[0054] Embodiment 1

[0055] As shown Figures 1 to 9 in the figure, this embodiment provides an oil fume treatment device 100, which can be an oil fume extractor, an integrated stove, etc. In this embodiment, an oil fume extractor is taken as an example for illustration. The oil fume extractor includes a main chassis 60 and a smoke collecting cavity mechanism 20. The smoke collecting cavity mechanism 20 is arranged at the lower end of the main chassis 60 and is communicated with the inside of the main chassis 60. As shown Figure 1 and Figure 2 in the figure, the smoke collecting cavity mechanism 20 includes a smoke collecting hood 21. The smoke collecting hood 21 includes a bottom plate 211, a front side plate assembly 212, a rear side plate 213, a left side plate 214, a right side plate 215 and an upper end plate 216. The front side plate assembly 212, the left side plate 214, the rear side plate 213 and the right side plate 215 are sequentially connected. The front side plate assembly 212 and the rear side plate 213 are arranged at intervals in the front-rear direction, and the left side plate 214 and the right side plate 215 are arranged in the left-right direction. The front side plate assembly 212, the left side plate 214, the rear side plate 213 and the right side plate 215 together form a cavity space. The cavity space includes an upper opening and a lower opening. The upper end plate 216 is located at the upper opening, and the bottom plate 211 is located at the lower opening.

[0056] In an alternative embodiment, as shown Figure 3 in the figure, the front side plate assembly 212 includes a front side plate 2121 and a front side support member 2122. Among them, the front side plate 2121, the left side plate 214, the rear side plate 213 and the right side plate 215 are sequentially fixedly connected. The front side support member 2122 is arranged inside the front side plate 2121. By arranging the front side support member 2122, the strength and hardness of the front side plate assembly 212 can be improved.

[0057] As shown Figure 1 and Figure 2 in the figure, the bottom plate 211 is provided with a first inner concave cavity 2111 and a second inner concave cavity 2112. The first inner concave cavity 2111 and the second inner concave cavity 2112 are arranged in the left-right direction. A first smoke inlet 21111 is opened on the bottom wall of the first inner concave cavity 2111, and a second smoke inlet 21121 is opened on the bottom wall of the second inner concave cavity 2112. When the main chassis 60 works, the fan inside the main chassis 60 rotates to form a negative pressure area. The oil fume outside the oil fume extractor can enter the main chassis 60 after passing through the two inner concave cavities and the two smoke inlets in sequence. The oil fume is filtered inside the main chassis 60 and then discharged to the outside of the main chassis 60.

[0058] In an alternative embodiment, it can also be that only one first inner concave cavity 2111 is opened on the bottom plate 211. In an alternative embodiment, three, four or more smoke inlets can also be opened on the bottom plate 211.

[0059] As shown Figure 1 and Figure 2As shown, the range hood further includes a smoke baffle assembly. The smoke baffle assembly includes a first smoke baffle 30 and a second smoke baffle 40. Among them, the first smoke baffle 30 corresponds to the first smoke inlet 21111, and the second smoke baffle 40 corresponds to the second smoke inlet 21121. The first smoke baffle 30 can be selectively switched between a first position where the first smoke inlet 21111 is opened and a second position where the first smoke inlet 21111 is blocked. The second smoke baffle 40 is switched between a third position where the second smoke inlet 21121 is opened and a fourth position where the second smoke inlet 21121 is blocked. The open or blocked states of the first smoke inlet 21111 and the second smoke inlet 21121 can be adaptively adjusted according to the specific situation of the oil fume. It should be noted that the smoke baffle assembly may also include only one smoke baffle, or may include three, four or more smoke baffles.

[0060] In an alternative embodiment, as Figure 1 shown, the range hood further includes an oil cup 70. The oil cup 70 is arranged at the lower end of the smoke collecting cavity mechanism 20, and the dirty oil inside the smoke collecting cavity mechanism 20 can flow into the oil cup 70 for storage.

[0061] As Figures 2 to 4 shown, the range hood further includes a driving device 10. The driving device 10 is used to make the first smoke baffle 30 and the second smoke baffle 40 move synchronously, so that each smoke baffle is switched between a position where the corresponding smoke inlet is blocked and a position where the corresponding smoke inlet is opened.

[0062] However, the existing driving device 10 is directly installed on the smoke collecting hood 21. The smoke collecting hood 21 is mainly a plate structure and the smoke collecting hood 21 is a hollow structure inside. And the driving device 10 is usually arranged at the middle position of the hollow structure, which is not convenient for the installation and connection of the driving device 10 and the smoke collecting hood 21.

[0063] To solve the above problems, as Figures 2 to 4 shown, the range hood further includes an installation mechanism 80. The installation mechanism 80 is fixedly connected to the smoke collecting cavity mechanism 20. The driving device 10 is arranged on the installation mechanism 80. On the one hand, the installation mechanism 80 can be better connected to the smoke collecting cavity mechanism 20. On the other hand, the installation mechanism 80 can also have better support for the driving device 10. Through the setting of the installation mechanism 80, it is convenient for the driving device 10 to be better installed and connected to the smoke collecting cavity mechanism 20.

[0064] In an alternative embodiment, as Figure 2 shown, the smoke collecting cavity mechanism 20 further includes a support frame 22. The support frame 22 is arranged inside the smoke collecting hood 21 and is fixedly connected to the smoke collecting hood 21. Through the setting of the support frame 22, the strength and hardness of the smoke collecting cavity mechanism 20 can be effectively improved, so as to realize the stable supporting effect of the smoke collecting cavity mechanism 20 on the installation mechanism 80 and the driving device 10. As Figure 2As shown, the support frame 22 includes one, two or more connecting rods. One end of the support frame 22 is fixedly connected to the front side plate assembly 212, and the other end of the support frame 22 is fixedly connected to the rear side plate 213. Through the arrangement of a number of support frames 22, on the premise of saving space, a significant improvement in the smoke collecting cavity mechanism 20 can be achieved. In addition, the structure of the support frame 22 is simple, which is convenient to achieve a quick and stable connection effect between the support frame 22 and the smoke collecting cavity mechanism 20.

[0065] In an alternative embodiment, as Figures 2 to 4 shown, the mounting mechanism 80 can be fixedly connected to the front side plate assembly 212, the rear side plate 213 and the support frame 22 respectively. Since different positions of the smoke collecting cavity mechanism 20 are fixedly connected to the mounting mechanism 80, a good stable support effect of the smoke collecting cavity mechanism 20 on the mounting mechanism 80 and the driving device 10 can be achieved.

[0066] In an alternative embodiment, the mounting mechanism 80 can also be fixedly connected to at least one of the front side plate assembly 212, the rear side plate 213 and the support frame 22, and a good connection and fixing effect between the mounting mechanism 80 and the smoke collecting cavity mechanism 20 can also be achieved.

[0067] In an alternative embodiment, as Figure 2 shown, the rear side plate 213 includes a rear side plate body 2131 and a reinforcing member 2132. The reinforcing member 2132 is arranged on the rear side plate body 2131 to improve the strength and hardness of the rear side plate 213, and further strengthen the stable support effect of the smoke collecting cavity mechanism 20 on the driving device 10 and the main chassis 60.

[0068] In an alternative embodiment, the bottom plate 211, the front side plate assembly 212, the left side plate 214, the right side plate 215, the upper end plate 216, etc. can also adopt a similar structure to the aforementioned rear side plate 213, and a further strengthened stable support effect of the smoke collecting cavity mechanism 20 on the driving device 10 and the main chassis 60 can also be achieved.

[0069] As Figures 3 to 5 shown, the mounting mechanism 80 includes a plurality of connecting beams 811. The plurality of connecting beams 811 together form a receiving space 84. At least part of the driving device 10 is received in the receiving space 84. While ensuring good strength of the mounting mechanism 80, a compact arrangement of the mounting mechanism 80 and the driving device 10 can also be achieved, and a reasonable placement of the mounting mechanism 80 and the driving device 10 can be realized in the limited space within the smoke collecting hood 21, achieving a reasonable utilization of the limited space.

[0070] It should be noted that two adjacent connecting beams 811 can be fixed by various methods such as welding, pin fixing, screw fixing, and snap fixing, all of which can achieve the stable connection of two adjacent connecting beams 811. In an alternative embodiment, multiple connecting beams 811 can be formed by bending a whole cross beam, which has a simple structure and is easy to manufacture. The connection position of two adjacent connecting beams 811 can undergo plastic deformation to produce work hardening effect, which can further improve the strength and hardness of the installation mechanism 80.

[0071] In an alternative embodiment, as Figure 5 shown, the connecting beam 811 includes a connecting plate 8111 and a reinforcing plate 8112. The reinforcing plate 8112 extends from one side of the connecting plate 8111, and the connecting plate 8111 and the reinforcing plate 8112 are arranged at an angle. By providing the reinforcing plate 8112, the strength and hardness of the connecting beam 811 can be effectively improved, thereby effectively improving the strength and hardness of the installation mechanism 80, and realizing the stable supporting effect of the installation mechanism 80 on the driving device 10. It should be noted that the reinforcing plate 8112 and the connecting plate 8111 can be formed by bending a whole plate, which is convenient for the rapid manufacture of the connecting beam 811. Due to being processed and manufactured by the bending process, the connection position of the reinforcing plate 8112 and the connecting plate 8111 can undergo plastic deformation to produce work hardening effect, which can further improve the strength and hardness of the connecting beam 811 and the installation mechanism 80.

[0072] In an alternative embodiment, the connecting plate 8111 and the reinforcing plate 8112 can achieve a good fixing effect by means such as welding, screw fixing, pin fixing, and snap component fixing.

[0073] Combined with Figures 2 to 4 、 Figure 6 and Figure 7 shown, the driving device 10 includes at least two driving mechanisms 11. Each driving mechanism 11 can independently drive the corresponding smoke baffle, and each smoke baffle is independently controlled by the corresponding driving mechanism 11, which can realize the flexible control of each smoke baffle.

[0074] In an alternative embodiment, combined with Figures 2 to 5As shown, the driving mechanism 11 includes a first body 115 and a first output end 116 capable of moving linearly relative to the first body 115. The first body 115 can be pivotally connected to the mounting mechanism 80 about the front-rear direction (i.e., the extending direction of the first axis). The first output end 116 is fixedly connected to the first smoke baffle 30. The first smoke baffle 30 includes a first baffle body 32 and a first rotating shaft 31 provided thereon. The first rotating shaft 31 extends in the front-rear direction (i.e., the extending direction of the third axis). A guiding groove 831 is formed in the mounting mechanism 80. The first rotating shaft 31 is inserted into the guiding groove 831, and the extending direction of the guiding groove 831 is perpendicular to the front-rear direction. When the first output end 116 moves linearly relative to the first body 115, the first output end 116 drives the first rotating shaft 31 to slide along the guiding groove 831, and the first body 115 rotates relative to the mounting mechanism 80 about the front-rear direction, thereby realizing the complex curvilinear motion path of the rotation and movement of the first baffle body 32 relative to the smoke collecting hood 21. When the first smoke baffle 30 is in the state of opening the first smoke inlet 21111, the outer contour edges of the first smoke baffle 30 are all spaced from the smoke collecting hood 21. That is to say, smoke can enter from all circumferential directions of the first smoke baffle 30, which can further improve the smoke extraction effect of the range hood compared with the first baffle body 32 that can only perform a single flipping motion.

[0075] In an alternative embodiment, as Figure 4 and Figure 5 shown, the mounting mechanism 80 includes a mounting main body 81 and a first mounting plate 82. The mounting main body 81 is fixedly connected to the smoke collecting cavity mechanism 20. The first mounting plate 82 is arranged on the mounting main body 81. The first body 115 is pivotally connected to the first mounting plate 82. Through the arrangement of the first mounting plate 82, it is convenient for the quick assembly of the first body 115 and the mounting mechanism 80. Exemplarily, the first body 115 can be connected to the first mounting plate 82 through a pivot shaft, wherein the pivot shaft extends in the front-rear direction.

[0076] In an alternative embodiment, as Figure 4 and Figure 5 shown, the mounting mechanism 80 further includes a second mounting plate 83. The second mounting plate 83 is arranged on the mounting main body 81. The guiding groove 831 is formed in the second mounting plate 83. Through the arrangement of the second mounting plate 83, it is convenient for the quick assembly of the first rotating shaft 31 and the guiding groove 831. Exemplarily, the second mounting plate 83 can be provided as one, two, three or more. When the second mounting plate 83 is one, the overall structure of the range hood is simple; when the second mounting plate 83 is at least two, at least two second mounting plates 83 are arranged at intervals in the front-rear direction, and at least two second mounting plates 83 jointly support the first rotating shaft 31, and at least two second mounting plates 83 can achieve a relatively stable supporting effect on the first rotating shaft 31.

[0077] In an alternative embodiment, the structure of the second smoke baffle 40 is the same as or similar to that of the first smoke baffle 30, and the connection manner between the second smoke baffle 40 and the installation mechanism 80 is the same as or similar to the connection manner between the first smoke baffle 30 and the installation mechanism 80.

[0078] In an alternative embodiment, as Figure 4 shown, the first smoke baffle 30 may further include a support plate 33. The support plate 33 is disposed on the first baffle body 32, and the first output end 116 is fixedly connected to the support plate 33, facilitating the quick and stable assembly of the first output end 116 and the support plate 33.

[0079] In an alternative embodiment, the drive mechanism 11 includes a first body 115 and an output end capable of moving linearly relative to the first body 115. The first body 115 is pivotally connected to the installation mechanism 80 about the front-rear direction (i.e., the extending direction of the first axis), the output end is pivotally connected to the first smoke baffle 30 about the front-rear direction (i.e., the extending direction of the second axis), and the first smoke baffle 30 is pivotally connected to the smoke collecting cavity mechanism 20 about the front-rear direction (i.e., the extending direction of the third axis). When the output end moves linearly relative to the first body 115, the first body 115 can rotate relative to the installation mechanism 80, and the output end can push the first smoke baffle 30 to rotate relative to the installation mechanism 80 about the front-rear direction, thereby realizing the position switching of the drive mechanism 11 for the first smoke baffle 30. The connection manner between the drive mechanism 11 and the first smoke baffle 30 in this embodiment is simpler than the connection manner between the drive mechanism 11 and the first smoke baffle 30 mentioned in the foregoing embodiment. The related structure of this alternative embodiment is simpler, facilitating the quick assembly of the drive mechanism 11 and the installation mechanism 80 by the operator.

[0080] Embodiment Two

[0081] The range hood disclosed in Embodiment One needs to drive at least two smoke baffles to move by setting at least two sets of drive mechanisms 11. The number of drive mechanisms 11 that need to be set in the range hood of Embodiment One is relatively large. The overall volume of at least two sets of drive mechanisms 11 is relatively large, the structure is relatively complex, the energy consumption is relatively high, and the control method is relatively complex.

[0082] To solve the above problems, the present disclosure discloses a range hood in this embodiment. The structure of the range hood in this embodiment of the present disclosure is basically the same as that of the range hood in Embodiment One. The main difference between the two is the setting form of the drive device 10.

[0083] As Figure 8 and Figure 9As shown in the figure, the driving device 10 of the present disclosure embodiment includes a driving mechanism 11 and a transmission assembly 12. At least two smoke baffle plates are drivingly connected to the driving mechanism 11 through the transmission assembly 12, and the driving mechanism 11 can synchronously flip at least two smoke baffle plates through the transmission assembly 12. Only one set of driving mechanism 11 is provided in the present disclosure embodiment to achieve synchronous flipping of at least two smoke baffle plates. Compared with the two sets of driving mechanisms 11 in Embodiment 1, the driving device 10 of the present disclosure embodiment has a relatively smaller volume, a relatively simpler structure, relatively lower energy consumption, and a relatively simpler control method.

[0084] In an alternative embodiment, as Figure 8 and Figure 9 shown, the smoke baffle plate includes a first smoke baffle plate 30 and a second smoke baffle plate 40. The first smoke baffle plate 30 and the second smoke baffle plate 40 are symmetrically arranged. The center line of the driving device 10 coincides with the symmetry line of the first smoke baffle plate 30 and the second smoke baffle plate 40, which is convenient for the driving device 10 to synchronously drive the first smoke baffle plate 30 and the second smoke baffle plate 40, and realizes a reasonable layout of the driving device 10, the first smoke baffle plate 30, and the second smoke baffle plate 40 in a limited space.

[0085] In an alternative embodiment, as Figure 8 and Figure 9 shown, the driving mechanism 11 includes a second body 111 and a second output end 112 that can move relative to it in the up and down direction (i.e., the first direction). The second body 111 is arranged on the mounting mechanism 80. The second output end 112 is drivingly connected to the first smoke baffle plate 30 and the second smoke baffle plate 40 through the transmission assembly 12 respectively. Through the simple linear motion of the second output end 112 relative to the second body 111, synchronous flipping of the first smoke baffle plate 30 and the second smoke baffle plate 40 can be achieved. The structure of the driving mechanism 11 is simple and convenient for installation. Specifically, the driving mechanism 11 can be a linear output driving mechanism. The linear output driving mechanism can be a linear output motor, a linear output cylinder, a linear guide rail, etc. It can also be a motor cooperating with a gear-rack assembly, or a motor cooperating with a multi-link assembly, or a motor cooperating with a crank-slider structure, etc. All structures or components that can achieve linear motion output are within the protection scope of this alternative embodiment.

[0086] In an alternative embodiment, as Figure 8 and Figure 9 shown, the transmission assembly 12 includes a mounting member 121, a first connecting rod 122, and a second connecting rod 123. The mounting member 121 is fixedly connected to the second output end 112. One end of the first connecting rod 122 is rotatably connected to the mounting member 121, and the other end of the first connecting rod 122 is rotatably connected to the first smoke baffle plate 30. One end of the second connecting rod 123 is rotatably connected to the mounting member 121, and the other end of the second connecting rod 123 is rotatably connected to the second smoke baffle plate 40.

[0087] If the setting position of the second output end 112 is at the upper end of the second body 111, when the second output end 112 is at a low position, the first smoke baffle 30 opens the first air inlet 21111, and when the second output end 112 is at a high position, the second smoke baffle 40 opens the second air inlet 21121. When the second output end 112 moves upward, that is, from Figure 8 state to Figure 9 state, the second output end 112 simultaneously drives the first hinge point of the first connecting rod 122 and the second hinge point of the second connecting rod 123 to move upward at the same time. The first connecting rod 122 and the second connecting rod 123 rotate around their respective hinge points, and the first connecting rod 122 and the second connecting rod 123 rotate in a trend of approaching each other. At the same time, the first connecting rod 122 drives the first smoke baffle 30 to rotate clockwise so that the first smoke baffle 30 closes and seals the first air inlet 21111, and the second connecting rod 123 drives the second smoke baffle 40 to rotate counterclockwise so that the second smoke baffle 40 closes and seals the second air inlet 21121. Through the up-and-down movement of the second output end 112, the synchronous opening or sealing of the first air inlet 21111 and the second air inlet 21121 is realized. By adjusting the position and stroke of the second output end 112, the opening and closing angles of the first smoke baffle 30 and the second smoke baffle 40 are adjusted, so that the air inflow rates of the first air inlet 21111 and the second air inlet 21121 can be adjusted. In an optional embodiment, the second output end 112 can also be arranged at the lower end of the second body 111, and the above technical effects can also be achieved.

[0088] In an optional embodiment, as Figure 8 and Figure 9 shown, the range hood further includes a guiding mechanism 50. The guiding mechanism 50 is arranged between the mounting member 121 and the mounting mechanism 80. The guiding mechanism 50 is used to make the mounting member 121 move in the up-and-down direction without deflection, so as to realize the precise driving of the first smoke baffle 30 and the second smoke baffle 40.

[0089] In an optional embodiment, as Figure 8 and Figure 9 shown, the guiding mechanism 50 includes a guide rail 51 and a third slider 52. The guide rail 51 extends in the up-and-down direction and is fixedly connected to the mounting mechanism 80. The third slider 52 is fixedly connected to the mounting member 121 and can slide along the guide rail 51. Through the cooperation of the guide rail 51 and the third slider 52, the precise guiding effect of the mounting member 121 moving in the up-and-down direction can be realized.

[0090] In an optional embodiment, the guiding mechanism 50 is set to at least two, and two of the guiding mechanisms 50 are arranged in the front-back direction. By setting at least two guiding mechanisms 50, the mounting member 121 can be prevented from rotating during the up-and-down movement.

[0091] Since the smoke collecting hood 21 is very thin, it is not easy to place a relatively large driving device 10 inside the smoke collecting hood 21. In an alternative embodiment, as Figure 8 and Figure 9 shown, the driving device 10 is located between the first smoke inlet 21111 and the second smoke inlet 21121. The driving device 10 is located inside the main chassis 60, effectively accommodating the driving device 10 by reasonably utilizing the space at the connection position between the main chassis 60 and the smoke collecting hood 21. The main chassis 60 can completely shield the driving device 10, and the overall shape of the range hood is more beautiful.

[0092] In an alternative embodiment, of course, part or all of the driving device 10 can also be arranged outside the main chassis 60, which is convenient for users to check and maintain the state of the driving device 10.

[0093] Embodiment III

[0094] The present disclosure embodiment discloses an oil fume treatment device 100. The structure of the oil fume treatment device 100 is basically the same as that of the oil fume treatment device 100 in Embodiment II. The main difference between the two is that as Figure 10 and Figure 11 shown, the structure of the transmission assembly 12 is different. Specifically, the transmission assembly 12 includes a mounting member 121, a connecting member 124, a first connecting rod 122, a first slider 125, a second connecting rod 123, and a second slider 126. The mounting member 121 is fixedly connected to the mounting mechanism 80, the connecting member 124 is fixedly connected to the second output end 112. One end of the first connecting rod 122 is rotatably connected to the first slider 125. The first slider 125 can slide relative to the connecting member 124 in the left-right direction (i.e., the second direction). The other end of the first connecting rod 122 is fixedly connected to the first smoke baffle 30. The middle of the first connecting rod 122 is rotatably connected to the mounting member 121. One end of the second connecting rod 123 is rotatably connected to the second slider 126. The second slider 126 can slide relative to the connecting member 124 in the left-right direction. The other end of the second connecting rod 123 is fixedly connected to the second smoke baffle 40. The middle of the second connecting rod 123 is rotatably connected to the mounting mechanism 80. Through this transmission assembly 12, it is also possible to achieve the synchronous flipping of the first smoke baffle 30 and the second smoke baffle 40 with only one set of driving mechanisms 11. Compared with the two sets of driving mechanisms 11 in Embodiment I, the driving device 10 in the present disclosure embodiment has a smaller volume, a simpler structure, lower energy consumption, and a simpler control method.

[0095] Specifically, as Figure 10 and Figure 11As shown, the connecting member 124 includes a connecting member body 1241 and a sliding rail 1242 that are fixedly connected. The connecting member body 1241 is fixedly connected to the second output end 112. The sliding rail 1242 extends in the left-right direction. The first slider 125 and the second slider 126 are arranged on the sliding rail 1242 and can slide along the sliding rail 1242. The sliding rail 1242 can achieve a good guiding effect on the first slider 125 and the second slider 126.

[0096] Embodiment Four

[0097] An embodiment of the present disclosure discloses an oil fume treatment device 100. The structure of the oil fume treatment device 100 is basically the same as that of the oil fume treatment device 100 in Embodiment Two. The main difference between the two is that, as Figure 12 shown, the structure of the transmission assembly 12 is different. Specifically, the driving mechanism 11 is a motor. The motor includes a third body 113 and a third output end 114 that can rotate relative to it. The transmission assembly 12 includes a first gear 127 and a second gear 128 that are engaged with each other. The first smoke baffle 30 includes a first rotating shaft 31 and a first baffle body 32 that are fixedly connected. The first rotating shaft 31 is rotatably connected to the mounting mechanism 80. The second smoke baffle 40 includes a second rotating shaft and a second baffle body that are fixedly connected. The second rotating shaft is rotatably connected to the mounting mechanism 80. The first gear 127 is coaxially fixed to the first rotating shaft 31, and the second gear 128 is coaxially fixed to the second rotating shaft. The first rotating shaft 31 is coaxially fixed to the third output end 114. When the motor works, the third output end 114 drives the first rotating shaft 31 and the first baffle body 32 to rotate. Under the transmission action of the first gear 127 and the second gear 128, the second rotating shaft and the second baffle body can be synchronously flipped. The cooperation of the first gear 127 and the second gear 128 has high reliability, large load-bearing capacity, long service life and strong adaptability.

[0098] In an alternative embodiment, it can also be that the third output end 114 is coaxially fixed to the second rotating shaft, and the above effects can also be achieved.

[0099] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, and are not limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here.
