In one embodiment, referring to fig. 1 and 2, a rack includes a rack body 11 and a guide rail 12. The frame 11 is provided with a pushing mechanism 20. The guide rail 12 is arranged on the frame body 11, and the guide rail 12 is used for being in sliding fit with a hanging table 31 on the outer wall of the brewing cavity 30. Referring to fig. 6 to 11, fig. 6 to 11 are diagrams illustrating an initial powder receiving state, a state of the brewing chamber 30 rotating relative to the frame 11 and abutting against the pressing mechanism 20, and a state of powder pressing extraction of the brewing apparatus according to an embodiment. In the process of switching the powder receiving position and the powder pressing position of the brewing chamber 30, the hanging table 31 slides along the guide rail 12 and is always carried above the guide rail 12.

Above-mentioned frame, owing to be equipped with on support body 11 with the guide rail 12 that makes the platform 31 sliding fit on the outer wall of chamber 30, make the chamber 30 like this and connect powder position and the mutual switching-over in-process of powder position, hang the platform 31 and slide along guide rail 12, and carry on all the time guide rail 12 top to can improve the butt joint reliability, can realize making the counterpoint in the axial direction of the port 32 of chamber 30 and the brewing head 23 of pushing and pressing mechanism 20, counterpoint the accuracy, the butt joint effect is better.

Further, referring to fig. 2 to 5, the frame 11 includes a support plate 111. The plate surface of the support plate 111 is adapted to be in sliding contact with the back surface 44 of the rotatable base 40. The guide rail 12 is disposed on the support plate 111, a bottom surface of the guide rail 12 is used for being in sliding contact with a top surface of the rotating seat 40, and a top surface of the guide rail 12 is used for being in sliding contact with the hanging table 31. When the rotary base 40 rotates relative to the frame body 11, the back surface 44 of the rotary base 40 slides relative to the plate surface of the support plate 111, and the top surface of the rotary base 40 slides along the bottom surface of the guide rail 12, so that the rotary effect of the rotary base 40 is stable. In addition, the brewing cavity 30 rotates synchronously along with the rotating seat 40, the hanging table 31 slides along the top surface of the guide rail 12, the stability is good, the butt joint reliability can be improved, the alignment of the port 32 of the brewing cavity 30 and the brewing head 23 of the pushing and pressing mechanism 20 in the axial direction can be realized, the alignment is accurate, and the butt joint effect is good.

In one embodiment, referring to fig. 1 and 2 again, a brewing apparatus includes the frame of any of the above embodiments, and further includes a pressing mechanism 20, a brewing chamber 30 and a rotating base 40. The pushing mechanism 20 is mounted on the frame 11, and the rotating base 40 is rotatably mounted on the frame 11. The brewing cavity 30 is arranged on the rotating seat 40, a hanging table 31 is arranged on the outer wall of the brewing cavity 30, and the hanging table 31 is slidably arranged on the guide rail 12.

Above-mentioned brewing device, owing to install on support body 11 and be equipped with the guide rail 12 with the platform 31 sliding fit that hangs on the outer wall of making a brew chamber 30, make a brew chamber 30 like this and connect powder position and the mutual switching-over in-process of powder position, hang the platform 31 and slide along guide rail 12, and carry on all the time guide rail 12 top to can improve the butt joint reliability, can realize making a brew chamber 30's port 32 and pushing and pressing mechanism 20 dash the bubble head 23 counterpoint in the axial direction, counterpoint accurate, butt joint effect is better.

Further, referring to fig. 2 and 8, the pressing mechanism 20 includes a housing 21, a first screw 22, a brewing head 23, a first turbine 24, and a first motor 25. The housing 21 is mounted on the frame 11. The brewing head 23 is mounted at one end of the first screw 22. The first worm wheel 24 is rotatably mounted on the housing 21, the first worm wheel 24 is sleeved outside the first screw 22, and the first motor 25 is used for driving the first worm wheel 24 to rotate. Thus, when the first motor 25 works, the first motor 25 drives the first turbine 24 to rotate on the shell 21, the first turbine 24 drives the first screw 22 to move when rotating, and the first screw 22 drives the brewing head 23 at the end to move and extend into the brewing chamber 30 so as to press and extract coffee powder.

Further, referring to fig. 2 and 8, the pressing mechanism 20 further includes a sliding block 26 disposed at the other end of the first screw 22. The housing 21 is provided with a sliding channel 211, and the sliding block 26 is movably disposed in the sliding channel 211. When the pushing mechanism 20 works, the first motor 25 drives the first worm wheel 24 to rotate, the first worm wheel 24 drives the first screw 22 to rotate, and the sliding block 26 on the first screw 22 slides along the sliding channel 211, so that the first screw 22 moves along the sliding channel 211. The first screw 22 drives the brew head 23 to move during the movement along the sliding channel 211, so that the brew head 23 can press coffee powder. Compared with the traditional pushing and pressing mode, the brewing head 23 in the application has the advantages that under the guiding and balancing action of the sliding block 26, the movement direction of the brewing head 23 coincides with the axis of the brewing cavity 30, namely, the powder is pressed by positive pushing force coinciding with the axis, the eccentric force generated in the pushing and pressing process can be avoided, and the smoothness and the reliability of the mechanism operation are guaranteed.

It should be explained that, because the positive thrust powder pressing is adopted, the strength of the pushing mechanism 20 can bear the huge pressure generated during brewing, and the structure is not easy to bend and deform during brewing, so that the defects of leakage of the brewing cavity 30, incapability of successfully resetting the moving mechanism, easiness in blocking 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.

Specifically, referring to fig. 8, a first worm 27 is connected to a rotating shaft of the first motor 25. The first worm 27 is in driving connection with the first worm wheel 24. The rotating shaft of the first motor 25 drives the first worm 27 to rotate, and the first worm 27 correspondingly drives the first worm wheel 24 to rotate.

Further, referring to fig. 8, the pressing mechanism 20 further includes a guide plate 28 fixedly disposed on the housing 21. The guide plate 28 is provided with a guide block 281. The outer wall of the first screw 22 is provided with a guide groove (not shown) in the axial direction thereof, and the guide block 281 is movably disposed in the guide groove. In this way, when the first worm wheel 24 drives the first screw 22 to move, the guide block 281 guides the first screw 22 through the guide groove, so that the first screw 22 can move along the axial direction of the brewing chamber 30, and the moving effect is relatively smooth.

Further, the number of the guide grooves is two or more, the number of the guide blocks 281 is two or more, and the two or more guide blocks 281 and the two or more guide grooves are arranged in one-to-one correspondence. Specifically, two guide grooves and two guide blocks 281 are provided at opposite sides of the outer wall of the first screw 22. Of course, the number of the guiding slots and guiding blocks 281 may be other, such as one, three or other, and is not limited herein.

Further, referring to fig. 8, the guide plate 28 is provided with a through hole 282 corresponding to the first screw 22, the first screw 22 is sleeved in the through hole 282, and the guide block 281 is disposed on a hole wall of the through hole 282.

In one embodiment, referring to fig. 8, when the first screw 22 drives the brewing head 23 to move to the limit position, the sliding block interferes with the guiding plate 28 to limit the first screw 22 to move continuously, so as to achieve the stopping function.

In another embodiment, the biasing mechanism 20 further includes a stop rib. The stop rib is fixedly arranged at one end of the guide groove far away from the brewing head 23, and the stop rib is used for being in interference fit with the guide block 281. Thus, the stop rib is disposed at one end of the guide slot close to the slide block 26, when the first screw 22 drives the brewing head 23 to move to the limit position, the stop rib contacts with the guide block 281 of the guide plate 28, and the guide block 281 restricts the first screw 22 to move continuously, thereby playing a stop role. In addition, because the locking rib is arranged in the guide groove of the rod body and does not protrude outside the first screw rod 22, the occupied space is small, namely, the locking function can be realized under the condition of limited space, and the operation reliability is ensured. In one embodiment, the distance from the surface of the stop rib away from the axial center of the first screw 22 to the axial center of the first screw 22 is not greater than the radius of the first screw 22. In this way, the stop rib does not protrude beyond the side wall of the first screw 22, and thus does not occupy additional space.

In one embodiment, the number of the stop ribs is two, the number of the guide grooves is two, and the two stop ribs are arranged in the two guide grooves in a one-to-one correspondence manner. Thus, the two stop ribs abut against the two guide blocks 281 of the limiting guide plate 28, so that the moving assembly is well limited.

Further, referring to fig. 6 and 9, the brewing apparatus further includes a rail-changing mechanism 50. The track transfer mechanism 50 is connected to the first screw 22. The track transfer mechanism 50 is provided with a first track 51 and a second track 52 which are communicated with each other. The first rail 51 is provided along the axial direction of the first screw 22, and the second rail 52 is provided obliquely with respect to the first rail 51. A sliding part 41 is arranged on the rotating seat 40, and the sliding part 41 is slidably arranged on the first rail 51 or the second rail 52.

Thus, when the brewing chamber 30 is in the dusting position (in which the port 32 of the brewing chamber 30 is, for example, horizontal), the slide 41 is located at the end of the second rail 52 remote from the first rail 51. When the brewing chamber 30 on the rotary seat 40 needs to be switched from the powder receiving position to the powder pressing position (when the brewing chamber 30 is in the powder pressing position, the port 32 of the brewing chamber 30 needs to be aligned with the brewing head 23 of the pushing mechanism 20, and at this time, the axis direction of the brewing chamber 30 is inclined relative to the horizontal direction, for example), the pushing mechanism 20 acts to move the sliding member 41 onto the first rail 51 along the second rail 52, and the sliding member 41 drives the rotary seat 40 and the brewing chamber 30 to synchronously rotate, so that the brewing chamber 30 and the rotary seat 40 rotate to the powder pressing position.

When the powder pressing operation is required, the first screw 22 continuously moves, the rail changing mechanism 50 is synchronously driven to move, the sliding part 41 moves along the first rail 51, the first rail 51 and the first screw 22 move in the same direction, the first screw 22 does not drive the rotating seat 40 and the brewing cavity 30 to rotate when moving, and the brewing head 23 extends into the brewing cavity 30 and presses and extracts coffee in the brewing cavity 30. That is, when the first motor 25 drives the first screw 22 to move, on one hand, under the synchronous action of the track-changing mechanism 50, the rotary seat 40 and the brewing cavity 30 can be switched between the powder receiving position and the powder pressing position; on the other hand, when the rotary seat 40 and the brewing chamber 30 are in the powder pressing position, the first motor 25 drives the first screw 22 to continue to operate, so that the brewing head 23 extends into the brewing chamber 30 and presses and extracts coffee in the brewing chamber 30. Thus, the position conversion of the rotating seat 40 and the brewing cavity 30 and the powder pressing action of the brewing head 23 can be realized by only adopting one first motor 25, so that the device has simple structure and low cost.

Further, referring to fig. 1 and 2, the frame 11 includes a support plate 111. The plate surface of the support plate 111 and the back surface 44 of the rotating base 40 are in rotatable contact with each other. The supporting plate 111 is provided with an arc-shaped hole 112, the sliding member 41 is installed on the back 44 of the rotating base 40, the sliding member 41 can move along the arc-shaped hole 112, and the sliding member 41 can be movably arranged on the track-changing mechanism 50 after passing through the arc-shaped hole 112. Thus, when the pushing mechanism 20 is actuated to move the sliding member 41 along the second rail 52, the sliding member 41 synchronously moves along the arc-shaped hole 112 on the supporting plate 111, and synchronously drives the rotating base 40 to rotate relative to the frame body 11, so as to switch the brewing chamber 30 from the powder receiving position to the powder pressing position. In addition, the rotary seat 40 has stable operation effect. It is understood that the second rail 52 is an arc-shaped rail disposed corresponding to the arc-shaped hole 112, or the second rail 52 is a bar-shaped movable opening capable of corresponding to completely covering the arc-shaped hole 112, and the movable opening is disposed obliquely with respect to the first rail 51.

Further, referring to fig. 3, 4 and 6, the sliding member 41 is a rotating plate capable of moving along the arc-shaped hole 112. Alternatively, the sliding member 41 is one or more first transmission columns movable along the arc-shaped hole 112. Therefore, when the sliding part 41 moves along the arc-shaped hole 112, the rotating seat 40 is driven to move, and the moving effect is stable. Specifically, the sliding member 41 may be one first transmission column, or may be two or more first transmission columns, and when the two or more first transmission columns are arranged in parallel, the formed structure is similar to an arc-shaped rotating plate.

Further, referring to fig. 3, fig. 4 and fig. 6, the first rail 51 and the second rail 52 are first openings disposed on the rail transferring mechanism 50, an anti-dropping element 53 moving along the first openings is disposed on the rail transferring mechanism 50, and the anti-dropping element 53 is detachably connected to the sliding element 41. Thus, in the process of installing the rotating seat 40 on the track transfer mechanism 50, after the sliding part 41 is installed in the first opening, the anti-drop part 53 is connected with the sliding part 41, so that the track transfer mechanism 50 can be conveniently assembled with the rotating seat 40. The escape preventing member 53 prevents the sliding member 41 from escaping from the first opening. Conversely, when the anti-drop piece 53 is removed, the sliding piece 41 can be separated from the track-changing mechanism 50, that is, the track-changing mechanism 50 can be removed from the rotating seat 40. Specifically, the retaining member 53 is a retaining plate that is movable along the first rail 51 and the second rail 52 along with the slider 41.

Further, referring to fig. 3, 4 and 6, a rotating shaft hole 113 is further formed on the supporting plate 111, a rotating member 42 is disposed on the rotating seat 40, and the rotating member 42 is rotatably disposed in the rotating shaft hole 113. When the rotary base 40 is rotated with respect to the support plate 111 in this manner, the rotary base is rotated about the rotary member 42. Specifically, the rotating member 42 is a second transmission column.

Further, referring to fig. 3, 4 and 6, the rotation shaft hole 113 is located in the extending direction of the first track 51. So, drive through first screw rod 22 and dash the in-process that bubble head 23 stretched into in making the chamber 30, the positive thrust direction of the bubble head 23 of first screw rod 22 is through pivot hole 113, makes the chamber 30 and can not rotate, and stability is better, can guarantee better dust extraction effect. Of course, as an alternative, the rotation shaft hole 113 may be disposed at other positions on the support plate 111, and is not necessarily located in the extending direction of the first rail 51.

Further, referring to fig. 8, the sliding block 26 includes a bearing sleeve 261 sleeved outside the first screw 22, and a locking member 262 for fastening the bearing sleeve 261 to the first screw 22. In this way, the sliding block 26 not only can play a guiding role, but also the sliding block 26 is firmly arranged on the first screw 22, so that a large enough force is provided to drive the track-changing mechanism 50 to move. Specifically, the slider 26 is connected to the track switching mechanism 50.

Further, referring to fig. 8, the sliding block 26 further includes a first hook 263 connected to the bearing sleeve 261. The inner wall of the bearing sleeve 261 is provided with threads matched with the threads of the first screw 22. Thus, the first hook 263 can be used for hanging a heavy object, and the first hook 263 is specifically connected with the track-changing mechanism 50. The pulling force and the shearing force applied to the first screw 22 by the first hook 263 are borne by the two matched circles of large-area threads, and the orientation is realized by the locking piece 262, so that the tensile strength and the shearing strength of the connecting part of the first hook 263 and the first screw 22 are ensured, and the service life is greatly prolonged.

Further, referring to fig. 8, the locking member 262 is a locking sleeve, the locking sleeve is sleeved outside the first screw 22, and the locking sleeve is fixedly connected to the bearing sleeve 261. The inner wall of locking collar is equipped with spacing muscle 2621, be equipped with the guide way on the outer wall of first screw rod 22 along its axial direction, spacing muscle 2621 set up in the guide way. Thus, on the one hand, the locking sleeve is fixedly connected to the bearing sleeve 261; on the other hand, the locking cover is located through its spacing muscle 2621 and is realized realizing mutually fixing a position with first screw rod 22 in the guide way, just so can realize that locking piece 262, first screw rod 22 and first couple 263 three combine together firmly, and the three can realize that fast assembly is fixed, and it is comparatively convenient to operate.
