Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a feeder for self-service coffee machines. Background Technology

[0002] Self-service coffee machines are mainly used to automatically make various coffee drinks. They are highly automated, and users only need to operate them to make coffee. The entire process, from grinding coffee beans to brewing coffee, can be automated.

[0003] Existing self-service coffee machines use a motor to drive a half-gear to rotate when adding coffee powder to the filter basket. This half-gear, in conjunction with a rack, moves a slide to open the feed hopper. When the half-gear disengages from the rack, the slide, under the action of a spring, returns to its original position and closes the feed hopper, completing one feeding cycle. However, this method only adds the same amount of coffee powder each time, while different flavors of coffee require different amounts of powder, resulting in variations in taste when brewing different flavors of coffee. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a feeder for a self-service coffee machine to solve the technical problem that the existing self-service coffee machine feeds the same amount of coffee powder each time, while the amount of coffee powder required to brew different flavors of coffee is different, resulting in different tastes when brewing different flavors of coffee.

[0005] This utility model is achieved through the following technical solution:

[0006] A feeder for a self-service coffee machine includes a coffee machine body and a feed hopper installed on the top of the coffee machine body. A through groove is provided on the lower side of the feed hopper, and a dispensing plate is horizontally inserted in the through groove. The dispensing plate divides the internal space of the feed hopper into a storage space and a dispensing space. A first drive mechanism is installed on the feed hopper to drive the dispensing plate to move horizontally and connect the storage space and the dispensing space.

[0007] A sealing plate is hinged to the bottom opening of the discharge space, and a weighing component is installed on the sealing plate. A second drive mechanism is also installed on the hopper to drive the sealing plate to rotate and open the discharge space.

[0008] Furthermore, a groove is provided on the inner wall of the discharge space, and a through hole is provided on the side of the hopper to communicate with the groove, through which a push rod is inserted;

[0009] The end of the push rod extending into the groove is provided with a scraper, the end of the push rod extending out of the bin is fixedly provided with a connecting plate, a power source for driving the connecting plate to move along the length direction of the push rod is installed on the bin, and the power source is located on the same side of the connecting end of the sealing plate and the bin.

[0010] Further, a mounting groove is formed in the top surface of the sealing plate, the weighing assembly comprises a weighing sensor mounted in the mounting groove, and a weighing plate for covering the mounting groove.

[0011] Further, the scraper comprises a first plate body, the first plate body is matched with the groove in shape, a second plate body is mounted in the insertion groove formed in the bottom of the first plate body, and a spring is mounted between the second plate body and the top wall of the insertion groove.

[0012] Further, a first inclined surface is formed in the side of the second plate body facing the groove, a second inclined surface is formed in the groove wall of the groove, and the slopes of the first inclined surface and the second inclined surface are the same.

[0013] Further, two baffle plates are oppositely arranged on the top surface of the sealing plate along the length direction of the sealing plate, one end of the baffle plate is close to the scraper, the other end of the baffle plate extends out of the bin, an avoiding groove is formed in the bin, and the upper end of the baffle plate extends into the avoiding groove.

[0014] Further, a guide plate is obliquely arranged on the inner wall of the bin, and the guide plate is located below the end of the distribution plate extending into the interior of the bin.

[0015] Further, the ends of the two baffle plates extending out of the bin are jointly connected with a guide head, and the guide head is located at the end of the sealing plate.

[0016] Further, the power source adopts a multi-stage electric telescopic rod.

[0017] The beneficial effects of the utility model lie in:

[0018] When the feeder for the self-service coffee machine is used, after the user issues the instruction of making coffee through the operation panel, the controller first controls the first driving mechanism to drive the distribution plate to move out of the bin, so as to connect the storage space and the discharging space, at this time, the ground coffee powder in the storage space falls into the discharging space and is accumulated on the weighing assembly to be weighed, when the coffee powder approaches the target weight, the first driving mechanism drives the distribution plate to move back to reset, so as to reduce the connection amount of the storage space and the discharging space, and slow down the coffee powder feeding speed, thereby reducing the weight error of the coffee powder weighing;

[0019] When the coffee powder reaches the target weight required for brewing coffee, the first driving mechanism drives the distribution plate to completely block the storage space and the discharge space, and at this time the controller controls the second driving mechanism to start, which pushes the sealing plate to swing downward, thereby opening the bottom opening of the discharge space to pour the weighed coffee powder into the filter basket for brewing coffee, thereby realizing the corresponding quantitative addition of the required coffee powder when brewing different coffee, and ensuring the taste of the brewed coffee.
