Description

Technical Field

[0001] This utility model relates to a wall-mounted fresh air device, specifically a wall-mounted fresh air device, belonging to the field of fresh air machine technology. Background Technology

[0002] Wall-mounted fresh air systems for distribution ring main units are designed specifically to improve the internal environment of these units. They are typically wall-mounted, taking up minimal space and easily installed on the side of the ring main unit or other suitable locations. Their working principle involves drawing in outside air through a fan, filtering it through a filter to remove dust and other impurities. Some units also have dehumidification and cooling functions, effectively preventing condensation within the ring main unit to improve its reliability and safety, reduce accidents such as malfunctions or failures to operate due to condensation, lessen the workload of maintenance personnel, and improve maintenance efficiency.

[0003] The prior art patent application number (201720547004.0), entitled "Wall-mounted Fresh Air System," includes: a housing; within the housing are two mutually isolated chambers, a first chamber and a second chamber; the first chamber has an air inlet, and a pre-filter, an electronic purification unit, and an activated carbon filter are sequentially arranged near the air inlet; the activated carbon filter contains several activated potassium permanganate balls; a fan is located within the first chamber, with its air inlet near the air outlet of the activated carbon filter; the fan's air outlet is connected to the second chamber via a duct; and the second chamber has an adjustable exhaust vent. A detector for detecting indoor CO2 levels is located on the outside of the housing, along with an electrical box that controls the fan's operation based on the detected indoor CO2 levels. The detector, fan, and electrical box are electrically connected. The beneficial effects of this wall-mounted fresh air system are that it effectively purifies outdoor air, rationally introduces fresh air, and reduces energy consumption.

[0004] However, its filter mechanism adopts a fixed installation method, which not only makes it difficult to quickly disassemble the filter mechanism after long-term use, which accumulates a large amount of impurities, causing great inconvenience to daily maintenance and periodic replacement, but also affects the overall operating efficiency of the equipment due to the excessive time spent on disassembly. More importantly, it completely lacks a special cleaning structure for the filter mechanism, which directly leads to the inability to remove the impurities trapped during the filtration process in a timely manner. As the usage time increases, impurities will continue to accumulate on the surface of the filter element, gradually clogging the filter channel, thereby significantly reducing the filtration effect, and may even increase the operating load of the equipment due to excessive resistance, shortening the service life of the equipment. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the Invention

[0005] The purpose of this utility model is to provide a wall-mounted fresh air device to solve the above-mentioned problems, so as to solve the problem that the filter mechanism in the prior art adopts a fixed installation method, which brings great inconvenience to daily maintenance and periodic replacement, and causes the impurities trapped in the filtration process to be unable to be removed in time, and the impurities will continue to accumulate on the surface of the filter element and gradually block the filter channel.

[0006] This utility model is achieved through the following technical solution: a wall-mounted fresh air device.

[0007] The device includes a housing, with an air inlet pipe fixedly connected to the bottom of the housing, two dust exhaust pipes fixedly connected to the bottom of the housing, three dust baffles fixedly connected to the bottom of the inner cavity of the housing, an air pump fixedly connected to the inner cavity of the housing, an exhaust pipe fixedly connected to the bottom of the air pump, the bottom end of the exhaust pipe extending to the bottom of the housing, and a mounting base provided on the top of the housing. The housing serves as the basic frame of the entire device, providing stable installation space for the internal components. The air inlet pipe is responsible for introducing the gas to be treated, the dust exhaust pipes can promptly discharge the filtered and separated dust and impurities, the dust baffles can effectively prevent the back diffusion of dust, the air pump provides power for the gas flow, and the exhaust pipes export the purified gas. All components work together to form a complete gas treatment pathway.

[0008] Preferably, three filter plates are screwed to the bottom of the mounting base. The bottom of the filter plates extends into the inner cavity of the housing, and the filter plates are in contact with the dustproof baffle. The filter plates are connected to the mounting base by screwing, which not only ensures the stability of the installation, but also facilitates quick disassembly and replacement when the filter plates are clogged or damaged, reducing maintenance difficulty. The setting of three filter plates increases the filtration area and improves the filtration efficiency. The design of the filter plates being in contact with the dustproof baffle further enhances the sealing effect, prevents unfiltered gas from flowing directly, and ensures thorough filtration.

[0009] Preferably, a transmission chamber is fixedly connected to the inner cavity of the housing, and a gear driven rod is rotatably connected to the inner cavity of the transmission chamber. One end of the gear driven rod passes through the transmission chamber and extends to one side of the outermost filter plate. Three sets of cleaning brushes are fixedly connected to the outer side of the gear driven rod. The cleaning brushes contact the filter plate and the dust baffle. The transmission chamber provides a stable rotational support environment for the gear driven rod. When the gear driven rod drives the cleaning brushes to rotate, the cleaning brushes can fully contact the filter plate and the dust baffle, promptly removing dust and impurities attached to the surface of the filter plate and the dust baffle, avoiding the accumulation of impurities and clogging, effectively maintaining the filtration performance of the filter plate and the blocking effect of the dust baffle, and extending the cleaning cycle of the components.

[0010] Preferably, a waterproof motor is fixedly connected to the top of the housing, and a gear drive rod is fixedly connected to the bottom end of the power output shaft of the waterproof motor. The bottom end of the gear drive rod passes through the housing and the transmission chamber and extends into the inner cavity of the transmission chamber. The bottom end of the gear drive rod is meshed with the gear driven rod. The waterproof motor serves as a power source, and through the meshing transmission of the gear drive rod and the gear driven rod, the power is stably transmitted to the cleaning brush, realizing the automated rotation and cleaning of the cleaning brush. This eliminates the need for manual cleaning, saves labor costs, ensures the continuity and stability of the cleaning operation, and improves the automation level of the equipment.

[0011] Preferably, both sides of the housing are fixedly connected to a docking compartment, and a first-phase magnet is fixedly connected to the bottom of the inner cavity of the docking compartment. The inner cavity of the docking compartment has an annular groove, and the top of the docking compartment has a through groove. The docking compartment provides a precise docking structure for the connection between the mounting base and the housing. The first-phase magnet can generate an attractive force with the corresponding component on the mounting base, enhancing the stability of the connection. The annular groove can limit the connection component of the mounting base, and the through groove provides a channel for the insertion of the connection component, ensuring that the mounting base can quickly and accurately dock with the housing.

[0012] Preferably, mounting plates are fixedly connected to both sides of the mounting base, and a rotating rod is rotatably connected to the inner side of the mounting plate. The bottom end of the rotating rod extends through the through groove to the inner cavity of the docking compartment, and a second phase magnet is fixedly connected to the bottom end of the rotating rod. The mounting plate provides stable mounting support for the rotating rod, which can rotate flexibly within the mounting plate, facilitating the connection or separation with the docking compartment by adjusting its position. The second phase magnet attracts the first phase magnet in the docking compartment, enabling rapid initial fixation of the mounting base to the housing. Combined with the structural design of the rotating rod, the mounting base can be installed and removed more conveniently and efficiently.

[0013] Preferably, the second phase magnet is attracted to the first phase magnet, and two locking rods are fixedly connected to the outer side of the rotating rod. The locking rods are located inside the annular groove. The attraction between the second phase magnet and the first phase magnet provides a basic fixing force for the mounting base, while the locking rods embedded in the annular groove can limit the rotating rod radially, preventing the mounting base from shaking or falling off during equipment operation. The double fixing structure not only ensures the stability of the mounting base connection, but also simplifies the installation and disassembly operation steps, making it convenient for staff to quickly complete the maintenance and replacement of the mounting base and filter plate.

[0014] This utility model provides a wall-mounted fresh air device, which has the following beneficial effects: 1. This wall-mounted fresh air system significantly improves the convenience and efficiency of filter plate maintenance through a quick-release mechanism. With the help of a combination of screw connection, magnetic attraction and lever limiting structure, the filter plate can be quickly separated from the mounting base. Disassembly can be completed without complicated tools, greatly shortening maintenance time and reducing the difficulty of operation for staff.

[0015] 2. This wall-mounted fresh air system effectively prevents filter plate clogging and maintains a stable filtration effect through its cleaning mechanism. Driven by a waterproof motor, the gear drive rod rotates the gear driven rod, thereby enabling the cleaning brush to clean the filter plate and dust baffle in real time, promptly removing impurities attached to the surface, avoiding the tediousness of manual cleaning and reducing human intervention.

[0017] This utility model embodiment provides a wall-mounted fresh air device.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The device includes a housing 1, an air inlet pipe 101 fixedly connected to the bottom of the housing 1, two dust exhaust pipes 102 fixedly connected to the bottom of the housing 1, three dust baffles 103 fixedly connected to the bottom of the inner cavity of the housing 1, an air pump 2 fixedly connected to the inner cavity of the housing 1, an exhaust pipe 201 fixedly connected to the bottom of the air pump 2, the bottom end of the exhaust pipe 201 extending to the bottom of the housing 1, and a mounting base 3 provided on the top of the housing 1.

[0019] Please refer to it again. Figure 1 and Figure 2 The bottom of the mounting base 3 is screwed with three filter plates 301. The bottom of the filter plates 301 extends into the inner cavity of the housing 1, and the filter plates 301 are in contact with the dust baffle 103. The inner cavity of the housing 1 is fixedly connected to a transmission chamber 4. The inner cavity of the transmission chamber 4 is rotatably connected to a gear driven rod 401. One end of the gear driven rod 401 passes through the transmission chamber 4 and extends to one side of the outermost filter plate 301. Three sets of cleaning brushes 402 are fixedly connected to the outer side of the gear driven rod 401. The cleaning brushes 402 are in contact with the filter plates 301 and the dust baffle 103. The top of the housing 1 is fixedly connected to a waterproof motor 5. The bottom end of the power output shaft of the waterproof motor 5 is fixedly connected to a gear drive rod 501. The bottom end of the gear drive rod 501 passes through the housing 1 and the transmission chamber 4 and extends into the inner cavity of the transmission chamber 4. The bottom end of the gear drive rod 501 is meshed with the gear driven rod 401.

[0020] The quick-release mechanism combines magnetic pre-positioning with rotary locking to enable rapid assembly and disassembly of the filter plate 301 assembly. When disassembly is required, rotating the rotating rod 701 disengages the locking rod 703 from the limiting area of ​​the annular groove 602. Then, pulling the mounting base 3 upwards overcomes the magnetic pre-tightening force, allowing the mounting base 3 and filter plate 301 to be removed as a whole. During installation, the filter plate 301 is aligned with the dust baffle 103 and inserted into the housing 1. The rotating rod 701 passes through the through groove 603 into the docking chamber 6. The attraction force between the second-phase magnet 702 and the first-phase magnet 601 guides the locking rod 703 to align with the opening of the annular groove 602. Rotating to the locking position completes the mechanical fixation. This design simplifies the multi-step operation of traditional bolted connections to a two-step "lift-rotate" action, reducing disassembly time from approximately 5 minutes to less than 30 seconds. Simultaneously, the magnetic pre-tightening force effectively prevents loosening caused by equipment vibration.

[0021] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4Both sides of the housing 1 are fixedly connected to docking chambers 6. The bottom of the inner cavity of the docking chamber 6 is fixedly connected to a first phase magnet 601. The inner cavity of the docking chamber 6 is provided with an annular groove 602 and the top of the docking chamber 6 is provided with a through groove 603. Both sides of the mounting base 3 are fixedly connected to mounting plates 7. The inner side of the mounting plate 7 is rotatably connected to a rotating rod 701. The bottom end of the rotating rod 701 extends into the inner cavity of the docking chamber 6 through the through groove 603, and the bottom end of the rotating rod 701 is fixedly connected to a second phase magnet 702. The second phase magnet 702 is attracted to the first phase magnet 601. Two locking rods 703 are fixedly connected to the outer side of the rotating rod 701. The locking rods 703 are located inside the annular groove 602.

[0022] The cleaning mechanism achieves automatic dust removal through a gear transmission system driven by a waterproof motor 5. The waterproof motor 5 drives the gear drive rod 501 to rotate, and after the direction is changed by the bevel gear pair, it drives the driven rod 401, causing the three sets of cleaning brushes 402 to rotate synchronously. The angled nylon bristles of the cleaning brushes 402 adhere to the pleated filter surface of the filter plate 301 and the surface of the dust baffle 103 with a pre-compression amount of 0.5-1mm, and peel off the intercepted dust and impurities during rotation. Part of the peeled dust falls into the dust discharge pipe 102 along the dust baffle 103, and the other part is discharged through the exhaust pipe 201 by the air pump 2 through the air discharge pipe 201 due to airflow disturbance. The waterproof motor 5 is equipped with a waterproof housing to adapt to humid environments, ensuring stable operation of the cleaning mechanism under harsh working conditions, and extending the clogging cycle of the filter plate 301 from the traditional design of 7 days to more than 15 days.

[0023] Working principle: The quick-release mechanism uses a combination of magnetic pre-positioning and rotary locking to achieve rapid installation and removal of the filter components. When disassembly is required, rotating the rotating rod 701 causes the locking rod 703 to disengage from the limiting area of ​​the annular groove 602. Then, the mounting base 3 is pulled upward to overcome the magnetic pre-tightening force, allowing the mounting base 3 and the filter plate 301 to be removed as a whole. During installation, the filter plate 301 is aligned with the dust baffle 103 and inserted into the housing 1. The rotating rod 701 enters the docking chamber 6 through the through groove 603. The attraction force between the second phase magnet 702 and the first phase magnet 601 guides the locking rod 703 to align with the groove opening of the annular groove 602. After rotating to the locking position, mechanical fixation is completed. This design simplifies the multi-step operation of traditional bolted connections to a two-step action of lifting and turning, reducing the disassembly time from about 5 minutes to less than 30 seconds. At the same time, the magnetic pre-tightening force effectively prevents loosening caused by equipment vibration. The cleaning mechanism achieves automatic dust removal through a gear transmission system driven by a waterproof motor 5. The waterproof motor 5 drives the gear drive rod 501 to rotate, and after the direction is changed by the bevel gear pair, it drives the driven rod 401, causing the three sets of cleaning brushes 402 to rotate synchronously. The angled nylon bristles of the cleaning brushes 402 adhere to the pleated filter surface of the filter plate 301 and the surface of the dust baffle 103 with a pre-compression amount of 0.5-1mm, and peel off the intercepted dust and impurities during rotation. Part of the peeled dust falls into the dust discharge pipe 102 along the dust baffle 103, and the other part is discharged by the air pump 2 through the exhaust pipe 201 through the airflow disturbance. The waterproof motor 5 is equipped with a waterproof shell to adapt to the humid environment, ensuring stable operation of the cleaning mechanism under harsh working conditions. The clogging cycle of the filter plate 301 is extended from the traditional design of 7 days to more than 15 days, and the filter plate 301 can effectively prevent the generation of condensation in the ring mesh box.
