Description

Technical Field

[0001] This application relates to the field of ventilation equipment technology, specifically a mobile energy storage emergency ventilator based on temperature control and its working method. Background Technology

[0002] During mine operations, underground faces, confined spaces on the surface, and dead-end roadways are prone to accumulating harmful gases such as methane and dust due to their narrow spaces and poor air circulation. Furthermore, the geological environment further exacerbates these issues, severely impacting the safety and comfort of workers. Therefore, localized ventilation is a core aspect of safe mine production. Portable mine ventilation fans, as key equipment for localized ventilation, are widely used in various mines for temporary and emergency ventilation scenarios.

[0003] Currently, mine ventilation equipment is mainly divided into fixed main ventilation fans and portable local ventilation fans. Fixed main ventilation fans are large in size and cannot be moved. They are only suitable for overall mine ventilation and cannot meet the ventilation needs of local areas (such as temporary tunneling faces or emergency rescue sites). Portable local ventilation fans are small in size, easy to transport, and can be flexibly deployed in local areas, becoming the core equipment for local ventilation.

[0004] However, with the increase in mining depth and the complexity of the working environment, existing portable mine ventilation fans have gradually revealed many problems: First, they have a single function, only able to achieve ventilation and air exchange, and cannot simultaneously regulate the underground temperature. High temperatures in deep mines can easily lead to heatstroke among workers, while low temperatures in confined spaces above ground can easily cause equipment damage and frostbite to personnel. Second, the power supply is limited. Most portable ventilation fans rely on mains power. In the event of a sudden power outage, the equipment cannot operate normally, resulting in ventilation interruption and causing serious safety hazards such as gas accumulation. Third, if additional temperature control equipment, such as small air conditioners or electric heaters, is added, it will consume additional energy. At the same time, temperature control equipment is mostly electrical, which poses a risk of generating electric sparks and does not meet the explosion-proof requirements of mines.

[0005] In view of the above, in order to overcome the above technical problems, the present invention designs a mobile energy storage emergency ventilator based on temperature control and its working method, thus solving the above technical problems. Summary of the Invention

[0006] A mobile energy storage emergency ventilator based on temperature control includes a main body of equipment, and an air supply chamber, a distribution chamber, and a temperature regulating pipe installed inside the main body of equipment, wherein:

[0007] The air supply cavity includes an air supply assembly and a transmission mechanism, and the two ends of the air supply cavity are open.

[0008] One end of the diversion cavity is open, and the other end is sealed with a guide tube, which is connected to the air supply cavity. A pressurization component is installed inside the guide tube, and the transmission mechanism transmits the driving force of the air supply component to the pressurization component.

[0009] The temperature regulating tube includes a base tube, an air inlet pipe is provided between one end of the base tube and the converging end of the guide tube, and a hot air pipe and a cold air pipe are respectively provided at both ends of the base tube, and the air discharged from the hot air pipe and the cold air pipe can enter the air supply chamber independently.

[0010] Preferably, the base tube includes a fixed tube, and an outer sleeve is fitted around the fixed tube. The two ends of the outer sleeve are fixed to the base tube and the hot air pipe, respectively. An air inlet cavity is formed between the outer sleeve and the fixed tube. An inner channel is provided inside the fixed tube near the end of the hot air pipe. Multiple annularly distributed inclined grooves are provided on the wall of the inner channel, and the inclined grooves are connected to the inner channel and the air inlet cavity. An air inlet pipe is provided on one side of the outer sleeve and connected to the converging end of the guide tube. The two ends of the air inlet pipe are connected to the air inlet cavity and the guide tube, respectively.

[0011] Preferably, a three-way valve is installed at one end of the hot air duct and the cold air duct near the air supply chamber. An air inlet pipe is installed at one end of the three-way valve and extends into the interior of the air supply chamber. An exhaust pipe is installed at the other end of the three-way valve and extends into the exterior of the main body of the equipment.

[0012] Preferably, the air supply assembly includes a fixed frame, inside which a dual-axis motor is fixedly installed. A first rotating wheel is mounted on one output shaft of the dual-axis motor. The outer wall of the first rotating wheel is provided with annularly distributed air supply blades. The air discharged from the hot air duct and the cold air duct is located in front of the air supply blades.

[0013] Preferably, the pressurization component includes a second impeller, which is mounted on the lower end of the transmission mechanism via a bearing. The outer wall of the second impeller is provided with annularly distributed pressurization blades. The cross-section of one end of the guide tube is tapered, and the pressurization component is located at the end of the guide tube with a larger diameter. Multiple through holes are provided between the guide tube and the air supply cavity.

[0014] Preferably, the transmission mechanism has a transmission shaft installed inside via bearings, and both ends of the transmission shaft are provided with transmission helical gears. The other output end of the dual-shaft motor is equipped with a driving helical gear, and the rear end shaft of the second rotor is equipped with a driven helical gear. The driving helical gear and the driven helical gear are respectively meshed with the transmission helical gear.

[0015] Preferably, power supply components are installed on both sides of the lower end of the main body of the device. The power supply components include a high-efficiency battery pack, a fast charging module, and a power switching module, wherein:

[0016] The high-efficiency battery pack uses explosion-proof lithium batteries, and the explosion-proof lithium batteries can be connected in series to expand the capacity.

[0017] The fast charging module integrates a fast charging chip and an explosion-proof charging interface, and adopts dual charging modes of mains power and emergency power.

[0018] The power switching module is used for automatic switching between AC power and battery power.

[0019] Preferably, the air supply cavity is provided with folded air ducts at both ends, and flanges are provided at both ends of the folded air ducts. One flange is connected to the air supply cavity, and the other flange is used to combine other folded air ducts. The interior of the folded air duct is provided with multiple equidistantly distributed cross support frames. The multiple cross support frames are arranged counterclockwise from one direction to another at a fixed angle, and the included angle between the front and rear cross support frames is 8~10°.

[0020] Preferably, the front end of the main body of the device is hinged with a double front cabinet door, and the rear end of the main body of the device is hinged with a rear cabinet door at the position corresponding to the power supply component.

[0021] The operating method of a mobile energy storage emergency ventilator based on temperature control includes the following steps:

[0022] Step 1: Place the main body of the equipment in the mine operation area and switch the power supply mode according to the on-site power supply conditions. When the mains power is on, the battery pack of the power supply component is charged simultaneously. When there is no mains power or a sudden power outage, the power switching module automatically switches to battery power. Then unfold the foldable air duct and splice multiple sections of air duct as needed through the flange.

[0023] Step 2: Start the dual-shaft motor. One end of the output shaft drives the air supply blades to rotate and generate the main ventilation airflow. The other end drives the booster blades to rotate synchronously through the transmission mechanism.

[0024] Step 3: Part of the airflow in the air supply cavity enters the distribution cavity through the through hole, and after being centrifugally pressurized by the conical guide tube and the pressurizing blades, a high-pressure airflow is formed.

[0025] Step 4: The high-pressure airflow enters the air inlet cavity through the air inlet pipe, and enters the inner channel tangentially through the inclined slot to form a vortex. The airflow is separated into cold airflow and hot airflow, which are discharged from the cold air pipe and hot air pipe respectively.

[0026] Step 5: Adjust the three-way valve to switch the airflow path. When cooling, the cold airflow is introduced into the air supply chamber and the hot airflow is discharged from the main body of the equipment; when heating, the reverse is reversed. The valve opening can also be adjusted to achieve a mixing ratio of cold and hot air.

[0027] Step 6: During continuous operation of the equipment, the power supply component monitors the power supply status in real time. When the mains power is interrupted, it automatically switches to battery power. When the battery power is insufficient, it can be charged through the fast charging module or the battery pack can be expanded in series.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. This invention integrates ventilation and temperature control, eliminating the need for additional temperature control equipment. It uses a single power source to simultaneously drive the main ventilation and pressurization and temperature control functions, simplifying the overall structure. The hot and cold air output from the temperature control pipe can be independently controlled, allowing for flexible selection of cooling or heating based on ambient temperature, thus meeting the needs of confined spaces on the ground and mining environments at different depths.

[0030] 2. With a built-in explosion-proof battery pack, dual charging modes, and an automatic power switching module, the equipment is freed from the limitations of fixed cables, enabling portable and mobile emergency ventilation. It is suitable for scenarios without a fixed power source, such as sudden power outages, tunnel repairs, and rescue operations. Furthermore, automatic power switching ensures uninterrupted ventilation, avoiding major safety hazards such as gas accumulation and oxygen deficiency caused by power outages. Fast charging meets the needs of short-term, high-intensity continuous operation, and the battery can be connected in series to expand its capacity, adapting to different durations of operation tasks.

[0031] 3. The temperature regulating pipe adopts a double-layer sleeve combined with a tangential air inlet structure, which makes the high-pressure airflow form a high-speed vortex, realizes the separation of airflow energy, and has no moving parts, electrical components and refrigerant. It meets the requirements of mine explosion-proof, dust-proof and moisture-proof, and has a long service life and low maintenance cost.

[0032] 4. The foldable air duct is retractable and quick to assemble. The internal cross support frame ensures the radial strength of the air duct and can also form a spiral guide for airflow. At the same time, it can block large debris and eliminate the need for filter installation. It is suitable for local ventilation scenarios such as mine dead-end roadways and long-distance tunneling faces. Attached Figure Description

Detailed Implementation

[0046] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] Example 1:

[0048] like Figure 1-9 As shown, the mobile energy storage emergency ventilator based on temperature control includes a main body 1, and an air supply chamber 4, a diversion chamber 5, and a temperature regulating pipe 6 integrated inside the main body 1. The main body 1 serves as the overall installation carrier and is made of explosion-proof material, making it suitable for the harsh environment of mines.

[0049] The air supply chamber 4 has an open structure at both ends, serving as the main ventilation channel. An air supply assembly and a transmission mechanism 45 are installed inside. The air supply assembly includes a fixed frame 44, which is fixedly installed on the inner wall of the air supply chamber 4. A dual-axis motor 43 is bolted inside the fixed frame 44. The dual-axis motor 43 is an explosion-proof motor. A first rotating wheel 41 is keyed to one output shaft of the dual-axis motor 43. The outer wall of the first rotating wheel 41 is welded with uniformly distributed annular air supply blades 42. When rotating, it can draw in external air and form an axial main ventilation airflow to meet the air volume requirements of local ventilation.

[0050] The diversion chamber 5 is located on one side of the air supply chamber 4. One end of the diversion chamber 5 is open, and the other end is sealed and fixed with a guide tube 51. The upper end of the guide tube 51 is connected to the air supply chamber 4. The cross-section of one end of the guide tube 51 is tapered, with the large diameter end facing the inside of the diversion chamber 5 and the small diameter end being a converging end, which is connected to the temperature regulating pipe 6. A pressurization component is installed inside the guide tube 51. The pressurization component includes a second rotating wheel 52, which is mounted on the lower end of the transmission mechanism 45 through a bearing. The outer wall of the second rotating wheel 52 is welded with uniformly distributed annular pressurization blades 53. The pressurization blades 53 are clearance-fitted with the inner wall of the guide tube 51 to ensure the pressurization effect. Multiple through holes 55 are opened between the guide tube 51 and the air supply chamber 4. The through holes 55 are uniformly distributed in annular shape, allowing some of the airflow in the air supply chamber 4 to enter the diversion chamber 5 through the through holes 55, providing an airflow source for the pressurization component.

[0051] The transmission mechanism 45 is used to transmit the driving force of the air supply component to the pressurization component. The transmission mechanism 45 has a transmission shaft 451 installed inside through bearings. Both ends of the transmission shaft 451 are keyed to the transmission helical gears 452. The other output end of the dual-shaft motor 43 is keyed to the driving helical gear 46. The rear shaft of the second rotating wheel 52 is keyed to the driven helical gear 54. The driving helical gear 46 and the driven helical gear 54 are respectively meshed with the transmission helical gears 452 at both ends of the transmission shaft 451 to realize the transmission of power. This allows the air supply blades 42 and the pressurization blades 53 to be driven by the same dual-shaft motor 43, eliminating the need for an additional drive motor, simplifying the structure and reducing energy consumption.

[0052] The temperature regulating pipe 6 includes a base pipe 61. One end of the base pipe 61 is connected to the converging end of the guide tube 51 through an air inlet pipe 64. Both ends of the air inlet pipe 64 are sealed to the guide tube 51 and the base pipe 61 respectively to ensure that the airflow does not leak. The two ends of the base pipe 61 are integrally formed with a hot air pipe 62 and a cold air pipe 63. The air discharged from the hot air pipe 62 and the cold air pipe 63 can independently enter the air supply chamber 4 and mix with the main ventilation airflow to achieve temperature regulation.

[0053] Specifically, the base pipe 61 adopts a double-layer sleeve structure, including a fixed pipe 612 and an outer sleeve 615. The outer sleeve 615 is sleeved on the outside of the fixed pipe 612. The two ends of the outer sleeve 615 are welded and fixed to the base pipe 61 and the hot air pipe 62, respectively. An annular air inlet cavity 611 is formed between the outer sleeve 615 and the fixed pipe 612. The fixed pipe 612 has an inner channel 613 at the end near the hot air pipe 62. Multiple annularly distributed inclined grooves 614 are opened on the wall of the inner channel 613. The inclined grooves 614 are arranged inclined along the circumference of the fixed pipe 612 and are connected to the inner channel 613 and the air inlet cavity 611. The air inlet pipe 64 is welded to one side of the outer sleeve 615. The two ends of the air inlet pipe 64 are connected to the air inlet cavity 611 and the guide tube 51, respectively, so that the pressurized high-pressure airflow can enter the air inlet cavity 611.

[0054] High-pressure airflow first enters the air inlet cavity 611 through the air inlet pipe 64, and then enters the inner channel 613 tangentially through the annularly distributed inclined grooves 614 on the wall of the fixed pipe 612. The inclined grooves 614 are arranged at an angle along the circumference, so that the airflow enters the inner channel 613 in a high-speed swirling manner, forming a stable and high-intensity vortex field inside the inner channel 613. Under the action of the vortex, the airflow undergoes energy separation. The airflow temperature decreases near the central axis to form cold airflow, and the airflow temperature increases near the pipe wall to form hot airflow. They flow to both ends of the base pipe respectively, and are finally discharged from the cold air pipe 63 and the hot air pipe 62.

[0055] The double-layer sleeve combined with the tangential air inlet structure of the inclined groove 614 enables the high-pressure airflow to form a high-speed vortex; the inclined groove 614 is evenly distributed in an annular shape, which can avoid airflow deviation and pulsation; the air inlet cavity 611 plays a role in equalizing pressure, ensuring that the airflow pressure entering the inner channel 613 is uniform, and improving the consistency of temperature regulation; the whole is an integrated structure with no moving parts, no electrical components, and no refrigerant, which fully meets the requirements of mine explosion-proof, dust-proof, and moisture-proof, and has a long service life and extremely low maintenance cost.

[0056] Both the hot air duct 62 and the cold air duct 63 are equipped with a three-way valve 65 at one end near the air supply chamber 4. The three-way valve 65 is an explosion-proof manual or electric three-way valve, suitable for the mining environment. An air inlet pipe 66 is welded to one end of the three-way valve 65, which extends into the interior of the air supply chamber 4 and is located in front of the air supply blades 42, so that the hot and cold air can mix with the main ventilation airflow in the same direction. An exhaust pipe 67 is welded to the other end of the three-way valve 65, which extends to the outside of the main body 1 of the equipment and is used to exhaust useless hot and cold air. The airflow path is controlled by switching the valves: when cooling is required, the three-way valve 65 corresponding to the cold air duct 63 introduces cold air into the air supply chamber 4 through the corresponding air inlet pipe 66, and the three-way valve corresponding to the hot air duct 62 directly exhausts hot air to the outside of the equipment through the corresponding exhaust pipe 67. When heating is required, hot air is introduced into the air supply chamber 4 and cold air is exhausted to the outside. The valve opening can also be adjusted according to the temperature requirements to achieve a mixing ratio of hot and cold air.

[0057] It enables the direct exhaust of unused hot or cold air, preventing useless airflow from entering the main ventilation channel, ensuring that the main ventilation volume and air pressure are not weakened, and solving the problem of reduced ventilation capacity due to airflow diversion during temperature adjustment; hot and cold air are independently controllable, and the temperature adjustment mode switching is flexible and responsive, further improving work comfort and safety.

[0058] The lower part of the main body 1 of the equipment is equipped with power supply components 7 on both sides. Power supply components 7 include a high-efficiency battery pack, a fast charging module, and a power switching module. The high-efficiency battery pack uses explosion-proof lithium batteries. Multiple explosion-proof lithium batteries can be connected in series to expand capacity, increase voltage and capacity, and extend the working time of the equipment. The fast charging module integrates a fast charging chip and an explosion-proof charging interface, supporting dual charging modes of mains power and emergency power, and can achieve high-power rapid charging. The power switching module uses an explosion-proof control module that can monitor the mains power status in real time. When the mains power is interrupted, it automatically switches to battery power. When the mains power is restored, it automatically switches back to mains power and charges the battery pack simultaneously to ensure uninterrupted ventilation. The built-in explosion-proof battery pack frees the equipment from the limitation of fixed cables, realizing portable and mobile emergency ventilation, which is suitable for scenarios without fixed power sources such as sudden power outages, tunnel repairs, and rescues. Automatic power switching ensures uninterrupted ventilation and avoids major safety hazards such as gas accumulation and oxygen deficiency caused by power outages. Fast charging meets the needs of short-term high-intensity continuous operation, and the batteries can be connected in series to expand capacity and adapt to different durations of operation tasks.

[0059] The front end of the main body 1 of the equipment is hinged with a double front cabinet door 11. When closed, it can protect the internal components such as the temperature regulating pipe 6 and the air supply component, preventing dust and debris from entering. The rear end of the main body 1 is hinged with a rear cabinet door 12 corresponding to the position of the power component 7. When the rear cabinet door 12 is opened, the battery pack, charging interface and power switching module of the power component 7 can be directly inspected, replaced and charged, making the operation convenient.

[0060] The main body of the equipment 1 is equipped with four casters 2 at the bottom corners to facilitate moving the equipment.

[0061] Example 2:

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 10 and Figure 11 As shown, this embodiment provides a foldable air duct 3 adapted to the above-mentioned mobile energy storage emergency ventilation fan based on temperature control, which is used to extend the air supply distance, ensure air supply stability, and adapt to scenarios such as narrow spaces in mines and long-distance tunneling faces.

[0063] The foldable duct 3 is made of wear-resistant and flame-retardant polymer composite material, which combines flexibility and structural strength. It can be stretched and folded for easy handling and storage, while resisting the erosion of dust and humid environments and preventing air leakage due to duct damage.

[0064] Both ends of the folded air duct 3 are equipped with metal flanges 31, and the flanges 31 have evenly distributed bolt holes. One flange 31 is detachably connected to the opening end of the air supply chamber 4 by bolts, which is convenient for installation and disassembly. The other flange 31 can be connected with the flanges 31 of other folded air ducts 3 by bolts to realize the rapid splicing of multiple air duct sections. The air supply distance can be flexibly adjusted according to the ventilation needs of the work area, which can adapt to different lengths of tunnel faces, single-ended tunnels and other scenarios.

[0065] The foldable duct 3 has multiple equidistantly distributed cross support frames 32 inside. The cross support frames 32 are made of corrosion-resistant and high-strength metal material. The multiple cross support frames 32 are arranged in an orderly counterclockwise direction from one direction to the other. The included angle between two adjacent cross support frames 32 is controlled at 8~10°, forming a continuous spiral support structure.

[0066] The spiral cross support frame 32 effectively enhances the radial strength of the folded duct 3, preventing it from collapsing due to excessive airflow pressure during air delivery and ensuring unobstructed airflow. Furthermore, the spiral structure guides the airflow through the duct, reducing airflow resistance and improving delivery efficiency. It also blocks large debris such as plastic bags, gravel, and cotton fibers from entering the main body 1 and damaging components like the air supply blades 42 and the booster blades 53. This eliminates the need for additional filters at the duct inlet, simplifying the structure and reducing maintenance costs.

[0067] Example 3:

[0068] This embodiment provides a working method for a mobile energy storage emergency ventilator based on temperature control, according to Embodiments 1 and 2, including the following steps:

[0069] Step 1: Place the main body of the equipment 1 in the mine operation area. According to the on-site power supply conditions, switch the power supply mode through the power switching module. If there is mains power on site, use mains power supply. At the same time, the mains power charges the explosion-proof lithium battery pack of the power component 7 through the fast charging module. If there is no mains power on site or a sudden power outage occurs, the power switching module automatically switches to battery power supply to ensure normal equipment startup. Then unfold the foldable air duct 3. According to the ventilation distance requirements, splice multiple sections of foldable air duct 3 through flange 31 to ensure that the air supply range covers the operation area.

[0070] Step 2: Start the dual-axis motor 43. One output shaft of the dual-axis motor 43 drives the first rotating wheel 41 and the air supply blades 42 to rotate at high speed, drawing in external air and forming an axial main ventilation airflow. The main ventilation airflow flows along the air supply chamber 4, providing fresh air to the work area and expelling harmful gases such as methane and dust. At the same time, the other output shaft of the dual-axis motor 43 drives the transmission shaft 451 and the second rotating wheel 52 to rotate through the meshing of the driving helical gear 46, the transmission helical gear 452 and the driven helical gear 54, thereby driving the pressurizing blades 53 to rotate synchronously.

[0071] Step 3: Part of the main ventilation airflow in the air supply cavity 4 enters the diversion cavity 5 through the through hole 55 between the guide tube 51 and the air supply cavity 4. The airflow entering the diversion cavity 5 flows towards the large diameter end of the conical guide tube 51. Under the rotation of the pressurizing blades 53, the airflow is centrifugally pressurized and flows along the inner wall of the conical guide tube 51 towards the converging end. The airflow pressure gradually increases and finally forms a high-pressure airflow that meets the working requirements of the temperature regulating tube 6.

[0072] Step 4: The high-pressure airflow enters the air inlet cavity 611 of the temperature regulating pipe 6 through the air inlet pipe 64. The air inlet cavity 611 plays a role in equalizing and stabilizing the pressure of the high-pressure airflow, making the airflow pressure uniform. Subsequently, the high-pressure airflow enters the inner channel 613 tangentially through the inclined groove 614 on the wall of the fixed pipe 612. Since the inclined groove 614 is arranged inclined along the circumference, the airflow enters the inner channel 613 in a high-speed swirling manner, forming a stable and high-intensity vortex field inside the inner channel 613. Under the action of the vortex, the airflow undergoes energy separation. The airflow temperature near the central axis of the inner channel 613 decreases, forming a cold airflow, which flows towards the cold air duct 63. The airflow temperature near the pipe wall of the inner channel 613 increases, forming a hot airflow, which flows towards the hot air duct 62. Finally, the cold airflow is discharged from the cold air duct 63, and the hot airflow is discharged from the hot air duct 62.

[0073] Step 5: Adjust the three-way valves 65 on the hot air duct 62 and cold air duct 63 according to the temperature requirements of the working environment to switch the airflow path. When the underground temperature is too high and cooling is required, adjust the three-way valve 65 corresponding to the cold air duct 63 to allow the cold airflow to be introduced into the air supply chamber 4 through the air inlet pipe 66, mixed with the main ventilation airflow in the same direction, and then sent out to achieve cooling. At the same time, adjust the three-way valve 65 corresponding to the hot air duct 62 to allow the hot airflow to be discharged to the outside of the main body 1 through the exhaust pipe 67, so as to avoid the hot airflow entering the air supply chamber 4 and affecting the cooling effect. If the environment is in a confined space on the ground and the temperature is low, and heating is required, adjust the three-way valve 65 in the opposite direction to introduce the hot airflow into the air supply chamber 4 and discharge the cold airflow to the outside of the main body 1. If the temperature is within a suitable range, the opening of the three-way valve 65 can be adjusted to achieve a ratio of hot and cold air mixing, so that the air supply temperature reaches the optimal comfort level.

[0074] Step 6: During continuous operation of the equipment, the power switching module of the power supply component 7 monitors the mains power status in real time. If the mains power is suddenly interrupted, it will automatically switch to battery power to ensure uninterrupted ventilation. If the battery power is insufficient, it can be quickly charged by connecting to the mains power or emergency power through the fast charging module, or the explosion-proof lithium battery pack can be connected in series to extend the working time of the equipment.

10. A method for operating a mobile energy storage emergency ventilator based on temperature control as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Place the main body of the equipment (1) in the mine operation area and switch the power supply mode according to the on-site power supply conditions. When the mains power is supplied, the battery pack of the power supply component (7) is charged simultaneously. When there is no mains power or a sudden power outage, the power switching module automatically switches to battery power supply. Then unfold the foldable air duct (3) and splice multiple air duct sections as needed through the flange (31). Step 2: Start the dual-shaft motor (43). One end of the output shaft drives the air supply blades (42) to rotate to generate the main ventilation airflow, and the other end drives the booster blades (53) to rotate synchronously through the transmission mechanism (45). Step 3: Part of the airflow inside the air supply cavity (4) enters the diversion cavity (5) through the through hole (55), and after being centrifugally pressurized by the conical guide tube (51) and the pressurizing blades (53), a high-pressure airflow is formed; Step 4: The high-pressure airflow enters the air inlet cavity (611) through the air inlet pipe (64), and enters the inner channel (613) tangentially through the inclined groove (614) to form a vortex. The airflow is separated into cold airflow and hot airflow, which are discharged from the cold air pipe (63) and the hot air pipe (62) respectively. Step 5: Adjust the three-way valve (65) to switch the airflow path. When cooling, the cold airflow is introduced into the air supply chamber (4) and the hot airflow is discharged from the main body of the equipment (1). When heating, the reverse switching is performed. The valve opening can also be adjusted to achieve the mixing ratio of cold and hot air. Step 6: During continuous operation of the equipment, the power supply component (7) monitors the power supply status in real time. When the mains power is interrupted, it automatically switches to battery power. When the battery power is insufficient, it can be charged through the fast charging module or the battery pack can be expanded in series.
