[0001] This utility model relates to the field of coffee machine technology, specifically to a coffee machine bean feeding assembly. Background Technology

[0002] The coffee bean dispenser assembly is a key component in a coffee machine responsible for the quantitative delivery and dispensing of coffee beans. Its performance directly affects the coffee brewing effect and user experience. Each bean dispensing chamber alternately connects to the feed hopper and the bean collection chamber to improve bean loading efficiency. However, existing coffee machine bean dispensing assemblies have some shortcomings, such as:

[0003] Application No.: CN202411325610.9 describes a coffee machine bean hopper grinding mechanism. This device is less prone to bean jamming and grinder splattering. The bean hopper assembly is easy to assemble and disassemble. In particular, the fit and fixing method between the bean hopper assembly and the bean hopper seat assembly, and between the bean hopper seat assembly and the grinder assembly, is stable. The machine only starts working after the bean hopper assembly is precisely in place. However, in actual use, during the feeding process, coffee beans may rush into the feeding hole, which may cause the feeding hole to become blocked.

[0004] Therefore, we propose a coffee bean feeding component for coffee machines to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a coffee bean feeding component for a coffee machine, in order to solve the problem mentioned in the background art that coffee beans are prone to rushing in and clogging the feeding hole during the feeding process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coffee machine bean feeding assembly, comprising a coffee machine body and a storage bin installed on the top of the coffee machine body, wherein a device bin is provided at the bottom of the storage bin, and a grinding bin is installed at the bottom of the device bin;

[0007] The device chamber is equipped with a drive mechanism, and the top of the drive mechanism is connected to a feeding mechanism. The feeding mechanism includes a bean feeding plate, the top of the bean feeding plate is equipped with an auger shaft, the top of the auger shaft is equipped with a scraper, and the auger shaft and scraper are located inside the storage chamber. The bottom of the storage chamber is equipped with a bean feeding bin, and the bean feeding plate is located inside the bean feeding bin. The bottom of the bean feeding bin is equipped with a transmission pipe, and the bottom of the transmission pipe is connected to the grinding chamber pipe.

[0008] The drive motor drives the feeding mechanism, which allows the coffee beans inside the storage bin to be transported to the feeding hole at the bottom of the storage bin by the auger shaft. This prevents all the coffee beans inside the storage bin from rushing into the feeding hole. At the same time, the feeding plate rotates in the feeding bin, dividing the space in the feeding bin into several chambers. The feeding plate then rotates to push the coffee beans into the transmission tube for metered feeding. This prevents the coffee beans from clogging during the feeding process.

[0009] As a preferred technical solution of this utility model, a material discharge hole is provided at the bottom left end of the storage bin, and a bean discharge hole is provided at the right end of the bean discharge bin. The bean discharge bin is connected to the transmission pipe through the bean discharge hole, and the bottom of the bean discharge bin is connected to the device bin.

[0010] The above technical solution enables a more secure connection between the bean feeder and the grinding chamber, allowing coffee beans to flow into the grinding chamber through the delivery tube.

[0011] As a preferred technical solution of this utility model, the device compartment is connected to the drive mechanism, and the drive mechanism includes a drive motor, and the drive motor is fixedly connected to the coffee machine body. The left end of the drive motor is provided with a first bevel gear, and the top of the first bevel gear meshes with a second bevel gear, and the top of the second bevel gear is fixedly connected to the lower bean plate.

[0012] The above technical solution enables the drive mechanism to be more stable when driving the feeding mechanism and the grinding mechanism, thereby increasing the stability of the equipment during operation.

[0013] As a preferred technical solution of this utility model, the bottom of the first bevel gear meshes with the third bevel gear, and the bottom of the third bevel gear is connected to the grinding mechanism. The grinding mechanism includes a grinding shaft, which is in contact with the inner wall of the grinding chamber. The bottom of the grinding chamber is provided with a filter chamber, and the bottom of the grinding shaft is provided with a crushing shaft, which is located inside the filter chamber.

[0014] The above technical solution enables coffee beans to be ground into powder in the grinding chamber through the grinding shaft and grinding chamber and then transported to the filter chamber, so that the filter chamber can intercept larger powder particles.

[0015] As a preferred technical solution of this utility model, the bottom of the grinding chamber is provided with a feeding hole, and the bottom of the grinding chamber is detachably connected to the filter chamber, and a filter screen is provided inside the filter chamber.

[0016] The above technical solution makes it easier for users to clean the filter chamber and filter screen, thus increasing the ease of cleaning the equipment.

[0017] As a preferred technical solution of this utility model, the filter chamber is fixedly connected to the filter screen, the top of the filter screen is in contact with the grinding shaft, and the coffee bean powder on the top of the filter screen can be scraped off when the grinding shaft rotates.

[0018] The above technical solution enables the grinding shaft to further grind the fallen soybean powder, and can scrape off the soybean powder from the surface of the filter screen, thereby avoiding clogging of the filter pores.

[0019] As a preferred technical solution of this utility model, a heating box is connected to the bottom of the filter chamber, and the interior of the coffee machine body is connected to the heating box. A liquid injection pipe is connected to the top of the heating box, and the liquid injection pipe is connected to the top of the coffee machine body.

[0020] The above technical solution enables the grinding mechanism to transfer the coffee bean powder to the heating chamber after grinding or filtering, thereby completing the bean feeding process and increasing the stability of the equipment during operation.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by driving the feeding mechanism with a drive motor, the coffee beans inside the storage bin can be transported to the feeding hole at the bottom of the storage bin under the drive of the auger shaft, which avoids all the coffee beans inside the storage bin flowing into the feeding hole. At the same time, the feeding plate will also rotate in the feeding bin, thereby dividing the space in the feeding bin into several cavities. Then the feeding plate will rotate to push the coffee beans into the transmission tube for quantitative feeding, which can prevent coffee bean blockage during the feeding process.

[0022] Furthermore, by setting up the grinding mechanism, when coffee beans enter the grinding chamber and are ground into bean powder, the grinding shaft can work with the grinding chamber to grind the beans and then transfer them to the filter chamber, which can intercept larger powder particles.

[0023] Furthermore, by ensuring that the bottom of the grinding shaft fits into the filter screen, the grinding shaft can further grind the fallen soybean powder, scraping off the soybean powder from the surface of the filter screen, thus preventing the filter pores from becoming clogged.

The feeding mechanism includes a bean-feeding plate 8, the top of the bean-feeding plate 8 is equipped with an auger shaft 9, and the top of the auger shaft 9 is equipped with a scraper 10. The auger shaft 9 and the scraper 10 are located inside the storage chamber 2. The bottom of the storage chamber 2 is equipped with a bean-feeding bin 11, and the bean-feeding plate 8 is located inside the bean-feeding bin 11. The bottom of the bean-feeding bin 11 is equipped with a transmission pipe 12, and the bottom of the transmission pipe 12 is connected to the grinding chamber 4.

[0034] The storage bin 2 has a discharge hole at the bottom left end, and the bean hopper 11 has a bean discharge hole at the right end. The bean hopper 11 is connected to the transmission pipe 12 through the bean discharge hole, and the bottom of the bean hopper 11 is connected to the device bin 3.

[0035] The device compartment 3 is connected to the drive mechanism, and the drive mechanism includes a drive motor 5. The drive motor 5 is fixedly connected to the coffee machine body 1. The left end of the drive motor 5 is provided with a first bevel gear 6, and the top of the first bevel gear 6 is meshed with a second bevel gear 7. The top of the second bevel gear 7 is fixedly connected to the lower bean plate 8.

[0036] The bottom of the first bevel gear 6 meshes with the third bevel gear 13, and the bottom of the third bevel gear 13 is connected to the grinding mechanism. The grinding mechanism includes a grinding shaft 14, which is in contact with the inner wall of the grinding chamber 4. The bottom of the grinding chamber 4 is provided with a filter chamber 16, and the bottom of the grinding shaft 14 is provided with a crushing shaft 15, which is located inside the filter chamber 16.

[0037] The bottom of the grinding chamber 4 is provided with a feeding hole, and the bottom of the grinding chamber 4 is detachably connected to the filter chamber 16. The filter chamber 16 is provided with a filter screen 17, and the filter screen 17 is fixedly connected to the inside of the filter chamber 16.

[0039] Working principle: When using the coffee bean feeding assembly of this coffee machine, first connect the power supply of the device to the power grid, and then drive the feeding mechanism to run, so that the feeding plate 8 and the auger shaft 9 rotate simultaneously. The auger shaft 9 will cooperate with the scraper 10 to make the coffee beans inside the storage bin 2 flow, so that the coffee beans enter the bean feeding bin 11 through the feeding hole at the bottom of the storage bin 2. At the same time, the feeding plate 8 will also divide the interior of the bean feeding bin 11 into various small areas. When the feeding plate 8 rotates, it will also push the coffee beans to move, so that the coffee beans enter the transmission tube 12 from the feeding hole at the bottom of the bean feeding bin 11, and then be transported to the grinding bin 4 for grinding.

[0040] When the drive mechanism is running, the drive motor 5 will drive the first bevel gear 6 to rotate, which in turn drives the second bevel gear 7 to rotate, which in turn drives the lower bean plate 8 to rotate. At the same time, the first bevel gear 6 will also drive the third bevel gear 13 to rotate, which in turn drives the grinding shaft 14 to rotate. This allows the grinding shaft 14 to grind the coffee beans in conjunction with the inner wall of the grinding chamber 4. Simultaneously, the grinding shaft 14 will also drive the crushing shaft 15 to rotate inside the filter chamber 16, so that the coffee bean powder is ground again by the crushing shaft 15 after entering the filter chamber 16, and then passes through the filter screen 17 to be transported to the heating chamber 18.

[0041] When coffee bean powder is stuck to the top of the filter screen 17, the grinding shaft 15 scrapes off the coffee bean powder stuck to the top because it is in contact with the filter screen 17.
