Description

Technical Field

[0001] The utility model relates to the technical field of coffee racks, in particular to an automatic mechanical reciprocating spiral track hand brewing coffee rack. Background Art

[0002] Pour-over coffee has a long history spanning over 100 years. In the traditional pour-over process, a barista carefully pours water in a reciprocating spiral motion over ground coffee, which has been ground to the desired fineness. This pouring of water initiates the brewing process. After sufficient contact and soaking with the water, the flavor-rich coffee gradually flows into a cup placed below the dripper, completing the entire pour-over coffee process.

[0003] However, this traditional operation method of handheld hand brewing has many disadvantages. In terms of water flow stability, since the entire water pouring process relies entirely on the control of the barista's hands, and it is difficult for human hands to be absolutely stable, in actual operation, the hands will inevitably shake slightly. This seemingly insignificant shaking will have a great impact on the water flow. In the initial stage of water pouring, the barista may be able to better control the speed and amount of water flow. However, as the water pouring process continues, the arm muscles gradually fatigue, and the amplitude of hand shaking may increase, which will cause significant differences in the flow rate and flow velocity of the water poured into the coffee powder.

[0004] In addition, the operation of the hand-held hand-pour pot will also bring physical burden to the barista. During the entire hand-pour coffee making process, the barista's hands need to always keep the weight in place to stabilize the hand-pour pot. This is a very labor-intensive process. As the production time increases, the fatigue of the barista's hands will continue to increase, and the pressure on the joints such as the arms and wrists will also become greater and greater. If the barista is in this state for a long time, the joints of the barista are prone to soreness, swelling and other discomfort symptoms, which not only affects the barista's work efficiency, but also poses a potential threat to his or her physical health.

[0005] Therefore, we propose an automatic mechanical reciprocating spiral track hand-poured coffee rack. Utility Model Content

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items. Example

[0033] like Figure 1-7As shown, the utility model provides a technical solution: an automatic mechanical reciprocating spiral track hand-brew coffee rack, comprising a base shell 1, a hand crank 2 is connected to the right side wall of the base shell 1, and the connection of the hand crank 2 is connected to a power input main shaft 3 through two bevel gears, the top of the power input main shaft 3 is connected to a first gear 4, a second gear set 5 is provided at the connection of the first gear 4, a fixed plate 6 is installed on the left side of the second gear set 5, a third gear 7 is installed in the fixed plate 6, a hollow slot 8 is provided at the center of the third gear 7, a filter cup 9 is installed inside the hollow slot 8, and a coffee pot 10 is provided below the filter cup 9, a fourth gear 11 is installed on the power input main shaft 3 and below the first gear 4, a fifth gear 12 is provided at the connection of the fourth gear 11, a rotating shaft 13 is installed at the center of the fifth gear 12, and a sixth gear 14 is provided on the rotating shaft 13 and to the right of the fifth gear 12 , a seventh gear 15 is also provided at the connection of the sixth gear 14, and a screw rod 16 is installed through the seventh gear 15, and a connecting piece 17 is further provided on the screw rod 16 and above the seventh gear 15, and a fixing piece 18 is installed on the top of the connecting piece 17, and an eighth gear 19 is installed on the top of the fixing piece 18, and a ninth gear 20 is provided at the connection of the eighth gear 19, and a tenth gear 21 is installed above the ninth gear 20, and an eleventh gear 22 is installed at the connection of the tenth gear 21 and above the eighth gear 19, and a nut 23 is installed above the eleventh gear 22 and on the screw rod 16. This solution is used for most mechanized hand-brewed pots, filter cups 9, and sharing pots. The machine can complete the reciprocating spiral water flow trajectory that a person holding a pot needs to do, and has a stable and continuously adjustable water flow size and speed, while allowing people to stably control the entire brewing process with the simplest operation method.

[0034] like Figure 1-7 As shown, the utility model provides a technical solution: the second gear set 5 includes a connecting tooth set 51 and a bottom tooth set 52, and the connecting tooth set 51 is connected to the bottom tooth set 52 through a connecting shaft. The parameters such as the length, diameter and surface roughness of the connecting shaft are optimized to ensure that the connection between the connecting tooth set 51 and the bottom tooth set 52 is firm and flexible in rotation.

[0035] The first gear 4 and the connecting tooth set 51 are mutually engaged. This engaging method adopts a special tooth shape design, which can ensure the efficiency and stability of power transmission and avoid slipping or power loss. The bottom tooth set 52 and the third gear 7 are mutually engaged. Similarly, this engaging method also has the characteristics of high precision and high reliability.

[0036] The tooth surfaces of the fourth gear 11, the fifth gear 12, the sixth gear 14 and the seventh gear 15 are all 45° helical teeth. The 45° helical tooth design has many advantages. Compared with straight teeth, helical teeth can provide smoother power transmission during the meshing process and reduce vibration and noise. At the same time, helical teeth have a stronger load-bearing capacity and can adapt to greater power transmission requirements, ensuring the reliability of the entire transmission system.

[0037] The rotation of the rotating shaft 13 can drive the sixth gear 14 to rotate. The sixth gear 14 is connected to the seventh gear 15, which can drive the seventh gear 15 to rotate. In this transmission process, the fitting clearance between each gear is precisely adjusted to ensure the continuity and accuracy of power transmission. The eighth gear 19 and the ninth gear 20 are clamped with each other. The precision of the clamping structure ensures the power transmission efficiency between them. The ninth gear 20 and the tenth gear 21 are fixed to the bearing seat on the coffee rack through a rotating rod. The design of the bearing seat can effectively reduce the friction resistance of the rotating rod during rotation, and provide stable support for the rotating rod, ensuring that the ninth gear 20 and the tenth gear 21 rotate smoothly. The tenth gear 21 and the eleventh gear 22 are clamped with each other. This clamping method is similar to the clamping between other gears, all of which are for achieving stable power transmission.

[0038] A hinge 25 is installed at the top of the screw rod 16. The design of the hinge 25 can realize a flexible connection between the screw rod 16 and other components, allowing a certain degree of angle change to adapt to different movement requirements. A slider 26 is hinged at the connection of the hinge 25, and a fixed seat 27 is installed at the connection of the slider 26. The fixed seat 27 and the slider 26 are slidingly connected. This sliding connection method adopts a high-precision guide rail and slider 26 structure, which can ensure the smooth sliding of the slider 26 on the fixed seat 27, thereby accurately transmitting the linear movement of the screw rod 16 to the fixed seat 27 and the components installed thereon.

[0039] A flushing kettle 28 is installed on the fixed block. The capacity, shape and material of the flushing kettle 28 are carefully designed. The capacity of the flushing kettle 28 is moderate and can meet the water consumption requirements of general hand-brewed coffee; its shape conforms to the principles of fluid mechanics, which helps to ensure the stable outflow of water; the material has good thermal conductivity and corrosion resistance to ensure the service life of the flushing kettle 28 and the quality of coffee brewing. A spout 29 is provided at the connection of the flushing kettle 28. The shape and size of the spout 29 are specially designed to control the shape and speed of the water flow. For example, the inner diameter of the spout 29 gradually becomes smaller, so that the water flow can form a stable trickle when it flows out. A support 30 is installed at the connection of the spout 29. The support 30 can support and limit the spout 29. The structure of the support 30 can effectively prevent the spout 29 from shaking or deflecting during the brewing process, thereby ensuring the accuracy of the water flow trajectory.

[0040] A groove wheel 31 is provided at the connection of the connecting member 17, and a limited sliding groove 32 is provided on the groove wheel 31. A slide fixing point 24 is installed inside the limited sliding groove 32 and on the coffee. The design of the groove wheel 31 and the limited sliding groove 32 can realize a special motion control method. By sliding the slide fixing point 24 in the limited sliding groove 32, the motion trajectory of the connecting member 17 and the components connected thereto can be accurately controlled, thereby further affecting the water flow trajectory and other related parameters during the entire brewing process.

[0041] The working process of the present invention: When using the automatic mechanical reciprocating spiral track hand-brew coffee rack, first, it is necessary to rotate the hand crank 2. Since the connection of the hand crank 2 is connected to the power input main shaft 3 through two bevel gears, the power input main shaft 3 will rotate.

[0042] The power input main shaft 3 drives the first gear 4 to rotate, and the first gear 4 drives the large third gear 7 to rotate through the speed change of the second gear set 5. A hollow slot 8 is provided in the middle of the third gear 7, and the hollow slot 8 can clamp the conical filter cup 9, and then the rotation of the third gear 7 will drive the filter cup 9 to rotate.

[0043] The power input to the main shaft 3 can make the fourth gear 11 rotate. The fourth gear 11 is a forty-five-degree bevel gear that drives the fifth gear 12 to rotate. Since the fifth gear 12 and the sixth gear 14 are connected by the rotating shaft 13, the function of the rotating shaft 13 is to maintain the power input rotation even if the sixth gear 14 moves left and right. Since the sixth gear 14 and the seventh gear 15 are connected, the rotation of the sixth gear 14 will drive the seventh gear 15 to rotate further.

[0044] As the seventh gear 15 rotates, the connecting member 17 is connected to the nut 23 and rotates synchronously. The rotation of the nut 23 causes the screw rod 16 to move vertically upward, lifting the kettle 28.

[0045] The seventh gear 15 simultaneously drives the eighth gear 19 to rotate through the connecting piece 17. The eighth gear 19 drives the eleventh gear 22 to rotate through the ninth gear 20 and the tenth gear 21. The eleventh gear 22 is connected to the groove pulley 31, thereby rotating the groove pulley 31. The limiting sliding groove 32 passes through the sliding groove fixed point 24, and the entire groove pulley 31 will move laterally according to the path of the limiting sliding groove 32. The laterally moving groove pulley 31 will drive the screw rod 16 to move left and right while moving upward, so that the flushing kettle 28 can move upward and left and right at the same time.

[0046] The upward moving screw rod 16 will make an angular movement when the spout 29 and the support member 30 are connected and limited, realizing the pouring action, and the screw rod 16 also moves left and right at the same time, realizing reciprocating motion to the right with the center of the filter cup 9. Under the movement that the filter cup 9 keeps rotating, the reciprocating spiral water flow motion pouring trajectory is completed.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
