Description
Technical Field
[0001] This utility model relates to the field of air purification equipment technology, and in particular to a maintenance-free filter-type oil fume purification device. Background Technology
[0002] The main function of a negative ion electrostatic oil fume purifier is to purify kitchen air, remove harmful substances from oil fumes, and improve indoor air quality.
[0003] Negative ion electrostatic purifiers release negative ions to neutralize and remove harmful chemicals in the air, such as smoke, carbon monoxide, sulfur dioxide, and coal gas, produced during cooking, effectively purifying the fumes.
[0004] Traditional negative ion electrostatic oil fume purifiers have a pre-filter plate at the smoke inlet. The smoke needs to pass through the filter plate for preliminary filtration.

The system includes a negative ion electrostatic oil fume purifier 24, an exhaust pipe 25, an oil fume filter 26, and a nozzle 27. The first guide pipe 7 extends from the lower left end of the inner cavity of the housing 1, passing through the shell of the housing 1 and reaching the lower part of the left outer surface of the housing 1, where it is fixedly connected to the outer wall of the smoke collection hood 6.

A second guide bend 10 is fixedly installed between the upper end of the second guide pipe 9 and the left end of the third guide pipe 11. The negative ion electrostatic oil fume purifier 24 is fixedly installed on the third guide pipe. Between the right end of pipe 11 and the left end of exhaust pipe 25, the negative ion electrostatic oil fume purifier 24 uses a high-voltage electric field to charge the particulate matter in the oil fume with a positive charge, and then, through the action of the electric field, these charged particulate matter are adsorbed onto the dust collection plate. Exhaust pipe 25 extends from the upper right end of the inner cavity of housing 1 through the shell of housing 1 to the upper part of the outer surface of the right end of housing 1. Drainage baffle 15 is fixedly installed at the right end of the inner cavity of the first guide pipe 7. The upper end of liquid outlet pipe 12 is fixedly connected to the bottom of the right end of the first guide pipe 7. Liquid outlet pipe 12 is located to the right of drainage baffle 15. The left side can guide the flow of oil fumes, and the right end can block the water flow, so that the water can be fully discharged through the liquid outlet pipe 12. The oil fume filter screen 26 is fixedly installed at the lower end of the inner cavity of the second guide pipe 9. The upper end of the liquid inlet pipe 19 extends from the middle of the outer wall of the right side of the second guide pipe 9 into the middle of the inner cavity of the second guide pipe 9. The nozzle 27 is located in the middle of the inner cavity of the second guide pipe 9, and the nozzle 27 is fixedly installed on the upper outer surface of the liquid inlet pipe 19. The nozzle 27 is located directly above the oil fume filter screen 26, which can fully clean the oil stains on the oil fume filter screen 26.
[0029] The sewage storage tank 14 is fixedly installed on the left side of the bottom of the inner cavity of the tank body 1, and the lower outer surface of the outlet pipe 12 is fixedly connected to the middle of the upper outer surface of the sewage storage tank 14. The solenoid valve 13 is fixedly installed on the outlet pipe 12 to prevent oil fumes from entering the sewage storage tank 14 through the outlet pipe 12 when there is no water flow. The laser level sensor 16 is fixedly installed on one corner of the upper outer surface of the sewage storage tank 14. The laser level sensor 16 calculates the liquid level by emitting a laser beam and receiving its reflected signal. The laser level sensor 16 is connected to an external alarm. The drain pipe 17 is fixedly installed on the right side of the lower end of the front outer surface of the sewage storage tank 14. The drain valve 18 is fixedly installed on the drain pipe 17 to facilitate the discharge of sewage from the sewage storage tank 14.
[0030] The cleaning fluid storage tank 21 is fixedly installed on the right side of the bottom of the inner cavity of the tank body 1, and the water pump 20 is fixedly installed on the middle of the upper outer surface of the cleaning fluid storage tank 21. The lower outer surface of the inlet pipe 19 is fixedly connected to the upper outer surface of the water pump 20. The lower outer surface of the water pump 20 is fixedly connected to the suction pipe, and the lower end of the suction pipe extends into the bottom of the inner cavity of the cleaning fluid storage tank 21. The water supply pipe 22 is fixedly installed on one side of the top of the cleaning fluid storage tank 21. Through the operation of the water pump 20, the liquid inside the cleaning fluid storage tank 21 is drawn to the nozzle 27 and sprayed onto the oil fume filter 26 to achieve automatic cleaning. The top cover 23 is threadedly connected to the upper outer surface of the water supply pipe 22 to facilitate the filling of the cleaning fluid storage tank 21.
[0031] A door 2 is fixedly installed on the lower part of the front outer wall of the housing 1, and an inspection plate 3 is installed on the upper part of the front outer wall of the housing 1 to facilitate the maintenance of the device. Support legs 4 are fixedly connected to the four corners of the lower outer surface of the housing 1 to improve the stability of the device.
[0032] Working principle: During use, oil fumes enter the first guide pipe 7 through the fume collection hood 6, are guided to the second guide pipe 9 through the first guide bend 8, pass through the oil fume filter 26, where the oil is filtered, and then pass through the second guide bend 10 to flow into the third guide pipe 11. Finally, after being purified by the negative ion electrostatic oil fume purifier 24, the fumes are discharged through the exhaust pipe 25. Then, the water pump 20 is started, and the water pump 20 supplies the cleaning liquid in the cleaning liquid storage tank 21 to the nozzle 27 through the liquid inlet pipe 19. The nozzle 27 washes the oil fume filter 26. At this time, the solenoid valve 13 is opened, and the oil fumes are blocked by the flow baffle 15 as the water flows through the guide plate and enter the sewage storage tank 14. The laser liquid level sensor 16 detects the amount of sewage in the sewage storage tank 14. When the liquid level is too high, the alarm is triggered, prompting personnel to refill the cleaning liquid storage tank 21 and discharge the sewage from the sewage storage tank 14.
