Description

Technical Field

[0001] This disclosure relates to the technical field of coffee grinders, and in particular to a coffee bean feeding mechanism and a coffee grinder. Background Technology

[0002] Currently, as people's lives become increasingly richer, they are also more enthusiastic about drinking coffee. Making a cup of coffee requires grinding coffee beans into powder before brewing. In response to this need, many manufacturers have developed coffee grinders, which grind coffee beans to varying degrees to produce coffee powder.

[0003] However, most coffee grinders simply pour all the coffee beans into the hopper, allowing them to fall randomly during grinding. This random flow results in inconsistent bean quantities, leading to uneven grind size and negatively impacting the coffee's flavor. Therefore, a dedicated coffee bean feeding tool is urgently needed to complement the coffee grinder. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and to provide a coffee bean feeding mechanism and a coffee grinder that can evenly drop coffee beans.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A coffee bean feeding mechanism includes a housing assembly, a base, a bean separating plate, and a drive motor. The bottom of the housing assembly is connected to the end of the base. A bean separating plate is provided in the inner cavity of the housing assembly. The drive motor is installed in the inner cavity of the housing assembly and is located on the side of the bean separating plate adjacent to the base. The bean separating plate has a mounting hole. The power output end of the drive motor is connected to the bean separating plate through the mounting hole to drive the bean separating plate to rotate. The bean separating plate has a bean passing hole and is located on the other side of the bean separating plate away from the base. The base has a discharge port. A feeding pipe extends from the bean separating plate toward the base. The bean separating plate has a rotation port and a bean feeding port. The bean passing hole, the bean feeding port, the feeding pipe, and the discharge port are sequentially connected. The rotation shaft of the drive motor passes through the rotation port and is connected to the bean separating plate through the mounting hole.

[0007] In one embodiment, the housing assembly includes an upper housing and a lower housing, the bean divider is disposed in the inner cavity of the upper housing, the bottom of the upper housing is connected to the end of the lower housing, and the end of the lower housing is connected to the end of the base.

[0008] In one embodiment, the bottom wall of the lower housing is provided with a plurality of connecting pipes, each of the connecting pipes being spaced apart on the bottom wall of the lower housing, and the peripheral wall of the upper housing is provided with a plurality of connecting posts, each of the connecting posts being connected to one of the connecting pipes.

[0009] In one embodiment, the coffee bean feeding mechanism further includes a control board and a knob. The outer peripheral wall of the upper housing has a connecting hole. The power input shaft of the control board passes through the connecting hole and is connected to the knob. The control board is electrically connected to the drive motor.

[0010] In one embodiment, the bean-dividing plate is detachably connected to the rotating shaft of the drive motor.

[0011] In one embodiment, the bean-dividing plate has a connecting portion, the mounting through hole is formed in the connecting portion, and a magnetic attractor is embedded in the peripheral wall of the mounting through hole, the magnetic attractor being magnetically attracted to the rotating shaft of the drive motor.

[0012] In one embodiment, the bean separator plate has a mounting portion protruding from one side wall near the base, the connecting portion has a mounting opening, and the drive motor is fixedly mounted to the mounting opening.

[0013] In one embodiment, the coffee bean feeding mechanism further includes a connecting shaft, and the inner peripheral wall of the base is provided with a connecting groove; the lower housing is provided with a sliding opening at one end near the base, and the inner peripheral wall of the lower housing is provided with a sliding block; the first end of the connecting shaft is fixed to the connecting groove, and the second end of the connecting shaft passes through the sliding opening and is slidably connected to the sliding block.

[0014] In one embodiment, the coffee bean feeding mechanism further includes a magnetic suction plate, and a limiting part is provided at the center of the bottom of the base. The limiting part is used to install in the mounting cavity of the coffee grinder. The limiting part and the inner peripheral wall of the base together form a groove, and the magnetic suction plate is embedded in the groove.

[0015] A coffee grinder includes the coffee bean feeding mechanism described in any of the above embodiments.

[0016] Compared with the prior art, this disclosure has at least the following advantages:

[0017] The bottom of the housing assembly is connected to the end of the base. A bean separator is installed inside the housing assembly to separate coffee beans within the housing. The drive motor is installed inside the housing assembly, located on the side of the bean separator adjacent to the base, positioned above the base. A bean separator plate has a bean-passing hole and is located on the side of the bean separator away from the base, allowing the bean separator plate and drive motor to be positioned opposite each other on opposite sides of the bean separator plate. A mounting hole connects to a rotating port, allowing the drive motor's rotating shaft to pass through the rotating port and mounting hole of the bean separator plate and connect to the bean separator plate. When the drive motor's rotating shaft rotates, it causes the bean separator plate to rotate on one end face of the bean separator plate. Because the bean-passing hole of the bean separator plate, the bean outlet of the bean separator plate, the feeding pipe, and the outlet of the base are sequentially connected, coffee beans can fall sequentially through the bean-passing hole, the bean outlet, the feeding pipe, and the outlet, exiting the coffee bean feeding mechanism and connecting to the bean storage chamber of the external coffee grinder. When the drive motor rotates, its shaft is fixedly connected to the bean separator plate, causing the plate to rotate as well. During this rotation, the bean separator plate's feed holes align with the bean inlet, causing coffee beans to fall through the feed pipe and then to the outlet at the base. The drive motor's cyclical rotation of the bean separator plate on the separator plate repeatedly causes the feed holes and bean inlet to repeatedly overlap, further guiding the coffee beans from the bean inlet to the bottom of the separator plate, and then through the feed pipe and outlet. This ensures the coffee beans are evenly distributed into the grinder's hopper. The speed at which the feed holes and bottom of the separator plate align can be controlled by adjusting the drive motor's rotation speed, thus controlling the rate at which the coffee beans fall into the hopper.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] like Figures 1 to 4As shown, a coffee bean dispensing mechanism 10 of one embodiment includes a housing assembly 100, a base 200, a bean separating plate 300, and a drive motor 400. The bottom of the housing assembly 100 is connected to the end of the base 200, and a bean separating plate 1110 is provided in the inner cavity of the housing assembly 100. The drive motor 400 is installed in the inner cavity of the housing assembly 100, and the drive motor 400 is located on the side of the bean separating plate 1110 adjacent to the base 200. The bean separating plate 300 has a mounting through hole 3210, and the power output end of the drive motor 400 is connected to the bean separating plate 300 through the mounting through hole to drive the bean separating plate 300 to rotate. The bean separating plate 300 has bean passage holes 310. The bean separating plate 300 is located on the other side of the bean separating plate 1110 away from the base 200. The base 200 has a discharge port 210. The bean separating plate 1110 extends towards the base 200 and has a feeding pipe 130. The bean separating plate 1110 has a rotating port 1112 and a bean discharge port 1111. The bean passage holes 310, the bean discharge port 1111, the feeding pipe 130, and the discharge port 210 are connected in sequence. The rotating shaft of the drive motor 400 passes through the rotating port 1112 and is connected to the bean separating plate 300 through the mounting through hole 3210.

[0030] In this embodiment, the bottom of the housing assembly 100 is connected to the end of the base 200. A bean separator 1110 is provided inside the housing assembly 100 to separate coffee beans within the housing assembly 100. A drive motor 400 is installed inside the housing assembly 100 and located on the side of the bean separator 1110 adjacent to the base 200, placing the drive motor 400 above the base 200. A bean separating plate has bean holes 310 and is located on the other side of the bean separator 1110 away from the base 200, thus allowing the bean separating plate 300 and the drive motor 400 to be positioned opposite each other on either side of the bean separator 1110. The mounting hole 3210 is connected to the rotating port 1112, allowing the rotating shaft of the drive motor 400 to pass through the rotating port 1112 and the mounting hole 3210 of the bean separating plate 300 and connect to the bean separating plate 300. Therefore, when the rotating shaft of the drive motor 400 rotates, it can drive the bean separating plate 300 to rotate on one end face of the bean separating plate 1110. Because the bean passage hole 310 of the bean separating plate 300, the bean outlet 1111 of the bean separating plate 1110, the feeding pipe 130, and the discharge port 210 of the base 200 are sequentially connected, coffee beans can sequentially pass through the bean passage hole 310, the bean outlet 1111, the feeding pipe 130, and the discharge port 210, falling out of the coffee bean feeding mechanism 10 and into the bean storage chamber of the external coffee grinder. When the drive motor 400 rotates, because the rotating shaft of the drive motor 400 is fixedly connected to the bean separating plate 300, it will drive the bean separating plate 300 to rotate. When the bean separating plate 300 rotates, the bean passing hole 310 of the bean separating plate 300 overlaps with the bean outlet 1111 due to the rotation. As a result, the coffee beans on the bean separating plate 300 fall into the feeding pipe 130 and then into the discharge port 210 of the base 200. The drive motor 400 drives the bean separating plate 300 to rotate periodically on the bean separating plate 1110, causing the bean passage hole 310 to repeatedly overlap with the bean outlet 1111. This allows coffee beans to fall from the bean outlet 1111 into the bean outlet 1111 of the bean separating plate 1110, and then through the bean outlet 1111 into the feeding pipe 130 and the discharge port 210, ultimately reaching the bean storage bin of the external coffee grinder. This avoids the tedious operation of manually adding coffee beans to the bean bin. Furthermore, the speed at which the bean passage hole 310 of the bean separating plate 300 overlaps with the bean outlet 1111 of the bean separating plate 1110 can be controlled by the rotation speed of the drive motor 400, thereby controlling the speed at which the coffee beans fall into the bean storage bin.

[0031] It should be noted that the drive motor 400 is a conventional technology in this field, and will not be described in detail here.

[0032] like Figure 1As shown, in one embodiment, the housing assembly 100 includes an upper housing 110 and a lower housing 120. The bean-separating plate 1110 is disposed in the inner cavity of the upper housing 110. The bottom of the upper housing 110 is connected to the end of the lower housing 120, and the end of the lower housing 120 is connected to the end of the base 200. It can be understood that the housing assembly 100 is divided into an upper housing 110 and a lower housing 120, and the upper housing 110 and the lower housing 120 are fixedly connected to form the housing assembly 100. The bean separator 1110 is welded into the inner cavity of the upper housing 110 and is located in the middle of the inner cavity of the upper housing 110, thereby dividing the inner cavity of the upper housing 110 into two areas. The first area is used to place coffee beans, and the second area is used to install the drive motor 400 and set the feeding pipe 130. At the same time, the end of the lower housing 120 away from the upper housing 110 is connected to the end of the base 200, so that the housing assembly 100 can be fixedly connected to the base 200.

[0033] Combination Figure 3 and Figure 4 As shown, further, the bottom wall of the lower housing 120 is provided with a plurality of connecting pipes 1210, each of the connecting pipes 1210 being spaced apart from the bottom wall of the lower housing 120. The peripheral wall of the upper housing 110 is provided with a plurality of connecting posts 1120, each of the connecting posts 1120 being connected to one of the connecting pipes 1210. It can be understood that by providing a plurality of connecting pipes 1210 on the bottom wall of the lower housing 120, and by providing connecting posts 1120 on the peripheral wall of the upper housing 110, with each connecting post 1120 corresponding to one connecting pipe 1210, the upper housing 110 and the lower housing 120 are combined by connecting pipes 1210 and connecting posts 1120 in a corresponding snap-fit ​​manner. By designing multiple connecting pipes 1210 and connecting posts 1120 in a one-to-one correspondence, the assembly between the upper housing 110 and the lower housing 120 is thus stabilized.

[0034] Combination Figure 1 and Figure 4As shown, the coffee bean feeding mechanism 10 further includes a control board 500 and a knob 600. The outer peripheral wall of the upper housing 110 is provided with a connection hole 1130. The power input shaft of the control board 500 passes through the connection hole 1130 and is connected to the knob 600. The control board 500 is electrically connected to the drive motor 400. It is understood that a connection hole 1130 is provided on the outer peripheral wall of the upper housing 110. At the same time, the power input shaft of the control board 500 passes through the connection hole 1130 and is connected to the knob 600. The other end of the control board 500 is electrically connected to the drive motor 400. When the user needs to adjust the rotation speed of the bean dispensing plate 300, the control board 500 can control the power input of the drive motor 400 by turning the knob 600, thereby controlling the rotation speed of the bean dispensing plate 300 by the rotation shaft of the drive motor 400. This allows the rotation speed of the bean dispensing plate 300 to be controlled according to different needs by turning the knob 600, thereby changing the overlap rate of the bean outlet 1111 and the bean passage hole 310, and thus changing the bean dispensing rate. It is understandable that by controlling the overlap rate of the bean outlet 1111 and the bean passage 310, when the bean distribution plate 300 increases its rotation speed, the number of overlaps between the bean outlet 1111 and the bean passage 310 increases, thereby causing more coffee beans located on the bean distribution plate 300 to slide through the bean outlet 1111 to the feed port of the base 200.

[0035] like Figure 2 As shown, in one embodiment, the bean-dispensing plate 300 is detachably connected to the rotating shaft of the drive motor 400. It can be understood that the detachable connection of the bean-dispensing plate 300 to the rotating shaft of the drive motor 400 allows for the replacement of different specifications of the bean-dispensing plate 300 according to different user needs, optimizing different bean-dispensing precision and speed. Simultaneously, as the bean-dispensing plate 300 is a component that directly contacts the coffee beans, it is prone to accumulating oils and residues. The detachable design allows users to periodically remove the bean-dispensing plate 300 for deep cleaning, avoiding contamination of subsequent coffee beans and improving hygiene standards.

[0036] See Figure 1 and Figure 2 In one embodiment, the bean-dividing plate 300 has a protruding connecting portion 320, and the mounting through hole is formed in the connecting portion. A magnetic suction element is embedded in the peripheral wall 3210 of the mounting through hole, and the magnetic suction element is magnetically attracted to the rotating shaft of the drive motor 400. It can be understood that by having a connecting portion 320 protruding on one side wall of the bean-dividing plate 300 near the drive motor 400, and a mounting through hole formed in the inner cavity of the connecting portion, and a magnetic suction element embedded in the peripheral wall of the mounting through hole 3210, the rotating shaft of the drive motor 400 passes through the mounting through hole 3210 and is magnetically attracted to the magnetic suction element of the mounting through hole 3210. When it is necessary to disassemble the bean-dividing plate 300, it is only necessary to move the bean-dividing plate 300 away from the rotating shaft of the drive motor 400 to separate the bean-dividing plate 300.

[0037] See Figure 1 and Figure 3 As shown, in one embodiment, the bean separator 1110 has a protruding mounting portion 1113 on one side wall near the base 200. The mounting portion 1113 has a mounting opening 1113a, and the drive motor 400 is fixedly mounted in the mounting opening 1113a. It can be understood that the mounting portion 1113 protrudes from the side wall of the bean separator 1110 near the base 200, and the mounting portion 1113 has a mounting opening 1113a. The drive motor 400 is inserted into the mounting opening 1113a, thereby enabling the drive motor 400 to be stably fixed in the inner cavity of the housing assembly 100.

[0038] like Figure 2 As shown, in one embodiment, the coffee bean feeding mechanism 10 further includes a connecting shaft 700. The inner peripheral wall of the base 200 has a connecting groove 220. The lower housing 120 has a sliding opening 1220 near the end of the base 200. A sliding block 1230 protrudes from the inner peripheral wall of the lower housing 120. The first end of the connecting shaft 700 is fixedly connected to the connecting groove 220, and the second end of the connecting shaft 700 passes through the sliding opening 1220 and is slidably connected to the sliding block 1230. It can be understood that the connecting groove 220 is provided on the inner peripheral wall of the base 200, and the bottom of the lower housing 120 is located on the inner peripheral wall of the base 200. The first end of the connecting shaft 700 is fixedly connected to the connecting groove 220, and the second end of the connecting shaft passes through the sliding opening 1220 and slidably abuts against the sliding block 1230, allowing the lower housing 120 to slide left and right relative to the base 200 along the extending direction of the sliding block 1230. Furthermore, since the lower housing 120 is fixedly connected to the upper housing 110, when the lower housing 120 slides left and right, the upper housing 110 slides simultaneously, allowing the upper housing 110 to tilt at different angles according to different needs.

[0039] Combination Figure 1 and Figure 5As shown, in one embodiment, the coffee bean dispensing mechanism 10 further includes a magnetic suction plate 800. A limiting portion 230 protrudes from the center of the bottom of the base 200. The limiting portion 230 is used to install into the mounting cavity of the coffee grinder. The limiting portion 230 and the inner peripheral wall of the base 200 together form a groove 240, and the magnetic suction plate 800 is embedded in the groove 240. It can be understood that the limiting portion 230 protrudes from the top of the base 200, and the limiting portion 230 can be connected to the mounting cavity of the external coffee grinder, making the coffee grinder and the coffee bean dispensing mechanism 10 an integrated device, thereby enabling the coffee bean dispensing mechanism 10 to dispense beans from the coffee grinder's bean storage compartment. Meanwhile, a groove 240 is formed by the inner peripheral wall of the limiting part 230 and the base 200. The magnetic plate 800 is embedded in the groove 240, so that the magnetic plate 800 can be magnetically fixed to the wall of the coffee grinder, thereby stabilizing the connection between the coffee bean feeding mechanism 10 and the coffee grinder.

[0040] This application also includes a coffee grinder, comprising the coffee bean feeding mechanism 10 described in any of the above embodiments. It is understood that in the coffee grinder, the drive motor 400 drives the bean separating plate 300 to rotate periodically on the bean separating plate 1110, causing the bean passage hole 310 to repeatedly overlap with the bean feeding port 1111. This allows coffee beans to fall from the bean feeding port 1111 onto the bean feeding port 1111 of the bean separating plate 1110, and then through the bean feeding port 1111 to the feeding pipe 130 and the discharge port 210, ultimately reaching the bean storage bin of the external coffee grinder. This avoids the tedious manual addition of coffee beans to the bean storage bin, and the speed at which the bean passage hole 310 of the bean separating plate 300 overlaps with the bean feeding port 1111 of the bean separating plate 1110 can be controlled by adjusting the rotation speed of the drive motor 400, thereby controlling the speed at which the coffee beans fall into the bean storage bin.

[0041] Compared with the prior art, this disclosure has at least the following advantages:

[0042] The bottom of the housing assembly 100 is connected to the end of the base 200. A bean separator 1110 is provided inside the housing assembly 100 to separate coffee beans within the housing assembly 100. A drive motor 400 is installed inside the housing assembly 100 and located on the side of the bean separator 1110 adjacent to the base 200, placing the drive motor 400 above the base 200. A bean separating plate has bean holes 310 and is located on the other side of the bean separator 1110 away from the base 200, thus positioning the bean separating plate 300 and the drive motor 400 opposite each other on either side of the bean separator 1110. The mounting hole 3210 is connected to the rotating port 1112, allowing the rotating shaft of the drive motor 400 to pass through the rotating port 1112 and the mounting hole 3210 of the bean separating plate 300 and connect to the bean separating plate 300. Therefore, when the rotating shaft of the drive motor 400 rotates, it can drive the bean separating plate 300 to rotate on one end face of the bean separating plate 1110. Because the bean passage hole 310 of the bean separating plate 300, the bean outlet 1111 of the bean separating plate 1110, the feeding pipe 130, and the discharge port 210 of the base 200 are sequentially connected, coffee beans can sequentially pass through the bean passage hole 310, the bean outlet 1111, the feeding pipe 130, and the discharge port 210, falling out of the coffee bean feeding mechanism 10 and into the bean storage chamber of the external coffee grinder. When the drive motor 400 rotates, because the rotating shaft of the drive motor 400 is fixedly connected to the bean separating plate 300, it will drive the bean separating plate 300 to rotate. When the bean separating plate 300 rotates, the bean passing hole 310 of the bean separating plate 300 overlaps with the bean outlet 1111 due to the rotation. As a result, the coffee beans on the bean separating plate 300 fall into the feeding pipe 130 and then into the discharge port 210 of the base 200. The drive motor 400 drives the bean separating plate 300 to rotate periodically on the bean separating plate 1110, causing the bean passage hole 310 to repeatedly overlap with the bean outlet 1111. This allows coffee beans to fall from the bean outlet 1111 into the bean outlet 1111 of the bean separating plate 1110, and then through the bean outlet 1111 into the feeding pipe 130 and the discharge port 210, ultimately reaching the bean storage bin of the external coffee grinder. This avoids the tedious operation of manually adding coffee beans to the bean bin. Furthermore, the speed at which the bean passage hole 310 of the bean separating plate 300 overlaps with the bean outlet 1111 of the bean separating plate 1110 can be controlled by the rotation speed of the drive motor 400, thereby controlling the speed at which the coffee beans fall into the bean storage bin.

[0043] 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.
