Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specified otherwise.

In the description of the present invention, it should be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

In one embodiment, referring to fig. 1 to 4, a slag discharging mechanism includes: first casing 11, lifting unit 12 and actuating lever 13. The first housing 11 is configured to be mounted on the rotating base 30. The lifting assembly 12 includes a first motor 121, a first screw 122 and a first turbine 123. The first motor 121 is mounted on the first housing 11. The first worm wheel 123 is rotatably mounted on the first housing 11, and the first worm wheel 123 is sleeved outside the first screw 122. The first motor 121 is used for driving the first turbine 123 to rotate. Specifically, a first worm 124 is arranged between the first motor 121 and the first worm wheel 123, the first motor 121 drives the first worm 124 to rotate, and the first worm 124 drives the first worm wheel 123 to rotate. The driving rod 13 is connected with the first screw 122, the first screw 122 is used for driving the driving rod 13 to move up and down, and the driving rod 13 is used for being connected with the powder receiving head 21 in the brewing cavity 20. In particular, the driving rod 13 extends through the bottom wall of the chamber 25 of the brewing chamber 20 and is connected to the powder receiving head 21 in the brewing chamber 20.

In the residue discharge mechanism, when the first motor 121 works, the first motor 121 drives the first turbine 123 to rotate, the first turbine 123 drives the first screw 122 to move, the first screw 122 drives the driving rod 13 to move, and the driving rod 13 drives the powder receiving head 21 to move when moving along the cavity 25 of the brewing cavity 20, for example, when powder filling operation needs to be performed in the cavity 25 of the brewing cavity 20, the driving rod 13 drives the powder receiving head 21 to move to the bottom of the cavity 25 of the brewing cavity 20; for another example, after the coffee powder pressing and extracting operation step, when coffee grounds on the powder receiving head 21 in the cavity 25 of the brewing cavity 20 need to be discharged, the driving rod 13 drives the powder receiving head 21 to move to the feeding hole of the cavity 25 of the brewing cavity 20, so that the driving rod can conveniently act on the powder receiving head 21 to discharge the coffee grounds on the powder receiving head 21 outwards, and a better slag discharging effect can be realized. Therefore, on one hand, the structure of the slag discharging mechanism is simpler; on the other hand, in the deslagging process, positive thrust parallel to the axial direction of the brewing cavity 20 can be provided, so that the operation is more reliable, and a better deslagging effect can be realized.

Further, referring to fig. 4, the slag discharging mechanism further includes a guide plate 14. The guide plate 14 is fixedly arranged on the first housing 11, and the guide plate 14 is provided with a guide block 141. The outer side wall of the first screw 122 is further provided with a guide groove 1221, and the guide groove 1221 extends in the axial direction of the first screw 122. The guide block 141 is inserted into the guide groove 1221 and can move along the guide groove 1221. Therefore, in the process that the first worm wheel 123 drives the first screw 122 to move up and down in a rotating manner, since the guide block 141 of the first guide plate 14 extends into the guide groove 1221 on the outer side wall of the first screw 122, the guide block 141 moves along the guide groove 1221, so that the screw is ensured to move along the axis direction thereof, and the moving effect is relatively stable. The screw rod drives the driving rod 13 to move along the cavity 25 of the brewing cavity 20 synchronously in the process of moving along the axis direction of the screw rod, so that the movement direction of the driving rod 13 can coincide with the axis of the brewing cavity 20, namely, the powder receiving head 21 is driven by positive thrust coinciding with the axis, the generation of eccentric force in the pushing and pressing process can be avoided, and the smoothness and the reliability of the mechanism operation are ensured.

It should be explained that, because the positive thrust is adopted to push the powder collecting head 21, the strength of the deslagging mechanism can bear larger pressure, the structure of the deslagging mechanism is not easy to bend and deform, and the defects that the brewing cavity 20 leaks, the movement mechanism cannot be reset smoothly, the deslagging mechanism is easy to block and the like are avoided. In addition, the linkage relation is less, the movement is too complex, the component force generated in the movement process is small, the positive thrust attenuation is reduced, the locking is not easy to occur in the movement process, and the movement is smooth and reliable.

Further, referring to fig. 3 and 4, the number of the guide grooves 1221 is two or more, the number of the guide blocks 141 is two or more, and the two or more guide blocks 141 and the two or more guide grooves 1221 are disposed in a one-to-one correspondence manner. Specifically, the two guide grooves 1221 and the two guide blocks 141 are provided, and the two guide grooves 1221 are provided on opposite sides of the outer wall of the first screw 122. Of course, the number of the guiding grooves 1221 and the guiding blocks 141 may be other, such as one, three or other, and is not limited herein.

Further, referring to fig. 3, the guide plate 14 is provided with a through hole 142 corresponding to the first screw 122, the first screw 122 is sleeved in the through hole 142, and the guide block 141 is disposed on a hole wall of the through hole 142.

Further, referring to fig. 3 and 4, the slag discharging mechanism further includes a stop rib 15 disposed in the guide groove 1221. The bottom end of the first screw 122 is connected to the driving rod 13, the stopping rib 15 is disposed at the top end of the first screw 122, and the stopping rib 15 is used for abutting against and matching with the guide block 141. In this way, the stop rib 15 is disposed at the top end of the first screw 122, when the first screw 122 drives the driving rod 13 to move to the limit position, the stop rib 15 abuts against the guide block 141 of the guide plate 14, and the guide block 141 limits the first screw 122 to continue moving downward, thereby playing a stop role. In addition, since the stopper rib 15 is provided in the guide groove 1221 of the first screw 122, and does not protrude to the outside of the first screw 122, the occupied space is small, that is, the stopper function can be realized with a limited space, while the operational reliability is ensured. In one embodiment, the distance from the surface of the stop rib 15 away from the axial center of the first screw 122 to the axial center of the first screw 122 is not greater than the radius of the first screw 122. Thus, the stop rib 15 does not protrude out of the side wall of the first screw 122, and thus does not occupy additional space.

Further, referring to fig. 3 and 4, the slag discharging mechanism further includes a second locking sleeve 18 sleeved on the first screw 122. The second locking sleeve 18 is connected to the stop rib 15. Specifically, the second locking collar 18 and the stopper rib 15 are integrally formed. In addition, the second locking sleeve 18 is fixedly mounted on the first screw 122 by the first mounting member 19. A first mounting hole 1222 is formed on the top end wall surface of the first screw 122, and the first mounting member 19 passes through the first mounting hole 1222 to fasten the second locking sleeve 18 to the first screw 122. The first mounting member 19 is, for example, a screw, bolt, pin, rivet or other mounting member, and the first mounting hole 1222 is a mounting hole corresponding to the first mounting member 19.

In one embodiment, referring to fig. 3 and 4 again, there are two stopping ribs 15, two guiding grooves 1221, and the two stopping ribs 15 are correspondingly disposed in the two guiding grooves 1221 one to one. Therefore, the two stop ribs 15 are abutted against the two guide blocks 141 for limiting the guide plate 14, so that the moving assembly is well limited.

Further, referring to fig. 3 and 4, the inner wall of the first bearing sleeve 171 is provided with a thread matching with the thread of the first screw 122. Therefore, the pulling force and the shearing force applied by the first hook 16 to the first screw 122 are borne by the matched multiple circles of large-area threads of the two parts, and the orientation is realized by the locking piece, so that the tensile strength and the shearing strength of the connecting part of the first hook 16 and the first screw 122 are ensured, and the service life is greatly prolonged.

Further, referring to fig. 3 and 4, the first locking member 172 is a first locking sleeve. The first locking sleeve is sleeved outside the first screw 122, and the first locking sleeve is fixedly connected with the first bearing sleeve 171. The inner wall of the first locking sleeve is provided with a limiting rib 1721, and the limiting rib 1721 is arranged in the guide groove 1221. Thus, on the one hand, the first locking sleeve is fixedly connected to the first bearing sleeve 171; on the other hand, the first locking sleeve is arranged in the guide groove 1221 through the limiting rib 1721 of the first locking sleeve to be positioned with the first screw 122, so that the first locking piece 172, the first screw 122 and the first hook 16 can be stably combined together, the first locking piece 172, the first screw 122 and the first hook 16 can be assembled and fixed quickly, and the operation is convenient.

Therefore, the first locking sleeve can be stably installed on the first bearing sleeve 171, and the first locking sleeve and the first bearing sleeve are stably combined.

In one embodiment, the first locking sleeve is fixedly attached to the first bearing sleeve 171 by a plurality of second mounting members. Of course, the first locking sleeve can be fixedly connected to the first bearing sleeve 171 by other means, such as bonding or welding, without limitation.

Furthermore, a second mounting hole corresponding to the second mounting piece is formed in one end wall surface of the first locking sleeve. The second mounting hole extends from one end wall surface of the first locking sleeve to the other end wall surface of the first locking sleeve along the axial direction of the first locking sleeve, a third mounting hole corresponding to the second mounting hole is formed in the wall surface of the first bearing sleeve 171, and the second mounting piece penetrates through the second mounting hole and the third mounting hole to fasten the first locking sleeve on the first bearing sleeve 171.

In one embodiment, referring to fig. 3 and 4 again, the first bearing sleeve 171 and the first locking sleeve are disposed at the bottom end of the first screw 122.

In one embodiment, the outer wall of the first load bearing sleeve 171 is square, triangular, polygonal, circular, or oval in shape. The outer wall of the first locking sleeve is also square, triangular, polygonal, circular or elliptical in shape.

In one embodiment, referring again to fig. 1 and 2, a brewing apparatus includes: the residue discharge mechanism of any of the above embodiments further comprises a rotating seat 30 and a brewing chamber 20. The first housing 11 is mounted on the rotating base 30, and the driving rod 13, for example, penetrates through the bottom wall of the cavity 25 of the brewing cavity 20 and then is connected to the powder receiving head 21 in the brewing cavity 20.

In the brewing apparatus, when the first motor 121 works, the first motor 121 drives the first turbine 123 to rotate, the first turbine 123 drives the first screw 122 to move, the first screw 122 drives the driving rod 13 to move, and the driving rod 13 drives the powder receiving head 21 to move when moving along the cavity 25 of the brewing cavity 20, for example, when powder loading operation needs to be performed in the cavity 25 of the brewing cavity 20, the driving rod 13 drives the powder receiving head 21 to move to the bottom of the cavity 25 of the brewing cavity 20; for another example, after the coffee powder pressing and extracting operation step, when coffee grounds on the powder receiving head 21 in the cavity 25 of the brewing cavity 20 need to be discharged, the driving rod 13 drives the powder receiving head 21 to move to the feeding hole of the cavity 25 of the brewing cavity 20, so that the driving rod can conveniently act on the powder receiving head 21 to discharge the coffee grounds on the powder receiving head 21 outwards, and a better slag discharging effect can be realized. Therefore, on one hand, the structure of the slag discharging mechanism is simpler; on the other hand, during the deslagging process, positive thrust parallel to the axial direction of the brewing cavity 20 can be provided, so that the operation is reliable, and a good deslagging effect can be realized.

Further, referring to fig. 2, 5 and 6, a groove 31 extending from the top surface of the rotating base 30 to the bottom surface of the rotating base 30 is formed on the rotating base 30. The front surface of the rotating seat 30 is provided with a notch communicated with the groove 31, and the groove 31 comprises a first groove 311.

So, make chamber 20 detachably and install in first recess 311, actuating lever 13 can dismantle with the first screw rod 122 of lifting unit 12 and be connected, need carry out relevant maintenance to making chamber 20 like this, can dismantle in the lump with making chamber 20 and take actuating lever 13 to get off to relevant maintenance operation can, it is comparatively convenient to operate.

Further, referring to fig. 2, fig. 5 and fig. 6, the recess 31 further includes a second recess 312 communicated with the first recess 311, and the driving rod 13 is disposed in the second recess 312. Thus, in one of the operating states, for example, the driving rod 13 drives the powder receiving head 21 to move to the top of the brewing chamber 20 for deslagging, and the driving rod 13 moves into the brewing chamber 20 at this time, does not protrude out of the second groove 312, i.e., is disposed in the rotating seat 30, and is not exposed, occupies a small space, is protected by the rotating seat 30, is not easy to be damaged, and is convenient to transport. When the brewing cavity 20 needs to receive materials, the driving rod 13 correspondingly drives the powder receiving head 21 to move to the bottom of the brewing cavity 20, at this time, the driving rod 13 moves out of the brewing cavity 20 and extends out of the second groove 312, the second groove 312 does not limit the up-and-down movement of the driving rod 13, and the driving rod 13 can freely move up and down in the second groove 312.

Further, referring to fig. 2, 5 and 6, the opening size of the first recess 311 is larger than that of the second recess 312, a second step 32 is formed at a position adjacent to the first recess 311 and the second recess 312, and the brewing cavity 20 is abutted against the second step 32. Thus, on the one hand, the brewing chamber 20 can be stably mounted on the rotating seat 30; on the other hand, the external dimension of the brewing cavity 20 and the external dimension of the driving rod 13 are matched with the shape dimension of the groove 31, so that the brewing cavity 20 and the rotating seat 30 are compact in structure, and the brewing device is small in volume.

Further, referring to fig. 2, 5 and 6, a notch 313 is formed on a wall of the first groove 311, a protruding rib 22 corresponding to the notch 313 is formed on an outer wall of the brewing chamber 20, and the protruding rib 22 is disposed in the notch 313. Thus, when the brewing chamber 20 is installed in the first groove 311 of the rotating base 30, the protruding ribs 22 are correspondingly and synchronously installed in the notches 313 at the groove walls, so that the brewing chamber 20 is stably installed in the first groove 311, and the brewing chamber 20 is prevented from shaking in the rotating base 30, i.e. the brewing chamber 20 has better stability on the rotating base 30. In particular, the notch 313 is arranged around the wall of the groove 311, the mouth wall of the notch 313 being arranged parallel to the second step 32, so that, during the insertion of the brewing chamber 20 into the groove 31 through the mouth of the groove 31, the bottom wall of the brewing chamber 20 moves along the second step 32, the protruding ridges 22 being synchronously aligned with the notch 313 and inserted into the notch 313.
