Description

Powder pressing machine and powder pressing resetting method

[0001] The present invention claims priority to Chinese patent application No. 2024101336047, filed with the Patent Office of China on January 30, 2024, entitled “Powder Press and Powder Press Resetting Method,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The invention belongs to the technical field of coffee machines, in particular to a powder pressing machine and a powder pressing resetting method. Background Art

[0003] In the field of coffee tamping machines, motor-driven automatic tamping components are increasingly used due to their simple operation.

[0004] In the prior art, for example, Chinese patent No. 202022543443.9 discloses a beverage or food brewing machine. The device includes an automatic quantitative powder pressing assembly, which rotates rapidly under the drive of a motor and compresses coffee powder or coffee beans. The powder pressing assembly directs the coffee powder into a powder cup container below the powder pressing wheel and acts on the coffee powder in the powder cup container through its own gravity. As the coffee powder increases, the powder pressing assembly gradually moves upward under the force of the coffee powder until it is restrained by a limit structure above, thereby achieving the quantitative and powder pressing functions of the coffee powder. When the user removes the powder cup container, the powder pressing assembly falls to its initial position under the action of gravity.

[0005] However, when the user removes the powder cup, the powder pressing assembly falls under its own weight, which can interfere with the user's ability to return to its original position due to factors such as friction between components, oil film adhesion, and the product being placed on an inclined surface. Therefore, the powder pressing assembly's own weight alone cannot guarantee accurate return to its original position, significantly reducing the device's stability.

[0023] The present invention also provides a method for resetting compressed powder of a powder pressing machine, comprising the following steps:

[0024] Step 1: Move the pushing member to the first moving position, the reset member is in the initial state, the pressing member abuts against the powder pressing component through the reset member, and the powder pressing component is in the reset state;

[0025] Step 2: Move the pushing member from the first moving position to the second moving position. The pushing member is used to resist the pressing member and drive the pressing member to move away from the powder pressing assembly. The reset member is stretched by the pressing member, and the pressing member is separated from the powder pressing assembly. The powder pressing assembly is in an operating state.

[0026] The technical solution provided by the present invention has the following advantages and effects:

[0027] 1. The powder pressing chamber is used to accommodate coffee powder, and the powder pressing assembly grinds the coffee powder in the powder pressing chamber, thereby pressing the coffee powder; the pushing member is in the first moving position, and the pushing member is separated from the pressing member. Since the two ends of the reset member are respectively installed on the pressing member and the shell, the reset member is used to apply a force to the pressing member, so that the pressing member presses the powder pressing assembly. After being pressed by the pressing member, the powder pressing assembly moves to the lowest position in the powder pressing chamber. Since the powder pressing assembly operates in the powder pressing chamber, the powder pressing assembly needs to be moved to the highest position ready for operation, and is moved to the second moving position by the pushing member. The pushing member is used to push the pressing member to move upward, so that the reset member is in a stretched state, and the pressing member is separated from the powder pressing assembly. The powder pressing assembly has space to move upward, and the powder pressing assembly compresses powder normally; after the powder compaction is completed, the pushing member moves to the first moving position, and the reset member drives the pressing member to act on the powder pressing assembly due to the reaction force generated after stretching, thereby returning the powder pressing assembly to the initial position; by setting the reset member, the pressing member resets the powder pressing assembly through the force of the reset member, and the operation is repeated, thereby improving the accurate position of the powder pressing assembly after resetting, and improving the problem that the powder pressing assembly of the existing powder pressing machine cannot be accurately reset.

[0028] 2. To facilitate the resetting of the powder pressing assembly, a clamping block is provided on the powder cup container, and a clamping slot is provided in the housing to cooperate with the clamping block. The powder pressing chamber, the clamping slot, the arc slot, and the mounting chamber are sequentially connected. When the powder pressing assembly is in the powder pressing action, the powder cup container enters the housing from the opening and is located in the powder pressing chamber. The powder cup container is used to be located below the powder pressing assembly and is used to hold the pressed coffee powder. During use, the powder cup container enters the powder pressing chamber, and at the same time, the card block of the powder cup container enters the card slot, thereby squeezing or pushing the pushing member, causing the pushing member to move from the first moving position to the second moving position. When the pushing member moves, it drives the pressing member to move, and at the same time the reset member is stretched, so that the powder pressing assembly has space to move upward. At this time, the powder pressing assembly is separated from the pressing member, and the powder pressing assembly is not restricted by the pressing member; after the powder pressing is completed, the powder cup container is removed from the powder pressing chamber, and the card block is also removed from the card slot. In the absence of the card block force on the pushing member, the reset member applies a reverse force to the pressing member, and the pressing member drives the pushing member to move from the second moving position to the first moving position, and the powder pressing assembly returns to the initial position; through the cooperation of the card block and the card slot, the powder cup container controls the pushing member to move from the first fixed position to the second moving position when in use, thereby improving the convenience of resetting the powder pressing assembly.

[0029] 3. By arranging multiple clamping blocks on the circumference of the cup body, and the clamping blocks have a second guiding inclined surface, when the cup body is installed, the cup body cooperates with the arc groove and is stuck in the arc groove, and the cup body rotates in the arc groove, so that the clamping block moves into the clamping groove. Since the pushing member has a first guiding inclined surface, when the clamping block contacts the pushing member, the first guiding inclined surface and the second guiding inclined surface contact each other. The first guiding inclined surface and the second guiding inclined surface are both used to guide the sliding cooperation between the clamping block and the moving block, reducing the force of the clamping block pushing the moving block, making it easier to push the pushing member from the first moving position to the second moving position when the cup body rotates in the slide groove, thereby improving the efficiency of the resetting mechanism and also improving the convenience of the powder pressing operation of the powder pressing machine.

[0030] 4. To improve the stability of the reset member on the housing. The housing is provided with a support column for supporting the reset member. The pressing member passes through the support column through a through hole so that the pressing member is at least partially sleeved outside the support column. Then a limiting member is installed on the support column. The limiting member is used to install the reset mechanism on the housing and limit the position of the reset mechanism on the housing. A receiving groove for accommodating the reset member is provided on the pressing member. The reset member is sleeved outside the support column, and the two ends of the reset member are respectively against the limiting member and the bottom wall of the receiving groove. When in use, when the pressing member is pushed to the second moving position by the pushing member, since the limiting member is installed on the pressing member, the pressing member pulls the reset member, so that the reset member has a reverse force for reset. When the pushing member moves to the first moving position, the reaction force of the reset member will drive the pressing member to push the compressed powder assembly to reset. Since the reset member is sleeved on the support column, the reset member moves in the length direction of the support column during stretching, thereby improving the stability of the reset member during movement.

[0031] 5. Set the sliding rod in the mounting hole of the support column. The sliding rod and the support column slide together to make the limiter move along the height direction of the support column, thereby further improving the stability of the movement of the limiter. Moreover, the outer diameter of the limiter block is larger than the outer diameter of the support column, so that the top of the support column is offset against the limiter block to determine the position of the limiter on the outer shell. The outer diameter of the support column is smaller than the inner diameter of the through hole, and the pressing piece is sleeved on the outside of the support column for easy installation.

[0032] 6. By setting the pressing block at the first end of the pressing plate, the axle pin at the second end of the pressing plate, the pressing plate is rotatably connected to the outer shell through the axle pin, the accommodating groove is located between the pressing block and the axle pin, and the reset member is set in the accommodating groove, the pressing plate forms a lever structure through the reset member and the axle pin, thereby reducing the force of the pressing block pushing the powder pressing assembly to reset through the reset member.

[0033] 7. The tamping shaft of the powder pressing assembly is used to cooperate with the driving mechanism. The tamping shaft is rotated by the driving mechanism, and the tamping shaft drives the tamping wheel to rotate. The tamping wheel is used for squeezing and grinding powder. The tamping shaft is slidably matched with the inner wall of the shell. The tamping wheel continuously moves upward when compacting the powder, and is used to grind the coffee powder in the powder cup container flat, so that the coffee powder in the powder cup container is continuously increased to reach the amount required for brewing coffee; moreover, the first abutting portion cooperates with the first limiting portion, and the second abutting portion cooperates with the second limiting portion, thereby limiting the position of the tamping wheel in the powder pressing chamber.

[0034] 8. By disposing a microswitch within the mounting cavity and electrically connecting the microswitch to a drive mechanism, the drive mechanism is used to rotate the compacting shaft of the powder compacting assembly. Since the trigger member is disposed on the pusher, movement of the pusher drives the trigger member. When the pusher is in a first movable position, the trigger member is separated from the microswitch, and the drive mechanism is inactive. When the pusher is in a second movable position, the trigger member is also moved and contacts the microswitch, thereby activating the microswitch. After the microswitch is activated, the drive mechanism begins operating and drives the compacting assembly. This arrangement allows the powder cup container to enter the compacting chamber, and the latching block engages with the latching slot, driving the pusher from the first movable position to the second movable position. This allows the pusher to both drive the pressing member, allowing the compacting assembly to move upward, and also triggers the drive mechanism to activate, enabling the compacting machine to begin compacting. This achieves the dual functions of powering on and resetting the compacting machine, while simplifying operation.

[0035] 9. The driving member is used to provide power for the driving mechanism and drives the transmission assembly through the output shaft. The transmission assembly has a driving wheel, a first transmission wheel, a second transmission wheel and a driven wheel. By setting the driving wheel, the first transmission wheel, the second transmission wheel and the driven wheel, the transmission ratio of the transmission assembly and the output direction of the power are changed to meet the powder pressing requirements of the powder pressing machine.

[0036] 10. The powder pressing and resetting method is simple to operate. The normal powder pressing operation of the powder pressing component can be achieved by simply driving the pushing member from the first moving position to the second moving position. After the powder pressing is completed, the powder pressing component is accurately reset through the reaction force of the resetting member, avoiding interference when the powder pressing component is reset, and improving the stability of the powder pressing machine.

[0053] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0054] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0055] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0056] It should be noted that when an element is considered to be "fixed to" another element, it can be directly fixed to the other element or there can be an intermediate element; when an element is considered to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element; when an element is considered to be "mounted on" another element, it can be directly mounted on the other element or there can be an intermediate element. When an element is considered to be "located on" another element, it can be directly located on the other element or there can be an intermediate element.

[0057] As shown in Figures 1 to 12, a powder pressing machine 100 includes a shell 1, a powder pressing assembly 2 and a reset mechanism 3, the reset mechanism 3 including a pushing member 33, a reset member 32 and a pressing member 31, the shell 1 has a mounting cavity 18 and a powder pressing cavity 11, the powder pressing assembly 2 is at least partially arranged in the powder pressing cavity 11, a first end of the pressing member 31 is rotatably matched with the shell 1, and a second end of the pressing member 31 is located above the powder pressing assembly 2, and two ends of the reset member 32 are respectively installed on the pressing member 31 and the shell 1; the pushing member 33 is at least partially arranged in the mounting cavity 18 and is located below the pressing member 31; wherein, the pushing member 33 has a first moving position and a second moving position, in the first moving position, the second end of the pressing member 31 is against the powder pressing assembly 2; in the second moving position, the pushing member 33 is against the pressing member 31, and the pressing member 31 is separated from the powder pressing assembly 2.

[0058] The powder pressing chamber 11 is used to accommodate coffee powder, and the powder pressing assembly 2 grinds the coffee powder in the powder pressing chamber 11, thereby pressing the coffee powder; the pushing member 33 is in the first moving position, and the pushing member 33 is separated from the pressing member 31. Since the two ends of the reset member 32 are respectively installed on the pressing member 31 and the shell 1, the reset member 32 is used to apply a force to the pressing member 31, so that the pressing member 31 presses the powder pressing assembly 2. After being pressed by the pressing member 31, the powder pressing assembly 2 moves to the lowest position in the powder pressing chamber 11, so that the powder pressing wheel 22 of the powder pressing assembly 2 contacts and rubs with the bottom wall of the powder pressing groove 54, thereby grinding out finer coffee powder. Since the powder pressing component 2 operates in the powder pressing chamber 11, before pressing the powder, the powder pressing component 2 needs to have space to move upward, and is moved to the second moving position by the pushing member 33. The pushing member 33 is used to push the pressing member 31 to move upward, so that the reset member 32 is in a stretched state, and the pressing member 31 is separated from the powder pressing component 2. The powder pressing component 2 has space to move upward, and the powder pressing component 2 compresses the powder normally; after the powder pressing is completed, the pushing member 33 moves to the first moving position, and the reset member 32 drives the pressing member 31 to act on the powder pressing component 2 due to the reaction force generated after stretching, so that the powder pressing component 2 returns to the initial position; by setting the reset member 32, the pressing member 31 resets the powder pressing component 2 through the force of the reset member 32, and the operation is repeated, thereby improving the accurate position of the powder pressing component 2 after resetting, and improving the problem that the powder pressing component 2 of the existing powder pressing machine 100 cannot be accurately reset.

[0059] In this embodiment, the tamping machine 100 is primarily used to grind coffee powder. Ground coffee powder from the grinder enters the tamping chamber 11 through a delivery conduit 12. The outlet of the delivery conduit 12 is mounted on the sidewall of the housing 1 and located above the tamping wheel 22. The grinding process of the tamping machine 100 refines the coffee powder, improving the taste of brewed coffee. In this embodiment, the resetting of the tamping assembly 2 is particularly important during the tamping process. During grinding, the tamping wheel 22 must return to its reset position. In this reset position, the tamping wheel 22 engages the bottom wall of the tamping trough 54. During rotation, the tamping wheel 22 stirs or rapidly rotates the coffee powder within the tamping chamber 11. The coffee powder enters the space between the tamping wheel 22 and the bottom wall of the tamping trough 54, where it is ground more finely and compacted, ensuring uniform distribution of the coffee powder within the tamping trough 54. Therefore, the resetting of the powder pressing assembly 2 is related to whether the coffee powder can be ground more finely and is related to the taste of the coffee powder after brewing.

[0060] To facilitate resetting the powder pressing assembly 2, as shown in Figures 1, 3, 4, and 10, the powder pressing machine 100 includes a detachable powder cup container 5. The housing 1 has an opening 14 for the powder cup container 5 to enter and exit the powder pressing chamber 11. The powder cup container 5 has a clamping block 51. The housing 1 has a clamping groove 13 and an arc groove 19. The arc groove 19 extends along the circumference of the housing 1. The powder pressing chamber 11, the clamping groove 13, the arc groove 19, and the mounting chamber 18 are sequentially connected. At least a portion of the powder cup container 5 is rotatably engaged with the arc groove 19. The pushing member 33 is at least partially located in the clamping groove 13. The clamping block 51 is used to abut against the pushing member 33 to enable the pushing member 33 to have a first movable position and a second movable position. By setting a card block 51 on the powder cup container 5, a card slot 13 that cooperates with the card block 51 is provided in the shell 1, and the powder pressing chamber 11, the card slot 13, the arc groove 19 and the installation chamber 18 are connected in sequence. When the powder pressing component 2 is pressing the powder, the powder cup container 5 enters the shell 1 from the opening 14 and is located in the powder pressing chamber 11. The powder cup container 5 is used to be located below the powder pressing component 2, and the powder cup container 5 is used to contain the pressed coffee powder.

[0061] During use, the powder cup container 5 enters the powder pressing chamber 11. After the powder cup container 5 rotates, the block 51 of the powder cup container 5 enters the card slot 13, thereby squeezing or pushing the pushing member 33, so that the pushing member 33 moves from the first moving position to the second moving position. When the pushing member 33 moves, the pressing member 31 is driven to move, and at the same time, the reset member 32 is stretched, so that the powder pressing assembly 2 has space to move upward. At this time, the powder pressing assembly 2 is separated from the pressing member 31, and the powder pressing assembly 2 is not restricted by the pressing member 31. After the powder pressing is completed, the powder cup container 5 is removed from the powder pressing chamber 11, and the block 51 of the powder cup container 5 enters the card slot 13. 51 is also removed from the card slot 13. Without the force of the block 51, the pushing member 33 will not be able to counteract the pressing member 31. The reset member 32 applies a reverse force to the pressing member 31. The pressing member 31 drives the pushing member 33 to move from the second moving position to the first moving position, and the powder pressing assembly 2 returns to the initial position. Through the cooperation of the block 51 and the card slot 13, the powder cup container 5 controls the pushing member 33 to move from the first fixed position to the second moving position when in use, and drives the pressing member 31 to move, thereby improving the convenience of resetting the powder pressing assembly 2.

[0062] As shown in Figures 2 to 6, 8 and 9, the pushing member 33 includes a moving rod 331 and a moving block 333. The moving block 333 is mounted on a first end of the moving rod 331, and a second end of the moving rod 331 is located below the pressing member 31. The moving block 333 has a first guide slope 3331. The powder cup container 5 has a cup body 52, and the cup body 52 cooperates with the arc groove 19. There are at least two clamping blocks 51, which are distributed along the circumference of the cup body 52. ​​The clamping blocks 51 have a second guide slope 511, and the inclination directions of the two second guide slopes 511 are consistent. The end of the clamping block 51 is used to slide with the first guide slope 3331, and the end of the moving block 333 is used to slide with the second guide slope 511. By arranging multiple blocks 51 on the circumference of the cup body 52, and the block 51 having a second guide slope 511, when the cup body 52 is installed, the cup body 52 cooperates with the arc groove 19 and is stuck in the arc groove 19, and the cup body 52 rotates in the arc groove 19, thereby moving the block 51 into the slot 13.

[0063] Because the pusher 33 has a first guide slope 3331, when the clamping block 51 contacts the movable block 333 of the pusher 33, the first guide slope 3331 and the second guide slope 511 contact each other. The first guide slope 3331 and the second guide slope 511 are both used to guide the clamping block 51 and the movable block 333 to slide together, reducing the force exerted by the clamping block 51 on the movable block 333. This makes it easier to push the pusher 33 from the first moving position to the second moving position when the cup 52 rotates within the chute 19, thereby improving the efficiency of the reset mechanism 3 and the convenience of the powder compacting operation of the powder compacting machine 100. In this embodiment, the powder cup container 5 has a handle 53 mounted on the outer wall of the cup 52. During use, the handle 53 is grasped to move the cup 53 into the powder compacting chamber 11.

[0064] In order to improve the stability of the reset member 32 on the housing 1, as shown in Figures 3 and 7, the reset mechanism 3 has a limiter 34, the housing 1 has a support column 17, the pressing member 31 has a through hole for the support column 17 to pass through, and the pressing member 31 has a receiving groove 311 therein, which is in communication with the through hole; the limiter 34 is mounted on the pressing member 31, and the reset member 32 is sleeved on the outside of the support column 17 and located in the receiving groove 311; the first end of the reset member 32 is mounted on the limiter 34, and the second end of the reset member 32 is mounted on the bottom wall of the receiving groove 311. The housing 1 has a support column 17 that supports the reset member 32. The pressing member 31 passes through the support column 17 through a through hole, so that the pressing member 31 is at least partially sleeved outside the support column 17, and then the limiting member 34 is installed on the support column 17. The limiting member 34 is used to install the reset mechanism 3 on the housing 1 and limit the position of the reset mechanism 3 on the housing 1. A receiving groove 311 for accommodating the reset member 32 is provided on the pressing member 31. The reset member 32 is sleeved outside the support column 17. This reset member 32 is a spring, and the two ends of the reset member 32 are respectively connected to the limiting member 34 and the bottom wall of the receiving groove 311.

[0065] During use, when the pressing member 31 is pushed to the second moving position by the pushing member 33, since the limiting member 34 is installed on the pressing member 31, the pressing member 31 pulls the reset member 32, so that the reset member 32 has a reverse force for reset. When the pushing member 33 moves to the first moving position, the reaction force of the reset member 32 will drive the pressing member 31 to push the powder pressing assembly 2 to reset. Since the reset member 32 is sleeved on the support column 17, the reset member 32 moves in the length direction of the support column 17 during the stretching delay, thereby improving the stability of the reset member 32 during movement.

[0066] As shown in FIG7 , the limiting member 34 includes a slide bar 342 and a limiting block 341. The slide bar 342 and the limiting block 341 are integrally formed. The support column 17 has a mounting hole, and the outer wall of the slide bar 342 slides in engagement with the inner wall of the mounting hole. The outer diameter of the limiting block 341 is larger than the outer diameter of the support column 17, which is smaller than the inner diameter of the through hole. The slide bar 342 is disposed in the mounting hole of the support column 17 and slides in engagement with the support column 17, allowing the limiting member 34 to move along the height direction of the support column 17, thereby further improving the stability of the movement of the limiting member 34. Furthermore, the outer diameter of the limiting block 341 is larger than the outer diameter of the support column 17, allowing the top of the support column 17 to abut against the limiting block 341, thereby determining the position of the limiting member 34 on the housing 1. The outer diameter of the support column 17 is smaller than the inner diameter of the through hole, and the pressing member 31 is sleeved over the support column 17 for easy installation.

[0067] As shown in Figures 6 and 8, the pressing member 31 includes a pressing plate 314, an axle pin 313, and a pressing block 312. The pressing block 312 is installed at the first end of the pressing plate 314, and the axle pin 313 is installed at the second end of the pressing plate 314. The pressing plate 314 is rotatably connected to the shell 1 through the axle pin 313; the accommodating groove 311 is opened on the pressing plate 314, and the accommodating groove 311 is located between the pressing block 312 and the axle pin 313. By setting the pressing block 312 at the first end of the pressing plate 314 and the axle pin 313 at the second end of the pressing plate 314, the pressing plate 314 is rotatably connected to the shell 1 through the axle pin 313, thereby limiting the range of movement and position of the pressing plate 314, and the accommodating groove 311 is located between the pressing block 312 and the axle pin 313, and the reset member 32 is arranged in the accommodating groove 311, so that the pressing plate 314 forms a lever structure through the reset member 32 and the axle pin 313, thereby reducing the force of the pressing block 312 pushing the compressed powder assembly 2 to reset through the reset member 32.

[0068] As shown in Figures 2, 3 and 11, the powder pressing assembly 2 includes a powder pressing shaft 23, a powder pressing wheel 22, a first abutment 21 and a second abutment 24, the first abutment 21 is installed on the first end of the powder pressing shaft 23, the powder pressing wheel 22 is installed on the second end of the powder pressing shaft 23, the second abutment 24 is installed on the third end of the powder pressing shaft 23, and the second abutment 24 is located between the first abutment 21 and the powder pressing wheel 22; the powder pressing wheel 22 is located in the powder pressing chamber 11, and the powder pressing shaft 23 is slidably fitted with the inner wall of the outer shell 1; the powder pressing machine 100 also includes a first limiting part 15 and a second limiting part 16, both of which are installed on the inner wall of the outer shell 1, the first abutment 21 is used to abut against the first limiting part 15, and the second abutment 24 is used to abut against the second limiting part 16. The tamping shaft 23 of the tamping assembly 2 is used to cooperate with the driving mechanism 6. The tamping shaft 23 is rotated by the driving mechanism 6, and the tamping shaft 23 drives the tamping wheel 22 to rotate. The tamping wheel 22 is used for squeezing and grinding coffee powder. The tamping shaft 23 slides with the inner wall of the shell 1. The tamping wheel 22 continuously moves upward when tamping the powder, and is used to grind the coffee powder in the powder cup container 5 flat, and make the coffee powder evenly distributed in the tamping groove 54, and also make the coffee powder in the powder cup container 5 continuously increase to reach the amount required for brewing coffee; moreover, the first abutting portion 21 cooperates with the first limiting portion 15, and the second abutting portion 24 cooperates with the second limiting portion 16, so as to limit the position of the tamping wheel 22 in the tamping chamber 11.

[0069] As shown in Figures 2 to 5 and Figure 8, the powder pressing machine 100 also includes a trigger member 332, a micro switch 4 and a driving mechanism 6. The trigger member 332 is installed on the pushing member 33 and is located in the mounting cavity 18. The driving mechanism 6 is installed on the housing 1. The micro switch 4 is installed in the mounting cavity 18, and the micro switch 4 is electrically connected to the driving mechanism 6; when the pushing member 33 is in the first moving position, the trigger member 332 is separated from the micro switch 4; when the pushing member 33 is in the second moving position, the trigger member 332 contacts the micro switch 4 and opens the micro switch 4. By setting the microswitch 4 in the installation cavity 18, the microswitch 4 is electrically connected to the driving mechanism 6, and the driving mechanism 6 is used to drive the powder pressing shaft 23 of the powder pressing assembly 2 to rotate. Since the trigger member 332 is set on the pushing member 33, the pushing member 33 drives the trigger member 332 to move when it moves; when the pushing member 33 is in the first moving position, the trigger member 332 is separated from the microswitch 4, and the driving mechanism 6 is in a stopped working state; when the pushing member 33 is in the second moving position, the trigger member 332 is also moved and contacts the microswitch 4, thereby turning on the microswitch 4. After the microswitch 4 is turned on, the driving mechanism 6 starts to operate and drives the powder pressing assembly 2 to operate.

[0070] With this arrangement of the trigger and pusher, when the powder cup container 5 enters the powder compacting chamber 11, the engaging block 51 engages with the engaging slot 13, driving the pusher 33 from the first position to the second position. This allows the pusher 33 to both drive the pressing member 31, allowing the powder compacting assembly 2 to move upward, and also triggers the drive mechanism 6 to operate, thereby opening the powder compacting machine 100 for compacting. This achieves both power-on and reset functions on the powder compacting machine 100, while simplifying operation.

[0071] As shown in Figures 1 and 12, the driving mechanism 6 includes a driving member 61, an output shaft 62 and a transmission assembly 7. The driving member 61 is mounted on the housing 1, and the output shaft 62 is mounted on the output end of the driving member 61. The first end of the transmission assembly 7 cooperates with the output shaft 62, and the second end of the transmission assembly 7 cooperates with the compressed powder shaft 23 of the compressed powder assembly 2; the transmission assembly 7 includes a driving wheel 71, a driven wheel 75, a first transmission wheel 72, a second transmission wheel 74 and a transmission shaft 73. The driving wheel 71 is mounted on the output shaft 62, the first transmission wheel 72 is mounted on the first end of the transmission shaft 73, the second transmission wheel 74 is mounted on the second end of the transmission shaft 73, the rotating shaft 73 is mounted on the housing 1 and rotates with the housing 1, and the driven wheel 75 is mounted outside the compressed powder shaft 23; wherein, the driving wheel 71 is meshed with the first transmission wheel 72, and the second transmission wheel 74 is meshed with the driven wheel 75. The driving member 61 is used to provide power for the driving mechanism 6 and drives the transmission assembly 7 through the output shaft 62. The transmission assembly 7 has a driving wheel 71, a first transmission wheel 72, a second transmission wheel 74 and a driven wheel 75, and transmits power through the transmission shaft 73 and the transmission wheel. By setting the driving wheel 71, the first transmission wheel 72, the second transmission wheel 74 and the driven wheel 75, the transmission ratio of the transmission assembly 7 and the output direction of the power are changed to meet the powder pressing requirements of the powder pressing machine 100.

[0072] The present invention also provides a method for resetting compressed powder of a powder pressing machine 100, comprising the following steps:

[0073] Step 1: Move the pushing member 33 to the first moving position, the reset member 32 is in the initial state, the pressing member 31 is abutted against the powder pressing assembly 2 through the reset member 32, and the powder pressing assembly 2 is in the reset state;

[0074] Step 2: Move the pushing member 33 from the first moving position to the second moving position. The pushing member 33 is used to resist the pressing member 31 and drive the pressing member 31 to move away from the powder pressing component 2. The reset member 32 is stretched by the pressing member 31, and the pressing member 31 is separated from the powder pressing component 2. The powder pressing component 2 is in an operating state.

[0075] This reset method is simple to operate. It only requires driving the push member 33 from the first moving position to the second moving position to achieve normal powder compacting operation of the powder compacting assembly 2. After the powder compacting is completed, the reaction force of the reset member 32 is used to accurately reset the powder compacting assembly 2, thereby avoiding interference when the powder compacting assembly 2 is reset, and improving the stability of the powder compacting machine 100.

[0076] As shown in Figures 2 to 4, the operating principle of this powder tamping machine 100 is as follows: First, the powder cup container 5 is inserted into the housing 1. The locking block 51 of the powder cup container 5 engages with the arc groove 19. The powder tamping groove 54 of the powder cup container 5 is located within the powder tamping chamber 11, and the powder tamping wheel 22 is located below the powder tamping groove 54. The locking block 51 of the powder cup container 5 screws into the locking groove 13, pushing the pusher 33 upward, thereby moving the pressing member 31 upward, and allowing the powder tamping assembly 2 to move upward. Then, coffee powder is transported into the powder tamping chamber 11 through the delivery pipe 12, and the microswitch 4 activates the drive mechanism 6, which drives the powder tamping assembly 2 to rotate. The powder tamping wheel 22 of the powder tamping assembly 2 grinds or stirs the coffee powder. As shown in Figure 4, as the amount of coffee powder in the powder tamping groove 54 increases, the powder tamping wheel 22 moves upward, pushing the powder tamping shaft 23 upward. When the coffee powder in the powder tamping groove 54 reaches a predetermined amount, the drive mechanism 6 stops. The powder cup container 5 is taken out of the powder compactor 100, and the clamping block 51 is separated from the clamping slot 13. The pushing member 33 is pushed to the first moving position by the pressing member 31 without the action of external force, and the powder compacting assembly 2 is also pressed to the reset state by the pressing member 31. The powder compacting assembly 2 is ready for the next powder compacting operation.
