The paraffin temperature sensing assembly 20 is disposed in the housing 10, and the paraffin temperature sensing assembly 20 can control the opening of the water outlet 102 according to the ambient temperature. When the water temperature entering the shell 10 is low, the paraffin temperature sensing assembly 20 can reduce the opening of the water outlet 102, so that the water flow entering the heat exchanger 50 of the water heater 200 is reduced; when the temperature of the water entering the housing 10 increases, the paraffin temperature sensing assembly 20 can increase the opening of the water outlet 102, thereby increasing the flow rate of water entering the heat exchanger 50.

In addition, by providing the flow feedback device 30 also in the housing 10, the flow rate of the water flowing through the housing 10 can be fed back to the controller 70 of the water heater 200, thereby ensuring that the water heater 200 reaches a desired operating state. In addition, since the flow feedback device 30 is disposed within the housing 10, the water entering the housing 10 will first pass through the flow stabilizing assembly 40.

The bulb 21 is also provided with a push rod mounting hole 212, and the push rod mounting hole 212 is arranged in the direction of the accommodating cavity 211 facing the water outlet 102.
The push rod 22 is fitted in the push rod mounting hole 212, and the push rod 22 is relatively movable in the axial direction of the bulb 21. Compared with the technical scheme that the push rod 22 is not arranged, the temperature sensing bulb 21 is directly used for driving the travel rod 23, the push rod 22 can be firstly arranged in the push rod mounting hole 212 during mounting, and then the whole body formed by the push rod 22 and the temperature sensing bulb 21 is arranged in the shell 10, so that the paraffin temperature sensing assembly 20 is convenient to manufacture and mount, the filling and packaging of the temperature sensing bulb 21 are convenient, and the tightness and the temperature sensing effect of the paraffin temperature sensing assembly 20 can be improved.

Specifically, when the temperature of water passing through the casing 10 increases, the paraffin temperature sensing material expands, the travel rod 23 moves rightwards under the pushing of the push rod 22, and drives the flow limiting plug 24 to move, so that the opening of the water outlet 102 becomes larger, and the water flow passing through the water outlet 102 increases; when the water inlet temperature is lower, the paraffin temperature sensing material contracts, the travel rod 23 moves leftwards under the pushing of the push rod 22, the flow limiting plug 24 is driven to move leftwards, the opening of the water outlet 102 is reduced, and the water flow passing through the water outlet 102 is reduced.
In some examples, the stroke rod 23 and the push rod 22 are manufactured separately, and compared with the technical scheme that the push rod 22 is not arranged, the paraffin temperature sensing assembly 20 can be conveniently applied to the shells 10 of the flow regulation feedback devices 100 with different models by directly utilizing the temperature sensing bag 21 to drive the stroke rod 23, and modular standardized production of the stroke rod 23 and the push rod 22 is facilitated. The paraffin temperature sensing assembly 20 is arranged between the water source of the water heater 200 and the heat exchanger 50, which is beneficial to the accurate control of the water heater 200 on the water inflow.
According to an example of the present invention, the housing 10 further includes an elastic member 15, and the elastic member 15 is sleeved on the travel rod 23, so as to drive the travel rod 23 to drive the flow limiting plug 24 to move in a direction of reducing the opening of the water outlet 102.

Specifically, when the temperature of the water passing through the bulb 21 is higher, the paraffin temperature sensing material expands in volume, so as to push the push rod 22 and the travel rod 23 to overcome the elastic force of the pressure spring, when the temperature of the water passing through the bulb 21 is lower, the paraffin temperature sensing material reduces in volume, the travel rod 23 pushes the push rod 22 to reset under the elastic force of the pressure spring, the pressure spring provides a driving force for the movement of the travel rod 23, the travel rod 23 can be automatically reset, meanwhile, the movement of the travel rod 23 is more sensitive, the movement stability of the flow limiting plug 24 is ensured, and therefore the stability of the water flow in the flow regulating feedback device 100 is ensured.
As shown in fig. 4, in some examples, the water outlet 102 may form a hole seat with a tapered cross-sectional area, the size of the tapered hole increases gradually from left to right, the shape of the flow-limiting plug 24 is matched with the shape of the water outlet 102, that is, the cross section of the flow-limiting plug 24 is also tapered, and the tapered surface of the flow-limiting plug 24 is parallel to the tapered surface of the water outlet 102, so that the flow-limiting plug 24 is not blocked in the moving process, and meanwhile, the opening of the water outlet 102 may be uniformly changed, so that the flow-regulating feedback device 100 is convenient for controlling the water flow.
In some specific examples, the housing 10 also has a water outlet seat 25 therein. The right end of the shell 10 is provided with a boss, the right end of the water outlet seat 25 is stopped against the left side of the boss of the valve body 51, the water outlet 102 is formed on the water outlet seat 25, a first sealing ring 13 is arranged between the outer peripheral surface of the water outlet seat 25 and the inner peripheral surface of the shell 10, the first sealing ring 13 can fix the water outlet seat 25, the water outlet seat 25 is prevented from moving relatively, and meanwhile, the tightness between the water outlet seat 25 and the shell 10 is ensured.

Specifically, the inflow water with a certain temperature firstly flows through the pressure sensing ring 43, when the inflow water pressure is increased, the inflow water flow is increased, and the pressure sensing ring 43 expands, so that the opening degree of the steady flow inlet 412 is reduced, namely the cross section area of the steady flow inlet 412 is reduced, and the water flow flowing into the flow regulating feedback device 100 is kept constant; when the inflow pressure is reduced, the inflow flow is reduced, and the pressure sensing ring 43 is contracted, thereby increasing the opening of the steady flow inlet 412, i.e., increasing the cross-sectional area of the steady flow inlet 412, so that the flow rate of water flowing into the flow adjustment feedback device 100 is maintained at a preset flow rate value and is maintained unchanged.
