[0027] This application relates to a fire safety ventilation device, which includes a ventilation chamber 1000, a first filter structure 2100, and an airflow generating assembly. The first filter structure 2100 is disposed in the ventilation chamber 1000, which has an air inlet 1101 and an air outlet 1102. Under the action of the airflow generating assembly, airflow enters the ventilation chamber 1000 from the air inlet 1101 and exits from the air outlet 1102. The first filter structure 2100 is used to filter the airflow entering from the air inlet 1101, so as to filter and purify the smoke entering the ventilation chamber 1000.
[0028] Furthermore, the fire safety ventilation device includes a surface cleaning structure 2101, which is disposed in the ventilation chamber 1000 and located on the side of the first filter structure 2100 facing the air inlet 1101. The surface cleaning structure 2101 is used to clean the surface of the first filter structure 2100. Specifically, the surface cleaning structure 2101 is used to remove impurities adhering to the surface of the first filter structure 2100, thereby preventing the first filter structure 2100 from becoming clogged and preventing the first filter structure 2100 from failing to filter and purify smoke.
[0029] The airflow generating assembly includes a turbine fan 3100 disposed in the ventilation chamber 1000. Under the action of the turbine fan 3100, airflow enters the ventilation chamber 1000 through the air inlet 1101. Further, a surface cleaning structure 2101 is connected to the shaft of the turbine fan 3100. The shaft of the turbine fan 3100 drives the surface cleaning structure 2101 to rotate, causing the surface cleaning structure 2101 to move on the surface of the first filter structure 2100, thereby completing the cleaning of the first filter structure 2100.
[0030] Understandably, one end of the shaft is connected to the turbine fan 3100, and the other end is connected to the surface cleaning structure 2101.
[0031] In some real-time configurations, the first filtration structure 2100 includes a filter plate. The ventilation chamber 1000 extends through both ends, forming an air inlet 1101 and an air outlet 1102. The filter plate is vertically arranged within the ventilation chamber 1000, with its sides perpendicular to the through direction of the ventilation chamber 1000. Specifically, the ventilation chamber 1000 is a horizontally through chamber, with the filter plate arranged vertically.
[0032] In this case, the surface cleaning structure 2101 contacts the surface of the filter plate and cleans the impurities attached to the filter plate, avoiding clogging of the filter pores.
[0033] Of course, the first filter structure 2100 can also be designed as a filter screen, which is installed upright in the ventilation chamber 1000.
[0034] In some examples, the surface cleaning structure 2101 includes a scraper, with at least one scraper arranged to extend radially along the axis of rotation.
[0035] The surface cleaning structure 2101 also has at least the following alternative embodiments.
[0036] In some alternative embodiments, the surface cleaning structure 2101 includes a brush, with at least one brush provided.
[0037] In some embodiments, the fire safety ventilation device includes a dust collection assembly disposed on the side wall of the ventilation chamber 1000, which is used to collect impurities that are removed from the first filter structure 2100 by the surface cleaning structure 2101.
[0038] Specifically, the dust collection assembly includes a dust collection box 4100, which is disposed on the side wall of the ventilation chamber 1000, located at the bottom of the ventilation chamber 1000, and below the first filter structure 2100 and the surface cleaning structure 2101, so that the cleaned impurities fall into the dust collection box 4100.
[0039] Understandably, the bottom side wall of the ventilation chamber 1000 is provided with a connection port to the dust collection box 4100.
[0040] Furthermore, the dust collection box 4100 is provided with a discharge port, which is located at the bottom of the dust collection box 4100. A valve body is provided at the discharge port so that the user can open and close the discharge port.
[0041] In some examples, the dust collection assembly includes a vibrator 4200 disposed on the side wall of the dust collection box 4100. The dust collection box uses the vibrator 4200 to vibrate and discharge material, and the vibration generated by the vibrator 4200 prevents impurities from adhering to the side wall of the dust collection box 4100.
[0042] In some embodiments, the fire safety ventilation device includes a second filter structure 2200, which is disposed at the air outlet 1102. The airflow in the ventilation chamber 1000 is discharged after being treated by the second filter structure 2200.
[0043] Specifically, the second filtration structure 2200 includes an activated carbon plate or a filter screen.
[0044] In some examples, the second filter structure 2200 is removable at the air outlet 1102 to allow for cleaning or replacement of the second filter structure 2200.
[0045] Furthermore, the second filter structure 2200 is installed in the air outlet 1102 in a pull-out manner. Specifically, the side wall of the air outlet 1102 is provided with a slot, one end of the second filter structure 2200 is inserted into the slot, and the other end of the second filter structure 2200 is provided with a handle for the user to insert and remove.
[0046] In some embodiments, the fire safety ventilation device includes a third filter component. The airflow in the ventilation chamber 1000 is processed by the first filter structure 2100, then by the third filter component, and finally by the second filter structure 2200 before being discharged, thus achieving three-stage filtration of the smoke and achieving the purpose of smoke filtration and purification.
[0047] Specifically, the third filter assembly includes an electrostatic ion generator 5100, electrode rods 5200, and at least one pair of electrode dust collection plates 5300. The electrostatic ion generator 5100 is disposed on the side wall of the ventilation chamber 1000. Two electrode rods 5200 are provided, and the electrode rods 5200 are connected to the electrostatic ion generator 5100. The electrode rods 5200 and the electrode dust collection plates 5300 are disposed in the ventilation chamber 1000. It can be understood that the electrode dust collection plate 5300 connected to the positive electrode and the electrode dust collection plate 5300 connected to the negative electrode are paired.
[0048] Furthermore, the electrostatic ion generator 5100 is located at the top of the ventilation chamber 1000. In the ventilation chamber 1000, the electrode rod 5200 and the electrode dust collection plate 5300 are located on the side of the first filter structure 2100 facing the air outlet 1102, and the electrode rod 5200 is located between the electrode dust collection plate 5300 and the first filter structure 2100.
[0049] In some examples, the electrode rod 5200 is arranged vertically or horizontally.
[0050] In some examples, the electrode dust collection plate 5300 is arranged horizontally or vertically.
[0051] In some examples, the electrode dust collection plates 5300 are configured in three pairs.
[0052] It should be noted that the electrostatic ion generator 5100, together with the electrode rod 5200, generates a strong electrostatic field in the ventilation chamber 1000. This strong electrostatic field then targets the bacteria and dust particles in the smoke that have undergone preliminary filtration by the first filter structure 2100. When these impurity particles pass between the electrode dust collection plates 5300, due to the principle of like charges repelling and unlike charges attracting, the bacteria or dust particles with the anode will be adsorbed onto the electrode dust collection plate 5300 with the negative electrode, thus achieving secondary filtration.
[0053] In some embodiments, the airflow generating assembly includes a fan bracket 3200 disposed in a ventilation chamber 1000 and fixedly connected to the side wall of the ventilation chamber 1000. The shaft of the turbine fan 3100 is disposed on the fan bracket 3200 and is rotatable on the fan bracket 3200.
[0054] Furthermore, the fan bracket 3200 is configured as a frame structure to prevent it from blocking the ventilation chamber 1000 and to facilitate airflow. In some examples, the fan bracket 3200 includes a horizontal beam and a vertical beam, which intersect perpendicularly and are fixedly connected. The two ends of the horizontal beam are fixedly mounted on the side wall of the ventilation chamber 1000, and the two ends of the vertical beam are fixedly mounted on the side wall of the ventilation chamber 1000.
[0055] Regarding the structure of the fan bracket 3200, at least the following alternative embodiments exist.
[0056] In some alternative embodiments, the fan bracket 3200 is configured as a horizontal or vertical beam.
[0057] In some alternative embodiments, the fan bracket 3200 is configured as a tripod bracket.
[0058] In some examples, to improve the smoothness of the rotation of the turbine fan 3100 and the surface cleaning structure 2101, at least two fan brackets 3200 are provided, which are spaced apart along the axial direction of the turbine fan 3100.
[0059] In some examples, the fan bracket 3200 is configured as a single unit, with the turbine fan 3100 and the surface cleaning structure 2101 located on opposite sides of the fan bracket 3200. The fan bracket 3200 is located on the side of the first filter structure 2100 facing the air inlet 1101, the surface cleaning structure 2101 is located between the fan bracket 3200 and the first filter structure 2100, and the turbine fan 3100 is located on the side of the air inlet 1101 on the fan bracket 3200.
[0060] It should be noted that the airflow generating component includes a fan driver, which is disposed on the side wall of the ventilation chamber 1000. The fan driver provides power to the turbine fan 3100 and is used to drive the turbine fan 3100 to rotate.
[0061] In some examples, the fan driver includes a motor 3301 and a drive belt 3302, both of which have pulleys on their shafts. The drive belt 3302 extends into the ventilation chamber 1000, with one end connected to the pulley on the shaft of the motor 3301 and the other end connected to the pulley on the shaft of the turbine fan 3100.
[0062] Furthermore, a protective box 3303 is provided on the outer wall of the ventilation chamber 1000, and the motor 3301 is installed inside the protective box 3303.

[0064] In some alternative embodiments, the motor 3301 drives the turbine fan 3100 via chain drive.
[0065] In some alternative embodiments, the motor 3301 drives the turbine fan 3100 via gears.
[0066] In some embodiments, the ventilation chamber 1000 is provided with an openable door 1200, which is located on the side of the ventilation chamber 1000. The user can clean the ventilation chamber 1000 by opening the door 1200.
