Description

Technical Field

[0001] The utility model relates to the field of coffee machines, in particular to a coffee bean shortage detection auxiliary device applied to coffee machines. Background Art

[0002] There are three types of coffee machines on the market: capsule machines, semi-automatic machines and fully automatic machines. For fully automatic coffee machines, users only need to press the coffee button to automate the entire process from grinding coffee beans to brewing coffee with hot water. Coffee machines are usually equipped with a bean bin for storing coffee beans. The coffee beans in the bean bin can satisfy the continuous coffee making of the coffee machine. During the use of the coffee machine, the coffee beans will gradually be consumed. When there are not enough coffee beans in the bean bin, the user may ignore the coffee bean shortage signal and continue to prepare coffee when the coffee beans are insufficient until the coffee bean plate and the grinder are empty. Therefore, the coffee brewed in the end is not a complete dose of coffee, and the taste of the coffee will not match the expected result of the user. Summary of the invention

[0003] The technical problem to be solved by the utility model is that when there are insufficient coffee beans in the bean bin, the user may ignore the coffee bean shortage signal and continue to prepare coffee when the coffee beans are insufficient, and the user may not find out until the coffee bean tray and the grinder are empty. Therefore, the coffee finally brewed is not a complete dose of coffee, and the taste of the coffee will not match the result expected by the user.

[0004] To solve the above problems, the technical solution adopted by the utility model is: a coffee bean shortage detection auxiliary device applied to a coffee machine, comprising a coffee machine body and a bean bin arranged at the upper end of the coffee machine body, the bean bin comprising a bean storage box and a box cover arranged at the upper end of the bean storage box, a fixed partition is fixedly provided inside the bean storage box, a drop-out port is opened on one side of the fixed partition, a sealing plate is hingedly provided at the lower end of the fixed partition through a reset hinge, and an auxiliary component matching the sealing plate is provided at the upper end of the box cover.

[0005] The beneficial effects of the utility model are as follows: through the hinged cooperation between the sealing plate and the fixed partition, the sealing plate can be turned over to different degrees according to the gravity of the coffee beans in the bean storage box, and by providing an auxiliary component that cooperates with the sealing plate, it is convenient for the staff to judge the turning degree of the sealing plate, and then judge the remaining amount of coffee beans in the bean storage box.

[0006] As a further improvement of the present invention, the technical problem to be solved is: it is difficult for the staff to intuitively judge the remaining amount of coffee beans in the bean bin.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the auxiliary component includes a sliding rod sliding through the box cover and a transparent cover fixed to the upper end of the box cover, the upper end of the sliding rod movably penetrates into the transparent cover and is provided with a blocking block.

[0008] The beneficial effect of the above improvement is as follows: by providing a transparent cover, a blocking block and a sliding rod, when there is insufficient coffee beans in the bean storage box, the sealing plate flips upward under the resetting action of the resetting hinge, thereby lifting the sliding rod, driving the sliding rod and the blocking block to move upward, and the staff can judge the remaining amount of coffee beans in the bean storage box by observing the height of the blocking block.

[0009] As a further improvement of the utility model, the technical problem to be solved is: when the remaining amount of coffee beans is insufficient, it is difficult to remind the staff in time.

[0010] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: an infrared emitting end is fixedly provided on the outer side of the transparent cover, a receiving end corresponding to the infrared emitting end is provided on the other side of the transparent cover, and an audible and visual alarm and a PLC controller are respectively provided on the upper end of the box cover, the receiving end is electrically connected to the PLC controller, and the audible and visual alarm is electrically connected to the PLC controller.

[0011] The beneficial effects of the above improvement are as follows: by setting up an audible and visual alarm, an infrared transmitting end, a receiving end and a PLC controller, when there is insufficient coffee beans in the bean storage box, the sealing plate flips upward under the resetting action of the resetting hinge, thereby squeezing the sliding rod to move upward, driving the blocking block to move upward, and the infrared rays emitted by the infrared transmitting end are blocked by the blocking block, so that the receiving end cannot receive the signal and feed it back to the PLC controller. The PLC controller drives the audible and visual alarm to send out an audible and visual alarm to promptly remind the staff.

[0012] The utility model further improves the technical solution adopted as follows: a conical block matched with the sealing plate is provided at the lower end of the slide rod, and the lower end of the conical block is spherical.

[0013] The beneficial effects of the above improvement are as follows: by providing the conical block, on the one hand, the friction between the conical block and the sealing plate is effectively reduced; on the other hand, it is convenient for the slide rod and the conical block to be inserted downward into the bean storage box storing coffee beans.

[0014] The utility model further improves the technical solution adopted as follows: a rounded corner is arranged at the upper opening of the blanking opening.

[0015] The beneficial effect of the above improvement is: effectively preventing coffee beans from accumulating near the upper opening of the drop port. BRIEF DESCRIPTION OF THE DRAWINGS
