For example, the water outlet portion 150 extends along a horizontal direction, the water outlet channel 140 is disposed in the water outlet portion 150, and the water outlet 120 is disposed at one end of the water outlet portion 150.

In some embodiments of the present invention, as shown in fig. 2-4, the pressure-sensitive flow regulating assembly 300 includes a positioning socket 310, a positioning cap 320, and a pressure-sensitive member 330.
A plurality of positioning seat through holes 311 spaced along the circumferential direction of the positioning seat 310 are formed in the positioning seat 310. The positioning cover 320 is installed on the positioning seat 310 and below the positioning seat 310, and a plurality of positioning cover through holes 321 spaced along the circumferential direction of the positioning cover 320 and a flow guiding column 323 extending into the positioning seat through hole 311 are arranged on the positioning cover 320. The pressure sensing piece 330 is variable according to pressure shape, for example, the pressure sensing piece 330 may be a rubber ring, the pressure sensing piece 330 is sleeved on the flow guiding column 323 and is located between the positioning seat 310 and the positioning cover 320, a pressure flow adjusting hole 430 respectively communicated with the positioning seat through hole 311 and the positioning cover through hole 321 is defined between an inner circumferential surface of the pressure sensing piece 330 and an outer circumferential surface of the flow guiding column 323, and the pressure sensing piece 330 adjusts a cross-sectional area of the pressure flow adjusting hole 430 through deformation of the pressure sensing piece 330.
Specifically, when the water pressure in the water inlet flow passage 130 is high, the water acts on the pressure sensing member 330 through the positioning cover hole 321, the pressure sensing member 330 deforms toward the guide post 323, the cross-sectional area of the pressure/flow rate adjusting hole 430 decreases, and the water flow rate decreases.
When the water pressure in the water inlet flow passage 130 is low, the pressure sensing member 330 is restored to the original shape, and the cross-sectional area of the pressure flow rate adjustment hole 430 is enlarged, thereby increasing the water flow rate.
It will be understood by those skilled in the art that the pressure sensing member 330 surrounds the outer side of the guide post 323, the pressure-flow rate adjustment hole 430 is defined by the inner circumferential surface of the pressure sensing member 330 and the outer circumferential surface of the stroke sleeve 220, and when the pressure sensing member 330 is subjected to a large water pressure, the pressure sensing member 330 is deformed toward the guide post 323 (i.e., the pressure sensing member 330 is crushed), thereby reducing the cross-sectional area of the pressure-flow rate adjustment hole 430. When the pressure-sensitive member 330 receives a small water pressure, the pressure-sensitive member 330 recovers its shape, and thus the cross-sectional area of the pressure-flow rate adjusting hole 430 increases.
Alternatively, as shown in fig. 3 and 4, an inner circumferential surface of the positioning seat 310 is provided with a fitting ring groove extending along a circumferential direction of the positioning seat 310, and an outer edge of the positioning cover 320 is fitted in the fitting ring groove.

The turbine blades are rotatably provided on the mount 410. A magnetic rotor 430 is rotatably disposed within the mount 410 adjacent the turbine blades. The hall element 440 is mounted on the outer wall of the housing 100.
Specifically, when the turbine blade rotates, the turbine blade drives the nearby water flow to rotate, the rotating water flow pushes the magnetic rotor 430 to rotate, and the hall element 440 senses the rotation of the magnetic rotor 430 to determine the water flow and feeds the water flow back to the control system 70 by using a control line.

The operation of the gas water heater 1 according to the embodiment of the present invention will be described.
As shown in fig. 1 to 4, when water flows through the automatic flow rate adjusting device 10 at a certain temperature and the pressure of the water increases, the pressure sensing member 330 deforms to change the gap between the pressure sensing member and the flow guiding column 323, so as to change the cross-sectional area of the pressure/flow rate adjusting hole 430, thereby stabilizing the flow. The temperature sensing bulb 330 senses the temperature of the water outlet channel 140 and linearly expands or contracts, so as to push the stroke sleeve 220 to move, change the position of the opening adjusting head 222 in the conical hole, change the opening of the temperature and flow adjusting hole 250, and further change the water flow. When water flows through the turbine blades, the water flow rotates to push the magnetic rotor 430 to rotate, the Hall element 440 senses the rotation of the magnetic rotor 430, and the water flow is judged and fed back to the control system. The control system controls the gas supply proportion of the gas control system according to the water flow after the feedback adjustment of the automatic flow adjusting device 10, thereby controlling the combustion load of the combustion system and enabling the outlet water to reach the ideal temperature.

Therefore, the outlet temperature is constant, the fluctuation is small, and the flow is stable when the water consumption and the water pressure at multiple points are too high. Compared with a stepping motor type water proportional valve, the reaction time is greatly shortened because repeated judgment and calculation of a controller are not needed. The deformation control through temperature sensing package 330 is intake flow and is stable to reach the effect of stationary flow, from the source automatic control intake flow, and need not just carry out water flow regulation according to using the rear end feedback, can feed back the water flow after adjusting simultaneously, and the gas heater inner space's of being convenient for overall layout.
