Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a flip-top locking structure for a coffee machine. Background Technology

[0002] Currently, coffee machines on the market use coffee powder packets as the extraction material. The coffee machine has a cup holder with a cup cavity inside. The coffee powder packet is placed into the filter, and then the filter is placed into the cup cavity. The lid used to seal the cup cavity is closed, and the coffee machine injects a mixture of high-temperature, high-pressure water and steam into the coffee powder packet to extract coffee liquid.

[0003] For coffee machine lids that open like flip-tops, a locking mechanism needs to be installed between the lid and the main unit to prevent the lid from not closing securely during use.

[0004] In existing technologies, locking mechanisms are typically designed for pressing to open. A button on the top of the cover is used to unlock the mechanism, allowing the cover to open. However, this unlocking method requires the user to apply additional force to other parts of the cover during the opening process, as the cover needs to be pressed down while simultaneously flipping it upwards. This is inconvenient. Utility Model Content

[0012] By adopting the above technical solution, the baffle of the unlocking component abuts against the upper edge of the movable groove, limiting the excessive rotation of the unlocking component and preventing damage to the mechanism due to misoperation.

[0013] A further provision of the above technical solution is that the flip cover includes a bottom cover and a top cover with side panels, the front end of the side panels is provided with a notch, and the notch and the bottom cover are assembled to form an active groove for the unlocking mechanism to move.

[0014] A further provision of the above technical solution is that the lower end of the bottom cover has a matching part that fits into the host. The limiting groove is provided at the matching part.

[0015] A further provision of the above technical solution is that an anti-disengagement structure is provided between the connecting rod and the locking tongue, and between the connecting rod and the unlocking component, wherein the anti-disengagement structure causes the two ends of the connecting rod to form a stop with the locking tongue and the unlocking component respectively in the axial direction.

[0016] By adopting the above technical solution, the connecting rod, unlocking component, and locking tongue are connected by the misalignment of the anti-disengagement protrusions and protrusion grooves to prevent the components from falling off and ensure long-term stability.

Detailed Implementation

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] like Figure 1-9 As shown in the figure, this embodiment discloses a flip-top locking structure for a coffee machine.

[0032] A flip-top locking structure for a coffee machine includes a flip-top 200 hinged to a main unit 100, which closes onto the main unit 100 to form a coffee cavity; the flip-top 200 has a water channel inside, which draws water from a water supply device inside the main unit 100 and injects hot water into the coffee cavity through a water outlet 201 on the lower end face of the flip-top 200; the bottom of the coffee cavity has a liquid outlet. The rear end of the flip cover 200 is hinged to the main unit 100, and the front end can rotate relative to the main unit 100 about the axis L of the rear end, thereby forming an upward flip structure. The flip cover 200 has a locking structure inside, the locking structure including... Unlocking element 300, which is exposed on the flip cover 200 and can be rotated relative to the flip cover 200 between a first position and a second position by manual operation; The locking tongue 400 is movably disposed within the flip cover 200 and moves linearly under the action of the unlocking member 300. The locking tongue 400 has a retracted state and an extended state relative to the flip cover 200. The host 100 is provided with a locking groove 102 that engages with the locking tongue 400 in the extended state to lock it; Link 500, which is located inside the flip cover 200 and is hinged at both ends to the unlocking member 300 and the locking tongue 400 respectively, and transmits the rotational motion of the unlocking member 300 and converts it into the linear motion of the locking tongue 400. The rotation direction of the flip cover 200 is consistent with the driving direction of the human hand on the unlocking component (300).

[0033] The above is the basic scheme of this embodiment.

[0034] Specific reference Figure 1 and Figure 2 As shown, the flip cover 200 is hinged to the main unit 100. The front side of the main unit 100 has a notch 212, and the notch 212 has a groove 101 that mates with the lower end of the end cap. The locking groove 102 is located on the side wall of the groove 101. The rear end of the flip cover 200 is set as a hinge end, which is connected to the main unit 100 through a pivot, so that the flip cover 200 can rotate around the axis L and form an upward flip structure relative to the main unit 100. When the flip cover 200 is closed on the main unit 100, the lower part is embedded in the groove 101 to form a closed coffee cavity. At the same time, the upper end surface of the flip cover 200 and the upper end surface of the main unit 100 form a complete external structure.

[0035] Place the coffee powder bag into the coffee chamber, close the flip cover 200, operate button 1 on the top of the flip cover 200 to set the coffee machine mode, the coffee machine starts, the water supply device in the main unit 100 inputs heated hot water into the flip cover 200, and outputs it to the coffee chamber through the water passage inside the flip cover 200 to extract the coffee liquid, and the extracted coffee liquid is output to the outside through the liquid outlet of the coffee chamber.

[0036] The locking structure is located inside the flip cover 200. In its natural state, the locking tongue 400 extends to the outside and engages with the locking groove 102 on the main unit 100 to lock the flip cover 200 onto the main unit 100, preventing the flip cover 200 from flipping up relative to the main unit 100. Operate the unlocking component 300, which drives the connecting rod 500 to swing. The connecting rod 500 drives the locking tongue 400, causing the locking tongue 400 to retract into the flip cover 200. At this time, the locking tongue 400 exits the locking groove 102, and the flip cover 200 is unlocked from the main unit 100. Then, operate the flip cover 200 to flip it up from the notch 212, exposing the coffee container.

[0037] In this embodiment, the rotation direction of the flip cover 200 and the driving direction of the human hand on the unlocking member 300 are set to the same direction. That is to say, when the flip cover 200 needs to be opened, the human hand operates the unlocking member 300 in the same direction, which simultaneously drives the flip cover 200 to open, thus avoiding the inconvenience caused by the inconsistency between the unlocking direction and the flip cover opening direction.

[0038] One side of the unlocking component 300 is located inside the flip cover 200 and is hinged to the flip cover 200. Under the action of external force, it can rotate from the first position to the second position. During the rotation, it drives the connecting rod 500 to move, thereby driving the bolt 400 to move from the extended state to the retracted state. At this time, the bolt 400 separates from the lock groove 102 on the main unit 100, and the unlocking is completed.

[0039] Specifically, the unlocking component 300 and the flip cover 200 are connected by a hinge shaft 310, and the operating end 301 and the driving end 302 of the unlocking component 300 are located on both sides of the hinge shaft 310, respectively. The first end 501 of the connecting rod 500 is hinged to the driving end 302 of the unlocking member 300, and the second end 502 is hinged to the locking tongue 400.

[0040] Specific reference Figure 3 As shown, the unlocking member 300 has a hinge shaft 310 extending to both sides inside the flip cover 200. The flip cover 200 has a rotating hole corresponding to the hinge shaft 310, so that the unlocking member 300 can rotate around the axis M of the hinge shaft 310.

[0041] The unlocking component 300 is located on both sides of the hinge shaft 310, namely the operating end 301 and the driving end 302. When the user applies force to the operating end 301, the operating end 301 drives the unlocking component 300 to rotate, thereby causing the driving end 302 to rotate synchronously.

[0042] The first end 501 of the connecting rod 500 is hinged to the driving end 302 of the unlocking member 300. When the driving end 302 rotates around the axis M, the first end 501 of the connecting rod 500 also rotates around the axis M synchronously. At the same time, the first end 501 of the connecting rod 500 rotates relative to the driving end 302 of the unlocking member 300. That is, the connecting rod 500 can rotate around the axis N of the first hinge shaft 310 between the connecting rod 500 and the driving end 302.

[0043] When the first end 501 of the connecting rod 500 rotates, the entire connecting rod 500 is in a swinging motion. At this time, the second end 502 of the connecting rod 500 rotates around the axis M along with the first end 501, and the second end 502 also rotates around the axis N.

[0044] In order to ensure that the swinging link 500 drives the latch 400 only in a linear direction, in this embodiment, the flip cover 200 is provided with a limiting groove 202. The limiting groove 202 is used to allow the latch 400 to extend and to constrain the movement direction of the latch 400.

[0045] Specific reference Figure 4 and Figure 5 As shown, a limiting groove 202 is provided on the flip cover 200, and both ends along the X-axis are set as openings, thereby forming a through groove communicating with the interior of the flip cover 200. The latch 400 moves along the through groove in the X-axis direction and extends or retracts relative to the flip cover 200. When the latch 400 is in the extended or retracted state, it is partially located within the limiting groove 202, thereby limiting the latch 400 in any position.

[0046] In this embodiment, the flip cover 200 is provided with a movable groove 203 that can accommodate the rotation of the unlocking member 300. The operating end 301 of the unlocking member 300 extends to the outside of the movable groove 203, and the driving end 302 is located inside the movable groove 203.

[0047] Specific reference Figure 4 and Figure 5 As shown, the movable groove 203 is located at the front end of the flip cover 200, allowing the unlocking member 300 to extend outside the flip cover 200 or be exposed inside the movable groove 203. The hinge shaft 310 is located inside the unlocking groove 102. When a person operates the unlocking member 300, the operating end 301 of the unlocking member 300 rotates, and the part located inside the movable groove 203 can move up and down within the movable groove 203.

[0048] Based on the above settings, the operating end 301 of the unlocking component 300 is limited by the movable slot 203, thereby limiting the range of motion of the unlocking component 300 and ensuring that the range of motion of the locking structure is controllable.

[0049] Preferably, in this embodiment, the unlocking member 300 is provided with a baffle 320, which extends upward from the upper end surface of the unlocking member 300 and is located inside the movable groove 203; When the unlocking component 300 is in the first position, the upper end of the baffle 320 abuts against the upper edge of the movable groove 203.

[0050] Specific reference Figure 6 and Figure 7 As shown, the upper surfaces of the baffle 320 and the unlocking member 300 are vertically arranged. When the unlocking member 300 is in the first position, the baffle 320 is located inside the movable groove 203 and abuts against the upper edge of the movable groove 203. At this time, due to the interference between the baffle 320 and the upper edge of the movable groove 203, the unlocking member 300 cannot rotate counterclockwise. When the unlocking member 300 is rotated to the second position by manual operation, the baffle 320 rotates clockwise simultaneously, moving away from the upper edge of the movable groove 203.

[0051] In this embodiment, the flip cover 200 includes a bottom cover 220 and a top cover 210 with a side panel 211. The front end of the side panel 211 is provided with a notch 212. The notch 212 and the bottom cover 220 are assembled to form an active groove 203 for the unlocking member 300 to move.

[0052] The flip cover 200 is a combined shell structure, with the edge of the top cover 210 extending downward to form a side panel 211, and the movable groove 203 is provided on the side panel 211.

[0053] The bottom cover 220 has a matching part 221 protruding from its lower end, which is fitted into the host 100. The limiting groove 202 is provided at the matching part 221.

[0054] Specific reference Figure 8 As shown, the bottom cover 220 is a cover plate structure, and the middle of the cover plate structure protrudes downward to form a matching part 221. When the bottom cover 220 and the top cover 210 are assembled, the bottom cover 220 is embedded in the side panel 211, and only the matching part 221 is exposed below. When the flip cover 200 is closed on the main unit 100, the matching part 221 is embedded in the groove 101 of the main unit 100 to form a coffee cavity.

[0055] The limiting groove 202 is provided on the matching part 221 and has an opening facing the front end, so that the locking tongue 400 can extend to the front end of the flip cover 200.

[0056] In addition, in this embodiment, anti-disengagement structures are provided between the connecting rod 500 and the locking tongue 400, and between the connecting rod 500 and the unlocking member 300. The anti-disengagement structures make the two ends of the connecting rod 500 form stops with the locking tongue 400 and the unlocking member 300 in the axial direction, respectively.

[0057] Specific reference Figure 9 As shown, taking the anti-detachment structure between the first end 501 of the connecting rod 500 and the unlocking member 300 as an example, the driving end 302 of the unlocking member 300 is provided with a short shaft, and the first end 501 of the connecting rod 500 is provided with a rotating groove that can accommodate the rotation of the short shaft; the anti-detachment structure is an anti-detachment protrusion 302.1, which interferes with the edge of the rotating groove. The groove wall of the rotating groove has only one recessed protrusion groove 503 that can accommodate the insertion of the anti-detachment protrusion 302.1. During installation, the position of the anti-detachment protrusion 302.1 is aligned with the protrusion groove 503, the short shaft is inserted into the rotating groove, and the connecting rod 500 and the unlocking member 300 are installed. After installation, the anti-detachment protrusion 302.1 is rotated to a position misaligned with the protrusion groove 503, thereby preventing the rotating shaft from detaching from the rotating groove.

[0058] To prevent the anti-detachment structure from failing during rotation, in this embodiment, when the unlocking member 300 and the connecting rod 500 rotate relative to each other, the anti-detachment protrusion 302.1 has a rotation path. At the same time, except for the assembly position, other positions on the rotation path do not pass through the protrusion groove 503, thereby preventing the anti-detachment protrusion 302.1 from rotating to the position of the protrusion groove 503 and exiting from the protrusion groove 503 during the relative rotation of the unlocking member 300 and the connecting rod 500.

[0059] The anti-disengagement structure between the connecting rod 500 and the locking tongue 400 is the same as the structure described above, and will not be repeated here.

[0060] In this embodiment, for ease of operation, the operation end 301 is provided with an operation plate 330 extending to the outside of the flip cover 200, and the operation plate 330 is set at an angle relative to the drive end 302.

[0061] Preferably, in this embodiment, the operation panel 330 is set at an obtuse angle relative to the drive end 302 or the unlocking component 300 body.

[0062] When the unlocking component 300 is in the first position, the main body of the unlocking component 300, the part inside the flip cover 200, is tilted. At this time, the operating plate 330 is in a horizontal position. When the operating plate 330 is lifted up, driving the unlocking component 300 to rotate to the second position, the outer end of the operating plate 330 tilts up, while the main body of the unlocking component 300 inside the flip cover 200 is in a horizontal position.

[0063] When the unlocking member 300 rotates from the first position to the second position, it generates a driving force on the first end 501 of the connecting rod 500. In this embodiment, the first position of the unlocking member 300 is set to an inclined state, so that the driving end 302 generates a thrust in the inclined direction on the connecting rod 500, thereby causing the first end 501 of the connecting rod 500 to rotate counterclockwise, driving the entire connecting rod 500 to rotate counterclockwise, so that the second end 502 of the connecting rod 500 moves backward in the horizontal direction.

[0064] Based on the above settings, it is easier for users to operate the control panel 330.

[0065] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
