Description

Technical Field

[0001] The utility model relates to the technical field of sanitary equipment, and more particularly to a low-water-consumption toilet. Background Art

[0002] At present, in some parts of my country, due to the lack of water resources or limited conditions, there are no ready-made sewers and old-style toilets are still used. Old-style toilets are unhygienic and easily breed mosquitoes and spread germs. Some existing technologies have proposed more hygienic portable toilets. This type of toilet is connected to a sewage storage tank for holding sewage. When the sewage storage tank is full, the user needs to empty the sewage storage tank for next use.

[0003] For example, a Chinese patent document (publication number: CN 220058227 U) provides an anti-clogging structure for a low-water-consumption toilet, including a toilet bowl that forms an isolation water seal, so that when the sewage pump is working, a pressure difference is formed at both ends of the sewage inlet pipe to allow sewage to enter and discharge the sewage pump, and a sewage inlet pipe connected between the toilet bowl and the sewage pump, with a pressure difference bend in the sewage inlet pipe, in which a sewage pump can be formed; the sewage pump is provided with a sewage crushing part and a sewage discharge part to crush and then discharge the sewage.

[0060] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0061] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, for the purposes of describing the embodiments of the present application herein.

[0062] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "transverse", "longitudinal" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to having a specific orientation, or to be constructed and operated in a specific orientation. Moreover, in addition to being used to indicate orientations or positional relationships, some of the above terms may also be used to indicate other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in certain circumstances. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0063] As the first implementation mode of this embodiment, Figure 1 As shown, this embodiment provides a low water consumption toilet, including a toilet bowl 100 and a sewage pump 200.

[0064] Specifically, the low-water-consumption toilet further includes a support shell 300 and a water tank 400. The support shell 300 is used to accommodate the toilet bowl 100, and the water tank 400 is arranged on the support shell 300. More specifically, the water tank 400 and the sewage pump 200 are located on the same side of the toilet bowl 100 to improve the space utilization of the low-water-consumption toilet and make it more portable.

[0065] Specifically, the low-water-consumption toilet further includes a sewage pipe 500 , the pump outlet 240 is in communication with the sewage pipe 500 , and the sewage pipe 500 passes through the side wall of the support shell 300 . Optionally, the sewage pipe 500 is a hose and / or a hard pipe.

[0066] Among them, Figure 1 As shown, the bottom of the toilet 100 has a roughly horizontal sewage outlet 110. The "roughly horizontal" here specifically means that the sewage outlet 110 is oriented horizontally, or can be slightly tilted, and cannot be oriented directly upward or downward. When it is oriented directly upward, the sewage pump 200 is not convenient for sucking materials, or when it is oriented directly downward, the sewage is likely to fall into the sewage pump 200 due to direct gravity.

[0067] Among them, Figure 2 、 3As shown, the sewage pump 200 includes a motor 210 and a working chamber 220. Specifically, a pump inlet 230 and a pump outlet 240 are provided on both sides of the working chamber 220 of the sewage pump 200. Waste or liquid enters through the pump inlet 230 and is pumped out through the pump outlet 240. The pump inlet 230 is connected to the toilet 100 via a connector 600. The connector 600 has a connecting channel 610. The inlet end 620 of the connecting channel 610 is connected to the sewage outlet 110, and the outlet end 630 of the connecting channel 610 is connected to the pump inlet 230. In addition, the pump inlet 230 is not lower than the bottom of the sewage outlet 110 in the horizontal direction. Specifically, the top of the pump inlet 230 is not lower than the bottom of the sewage outlet 110 in the horizontal direction. That is, based on the horizontal direction, the pump inlet 230 is at least partially higher than the bottom of the sewage outlet 110. In this way, the pump inlet 230 of the sewage pump 200 cooperates with the roughly horizontal sewage outlet 110, so that when the sewage pump 200 is not working, its water storage capacity is further improved, avoiding excessive water leakage directly from the sewage pump 200, reducing the water consumption of the toilet, and reducing the burden on users to clean the sewage storage tank.

[0068] It is worth noting that the connector 600 can be integrated with the sewage pump 200 or can be separated from the sewage pump 200. When the connector 600 is integrated with the sewage pump 200, its outlet end 630 coincides with the pump inlet 230.

[0069] Among them, Figure 4 As shown, the axis of the connecting channel 610 is a curve or a straight line to match the layout of the sewage pump 200. Specifically, the connecting member 600 can be a straight pipe or a curved pipe or a ring structure. In order to achieve high efficiency and water saving, the connecting member 600 should be as short as possible, while reducing the degree of bending to reduce the resistance to the passage of sewage.

[0070] Optionally, the connector body may be a split structure, with the two split structures being sealed and connected to each other.

[0071] Preferably, Figure 4 As shown, at least a portion of the inlet end 620 and the outlet end 630 of the connector 600 are linearly connected, preventing the connector 600 from being bent excessively and hindering the passage of waste. "Linear connection" specifically means that a straight line passes from the inlet end 620 to the outlet end 630 without any physical obstruction or interference. This line does not necessarily need to be horizontal or vertical; it can also be an oblique line.

[0072] More specifically, the length of the connecting member 600 in the horizontal direction is 10-50 mm, for example, 14 mm, 20 mm, 25 mm or 30 mm.

[0073] Preferably, Figure 4As shown, the angle between the perpendicular line of the inlet end 620 of the connecting channel 610 and the perpendicular line of the outlet end 630 is greater than 100°, such as 115°, 120°, 135° or 160°. Within this range, the water-saving capacity of the toilet is further improved. At the same time, since the outlet end 630 needs to be adapted to the pump inlet 230, the direction of the perpendicular line of the outlet end 630 is consistent with the direction of the perpendicular line of the pump inlet 230. At this time, if the perpendicular line of the inlet end 620 and the perpendicular line of the outlet end 630 deviate more from each other, the inlet end 620 will deviate more from the suction direction of the sewage pump 200, which is not conducive to the operation of the sewage pump 200, and requires higher suction force of the sewage pump 200, resulting in higher cost.

[0074] It is worth noting that the angles in this embodiment are all angles between lines, between planes, or between a line and a plane.

[0075] As a second embodiment of this embodiment, based on the first embodiment, the specific structure of the low water consumption toilet is as follows:

[0076] The connecting member 600 is connected to the toilet bowl at one side close to the inlet end 620 through a fastener, which may be a bolt, or a clamp, a buckle or other component.

[0077] As a further solution, the aforementioned fastener may also be provided on a side of the connecting member 600 close to the outlet end 620 .

[0078] In the related art, if the sewage outlet is set downward, the sewage outlet can be directly inserted into the sewage pump through the sealing ring without the need to set up additional connecting parts. In the process of transporting sewage and other water liquids from the sewage outlet to the sewage pump, the sewage and other water liquids fall by gravity, and there is basically no risk of overflow.

[0079] Since the low-water-consumption toilet of this embodiment cannot discharge waste into the sewer pipe, in order to meet various needs, the sewage outlet 110 is roughly arranged horizontally, and the connecting piece 600 and the fasteners thereon are used to firmly connect the toilet 100 to the sewage pump 200, reducing the risk of leakage of waste or water.

[0080] Specifically, if Figure 5As shown, a connecting plate 650 is formed on one side of the connector 600 near the inlet end 620. The connecting plate 650 extends radially from the inlet end 620. The connecting plate 650 is connected to and fits snugly with the bowl 100, increasing the contact area between the connector 600 and the bowl 100. The connector 600 is mounted on the connecting plate 650. Since the pump body may cause resonance in the connector 600 during operation, a weak connection between the connector 600 and the bowl 100 could potentially cause the connection to become disconnected, causing the toilet to malfunction. The provision of the connecting plate 650 further stabilizes the connection between the connector 600 and the bowl 100 and further distributes vibrational forces exerted on the connector 600 to the bowl 100, reducing mechanical damage to the connection point between the connector 600 and the bowl 100.

[0081] Further, such as Figure 6 As shown, a reinforcing rib 660 is provided on the side of the connecting plate 650 away from the inlet end 620. The reinforcing rib 660 connects the connecting plate 650 and the outer side wall of the connecting member 600 to prevent the connecting plate 650 from breaking when subjected to external force.

[0082] Further, such as Figure 5 、 6 As shown, a first positioning portion 651 is provided on the outer edge of the connecting plate 650, and a second positioning portion 120 is provided on the side of the toilet 100 close to the sewage outlet 110; the first positioning portion 651 is plugged into the second positioning portion 120 to limit the circumferential movement of the connecting plate 650, so that the connecting member 600 is accurately matched with the toilet 100.

[0083] Furthermore, the first positioning portion 651 is constructed as a notch 651a, and the second positioning portion 120 is constructed as an insert plate 121, and the insert plate 121 is formed with a slot 121a for cooperating with the notch 651a, and the depth direction of the slot 121a is consistent with the radial direction of the connecting plate 650, wherein a portion of the insert plate 121 is at least partially located in the notch 651a, so that the connecting plate 650 is supported by the insert plate 121 when it moves laterally or circumferentially.

[0084] Further, such as Figure 5 As shown, the connecting plate 650 includes at least a plurality of connecting support plates 652 , each of which is provided with a fastener. The number of the connecting support plates 652 may be 2, 3, or 4.

[0085] Furthermore, Figure 5As shown, each connecting support plate 652 has a circular hole formed therein for receiving a threaded fastener assembly 640. The threaded fastener may be composed of a bolt and a nut. The threaded fastener assembly 640 serves as a fastener to allow a user to quickly disconnect the sewage pump 200 from the urinal 100, making it easier for the user to clean, repair, replace, or maintain the urinal 100 or sewage pump 200.

[0086] Furthermore, Figure 5 As shown, the connecting plate 650 includes three connecting support plates 652, each of which is provided with a fastener. The three connecting support plates 652 and the first positioning portion 651 are arranged at 90° intervals along the circumference of the inlet end 620. The combination of the connecting support plates 652 and the first positioning portion 651 restricts the movement of the connecting member 600, thereby enhancing the connection stability of the connecting member 600, with a compact layout and a reasonable structure.

[0087] Among them, the connecting piece 600 has a mounting groove on one side close to the inlet end 620 and / or the outlet end, and a sealing ring is clamped in the mounting groove, which further enables the connecting piece 600 to be sealedly connected to the toilet 100 or the sewage pump 200.

[0088] Preferably, when the connector 600 of this embodiment is connected to the toilet 100 or the sewage pump 200, a multi-stage sealing structure is formed near the connection. On the basis of the fastener and the sealing ring, other structures are used to prevent dirt or water from leaking out as much as possible.

[0089] Specifically, such as Figure 5 As shown, a first mounting groove 670 is provided on one side of the connecting member 600 close to the inlet end 620. The bottom surface of the first mounting groove 670 is parallel to the inlet end 620 and surrounds the inlet end 620. A sealing ring is clamped in the first mounting groove 670. The thickness of the sealing ring is greater than the depth of the first mounting groove 670, and the diameter of the sealing ring 670 is greater than the diameter of the inlet end 620.

[0090] More specifically, Figure 5 As shown, the wall of the first mounting groove 670 at least partially protrudes from the connecting plate 650, so that a ridge structure is formed on the side of the connecting plate 650 facing the toilet 100. Figure 7 As shown, the toilet 100 is provided with an annular groove 130 on the outer periphery of the sewage outlet 110. The groove 130 is recessed relative to the sewage outlet 110 and is used to come into contact with the side wall of the first mounting groove 670, so as to facilitate the user to quickly install the connecting piece 600 to the accurate position of the toilet 100 and prevent the connecting piece 600 from slipping during the installation process. The annular mounting groove 130 also plays a certain sealing role.

[0091] Specifically, one side of the connecting member 600 close to the outlet end 630 axially extends from the pump inlet 230 to the interior of the sewage pump, and abuts against a portion of the inner wall of the sewage pump 200 .

[0092] Specifically, the connector 600 is circumferentially provided with a second mounting groove 680 on one side of the outlet end 630 . A sealing ring is clamped in the second mounting groove 680 , and the bottom surface of the second mounting groove 680 is parallel to the outlet end 630 .

[0093] More specifically, combined Figure 8 、 Figure 9 The side wall of the second mounting groove 680 near the outlet end 630 extends axially from the pump inlet 230 to the interior of the sewage pump 200. Part of the inner wall of the sewage pump 200 protrudes inward to form an internal card platform. The connecting part abuts against the internal card platform and forms a three-level sealing structure with the fastener, further reducing the risk of liquid leakage and pressure leakage. Among them, the side wall of the second mounting groove 680 near the outlet end 630 is higher than the side wall of the second mounting groove 680 away from the outlet end 630.

[0094] Furthermore, the inner card platform is arranged on the inner wall of the sewage pump 200, and the inner diameter of the inner card platform is equal to the diameter of the outlet end 630. In addition, the inner card platform is located on the end face of the working chamber, so that the connecting piece 600 passes directly through the working chamber, reducing the resistance of liquid passage.

[0095] As a third embodiment of this embodiment, based on the first or second embodiment or a combination thereof, the specific structure of the low water consumption toilet is as follows:

[0096] Preferably, Figure 10 As shown, there is at least one flow block between the toilet 100 and the sewage pump 200. The flow block is a portion of the lower side of the connector 600 and / or the sewage pump 200 and protrudes upward. The provision of this flow block can minimize the possibility of waste and air entering the sewage pump 200 and then flowing back into the toilet 100.

[0097] Preferably, Figure 10 As shown, the connecting passage 610 is at least partially smaller than the working chamber 220, further reducing the water loss caused by the installation of the connector 600. Furthermore, because the connecting passage 610 is further contracted relative to the working chambers 220 of both the sewage pump 200 and the urinal 100, it is more difficult for sewage to flow directly into the sewage pump 200 when the pump is not operating, thus providing a certain degree of blockage prevention. Furthermore, the urinal 100, the connecting passage 600, and the working chamber 220 of the sewage pump 200 form a structure similar to a Venturi tube. Waste flows from the larger passage into the smaller passage, and then into the expanded passage. The waste is pressurized before entering the sewage pump 200, further enhancing the sewage discharge capacity of the low-water-consumption toilet.

[0098] Optionally, the middle portion of the connecting member 600 contracts so that the dirt is released after passing through the middle portion of the pressing member.

[0099] Optional, such as Figure 11 As shown, the inlet end 620 of the connector 600 is larger than the outlet end 630. The inlet end 620 is adapted to the sewage outlet 110, and the outlet end 630 is adapted to the pump inlet 230. The axial cross-section of the inner wall of the connector 600 is streamlined to prevent the inner wall of the connector 600 from causing contaminants to be stuck.

[0100] Specifically, the connecting channel 610 may be tapered.

[0101] As a fourth embodiment of this embodiment, based on the first, second, or third embodiments or a combination thereof, the specific structure of the low water consumption toilet is as follows:

[0102] The toilets involved in this application generally need to discharge waste from the sewage pipe 500 into a sewage storage tank rather than into the sewer. Since the sewage storage tank is at a certain height, the sewage pipe 500 needs to be relatively elevated. In some cases, especially when the sewage storage tank is placed outdoors, the sewage pipe 500 needs to be connected to the sewage storage tank outside through a window. During this process, the toilet may face insufficient pumping power.

[0103] Preferably, Figure 12 As shown, the pump outlet 240 is facing upward or diagonally upward, so that the waste is pumped upward. Generally speaking, the sewage pump 200 is located near the toilet 100 and is at a lower position. If the pump outlet 240 is facing horizontally or downward or diagonally downward, the waste will be further discharged to a lower position, and the waste will not be effectively transported to the waste storage tank (used to receive waste discharged from the toilet). Specifically, if the pump outlet 240 of the sewage pump 200 is facing upward, the pumping force of the sewage pump 200 can lift the waste, which is suitable for transporting waste to a higher position. However, if the outlet of the sewage pump 200 is facing downward or horizontally, in order to match the waste storage tank, the waste will also need to overcome gravity to flow upward, which may cause the waste to get stuck in the pipe on the way to the waste storage tank.

[0104] At the same time, by adopting the above structure, the sewage pump 200 can further prevent the water from flowing out due to gravity when not working, so that the water storage capacity is further enhanced.

[0105] Furthermore, a mounting hole is opened on the side wall of the support shell 300, and the sewage pipe 500 passes through the mounting hole. The mounting hole is higher than the pump outlet 240, so that the discharge direction of the sewage is further lifted upward to adapt to the operation of the sewage pump 200.

[0106] Therefore, the sewage outlet 110, the pump outlet 240 and the connecting channel 610 of this embodiment cooperate with each other. From the structural layout level, they are in line with the working conditions of low-water-consumption toilets, reduce the load requirements and workload of the portable toilet on the sewage pump 200 body, and enable the sewage to be efficiently pumped out to the sewage storage tank.

[0107] As the fifth embodiment of this embodiment, based on the first, second, third, or fourth embodiments or a combination thereof, the specific structure of the low water consumption toilet is as follows:

[0108] Specifically, such as Figure 13 As shown, the working chamber 220 of the sewage pump 200 includes a sewage chamber 221. An impeller is disposed in the sewage chamber 221. The circumference of the impeller faces the pump outlet 240. More specifically, the planes where the pump inlet 230 and the pump outlet 240 are located are perpendicular to each other.

[0109] More specifically, Figure 13 As shown, the working chamber 220 of the sewage pump 200 also includes a crushing chamber 222. The pump inlet 230 is located on one side of the crushing chamber 222. A crushing wheel, consisting of several blades, is installed within the crushing chamber 222. This wheel rotates to crush waste, preventing it from clogging the toilet bowl and reducing the pressure of waste discharge, thereby reducing water consumption. The crushing wheel and impeller are synchronously driven by the rotating shaft of the motor 210. The pump inlet 230, crushing chamber 222, and sewage chamber 221 are arranged in sequence along the axis of the rotating shaft.

[0110] It is worth noting that the working chamber 220 of the sewage pump 200 involved in this application only includes the sewage chamber 221 and / or the crushing chamber 222. In some cases, the pump inlet 230 of the sewage pump 200 may extend relative to the crushing chamber 222 to cooperate with the outlet end 630 of the pressurizing member. However, the interior space of this extended portion does not serve as the working chamber 220 of the sewage pump 200.

[0111] Further, such as Figure 14 As shown, the pump inlet 230 is eccentrically arranged relative to the crushing chamber 222. That is, the centerline of the pump inlet 230 is offset from the centerline of the crushing chamber 222. It can be eccentric upward or downward. This can also prevent the dirt from directly entering the crushing wheel and causing the crushing wheel to jam.

[0112] Furthermore, the lower side of the outlet end 630 is flush with or higher than the lower side of the crushing chamber 222, that is, the lower side of the outlet end 630 does not protrude from the lower side of the crushing chamber 222. If the lower side of the outlet end 630 is lower than the side wall of the crushing chamber 222, this may cause the part of the pump inlet 230 below the crushing chamber 222 to accumulate dirt, resulting in a suction dead angle for the sewage pump 200, making it difficult for the sewage pump 200 to extract the dirt, and making it more difficult to clean the toilet.

[0113] Furthermore, the portion of the connecting member 600 near the outlet end 630 is contracted, that is, the outlet end 630 is smaller than the inlet end 620. Since the inlet end 620 is adapted to the pump inlet 230, the radial cross-sectional area of ​​the pump inlet 230 is simultaneously smaller than the radial cross-sectional area of ​​the crushing chamber 222. The outlet end 630 is located within the radial projection range of the crushing chamber 222, reducing the crushing content of the crushing wheel per unit time, so that the crushing wheel can fully crush the dirt.

[0114] Preferably, Figure 15 As shown, the rotation axis of the motor 210 is arranged horizontally or at an angle, that is, the rotation axis of the motor 210 is parallel to the horizontal line or at an angle less than 90°. This forms a barrier between at least a portion of the crushing chamber 222 and / or the sewage chamber 221 and the urinal 100, which is used to contain liquid and form a water seal. It is worth emphasizing that the barrier in this application can include one or more entities.

[0115] As an optional solution, the motor 210 is tilted upward so that the upper portion of the crushing chamber 222 is higher than the sewage outlet 110, forming a barrier between the two. Water can be contained in this area to form a water seal, thereby blocking air from flowing. Specifically, when the motor 210 is tilted upward, the crushing chamber 222 and the sewage outlet 221, which are arranged along the axis of the motor 210's rotational shaft, tilt upward simultaneously. In addition to the upper portion of the crushing chamber 222 being higher than the sewage outlet 110, the upper portion of the sewage outlet 221 is further higher than the crushing chamber 222. This creates a barrier between the crushing chamber 222, the sewage outlet 221, and the sewage outlet 110. If more water is introduced into the toilet, this area can also be used to contain water for a water seal.

[0116] As another optional solution, the motor 210 is tilted downward so that the upper part of the sewage cavity 221 is higher than the sewage outlet 110, forming a barrier between the two, and accommodating water in the area for water sealing, thereby blocking the air from communicating.

[0117] As another optional solution, the motor 210 is arranged horizontally so that the upper part of the sewage cavity 221 is higher than the sewage outlet 110, forming a barrier between the two, and accommodating water in the area for water sealing, thereby blocking the air connection.

[0118] Other optional solutions will not be described in detail in this embodiment.

[0119] Since when the motor 210 is not working, the sewage pump 200 can be regarded as a channel connected at both ends, and a barrier is formed inside it, so that the low-water-consumption toilet of the present application does not need to be water-sealed through a special elbow. After the water enters the sewage pump 200 from the pump inlet 230 through the sewage outlet 110 of the toilet 100, it is retained in the barrier. The water in the sewage pump 200 forms a static water column. When the sewage pump 200 is not working, the liquid will not flow out due to gravity, thereby preventing the backflow of odor, greatly saving water, and reducing the burden on users to clean the sewage storage tank.

[0120] In some cases, after the liquid flows back from the sewage pump 200 into the toilet bowl 100, it may also form a certain amount of accumulated water, reducing the adhesion of dirt in the toilet bowl 100, making the toilet bowl 100 easier to clean.

[0121] Preferably, Figure 16 As shown, the motor 210 is tilted upward on the side away from the urinal 100. The angle between the motor 210's rotation axis and the horizontal direction ranges from 0 to 65 degrees, with angles α of 10 degrees, 16 degrees, 30 degrees, 34 degrees, or 46 degrees, for example. Compared to a case where the motor 210 is tilted downward on the side away from the urinal 100, the urinal 100 can be sealed with a smaller amount of water, further improving its water conservation capabilities. Specifically, horizontally, the top of the sewage chamber 221 is higher than the top of the sewage outlet 110.

[0122] Optional, such as Figure 17 As shown, the motor 210 is tilted downwardly away from the side of the toilet 100, and the angle between the rotating axis of the motor 210 and the horizontal direction ranges from 0 to 20°. For example, the angle α is 5°, 8°, 15°, 17° or 19°. This arrangement utilizes the gravity of the waste to a certain extent, making it easier for the sewage pump 200 to absorb the waste. If the above numerical value exceeds the limited range, the water consumption of the water seal will increase.

[0123] Since the sewage outlet 110 is roughly arranged horizontally, it can prevent water from flowing out when combined with the sewage pump 200 which is also arranged horizontally or inclined. The connecting piece 600 only needs to firmly connect the two, so that the connecting piece 600 can be as short as possible. There is no need to set up too many bending structures to connect the sewage to the sewage pump 200, thereby achieving a water-saving function.

[0124] In this application, the terms "installed," "disposed," "provided with," "connected," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0125] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
