[0028] In some technical solutions, optionally, the liquid storage structure is a sponge.

[0029] In this technical solution, the sponge can be used to store cleaning liquid, and because the sponge itself has a porous structure, the smoke entering the third cavity section can also pass through its pores, so that the cleaning liquid purifies the smoke passing through the sponge pores.

Figure 4 As shown, a plurality of drip holes 1451 are provided on the infiltration pipeline 145 , and the cleaning liquid can flow into the liquid storage structure 141 through the drip holes 1451 .

[0085] The cleaning liquid flows into the liquid storage structure 141 from the drip hole 1451 , which can ensure that the cleaning liquid infiltrates the liquid storage structure 141 , so that the cleaning liquid can purify the smoke passing through the liquid storage structure 141 .

[0086] It should be emphasized that at least part of the infiltration pipeline 145 is arranged in the liquid storage structure 141. In this pipeline laying method, the cleaning liquid simultaneously and widely infiltrates the liquid storage structure 141 through multiple drip holes 1451 to improve the effect of the cleaning liquid in purifying the flue gas.

[0087] In some embodiments, optionally, Figure 3 As shown, the spray assembly 140 further includes a liquid collecting tank 146. The liquid collecting tank 146 is disposed in the third cavity section 123. The liquid collecting tank 146 is communicated with the liquid storage structure 141.

[0088] By providing the liquid collecting tank 146, on the one hand, the liquid storage structure 141 can directly absorb the cleaning liquid in the liquid collecting tank 146; on the other hand, the cleaning liquid pumped to the liquid storage structure 141 by the pump body 143 can fall into the liquid collecting tank 146 under its own gravity, which is convenient for recycling the cleaning liquid. In addition, the pump body 143 can pump the cleaning liquid in the liquid collecting tank 146 to the liquid storage structure 141 to achieve the purpose of circulating pumping.

[0089] In some embodiments, optionally, the liquid storage structure 141 is a sponge.

[0090] The sponge can be used to store cleaning liquid, and because the sponge itself has a porous structure, the smoke entering the third cavity section 123 can pass through its pores, so that the cleaning liquid purifies the smoke passing through the sponge pores.

[0091] In addition, by configuring the liquid storage structure 141 as a sponge, this design is low-cost and easy to clean and replace.

[0092] In some embodiments, the liquid storage structure 141 optionally has an air hole and a liquid storage tank. The liquid storage tank is used to store the cleaning liquid. The air hole is used to allow smoke to pass through. When the smoke passes through the air hole of the liquid storage structure 141, the cleaning liquid can purify the smoke.

[0093] In some embodiments, optionally, Figure 3 and Figure 5 As shown, the filter assembly 160 includes an adsorbent 161. The adsorbent 161 is disposed in the first cavity section 121. The adsorbent 161 can not only filter particulate matter impurities in the flue gas, but also adsorb and purify the residual cleaning liquid in the flue gas.

[0094] The smoke enters the chamber 120 through the inlet 131 and is discharged through the spray assembly 140 , the fan 150 , the adsorbent 161 and the outlet 132 .

[0095] In some embodiments, optionally, the adsorbent 161 includes at least one of the following or a combination thereof: activated carbon particles, an activated carbon plate, a collection bag filled with activated carbon particles, and a filter.

[0096] When the number of adsorbents 161 is one, the adsorbent 161 is any one of activated carbon granules, activated carbon plates, collection bags filled with activated carbon granules, and filter screens; when the number of adsorbents 161 is multiple, the multiple adsorbents 161 are any combination of activated carbon granules, activated carbon plates, collection bags filled with activated carbon granules, and filter screens.

[0097] By configuring the adsorbent 161 as activated carbon particles, it is beneficial to increase the contact area between the adsorbent 161 and the flue gas, thereby improving the purification effect of the adsorbent 161.

[0098] By setting the adsorbent 161 as an activated carbon plate, it is helpful to increase the contact area between the adsorbent 161 and the flue gas, thereby improving the purification effect of the adsorbent 161. Optionally, the activated carbon plate is directly placed on the fan 150, and does not need to be connected to the cavity 120 of the cavity 120. Optionally, the activated carbon plate is detachably connected to the cavity wall of the cavity 120. The above design methods are all for the convenience of users to maintain or replace the adsorbent 161.

[0099] By arranging a collection bag containing activated carbon particles in the third cavity section 123, it is more convenient for users to replace the activated carbon particles than directly arranging the activated carbon particles, and it is helpful to improve the cleanliness of the cavity 120. In addition, this design method is helpful to increase the contact area between the adsorbent 161 and the smoke, thereby improving the purification effect of the adsorbent 161.

[0100] By setting the adsorbent 161 as a filter, not only the particulate impurities in the flue gas can be filtered, but also the cleaning liquid remaining in the flue gas can be adsorbed and purified.

[0101] Optionally, the filter is a HEPA (High efficiency particular Air) filter, that is, a high efficiency air filter, which can capture micron-level particles in the smoke.

[0102] In some embodiments, optionally, Figure 3 and Figure 5 As shown, the oil fume purification device 100 further includes a noise reduction layer 170. The noise reduction layer 170 is disposed in the cavity 120.

[0103] The noise reduction layer 170 can be provided to provide sound insulation and noise reduction, thereby improving user experience.

[0104] It should be noted that the noise reduction layer 170 can be disposed at any position of the cavity. Specifically, the noise reduction layer 170 is disposed only in one of the first cavity segment, the second cavity segment, and the third cavity segment; or, the noise reduction layer 170 is disposed in two or three of the first cavity segment, the second cavity segment, and the third cavity segment.

[0105] In some embodiments, optionally, the housing 110 is a one-piece structure.

[0106] By configuring the housing 110 as an integrated structure, it is beneficial to ensure the structural strength of the housing 110 itself, and it can also reduce the number of parts and components and improve assembly efficiency.

When the cover 134 and the access hole 133 are in a connected state, the access hole 133 is in a closed state, and the smoke in the cavity 120 will not flow out of the cavity 120 through the access hole 133; when the cover 134 and the access hole 133 are in a non-connected state, the access hole 133 is in an open state, which is convenient for the user to take or place the device or parts in the cavity 120, thereby achieving maintenance, cleaning or replacement.

[0111] In some embodiments, optionally, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the housing 110 includes a first housing 111 and a second housing 112. The second housing 112 is connected to the first housing 111. The second housing 112 and the first housing 111 enclose a cavity 120.

[0112] By setting the shell 110 as a first shell 111 and a second shell 112, when the first shell 111 and the second shell 112 are in a connected state, the first shell 111 and the second shell 112 enclose a cavity 120, ensuring that the smoke entering the cavity 120 can be purified under the action of the spray assembly 140 and the filter assembly 160; when the first shell 111 and the second shell 112 are in a disconnected state, the user can open the cavity 120 and maintain, clean or replace the components in the cavity 120.

[0113] In some embodiments, optionally, the first shell 111 and the second shell 112 are detachably connected.

This design is simple to operate and is conducive to the user's quick disassembly and assembly of the shell 110.

[0116] Optionally, the first shell 111 and the second shell 112 are detachably connected by a sliding structure. The user can open or close the cavity 120 by pushing and pulling, which is convenient and quick. Optionally, the sliding structure includes a slider and a slide rail. The slider is provided on one of the first shell 111 and the second shell 112, and the slide rail is provided on the other of the first shell 111 and the second shell 112.

[0117] In some embodiments, optionally, the oil fume purification device 100 further includes at least one of the following or a combination thereof: a first drawer structure 181 , a second drawer structure 182 , and a third drawer structure 183 .
