[0033] Figure 1-8 A swimming pool cleaning robot 100 according to a first embodiment of the present utility model is shown, comprising a housing 10 having a receiving chamber 11 ; a power assembly 20 connected to the housing 10 ; a germicidal lamp 60 , and a pump assembly 40 and a filter assembly 50 installed in the receiving chamber 11 .

[0034] The power assembly 20 is used to provide power to drive the pool cleaning robot 100 to travel in the pool. In this embodiment, the power assembly 20 includes a walking assembly 21 and a driving assembly 30. The driving assembly 30 may include a driving motor and a reduction gear box. The walking assembly 21 includes a wheel assembly 22, and the driving assembly 30 is connected to the wheel assembly 22 for driving the wheel assembly 22 to rotate, thereby driving the pool cleaning robot 100 to move or turn in the pool.

[0035] The housing 10 is provided with a water inlet 12 and a water outlet 13. The germicidal lamp 60 is arranged at the water inlet 12. The germicidal lamp 60 includes a UV germicidal lamp, preferably a UV-C germicidal lamp, that is, the ultraviolet wavelength of the germicidal lamp is 200-280nm, preferably 240-270nm. The ultraviolet disinfection effect within this wavelength range is excellent, and can directly destroy the DNA and RNA of cells and viruses, causing the microorganisms to die quickly, and can effectively decompose ozone in the water. Of course, the germicidal lamp 50 can also include other germicidal lamps suitable for underwater work.

[0036] Specifically, the germicidal lamp 60 of this embodiment is arranged on the inner wall of one side of the water inlet 12 and extends along the length direction of the water inlet 12, preferably so that the flow channel of the entire water inlet 12 is within the irradiation range of the germicidal lamp 60. The germicidal lamp 60 of this 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.

[0037] Preferably, the water inlet 12 is in the shape of an elongated strip, and the germicidal lamp 60 is also in the shape of an elongated strip, and the length of the germicidal lamp 60 is substantially equal to the length of the water inlet 12, so as to fully increase the range of the water inlet 12 irradiated and improve the sterilization effect. It is understandable that in other embodiments, the water inlet 12 can also be set to other shapes, such as an arc or a circle. Accordingly, the germicidal lamp 60 is also preferably set to an arc or a ring that matches the water inlet, so as to maximize the irradiation of the flow channel in the water inlet 12 and ensure the sterilization effect.

[0038] like Figure 4 As shown, specifically, the germicidal lamp 60 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 sink fins 644 arranged on the upper 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.

[0039] The light source module 62 includes a substrate 622 and a plurality of lamp beads 624 disposed on the substrate 622. In the present embodiment, the lamp balls 624 are arranged in a straight line along the substrate 622. It is understandable that the arrangement of the lamp beads 624 is not limited thereto. The substrate 622 is attached to the lower surface of the base 642. The lamp beads 624 are disposed on the side of the substrate 622 facing away from the base 642. The surface between the substrate 622 and the base 642 connected thereto is preferably coated with a thermal conductive paste 65, which is beneficial for quickly conducting the heat on the substrate 622 to the base 642 of the heat sink 64, and then dissipating the heat through the heat sink fins 644. Preferably, the heat sink 64 is made of a metal material with good thermal conductivity, such as aluminum, copper, etc.

[0040] 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 provided between the lampshade 66 and the lower surface of the base 642 to seal the light source module 62 to prevent water seepage during underwater operation from damaging the circuit of the light source module 62.

[0041] 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 sealedly connected 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.

[0042] In the present embodiment, the lampshade 66 is tightly sleeved on the periphery of the base 624 of the heat sink 64, preferably with 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. For the convenience of assembly, the periphery of the lampshade 66 is provided with a plurality of slots 664, and the provision of the slots 664 is conducive to the deformation of the edge of the lampshade 66 during assembly and slightly expanding outward, so that it can be conveniently sleeved on the periphery of the base 624. Preferably, the area of ​​the lampshade 66 corresponding to the lamp beads 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 can be quartz, glass, or plastic. In the present 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.

[0043] The light-emitting surface of the light-transmitting area 667 of the lampshade 66 is provided with a coating 661, and the coating 661 covers the transparent material of the lampshade. The coating 661 can be torn off and replaced. Since the surface of the lampshade 66 of the UV lamp assembly 60 often undergoes a curing reaction in the swimming pool, a layer of impurities will harden and adhere to the surface of the lampshade 66 after a long working time, thereby reducing the transmittance of ultraviolet rays and affecting the sterilization efficiency. The provision of the coating 661 is conducive to isolating impurities. During use, the coating 661 can be replaced regularly, that is, the old coating can be torn off and a new coating can be attached, which is convenient for maintenance. In this way, the change in the transmittance of the light-transmitting area of ​​the lampshade can be reduced, thereby ensuring the sterilization effect.

[0044] In this embodiment, reference Figure 8 , the germicidal lamp 60 is installed on the housing 10 by means of a snap connection. A snap groove 163 is provided on the inner wall of the water inlet 12 of the housing 10, and a hook 668 is provided at the end of the side wall 666 of the lampshade 66 of the germicidal lamp 60, and the hook 668 protrudes from the heat sink 64. The hook 668 is snapped into the snap groove of the housing 10, so that the germicidal lamp 60 is fixedly installed in the flow channel area of ​​the water inlet 12. Preferably, a groove 162 is also provided on the inner wall of the housing 10, and when the germicidal lamp 60 is snapped on the housing 10, the heat dissipation fins 644 protruding from the germicidal lamp 60 are accommodated in the groove 162 of the housing 10.

[0045] Preferably, a reflective material 161 is provided on the other side wall of the water inlet 12 opposite to the germicidal lamp 60, which can enhance the sterilization effect on the one hand, and prevent the housing 10 from being irradiated by the germicidal lamp 60 for a long time and aging on the other hand when the housing 10 is made of plastic. The reflective material 161 can be a reflective layer directly coated on the bottom wall, or a reflective film, reflective paper or reflective sheet additionally provided on the side wall, such as tin foil.

[0046] Continue to refer Figure 1-Figure 8In this embodiment, the housing 10 is formed by an upper shell 14 and a lower shell 16 connected to each other, and the accommodating chamber 11 is defined between the upper shell 14 and the lower shell 16. The water inlet 12 is arranged at the bottom of the lower shell 16, and the water outlet 13 is arranged at the upper shell 14. Two water inlets 12 and two water outlets 13 are arranged. In this embodiment, the number of water inlets 12 is two, and correspondingly, the number of germicidal lamps 60 is also two. Two germicidal lamps 60 are respectively arranged at the two water inlets 12. Specifically, in this embodiment, the two germicidal lamps 60 are installed on the side wall on the same side of the two water inlets 12, that is, the two germicidal lamps 60 are arranged in parallel, and the irradiation directions of the two germicidal lamps 60 in this embodiment are the same. It can be understood that, as an alternative, the two germicidal lamps 60 can also be arranged on the side wall on the side adjacent to the two water inlets 12, and the irradiation directions of the two germicidal lamps 60 are opposite.

[0047] In other embodiments, the two germicidal lamps 60 may also be disposed at the periphery of the water inlet 12. That is, the two germicidal lamps 60 are disposed at intervals, and the two water inlets 12 are located between the two germicidal lamps 60. The two germicidal lamps 60 are adjacent to and directly facing the bottom of the filter assembly 50, and irradiate the surface of the filter assembly 50 upward from the bottom of the filter assembly 50.

[0048] The pump assembly 40 is disposed in the flow channel of the receiving chamber 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 to flow in from the water inlet 12, and then flows out from the water outlet 13 after passing through the flow channel. The filter assembly 50 is disposed in the flow channel between the water inlet 12 and the water outlet 13. The filter assembly 50 may include filter paper, gauze, filter screen or other filter elements, which are used to filter the water flowing in from the water inlet 12 and then discharge it to the water outlet 13, so as to discharge the filtered water from the water outlet 13.

[0049] In some embodiments, the motor of the drive assembly 30 can be integrated with the pump motor 44, or the drive assembly 30 can be used to drive the pump at the same time, that is, the drive assembly 30 has multiple output shafts, which are respectively used to connect and drive the impeller of the wheel assembly and the pump assembly.

The driving wheel 222 is driven to rotate by the driving assembly 30, and the driven wheels 224 are driven to rotate synchronously through the tracks 24, thereby realizing the movement of the swimming pool cleaning robot 100. Preferably, in this embodiment, a side plate 26 for covering the walking assembly 21 is also included.

[0053] Preferably, in this embodiment, at least one rolling brush 80 is also included, and the rolling brush 80 is roughly cylindrical. A plurality of brush pieces 82 are arranged on its periphery. The rolling brush 80 can be sleeved on the axle between the two driving wheels 222 and / or on the axles of the two driven wheels 224, so that when the swimming pool cleaning robot 100 moves, the rolling brush 80 is driven to rotate, and the brush pieces 82 are used to simultaneously clean the garbage and debris on the bottom of the swimming pool.

[0054] Preferably, the roller brush 80 further includes sleeves 84 at both ends of the roller brush 80. The sleeves 84 are preferably made of anti-slip material (such as sponge) to increase the friction and adhesion between the roller brush 80 and the wall of the swimming pool, and improve the stability of the roller brush 80 rotation.

[0055] As an alternative, the power assembly 20 may also include a plurality of propellers. The plurality of propellers may include at least one first propeller for driving the pool cleaning robot 100 forward, at least one second propeller for driving the pool cleaning robot 100 to turn left, and at least one third propeller for driving the pool cleaning robot 100 to turn right.

[0057] Specific reference Figure 5 In this 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 together define the filter chamber 51. The side wall 54 is a filter screen surrounded on all sides. The side wall 54 is generally enclosed in a rectangular parallelepiped shape with openings at both ends. The top plate 52 is connected to the upper end of the side wall 54 and covers the upper opening, and the bottom plate 53 is connected to the lower end of the side wall 54 and covers the lower opening. The top plate 52, the bottom plate 53 and the side wall 54 are detachably connected, such as by snap connection, or by screw connection. Specifically, in this embodiment, a clamping block or a clamping hook 542 is provided at the periphery of the bottom of the side wall 54, and the periphery of the bottom plate 53 extends toward the side wall 54 to form a connecting portion 534. A clamping hole is provided on the connecting portion 534 corresponding to the clamping block or the clamping hook 542, and the clamping hole cooperates with the clamping block or the clamping hook 542 to realize the buckle connection between the side wall 54 and the bottom plate 53.

[0058] In this embodiment, the top plate 52 of the filter assembly 50 is fixedly connected to the top cover 17 of the housing 10, and 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 shell 14, and can be flipped relative to the upper shell 14 to open or cover the opening 140. 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 conveniently taken in and out by opening the top cover 17. In some embodiments, the top plate 52 of the filter assembly 50 and the top cover 17 facing each other are provided with mutually matching 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 portion 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 portion 172, and the first positioning portion 522 and the second positioning portion 172 cooperate with each other so that the top plate 52 and the top cover 17 are aligned before installation. Preferably, the first positioning portion 522 of the top plate 52 is a first convex column, and the second positioning portion 172 of the top cover is a second convex column with a positioning hole. When the top plate 52 and the top cover 17 are aligned, the top end of the first convex column is inserted into the positioning hole of the second convex column.

[0059] The bottom end of the filter assembly 50 is detachably abutted against the inner wall of the lower shell 16. An inlet 532 is provided at the position of the bottom plate 53 of the filter assembly 50 corresponding to the water inlet 12 of the shell 10. Preferably, the shape and size of the inlet 532 are adapted to the shape and size of the water inlet 12.

In the present embodiment, the two water inlets 12 of the shell 10 include a main water inlet 12 and an auxiliary water inlet 12. The main water inlet 12 is opened during operation, and the auxiliary water inlet 12 is closed. A counterweight is provided at the bottom cover 536 corresponding to the auxiliary water inlet 12. When the swimming pool cleaning robot 100 climbs a 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 swimming pool cleaning robot 100 climbs a wall, the two water inlets 12 are opened at the same time, increasing the water flow entering the flow channel, thereby increasing the water flow at the water outlet 13, thereby increasing the reverse thrust, so that the swimming pool cleaning robot 100 can be firmly attached to the wall of the swimming pool under the action of the reverse thrust for cleaning.

[0060] Preferably, the filter assembly 50 further includes 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, dividing the filter cavity 51 into two. The top end of the middle partition plate 55 abuts against the top plate 52, and the bottom end of the middle partition plate 55 abuts against the bottom plate 53. The provision of the middle partition plate 55 is conducive to enhancing the filtering effect.

[0061] The germicidal lamp 60 is electrically connected to the control device 70 so as to be powered and controlled by the control device 70. Therefore, the germicidal lamp 60 is preferably fixedly installed in the housing 10. The germicidal lamp 60 also includes a power supply cable 67 electrically connected to the light source module 62. The power supply cable 67 can be arranged along the inner wall of the housing 10 and connected to the control main board signal in the control device 70 for power supply and control.

[0062] When the above-mentioned swimming pool cleaning robot 100 is in use, the housing 10 moves in the swimming pool through the walking assembly 21 and the driving assembly 30 therein. Under the action of the pump assembly 40, the water in the swimming pool enters the filter assembly 50 from the water inlet 12, and is discharged from the water outlet 13 after being filtered through the filter screen, thereby achieving the purpose of cleaning the swimming pool water. In this process, the germicidal lamp 60 always irradiates the water in the flow channel of the water inlet 12, sterilizes and disinfects the water before entering the housing 10 for filtration, avoids the accumulation of bacteria and dirt carried in the water on the filter assembly 50 to cause secondary pollution to the water, and also avoids the generation of odor due to excessive bacteria in the filter assembly 50, thereby reducing the frequency of cleaning and replacement of the filter assembly 50, and greatly improving the customer experience.

[0063] In this embodiment, the swimming pool cleaning robot 100 is powered by cables. The cable power supply method allows the use of high-power sterilization lamps to work for a long time, thereby ensuring that when high-speed flowing water is sterilized during operation, bacteria in the water can be effectively killed to ensure the sterilization effect.

[0064] On the other hand, the pool cleaning robot is generally followed by an electric control box for power supply or a buoy for enhancing communication. The buoy floats on the water surface. A sterilizing lamp 60 can be set at the bottom of the buoy to sterilize and disinfect part of the water.

[0065] Figure 9-12 The swimming pool cleaning robot according to the second embodiment of the utility model is shown. This embodiment is similar to the first embodiment, except for the position of the germicidal lamp 60. In this embodiment, only one germicidal lamp 60 is included, and the germicidal lamp 60 is arranged on the inner wall of the top cover 17 of the housing 10. In addition, the structure of the germicidal lamp 60 of this embodiment is also slightly changed.

[0066] Similar to the above-mentioned embodiment, the germicidal lamp 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 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 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 where the substrate 622 and the base 642 are connected are coated with a thermal conductive paste 65, which is conducive to quickly conducting the heat on the substrate 622 to the base 642 of the heat sink 64, and then dissipating the heat 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 provided between the lampshade 66 and the lower surface of the base 642 to seal the light source module 62 and prevent the circuit of the light source module 62 from being damaged due to water seepage when working underwater.

[0067] Preferably, the bottom surface of the base 642 is recessed inward 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 the receiving cavity 646 is sealed by means of a sealing ring 68.

[0068] Similar to the above-mentioned embodiment, the area of ​​the lampshade 66 of the present embodiment corresponding to the lamp 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 can be quartz, glass, or plastic. The light-emitting surface of the light-transmitting area 667 of the lampshade 66 is provided with a coating 661, and the coating 661 covers the transparent material of the lampshade. Because in the swimming pool, the surface of the lampshade 66 of the UV lamp assembly 60 often undergoes a curing reaction, and the surface of the lampshade 66 will harden and adhere to a layer of impurities after a long working time, thereby reducing the transmittance of ultraviolet rays and affecting the sterilization efficiency. The provision of the coating 661 is conducive to isolating impurities. During use, the coating 663 can be replaced regularly for easy maintenance.

[0069] The difference between the germicidal lamp 60 of this embodiment and the germicidal lamp 60 of the first embodiment is that, in this embodiment, the germicidal lamp 60 is installed in the installation space 19 between the top plate 52 and the top cover 17 .

[0070] Preferably, a sealing ring may 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 .

[0071] In some embodiments, the germicidal lamp 60 is embedded in the top plate 52 of the filter assembly 50. Specifically, a through hole 520 is provided in the middle of the top plate 52 corresponding to the lampshade 66 of the germicidal lamp 60, and the lampshade 66 of the germicidal lamp 60 is stuck in the through hole 520. The light of the light source module 62 passes through the lampshade 66 and directly irradiates the filter cavity 51 and the filter screen outside the filter cavity 51 after passing through the through hole 520. Preferably, a limiting structure is provided between the periphery of the lampshade 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 periphery of the lampshade 66 and a limiting groove 521 formed on the wall portion of the top plate 52. The precise positioning of the lampshade 66 and the top plate 52 is achieved through the cooperation of the limiting protrusion 663 and the limiting groove 521.

[0072] As an example, the base 642 is connected to the lampshade 66 by fasteners. Specifically, the outer 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, and the connecting holes 662 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 and 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 60.

[0073] In this 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 may not be connected to the top plate 52 of the filter assembly 50, and one side of the top cover 17 is rotatably connected to the upper shell 14, so that the opening 140 can be turned over to open or close. In this case, the germicidal lamp 60 is preferably relatively fixed to the top cover 17, that is, the germicidal lamp 60 is fixedly connected to the inner side of the top cover 17 for easy wiring.

[0074] In the pool cleaning robot of the embodiment of the utility model, since the filter is usually not arranged completely vertically, and on the other hand, dirt is also accumulated at the bottom of the filter component 50, the light source module 62 can directly irradiate the filter and the surface of the dirt, which can fully achieve the purpose of sterilization and disinfection.

[0075] When the swimming pool cleaning robot 100 is in use, the housing 10 moves in the swimming pool through the walking assembly 21 and the driving assembly 30 therein. Under the action of the pump assembly 40, the water in the swimming pool enters the filter assembly 50 from the water inlet 12, is filtered through the filter screen and then discharged from the water outlet 13, thereby achieving the purpose of cleaning the swimming pool water. During this process, the germicidal lamp 60 always irradiates the filter screen and the surface of the dirt, sterilizes and disinfects the filter assembly and the water being filtered by the filter assembly, avoids secondary pollution of the water, and also avoids the generation of odor due to excessive bacteria in the filter assembly 50, thereby reducing the frequency of cleaning and replacement of the filter assembly 50 and greatly improving the customer experience.

[0076] The other components of this embodiment are the same as those of the first embodiment. Please refer to the above detailed description of the first embodiment for details, which will not be repeated here.

[0077] In other embodiments, the germicidal lamp 60 may also be disposed on the inner surface of the side wall of the housing 10 . The germicidal lamp 60 is adjacent to and directly opposite to the side wall 54 of the filter assembly 50 . The germicidal lamp 60 directly irradiates the side wall of the filter assembly 50 .

[0078] In the above embodiments, the filter components 50 are all basket-type filter devices. As an alternative, a filter element of a filter cartridge type may be used, specifically a cylindrical filter cartridge. The germicidal lamp 60 may be a circular annular germicidal lamp tube. The annular germicidal lamp tube surrounds the periphery of the water inlet 12. Directly radiate the bottom of the filter component 50; or, the germicidal lamp 60 may also be set on the top of the filter component 50, specifically, it may be set on the inner wall of the top cover, opposite to the top of the filter component 50, and the germicidal lamp 60 directly irradiates the top of the filter component.
