Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a beverage equipment device. Background Technology

[0002] Most existing coffee machines and beverages such as tea require hot water extraction to preserve their flavor. The extraction temperature requirements for tea and coffee, as well as for different types of tea, are different. For example, some coffees are usually extracted at a temperature of 85°C to 95°C, but some types of tea must be extracted at a lower temperature, such as around 70°C. However, some commercial coffee machines on the market cannot quickly adjust the extraction temperature, making it difficult to meet the diverse product preparation requirements of tea shops. Utility Model Content

[0003] Therefore, it is necessary to provide a beverage preparation device to address the problem that some commercial coffee machines on the market cannot quickly adjust the extraction temperature and thus cannot meet the diverse product preparation requirements of tea shops.

[0004] A beverage preparation apparatus includes: a hot water boiler having a liquid storage chamber and a liquid outlet communicating with the liquid storage chamber, the liquid outlet being used to discharge liquid from the liquid storage chamber; a first heating component disposed on the hot water boiler for heating the liquid in the liquid storage chamber; a water supply module including a cold water inlet pipe and a hot water inlet pipe, the cold water inlet pipe communicating with the liquid storage chamber and having a first pump assembly on the cold water inlet pipe to pump cold water into the liquid storage chamber, the hot water inlet pipe communicating with the liquid storage chamber and having a second pump assembly on the hot water inlet pipe to pump hot water into the liquid storage chamber; a control device for controlling the operation of the first heating component, the first pump assembly, and the second pump assembly to adjust the temperature of the liquid in the liquid storage chamber; and a water outlet pipe having an input end communicating with the liquid storage chamber to output the temperature-adjusted liquid.

[0005] This application provides a beverage preparation apparatus, including a hot water boiler, a first heating component, a cold water inlet pipe, a hot water inlet pipe, an outlet pipe, and a control device. The control device controls the operation of the first heating component, a first pump component on the cold water inlet pipe, and a second pump component on the hot water inlet pipe. On the one hand, it drives the first pump component to deliver cold water to the storage chamber, so that the exchange and mixing of hot and cold water takes place in the storage chamber, thereby quickly adjusting the temperature of the liquid in the hot water boiler. On the other hand, the operation of the first pump component and / or the second pump component can provide power for the output of the temperature-adjusted liquid in the storage chamber, thereby simplifying the water circuit structure of the beverage preparation apparatus. Specifically, when the beverage preparation device needs to perform high-temperature extraction, the first heating component can raise the temperature of the liquid in the storage chamber. When the liquid temperature reaches the set temperature value T1, the second pump component can be driven to deliver hot water into the storage chamber. This allows the temperature-adjusted liquid to be output through the water outlet while the liquid in the storage chamber remains at a high temperature, avoiding affecting the extraction effect. When the beverage preparation device needs to switch to low-temperature extraction, the first heating component will stop working. The first pump component will be driven to deliver cold water into the storage chamber to mix with the hot water inside, and the high-temperature water in the storage chamber will be discharged through the outlet. This can accelerate the adjustment of the mixing ratio of cold and hot water, thereby improving the cooling effect. When the liquid temperature reaches the set temperature value T2, the first pump component can be driven to deliver cold water into the storage chamber to drive the temperature-adjusted liquid to be output and keep the liquid in the storage chamber at a low temperature. Furthermore, when the extraction temperature of the beverage preparation device needs to be adjusted from T2 to T3 (T3 < T1), the first heating component can be driven to heat the liquid in the storage chamber to the set temperature value T3. At the same time, the first pump component and the second pump component are driven to work, so that when the temperature-adjusted liquid is output, cold water and hot water can be input into the storage chamber at the same time, which is conducive to maintaining the liquid temperature in a medium-high temperature state.

[0006] In one embodiment, the hot water boiler is provided with a first liquid inlet communicating with the liquid storage chamber, one end of the cold water inlet pipe is connected to a water source, and the other end of the cold water inlet pipe is connected to the liquid storage chamber through the first liquid inlet.

[0007] In one embodiment, the hot water boiler is provided with a second liquid inlet communicating with the liquid storage chamber, one end of the hot water inlet pipe is connected to a water source, and the other end of the hot water inlet pipe is connected to the liquid storage chamber through the second liquid inlet.

[0008] In one embodiment, a steam boiler and / or a water receiving tray are also included, with the liquid outlet connected to the steam boiler and / or the water receiving tray. By employing the above structure, when the beverage preparation apparatus switches from high-temperature extraction to low-temperature extraction, the liquid in the storage chamber can be discharged into the steam boiler through the liquid outlet. This rapidly reduces the high-temperature water content in the storage chamber, accelerates the adjustment of the mixing ratio of cold and hot water, and improves the cooling effect. Specifically, the liquid discharged from the liquid outlet can flow into the steam boiler for utilization, reducing resource waste while the high-temperature water flowing into the steam boiler can be quickly heated into steam for output.

[0009] In one embodiment, the steam boiler includes a main boiler and a sub-boiler. The main boiler outputs steam, and the sub-boiler is located within the main boiler. One end of the hot water inlet pipe is connected to a water source, and the other end of the hot water inlet pipe is connected to the storage chamber via the sub-boiler. With this structure, during high-temperature / medium-high-temperature extraction, when the temperature in the storage chamber reaches a preset value, the second pump assembly starts, first pumping high-pressure cold water from the water source, then into the steam boiler sub-boiler. The sub-boiler stores hot water heated by the steam boiler, which, driven by water flow, enters the hot water storage chamber of the hot water boiler through a pipe, maintaining the hot water in the hot water boiler at a high / medium-high temperature.

[0010] In one embodiment, a third water inlet pipe is also included, one end of which is connected to a water source and the other end of which is connected to the steam boiler. A third pump assembly is provided on the third water inlet pipe for supplying water to the steam boiler.

[0011] In one embodiment, the inlet end of the water outlet pipe is connected to the liquid storage chamber via the outlet port, the first outlet end of the water outlet pipe is connected to the steam boiler and / or the water receiving tray, and the second outlet end of the water outlet pipe is used to output the temperature-controlled liquid. A switching valve assembly is provided on the water outlet pipe to control the on / off state of the first and second outlet ends. By adopting the above structure, the output of liquid in the liquid storage chamber can be controlled using only a section of water outlet pipe and the switching valve assembly, which helps to simplify the water circuit structure of the beverage preparation device.

[0012] In one embodiment, the outlet pipeline includes a main pipeline and a first branch and a second branch connected to the main pipeline. One end of the main pipeline is connected to the liquid outlet, and the other end is connected to both the first branch and the second branch. The first branch is connected to the steam boiler and / or the water receiving pan, and the second branch is used to output temperature-controlled liquid. The switching valve assembly includes a first switching valve and a second switching valve. The first switching valve is used to control the on / off state of the first branch, and the second switching valve is used to control the on / off state of the second branch. By adopting the above structure, the liquid discharged from the storage chamber can selectively flow to the steam boiler and / or the water receiving pan, or be output externally, through the two branches on the parallel main pipeline, reducing the number of pipelines and simplifying the structure. Specifically, when the beverage preparation device switches from high-temperature extraction to low-temperature extraction, the second switch valve blocks the second branch, and the first switch valve opens the first branch. At this time, some of the high-temperature water in the storage chamber can flow to the steam boiler and / or water receiving pan in sequence through the outlet, the main pipe and the first branch. When it is necessary to output the temperature-adjusted liquid, the first switch valve blocks the first branch, and the second switch valve opens the second branch. The temperature-adjusted liquid can be output outward in sequence through the outlet, the main pipe and the second branch.

[0013] In one embodiment, the second switching valve is a three-way solenoid valve. The input port of the three-way solenoid valve is connected to the main pipeline, one output port of the three-way solenoid valve is connected to the second branch to output the temperature-controlled liquid, and the other output port of the three-way solenoid valve is connected to the atmosphere. By adopting the above structure, the three-way solenoid valve can be used for on / off control of the second branch and for depressurization of the water outlet pipeline. Specifically, when the three-way solenoid valve is energized, the main pipeline and the second branch are connected, and the temperature-controlled liquid can be smoothly output for extraction. After the extraction is completed, the three-way solenoid valve is de-energized, and the liquid storage chamber is connected to the atmosphere through the liquid outlet, the main pipeline, and the three-way solenoid valve, so that the high-pressure water in the water outlet pipeline is discharged, making it easy to pull out the brewing head assembly.

[0014] In one embodiment, a throttling valve is also included, which is disposed on the main pipeline and is used to control the liquid flow rate entering the first branch or the second branch. By setting the throttling valve, the outlet water flow rate can be controlled, and the user can adjust the water flow rate according to their own extraction habits.

[0015] In one embodiment, a second heating component is provided on the second branch, which is used to heat the liquid flowing through the second branch. By providing the second heating component, the temperature of the liquid not being output from the second branch when the beverage preparation device is in standby mode can be prevented from decreasing, and heating can help reduce the temperature difference between the liquid in the second branch and the liquid in the storage chamber.

[0016] In one embodiment, the second heating component is disposed on the outer wall of the second branch along the extension direction of the second branch.

[0017] In one embodiment, the hot water boiler has a first mounting hole and a second mounting hole on each side, respectively, communicating with the liquid storage chamber. The end of the second branch away from the main pipeline extends into the liquid storage chamber through the first mounting hole and extends to the outside through the second mounting hole. By adopting the above structure, the second branch partially extends into the liquid storage chamber but is not in communication with it. The liquid in the liquid storage chamber can exchange heat with this part of the second branch, thereby preventing the temperature of the liquid not output from the second branch from dropping when the beverage preparation device is on standby, and facilitating the reduction of the temperature difference between the liquid in the second branch and the liquid in the liquid storage chamber.

[0018] In one embodiment, the first heating component is located in the liquid storage chamber, and the first heating component is a heating tube that is spirally wound around the outside of the second branch. By adopting the above structure, during high-temperature extraction, the first heating component heats the liquid in the liquid storage chamber while simultaneously heating the inner second branch. This avoids the temperature drop of the liquid not output from the second branch when the beverage preparation device is in standby mode, and facilitates reducing the temperature difference between the liquid in the second branch and the liquid in the liquid storage chamber.

[0019] In one embodiment, a sealing ring assembly is further included, which is sleeved on the outer wall of the second branch. The sealing ring is used to seal the connection between the second branch and the inner wall of the first mounting hole and / or the second mounting hole. The sealing ring assembly prevents liquid in the storage chamber from leaking through the gap between the second branch and the first mounting hole and / or the second mounting hole.

[0020] In one embodiment, the first mounting hole and the second mounting hole are located on the top wall and bottom wall of the hot water boiler, respectively, and the first mounting hole and the second mounting hole are arranged opposite to each other.

[0021] In one embodiment, a temperature detection component is further included. This temperature detection component is communicatively connected to the control device and is used to detect the temperature within the liquid storage chamber. By including the temperature detection component, the temperature regulation within the liquid storage chamber can be monitored in real time. This allows the control device to conveniently coordinate and control the first heating component, the first pump component, the second pump component, and each switching valve based on the temperature signal fed back by the temperature detection component, thereby achieving automated operation.

[0022] In one embodiment, the water supply module further includes a third switching valve, which is installed on the cold water inlet pipe. The third switching valve is used to control the on / off state of the cold water inlet pipe, and furthermore, the third switching valve is communicatively connected to the control device.

[0023] In one embodiment, the water supply module further includes a fourth switching valve, which is installed on the hot water inlet pipe. The fourth switching valve is used to control the on / off state of the hot water inlet pipe, and furthermore, the fourth switching valve is communicatively connected to the control device.

[0024] In one embodiment, the device further includes a brewing head assembly, wherein the liquid outlet end of the water outlet pipe is configured to deliver temperature-adjusted liquid to the brewing head assembly. Attached Figure Description

[0038] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0040] The beverage preparation apparatus of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 2 As shown, this embodiment discloses a beverage preparation device, including: a hot water boiler 1, which has a liquid storage chamber 101 and a liquid outlet 102 communicating with the liquid storage chamber 101, the liquid outlet 102 being used to discharge the liquid in the liquid storage chamber 101; a first heating component 2, which is disposed on the hot water boiler 1 and is used to heat the liquid in the liquid storage chamber 101; and a water supply module 3, which includes a cold water inlet pipe 31 and a hot water inlet pipe 32, the cold water inlet pipe 31 being connected to the liquid storage chamber. The system is connected to the storage chamber 101. A first pump assembly is installed on the cold water inlet pipe 31 to pump cold water into the storage chamber 101. A second pump assembly is installed on the hot water inlet pipe 32 to pump hot water into the storage chamber 101. A control device is used to control the operation of the first heating component 2, the first pump assembly, and the second pump assembly to adjust the liquid temperature in the storage chamber 101. An outlet pipe 4 is connected to the storage chamber 101 at its input end to output the temperature-adjusted liquid.

[0042] This application provides a beverage preparation apparatus, including a hot water boiler 1, a first heating component 2, a cold water inlet pipe 31, a hot water inlet pipe 32, an outlet pipe 4, and a control device. The control device controls the operation of the first heating component 2, the first pump component on the cold water inlet pipe 31, and the second pump component on the hot water inlet pipe 32. On the one hand, it can drive the first pump component to deliver cold water to the liquid storage chamber 101, so that the exchange and mixing of hot and cold water can take place in the liquid storage chamber 101, thereby quickly achieving temperature regulation of the liquid in the hot water boiler 1. On the other hand, the operation of the first pump component and / or the second pump component can provide power for the output of the temperature-regulated liquid in the liquid storage chamber 101, thereby simplifying the water circuit structure of the beverage preparation apparatus. Specifically, when the beverage preparation device needs to perform high-temperature extraction, the first heating component 2 operates to raise the temperature of the liquid in the storage chamber 101. When the liquid temperature reaches the set temperature value T1, the second pump component is driven to deliver hot water into the storage chamber 101. This allows the temperature-adjusted liquid to be output through the water outlet pipe 4 while the liquid in the storage chamber 101 remains at a high temperature, avoiding affecting the extraction effect. When the beverage preparation device needs to switch to low-temperature extraction, the first heating component 2 stops working. The first pump component is driven to deliver cold water into the storage chamber 101 to mix with the hot water inside, and the high-temperature water in the storage chamber 101 is discharged through the liquid outlet 102. This speeds up the adjustment of the mixing ratio of cold and hot water, improving the cooling effect. When the liquid temperature reaches the set temperature value T2, the first pump component is driven to deliver cold water into the storage chamber 101 to drive the temperature-adjusted liquid to be output and keep the liquid in the storage chamber 101 at a low temperature. Furthermore, when the extraction temperature of the beverage preparation device needs to be adjusted from T2 to T3 (T3 < T1), the first heating component 2 can be driven to heat the liquid in the storage chamber 101 to reach the set temperature value T3. At the same time, the first pump component and the second pump component are driven to work, so that when the temperature-adjusted liquid is output, cold water and hot water can be simultaneously input into the storage chamber 101, which is conducive to maintaining the liquid temperature in a medium-high temperature state.

[0043] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the hot water boiler 1 is provided with a first liquid inlet 103 that communicates with the liquid storage chamber 101, one end of the cold water inlet pipe 31 is connected to the water source, and the other end of the cold water inlet pipe 31 is connected to the liquid storage chamber 101 through the first liquid inlet 103.

[0044] like Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the hot water boiler 1 is provided with a second liquid inlet 104 that communicates with the liquid storage chamber 101, one end of the hot water inlet pipe 32 is connected to the water source, and the other end of the hot water inlet pipe 32 is connected to the liquid storage chamber 101 through the second liquid inlet 104.

[0045] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further includes a steam boiler 5 and / or a water receiving tray, with the liquid outlet 102 connected to the steam boiler 5 and / or the water receiving tray. By adopting the above structure, when the beverage preparation device switches from high-temperature extraction to low-temperature extraction, the liquid in the storage chamber 101 can be discharged into the steam boiler 5 through the liquid outlet 102. This rapidly reduces the high-temperature water content in the storage chamber 101, accelerates the adjustment of the mixing ratio of cold and hot water, and improves the cooling effect. Specifically, the liquid discharged from the liquid outlet 102 can flow into the steam boiler 5 for utilization, reducing resource waste while the high-temperature water flowing into the steam boiler 5 can be quickly heated into steam for output.

[0046] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further defines: the steam boiler 5 includes a main boiler 51 and a sub-boiler 52. The main boiler 51 is used to output steam, and the sub-boiler 52 is disposed in the main boiler 51. One end of the hot water inlet pipe 32 is connected to a water source, and the other end of the hot water inlet pipe 32 is connected to the liquid storage chamber 101 through the sub-boiler 52. By adopting the above structure, during high-temperature / medium-high-temperature extraction, when the temperature in the liquid storage chamber 101 reaches a preset value, the second pump assembly starts to pump high-pressure cold water from the water source first, and then into the sub-boiler 52 of the steam boiler 5. The sub-boiler 52 stores hot water that has been heated by the steam boiler 5. Driven by the water flow, it enters the liquid storage chamber 101 of the hot water boiler 1 through the pipe, so that the hot water in the hot water boiler 1 is kept at a high-temperature / medium-high-temperature state.

[0047] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further includes a third water inlet pipe 35, one end of which is connected to a water source, and the other end of which is connected to a steam boiler 5. A third pump assembly is provided on the third water inlet pipe 35, and the third pump assembly is used to supply water to the steam boiler 5.

[0048] like Figure 1As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inlet end of the water outlet pipe 4 is connected to the storage chamber 101 through the outlet port 102; the first outlet end of the water outlet pipe 4 is connected to the steam boiler 5 and / or the water receiving pan; the second outlet end of the water outlet pipe 4 is used to output the temperature-adjusted liquid; and a switch valve assembly 6 is provided on the water outlet pipe 4 to control the on / off state of the first and second outlet ends. By adopting the above structure, the output of liquid in the storage chamber 101 can be controlled using only a section of water outlet pipe 4 and the switch valve assembly 6, which helps to simplify the water circuit structure of the beverage preparation device.

[0049] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water outlet pipe 4 includes a main pipe 41 and a first branch and a second branch 42 connected to the main pipe 41. One end of the main pipe 41 is connected to the liquid outlet 102, and the other end is connected to the first branch and the second branch 42 respectively. The first branch is connected to the steam boiler 5 and / or the water receiving pan, and the second branch 42 is used to output the temperature-controlled liquid. The switching valve assembly 6 includes a first switching valve 61 and a second switching valve 62. The first switching valve 61 is used to control the on / off state of the first branch, and the second switching valve 62 is used to control the on / off state of the second branch 42. By adopting the above structure, the liquid discharged from the liquid storage chamber 101 can selectively flow to the steam boiler 5 and / or the water receiving pan, or be output externally, through the two branches on the parallel main pipe 41, thereby reducing the number of pipes and simplifying the structure. Specifically, when the beverage preparation device switches from high-temperature extraction to low-temperature extraction, the second switch valve 62 blocks the second branch 42, and the first switch valve 61 opens the first branch. At this time, some of the high-temperature water in the storage chamber 101 can flow sequentially through the outlet 102, the main pipe 41, and the first branch to the steam boiler 5 and / or the water receiving pan. When it is necessary to output the temperature-adjusted liquid, the first switch valve 61 blocks the first branch, and the second switch valve 62 opens the second branch 42. The temperature-adjusted liquid can be output sequentially through the outlet 102, the main pipe 41, and the second branch 42.

[0050] In addition to the features of the above embodiments, this embodiment further specifies that: the second switching valve 62 is a three-way solenoid valve, the input port of the three-way solenoid valve is connected to the main pipeline 41, one output port of the three-way solenoid valve is connected to the second branch 42 to output the temperature-adjusted liquid, and the other output port of the three-way solenoid valve is connected to the atmosphere. By adopting the above structure, the three-way solenoid valve can be used for on / off control of the second branch 42 and for depressurization operation of the water outlet pipeline 4. Specifically, when the three-way solenoid valve is energized, the main pipeline 41 and the second branch 42 are connected, and the temperature-adjusted liquid can be smoothly output for extraction operation; when the extraction is completed, the three-way solenoid valve is de-energized, and the liquid storage chamber 101 is connected to the atmosphere through the liquid outlet 102, the main pipeline 41 and the three-way solenoid valve, so that the high-pressure water in the water outlet pipeline 4 is discharged, making it convenient for the brewing head assembly to be pulled out smoothly.

[0051] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further includes a throttle valve 7, which is disposed on the main pipeline 41 and is used to control the liquid flow rate entering the first branch or the second branch 42. By setting the throttle valve 7, the water flow rate can be controlled, and the user can adjust the water flow rate according to their extraction habits.

[0052] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a second heating component 8 is provided on the second branch 42, and the second heating component 8 is used to heat the liquid flowing through the second branch 42. By setting the second heating component 8, the temperature of the liquid not output from the second branch 42 when the beverage preparation device is in standby mode can be prevented from decreasing, and heating can facilitate the reduction of the temperature difference between the liquid in the second branch 42 and the liquid in the storage chamber 101.

[0053] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second heating component 8 is disposed on the outer wall of the second branch 42 along the extension direction of the second branch 42.

[0054] like Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the hot water boiler 1 has a first mounting hole and a second mounting hole on both sides, which are connected to the liquid storage chamber 101. The end of the second branch 42 away from the main pipeline 41 extends into the liquid storage chamber 101 through the first mounting hole and extends to the outside through the second mounting hole. By adopting the above structure, the second branch 42 extends into the liquid storage chamber 101 but is not connected to the liquid storage chamber 101. The liquid in the liquid storage chamber 101 can exchange heat with this part of the second branch 42, thereby avoiding the temperature drop of the liquid not output from the second branch 42 when the beverage preparation device is on standby, and facilitating the reduction of the temperature difference between the liquid in the second branch 42 and the liquid in the liquid storage chamber 101.

[0055] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first heating component 2 is located in the liquid storage chamber 101, and the first heating component 2 is a heating tube, which is spirally wound around the outside of the second branch 42. By adopting the above structure, during high-temperature extraction, while the first heating component 2 heats the liquid in the liquid storage chamber 101, it can also heat the inner second branch 42. This avoids the temperature of the liquid not output from the second branch 42 when the beverage preparation device is in standby mode from dropping, and facilitates reducing the temperature difference between the liquid in the second branch 42 and the liquid in the liquid storage chamber 101.

[0056] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further includes a sealing ring assembly 9, which is sleeved on the outer wall of the second branch 42. The sealing ring is used to seal the connection between the second branch 42 and the inner wall of the first mounting hole and / or the second mounting hole. By providing the sealing ring assembly 9, leakage of liquid in the liquid storage chamber 101 through the gap between the second branch 42 and the first mounting hole and / or the second mounting hole can be prevented.

[0057] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first mounting hole and the second mounting hole are located on the top wall and bottom wall of the hot water boiler 1, respectively, and the first mounting hole and the second mounting hole are arranged opposite to each other.

[0058] like Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further includes a temperature detection component 10, which is communicatively connected to the control device and is used to detect the temperature inside the liquid storage chamber 101. By setting up the temperature detection component 10, the temperature regulation within the liquid storage chamber 101 can be monitored in real time. This allows the control device to conveniently control and coordinate the first heating component 2, the first pump component, the second pump component, and each switching valve based on the temperature signal fed back by the temperature detection component 10, thereby achieving automated operation.

[0059] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water supply module 3 also includes a third switching valve 33, and the cold water inlet pipe 31 is provided with the third switching valve 33. The third switching valve 33 is used to control the opening and closing of the cold water inlet pipe 31, and further, the third switching valve 33 is communicatively connected to the control device.

[0060] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water supply module 3 also includes a fourth switching valve 34, which is provided on the hot water inlet pipe 32. The fourth switching valve 34 is used to control the on / off state of the hot water inlet pipe 32, and further, the fourth switching valve 34 is communicatively connected to the control device.

[0061] In addition to the features of the above embodiments, this embodiment further specifies that it also includes a brewing head assembly, and the liquid outlet end of the water outlet pipe 4 is configured to deliver temperature-adjusted liquid to the brewing head assembly.

[0062] The technical features of the above embodiments can be combined in any way.
