Technical Field
[0001] This utility model relates to the field of coffee processing equipment technology, and more specifically, to a coffee powder feeding device for a coffee machine. Background Technology
[0002] The existing coffee machine has a coffee grinder installed on one side. When the coffee grinder is working, coffee beans are first put into the grinding inlet at the top, the drum is closed, and then the output is set. After the operator attaches the receiving rings of different heights above the receiving scoop, the receiving scoop is placed on the support below the outlet of the coffee grinder to start the feeding operation. After feeding, the coffee powder piled inside the receiving scoop needs to be shaken to mix it. Then, it is compacted by the tamper, the receiving rings are removed, and the receiving scoop full of compacted coffee powder is connected to the liquid outlet at the bottom of the coffee machine. The finished coffee is brewed by spraying high-pressure, high-temperature liquid.
[0003] The existing coffee grinders have the following problems with their feeding area: First, the support below the discharge port is a fixed structure and cannot be adjusted in height. When a large or small amount of coffee powder needs to be loaded at once, a receiving ring of a higher or lower height needs to be used accordingly. Some of the higher receiving rings cannot be inserted into the support below the discharge port, while the lower receiving rings are too far from the discharge port, causing the coffee powder to easily overflow and be wasted during the fall, making them not very versatile. Second, after feeding, the operator still needs to manually shake the grinder to even out the coffee powder inside the receiving scoop, which is cumbersome and affects the efficiency of coffee making. Utility Model Content
[0004] The purpose of this invention is to provide a coffee powder feeding device for a coffee machine. This device features an adjustable support structure to accommodate powder receiving rings of different heights, and it can also shake the coffee powder inside the feeding scoop to mix it, thereby improving the applicability of the feeding device and the efficiency of coffee making.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A coffee powder feeding device for a coffee machine includes a coffee powder grinder. A base plate is installed at the lower end of the grinder, and a power supply line is connected to the rear end. A discharge port is located at the front of the grinder body. A grinding disc assembly is installed at the upper end of the grinder. The outer periphery of the upper surface of the grinding disc assembly is machined with scale lines, and a pointer is fitted at the center of the grinding disc assembly. A drum is fitted onto the feed inlet above the grinding disc assembly. A receiving scoop is placed below the discharge port, and a powder-receiving ring is embedded in the scoop's opening area. The lugs on both sides of the receiving scoop are inserted forward into the hollow area between the upper and lower plates of a lifting bracket. The rear ends of the lifting bracket are slidably fitted onto two vertically parallel guide rods through through-holes on both sides. Tightening bolts are screwed into the rear side of the lifting bracket, and these bolts are tightened inward onto the guide rods to limit the height of the lifting bracket. Anti-slip washers are installed on the outer ends of both the upper and lower plates of the lifting bracket. A circular baffle is installed on the top of the guide rods.
[0007] As a further optimization of this solution, the lower ends of the two vertically parallel guide rods are both installed on the upper surface of the vibrating plate. The vibrating plate is embedded in the bottom plate surface with a groove inside, and the bottom plate surface above the front and rear ends of the vibrating plate is equipped with limit stops by bolts. A vibration motor with a polarizing block is installed at the center of the upper surface of the vibrating plate.
[0008] As a further optimization of this solution, the front and rear ends of the left and right sides of the vibration plate and the front and rear ends of the left and right inner sides of the groove are all equipped with protrusions, and a return spring is provided between the aligned protrusions.
[0009] As a further optimization of this solution, a protective shell with an opening at the top is installed on the upper surface of the bottom plate surrounding the limiting stop bar.
[0010] As a further optimization of this solution, a control button is provided on the upper surface of the base plate. The control button is connected to the vibration motor via a circuit. The vibration motor shares a power supply with the grinding disc assembly.
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0012] This invention incorporates two vertically parallel guide rods and a lifting bracket structure. The height of the lifting bracket can be adjusted according to the height of the powder receiving ring used, and limited by locking bolts. When a higher powder receiving ring is required, the height of the lifting bracket can be lowered to allow the powder receiving ring opening to smoothly enter the position below the outlet. When a lower powder receiving ring is required, the height of the lifting bracket can be raised to align the powder receiving ring opening with the position below the outlet, thus avoiding coffee powder overflow and waste caused by the distance from the outlet.
[0013] In this invention, a vibrating motor drives a vibrating plate to vibrate left and right inside the groove along the limiting direction of the limiting strip. This causes the coffee powder inside the receiving scoop and the powder receiving ring to shake left and right, replacing the traditional manual shaking by workers. This shakes the coffee powder inside the receiving scoop evenly, improving coffee making efficiency. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0019] To address the issue that existing coffee grinders have a fixed support structure below the outlet, which cannot be adjusted in height, and that when a higher or lower powder receiving ring is needed, the higher powder receiving ring cannot be inserted into the support below the outlet for feeding, while the lower powder receiving ring is too far from the outlet, causing coffee powder to easily overflow and be wasted, resulting in poor applicability;
[0020] like Figure 1 As shown, this application includes a coffee grinder 1, a base plate 2 installed at the lower end of the coffee grinder 1 and a power supply line 3 connected to the rear end of the coffee grinder 1, a discharge port 4 at the front of the coffee grinder 1, a grinding disc assembly 5 installed at the upper end of the coffee grinder 1, scale lines 6 machined on the outer periphery of the upper surface of the grinding disc assembly 5 and a pointer 7 fitted at the center of the grinding disc assembly 5, a drum cylinder 8 fitted on the feed port above the grinding disc assembly 5, a receiving spoon 9 placed below the discharge port 4 and a powder receiving ring 10 embedded in the spoon area of the receiving spoon 9;
[0021] like Figure 2As shown, the hanging ears on both sides of the receiving spoon 9 are inserted forward into the hollow area between the upper and lower clamping plates of the lifting bracket 12. The two rear sides of the lifting bracket 12 are slidably fitted into the two vertical parallel guide rods 11 through the through holes. The tightening bolts 14 are screwed into the rear side of the lifting bracket 12. The tightening bolts 14 are tightened inward on the guide rods 11 to limit the height of the lifting bracket 12. Anti-slip washers are installed on the outer ends of the upper and lower clamping plates of the lifting bracket 12. A circular baffle 13 is installed on the top of the guide rods 11.
[0022] Specifically, the height of the lifting bracket 12 can be adjusted according to the height of the powder receiving ring 10 used, and limited by the locking bolt 14. When a higher powder receiving ring 10 is needed, the height of the lifting bracket 12 can be adjusted downward to lower the height so that the opening of the powder receiving ring 10 can smoothly enter the position below the outlet 4. When a lower powder receiving ring 10 is needed, the height of the lifting bracket 12 can be adjusted upward to raise the height so that the opening of the powder receiving ring 10 is aligned with the position below the outlet 4, avoiding the phenomenon of coffee powder overflow and waste caused by being too far from the outlet 4.
[0023] To address the issue that after the existing coffee grinder has finished feeding the coffee powder, the staff still needs to manually shake the machine to even out the coffee powder inside the receiving scoop, which is a cumbersome operation and affects the efficiency of coffee making;
[0024] like Figure 3 As shown, the lower ends of two vertically parallel guide rods 11 are both installed on the upper surface of the vibrating plate 17. The vibrating plate 17 is embedded in the groove 16 on the surface of the base plate 2. Limiting strips 19 are installed on the surface of the base plate 2 above the front and rear ends of the vibrating plate 17 by bolts. A vibration motor 18 with a polarizing block is installed at the center of the upper surface of the vibrating plate 17. The front and rear ends of the left and right sides of the vibrating plate 17 and the front and rear ends of the left and right inner sides of the groove 16 are all aligned and installed with protrusions 20. A return spring 21 is provided between the aligned protrusions 20. A protective shell 15 with an upper opening is installed on the upper surface of the base plate 2 around the limiting strips 19.
[0025] Specifically, the upper surface of the base plate 2 is equipped with a control button 22, which is connected to the vibration motor 18 via a circuit. The vibration motor 18 shares a power supply with the grinding disc assembly 5. After the operator fills the receiving scoop 9 and the powder receiving ring 10 with coffee powder, they can press the control button 22 to start the vibration motor 18 to rotate, which drives the polarization block to rotate and drives the vibration plate 17 to vibrate left and right in the groove 16 along the limiting direction of the limiting strip 19. This causes the coffee powder inside the receiving scoop 9 and the powder receiving ring 10 to shake left and right, replacing the traditional manual shaking by the operator. This shakes the coffee powder inside the receiving scoop 9 evenly, improving the coffee making efficiency. After the shaking is completed, the operator can press the control button 22 to turn off the vibration motor 18. The vibration plate 17 returns to its original position under the action of the return spring 21. The operator can then directly pull out the receiving scoop 9 from the hollow area between the upper and lower clamping plates of the lifting bracket 12 to proceed with the subsequent coffee making process.
