Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to an anti-blocking structure of a coffee machine. Background Art

[0002] Coffee machines combine the functions of grinding coffee beans and brewing coffee powder, and are widely used in daily life. Usually, coffee beans are ground into coffee powder through a grinding mechanism, and then the coffee powder is sent into a brewing container through a powder channel. After the heating mechanism heats water, the water is injected into the brewing container to brew the coffee powder, thereby producing coffee liquid suitable for drinking. However, during the process of crushing and grinding coffee beans, static electricity is generated due to the friction between the coffee beans and the blade assembly. The coffee powder carries a certain amount of charge, which will cause the problem of flying powder. In addition, the coffee powder has a certain oil content. Therefore, coffee powder is generally easy to accumulate on the powder outlet channel, causing the powder outlet channel to be blocked, affecting the taste of the coffee, and poor user experience.

[0003] In May 2023, Chinese patent document CN219088935U disclosed an automatic grinding and conveying structure for preventing powder blockage and a coffee machine thereof. Specifically, the invention discloses a grinding device, a powder pushing device, and a powder dropping channel. The grinding device includes a grinding chamber and a rotating grinding wheel disposed in the grinding chamber. A grinding channel is formed between the inner peripheral wall of the grinding chamber and the outer peripheral wall of the rotating grinding wheel. The grinding channel has a powder inlet. The powder pushing device includes a powder receiving chamber located below the powder inlet and a rotating push plate disposed in the powder receiving chamber. A powder discharge port is provided on the inner peripheral wall of the powder receiving chamber. The rotating push plate is used to push the powder toward the powder discharge port. The powder dropping channel has a guide section and a powder dropping section. The guide section is tilted downward and one end of the guide section is connected to the powder discharge port. The powder dropping section is vertically downward and the powder dropping section is connected to the other end of the guide section. The structure of the powder dropping channel in the above-mentioned patent document is relatively complex, and coffee powder may still accumulate in the powder receiving chamber, the guide section, or the powder dropping section.

[0004] Therefore, further improvement is needed. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide an anti-blocking structure for a coffee machine to overcome the shortcomings of the prior art. The powder outlet channel can effectively prevent coffee powder from gathering on the powder outlet channel through the retaining ribs, thereby avoiding the problem of blockage.

[0006] An anti-blocking structure of a coffee machine designed for this purpose includes a powder outlet channel connected to a grinding chamber, the powder outlet channel being provided with guide ribs for preventing coffee powder from accumulating in the powder outlet channel, the guide ribs dividing the powder outlet channel into a first anti-blocking area and a second anti-blocking area.

[0007] The guide rib is arranged on the powder inlet of the powder outlet channel, and the powder outlet channel also includes a connecting cavity connected to the first anti-blocking area and the second anti-blocking area. The first anti-blocking area, the second anti-blocking area and the connecting cavity are smoothly transitioned.

[0008] The powder outlet channel is arranged in an arc shape.

[0009] A powder discharge inclined wall is provided on the powder inlet of the powder discharge channel, and the guide rib is arranged to extend in an oblique arc shape from the powder discharge inclined wall and the first anti-blocking area toward the second anti-blocking area.

[0010] The area of ​​the second anti-blocking region is larger than the area of ​​the first anti-blocking region.

[0011] The guide rib includes a first blocking surface, which forms an angle a with the inner side wall of the first anti-blocking area, 30°≤a≤80°; the guide rib also includes a second blocking surface, which forms an angle b with the inner side wall of the second anti-blocking area, 100°≤b≤130°.

[0012] The powder outlet channel and the guide rib are an integrally formed structure or a separate structure.

[0013] The anti-blocking structure also includes an ion generator. The powder outlet channel is provided with a connecting structure for fixing the ion generator. The connecting structure includes a first connecting column and a second connecting column. The ion generator is fixedly mounted on the first connecting column and the second connecting column by screws.

[0014] The powder outlet channel is further provided with a blocking structure, which is located on the first connecting column and includes a first blocking rib and a second blocking rib.

[0015] The anti-blocking structure also includes a grinding bracket, which is provided with a fixing portion for positioning the powder outlet channel. The powder outlet channel is provided with a positioning seat, which is inserted into the fixing portion to achieve the positioning and installation of the powder outlet channel on the grinding bracket.

[0016] The anti-blocking structure of a coffee machine in the above-mentioned embodiment includes a powder discharge channel connected to the grinding chamber. The powder discharge channel is provided with guide ribs for preventing coffee powder from accumulating in the powder discharge channel. The guide ribs divide the powder discharge channel into a first anti-blocking area and a second anti-blocking area. Specifically, before coffee powder is pushed into the powder discharge channel and hits the first and second anti-blocking areas, it first hits the guide ribs, causing the coffee powder to be dispersed by the guide ribs and then discharged from the first and second anti-blocking areas. This effectively prevents the continued accumulation of coffee powder and the resulting lumps from adhering to the powder discharge channel, causing a blockage. Thus, altering the powder discharge channel and the guide ribs allows coffee powder to fall smoothly, greatly improving problems such as powder blockage, powder obstruction, and powder storage.

[0026] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1-Figure 5 As shown, an anti-blocking structure of a coffee machine is provided, including a powder outlet channel 1 connected to the grinding chamber, and a guide rib 2 is provided on the powder outlet channel 1 for preventing coffee powder from accumulating on the powder outlet channel 1. The guide rib 2 divides the powder outlet channel 1 into a first anti-blocking area 101 and a second anti-blocking area 102.

[0028] Specifically, before the coffee powder is pushed into the powder outlet channel 1 and hits the first anti-blocking area 101 and the second anti-blocking area 102, the coffee powder will first hit the guide rib 2, so that the coffee powder is scattered by the guide rib 2 and then discharged from the first anti-blocking area 101 and the second anti-blocking area 102, thereby effectively preventing the continuously pushed in coffee powder from accumulating into lumps and sticking to the powder outlet channel 1, causing powder blockage; it can be seen that changing the powder outlet channel 1 and the guide rib 2 allows the coffee powder to fall smoothly, which greatly improves the phenomena of powder blockage, powder obstruction, and powder storage.

[0029] Further, if Figure 1-Figure 5 As shown, the guide rib 2 is arranged on the powder inlet 103 of the powder outlet channel 1, and the powder outlet channel 1 also includes a connecting cavity 104 connected to the first anti-blocking area 101 and the second anti-blocking area 102. The first anti-blocking area 101, the second anti-blocking area 102 and the connecting cavity 104 are smoothly transitionally connected.

[0030] Specifically, the guide rib 2 is arranged above the powder outlet channel 1, which can guide the coffee powder to fall naturally along the powder outlet channel 1 to avoid the coffee powder from gathering;

[0031] The interior of the powder outlet channel 1 usually adopts a smooth transition connection, or a smooth material or coating to reduce the adhesion of coffee powder in the channel. Such a design can effectively prevent the accumulation of coffee powder on the powder outlet channel 1, ensuring the normal operation of the coffee machine and a good user experience.

[0032] Further, if Figure 1 、 Figure 2 and Figure 5 As shown, the powder outlet channel 1 is arranged in an arc shape.

[0033] Specifically, the powder outlet channel 1 and the guide ribs 2 arranged in an arc shape can effectively prevent coffee powder from gathering on the powder outlet channel 1, thereby avoiding the problem of blockage.

[0034] The arc-shaped setting of the powder outlet channel 1 can also prevent coffee powder from gathering at the powder inlet 103 of the powder outlet channel 1. The arc-shaped channel design can make the coffee powder flow into the next stage more stable and smooth, while also preventing coffee powder from accumulating at the powder inlet 103 of the powder outlet channel 1.

[0035] Further, if Figure 1 and Figure 2 As shown, a powder discharge inclined wall 105 is provided on the powder inlet 103 of the powder discharge channel 1 , and the guide rib 2 is arranged to extend in an oblique arc shape from the powder discharge inclined wall 105 and the first anti-blocking area 101 toward the second anti-blocking area 102 .

[0036] Specifically, in order to prevent the coffee powder from flying to both sides due to the action of gravity when entering the powder outlet channel 1, it also facilitates the coffee powder to be discharged smoothly along the powder outlet channel 1 under the guidance of the guide ribs 2, thereby avoiding the accumulation and blockage of coffee powder.

[0037] Further, if Figure 1 、 Figure 2 and Figure 5 As shown, the area of ​​the second anti-blocking region 102 is larger than the area of ​​the first anti-blocking region 101 .

[0038] Specifically, the scraper disk 7 rotates clockwise, evenly scraping the coffee powder onto the powder outlet channel 1. Once the coffee powder enters the powder outlet channel 1, it is first carried to the first anti-blocking area 101 and then to the second anti-blocking area 102. Because the second anti-blocking area 102 is larger than the first anti-blocking area 101, the coffee powder has ample space to flow freely during this process, preventing accumulation within the powder outlet channel 1. This design ensures smooth flow of coffee powder within the powder outlet channel 1, ensuring efficient operation of the coffee machine while preventing accumulation of coffee powder within the powder outlet channel 1, which could affect the discharge efficiency and even cause blockage.

[0039] Further, if Figure 5 As shown, the guide rib 2 includes a first blocking surface 201, which forms an angle a with the inner wall of the first anti-blocking area 101, 30°≤a≤80°; the guide rib 2 also includes a second blocking surface 202, which forms an angle b with the inner wall of the second anti-blocking area 102, 100°≤b≤130°.

[0040] Specifically, the design of the guide rib 2 can help to effectively transport and separate the coffee powder in the powder outlet channel 1, ensuring that the coffee powder will not gather on the powder outlet channel 1, nor will it adhere excessively to the inner walls of the first anti-blocking area 101 and the second anti-blocking area 102; at the same time, the angle a and the angle b of the guide rib 2 are designed to achieve the best separation effect.

[0041] Preferably, the angle a is 30°, or 35°, or 40°, or 45°, or 50°, or 55°, or 60°, or 65°, or 70°, or 75°, or 80°;

[0042] The angle b is 100°, or 105°, or 110°, or 115°, or 120°, or 125°, or 130°.

[0043] Furthermore, the powder outlet channel 1 and the guide rib 2 are an integrally formed structure or a separate structure.

[0044] Specifically, the powder outlet channel 1 and the guide rib 2 can be an integrated structure or a separate structure. When the powder outlet channel 1 and the guide rib 2 are an integrated structure, the powder outlet channel 1 and the guide rib 2 are processed at the same time, thereby simplifying the assembly steps and effectively improving the assembly efficiency; when the powder outlet channel 1 and the guide rib 2 are a split structure, the powder outlet channel 1 and the guide rib 2 are manufactured separately, and then the two are connected and fixed by riveting, welding or screw connection.

[0045] Further, if Figure 6 and Figure 7 As shown, the anti-blocking structure also includes an ion generator 3. A connecting structure 106 for fixing the ion generator 3 is provided on the powder outlet channel 1. The connecting structure 106 includes a first connecting column 1061 and a second connecting column 1062. The ion generator 3 is fixedly mounted on the first connecting column 1061 and the second connecting column 1062 by screws.

[0046] Specifically, the grinding assembly 6 grinds the coffee beans into powder, and the ion generator 3 forms an electrostatic protection layer on the surface of the powder to prevent the static electricity generated by the powder during the grinding process from damaging the equipment, and also helps separate the coffee powder;

[0047] The ion generator 3 is fixedly mounted on the powder outlet channel 1 via the connection structure 106 , which allows the ion generator 3 to maintain a relatively stable position during operation, thereby preventing the grinding assembly 6 from shaking significantly during operation.

[0048] Further, if Figure 6 and Figure 7 As shown, a blocking structure 4 is further provided on the powder outlet channel 1 . The blocking structure is located on the first connecting column 1061 . The blocking structure 4 includes a first blocking rib 401 and a second blocking rib 402 .

[0049] Specifically, the first blocking rib 401 and the second blocking rib 402 are staggered. In order to prevent coffee powder on the first anti-blocking area 101 from remaining on the first connecting column 1061, the first blocking rib 401 and the second blocking rib 402 are provided on the first connecting column 1061 to prevent coffee powder from gathering on the first connecting column 1061.

[0050] Further, if Figure 6 and Figure 7 As shown, the anti-blocking structure also includes a grinding bracket 5, which is provided with a fixing portion 501 for positioning the powder outlet channel 1. The powder outlet channel 1 is provided with a positioning seat 107, which is inserted into the fixing portion 501 to achieve the positioning of the powder outlet channel 1 on the grinding bracket 5.

[0051] With the above arrangement, the positioning seat 107 and the fixing portion 501 cooperate with each other, and the connection is stable and the assembly and disassembly are convenient, which is conducive to improving the cleaning convenience of the powder outlet channel 1.

[0052] Further, if Figure 6 and Figure 7 As shown, the anti-blocking structure also includes a grinding assembly 6 and a powder scraping plate 7 installed in the grinding bracket 5. The powder scraping plate 7 pushes the coffee powder ground by the grinding assembly 6 to the powder outlet channel 1.

[0053] Further, if Figure 6 and Figure 7 As shown, the anti-blocking structure further includes a driving motor 8 for driving the grinding assembly 6 to rotate.
