Technical Field

[0001] The utility model belongs to the field of coffee machines and relates to the technology of coffee machine funnels, in particular to a powder cake pouring structure for the coffee machine funnel. Background Art

[0002] The funnel of a coffee machine is generally used to hold the powder basket and guide the coffee brewed with hot water into the container; the coffee powder in the powder basket inside the funnel of the coffee machine needs to be evenly compacted before brewing to ensure the contact area between the hot water and the coffee powder, thereby ensuring the taste of the coffee after extraction; the coffee powder after being rinsed with hot water is generally called a powder cake. Before the next extraction, the powder cake needs to be removed and the coffee machine funnel needs to be simply cleaned.

[0003] The reference patent name is: Coffee machine funnel handle powder pouring device (patent announcement number: CN221654070U). The knob on the coffee machine funnel handle controls the up and down movement of the shrapnel inside the coffee machine funnel. The contact between the shrapnel and the powder bowl exerts force on the powder bowl, causing the powder inside the powder bowl to separate from the inner wall of the powder bowl, making it easier to quickly pour out the powder.

[0004] However, when implementing the above technical solution, there are the following problems: the shrapnel structure in the above device is arranged below the powder bowl and inside the coffee machine funnel. When the extracted coffee drips from the powder bowl and flows down along the inner wall of the funnel, it is difficult to avoid contact between the coffee and the surface of the shrapnel and the tension spring inside the coffee machine funnel. Therefore, before extracting coffee, the coffee machine funnel, shrapnel and tension spring need to be completely cleaned, and the shrapnel and tension spring need to be kept dry before and after use to avoid aging, corrosion or contamination of the shrapnel or tension spring, which affects the taste of the coffee. Therefore, the cleaning of the coffee machine funnel is more complicated, and the maintenance and cleaning operations take longer.

[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-6 As shown, a powder cake pouring structure for a coffee machine funnel includes a coffee machine funnel 1 and a powder bowl 2. The coffee machine funnel 1 and the powder bowl 2 are detachably connected. The coffee machine funnel 1 includes a funnel body, a filtering structure and a handle. An auxiliary mechanism is provided inside the coffee machine funnel 1. The auxiliary mechanism includes:

[0029] A plurality of auxiliary blocks 31 are provided, each of which is slidably connected to the interior of the coffee machine funnel 1. The contour of the auxiliary blocks 31 on the side close to the powder bowl 2 is the same as the surface contour of the powder bowl 2 and is elastic. Both ends of the auxiliary blocks 31 on the side close to the powder bowl 2 are streamlined. The auxiliary blocks 31 are arranged in a circular array inside the coffee machine funnel 1. Auxiliary springs 32 are fixedly connected between the auxiliary blocks 31 and the coffee machine funnel 1. A connecting block 33 is fixedly connected to the side of the auxiliary blocks 31 away from the powder bowl 2.

[0030] Inside the coffee machine funnel 1, a plurality of elastic auxiliary blocks 31 are provided, one side of which has the same contour as the powder basket 2. The auxiliary blocks 31 can be moved to fit the powder basket 2 and exert an impact on the powder basket 2. This eliminates the need for the auxiliary blocks 31 to fit the powder basket 2 during coffee extraction, further ensuring space for the coffee to flow after extraction. In addition, the two ends of the auxiliary blocks 31 are designed in a streamlined shape, so that coffee or cleaning water does not accumulate on the surface of the auxiliary blocks 31, thus preliminarily ensuring the cleanliness of the surface of the auxiliary blocks 31.

[0031] A plurality of driving rods 34 and a plurality of connecting rods 35, wherein the driving rods 34 and the connecting rods 35 are fixedly connected to a single connecting block 33, the driving rods 34 are internally slidably connected to the connecting rods 35, and the driving rods 34 and the connecting rods 35 are spaced apart;

[0032] A driving rod 34 and a connecting rod 35 are fixed inside the connecting blocks 33, and the driving rod 34 and the connecting rod 35 are slidably connected to each other. When the position of a single auxiliary block 31 changes, the positions of the other auxiliary blocks 31 can be synchronously driven to change, which makes the operation simpler.

[0033] A connecting belt 36 is fixedly connected to the surface of the auxiliary block 31 near the handle position. A driving column 37 is rotatably connected inside the handle. The other end of the connecting belt 36 is fixedly connected to the surface of the driving column 37. An operating rod 38 is slidably connected inside the driving column 37. A transmission assembly is provided between the driving column 37 and the operating rod 38 to achieve conversion between sliding and rotation. A limiting assembly is provided between the driving column 37 and the handle to limit the position of the driving column 37.

[0034] It should be noted that a fixed transfer column is provided inside the coffee machine funnel 1. When the auxiliary block 31 is stationary, the transfer column is closer to the powder bowl 2 than the connecting block 33. The connecting belt 36 is slidably connected to the side of the transfer column close to the powder bowl 2. When one end of the connecting belt 36 is wrapped around the surface of the driving column 37, the auxiliary block 31 can be driven to move toward the surface of the powder bowl 2.

[0035] The position control path of a certain auxiliary block 31 is guided to the handle position by a connecting belt 36. The sliding of the operating rod 38 inside the handle can cause the auxiliary block 31 to change its position, making it more convenient to hold and operate. A limit assembly is provided to prevent the operating rod 38 from being accidentally touched during coffee extraction, which may change the gap between the powder cakes and affect the taste of the extracted coffee.

[0036] In actual use, the coffee powder dumping structure for the coffee machine funnel 1 is configured such that the auxiliary block 31 that can slide inside the coffee machine funnel 1 impacts the side of the coffee powder bowl 2, causing the coffee powder to be impacted and the side of the coffee powder to be separated from the side wall of the coffee powder bowl 2, thereby facilitating the dumping of the coffee powder. An operating rod 38, a driving column 37, and a connecting belt 36 are provided between the auxiliary block 31 and the handle. The sliding of the operating rod 38 can drive the connecting belt 36 to wrap around the surface of the driving column 37, and then the end of the connecting belt 36 connected to the auxiliary block 31 can drive the auxiliary block 31 to approach the coffee powder bowl 2. The coffee powder can be directly operated through the handle, which is relatively more convenient and simpler to operate.

[0037] In some specific embodiments, the transmission assembly includes a transmission shaft 41 fixed inside the driving column 37. The operating rod 38 has a cross groove 42 on its surface. The transmission shaft 41 is adapted to fit into the cross groove 42. The cross groove 42 has three intersection points on the surface of the driving column 37, and adjacent intersection points are located on different sides of the transmission shaft 41.

[0038] In some specific embodiments, the above-mentioned limit assembly includes a limit block 51 and a pressing block 52 slidably disposed inside the handle. The surfaces of the limit block 51 and the pressing block 52 are rotatably connected to a limit rod 53. A fixing rod 54 is fixedly connected inside the handle. The fixing rod 54 is rotatably connected to the center of the limit rod 53. A limit spring 55 is fixedly connected between the pressing block 52 and the handle.

[0039] In a further embodiment, the width of the limiting block 51 and the pressing block 52 is the same as the diameter of the driving column 37, and the distance between the limiting block 51 and the pressing block 52 is greater than the length of the driving column 37; a sliding ring 56 is fixedly connected to the side of the limiting block 51 and the pressing block 52 away from the powder bowl 2, and sliding columns 57 are fixedly connected to both ends of the limiting rod 53, and the sliding ring 56 and the sliding column 57 are adapted;

[0040] The working principle of the present invention is as follows: fix the powder bowl 2 to the inside of the coffee machine funnel 1, fix the coffee machine funnel 1 on the coffee machine, extract coffee, and after the coffee is extracted, invert the coffee machine funnel 1 at the specified position, and then press the pressing block 52 to the inside of the handle. The pressing block 52 slides, prompting the limit rod 53 to rotate at a fixed point, driving the limit block 51 at the other end to slide, and the surface of the limit block 51 is disengaged from one end of the operating rod 38. Press the operating rod 38, and the sliding of the operating rod 38 causes the driving column 37 to rotate through the cross groove 42 and the transmission shaft 41. The rotation of the driving column 37 causes the connecting belt 36 to wind around, pulling the auxiliary block 31. The sliding of a single auxiliary block 31 drives all the auxiliary blocks 31 to move toward the surface of the powder bowl 2 through the driving rod 34 and the connecting rod 35, causing an impact on the side wall of the powder bowl 2, making the powder cake more likely to fall off.

[0041] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
