Description

Technical Field

[0001] This utility model belongs to the technical field of coffee making equipment, and specifically provides a coffee machine. Background Technology

[0002] In modern life, coffee machines have become widely used beverage preparation devices in homes, offices, and other settings. Their core function is to heat and pressurize water from the tank to produce coffee, satisfying users' needs for convenient coffee. As users' demands for quality of life continue to rise, in addition to the taste and efficiency of coffee preparation, the space adaptability, ease of operation, and overall aesthetics of coffee machines have become important factors for users. Among these, the water tank, as a key water supply component, has a direct impact on the user experience due to its installation method and location design.

[0003] Currently, most coffee machine water tanks on the market adopt a fixed installation or a single-direction detachable design. On the one hand, some coffee machines have their water tanks directly fixed to one side of the main unit (such as the left or right side). While this fixed installation method is simple in structure and stable in connection, it has obvious space limitations in actual use. For example, when the coffee machine is placed on a kitchen countertop near a wall or other furniture, if the fixed side of the water tank faces the wall or furniture, the space for removing and refilling the water tank will be narrow. Users will need to frequently move the entire coffee machine to refill the water tank, which is cumbersome and time-consuming. At the same time, a water tank fixed to one side also makes the coffee machine less adaptable to countertop spaces of different sizes, unable to be flexibly adjusted according to the actual placement environment, and prone to space waste or placement restrictions.

[0004] On the other hand, some coffee machines feature a water tank that can be pulled out or removed from the back of the main unit. While this design avoids the space limitations of a fixed side to some extent, it also has the drawback of inconvenience. When space needs to be reserved in front of the coffee machine (for placing coffee cups or control panels), and the back is close to a wall, pulling out the water tank from the back will be obstructed by the wall. Users need to move the entire coffee machine forward a certain distance to remove the water tank, which not only increases the number of steps but may also cause the coffee machine to shift its position due to frequent movement, affecting the convenience and stability of use. In addition, this type of water tank has poor flexibility in position adjustment, failing to adapt to different user habits and diverse placement environments, and thus failing to meet users' higher demands for coffee machine space adaptability and operational convenience.

[0005] In conclusion, current coffee machines have relatively poor adaptability in terms of water tank space and ease of operation. Summary of the Invention

[0006] One objective of this invention is to solve the problem of poor space adaptability of the water tank in existing coffee machines.

[0007] To achieve the above objectives, this utility model provides a coffee machine, comprising: The main unit has a first water inlet plug-in structure provided on one side and the rear side of its left and right sides respectively; The water tank has a second water inlet plug-in structure that is adapted to the first water inlet plug-in structure on one side perpendicular to the vertical direction. The second water inlet plug-in structure is plugged into the first water inlet plug-in structure to connect the water tank to the main unit, thereby allowing the water tank to supply water to the main unit. The water tank can be selectively installed on one side or the rear side of the main unit.

[0008] Optionally, the first gate insertion structure includes a clearance cavity, and the second gate insertion structure includes an annular protrusion such that the protrusion is embedded in the clearance cavity, thereby allowing the first gate insertion structure and the second gate insertion structure to be inserted together.

[0009] Optionally, the protrusion is a structure made of a flexible material to allow it to deform when the water tank is plugged in or out of the main unit, thereby preventing the protrusion from breaking.

[0010] Optionally, the main unit is provided with a groove at the opening of the clearance cavity, and the coffee machine further includes a baffle slidably installed in the groove so that the baffle selectively opens or covers the clearance cavity.

[0011] Optionally, the outer side of the baffle is provided with a rib, so that the user can slide the baffle by moving the rib.

[0012] Optionally, a first magnetic suction component is provided on one of the rear side and the left and right sides of the main unit; a second magnetic suction component is provided on the water tank, and the second magnetic suction component and the first magnetic suction component can be magnetically attracted together to fix the water tank on one of the rear side or the left and right sides of the main unit.

[0013] Optionally, the second magnetic member is disposed on the top of the water tank; and / or, the second magnetic member is a strip member.

[0014] Optionally, the ratio of the length to the width of the water tank in the horizontal direction is greater than or equal to 3, so that the water tank has a larger side and a smaller side; the second water inlet plug structure is disposed on the larger side.

[0015] Optionally, the water tank located at the rear of the main unit is the same width as the main unit.

[0016] Optionally, the first sprue insertion structure includes a first check valve and a first top post, and the second sprue insertion structure includes a second check valve and a second top post. The first check valve is adapted to the second top post so that when the second sprue insertion structure is inserted into the first sprue insertion structure, the second top post opens the first check valve; the second check valve is adapted to the first top post so that when the second sprue insertion structure is inserted into the first sprue insertion structure, the first top post opens the second check valve.

[0017] 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 first water inlet plug-in structure on one side and the rear side of the main unit, and a second water inlet plug-in structure adapted to the first water inlet plug-in structure on the water tank, the water tank can be selectively installed on one side or the rear side of the main unit via the first and second water inlet plug-in structures. Therefore, this utility model allows users to adjust the position of the water tank relative to the main unit according to the available countertop space, improving the space adaptability of the coffee machine's water tank.

[0018] Furthermore, by setting a groove on the main unit and installing a baffle within the groove, the user can selectively open or close the clearance cavity using the baffle. Specifically, before the second sprue connector is inserted into the first sprue connector, the user manually opens the baffle to open the clearance cavity. After the second sprue connector is removed from the first sprue connector, the user manually closes the baffle to close the clearance cavity.

[0019] Furthermore, by setting a first magnetic attraction component on the main unit and a second magnetic attraction component on the water tank, the water tank and the main unit can be attracted together by the second magnetic attraction component and the first magnetic attraction component, thereby enabling the water tank and the main unit to be doubly fixed by the "first water inlet plug-in structure and the second water inlet plug-in structure" and the "first magnetic attraction component and the second magnetic attraction component".

[0020] Furthermore, by incorporating a first check valve and a first push post into the first water inlet connector structure, and a second check valve and a second push post into the second water inlet connector structure, the first push post opens the second check valve and the second push post opens the first check valve when the second water inlet connector structure is inserted into the first water inlet connector structure. Conversely, when the second water inlet connector structure is removed from the first water inlet connector structure, the first and second check valves automatically close to prevent leakage from the main unit and water tank.

For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0027] Furthermore, it should be noted that in the description of this utility model, mm represents millimeter, cm represents centimeter, and m represents meter.

[0028] like Figures 1 to 4 As shown, in some embodiments of this utility model, the coffee machine 001 includes a main unit 100 and a water tank 200.

[0029] Among them, one of the left and right sides of the host 100 (e.g. Figures 1 to 4 The left and rear sides, as shown, are respectively provided with a first water inlet insertion structure 110 (e.g., as shown on the left side). Figures 2 to 5 (As shown).

[0030] Among them, water tank 200 and vertical direction (such as Figure 1 As shown, a second sprue insertion structure 210 adapted to the first sprue insertion structure 110 is provided on one vertical side (e.g., ...). Figure 6 As shown in the figure, the second water inlet plug-in structure 210 is plugged into the first water inlet plug-in structure 110 to make the water tank 200 connected to the main unit 100, so that the water tank 200 supplies water to the main unit 100.

[0031] like Figures 1 to 3 As shown, the water tank 200 can be selectively installed on one side or the rear side of the main unit 100.

[0032] Optionally, when the water tank 200 is located on one or the rear side of the main unit 100, the water tank 200 is fitted to the main unit 100 to make the structure of the coffee machine 001 more compact and the connection between the water tank 200 and the main unit 100 more stable.

[0033] It should be noted that the water tank 200 and the main unit 100 can be attached to each other surface by surface, or a part of the structure of the water tank 200 can be pressed against the main unit 100.

[0034] Those skilled in the art will understand that by providing a first water inlet plug-in structure 110 on one side and the rear side of the main unit 100, and a second water inlet plug-in structure 210 adapted to the first water inlet plug-in structure 110 on the water tank 200, the water tank 200 can be selectively installed on one side or the rear side of the main unit 100 via the first water inlet plug-in structure 110 and the second water inlet plug-in structure 210. Therefore, this invention allows users to adjust the position of the water tank 200 relative to the main unit 100 according to the available countertop space, improving the space adaptability of the water tank 200 of the coffee machine 001.

[0035] like Figures 2 to 6 As shown, in some embodiments of the present invention, the first sprue insertion structure 110 includes a relief cavity 111, and the second sprue insertion structure 210 includes an annular protrusion 211, so that the protrusion 211 is embedded in the relief cavity 111, and thus the first sprue insertion structure 110 and the second sprue insertion structure 210 are inserted together.

[0036] Furthermore, the cross-section of the protrusion 211 can gradually decrease towards the host 100 so that the outer peripheral surface of the protrusion 211 is a conical surface, thereby making it convenient for the user to insert the protrusion 211 into the clearance cavity 111.

[0037] Furthermore, the protrusion 211 may be a structure made of a flexible material to allow the protrusion 211 to deform when the water tank 200 is inserted or removed from the host 100, thereby preventing the protrusion 211 from breaking.

[0038] Those skilled in the art will understand that, because the protrusion 211 is flexible, even if the water tank 200 is impacted and experiences slight displacement or shaking relative to the main unit 100 during the use of the coffee machine 001, the protrusion 211 can adapt to the movement of the water tank 200 by deforming. This effectively prevents the protrusion 211 from breaking due to force when the water tank 200 is displaced or shaken relative to the main unit 100.

[0039] The flexible material can be any feasible flexible material such as plastic, nylon, rubber, silicone, or metal.

[0040] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the main unit 100 is provided with a groove 101 at the opening of the clearance cavity 111. Furthermore, the coffee machine 001 also includes a baffle 120 slidably installed in the groove 101, so that the baffle 120 selectively opens or closes the clearance cavity 111.

[0041] Before the protrusion 211 is inserted into the clearance cavity 111, the user moves the baffle 120 to open the clearance cavity 111. After the protrusion 211 is pulled out of the clearance cavity 111, the user moves the baffle 120 to cover the clearance cavity 111.

[0042] like Figure 4 As shown, the outer side of the baffle 120 is provided with a protruding rib 121, so that the user can slide the baffle 120 by moving the protruding rib 121, thereby facilitating the user's operation of the baffle 120.

[0043] Furthermore, the side of the protruding rib 121 facing the water tank 200 is flush with the side of the main unit 100 facing the water tank 200, so as to prevent the protruding rib 121 from being too protruding and causing the water tank 200 to be unable to fit together with the main unit 100. Alternatively, those skilled in the art may, as needed, provide a relief groove on the water tank 200 that aligns with the protruding rib 121, so that when the water tank 200 and the main unit 100 are fitted together, the protruding rib 121 is embedded in the groove.

[0044] Furthermore, in other embodiments of this utility model, those skilled in the art can also configure the baffle 120 into any other feasible structure as needed.

[0045] For example, the baffle 120 can be replaced with a removable plug. When the water tank 200 is installed on the right side of the main unit 100, the user removes the plug from the clearance cavity 111 on the right side of the main unit 100 and installs it into the clearance cavity 111 on the rear side of the main unit 100. When the water tank 200 is installed on the rear side of the main unit 100, the user removes the plug from the clearance cavity 111 on the rear side of the main unit 100 and installs it into the clearance cavity 111 on the right side of the main unit 100.

[0046] like Figures 5 to 7 As shown, in some embodiments of this utility model, the first water inlet plug structure 110 further includes a first one-way valve 112 and a first top post 113. Correspondingly, the second water inlet plug structure 210 further includes a second one-way valve 212 and a second top post 213.

[0047] from Figure 5 As can be seen, the first one-way valve 112 and the first top post 113 are both arranged in the clearance cavity 111, and the second one-way valve 212 and the second top post 213 are both arranged in the annular protrusion 211.

[0048] The first check valve 112 is adapted to the second top column 213 so that when the second water inlet plug structure 210 is plugged into the first water inlet plug structure 110, the second top column 213 opens the first check valve 112.

[0049] Accordingly, the second check valve 212 is adapted to the first top post 113 so that when the second water inlet plug structure 210 is plugged into the first water inlet plug structure 110, the first top post 113 opens the second check valve 212.

[0050] In simple terms, when the second water inlet connector 210 is inserted into the first water inlet connector 110, the first push rod 113 opens the second check valve 212, and the second push rod 213 opens the first check valve 112. When the second water inlet connector 210 is pulled out of the first water inlet connector 110, the first check valve 112 and the second check valve 212 automatically close, preventing leakage from the main unit 100 and the water tank 200. For this purpose, both the first check valve 112 and the second check valve 212 are automatically closing check valves, and each may have a return spring.

[0051] Since opening the one-way valve by means of the top column is a conventional technique in this field and is well known to those skilled in the art, it will not be described in detail here.

[0052] like Figures 1 to 4 and Figure 6 As shown, in some embodiments of this utility model, the ratio of the length to the width of the water tank 200 in the horizontal direction is greater than or equal to 3, so that the water tank 200 has a larger side and a smaller side. The second water inlet insertion structure 210 is provided on the larger side, so that the coffee machine 001 is more compact overall.

[0053] The ratio of the length to the width of the water tank 200 in the horizontal direction can be any feasible value such as 3, 3.3, 3.5, 3.8, 4, 5, 8, etc.

[0054] like Figure 3 As shown, in some embodiments of this utility model, the water tank 200 located at the rear of the main unit 100 is the same width as the main unit 100, so as to make the coffee machine 001 more aesthetically pleasing overall.

[0055] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, one side of the rear and left and right sides of the host 100 (e.g.) Figure 4 and Figure 5 The right side shown in the diagram is provided with a first magnetic attraction member 130.

[0056] like Figure 6As shown, in some embodiments of this utility model, a second magnetic component 220 is provided on the water tank 200. The second magnetic component 220 and the first magnetic component 130 can be magnetically attracted together to fix the water tank 200 to one side of the rear or left and right sides of the main unit 100.

[0057] Wherein, at least one of the first magnetic attraction member 130 and the second magnetic attraction member 220 can be any feasible magnet such as neodymium iron boron magnet, samarium cobalt magnet, alnico magnet, iron chromium cobalt magnet, etc. For example, the first magnetic attraction member 130 is a magnet, and the second magnetic attraction member 220 is a metal strip.

[0058] In some embodiments of this utility model, the first magnetic attraction component 130 may be disposed inside the host 100 to avoid the first magnetic attraction component 130 being exposed and affecting the aesthetics of the host 100.

[0059] Furthermore, the first magnetic attraction member 130 located on one side of the rear or left and right sides of the host 100 can be one or more.

[0060] from Figure 6 As can be seen, the second magnetic suction component 220 is set on the strip component at the top of the water tank 200.

[0061] Those skilled in the art will understand that by providing a first magnetic attraction component 130 on the main unit 100 and a second magnetic attraction component 220 on the water tank 200, the water tank 200 and the main unit 100 can be attracted together by the second magnetic attraction component 220 and the first magnetic attraction component 130, thereby enabling the water tank 200 and the main unit 100 to be doubly fixed by the "first water inlet insertion structure 110 and the second water inlet insertion structure 210" and the "first magnetic attraction component 130 and the second magnetic attraction component 220".

[0062] The following reference Figures 1 to 7 The following is a brief explanation of the process of changing the position of the water tank 200 in some embodiments of this utility model.

[0063] When the water tank 200 needs to be moved from the right side to the rear side of the main unit 100, remove the water tank 200 from the main unit 100. Then, move the baffle 120 on the left side of the main unit 100 to cover the clearance cavity 111 on the right side of the main unit 100. Next, move the baffle 120 on the rear side of the main unit 100 to open the clearance cavity 111 on the rear side of the main unit 100. Finally, insert the protrusion 211 on the water tank 200 into the clearance cavity 111 on the rear side of the main unit 100 until the water tank 200 is in contact with the main unit 100, and the first magnetic member 130 and the second magnetic member 220 are attracted together.

[0064] When the water tank 200 needs to be moved from the rear side of the main unit 100 to the right side of the main unit 100, the operation method is basically the same as the above operation method, so it will not be explained separately.

[0065] Furthermore, in some embodiments of this utility model, the water tank 200 includes a tank body (not marked in the figure) and a cover (not marked in the figure) disposed on the top side of the tank body. The cover is detachably installed on the tank body so as to open the cover when water needs to be added to the tank body.

[0066] 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.
