Title: Auto cleaning toilet seat assembly

Description:
FIELD OF THE INVENTION 
     The present invention relates to toilet seat cleaning, disinfecting, sterilizing, and/or sanitizing systems, and more particularly, to an assembly for automatically cleaning, disinfecting, sterilizing, and/or sanitizing a toilet seat. 
     BACKGROUND OF THE INVENTION 
     There are many other known toilet seat washing assemblies. Most of these assemblies employ the use of numerous components in order to function properly. These numerous components require a great deal of user time spent in maintenance and installation. Moreover, many of these assemblies have components that rotate and move when in operation such that they are more susceptible to failure. Not only are these assemblies more susceptible to failure, they are also more expensive and difficult to manipulate for precise control of the assembly during the cleaning process. For example, some known assemblies have rotating arms that clean the toilet seat but these arms are not able to be controlled or optimized to produce various cleaning cycles desirable for a particular user. The use of additional components by these known assemblies also make them generally expensive for most users and/or other consumers, and require more time/cost to install and to maintain. 
     Additionally, many known toilet seat cleaning assemblies are not capable of, or are not configured properly to, effectively and efficiently clean and/or sanitize toilet seats that are completely circular. Specifically, some known toilet seat cleaning assemblies are designed to sequential emit a cleaning solution around a toilet seat that is then designed to run off into the toilet bowl. These systems, however, often leave residue from the cleaning solution and/or require the emission of significant amounts of fluid. As such, the toilet seat is disadvantageously not immediately ready for use by the user and/or is not economical. Additionally, many known toilet seat cleaning assemblies are designed to work solely with one type of (e.g., u-shaped) toilet seats, thereby making said assemblies ineffective or impracticable for use with other types (e.g., circular) toilet seats. 
     To overcome these drawbacks, it is therefore desired to have an improved auto cleaning toilet seat assembly capable of effectively and efficiently cleaning, disinfecting, sterilizing, and/or sanitizing toilet seats. 
     SUMMARY OF THE INVENTION 
     This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. 
     The present invention generally relates to an improved auto cleaning toilet seat assembly capable of effectively and efficiently cleaning, disinfecting, sterilizing, and/or sanitizing toilet seats. In particular, the auto cleaning toilet seat assembly according to the present invention is capable of reducing (or even destroying) microbial activity or microorganisms on a surface of the toilet, thereby performing an effective disinfecting, sterilizing, or sanitizing function. 
     One aspect of the present invention provides a toilet seat assembly for a toilet having a toilet bowl with a top surface, the toilet seat assembly comprising: a base configured to be secured to the top surface of the toilet bowl; a toilet seat attached to the base and movable between an open position and a closed position; and a cover attached to the base and movable between an open position and a closed position. The cover has a front end a rear end and, when at its closed position, substantially cover the toilet seat. The toilet seat assembly comprises a liquid discharge and disperse means, which further comprises one or more liquid discharge apertures for discharging a liquid, and one or more gas discharge apertures for facilitating dispersal of the liquid (e.g., sanitizing mist injection) in desired direction(s) (e.g., from to the rear end to the front end, from top to bottom, and/or other directions), thereby enabling the liquid to contact, clean, disinfect, sterilize, and/or sanitize the toilet seat (e.g., all areas of the toilet seat) and/or the toilet bowl. 
     In some embodiments, the liquid discharge and disperse means comprises an atomizer, a nebulizer, a vaporizer, an electrostatic sprayer, or any other suitable type of sprayer or injector. 
     In some embodiments, the liquid is discharged in a form of mist. 
     In some embodiments, the liquid discharge and disperse means comprises at least one atomizer for spraying the mist from the one or more liquid discharge apertures (e.g., in any desired direction). 
     In some embodiments, at least one atomizer is an ultrasonic mist atomizer (also called ultrasonic mist maker or humidifier). In some embodiments, the ultrasonic mist atomizer may include a piezo atomizer transducer for transporting high-frequency sound waves into a mechanical energy that is transferred into the liquid, thereby creating the mist. For instance, the ultrasonic mist atomizer may include a piezo atomizer transducer such as disc/nozzle (ceramic humidifier), which works by transposing high-frequency sound waves into mechanical energy that is transferred into a liquid, creating standing waves. As the liquid exits the atomizing surface of the disc, it&#39;s broken into a fine mist of uniform micron-sized droplets. 
     In some embodiments, the mist is discharged in one or more directions. The mist can be discharged from any direction. Examples of such directions may include but are not limited to: from the rear to front, and/or from top to bottom. 
     In some embodiments, at least part of the liquid discharge and disperse means is located at or close to the base, the cover or toilet seat. 
     In some embodiments, the liquid discharge and disperse means comprises one or more liquid or gas discharge apertures configured for discharging or facilitating dispersal of the liquid from behind the cover, from the cover, from the toilet seat, and/or from the base. 
     In some embodiments, the base can be short or long. For instance, the base can be extended (e.g., optionally with an extension) to encompass or over at least part or even the entirety of the toilet bowl. The liquid (e.g., mist) may be injected from the base (or its extension). 
     In some embodiments, the liquid discharge and disperse means optionally may include one or more fans for dispersing and inducing the mist. 
     In some embodiments, the gas is discharged at a predetermined time after the discharge of liquid. 
     In some embodiments, the toilet seat assembly includes a deodorizing substance (e.g., deodorizing oil), which can be either included by the liquid, or sprayed by a deodorizing spray (e.g., located below the toilet cover or toilet seat) into the toilet bowl (e.g., in any suitable direction). 
     In some embodiments, the toilet seat assembly comprises an electrical system operably configured to control the discharge and dispersal of liquid or deodorizing substance (e.g., deodorizing oil), and/or movement of the cover between open and closed positions. 
     In some embodiments, at least one (or both) of the cover and the toilet seat is removably attached to the base. 
     In some embodiments, the base is a universal design capable of fitting or being mounted onto a variety/all types of toilet structures, and capable of removably receiving and attaching different types, sizes, or shapes of cover and/or toilet seat (e.g., both U-shaped and circular toilet seats), thereby being able to adapt to different toilet bowl/seat designs. 
     In some embodiments, the base comprises the electrical system, at least part of the liquid discharge and disperse means, and/or a liquid storage unit. 
     In some embodiments, the toilet seat assembly further comprises a flushing control mechanism to ensure that the cover is closed when the toilet is flushed, in order to prevent undesired spread of germs. Such flushing control mechanism may be configured to control the movement of the cover by an electrical means, mechanical means, or combination thereof. 
     In some embodiments, the toilet seat assembly further comprises a wireless or wired communication system configured to collect data and/or inform status. 
     In some embodiments, the toilet seat assembly comprises a digital display configured to display the status and/or process of the cleaning, disinfecting, sterilizing, and/or sanitizing of the toilet seat, battery life, amount of disinfectant, and/or errors. 
     In some embodiments, the toilet seat assembly comprises a triggering mechanism configured for triggering the cleaning, disinfecting, sterilizing, and/or sanitizing procedure by a user. Such a triggering mechanism may include a mechanical means, electrical means, or a combination thereof. For instance, the triggering mechanism may include a sensor (e.g., IR sensor) for triggering the cleaning, disinfecting, sterilizing, and/or sanitizing procedure. 
     In some embodiments, the cover further comprises an upper wall; an outer sidewall extending downwardly from the edge of the upper wall; and an inner sidewall extending downwardly from bottom surface of the upper wall, wherein the outer and inner sidewalls at least partly oppose one another, and form part of a transport conduit configured to facilitate the dispersal of the liquid along the transport conduit. 
     In some alternative embodiments, the cover comprises an upper wall and optionally an outer sidewall extending downwardly from the edge of the upper wall, wherein the upper wall has a substantially flat bottom surface (e.g., without inner sidewall or conduit surrounding the inside perimeter of the toilet seat). 
     In some embodiments, the toilet seat assembly includes one or more of the following additional components: UVC disinfection light, solar panel for extension of battery life, medical testing device, dynamo on the water line to generate battery charge, bidet , seat warmer, night light, radio/music device, advertising, mini projector, air dryer for the seat and/or the user, AI system, voice command unit, user customization or memory settings, adjustable children seat, automatic seat closing and flushing control, massage device, remote control means, men kick and flush means, dual filtration, touch-free flush means, anti-stick surface, antimicrobial surface, fire retardant materials, UVC disinfection, Wi-Fi connectivity, Bluetooth connectivity or other wireless communication means, odor mitigation unit, unit for adjusting toilet height, and safety unit. 
     In some embodiments, the medical testing device is configured to conduct one or more medical studies. Examples of the medical applications or studies may include but are not limited to urine tests, dermatology, stool tests, weight measurements, blood pressure tests, and diabetes tests. 
     In some embodiments, the safe unit is configured to provide one or more the following functions: waterproof and moisture proof, fire protection, leak protection, over current protection, antifreeze protection, and short circuit protection. 
     In some embodiments, the toilet seat assembly is operated by one or more energy sources selected from the group consisting of batter power, kinetic energy, solar energy, mechanical energy, energy created by biodegradation, electric energy, recyclable or green energy, and smart power/energy saving means. 
     Another aspect of the present invention provides use of an atomizer (e.g., ultrasonic mist atomizer or other types of atomizers) in a delivery system for disinfecting a surface, wherein the surface remains substantially dry after getting a disinfection by the atomizer. This is significantly different from conventional sprays for disinfecting a surface (which result in wet surface after the disinfection)—and thus provides advanced features and convenience. 
     In some embodiments, the surface comprises a hard surface in the bathroom or kitchen, such as in a sink or toilet. 
     In some embodiments, the delivery system is included by a toilet seat assembly, such as the toilet seat assembly described above. 
     As used herein, the term “clean” or “cleaning” refers to a process to facilitate or aid in soil removal, bleaching, microbial population reduction, and any combination thereof. 
     As used herein, the term “sanitize” or “sanitizing” refers to reductions in microbial activity on a surface. A sanitizing process may include at least partially reducing the number of microorganisms as well as substantially reducing the number of microorganisms. In some embodiments, sanitization includes sterilization, e.g., where all microorganisms or all desired microorganisms are destroyed. As used herein, the term “microorganism” refers to any noncellular or unicellular (including colonial) organism. Microorganisms include all prokaryotes. Microorganisms include bacteria (including cyanobacteria), spores, lichens, fungi, protozoa, virinos, viroids, viruses, phages, and some algae. 
     As used herein, the term “or” is meant to include both “and” and “or.” In other words, the term “or” may also be replaced with “and/or.” 
     As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. 
     As used herein, the spatially relative terms, such as “top”, “bottom”, “inside”, “outside”, “above”, and “under” may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. Similarly, the terms “vertical” and “horizonal” and the like are used for the purpose of explanation only unless specifically indicated. The terms are not intended to require the described elements or structures in a specific direction, and are not intended to limit the scope of this invention as such.

     DETAILED DESCRIPTION OF THE INVENTION 
     Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that they are not intended to limit the invention to these embodiments. To the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the claims. Furthermore, in the detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be obvious to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well known methods, procedures, components, and other features have not been described in detail as not to unnecessarily obscure aspects of the present auto cleaning toilet seat assembly. 
     Generally speaking, various embodiments of the present invention provide for an improved auto cleaning toilet seat assembly capable of effectively and efficiently cleaning, disinfecting, sterilizing, and/or sanitizing toilet seats. Set forth below are several illustrations or examples of apparatus of this invention containing auto cleaning toilet seat. 
     Referring now to  FIGS.  1 - 9    and utilizing the incorporated disclosure referenced above, one embodiment of the present invention is shown.  FIGS.  1 - 9    show several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. 
       FIGS.  1 - 8    shows toilet seat assembly  100  which includes base  102  to be secured to the top surface of the toilet bowl (e.g., through a securing and attaching assembly  103  as shown in  FIG.  6   ). Toilet seat  104  and cover  106  are attached (e.g., pivotally) to base  102 . The toilet seat  104  and/or cover  106  can be removably attached to the base. For instance, the base  102  may be a universal design/module capable of fitting or being mounted onto a variety types of toilet structures, and capable of removably receiving and attaching different types, sizes, or shapes of cover and/or toilet seat (e.g., both U-shaped and circular toilet seats). Both the toilet seat  104  and the cover  106  are movable/rotatable between their respective open and closed positions (e.g., as shown in  FIGS.  6 ,  8   , and  9 , which illustrate the toilet seat assembly with its cover opened). When the cover  106  is closed, it substantially covers the toilet seat  104  (e.g., with the outer sidewall  108  of the cover substantially surrounding, contouring and/or adjoining the outer circumference surface  110  of the toilet seat). The toilet seat assembly according to the present invention may also include a flushing control mechanism to ensure that the cover is put down or completely closed when the toilet is flushed, in order to prevent undesired spread of germs, e.g., by electrical means, mechanical or other means. 
     As shown in  FIGS.  1  and  8   , toilet seat assembly  100  may include one or more liquid discharge apertures  112  for discharging a liquid (e.g., with sprayer or atomizer configured for spraying a mist), and one or more gas discharge apertures  114  (e.g., optionally with fans) for facilitating dispersal of the liquid, generally in a direction from to the rear end to the front end. Accordingly, the liquid is dispersed throughout the toilet seat  104  (e.g., all areas of the toilet seat  104  including its top surface  116 , inner circumference surface  118  and outer circumference surface  110 ), as well as the toilet bowl area, thereby cleaning, disinfecting, sterilizing, and/or sanitizing the toilet seat and toilet bowl. Particularly, there may be one or multiple discharge apertures (or entries), configured for discharging or facilitating dispersal of the liquid from the same or different locations (e.g., behind the cover, from the cover, from the toilet seat, and/or from the base). The liquid discharge according to the present invention may be atomized liquid spray of water, disinfectant, a combination of water and/or disinfectant, or other liquid. It is also to be understood that, according to the present invention, the liquid (e.g., sanitizing mist) may be discharged in any other desired direction(s), including, e.g., from top to bottom. 
     In some embodiments, the cover  106  is designed to form a transport conduit  120  to facilitate the dispersal of the liquid along the transport conduit. For instance, as shown in  FIGS.  8  and  9   , the cover  106  may include an upper wall  122 ; an outer sidewall  108  extending downwardly from the edge of the upper wall; and an inner sidewall  124  extending downwardly from bottom surface of the upper wall. The outer and inner sidewalls at least partly oppose one another. When the cover is closed, the outer sidewall of the cover is configured for substantially surrounding, contouring and/or adjoining the outer circumference surface of the toilet seat. In some embodiments, the inner sidewall  124  of the cover is shaped corresponding to (but smaller than) the inner circumference surface of the toilet seat. For instance, when the cover is closed, the inner sidewall  124  of the cover may be located in proximity to and generally surrounded by the inner circumference surface  118  of the toilet seat. Accordingly, part of the upper wall  122 , the outer and inner sidewalls ( 108 ,  124 ) of the cover, and a portion of the toilet seat form a transport conduit, along which liquid and/or gas are guided to flow as desired, thereby ensuring that important parts of the toilet seat are effectively reached and cleaned. 
     In some other embodiments, the bottom surface of the upper wall of the cover can be generally flat (like the conventional toilet seat covers). For instance, as shown in  FIG.  9   , cover  126  can have a generally flat bottom/inner surface  128  for its upper wall, without any inner sidewall (or conduit) surrounding the inside perimeter of the toilet seat. 
     The toilet seat assembly may include an electrical system to control the discharge and dispersal function, the cleaning, disinfecting, sterilizing, and/or sanitizing process, and the movement of the cover. In some embodiments, the electrical system is located in a universal base, which removably receives the attached toilet seat and cover. Accordingly, a user can easily change or replace the toilet seat and cover that are attached to the base, in order to adapt the base (as well as its electrical system and liquid discharge and disperse system) to different toilet seat/bowl designs as desired. 
     The toilet seat assembly according to the present invention may also include a wireless or wired communication system configured to collect data and/or inform status (e.g., status and/or process of the cleaning, disinfecting, sterilizing, and/or sanitizing of the toilet seat, battery life, amount of disinfectant, and/or errors). Moreover, the toilet seat assembly according to the present invention may include additional components, such as a deodorizing spray for spraying a deodorizing substance (e.g., deodorizing oil) into the toilet bowl, UVC disinfection light, solar panel for extension of battery life, medical testing device, dynamo on the water line to generate battery charge, bidet, seat warmer, night light, radio/music device, advertising, mini projector, air dryer for the seat and/or the user, AI system, voice command unit, user customization or memory settings, adjustable children seat, automatic seat closing and flushing control, massage device, remote control means, men kick and flush means, dual filtration, touch-free flush means, anti-stick surface, antimicrobial surface, fire retardant materials, UVC disinfection, Wi-Fi connectivity, Bluetooth connectivity or other wireless communication means, odor mitigation unit, unit for adjusting toilet height, and/or safety unit. For instance, medical testing device may conduct one or more medical studies, examples of which include but are not limited to urine tests, dermatology, stool tests, weight measurements, blood pressure tests, and diabetes tests. The safe unit may provide safety protections, such as waterproof and moisture proof, fire protection, leak protection, over current protection, antifreeze protection, and/or short circuit protection. Further, examples of energy source for the toilet seat assembly may include but are not limited to: batter power, kinetic energy, solar energy, mechanical energy, energy created by biodegradation, electric energy, recyclable or green energy, and smart power/energy saving means. 
     Further, as shown in, e.g.,  FIGS.  2  and  3   , the toilet seat assembly according to the present invention may include a triggering mechanism  130  configured for triggering the automatic cleaning, disinfecting, sterilizing, and/or sanitizing procedure by a user, and/or assisting the medical unit to conduct medical studies. Such a triggering mechanism  130  may be electrical and/or mechanical. For instance, the triggering mechanism may include a sensor (e.g., IR sensor). Moreover, a digital display (via wireless or wired communications) may be included to display the status or information, such as status and/or process of the cleaning, disinfecting, sterilizing, and/or sanitizing of the toilet seat, battery life, amount of disinfectant, and/or errors. 
     For instance, when the cover is open and when a “Ready” light is turned on in the digital display, the user may initiate the cleaning, disinfecting, sterilizing, and/or sanitizing cycle or use the seat directly. To initiate the cleaning process, the user may trigger a triggering mechanism (e.g., an IR sensor), upon which the cover automatically closes, and a “Sanitizing” light in the digital display turns on to indicate the ongoing sanitizing or cleaning process. Once the cover is closed, the atomizer(s) spray a mist (e.g., for 7 seconds). After the atomizer(s) turn off, there may be a period of no action (e.g., for 5 seconds), and then optionally dispensing means (e.g., fans) turns on (e.g., for 5 seconds) to disperse the mist along the transport conduit formed by the closed cover and the toilet seat surface. After the cleaning, disinfecting, sterilizing, and/or sanitizing process, the cover is automatically raised, and the “Ready” light is turned on again in the digital display. In some embodiments, a deodorizing substance (e.g., deodorizing oil) may also be sprayed into the toilet bowl some time (e.g., 10 seconds) after the user sits down. 
     Still in some embodiments, the base can be short or long. For instance, the base can be extended (e.g., optionally with an extension) to encompass or over at least part or even the entirety of the toilet bowl. The liquid (e.g., mist) may be injected from the base (or its extension).  FIGS.  10 - 12    illustrate extended/long base  132  with an attached toilet seat  134 .  FIGS.  13 - 14    further illustrate an exemplary toilet seat assembly  200  including extended/long base  132 , toilet seat  134 , and cover  136 . As shown in  FIGS.  10 - 14   , the base  132  (with central hole  138 ) may extend over the entire toilet bowl, e.g., below the toilet seat  134 . As described herein, it is to be understood that different types and shapes of toilet seats and covers (e.g., with or without a transport conduit) can be attached to the base  132  to constitute a toilet seat assembly according to the present invention. 
     In some embodiments, at least one atomizer included by a toilet seat assembly according to the present invention may be an ultrasonic mist atomizer.  FIG.  15    shows the general principal of an exemplary ultrasonic atomizer. As shown in  FIG.  15   , the ultrasonic mist atomizer may include piezo atomizer transducer  1504  (e.g., piezoelectric ceramic plate mounted under a conal case  1506 ), which works by transposing high-frequency sound waves into mechanical energy. As such, the generation of capillary waves is driven by the piezoelectric ceramic plate. Depending on the application, the liquid is transported from liquid injection  1502 , and then to ultrasonic vibrating surface  1508 , which is set into vibration by the oscillating piezo element. As the liquid exits the atomizing surface of the plate, it&#39;s broken into a fine mist of uniform micron-sized droplets, and thus aerosol (mist)  1510  is thereby emitted. For such an exemplary ultrasonic mist atomizer, the frequency may range from about 20 kHz to about 500 kHz. The typical mass median aerodynamic diameter (MMAD) with atomization of water at 100 kHz may be approximately 30 μm; and the typical atomization rate may be up to 0.5 l/h. 
     The present invention also relates to use of an atomizer in a delivery system for disinfecting a surface in general. According to the present invention, the surface (e.g., in a toilet or a sink) remains substantially dry after getting a disinfection by the atomizer. This is significantly different from conventional sprays for disinfecting a surface, which result in wet surface after the disinfection. As such, use of atomizer (e.g., ultrasonic mist atomizer or other types of atomizers) in a delivery system provides advanced features and convenience for cleaning a surface.  FIGS.  16 A-B ,  17 , and  18 A-B further illustrate use of atomizers, e.g., in a toilet seat assembly.  FIGS.  16 A  shows the perspective review of a toilet seat assembly including three atomizers  1602 .  FIG.  16 B  further illustrates an exposed perspective review of atomizers  1602 .  FIG.  17    provides a front review of the toilet seat assembly with atomizers  1602 . Moreover,  FIG.  18 A  provides a side review of the toilet assembly, and  FIG.  18 B  further illustrates an exposed side review showing atomizers  1602 .
