The fixing plate 5 is locked to the mesh box 21 through the locking mechanism 23. The inner side of the mesh box 21 is also inserted with a filter element 4. By adding a filter element 4 inside the oven body 1, the circulating flue gas can be filtered, reducing the amount of oil smoke and the particle size. At the same time, the UV lamp 17 added in the oven body 1 can reduce bacteria, viruses and other microorganisms in the air and improve air quality. When installing the filter element 4 of the mounting shell 8, the filter element 4 is put into the inner threaded sleeve 11 of the fixing plate 5, and then the mounting shell 8 is inserted into the filter element 4. Then, the mounting bolt 10 and the inner threaded sleeve 11 on the fixing plate 5 are used to install and fix it, so that the filter element 4 can be easily disassembled and replaced.

[0026] Filter element 4 includes a protective frame 401, a sealing sponge 402, activated carbon 403, and a protective net 404.

A locking groove 234 is opened at the upper end of the second connecting block 233, and the other end of the locking rod 232 is located inside the locking groove 234. When installing the filter screen inside the mesh box 21, it is only necessary to place the filter element 4 in the mesh box 21. The filter element 21 is inserted into the mesh box 21 and then inserted into the fixing plate 5. Then, the locking rod 232 on the first connecting block 231 is flipped and inserted into the locking groove 234 of the second connecting block 233 on the mesh box 21. When disassembling, simply remove the bracket 6, and then flip the locking rod 232 on the first connecting block 231 to disengage it from the locking groove 234 of the second connecting block 233. The mesh box 21 can then be pulled out. The filter element 4 inside the mesh box 21 has the same specifications and structure as the filter element 4 in the mounting shell 8, but there are some differences in specifications.

[0028] In addition, UV lamp 17 can decompose organic compounds in the air, such as formaldehyde, benzene and other harmful substances, reducing the pollution of the air by these substances; UV lamp 17 can oxidize and eliminate various odor substances, quickly eliminate odors, and at the same time kill putrefactive microorganisms and eliminate odor sources.

[0029] refer to Figure 3 The inner side of the mounting shell 8 is symmetrically provided with second through holes 13. The threaded end of the mounting bolt 10 moves through the second through hole 13. By providing the second through hole 13 on the inner side of the mounting shell 8, the mounting bolt 10 can easily connect to the inner threaded sleeve 11 on the fixing plate 5 after passing through the mounting shell 8.

[0030] refer to Figure 3The filter element 4 has a first through hole 12 on its inner side. The end of the inner threaded sleeve 11 away from the fixing plate 5 moves through the first through hole 12. Through the first through hole 12 on the filter element 4, the filter element 4 can be easily positioned and inserted into the inner threaded sleeve 11. It is also convenient to install and fix the filter element 4 with the mounting bolts 10 after the mounting shell 8 is inserted into the filter element 4.

[0031] refer to Figure 3 The airflow can be easily filtered through the square hole 18 on the fixed plate 5 and then through the filter element 4 in the mounting shell 8.

[0032] refer to Figure 4 The protective mesh 404 is made of one of the following materials: metal mesh, non-woven fabric, and glass fiber. The thickness of the protective mesh 404 is 4mm. By adding the protective mesh 404 to the outside of the activated carbon 403 of the filter element 4, the protective mesh 404 is used to filter out larger oil fume particles and grease, preventing these substances from clogging the subsequent activated carbon 403 layer, thereby extending the service life of the activated carbon 403 mesh and improving the filtration efficiency. The pre-filter is generally made of one of the following materials: metal mesh, non-woven fabric, or glass fiber, and has good oil resistance and corrosion resistance.

[0033] Operating principle and advantages: During operation, the motor 16 drives the impeller 15 to rotate, causing the air to be discharged through the upper and lower channels near the impeller 15. The upper channel is filtered by the filter element 4 at the square hole 18 and enters the upper part of the furnace. Then, after being guided by the air guide plate 19, the air enters the furnace through the mesh plate 7. The lower channel near the impeller 15 is filtered by the filter element 4 and enters the furnace. Under the action of the bracket 6, the air flows along the lower channel of the bracket 6 from the channel near the furnace door to the upper channel and then converges with the hot air flowing in the channel. The air then flows back through the return air port of the fixed plate 5 to filter the circulating flue gas. At the same time, the UV lamp 17 added to the oven body 1 can reduce bacteria, viruses and other microorganisms in the air and improve air quality.

[0034] When installing the filter element 4 in the mounting housing 8, the filter element 4 is fitted into the inner threaded sleeve 11 of the fixing plate 5, and then the mounting housing 8 is inserted onto the filter element 4. Finally, the mounting bolts 10 and the inner threaded sleeve 11 on the fixing plate 5 are used for installation and fixation. When installing the filter screen inside the mesh box 21, simply place the filter element 4 inside the mesh box 21 and insert it into the fixing plate 5. Then, flip the locking rod 232 on the first connecting block 231 and engage it with the locking groove 234 of the second connecting block 233 on the mesh box 21. The filter element 4 can be easily removed by simply taking out the bracket 6, flipping the lever 232 on the first connecting block 231 to disengage it from the slot 234 of the second connecting block 233, and then pulling out the mesh box 21. The filter element 4 is protected by adding protective nets 404 on both sides of the activated carbon 403. After placing it in the protective frame 401, the protective nets 404 on both sides of the activated carbon 403 are fixed on the protective frame 401 by the sealing sponge 402, which can provide a certain degree of protection for the activated carbon 403 in the filter element 4.
