive assembly 30 is used to drive the pump at the same time, i.e., the drive assembly 30 has multiple output shafts which are respectively used to connect and drive the wheels and the impeller of the pump assembly.

[0074] The control device 70 is further arranged in the accommodation cavity 11 of the shell 10. The control device 70 includes a sealed control box, and a power module and a control module arranged in the control box. In the embodiment, the pool cleaning robot 100 is powered by a cable, and includes a power supply connecting cable 90 which connects the power supply on the shore to the power module of the control device 70.

[0075] The control device 70 is electrically connected to the pump assembly 40 and the power assembly 20 for powering the pump assembly 40 and the power assembly 20. In the present embodiment, the control device 70 is electrically connected to the drive assembly 30 for powering the drive assembly 30 and controlling the movement of the travel assembly 21 via the drive assembly 30, thereby controlling the moving direction and speed of the pool cleaning robot 100. In some embodiments, the movement or steering of the pool cleaning robot 100 can also be achieved by means of the pump assembly 40 for directing the flow to cause the fluid to be ejected. The control device 70 is also electrically connected to the germicidal lamp assembly 60 for powering or controlling the germicidal lamp assembly 60.

[0076] In particular, in the present embodiment, the wheel set 22 of the travel assembly 21 includes a pair of driving wheels 222 and a pair of driven wheels 224. The travel assembly 21 further includes two tracks 24 connecting the driving wheels 222 and the driven wheels 224. Each track 24 connects one driving wheel 222 and a corresponding driven wheel 224. The driving wheels 222 are driven to rotate by the drive assembly 30, which in turn drives the driven wheels 224 to rotate synchronously via the tracks 24, thereby enabling the movement of the pool cleaning robot 100. Preferably, the present embodiment further includes side plates 26 for covering the travel assembly 21.

[0077] Preferably, the present embodiment further includes at least one roller brush 80, which is substantially cylindrical. The roller brush 80 has a plurality of brush pieces 82 arranged on the periphery thereof. The roller brush 80 can be sleeved on the axle between the two driving wheels 222 and / or the axle of the two driven wheels 224. Thus, when the pool cleaning robot 100 moves, the roller brush 80 is driven to rotate, and the brush pieces 82 are used to clean the debris on the bottom of the pool synchronously.

[0078] Preferably, the roller brush 80 further includes sleeves 84 at both axial ends thereof. The sleeves 84 are preferably made of non-slip material (e.g., sponge) to increase the friction and adhesion between the roller brush 80 and the wall of the pool, thereby improving the stability of the rotation of the roller brush 80.

[0079] As an alternative, the power assembly 20 can also include a plurality of thrusters 201-204, as shown in FIG. 10. The plurality of thrusters can include at least one first thruster 201 for driving the pool cleaning robot 100 to move forward, at least one second thruster 202 for driving the pool cleaning robot 100 to turn left, and at least one third thruster 203 for driving the pool cleaning robot 100 to turn right. The movement and steering of the pool cleaning robot 100 in the pool can also be achieved by means of the plurality of thrusters 201-204. Preferably, the power assembly 20 can further include at least one fourth thruster 204 for driving the pool cleaning robot 100 to move backward.

The filter assembly 50 is detachably arranged in the receiving cavity 11. During installation or maintenance, the filter assembly 50 can be put in or taken out through the opening 140. By arranging the opening 140, the filter assembly 50 can be easily disassembled, cleaned, or the filter screen replaced.

[0081] Referring to Fig. 5, in the embodiment, the filter assembly 50 is a filter basket type filter device, which has a top plate 52, a bottom plate 53, and a side wall 54 connecting the top plate 52 and the bottom plate 53. The top plate 52, the bottom plate 53, and the side wall 54 jointly define the filter cavity 51. The side wall 54 is a filter screen surrounding the periphery.

Preferably, the first positioning portion 522 of the top plate 52 is a first protruding column, and the second positioning portion 172 of the top cover is a second protruding column with a positioning hole. When the top plate 52 and the top cover 17 are positioned, the top end of the first protruding column is clamped into the positioning hole of the second protruding column.

[0083] The bottom end of the filter assembly 50 is detachably abutted to the inner wall of the lower shell 16. The bottom plate 53 of the filter assembly 50 is provided with an inlet 532 corresponding to the position of the water inlet 12 of the shell 10. Preferably, the shape and size of the inlet 532 are matched with the shape and size of the water inlet 12. The bottom plate 53 further comprises a bottom cover 536 rotatably opened and closed at the inlet 532. In the embodiment, the two water inlets 12 of the shell 10 comprise a main water inlet 12 and a secondary water inlet 12. The main water inlet 12 is opened when working, and the secondary water inlet 12 is closed. The bottom cover 536 corresponding to the secondary water inlet 12 is provided with a counterweight. When the pool cleaning robot 100 climbs the wall, the bottom cover 536 at the secondary water inlet 12 is opened under the action of gravity, thereby opening the secondary water inlet 12, that is, when the pool cleaning robot 100 climbs the wall, the two water inlets 12 are opened at the same time, the water flow entering the flow passage is increased, and the water flow of the water outlet 13 is further increased, thereby increasing the reverse thrust, so that the pool cleaning robot 100 can firmly adhere to the pool wall for cleaning under the action of the reverse thrust.

[0084] Preferably, the filter assembly 50 further comprises a middle partition plate 55 located in the filter cavity 51. The middle partition plate 55 is located in the middle of the filter cavity 51, and divides the filter cavity 51 into two parts. The top end of the middle partition plate 55 is abutted to the top plate 52, and the bottom end of the middle partition plate 55 is abutted to the bottom plate 53. The arrangement of the middle partition plate 55 is beneficial to enhancing the filtering effect.

[0085] The germicidal lamp assembly 60 is electrically connected with the control device 70, so as to be powered and controlled by the control device 70. Therefore, the germicidal lamp assembly 60 is preferably fixedly installed in the shell 10. The germicidal lamp assembly 60 further comprises a power supply cable 67 electrically connected with the light source module 62. The power supply cable 67 is distributed along the inner wall of the shell 10 and is signal connected with the control mainboard in the control device 70, so as to be powered and controlled.

[0086] In use, the shell 10 is walked in the pool by the walking assembly 21 and the driving assembly 30 inside the shell 10. Under the action of the pump assembly 40, the water in the pool enters the filter assembly 50 from the water inlet 12, is filtered by the filter screen and is discharged from the water outlet 13, so as to achieve the purpose of cleaning the water body of the pool. In this process, the germicidal lamp assembly 60 always irradiates the water body in the flow passage of the water inlet 12, so as to sterilize and disinfect the water body before entering the shell 10 for filtering, avoid the secondary pollution of the water by the bacteria carried by the water accumulated on the filter assembly 50, and also avoid the odor caused by too much bacteria in the filter assembly 50, so as to reduce the cleaning and replacement frequency of the filter assembly 50 and greatly improve the customer experience.

[0087] In the embodiment, the pool cleaning robot 100 is cable-powered, which allows the use of high-power germicidal lamps for long-term operation, thereby ensuring that the high-speed flowing water body can be effectively sterilized during operation, ensuring the sterilization effect.

[0088] On the other hand, the pool cleaning robot generally has an electric control box for power supply or a float for communication enhancement. The float floats on the water surface, and the germicidal lamp assembly 60 can be arranged at the bottom of the float to sterilize and disinfect part of the water body.

[0089] Figs. 11-15 show a pool cleaning robot according to a second embodiment of the application. In this embodiment, the difference from the first embodiment is 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 arranged on the inner wall of the top cover 17 of the shell 10. In addition, the structure of the germicidal lamp assembly 60 of this embodiment is also slightly changed.

[0090] Similarly to the above embodiment, the germicidal lamp assembly 60 of this embodiment also includes a light source module 62, a heat sink 64, and a lampshade 66. The heat sink 64 includes a base 642 and a plurality of heat dissipation fins 644 arranged on the upper side surface of the base 642. The light source module 62 is fixed to the lower side of the base 642 of the heat sink 64. The light source module 62 includes a substrate 622 and a plurality of lamp beads 624 arranged on the substrate 622. The substrate 622 is attached to the lower side surface of the base 642. The lamp beads 624 are arranged on the side of the substrate 622 away from the base 642. A heat-conducting paste 65 is coated between the surfaces of the substrate 622 and the base 642, which facilitates the rapid conduction of heat on the substrate 622 to the base 642 of the heat sink 64, and then the heat is dissipated through the heat dissipation fins 644. The lampshade 66 is connected to the base 642 of the heat sink 64, and is used to cover the light source module 62 therein to protect the circuit of the light source module 62. Preferably, a sealing ring 68 is arranged between the lampshade 66 and the lower side surface of the base 642, so as to seal the light source module 62 and avoid water seepage causing damage to the circuit of the light source module 62 during underwater operation.

[0091] Preferably, the bottom surface of the base 642 is inwardly recessed to form a receiving cavity 646, and the light source module 62 is received in the receiving cavity 646. The periphery of the lampshade 66 is connected to the periphery of the bottom surface of the base 642, thereby closing the receiving cavity 646 of the base 642 and sealing the receiving cavity 646 by means of the sealing ring 68.

[0092] Similarly to the above embodiment, the lampshade 66 of the present embodiment has a light-transmitting region 667 corresponding to the region of the light-emitting diodes 624 of the light source module 62, and the material of the light-transmitting region 667 is transparent material, which can be quartz, glass, or plastic. Preferably, the light-transmitting region 667 of the lampshade 66 is provided with a protective film 661 covering the transparent material of the lampshade. Since the surface of the lampshade 66 of the UV lamp assembly 60 often undergoes solidification reaction in the swimming pool, and the surface of the lampshade 66 hardens and adheres to impurities after long working time, thereby reducing the transmittance of ultraviolet light and affecting the sterilization efficiency. The protective film 661 is beneficial to isolate impurities. During use, the protective film 661 can be replaced regularly, which is convenient for maintenance.

[0093] Similarly preferably, the bottom wall of the shell 10 can be provided with a light-reflecting material, which can enhance the sterilization effect, and can avoid the aging of the shell 10 caused by long-term irradiation of the sterilization lamp assembly 60 when the shell 10 is made of plastic. The light-reflecting material can be a light-reflecting layer directly coated on the bottom wall, or a light-reflecting film, light-reflecting paper, or light-reflecting sheet, such as tin foil paper, which is additionally provided on the side wall.

[0094] The sterilization lamp assembly 60 of the present embodiment is different from the sterilization lamp assembly 60 of the above first embodiment in that, in the present embodiment, the sterilization lamp assembly 60 is installed in the installation space 19 between the top plate 52 and the top cover 17.

[0095] Preferably, a sealing ring can be provided on the periphery of the top plate 52 of the filter assembly 50 in contact with the top cover 17 to form airtight connection, thereby sealing the installation space 19.

[0096] In some embodiments, the sterilization 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 lampshade 66 of the sterilization lamp assembly 60, and the lampshade 66 of the sterilization lamp assembly 60 is clamped in the through hole 520, so that the light of the light source module 62 directly irradiates the filter chamber 51 and the filter screen outside the filter chamber 51 after passing through the lampshade 66 and the through hole 520. Preferably, a limiting structure is provided between the periphery of the lampshade 66 and the wall of the through hole 520 defined by the top plate 52. Specifically, the limiting structure includes a limiting protrusion 663 provided on the periphery of the lampshade 66 and a limiting groove 521 formed on the wall of the top plate 52, and the precise positioning of the lampshade 66 and the top plate 52 is achieved by the cooperation of the limiting protrusion 663 and the limiting groove 521.

[0097] As an example, the base 642 is connected with the lampshade 66 by fasteners. Specifically, the peripheral edge of the base 642 is provided with a plurality of fixing holes 645, and the periphery of the lampshade 66 is correspondingly provided with a plurality of connecting holes 662, which are threaded holes. During installation, the fixing holes 645 of the base 642 and the connecting holes 662 of the lampshade 66 are aligned, and fasteners (such as bolts or screws) can be screwed through the fixing holes 645 and the connecting holes 662, thereby achieving assembly of the germicidal lamp assembly 60.

[0098] In the present embodiment, the top cover 17 and the top plate 52 of the filter assembly 50 are relatively fixedly connected. In other embodiments, the top cover 17 can also be not connected with the top plate 52 of the filter assembly 50, and one side of the top cover 17 is rotatably connected with the upper shell 14, so that the opening 140 can be opened or closed by turning over. In this case, the germicidal lamp assembly 60 is preferably relatively fixed with the top cover 17, that is, the germicidal lamp assembly 60 is fixedly connected to the inner side of the top cover 17 to facilitate wiring.

[0099] In the pool cleaning robot of the present embodiment, the filter screen is not usually completely vertically arranged, and on the other hand, the dirt is also accumulated at the bottom of the filter assembly 50. The light source module 62 can directly irradiate the filter screen and the dirt surface, and can fully achieve the purpose of sterilization and disinfection.

[0100] When the above-mentioned pool cleaning robot 100 is in use, the shell 10 is walked in the pool by the walking assembly 21 and the driving assembly 30 inside the shell 10. Under the action of the pump assembly 40, the water in the pool enters the filter assembly 50 from the water inlet 12, is filtered by the filter screen, and is discharged from the water outlet 13, thereby achieving the purpose of cleaning the water body of the pool. In this process, the germicidal lamp assembly 60 always irradiates the filter screen and the dirt surface, sterilizes and disinfects the filter assembly and the water body filtered by the filter assembly, avoids secondary pollution of the water body, and also avoids odor caused by excessive bacteria in the filter assembly 50, thereby reducing the cleaning and replacement frequency of the filter assembly 50 and greatly improving the customer experience.
