Description

Technical Field

[0001] This invention relates to the field of indoor and outdoor ventilation technology, specifically to a ventilation component capable of internal cleaning. Background Technology

[0002] When a home ventilation system is activated, it replenishes indoor oxygen. As the human body constantly consumes oxygen, indoor oxygen levels decrease. Introducing fresh, oxygen-rich outdoor air increases the oxygen content of the indoor air. Additionally, it removes stale indoor air. Prolonged use of air conditioning can easily lead to various odors, such as sweat, body odor, and smoke. The ventilation system continuously refreshes the indoor air, promptly removing these odors and improving air quality, which is beneficial to health. Furthermore, during air conditioning cooling, the evaporator continuously condenses moisture and discharges it outdoors, causing moisture loss from the indoor air. The ventilation system replenishes the indoor air with fresh, humid outdoor air, thus maintaining humidity.

[0003] In the market, ventilation components draw outdoor air into the room through blowers. To ensure the cleanliness of the indoor space, multiple air filters are typically added to prevent outdoor dust from entering. However, dust accumulation is inevitable after this process. Long-term dust accumulation can clog the vents, affecting airflow. Furthermore, further detailed cleaning requires professional inspection and maintenance, causing inconvenience to users. Therefore, we propose a ventilation component that can be cleaned internally. Summary of the Invention

[0004] The purpose of this invention is to provide a ventilation component capable of internal cleaning, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ventilation component capable of internal cleaning, comprising a body, a cleaning structure, a windbreak structure, and a dust collection structure. A rear air filter is laid at the rear end of the body. A top cover is movably connected to the upper surface of the body via a hinge. A windbreak structure is provided in the middle of the inner side of the body. A dust collection structure is provided at the lower end of the body. A front air filter is laid at the front end of the body. Several negative pressure fans are mounted along the front air filter of the body. The dust collection structure includes a base plate and a back plate. The machine body comprises a base plate, a locking device, and a connecting plate. A horizontally distributed base plate is bolted to the bottom of the machine body, and a back plate is bent at the end of the base plate. A locking device is bolted along the crease of the base plate. A connecting plate is fixed to one side of the base plate along the locking device. The locking device also includes a hollow mounting bracket, an arc-shaped groove, a lock cylinder, a compression spring, and a side post. An arc-shaped groove is formed in the middle of the hollow mounting bracket on the side away from the back plate, and a lock cylinder is inserted into the middle of the hollow mounting bracket. A compression spring is attached to one end of the lock cylinder, and a side post is fixed to the lock cylinder along the arc-shaped groove.

[0006] Preferably, the included angle between the base plate and the back plate is 0-45°.

[0007] Preferably, the lock cylinder is elastically connected to the hollow mounting bracket via a compression spring, and the lock cylinder is embedded into the side groove of the connecting plate via a side post.

[0008] Preferably, the base plate is connected and fixed to the cleaning structure via a connecting plate, and the cleaning structure and the base plate are detachably connected.

[0009] Preferably, the cleaning structure includes a hollow plastic plate, a side-opening cover, an air connection nozzle, a barrier mesh, and a dust inlet trough. The hollow plastic plate is mounted on the bottom plate above the locking device. The end of the hollow plastic plate is movably connected to the side-opening cover via a hinge, and the side-opening cover covers the end of the lock cylinder. The dust inlet trough is provided on the side of the hollow plastic plate away from the back plate, and the air connection nozzle is connected to the side of the hollow plastic plate near the back plate. The dust inlet trough is distributed in a 0-90° slope shape, and the slope of the dust inlet trough is mounted above the connecting plate. Both the connecting plate and the dust inlet trough are provided with a side groove for the side post to be embedded.

[0010] Preferably, the hollow plastic plate is connected to the negative pressure fan through an air connection nozzle, and a barrier mesh is inserted into the middle of the air connection nozzle.

[0011] Preferably, the windproof structure includes a partition, reinforcing ribs, electric push rods, connecting arms, I-shaped baffles, windproof plates, and fastening bolts. The end of the partition is equipped with reinforcing ribs along the upper part of the machine body. Several electric push rods are laid on the rear air filter area of ​​the reinforcing ribs. Connecting arms are installed at the ends of the electric push rods. An I-shaped baffle is fixed to the end of the connecting arm away from the electric push rods, and a windproof plate is embedded in the inner side of the I-shaped baffle.

[0012] Preferably, the sides of the I-shaped baffles at the electric push rods on both sides are sealed by baffles, and the sides of the I-shaped baffles at the electric push rods on both sides are provided with several screw holes.

[0013] Preferably, the wind deflector is provided with several fastening bolts at both ends, and the fastening bolts are assembled and connected with the screw holes.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: When the ventilation component capable of internal cleaning is in use, the entire base plate and back plate serve as the bottom component of the device, with an included angle of 30°. The base plate adopts a horizontal design and is parallel and symmetrical to the top cover. During subsequent ventilation, some large particles and dirt fall onto the surface of the base plate, facilitating the user's need for cleaning and maintenance, ensuring a clean ventilation environment. Furthermore, the dust collection structure serves as the connecting component of the cleaning structure. The base plate and back plate adopt a bent forming design, and a locking device for securing the cleaning structure is provided along the edge of the back plate. The locking device is installed on the base plate using bolts, and the end of the lock cylinder is elastically fixed with a compression spring to reduce the possibility of automatic movement of the lock cylinder. The lock cylinder is also provided with a fixedly connected side post, which provides lateral restraint for the connecting plate and the hollow plastic plate, meeting basic positioning and locking requirements and facilitating user operation.

[0015] The entire hollow plastic panel is a cubic hollow plastic sheet. A dust inlet groove is opened at the front end of the hollow plastic panel to meet the subsequent negative pressure dust collection requirements. Simultaneously, the other end of the hollow plastic panel is connected to an air connection nozzle for creating a negative pressure environment. The nozzle's air outlet is close to the negative pressure fan. When the negative pressure fan blows air, the internal environment of the hollow plastic panel is in a negative pressure state. The airflow draws dust from the bottom surface into the hollow plastic panel. To prevent airborne dust from flowing into the front of the machine body through the air connection nozzle, a barrier is inserted in the middle of the air connection nozzle. The functional barrier mesh ensures the cleanliness of subsequent air delivery. The hollow plastic panel has a side cover at its end that shields the lock cylinder. By moving the side cover, it separates from the hollow plastic panel. The user can open the side cover to expose the lock cylinder, allowing the user to rotate it and rotate the side column. Once the side column is rotated above the arc-shaped groove, and the connecting plate and the dust inlet groove are unobstructed, the user can simply slide the cleaning structure. The cleaning structure can then be removed from above the base plate, allowing for close-range cleaning and emptying of the dust inside the cleaning structure, facilitating regular cleaning of the ventilation equipment.

[0016] This windbreak structure serves as a shield for the interior of the machine. When ventilation is not required, the windbreak completely isolates the machine from the outside, ensuring that the indoor and outdoor spaces do not interfere with each other. When the user needs to ventilate, they simply control the electric push rod to retract, which moves the connecting arm and the I-shaped baffle upwards, thereby moving the windbreak upwards to connect the indoor and outdoor spaces. At the same time, when the negative pressure fan blows air outwards, it allows the outside space to enter the room for air exchange, meeting the user's need for indoor air replacement.

[0026] Please see Figure 1-6This invention provides a technical solution: a ventilation component capable of internal cleaning, comprising a body 1, a cleaning structure 4, a windbreak structure 5, and a dust collection structure 6. A rear air filter 2 is laid at the rear end of the body 1. A top cover 3 is movably connected to the upper surface of the body 1 via a hinge. A windbreak structure 5 is located in the middle of the inner side of the body 1. A dust collection structure 6 is located at the lower end of the body 1. A front air filter 7 is laid at the front end of the body 1. Several negative pressure fans 8 are mounted along the front air filter 7 on the body 1. The dust collection structure 6 includes a base plate 601, a back plate 602, a locking device 603, and a connecting plate 604. The bottom of the body 1 is bolted with horizontally distributed base plates 601, and the ends of the base plates 601... The base plate 601 has a bent back plate 602, and a locking device 603 is bolted along the crease of the base plate 601. A connecting plate 604 is fixed to one side of the locking device 603 on the base plate 601. The locking device 603 also includes a hollow mounting bracket 6031, an arc groove 6032, a lock cylinder 6033, a compression spring 6034, and a side post 6035. An arc groove 6032 is formed on the side of the hollow mounting bracket 6031 away from the back plate 602, and the lock cylinder 6033 is inserted into the middle of the hollow mounting bracket 6031. One end of the lock cylinder 6033 is attached to the compression spring 6034, and the side post 6035 is fixed to the lock cylinder 6033 along the arc groove 6032. The included angle between the base plate 601 and the back plate 602 is [missing information]. The lock cylinder 6033 is elastically connected to the hollow mounting bracket 6031 via a compression spring 6034, and the lock cylinder 6033 is embedded into the side groove of the connecting plate 604 via a side post 6035. The bottom plate 601 is connected and fixed to the cleaning structure 4 via the connecting plate 604, and the cleaning structure 4 is detachably connected to the bottom plate 601. The entire bottom plate 601 and back plate 602 serve as the bottom components of the device, with an included angle of 30°. The bottom plate 601 adopts a horizontal design and is parallel and symmetrical to the top cover 3. During subsequent ventilation, some large particles and dirt fall onto the surface of the bottom plate 601, facilitating the subsequent cleaning and maintenance needs of the user, and ensuring the overall ventilation... The air environment is clean and hygienic, and the dust collection structure 6 serves as a connector for the cleaning structure 4. The base plate 601 and back plate 602 are designed with bending. A locking device 603 for locking and fixing the cleaning structure 4 is provided on the edge of the base plate 601 along the back plate 602. The locking device 603 is installed on the base plate 601 by bolt fastening. The end of the lock cylinder 6033 is provided with a compression spring 6034 that is elastically fixed to reduce the possibility of the lock cylinder 6033 moving automatically. The lock cylinder 6033 is provided with a fixedly connected side post 6035. The side post 6035 provides lateral limit for the connecting plate 604 and the hollow plastic plate 401, meeting the basic positioning and locking requirements and facilitating user use.

[0027] Please see Figure 4 and Figure 6As shown, the present invention provides a technical solution: a ventilation component capable of internal cleaning. The cleaning structure 4 includes a hollow plastic plate 401, a side-opening cover 402, an air connection nozzle 403, a barrier mesh 404, and a dust inlet 405. The hollow plastic plate 401 is mounted on the bottom plate 601 above the locking device 603. The end of the hollow plastic plate 401 is movably connected to the side-opening cover 402 via a hinge, and the side-opening cover 402 covers the end of the lock cylinder 6033. A dust inlet 405 is provided on the side of the hollow plastic plate 401 away from the back plate 602, and an air inlet is connected to the side of the hollow plastic plate 401 near the back plate 602. The connecting nozzle 403 and the ash inlet trough 405 are sloped at 0-45° and are positioned above the connecting plate 604. Both the connecting plate 604 and the ash inlet trough 405 have a side groove for the side column 6035 to be embedded. The hollow plastic plate 401 is connected to the negative pressure fan 8 via the air-connecting nozzle 403. A barrier net 404 is inserted into the middle of the air-connecting nozzle 403. The entire hollow plastic plate 401 is a cubic hollow plastic plate. The front end of the hollow plastic plate 401 has an ash inlet trough 405 to meet the subsequent negative pressure dust collection requirements of the hollow plastic plate 401. The other end of the hollow shaped plate 401 is connected to an air connection nozzle 403 for creating a negative pressure environment. The nozzle of the air connection nozzle 403 is close to the negative pressure fan 8. When the negative pressure fan 8 blows air, the internal environment of the hollow shaped plate 401 is in a negative pressure state. The airflow draws dust from the surface of the base plate 601 into the hollow shaped plate 401. To prevent dust in the air from flowing into the front end of the machine body 1 from the air connection nozzle 403, a barrier mesh 404 with a barrier function is inserted in the middle of the air connection nozzle 403 to ensure the cleanliness of subsequent air delivery. The end of the hollow shaped plate 401 is provided with a shielding lock. The side opening cover 402 of the core 6033 can be separated from the hollow plastic plate 401 by moving the side opening cover 402. The exposed lock cylinder 6033 can be rotated by the user, which in turn drives the side column 6035 to rotate. After the side column 6035 rotates to the top of the arc groove 6032 and the side groove of the connecting plate 604 and the dust inlet groove 405 are unobstructed, the cleaning structure 4 can be slid down and removed from the top of the base plate 601. This allows for close-range cleaning and emptying of the dust inside the cleaning structure 4, making it convenient for the user to clean the ventilation equipment regularly.

[0028] Please see Figure 1This invention provides a technical solution: an air exchange component capable of internal cleaning. The windbreak structure 5 includes a partition 501, reinforcing ribs 502, electric push rods 503, connecting arms 504, I-shaped baffles 505, wind deflectors 506, and fastening bolts 507. Reinforcing ribs 502 are installed at the ends of the partition 501 along the upper part of the body 1. Several electric push rods 503 are laid on the rear air filter 2 from the reinforcing ribs 502. Connecting arms 504 are installed at the ends of the electric push rods 503. An I-shaped baffle 505 is fixed to one end of the connecting arm 504 away from the electric push rods 503. A wind deflector 506 is embedded inside the I-shaped baffle 505. The sides of the I-shaped baffles 505 at the electric push rods 503 on both sides are sealed by the baffles. The I-shaped baffle 505 has several screw holes on its side, and the wind deflector 506 has several fastening bolts 507 at both ends. The fastening bolts 507 are connected to the screw holes. This wind deflector structure 5 serves as a component that shields the interior of the machine body 1. When ventilation is not required, the wind deflector 506 shields the entire space inside the machine body 1, isolating the machine body 1 from the external space, so that the indoor and outdoor spaces do not affect each other. When the user needs to perform ventilation, he only needs to control the electric push rod 503 to retract, which drives the connecting arm 504 and the I-shaped baffle 505 to move upward, thereby driving the wind deflector 506 to move upward, so that the indoor and outdoor spaces are connected. At the same time, when the negative pressure fan 8 blows air outward, the external space enters the room for air exchange, meeting the user's need for indoor air exchange.

[0029] Working principle: For this type of ventilation component capable of internal cleaning, the electric push rod 503 is first retracted, causing the connecting arm 504 and the I-shaped baffle 505 to move upward, which in turn causes the wind deflector 506 to move upward, connecting the indoor and outdoor spaces. Simultaneously, when the negative pressure fan 8 blows air outward, the external space enters the room for air exchange. During subsequent ventilation, some large particles and dirt fall onto the surface of the base plate 601. When the negative pressure fan 8 blows air, the internal environment of the hollow plastic plate 401 is under negative pressure. The airflow draws dust from the surface of the base plate 601 into the hollow plastic plate 401. Furthermore, to prevent dust from the air from being drawn out through the air connection nozzle 40... Air flows into the front of the body 1 from three points. A barrier mesh 404 with a barrier function is inserted into the middle of the air connection nozzle 403 to ensure the cleanliness of subsequent air delivery. Finally, by moving the side opening cover 402, the side opening cover 402 is separated from the hollow plastic plate 401. The user opens the side opening cover 402, exposing the lock cylinder 6033. The user can rotate the lock cylinder 6033, which in turn drives the side column 6035 to rotate. This allows the side column 6035 to rotate to the top of the arc groove 6032. After the connecting plate 604 and the side groove of the dust inlet trough 405 are unobstructed, the user only needs to slide the cleaning structure 4. The cleaning structure 4 is removed from the top of the base plate 601, allowing for close-range cleaning and emptying of the dust inside the cleaning structure 4.
