Technical Field

[0001] This utility model belongs to the technical field of coffee machine accessories, and in particular relates to an automatic coffee capsule dispensing device. Background Technology

[0002] A capsule coffee machine is a convenient coffee processing device that uses pre-packaged coffee capsules. Common capsule coffee machines generally use a manual filling method to load coffee capsules into the brewing system, which increases the user's operating steps and difficulty, affecting the ease of use of the capsule coffee machine.

[0003] In existing automatic dispensing structures, coffee capsules are prone to tilting, which not only affects the posture of the coffee capsules entering the brewing system, but also reduces the smoothness of the dispensing process. In severe cases, it can even cause jamming during the operation of the dispensing components, affecting the normal use effect. Utility Model Content

The storage box also has two constraint inner walls, at least a portion of which is connected to both sides of the first and second limiting inner walls respectively. At least a portion of the two constraint inner walls is inclined. The first limiting inner wall, the second limiting inner wall, and at least a portion of the two constraint inner walls form the storage channel, which can be used to accommodate coffee capsules.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] This embodiment provides an automatic coffee capsule dispensing device, such as... Figure 1 and Figure 2 As shown, the automatic coffee capsule dispensing device includes a storage box 100 for storing coffee capsules 800. The storage box 100 has a storage channel 200, an inlet opening 210, and an outlet opening 220, with the storage channel 200 connecting the inlet opening 210 and the outlet opening 220. In use, the inlet opening 210 allows the user to easily insert coffee capsules 800 into the storage channel 200, which provides stacking space for the coffee capsules 800. The outlet opening 220 allows the coffee capsules 800 stored in the storage channel 200 to easily leave the storage box 100, so that the coffee capsules 800 can enter the brewing system of the capsule coffee machine.

[0014] Figure 10 This is a schematic diagram of the structure of a common coffee capsule 800, such as... Figure 10As shown, a coffee capsule 800 typically includes two end portions distributed along its own axis and a sidewall portion located between the two end portions, one of which has a larger diameter and the other end portion has a smaller diameter. For ease of subsequent description, in this embodiment, the end portion with the larger diameter of the coffee capsule 800 is referred to as the flange end 810, and the end portion with the smaller diameter is referred to as the injection end 820.

[0015] In actual operation, to ensure sufficient contact between the high-pressure hot water and the coffee powder encapsulated inside the coffee capsule 800, the brewing system needs to simultaneously puncture both the flange end 810 and the injection end 820 of the coffee capsule 800. Therefore, when the coffee capsule 800 enters the brewing system, it is necessary to ensure that the axial direction of the coffee capsule 800 is parallel to the direction of movement of the brewing cup inside the brewing system. Correspondingly, the stacking direction of the coffee capsules 800 inside the automatic dispensing device should be perpendicular to their own axial direction. However, due to the diameter difference between the flange end 810 and the injection end 820 of the coffee capsule 800, a large stacking gap will form between the injection ends 820 when the flange ends 810 of two adjacent coffee capsules 800 come into contact due to stacking. The existence of the stacking gap will cause the coffee capsule 800 to tilt along its own axial direction, which will not only affect the posture of the coffee capsule 800 entering the brewing system, but also reduce the smoothness of the dispensing of the coffee capsule 800. In severe cases, it may even induce jamming and affect the normal use effect. In addition, since each coffee capsule 800 is a cup-shaped structure, the sidewalls between its two ends are curved. Therefore, when stacked, adjacent coffee capsules 800 may be misaligned due to their small contact area, which increases the difficulty for the coffee capsules 800 to detach from the automatic dispensing device. It also makes it difficult for the coffee capsules 800 to be aligned with the brewing cup in the brewing system after leaving the automatic dispensing device.

[0016] To address this issue, the storage box 100 in this embodiment has a first limiting inner wall 110, a second limiting inner wall 120, and two constraining inner walls 140. For example... Figure 3As shown, the second limiting inner wall 120 and the first limiting inner wall 110 are disposed opposite to each other. At least a portion of the two constraint inner walls 140 are respectively connected to the two sides of the first limiting inner wall 110 and the second limiting inner wall 120. At least a portion of the two constraint inner walls 140 are inclined surfaces, and a storage channel 200 for accommodating the coffee capsule 800 is formed by the first limiting inner wall 110, the second limiting inner wall 120, and at least a portion of the two constraint inner walls 140. When the coffee capsule 800 enters the storage channel 200, the first limiting inner wall 110 and the second limiting inner wall 120 can guide and limit the two end faces of the coffee capsule 800 respectively, preventing the coffee capsule 800 from tilting along its own axis. At the same time, the two constraint inner walls 140 can also limit the side walls of the coffee capsule 800 respectively, preventing the coffee capsule 800 from being misaligned or shifted. In addition, each inner wall of constraint 140 has at least a portion of an inclined surface, which can better fit the shape of the side wall of coffee capsule 800 and enhance the constraint and limiting effect of the inner wall of constraint 140 on coffee capsule 800.

[0017] This embodiment provides an automatic coffee capsule dispensing device. At least a portion of the first limiting inner wall 110, the second limiting inner wall 120, and the constraining inner wall 140 form a storage channel 200 for accommodating coffee capsules 800. The first and second limiting inner walls 110 and 120 respectively guide and limit the two end faces of the coffee capsule 800, preventing the coffee capsule 800 from tilting along its own axis. This prevents the coffee capsule 800 from getting stuck inside the storage channel 200 and ensures the correct posture of the coffee capsule 800 when entering the brewing system. Simultaneously, the constraining inner wall 140 constrains and limits the sidewalls of the coffee capsule 800, preventing misalignment and reducing the difficulty of the coffee capsule 800 detaching from the storage channel 200. It also facilitates the alignment of the coffee capsule 800 with the brewing cup in the brewing system.

[0018] Figure 4 This is a cross-sectional view of the device after the coffee capsule 800 has been inserted into the storage channel 200. (See image below.) Figure 4 As shown, when the coffee capsule 800 enters the storage channel 200, the first limiting inner wall 110 and the second limiting inner wall 120 are respectively opposite to the two end faces of the coffee capsule 800. Specifically, the first limiting inner wall 110 is opposite to the flange end 810 of the coffee capsule 800, and the second limiting inner wall 120 is opposite to the injection end 820 of the coffee capsule 800, thereby guiding and limiting the two end faces of the coffee capsule 800. Simultaneously, the two constraint inner walls 140 are located on the outer sides of the side walls of the coffee capsule 800, thereby constraining and limiting the side walls of the coffee capsule 800.

[0019] Since the axial length of a typical coffee capsule 800 is generally 30mm, to ensure that the first limiting inner wall 110 and the second limiting inner wall 120 in this embodiment can effectively guide and limit the posture of the coffee capsule 800 and prevent the coffee capsule 800 from moving sluggishly inside the storage channel 200, the distance D between the first limiting inner wall 110 and the second limiting inner wall 120 should satisfy: 30mm < D ≤ 33mm. After the coffee capsule 800 enters the storage channel 200, the distance between the first limiting inner wall 110 and the second limiting inner wall 120 will be slightly larger than the axial length of the coffee capsule 800, thus ensuring that the coffee capsule 800 can move smoothly inside the storage channel 200. Meanwhile, under the aforementioned spacing constraints, although a stacking gap still exists between the injection ends 820 of two adjacent coffee capsules 800, the allowance for the coffee capsules 800 to tilt along their own axis within the storage channel 200 will be reduced. This effectively reduces the tilting degree of each coffee capsule 800, preventing jamming caused by tilting of multiple stacked coffee capsules 800. Correspondingly, since the coffee capsules 800 cannot tilt excessively under the guidance and restraint of the first limiting inner wall 110 and the second limiting inner wall 120, their axis can remain approximately parallel to the direction of movement of the brewing cup after they detach from the device and enter the brewing system. When the coffee capsule 800 contacts the brewing cup, the contact between the inner wall of the brewing cup and the outer wall of the coffee capsule 800 further corrects the posture of the coffee capsule 800, ensuring that it smoothly enters the brewing cup.

[0020] It should be noted that after the coffee capsule 800 enters the storage channel 200, the coffee capsule 800 should be placed as centrally as possible, that is, a first limiting gap 230 is formed between the first limiting inner wall 110 and the flange end 810, and a second limiting gap 240 is formed between the second limiting inner wall 120 and the injection end 820, so as to ensure the smooth movement of the coffee capsule 800 inside the storage channel 200.

[0021] Optionally, since common coffee capsules 800 generally have a guide cone surface at the edge of the injection end 820, in order to improve the conformal fitting effect between the inner constraint wall 140 and the side wall of the coffee capsule 800, the inner constraint wall 140 in this embodiment may include a first constraint segment 141 and a second constraint segment 142. The first constraint segment 141 is connected to the first limiting inner wall 110, and the second constraint segment 142 is connected to the second limiting inner wall 120. An angle should exist between the plane containing the first constraint segment 141 and the plane containing the second constraint segment 142. When the coffee capsule 800 enters the storage channel 200, the first constraint segment 141 will constrain and limit the side wall of the coffee capsule 800, and the second constraint segment 142 will constrain and limit the guide cone surface at the edge of the injection end 820, thereby improving the constraining and limiting effect of the inner constraint wall 140 on the coffee capsule 800.

[0022] In addition, to improve the structural strength of the storage box 100, the outer wall of the storage box 100 may also have a reinforcing rib 150, and the reinforcing rib 150 should be located between the first constraint section 141 and the second constraint section 142, so as to reinforce the bent part of the constraint inner wall 140.

[0023] It should be noted that during the production and processing of the storage box 100, the workers should determine the spacing between the two constraint inner walls 140 according to the diameter specifications of various parts of the coffee capsule 800. This ensures that there is a suitable constraint gap 250 between the constraint inner wall 140 and the side wall of the coffee capsule 800, thereby suppressing the positional deviation of the coffee capsule 800 without hindering its smooth descent. Correspondingly, the angle between the plane containing the first constraint segment 141 and the plane containing the second constraint segment 142 should also be set according to the slope of the guide cone surface on the coffee capsule 800, so that the first constraint segment 141 and the second constraint segment 142 respectively produce a good constraint effect with the side wall and the guide cone surface of the coffee capsule 800.

[0024] As an optional implementation of this embodiment, since common coffee capsules 800 have a capsule collar 830 for compression sealing on the outer peripheral wall of the flange end 810, to improve the adaptability of this device to the capsule collar 830, a collar guide groove 143 may be provided at the end of the first constraint section 141 near the first limiting inner wall 110, so that the capsule collar 830 can be accommodated by the collar guide groove 143 after the coffee capsule 800 enters the storage channel 200. In addition, in this embodiment, at least a portion of the first constraint section 141 should be inclined inward and narrowed along the direction from the first limiting inner wall 110 to the second limiting inner wall 120, so as to cope with the diameter change of the side wall of the coffee capsule 800 and further improve the conformity between the first constraint section 141 and the coffee capsule 800.

[0025] To ensure that the multiple coffee capsules 800 stacked inside the storage box 100 leave the storage channel 200 one by one, the automatic coffee capsule dispensing device in this embodiment may further include a baffle unit, which should include a connecting plate 300 and a baffle assembly. Specifically, to achieve assembly between the baffle unit and the storage box 100, the second limiting inner wall 120 should have a receiving hole 121. During assembly, the connecting plate 300 is rotatably disposed inside the receiving hole 121, and the rotation axis of the connecting plate 300 should be perpendicular to the second limiting inner wall 120. After assembly is completed, the baffle assembly should be located on the end face of the connecting plate 300 near the first limiting inner wall 110, and the baffle assembly should be eccentrically positioned relative to the rotation center of the connecting plate 300.

[0026] When the coffee capsule 800 at the bottom of the storage channel 200 moves to the position of the baffle unit, the baffle assembly supports the side wall of the coffee capsule 800 near the injection end 820, thereby preventing the coffee capsule 800 from falling further. When a discharge command is received, the connecting plate 300 will rotate. Since the baffle assembly is eccentrically set on the connecting plate 300, it will rotate around the rotation axis of the connecting plate 300, so that the baffle assembly rotates between the bottom coffee capsule 800 and the second-to-last coffee capsule 800. At this time, the bottom coffee capsule 800 will leave the storage channel 200 through the discharge opening 220, and the baffle assembly will block the second-to-last coffee capsule 800, so as to achieve the purpose of the coffee capsules 800 leaving the storage channel 200 one by one. The connecting plate 300 will then continue to rotate, thereby removing the obstruction effect of the baffle assembly on the penultimate coffee capsule 800, allowing the penultimate coffee capsule 800 to fall to the position of the baffle unit. Next, the baffle assembly will support the penultimate coffee capsule 800 again, inhibiting its further descent, in preparation for the next dispensing command.

[0027] Optionally, to achieve rotational drive of the connecting disk 300, such as Figure 5 As shown, the material blocking unit may also include a mounting bracket 500 and a stepper motor 400. The mounting bracket 500 is assembled and connected to the storage box 100, the stepper motor 400 is assembled and connected to the mounting bracket 500, and the output shaft of the stepper motor 400 is assembled and connected to the connecting plate 300.

[0028] It should be noted that the assembly connection between the stepper motor 400, the mounting bracket 500, and the storage box 100 in this embodiment can be achieved using a bolt connection method commonly used in the prior art. In this case, mounting screw holes for accommodating bolts should be provided on the stepper motor 400, the mounting bracket 500, and the storage box 100. Correspondingly, those skilled in the art can also use, for example, snap-fit ​​connections or other existing connection structures to achieve the assembly connection between the above components, to ensure good installation reliability between the stepper motor 400, the mounting bracket 500, and the storage box 100. In addition, to achieve the assembly connection between the output shaft of the stepper motor 400 and the connecting plate 300, the connecting plate 300 can be provided with a mounting hole 310. During assembly, the operator can insert the output shaft of the stepper motor 400 into the mounting hole 310 and effectively fix the output shaft of the stepper motor 400 and the connecting plate 300, so that when the output shaft of the stepper motor 400 rotates, it can input torque into the connecting plate 300, thereby driving the connecting plate 300 to rotate.

[0029] like Figure 6 As shown, the material blocking assembly in this embodiment may include an arc-shaped baffle 600, the axis of which should coincide with the rotation axis of the connecting disc 300. Figure 7 A schematic diagram illustrating the working principle when using an arc-shaped baffle 600 for the material blocking assembly, and Figure 7 The diagram, from left to right, illustrates the relative positions of the feed-stopping unit and the coffee capsule 800 at three different time stages. Figure 7 As shown in the diagram on the left, when the coffee capsule 800 at the bottom of the storage channel 200 moves to the position of the baffle unit, the inner wall of the arc-shaped baffle 600 will support the coffee capsule 800 to prevent it from falling. Upon receiving a dispensing command, the connecting plate 300 will rotate clockwise. Figure 7 As shown in the centrally located diagram, when the connecting plate 300 rotates 90°, the two ends of the arc-shaped baffle 600 will support the bottommost coffee capsule 800 and the second-to-last coffee capsule 800 respectively, thus ensuring effective contact between the arc-shaped baffle 600 and the second-to-last coffee capsule 800 before the bottommost coffee capsule 800 leaves the storage channel 200. Next, the connecting plate 300 will continue to rotate clockwise, as... Figure 7 As shown in the diagram on the right, after the connecting plate 300 rotates another 90°, the inner wall of the arc-shaped baffle 600 will no longer obstruct the bottom coffee capsule 800. Therefore, the bottom coffee capsule 800 will leave the storage channel 200 through the discharge opening 220. Meanwhile, the outer wall of the arc-shaped baffle 600 will support and obstruct the second-to-last coffee capsule 800, ensuring that only one coffee capsule 800 is discharged when the device receives a discharge command. Subsequently, the connecting plate 300 will continue to rotate 180° clockwise, thus returning to its original position. Figure 7 As shown in the diagram on the left, the second-to-last coffee capsule 800 has room to fall, and the baffle assembly will block it, thus waiting for the next dispensing command.

[0030] It should be noted that, to ensure the curved baffle 600 can smoothly perform the above actions and produce the corresponding supporting and blocking effect on the coffee capsule 800, the central angle of the curved baffle 600 should be greater than 90° and less than 180°. If the central angle of the curved baffle 600 is less than 90°, the device may discharge two coffee capsules 800 consecutively when it receives a discharge command. If the central angle of the curved baffle 600 is greater than 180°, it will obstruct the coffee capsule 800 from leaving the storage channel 200, thus affecting the normal use of the device.

[0031] Optionally, the arc-shaped baffle 600 in this embodiment may also have a first guide slope 610 and two second guide slopes 620. The first guide slope 610 is used to correct the position of the coffee capsule 800 if it has a slight tilt, and extends from the inner wall of the arc-shaped baffle 600 towards the side wall of the arc-shaped baffle 600 away from the connecting plate 300. The two second guide slopes 620 are located at both ends of the arc-shaped baffle 600, respectively, and are used to correct the position of the coffee capsule 800 if it has a slight positional deviation. The second guide slopes 620 extend from the inner wall of the arc-shaped baffle 600 towards the end face of the arc-shaped baffle 600.

[0032] When the coffee capsule 800 is slightly tilted, the first guide slope 610 can contact the side wall of the coffee capsule 800 during the rotation of the arc-shaped baffle 600, thereby lifting the injection end 820 of the coffee capsule 800 upwards to ensure that the inner wall of the arc-shaped baffle 600 can smoothly support the side wall of the coffee capsule 800. When the coffee capsule 800 is slightly misaligned, the second guide slope 620 can contact the side wall of the coffee capsule 800 during the rotation of the arc-shaped baffle 600, thereby moving the axis of the coffee capsule 800 in the direction of the rotation axis of the connecting disc 300 to ensure that the inner wall of the arc-shaped baffle 600 can smoothly support the side wall of the coffee capsule 800.

[0033] As another way to implement the material blocking component, such as Figure 8As shown, the baffle assembly can also use a baffle rod 700, and the axial direction of the baffle rod 700 should be perpendicular to the inner wall 120 of the second limit. Similar to using an arc-shaped baffle 600 as the baffle assembly, when the baffle assembly uses a baffle rod 700, the baffle rod 700 will also form different relative positions with the coffee capsules 800 inside the storage channel 200 at different time stages as the connecting plate 300 rotates, thereby controlling the coffee capsules 800 inside the storage box 100 to leave the storage channel 200 one by one. Unlike using an arc-shaped baffle 600 as the baffle assembly, when the baffle assembly only includes a baffle rod 700, since the effective blocking area of ​​the baffle rod 700 on the coffee capsules 800 is small, the connecting plate 300 should have a faster rotation speed and control precision in order to effectively block the penultimate coffee capsule 800 in time.

[0034] Optionally, to improve the blocking effect of the coffee capsule 800 when the baffle rod 700 is selected, at least two baffle rods 700 should be provided. For example... Figure 9 As shown, when two baffle rods 700 are selected as the baffle assembly, the distances from the two baffle rods 700 to the rotation center of the connecting plate 300 should be equal, and the included angle formed by the two baffle rods 700 relative to the rotation center of the connecting plate 300 should be greater than 90° and less than 180°. When two baffle rods 700 are selected as the baffle assembly, the rotation speed and control precision requirements of the connecting plate 300 will be reduced. In this case, the two baffle rods 700 can be regarded as the two ends of the arc-shaped baffle 600, so that they alternately contact different coffee capsules 800 during the rotation of the connecting plate 300, thereby causing the coffee capsules 800 in the storage box 100 to leave the storage channel 200 one by one.

[0035] In addition, to prevent the stop bar 700 from damaging the coffee capsule 800 during its movement, a chamfer can be provided on the end edge of the stop bar 700 away from the connecting plate 300 to prevent the stop bar 700 from scratching the coffee capsule 800. Simultaneously, operators can also install a rotatable roller sleeve on the stop bar 700, thereby converting the sliding friction between the stop bar 700 and the coffee capsule 800 into rolling friction, further improving the protection of the coffee capsule 800.

[0036] It should be noted that, regardless of the implementation method of the material blocking component in this embodiment, the operator needs to reasonably set the rotation speed of the connecting plate 300 according to the actual size of the coffee capsule 800 and the actual falling speed of the coffee capsule 800 inside the storage channel 200, so that the material blocking unit can correctly control the process of the coffee capsule 800 leaving the storage channel 200.

[0037] As an optional implementation of this embodiment, in order to avoid motion interference between the material blocking component and the storage box 100 during the rotation of the connecting plate 300, the storage box 100 may also have a clearance cut 130 for the material blocking component, and the clearance cut 130 should be connected to the storage channel 200, so as to provide sufficient movement space for the material blocking component by means of the clearance cut 130.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
