Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a mechanism for automatically, accurately, and quantitatively dispensing cleaning pills. Background Technology

[0002] Coffee is one of the world's most popular beverages, bringing people pleasure and excitement. With my country's reform and opening up, the world's most popular Italian espresso, cappuccino, and latte with milk have also appeared on Chinese tables and are increasingly loved by more and more people. People have applied electronic technology to coffee machines, realizing the automatic control of the entire coffee brewing process, including grinding, tamping, filling, brewing, and removing residue, thus creating fully automatic coffee machines.

[0003] Coffee machines need to be cleaned during use, and cleaning is done by adding cleaning pellets. However, traditional cleaning pellet dispensing mechanisms can damage the pellets during dispensing, resulting in inconsistent pellet amounts and incomplete cleaning. Damaged pellets also produce a lot of powder, causing contamination inside the coffee machine. Summary of the Invention

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] like Figure 1-7 As shown, this utility model embodiment provides a mechanism for automatically, accurately, and quantitatively dispensing cleaning pills, including a cavity 1, an upper sleeve 2 connected to the bottom of the cavity 1, a lower sleeve 3 connected to the bottom of the upper sleeve 2, a sensor mounting bracket 4 connected to the lower sleeve 3, an infrared sensor 5 fixedly connected to the sensor mounting bracket 4, a motor mounting base 6 connected to one side of the bottom of the cavity 1, a motor 7 fixedly connected to the motor mounting base 6, and a rotating shaft 9 fixedly connected to the output shaft of the motor 7.

[0030] The rotating shaft 9 is rotatably disposed inside the upper sleeve 2 and the lower sleeve 3, and the upper sleeve 2 and the lower sleeve 3 are connected to the motor mounting base 6. The motor mounting base 6 is also fixedly connected to the motor PCB board 8, which is electrically connected to the motor 7. The bottom of the cavity 1 is provided with a material discharge port, and the inside of the rotating shaft 9 is provided with a groove 17 that matches the material discharge port. The outer surface of the rotating shaft 9 is fixedly connected to a cam 16.

[0031] Four first connecting posts 10 are fixedly connected to the bottom of cavity 1. Four first fixing lugs 12 are fixedly connected to the outer surface of upper sleeve 2. Four second fixing lugs 13 are fixedly connected to the outer surface of lower sleeve 3. The first connecting posts 10 are connected to the corresponding first fixing lugs 12 and second fixing lugs 13 by bolts. Two third fixing lugs 14 are fixedly connected to the outer surface of sensor mounting bracket 4. The third fixing lugs 14 are snapped onto lower sleeve 3. Two second connecting posts 11 are fixedly connected to the bottom of cavity 1. Two fourth fixing lugs 15 are fixedly connected to the outer surface of motor mounting base 6. The fourth fixing lugs 15 are connected to the corresponding second connecting posts 11 by bolts. All four sides of the interior of cavity 1 are set as slopes, so that the cleaning pills always maintain the tendency to roll towards the discharge port of cavity 1. The middle of cavity 1 is a single channel, and the channel width only allows a single cleaning pill to pass through. There is a height difference on both sides of the discharge port of cavity 1. Figure 6 The inclined plane a and the inclined plane b have a height difference, which reduces the probability of the cleaning pill getting blocked at the discharge port of cavity 1.

[0032] Working principle:

[0033] When the cleaning pill is not stuck in the discharge port of cavity 1, the cleaning pill falls into the groove 17 of the rotating shaft 9 under the action of gravity (only one cleaning pill can be put in at a time). The motor PCB board 8 controls the motor 7 to rotate, and the motor 7 drives the rotating shaft 9 to rotate (during the rotation of the rotating shaft 9 with the cleaning pill, it is supported by the inner walls of the upper sleeve 2 and the lower sleeve 3 to ensure that the cleaning pill always falls in the groove 17 of the rotating shaft 9 before the rotation reaches 180 degrees). When the rotating shaft 9 rotates to 180 degrees, the cleaning pill falls freely to the next channel. During this process, the infrared sensor 5 will detect the cleaning pill. When the set number of cleaning pills is detected, the motor PCB board 8 controls the motor 7 to stop rotating.

[0034] When a cleaning pill gets stuck in the discharge port of cavity 1, the motor PCB board 8 controls the motor 7 to rotate. The motor 7 drives the rotating shaft 9 to rotate. When the cam 16 of the rotating shaft 9 passes the discharge port of cavity 1, the cam 16 on the rotating shaft 9 pushes the cleaning pill stuck in the discharge port of cavity 1, so that the cleaning pill can smoothly enter the groove of the rotating shaft 9 (only one cleaning pill can enter at a time). Then the motor 7 continues to drive the rotating shaft 9 to rotate (during the rotation of the rotating shaft 9 with the cleaning pill, it is supported by the inner walls of the upper sleeve 2 and the lower sleeve 3 to ensure that the cleaning pill always falls in the groove 17 of the rotating shaft 9 before the rotation reaches 180 degrees). When the rotating shaft 9 rotates to 180 degrees, the cleaning pill falls freely to the next channel. During this process, the infrared sensor 5 will detect. When the set number of cleaning pills is detected, the motor PCB board 8 controls the motor 7 to stop rotating.
