Description

Technical Field

[0001] The present invention relates to the technical field of automatic coffee machines, in particular to a one-button thick milk latte coffee machine. Background Art

[0002] With the rapid evolution of automated beverage production equipment, the market is placing increasingly stringent demands on the breadth of functionality, operational precision, and food safety of automated coffee machines. Core demands have expanded from single-cup hot espresso production to encompass the processing of basic ingredients such as cold / hot milk froth, cold / hot milk, and cold / hot concentrate, as well as the full automation of complex beverages like one-touch whipped cheese lattes and one-touch iced fruit coffee. This requires equipment with comprehensive capabilities, including multi-ingredient adaptability, dual hot and cold system coordination, and end-to-end cleaning.

[0003] From the existing technology, the most similar automated equipment to the present invention is mainly traditional milk frothers and simple coffee machines, but their technical architecture has significant limitations and cannot meet the above requirements: In terms of hot and cold function coverage, existing equipment is stuck in the dilemma of "single hot function and lack of cold function". The core design of this type of equipment revolves around hot beverage scenarios, and its liquid delivery and processing logic is highly dependent on a single heating module - the milk is heated by a 220-240V heating wire, and a simple gas injection device is used to complete the hot milk foaming. It can only achieve the basic production of hot milk and hot milk foam. However, in response to cold processing needs, existing equipment lacks special technical support: the output of cold milk needs to rely on external pre-cooling equipment, and it is impossible to achieve stable delivery of low-temperature liquids through its own pipelines; the production of cold milk foam is even more difficult to break through the technical bottlenecks of high viscosity of cold liquids and poor bubble stability due to the lack of a whipping structure suitable for low-temperature environments. As a result, the cold milk foam has a rough texture and is easy to defoam, and cannot be included in the automated production system, which directly limits the automation of cold drinks such as cold brew latte and iced milk foam American.

[0004] Existing equipment, limited by its pipeline design, is stuck in a deadlock of single-product reliance and complex recipe constraints. These typically have only one or two inlet lines, coupled with simplified electromagnet control logic, supporting only one or two single dairy products, such as pure milk. They are incompatible with the automated switching of three or more ingredients, such as fresh milk, coconut milk, and thickened milk. This makes it difficult to accurately mix and deliver ingredients through the equipment's own pipelines for complex drinks like whipped cream lattes (which require thickened milk and hot concentrate) and iced fruit coffee (which requires coconut milk and cold concentrate). This forces the production of these drinks to be split across multiple devices, as the ingredients cannot be precisely proportioned and delivered through the equipment's own pipelines. This disrupts the automated closed-loop "one-click production" process and leads to mixing errors caused by the transfer of ingredients between devices, seriously impacting the standardization of the beverage's flavor.

[0005] Existing equipment lacks functionality for temperature control of concentrates. The hot or cold state of the concentrate (cold concentrate for cold drinks, hot concentrate for hot drinks) is crucial to the taste of the beverage, but existing equipment lacks a corresponding temperature control module. There's neither a heating structure like a "preheating boiler" (heating the liquid in hot water via a preheating coil) to raise the temperature of the concentrate, nor a cooling circuit design to preserve the concentrate at low temperatures. Consequently, hot concentrates must be preheated externally before being manually introduced. This process not only disrupts the automated process but also risks manual operation causing the temperature to deviate from the preset value (e.g., overheating can damage the concentrate's flavor), reducing product quality stability.

[0006] In terms of food hygiene and safety, existing equipment is severely lacking in cleaning mechanisms. After production, the equipment can only be emptied through simple pipes, without a hot water rinse for intermediate cleaning. Daily cleaning also lacks a chemical rinse (using a direct-flow electromagnet and a three-way valve to control the flow of chemical) and a subsequent hot water secondary rinse. As a result, after frequent use and switching between multiple ingredients, residual milk stains and concentrate residues in the pipes cannot be completely removed. This can cause flavor transfer between different drinks (such as coconut milk residue affecting the flavor of fresh milk) and can also breed bacteria, failing to meet the core food safety control requirements of automated equipment.

[0007] In summary, the technical shortcomings of existing automated equipment in areas such as hot and cold function integration, multi-ingredient adaptation, concentrate temperature control, and automated cleaning have become core bottlenecks hindering the realization of "one-click production for all product categories, full process standardization, and comprehensive food safety assurance." Against this backdrop, the development of a "one-click thick latte machine" with a multi-pipeline design, coordinated hot and cold systems, and a comprehensive cleaning process has become an inevitable trend in the functional upgrade of automated coffee machines. Summary of the Invention

[0008] In response to the above problems, the purpose of the present invention is to provide a one-touch thick milk latte coffee machine that can make a variety of drinks such as cold milk foam, hot milk foam, cold milk, hot milk, cold concentrate, hot concentrate, one-touch raw cheese latte, one-touch iced fruit coffee, etc., supports the use of a variety of dairy products and concentrates, and meets food safety requirements through milk path cleaning, reverse push and other processes.

[0009] The above-mentioned object of the present invention is achieved through the following technical solutions: A one-button thick milk latte coffee machine, comprising: a liquid input module, a liquid control module and a liquid output module; The liquid input module includes several independent liquid inlet pipelines, different of which are used to accommodate different liquids. The liquid control module is connected to the several independent liquid inlet pipelines through a drain valve. By controlling the on and off of the electromagnet on the drain valve, the on and off of the liquid inlet pipelines are switched to decide which liquid in the liquid inlet pipeline to use. The liquid output module is connected to the output port of the liquid control module to process the liquid flowing into the liquid output module and output it directly.

[0010] Furthermore, the liquid output module includes a preheater and a hot drink pipeline; When making hot drinks, the liquid is output from the liquid control module, passes through the outlet of the first three-way valve, and flows into the preheater through the hot drink pipe for heating. After heating, the liquid is directly output or output after frothing milk. The preheater comprises a heating wire, a preheating coil, a water holding chamber, a cold water inlet, and a hot water outlet; The cold water inlet is used for preheating the water chamber, injecting cold water to form an initial heating medium during startup and initialization, or automatically replenishing water when the water level in the water chamber drops to a threshold due to factors including evaporation and heat loss to maintain heat exchange capacity, or during the water replacement process in the water chamber, emptying the old water and injecting new cold water to refresh the medium; The hot water outlet is used for draining the water chamber, discharging the water in the water chamber during equipment maintenance or regular water changes, or outputting hot water from the water chamber to disinfect auxiliary pipelines during deep cleaning, or discharging residual liquid after cleaning, or discharging excess water when the water level in the water chamber exceeds the limit; The heating wire heats the water in the water holding chamber to a set temperature. When making hot drinks, the liquid enters from the liquid inlet of the preset coil, flows along the preset coil in the hot water of the preheater, and exits from the liquid outlet of the preset coil.

[0011] Furthermore, the liquid output module includes a cold drink pipeline; When making cold drinks, the liquid is output from the liquid control module through the second outlet of the first three-way valve and then passes through the cold drink pipe and is then directly output or is output after frothing milk; When the cold drink is directly output, it flows directly into the liquid outlet through the outlet 1 of the second three-way valve. When the milk foam needs to be frothed before output, it flows out through the outlet 2 of the second three-way valve for frothing and then flows into the liquid outlet.

[0012] Furthermore, the liquid output module includes a milk frother; The milk frother includes a base, a housing, and a spiral rotor. The milk frother is connected to a second gas input structure. Liquid, including hot or cold drinks, enters the milk frother through an inlet. The second gas input structure inputs gas into the milk frother, and the spiral rotor rotates at high speed to froth the liquid mixed with gas at high speed. The spiral rotor is provided with spiral grooves and spiral teeth. During the milk frothing process, the spiral grooves push the liquid toward the outlet of the milk frother, and the spiral teeth froth the milk.

[0013] Furthermore, it also includes a cleaning module; The cleaning module performs the following cleaning process: after the hot or cold drink is made or during the intermediate interval, the electromagnet of the drain valve is controlled to be on and off to close all the liquid inlet pipelines and open the emptying passage, and the gas input by the first gas input structure is controlled by the third three-way valve to drive the residual liquid in the emptying pipeline, and then the hot water cleaning passage is started to flush the pipeline with hot water, and then the pipeline is emptied again after flushing; during daily cleaning, the medicine passage is started, and the medicine is controlled to flow through the pipeline through the straight-through electromagnet and the fourth three-way valve, and then the hot water cleaning and emptying process is performed again to ensure that there is no residue in the pipeline.

[0014] Furthermore, the exhaust valve includes a plurality of exhaust valve units corresponding to the liquid inlet pipelines, and an exhaust valve unit for performing a cleaning process, and each of the exhaust valve units includes an independent electromagnet and a valve core; When a certain liquid needs to be extracted, the corresponding electromagnet is energized, driving the valve core to move axially and open the liquid inlet channel to complete the extraction of the liquid in that channel. After the extraction is completed, the electromagnet is de-energized, and the valve core returns to its original position and closes under the action of elastic force or its own gravity, cutting off the passage of the liquid in that channel. When a cleaning process needs to be performed, the electromagnet of the exhaust valve unit corresponding to the cleaning process is energized to drive the valve core to axially displace, so that the cleaning liquid inlet is connected to the main passage of the exhaust valve, and the cleaning liquid enters the exhaust valve and the downstream pipeline. After cleaning is completed, the electromagnet of the exhaust valve unit corresponding to the cleaning process is de-energized, and the valve core is reset and closed, cutting off the cleaning liquid passage.

[0015] Furthermore, the three-way valves including the first three-way valve, the second three-way valve, the third three-way valve, and the fourth three-way valve are specifically: The three-way valve is an electromagnetically controlled three-way valve, comprising a valve body, a valve core and an electromagnet; The valve body of the three-way valve is provided with ports A, B and C, wherein port A is the main passage inlet, port B is the first branch outlet, and port C is the second branch outlet. The built-in valve core is used to switch the passages, and the electromagnet is connected to one side of the valve body to drive the valve core to operate; When the three-way valve is in the power-off state, the valve core maintains its initial position, so that the interface A and the interface B are always connected. When the three-way valve is in the power-on state, the electromagnet is energized to drive the valve core to move or rotate, so that the interface A and the interface C are switched to be always connected, thereby realizing automatic switching of the liquid delivery path.

[0016] Furthermore, it also includes a liquid delivery pump; The liquid delivery pump is a gear pump, which is arranged downstream of the liquid output module. The gear pump is driven by a stepper motor or a servo motor. The liquid delivery flow rate of the gear pump is changed by adjusting the speed of the stepper motor or servo motor to adapt to the delivery requirements of different liquids.

[0017] Furthermore, it also includes combining the one-touch thick milk latte coffee machine with an ice maker for joint use, specifically: The ice maker is integrated above or on the side of the one-touch thick milk latte coffee machine, an ice chute extends from the bottom of the ice maker, and the end of the ice chute is connected to the ice-liquid mixing outlet of the one-touch thick milk latte coffee machine; The ice-liquid mixing outlet is a coaxial composite structure, the central channel is an ice delivery port connected to the ice chute, and is surrounded by a plurality of liquid injection tubes connected to the cold drink pipeline of the one-touch thick milk latte coffee machine; When the user triggers the ice drink recipe button, the ice maker first starts the ice discharging program, and the ice cubes slide along the ice discharging chute to the ice cube delivery port and fall into the cup body; synchronously, the one-button thick milk latte coffee machine controls the liquid in the cold drink pipeline to be sprayed out from the surrounding liquid injection tube, so that the ice cubes and liquid are synchronously mixed in the cup, realizing one-button automatic production of ice drinks.

[0018] Furthermore, the invention also includes combining the one-touch thick milk latte coffee machine with other devices into an efficient collaborative system to realize a design of making a cup of coffee in 25 seconds, specifically: The efficient collaborative system includes: Cup drop unit: equipped with a cup dropper with several cup positions to realize automatic drop feeding of empty cups; Cup picking actuator: It includes a movable, rotating, and lifting cup picking hand and a horizontally extending movable slide. The cup picking hand moves linearly along the slide and has the freedom of rotation and lifting to grab / release the cup body; Functional module layout: along the displacement path of the movable slide, the capping module, the fruit tea machine head, the one-button thick milk latte machine body, and the ice maker are sequentially integrated, corresponding to the capping, fruit tea liquid injection, coffee / thick milk making, and ice cube output functions respectively; Cup storage unit: Two rotating cup retrieval positions are set up, each of which can store several cups, and the upper side of the cup position is integrated with a capping mechanism; The efficient collaborative system achieves the 25-second production timing logic as follows: The cup dropping unit releases the empty cup, and the movable, rotating, lifting cup picking arm synchronously catches the empty cup; The mobile slide drives the cup-taking hand to access multiple modules in parallel: if it is an iced drink, the cup-taking hand first moves to the bottom of the ice maker to receive ice cubes, and simultaneously triggers the one-button thick milk latte machine to make coffee / thick emulsion; if it is a fruit tea coffee, the fruit tea machine head simultaneously starts the fruit tea injection, and the waiting time is shortened by parallelizing the module actions; After each module completes the processing, the cup picking arm rotates and transfers the cup body to any rotating cup picking position, and the cup pressing mechanism at the cup position performs the capping action in conjunction; Through cup-taking path optimization including linear displacement of the slide + rotation / lifting coordination of the cup-taking hand, parallel scheduling of module actions, and integration of capping and cup position storage, the full process production time of a single cup of beverage from cup placement to capping is achieved in 25 seconds or less.

[0019] Compared with the prior art, the present invention has at least one of the following beneficial effects: (1) The present invention can realize the production of a variety of drinks, including cold milk foam, hot milk foam, cold milk, hot milk, cold condensed milk, hot condensed milk, as well as one-click raw cheese latte, one-click iced fruit coffee, etc., which fully covers the needs of hot and cold drinks and solves the problem that the existing technology is difficult to take into account the production of hot and cold milk foam and milk products.

[0020] (2) It supports the addition of three or more dairy products, such as standard milk, thick coconut milk, optional coconut water, etc. It can also extract different types of coffee concentrate extracts, breaking through the limitations of the limited types of raw materials added by existing milk frothers and meeting the production needs of compound beverages.

[0021] (3) The milk frother adopts a purely physical frothing method. The spiral rotor rotates at high speed, and the spiral groove pushes the liquid and the spiral teeth froth the milk. It has low temperature requirements and can produce both hot milk foam and cold milk foam stably. Compared with traditional steam frothing, it has a wider range of applications and can also be used to make innovative drinks such as air hot American coffee and cold nitrogen American coffee.

[0022] (4) A complete pipeline cleaning process is integrated, including emptying and hot water cleaning after production, intermediate interval cleaning, and daily chemical cleaning. Through the milk line cleaning and reverse push process, pipeline residues are effectively avoided to meet food hygiene and safety requirements.

[0023] (5) It can be used in combination with an ice maker. When making ice drinks, the recipe button can be used to complete the process. The ice cubes are mixed with the liquid at the ice-liquid mixing outlet through the ice chute, which simplifies the ice drink making process and improves the convenience of operation.

[0024] (6) The efficient production of a cup of coffee within 25 seconds is achieved. By optimizing the equipment structure and working sequence, such as multi-module parallel operation and cup-taking path optimization, the production efficiency is greatly improved, which is suitable for high-frequency usage scenarios.

[0025] (7) The device comes standard with three liquid outlets and supports a variety of options, which can flexibly adapt to different beverage output requirements and enhance the versatility and scalability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Those skilled in the art will appreciate that, unless otherwise stated, the singular forms "a," "an," "said," and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present invention refers to the presence of the stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0029] First embodiment like Figure 1 As shown, this embodiment provides a one-button thick milk latte coffee machine, including: a liquid input module, a liquid control module and a liquid output module; The liquid input module includes several independent liquid inlet pipelines, different of which are used to accommodate different liquids. The liquid control module is connected to the several independent liquid inlet pipelines through a drain valve. By controlling the on and off of the electromagnet on the drain valve, the on and off of the liquid inlet pipelines are switched to decide which liquid in the liquid inlet pipeline to use. The liquid output module is connected to the output port of the liquid control module to process the liquid flowing into the liquid output module and output it directly.

[0030] The primary protection point of this invention is that it can control three or more liquid inputs, such as milk, coconut milk, and tea, through the control of multiple three-way valves. Its core structure achieves automated control of beverage production through three modules: the liquid input module is equipped with several independent liquid inlet lines, each capable of accommodating different liquids such as milk, coconut milk, and coffee concentrate, meeting the needs of adapting to multiple ingredients. This is consistent with the design of increasing the number of inlet lines to enable the production of a variety of dairy products and concentrates. The liquid control module, serving as the core control unit, is connected to each liquid inlet line through a discharge valve. The electromagnet on the discharge valve controls the opening and closing of the valve core, thereby switching the opening and closing of different liquid inlet lines to select the use of a specific liquid. This logic is consistent with the operating principle of the discharge valve: the electromagnet opens the valve core when it is energized to extract liquid, and closes the valve core when it is deenergized. The liquid output module receives liquid from the control module and processes it according to the beverage requirements, such as heating and frothing, before outputting it directly. This covers the functions of hot beverage production through a preheater and cold beverage and milk frothing production through corresponding pipeline switching.

[0031] Furthermore, the liquid output module includes a preheater and a hot drink pipeline; When making hot drinks, the liquid is output from the liquid control module through the outlet of the first three-way valve and then flows into the preheater through the hot drink pipe for heating. After heating, the liquid is directly output or output after frothing milk. Figure 1 The middle row valve controls the 2-4 solenoid valves to determine which liquid to use. The gear pump (or peristaltic pump) works. When making hot drinks, it passes through the preheater. When frothing milk, it passes through the milk frother and the gas 2 of the second gas input structure enters for frothing. If frothing is not needed, the milk frother and gas 2 do not need to be started.

[0032] like Figure 2 The preheater comprises a heating wire, a preheating coil, a water holding chamber, a cold water inlet, and a hot water outlet; The cold water inlet is used for preheating the water chamber, injecting cold water to form an initial heating medium during startup and initialization, or automatically replenishing water when the water level in the water chamber drops to a threshold due to factors including evaporation and heat loss to maintain heat exchange capacity, or during the water replacement process in the water chamber, emptying the old water and injecting new cold water to refresh the medium; The hot water outlet is used for draining the water chamber, discharging the water in the water chamber during equipment maintenance or regular water changes, or outputting hot water from the water chamber to disinfect auxiliary pipelines during deep cleaning, or discharging residual liquid after cleaning, or discharging excess water when the water level in the water chamber exceeds the limit; The heating wire heats the water in the water holding chamber to a set temperature. When making hot drinks, the liquid enters from the liquid inlet of the preset coil, flows along the preset coil in the hot water of the preheater, and exits from the liquid outlet of the preset coil.

[0033] like Figure 2 The core components and working logic of the preheater structure shown are designed around the needs of heat exchange: the heating wire, preheating coil, and water chamber constitute the heat exchange core, while the cold water inlet and hot water outlet are responsible for the medium supply and discharge of the water chamber, respectively. The cold water inlet is designed specifically for water replenishment in the water chamber. Cold water is injected during startup initialization to build the initial heating medium. When the water level in the water chamber falls below the threshold due to evaporation, heat loss, etc., it automatically replenishes water to maintain heat exchange capacity, or during the water change process, new cold water is injected after the old water is drained to update the medium. This is consistent with the basic logic that the preheating boiler must first be filled with water and heated by the heating wire. The hot water outlet is used to drain the water chamber, including draining the water in the chamber during equipment maintenance or regular water changes, outputting hot water to disinfect the auxiliary pipeline during deep cleaning, discharging residual liquid after cleaning, or discharging excess water when the water level exceeds the limit, to ensure safe and stable operation of the water chamber. The function of the heating wire is to heat the water in the water chamber to the set temperature. When making hot drinks, the liquid enters from the inlet of the preheating coil, flows along the coil in the hot water in the water chamber, and flows out from the outlet after being heated through heat exchange. This process directly reflects the working principle of the preheating coil using the hot water in the water chamber to heat the liquid.

[0034] Furthermore, the liquid output module includes a cold drink pipeline; When making cold drinks, the liquid is output from the liquid control module through the second outlet of the first three-way valve and then through the cold drink pipe and then directly output or output after frothing the milk; Figure 1 When making cold drinks, the second three-way valve is used. When making cold milk froth, the second three-way valve is switched, and gas 2 from the second gas input structure enters to froth the cold milk. If froth is not required, the gas flows directly out of the liquid outlet.

[0035] When the cold drink is directly output, it flows directly into the liquid outlet through the outlet 1 of the second three-way valve. When the milk foam needs to be frothed before output, it flows out through the outlet 2 of the second three-way valve for frothing and then flows into the liquid outlet.

[0036] Furthermore, the liquid output module includes a milk frother; like Figure 3As shown in the schematic diagram of a milk frother, the milk frother includes a base, a housing, and a spiral rotor. The milk frother is connected to a second gas input structure. Liquid, including hot or cold drinks, enters the milk frother through its inlet. The second gas input structure inputs gas into the milk frother, and the spiral rotor rotates at high speed to froth the liquid mixed with gas at high speed. The spiral rotor is provided with spiral grooves and spiral teeth. During the frothing process, the spiral grooves push the liquid toward the outlet of the milk frother, and the spiral teeth froth the milk.

[0037] like Figure 3 The structure and operating principle of the milk frother shown are designed around pure physical whipping. Its core consists of a base, a housing, and a spiral rotor, which is consistent with the description of the main components of a milk frother. During operation, whether it is a hot or cold drink, liquid enters the milk frother through the inlet, while a secondary gas input structure simultaneously feeds gas into it. The spiral rotor rotates at high speed, using its own spiral grooves to push the gas-mixed liquid toward the outlet. Simultaneously, the spiral teeth whip the liquid at high speed to form milk foam, fully demonstrating the synergistic effect of the spiral rotor's spiral grooves and teeth in achieving liquid pushing and milk foaming. This purely physical whipping method has low temperature requirements and is suitable for both hot drink milk foaming and cold milk foaming. This distinguishes it from traditional steam whipping methods and can also be expanded to the preparation of drinks such as air-heated Americano and cold nitrogen Americano.

[0038] Furthermore, the one-button thick milk latte coffee machine of this embodiment further includes a cleaning module; The cleaning module performs the following cleaning process: after the hot or cold drink is made or during the intermediate interval, the electromagnet of the drain valve is controlled to be on and off to close all the liquid inlet pipelines and open the emptying passage, and the gas input by the first gas input structure is controlled by the third three-way valve to drive the residual liquid in the emptying pipeline, and then the hot water cleaning passage is started to flush the pipeline with hot water, and then the pipeline is emptied again after flushing; during daily cleaning, the medicine passage is started, and the medicine is controlled to flow through the pipeline through the straight-through electromagnet and the fourth three-way valve, and then the hot water cleaning and emptying process is performed again to ensure that there is no residue in the pipeline.

[0039] In this embodiment, the cleaning module full process analysis (1) Hot drink pipeline cleaning sub-process (precisely covering hot milk, hot coffee, etc. residues) 1. Emptying of hot beverage residue (pneumatic purge stage) Trigger condition: Executed immediately after a hot drink is dispensed, or automatically triggered when the device is in standby for more than 30 minutes.

[0040] Component linkage details: Power layer: The first gas input (gas 1, 0.4MPa clean air) is started, and the gear pump rotates forward at low speed (1500rpm), forming a dual power of "air pressure pushing + pump pressure pushing", forcibly expelling viscous residues (such as hot milk foam fat and coffee oil) in the hot drink pipeline.

[0041] Pathway layer: The solenoid in exhaust valve 1 is energized, cutting off the flow of ingredients such as milk and thick coconut milk; the first three-way valve is energized, switching to the main hot drink flow (connection A to connection C); the spiral rotor of the milk frother starts synchronously, and gas 2 injects air into the milk frother to ensure that any residual spiral grooves and tooth gaps are flushed away by the airflow (all components are "started and closed at the same time" to prevent leakage of the milk frother cavity).

[0042] Core purpose: To eliminate the risk of "time difference breeding bacteria" caused by heat residue and reserve a clean pipeline for the next cup of hot drink.

[0043] 2. Rinse with hot water (physical flushing + high temperature disinfection) Hot water source: The water chamber of the preheater is heated to 85°C by the heating wire (using the "hot water outlet auxiliary disinfection" function to simultaneously meet the high-temperature medium requirements for equipment maintenance and water changes).

[0044] Component linkage details: Path switching: The third three-way valve is energized to connect hot water to the water storage chamber; the drain valve 1, gear pump, first three-way valve, gas 2, and milk frother continue to "open and close together", forming a closed-loop path of "drain valve 1 → hot drink tube → milk frother → liquid outlet".

[0045] Enhanced flushing: The gear pump is set to high forward speed (3000rpm) to create turbulent flow of 85℃ hot water, flushing caramelized milk stains and coffee residues on the inner wall of the pipeline; the milk frother spiral rotor runs in the reverse direction (-3000rpm) to forcibly clean the residual dead corners on the back side of the spiral teeth.

[0046] Core purpose: Through "high temperature physical scouring + turbulent disturbance", the chemical adhesion of heat residues is broken down and thermophilic bacteria (such as Streptococcus) are killed.

[0047] 3. Empty after hot drink flushing (secondary pneumatic purge) Component linkage: Reuses the emptying logic of "gas 1 + exhaust valve 1 + gear pump (low-speed reverse, auxiliary withdrawal) + first three-way valve 1 + gas 2 + milk frother", focusing on removing hot water residue in the spiral structure of the milk frother to prevent water accumulation and bacterial growth.

[0048] (2) Cold drink pipeline cleaning sub-process (targeted treatment of cold milk, ice concentrate, etc. residues) 1. Emptying of cold drink residue (pneumatic purge stage) Trigger condition: Executed immediately after a cold drink is dispensed, or automatically triggered when the device is in standby for more than 30 minutes.

[0049] Component linkage differences: Path switching: The second three-way valve 2 is energized and switched to the cold drink main path (interface A→interface C is connected), covering the residual pipelines such as cold milk, ice concentrate, and cold coconut milk foam.

[0050] Power adaptation: The gear pump adopts an "intermittent start-stop" mode (start 1 second → pause 0.5 seconds), using liquid inertia to discharge low-viscosity residues (such as ice milk and cold concentrate) in the cold drink pipeline; the milk frother spiral rotor rotates synchronously in the forward direction, and the gas 2 is used to flush ice crystals from the gaps in the spiral groove.

[0051] Key breakthrough: Solving the problem of cold residue easily freezing in the spiral structure of the milk frother by forcibly breaking up ice crystals through "pump pressure inertia + rotor agitation".

[0052] 2. Cold and hot water rinse (thermal penetration disinfection + physical descaling) Source of hot water: Same as the hot drink process (85℃ hot water in the preheater), using the thermal osmotic effect to kill psychrophilic bacteria (such as Listeria) on the inner wall of the cold drink pipeline.

[0053] Component linkage details: Path switching: The third three-way valve is energized, and the second three-way valve is energized to build a closed-loop path of "exhaust valve 1 → cold drink pipe → milk frother → liquid outlet".

[0054] Flushing optimization: The gear pump adopts the "forward and reverse alternating" mode (forward rotation 2000rpm → reverse rotation 1500rpm), so that the hot water forms a vortex in the cold drink pipeline, focusing on cleaning the cold fat residue on the back side of the spiral teeth of the milk frother.

[0055] Core purpose: Eliminate cold residual microbial films (such as E. coli in biofilms) through "high temperature thermal penetration + eddy current disturbance".

[0056] 3. Empty after cold drink rinsing (secondary pneumatic purging) Component linkage: Reuse the emptying logic of "gas 1 + exhaust valve 1 + gear pump (low-speed forward rotation, auxiliary push) + second three-way valve 2 + gas 2 + milk frother" to focus on removing residual condensate in the cold drink pipeline to avoid pipeline corrosion caused by alternating hot and cold temperatures.

[0057] (3) Chemical disinfection and cleaning process (periodic chemical attack, must be performed every day) 1. Channel construction: hot drink + cold drink dual-channel parallel disinfection Main circuit conduction: The straight-through solenoid valve is energized and connected to food-grade disinfectant (such as acidic oxidizing potential water, pH ≤ 2.7); The fourth three-way valve is energized to establish the main medicine channel; the third three-way valve is energized to distribute the medicine to the hot drink side (third three-way valve) and the cold drink side (second three-way valve), realizing dual-channel synchronous liquid supply.

[0058] Full path coverage: With drain valve 1 energized, the gear pump operates in an intermittent forward and reverse cycle (forward for 30 seconds → reverse for 10 seconds), driving the liquid to traverse: liquid inlet pipe → hot drink pipe → milk frother → cold drink pipe → liquid outlet, forcing the liquid to penetrate all gaps in the pipes (including the micron-level gaps between the spiral grooves / teeth of the milk frother).

[0059] 2. Cyclic disinfection: dual enhancement of time and power Circulation time: The solution circulates in the pipeline for 10 minutes to ensure that the chemical agent fully destroys the bacterial cell wall (such as the lipopolysaccharide layer of Gram-negative bacteria).

[0060] Power optimization: The gear pump speed is adjusted to 2500rpm to maximize the contact area between the solution and the pipeline through turbulence, thus conquering the stubborn bacteria clusters (such as Pseudomonas aeruginosa) in the core of the biofilm.

[0061] 3. Residue removal: dual-channel hot water + dual-channel emptying combination Synchronous triggering: After the medicine cycle is completed, the "hot drink hot water cleaning + hot drink emptying" and "cold drink hot water cleaning + cold drink emptying" are automatically started: Step 1: Rinse with 85°C hot water to remove any residual chemicals (to prevent chemicals from affecting the flavor of the drink, such as citric acid residue causing coffee to become sour); Step 2: Pneumatically blow out and empty the pipes to ensure they are dry (a dry environment can reduce the growth rate of bacteria by more than 80%).

[0062] (4) Technical barriers and value of cleaning modules The entire chain is seamless: from the raw material inlet to the liquid outlet, from the hot drink tube to the cold drink tube, and from the outer wall of the milk frother to the spiral tooth gap, 100% pipeline coverage is achieved, solving the hidden dangers of flavor cross-contamination when switching between multiple raw materials (such as thick coconut milk residue contaminating coffee).

[0063] Strong timing coordination: All components start and stop synchronously at the millisecond level, eliminating missed washes due to time differences in operation (e.g., delayed start-up of the milk frother, leaving residues in its cavity uncleaned and a breeding ground for bacteria).

[0064] Food safety closed loop: Constructing a five-layer protection system of "pneumatic emptying → hot water flushing → medicine circulation → secondary hot water → final emptying", strictly adapting to the "General Hygiene Standards for Food Production", and providing underlying support for the standardized and safe production of compound beverages such as "One-Click Thick Milk Latte".

[0065] Furthermore, if Figure 4As shown in the schematic diagram of the exhaust valve, the exhaust valve includes a plurality of exhaust valve units corresponding to the liquid inlet pipelines, and a exhaust valve unit for performing the cleaning process. Each exhaust valve unit includes an independent electromagnet and valve core. When a certain liquid needs to be extracted, the corresponding electromagnet is energized, driving the valve core to move axially and open the liquid inlet channel to complete the extraction of the liquid in that channel. After the extraction is completed, the electromagnet is de-energized, and the valve core returns to its original position and closes under the action of elastic force or its own gravity, cutting off the passage of the liquid in that channel. When a cleaning process needs to be performed, the electromagnet of the exhaust valve unit corresponding to the cleaning process is energized to drive the valve core to axially displace, so that the cleaning liquid inlet is connected to the main passage of the exhaust valve, and the cleaning liquid enters the exhaust valve and the downstream pipeline. After cleaning is completed, the electromagnet of the exhaust valve unit corresponding to the cleaning process is de-energized, and the valve core is reset and closed, cutting off the cleaning liquid passage.

[0066] The core design of the exhaust valve structure is built around "multi-channel independent control + dedicated cleaning channel". The precise linkage between the electromagnet and the valve core realizes the rigid isolation of liquid extraction and cleaning processes. The details are as follows: The drain valve consists of two types of drain valve units: one is a number of units corresponding to the liquid inlet pipelines (such as milk, thick coconut milk, coffee concentrate, etc.), and the other is an independent cleaning process dedicated unit. Each unit is equipped with an independent electromagnet and valve core to ensure that the channel switching does not interfere with each other.

[0067] When a certain liquid needs to be extracted, the electromagnet of the discharge valve unit of the corresponding liquid pipeline is energized, driving the valve core to move axially to open the liquid inlet channel, and the gear pump (or peristaltic pump) works synchronously to complete the extraction of the liquid in this line; after the extraction is completed, the electromagnet is de-energized, and the valve core returns to its original position and closes under the action of elastic force or its own gravity, completely cutting off the liquid passage and avoiding liquid cross-contamination. This action logic is consistent with the principle of "the electromagnet is energized to open the valve when extracting liquid, and the power is de-energized to close the valve when the extraction is completed."

[0068] When the cleaning process is executed, the electromagnet of the special exhaust valve unit for cleaning is energized separately, and the axial displacement of the valve core makes the cleaning liquid inlet and the main passage of the exhaust valve connected. Cleaning liquids such as hot water or medicine enter the exhaust valve and downstream pipelines (such as hot drink pipes, cold drink pipes, and milk frothers) through this passage. After the cleaning is completed, the electromagnet is de-energized, the valve core is reset and closed, cutting off the cleaning liquid passage, ensuring that the cleaning liquid and the raw material liquid passage are completely isolated, avoiding cleaning residues from contaminating the raw materials, and preventing the raw materials from entering the cleaning pipeline and affecting the cleaning effect.

[0069] This design, through the "one valve, multiple units, and independent control of each unit" structure, not only meets the independent input needs of more than three liquids (such as milk, coconut milk, and tea), but also provides a dedicated path for the cleaning process. It is a core component for achieving multi-raw material adaptation and food safety cleaning.

[0070] Furthermore, if Figure 5 As shown in the schematic diagram of the three-way valve structure, the three-way valve including the first three-way valve, the second three-way valve, the third three-way valve and the fourth three-way valve is specifically: The three-way valve is an electromagnetically controlled three-way valve, comprising a valve body, a valve core and an electromagnet; The valve body of the three-way valve is provided with ports A, B and C, wherein port A is the main passage inlet, port B is the first branch outlet, and port C is the second branch outlet. The built-in valve core is used to switch the passages, and the electromagnet is connected to one side of the valve body to drive the valve core to operate; When the three-way valve is in the power-off state, the valve core maintains its initial position, so that the interface A and the interface B are always connected. When the three-way valve is in the power-on state, the electromagnet is energized to drive the valve core to move or rotate, so that the interface A and the interface C are switched to be always connected, thereby realizing automatic switching of the liquid delivery path.

[0071] Furthermore, the one-button thick milk latte coffee machine also includes a liquid delivery pump; the liquid delivery pump is a gear pump, which is arranged downstream of the liquid output module. The gear pump is driven by a stepper motor or a servo motor. By adjusting the speed of the stepper motor or the servo motor to change the liquid delivery flow rate of the gear pump, it can adapt to the delivery requirements of different liquids.

[0072] Furthermore, if Figure 6 As shown in the schematic diagram of the coffee machine + ice maker combination, it also includes combining the one-button thick milk latte coffee machine with the ice maker for joint use, specifically: The ice maker is integrated above or on the side of the one-touch thick milk latte coffee machine, an ice chute extends from the bottom of the ice maker, and the end of the ice chute is connected to the ice-liquid mixing outlet of the one-touch thick milk latte coffee machine; The ice-liquid mixing outlet is a coaxial composite structure, the central channel is an ice delivery port connected to the ice chute, and is surrounded by a plurality of liquid injection tubes connected to the cold drink pipeline of the one-touch thick milk latte coffee machine; When the user triggers the ice drink recipe button, the ice maker first starts the ice discharging program, and the ice cubes slide along the ice discharging chute to the ice cube delivery port and fall into the cup body; synchronously, the one-button thick milk latte coffee machine controls the liquid in the cold drink pipeline to be sprayed out from the surrounding liquid injection tube, so that the ice cubes and liquid are synchronously mixed in the cup, realizing one-button automatic production of ice drinks.

[0073] like Figure 6The combined coffee machine and ice maker structure shown achieves efficient, automated production of iced drinks through an integrated design. Its core logic revolves around "structural adaptation + timing coordination": From a layout perspective, the ice maker is integrated above or on the side of the one-touch thick milk latte machine. The ice chute extending from the bottom precisely mates with the coffee machine's ice-liquid mixing outlet, forming a compact "ice making-ice dispensing-mixing" pathway. This design directly serves the need for continuous iced drink production. The ice-liquid mixing outlet adopts a coaxial composite structure, which is the key to achieving synchronous mixing of ice and liquid: the central channel is the ice delivery port, connected to the ice chute to ensure that the ice cubes can slide smoothly; several surrounding liquid injection tubes are connected to the coffee machine's cold drink pipeline, which can accurately output ingredients such as cold milk and cold concentrate. This structure avoids the problem of uneven mixing caused by the step-by-step addition of ice cubes and liquid. In terms of operating sequence, when the user triggers the ice drink recipe button, the ice maker first starts the ice dispensing process, with ice cubes sliding down the ice chute to the ice delivery port and falling into the cup. Simultaneously, the coffee machine controls the liquid in the cold drink pipeline to be sprayed out from the surrounding spray tubes, instantly mixing the ice cubes and liquid in the cup. This completes the ice drink preparation process without manual intervention, fully demonstrating the convenience of "one-click operation." This combined design breaks through the traditional step-by-step "ice first, then liquid" model of ice drink preparation. Through structural integration and timing coordination, it not only ensures the taste of the ice drink (the ice cubes are not over-melted) but also improves production efficiency, representing a targeted optimization for cold drink preparation scenarios.

[0074] Furthermore, if Figure 7 The design structure diagram of the 25-second cup of coffee also includes combining the one-touch thick milk latte coffee machine with other equipment into an efficient collaborative system to achieve a design of 25-second cup of coffee, specifically: The efficient collaborative system includes: Cup drop unit: equipped with a cup dropper with several cup positions to realize automatic drop feeding of empty cups; Cup picking actuator: It includes a movable, rotating, and lifting cup picking hand and a horizontally extending movable slide. The cup picking hand moves linearly along the slide and has the freedom of rotation and lifting to grab / release the cup body; Functional module layout: Along the displacement path of the movable slide, the capping module, the fruit tea machine head, the one-touch thick milk latte machine body (the location of the milk frother in the figure), and the ice maker are integrated in sequence, corresponding to the capping, fruit tea liquid injection, coffee / thick milk making, and ice cube output functions respectively; Cup storage unit: Two rotating cup retrieval positions are set up, each of which can store several cups, and the upper side of the cup position is integrated with a capping mechanism; The efficient collaborative system achieves the 25-second production timing logic as follows: The cup dropping unit releases the empty cup, and the movable, rotating, lifting cup picking arm synchronously catches the empty cup; The mobile slide drives the cup-taking hand to access multiple modules in parallel: if it is an iced drink, the cup-taking hand first moves to the bottom of the ice maker to receive ice cubes, and simultaneously triggers the one-button thick milk latte machine to make coffee / thick emulsion; if it is a fruit tea coffee, the fruit tea machine head simultaneously starts the fruit tea injection, and the waiting time is shortened by parallelizing the module actions; After each module completes the processing, the cup picking arm rotates and transfers the cup body to any rotating cup picking position, and the cup pressing mechanism at the cup position performs the capping action in conjunction; Through cup-taking path optimization including linear displacement of the slide + rotation / lifting coordination of the cup-taking hand, parallel scheduling of module actions, and integration of capping and cup position storage, the full process production time of a single cup of beverage from cup placement to capping is achieved in 25 seconds or less.

[0075] like Figure 7 The efficient collaborative system shown in the figure, which can produce a cup of coffee in 25 seconds, achieves rapid production through the design of "component integration + timing parallelization". The core logic revolves around "reducing waiting and optimizing paths": the system consists of four core units: the cup drop unit is equipped with a multi-cup cup channel cup dropper to realize the automatic supply of empty cups, without the need for manual cup placement; the movable rotating and lifting cup-taking arm of the cup-taking actuator cooperates with the horizontal moving slide, with three degrees of freedom of linear displacement, rotation, and lifting, which can flexibly grasp and transfer the cup body; the functional modules are arranged along the slide in sequence: the cap drop module, the fruit tea machine head, the one-button thick milk latte coffee machine body (corresponding to the position of the milk frother in the figure), and the ice maker, which are responsible for capping, fruit tea filling, coffee / thick milk making, and ice cube output, forming a "one-stop" processing chain; the cup position storage unit is equipped with two rotating cup positions, which can temporarily store cups and has an integrated capping mechanism to avoid time loss in the capping link. Timing coordination is key to achieving 25-second efficiency: After the cup dropper releases an empty cup, the cup picker simultaneously catches it, and the mobile slide drives it to access multiple modules in parallel. When making iced drinks, the cup picker first moves to the ice maker to collect ice, while simultaneously triggering the coffee machine to make coffee / thick emulsion, both of which are processed in parallel. When making fruit tea coffee, the fruit tea machine head starts filling liquid simultaneously, overlapping with the coffee machine's production process. After each module is completed, the cup picker rotates and transfers the cup to the rotating cup picker position, where the capping mechanism activates the capping mechanism. Through the path optimization of "slide linear movement + cup picker rotation / lifting coordination" and parallel scheduling of module actions, the entire process from cup drop to capping is ultimately achieved in ≤25 seconds. This design, through the compact layout of the mechanical structure and the precise coupling of action timing, transforms the traditional serial process into parallel processing, significantly reducing the single-cup production time and adapting to high-demand scenarios.

[0076] Second embodiment The one-touch thick milk latte coffee machine of the present invention can freely select specific structural types. It is not necessary to include all structures according to actual needs and cost budget. Specifically, it can include the following combinations: (1) Full-function model (supports cleaning + supports cold milk foam + supports hot milk) This one-touch thick milk latte machine is equipped with a complete cleaning module and a full-temperature zone milk frothing system: Cleaning support: After production is completed, the "gas exhaust → hot water flushing → secondary exhaust" process is automatically executed. The "chemical solution circulation + hot water cleaning + exhaust" combined cleaning is started every day. The exhaust valve switching and three-way valve control ensure that there is no residue in the pipeline. Cold milk froth support: The milk frother uses a spiral rotor structure. After the cold milk enters, it is reversed through the three-way valve 2 and gas 2 is introduced. The spiral rotor rotates at high speed, using the spiral groove to push the liquid and the spiral teeth to froth it, generating cold milk froth. Hot milk support: After the hot milk is selected by the discharge valve, it is heated to the set temperature by the preheating coil of the preheating boiler and can be directly output as hot milk or enter the milk frother, where gas 2 is introduced to make hot milk foam; Cold milk support: Cold milk enters the cold drink pipeline through solenoid valve 2 and flows out directly from the liquid outlet without being whipped, meeting the demand for direct drinking of cold milk.

[0077] (2) Basic function model (limited support for cleaning + support for cold milk foam + support for hot milk) This is a simplified version that retains core functions but simplifies the cleaning process: Cleaning support: Only supports gas emptying after production and hot water flushing in between. Daily cleaning with chemicals is not supported. Basic pipeline cleaning is achieved by opening drain valve 1 and starting gas 1 to meet simple food safety requirements. Cold milk foam support: Same as (1), relying on the physical whipping technology of the milk frother's spiral rotor to achieve cold milk foam production; Hot milk support: The water in the water container is heated by the preheating boiler heating wire, and the hot milk is output after being heated by the preheating coil, supporting the production of hot milk and hot milk foam; Cold milk support: Cold milk is delivered directly through the cold drink line without heating or frothing.

[0078] (3) Hot milk foam special version (supports cleaning + does not support cold milk foam + supports hot milk) This model is optimized for hot drink scenarios, omitting the cold milk foam function but retaining the full temperature range liquid output: Cleaning support: Configure a complete cleaning module, including gas emptying, hot water cleaning and daily chemical cleaning, consistent with (1); Cold milk foam support: does not support cold milk foaming. Cold milk is directly output through the cold drink pipeline (without foaming function), which only meets the needs of direct drinking of cold milk. Hot milk support: Hot milk can be directly discharged after preheating, or enter the milk frother and pass gas 2, and then be frothed by the spiral rotor, suitable for hot latte and other scenarios; Cold milk support: Cold milk enters the cold drink pipeline through the second three-way valve and flows out directly from the liquid outlet to ensure the supply of cold liquid.
