Description

Technical Field

[0001] This utility model relates to the field of bioaerosol disinfection, and more specifically, to a toilet seat and a smart disinfection toilet. Background Technology

[0002] Toilets are an important part of modern sanitation systems. However, as a sanitary appliance frequently used in daily life, toilets are very prone to harboring bacteria, viruses, and other microorganisms. For example, pathogenic microorganisms such as Escherichia coli, Staphylococcus aureus, Candida albicans, and even norovirus are commonly found on the surface and inside of toilets. If these pathogenic microorganisms are not removed in time, they can easily generate bioaerosols during flushing and other operations, causing widespread transmission.

[0003] Common toilet sterilization technologies include physical methods (such as high-temperature heating) and chemical methods (such as disinfectants). However, physical and chemical methods are complex and require frequent daily operation, leading to unsatisfactory performance and their gradual phasing out in residential settings. In recent years, short-wave ultraviolet (UV) disinfection technology has emerged. This technology utilizes the short wavelength and high energy of UV light to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, causing cell death and / or regenerative cell death. It offers the dual advantages of being economical and safe.

[0004] While current ultraviolet disinfection toilets have a certain sterilization effect, ultraviolet rays can be harmful to human skin and eyes. If a person is exposed to ultraviolet radiation while using an ultraviolet disinfection toilet, it may cause problems such as skin burns. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figure 1-3The diagram shows a toilet seat provided in this embodiment of the present invention. This toilet seat can be installed onto the toilet body (toilet bowl) and automatically sterilizes the toilet body and the aerosol generated during flushing. The toilet seat in this embodiment includes a seat ring 20, a top cover 30, a disinfection module 40, and a control module 50. The rear ends of the seat ring 20 and the top cover 30 are hinged together and installed together onto the toilet body 10. The seat ring 20 includes an elliptical (including approximate elliptical shapes found in existing toilet seats) toilet opening 21, meaning the main body of the seat ring 20 is an elliptical ring. The disinfection module 40 and the control module 50 are respectively installed on the inner surface of the top cover 30; that is, when the top cover 30 is fastened to the toilet body 10, both the disinfection module 40 and the control module 50 are located on the lower surface of the top cover 30. Similar to existing toilet seats, the aforementioned toilet seat also has a base for connecting and fixing to the toilet body. The base has a mounting shaft, and the tail ends of the seat ring 20 and the top cover 30 are respectively connected and fixed to the mounting shaft. Thus, both the seat ring 20 and the top cover 30 can rotate relative to the toilet body 10 between an open state and a covered state, allowing them to be opened for user use and covered for the toilet body. In practical applications, the seat ring 20, the top cover 30, and their mounting structure to the toilet body 10 can adopt other structures in the art, which will not be elaborated upon here.

[0027] The aforementioned disinfection module 40 includes an annular base 41 and multiple LED beads 42, such as Figure 5 As shown, the shape of the annular base 41 is the same as the shape of the toilet opening 21, that is, the annular base 41 is elliptical or approximately elliptical, and the radial dimension of the outer ring of the annular base 41 is smaller than the radial dimension of the toilet opening 21 on the seat ring 20. That is, when the top cover 30 is fastened to the seat ring 20, on the orthographic projection of the toilet opening 21, the outer edge of the annular base 41 is located inside the inner edge of the toilet opening. Figure 2 As shown. The lower surface of the aforementioned annular base 41 has circumferentially distributed lamp grooves 411, that is, the lamp grooves 411 are also elliptical annular, and the openings of the lamp grooves 411 are located on the lower surface of the annular base 41. In particular, the cross-section of the lamp grooves 411 can be rectangular or triangular, etc. Multiple LED beads 42 are respectively installed in the lamp grooves 411 and are evenly distributed along the circumference of the annular base 41, and the aforementioned LED beads 42 generate light with a wavelength of 240-280nm when working.

[0028] Specifically, to improve disinfection and sterilization performance, the LED beads 42 generate light with a wavelength of 254nm during operation. Specifically, the aforementioned annular base 41 can be made of materials with strong thermal conductivity, such as aluminum alloy, to quickly dissipate the heat generated by the LED beads 42 during operation, thereby extending the service life of the disinfection module 40. Of course, in practical applications, the annular base 41 can also be made of other rigid materials to ensure the distribution pattern of the LED beads 42 on the lower surface of the upper cover 30.

[0029] The control module 50 includes a main control unit 51, an acceleration sensor 52, an infrared sensor 53, and an LED driver unit 54, and the acceleration sensor 52, the infrared sensor 53, and the LED driver unit 54 are electrically connected to the main control unit 51. Those skilled in the art will understand that the main control unit 51, the acceleration sensor 52, the infrared sensor 53, and the LED driver unit 54 can be integrated onto one or more printed circuit boards (PCBs), and the control module 50 may also include a housing for mounting the printed circuit boards.

[0030] The LED driving unit 54 is electrically connected to multiple LED beads 42 of the disinfection module 40 and can drive each LED bead 42 to work, causing it to generate short-wave ultraviolet light. The accelerometer sensor 52 can be a gyroscope sensor, etc. Since the control module is installed on the cover 30, the accelerometer sensor 52 can change its output signal when the state of the cover 30 changes, such as when the cover 30 is lifted or when the cover 30 is closed onto the toilet body 10. The infrared sensor 53 can be a passive infrared sensor. When someone moves within a preset range in front of it, the infrared sensor 53 can receive an infrared signal that is compatible with the human body temperature and generate a corresponding output signal. When the output signal of the accelerometer sensor 52 changes and the infrared sensor does not receive an infrared signal (compatible with the human body temperature), the main control unit 51 outputs a control signal to the LED driving unit 54 to make the LED beads 42 work for a preset time. This preset time can be set in advance as needed, for example, 10-30 minutes.

[0031] In specific implementation, such as Figure 4 As shown, the LED driving unit 54 may include a driving chip U2 (the driving chip U2 and the main control unit 51, for example...) Figure 4 The LED driving unit 54 is connected to chip U1 in the control chip 52, and is connected to each LED bead 42 of the disinfection module 40 through multiple pins of the control chip U2, thereby controlling the operation of each LED bead 42. Those skilled in the art will understand that the LED driving unit 54 can also drive multiple LED beads 42 in any existing manner, such as series connection or group series connection. Furthermore, the main control unit 51, the accelerometer 52, the infrared sensor 53, and their connection methods can all employ conventional techniques in the art, and will not be described in detail here.

[0032] The aforementioned toilet seat uses an accelerometer 52 to detect the toilet's usage status and, based on the detection results from an infrared sensor 53, automatically activates short-wave ultraviolet sterilization. The entire sterilization process requires no manual operation, avoiding harm to the human body from ultraviolet radiation. For example, when the accelerometer 52 detects that the lid 30 is open (e.g., ...), the toilet seat automatically activates short-wave ultraviolet sterilization. Figure 1When the lid 30 is switched to the closed state, because the lid 30 is attached to the toilet body 10, the infrared sensor 53 cannot detect human body temperature. The main control unit 51 controls the LED drive unit 54 to drive the LED beads 42 to emit ultraviolet short waves for 10-20 minutes (this duration can be set in advance) and then automatically turns off to disinfect pathogenic microorganisms on the inner surface of the toilet body. When the acceleration sensor 52 detects that the lid 30 has switched from the closed state to the open state and the infrared sensor 53 has not detected human infrared signals (including the detection of human infrared signals disappearing after a certain period of time, i.e., the lid is opened), the lid will be closed. When 30 people leave (e.g., 30 seconds), the main control unit 51 controls the LED drive unit 54 to drive the LED beads 42 to emit ultraviolet short waves for 10-30 minutes (this duration can be set in advance) and then automatically turn off to eliminate bioaerosols generated by toilet flushing in the space where the toilet is located, ensuring that pathogenic microorganisms in the space are maintained at a low level; when the acceleration sensor 52 detects that the lid 30 is open, and the infrared sensor 53 detects the human infrared signal, the main control unit 51 controls the LED drive unit 54 to keep the LED beads 42 off to avoid burning the human body.

[0033] To improve the sterilization effect on the space between the seat ring 20 and the toilet body 10, such as Figure 5 As shown, in one embodiment of this utility model, the side wall of the lamp groove 411 of the annular base 41 has a first reflective wall 43. The first reflective wall 43 is located inside the LED lamp bead 42 (i.e., on the side closer to the center of the annular base 41), and when the seat ring 20 and the top cover 30 are fastened to the toilet body 10, the vertical angle α1 of the surface of the first reflective wall 43 is 45-60°. In this way, some of the ultraviolet short waves generated by the LED lamp bead 42 when it is working will be reflected by the first reflective wall 43 to the gap between the seat ring 20 and the toilet body 10, avoiding sterilization dead corners.

[0034] Accordingly, when the seat ring 20 and the top cover 30 are fastened to the toilet body 10, the lower edge of the first reflective wall 43 is higher than or level with the bottom of the seat ring 20. Furthermore, those skilled in the art will understand that when the lower edge of the first reflective wall 43 is higher than the bottom of the seat ring 20, the height difference between the lower edge of the first reflective wall 43 and the bottom of the seat ring 20 is preferably within 10mm.

[0035] Specifically, to prevent the shortwave reflections from the first reflective barrier 43 from being blocked, such as... Figure 6 As shown, in one embodiment of the present invention, when the seat ring and the top cover are fastened to the toilet body, on the lower surface of the annular base 41, the portion located inside the light groove 411 (i.e. the side closer to the center of the annular base 41) is higher than the portion located outside the light groove 411 (i.e. the side farther from the center of the annular base 41).

[0036] In one embodiment of the present invention, in order to further improve the utilization rate of shortwave generated by LED beads 42, the side wall of the lamp groove 411 of the annular base 41 has a second reflective wall 44. The second reflective wall 44 is located on the outside of the LED beads 42 (i.e., on the side away from the center of the annular base 41), and when the annular base is fixed to the upper cover 30, the vertical angle α2 of the surface of the second reflective wall 44 is 45-60°.

[0037] In addition, the annular base 41 also includes a transparent cover plate 45, which is sealed at the opening of the lamp slot 411, thereby improving the waterproof performance of the disinfection module 40 and thus extending its service life.

[0038] In one embodiment of this utility model, the width of the annular base 41 can be around 30mm. When the seat ring 20 and the top cover 30 are fastened to the toilet body 10, the distance d1 between the inner side of the front end of the annular base 41 and the front edge of the toilet bowl opening of the seat ring 20 is 85-95mm (the control module 50 can be distributed in this area); the distance d2 between the inner side of the rear end of the annular base 41 and the rear edge of the toilet bowl opening of the seat ring 20 is 45-55mm; and the distance between the inner side of the side of the annular base 41 and the side edge of the toilet bowl opening of the seat ring 20 is 45-55mm. This structure facilitates sufficient ultraviolet radiation and avoids blind spots in the radiation.

[0039] This utility model also provides an intelligent disinfection toilet, including a toilet body and a toilet seat as described above.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
