[0003] The present invention aims to solve one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the present invention provides a flow guide assembly.

[0005] A second aspect of the present invention provides an oil fume treatment device.

[0006] In view of this, according to a first aspect of the present invention, a guide assembly is proposed for an oil fume treatment device, comprising: a frame, an air inlet is provided on the frame; a grille, the grille is connected to the frame, and the grille is arranged on the air inlet; a first guide member, the first guide member is arranged on the frame, the first guide member is located between the bottom surface of the grille and the frame, and the first guide member is suitable for guiding liquid flowing down from the grille.

[0007] The flow guide assembly provided by the present invention includes a frame, a grille and a first flow guide. The frame is provided with an air inlet. The grille is embedded in the air inlet of the frame. The grille can guide the air flowing through the air inlet. The first flow guide is arranged on the frame. The first flow guide is located between the bottom surface of the grille and the frame. The first flow guide is arranged opposite to the grille. The first flow guide can guide the liquid condensed on the grille so that the condensed liquid can flow along the first flow guide to the oil fume channel of the oil fume treatment device, thereby preventing the condensed liquid from flowing from the frame to the outer wall of the oil fume treatment device. The flow guide assembly provided by the present invention not only guides the gas through the grille so that the gas flowing through the grille can enter the smoke guide channel of the oil fume treatment device, but also guides the liquid condensed on the grille. Furthermore, by arranging the flow guide assembly on the oil fume treatment device, the oil pollution condition of the oil fume treatment device is improved, and the cleaning frequency and difficulty of consumers are reduced.

[0008] It is understandable that the oil fume treatment device can be selected as a side suction range hood or an integrated stove. During operation, the oil fume treatment device sucks air with oil fume into the oil fume treatment device through the grille, and the oil and water in the air condense on the grille. The oil and water on the grille flow through the first guide member to the inside of the oil fume treatment device. An oil receiving box is also provided inside the oil fume treatment device, which is specifically provided in the smoke guide channel of the oil fume treatment device and can guide the condensed oil and water.

[0009] In addition, the flow guide component in the above technical solution provided by the present invention may also have the following additional technical features:

[0010] In one possible design, the first air guide includes: a first plate for supporting the grille, the first plate is connected to the frame, and the first plate extends into the air inlet along the air inlet direction; a second plate, the second plate is connected to the first plate, and an angle is set between the second plate and the first plate.

[0011] In this design, the first guide member includes a first plate and a second plate, the first plate is connected to the second plate, and an angle is set between the first plate and the second plate, so that the first plate and the second plate form a stepped structure, and the first plate can support the grille, so that the liquid condensed on the grille flows downward to the first plate and continues to flow downward from one side of the first plate. The second plate connected to the first plate can prevent the oil from flowing downward from the other side of the first plate, thereby achieving a liquid diversion effect on the first guide member.

[0012] In a possible design, the angle between the first plate and the second plate is greater than or equal to 90° and less than or equal to 180°.

[0013] In this design, the angle between the first plate and the second plate is set to be greater than or equal to 90° and less than or equal to 180°, which can effectively prevent the grille from falling off the first guide member and enhance the stability of the grille installation.

[0014] In a possible design, the first air guide member further includes: a positioning protrusion, which is arranged on the first plate member and is used to support the grille.

[0015] In this design, the first guide member also includes a positioning protrusion, which is arranged on the first plate. The positioning protrusion contacts and abuts against the grille box, so that a certain gap is formed between the grille and the frame, so that the liquid remaining on the grille can continue to flow downward through the gap, thereby improving the effect of the guide component on liquid diversion and avoiding oil spillage.

[0016] In a possible design, the distance between the highest point of the positioning protrusion and the first plate along the gravity direction is greater than or equal to 1 mm and less than or equal to 10 mm.

[0017] In this design, the height of the positioning protrusion is limited, thereby limiting the width of the gap between the grille and the frame, so that the gap between the grille and the frame is greater than or equal to 1 mm, which can allow the oil flowing through the gap to continue to flow downward, thereby avoiding the gap from being blocked. The gap between the grille and the frame is less than or equal to 10 mm, which can improve the installation stability of the grille and the frame and prevent the grille from falling off the frame.

[0018] In a possible design, the first flow guide further includes: a first through hole, which is disposed in the first plate; or a portion of the first through hole is disposed in the first plate, and another portion of the first through hole is disposed in the second plate.

[0019] In this design, the first flow guide also includes a first through hole, and the first through hole enables the liquid to continue to flow downward through the first through hole.

[0020] The first through hole is arranged on the first plate, so that the liquid flowing through the first plate can continue to flow downward through the first through hole arranged on the first plate, avoiding the oil from solidifying on the first guide member, thereby reducing the frequency and difficulty of users cleaning the first guide member.

[0021] Part of the first through hole is arranged on the first plate, and the other part is arranged on the second plate, that is, the first through hole is arranged at the connecting position of the first plate and the second plate, which increases the flow area of ​​the first through hole and enables the liquid to flow downward through the first through hole more quickly.

[0022] In a possible design, the flow guide assembly further includes: a second flow guide member, the second flow guide member is respectively connected to the first flow guide member and the frame, and the second flow guide member is located below the first flow guide member.

[0023] In this design, the flow guide assembly also includes a second flow guide, which is arranged between the first flow guide and the frame. On the one hand, it plays a role in fixing the first flow guide to the frame, and on the other hand, the second flow guide and the first flow guide form an integrated flow guide structure, which enhances the effect of guiding the liquid. When the first flow guide is not cleaned for a long time and the flow guiding ability of the first flow guide is weakened, the second flow guide can continue to guide the liquid on the first flow guide, further reducing the frequency of cleaning of the oil fume treatment device by the user and improving the user experience.

[0024] In a possible design, the second guide member includes: a third plate member; a bending portion, which is arranged on the third plate member; and a second through hole, which is arranged on the bending portion.

[0025] In this design, the second flow guide comprises a third plate and a bent portion, and the bent portion is arranged on the third plate. The third plate with the bent portion can conduct secondary flow guidance on the liquid flowing through the first flow guide, thereby achieving secondary flow guidance on the liquid condensed on the grille, further preventing the liquid from flowing onto the outer wall of the oil fume treatment device.

[0026] In a possible design, the third plate is connected to the first plate and the frame respectively, and the distance between the bent portion and the first plate in the height direction ranges from greater than 2 mm to less than 7 mm.

[0027] In this design, the third plate is arranged between the first plate and the frame, and the third plate is lower than the first plate, so that the liquid flowing through the first plate can flow downward to the third plate under the influence of gravity. The distance between the bending portion of the third plate and the first plate in the height direction ranges from greater than 2 mm to less than 7 mm. The height difference is limited to greater than 2 mm, which can prevent the liquid level of the oil on the third plate from being higher than the height of the first plate. The height difference is limited to less than 7 mm, which can prevent the third plate from being too large, making it difficult for users to clean it.

[0028] It can be understood that the distance between the bending portion and the first plate in the height direction is preferably in the range of 3 mm to 4 mm.

[0029] In a possible design, the first through hole and the second through hole are staggered.

[0030] In this design, the first through hole and the second through hole are arranged in a staggered manner. When the liquid flows to the first guide member, the liquid can continue to flow downward through the first through hole. When the liquid flows through the first guide member and flows to the second guide member, the liquid can flow downward through the second through hole. The staggered arrangement of the first through hole and the second through hole can enable the liquid that has not flowed down from the first through hole to flow downward quickly from the second through hole, thereby improving the guiding effect of the guide component.

[0031] In a possible design, the guide assembly includes: a connecting member, which is arranged on the grille and is detachably connected to the first guide member.

[0032] In this design, the guide assembly further includes a connecting piece, which is arranged on the grille, and the first guide piece is connected to the grille via the connecting piece.

[0033] The connecting piece may be a pin, and a socket is provided on the first air guide. By inserting the pin on the grille into the socket, a stable installation of the grille is achieved.

[0034] In a possible design, the air guide assembly further includes: a support member, which is disposed on the frame and extends toward the air inlet, and the support member can support the grille.

[0035] In this design, the air guide assembly also includes a support member, which is arranged on the frame and extends toward the air inlet. The support member is arranged on two side edges of the frame to prevent the grille from falling off the frame.

[0036] In any of the above designs, two air inlets are provided.

[0037] According to the second aspect of the present invention, a fume treatment device is proposed, comprising: a body; a smoke guide channel, which is arranged in the body; a smoke baffle, which is arranged on the body; a flow guide assembly as in any of the above designs, the flow guide assembly is connected to the smoke baffle, and the flow guide assembly is configured to guide the fluid into the smoke guide channel, wherein the top surface of the smoke baffle is higher than the first flow guide member in the flow guide assembly along the gravity direction. Therefore, all the beneficial effects of any of the above flow guide assemblies are obtained, which will not be described in detail here.

[0038] The oil fume treatment device provided by the present invention includes a main body, a smoke guide channel, a smoke baffle and a flow guide assembly. The smoke guide channel is arranged inside the main body, the smoke baffle and the flow guide assembly are arranged on the main body, the frame in the flow guide assembly is connected to the smoke baffle, and the flow guide assembly is arranged above the smoke baffle. The smoke baffle is higher than the flow guide assembly, which can prevent the oil from flowing directly from the grille to the smoke baffle. When the oil fume treatment device is powered on and starts working, the gas carrying oil smoke flows into the smoke guide channel through the grille. In the process of the gas flowing through the grille, oil will condense on the grille. The oil on the grille flows downward due to the influence of gravity and is guided into the smoke guide channel by the flow guide assembly. The condensed oil can be prevented from flowing onto the smoke baffle, thereby reducing the frequency of the user cleaning the oil on the smoke baffle and improving the user experience.

After the oil flows through the guide component, it flows into the smoke guide channel through the guide plate. The guide plate can prevent the oil from sticking to the side wall of the smoke guide channel.

[0042] In a possible design, the oil fume treatment device also includes: a bellows, arranged in the main body, the bellows being connected to the smoke guide channel; a fan, arranged in the bellows; a lining plate, arranged in the smoke guide channel, the lining plate being configured to allow condensed oil stains to flow along the lining plate into the bellows.

[0066] In this embodiment, the guide assembly 100 includes a frame 120, a grille 180 and a first guide member 160. The frame 120 is provided with an air inlet 140. The grille 180 is embedded in the air inlet 140 of the frame 120. The grille 180 can guide the air flowing through the air inlet 140. The first guide member 160 is arranged on the frame 120. The first guide member 160 is located between the bottom surface of the grille 180 and the frame 120. The first guide member 160 and the grille 180 are arranged opposite to each other. The first guide member 160 can guide the liquid condensed on the grille 180 so that the condensed liquid can flow along the first guide member 160 to the oil fume channel of the oil fume treatment device 200, thereby preventing the condensed liquid from flowing from the frame 120 to the outer wall of the oil fume treatment device 200. The flow guide assembly 100 provided by the present invention not only guides the gas through the grille 180 so that the gas flowing through the grille 180 can enter the smoke guide channel 220 of the oil fume treatment device 200, but also guides the liquid condensed on the grille 180. Furthermore, by arranging the flow guide assembly 100 on the oil fume treatment device 200, the oil pollution condition of the oil fume treatment device 200 is improved, and the cleaning frequency and difficulty of the consumer are reduced.

[0067] It is understandable that the oil fume treatment device 200 can be selected as a side-suction range hood, or an integrated stove. When the oil fume treatment device 200 is in operation, air containing oil fume is sucked into the interior of the oil fume treatment device 200 through the grille 180, and the oil and water in the air will condense on the grille 180. The oil and water on the grille 180 flow through the first guide member 160 and flow into the interior of the oil fume treatment device 200. The interior of the oil fume treatment device 200 is also provided with an oil collecting box, which is specifically arranged in the smoke guiding channel 220 of the oil fume treatment device 200, and can guide the condensed oil and water. Figure 3 and Figure 4 As shown, the first flow guide 160 further includes: a first plate 162 and a second plate 164 connected to each other, and a positioning protrusion 166 , and an angle is set between the first plate 162 and the second plate 164 .

[0068] In this embodiment, the first guide member 160 includes a first plate 162 and a second plate 164. The first plate 162 is connected to the second plate 164. An angle is set between the first plate 162 and the second plate 164, so that the first plate 162 and the second plate 164 form a stepped structure. The first plate 162 can support the grille 180, so that the liquid condensed on the grille 180 flows downward to the first plate 162 and continues to flow downward from one side of the first plate 162. The second plate 164 connected to the first plate 162 can prevent the oil from flowing downward from the other side of the first plate 162, thereby achieving a liquid diversion effect on the first guide member 160.

[0069] In any of the above embodiments, the angle between the first plate 162 and the second plate 164 is greater than or equal to 90° and less than or equal to 180°, the first plate 162 is connected to the frame 120, and the first plate 162 extends into the air inlet 140 along the air inlet direction. The positioning protrusion 166 is integrally formed on the first plate 162. In this embodiment, the angle between the first plate 162 and the second plate 164 is set to be greater than or equal to 90° and less than or equal to 180°, which can effectively prevent the grille 180 from falling off from the first guide member 160, thereby enhancing the stability of the installation of the grille 180.

[0070] In a specific embodiment, the first plate 162 and the second plate 164 are integrally formed. The angle between the first plate 162 and the second plate 164 is selected to be 90°, and at least part of the first plate 162 and the second plate 164 is an arc-shaped bent plate, and the connection formed by the arc-shaped bent plates of the first plate 162 and the second plate 164 is an arc.

[0071] Setting the connection as an arc chamfer can allow the oil to flow smoothly through the connection between the first plate 162 and the second plate 164, avoiding dirt and grime, and making it easy for the user to clean the first guide member 160.

[0073] In another specific embodiment, the first plate member 162 and the second plate member 164 are connected by bolts, the angle between the first plate member 162 and the second plate member 164 is 140°, and the first plate member 162 and the second plate member 164 are inclined plates.

[0074] like Figure 4As shown, in any of the above embodiments, the first guide member 160 also includes a positioning protrusion 166, which is arranged on the first plate 162. The positioning protrusion 166 contacts and abuts against the grille 180, so that a certain gap is formed between the grille 180 and the frame 120, so that the liquid left on the grille 180 can continue to flow downward through the gap, thereby improving the effect of the guide assembly 100 on liquid diversion, thereby avoiding oil spillage.

[0075] The distance between the highest point of the positioning protrusion 166 and the first plate 162 along the gravity direction is greater than or equal to 1 mm and less than or equal to 10 mm. By limiting the height of the positioning protrusion 166, the width of the gap between the grille 180 and the frame 120 is limited, so that the gap between the grille 180 and the frame 120 is greater than or equal to 1 mm, and the oil flowing through the gap can continue to flow downward, thereby avoiding the gap from being blocked. The gap between the grille 180 and the frame 120 is less than or equal to 10 mm, which can improve the installation stability of the grille 180 and the frame 120 and prevent the grille 180 from falling off the frame 120.

[0076] In the above embodiment, the first flow guide 160 further includes a first through hole 168 .

[0077] In this embodiment, the first through hole 168 enables the liquid to continue to flow downward through the first through hole 168 .

[0078] In a specific embodiment, the first through hole 168 is disposed in the first plate 162 .

[0079] In this embodiment, the first through hole 168 is arranged on the first plate 162, so that the liquid flowing through the first plate 162 can continue to flow downward through the first through hole 168 arranged on the first plate 162, thereby preventing the oil from solidifying on the first guide member 160, thereby reducing the frequency and difficulty of the user's cleaning of the first guide member 160.

[0080] like Figure 2 As shown, in another specific embodiment, a portion of the first through hole 168 is disposed on the first plate 162 , and another portion of the first through hole 168 is disposed on the second plate 164 .

[0081] In this embodiment, a portion of the first through hole 168 is arranged on the first plate 162, and the other portion is arranged on the second plate 164, that is, the first through hole 168 is arranged at the connecting position between the first plate 162 and the second plate 164, which increases the flow area of ​​the first through hole 168 and enables the liquid to flow downward through the first through hole 168 more quickly.

[0082] In any of the above embodiments, the grille 180 is arranged at an incline.

[0083] In this embodiment, the oil condensed on the grid 180 flows along the grid to the first guide member 160 under the action of gravity, and the condensed oil is guided by the first guide member 160 .

On the one hand, it plays a role in fixing the first flow guide 160 to the frame 120, and on the other hand, the second flow guide 170 and the first flow guide 160 form an integral flow guide structure, thereby enhancing the effect of guiding the liquid. When the first flow guide 160 is not cleaned for a long time and the flow guiding ability of the first flow guide 160 is weakened, the second flow guide 170 can continue to guide the liquid on the first flow guide 160, thereby further reducing the frequency of cleaning of the oil fume treatment device 200 by the user and improving the user's experience.

[0091] like Figure 8 As shown, the first plate 162, the second plate 164, the third plate 172 and the frame 120 are integrally formed, which saves processing steps and eliminates difficult-to-clean gaps between the first plate 162, the second plate 164, the third plate 172 and the frame 120, thereby improving the user experience.

[0092] In this embodiment, the second guide member 170 includes a third plate member 172 and a bent portion 174, and the bent portion 174 is disposed on the third plate member 172.

[0093] The third plate 172 is disposed between the first plate 162 and the frame 120, and the third plate 172 is lower than the first plate 162, so that the liquid flowing through the first plate 162 can flow downward to the third plate 172 under the influence of gravity. The distance between the bending portion 174 of the third plate 172 and the first plate 162 in the height direction ranges from greater than 2 mm to less than 7 mm. The height difference is limited to greater than 2 mm, which can prevent the liquid level of the oil on the third plate 172 from being higher than the height of the first plate 162. The height difference is limited to less than 7 mm, which can prevent the third plate 172 from being too large, making it easier for the user to clean the second guide member 170.

[0094] Furthermore, the distance between the bending portion 174 and the first plate 162 in the height direction is preferably in the range of 3 mm to 4 mm.

[0095] In any of the above embodiments, the first through hole 168 is disposed on the first flow guide 160 , and the first through hole 168 and the second through hole 176 are staggered.

[0096] In this embodiment, the first through hole 168 and the second through hole 176 are arranged in a staggered manner. When the liquid flows to the first guide member 160, the liquid can continue to flow downward through the first through hole 168. When the liquid flows through the first guide member 160 and flows to the second guide member 170, the liquid can flow downward through the second through hole 176. The staggered arrangement of the first through hole 168 and the second through hole 176 can enable the liquid that has not flowed down from the first through hole 168 to flow downward from the second through hole 176 quickly, thereby improving the guiding effect of the guide assembly 100.

[0097] In any of the above embodiments, the guide assembly 100 includes: a connecting member and a supporting member 190 , the connecting member is arranged on the frame 120 , the supporting member 190 is arranged on the frame 120 , and the supporting member 190 and the connecting member are located between the frame 120 and the grille 180 .

[0098] In this embodiment, the air guide assembly 100 further includes a support member 190, which is disposed on the frame 120 and extends toward the air inlet 140. The support member 190 is disposed on two side edges in the frame 120, so as to prevent the grille 180 from falling off from the frame 120. A connecting member is disposed on the grille 180, and the first air guide 160 is connected to the grille 180 through the connecting member. The connecting member may be a pin, and a socket is disposed on the first air guide 160. By inserting the pin on the grille 180 into the socket, the grille 180 is stably installed.

[0099] Embodiment three:

[0100] like Figure 3 As shown, an embodiment of the present invention provides an oil fume treatment device 200, comprising: a body 210; a smoke guide channel 220, which is arranged in the body 210; a smoke baffle 230, which is arranged on the body 210; as the guide assembly 100 in the above-mentioned embodiment 1 and / or embodiment 2, the guide assembly 100 is connected to the smoke baffle 230, and the guide assembly 100 is configured to guide the fluid into the smoke guide channel 220, wherein the top surface of the smoke baffle 230 is higher than the first guide member 160 in the guide assembly 100 along the gravity direction. Therefore, all the beneficial effects of the above-mentioned embodiment 1 and embodiment 2 are obtained, which will not be repeated here.

[0101] In this embodiment, the oil fume treatment device 200 includes a body 210, a smoke guide channel 220, a smoke baffle 230 and a flow guide assembly 100. The smoke guide channel 220 is arranged inside the body 210, the smoke baffle 230 and the flow guide assembly 100 are arranged on the body 210, the frame 120 in the flow guide assembly 100 is connected to the smoke baffle 230, and the flow guide assembly 100 is arranged above the smoke baffle 230. The smoke baffle 230 is higher than the flow guide assembly 100, which can prevent the oil from flowing directly from the grille 180 to the smoke baffle 230. When the oil fume treatment device 200 is powered on and starts working, the gas with oil fume flows into the smoke guide channel 220 through the grille 180. In the process of the gas flowing through the grille 180, oil will condense on the grille 180, and the oil on the grille 180 will flow downward under the influence of gravity and be guided to the smoke guide channel 220 by the flow guide assembly 100. The condensed oil can be prevented from flowing onto the smoke baffle 230 , thereby reducing the frequency of the user cleaning the oil on the smoke baffle 230 and improving the user experience.

[0102] like Fig.10 As shown, in the above embodiment, the oil fume treatment device 200 also includes: a guide plate 260 arranged in the smoke guide channel 220, the guide plate 260 is connected to the guide assembly 100, and the guide plate 260 can change the flow direction of the oil flowing through the guide plate 260.

[0103] In this embodiment, the oil fume treatment device 200 also includes a guide plate 260, which is arranged in the smoke guide channel 220. The guide plate 260 is connected to the guide component 100. After the oil flows through the guide component 100, it flows into the smoke guide channel 220 through the guide plate 260. The guide plate 260 can prevent the oil from sticking to the side wall of the smoke guide channel 220.

[0104] In the above embodiment, the guide plate 260 is provided with a guide bevel 262, and the guide bevel 262 has an inclination angle relative to the guide plate 260, and the inclination angle ranges from 8° to 45°. The length of the guide bevel in the height direction is greater than 1 mm and less than 5 mm.

[0105] The guiding bevel 262 can further guide the oil flowing through the guide plate 260 , thereby preventing the oil from solidifying in the smoke guiding channel 220 .

[0106] In any of the above embodiments, the oil fume treatment device 200 also includes: a bellows 250 arranged in the main body 210, a fan arranged in the bellows 250 and a lining plate 240 arranged in the smoke guide channel 220, the bellows 250 is connected to the smoke guide channel 220, and the lining plate 240 is capable of allowing condensed oil stains to flow along the lining plate 240 into the bellows 250.

[0107] In this embodiment, the oil fume treatment device 200 also includes a bellows 250, a fan and a lining plate 240. The fan is arranged in the bellows 250. When the fan is working, it can drive external air to flow into the smoke guide channel 220. The lining plate 240 is detachably arranged in the smoke guide channel 220, so that the oil can flow downward in the smoke guide channel 220 along the lining plate 240.

[0108] In any of the above embodiments, the oil fume treatment device 200 further includes an oil receiving box, and an inlet of the oil receiving box is connected to the lining plate 240 .

[0109] In this embodiment, the oil flowing through the lining plate 240 can flow into the oil collecting box through the inlet of the oil collecting box. The oil collecting box is detachably connected in the smoke guiding channel 220. When the oil collecting box is full, the user can take out the oil collecting box for cleaning.

[0110] Among them, the oil fume treatment device 200 includes a range hood and an integrated stove.

[0111] like Fig. 9 As shown, the rising oil smoke flows through the grille 180 under the negative pressure generated by the fan, and liquefies on the grille 180 after condensation. When the fan is turned on, the oil flows down along the flange of the grille 180 under the action of the fan and gravity, converges at the bottom inner edge of the grille 180, and is sucked into the smoke guide duct through the first through hole 168 under the action of wind. At the same time, the unseparated oil hits the inside of the head flue and is introduced into the chassis along the liner 240. When the fan is turned off, especially for a moment, the oil on the grille 180 suddenly loses the fan pulling force under the action of wind, and at the same time, under the action of the gravity of the oil, it flows to the outside of the bottom of the grille 180 and flows out of the oil net along the outer surface of the grille 180. It flows to the first guide member 160. Since the height of the smoke baffle 230 is higher than the second guide member 170 of the guide assembly 100, and since there is a gap of 3 mm to 4 mm here, the oil stains flow into the bellows 250 through the second through hole 176 of the second guide member 170. The oil flowing into the bellows 250 can reduce the oil stains on the liner 240 under the action of the oil guide of the guide plate 260, thereby reducing the oil stain cleaning work here. The oil guide of the liner 240 can guide the oil stains behind the liner 240 generated by the airflow collision of the liner 240 into the interior of the bellows 250. When the first through hole 168 is blocked and becomes ineffective due to solidification after being used for a long time without being cleaned, the oil can also be discharged through the second through hole 176, thereby eliminating the oil climbing phenomenon of the smoke baffle 230, and reducing the frequency of the user's cleaning of the oil fume treatment device 200. The user experience is improved.
