[0056] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0059] See also Figures 1 to 15 The utility model provides a liquid weighing device, which is mainly used in beverage preparation equipment, and is structurally applicable to beverage preparation equipment of various specifications and purposes, and can be used to weigh the weight of the liquid in the beverage preparation equipment as needed.

[0060] In view of this, the present invention also provides a beverage preparation device. The specific form of the beverage preparation device is not limited, such as a common coffee machine, soybean milk machine, food processor, etc. The beverage preparation device can be integrated with required functions according to actual needs, such as integrated grinding, brewing, heating, cooling and other functions.

[0061] The beverage preparation device comprises a body and a liquid weighing device.

[0062] The machine body includes a housing, and the housing defines a beverage outlet. The beverage outlet is generally arranged downward, and can be used to discharge the beverage prepared in the beverage preparation device. The housing is generally also provided with a receiving platform 300 below the beverage outlet. The receiving platform 300 is at least used to support containers such as cups, bottles, bowls, cans, etc. The container is used to hold the beverage discharged from the beverage outlet.

[0063] The receiving platform 300 can be defined by a combination of a box body and a grid plate according to actual needs. The box body can be a water collection box, a slag collection box, etc., without limitation. The grid plate can be used to filter solid slag and can also be used to stably place the container.

[0064] Since the main invention of the utility model is to improve the liquid weighing device, the following will be combined with the attached Figures 1 to 15 , mainly describes the structure of the liquid weighing device.

[0065] It should be noted that, since the receiving table 300 of the beverage preparation device is generally arranged upward, in the following embodiments, the liquid weighing device is described as having a vertical direction and a horizontal plane substantially perpendicular to the vertical direction. The horizontal plane has a first direction and a second direction arranged crosswise (for example, 90 degrees).

[0066] In the present design, the liquid weighing device includes a main body component 100, which is adapted to be placed on the receiving platform 300 of the beverage preparation equipment, and includes a weighing device 120 and a tray 130. The weighing device 120 includes a fixed portion 121 fixed relative to the receiving platform 300, and a weighing portion 122 suspended relative to the receiving platform 300; the tray 130 is suspended from the receiving platform 300, and the tray 130 abuts against the weighing portion 122 at least when receiving the liquid, so that the weighing portion 122 can measure the weight of the liquid.

[0067] In the technical solution provided by the present invention, the fixing portion 121 of the weighing device 120 is fixed relative to the receiving platform 300, which facilitates the structural stability between the weighing device 120 and the receiving platform 300; the weighing portion 122 of the weighing device 120 is suspended relative to the receiving platform 300, so that when the tray 130 receives the liquid discharged through the beverage outlet of the beverage preparation equipment, the tray 130 abuts against the weighing portion 122. At this time, the weighing portion 122 is only subjected to force from the tray 130 and the liquid received therein, and will not be affected by other components such as the base 110, thereby achieving the purpose of weight measurement and helping to improve the accuracy of weight measurement.

[0068] It can be understood that the fixing part 121 in the weighing device 120 can be directly placed on the receiving platform 300, or indirectly placed on the receiving platform 300 through a fixing structure. When the fixing part 121 is placed on the receiving platform 300 through a fixing structure:

[0069] In one application, the fixed structure may include a base 110. The base 110 may be in a plate-like, block-like, or box-like shape. Taking the plate-like base 110 as an example, the base 110 is roughly spread out along a horizontal plane, and the shape of the bottom surface of the base 110 is roughly adapted to the shape of the table top of the receiving table 300 of the beverage preparation equipment. For example, when the table top of the receiving table 300 is roughly a flat surface, the bottom surface of the base 110 is also set to a flat surface; when the table top of the receiving table 300 is roughly a concave-convex surface, the bottom surface of the base 110 can also be set to a concave-convex surface, or set to a flat surface that can be stably supported on each protrusion of the concave-convex surface.

[0070] Please combine Figure 2 and Fig. 9In a specific embodiment, the main assembly 100 further includes a support pad 160, which is arranged on the side of the base 110 facing away from the weighing device 120, that is, arranged on the bottom surface of the base 110. The shape of the support pad 160 is not limited, for example, it can be set to a long strip, a sheet, etc. The number of support pads 160 is not limited, and when there are multiple support pads 160, each support pad 160 can be set at a designated area of ​​the bottom surface of the base 110 according to actual needs. The material of the support pad 160 can be a rigid material with a greater roughness, so as to increase the friction between the base 110 and the receiving platform 300, thereby preventing the main assembly 100 from moving relative to the receiving platform 300. The material of the support pad 160 can also be a flexible material, so that the base 110 and the receiving platform 300 can be flexibly abutted, and to a certain extent, the external force on the main assembly 100 can be buffered and damped. In addition, the support pad 160 has a certain thickness, so the base 110 can be raised, so that a certain distance is formed between the bottom surface of the base 110 and the table surface of the receiving platform 300, so that, for example, when there are stains remaining on the receiving platform 300, the liquid weighing device will not be contaminated.

[0071] The weighing device 120 and the tray 130 are both disposed on the base 110 and are approximately located above the base 110. Specifically, the weighing device 120 may be disposed above the tray 130, so that the tray 130 applies force to the weighing portion 122 in a suspended manner. Figures 1 to 9 In the illustrated embodiment, the weighing device 120 may be disposed below the tray 130 , so that the tray 130 applies force to the weighing portion 122 in a pressing manner.

[0072] When the weighing device 120 is arranged below the tray 130, that is, the weighing device 120 is located between the base 110 and the tray 130, specifically, in one embodiment, the fixing portion 121 is connected and fixed to the upper surface of the base 110, and the weighing portion 122 is suspended above the base 110; the tray 130 is supported at the upper end of the weighing portion 122, and the tray 130 at least covers the weighing device 120.

[0073] The fixing part 121 and the weighing part 122 are connected in sequence approximately along the first direction, so that the weighing device 120 as a whole is approximately a cantilever structure extending along the first direction. The fixing part 121 and the weighing part 122 can be integrally formed in structure, or can be detachably or non-detachably connected after being separately formed. A weight sensor device is preset at the weighing part 122, or the weight sensor device directly constitutes the weighing part 122.

[0074] In another application, the fixing structure may include a connecting member 140. The connecting member 140 corresponds to the connecting fixing portion 121, and its size may be set to be relatively smaller.

[0075] Of course, in another application, the fixing structure may include a base 110 and a connecting member 140 that are independently arranged from each other. In this case, the base 110 is placed on the receiving platform 300, and the connecting member 140 connects the base 110 and the fixing portion 121 respectively. Figure 2 , Figures 5 to 8 As shown, the connecting member 140 is fixedly connected to the base 110 by, for example, a third screw connection. The connecting member 140 can also be screwed and fixed to the base 110 and the fixing portion 121 simultaneously by the first screw connection 181; or the connecting member 140 is screwed and fixed to the fixing portion 121 by the first screw connection 181 alone, so as to achieve the purpose of installing the fixing portion 121 on the base 110.

[0076] The weighing part 122 and the tray 130 can be arranged to abut against each other when the tray 130 receives liquid, and to be separated and spaced a certain distance apart when the tray 130 does not receive liquid, so as to avoid the empty tray 130 interfering with the weighing part 122. Alternatively, the weighing part 122 and the tray 130 can remain connected, for example Figures 7 and 8 As shown, the weighing part 122 can be connected to the tray 130 from bottom to top through the second screw connection 182 .

[0077] It should be noted that, regardless of whether the tray 130 is loaded with liquid or not, the tray 130 is suspended relative to the base 100, that is, the tray 130 is basically not in direct contact with the base 100, so as to avoid the support force of the base 100 on the tray affecting the weight measurement accuracy of the liquid loaded on the tray 130 by the weighing unit 122. Figure 8 As shown, the weighing part 122 is suspended relative to the base 110, that is, a preset distance H2 needs to be spaced between the bottom surface of the weighing part 122 and the top surface of the base 110. When the weighing part 122 is screwed and fixed to the tray 130 by the second screw connector 182 as described above, a preset distance H1 also needs to be spaced between the bottom surface of the second screw connector 182 and the top surface of the base 110.

[0078] The tray 130 needs to cover at least the weighing device 120. It is understood that the tray 130 needs to cover the remaining surface of the weighing device 120 except the surface on one side facing the base 110, so that the weighing device 120 is basically not exposed above the tray 130. When the tray 130 directly receives the liquid, or receives the liquid through a supporting container, it is prevented that the liquid flows to and remains on the weighing device 120, especially on the weighing part 122, causing deviations in subsequent weighing results.

[0079] Furthermore, in one embodiment, the tray 130 is arranged to cover the upper surface of the base 110, and a convex bump 131a is formed on a partial plate surface of the tray 130, and the weighing device 120 is accommodated in the convex bump 131a. The tray 130 covers the entire upper surface of the base 110, and a relatively closed space can be formed between the tray 130 and the base 110, which helps to better accommodate the weighing device 120. At this time, the tray 130 is roughly in the shape of a cover shell, which is covered on the upper end of the base 110. In order to avoid a space suitable for accommodating the weighing device 120, a convex bump 131a is formed on a partial plate surface of the tray 130, and the convex bump 131a forms a concave portion at the bottom end of the tray 130, and the concave portion is covered on the upper end of the base 110 to form a space for accommodating the weighing device 120.

[0080] The forming position of the convex hump 131a can be adjusted arbitrarily according to actual needs, but generally, in order to make the center of gravity of the liquid weighing device as a whole stable, in one embodiment, the convex hump 131a is set at the center of the tray 130, or is set near the center of the tray 130 on the circumference.

[0081] In addition, the convex bump 131a can be directly integrally formed with the tray 130, for example, formed by stamping the plate material of the tray 130. Of course, the convex bump 131a can also be formed separately from the tray 130 and then connected detachably or non-detachably.

[0082] Furthermore, please combine Figure 3 to Figure 4 In one embodiment, the tray 130 and the base 110 are provided with through holes at corresponding positions. Specifically, the through hole at the base 110 is the first through hole 111, and the through hole at the tray 130 is the second through hole 131d. When the tray 130 covers the entire upper surface of the base 110, it can extend downward along the hole wall of the first through hole 111 to the bottom end of the base 110, thereby ensuring that the space defined between the base 110 and the tray 130 is more closed and less prone to water leakage. The provision of the first through hole 111 and the second through hole 131d can guide the accumulated water on the tray 130 to the supporting platform, especially when the supporting platform is provided as a water collecting box and a grid plate structure, the accumulated water on the tray 130 can be discharged in time.

[0083] Based on this, if the tray 130 is defined to include the first plate surface 131b forming the convex bump 131a and the remaining second plate surface 131c:

[0084] In one embodiment, at least a portion of the first plate surface 131b extends gradually downward in a direction close to the second plate surface 131c on the peripheral side. Figure 3As shown, the convex bump 131a is arranged adjacent to the second through hole 131d. In addition to a first plate surface 131b adjacent to the second through hole 131d, the convex bump 131a is also generally composed of three first plate surfaces 131b formed in one piece. The three first plate surfaces 131b are all arranged as inclined straight surfaces, and the inclination directions of the three first plate surfaces 131b are different. Of course, the inclined extension can be an inclined straight surface or a curved surface, without limitation. In this way, it is helpful to guide the accumulated water at the convex bump 131a to the second plate surface 131c along the inclined trend.

[0085] And / or in one embodiment, at least part of the second plate surface 131c extends gradually downwardly in a direction close to the through hole. Similarly to the above, the second plate surface 131c can be one piece or a plurality of pieces formed in one piece. At least one of the second plate surfaces 131c is subjected to the above-mentioned inclined extension. When at least two second plate surfaces 131c are subjected to the above-mentioned inclined extension, the inclined directions of the two second plate surfaces 131c can be the same or different. The inclined extension can be an inclined straight surface or a curved surface, without limitation. In this way, it helps to guide the accumulated water at the second plate surface 131c to the first through hole 111 and the second through hole 131d along the inclined trend, so as to avoid the formation of excessive water accumulation at the tray 130, which affects the accuracy of the weighing result.

[0086] Furthermore, please combine Figure 2 In one embodiment, a receiving groove 131 is formed at the upper end of the tray 130; the main assembly 100 further includes a grid member 150, which is installed at the notch of the receiving groove 131 and is used to support a container containing liquid. The grid member 150 is formed with a plurality of grid holes, which can facilitate the support of the container and prevent solid slag from entering the receiving groove 131.

[0087] There is no limitation on the connection method between the grid member 150 and the tray 130. Figures 1 to 4 As shown, an annular step may be provided protrudingly and surroundingly on the inner wall of the receiving groove 131 near the notch, and the grille member 150 is supported on the annular step. Further, a buckle portion 132 may be provided protrudingly on the side wall of the receiving groove 131 of the tray 130, and a buckle groove portion 151 may be formed by being recessed at a corresponding position of the grille member 150, and the buckle portion 132 and the buckle groove portion 151 are buckled and fixed, so that the grille member 150 is limited between the annular step and the buckle portion 132.

[0088] In addition, in one embodiment, the liquid weighing device further includes a display module, which is electrically connected to the weighing device 120 to display the measurement result of the weighing device 120. The display module can display any appropriate information according to actual needs, such as directly displaying the actual measurement data of the weighing device 120 in real time, displaying the associated data obtained by converting the actual measurement data, and displaying the status information of the weighing function of the weighing device 120. The display module can be set on the main assembly 100, or the display module can be set separately from the main assembly 100, such as being externally placed on the body.

[0089] Please combine Figures 5 to 8 In one embodiment, the liquid weighing device further comprises a mounting member 200, and the mounting member 200 is used to be connected and fixed to the shell plate 400 to be installed of the beverage preparation device. The shell 220 to be installed can be any shell plate of the shell in the beverage preparation device, such as the front panel of the shell. At this time, the mounting member 200 is, for example, specially provided with a mounting rib 210, and the mounting rib 210 is adapted to the shape of the shell 220 to be installed, for example, it can be closely attached to the outer side or inner side of the front panel. The mounting rib 210 is detachably connected to the shell plate 400 to be installed through a screw connection.

[0090] One end of the main assembly 100 is rotatably mounted on the mounting member 200, so as to drive the other end of the main assembly 100 to flip to a storage state close to the shell plate 400 to be installed, and flip to a use state away from the shell plate 400 to be installed. In this way, the main assembly 100 is switched between the storage state and the use state by rotating the main assembly 100 relative to the mounting member 200. The rotation process of the main assembly 100 can be directly realized by manual drive of the user, or a driving mechanism can be additionally provided in the liquid weighing device, and the driving mechanism realizes the intelligent and controllable rotation of the main assembly 100.

[0091] See also Figure 10 to Figure 11 In one embodiment, the upper surface of the receiving platform 300 can be directly set as a flat surface. When the main body component 100 is turned over to be in use, the main body component 100 is protruded and placed on the upper surface of the receiving platform 300.

[0092] Similarly, the side surface of the shell plate 400 facing the receiving platform 300 (for example, the front surface of the front panel) can be set as a flat surface. When the main assembly 100 is turned over to the storage state, the main assembly 100 protrudes against the side surface of the shell plate 400 to be installed.

[0093] Or see Figure 12 to Figure 13In one embodiment, the upper surface of the receiving platform 300 may be provided with a first recess. When the main body component 100 is flipped over to be in use, the main body component 100 is at least partially embedded in the first recess. Specifically, the shape and size of the first recess may be set to be roughly adapted to the main body component 100, so that the first recess can just accommodate the main body component 100. In this way, it helps to reduce the protruding height of the main body component 100 compared to the upper surface of the receiving platform 300, increase the aesthetics, and help reduce the mutual interference between the main body component 100 and the surrounding side, and help to roughly limit the main body component 100 in the circumferential direction with the help of the first recess.

[0094] Furthermore, when in the use state, the upper surface of the main assembly 100 may be substantially flush with the upper surface of the receiving platform 300. That is, the depth of the first recess is substantially matched with the thickness of the main assembly 100, and the protruding height of the main assembly 100 compared with the upper surface of the receiving platform 300 is fully eliminated.

[0095] Likewise, see Figure 14 to Figure 15 In one embodiment, a second recess is provided on a side surface of the shell plate 400 to be installed facing the receiving platform 300 (e.g., the front surface of the front panel). When the main body component 100 is flipped to be in the storage state, the main body component 100 can be configured to be at least partially embedded in the second recess of the shell plate 400 to be installed. Specifically, the shape and size of the second recess can be configured to be roughly adapted to the main body component 100, so that the second recess can just accommodate the main body component 100. In this way, it helps to reduce the protruding height of the main body component 100 compared to the surface of the shell plate 400 to be installed, and while increasing the aesthetics, it helps to reduce the mutual interference between the main body component 100 and the surrounding side, and helps to roughly limit the main body component 100 in the circumferential direction with the help of the second recess.

[0096] Furthermore, when in the storage state, the bottom surface of the main assembly 100 may be substantially flush with, for example, the front surface of the shell plate 400 to be installed. That is, the depth of the second recess is substantially matched with the thickness of the main assembly 100, and the protruding height of the main assembly 100 compared to the front surface of the shell plate 400 to be installed is fully eliminated.

[0097] In addition, regardless of whether the main body component 100 is embedded in the receiving platform 300 and / or embedded in the shell plate 400 to be installed, in a further solution, it can be set that when in the use state, the main body component 100 can slide relative to the upper end surface of the receiving platform 300 (or the concave bottom of the first concave portion), so that the placement position of the main body component 100 on the receiving platform 300 can be adjusted according to actual needs, which is more practical and universal. Similarly, it can be set that when in the storage state, the main body component 100 can slide relative to the front surface of the shell plate 400 to be installed (or the concave bottom of the second concave portion), so that the abutment position of the main body component 100 on the shell plate 400 to be installed can be adjusted according to actual needs, which is more practical and universal.

[0098] Furthermore, in one embodiment, the main assembly 100 is rotatably mounted on the mounting member 200 via a damping shaft. When an external force is applied, the damping shaft can realize the rotation of the main assembly 100 relative to the mounting member 200 to any angle; when the external force is removed, the damping shaft can realize the locking of the main assembly 100 at the current rotation angle.

[0099] And / or in one embodiment, one end of the main assembly 100 is connected to the connecting shaft 142, and the liquid weighing device further comprises at least two meshing gears, one of the gears is coaxially mounted with the connecting shaft 142, and the other of the gears is fixedly connected with the mounting member 200. Figure 5 As shown, in combination with the setting of the connecting member 140, the connecting member 140 can be provided with a rotation-stopping fitting hole 141 along the second direction, and the connecting shaft 142 is substantially a square shaft, which will not rotate relative to the connecting member 140 when inserted and installed with the rotation-stopping fitting hole 141. The mounting member 200 is provided as one or two, wherein one of the mounting members 200 includes two shells 220, and the two shells 220 are detachably connected and jointly enclose a mounting cavity 221 when connected. Each gear is accommodated in the mounting cavity 221, and includes a first gear 230, a second gear 240, and the remaining gears meshed between the first gear 230 and the second gear 240. The first gear 230 is coaxially connected and fixed to the connecting shaft 142, and the second gear 240 is coaxially connected to a fixed shaft provided on the shell 220. When the main assembly 100 rotates relative to the mounting member 200 under external force operation, the first gear 230 is driven to rotate and mesh with the second gear 240 in turn, ultimately achieving an adjustable and lockable rotation stroke of the main assembly 100 relative to the mounting member 200.

[0100] Furthermore, in one embodiment, the liquid weighing device further includes a stopper 170, and the stopper 170 is disposed on the main body assembly 100 and / or the shell to be installed 220, so that when the main body assembly 100 is flipped to the storage state, the stopper 170 connects and fixes the main body assembly 100 and the shell to be installed 220. The stopper 170 helps to strengthen the connection between the main body assembly 100 and the shell to be installed 220 when the main body assembly 100 is flipped to the storage state, and prevents the main body assembly 100 from flipping back and restoring to the use state, which affects the normal liquid discharge of the beverage outlet of the beverage preparation device.

[0101] Specifically, please combine Figure 4 In one embodiment, one of the shell to be installed 220 and the main assembly 100 is configured to be made of a metal material, the limiter 170 is provided at the other of the shell to be installed 220 and the main assembly 100, and the limiter 170 is made of a magnetic material. In this way, the main assembly 100 in the storage state can be limited in the shell to be installed 220 by the mutual magnetic adsorption of the magnetic material and the metal material. Taking the setting of the limiter 170 in the main assembly 100 as an example, the limiter 170 and the main assembly 100 can be detachably connected. The number of limiters 170 at the main assembly 100, the setting area, the magnetic attraction strength, etc. can all be specifically adjusted according to actual needs.
