[0057] The water outlet valve assembly 1 further comprises a pressure-sensitive alarm 30 abutting against a side of the first sealing member 22 away from the water inlet channel 11 and installed in the containing cavity 211, the pressure-sensitive alarm 30 being configured to send an alarm when an acting force exerted on the pressure-sensitive alarm 30 by the first sealing member 22 under water pressure is greater than a preset acting force.

[0058] In this way, by arranging the pressure-sensitive alarm 30, when the water pressure is too large, the pressure relief can be accompanied by a beeping reminder to the user, so that the user can know that the water heater is in pressure relief at the first time, and the room is prevented from being soaked by water for a long time. The pressure-sensitive alarm 30 is a commercially available product. The pressure-sensitive alarm 30 comprises a pressure-sensitive module and a beeping module electrically connected to each other; when the acting force received by the pressure-sensitive module is greater than the preset acting force, the pressure-sensitive module will accumulate enough potential difference to make the beeping module beep to remind (alarm).

[0059] The axis O of the water inlet channel 11 coincides with the axis P of the water outlet channel 12, and the axis O of the water inlet channel 11 forms an included angle a with the axis Q of the pressure relief channel 13. In the axial direction of the pressure relief channel 13, the projection of the pressure relief inlet 131 of the pressure relief channel 13 is located within the outer periphery of the first sealing member 22, so as to achieve the plugging of the pressure relief inlet 131 of the pressure relief channel 13 by the first sealing member 22, thereby achieving the sealing of the pressure relief channel 13.
