[0033] like Figure 1-3 Shown is an integrated weighing and settlement device 100 of the present application, comprising: a weighing device 10 , an identification device 20 and a locking mechanism 30 .

[0034] The weighing device 10 has a weighing function, and the weight of the object can be measured when an object is placed on the upper surface of the weighing device 10. In the present application, a first receiving slot 11 is formed on one side of the weighing device 10.

[0035] The identification device 20 has a tag information reading function and can identify the information of different tags. In the present application, the identification device 20 is at least partially disposed in the first receiving slot 11 of the weighing device 10, and the identification device 20 can be detachably inserted into the weighing device 10. Preferably, the identification device 20 is completely accommodated in the first receiving slot 11 of the weighing device 10.

[0036] The locking mechanism 30 is disposed between the weighing device 10 and the identification device 20 to lock the identification device 20 into the first receiving slot 11. In this way, when the integrated weighing and settlement device 100 is in the working state, the identification device 20 is taken out of the weighing device 10 for identification operation. When the integrated weighing and settlement device 100 is in the non-working state, the identification device 20 is inserted back into the weighing device 10, thereby reducing the space occupied by the device.

[0037] Specifically, the identification device 20 is provided with a tag identification module, a first battery and a first wireless transmission module. The tag identification module is used to provide a tag identification function. The first battery is connected to the tag identification module and the first wireless transmission module to provide power for the tag identification module and the first wireless transmission module. Preferably, the identification device 20 is also provided with a coupling antenna, which is connected to the tag identification module, so as to realize the tag identification function beyond the identification range of the tag identification module within a specific range.

[0038] The weighing device 10 is provided with a processor and a second wireless transmission module. The weighing device 10 is connected to an external power source via a power cord to operate. The first wireless transmission module is wirelessly connected to the second wireless transmission module for data exchange. Specifically, after identifying the tag information, the identification device 20 sends the identified information to the second wireless transmission module via the first wireless transmission module.

[0039] As a preferred implementation, the locking mechanism 30 includes: a locking slot 31 , a locking rod 32 and a torsion spring 33 .

[0040] Among them, the locking groove 31 is arranged on the identification device 20. Specifically, it is arranged on the side of the identification device 20. The locking rod 32 cooperates with the locking groove 31 to lock the identification device 20 in the first receiving groove 11. The locking rod 32 is rotatably arranged in the weighing device 10 through the rotating shaft, and the locking rod 32 can rotate between the locking position and the unlocking position. The torsion spring 33 is arranged between the locking rod 32 and the rotating shaft to force the locking rod 32 to remain in the locking position. A locking protrusion 321 is provided at one end of the locking rod 32, and a pressing portion 322 is provided at the other end. The middle part of the locking rod 32 is rotatably connected to the rotating shaft, the locking protrusion 321 extends into the first receiving groove 11 and cooperates with the locking groove 31, and the pressing portion 322 at least partially extends out of the housing of the weighing device 10 for user operation. When the pressing portion 322 receives external pressing force, the locking rod 32 overcomes the elastic force of the torsion spring 33 and rotates from the locking position to the unlocking position to release the lock of the identification device 20.

[0041] It is understandable that, in the process of inserting the identification device 20 into the first receiving slot 11, the identification device 20 first overcomes the elastic force of the torsion spring 33, so that the locking rod 32 is rotated from the locked position to the unlocked position. When the identification device 20 is fully inserted into the first receiving slot 11, the locking protrusion 321 of the locking rod 32 is engaged with the locking slot 31 of the identification device 20, and returns to the locked position. When the identification device 20 needs to be removed, it is only necessary to press the pressing portion 322 of the locking rod 32 to rotate the locking rod 32 to the unlocked position.

[0042] Preferably, in the present application, the integrated weighing and settlement device 100 includes two locking mechanisms 30 , and the two locking mechanisms 30 are respectively arranged on both sides of the identification device 20 .

[0043] As a preferred embodiment, the locking mechanism 30 further includes a release spring 34 .

[0044] The release spring 34 is disposed between the weighing device 10 and the identification device 20. When the identification device 20 is installed in the weighing device 10, the release spring 34 applies an elastic force to the identification device 20 to eject it from the first receiving groove 11. In this way, when the pressing portion 322 of the locking rod 32 is pressed, the release spring 34 can directly eject the identification device 20, thereby improving the convenience of disassembly of the identification device 20.

[0045] As a preferred embodiment, a charging circuit module is provided in the weighing device 10, and the identification device 20 is electrically connected to the weighing device 10 after being installed in the first receiving slot 11, and the charging circuit module is electrically connected to the first battery. When the weighing device 10 is connected to an external power source through a power cord, the charging circuit module charges the first battery through the external power source. A first electrical connection interface 12 is provided in the first receiving slot 11 of the weighing device 10, and a second electrical connection interface 21 that cooperates with the first electrical connection interface 12 is provided on the identification device 20. When the identification device 20 is installed in the first receiving slot 11, the first electrical connection interface 12 is connected to the second electrical connection interface 21.

[0046] As a preferred embodiment, a second battery is provided in the weighing device 10, and the charging circuit module is electrically connected to the first battery. When the weighing device 10 is connected to an external power supply via a power cord, the charging circuit module charges the first battery via the external power supply. When the power cord is not connected to the external power supply, the charging circuit module charges the first battery via the second battery.

[0047] It is understandable that when the weighing device 10 is not connected to the power line, the charging circuit module can determine whether to charge the first battery through the second battery according to the capacity relationship between the second battery and the first battery. Specifically, in the present application, the charging circuit module charges the first battery through the second battery only when the remaining percentage of the power of the second battery is less than the remaining percentage of the power of the first battery. In this way, the remaining use time of the identification device 20 and the weighing device 10 is ensured to be the same as much as possible.

[0048] In the present application, the first battery is detachably connected to the identification device 20 , and the second battery is detachably connected to the weighing device 10 .

[0049] As a preferred implementation, the identification device 20 of the present application is further provided with a low-battery warning module for performing a warning operation when the battery level of the first battery of the identification device 20 is low.

[0050] As a preferred embodiment, a second receiving slot 13 is provided on the other side of the weighing device 10 opposite to the side provided with the first receiving slot 11. The weighing device 10 further includes an image acquisition component 14, which is disposed in the second receiving slot 13 and can be moved between a non-working position and a working position. Preferably, the image acquisition component 14 is completely accommodated in the second receiving slot 13 of the weighing device 10. Specifically, the image acquisition component 14 includes a camera 141 and an adjustment hose 142. The camera 141 is connected to one end of the adjustment hose 142, and the other end of the adjustment hose 142 is connected to the second receiving slot 13. When the image acquisition component 14 is in the non-working position, the adjustment hose 142 and the camera 141 are at least partially located in the second receiving slot 13.

[0051] In the non-working state, the camera 141 and the adjusting hose 142 are retracted into the second receiving slot 13 of the weighing device 10 by setting the bending state of the adjusting hose 142. In the working state, the camera 141 can be adjusted to a plurality of working positions by setting the bending state of the adjusting hose 142 according to actual needs, so as to take pictures of the weighed object on the weighing device 10.

[0052] Specifically, after the tag identification module identifies the tag information in the item, it sends the tag information to the second wireless transmission module through the first wireless transmission module, weighs the weight of the item through the weighing device 10, obtains the image information of the item through the camera 141, and the processor calculates the price of the item based on the received tag information and the weighed weight, and sends the calculated price and the image information corresponding to the item to the settlement system.

[0053] As an optional implementation, an image analysis module and an automatic warning module are also provided in the weighing device 10. The image analysis module processes and analyzes the image information collected by the camera 141 to determine the type of the object, and compares the determination result with the type information of the object contained in the tag information received by the second wireless transmission module to determine whether the two are the same. When the two are different, the automatic warning module performs a warning operation.

[0054] Taking a plate of dishes as an example, through the label on the plate, the label recognition module identifies the type of dish corresponding to the plate, including dish information and price, etc. When weighing, the image analysis module can determine whether the type of dish is the same as the type of dish recognized by the label recognition module based on the image information of the dish acquired by the camera 141. If the recognition result is the same, the pricing and settlement will continue. If the recognition result is different, the automatic warning module will perform a warning operation, such as issuing a warning sound.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
