Description

Technical Field

[0001] This application relates to the field of coffee and freshly made tea beverages, and more particularly to a powder dispensing device. Background Technology

[0002] In current tea-making processes, tea infusion is typically obtained by steeping tea leaves or tea bags for a certain period. However, this method requires a considerable time frame and may result in some loss of tea flavor. Therefore, some improved tea-making processes extract tea infusion by forcing a high-temperature, pressurized fluid into tea powder. To ensure the consistency of the extracted tea infusion, the ratio of tea powder to liquid must be constant. This requires operators to accurately weigh the tea powder during extraction. Similarly, extracting concentrated coffee using pressure equipment also requires operators to weigh the coffee powder before extraction.

[0003] However, if each beverage requires manual operation, it will result in low production efficiency and uncontrollable weighing accuracy. Utility Model Content

Detailed Implementation

[0036] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0037] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0038] refer to Figures 1 to 4 This application provides a powder dispensing assembly 1. The powder dispensing assembly 1 includes a powder box portion 11, a base portion 12, and a rotating portion 13. The powder box portion 11 includes a powder storage portion 111 and a connecting portion 112 connected along the height direction Z. The powder storage portion 111 encloses a powder storage space 113 forming the powder box portion 11. The powder storage space 113 is used to hold food powders such as tea powder and coffee powder. The connecting portion 112 encloses a dispensing space 114 forming the powder box portion 11. The powder storage space 113 and the dispensing space 114 are connected along the height direction Z. Therefore, food powder located in the powder storage space 113 can enter the dispensing space 114 along the height direction Z. The base portion 12 includes a receiving cavity 121 and a powder dispensing channel 122. The receiving cavity 121 extends along the height direction Z. The connecting portion 112 is inserted into the receiving cavity 121. The rotating portion 13 is rotatably disposed in the dispensing space 114 and includes dividing teeth 131 extending in the radial direction. The dividing teeth 131 divide the distribution space 114 into multiple distribution units distributed around the height direction Z. When food powder located in the powder storage space 113 enters the distribution space 114, the food powder enters the dividing units formed by the dividing teeth 131. When the rotating part 13 rotates, the food powder also rotates with the rotating part 13 under the pushing action of the dividing teeth 131.

[0039] The connecting portion 112 also includes a powder outlet 1121 that connects to the distribution space 114. One end of the powder dispensing channel 122 connects to the distribution space 114 via the powder outlet 1121, and the other end passes through the base portion 12 away from the powder box portion 11. When food powder reaches the powder outlet 1121 under the pushing action of the dividing teeth 131, since the powder outlet 1121 and the powder dispensing channel 122 are connected, the food powder can leave the base portion 12 through the powder dispensing channel 122. The base portion 12 can be used to connect with a suitable powder dispensing device. When the powder dispensing device is a manual dispensing device, the rotating portion 13 can be connected to a structure such as a rocker arm, so that the user can drive the rotating portion 13 to rotate by rotating the rocker arm, thereby realizing the powder dispensing operation of food powder in the powder storage space 113. The base portion 12 can also be connected to an automatic powder dispensing device, so that the rotating portion 13 is driven by a motor.

[0040] As can be seen, the powder dispensing component 1 of this application can be replaced as a whole as an accessory, and thus applied in different powder dispensing devices. When the powder dispensing device needs to change the food powder contained in the powder dispensing component 1, the user only needs to remove the powder dispensing component 1 as a whole and replace it with the powder dispensing component 1 containing the desired food powder. Since the rotating part 13 is disposed in the powder dispensing component 1, this arrangement eliminates the need for the user to clean the powder in the gap between the rotating structure and the box when replacing the powder dispensing component 1. This helps to improve the replacement efficiency of the powder dispensing component 1 and the uniformity of the food powder in the powder storage space 113, thereby avoiding affecting the flavor and product stability of the subsequent tea beverage.

[0041] For the sake of brevity, the width direction X, thickness direction Y, and height direction Z are provided as reference directions in the accompanying drawings. Furthermore, the width direction X, thickness direction Y, and height direction Z are all perpendicular to each other. The radial direction described in the various embodiments should be understood as the radial direction of the rotating part 13. Since the rotation axis of the rotating part 13 is parallel to the height direction Z, the radial direction of the rotating part 13 should be understood as any direction perpendicular to the height direction Z, i.e., it can be the width direction X, the thickness direction Y, or any direction between the width direction X and the thickness direction Y. Furthermore, if this application involves a component extending or moving along a certain direction, it should be understood that the extension direction or movement direction of the component has at least a partial component in that direction, and should not be understood as the extension direction or movement direction of the component being completely parallel to that direction.

[0042] The base portion 12 and the powder box portion 11 can be connected in the height direction Z by a snap-fit ​​groove 1122 provided on the outer side of the connecting portion 112. For example... Figure 4As shown, the snap-fit ​​groove 1122 includes an open section extending along the height direction Z and a fixed section extending along the radial direction. The base portion 12 is provided with a corresponding protrusion (not shown). When connecting the base portion 12 and the powder cartridge portion 11, the protrusion enters the open end, and then the user rotates the powder cartridge portion 11, thereby moving the protrusion into the fixed section. In this way, the base portion 12 and the powder cartridge portion 11 can be fixed in relative position. Of course, in other embodiments, the base portion 12 and the powder cartridge portion 11 can also be connected by a snap-fit ​​or other means. This application is not limited to this.

[0043] refer to Figure 2 and Figure 3 In some optional embodiments, the powder cartridge 11 further includes a blocking portion 115. The blocking portion 115 is disposed in the dispensing space 114 and is positioned in the height direction Z on the side of the powder outlet 1121 near the powder storage portion 111. The blocking portion 115 extends in the radial direction. The rotating portion 13 is disposed on the side of the blocking portion 115 away from the powder storage portion 111. The radial extension length of the blocking portion 115 is greater than the extension length of the dividing teeth 131. Since the blocking portion 115 is located at the upper end of the powder outlet 1121 in the height direction Z (… Figure 2 (View angle), therefore, when viewed from one side of the powder storage space 113 along the height direction Z, the shielding portion 115 can shield the dispensing unit below it. When the food powder in the powder storage space 113 tends to move towards the dispensing space 114 under the influence of gravity, this arrangement prevents the food powder in the powder storage space 113 from directly leaving the powder dispensing assembly 1 through the powder outlet 1121 and the powder dispensing channel 122. This not only helps prevent food powder from accidentally leaving the powder storage space 113 when the powder dispensing assembly 1 is vibrated, but also improves the weight accuracy of the rotating part 13 in driving the food powder out of the powder dispensing assembly 1.

[0044] For example, suppose that one rotation of the rotating part 13 can carry A grams of food powder out of the powder storage space 113 through the powder outlet 122. If the powder in the powder storage space 113 can leave the powder storage space 113 directly through the powder outlet 1121 under the action of gravity, then when the rotating part 13 rotates once, there may be more than A grams of food powder leaving the powder outlet 122. However, the setting of the blocking part 115 can prevent the powder from leaving the powder storage space 113 without passing through the distribution unit under the action of gravity. Therefore, when the rotating part 13 rotates once, the powder outlet assembly 1 can ensure that the weight of the food powder leaving the powder outlet assembly 1 is A grams as much as possible.

[0045] Furthermore, in some optional embodiments, the end of the blocking portion 115 away from the connecting portion 112 is arc-shaped in the projection along the height direction Z. The center of the arc is located on the side of the blocking portion 115 away from the connecting portion 112. Since the blocking portion 115 only needs to block the dispensing unit below it to achieve the blocking of food powder, setting the end of the blocking portion 115 away from the connecting portion 112 to be arc-shaped can avoid the blocking portion 115 reducing the flow area of ​​the dispensing space 114, which is beneficial to improving the powder dispensing efficiency.

[0046] like Figure 2 As shown, in some optional embodiments, the side of the shielding portion 115 away from the rotating portion 13 is inclined. In the height direction Z, the dimension of the shielding portion 115 closer to the connecting portion 112 is larger than the dimension farther from the connecting portion 112. This arrangement facilitates the movement of food powder from the side of the shielding portion 115 toward the powder storage space 113 into the dispensing space 114 via the inclined shielding portion 115, thereby reducing powder accumulation at the connection point between the shielding portion 115 and the connecting portion 112 and improving the utilization rate of food powder in the powder storage space 113.

[0047] When there are two dividing teeth 131, there are also two dispensing units. When there are three dividing teeth 131, there are three dispensing units. As the number of dividing teeth 131 increases, the number of dispensing units also increases accordingly. Therefore, within the limited dispensing space 114, an increase in the number of dispensing units also means a decrease in the volume of each dispensing unit. When the rotating part 13 rotates, only the food powder in the dispensing unit connected to the powder outlet 1121 can enter the powder outlet channel 122. Therefore, a decrease in the volume of the dispensing unit can reduce the weight of powder entering the powder outlet channel 122 each time, thereby improving the powder dispensing control accuracy of the powder dispensing assembly 1. However, an excessive number of dividing teeth 131 will also lead to low powder dispensing efficiency of the powder dispensing assembly 1. Therefore, in an optional embodiment, the number of dividing teeth 131 is 6-12.

[0048] Furthermore, in an optional embodiment, the dividing teeth 131 are evenly distributed around the rotation axis of the rotating part 13. Thus, since the volumes of the multiple dispensing units are identical, the accuracy of the weight of the food powder leaving the powder dispensing assembly 1 from the powder dispensing channel 122 can also be improved when the dispensing unit and the powder outlet 1121 are connected.

[0049] In some optional embodiments, along the height direction Z, the flow area between adjacent dividing teeth 131 is greater than or equal to 15 mm. 2 and less than or equal to 30mm 2 For example, the flow area could be 15mm. 2 16mm 2 17mm2 18mm 2 19mm 2 20mm 2 21mm 2 22mm 2 23mm 2 24mm 2 25mm 2 26mm 2 27mm 2 28mm 2 29mm 2 30mm 2 Or any value between these ranges. When the dimension of the rotating part 13 in the height direction Z is constant, an increase in the flow area increases the volume of the distribution unit, and correspondingly improves the powder dispensing efficiency of the powder dispensing component 1. A decrease in the flow area decreases the volume of the distribution unit, and correspondingly improves the powder dispensing accuracy of the powder dispensing component 1. A flow area within this range can ensure the powder dispensing efficiency of the powder dispensing component 1 while maintaining its powder dispensing accuracy.

[0050] Combination Figure 8 In an optional embodiment, the powder dispensing channel 122 includes a powder inlet end 1221 and a powder outlet end 1222. The powder inlet end 1221 communicates with the distribution space 114. The powder outlet end 1222 communicates with the outside. The powder dispensing channel 122 is inclined, such that the powder outlet end 1222 is radially away from the distribution space 114. This configuration allows the user or a subsequently assembled powder dispensing device to perform powder receiving operations at the powder outlet end 1222, away from the rotating part 13, avoiding interference with the drive structure 133 such as the motor. Compared to a scheme where the powder dispensing channel 122 extends radially first and then vertically (Z), the inclined powder dispensing channel 122 reduces the accumulation of food powder in the dispensing channel 122, thus reducing the decrease in powder weight accuracy.

[0051] Furthermore, the angle between the powder dispensing channel 122 and the height direction Z is greater than or equal to 30 degrees and less than or equal to 50 degrees. For example, the angle can be 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, or any value between these values. If the angle is too large, the powder dispensing channel 122 will be too gentle, which may cause the food powder in the powder dispensing channel 122 to move unevenly. If the angle is too small, the distance between the powder dispensing end 1222 and the distribution space 114 in the radial direction will be small, which may cause subsequent powder collection interference. Therefore, the angle within this range can better balance the slope of the powder dispensing channel 122 and the distance between the powder dispensing end 1222 and the distribution space 114.

[0052] Combination Figure 2 and Figure 8 In some optional embodiments, the accommodating cavity 121 extends through the base portion 12 along the height direction Z and includes an upper cavity unit 1211 and a lower cavity unit 1212 distributed along the height direction Z. The upper cavity unit 1211 has a larger radial dimension than the lower cavity unit 1212. A connecting portion 112 is inserted into the upper cavity unit 1211. The rotating portion 13 also includes a distribution structure 132 and a drive structure 133 connected along the height direction Z. A dividing tooth 131 is disposed on the distribution structure 132. The diameter of the distribution structure 132 is larger than the diameter of the drive structure 133. The drive structure 133 is disposed on the lower cavity unit 1212. One end of the drive structure 133 away from the distribution structure 132 is used for connection to a motor.

[0053] A larger diameter dispensing structure 132 is located in the upper cavity unit 1211. When the powder dispensing assembly 1 is removed from the motor along the height direction Z, the upper cavity unit 1211 can hold the dispensing structure 132 in the receiving cavity 121. Thus, when the user replaces the powder dispensing assembly 1, the entire assembly can be inserted and removed without removing the powder cartridge 11 and the base, and then removing the rotating part 13 connected to the motor. Therefore, this embodiment improves the assembly and disassembly efficiency of the powder dispensing assembly 1 and also avoids the loss of the rotating part 13 when it is a single component.

[0054] In the embodiment where the powder cartridge section 11 includes a blocking portion 115, the cooperation between the upper cavity unit 1211 and the blocking portion 115 restricts the lateral movement of the rotating part 13 in the height direction Z. Therefore, in this embodiment, when the user assembles the powder dispensing assembly 1 so that the drive structure 133 is connected to the motor, the limiting effect of the blocking portion 115 prevents the rotating part 13 from moving away from the motor. Thus, the user can more easily and quickly assemble the powder dispensing assembly 1 without having to manually fix the potentially movable rotating part 13.

[0055] Furthermore, the rotating part 13 may also include a first sealing structure 134 sleeved on the dispensing structure 132. The first sealing structure 134 is disposed at one end of the dispensing structure 132 near the driving structure 133 and abuts against the bottom wall of the upper cavity unit 1211. Because the food powder has a small particle size, it is easy for the food powder to leave the dispensing space 114 through the gap between the rotating part 13 and the accommodating cavity 121 during movement. Therefore, the first sealing structure 134 can prevent the loss of food powder, as well as corrosion and wear caused by food powder entering structures such as motors.

[0056] To improve structural compactness, in some optional embodiments, the dispensing structure 132 includes an inner groove 1321 on the side facing the drive structure 133. One end of the first sealing structure 134 is disposed in the inner groove 1321. The dimension of the first sealing structure 134 in the height direction Z is larger than the recessed dimension of the inner groove 1321. Compared to an embodiment where the first sealing structure 134 abuts against the dispensing structure 132 without the inner groove 1321, this embodiment can reduce the dimension occupied by the rotating part 13 in the height direction Z, thereby optimizing the internal space of the powder dispensing assembly 1. Furthermore, since the dimension of the first sealing structure 134 in the height direction Z is larger than the recessed dimension of the inner groove 1321, there is a certain gap between the dispensing structure 132 and the upper cavity unit 1211 in the height direction Z. This arrangement helps to reduce the friction between the rotating part 13 and the upper cavity unit 1211 during rotation, and also avoids wear of the rotating part 13 and the upper cavity unit 1211 after long-term use of the powder dispensing assembly 1.

[0057] like Figure 2 As shown, to improve the powder dispensing efficiency of the powder dispensing assembly 1, the rotating part 13 includes a connecting structure 135. The connecting structure 135 is located on the side of the rotating part 13 away from the base part 12. The connecting structure 135 extends along the height direction Z toward the powder storage space 113. The connecting structure 135 is used to connect a baffle (not shown). The baffle can be, for example, a stirring blade, a spring, or other structure. When the food powder is tea powder, the tea powder particles are small. Therefore, the static friction between the tea powder particles may become a resistance that prevents the tea powder from moving toward the dispensing space 114. The baffle can move the powder inside the powder storage space 113 when the rotating part 13 rotates, thereby breaking the static friction between the tea powder particles and causing the tea powder to move toward the dispensing space 114. The connecting structure 135 allows for the assembly of the baffle, enabling the user to assemble the baffle as needed according to the type of food powder, air humidity, etc.

[0058] Combination Figure 2 and Figure 4In some optional embodiments, the flow area of ​​the powder storage space 113 gradually decreases in the direction from the powder storage space 113 to the dispensing space 114. This arrangement avoids dead corners in the powder storage space 113, allowing the powder in the powder storage space 113 to move into the dispensing space 114 as much as possible. In this embodiment, the powder cartridge 11 also includes a shell portion 116 extending along the height direction Z. The shell portion 116 is disposed around the powder storage portion 111 and is connected to the powder storage portion 111 at the end of the powder storage portion 111 away from the connecting portion 112. Since the flow area of ​​the powder storage space 113 gradually decreases, the structural strength at the connection position between the powder storage portion 111 and the connecting portion 112 is somewhat weakened. By providing the shell portion 116 extending along the height direction Z and disposed around the powder storage portion 111, the shell portion 116 can improve the overall structural strength of the powder cartridge 11. During the replacement and insertion / removal of the powder dispensing assembly 1, the shell portion 116 serves as a force-bearing position for the user to hold. During use of the powder dispensing assembly 1, the outer casing portion 116 can extend to the top surface of the powder dispensing device. When the powder dispensing assembly 1 is subjected to a force from the radial direction, the outer casing portion 116, which extends along the height direction Z and surrounds the powder storage portion 111, can abut against the top surface of the powder dispensing device, thereby providing support and preventing breakage and damage to the powder box portion 11.

[0059] Optionally, the housing portion 116 includes a grip hole 1161 extending in the radial direction. The grip hole 1161 is located at the end of the housing portion 116 near the connecting portion 112. The grip hole 1161 allows a user to insert their hand into the grip hole 1161 to apply a force in the height direction Z to the powder dispensing assembly 1. Since the flow area of ​​the powder storage portion 111 gradually decreases towards the connecting portion 112, the space between the end of the powder storage portion 111 near the connecting portion 112 and the housing portion 116 is larger. By positioning the grip hole 1161 in this location, users with different hand sizes can extend and bend their fingers fully toward the powder storage portion 111 to hook their fingers onto the housing portion 116 at the grip hole 1161 location, thereby enabling better application of force to the powder dispensing assembly 1.

[0060] In the embodiment shown in the accompanying drawings, the powder cartridge portion 11 has a square cross-section perpendicular to the height direction Z. The outer casing portion 116 has grip holes 1161 on both its length and width directions X. That is, there are four grip holes 1161, located on different surfaces of the outer casing portion 116. This allows the user to grip the opposite surfaces from various directions, thereby raising or lowering the powder dispensing component 1. However, this should be considered exemplary and not limiting. In other embodiments, the cross-section of the powder cartridge portion 11 perpendicular to the height direction Z can be circular or polygonal. Furthermore, the number of grip holes 1161 can be one, two, three, etc. This application is not limited in this regard. Additionally, the grip holes 1161 can be strip-shaped holes as shown in the accompanying drawings, or they can be round holes, elliptical holes, etc. This application is not limited in this regard.

[0061] In various embodiments of this application, the powder cartridge portion 11 is integrally formed. The powder cartridge portion 11 can be integrally formed by 3D printing or by injection molding. The integrally formed powder cartridge portion 11 has higher structural strength. Furthermore, the integral forming process can reduce the connection gaps between the powder cartridge portions 11, thereby preventing food powder from accumulating in the gaps and causing odor and powder loss.

[0062] To improve the sealing of the powder box section 11, in some optional embodiments, such as Figure 8 As shown, the powder dispensing assembly 1 also includes a cover 14. The cover 14 is detachably disposed at the end of the powder storage portion 111 away from the connecting portion 112, and is used to close the powder storage space 113 and the dispensing space 114. For example, the cover 14 can be entirely detachable, that is, the cover 14 can be completely separated from the powder cartridge portion 11. This arrangement eliminates the need for additional mating structures in the powder cartridge portion 11, which helps reduce the manufacturing difficulty of the powder cartridge portion 11. Alternatively, the cover 14 can be pivotally connected to the powder cartridge portion 11. This arrangement helps improve the structural integrity of the powder dispensing assembly 1 and avoids the loss of parts.

[0063] The cover portion 14 includes an abutment structure 141 and a fixing structure 142. The abutment structure 141 abuts against the end of the outer shell portion 116 away from the base portion 12. The fixing structure 142 is disposed on the side of the abutment structure 141 facing the powder storage space 113 and extends along the height direction Z. The cover portion 14 also includes a second sealing structure 143. The second sealing structure 143 is sleeved on the fixing structure 142 and is sealed to the wall surface of the powder storage portion 111 facing the powder storage space 113. The cooperation between the second sealing structure 143 and the powder storage portion 111 forms a first seal in the height direction Z of the powder dispensing assembly 1. The cooperation between the abutment structure 141 and the powder storage portion 111 forms a second seal in the radial direction of the powder dispensing assembly 1. Therefore, this embodiment can maximize the sealing performance between the cover portion 14 and the powder box portion 11, thereby preventing the powder in the powder storage space 113 from getting damp and decaying.

[0064] Optionally, the cover portion 14 also includes a weight-reducing groove 144. The weight-reducing groove 144 is recessed along the height direction Z from the side of the fixing structure 142 away from the abutment structure 141. The provision of the weight-reducing groove 144 can not only reduce the overall weight of the cover portion 14, but also improve the wall thickness uniformity of the cover portion 14 at various locations, thereby improving the production yield of the cover portion 14 and avoiding stress fatigue at thickness jump positions after long-term use. Further, the cover portion 14 may also include a grid 145. The grid 145 is engaged at the end of the weight-reducing groove 144 facing the powder storage space 113. In this way, the weight-reducing groove 144 can be used to place a desiccant pack and is restrained in place by the grid 145. The perforated arrangement of the grid 145 also allows the desiccant pack in the weight-reducing groove 144 to absorb moisture in the powder storage space 113. Of course, a functional component for odor absorption, such as a carbon pack, can also be placed between the weight-reducing groove 144 and the grid 145. This application is not limited in this respect.

[0065] Based on the above embodiments, combined with Figures 5 to 8 This application also provides a powder dispensing device 100. The powder dispensing device 100 includes the powder dispensing component 1 described in the foregoing embodiments, as well as a housing component 2 and an electrical control component 3. The housing component 2 includes an inner cavity 21, an operating surface 22, and a top surface 23. The top surface 23 is located at one end of the operating surface 22 in the height direction Z. The housing component 2 includes a mating portion 24. The mating portion 24 includes an assembly groove 241 and a powder dispensing pipe 242. The assembly groove 241 is recessed from the top surface 23. At least a portion of the powder dispensing pipe 242 is located in the inner cavity 21, with one end communicating with the assembly groove 241 and the other end communicating with the outside through the operating surface 22. A base portion 12 is disposed in the assembly groove 241. The powder dispensing channel 122 communicates with the powder dispensing pipe 242. Thus, food powder in the powder storage space 113 can reach the powder dispensing pipe 242 via the distribution space 114 and the powder dispensing channel 122.

[0066] The electronic control assembly 3 includes a drive unit 32 disposed in the inner cavity 21. The drive unit 32 includes a drive shaft 321 extending along the height direction Z into the assembly tank 241. The drive shaft 321 is connected to the rotating part 13 of the powder dispensing assembly 1 assembled in the assembly tank 241 to drive the rotating part 13 to rotate. When the drive shaft 321 drives the rotating part 13 to rotate, the dispensing units communicate with the powder outlets 1121 one by one, so that the food powder can reach the powder dispensing pipe 242 through the powder dispensing channel 122.

[0067] The powder dispensing device 100 of this application comprises multiple mating parts 24 and electronic control components 3, each corresponding to a specific type. In other words, the powder dispensing device 100 can be used to assemble multiple powder dispensing components 1. Each powder dispensing component 1 can then hold different types and flavors of food powder. Thus, one powder dispensing device 100 can meet the production needs of various beverages without requiring a separate dispensing machine for each type of powder. This arrangement helps meet diverse beverage needs while reducing the number of devices required for multiple beverages. Consequently, stores with limited space do not need to place multiple devices with the same function. Therefore, the powder dispensing device 100 of this application optimizes the number of devices and the space occupied by the devices.

[0068] Of course, multiple powder dispensing components 1 can also contain the same food powder, thus accommodating simultaneous powder dispensing operations by multiple employees when beverage orders surge, improving food service efficiency. Furthermore, the number of electronic control components 3 and mating parts 24 corresponds one-to-one, allowing multiple electronic control components 3 to operate independently. Therefore, the number of powder dispensing components 1 can correspond one-to-one with the number of mating parts 24, or the number of powder dispensing components 1 can be less than the number of mating parts 24. Users of the powder dispensing device 100 can set the number of powder dispensing components 1 according to actual needs without worrying about whether a number of powder dispensing components 1 less than the number of mating parts 24 will affect the normal operation of the powder dispensing device 100.

[0069] The drive shaft 321 of the drive unit 32 can be the output shaft of a motor. That is, the output shaft of the motor extends directly into the assembly slot 241. Alternatively, the drive shaft 321 can be connected to the output shaft of the motor through a coupling or other structural component, thereby transmitting the power of the output shaft to the rotating unit 13. This arrangement allows the drive shaft 321 to be adapted to the structure of the rotating unit 13 without requiring a corresponding motor design.

[0070] The engagement between the drive shaft 321 and the rotating part 13 can be achieved, for example, by setting the drive shaft 321 as a shaft with a square cross-section, and providing a square hole at one end of the rotating part 13 facing the drive shaft 321, thereby realizing drive. Alternatively, the drive shaft 321 and the rotating part can be connected by a coupling. This application is not limited in this respect.

[0071] exist Figure 7In the illustrated embodiment, the drive unit 32 is fixed in the inner cavity 21 by a drive bracket 322, thereby enabling it to connect with the powder dispensing assembly 1 in the height direction Z. However, this application does not limit the specific structure of the drive bracket 322 or its position in the inner cavity 21. Those skilled in the art can adapt it according to the shape, size, and weight of the motor.

[0072] In some optional embodiments, the electronic control assembly 3 further includes a weighing unit 31. The weighing unit 31 is electrically connected to the rotating unit 13. One end of the weighing unit 31 is disposed in the inner cavity 21, and the other end extends through the operating surface 22 to below the powder outlet pipe 242 in the height direction Z. Thus, the weighing unit 31 below the powder outlet pipe 242 can be used to place accessories such as measuring cups and tea powder bowls to receive food powder in the powder outlet pipe 242, and the weighing unit 31 can also obtain the weight of the received food powder. The driving unit 32 is used to control the rotation of the driving shaft 321 according to the weight received by the weighing unit 31. When the food powder has reached the expected weight, the driving unit 32 stops the rotation of the driving shaft 321. When the food powder has not yet reached the expected weight, the driving unit 32 drives the driving shaft 321 to rotate, so that the tea powder in the powder storage space 113 continues to enter the powder outlet pipe 242.

[0073] This embodiment enables the powder dispensing device 100 to achieve intelligent powder weight control, eliminating the need for the user to weigh the powder in the powder receiving accessory later. This design improves the intelligence of the beverage preparation process, thereby increasing the efficiency of beverage preparation.

[0074] The weighing unit 31 may include a weighing element 311 and a weighing bracket 312. The weighing element 311 is disposed in the inner cavity 21, and one end of the weighing bracket 312 is detachably connected to the weighing element 311, while the other end protrudes from the operating surface 22. The weighing bracket 312 can be used to place a powder bowl or a handle with a powder bowl. The weighing bracket 312 can be designed to fit the shape of the accessory, allowing the accessory to be placed more stably on the weighing bracket 312 for powder collection. The detachable connection between the weighing bracket 312 and the weighing element 311 allows the powder dispensing device 100 to replace the weighing bracket 312 according to different accessories, which is beneficial to improving the versatility of the powder dispensing device 100. This application does not limit the specific shape and structure of the weighing bracket 312. The weighing bracket 312 connected to the weighing element 311 allows the weight of the food powder obtained by the accessory placed on the weighing bracket 312 during powder collection to also be obtained by the weighing element 311.

[0075] like Figure 6 As shown, in an optional embodiment, the assembly groove 241 has a connecting protrusion 2411 on its surface in the height direction Z. The base portion 12 is correspondingly provided with a connecting groove 123. Figure 2Since the position and orientation of the powder channel 122 may be difficult to determine from the outside of the powder box 11, the connection groove 123 and the connection protrusion 2411 can prevent the powder channel 122 and the powder pipe 242 from not being connected when the user assembles the powder dispensing assembly 1.

[0076] Back Figure 5 The powder dispensing component 1 is disposed on the top surface 23, while the powder dispensing pipe 242 protrudes from the operating surface 22, thus the powder dispensing pipe 242 is actually inclined. The inclined powder dispensing pipe 242 facilitates the exit of food powder from the powder dispensing device 100 by gravity. In some optional embodiments, the operating surface 22 includes a first inclined portion 221 and a first vertical portion 222. The first vertical portion 222 extends parallel to the height direction Z. The first inclined portion 221 is disposed at the end of the first vertical portion 222 near the top surface 23 with an obtuse angle. The end of the powder dispensing pipe 242 away from the assembly groove 241 communicates with the outside through the first inclined portion 221. The weighing part 31 passes through the first vertical portion 222. The space between the first vertical portion 222 and the first inclined portion 221 forms a space capable of accommodating the powder receiving accessory and facilitating powder receiving operations for the user. Furthermore, the angle between the first inclined portion 221 and the first vertical portion 222 is an obtuse angle, which, compared to a right angle, improves the structural strength of the control panel and reduces the number of reinforcing parts.

[0077] In this embodiment, the plurality of mating portions 24 may be distributed along the width direction X. Furthermore, the number of mating portions 24 may be two, three, or more. This application is not limiting.

[0078] The housing assembly 2 also includes a rear surface 25. The rear surface 25 and the operating surface 22 are disposed opposite each other along the thickness direction Y. In some optional embodiments, at least some of the mating portions 24 are distributed along the thickness direction Y. For example, in an embodiment with only two mating portions 24, the two mating portions 24 are distributed along the thickness direction Y. In an embodiment with four mating portions 24 as shown in the figures, two mating portions 24 may be distributed along the thickness direction Y and two mating portions 24 may be distributed along the width direction X, thereby forming a 2x2 matrix distribution. Of course, the number of mating portions 24 may be more, such as six, eight, etc., and this application is not limited in this respect.

[0079] In this embodiment, the operating surface 22 further includes a second inclined portion 223 and a second vertical portion 224. The second vertical portion 224 is parallel to the height direction Z. The second vertical portion 224 is closer to the rear surface 25 relative to the first vertical portion 222. The second inclined portion 223 connects the first vertical portion 222 and the second vertical portion 224.

[0080] The mating part 24 located near the operating surface 22 is referred to as the first mating part 24, and the mating part 24 located away from the operating surface 22 is referred to as the second mating part 24. The electronic control component 3 that mates with the first mating part 24 is referred to as the first electronic control component 3, and the electronic control component 3 that mates with the second mating part 24 is referred to as the second electronic control component 3.

[0081] In this configuration, the powder outlet pipe 242a of the first mating part 24 is disposed in the first inclined portion 221. The weighing part 31a of the first electronic control component 3 passes through the first vertical portion 222. The powder outlet pipe 242b of the second mating part 24 is disposed in the second inclined portion 223. The weighing part 31b of the second electronic control component 3 passes through the first vertical portion 222. With this configuration, the powder outlet pipes 242 of the two mating parts 24 in the thickness direction Y can be distributed along the height direction Z. Furthermore, since the second mating part 24 is closer to the rear surface 25, the distance between it and the operating surface 22 in the thickness direction Y is increased. Based on the fact that the second vertical portion 224 is closer to the rear surface 25, and the first vertical portion 222 and the second vertical portion 224 are connected by the inclined second inclined portion 223, the angle between the powder outlet pipe 242b of the second mating part 24 and the height direction Z can be controlled, thereby reducing the difficulty of structural design in the inner cavity 21.

[0082] The included angle between the second vertical portion 224 and the second inclined portion 223 is greater than or equal to 100° and less than or equal to 120°. For example, the included angle can be any value between 100°, 101°, 102°, 103°, 104°, 105°, 106°, 107°, 108°, 109°, 110°, 111°, 112°, 113°, 114°, 115°, 116°, 117°, 118°, 119°, and 120°. If the included angle is too large, it increases the dimensions of the second vertical portion 224 and the second inclined portion 223 in the height direction Z, or reduces the installation space for the powder outlet pipe 242 or the weighing part 31. If the included angle is too small, it is difficult to create clearance space for the user to place or remove the powder receiving accessory.

[0083] Similarly, the included angle between the first vertical portion 222 and the first inclined portion 221 is greater than or equal to 105° and less than or equal to 125°. For example, the included angle can be any value between 105°, 106°, 107°, 108°, 109°, 110°, 111°, 112°, 113°, 114°, 115°, 116°, 117°, 118°, 119°, 120°, 121°, 122°, 123°, 124°, and 125°.

[0084] like Figure 7As shown, in some optional embodiments, the angle between the powder outlet pipe 242 and the height direction Z is smaller than the angle between the powder outlet channel 122 and the height direction Z. The angle between the powder outlet channel 122 and the height direction Z, as described above, determines the distance in the thickness direction Y between the powder outlet end 1222 of the powder outlet channel 122 and the rotating part 13. Since one end of the powder outlet pipe 242 is connected to the powder outlet end 1222, the interference between the powder outlet pipe 242 and the rotating part 13 does not actually need to be considered. In this case, the smaller angle between the powder outlet pipe 242 and the height direction Z helps to increase the speed at which the food powder leaves the powder outlet pipe 242 under gravity, thereby improving the powder outlet efficiency.

[0085] Optionally, the angle between the powder dispensing pipe 242 and the height direction Z is greater than or equal to 15° and less than or equal to 30°. For example, the angle can be any value between 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, and 30°. Reducing the angle between the powder dispensing pipe 242 and the height direction Z can decrease the distance between the powder dispensing end 1222 and the operating panel in the thickness direction Y, thereby optimizing the volume of the powder dispensing device 100 in the thickness direction Y. In addition, reducing the angle between the powder dispensing pipe 242 and the height direction Z can also increase the falling speed of food powder in the powder dispensing pipe 242, thereby increasing the powder dispensing rate. However, if the angle between the powder dispensing pipe 242 and the height direction Z is too small, it will result in a longer dimension of the powder dispensing pipe 242 that needs to be exposed from the operating surface 22. Therefore, the included angle within this range can better balance the size of the powder outlet pipe 242 and the powder outlet efficiency.

[0086] In an optional embodiment, the plurality of powder outlet pipes 242 are parallel to each other. Parallel powder outlet pipes 242 not only facilitate assembly and internal space design, but also reduce the number of parts to be manufactured. For example, as shown in the figures, the powder outlet pipes 242 of the two mating portions 24 near the operation panel in the thickness direction Y can be interchangeable, and the powder outlet pipes 242 of the two mating portions 24 far from the operation panel can also be interchangeable.

[0087] In some optional embodiments, the powder dispensing device 100 further includes an electrically connected camera component 34. The camera component 34 is disposed on the operating surface 22 and electrically connected to the electronic control component 3, and is used to acquire image information such as QR codes or barcodes corresponding to the beverage. The electronic control component 3 controls the drive unit 32 to operate based on this image information, thereby causing the desired food powder to exit from the corresponding powder dispensing component 1 through the powder dispensing pipe 242. This embodiment eliminates the need for manual powder dispensing operation by the user, thus improving beverage preparation efficiency.

[0088] Furthermore, the electronic control assembly 3 also includes a control unit and a light-emitting part 36 exposed from the operating surface 22. The control unit is disposed in the inner cavity and is electrically connected to the light-emitting part 36 and the drive unit 32. The light-emitting part 36 is disposed adjacent to the weighing part 31. The control unit controls the light-emitting part 36 to light up when the drive unit 32 is working. Since the mating part 24 and the electronic control assembly 3 of the powder dispensing device 100 of this application include multiple parts, it may be difficult for the user to place the powder receiving accessory on the correct weighing part 31 for powder receiving operation. Therefore, the controller of this embodiment can control the light-emitting part 36 at the position of the weighing part 31 to light up when the corresponding drive unit 32 is working, thereby prompting the user that the powder dispensing pipe 242 above the weighing part 31 is about to perform a powder dispensing operation.

[0089] In an optional embodiment, the powder dispensing device 100 further includes a display screen assembly 35 disposed on the operating surface 22. The display screen assembly 35 can, for example, display information such as the type of food powder in the powder assembly 1, the operating status of the drive unit 32, and beverage recipes. Furthermore, the display screen assembly 35 can also be configured as a touchscreen, allowing users to directly control the powder dispensing device 100 by touching the touchscreen with their fingers. Optionally, the display screen assembly 35 is electrically connected to the electronic control assembly 3, thereby controlling the operation or shutdown of the electronic control assembly 3. In this way, the user can manually control the desired powder dispensing operation in the powder dispensing assembly 1 via the display screen assembly 35. This configuration reduces the number of switches in the powder dispensing device 100, improving operational convenience and aesthetic simplicity.

[0090] Optionally, the electronic control assembly 3 also includes a power switch 33 disposed on the operating surface 22. The power switch 33 can cut off or connect the power to the powder dispensing device 100. This arrangement is more convenient for the user to operate compared to the arrangement where the power switch 33 is disposed on the rear surface 25.

[0091] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
