Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a powder pressing machine and a powder pressing method thereof. Background Art

[0002] With the improvement of living standards, coffee has gradually become an integral part of people's lives. In order to meet consumers' demand for coffee freshness, coffee machines with automatic bean grinding and powder pressing functions have appeared on the market, that is, the bean grinding function and the powder pressing function are realized in the same machine.

[0003] The existing powder pressing mechanism includes a powder pressing component (powder pressing wheel). The rotating powder pressing component compacts the coffee powder that falls from the bean grinding mechanism into the powder receiving device. As the coffee powder in the powder receiving device accumulates, the powder pressing component rotates and gradually moves upward. The user quantifies the powder material by the distance the powder pressing component moves upward. The powder pressing component stops only when it rises to a predetermined height. In the prior art, the position of the powder pressing component is generally sensed by a micro switch or a photoelectric switch, and then a signal is transmitted to a processor, which determines whether the powder material in the powder receiving device has reached a specified quantity, thereby determining whether the bean grinding mechanism needs to continue to transport coffee powder to the powder receiving device and whether the powder pressing component needs to continue to press the powder. However, sensing the position of the powder pressing component by a micro switch or a photoelectric switch not only makes the cost of the coffee machine higher, but also the sensors such as the micro switch or the photoelectric switch have assembly errors. The micro switch or the photoelectric switch is prone to errors when sensing the position of the powder pressing component, which will lead to inaccurate powder quantity during pressing.

[0041] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "communication", "abutment", and "clamping" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Unless otherwise specified or defined, in the description of the invention, it should be understood that the terms "first", "second", etc. are used in the invention to describe various information, but such information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0045] Unless specifically stated or defined otherwise, the term "and / or" used in the present invention includes any and all combinations of one or more of the associated listed items.

[0046] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent with the left and right directions mentioned below. Figure 1 The left and right directions are consistent.

[0047] like Figures 1 to 3 As shown, a powder pressing machine comprises a main body 10, a powder pressing device 20, a trigger device 30, a control device 40, and a driver; the control device 40 is mounted on the main body 10. The powder pressing device 20 is used to compact the powder. When the powder pressing machine is used, the powder is compacted while being conveyed to the powder pressing device 20. The trigger device 30 and the control device 40 are two devices that match each other. When the trigger device 30 contacts the control device 40, the control device 40 can be triggered.

[0048] The powder pressing device 20 includes a powder receiver 21 and a powder pressing component 22; the powder receiver 21 is installed on the main body 10, and the powder pressing component 22 is located above the powder receiver 21. The powder receiver 21 is used to load powder. After the powder falls into the powder receiver 21, the powder in the powder receiver 21 is compacted by the powder pressing component 22.

[0049] The powder pressing part 22 is rotatably and slidably mounted on the main body 10, and the rotation axis of the powder pressing part 22 is vertically arranged, and the powder pressing part 22 can slide along its own rotation axis, so that the powder pressing part 22 can rotate relative to the powder receiver 21 and can move up and down at the same time, and the driver is an electric motor or a motor, and the driver is connected to the powder pressing part 22 through a transmission gear set, and the transmission gear set can change the speed of the driver, and the driver is not shown in the figure. The powder pressing part 22 is driven to rotate by the driver, so that the powder in the powder receiver 21 can be compacted during the rotation of the powder pressing part 22, and as the powder in the powder receiver 21 increases, the height of the compacted powder will increase, and the powder pressing part 22 will slide upward while rotating.

[0050] The driver is electrically connected to the control device 40, and the trigger device 30 is installed on the powder pressing component 22. The powder pressing component 22 drives the trigger device 30 to move upward when compacting the powder. The control device 40 is installed on the main body 10, and the control device 40 is located above the trigger device 30. The control device 40 is located on the moving path of the trigger device 30 in the direction away from the powder receiver 21. When the trigger device 30 moves upward in the direction away from the powder receiver 21 driven by the powder pressing component 22, the trigger device 30 abuts against the control device 40, and the signal of the control device 40 triggers and controls the driver to stop driving the powder pressing component 22 to compact the powder. In addition, when the trigger device 30 abuts against the control device 40, the control device 40 can send a signal to remind the user, for example, it can send an alarm sound, a signal light and other signals, and the user can also choose to manually turn off the driver.

[0051] When the powder press is working, the driver is started to drive the powder pressing part 22 to rotate, and the powder is transported to the powder receiver 21. As the powder in the powder receiver 21 increases, the height of the compacted powder will increase. Therefore, the powder pressing part 22 is raised while rotating. The height of the powder pressing part 22 can reflect the amount of compacted powder. The user can accurately know the position of the powder pressing part 22 through the cooperation of the trigger device 30 and the control device 40, so as to accurately know the height of the powder. When the trigger device 30 triggers the control device 40, the control device determines whether to control the driver to stop, so as to achieve accurate quantitative measurement of the powder. Compared with using a contactless sensor to sense the position of the powder pressing part 22, the present application uses the contact between the trigger device 30 and the control device 40 as the condition for the driver to stop. The user can adjust the initial position of the trigger device 30 and the control device 40 as needed. When the powder is quantitatively measured to the desired height, the trigger device 30 and the control device 40 contact each other, and then the driver is controlled to stop.

[0052] Specifically, in some embodiments, the positions of the trigger device 30 and the control device 40 can be interchanged. The control device 40 can also be other devices such as a contact switch.

[0053] Key References Figure 2 Specifically, in some embodiments, the trigger device 30 includes a conductor 301 mounted on the powder pressing component 22; the conductor 301 can be conductive, for example, an integral piece made of conductive materials such as copper plates.

[0054] The control device 40 includes a circuit board 46, a processor 45, a first conductive seat 41, and a second conductive seat 42; the first conductive seat 41 and the second conductive seat 42 are both mounted on the main body 10, and the first conductive seat 41 and the second conductive seat 42 are both located on the upward movement path of the conductor 301. When the powder pressing component 22 moves upward, the conductor 301 can simultaneously abut against the first conductive seat 41 and the second conductive seat 42. The processor 45 can control the driver to stop according to the received electrical signal.

[0055] The processor 45 is electrically connected to the driver, and a circuit breaker circuit is provided on the circuit board 46. The first conductive seat 41, the second conductive seat 42, and the processor 45 are all electrically connected to the circuit breaker circuit. The circuit breaker circuit is a non-conductive circuit. At this time, when the circuit breaker circuit is electrically connected to the processor 45, the circuit breaker circuit cannot send a signal to the processor 45. The first conductive seat 41 is electrically connected to one end of the circuit breaker circuit, and the first conductive seat 41 is electrically connected to the other end of the circuit breaker circuit. When the conductor 301 abuts against the first conductive seat 41 and the second conductive seat 42, the conductor 301, the first conductive seat 41, the second conductive seat 42, and the circuit breaker circuit jointly form a power-on circuit. The power-on circuit can transmit a signal that the circuit breaker circuit is turned on to the processor 45, and then the processor 45 controls the driver to stop. The user can also obtain a signal that the circuit breaker circuit is turned on to manually stop the driver.

[0057] Specifically, in some embodiments, the control device 40 further includes a first spring 43 and a second spring 44. The first spring 43 and the second spring 44 can prevent the conductor 301 from causing a rigid collision when it abuts against the first conductive seat 41 and the second conductive seat 42.

[0058] The first conductive seat 41 has a first sliding block 411 and a first contact rod 412; the second conductive seat 42 has a second sliding block 421 and a second contact rod 422; the first conductive seat 41 and the second conductive seat 42 have the same structure, and the first conductive seat 41 and the second conductive seat 42 are arranged from left to right. The lower ends of the first contact rod 412 and the second contact rod 422 are both provided with conductive contacts, and the conductor 301 abuts between the contacts of the first contact rod 412 and the second contact rod 422 to form a conductive circuit from the power-off circuit.

[0060] The first sliding block 411 and the first spring 43 are both installed in the first sliding cavity 111, the first spring 43 is clamped between the first sliding block 411 and the inner wall of the first sliding cavity 111, and the first spring 43 is located above the first sliding block 411. One end of the first touch rod 412 is connected to the first sliding block 411, and the other end of the first touch rod 412 passes through the first rod hole and is located on the upward moving path of the conductor 301.

One end of the second touch rod 422 is connected to the second sliding block 421, and the other end of the second touch rod 422 passes through the second rod hole and is located on the upward movement path of the conductor 301.

[0062] The first sliding block 411, the first touch rod 412, the second sliding block 421, and the second touch rod 422 are all cylinders, the first sliding block 411 and the second sliding block 421 are cylinders with larger diameters, the first touch rod 412 and the second touch rod 422 are cylinders with smaller diameters, the first sliding block 411 and the first touch rod 412 are connected with their axes aligned, and the second sliding block 421 and the second touch rod 422 are connected with their axes aligned. The diameters of the first touch rod 412, the second touch rod 422, the first rod hole, and the second rod hole are all equal.

[0063] When the conductor 301 moves upward driven by the powder pressing component 22, the conductor 301 simultaneously abuts against the first touch rod 412 and the second touch rod 422 and pushes the first sliding block 411 and the second sliding block 421 to slide upward for a certain distance, and the first spring 43 and the second spring 44 are compressed. After the compacted powder is removed, the powder pressing component 22 automatically moves downward and resets under the action of the first spring 43 and the second spring 44.

[0064] Specifically, in some embodiments, the axes of the first spring 43 and the second spring 44 are both arranged vertically. The upper end surface of the first sliding block 411 is provided with a first positioning groove 413, and the upper end surface of the second sliding block 421 is provided with a second positioning groove 423. The lower end of the first spring 43 is clamped in the first positioning groove 413, and the upper end of the first spring 43 abuts against the inner wall of the first sliding cavity 111. The lower end of the second spring 44 is clamped in the second positioning groove 423, and the upper end of the second spring 44 abuts against the inner wall of the second sliding cavity 112. The first positioning groove 413 prevents the first spring 43 from deforming in its radial direction, and the second positioning groove 423 prevents the second spring 44 from deforming in its radial direction.

[0065] like Figure 2 and Figure 4 As shown, specifically, in some embodiments, a transmission shaft 23 is provided at the upper end of the powder pressing component 22, and the transmission shaft 23 is located between the first conductive seat 41 and the second conductive seat 42. The powder pressing component 22 is connected to the driver through the transmission shaft 23, and a slot is provided on the transmission shaft 23, and the conductor 301 of the trigger device 30 is clamped on the slot of the transmission shaft 23.

[0066] Specifically, in some embodiments, a limit plate 24 is provided on the transmission shaft 23, and the limit plate 24 is located above the first shell 11 of the main body 10. The limit plate 24 and the conductor 301 are arranged at intervals along the axial direction of the transmission shaft 23, the first shell 11 of the main body 10 is provided with a sealed cavity, the conductor 301 is located in the sealed cavity, the first conductive seat 41 and the second conductive seat 42 are located at the top of the sealed cavity, and the limit plate 24 is installed at the upper end of the transmission shaft 23. When the transmission shaft 23 slides upward with the powder pressing component 22, the conductor 301 abuts against the first conductive seat 41 and the second conductive seat 42 to trigger the conductive signal of the driver to stop. After the compacted powder is taken out from the powder receiver 21, the transmission shaft 23 automatically moves downward and resets under the action of the first spring 43 and the second spring 44. When the powder pressing component 22 returns to the initial position of the powder pressing, the powder pressing component 22 just abuts against the bottom wall of the powder pressing groove 213 of the powder receiver 21, and the limit plate 24 abuts against the top of the first shell 11 to achieve positioning. The limiting plate 24 limits the lowest position of the powder pressing component 22 when it moves downward.

[0067] Specifically, in some embodiments, an external thread is provided at the upper end of the transmission shaft 23, and a shoulder is provided on the transmission shaft 23, the shoulder is located at the lower end of the external thread, the limit plate 24 is sleeved on the transmission shaft 23 through the shaft hole and abuts against the shoulder, the limit plate 24 is installed on the transmission shaft 23 through a nut, and the limit plate 24 is clamped between the nut and the shoulder.

[0068] Specifically, in some embodiments, the powder pressing component 22 includes a center seat 221 connected to the transmission shaft 23, and a pressing block 222 installed on the center seat 221; there are multiple pressing blocks 222, and the multiple pressing blocks 222 are evenly arranged on the center seat 221 along the circumference of the transmission shaft 23. In this embodiment, there are more than two pressing blocks 222. There is a powder discharge channel between adjacent pressing blocks 222, which is connected to the powder pressing groove 213.

[0069] Specifically, in some embodiments, the pressing block 222 is an arc block. Along the projection of the axial direction of the transmission shaft 23, one end of any pressing block 222 overlaps with one end of an adjacent pressing block 222. Along the projection of the radial direction of the transmission shaft 23, one end of any pressing block 222 is located above one end of an adjacent pressing block 222, and the lower powder channel is an inclined channel from top to bottom to avoid the lower powder channel from extending vertically, and the lower powder channel is not perpendicular to the bottom wall of the powder pressing groove 213. When the powder enters the lower powder channel from the powder falling channel 13, the powder first falls into the upper surface of the pressing block 222, then falls into the lower powder channel along the upper surface of the pressing block 222, and finally enters the powder pressing groove 213 along the inclined lower powder channel. The inclined lower powder channel can prevent the powder from causing blockage. When the powder pressing component 22 rotates, the upper end of the lower powder channel is located upstream of the rotation direction of the powder pressing component 22 , and the powder can enter the powder pressing groove 213 along the lower end of the inclined lower powder channel under the swing of the powder pressing component 22 .

[0070] like Figure 2 , Figures 5 to 7 As shown, specifically, in some embodiments, the first shell 11 of the main body 10 is further provided with a powder receiving chamber 113, which is located on the first shell 11 and below the sealing chamber. A support block 114 is provided on the inner wall of the powder receiving chamber 113, and a hanging ear 211 is provided on the powder receiver 21. When the powder receiver 21 is located in the powder receiving chamber 113, the hanging ear 211 abuts against the end surface of the support block 114 to achieve the installation of the powder receiver 21.

[0071] Specifically, in some embodiments, a groove matching the shape of the ear 211 is provided on the upper surface of the support block 114. The ear 211 is stuck in the groove after abutting against the support block 114. When the powder pressing component 22 rotates, the friction force of the powder pressing component 22 is prevented from driving the powder receiver 21 to rotate, thereby ensuring the compaction effect of the powder.

[0072] Specifically, in some embodiments, the number of the support blocks 114 and the number of the hanging ears 211 are both at least two, and the plurality of support blocks 114 and the plurality of hanging ears 211 are arranged at intervals along the circumference of the powder receiver 21 , with a shuttle gap 115 between adjacent support blocks 114 .

[0073] The opening of the powder receiving chamber 113 is located at the lower end of the first shell body 11 of the main body 10. When the powder receiver 21 is installed, the powder receiver 21 moves upward from the opening of the powder receiving chamber 113, and the hanging ear 211 of the powder receiver 21 passes through the shuttle gap 115 and moves to the top of the support block 114, and then the powder receiver 21 is horizontally rotated so that the hanging ear 211 is located directly above the support block 114, and finally the powder receiver 21 is placed on the support block 114 through the hanging ear 211.

[0074] Specifically, in some embodiments, the powder receiver 21 is further provided with a handle 212. The handle 212 is provided on the outer end surface of the powder receiver 21 to facilitate the installation of the powder receiver 21 in the powder receiving chamber 113 or the removal of the powder receiver 21 from the powder receiving chamber 113.

[0075] Specifically, in some embodiments, the powder receiver 21 includes a shell 215 and an inner liner 214 installed in the shell 215. The powder pressing groove 213 is provided on the inner liner 214. The shell 215 and the inner liner 214 are both circular. A hook 216 is provided around the upper end of the inner liner 214. The inner liner 214 is hung on the upper edge of the shell 215 through the hook 216. The user can replace the inner liner 214 with different inner diameters and depths to achieve quantitative measurement of different powders.

[0076] like Figure 1 As shown, a powder pressing method of a powder pressing machine comprises the following steps:

[0077] When the grinding device 50 grinds coffee beans or other particles, the driver is started to gradually convey the powder ground by the grinding device 50 into the powder receiver 21 .

[0078] After the driver is started, it drives the powder pressing component 22 to rotate, and the powder pressing component 22 compacts the powder transported into the powder receiver 21 by its own rotation.

[0079] Since the grinding device 50 continuously delivers powder to the powder pressing groove 213 of the powder receiver 21 , the powder in the powder receiver 21 increases, the thickness of the compacted powder increases, and the powder pressing component 22 rotates and slides upward in a direction away from the powder receiver 21 .

[0080] When the powder in the powder receiver 21 is compacted to a certain height, the trigger device 30 on the powder pressing component 22 abuts against and triggers the control device 40, and the grinding device 50 stops conveying the powder first, and the powder remaining in the powder falling channel 13 and above the powder pressing component 22 continues to be conveyed to the powder receiver 21, and the powder pressing component 22 is pushed upward by the continuously accumulated powder and pushes the first conductive seat 41 and the second conductive seat 42 upward, and the spring is compressed.

[0081] According to the parameters preset by the processor 45, the control device 40 controls the driver to continue rotating for eight seconds and then stop, and the powder pressing component 22 continues rotating for eight seconds and then stops rotating, and the powder pressing is completed. The powder pressing component 22 continues rotating for eight seconds and then stops rotating, ensuring that the powder is fully compacted and the quantity of the powder is guaranteed.

[0082] Finally, the powder receiver 21 is removed to obtain the compacted quantitative powder. The powder pressing component 22 moves to the initial position under the action of gravity, and the first conductive seat 41 and the second conductive seat 42 are also reset under the push of the first spring 43 and the second spring 44.

[0083] The above embodiments are not exhaustive enumerations of the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
