[0050] Unless otherwise defined, the technical terms or scientific terms used herein should be understood as the usual meanings understood by those of ordinary skill in the art to which the present application belongs. The terms “first”, “second” and similar terms used in the specification and claims of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. Similarly, the terms “one” or “a” and similar terms do not necessarily represent a quantity limitation.

[0051] Please refer to Figures 1 to 11The embodiments of this application disclose an intelligent vending device that can perform IoT traceability of bulk liquid products. The liquid mentioned in the embodiments of this application can be bulk liquids such as bulk liquor, beer, wine, soy sauce, vinegar, cooking oil, bulk beverages, etc.

[0052] like Figure 1 , Figure 2 As shown, the smart vending device proposed in this application for IoT traceability of bulk liquid products includes a body 20 and a liquid acquisition mechanism 30 and a head 40 disposed on the body 20. Of course, it may also include a container 10.

[0053] Combination Figures 3 to 5 As shown, the container 10 includes a body 11 and a cover 12 connected to the body 11. The body 11 defines a holding cavity 1101 suitable for holding liquid, and the body 11 is provided with a first identification tag containing first identification information. The first identification tag is preferably disposed on the outer periphery of the body 11. It should be noted that the identification tag described throughout this application can be an RFID electronic tag, a QR code tag, or a barcode tag. Correspondingly, for the identification reading and writing device described below, when the identification tag is an RFID electronic tag, a QR code tag, or a barcode tag, the identification reading and writing device corresponds to an RFID reader, a QR code tag reader, or a barcode tag reader.

[0054] The cover 12 has a receiving cavity 1201, and the receiving cavity 1201 is provided with a ventilation port 13, a liquid outlet port 14, a liquid inlet port 15, a ventilation solenoid valve 16, a liquid outlet solenoid valve 17, and a liquid inlet solenoid valve 18. Among them, one end of the ventilation port 13, the liquid outlet port 14, and the liquid inlet port 15 are connected to the holding cavity 1101, and the other end of the ventilation port 13, the liquid outlet port 14, and the liquid inlet port 15 are respectively connected to one end of the ventilation solenoid valve 16, the liquid outlet solenoid valve 17, and the liquid inlet solenoid valve 18. The other end of the ventilation solenoid valve 16, the liquid outlet solenoid valve 17, and the liquid inlet solenoid valve 18 is respectively provided with a ventilation port 19, a liquid outlet port 110, and a liquid inlet port 111 extending outside the receiving cavity 1201. The receiving cavity 1201 is also provided with a solenoid valve power port 112 extending outside the receiving cavity 1201.

[0055] In this application, the ventilation port 13, the ventilation solenoid valve 16, and the ventilation inlet 19 are used in conjunction to achieve air exchange between the storage chamber 1101 and the external environment by appropriately opening and closing the ventilation solenoid valve 16 when adding liquid to or extracting liquid from the storage chamber 1101, thereby maintaining the air pressure in the storage chamber 1101 within a reasonable range. The liquid outlet port 14, the liquid outlet solenoid valve 17, and the liquid outlet inlet 110 are used to allow liquid to flow out of the storage chamber 1101. The liquid inlet port 15, the liquid inlet solenoid valve 18, and the liquid inlet 111 are used to allow liquid to enter the storage chamber 1101. For example, the licensor can fill the storage chamber 1101 with liquid using the liquid inlet 111. The solenoid valve power socket 112 is used to cooperate with the power supply interface 37, which will be described below. When the power supply interface 37 is connected to the solenoid valve power socket 112, the power supply interface 37 can supply power to the electrical components such as the ventilation solenoid valve 16, the liquid discharge solenoid valve 17, and the liquid inlet solenoid valve 18 in the receiving cavity 1201 through the solenoid valve power socket 112. The power supply interface 37 is electrically connected to the power supply in the body 20.

[0056] Furthermore, the cover 12 is provided with an openable and closable cover 113, which can be a component hinged to the cover 12. The cover 113 can be locked in the closed position by a controllable electronic lock 114, thus blocking the ventilation port 19, liquid outlet port 110, liquid inlet port 111, and solenoid valve power socket 112 extending outside the receiving cavity 1201. That is, when the cover 113 is closed, the ventilation port 19, liquid outlet port 110, liquid inlet port 111, and solenoid valve power socket 112 are all blocked and hidden. Simultaneously, the cover 113 is provided with a second identity tag containing second identity information, and the electronic lock 114 contains a third identity tag containing third identity information.

[0057] Furthermore, refer to Figure 3 As shown, the ventilation port 19, liquid outlet port 110, liquid inlet port 111 and solenoid valve power port 112 extending outside the accommodating cavity 1201 are all sealed by a disposable sealing cover 115, which is provided with a fourth identity label containing fourth identity information.

[0058] Combination Figure 2 As shown, the body 20 is provided with a storage cavity 21 suitable for storing the container 10. One side of the storage cavity 21 is provided with an openable and closable storage door 22, which may be a component hinged to the body 20. Furthermore, when the storage door 22 is locked in the closed position by a controllable storage door electronic lock 23, the storage door electronic lock 23 is provided with a container identification reading and writing device.

[0059] The container identity reading and writing device is configured to read or modify the first identity information of the first identity tag and the second identity information of the second identity tag, and the container identity reading and writing device can compare the read first identity information and second identity information with the first preset identity information respectively; and the first preset identity information is written into the container identity reading and writing device.

[0060] When the first identity information and the second identity information read by the container identity reading and writing device are matched with the first preset identity information, the storage door electronic lock 23 for locking the storage door 22 is unlocked. That is, in the actual use stage of the liquid Internet of Things traceability intelligent selling device, when the relevant personnel carry the container 10 to the intelligent selling device, the first identity information and the second identity information need to be read by the container identity reading and writing device first, and the first identity information and the second identity information are compared with the first preset identity information respectively. The first preset identity information can be liquid manufacturer information, etc.

[0061] On this basis, if the first identity information and the second identity information are matched with the first preset identity information, it means that the container 10 comes from the manufacturer, at this time, the storage door electronic lock 23 is unlocked to facilitate the opening of the storage door 22 to put the container 10 into the storage cavity 21 of the body 20. On the contrary, if one or both of the first identity information and the second identity information do not match the first preset identity information, it means that the container 10 does not come from the manufacturer, at this time, the storage door electronic lock 23 is not unlocked, and the storage door 22 cannot be opened.

[0062] It can be understood that by adopting this way, the container 10 with incorrect identity can be effectively prevented from being put into the storage cavity 21 of the body 20. Moreover, by adopting the way of arranging the first identity tag and the second identity tag for representing the identity of the container 10 on the body 11 and the cover 12 respectively, the identity of the container 10 can be "double-verified", compared with the way of arranging the identity tag on the body 11 or the cover 12 only, the way adopted by the present application can effectively avoid the body 11 or the cover 12 being exchanged, and further improve the safety of the container 10 in use. At the same time, since the verification operation of the identity of the container 10 is included before the storage door 22 is opened each time, and the container identity reading device can record the read identity information, once an unpredictable selling accident occurs later, the identity information recorded by the container identity reading device can be used for tracing, so as to realize traceability.

[0063] In the embodiment of the present application, the liquid obtaining mechanism 30 is used to obtain the liquid in the container 10 after the container 10 is placed into the storage cavity 21.

[0064] In combination Figures 6 to 8As shown, the liquid acquisition mechanism 30 comprises a moving plate 31, a suction component 32 and a liquid identity reading and writing device 33. The moving plate 31 is arranged above each port extending to the outside of the accommodation cavity 1201 and is configured to be able to make linear motion close to or away from each port. Each port refers to the aforementioned air exchange port 19, the liquid outlet port 110, the liquid inlet port 111 and the electromagnetic valve power port 112 provided on the cover 12. The moving plate 31 can make linear motion close to or away from each port under the driving of a moving driving device 34, which can be a conventional linear driver such as a pneumatic cylinder or an electric push rod.

[0065] Meanwhile, the moving plate 31 is provided with an air exchange docking port 35, a liquid outlet docking port 36 and a power supply docking port 37, which are respectively aligned with the air exchange port 19, the liquid outlet port 110 and the electromagnetic valve power port 112. In this way, in the liquid acquisition stage, the moving plate 31 is driven by the moving driving device 34 to approach each port on the cover 12 until the air exchange docking port 35, the liquid outlet docking port 36 and the power supply docking port 37 are respectively docked and conducted with the air exchange port 19, the liquid outlet port 110 and the electromagnetic valve power port 112. The air exchange docking port 35 is used to realize air exchange between the holding cavity 1101 and the external environment, the liquid outlet docking port 36 is used to allow the liquid in the holding cavity 1101 to flow out, and the power supply docking port 37 is used to supply power to the electrical elements such as the air exchange electromagnetic valve 16, the liquid outlet electromagnetic valve 17 and the liquid inlet electromagnetic valve 18 in the accommodation cavity 1201 through the electromagnetic valve power port 112. At this time, the input end of the suction component 32 is communicated with the liquid outlet docking port 36 through a hose, and the suction component 32 can be a pump. After the communication and conduction of each docking port and each port are completed, the liquid in the holding cavity 1101 can be pumped out through the liquid outlet docking port 36 by using the suction component 32, so as to sell the liquid in combination with the head 40 to be described below.

[0066] In the embodiment of the present application, the liquid identity reading and writing device 33 is configured to read or modify the third identity information of the third identity tag when the container 10 is located in the storage cavity 21 and the storage door 22 is closed, and the liquid identity reading and writing device 33 can compare the read third identity information with the second preset identity information. The second preset identity information is written into the liquid identity reading and writing device 33. The liquid identity reading and writing device 33 can be arranged on the moving plate 31.

[0067] When the third identity information read by the liquid identity reading and writing device 33 matches the second preset identity information, the opening and closing cover electronic lock 114 for locking the opening and closing cover 113 is unlocked, and the opening and closing cover 113 is opened to expose the air exchange socket 19, the liquid outlet socket 110, the liquid inlet socket 111, and the electromagnetic valve power supply socket 112. The opening and closing cover 113 and the cover body 12 can be hinged through a hinge shaft, and an elastic member such as a torsional spring can be arranged on the hinge shaft, so that after the opening and closing cover electronic lock 114 is unlocked, the opening and closing cover 113 can be automatically opened by the elastic member such as the torsional spring to expose the air exchange socket 19, the liquid outlet socket 110, the liquid inlet socket 111, and the electromagnetic valve power supply socket 112.

[0068] That is, when the identity of the container 10 is verified and placed in the storage cavity 21, and the storage door 22 is in a closed state, the identity of the opening and closing cover 113 on the cover body 12 needs to be verified, that is, the third identity information representing the identity of the opening and closing cover 113 is read by the liquid identity reading and writing device 33, and the third identity information is compared with the second preset identity information. The second preset identity information can be liquid manufacturer information, liquid type information, etc.

[0069] On this basis, if the third identity information matches the second preset identity information, it further indicates that the liquid in the container 10 comes from the manufacturer, at this time, the opening and closing cover electronic lock 114 is unlocked to open the opening and closing cover 113 to expose each socket on the cover body 12 blocked by the opening and closing cover 113. On the contrary, if the third identity information does not match the second preset identity information, it indicates that the liquid in the container 10 may not come from the manufacturer, at this time, the opening and closing cover electronic lock 114 is not unlocked, the opening and closing cover 113 is not opened, so that the liquid acquisition mechanism 30 cannot acquire the liquid in the container 10.

[0070] Further, the liquid identity reading and writing device 33 is also configured to read or modify the fourth identity information of the fourth identity tag when the opening and closing cover 113 is in an open state, and the liquid identity reading and writing device 33 can compare the read fourth identity information with the third preset identity information, and the third preset identity information is written into the liquid identity reading and writing device 33.

[0071] When the fourth identity information read by the liquid identity reading and writing device 33 matches the third preset identity information, the moving plate 31 performs a linear motion to approach each socket, so that the air exchange interface 35, the liquid outlet interface 36 and the power supply interface 37 on the moving plate 31 are connected and conducted with the air exchange socket 19, the liquid outlet socket 110 and the electromagnetic valve power supply socket 112 respectively. That is, after the identity of the opening and closing cover 113 is verified and the opening and closing cover 113 is opened, the identity of the disposable packaging cover 115 arranged on each socket needs to be verified, that is, the fourth identity information representing the identity of the disposable packaging cover 115 is read by the liquid identity reading and writing device 33 again, and the fourth identity information is compared with the third preset identity information. The third preset identity information can also be liquid manufacturer information, liquid type information, etc.

[0072] On this basis, if the fourth identity information matches the third preset identity information, it is further indicated that the liquid in the container 10 comes from the manufacturer, and at this time, the moving plate 31 approaches each socket on the cover body 12 under the drive of the moving drive device 34, so that the air exchange interface 35, the liquid outlet interface 36 and the power supply interface 37 on the moving plate 31 pierce the disposable packaging cover 115 on the air exchange socket 19, the liquid outlet socket 110 and the electromagnetic valve power supply socket 112 respectively, so that the air exchange interface 35, the liquid outlet interface 36 and the power supply interface 37 on the moving plate 31 are connected and conducted with the air exchange socket 19, the liquid outlet socket 110 and the electromagnetic valve power supply socket 112 on the cover body 12 respectively. At this time, the operation of placing the container 10 into the storage cavity 21 and enabling the liquid acquisition mechanism 30 to acquire the liquid is completed.

[0073] It is worth noting that through the above arrangement, after the container 10 is placed into the storage cavity 21, the storage door 22 needs to be closed first, and then the liquid identity reading and writing device 33 can verify the identity of the opening and closing cover 113, and after the identity of the opening and closing cover 113 is verified and the opening and closing cover 113 is opened, the liquid identity reading and writing device 33 will verify the identity of each socket again. It can be understood that by adopting the above-mentioned multiple verification mode, the liquid can be supplemented to the intelligent selling device without human contact, and the situation that the container 10 is temporarily replaced when the liquid acquisition mechanism 30 performs the above-mentioned operation of connecting and conducting each interface with each socket on the cover body 12 is further prevented, thereby providing reliable protection for the selling authorized liquid.

[0074] In the embodiment of the present application, the above-mentioned mode can be realized as follows: when the container 10 is located in the storage cavity 21 and the storage door 22 is closed, the liquid identity reading and writing device 33 first verifies the third identity information to unlock the opening and closing cover electronic lock 114, so as to open the opening and closing cover 113 and expose each socket, and then the liquid identity reading and writing device 33 can further verify the fourth identity information.

[0075] Specifically, in combination with the content shown in Figure 7 or Figure 8 The body 20 is further provided with a mounting cavity 24 above the storage cavity 21, and the moving plate 31 is arranged in the mounting cavity 24. An access passage 25 is arranged between the mounting cavity 24 and the storage cavity 21, and is adapted to the moving plate 31. That is, the moving plate 31 can enter the storage cavity 21 or retreat into the mounting cavity 24 from the storage cavity 21 through the access passage 25 under the driving of the moving driving device 34.

[0076] At this time, the top of the storage cavity 21 is provided with a shielding plate 26 for blocking the access passage 25, and the shielding plate 26 is used to shield the reading and writing of the third identity information and the fourth identity information by the liquid identity reading and writing device 33. The shielding plate 26 is configured to reciprocate horizontally on the top of the storage cavity 21, so that the shielding plate 26 can block or open the access passage 25.

[0077] In this way, when the storage door 22 is in the open state, the shielding plate 26 blocks the access passage 25. At this time, since the shielding plate 26 can shield the third identity information of the third identity tag, even if the container 10 is placed at the target position in the storage cavity 21, the liquid identity reading and writing device 33 on the moving plate 31 in the mounting cavity 24 cannot obtain the third identity information of the third identity tag. At this time, the opening and closing cover 113 cannot be opened, and the aforementioned docking and conduction operation cannot be realized. Correspondingly, when the storage door 22 is in the closed state, the shielding plate 26 can move from the closed position of blocking the access passage 25 to the open position of opening the access passage 25. At this time, since the access passage 25 is opened, the liquid identity reading and writing device 33 can read the third identity information of the third identity tag to verify the identity of the opening and closing cover 113. In combination with the foregoing, after the identity verification of the opening and closing cover 113 is passed, the opening and closing cover electronic lock 114 is unlocked, and the opening and closing cover 113 is opened to expose the various sockets on the cover body 12. At this time, the liquid identity reading and writing device 33 can further verify the fourth identity information of the fourth identity tag on the one-time packaging cover 115 of each socket.

[0078] Among them, in order to optimize the structure design in the storage cavity 21 and reduce the cost of moving the shielding plate 26 between the closed position of blocking the access passage 25 and the open position of opening the access passage 25, the shielding plate 26 can be moved in a linkage manner with the storage door 22.

[0079] Specifically, referring to Figure 9As shown, the shielding plate 26 can be slidingly arranged on the top of the storage cavity 21 by means of a sliding rail, so that the shielding plate 26 can slide horizontally towards or away from the storage door 22. Meanwhile, a connecting rod 27 is arranged between the shielding plate 26 and the storage door 22, one end of the connecting rod 27 is hingedly connected to the storage door 22, and the other end of the connecting rod 27 is hingedly connected to the shielding plate 26.

[0080] Thus, when the storage door 22 is in the closed state as shown in Figure 7 or Figure 8 shown, the shielding plate 26 is located away from the storage door 22 and does not block the access passage 25, at this time, the access passage 25 is in an open state. Correspondingly, in the process of the outward pivoting movement of the storage door 22 to gradually open, under the transmission action of the connecting rod 27, the pivoting movement of the storage door 22 will be converted into the horizontal linear movement of the shielding plate 26, so that the shielding plate 26 gradually approaches the access passage 25, and when the opening degree of the storage door 22 is the largest, the shielding plate 26 just moves to completely block the access passage 25, at this time, even if the container 10 is placed in the target position in the storage cavity 21, the liquid identity reading and writing device 33 cannot read the third identity information of the third identity tag. Correspondingly, when the storage door 22 is closed again, the shielding plate 26 can move reversely under the action of the connecting rod 27, so as to open the access passage 25.

[0081] In the embodiment of the present application, in order to realize the sale of liquid, the intelligent vending device capable of carrying out Internet of Things traceability on bulk liquid commodities further particularly comprises a machine head 40 arranged above the machine body 20.

[0082] In combination with the contents shown in Figure 1 , Figure 2 , Figure 10 and Figure 11 , the machine head 40 comprises a goods taking cavity 41 and a liquid outlet mechanism. Among them, one side of the goods taking cavity 41 is provided with a closable machine head cabinet door 42, the machine head cabinet door 42 is locked in the closed position by a controllable machine head cabinet door electronic lock 43, the machine head cabinet door electronic lock 43 is configured to be unlocked after the user places an order and pays through the man-machine interaction display screen 50, and the man-machine interaction display screen 50 is configured for the user to carry out man-machine interaction. For example, the man-machine interaction display screen 50 can be arranged at a proper position on the outer wall of the machine head 40, when the user needs to purchase liquid, the user can directly place an order through the man-machine interaction display screen 50, and when the user places an order and pays, the machine head cabinet door electronic lock 43 can be automatically unlocked, so that the machine head cabinet door 42 is opened.

[0083] On this basis, considering that the liquid outlet of the common liquid vending machine for outputting liquid is always exposed to the external environment in normal state, such a way is not conducive to selling liquid such as liquor, because the liquid outlet is easy to be contaminated by long-term exposure to the external environment, so that the liquid output by the liquid outlet is contaminated, and if the liquid outlet is long-term exposed to the external environment, the risk of illegal persons putting harmful substances into the liquid outlet is increased.

[0084] Therefore, the embodiment of the present application further improves the structure of the machine head 40. Specifically, continuing to refer to Figure 10 and Figure 11 , the liquid outlet mechanism includes a protection cavity 44, a liquid outlet nozzle 45, a liquid outlet nozzle sealing device, and a three-way electromagnetic valve 46. Among them, the protection cavity 44 can be arranged above the take-out cavity 41, and the protection cavity 44 is provided with a liquid outlet nozzle passage 47 communicating with the take-out cavity 41, the liquid outlet nozzle 45 is arranged in the protection cavity 44, and the liquid outlet nozzle 45 is configured to be able to enter or exit the take-out cavity 41 through the liquid outlet nozzle passage 47. Among them, the liquid outlet nozzle 45 can enter or exit the take-out cavity 41 under the drive of the liquid outlet nozzle drive device 48, and the liquid outlet nozzle drive device 48 can be a conventional linear drive such as a pneumatic cylinder, an electric push rod, etc.

[0085] The liquid outlet nozzle sealing device is used to selectively open or close the liquid outlet nozzle passage 47. Further, the liquid outlet nozzle sealing device can include a sealing plate 49 and a sealing plate drive device 410, wherein the sealing plate 49 can reciprocate along the horizontal direction to approach or away from the liquid outlet nozzle passage 47 under the drive of the sealing plate drive device 410, and the sealing plate drive device 410 can be a conventional linear drive such as a pneumatic cylinder, an electric push rod, etc.

[0086] The three-way electromagnetic valve 46 is used to control the opening and closing of the liquid outlet nozzle 45. Specifically, the first end of the three-way electromagnetic valve 46 is connected to the liquid outlet nozzle 45, the second end of the three-way electromagnetic valve 46 is connected to the output end of the aforementioned suction component 32 through a hose, and the third end of the three-way electromagnetic valve 46 is connected with an air pipe 411, so as to maintain the air pressure in the three-way electromagnetic valve 46 within a reasonable range,

[0087] Based on the above setting, when the user needs to buy liquid, first, the user can place an order by means of the man-machine interaction display screen 50, and after the user places an order successfully and pays, the electronic lock 43 of the nose cabinet door is unlocked to open the nose cabinet door 42; then, the sealing plate driving device 410 of the liquid outlet nozzle sealing device drives the sealing plate 49 away from the liquid outlet nozzle channel 47, the liquid outlet nozzle channel 47 is opened, and the liquid outlet nozzle driving device 48 drives the liquid outlet nozzle 45 to enter the take-out cavity 41 from the protection cavity 44 through the liquid outlet nozzle channel 47. After the liquid outlet nozzle 45 enters the take-out cavity 41, the suction component 32 of the liquid acquisition mechanism 30 is started, and the liquid outlet electromagnetic valve 17 is opened to suck out the liquid in the holding cavity 1101 through the suction component 32. The liquid flows out through the liquid outlet nozzle 45 after flowing through the liquid outlet interface 14, the liquid outlet electromagnetic valve 17, the liquid outlet socket 110, the liquid outlet docking interface 36, the suction component 32 and the three-way electromagnetic valve 46 in turn. At this time, the user can obtain the liquid flowing out from the liquid outlet nozzle 45.

[0088] After a single sale is completed, the suction component 32 stops, the liquid outlet electromagnetic valve 17 and the three-way electromagnetic valve 46 are closed, the liquid outlet nozzle 45 is driven by the liquid outlet nozzle driving device 48 to retreat to the protection cavity 44, and the sealing plate driving device 410 drives the sealing plate 49 to close the liquid outlet nozzle channel 47, and the nose cabinet door 42 is closed by the user.

[0089] It can be understood that through the above setting, the liquid outlet nozzle 45 can be reliably protected when liquid is not sold, thereby reducing the risk of the liquid outlet nozzle 45 being contaminated for a long time exposed to the external environment, and reducing the risk of illegal substances being put into the liquid outlet nozzle 45 by illegal elements.

[0090] Further, in combination with the content shown in Figure 6 The flow monitoring component 38, such as a flow meter, can be provided on the pipeline between the suction component 32 and the three-way electromagnetic valve 46, so as to detect the amount of liquid sucked out through the suction component 32 in real time.

[0091] Further, the nose 40 can also be provided with a security mechanism. The security mechanism can include a camera provided on the nose 40 and fire-fighting facilities and the like stored in the nose 40. The camera is used to monitor the use of the intelligent vending device in real time, and the fire-fighting facilities are used in an emergency.

[0092] It should be noted that although the application only describes a single container 10 matched with a single head 40 in the above embodiments to sell a single kind of liquid, the smart vending device capable of tracing bulk liquid goods through the Internet of Things disclosed in the embodiments of the application is not limited thereto. For example, in actual implementation, a single smart vending device can be equipped with multiple containers 10 to store different kinds, tastes or qualities of liquid by using multiple containers 10, and the multiple containers 10 can be matched with one head 40 to sell multiple different kinds, tastes or qualities of liquid stored in the multiple containers 10 by using one head 40. Of course, in the case of multiple containers 10, the head 40 can also be matched with the containers 10 one by one to sell the liquid in a single container 10 by using a single head 40. In this case, a single smart vending device can also sell multiple different kinds, tastes or qualities of liquid.

[0093] The above only describes the preferred embodiments of the application and is not intended to limit the application. The application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
