The gas pipeline 700 is connected to the gas pipeline in the house through the air inlet interface and is connected to the burner to provide gas for the burner. A water flow sensor 201 for collecting the water flow in the water inlet pipeline 200 and a water pump 202 for controlling the water inlet are installed on the water inlet pipeline 200. A water pressure sensor 901 is set on the water outlet pipeline 900. In addition, the water flow sensor 201 and the water pressure sensor 901 are connected to the main controller 300.

[0027] For the above water inlet connector assembly, see Figure 2 , mainly includes three parts, a water inlet joint body 10, an adjustment seat assembly 20 and an adjustment assembly 30, wherein the water inlet joint body 10 is installed at the water inlet end of the water inlet pipe 200 of the gas water heater and communicates with the water inlet pipe 200. The water inlet joint body 10 is T-shaped, having a water channel 11 that runs horizontally through and an adjustment seat assembly installation channel 12 that is perpendicular to the water channel 11, and the two channels are connected. The adjustment seat assembly 20 is installed on the water inlet joint body 10 and inserted from the adjustment seat assembly installation channel 12.

[0028] In a specific embodiment, the adjustment seat assembly 20 includes two parts, a connecting part 21 and a pressure relief part 22, wherein the connecting part 21 is fully inserted into the adjustment seat assembly installation channel 12 of the water inlet joint body 10, and a main channel is arranged in the connecting part 21. After insertion, the main channel is located in the water channel 11, and is connected with the water channels on both sides of the main channel to form a new circulation channel, which is the channel for water inlet pipe 200. A pressure relief channel 221 is arranged in the pressure relief part 22, and the pressure relief channel 221 is connected with the main channel; an adjustment channel 222 is arranged at the rear end of the pressure relief channel 221 in the pressure relief part 22, and a blocking component for blocking the outlet of the pressure relief channel 221 is arranged in the adjustment channel 222. The blocking component implements the opening and closing of the pressure relief channel 221 under the action of the adjustment assembly 30.

[0029] In a specific embodiment, a filter screen 50 is disposed in the main channel of the connecting portion 21 .

[0030] In a specific embodiment, an annular groove is opened on the outer surface of the pressure relief portion 22 , and a sealing ring 60 is arranged in the annular groove to prevent water from flowing out from between the adjustment seat assembly 20 and the installation channel of the adjustment seat assembly 20 .

[0031] See also Figure 2 and Figure 3 The blocking component includes a blocking rod 41, a blocking plug 42 arranged at the front end of the blocking rod 41, and an elastic member 43 sleeved on the blocking rod 41. The blocking plug 42 is adapted to the outlet of the pressure relief channel 221. Under the action of external force, it can resist the outlet of the pressure relief channel 221, thereby preventing water from leaking out. The elastic member in this embodiment is a spring.

[0032] In a specific implementation, the blocking rod 41 includes a guide portion 411 and a blocking plug mounting portion 412 , the elastic member 43 is sleeved on the guide portion 411 , and the blocking plug 42 is mounted on the blocking plug mounting portion 412 .

Driven by the driving component 32, the screw moves upward or downward. When the screw moves downward, it pushes the elastic member 43 to be compressed, driving the blocking rod 41 to move downward, and the sealing plug 42 presses against the outlet of the pressure relief channel 221 to implement sealing. When the screw moves upward, the elastic member 43 is released, and then the sealing effect of the sealing plug 42 on the pressure relief outlet is released. At this time, water can enter the pressure relief channel 221 from the main channel of the connecting portion 21 to implement water discharge and pressure relief.

[0037] The driving component stepper motor is electrically connected to the main controller 300, which controls the gas water heater according to the pressure monitored by the pressure sensor and determines the operation status of the stepper motor according to the relationship between the pressure value and the set value.

[0038] In a specific embodiment, the stepper motor drives the screw to rotate through a gear set. The gear set includes a driving gear arranged at the output end of the stepper motor and a driven gear fixed to the screw. The stepper motor drives the driving gear to rotate, thereby driving the driven gear to drive the screw to rotate.
