Description

Technical Field

[0001] This utility model relates to a linkage mechanism for a capsule coffee machine, and more particularly to a linkage mechanism having an outer cover and a brewing chamber cover. Background Technology

[0002] The lid of the brewing chamber in existing capsule coffee machines serves to both create and seal the brewing space. Opening and closing the lid typically requires a separate switch mechanism, which usually doesn't have any other function. The water tray of the capsule coffee machine is located below the brewing chamber and is used to hold the coffee cup. However, as the brewed coffee drips onto the cup, it splashes. The water tray usually doesn't have a large enough surface area or a high enough platform, so the splashed coffee stains the work surface and reduces the user experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a capsule coffee machine with a mask assembly and its linkage mechanism to overcome the defects such as coffee splashing in the prior art.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a lid linkage mechanism for a capsule coffee machine, including a housing, a lid rotatably connected to the housing, a brewing component installed on the housing, the lid being used to close the brewing component, and a mask assembly, the mask assembly being rotatably connected to the housing, the mask assembly driving the lid to open and close when it rotates.

[0005] Furthermore, the mask assembly drives the cover via an intermittent motion mechanism.

[0006] Furthermore, the maximum angle at which the mask assembly rotates open relative to the housing is greater than the maximum angle at which the cover rotates open relative to the housing.

[0007] Furthermore, the intermittent motion mechanism includes a first gear, a transition gear, and a second gear. When the mask assembly rotates, it drives the first gear to rotate. The first gear drives the second gear to rotate intermittently through the transition gear. When the second gear rotates, it drives the cover to rotate.

[0008] Furthermore, the transition gear includes a fully gear and an incomplete gear that rotate synchronously on the same axis. The fully gear meshes with the first gear, and the incomplete gear meshes with the second gear. The incomplete gear has an intermittent section.

[0009] Furthermore, the rotation radius of the complete gear and the incomplete gear is the same.

[0010] Furthermore, the maximum angle at which the mask assembly rotates open relative to the housing is equal to the maximum angle at which the cover rotates open relative to the housing.

[0011] Furthermore, the mask assembly includes a mask frame and a cover mounted on the mask frame.

[0012] Furthermore, the mask assembly and the housing form an accommodating space, and the mask body covers the accommodating space.

[0013] Furthermore, the intermittent motion mechanism is any one of a cam mechanism, a linkage mechanism, or a Geneva mechanism.

[0014] Compared with the prior art, the advantages of this utility model are that, without increasing the overall size of the capsule coffee machine, a mask assembly that is rotatably connected to the shell is set up, which serves as both a splash-proof shield and a cover opening and closing drive mechanism; the mask assembly and the cover are connected by an intermittent motion mechanism, which reduces the user's operating difficulty and improves the user experience.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] Reference Figure 1-8 The capsule coffee machine of this invention includes a housing 300, a cover 200 rotatably mounted on the housing 300, and a mask assembly 100 rotatably mounted on the housing 300. The mask assembly 100 includes a mask frame 110 and a cover 111 mounted on the mask frame 110. The mask assembly 100 is connected to the cover 200 via an intermittent motion mechanism, and the intermittent motion mechanism drives the cover 200 to rotate.

[0019] In one embodiment, the housing 300 includes a first mounting position 310 for rotatably mounting the face mask assembly 100, a second mounting position 321 for rotatably mounting the cover 200, and a third mounting position 330 for mounting the transition gear 130, as shown below. Figure 3 , Figure 4 As shown.

[0020] In one embodiment, the transition gear 130 is rotatably connected to the first gear 120 and the second gear 230. The first gear 120 is rotatably connected to the mask frame 110 via a first shaft 121, which is rotatably connected to the first mounting position 310. The second gear 230 is rotatably connected to the lower part of the cover 200 via the second shaft 231 and simultaneously rotatably connected to the second mounting position 321, thereby rotatably connecting the cover 200 to the housing 300. In one embodiment, the second mounting position 321 is located on the bracket 320, which is mounted on the housing 300.

[0021] In one embodiment, the transition gear 130 rotates about a third axis 131 to cause the first gear 120 and the second gear 230 to rotate in the same direction and synchronously. A portion of the transition gear 130 is an incomplete gear, used to cause the first gear 120 and the second gear 230 to rotate in the same direction but not completely synchronously. That is, the transition gear 130 actually includes two coaxially synchronously rotating gears: a complete gear composed of a complete tooth 134 and an incomplete tooth 132, and an incomplete gear composed of a complete tooth 134 and an intermittent segment 133. The complete gear is always engaged with the first gear 120 to transmit driving force from the mask assembly 100. The incomplete gear only transmits driving force to the second gear 230 when the incomplete tooth 132 is engaged with the second gear 230, and stops transmitting driving force during the intermittent segment 133, at which time the teeth of the second gear 230 only slide through the intermittent segment 133 without being driven. In one embodiment, as shown... Figure 7 and Figure 8 As shown, the intermittent segment 133 occupies a circumferential angle of δ on the incomplete gear, and the complete tooth 134 occupies a circumferential angle of (2π-δ) on the incomplete gear. When the tooth of the second gear 230 rotates to the intermittent segment 133, the transition gear 130 does not drive the second gear 230, and the tooth of the second gear 230 slides over the surface of the intermittent segment 133 without rotating to achieve the intermittent effect.

[0022] The specific intermittent effect is as follows: when the mask assembly rotates 100 degrees to an angle α, ... Figure 6 In the state shown, the angle β through which the cover 200 rotates, driven by the first gear 120, the transition gear 130, and the second gear 230, is less than α. That is, when the mask assembly 100 rotates by a large angle α, it only drives the cover 200 to rotate by a small angle β. This is because the opening angle of the mask assembly 100 is much larger than the opening angle of the cover 200 when a coffee capsule needs to be placed inside the brewing unit 600. Also, in order to ensure that the user does not have to pay attention to whether the opening angle is too large or whether the opening angle is sufficient to open the cover 200 when manually opening the mask assembly 100, the opening angle of the cover 200 does not need to be as large as the opening angle of the mask assembly 100. Of course, in a less desirable embodiment, and when the opening space of the cover 200 is not limited by nearby components, the opening angle of the cover 200 can be the same as the opening angle of the mask assembly 100. That is, in the embodiment where the first gear 120 and the second gear 230 rotate in the same direction and synchronously, the components near the cover 200 need to be designed to avoid each other, which will make the coffee machine's structure less compact.

[0023] In one embodiment, the rotation radii of the complete gear and the incomplete gear are the same; in another embodiment, the rotation radii of the complete gear and the incomplete gear are different, and those skilled in the art can set them accordingly according to the actual opening angle requirements.

[0024] In other embodiments, the first gear 120, the second gear 230, and the transition gear 130 may also be replaced by a cam mechanism, a linkage mechanism, a Geneva mechanism, or other intermittent motion mechanism, as those skilled in the art will understand, and will not be elaborated here.

[0025] In one embodiment, the housing 300 further includes a mounting platform 340, on which a bracket 320 is mounted. The brewing assembly 600 is mounted on the bracket 320. The cover 200 includes an upper cover 210 and a lower cover 220 connected to each other. An upper piercing component 221 is mounted on the lower cover 220, with its piercing needle facing the brewing assembly 600. This component is used to pierce the coffee capsule inside the brewing assembly 600 the instant the cover 200 is closed. After brewing, the coffee liquid flows out from the outlet 601 and falls into a coffee cup located on a drip tray 500. The space above the drip tray 500 for placing the coffee cup is a receiving space 101. Figure 3 As shown, splashed coffee liquid will be blocked by the cover 111 of the mask assembly 100 to prevent the work surface from getting dirty.

[0026] In one embodiment, the cover 111 is a transparent panel, such as a high-temperature resistant PC board or tempered glass plate, to facilitate user observation. In one embodiment, the cover 111 completely covers the accommodating space 101; in another embodiment, the cover 111 only partially covers the accommodating space 101. In one embodiment, the cover 111 can extend, retract, or move along the mask frame 110 to completely cover the accommodating space 101. In some embodiments, the cover 111 can be replaced as needed.

[0027] The working process of this utility model is as follows: The user manually or electrically rotates and lifts the mask assembly 100. The mask frame 110 drives the first gear 120 to rotate and drives the transition gear 130 to rotate. The transition gear 130 intermittently drives the second gear 230 to rotate. The second gear 230 drives the cover 200 to rotate and lift. The user places a coffee capsule into the brewing assembly 600 and a coffee cup into the receiving space 101. The user rotates and closes the mask assembly 100. During the process of the mask assembly 100 rotating and descending, the cover 200 closes first or simultaneously with the mask assembly 100. The moment the cover 200 closes or after it closes, the working switch of the capsule coffee machine is triggered, and the coffee machine starts brewing coffee. After brewing is completed, the coffee liquid flows into the coffee cup. Before the user rotates and lifts the mask assembly 100 again, the coffee machine stops working through internal program control, or the working switch of the coffee machine is turned off when rotating and lifting the mask assembly 100 or after lifting and before the cover 200 is opened, and the coffee machine stops working.
