DETAILED DESCRIPTION

[0040] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] Please combine the specific Figures 1 to 12 As shown, the utility model discloses a gas system, comprising:

[0044] The valve body opening and closing part 1 has a pilot flame port and a functional port;

[0045] The electromagnetic valve body 2 is connected to the functional port of the valve body opening and closing member 1;

[0046] The burner component 6, in the long-fire state, the long-fire port of the valve body opening and closing component 1 is connected to the burner component 6. In the high-fire state, the solenoid valve body 2 will be opened so that the long-fire port and the functional port of the valve body opening and closing component 1 can both be connected to the burner component 6.

[0047] It should be noted that the fluid fuel used in the gas system is preferably gas, and the use of liquefied fuel or liquid fuel is a conventional replacement method in this field.

[0048] In this embodiment, please combine Figure 8 、 Figure 9 and Figure 10 As shown, the valve body opening and closing component 1 is preferably a plug valve body, and the valve body opening and closing component 1 is provided with a closing gear, a pilot flame gear, a functional gear and a valve body switch 13 for switching between the closing gear, the pilot flame gear and the functional gear. When the valve body switch 13 is switched to the pilot flame gear, the pilot flame port of the valve body opening and closing component 1 will be connected to the input port of the valve body opening and closing component 1 through the first internal flow channel 11, and when the valve body switch 13 is switched to the functional gear, both the pilot flame port and the functional port of the valve body opening and closing component 1 can be connected to the input port of the valve body opening and closing component 1, that is, the pilot flame port of the valve body opening and closing component 1 is connected to the input port of the valve body opening and closing component 1 through the first internal flow channel 11, and the functional port of the valve body opening and closing component 1 is connected to the input port of the valve body opening and closing component 1 through the second internal flow channel.

[0049] When the valve body switch 13 is switched to the closed position, the fluid fuel flows into the interior of the valve body opening and closing component 1 through the input port of the valve body opening and closing component 1, and will fill the first internal flow channel 11 and the second internal flow channel inside the valve body opening and closing component 1. The fluid fuel will be blocked by the valve body opening and closing component 1 and remain in the first internal flow channel 11 and the second internal flow channel inside the valve body opening and closing component 1, thereby achieving the purpose of cutting off the fluid fuel supply of the gas system to the burner component 6.

[0050] When the valve body switch 13 is switched to the long-fire position, the fluid fuel will be supplied to the burner component 6 through the long-fire port of the valve body opening and closing part 1. At this time, the burner component 6 is in a long-fire state and generates heat. Furthermore, a thermocouple 8 is also configured on the burner component 6, and an opening and closing solenoid valve electrically connected to the thermocouple 8 is preferably configured in the valve body opening and closing part 1. Usually, the thermocouple 8 is configured at the long-fire outlet end of the burner component 6. The thermocouple 8 is a sensor that connects one end of two metals of different materials and uses the thermoelectric effect to detect temperature. Among them, the metal end of the thermocouple 8 is connected to the solenoid valve body 2, and the heat generated by the burner component 6 will cause the thermocouple 8 on the burner component 6 to generate a high potential, forming an electric potential difference, causing the opening and closing solenoid valve in the valve body opening and closing part 1 to be attracted, thereby feedback that the burner component 6 and its gas system are in a normal use state, achieving the purpose of self-locking gas path.

[0051] In this way, the on-off solenoid valve in the valve body opening and closing member 1, in conjunction with the thermocouple 8, not only ensures the stability of the fluid fuel flow supply, but also, when the burner component 6 is not ignited and cannot generate heat to form a potential difference, the on-off solenoid valve in the valve body opening and closing member 1 cannot maintain the attracted state and resets to close. At this time, the fluid fuel cannot flow through the valve body opening and closing member 1, thus achieving the effect of timely cutting off the fluid fuel supply, thereby cooperating with the valve body switch 13 to achieve the purpose of dual protection.

[0052] When the valve body switch 13 is switched to the functional position, a portion of the fluid fuel will be supplied to the burner component 6 through the pilot flame port of the valve body opening and closing component 1, ensuring that the burner component 6 generates a pilot flame and heat, prompting the thermocouple 8 on the burner component 6 to generate a high potential, forming an electric potential difference, causing the opening and closing solenoid valve on the valve body opening and closing component 1 to be attracted, thereby providing feedback that the burner component 6 and its gas system are in normal use. The other portion of the fluid fuel will flow through the functional port of the valve body opening and closing component 1 to the solenoid valve body 2. After receiving the corresponding command, the solenoid valve body 2 opens, allowing the fluid fuel to flow through the solenoid valve body 2 and be supplied to the burner component 6. At this time, the amount of fluid fuel supplied to the burner component 6 is greatly increased, and the burner component 6 is in a high-fire state.

[0053] In this way, the free switching between the long-fire state and the high-fire state can be achieved by only using the cooperation of the burner component 6, the electromagnetic valve body 2 and the valve body opening and closing member 1, and the free switching between the heating and heat preservation of the gas system can be achieved. Compared with the gas circuit of the existing gas water heater, the independent switch provided on the main ventilation pipe and the branch pipe, as well as the long-fire burner and the burner assembly are saved, thereby achieving the purpose of greatly simplifying the number of parts and connections while maintaining the long-fire state and the high-fire state. At the same time, it also reduces the risk of leakage caused by loose connections or aging of pipe connections. In addition, it is also conducive to subsequent troubleshooting and maintenance, achieving the purpose of reducing production costs and subsequent maintenance costs.

[0054] As the preferred method of this embodiment, please refer to Figure 7 As shown, the gas system also includes a temperature control element 4, which is electrically connected to the solenoid valve body 2. The temperature control element 4 is used to detect the ambient temperature and can feedback control instructions to the solenoid valve body 2. Among them, the temperature control element 4 has a temperature monitoring circuit 42 for real-time monitoring of the ambient temperature. Preferably, the temperature monitoring circuit 42 uses an RC1 circuit composed of a thermistor and a capacitor and a detection element (such as a temperature probe). The actual temperature of the environment can be simulated by the change in the current. The change range of the RC1 circuit here is 0-100mA, and the temperature range detected by the temperature monitoring circuit 42 is -100℃-400℃. In this way, using the proportional formula, it can be seen that the temperature monitoring circuit 42 can infer a 1℃ change in the ambient temperature for every 0.2mA change.

[0055] It should be noted that the detection temperature range is preferably between 0℃-36℃. The detection temperature range is within the temperature range of 0℃-36℃, that is, controlling the ambient temperature within the temperature range of 0℃-36℃, which can effectively ensure that the human body feels more comfortable. When the ambient temperature exceeds 36℃, the human body will feel that the temperature is too high, which can easily cause fever and discomfort. When the ambient temperature is below 0℃, the ambient temperature is too low and can easily lead to the risk of frostbite. The detection temperature range is also preferably between 18℃-23℃, so as to ensure that the ambient temperature remains in the optimal temperature range of 18℃-23℃.

[0056] Further, please refer to Figure 7As shown, the temperature control element 4 also includes a wireless communication circuit 41. Here, the wireless communication circuit 41 is preferably a two-in-one Bluetooth and WiFi circuit. Of course, the wireless communication circuit 41 can also be a single Bluetooth circuit, or the wireless communication circuit 41 can also be a single Wi-Fi circuit. The thermocouple 8 is electrically connected to the wireless communication circuit 41, so that the thermocouple 8 can calculate the corresponding temperature value based on the potential difference and transmit the temperature value as first temperature information to the wireless communication circuit 41. The wireless communication circuit 41 uses a radio signal to feed back the first temperature information to the terminal device, which can then display the above temperature value in a timely manner.

[0057] In addition, the wireless communication circuit 41 is electrically connected to the temperature monitoring circuit 42, and simulates the actual temperature of the environment to form a second temperature signal and transmit it to the wireless communication circuit 41. The wireless communication circuit 41 uses a radio signal to feed back the second temperature information to the terminal device, and the terminal device can also display the actual temperature of the environment in a timely manner.

[0058] In this way, the terminal device will be able to simultaneously display the temperature value detected by the thermocouple 8 and the actual temperature of the environment, so that people can clearly understand the information of both, thereby facilitating timely response and adjustment of the gas system. Of course, the terminal device can also compare and analyze the temperature value detected by the thermocouple 8 with the actual temperature of the environment, thereby more efficiently converting it into a control instruction and sending it to the temperature control element 4, ultimately achieving the purpose of timely and efficient control of the opening or closing of the solenoid valve body 2, and achieving the purpose of real-time adjustment of the ambient temperature.

[0059] It should also be noted that the specific Figure 7 As shown, the wireless communication circuit 41 is also capable of receiving control commands sent by a terminal device. Specifically, the terminal device typically has a preset temperature parameter value. When the value of the second temperature signal received by the terminal device exceeds and / or falls below the temperature parameter value, the terminal device sends a corresponding control command to the wireless communication circuit 41 to control the operation of the solenoid valve body 2. The temperature parameter value can be any value within the temperature range of 0°C-36°C and can be freely adjusted according to user needs.

[0060] Of course, in addition to the above-mentioned comparison and analysis of the temperature parameter value and the second temperature signal, the temperature parameter value, the first temperature signal, and the second temperature signal can also be combined for a comprehensive analysis to improve the intelligence level of the gas system, thereby more comprehensively and effectively ensuring that the ambient temperature is within the optimal temperature range.

[0061] Further, please refer to Figure 7As shown, the temperature control element 4 further includes a control circuit 43 for electrically connecting to the solenoid valve body 2. The control circuit 43 can be adjusted or changed according to different types of solenoid valve bodies 2. Therefore, after receiving the control command, the wireless communication circuit 41 transmits it to the control circuit 43, which converts it into a control command compatible with the solenoid valve body 2, and finally transmits it to the solenoid valve body 2 to control the activation and deactivation of the solenoid valve body 2.

[0062] It should also be noted that the specific Figure 7 As shown, the temperature control element 4 also includes a power conversion circuit 44, which is used to convert household electricity into the power supply required by the wireless communication circuit 41. The household electricity is reduced in voltage by a capacitor, and then rectified, stabilized, and filtered to convert AC220V or AC110V into DC5V.

[0063] In some embodiments, please refer to Figure 7 As shown, the temperature control element 4 may further include a display module 45, preferably a display screen. The display module 45 is electrically connected to the wireless communication circuit 41. Both the first temperature information and the second temperature information can be transmitted to the display module 45 for synchronous display. Therefore, when a user leaves the terminal device, they can also observe the current temperature value detected by the thermocouple 8 and the actual ambient temperature through the display module 45 of the temperature control element 4. It should be noted that, depending on the design and requirements, the display module 45 may also display preset temperature parameter values.

[0064] Of course, the display module 45 can also be a control screen or a touch screen, so that people can temporarily debug and set parameters based on the temperature value detected by the currently displayed thermocouple 8 and the actual temperature of the environment when leaving the terminal device, thereby improving the convenience of people controlling the gas system.

[0065] In the above-mentioned gas system, not only can the free switching between the long-open flame state and the high-fire state be achieved by using fewer parts, which is beneficial to the free switching between the heating and insulation of the gas system, but it can also analyze the current ambient temperature and the temperature value detected by the thermocouple 8, and automatically switch the long-open flame state and the high-fire state of the gas system according to the current ambient temperature and the temperature value detected by the thermocouple 8, thereby ensuring that people are in a more suitable ambient temperature and effectively improving the comfort of the environment.

[0066] However, if a gas system is left running continuously or at high intensity for extended periods in a wide area, it consumes a significant amount of fluid fuel, resulting in significant waste. Furthermore, when people are confined to a single location within a wide area, the gas system cannot effectively and quickly heat that specific area.

[0067] In response to the above problems, the utility model author also discloses a further preferred solution. Figures 1 to 6 As shown, the gas system further includes a reversing valve body 3 , which is disposed between the burner component 6 and the valve body opening and closing member 1 , and is used to change the position of the gas flowing into the burner component 6 .

[0068] It should be noted that the reversing valve body 3 also belongs to the mature existing technology in this field. It is a directional control valve with more than two flow forms and more than two oil ports. It is a valve that realizes the communication, cutoff, reversing, pressure unloading, and sequential action control of fluid fuel. According to the number of working positions where the reversing valve core of the reversing valve body 3 stays in the reversing valve body, it is divided into a two-position reversing valve, a three-position reversing valve, etc. Alternatively, according to the number of oil circuits connected to the valve body, it is divided into a two-way reversing valve, a three-way reversing valve, a four-way reversing valve and a six-way reversing valve, etc. Alternatively, according to the way the reversing valve core moves, there are manual reversing valves, motorized reversing valves, electric reversing valves, hydraulic reversing valves, electro-hydraulic reversing valves and other types. The specific type and model of the reversing valve body 3 are not limited here. The specific model of the reversing valve body 3 can be selected according to actual demands and structural design.

[0069] Preferably, the reversing valve body 3 is disposed between the burner component 6 and the solenoid valve body 2. That is, when the solenoid valve body 2 is opened, the fluid fuel flows to the reversing valve body 3. Utilizing the reversing action of the reversing valve body 3, the flow direction of the fluid fuel can be timely changed, allowing the fluid fuel to enter from different positions of the burner component 6. This in turn changes the combustion and heating of the fluid fuel at different positions of the burner component 6, achieving the purpose of flexibly changing the heat generation position according to demand, thereby solving the problem that the gas system cannot effectively and quickly heat a localized location in the environment in a targeted manner.

[0070] For details, please refer to Figures 1 to 6 As shown, the reversing valve body 3 has a first main outlet, a second main outlet, a first auxiliary outlet, a second auxiliary outlet, a functional input port and a pilot light input port. The functional port of the valve body opening and closing component 1 is connected to the input port of the solenoid valve body 2 through a first pipe 51, the first main outlet and the second main outlet are both connected to the pilot light input port, the first auxiliary outlet and the second auxiliary outlet are both connected to the functional input port, the output port of the solenoid valve body 2 is connected to the functional input port of the reversing valve body 3 through a second pipe 52, and the pilot light port of the valve body opening and closing component 1 is connected to the pilot light input port of the reversing valve body 3 through a third pipe 53.

[0071] The burner component 6 has an NG main port 61, an LPG main port 62, an NG secondary port 63 corresponding to the NG main port 61, and an LPG secondary port 65 corresponding to the LPG main port 62. The term "relative" here should be understood as correspondingly conductive. That is, the area covered by the pilot flame outlet of the burner component 6 is defined as the pilot flame combustion zone. The pilot flame combustion zone is then divided into a first combustion zone and a second combustion zone based on the position of the flame. Both the NG main port 61 and the NG secondary port 63 can direct the supply of fluid fuel to the first combustion zone of the burner component 6, while both the LPG main port 62 and the LPG secondary port 65 can direct the supply of fluid fuel to the second combustion zone of the burner component 6.

[0072] Please refer to the following for details: Figures 1 to 6 As shown, the NG main port 61 is connected to the first main outlet of the reversing valve body 3 through the fourth pipe 54, the LPG main port 62 is connected to the second main outlet of the reversing valve body 3 through the fifth pipe 55, the NG sub-port 63 is connected to the first sub-outlet of the reversing valve body 3 through the sixth pipe 56, and the LPG sub-port 65 is connected to the second sub-outlet of the reversing valve body 3 through the seventh pipe 57.

[0073] Thus, when the reversing valve body 3 is switched to the NG control position, the fluid fuel entering the reversing valve body 3 is transported to the NG main port 61 of the burner component 6 under the guidance of the fourth pipe 54. The fluid fuel flows through the NG main port 61 and is supplied to the first combustion zone of the burner component 6. At this time, the first combustion zone of the burner component 6 is in the pilot state. When the reversing valve body 3 is switched to the LPG control position, the fluid fuel entering the reversing valve body 3 is transported to the LPG main port 62 of the burner component 6 under the guidance of the fifth pipe 55. The fluid fuel flows through the LPG main port 62 and is supplied to the second combustion zone of the burner component 6. At this time, the second combustion zone of the burner component 6 is in the pilot state.

[0074] When the valve body switch 13 of the valve body opening and closing member 1 is switched from the pilot flame position to the functional position, and the reversing valve body 3 is switched to the NG control position, the fluid fuel entering the reversing valve body 3 under the guidance of the third pipe 53 will be delivered to the fourth pipe 54, and then, under the guidance of the fourth pipe 54, delivered to the NG main port 61 of the burner component 6. Synchronously, another portion of the fluid fuel entering the reversing valve body 3 under the guidance of the second pipe 52 will be delivered to the sixth pipe 56, and then, under the guidance of the sixth pipe 56, delivered to the NG secondary port 63 of the burner component 6. The two portions of fluid fuel are combined and supplied to the first combustion zone of the burner component 6. At this time, the first combustion zone of the burner component 6 is in a high-fire state.

[0075] When the valve switch 13 of the valve body opening and closing member 1 is switched from the pilot position to the functional position, and the reversing valve body 3 is switched to the LPG control position, the fluid fuel entering the reversing valve body 3 under the guidance of the third pipe 53 will be delivered to the fifth pipe 55, and then, under the guidance of the fifth pipe 55, delivered to the LPG main port 62 of the burner component 6. Simultaneously, another portion of the fluid fuel entering the reversing valve body 3 under the guidance of the second pipe 52 will be delivered to the seventh pipe 57, and then, under the guidance of the seventh pipe 57, delivered to the LPG secondary port 65 of the burner component 6. The two portions of fluid fuel are combined and supplied to the second combustion zone of the burner component 6. At this time, the second combustion zone of the burner component 6 is in a high-fire state.

[0076] It can be seen that through the cooperation of the reversing valve body 3, the solenoid valve body 2 and the valve body opening and closing part 1, not only can the purpose of targeted long-lasting flame heating and heat supply be achieved at different locations in the environment, but also the effect of targeted high-fire rapid heating and temperature increase can be achieved at different locations in the environment, thereby greatly improving the freedom and accuracy of temperature control of the gas system.

[0077] It should be noted that the reversing valve body 3 is not limited to the two gears of NG control gear and LPG control gear. The corresponding reversing valve body 3 can be selected according to the type of burner component 6. For example, if the burner component 6 is equipped with three combustion zones, the reversing valve body 3 will have three corresponding adjustment gears.

[0078] In addition, in other embodiments, according to the experience of those skilled in the art, the reversing valve body 3 can also be arranged between the valve body opening and closing member 1 and the solenoid valve body 2, which can also achieve the above-mentioned effects of targeted long-fire heating and high-fire rapid heating of different locations in the environment.

[0079] As a further preferred embodiment of this embodiment, please refer to Figures 1 to 6 as well as Figures 8 to 10 As shown, the gas system also includes a pressure-stabilizing valve body 7, which is connected to the input port of the valve body opening and closing member 1 via an eighth conduit 58. Specifically, the pressure-stabilizing valve body 7 acts as a throttling element with variable local resistance. By varying the throttling area, the flow velocity and kinetic energy of the fluid are altered, resulting in varying pressure losses, thereby achieving the purpose of reducing pressure. By utilizing the pressure-reducing and regulating properties of the pressure-stabilizing valve body 7, the pressure of the fluid fuel flowing into the pressure-stabilizing valve body 7 is reduced to the pressure set by the pressure-stabilizing valve body 7 output, and is stably delivered to the input port of the valve body opening and closing member 1, thereby effectively improving the operational stability of the gas system.

[0080] Preferably, please combine Figure 11 and Figure 12As shown, the solenoid valve body 2 and the valve body opening and closing member are integrally formed. The integral forming here can be optionally detachable, such as a threaded connection, a clamping connection, etc. Welding connection or injection molding integral processing can also be selected, making the structure of the gas system more streamlined, requiring fewer pipes and pipe connectors for connection, thereby reducing the risk of leakage and the difficulty of troubleshooting, and at the same time, facilitating assembly and connection.

[0081] Based on the structure and connection relationship of the above-mentioned gas system, the inventors also disclose a heating device using the gas system, which includes the above-mentioned gas system. The heating device here is a gas heater, and can also be a gas cooker, a gas oven, a gas air conditioner, or a gas water heater.

[0082] In addition, based on the structure and connection relationship of the above-mentioned gas system, the utility model also discloses a temperature control method, which includes the following steps:

[0083] Step 1: Turn the valve body switch 13 of the valve body opening and closing member 1 to the pilot flame position to put the burner component 6 in the pilot flame state;

[0084] Step STEP 2: The valve body switch 13 of the valve body opening and closing member 1 is turned to the functional gear position. If the electromagnetic valve body 2 receives the control instruction and is in the open mode, the burner component 6 is in a high-fire state.

[0085] In this way, when the ambient temperature is relatively comfortable (i.e., when the terminal device compares the second temperature signal to be no higher than and / or no lower than the temperature parameter value), the solenoid valve body 2 will not receive the control command and will remain closed. At this time, when the valve body switch 13 of the valve body opening and closing member 1 is in the functional gear position, the burner component 6 will continue to operate in the steady flame state. When the ambient temperature is lower, a corresponding control command will be sent to the wireless communication circuit 41 of the temperature control element 4, thereby controlling the solenoid valve body 2 and causing the burner component 6 to switch to the high flame state.

[0086] Furthermore, in step STEP1, the following step STEP11 is also included:

[0087] Switch the reversing valve body 3 of the gas system from the NG control position to the LPG control position, or switch the reversing valve body 3 of the gas system from the LPG control position to the NG control position, so as to achieve the purpose of targeted long-lasting flame heating and heat supply to different locations in the environment.

[0088] Alternatively, in step STEP2, the following step STEP21 is further included:

[0089] Switch the reversing valve body 3 of the gas system from the NG control position to the LPG control position, or switch the reversing valve body 3 of the gas system from the LPG control position to the NG control position, so as to achieve the effect of targeted high-fire rapid heating and temperature increase at different locations in the environment.

[0090] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
