[0054] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0055] like Figures 1 to 10 As shown in the figure, this disclosure provides a waste oil packaging device and a range hood for use in range hoods. The drive component can drive the recycling bag 20 to move to the oil leakage port so that the recycling bag 20 can collect the waste oil, thereby realizing automatic waste oil recycling. After the waste oil recycling is completed, the user can directly remove the recycling bag 20, making the operation simpler and the user experience better.

[0056] like Figures 1 to 10 As shown, this embodiment of the present disclosure provides a waste oil baling device for a range hood. The range hood includes a housing 10 and a recycling bag 20. The housing 10 includes an oil collection tank with an oil drain outlet, and the recycling bag 20 has a bag opening 21. The waste oil baling device includes a separation device 60 and a baling drive assembly 30. The separation device 60 is positioned corresponding to the bag opening 21 of the recycling bag 20 and is used to separate the bag body on both sides of the bag opening 21. The baling drive assembly 30 is drively connected to the recycling bag 20. The baling drive assembly 30 can drive the recycling bag 20 at the separation device 60 to move to the oil drain outlet, so that the bag opening 21 is in a position corresponding to the oil drain outlet.

[0057] Specifically, the recycling bag 20 is positioned on one side of the separating device 60, and the oil drain is located on the other side. The packaging drive device moves the recycling bag 20 to the other side of the separating device 60. During this movement, the separating device 60 separates the bag body on both sides of the bag opening 21. At this point, the packaging drive device moves the recycled bag 20, now separated, to the oil drain, aligning the bag opening 21 with the drain. After the range hood collects the oil in the oil collection tank, the packaging drive device moves the recycling bag 20 horizontally to the oil drain, allowing the oil in the oil collection tank to drip into the recycling bag 20. After waste oil collection is complete, the user can simply remove the recycling bag 20. This design enables automatic recycling of waste oil extracted by the range hood, simplifying operation and improving the user experience.

[0058] Optionally, the size of the separation device 60 is greater than or equal to the size of the oil leak, so that the size of the opening 21 of the recovery bag 20 at the oil leak is greater than or equal to the size of the oil leak, thereby preventing oil from dripping onto the outside of the recovery bag 20. Here, the size of the opening 21 of the recovery bag 20 refers to the distance between the bag body on both sides of the opening 21.

[0059] like Figures 2 to 6As shown, in some embodiments, the waste oil packaging device further includes a sealing device 40. The sealing device 40 is disposed on one side of the separation device 60 and is used to seal the bag opening 21; wherein, the packaging drive assembly 30 can drive the recycling bag 20 at the oil leakage port to the sealing device 40.

[0060] Specifically, the packaging drive assembly 30 can move the recycling bag 20 to the oil leak point first, and then move it to the sealing device 40. Thus, after the recycling bag 20 has collected the oil, the packaging drive assembly 30 moves it to the sealing device 40. At this point, the sealing device 40 seals the opening 21 of the recycling bag 20 to prevent oil leakage. This design prevents oil from dripping from the recycling bag 20 to other areas after the user removes it, further improving the user experience.

[0061] like Figures 2 to 6 As shown, optionally, the sealing device 40 includes two compression rollers 41, and the compression rollers 41 are equipped with heating elements. Thus, the packaging drive assembly 30 can move the recycling bag 20 at the oil leak point between the two compression rollers 41, and keep the recycling bag 20 moving continuously at a preset speed. At this time, the compression rollers 41 can squeeze the bag body on both sides of the bag opening 21 to make the bag body fit together, and then the heating element heats the bag body to complete the sealing of the bag opening 21.

[0062] Optionally, the range hood also includes a control device and a flow sensor. The flow sensor is electrically connected to the control device, and the packaging drive assembly 30 is also electrically connected to the control device. The flow sensor is located at the oil drain to obtain the oil flow rate at the drain. When the oil flow rate is greater than or equal to a flow threshold, the control device controls the packaging drive assembly 30 to move to the sealing device 40 to seal the bag opening 21. This arrangement prevents excessive oil from leaking out of the recycling bag 20.

[0063] In practical applications, the control device can also determine the amount of oil in the recycling bag 20 based on the oil leakage time or the volume of the recycling bag 20, and if the amount of oil exceeds the preset amount, control the packaging drive component 30 to move the recycling bag 20 to the sealing device 40.

[0064] Optionally, the range hood housing 10 is also provided with an oil collection area 101, and the separation device 60, the packaging drive device and the sealing device 40 are arranged horizontally in the oil collection area 101.

[0065] like Figures 3 to 6As shown, in some embodiments, the packaging drive assembly 30 includes a first drive device 301 and a second drive device 302. The first drive device 301 is disposed between the separating device 60 and the sealing device 40, and is drive-connected to the bag body on the first side of the bag opening 21; the second drive device 302 is disposed between the separating device 60 and the sealing device 40, and is drive-connected to the bag body on the second side of the bag opening 21; wherein, the first drive device 301 and the second drive device 302 can synchronously drive the bag bodies on both sides of the bag opening 21 to move.

[0066] Specifically, the first driving device 301 and the second driving device 302 are arranged parallel to each other, and the distance between the first driving device 301 and the second driving device 302 is greater than or equal to a preset distance. The first driving device 301 and the second driving device 302 are located between the separating device 60 and the sealing device 40, and are respectively located on the front and rear sides of the separating device 60. In this way, when the recycling bag 20 moves to the separating device 60, the bag body on the front and rear sides of the bag opening 21 of the recycling bag 20 is separated by the separating device 60. At this time, the first driving device 301 can drive the bag body on the front side of the bag opening 21 to move to the sealing device 40, and the second driving device 302 can simultaneously drive the bag body on the rear side of the bag opening 21 to move to the oil leakage port, such as... Figure 5 and Figure 6 As shown. Since the distance between the first driving device 301 and the second driving device 302 is greater than or equal to the preset distance, it can be ensured that the size of the bag opening 21 at the oil leak is larger than the size of the oil leak.

[0067] In practical applications, users can manually separate the bag body on one side of the bag opening 21 of the recycling bag 20, and then drive the front and rear sides of the bag body to the first drive device 301 and the second drive device 302 respectively. Alternatively, a separate drive device can be set in the packaging drive assembly 30 to drive the recycling bag 20 to the separation device 60, and drive the front and rear sides of the bag body to the first drive device 301 and the second drive device 302 respectively.

[0068] like Figures 4 to 6 As shown, in some embodiments, the first driving device 301 includes a first packing conveyor belt 311 and a second packing conveyor belt 321, which are arranged parallel to each other along the movement direction of the recycling bag 20; wherein, the first packing conveyor belt 311 can cooperate with the second packing conveyor belt 321 to clamp the bag body on the first side of the bag opening 21.

[0069] Specifically, the first driving device 301 further includes a plurality of first packing drive wheels 312, which are horizontally arranged between the separation device 60 and the sealing device 40 along the direction of movement of the recycling bag 20, and are all located on the front side of the separation device 60. A first packing drive belt 311 is sleeved on the outside of the plurality of first packing drive wheels 312 and is drivenly connected to the plurality of first packing drive wheels 312, so that the first packing drive wheels 312 drive the first packing drive belt 311 to rotate in a preset direction. Similarly, the first driving device 301 also includes a plurality of second packing drive wheels 322, which are evenly arranged parallel to the plurality of first packing drive wheels 312 on the front side of the separation device 60. A second packing drive belt 321 is sleeved on the outside of the plurality of second packing drive wheels 322 and is drivenly connected to the plurality of second packing drive wheels 322, so that the second packing drive wheels 322 drive the second packing drive belt 321 to rotate in a preset direction. There is a first packing gap 33 between the first packing conveyor belt 311 and the second packing conveyor belt 321, and the first packing conveyor belt 311 rotates toward the second packing conveyor belt 321, while the second packing conveyor belt 321 rotates toward the first packing conveyor belt 311.

[0070] After the bag body at the opening 21 is separated by the separating device 60, the bag body in front of the opening 21 can move to the first packing gap 33. At this time, the first packing conveyor belt 311 and the second packing conveyor belt 321 simultaneously squeeze both sides of the bag body in front of the opening 21, and drive the bag body in front of the opening 21 towards the oil leak or the sealing device 40, such as... Figure 5 As shown.

[0071] like Figures 4 to 6 As shown, in some embodiments, the second drive device 302 includes a third packing drive belt 341 and a fourth packing drive belt 351, which are arranged parallel to each other along the movement direction of the recycling bag 20; wherein, the third packing drive belt 341 can cooperate with the fourth packing drive belt 351 to clamp the bag body on the second side of the bag opening 21.

[0072] Specifically, the second drive device 302 further includes a plurality of third packing drive wheels 342, which are horizontally arranged between the separation device 60 and the sealing device 40 along the direction of movement of the recycling bag 20, and all of the third packing drive wheels 342 are located on the rear side of the separation device 60. A third packing transmission belt 341 is sleeved on the outside of the plurality of third packing drive wheels 342 and is drivenly connected to the plurality of third packing drive wheels 342, so that the third packing drive wheels 342 drive the third packing transmission belt 341 to rotate in a preset direction. Similarly, the second drive device 302 also includes a plurality of fourth packing drive wheels 352, which are evenly arranged parallel to the plurality of third packing drive wheels 342 on the rear side of the separation device 60. A fourth packing transmission belt 351 is sleeved on the outside of the plurality of fourth packing drive wheels 352 and is drivenly connected to the plurality of fourth packing drive wheels 352, so that the fourth packing drive wheels 352 drive the fourth packing transmission belt 351 to rotate in a preset direction. There is a second packing gap 36 between the third packing conveyor belt 341 and the fourth packing conveyor belt 351, and the third packing conveyor belt 341 rotates toward the fourth packing conveyor belt 351, while the fourth packing conveyor belt 351 rotates toward the third packing conveyor belt 341.

[0073] After the bag body at the opening 21 is separated by the separating device 60, the bag body behind the opening 21 can move to the second packing gap 36. At this time, the third packing conveyor belt 341 and the fourth packing conveyor belt 351 simultaneously squeeze both sides of the bag body behind the opening 21, and drive the bag body behind the opening 21 towards the oil leak or the sealing device 40, as... Figure 6 As shown.

[0074] like Figure 4 As shown, in some embodiments, the separation device 60 is provided with a first separation surface 61 and a second separation surface 62; the first end of the first separation surface 61 is in the same vertical plane as the bag opening 21, and the second end is inclined between the first packing conveyor belt and the second packing conveyor belt along the movement direction of the recycling bag 20; the first end of the second separation surface 62 is in the same vertical plane as the bag opening 21, and the second end is inclined between the third packing conveyor belt and the fourth packing conveyor belt along the movement direction of the recycling bag 20.

[0075] Specifically, the first separating surface 61 is horizontally arranged along the direction of movement of the recycling bag 20. The first end of the first separating surface 61 is on the same vertical plane as the bag opening 21, and the second end of the first separating surface 61 is inclined towards the first packing gap 33. In this way, the bag body in front of the bag opening 21 of the recycling bag 20 can move along the first separating surface 61 towards the first packing gap 33, so that the first packing conveyor belt 311 and the second packing conveyor belt 321 can clamp the bag body in front of the bag opening 21. Similarly, the second separating surface 62 is horizontally arranged along the direction of movement of the recycling bag 20. The first end of the second separating surface 62 is on the same vertical plane as the bag opening 21, and the second end of the second separating surface 62 is inclined towards the second packing gap 36. In this way, the bag body behind the bag opening 21 of the recycling bag 20 can move along the second separating surface 62 towards the second packing gap 36, so that the third packing conveyor belt 341 and the fourth packing conveyor belt 351 can clamp the bag body behind the bag opening 21.

[0076] like Figure 4 As shown, in some practical applications, the separating device 60 is configured as a triangular prism, with any one corner of the separating device 60 facing the bag opening 21, and the two sides of the corner forming the first separating surface 61 and the second separating surface 62, respectively. In this way, the corner of the separating device 60 can separate the bag body on the front and rear sides of the bag opening 21, and cause the bag body on the front and rear sides of the bag opening 21 to move along the two sides of the triangular prism towards the first packing gap 33 and the second packing gap 36, respectively.

[0077] like Figure 4 As shown, in some embodiments, the waste oil baling device further includes a gathering device 70. The gathering device 70 is disposed between the baling drive assembly 30 and the sealing device 40, and the gathering device 70 is provided with a first gathering surface 71 and a second gathering surface 73; the first gathering surface 71 is inclined along the movement direction of the recycling bag 20 from between the first baling drive belt and the second baling drive belt toward the sealing device 40; the second gathering surface 73 is inclined along the movement direction of the recycling bag 20 from between the third baling drive belt and the fourth baling drive belt toward the sealing device 40.

[0078] Specifically, the gathering device 70 is located between the packing drive device and the sealing device 40. The first gathering surface 71 is horizontally arranged along the direction of movement of the recycling bag 20. The first end of the first gathering surface 71 is on the same vertical plane as the first packing gap 33, and the second end of the first gathering surface 71 is inclined towards the sealing device 40. In this way, the bag body at the front of the bag opening 21 of the recycling bag 20 can move along the first gathering surface 71 towards the sealing device 40, such as... Figure 5As shown. Similarly, the second gathering surface 73 is horizontally arranged along the direction of movement of the recycling bag 20. The first end of the second gathering surface 73 and the second packing gap 36 are on the same vertical plane, and the second end of the second gathering surface 73 is inclined towards the sealing device 40. In this way, the bag body behind the bag opening 21 of the recycling bag 20 can move along the second gathering surface 73 towards the sealing device 40, as shown. Figure 6 As shown.

[0079] like Figure 4 As shown, in some practical applications, the gathering device 70 includes a first gathering block and a second gathering block. The first gathering block is located on the front side of the recycling bag 20, and is inclined toward the side wall of the recycling bag 20 to form a first gathering surface 71. The second gathering block is located on the rear side of the recycling bag 20, and is inclined toward the side wall of the recycling bag 20 to form a second gathering surface 73.

[0080] In the above embodiment, the distance between the second end of the first gathering surface 71 and the second end of the second gathering surface 73 corresponds to the thickness of the recycling bag 20, so that when the recycling bag 20 moves to the second ends of the first gathering surface 71 and the second gathering surface 73, the bag body on both sides of the bag opening 21 fits together. For example, the distance between the second ends of the first gathering surface 71 and the second ends of the second gathering surface 73 can be equal to the thickness of the recycling bag 20, or slightly larger or slightly smaller than the thickness of the recycling bag 20.

[0081] like Figures 1 to 10 As shown, this embodiment of the present disclosure also provides a range hood including: a housing 10, a recycling bag 20, and the aforementioned waste oil packaging device for the range hood. The housing 10 is provided with an oil collection area 101 and an oil collection trough, the oil collection trough being disposed above the oil collection area 101, and the oil collection trough having an oil drain corresponding to the oil collection area 101; the recycling bag 20 having a bag opening 21 corresponding to the oil drain; the waste oil packaging device for the range hood is disposed within the oil collection area 101, including a packaging drive assembly 30, the packaging drive assembly 30 being tractively connected to the recycling bag 20; wherein, the packaging drive assembly 30 can drive the recycling bag 20 to move, so that the bag opening 21 moves to the oil drain.

[0082] Specifically, the range hood also includes an oil fume extraction device, which extracts oil fumes from the environment and collects the oil in an oil collection trough. The oil collection trough is located above the oil collection area 101, and its lower end face has an oil drain outlet, allowing the oil in the trough to flow into the oil collection area 101. The range hood also includes a mounting box 12, which is located on one side of the oil collection area 101. The recycling bag 20 can be stored in and removed from the mounting box 12. The opening 21 of the recycling bag 20 faces upwards to prevent oil leakage.

[0083] When the range hood is running, the waste oil baling device can move the recycling bag 20 from inside the mounting box 12 to the oil drain, and position the bag opening 21 of the recycling bag 20 below the oil drain. In this way, the oil in the oil collection tank can drip into the recycling bag 20 through the oil drain.

[0084] The range hood using the waste oil recovery device provided in this application collects oil in the oil collection tank. After the range hood collects the oil, the packaging drive device moves the recovery bag 20 horizontally to the oil drain, allowing the oil in the oil collection tank to drip into the recovery bag 20. After waste oil recovery is complete, the user can simply remove the recovery bag 20. This design enables automatic recovery of waste oil extracted by the range hood, simplifying operation and improving the user experience.

[0085] like Figure 2 As shown, in some embodiments, the waste oil packaging device further includes a sealing device 40; the housing 10 also includes a storage area 102, which is located on the other side of the sealing device 40 relative to the separation device 60.

[0086] Specifically, the storage area 102 is positioned after the sealing device 40 along the direction of movement of the recycling bag 20. That is, the recycling bag 20 first moves to the sealing device 40 and then to the storage area 102, and the size of the storage area 102 is greater than or equal to the size of the recycling bag 20. The sealing device 40 is used to seal the opening 21 of the recycling bag 20. After the sealing device 40 seals the recycling bag 20, it can continue to move into the storage area 102. This allows the sealed recycling bag 20 to be placed in the storage area 102 first, and the user can remove the recycling bag 20 from the storage area 102 at any time, improving the user experience.

[0087] like Figure 7 As shown, in some embodiments, the range hood further includes a storage drive assembly 50. The storage drive assembly 50 is disposed in the storage area 102 and is connected to the recycling bag 20 for driving the recycling bag 20 to move in a preset direction within the storage area 102.

[0088] Specifically, the storage drive assembly 50 is connected to the sealed recycling bag 20 via a drive mechanism, so that the sealed recycling bag 20 moves in a preset direction within the storage area 102. In this way, the space of the storage area 102 can be effectively utilized.

[0089] Optionally, the storage drive assembly 50 can drive the recycling bag 20 to move horizontally within the storage area 102.

[0090] like Figure 7As shown, in some embodiments, the storage drive assembly 50 includes a first storage drive belt 511 and a second storage drive belt 521, which are arranged parallel to each other along the movement direction of the recycling bag 20; wherein, the first storage drive belt 511 can cooperate with the second storage drive belt 521 to clamp the recycling bag 20 so as to drive the recycling bag 20 to move.

[0091] Specifically, the storage drive assembly 50 further includes a plurality of first storage drive wheels 512, which are horizontally arranged in the storage area 102 along the movement direction of the recycling bag 20. A first storage drive belt 511 is sleeved on the outside of the plurality of first storage drive wheels 512 and is drive-connected to the plurality of first storage drive wheels 512, so that the first storage drive wheels 512 drive the first storage drive belt 511 to rotate in a preset direction. Similarly, the storage drive assembly 50 also includes a plurality of second storage drive wheels 522, which are evenly arranged in the storage area 102 parallel to the plurality of first storage drive wheels 512. A second storage drive belt 521 is sleeved on the outside of the plurality of second storage drive wheels 522 and is drive-connected to the plurality of second storage drive wheels 522, so that the second storage drive wheels 522 drive the second storage drive belt 521 to rotate in a preset direction. The size of the storage gap between the first storage drive belt 511 and the second storage drive belt 521 is the same as the size of the gap between the two extrusion rollers 41.

[0092] After the sealing device 40 seals the bag body on both sides of the bag opening 21 into a single sealed edge, the recycling bag 20 can continue to move so that the sealed edge moves into the storage gap. At this time, the first storage drive belt 511 and the second storage drive belt 521 can clamp the recycling bag 20 from both sides of the sealed edge to drive the recycling bag 20 to move within the storage area 102.

[0093] In some embodiments, the range hood further includes a volume sensor and an alarm device. The volume sensor is used to obtain the volume of the recycling bag 20 in the storage area 102; the alarm device is electrically connected to the volume sensor; wherein, if the volume of the recycling bag 20 in the storage area 102 is greater than or equal to a preset volume, the volume sensor can trigger the alarm device.

[0094] Specifically, a volume sensor is positioned at the location corresponding to the storage area 102 on the housing 10, and the volume sensor is used to obtain the volume of the recycling bag 20 within the storage area 102. If the volume of the recycling bag 20 is greater than or equal to a preset volume, the volume sensor can trigger an alarm device to remind the user to remove the recycling bag 20.

[0095] In practical applications, the preset volume can be set according to the user's actual needs. For example, if the volume of the recycling bag 20 is greater than or equal to half the volume of the storage area 102, the volume sensor can trigger an alarm device.

[0096] In the above embodiments, the warning device is configured to emit sound signals, light signals, or text signals.

[0097] like Figures 1 to 8 As shown, in some embodiments, the housing 10 has an opening at a position corresponding to the oil collection area 101 and / or storage area 102; the range hood also includes a cover plate 11. The cover plate 11 is rotatably disposed on the housing 10, and the cover plate 11 can cover the opening.

[0098] Specifically, the side wall of the housing 10 corresponding to the oil collection area 101 has an opening, through which the user can install the recycling bag 20. Similarly, the side wall of the housing 10 corresponding to the storage area 102 has an opening, through which the user can remove the recycling bag 20 from the storage area 102. The cover plate 11 is mounted on the housing 10 via a pivot, and the cover plate 11 can rotate around the pivot to open or close the opening.

[0099] Optionally, a guide rod 111 is provided on the side of the cover plate 11 facing the housing 10. The guide rod 111 is configured in an arc shape and is concentric with the rotating shaft. An arc-shaped guide groove 13 is provided on the housing 10 at the position corresponding to the guide rod 111, and the guide rod 111 can be inserted into the guide groove 13. In this way, during the rotation of the cover plate 11, the guide rod 111 can move along the guide groove 13 to guide the cover plate 11.

[0100] Optionally, the end of the guide rod 111 inserted into the guide groove 13 is provided with a protruding edge, and the end of the guide groove 13 near the cover plate 11 is provided with a limiting protrusion. In this way, after the cover plate 11 rotates away from the housing 10 to a preset distance, the limiting protrusion can abut against the protruding edge of the guide rod 111 to prevent the cover plate 11 from continuing to rotate and causing the guide rod to fall out of the guide groove.

[0101] like Figure 9 and Figure 10 As shown, in some embodiments, the edges of the bag opening 21 of the recycling bag 20 are provided with clearance openings 22; wherein, the separation device 60 can move relative to the recycling bag 20 to move through the clearance openings 22 to the bag opening 21.

[0102] Specifically, the left and right edges of the recycling bag 20 are provided with clearance openings 22, which are corresponding to the bag opening 21 so that the bag opening 21 passes through the entire recycling bag 20. The size of the clearance opening 22 is greater than or equal to the size of the separating device 60. Thus, when the recycling bag 20 and the separating device 60 move relative to each other, the separating device 60 can move through the clearance opening 22 to the bag opening 21, thereby separating the bag body on the front and rear sides of the bag opening 21.

[0103] like Figure 9 and Figure 10 As shown, in some embodiments, the recycling bag 20 includes a plurality of independent sub-recycling bags 20, and the plurality of sub-recycling bags 20 are connected and extended in a horizontal direction.

[0104] Specifically, a storage shaft is vertically arranged inside the mounting box 12, and multiple sub-collection bags 20 are wound around the outside of the storage shaft to store the multiple sub-collection bags 20 inside the mounting box 12. The outermost sub-collection bag 20 is connected to the packing drive assembly 30, and the packing drive assembly 30 can drive the other sub-collection bags 20 to move synchronously through the outermost sub-collection bag 20. After any sub-collection bag 20 completes oil collection, the packing drive assembly 30 drives the sub-collection bag 20 to the sealing device 40 to seal the sub-collection bag 20, and drives the next sub-collection bag 20 to the oil leak to continue collecting oil. This arrangement can achieve continuous oil collection for a long time and can also avoid the individual collection bags 20 being too large.

[0105] like Figure 9 and Figure 10 As shown, in some embodiments, a tear line 23 is provided at the junction of two adjacent sub-recycling bags 20.

[0106] Specifically, a vertical tear line 23 is provided at the connection point of two adjacent sub-recycling bags 20, allowing users to separate adjacent sub-recycling bags 20 from the tear line. This design makes it easier for users to retrieve some sub-recycling bags 20 from the storage area 102.

[0107] Optionally, an oil drain pipe is also provided at the oil drain port of the housing 10, extending towards the inside of the recovery bag 20. In this way, oil in the oil collection tank can drip into the recovery bag 20 sequentially through the oil drain port and the oil drain pipe. The size of the oil drain pipe is smaller than the size of the clearance opening 22. This design prevents oil from dripping onto the outside of the recovery bag 20.
