The drawer-type electrostatic field generator 5 is 30-35cm high. The fumes generated during grilling on the grill 2 rise to the drawer-type electrostatic field generator 5 inside the fume purification box 3 for high-voltage electric field purification. Due to the adsorption effect of high-voltage electrostatics, larger oil fume particles are attracted. The atomized oil fume gas enters the fume buffer chamber 30, where it is blocked and filtered by the equalization filter plate 34, distributing the fumes within the chamber. Under the adsorption of the exhaust fan 4, the oil fumes in the fume buffer chamber 3 are then removed. Discharge; When it is necessary to clean the drawer-type electrostatic field generator 5, pull the drawer-type electrostatic field generator 5 out from the drawer opening 32 for cleaning and maintenance. Multiple sealing doors 6 are provided on the front surface of the vehicle body 1, and a first handle 60 is provided on each sealing door 6. Opening the sealing door 6 through the first handle 60 allows barbecue utensils to be placed inside the space of the vehicle body 1, greatly increasing the storage space for barbecue utensils. The barbecue cart is not only convenient to use and has a good purification effect, but it can also be quickly cleaned and maintained, and it has a large storage space.
[0024] like Figure 1 , Figure 2 and Figure 3As shown, an oil-guiding filter plate 32a is inclinedly installed on the inner wall of the flue gas purification box 3 at the lower end of each drawer opening 32. An oil-guiding filter plate 32a inclined to the left and right is also installed below the drawer-type electrostatic field generator 5.

The filtered and collected oil flows through the oil-guiding filter plate 32a to the oil collection trough 32b located at the lowest position of the oil-guiding filter plate 32a. The minimum distance between the oil-guiding filter plate 32a and the drawer-type electrostatic field generator 5 is 3-5 cm. After preliminary filtration by the oil-guiding filter plate 32a... The oil fumes continue to rise into the drawer-type electrostatic field generator 5, where they are captured and collected by static electricity, thus quickly completing the collection and purification of the oil fumes and improving the purification effect of the barbecue area. Above each end of each oil guide filter plate 32a, there is a pair of symmetrical sliding support rails 33 for supporting the drawer-type electrostatic field generator 5. The two sides of the drawer-type electrostatic field generator 5 are slidably supported on the sliding support rails 33. When it is necessary to clean the drawer-type electrostatic field generator 5, the drawer-type electrostatic field generator 5 is pulled out from the drawer opening 32 along the sliding support rails 33 for cleaning and maintenance.
[0025] like Figure 1 , Figure 2 As shown, the top wall of the flue gas buffer chamber 30 is composed of multiple movable cover plates 300. The rear side of the movable cover plate 300 is hinged to the rear side wall of the top of the flue gas buffer chamber 30, and the front side of the movable cover plate 300 covers the front side of the top of the flue gas buffer chamber 30. An exhaust fan 4 is set at the center of the top of the movable cover plate 300. The number of movable cover plates 300 is the same as the number of equalizing filter plates 34, and the movable cover plate 300 is set at the top of the flue gas buffer chamber 30 above each equalizing filter plate 34. A second handle 301 is set at the top front side of the movable cover plate 300. Each equalizing filter plate 34 is arranged in a figure-eight or inverted V shape in the lower end of the flue gas buffer chamber 30. The movable cover plate 300 can be opened by the second handle 301, so that the equalizing filter plate 34 set in the flue gas buffer chamber 30 above each drawer-type electrostatic field generator 5 can be taken out. After the equalizing filter plate 34 is taken out from the inside of the flue gas buffer chamber 30, it can be cleaned and maintained.
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the drawer-type electrostatic field generator 5 includes a horizontally arranged drawer housing 500, a plurality of anode cylinders 501 vertically and tightly disposed within the drawer housing 500, and discharge electrodes 502 disposed along the central axis of each anode cylinder 501. An electrode support frame 503 is horizontally disposed at the top of the drawer housing 500. The fixed end of the discharge electrode 502 is vertically connected to the electrode support frame 503, and the free end of the discharge electrode 502 extends vertically downward from the upper port of the anode cylinder 501 to be flush with the lower port. Insulating support columns 504 are respectively disposed on the front and rear side walls on both sides of the drawer housing 500. The front of the electrode support frame 503... The rear two ends are fixed to the top outer wall of the drawer housing 500 by insulating support columns 504; insulators 505 are embedded in the insulating support columns 504, and the front and rear two ends of the electrode support frame 503 are fixed to the insulating support columns 504 by insulators 505; sliding support blocks 506 are provided on the two side walls of the bottom of the drawer housing 500, and a third handle 507 is provided on the front side wall of the drawer housing 500. The drawer housing 500 is inserted into each drawer opening 32 of the flue gas purification box 3. The electrode support frame 503 is set on the outside of the drawer housing 500 by insulating support columns 504. During the rising process of the oil fumes, due to the sliding... The support rails 33 are in close contact with the bottom sides of the drawer housing 500. Under the adsorption of the exhaust fan 4, the oil fumes can quickly rise into the flue gas buffer chamber 30 and be quickly discharged, thereby preventing and avoiding contact between the oil fumes and the insulator 505, improving the insulation of the insulator 505, effectively improving the electric field safety and stability of the high-voltage electrostatic box 3, and ensuring the safe operation of the drawer-type electrostatic field generator 5. The discharge electrodes 502 are set inside the anode cylinder 501. After the drawer-type electrostatic field generator 5 is energized, an ionization area is formed in the anode cylinder 501 area where each discharge electrode 502 is located, so that the oil fume particles passing through the anode cylinder 501 area are ionized, and some of the oil fume particles are discharged. Due to gravity, the oil fume particles fall onto the oil filter plate 32a. The remaining oil fume particles are electrostatically purified in the anode cylinder 501 under the action of the exhaust fan 4, then rise into the flue gas buffer chamber 30 and are discharged from the outlet of the exhaust fan 4, thus achieving the effect of electrostatic purification. When cleaning and maintaining the drawer-type electrostatic field generator 5, the drawer housing 500 is pulled out from the drawer opening 32 of the flue gas purification box 3 through the third handle 507, so that the discharge electrode 502, anode cylinder 501 and electrode support frame 503 can be cleaned and maintained. This enables the rapid purification of oil fumes generated during grilling and the quick disassembly and cleaning and maintenance of the drawer-type electrostatic field generator 5.
[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
