[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This coffee extract production device features an extraction mechanism equipped with two layers of filters.

[0017] 2. This coffee extract production device is equipped with a vibration mechanism. When adding coffee powder and other raw materials to the extraction tank, vertical vibration helps the raw materials fall quickly to prevent clumping; horizontal vibration ensures that the raw materials are evenly distributed in the extraction tank. During the extraction tank cleaning stage, the vibration mechanism can achieve multi-directional vibration, impacting the tank walls and corners in all directions, quickly removing attached coffee residues, assisting in cleaning, ensuring the extraction tank is clean, and providing good conditions for subsequent production.

[0018] 3. This type of coffee extract production device, by providing a shock-absorbing mechanism, can effectively cushion the impact and vibration generated by the flow of coffee liquid, avoid loosening of pipes and wear of valves caused by long-term vibration, and extend the service life of the equipment. It can also perform a secondary filtration on the extracted coffee liquid to intercept residual impurities, and the filter components are easy to replace, ensuring that excellent filtration effects are always maintained, helping to improve the quality of the coffee liquid.

[0019] 4. This coffee extract production device utilizes a vibration-exciting mechanism and a damping mechanism to operate in tandem.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0038] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0039] Example 1: See Figures 1-4 The present invention provides a technical solution: a coffee extract production device, including an extraction tank 1, a bracket 2 is clamped on the bottom of the extraction tank 1, a top cover 4 is threadedly connected to the top of the extraction tank 1, an extraction mechanism 3 is clamped inside the extraction tank 1, a vibration mechanism 6 is fixedly connected to the outer surface of the bracket 2, a damping mechanism 7 is threadedly connected to the inside of the extraction tank 1, and an opening and closing valve 5 is threadedly connected to the outer surface of the damping mechanism 7. The extraction mechanism 3 includes:

[0040] The first sleeve 302 and the extraction tank 1 are internally provided with an arcuate surface 301, which is engaged with the first sleeve 302. The inner wall of the first sleeve 302 is fixedly connected to the first tripod 303, and the interior of the first tripod 303 is rotatably connected to the threaded rod 304. The outer surface of the first tripod 303 is fixedly connected to the telescopic sleeve 305, and the outer surface of the threaded rod 304 is threadedly connected to the through-hole tripod 306. The outer surface of the through-hole tripod 306 is engaged with the filter 1 308. Two filter screens 1 308 are symmetrically arranged on both sides of the first tripod 303. The symmetrical arrangement of the filter screen 1 308 is used for double-layer filtration of the extraction raw materials. The telescopic sleeve 305 is used to protect the threaded rod 304.

[0041] The extraction mechanism 3 also includes a rotating block 307, which is engaged with the filter screen 308. The internal thread of the threaded rod 304 is connected to the threaded cover 309, and the inside of the threaded cover 309 is engaged with a hexagonal plate 310. The hexagonal plate 310 is flush with the threaded cover 309 and is used to protect the threaded cover 309.

[0042] The lower surface of the top cover 4 contacts the upper surface of the first sleeve 302, the outer surface of the first sleeve 302 contacts the inner wall of the extraction tank 1, the upper surface of the telescopic sleeve 305 is fixedly connected to the lower surface of the through-hole tripod 306, the upper surface of the through-hole tripod 306 contacts the lower surface of the filter 1 308, the rotating block 307 is threadedly connected to the through-hole tripod 306, the outer surface of the rotating block 307 contacts the inner wall of the first sleeve 302, and the rotating block 307 is used to limit the position of the filter 1 308. The first sleeve 302 is a plastic transparent product and has a scale on the surface, which can accurately locate and record the position adjustment of the filter 1 308. After the extraction mechanism 3 is cleaned, the position adjustment of the filter 1 308 can be assisted, and the changes in the position of the filter 1 308 caused by different coffee bean characteristics, roasting degree and target flavor can be recorded, which is convenient for targeted adjustment. When adding raw materials to the extraction tank 1, the raw materials will press the filter 1 308 When the filter 308 is impacted, the through-hole tripod 306 limits the filter 308, and the threaded rod 304 provides auxiliary support to ensure the stability of the position of the filter 308. At the same time, the telescopic sleeve 305 blocks the raw material and water source to prevent them from contacting the threaded rod 304, thereby protecting the threaded rod 304.

[0043] The working principle of this embodiment is as follows: when using this coffee extract production device, the through-hole tripod 306 is rotated on the surface of the threaded rod 304 and the through-hole tripod 306 is moved downward, the filter screen 1 308 is sleeved on the threaded rod 304, and is pushed downward to engage the through-hole tripod 306 with the filter screen 1 308, and the threaded cover 309 is threadedly fixed to the threaded rod 304 through the bolt hole, and the hexagonal plate 310 is engaged with the threaded cover 309. At this time, the rotating clamping block 307 is threadedly connected to the through-hole tripod 306 to limit the filter screen 1 308 on both sides in the vertical direction. Then, by rotating the through-hole tripod 306, the filter screen 1 308 is driven to move on the outer surface of the threaded rod 304, and the filter screen 1 308 is adjusted according to the scale on the surface of the first sleeve 302. The position is adjusted, and the double-layer filter 308 is adjusted through the symmetrically arranged extraction mechanism 3. The extraction mechanism 3 is then engaged with the extraction tank 1 so that the lower surface of the first sleeve 302 contacts the upper surface of the arcuate surface 301. At this time, the rotating top cover 4 is threadedly connected to the extraction tank 1 and is limited by the lower surface of the top cover 4 and the first sleeve 302. At this time, the raw materials and water source of the coffee extract are added through the through holes of the top cover 4, and the raw materials are extracted through the double-layer filter 308 and collected by opening and closing the valve 5. After the extraction is completed, when it is necessary to clean the extraction tank 1 and the extraction mechanism 3, the top cover 4 is rotated in the opposite direction and the extraction mechanism 3 is removed. The extraction tank 1 and the extraction mechanism 3 are cleaned, and the filter 308 is replaced by rotating the rotating block 307 to ensure the quality of the extraction.

[0044] Example 2: Please refer to Figure 5-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the vibration mechanism 6 includes a rotating rod 602, the interior of the extraction tank 1 is provided with a first card slot 601, the first card slot 601 is rotatably connected to the rotating rod 602, the outer surface of the rotating rod 602 is slidably connected with a pad 1 603, a cam 604 and a pad 2 605, the interior of the rotating rod 602 is connected with a motor 606, the outer surface of the motor 606 is fixedly connected with a bottom cover 609, the outer surface of the bottom cover 609 is threadedly connected with a second sleeve 607, the interior of the second sleeve 607 is provided with a ventilation groove 608, the outer surface of the bracket 2 is fixedly connected with a spring 610, and the ventilation groove 608 is used to dissipate heat for the motor 606.

[0045] The cam 604 is located between the pad 1 603 and the pad 2 605. The pad 1 603 and the pad 2 605 are made of rubber. The rotation radius of the cam 604 is smaller than the inner diameter of the second sleeve 607. The outer surface of the bottom cover 609 is flush with the outer surface of the second sleeve 607. The bottom cover 609 is used to limit the motor 606. The second sleeve 607 is plugged into the bracket 2. The second sleeve 607 is fixedly connected to the lower surface of the extraction tank 1. The spring 610 is fixedly connected to the lower surface of the extraction tank 1. The spring 610 is sleeved with the second sleeve 607. The spring 610 is used to elastically support the extraction tank 1. When the motor 606 fails, the bottom cover 609 can be rotated in the opposite direction to remove the motor 606 and the bottom cover 609 to achieve the motor 606. Maintenance and replacement, and the connection between the motor 606 and the rotating rod 602 ensures that the rotation of the rotating rod 602 is not affected. When the motor 606 drives the cam 604 to generate multi-directional vibrations, the three symmetrically arranged motors 606 work intermittently to ensure that they do not affect each other and the raw materials are evenly distributed. The work of the motor 606 is dissipated through the air permeable groove 608. The spacing between the double-layer filter 308 of the extraction mechanism 3 can be flexibly adjusted to effectively control the flow and distribution of the raw materials in the extraction tank 1, so that the raw materials are evenly spread in the extraction area to avoid local abnormalities. At the same time, the vibration mechanism 6 applies multi-directional vibrations to promote the rolling and mixing of the raw materials, break the concentration gradient, enhance the contact between the extractant and the raw materials, and comprehensively ensure uniform and stable extraction.

[0046] The shock-absorbing mechanism 7 includes a bellows 1 701, which is fixedly connected to the upper surface of the top cover 4. A stepped groove 702 is provided on the outer surface of the opening and closing valve 5. The internal thread of the extraction tank 1 is connected to a clamping ring 1 703. The outer surface of the clamping ring 1 703 is fixedly connected to a bellows 2 704. The interior of the clamping ring 1 703 is clamped to a filter screen 2 705. The internal thread of the clamping ring 1 703 is connected to a clamping ring 2 706. The outer surface of the clamping ring 1 703 is fixedly connected to an elastic sheet 707. The elastic sheet 707 is used to limit the shock-absorbing mechanism 7.

[0047] The lower surface of the snap ring 1 703 is threadedly connected to the outer surface of the opening and closing valve 5, the lower surface of the snap ring 2 706 is in contact with the upper surface of the filter screen 2 705, the snap ring 2 706 is at the top of the filter screen 2 705, the outer surface of the elastic sheet 707 is fixedly connected to the outer surface of the bracket 2, the bellows 1 701 and the bellows 2 704 are used to cushion the top cover 4 and the opening and closing valve 5. The threaded connection between the snap ring 1 703 and the extraction tank 1 can be released, and the opening and closing valve 5 can be threadedly connected to the extraction tank 1 through the stepped groove 702, so that the extraction tank 1 can be temporarily closed when the cushioning mechanism 7 is maintained to avoid external influences on the extraction tank 1. The snap ring 2 706 is set on the top of the filter screen 2 705 to prevent the vibration from being transmitted to the snap ring 2 706 during cushioning, causing it to detach and affect the opening and closing valve 5.

[0048] The working principle of this embodiment is as follows: when using this type of coffee extract production device, when adding raw materials, the motor 606 drives the rotating rod 602 to rotate, so that the cam 604 rotates on the outer surface of the rotating rod 602 and moves up and down along the axis of the rotating rod 602, thereby generating vertical and horizontal auxiliary vibrations. When the cam 604 moves upward and rotates, the extraction tank 1 can be protected by the pad 1 603, and when the cam 604 moves downward and rotates, the rotating rod 602 can be protected by the pad 2 605. At this time, the vertical vibration helps the raw materials to fall quickly to avoid agglomeration of the raw materials, and the horizontal vibration allows the raw materials to be evenly distributed in the extraction tank 1. The cooperation of the three groups of symmetrically arranged vibration mechanisms 6 ensures that the vibrations of each other do not affect each other, thereby improving the effect of the vibration mechanism 6 on the extraction tank 1, and When 06 fails, the bottom cover 609 and the motor 606 are removed by rotating the bottom cover 609 in the opposite direction, and are repaired and replaced. When the extraction tank 1 is cleaned, the inner wall of the extraction tank 1 and the upper surface of the curved surface 301 are impacted in all directions by the multi-directional vibration of the vibration mechanism 6, so as to assist in cleaning and ensure that the extraction tank 1 is clean. When the vibration mechanism 6 is vibrating in the opposite direction, the top cover 4 and the connected pipes are protected by the expansion and contraction of the bellows 1 701, and the opening and closing valve 5 and the connected pipes are protected by the expansion and contraction of the bellows 2 704, and the expansion and contraction of the clamping ring 1 703 is limited by the elastic sheet 707 to keep it within a reasonable range. The damping mechanism 7 is removed by rotating the clamping ring 1 703 in the opposite direction, and the filter screen 2 705 is replaced by flipping the clamping ring 2 706 to ensure the quality and efficiency of the secondary filtration of the extract.
