Description

Technical Field

[0001] This utility model belongs to the technical field of coffee extraction equipment, specifically providing a water tank and coffee machine for a coffee machine. Background Technology

[0002] As a common beverage making device, the water tank of a coffee machine is one of the core components for ensuring a continuous water supply. The structure of the water tank lid directly affects the convenience of adding water, its sealing performance, and the user experience.

[0003] In existing technologies, the water tank lid of coffee machines typically uses a plug-in or rotating connection structure. Plug-in lids require complete removal to open, which is prone to loss and involves cumbersome procedures. Rotating lids, however, do not have this problem. Rotating lids are hinged to the body via a pivot, and rotate around this pivot when opened. However, during this rotation, the lid can easily interfere with the edges of the body or surrounding components, especially in coffee machines with a compact overall structure. This can limit the opening range of the lid, resulting in a smaller opening and making water refilling inconvenient. Utility Model Content

[0004] One objective of this invention is to solve the problem that the water tank of existing coffee machines with rotating lids has a small opening range when opened.

[0005] To achieve the above objectives, the present invention provides, in a first aspect, a water tank for a coffee machine, comprising: The box-shaped enclosure has an upward-facing opening; A connecting seat is provided on the inner side of the top of the housing, and the connecting seat is provided with a connecting shaft; A box lid includes a lid body and a connecting arm disposed inside the lid body. The connecting arm is provided with a strip-shaped hole. The box lid is rotatably slidably connected to the connecting shaft through the strip-shaped hole, so that the box lid can change from a posture of covering the opening to a posture of opening the opening by first moving upward and then rotating to one side of the box body.

[0006] Optionally, the connecting seat includes a seat body and a lug, the seat body is fixedly connected to the housing, the lug is disposed on the top side of the seat body, and the connecting shaft is disposed on the inner side of the lug.

[0007] Optionally, the connecting seat further includes a plurality of locking protrusions disposed on the bottom side of the seat body, the plurality of locking protrusions being distributed on opposite sides of the seat body; a plurality of locking holes are respectively disposed on opposite sides of the top of the housing, the locking protrusions being inserted into the locking holes to lock the connecting seat and the housing together.

[0008] Optionally, the connecting seat further includes a spring arm disposed between the seat body and the latching protrusion. The opposite sides of the seat body are the outer and inner sides of the machine body that are away from and close to the coffee machine. The outer surface of the latching protrusion on the outer side is a plane, and the outer surface of the latching protrusion on the inner side is a slope, so that the outer latching protrusion is first inserted into the corresponding latching hole, and then the inner latching protrusion is inserted into the corresponding latching hole.

[0009] Optionally, a stop block is provided on the side of the connecting shaft away from the lug. The width of the stop block is less than or equal to the width of the slot, and the length of the stop block is greater than the width of the slot. The stop block is used to prevent the connecting shaft from coming out of the slot. When the cover is rotated to the point where the connecting arm is parallel to the length direction of the stop block, the connecting shaft can be separated from the connecting arm.

[0010] Optionally, the rotation range of the lid relative to the box body is 0° to m°, where m° ≤ 100°, and the angle β between the length direction of the stop block and the height direction of the box body is selected from a to b. 0 < a < b < m.

[0011] Optionally, a ≥ k × (mb); where 10 ≤ k ≤ 30.

[0012] Optionally, the water tank has a flat cubic structure, and the tank cover rotates relative to the tank body along the width direction of the water tank.

[0013] The present invention provides a coffee machine in a second aspect, comprising a body and a water tank as described in any one of the first aspects.

[0014] Optionally, the water tank is located on the rear side of the machine body.

[0015] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by providing a connecting seat on the inner side of the top of the box body and a connecting shaft for connecting the box cover on the connecting seat, the structure of the box body is simplified and the manufacturing difficulty of the box body is reduced. This is especially true compared to directly setting the connecting shaft on the box body. Furthermore, since the connecting shaft is not set on the box body, the parting edge that would otherwise be present on the box body due to the presence of the connecting shaft is avoided, thus improving the aesthetics of the box body. By providing a connecting arm with a strip-shaped hole on the inner side of the box cover, the box cover can be rotatably slidably connected to the connecting shaft through the strip-shaped hole. By changing the box cover from a covered opening posture to an open opening posture by first moving upwards and then rotating to one side of the box body, the box cover can avoid the opening of the box body, increasing the opening range and facilitating the user's water filling operation.

[0016] When the lid changes from its normally open position to its open and concealed position, it needs to be rotated to the top of the container before sliding down and closing the container. This allows the lid to fit onto the container vertically. When the water tank is fixed to the coffee machine, it also shortens the distance between the lid and the machine body, resulting in a more compact overall structure for the coffee machine.

[0017] Furthermore, by configuring elastic arms and locking protrusions distributed on opposite sides of the connector body, and by providing locking holes on the housing, the connector can be engaged with the housing via the locking protrusions and locking holes. By making the outer surface of the outer locking protrusion flat, it can be parallel to the outer surface of the housing after being inserted into the locking hole, thus ensuring the overall integrity of the housing's outer surface and serving a decorative function. By making the outer surface of the inner locking protrusion beveled, the outer locking protrusion can be inserted into the corresponding locking hole first, and then the inner locking protrusion can be inserted into the corresponding locking hole, ensuring that the connector can be smoothly installed inside the housing.

[0018] Furthermore, by setting a stop block on the side of the connecting shaft away from the lug, the connecting shaft is effectively prevented from coming out of the slot. By making the width of the stop block less than or equal to the width of the slot, and the length of the stop block greater than the width of the slot, the connecting shaft can be separated from the connecting arm when the cover is rotated to the point where the connecting arm is parallel to the length direction of the stop block. This makes it easier for the user to install the cover onto the connecting seat and remove the cover from the connecting seat.

[0019] Furthermore, by allowing the lid to rotate relative to the box body within a range of 0° to m°, and by selecting the angle β between the length direction of the stop block and the height direction of the box body from a to b, and ensuring that a ≥ k × (mb), it not only prevents the connecting shaft from coming out of the strip hole on the connecting arm during the rotation of the box body, but also allows the user to remove the lid after rotating the box body at a specific angle.

[0026] Furthermore, it should be noted that in the description of this utility model, mm represents millimeter, cm represents centimeter, and m represents meter.

[0027] like Figure 1 As shown, in some embodiments of this utility model, the coffee machine 001 includes a body 100 and a water tank 200. The body 100 is used to make coffee, and the water tank 200 is used to supply water to the body 100.

[0028] Furthermore, the water tank 200 is located at the rear of the machine body 100 so that the water tank 200 can be hidden by the machine body 100 when the coffee machine 001 is placed on the countertop, thereby improving the overall aesthetics of the coffee machine 001.

[0029] Of course, in other embodiments of this utility model, those skilled in the art can also place the water tank 200 at any feasible position such as the top side, left side, or right side of the body 100 as needed.

[0030] like Figures 2 to 10 As shown, in some embodiments of this utility model, the water tank 200 includes a tank body 210, a connecting seat 220, and a tank cover 230.

[0031] like Figure 2 and Figure 5As shown, the box 210 has an upward-facing opening 211.

[0032] like Figure 5 , Figures 7 to 10 As shown, the connecting seat 220 is located on the inner side of the top of the housing 210, and the connecting seat 220 is provided with a connecting shaft 221.

[0033] like Figures 2 to 10 As shown, the box cover 230 includes a cover body 231 and a connecting arm 232 disposed inside the cover body 231. The connecting arm 232 is provided with a slotted hole 2321. The box cover 230 is rotatably and slidably connected to the connecting shaft 221 through the slotted hole 2321, so that the box cover 230 can be in an attitude of covering the opening 211 (e.g., Figure 8 As shown) can move upwards first (as shown) Figure 8 and Figure 9 (As shown) Then rotate to one side of box 210 (as shown) Figure 9 and Figure 10 The method shown is changed to the open position of opening 211 (as shown). Figure 10 (As shown).

[0034] Those skilled in the art will understand that by providing a connecting seat 220 on the inner side of the top of the housing 210, and providing a connecting shaft 221 on the connecting seat 220 for connecting the housing cover 230, the structure of the housing 210 is simplified and the manufacturing difficulty of the housing 210 is reduced. This is especially true compared to directly setting the connecting shaft 221 on the housing 210. Furthermore, since the connecting shaft 221 is not set on the housing 210, the parting edge that would otherwise be present on the housing 210 due to the presence of the connecting shaft 221 is avoided, thus improving the aesthetics of the housing 210. By providing a connecting arm 232 with a strip-shaped hole 2321 on the inner side of the housing cover 230, the housing cover 230 can be rotatably slidably connected to the connecting shaft 221 through the strip-shaped hole 2321. By changing the position of the lid 230 from covering the opening 211 to opening the opening 211 by first moving it upward and then rotating it to one side of the box body 210, the lid 230 can avoid the opening 211 of the box body 210, thereby increasing the opening range of the opening 211 and making it more convenient for users to add water.

[0035] When the lid 230 changes from its normally open position 211 to its open and covered position, it first needs to rotate to be directly above the body 210 before sliding down and closing the body 210. This allows the lid 230 to fit onto the body 210 vertically. When the water tank 200 is fixed to the coffee machine 001, the distance between the lid 230 and the body 100 of the coffee machine 001 is also shorter, resulting in a more compact overall structure for the coffee machine 001.

[0036] like Figures 2 to 7As shown, in some embodiments of this utility model, multiple locking holes 212 are respectively provided on opposite sides of the top of the housing 210, so that the connecting seat 220 can be installed in the housing 210 through the locking holes 212.

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this utility model, the connecting seat 220 includes a seat body 222 and a lug 223. The seat body 222 is fixedly connected to the housing 210. The lug 223 is disposed on the top side of the seat body 222, and the connecting shaft 221 is disposed on the inner side of the lug 223.

[0038] Those skilled in the art will understand that by placing the connecting shaft 221 inside the lug 223, the connecting shaft 221 can be hidden by the lug 223 when the tank cover 230 is opened, thereby improving the aesthetics of the water tank 200 when water is being added. It also prevents the connecting shaft 221 from breaking due to accidental bumping by the user.

[0039] like Figures 2 to 7 As shown, in some embodiments of this utility model, the connecting seat 220 further includes a plurality of locking protrusions 224 disposed on the bottom side of the seat body 222, the plurality of locking protrusions 224 being distributed on opposite sides of the seat body 222. The locking protrusions 224 are embedded in the locking holes 212 to engage the connecting seat 220 with the housing 210.

[0040] like Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments of this utility model, the connecting seat 220 further includes a spring arm 225 disposed between the seat body 222 and the latching protrusion 224.

[0041] from Figures 1 to 7 As can be seen, the opposite sides of the seat 222 are the outer and inner sides of the body 100, which is away from and close to the coffee machine 001. The outer surface of the outer protrusion 224 is flat, and the outer surface of the inner protrusion 224 is inclined. The outer protrusion 224 is first inserted into the corresponding hole 212, and then the inner protrusion 224 is inserted into the corresponding hole 212.

[0042] Those skilled in the art will understand that by setting the outer surface of the outer protrusion 224 to a flat surface, the outer protrusion 224, after being inserted into the slot 212, can be parallel to the outer surface of the housing 210, thereby making the outer surface of the housing 210 completely intact and serving as a decorative element. By setting the outer surface of the inner protrusion 224 to a bevel, the outer protrusion 224 can be inserted into the corresponding slot 212 first, and then the inner protrusion 224 can be inserted into the corresponding slot 212, ensuring that the connecting seat 220 can be smoothly installed inside the housing 210.

[0043] In addition, in other embodiments of this utility model, those skilled in the art can also use any other feasible connection method to fix the connecting seat 220 and the housing 210 together as needed, such as interference fit, welding, bonding, etc.

[0044] like Figure 2 and Figure 5 As shown, in some embodiments of this utility model, a stop block 226 is provided on the side of the connecting shaft 221 away from the lug 223. The width of the stop block 226 is less than or equal to the width of the strip hole 2321, and the length of the stop block 226 is greater than the width of the strip hole 2321.

[0045] Among them, the stop block 226 is used to prevent the connecting shaft 221 from coming out of the strip hole 2321.

[0046] like Figure 11 As shown, in some embodiments of this utility model, when the box cover 230 is rotated to the point where the connecting arm 232 is parallel to the length direction of the stop block 226, the connecting shaft 221 can be separated from the connecting arm 232, so as to facilitate the user to install the box cover 230 onto the connecting seat 220 and to remove the box cover 230 from the connecting seat 220.

[0047] like Figure 9 and Figure 10 As shown, in some embodiments of this utility model, the rotation range of the box cover 230 relative to the box body 210 is 0° to m°.

[0048] Where m° ≤ 100°. m can be any feasible value such as 75, 80, 90, 95, 100, etc.

[0049] like Figure 10 and Figure 11 As shown, in some embodiments of this utility model, the angle β between the length direction of the stop block 226 and the height direction of the box 210 is selected from a to b.

[0050] Where 0 < a < b < m, so that the connecting arm 232 of the box cover 230 is parallel to the length direction of the stop block 226 in the middle of the rotation stroke, thereby removing the box cover 230.

[0051] Furthermore, a≥k×(mb); where 10≤k≤30, and k can be any feasible value such as 10, 12, 15, 18, 20, 21, 26, 28, 30, etc.

[0052] Those skilled in the art will understand that by ensuring that a, b, and m satisfy the aforementioned functional relationship, the connecting arm 232 of the tank cover 230 can be quickly rotated past a position parallel to the length direction of the stop block 226 when the user normally opens and closes the tank cover 230. This prevents the connecting arm 232 of the tank cover 230 from accidentally disengaging from the connecting shaft 221, thereby ensuring the reliability of the water tank 200 during use. Simultaneously, it also ensures that the tank cover 230 maintains a position where the connecting arm 232 is parallel to the length direction of the stop block 226 (e.g., Figure 11 (as shown) and the position where the lid 230 is fully open (as shown) Figure 10 (As shown) is quite similar, and it also makes it easier for users to remove the box cover 230.

[0053] like Figures 1 to 6 As shown, in some embodiments of this utility model, the water tank 200 has a generally flattened cubic structure, making the overall structure of the coffee machine 001 more compact. The lid 230 rotates relative to the body 210 along the width direction of the water tank 200. Simply put, the connecting seat 220 has a connecting shaft 221 at each of its left and right ends, and the lid 230 has a connecting arm 232 at each of its left and right ends, allowing the lid 230 to open the body 210 towards the rear of the coffee machine 001.

[0054] The following reference Figures 8 to 10 The following is a brief description of the usage of the tank cover 230 of the water tank 200 in some embodiments of this utility model.

[0055] When the user needs to open the lid 230, first... Figure 8 The lid 230 shown is pulled upwards to... Figure 9 The position shown, and then... Figure 9 The lid 230 shown flips backward to Figure 10 The location is shown. The user can then add water to the tank 210.

[0056] When the user needs to close the lid 230, first... Figure 10 The lid 230 shown flips forward to Figure 9 At the position shown, then make Figure 9 The lid 230 shown in the image slides down to... Figure 8 The location shown.

[0057] like Figure 5 and Figure 11As shown, when the user needs to remove the cover 230, the cover 230 is slowly rotated to a position where the connecting arm 232 is parallel to the length direction of the stop block 226. Then, the connecting arm 232 is pressed from the outside in, causing it to deform and disengage from the connecting shaft 221 and the stop block 226. When the user needs to install the cover 230 onto the housing 210, the length direction of the connecting arm 232 is aligned with the length direction of the stop block 226. Then, the connecting arm 232 is pressed from the outside in, causing it to deform. This aligns the slotted hole 2321 with the stop block 226, and the stop block 226 and the connecting shaft 221 are inserted into the slotted hole 2321.

[0058] Based on the foregoing description, those skilled in the art will understand that the coffee machine 001 of this utility model, by placing the water tank 200 on the rear side of the body 100 and opening the locking holes 212 only on the front and rear sides of the housing 210, can hide the locking holes 212 on the water tank 200 when the coffee machine 001 is in use, thereby improving the overall aesthetics of the coffee machine 001.

[0059] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.
