[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with its embodiments. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0039] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0040] On the one hand, if Figure 1 and Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a powder blocking structure in one embodiment of the utility model is arranged in a mounting housing, and includes:

[0041] The powder outlet housing 1 is provided with a powder outlet 101;

[0042] The baffle 2 is arranged below the powder outlet 101 and comprises a rotating portion 21, a limiting portion 22, and a material blocking portion 23 arranged between the rotating portion 21 and the limiting portion 22;

[0043] The limiting plate 3 is arranged below the powder outlet 101 and forms an accommodation space for accommodating the limiting portion 22 together with the powder outlet housing 1;

[0044] The driving component 4 is disposed on the powder discharge housing 1 and is used to drive the rotating part 21 to rotate.

[0045] The above-mentioned powder blocking structure forms an accommodating space by the limiting plate 3, and ensures its adaptability to the accommodating space by ensuring the structural accuracy of the limiting part 22. The rotating part 21 and the limiting part 22 can jointly support the material blocking part 23. The structure is compact and simple, which is convenient for reducing the processing amount of the baffle 2 and effectively strengthening the partial structural strength of the baffle 2.

[0046] In one embodiment, a sealing ring 5 is further provided at the powder outlet 101, and the sealing ring 5 is in close contact with the baffle plate 2 by pressing the upper surface of the material blocking portion 23. Specifically, the sealing ring 5 is made of elastic rubber material. In this way, the sealing ring 5 is in close contact with the material blocking portion 23 of the baffle plate 2 after elastic deformation, thereby playing a good powder blocking role.

[0047] In one embodiment, a top contact strip 51 is provided at one end of the sealing ring 5 facing the baffle plate 2; the top contact strip 51 at least includes a first contact strip 52 and a second contact strip 53 disposed outside the first contact strip 52, and the protruding height of the second contact strip 53 is lower than the protruding height of the first contact strip 52. In this way, when the driving component 4 drives the rotating part 21 to rotate, the blocking part 23 first contacts the second contact strip 53 and then contacts the first contact strip 52, the second contact strip 53 has a small elastic deformation and the first contact strip 52 has a large deformation, so that a double sealing effect is achieved.

[0048] like Figure 4 and Figure 5 As shown, in one embodiment, the driving component 4 includes a driving motor 41 with an output shaft, a lever 42 connected to the output shaft hub, a mounting block 43 disposed at the end of the output shaft, and a first switch 44 and a second switch 45 disposed on both sides of the lever 42; the material stopper 23 is connected to the mounting block 43. In this way, the lever 42 is driven to rotate by the driving motor 41, so that the lever 42 touches the detection contacts of the first switch 44 and the second switch 45 respectively, thereby detecting the actual rotation position of the baffle 2.

[0049] In one embodiment, the detection contact of the first switch 44, the rotation center of the output shaft, and the detection contact of the second switch 45 form a rotation angle, and the angle range of the rotation angle is 30° to 70°. In this way, by limiting the angle range of the rotation angle to 30° to 70°, it is ensured that the baffle 2 can achieve the switching of the powder outlet 101 being fully opened and fully closed through the drive of the drive motor 41.

[0050] In one embodiment, the mounting block 43 is provided with a first mounting hole connected to the output shaft hub, and a second auxiliary hole group arranged at intervals along the circumference of the first mounting hole. Specifically, the second auxiliary hole group includes at least two mounting through holes, and the rotating part 21 is provided with a connecting through hole adapted to the first mounting hole and the second auxiliary hole. In this way, the baffle 2 is fixedly mounted on the mounting block 43 by three mounting through holes, ensuring the connection strength between the rotating part 21 and the mounting block 43.

[0051] In one embodiment, the first mounting hole is a rectangular hole, and the output shaft is provided with a rectangular portion adapted to the rectangular hole.

[0052] In one embodiment, a contact flange 31 is provided on one side of the limit plate 3 close to the baffle plate 2. Thus, the contact flange 31 is used to form an accommodation space adapted to the thickness of the baffle plate 2, reducing the processing area of ​​the actual contact between the limit plate 3 and the baffle plate 2, thereby reducing costs.

[0053] On the other hand, Figure 1 and Figure 6As shown, a bean grinding coffee machine in one embodiment of the utility model includes a mounting shell 6, a powder blocking structure 7, and a grinding component 8 arranged above a powder outlet 101; the grinding component 8 is provided with a grinding outlet 801 connected to the powder outlet 101.

[0054] In a specific embodiment, a shower head 9 is further included on the mounting housing 6. Specifically, the shower head 9 has a hot water outlet, and the bean coffee machine sprays hot water to the bottom of the powder outlet 101 through the hot water outlet to mix with the coffee powder dropped from the powder outlet 101.

[0055] In one embodiment, the mounting shell 6 is provided with a mounting opening 601, which is arranged outside the inlet end of the powder outlet 101, and the grinding outlet 801 is arranged inside the outlet end of the powder outlet 101. In this way, by sequentially arranging the grinding outlet 801, the inlet end of the powder outlet 101, and the mounting opening 601 from the inside to the outside, the grinding outlet 801 and the inlet end of the powder outlet 101 are guided and installed by using the mounting opening 601, so as to prevent the coffee beans from leaking out from the connection gap after the grinding component 8 is ground into coffee powder.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
