Description

Technical Field

[0001] The utility model belongs to the technical field of building ventilation and air exchange, and in particular relates to a building ventilation and air exchange device. Background Art

[0002] Building ventilation usually replenishes fresh air from outside the building into the indoor space and squeezes out the dirty air inside the building to the outside, so as to keep the indoor air environment in line with the hygiene standards. In order to purify the air entering from the outside, the existing technology often sets a filter plate in the ventilation device. After long-term use, the filter plate will be contaminated with pollutants, resulting in reduced ventilation efficiency, and needs to be replaced manually regularly.

[0003] A Chinese patent with publication number CN117704548A discloses an energy-saving ventilation device for green buildings. The solution includes a ventilation duct, a motor is fixedly arranged above the ventilation duct, a filter plate and a screw are arranged in the ventilation duct, and a cleaning component is arranged outside the screw. The above solution uses motor 1 to drive the screw to rotate, thereby driving the cleaning component to move up and down, so as to clean the filter plate.

[0004] The above solution cleans the filter plate by moving the cleaning component, reducing the frequency of manual replacement of the filter plate, ensuring ventilation efficiency while saving human resources. However, during use, the cleaning component can only move in one direction relative to the filter plate, resulting in poor cleaning effect on the filter plate. Utility Model Content

[0005] The utility model aims to provide a building ventilation device to solve the problem of poor cleaning effect on the filter plate in the above solution.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A building ventilation device comprises a ventilation duct, a cleaning brush and a filter plate, wherein a fan is fixedly arranged on the left side of the inner cavity of the ventilation duct, a screw is rotatably inserted on the right side of the fan in the ventilation duct, an installation cavity is arranged above the ventilation duct, a motor is fixedly arranged in the installation cavity, the motor is transmission-connected to the screw, the cleaning brush is fitted on the screw, the filter plate is vertically arranged in the ventilation duct, and the filter plate and the cleaning brush are slidingly abutted, the filter plate is transmission-connected to the motor through a transmission mechanism, and the transmission mechanism is used to drive the filter plate to move back and forth.

[0008] The principle and effect of this technical solution:

[0009] When the filter plate needs to be cleaned, the motor is driven to drive the screw to rotate, thereby driving the cleaning brush to move vertically up and down, and clean the filter plate vertically. At the same time, the motor drives the filter plate to reciprocate in the front and rear directions through the transmission mechanism, so that the cleaning brush cleans the filter plate horizontally.

[0010] Through the above arrangement, the cleaning brush can move relative to the filter plate in the horizontal and vertical directions at the same time and clean it, thereby reducing the frequency of replacing the filter plate and improving the cleaning effect, thus solving the problem of poor cleaning effect on the filter plate in the above solution.

[0011] In the utility model, the transmission mechanism includes a transmission shaft, a connecting rod and a mounting frame. The transmission shaft is rotatably arranged in the mounting cavity, and one end of the transmission shaft is transmission-connected with the output end of the motor, and the other end of the transmission shaft is fixedly sleeved with a disc, and a round pin is eccentrically arranged on the side wall of the disc, and a protrusion is fixedly arranged on the top of the mounting frame, one end of the connecting rod is rotatably connected with the round pin, and the other end is rotatably connected with the protrusion, and the front and rear sides of the inner cavity of the ventilation pipe are respectively provided with slide grooves, and the front and rear ends of the mounting frame are respectively slidably embedded in the slide grooves, and the mounting frame has a left-right through air duct, and the filter plate is slidably inserted in the mounting frame, and a locking mechanism is arranged on the front wall of the mounting frame. Through the above arrangement, the purpose of making the filter plate reciprocate in the front and rear directions is achieved.

[0012] In the present invention, the top and bottom of the installation frame are respectively slidably abutted against the inner wall of the ventilation pipe, the bottom of the installation cavity is provided with a through slot that penetrates the inner cavity of the ventilation pipe, the protrusion is slidably arranged in the through slot, and the width of the through slot is equal to the width of the protrusion and smaller than the width of the installation frame. Through the above arrangement, it is possible to prevent unfiltered air from flowing from the installation cavity into the room, thereby ensuring the purification effect of the present invention on outdoor air.

[0013] In the utility model, the locking mechanism comprises a groove recessed in the side wall of the installation frame, a baffle embedded in the groove, and a bolt slidably penetrated through the baffle and threadedly inserted into the installation frame.

[0014] In the utility model, an opening is formed on the side wall of the slide groove at the front side, and a movable door is rotatably connected to the opening.

[0015] The principle and effect of this technical solution:

[0016] When the filter plate needs to be replaced, open the movable door and rotate the bolts to disengage the bolts from the mounting frame and the baffle, then remove the baffle and the filter plate, and then slide the new filter plate into the mounting frame, and then embed the baffle into the groove. At this time, the baffle and the filter plate are in contact, and the bolts are slid through the baffle and threaded into the mounting frame, and finally the movable door is closed.

[0017] The above arrangement can facilitate the replacement of the filter plate by the staff, and can also limit the displacement of the filter plate relative to the installation frame during the reciprocating movement of the installation frame, thereby improving the cleaning effect.

[0020] In the utility model, the right end of the shield is magnetically connected to the slide rail.

[0021] The principle and effect of this technical solution:

[0022] When the filter plate needs to be cleaned, turn off the fan and slide the shield outward at the same time to connect the interior of the collection box with the interior of the ventilation pipe through the collection port, start the motor to drive the cleaning brush to sweep off the attachments on the filter plate. After the attachments fall into the collection box due to gravity, turn off the motor, pass the shield through the slide rail on the right side and slide it onto the top of the collection box, and connect the right end of the shield to the slide rail through magnetic attraction.

[0023] Through the above arrangement, fallen attachments can be collected during cleaning work, and at the same time, the collection box can be shielded when the fan is working to prevent the attachments in the box from flying out, thereby improving the cleaning effect.

[0024] In the utility model, the outer fixed sleeve of the transmission shaft is provided with a first bevel gear, the top fixed sleeve of the screw rod is provided with a second bevel gear, and the first bevel gear meshes with the second bevel gear. Through the above arrangement, the purpose of rotating the screw rod is achieved. BRIEF DESCRIPTION OF THE DRAWINGS
