At the same time, when the cup receives water, the elastic force of the spring 18 is used to offset the impact of the falling water. If it is necessary to clean the inside of the device, manually rotate the sealing cover 2, open the device body 1, and remove the stirring sleeve 7 from the slots set at the bottom of the hot water tank 22 and the cold water tank 23 through the circular hole set at the top, so that the solid residue can be statically precipitated in the circular slots at the bottom of the hot water tank 22 and the cold water tank 23, which is convenient for cleaning the inside of the hot water tank 22 and the cold water tank 23, and at the same time, it is convenient to disassemble and assemble the stirring sleeve 7 for washing.

[0037] One innovation implementation step:

[0038] Step 1: Start the water inlet and outlet solenoid valves 20 through the control panel 4 to fill water into the hot water tank 22 and the cold water tank 23, observe the water level on the control panel 4, close the water inlet and outlet solenoid valves 20 when the water is almost filled, energize and heat the electric heating tube 21 through the control panel 4, observe the screen of the control panel 4 and stop heating when the water temperature inside the hot water tank 22 reaches a suitable temperature;

[0039] Step 2: Manually rotate the sealing cover 2 to place the solvent such as tea or coffee inside the stirring sleeve 7, so that the bottom limit block of the sealing cover 2 enters the clamping ring at the top of the stirring sleeve 7, and manually reverse the sealing cover 2 to fix it on the top outer wall of the device body 1;

[0040] Step 3: Start the driving gear 11 through the control panel 4 to fully stir the solvent inside the stirring sleeve 7. When the tea and coffee are fully brewed, place the receiving cup on the load-bearing plate 3, start the water pump 8 through the control panel 4, and let the mixed liquid flow out from the water outlet 13 and fall into the cup. This structure can not only supply hot and cold at the same time, but also can maintain constant temperature and quantity, accelerate the dissolution speed of the solvent inside the stirring sleeve 7, make it fully mixed with water, and effectively prevent the liquid in the receiving cup from splashing.

[0041] The second innovation point implementation steps:

[0042] Step 1: manually rotate the sealing cover 2, open the device body 1, and take out the stirring sleeve 7 from the slots provided at the bottom of the hot water tank 22 and the cold water tank 23 through the circular hole provided at the top;

[0043] Step 2: by standing still, the solid residue inside is precipitated into the circular slot provided at the bottom of the hot water tank 22 or the cold water tank 23;
