When the water quantity in the installation pipe 200 is increased, the piston 4 is compressed, the piston rod 5 presses down one end of the adjusting rod 2, and the end, fixed with the fire detection needle 3, of the adjusting rod 2 is lifted, so that the height of the fire detection needle 3 is increased, and the installation pipe is suitable for higher flame height. When the amount of water in the installation tube 200 decreases, the piston 4 is reset, and the height of the fire detection needle 3 is lowered.
When the fire detection needle adjustment assembly 100 is applied to a gas water heater, the installation pipe 200 is communicated with the water flow pipe 401 of the heat exchanger 400. Examine the upper end setting of fire needle 3 near the flame of fire hole 301 of fire row 300, examine the height that fire needle 3 can detect flame to judge whether the burning is abundant. When the flame is sufficiently burnt, the flame does not touch the fire detection needle 3, and the fire detection needle 3 cannot detect the flame; at this time, the fire detection needle 3 sends a fourth flame signal to the controller 900, and the controller 900 controls the fan 500 to maintain the predetermined rotation speed when receiving the fourth flame signal. When the flame is not fully combusted, the height of the flame can be increased, the fire detection needle 3 sends a third flame signal to the controller 900 when detecting the flame, and the controller 900 controls the fan 500 to increase the rotating speed and supplement secondary air of the flame when receiving the third flame signal, so that the flame can reach a fully combusted state, and the height of the flame is reduced to a normal value.
When the water amount in the water flow pipeline 401 of the heat exchanger 400 is large, the required flame has large firepower, and the normal value of the flame height is high; when the amount of water in the water flow pipe 401 of the heat exchanger 400 is small, the required fire power of the flame is small, and the normal value of the height of the flame is small at this time.

In contrast, the end surface 201 of the mounting pipe 200 communicating with the water flow channel 401 forms a communication hole 202, and the diameter of the communication hole 202 is smaller than that of the mounting pipe 200. The communication hole 202 communicates the mounting tube 200 with the water flow channel 401, and the end surface 201 of the mounting tube 200 can define the limit position of the piston 4.

The height of the fire detection needle 3 can be adjusted according to the water quantity in the water flow pipeline 401 of the heat exchanger 400, so that the height of the fire detection needle 3 is suitable for the required fire power of flame.
The fire detection needle 3 is arranged close to the upper end of the flame of the fire hole of the fire grate 300, and the fire detection needle 3 is used for controlling the fan 500 to increase the rotating speed when detecting the flame.
Specifically, the fire detection needle 3 is arranged close to the upper end of the flame of the fire hole 301 of the fire row 300, and the flame signal of the fire detection needle 3 is a third flame signal and a fourth flame signal; the fire detection needle 3 is used for sending a third flame signal to the controller 900 when detecting a flame, and the controller 900 is used for controlling the fan 500 to increase the rotating speed when receiving the third flame signal; the fire detection needle 3 is further configured to send a fourth flame signal to the controller 900 when no flame is detected, and the controller 900 is further configured to control the fan 500 to maintain a predetermined rotation speed when receiving the fourth flame signal.
The flame height is determined by the air quantity and the heat load (i.e., the gas quantity), and the flame height is correspondingly lower as the air quantity is larger when the heat load is unchanged. By providing the fire detection needle 3 near the upper end of the flame of the fire hole 301 of the fire grate 300, the height of the flame can be detected, thereby determining whether the combustion is sufficient. When the flame is sufficiently burnt, the flame does not touch the fire detection needle 3, and the fire detection needle 3 cannot detect the flame; at this time, the fire detection needle 3 sends a fourth flame signal to the controller 900, and the controller 900 controls the fan 500 to maintain the predetermined rotation speed when receiving the fourth flame signal. When the flame is not fully combusted, the height of the flame can be increased, the fire detection needle 3 sends a third flame signal to the controller 900 when detecting the flame, and the controller 900 controls the fan 500 to increase the rotating speed and supplement secondary air of the flame when receiving the third flame signal, so that the flame can reach a fully combusted state, and the height of the flame is reduced to a normal value.

By placing the lower fire detection needle 800 close to the fire hole 301 of the fire row 300, the lower fire detection needle 800 can detect whether the fire row 300 is successfully ignited. When the fire grate 300 is not ignited successfully, the lower fire detection needle 800 cannot detect flames, at this time, the lower fire detection needle 800 sends a second flame signal to the controller 900, and the controller 900 controls the fire grate 300 to stop burning when receiving the second flame signal, namely, controls the gas proportional valve 600 and the fan 500 to be closed, and displays a prompt that ignition cannot be performed on the display after the gas proportional valve 600 and the fan 500 are closed for 30 seconds. When the fire grate 300 is ignited successfully, the lower fire detection needle 800 can detect flame, at the moment, the lower fire detection needle 800 sends a first flame signal to the controller 900, and the controller 900 controls the fire grate 300 to keep burning normally, namely, controls the gas proportional valve 600 and the fan 500 to operate normally.

Under normal conditions, the flame will not burn to the fins of the heat exchanger 400, but if the heat exchanger is used for a long time to generate carbon deposition, corrosion and the like to block the fin gaps, the combustion air is seriously insufficient, and the height of the flame at this time is increased, so that the flame can burn to the fins. In order to solve this problem, whether the flame burns to the fins of the heat exchanger 400 can be detected by the upper fire detection pins 700 provided near the lower end of the heat exchanger 400. When the upper fire detection needle 700 continuously detects the flame for more than one minute, a fifth flame signal is sent to the controller 900, and the controller 900 controls the fire grate 300 to stop burning when receiving the fifth flame signal, namely controls the gas proportional valve 600 and the fan 500 to be closed, and displays a prompt that the fire cannot be ignited on the display after the gas proportional valve 600 and the fan 500 are closed for 30 seconds.
