[0032] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0033] First, as Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model provides a powder sealing structure, including a machine body 1, a fixed plate 2, a movable plate 3, a gear 4 and a driving member 5. The machine body 1 has a powder outlet 11 and a water outlet 12, and the water outlet 12 is located on one side of the powder outlet 11. The fixed plate 2 is fixedly arranged on the machine body 1, and there is a gap between the fixed plate 2 and the machine body 1. The movable plate 3 is slidably arranged in the gap, and a first elongated hole 31 is provided on the movable plate 3, and the side wall of the first elongated hole 31 has a plurality of convex teeth 311. The gear 4 is arranged in the first elongated hole 31 and meshes with the plurality of convex teeth 311. The driving member 5 is arranged on the machine body 1, and one end of the driving member 5 is connected to the gear 4.

[0034] In a specific application, when the coffee powder ground by the bean grinding device falls into the hand brewing pot through the powder outlet 11, the gear 4 is driven to rotate by the driving member 5, and the gear 4 cooperates with the plurality of convex teeth 311, so that the movable plate 3 moves to correspond to the powder outlet 11, thereby sealing the powder outlet 11, thereby preventing water vapor from entering the bean grinding device through the powder outlet 11, causing the ground coffee powder in the bean grinding device to condense into lumps and block the powder outlet 11.

[0035] Specifically, the driving member 5 may be a push rod. When the driving member 5 is a push rod, it is necessary to manually push the push rod to drive the movable plate 3 to move, so as to realize the opening and closing of the powder sealing structure. Preferably, the driving member 5 is a motor. When the driving member 5 is a motor, the motor is electrically connected to the control system of the coffee machine, and the control system can control the motor to realize the automatic opening and closing of the powder sealing structure, which is more convenient to use.

[0036] It should be noted that the plurality of protruding teeth 311 disposed on the side wall of the first elongated hole 31 are arranged along the length direction of the first elongated hole 31 .

[0037] like Figure 3 As shown, in some preferred embodiments, the above-mentioned moving plate 3 is provided with a second elongated hole 32, the second elongated hole 32 is parallel to the first elongated hole 31, and the machine body 1 is provided with a guide column 13, one end of the guide column 13 extends into the second elongated hole 32. In specific applications, the movement accuracy of the moving plate 3 can be improved by cooperating with the second elongated hole 32 and the guide column 13, so that the moving plate 3 can accurately block the powder outlet 11 to ensure a good blocking effect.

[0038] like Figure 4 and Figure 5As shown, in some preferred embodiments, the powder sealing structure further includes a powder guide tube 6, one end of which is arranged on the machine body 1 and corresponds to the powder outlet 11. In a specific application, the powder outlet of the bean grinding device is connected to the other end of the powder guide tube 6. By arranging the powder guide tube 6 on the machine body 1, the coffee powder in the bean grinding device passes through the powder outlet of the bean grinding device, the powder guide tube 6 and the powder outlet 11 in sequence and directly falls into the hand brewing pot.

[0039] like Figure 5 As shown, in some preferred embodiments, the end surface of one end of the powder guide tube 6 is provided with a first mounting groove 61, a first sealing ring 7 is provided in the first mounting groove 61, and the movable plate 3 is movably in contact with the first sealing ring 7. In specific applications, the first sealing ring 7 cooperates with the movable plate 3 to prevent water vapor from entering the bean grinding device through the gap between the movable plate 3 and the powder outlet 11 or between the powder guide tube 6 and the powder outlet 11, further improving the blocking effect.

[0040] like Figure 5 As shown, in some preferred embodiments, one end of the powder guide tube 6 extends into the powder outlet 11. In specific applications, by designing one end of the powder guide tube 6 to extend into the powder outlet 11, it is not only easy to install the powder guide tube 6, but also more secure after installation.

[0041] like Figure 5 As shown, in some preferred embodiments, the outer wall of one end of the powder guide tube 6 is provided with a second mounting groove 62, and a second sealing ring 8 is provided in the second mounting groove 62, and the second sealing ring 8 abuts against the side wall of the powder outlet 11. By providing the second sealing ring 8 on the outer wall of one end of the powder guide tube 6, the second sealing ring 8 can seal the gap between the powder guide tube 6 and the powder outlet 11, thereby preventing water vapor from entering the bean grinding device through the gap between the powder guide tube 6 and the powder outlet 11.

[0042] like Figure 3 As shown, in some preferred embodiments, the body 1 has a groove 14 that matches the shape of the moving plate 3, and the moving plate 3 is disposed in the groove 14 and can move in the groove 14. By providing the groove 14 that matches the shape of the moving plate 3 on the body 1, the groove 14 can guide the moving plate 3 to ensure the moving accuracy of the moving plate 3.

[0043] like Figure 2 , Figure 3 and Figure 5As shown, in some preferred embodiments, the above-mentioned fixed plate 2 is arranged in the groove 14, and the sum of the thickness of the fixed plate 2 and the thickness of the movable plate 3 is less than or equal to the depth of the groove 14. In a specific application, by arranging the fixed plate 2 in the groove 14, and designing the sum of the thickness of the fixed plate 2 and the thickness of the movable plate 3 to be less than or equal to the depth of the groove 14, the fixed plate 2 will not protrude from the body 1, thereby preventing the fixed plate 2 from scratching the hands when taking and putting the hand-infused kettle.

[0044] In a second aspect, the utility model provides a coffee machine, comprising the powder sealing structure of the first aspect, a water tank, a water pump, a heating element, a bean grinding device and a hand brewing pot.

[0045] In specific applications, when coffee needs to be made, first, the powder sealing structure is opened so that the movable plate 3 and the powder outlet 11 are in a misaligned state (that is, the movable plate 3 and the powder outlet 11 do not correspond), and the bean grinding device grinds the coffee beans into coffee powder, which falls into the filter of the hand brewing pot through the powder discharge port of the bean grinding device, the powder guide tube 6 and the powder outlet 11 in turn; secondly, the gear 4 is driven to rotate by the driving member 5 to drive the movable plate 3 to seal the powder outlet 11 (that is, the movable plate 3 and the powder outlet 11 correspond); finally, the cold water in the water tank is pumped into the heating element through the water pump for heating, and the heated hot water is injected into the hand brewing pot through the water outlet 12 to mix with the coffee powder to form hot coffee.

[0046] To sum up, in one or more embodiments of the present invention, the powder sealing structure and the coffee machine of the present invention drive the gear to rotate through the driving member, thereby driving the movable plate to move through multiple convex teeth, so that the movable plate can seal the powder outlet when the powder outlet is not in use, thereby preventing the ground coffee powder in the grinding device from condensing into lumps due to the influence of water vapor and blocking the powder outlet, thereby ensuring the normal use of the coffee machine.
