Description

Technical Field

[0001] This application relates to the technical field of gas stove testing devices, and in particular to a gas-fired indoor temperature control system. Background Technology

[0002] As a widely used combustion device in households and industries, the accuracy of testing core performance indicators such as combustion efficiency, heat load, and flue gas emissions of gas stoves directly affects product quality control, safe use, and energy efficiency rating. To ensure the authenticity, reliability, and comparability of test data, gas stove performance testing must be conducted in a standardized laboratory environment. Ambient temperature is one of the key external factors affecting test data and must be strictly controlled to eliminate interference. According to industry standards and experimental specifications for gas stove performance testing, to minimize the impact of external ambient temperature fluctuations on test results and improve testing accuracy, the indoor temperature must be stably controlled at around the standard value of 20℃ during laboratory testing to ensure the consistency of the testing environment.

[0003] Currently, the common practice in laboratories for testing gas stoves is to install several air conditioning units in the testing room to regulate the overall temperature of the room through the cooling and heating functions of the air conditioning system, thereby achieving a standard temperature control of 20°C. This temperature control method is simple to operate, low in cost, widely used in various laboratory environments, and can meet the temperature control needs of general scenarios, thus meeting the basic requirements for laboratory environmental control.

[0004] Regarding the aforementioned technologies, the inventors discovered that existing temperature control methods have significant technical defects when applied to laboratory performance testing of gas stoves, making it difficult to meet the requirements of high-precision testing. Specifically, when air conditioning equipment is operating, its air outlet generates a continuous airflow. When the air outlet rate of the air conditioner is high, the airflow will directly diffuse to the vicinity of the combustion area of ​​the gas stove, forming local airflow disturbances. The combustion process of the gas stove is extremely sensitive to the surrounding airflow environment. Such local airflow disturbances will disrupt the stable combustion conditions of the gas stove, causing flame flickering and incomplete combustion, thereby affecting the accuracy of the test data of core performance indicators such as heat load and combustion efficiency, resulting in deviations in test results and failing to truly reflect the actual performance of the gas stove. Summary of the Invention

[0005] To overcome the problem that existing air conditioning equipment generates continuous airflow at its outlet, and when the airflow rate is high, the airflow directly diffuses to the vicinity of the combustion area of ​​the gas stove, forming local airflow disturbances. The combustion process of the gas stove is extremely sensitive to the surrounding airflow environment. Such local airflow disturbances will disrupt the stable combustion conditions of the gas stove, causing flame flickering and incomplete combustion, which in turn affects the accuracy of the test data of core performance indicators such as heat load and combustion efficiency, resulting in deviations in test results and failing to truly reflect the actual performance of the gas stove, this application provides a gas indoor temperature control system.

[0006] The gas-fired indoor temperature control system provided in this application adopts the following technical solution:

[0007] A gas-fired indoor temperature control system includes a gas flow regulating component, a flow damper, a flow path regulating component, a diverter pipe, and an outlet box. The inlet end of the gas flow regulating component is connected to the outlet duct port of an air conditioning system, and the outlet end of the gas flow regulating component is connected to the flow damper, which is used to slow down the flow velocity of the guided airflow. The outlet end of the flow damper is connected to the flow path regulating component, and the outlet end of the flow path regulating component is connected to the diverter pipe, which is fixed to the ceiling inside the laboratory. The inlet end of the diverter pipe is connected to the regulating cylinder, and the other end of the regulating cylinder is connected to the outlet end of the flow path regulating component. Multiple branch pipes are connected to the diverter pipe, and multiple assembly screws are horizontally fixed to the lower outer wall of the multiple branch pipes. Multiple outlet boxes are provided, and the multiple outlet boxes are located below the diverter pipe and are evenly assembled on the ceiling inside the laboratory.

[0008] By adopting the above technical solution, and by setting up a gas flow regulation component, a flow damper, a flow path regulator, a diverter pipe, and an outlet box, this gas-fired indoor temperature control system effectively improves the gas delivery effect. Firstly, by setting up the gas flow regulation component, whose inlet end is connected to the outlet duct of the air conditioning system, it ensures that the airflow discharged from the air conditioning system can smoothly enter the system, achieving initial airflow stabilization. The flow damper, connected to the outlet end of the gas flow regulation component, reduces the flow velocity of the guided airflow, thus initially lowering the airflow speed. This allows for more even gas distribution in subsequent stages, avoiding waste and unevenness caused by excessively fast airflow. The flow path regulator further ensures smooth airflow and even distribution. The diverter pipe, connected to the outlet end of the flow path regulator, enhances the airflow adjustment capability, allowing the airflow to adapt more flexibly to different indoor environments. The system's key feature is its distribution pipes fixed to the laboratory ceiling, which consist of multiple branch pipes connected to and secured with various assembly screw housings. These branch pipes are connected to the outlet of the flow path regulator via an adjusting cylinder, enabling precise control of the airflow. This structural design helps ensure the uniformity and effectiveness of airflow distribution within the room, improving the system's stability and controllability. The addition of outlet boxes further enhances the system's functionality. Multiple outlet boxes, evenly integrated into the laboratory ceiling, provide more outlets, ensuring more even gas distribution throughout the room and further improving the system's diffusion effect and uniformity.

[0009] Optionally, the gas flow regulating assembly includes a regulating pipe and a gas supply tube. Multiple diverter tubes are horizontally and vertically connected and fixed on the upper side of the outer circumference of the regulating pipe, and the regulating pipe is horizontally fixed on the ceiling inside the laboratory. One end of the regulating pipe is open, and a gas supply tube is horizontally inserted into the opening of the regulating pipe. The outer end of the gas supply tube is connected and fixed to a gas supply pipe, and the other end of the gas supply pipe is connected and fixed to the air outlet duct port of the air conditioning system. The gas supply tube is located on the upper part of the inner side of the regulating pipe with an opening.

[0010] By adopting the above technical solution, a regulating pipe is horizontally fixed to the ceiling inside the laboratory, with one end open. A gas delivery tube can be slidably installed on the upper part of the inner side of the regulating pipe. Multiple diverter tubes are horizontally and vertically connected and fixed to the upper side of the outer circumference of the regulating pipe. This design allows the gas to be diverted as it passes through the regulating pipe, resulting in a more even distribution among the diverter tubes. Due to the presence of the diverter tubes, the gas is evenly distributed, making the airflow entering the laboratory more stable and controllable. A gas delivery pipe is fixedly connected to the outer end of the gas delivery tube, and the other end of the gas delivery pipe is fixedly installed at the outlet duct of the air conditioning system. The gas delivery tube can slide inside the regulating pipe. By adjusting the position of the gas delivery tube, the depth to which the gas delivery pipe is inserted into the regulating pipe can be changed, thereby changing the airflow through the gas delivery tube. This design allows engineers to flexibly adjust the airflow according to the actual needs of the laboratory, achieving precise airflow control and improving the regulation effect of the laboratory environment. Therefore, by adjusting the position of the gas delivery tube, the airflow entering the laboratory can be effectively regulated, thereby maintaining a good laboratory environment.

[0011] Optionally, pistons are fixed through the outer wall of the gas delivery tube on both sides of the opening, and a sealing post is fitted on the outer wall of the gas delivery tube. The sealing post is made of rubber and is used to seal multiple diverter cylinders on the regulating pipe. An regulating electric cylinder is fixed horizontally on the outside of the regulating pipe, and the output end of the regulating electric cylinder is fixed at the outer end of the gas delivery tube.

[0012] By adopting the above technical solution and designing the gas delivery cylinder and piston, with the piston positioned on the outer wall of the cylinder and fixed through both sides of its opening, the gas delivery cylinder can more effectively transmit gas. The gas delivery cylinder can be flexibly adjusted for gas transmission by regulating the electric cylinder's drive. Because the sealing column is made of rubber, it possesses excellent sealing and elasticity, tightly sealing the openings of multiple distribution cylinders on the regulating pipe, thereby achieving precise control of the gas flow rate. This design of the sealing column ensures that the gas achieves the required flow rate and pressure distribution under different operating conditions, which is crucial for achieving accurate and stable gas distribution.

[0013] Optionally, the flow-slowing component includes a guide tube and a flow-slowing cylinder. The guide tube is horizontally positioned above the gas flow regulating component, and multiple flow-slowing cylinders are horizontally and vertically connected and fixed at the bottom of the outer circumference of the guide tube. The diameter of the multiple flow-slowing cylinders increases horizontally in sequence, and the bottom ends of the multiple flow-slowing cylinders are connected and fixed to the ends of multiple flow-slowing cylinders of the regulating pipe. Multiple perforated plates are horizontally fixed in the vertical direction inside the multiple flow-slowing cylinders, and the guide tube is open at one end near the flow diameter regulating component.

[0014] By adopting the above technical solution, and through the technical features of the guide tube and the flow-retarding tube, the guide tube is horizontally positioned above the gas flow regulation component, ensuring that the gas can smoothly enter the guide tube from the gas flow regulation component. Since multiple flow-retarding tubes are horizontally and vertically connected and fixed from the bottom of the guide tube, with their diameters increasing sequentially, the gas gradually rises during flow, and the change in pipe diameter causes the gas velocity to gradually decrease, thus creating a flow-retarding effect. The multiple flow-retarding tubes, with their gradually increasing diameters, guide the gas velocity downwards, reducing the impact force of the gas flow, reducing eddies and turbulence, and making the gas more stable in a controlled environment. Simultaneously, multiple perforated plates are horizontally fixed vertically inside the flow-retarding tube, further refining the gas flow path, increasing gas uniformity, and improving the uniformity and stability of gas distribution.

[0015] Optionally, the flow path adjustment component includes an outer cylinder, an airbag ring cylinder, and a flexible cylinder. The outer cylinder is horizontally fixed to the ceiling inside the laboratory, and an airbag ring cylinder is horizontally inserted and fixed inside the outer cylinder. A flexible cylinder is horizontally inserted inside the airbag ring cylinder. Both ends of the flexible cylinder are open, and one end of the flexible cylinder is connected and fixed to the air outlet end of the guide tube. The other end of the flexible cylinder is horizontally rotatably connected to an assembly screw tube.

[0016] By adopting the above technical solution, a stable support is provided by horizontally fixing the outer cylinder to the laboratory ceiling, ensuring the horizontal installation and normal operation of the airbag annulus and flexible cylinder. The airbag annulus can expand and contract within a certain range as needed, giving the flexible cylinder inside sufficient space to expand or contract, thereby regulating the gas flow rate and velocity. The open design at both ends of the flexible cylinder allows airflow to flow freely within it. Simultaneously, one end of the flexible cylinder is connected and fixed to the outlet end of the guide tube, while the other end is rotatably connected to the assembly solenoid. This not only ensures the continuity of airflow but also enhances the flexibility of airflow direction, allowing the gas to flow in a directional manner according to experimental requirements. This structure of the flexible cylinder brings multiple technical benefits. First, the fixing effect of the outer cylinder ensures the stability of the entire device; second, the combination of the airbag annulus and flexible cylinder achieves throttling and buffering of the airflow, effectively controlling the gas flow rate and velocity, and improving the precision of gas regulation.

[0017] Optionally, an air inlet pipe is fixedly connected to the outer cylinder through the airbag ring, and a valve is assembled on the air inlet pipe, with an air pump fixedly connected to the end of the air inlet pipe.

[0018] By adopting the above technical solution, an air inlet pipe is fixedly connected to the outer cylinder of the airbag ring. This air inlet pipe, through a valve, forms a controllable passage to the external environment, thus enabling the inflation and deflation of the airbag. Specifically, an air pump supplies gas to the inside of the airbag ring through the air inlet pipe. When the gas in the airbag ring is supported by the outer cylinder, a certain pressure distribution is formed, providing support and stability, thereby achieving the effect of regulating the stability of the machine or equipment. Furthermore, because a valve is installed on the air inlet pipe, the inflation and deflation process of the airbag can be effectively controlled, further realizing the function of dynamically adjusting to demand, that is, adjusting the stability according to real-time needs.

[0019] Optionally, an adjusting cylinder is fixedly connected to the air inlet end of the splitter pipe. An assembly screw is fixedly connected horizontally to the end of the adjusting cylinder away from the splitter pipe. The assembly screw is threadedly connected to the assembly screw tube at the end of the flexible cylinder. Two guide plates are symmetrically and vertically fixed inside the adjusting cylinder. Multiple through slots are opened through the two guide plates. An adjusting plate is vertically arranged inside the adjusting cylinder between the two guide plates. Sealing bearings are fixed on both sides of the outer wall of the adjusting plate. The outer rings of the sealing bearings on both sides of the adjusting plate are fixed to the inner wall of the adjusting cylinder. Multiple through slots are opened through the adjusting plate.

[0020] By adopting the above technical solution, and by setting up a diverter pipe and its regulating cylinder, the guide orifice plate and regulating orifice plate inside the regulating cylinder can jointly regulate the gas flow path and flow rate. Multiple slots on the guide orifice plate can guide the gas to be evenly distributed inside the regulating cylinder, ensuring a more uniform gas distribution. The regulating orifice plate inside the regulating cylinder can be screwed in or out as needed to change its distance from the guide orifice plate. The adjustment process of the regulating orifice plate mainly involves adjusting its distance from the guide orifice plate, thereby changing the airflow area through the orifice, thus achieving precise control of the gas flow rate. This adjustment method is flexible and adaptable, and can quickly respond to flow requirements under different operating conditions; this is achieved through changes in the relative position between the regulating orifice plate and the guide orifice plate.

[0021] Optionally, an adjusting motor is horizontally fixed on the outer wall of the adjusting cylinder, and an adjusting gear is fixed at the output end of the adjusting motor. A gear ring is fixed on the outer wall of the adjusting orifice plate, penetrating the outer wall of the adjusting cylinder, and the gear ring meshes with the adjusting gear.

[0022] By adopting the above technical solution, the rotation of the adjusting gear can be precisely controlled by adjusting the speed and rotational speed of the output end of the adjusting motor. The adjusting gear meshes with the gear ring fixed on the outer wall of the adjusting orifice plate, forming a meshing transmission system. Due to the meshing of the gear ring and the adjusting gear, when the adjusting motor rotates, it can precisely drive the adjusting orifice plate to rotate by a corresponding angle, thereby adjusting the opening degree of the orifice plate at a fixed position.

[0023] Optionally, multiple assembly slots are provided on one symmetrical vertical end face of the vent box, and multiple assembly clips are fixed on the other symmetrical vertical end face of the vent box. The multiple assembly clips adjacent to the vent box are connected to the multiple assembly slots for assembly. Multiple vent holes are provided through the bottom surface of the vent box, and a screw is vertically fixed on the bottom surface inside the vent box. A screw frame is assembled on the screw with vertical threads, and the top of the screw frame is fixed to the ceiling inside the laboratory by bolts. A sliding frame is horizontally fixed on one vertical end face inside the vent box.

[0024] By adopting the above technical solution, and by setting up assembly slots and clips for the venting frame, the assembly slots and clips enable rapid assembly and installation of the venting frame. Since standard-sized assembly slots and clips are used, no tools are required; installation is completed simply by aligning the slots and clips, thus facilitating installation and disassembly. Multiple vent holes running through the bottom of the venting frame allow gas to be discharged evenly and smoothly from the bottom. Because the gas is distributed through multiple vent holes, the direction and distribution of gas discharge are more uniform, avoiding localized pressure changes caused by concentrated airflow. Therefore, it achieves uniform ventilation, improves the laboratory ventilation environment, and enhances the accuracy of experiments. The screws and screw frames on the bottom surface of the vent box are fixed to the ceiling inside the laboratory by bolts, so that the vent box can be stably installed on the top of the laboratory, avoiding accidental movement caused by external forces. Due to the cooperation of the screws and screw frames, the installation of the vent box is more stable and not easily affected by accidental impacts, thus playing the role of fixing the structure.

[0025] Optionally, a cartridge air box is horizontally inserted on the cartridge slide frame, and a connecting bellows is vertically connected and fixed to the top of the cartridge air box. A threaded joint is vertically connected and rotatably connected to the top of the connecting bellows, and the threaded joint on the connecting bellows is threadedly connected and assembled with the assembly screw shell. Multiple diversion tubes are vertically connected and fixed on the cartridge air box.

[0026] By adopting the above technical solution, and by setting the technical feature of horizontally inserting a cartridge gas box on the cartridge slide frame, the cartridge gas box can be easily fixed on the cartridge slide frame, ensuring the stability and maintainability of the equipment. Since the top of the cartridge gas box is vertically connected and fixed with a connecting bellows, the elasticity of the connecting bellows ensures smooth gas flow, effectively adapting to pressure changes during use and preventing equipment failures caused by pressure fluctuations. By vertically connecting and rotating a threaded joint at the top of the connecting bellows, this design makes the gas pipeline connection more flexible, facilitating system assembly and maintenance, while ensuring the sealing and stability of the connection. Furthermore, the threaded joint on the connecting bellows is threadedly connected to the assembly housing, making the gas pipeline connection more reliable and ensuring the system's sealing and safety. Multiple distribution orifices are vertically connected and fixed on the cartridge gas box. The design of these distribution orifices allows for uniform gas distribution, avoiding excessive local pressure, thereby improving the uniformity and efficiency of gas distribution.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] This gas-fired indoor temperature control system addresses the core pain points of the prior art—namely, the disturbance of airflow in the combustion zone of the gas stove and the distortion of test data caused by direct temperature control by air conditioning—through a collaborative design of airflow diversion and regulation, flow rate reduction, flow path adaptation, and uniform air distribution. It achieves stable indoor temperature control in the laboratory at around the standard value of 20℃, while eliminating local airflow disturbances, ensuring stable combustion conditions of the gas stove, and guaranteeing the accuracy and reliability of test data. This system is well-suited to the temperature control requirements of high-precision performance testing of gas stoves in laboratories.

[0029] In summary, this system's gas flow regulation components achieve airflow introduction and diversion control; the flow damper decelerates the airflow, eliminating the potential hazards of high-speed airflow; the flow path regulator ensures precise matching of airflow path and velocity; the diversion pipe ensures uniform airflow distribution and conduction; and the outlet box ensures uniform air distribution throughout the entire area. The entire system is rationally designed and easy to control, solving the airflow disturbance problem caused by existing air conditioning temperature control, ensuring stable temperature and smooth airflow in the gas stove laboratory testing environment, guaranteeing the accuracy of test data, and adapting to high-precision testing requirements.

Detailed Implementation

[0039] The present application will be further described in detail below with reference to the accompanying drawings.

[0040] This application discloses a gas-fired indoor temperature control system. The system includes a gas flow regulating component 1, a flow damper 2, a flow path regulating component 3, a diverter pipe 4, and an outlet box 5. The inlet end of the gas flow regulating component 1 is connected to the outlet duct port of an air conditioning system, and the outlet end of the gas flow regulating component 1 is connected to the flow damper 2, which slows down the flow velocity of the guided airflow. The outlet end of the flow damper 2 is connected to the flow path regulating component 3, and the outlet end of the flow path regulating component 3 is connected to the diverter pipe 4, which diverts the airflow... Pipe 4 is fixed to the ceiling inside the laboratory. The air inlet end of the diversion pipe 4 is connected to an adjusting cylinder 42, and the other end of the adjusting cylinder 42 is connected to the air outlet end of the flow path adjusting component 3. Multiple branch pipes are connected to the diversion pipe 4, and multiple assembly screw shells 41 are horizontally connected and fixed below the outer wall of the multiple branch pipes of the diversion pipe 4. Multiple air outlet boxes 5 are provided, and multiple air outlet boxes 5 are located below the diversion pipe 4, and multiple air outlet boxes 5 are evenly assembled on the ceiling inside the laboratory.

[0041] By adopting the above technical solution, and by setting up a gas flow regulating component 1, a flow modulator 2, a flow path regulating component 3, a diverter pipe 4, and an outlet box 5, this gas-fired indoor temperature control system effectively improves the gas delivery effect. Firstly, by setting up the gas flow regulating component 1, whose inlet end is connected to the outlet duct of the air conditioning system, it ensures that the airflow discharged from the air conditioning system can smoothly enter the system, achieving initial airflow stabilization. The flow modulator 2, connected to the outlet end of the gas flow regulating component 1, reduces the flow velocity of the guided airflow, thus initially lowering the airflow speed. This allows for more even gas distribution in subsequent stages, avoiding waste and unevenness caused by excessively fast airflow. The flow path regulating component 3 further ensures smooth airflow and even distribution. The diverter pipe 4, connected to the outlet end of the flow path regulating component 3, enhances the airflow adjustment capability, allowing the airflow to adapt more flexibly to different indoor environments. The system is characterized by a diversion pipe 4 fixed to the ceiling inside the laboratory, which has multiple branch pipes connected to and fixed with multiple assembly screw housings 41. These are connected to the outlet end of the flow path regulating component 3 via an adjusting cylinder 42, enabling precise control of the airflow. This series of structural designs helps ensure the uniformity and effectiveness of airflow distribution within the room, improving the system's stability and controllability. The addition of outlet boxes 5 further enhances the system's functionality. Multiple outlet boxes 5, evenly assembled on the laboratory ceiling, provide more outlets, ensuring that gas can be more evenly distributed to all corners of the room, further improving the system's diffusion effect and uniformity.

[0042] Reference Figure 4 and Figure 5The gas flow regulating assembly 1 includes a regulating pipe 11 and a gas delivery insert 14. Multiple distribution cylinders 12 are horizontally and vertically connected and fixed to the upper side of the outer circumference of the regulating pipe 11. The regulating pipe 11 is horizontally fixed to the ceiling inside the laboratory. One end of the regulating pipe 11 is open, and the gas delivery insert 14 is horizontally inserted into the opening. The outer end of the gas delivery insert 14 is connected and fixed to a gas delivery pipe 16, and the other end of the gas delivery pipe 16 is connected and fixed to the air outlet duct of the air conditioning system. The gas delivery insert 14 is located on the upper part of the inner side of the regulating pipe 11 with an opening. By setting the regulating pipe 11 horizontally fixed to the ceiling inside the laboratory with one end open, the gas delivery insert 14 can slide open on the upper part of the inner side of the regulating pipe 11. The design of horizontally and vertically connecting and fixing multiple distribution cylinders 12 to the upper side of the outer circumference of the regulating pipe 11 allows the gas to be diverted when passing through the regulating pipe 11, thus distributing it more evenly among the distribution cylinders 12. Due to the presence of the distribution tube 12, the gas is evenly distributed, making the airflow entering the laboratory more stable and controllable. The outer end of the gas delivery tube 14 is connected to and fixedly attached to a gas delivery pipe 16, the other end of which is connected to and fixedly attached to the outlet duct of the air conditioning system. The gas delivery tube 14 can slide inside the regulating pipe 11. By adjusting the position of the gas delivery tube 14, the depth to which the gas delivery pipe 16 is inserted into the regulating pipe 11 can be changed, thereby altering the airflow through the gas delivery tube 14. This design allows engineers to flexibly adjust the airflow according to the actual needs of the laboratory, achieving precise airflow control and improving the environmental regulation effect of the laboratory. Therefore, by adjusting the position of the gas delivery tube 14, the airflow entering the laboratory can be effectively regulated, thus maintaining a good laboratory environment. A piston 141 is fixedly installed through both sides of the opening on the outer wall of the gas delivery tube 14. A sealing post 15, made of rubber, is fitted onto the outer wall of the gas delivery tube 14 to seal the multiple diverter cylinders 12 on the regulating pipe 11. A regulating electric cylinder 13 is horizontally fixed to the outside of the regulating pipe 11, and its output end is fixed to the outer end of the gas delivery tube 14. By configuring the gas delivery tube 14 and piston 141, with the piston 141 located on the outer wall of the gas delivery tube 14 and fixed through both sides of its opening, the gas delivery tube 14 can more effectively transmit gas. The gas delivery tube 14 can flexibly adjust the gas transmission by being driven by the regulating electric cylinder 13. Because the sealing post 15 is made of rubber, it has good sealing properties and elasticity, and can tightly seal the openings of the multiple diverter cylinders 12 on the regulating pipe 11, thereby achieving precise control of the gas flow rate. This design of the sealing column 15 ensures that the gas can achieve the required flow and pressure distribution under different operating conditions, which is crucial for achieving accurate and stable gas distribution.

[0043] Reference Figure 4The flow-slowing component 2 includes a guide tube 21 and flow-slowing tubes 22. The guide tube 21 is horizontally positioned above the gas flow regulating component 1, and multiple flow-slowing tubes 22 are horizontally and vertically connected and fixed to the bottom of the outer circumference of the guide tube 21. The diameter of the multiple flow-slowing tubes 22 increases sequentially horizontally, and the bottom ends of the multiple flow-slowing tubes 22 are connected and fixed to the ends of multiple diverter tubes 12 of the regulating pipe 11. Multiple perforated plates 221 are horizontally fixed vertically inside the multiple flow-slowing tubes 22. The guide tube 21 is open at one end near the flow diameter regulating component 3. By setting the guide tube 21 and flow-slowing tubes 22, the guide tube 21 is horizontally positioned above the gas flow regulating component 1, ensuring that gas can smoothly enter the guide tube 21 from the gas flow regulating component 1. Since the multiple flow-slowing tubes 22 are horizontally and vertically connected and fixed from the bottom of the guide tube 21, and the diameter increases sequentially, the gas gradually rises during the flow process, and the change in pipe diameter causes the gas velocity to gradually decrease, thus creating a flow-slowing effect. Multiple progressively larger flow-retarding tubes 22 gradually guide the gas flow velocity downward by increasing the tube diameter. This reduces the impact force of the gas flow, reduces eddies and turbulence, and makes the gas more stable in a controlled environment. At the same time, multiple perforated plates 221 are fixed horizontally in the vertical direction inside the flow-retarding tubes 22, further refining the gas flow path, increasing the uniformity of the gas, and improving the uniformity and stability of the gas distribution.

[0044] Reference Figure 6The flow path regulating component 3 includes an outer cylinder 31, an airbag ring cylinder 32, and a flexible cylinder 33. The outer cylinder 31 is horizontally fixed to the ceiling inside the laboratory, and the airbag ring cylinder 32 is horizontally inserted and fixed inside the outer cylinder 31. The flexible cylinder 33 is horizontally inserted inside the airbag ring cylinder 32. Both ends of the flexible cylinder 33 are open, and one end of the flexible cylinder 33 is connected and fixed to the air outlet end of the guide tube 21. The other end of the flexible cylinder 33 is horizontally rotatably connected to an assembly screw tube 331. By setting the outer cylinder 31 horizontally fixed to the ceiling of the laboratory, a stable support is provided, ensuring the horizontal installation and normal operation of the airbag ring cylinder 32 and the flexible cylinder 33. The airbag ring cylinder 32 can expand and contract within a certain range as needed, which gives the flexible cylinder 33 inside the airbag ring cylinder 32 sufficient space to expand or contract, thereby regulating the flow rate and velocity of the gas. The open-end design of the flexible cylinder 33 allows airflow to flow freely within it. One end of the flexible cylinder 33 is fixedly connected to the outlet of the guide tube 21, while the other end is rotatably connected to the assembly solenoid 331. This not only ensures the continuity of airflow but also enhances the flexibility of airflow direction, allowing the gas to flow in a directional manner according to experimental requirements. This structure of the flexible cylinder 33 brings multiple technical benefits. First, the fixation of the outer cylinder 31 ensures the stability of the entire device. Second, the combination of the airbag ring cylinder 32 and the flexible cylinder 33 achieves throttling and buffering of the airflow, effectively controlling the gas flow rate and velocity, and improving the precision of gas regulation. An air inlet pipe 34 is fixedly connected to and passes through the outer cylinder 31 on the airbag ring cylinder 32, and a valve 341 is assembled and connected to the air inlet pipe 34. An air pump 35 is fixedly connected to the end of the air inlet pipe 34. An air inlet pipe 34 is fixedly connected to the outer cylinder 31 through the airbag ring cylinder 32. The air inlet pipe 34 forms a controllable passage with the external environment through a valve 341, thus enabling the inflation and deflation of the airbag. Specifically, the air pump 35 supplies gas to the inside of the airbag ring cylinder 32 through the air inlet pipe 34. When the gas in the airbag ring cylinder 32 forms a certain pressure distribution under the support of the outer cylinder 31, it plays a supporting and stabilizing role, thereby achieving the effect of adjusting the stability of the machine or equipment. In addition, since the valve 341 is installed on the air inlet pipe 34, the inflation and deflation process of the airbag can be effectively controlled, further realizing the function of dynamic adjustment according to demand, that is, adjusting the stability according to real-time needs.

[0045] Reference Figure 7An adjusting cylinder 42 is fixedly connected to the inlet end of the diverter pipe 4. An assembly screw 421 is horizontally fixed to the end of the adjusting cylinder 42 away from the diverter pipe 4, and the assembly screw 421 is threadedly connected to the assembly screw tube 331 at the end of the flexible cylinder 33. Two guide plates 422 are symmetrically and vertically fixed inside the adjusting cylinder 42, and multiple through slots are formed on the two guide plates 422. An adjusting plate 423 is vertically arranged inside the adjusting cylinder 42 between the two guide plates 422, and sealing bearings are fixed to both sides of the outer wall of the adjusting plate 423. The outer rings of the sealing bearings on both sides of the adjusting plate 423 are fixed to the inner wall of the adjusting cylinder 42. Multiple through slots are formed on the adjusting plate 423. By setting up the diverter pipe 4 and its adjusting cylinder 42, the guide plates 422 and the adjusting plate 423 inside the adjusting cylinder 42 can jointly regulate the flow path and flow rate of the gas. Multiple slots on the orifice plate 422 guide gas to distribute evenly within the regulating cylinder 42, ensuring a more uniform gas distribution. The regulating orifice plate 423 within the regulating cylinder 42 can be screwed in or out as needed to change its distance from the orifice plate 422. The adjustment process of the regulating orifice plate 423 primarily involves adjusting its distance from the orifice plate 422, thereby changing the airflow area through the orifice and achieving precise control of the gas flow rate. This adjustment method is flexible and adaptable, allowing for rapid response to flow demands under different operating conditions. This is achieved through changes in the relative position of the regulating orifice plate 423 and the orifice plate 422.

[0046] Reference Figure 7 An adjusting motor 424 is horizontally fixed to the outer wall of the adjusting cylinder 42, and an adjusting gear 425 is fixed to the output end of the adjusting motor 424. A gear ring 426 is fixed to the outer wall of the adjusting orifice plate 423, penetrating the outer wall of the adjusting cylinder 42, and the gear ring 426 meshes with the adjusting gear 425. By setting the adjusting motor 424, the rotation of the adjusting gear 425 can be precisely controlled by adjusting the speed and rotational speed of the output end. The adjusting gear 425 meshes with the gear ring 426 fixed to the outer wall of the adjusting orifice plate 423, forming a meshing transmission system. Due to the meshing of the gear ring 426 and the adjusting gear 425, when the adjusting motor 424 rotates, it can precisely drive the adjusting orifice plate 423 to rotate by a corresponding angle, thereby adjusting the opening of the orifice plate 423 at a fixed position.

[0047] Reference Figure 8Multiple assembly slots 52 are provided on one side of the vent frame box 5, and multiple assembly clips 53 are fixed on the other side of the vent frame box 5. The multiple assembly clips 53 adjacent to each other are connected to the multiple assembly slots 52 for assembly. Multiple vent holes are provided through the bottom surface of the vent frame box 5. A screw 54 is vertically fixed on the bottom surface inside the vent frame box 5, and a screw frame 55 is vertically threaded on the screw 54. The top of the screw frame 55 is fixed to the ceiling inside the laboratory by bolts. A sliding frame 51 is horizontally fixed on one side of the vent frame box 5. By setting up the assembly slots 52 and assembly clips 53 of the exhaust frame 5, the assembly slots 52 and assembly clips 53 can achieve rapid assembly and installation of the exhaust frame 5. Since the assembly slots 52 and clips 53 are of standard size, no tools are required; installation can be completed simply by aligning the slots 52 and clips 53, thus facilitating installation and disassembly. Multiple exhaust holes are opened through the bottom surface of the exhaust frame 5, allowing gas to be discharged evenly and smoothly from the bottom of the exhaust frame 5. Because the gas is distributed through multiple exhaust holes, the direction and distribution of gas discharge are more uniform, avoiding local pressure changes caused by concentrated airflow. Therefore, it achieves uniform exhaust, thereby improving the ventilation environment of the laboratory and enhancing the accuracy of experiments. The screw 54 and screw frame 55 on the bottom surface of the gas outlet box 5 are bolted to the ceiling inside the laboratory, thus ensuring the gas outlet box 5 is stably installed on the top of the laboratory and preventing accidental movement due to external forces. The cooperation of the screw and screw frame makes the installation of the gas outlet box 5 more stable and less susceptible to accidental impacts, thus serving as a structural fixation. A cartridge gas box 56 is horizontally inserted into the cartridge slide frame 51, and a connecting bellows 57 is vertically connected and fixed to the top of the cartridge gas box 56. A threaded connector is rotatably connected to the top of the connecting bellows 57, and the threaded connector on the connecting bellows 57 is threadedly connected and assembled with the assembly screw housing 41. Multiple diversion orifice cylinders 58 are vertically connected and fixed to the cartridge gas box 56. By setting the technical feature of horizontally inserting the cartridge gas box 56 onto the cartridge slide frame 51, the cartridge gas box 56 can be easily fixed onto the cartridge slide frame 51, ensuring the stability and maintainability of the equipment. Because the top of the cartridge gas box 56 is vertically connected to a connecting bellows 57, the elasticity of the bellows 57 ensures smooth gas flow, effectively adapting to pressure changes during use and preventing equipment failure due to pressure fluctuations. By vertically connecting the top of the bellows 57 to a threaded connector, this design makes the gas pipeline connection more flexible, facilitating system assembly and maintenance while ensuring the sealing and stability of the connection. Furthermore, the threaded connector on the bellows 57 is threadedly connected to the assembly housing 41, making the gas pipeline connection more reliable and ensuring the system's sealing and safety.Multiple flow divider cylinders 58 are vertically connected and fixed on the cartridge gas box 56. The design of these flow divider cylinders 58 enables the gas to be evenly distributed, avoiding excessive local pressure, thereby improving the uniformity and efficiency of gas distribution.

[0048] The implementation principle of a gas-fired indoor temperature control system according to an embodiment of this application is as follows:

[0049] The system uses the gas flow regulation component 1 as the basis for airflow introduction and diversion regulation, the flow buffer component 2 as the core of flow velocity buffering, the flow path adjustment component 3 as the component for precise matching of airflow path and flow velocity, the diversion pipe 4 as the airflow diversion and conduction carrier, and the gas outlet box 5 as the component for uniform air distribution execution. All components are connected in sequence and cooperate to form a complete temperature control airflow conduction link, which includes air conditioning air outlet, diversion regulation, flow velocity reduction, flow path matching, diversion conduction, and uniform air distribution. This not only achieves stable indoor temperature control but also avoids airflow disturbance from affecting gas stove testing.

[0050] The core of the airflow regulating component 1 is to control the introduction and diversion of air from the air conditioner, adapting to the airflow supply regulation under different temperature control requirements: its air inlet end is connected to the air outlet duct port of the air conditioning system through the air supply pipe 16, introducing the 20℃ standard temperature airflow generated by the air conditioner into the system. The airflow regulating component 1 includes a regulating pipe 11 and an air supply inlet 14. The regulating pipe 11 is horizontally fixed on the laboratory ceiling, and multiple diversion cylinders 12 are fixedly connected to its outer circumference for initial airflow diversion; the air supply inlet 14 is horizontally inserted at the opening of the regulating pipe 11, and its outer end is fixed to the air supply pipe 16. The air supply inlet 14 is located inside the regulating pipe 11 with an opening on one side, for introducing the air conditioning airflow into the regulating pipe 11.

[0051] On the outer wall of the gas delivery tube 14, pistons 141 are fixed through both sides of the opening to ensure sealing performance after insertion. Rubber sealing posts 15 are used to seal multiple diverter tubes 12 on the regulating tube 11. An regulating electric cylinder 13 is fixed on the outside of the regulating tube 11, with its output end fixed to the outer end of the gas delivery tube 14. It can drive the gas delivery tube 14 to slide horizontally along the regulating tube 11, thereby adjusting the opening position of the gas delivery tube 14 in the regulating tube 11, realizing the adjustment of the number and degree of opening of the diverter tubes 12. When it is necessary to increase the airflow supply, the regulating electric cylinder 13 drives the gas delivery tube 14 to slide, so that the sealing posts 15 can release the blockage of more diverter tubes 12, increasing the airflow diversion path. When it is necessary to reduce the airflow supply, the gas delivery tube 14 is adjusted in the opposite direction to reduce the number of opening diverter tubes 12, realizing precise control of the airflow supply and adapting to the temperature control needs of different areas of the laboratory.

[0052] The core function of the flow-slowing component 2 is to slow down the airflow velocity of the air conditioner and eliminate the disturbance of high-speed airflow to the combustion area of ​​the gas stove. It includes a guide tube 21 and a flow-slowing tube 22: the guide tube 21 is horizontally set above the gas flow regulating component 1, and its bottom is connected to multiple fixed flow-slowing tubes 22. The bottom ends are connected to the ends of multiple diverter tubes 12 fixed to the regulating pipe 11 to receive the diverted airflow. The diameter of the multiple flow-slowing tubes 22 increases horizontally. Combined with the multiple perforated plates 221 fixed vertically inside, the airflow can be slowed down step by step. After the airflow enters the flow-slowing tube 22 from the diverter tube 12, the flow velocity naturally decreases as the pipe diameter increases. After being blocked and diverted by the multiple perforated plates 221, the flow velocity is further slowed down, preventing high-speed airflow from directly entering the subsequent components and eliminating the potential for airflow disturbance from the source. The slowed airflow is collected in the guide tube 21 and introduced into the flow path regulating component 3 through the open end of the guide tube 21.

[0053] The flow path adjustment component 3 is used to further adapt the airflow velocity and flow path to ensure smooth airflow conduction. It includes an outer cylinder 31, an airbag ring cylinder 32, and a flexible cylinder 33: the outer cylinder 31 is horizontally fixed on the laboratory ceiling, and the airbag ring cylinder 32 is inserted and fixed inside to adjust the flow path of the flexible cylinder 33; the flexible cylinder 33 is horizontally inserted inside the airbag ring cylinder 32, with open ends. One end is connected and fixed to the air outlet end of the guide tube 21, and the other end is connected to the adjustment cylinder 42 of the diverter pipe 4 through the assembly solenoid 331 to conduct the slow-flowing airflow.

[0054] An air inlet pipe 34, which is fixed and passes through the outer cylinder 31, is connected to the airbag ring cylinder 32. It is connected to the air pump 35 through the valve 341. The air pump 35 can inflate or deflate the airbag ring cylinder 32. When it is necessary to reduce the airflow rate, the air pump 35 inflates the airbag ring cylinder 32, which expands and squeezes the soft cylinder 33, reducing the flow diameter of the soft cylinder 33 and further slowing down the airflow rate. When it is necessary to increase the airflow rate, the air is deflated through the valve 341, the airbag ring cylinder 32 contracts, the flow diameter of the soft cylinder 33 recovers, and the airflow rate increases. This achieves precise fine-tuning of the airflow rate and adapts to the stable airflow requirements under different temperature control scenarios.

[0055] The diverter 4 is used to evenly distribute the slowed and regulated airflow to each outlet box 5. It is fixed on the laboratory ceiling. The air inlet end is connected to the flexible tube 33 of the flow path adjustment component 3 through the regulating cylinder 42. The assembly screw 421 fixed at the end of the regulating cylinder 42 away from the diverter 4 is threadedly assembled with the assembly screw 331 at the end of the flexible tube 33 to achieve a detachable connection, which is convenient for installation and maintenance. Two guide orifice plates 422 are symmetrically fixed inside the regulating cylinder 42. Multiple through slots are opened in the plates to perform preliminary diversion and stabilization of the airflow, and to prevent the airflow from generating eddies in the regulating cylinder 42. The regulating orifice plate 423 is set between the two guide orifice plates 422. The sealing bearings on both sides of its outer wall are fixed to the inner wall of the regulating cylinder 42 to ensure the sealing when rotating. The through slots on the regulating orifice plate 423 can correspond to or be offset from the through slots of the guide orifice plate 422 to achieve the adjustment of the airflow.

[0056] An adjusting motor 424 fixed to the outer wall of the adjusting cylinder 42 has an adjusting gear 425 fixed to its output end, which meshes with a gear ring 426 fixed to the outer wall of the adjusting orifice plate 423. Starting the adjusting motor 424 drives the adjusting gear 425 to rotate, which in turn drives the gear ring 426 to rotate synchronously with the adjusting orifice plate 423, adjusting the degree of overlap between the adjusting orifice plate 423 and the through groove of the guide orifice plate 422: the higher the degree of overlap, the greater the airflow; the lower the degree of overlap, the smaller the airflow, thus achieving precise control of the airflow at the inlet of the diversion pipe 4. Multiple branch pipes connected to the diversion pipe 4 have multiple assembly screw shells 41 fixed to the lower part of their outer wall, which are used to connect with the connecting corrugated pipe 57 of the outlet frame box 5 to realize the diversion and conduction of airflow.

[0057] The exhaust box 5, as the final uniform air distribution component, is used to evenly diffuse the split airflow into the laboratory room, avoiding local airflow concentration. Multiple exhaust boxes are set up and evenly assembled on the laboratory ceiling to achieve uniform air distribution throughout the entire area. The assembly slot 52 on one side of the exhaust box 5 is connected to the assembly clip 53 on the other side of the adjacent exhaust box 5 for assembly, which is convenient for flexible assembly according to the laboratory size to achieve full coverage air distribution. Multiple exhaust holes are opened through the bottom surface of the exhaust box 5 to blow the airflow evenly into the room and avoid the formation of concentrated airflow bundles. The screw 54 fixed to the bottom surface inside is threadedly assembled with the screw frame 55. The top of the screw frame 55 is fixed to the ceiling with bolts, and the installation height of the exhaust box 5 can be adjusted to adapt to different air distribution needs.

[0058] A sliding frame 51 fixed on one side inside the gas outlet box 5 is used for horizontally inserting the gas box 56. The corrugated pipe 57 at the top of the gas box 56 is threadedly connected to the assembly screw shell 41 of the diversion pipe 4 through a threaded joint, and is used to receive the airflow conducted by the diversion pipe 4. Multiple diversion hole cylinders 58 are fixed on the gas box 56 to further divert the airflow, so that the airflow is evenly distributed inside the gas outlet box 5, and then slowly and evenly diffused into the room through the gas outlet hole on the bottom surface, eliminating local airflow disturbance and ensuring stable airflow in the combustion area of ​​the gas stove.

[0059] During operation, the air conditioning system is first activated to generate airflow at a standard temperature of 20°C. The airflow is introduced into the gas delivery tube 14 through the gas delivery pipe 16, and then enters the regulating pipe 11 through the opening of the gas delivery tube 14. According to the laboratory temperature control requirements, the regulating electric cylinder 13 is activated to adjust the position of the gas delivery tube 14 and control the number of openings of the diverting tube 12 to achieve initial airflow diversion. The diverted airflow enters the flow-retarding tube 22, and the airflow is slowed down by the increasing diameter design of the flow-retarding tube 22 and the obstruction of the perforated plate 221. The slowed airflow is then collected in the guide tube 21 and introduced into the flexible tube 33 of the flow path regulating component 3. To meet the flow rate requirements, the air pump 35 is activated to adjust the inflation volume of the airbag ring cylinder 32, and the flow diameter of the flexible cylinder 33 is finely adjusted to further stabilize the airflow. The airflow enters the regulating cylinder 42 through the flexible cylinder 33, and after being diverted and stabilized by the guide plate 422 and the regulating plate 423, it enters the diversion pipe 4 and is then diverted to each assembly screw housing 41 through multiple branch pipes. The airflow enters the insert gas box 56 through the connecting corrugated pipe 57, and after being diverted again by the diversion cylinder 58, it is evenly diffused into the laboratory room through the gas outlet hole on the bottom surface of the gas outlet frame box 5, so as to stabilize the indoor temperature at 20℃ and avoid the airflow disturbing the combustion area of ​​the gas stove.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
