Description

Technical Field

[0001] This utility model relates to the technical field of ventilation devices, and in particular to a ventilation device with a filtration function. Background Technology

[0002] With the development of industrialization and urbanization, indoor and outdoor air quality problems have become increasingly prominent. In order to improve indoor air quality, ventilation devices such as exhaust fans and fresh air systems are widely used.

[0003] Existing ventilation devices with filtration functions, such as the ventilation device with air filtration function disclosed in utility model patent application number 202022405834.4, mainly include a fixed back plate and a fixed front plate. The fixed back plate has a threaded hole on the outer side and a threaded nail on the inner side of the threaded hole. The ventilation body is fixed on the outer side of the fixed back plate, and the ventilation chamber is formed on the inner side of the ventilation body. In use, the motor is started to drive the fan blades to rotate. The fan blades drive the air from the ventilation chamber into the filter layer, the filter layer filters the air, and the filtered air enters the room.

[0004] However, most existing ventilation devices use single-layer filtration, which has poor filtration effect and cannot effectively remove various pollutants in the air. Moreover, most existing filter components are inconvenient to disassemble and clean, resulting in high maintenance costs. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a ventilation device with filtration function that not only uses a filter screen and activated carbon to perform dual filtration of air, ensuring the filtration effect, but also facilitates the cleaning and replacement of the filter components, reducing maintenance costs.

[0006] This utility model discloses a ventilation device with filtration function, including an air extraction mechanism; it also includes a telescopic mechanism, a cleaning mechanism, a detection mechanism, and a filtering mechanism. The telescopic mechanism is installed on the air extraction mechanism to easily adapt to walls of different thicknesses. The cleaning mechanism is installed on the telescopic mechanism to clean it. The detection mechanism is installed on the air extraction mechanism to detect the weight of the filtering mechanism. The filtering mechanism is installed on the detection mechanism to perform secondary filtration of the air. The telescopic mechanism is fixed to the exterior wall, and the air extraction mechanism is inserted into a pre-drilled mounting hole in the wall. Then, the detection mechanism is connected and installed to the air extraction mechanism. The filtering mechanism is inserted into the detection mechanism, and the air extraction mechanism is activated to extract air. Outside air is initially filtered by the telescopic mechanism and then enters the filtering mechanism for secondary filtration. After secondary filtration, the air enters the room. The cleaning mechanism is periodically activated to clean the telescopic mechanism. The filtering mechanism becomes heavier after filtering the air, and the detection mechanism detects its weight. When the weight exceeds a preset value, it reminds the staff to replace the filtering mechanism to ensure the filtration effect of the device.

[0007] Preferably, the air extraction mechanism includes a sleeve, a support plate, and an exhaust fan. The sleeve is installed in a pre-drilled mounting hole in the wall, the support plate is installed inside the sleeve, and the exhaust fan is installed on the support plate. When the exhaust fan is activated, outdoor air enters the room through the sleeve.

[0008] Preferably, the telescopic mechanism includes a telescopic sleeve, a fixing ring, and a filter screen. The telescopic sleeve is connected to the inside of the sleeve, the fixing ring is installed on the telescopic sleeve, and four sets of positioning holes are opened on the fixing ring. The filter screen is installed on the fixing ring. The operator uses bolts to fix the fixing ring to the outdoor wall. The telescopic sleeve can be used to adapt to walls of different thicknesses. Outside air enters the sleeve through the filter screen, and the filter screen filters out large particulate impurities in the air.

[0009] Preferably, the cleaning mechanism includes a rainproof box, a motor, a cleaning brush, and a waterproof sleeve. The rainproof box is installed on a fixing ring, the motor is installed inside the rainproof box, the cleaning brush is connected to the output shaft of the motor, and the waterproof sleeve is connected and installed on the cleaning brush and the rainproof box. By setting up the rainproof box and the waterproof sleeve, rainwater is prevented from entering, ensuring the normal operation of the motor. The motor drives the cleaning brush to rotate and clean the filter screen.

[0010] Preferably, the cleaning brush is made of silicone. Silicone can effectively remove dust while having almost zero risk of scratching any type of filter. Moreover, silicone has excellent weather resistance, is stable against ultraviolet light, and is not prone to aging or embrittlement when used outdoors for a long time.

[0011] Preferably, the detection mechanism includes a fixed box, four sets of fixed plates, a weight sensor, a controller, and an alarm. The fixed box is connected to the inside of the sleeve. The fixed box has multiple ventilation holes. All four sets of fixed plates are installed on the fixed box. The weight sensor is installed inside the fixed box. The controller is installed on the fixed box. The alarm is installed on the controller. The operator uses bolts to fix the four sets of fixed plates to the indoor wall. The air in the sleeve enters the fixed box and is filtered a second time by the filtration mechanism. The weight sensor detects the weight of the filtration mechanism. When the weight sensor detects that the weight of the filtration mechanism exceeds a preset value, the controller triggers the alarm to remind the operator to replace the filtration mechanism.

[0012] Preferably, the filtration mechanism includes a filter drawer, a handle, and a sealing ring. The filter drawer is slidably installed in a fixed box and contains filter media. The handle and the sealing ring are installed on the filter drawer. The filter media in the filter drawer filters the air to ensure the filtration effect. The sealing ring ensures the sealing effect. The operator operates the handle to pull out the filter drawer and replace the filter media.

[0013] Preferably, the filling material inside the filter drawer is activated carbon; activated carbon has a strong physical adsorption capacity, which can effectively adsorb harmful substances in the air, and has a wide adsorption range, effectively adsorbing a variety of harmful substances.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the telescopic mechanism is fixed on the exterior wall and the air extraction mechanism is inserted into the pre-drilled installation hole on the wall. Then, the detection mechanism is connected and installed with the air extraction mechanism, the filter mechanism is inserted into the detection mechanism, and the air extraction mechanism is started to extract air. The outside air is initially filtered by the telescopic mechanism and then enters the filter mechanism for secondary filtration. After secondary filtration, the air enters the room. The cleaning mechanism is turned on regularly to clean the telescopic mechanism. The filter mechanism will become heavier after filtering the air. The detection mechanism detects its weight. When the weight exceeds the preset value, it reminds the staff to replace the filter mechanism to ensure the filtration effect of the device. Attached Figure Description
