Description

Technical Field

[0001] This disclosure relates to the technical field of coffee machines, and in particular to a coffee brewing mechanism and a coffee machine. Background Technology

[0002] Currently, with the continuous improvement of people's living standards, their interest in coffee and tea is also rising. Because people prefer to use automatic coffee makers to brew coffee, many businesses have developed various coffee and tea brewing machines to meet this demand.

[0003] For example, Chinese patent document CN117860112A describes a spiral drive mechanism and a spiral watering fully automatic coffee machine. The spiral drive mechanism includes a water outlet pipe, a first rotating mechanism, and a first lifting mechanism. The first rotating mechanism includes a mounting bracket, a rotating base, a rotating platform, a rotating wheel, and a rotating drive assembly. The water outlet pipe is oscillatingly mounted on the rotating base. The rotating base, rotating platform, and rotating wheel are arranged in parallel, and the rotating base and rotating wheel are connected by a rotating drive rod. The rotating platform is slidably mounted on the rotating drive rod. The rotating drive assembly is connected to the rotating base or rotating wheel via a transmission connection. A connecting rod is provided between the water outlet pipe and the rotating platform, and the first lifting mechanism is connected to the rotating platform.

[0004] However, although the aforementioned spiral drive mechanism and spiral watering fully automatic coffee machine achieve the spiral watering brewing effect by swinging the water outlet pipe through the first rotating mechanism and the first lifting mechanism, and because the lifting motor drives the bracket to move up and down through the lifting gear and rack, thereby causing the water outlet pipe to swing, the lifting motor drives the bracket to move up and down through the lifting gear and rack for a long time during the brewing function of the coffee machine. Under long-term operation, the lifting gear and rack will rotate due to friction. The long-term friction and rotation will cause wear on the lifting mechanism. As a result, the lifting mechanism becomes structurally unstable during operation, and the bracket driven by the lifting mechanism to swing the water outlet pipe is unstable due to structural wear. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and to provide a coffee brewing mechanism and coffee machine that prevents excessive wear and tear on the drive mechanism due to prolonged operation.

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

[0007] A coffee brewing mechanism includes a support, a tank, and a water outlet pipe. The tank is mounted on the support, and the water outlet pipe passes through the inner cavity of the tank. The water inlet of the water outlet pipe is connected to an external water source.

[0008] The coffee brewing mechanism also includes:

[0009] Rotating component;

[0010] Drive frame;

[0011] The system includes a pushing component and a swing disk. The tank body has an installation cavity, and the swing disk is movably connected to the inner wall of the installation cavity. Both the rotating component and the pushing component are mounted on a bracket. The power output end of the rotating component is fixedly connected to the tank body, and the rotating component drives the tank body to rotate. The swing disk has a through hole, and the water outlet pipe passes through the installation cavity and the through hole sequentially from top to bottom. The drive frame is slidably disposed on the inner wall of the installation cavity. The power output end of the pushing component is connected to the drive frame, and the abutting end of the drive frame abuts against the end face of the swing disk. The position of the abutting end of the drive frame abutting against the swing disk is offset from the swing center of the swing disk. The pushing component drives the drive frame to slide relative to the tank body within the installation cavity.

[0012] In one embodiment, the rotating assembly further includes a rotating driver, a first rotating gear, and a second rotating gear. The rotating driver is fixed to the bracket, and the rotating shaft of the rotating driver is connected to the first rotating gear. The first rotating gear and the second rotating gear are mounted on the end face of the bracket. The first rotating gear is connected to the second rotating gear, and the second rotating gear is connected to the tank.

[0013] In one embodiment, the outer periphery of the drive frame is provided with an anti-slip part, the center of the second rotating gear is provided with a receiving groove, the second rotating gear is also provided with a sliding groove opening that communicates with the receiving groove, and the anti-slip part is located in the sliding groove opening and is slidably connected to the second rotating gear.

[0014] In one embodiment, the pushing assembly includes a pushing driver and an eccentric wheel, the rotating shaft of the pushing driver is fixedly connected to the eccentric position of the eccentric wheel, and the outer periphery of the eccentric wheel abuts against the end face of the driving frame.

[0015] In one embodiment, an outer boss is provided on the outer periphery of the drive frame, the outer boss is located at the end of the drive frame away from the eccentric wheel, and the outer boss is slidably limited within the mounting cavity.

[0016] In one embodiment, the drive frame includes a frame body and a push column. The frame body is sleeved on the inner peripheral wall of the tank and slidably connected to the tank. The push column is located on the side of the frame body near the swing disk and is connected to the frame body. The abutting end of the push column abuts against the end face of the swing disk.

[0017] In one embodiment, the coffee brewing mechanism further includes a rotating shaft, the tank has a rotating opening, and the rotating shaft movably passes through the rotating opening and is connected to the outer peripheral wall of the oscillating disc.

[0018] In one embodiment, the coffee brewing mechanism further includes a deflection control element mounted on the bracket and electrically connected to the control terminal of the drive driver. The deflection control element is used to control the angular displacement of the power output terminal of the drive driver.

[0019] In one embodiment, the coffee brewing mechanism further includes an elastic element disposed within the mounting cavity, one end of which abuts against the drive frame, and the other end of which abuts against the end face of the oscillating disk.

[0020] A coffee machine comprising the coffee brewing mechanism described in any of the above embodiments.

[0021] Compared with the prior art, this disclosure has at least the following advantages:

[0022] By passing the outlet pipe through the inner cavity of the tank and connecting its inlet end to an external water source, the outlet pipe can have a flowing water supply after being connected to the external water source. An installation cavity is provided inside the tank, and a swing plate is movably connected to the inner wall of the installation cavity. A through hole is provided on the swing plate. The outlet pipe passes through the installation cavity and the through hole sequentially from top to bottom, so that the outlet pipe first passes through the installation cavity of the tank and then through the through hole to pass through the swing plate. Furthermore, because the tank is mounted on a bracket, and the rotating component is mounted on the bracket, with the power output end of the rotating component fixedly connected to the tank, when the rotating component... When the rotating shaft rotates, the rotating assembly, connected to the tank, causes the tank to rotate circumferentially. Furthermore, because the swing disk is movably connected to the inner wall of the mounting cavity, the swing disk can swing left and right within the tank. Simultaneously, the power output end of the pushing assembly is connected to the drive frame, and the abutting end of the drive frame abuts against the end face of the swing disk. Because the drive frame is slidably mounted on the inner wall of the mounting cavity, when the power output end of the pushing assembly acts on the drive frame, the drive frame slides within the mounting cavity, causing the abutting end of the drive frame to abut against the end face of the swing disk, thus causing the swing disk to swing left and right within the mounting cavity. Furthermore, when the rotating component drives the tank to rotate, the water outlet pipe passing through the tank and the rotating disk will undergo a spiral motion. At the same time, when the pushing component pushes the drive frame to oscillate the swing disk left and right, the water outlet pipe will swing left and right. When the pushing component and the rotating component work simultaneously, the water outlet pipe can deflect left and right and rotate, thereby enabling the water outlet pipe to achieve spiral, circular and straight watering modes. The pushing component is installed on the bracket, and the power output end of the pushing component acts on the drive frame, causing the drive frame to slide on the inner wall of the tank's mounting cavity. Then, the abutting end of the drive frame drives the swing disk to swing. This avoids the drive method of using lifting gears and racks to drive the drive frame to move up and down, and avoids the wear and tear of the lifting mechanism caused by long-term friction rotation.

[0031] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0032] like Figures 1 to 2As shown, a coffee brewing mechanism 10 according to one embodiment includes a support 100, a container 200, a water outlet pipe 300, a rotating assembly 400, a drive frame 500, a pushing assembly 600, and a swing plate 700. The container 200 is mounted on the support 100, and the water outlet pipe 300 passes through the inner cavity of the container 200, with its water inlet end connected to an external water source. The container 200 has an installation cavity 210, and the swing plate 700 is movably connected to the inner wall of the installation cavity 210. The rotating assembly 400 and the pushing assembly 600 are both mounted on the support 100, and the power output end of the rotating assembly 400 is fixedly connected to the container 200. The rotating component 400 is used to drive the tank 200 to rotate; the swing disk 700 has a through hole 710, and the water outlet pipe 300 passes through the mounting cavity 210 and the through hole 710 sequentially from top to bottom; the drive frame 500 is slidably disposed on the inner wall of the mounting cavity 210, the power output end of the pushing component 600 is connected to the drive frame 500, the abutting end of the drive frame 500 abuts against the end face of the swing disk 700, and the position of the abutting end of the drive frame abutting against the swing disk is offset from the swing center of the swing disk; the pushing component 600 is used to drive the drive frame 500 to slide relative to the tank 200 in the mounting cavity 210.

[0033] In this embodiment, the water outlet pipe 300 passes through the inner cavity of the tank 200, and the water inlet end of the water outlet pipe 300 is connected to an external water source, so that the water outlet pipe 300 can have a flowing water source after being connected to the external water source. An installation cavity 210 is provided inside the tank 200, and the swing disk 700 is movably connected to the inner wall of the installation cavity 210. A through hole 710 is provided in the swing disk 700. The water outlet pipe 300 passes through the installation cavity 210 and the through hole 710 sequentially from top to bottom, so that the water outlet pipe 300 first passes through the installation cavity 210 of the tank 200, and then passes through the through hole 710 to the swing disk 700. Furthermore, since the tank 200 is mounted on the bracket 100, and the rotating component 400 is mounted on the bracket 100, and the power output end of the rotating component 400 is fixedly connected to the tank 200, When the rotating shaft of the rotating component 400 rotates, the rotating component 400, connected to the tank 200, causes the tank 200 to rotate circumferentially. Furthermore, because the swing disk 700 is movably connected to the inner wall of the mounting cavity 210, the swing disk 700 can swing left and right within the inner cavity of the tank 200. At the same time, the power output end of the pushing component 600 is connected to the drive frame 500, and the abutting end of the drive frame 500 abuts against the end face of the swing disk 700. Because the drive frame 500 is slidably disposed on the inner wall of the mounting cavity, when the power output end of the pushing component 600 acts on the drive frame 500, the drive frame 500 will slide within the mounting cavity 210, thereby causing the abutting end of the drive frame 500 to abut against the end face of the swing disk 700, causing the swing disk 700 to swing left and right within the mounting cavity 210. Furthermore, when the rotating component 400 drives the tank 200 to rotate, the water outlet pipe 300 passing through the tank 200 and the rotating disk will perform a spiral motion. At the same time, when the pushing component 600 pushes the drive frame 500 to swing the swing disk 700 left and right, the water outlet pipe 300 will swing left and right. When the pushing component 600 and the rotating component work at the same time, the water outlet pipe 300 can perform left and right offset and rotational movements, thereby enabling the water outlet pipe 300 to achieve spiral, circular and straight watering modes. The pushing component 600 is installed on the bracket 100, and the power output end of the pushing component 600 acts on the drive frame 500, so that the drive frame 500 slides on the inner wall of the mounting cavity 210 of the tank 200. Then, the abutting end of the drive frame 500 drives the swing disk 700 to swing. This avoids the driving method of driving the drive frame 500 to move up and down through the lifting gear and rack, and avoids the wear and tear of the lifting mechanism caused by long-term friction rotation.

[0034] like Figure 1As shown, the rotating assembly 400 further includes a rotating driver 410, a first rotating gear 420, and a second rotating gear 430. The rotating shaft 220 of the rotating driver 410 is connected to the first rotating gear 420. The first rotating gear 420 and the second rotating gear 430 are mounted on the end face of the bracket 100. The first rotating gear 420 is connected to the second rotating gear 430, and the second rotating gear 430 is connected to the tank 200. It can be understood that the rotating shaft 220 of the rotating drive 410 is connected to the first rotating gear 420, causing the first rotating gear 420 to rotate. Since the second rotating gear 430 is meshed with the first rotating gear 420 and connected to the tank 200, when the first rotating gear 420 drives the second rotating gear 430 to rotate, the second rotating gear 430 drives the tank 200 to rotate. Since the swing disk 700 is set in the inner cavity of the tank 200, it further drives the water outlet pipe 300 passing through the rotating disk to rotate, thereby realizing the spiral water outlet method of the water outlet pipe 300.

[0035] Combination Figure 1 and Figure 2 As shown, in one embodiment, the outer periphery of the drive frame 500 is provided with an anti-slip portion 510, the center of the second rotating gear 430 is provided with a receiving groove, and the second rotating gear 430 is also provided with a sliding groove opening 4310 communicating with the receiving groove. The anti-slip portion 510 is located in the sliding groove opening 4310 and is slidably connected to the second rotating gear 430. Further, a receiving cavity 4320 is provided in the center of the second rotating gear 430, so that the drive frame 500 passes through the receiving cavity 4320. At the same time, the second rotating gear 430 is provided with a sliding groove opening 4310, and the anti-slip portion 510 is located in the sliding groove opening 4310 and is slidably connected to the second rotating gear 430, so that the second rotating gear 430 can drive the drive frame 500 to rotate through the anti-slip portion 510.

[0036] like Figure 1As shown, in one embodiment, the pushing assembly 600 includes a push driver 610 and an eccentric wheel 620. The rotation shaft 220 of the push driver 610 is fixedly connected to the eccentric position of the eccentric wheel 620, and the outer periphery of the eccentric wheel 620 abuts against the end face of the drive frame 500. It can be understood that the eccentric wheel 620 is directly driven to rotate by the rotation shaft of the push driver 610, utilizing the asymmetric contour characteristics of the eccentric wheel 620 to convert the rotational motion into the reciprocating linear motion of the drive frame 500. Specifically, when the push driver 610 is activated, the eccentric wheel 620 rotates around its axis. Since the outer periphery of the eccentric wheel 620 maintains dynamic contact with the end face of the drive frame 500, the radial offset generated during its rotation is transmitted to the drive frame 500 through the contact point, forcing the drive frame 500 to slide periodically along the inner wall of the mounting cavity 210. This transmission method eliminates the need for gear meshing or lead screw structures, effectively reducing the mechanical losses of the transmission chain.

[0037] In the above embodiments, the push driver and the rotation driver can be stepper motors.

[0038] See Figure 1 and Figure 3 Furthermore, the outer periphery of the drive frame 500 is provided with an outer protrusion 540, which is located at the end of the drive frame 500 away from the eccentric wheel 620. The outer protrusion 540 is slidably limited within the mounting cavity 210. It can be understood that by setting the outer protrusion 540 on the outer periphery of the bottom of the drive frame 500, the end of the tank 200 abuts against the outer protrusion 540. Further, the drive frame 500 is fitted into the mounting cavity 210 of the tank 200, allowing the drive frame 500 to slide against the inner wall of the mounting cavity 210. Because the outer protrusion 540 and the tank 200 abut against each other, the drive frame 500 is prevented from detaching from the mounting cavity 210 of the tank 200 during movement.

[0039] like Figure 1As shown, in another embodiment, the drive frame 500 includes a frame body 520 and a push column 530. The frame body 520 is sleeved on the inner peripheral wall of the tank 200, and the push column 530 is located on the side of the frame body 520 near the swing disk 700. The push column 530 is connected to the frame body 520, and the abutting end of the push column 530 abuts against the end face of the swing disk 700. In this embodiment, the drive frame 500 is decomposed into a combined structure of the frame body 520 and the push column 530. Radial positioning is achieved through the sleeve engagement between the frame body 520 and the inner wall of the tank 200, while the push column 530 serves as an independent power transmission unit that contacts the swing disk 700. Specifically, the frame body 520 adopts a ring frame structure, and its inner peripheral wall forms a clearance fit with the inner peripheral wall of the mounting cavity 210 of the tank 200, allowing the frame body 520 to slide smoothly along the axial direction of the tank 200; the push column 530 abuts against the end face of the frame body 520 facing the swing disk 700 at an inclined angle. When the frame body 520 slides downward in the inner cavity of the tank 200, the push column 530 abuts against the swing disk 700, thereby causing the swing disk 700 to swing left and right in the inner cavity of the tank 200.

[0040] Combination Figure 1 and Figure 3 As shown, in one embodiment, the coffee brewing mechanism 10 further includes a rotating shaft 220. The container 200 has a rotating opening 230, and the rotating shaft 220 movably passes through the rotating opening 230 and is connected to the outer peripheral wall of the oscillating disk 700. It can be understood that the dynamic cooperation between the rotating shaft 220 and the oscillating disk 700 provides the oscillating disk 700 with both rotational freedom and radial support. Specifically, the rotating shaft 220 movably passes through the rotating opening 230, allowing it to rotate within the opening. Simultaneously, one end of the rotating shaft 220 is fixedly connected to the oscillating disk 700, so that when the rotating shaft 220 rotates within the rotating opening 230, the end of the rotating shaft 220, threadedly connected to the oscillating disk, further drives the oscillating disk to oscillate.

[0041] See Figure 3In one embodiment, the coffee brewing mechanism 10 further includes a deflection control component 800, which is mounted on the bracket 100 and electrically connected to the control terminal of the drive driver 610. The deflection control component 800 is used to control the angular displacement of the power output terminal of the drive driver 610. It can be understood that by introducing a digital deflection control component, the dynamic rotation angle of the eccentric wheel 620 is achieved. Specifically, the deflection control component 800 includes an angle encoder and a servo control module. The detection end of the angle encoder is non-contactly connected to the shaft of the eccentric wheel 620 via magnetic coupling, acquiring the instantaneous angular displacement signal of the eccentric wheel 620 in real time. The servo control module, based on a preset program or user input commands, converts the angle deviation value into a pulse signal and outputs it to the drive driver 610, thereby precisely controlling the eccentric wheel 620 to stop at any angle. When the rotating disk swings away from the preset position, the deflection control unit 800 controls the drive driver 610 to change the rotation speed of the eccentric wheel 620, thereby changing the pushing direction of the drive frame 500, so that the swing disk 700 can change the swing angle according to the rotation speed of the eccentric wheel 620.

[0042] like Figure 1 As shown, the coffee brewing mechanism 10 further includes an elastic element 900, which is disposed within the mounting cavity 210. One end of the elastic element 900 abuts against the drive frame 500, and the other end abuts against the end face of the oscillating disk 700. In this embodiment, the elastic element 900 can be a rubber spring or a coil spring. Because one end of the elastic element 900 abuts against the drive frame 500 and the other end of the elastic element 900 abuts against the end face of the oscillating disk 700, when the drive driver 610 stops working, the elastic element 900 will release elastic stress, thereby causing the drive frame 500 to return to its initial position.

[0043] This application also includes a coffee machine, including the application name described in any of the above embodiments. It is understood that by mounting the push assembly 600 on the bracket 100, and simultaneously using the power output end of the push assembly 600 to act on the drive frame 500, the drive frame 500 slides within the mounting cavity 210 of the tank 200. Then, the abutting end of the drive frame 500 drives the swing disk 700 to swing. This avoids the drive method of using lifting gears and racks to move the drive frame 500 up and down, thus preventing wear and tear on the lifting mechanism due to prolonged frictional rotation.

[0044] Compared with the prior art, this disclosure has at least the following advantages:

[0045] By passing the water outlet pipe 300 through the inner cavity of the tank body 200, and connecting the water inlet end of the water outlet pipe 300 to an external water source, the water outlet pipe 300 can have a flowing water source after being connected to the external water source. An installation cavity 210 is provided inside the tank body 200, and the swing plate 700 is movably connected to the inner wall of the installation cavity 210. A through hole 710 is provided in the swing plate 700. The water outlet pipe 300 passes through the installation cavity 210 and the through hole 710 sequentially from top to bottom, so that the water outlet pipe 300 first passes through the installation cavity 210 of the tank body 200, and then passes through the through hole 710 to the swing plate 700. Furthermore, because the tank body 200 is mounted on the bracket 100, and the rotating component 400 is mounted on the bracket 100, with the power output end of the rotating component 400 fixedly connected to the tank body 200, this allows for... When the rotating shaft of the rotating assembly 400 rotates, the rotating assembly 400, connected to the tank 200, causes the tank 200 to rotate circumferentially. Furthermore, because the swing disk 700 is movably connected to the inner wall of the mounting cavity 210, the swing disk 700 can swing left and right within the inner cavity of the tank 200. At the same time, the power output end of the pushing assembly 600 is connected to the drive frame 500, and the abutting end of the drive frame 500 abuts against the end face of the swing disk 700. Because the drive frame 500 is slidably disposed on the inner wall of the mounting cavity, when the power output end of the pushing assembly 600 acts on the drive frame 500, the drive frame 500 will slide within the mounting cavity 210, thereby causing the abutting end of the drive frame 500 to abut against the end face of the swing disk 700, causing the swing disk 700 to swing left and right within the mounting cavity 210. Furthermore, when the rotating component 400 drives the tank 200 to rotate, the water outlet pipe 300 passing through the tank 200 and the rotating disk will perform a spiral motion. At the same time, when the pushing component 600 pushes the drive frame 500 to swing the swing disk 700 left and right, the water outlet pipe 300 will swing left and right. When the pushing component 600 and the rotating component work at the same time, the water outlet pipe 300 can perform left and right offset and rotational movements, thereby enabling the water outlet pipe 300 to achieve spiral, circular and straight watering modes. The pushing component 600 is installed on the bracket 100, and the power output end of the pushing component 600 acts on the drive frame 500, so that the drive frame 500 slides on the inner wall of the mounting cavity 210 of the tank 200. Then, the abutting end of the drive frame 500 drives the swing disk 700 to swing. This avoids the driving method of driving the drive frame 500 to move up and down through the lifting gear and rack, and avoids the wear and tear of the lifting mechanism caused by long-term friction rotation.

[0046] 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 utility model 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.
