[0007] A gas distribution pipe, on which a gas outlet and a plurality of gas inlets are provided;

[0008] The regulating mechanism comprises an electromagnetic coil arranged on the gas distribution pipe and a regulating component arranged inside the gas distribution pipe and close to a gas inlet and having magnetic properties;

[0009] a limit block, arranged inside the gas distribution pipe and located at at least one side of the gas inlet, so as to limit the range of movement of the adjustment component along the extension direction of the gas distribution pipe;

[0010] Wherein, after the electromagnetic coil is energized, it can drive the regulating component to move to adjust the cross-sectional size of the gas inlet, so as to change the total gas displacement of the gas outlet, and the regulating component can completely open and close the gas inlet.

[0011] In the technical solution, the cross-sectional size of the gas inlet is changed by the regulating action of the electromagnetic coil and the magnetic regulating assembly, so that the gas supply can be flexibly adjusted as needed to meet different combustion requirements. At the same time, the gas distribution device has a high degree of control performance and can quickly switch the gas supply to meet different combustion requirements. In short, this gas distribution device has the characteristics of adjustable and precise control, so that it can realize gas supply and combustion control of different requirements in various combustion applications.

[0012] Preferably, the gas distribution pipe comprises a first gas branch and a main gas pipeline for gas to enter, the first gas branch and the main gas pipeline are connected through a first chamber, and the gas outlet is arranged on the first chamber;

[0013] Among them, the regulating component is arranged inside the first chamber and close to the gas outlet end of the main gas pipeline, a regulating space is formed between the outer edge of the regulating component and the inner wall surface of the first chamber, and the gas outlet end of the first gas branch is arranged at a position away from the regulating space.

[0014] In the present technical solution, this structural form is adopted, which helps to more effectively control the flow and distribution of gas. In addition, the gas outlet end of the main gas pipeline and the gas outlet end of the first gas branch are staggered, which helps to more evenly guide the gas to different gas outlets and avoid unnecessary mixing or turbulence.

[0015] Preferably, there are multiple gas outlets, and at least one of the gas outlets is arranged in the adjustment space and can change the gas discharge volume of the gas outlet by adjusting the cross-sectional size of the gas outlet end of the total gas pipeline blocked by the adjustment component.

[0016] In the present technical solution, this structural form is adopted, so that the regulating component can independently adjust the cross-sectional size of the gas outlet, and can perform precise adjustment as needed, without affecting the gas entering the first chamber from the outlet end of the first gas branch and then being discharged from other gas outlets. Only by adjusting at least one gas outlet, the gas distribution device can meet different gas needs.

[0017] Preferably, the adjustment component comprises:

[0018] A fixed shaft, the extension direction of the fixed shaft is the same as the moving direction of the adjustment assembly, and one end of the fixed shaft is fixed to the inner wall surface of the gas distribution pipe;

[0019] Two magnetic members, including a first magnetic member and a second magnetic member, wherein the first magnetic member is fixedly disposed on an end of the fixed shaft away from the inner wall surface of the gas distribution pipe, and the second magnetic member is sleeved on the fixed shaft and can move along the extension direction of the fixed shaft;

[0020] an elastic member, sandwiched between the first magnetic member and the second magnetic member;

[0021] The sealing member is at least partially sleeved on the elastic member.

[0022] In the present technical solution, one end of the fixed shaft is fixed on the inner wall surface of the gas distribution pipe, which ensures the stability of the movement of the adjustment component and prevents the movement of the adjustment component from deviating from its required range of movement. In addition, the setting of the two magnetic parts and the electromagnetic interaction between them and the electromagnetic coil can control the position of the adjustment component, thereby changing the cross-sectional size of the gas outlet. Furthermore, the elastic part is located between the first magnetic part and the second magnetic part, and is used to provide the two magnetic parts with a reverse force or a rebound force, that is, to return to the required position, so as to ensure that the position of the adjustment component is stable and can move along the fixed axis when necessary. At the same time, the setting of the sealing part helps to ensure the sealing of the adjustment component when it at least partially blocks the gas outlet, avoiding gas leakage and reducing the accuracy and efficiency of gas control. Therefore, this structural form of the adjustment component can be used to achieve precise control of the gas supply, meet different combustion requirements, and ensure the reliability and stability of the movement of the adjustment component in the gas distribution pipe.

[0023] Preferably, the height of the sealing member along a direction perpendicular to the movement direction of the regulating assembly is not lower than the maximum height of the gas outlet.

[0024] In the present technical solution, this structural form is adopted, which can effectively prevent leakage when the regulating component at least partially blocks the gas outlet, thereby improving the accuracy and efficiency of gas control.

[0025] Preferably, when the electromagnetic coil is not energized, the first magnetic member abuts against the limit block, the elastic member is in a relaxed state and drives the sealing member to at least partially cover the gas outlet;

[0026] When a positive current is passed through the electromagnetic coil, the second magnetic member can be attracted to move toward one side of the first magnetic member along the extension direction of the fixed axis until there is no overlapping area between the sealing member and the gas outlet;

[0027] When a reverse current flows through the electromagnetic coil, the second magnetic member can be repelled and moved along the extension direction of the fixed axis toward a side away from the first magnetic member until the sealing member completely covers the gas outlet.

[0028] In this technical solution, by controlling the way the electromagnetic coil is energized, the position of the regulating component can be accurately controlled to achieve control of gas distribution. In addition, by controlling the energization state of the electromagnetic coil, the gas supply can be quickly changed, and the gas supply amount can be flexibly adjusted to meet different combustion needs.

[0029] Preferably, the electromagnetic coil is arranged in the gas distribution pipe at a position close to the regulating assembly.

[0030] In the present technical solution, since the electromagnetic coil needs to influence and drive the position of the regulating component, placing the electromagnetic coil close to the regulating component can achieve more precise control of the regulating component by the electromagnetic coil. The regulating component can receive the electromagnetic force generated by the electromagnetic coil more quickly and adjust the position of the regulating component relative to the gas outlet in time, thereby changing the gas supply.

[0031] Preferably, there are two limit blocks, which are arranged on both sides of the gas inlet along the moving direction of the adjustment assembly, and the distance between the two limit blocks is not less than the maximum inner diameter of the gas inlet.

[0032] In the present technical solution, this structural form can effectively limit the movement range of the adjustment component, ensuring that the adjustment component can only move within the specified range, preventing excessive movement or exceeding the required range and causing failure of adjustment of the gas outlet cross-sectional size.

[0033] Preferably, a nozzle is provided at the gas outlet and is arranged toward the combustion chamber box.

[0034] In the present technical solution, by setting the nozzle, the gas can be sprayed in a specified direction, which helps to directly guide the gas into the combustion area of ​​the combustion chamber box to achieve more efficient combustion.

[0035] A gas water heater comprises a combustion chamber box and a gas distribution device as described above for spraying gas to the combustion chamber box.

[0036] In the present technical solution, the gas water heater adopts this structural form, which can realize automatic adjustment of the gas flow according to different seasons such as summer and winter, thereby adjusting the working range of the heating capacity of the gas water heater.

[0037] The positive and progressive effects of the utility model are:

In short, this gas distribution device has the characteristics of adjustable and precise control, so that it can realize gas supply and combustion control with different requirements in various combustion applications.

[0064] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0065] [Example 1]

[0066] like Figure 1-Figure 4 As shown, Embodiment 1 discloses a gas distribution device 100, and the gas sprayed by the gas distribution device 100 is directly used for combustion in the combustion chamber box.

[0067] The gas distribution device 100 includes a gas distribution pipe 200, an adjustment mechanism 300 and a stopper 21. The gas distribution pipe 200 is provided with a gas outlet and a plurality of gas inlets. The adjustment mechanism 300 includes an electromagnetic coil 31 disposed on the gas distribution pipe 200 and an adjustment component 32 disposed inside the gas distribution pipe 200 and close to any gas inlet. The adjustment component 32 is magnetic and can be attracted and repelled by the electromagnetic force generated by the electromagnetic coil 31, so that the adjustment component 32 can move inside the gas distribution pipe 200 along the extension direction of the gas distribution pipe 200. At the same time, the stopper 21 is disposed inside the gas distribution pipe 200 and located on at least one side of the gas inlet to limit the range of movement of the adjustment component 32 along the extension direction of the gas distribution pipe 200.

[0068] Specifically, after the electromagnetic coil 31 is energized, it can drive the adjustment component 32 to move to adjust the cross-sectional size of the gas inlet, so as to change the total gas displacement of the gas outlet. The adjustment component 32 can completely open and close the gas inlet.

[0069] In this embodiment, the cross-sectional size of the gas inlet is changed by adjusting the electromagnetic coil 31 and the magnetic adjusting component 32, so that the gas supply can be flexibly adjusted as needed to meet different combustion requirements. At the same time, the gas distribution device 100 has a high degree of controllability and can quickly switch the gas supply to meet different combustion requirements. In short, the gas distribution device 100 has adjustable and precisely controlled characteristics, so that it can achieve gas supply and combustion control of different requirements in various combustion applications.

[0070] Preferably, if Figure 1 and Figure 2 As shown, the gas distribution pipe 200 includes a first gas branch 22, a second gas branch 23 and a main gas pipeline 24 for supplying gas, the first gas branch 22 and the main gas pipeline 24 are connected through a first chamber 25, the second gas branch 23 and the main gas pipeline 24 are connected through a second chamber 26, and the gas outlet is arranged on the first chamber 25 and the second chamber 26.

[0071] Among them, the regulating component 32 is arranged inside the first chamber 25 and close to the gas outlet end of the main gas pipeline 24, and a regulating space is formed between the outer edge of the regulating component 32 and the inner wall surface of the first chamber 25. The gas outlet end of the first gas branch 22 is arranged at a position away from the regulating space, that is, the gas outlet end of the main gas pipeline 24 and the gas outlet end of the first gas branch 22 are staggered.

[0072] In this embodiment, this structural form helps to more effectively control the flow and distribution of gas, and the gas outlet end of the main gas pipeline 24 and the gas outlet end of the first gas branch 22 are staggered, which helps to more evenly guide the gas to different gas outlets and avoid unnecessary mixing or turbulence.

[0073] Furthermore, there are multiple gas outlets, and the multiple gas outlets are arranged in sequence and spaced apart along the extending direction of the first chamber 25 and the second chamber 26 .

[0074] In addition, at least one gas outlet is arranged in the adjustment space. In the present embodiment, a gas outlet is provided between the gas outlet end of the total gas pipeline 24 and the inner wall surface of the first chamber 25. Therefore, the gas discharge volume of the clamped gas outlet can be changed by adjusting the cross-sectional size of the gas outlet end of the total gas pipeline 24 blocked by the adjustment component 32.

[0075] In the present embodiment, this structural form is adopted, so that the adjustment component 32 can independently adjust the cross-sectional size of the gas outlet, and can perform precise adjustment as needed, without affecting the gas entering the first chamber 25 from the gas outlet end of the first gas branch 22 and being discharged from other gas outlets. Only by adjusting at least one gas outlet, the gas distribution device 100 can meet different gas needs.

[0076] like Figure 4 As shown, the adjustment assembly 32 includes a fixed shaft 321 , two magnetic members 322 , an elastic member 323 and a sealing member 324 .

[0077] Specifically, the extension direction of the fixed shaft 321 is the same as the moving direction X of the adjusting assembly, and one end of the fixed shaft 321 is fixed on the inner wall surface of the gas distribution pipe 200, that is, fixedly arranged on the inner wall surface of the first chamber 25, which ensures the stability of the movement of the adjusting assembly 32 and prevents the movement of the adjusting assembly 32 from deviating from its required moving range.

[0078] The two magnetic parts 322 include a first magnetic part 3221 and a second magnetic part 3222. The first magnetic part 3221 is fixedly arranged on one end of the fixed shaft 321 away from the inner wall surface of the gas distribution pipe 200, and the second magnetic part 3222 is sleeved on the fixed shaft 321 and can move along the extension direction of the fixed shaft 321. The setting of the two magnetic parts 322 and the electromagnetic interaction between them and the electromagnetic coil 31 can control the position of the adjustment component 32, thereby changing the cross-sectional size of the gas outlet.

[0079] The elastic member 323 is sandwiched between the first magnetic member 3221 and the second magnetic member 3222 to provide the two magnetic members 322 with a reverse force or a rebound force to return to the desired position, thereby ensuring that the position of the adjustment component 32 is stable and can be moved along the fixed axis 321 when needed.

[0080] The seal 324 is at least partially mounted on the elastic member 323, and preferably the seal 324 is mounted on the elastic member 323 and the two magnetic members 322. The provision of the seal 324 helps to ensure the sealing of the regulating assembly 32 when at least partially blocks the gas outlet, thereby preventing gas leakage and reducing the accuracy and efficiency of gas control.

[0081] Therefore, the regulating assembly 32 of this structural form can be used to achieve precise control of the gas supply, meet different combustion requirements, and ensure the reliability and stability of the movement of the regulating assembly 32 in the gas distribution pipe 200.

[0082] Furthermore, the height of the seal 324 along the moving direction X perpendicular to the adjusting component is not lower than the maximum height of the gas outlet end of the total gas pipeline 24. This structural form can effectively prevent leakage when the adjusting component 32 at least partially blocks the gas outlet, thereby improving the accuracy and efficiency of gas control.

[0083] Therefore, the regulating principle of the gas distribution device 100 in this embodiment is as follows:

[0084] When the electromagnetic coil 31 is not energized, the first magnetic member 3221 abuts against the limit block 21, the elastic member 323 is in a relaxed state and drives the sealing member 324 to at least partially cover the gas outlet end of the main gas pipeline 24. The at least partial overlap here depends on the elastic coefficient of the elastic member 323, which determines the range of the gas outlet end of the main gas pipeline 24 that it blocks.

[0085] When a positive current is passed through the electromagnetic coil 31, it can attract the second magnetic part 3222 to move toward one side of the first magnetic part 3221 along the extension direction of the fixed axis 321 until there is no overlapping area between the sealing part 324 and the gas outlet end of the main gas pipeline 24, that is, the gas outlet end of the main gas pipeline 24 is in a fully open state.

[0086] When a reverse current is passed through the electromagnetic coil 31, it can repel the second magnetic part 3222 and make the second magnetic part 3222 move along the extension direction of the fixed axis 321 toward the side away from the first magnetic part 3221 until the sealing part 324 completely covers the gas outlet end of the main gas pipeline 24, that is, the gas outlet end of the main gas pipeline 24 is in a completely blocked and closed state.

[0087] In this embodiment, by controlling the energization mode of the electromagnetic coil 31, the position of the adjustment component 32 can be precisely controlled to achieve control of gas distribution. In addition, by controlling the energization state of the electromagnetic coil 31, the gas supply can be quickly changed, and the gas supply amount can be flexibly adjusted to meet different combustion requirements.

[0088] Specifically, the electromagnetic coil 31 is arranged in the gas distribution pipe 200 near the adjustment component 32, so that Figure 2 and Figure 3 It can be seen that the electromagnetic coil 31 is arranged on one end of the first chamber 25 away from the adjustment space.

[0089] In this embodiment, since the electromagnetic coil 31 needs to influence and drive the position of the adjusting component 32, placing the electromagnetic coil 31 close to the adjusting component 32 can achieve more precise control of the adjusting component 32 by the electromagnetic coil 31. The adjusting component 32 can receive the electromagnetic force generated by the electromagnetic coil 31 more quickly and adjust the position of the adjusting component 32 relative to the gas outlet in time, thereby changing the gas supply.

[0090] Preferably, there are two limit blocks 21 , which are arranged on both sides of the gas inlet along the moving direction X of the adjustment assembly, and the distance between the two limit blocks 21 is not less than the maximum inner diameter of the gas inlet.

[0091] In this embodiment, this structural form can effectively limit the movement range of the adjustment component 32, ensuring that the adjustment component 32 can only move within a specified range, preventing excessive movement or exceeding the required range to cause failure in adjusting the gas outlet cross-sectional size.

[0092] In other embodiments, the limiting blocks 21 include three, which are respectively disposed in the first chamber 25 and located on the peripheral side wall surface of the gas distribution pipe 200 .

[0093] [Example 2]

[0094] Embodiment 2 discloses a gas water heater, which includes a combustion chamber box and the gas distribution device 100 of embodiment 1 for injecting gas into the combustion chamber box.

[0095] In this embodiment, the gas water heater adopts this structural form, and can realize automatic adjustment of the gas flow rate according to different seasons such as summer and winter, thereby adjusting the working range of the heating capacity of the gas water heater.

[0096] Therefore, the working principle of the gas water heater in this embodiment is as follows:

[0097] When the gas water heater has a large load demand, a positive current is passed through the electromagnetic coil 31, which can attract the second magnetic part 3222 to move along the extension direction of the fixed axis 321 toward the side of the first magnetic part 3221 until there is no overlapping area between the sealing part 324 and the gas outlet end of the main gas pipeline 24, that is, the gas outlet end of the main gas pipeline 24 is in a fully open state, which can reduce the load and ensure that the water temperature is cool enough for bathing in summer.

[0098] When the gas water heater has a small load demand, a reverse current is passed through the electromagnetic coil 31, which can repel the second magnetic part 3222 and make the second magnetic part 3222 move along the extension direction of the fixed axis 321 to the side away from the first magnetic part 3221 until the sealing part 324 completely covers the gas outlet end of the main gas pipeline 24, that is, the gas outlet end of the main gas pipeline 24 is in a completely blocked and closed state, which can increase the load and ensure that the water temperature is hot enough for bathing in winter.
