[0006] Furthermore, a plurality of the dual anti-dumping switches may be provided in the control box, and each of the dual anti-dumping switches is arranged in a vertical direction in the control box.

[0007] Furthermore, a bearing mechanism is provided on the pressure plate to bear the steel ball.

[0008] Furthermore, the double anti-dump switch is also provided with assembly screws for installation and reinforcement.

[0009] Furthermore, a dump switch replacement window is also provided on the control box.

[0010] Furthermore, the dump switch replacement window is a rectangular structure arranged in the up-down direction.

[0011] Furthermore, the window length of the dump switch replacement window is adapted to the number of the dual anti-dump switches.

[0012] The heater includes a heater body and a control box, wherein a double anti-dump switch is arranged in the control box; the double anti-dump switch includes a double anti-dump switch housing, a steel ball is arranged in the cavity of the double anti-dump switch housing, the steel ball presses down a pressure plate below, and the pressure plate simultaneously presses down a first anti-dump switch and a second anti-dump switch arranged in parallel on the left and right below it; the first anti-dump switch and the second anti-dump switch are connected in parallel between the main burner head assembly and the valve assembly of the heater body, so that when the anti-dump switch fails due to increased resistance or decreased sensitivity caused by terminal oxidation, there will still be a spare anti-dump switch to cut off the gas supply and automatically shut down the continued burning of the flame at the first time, thereby reducing the failure rate of the heater and improving its safety performance, protecting the safety of users.
