Description

Technical Field

[0001] The present application belongs to the field of electrical appliances, and in particular relates to a three-in-one brewing structure that realizes automatic powder filling and pressing. Background Art

[0002] In the related art, the automatic powder pressing and brewing structure uses a motor to drive the powder pressing head, so that the powder pressing head and the motor move up and down as a whole, thereby realizing the powder pressing function. In this structure, the powder lowering channel and the powder pressing channel are in the same direction, and the powder filling and powder pressing channels overlap. During the powder pressing process, the residual powder in the lower powder channel will fall onto the powder pressing head. Over time, this will cause the powder pressing head to have insufficient travel, resulting in the inability to perform normal functions and affecting the reliability of product use. In addition, the communication between the lower powder channel and the powder pressing channel can easily cause water vapor to escape into the lower powder channel during the extraction solution, causing the powder grinding mill to be blocked and the machine to be unable to work normally. In addition, the processing technology requirements are relatively high. If one part is damaged, the entire device cannot be used. It can be seen that the automatic powder pressing and brewing structure in the related art has major limitations and defects. Summary of the Invention

The powder pressing module is equipped with a powder pressing head, and an extraction liquid inlet is provided at the bottom of the powder pressing head.

[0008] Furthermore, the fixed bracket includes a main bracket and a secondary bracket.

[0009] Furthermore, the sliding mechanism is also provided with a contact switch, which is used to control the opening and closing of the powder feeding mechanism.

[0019] 2. The brewing structure of this application avoids the situation where the powder feeding channel and the powder pressing channel overlap, and avoids the situation where the steam runs into the powder feeding channel during the extraction solution, which is likely to cause powder clogging in the powder feeding channel due to the connection between the powder feeding channel and the powder pressing channel.

[0020] 3.

When necessary, the sliding baffle can cover the powder feeding port to avoid the coincidence of the two channels of powder pressing and powder feeding. Moreover, the brewing structure of the present application makes the movements of the sliding baffle, the funnel, and the powder feeding head at the output end relatively stable, with high reliability and stability.

[0022] 5. The brewing structure of the present application realizes the process of automatic powder feeding and powder pressing through the principle of the crank rocker. It converts the rotary motion into a linear motion. By reasonably and ingeniously designing the crank radius and the force arm length of the first rocker assembly and the second rocker assembly, the amplification of force and a longer stroke are achieved, and the specific movement trajectories of the sliding baffle and the powder feeding head are respectively defined. This is simpler, more economical, and more suitable for specific space requirements than using linear guide rails in the automatic powder pressing brewing structure in the related technology. Moreover, the powder feeding direction of the present application can be variable, different from the direction of powder pressing and extraction; the powder feeding channel and the powder pressing channel do not coincide. The start-stop functions of each driving module in the module are realized by placing mechanical or electronic switches on both sides of the first rocker assembly and the second rocker assembly.

[0046] Refer to Figure 2, the powder feeding mechanism includes a powder feeding module 5; in the embodiment of the present application, the powder feeding module 5 is set as a hollow cylinder with a powder feeding channel 52, and the structure of the powder feeding module 5 can be changed, so that the powder feeding and filling directions can be variable. A powder outlet 51 is provided at the bottom of the powder feeding channel 52, and a powder feeding hole 118 is provided at the position of the main bracket 11 corresponding to the powder outlet 51.

[0047] Referring to Figure 4 and Figure 5 , the powder pressing mechanism includes a second driving module 12, a second rocker assembly 13, a powder pressing module, and a housing 16; the second driving module 12 is used to drive the second rocker assembly 13 to move, and the second rocker assembly 13 is used to control the movement of the powder pressing module to press the powder cake. The powder pressing module is configured with a powder pressing head 14, and an extraction liquid inlet 141 is provided at the bottom of the powder pressing head 14.

[0048] The second driving module 12 is provided with a second driving shaft 121, and two first card slots 122 are provided on the second driving shaft 121.

[0049] The second rocker assembly 13 includes a first rotating arm 131 and a second rotating arm 132; two sickle-shaped gripping arms 133 are provided on the second rotating arm 132.

A second card slot 134 is provided at the other end of the first rotating arm 131, and the second card slot 134 is engaged with the two first card slots 122, and the first rotating arm 131 can move around the second driving shaft 121.

[0050] In the embodiment of the present application, the upper half of the housing 16 is set as a hollow cube, and the lower half is set as a hollow cylinder. The housing 16 is fixedly connected to the main bracket 11. Third round holes 163 are respectively provided on both sides of the upper half of the housing 16. The second driving shaft 121 respectively passes through the third round holes 163, and the first card slot 122 is engaged with the second card slot 134, and then is fixedly connected through the third round holes 163 on the other side. The first rotating arm 131 moves around the second driving shaft 121, driving the second rotating arm 132 to move up and down.

[0051] A second output shaft 135 is provided at the bottom of the second rotating arm 132; the powder pressing module is configured with a powder pressing head 14, and the diameter of the powder pressing head 14 is smaller than the diameter of the cylinder of the lower half of the housing 16.

[0052] On both sides of the lower half of the housing 16, there are tracks 162. The second output shaft 135 can move up and down along the tracks 162, driving the powder pressing head 14 to move up and down.

[0053] Above the track 162, there is a third contact switch 114. When the second output shaft 135 drives the powder pressing head 14 to move to the highest point, the second rocker assembly 13 triggers the contact of the third contact switch 114.

[0054] On the main bracket below the track 162, there is a fourth contact switch 115. When the second output shaft 135 drives the powder pressing head 14 to move to the lowest point, the second rocker assembly 13 triggers the contact of the fourth contact switch 115.

[0055] The working principle of the embodiment of the present application is as follows:

[0056] The first drive shaft 99 of the first drive module 1 drives the first output shaft 3, driving the first rocker assembly 2 to rotate, and then driving the sliding baffle 6 and the sliding block 7 to move, so that the funnel 10 placed on the sliding block 7 moves to the lower powder outlet 51 of the powder feeding module 5. At this time, the first rocker assembly 2 triggers the first contact switch 81, and the first drive module 1 stops working. The powder feeding module 5 can be started and the powder filling function can be realized. After the powder feeding is completed, under the action of the first drive module 1, the funnel 10 returns to the initial position. At this time, the first rocker assembly 2 triggers the second contact switch 82, and the first drive module 1 stops working. The rear end of the sliding baffle 6 covers the lower powder outlet 51 to prevent the powder feeding module 5 from dropping powder and the steam during extraction in the funnel 10 from entering the powder feeding channel 52 and causing powder blockage.

[0057] When the first rocker assembly 2 triggers the second contact switch 82 to turn off, the first drive module 1 stops working. The funnel 10 is located below the powder pressing head 14 installed on the main bracket 11. At this time, the second drive module 12 is started. The second drive shaft 121 on the second drive module 12 drives the second rocker assembly 13. The second output shaft 135 on the second rocker assembly 13 drives the powder pressing head 14 to move downward along the powder pressing channel 161 provided inside the housing 16, thereby pressing the powder in the funnel 10. When the second rocker assembly 13 triggers the fourth contact switch 115, the second drive module 12 stops working. The water source enters the funnel 10 through the powder pressing head 14 to realize the extraction of the beverage. After the extraction is completed, the second drive module 12 works, and the powder pressing head 14 moves upward along the powder pressing channel 161 under the action of the second rocker assembly 13. When the second rocker assembly 13 triggers the third contact switch 114, the second drive module 12 stops working. The whole process is fast, quiet, simple and efficient in structure.

[0058] The brewing structure of the present application realizes the process of automatic powder feeding and powder pressing through the principle of a crank rocker mechanism, converting rotational motion into linear motion. By reasonably and ingeniously designing the crank radius and the length of the force arm of the first rocker assembly 2 and the second rocker assembly 13, the amplification of force and a longer stroke are achieved, respectively defining specific movement trajectories of the sliding baffle 6 and the powder feeding head 14. It is simpler, more economical and more suitable for specific space requirements than the automatic powder pressing brewing structure using linear guide rails in the related art. Moreover, the powder feeding and filling direction of the present application can be variable, different from the direction of powder pressing and extraction; the powder feeding channel 52 and the powder pressing channel 161 do not coincide. The start and stop functions of the drive module in the module are realized by placing mechanical or electronic switches on both sides of the first rocker assembly 2 and the second rocker assembly 13.

[0059] In summary, the brewing structure of the present application avoids the situation where the powder feeding channel 52 and the powder pressing channel 161 coincide, preventing the residual powder in the powder feeding channel 52 from spilling onto the powder pressing head 14, avoiding the defect that the running stroke of the powder pressing head 14 will be insufficient after a long time, and solving the problem that the normal function of the powder pressing head cannot be carried out due to the coincidence of the powder feeding channel 52 and the powder pressing channel 161. The brewing structure of the present application also avoids the situation where the powder feeding channel 52 communicates with the powder pressing channel 161, which is likely to cause water vapor to run into the powder feeding channel 161 during the extraction solution, resulting in powder grinding blockage. The present application can close the powder feeding channel 52 during the process of moving the funnel 10, preventing the powder feeding channel 52 from being affected by moisture and powder dropping, and solving the problem that the machine cannot operate due to the powder grinding blockage in the powder feeding channel 52 caused by the communication between the powder feeding channel 52 and the powder pressing channel 161. The present application provides a three-in-one brewing structure for automatic powder filling and pressing, which drives the funnel 10 to move between the powder feeding position and the powder pressing position by the first rocker assembly 2, and the sliding baffle 6 can cover the powder feeding port 51, thus avoiding the coincidence of the two channels of powder pressing and powder feeding. Moreover, the movement of the sliding baffle 6, the funnel 10 and the powder feeding head 14 at the output end of the brewing structure of the present application is relatively stable, with high reliability and stability.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
