Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a drip-proof single-cup coffee machine. Background Technology

[0002] Single-cup drip coffee makers are very popular because they brew only one cup of coffee at a time, making them ideal for single people as brewing more would be wasteful.

[0003] Single-cup coffee machines typically use a coffee cup to hold the coffee. Once the coffee has flowed into the cup and the machine's spout stops dispensing, users usually assume all the coffee is out and remove the cup. However, since most single-cup drip coffee machines lack a control valve at the spout, a few drops of residual coffee can collect in the coffee basket after the cup is removed and drip onto the receiving tray. If this tray isn't cleaned promptly, it can harbor bacteria and mold, causing inconvenience and a poor user experience. Furthermore, since the coffee cup is usually placed directly on the machine's tray, external factors, such as accidental bumps, can cause it to tip over, spilling coffee onto the counter and requiring cleaning, which also adds to the inconvenience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drip-proof single-cup coffee machine, which has advantages such as drip prevention, prevention of coffee cup displacement, and adjustable support height, thus solving the problems mentioned in the background art.

[0005] A drip-proof single-cup coffee machine includes a coffee machine body, an inlet funnel inside the coffee machine body, a coffee basket on the inlet funnel, a drip-proof funnel between the coffee basket and the inlet funnel, and a flow-stopping device at the bottom of the drip-proof funnel.

[0006] Preferably, the flow-stopping device includes a flow-stopping element and a return spring. The flow-stopping element is inserted at the liquid outlet at the bottom of the anti-drip funnel, and the return spring is fitted onto the flow-stopping element and located between the bottom of the flow-stopping element and the outer bottom of the anti-drip funnel.

[0007] Preferably, a linkage activation mechanism is provided on the outer side of the coffee machine body, which is used to control the state of the flow-stopping device through the anti-drip funnel.

[0008] Preferably, the linkage starting mechanism includes a starting linkage and a pressing component. The two ends of the starting linkage are rotatably mounted on the two outer sides of the coffee machine body. The pressing component is disposed inside the coffee machine body and located on the two outer sides of the anti-drip funnel. The pressing component is fixedly mounted on the starting linkage and is driven by the starting linkage.

[0009] Preferably, the starting linkage includes a handle, and the handle has linkage mounting portions at both ends, with linkage fixing holes on the linkage mounting portions.

[0010] Preferably, the handle is provided with linkage rods on both sides, one end of the linkage rod is fixedly connected to the handle, and the other end is connected to the pressing element.

[0011] Preferably, the pressing member and the linkage rod form a detachable fixed connection.

[0012] Preferably, it also includes a start switch, which is located on the side of the linkage start mechanism and is activated by the linkage start mechanism through contact and pressing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model of an anti-drip single-cup coffee machine is equipped with a flow-stopping device and a linkage activation mechanism. When the linkage activation mechanism is pulled down, the anti-drip funnel can be pressed down to press the flow-stopping device, which opens the seal on the outlet of the anti-drip funnel, allowing coffee to flow from the coffee basket through the anti-drip funnel and coffee funnel into the coffee cup. After the coffee is collected, the linkage activation mechanism is pulled up, which seals the outlet of the anti-drip funnel with the flow-stopping device. This effectively prevents residual coffee from dripping onto the bottom tray after the cup is removed, thus effectively avoiding hygiene problems such as bacterial growth and mold on the coffee machine tray due to uncollected dripped coffee.

[0016] 2. In this utility model of anti-drip single-cup coffee machine, when the handle of the linkage activation mechanism is pulled down, it is located on both sides and the front side of the coffee cup below. This can effectively limit the movement range of the coffee cup and prevent the coffee cup from being knocked to the outside of the coffee machine tray due to external factors. This can prevent the coffee cup from tipping over and spilling coffee on the table, and can also prevent the coffee cup from shifting significantly when brewing coffee.

[0017] 3. In this utility model of anti-drip single-cup coffee machine, the linkage rod is arc-shaped. When the handle of the linkage activation mechanism is not pulled down, the pressing part is positioned on both sides of the pressing part of the anti-drip funnel, which does not restrict the removal or installation of the anti-drip funnel. This makes it convenient for users to remove the coffee basket and anti-drip funnel for cleaning at any time.

[0018] 4. This utility model of a drip-proof single-cup coffee machine is equipped with a support base, which can be removed for easy cleaning. In addition, the support base has at least one height mode to accommodate coffee cups of different heights. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of the present invention, the product of the present invention will be further described in detail below with reference to embodiments and accompanying drawings.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1 to 4 As shown, a drip-proof single-cup coffee machine includes a coffee machine body 1. Inside the coffee machine body 1 is a dispensing funnel 2, and a coffee basket 8 is mounted on the dispensing funnel 2. A drip-proof funnel 3 is positioned between the coffee basket 8 and the dispensing funnel 2. The bottom of the drip-proof funnel 3 is equipped with a flow-stopping device. The flow-stopping device includes a flow-stopping element 4 and a return spring 5. The flow-stopping element 4 is inserted into the dispensing port at the bottom of the drip-proof funnel 3, and the return spring 5 is fitted onto the flow-stopping element 4 and located between the bottom of the flow-stopping element 4 and the outer bottom of the drip-proof funnel 3. A linkage actuation mechanism is provided on the outside of the coffee machine body 1. This linkage actuation mechanism is used to control the state of the flow-stopping device via the drip-proof funnel 3.

[0028] It should be noted that in this embodiment, the flow-stopping component 4 has an "I"-shaped cross-section, with a sealing head at its upper end and a spring-loaded limiting seat at its lower end. During installation, the flow-stopping component 4 is inserted into the outlet of the anti-drip funnel 3, so that the sealing head can seal the outlet of the anti-drip funnel 3. The diameter of the sealing head is larger than the diameter of the outlet of the anti-drip funnel 3, so that the sealing head can seal the outlet of the anti-drip funnel 3. Then, the return spring 5 is fitted onto the rod of the flow-stopping component 4, and the spring-loaded limiting seat is fixedly installed at the lower end of the rod of the flow-stopping component 4 by riveting, gluing, or threading. The return spring 5 is positioned between the bottom outer side of the anti-drip funnel 3 and the spring limiting seat. The inner diameter of the return spring 5 is larger than the outer diameter of the outlet of the sealed anti-drip funnel 3, but smaller than the maximum outer diameter of the spring limiting seat, which can prevent the return spring 5 from falling off. The bottom surface of the stopper 4 is also provided with a protrusion, so that when the stopper 4 is pressed against the inner bottom surface of the outlet funnel 2, there will still be an outlet gap between the bottom surface of the stopper 4 and the inner bottom surface of the outlet funnel 2, which makes it easy for coffee to flow out from the outlet of the outlet funnel 2. The coffee basket 8 is placed inside the anti-drip funnel 3, which makes it easy for the user to take it out and pour coffee powder at any time.

[0029] like Figures 1 to 4As shown, the linkage starting mechanism includes a starting linkage 6 and a pressing component 7. The two ends of the starting linkage 6 are rotatably mounted on the two outer sides of the coffee machine body 1. The pressing component 7 is located inside the coffee machine body 1 and on the two outer sides of the anti-drip funnel 3. The pressing component 7 is fixedly mounted on the starting linkage 6 and is driven by the starting linkage 6. The starting linkage 6 includes a handle 601, and the two ends of the handle 601 are provided with linkage mounting parts 602. The linkage mounting parts 602 are provided with linkage fixing holes. The handle 601 is provided with linkage rods 603 on both sides. One end of the linkage rod 603 is fixedly connected to the handle 601, and the other end is connected to the pressing component 7. The pressing component 7 and the linkage rod 603 form a detachable fixed connection. It also includes a start switch 10, which is located on the side of the linkage starting mechanism and is activated by the linkage starting mechanism through contact and pressing. It also includes a replaceable support base 9, which is set on the base of the coffee machine body 1 and located directly below the liquid dispensing funnel 2. The support base 9 has at least one variable height mode.

[0030] It should be noted that in this embodiment, the anti-drip funnel 3 has pressing parts extending outward on both sides. The two ends of the handle 601 are rotatably mounted on both sides of the coffee machine body 1. The linkage rod 603 extends to both sides of the outer shell of the coffee machine body 1. One end of the pressing member 7 passes through the outer shell of the coffee machine body 1 and is detachably fixedly connected to the linkage rod 603 by threads. The linkage rod 603 is arc-shaped. When the starting linkage 6 is in the horizontal state (not pulled down), the pressing member 7 is located above and to the side of the pressing part of the anti-drip funnel 3. This does not restrict the removal or installation of the anti-drip funnel 3, making it convenient for the user to remove the anti-drip funnel 3 for cleaning at any time. When the starting linkage 6 is pulled down, the starting linkage 6 drives the pressing member 7 through the arc-shaped linkage rod 603, causing the pressing member 7 to move downward in an arc shape, which can press on the pressing part of the anti-drip funnel 3, thereby pressing the anti-drip funnel 3 downward and opening the stop device. In this embodiment, the coffee machine body 1 has clearance grooves for the pressing member 7 on both sides of its outer shell. These clearance grooves are provided along the movement path of the pressing member 7, facilitating the movement of the pressing member 7 by the linkage rod 603. The start switch 10 is electrically connected to the control system of the coffee machine body 1 and is located above or below the linkage mounting part 602 of the handle 601, forming a contact connection with the linkage mounting part 602. When the handle 601 of the linkage start mechanism is pulled down, the start switch 10 can be pressed through the linkage mounting part 602, allowing the coffee machine body 1 to start the power supply and boil water. In this embodiment, one side of the support base 9 is flat, and the other side is recessed, allowing the support base 9 to have two variable height modes, making it convenient for users to use cups of different heights. Furthermore, the support base 9 is placed directly on the base of the coffee machine body 1, making it easy for users to remove and clean.

[0031] Usage: In this invention, after the user puts water and coffee powder into the coffee machine body 1, when the user pulls down the handle 601, the handle 601 drives the linkage rod 603, which in turn drives the pressing member 7 to press down the anti-drip funnel 3. This causes the anti-drip funnel 3 to press down the return spring 5, thereby moving the sealing head of the stop member 4 away from the outlet of the anti-drip funnel 3, releasing the sealing restriction on the outlet of the anti-drip funnel 3. At the same time, pulling down the handle 601 will press the start switch 10, causing the coffee machine body 1 to start the power supply and begin boiling water. When the coffee machine body 1 completes the boiling of water according to the control program and delivers the water to the coffee basket 8, the brewed coffee comes out from the coffee basket 8 and flows through the outlet of the anti-drip funnel 3. The coffee flows out into the outlet funnel 2, and then from the outlet of the outlet funnel 2 into the cup below. When the coffee dripping is complete and the user needs to remove the coffee, he pulls the handle 601 upwards, and at the same time pulls the pressing part 7 through the linkage rod 603, releasing the pressing restriction on the anti-drip funnel 3. This allows the anti-drip funnel 3 to spring up under the action of the return spring 5, so that the sealing head of the stopper 4 can seal the outlet of the anti-drip funnel 3. This effectively prevents the coffee residue in the coffee basket 8 from flowing out and dripping onto the tray of the coffee machine body 1, thus effectively avoiding the hygiene problem of coffee residue on the tray. When the handle 601 is pulled up, the pressing restriction on the start switch 10 is released, cutting off the control power of the coffee machine body 1.
