[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-12 The technical solution provided by the present invention specifically includes the following embodiments: Example: A coffee machine with an independent water path of a refrigeration system includes a base 1, an extraction mechanism 2 is provided at the front upper portion of the base 1, a water tank mechanism 3 is provided at the rear upper portion of the base 1, and a detection mechanism 4 is provided at the middle upper portion of the base 1: The extraction mechanism 2 includes a protective shell 218, which is fixedly connected to the middle side of the top wall of the base 1. The top wall of the base 1 is fixedly connected to a water pump 203. The output end of the water pump 203 is connected to one end of a pump outlet pipe 207. The other end of the pump outlet pipe 207 is connected to an electromagnetic valve 206. The rear wall side of the electromagnetic valve 206 is connected to one end of a hot water inlet pipe 208. The other end of the hot water inlet pipe 208 is connected to a heating device 205. The output end of the heating device 205 is connected to one end of a hot water outlet pipe 209. The other end of the hot water outlet pipe 209 is connected to the front wall side of the electromagnetic valve 206. The electromagnetic valve 206 is connected to one end of a hot water inlet pipe 208. The other side of the rear wall of 206 is connected to one end of the cold water inlet pipe 212, the other end of the cold water inlet pipe 212 is connected to the refrigeration device 202, the output end of the refrigeration device 202 is connected to one end of the cold water outlet pipe 211, the other end of the cold water outlet pipe 211 is connected to the other side of the front wall of the solenoid valve 206, the bottom side of the solenoid valve 206 is connected to one end of the main water outlet pipe 213, the other end of the main water outlet pipe 213 is connected to the extraction chamber 201, the extraction chamber 201 is fixedly connected to the protective shell 218, a handle 215 is engaged with the bottom of the extraction chamber 201, and a plurality of buttons 216 are fixedly connected to the front wall of the protective shell 218.

[0020] The user snaps the handle 215 filled with coffee powder into the coffee machine and then controls the coffee machine by pressing the button 216 set on the protective shell 218 to select hot brewing coffee or cold brewing coffee. When hot brewing coffee is needed, the user presses the button 216 corresponding to hot brewing, so that the water pump 203 draws water from the water tank mechanism 3 and sends it to the solenoid valve 1 206 through the pump outlet pipe 207, and then enters the hot water inlet pipe 208 through the solenoid valve 1 206. The hot water inlet pipe 208 allows the water to enter the heating device 205 for heating. When heated to a suitable temperature, the heated hot water is sent back to the solenoid valve 1 206 through the hot water outlet pipe 209 and is sent to the extraction chamber 201 through the main water outlet pipe 213 connected to the solenoid valve 1 206, thereby mixing with the coffee powder in the handle 215 and extracting hot coffee. When cold brew coffee is needed, the user only needs to install the handle 215 filled with coffee powder on the coffee machine and press the button 216 corresponding to cold brew. At this time, the water pump 203 will pump water from the water tank mechanism 3 and send it into the solenoid valve 1 206 through the pump outlet pipe 207. When the water enters the solenoid valve 1 206, it will enter the cold water inlet pipe 212 through the solenoid valve 1 206 and enter the connected refrigeration device 202 through the cold water inlet pipe 212. The refrigeration device 202 can cool the incoming water to a suitable temperature, and then send the cooled water out through the cold water outlet pipe 211 and back to the solenoid valve 1 206. Finally, the cooled water is sent into the extraction chamber 201 through the main water outlet pipe 213 connected to the solenoid valve 1 206 and mixed with the coffee powder in the handle 215 for cold brew, so that cold coffee can be directly extracted.

[0021] A drain groove 219 is provided on the front side of the top wall of the base 1 , and a drain plate 214 is engaged with the top of the drain groove 219 .

[0022] By providing the drain plate 214 and the drain trough 219, excess water flowing out of the extraction chamber 201 can be collected when the coffee machine is in use. When the excess water flows out of the extraction chamber 201, it will fall on the drain plate 214 and enter the drain trough 219 through the drain plate 214 for collection. The drain plate 214 can be used to place a container for receiving coffee while ensuring that water passes through.

[0023] The other end of the heating device 205 is connected to one end of the hot steam pipe 210, and the other end of the hot steam pipe 210 is connected to the steam pipe 204. The output end of the steam pipe 204 passes through the outer wall of the protective shell 218, and the front part of one side of the protective shell 218 is rotatably connected to a knob 217.

[0024] When water enters the heating device 205 for heating, hot steam is generated, and the hot steam generated during heating is sent into the steam pipe 204 through the hot steam pipe 210. At this time, when the user needs to use steam to perform operations such as frothing milk, the steam pipe 204 can be inserted into the milk and steam can be sprayed out to perform the frothing operation.

[0025] The water tank mechanism 3 includes a water tank shell 301, which is fixedly connected to the rear side of the top wall of the base 1. An inner water tank 303 is engaged with the water tank shell 301. The front and rear walls of the inner water tank 303 are provided with multiple slots 304. A partition 305 is slidably connected to the middle slot 304. Both side walls of the multiple slots 304 are provided with grooves 307. Sealing strips 306 are slidably connected to the multiple grooves 307. One end of each of the multiple sealing strips 306 is fixedly connected to the inner wall of the groove 307 near the inner wall of the groove 307. The other ends of the multiple springs 309 are fixedly connected to the inner wall of the groove 307. A chamber 315 is provided at the lower part of the water tank shell 301. The inner top wall of the chamber 315 is fixedly connected with solenoid valve 2 310 twice. The top ends of the two solenoid valves 2 310 respectively penetrate the two sides of the inner bottom wall of the inner water tank 303 and are provided with evenly distributed water grooves 312 on the outer periphery. The inner bottom wall of the chamber 315 is connected with the input end of the water pump 203. The multiple sealing strips 306 are slidably connected with guide rods 308. The ends of the multiple guide rods 308 away from the sealing strips 306 penetrate the side walls of the sealing strips 306 and are fixedly connected to the inner walls of the grooves 307. The multiple springs 1 309 are arranged on the outer periphery of the guide rods 308. The water tank cover 302 is rotatably connected to the upper side of the rear wall of the water tank shell 301, and the water tank cover 302 is engaged with the top wall of the inner water tank 303.

[0026] Since the water quality for cold brew and hot brew is slightly different, users often use filtered tap water or slightly cooled hot water to save costs when making hot brew coffee, while it is best to use purified water or cooled boiled water when making cold brew coffee. If you use uncooled boiled water directly, the cooling efficiency will decrease. Therefore, users can choose to divide the space in the water tank according to actual needs. When the space in the water tank needs to be divided, users can open the water tank to divide it. The box cover 302 is inserted into the corresponding card slot 304 on the inner water tank 303, so that the space in the inner water tank 303 can be divided into a cold extraction water area and a hot extraction water area. When the partition 305 is inserted into the card slot 304, it will also contact the sealing strip 306. Since the contact part between the top of the sealing strip 306 and the partition 305 is arc-shaped, when the partition 305 squeezes the sealing strip 306, it will push the sealing strip 306 to move to both sides. When the sealing strip 306 When the spring 1 309 is moved, it will compress the connected spring 1 309. When the spring 1 309 is compressed, it will provide an opposite force, thereby pushing the sealing strip 306 to press against the partition 305 to improve the sealing effect. At the same time, under the action of the guide rod 308, the spring 1 309 can be limited to prevent the spring 1 309 from bending after being compressed to ensure the normal use of the spring 1 309. At this time, when the staff needs to make cold brew coffee, the solenoid valve 2 310 in the cold brew water area will work, so that the cold brew water area The extraction water will enter the solenoid valve 2 310 through the water channel 312 and then enter the chamber 315 through the solenoid valve 2 310. Then the water pump 203 will pump out the water for cold extraction in the chamber 315 for use. When hot extraction of coffee is required, the solenoid valve 2 310 in the hot extraction water area will work, so that the hot extraction water will enter the solenoid valve 2 310 through the water channel 312 and then enter the chamber 315 through the solenoid valve 2 310. Then the water pump 203 will pump out the water for hot extraction in the chamber 315 for use.

[0027] Sealing grooves 311 are provided on both sides of the inner bottom wall of the inner water tank 303. The two sealing grooves 311 are both provided on the outer periphery of the top of the solenoid valve 2 310. One end of the spring 2 313 is fixedly connected to the inner bottom wall of the two sealing grooves 311, and the other end of the two springs 313 is fixedly connected to the sealing block 314.

[0028] When installing the inner water tank 303, after the user inserts the inner water tank 303 into the water tank shell 301, the top of the solenoid valve 2 310 will push the sealing block 314 upward and disengage the sealing groove 311, so that the water in the inner water tank 303 can flow smoothly into the chamber 315. When the user needs to clean the inner water tank 303, the user can directly pull the inner water tank 303 out of the water tank shell 301. At this time, the solenoid valve 2 310 will move downward relatively. Since the sealing block 314 will pull the spring 2 313 to stretch when moving upward, when the solenoid valve 2 310 moves downward relatively, the spring 2 313 will pull the sealing block 314 to reset and snap into the sealing groove 311 for sealing. At this time, even if there is excess water in the inner water tank 303, the inner water tank 303 can be directly disassembled.

[0029] The detection mechanism 4 includes a slide 401, and the two slides 401 are both opened on both sides of the front wall of the water tank shell 301. Knob 2 402 is rotatably connected to both sides of the water tank shell 301. One end of the two knobs 2 402 passes through the slides 401 on both sides and is fixedly connected to bevel gear 1 403. The lower sides of the two bevel gears 1 403 are meshed with bevel gear 2 404. The bottom ends of the two bevel gears 2 404 are fixedly connected to threaded rods 405. The outer peripheries of the two threaded rods 405 are threadedly connected to liquid level sensors 406. The outer peripheries of the top ends of the two threaded rods 405 are rotatably connected to support plates 407. The two support plates 407 are fixedly connected to the inner wall of the slide 401, and the two liquid level sensors 406 are slidably connected to the inner wall of the slide 401.

[0030] The staff can drive the corresponding bevel gear 1 403 to rotate by turning the knob 2 402. When the bevel gear 1 403 rotates, it can drive the meshing bevel gear 2 404 to rotate. The bevel gear 2 404 can drive the threaded rod 405 connected to the bottom to rotate. When the threaded rod 405 rotates, it can drive the liquid level sensor 406 connected to the periphery to move. Since the liquid level sensor 406 slides in the slide groove 401, the slide groove 401 can limit the liquid level sensor 406, so that the liquid level sensor 406 6 will not rotate with the rotation of the threaded rod 405, so that the rotation of the threaded rod 405 can drive the liquid level sensor 406 to move up and down. When the liquid level sensor 406 moves to a suitable position, since the inner water tank 303 is made of transparent material, the liquid level sensor 406 can detect the water level in the inner water tank 303. When the water level is lower than the height of the liquid level sensor 406, the liquid level sensor 406 will transmit a signal, so that the coffee machine will issue a prompt of insufficient water, thereby achieving the effect of facilitating the user to adjust the prompt at different water levels.

[0031] When the coffee machine with an independent water path of a refrigeration system is in operation, when the space in the inner water tank 303 needs to be divided, the user can open the water tank cover 302 and insert the partition 305 into the corresponding slot 304 on the inner water tank 303, thereby dividing the space in the inner water tank 303 into a cold brew water area and a hot brew water area. When the partition 305 is inserted into the slot 304, it will contact the sealing strip 306. Since the contact portion between the top of the sealing strip 306 and the partition 305 is arc-shaped, when the partition 305 presses the sealing strip 306, it pushes the sealing strip 306 to move to both sides. When the sealing strip 306 moves, it compresses the connected spring 1 309. When the spring 1 309 is compressed, it provides an opposite force, thereby pushing the sealing strip 306 to press against the partition 305 to improve the sealing effect. At this time, when the staff needs to make cold brew coffee, the user only needs to put the hand full of coffee powder in the The handle 215 is installed on the coffee machine and the button 216 corresponding to the cold brew is pressed. At this time, the solenoid valve 2 310 in the cold brew water area will work, so that the cold brew water will enter the solenoid valve 2 310 through the water groove 312 and then enter the chamber 315 through the solenoid valve 2 310. Then the water pump 203 will extract the water for cold brew in the chamber 315 and send it to the solenoid valve 1 206 through the pump outlet pipe 207. When the water enters the solenoid valve 1 206, it will pass through the solenoid valve 1 20 6 enters the cold water inlet pipe 212 and enters the connected refrigeration device 202 through the cold water inlet pipe 212. The refrigeration device 202 can cool the incoming water to a suitable temperature. The cooled water is then sent out through the cold water outlet pipe 211 and returned to the solenoid valve 1 206. Finally, the cooled water is sent into the extraction chamber 201 through the main water outlet pipe 213 connected to the solenoid valve 1 206 and mixed with the coffee powder in the handle 215 for cold extraction, thereby directly extracting cold coffee. When hot coffee is needed, the user connects the handle 215 filled with coffee powder to the coffee machine and presses the button 216 corresponding to hot extraction. The solenoid valve 2 310 in the hot extraction water area will work, so that the hot extraction water will enter the solenoid valve 2 310 through the water channel 312 and then enter the chamber 315 through the solenoid valve 2 310. Then the water pump 203 will pump out the water for hot extraction in the chamber 315 and send it to the solenoid valve 1 206 through the pump outlet pipe 207, and enter the solenoid valve 1 206 through the solenoid valve 1 206. In the hot water inlet pipe 208, water enters the heating device 205 through the hot water inlet pipe 208 to be heated. When heated to a suitable temperature, the heated hot water is returned to the solenoid valve 206 through the hot water outlet pipe 209 and is sent into the extraction chamber 201 through the main water outlet pipe 213 connected to the solenoid valve 206. Thereby, the hot water is mixed with the coffee powder in the handle 215 and hot coffee is extracted. In this way, the coffee machine can directly make hot coffee or cold coffee at the same time as needed without the need to add ice cubes later.

[0032] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
