Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present invention is not limited in this respect.

[0027] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to". The term "connection" can refer to a direct connection or an indirect connection via intermediate components (elements). The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the following description.

[0028] See Figures 1 to 6 This invention relates to a tea and coffee beverage making machine, which automatically completes the brewing, boiling, and steeping process of beverage ingredients such as tea and coffee to produce the required tea, coffee, fruit tea, or milk tea beverages, ensuring the taste of the beverages.

[0029] The tea and coffee beverage making machine includes a frame, a boiler 300, a beverage making tank 200, a water injection system 400, a water dispensing device, and a control system. The boiler 300, water injection system 400, water dispensing device, and control system are all located within the frame. The beverage making tank 200 is used to hold tea and coffee beverage ingredients and can be hung on the frame 100 via its top hanging lug 212. The water injection system 400 is connected between the boiler 300 and the beverage making tank 200 and is electrically connected to the control system, thereby injecting brewing water from the boiler 300 into the beverage making tank 200 under the control of the control system. The water dispensing device is electrically connected to the control system and can act on the beverage making tank 200 under the control of the control system to discharge the beverage from the beverage making tank 200.

[0030] The water injection system 400 includes at least two water inlets 410, and the beverage making bucket 200 includes a bucket lid 240. The bucket lid 240 is provided with water inlets 241 corresponding to the number of water inlets 410. The water inlets 410 are installed one-to-one above the water inlets 241 and are fixed on the frame in such a way that water is injected into the bucket at an angle.

[0031] Preferably, the water inlet holes 241 are evenly distributed on the lid 240 along the circumferential direction, and the water flow from the water inlet 410 is directed towards the adjacent water inlet 410 at an angle, thereby forming a vortex rotating in a clockwise or counterclockwise direction inside the bucket to achieve a stirring function, thereby improving the brewing effect and ensuring the taste of the beverage.

[0032] Therefore, in this invention, by setting at least two water inlets 410 to inject water into the bucket and setting the water flow direction of the water inlets 410, the stirring function is achieved through the water flow of the water inlets 410, without the need to set an additional stirring device, which facilitates the assembly of the tea and coffee beverage making machine and reduces costs.

[0033] It should be understood that the present invention shows two water inlets 410 and two water inlets 241, but this does not mean that only two water inlets 241 and two water inlets 410 can be provided. As the number of water inlets 410 increases, the stirring effect is better. The number of water inlets 410 and water inlets 241 can be set by technicians according to actual needs.

[0034] Furthermore, the water injection system 400 also includes a spray head 420, which is a 360° rotating spray head. The bucket lid 240 is also provided with a spray hole 242, through which the spray head 420 sprays water into the bucket, thereby moistening the tea and coffee raw materials, such as moistening dry tea leaves to increase their weight, preventing them from floating on the water surface during brewing, and improving the brewing effect.

[0035] In one embodiment, the spray hole 242 is located at the center of the bucket lid 240, and the at least two water inlets 410 are arranged around the spray hole 242. When two water inlets 241 are provided, the two water inlets 241 are located at opposite ends of the diameter of the spray hole 242. By placing the spray hole 242 at the center of the bucket lid 240, the water flow from the spray head 420 can cover all parts of the bucket, ensuring that the raw materials are fully wetted.

[0036] In one embodiment, the water injection system 400 further includes a multi-way solenoid valve 450 electrically connected to the control system. The multi-way solenoid valve 450 has a water inlet and multiple passages switchably connected to the water inlet. The water inlet of the multi-way solenoid valve 450 is connected to the outlet of the boiler 300 via a water inlet pipe 440. The at least two water injection holes 241 are combined and connected to one passage of the multi-way solenoid valve 450. The spray head 420 is connected to the other passage of the multi-way solenoid valve 450. This allows the raw materials to be sprayed and moistened before water is injected for brewing, improving the brewing effect, according to the control system. Furthermore, the use of the multi-way solenoid valve 450 facilitates the assembly of the water injection system 400 and simplifies the piping within the frame.

[0037] The water injection system 400 also includes a heating pipe and an instant heating pipe 430. The heating pipe is located inside the boiler 300, and the instant heating pipe 430 is located between the boiler 300 and the water inlet of the multi-way solenoid valve 450. Both the heating pipe and the instant heating pipe 430 are electrically connected to the control system.

[0038] In one embodiment, one of the passages of the multi-way solenoid valve 450 is also connected to the boiler 300 via a return pipe 470.

[0039] By installing the instant heating pipe 430, the brewing water flowing from the boiler 300 is prevented from cooling down rapidly as it flows to the beverage preparation container 200, ensuring the brewing effect. Additionally, by connecting the return pipe 470 to the boiler 300, the pipes are preheated by flushing them with hot water before filling the container. This prevents a large temperature difference between the pipes and the brewing water from cooling down, thus achieving the pipe preheating function and further guaranteeing the brewing effect.

[0040] In one embodiment, the water injection system 400 further includes a flow meter 460, which is connected between the instant heating pipe 430 and the water inlet of the multi-way solenoid valve 450 and electrically connected to the control system. By setting the flow meter 460 to precisely control the flow rate of the brewing water, the brewing effect of tea and coffee beverages can be further guaranteed.

[0041] Understandably, the boiler 300 is also equipped with a liquid level control device that includes low water level detection and high water level detection. The frame 100 also contains a water inlet pump, which outputs a low water level signal to the control system when the water level is low, causing the control system to control the water inlet pump connected to the boiler 300 to add water to the boiler 300. Water inlet stops when the water level reaches a high level. The heating element, instant heating element 430, and flow meter 460 are all electrically connected to the control system to heat the water for brewing and to control the flow rate under the control of the control system.

[0042] In one embodiment, the water outlet device includes a rocker arm 600 and a push rod 510 motor, the rocker arm 600 being hinged to the frame, the push rod 510 motor being electrically connected to the control system, and its push rod 510 being able to act on one end of the rocker arm 600.

[0043] The beverage preparation container 200 also includes a container body 210, a filter screen 230, and a valve 220. The bottom of the container body 210 has an installation hole communicating with the interior space of the container. The filter screen 230 covers the installation hole, and the valve 220 is installed within the installation hole. The valve 220 includes a valve stem 221, a nut, and a compression spring. One end of the valve stem 221 has a blocking portion 2211. The valve stem has an inlet 2212 and an outlet 2213, with the inlet located on the valve stem. On the periphery, the outlet is located at the end of the valve stem away from the blocking part and communicates with the inlet. The end of the valve stem 221 away from the blocking part 2211 forms an external thread 2214. The nut is connected to the external thread and is used for the lever 600 to apply force to the valve so that the blocking part 2211 is pushed open to expose the inlet 2212. The compression spring is pressed between the bottom of the bucket and the nut, and is used to block the mounting hole of the valve stem when the force on the nut is removed. The inlet is located in the mounting hole at the bottom of the bucket.

[0044] Furthermore, the end of the blocking part 2211 facing the water inlet 2212 is provided with a sealing groove 2215, which is used to fill the sealing material and achieve a sealing function when the blocking part blocks the mounting hole.

[0045] Furthermore, the barrel body surrounds the valve to form a decorative ring 250. The decorative ring 250 is provided with a clearance notch 251 for the rocker arm 600 to extend into. By setting the decorative ring to cover the valve 220, the valve is prevented from being exposed, thus avoiding affecting the aesthetics of the beverage making barrel 200.
