Description

Technical Field

[0001] This utility model relates to the field of pet water dispenser technology, and in particular to a pet water dispenser that separates clean water from dirty water. Background Technology

[0002] Pet water fountains are essential equipment in modern pet ownership, primarily providing convenient drinking water and ensuring the cleanliness and hygiene of the water source. Traditional pet water fountains typically have only one water tank for storing and supplying water. A major problem with this design is that pets may bring hair, food scraps, and other impurities into the tank while drinking. These impurities mix with the water, affecting water quality and potentially creating a breeding ground for bacteria. Furthermore, because they cannot effectively separate clean and dirty water, traditional water fountains require frequent overall cleaning, increasing the maintenance burden on users and potentially leading to further water quality deterioration if cleaning is not timely. To achieve separation of clean and dirty water, some pet water fountains on the market have attempted to use additional filtration devices or separation structures. However, these attempts often have several shortcomings. For example, while some filtration devices can remove some impurities, they cannot completely solve the problem of separating larger particles such as hair; and some separation structures may not be widely adopted due to their complex design, difficult maintenance, or poor performance. Utility Model Content

[0003] The present invention provides a pet water dispenser that separates clean and dirty water, thereby providing a healthier and more convenient drinking environment for pets.

[0004] First aspect

[0005] This utility model discloses a pet water dispenser that separates cleanliness and dirt, including: a water purification device with a water purification tank, wherein the water purification device is provided with a first magnetic suction part;

[0006] A wastewater tank is located on one side of the water purification device and near the first magnetic suction part, and the wastewater tank has a wastewater trough;

[0007] A water tray, located on the same side of the water purification device as the wastewater tank, has a drinking trough and a drain hole connected to the drinking trough. The water tray covers the opening of the wastewater tank, and the drinking trough is connected to the wastewater tank through the drain hole. The water tray is provided with a second magnetic suction part.

[0008] A power supply component is installed in the water purification device in a water-proof manner. The power supply component includes a main board, a control unit electrically connected to the main board, and a first conductive structure.

[0009] A water pump is installed in the water purification device and electrically connected to the main board. The input end of the water pump is connected to the water purification tank, and the output end of the water pump extends out of the water purification device and is located above the drinking water tank.

[0010] A circulation pump is located on the side of the water pan facing away from the drinking trough and is electrically connected to the first conductive structure through a second conductive structure. Both the input and output ends of the circulation pump are connected to the drinking trough.

[0011] When the water tray approaches the water purification device, the first magnetic attraction part and the second magnetic attraction part are aligned and magnetically attracted, and at the same time the first conductive structure and the second conductive structure are electrically connected.

[0012] In one embodiment, the water purification device includes a purified water tank and a supporting vertical plate, wherein the purified water tank and the wastewater tank are respectively disposed on opposite sides of the supporting vertical plate;

[0013] The water purification tank is formed in the water purification tank, and the first magnetic suction part is provided on the side of the support vertical plate facing the sewage tank; the support vertical plate is provided with a mounting cavity for accommodating and fixing the power supply component and the water pump, and the output end of the water pump passes through the mounting cavity and out of the support vertical plate.

[0014] In one embodiment, the first conductive structure includes a first conductive post, one end of which is electrically connected to the main board, and the other end of which passes through the support vertical plate and is exposed. The second conductive structure includes a second conductive post, one end of which is electrically connected to the circulation pump, and the other end of which passes through the water tray and is exposed.

[0015] The magnetic attraction between the first magnetic attraction part and the second magnetic attraction part is parallel to the axial direction of the first conductive column. When the water tray is close to the support vertical plate, the magnetic attraction between the first magnetic attraction part and the second magnetic attraction part drives the first conductive column to make electrical contact with the second conductive column.

[0016] In one embodiment, one of the two contact surfaces of the support plate and the water tray that are magnetically attracted to each other is provided with a positioning protrusion, and the other is provided with a positioning groove. The first conductive post and the second conductive post are respectively exposed on the upper surface of the positioning protrusion and the bottom wall of the positioning groove. When the water tray is close to the support plate, the magnetic attraction of the first magnetic part and the second magnetic part drives the positioning protrusion to be aligned and engaged in the positioning groove, and at the same time the first conductive post and the second conductive post make electrical contact.

[0017] In one embodiment, both the first magnetic attraction part and the second magnetic attraction part are magnetic blocks. The water purification device has a first placement groove on the side facing the water tray for accommodating the first magnetic attraction part, and the water tray has a second placement groove for accommodating the second magnetic attraction part.

[0018] In one embodiment, the first magnetic attraction part is a magnet block, the second magnetic attraction part and part of the water tray are integrally formed metal blocks, and the water purification device has a placement groove on the side facing the water tray for the first magnetic attraction part to be accommodated.

[0019] Alternatively, the second magnetic attraction part is a magnet block, and the first magnetic attraction part and part of the structure of the water purification device are integrally formed metal blocks, and the water tray is provided with a placement groove for accommodating the second magnetic attraction part on the side facing the water purification device.

[0020] In one embodiment, the number of the first magnetic attraction parts is two and they are arranged symmetrically with respect to the first conductive structure; the number of the second magnetic attraction parts is two and they are arranged symmetrically with respect to the second conductive structure.

[0021] In one embodiment, the upper end of the water purification device protrudes towards the side of the sewage tank to form a mounting platform, and the mounting platform is located vertically directly above the drinking water trough.

[0022] The mounting platform has a first surface and a second surface connected at an angle on the side facing away from the water trough. The first surface is vertically opposite to the drinking water trough, and the output end of the water pump extends out of the first surface. The control unit includes a control panel, which is embedded in the second surface.

[0023] In one embodiment, the control unit includes a camera module, which includes a camera electrically connected to a control chip. The camera is embedded in the outer wall of the water purification device facing the water tray, and is located above the water tray. The control chip is integrated on the motherboard, and both the water pump and the circulation pump are electrically connected to the control chip.

[0024] When the camera detects that the straight-line distance between the pet and the clean and dirty pet water fountain is within the target range, the control chip controls the water pump and the circulation pump to turn on, so as to replenish the water tank and start water circulation;

[0025] When the camera detects that the straight-line distance between the pet and the pet water fountain is outside the target range, the control chip controls the disconnection of the water pump and the circulation pump to stop replenishing water to the water tank and disconnect the water circulation.

[0026] In one embodiment, the pet water fountain includes a support plate, on which the water purification device and the wastewater tank are mounted side-by-side and pressed together; the support plate has a built-in load sensor, which is electrically connected to the main board, and is used to monitor the water volume in the water purification device and the wastewater tank.

[0027] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0028] This utility model provides a pet water fountain with clean and dirty water separation, including a water purification device, a dirty water tank, and a water tray. The water purification device contains clean water, and the dirty water tank and water tray are located on the same side of the water purification device. The water tray is covered above the dirty water tank. A circulation pump is activated to circulate the water in the water tray, creating a flowing water environment. The dirty water tank collects the dirty water from the water tray. The separate arrangement of the water purification device and the dirty water tank achieves clean and dirty water separation. The water tray is magnetically attached to one side of the water purification device and electrically connected to the circulation pump in the water tray via a first conductive structure and a second conductive structure. The control unit on the power supply component can control the operation of both the water pump and the circulation pump. Here, the magnetic attachment enhances the assembly stability of the water tray and the water purification device, and also allows the first and second conductive structures to automatically align and connect, improving the stability of the electrical connection. Furthermore, the water tray is easy to assemble and disassemble, and the circulation pump can be quickly switched on and off, improving the overall electrical safety of the pet water fountain. The pet water fountain with clean and dirty water separation of this application has a compact and stable assembly, is electrically safe, and has strong practicality. Attached Figure Description

[0044] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] Reference Figure 1-3 This application provides a novel pet water fountain 1 with separate clean and dirty water compartments. The pet water fountain 1 has two water tanks, one for storing clean water and the other for collecting dirty water, effectively separating clean and dirty water to ensure clean and hygienic drinking water for pets. The pet water fountain 1 includes a detachable water purification device 10, a dirty water tank 20, and a water tray 30. The water purification device 10 has an electrically connected power supply component 40 and a water pump 50. The water pump 50 draws clean water from the water purification device 10 into the water tray 30 for the pet to drink from. The dirty water tank 20 collects dirty water generated by the pet during drinking. The separate arrangement of the water purification device 10 and the dirty water tank 20 achieves clean and dirty water separation. The water tray 30 has a circulation pump 60. When the circulation pump 60 is turned on, the water in the water tray 30 circulates to maintain the vitality of the drinking water and increase the pet's interest in drinking.

[0048] Continue to refer to Figure 1-3The water purification device 10 has a water purification tank 111 for storing clean water. A first magnetic suction part 12 is provided on one side of the water purification device 10. A wastewater tank 20 is located on one side of the water purification device 10 and close to the first magnetic suction part 12. The wastewater tank 20 has a wastewater trough 21 for collecting and storing dirty water produced by the pet during drinking. A water tray 30 is located on the same side of the water purification device 10 as the wastewater tank 20. The water tray 30 has a drinking trough 31 and a drain hole 311 connecting to the drinking trough. The water tray 30 covers the opening of the wastewater trough 21, and the drinking trough 31 is connected to the wastewater trough 21 through the drain hole 311. The water tray 30 is provided with a second magnetic suction part 32. The drinking trough 31 is used to hold drinking water for the pet. If the water in the drinking trough 31 is soiled by the pet, it can leak into the wastewater trough 21 through the drain hole 311. The drain hole 311 is generally located at the bottom of the wastewater trough 21 to allow the dirty water in the drinking trough 31 to drain out. The power supply component 40 provides power and is installed in the water purification device 10 in a water-proof manner. The power supply component 40 includes a main board 41, a control unit 42 electrically connected to the main board 41, and a first conductive structure 43.

[0049] Reference Figure 2-4 A water pump 50 is located in the water purification device 10 and electrically connected to the main board 41. The first input terminal 51 of the water pump 50 is connected to the water purification tank 111 via a water pipe. The first output terminal 52 of the water pump 50 extends out of the water purification device 10 via a water pipe and is located above the drinking trough 31. When the water pump 50 is started, it drives the clean water source in the water purification tank 111 to be introduced into the drinking trough 31 through the first input terminal 51 and the first output terminal 52 of the water pump 50 for the pet to drink. A circulation pump 60 is located on the side of the water tray 30 facing away from the drinking trough 31 and is electrically connected to the second conductive structure 33. The second conductive structure 33 is electrically connected to the first conductive structure 43, and the first conductive structure 43 is electrically connected to the main board 41, thus the circulation pump 60 is electrically connected to the main board 41. The second input terminal 61 and the second output terminal 62 of the circulation pump 60 are both connected to the drinking tank 31. When the circulation pump 60 is started, the water in the drinking tank 31 is driven to return to the drinking tank 31 after passing through the second input terminal 61 and the second output terminal 62 of the circulation pump 60, thus realizing water circulation.

[0050] Reference Figure 5 and Figure 6 When the water tray 30 approaches the water purification device 10, the first magnetic attraction part 12 and the second magnetic attraction part 32 are aligned and magnetically attracted, and at the same time, the first conductive structure 43 and the second conductive structure 33 are electrically connected.

[0051] The pet water fountain 1 provided by this utility model separates the water purification device 10 and the wastewater tank 20 to achieve separation of clean and dirty water, ensuring the cleanliness and hygiene of the pet's drinking water source. The water tray 30 is installed on one side of the water purification device 10 via magnetic attraction (first magnetic attraction part 12 and second magnetic attraction part 32), and is electrically connected to the circulation pump 60 in the water tray 30 through the first conductive structure 43 and the second conductive structure 33. The control unit 42 on the power supply component 40 can then control the working status of the water pump 50 and the circulation pump 60. Here, the magnetic installation enhances the assembly stability between the water tray 30 and the water purification device 10, and also allows the first conductive structure 43 and the second conductive structure 33 to automatically align and connect via magnetic attraction, improving the stability of the electrical connection. The water tray 30 is easy to install and remove, and the circulation pump 60 can be quickly switched on and off, thereby improving the electrical safety of the entire pet water fountain 1. The pet water fountain 1 with clean and dirty water separation of this application has a compact and stable assembly, is electrically safe, and has strong practicality.

[0052] Preferably, combined with Figure 1-3 In one embodiment, the water purification device 10 includes a purified water tank 11 and a supporting vertical plate 13, with the purified water tank 11 and the wastewater tank 20 respectively located on opposite sides of the supporting vertical plate 13. A purified water trough 111 is formed in the purified water tank 11, and a first magnetic suction part 12 is located on the side of the supporting vertical plate 13 facing the wastewater tank 20. The supporting vertical plate 13 is provided with a mounting cavity 131 for accommodating and fixing the power supply component 40 and the water pump 50. The first output end 52 of the water pump 50 extends out of the supporting vertical plate 13 from the mounting cavity, and discharges the clean water in the purified water trough 111 into the drinking water tank 31. It can be understood that the water purification device 10 is configured as two independently isolated chambers, namely the purified water trough 111 and the mounting cavity 131. The purified water trough 111 contains a clean water source, and the mounting cavity 131 accommodates and fixes the power supply component 40 and the water pump 50.

[0053] In this embodiment, the water tank 11 and the supporting vertical plate 13 can be independently configured as two detachably connected box structures, enhancing water resistance and facilitating electrical maintenance. Furthermore, the mounting cavity 131 in the supporting vertical plate 13 can independently accommodate the piping distribution related to the power supply component 40 and the water pump 50. In other embodiments, the water tank 11 and the supporting vertical plate 13 can be integrally formed, sharing a side plate to separate the water tank 111 and the mounting cavity 131. In yet another embodiment, the supporting vertical plate 13 is not required; the power supply component 40 and the water pump 50 can be directly installed on the outside of the water tank 11 in a water-resistant manner. Therefore, in this application, the presence, state, and position of the supporting vertical plate 13 are not limited.

[0054] Preferably, in conjunction with reference Figure 5 and Figure 6In one embodiment, the first conductive structure 43 includes a first conductive post 431, one end of which is electrically connected to the main board 41, and the other end of which is exposed through the supporting vertical plate 13. The second conductive structure 33 includes a second conductive post 331, one end of which is electrically connected to the circulation pump 60, and the other end of which is exposed through the water tray 30. The magnetic attraction between the first magnetic attraction part 12 and the second magnetic attraction part 32 is parallel to the axial direction of both the first and second conductive posts 431. When the water tray 30 approaches the supporting vertical plate 13, the magnetic attraction between the first magnetic attraction part 12 and the second magnetic attraction part 32 drives the first conductive post 431 and the second conductive post 331 to approach each other and make electrical contact, so that the water tray 30 is magnetically attached to the supporting vertical plate 13, and at the same time, the electrical connection between the circulation pump 60 and the main board 41 is established. The two conductive posts approach each other along the axial direction and make contact at their ends to achieve electrical connection. It should be understood that in other embodiments, conductive posts are not required, and the first conductive structure 43 and the second conductive structure 33 can also be connected by metal springs to achieve contact electrical connection.

[0055] Preferably, in conjunction with reference Figure 6 and Figure 7 In one embodiment, at the contact surface where the supporting vertical plate 13 and the water tray 30 magnetically attract each other, a positioning protrusion 34 is provided on the magnetic surface of the water tray 30, and the second conductive post 331 is exposed on the upper surface of the positioning protrusion 34 (meaning the positioning protrusion 34 protrudes from the outer wall surface away from the outer side wall of the water tray 30); the magnetic surface of the supporting vertical plate 13 is provided with a positioning groove 14, and the first conductive post 431 is exposed on the bottom wall of the positioning groove 14. When the water tray 30 approaches the supporting vertical plate 13, the magnetic attraction force of the first magnetic part 12 and the second magnetic part 32 drives the positioning protrusion 34 to align and engage in the positioning groove 14, while the first conductive post 431 and the second conductive post 331 make electrical contact. The alignment and engagement of the positioning protrusion 34 and the positioning groove 14 not only enhances the assembly stability between the water tray 30 and the supporting vertical plate 13, but also improves the electrical contact stability between the first conductive post 431 and the second conductive post 331, while hiding and protecting the electrical contact position of the two, thus improving electrical safety. Furthermore, the positioning protrusion 34 and the positioning groove 14 are in a mating relationship; swapping their positions can achieve the same positioning and engaging effect. In another embodiment, the positioning protrusion 34 can protrude from the magnetic surface of the supporting vertical plate 13, and the positioning groove 14 can be located on the magnetic surface of the water tray 30. Of course, in other embodiments, the positioning groove 14 and the positioning protrusion 34 may not be necessary; the first conductive post 431 and the second conductive post 331 can still achieve electrical connection through alignment and contact driven by the magnetic attraction of the two magnetic parts.

[0056] Preferably, in conjunction with reference Figure 5 and Figure 6In one embodiment, both the first magnetic suction part 12 and the second magnetic suction part 32 are magnetic blocks. The water purification device 10 is provided with a first placement groove 15 for the first magnetic suction part 12 to be accommodated on the side facing the water tray 30, and the water tray 30 is provided with a second placement groove 35 for the second magnetic suction part 32 to be accommodated. Figure 3 As shown, the first magnetic suction part 12 and the first placement groove 15 are both located inside the mounting cavity 131, and the second magnetic suction part 32 and the second placement groove 35 are both located on the side of the water tray 30 facing away from the drinking water tank 31. At this time, the two magnet blocks corresponding to the first magnetic suction part 12 and the second magnetic suction part 32 are separated by the supporting vertical plate 13 and the outer shell of the water tray 30.

[0057] Optionally, in one embodiment (not shown), the first magnetic attraction part 12 is a magnet, and the second magnetic attraction part 32 and part of the structure of the water purifier 30 are integrally formed metal blocks. The water purification device 10 has a placement groove (first placement groove 15) on the side facing the water purifier 30 for accommodating the first magnetic attraction part 12. Alternatively, in one embodiment (not shown), the second magnetic attraction part 32 is a magnet, and the first magnetic attraction part 12 and part of the structure of the water purification device 10 are integrally formed metal blocks. The water purifier 10 has a placement groove (second placement groove 35) for accommodating the second magnetic attraction part 32.

[0058] It is understandable that when the two magnetic attracting parts are attracted to each other by two magnets, the materials of the water purification device 10 and the water tray 30 are not limited; when the two magnetic attracting parts are attracted to metal by one magnet, at least one of the water purification device 10 and the water tray 30 must have a portion of its structure made of metal. Therefore, in this application, the number of magnets and placement slots is not limited, and at least one set is sufficient. That is, at least one of the two magnetic attracting surfaces of the water purification device 10 and the water tray 30 is provided with a placement slot, which is used to place the first magnetic attracting part 12 or the second magnetic attracting part 32.

[0059] Preferably, in conjunction with reference Figure 5 and Figure 6 In one embodiment, there are two first magnetic suction parts 12, symmetrically arranged relative to the first conductive structure 43; there are also two second magnetic suction parts 32, symmetrically arranged relative to the second conductive structure 33. The symmetrical arrangement of the magnetic suction parts not only further enhances the assembly stability between the water tray 30 and the water purification device 10, but also greatly improves the electrical connection stability between the two conductive structures. Of course, in other embodiments, the number of first magnetic suction parts 12 and second magnetic suction parts 32 can also be one, arranged in a ring shape, surrounding the first conductive structure 43 and the second conductive structure 33 in the middle, which also improves assembly stability and electrical connection stability. Of course, provided the magnetic attraction between the two magnetic suction parts is strong enough, the number, shape, and arrangement of the first magnetic suction parts 12 and the second magnetic suction parts 32 are not limited.

[0060] Optionally, in conjunction with reference Figure 1 and Figure 7 In one embodiment, the upper end of the water purification device 10 protrudes to the side facing the sewage tank 20 to form a mounting platform 16, which is located vertically directly above the drinking trough 31. Figure 7 The mounting platform 16 has a first surface 161 and a second surface 162 connected at an angle on the side facing away from the water trough 111 (the side facing the wastewater trough 21). The first surface 161 is vertically opposite to the drinking trough 31. The first output end 52 of the water pump 50 extends out of the first surface 161. The clean water pumped by the water pump 50 falls into the drinking trough 31 under the action of gravity for the pet to drink. The first surface 161 can also effectively prevent the drinking water in the drinking trough 31 from splashing. In addition, the control unit 42 includes a control panel 421, which is electrically connected to the motherboard and embedded in the second surface 162 for convenient touch screen or button operation. It should be noted that in other embodiments, the water purification device 10 does not need to have a protruding mounting platform. The first output end 52 of the water pump 50 can extend out of the water purification device 10 and be connected to a water outlet pipe to guide clean water into the drinking trough 31; the control panel 421 can also be directly embedded in the top wall or outer wall of the water purification device 10. Therefore, in this application, there is no limitation on whether or not the mounting platform 16 is set up.

[0061] Preferably, in conjunction with reference Figure 2 , Figure 3 and Figure 7 In one embodiment, the control unit 42 includes a camera module 422, which includes a camera 422a electrically connected to a control chip (not shown). The camera 422a is embedded in the outer wall (second side 162) of the water purifier facing the water tray. The camera 422a is located above the water tray 30 and in front of the pet water fountain 1. The control chip is integrated on the motherboard 41, and the water pump 50 and the circulation pump 60 are electrically connected to the control chip. When the pet moves around the pet water fountain 1, the camera 422a works as follows: when the camera 422a detects that the straight-line distance between the pet and the pet water fountain 1 is within the target range, the control chip controls the water pump 50 and the circulation pump 60 to turn on. Both are in working condition to replenish water to the water tank 31 and start water circulation, providing the pet with clean, flowing drinking water. When camera 422a detects that the straight-line distance between the pet and the pet water fountain 1 is outside the target range, the control chip controls the disconnection of water pump 50 and circulation pump 60, both of which stop working to stop replenishing water to the water tank 31 and disconnect the water circulation. The camera module 422 effectively detects and controls the pet's drinking needs, realizing intelligent water dispensing from the pet water fountain 1. It should be noted that in other embodiments, the camera module 422 is not required, and the water dispensing from the pet water fountain can also be controlled by human monitoring.

[0062] Preferably, refer to Figure 4In one embodiment, the pet water fountain 1 includes a support plate 70, a water purification device 10, and a wastewater tank 20, which are mounted side-by-side on the support plate 70. The support plate 70 provides the mounting position for the water purification device 10 and the wastewater tank 20, further improving the compactness and stability of the entire pet water fountain 1. The support plate 70 has a built-in load-bearing sensor 71, which is electrically connected to the main board 41. The load-bearing sensor 71 detects the amount of water (i.e., the weight of the water) in the water purification device 10 and the wastewater tank 20, prompting the user to replenish the water purification device 10 with clean water or clean the wastewater tank 20. Multiple load-bearing sensors 71 are evenly distributed on the support plate 70. The user needs to place the entire pet water fountain 1 on a level surface to obtain accurate load-bearing data. The water volume detected by the load-bearing sensor 71 can be displayed on the control panel 421 for easy viewing by the user; alternatively, the load-bearing data can be transmitted wirelessly to a mobile terminal (e.g., a mobile phone) for easy viewing by the user.

[0063] It should be noted that in other embodiments, the supporting plate 70 is not provided, and the water purification device 10 and the wastewater tank 20 can be abutted together, with a positioning connection structure provided on the abutting surface to enhance assembly stability. In one embodiment, the load-bearing sensor 71 may also be omitted, and the water purification device 10 and the wastewater tank 20 are made transparent, allowing the water volume in the corresponding tank to be obtained by visual observation.

[0064] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
