Description

Technical Field

[0001] This disclosure relates to the field of coffee roaster technology, and in particular to a coffee bean roasting mechanism and a coffee roaster. Background Technology

[0002] In recent years, coffee has become an indispensable part of modern people's daily lives. Coffee is made by grinding coffee beans and then brewing them. However, to ensure that the coffee beans release their aroma, they need to undergo a roasting process before grinding, such as light roast or dark roast. Current coffee roasters on the market generally place the coffee beans into a roasting drum, where a heating element roasts them. Simultaneously, the roasting drum is driven by a motor to rotate, ensuring that each coffee bean is roasted evenly. However, after roasting, the drum needs to be rotated or tilted at a certain angle to unload the roasted coffee beans, which is somewhat inconvenient.

[0003] Therefore, the existing patent CN211324504U discloses a home coffee bean roaster, which includes a base module, a bean feeding module, a roasting module and a bean dispensing module. The bean dispensing module includes a bean dispensing door and a bean dispensing door mechanism that is linked to the bean dispensing door. The bean valve mechanism can drive the bean dispensing door to switch between a closed state and an open state. In the closed state, the bean dispensing door closes the bean outlet. In the open state, the bean dispensing door opens the bean outlet, so that the coffee beans can leave the roasting chamber from the bean outlet along the inclined plate. Thus, after roasting, the bean dispensing mechanism is operated to drive the bean dispensing door into the open state, releasing the bean outlet. In one embodiment, the bean dispensing module includes a bean dispensing door mechanism, a bean dispensing door, a spring, a bean collection box, a bean dispensing channel, and a side shell. When it is necessary to open the bean dispensing door, the user can apply force to the connecting rod of the bean dispensing door mechanism, causing the pressing section of the connecting rod to pivot downward and the abutting section of the connecting rod to pivot upward, so that the abutting post moves along the movable groove from the position abutting the free end of the bean dispensing door to the position abutting the pivot end of the bean dispensing door, and the bean dispensing door is switched to the open state.

[0004] However, when opening the bean outlet, the user needs to continuously apply force and press the lever to ensure that the bean outlet is open. If the coffee beans in the coffee roaster have not all entered the bean collection box, the bean outlet door will close if the user accidentally releases the lever, making the operation more laborious and unable to achieve the effect of keeping the bean outlet open when the user releases the force. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a coffee bean roasting mechanism and coffee roaster that can keep the chamber door open when adjusted to a certain position and keep the chamber door closed when adjusted to another position.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A coffee bean roasting mechanism includes a mounting plate, a middle plate, a roasting assembly, a bean outlet pipe, a bean receiving assembly, and a hopper door opening and closing control assembly. The middle plate is connected to the mounting plate and has a bean outlet and a bean receiving outlet. The roasting assembly, the bean receiving assembly, and the bean outlet pipe are all connected to the middle plate, and the bean outlet pipe is also connected to the mounting plate. The roasting assembly has a roasting cavity that communicates with the bean outlet. The bean outlet pipe communicates with the bean receiving outlet and has a control through-hole. The bean outlet pipe is disposed on the mounting plate. The bean receiving assembly has a bean receiving cavity that communicates with the bean receiving outlet. The hopper door opening and closing control assembly... The control assembly includes a door rotation switch component, a sliding member, a bean dispensing door, a spring, and a spring fixing member. The sliding member is movably mounted on the bean dispensing pipe, and the bean dispensing door is located inside the bean dispensing pipe. The end of the bean dispensing door also passes through the control through hole and is fixedly connected to the sliding member. The spring fixing member has a receiving groove, and the two ends of the spring abut against the spring fixing member and the sliding member respectively, and the spring is located in the receiving groove. The door rotation switch component and the spring fixing member are both mounted on the mounting plate. The door rotation switch component is connected to the sliding member so that when the door rotation switch component is adjusted, it drives the sliding member to move horizontally.

[0008] The door rotation switch component is used to drive the sliding member when it is adjusted from the first connection position to the second connection position, so that the sliding member moves horizontally away from the middle plate, thereby moving the bean outlet door horizontally from the first position to the second position. At this time, the bean outlet is connected to the bean outlet pipe.

[0009] The door rotation switch component is also used so that when the door is adjusted from the second connection position to the first connection position, the spring pushes the sliding member, causing the sliding member to move horizontally towards the middle plate, thereby causing the bean outlet door to move horizontally from the second position to the first position. At this time, the bean outlet is not connected to the bean outlet pipe.

[0010] In one embodiment, the door rotation switch component includes a crank handle, a rotating rod, a first eccentric wheel, and a second eccentric wheel. The crank handle is connected to the end of the rotating rod. The mounting plate has a first mounting through hole and a second mounting through hole. The rotating rod passes sequentially through the first mounting through hole, the through hole of the second eccentric wheel, the through hole of the first eccentric wheel, and the second mounting through hole. Both the first eccentric wheel and the second eccentric wheel are fixedly connected to the rotating rod. A clearance groove is formed between the first eccentric wheel and the second eccentric wheel. The outer wall of the bean outlet pipe is disposed in the clearance groove. Both the first eccentric wheel and the second eccentric wheel abut against the sliding member so that when the crank handle is rotated, it pushes the first eccentric wheel and the second eccentric wheel to rotate.

[0011] When the crank handle is rotated from the first rotation position to the second rotation position, the first eccentric wheel and the second eccentric wheel push the sliding member, causing the sliding member to move horizontally away from the middle plate, thereby causing the bean outlet door to move horizontally from the first position to the second position. At this time, the bean outlet is connected to the bean outlet pipe.

[0012] The crank handle is also used to push the sliding member when rotating from the second rotation position to the first rotation position, so that the sliding member moves horizontally towards the middle plate, thereby causing the bean outlet door to move horizontally from the second position to the first position. At this time, the bean outlet is not connected to the bean outlet pipe.

[0013] In one embodiment, the first eccentric wheel has a first abutting surface, the second eccentric wheel has a second abutting surface, the first abutting surface and the second abutting surface are disposed opposite to each other, and both the first abutting surface and the second abutting surface are used to abut against the bean outlet pipe, so that the bean outlet pipe is movably disposed relative to the trajectory formed between the first abutting surface and the second abutting surface.

[0014] In one embodiment, the second eccentric wheel is provided with a limiting protrusion, which is disposed on the second abutment surface so that when the bean outlet is in communication with the bean outlet pipe and the second abutment surface abuts against the bean outlet pipe, the limiting protrusion prevents the rotating rod from rotating.

[0015] In one embodiment, the door rotation switch component includes a pull handle, a pull rod, and a limit stop. The pull handle is fixedly connected to the pull rod, and the limit stop is mounted on the mounting plate. The mounting plate has a handle through hole, and the sliding member has a rotation through hole. The pull rod passes through the handle through hole and the rotation through hole in sequence, so that the pull rod is rotatably connected relative to the sliding member. The pull handle is used to pull the sliding member to move horizontally, and the limit stop and the mounting plate are both used to abut against the pull handle.

[0016] When the pull handle is rotated from the first rotation position to the second rotation position, the pull rod pulls the sliding member, causing the sliding member to move horizontally away from the middle plate, thereby causing the bean outlet door to move horizontally from the first position to the second position. At this time, the pull handle abuts against the limiting block, and the bean outlet is connected to the bean outlet pipe.

[0017] The pull handle is also used to push the sliding member when rotating in the opposite direction from the second rotation position to the first rotation position, so that the sliding member moves horizontally towards the middle plate, thereby causing the bean outlet door to move horizontally from the second position to the first position. At this time, the pull handle abuts against the mounting plate, and the bean outlet is not connected to the bean outlet pipe.

[0018] In one embodiment, the limiting block has a limiting groove, which is used to limit the pull handle when the bean outlet door moves horizontally from the first position to the second position.

[0019] In one embodiment, the coffee bean roasting mechanism further includes a drive member connected to the sliding member, the sliding member having a central hole, the drive end of the drive member passing through the central hole, and the bean outlet door connected to the drive end of the drive member.

[0020] In one embodiment, the slider includes a slide rail and a sliding plate, the sliding plate being slidably disposed on the slide rail, the slide rail having a starting end and a ending end, so that the sliding plate slides horizontally between the starting end and the ending end.

[0021] When the sliding plate slides horizontally from the end to the beginning, the bean outlet door moves horizontally from the first position to the second position, at which time the bean outlet is connected to the bean outlet pipe.

[0022] The sliding plate is also used so that when it slides horizontally from the starting end to the ending end, the bean outlet door moves horizontally from the second position to the first position, at which time the bean outlet is not connected to the bean outlet pipe.

[0023] In one embodiment, the sliding plate has a spring limiting portion that passes through the inner wall of the spring and is located within the receiving groove.

[0024] A coffee roaster includes the coffee bean roasting mechanism described in any of the above embodiments.

[0025] Compared with the prior art, this disclosure has at least the following advantages:

[0026] 1. The coffee bean roasting mechanism uses a manually operated door rotary switch to control the door's open or closed state. When roasting is complete and the door needs to be opened, the switch can be manually operated to move it from the first connection position to the second connection position. During this process, the switch moves the sliding component, which, since the bean outlet door is connected to the sliding component, moves it away from the middle plate, thus opening the door. This allows the coffee beans in the roasting assembly to pass through the bean outlet pipe to the bean receiving assembly. The switch can be released to keep the door in the second connection position. When the door needs to be closed, the switch can be manually operated to move it from the second connection position to the first connection position. During this process, a spring pushes the sliding component back, causing it to move the bean outlet door closer to and abut against the middle plate, thus closing the door. In this way, the mechanism can keep the door open in one position and closed in another.

[0027] 2. When the coffee bean roasting mechanism uses specific components such as a crank handle, if it is necessary to open the chamber door, the crank handle can be manually rotated at a certain angle. At this time, the first and second eccentric wheels push the sliding member, causing the sliding member to move the bean chamber door away from the middle plate, thereby opening the chamber door. When one side of the first and second eccentric wheels abuts against the sliding member, the chamber door can be kept open without manual maintenance. When it is necessary to close the chamber door, the crank handle can be rotated in the opposite direction at a certain angle. At this time, the spring pushes the sliding member, causing the sliding member to move the bean chamber door closer to the middle plate and abut against it, thereby closing the chamber door. In this way, it is possible to keep the chamber door open when the crank handle is rotated at one angle and keep the chamber door closed when the crank handle is rotated at another angle.

[0028] 3. When the coffee bean roasting mechanism uses a pull handle or similar components, to open the hopper door, the pull handle can be manually grasped and pulled a certain distance away from the mounting plate. Then, rotate it a certain angle to keep the door open against the outer wall of the limit stop. No manual intervention is required. During this process, the sliding component is pulled by the lever, causing it to move the bean hopper door away from the middle plate. To close the door, the pull handle can be manually grasped and pulled a certain distance away from the limit stop. Then, rotate it a certain angle and gradually reduce the force applied to the pull handle. During this process, the spring pushes the sliding component back, causing it to move the bean hopper door closer to the middle plate and abut against it, thus closing the door. This allows the door to remain open when the pull handle is against the limit stop and closed when the pull handle is against the mounting plate. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0052] Please see Figures 1 to 16 This is a coffee bean roasting mechanism 10 according to an embodiment of the present invention, including a mounting plate 100, a middle plate 200, a roasting assembly 300, a bean outlet pipe 400, a bean receiving assembly 500, and a door switch control assembly 600. The middle plate 200 is connected to the mounting plate 100, and the middle plate 200 has a bean outlet 201 and a bean receiving outlet 202. The roasting assembly 300, the bean receiving assembly 500, and the bean outlet pipe 400 are all connected to the middle plate 200. Furthermore, the bean outlet pipe 400 is also connected to the mounting plate 100, the bean drying assembly 300 has a baking cavity 301, the baking cavity 301 is connected to the bean outlet 201; the bean outlet pipe 400 is connected to the bean receiving port 202, the bean outlet pipe 400 has a control through hole 401, and the bean outlet pipe 400 is set on the mounting plate 100; the bean receiving assembly 500 has a bean receiving cavity 501, and the bean receiving port 202 is connected to the bean receiving cavity 501.

[0053] like Figure 1 , Figures 4 to 12 As shown, in one embodiment, the silo door switch control assembly 600 includes a silo door rotary switch component 610, a slider 620, a bean outlet silo door 630, a spring 640, and a spring fixing component 650. The slider 620 is movably disposed on the bean outlet pipe 400, and the bean outlet silo door 630 is located inside the bean outlet pipe 400. The end of the bean outlet silo door 630 also passes through the control through hole 401 and is fixedly connected to the slider 620. The spring fixing component 650 has a receiving groove. The two ends of the spring 640 abut against the spring fixing component 650 and the slider 620 respectively, and the spring 640 is located in the receiving groove. The silo door rotary switch component 610 and the spring fixing component 650 are both disposed on the mounting plate 100. The silo door rotary switch component 610 is connected to the slider 620 so that when the silo door rotary switch component 610 is adjusted, it drives the slider 620 to move horizontally, specifically by pushing or pulling the slider 620 to move horizontally.

[0054] In one embodiment, the door rotation switch component 610 is used to drive the sliding member 620 when adjusting from the first connection position to the second connection position, causing the sliding member 620 to move horizontally away from the middle plate 200, thereby causing the bean outlet door 630 to move horizontally from the first position to the second position. At this time, the bean outlet 201 is connected to the bean outlet pipe 400, that is, the door is in the open state, and the spring 640 is subjected to compression force. The first position is the position where the bean outlet door 630 is against the middle plate 200, and the second position is the position where the bean outlet door 630 is away from the bean outlet 201. The corresponding state effect diagram is shown below. Figure 7 or Figure 12 As shown.

[0055] In another embodiment, the door rotation switch component 610 is also used to, when adjusted from the second connection position to the first connection position, have the spring 640 push the slider 620, causing the slider 620 to move horizontally towards the middle plate 200, thereby causing the bean outlet door 630 to move horizontally from the second position to the first position. At this time, the bean outlet 201 is not connected to the bean outlet pipe 400, that is, the door is in the closed state. The corresponding state effect diagram is shown below. Figure 5 or Figure 10 As shown.

[0056] It should be noted that the aforementioned warehouse gate specifically refers to soybean warehouse gate 630.

[0057] Since the coffee bean roasting mechanism 10 uses a manually operated door rotary switch component 610 to control the door to be in an open or closed state, when the door needs to be opened after roasting, it can be manually controlled to adjust the door rotary switch component 610 from a first connection position to a second connection position. During this process, the component drives the sliding member 620. Since the bean outlet door 630 is connected to the sliding member 620, the bean outlet door 630 is moved away from the middle plate 200, thereby opening the door. Finally, the coffee beans located in the roasting assembly 300 pass through the bean outlet pipe 400. When the bean receiving assembly 500 is reached, the hand can be released to keep the hopper door rotary switch component 610 in the second connection position. When it is necessary to close the hopper door, the hopper door rotary switch component 610 can be manually controlled to adjust the hopper door rotary switch component 610 from the second connection position to the first connection position. During this process, the spring 640 pushes the slider 620 by rebounding, so that the slider 620 drives the bean hopper door 630 to approach and abut against the middle plate 200, thereby achieving the effect of closing the hopper door. In this way, the mechanism can keep the hopper door open in one position and keep the hopper door closed in another position.

[0058] In this embodiment, as Figure 5 , Figure 7 , Figure 10 or Figure 12As shown, a portion of the bean outlet pipe 400 is inserted into the bean receiving port 202 so that the coffee beans can fall into the bean receiving basket of the bean receiving assembly 500 after roasting, wherein the bean receiving basket is located inside the bean receiving cavity 501.

[0059] like Figures 1 to 7 As shown, in one embodiment, the door rotation switch component 610 includes a crank handle 611, a rotating rod 612, a first eccentric wheel 613, and a second eccentric wheel 614. The crank handle 611 is connected to the end of the rotating rod 612. The mounting plate 100 has a first mounting through hole 101 and a second mounting through hole 102. The rotating rod 612 passes through the first mounting through hole 101, the through hole of the second eccentric wheel 614, the through hole of the first eccentric wheel 613, and the second eccentric wheel 614 in sequence. The mounting hole 102 is installed, and the first eccentric wheel 613 and the second eccentric wheel 614 are both fixedly connected to the rotating rod 612. A clearance groove 610a is formed between the first eccentric wheel 613 and the second eccentric wheel 614. The outer wall of the bean outlet pipe 400 is set in the clearance groove 610a. The first eccentric wheel 613 and the second eccentric wheel 614 abut against the sliding member 620 so that when the crank handle 611 is rotated, it pushes the first eccentric wheel 613 and the second eccentric wheel 614 to rotate.

[0060] In this embodiment, when the crank handle 611 is rotated from the first rotational position to the second rotational position, the first eccentric wheel 613 and the second eccentric wheel 614 push the slider 620, causing the slider 620 to move horizontally away from the middle plate 200, thereby causing the bean outlet door 630 to move horizontally from the first position to the second position. At this time, the bean outlet 201 is connected to the bean outlet pipe 400, and the corresponding state effect diagram is shown below. Figure 6 and Figure 7 As shown;

[0061] In another embodiment, the crank handle 611 is also used to, when rotated in the opposite direction from the second rotational position to the first rotational position, push the slider 620, causing the slider 620 to move horizontally towards the middle plate 200, thereby causing the bean outlet door 630 to move horizontally from the second position to the first position. At this time, the bean outlet 201 is not connected to the bean outlet pipe 400, and the corresponding state effect diagram is as follows. Figure 4 and Figure 5 As shown.

[0062] It is understandable that, since the first eccentric wheel 613 and the second eccentric wheel 614 are fixed on the rotating rod 612, when the crank handle 611 is turned, the crank handle 611 rotates about the center point of the rotating rod 612 as the axis of rotation, thereby driving the first eccentric wheel 613 and the second eccentric wheel 614 to rotate. When the crank handle 611 rotates from the first rotation position forward to the second rotation position, that is, clockwise to the second rotation position, the first eccentric wheel 613 and the second eccentric wheel 614 follow the clockwise rotation and push the sliding plate 622 to slide horizontally away from the middle plate 200, thereby indirectly driving the bean outlet door 630 away from the bean outlet opening 201, so as to achieve the effect of opening the door. When one side of the first eccentric wheel 613 and the second eccentric wheel 614 is kept in contact with the sliding member 620, the door can be kept in the open state without applying pressure to the crank handle 611 to maintain it. At this time, the bean outlet opening 201 and the bean outlet... Pipe 400 is connected, and spring 640 is subjected to compressive force. When the crank handle 611 is rotated from the second rotation position to the first rotation position, that is, rotated counterclockwise to the first rotation position, the first eccentric wheel 613 and the second eccentric wheel 614 rotate counterclockwise. At this time, the thrust of the first eccentric wheel 613 and the second eccentric wheel 614 on the sliding member 620 gradually decreases. Due to the rebound characteristic of spring 640, the sliding member 620 is pushed by spring 640 and moves towards the middle plate 200, thereby indirectly driving the bean outlet door 630 to approach the bean outlet 201 and abut against the middle plate 200, so as to achieve the effect of closing the door.

[0063] Furthermore, combined Figures 2 to 7As shown, the first eccentric wheel 613 has a first helical semi-circular surface 613a and a first abutting surface 613b. The first helical semi-circular surface 613a is distributed along the outer periphery of the first eccentric wheel 613, gradually moving away from the rotating rod 612. The first abutting surface 613b is located on the outer side of the first helical semi-circular surface 613a, away from the rotating rod 612. The second eccentric wheel 614 has a second helical semi-circular surface 614a and a second abutting surface 614b. The second helical semi-circular surface 614a is distributed along the outer periphery of the second eccentric wheel 614, gradually moving away from the rotating rod 612. The second abutting surface 614b is located on the outer side of the second helical semi-circular surface 614a, away from the rotating rod 612. The first helical semi-circular surface 613a, the second helical semi-circular surface 614a, the first abutting surface 613b, and the second abutting surface 614b are all used to abut against the sliding member 620. In this embodiment, when the handle 611 is manually cranked from the first rotation position to the second rotation position, the first eccentric wheel 613 and the second eccentric wheel 614 rotate accordingly. During the rotation, the sliding member 620 abuts against the first helical semi-circular surface 613a and the second helical semi-circular surface 614a, and gradually moves away from the middle plate 200 along the first helical semi-circular surface 613a and the second helical semi-circular surface 614a until the first abutting surface 613b and the second abutting surface 614b abut against the sliding member 620. At this point, the distance between the sliding member 620 and the rotating rod 612 is at its maximum value, and the bean hopper door 630 is located in the second position, that is, the position away from the middle plate 200. It can achieve the effect of opening and keeping the hopper door open; when the crank handle 611 is rotated from the second rotation position to the first rotation position, the first abutment surface 613b and the second abutment surface 614b gradually move away from the slider 620, and the first helical semi-circular surface 613a and the second helical semi-circular surface 614a abut against the slider 620. Then, under the rebound action of the spring 640, the slider 620 gradually moves closer to the middle plate 200 along the first helical semi-circular surface 613a and the second helical semi-circular surface 614a until the distance between it and the rotating rod 612 reaches the minimum value. At this time, the bean hopper door 630 abuts against the middle plate 200 to achieve the effect of closing the hopper door.

[0064] Furthermore, rotating the handle 611 from the first rotation position to the second rotation position indicates a clockwise rotation of 90°, and rotating the handle 611 from the second rotation position to the first rotation position indicates a counterclockwise rotation of 90°. That is, the angle formed between the extension line of the first rotation position and the extension line of the second rotation position is 90°.

[0065] like Figure 3As shown, the first eccentric wheel 613 further has a first abutting surface 613c, and the second eccentric wheel 614 has a second abutting surface 614c. The first abutting surface 613c and the second abutting surface 614c are arranged opposite to each other, that is, both the first abutting surface 613c and the second abutting surface 614c are arranged facing the bean outlet pipe 400, and both the first abutting surface 613c and the second abutting surface 614c are used to abut against the bean outlet pipe 400, so that the bean outlet pipe 400 is movable relative to the trajectory formed between the first abutting surface 613c and the second abutting surface 614c. In this way, since the bean outlet pipe 400 is fixed on the mounting plate 100, if it is necessary to adjust the position of the rotating rod 612, it can be adjusted by pushing and pulling the handle 611, so that the trajectory is movable relative to the bean outlet pipe 400. That is, with the bean outlet pipe 400 as the reference system, the trajectory formed between the first abutting surface 613c and the second abutting surface 614c is movable. Furthermore, the second eccentric wheel 614 is provided with a limiting protrusion 614d, which is located on the second abutment surface 614c. When the bean outlet 201 is connected to the bean outlet pipe 400, and the second abutment surface 614c abuts against the bean outlet pipe 400, the limiting protrusion 614d prevents the rotating rod 612 from rotating. It can be understood that when the hopper door is open, i.e., the bean outlet 201 is connected to the bean outlet pipe 400, if the crank handle 611 is manually pushed to move closer to the bean outlet pipe 400, the second eccentric wheel 614 moves closer to the bean outlet pipe 400, and the second abutment surface 614c abuts against the bean outlet pipe 400. The limiting protrusion 614d is located above the bean outlet pipe 400. Thus, with the second abutment surface 614c abutting against the bean outlet pipe 400, it prevents the user from accidentally rotating or cranking the wheel. Handle 611, thus, the setting of the limiting protrusion 614d can further ensure that the hopper door is stably kept in the open state; in another embodiment, when the hopper door is in the closed state, that is, the bean outlet 201 is not connected to the bean outlet pipe 400, the first abutment surface 613c and the limiting protrusion 614d both abut against the outer wall of the bean outlet pipe 400, which can prevent the crank handle 611 from being pushed and pulled to adjust when the hopper door is closed, reducing the wear of the rotating rod 612. At this time, there is a certain gap between the second abutment surface 614c and the bean outlet pipe 400.

[0066] In this embodiment, the first eccentric wheel 613 and the second eccentric wheel 614 are both fixedly connected to the rotating rod 612 by screws, so that the connection between the first eccentric wheel 613 and the second eccentric wheel 614 and the rotating rod 612 is relatively secure.

[0067] like Figures 2 to 4As shown, further, the crank handle 611 includes a handle 6111, a positioning shaft 6112, and a gripping post 6113. One end of the handle 6111 is connected to the positioning shaft 6112, and the other end of the handle 6111 is connected to the rotating rod 612. The gripping post 6113 has a clearance through hole 611a, and the positioning shaft 6112 also passes through the clearance through hole 611a, so that the gripping post 6113 can be movably arranged around the positioning shaft 6112. At this time, the gripping post 6113 can be centered on the positioning shaft 6112. The central rotation allows for easy understanding. Whenever the compartment door is opened or closed, the operator first grasps the grip post 6113, then applies force to cause the handle 6111 to rotate around the rotating rod 612. During this rotation, although the grip post 6113 follows the handle 6111's circular motion, the positioning axis 6112 moves relative to the grip post 6113, thus maintaining a consistent hand posture while turning the crank handle 611, making operation more convenient. Furthermore, the handle 6111 and the rotating rod 612 are connected by screws to ensure a secure connection.

[0068] like Figures 8 to 12 As shown, in another embodiment, the door rotation switch component 610 includes a pull handle 615, a pull rod 616, and a limit stop 617. The pull handle 615 is fixedly connected to the pull rod 616, and the limit stop 617 is installed on the mounting plate 100. The mounting plate 100 has a handle through hole 103, and the sliding member 620 has a rotation through hole 6202. The pull rod 616 passes through the handle through hole 103 and the rotation through hole 6202 in sequence, so that the pull rod 616 is rotatably connected to the sliding member 620. The pull handle 615 is used to pull the sliding member 620 to move horizontally, and the limit stop 617 and the mounting plate 100 are both used to abut against the pull handle 615.

[0069] In this embodiment, when the handle 615 is pulled to rotate from the first rotation position to the second rotation position, the pull rod 616 pulls the sliding member 620, causing the sliding member 620 to move horizontally away from the middle plate 200, thereby causing the bean outlet door 630 to move horizontally from the first position to the second position. At this time, the handle 615 abuts against the limiting block 617, and the bean outlet 201 is connected to the bean outlet pipe 400. The corresponding effect state diagram is shown below. Figure 12 As shown;

[0070] In another embodiment, when the pull handle 615 is rotated in the opposite direction from the second rotation position to the first rotation position, the spring 640 pushes the slider 620, causing the slider 620 to move horizontally towards the middle plate 200, thereby causing the bean outlet door 630 to move horizontally from the second position to the first position. At this time, the pull handle 615 abuts against the mounting plate 100, and the bean outlet 201 is not connected to the bean outlet pipe 400. The corresponding effect state diagram is shown below. Figure 10 As shown.

[0071] It is understandable that, since the pull handle 615 can drive the sliding member 620 to move horizontally via the pull rod 616, and the pull handle 615 and the pull rod 616 can also rotate around the handle through hole 103, when the pull handle 615 rotates from the first rotation position to the second rotation position, the specific steps are as follows: First, pull the pull handle 615 outward, away from the mounting plate 100, so as to drive the sliding member 620 to move horizontally away from the middle plate 200, thereby driving the bean outlet door 630 away from the middle plate 200, thus achieving the effect of opening the door, that is, the bean outlet 201 is connected to the bean outlet pipe 400. Then, rotate the pull handle 615 so that the pull handle 615 abuts against the limit stop 617, which is recorded as the second rotation position, thereby making the pull handle 615 and the mounting plate 103... A certain distance exists between and is maintained between the two parts, corresponding to the straight-line distance between the bean outlet door 630 and the middle plate 200. In this state, manual force can be released, and the door can be kept open. When the handle 615 is rotated from the second rotation position to the first rotation position, the specific steps are as follows: First, the handle 615 is pulled outward to move it away from the limit block 617. Then, the handle 615 is rotated, and manual force is gradually released until the handle 615 abuts against the mounting plate 100, which is recorded as the first rotation position. During this period, under the action of the spring 640, the sliding member 620 is pushed, causing it to move horizontally towards the middle plate 200, thereby causing the bean outlet door 630 to gradually approach the middle plate 200 and finally abut against the middle plate 200, thus maintaining the closed door. In this embodiment, there are two limit blocks 617.

[0072] Furthermore, an air-avoidance channel is formed between the two limit blocks 617. When the pull handle 615 rotates from the first rotation position to the second rotation position, the pull handle 615 abuts against the two limit blocks 617. When the pull handle 615 rotates from the second rotation position to the first rotation position, the pull handle 615 is located in the air-avoidance channel.

[0073] In another embodiment, when the handle 615 is rotated in the opposite direction from the first rotation position to the third rotation position, the lever 616 drives the slider 620 to move horizontally away from the middle plate 200, thereby causing the bean outlet door 630 to move horizontally from the first position to the third position. At this time, the handle 615 abuts against the limit block 617, and the bean outlet 201 is connected to the bean outlet pipe 400.

[0074] In another embodiment, when the pull handle 615 is rotated forward from the third rotation position to the first rotation position, the spring 640 pushes the slider 620, causing the slider 620 to move horizontally towards the middle plate 200, thereby causing the bean outlet door 630 to move horizontally from the third position to the first position. At this time, the pull handle 615 abuts against the mounting plate 100, and the bean outlet 201 is not connected to the bean outlet pipe 400.

[0075] Furthermore, pulling handle 615 from the first rotation position to the second rotation position represents a 90° clockwise rotation; pulling handle 615 from the second rotation position to the first rotation position represents a 90° counterclockwise rotation; pulling handle 615 from the first rotation position to the third rotation position represents a 90° counterclockwise rotation; and pulling handle 615 from the third rotation position to the first rotation position represents a 90° clockwise rotation. In other words, the angle formed by the extension lines of the first and second rotation positions is 90°, the angle formed by the extension lines of the first and third rotation positions is 90°, and the angle formed by the extension lines of the second and third rotation positions is 180°.

[0076] Furthermore, such as Figure 8 and Figure 9 As shown, the limiting block 617 has a limiting groove 6171, which is used to limit the pull handle 615 when the bean outlet door 630 moves horizontally from the first position to the second position. It can be understood that when the pull handle 615 is pulled outward and rotated at a certain angle to abut against the limiting block 617, it is located within the limiting groove 6171. Since the straight-line distance between the bottom of the limiting groove 6171 and the mounting plate 100 is less than the straight-line distance between the outer side of the limiting block 617 and the mounting plate 100, when the limiting groove 6171 restricts the pull handle 615, it can prevent the door from being accidentally closed due to user error in rotating the pull handle 615, further ensuring that the door is in the open state, i.e., keeping the bean outlet door 630 away from the middle plate 200. In this embodiment, both limiting blocks 617 have limiting grooves 6171, and the center lines of the two limiting grooves 6171 coincide.

[0077] like Figures 10 to 13 , Figure 16As shown, in one embodiment, the pull rod 616 includes a traction part 6161 and a connecting part 6162. The connecting part 6162 passes through the rotating through hole 6202. Both ends of the connecting part 6162 are connected to the traction part 6161 and the pull handle 615, respectively. The traction part 6161 abuts against the side of the sliding member 620 facing away from the mounting plate 100. When it is necessary to open or close the compartment door, the pull handle 615 is first pulled outwards, and the traction part 6161 also follows, pulling the sliding member 620. Then, the pull handle 615 is rotated at a certain angle to prepare for opening or closing the compartment door. Furthermore, the traction part 6161 and the connecting part 6162 form an integrally molded structure, making the structure of the traction part 6161 and the connecting part 6162 more compact and reliably connected. They only need to be manufactured in one step without secondary processing. In this embodiment, the cross-sectional diameter of the traction part 6161 is larger than the cross-sectional diameter of the connecting part 6162.

[0078] Furthermore, such as Figures 8 to 14 As shown, the pull handle 615 includes a handle body 6151, a pull shaft 6152, and a locking member 6153. The handle body 6151 has a first connecting hole 615a, and the pull shaft 6152 has a second connecting hole 615b. The locking member 6153 passes through the first connecting hole 615a and the second connecting hole 615b in sequence to connect the handle body 6151 and the pull shaft 6152. The pull shaft 6152 also has a mounting positioning hole 615c, and the pull rod 616 passes through the mounting positioning hole 615c to securely connect the pull shaft 6152 and the pull rod 616. The mounting plate 100 and the limiting block 617 are both used to abut against the pull shaft 6152. In this embodiment, the connecting part 6162 passes through the mounting positioning hole 615c. It is understandable that when opening or closing the hopper door, the person first grasps the handle body 6151 and pulls it outward. The handle body 6151 drives the pull shaft 6152, which in turn drives the pull rod 616, thereby indirectly causing the sliding member 620 and the bean outlet door 630 to move horizontally. Due to the locking member 6153, the handle body 6151 will not disengage from the pull shaft 6152 when the handle body 6151 is pulled outward, ensuring that the hopper door can be opened or closed normally. In this embodiment, the connecting part 6162 passes through the mounting positioning hole 615c.

[0079] In this embodiment, the limiting groove 6171 is used to limit the pulling of the rotating shaft 6152 when the bean outlet door 630 moves horizontally from the first position to the second position.

[0080] Furthermore, such as Figure 14As shown, the locking member 6153 includes a supporting part 61531, a cylindrical part 61532 and a spiral locking part 61533 connected in sequence. The supporting part 61531 abuts against the handle body 6151, the cylindrical part 61532 is located in the first connecting hole 615a, and the spiral locking part 61533 is located in the second connecting hole 615b. In this embodiment, the outer wall of the cylindrical part 61532 is smooth, and the inner wall of the first connecting hole 615a is smooth; the outer wall of the spiral locking part 61533 is spiral-shaped, and the inner wall of the second connecting hole 615b is spiral-shaped. This allows the handle body 6151 to rotate freely around the locking member 6153, and the locking member 6153 always maintains a stable connection. Thus, after the door is closed, the handle body 6151 is moved so that it rests against the mounting plate 100. Furthermore, the handle body 6151 has a clearance opening, which is used to accommodate the limiting block 617 when the handle 615 is pulled from the second rotation position to the first rotation position, ensuring the flatness of the limiting block 617 and the pull handle 615, and also making it easy for the handle body 6151 not to protrude significantly when the coffee roaster body is stored in any container.

[0081] Furthermore, such as Figure 14 and Figure 15 As shown, the pull handle 615 also includes a spiral nail 6154, the pull shaft 6152 has an anti-detachment screw hole 615d, and the pull rod 616 has a connecting through hole 616a. The threaded part of the spiral nail 6154 passes through the anti-detachment screw hole 615d and the connecting through hole 616a in sequence, so that the pull rod 616 is firmly connected to the pull shaft 6152, preventing the pull rod 616 from disengaging from the pull shaft 6152 when the handle 615 body is pulled, and ensuring that the door can be opened or closed normally.

[0082] Furthermore, combining Figure 12 and Figure 13 As shown, the pull rod 616 also includes a through part 6163, which is connected to the connecting part 6162. A connecting through hole 616a is provided in the through part 6163. The threaded part of the spiral nail 6154 is sequentially passed through the anti-loosening screw hole 615d and the connecting through hole 616a, so that the through part 6163 is firmly connected to the pulling shaft 6152.

[0083] like Figure 17 As shown, in one embodiment, the slider 620 includes a slide rail 621 and a sliding plate 622. The sliding plate 622 is slidably disposed on the slide rail 621. The slide rail 621 has a starting end 6211 and a ending end 6212, so that the sliding plate 622 slides horizontally between the starting end 6211 and the ending end 6212.

[0084] Combination Figure 7 and Figure 12As shown, when the sliding plate 622 slides horizontally from the end 6212 to the beginning 6211, the bean outlet door 630 moves horizontally from the first position to the second position, at which time the bean outlet 201 is connected to the bean outlet pipe 400.

[0085] Combination Figure 5 and Figure 10 As shown, the sliding plate 622 is also used to move the bean outlet door 630 from the second position to the first position when it slides horizontally from the starting end 6211 to the ending end 6212. At this time, the bean outlet 201 is not connected to the bean outlet pipe 400.

[0086] It is understandable that when the sliding plate 622 is at the end 6212, it means that the bean outlet door 630 is against the middle plate 200. At this time, the bean outlet 201 is not connected to the bean outlet pipe 400. If the door is to be opened, the door rotation switch component 610 drives the sliding plate 622 to move horizontally on the slide rail 621 until the sliding plate 622 reaches the starting end 6211, at which point the bean outlet door 630 is in a state away from the middle plate 200. If the door is to be closed, the door rotation switch component 610 gradually reduces the force on the sliding plate 622. At this time, the spring 640 rebounds and pushes the sliding plate 622 to move horizontally on the slide rail 621 until the sliding plate 622 reaches the end 6212, at which point the bean outlet door 630 is against the middle plate 200. In this way, the sliding plate 622 moves along the trajectory between the starting end 6211 and the ending end 6212 of the slide rail 621, preventing it from moving beyond the starting end 6211 and the ending end 6212, that is, preventing the sliding plate 622 from disengaging from the slide rail 621.

[0087] In another embodiment, such as Figure 17 As shown, the starting end 6211 is flush with one end of the spring fixing member 650 so that when the sliding plate 622 reaches the starting end 6211, it abuts against the spring fixing member 650.

[0088] In one embodiment, such as Figure 17 As shown, the sliding plate 622 has a spring limiting part 6221, which passes through the inner wall of the spring 640 and is located in the receiving groove, so that the two ends of the spring 640 abut against the spring fixing member 650 and the sliding plate 622 respectively. Thus, when the door rotating switch component 610 drives the sliding member 620 to move horizontally, the spring limiting part 6221 is easily squeezed. When the door rotating switch component 610 releases the force on the sliding member 620, the spring 640 pushes the sliding member 620. During this period, the spring limiting part 6221 passes through the interior of the spring 640, and the spring 640 is located in the spring fixing member 650, thereby limiting the spring 640 and preventing the spring 640 from detaching from the spring fixing member 650. This ensures that when the spring 640 rebounds, it normally pushes the sliding plate 622 to move horizontally towards the middle plate 200.

[0089] In another embodiment, such as Figure 10 As shown, the coffee bean roasting mechanism 10 also includes a drive member 700, which is connected to a sliding member 620. The sliding member 620 has a central hole 6201, and the drive end of the drive member 700 passes through the central hole 6201. The bean outlet door 630 is connected to the drive end of the drive member 700. It is understandable that, with the drive unit 700 installed, the coffee bean roasting mechanism 10 can open or close the chamber door not only manually but also electrically. Thus, when the bean outlet door 630 is indirectly pressed against the middle plate 200 via the door rotation switch 610, the drive unit 700 can be controlled via the control panel or remote operation to drive the bean outlet door 630 away from the middle plate 200 so that the bean outlet 201 connects to the bean outlet pipe 400. When the bean outlet door 630 is indirectly pressed away from the middle plate 200 via the door rotation switch 610, the drive unit 700 can be controlled via the control panel or remote operation to drive the bean outlet door 630 gradually closer to and against the middle plate 200. This diversifies the specific operation of controlling the opening and closing of the coffee roaster's chamber door; it can be controlled manually or electrically. In this embodiment, the axial hole 6201 is located on the sliding plate 622.

[0090] This disclosure also provides a coffee roaster, including the coffee roasting mechanism 10 of any of the above embodiments.

[0091] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0092] 1. Since the coffee bean roasting mechanism 10 uses a manually operated door rotation switch component 610 to control the door to be in an open or closed state, when the door needs to be opened after roasting, it can be manually controlled to adjust the door rotation switch component 610 from the first connection position to the second connection position. During this process, the component drives the sliding member 620. Since the bean outlet door 630 is connected to the sliding member 620, the bean outlet door 630 is moved away from the middle plate 200, thereby opening the door. Finally, the coffee beans located in the roasting assembly 300 pass through the bean outlet pipe 40. When the bean receiving assembly 500 is reached, the hand can be released to keep the door rotation switch component 610 in the second connection position. When it is necessary to close the door, the door rotation switch component 610 can be manually controlled to adjust the door rotation switch component 610 from the second connection position to the first connection position. During this process, the spring 640 pushes the slider 620 by rebounding, so that the slider 620 drives the bean hopper door 630 to approach and abut against the middle plate 200, thereby achieving the effect of closing the door. In this way, the mechanism can keep the door open in one position and keep the door closed in another position.

[0093] 2. When the coffee bean roasting mechanism 10 uses specific components such as a crank handle 611, if it is necessary to open the chamber door, the crank handle 611 can be manually rotated at a certain angle. At this time, the first eccentric wheel 613 and the second eccentric wheel 614 push the sliding member 620, so that the sliding member 620 drives the bean hopper door 630 away from the middle plate 200, thereby opening the chamber door. When one side of the first eccentric wheel 613 and the second eccentric wheel 614 abuts against the sliding member 620, the chamber door can be kept in the open state without manual maintenance. When it is necessary to close the chamber door, the crank handle 611 can be rotated in the opposite direction at a certain angle. At this time, the spring 640 pushes the sliding member 620, so that the sliding member 620 drives the bean hopper door 630 close to the middle plate 200 and abuts against it, thereby closing the chamber door. In this way, it is possible to keep the chamber door open when the crank handle 611 is rotated at one angle, and keep the chamber door closed when the crank handle 611 is rotated at another angle.

[0094] 3. When the coffee bean roasting mechanism 10 uses specific components such as a pull handle 615, if it is necessary to open the chamber door, the pull handle 615 can be manually grasped and pulled a certain distance away from the mounting plate 100 to open the chamber door. Then, it can be rotated a certain angle to abut against the outer wall of the limit stop 617 to keep the chamber door in the open state. No manual maintenance is required. During this process, the sliding part 620 is pulled by the pull rod 616, causing the sliding part 620 to move the bean hopper door 630 away from the middle plate 200. When it is necessary to close the chamber door, it can be manually... Grasp the pull handle 615 and pull it a certain distance away from the limit stop 617. Then rotate it a certain angle and gradually reduce the force on the pull handle 615. During this time, the spring 640 pushes the slider 620 by rebounding, so that the slider 620 drives the bean hopper door 630 close to the middle plate 200 and abuts against it to close the hopper door. In this way, the hopper door can be kept open when the pull handle 615 abuts against the limit stop 617 and kept closed when the pull handle 615 abuts against the mounting plate 100.

[0095] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.

The spring fixing component has a receiving groove, and the two ends of the spring abut against the spring fixing component and the sliding component respectively, and the spring is located in the receiving groove. The silo door rotary switch component and the spring fixing component are both mounted on the mounting plate. The silo door rotary switch component is connected to the sliding component so that when the silo door rotary switch component is adjusted, it drives the sliding component to move horizontally. The door rotation switch component is used to drive the sliding member when it is adjusted from the first connection position to the second connection position, so that the sliding member moves horizontally away from the middle plate, thereby moving the bean outlet door horizontally from the first position to the second position. At this time, the bean outlet is connected to the bean outlet pipe. The door rotation switch component is also used so that when the door is adjusted from the second connection position to the first connection position, the spring pushes the sliding member, causing the sliding member to move horizontally towards the middle plate, thereby causing the bean outlet door to move horizontally from the second position to the first position. At this time, the bean outlet is not connected to the bean outlet pipe.

2. The coffee bean roasting mechanism of claim 1, wherein, The door rotation switch component includes a crank handle, a rotating rod, a first eccentric wheel, and a second eccentric wheel. The crank handle is connected to the end of the rotating rod. The mounting plate has a first mounting through hole and a second mounting through hole. The rotating rod passes through the first mounting through hole, the through hole of the second eccentric wheel, the through hole of the first eccentric wheel, and the second mounting through hole in sequence. The first eccentric wheel and the second eccentric wheel are both fixedly connected to the rotating rod. A clearance groove is formed between the first eccentric wheel and the second eccentric wheel. The outer wall of the bean outlet pipe is disposed in the clearance groove. The first eccentric wheel and the second eccentric wheel abut against the sliding member so that when the crank handle is rotated, it pushes the first eccentric wheel and the second eccentric wheel to rotate. When the crank handle is rotated from the first rotation position to the second rotation position, the first eccentric wheel and the second eccentric wheel push the sliding member, causing the sliding member to move horizontally away from the middle plate, thereby causing the bean outlet door to move horizontally from the first position to the second position. At this time, the bean outlet is connected to the bean outlet pipe. The crank handle is also used to push the sliding member when rotating from the second rotation position to the first rotation position, so that the sliding member moves horizontally towards the middle plate, thereby causing the bean outlet door to move horizontally from the second position to the first position. At this time, the bean outlet is not connected to the bean outlet pipe.

3. The coffee bean roasting mechanism of claim 2, wherein, The first eccentric wheel has a first abutting surface, and the second eccentric wheel has a second abutting surface. The first abutting surface and the second abutting surface are disposed opposite to each other, and both the first abutting surface and the second abutting surface are used to abut against the bean outlet pipe, so that the bean outlet pipe is movable relative to the trajectory formed between the first abutting surface and the second abutting surface.

4. The coffee bean roasting mechanism of claim 3, wherein, The second eccentric wheel is provided with a limiting protrusion, which is disposed on the second abutment surface so that when the bean outlet is connected to the bean outlet pipe and the second abutment surface abuts against the bean outlet pipe, the limiting protrusion prevents the rotating rod from rotating.

5. The coffee bean roasting mechanism of claim 1, wherein, The door rotation switch component includes a pull handle, a pull rod, and a limit stop. The pull handle is fixedly connected to the pull rod, and the limit stop is mounted on the mounting plate. The mounting plate has a handle through hole, and the sliding member has a rotation through hole. The pull rod passes through the handle through hole and the rotation through hole in sequence, so that the pull rod is rotatably connected relative to the sliding member. The pull handle is used to pull the sliding member to move horizontally, and the limit stop and the mounting plate are both used to abut against the pull handle. When the pull handle is rotated from the first rotation position to the second rotation position, the pull rod pulls the sliding member, causing the sliding member to move horizontally away from the middle plate, thereby causing the bean outlet door to move horizontally from the first position to the second position. At this time, the pull handle abuts against the limiting block, and the bean outlet is connected to the bean outlet pipe. The pull handle is also used to push the sliding member when rotating in the opposite direction from the second rotation position to the first rotation position, so that the sliding member moves horizontally towards the middle plate, thereby causing the bean outlet door to move horizontally from the second position to the first position. At this time, the pull handle abuts against the mounting plate, and the bean outlet is not connected to the bean outlet pipe.

6. The coffee bean roasting mechanism of claim 5, wherein, The limiting block has a limiting groove, which is used to limit the pull handle when the bean outlet door moves horizontally from the first position to the second position.

The sliding plate is slidably disposed on the slide rail. The slide rail has a starting end and a ending end, so that the sliding plate can slide horizontally between the starting end and the ending end. When the sliding plate slides horizontally from the end to the beginning, the bean outlet door moves horizontally from the first position to the second position, at which time the bean outlet is connected to the bean outlet pipe. The sliding plate is also used so that when it slides horizontally from the starting end to the ending end, the bean outlet door moves horizontally from the second position to the first position, at which time the bean outlet is not connected to the bean outlet pipe.

9. The coffee bean roasting mechanism according to claim 8, characterized in that, The sliding plate has a spring limiting part, which passes through the inner wall of the spring and is located in the receiving groove.
