Description

Technical Field

[0001] This utility model relates to a coffee machine with a drawer-type capsule holder, and more specifically to a drawer lid with a displacement compensation mechanism. Background Technology

[0002] In capsule coffee machines, the drawer-style capsule holder makes it possible to accommodate capsules of different sizes. Typically, the drawer frame can accommodate different capsule holder sizes. To use it, simply pull out the drawer, insert the desired capsule holder and the compatible capsule, and push the drawer into the brewing chamber to begin brewing / brewing. During the high-pressure brewing process, the brewing assembly above the capsule holder compresses it with significant pressure, causing slight deformation. This can cause the drawer lid, which acts as the external handle, to sink, potentially squeezing and deforming the surrounding outer casing of the coffee machine, resulting in both unsightly appearance and safety hazards. Some coffee machines include a gap in the outer casing around the drawer lid to avoid this, but this reduces the user experience. Additionally, in some capsule coffee machines, the drawer is not suspended but adjacent to other components (such as the outer casing). When the drawer and drawer lid sink, they can compress these other components.

[0003] Chinese utility model patent CN217852457U discloses a brewing support for a drawer-type capsule coffee machine, including a coffee hopper equivalent to a drawer, which can be moved laterally out or pushed in through an opening in the side wall of the brewing support, and the coffee hopper having a closing part equivalent to a drawer lid, the closing part being fixedly connected to the main body of the coffee hopper; Chinese utility model patent CN219422615U discloses a coffee brewing mechanism, including a coffee compartment equivalent to a drawer, and a handle equivalent to a drawer lid, the handle being fixedly connected to the coffee compartment; Chinese utility model patent CN219594336U discloses a capsule support assembly for a capsule coffee machine, which has a drawer base equivalent to a drawer, and a handle equivalent to a drawer lid or directly connected to the drawer lid, the handle being fixedly connected to the drawer base. In all of the above cases, the drawer and drawer lid are fixedly connected, therefore, it is impossible to avoid sinking due to strong pressure during high-pressure brewing, thus creating a gap between the coffee machine casing and the drawer lid, potentially causing compression or even damage to other components below.

[0004] content

[0005] The technical problem to be solved by this utility model is to provide a drawer cover with a displacement compensation mechanism to overcome the above-mentioned defects in the prior art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: a drawer cover displacement compensation mechanism for a drawer of a capsule coffee machine. The drawer includes a body and a drawer cover that are connected to each other. The body is used to install different coffee capsules. The body and the drawer cover are rotatably connected, and there is a rotation reset mechanism between the body and the drawer cover. The rotation reset mechanism makes the drawer cover have an upward rotation tendency.

[0007] Furthermore, the rotation reset mechanism includes an arm and a limiting part, the arm having a free end that contacts the limiting part.

[0008] Furthermore, in the non-working state, the free end contacts the limiting part, the drawer cover rotates upward relative to the plane of the body, and there is an acute angle between the drawer cover and the body; in the working state, the free end and the limiting part press against each other, so that the drawer cover always has an upward rotation tendency.

[0009] Furthermore, the arm and the limiting part are respectively located on the body and the drawer lid.

[0010] Furthermore, the outer wall of the body extends into a platform towards the drawer lid, the platform having a hole, the arm being located within the hole, and the tip of the free end extending out from the hole.

[0011] Furthermore, the number of holes is greater than or equal to 1, and the number of arms is greater than or equal to 2.

[0012] Furthermore, there is a gap between the body and the drawer lid, which serves to prevent interference between the two when the drawer lid rotates relative to the body within the acute angle range.

[0013] Furthermore, the main body includes a first connecting portion, and the drawer lid includes a second connecting portion, wherein the first connecting portion and the second connecting portion are rotatably connected.

[0014] Furthermore, the first connecting part has a connecting hole, and the second connecting part has a rotating shaft that rotates within the connecting hole.

[0015] Furthermore, the rotation reset mechanism is a torsion spring, and the body and the drawer cover are respectively connected to the two arms of the torsion spring.

[0016] Compared with the prior art, the advantages of this utility model are that it makes full use of the structure of the body and the drawer cover to form a rotation reset mechanism without the need for other additional parts. Since the body and the drawer cover are integrally molded, it helps to reduce manufacturing and assembly costs. The displacement compensation effect is stable and reliable by utilizing the elastic deformation of the plastic parts themselves. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1-6The drawer of this utility model includes a body 100 and a drawer cover 200, which are rotatably connected. The body 100 and drawer cover 200 are typically integrally molded plastic parts. The body 100 includes a support 110 with a mounting position 111. The mounting position 111 can be replaced with different capsule holders to accommodate different capsules according to the user's needs. The support 110 extends outward to form a platform 120 and a first connecting portion 130. The drawer cover 200 has a cover body 210, a second connecting portion 220, and a limiting portion 230. The first connecting portion 130 and the second connecting portion 220 are rotatably connected. In one embodiment, the first connecting portion 130 includes a connecting hole 131, and the second connecting portion 220 includes a rotating shaft 221, which can rotate freely within the connecting hole 131. The connecting hole 131 can be a blind hole or a through hole, and the positions of the rotating shaft 221 and the connecting hole 131 can be interchanged. In one embodiment, there are two pivots 221 and two connecting holes 131, which are symmetrically located on both sides of the drawer cover 200. In another embodiment, there is a gap 300 between the first connecting part 130 and the drawer cover 200, which prevents interference between the two when the drawer cover 200 rotates relative to the body 100.

[0027] In one embodiment, platform 120 extends horizontally outward, such as Figure 4 and Figure 5 As shown, the platform 120 has a hole 101, from which an elastic arm 121 extends outward. The tip of the free end 122 of the arm 121 protrudes from the upper opening of the hole 101. A limiting part 230 protrudes from the inner surface of the cover 210 toward the support 110. In the non-working state, the tip of the free end 122 protrudes from the upper opening of the hole 101 and contacts the lower surface 231 of the limiting part 230. The lower surface 231 of the limiting part 230 is only subjected to the weight of the drawer cover 200 itself and the upward supporting force of the free end 122. The positional relationship between the body 100 and the drawer cover 200 is as follows. Figure 1 As shown, at this time, the drawer lid 200 and the body 100 form a small acute angle α. When the coffee capsule is installed on the support 110, the drawer is pushed into the cavity of the coffee machine. The upper edge 211 of the lid contacts the outer shell 500 of the coffee machine, especially the lower edge 501 of the outer shell. The drawer lid 200 is pushed by the lower edge 501 of the outer shell and begins to rotate around the pivot 221. The lower surface 231 of the limiting part 230 and the free end 122 begin to press against each other. The arm 121 begins to undergo elastic deformation and bend downward until the drawer is completely pushed into the cavity of the coffee machine. At this time, the lower edge 501 of the outer shell and the upper edge 211 of the lid are aligned vertically and there is an interaction force between them. The drawer lid 200 always has a tendency to rotate upward around the pivot 221.

[0028] In another embodiment, the positions of the free end 122 and the limiting part 230 can be interchanged. That is, the free end 122 and the arm 121 are located on the inner wall of the cover 210, and the limiting part 230 extends from the outer wall of the support 110. In this case, the lower surface of the limiting part 230 contacts the top end of the free end 122, and the lower surface 231 of the limiting part 230 is subjected to pressure from the free end 122, which comes from the weight of the drawer cover 200 itself. The vertical distance from the top end of the free end 122 to the arm 121 makes a small acute angle α between the drawer cover 200 and the body 100 (that is, a small acute angle α between the arm 121 and the lower surface 231 of the limiting part 230). When in the working state, the top end of the free end 122 is compressed, and the arm 121 bends downward to store elastic potential energy, which can also make the drawer cover 200 have an upward rotation tendency. Those skilled in the art can easily set it according to the solution of this utility model, so it is not shown in the figure and will not be described in detail.

[0029] When the coffee machine begins high-pressure brewing, the drawer experiences significant downward pressure, causing slight deformation and sinking to maintain a seal. However, because the drawer lid 200 always tends to rotate upwards around the pivot 221, even if the entire drawer sinks, the drawer lid 200 can compensate for the gap between itself and the outer casing 500 caused by the drawer sinking, especially the gap between itself and the lower edge 501 of the outer casing. This ensures that the upper edge 211 of the lid and the lower edge 501 of the outer casing remain in contact. Figure 4 As shown, it should be noted that Figure 4 The gap between the upper edge 211 of the cover and the lower edge 501 of the outer shell shown is to more clearly illustrate their positional relationship; in reality, there is no gap between them. Figure 3 and Figure 4 The free end 122 and the limiting part 230 shown are actually in a state of mutual compression, rather than being penetrated and penetrated.

[0030] In some coffee machines, the lower edge 212 of the lid contacts the outer casing 500 below it but does not compress it; in one embodiment, the lower edge 212 of the lid is suspended, in which case the lower edge 212 of the lid can act as a handle for pulling out the drawer. After the coffee machine finishes working, the user pulls the lower edge 212 of the lid, and with the assistance of the free end 122, the drawer lid 200 moves outward and rotates upward, the body 100 is released from the positioning mechanism inside the cavity, and the drawer can be easily pulled out. In other embodiments, a handle is provided on the outer wall of the lid 210, so the drawer can also be easily pulled out by directly pulling the handle.

[0031] In one embodiment, the platform 120 extends along the outer surface of the cover 210 in a horizontal direction. There is one or more holes 101 and one or more arms 121. The holes 101 and arms 121 do not necessarily correspond one-to-one. For example, in one embodiment, the hole 101 is an elongated hole, and several arms 121 are distributed within the hole 101 along its length. These arms can be evenly distributed or symmetrically distributed on both sides of the drawer's central axis, ensuring that the drawer cover 200 receives a uniform upward force during operation. In another embodiment, the number of holes 101 and arms 121 is the same, with one arm 121 provided within each hole 101, and each arm 121 corresponding to a free end 122.

[0032] In another embodiment, platform 120 is degraded and disappears (and hole 101 is not required), and arm 121 is formed by extending directly outward from the outer wall of support 110, with the same distribution as in the aforementioned embodiment.

[0033] In one embodiment, when the number of arms 121 is two or more, the lower surface 231 of the limiting portion 230 can completely cover / correspond to its corresponding free end 122. For example... Figure 5 and Figure 6 As shown, the arms 121 have five evenly distributed members, and the maximum width of the corresponding limiting portion 230 should not be less than the distance between the first arm 121 / free end 122 and the fifth arm 121 / free end 122. Furthermore, the limiting portion 230 can be as follows: Figure 5 and Figure 6 The continuous limiting plate shown can also be an intermittent limiting protrusion, as long as the lower surface of the limiting protrusion can contact the corresponding free end 122 and stably generate an interaction force; similarly, multiple free ends 122 can be connected to each other in the horizontal plane, and multiple arms 121 (except for the free ends 122) are not connected, as long as the free ends 122 can contact the lower surface of the limiting part 230 and stably generate an interaction force.

[0034] In some embodiments, the free end 122 and the lower surface 231 of the limiting portion 230 have a positioning mechanism that cooperates with each other. For example, the lower surface 231 has a recess that cooperates with the end face of the free end 122.

[0035] In one embodiment, the body 100 and the drawer cover 200 are integrally formed, and the displacement compensation function of the drawer cover 200 can be realized by the cooperation of these two components through the pivot 221 and the connecting hole 131. In other embodiments, the displacement compensation function can also be realized by setting other rotation reset mechanisms between the body 100 and the drawer cover 200. For example, the body 100 and the drawer cover 200 can be connected to the two arms of a torsion spring, such as installing a torsion spring between the pivot 221 and the second connecting part 220, or installing a reset spring between the inner wall of the cover 210 and the support 110. Those skilled in the art can understand and implement this, and it will not be described in detail here. However, setting such a rotation reset mechanism separately will increase the manufacturing and assembly costs.
