Description

Technical Field

[0001] This utility model relates to the field of fresh air equipment technology, specifically to a mechanism for improving the application cycle of a fresh air equipment cleaning device. Background Technology

[0002] As people increasingly value indoor air quality, fresh air systems, as key equipment for improving indoor air quality, have been widely used in various fields. During the operation of a fresh air system, the filtration system is one of the core components, its main function being to filter dust, particulate matter, and other impurities from the air, ensuring the cleanliness of the air entering the room. However, existing fresh air system filtration systems have significant drawbacks during long-term use. Traditional fresh air systems typically rely on a single filter layer for air filtration, allowing a large amount of dust and particulate matter to adhere directly to the filter surface, leading to easy clogging. This not only reduces the ventilation efficiency of the fresh air system but also necessitates frequent cleaning of the filter layer by the cleaning device. Frequent cleaning increases wear and tear on the cleaning device, shortening its service life, and also increases maintenance costs and workload for users. Furthermore, the cleaning device in traditional fresh air systems often suffers from unstable guidance and insufficient support during movement, further exacerbating wear and tear and shortening its lifespan. Therefore, a mechanism to improve the service life of the cleaning device in fresh air systems is proposed. Summary of the Invention

[0003] The purpose of this invention is to solve the above problems by proposing a mechanism to improve the application cycle of the cleaning device for fresh air equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mechanism for improving the application cycle of a cleaning device for a fresh air system, comprising a housing connected to the fresh air system and a filter layer installed inside the housing, characterized in that: it further comprises a primary filter screen disposed on the air inlet side of the housing for pre-filtering the incoming air, a cleaning device disposed between the filter layer and the primary filter screen for cleaning the filter layer, a driving device for driving the cleaning device to reciprocate along the surface of the filter layer, and a composite guide support assembly for supporting and guiding the smooth movement of the cleaning device.

[0005] Preferably, the drive device includes a drive motor disposed within the cleaning device, a gear disposed on the output shaft of the drive motor, and a rack disposed on the housing and meshing with the gear.

[0006] Preferably, the composite guide support assembly includes a sliding support mechanism disposed on the upper part of the cleaning device for providing radial support and a rolling guide mechanism disposed on the bottom of the cleaning device for bearing vertical loads and providing guidance.

[0007] Preferably, the sliding support mechanism includes bearing seats symmetrically arranged on both sides inside the housing, a guide rod mounted between the two bearing seats, a linear bushing sleeved on the guide rod, and a connecting piece connecting the linear bushing sleeve and the cleaning device.

[0008] Preferably, the rolling guide mechanism includes a guide rail fixedly installed at the bottom of the housing, a support base fixedly connected to the bottom of the cleaning device, and a roller mounted to the support base via a bearing and capable of rolling along the guide rail.

[0009] Preferably, sensors are provided on both sides of the housing to sense the limits of the movement position of the cleaning device 4.

[0010] Preferably, the side of the housing is provided with an openable maintenance door.

[0011] Preferably, the primary filter is a metal wire mesh or a perforated stainless steel plate, and is parallel to the filter layer, and is detachably installed on the frame of the housing by means of clips or screws.

[0012] The beneficial effects of this utility model are as follows: By setting up a primary filter, a first barrier is formed, which effectively intercepts large-sized pollutants such as leaves, flying insects, and plastic bags, preventing them from entering the equipment and interfering with, wearing down, or jamming the drive components of the cleaning device. This fundamentally reduces the failure rate of the core moving parts and significantly extends the service life of the entire cleaning device assembly.

[0013] Through the synergistic action of the sliding support mechanism and the rolling guide mechanism, a three-dimensional support system is formed in both radial and vertical dimensions. The sliding support mechanism, through the precise fit between the guide rod and the linear bushing, effectively limits the displacement deviation of the cleaning device in the radial direction, avoiding left and right swaying during operation. The rolling guide mechanism, through the support seat bearing the vertical load, and the stable contact between the roller and the guide rail, prevents the cleaning device from bouncing up and down. This dual protection ensures that the cleaning device always maintains a stable operating posture, ensuring mechanical reliability in long-term reciprocating motion and further extending the life of moving parts.

[0016] The following description, in conjunction with the accompanying drawings, further illustrates the mechanism for improving the application cycle of a fresh air equipment cleaning device according to this utility model.

[0017] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0018] See appendix Figure 1-4 As shown, this embodiment of a mechanism for improving the application cycle of a cleaning device for a fresh air system includes a housing 1 connected to the fresh air system and a filter layer 2 installed inside the housing 1. The mechanism is characterized by further including a primary filter 3 disposed on the air inlet side of the housing 1 for pre-filtering the incoming air, a cleaning device 4 disposed between the filter layer 2 and the primary filter 3 for cleaning the filter layer 2, a driving device 5 for driving the cleaning device 4 to reciprocate along the surface of the filter layer 2, and a composite guide support assembly 6 for supporting and guiding the cleaning device 4 to move smoothly.

[0019] The primary filter 3 forms the first barrier, effectively intercepting large pollutants such as leaves, flying insects, and plastic bags, preventing them from entering the equipment and interfering with, wearing down, or jamming the drive components of the cleaning device 4. This fundamentally reduces the failure rate of the core moving parts and significantly extends the service life of the entire cleaning device 4 assembly.

[0020] Referring to the accompanying drawings, the driving device 5 includes a drive motor 51 disposed within the cleaning device 4, a gear 52 disposed on the output shaft of the drive motor 51, and a rack 530 disposed on the housing 1 and meshing with the gear 52. The drive motor 51 is a stepper motor, fixedly installed inside the housing of the cleaning device 4, with its output end penetrating through the top of the housing of the cleaning device 4. The gear 52 is coaxially fixedly mounted on the output end of the drive motor 51, and the tooth pitch of the gear 52 is adapted to the rack 53. The rack 53 is elongated and fixedly disposed on the top of the inner wall of the housing 1, with its length adapted to the height of the filter layer 2, and the tooth surface of the rack 53 faces the gear 52, meshing with the gear 52 for transmission. When the drive motor 51 is started, the gear 52 rotates with the output end, and through meshing with the rack 53, drives the cleaning device 4 to move along the length direction of the rack 53, thereby realizing the movement of the cleaning device 4 along the surface of the filter layer 2.

[0021] See appendix Figure 3-4 As shown, the composite guide support assembly 6 includes a sliding support mechanism 61 disposed on the upper part of the cleaning device 4 for providing radial support and a rolling guide mechanism 62 disposed on the bottom of the cleaning device 4 for bearing vertical loads and providing guidance; the sliding support mechanism 61 includes bearing seats 611 symmetrically disposed on both sides inside the housing 1, a guide rod 612 mounted between the two bearing seats 611, a linear bushing 613 sleeved on the guide rod 612, and a connecting piece 614 connecting the linear bushing 613 and the cleaning device 4; the rolling guide mechanism 62 includes a guide rail 621 fixedly installed on the bottom of the housing 1, a support seat 622 fixedly connected to the bottom of the cleaning device 4, and a roller 623 mounted to the support seat 622 via a bearing and capable of rolling along the guide rail 621.

[0022] There are two bearing seats 611, made of metal, which are symmetrically fixed to the inner walls of both sides of the outer casing 1 by screws. A circular through hole is opened in the center of each bearing seat 611. The guide rod 612 passes through the through hole of the two bearing seats 611 and is fixed to the bearing seats 611 by nuts. The linear bushing 613 is pre-fitted onto the connecting piece 614 and then fitted onto the outer wall of the guide rod 612. One end of the connecting piece 614 is connected to the cleaning device 4 by bolts. When the cleaning device 4 moves under the drive of the drive device 5, the linear bushing 613 slides synchronously along the guide rod 612, and the connecting piece 614 drives the cleaning device 4 to move synchronously. The cooperation of the guide rod 612 and the linear bushing 613 can provide stable radial support for the cleaning device 4 and reduce the swaying of the cleaning device 4 in the radial direction.

[0023] While the cleaning device 4 slides along the guide rod 612, part of the weight of the cleaning device 4 falls on the support 622, and the support 622 bears the vertical load of the cleaning device 4; the rolling cooperation between the roller 623 and the guide rail 621 converts sliding friction into rolling friction, which greatly reduces the frictional resistance of the cleaning device 4 during the movement process, reduces the wear of the cleaning device 4, and ensures that the cleaning device 4 can move smoothly along the fixed trajectory.

[0024] Through the synergistic action of the sliding support mechanism 61 and the rolling guide mechanism 62, a three-dimensional support system is formed in both radial and vertical dimensions. The sliding support mechanism 61, through the precise cooperation between the guide rod 612 and the linear bushing 613, effectively limits the displacement deviation of the cleaning device 4 in the radial direction, avoiding left and right swaying during operation. The rolling guide mechanism 62, through the support seat 622 bearing the vertical load, and in conjunction with the stable contact between the roller 623 and the guide rail 621, prevents the cleaning device 4 from bouncing up and down. This dual protection ensures that the cleaning device 4 always maintains a stable operating posture, ensuring mechanical reliability in long-term reciprocating motion and further extending the life of moving parts.

[0025] See appendix Figure 3-4 As shown, the outer casing 1 is provided with sensors 7 on both sides for sensing the movement limit of the cleaning device 4; when the cleaning device 4 moves to one end of its travel and triggers the sensor 7, the sensor 7 feeds back the signal to the control system, and the control system then commands the drive motor 51 to reverse, thereby realizing the automatic reciprocating motion of the cleaning device 4.

[0026] See appendix Figure 1 , 3 As shown, the side of the outer casing 1 is provided with an openable maintenance door 8; the maintenance door 8 is located on the side of the outer casing 1 and is connected to the outer casing 1 by a hinge. The maintenance door 8 is equipped with a door lock for easy opening and closing by the user. When maintenance is required on components such as the primary filter 3, filter layer 2, and cleaning device 4, the user only needs to unlock the door and open the maintenance door 8 to perform the operation.

[0027] See appendix Figure 1 As shown, the primary filter 3 is a metal wire mesh or a stainless steel perforated plate, and is parallel to the filter layer 2. It is detachably installed on the frame of the outer casing by means of clips or screws. The mesh size of the primary filter 3 is about 2-3mm. It is fixed to the outermost air inlet of the outer casing 1 by means of clips or screws around the perimeter. Its installation position is located upstream of all moving parts inside the equipment, which can effectively block most large particulate pollutants.

[0028] During operation and maintenance, when the fresh air equipment is running normally, outside air first enters the air inlet side of the outer casing 1 and is pre-filtered by the primary filter 3, where large particles of impurities in the air are intercepted. After primary filtration, the air continues to flow to the filter layer 2, where the filter layer 2 further filters the fine impurities in the air. The filtered clean air then enters the fresh air equipment and is delivered to the room by the fresh air equipment. When the cleaning program is started, the fresh air equipment stops running, the vacuuming device of the cleaning device 4 starts working, and the drive device 5 works at the same time. The drive motor 51 starts, driving the gear 52 to rotate on the rack 53, thereby driving the cleaning device 4 to move back and forth along the surface of the filter layer 2 to clean the impurities attached to the surface of the filter layer 2.

[0029] During the movement of the cleaning device 4, the linear bushing 613 of the sliding support mechanism 61 slides along the guide rod 612 to provide radial support for the cleaning device 4; the roller 623 of the rolling guide mechanism 62 rolls along the guide rail 621 to provide vertical support and guidance for the cleaning device 4, ensuring that the cleaning device 4 moves smoothly and reducing wear. When the cleaning device 4 moves to one end of its travel, it triggers the sensor 7 installed on that side. The sensor 7 feeds a signal back to the control system that controls the drive motor 51. The control system then instructs the drive motor 51 to reverse, and the cleaning device 4 changes direction and moves to the other side. When it reaches the limit position on the other side, it is also triggered by the sensor 7 to reverse again. This process is repeated several times or stops after the preset cleaning time is reached. The ventilation resistance of the filter layer 2 is restored, and the fresh air equipment continues to ventilate normally.

[0030] When the primary filter 3 or filter layer 2 needs to be cleaned or replaced, the user can open the maintenance door 8 on the side of the housing 1, remove the primary filter 3 or filter layer 2 using the clips, clean or replace it, and then reinstall it. The operation is convenient.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
