For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Embodiment 1: Refer to 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 at 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 shock excitation mechanism 6 is fixedly connected to the outer surface of the bracket 2, a shock absorption mechanism 7 is threadedly connected inside the extraction tank 1, and an opening and closing valve 5 is threadedly connected to the outer surface of the shock absorption mechanism 7. The extraction mechanism 3 includes: A first sleeve 302, an arc surface 301 is provided inside the extraction tank 1, the arc surface 301 is clamped with the first sleeve 302, a first triangular frame 303 is fixedly connected to the inner wall of the first sleeve 302, a threaded rod 304 is rotatably connected inside the first triangular frame 303, a telescopic sleeve 305 is fixedly connected to the outer surface of the first triangular frame 303, a through-hole triangular frame 306 is threadedly connected to the outer surface of the threaded rod 304, a first filter screen 308 is clamped on the outer surface of the through-hole triangular frame 306, and two first filter screens 308 are symmetrically arranged on both sides of the first triangular frame 303. The symmetrical arrangement of the first filter screens 308 is used for double-layer filtering of the extraction raw materials, and the telescopic sleeve 305 is used for protecting the threaded rod 304.

[0024] The extraction mechanism 3 further includes a rotating block 307, the rotating block 307 is clamped with the first filter screen 308, a threaded cover 309 is threadedly connected inside the threaded rod 304, a hexagonal plate 310 is clamped inside the threaded cover 309, and the hexagonal plate 310 is flush with the threaded cover 309. The hexagonal plate 310 is used for protecting the threaded cover 309.

[0025] The lower surface of the top cover 4 is in contact with the upper surface of the first sleeve 302. The outer surface of the first sleeve 302 is in contact with 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 is in contact with the lower surface of the first filter screen 308. The rotating block 307 is threadedly connected to the through-hole tripod 306. The outer surface of the rotating block 307 is in contact with the inner wall of the first sleeve 302. The rotating block 307 is used to limit the position of the first filter screen 308. The first sleeve 302 is a plastic transparent product and has scales on its surface, which can accurately position and record the position adjustment of the first filter screen 308. After the extraction mechanism 3 can be cleaned, it can assist in the position adjustment of the first filter screen 308 and record the changes in the position of the first filter screen 308 caused by different coffee bean characteristics, roasting degrees, and target flavors, facilitating targeted adjustment. When adding raw materials to the extraction tank 1, the raw materials will impact the first filter screen 308. At this time, the through-hole tripod 306 plays a role in limiting the first filter screen 308, and the threaded rod 304 provides auxiliary support to ensure the stable position of the first filter screen 308. At the same time, the telescopic sleeve 305 blocks the raw materials and the water source to prevent them from contacting the threaded rod 304 and realizes the protection of the threaded rod 304.

[0026] The working principle of this embodiment is as follows: When using this coffee extract production device, rotate the through-hole tripod 306 on the surface of the threaded rod 304 and move the through-hole tripod 306 downward. Sleeve the first filter screen 308 onto the threaded rod 304 and push it downward to make the through-hole tripod 306 engage with the first filter screen 308. Then, through the bolt hole of the threaded cover 309, thread the threaded cover 309 onto the threaded rod 304 and make the hexagonal plate 310 engage with the threaded cover 309. At this time, the rotating block 307 is threadedly connected to the through-hole tripod 306 to limit the two sides of the first filter screen 308 in the vertical direction. Then, by rotating the through-hole tripod 306, drive the first filter screen 308 to move on the outer surface of the threaded rod 304. Adjust the position of the first filter screen 308 according to the scales on the surface of the first sleeve 302, and realize the adjustment of the double-layer first filter screen 308 through the symmetrically arranged extraction mechanism 3. Connect the extraction mechanism 3 to the extraction tank 1 so that the lower surface of the first sleeve 302 is in contact with the upper surface of the arc surface 301. At this time, rotate the top cover 4 to be threadedly connected to the extraction tank 1, and limit it through the lower surface of the top cover 4 and the first sleeve 302. At this time, add the raw materials and water source of the coffee extract through the through-hole of the top cover 4, extract the raw materials through the double-layer first filter screen 308, and collect them through the opening and closing valve 5. After the extraction is completed, when the extraction tank 1 and the extraction mechanism 3 need to be cleaned, reverse-rotate the top cover 4 and remove the extraction mechanism 3, clean the extraction tank 1 and the extraction mechanism 3, and replace the first filter screen 308 by rotating the rotating block 307 to ensure the quality of the extraction.

[0027] Embodiment 2: Please refer to Figures 5-8 , on the basis of Embodiment 1, the present invention provides a technical solution: The shock excitation mechanism 6 includes a rotating rod 602. A first card slot 601 is provided inside the extraction tank 1, and the first card slot 601 is rotatably connected to the rotating rod 602. A first cushion block 603, a cam 604, and a second cushion block 605 are slidably connected to the outer surface of the rotating rod 602. A motor 606 is clamped inside the rotating rod 602. A bottom cover 609 is fixedly connected to the outer surface of the motor 606. A second sleeve 607 is threadedly connected to the outer surface of the bottom cover 609. A ventilation slot 608 is provided inside the second sleeve 607. A spring 610 is fixedly connected to the outer surface of the support 2. The ventilation slot 608 is used to dissipate heat from the motor 606.

[0028] The cam 604 is located between the first cushion block 603 and the second cushion block 605. The first cushion block 603 and the second cushion block 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 inserted into the support 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 on 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 is rotated in the reverse direction, then the motor 606 and the bottom cover 609 can be removed, realizing the repair and replacement of the motor 606, and ensuring that the rotation of the rotating rod 602 is not affected by the clamping connection between the motor 606 and the rotating rod 602. When the motor 606 drives the cam 604 to generate multi-directional vibrations, the three symmetrically arranged motors 606 work intermittently, so as to ensure that they do not affect each other, and make the raw materials evenly distributed, and dissipate heat from the work of the motor 606 through the ventilation slot 608. The distance between the double-layer filter screens 308 of the extraction mechanism 3 can be flexibly adjusted, thereby effectively controlling the flow and distribution of the raw materials in the extraction tank 1, making the raw materials evenly disperse in the extraction area, and avoiding local abnormalities; at the same time, the shock excitation mechanism 6 applies multi-directional vibrations to push the raw materials to roll and mix, break the concentration gradient, enhance the contact between the extractant and the raw materials, and comprehensively ensure the extraction is uniform and stable.

[0029] The shock absorption mechanism 7 includes a first bellows 701. The first bellows 701 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. A first clamping ring 703 is threadedly connected inside the extraction tank 1. A second bellows 704 is fixedly connected to the outer surface of the first clamping ring 703. A second filter screen 705 is clamped inside the first clamping ring 703. A second clamping ring 706 is threadedly connected inside the first clamping ring 703. An elastic piece 707 is fixedly connected to the outer surface of the first clamping ring 703. The elastic piece 707 is used to limit the shock absorption mechanism 7.

[0030] The lower surface of the first snap ring 703 is threadedly connected to the outer surface of the opening and closing valve 5. The lower surface of the second snap ring 706 is in contact with the upper surface of the second filter screen 705. The second snap ring 706 is at the top of the second filter screen 705. The outer surface of the elastic sheet 707 is fixedly connected to the outer surface of the bracket 2. The first bellows 701 and the second bellows 704 are used to shock-absorb the top cover 4 and the opening and closing valve 5. By removing the threaded connection between the first snap ring 703 and the extraction tank 1 and making the opening and closing valve 5 threadedly connected to the extraction tank 1 through the stepped groove 702, when the shock-absorbing mechanism 7 is being maintained, the extraction tank 1 can be temporarily sealed to avoid the influence of the outside on the extraction tank 1. The second snap ring 706 is arranged at the top of the second filter screen 705 to prevent the vibration from being transmitted to the second snap ring 706 during shock absorption, causing it to disengage and affecting the opening and closing valve 5.

[0031] The working principle of this embodiment is as follows: When using this coffee extract production device, when adding raw materials, the motor 606 drives the rotating rod 602 to rotate, causing the cam 604 to rotate on the outer surface of the rotating rod 602 and move 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 first cushion block 603. When the cam 604 moves downward and rotates, the rotating rod 602 can be protected by the second cushion block 605. At this time, the raw materials can fall quickly through the vertical vibration to avoid caking, and the raw materials can be evenly distributed in the extraction tank 1 through the horizontal vibration. Through the cooperation of the three groups of shock excitation mechanisms 6 arranged symmetrically, it is ensured that the vibrations of each other do not affect their own vibrations, thereby improving the effect of the shock excitation mechanism 6 on the extraction tank 1. When the motor 606 fails, by rotating the bottom cover 609 in the reverse direction, the bottom cover 609 and the motor 606 are removed for repair and replacement. When cleaning the extraction tank 1, through the multi-directional vibration of the shock excitation mechanism 6, the inner wall of the extraction tank 1 and the upper surface of the arc surface 301 are impacted in all directions to assist in cleaning and ensure the cleanliness of the extraction tank 1. When the shock excitation mechanism 6 performs multi-directional vibration, the telescopic movement of the first bellows 701 protects the top cover 4 and the connected pipeline, and the telescopic movement of the second bellows 704 protects the opening and closing valve 5 and the connected pipeline. The elastic sheet 707 limits the telescopic movement of the first snap ring 703 to keep it within a reasonable range. By rotating the first snap ring 703 in the reverse direction, the shock-absorbing mechanism 7 is removed, and by flipping the second snap ring 706, the replacement of the second filter screen 705 is realized to ensure the quality and efficiency of the secondary filtration of the extract.
