Description

Technical Field

[0001] The present invention relates to grinding equipment technology, in particular to a grinding equipment for a coffee machine. Background Art

[0002] A coffee machine is a device used to make coffee, typically consisting of one or more heaters, a grinder, a coffee pot, and a filter. As people's quality of life improves, coffee machines are becoming increasingly popular. They automate the entire coffee brewing process, from grinding and pressing to filling, brewing, and removing grounds, making them convenient to use.

[0003] Coffee is a beverage made from roasted and ground coffee beans. As one of the world's three major beverages, it's a staple alongside cocoa and tea. Coffee beans are roasted in various ways. Once ground, they can be brewed or boiled directly. The grind level can be adjusted to coarse, medium, fine, or extra-fine, with a wide range of adjustments.

[0004] Chinese patent publication number CN216988007U discloses a special grinding device for sugar-roasted coffee beans with adjustable particle size. The special grinding device for sugar-roasted coffee beans with adjustable particle size has a crushing tube driven by the motor output shaft to rotate at high speed inside the device housing to perform preliminary crushing of the raw materials. The raw materials preliminarily crushed by the crushing tube fall into the gap between the crushing block and the force plate and are ground and crushed. Rotating the T-shaped screw can adjust the position of the force plate and control the size of the gap between the crushing block and the force plate. The gap between the force plate and the crushing block can be adjusted as needed to ensure that the particle size of the raw materials processed by the device housing meets the requirements and ensure flexible and efficient operation inside the device housing.

[0005] When using existing equipment, the overall structure is relatively complex or uneven coarseness and fineness are easily caused during grinding, resulting in a poor user experience. At the same time, during grinding, the powder is easily adsorbed on the wall of the cylinder and cannot be quickly cleaned, which affects the quality of subsequent coffee when grinding.

For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Example: See Figures 1-8 A grinding device for a coffee machine includes a processing cylinder 1, the outer surface of the processing cylinder 1 is provided with a protective block 11, and the inner cavity of the processing cylinder 1 is provided with a processing component 2, through which coffee beans are ground.

[0039] In this solution, the protective block 11 is used to limit the processing cylinder 1. The protective block 11 can fix the processing cylinder 1 in a suitable position and cooperate with the processing component 2 to grind the coffee beans.

[0040] Furthermore, the processing assembly 2 includes a support plate 21 connected to the processing cylinder 1. A driving member 22 is provided at the lower end of the inner wall of the processing cylinder 1. A grinding block 23 is provided at the output end of the driving member 22, and the outer surface of the grinding block 23 is in contact with the inner wall of the support plate 21. The support plate 21 has an arc-shaped cross-section, and a through hole 211 is provided in the middle of the end of the support plate 21. The inner wall of the through hole 211 is in contact with the outer surface of the grinding block 23.

[0041] In this embodiment, the driving member 22 is a device with power output, such as a motor, and is connected to an external control device. When the driving member 22 is started, it synchronously drives the grinding block 23 arranged at its output end to rotate, and the grinding block 23 fits with the inner wall of the through hole 211, thereby further grinding the coffee powder until the coffee powder meets the standards.

[0042] The lower end of the support plate 21 is provided with a device with a telescopic function, such as an electric telescopic rod, and is connected to an external control device. The electric telescopic rod can drive the support plate 21 to move up and down, thereby adjusting the gap between the through hole 211 and the grinding block 23, so that the ground coffee powder meets the specified standard.

[0043] Furthermore, a telescopic member 242 is provided at the upper end of the grinding block 23 , and a movable block 241 is provided at the output end of the telescopic member 242 . The outer surface of the movable block 241 is provided with multiple groups of grooves 244 , and the multiple groups of grooves 244 are evenly distributed on the outer surface of the movable block 241 .

[0044] Specifically, the telescopic member 242 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. At the same time, when the telescopic member 242 is started, it drives the movable block 241 set at its output end to move, and the groove 244 on the outer surface of the movable block 241 is engaged with the protrusion 243 on the inner wall of the sleeve 24, thereby driving the sleeve 24 to rotate.

[0045] Furthermore, a base plate 25 is rotatably mounted on the upper end of the movable block 241, and a ring 26 is rotatably mounted on the inner wall of the base plate 25. Both the ring 26 and the inner wall of the base plate 25 are provided with a sleeve 24, and the inner wall of the sleeve 24 is provided with a protrusion 243 corresponding to the groove 244, and the outer surface of the protrusion 243 is slidably connected to the inner wall of the groove 244.

[0046] Specifically, when the sleeve 24 connected to the ring 26 rotates, the ring 26 is driven to rotate. When the movable block 241 moves to the inner wall of the sleeve 24 connected to the bottom plate 25, the bottom plate 25 is driven to rotate as a whole.

[0047] The lower end of the base plate 25 is connected to the upper end of the support plate 21 through a support column. At the same time, the support column is slidably connected to the lower end of the base plate 25, so that when the base plate 25 rotates, the support column supports the base plate 25 to ensure the stability of the base plate 25 during rotation.

[0048] Furthermore, multiple groups of adjustment blocks 27 are rotatably mounted on the end of the circular ring 26 , and the multiple groups of adjustment blocks 27 are evenly distributed on the end of the circular ring 26 , while the ends of the adjustment blocks 27 penetrate and extend to the outside of the bottom plate 25 .

[0049] Specifically, when the ring 26 rotates, the adjusting block 27 mounted on the ring 26 is synchronously driven to move, and at the same time, the length of the adjusting block 27 extended is adjusted according to the actual situation to make it suitable for the current scene.

[0050] Furthermore, a fixing ring 28 is provided on the inner wall of the bottom plate 25 , and a limiting rod 29 corresponding to the adjustment block 27 is rotatably mounted on the end of the fixing ring 28 , and the end of the limiting rod 29 is rotatably connected to the outer surface of the adjustment block 27 .

[0051] Specifically, as the adjustment block 27 moves, it cooperates with the limiting rod 29 to restrain it. As the adjustment block 27 rotates with the ring 26, it rotates around the connection point of the limiting rod 29 and slowly expands outward until it reaches the desired position. The outer surface of the adjustment block 27 is blade-shaped and is used for preliminary grinding of coffee beans.

[0052] The outer surface of the bottom plate 25 is provided with a slot, which limits the adjustment block 27. At the same time, the inner wall of the slot is provided with a sealing component such as rubber, thereby dividing the inside and outside of the bottom plate 25.

[0053] Furthermore, a cleaning assembly 3 is mounted on the upper end of the base plate 25. This assembly cleans residue from the inner wall of the treatment drum 1. The cleaning assembly 3 includes a cover plate 31 connected to the treatment drum 1. A telescopic rod 32 is disposed at the lower end of the cover plate 31, and a fixing plate 321 is disposed at the lower end of the telescopic rod 32. The lower end of the fixing plate 321 is engaged with the upper end of the base plate 25.

[0054] In this embodiment, a snap-in groove is provided at the lower end of the fixed plate 321, which is rotatably connected to the outer surface of the upper end of the base plate 25 through the snap-in groove, so that when the base plate 25 rotates, the cleaning assembly 3 remains stable. At the same time, a clamp or other fixing component is provided on the outer surface of the cover plate 31, so that when the cover plate 31 is in contact with the upper end of the processing cylinder 1, the stability of the cover plate 31 is ensured.

[0055] Furthermore, a positioning rod 36 is provided at the middle position of the upper end of the fixing plate 321 , and a slide cylinder 37 is slidably mounted on the outer surface of the positioning rod 36 .

[0056] Specifically, the positioning rod 36 is used to limit the slide 37 and provide a moving track for the slide 37, thereby preventing the slide 37 from falling off.

[0057] Furthermore, multiple sets of support plates 34 are slidably mounted on the outer surface of the slide 37, and the multiple sets of support plates 34 are evenly distributed on the outer surface of the slide 37. The lower end of the cover 31 is rotatably mounted with an extrusion rod 33 corresponding to the support plate 34, and the outer surface of the extrusion rod 33 is rotatably connected to the end of the support plate 34.

[0058] Specifically, when the slide 37 moves, the support plate 34 provided on its outer surface is synchronously driven to move, and the extrusion rod 33 is supported by the support plate 34. When the support plate 34 moves following the slide 37, the extrusion rod 33 is driven to rotate around the connection with the cover plate 31, so that the end of the extrusion rod 33 away from the cover plate 31 expands outward or moves toward the middle.

[0059] Furthermore, an arc-shaped plate 35 is rotatably mounted on the end of the extrusion rod 33 , and the outer surface of the arc-shaped plate 35 is slidably connected to the inner wall of the treatment cylinder 1 .

[0060] Specifically, since the arc plate 35 is rotatably mounted on the end of the extrusion rod 33 and the arc plate 35 is in contact with the inner wall of the treatment cylinder 1 , the extrusion rod 33 limits the arc plate 35 to ensure its stability.

[0061] The outer surface of the synchronous arc plate 35 is provided with a sealing component such as rubber, so that when the coffee powder remaining on the inner wall of the processing cylinder 1 is cleaned by the arc plate 35, no coffee powder residue will be generated again.

[0062] Furthermore, an elastic member 38 is provided at the end of the slide cylinder 37 , and one end of the elastic member 38 away from the slide cylinder 37 is connected to the lower end of the cover plate 31 .

[0063] Specifically, the elastic member 38 is an elastic member such as a spring, which supports the slide 37 to ensure that the slide 37 is always in a taut state and cleans the residues tightly attached to the inner wall of the treatment cylinder 1.

[0064] Furthermore, a guide hole 12 is provided at the lower end of the outer surface of the processing cylinder 1 , through which the processed coffee powder is extracted.

[0065] Specifically, the inner wall of the outlet hole 12 is provided with a sealing component such as a plug, so that when the coffee beans are ground, the sealing inside the processing cylinder 1 is ensured to prevent the coffee powder from flowing out directly.

[0066] In this embodiment, a corresponding control device can be provided for use in conjunction with the control device. The control device can select any controller to be connected to the electrical components in this application, thereby controlling the opening and closing operations of each electrical component. This part is the prior art. Here, a single-chip microcomputer can be provided as a control device for demonstration. The single-chip microcomputer in this embodiment is a typical embedded microcontroller (MicrocontrollerUnit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware required) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0067] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
