[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] To provide a clearer explanation and description of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0038] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.

[0039] like Figure 1 , Figure 2 As shown, the present invention provides a needle-type coffee powder dispenser, including a support 10 and a handle 20 that can be moved up and down along the support 10. The lower end of the handle 20 is connected to a needle plate 30 through a lifting and rotating mechanism. Multiple powder needles 31 are provided on the bottom surface of the needle plate 30. When the needle-type coffee powder dispenser is placed on the coffee powder hopper, pressing the handle 20 can cause the needle plate 30 to move downward and rotate at the same time, stirring and compacting the coffee powder in the coffee powder hopper.

[0040] Combined Figure 3 As shown, the bracket 10 includes a ring 11, a bent arm 12 on the ring 11, and a handle sleeve 40 coaxially arranged with the ring 11 on the bent arm 12. Specifically, the bent arm 12 is provided with a threaded hole 13 coaxially arranged with the ring 11, and the handle sleeve 40 is threadedly connected to the threaded hole 13.

[0041] The shaft hole of the handle sleeve 40 is a stepped hole with a smaller upper part and a larger lower part. The inner wall of the lower part of the stepped hole is provided with a first internal thread. The handle 20 is slidably disposed in the stepped hole of the handle sleeve 40 and can move downward under pressure. The lower end of the handle sleeve 40 is provided with a one-way bearing 41 so that the needle plate 30 can only rotate in one direction. The needle plate 30 will not rotate when it is reset upward, thus improving the safety of use.

[0042] Combined Figures 1 to 7 As shown, the lifting and rotating mechanism includes a rotating shaft 50, a rotating shaft gear 60, and a double bevel gear 70.

[0043] A rotating shaft 50 is installed through a one-way bearing 41. The lower end of the rotating shaft 50 extends downward to connect to the needle plate 30, and the upper end of the rotating shaft 50 is provided with an internal threaded hole 51. The rotating shaft gear 60 includes a lead screw 61 and a rotating shaft bevel gear 62 disposed on the top surface of the lead screw 61. The lead screw 61 is disposed in the internal threaded hole 51 for meshing and fitting, so as to drive the rotating shaft 50 to move up and down.

[0044] The double bevel gear 70 is rotatably mounted at the lower end of the handle 20. The driving gear 71 of the double bevel gear 70 meshes with the first internal thread of the handle sleeve 40, and the driven gear 72 of the double bevel gear 70 meshes with the rotating shaft bevel gear 62.

[0045] In this embodiment, two double bevel gears 70 are provided. The two double bevel gears 70 are arranged opposite each other and rotate on both sides of the lower end of the handle 20, so that the handle sleeve 40 is subjected to uniform force and the handle 20 can move up and down flexibly.

[0046] A connecting rod 21 is coaxially mounted on the lower end face of the handle 20. The rotating shaft gear 60 has an axially penetrating connecting hole 63. The connecting rod 21 is inserted into the axial connecting hole 63 and rotates to engage. After the lower end of the connecting rod 21 passes through the rotating shaft gear 60, it is limited by a stop plate.

[0047] An annular flange 52 is provided on the upper end face of the rotating shaft 50, and a return spring 53 is provided between the annular flange 52 and the one-way bearing 41 to push the rotating shaft 50 upward to return to the initial position.

[0048] The lower end of the ring 11 is provided with a magnetic base 80, which is used to magnetically attach to the coffee powder container.

[0049] The upper end of the handle sleeve 40 is provided with an external thread, and the adjusting nut 90 is installed on the upper end of the handle sleeve 40 to adjust the up and down position of the handle sleeve 40, thereby adjusting the insertion depth of the powder needle 31.

[0050] In this utility model, the lower end of the handle sleeve 40 is provided with a lower end cover 42, and a one-way bearing 41 is provided on the top surface of the lower end cover 42. The lower end cover 42 is threadedly connected to the inner wall of the handle sleeve 40.

[0051] The working process of this utility model is as follows:

[0052] When the handle 20 is pressed down, it drives the two double bevel gears 70 and the rotating shaft gear 60 to move downward. At the same time, the first internal thread of the handle sleeve 40 drives the driving gear 71 to rotate, and the driven gear 72 drives the rotating shaft bevel gear 62 to rotate. The rotating shaft bevel gear 62 drives the rotating shaft gear 60 to rotate, and drives the rotating shaft 50 to rotate. Thus, the rotating shaft 50 drives the needle plate 30 to rotate, and the powder needle 31 on the needle plate 30 inserts into the coffee powder and stirs it evenly.

[0053] After the handle 20 is released, the spring force of the return spring 53 acts upward on the rotating shaft 50, causing the rotating shaft 50 to move upward and drive the handle to return to the initial position.

[0054] Based on the above description of specific embodiments, the needle-type coffee powder dispenser provided by this utility model has the following advantages compared with the prior art:

[0055] First, the lower end of the handle is connected to the needle plate via a lifting and rotating mechanism. Pressing the handle will lower and rotate the needle plate simultaneously, allowing for one-handed operation and making it convenient to use.

[0056] Secondly, the lifting and rotating mechanism includes a rotating shaft, a rotating shaft gear, and a double bevel gear. The rotating shaft is installed inside the handle sleeve, and the lower end of the rotating shaft is connected to the needle plate. The upper end of the rotating shaft has an inner hole, and the inner wall of the inner hole has a second internal thread. The double bevel gear is rotatably installed on both sides of the lower end of the handle. The driving gear of the double bevel gear meshes with the first internal thread of the handle sleeve, and the driven gear of the double bevel gear meshes with the rotating shaft bevel gear. Pressing the handle can make the needle plate descend and rotate at the same time. The structure is simple and the function is reliable.

[0057] Third, the lower end of the handle sleeve is equipped with a one-way bearing, and the shaft passes through the one-way bearing. Therefore, the needle plate can only be rotated when descending, and will not be rotated when resetting, making it safe to use.

[0058] Fourth, an adjusting nut is provided at the upper end of the portafilter sleeve to adjust the up-down position of the portafilter sleeve, thereby adjusting the degree of tamping of the coffee powder.

[0059] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0060] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
