Technical Field
[0001] This utility model relates to the field of beverage preparation technology, specifically to a coffee liquid mixing and preparation device. Background Technology
[0002] Coffee is a widely used food ingredient, used to process beverages, bread and other products. The use of coffee usually involves using roasted coffee beans as raw material, adding water to extract coffee extract, and then adding it to the product.
[0003] According to the patent titled "A Coffee Liquid Mixing and Blending Device" (patent publication number: CN214546980U, patent publication date: 2021-11-02), the device comprises a storage tank, a glass box, a ruler, a second motor, a circular shaft, a blending box, a first heating plate, a second heating plate, a liquid storage tank, and a controller. The storage tanks on the left and right sides contain water and enzyme solution, respectively. Opening the rubber piston pours the water and enzyme solution into the coffee bean germ filter until it covers the filter screen by 1.5-2.5 cm. The controller controls the first heating plate to heat the liquid storage tank at the top of the second horizontal plate. The process increases the fermentation and concentration rate. After 30 minutes, the liquid enters the glass chamber on the right side through a pipe until it reaches the horizontal line at the bottom of the ruler. Then, the rubber piston is closed. At this point, the liquid and fermentation slurry, with a volume ratio of 1:1, are transported to the mixing tank through the pipe and the rubber piston. The controller controls the second motor to drive the rotating shaft and the second heating block to heat and accelerate the mixing and concentration rate of the coffee liquid. The concentrated coffee liquid is then transported to the storage tank through the pipe and the rubber piston for temporary storage. This process solves the problems of slow mixing and concentration rate and poor mixing volume ratio accuracy of general coffee liquid mixing and blending devices, greatly improving the practicality of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-6 This utility model provides a technical solution: a coffee liquid mixing and preparation device, including a box 1, a drain pipe 4 fixedly installed at the bottom of the box 1, and a fourth solenoid valve 5 fixedly installed on the outside of the drain pipe 4. A processing mechanism 3 is provided inside the box 1 for grinding, drip-filtering, and mixing coffee beans. A quantitative feeding mechanism 2 is provided inside the top of the box 1 for weighing and feeding coffee beans to improve the accuracy of coffee bean addition. The quantitative feeding mechanism 2 includes:
[0027] The flow unit 21 is located inside the housing 1 and is used to control the amount of additives and water added.
[0028] Weighing unit 22, located at the bottom of flow unit 21, includes weighing box 221. A connecting seat 222 is fixedly installed on the rear side of weighing box 221, and a weighing plate 223 is rotatably installed on the outside of connecting seat 222. An electronic scale 2210 is installed inside the weighing plate 223 for weighing coffee beans. An electric push rod 229 is rotatably installed on one side of weighing box 221 via a connecting column.

A rotating shaft 225 is fixedly installed on one side of weighing box 221, and the middle part of the rotating rod 226 is rotatably connected to the rotating shaft 225. A sliding column 227 is fixedly installed on one end of the rotating rod 226. A sliding groove 224 is opened on one side of weighing plate 223, and one end of the sliding column 227 slides inside the sliding groove 224 to realize the rotation of weighing plate 223.
[0029] The first solenoid valve 213, the third solenoid valve 219, the second solenoid valve 216, and the fourth solenoid valve 5 are all model 2W-250-25. The first flow meter 214 and the second flow meter 217 are model CBLDE-L. The electronic scale 2210 is model HDW600. The electric push rod 229 is model SLEL205. When coffee beans inside the second space of the storage bin 211 fall into the weighing bin 221 through the opening of the third solenoid valve 219, the coffee beans are weighed by the electronic scale 2210. When the specified amount is reached, 219 closes, thus realizing the weighing of coffee beans. At this time, the electric push rod 229 pushes the rotating rod 226 to rotate through the sleeve 228, causing the sliding column 227 to slide inside the sliding groove 224, causing the weighing plate 223 to rotate, and the coffee beans fall into the processing mechanism 3 for processing, thereby realizing the accurate weighing and feeding of coffee beans and improving the quality and stability of coffee liquid.
[0030] In this embodiment, the flow unit 21 includes a storage tank 211 fixedly installed on the top of the housing 1. The storage tank 211 is divided into three spaces.

[0031] The first space of the storage tank 211 is filled with additives, and the third space of the storage tank 211 is filled with water. The amount of additives and water is accurately measured by the first flow meter 214 and the second flow meter 217 to ensure that the coffee liquid is consistent in taste, flavor and concentration each time it is prepared.
[0032] In this embodiment, the processing mechanism 3 includes a conical cylinder 31 fixedly installed inside the housing 1, and the top end of the drain pipe 4 passes through the housing 1 and is fixedly connected to the bottom of the conical cylinder 31. A grinding box 33 is fixedly installed on the top of the conical cylinder 31, and a grinding wheel 34 is rotatably installed inside the grinding box 33. The grinding wheel 34 is driven by a motor to rotate and grind coffee beans. A filter box 32 is fixedly installed inside the conical cylinder 31 for drip filtering of the ground coffee bean powder.

[0033] Coffee beans fall into the grinding chamber 33. The motor outside the grinding chamber 33 drives the grinding wheel 34 to rotate and grind the coffee beans. The ground powder falls into the filter tank 32. At this time, the second solenoid valve 216 opens, and the water in the storage tank 211 is poured into the filter tank 32 through the second discharge pipe 215 for drip filtration. The second flow meter 217 detects the water flow rate. When a certain amount is reached, the second flow meter 217 closes. The drip-filtered coffee liquid falls into the conical cylinder 31. At this time, the first solenoid valve 213 opens and the additive in the storage tank 211 is poured into the conical cylinder 31 through the first discharge pipe 212. The first flow meter 214 detects the additive flow rate. When a certain amount is reached, the first solenoid valve 213 closes. Then, the drive motor 36 runs and drives the stirring rod 37 to rotate and stir and mix the coffee liquid and additive. The finished coffee liquid is discharged through the drain pipe 4 through the fourth solenoid valve 5.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] During operation, additives are first added to the first space of the storage bin 211, coffee beans are added to the second space, and water is added to the third space. At this time, the third solenoid valve 219 opens and the coffee beans in the second space fall into the weighing bin 221. The coffee beans are weighed by the electronic scale 2210. When the specified amount is reached, the third solenoid valve 219 closes, completing the weighing of the coffee beans. Then, the electric push rod 229 pushes the rotating rod 226 to rotate through the sleeve 228, causing the sliding column 227 to slide inside the sliding groove 224, causing the weighing plate 223 to rotate, and the coffee beans fall into the processing mechanism 3.
[0036] Next, the coffee beans fall into the grinding chamber 33. The motor outside the grinding chamber 33 drives the grinding wheel 34 to rotate and grind the coffee beans. The powder formed after grinding falls into the filter tank 32. At this time, the second solenoid valve 216 opens, and the water in the storage tank 211 is poured into the filter tank 32 through the second discharge pipe 215 for drip filtration. The second flow meter 217 detects the water flow rate and closes when a certain amount is reached.
[0037] Then, the drip-filtered coffee liquid falls into the conical cylinder 31. At this time, the first solenoid valve 213 opens and the additives in the storage tank 211 are poured into the conical cylinder 31 through the first discharge pipe 212. The flow rate of the additives is detected by the first flow meter 214. When a certain amount is reached, the first solenoid valve 213 closes. Then, the drive motor 36 runs and drives the stirring rod 37 to rotate and stir and mix the coffee liquid and the additives. After completion, the coffee liquid is discharged through the drain pipe 4 through the fourth solenoid valve 5.
