Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a brewing cup moving and repositioning sliding mechanism for a semi-automatic coffee machine. Background Technology

[0002] Fully automatic coffee machines with a grinding function sold on the market only require the user to load coffee beans and press the start button. The machine can automatically complete all processes from grinding, loading, tamping, brewing, dispensing coffee, and removing grounds. However, fully automatic coffee machines have a very complex structure and are very expensive. Semi-automatic coffee machines, on the other hand, are automated except for the grounds removal process, which is performed manually by the user. The basic structure of a semi-automatic coffee machine includes a frame, and on the frame, a grinding mechanism, a tamping and brewing mechanism, a coffee brewing cup, a brewing cup holder, and a coffee loading-tamping-brewing movement mechanism. The grinding mechanism is located at the top of the frame and is arranged sequentially from top to bottom with the tamping and brewing mechanism and the sliding mechanism. The bottom of the grinding mechanism has a side-extending powder outlet tube. The coffee loading-tamping-brewing movement mechanism can be a swing mechanism or a similar mechanism as described in CN202411656355.6 "Automatic Coffee Brewing Machine and Automatic Coffee Brewing Method". Figure 3 The gear and rack mechanism driven by the motor shown (e.g.) Figure 1 (As shown). The gear and rack mechanism is located below the powder pressing and brewing mechanism, and the brewing cup holder is mounted on the rack. The gear meshing with the rack is driven by a drive motor to rotate forward and backward, thereby realizing the reciprocating movement of the brewing cup between the powder filling position under the powder outlet pipe and the position under the powder pressing and brewing switching mechanism.

[0003] The aforementioned shifting mechanism, which uses a motor to drive a rack and pinion to move the brewing cup, relies on a motor for power. Its structure is relatively complex, and the installation precision of the rack and pinion is crucial. This directly contributes to the high manufacturing cost of coffee machines and the difficulty of routine maintenance. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to propose a semi-automatic coffee machine with a simpler structure and lower manufacturing cost.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A semi-automatic coffee machine includes a frame, and a grinding mechanism, a tamping and brewing mechanism, and a brewing cup shifting and sliding mechanism disposed on the frame; the grinding mechanism is located at the top of the frame;

[0007] The grinding mechanism, the tamping and brewing mechanism, and the brewing cup switching and sliding mechanism are arranged in sequence from top to bottom. The bottom of the grinding mechanism is provided with a powder outlet tube that extends laterally.

[0008] The brewing cup switching sliding mechanism includes a sliding component and a brewing cup holder. The brewing cup holder is installed on the sliding component, and the brewing cup can be detachably placed on the brewing cup holder.

[0009] The end of the powder dispensing tube faces downwards and corresponds to a point on the sliding trajectory of the brewing cup holder, which is the powder receiving position; the powder pressing and brewing mechanism faces downwards and corresponds to another point on the sliding trajectory of the brewing cup holder, which is the brewing position; the brewing cup holder moves back and forth between the powder receiving position and the brewing position by sliding.

[0010] Preferably, the sliding assembly consists of a slider and a fixed rail, the fixed rail is fixed to the frame, the slider and the fixed rail are slidably assembled, and the brewing cup holder is installed on the slider;

[0011] The frame is equipped with a brewing cup constraint device at the position corresponding to the powder receiving position. When the brewing cup holder moves to the powder receiving position, the sliding degree of freedom of the brewing cup holder is constrained by the brewing cup constraint device.

[0012] The brewing cup restraint device is an electromagnet adsorption device, and a metal part is provided at the position where the brewing cup holder is adapted to the electromagnet adsorption device;

[0013] Alternatively, the brewing cup restraint device may be a telescopic pin, and the brewing cup holder may have a pin hole at the position where it is adapted to the telescopic pin.

[0014] Preferably, the sliding component is a rolling guide rail.

[0015] Preferably, the guide rail is disposed between the left and right side plates of the frame, and the slider slides laterally along the guide rail.

[0016] Furthermore, the guide rail is disposed between the front and rear side plates of the frame, and the slider slides longitudinally along the guide rail.

[0017] Furthermore, the track is installed horizontally.

[0018] Furthermore, the track is installed at an angle, with one end of the powder receiving position higher than the powder pressing and brewing position.

[0019] Furthermore, a return spring is provided between the brewing cup holder and the inner wall of the frame of the powder brewing end.

[0020] Furthermore, the end point of the sliding stroke at one end of the sliding component is the brewing position, and the end point of the sliding stroke at the other end of the sliding component is the powder receiving position.

[0021] One of the above technical solutions includes the following beneficial effects: The semi-automatic coffee machine provided by this solution has two corresponding workstations for the grinding mechanism and the brewing mechanism, and the two workstations are connected by a sliding brewing cup holder. Compared with the prior art, the brewing cup holder of this solution does not use a power drive, so the production and maintenance costs are relatively low. In use, the brewing cup holder is moved along the sliding mechanism by pushing it. Compared with the existing coffee machines without a sliding mechanism and brewing cup holder, the action of the brewing cup in lifting and locking into the grinding mechanism and the brewing mechanism is reduced, so it is more convenient to use.

[0027] The components include: frame 100, grinding mechanism 200, powder outlet pipe 210, powder pressing and brewing mechanism 300, brewing cup changing sliding mechanism 400, sliding component 410, slider 411, fixed rail 412, brewing cup holder 420, and return spring 500. Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figure 1 As shown, a semi-automatic coffee machine includes a frame 100, and a grinding mechanism 200, a tamping and brewing mechanism 300, and a brewing cup shifting and sliding mechanism 400 disposed on the frame 100; the grinding mechanism 200 is located at the top of the frame 100.

[0030] The grinding mechanism 200, the powder pressing and brewing mechanism 300 and the brewing cup switching and sliding mechanism 400 are arranged sequentially from top to bottom. The bottom of the grinding mechanism 200 is provided with a powder outlet pipe 210 extending laterally.

[0031] The brewing cup switching sliding mechanism 400 includes a sliding component 410 and a brewing cup holder 420. The brewing cup holder 420 is installed on the sliding component 410, and the brewing cup can be detachably placed in the brewing cup holder 420.

[0032] The end of the powder outlet tube 210 faces downwards and corresponds to a point on the sliding trajectory of the brewing cup holder 420, which is the powder receiving position; the powder pressing and brewing mechanism 300 faces downwards and corresponds to another point on the sliding trajectory of the brewing cup holder 420, which is the brewing position; the brewing cup holder 420 is connected between the powder receiving position and the brewing position by sliding.

[0033] The semi-automatic coffee machine provided in this solution has two corresponding workstations for the grinding mechanism and the brewing mechanism, and the two workstations are connected by a sliding brewing cup holder. Compared with the existing technology, the brewing cup holder in this solution does not use a drive mechanism, so the production and maintenance costs are relatively low. In use, the brewing cup holder is moved along the sliding mechanism 400 by moving it. Compared with the existing coffee machines that do not have a sliding mechanism 400 and a brewing cup holder, the movement of the brewing cup in lifting and locking into the grinding mechanism and the brewing mechanism is reduced, so it is more convenient to use.

[0034] like Figure 3 As shown, the sliding assembly 410 is composed of a slider 411 and a fixed rail 412. The fixed rail 412 is fixed to the frame 100. The slider 411 and the fixed rail 412 are slidably assembled. The brewing cup holder 420 is installed on the slider 411.

[0035] The frame 100 is provided with a brewing cup constraint device at the position corresponding to the powder receiving position. When the brewing cup holder 420 moves to the powder receiving position, the sliding degree of freedom of the brewing cup holder 420 is constrained by the brewing cup constraint device.

[0036] The brewing cup restraint device is an electromagnet adsorption device, and the brewing cup holder 420 is provided with a metal part at the position that is compatible with the electromagnet adsorption device.

[0037] Alternatively, the brewing cup restraint device may be a telescopic pin, and the brewing cup holder 420 may have a pin hole at the position where it is adapted to the telescopic pin.

[0038] When the sliding component 410 slides to the powder receiving position, the brewing cup constraint device constrains the sliding degree of freedom of the brewing cup holder 420, keeping the position of the brewing cup holder 420 at the powder receiving position; after the powder is received, the brewing cup constraint device will release the constraint on the sliding degree of freedom of the brewing cup holder 420, at which point the brewing cup holder 420 can be moved to the brewing position for brewing in various ways.

[0039] In addition, the sliding component 410 is a rolling guide rail.

[0040] The rolling guide rail is specifically one of the ball guide rails and roller guide rails. It has the characteristics of low frictional resistance and high load-bearing capacity, which is beneficial to the movement of the brewing cup holder 420.

[0041] In addition, the fixed rail 412 is disposed between the left and right side plates of the frame 100, and the slider 411 slides laterally along the fixed rail 412.

[0042] This method involves setting the fixed rail 412 horizontally on the frame. The corresponding brewing and pressing positions are also set horizontally and can be set by horizontal translation. The brewing and pressing positions are set side by side.

[0043] The fixed rail 412 is disposed between the front and rear side plates of the frame 100, and the slider 411 slides longitudinally along the fixed rail 412.

[0044] In this method, the fixed rail 412 is rotated 90 degrees horizontally relative to the previous method and set longitudinally on the frame. The brewing position and the powder pressing position are also set longitudinally. The brewing cup holder 420 can be designed in a drawer-type manner, with the brewing position and the powder pressing position set front and back.

[0045] like Figure 4 As shown, the track 412 is installed horizontally.

[0046] When the guide rail 412 is installed horizontally, the brewing cup holder 420 will remain in place without external force.

[0047] In addition, the guide rail 412 is installed at an angle, with one end of the powder receiving position higher than the powder pressing and brewing position.

[0048] When the guide rail 412 is installed at an angle, the brewing cup holder 420 will slide to the brewing position by its own weight without any restraint.

[0049] like Figure 5 As shown, a return spring 500 is provided between the brewing cup holder 420 and the inner wall of the frame 100 of the powder brewing end.

[0050] The return spring 500 ensures that the brewing cup holder 420 remains below the brewing position under normal circumstances.

[0051] The end point of the sliding stroke at one end of the sliding component 410 is the brewing position, and the end point of the sliding stroke at the other end of the sliding component 410 is the powder receiving position.

[0052] The two ends of the sliding component 410 are set as the brewing position and the powder receiving position, which facilitates the positioning of the brewing cup holder 420.

[0053] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
