[0027] In order to further understand the content, characteristics and effects of the present utility model, the following embodiments are cited and described in detail with the accompanying drawings as follows

[0028] Such as Figures 1 to 6As shown in the figure, an automatic powder pressing device of the present utility model includes: a housing 1, on which a base 2 and a bracket 4 for supporting a funnel 3 are provided, and the bracket 4 is located below the base 2; a motor 5, which is fixed on the base 2, and a driving gear 52 is fixed on the rotating shaft 51 of the motor 5, and a driven gear 53 meshing with the driving gear 52 is also provided on one side of the driving gear 52; a lifting frame 6, which is slidably arranged on the base 2, and a powder pressing head 8 that can extend into the bracket 4 and contact the funnel 7 supported on the bracket 4 is provided at the lower end of the lifting frame 6. The lifting frame 6 is provided with a first rack 61 and a second rack 62. The first rack 61 meshes with the driving gear 52, and the second rack 62 meshes with the driven gear 52. Compared with the prior art, the automatic powder pressing device of the present utility model is composed of a motor 5, a driving gear 52, a driven gear 53 and a lifting frame 6. When the motor 5 is powered on and rotates forward, the rotating shaft 51 of the motor 5 drives the driving gear 52 to rotate forward. The rotation of the driving gear 52 synchronously drives the driven gear 53 and the first rack 61 of the lifting frame 6. The reverse rotation of the driven gear 53 also synchronously drives the second rack 62 of the lifting frame 6, so that the lifting frame 6 moves downward and extends into the bracket 4, and the powder pressing head 8 contacts the funnel 3 supported on the bracket 4 to press the coffee powder in the funnel 3. After the pressing is completed, the motor 5 rotates reversely. The rotating shaft 51 of the motor 5 drives the driving gear 52 to rotate reversely. The reverse rotation of the driving gear 52 synchronously drives the driven gear 53 and the first rack 61 of the lifting frame 6. The forward rotation of the driven gear 53 also synchronously drives the second rack 62 of the lifting frame 6, so that the lifting frame 6 moves upward and leaves the funnel 3 and the bracket 4, thus realizing automatic powder pressing, and having the advantages of simple structure, convenient use and good user experience.

[0029] Furthermore, the housing 1 is also provided with a cover 9, which covers the base 2. A first guide groove 21 is provided on each side of the base 2, and a first guide rail 67 that can be embedded in the first guide groove 21 is correspondingly provided on each side of the lifting frame 6. Second guide grooves 91 are provided on both sides of the cover 9, and a second guide rail 68 that can be embedded in the second guide grooves 91 is correspondingly provided on both sides of the lifting frame 6.

[0030] Optionally, sleeves 10 are provided on both the cover 9 and the base 2. Both ends of the driven gear 53 are pivotally connected in the sleeves 10 of the cover 9 and the base 2, and the other end of the driving gear 52 is also pivotally connected in another sleeve 10 of the cover 9.

[0031] Specifically, the lifting frame 6 is provided with an inner cavity 63, and the first rack 61 and the second rack 62 are respectively arranged on both sides of the inner cavity 63. The first rack 61 and the second rack 62 are respectively arranged on both sides of the inner cavity 63 and cooperate with the driving gear 52 and the driven gear 53, which has the advantages of smooth and stable lifting of the lifting frame 6. A through hole 64 is also provided at the lower end of the lifting frame 6, and a sliding column 65 that can slide relative to the through hole is arranged in the through hole 64. One end of the sliding column 65 is connected to the lifting frame 6, and the other end is fixedly connected to the powder pressing head 8. A spring 66 is sleeved on the sliding column 65. One end of the spring 66 elastically presses on the lower end of the lifting frame 6, and the other end of the spring 66 elastically presses on the powder pressing head 8.

[0032] Wherein, a first microswitch 92 and a second microswitch 93 are fixed on the outer side of the cover body 9. A through groove 94 is also provided on the cover body 9. A trigger block 69 that extends out of the cover body 9 through the through groove 94 and can trigger the first microswitch 92 or the second microswitch 93 is arranged on one of the second guide rails 68 of the lifting frame 6. The first microswitch 92 is located above the second microswitch 93. When the lifting frame 6 is in the initial position, the trigger block 69 presses the first microswitch 92, and the first microswitch 92 is in the closed state. When the motor 5 is powered on, it rotates to drive the lifting frame 6 to move downward. After the lifting frame 6 moves downward, the trigger block 69 no longer presses the first microswitch 92, and the first microswitch 92 changes from the closed state to the open state; when the lifting frame 6 moves downward to the point where the trigger block 69 presses the second microswitch 93 and the second microswitch 93 changes from the open state to the closed state, the motor 5 stops working. The movement of the lifting frame 6 is only to transport the powder pressing head 8 to the funnel 7, and then the elastic force formed by the compression of the spring 66 acts on the powder pressing head 8 for powder pressing. When the lifting frame 6 moves to the set position where the trigger block 69 presses the second microswitch 93 after moving downward, the motor 5 stops working and the powder pressing also stops. The more coffee there is in the funnel 7, the greater the compression amount of the spring 66, and thus the greater the powder pressing force. When the lifting frame 6 moves upward and returns, before the spring 66 returns to its original state, its elastic force always acts on the powder pressing head 8, and the powder pressing head 8 will always press on the coffee powder surface in the funnel 7, which has the advantages of effectively prolonging the powder pressing time and more sufficient powder pressing.

[0033] As Figure 7 shown, the present invention also provides a coffee machine. A brewer 11 for brewing the coffee powder in the funnel 3 is provided on one side of the coffee machine, and an automatic powder pressing device as described above is provided on the other side of the coffee machine. Compared with the prior art, the coffee machine of the present invention integrates the automatic powder pressing device onto the coffee machine. In addition to having the advantages of the aforementioned automatic powder pressing device, it also has the advantages of making the coffee machine structure compact and increasing the added value of the product.

[0034] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
