A coffee brewing component

Abstract

This invention relates to a coffee brewing assembly, comprising a lower support, an upper support, a handle, and a first locking lever. The assembly is characterized by further comprising a movable member disposed on the upper support and located on one side of the first locking lever, arranged to move relative to the upper support in a left-right direction toward or away from the first locking lever. This movable member has two states: in a first state, the movable member is located below the first locking lever and abuts against its corresponding position, keeping the handle in a locked, upward-swinging state; in a second state, the movable member is located beside the first locking lever to release the locking of the handle. Interference with the locking mechanism is effectively avoided only when the first locking lever is in the unlocked state. When the upper and lower supports need to be installed together, it is only necessary to release the locking of the handle and press down on the front end of the handle to engage the locking part with the first stop part, making the entire process convenient.

Description

Technical Field

[0001] This invention belongs to the field of coffee machine technology and relates to a coffee brewing component. Background Technology

[0002] Coffee machines are now an indispensable appliance in office spaces and home routines.

[0003] Coffee machines typically have brewing components. For example, the applicant's earlier Chinese utility model patent application, "A Brewing Device for an Open-Top Capsule Coffee Machine," patent number ZL202221721237.5 (authorization announcement number CN217937910U), discloses a brewing device for an open-top capsule coffee machine, including a lower brewing support with an open upper end; a coffee hopper assembly, which is removed or placed into the lower brewing support along its axial direction relative to the upper opening of the lower brewing support; and an upper brewing support, disposed on the lower brewing support. The upper brewing support is located above the lower brewing support, with one end rotatably connected to it. A brewing head assembly is located at the end of the upper brewing support near the lower brewing support. A drive mechanism is used to drive the upper brewing support to rotate relative to the lower brewing support, thereby enabling the brewing head assembly to move away from or closer to the coffee bag assembly. The drive mechanism is located at the end of the upper brewing support away from the lower brewing support, with one end rotatably connected to it. The drive mechanism includes a drive handle connected to the upper brewing support and a linkage mechanism connected between the drive handle and the upper brewing support.

[0004] When the aforementioned wrench is rotated downwards to a horizontal position, the second fixed shaft restricts the first hook from moving downwards, and the first fixed shaft restricts the first locking part from moving downwards, thus preventing the first locking part from locking onto the first fixed shaft, which in turn prevents the upper brewing bracket from moving downwards to a horizontal position normally. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a coffee brewing assembly that avoids interference with the downward movement of the upper support by locking the handle, in view of the current state of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a coffee brewing component, comprising:

[0007] The lower support is arranged along the front-back direction, and a receiving component for holding coffee is installed near the front side of the lower support, and a first stop is provided on the lower support.

[0008] An upper support is disposed above the lower support and arranged along the front and back. The rear side of the upper support is rotatably disposed on the lower support, and a brewing head for brewing coffee is installed on the upper support at the position corresponding to the receiving component.

[0009] A handle is arranged along the front-to-back direction, the rear end of which is rotatably mounted on the upper bracket, and the axis of rotation extends along the left-to-right direction so that the front end of the handle swings up and down relative to the upper bracket.

[0010] A first locking rod has a first end connected to the handle and a second end having a locking portion. The first locking rod is configured to swing back and forth along a rotation axis extending in the left-right direction under the action of the handle, and the rotation axis of the first locking rod is located in front of or behind the rotation axis of the handle. Thus, when the front end of the handle is in a downward swing state, the locking portion moves toward the first stop portion to a locked state with the first stop portion; or when the front end of the handle is in an upward swing state, the locking portion moves away from the first stop portion to disengage from the locked state with the first stop portion.

[0011] Its characteristic is that it further includes:

[0012] A movable component, disposed on the upper bracket and located on one side of the left and right sides of the first locking bar, is arranged to move relative to the upper bracket in a left-right direction toward or away from the first locking bar. The movable component has two states: in the first state, the movable component is located below the first locking bar and abuts against the corresponding position of the first locking bar, so that the handle is always kept in an upward-swinging locked state; in the second state, the movable component is located beside the first locking bar to release the locking state of the handle.

[0013] To ensure the movable component is in the first state, an elastic element is included to ensure that the movable component always tends to move in the direction of the first locking lever. This elastic element acts on the movable component. Thus, under the elastic recovery of the elastic element, the movable component moves in the direction of the first locking lever until it abuts against the first locking lever.

[0014] To achieve the second state of the movable component, a linkage component is also included to move the movable component away from the first locking rod to the second state. An action component is provided on the top surface of the lower bracket. The power input end of the linkage component is driven and connected to the action component, and the power output end of the linkage component is driven and connected to the movable component.

[0015] The movable component can move to its second state without a power source. The bottom surface of the movable component has a first inclined surface that gradually slopes upwards towards the first locking rod. The linkage component has a second inclined surface that matches the first inclined surface. The actuating component is an upwardly extending top portion. The linkage component corresponds to the top portion. When the upper bracket moves downwards to rest on the lower bracket, the top portion pushes the linkage component upwards relative to the upper bracket, causing the movable component to be in its second state. Thus, during the downward movement of the upper bracket, the top portion on the upper bracket continuously presses against the linkage component, unlocking the movable component through the cooperation of the first and second inclined surfaces.

[0016] Preferably, the linkage has an upwardly extending extension rod, and the movable member has an extension hole at the position corresponding to the extension rod, extending along the movement direction of the movable member, with the extension rod located within the extension hole. Alternatively, the linkage may have an extension hole, and the movable member may have an extension rod that slides within the extension hole.

[0017] Preferably, the upper bracket is provided with a fixing member, the fixing member having an end cap on the side of the movable member away from the first locking rod, the elastic member being a spring located between the end cap and the movable member, and the fixing member having a through hole at the position corresponding to the extension rod for the upper end of the extension rod to pass through. Alternatively, the elastic member can also be in the form of a spring sheet, and the cooperation between the through hole and the extension rod enables the linkage to move only up and down.

[0018] Preferably, the upper support has a cavity inside, and the linkage, the first locking rod and the movable member are all located in the cavity. The bottom wall of the cavity has a first opening at the position corresponding to the top part, which allows the top part to pass through.

[0019] Specifically, the lower support is provided with a support that extends upward into the cavity, the first stop part is a first limiting post provided on the support and extending in the left-right direction, the first limiting post is located behind the first end of the first locking rod, and the locking part is a first hook part formed on the first locking rod with the opening facing backward.

[0020] In order to enable the rotation of the first locking bar via the handle, a first rocker plate is also included, which is arranged in the front-back direction. The front end of the first rocker plate is fixedly connected to the rear end of the handle, and the position of the first rocker plate near the middle is rotatably connected to the corresponding position of the upper bracket. The rotation axis of the first rocker plate is located in front of the rotation axis of the handle and extends in the left-right direction. The rotation axis of the first rocker plate is the rotation axis of the first locking bar. The first end of the first locking bar is fixedly connected to the position of the first rocker plate away from the front end.

[0021] To achieve two-stage locking of the upper and lower supports, a connecting rod, a second rocker plate, and a second locking rod are also included. The second locking rod is located in front of the first locking rod. The first end of the connecting rod is rotatably connected to the first end of the second rocker plate. The second rocker plate is rotatably constrained on the upper support near its center. The first end of the second locking rod is relatively fixedly connected to the second rocker plate away from its first end. The lower support is provided with a second stop portion. The second end of the second locking rod has a locking portion that can lock with the second stop portion. The second stop portion is located on the movement path of the locking portion.

[0022] To ensure the stability of the installation of the upper and lower supports, the first locking rod is provided on both the left and right sides of the first rocker, and the second locking rod is provided on both the left and right sides of the second rocker.

[0023] Compared with the prior art, the advantages of this invention are as follows: In this coffee brewing assembly, the locking and unlocking of the handle is achieved by the left and right movement of the movable part. When the handle is locked, the movable part presses against the first locking rod. At this time, the first locking rod and the handle are always in an upward swing state, while the locking part is away from the first stop part and is in an unlocked state. When the front end of the upper bracket rotates relative to the lower bracket, the first stop part will not interfere with the locking part. That is, interference with the locking part can be effectively avoided only when the first locking rod is in the unlocked state. When it is necessary to install the upper and lower brackets together, it is only necessary to release the lock on the handle and press down on the front end of the handle to lock the locking part with the first stop part. The whole process is convenient to operate. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 8 As shown, the coffee brewing assembly of this embodiment includes a lower support 1, an upper support 2, a handle 3, a first locking rod 4, a movable component 5, a linkage component 6, an elastic component, a fixing component 22, a first rocker 81, a connecting rod 82, a second rocker 83, and a second locking rod 9. The lower support 1 is arranged along the front-rear direction, and a coffee-containing component 11 is installed near its front side. A first stop portion is provided on the lower support 1. The upper support 2 is located above the lower support 1 and is arranged along the front-rear direction. The rear side of the upper support 2 is rotatably mounted on the lower support 1, and a brewing head 21 for brewing coffee is installed on the upper support 2 at a position corresponding to the coffee-containing component 11. In this embodiment, an upwardly extending mounting base 10 is provided at the rear of the lower support 1, and the rear side of the upper support 2 is mounted on the mounting base 10 via a mounting shaft.

[0034] The upper support 2 described above has a cavity 20 inside, and the movable member 5, elastic member, fixing member 22, first rocker 81, connecting rod 82, second rocker 83, first locking rod 4, and second locking rod 9 are all located within the aforementioned cavity 20. For the specific orientation of this embodiment, please refer to [reference needed]. Figure 1 and Figure 7 The direction indicated by the middle arrow.

[0035] The handle 3 is arranged along the front-to-back direction, and the rear end of the handle 3 is rotatably mounted on the upper bracket 2. The rotation axis of the handle 3 extends along the left-to-right direction, so that the front end of the handle 3 swings up and down relative to the upper bracket 2. The first rocker 81 is provided with a first locking rod 4 on both the left and right sides. The two first locking rods 4 are connected to the first rocker 81 in the same way. The following description uses one of the first locking rods 4 as an example.

[0036] like Figure 2 , Figure 5 , Figure 7 and Figure 8As shown, the first end of the first locking rod 4 is connected to the handle 3 via the first rocker plate 81, and the second end of the first locking rod 4 has a locking part. The first locking rod 4 is arranged to swing back and forth under the action of the handle 3, and the rotation axis of the first locking rod 4 is located in front of or behind the rotation axis of the handle 3. Thus, when the front end of the handle 3 is in a downward swing state, the locking part moves towards the first stop part to lock with the first stop part; or when the front end of the handle 3 is in an upward swing state, the locking part moves away from the first stop part to disengage from the first stop part. In this embodiment, a support 12 is provided on the lower bracket 1, which extends upward into the chamber 20. The first stop part is a first limiting post 121 provided on the support 12 and extending in the left-right direction. In this embodiment, the rotation axis of the first locking rod 4 is located in front of the rotation axis of the handle 3, the first limiting post 121 is located behind the first end of the first locking rod 4, and the locking part is a first hook part 41 formed on the first locking rod 4 with an opening facing backward.

[0037] The aforementioned first rocker arm 81 is arranged along the front-to-back direction. The front end of the first rocker arm 81 is fixedly connected to the rear end of the handle 3, and the position of the first rocker arm 81 near the middle is rotatably connected to the corresponding position of the upper bracket 2. The rotation axis of the first rocker arm 81 extends along the left-to-right direction, and the first end of the first locking rod 4 is fixedly connected to the position of the first rocker arm 81 away from the front end. The rotation axis of the first rocker arm 81 is the same as the rotation axis of the first locking rod 4.

[0038] The movable component 5 is mounted on the upper bracket 2 and located on one side of the left and right sides of the first locking rod 4. It is arranged to move relative to the upper bracket 2 in a left-right direction towards or away from the first locking rod 4. The movable component 5 then has the following two states: In the first state, as... Figure 3 and Figure 4 As shown, the movable part 5 is located below the first locking rod 4 and abuts against the corresponding position of the first locking rod 4, so that the handle 3 always remains in the upward-swinging locked state; in the second state, as Figure 7 and Figure 8 As shown, the movable member 5 is located beside the first locking rod 4 to release the locking state of the handle 3. In this embodiment, the elastic member acts on the movable member 5, causing the movable member 5 to always have a tendency to move in the direction of the first locking rod 4. Specifically, the movable member 5 is located on the right side of the first locking rod 4, and a fixing member 22 is provided on the upper bracket 2. The fixing member 22 has an end cap 221 on the side of the movable member 5 away from the first locking rod 4. The end cap 221 is located on the right side of the movable member 5, and the elastic member is a spring 7 located between the end cap 221 and the movable member 5.

[0039] The linkage 6 is used to move the movable part 5 away from the first locking rod 4. An actuating element is provided on the top surface of the lower bracket 1. The power input end of the linkage 6 is driven and connected to the actuating element, and the power output end of the linkage 6 is driven and connected to the movable part 5. Specifically, the linkage 6 is located to the right of the first locking rod 4. Figure 4 and Figure 8 As shown, the bottom surface of the movable member 5 has a first inclined surface 51 that gradually slopes upward toward the first locking rod 4, and the linkage member 6 has a second inclined surface 61 that matches the first inclined surface 51. Furthermore, the linkage member 6 has an upwardly extending extension rod 62, and the movable member 5 has an extension hole 52 extending along the movement direction of the movable member 5 at the position corresponding to the extension rod 62, with the extension rod 62 located within the extension hole 52. The aforementioned fixing member 22 has a through hole 222 at the position corresponding to the extension rod 62, through which the upper end of the extension rod 62 passes. The aforementioned actuating member is an upwardly extending top portion 13, and the linkage member 6 corresponds to the top portion 13. When the upper support 2 moves downward to rest on the lower support 1, the top portion 13 pushes the linkage member 6 upward relative to the upper support 2, causing the movable member 5 to be in the second state. Specifically, the bottom wall of the chamber 20 has a first opening 201 at the position corresponding to the actuating member 13, through which the actuating member 13 passes.

[0040] like Figure 5 As shown, second locking rods 9 are provided on both the left and right sides of the second rocker 83. The two second locking rods 9 are connected to the second rocker 83 in the same way; the following explanation uses one of the second locking rods 9 as an example. The aforementioned second locking rod 9 is located in front of the first locking rod 4. The first end of the connecting rod 82 is rotatably connected to the first end of the second rocker 83. The second rocker 83 is rotatably constrained to the upper bracket 2 near its center. The first end of the second locking rod 9 is relatively fixedly connected to the position of the second rocker 83 away from its first end. A second stop portion is provided on the lower bracket 1. The second end of the second locking rod 9 has a locking portion that can lock with the second stop portion. The second stop portion is located on the movement path of the locking portion. In this embodiment, Figure 2 and Figure 6 As shown, the locking part is a second hook 91 with its opening facing rearward, and the second stop part is a second limiting post 14 that is provided on the lower bracket 1 and extends in the left-right direction. The bottom wall of the chamber 20 has a second opening 202 at the position corresponding to the second locking rod 9, through which the second hook 91 of the second locking rod 9 passes.

[0041] For details on the locking of the first hook on the first locking rod with the first limiting post, and the locking of the second hook on the second locking rod with the second limiting post, please refer to the prior art referenced in the background art; these details will not be elaborated upon in this embodiment.

[0042] The working process of the above coffee brewing components is as follows:

[0043] Pulling the front end of the handle 3 upwards causes the first hook 41 of the first locking rod 4 to disengage from the first limiting post 121 via the first rocker 81. Simultaneously, the first rocker 81, connecting rod 82, and second rocker 83 cause the second hook 91 of the second locking rod 9 to disengage from the second limiting post 14. At this point, both the first locking rod 4 and the second locking rod 9 are in the unlocked state. Subsequently, pulling the front end of the bracket 2 upwards causes the bottom surface of the linkage 6 to continuously disengage from the top part 13. With the cooperation of the first inclined surface 51 and the second inclined surface 61, and under the action of the spring 7, the movable part 5 continuously moves towards the first locking rod 4. When the movable part 5 presses against the first locking rod 4, the handle 3 remains in the upward-swinging locked state.

[0044] Pressing down the front end of the upper bracket 2, when the front end of the upper bracket 2 rests on the lower bracket, the top part 13 continuously pushes the linkage 6. With the cooperation of the first inclined surface 51 and the second inclined surface 61, it drives the movable part 5 to move away from the first locking rod 4 until the movable part 5 disengages from the first locking rod 4. At this time, the handle 3 is in the unlocked state. Pressing down the front end of the handle 3, the handle 3 drives the first hook part 41 of the first locking rod 4 to hook onto the first limiting post 121 through the first rocker plate 81, and drives the second hook part 91 of the second locking rod 9 to hook onto the second limiting post 14 through the first rocker plate 81, the connecting rod 82 and the second rocker plate 83. At this time, the installation of the upper and lower brackets of the coffee brewing assembly is realized.

[0045] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings.
