[0029] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope of the present application.

For example, some operations / steps can be further decomposed, combined or partially merged, so the actual execution order can be changed according to actual conditions.

[0031] It should be understood that the terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and the appended claims of the present application, unless otherwise clear from the context, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0032] It should also be understood that the term "and / or" used in the specification and the appended claims of the present application means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0033] At present, the quantitative discharge of materials mainly relies on the timer function of the discharge device, that is, by setting the discharge time of the discharge device, the discharge device is automatically turned off when the discharge time is reached. In order to improve the accuracy of material discharge, related technologies introduce a weighing device to control whether the discharge device performs a discharge operation to achieve quantitative discharge of materials. However, the existing weighing device has a low degree of intelligence, generally only has the function of detecting the weight of the material contained in the material container, and cannot realize intelligent interaction with the discharge device according to specific application scenarios (ordinary weighing scenarios and discharge weighing scenarios), thereby causing the user to need to manually switch the working mode of the weighing device, making the discharge operation cumbersome and greatly reducing the discharge efficiency.

[0034] Embodiments of the present application provide a screen operation device, a weighing device, a discharge device and a discharge control system. The discharge device is used to produce materials, the weighing device is used to detect the weight of the materials produced by the discharge device, and can accurately switch its working mode by detecting its connection state with the discharge device, without the user manually switching the working mode of the weighing device, thereby realizing intelligent interaction between the weighing device and the discharge device, reducing the steps of the user performing the discharge operation, and thereby improving the discharge efficiency.

[0035] For example, the weighing device can be an electronic scale; the discharging device can include a powder discharging device and a liquid discharging device; the discharging device can include a grinding device, which can be various types of bean grinders, such as coffee bean grinders, soybean grinders, flour grinders, etc.; and the liquid discharging device can be various types of coffee machines and tea making machines, etc.

[0036] The specific structure and working principle of the weighing device and the discharging device will be described in detail below.

[0037] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a discharging control system 100 provided by an embodiment of the present application.

[0038] As shown in Figure 1 , the discharging control system 100 can include a weighing device 200 and a discharging device 300. The weighing device 200 can be connected to the discharging device 300 through a connection line, for example, the weighing device 200 can be connected to the discharging device 300 through wired connection, screen operation device 400 and control screen 34 interaction, etc.

[0039] As shown in Figure 1 , the weighing device 200 can be placed on the discharging device 300. When the discharging device 300 is provided with a weighing table, the weighing table serves as a weighing area 211, and the weighing device 200 can be placed on the weighing table; when the discharging device 300 is not provided with a weighing table, the weighing device 200 can be placed below the discharging port of the discharging device 300.

[0040] The specific structure and working principle of the weighing device 200 provided by the present application will be described in detail below. Figures 1 to 3

[0041] Please refer to Figure 2 and Figure 3 , Figure 2 is a structural schematic diagram of a weighing device 200 provided by an embodiment of the present application, Figure 3 is a hardware schematic diagram of a weighing device 200 provided by an embodiment of the present application. As Figure 2 and Figure 3 ​As shown, the weighing device 200 may include a first body 21, a weighing module 22, and a first control module 23. The first body 21 includes a weighing area 211 for placing a material container. The material container is generally positioned corresponding to the discharge port of the discharging device 300, ensuring that the material container can hold the material generated by the discharging device 300 and that the generated material does not spill outside the material container. The discharging device 300 includes a control screen 34, which displays a control interface for controlling the discharging device 300. The weighing module 22 is located within the first body 21 and is used to weigh the material in the material container located in the weighing area 211. The first control module 23 is located within the first body 21 and is electrically connected to the weighing module 22.

[0042] The weighing module 22 and the first control module 23 can be connected via a communication bus, which can be any applicable communication bus such as an integrated circuit (I2C) bus.

[0043] For example, the first control module 23 may include a memory and a processor. The memory may store an operating system and computer programs. The processor provides computing and control capabilities to support the operation of the entire weighing device 200. The processor may be a Central Processing Unit (CPU), or it may be a general-purpose processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor, or it may be any conventional processor.

[0044] like Figure 1 As shown, the first body 21 is also provided with a first connection port 210, which is used to connect to the screen operation device 400. The screen operation device 400 is detachably installed on the first body 21 and at least partially contacts the control screen 34. The screen operation device 400 can operate the control interface of the control screen 34 to control the discharging device 300, so that the discharging device 300 can perform the corresponding discharging operation according to the operation of the screen operation device 400 on the control screen 34. When the first control module 23 detects that the screen operation device 400 is connected to the first connection port 210, it can switch the working mode of the weighing device 200 to the quantitative control mode.

[0045] The screen operating device 400 is a device that can contact the control screen 34 and operate the control interface of the control screen 34 to control the discharging device 300 by means of a relay or a capacitive pen or the like.

[0046] Specifically, the working mode of the weighing device 200 can include a normal weighing mode and a quantitative control mode. Since the weighing device 200 generally includes two application scenarios (a normal weighing scenario and a discharging weighing scenario), the normal weighing scenario refers to that the user only uses the weighing device 200 for weight detection, and then the user uses the weighed material to perform corresponding operations, for example, when the user needs to manually grind coffee beans, at this time, the weighing device 200 is only used for weighing, so the working mode of the weighing device 200 at this time is the normal weighing mode. The discharging weighing scenario refers to that the weighing device 200 detects the weight of the material generated by the discharging device 300 and controls the operation of the discharging device 300 based on the weight of the material. At this time, the weighing device 200 is not only used for weighing, but also used for controlling the discharging device 300, so the working mode of the weighing device 200 at this time is the quantitative control mode.

[0047] For example, the screen operating device 400 can be connected to the first connecting port 210 through a connecting line to achieve that the screen operating device 400 is detachably installed on the first body 21, and the screen operating device 400 can be fixedly installed on the discharging device 300 to make the screen operating device 400 at least partially contact the control screen 34, so that the screen operating device 400 can operate the control interface of the control screen 34.

[0048] For example, when the first control module 23 detects that the first connecting port 210 is connected to the connecting line and detects that the other end of the connecting line is the screen operating device 400, at this time, the first control module 23 switches the working mode of the weighing device 200 from the normal weighing mode to the quantitative control mode.

[0049] The weighing device 200 provided by the embodiment of the present application can accurately switch the working mode of the weighing device 200 by detecting the connection state of the first connecting port 210 and the screen operating device 400, without the user manually switching the working mode of the weighing device 200, thereby realizing the intelligent interaction between the weighing device 200 and the discharging device 300, reducing the steps of the user performing the discharging operation, and thereby improving the discharging efficiency. At the same time, the weighing device 200 can interact with the control screen 34 of the discharging device 300 through the screen operating device 400, without the user manually controlling, and can more accurately and quickly control the discharging device 300, thereby improving the discharging accuracy.

[0050] In some embodiments, the first control module 23 is further configured to switch the working mode of the weighing device 200 to the normal weighing mode when it is detected that the first connection port 210 is disconnected from the screen operation device 400. The weighing device 200 of the present application can accurately switch the working mode of the weighing device 200 by detecting the connection state of the first connection port 210 and the screen operation device 400, without the need for the user to manually switch the working mode of the weighing device 200, so that the weighing device 200 can meet the user's usage requirements in any scenario.

[0051] For example, if the first control module 23 detects that the working mode of the weighing device 200 is the quantitative control mode, when the first control module 23 detects that the connection line connected to the first connection port 210 is disconnected, the first control module 23 can switch the working mode of the weighing device 200 from the quantitative control mode to the normal weighing mode.

[0052] In some embodiments, the first body 21 further comprises an operation area 212, the operation area 212 comprising a display interface and / or a weight setting button, the display interface being configured to display the mode identifier corresponding to the current working mode and the measurement data corresponding to the current working mode; the first control module 23 is configured to display the set discharge weight value, the actual discharge weight value and the weight unit on the display interface when the working mode of the weighing device 200 is the quantitative control mode. The first control module 23 is configured to display the timing duration, the weight value and the weight unit on the display interface when the working mode of the weighing device 200 is the normal weighing mode. The weighing device 200 of the present application can display the current working mode and the corresponding measurement data on the display interface, so that the user can clearly view the current working mode and the corresponding measurement data of the weighing device 200.

[0053] For example, if the working mode of the weighing device 200 is the quantitative control mode at this time, the user can set the corresponding set discharge weight value through the weight setting button, and after setting the set discharge weight value, the weighing device 200 controls the discharge device 300 to perform the corresponding discharge operation. Therefore, the display interface will display the mode identifier corresponding to the quantitative control mode and the set discharge weight value, the actual discharge weight value and the weight unit.

[0054] For example, if the working mode of the weighing device 200 is the normal weighing mode at this time, the user can weigh the material on the weighing device 200, and set the discharge duration of the discharge device 300, and the discharge device 300 will automatically stop when the discharge duration is reached. Therefore, the display interface will display the mode identifier corresponding to the normal weighing mode and the timing duration, the weight value and the weight unit.

[0055] As Figure 1As shown, in some embodiments, the first connecting port 210 is also connected with the second connecting port 310 of the discharging device 300 through a connecting line; and the first control module 23 is further configured to switch the working mode of the weighing device 200 to the quantitative control mode when it is detected that the first connecting port 210 is connected with the second connecting port 310 through the connecting line. Thus, when the screen operation device 400 cannot work, the working mode of the weighing device 200 can also be accurately switched by detecting the connection state of the first connecting port 210 and the second connecting port 310, without the need for the user to manually switch the working mode of the weighing device 200, so as to realize the intelligent interaction between the weighing device 200 and the discharging device 300, reduce the steps of the user in performing the discharging operation, and thus improve the discharging efficiency.

[0056] In some embodiments, the first control module 23 controls the discharging device 300 to charge the weighing device 200 when it is detected that the first connecting port 210 is connected with the second connecting port 310 and the discharging device 300 is connected with the power supply. Thus, the weighing device 200 can be charged when the discharging device 300 is connected with the power supply, so that the weighing module 22 can be charged by the discharging device 300 while controlling the discharging device 300, thereby avoiding the power-off of the weighing module 22 during the control of the discharging device 300, so as to affect the working of the discharging device 300.

[0057] In some embodiments, the discharging device 300 charges the weighing device 200 when it is detected that the first connecting port 210 is connected with the second connecting port 310 and the discharging device 300 is connected with the power supply. Thus, the weighing device 200 can be charged when the discharging device 300 is connected with the power supply, so that the weighing module 22 can be charged by the discharging device 300 while controlling the discharging device 300, thereby avoiding the power-off of the weighing module 22 during the control of the discharging device 300, so as to affect the working of the discharging device 300.

[0058] For example, the first control module 23 controls the discharging device 300 to charge the weighing device 200 when it is detected that the first connecting port 210 is connected with the second connecting port 310 and the discharging device 300 is connected with the power supply. Thus, the weighing device 200 can be charged through the discharging device 300 when the discharging device 300 is connected with the power supply, so that the weighing module 22 can be charged by the discharging device 300 while controlling the discharging device 300, thereby avoiding the power-off of the weighing module 22 during the control of the discharging device 300, so as to affect the working of the discharging device 300.

[0059] As Figure 4 and Figure 5As shown, in some embodiments, the screen operation device 400 includes a protective housing 41, a control module 42, an antenna module 43, and a touch control 44. The control module 42 is disposed within the protective housing 41 and is used to receive the powder dispensing control signal sent by the weighing device 200. The antenna module 43 is disposed within the protective housing 41 and connected to the control module 42, and is used to generate a touch signal based on the powder dispensing control signal. The touch control 44 is disposed at one end of the protective housing 41 near the control screen 34 and is connected to the antenna module 43. The touch control 44 is used to operate the control interface of the control screen 34 based on the touch signal. Thus, through signal transmission between the weighing device 200, the control module 42, and the antenna module 43, the touch control 44 can be triggered to operate the control interface of the control screen 34 without the user touching the screen operation device 400.

[0060] The powder discharge control signal can be used to control whether the discharge device 300 performs a discharge operation, and can also be used to control the discharge parameters of the discharge device 300, etc., without specific limitations here. The touch signal can be used to control the touch control 44 to touch the control screen 34, so that the discharge device 300 performs the discharge operation corresponding to the powder discharge control signal.

[0061] Specifically, the control module 42 is housed within the protective housing 41 and can be connected to the first connection port 210 via a connecting cable, receiving the powder dispensing control signal sent by the weighing device 200. The antenna module 43 is housed within the protective housing 41 and can be fixedly connected to the control module 42 by welding. The antenna module 43 generates touch signals based on the powder dispensing control signal. The touch control 44 is located at the end of the protective housing 41 near the control screen 34 and is connected to the antenna module 43. The touch control 44 operates the control interface of the control screen 34 based on the touch signal.

[0062] It should be noted that the product size of the screen operating device 400 can be any size, such as 42.5cm*24.8cm*16.6cm. The product size provided in this application can be applied to the smaller size control screen 34 and can be more easily fixed on the control screen 34.

[0063] like Figure 6 As shown, in some embodiments, the screen operating device 400 further includes a fixing member 45, which is fixedly disposed on the surface of the control screen 34 and is limited and fixedly engaged with the protective housing 41 to allow the touch control 44 to contact the control interface. This allows the screen operating device 400 to be fixed at a specific position on the control screen 34, enabling the touch control 44 to contact the control interface and thus accurately control the discharging device 300 to perform the corresponding discharging operation.

[0064] Exemplarily, the fixing member 45 can be fixed on the surface of the control screen 34 by means of double-sided adhesive tape, and the fixing member 45 can be fixed in position with the protective shell 41 to enable the touch control 44 to contact the control interface. In this way, the screen operation device 400 can be fixed in a specific position of the control screen 34 so that the touch control 44 can contact the control interface to accurately control the discharging device 300 to perform corresponding discharging operations.

[0065] In some embodiments, the touch control 44 comprises a touch pen head 440, and a pen tip portion 441 of the touch pen head 440 contacts a first interaction area of the control interface, which is used to represent an area in which the screen operation device 400 performs screen operations on the control interface.

[0066] In some embodiments, the touch control 44 comprises a touch pen head 440, and a pen tip portion 441 of the touch pen head 440 contacts a first interaction area of the control interface, which is used to represent an area in which the screen operation device 400 performs screen operations on the control interface.

[0067] Exemplarily, the pen tip portion 441 of the touch pen head 440 can contact the first interaction area of the control interface and perform touch control in the first interaction area to control the discharging device 300 to perform discharging operations set in the first interaction area; and the user can also perform touch control in a second interaction area of the control interface by contacting the control screen 34 to control the discharging device 300 to perform discharging operations set in the second interaction area.

[0068] In some embodiments, the fixing member 45 comprises a fixing portion 451 and a supporting portion 450, the fixing portion 451 is fixed on the surface of the control screen 34, the supporting portion 450 is used to support the screen operation device 400, and the fixing portion 451 and the supporting portion 450 are arranged at a preset angle to enable the screen operation device 400 to be arranged at a preset angle with the control screen 34. In this way, by designing the angle between the screen operation device 400 and the control screen 34, the contact area between the touch control 44 and the control screen 34 can be increased, the touch control accuracy of the touch control 44 can be improved, and the touch control 44 can be prevented from failing to contact to control the discharging device 300.

[0069] In some embodiments, the fixing member 45 comprises a fixing portion 451 and a supporting portion 450, the fixing portion 451 is fixed on the surface of the control screen 34, the supporting portion 450 is used to support the screen operation device 400, and the fixing portion 451 and the supporting portion 450 are arranged at a preset angle to enable the screen operation device 400 to be arranged at a preset angle with the control screen 34. In this way, by designing the angle between the screen operation device 400 and the control screen 34, the contact area between the touch control 44 and the control screen 34 can be increased, the touch control accuracy of the touch control 44 can be improved, and the touch control 44 can be prevented from failing to contact to control the discharging device 300.

[0070] Exemplarily, the fixing portion 451 and the supporting portion 450 can be arranged at an angle of 45°, and since the screen operation device 400 is arranged on the supporting portion 450, the pen tip portion 441 of the touch pen head 440 is also arranged at an angle of 45° with the control screen 34.

[0071] In some embodiments, the metal material and the plastic material are injection molded by using an insert injection molding process to form the touch control 44 on the surface of the protective shell 41.

[0072] For example, the touch control 44 can be a metal / plastic integrated part formed by insert injection molding process, which can have a better shielding effect on the antenna signal, making the powder discharge control signal transmission more stable, and enabling the weighing device 200 to stably control the discharge device 300.

[0073] The following will combine Figures 1 to 3 This application provides a detailed description of the specific structure and working principle of another weighing device 200 provided in this application.

[0074] like Figures 1-3 As shown, the weighing device 200 may include a first body 21, a weighing module 22, and a first control module 23. The first body 21 includes a weighing area 211 for placing a material container. The material container is generally positioned corresponding to the discharge port of the discharging device 300, ensuring that the material container can hold the material generated by the discharging device 300 and that the generated material does not spill outside the material container. The discharging device 300 includes a control screen 34, which displays a control interface for controlling the discharging device 300. The weighing module 22 is located within the first body 21 and is used to weigh the material in the material container located in the weighing area 211. The first control module 23 is located within the first body 21 and is electrically connected to the weighing module 22.

[0075] The first body 21 is also provided with a first connection port 210, which can be connected to the discharge device 300 through a connection line; when the first control module 23 detects that the first connection port 210 is connected to the discharge device 300 through the connection line, it switches the working mode of the weighing device 200 to the quantitative control mode.

[0076] For example, the first connection port 210 can be connected to the discharge device 300 via a connecting cable in the following ways: the first connection port 210 can be connected to the screen operation device 400 via the connecting cable. The screen operation device 400 is detachably mounted on the first body 21 and at least partially contacts the control screen 34, thereby enabling the screen operation device 400 to operate the control interface of the control screen 34 to control the discharge device 300. At this time, when the first control module 23 detects that the first connection port 210 is connected to the screen operation device 400 via the connecting cable, it switches the working mode of the weighing device 200 to the quantitative control mode.

[0077] For example, the first connecting port 210 can also be connected to the second connecting port 310 of the discharging device 300 through the connecting line, so that the weighing device 200 can send the powder discharging control signal to the discharging device 300 through the first connecting port 210 and the second connecting port 310 to control the discharging device 300. At this time, the first control module 23 switches the working mode of the weighing device 200 to the quantitative control mode when detecting that the first connecting port 210 is connected to the second connecting port 310 through the connecting line.

[0078] It should be noted that the specific embodiments of the two connection modes of the weighing device 200 and the discharging device 300 mentioned above have been described in detail in the foregoing, and can be referred to the above embodiments, and will not be described in detail here.

[0079] The weighing device 200 provided by the embodiment of the present application can accurately switch the working mode of the weighing device 200 by detecting the connection state of the first connecting port 210 and the discharging device 300, without the need for the user to manually switch the working mode of the weighing device 200, thereby realizing the intelligent interaction between the weighing device 200 and the discharging device 300, reducing the steps of the user to perform the discharging operation, and thereby improving the discharging efficiency. At the same time, the weighing device 200 not only can interact with the control screen 34 of the discharging device 300 through the screen operation device 400, without the need for the user to manually control, but also can more accurately and quickly control the discharging device 300, thereby improving the discharging accuracy; when the screen operation device 400 cannot work, the weighing device 200 can also accurately switch the working mode of the weighing device 200 by detecting the connection state of the first connecting port 210 and the second connecting port 310, without the need for the user to manually switch the working mode of the weighing device 200, thereby realizing the intelligent interaction between the weighing device 200 and the discharging device 300, reducing the steps of the user to perform the discharging operation, and thereby improving the discharging efficiency.

[0080] For example, the first connecting port 210 can also be connected to the second connecting port 310 of the discharging device 300 through the connecting line, so that the weighing device 200 can send the powder discharging control signal to the discharging device 300 through the first connecting port 210 and the second connecting port 310 to control the discharging device 300. At this time, the first control module 23 switches the working mode of the weighing device 200 to the quantitative control mode when detecting that the first connecting port 210 is connected to the second connecting port 310 through the connecting line. Figure 1 , Figure 7 and Figure 8As shown, the discharging device 300 can place the weighing device 200, and the discharging device 300 comprises a second body 31, a control screen 34, a second control module 33 and a discharging module 32. The second body 31 comprises a carrying area 311 for placing the weighing device 200, and the weighing device 200 comprises a first connecting port 210 for connecting with a screen operating device 400, the screen operating device 400 at least partially contacts with the control screen 34, and the screen operating device 400 can operate the control interface of the control screen 34 according to the discharging control signal sent by the weighing device 200; the control screen 34 displays a control interface for controlling the discharging device 300. The second control module 33 is arranged in the second body 31 and is used for generating a discharging control signal; the discharging module 32 is arranged in the second body 31 and is electrically connected with the second control module 33, and the discharging module 32 is used for discharging. The second control module 33 is also used for generating a first discharging control signal according to the operation signal of the screen operating device 400 on the control interface, so that the discharging module 32 performs corresponding discharging operation according to the first discharging control signal.

[0081] The first discharging control signal is a discharging control signal generated in response to the operation of the screen operating device 400 on the control screen 34, i.e. a discharging control signal generated in response to the touch operation in the first interaction area. The second control module 33 can also generate a second discharging control signal, and the second discharging control signal is a discharging control signal generated in response to the operation of the user on the control screen 34, i.e. a discharging control signal generated in response to the touch operation in the first interaction area.

[0082] As shown, Figure 8 The second control module 33 and the discharging module 32 can be connected through a communication bus, which can be an integrated circuit (Inter□integrated Circuit, I2C) bus or any applicable communication bus.

[0083] The second control module 33 can include a memory and a processor. The memory can store an operating system and a computer program. The processor can provide computing and control capabilities to support the operation of the entire weighing device 200. The processor can be a central processing unit (CPU), and can also be a general-purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, or the like. The general-purpose processor can be a microprocessor, or can also be any conventional processor or the like.

[0084] When the working mode of the weighing device 200 is switched to the quantitative control mode, the weighing device 200 can send a powder discharging control signal to the screen operation device 400 through the first connection port 210. The screen operation device 400 generates a corresponding touch signal according to the powder discharging control signal, so that the screen operation device 400 generates an operation signal on the control interface. The second control module 33 generates a first discharging control signal according to the operation signal of the screen operation device 400 on the control interface, so that the discharging module 32 performs corresponding discharging operation according to the first discharging control signal.

[0085] When the working mode of the weighing device 200 is switched to the ordinary weighing mode, the second control module 33 generates a second discharging control signal according to the operation signal of the user on the control interface, so that the discharging module 32 performs corresponding discharging operation according to the second discharging control signal.

[0086] The discharging device 300 provided by the embodiment of the present application can interact with the weighing device 200 through the screen operation device 400, so as to realize intelligent powder discharging control of the weighing device 200 on the discharging device 300. The user can realize quantitative discharging of the discharging device 300 without operating the control screen 34, and can greatly reduce the number of times of touching the control screen 34, so as to avoid problems such as poor contact of the control screen 34 caused by long-time touching of the control screen 34. The embodiment of the present application realizes intelligent interaction between the weighing device 200 and the discharging device 300, and can more accurately and quickly control the discharging device 300, so as to improve the discharging precision, reduce the steps of the user in performing the discharging operation, and improve the discharging efficiency.

[0087] In some embodiments, the second body 31 further comprises a second connecting port 310 connected with the first connecting port 210 through a connecting line, so that the first control module 23 of the weighing device 200 switches the working mode of the weighing device 200 to the quantitative control mode when detecting that the first connecting port 210 is in communication with the second connecting port 310. Thus, when the screen operation device 400 cannot work, the working mode of the weighing device 200 can also be accurately switched by detecting the connection state of the first connecting port 210 and the second connecting port 310, without the need for the user to manually switch the working mode of the weighing device 200, thereby realizing the intelligent interaction between the weighing device 200 and the discharging device 300, reducing the steps of the user performing the discharging operation, and thereby improving the discharging efficiency.

[0088] For example, when the first control module 23 detects that the first connecting port 210 is connected to the second connecting port 310 through the connecting line, it can be determined that the weighing device 200 is connected with the discharging device 300 and the weighing device 200 can control the discharging device 300, so the first control module 23 switches the working mode of the weighing device 200 from the ordinary weighing mode to the quantitative control mode at this time.

[0089] For example, when the first control module 23 detects that the first connecting port 210 is not connected to the second connecting port 310, it can be determined that the weighing device 200 is connected with the discharging device 300 and the weighing device 200 can control the discharging device 300, so the first control module 23 switches the working mode of the weighing device 200 from the ordinary weighing mode to the quantitative control mode at this time.

[0090] In some embodiments, when the first connecting port 210 is in communication with the second connecting port 310 and the discharging device 300 is connected to the power supply, the discharging device 300 charges the weighing device 200. Thus, the weighing device 200 can be charged when the discharging device 300 is connected to the power supply, so that the weighing module 22 can be charged by the discharging device 300 while controlling the discharging device 300, thereby avoiding the weighing module 22 from being powered off during the process of controlling the discharging device 300, thereby affecting the working of the discharging device 300.

[0091] For example, when the first control module 23 detects that the first connecting port 210 is connected with the second connecting port 310 and the discharging device 300 is connected to the power supply, it indicates that the external power supply supplies power to the discharging device 300, so the discharging device 300 can be used to charge the weighing device 200 by adapting the external power supply, thereby enabling the weighing module 22 to be charged by the discharging device 300 while controlling the discharging device 300, thereby avoiding the weighing module 22 from being powered off during the process of controlling the discharging device 300, thereby affecting the working of the discharging device 300.

[0092] As Figure 4 and Figure 5 shown, in some embodiments, the screen operating device 400 includes a protective shell 41, a control module 42, an antenna module 43 and a touch control 44. The control module 42 is arranged in the protective shell 41, and the control module 42 is used to receive the powder discharging control signal sent by the weighing device 200; the antenna module 43 is arranged in the protective shell 41 and connected with the control module 42, and is used to generate a touch control signal according to the powder discharging control signal; the touch control 44 is arranged at one end of the protective shell 41 close to the control screen 34 and connected with the antenna module 43, and the touch control 44 is used to operate the control interface of the control screen 34 according to the touch control signal. Thus, the signal transmission between the weighing device 200, the control module 42 and the antenna module 43 can trigger the touch control 44 to operate the control interface of the control screen 34 without the user touching the screen operating device 400.

[0093] Wherein, the powder discharging control signal can be used to control whether the discharging device 300 performs the discharging operation, and can also be used to control the discharging parameters of the discharging device 300, etc., which are not limited here. The touch control signal can be used to control the touch control 44 to control the control screen 34, so that the discharging device 300 performs the discharging operation corresponding to the powder discharging control signal.

[0094] Specifically, the control module 42 is arranged in the protective shell 41, and the control module 42 can be connected with the first connecting port 210 through a connecting line and receive the powder discharging control signal sent by the weighing device 200. The antenna module 43 is arranged in the protective shell 41 and can be connected and fixed with the control module 42 by welding, and the antenna module 43 is used to generate a touch control signal according to the powder discharging control signal. The touch control 44 is arranged at one end of the protective shell 41 close to the control screen 34 and connected with the antenna module 43, and the touch control 44 is used to operate the control interface of the control screen 34 according to the touch control signal.

[0095] It should be noted that the product size of the screen operating device 400 can be any size, such as 42.5cm*24.8cm*16.6cm, and the product size provided by the present application can be applied to a control screen 34 with a smaller size and can be more easily fixed on the control screen 34.

Thus, the screen operating device 400 can be fixed at a specific position of the control screen 34, so that the touch control 44 can be in contact with the control interface, thereby accurately controlling the discharging device 300 to perform the corresponding discharging operation.

[0097] Exemplarily, the fixing member 45 can be fixed on the surface of the control screen 34 by means of double-sided adhesive tape, and the fixing member 45 can be fixed in position with the protective shell 41 to enable the touch control 44 to contact the control interface. In this way, the screen operation device 400 can be fixed in a specific position of the control screen 34 so that the touch control 44 can contact the control interface to accurately control the discharging device 300 to perform corresponding discharging operations.

[0098] In some embodiments, the touch control 44 comprises a touch pen head 440, and a pen tip portion 441 of the touch pen head 440 contacts a first interaction area of the control interface, the first interaction area being used to represent an area in which the screen operation device 400 performs screen operations on the control interface.

[0100] Exemplarily, the pen tip portion 441 of the touch pen head 440 can contact the first interaction area of the control interface and perform touch control in the first interaction area to control the discharging device 300 to perform discharging operations set in the first interaction area; and the user can also perform touch control in a second interaction area of the control interface by contacting the control screen 34 to control the discharging device 300 to perform discharging operations set in the second interaction area.

[0101] In some embodiments, the fixing member 45 comprises a fixing portion 451 and a supporting portion 450, the fixing portion 451 is fixed on the surface of the control screen 34, the supporting portion 450 is used to support the screen operation device 400, and the fixing portion 451 and the supporting portion 450 are arranged at a preset angle to enable the screen operation device 400 to be arranged at a preset angle to the control screen 34. In this way, by designing the angle between the screen operation device 400 and the control screen 34, the contact area between the touch control 44 and the control screen 34 can be increased, the touch control accuracy of the touch control 44 can be improved, and the touch control 44 can be prevented from failing to contact to control the discharging device 300.

[0103] Exemplarily, the fixing portion 451 and the supporting portion 450 can be arranged at an angle of 45°, and since the screen operation device 400 is arranged on the supporting portion 450, the pen tip portion 441 of the touch pen head 440 is also arranged at an angle of 45° to the control screen 34.
