DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be described in detail with reference to the drawings in the embodiments of the present utility model.

[0018] As Figure 1As shown in the figure, a water filtration air purification device with a semi-closed dust hood provided by the present utility model includes: a dust hood 1, which is integrally in a square body configuration, with a window provided on the front side. An activity door 2 is provided in the upper half of the window. By adjusting the opening degree of the activity door 2, it is convenient to operate and control the air intake speed and air volume of the dust hood, improving the purification efficiency and the comfort of the operator during work. The activity door 2 is of an arc-shaped curved surface structure. Installation guide rails 10 for the sliding and positioning of the activity door 2 are provided on both sides of the dust hood window, and an activity door sealing strip 3 is also provided on the upper edge. An exhaust port 4 and a check valve 5 for preventing reverse air flow are provided at the top of the dust hood 1. A base 19 is provided at the bottom of the dust hood 1. The base 19 adopts a frame structure. A bottom plate 18 can be provided on the base 19 as needed, and holes / ports can be opened on the bottom plate 18 as needed. Corresponding holes for the inlet and outlet of the water tank pipeline are opened on the side panel of the dust hood 1. A purification box. In this embodiment, the box body of the purification box and the dust hood 1 are designed in an integrated structure. An air inlet 9 with a grid is provided at the upper part of the front panel 6 on the side facing the window. The exhaust port of the purification box and the exhaust port 4 of the dust hood are combined and provided at the top. A centrifugal fan 8 is fixedly installed in the upper half of the purification box. The air inlet of the fan 8 is connected to the air inlet 9 of the purification box. The lower half of the purification box is a water tank. The air outlet of the fan 8 is installed facing the water tank. When the number of fans configured in the purification box is two or more, an anti-crosswind partition 7 is provided between the fans, and the bottom edge of the partition 7 is lower than the liquid level overflow port 13 of the water tank to ensure the independent and efficient operation of the fans. An automatic water level controller 12, an overflow port 13 and a drain valve 16 are provided on the water tank. During the operation of the device, the water level controller 12 automatically maintains the set water level of the water tank. Corresponding purification agents can also be added to the water tank to enhance the purification effect. The oil stain on the liquid surface of the water tank is discharged through the overflow port 13 while restricting the water level of the water tank. The drain valve 16 is used to empty the water tank when replacing the purification liquid or specifically cleaning the inside of the purification box. To facilitate the cleaning of the sediment at the bottom of the water tank, the automatic water level controller 12 and the drain valve 16 can be respectively arranged at both ends of the water tank. A liquid level gauge 15 is also provided on the water tank, through which the water level of the water tank and the water pollution situation in the water tank can be observed in real time. A differential pressure suction pipe 11 is provided at the bottom of the air inlet of the fan 8. The lower port of the differential pressure suction pipe 11 is lower than the overflow port 13 of the water tank to ensure that the lower port of the differential pressure suction pipe 11 is under the purified liquid surface in the water tank during the operation of the device. When the fan 8 operates, the outlet air pressure acts on the lower port of the differential pressure suction pipe 11 through the liquid in the water tank, and the negative pressure at the air inlet of the fan 8 acts on the upper port of the differential pressure suction pipe 11, forming a pressure difference with negative pressure at the upper port and positive pressure at the lower port in the differential pressure suction pipe 11, so as to suck the liquid in the water tank into the fan 8. Through the high-speed rotation of the impeller of the fan 8, collisions and centrifugal actions occur, generating liquid mist in the volute and the water tank and mixing with the inhaled dust. The oil fume, particulate matter and harmful gases are effectively adsorbed and decomposed by the purification liquid, enhancing the purification effect and at the same time realizing the self-cleaning inside the purification box. A water tank pipeline installation space is left at the bottom of the purification box.In addition, the device can also be configured with an intelligent control system for real-time monitoring of air quality and automatic adjustment of working states, including working modes, wind speeds, etc., to achieve intelligent operation. The control circuit board and display screen of this control system, together with the operation keyboard, are integrated within / on the control box 14 and fixedly installed on the outer side of the fume hood 1. Functional sensors and lighting can also be provided inside the fume hood as needed. Depending on different usage scenarios, the device can be installed on a cooking range or other workbenches, or a dedicated support stand can be configured. When using the device, observe the water level in the water tank through the level gauge 15, confirm that the valve of the automatic water level controller 12 is in the open state, adjust the movable door 2 to an appropriate opening at the window, turn on the power switch, and the control system is in standby. Power on through the operation panel / remote controller / Internet of Things artificial intelligence device, or it can also be automatically powered on through detection by the control system. The fan 8 starts to operate. Air forms a mixed airflow with oil fume / smoke / other foul gases through the window and is sucked into the purification box by the fan 8 from the air inlet 9. At the same time, the differential pressure suction pipe 11 sucks the purification liquid in the water tank into the fan 8. A water mist field is generated and formed by the impeller and volute of the fan 8, and is mixed with the sucked foul gases to achieve effective purification. Then, the gas-liquid mixed flow is ejected from the air outlet of the fan 8 at a high speed towards the liquid surface of the water tank, and continues to collide and mix in the liquid surface and the upper space inside the purification box, further achieving effective capture, adsorption, decomposition, and melting of the purification target. The purified air flow is discharged from the exhaust port 4. During the operation of the device, automatic cleaning of the inside of the purification box is achieved through the purification liquid, avoiding the accumulation and solidification of soot and oil stains inside the purification box, especially on the impeller and volute of the fan 8, which would reduce the efficiency of the fan 8 and the purification effect of the device. When replacing the purification liquid, open the drain valve 16 to empty the water tank.
