[0026] In practical application, the temperature sensing probe of the temperature sensing rod 1 is located close to the water inlet valve 6 to sense the water temperature near the water inlet valve 6. When the water inlet valve 6 is filled with water, the water near the water inlet valve 6 is cooled down through heat exchange, so that the heating element 5 can be started in time.

[0027] Further, the water level probes of the water level probe one 2 and the water level probe two 3 are located at the upper part of the water storage cavity 40, and the position of the water level probe of the water level probe one 2 is higher than that of the water outlet one 42, and the position of the water level probe of the water level probe two 3 is horizontally arranged with the position of the water outlet one 42. In this way, when the water level in the water storage cavity 40 drops to the position of the water level probe of the water level probe two 3, the water level is lower than the position of the water outlet one 42, and hot water cannot be discharged, so as to control the water inlet valve 6 to open and start to fill water. When the water level reaches the position of the water level probe of the water level probe one 2, the filling of water is stopped, and the cycle is repeated to ensure that the water in the water storage bucket 4 remains stable.

The valve core 65 and the valve body 64 are provided with a return spring 66 and a sealing ring 67. In this way, when water is filled, the valve core 65 is opened and the return spring 66 is compressed.

[0030] Further, the valve body 64 is formed with a threaded column 60. The threaded column 60 passes out of the water inlet one 41 and is locked on the bottom of the water storage bucket 4 through the cooperation of a gasket 68 and a nut 69. In this way, the water inlet valve 6 is convenient to assemble and disassemble.

[0031] Further, the water outlet one 42 is connected with the water outlet pump 8 through a water pipe, and the water outlet pump 8 is connected with the spray head 9 through a water pipe. In this way, water is sprayed and brewed under the pressure of the water outlet pump 8.

[0032] Further, the water storage bucket 4 top is provided with a pressure relief pipe 43.

[0033] Further, the heating element 5 comprises an M-type heating tube, the M-type heating tube is arranged around the outer periphery of the water inlet valve 6, and the two ends of the M-type heating tube pass through the bottom of the water storage bucket 4 and are locked on the bottom of the water storage bucket 4 by locking members. In this way, the heating element 5 can heat the water injected through the water inlet valve 6 in time.

[0034] Further, the water inlet valve 6, the heating element 5, the temperature sensing rod 1, the water level probe one 2 and the water level probe two 3 are respectively and sealingly arranged in the water storage bucket 4. In this way, the water vapor in the water storage bucket 4 is prevented from leaking out.

[0035] Further, a controller is further included, and the controller is electrically connected to the water inlet valve 6, the heating element 5, the temperature sensing rod 1, the water level probe one 2 and the water level probe two 3. In this way, when water is injected, the controller controls the water inlet valve 6 to open, when the water level reaches the water level probe one 2, the controller is fed back, the controller controls the water inlet valve 6 to close, and the controller controls the heating element 5 to heat, when the water temperature reaches the set temperature, the temperature sensing rod 1 feeds back to the controller, the controller controls the heating element 5 to stop heating, and when the water level reaches the water level probe two 3, the controller is fed back, and the controller controls the water inlet valve 6 to open.

[0036] As shown in Figure 3 The working principle of the water storage type heating boiler for brewing coffee is shown in the working schematic diagram.

[0037] In the initial state, the water storage bucket 4 is empty, cold water is injected into the water storage bucket 4 through the water inlet valve 6 by the pressurization of the water inlet pump 7, when the water level reaches the water level probe position of the water level probe one 2, the water inlet pump 7 stops working, the water inlet valve 6 closes, and the water is heated by the heating element 5, when the temperature sensing rod 1 senses that the water temperature reaches the set temperature, the heating stops, the brewing switch is pressed, the water outlet pump 8 works, hot water is sprayed onto the coffee powder in the coffee filter basket 10 through the water outlet pump 8 and the spray head 9, and the coffee liquid finally flows into the coffee cup 11; when the brewing water level reaches the water level probe position of the water level probe two 3, the hot water cannot be discharged, the water inlet pump 7 is started again, the water inlet valve 6 is opened, and cold water is injected into the water storage bucket 4 through the water inlet valve 6, the cold water slowly rises around the bottom area of the water storage cavity 40, the temperature sensing rod 1 detects that the water temperature at the bottom of the water storage cavity 40 is too low, the heating element 5 is started again to heat the cold water at the bottom of the water storage cavity 40 to the specified temperature, so that the water temperature in the middle of the water storage cavity 40 and the upper part of the water outlet one 42 is kept constant, when the water level reaches the water level probe position of the water level probe one 2, the water inlet pump 7 stops working, the water inlet valve 6 closes, and the cycle works.
