Description

Technical Field

[0001] This invention belongs to the field of oil fume purification technology, specifically referring to a pressure-sensitive control-based oil fume purification device for residential buildings and its usage method. Background Technology

[0002] Most modern high-rise residential buildings are designed with a continuous flue system, where each household connects its range hood to the flue. The cooking fumes are then centrally discharged through exhaust vents located on the roof. This centralized design makes it possible to purify the cooking fumes emitted from high-rise residential buildings before discharging them, greatly reducing environmental pollution. However, the emission of cooking fumes is generally concentrated during cooking time, with very little or no emission at other times. Running the purification equipment all day would undoubtedly increase power consumption and shorten the equipment's lifespan. If it is only turned on during designated time periods, the experience for residents using it at other times would be unpleasant. Therefore, the most reasonable solution is to detect whether cooking fumes are passing through, thereby controlling the opening and closing of the purification equipment. Summary of the Invention

[0003] In response to the above situation and to overcome the shortcomings of the existing technology, the present invention provides a pressure-sensitive control-based residential building fume purification device and its usage method. The gravity-driven opening and closing device ensures that the air containing fumes can only flow in one direction, preventing pressure loss. The piston, driven by pressure, compresses the spring through the connecting rod and the slider, thus touching the switch. At this time, the purifier starts to work, effectively solving the problem of the difficulty in determining the start-up time of centralized purifiers in high-rise residential buildings on the market.

[0004] The technical solution adopted by this invention is as follows: This invention provides a pressure-sensitive control-based residential building oil fume purification device, comprising an opening and closing device, a lifting touch control device, a pressure-driven sliding device, an oil fume purification device, and a main frame.

[0006] Furthermore, the pressure-driven sliding device includes a sliding piston, a telescopic sleeve, and a telescopic rod. The sliding piston is mounted on the fume purification device, the connecting rod shaft is mounted on the sliding piston, the telescopic sleeve is mounted on the fume purification device, and the telescopic rod is mounted on the sliding piston. The telescopic rod is engaged and slidably mounted in the telescopic sleeve.

[0007] Furthermore, the fume purification device includes a purifier, an exhaust duct, an induced draft fan, and a control box. The purifier is mounted on the main frame, the exhaust duct is mounted on the purifier, the induced draft fan is mounted on the exhaust duct, the control box is mounted on the main frame, the fixed door frame is fitted into the control box, the hoisting base is mounted on the control box, the sliding piston is fitted into the control box, the telescopic sleeve is mounted on the control box, the control box has a circular hole, and the exhaust duct is fitted into the circular hole.

[0009] The present invention discloses a method for using a pressure-sensitive controlled kitchen fume purification device for residential buildings, characterized by comprising the following steps:

[0010] Step 1: When a resident uses a range hood, the range hood in the resident's home exhausts the air containing oil fumes into the air duct, increasing the air pressure in the air duct. The flowing air blows open the door and into the control box.

[0011] Step 2: As the incoming air and air pressure increase, the sliding piston slides under the push of the air, and pushes the sliding block upward along the spring mounting axis through the long connecting rod;

[0012] Step 3: When the slider boss contacts the touch switch, the purifier and the exhaust fan start.

The gravity-driven opening and closing device ensures that the air containing oil fumes can only flow in one direction, preventing pressure loss. The piston, driven by pressure, compresses the spring through the connecting rod and the slider, thus touching the switch. At this time, the purifier starts to work, effectively solving the problem that the start-up time of centralized purifiers in high-rise residential buildings on the market is difficult to determine.
