Description

Technical Field

[0001] This utility model relates to the field of drip coffee brewing auxiliary equipment, and in particular to a drip coffee extraction stand that prevents side leakage. Background Technology

[0002] Drip coffee bags offer both convenience and a flavor close to freshly ground coffee, making them an important category in daily coffee consumption. The traditional brewing method involves attaching the drip bags to the rim of a cup and pouring hot water into the bag for extraction. However, this method is problematic because cups often have flat or curved rims, creating gaps between the bottom of the drip bag and the cup wall when it's suspended. During extraction, the coffee tends to flow along the bottom of the bag or the outside of the cup, not only staining the cup and table but also wasting coffee.

[0003] Moreover, the drip bag is only supported by two small drip handles on the rim of the cup. When water is poured, the impact of the water flow can easily cause the coffee bag to shake and slip off, which not only affects the uniformity of extraction, but may also cause the coffee bag to fall into the cup as a whole.

[0004] To address the above problems, this utility model provides a leak-proof drip coffee extraction holder. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a leak-proof drip coffee extraction holder, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a leak-proof drip coffee extraction stand, including a base and a base plate hinged to the middle of the front side of the base. Two telescopic support members are symmetrically arranged at the upper end of the base. A top seat is fixed to the top of each of the two telescopic support members, and a bracket is hinged to both top seats. A flow guide funnel is fixed to the inner side of the bracket. A protruding edge is integrally formed at the top of the flow guide funnel. The inner wall of the protruding edge has multiple elastic clips arranged in a rectangular array. The bracket has rotating seats connected to both ends of its bottom. The top seat has a U-shaped groove at its upper end, and a through hole and a positioning screw hole are respectively provided on the two sides of the top seat. An adjusting screw is also connected to the top seat. A through hole is provided through the surface of the rotating seat. When the rotating seat is located in the U-shaped groove, the adjusting screw is screwed into the positioning screw hole through the through hole and the through hole to squeeze the top seat and limit and fix the rotating seat.

[0007] As a further technical solution of this utility model, the top surface of the rotating seat is machined with positioning screw holes II, and multiple through holes II are equally spaced on both ends of the bracket. The two ends of the bracket are respectively fixed to the two rotating seats by adjusting screws II through the through holes II and screwed into the positioning screw holes II.

[0008] As a further technical solution of this utility model, the telescopic support includes a lower support rod and an upper support rod, wherein the upper support rod is a hollow structure and its inner diameter is adapted to the outer diameter of the lower support rod; The upper support rod has multiple adjustment holes evenly spaced on its surface. The outer surface of the top of the lower support rod has an elastic protrusion connected by a spring. The top of the lower support rod is slidably inserted into the upper support rod, and the elastic protrusion at the top of the lower support rod is locked in the adjustment hole on the surface of the upper support rod.

[0009] As a further technical solution of this utility model, the guide funnel is made of high-temperature resistant food-grade rubber, and the elastic clamp is made of elastic plastic.

[0010] As a further technical solution of this utility model, a groove is provided at the front end of the base, and a shaft is symmetrically installed on both sides of one end of the base plate. A torsion spring is sleeved on the shaft, and one end of the base plate is rotatably connected to the groove through the shaft. One end of the torsion spring is fixed to the shaft, and the other end of the torsion spring is fixed to the inner wall of the groove.

[0011] As a further technical solution of this utility model, a limiting screw hole is machined in the middle of the side of the base, and a limiting screw rod is internally threaded into the limiting screw hole. A limiting hole is opened in the middle of one end face of the base plate corresponding to the limiting screw hole. One end of the limiting screw rod is screwed out of the limiting screw hole and extends into the limiting hole to limit the base plate.

[0012] As a further technical solution of this utility model, a water storage tank is provided on the upper surface of the base plate, and a filter screen is placed on the upper surface of the base inside the water storage tank.

[0013] This invention provides a leak-proof drip coffee extraction holder, which has the following advantages compared with the prior art: 1. This design provides a leak-proof drip coffee brewing holder. By using the physical constraint of the flow funnel, the flow path of the coffee liquid is changed. Utilizing the surface tension and gravity of the liquid, the coffee liquid flows vertically downward into the cup only along the inner wall of the flow funnel, avoiding diffusion to the surroundings and completely solving the problems of side leakage and splashing. Moreover, the elastic clip applies a continuous clamping force to the drip coffee bag. This clamping force is greater than the impact force and shaking inertia of the water flow on the coffee bag when pouring water, achieving dynamic stability of the coffee bag during the brewing process and preventing it from slipping or shaking.

[0014] 2. This design provides a leak-proof drip coffee extraction stand. The telescopic support can be adjusted in height by the cooperation of the elastic protrusion and the adjustment hole to accommodate cups of different depths. The length of the stand can be adjusted by the cooperation of the second adjustment screw and the second through hole to accommodate cups of different diameters. In addition, the angle of the stand can be adjusted by the cooperation of the rotating seat and the first adjustment screw to ensure that the outlet of the guide funnel is always directly above the cup rim.

[0015] 3. This design features a leak-proof coffee extraction stand with a drip tray. The base plate's water reservoir and filter plate can catch any residual liquid dripping from the brewed coffee bag, preventing contamination of the work surface. The base plate can be automatically folded using a torsion spring, and can be secured after extension using a limiting screw. Furthermore, the stand can rotate 90° parallel to the telescopic support, reducing the overall size of the stand and making it easy to store and carry. In addition, the telescopic support can be shortened, significantly reducing storage space. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution for a leak-proof drip coffee extraction stand: a leak-proof drip coffee extraction stand includes a base 1 and a base plate 5 hinged to the middle of the front side of the base 1. The front end of the base 1 has a groove. A shaft 52 is symmetrically installed on both sides of one end of the base plate 5. A torsion spring 53 is sleeved on the shaft 52. One end of the base plate 5 is rotatably connected to the groove through the shaft 52. One end of the torsion spring 53 is fixed to the shaft 52, and the other end of the torsion spring 53 is fixed to the inner wall of the groove.

[0020] A limiting screw hole 12 is machined in the middle of the side of the base 1. A limiting screw rod 11 is connected to the internal thread of the limiting screw hole 12. A limiting hole 54 is opened in the middle of one end face of the base plate 5 corresponding to the limiting screw hole 12. One end of the limiting screw rod 11 is screwed out of the limiting screw hole 12 and extends into the limiting hole 54 to limit the angle of the base plate 5. The limiting hole 54 and the limiting screw hole 12 are coaxially arranged, and when the base plate 5 and the base 1 form a 90° angle, the limiting hole 54 and the limiting screw hole 12 are aligned.

[0021] A water storage tank is provided on the upper surface of the base plate 5, and a filter screen plate 51 is placed on the upper surface of the base 1 inside the water storage tank. This is used to collect the dripping residual liquid and filter impurities, and also to facilitate placing the cup on the filter screen plate 51 so that the lower opening of the guide funnel 41 is directly above the cup.

[0022] Two telescopic support members 2 are symmetrically arranged at the upper end of the base 1. The telescopic support member 2 includes a lower support rod 21 and an upper support rod 24. The upper support rod 24 is a hollow structure and its inner diameter is adapted to the outer diameter of the lower support rod 21. Multiple adjustment holes 23 are evenly spaced on the surface of the upper support rod 24. The top outer surface of the lower support rod 21 is connected to an elastic protrusion 22 by a spring. The top of the lower support rod 21 is slidably inserted into the upper support rod 24, and the elastic protrusion 22 at the top of the lower support rod 21 is locked in the adjustment hole 23 on the surface of the upper support rod 24, thereby realizing the length adjustment of the bracket 4.

[0023] Both telescopic support members 2 have a top seat 3 fixed at their top ends. Both top seats 3 are hinged to a bracket 4. Both ends of the bracket 4 are connected to a rotating seat 47. The top end of the top seat 3 has a U-shaped groove 31. The two sides of the top seat 3 are respectively provided with a through hole 33 and a positioning screw hole 34. An adjusting screw 32 is also connected to the top seat 3. A through hole 48 is provided through the surface of the rotating seat 47. When the rotating seat 47 moves in the U-shaped groove 31, one end of the adjusting screw 32 can be screwed into the positioning screw hole 34 through the through hole 33 and the through hole 48. The butterfly cap at one end of the adjusting screw 32 will continuously press the top seat 3, so that its inner wall is pressed against the outer wall of the rotating seat 47. The rotating seat 47 is fixed in the U-shaped groove 31 by friction, so that the angle of the bracket 4 can be adjusted. In addition, one end of the limiting screw 11, the adjusting screw 32, and the adjusting screw 45 are all provided with butterfly caps.

[0024] The top surface of the rotating seat 47 is machined with positioning screw holes 46. Multiple through holes 44 are equally spaced on both ends of the bracket 4. The two ends of the bracket 4 are respectively fixed to the two rotating seats 47 by adjusting screws 45 through the through holes 44 and screwed into the positioning screw holes 46. The rotating seats 47 and the bracket 4 can be connected and fixed by adjusting screws 45.

[0025] A flow guide funnel 41 is fixed to the inner side of the bracket 4. A protruding edge 42 is integrally formed at the top of the flow guide funnel 41. The inner wall of the protruding edge 42 has multiple elastic clips 43 arranged in a rectangular array. The flow guide funnel 41 is made of high-temperature resistant food-grade rubber, and the elastic clips 43 are made of elastic plastic, such as PP. The elastic clips 43 are used to clamp the edge of the drip bag coffee bag, and the flow guide funnel 41 is used to constrain the flow path of the coffee liquid.

[0026] The working principle of this utility model is as follows: When in use, press the elastic protrusion 22 of the telescopic support 2 to disengage it from the adjustment hole 23 of the upper support rod 24, slide the relative position of the lower support rod 21 and the upper support rod 24 until the height of the bracket 4 is adapted to the depth of the cup, such as the outlet of the guide funnel 41 being 5-10mm from the mouth of the cup. Then release the elastic protrusion 22 to make it snap into the corresponding adjustment hole 23 to complete the height fixation. Furthermore, by unscrewing the second adjusting screw 45, the relative position of the rotating seat 47 and the support 4 is adjusted along the length of the support 4 until the guide funnel 41 on the support 4 is located directly above the cup. Then, the second adjusting screw 45 is inserted through the second through hole 44 of the support 4 and screwed into the second positioning screw hole 46 of the rotating seat 47 to complete the length fixation. Then, loosen the adjusting screw 32, rotate the bracket 4, so that it drives the rotating seat 47 to rotate in the U-shaped groove 31 of the top seat 3 until the guide funnel 41 is in a vertical state, ensuring that the coffee liquid flows vertically into the cup. Then tighten the adjusting screw 32, so that it passes through the through hole 33 and the through hole 48 and is screwed into the positioning screw hole 34. By pressing the side wall of the top seat 3, it is pressed against the outer wall of the rotating seat 47, thereby completing the angle fixation. Furthermore, rotate the base plate 5 so that it rotates around the shaft 52 to form a 90° angle with the base 1, and then screw in the limiting screw 11 so that one end of it extends into the limiting hole 54 of the base plate 5 to fix the angle of the base plate 5. Then place the filter screen plate 51 in the water storage tank on the upper surface of the base 1, and then place the cup body on the filter screen plate 51 so that the cup mouth is just below the guide funnel 41. When brewing, unfold the two tabs of the drip coffee bag and place it into the flow funnel 41. The elastic clip 43 on the inner wall of the protruding edge 42 clamps the edge of the tab, ensuring that the bottom of the coffee bag is in contact with the inner wall of the flow funnel 41. Then, slowly pour hot water into the drip coffee bag. The coffee liquid formed after the hot water is extracted by the coffee powder flows vertically downward into the cup along the inner wall of the flow funnel 41, avoiding side leakage. After brewing, remove the cup. The drip coffee bag can be left in the funnel 41 or removed and temporarily placed on the filter plate 51. The dripping residue will be collected in the water tank. After use, the funnel 41, the elastic clip 43 and the filter plate 51 can be rinsed directly or disassembled for cleaning. Finally, unscrew the limiting screw 11. Under the reset action of the torsion spring 53, the base plate 5 automatically folds to fit snugly against the base 1, as shown. Figure 4 and 5 As shown, loosen the tightening screw 32 on the top seat 3, causing the bracket 4 to rotate 90 degrees within the U-shaped groove 31 via the rotating seat 47, thus becoming parallel to the telescopic support 2, and positioning the guide funnel 41 between the two telescopic supports 2, as shown. Figure 4 and 5 As shown, tighten the adjusting screw 32 to fix the rotating seat 47 and the top seat 3, thus completing the folding and fixing process; Finally, adjust the pressing elastic protrusion 22 to shorten the length of the telescopic support 2, reduce the overall space occupied by the bracket, and make it easier to store.
