Description

Technical Field

[0001] The present application relates to the field of coffee roasting, and in particular to a coffee roasting machine. Background Art

[0002] A coffee roaster is a device used to roast coffee beans in order to stimulate the flavor substances contained in the coffee beans so that the coffee made from the coffee beans meets the user's preferences.

[0003] In the prior art, when roasting coffee beans using a coffee roaster, a container containing the coffee beans needs to be installed and placed in the coffee roaster. Then, the coffee roaster is started to blow hot roasting air toward the coffee beans in the container, thereby completing the roasting of the coffee beans.

[0004] Regarding the above-mentioned related technologies, a certain amount of smoke will be generated when roasting coffee beans. The smoke will easily seep out from the gap between the top of the carrying container and the coffee roaster and produce odor, affecting the user experience. Summary of the Invention

[0005] In order to prevent users from easily noticing the odor caused by roasting smoke when using a coffee roaster, the present application provides a coffee roaster.

[0006] The coffee roasting machine provided in this application adopts the following technical solution:

[0007] A coffee roaster comprises a roaster body, a roasting seat, a driving ring, a lifting plate and a carrying plate;

[0008] The baking seat is mounted on the baking machine body, and the driving ring is rotatably engaged with the baking seat. The driving ring is equipped with a rotating driving rod. The driving ring is penetrated by a lifting slot, and the lifting slot extends in an arc shape.

[0009] The lifting plate is equipped with a lifting block, the bottom of which is plugged into and slidably engaged with the rotating groove, and the bottom of which is provided with a lifting inclined surface;

[0010] The carrying plate is mounted on the lifting plate, and the top of the carrying plate is used to mount a carrying container containing coffee beans;

[0011] The lifting plate is provided with a rotation clamping groove, and the carrying plate is provided with a rotation clamping rod, and the rotation clamping rod is clamped and matched with the rotation clamping groove.

[0012] By adopting the above technical solution, after the coffee bean container is mounted on top of the carrier plate, the user secures the rotating clamping rod with one hand and uses the other hand to rotate the drive ring by turning the drive rod. This causes the inner wall of the lifting groove to tightly fit the lifting inclined surface at the bottom of the lifting block, thereby raising the container and making the top of the container tightly fit against the coffee roaster. As a result, smoke is less likely to seep out of the coffee roaster, making it less likely for the user to notice the unpleasant odor caused by the roasting smoke when using the coffee roaster, thereby improving the user experience.

[0013] Optionally, there are a plurality of lifting slots, and the plurality of lifting slots are distributed circumferentially; there are a plurality of lifting blocks, and the plurality of lifting blocks are respectively arranged corresponding to each lifting slot.

[0014] The adoption of the above technical solution is conducive to improving the stability of the driving ring when driving the carrying plate to rise and fall.

[0015] Optionally, the material of the lifting block is elastic.

[0016] By adopting the above technical solution, after the carrying plate is raised to a desired height, the lifting block is deformed and engaged with the corners of the lifting slot, thereby locking the height of the carrying plate.

[0017] Optionally, the lifting block is made of plastic, rubber or silicone.

[0018] By adopting the above technical solution, it is helpful to ensure the friction between the lifting block and the corners of the lifting slot, thereby ensuring the stability of the carrier plate when it is locked.

[0019] Optionally, the coffee roaster further comprises a heating plate, which is mounted on the roaster body and located on top of the carrier plate. The heating plate is provided with an electric heating wire.

[0020] By adopting the above technical solution, the electric heating wire of the heating plate performs secondary combustion on the combustible odor particles in the smoke generated during roasting, thereby reducing the odor of the smoke, so that users are less likely to notice the odor caused by the roasting smoke when using the coffee roaster.

[0021] Optionally, the baking machine body is rotatably fitted with a shielding cover, and the shielding cover is used to cover the heating plate.

[0022] By adopting the above technical solution, the electric heating wire of the heating plate is not easily adhered to dust, thereby ensuring the secondary combustion efficiency of the heating plate and thus ensuring the odor removal effect of the smoke.

[0023] Optionally, the shielding cover is rotatably engaged with the roaster body via a connecting assembly, wherein the connecting assembly comprises a cover connecting seat, a locking handle and a cover rotating seat;

[0024] The cover connecting seat is installed on the baking machine body, and the cover connecting seat is slidably matched with a locking pin, the locking pin is magnetic, and a reset elastic member is provided between the locking pin and the cover connecting seat;

[0025] The locking handle is rotatably engaged with the cover connecting seat, and the locking handle is magnetic;

[0026] The shielding cover is rotatably matched with the cover rotating seat, and a locking hole is penetrated through the cover rotating seat. When the locking handle is rotated toward the direction close to the locking pin, the locking pin is penetrated into the locking hole.

[0027] By adopting the above technical solution, the locking handle is rotated and twisted so that the locking handle rotates in the direction close to the locking pin, and then the locking pin is attracted by the locking handle through magnetic force, and then the locking pin is passed through the locking hole, thereby firmly installing the cover rotating seat on the cover connecting seat, which is convenient and quick.

[0028] The locking handle is rotated and twisted to rotate the locking handle away from the locking pin, so that the locking pin retracts from the locking hole under the elastic force of the reset elastic member, thereby allowing the cover rotating seat to be quickly removed from the cover connecting seat, which is convenient and quick.

[0029] Optionally, the cover connecting seat is equipped with two guide plates, both of which are extended in the vertical direction, and the two guide plates are respectively tightly fitted on both sides of the cover rotating seat.

[0030] By adopting the above technical solution, it is easy to ensure that after the cover rotating seat is installed on the cover connecting seat, the locking hole is arranged opposite to the locking pin, so that the locking pin is easy to be plugged into the locking hole.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. After installing the coffee bean container on top of the carrier plate, the user secures the rotating clamping rod with one hand and uses the other hand to rotate the drive ring by turning the drive rod. This causes the inner wall of the lifting groove to fit tightly against the lifting slope at the bottom of the lifting block, thereby raising the container and making the top of the container fit tightly against the coffee roaster. This prevents smoke from seeping out of the coffee roaster, making it less likely for the user to notice the odor caused by the roasting smoke when using the coffee roaster, thereby improving the user experience.

[0033] 2. The heating coil of the heating plate performs secondary combustion on the combustible odor particles in the smoke generated during roasting, thereby reducing the odor of the smoke. This makes it difficult for users to detect the odor of the roasting smoke when using the coffee roaster.

[0034] 3. Turn and twist the locking handle so that it rotates toward the locking pin. The locking pin is then attracted to the locking handle by magnetic force, and then the locking pin is inserted into the locking hole, thereby firmly installing the cover rotating base on the cover connecting base. It is convenient and quick.

[0035] 4. Turn and twist the locking handle so that the locking handle rotates in the direction away from the locking pin, and then the locking pin retracts from the locking hole under the elastic force of the reset elastic member, so that the cover rotating seat can be quickly removed from the cover connecting seat, which is convenient and quick.

[0045] The following is combined with Figure 1-8 This application is described in further detail.

[0046] Embodiment 1:

[0047] The present application embodiment discloses a coffee roasting machine. Figures 1 to 3 The coffee roaster includes a roaster body, a roasting seat 1, a driving ring 2, a lifting plate 3 and a carrying plate 4.

[0048] Reference Figure 2 and Figure 3 The baking base 1 is fixedly mounted on the roaster body. The drive ring 2 is engaged and rotated into a rotation groove (not shown) on the baking base 1 via two rotating protrusions. A rotation drive rod 21 is fixedly mounted on one side of the drive ring 2. The rotation drive rod 21 rotates and passes through a guide groove in the roaster body, allowing the user to rotate the drive ring 2 by rotating the drive rod 21.

[0049] The drive ring 2 is provided with two lifting slots 201 extending in an arc shape and circumferentially distributed around the axis of the drive ring 2. A lifting plate 3 is located on top of the drive ring 2. Two lifting blocks 31 are mounted on the lifting plate 3. The bottoms of the two lifting blocks 31 are respectively inserted and slidably engaged with the respective rotating slots. The lifting blocks 31 are made of elastic material and can be made of plastic, rubber, or silicone to ensure friction between the lifting blocks 31 and the lifting slots 201. A lifting slope 311 is provided at the bottom of the lifting blocks 31. The lifting slope 311 is positioned toward the baking base 1. Rotating the drive ring 2 allows the inner wall of the lifting slot 201 to fit tightly against the lifting slope 311, thereby driving the lifting plate 3 in vertical motion.

[0050] Combine Figure 1 and Figure 4 The carrier plate 4 is placed on top of the lifting plate 3. The top of the carrier plate 4 is used to mount a container containing coffee beans. Two rotational engaging slots 301 are provided on the top of the lifting plate 3. The two rotational engaging slots 301 are distributed radially along the lifting plate 3. A rotational engaging rod 41 is fixedly mounted on the carrier plate 4. The rotational engaging rod 41 engages with the rotational engaging slots 301. The rotation of the engaging rod 41 and the rotational engaging slots 301 locks the rotation of the lifting plate 3 and the carrier plate 4. This allows the lifting plate 3, the carrier plate 4, and the container to move vertically when the driving plate rotates.

[0051] Reference Figure 2The coffee roaster also includes a heating plate 5, which is fixedly mounted to the roaster body and located on top of the carrier plate 4. The internal chamber of the heating plate 5 is equipped with a heating wire. When the coffee roaster is powered on, the heating wire releases heat, allowing the heating wire of the heating plate 5 to secondary burn combustible odor particles in the smoke generated during roasting. This reduces the odor of the smoke, making it less noticeable to users when using the coffee roaster. Furthermore, the roaster body is rotatably equipped with a shielding cover that covers the heating plate 5, preventing dust from sticking to the heating wire. This ensures the secondary combustion efficiency of the heating plate 5 and the odor removal effect of the smoke.

[0052] The coffee roaster of Example 1 of the present application employs the following principles: After mounting a container containing coffee beans on top of a carrier plate 4, the user secures the rotating clamping rod 41 with one hand and, with the other hand, rotates the drive ring 2 by rotating the drive rod 21. This causes the inner wall of the lifting groove 201 to abut against the lifting slope 311 at the bottom of the lifting block 31, thereby raising the container and causing the top of the container to abut against the bottom of the heating plate 5. Consequently, smoke is less likely to leak from the coffee roaster, making it less likely for the user to notice the unpleasant odor of the roasting smoke when using the coffee roaster, thereby improving the user experience.

[0053] Example 2:

[0054] The present embodiment discloses a coffee roaster, which includes all the technical features of the first embodiment and also includes the following technical features:

[0055] Reference Figure 5 、 Figure 6 as well as Figure 7 The shielding cover is rotatably coupled to the roaster body via a connecting assembly 6. The connecting assembly 6 includes a cover connector 61, a locking handle 62, and a cover rotating base 63. The cover connector 61 is a rectangular parallelepiped and is attached to the top of the roaster body via bolts. Two sliding slots 601 are defined within the cover connector 61, one on each side of the cover connector 61. A locking pin 611 slidably engages within the sliding slot 601. A resilient return spring 612 is positioned between the locking pin 611 and the inner wall of the sliding slot 601. In this embodiment, the return spring 612 is a linear spring, with its ends fixedly attached to the inner wall of the sliding slot 601 and the locking pin 611, respectively. A first magnet 613 is fixedly mounted within the locking pin 611, imparting magnetic properties to the locking pin 611.

[0056] The locking handle 62 is strip-shaped, and its middle portion pivotally engages with the cover connector 61. Two second magnets 621 are fixedly mounted on the locking handle 62, one at each end. This ensures that both ends of the locking handle 62 are magnetic, and the magnets at each end of the locking handle 62 attract the locking pins 611 toward it.

[0057] The top of the cover rotating seat 63 is provided with a cover rotating groove for allowing the shielding cover to rotate and engage with the cover rotating seat 63. The bottom of the cover rotating seat 63 is provided with two locking grooves, each corresponding to a locking pin 611. When the locking handle 62 is rotated toward the locking pin 611, the two locking pins 611 are respectively inserted into the locking holes 631, thereby attaching the shielding cover and the cover rotating seat 63 to the cover connecting seat 61. Furthermore, the cover connecting seat 61 is integrally connected to two guide plates 614. Both guide plates 614 extend in a vertical direction and fit snugly on either side of the cover rotating seat 63. This ensures that after the cover rotating seat 63 is attached to the cover connecting seat 61, the locking holes 631 are directly opposite the locking pins 611, thereby facilitating alignment and insertion of the locking pins 611 into the locking holes 631.

[0058] The implementation principle of a coffee roasting machine in Example 2 of the present application is as follows: Figure 8 When the heating wire of the heating plate 5 needs to be cleaned, the locking handle 62 is rotated and twisted so that the locking handle 62 rotates in a direction away from the locking pin 611, and then the locking pin 611 retracts from the locking hole 631 under the elastic force of the reset elastic member 612, so that the shielding cover and the cover rotating seat 63 can be quickly removed from the cover connecting seat 61, which is convenient and quick.

[0059] After cleaning the heating wire of the heating plate 5, the locking handle 62 is rotated and twisted so that the locking handle 62 rotates in the direction close to the locking pin 611, and then the locking pin 611 is attracted by the locking handle 62 through the magnetic force, and then the locking pin 611 is passed through the locking hole 631, so that the shielding cover and the cover rotating seat 63 are firmly installed on the cover connecting seat 61, which is convenient and quick.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
