Description

Technical Field

[0001] The invention relates to a device suitable for leveling coffee powder and a coffee bean grinder comprising the device. Background Art

[0002] Coffee is a popular beverage, and its production process plays a decisive role in the final taste and quality. Among them, leveling the ground coffee powder is an indispensable part of the coffee making process. The traditional method of leveling coffee powder is mainly to use a powder hammer to manually flatten it. However, since the distribution of coffee powder in the powder bowl may be uneven, after being flattened with a powder hammer, the coffee powder density in some places is high and in some places is low, resulting in uneven overall density of the powder cake. When brewing coffee, the coffee powder in the low-density area dissolves and penetrates too quickly, while the coffee powder in the high-density area dissolves too slowly, and the overall uniform dissolution cannot be achieved, thus affecting the taste of the coffee.

[0003] In order to solve the above technical problems, people began to try to use various devices to level the coffee powder. For example, a device for pressing ground coffee into a coffee filter basket disclosed in patent 202080060377.X, the device includes a filter basket for holding coffee powder, a shell, the shell includes a top and a bottom arranged horizontally up and down, and a main body connected therebetween, a positioning formation is provided on the main body of the shell, a vibrator is installed on the bottom of the shell, a bottom vibration platform is installed on the vibrator, and the bottom vibration platform is operatively connected to the vibrator. When the filter basket base is placed on the bottom vibration platform and positioned on the positioning formation, the vibrator is started, and the vibration platform directly transmits the vibration generated by the vibrator to the filter basket and the coffee powder in the basket, promoting the fluidization or partial fluidization of the coffee powder in the filter basket to help disperse and reduce accumulation, thereby promoting the uniform distribution of coffee powder in the basket. Summary of the invention

[0004] After an in-depth analysis of the device for pressing ground coffee into the coffee filter basket in Patent 202080060377.X, it was found that its design had significant defects. For example, since the vibrator was directly installed at the bottom of the housing, the vibration energy generated by the vibrator was not only transmitted to the filter basket, but also widely dispersed to other parts of the housing and other components connected thereto. This not only caused unnecessary waste of energy, but also caused significant noise problems, greatly reducing the user experience.

[0005] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a device suitable for leveling coffee powder, which can improve the utilization rate of vibration energy and effectively reduce the noise generated by vibration during the leveling of coffee powder.

[0007] According to the technical solution proposed in the present invention, compared with the prior art, the beneficial technical effect of the present invention is that: since one end of the transmission member is connected to the load-bearing part, and the other end is a free end and is suspended in the air, this is conducive to increasing the vibration energy transmitted to the load-bearing part, reducing the vibration energy dispersed to other components, optimizing the effective utilization rate of the vibration energy, and helping to reduce the noise generated during the vibration transmission process.

[0010] A further technical solution may be that the transmission member includes a first transmission part and a second transmission part which are separately arranged and connected together, the first transmission part is connected to the loading part, and the vibrator is installed on the second transmission part.

[0011] A further technical solution may be that the loading part includes a back plate and a supporting base frame for supporting the coffee powder container, the back plate is fixed to the base by screws, and the supporting base frame and the transmission member are respectively connected to the lower plate body on the back plate located below the screws.

[0012] A further technical solution may also be that a window portion is provided on the base, the lower plate body of the back plate is located in front of the base and covers at least part of the window portion, the supporting base is connected to the front side wall of the lower plate body of the back plate, the transmission member passes through the window portion and is connected to the rear side wall of the lower plate body of the back plate, and a buffer pad is provided between the lower plate body of the back plate and the outer peripheral wall of the window portion.

DETAILED DESCRIPTION

[0018] The following is a further description of the device for leveling coffee powder and the coffee bean grinder according to the technical solution of the present invention in conjunction with the accompanying drawings.

[0019] like Figures 1 to 5 As shown, a bean grinder comprises a device for leveling coffee powder and a bean grinding module for supplying coffee powder to the coffee powder container 9, wherein the bean grinding module is mounted on the base 1, and comprises a bean bin 7 for storing coffee beans and a grinder 71 for grinding the coffee beans in the bean bin 7 into coffee powder. The device for leveling coffee powder is characterized by comprising: a base 1; a loading portion 2, positioned on the base 1, and used to place the coffee powder container 9; a transmission member 3, one end of the transmission member 3 is connected to the loading portion 2, and the other end is a free end and is suspended; a vibrator 4, used to vibrate the free end of the transmission member 3, and the transmission member 3 transmits the vibration to the coffee powder container 9 to level the coffee powder stored in the coffee powder container 9; and a controller (not shown in the figure), used to be connected to the vibrator 4 by signal, and control the operation of the vibrator 4 according to the received instructions.

[0020] The base 1 is a basic part for positioning the loading part 2. In addition, the base 1 can also provide positioning for other functional parts. The base 1 can be a one-piece component with a single integral structure, or a combination of multiple discrete parts assembled and integrated. For example, in the present embodiment, the base 1 is the outer shell of the bean grinder, and the bean grinding module, the powder outlet channel 8 for receiving the coffee powder ground by the bean grinding module, and the control handle 9 for inputting vibration instructions to the controller are also installed on the base 1. Under the action of the controller, the working parameters of the vibrator 4, such as the start time (for example, during the grinding process or after the grinding process) and the working time and other working parameters can be flexibly adjusted, so as to regulate the flatness of the coffee powder stored in the coffee powder container 9.

[0021] There are various ways to position the loading part 2 on the base 1, such as locking it on the base 1 by a locking screw; or the base 1 includes an outer shell and a fixing platform installed on the outer shell, and the loading part 2 is connected to the fixing platform.

[0022] The transmission member 3 is a power transmission member for transmitting vibrations, which can be an integrated component of a single integral structure, or a combination formed by assembling and integrating a plurality of discrete separate components. For example, in the present embodiment, the transmission member 3 includes a first transmission part 31 and a second transmission part 32 which are separately arranged and connected together, wherein the first transmission part 31 is connected to the object-carrying part 2, and the vibrator 4 is installed on the second transmission part 32. The first transmission part 31 and the object-carrying part 2 can be an integrated structure or a separate structure and connected together. In addition, one end of the transmission member 3 is connected to the object-carrying part 2, and the other end is a free end and is suspended. This is conducive to increasing the vibration energy transmitted to the object-carrying part 2, reducing the vibration energy dispersed to other components, optimizing the effective utilization rate of the vibration energy, and helping to reduce the noise generated during the vibration transmission process.

[0023] Among them, the structural form of the vibrator 4 is diverse, and specific reference can be made to the structure disclosed in the existing patent 202080060377.X. The vibrator 4 can be installed on the substrate 1 or other components on the substrate 1, and in order to further improve the utilization rate of vibration energy and reduce the noise generated during vibration transmission, further, the vibrator 4 is installed on the free end of the transmission member 3, and is suspended in the air by means of the suspended setting of the free end of the transmission member 3. The vibrator 4 includes a drive motor 41 and a cam 42 installed on the output shaft of the drive motor 41, and the drive motor 41 is connected to the controller signal; it also includes a pressure strip 5 installed on the free end of the transmission member 3, and the drive motor 41 is clamped between the free end of the transmission member 3 and the pressure strip 5. When the drive motor 41 drives the cam 42 to rotate, the cam 42 knocks the free end of the transmission member 3 or the pressure strip 5 to vibrate the free end of the transmission member 3.

[0024] In order to further reduce noise, the base 1 includes a receiving cavity 10, the object-carrying portion 2 is located outside the receiving cavity 10, and the free end of the transmission member 3 and the vibrator 4 are located inside the receiving cavity 10. In this way, the receiving cavity 10 is used to effectively block and reduce the noise generated by the free end of the transmission member 3 and the vibrator 4 when vibrating from propagating outward.

[0025] Two structural forms of the object carrier 2 are proposed below, which can be used independently or in combination in the same embodiment.

[0026] The first structural form of the load-carrying part 2: The load-carrying part 2 includes a back plate 21 and a supporting frame 22 for supporting the coffee powder container 9. The back plate 21 is fixed to the base 1 by screws, and the supporting frame 22 and the transmission member 3 are respectively connected to the lower plate 210 located below the screws on the back plate 21. In this way, the lower plate 210 of the back plate 21 is not fixed to the base 1, and the lower plate 210 of the back plate 21 has a relatively large degree of freedom compared to the part of the plate locked by the screws. When the transmission member 3 transmits vibration to the lower plate 210 of the back plate 21, the lower plate 210 of the back plate 21 can vibrate relatively greatly with the supporting frame 22, which helps to further improve the effective utilization rate of vibration energy.

[0027] Furthermore, the base 1 is provided with a window portion 11, the lower plate 210 of the back plate 21 is located in front of the base 1 and blocks at least part of the window portion 11, the supporting chassis 22 is connected to the front side wall of the lower plate 210 of the back plate 21, the transmission member 3 passes through the window portion 11 and is connected to the rear side wall of the lower plate 210 of the back plate 21, and a buffer pad (not shown in the figure) is provided between the lower plate 210 of the back plate 21 and the outer peripheral wall of the window portion 11. The lower plate 210 of the back plate 21 blocks at least part of the window portion 11, which can be understood as the lower plate 210 of the back plate 21 blocks part or all of the window portion 11. The front side wall and the rear side wall of the lower plate 210 of the back plate 21 are the side walls on two opposite directions on the lower plate 210 of the back plate 21. If the side wall on one direction is defined as the front side wall, the side wall opposite to it is the rear side wall. The supporting frame 22 and the transmission member 3 are respectively placed on the front and rear sides of the lower plate 210 of the back plate 21. Since the weight of the coffee powder container 9 is generally large, when the coffee powder container 9 is placed on the supporting frame 22, the back plate 21 can lean against the base 1 to obtain support and reduce the degree of deformation. In addition, the noise generated by the lower plate 210 of the back plate 21 hitting the outer peripheral wall of the window part 11 during vibration can be reduced by means of the buffer pad. Of course, a buffer pad can also be provided between the upper plate above the screw on the back plate 21 and the outer peripheral wall of the window part 11.

[0028] The second structural form of the load-carrying part 2: the load-carrying part 2 includes a back plate 21 and a supporting frame 22 for supporting the coffee powder container 9, the back plate 21 is connected to the base 1, the inner end of the supporting frame 22 close to the back plate 21 is connected to the back plate 21, and the outer end of the supporting frame 22 away from the back plate 21 is suspended. In this way, the supporting frame 22 is conducive to increasing the vibration energy transmitted to the coffee powder container 9 during the vibration transmission process, reducing the vibration energy dispersed to other components, optimizing the effective utilization rate of the vibration energy, and helping to reduce the noise generated during the vibration transmission process.

[0029] Furthermore, the loading part 2 also includes an upper frame 24 located above the supporting base 22, and a loading space for placing the coffee powder container 9 is formed between the upper frame 24 and the supporting base 22. The upper frame 24 can be raised and lowered relative to the supporting base 22 to adjust the height of the loading space.

[0030] Furthermore, a support column 23 is provided on the supporting base frame 22, and the upper frame 24 is slidably provided on the support column 23; an adjustment hole 240 is provided on the upper frame 24, and a bolt 25 can pass through the adjustment hole 240 and press on the support column 23 to fix the height of the upper frame 24. In this way, after loosening the bolt 25, the position of the upper frame 24 on the support column 23 can be adjusted, and after adjustment, tightening the bolt 25 can fix the height of the upper frame 24.
