Description

TECHNICAL FIELD

[0001] The utility model relates to the field of beverage preparation, and in particular to an automatic package dropping mechanism of a beverage preparation device and a beverage preparation device applying the automatic package dropping mechanism. BACKGROUND

[0002] In order to achieve the effect of automatic separation of the paper package after brewing, the beverage preparation device generally adopts an automatic package dropping mechanism. Taking coffee as an example, there are hundreds of paper package coffee brands on the market. Although the 45mm circular coffee cake inside them is consistent in size, the design of the paper package edge is unique and lacks a unified standard. The automatic package dropping mechanism adopts various strategies to fix the paper package, and most designs focus on the peripheral part of the paper package. This approach has obvious limitations.

[0003] For example, Chinese invention patent application 202210380486.0 (publication number CN 114931319 A) proposes an automatic package dropping device for powder capsule coffee machine. The collet fixes the paper package by clamping the skirt on both sides of the middle part of the paper package. Due to the difference in the edge size of different brands of paper packages, using this structure to fix the paper package, assuming that the diameters of different paper packages differ by 2mm, this will result in a height difference of 7.5mm, and the center of the paper package will be offset from the center of the brewing chamber, which may adversely affect the coffee brewing effect, so a machine cannot be used with coffee packages of different edge sizes. In reality, coffee packages produced by different manufacturers often have consistent sizes of the coffee cake part, which is 45mm in diameter, but the edge sizes are not the same, so a machine can often only be used to extract coffee packages produced by a certain manufacturer, and cannot be compatible with coffee packages produced by other manufacturers.

[0004] Another patent, application number 201310361909.5 (publication number CN 103417120 A), proposes a paper package coffee machine brewing device. The package support frame supports the paper package from the bottom. In this structure, assuming that the diameters of different paper packages differ by 2mm, the height difference is 1mm. Compared with the previous patent, this design is more adaptable to different specifications of paper packages, but there is still a difference, and the above problems still exist. Moreover, during the dropping process, the skirt of the paper package may deform due to gravity, resulting in unpredictable errors, which will make it difficult for the coffee brewing chamber to accurately accommodate the coffee cake part, thereby affecting the effective sealing of the brewing chamber and the extraction effect of the coffee.

[0005] Therefore, the existing brewing system has difficulty in adapting to various paper packages, and the main problem is that the different weights and external shapes of the paper packages make it difficult for the paper packages to stably vertically enter the brewing cavity and smoothly separate from the brewing cavity. In addition, the structure and operation mechanism of the beverage preparation equipment with the automatic paper dropping structure are relatively complex. Therefore, further innovation and improvement are still needed in view of the above-mentioned deficiencies. Utility model content

[0039] The utility model will be further described in detail below in combination with the embodiment of the drawings.

[0040] As Figures 1-12 shown, it is the preferred embodiment of the automatic package dropping mechanism and the beverage preparation equipment applying the automatic package dropping mechanism of the utility model.

[0041] The embodiment includes the base 1 with the handle 11, the paper package entrance 13 for putting in the paper package 2 is opened on the upper side of the base 1, the paper package entrance 13 is long and narrow along the left and right direction, and a sliding cover 12 is arranged on the paper package entrance 13, the sliding cover 12 is driven to slide back and forth by the handle 11. Figure 2 As shown, the sliding cover 12 moves backward to expose the paper package entrance 13 when the handle 11 is opened; as Figure 4 shown, the sliding cover 12 moves forward to cover the paper package entrance 13 when the handle 11 is closed.

[0042] The first machine part 5 is fixed, and the second machine part 3 is connected with the handle 11 and can move close to or away from the first machine part 5 in the machine base 1 of the beverage preparation device under the driving of the handle 11. When the handle 11 is completely closed, the second machine part 3 moves to the frontmost position of the movable position, and is folded with the first machine part 5, so that the brewing cavity is formed between the first machine part 5 and the second machine part 3.

[0043] The lower part of the second machine part 3 is connected with a paper packet holder 4, and the paper packet holder 4 is provided with a packet supporting groove 41 for supporting the paper packet 2. As shown in the drawings, the packet supporting groove 41 extends in the left-right direction, and the shape thereof is adapted to the arc of at least 1 / 5 of the bottom of the powder cake 21 of the paper packet 2. In this embodiment, the arc of about 1 / 4 of the bottom of the powder cake 21 of the paper packet is particularly selected as the positioning point, so as to ensure that accurate positioning and stable fixing can be realized regardless of the size or height of the paper packet skirt 22. Figure 9

[0044] The packet supporting groove 41 is in inverted trapezoidal or V-shaped cross section, and the bottom surface is provided with a position avoiding slot 42 for avoiding the paper packet skirt 22. The position avoiding slot 42 extends in the left-right direction and penetrates the bottom surface of the paper packet holder 4 downward. When the handle 11 is completely opened, the position of the packet supporting groove 41 corresponds to the position of the paper packet inlet 13 upward and downward. After the paper packet 2 is put into the machine base 1 from the paper packet inlet 13, the paper packet 2 falls into the packet supporting groove 41, the paper packet skirt 22 penetrates into the position avoiding slot 42, and the bottom of the powder cake 21 of the paper packet 2 is stably supported by the packet supporting groove 41 and moves into the brewing cavity along with the movement of the paper packet holder 4 in the subsequent process.

[0045] The paper packet holder 4 is rotationally connected with the second machine part 3, so that the paper packet holder 4 can change between the supporting state in which the opening of the packet supporting groove 41 faces upward and the disengaging state in which the paper packet holder 4 is flipped downward relative to the second machine part 3. Specifically, when the handle 11 is completely opened, the paper packet holder 4 is in the state in which the opening of the packet supporting groove 41 faces upward, and the paper packet holder 4 extends forward from the second machine part 3 in this state. In this state, the paper packet 2 is put into the machine base 1 from the paper packet inlet 13. Then, the handle 11 is closed. During the closing process, the paper packet holder 4 contacts the first machine part 5 earlier than the second machine part 3, and the paper packet holder 4 is rotated downward to change to the disengaging state after being subjected to the contact force. The second machine part 3 continues to move forward and contacts the first machine part 5 to close and form the brewing cavity. After the brewing is completed, during the opening process of the handle 11, the paper packet holder 4 moves backward to contact the machine base 1, and the paper packet holder 4 is rotated upward to return to the supporting state after being subjected to the contact force. Figure 2 Figure 3 Figure 4 Figures 6-8

[0046] ​​​​​In summary, when the handle 11 is fully closed, the paper package holder 4 rotates automatically downward due to the contact force, the paper package 2 is sent into the brewing chamber for brewing, after the brewing is completed, the handle 11 is opened to the maximum extent, the paper package 2 automatically falls, and the paper package holder 4 is reset to the supporting state after contacting the base 1, so as to support the next paper package 2.

[0047] Reference Figure 11 and Figure 12 In order to prevent the paper package holder 4 from rotating downward due to the gravity and causing the paper package 2 to be unable to be supported, the paper package holder 4 has a protruding clamping point 43, and the second machine element 3 is provided with a corresponding clamping opening 31, when the paper package holder 4 is in the supporting state, the clamping point 43 is clamped into the clamping opening 31, so as to fix the paper package holder 4.

[0048] Since when the paper package holder 4 starts to rotate downward, the second machine element 3 and the first machine element 5 have not been completely closed to form the brewing chamber, at this time, in order to ensure that the paper package 2 can still smoothly enter the brewing chamber after the supporting effect of the paper package holder 4 is removed, and also in order to prevent the paper package 2 from being unable to smoothly fall after the brewing is completed due to the mutual adhesion with the brewing chamber, the embodiment is provided with the paper package scraping plate 6. The paper package scraping plate 6 is connected to the rear side of the first machine element 5 through a spring, and under the action of the spring, the paper package scraping plate 6 always has a tendency to translate rearward, and the rear plate surface of the paper package scraping plate 6 is connected with at least one anti-adhesion spring 7, and the front side of the second machine element 3 is also provided with at least one anti-adhesion spring 7.

[0049] As Figure 3 shown, during the closing process of the handle 11, the paper package holder 4 contacts the first machine element 5 earlier than the second machine element 3, and starts to rotate downward under the contact force, at this time, the paper package 2 is clamped by the front and rear anti-adhesion springs 7, and no longer moves with the paper package holder 4. The paper package 2 is easy to be adhered to the brewing chamber after the brewing and cannot smoothly fall, and the paper package scraping plate 6 can drive the paper package 2 to retreat during the opening process of the handle 11, and the paper package 2 is separated from the front and rear anti-adhesion springs 7.

[0050] In order to further ensure the automatic falling of the paper package 2, the automatic falling mechanism of the embodiment further includes the paper package scraping plate 8. Referring to 2-8 and Figure 10 , the paper package scraping plate 8 is arranged between the first machine element 5 and the second machine element 3, and the paper package scraping plate 8 is elastically connected to the upper part of the base 1 through a spring, and the spring makes the paper package scraping plate 8 always have a tendency to move downward. During the closing process of the handle 11, the second machine element 3 is pushed to the first machine element 5, and the paper package scraping plate 8 is pushed upward and scrapes the hand grip 23 of the paper package skirt 22 to bend and press the hand grip 23. During the opening process of the handle 11, the spring releases the energy to drive the paper package scraping plate 8 to move downward, and pushes the paper package 2 to fall.

[0051] The embodiment also includes a micro switch 9, which is arranged on the front side of the base 1. The second machine part 3 is connected with a trigger for triggering the micro switch 9, as shown in Figure 10 When the handle 11 is fully closed, the trigger is moved forward with the second machine part 3 to contact the elastic sheet of the micro switch 9 to turn it on. This ensures that when the handle 11 is open, the micro switch 9 is off, and the machine cannot work by touching any button. When the handle 11 is fully closed, the micro switch 9 is automatically turned on, and the machine enters the ready state, and can work by touching the button.
