The water path switching module 120 may be a solenoid valve in practical applications. Specifically, the waterway switching module 120 is a three-way electromagnetic valve. The electromagnetic valve is internally provided with a closed cavity, and a plurality of through holes are formed in different positions of the electromagnetic valve, and each through hole can be used as a port to be connected with different external devices. Among them, the solenoid valve having three through holes is called a three-way solenoid valve. A valve body is arranged in a cavity of the electromagnetic valve, and electromagnets are respectively arranged at the positions of the through holes. The magnet coil on which side is electrified, the valve body is attracted to which side, and the valve body can be controlled to move by changing the electric signal applied to the electromagnetic valve, so that the through holes at different positions can be controlled to be conducted or closed.

In one embodiment of the present application, as shown in fig. 1, the coffee brewing water tank 170 further includes: a water amount monitoring module 140; under the condition that the waterway switching module 120 is communicated with the water inlet end and the second water outlet end, when the first water pump 150 works, the liquid in the water supply tank 110 is pumped to the heating module 160 by the first water pump 150 and flows into the coffee brewing water tank 170 after passing through the heating module 160, and when the water quantity monitoring module monitors that the water quantity in the coffee brewing water tank 170 reaches the preset water quantity, the second water pump 180 works to drain the liquid in the coffee brewing water tank 170 to the coffee preparation module 190 so as to obtain coffee at the coffee outlet.

As shown in fig. 1, preferably, a water amount monitoring module is provided between the water supply tank 110 and the first water pump 150. In other words, the water supply tank 110 is connected to the first water inlet of the first water pump 150 through the water amount monitoring module 140. In this way, when the water amount supplied to the coffee brewing water tank 170 is monitored to reach the preset water amount, the first water pump 150 can be controlled to stop working in time, so that the problem that water in the coffee brewing water tank 170 needs to be pumped back by the third water pump 130 due to the fact that more water amount is supplied is avoided. In addition, the water quantity monitoring module is arranged at the position, and quantitative water outlet of 2 water outlets can be simultaneously met only by arranging one flow monitoring module.

In the present embodiment, the coffee brewing process is described as an example of the beverage taking process of the user, but the present utility model is not limited thereto.

When a user needs to take 60ml of coffee, the coffee brewing water tank 170 is empty, the water inlet end and the second water outlet end of the waterway switching module 120 are connected, and meanwhile, purified water in the water supply tank 110 is pumped out under the action of the first water pump 150, and the water flowing through is heated by the heating module 160. The flow rate of the purified water is monitored by the water amount monitoring module 140, and when the amount of the purified water flowing out of the water supply tank 110 reaches 60ml, the first water inlet end and the second water outlet end of the waterway switching module 120, the first water pump 150 and the heating module 160 are closed. When the amount of water stored in the coffee brewing water tank 170 reaches a preset amount of water, the second water pump 180 enters an operating state to pump the hot water in the coffee brewing water tank 170 to the coffee preparation module 190. Since the amount of hot water stored in the coffee brewing water tank 170 is controlled to be 60ml by the water amount monitoring module 140, the hot water stored in the coffee brewing water tank 170 can be directly entirely pumped to the coffee preparation module 190 for beverage preparation. Because the water in the coffee brewing water tank 170 is pumped out each time, no water in the coffee brewing water tank 170 is ensured, bacteria breeding during long-time placement of the water is avoided, and in addition, the water in the coffee brewing water tank 170 does not need to be repeatedly heated, so that energy waste is avoided.

Standard brewing/extraction procedures can be pre-designed in the coffee machine, and the beverage prepared according to the standard brewing/extraction procedures can have optimal flavor. Taking capsule coffee as an example, the extraction rate of the capsule coffee is optimal at 18% -22%, so that a corresponding working procedure can be set with reference to the extraction rate range, the flow rate and the flow rate of the hot water can be changed by adjusting the voltage flow parameters of the first water pump 150 and/or the second water pump 180, and the temperature of the hot water can be adjusted by adjusting the power of the heating element 160, so as to achieve the optimal coffee extraction effect.

However, in daily use, it is highly likely that the user pauses or terminates the preparation of coffee by someone else during the brewing process. At this time, the second water pump 180 stops working, the water in the coffee brewing water tank 170 is not pumped out, so that the capacity of the remaining water in the coffee brewing water tank 170 is difficult to meter, the water yield cannot be accurately controlled in the subsequent process, and meanwhile, the water temperature is gradually reduced, so that the next brewing effect of the user is greatly affected. In order to conserve water resources, the water remaining in the coffee brewing water tank 170 may be drawn back into the water supply tank 110 for recycling. Thus, in some embodiments of the present disclosure, when the coffee machine determines that the current brew sequence is terminated or the pause time exceeds the preset time, the third water pump 130 may be controlled to operate to pump all of the water remaining in the coffee brewing water tank 170 to the water supply tank 110.

In one embodiment of the present application, as shown in fig. 1, the coffee brewing water tank 170 further includes: a water temperature monitoring module configured to monitor the water temperature of the liquid in the coffee brew water tank 170.

Specifically, the water temperature monitoring module is a temperature sensor. In one embodiment, a water level sensor 171 and a temperature sensor 172 may be disposed within the coffee brewing water tank 170. The water level sensor 171 may be disposed at the bottom of the second water storage tank, and the temperature sensor 172 may be disposed at the bottom of the coffee brewing water tank 170.

Along with the progress of society, the life rhythm is also faster and faster, and the efficiency requirement of users on products is also higher and higher. Likewise, when preparing beverages using a coffee net drink, users may also wish to be able to enjoy the beverages as soon as possible. The water level in the coffee brewing water tank 170 may be monitored by the water level sensor 171. Since the water level sensor 171 can detect the water level condition in the coffee brewing water tank 170, a preset water level for judgment as a condition can be set in advance.

When the water level sensor 171 detects that the water level in the coffee brewing water tank 170 reaches a preset water level, it indicates that a certain volume of hot water is stored in the coffee brewing water tank 170, and preparation of the beverage may be started. At this time, the second water pump 180 is controlled to operate to pump hot water in the coffee brewing water tank 170 to the coffee preparation module 190. For example, in a coffee brewing process in which a clean coffee machine brew 60ml, when the water level sensor 171 detects that the water level in the coffee brewing water tank 170 reaches a preset water level, it indicates that the hot water in the coffee brewing water tank 170 has reached 20ml, at which time the preparation of the beverage is started. At the same time, the heating module 160 continuously heats the remaining 40ml of purified water and simultaneously transfers it to the coffee brewing water tank 170 until the heating of the total 60ml of purified water is completed. That is, at this time, the clean water heating line and the beverage preparation line are operated in synchronization until the brewing of the target beverage is completed. Compared with the traditional scheme that the preparation of the beverage is started after the heating of 60ml of purified water is completed, the coffee purified water dispenser utilizes the coffee brewing water tank 170 to temporarily store hot water and the water level sensor 171 to monitor the water level, so that the instant heating and instant use functions can be realized, and the beverage is prepared while the purified water is heated, so that the waiting time of a user is greatly shortened.

In one embodiment of the present application, as shown in fig. 1, the coffee purifying beverage maker further includes an air inlet and outlet pipe 200, a first end of the air inlet and outlet pipe 200 is connected to an air outlet hole of the coffee brewing water tank 170, and a second end of the air inlet and outlet pipe 200 is connected to the water supply tank 110. As the hot water is transferred to the coffee brewing water tank 170, the air pressure in the coffee brewing water tank 170 will rise under the effect of the expansion and contraction. Therefore, by providing the air inlet and outlet pipe, when the air pressure in the coffee brewing water tank 170 is increased, the air can be discharged through the air inlet and outlet pipe, thereby achieving the effect of stabilizing the pressure in the coffee brewing water tank 170.

Fig. 3 is a schematic structural view of a coffee preparation module in one embodiment of the present disclosure, in which the coffee preparation module 190 may be a capsule coffee preparation module. Capsule coffee is usually an aluminum capsule for storing coffee powder ground from coffee beans, and can solve the problems of acid formation, oxidation and the like of ordinary coffee beans or coffee powder when contacting air.

The capsule coffee preparation module may include a capsule housing 191 having a cavity therein, and the capsule housing 191 includes opposing first and second faces. In some embodiments of the present disclosure, the first face may be a top face of the capsule bin 191 and the second face may be a bottom face of the capsule bin 191. The capsule coffee preparation module further comprises a paddle 192, the paddle 192 being rotatably fixed at one end of the first face of the capsule bin 191, the paddle 192 being rotatable about a fixed point. The other end of the first surface of the capsule bin 191 is provided with a through hole, the shape of the through hole can be matched with that of the capsule coffee, the size of the through hole is slightly larger than that of the capsule coffee, and the capsule coffee can be filled into the capsule bin 191 through the through hole. The second surface of the capsule bin 191 has a liquid outlet 10 at an end opposite to the through hole, and the extracted coffee liquid can flow out through the liquid outlet 10. The liquid outlet 10 is the water outlet end of the coffee preparation module 190, and a user can place a cup at the bottom of the liquid outlet 10 to take out coffee.

The rocker 192 is sequentially connected with a pull rod 193, a rotating block 194, a connecting rod 195 and a pushing block 196 which are arranged in the cavity of the capsule bin 191, and when the rocker 192 rotates, the pull rod 193, the rotating block 194, the connecting rod 195 and the pushing block 196 are driven to move in the cavity, for example, move relatively in translation, rotation and the like. Fig. 4 is a schematic structural view of the capsule coffee preparation module when the rocker 192 is rotated to the first position in one embodiment of the present disclosure, and when the rocker 192 is rotated to the first position, the pull rod 193, the rotating block 194, the connecting rod 195 and the pushing block 196 are moved to an end of the cavity adjacent to the rocker 192 under the driving of the rocker 192. At this time, the capsule coffee may be placed in the capsule bin 191 through the through-hole. Rotating rocker 192, push block 196 will move within the pocket. The push block 196 has a cavity and a side opening through which the capsule coffee may enter the cavity within the push block 196. One side of the push block 196 away from the opening is connected with a connecting rod 195, and an inserting sheet 197 is arranged on one side of the push block 196 adjacent to the connecting rod 195.

Fig. 5 is a schematic structural diagram of a capsule coffee preparation module when a rocker is rotated to drive a push block to move in one embodiment of the disclosure, when the rocker 192 is rotated, the push block 196 will move towards an end far away from the rocker 192 under the drive of the rocker 192, capsule coffee will be gradually contained in a cavity of the push block 196, and an insert 197 in the push block 196 will pierce the tail of the capsule coffee. A baffle 198 is also arranged in the cavity of the capsule bin 191, and the baffle 198 is arranged opposite to the inserting sheet 197. When rocker 192 is rotated to the second position, as shown in fig. 3, capsule coffee is fully seated in push block 196 with tab 197 piercing the tail of capsule coffee and flap 198 abutting the top of capsule coffee.

The bottom surface of ejector pad 196 is equipped with water inlet 20 with the just opposite one end of inserted sheet 197, and water inlet 20 is connected with second water pump 180. Under the action of the second water pump 180, hot water in the coffee brewing water tank 170 is pumped into the capsule coffee preparation module, enters the capsule bin 191 through the water inlet 20, and enters the capsule coffee through the hole pierced by the insert 197, so that the brewing process of the coffee is completed, and coffee liquid can flow into the water cup of the user through the liquid outlet 10. The outlet 10 may be the outlet end of the coffee preparation module 190, i.e. may also be the second outlet of the coffee machine, through which outlet 10 a user may obtain a coffee beverage.

Fig. 6 is a schematic structural diagram of a baffle in one embodiment of the present disclosure, where the baffle 198 has a first surface and a second surface, the first surface has a plurality of boss portions 30, and bottoms of two adjacent boss portions 30 are connected by a groove. The flap 198 also includes a plurality of apertures 40 extending through the first and second faces. The top of the capsule coffee is typically sealed with an aluminum foil material. When hot water enters the capsule through the tail of the capsule coffee, the aluminum foil material is broken by expansion under the interaction of the water pressure in the capsule and the uneven surface of the first surface of the baffle 198 due to the limited extensibility of the aluminum foil material. The baffle 198 and the push block 196 provide a high pressure closed environment, and under the conditions of high pressure and high temperature, the coffee powder in the capsule coffee can be better extracted, so that a better coffee brewing effect is realized. The extracted coffee may collect on the second side through the holes 40 in the flap 198 and exit through the outlet 10.

Fig. 7 is a schematic view of a capsule coffee preparation module upon completion of brewing in one embodiment of the present disclosure, in some embodiments a capsule box may be provided at the bottom of the capsule bin 191, which may be used to contain spent capsule coffee. After coffee brewing is completed, rocker 192 may again be rotated to the first position. The pull rod 193, the rotating block 194, the connecting rod 195 and the pushing block 196 are driven by the rocker 192 to move to one end of the cavity close to the rocker 192. The support of the pushing block 196 is not provided, and the discarded capsule coffee falls down into the capsule box, so that the concentrated storage of the waste materials is realized, and a user can intensively clean the beverage brewing consumable.

As shown in the dashed-line frame structure of FIG. 7, in one embodiment, a preset clamping position 199 is provided at the end of the capsule bin 191 opposite to the through hole. The preset clamping position 199 is an inclined chute, and can limit the position of the capsule coffee. When the capsule coffee is filled into the capsule bin 191, the top of the capsule coffee can slide into the capsule bin 191 obliquely under the limit of the preset clamping position 199 and be clamped at a fixed position obliquely, so that the capsule coffee can be prevented from falling from the through hole directly. When the push block 196 moves to the position of the coffee capsule under the drive of the rocker 192, the position of the capsule will return to the normal position under the limiting action of the cavity in the push block 196. Therefore, when brewing is completed, the capsule moves backward under the driving of the rocker 192, and the preset clamping position 199 cannot continuously clamp the capsule because the position of the capsule is already right, so that the capsule falls down into the capsule box. According to the coffee purifying and drinking machine, the preset clamping position 199 is arranged in the capsule bin 191, so that the capsule coffee can be limited and fixed, the capsule coffee is prevented from falling off when being placed to influence the subsequent brewing process, and the preparation process and the preparation effect of the coffee preparation module 190 are further optimized.

In one embodiment, the flow rate of the first water pump 150 is greater than the flow rate of the second water pump 180. In some embodiments of the present disclosure, the first water pump 150 may be a 12V water pump and the second water pump 180 may be a 24V water pump. By having the flow of the first water pump 150 greater than the flow of the second water pump 180, it is ensured that the flow of hot water into the coffee brewing water tank 170 is greater than the flow of hot water out of the coffee brewing water tank 170, preventing the preparation flow of the coffee preparation module 190 from being affected by the interruption of the hot water supply, and reducing the waiting time of the user, thereby optimizing the user experience.

In one embodiment, as the living standard of people increases, the water quality requirements of users for drinking water are also increasing. The purity of the water is improved, and better use experience can be provided for users. Accordingly, the coffee beverage purifier provided by the present disclosure may further include a water purification module 100, and the water purification module 100 is utilized to provide higher quality drinking water. The water purification module 100 may be used to treat raw water to obtain purified water that meets the water demands of users. In some embodiments, the raw water may be tap water, mineral water, or the like. The water outlet end of the water purifying module 100 is connected with the water supply tank 110, and purified water obtained through treatment of the water purifying module 100 can be transmitted to the water supply tank 110 for storage, so that a subsequent user can flexibly take the purified water.

Fig. 2 is a schematic view illustrating a structure of a water purification module according to one embodiment of the present disclosure, and the water purification module 100 may include a raw water tank 220, a booster pump 230, a flushing solenoid valve 240, and a filtering unit 250. The raw water tank 220 may be used to store raw water, which may be tap water, spring water, or the like, which is not purified by the water purification module 100. The raw water tank 220 is connected with the filter unit 250 through the booster pump 230, the raw water tank 220 is also connected with the filter unit 250 through the flushing solenoid valve 240, and the water outlet end of the filter unit 250 is connected with the water supply tank 110.

The raw water in the raw water tank 220 may be pumped to the filtering unit 250 by the booster pump 230. One or more groups of filter elements can be arranged in the filtering unit 250 to filter raw water, and purified water obtained after the filtering can be transmitted to the water supply tank 110 for storage through the water outlet end of the filtering unit 250. The water discharged together with a part of the water after the impurities present in the raw water are filtered by the filtering unit 250 is concentrated water, which can be understood as waste water, but the waste water can be recycled. Under the action of the flushing solenoid valve 240, the concentrated water discharged from the filtering unit 250 can be pumped into the original water tank 220 again, waiting for the filtering treatment again, so as to fully utilize the water resource.

In one embodiment, as shown in fig. 2, the filter unit 250 may include a first filter element 251, a second filter element 252, and a third filter element 253. The water inlet end of the first filter element 251 is connected with the booster pump 230, the water outlet end of the first filter element 251 is connected with the water inlet end of the second filter element 252, the first water outlet end of the second filter element 252 is connected with the flushing solenoid valve 240, the second water outlet end of the second filter element 252 is connected with the water inlet end of the third filter element 253, and the water outlet end of the third filter element 253 is connected with the water supply tank 110. In one embodiment, the first filter element 251 is a polypropylene activated carbon composite filter element, the second filter element 252 is a reverse osmosis membrane filter element, and the third filter element 253 is an activated carbon filter element.

The polypropylene filter element is a common filtering device in a water purifier and can be used for filtering fine solid particle impurities in water. The active carbon filter element is also a common filter device, can be used for adsorbing chemical substances in water, and has the functions of decoloring, deodorizing, improving water quality and the like. Therefore, the polypropylene activated carbon composite filter element has good stain filtering effect. Raw water enters the first filter element 251 through the water inlet end of the first filter element 251 for preliminary filtration, and large-particle impurities in the raw water can be removed by using the polypropylene activated carbon composite filter element as the first filter element 251. The primarily filtered raw water may be transferred to the water inlet end of the second filter element 252 through the water outlet end of the first filter element 251.

Reverse osmosis is a membrane separation filtration technology that uses osmotic pressure differential as a motive force. By utilizing the selective permeability of the reverse osmosis membrane, only a solvent (usually water) can pass through the reverse osmosis membrane filter core, so that impurities such as ionic substances or micromolecular substances can be trapped. The static pressure on the two sides of the membrane is used as the driving force to realize the separation of the liquid mixture. The reverse osmosis membrane filter core can remove metal salt, organic matters, bacteria, colloid particles, heating substances and other ions dissolved in water. After the primarily filtered raw water passes through the water inlet end of the second filter element 252, the ion impurities soluble in water can be further removed by using a reverse osmosis membrane filter element as the second filter element 252. The liquid containing impurities such as ionic substances or small molecular substances flows out through the first water outlet end of the filter element, and the impurity liquid is pumped back into the raw water tank 220 under the action of the flushing solenoid valve 240. Raw water passing through the reverse osmosis membrane cartridge may be transferred to the water inlet end of the third cartridge 253 through the second water outlet end of the second cartridge 252.

The activated carbon filter element has good adsorption effect, and impurities such as residual chlorine, peculiar smell, color, chemical pollutants and the like in water are removed, so that the taste of the water is improved, and the water is more sweet. Therefore, after the secondary filtered raw water enters the third filter element 253 through the water outlet end of the third filter element 253, the quality of water can be improved by using the activated carbon filter element as the third filter element 253, and the drinking water experience of a user is optimized. The purified water treated by the third filter 253 may flow to the water supply tank 110 through the water outlet end of the third filter 253 to be stored.

The coffee purifying and drinking machine provided by the disclosure can effectively improve water quality and optimize product use experience of users by utilizing the water purifying module 100.
