DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 to Figure 5 The embodiment of the utility model provides a powder grinding device for preventing flying powder for a coffee machine, comprising: a bottom plate 1, the lower surface of the bottom plate 1 is evenly provided with bottom feet 2, and the outer wall of the bottom plate 1 is provided with a suction port 3, the inner cavity of the bottom plate 1 is hollow, and the suction port 3 is connected to and communicates with the inner cavity of the bottom plate 1;

[0024] Specifically, the interior of the chassis 1 is hollow, in which ground coffee powder can be stored, thereby collecting and preserving the coffee powder. The coffee powder in the chassis 1 can be extracted by utilizing the suction port 3 connected to the inner cavity of the chassis 1, thereby avoiding the problem of flying powder when extracting the coffee powder.

[0025] Lifting bases 4 are fixedly arranged on both sides of the chassis 1, and electric lifting rods 5 extend from the top of the lifting bases 4. The electric lifting rods 5 are arranged in the lifting bases 4 at equal distances, and the top end surfaces of the electric lifting rods 5 are movably embedded with balls 6;

[0026] Specifically, the electric lifting rod 5 is used to support the grinding disc 10 to keep the grinding disc 10 in a balanced state. The design of the ball 6 is to ensure that the grinding disc 10 can rotate smoothly when the grinding disc 10 rotates to grind the coffee beans.

[0027] A rubber airbag 7 is provided on one side of the electric lifting rod 5 close to the vertical center line of the chassis 1, and the bottom of the rubber airbag 7 is fixedly connected to the upper surface of the chassis 1, the upper edge of the rubber airbag 7 is in an arc shape, and the upper edge surface of the rubber airbag 7 is consistent with the inner groove structure of the lower surface of the grinding disc 10;

[0028] Specifically, the rubber airbag 7 is used to form a sealed space between the chassis 1 and the grinding disc 10 when grinding coffee beans. After the grinding disc 10 descends, the gap between it and the chassis 1 continues to narrow. At the same time, the grinding disc 10 continues to rotate, so that the coffee beans placed between the chassis 1 and the grinding disc 10 can be ground under the action of friction. As the grinding disc 10 descends, the rubber airbag 7 is gradually compressed, and the chassis 1 and the grinding disc 10 are always surrounded by the rubber airbag 7. The coffee powder ground therein will not fly out and can be completely collected.

[0029] A powder filter net 8 is provided on the rubber airbag 7 near the side of the vertical center line of the chassis 1 and inside the upper surface of the chassis 1. A grinding table 9 is fixedly connected to the powder filter net 8 near the side of the vertical center line of the chassis 1 and at the center of the upper surface of the chassis 1. The grinding table 9 is a truncated cone structure. The powder filter net 8 is connected to the inner cavity of the chassis 1.

[0030] Specifically, the powder filter 8 is used to filter the coffee powder to ensure the fineness and quality of the coffee powder. The coffee powder is screened by the powder filter 8 and enters the inner cavity of the chassis 1 to be collected and preserved. The surface of the grinding table 9 is rough. After contacting with the grinding disc 10, it will produce a high degree of friction, and then grind the coffee beans placed therein. The ground coffee powder will naturally fall along the inclined surface of the grinding table 9 to the powder filter 8, and enter the inner cavity of the chassis 1 after being filtered through the sieve of the powder filter 8.

[0031] A grinding disc 10 is installed above the electric lifting rod 5, and an upper support plate 11 is arranged above the grinding disc 10. A rotating shaft 12 is fixed to the center of the upper surface of the grinding disc 10, and the rotating shaft 12 passes through the center of the upper support plate 11. A motor 13 is connected to the upper end of the rotating shaft 12. Connecting plates 14 are connected below both ends of the upper support plate 11, and lower support plates 15 are connected below the connecting plates 14. A lifting structure is formed between the upper support plate 11 and the lower support plate 15 through the connecting plate 14, and a hydraulic cylinder 16 is installed on the inner side of the lower support plate 15. A hydraulic telescopic rod 17 is connected to the upper connecting end of the hydraulic cylinder 16, and the top end of the hydraulic telescopic rod 17 is connected to the inner top surface of the upper support plate 11;

[0032] Specifically, the grinding disc 10 is driven to rotate by the motor 13 to complete the grinding work. The upper support plate 11 can be raised and lowered on the basis of the lower support plate 15 using the connecting plate 14, so that the grinding disc 10 can be moved up and down. When the grinding disc 10 moves up, coffee beans can be placed on the grinding table 9. The grinding disc 10 moves down until the rubber airbag 7 cuts into the inner groove structure on the lower surface of the grinding disc 10, and then the grinding work can be started. The up and down movement of the upper support plate 11 depends entirely on the hydraulic extension and contraction control of the hydraulic telescopic rod 17 by the hydraulic cylinder 16. When the hydraulic telescopic rod 17 is extended, the upper support plate 11 moves up, and vice versa. The upper support plate 11 drops.

[0033] The working principle of the utility model is:

[0034] Start the hydraulic cylinder 16, and turn on the internal control switch of the lifting base 4 accordingly, so that each electric lifting rod 5 is energized, and the hydraulic telescopic rod 17 is extended by hydraulic control, and each electric lifting rod 5 is extended synchronously, and the hydraulic telescopic rod 17 raises the upper support plate 11, and then moves the grinding disc 10 upward. The left and right sides of the grinding disc 10 are stably supported by the electric lifting rod 5. At this time, the grinding disc 10 is separated from the chassis 1, and coffee beans are placed on the grinding table 9. Then the hydraulic telescopic rod 17 and each electric lifting rod 5 are controlled to shrink synchronously, and the grinding disc 10 descends until the rubber airbag 7 cuts into the inner groove structure on the lower surface of the grinding disc 10, and then the motor 13 can be turned on, and the rotating shaft 12 immediately drives the grinding disc 10 to rotate to grind the coffee beans on the grinding table 9. The grinding disc 10 rotates and descends at the same time, and the coffee beans on the grinding table 9 are ground finer and finer. The obtained coffee powder will naturally slide along the inclined outer wall of the grinding table 9 to the position of the powder filter 8, and will be finely sieved by the powder filter 8 and enter the inner cavity of the chassis 1. When taking it out, it can be extracted from the suction port 3.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
