[0034] Example 1

[0035] Figure 1 This is a schematic diagram of an optional air purification system according to an embodiment of this application, such as... Figure 1As shown, it includes:

[0036] An air inlet 11 is located on the garage floor; an exhaust fan 13 and an exhaust duct 12, wherein the exhaust fan is used to discharge vehicle exhaust gas drawn in from the air inlet to the outside through the exhaust duct.

[0037] The spatial structure of the garage is as follows Figure 2 The diagram shows (fresh air inlet 201, exhaust air inlet 202, bidirectional ventilation unit 203, exhaust air outlet duct 204, fresh air outlet 205, road surface 206, grid unit 207, underground exhaust duct 208, pressure generator 209, and underground exhaust fan 210), with a top view as follows. Figure 3 (Grid unit 31 and underground exhaust duct 32 are shown). The above-mentioned garage road surface is a grid-type road surface. The exhaust duct and the exhaust fan are installed under each grid frame of the grid-type road surface. A grille for carrying the car is installed on each grid frame of the grid-type road surface. An air inlet is opened on the grille.

[0038] The above-mentioned exhaust duct can be one or two. If there is one, the exhaust fan can be arranged at the air inlet, the air inlet end of the exhaust fan can be directly connected to the air inlet, and the air outlet can be connected to the exhaust duct. If there are two, one exhaust duct can be connected to the air inlet and the exhaust fan, and the other exhaust duct can be connected to the air outlet and the exhaust fan.

[0039] Optionally, the above system may further include:

[0040] A first air quality detection device is installed below the grid frame and is used to detect vehicle exhaust gas from the air intake.

[0041] The controller, as the control center, is connected to the first air quality detection device and the exhaust fan, etc., and is used to start the exhaust fan when the first air quality detection device detects vehicle exhaust to extract the vehicle exhaust from the garage to the outside.

[0042] A pressure generator is installed below the grille and is connected to the controller, the first air quality monitoring device, and the exhaust fan, respectively. It is used to convert the pressure of a car on the grille into electrical energy to power the first air quality monitoring device and the exhaust fan.

[0043] A two-way ventilation unit is installed on the top of the garage in a suspended manner. The two-way ventilation unit includes a fresh air fan for providing fresh air and an exhaust fan for exhausting air.

[0044] A second air quality detection device is installed at the air inlet of the bidirectional ventilation unit and is used to start the bidirectional ventilation unit when the air quality is detected to be substandard.

[0045] The above solution involves installing an air inlet on the garage floor, which is connected to an exhaust fan and an exhaust duct. In the presence of vehicle exhaust, the exhaust fan draws in the exhaust gas from the inlet and discharges it outdoors through the exhaust duct, thus solving the technical problem of potential health hazards posed by vehicle exhaust in the garage.

[0046] In one of the alternative air purification solutions, such as Figure 4 As shown, the following steps can be followed:

[0047] Step S401: Detect the presence of vehicle exhaust gas at the air intake.

[0048] In step S402, if vehicle exhaust is detected, the exhaust fan is used to extract the vehicle exhaust drawn in from the air intake on the garage floor to the outside.

[0049] In step S403, while using the exhaust fan to extract the vehicle exhaust gas drawn from the air inlet on the garage floor to the outside, the fresh air fan of the two-way ventilation unit is turned on to introduce fresh outdoor air into the room, and the exhaust fan of the two-way ventilation unit is turned off to prevent the vehicle exhaust gas from spreading upwards.

[0050] Step S404: If the bidirectional ventilation unit detects that the air quality is substandard, start the fresh air fan and exhaust fan of the bidirectional ventilation unit. Steps S404 and S403 are not sequential; they can be performed either before or after each other.

[0051] 1) None of the road surface grilles have pressure generators when cars are driving. The circuits of the underground exhaust fans and underground air quality detection devices are disconnected and do not work. The air quality detection device at the air inlet of the ceiling bidirectional ventilation unit checks the air quality every time t. When the air quality is worse than the preset value, the corresponding bidirectional ventilation unit turns on the fresh air fan and exhaust fan to perform bidirectional ventilation. Otherwise, it does not work.

[0052] 2) When a vehicle passes under a grille, the pressure triggers the corresponding pressure generator under the grille to operate. This closes the circuits of the underground exhaust fan and the underground air quality detection device under the corresponding grille, energizing them. Simultaneously, the electrical energy generated by the pressure generator is transmitted to the circuit. First, the underground air quality detection device detects the air quality on the ground in that area. If the passing vehicle is an electric vehicle or a car whose front wheels have just entered the grille, no vehicle exhaust will be generated, so the air quality will not deteriorate. The underground exhaust fan will not operate, and the ceiling-mounted bidirectional ventilation unit will maintain its original operating state. If the passing vehicle is a gasoline-powered vehicle, vehicle exhaust will be generated, so the air quality will deteriorate. The controller will activate the underground exhaust fan in that area to extract the polluted air from the corresponding grille and a certain range around it to the outside. At the same time, the ceiling-mounted bidirectional ventilation unit will activate its fresh air fan to introduce fresh outdoor air to compensate for the polluted air exhausted by the underground exhaust fan, and will shut down the ceiling-mounted bidirectional ventilation unit's exhaust fan to prevent some vehicle exhaust from spreading upwards.

[0053] 3) If the underground exhaust fan was running before the car drove away from the grille, the exhaust fan circuit will be disconnected after a certain period of time to ensure that the residual exhaust gas is completely discharged.

[0054] Example 2

[0055] This application provides a fresh air system suitable for underground parking garages. The system extracts vehicle exhaust fumes from below ground level, preventing the exhaust fumes from spreading upwards and being inhaled by the human body, thus avoiding health damage. At the same time, it uses a pressure generator to compensate for electrical energy, and achieves energy-saving effects through certain gas detection and fan control methods.

[0056] The technical solution of this application mainly includes grid-type pavement and grille, ceiling-mounted bidirectional ventilation unit, exhaust fan and duct, pressure power generation device, air quality detection device, controller, etc.

[0057] 1) Grid-type pavement and grilles: The underground parking garage pavement is divided into several grid areas in the form of a frame. The size of each grid is slightly larger than the size of a car, and a grille is placed on each grid frame to allow vehicles to pass through while preventing debris from falling below.

[0058] 2) Fans and Ducts: A ventilation duct is connected to each grid formed by the road surface frame. Exhaust fans vent vehicle exhaust fumes from that grid area outdoors. Simultaneously, bidirectional ventilation fans are installed in the ceiling to introduce fresh outdoor air into the garage. They can also exhaust stale air from the garage when no vehicle exhaust fumes are generated, achieving indoor-outdoor air circulation. The range of operation for the exhaust fans can be a single grid area with vehicle traffic or multiple surrounding grid areas with vehicle traffic.

[0059] 3) Air quality detection devices: These are respectively installed under the road surface grille and at the exhaust and inlet of the ceiling-mounted two-way ventilation unit. The air quality detection device under the road surface grille is used to detect vehicle exhaust emissions, while the air quality detection device at the inlet of the ceiling-mounted ventilation unit is used to detect changes in air quality in the garage due to humidity or other reasons when vehicle exhaust emissions are not detected.

[0060] 4) Pressure Generator: The pressure generator is placed under the road surface grille. When a car drives in, it activates the exhaust fan and the road air quality detection device, which then starts working. Based on the detection results of the road air quality detection device, the exhaust fan is controlled. At the same time, the pressure generator can transmit the electricity it generates to the circuit to achieve energy saving. In addition to pressure sensing, the device for sensing whether a vehicle is driving can also be infrared sensing or camera recognition, etc.

[0061] Control schemes such as Figure 5 As shown:

[0062] Step S501: Check if a pressure generator is operating. If so, proceed to step S502; otherwise, proceed to step S505.

[0063] In step S502, the circuit of the corresponding underground air quality detection device is connected and powered on to detect the air quality.

[0064] Step S503: Determine whether the quality control is qualified. If yes, proceed to step S506; otherwise, proceed to step S504.

[0065] Step S504: The underground exhaust fan is turned on, and the bidirectional ventilation unit only turns on the fresh air fan.

[0066] In step S505, the circuits of the underground quality testing device and the exhaust fan are disconnected.

[0067] Step S506: The air detection device of the bidirectional air exchange unit detects the air quality.

[0068] Step S507: Determine whether the quality control is qualified. If yes, proceed to step S501; otherwise, proceed to step S508.

[0069] Step S508: The bidirectional ventilation unit starts bidirectional ventilation.
