[0040] Example 1

[0041] like Figure 1-7 As shown, the indoor smoke purification device in one embodiment of the present invention is used to purify air containing substances to be purified (such as wormwood smoke, wormwood oil, etc.), which includes a shell component 100, a pyrolysis component 300, an oil fume purification device 200, a cooling component 400 and a control component 500.

[0042] Housing components

[0043] The housing assembly 100 has an inner cavity for accommodating the pyrolysis assembly 300. Figure 1-3As shown, the outer shell assembly 100 as an example includes an outer box body 110, an outer rear cover plate 120 and an outer top cover plate 130. The outer box body 110 is a rectangular parallelepiped structure with a rear opening and a top opening. The outer rear cover plate 120 is provided at the rear opening, and the outer top cover plate 130 is provided at the top opening. The outer box body 110 is surrounded by a first front side plate 111, a first left side plate 112, a first right side plate 113 and a first bottom plate 114. The pyrolysis component 300 is installed in the inner cavity of the outer shell assembly 100, and a gap is left between the pyrolysis component 300 and the inner wall of the outer shell assembly 100 to form a cooling air duct. The outer shell assembly 100 is provided with a cold air inlet and a hot air outlet connected to the cooling air duct, and 150 is installed at the cold air inlet or the hot air outlet. In this embodiment, the housing assembly 100 further includes a partition 140, which is located within the inner cavity of the housing assembly 100 and divides it into an upper inner cavity 115 and a lower inner cavity 116. The pyrolysis assembly 300 is installed within the lower inner cavity 116. The cold air inlet is provided on the first left panel 112 and is in communication with both the upper inner cavity 115 and the lower inner cavity 116. The hot air outlet includes a bottom exhaust port provided on the first bottom panel 114 and a side exhaust port provided on the first right panel 113. 150 is installed at the air inlet. In this way, a portion of the cold air blown in by 150 enters the lower inner cavity 116, exchanges heat with the pyrolysis assembly 300, and is discharged from the bottom exhaust port. The other portion enters the upper inner cavity 115, exchanges heat with the partition 140, and is discharged from the side exhaust port. The partition 140 is made of a heat-insulating material, such as mica.

[0044] Oil fume purification device

[0045] Oil fume purification device 200 is used to initially separate oil fume from the air to be purified. It includes a primary oil separation device, which comprises a housing 210, a first collection container 220, and a rotating member 230. The housing 210 has an air duct, a first smoke inlet 211a, a first exhaust port 211b, and a first oil discharge port 215a connected to the air duct; the container port of the first collection container 220 is connected to the first oil discharge port 215a; and the rotating member 230 is disposed in the air duct between the first oil discharge port 215a and the first exhaust port 211b. As it rotates, the rotating member 230 guides the smoke entering the air duct through the first smoke inlet 211a and generates a vortex in the air duct on the air inlet side of the rotating member 230.

[0046] In the above-mentioned oil fume purification device 200, smoke enters the air duct from the first smoke inlet and generates a vortex in the air duct on the air inlet side of the fan. Due to the centrifugal force generated by the vortex, the smoke condenses on the inner wall of the air duct to form oil droplets. The oil droplets then enter the first collection container 220 through the first oil discharge port 215a, achieving a highly efficient smoke separation effect, ensuring that the discharged gas is clean and oil-free, and improving the service life and environmental performance of the equipment. Since the filter element is eliminated, the cost of regular filter element replacement is reduced; moreover, the gas entering the rotating part 230 is de-oiled gas, which prevents oil stains from remaining on the fan blades, causing the rotating part 230 to be overloaded and burn out, thereby extending the service life. In addition, the problem of unstable wind pressure due to oil stains accumulating on the filter element is avoided.

[0047] In one embodiment, the housing 210 is a vertically extending cylindrical structure. A first exhaust port 211b is located at the top of the housing 210, a first oil drain port 215a is located at the bottom of the housing 210, and a first smoke inlet 211a is located on the sidewall of the housing 210. The housing 210 includes a connecting air duct 217 connecting the first smoke inlet 211a and the first oil drain port 215a. With this structure, the first smoke inlet 211a and the first oil drain port 215a are staggered and located on the sidewall of the housing 210. The first smoke inlet 211a communicates with the first oil drain port 215a via a connecting air duct provided in the housing 210, preventing vortices within the air duct from being discharged through the first smoke inlet 211a, thereby improving the oil-gas separation effect.

[0048] In one embodiment, the housing 210 includes an outer shell 211 and a separator 214. The outer shell 211 has an upper section 212 and a lower section 213. The top of the upper section 212 is provided with a first exhaust port 211b. The upper section 212 houses a rotating member 230. The sidewall of the lower section 213 is provided with a first smoke inlet 211a. The lower end of the lower section 213 is detachably connected to the opening of the first collection container 220. The separator 214 is mounted within the lower section 213 and has a vertically extending separation cavity that communicates with the inner cavity of the upper section 212 to form the air duct. The lower end of the separator 214 is provided with a first oil drain port 215a. The separate design of the separator 214 and the outer shell simplifies the processing and assembly process and improves production efficiency.

[0049] In one embodiment, the separator 214 comprises an outer tube 216 and an inner tube 215. The outer tube 216 is mounted within the lower section 213. A through-hole is provided on the wall of the outer tube 216, opposite the first smoke inlet 211a. The inner tube 215 is positioned within the outer tube 216, and the connecting air duct 217 is formed therebetween. The separator 214 employs a double-layer structure, effectively reducing vibration and noise from the airflow and improving the stability of the device's operation. In this embodiment, a step is provided at the junction of the lower section 213 and the upper section 212. The lower end of the lower section 213 has an inwardly protruding lip. The outer tube 216 is positioned between the step and the lip, and the upper end of the inner tube 215 is connected to the upper end of the outer tube 216.

[0050] In one embodiment, the oil fume purification device 200 further includes a first heating module, which is used to heat the inner wall of the air duct. Since the inner wall of the air duct is prone to accumulation of oil stains, the inner wall of the air duct is heated by the first heating module to prevent the separated oil stains from solidifying on the inner wall of the air duct, causing blockage of the air duct or causing failure of the rotating parts. In this embodiment, the first heating module includes a first heating film 240, which is provided on the outer wall of the inner cylinder 215. It can prevent the outer wall of the inner cylinder 215 from accumulating oil stains, and can also heat the inner wall of the inner cylinder 215 to prevent the inner wall of the inner cylinder 215 from accumulating oil stains. The separator 214 is made of high-temperature resistant materials, such as plastic, metal, ceramic, etc.

[0051] In one embodiment, the upper section 212 includes a fan mounting section 212a and a necked section 212b connected sequentially from bottom to top. The rotating member 230 is mounted in the rotating member 230 mounting section, and the cross-sectional area of ​​the necked section 212b gradually decreases from bottom to top. With this structure, wind resistance is reduced while ensuring the formation of a vortex. In this embodiment, the first heating module also includes a second heating film (not shown in the figure). The second heating film is provided on the inner wall of the fan mounting section 212a to prevent oil stains from accumulating on the inner wall of the fan mounting section 212a, thereby preventing the air duct from being blocked or causing malfunction of the rotating member 230.

[0052] In one embodiment, the upper section 212 further includes a cylindrical connector portion 212c, which is located outside the constricted section 212b. The lower end of the connector portion 212c is connected to the upper end of the fan mounting section 212a. The connector portion 212c is connected to the end cap 250, which is provided with a connector 251 that connects to the air inlet of the pyrolysis assembly 300.

[0053] In one embodiment, rotating member 230 is an axial flow fan, comprising blades and a drive motor. In addition to creating vortexes in the airflow within the duct, the axial flow fan can also generate wind pressure between the first smoke inlet 211a and the first exhaust port 211b, thereby drawing the fumes into the duct. Alternatively, rotating member 230 may comprise a rotating shaft extending axially along the housing and a plurality of blades circumferentially disposed along the rotating shaft. The rotating shaft is connected to a drive device external to the duct. The blades may be plate-shaped, mesh-like, or bristle-like to increase contact area.

[0054] Pyrolysis components

[0055] The pyrolysis component 300 is used to further remove the air purified by the oil fume purification device 200. The pyrolysis component 300 includes a heat insulation component 310, a purification pipe 320, a heating component 330 and a cooling component 400, wherein the heat insulation component 310 has a heating chamber, and the heat insulation component 310 plays a role of heat preservation, which can reduce the heat loss of the heating component 330, prevent excessive heat loss, and improve the utilization efficiency of the heating component 330. As an example, the heat insulation component includes a rigid layer made of a rigid material and a heat insulation layer made of a heat insulation material located inside the rigid layer. The rigid layer plays a supporting and certain heat insulation role, while the heat insulation layer plays a role of heat preservation and heat insulation, and keeps the heat emitted by the heating component 330 in the heat insulation component as much as possible, thereby reducing energy loss and reducing its adverse effects on the environment outside the heat insulation component. It should be understood that the heat insulation layer should be ensured to have a certain thickness to improve the heat preservation and heat insulation effect.

[0056] In one embodiment, the rigid layer includes an inner box 311, an inner rear cover plate 312, and an inner top cover plate 313. The inner box 311 is rectangular in shape, with a rear opening and a bottom opening provided on the rear side and bottom surfaces, respectively. The inner rear cover plate 312 is used to close the rear opening, and the inner top cover plate 313 is used to close the top opening. As an example, the inner box 311 is surrounded by a second front panel 311a, a second left panel 311b, a second right panel 311c, and a second bottom panel 311d. The second front panel 311a of the inner box 311 is fixed to the first front panel 111 of the outer box 110, with a spacer provided between the two.

[0057] The heat insulation layer includes a first heat insulation board 315 and a second heat insulation board 316. The first heat insulation board 315 and the second heat insulation board 316 are both provided with grooves. The first heat insulation board 315 and the second heat insulation board 316 are arranged front to back relative to each other to form a heating chamber.

[0058] The purification pipe 320 includes a heating pipe section 321, an air inlet 322 and a first exhaust port 323. The heating pipe section 321 is located in the heating chamber, the air inlet 322 is located outside the heating chamber, and is communicated with the first exhaust port 211b of the oil fume purification device 200. The first exhaust port 323 is located outside the heating chamber and is communicated with the hot air inlet 441a of the cooling assembly 400. As an example, the heating pipe section 321 is curved (such as a spiral or a Chinese-shaped shape), which can make the heating pipe section 321 occupy more space in the heating chamber, and the length of the heating pipe section 321 located in the heating chamber is longer. The heating pipe section 321 extends in a spiral direction to form a heating chamber, and the heating element is inserted into the heating chamber. In this way, the heating pipe section 321 can more conveniently and fully absorb the heat emitted by the heating element, improve the heating effect and heating efficiency, facilitate heating the air in the purification pipe 320, and improve the pyrolysis efficiency.

[0059] Heating assembly 330 includes a heating element 331, located within the heating chamber and configured to heat purification tube 320 to thermally decompose the substances in the air being purified. In one embodiment, heating element 331 is a resistance wire. In one embodiment, heating assembly 330 also includes a temperature measuring element 332, located within the heating chamber and outside purification tube 320, for detecting the temperature within the heating chamber. Heating assembly 330 also includes a mounting base, to which both heating element 331 and temperature measuring element 332 are secured.

[0060] In one embodiment, the heating assembly 330 is detachably connected to the heat insulating member. Plug holes are provided on the inner top cover plate 313 and the partition plate 140, and the fixing seat is plugged into the plug holes.

[0061] In one embodiment, the heating pipe section 321 , the heating element 331 and the temperature measuring element 332 are all arranged in a vertical direction, so that the heating element 331 and the temperature measuring element 332 can be easily replaced.

[0062] The cooling assembly 400 includes a cooling pipe 441 and a second cooling fan 442. The cooling pipe 441 extends in a vertical direction. The cooling pipe 441 has a hot air inlet 441a, a cold air inlet and a first exhaust port 441b. The hot air inlet 441a is connected to the first exhaust port of the purification pipe 320. A second cooling fan 442 is provided at the cold air inlet. The opening of the first exhaust port 441b faces downward.

[0063] In one embodiment, the cooling assembly 400 further includes an anti-scalding sleeve 443 , which is sleeved on the lower portion of the cooling pipe 441 .

[0064] Control components

[0065] The control assembly 500 includes a control box 510 and a circuit board (not shown) disposed in the control box 510 . The circuit board is connected to the heating element 331 , the temperature measuring element 332 , 150 and the second cooling fan 442 .

[0066] As an example, the control box 510 is fixed to the upper portion of the first front side plate 111 of the outer box body 110, and the pyrolysis assembly 300 and the cooling assembly 400 are installed side by side on the front side of the housing assembly 100 and located below the control box 510. This structure is compact and occupies a small area.

[0067] Example 2

[0068] like Figure 8-10 The oil fume purification device of the indoor smoke purification device in this embodiment is substantially the same as the oil fume purification device in Example 1, except that the oil fume purification device further includes: a separation tube 260, an inner tube 270 and a second collecting container 280, a second smoke inlet 261 is provided on the side wall of the upper end of the separation tube 260, the second smoke inlet 261 is communicated with the first exhaust port 211b, the second smoke inlet 261 allows the gas discharged from the first exhaust port 211b to enter the inner cavity of the separation tube 260 in a vortex shape, and a second oil discharge port 262 is provided at the lower end of the separation tube 260; the inner tube 270 extends along the axial direction of the separation tube 260 and is located at the upper part of the inner cavity of the separation tube 260, the lower end of the inner tube 270 is communicated with the inner cavity of the separation tube 260, the upper end of the inner tube 270 is provided with a second exhaust port 271; the container mouth of the second collecting container 280 is communicated with the second oil discharge port 262.

[0069] The oily smoke discharged from the first exhaust port 211 enters the separation tube 260 through the second smoke inlet 261. Within the separation tube 260, it undergoes intense rotation, increasing the contact area between the oil droplets and the inner wall of the separation tube 260, thereby effectively improving the oil separation effect. Compared to single-stage separation, this two-stage separation process significantly reduces the amount of residual oil in the oily smoke, enhancing overall purification efficiency and preventing residual oil from clogging the intake pipe when the gas enters the pyrolysis assembly 300.

[0070] Furthermore, the oil fume purification device further includes a second heating module, which is used to heat the inner wall of the separation tube 260. As an example, the second heating module includes a third heating film 263, which is provided on the inner wall of the separation tube 260 to prevent the accumulation of oil stains on the inner wall of the separation tube 260, allowing the separated oil stains to smoothly enter the second collection container 280.

[0071] Furthermore, the separation pipe 260 is arranged side by side with the housing 210, and the first exhaust port 211b is connected to the second smoke inlet 261 via the connecting pipe 290. This makes the structure more compact and occupies less space.

[0072] The cooling component 400 of the indoor smoke purification device in this embodiment is substantially the same as the cooling component 400 in Example 1, except that: the cooling component 400 includes a cooling box 444 and a cooling pipe 441, the cooling box 444 is located below the outer shell component, and the top of the cooling box 444 is provided with a first cold air outlet 444a and a second cold air outlet 444b, the first cold air outlet 444a is connected to the cooling air duct, and the second cold air outlet 444b is provided with a second cooling fan 442, and the bottom of the cooling box 444 is provided with a hot air inlet (not shown in the figure), the cooling pipe 441 is located in the inner cavity of the cooling box 444, one end of the cooling pipe 441 is connected to the exhaust port of the purification pipe 320, and the other end is connected to the inner cavity of the cooling box 444.

[0073] The temperature of the gas after being treated by the pyrolysis device is relatively high, so it is further cooled by a cooling assembly. The cooling assembly includes a cooling box 444 and a cooling pipe 441, wherein the cooling pipe 441 is located in the inner cavity of the cooling box 444. A first cold air outlet 444a and a second cold air outlet 444b are provided on the top of the cooling box 444, and a cooling fan is provided to continuously introduce cold air into the cooling box 444. When the high-temperature gas passes through the cooling pipe 441, it undergoes sufficient heat exchange with the cold air in the cooling box 444, rapidly reducing the gas temperature. The cooled gas is eventually discharged through the exhaust port. After the gas undergoes high-temperature pyrolysis, although the residual harmful substances have been decomposed, the gas temperature is still relatively high. The cooling assembly rapidly cools the gas through the cooling pipe 441 and the cooling air duct, reducing the gas temperature to a safe emission range. The cooling process also further reduces the residual odor in the gas, ensuring that the discharged gas is clean and odorless, thereby improving the user experience.

[0074] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
