Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a filter-side replaceable high-efficiency air outlet. Background Technology

[0002] A filter is a device used to separate impurities or specific substances from a fluid. Its core function is to use physical, chemical, or biological methods to allow the fluid to pass through a filter medium with a certain pore size or selectivity, intercepting or adsorbing solid particles, colloids, microorganisms, pigments, odor components, etc., thereby achieving the purpose of purifying, refining, separating, or concentrating the fluid. Side-replaceable high-efficiency air outlets are terminal devices in cleanroom purification systems that combine high-efficiency filtration with convenient maintenance. Their core advantage lies in the ability to quickly replace the high-efficiency filter through the side inspection port without disassembling the entire frame, significantly reducing cleanroom downtime.

[0003] As the device operates, dust and other impurities continuously accumulate on the filter screen, gradually clogging the pores over time. This significantly increases airflow resistance. Accumulated dust may penetrate the filter screen with the airflow and adhere to the surface of the baffle plate, especially in the blade gaps or corners, creating dust accumulation dead zones. This not only affects the baffle plate's airflow guidance accuracy but can also become a breeding ground for microorganisms. Furthermore, during device maintenance, the rigidly fixed baffle plate hinders the removal and installation of the HEPA filter through the side inspection port. Replacing the filter requires disassembling the entire air outlet frame, and frequent disassembly and reassembly can compromise the structural seal, increasing the risk of air leakage. Therefore, a filter-side-replaceable HEPA air outlet is proposed to address these issues. Utility Model Content

[0006] The cleaning assembly includes a cylinder, a slider fixedly connected to the output end of the cylinder, a rotating rod rotatably connected to the top of the slider, cleaning brushes fixedly connected to both sides of the top of the rotating rod, a gear fixedly connected to the outer side of the rotating rod, a fixed rod rotatably connected to the bottom of the gear, slide rails slidably connected to both sides of the slider, a rack fixedly connected to the outer side of one of the slide rails, a dust cover fixedly connected to the outer side of the housing away from the cylinder, a fan fixedly connected inside the dust cover, a dustproof plate fixedly connected inside the dust cover, and a dust collection bag provided at the bottom of the dust cover.

[0007] As a further description of the above technical solution:

[0008] The fixing component includes a protective shell, which is fixedly connected to the outside of the housing. A support block is slidably connected inside the protective shell. A limit rod is fixedly connected to one side of the support block, a connecting rod is fixedly connected to the other side of the support block, and a spring is fixedly connected to the other side of the support block.

[0009] As a further description of the above technical solution:

[0010] The connecting rod is slidably connected inside the protective shell, and the side of the spring away from the support block is fixedly connected inside the protective shell.

[0011] As a further description of the above technical solution:

[0012] The limiting rod is slidably connected inside the protective shell, and the limiting rod is slidably connected inside the guide plate.

[0013] As a further description of the above technical solution:

[0014] The slide rail is fixedly connected to the bottom of one of the support frames, and the cleaning brush and the filter screen abut against each other.

[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] The cylinder is fixedly connected inside the housing, and the filter screen is disposed inside the housing.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the air outlet is running, the filter screen accumulates dust and the guide plate is dusty, which reduces the ventilation efficiency of the system. The cylinder is started, and the piston drives the slider to move linearly along the slide rail, which drives the rotating rod and the cleaning brush to sweep laterally. The rotating rod meshes with the gear and rack to convert the linear motion into a compound motion, thereby cleaning the filter screen. After cleaning, the residual dust falls off the filter. The fan is started to form a negative pressure in the box. The dust enters the dust cover through the opening. Using the principle of inertial separation, it is blocked by the dust plate and falls into the dust collection bag, completing the automated cleaning and dust collection. This achieves stable maintenance of the resistance when the airflow passes through the filter screen, maintains the uniformity of the airflow pressure at the front end of the guide plate, and effectively reduces the risk of microbial growth and cross-contamination.

[0023] 2. In this utility model, when replacing the filter screen, a linear traction is generated by applying force to the connecting rod. The spring is compressed by the support block, which drives the limiting rod to disengage from the positioning slot of the guide plate, thus releasing the mechanical limit and completing the disassembly. After the replacement is completed, the guide plate and filter screen are reset, the external force on the connecting rod is removed, the spring releases its elastic potential energy, pushes the support block to move in the opposite direction, and drives the limiting rod to embed into the limiting slot, forming a rigid constraint. This enables the guide plate to be installed quickly and stably, completing the entire disassembly and assembly process. This allows for the rapid disassembly of the guide plate without tools, greatly shortening the downtime of the device and reducing production losses. Attached Figure Description

[0041] Working principle:

[0042] During continuous operation of the air outlet, dust particles gradually accumulate on the filter screen 6. Some of these particles settle onto the guide plate 4 due to gravity and airflow disturbance, leading to increased system ventilation resistance and decreased operating efficiency. To ensure device performance, the cylinder 7 is activated, and its piston reciprocates to drive the slider 12 to move linearly along the slide rail 9, which in turn drives the rotating rod 11 and the cleaning brush 10 to complete a lateral sweep. Through the meshing transmission of the gear 13 and the rack 8, the linear motion of the rotating rod 11 is converted into a combined rotational and linear motion, enabling the cleaning brush 10 to clean and effectively remove dust from the filter screen. After cleaning, the residual dust detaches from the filter screen during the return stroke. Based on the principle of negative pressure in fluid mechanics, the fan 16 is activated to create negative pressure inside the housing 1. Under the action of pressure difference, dust particles enter the dust cover 15 through the opening. Utilizing the principle of inertial separation, the dust cover 17 blocks the dust, causing it to fall into the dust collection bag 18 under the action of gravity. This system integrates mechanical transmission and airflow control to achieve automated operation of filter cleaning and dust collection.

[0043] When replacing the filter screen 6, an outward linear traction force is applied to the connecting rod 23, which is transmitted to the support block 20 through the connection, driving it to move along a predetermined trajectory. During the movement, the support block 20 compresses the spring 22 to store elastic potential energy, and at the same time drives the limiting rod 21 to disengage from the positioning slot of the guide plate 4, releasing the mechanical limit and realizing the disassembly of the guide plate 4. After the filter screen 6 is replaced, the installation and reset process of the guide plate 4 begins. After the guide plate 4 and the filter screen 6 are positioned in the initial installation position, the external force on the connecting rod 23 is released. Based on the recovery characteristics of the elastic element, the spring 22 releases the stored elastic potential energy, generating a restoring force acting on the support block 20. This restoring force drives the support block 20 to move in the opposite direction, causing the limiting rod 21 to be precisely embedded in the preset limiting groove of the guide plate 4. Through this mechanical limiting mechanism, a constraint is formed on the guide plate 4, realizing its stable installation. The entire operation process realizes the quick and reliable disassembly and installation of the guide plate 4 through the synergistic effect of the elastic element and the limiting structure.
