Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to an intelligent seasoning dispensing device. Background Technology

[0002] In the food processing industry, ensuring the accurate addition of seasonings such as salt and cooking oil is a crucial basic requirement. Currently, the main methods used are weighing equipment and manual estimation; however, these methods are cumbersome, inefficient, and lack precision. For example, restaurants or small food processing shops often rely on estimation to add salt and cooking oil in order to save time, which frequently leads to overuse or underuse. Therefore, finding a more convenient and efficient method for adding seasonings is particularly important.

[0003] Chinese utility model patent CN211155442U discloses a salt bottle for single-quantity salt dispensing. This design uses a rotary feeder; each press of a button activates the feeder, ensuring a consistent amount of salt enters and exits one compartment of the feeder each time. The amount of salt dispensed is controlled by the number of button presses. However, this invention requires manual button pressing, which can be limiting, slow, or inefficient in high-temperature, low-temperature, polluted, or hazardous environments. Furthermore, this single-quantity (multi-stage) salt dispensing method is unsuitable for industrial production requiring continuous and large-scale powder dispensing. Chinese utility model patent CN219688030U discloses an oil control spray head that is installed on an oil bottle and draws oil from the bottle by pressing. The oil is sprayed out from the nozzle through a suction tube assembly. The amount of oil drawn is the same with each press. The nozzle is extended and set inside the housing. This patent has a narrow scope of application, only solving a specific problem, namely the control problem when pouring oil from an oil bottle. Moreover, the design of the spray head is prone to oil splashing and waste, and manual pressing is relatively cumbersome. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a highly accurate and intelligent seasoning dispensing device for providing precise and intelligent quantitative dispensing of seasonings such as oil and salt to meet the needs of different application scenarios.

[0005] To achieve the above objectives, the present invention provides an intelligent seasoning dispensing device, comprising a main body shell and a liquid outlet and a powder outlet formed on the main body shell. The liquid outlet is used for dispensing liquid seasonings, and the powder outlet is used for dispensing fixed seasonings. The liquid outlet is connected to a liquid dispensing module, and the powder outlet is connected to a powder dispensing module. The liquid dispensing module is used for quantitative dispensing of liquid seasonings, and the powder dispensing module is used for quantitative dispensing of powdered seasonings.

[0006] The main body shell is also equipped with a display control module and a sensor. The display control module is used to set the dispensing amount of the fixed seasoning and the liquid seasoning, and to display the dispensing amount. The sensor is used to detect the container and the direction in which the container approaches, so as to switch the seasoning dispensing mode.

[0007] Furthermore, the liquid dispensing module includes a storage tank and a peristaltic pump. The storage tank is used to store liquid seasonings, one end of the peristaltic pump is connected to the stored liquid, and the other end of the peristaltic pump is connected to the liquid outlet.

[0008] Furthermore, the powder dispensing module includes a powder tank and a powder metering component. The powder tank is used to store powdered seasonings, and the powder metering component is located at the bottom of the powder tank for dispensing powdered seasonings in a metered manner. The powder metering component is connected to the powder outlet.

[0009] Furthermore, multiple liquid storage tanks and multiple powder tanks are provided, and the peristaltic pump is provided in a one-to-one correspondence with the liquid storage tank, and the powder metering component is provided in a one-to-one correspondence with the powder tank.

[0010] Furthermore, the powder metering component includes a discharge device, a stirrer, and a discharge baffle. The discharge device is provided with a discharge trough, the stirrer is located above the discharge device, and the discharge baffle is located below the discharge device. The discharge baffle is provided with a baffle slot, which is used to allow the powdered seasoning in the discharge trough to fall further downward. The discharge device is fixedly installed, and the stirrer rotates synchronously with the discharge baffle. The stirrer is located directly above the baffle slot and is correspondingly positioned to the baffle slot. The stirrer and the discharge baffle are connected by a rotating shaft, which movably passes through the through hole of the discharge device. The rotating shaft is connected to a powder driving component, which is used to drive the discharge baffle to rotate by a preset angle.

[0011] Furthermore, the powder driving assembly includes a ratchet disc and a pawl. The ratchet disc is positioned directly above the discharge baffle and is rotatably connected to the rotating shaft. The ratchet disc cooperates with the pawl. The ratchet disc has a ratchet disc slot corresponding to the baffle slot. The ratchet disc also has a movable groove. The discharge baffle has a protrusion that slides within the movable groove. The protrusion cooperates with the movable groove to switch the ratchet disc slot from coinciding with the baffle slot to not coinciding with it.

[0012] Furthermore, the powder driving assembly includes a drive motor, a drive gear, and a driven gear. The drive gear is mounted on the output shaft of the drive motor, and the driven gear is mounted on the rotating shaft and meshes with the drive gear.

[0013] Furthermore, the discharge trough is provided with baffles, and multiple baffles are provided and distributed symmetrically in a ring with respect to the center of the discharge trough. The baffles are arc-shaped, and the thickness of the baffles is equal to that of the center of the discharge trough in the normal direction. The root of the previous baffle and the top of the next baffle are on the same radial direction, so that during the rotation of the discharge baffle, there is always a baffle that passes through the baffle slot.

[0014] Furthermore, the display control module includes a switch and a display screen, the display screen being a touch screen used to display and control the amount of seasoning to be dispensed, and the switch used to initiate the dispensing of seasoning.

[0015] Furthermore, multiple sensors are set up. When the container is placed from left to right, the left sensor detects the container first compared to the right sensor, indicating that the container is moving from left to right. When the container is placed from right to left, the right sensor detects the container first compared to the left sensor, indicating that the container is moving from right to left. When all photoelectric sensors detect the container at the same time, it indicates that the container is placed from front to back, thereby switching between different delivery modes.

[0016] The above-described solution of the present invention has the following beneficial effects:

[0017] The intelligent seasoning dispensing device provided by this invention can accurately dispense liquid and powdered seasonings. Based on a precise quantitative system and control of driving elements, it ensures that different types of seasonings can be dispensed in a quantitative and continuous manner, thereby ensuring that the seasoning is dispensed consistently each time. Whether in home cooking or commercial food seasoning, it can ensure the consistency of seasoning and improve work efficiency.

[0018] The device provided by this invention includes a setting button, display screen, and sensors, which can quickly set and display the seasoning dispensing amount in real time, start up quickly, and accurately obtain information such as the direction in which the container approaches, so as to automatically select the correct dispensing mode, further improving the user experience.

[0019] In this invention, the powder metering component uses a stirrer located above the discharge device and a discharge baffle located below the discharge device. The stirrer and the discharge baffle move synchronously, so that the pressure of the powdered seasoning flowing between the discharge baffle and the stirrer is approximately the same. When the discharge baffle rotates, the density of the powdered seasoning remains basically unchanged, so that the mass of the discharged powder is proportional to its volume. That is, by using the volume method principle, precise metering of powdered seasoning is achieved. This method avoids the errors that may occur in the traditional gravimetric method, improves the accuracy of the ingredients, and the mass of the discharged material is only related to the rotation angle of the discharge baffle. Therefore, under the precise control of the rotation angle, continuous metering can be achieved.

[0020] Other beneficial effects of the present invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0030] To make the technical problems, solutions, and advantages of this invention clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0031] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a locking 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 invention based on the specific circumstances.

[0033] like Figure 1 , Figure 2 As shown, an embodiment of the present invention provides an intelligent seasoning dispensing device, including a main shell. The main shell is C-shaped and includes a top 1, a support column 2, and a bottom 3. A liquid storage tank 4 is disposed inside the main shell for storing liquid seasonings such as edible oil. A powder storage tank 5 is also disposed inside the main shell for storing powdered seasonings such as salt. In a preferred embodiment, two liquid storage tanks 4 and two powder storage tanks 5 are provided. The liquid storage tanks 4 can store edible oil, soy sauce, etc., respectively, while the powder storage tanks 5 can store salt, monosodium glutamate, etc., respectively, meeting the needs of restaurants or small food processing shops. Of course, if the internal space of the main shell allows, more liquid storage tanks 4 and powder storage tanks 5 can be arranged to meet a wider range of food processing and seasoning needs.

[0034] Correspondingly, the main body shell is also provided with a liquid outlet 6 and a powder outlet 7, with the liquid outlet 6 corresponding one-to-one with the liquid storage tank 4, and the powder outlet 7 corresponding one-to-one with the powder container 5, so that liquid seasonings and powdered seasonings are discharged from the liquid outlet 6 and the powder outlet 7 respectively. As a preferred embodiment, the liquid outlet 6 and the powder outlet 7 are both arranged on the lower surface of the top 1 of the shell. When adding, a bowl or other container is placed on the bottom 3 of the shell, and the seasonings discharged from the liquid outlet 6 and the powder outlet 7 fall directly into the container to complete the addition, which is convenient to operate.

[0035] In this embodiment, the liquid seasoning is driven and quantitatively delivered by a peristaltic pump 8. Specifically, the peristaltic pump 8 is installed inside the main casing. One end of the peristaltic pump 8 is connected to the storage tank 4 to draw the liquid seasoning from the storage tank 4, and the other end of the peristaltic pump 8 is connected to the outlet 6 to drive the liquid seasoning out of the outlet 6 and into the container below. It should be noted that the peristaltic pump 8 itself can adopt a structure from the prior art, which has advantages such as high precision and strong stability, ensuring continuous quantitative dispensing of the liquid seasoning. Obviously, multiple peristaltic pumps 8 are also provided, each corresponding one-to-one with the storage tank 4, to dispense specific amounts of different types of liquid seasoning, and to avoid the liquid seasoning from being mixed internally, thus preventing any impact on quantitative accuracy.

[0036] At the same time, such as Figure 3 As shown, in this embodiment, powdered seasonings need to be metered using a powder metering component, which employs a different principle than the metering of liquid seasonings. Specifically, the powder metering component includes a discharge device 9, a stirrer 10, and a discharge baffle 11. The discharge device 9 has a circular discharge trough. The stirrer 10 is positioned above the discharge device 9 and can rotate relative to it. The discharge baffle 11 is positioned below the discharge device 9 and can also rotate relative to it. The discharge baffle 11 has a fan-shaped baffle slot 12, which allows the powdered seasoning in the discharge trough (between the stirrer 10 and the discharge baffle 11) to further descend. The discharge device 9 is fixed, while the stirrer 10 and the discharge baffle 11 rotate synchronously via a connected rotating shaft 13, which movably passes through a through-hole in the discharge device 9. Meanwhile, the agitator 10 is located directly above and corresponding to the baffle slot 12, preventing powder above the agitator 10 from falling directly from the baffle slot 12. Additionally, multiple baffles 14 are installed within the discharge trough, arranged symmetrically in a ring shape relative to the center of the trough. These baffles 14 divide the discharge trough into multiple powder compartments, ensuring uniform and stable pressure of the powdered seasoning within each compartment during quantitative discharge, thereby further improving quantitative accuracy.

[0037] The powder dispensing component employs an automatic dispensing method. The dispensing baffle 11 is connected to the powder driving component, which drives the dispensing baffle 11 to rotate by a preset angle to complete the dispensing. Specifically, in this embodiment, the powder driving component includes a drive motor 15, a driving gear 16, and a driven gear 17. The driving gear 16 is mounted on the output shaft of the drive motor 15, and the driven gear 17 is mounted on the rotating shaft 13 and meshes with the driving gear 16. Therefore, when the dispensing baffle 11 needs to rotate by a corresponding angle θ1, the drive motor 15 only needs to rotate by a corresponding angle θ2 based on the ratio of the driving gear 16 to the driven gear 17 to achieve the purpose of dispensing.

[0038] As described above, to ensure the accuracy of powdered seasonings, it is necessary to ensure that the discharge baffle 11 rotates at different angles to accurately correspond to different amounts of discharge, so as to achieve precise quantitative dispensing of powdered seasonings in a continuous manner. The basic principle is to control the volume of powdered seasonings to achieve quantitative dispensing and metering. The specific theory is as follows:

[0039] like Figure 4 As shown, let the rotation angle of the discharge baffle 11 be θ1, and let r a r b These are the radii of the outer and inner circles of the discharge trough, respectively. According to the formula for calculating the area of ​​a sector, the hollow area swept by the discharge baffle 11 at this time is:

[0040]

[0041] At the same time, such as Figure 5 As shown, for the baffle 14 inside the discharge trough, taking the arc-shaped baffle 14 as an example, let its thickness be d(θ,r), where θ and r are the arc angle of the baffle 14 and its position relative to the center of the discharge trough, respectively. Then, the effective hollow area swept by the discharge baffle 11 is:

[0042]

[0043] If S′ is required to remain constant for any θ, r, i.e., d is a constant (normal to the center of the discharge trough), then it is required that...

[0044] d(θ,r)=f1(θ,r)-f2(θ,r)=C(3)

[0045] Where f1(θ,r) and f2(θ,r) are the inner curve function and outer curve function of partition 14, respectively, and C is a constant.

[0046] Let the height of the discharge trough be h, and the density of the powdered seasoning under a certain pressure be ρ(p), then the mass of the powdered seasoning corresponding to the rotation is:

[0047]

[0048]

[0049] Here, f(p) is a function that is related to p and independent of θ1, so it can be obtained through polynomials, spline fitting, etc.

[0050] In the above formula, θ1, r a r b The quality is related to processing accuracy; when the processing accuracy is sufficient, the error can be ignored. Therefore, the spatial structure model of the powdered seasoning flow and the influence of density ρ(p) on quality under different pressures are mainly considered.

[0051] Due to gravity, powdered seasonings exhibit a landslide effect at the edges, creating a repose angle. However, the landslide path is usually symmetrical, with both sides canceling each other out; therefore, its impact on volume is not considered here. Thus, the primary focus is on the effect of density ρ(p) on mass under different pressures. The loose and compaction densities of powdered seasonings have been extensively studied. Their density is related to particle size, compaction pressure, and porosity, and the relationship is relatively complex. To simplify calculations, we assume that particle size, compaction pressure, and porosity do not change significantly, and let their variation be Δρ.

[0052] Δq=((S′(θ1)+ΔS′(θ1))*h*(ρ+Δρ)-S′(θ1)*h*ρ

[0053] ≈S′(θ 1a )(hΔρ)+ΔS′(θ1)(hρ)(5)

[0054] In other words, the quality error is mainly related to manufacturing precision and variations in the density of the powdered seasoning. If the influence of manufacturing precision is ignored, the above formula approximates...

[0055] Δq≈S′(θ1)(hΔρ) (6)

[0056] Therefore, in order to achieve accurate quantification, the baffle 14 in the discharge tank needs to satisfy equation (3), or the thickness of the baffle 14 needs to be very thin (the normal thickness is approximately constant) to reduce the influence of the width of the baffle 14 on accurate discharge. At the same time, the agitator 10 and the discharge baffle 11 rotate synchronously. The powdered seasoning falling between the agitator 10 and the discharge baffle 11 does not move. The relative sliding between the discharge baffle 11 and the powdered seasoning only has a slight effect on the density of the bottom of the powdered seasoning. The pressure of the powdered seasoning between the discharge baffle 11 and the agitator 10 is approximately the same. The agitator 10 can stir the powdered seasoning above, so that the powdered seasoning is evenly distributed and the pressure is consistent with the powdered seasoning entering the area below the agitator 10, which further improves the accuracy of discharge.

[0057] It should be noted that the partition 14 is arranged in an arc shape, so that the root of the previous partition 14 and the top of the next partition 14 are on the same straight line (radial). This ensures that during the rotation relative to the discharge baffle 11 (the discharge baffle 11 rotates while the discharger 9 remains stationary), at least one partition 14 will always pass through the baffle groove 12, thus ensuring continuous and uniform discharge. Of course, in other embodiments, other forms can be used, as long as it is ensured that at least one partition 14 always passes through the baffle groove 12 during rotation.

[0058] When the discharge baffle 11 rotates at any angle θ1, the powdered seasoning falls through the baffle slot 12 of the discharge baffle 11 under the action of gravity. According to equation (4), the amount is only related to the rotation angle, and any angle can correspond to a precise discharge quality. Therefore, continuous and accurate quantitative measurement can be achieved through the precise control of the drive motor 15, ensuring the accuracy of the powdered seasoning fed from the powder outlet 7. As a preferred embodiment, the drive motor 15 in this embodiment can be in the form of a stepper motor, so as to achieve precise angle change through precise electrical pulse control, ensuring the stability and accuracy of each discharge. Relying on gear matching, the rotation of the stepper motor is converted into a smaller and finer turntable movement, ensuring the reliability of power transmission, while reducing noise and vibration. In actual use, the rotation angle of the stepper motor can be controlled by the system.

[0059] Among them, a guide 25 is also provided between the discharge baffle 11 and the powder outlet 7. The guide 25 is funnel-shaped to guide the powdered seasoning that falls from the baffle slot 12 at different positions during the rotation of the discharge baffle 11 to the powder outlet 7 and discharge it, so that it will not stay in other places and cause quantitative error.

[0060] At the same time, such as Figure 6As shown, as a further improvement, a ratchet disc 18 can be provided. The ratchet disc 18 is located directly above the discharge baffle 11 and is rotatably connected to the rotating shaft 13. The ratchet disc 18 cooperates with the pawl 19 to rotate in one direction. The ratchet disc 18 has a ratchet disc slot 20 corresponding to the baffle slot 12, and a movable groove 21 that cooperates with the protrusion 22 on the discharge baffle 11. When the discharge baffle 11 rotates, the protrusion 22 drives the ratchet disc 18 to rotate synchronously, and at this time, the baffle slot 12 and the ratchet disc slot 20 coincide, realizing the dispensing of powdered seasoning. After feeding, the drive motor 15 can drive the discharge baffle 11 to rotate in the opposite direction. The ratchet disc 18 will not rotate under the action of the pawl 19. The protrusion 22 on the discharge baffle 11 moves in the movable groove 21, so that the ratchet disc 18 does not overlap with the discharge groove of the discharge baffle 11. This prevents powdered seasoning from falling out when not in use, and allows for quick repositioning after use, preventing moisture, oil stains, etc. from entering the area above the discharge baffle 11 and causing the powdered seasoning to become damp. It is understood that when the drive motor 15 rotates to the corresponding angle, the rotation angle of the drive motor 15 needs to be controlled by electrical pulses during the next feeding process. This includes the angle of the previous rotation plus the angle required for feeding, which can be set by the system.

[0061] As a further improvement, in this embodiment, a soft pad can be provided on the surface between the ratchet disc 18 and the discharge baffle 11. Since the ratchet disc 18 needs to rotate at a certain angle relative to the discharge baffle 11, the soft pad prevents a small amount of powdery seasoning falling between the ratchet disc 18 and the discharge baffle 11 from forming hard friction, causing rotational jamming that affects the rotational accuracy of the structure, or grinding the powdery seasoning, thus further improving the reliability of the cooperation between the ratchet disc 18 and the discharge baffle 11. In addition, an additional baffle slot 12 can be provided on the discharge baffle 11. This baffle slot 12 is used to discharge a small amount of powdery seasoning between the ratchet disc 18 and the discharge baffle 11, so that it does not accumulate too much and cause rotational jamming.

[0062] Therefore, in this embodiment, the peristaltic pump 8 is controlled by the system to quantitatively dispense liquid seasonings, and the drive motor 15 is controlled by the system to quantitatively dispense powdered seasonings, thus achieving intelligent seasoning distribution. Multiple peristaltic pumps 8 and drive motors 15 are provided to correspond to different types of liquid and powdered seasonings. The system controls the corresponding peristaltic pumps 8 and drive motors 15 based on the parameters set by the user to quantitatively dispense different seasonings.

[0063] Please refer to it again. Figure 1 , Figure 2In this embodiment, a switch is also provided on the main body shell, preferably a contact micro switch 23, for touching and sensing signals to start the peristaltic pump 8 and drive motor 15 to discharge materials. At the same time, a display screen 24 is also provided on the main body shell, which can display the set dosage in real time, and can also be used as a touch screen to facilitate users to set and adjust the dosage of different seasonings.

[0064] In a preferred embodiment, the contact micro switch 23 is located on the front side of the outer casing support 2, allowing the user to directly touch the contact micro switch 23 to initiate the addition of seasonings after placing the container on the bottom 3 of the outer casing. The display screen 24 is located on the front side of the top 1 of the outer casing, allowing the user to directly view and touch-control parameter settings. Therefore, the human-computer interaction experience during use is guaranteed.

[0065] Understandably, in actual use, some foods may only require liquid seasoning, while others may only require powdered seasoning. For other foods, both types of seasoning need to be added, and frequent switching is required throughout the process. Switching via the 24-hour touchscreen display each time would be cumbersome. Therefore, this embodiment also includes a photoelectric sensor on the main casing, which can be located at the top 1 and / or the uprights 2 and / or the bottom 3 of the casing. This sensor detects whether a container is approaching and the direction of that approach, thereby switching the aforementioned dispensing mode.

[0066] For example, if the liquid outlet 6 is located on the left side of the device and the powder outlet 7 is located on the right side, when the user places the container from the left side of the device onto the bottom 3 of the outer casing, the photoelectric sensor detects that the container is moving from left to right, and the feedback system switches to controlling only the peristaltic pump 8 for quantitative dispensing. When the user places the container from the right side of the device onto the bottom 3 of the outer casing, the photoelectric sensor detects that the container is moving from right to left, and the feedback system switches to controlling only the drive motor 15 for quantitative dispensing. When the user places the container from front to back onto the bottom 3 of the outer casing, the photoelectric sensor detects that the container is moving from front to back, and the feedback system switches to controlling both the peristaltic pump 8 and the drive motor 15 for quantitative feeding. This method corresponds to the placement positions of the liquid outlet 6 and the powder outlet 7, thus better matching the user's placement actions and minimizing errors during high-frequency use.

[0067] Multiple photoelectric sensors can be arranged sequentially along the left and right sides of the device. When the user places the container onto the bottom 3 of the outer casing from left to right, the photoelectric sensor on the left detects the container before the photoelectric sensor on the right. That is, when the photoelectric sensors detect the container sequentially from left to right, it indicates that the container is moving from left to right, and vice versa. When all (or most) of the photoelectric sensors detect the container simultaneously, it indicates that the container is placed onto the bottom 3 of the outer casing from front to back. Therefore, the system can accurately obtain the container's approach direction information, ensuring that the correct dispensing mode is selected.

[0068] Of course, the approach direction confirmed by photoelectric sensors may still have judgment errors. Therefore, to ensure the correctness of the delivery mode, it is best to display the delivery mode on the display screen 24 in real time so that users can confirm that the delivery mode is correct. When the delivery mode is incorrect, users can also manually switch the delivery mode on the display screen 24 by touch.

[0069] As described above, the intelligent seasoning dispensing device provided in this embodiment can automatically dispense liquid seasonings such as cooking oil and powdered seasonings such as salt. It also has multiple dispensing modes and a very reasonable human-computer interaction design, which can meet the diverse needs of different users and ensure the user experience.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
