Description

TECHNICAL FIELD

Embodiments are related to the field of polishing devices. Embodiments also relate to devices capable of dispensing polishing compounds. Embodiments further relate to the field of toothbrushes and toothpaste dispensing devices. Embodiments also relate to oral hygiene products that can integrate toothpaste reservoirs within toothbrush handles for improved convenience and hygiene. Furthermore, embodiments pertain to valve-operated dispensing mechanisms that can regulate the flow of polishing compounds.

BACKGROUND

Polishing compounds have been essential in maintaining and restoring the appearance and functionality of various surfaces, including metal, wood, and dental enamel. Traditionally, polishing compounds were applied manually using cloths, brushes, or rudimentary tools, requiring significant effort and skill to achieve consistent results.

In industrial and consumer applications, early polishing devices included simple hand-operated mechanisms, such as buffing wheels and manually squeezed dispensers. These methods often led to inefficiencies, including excessive waste, inconsistent application, and contamination of the polishing compound. Additionally, traditional dispensing methods often required frequent reapplication and manual spreading, which increased labor time and reduced overall effectiveness.

With advancements in technology, more sophisticated polishing systems were developed, including pneumatic and motorized polishing tools. However, these systems frequently lacked precise control over the dispensing and application of the polishing compound, leading to uneven distribution and potential material waste. Furthermore, maintaining hygiene and preventing exposure to contaminants remained a persistent challenge in various industries, particularly in personal care and dental applications.

As the demand for efficient and hygienic polishing solutions increased, the need for an improved method of dispensing polishing compounds became apparent, prompting further innovation in dispensing technologies.

Toothbrushing is an essential part of daily oral hygiene. Traditional toothbrushes require the user to manually apply toothpaste from a separate tube, which can sometimes be inconvenient, especially in situations where portability and ease of use are priorities. To address this, self-dispensing toothbrushes have been developed, integrating a toothpaste reservoir within the toothbrush handle to provide a more efficient and user-friendly brushing experience.

Existing self-dispensing toothbrushes often rely on squeeze mechanisms, pumps, or external cartridges to dispense toothpaste. However, these designs can suffer from several drawbacks, such as inadequate toothpaste control, drying out of the toothpaste, or difficulty in maintaining a watertight seal that prevents contamination. Additionally, many such toothbrushes do not provide a seamless integration of an effective dispensing valve with a long-lasting toothpaste reservoir.

DETAILED DESCRIPTION

The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate one or more embodiments and are not intended to limit the scope thereof.

Subject matter will now be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific example embodiments. Subject matter may, however, be embodied in a variety of different forms and, therefore, covered or claimed subject matter is intended to be construed as not being limited to any example embodiments set forth herein; example embodiments are provided merely to be illustrative. Likewise, a reasonably broad scope for claimed or covered subject matter is intended. Among other things, for example, subject matter may be embodied as methods, devices, components, or systems. Accordingly, embodiments may, for example, take the form of hardware, software, firmware, or any combination thereof (other than software per se). The following detailed description is, therefore, not intended to be interpreted in a limiting sense.

Throughout the specification and claims, terms may have nuanced meanings suggested or implied in context beyond an explicitly stated meaning. Likewise, phrases such as “in one embodiment” or “in an example embodiment” and variations thereof as utilized herein do not necessarily refer to the same embodiment and the phrase “in another embodiment” or “in another example embodiment” and variations thereof as utilized herein may or may not necessarily refer to a different embodiment. It is intended, for example, that claimed subject matter include combinations of example embodiments in whole or in part.

In general, terminology may be understood, at least in part, from usage in context. For example, terms such as “and,” “or,” or “and/or” as used herein may include a variety of meanings that may depend, at least in part, upon the context in which such terms are used. Typically, “or” if used to associate a list, such as A, B, or C, is intended to mean A, B, and C, here used in the inclusive sense, as well as A, B, or C, here used in the exclusive sense. In addition, the term “one or more” as used herein, depending at least in part upon context, may be used to describe any feature, structure, or characteristic in a singular sense or may be used to describe combinations of features, structures, or characteristics in a plural sense. Similarly, terms such as “a,” “an,” or “the”, again, may be understood to convey a singular usage or to convey a plural usage, depending at least in part upon context. In addition, the term “based on” may be understood as not necessarily intended to convey an exclusive set of factors and may, instead, allow for existence of additional factors not necessarily expressly described, again, depending at least in part on context. Furthermore, the term “at least one” as utilized herein can refer to “one or more”. For example, “at least one widget” may refer to “one or more widgets.”

The embodiments disclosed herein seek to overcome the limitations discussed in the background section by introducing a valve-operated polishing apparatus that can ensure controlled, efficient, and sanitary dispensing of a polishing compound directly onto the bristles. As will be discussed in greater detail herein, embodiments can be implemented in the context of a unique 180-degree valve mechanism that allows precise dispensing of a polishing compound while maintaining a watertight seal to prevent contamination. The device can incorporate a threaded shaft base and a pusher plate that can function together to pressurize and direct the flow of the polishing compound through an internal valve stem. This ensures even distribution of polishing compound onto the head of the polishing apparatus while keeping the polishing compound protected from external elements such as moisture and air.

Furthermore, the embodiments can provide additional benefits in terms of usability and hygiene (in the case of, for example, a toothbrush). The reservoir handle can be configured to hold enough polishing compound for approximately 60 uses (but may hold less for short term usage), making it a practical choice for travel or daily use. In one embodiment, the valve-operated polishing apparatus can be designed as a disposable unit, while alternative configurations allow for a reusable system with replaceable polishing apparatus heads and refillable polishing compound cartridges. The polishing apparatus can thus be reusable or disposable, depending up on usage and design considerations. An additional feature of the embodiments can include the optional integration of, for example, dental floss storage within the threaded shaft base, further enhancing the functionality of the device (this floss feature is depicted in more detail in FIG. 6A and FIG. 6B).

By providing an innovative solution to a self-dispensing apparatus, this invention can enhance user convenience, improve oral hygiene efficiency (e.g., in the case of a toothbrush), and reduce waste associated with, for example, traditional toothpaste tubes and other types of storage containers for polishing compounds. The disclosed novel valve mechanism and integrated reservoir system make it a superior alternative to existing products in the market.

Note that the term “polishing compound” as utilized herein, can relate to a substance containing fine abrasives or chemical agents used to smooth, refine, clean or enhance the surface finish of materials by removing imperfections, oxidation, or surface irregularities. Polishing compounds can come in various forms, including pastes, creams, liquids, and solid bars, and are commonly used in applications such as metalworking, woodworking, dentistry, automotive detailing, and jewelry maintenance. The composition of a polishing compound may include abrasives (such as silica, aluminum oxide, or diamond particles), binders, and lubricants to facilitate application and achieve a desired level of surface refinement. The term polishing compound as used herein can include substances such as toothpaste, which functions as a mild abrasive for cleaning and polishing teeth, in addition to compounds used for polishing metals, wood, jewelry, and other surfaces.

FIG. 1 illustrates a schematic diagram depicting a front view of a valve-operated polishing apparatus 100, in accordance with an embodiment. It can be appreciated that in some embodiments, the valve-operation polishing apparatus 100 may function as a valve-operated dispensing toothbrush. In other embodiments, the valve-operated polishing apparatus 100 can function as other types of devices, such as a jewelry polisher, a nail polisher, optical lens polisher, dental polisher, wood polisher, a shoe polisher, a leather polisher and so on. The valve-operated polishing apparatus 100 also includes a reservoir handle, a pressurizing mechanism, and a valve-controlled dispensing system that allows for precise application of a polishing compound. The reservoir handle stores toothpaste or other types of polishing compounds, and the valve assembly ensures controlled and hygienic dispensing onto the bristles.

The valve-operated polishing apparatus 100 can be implemented in some embodiments as other types of polishing devices, depending on the type of polishing compound stored within the reservoir and the configuration of the head. For example, when adapted as a jewelry polisher, the apparatus may dispense a fine polishing paste or liquid onto a buffing pad or brush for cleaning and restoring the luster of metal or gemstone surfaces. As a nail polisher, the device may apply a buffing compound to enhance the smoothness and shine of fingernails or toenails. In the context of an optical lens polisher, the apparatus may deliver a micro-abrasive solution for refining and cleaning eyeglass or camera lenses without causing scratches. Similarly, in a dental polisher application, the device may be used to apply polishing pastes to teeth for stain removal and enamel smoothing. Additionally, when implemented as a wood polisher, the apparatus may dispense a finishing compound onto a polishing pad or brush for treating and enhancing wooden surfaces.

These varied embodiments demonstrate the versatility of the valve-operated polishing apparatus 100, making it applicable across multiple industries and personal care applications. The ability to deliver a controlled amount of polishing compound directly to the desired surface minimizes waste, enhances efficiency, and improves the overall user experience.

FIG. 2 illustrates a schematic diagram depicting a back or front cut-away view of the valve-operated polishing apparatus 100, in accordance with an embodiment. FIG. 3 illustrates a schematic diagram depicting a cut-away side view of the valve-operated polishing apparatus 100, in accordance with an embodiment.

The valve-operated polishing apparatus 100 shown in FIGS. 1-5 and in the other figures can include a number of components including but not limited to, for example, the reservoir handle 104 and the valve stem housing 106. Note that the aforementioned valve stem housing can also be referred to as a head valve housing or simply “the head”.

The reservoir handle 104 is located on the lower or bottom portion of the valve-operated polishing apparatus 100 and the valve stem housing 106 is located in the upper portion of the valve-operated polishing apparatus 100. Valve stem housing 106 contains the polishing head face 108 that maintains and supports a group of bristle anchor holes (sometimes called bristle tuft holes) 101. The bristle anchor holes 101 can be configured to secure bristles in place in some embodiments and form part of the bristle pad.

The reservoir handle 104 can engage with and/or can be connected to a base 102, which can contain an indentation 103, which a user can manipulate to assist in turning the base 102. The indentation 103 is shown in FIG. 1 at the bottom of the valve-operated polishing apparatus 100 on the base 102. Note that in some embodiments, an optional electronic button can be incorporated into the base 102 at the location of the indentation 103 or another position on the base 102, which can activate a battery-operated motor for powered brushing.

The valve-operated polishing apparatus 100 includes a reservoir 114 in the reservoir handle 104 that can manually (i.e. initiated with a user input) dispense a sufficient amount of polishing compound stored in the reservoir 114 onto the head face 108 by turning the base 102 180 degrees which in turn turns the internal valve stem 110. The bottom of the threaded shaft base 102 can be configured to be twisted to push a pusher plate 127 up the threaded shaft 112 and pressurize the polishing compound residing in the reservoir 114 of the reservoir handle 104. Note that in some embodiments, the reservoir handle 104 may be optionally configured with a transparent material that allows a user to view contents. The polishing compound can sit within the reservoir 114 of the reservoir handle 104.

When the polishing compound is pressurized through this sequence of operation, the polishing compound will take the path of least resistance into the horizontal cavity 137 at the top of the threaded shaft base 112 and divert vertically up the internal valve stem 110. The top of the internal valve stem 110 has two openings 135 perpendicular to the tubular shaft of the internal valve stem 110. The internal valve stem 110 fits into the valve stem opening 117 of the valve stem housing 106 (i.e., can also be referred to simply as the “head” or the “head valve housing”). The perpendicular openings on the internal valve stem 110 and the perpendicular opening 121 at the center of head face 108 line up horizontally.

When the polishing compound reaches the top of the valve stem while the shaft is being turned, the polishing compound is then forced through the open perpendicular opening 135 on the valve stem that lines up with the perpendicular opening 121 on the polishing apparatus head and polishing compound is then dispensed onto the head face 108 and bristles. When the valve is turned 90 degrees, the valve is fully open. When the valve completes the 180 degree turn, the valve is fully closed and sealed water tight with either tolerance or by a silicon type gasketed valve tip to keep contaminants (e.g., water, saliva, etc.) out of the polishing compound and also keep it from drying out.

The thread pattern on the threaded shaft base 112 and the volume of the reservoir handle 104 can be configured to allow, for example, 60 uses (e.g., in the case of brushing of teeth) and should last, for example, 30 days (e.g., brushing teeth twice a day). The valve-operated polishing apparatus 100 can be configured to be a 30-day disposable toothbrush for sanitary benefits of replacing a used toothbrush.

Variants of this approach can be more permanent in some alternative embodiments by replacing the head and inserting a polishing compound cartridge into a more permanent body and a battery operated polishing apparatus head. The reservoir handle 104 can be of a solid color or may be implemented as a clear body apparatus to allow the user to view the amount of polishing compound left in the valve-operated polishing apparatus 100. An alternative embodiment of the threaded shaft base 112 can also house a small spool of dental floss with a cutter to dispense dental floss as shown, for example, in FIG. 6A, FIG. 6B, and FIG. 6C. A varied amount of polishing compound in the reservoir can allow for shorter term use applications.

The reservoir handle 104 houses the polishing compound and can be configured to include the threaded shaft base 112 along with the pusher plate 127. The reservoir handle 104 can hold a sufficient amount of polishing compound to last, for example, 60 brushes or, for example, 30 days assuming brushing twice a day. The reservoir handle 104 an include a hole 134 at the general base 159 with side cutout(s) 136 for “clicking” or a “click” that engages the wedge 161 on the base 102 of the threaded shaft 112 thereby keeping the threaded shaft 112 in firm position when not being turned. Note that the general base 159 is shown in FIG. 5 as indicated by a dashed oval. The general base 159 is essentially an area that includes, for example, hole 134 and cut-out(s) 136.

The threaded shaft base 112 includes a side or horizontal cavity 137 on the tubular top section 115 of the threaded shaft base 112. The external shaft of the tubular top section 115 can be shaped to fit into the thicker portion 116 of the valve stem 110. The bottom of the threaded shaft base 112 can be spring clipped via a spring clip 132 into the hole 134 on the reservoir handle 104.

The pusher plate 127 is the plate that pushes polishing compound out of the reservoir handle 104 into the horizontal cavity 137 and into the valve stem 110. The pusher plate 127 has a tolerance to the inside diameter of the reservoir handle 104. The pusher plate 127 also has a female threaded portion 139 that matches the shaft thread of the threaded shaft base 112.

The internal valve stem 110 is a tubular stem that can connect to the threaded shaft base 112 and can guide the polishing compound to the head face 108. The internal valve stem 110 has two perpendicular holes or openings 135 that line up with the hole 121 in the head 108 when assembled. The top of the valve tube (i.e., one of the perpendicular holes 135) is closed so polishing compound is forced through the perpendicular hole 135 that is open when turned. When the threaded shaft base 112 in a 90 degree position, the internal valve stem 110 fully opened and then fully closed with a 180 degree turn.

The internal valve stem 110 can be configured with a liquid sealed tolerance to the female valve opening/hole 117 (e.g., with an O-ring). It should be appreciated that the head face 108 is part of the valve stem housing 106. The valve stem housing 106 in turn can surround and maintain the internal valve stem 110 (which also can be referred to as the valve 110) within the female valve opening/hole 117. The internal valve stem 110 and the female valve opening/hole 117 can together form a valve assembly. The valve assembly includes the perpendicular openings as discussed previously. A dispensing pathway from the reservoir 114 to the head (e.g., the head face 108) can be created through the implementation of such a valve assembly. This valve assembly along with the volume of the reservoir handle 104 and the thread count can be configured to dispense a controlled amount of the polishing compound per cycle by user actuation.

The valve stem housing 106 includes the polishing apparatus head face 108 and the internal valve stem 110. A perpendicular hole 121 can be located in the center of the bristle pad to allow the polishing compound to be dispensed onto the head face 108 and into the bristles. The bristle pad can include the group of bristle anchor holes (sometimes called bristle tuft holes) 101 discussed earlier. In some embodiments, the valve stem housing 106 can be separate from the reservoir handle 104 for 3D printing purposes. In the case of injection molding, however, the valve stem housing 106 and the reservoir handle 104 may be one piece. Similarly, in some situations the internal valve stem 110 and the threaded shaft base 112 may be configured as a single piece or may be configured in separate pieces and then engaged with one another.

FIG. 4 illustrates a schematic diagram depicting components of the valve-operated polishing apparatus 100, in accordance with an embodiment. The valve-operating polishing apparatus 100 can include the internal valve stem 110 which can be maintained within the valve stem housing 106. FIG. 4 depicts the threaded shaft base 112 with the tubular top section 115 configured at the top of the threaded shaft base 112. The spring clip(s) 132 is depicted as located toward the bottom of the threaded shaft base 112. The indentation 103 is also shown in FIG. 4 with respect to the base 102. The tubular top section 115 includes a hole or horizontal cavity 137. Note that the hollow portion 109 of the internal valve stem 110 is shown in FIG. 5.

FIG. 4 also shows the valve stem housing 106 as having an O-ring portion 123, which can engage with a portion 125 of the reservoir handle 104. That is, the valve stem housing 106 can connect with the reservoir handle 104 through the engagement of the O-ring portion 123 into the portion 125 of the reservoir handle 104. The pusher plate 127 is also shown in FIG. 4. It can be appreciated that the use of such O-rings is optional and that other types of engagement or connecting mechanisms or adhesives may be implemented in different embodiments, depending upon design considerations. In other words, the embodiments are not limited to the use of just O-rings.

FIG. 5 illustrates a schematic diagram depicting a cut-away view of components of the valve-operated polishing apparatus 100, in accordance with an embodiment. The configuration shown in FIG. 5 illustrates various components and view of the valve-operated polishing apparatus 100 including, for example, the pusher plate 127 with the female threaded portion 139. Note that in some embodiments, the pusher plate 127 can be surrounded by an O-ring seal.

The threaded shaft base 112 is also illustrated in FIG. 5 with the spring clip(s) 132 located toward the bottom of the threaded shaft base 112. A wedge 161 is also depicted in FIG. 5 on the base 102. The tubular top section 115 is also shown in FIG. 5 located at the top of the threaded shaft base 112. Furthermore, the horizontal cavity 137 is shown with respect to the tubular top section 115. It can be appreciated that the pusher plate 127 threads onto the threaded shaft base 112.

The internal valve stem 110 (also referred to in some cases as simply the “valve stem”) is also shown FIG. 5 with the two perpendicular holes or openings 135. Note that in some embodiments, the internal valve stem 110 may be topped with a sealed tip. As discussed previously, the internal valve stem 110 includes a hexagonal shaped portion 116, which in turn engages with the hexagonal tubular top section 115 of the threaded shaft base 112.

Note that a sequence of operation of the valve-operating polishing apparatus can involve a series of operational steps including but not limited to, for example, a user turning the base 102 180 degrees, which in turn turns the threaded shaft base 112 and the internal valve stem 110, and pushes the pusher plate 127, which pressurizes the polishing compound in the reservoir 114 and forces the polishing compound up the internal valve stem 110 an through whichever opening(s) 135 is lined up with the hole 121 on the head face 108.

When the polishing compound is pressurized through this sequence of operation, it follows the path of least resistance into the horizontal cavity 137 at the top of the threaded shaft base 112 and then diverts vertically up the internal valve stem 110. This structured flow path ensures that the compound is delivered efficiently without clogging or excessive buildup. The top of the internal valve stem 110 includes two openings 135 that are positioned perpendicular to the tubular shaft of the internal valve stem 110, allowing the polishing compound to be directed outward when twisted and aligned.

The internal valve stem 110 can be securely fitted into the valve stem opening 117 of the valve stem housing 106 of the polishing apparatus 100, which can ensure a stable and sealed connection. When one of the perpendicular openings 135 on the internal valve stem 110 aligns with the perpendicular opening 121 at the top of the valve stem housing 106, the polishing compound is dispensed onto the head face 108 for application.

This design can provide a reliable and efficient mechanism for dispensing polishing compounds with precision. The integration of a pressurizing mechanism and a controlled valve system enhances usability, preventing waste while ensuring even distribution of the polishing compound. Additionally, the ability to manually control dispensing through a simple rotation mechanism renders the apparatus intuitive and convenient for users in a variety of applications.

FIG. 6A, FIG. 6B, and FIG. 6C illustrate a schematic diagram depicting components of the threaded shaft base 112, in accordance with an embodiment. The threaded shaft base 112 is shown in FIG. 6A with a floss dispenser, while only a cut-away view of the lower portion of the threaded shaft base 112 is depicted in FIG. 6B. FIG. 6C specifically shows a floss base cap 141. The previously mentioned floss feature is depicted in FIG. 6A and FIG. 6B. A floss spool 133 is shown in FIG. 6A and can be stored within the base 102 shown in FIG. 6A. The base 102 shown in FIG. 6A and FIG. 6B is an alternative base. That is, it is slightly larger than the previously illustrated base 102 in the other figures. Floss can be dispensed from the floss spool 133, which can be stored in a cavity within the alternative base 102 shown in FIG. 6A and FIG. 6B. The base 102 can be configured with a compartment that houses the spool 133 of dental floss along with a cutter (not shown in the figure) for dispensing dental floss. The spool 133 can be located on a spool stem/shaft 142.

FIG. 7 illustrates a flow chart depicting logical operational steps of a method 200 for dispensing a polishing compound using the valve-operated polishing apparatus 100, in accordance with an embodiment. As depicted at block 202, a step or operation can be implemented for pressurizing a polishing compound within the reservoir handle 104 by rotating the threaded shaft base 112, thereby moving the pusher plate 127 along the threaded shaft base 112. Next, as depicted at block 204, a step or operation can be implemented for directing the pressurized polishing compound through a dispensing pathway in the valve-operated poshing apparatus 100. Then, as illustrated at block 206, a step or operation can be implemented for controlling the flow of the polishing compound using a valve assembly that includes the internal valve stem 110 having perpendicular openings 135. Thereafter, as indicated at block 208, a step or operation can be implemented for dispensing the polishing compound from the reservoir to the head face 108 through the valve stem housing 106.

Note that additional steps or operations may involve, for example, configuring the pusher plate to move linearly along the threaded shaft base to maintain consistent pressurization of the polishing compound, and/or configuring the internal valve stem to rotate up to 180 degrees between a first position and a second position.

It can be appreciated that the steps, operations, or techniques described herein can be applied to various types of valve-operated polishing apparatuses, methods or systems. In the above description, specific details of various embodiments are provided. However, some embodiments may be practiced with less than all of these specific details. In other instances, certain methods, procedures, components, structures, and/or functions are described in no more detail than to enable the various embodiments of the invention, for the sake of brevity and clarity.

Although the operations of the method(s) herein are shown and described in a particular order, the order of the operations of each method 200 may be altered so that certain operations may be performed in an inverse order or so that certain operations may be performed, at least in part, concurrently with other operations. In another embodiment, instructions or sub-operations of distinct operations may be implemented in an intermittent and/or alternating manner.

It should also be noted that at least some of the operations for the method 200 described herein may be implemented using software instructions stored on a computer useable storage medium for execution by a computer. As an example, an embodiment of a computer program product may include a computer useable storage medium to store a computer readable program.

The computer-useable or computer-readable storage medium can be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system (or apparatus or device). Examples of non-transitory computer-useable and computer-readable storage media include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk, and an optical disk. In the context of consumer devices, the aforementioned non-transitory computer-useable and computer-readable storage media can include microchips embedded in smart appliances (e.g., such as an electronically operated valve-operated polishing), which utilize specialized integrated circuits (ICs) and microcontrollers with onboard memory to facilitate intelligent operation, real-time data processing, and connectivity features.

Alternatively, embodiments may be implemented entirely in hardware or in an implementation containing both hardware and software elements. In embodiments which use software, the software may include but is not limited to firmware, resident software, microcode, etc.

In view of the foregoing, the embodiments provide a reliable, efficient, and user-friendly apparatus for dispensing a polishing compound with improved control, precision, and hygiene.
