However, the embodiments cited are not intended to limit the present invention.

[0047] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used in the present invention are for illustrative purposes only.

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

[0049] The housing 100 has a water inlet 101 and a water outlet 102;

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

[0051] The flow stabilizing component 200 includes a first flow stabilizing member and a second flow stabilizing member, and a water passage is provided between the first flow stabilizing member and the second flow stabilizing member. The first flow stabilizing member and the second flow stabilizing member cooperate flexibly to match the opening of the water passage with the water pressure of the water inlet, thereby adjusting the water output of the water outlet.

[0052] The embodiment of the present invention is provided with a flow stabilizing component 200 having a first flow stabilizing member and a second flow stabilizing member, wherein a water passage is provided between the first flow stabilizing member and the second flow stabilizing member, and the first flow stabilizing member and the second flow stabilizing member can cooperate to make the opening of the water passage match the water pressure of the water inlet, so that the opening of the water passage can be accurately controlled under a certain water pressure, and then the water flow of the water passage can be accurately controlled, and the water flow can be ensured to be stable, and then the water output of the water outlet 102 can be accurately controlled by controlling the water pressure of the water flow entering from the water inlet 101, so that the problem of insufficient stability of the current flow stabilizing device, which leads to poor water outlet comfort of the water heater, can be solved. This embodiment can be applied to a valve body or a structure with similar valve function, wherein the above-mentioned opening, that is, the degree of opening, is also called the water flow area of ​​the water passage.

[0053] In a preferred embodiment, Figures 3 to 5 As shown, the first flow stabilizing member includes an elastic flow stabilizing pad 202, and the second flow stabilizing member includes a base 201 and a fixing column 203. The fixing column 203 is connected to the housing 100 through the base 201, and a gap constituting a second water outlet 6 is formed between the fixing column 203 and the base 201; the flow stabilizing pad 202 is sleeved on the fixing column 203, and the base 201 is provided with a protrusion on a side facing the flow stabilizing pad 202. When water flows toward the flow stabilizing pad 202, the flow stabilizing pad 202 and the water flow stabilizing pad 202 are in contact with each other. The raised portion abuts against and forms a gap constituting the first water outlet 5. In this embodiment, water flows through the first water outlet 5 and the second water outlet 6 in sequence. The flow stabilizing component 200 is arranged 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 cause it to deform, thereby changing the gap or water flow area between it and the raised portion, thereby achieving the purpose of changing the water inlet flow rate of the first water outlet 5, and then changing the water outlet of the second water outlet 6.

[0054] As an example, in a preferred embodiment, the raised portion includes a plurality of raised columns 204 arranged at intervals along the circumference of the fixed column 203. In order to increase the sensitivity of the gap change between the flow stabilizing pad 202 and the raised columns 204 to the deformation of the flow stabilizing pad 202, the heights of adjacent raised columns 204 are different, and the end surface of the raised column 204 facing the flow stabilizing pad 202 is a plane parallel to the flow stabilizing pad 202. Preferably, in order to avoid stabilizing flow and reduce resistance, the raised column 204 is preferably a cylinder. Of course, in other embodiments, the raised column 204 may also be a square column, a multi-faceted straight column or a curved column, etc.; the height difference of the raised column 204 determines the flow rate of the first water outlet 5, and the greater the height difference, the greater the flow rate of the first water outlet 5.

[0055] The raised columns 204 are symmetrically arranged along the circumference, and the height of the raised columns 204 decreases from the two ends of the semicircular arc to the middle of the semicircular arc; Figure 5As shown, the raised columns 204 are symmetrically arranged along the circumference, the height of the raised columns 204 located at both ends of the semicircular arc is relatively the largest, and the height of the raised columns 204 located in the middle of the semicircular arc is relatively the smallest, and the height change of the raised columns 204 from the middle of the semicircular arc to one end thereof presents at least one trough and one peak, thereby avoiding the regular deformation of the flow stabilizing pad 202 and causing a certain degree of blockage in the first water outlet 5. Of course, those skilled in the art can also arrange the raised columns 204 in other heights and positions under the technical enlightenment of this embodiment to achieve the same or similar technical effects, which will not be listed here one by one. It should be noted that these can all be considered as changes to the non-creative labor performed on this solution.

[0056] As an example, in a specific embodiment, Figure 5 As shown, the raised portion includes 12 raised columns 204 evenly spaced along the circumference, and these raised columns 204 are divided into 4 groups according to their heights, wherein the height of the first group of raised columns 2041 is 1.1 mm, the height of the second group of raised columns 2042 is 0.75 mm, the height of the third group of raised columns 2043 is 0.5 mm, and the height of the fourth group of raised columns 2044 is 0.25 mm.

[0057] It should be noted that the hardness of the material of the flow-stabilizing pad 202 should not be too large or too small. If its hardness is too high, the flow-limiting effect is limited and the water pressure should not deform it. If its hardness is too low, the flow rate will be reduced too much. In a specific preferred embodiment, the flow-stabilizing pad 202 is made of nitrile rubber, and the Brinell hardness is preferably 65±5. It can be understood that during use, as the inlet water pressure (i.e., the water pressure of water flowing into the water inlet 101) gradually increases from zero, the flow-stabilizing pad 202 will overcome the internal stress of the flow-stabilizing pad 202 and deform only when the water pressure reaches a certain value, and then the deformation gradually increases, so that the opening or water flow area of ​​the first water outlet 5 gradually decreases and finally stabilizes. Therefore, the water inlet flow rate of the first water outlet 5 will gradually increase with the increase of the inlet water pressure, then gradually decrease and finally reach a stable change process.

[0058] The stage before the deformation of the flow-stabilizing pad 202 reaches stability can be defined as a changing stage, that is, the water inlet flow rate of the first water outlet 5 changes with the change of the inlet water pressure, and can increase with the increase of water pressure, or can decrease with the increase of water pressure, and corresponds to different values ​​under different water pressures. In this way, the water inlet flow rate of the first water outlet 5 can be accurately controlled under a constant water pressure to ensure the stability of the water flow entering the second water outlet 6, and then the water output of the water outlet 102 can be accurately controlled by controlling the inlet water pressure; in the stable stage of the deformation of the flow-stabilizing pad 202, the water inlet flow rate of the first water outlet 5 remains stable, and this stage can be defined as a stable stage, that is, when the inlet water pressure changes above a certain value and within the water pressure range that can operate safely, the water inlet flow rate of the first water outlet 5 will not change, and the water flow area of ​​the first water outlet 5 remains stable at this stage, so that when the water pressure of the incoming water flow is greater than the preset water pressure, the water inlet flow rate of the first water outlet 5 will not be affected by the change in water pressure and remain stable.

[0059] Furthermore, the base 201 is provided with an inner through hole 205, and a gap of the second water outlet 6 is formed between the fixed column 203 and the wall of the inner through hole 205 after the fixed column 203 passes through the inner through hole 205. In order to avoid eddy currents in the water flow, the raised portion is arranged tangent to the wall of the inner through hole 205, so that the water flow can flow into the first water outlet 5 evenly and stably, and flow out from the second water outlet 6 evenly and stably. The fixed column 203 is evenly spaced along the circumference, and at least two connecting members 206 are arranged, and the other end of the connecting member 206 is connected to the wall of the inner through hole 205, so as to play a role in stabilizing support for the fixed column 203. It should be noted that the size of the steady flow rate in the steady flow assembly 200 of this embodiment is jointly determined by the height of the raised column 204, different height combinations, height difference, and the size of the gap between the fixed column 203 and the wall of the inner through hole 205 after the connection member 206 is arranged. The corresponding required steady flow rate can be adjusted according to different combinations.

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

[0061] In another preferred embodiment, a flow detection component 3 for obtaining flow conditions or a temperature detection component 4 for obtaining water temperature is further provided between the water inlet 101 and the water outlet 102 in the shell 100, and the specific positions of the flow detection component 3 and the temperature detection component 4 in the shell 100 are not specifically limited; in a specific embodiment, in order to coordinate the rationality of the internal space setting of the shell 100, a flow detection component 3 is provided at the water inlet 101 in the shell 100 or a temperature detection component 4 is provided at the water outlet 102 in the shell 100, and the flow detection component 3 or the temperature detection component 4 is used to communicate with the water heater control unit. For example, Figure 2 As shown, the flow detection component 3 is arranged in the first cavity, and the temperature detection component 4 is arranged in the second cavity.

[0062] In another preferred embodiment, Figure 2 and Figure 6 As shown, it also includes an adjustment component 300, a flow blocker 1 located between the second water port 6 and the water outlet 102 is arranged in the second chamber, the flow blocker 1 is provided with a third water port 7 and a fourth water port 8, the third water port 7 connects the second water port 6 and the water outlet 102 to form a first water channel, the third water port 7 is used to set a flow resistance in the first water channel, the fourth water port 8 connects the third water port 7 and the water outlet 102 to form a second water channel, the first water channel is connected in parallel with the second water channel, and the adjustment component 300 is arranged on the housing 100 and connected to the fourth water port 8, and is used to adjust the on-off of the second water channel to adjust the water output at the water outlet 102. In this embodiment, a two-channel structure can be formed by arranging the flow blocker 1 and the adjustment component 300. After the adjustment component 300 is connected to the fourth water port 8, the on-off of the second water channel can be adjusted by the adjustment component 300. By adjusting the on-off of the second water channel, the purpose of increasing the water volume flow rate adjustment ratio of the water volume channel can be achieved.

[0063] In a further preferred embodiment, the baffle 1 and the shell 100 are an integrated structure. Similarly, the difficulty of processing and assembly can be reduced, and the reliability of the product structure and the convenience of installation can be improved. As an example, specifically, the baffle 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 adjustment component 300 is connected to the second port to control the on-off of the second water channel, the third port is connected to the shell 100, and the first port is connected to the water outlet 102; the baffle 1 is provided with a flow hole on the side wall facing the first port to form a third water outlet 7, further, the flow hole includes a plurality of bypass holes 2 evenly spaced opposite to the second water outlet 6 or the water outlet 102. It should be noted that the number and diameter of the bypass holes 2 in this embodiment need to be determined according to the designed initial flow resistance, and the flow area that the adjustment component 300 can provide also needs to be comprehensively determined according to the designed initial flow resistance and the amplitude of the flow resistance.

[0064] In a further preferred embodiment, the adjustment component 300 includes a driving member 301 and a blocking member 302 drivingly connected to the driving member 301, and the driving member 301 drives the blocking member 302 to switch between the conducting position and the blocking position to conduct or block the second water channel; it can be 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 blocking member 302 is movably switched between the conducting position and the blocking position to conduct the second water channel, thereby reducing the flow resistance of the second water port 6. At this time, the water in the first chamber can flow from the first water port 5, the second water port 6, and the third water port 7 to the water outlet 102 in sequence, and can also flow from the first water port 5, the second water port 6, the third water port 7, and the fourth water port 8 to the water outlet 102 in sequence, realizing the function of dual-channel flow to the water outlet 102, increasing the water flow area of ​​the second chamber, and further realizing the function of increasing the water flow rate at the water outlet 102;

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

[0067] The specific structure of the regulating component 300 can be determined according to the actual situation, wherein the blocking member 302 only needs to be movable, and the movement of the blocking member 302 can realize the opening or closing of the second water channel to adjust the number of flow channels for water to flow from the first chamber to the second chamber. For example, the regulating component 300 can be a structure in which the electromagnetic valve drives the blocking member 302 to move, or a structure in which the cylinder or stepper motor drives the blocking member 302 to move, and the blocking member 302 can be a structure such as a partition or a barrier film.

[0068] In one embodiment of the present invention, the driving member 301 is a water circuit electromagnetic stop valve, the blocking member 302 is fixedly connected to the valve core of the electromagnetic stop valve, and the electromagnetic stop valve controls the movement of the valve core to drive the movement of the blocking member 302. The electromagnetic stop valve control is adopted to improve the stability of the adjustment of the adjustment component 300.

[0069] After testing, it was found that the embodiment 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 heater using a two-channel water servo component with a water volume and a water flow adjustment ratio of 2.5 / 10-3 / 10.

[0070] In addition, an embodiment of a gas water heater is provided, comprising 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] When the gas water heater is equipped with a water flow regulating device having a regulating component 300, the water flow regulating ratio of the two-way water servo component of the gas water heater can be improved, and the constant temperature effect of the boost or secondary opening can be improved, thereby improving the comfort of the water output. In actual application, the condition where the regulating component 300 blocks the second water channel is suitable for summer when the water temperature requirement is not high, increasing the water flow and improving the comfort of bathing; while the condition where the regulating component 300 opens the second water channel is suitable for winter when the water temperature requirement is high.
