Description

Technical Field

[0001] This utility model relates to the field of ventilation and filtration technology, specifically a filtration structure for a ventilation device. Background Technology

[0002] Traditional ventilation filtration devices consist of two parts: a fan filter unit and a high-efficiency filter unit located below the fan filter unit. Traditional high-efficiency filters are fixed in place by the gravity of the fan filter unit during installation.

[0003] As disclosed in CN 219231789 U, a filter structure for a computer room ventilation system includes a housing. The housing has a connection port on its surface. A ventilation box is fixedly connected to the inner wall of the connection port. From left to right, a primary dustproof net, a secondary dustproof net, and a support frame are fixedly connected to the inner wall of the ventilation box. A fan is fixedly connected to the inner wall of the support frame. This invention not only intercepts dust twice through the primary and secondary dustproof nets but also provides some rain protection. Through the coordinated use of a rotating shaft, a fixing block, a connecting block, and a brush, the fan drives the fan blades to rotate, simultaneously driving the rotating shaft, which in turn drives the brush to rotate. This causes the brush to rotate periodically, cleaning the dust on the surfaces of the primary and secondary dustproof nets, thus achieving automatic cleaning of dust accumulated on the filter screen.

[0004] However, the existing technology CN 219231789 U describes a filter structure for a ventilation device in a computer room. This device does not have a convenient locking and disassembly mechanism and does not use a tenon and mortise connection method. It is relatively troublesome for staff to disassemble and install it, and long-term lack of replacement and cleaning will affect the filtration effect of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a filter structure for ventilation equipment to solve the problems of the above-mentioned devices not having a convenient locking and disassembly mechanism, not using mortise and tenon joints, making disassembly and installation troublesome for workers, and affecting the filtration effect of the device if it is not replaced and cleaned for a long time.

[0006] To achieve the above objectives, this utility model provides a filter structure for a ventilation device.

[0007] The device includes a fixed box with ventilation slots inside. A locking filter mechanism is movably mounted on both sides of the fixed box. The locking filter mechanism includes a limiting slot, a through slot, a fixing hole, a fixing strip, a fixing frame, fixing posts, and a filter screen. The fixed box has limiting slots on both sides inside and through slots on both sides outside. Fixing holes are located on both sides at the bottom of the through slots. A fixing strip is movably mounted inside the limiting slot. A fixing frame is fixedly mounted on the side of the fixing strip. Fixing posts are fixedly mounted on both sides at the bottom of the fixing frame, and the fixing posts are movably connected to the fixing holes. A filter screen is fixedly mounted inside the fixing frame. An installation block is fixedly mounted on one side of the top of the fixing frame, and a movable post is movably mounted inside the installation block.

[0008] The fixed box has connecting blocks fixedly installed on both sides of its top. The connecting blocks have placement slots inside. When the handle is not needed, the handle can be installed and hidden inside the placement slots.

[0009] The movable column is equipped with a handle on its side, one end of which is movably connected to the placement slot. The handle design allows staff to easily remove the fixed frame and its internal filter screen for replacement and cleaning.

[0010] An air inlet pipe is fixedly installed on one side of the fixed box, and an air outlet pipe is fixedly installed on the other side of the fixed box. Air enters through the air inlet pipe, passes through the filter screen on one side of the fixed box and is then passed into the fixed box. It is then filtered a second time by the filter screen on the other side of the fixed box and finally discharged through the air outlet pipe.

[0011] The air inlet pipe and the air outlet pipe are provided with flow grooves inside, which facilitates the free flow of air inside the pipe.

[0012] The air inlet pipe and the air outlet pipe are fixedly installed on both sides of the outside of the fixed block. The fixed block is equipped with a positioning screw. The operator can rotate the positioning screw to pass through the fixed block and move it to the inside of the fixed box, so as to stably fix the air inlet pipe and the air outlet pipe to the sides of the fixed box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The filter structure of this ventilation equipment allows the operator to rotate the positioning screws to pass through the fixing block and connect them to the inside of the fixing box on both sides, thereby stably fixing the air inlet pipe and the air outlet pipe to both sides of the fixing box. Air enters through the air inlet pipe, passes through the filter screen on one side of the fixing box, is transmitted to the inside of the fixing box, is then filtered a second time by the filter screen on the other side of the fixing box, and is finally discharged through the air outlet pipe. After long-term use, the filter screen needs to be cleaned and replaced. The operator can manually rotate the movable column to remove the handle from the placement groove inside the connecting block and pull it out to remove the fixing frame from the inside of the fixing box. Since the fixing strips on both sides of the fixing frame are engaged with the limiting slots on both sides of the fixing box, and the fixing column at the bottom of the fixing frame is engaged with the fixing hole at the bottom of the through groove, the operator only needs to apply a little force to remove it for cleaning and replacement.

[0015] 2. The filter structure of this ventilation equipment has a convenient snap-fit ​​and disassembly mechanism. The filter screen can be easily disassembled for cleaning and replacement by the mortise and tenon connection, which ensures the filtration effect of the equipment. At the same time, its fixing method is also more stable. The handle set at the top of the fixing frame makes it easy for the staff to remove the filter screen with ease. Attached Figure Description
