Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically to a fresh air device with air filtration function. Background Technology

[0002] A fresh air system is an air purification device that is commonly used in modern home and office renovations. It circulates indoor air, exchanges indoor air with outdoor air, and effectively improves indoor air quality.

[0003] When an outdoor air is supplied indoors using a fresh air system, it only provides a basic filtration effect, posing a risk of introducing bacteria. Furthermore, cleaning or replacing the filter requires disassembling the device, which is inconvenient. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a fresh air device with air filtration function. The technical solution adopted includes activated carbon bags, mounting boxes, air outlet pipes, air inlet pipes, exhaust inlets, exhaust fans, air supply pipes, ultraviolet lamp power supply equipment, air outlet chambers, pull-out racks, exhaust fans, outer sealing plates, and handles. All of the above components are common prior art. The exhaust fan is powered by an external power source. The remaining parts also include vertical partitions, horizontal partitions, upper disinfection chambers, ultraviolet lamp columns, inner placement frames, bottom seals of placement frames, inner filter frames, outer filter frames, outer rings, and inner... The ring and ring body lifting mechanism have an air inlet pipe on the front of the top of the mounting box and an air outlet pipe on the rear. The exhaust inlet and exhaust fan are located on the rear and front sides of the right side, respectively. An air supply pipe is located to the right of the exhaust fan. A UV lamp power supply device is installed on the right side of the mounting box. A vertical partition is fixed inside the mounting box, with an air outlet cavity behind it, connected to the exhaust inlet. A pull-out bracket is inserted into the air outlet cavity from the rear of the mounting box. An exhaust fan is installed on the pull-out bracket. An integrally formed outer sealing plate is installed on the portion of the pull-out bracket outside the mounting box. A handle is fixed to the side of the outer sealing plate. The exhaust fan can be powered by batteries or attached to the outer sealing plate. An electrical interface is provided on the panel, and a circuit is installed on the pull-out rack to allow the exhaust fan to be powered externally. A horizontal partition is fixed inside the cavity on the front side of the vertical partition. Above the horizontal partition is the upper disinfection chamber, in which ultraviolet lamps are evenly distributed. The upper disinfection chamber is connected to the air inlet duct, and the ultraviolet lamps provide a certain degree of sterilization when outside air enters. The horizontal partition has a central through-hole, and the inner layer placement frame, inner layer filter frame, and outer layer filter frame are fixed concentrically from the inside out on the lower surface of the horizontal partition and the central through-hole. Several activated carbon bags are placed inside the inner layer placement frame, and the bottom of the inner layer placement frame is... The bottom of the placement frame is sealed. The bottom of the inner and outer filter frames is sealed by inner and outer rings, respectively. The inner and outer rings are installed by a ring lifting mechanism set outside the installation box. The ring lifting mechanism is operated externally to drive the inner and outer rings upward, so that the inner and outer rings, which are in close contact with the side walls of the inner and outer filter frames, can clean the side walls of the inner and outer filter frames. The bottom of the installation box can also be made removable, so that the bottom of the installation box can be opened periodically to clean the residue on the inner and outer rings, or the bottom seal of the placement frame can be removed to replace the activated carbon pack.

[0005] As a preferred technical solution of this utility model, the ultraviolet lamp columns are distributed in a matrix, and both the outer and inner rings have annular grooves.

[0006] As a preferred embodiment of this utility model, the ring lifting mechanism includes a pull rope, an outer box, an outer box plug, an inner mounting plate, a rotating shaft, a knob, and a locking part. The inner filter frame, the outer filter frame, and the left side wall of the mounting box all have corresponding through holes, which communicate with the outer box fixed outside the mounting box. The left opening of the outer box is closed by the outer box plug. The outer box has a horizontally fixed inner mounting plate. A rotating shaft is rotatably mounted on the inner mounting plate, driven by a knob below the inner mounting plate. The knob is locked by the locking part. One end of the pull rope is fixed to the rotating shaft, and the other end... It has a forked end, one end of which extends through the through hole to the area between the inner and outer filter frames and connects to the outer ring. The other forked end extends through the through hole to the area between the outer filter frame and the inner placement frame and connects to the inner ring. By operating the knob, the rotating shaft is turned, which pulls the pull rope, allowing the inner and outer rings to move up and down to clean the side walls of the inner and outer filter frames. The inner and outer rings are made of metal and are heavy, so the gravity is greater than the friction of the side walls. After releasing the pull rope, the inner and outer rings can naturally descend and fall back down.

[0007] As a preferred technical solution of this utility model, both the bottom seal of the placement frame and the outer box seal are detachable.

[0008] As a preferred technical solution of this utility model, the locking part includes a knob through hole, a threaded hole and a screw. Several knob through holes are distributed at the outer edge of the knob in the up and down direction. A through threaded hole is opened on the mounting plate inside the box. After the screw is fitted with the threaded hole, the lower end is inserted into the knob through hole to lock the knob.

[0009] The beneficial effects of this utility model are as follows: By setting up a disinfection chamber inside the installation box and installing several ultraviolet lamp columns inside, a certain sterilization effect is provided when air enters. The activated carbon pack placed in the inner placement frame provides further adsorption. The inner and outer filter frames provide further filtration. After a period of use, the outer box seal can be removed from the outside of the installation box, and the knob can be operated to drive the ring lifting mechanism to move the outer and inner rings upward, thereby cleaning the side walls of the inner and outer filter frames.
