Description

Technical Field

[0001] The invention relates to the technical field of ventilation equipment, and in particular to a ventilation structure of a green building. Background Art

[0002] Green building refers to maximizing resource conservation, protecting the environment and reducing pollution throughout the entire life cycle of the building. Green building can provide a healthier, more comfortable and efficient use space. Green building technology has the advantages of low consumption, high efficiency, economy and environmental protection. The ventilation mechanism is a more important part of green building. During construction, the ventilation structure is generally set on the roof of the building. The ventilation structure can send outside air into the supporting pipe system. The pipe system can send outside air into the interior of the building and send the internal air out of the building to ventilate the interior of the building. The ventilation structure can provide a good ventilation environment for the interior of the building and ensure good air quality inside the building.

[0003] Climate conditions in different regions and seasons have significant differences in their impact on air humidity. Therefore, in green building design, air humidity regulation has become an important part of indoor environmental control. Flexible switching between humidification and dehumidification functions can effectively adapt to seasonal and regional climate changes.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] refer to Figure 1-Figure 8 , a ventilation structure of a green building, comprising: Ventilation duct 100; A connecting cavity 101 is disposed in the ventilation duct 100, a ventilation channel 102 is formed between the connecting cavity 101 and the ventilation duct 100, and an atomizing cavity 103 and a liquid cavity 104 are disposed in the connecting cavity 101; A plurality of shunt pipes 105 are provided at the top of the connecting cavity 101, and a plurality of steam ports 106 are provided on the shunt pipes 105; A plurality of steam platforms 107 are disposed in the atomizing chamber 103, a heating portion 108 is disposed at the bottom of the steam platform 107, and a plurality of spaces 109 are formed at the top of the steam platform 107; A plurality of groups of atomizing nozzles 110 are disposed in the atomizing chamber 103, and each group of atomizing nozzles 110 is disposed corresponding to a space 109 on a corresponding steam platform 107; An exhaust fan 111 disposed in the ventilation duct 100 is used to supply air to the building; A conveying component disposed between the liquid chamber 104 and the atomizing nozzle 110, used to convey liquid to the atomizing nozzle 110 when the ventilation channel 102 is opened, and the conveying component can convey liquid when the exhaust fan 111 is working; A humidifying component disposed between the atomizing chamber 103 and the steam platform 107, used to reciprocate the steam platform 107 when the ventilation channel 102 is opened, and the humidifying component can move the steam platform 107 when the exhaust fan 111 is working; A switching component is provided between the atomizing chamber 103 and the ventilation channel 102, and is used to switch the direction of the wind flow. When the switching component opens the ventilation channel 102, the atomizing chamber 103 is closed, and when the ventilation channel 102 is closed, the atomizing chamber 103 is opened. When the switching component closes the ventilation channel 102, the steam platform 107 is rotated so that the heating part 108 thereon is tilted toward the wind flow; By setting the exhaust fan 111, when in use, the ventilation duct 100 provides an air flow path, and the exhaust fan 111 is used to supply air to the interior of the building to ensure the circulation and freshness of the air. When it is necessary to humidify the space in the building, pure water can be poured into the liquid cavity 104, and the heating part 108 can be turned on, and the heat emitted by the heating part 108 is conducted to the steam platform 107. The provided conveying component can convey the liquid to the atomizing nozzle 110 when the ventilation channel 102 is turned on. The atomizing nozzle 110 corresponds to one of the spaces 109. When the liquid is atomized and sprayed on the steam platform 107, it will enter one of the spaces 109, and with the operation of the humidification component, the steam platform 107 is reciprocated on the predetermined path in the atomizing cavity 103. Through this reciprocating motion, the position of the space 109 on the steam platform 107 is constantly changing, avoiding excessive atomized liquid from being retained in a certain space 109, and ensuring that each space 109 has enough time to heat up after contacting the liquid. This design not only improves the efficiency of humidity regulation, but also prevents excess moisture from accumulating in the space 109, ensuring that the steam platform 107 can continuously and effectively release steam into the air, thereby maintaining the indoor air humidity within an ideal range. After the atomized liquid forms steam due to heat, the steam rises into the shunt pipe 105 and overflows from the steam port 106, combining with the wind flow generated by the exhaust fan 111. The wind flow of the exhaust fan 111 evenly brings the steam into the ventilation duct 100 and sends it into the building through the pipeline. The wind flow helps the steam to spread quickly throughout the space, ensuring that the humidity regulation is more uniform and efficient. Due to the fast mixing speed of steam and air, the indoor air humidity is rapidly improved, and the heat of the steam also helps to warm the air and enhance comfort. Through the cooperation of the wind flow, the steam can overcome the rising gravity, further promote the humidity distribution in the air, and keep the indoor humidity within an ideal range. In addition, the multiple shunt pipes 105 provided are helpful for the mixing of airflows, thereby ensuring the balanced distribution of humidity inside the entire building. When the building needs dehumidification, the wind flow direction can be switched by using the switching component. The switching component closes the ventilation channel 102 and opens the atomizing chamber 103, and the wind flow will first enter the atomizing chamber 103. At this time, the conveying component and the humidifying component stop working, the steam platform 107 no longer moves, and the atomizing nozzle 110 no longer sprays the atomized liquid. And let the steam platform 107 rotate and tilt toward the exhaust fan 111. The wind flow will enter the atomizing chamber 103 and blow toward the heating part 108, and after passing through the heating part 108, it will enter the shunt pipe 105 and be discharged from the steam port 106. The wind flow will transfer through the atomizing chamber 103, and the heating part 108 will be used to heat and dehumidify the air flow. The heating part 108 heats the air so that the moisture in the air is evaporated and taken away, thereby reducing the indoor humidity. In this way, the moisture in the air is effectively removed to ensure that the indoor humidity is properly controlled. The flow of wind through this path not only heats the air, but also enhances the dehumidification effect, ensuring the dryness and comfort of the air in the building.At the same time, the function of the switching component is to flexibly switch the humidification and dehumidification functions according to the humidity change requirements to adapt to the adjustment requirements in different environments. Through this precisely controlled wind flow and airflow path management, the air quality inside the entire building can be maintained at a stable and ideal level. Whether it is dehumidification when the humidity is too high or humidification when the humidity is too low, it can effectively meet the comfort requirements of the space. This application solves the shortcomings of traditional building ventilation systems in humidity regulation, especially the problem that indoor air quality is difficult to maintain stability under frequent changes in ambient humidity or extreme climatic conditions.

[0019] As a further solution of the present invention, the humidifying component includes a screw a200 rotatably connected to the atomizing chamber 103, a plurality of limit rods 201 are also connected to the atomizing chamber 103, a connecting block a202 is connected to the bottom of the steam platform 107, a connecting block b203 is rotatably connected to the bottom of the connecting block a202, part of the connecting block a202 is slidably connected to the limit rod 201, one of the connecting blocks b203 is threadedly connected to the screw a200, a spring a204 is provided between the connecting block a202 and the connecting block b203, and the screw a200 is a reciprocating screw; By setting the lead screw a200 as a reciprocating lead screw, the steam platform 107 can be reciprocated along a predetermined path in the atomizing chamber 103. The rotation of the lead screw a200 drives the connecting block b203 to slide along the threaded track of the lead screw a200, thereby promoting the relative movement between the connecting block a202 and the steam platform 107. The design of the lead screw a200 enables the steam platform 107 to reciprocate within a limited range, and the accuracy and stability of the reciprocating path can be controlled by the structure of the lead screw a200.

[0020] As a further solution of the present invention, the humidifying component further includes a connecting shaft 205 connected to the blade shaft of the exhaust fan 111, and a synchronous belt transmission mechanism 206 is provided between the connecting shaft 205 and the lead screw a200; By setting the connecting shaft 205, the blade shaft of the exhaust fan 111 can be connected to the screw a200 through the connecting shaft 205 and the synchronous belt transmission mechanism 206, so that when the exhaust fan 111 is working, the screw a200 can rotate synchronously to allow the steam platform 107 to move back and forth in the atomization chamber 103.

[0021] As a further solution of the present invention, the delivery component includes a connecting pipe 300 connected to the atomizing chamber 103, the atomizing nozzle 110 is connected to the connecting pipe 300, both ends of the connecting pipe 300 are connected to a delivery pipe 301 extending into the liquid chamber 104, a gas booster 302 is provided in the liquid chamber 104, and is used to deliver air to the liquid chamber 104 to increase the pressure in the liquid chamber 104, and the ventilation duct 100 is connected to a liquid inlet pipe 303 extending into the liquid chamber 104; By setting the connecting pipe 300, the two ends of the connecting pipe 300 are respectively connected to the delivery pipe 301 in the liquid cavity 104, ensuring that the liquid can be smoothly delivered to the atomizing nozzle 110, and then sprayed to form steam. This design can ensure that the liquid supply of the atomizing nozzle 110 is stable and the uniformity of the atomization effect is ensured. A gas booster 302 is provided in the liquid cavity 104, and its main function is to increase the pressure in the liquid cavity 104 by delivering air into the liquid cavity 104. The gas booster 302 can form a higher pressure in the liquid cavity 104, so that the liquid can enter the connecting pipe 300 under a greater pressure and spray through the atomizing nozzle 110, thereby promoting the atomization effect of the liquid. The high-pressure airflow can effectively increase the particle fineness of the atomization, improve the quality of the steam, and make the humidification effect more significant. The ventilation duct 100 is connected with a liquid inlet pipe 303 extending into the liquid cavity 104 to ensure that the liquid cavity 104 can stably receive liquid supply from the outside. Through the connection of the liquid inlet pipe 303, the liquid chamber 104 can continuously replenish the liquid to maintain the stability of the amount of liquid sprayed and the humidification efficiency. This design ensures that the liquid in the liquid chamber 104 is adequately supplied and forms a good match with other components, further improving the working efficiency and stability of the humidification system.

[0022] As a further solution of the present invention, the gas booster 302 includes an air pipe 304 connected to one side of the connecting cavity 101 and extending into the liquid cavity 104, a piston 305 is slidably connected in the air pipe 304, an air inlet a306 is provided on the piston 305, a baffle a307 is slidably connected to one side of the air inlet a306, a spring b308 is connected between the baffle a307 and the air inlet a306, an air inlet b309 is provided on one side of the air pipe 304, a baffle b310 is slidably connected to one side of the air inlet b309, a spring c311 is connected between the baffle b310 and the air inlet b309, a lead screw b312 threadedly connected to the piston 305 is rotatably connected to the air pipe 304, the lead screw b312 is a reciprocating lead screw, and a synchronous belt transmission mechanism 206 is also provided between the lead screw a200 and the lead screw b312; By setting a synchronous belt transmission mechanism 206, when the lead screw a200 rotates, the lead screw b312 can be driven to rotate synchronously, and the piston 305 can be moved. When the piston 305 moves, the baffle a307 on the air inlet a306 and the baffle b310 on the air inlet b309 will adjust their positions according to the force of the spring b308 and the spring c311, so as to realize the in and out control of the gas. In this way, the gas booster 302 can effectively increase the gas pressure in the liquid cavity 104, thereby pushing the liquid to enter the connecting pipe 300 and the atomizing nozzle 110 more efficiently, promoting the atomization of the liquid and improving the humidification effect.

[0023] As a further solution of the present invention, the switching component includes a connecting platform 400 connected to the connecting cavity 101, and a plurality of baffles 401 are rotatably connected to the connecting platform 400, a gear 402 is connected to the rotating shaft of one of the baffles 401, a rack 403 meshing with the gear 402 is connected to the connecting platform 400, and a chain transmission mechanism 404 is provided between every two adjacent baffles 401; By setting the rack 403, the gear 402 can be rotated by moving the rack 403 during application, so that one of the baffles 401 can be rotated. When one baffle 401 rotates, all the baffles 401 can be rotated through the chain transmission mechanism 404, forming a plate-like structure that can block the wind flow, thereby closing the air inlet and outlet of the ventilation channel 102.

[0024] As a further solution of the present invention, a cylinder 405 is connected to one side of the connecting cavity 101, and a connecting rod 406 connected to the rack 403 is connected to the telescopic shaft of the cylinder 405; The connecting shaft 205 includes a connecting rod a500 connected to the blade shaft of the exhaust fan 111, a connecting rod b501 is slidably connected to the connecting rod a500, the connecting rod b501 is rotatably connected to the connecting rod 406, a connecting rod c502 slidably connected to the connecting rod b501 is rotatably connected to one side of the connecting cavity 101, and a synchronous belt transmission mechanism 206 for driving the lead screw a200 is connected between the lead screw a200 and the connecting rod c502; By setting the structure of the cylinder 405 and the connecting rod 406, an effective driving force is provided for the movement of the rack 403. When the telescopic shaft of the cylinder 405 is connected to the connecting rod 406, the telescopic effect of the cylinder 405 can drive the movement of the connecting rod 406, thereby pushing the rack 403 to move along the predetermined path. This design ensures the precise control of the rack 403, so that the baffle 401 can be reasonably rotated as needed, and then the airflow path is adjusted to switch the humidification or dehumidification function. When the ventilation channel 102 is closed, due to the action of the cylinder 405, the connecting rod 406 drives the rack 403 to move, further affecting the relative position of the connecting rod b501. At this time, the connecting rod b501 can slide between the connecting rod a500 and the connecting rod c502, so that it gradually disengages from the connecting rod c502, thereby stopping the transmission between the lead screw a200 and the lead screw b312. This design ensures that when the rotation of the lead screw a200 needs to be stopped, it can be flexibly disconnected by sliding connection without affecting the normal operation of other components.

[0025] Optionally, a limiting structure for guiding, such as a notch, a slide groove, a pin guide, etc., may be provided on the connecting rod a500 and the connecting rod c502, so that the connecting rod a500, the connecting rod b501 and the connecting rod c502 are in a sliding engagement state to ensure that the sliding process of the connecting rod b501 is smooth and controllable.

[0026] As a further solution of the present invention, the switching component also includes a connection port 407 opened on one side of the atomizing chamber 103, a blocking frame 408 for blocking the connection port 407 is slidably connected in the connection port 407, the blocking frame 408 is connected to the connecting rod 406, and a partition 409 is connected in the connection cavity 101, and a regeneration desiccant is provided on the partition 409; By setting the blocking frame 408, when the ventilation channel 102 is in the open state, the connection port 407 is closed by the blocking frame 408 to block the entry of the airflow. When the cylinder 405 drives the connecting rod to move so that the ventilation channel 102 is closed, the blocking frame 408 moves with it and the connection port 407 can be opened. This design ensures that when the ventilation channel 102 is closed, the connection port 407 can be opened, thereby allowing the airflow to enter the atomizing chamber 103 for transfer and dehumidification; by setting the regenerated desiccant and the partition 409, the dehumidification effect can be further optimized. When the ventilation channel 102 is closed, the blocking frame 408 opens the connection port 407 to allow the airflow to flow into the atomizing chamber 103. When the airflow passes through the atomizing chamber 103, it will be adsorbed by the regenerated desiccant on the partition 409 to remove the moisture therein. When the humidification work is performed again in the subsequent period, the moisture therein can be released by heating the heating part 108. The heat provided by the heating unit 108 can evaporate the moisture in the desiccant, thereby restoring its moisture absorption capacity and ensuring that the system remains efficient during the next round of moisture removal. When the desiccant is regenerated, it will be able to effectively absorb moisture entering the atomization chamber 103 again, and continue to maintain the stability of air humidity through this process. In each cycle, the airflow not only removes moisture through the desiccant, but also releases the adsorbed moisture through the action of the heating unit 108, ensuring that the regeneration and use of the desiccant reaches the optimal state. This design effectively combines the ventilation, heating and desiccant regeneration functions, making the entire humidity regulation process more efficient, continuous and environmentally friendly.

[0027] As a further solution of the present invention, the switching component further includes a top rod 410 slidably connected to the atomizing chamber 103, a connecting strip 411 is rotatably connected to the top rod 410, a connecting frame 412 is connected to one side of the blocking frame 408, and the connecting strip 411 is rotatably connected to the connecting frame 412; By setting the connecting frame 412, when the connecting rod 406 moves to drive the blocking frame 408 to move, the connecting frame 412 can be moved together, so that the connecting strip 411 can touch the top rod 410, so that the top rod 410 moves upward, and when the top rod 410 moves upward, it can touch the bottom of the steam platform 107, so that the steam platform 107 can rotate a certain angle with the connecting block b203 as the center, so that the heating part 108 at the bottom can be tilted toward the wind flow, so that the wind flow can pass through the heating part 108 more concentratedly, improve the heating efficiency of the air, and enhance the dehumidification effect. It is worth noting that when the ventilation channel 102 is opened, the steam platform 107 is in a horizontal state, and when the atomization chamber 103 is opened, the steam platform 107 is in an inclined state. When the steam platform 107 is in a horizontal state, the atomized liquid can be evenly sprayed in the spaces 109 of the steam platform 107 and effectively retained by each space 109. Due to the horizontal state of the steam platform 107, the atomized liquid will not flow to one side due to gravity, thereby achieving efficient evaporation. The steam platform 107 is in an inclined state, so that the wind flow can directly hit the heating part 108. Such a design increases the contact area between the wind flow and the heating part 108. In addition, with the rotation and inclination of the steam platform 107, when the wind flow hits the heating part 108 at the bottom of the steam platform 107, most of the air flow can be directed to the regenerated desiccant, thereby further improving the air drying efficiency. Through such a design, the inclination and rotation of the steam platform 107 not only optimizes the air heating efficiency of the heating part 108, but also makes better use of the air flow to take away moisture, thereby increasing the moisture adsorption capacity of the regenerated desiccant. Through cooperation with the regenerated desiccant, when moisture passes through the desiccant, the moisture is effectively removed, thereby reducing the humidity of the air.

[0028] As a further solution of the present invention, the heating part 108 includes a heating wire 112 disposed at the bottom of the steam platform 107; By providing the heating wire 112 , the heating portion 108 can quickly generate heat and evenly distribute the heat at the bottom of the steam platform 107 , thereby effectively improving the heating efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
