Description

Technical Field

[0001] This utility model relates to the field of coffee powder weighing technology for coffee machines, specifically to an adjustable weighing mechanism and its coffee machine. Background Technology

[0002] Most expensive coffee machines on the market today are equipped with electronic weighing systems. These systems are designed to help consumers better understand coffee preparation, especially beginners who can quickly master the appropriate coffee grounds weight for brewing a delicious cup. In coffee machines with weighing systems, the weighing components are typically fixed to the machine, requiring the coffee grounds dispenser to be placed in a fixed position to collect the grounds. A few machines feature removable weighing components, primarily for ease of cleaning. If coffee grounds spill onto the weighing component due to factors like flyaways or vibrations, reinstalling the weighing component often results in a fixed dispensing height, and the structure is not always robust enough, making it easy for the weighing component to loosen and leading to a poor user experience. Utility Model Content

[0003] This invention proposes an adjustable weighing mechanism and its coffee machine. The bracket and the fixed frame are adjusted in relative height via an adjustment mechanism, solving the problem of fixed assembly of existing weighing components resulting in a single powder receiving position. The weight sensor is fixedly connected to the fixed frame, which can accurately detect the weight of the material in the container to be weighed. The adjustment mechanism allows users to flexibly adjust the height of the bracket according to different container heights. Regardless of the height of the powder receiving container, the distance between the container opening and the powder dropper can be adjusted to a suitable level, effectively reducing powder scattering.

[0004] An adjustable weighing mechanism designed for this purpose includes: The bracket is used to hold the container to be weighed; A weighing assembly, comprising a weight sensor for detecting the volume of an object and a mounting bracket for supporting a fixed bracket, wherein the weight sensor is fixedly connected to the mounting bracket. The bracket is movably connected to the fixed frame, and an adjustment mechanism for adjusting the height of the bracket is provided between the bracket and the fixed frame.

[0005] The adjustment mechanism has a closed state and an open state; The bracket is clamped and thus relatively fixed on the fixed frame by the adjustment mechanism; When the adjustment mechanism is in the open state, the bracket can move up and down relative to the fixed frame and can separate the bracket from the fixed frame.

[0006] The bracket is equipped with an operating component for triggering the adjustment mechanism to switch from a closed state to an open state.

[0007] The operating component is disposed on the side of the bracket, and the side of the bracket is provided with mounting holes corresponding to the operating component; The mounting hole extends through the side of the bracket, and the main body of the operating component extends out of the bracket from the inside of the mounting hole, with the head of the operating component abutting against the inside of the mounting hole to form an anti-detachment structure that prevents the operating component from coming out of the bracket.

[0008] The adjustment mechanism includes a clamping element; The bracket is equipped with elastically rotating clamping components on both the left and right inner sides; The fixing frame is provided with several slots that cooperate with the clamping components; The bracket is fixed to the fixed frame, and the clamping member is provided with a positioning shaft that is fixed in one of the slots under elastic action.

[0009] Several of the card slots are arranged linearly along the height direction of the fixing frame.

[0010] The bracket has assembly slots on both the left and right inner sides for accommodating the clamping components, and a cover plate at the rear of the bracket for covering the opening of the assembly slots. The clamping component is equipped with a rotating shaft. The first end of the rotating shaft is rotatably connected to the cover plate, and the second end of the rotating shaft is rotatably connected to the inner side of the bracket assembly groove. The clamping components on the left and right sides of the bracket can switch the adjustment mechanism to a closed or open state by rotating.

[0011] The adjustment mechanism includes a spring that cooperates with the clamping element; The clamping member has a first connecting shaft at its first end and a second connecting shaft at its second end. Both the first connecting shaft and the second connecting shaft are provided with springs. The first end of the spring of the first connecting shaft abuts against the upper part of the clamping member, and the second end of the spring abuts against the upper part of the inner side of the bracket assembly groove; The first end of the spring of the second connecting shaft abuts against the lower part of the clamping member, and the second end of the spring abuts against the lower part of the inner side of the bracket assembly groove; The first connecting shaft and the second connecting shaft are vertically offset, the positioning shaft and the second connecting shaft are coaxially arranged, the first connecting shaft and the second connecting shaft extend into the clamping member, and the second connecting shaft extends outward from the clamping member; The bracket is provided with an operating member that acts on the clamping member. The operating member acts on the clamping member to drive the clamping member to rotate in the direction of the opening state of the adjustment mechanism. When the clamping parts on the left and right sides of the bracket rotate toward the open state of the adjustment mechanism, the springs of the first connecting shaft and the second connecting shaft are both in a compressed state; when the springs release their elastic force and the clamping parts rotate toward the closed state of the adjustment mechanism, the adjustment mechanism is elastically reset to the closed state.

[0012] The bracket is provided with a tray that extends laterally outward and is used to hold the container to be weighed; The fixing frame is located at the rear of the bracket, and the rear of the bracket is provided with a sliding groove that mates with the fixing frame. The fixing frame and the bracket are connected by the sliding groove to slide up and down relative to each other. The weighing assembly includes a bracket, which is disposed between the fixed frame and the weight sensor. The first side of the bracket is fixedly connected to the rear of the fixed frame, and the second side of the bracket is fixedly connected to the weight sensor. The lower part of the weight sensor is provided with a fixing component for fixing the weight sensor in conjunction with the fixing bracket and support.

[0013] A coffee machine includes a body with a grinding mechanism, a grinding chamber and a powder dispensing channel, wherein the body is provided with the aforementioned adjustable weighing mechanism; and the bracket is correspondingly arranged with the output end of the powder dispensing channel. The weighing component's mounting frame is fixedly mounted on the machine body, and the bracket's installation height on the mounting frame is adjusted by an adjustment mechanism; the bracket is switched to an open state by the adjustment mechanism so that the machine body's mounting frame and the bracket are separated.

[0014] The beneficial technical effects of this utility model are as follows: The bracket and the fixed frame are adjusted in relative vertical position via an adjustment mechanism, solving the problem of fixed assembly of existing weighing components resulting in a single powder receiving position. The weight sensor is fixedly connected to the fixed frame, which can accurately detect the weight of the material in the container to be weighed. The adjustment mechanism allows users to flexibly adjust the height of the bracket according to different container heights. Regardless of the powder receiving container of different heights, the distance between the container opening and the powder drop outlet can be adjusted to a suitable level, effectively reducing powder scattering.

[0015] The bracket and the fixed frame can be disassembled and assembled at different heights using a spring-loaded adjustment mechanism. This design retains the detachable and cleanable function of the bracket and frame; pressing the buttons on both sides of the bracket allows it to be removed from the fixed frame. Furthermore, the fixed frame features several vertically arranged slots, allowing the bracket to be locked into corresponding slots, enabling users to adjust the bracket to the desired height. This ensures that powder can be collected from containers of different sizes, meeting the needs of diverse users. In addition, this technical solution ensures stable and reliable assembly. After the bracket is assembled into the machine, its internal structure is firmly secured to the fixed frame, preventing it from falling off. The bracket can only be moved on the fixed frame by pressing the buttons on both sides of the bracket, which loosens the internal clamping mechanism and other transmission structures.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0026] See Figures 1-9 An adjustable weighing mechanism, comprising: Bracket 1, the bracket 1 being used to hold the container to be weighed; Weighing assembly 2, which includes a weight sensor 3 for detecting the volume of an object and a fixing frame 4 for supporting the fixing bracket 1, wherein the weight sensor 3 is fixedly connected to the fixing frame 4. The bracket 1 is movably connected to the fixed frame 4, and an adjustment mechanism 5 for adjusting the height of the bracket 1 is provided between the bracket 1 and the fixed frame 4.

[0027] The bracket 1 and the fixed frame 4 are adjusted in relative vertical position via the adjustment mechanism 5, solving the problem of a single powder receiving position caused by the fixed assembly of existing weighing components. The weight sensor 3 is fixedly connected to the fixed frame 4, which can accurately detect the weight of the material in the container to be weighed. The adjustment mechanism 5 allows users to flexibly adjust the height of the bracket 1 according to different container heights. Regardless of the powder receiving container of different heights, the distance between the container opening and the powder drop outlet can be adjusted to a suitable level, effectively reducing powder scattering.

[0028] The adjustment mechanism 5 has a closed state and an open state; The bracket 1 is clamped by the adjusting mechanism 5 and thus relatively fixed on the fixed frame 4; When the adjustment mechanism 5 is in the open state, the bracket 1 can move up and down relative to the fixed frame 4 and can separate the bracket 1 from the fixed frame 4.

[0029] When closed, bracket 1 is clamped and fixed to the fixed frame 4 by the adjusting mechanism 5, ensuring that bracket 1 will not wobble during weighing. When the adjusting mechanism 5 is open, bracket 1 can move up and down relative to the fixed frame 4 to meet different height adjustment needs, and the two can be separated, making it convenient for users to thoroughly clean bracket 1 and fixed frame 4. This solves the defect of existing detachable weighing components that are only designed for cleaning but have a fixed position after installation. The design of the adjusting mechanism 5, which has both closed and open states, ensures structural stability during use and prevents loosening, while also taking into account the convenience of cleaning and height adjustment function, thus improving the user experience.

[0030] The bracket 1 is equipped with an operating component 6 for triggering the adjustment mechanism 5 to switch from a closed state to an open state.

[0031] The operating component 6 is disposed on the side of the bracket 1, and the side of the bracket 1 is provided with a mounting hole 101 corresponding to the operating component 6; The mounting hole 101 passes through the side of the bracket 1, and the main body 602 of the operating member 6 extends out of the bracket 1 from the inside of the mounting hole 101, and the head 601 of the operating member 6 abuts against the inside of the mounting hole 101 to form an anti-detachment structure that prevents the operating member 6 from falling out of the bracket 1.

[0032] The operating component 6 is located on the side of the bracket 1, allowing users to easily trigger the adjustment mechanism 5 to switch from the closed to the open state, greatly simplifying the operation process. Users do not need additional tools; they can conveniently control the state of the adjustment mechanism 5 simply through the operating component 6. This reduces the operational difficulty for novice users, allowing them to quickly learn how to use it. The design of the operating component 6 makes the state switching process intuitive and effortless. Integrating the operating component 6 into the side of the bracket 1 does not affect the load-bearing function of the bracket 1, nor does it occupy extra space, making the overall structure more compact.

[0033] The adjustment mechanism 5 includes a clamping member 501; The bracket 1 is provided with elastically rotating clamping members 501 on both the left and right inner sides; The fixing frame 4 is provided with a plurality of slots 401 that cooperate with the clamping member 501; The bracket 1 is fixed relative to the fixed frame 4, and the clamping member 501 is provided with a positioning shaft 5014 that is fixed in one of the slots 401 under elastic action; Several of the card slots 401 are arranged linearly along the height direction of the fixing frame 4.

[0034] The elastically rotating clamping member 501, when closed, can tightly engage with the slot 401, ensuring the secure connection between the bracket 1 and the fixed frame 4 and preventing loosening during use. The multiple slots 401 provide multiple fixing positions for the bracket 1, allowing users to select the appropriate slot 401 according to their needs, achieving multi-level height adjustment to meet the requirements of containers of different heights. The clamping members 501 on both the left and right sides work simultaneously to balance the force on the bracket 1, ensuring its fixation to the fixed frame 4. Several slots 401 are linearly arranged along the height direction of the fixing frame 4, providing a continuous and regular selection of height adjustment levels for the bracket 1. This linear arrangement allows users to intuitively determine the required adjustment position based on the container height, making the adjustment process more systematic and facilitating quick and easy finding of the appropriate height. This arrangement makes the height adjustment levels more rationally distributed, covering a wider range of possible container heights. Regardless of the size difference between containers, a matching slot 401 can be found for fixation. Simultaneously, the linear arrangement structure allows for smoother up-and-down movement of the bracket 1, preventing adjustment obstruction due to cluttered slot positions. This ensures the stable operation of the adjustment mechanism 5, improves the efficiency and accuracy of user adjustment operations, and allows users to more easily complete height settings during use.

[0035] The bracket 1 has an assembly groove 103 on both the left and right inner sides for accommodating the clamping component 501, and a cover plate 7 at the rear of the bracket 1 for covering the opening of the assembly groove 103. The clamping member 501 is provided with a rotating shaft 5011. The first end of the rotating shaft 5011 is rotatably connected to the cover plate 7, and the second end of the rotating shaft 5011 is rotatably connected to the inner side of the mounting groove 103 of the bracket 1. The clamping members 501 on the left and right sides of the bracket 1 can switch the adjustment mechanism 5 to a closed state or an open state by rotating.

[0036] The mounting slots 103 on the left and right inner sides of the bracket 1 provide a stable installation space for the clamping component 501. The cover plate 7 covers the opening of the mounting slot 103, effectively cooperating with the bracket 1 to install the rotating clamping component 501 and ensuring its elastic rotation performance. The two ends of the rotating shaft 5011 of the clamping component 501 are rotatably connected to the cover plate 7 and the inner side of the mounting slot 103, respectively. This double-end rotation and fixing method makes the rotation of the clamping component 501 more stable. The left and right clamping components 501 switch the state of the adjustment mechanism 5 by rotation.

[0037] The adjustment mechanism 5 includes a spring 502 that cooperates with the clamping member 501; The clamping member 501 has a first connecting shaft 5012 at its first end and a second connecting shaft 5013 at its second end. Both the first connecting shaft 5012 and the second connecting shaft 5013 are provided with springs 502. The first end of the spring 502 of the first connecting shaft 5012 abuts against the upper part of the clamping member 501, and the second end of the spring 502 abuts against the upper part of the inner side of the mounting groove 103 of the bracket 1. The first end of the spring 502 of the second connecting shaft 5013 abuts against the lower part of the clamping member 501, and the second end of the spring 502 abuts against the lower part of the inner side of the mounting groove 103 of the bracket 1. The first connecting shaft 5012 and the second connecting shaft 5013 are vertically offset, the positioning shaft 5014 and the second connecting shaft 5013 are coaxially arranged, the first connecting shaft 5012 and the second connecting shaft 5013 extend into the clamping member 501, and the second connecting shaft 5013 extends outward from the clamping member 501. The bracket 1 is provided with an operating member 6 that acts on the clamping member 501. The operating member 6 acts on the clamping member 501 to drive the clamping member 501 to rotate in the direction of the opening state of the adjusting mechanism 5. When the clamping members 501 on the left and right sides of the bracket 1 rotate toward the open state of the adjustment mechanism 5, the springs 502 of the first connecting shaft 5012 and the second connecting shaft 5013 are both in a compressed state; when the springs 502 release their elastic force and cause the clamping members 501 to rotate toward the closed state of the adjustment mechanism 5, the adjustment mechanism 5 is elastically reset to the closed state.

[0038] The spring 502 in the adjusting mechanism 5 cooperates with the clamping member 501 to provide the adjusting mechanism 5 with an elastic reset function. When the spring 502 on the first connecting shaft 5012 at the first end and the second connecting shaft 5013 at the second end of the clamping member 501 is in a compressed state, it provides elastic potential energy to the clamping member 501. When the external force is removed, the spring 502 releases its elastic force to drive the clamping member 501 to rotate toward the closed state, realizing automatic reset without the need for manual adjustment by the user, thus simplifying the operation. This elastic reset design ensures that the clamping member 501 can be tightly engaged in the slot 401 through elastic force when in the closed state, enhancing the connection's firmness and preventing the bracket 1 from accidentally loosening during use. The elastic effect of the spring 502 makes the fit between the clamping member 501 and the slot 401 tighter. During the adjustment process, the user only needs to squeeze the spring 502 to switch states.

[0039] The bracket 1 and the fixed frame 4 can be disassembled and assembled at different heights through the adjustment mechanism 5 with spring 502. On the one hand, it retains the function of detachable cleaning between the bracket 1 and the fixed frame 4. When in use, the bracket 1 can be removed by pressing the operating parts 6 (buttons) on both sides of the bracket 1 and being locked on the fixed frame 4. On the other hand, by providing several vertically arranged slots 401 on the fixed frame 4, the bracket 1 can be locked in the corresponding slots 401, allowing the user to adjust the bracket 1 to the required height, so that containers of different cup sizes can be used to collect powder, meeting the needs of different users. In addition, this technical solution also has the advantages of stable and reliable assembly. After the bracket 1 is assembled into the whole machine, the internal structure of the bracket 1 will be tightly locked on the fixed frame 4, so there will be no falling off. The bracket 1 can only be moved on the fixed frame 4 by pressing the buttons on both sides of the bracket 1, which will drive the internal clamping parts 501 and other transmission structures to release the slots 401.

[0040] The bracket 1 is provided with a tray 102 that extends laterally outward and is used to hold the container to be weighed; The fixing frame 4 is located at the rear of the bracket 1. The rear of the bracket 1 is provided with a sliding groove 104 that cooperates with the fixing frame 4. The fixing frame 4 and the bracket 1 are connected by the sliding groove 104 to form a relative vertical sliding connection. The weighing component 2 includes a bracket 8, which is disposed between the fixed frame 4 and the weight sensor 3. The first side of the bracket 8 is fixedly connected to the rear of the fixed frame 4, and the second side of the bracket 8 is fixedly connected to the weight sensor 3. The lower part of the weight sensor 3 is provided with a fixing part 9 for fixing the weight sensor 3 in conjunction with the fixing frame 4 and the bracket 8.

[0041] The tray 102 on the bracket 1 extends laterally outward, increasing the area for holding the container to be weighed, thus ensuring stable placement of the container and preventing it from tipping over. The fixing frame 4 is located at the rear of the bracket 1 and is slidably connected to the bracket 1 via a sliding groove 104, making the vertical adjustment of the bracket 1 smoother, reducing frictional resistance, and improving the ease of adjustment. The bracket 8 is positioned between the fixing frame 4 and the weight sensor 3, enhancing the stability of the connection between the fixing frame 4 and the weight sensor 3.

[0042] Specifically: When the user presses the operating parts 6 (buttons) on both sides of the bracket 1, the connecting shaft rotates clockwise, and the positioning shaft 5014 on the lower side of the clamping part 501 leaves the slot 401 of the fixing frame 4. At this time, the bracket 1 can be moved up and down to the required height. When the button is released, the clamping part 501 is subjected to the force of the reset spring, and the connecting shaft rotates counterclockwise back to its original position to re-lock the slot 401 of the fixing frame 4, so that the adjusted bracket 1 is fixed.

[0043] A coffee machine includes a body with a grinding mechanism, a grinding chamber and a powder dispensing channel, wherein the body is provided with the aforementioned adjustable weighing mechanism; and the bracket 1 is correspondingly arranged with the output end of the powder dispensing channel. The mounting frame 4 of the weighing component 2 is fixedly mounted on the machine body. The bracket 1 is adjusted in height on the mounting frame 4 by means of the adjustment mechanism 5. The bracket 1 is switched to the open state by means of the adjustment mechanism 5 so that the mounting frame 4 of the machine body is separated from the bracket 1.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
