Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of coffee brewing machines, and in particular to a water injection angle adjusting structure and a coffee brewing machine. BACKGROUND

[0002] With the increasing popularity of coffee, the demand for coffee brewing machines is also growing. However, the traditional coffee brewing machine has poor coffee powder brewing uniformity and low brewing efficiency because the water outlet is only aimed at the center of the filter cup. To address these challenges, some manufacturers have made further research and development.

[0003] The prior art such as patent CN201888696U proposes an improved structure of a coffee machine, which mainly has a machine body including an eave part and upper and lower seats, a driving mechanism for forward and backward displacement is arranged in the eave part, and a water injection pipe connected to a water tank is arranged in the driving mechanism. The upper seat is provided with a rotating mechanism including a supporting rack. The filter cup containing coffee powder is placed on the supporting rack, the rotation of the filter cup is driven by the rotating mechanism, and the forward and backward displacement of the water injection pipe is driven by the driving mechanism, so that the hot water in the water tank is injected into the filter cup from the center to the outside in a vortex path. After uniform brewing of the coffee powder, it flows into the container placed in the lower seat, thereby improving the brewing uniformity and brewing efficiency of the coffee brewing machine.

[0004] However, the coffee machine described above changes the water injection position by driving the water injection pipe to move forward and backward relative to the machine body, so that the coffee machine described above needs a larger space for adjustment, which increases the volume of the coffee machine described above and greatly reduces the portability of the coffee machine described above. At the same time, since the water injection angle of the water injection pipe is fixed during the adjustment of the coffee machine described above, the coffee machine described above is only suitable for filter cups of specific shapes and sizes, so that the coffee machine described above has poor applicability.

[0038] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0039] like Figures 1 to 9 As shown, in one embodiment, a water injection angle adjustment structure 100 is installed in the water inlet chamber 210 of the brewing component 200 of the coffee brewing machine 10. The water injection angle adjustment structure 100 includes an adjustment component 110 and an elastic water injection element 120. The adjustment component 110 is installed in the water inlet chamber 210 and includes a fixing member 111 and a movable member 112. The fixing member 111 is installed and fixed in the water inlet chamber 210, and the movable member 112 is slidably connected to the fixing member 111. The movable member 112 has a positioning hole 1121. The first end of the elastic water injection member 120 is connected to the water inlet 220 of the brewing assembly 200. The second end of the elastic water injection member 120 passes through the positioning hole 1121 and is disposed at the recessed water outlet 230 of the brewing assembly 200. The recessed water outlet 230 can provide movement space for the second end of the elastic water injection member 120, so that when the movable member 112 slides relative to the fixed member 111, the movable member 112 can drive the elastic water injection. The second end of component 120 moves relative to the first end of the elastic water inlet component 120, allowing the coffee brewing machine 10 to adjust the water inlet angle of the elastic water inlet component 120 via the adjusting component 110. This allows the water inlet angle of the elastic water inlet component 120 to change back and forth when the movable component 112 drives the second end of the elastic water inlet component 120 to oscillate relative to the first end, thus enabling the coffee brewing machine 10 to evenly brew the coffee powder in the container and improve the brewing effect. Compared to the improved coffee machine structure in the aforementioned related technologies, which uses a drive structure to move the entire water inlet pipe forward and backward relative to the machine body 300 to change the water inlet position, the water inlet angle adjustment structure 100 of this disclosure, which adjusts the angle of the elastic water inlet component 120 via the adjusting component 110, effectively reduces the installation space, reduces the overall size of the coffee brewing machine 10, and greatly improves the portability of the coffee brewing machine 10 of this disclosure.

Compared with the improved structure of the coffee maker in the related art, the design of the water injection angle adjusting structure 100 of the present disclosure adjusts the angle of the elastic water injection part 120 through the adjusting assembly 110, which can effectively reduce the installation space and reduce the overall volume of the coffee maker 10, thereby greatly improving the portability of the coffee maker 10 of the present disclosure.

The coffee maker 10 described above, since the adjusting assembly 110 is used to be mounted in the water conveying cavity 210, the adjusting assembly 110 comprises a fixed member 111 and a movable member 112, the fixed member 111 is used to be fixedly mounted in the water conveying cavity 210, the movable member 112 is slidingly connected to the fixed member 111, the movable member 112 is formed with a positioning hole 1121, the first end of the elastic water injection member 120 is used to be communicated with the water inlet 220 of the brewing assembly 200, the second end of the elastic water injection member 120 is passed through the positioning hole 1121 and is used to be arranged at the avoiding water outlet 230 of the brewing assembly 200, the avoiding water outlet 230 can provide a moving space for the second end of the elastic water injection member 120, so that when the movable member 112 slides relative to the fixed member 111, the movable member 112 can drive the second end of the elastic water injection member 120 to move relative to the first end of the elastic water injection member 120, so that the coffee maker 10 can adjust the water injection angle of the elastic water injection member 120 through the adjusting assembly 110, and then when the movable member 112 drives the second end of the elastic water injection member 120 to reciprocally move relative to the first end of the elastic water injection member 120, the water injection angle of the elastic water injection member 120 can change back and forth, so that the coffee maker 10 can uniformly brew the coffee powder in the container, so as to improve the brewing effect of the coffee. Compared with the improvement structure of the coffee maker in the above-mentioned related art, which changes the water injection position by driving the whole water injection pipe to move forward and backward relative to the machine body 300, the angle adjusting structure 100 of the present disclosure can effectively reduce the installation space by adjusting the angle of the elastic water injection member 120 through the adjusting assembly 110, so that the overall volume of the coffee maker 10 is reduced, and then the portability of the coffee maker 10 of the present disclosure is greatly improved.

[0060] 2. Compared with the improved structure of coffee machines in the above-mentioned related technologies, which uses a drive structure to move the entire water inlet pipe forward and backward relative to the machine body 300 to change the water inlet position, the water inlet angle adjustment structure 100 of this disclosure adjusts the angle of the elastic water inlet component 120 through the adjustment component 110, which can be adapted to more filter cups 600 of different shapes and sizes, thereby greatly improving the applicability of the coffee brewing machine 10 of this disclosure.

[0061] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
