Description
TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of coffee powder pressing mechanism and coffee equipment. BACKGROUND
[0002] At present, with the continuous improvement of life quality and the continuous rise of coffee culture, people's requirements for brewing coffee are also getting higher and higher. However, when brewing coffee, the coffee powder needs to be pressed first. During the pressing process of coffee powder, the coffee powder press plays a crucial role in the processing of coffee powder. It ensures that hot water can penetrate uniformly by pressing and compacting the coffee powder, improving the extraction efficiency. The press can also increase the resistance of extraction, allowing coffee substances to be fully released, improving the taste and aroma of coffee. Using the press can maintain the stability of the coffee powder structure, prevent imbalance during extraction, and make the coffee more full-bodied and mellow. Therefore, for people who pursue high-quality coffee, the coffee press is an indispensable tool that makes every cup of coffee full of layers and delicacy, enjoying the wonderful experience of coffee. In the prior art, most of the presses are manually or automatically pressed on the coffee powder. When the press is pressed on the coffee powder, the pressing block is raised and lowered to compact the coffee cake, thereby achieving the effect of pressing. However, when the press is pressed on the coffee powder, the pressing block will move up and down. During the downward movement, the motion gravity generated by manually rotating the downward pressing block or the power provided by the automatic press will cause the pressing block to sway left and right during the downward movement, which cannot compact the coffee powder along the vertical trajectory. Due to the sway of the pressing block during the downward movement, the coffee powder is unevenly stressed, causing some parts of the coffee cake to be pressed too tightly, while other parts are relatively loose, affecting the penetration speed and extraction speed of hot water when brewing coffee powder, and thus affecting the taste and flavor of coffee.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0029] like Figures 1 to 3 As shown, a coffee tamping mechanism 10 of one embodiment is used to tamp coffee powder in the inner cavity of the coffee bowl assembly 800; the coffee tamping mechanism 10 includes a tamping block 200, a rotary drive 300 and a rotary shaft 400, wherein the rotary drive 300 is used to be mounted on the housing 100.
[0030] In the embodiment, the driving end of the rotating driving member 300 is connected to the first end of the rotating shaft 400, the second end of the rotating shaft 400 is threadedly connected to the powder pressing block 200, the powder pressing block 200 is used for sliding connection to the shell 100, and the rotating driving member 300 is used for driving the rotating shaft 400 to rotate, so as to drive the powder pressing block 200 to slide relative to the shell 100, so that the powder pressing block 200 moves up and down relative to the powder bowl assembly 800.
[0031] It can be understood that, by connecting the driving end of the rotating driving member 300 to the first end of the rotating shaft 400, and threadedly connecting the second end of the rotating shaft 400 to the powder pressing block 200, when the rotating shaft 400 rotates, the powder pressing block 200 is driven to move up and down, and the powder pressing block 200 is slidingly connected in the interior of the shell 100, so that when the rotating driving member 300 drives the rotating shaft 400 to move up and down, the powder pressing block 200 slides on the inner circumferential wall of the shell 100. Since the powder pressing block 200 always moves up and down on the inner circumferential wall of the shell 100, the powder pressing block 200 is prevented from shaking left and right during the up and down movement due to the movement of the rotating driving member 300 during the pressing process, the stability and accuracy during the pressing process are ensured, and the powder pressing block 200 is accurately stressed on the coffee powder, so as to ensure the penetration speed and extraction speed of hot water when the coffee powder is brewed.
[0032] It should be noted that the rotating driving member 300 is any one of a transmission motor, a stepping motor and a driving cylinder.
[0033] As shown in Figure 1 In one embodiment, the powder pressing block 200 includes a powder pressing block body 210 and a guide sliding block 220, the guide sliding block 220 is slidingly arranged in the shell 100, and the guide sliding block 220 is connected to the powder pressing block body 210. It can be understood that the powder pressing block 200 is divided into the powder pressing block body 210 and the guide sliding block 220, and the guide sliding block 220 is connected to the powder pressing block body 210 and slidingly arranged in the shell 100. When the rotating driving member 300 drives the powder pressing block 200 to move up and down through the rotating shaft 400, since the guide sliding block 220 is slidingly arranged in the shell 100, the powder pressing block 200 can only move up and down along the track of the inner circumferential wall of the shell 100, so that the powder pressing block 200 always maintains a stable movement track during the pressing process, and the coffee powder of the powder bowl assembly 800 is compacted.
[0034] In combination with Figure 2 and Figure 3As shown, in one embodiment, the coffee powder pressing mechanism 10 further comprises a micro switch 500 arranged in the shell 100, the micro switch 500 comprises a switch body 510, a pressing shaft 520 and an elastic reset member 530, the switch body 510 is provided with a switch paddle 5110, one end of the pressing shaft 520 is connected to the bottom of the shell 100, the other end of the pressing shaft 520 abuts against the end face of the switch paddle 5110, and the elastic reset member 530 is sleeved on the pressing shaft 520. It can be understood that the micro switch 500 is arranged in the interior of the shell 100, the switch body 510 is provided with the switch paddle 5110, one end of the pressing shaft 520 is connected to the bottom of the shell 100, and the other end of the pressing shaft 520 abuts against the end face of the switch paddle 5110. When the powder bowl assembly 800 is sleeved on the bottom of the shell 100 and is screwed to the shell 100, the pressing shaft 520 is driven to make the switch paddle 5110 slightly move upward, thereby triggering the switch body 510, so that the rotary driving member 300 is started to drive the powder pressing block 200 to compact the coffee powder. At the same time, the elastic reset member 530 is sleeved on the pressing shaft 520. When the powder pressing block 200 completes the powder pressing, the powder pressing assembly is removed, so that the elastic reset member 530 can reset the pressing shaft 520, the switch paddle 5110 is reset downward, thereby stopping the rotary driving member 300 from working, and the effect that the rotary driving member 300 works automatically when the powder bowl assembly 800 is screwed and the powder pressing block 200 reaches the effect of compacting the coffee powder is achieved.
[0035] As shown, Figure 1 In one embodiment, the first end of the rotating shaft 400 is fixedly connected to the driving end of the rotary driving member 300, and the second end of the rotating shaft 400 is threadedly connected to the powder pressing block 200. It can be understood that the first end of the rotating shaft 400 is fixedly connected to the driving end of the rotary driving member 300, and the second end of the rotating shaft 400 is threadedly connected to the powder pressing block 200. When the rotary driving member 300 drives the rotating shaft 400 to reverse, the powder pressing block 200 moves up and down relative to the rotating shaft 400, so that the powder pressing block 200 moves close to or away from the powder bowl assembly 800 when the rotary driving member 300 works.
[0036] In combination with Figure 1 and Figure 3As shown, in one embodiment, the coffee powder pressing mechanism 10 further comprises a controller 600, which is arranged in the housing 100, and the controller 600 is electrically connected to the micro switch 500 and the rotary drive 300 respectively. The controller 600 receives the signal of the micro switch 500, so that the controller 600 drives the power output shaft of the rotary drive 300 to rotate. It can be understood that when the powder bowl assembly 800 is screwed and triggers the micro switch 500, the micro switch 500 will immediately send a signal to the controller 600. After receiving the signal, the controller 600 will quickly analyze the operation to be performed at present, and the controller 600 is electrically connected to the rotary drive 300, so that the controller 600 controls the power output of the rotary drive 300 to start rotating. During this process, the controller 600 not only ensures the accuracy of signal transmission, but also realizes the function of automatically compacting coffee powder of the coffee powder pressing mechanism 10.
[0037] The application also includes a coffee device, which comprises a housing 100, a powder bowl assembly 800 and the coffee powder pressing mechanism 10 of any of the above embodiments. It can be understood that the pressing block 200 is slidably connected in the inside of the housing 100, so that when the rotary drive 300 drives the rotary shaft 400 to move up and down, the pressing block 200 will slide on the inner circumferential wall of the housing 100. Since the pressing block 200 always moves up and down on the inner circumferential wall of the housing 100, the situation that the pressing block 200 shakes left and right during the up and down movement caused by the movement of the rotary drive 300 during the pressing process is avoided, which ensures the stability and accuracy of the pressing process.
[0038] In combination Figure 1 With Figure 2 As shown, in another embodiment, the pressing block 200 is provided with a guide sliding groove 2210, and the housing 100 is provided with a limiting assembly 700, and the guide sliding groove 2210 is slidably connected to the limiting assembly 700, so that the pressing block 200 moves up and down relative to the powder bowl assembly 800. It can be understood that the guide sliding groove 2210 is slidably connected to the limiting assembly 700 by providing the guide sliding groove 2210 in the pressing block 200 and the limiting assembly 700 in the housing 100, and the limiting assembly 700 makes the pressing block 200 always move up and down in the housing 100, which limits the left and right shaking of the pressing block 200 during the up and down movement, thereby avoiding the uneven stress during the compaction of coffee powder.
[0039] In combination Figure 1 With Figure 2As shown, further, the limiting assembly 700 further comprises a limiting sleeve 710 and a guide column 720, the limiting sleeve 710 is provided with a sliding cavity 7110, the limiting sleeve 710 is provided with a mounting hole 7120, the guide column 720 is screwed in the mounting hole 7120 and penetrates the sliding cavity 7110, and the guide sliding groove 2210 is slidingly connected to the guide column 720. It can be understood that the limiting sleeve 710 is provided with the mounting hole 7120, the guide column 720 is screwed in the mounting hole 7120 and penetrates the sliding cavity 7110, and the guide sliding groove 2210 is slidingly connected to the guide column 720, so that the powder compacting block 200 can move up and down along the trajectory of the guide column 720, ensuring that the powder compacting block 200 can stably move up and down along the trajectory of the guide column 720.
[0040] As shown in the drawings, Figure 2 In another embodiment, the number of guide sliding grooves 2210 is two, the two guide sliding grooves 2210 are arranged at intervals along the periphery of the powder compacting block 200, and the number of guide columns 720 is two, each guide column 720 is slidingly arranged in the corresponding guide sliding groove 2210. It can be understood that two guide sliding grooves 2210 and two guide sliding grooves 2210 are arranged at intervals along the periphery of the powder compacting block 200, and one guide column 720 is slidingly arranged in the corresponding guide sliding groove 2210, which is conducive to preventing the powder compacting block 200 from tilting or deviating during the lifting process, ensuring that the powder compacting block can maintain a vertical and stable movement trajectory, and improving the accuracy of the entire powder compacting process.
[0041] In combination with Figure 1 As shown in the drawings, Figure 4 In one embodiment, the shell 100 comprises a shell body 110 and a clamping ring 120, the clamping ring 120 is arranged at the bottom of the shell body 110, the inner peripheral wall of the clamping ring 120 is provided with a connecting boss 1210, and the clamping block 810 of the powder bowl assembly 800 is clamped to the connecting boss 1210. It can be understood that the inner peripheral wall of the clamping ring 120 protrudes the connecting boss 1210, so that the clamping block 810 of the powder bowl assembly 800 can be clamped on the connecting boss 1210, thereby realizing the close connection between the shell 100 and the powder bowl assembly 800, ensuring the stability between them, avoiding falling off or shaking, improving the use safety and the overall stability of the product.
[0042] Compared with the prior art, the present disclosure has at least the following advantages:
[0043] The driving end of the rotating driving part 300 is connected to the rotating first end, and the second end of the rotating shaft 400 is threadedly connected to the powder compact 200. When the rotating shaft 400 rotates, the powder compact 200 is driven to move up and down. The powder compact 200 is slidably connected in the inside of the shell 100. When the rotating driving part 300 drives the rotating shaft 400 to move up and down, the powder compact 200 slides on the inner circumferential wall of the shell 100. Since the powder compact 200 always moves up and down on the inner circumferential wall of the shell 100, the powder compact 200 does not shake left and right during the pressing process due to the movement of the rotating driving part 300, ensuring the stability and accuracy of the pressing process, and ensuring that the powder compact 200 is accurately stressed on the coffee powder, thereby ensuring the penetration speed and extraction speed of hot water when brewing coffee powder.
