Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and more particularly to a spray gun assembly integrating a UVC germicidal lamp and a smart toilet. Background Technology

[0002] The ceramic sink in a toilet bowl easily accumulates dirt and grime after use. A common practice is to use a UV lamp to sterilize it. However, because UV light can be harmful to humans, current methods involve mounting a UV lamp on the toilet seat. The UV light only activates and sterilizes the sink when the user closes the seat. This existing technology has two problems: First, the UV lamp is mounted on the toilet seat, requiring wiring and increasing the high-pressure drive for sterilization, which increases safety risks. Second, the UV lamp is too far from the toilet bowl, necessitating a higher wattage or more lamps to meet sterilization requirements, resulting in higher costs. Summary of the Invention

[0003] The first objective of this invention is to provide a spray gun assembly that integrates a UVC germicidal lamp, which aims to solve the technical problem that the ultraviolet lamps used in existing toilets are installed on the toilet lid at a distance from the bottom wall of the toilet, requiring increased power or number of lamps to meet the sterilization requirements, resulting in high costs.

[0004] To achieve the above objectives, the solution provided by the present invention is as follows:

[0005] An integrated UVC germicidal lamp spray gun assembly includes a UVC germicidal lamp, a spray gun base, a slide, a drive mechanism, and a protective cover.

The mounting part has a through groove adapted to the spray gun seat and an ultraviolet lamp receiving groove communicating with the through groove. The ultraviolet lamp is installed in the ultraviolet lamp receiving groove.

[0010] A second objective of this invention is to provide an intelligent toilet, comprising a toilet body, a rear shell assembly, a seat ring assembly, a lid assembly, a spray gun assembly, and a control assembly. The rear shell assembly is disposed on the toilet body and located at the rear end of the toilet body. The seat ring assembly is hinged to the rear shell assembly. The lid assembly is disposed above the seat ring assembly and is hinged to the rear shell assembly. The spray gun assembly is retractably disposed within the rear shell assembly. The spray gun assembly is an integrated UVC germicidal lamp spray gun assembly as described above. The control assembly is disposed within the rear shell assembly. The seat ring assembly, the lid assembly, the UVC germicidal lamp, and the drive mechanism are respectively connected to the control assembly.

[0011] Preferably, the seat ring assembly includes a seat ring, a second motor, a first shaft, a second shaft, and a human body sensor disposed on the seat ring. The seat ring is symmetrically provided with a first mounting hole and a second mounting hole. A first mounting step is provided on the outer side of the first mounting hole. Two or more first slots are provided circumferentially spaced on the inner wall of the first mounting hole. The first shaft is provided with a first protrusion adapted to the first slot and a first protrusion adapted to the first mounting step. The number of first protrusions is the same as the number of first slots. The first shaft is installed in the first mounting hole. One end of the second shaft is rotatably connected to the rear shell assembly, and the other end is installed in the second mounting hole. The second motor is installed in the rear shell assembly, and the output end of the second motor is connected to the first shaft.

[0012] Preferably, the cover plate assembly includes a cover plate, a third motor, a shaft mounting bracket, a third shaft, and a fourth shaft. The cover plate has symmetrically arranged third and fourth mounting holes. The shaft mounting bracket has an annular portion and a fixing portion. The fixing portion is connected to the rear shell assembly. The third mounting hole has a second mounting step. The inner wall of the third mounting hole has two or more second slots circumferentially. The outer wall of the third shaft has a second protrusion adapted to the second mounting step. The second protrusion has second protrusions circumferentially spaced at intervals, each adapted to a second slot. The number of second protrusions is the same as the number of second slots. The third shaft has an annular slot adapted to the annular portion inside. The third shaft is installed in the third mounting hole and sleeved on the annular portion. The fourth shaft is installed in the fourth mounting hole. The third motor is installed in the rear shell assembly, and the output end of the third motor is connected to the fourth shaft.

[0013] Preferably, the rear shell assembly includes a base plate, a fifth shell mounted on the base plate, and an outer shell mounted on the fifth shell. The outer shell is detachably connected to the fifth shell. The spray gun assembly, the control assembly, the second motor, and the third motor are all installed in the cavity formed by the base plate and the fifth shell. The second shaft is rotatably connected to the fifth shell, and the fixing part is connected to the fifth shell.

[0014] Preferably, the control component includes a main control board, a motor control board, and a microwave detection module. The motor control board, the microwave detection module, and the spray gun assembly are electrically connected to the main control board, and the second motor and the third motor are electrically connected to the motor control board.

[0015] This solution has the following advantages:

[0016] First, the smart toilet is equipped with a retractable spray gun assembly that integrates a UVC germicidal lamp. This assembly satisfies both cleaning and sterilization functions. When the cleaning function or the UVC germicidal lamp is in use, the spray gun assembly is driven by a drive mechanism to extend or retract. When needed, the spray gun assembly extends; when not needed, it retracts. This allows the spray gun assembly to remain within the rear housing when not in use, protecting the UVC germicidal lamp and spray gun assembly from external contamination, thus extending the lifespan of the UVC germicidal lamp and improving the sterilization effect.

[0017] Secondly, the spray gun holder is arc-shaped and has an arc-shaped groove. The slide has an arc-shaped rail that matches the groove, so that the spray gun holder has a downward tilt angle after it is extended. Moreover, the spray gun holder will not tilt excessively after it is extended. While shortening the distance between the UVC sterilizing lamp and the bottom of the toilet body, the UVC sterilizing lamp can still cover the upper part of the toilet body. This allows the UVC sterilizing lamp to cover as much of the toilet body as possible and to sterilize the bottom of the toilet body more thoroughly, improving the sterilization effect. In turn, it can reduce the power or number of UVC sterilizing lamps and reduce costs. Attached Figure Description

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0034] like Figure 1 , Figures 4-6 As shown, this is an embodiment of the present invention, which is an integrated UVC germicidal lamp spray gun assembly installed on a smart toilet and has both cleaning and sterilization functions.

[0035] Please see Figures 4-6 As shown, the spray gun assembly of the integrated UVC germicidal lamp in this embodiment of the invention includes a UVC germicidal lamp 61, a spray gun base 62, a slide base 63, a drive mechanism 64, and a protective cover 65. The protective cover 65 is connected to the front end of the spray gun base 62. The UVC germicidal lamp 61 is installed between the protective cover 65 and the spray gun base 62. The spray gun base 62 is arc-shaped, and the outward end of the spray gun base 62 is lower than the inward end. The spray gun base 62 is provided with an arc-shaped sliding groove 621. The slide base 63 is provided with an arc-shaped sliding rail 634 adapted to the arc-shaped sliding groove 621. The spray gun base 62 and the slide base 63 are slidably connected. The drive mechanism 64 is located on the slide base 63 and is connected to the spray gun base 62, and is used to drive the spray gun base 62 to extend and retract.

[0036] It should be noted that, as Figure 5As shown, in this embodiment, a first cleaning nozzle 623 and a second cleaning nozzle 624 are provided at the top front end of the spray gun holder 62. The water pressure of the first cleaning nozzle 623 can be set to be stronger than that of the second cleaning nozzle 624, thereby enabling the spray gun assembly integrating the UVC germicidal lamp to have multiple cleaning modes, such as massage cleaning mode, gentle cleaning mode, and clean cleaning mode. In massage cleaning mode, the first cleaning nozzle 623 and the second cleaning nozzle 624 are used alternately; in gentle cleaning mode, the second cleaning nozzle 624 is used; and in clean cleaning mode, the first cleaning nozzle 623 is used.

[0037] Specifically, the UVC germicidal lamp 61 is fixed on the spray gun holder 62.

[0038] Optionally, the protective cover 65 is a cover made of quartz glass, which neither affects the sterilization effect of the UVC germicidal lamp 61 nor does it affect the UVC germicidal lamp 61.

[0039] Optionally, the protective cover 65 is snapped into the spray gun holder 62.

[0040] The spray gun assembly of the integrated UVC germicidal lamp in this embodiment of the invention has the following advantages:

[0041] First, the spray gun assembly with integrated UVC germicidal lamp can satisfy both cleaning and sterilization functions.

[0042] Secondly, when the spray gun assembly integrating the UVC germicidal lamp is activated for cleaning or when the UVC germicidal lamp 61 is in use, the drive mechanism 64 drives the spray gun base 62 to extend or retract. When needed, the drive mechanism 64 drives the spray gun base 62 to extend; when not needed, the drive mechanism 64 drives the spray gun base 62 to retract. This ensures that when not in use, the UVC germicidal lamp 61 is located inside the toilet body 10, protecting the UVC germicidal lamp 61 and spray gun base 62 from external contamination, thus extending the service life of the UVC germicidal lamp 61 and improving the sterilization effect.

[0043] Secondly, the spray gun holder 62 is arc-shaped and has an arc-shaped groove 621. The slide 63 has an arc-shaped rail 634 that matches the arc-shaped groove 621. This allows the UVC germicidal lamp 61 to have a downward tilt angle after it is extended, and the spray gun holder 62 will not tilt excessively after it is extended. While shortening the distance between the spray gun holder 62 and the bottom of the toilet body 10, the UVC germicidal lamp 61 can still cover the upper part of the toilet body 10. This allows the UVC germicidal lamp 61 to cover as much of the toilet body 10 as possible and to disinfect the bottom of the toilet body 10 more thoroughly, improving the disinfection effect. This, in turn, can reduce the power or number of UVC germicidal lamps 61 and reduce costs.

[0044] Please see Figures 4-6 As shown, by way of example, in some embodiments, the arc-shaped slide groove 621 is provided at the bottom of the spray gun seat 62, and the arc-shaped slide rail 634 is provided at the top of the slide seat 63. This design allows the UVC germicidal lamp 61 to have a downward tilt angle after it is extended, and also makes the overall structure of the spray gun assembly integrating the UVC germicidal lamp more compact.

[0045] Please see Figures 4-6 As shown, exemplarily, in some embodiments, the drive mechanism 64 includes a first motor 641, a gear 642 connected to the output end of the first motor 641, and a rack 643 meshing with the gear 642 for transmission. The slide block 63 includes a first housing 631 and a second housing 632, which together form a mounting cavity 633. An arc-shaped slide rail 634 is provided on the top of the first housing 631, and a movable groove 6313 is provided on the first housing 631, parallel to the arc-shaped slide rail 634. The movable groove 6313 is located below the arc-shaped slide rail 634 and communicates with the mounting cavity 633. The movable groove 6313 extends to and through the second housing 632. The first motor 641... 41 is installed on the outer wall of the first housing 631. Gear 642 and rack 643 are located in the mounting cavity 633. A first connecting part 6431 is provided on the rack 643. The first connecting part 6431 is located in the movable groove 6313, and both sides of the first connecting part 6431 extend out of the movable groove 6313. The two sides of the inward end of the spray gun base 62 have second connecting parts 622 extending downward. The two ends of the first connecting part 6431 are connected to the second connecting parts 622 on both sides of the spray gun base 62. The drive mechanism 64 is simple, reliable, and easy to control. By reasonably setting the structure of the slide 63 and the connection structure between the drive mechanism 64 and the spray gun base 62, the spray gun assembly integrating the UVC germicidal lamp is more compact as a whole.

[0046] Furthermore, an arc-shaped plate 6311 is provided on the top of the first housing 631 along the extending direction of the first housing 631, and an arc-shaped slide rail 634 is provided on the arc-shaped plate 6311. By providing the arc-shaped plate 6311, the contact area between the spray gun seat 62 and the slide seat 63 can be increased, thereby improving the transmission stability.

[0047] Optionally, the first connecting part 6431 is disposed at the end of the rack 643, so that the transmission distance of the rack 643 is maximized.

[0048] Optionally, the first housing 631 and the second housing 632 are fastened together, which is convenient, simple and reliable, and easy to disassemble.

[0049] Please see Figures 4-6As shown, by way of example, in some embodiments, the first housing 631 is provided with a third connecting part 6312 on the side opposite to the second housing 632, and the second housing 632 is provided with a fourth connecting part (not shown) on the side opposite to the first housing 631. The slide 63 is connected to the rear housing assembly 20 of the smart toilet through the third connecting part 6312 and the fourth connecting part, and the fixing method is simple and reliable.

[0050] Please see Figures 4-6 As shown, by way of example, in some embodiments, the spray gun assembly integrating the UVC germicidal lamp further includes an ultraviolet lamp 66. The slide 63 has an outward-facing mounting part 635. The mounting part 635 has a through groove 6351 adapted to the spray gun holder 62 and an ultraviolet lamp receiving groove 6352 communicating with the through groove 6351. The ultraviolet lamp 66 is installed in the ultraviolet lamp receiving groove 6352. When the spray gun holder 62 is retracted, the protective cover 65 is located below the ultraviolet lamp 66. The ultraviolet lamp 66 sterilizes and disinfects the protective cover 65 and the spray gun holder 62, making it more hygienic.

[0051] In this embodiment, the through groove 6351 is arranged horizontally along the mounting portion 635, and the ultraviolet lamp receiving groove 6352 is arranged vertically along the mounting portion 635.

[0052] Optionally, the mounting part 635 is disposed on the top of the slide 63.

[0053] Please see Figures 1-6 As shown, this embodiment of the invention also provides a smart toilet, including a toilet body 10, a rear shell assembly 20, a seat ring assembly 30, a lid assembly 40, a spray gun assembly 60, and a control assembly 70. The rear shell assembly 20 is disposed on the toilet body 10 and located at the rear end of the toilet body 10. The seat ring assembly 30 is hinged to the rear shell assembly 20. The lid assembly 40 is disposed above the seat ring assembly 30 and is hinged to the rear shell assembly 20. The spray gun assembly 60 is retractably disposed within the rear shell assembly 20. The spray gun assembly 60 adopts the above-mentioned spray gun assembly with integrated UVC germicidal lamp. The control assembly 70 is disposed within the rear shell assembly 20. The seat ring assembly 30, the lid assembly 40, the UVC germicidal lamp 61, and the drive mechanism 64 are respectively connected to the control assembly 70.

[0054] In this embodiment, a flushing assembly is integrated inside the toilet body 10. The flushing assembly is connected to the control assembly 70. The flushing assembly adopts a conventional flushing structure, which will not be described in detail.

[0055] The working principle of the smart toilet in this embodiment of the invention is as follows:

[0056] When the control component 70 detects a person within a preset distance outside the toilet body 10, it controls the lid assembly 40 to open for user convenience.

[0057] When the seat ring assembly 30 detects that the user has left the seat ring assembly 30, the control assembly 70 controls the seat ring assembly 30 to open, and then controls the flushing assembly to flush the toilet body 10. After flushing, the control assembly 70 controls the seat ring assembly 30 and the lid assembly 40 to close, and then controls the drive mechanism 64 to drive the spray gun seat 62 to extend and turn on the UVC sterilization lamp 61. The UVC sterilization lamp 61 sterilizes and disinfects the toilet body 10. The sterilization and disinfection time can be preset. After sterilization and disinfection is completed, the UVC sterilization lamp 61 is turned off, and the drive mechanism 64 is controlled to drive the spray gun seat 62 to retract into the rear shell assembly 20.

[0058] The smart toilet of this invention has the following advantages:

[0059] First, the smart toilet is equipped with a retractable spray gun assembly with an integrated UVC sterilization lamp, which can satisfy both cleaning and sterilization functions. When the spray gun assembly 60 is activated for cleaning or the UVC sterilization lamp 61 is in use, the spray gun base 62 is extended or retracted by the drive mechanism 64. When needed, the spray gun base 62 is extended by the drive mechanism 64, and when not needed, the spray gun base 62 is retracted by the drive mechanism 64. In this way, when not in use, the UVC sterilization lamp 61 is located inside the rear shell assembly 20, which protects the UVC sterilization lamp 61 from external contamination, thereby improving the service life of the UVC sterilization lamp 61 and enhancing the sterilization effect.

[0060] Secondly, the spray gun holder 62 is arc-shaped and has an arc-shaped groove 621. The slide 63 has an arc-shaped slide rail 634 that matches the arc-shaped groove 621. This allows the spray gun holder 62 to have a downward tilt angle after it is extended, and it does not tilt excessively after it is extended. While shortening the distance between the UVC sterilizing lamp 61 and the bottom of the toilet body 10, the UVC sterilizing lamp 61 can still cover the upper part of the toilet body 10. This allows the sterilization and disinfection range of the UVC sterilizing lamp 61 to cover as much of the toilet body 10 as possible, and to sterilize and disinfect the bottom of the toilet body 10 more thoroughly, improving the sterilization and disinfection effect. This, in turn, reduces the power or number of UVC sterilizing lamps 61, thus reducing costs.

[0061] Please see Figure 1 , Figure 3 , Figure 7 and Figure 8As shown, exemplarily, in some embodiments, the seat ring assembly 30 includes a seat ring 31, a second motor 32, and a human body sensor 35 disposed on the seat ring 31. The seat ring 31 is hinged to the rear shell assembly 20. The second motor 32 is installed inside the rear shell assembly 20 and is connected to the seat ring 31, and is used to drive the seat ring 31 to open and close. The human body sensor 35 is used to detect whether the user is using or leaving. The seat ring 31 is driven to open and close by the second motor 32. The structure is simple and the control is convenient.

[0062] Furthermore, the seat ring 31 is symmetrically provided with a first mounting hole 311 and a second mounting hole 312. The outer side of the first mounting hole 311 is provided with a first mounting step 3111. The inner wall of the first mounting hole 311 is provided with two or more first slots 3112 spaced apart circumferentially. The seat ring assembly 30 also includes a first shaft 33 and a second shaft 34. The first shaft 33 is provided with a first protrusion 331 that matches the first slot 3112 and a first protrusion 332 that matches the first mounting step 3111. The number of first protrusions 331 is the same as the number of first slots 3112. The first shaft 33 is installed in the first mounting hole 311. One end of the second shaft 34 is rotatably connected to the rear shell assembly 20, and the other end is installed in the second mounting hole 312. The output end of the second motor 32 is connected to the first shaft 33. By reasonably setting the structure of the seat ring assembly 30, the connection between the second motor 32 and the seat ring 31 is more stable and easier to assemble.

[0063] Optionally, the seat ring 31 includes a third housing 313 and a fourth housing 314 detachably connected to the third housing 313. The human body sensor 35 is installed between the third housing 313 and the fourth housing 314. The third housing 313 is provided with the first mounting hole 311 and the second mounting hole 312. This design allows the human body sensor 35 to be installed inside the third housing 313 and the fourth housing 314, thus protecting the human body sensor 35.

[0064] In this embodiment, the third housing 313 and the fourth housing 314 are snapped together for easy loading and unloading.

[0065] Please see Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, by way of example, in some embodiments, the cover plate assembly 40 includes a cover plate 41 and a third motor 42. The cover plate 41 is hinged to the rear shell assembly 20. The third motor 42 is installed inside the rear shell assembly 20 and is connected to the cover plate 41. The third motor 42 is used to drive the cover plate 41 to open and close. The cover plate 41 is driven to open and close by the third motor 42. The structure is simple and the control is convenient.

[0066] Furthermore, the cover plate 41 is symmetrically provided with a third mounting hole 411 and a fourth mounting hole 412. The cover plate assembly 40 also includes a shaft mounting bracket 43, a third shaft 44, and a fourth shaft 45. The shaft mounting bracket 43 is provided with an annular portion 431 and a fixing portion 432. The fixing portion 432 is connected to the rear shell assembly 20.
