[0011] Furthermore, the handheld part includes a housing with the mounting cavity, and a limiting component is provided in the mounting cavity for limiting the vibration motor and the battery.

[0012] Furthermore, the limiting component includes a first limiting block and a second limiting block connected sequentially along the length direction of the housing. The first limiting block is provided with a first limiting groove, and the second limiting block is provided with a second limiting groove. The vibration motor is disposed in the first limiting groove, and the battery is disposed in the second limiting groove.

[0013] Furthermore, a clearance notch is provided on the side of the first limiting block away from the second limiting block, and the clearance notch communicates with the first limiting groove to allow the output shaft to pass through.

The first opening or the second opening is located within the first plane.

[0023] Since the vibration component in this application is installed inside the mounting cavity of the handheld part, and the object holder is connected to the vibration component, when it is necessary to weigh the powder, the user only needs to hold the handheld part of this application to simultaneously transfer the vibration component and the object holder above the receiving container. The structure is simple and easy to operate and move. At the same time, since the vibration component in this application is connected to the object holder, when the vibration component starts working, it will generate vibration and transmit the vibration to the object holder. The powder carried by the object holder will be shaken off into the receiving container under the action of vibration, and then the powder received by the receiving container will be weighed using a weighing device. During this process, because the control component is communicatively connected to both the weighing device and the vibration component, it can accurately adjust the vibration intensity of the vibration component based on the feedback signal from the weighing device. Specifically, when the weight of the powder in the receiving container approaches a predetermined value, the control component gradually reduces the vibration intensity; conversely, when the weight of the powder in the receiving container reaches the predetermined value, the control component stops the vibration component. This accurately controls the amount of powder fed into the container, avoiding inaccurate dispensing caused by inconsistent dispensing speeds and ensuring the stability and consistency of the dispensing process. The entire weighing process transfers the powder from the container to the receiving container without manual shaking, improving the automation and intelligence level of the powder dispensing device. Furthermore, the control component prevents excessive powder intake, effectively improving weighing efficiency. Attached Figure Description

Detailed Implementation

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] As mentioned in the background section, existing powder batching equipment is complex in structure, has many parts, high operating costs, and is inconvenient to move. Furthermore, when weighing powder, it is generally done by manually shaking the powder onto the weighing device, which easily leads to excessive powder being shaken off, requiring manual reduction, increasing labor costs and reducing weighing efficiency. To address these issues, the inventors of this application have designed a novel powder batching device that solves the problems of complex structure, inconvenient movement, low level of automation and intelligence, and low powder weighing efficiency in existing powder batching equipment. The powder batching device of this application will be described in detail below with reference to the accompanying drawings.

[0037] It should be noted that the "length direction of the shell 111" in this application refers to the attached... Figure 1 The direction indicated by the letter X in the middle.

[0038] See Figures 1 to 6 As shown, according to an embodiment of this application, a powder dispensing device is provided, which includes a dispensing mechanism 10, a receiving container 50, a weighing device 20, and a control component 30.

[0039] The dispensing mechanism 10 includes a handheld part 11, a vibration component 12, and a placement component 13. The placement component 13 is used to carry powder. The handheld part 11 has a mounting cavity 101. The vibration component 12 is disposed in the mounting cavity 101 and connected to the placement component 13. The vibration component 12 is configured to drive the placement component 13 to vibrate synchronously during operation. The receiving container 50 is configured to receive powder that is shaken off from the placement component 13 during vibration. The weighing device 20 is used to weigh the powder received by the receiving container 50. The control component 30 is communicatively connected to both the weighing device 20 and the vibration component 12 to process the signals transmitted by the weighing device 20 and control the vibration intensity of the vibration component 12. Exemplarily, in this embodiment, the control component 30 and the weighing device 20, as well as the control component 30 and the vibration component 12, can be connected wirelessly or wiredly. The wireless communication connection includes Bluetooth or WIFI communication.

[0040] Since the vibration component 12 in this embodiment is installed in the mounting cavity 101 of the handheld part 11, and the object holder 13 is connected to the vibration component 12, when it is necessary to weigh the powder, the user only needs to hold the handheld part 11 in this embodiment to simultaneously transfer the vibration component 12 and the object holder 13 to the receiving container 50. The structure is simple and easy to operate and move. At the same time, since the vibration component 12 in this embodiment is connected to the object holder 13, when the vibration component 12 starts to work, the vibration component 12 will generate vibration and transmit the vibration to the object holder 13. The powder carried by the object holder 13 will be shaken into the receiving container 50 under the action of vibration, and then the weighing device 20 will be used to weigh the powder received by the receiving container 50. During this process, since the control component 30 is communicatively connected to both the weighing device 20 and the vibration component 12, the control component 30 can accurately adjust the vibration intensity of the vibration component 12 based on the feedback signal from the weighing device 20. Specifically, when the weight of the powder in the receiving container 50 reaches a predetermined value, the control component 30 controls the vibration component 12 to stop working; or when the weight of the powder in the receiving container 50 approaches the predetermined value, the control component 30 controls the vibration intensity of the vibration component 12 to gradually decrease. This accurately controls the amount of powder fed into the placement component 13, avoiding inaccurate batching caused by fluctuating feeding speeds, and ensuring the stability and consistency of the batching process. The entire weighing process can transfer the powder from the placement component 13 to the receiving container 50 without manual shaking, improving the automation and intelligence level of the powder batching device. Furthermore, the control function of the control component 30 can prevent excessive powder usage, effectively improving weighing efficiency.

[0041] It is worth noting that during the weighing of the powder, the receiving container 50 is placed on the weighing device 20. Thus, when the powder falls off the object 13, the weighing device 20 can weigh the powder received by the receiving container 50 in real time.

[0042] Further, see Figure 3 As shown, the vibration assembly 12 in this embodiment includes a vibration motor 121 and a battery 122. The vibration motor 121 is disposed in the mounting cavity 101, and the output shaft 123 of the vibration motor 121 passes through the mounting cavity 101 and is connected to the object holder 13. The battery 122 is disposed in the mounting cavity 101 and spaced apart from the vibration motor 121. The control assembly 30 includes a controller 31 and a receiving component 32. The controller 31 is communicatively connected to the weighing device 20 and the receiving component 32. The controller 31 processes the signal transmitted by the weighing device 20 and transmits the signal to the receiving component 32. The receiving component 32 is disposed in the mounting cavity 101 and electrically connected to the vibration motor 121 and the battery 122. The receiving component 32 includes a communication module 33 and a vibration control module 34. The communication module 33 receives the control signal transmitted by the controller 31 and transmits the control signal to the vibration control module 34. The vibration control module 34 controls the vibration intensity of the vibration motor 121 according to the control signal transmitted by the communication module 33.

[0043] Specifically, through the coordinated operation of the controller 31, the communication module 33 of the receiving component 32, and the vibration control module 34, the vibration intensity of the vibrating motor 121 can be precisely adjusted according to the signal transmitted by the weighing device 20, thereby achieving precise control of the feeding of the placed object 13 and meeting different batching requirements. At the same time, the weighing device 20 detects the powder weight in real time and transmits the signal to the controller 31. The controller 31 adjusts the vibration intensity of the vibrating motor 121 in a timely manner according to this signal, forming a closed-loop feedback control system to ensure the dynamic accuracy of the batching process. It is worth noting that the vibration control module 34 in the receiving component 32 can preset multiple control modes, such as selecting appropriate control strategies according to different powder characteristics and batching requirements, so that the batching mechanism 10 is applicable to a variety of materials.

[0044] Furthermore, since both the vibration motor 121 and the battery 122 in this embodiment are disposed within the mounting cavity 101, and the vibration motor 121 and the battery 122 are spaced apart, the dispensing mechanism 10 has a compact structure, saving space and reducing electromagnetic interference, thus ensuring the stability and reliability of the dispensing mechanism 10. Moreover, since the output shaft 123 of the vibration motor 121 passes through the mounting cavity 101 and is connected to the placement member 13, the effective transmission of vibration energy is ensured, allowing the placement member 13 to stably vibrate synchronously with the vibration motor 121, improving the stability and consistency of the dispensing process.

[0045] Further, see Figures 3 to 4 As shown, the handheld part 11 in this embodiment includes a housing 111, the housing 111 has a mounting cavity 101, and a limiting component 40 is provided in the mounting cavity 101. The limiting component 40 is used to limit the vibration motor 121 and the battery 122.

[0046] Specifically, the limiting component 40 precisely limits the position of the vibratory motor 121, ensuring that the connection between the output shaft 123 of the vibratory motor 121 and the placement component 13 remains in a precise position. This prevents misalignment of the connection between the output shaft 123 and the placement component 13 due to displacement of the vibratory motor 121, ensuring effective transmission of vibration energy and stable vibration of the placement component 13, thereby improving the accuracy and consistency of material preparation. For the battery 122, the limiting component 40 securely holds it in a specific position within the mounting cavity 101, preventing the battery 122 from shaking or shifting during equipment operation. This ensures stable connection between the battery 122 and other electrical components, providing a reliable power supply for the normal operation of the vibratory motor 121 and other equipment.

[0047] Further, see Figures 3 to 4 As shown, the limiting component 40 in this embodiment includes a first limiting block 41 and a second limiting block 42 connected sequentially along the length direction of the housing 111. The first limiting block 41 is provided with a first limiting groove 411, and the second limiting block 42 is provided with a second limiting groove 421. The vibration motor 121 is disposed in the first limiting groove 411, and the battery 122 is disposed in the second limiting groove 421.

[0048] Specifically, when installing the vibration motor 121 and battery 122, they can simply be placed into the corresponding first limiting groove 411 and second limiting groove 421, simplifying the installation process and improving installation efficiency. Meanwhile, in this embodiment, the first limiting block 41 and the second limiting block 42 are connected sequentially along the length of the housing 111, making full use of the space in the mounting cavity 101. This allows the vibration motor 121 and battery 122 to be rationally arranged within a limited space, ensuring the normal operation of each component while avoiding wasted space.

[0049] Further, see Figure 4 As shown, in this embodiment, the first limiting block 41 is provided with an avoidance notch 415 on the side away from the second limiting block 42. The avoidance notch 415 is connected to the first limiting groove 411 so that the output shaft 123 can pass through.

[0050] Specifically, the clearance notch 415 provides a dedicated passage for the output shaft 123 of the vibration motor 121, and the clearance notch 415 is connected to the first limiting groove 411, which can ensure that the output shaft 123 can smoothly pass through the first limiting block 41, avoiding interference between the output shaft 123 and the first limiting block 41 during the passage process, and ensuring the normal connection and transmission between the vibration motor 121 and the object 13.

[0051] Further, see Figures 3 to 4 As shown, in this embodiment, the first limiting block 41 is provided with a first plane 414, and the first limiting groove 411 has a first opening 412 and a second opening 413 arranged opposite to each other along the length direction perpendicular to the housing 111. The first opening 412 or the second opening 413 is located within the first plane 414. The vibration control module 34 includes a vibration control circuit board 341, which is mounted on the first plane 414 and covers the first opening 412 or the second opening 413. That is, in this embodiment, the first opening 412 can be located within the first plane 414 and the vibration control circuit board 341 can be mounted on the first plane 414 and cover the first opening 412, or the second opening 413 can be located within the first plane 414 and the vibration control circuit board 341 can be mounted on the first plane 414 and cover the second opening 413.

[0052] Specifically, the relatively positioned first opening 412 and second opening 413 allow the vibration motor 121 to be easily inserted into or removed from the first limiting groove 411 from the side, eliminating the need for complex operations or assembly / disassembly from multiple directions, thus saving installation time. At the same time, since the vibration motor 121 typically requires connection to power cords, control lines, and other wiring, the placement of the first opening 412 and second opening 413 provides a convenient channel for wiring access, preventing wiring from crossing or tangling within the mounting cavity 101, resulting in a neater and more rational wiring arrangement.

[0053] Furthermore, the vibration control circuit board 341 is mounted on the first plane 414 of the first limiting block 41, allowing it to cover either the first opening 412 or the second opening 413. This fully utilizes the space of the first limiting block 41, effectively saving space within the mounting cavity 101 and making the entire batching mechanism 10 more compact. The vibration control circuit board 341 is mounted close to the vibration motor 121, shortening the transmission distance of the control signal, reducing signal loss and interference, and improving the transmission efficiency and accuracy of the control signal. This helps to achieve precise control of the vibration intensity of the vibration motor 121.

[0054] Further, see Figures 3 to 4As shown, in this embodiment, the second limiting block 42 is provided with a second plane 424, and the second limiting groove 421 has a third opening 422 and a fourth opening 423 arranged opposite to each other along the length direction perpendicular to the housing 111. The third opening 422 or the fourth opening 423 is located within the second plane 424. The communication module 33 includes a communication circuit board 331, which is mounted on the second plane 424 and covers the third opening 422 or the fourth opening 423. That is, in this embodiment, the third opening 422 can be located within the second plane 424 and the communication circuit board 331 can be mounted on the second plane 424 and cover the fourth opening 423, or the fourth opening 423 can be located within the second plane 424 and the communication circuit board 331 can be mounted on the second plane 424 and cover the third opening 422.

[0055] Specifically, the relatively positioned third opening 422 and fourth opening 423 allow the battery 122 to be conveniently inserted into or removed from the second limiting groove 421 from the side, eliminating the need for complex operations or assembly / disassembly from multiple directions, thus saving installation time. Simultaneously, since the battery 122 typically requires connection to power lines, control lines, and other wiring, the placement of the third opening 422 and fourth opening 423 provides a convenient channel for wiring access, preventing wiring from crossing or tangling within the mounting cavity 101, resulting in a neater and more rational wiring arrangement. Furthermore, the communication circuit board 331 is mounted on the second plane 424 on the second limiting block 42, allowing it to cover either the third opening 422 or the fourth opening 423. This fully utilizes the space of the second limiting block 42, effectively saving space within the mounting cavity 101 and making the entire dispensing mechanism 10 more compact.

[0056] Further, see Figures 1 to 3 As shown, the vibration control module 34 in this embodiment is provided with a button response unit 342, and the handheld part 11 is provided with a button operation unit 112. The button operation unit 112 is subjected to external force and contacts the button response unit 342 to turn the vibration motor 121 on or off. Exemplarily, the button operation unit 112 includes a button. It is worth noting that in other embodiments of this application, the vibration motor 121 can also be controlled to turn on and off by the controller 31 and the receiving component 32.

[0057] Specifically, the vibration motor 121 can be turned on or off simply by contacting the button operation unit 112 with the button response unit 342, without the need for complicated operating procedures or additional tools. Users can quickly and conveniently control the vibration function, improving operational efficiency. At the same time, the button operation unit 112 requires a certain amount of external force to contact the button response unit 342, which to some extent prevents accidental turning on or off of the vibration motor 121 due to accidental contact, thus improving the safety of equipment use.

[0058] Further, see Figure 2 As shown, the handheld part 11 in this embodiment is provided with a power interface 113, which is electrically connected to the battery 122. Thus, when the battery 122 needs to be charged, simply plug an external power source into the power interface 113.

[0059] Further, see Figures 5 to 6 As shown, the controller 31 in this embodiment is equipped with a control module 314, a first interface 311, a second interface 312, and a display screen 313. The control module 314 is wirelessly connected to the receiving component 32. The controller 31 is electrically connected to an external power supply through the first interface 311. The weighing device 20 is electrically connected to the control module 314 through the second interface 312. The display screen 313 is used to display the weight of the weighing device 20.

[0060] Specifically, since the receiving component 32 in this embodiment is located inside the mounting cavity 101 of the handheld part 11, and the receiving component 32 is wirelessly connected to the control module 314, there is no need for a cable connection between the receiving component 32 and the control module 314. This allows the handheld part 11 to be free from the limitations of cable length and position, enabling the user to move the handheld part 11 freely within a certain range, thus improving the ease of use of the dispensing mechanism 10. Meanwhile, the first interface 311 provides stable and continuous power to the controller 31, ensuring its normal operation and the stable operation of components such as the control module 314 and the display screen 313, preventing system failures or data loss due to insufficient or fluctuating circuitry. The second interface 312 provides a direct and stable connection channel between the weighing device 20 and the control module 314, ensuring accurate and rapid transmission of weighing data, avoiding interference and data loss during transmission, and guaranteeing the accuracy and reliability of the weighing results. In addition, users can directly read the weight data measured by the weighing device 20 from the display screen 313 without having to obtain information through other complicated methods, which improves the readability and visibility of the data and makes it easier for users to quickly understand the weighing results.

[0061] In other words, when the powder is shaken from the container 13 into the receiving container 50 by the vibration of the vibration component 12, the user can read the weight data measured by the weighing device 20 from the display screen 313. Since the weighing device 20 is electrically connected to the control module 314 via the second interface 312, and the control module 314 is wirelessly connected to the receiving component 32, and the receiving component 32 is electrically connected to the vibration motor 121, when the control module 314 detects that the weight data measured by the weighing device 20 is close to a predetermined value, the control module 314 sends a vibration intensity reduction signal to the receiving component 32. The communication module 33 of the receiving component 32 receives this signal. After the signal is received, it will be transmitted to the vibration control module 34. The vibration control module 34 can reduce the vibration intensity of the vibration motor 121 according to the signal transmitted by the communication module 33, thereby reducing the vibration intensity of the object 13 to reduce the amount of powder falling off, and thus making the weight of the powder in the receiving container 50 slowly approach the predetermined value. When the control module 314 detects that the weight data measured by the weighing device 20 has reached the predetermined value, the control module 314 sends a stop signal to the communication module 33 in the receiving component 32. The communication module 33 transmits the signal to the vibration control module 34, and the vibration control module 34 will control the vibration motor 121 to stop vibrating.

[0062] Furthermore, the weighing device 20 in this embodiment includes a balance. Specifically, since the balance has high measurement accuracy, it can accurately measure the mass of the powder. It is worth noting that when weighing the powder using the balance, the receiving container 50 can be placed on the balance to catch the powder that falls off the container 13.

[0063] Furthermore, the receiving container 50 in this embodiment includes a beaker. Of course, in other embodiments of this application, the receiving container 50 can also be set as weighing paper, a flask, etc. Any other modifications within the concept of this application are within the protection scope of this application.

[0064] Further, see Figures 1 to 2 As shown, in this embodiment, the object holder 13 is detachably connected to the vibration assembly 12 via the connecting rod 14, and the cross-sectional area of ​​the connecting rod 14 (the area of ​​the cross section obtained by cutting the connecting rod 14 along the direction perpendicular to the length of the connecting rod 14) gradually decreases along the direction away from the vibration assembly 12.

[0065] Specifically, the detachable connection simplifies and facilitates the assembly and disassembly of the storage component 13 and the vibration assembly 12, eliminating the need for complex tools and operations. When maintenance or replacement of the storage component 13 or the vibration assembly 12 is required, they can be quickly separated, improving maintenance efficiency and reducing maintenance costs. Simultaneously, because the cross-sectional area of ​​the connecting rod 14 in this embodiment gradually decreases in the direction away from the vibration assembly 12, this design helps to more effectively transmit the vibration generated by the vibration assembly 12 to the storage component 13. This is because a smaller cross-sectional area can amplify the vibration during transmission, resulting in a more pronounced vibration effect on the storage component 13, thereby improving the efficiency and effectiveness of vibration control. Furthermore, the gradually decreasing cross-sectional area of ​​the connecting rod 14 brings its center of gravity closer to the vibration assembly 12, enhancing the stability of the entire connection structure and effectively improving the reliability of the dispensing mechanism 10.

[0066] Specifically, in this embodiment, the connecting rod 14 and the object placement 13 can be connected by means of screwing, welding or snap-fitting. Any other modifications under the concept of this application are within the protection scope of this application.

[0067] Further, see Figures 1 to 2 As shown, the storage component 13 in this embodiment includes a storage cavity 131, a feeding channel 132, and a discharging channel 133. Both the feeding channel 132 and the discharging channel 133 are connected to the storage cavity 131. Along the direction away from the storage cavity 131, the flow cross-section of the discharging channel 133 gradually decreases. It can be understood that the flow cross-section of the discharging channel 133 refers to the cross-section obtained by cutting the discharging channel 133 along a direction perpendicular to the material flow.

[0068] Specifically, the powder enters the storage chamber 131 from the feeding channel 132 and leaves the storage chamber 131 from the discharge channel 133 under the vibration of the vibration component 12. During this process, as the flow cross section gradually decreases, the flow space of the powder in the discharge channel 133 becomes narrower, thereby precisely controlling the discharge speed of the powder and preventing the powder from being shaken off in large quantities under the vibration of the vibration component 12, which would cause excessive powder. This eliminates the need for manual powder reduction and effectively improves weighing efficiency.

[0069] Specifically, the operation flow of the powder dispensing device in this application is as follows:

[0070] (1) Set the target weight value of the powder and the vibration intensity of the vibration motor 121 in the controller 31;

[0071] (2) Place the receiving container 50 on the balance and tare and zero the weight of the receiving container 50;

[0072] (3) Use the container 13 to carry the powder, and then move the container 13 carrying the powder to the top of the beaker by moving the hand handle 11.

[0073] (4) The vibration assembly 12 is turned on by the button operation unit 112, and the powder is shaken from the discharge channel 133 into the receiving container 50 under the vibration of the vibration assembly 12.

[0074] (5) The vibration intensity of the vibration motor 121 is controlled by the control module 314, the communication module 33 and the vibration control module 34. When the weight of the powder in the receiving container 50 is close to the target weight value, the control module 314 transmits a vibration intensity reduction signal to the communication module 33. The communication module 33 transmits the signal to the vibration control module 34, and the vibration control module 34 controls the vibration intensity of the vibration motor 121 to reduce the amount of powder falling and make the weight of the powder gradually approach the target weight value. When the weight of the powder in the receiving container 50 reaches the target weight value, the control module 314 transmits a stop signal to the communication module 33. The communication module 33 transmits the signal to the vibration control module 34, and the vibration control module 34 controls the vibration motor 121 to stop vibrating.

[0075] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0076] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0077] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
