Referring to fig. 1 to 9, the present application provides a powder conditioning system. In one embodiment, the powder conditioning system comprises a base 1 and a powder delivery device comprising a hopper 4 and a drive mechanism 5 for delivering powder between a powder collecting position and a powder compacting position. The base body 1 has a pressing portion 2. The respective components included in the powder conditioning system are described in detail below.

Referring to fig. 1 to 3, the pressing portion 2 is fixed on the base 1, and is used for compacting powder 47 into a cake in cooperation with the aggregate cylinder 4, and is also used for passing liquid through the cake to brew the cake to prepare a beverage. The pressurizing part 2 is provided with a pressurizing part shell 21, an upper filter screen 22 and a drinking pipeline 23. The upper screen 22 is mounted on the lower end surface of the pressing part housing 21, and the drinking water outlet pipe 23 is provided inside the pressing part housing 21. The outlet pipe 23 is connected to the upper and lower ends of the pressurization part housing 21, the lower port of the outlet pipe 23 is connected to the upper filter screen 22, the upper port of the outlet pipe 23 is a liquid outlet 230, and the liquid filtered by the upper filter screen 22 is discharged through the liquid outlet 230 of the outlet pipe 23.

With continued reference to fig. 1-3, the drive mechanism 5 is mounted on the base 1. The driving mechanism 5 includes a motor 51 and a rotating member driven by the motor 51. In the present embodiment, the rotating member is a screw 53, and in other embodiments, the rotating member may be provided as a cam, a link, or the like. In this embodiment, the drive mechanism 5 includes a motor 51, a drive gear set 52, and a screw 53. The motor 51 drives the screw 53 to rotate through the transmission gear set 52. In the present embodiment, the transmission gear set 52 includes a driving gear 521 connected to an output shaft of the motor 51 and a driven gear 522 connected to one end of the screw 53, the driving gear 521 and the driven gear 522 being engaged with each other. The motor 51 can output in forward and reverse directions, so that the screw 53 is driven to rotate in forward or reverse directions through the transmission gear set 52. The drive mechanism 5 further includes an upper bearing 54 mounted at the upper end of the screw 53 and a lower bearing 55 mounted at the lower end of the screw 53. The arrangement of the upper and lower bearings 54, 55 can make the rotation of the screw 53 smooth and steady. It should be noted that, the structure of the transmission gear set 52 is not limited to this, and in some embodiments, the transmission gear set 52 may also adopt a combination of gears with more stages to achieve functions of speed change, torque change, easy installation, etc.; in other embodiments, the drive gear set 52 may be omitted and the screw 53 directly driven to rotate by the output shaft of the motor 51.

With continued reference to fig. 1-3, the cartridge 4 is movably coupled to the screw 53 relative to the base 1. The material collection cylinder 4 is configured to be rotatable around a prescribed axis to transport the powder and movable along the prescribed axis to pressurize the powder; in the present embodiment, the predetermined axis is a rotation axis of the screw 53. The collecting barrel 4 comprises a barrel shell 41 and a powder pushing piece 44, wherein the barrel shell 41 is provided with a collecting cavity 410 for containing powder, and the powder pushing piece 44 is arranged in the collecting cavity 410 in a relatively movable mode. In this embodiment, the shell 41 has a cylindrical structure, at least the upper half of which is hollow to form an aggregate chamber 410 for containing the powder 47 and for inserting the pressurizing portion 2 to compact the powder 47. The powder pushing member 44 is piston-shaped and has a piston rod 441 and a piston head 442, and the piston rod 441 is connected to the lower portion of the piston head 442. The diameter of the piston head 442 is equal to the inner diameter of the collection chamber 410 to ensure that the two can move relative to each other while preventing the powder 47 from falling from the gap therebetween. The cartridge 41 has a bottom plate portion with an aperture for the piston rod 441 to pass through, which prevents the piston head 442 from falling out of the collection chamber 410. When the piston head 442 of the powder pushing member 44 abuts against the bottom plate, the upward movement of the cylinder housing 41 drives the powder pushing member 44 to move upward synchronously. The powder pushing member 44 may also move up and down in the collecting cavity 410 relative to the cylinder housing 41, where the powder pushing member 44 moves up relative to the cylinder housing 41, so that the powder cake may be ejected out of the collecting cavity 410, and the powder pushing member 44 moves down relative to the cylinder housing 41, so as to reset to the lower part of the cylinder housing 41. The powder pushing member 44 further includes an abutting portion 45, and the abutting portion 45 may cooperate with the limiting portion 12 and the guiding portion 13 on the base 1 to achieve a corresponding action. The process of the powder pushing member 44 being engaged with the base 1 by the abutting portion 45 will be described in detail later.

The cartridge housing 41 includes a screw sleeve 46 extending outwardly from the peripheral wall of the cylindrical structure, the screw sleeve 46 being received over the screw 53. The screw sleeve 46 is provided with an internal thread so as to be in transmission connection with an external thread on the screw rod 53, a certain static friction force is arranged between the screw sleeve 46 and the screw rod 53, the static friction force can enable the screw sleeve 46 and the screw rod 53 to synchronously move, and when the static friction force is overcome, relative movement can be generated between the screw sleeve 46 and the screw rod 53. Specifically, the matching relationship between the two is: when the cylinder shell 41 is not blocked, the rotation of the screw 53 drives the spiral sleeve 46 and the whole material collecting cylinder 4 to synchronously rotate along with the screw 53; when the cartridge 41 is blocked from rotating synchronously with the screw 53, rotation of the screw 53 moves the screw sleeve 46 and the entire cartridge 41 up or down on the screw 53. Thus, the left-right rotation and up-down movement of the cylinder housing 41 can be realized only by the rotation of the screw 53, so that a plurality of actions of powder receiving and powder pressing can be realized conveniently. The cylinder shell 41 is further provided with a water inlet 43, the water inlet 43 extends outwards from the circumferential side of the cylinder shell 41, the water inlet 43 is communicated to the lower portion of the piston head 442 of the powder pushing member 44, the piston head 442 is provided with a plurality of water holes, and the piston head 442 is further provided with a lower filter screen 42. The liquid entering from the water inlet 43 passes through the water holes on the piston head 442 and the lower filter screen 42, and is discharged through the upper filter screen 22 of the pressurizing part 2 and the liquid outlet 230 of the drinking pipeline 23 after soaking the compacted compact.

With continued reference to fig. 1-3, the base 1 is configured for mounting the pressing portion 2, the cartridge 4 and the drive mechanism 5. The base body 1 is provided with a rotation avoiding portion 101, one section of the screw 53 is exposed through the rotation avoiding portion 101, and the spiral sleeve 46 is located at the rotation avoiding portion 101 and connected to the screw 53. The powder sorting system is provided with a powder collecting position P1 for the powder material 47 received in the material collecting cylinder 4 and a powder pressing position P2 for the powder material 47 received in the material collecting cylinder 4 to be pressed, wherein the powder pressing position P2 is different from the powder collecting position P1, namely the powder pressing position P2 and the powder collecting position P1 are not the same. It should be noted that the positions in the powder collecting position P1 and the powder compacting position P2 should not be interpreted as limiting to a specific point, but should be interpreted as a station where a certain process can be performed, for example, in this embodiment, the powder compacting position P2 specifically further includes a powder compacting initial position and a powder compacting complete position, and the aggregate cylinder 4 is movable between the powder compacting initial position and the powder compacting complete position at the time of the powder compacting position P2. In this embodiment, the rotation avoidance portion 101 makes the cylinder housing 41 have a rotation space with a certain angle range, and the extreme positions of the two ends of the rotation of the cylinder housing 41 in the rotation avoidance portion 101 form the powder collecting position P1 and the powder pressing position P2. The base body 1 is further provided with a channel 102 communicated with the rotation avoiding portion 101, the channel 102 is communicated with a powder pressing position P2 formed by the rotation avoiding portion 101, and when the cylinder shell 41 rotates to the end of the rotation avoiding portion 101 and cannot continue to rotate, the cylinder shell is driven by the screw 53 to move upwards along the channel 102. When the screw sleeve 46 connected with the cartridge 41 is positioned in the channel 102, both the forward and the reverse rotation of the screw 53 can enable the two sides of the channel 102 to prevent the cartridge 41 from rotating along with the screw 53, so that the cartridge 41 is driven by the rotating movement of the screw 53 to move in an upward or downward translational movement, namely, the two sides of the channel 102 respectively form a first blocking position 11 and a second blocking position 14. The first blocking position 11 enables the cylinder shell 41 to be blocked from rotating and move upwards during the rotation process of the screw 53, and the second blocking position 14 enables the cylinder shell 41 to be blocked from rotating and move downwards during the rotation process of the screw 53. In other embodiments, the first blocking bit 11 and the second blocking bit 14 are not limited to being formed by edges on both sides of the channel 102, and may be configured as other structures or components.

Referring to fig. 1 to 3 and fig. 6 and 7, the base 1 is provided with a limiting portion 12 for limiting the movement of the powder pushing member 44 in a direction away from the pressing portion 2, and when the screw 53 drives the cylinder 41 to move downward, the powder pushing member 44 is fixed, so that the powder pushing member 44 pushes the powder 47 out of the cylinder 41 due to the relative movement of the two members, because the limiting portion 12 limits the movement of the powder pushing member 44. Further, the limiting portion 12 is configured to be elastically deformable, in this embodiment, the limiting portion 12 is an elastic arm provided with a stopper, the lower surface of the stopper is an inclined guiding surface, and the upper surface of the stopper is a horizontal supporting surface, so that the abutting portion 45 of the powder pushing member 44 can compress the limiting portion 12 to elastically deform and slide over the guiding surface of the stopper during the upward movement of the cylinder 4, and the abutting portion 45 abuts against the supporting surface to prevent the continuous downward movement of the cylinder shell 41 and the powder pushing member 44 during the downward movement of the cylinder 4. In other embodiments, the elastic deformation of the limiting portion 12 may also adopt a structure of matching a spring with a top block; in other embodiments, the abutting portion 45 on the powder pushing member 44 may be configured to be elastically deformable, and the limiting portion 12 on the base 1 may be configured to be not elastically deformable. In short, the cooperation between the limiting portion 12 and the abutting portion 45 may be such that both may pass through the push-up member 44 when moving up and may be blocked when moving down.

The base 1 is further provided with a guide portion 13, and the guide portion 13 is configured to guide the powder pushing member 44 to move away from the pressing portion 2. In this embodiment, the guiding portion 13 is a guiding rib extending obliquely from top to bottom, and the upper end of the guiding rib is higher than the limiting portion 12, i.e. the upper end of the guiding rib is located above the limiting portion 12, and a space is provided between the two, so that the abutting portion 45 of the powder pushing member 44 can be separated from the limiting portion 12 and moved to the lower portion of the guiding portion 13. In this embodiment, the base body 1 is provided with a cylindrical surface, and the guide portion 13 is provided as a spiral rib extending along the cylindrical surface. The guide portion 13 may also be provided in a guide groove structure. The guiding portion 13 may guide the powder pushing member 44 to be reset to the initial position in the material collecting cavity 410 after being separated from the limiting portion 12, so as to perform the next actions of powder receiving, transferring, powder pressing, etc. In an embodiment, the guide portion 13 may be omitted, and the powder pushing member 44 is reset under the action of gravity by the self weight of the powder pushing member 44 or the added weight structure; in other embodiments, the elastic restoring member such as a spring may be provided to apply a force to the powder pushing member 44 so as to restore the powder pushing member 44.

Referring to fig. 1, 2, 8 and 9, the base 1 is further provided with a scraping portion 3, and the scraping portion 3 is configured to push the powder 47 exposed out of the shell 41 by the powder pushing member 44 to be pushed by the scraping portion 3 to fall off from the powder pushing member 44 when the shell 41 moves from the powder pressing position P2 to the powder collecting position P1, so as to realize automatic discharging and collecting of the powder cake after brewing, and the powder cake after brewing may also be referred to as powder slag. In this embodiment, the scraping portion 3 is in a semicircular arc shape, which is similar to the half contour of the powder cake, so that the slag pushing action is more reliable. The powder collecting position P1 is further provided with a detector for detecting whether the material collecting barrel 4 is positioned at the powder collecting position P1, and in this embodiment, the detector is a position switch 15 fixed on the base 1 and is used for controlling the movement of the material collecting barrel 4 in place.

Wherein the driving mechanism 5 can drive the material collecting cylinder 4 to move from the powder collecting position P1 to the powder pressing position P2; the charging barrel 4 can be driven to move from a powder pressing initial position to a powder pressing completion position when in a powder pressing position P2, namely, the charging barrel 4 is driven to move towards the pressurizing part 2 so as to compact powder 47 into the charging cavity 410; the powder collecting cylinder 4 can be driven to move from the powder pressing completion position to the powder pressing initial position when in the powder pressing position P2, namely, the cylinder shell 41 is driven to move away from the pressurizing part 2 relative to the powder pushing piece 44 so as to push the powder 47 out of the powder collecting cavity 410; and, the charging barrel 4 can be driven to reset from the powder pressing position P2 to the powder collecting position P1. Here, the direction in which the hopper 4 moves from the powder collecting position P1 to the powder compacting position P2 is referred to as a first direction; the direction in which the cylinder 4 moves toward the pressing portion 2 at the powder pressing position P2 is referred to as a second direction; the direction in which the cartridge case 41 moves away from the pressing portion 2 after the completion of the pressing at the pressing position P2 is referred to as a third direction; the direction in which the cartridge case 41 moves from the powder compacting position P2 to the powder collecting position P1 is referred to as a fourth direction. The first direction and the fourth direction are opposite directions, the second direction and the third direction are opposite directions, the first direction and the fourth direction are rotation moving directions in a horizontal plane, and the second direction and the third direction are up-and-down moving directions in a vertical plane. The screw 53 drives the cartridge 4 to move in the first direction and the second direction in sequence in one rotational direction, as indicated by the arrow R1 in fig. 1. The screw 53 rotates synchronously with the material collecting barrel 4 to drive the material collecting barrel 4 to move along the first direction, and the screw 53 moves relative to the material collecting barrel 4 to drive the material collecting barrel 4 to move along the second direction. The screw 53, when rotated in the opposite direction to the direction indicated by the arrow R1 in fig. 1, drives the cartridge 41 to move in the third and fourth directions in succession. The screw 53 moves relative to the cartridge housing 41 to drive the cartridge 4 to move in the third direction, and the screw 53 rotates in synchronism with the cartridge housing 41 to drive the cartridge 4 to move in the fourth direction.
