[0046] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0047] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0048] This embodiment provides a water flow regulating device, such as Figures 1 to 6 As shown, it includes:

[0049] The housing 100 has an inlet 101 and an outlet 102.

[0050] A flow stabilizing component 200 is disposed inside the housing 100 and divides the housing 100 into a first chamber and a second chamber. The first chamber is connected to the inlet 101 and the second chamber is connected to the outlet 102. Water flows into the housing 100 from the inlet 101, passes through the flow stabilizing component 200, and flows out of the housing 100 from the outlet 102.

[0051] The flow stabilizing component 200 includes a first flow stabilizing element and a second flow stabilizing element, and there is a water passage between the first flow stabilizing element and the second flow stabilizing element. The first flow stabilizing element and the second flow stabilizing element are movably coupled so that the opening of the water passage matches the inlet water pressure, thereby adjusting the water output of the outlet.

[0052] This invention, through the provision of a flow stabilizing assembly 200 with a first flow stabilizing element and a second flow stabilizing element, establishes a water passage between the first and second flow stabilizing elements. The movable cooperation of the first and second flow stabilizing elements allows the opening of this water passage to match the inlet water pressure. This enables accurate control of the water passage opening under constant water pressure, thereby accurately controlling the water flow rate and ensuring a stable flow rate. Furthermore, by controlling the water pressure entering from the inlet 101, the water output from the outlet 102 can be precisely controlled. Therefore, this invention solves the problem of insufficient stability in current flow stabilizing devices, leading to poor water comfort in water heaters. This embodiment is applicable to valve bodies or structures with similar valve functions. The aforementioned opening degree, also known as the water passage area, is referred to as the opening degree of the water passage.

[0053] In a preferred embodiment, such as Figures 3 to 5 As shown, the first flow stabilizer includes an elastic flow stabilizer pad 202, and the second flow stabilizer includes a base 201 and a fixing post 203. The fixing post 203 is connected to the housing 100 through the base 201, and a gap forming the second water inlet 6 is formed between the fixing post 203 and the base 201. The flow stabilizer pad 202 is fitted onto the fixing post 203. The base 201 has a protrusion on the side facing the flow stabilizer pad 202. When water flows towards the flow stabilizer pad 202, the flow stabilizer pad 202 and the base 201... The protrusion abuts against and forms a gap constituting the first water inlet 5. In this embodiment, water flows through the first water inlet 5 and the second water inlet 6 in sequence. The flow stabilizing component 200 is set inside the water flow channel, which can provide a flow stabilizing function for the water flow channel in real time. The water pressure applies an external force to the flow stabilizing pad 202 to deform it, thereby changing the gap or water flow area between it and the protrusion, so as to change the inlet flow rate of the first water inlet 5, and thus change the outlet flow rate of the second water inlet 6.

[0054] As an example, in a preferred embodiment, the protrusion includes a plurality of protruding columns 204 spaced apart circumferentially along the fixed column 203. In order to improve the sensitivity of the deformation of the flow stabilizing pad 202 to the change in the gap between the flow stabilizing pad 202 and the protruding columns 204, the heights of adjacent protruding columns 204 are different. The end face of the protruding column 204 facing the flow stabilizing pad 202 is a plane parallel to the flow stabilizing pad 202. Preferably, in order to avoid flow stabilization and reduce resistance, the protruding column 204 is preferably a cylinder. Of course, in other embodiments, the protruding column 204 can also be a square column, a multi-faceted straight column, or a curved column, etc. The height difference of the protruding columns 204 determines the flow rate of the first water outlet 5. The greater the height difference, the greater the flow rate of the first water outlet 5.

[0055] The protruding pillars 204 are symmetrically arranged along the circumference, and the height of the protruding pillars 204 decreases from both ends of the semicircle towards the middle of the semicircle; alternatively, they can be arranged as follows: Figure 5As shown, the protruding columns 204 are symmetrically arranged along the circumference. The height of the protruding columns 204 located at both ends of the semicircular arc is relatively the largest, and the height of the protruding column 204 located in the middle of the semicircular arc is relatively the smallest. Furthermore, the height change of the protruding column 204 from the middle of the semicircular arc to one end presents at least one trough and one peak, thereby preventing the flow stabilizing pad 202 from undergoing regular deformation and causing a certain degree of blockage in the first water outlet 5. Of course, those skilled in the art can also arrange the protruding columns 204 in other heights and positions based on the technical inspiration of this embodiment to achieve the same or similar technical effects. These will not be listed here. It should be noted that these can all be considered as non-creative changes to this solution.

[0056] As an example, in a specific embodiment, such as Figure 5 As shown, the protrusion includes 12 protruding pillars 204 evenly spaced along the circumference. These protruding pillars 204 are divided into 4 groups according to their height. The first group of protruding pillars 2041 has a height of 1.1 mm, the second group of protruding pillars 2042 has a height of 0.75 mm, the third group of protruding pillars 2043 has a height of 0.5 mm, and the fourth group of protruding pillars 2044 has a height of 0.25 mm.

[0057] It is important to note that the hardness of the material of the flow stabilizer 202 should not be too high or too low. If its hardness is too high, the flow limiting effect will be limited and the water pressure should not deform it. If its hardness is too low, the flow rate will decrease too much. In a preferred embodiment, the flow stabilizer 202 is made of nitrile rubber with a Brinell hardness of 65±5. It can be understood that during use, as the inlet water pressure (i.e., the water pressure flowing into the inlet 101) gradually increases from zero, the flow stabilizer 202 will only overcome the internal stress and deform when the water pressure reaches a certain value. The deformation will gradually increase, causing the opening or water flow area of ​​the first water outlet 5 to gradually decrease and eventually stabilize. Therefore, the inlet flow rate of the first water outlet 5 will gradually increase and then gradually decrease with the increase of the inlet water pressure, eventually reaching a stable state.

[0058] The stage before the deformation of the flow stabilizer 202 reaches stability can be defined as the changing stage. That is, the inlet flow rate of the first water outlet 5 changes with the change of the inlet water pressure. It can increase or decrease with the increase of water pressure, corresponding to different values ​​under different water pressures. In this way, under a certain water pressure, the inlet flow rate of the first water outlet 5 can be accurately controlled to ensure the stability of the water flow rate entering the second water outlet 6. Then, the outflow rate of the outlet 102 can be accurately controlled by controlling the inlet water pressure. In the stable stage of the deformation of the flow stabilizer 202, the inlet flow rate of the first water outlet 5 remains stable. This stage can be defined as the stable stage. That is, when the inlet water pressure changes within a certain range above a certain value and within the range of safe operation, it will not change the inlet flow rate of the first water outlet 5. In this stage, the water passage area of ​​the first water outlet 5 remains stable. Therefore, when the water pressure of the incoming water flow is greater than the preset water pressure, the inlet flow rate of the first water outlet 5 will not be affected by the change of water pressure and will remain stable.

[0059] Furthermore, the base 201 is provided with an inner through hole 205. After the fixing column 203 passes through the inner through hole 205, a gap is formed between it and the wall of the inner through hole 205, creating a second water outlet 6. To avoid eddies in the water flow, the protrusion is tangentially positioned to the wall of the inner through hole 205, allowing the water to flow evenly and stably into the first water outlet 5 and out evenly and stably from the second water outlet 6. At least two connectors 206 are evenly spaced along the circumference of the fixing column 203. The other end of the connector 206 is connected to the wall of the inner through hole 205, thereby providing stable support for the fixing column 203. It should be noted that the magnitude of the stable flow rate in the flow stabilizing component 200 of this embodiment is determined by the height of the protruding column 204, different height combinations, height differences, and the size of the gap between the fixing column 203 and the wall of the inner through hole 205 after the connectors 206 are installed. The required stable flow rate can be adjusted according to different combinations.

[0060] Furthermore, the base 201 and the housing 100 are an integral structure, which can reduce the difficulty of processing and assembly, and also improve the reliability of the product structure and the ease of installation. Of course, in other embodiments, the fixing column 203 and its connector 206, the base 201 and the housing 100 can also be designed as an integral structure.

[0061] In another preferred embodiment, a flow detection component 3 for acquiring flow rate or a temperature detection component 4 for acquiring water temperature is further provided between the inlet 101 and the outlet 102 inside the housing 100. The specific location of the flow detection component 3 and the temperature detection component 4 inside the housing 100 is not specifically limited. In a specific embodiment, in order to coordinate the rationality of the internal space arrangement of the housing 100, a flow detection component 3 is provided at the inlet 101 or a temperature detection component 4 is provided at the outlet 102 inside the housing 100. The flow detection component 3 or the temperature detection component 4 is used for communication connection with the water heater control unit. For example, Figure 2 As shown, the flow detection component 3 is located in the first cavity, and the temperature detection component 4 is located in the second cavity.

[0062] In another preferred embodiment, such as Figure 2 and Figure 6 As shown, the system also includes an adjustment component 300. A flow-blocking element 1 is disposed within the second chamber between the second water inlet 6 and the outlet 102. The flow-blocking element 1 has a third water inlet 7 and a fourth water inlet 8. The third water inlet 7 connects the second water inlet 6 and the outlet 102 to form a first water channel, and the third water inlet 7 is used to set flow resistance in the first water channel. The fourth water inlet 8 connects the third water inlet 7 and the outlet 102 to form a second water channel. The first and second water channels are connected in parallel. The adjustment component 300 is disposed in the housing 100 and connected to the fourth water inlet 8, and is used to adjust the opening and closing of the second water channel to adjust the water flow rate at the outlet 102. This embodiment forms a two-channel structure by setting the flow-blocking element 1 and the adjustment component 300. After connecting the adjustment component 300 to the fourth water inlet 8, the opening and closing of the second water channel can be adjusted through the adjustment component 300. By adjusting the opening and closing of the second water channel, the ratio of the water flow rate of the large and small water channels can be increased.

[0063] In a further preferred embodiment, the flow-blocking component 1 and the housing 100 are an integral structure. Similarly, this reduces the difficulty of processing and assembly, and also improves the reliability of the product structure and the ease of installation. For example, specifically, the flow-blocking component 1 is a T-shaped cylinder, including a first port and a second port and a third port facing each other. The second port is a fourth water outlet 8, and the adjusting component 300 is connected to the second port to control the opening and closing of the second water channel. The third port is connected to the housing 100, and the first port is connected to the outlet 102. The flow-blocking component 1 has a flow-through hole on the side wall facing the first port to form a third water outlet 7. Further, the flow-through hole includes a plurality of branch flow holes 2 evenly spaced opposite to the second water outlet 6 or the outlet 102. It should be noted that in this embodiment, the number and diameter of the branch flow holes 2 need to be adjusted and determined according to the designed initial flow resistance, and the flow area provided by the adjusting component 300 also needs to be comprehensively determined according to the designed initial flow resistance and the variation of the flow resistance.

[0064] In a further preferred embodiment, the adjusting component 300 includes a driving member 301 and a blocking member 302 drivenly connected to the driving member 301. The driving member 301 drives the blocking member 302 to switch between a conducting position and a blocking position to open or close the second water channel. It is understood that the blocking member 302 can move according to actual conditions to adjust the opening and closing of the second water channel.

[0065] When a large flow rate is required, the barrier 302 can switch between the open position and the closed position to open the second water channel, thereby reducing the flow resistance of the second water outlet 6. At this time, the water in the first chamber can flow from the first water outlet 5, the second water outlet 6, and the third water outlet 7 to the outlet 102 in sequence. At the same time, it can also flow from the first water outlet 5, the second water outlet 6, the third water outlet 7, and the fourth water outlet 8 to the outlet 102 in sequence, realizing the function of dual-channel flow to the outlet 102, increasing the water flow area of ​​the second chamber, and thus increasing the water flow rate at the outlet 102.

[0066] When the flow rate requirement is not high, the blocking component 302 moves to block the second water channel. At this time, the water in the first chamber can only flow from the first water inlet 5, the second water inlet 6, and the third water inlet 7 to the outlet 102 in sequence, which reduces the water flow area of ​​the second chamber, thereby reducing the water flow rate entering the second chamber and thus reducing the water flow rate at the outlet 102.

[0067] The specific structure of the regulating component 300 can be determined according to the actual situation. The barrier 302 only needs to be movable, and its movement should be able to open or close the second water channel to regulate the number of flow channels from the first chamber to the second chamber. For example, the regulating component 300 can be a structure where a solenoid valve drives the movement of the barrier 302, or a structure where a cylinder or stepper motor drives the movement of the barrier 302. The barrier 302 can be a partition or a barrier membrane, etc.

[0068] In one embodiment of the present invention, the driving component 301 is a water circuit electromagnetic shut-off valve, and the blocking component 302 is fixedly connected to the valve core of the electromagnetic shut-off valve. The electromagnetic shut-off valve controls the movement of the valve core to drive the blocking component 302 to move. The use of an electromagnetic shut-off valve improves the stability of the adjustment component 300.

[0069] Through testing, the embodiments of the present invention can increase the water flow ratio of the large and small channels before and after the second water channel is opened and closed to 5.7 / 10, which is nearly three times higher than the existing gas water heaters that use a two-channel water servo component with a water flow ratio of 2.5 / 10-3 / 10 for adjusting the water flow of the large and small channels.

[0070] In addition, an embodiment of a gas water heater is provided, including the aforementioned water flow regulating device.

[0071] This embodiment uses the above-mentioned water flow regulating device and has the beneficial effects of the above-mentioned water flow regulating device.

[0072] Furthermore, when a gas water heater is equipped with a water flow regulating device featuring the regulating component 300, the ratio of water flow regulation between the two channels using the two-channel water servo component can be improved, enhancing the constant temperature effect of pressurization or secondary activation, thereby improving water comfort. In practical applications, the condition where the regulating component 300 isolates the second water channel is suitable for summer when water temperature requirements are not high, increasing water flow and improving bathing comfort; while the condition where the regulating component 300 opens the second water channel is suitable for winter when water temperature requirements are higher.
