Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and particularly relates to a brewing cup moving and changing position sliding mechanism for a semi-automatic bean grinding coffee machine. Background Art

[0002] For fully automatic coffee machines with a bean grinding function sold on the market, users only need to load the coffee beans and then press the start button, and the fully automatic coffee machine can automatically complete all processes from grinding, powder loading, powder pressing, brewing, coffee liquid discharging, to residue discharging. However, the structure of the fully automatic coffee machine is very complex and the price is very expensive. A semi-automatic bean grinding coffee machine means that except for the residue discharging process which is manually completed by the user, the rest of the processes are automatically completed by the coffee machine. The basic structure of the semi-automatic bean grinding coffee machine is as follows: it includes a frame, and a bean grinding mechanism, a powder pressing and brewing mechanism, a coffee brewing cup, a brewing cup bracket, and a brewing cup powder loading - powder pressing and brewing moving and changing position mechanism arranged on the frame. The bean grinding mechanism is located at the top of the frame, and is sequentially arranged from top to bottom with the powder pressing and brewing mechanism and the sliding mechanism. A powder outlet pipe extending laterally is provided at the bottom of the bean grinding mechanism; the brewing cup powder loading - powder pressing and brewing moving and changing position mechanism can be a swinging mechanism or a gear and rack mechanism driven by a motor as shown in "Coffee Automatic Brewing Machine and Coffee Automatic Brewing Method" of CN202411656355.6 (as shown in...). Figure 3 shown). The gear and rack mechanism is arranged below the powder pressing and brewing mechanism. The brewing cup bracket is arranged on the rack, and the gear meshing with the rack is rotated forward and backward by a driving motor, so as to realize the reciprocating movement of the brewing cup between the powder loading position under the powder outlet pipe and the position under the powder pressing and brewing changing position mechanism. Figure 1 shown).

[0003] The above-mentioned moving and changing position mechanism that drives the brewing cup to move by a motor driving a gear and rack must rely on the motor as the power, its structure is relatively complex, and the installation accuracy requirements for the gear and rack are relatively high. This directly leads to high manufacturing costs of the coffee machine and high daily maintenance difficulty. Summary of the Invention

[0004] Aiming at the above defects, the purpose of the present invention is to propose a semi-automatic coffee machine with a more concise structure and lower manufacturing cost.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A semi-automatic bean grinding coffee machine includes a frame, and a bean grinding mechanism, a powder pressing and brewing mechanism, and a brewing cup changing position sliding mechanism arranged on the frame; the bean grinding mechanism is located at the top of the frame;

[0007] The bean grinding mechanism, the powder pressing and brewing mechanism, and the brewing cup changing position sliding mechanism are sequentially arranged from top to bottom, and a powder outlet pipe extending laterally is provided at the bottom of the bean grinding mechanism;

[0008] The brewing cup transposition sliding mechanism includes a sliding component and a brewing cup bracket. The brewing cup bracket is installed on the sliding component, and the brewing cup is detachably placed on the brewing cup bracket.

[0009] The end of the powder outlet pipe faces downward and corresponds to a point on the sliding track of the brewing cup bracket, which is the powder receiving position. The powder pressing and brewing mechanism faces downward and corresponds to another point on the sliding track of the brewing cup bracket, which is the brewing position. The brewing cup bracket reciprocates between the powder receiving position and the brewing position by sliding.

[0010] Preferably, the sliding component is composed of a slider and a fixed rail. The fixed rail is fixed to the machine frame, the slider is slidably assembled with the fixed rail, and the brewing cup bracket is installed on the slider.

[0011] A brewing cup restraint device is provided at the position of the machine frame corresponding to the powder receiving position. When the brewing cup bracket moves to the powder receiving position, the sliding freedom degree of the brewing cup bracket is restricted by the brewing cup restraint device.

[0012] The brewing cup restraint device is an electromagnet adsorption device, and a metal part is provided at the position of the brewing cup bracket adapted to the electromagnet adsorption device.

[0013] Or, the brewing cup restraint device is a telescopic bolt, and a bolt hole is provided at the position of the brewing cup bracket adapted to the telescopic bolt.

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

[0015] Preferably, the fixed rail is arranged between the left and right side plates of the machine frame, and the slider slides horizontally along the fixed rail.

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

[0017] Furthermore, the fixed rail is installed horizontally.

[0018] Furthermore, the fixed rail is installed obliquely, and one end of the powder receiving position is higher than the powder pressing and brewing position end.

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

[0020] Furthermore, the end point of the sliding stroke of one end of the sliding component is the brewing position, and the end point of the sliding stroke of 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 bean grinding coffee machine provided by the present solution has two corresponding workstations for the bean grinding mechanism and the brewing mechanism respectively, and the two workstations are connected by a sliding brewing cup holder. Compared with the prior art, the brewing cup holder of the present solution does not use power drive, so the production and maintenance costs are relatively low; when in use, the brewing cup holder is moved along the sliding mechanism by moving the brewing cup holder, compared with the existing coffee machine without a sliding mechanism and a brewing cup holder, the action of lifting and inserting the brewing cup into the grinding mechanism and the brewing mechanism is reduced, so it will be more convenient to use.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

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

[0030] The bean grinding mechanism 200, the powder pressing and brewing mechanism 300 and the brewing cup shifting and sliding mechanism 400 are arranged in sequence from top to bottom, and a powder outlet pipe 210 extending laterally is provided at the bottom of the bean grinding mechanism 200;

[0031] The brewing cup transposition sliding mechanism 400 includes a sliding assembly 410 and a brewing cup bracket 420. The brewing cup bracket 420 is mounted on the sliding assembly 410. The brewing cup can be detachably placed on the brewing cup bracket 420.

[0032] The end of the powder outlet pipe 210 points downwards to a point on the sliding track of the brewing cup holder 420, which is the powder receiving position; the powder pressing and brewing mechanism 300 points downwards to another point on the sliding track 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 bean grinding coffee machine provided by the present solution has two corresponding workstations for the bean grinding mechanism and the brewing mechanism respectively, and the two workstations are connected by a sliding brewing cup holder. Compared with the prior art, the brewing cup holder of the present solution does not use a driving mechanism as a power source, so the production and maintenance costs are relatively low; when in use, the brewing cup holder is moved along the sliding mechanism 400 by moving the brewing cup holder, compared with the existing coffee machine without the sliding mechanism 400 and the brewing cup holder, the actions of lifting and inserting the brewing cup into the grinding mechanism and the brewing mechanism are 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, and the brewing cup holder 420 is installed on the slider 411;

[0035] A brewing cup restraint device is provided at a position of the frame 100 corresponding to the powder receiving position. When the brewing cup holder 420 moves to the powder receiving position, the sliding freedom of the brewing cup holder 420 is restrained by the brewing cup restraint device.

[0036] The brewing cup restraining device is an electromagnet adsorption device, and a metal piece is provided at a position where the brewing cup bracket 420 and the electromagnet adsorption device are adapted;

[0037] Alternatively, the brewing cup restraining device is a telescopic latch, and a pin hole is provided at a position where the brewing cup bracket 420 matches the telescopic latch.

[0038] When the sliding component 410 slides to the powder receiving position, the brewing cup restraint device restrains the sliding freedom degree of the brewing cup bracket 420, so that the position of the brewing cup bracket 420 is maintained at the powder receiving position; after the powder receiving is completed, the brewing cup restraint device releases the restraint on the sliding freedom degree of the brewing cup bracket 420, and at this time, the brewing cup bracket 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 a ball guide rail and a roller guide rail, and has the characteristics of small frictional resistance and strong load-bearing capacity, which is beneficial to the movement of the brewing cup bracket 420.

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

[0042] This method is to horizontally arrange the fixed rail 412 on the frame. The corresponding brewing position and powder pressing position are also horizontally arranged and can be set by horizontal translation. The brewing position and the powder pressing position are arranged side by side.

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

[0044] This method is to horizontally rotate the fixed rail 412 by 90 degrees relative to the previous method and arrange it longitudinally on the frame. The corresponding brewing position and powder pressing position are also longitudinally arranged. The brewing cup bracket 420 can be designed in a drawer type, and the brewing position and the powder pressing position are arranged front and back.

[0045] Such as Figure 4 As shown, the fixed rail 412 is horizontally installed.

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

[0047] In addition, the fixed rail 412 is inclinedly installed, and one end of the powder receiving position is higher than the end of the powder pressing and brewing position.

[0048] When the fixed rail 412 is inclinedly installed, the brewing cup bracket 420 will slide to the brewing position by its own gravity without restraint.

[0049] Such as Figure 5 As shown, a return spring 500 is arranged between the brewing cup bracket 420 and the inner wall of the frame 100 at the powder pressing and brewing end.

[0050] Through the return spring 500, the brewing cup bracket 420 will remain below the brewing position under natural conditions.

[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 end points of the sliding assembly 410 are set as brewing positions and powder receiving positions to facilitate the positioning of the brewing cup holder 420.

[0053] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
