[0006] The present application discloses a coffee machine. By arranging a water pump assembly, a heating assembly, a brewing assembly and a steam assembly in a receiving cavity provided in a housing assembly, firstly, the internal space of the housing assembly is fully utilized, reducing the overall volume of the coffee machine. Secondly, multiple key components are concentrated in one receiving cavity, achieving a high degree of integration of the coffee machine, reducing the connections and wiring between components, making the structure more compact. From the appearance, the appearance of the coffee machine is more concise and beautiful, without too many exposed parts. At the same time, the receiving cavity provides a certain protection for each component, reducing the damage to the components caused by external factors such as dust, collision, moisture, etc., and extending the service life of each component. The water tank assembly is arranged in a water tank accommodating hole provided in the housing assembly, providing a clear installation position for the water tank assembly, enabling it to be stably placed in the coffee machine, avoiding displacement or shaking during use, integrating the water tank assembly with the housing assembly, making the appearance more neat and smooth, further improving the overall aesthetics of the coffee machine.

By arranging the water tank accommodating hole and the water supply port on the bottom housing assembly, the bottom housing assembly can provide more stable support for the water tank assembly, ensuring that the water tank assembly will not shake or displace during installation and use, thereby ensuring the stability of water supply. At the same time, by utilizing the gravity difference that the position of the water tank assembly is higher than the water supply port, water can naturally flow to the water supply port, reducing the dependence on additional power equipment and simplifying the water supply system.

[0008] In one embodiment, the upper shell assembly includes a main housing, a hanging member, and an upper cover. The main housing is disposed on the bottom shell assembly, the hanging member and the upper cover are disposed on the main housing, and the hanging member is adaptively installed with the water tank assembly. By disposing the main housing on the bottom shell assembly, the bottom shell assembly can provide a more stable basic support, and after being combined with the main housing, it can enhance the structural strength of the entire coffee machine, making it not easily deformed or damaged during use. Disposing the hanging member and the upper cover on the main housing, the upper cover further plays a protective role, preventing dust and foreign objects from entering, protecting the cleanliness and safety of the internal components, while the hanging member provides a supporting role for the water tank assembly, ensuring the stable position of the water tank assembly in the coffee machine, reducing problems such as water leakage or loose connection that may be caused by shaking or displacement, and at the same time sharing the weight of the water tank borne by the bottom shell assembly, reducing the risk of deformation or damage of the bottom shell assembly due to long-term bearing of the water tank pressure.

[0009] In one embodiment, the bottom shell assembly includes a base, a water inlet device, a flow meter, and a support frame. The main housing is disposed on the base, the base is provided with the water tank accommodating hole, the water inlet device is disposed on the base and at the water tank accommodating hole, the flow meter is disposed on the base and in the accommodating cavity, the water inlet device is communicated with the flow meter water inlet through a pipeline, and the support frame is disposed on the base. By disposing the main housing on the base, it can prevent the main housing from directly contacting the ground or the tabletop, avoiding damage caused by moisture, dirt, or collision, thereby better protecting the internal functional components. Disposing the water inlet device on the base and at the water tank accommodating hole provided on the base, making full use of the space of the base, making the overall structure of the coffee machine more compact, saving internal space, and being able to cooperate closely with the water tank assembly to achieve the purpose of making the coffee machine more convenient to obtain water. Disposing the flow meter on the base assembly and in the accommodating cavity, and the water inlet device is communicated with the flow meter water inlet through a pipeline, ensuring that the water flow can be measured by the flow meter and then enter the subsequent processing link, making the measurement data accurate and reliable, thereby ensuring the consistency of the water consumption for each coffee brewing and ensuring the stability of the coffee taste and quality.

[0010] In one embodiment, the water tank assembly includes a water tank and a hook. The hook is provided on the water tank, and the hook is hung on the hanging member. The water tank is arranged on the base. The water tank is provided with the water storage cavity and the water discharge channel. The water inlet device is provided with the water supply port. The water tank can be separated from or abutted against the water inlet device. When the water tank abuts against the water inlet device, the water discharge channel is communicated with the water supply port. When the water tank is separated from the water inlet device, the water discharge channel is blocked from the water supply port. By arranging the hook on the water tank and hanging the water tank on the hanging member provided on the housing assembly using the hook, this design enables the user to easily hang or remove the water tank assembly, facilitating operations such as water filling, cleaning, or maintenance, and ensuring that the water tank assembly has a definite and stable position within the coffee machine, preventing the water tank from moving or shaking during use and affecting the stability of water supply. The water tank is arranged on the base and at the water tank accommodation hole, and the water inlet device can abut against or be separated from the water tank. When the user lifts the water tank assembly to add water, the water discharge channel is blocked from the water supply port. When the user places the water tank assembly on the base, the water inlet device abuts against the water tank assembly. At this time, the water storage cavity, the water discharge channel, and the water supply port are sequentially communicated. This structure realizes the automatic connection of the water tank assembly to the coffee machine water supply system without additional operations, which is convenient and fast, ensuring that after the water tank is placed in place, water can continuously and stably flow from the water tank assembly into the coffee machine to meet the water usage requirements during the coffee-making process.

[0011] In one embodiment, the water pump assembly includes a water pump and a safety valve. The safety valve is disposed on the water pump, and the water pump is disposed on the housing assembly. The water pump is provided with a pump water inlet, and the pump water inlet is communicated with the flowmeter water outlet provided on the flowmeter or the pump water inlet is communicated with the water supply port. The safety valve is provided with a pressure relief port, and the water inlet device is provided with a return port, and the pressure relief port is communicated with the return port. By disposing the water pump on the housing assembly, and the pump water inlet of the water pump is communicated with the flowmeter water outlet provided on the flowmeter or with the water supply port, when it is necessary to use the flowmeter to detect the water supply flow rate, the pump water inlet can be communicated with the flowmeter water outlet of the flowmeter, and according to the measurement data of the flowmeter, the water flow rate entering the water pump can be accurately controlled, so as to ensure the accuracy of the water volume for coffee brewing and guarantee the stability of coffee quality. When the flowmeter is not needed, the pump water inlet is directly communicated with the water supply port, making the water path more concise and direct, reducing the water flow resistance and energy loss, improving the water supply speed and efficiency, and at the same time reducing the complexity of the water path system and potential failure points. By disposing the safety valve on the water pump, and the pressure relief port provided on the safety valve is communicated with the return port provided on the water inlet device, first, when the pressure generated by the water pump exceeds the safety threshold, the safety valve will automatically open for pressure relief. At this time, the water flow returns from the water pump to the water tank assembly, effectively preventing damage to the water pump, pipeline and other components caused by excessive pressure, and extending the service life of the equipment. Second, it helps to maintain the pressure stability in the water path system of the coffee machine, ensuring that the water pressure during coffee making is within a suitable range, thereby guaranteeing the extraction quality and taste consistency of coffee and enhancing the user experience.

[0012] In one embodiment, the heating assembly is provided with a heating water inlet and a heating water outlet, the heating water inlet is communicated with the heating water outlet, the water pump assembly is provided with a pump water outlet, the pump water inlet is communicated with the pump water outlet, and the pump water outlet is communicated with the heating water inlet. By communicating the heating water inlet provided on the heating assembly with the pump water outlet, at this time, the water pump assembly pumps the water flow from the water supply port into the pump body, flows in from the pump water inlet, then flows out from the pump water outlet and enters the heating assembly from the heating water inlet, and the heating assembly heats it, which can quickly provide hot water at the required temperature for coffee brewing and improve the efficiency of making coffee. This direct communication enables the heating assembly to more precisely control the heating process of the incoming water, making the water path system more compact and direct, reducing unnecessary pipelines and connectors, lowering the complexity of the system and potential failure points, and at the same time helping to achieve stable and accurate water temperature control to guarantee the quality and taste of coffee.

[0013] In one embodiment, the brewing assembly includes a brewing head and a brewing handle. The brewing head is disposed on the housing assembly and partially located in the accommodation cavity. The brewing handle is disposed on the brewing head. The brewing head is provided with a brewing water inlet and a brewing water outlet, and the heating water outlet, the brewing water inlet, and the brewing water outlet are sequentially connected. By disposing the brewing head on the housing assembly and partially located in the accommodation cavity, the accommodation cavity can provide certain protection for the brewing head, protecting it from external collisions and extending its service life. At the same time, it ensures that the brewing head remains stable during the operation of the coffee machine and will not be displaced or shaken due to vibration or other factors, thus guaranteeing the accuracy and stability of brewing. Disposing the brewing handle on the brewing head forms the brewing assembly, enabling the user to complete the actions of powder loading and brewing at the same position, making the operation process more coherent and convenient, saving time and effort. Since the brewing head is provided with a brewing water inlet and a brewing water outlet, the heated water flow flows out from the heating water outlet and enters the brewing assembly through the brewing water inlet. The user controls the coffee to flow out from the brewing water outlet by operating the brewing handle, and at this time, the user can enjoy the steaming hot coffee, meeting the user's usage requirements.

[0014] In one embodiment, the steam assembly includes a steam valve and a steam pipe. The steam valve is disposed on the housing assembly and located in the accommodation cavity. The steam valve is provided with a first steam port and a second steam port. The brewing assembly is provided with an air outlet, and the air outlet, the first steam port, and the second steam port are sequentially connected. The steam pipe is connected to the steam valve through a pipeline. The steam pipe is disposed on the housing assembly and passes through the accommodation cavity. By disposing the steam valve on the housing assembly and located in the accommodation cavity, the accommodation cavity provides certain physical protection for the steam valve, reducing the risk of it being damaged by external collisions. At the same time, it helps to maintain the temperature around the steam valve, reducing the heat loss of the steam during transmission and improving the energy utilization efficiency. The steam valve is provided with a first steam port and is connected to the air outlet provided on the brewing assembly. When milk needs to be foamed, the heating assembly turns the water source into steam. Since the brewing head is provided with a one-way valve, the steam is ejected from the air outlet of the brewing head and enters the steam valve. At this time, the user opens the steam valve and the steam pipe, and the steam finally comes out from the steam pipe, realizing the process of milk foaming, enriching the coffee making methods and taste, and meeting the actual needs of the user. Disposing the steam pipe on the housing assembly and exposing it can ensure that the steam can reach the area where it needs to play a role smoothly, and it is also convenient for the user to operate, reducing the difficulty and complexity of the operation.

[0015] In one embodiment, it further includes a circuit board assembly, which is disposed on the housing assembly and located in the accommodation cavity. The circuit board assembly is electrically connected to the water pump assembly and the heating assembly respectively. By arranging the circuit board assembly on the housing assembly and within the accommodation cavity, the accommodation cavity can provide certain physical protection for the circuit board assembly, reducing damage caused by external impacts, dust, water vapor, etc., extending the service life of the circuit board assembly, and at the same time ensuring that the circuit board assembly will not loosen due to vibration or other factors during the operation of the coffee machine, guaranteeing the stability of the circuit connection. The circuit board assembly is used to control the water pump assembly and the heating assembly, realizing precise control and adjustment of the water flow rate and water temperature, making the coffee machine more convenient and intelligent to use.

[0016] In one embodiment, it further includes a display assembly, which is disposed on the housing assembly and partially located in the accommodation cavity. By arranging the display assembly on the housing assembly and partially within the accommodation cavity, the accommodation cavity provides a certain degree of physical protection for the display assembly, reducing the risk of damage caused by collisions, scratches, liquid splashes, etc., and at the same time enabling the display assembly to better integrate with the housing assembly, enhancing the overall aesthetics and coordination of the coffee machine and improving its market competitiveness.

[0047] As Figure 1 , Figure 3 , Figure 5 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines that: the water pump assembly 3 includes a water pump 31 and a safety valve 32. The safety valve 32 is arranged on the water pump 31, and the water pump 31 is arranged on the housing assembly 1. The water pump 31 is provided with a water inlet 301, and the water inlet 301 is communicated with the water outlet 106 of the flow meter 123 or the water inlet 301 is communicated with the water supply port 102. The safety valve 32 is provided with a pressure relief port 303, and the water inlet device 122 is provided with a return port 104. The pressure relief port 303 is communicated with the return port 104. By arranging the water pump 21 on the housing assembly 1 and communicating the water inlet 301 of the water pump 31 with the water outlet 106 of the flow meter 123 or with the water supply port 102, when it is necessary to use the flow meter 123 to detect the water supply flow rate, the water inlet 301 can be communicated with the water outlet 106 of the flow meter 123. According to the measurement data of the flow meter 123, the water flow rate entering the water pump 31 can be accurately controlled, so as to ensure the accuracy of the water volume for coffee brewing and guarantee the stability of coffee quality. When the flow meter 123 is not needed, the water inlet 301 is directly communicated with the water supply port 102, making the water path more concise and direct, reducing the water flow resistance and energy loss, improving the water supply speed and efficiency, and at the same time reducing the complexity of the water path system and potential failure points. The safety valve 32 is arranged on the water pump 31, and the pressure relief port 303 of the safety valve 32 is communicated with the return port 104 of the water inlet device 122. First, when the pressure generated by the water pump 31 exceeds the safety threshold, the safety valve 32 will automatically open for pressure relief. At this time, the water flow returns from the water pump 31 to the water tank assembly 2, effectively preventing excessive pressure from damaging the water pump 31, pipelines and other components, and extending the service life of the equipment. Second, it helps to maintain the pressure stability in the water path system of the coffee machine, ensuring that the water pressure during coffee making is within a suitable range, so as to guarantee the extraction quality and taste consistency of coffee and improve the user experience.

[0048] As Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: the heating component 4 is provided with a heating water inlet 401 and a heating water outlet 402, the heating water inlet 401 is connected to the heating water outlet 402, the water pump component 3 is provided with a pump water outlet 302, the pump water inlet 301 is connected to the pump water outlet 302, and the pump water outlet 302 is connected to the heating water inlet 401. By connecting the heating water inlet 401 provided in the heating component 4 with the pump water outlet 302, the water pump component 3 draws water from the water supply port 102 into the pump body, flows in from the pump water inlet 301, then flows out from the pump water outlet 302 and enters the heating component 4 from the heating water inlet 401. The heating component 4 heats the water and can quickly provide hot water of the required temperature for coffee brewing, thereby improving the efficiency of making coffee. This direct connection enables the heating component to more accurately control the heating process of the incoming water, making the water system more compact and direct, reducing unnecessary pipes and connectors, reducing the complexity of the system and potential failure points, and also helping to achieve stable and accurate water temperature control to ensure the quality and taste of the coffee.

[0049] like Figure 1 , Figure 5 , Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the brewing assembly 5 includes a brewing head 51 and a brewing handle 52, the brewing head 51 is arranged on the housing assembly 1 and partially located in the accommodating chamber 101, the brewing handle 52 is arranged on the brewing head 51, the brewing head 51 is provided with a brewing water inlet 501 and a brewing water outlet 502, and the heating water outlet 402, the brewing water inlet 501 and the brewing water outlet 502 are sequentially connected.

The steam valve 61 is provided with a first steam port 601 and is communicated with the air outlet 503 provided on the brewing assembly 5. When it is necessary to foam the milk, the heating assembly 4 is used to turn the water source into steam. Since the brewing head 51 is provided with a one-way valve, the steam is ejected from the air outlet 503 of the brewing head 51 and enters the steam valve 61. At this time, the user opens the steam valve 61 and the steam pipe 62, and the steam finally comes out from the steam pipe 62, realizing the process of whipping the milk, enriching the coffee making method and taste, and meeting the actual needs of users. Arranging the steam pipe 62 on the housing assembly 1 and exposing it can ensure that the steam can reach the area where it needs to play a role smoothly, and is convenient for users to operate, reducing the difficulty and complexity of the operation.
