[0004] The utility model also provides a coffee machine.

[0005] The coffee machine according to the first embodiment of the utility model comprises:

[0006] A brewing head, wherein a brewing cavity and a slag outlet communicated with the brewing cavity are formed on the brewing head;

[0007] A slag guide plate is arranged at one side of the slag outlet, and the slag guide plate extends from the slag outlet toward a preset slag discharge position. The slag guide plate has a guide surface that contacts the powder slag, and a guide protrusion is provided on the guide surface.

[0008] According to the coffee machine of the embodiment of the utility model, at least one ridge is provided on the guiding protrusion, and the ridge extends from the slag outlet toward the preset slag discharge position.

[0009] According to the coffee machine of the embodiment of the present invention, the residue guide plate is inclined from the residue outlet toward the preset residue discharge position, wherein the angle between the guide surface and the plane where the residue outlet is located is greater than or equal to 120° and less than or equal to 160°.

[0010] According to the coffee machine of the embodiment of the present invention, the number of the convex ridges is three, and the three convex ridges are arranged on the guide surface at intervals from each other.

[0011] According to the coffee machine of the embodiment of the utility model, the distance between the two convex ridges located at the outermost sides of the guide surface is less than or equal to the diameter of the powder residue.

[0012] The coffee machine according to the embodiment of the utility model further includes a slag shovel, which is installed on the movement path of the slag outlet and is located on the opposite side of the slag outlet and the slag guide plate when the slag outlet guides the powder residue. The slag shovel is suitable for resisting the powder residue at the slag outlet to prevent the powder residue from rotating with the brewing chamber.

[0013] According to the coffee machine of the embodiment of the utility model, the coffee machine further comprises a waste residue box, and the waste residue box is arranged at the preset residue discharge position.

[0014] According to the coffee machine of the embodiment of the present invention, the cross section of the convex ridge along its own length direction is square, hemispherical or trapezoidal.

[0018] The above one or more technical solutions in the embodiments of the utility model have at least one of the following technical effects:

[0019] The present application sets a slag guide plate between the slag outlet and the preset slag discharge position, and a guide surface for guiding the powder slag is formed on the slag guide plate, and a guide protrusion is protruding from the guide surface. When the powder slag slides from the guide surface to the process where the powder slag falls to the pre-trial slag discharge position, due to the addition of the guide protrusion on the guide surface, the powder slag changes from sliding on the plane of the guide surface to sliding on the guide protrusion. Therefore, the contact area between the powder slag and the guide surface is reduced, thereby reducing the friction coefficient of the powder slag on the discharge guide surface. According to the calculation formula of friction force F=μ*N, F is the friction force, μ is the friction coefficient, and N represents the positive pressure acting on the object. Here, the positive pressure N is the component force provided by the weight of the powder slag itself, so it is constant. In this way, it can be calculated that the friction force of the powder slag sliding on the guide protrusion is less than the friction force of the powder slag sliding directly on the guide surface. It is precisely because the friction force of the powder slag on the guide surface is reduced. Therefore, the adhesion between the powder residue and the residue guide plate can be effectively prevented, and the coffee residue can be prevented from remaining on the residue guide plate after the coffee machine is used, thereby saving the user the trouble of cleaning the residue guide plate after use, thereby improving the user experience.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0033] In the relevant technical field, the coffee machine's extractor coffee waste discharge guide has a smooth surface. When the extractor finishes brewing coffee, the mechanism moves to push the powder residue out of the brewing chamber. During the rotation of the brewing chamber, it is blocked by the waste residue scraper and uses the waste residue cake's own gravity to slide from the discharge guide rail and fall into the waste residue box.

[0034] The utility model provides a coffee machine.

[0035] In the embodiment of the present utility model, refer to Figure 1 and Figure 2A coffee machine 10 is provided, including a residue guide plate 100 and a brewing head 20, wherein a brewing chamber 21 and a residue outlet 22 connected to the brewing chamber are formed on the brewing head; the residue guide plate 100 is arranged at one side of the residue outlet 22, and the residue guide plate 100 extends from the residue outlet 22 toward a preset residue discharge position, and has a guide surface 110 in contact with the powder residue 30, and a guide protrusion is provided on the guide surface 110.

[0036] The slag guide plate 100 is the first component that the powder slag 30 contacts and slides along after being discharged from the slag outlet 22 of the brewing chamber 21. The main function of the slag guide plate 100 is to provide a clear sliding path for the powder slag 30 to ensure that the powder slag 30 can accurately fall into the preset slag discharge position. The preset slag discharge position is a storage point for the discharge of the powder slag 30 set as needed.

[0037] The slag guide plate 100 is arranged on one side of the slag outlet 22 of the brewing chamber 21, so that the powder slag 30 can immediately contact the slag guide plate 100 after being pushed out, thereby starting the sliding process. This layout helps to improve the efficiency and accuracy of slag discharge.

[0038] The slag guide plate 100 extends from the slag outlet 22 toward the preset slag discharge position, and the slag guide plate 100 extends in this direction to provide a continuous sliding path for the powder slag 30, thereby ensuring that the powder slag 30 can smoothly slide to the preset slag discharge position according to a predetermined trajectory.

[0039] The guide surface 110 is the part of the slag guide plate 100 that is in direct contact with the powder slag 30, and its design directly affects the sliding effect of the powder slag 30. The guide surface 110 needs to be smooth enough to reduce the friction between the powder slag 30 and promote the smooth sliding of the powder slag 30.

[0040] In one embodiment, at least one ridge 111 is provided on the guide protrusion, and the ridge 111 extends from the slag outlet 22 toward the preset slag discharge position. The presence of the ridge 111 changes the contact mode between the powder residue 30 and the guide surface 110, from the original plane contact to point or line contact, thereby significantly reducing the contact area. Due to the reduction in contact area, the friction between the powder residue 30 and the guide surface 110 is also reduced, making the powder residue 30 easier to slide. The reduced friction reduces the possibility of adhesion between the powder residue 30 and the guide surface 110, which helps to reduce the residue residue on the slag guide plate 100. The ridge 111 can also play a guiding role, ensuring that the powder residue 30 maintains the correct direction during the sliding process, further reducing the possibility of residue and blockage.

[0041] The present application sets a slag guide plate 100 between the slag outlet 22 and the preset slag discharge position, and a guide surface 110 for guiding the powder slag 30 is formed on the slag guide plate 100, and a guide protrusion is protruding from the guide surface 110. When the powder slag 30 slides from the guide surface 110 to the process of the powder slag 30 falling to the pre-trial slag discharge position, due to the guide protrusion added to the guide surface 110, the powder slag 30 changes from the original plane sliding with the guide surface 110 to the powder slag 30 sliding on the guide protrusion. Therefore, the contact area between the powder slag 30 and the guide surface 110 is reduced, thereby reducing the friction coefficient of the powder slag 30 on the discharge guide surface 110. According to the calculation formula of friction force F=μ*N, F is the friction force, μ is the friction coefficient, and N represents the positive pressure acting on the object. The positive pressure N here is the component force provided by the weight of the powder slag 30 itself, so it is constant. In this way, it can be calculated that the friction force of the powder residue 30 sliding on the guide protrusion is smaller than the friction force of the powder residue 30 sliding directly on the guide surface 110. It is precisely because the friction force of the powder residue 30 on the guide surface 110 is reduced that the powder residue 30 can be effectively prevented from sticking to the residue guide plate 100, and the coffee residue can be prevented from remaining on the residue guide plate 100 after the coffee machine is used, eliminating the trouble of the user cleaning the residue guide plate 100 after use, thereby improving the user's use experience.

[0042] Reference Figure 1 and Figure 2 According to the coffee machine 10 of the embodiment of the present invention, the slag guide plate 100 is inclined from the slag outlet 22 toward the preset slag discharge position, wherein the angle between the guide surface 110 and the plane where the slag outlet is located is greater than or equal to 120° and less than or equal to 160°.

[0043] It is understandable that in the present embodiment, the residue guide plate 100 is tilted, so that the gravity of the powder residue 30 itself can be used to help the powder residue 30 slide down smoothly. When the powder residue 30 is on the residue guide plate 100, gravity will cause it to slide down along the tilted residue guide plate 100 until it reaches the preset residue discharge position. This can reduce the additional push demand for the powder residue 30 to slide down inside the coffee machine, and improve the efficiency and smoothness of the residue discharge. At the same time, the tilted residue guide plate 100 helps the powder residue 30 maintain a certain speed and continuity during the sliding process, reducing the possibility of staying and accumulating on the residue guide plate 100. The residue on the residue guide plate 100 is reduced. This not only improves the overall cleanliness of the coffee machine, but also reduces the frequency of users cleaning the residue guide plate 100, thereby improving the user experience.

[0044] Optionally, the angle between the guide surface 110 and the plane where the slag outlet is located can be 120°, 121°, 122°, 123°, 124°, 125°, 126°, 127°, 128°, 129°, 130°, 131°, 132°, 133°, 134°, 135°, 136°, 137°, 138°, 139°, 140°, 141°, 142°, 143°, 144°, 145°, 146°, 147°, 148°, 149°, 150°, 151°, 152°, 153°, 154°, 155°, 156°, 157°, Any angle among 1°, 142°, 143°, 144°, 145°, 146°, 147°, 148°, 149°, 150°, 151°, 152°, 153°, 154°, 155°, 156°, 157°, 158°, 159° or 160° is not particularly limited in the present application and can be set according to needs such as gravity of powder residue.

[0045] Reference Figure 1 and Figure 2 According to the coffee machine 10 of the embodiment of the present invention, the number of the ridges 111 is three, and the three ridges 111 are arranged on the guide surface 110 at intervals from each other.

[0046] It is understandable that the spaced arrangement of the three ridges 111 makes the contact of the powder residue 30 on the guide surface 110 more uniform. Each ridge 111 can bear a part of the weight and friction of the powder residue 30, thereby evenly dispersing the total friction. It can reduce the friction concentration caused by single-point contact, allowing the powder residue 30 to slide more smoothly. The spaced arrangement of the three ridges 111 provides multiple support points for the powder residue 30 to slide. These support points can ensure that the powder residue 30 maintains a stable posture during the sliding process, and prevent it from deviating from the predetermined path due to the displacement or shaking of the center of gravity. It helps to reduce the deviation and residue of the powder residue 30 during the sliding process.

[0047] Reference Figure 1 and Figure 2 According to the coffee machine 10 of the embodiment of the present invention, the distance between the two convex ridges 111 located on the outermost sides of the guide surface 110 is less than or equal to the diameter of the powder residue 30.

[0048] It is understandable that the present application ensures that the powder residue 30 is always covered and guided by the ridges 111 during the sliding process by ensuring that the spacing between the two outermost ridges 111 is less than or equal to the diameter of the powder residue 30. It can effectively prevent the powder residue 30 from deviating from the predetermined path due to loss of contact when sliding, and ensure that the powder residue 30 can accurately slide to the preset slag discharge position. Since the spacing between the two outermost ridges 111 is less than or equal to the diameter of the powder residue 30, the powder residue 30 provides a stronger guiding effect. When the powder residue 30 slides, it will contact multiple ridges 111 at the same time. These ridges 111 work together on the powder residue 30 to keep it in a stable posture and sliding trajectory. The stability and accuracy of the sliding of the powder residue 30 are further improved.

[0049] Sum by reference Figure 2 According to the coffee machine 10 of the embodiment of the present invention, it also includes a slag shovel 200, which is installed on the movement path of the slag outlet 22 and is located on the opposite side of the slag outlet 22 and the slag guide plate 100 when the slag outlet 22 guides the powder slag. The slag shovel 200 is suitable for resisting the powder slag 30 at the slag outlet 22 to prevent the powder slag 30 from rotating with the brewing chamber 21.

[0050] It can be understood that the slag shovel 200 is fixedly provided on one side of the slag outlet 22 opposite to the slag guide plate 100. When the powder slag 30 is completely pushed out of the brewing chamber 21, the brewing chamber 21 rotates toward the other side opposite to the slag guide plate 100 under the drive of the driving mechanism, and the powder slag 30 is blocked by the slag shovel 200. After the brewing chamber 21 rotates out, the powder slag 30 will fall onto the guide surface 110 of the slag guide plate 100, and extend the guide surface 110 to slide under its own action, and finally fall into the pre-slag discharge position. In this way, the slag shovel 200 and the slag guide plate 100 in the coffee machine 10 work together to ensure that the powder slag 30 can be discharged smoothly and completely after brewing is completed, thereby improving the degree of automation of the coffee machine.

[0051] Reference Figure 1 and Figure 2 According to the coffee machine 10 of the embodiment of the present invention, the coffee machine 10 further includes a waste residue box 300, and the waste residue box 300 is arranged at a preset residue discharge position.

[0052] It is understandable that when the powder residue 30 is pushed out of the brewing chamber 21 after brewing is completed, the slag shovel 200 will block the powder residue 30 to prevent it from rotating with the brewing chamber 21. Then, the powder residue 30 will slide down to the guide surface 110 of the residue guide plate 100 under the action of its own gravity, and slide along the guide surface 110. Finally, the waste powder residue 30 will accurately fall into the waste residue box 300, completing the entire residue discharge process. The waste residue box 300 is mainly suitable for collecting and accommodating the waste powder residue 30 that slides down from the residue guide plate 100. In this way, the waste powder residue 30 can be effectively collected, avoiding the waste residue from being scattered inside the coffee machine or in the surrounding environment, thereby improving the cleanliness and convenience of the coffee machine.

[0053] Optionally, the cross section of the ridge 111 along its own length direction is square, hemispherical or trapezoidal.

[0054] It is understandable that the design of the square ridge 111 can provide a relatively smooth sliding surface, so that the powder residue 30 remains stable during the sliding process. At the same time, the square ridge 111 has clear edges and corners, which can help the powder residue 30 to separate better when sliding and avoid adhesion. The design of the hemispherical ridge 111 can provide a smoother sliding surface, so that the powder residue 30 is subject to less resistance during the sliding process. In addition, the curved surface design of the hemispherical ridge 111 can also reduce the wear and breakage of the powder residue 30 during the sliding process. The design of the trapezoidal ridge 111 combines the characteristics of the square and hemispherical ridges 111. Its bottom is wider, which can provide stable support; the top is narrower, which is conducive to the separation and sliding of the powder residue 30.

[0055] Reference Figure 1 and Figure 2 According to the coffee machine 10 of the embodiment of the present invention, the outer edges of both sides of the guide surface 111 are provided with a panel 112, the panel 112 extends along the extension direction of the ridge, and a protrusion 112a is protruded from the middle of the panel 112.

[0056] It is understood that the main function of the enclosure 112 is to prevent the powder residue 30 from deviating from the predetermined sliding path during the sliding process, and to ensure that the powder residue 30 can accurately fall into the waste residue box 300. The height and width of the enclosure 112 can be adjusted according to the size and shape of the powder residue 30 to ensure that it can effectively prevent the deviation of the powder residue 30. The role of the protrusion 112a is to provide additional support and guidance during the sliding process of the powder residue 30. When the powder residue 30 contacts the protrusion 112a, they will help the powder residue 30 to slide better along the guide surface 110.

[0057] Reference Figure 1 According to the coffee machine 10 of the embodiment of the utility model, the ridge 111 is provided with a first guide slope 111a and a second guide slope 111b at opposite ends along its own extension direction, respectively. The first guide slope 111a is inclined from the guide surface 110 toward the top of the ridge 111, and the second guide slope 111b is inclined from the top of the ridge 111 toward the guide surface 110.

[0058] It is understandable that the first guide bevel 111a is inclined from the guide surface 110 toward the top of the ridge 111. This helps the powder residue 30 to smoothly transition to the top of the ridge 111 when it contacts the ridge 111, reducing resistance and preventing the powder residue 30 from being stuck or broken during the sliding process. The second guide bevel 111b is inclined from the top of the ridge 111 toward the guide surface 110. After passing the top of the ridge 111, the powder residue 30 can smoothly slide back to the guide surface 110 and continue to slide down along the guide surface 110 until it falls into the waste residue box 300. The design of the first bevel and the second bevel allows the powder residue 30 to smoothly transition during the sliding process, reducing resistance and improving the sliding efficiency.

[0059] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
