Description

Technical Field

[0001] The invention relates to the technical field of coffee machines, in particular to a mechanism for automatically, accurately and quantitatively delivering cleaning pills. Background Art

[0002] Coffee is one of the most popular drinks in the world, which brings joy and excitement to people. With my country's reform and opening up, the most popular Italian espresso, cappuccino and latte milk coffee in the world have also been placed on the Chinese table and are loved by more and more people. People have applied electronic technology to coffee machines, realizing the automatic control of the entire process of brewing coffee, such as grinding, pressing, filling, brewing, and removing residues, and created fully automatic coffee machines.

[0003] The coffee machine needs to be cleaned during use, and cleaning pills are used for cleaning during the cleaning process. However, the traditional cleaning pill dispensing mechanism will damage the pills during dispensing, resulting in an inconsistent amount of cleaning pills and incomplete cleaning.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example:

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

[0030] The rotating shaft 9 is rotatably arranged 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 fixing seat 6, and the motor PCB board 8 is also fixedly connected to the motor fixing seat 6, and the motor PCB board 8 is electrically connected to the motor 7. A blanking port is provided at the bottom of the cavity 1, and a groove 17 adapted to the blanking port is provided inside the rotating shaft 9, and a cam 16 is fixedly connected to the outer surface of the rotating shaft 9.

[0031] Four first connecting columns 10 are fixedly connected to the bottom of the cavity 1, four first fixing ears 12 are fixedly connected to the outer surface of the upper sleeve 2, and four second fixing ears 13 are fixedly connected to the outer surface of the lower sleeve 3. The first connecting column 10 is connected to the corresponding first fixing ear 12 and the second fixing ear 13 by bolts. The outer surface of the sensor fixing frame 4 is fixedly connected to two third fixing ears 14, and the third fixing ears 14 are clamped on the lower sleeve 3. The bottom of the cavity 1 is fixedly connected to two second connecting columns 11, and the outer surface of the motor fixing seat 6 is fixedly connected to two fourth fixing ears 15, and the fourth fixing ears 15 are connected to the corresponding second connecting columns 11 by bolts. The four internal surfaces of the cavity 1 are all set as inclined surfaces, so that the cleaning pills always keep the tendency to roll toward the blanking port of the cavity 1; there is a single channel in the middle of the cavity 1, and the channel width only allows a single cleaning pill to pass through; there is a height difference on both sides of the blanking port of the cavity 1, that is, Figure 6 The middle inclined surface a and the inclined surface b have a height difference, which reduces the probability of the cleaning pills being blocked at the blanking port of the cavity 1.

[0032] Working principle:

[0033] When the cleaning pills are not stuck in the feeding port of the cavity 1, the cleaning pills fall into the groove 17 of the rotating shaft 9 along the channel of the cavity 1 under the action of gravity (only one cleaning pill can enter 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 loaded with cleaning pills, the inner walls of the upper sleeve 2 and the lower sleeve 3 are supported to ensure that the cleaning pills always fall into 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 pills fall freely to the next channel, during this process, the infrared sensor 5 will detect, and when the set number of cleaning pills are detected, the motor PCB board 8 controls the motor 7 to stop rotating;

[0034] When the cleaning pills are stuck in the blanking port of cavity 1, the motor PCB board 8 controls the motor 7 to rotate, and the motor 7 drives the rotating shaft 9 to rotate. When the cam 16 of the rotating shaft 9 passes through the blanking port of cavity 1, the cam 16 on the rotating shaft 9 moves the cleaning pills stuck in the blanking port of cavity 1, so that the cleaning pills can smoothly enter the groove of the rotating shaft 9 (only one cleaning pill can enter at a time), and then the motor 7 continues to drive the rotating shaft 9 to rotate (during the rotation of the rotating shaft 9 loaded with cleaning pills, it is supported by the inner walls of the upper sleeve 2 and the lower sleeve 3 to ensure that the cleaning pills always fall into 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 pills fall 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.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprising a reference structure" do not exclude the existence of other identical elements in the process, method, article or device including the elements.
