Description

Technical Field

[0001] This invention belongs to the field of HVAC technology, specifically a low-pressure air-source hot water circulation energy-saving HVAC device. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is an integral part of building construction, encompassing heating, ventilation, and air conditioning. It also covers the fields of building environmental control, building energy conservation, and intelligent building facilities. HVAC systems include public utilities such as air conditioning, heating, ventilation, water supply and drainage, and gas supply. HVAC equipment is primarily used for indoor heating, and there are two types: hydronic and gas-fired. Hydronic heating uses a wall-mounted boiler or boiler to heat circulating water, creating a temperature difference with the radiators to form an indoor temperature difference, which is then circulated to raise the indoor temperature evenly. Gas-fired heating, on the other hand, heats the air, and the hot air circulates within the building to raise the indoor temperature.

[0003] When using air-cooled heating to heat indoor spaces, pressurization equipment is often used to directly draw in outside air, heat the air, and then deliver the warm air into the room. However, due to the complexity of the environment, such as the rainy season when the outside air is relatively humid and the autumn and winter seasons when the outside air is relatively dry, air humidity often affects the quality and heating effect of the output heating, reduces the practicality of HVAC equipment, and can easily cause harm to human health. Furthermore, if air humidity is not controlled in time, it can easily cause mold growth on building surfaces, blistering of walls, and other phenomena, seriously affecting the structural strength of the building.

[0004] In view of this, the present invention provides a low-pressure air-source hot water circulation energy-saving HVAC equipment, which improves the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem to be solved by this invention is that due to the complexity of the environment, such as the rainy season when the outside air is relatively humid and the autumn and winter seasons when the outside air is relatively dry, the air humidity often affects the output heating quality and heating effect, reduces the practicality of HVAC equipment, and is easy to cause harm to human health. Moreover, if the air humidity is not controlled in time, it can easily cause mold on the building surface, blistering of the wall, and other phenomena, which seriously affect the structural strength of the building.

[0006] The present invention provides a low-pressure air-source hot water circulation energy-saving HVAC equipment, which includes: a housing, a turbine, a humidity detector, a heating wire, and an adjustment device;

[0007] The turbine is located inside the housing, and a rotating shaft runs through the center of the turbine. One end of the rotating shaft is rotatably connected to the housing, and a drive device is fixedly installed at the other end of the rotating shaft. An air inlet is provided on the side of the housing near the turbine.

[0008] The humidity detector is fixedly installed inside the enclosure, and the humidity detector includes a humidity-sensitive resistor;

[0009] The heating wire is located on the side of the turbine away from the air inlet, and the heating wire is fixedly installed inside the housing;

[0010] An air outlet is provided on the housing, on the side of the heating wire away from the turbine;

[0011] The regulating device is located between the heating wire and the air outlet. The regulating device is installed inside the housing and is used to regulate the humidity of the warm air at the air outlet.

[0012] Compared to existing technologies, due to the complexity of the building environment, the air humidity often affects the output heating quality and heating effect when using HVAC equipment, reducing the practicality of HVAC equipment and easily causing harm to human health. Furthermore, the difficulty in controlling air humidity can easily cause mold growth on building surfaces, blistering of walls, and other phenomena, seriously affecting the structural strength of the building.

[0013] This invention detects air humidity using a humidity detector and adjusts the ventilation hole diameter of the device accordingly based on the air humidity value. This changes the residence time of the airflow near the heating wire, and the heating wire heats the airflow, evaporating some of the moisture in the airflow. This ensures that the humidity of the warm airflow is within the standard value, thereby guaranteeing the heating quality and effect, and also reducing the phenomenon of mold and blistering on building walls caused by excessive air humidity.

[0014] Preferably, the adjusting device includes: an electric telescopic rod, a folding frame, a partition, a movable block, an air inlet, and an air outlet;

[0015] The electric telescopic rod is provided in two parts, both of which are located inside the box and are respectively installed at the top and bottom of the box. The output ends of the two electric telescopic rods are arranged opposite to each other, and the electric telescopic rods are electrically connected to the humidity-sensitive resistor.

[0016] The folding frame is located between two electric telescopic rods. The folding frame includes multiple rectangular plates, connecting plates, and rotating rods. The multiple rectangular plates and connecting plates are connected end to end to form multiple "V" shapes through the rotating rods. The rectangular plates and connecting plates are rotatably connected to the rotating rods. The upper and lower ends of the folding frame are respectively fixed to the output ends of the two electric telescopic rods. The rectangular plates are set as hollow structures.

[0017] The rectangular plate has multiple partitions inside its cavity, and the multiple partitions are fixedly installed on the rectangular plate.

[0018] Multiple partitions form multiple movable slots between each other, and multiple movable blocks are provided. The multiple movable blocks are disposed in the movable slots and are movably connected in the movable slots.

[0019] An air inlet is provided on the lower surface of the rectangular plate. The air inlet communicates with the movable groove, and a waterproof and breathable membrane is installed inside the air inlet.

[0020] The upper surface of the rectangular plate is provided with an air outlet, which is connected to the movable groove. The air outlet and the air inlet do not completely overlap.

[0021] When heating is needed, the staff starts the drive unit and heating wires through the controller. The drive unit drives the turbine to rotate through the shaft. The turbine generates negative pressure, which draws outside air into the box through the air inlet. At the same time, the humidity detector detects the humidity of the air drawn into the box. After the air enters the box is heated by the heating wires, it is turned into warm air. Then, the warm air is pushed by the airflow on one side of the turbine and enters the cavity of the rectangular plate through the air inlet.

[0022] When the humidity detector detects that the air humidity is higher than the standard value, the air contains more water. This causes the resistance of the humidity-sensitive resistor to decrease, increasing the current in the circuit. Consequently, the output end of the electric telescopic rod extends, pushing the folding frame to fold. As the frame folds, the rectangular plate rotates, shifting the center of gravity towards the heating wire. The movable block rolls or slides towards the air inlet according to the center of gravity position. This reduces the connecting area between the air inlet and outlet, thus reducing the flow diameter of the heating air. Therefore, with a constant turbine speed, the heating airflow takes longer to pass through the regulating unit, resulting in a longer residence time near the heating wire. The moisture in the heating air is heated by the heating wire and gradually evaporates into water vapor, rising upwards. The remaining heating air passes through the air inlet, then through the movable block, and is discharged through the air outlet, thereby reducing the humidity of the heating system and ensuring heating quality.

[0023] Preferably, a filter plate is fixedly connected between the rectangular plate and the connecting plate.

[0024] After the airflow is heated by the heating wire, it is filtered by the filter plate, allowing the cleaner warm air to be discharged through the air inlet and outlet, reducing the particulate matter content in the warm air and ensuring the quality of the warm air and human health.

[0025] Preferably, the filter plate is made of a flexible metal sheet.

[0026] On the one hand, the filter plate is made of elastic metal sheet, which ensures the heat resistance and strength of the filter plate, while its elasticity provides room for the folding frame to be folded, ensuring the normal adjustment of the folding frame;

[0027] On the other hand, when the folding frame is folded, the filter plate is squeezed and bent with a large deformation arc. When the folding frame is extended, the squeezing force on the filter plate is reduced, and it recovers its elastic deformation by utilizing its own elasticity, reducing the deformation arc. In the process of recovering its elastic deformation by utilizing its elasticity, the filter plate can vibrate slightly. When the filter plate vibrates, it can shake off some of the dust attached to it, improving the service life of the filter plate and reducing the phenomenon of dust clogging the filter plate pores.

[0028] Preferably, a gas collecting pipe extends through the top of the housing, the gas collecting pipe is fixedly connected to the housing, the gas collecting pipe is located on the side of the folding frame away from the air outlet, a collection box is fixedly connected to the outer surface of the housing, and the gas collecting pipe and the collection box are connected by a condenser pipe.

[0029] When the airflow is heated by the heating wire, if the airflow has high humidity, it will have a high water content. When it is heated by the heating wire, some of the water will evaporate and produce water vapor that moves upward. At this time, the water vapor moves upward and enters the gas collecting pipe, and then condenses and liquefies through the condenser tube, becoming water droplets, which enter the collection box for collection, thus avoiding waste of resources.

[0030] Preferably, a water pipe is fixedly connected to the bottom of the collection box, the water pipe passes through the upper surface of the box and extends into the inside of the box, a nozzle is fixedly connected to the end of the water pipe away from the collection box, the nozzle is located above the air outlet, and a valve is fixedly installed at the connection between the collection box and the water pipe, the valve is electrically connected to a humidity-sensitive resistor.

[0031] When the humidity of the air in the turbine intake box is lower than the standard value, the resistance of the humidity-sensitive resistor increases, the output end of the electric telescopic rod retracts, the folding frame is stretched, the rectangular plate tilts at a larger angle, and the center of gravity of the folding frame is biased towards the air outlet side. The moving block rolls towards the air outlet side. At this time, the flow area between the air inlet and the air outlet increases, the heating time of the heating wire to heat the airflow is shortened, and at the same time, a small amount of moisture in the airflow is evaporated to ensure the humidity of the heating system.

[0032] If the humidity of the heating system at the air outlet is low and people want to increase the indoor humidity, they can open the valve in the water pipe. The water vapor condensed in the collection box becomes clean water. The water is then atomized and sprayed downwards through the nozzle. At the same time, driven by the air source at the air outlet, the atomized water droplets are discharged from the air outlet along with the heating system, thus regulating the indoor humidity.

[0033] At the same time, the clean water formed by the liquefaction of water vapor is stored and transported through pipelines for circulation, which is then used for heating and humidification in the later stages, thus achieving effective use of water resources and saving resources.

[0034] Preferably, a flow regulating valve is fixedly installed at the connection between the water pipe and the nozzle.

[0035] People can adjust the spray flow rate at the nozzles using the flow regulating valve, thereby adjusting the heating humidity to meet actual needs and improving the practicality of the equipment.

[0036] Preferably, the movable block is a solid adsorbent, and is a rigid, inelastic solid.

[0037] When the airflow passes through the air inlet and outlet, it passes through the movable block. Since the movable block is a solid adsorbent, it can adsorb odors or particulate matter in the airflow, further improving the heating quality.

[0038] Preferably, an adjusting blade is rotatably installed at the air outlet.

[0039] People can adjust the direction of the heating airflow by rotating the regulating blades, thus improving the practicality of the equipment.

[0040] The beneficial effects of this invention are as follows:

[0041] 1. The present invention provides a low-pressure air-source hot water circulation energy-saving HVAC equipment, which can sense the air humidity first by installing a humidity-sensitive resistor at the air inlet, and generate a corresponding resistance change according to the air humidity to control the heating humidity in real time.

[0042] 2. The present invention provides a low-pressure, air-source, hot water circulation, energy-saving HVAC device. The humidity-sensitive resistor is affected by air humidity, and the output of the electric telescopic rod is adjusted in real time. The center of gravity of the folding frame is adjusted, the position of the movable block in the movable slot is changed, the communication area between the air inlet and outlet is adjusted, and the flow rate of the airflow through the air inlet and outlet is changed. That is, the residence time of the airflow near the heating wire is changed, and the heating time of the heating wire is adjusted to evaporate some of the moisture in the airflow, ensuring that the humidity of the warm airflow is at the standard value, thereby ensuring the heating quality and heating effect, and also reducing the phenomenon of mold and blistering on the building walls caused by excessive air humidity.

[0043] 3. The present invention provides a low-pressure, air-source, hot water circulation, energy-saving HVAC equipment. By installing a filter plate at the folding frame, and the filter plate being made of elastic metal sheet, when the folding frame is stationary, the filter plate filters air particles, improving air quality. When the pneumatic telescopic rod adjusts the folding frame, the filter plate restores its elastic deformation, generating vibration, which shakes off the dust adhering to it, improving the service life of the filter plate and reducing the phenomenon of dust clogging the filter plate pores.

[0044] 4. The present invention provides a low-pressure air-source hot water circulation energy-saving HVAC equipment. When the air humidity is high, water vapor is generated when the heating wire heats the air. The water vapor undergoes a phase change through the condenser tube and liquefies into water droplets. The clean water is then collected by the collection tank, atomized by the nozzle, and discharged with the heating. The water droplets stored in the collection tank can work with the heating to form a humidifier during dry seasons such as autumn and winter, ensuring that the indoor humidity reaches the standard value. This saves energy and improves the practicality of the equipment, making it suitable for use in situations with lower humidity.

[0045] 5. The present invention provides a low-pressure air-collecting type hot water circulation energy-saving HVAC equipment, which has a flow regulating valve installed at the nozzle, which can adjust the spray flow of the nozzle according to the actual needs of heating humidity.

[0046] 6. The present invention provides a low-pressure air-collecting hot water circulation energy-saving HVAC equipment, by setting the movable block as a solid adsorbent. When the airflow passes through the air inlet and air outlet, it passes through the movable block. Since the movable block is a solid adsorbent, it can adsorb odors or particulate matter in the airflow, thereby further improving the heating quality.

[0047] Meanwhile, the movable incense block can also be a solid incense block. When the solid incense block evaporates, the fragrance can be discharged from the air outlet along with the heating, improving the indoor environment. Attached Figure Description

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] like Figures 1 to 3 As shown, the present invention provides a low-pressure air-source hot water circulation energy-saving HVAC equipment, which includes: a housing 1, a turbine 2, a humidity detector, a heating wire 4, and an adjustment device 5;

[0059] The turbine 2 is located inside the housing 1. A rotating shaft runs through the center of the turbine 2. One end of the rotating shaft is rotatably connected to the housing 1, and a drive device is fixedly installed at the other end of the rotating shaft. An air inlet 6 is provided on one side of the housing 1 near the turbine 2.

[0060] The humidity detector is fixedly installed inside the housing 1, and the humidity detector includes a humidity-sensitive resistor 3;

[0061] The heating wire 4 is located on the side of the turbine 2 away from the air inlet 6, and the heating wire 4 is fixedly installed inside the housing 1;

[0062] An air outlet 7 is provided on the housing 1 and on the side of the heating wire 4 away from the turbine 2;

[0063] The regulating device 5 is located between the heating wire 4 and the air outlet 7. The regulating device 5 is installed inside the housing 1 and is used to regulate the humidity of the warm air at the air outlet 7.

[0064] By adopting the above technical solution, when heating is required, the staff starts the drive equipment through the controller. The drive equipment drives the turbine 2 to rotate through the shaft. The rotation of the turbine 2 draws outside air into the box 1 through the air inlet 6. At the same time, the humidity detector detects the humidity of the air drawn into the box 1. After the air entering the box 1 is heated by the heating wire 4, it is transformed into warm air. Then, the warm air is pushed into the regulating device 5 by the airflow. According to the detection result of the humidity detector, the regulating device 5 adjusts the corresponding ventilation hole diameter, thereby changing the flow time of the airflow from the heating wire 4 through the regulating device 5. By controlling the flow time of the airflow, the continuous heating time of the airflow by the heating wire 4 is changed. If the air humidity is greater than the standard value, the ventilation hole diameter of the regulating device 5 is reduced, and the warm air in the box 1 takes a longer time to pass through the regulating device 5, so that the warm air stays around the heating wire for a longer time. As a result, the heating time of the heating wire on the warm air is longer, and the water content in the warm air evaporates more, thereby reducing the humidity of the heating air.

[0065] Compared to existing technologies, due to the complexity of the building environment, the air humidity often affects the output heating quality and heating effect when using HVAC equipment, reducing the practicality of HVAC equipment and easily causing harm to human health. Furthermore, the difficulty in controlling air humidity can easily cause mold growth on building surfaces, blistering of walls, and other phenomena, seriously affecting the structural strength of the building.

[0066] The present invention detects air humidity using a humidity detector and adjusts the ventilation hole diameter of the device 5 accordingly based on the air humidity value. This changes the residence time of the airflow near the heating wire, and the heating wire heats the airflow, evaporating some of the moisture in the airflow. This ensures that the humidity of the warm airflow is within the standard value, thereby guaranteeing the heating quality and effect, and also reducing the phenomenon of mold and blistering on building walls caused by excessive air humidity.

[0067] like Figures 1 to 7 As shown, the adjustment device 5 includes: an electric telescopic rod 51, a folding frame 52, a partition 53, a movable block 54, an air inlet 55, and an air outlet 56;

[0068] Two electric telescopic rods 51 are provided. Both electric telescopic rods 51 are located inside the housing 1 and are respectively installed at the top and bottom of the housing 1. The output ends of the two electric telescopic rods 51 are arranged opposite to each other. The electric telescopic rods 51 are electrically connected to the humidity-sensitive resistor 3.

[0069] The folding frame 52 is located between two electric telescopic rods 51. The folding frame 52 includes multiple rectangular plates 521, connecting plates 522, and rotating rods. The multiple rectangular plates 521 and connecting plates 522 are connected end to end to form multiple "V" shapes through the rotating rods. The rectangular plates 521 and connecting plates 522 are rotatably connected to the rotating rods. The upper and lower ends of the folding frame 52 are respectively fixed to the output ends of the two electric telescopic rods 51. The rectangular plates 521 are set as hollow structures.

[0070] The rectangular plate 521 has a plurality of partitions 53 disposed inside the cavity, and the plurality of partitions 53 are fixedly installed on the rectangular plate 521;

[0071] Multiple partitions 53 form multiple movable slots between each other, and multiple movable blocks 54 are provided. The multiple movable blocks 54 are disposed in the movable slots and are movably connected in the movable slots.

[0072] The lower surface of the rectangular plate 521 is provided with an air inlet 55, which is connected to the movable groove, and a waterproof and breathable membrane is installed inside the air inlet 55.

[0073] The upper surface of the rectangular plate 521 is provided with an air outlet 56, which communicates with the movable groove, and the air outlet 56 does not completely overlap with the air inlet 55.

[0074] By adopting the above technical solution, when heating is required, the staff starts the drive equipment and the heating wire 4 through the controller. The drive equipment drives the turbine 2 to rotate through the shaft. The rotation of the turbine 2 generates negative pressure, which draws the outside air of the box 1 into the box 1 through the air inlet 6. At the same time, the humidity detector detects the humidity of the air drawn into the box 1. After the air entering the box 1 is heated by the heating wire 4, it is transformed into warm air. Then, the warm air is pushed by the airflow on one side of the turbine 2 and enters the cavity of the rectangular plate 521 through the air inlet 55.

[0075] When the humidity detector detects that the air humidity is higher than the standard value, the air contains more water, the resistance of the humidity-sensitive resistor 3 decreases, and the current in the circuit increases. Consequently, the output end of the electric telescopic rod 51 extends, pushing the folding frame 52 to fold. When the folding frame 52 folds, the rectangular plate 521 rotates. As the rectangular plate 521 rotates, the center of gravity of the folding frame 52 shifts towards the heating wire 4. The movable block 54 rolls or slides towards the air inlet 55 according to the position of the center of gravity. Since the air inlet 55 and the air outlet 56 are not completely aligned, the movement of the movable block 54 reduces the pressure on the air inlet 55. The increased communication area with the air outlet 56 reduces the flow diameter of the heating air. As a result, under the premise of a constant turbine speed, the heating air takes a longer time to pass through the regulating unit, and thus the heating air stays near the heating wire 4 for a longer period of time. The moisture in the heating air is heated by the heating wire 4 and gradually evaporates into water vapor. At the same time, the waterproof and breathable membrane at the air inlet 55 can block the water vapor from passing through the air inlet 55, so the water vapor can only move upward. The heated air passes through the waterproof and breathable membrane, then through the air inlet 55, and then through the movable block 54 and is discharged through the air outlet 56, thereby reducing the humidity of the heating air and ensuring the quality of the heating air.

[0076] like Figure 1 and Figure 7 As shown, a filter plate 8 is fixedly connected between the rectangular plate 521 and the connecting plate 522;

[0077] By adopting the above technical solution, the airflow is heated by the heating wire and then filtered by the filter plate 8, so that the relatively clean heating air is discharged through the air inlet 55 and the air outlet 56, reducing the particulate matter content in the heating air and ensuring the quality of the heating air and human health.

[0078] The filter plate 8 is made of a flexible metal sheet;

[0079] By adopting the above technical solution, on the one hand, the filter plate 8 is made of elastic metal sheet, which ensures the heat resistance and strength of the filter plate 8, and on the other hand, its elasticity can provide room for the folding of the folding frame 52, ensuring the normal adjustment of the folding frame 52.

[0080] On the other hand, when the folding frame 52 is folded, the filter plate 8 is squeezed and bent with a large deformation arc. When the folding frame 52 is extended, the squeezing force on the filter plate 8 is reduced, and it recovers its elastic deformation by utilizing its own elasticity, thus reducing the deformation arc. In the process of recovering its elastic deformation by utilizing its elasticity, the filter plate 8 can vibrate slightly. When the filter plate 8 vibrates, it can shake off some of the dust attached to it, thereby improving the service life of the filter plate 8 and reducing the occurrence of dust clogging the filter pores of the filter plate 8.

[0081] like Figures 1 to 3As shown, a gas collecting pipe 9 runs through the top of the box 1. The gas collecting pipe 9 is fixedly connected to the box 1. The gas collecting pipe 9 is located on the side of the folding frame 52 away from the air outlet 7. A collection box 10 is fixedly connected to the outer surface of the box 1. The gas collecting pipe 9 and the collection box 10 are connected through a condenser pipe 11.

[0082] By adopting the above technical solution, when the airflow is heated by the heating wire, if the airflow has high humidity, it will have a large water content. When it is heated by the heating wire, some of the water will evaporate and generate water vapor that moves upward. At this time, the water vapor moves upward into the gas collecting pipe 9, and then condenses and liquefies through the condenser pipe 11, becoming water droplets, which are collected in the collection box 10, thus avoiding resource waste.

[0083] like Figure 1 As shown, a water pipe 12 is fixedly connected to the bottom of the collection box 10. The water pipe 12 passes through the upper surface of the box body 1 and extends into the interior of the box body 1. A nozzle 13 is fixedly connected to the end of the water pipe 12 away from the collection box 10. The nozzle 13 is located above the air outlet 7. A valve is fixedly installed at the connection between the collection box 10 and the water pipe 12. The valve is electrically connected to the humidity-sensitive resistor 3.

[0084] By adopting the above technical solution, when the humidity of the air drawn into the housing 1 by the turbine 2 is lower than the standard value, the resistance of the humidity-sensitive resistor 3 increases, the output end of the electric telescopic rod 51 retracts, the folding frame 52 is stretched, the tilt angle of the rectangular plate 521 is larger, and the center of gravity of the folding frame 52 is biased towards the air outlet 7. The movable block 54 rolls towards the air outlet 7. At this time, the flow area of ​​the air inlet 55 and the air outlet 56 increases, the heating time of the heating wire 4 to heat the airflow is shortened, and at the same time, less moisture in the airflow is evaporated to ensure the humidity of the heating system.

[0085] If the humidity of the heating system at the air outlet 7 is low and people want to increase the indoor humidity, they can open the valve in the water pipe 12. The water vapor condensed and liquefied in the collection box 10 becomes clean water. At this time, the water is atomized and sprayed downwards through the nozzle 13. At the same time, driven by the air source at the air outlet 7, the atomized water droplets are discharged from the air outlet 7 along with the heating system, thus regulating the indoor humidity.

[0086] At the same time, the clean water formed by the liquefaction of water vapor is stored and transported through pipelines for circulation, which is then used for heating and humidification in the later stage, so as to realize the effective use of water resources and save resources.

[0087] While saving energy, the equipment is also adapted to use in low humidity conditions.

[0088] A flow regulating valve is fixedly installed at the connection between the water pipe 12 and the nozzle 13;

[0089] By adopting the above technical solution, people can adjust the spray flow rate at nozzle 13 according to the flow regulating valve, thereby adjusting the heating humidity to meet actual needs and improving the practicality of the equipment.

[0090] The movable block 54 is a solid adsorbent, and it is a rigid, inelastic solid;

[0091] By adopting the above technical solution, when the airflow passes through the air inlet 55 and the air outlet 56, it passes through the movable block 54. Since the movable block 54 is a solid adsorbent, it can adsorb odors or particulate matter in the airflow, thereby further improving the heating quality.

[0092] like Figure 1 and Figure 3 As shown, an adjusting blade 14 is rotatably installed at the air outlet 7;

[0093] By adopting the above technical solution, people can adjust the direction of the heating air by rotating the adjusting blade 14, thereby improving the practicality of the equipment.

[0094] Working principle:

[0095] When heating is needed, the staff starts the drive device and the heating wire 4 through the controller. The drive device drives the turbine 2 to rotate through the shaft. The rotation of the turbine 2 generates negative pressure, which draws the outside air of the box 1 into the box 1 through the air inlet 6. At the same time, the humidity detector detects the humidity of the air drawn into the box 1. After the air entering the box 1 is heated by the heating wire 4, it is turned into warm air. Then the warm air is pushed by the airflow on one side of the turbine 2 and enters the cavity of the rectangular plate 521 through the air inlet 55.

[0096] When the humidity detector detects that the air humidity is higher than the standard value, the air contains more water, the resistance of the humidity-sensitive resistor 3 decreases, and the current in the circuit increases. Consequently, the output end of the electric telescopic rod 51 extends, pushing the folding frame 52 to fold. When the folding frame 52 folds, the rectangular plate 521 rotates. As the rectangular plate 521 rotates, the center of gravity of the folding frame 52 shifts towards the heating wire 4. The movable block 54 rolls or slides towards the air inlet 55 according to the position of the center of gravity. Since the air inlet 55 and the air outlet 56 are not completely aligned, the movement of the movable block 54 reduces the pressure on the air inlet 55. The increased communication area with the air outlet 56 reduces the flow diameter of the heating air. As a result, under the premise of a constant turbine speed, the heating air takes a longer time to pass through the regulating unit, and thus the heating air stays near the heating wire 4 for a longer period of time. The moisture in the heating air is heated by the heating wire 4 and gradually evaporates into water vapor. At the same time, the waterproof and breathable membrane at the air inlet 55 can block the water vapor from passing through the air inlet 55, so the water vapor can only move upward. The heated air passes through the waterproof and breathable membrane, then through the air inlet 55, and then through the movable block 54 and is discharged through the air outlet 56, thereby reducing the humidity of the heating air and ensuring the quality of the heating air.

[0097] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
