[0049] Next, refer to Figures 1 to 6 Describe an oil stain collection device and a range hood according to some embodiments of the present application.

[0050] The present application provides an oil stain collection device, as Figure 1 shown, for a side-suction range hood to automatically collect and package the oil fume in the range hood.

[0051] As Figure 2 and Figure 3 shown, the oil stain collection device includes an oil collector 1 and a sealing device 3.

[0052] An oil drip tray 2 is provided below the range hood to receive the waste oil of the whole range hood through the oil drip tray 2, such as the waste oil on the fan, smoke collecting hood, and front side panel of the range hood. And an oil discharge port 21 is opened on the bottom wall of the oil drip tray 2, and the waste oil in the oil drip tray 2 can flow to the oil drip tray 2 through the oil discharge port 21 on the bottom wall.

[0053] The oil collector 1 is a container with an open upper end and a predetermined volume to be able to store a certain amount of waste oil. The oil collector 1 can be detachably placed below the oil drip tray 2, and the opening at the upper end of the oil collector 1 is directly opposite to the oil discharge port 21 at the bottom of the oil drip tray 2, so that the waste oil in the oil drip tray 2 can flow into the oil collector 1 through the oil discharge port 21 to temporarily store the waste oil through the oil collector 1. And when a certain amount of waste oil is stored in the oil collector 1, the user can take out the oil collector 1 filled with waste oil from below the oil drip tray 2, and then replace it with a new oil collector 1 and place it below the oil drip tray 2 to continue receiving the waste oil flowing out of the oil drip tray 2.

[0054] The sealing device 3 is installed on the housing of the range hood below the oil collector 2. The sealing device 3 can press and seal the open end of the oil collector 1 to achieve the sealed packaging of the oil collector 1. When a certain amount of waste oil is stored in the oil collector 1 and the oil collector 1 below the oil collector 2 needs to be replaced, the user can first automatically package the oil collector 1 filled with waste oil below the oil collector 2 through the sealing device 3, and then the user can directly take out the packaged oil collector 1 and conduct garbage classification, so as to quickly and conveniently complete the cleaning of the waste oil, avoid the direct contact between the user and the waste oil and cause dirt, and thus improve the user experience to a certain extent.

[0055] In an embodiment of the present application, preferably, the oil collector 1 is an oil collecting bag made of plastic, and the open end of the oil collecting bag can be expanded so that the waste oil in the oil collector 2 can flow into the oil collecting bag.

[0056] Preferably, as Figures 3 to 5 shown, a first support member 12 and a second support member 13 are arranged at intervals along the first direction a, that is, the length direction of the range hood, below the oil collector 2, and the first support member 12 and the second support member 13 are respectively located on both sides of the first direction a of the oil discharge port 21 of the oil collector 2.

[0057] Hanging rings 11 are respectively arranged on both sides of the open end of the oil collecting bag in the first direction a. The hanging rings 11 at both ends of the oil collecting bag can be respectively hung on the first support member 12 and the second support member 13, so that the oil collecting bag is hung below the oil collector 2, and the open end of the oil collecting bag is expanded by the first support member 12 and the second support member 13, so that the open end of the oil collecting bag is directly opposite to the oil discharge port 21 of the oil collector 2, and thus the oil collecting bag can receive the waste oil flowing out of the oil collector 2.

[0058] When the oil collecting bag needs to be replaced, the user only needs to remove the hanging rings 11 on both sides of the oil collecting bag from the first support member 12 and the second support member 13 to quickly and conveniently disassemble and replace the oil collecting bag.

[0059] Preferably, as Figure 3 shown, the first support member 12 and the second support member 13 can be support rods, the length direction of the support rods is arranged along the front-back direction of the range hood, and the two support rods are arranged side by side at intervals on both sides of the oil discharge port 21 along the first direction a. The hanging rings 11 on both sides of the oil collecting bag can be sleeved on the two support rods, so as to support and suspend the oil collecting bag through the two support rods, and also expand the open end of the oil collecting bag through the two support rods, so that the open end of the oil collecting bag located below the oil collector 2 is always in an open state to receive the waste oil flowing out of the oil collector 2.

[0060] Preferably, the first support member 12 and the second support member 13 can also be hooks, and the hanging rings 11 on both sides of the oil collecting bag can be hung on the hooks, so that the oil collecting bag can be hung below the oil discharge port 21 of the oil collecting tray 2 in a state where the opening is open.

[0061] In an embodiment of the present application, preferably, since the oil collector 1 is an oil collecting bag made of plastic, the sealing device 3 can seal and pack the oil collecting bag by thermoplastic sealing.

[0062] Preferably, as Figure 5 shown, the sealing device 3 includes a driving mechanism, a first thermoplastic sealing member 31 and a second thermoplastic sealing member 32.

[0063] The first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 are relatively spaced apart on both sides of the first direction a of the oil collecting bag, and both the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 can move along the first direction a to approach or move away from the oil collecting bag.

[0064] The driving mechanism can drive the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 to move, so that the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 can simultaneously move towards the oil collecting bag to clamp the open end of the oil collecting bag, or make the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 move away from the oil collecting bag at the same time, so that the oil collecting bag is suspended below the oil collecting tray 2 in an open state.

[0065] When the oil collecting bag needs to be packed, the driving mechanism drives the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 to move towards the oil collecting bag at the same time, so that the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 clamp the open end of the oil collecting bag, and then the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 perform thermoplastic sealing on the open end of the oil collecting bag to achieve the sealing and packing of the oil collecting bag. Thus, when the user needs to clean the oil in the oil collecting bag, the user can directly take out the oil collecting bag for garbage recycling without direct contact with the waste oil.

[0066] In this embodiment, preferably, both the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 include clamping blocks and heating elements. The heating elements are arranged on the clamping blocks, and the clamping blocks can be heated through the heating elements, so that when the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 clamp the oil collecting bag, thermoplastic sealing can be performed on the oil collecting bag.

[0067] Preferably, the clamping blocks of the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 are serrated at the ends facing the oil collecting bag. Thus, when clamping and sealing the oil collecting bag through the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32, the sealing of the oil collecting bag can be made denser. Furthermore, after the oil collecting bag is sealed, the waste oil in the oil collecting bag will not leak, causing the user's clothes or skin to get dirty, nor will it cause environmental pollution due to the leakage of waste oil.

[0068] In this embodiment, preferably, as Figure 5 shown, the sealing device 3 includes a guide rod 39. Both ends of the guide rod 39 in the length direction are installed on the casing of the range hood through fixed seats, and the length direction of the guide rod 39 is along the first direction a. The first thermoplastic sealing member 31 is provided with a first base 33, and the first base 33 is slidably sleeved on the guide rod 39, so that the first thermoplastic sealing member 31 can reciprocally slide along the length direction of the guide rod 39, that is, the first direction a.

[0069] The second thermoplastic sealing member 32 is provided with a second base 34, and the second base 34 is also slidably sleeved on the guide rod 39, so that the second thermoplastic sealing member 32 can reciprocally slide along the length direction of the guide rod 39, that is, the first direction a.

[0070] Preferably, as Figure 5 shown, the driving mechanism is used to drive the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 to move. The driving mechanism includes a first rack 35, a second rack 36, a transmission gear 37 and a driving device 38.

[0071] The length direction of the first rack 35 is along the first direction a, and one end of the first rack 35 in the length direction is connected to the first base 33, and the other end of the first rack 35 in the length direction extends towards the second base 34; the length direction of the second rack 36 is along the first direction a, and one end of the second rack 36 in the length direction is connected to the second base 34, and the other end of the second rack 36 in the length direction extends towards the first base 33.

[0072] The first rack 35 and the second rack 36 are spaced apart by a predetermined distance in a direction perpendicular to the first direction a. The transmission gear 37 is arranged between the first rack 35 and the second rack 36. The transmission gear 37 can rotate around its own axis, and the transmission gear 37 meshes with the first rack 35 and the second rack 36 on both sides respectively.

[0073] The driving device 38 is installed on the casing of the range hood, and the driving end of the driving device 38 is connected to the first base 33. The driving device 38 can drive the first base 33 and the first rack 35 arranged on the first base 33 to move, and through the transmission of the transmission gear 37, the second rack 36 and the second base 34 can also move accordingly.

[0074] Preferably, the driving device 38 is an electric push rod, which can expand and contract along the first direction a, so as to drive the first base 33 to reciprocate along the first direction a.

[0075] Specifically, when it is necessary to make the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 move towards the oil collecting bag to clamp the oil collecting bag and perform thermoplastic sealing on the oil collecting bag, the driving device 38 is used to drive the first base 33 to move along the first direction a towards the second base 34, so as to drive the first thermoplastic sealing member 31 to move towards the oil collecting bag, and at the same time the first rack 35 moves accordingly. With the movement of the first rack 35, through the meshing transmission of the transmission gear 37, the second rack 36 will move in the direction opposite to that of the first rack 35, so as to drive the second base 34 to move along the first direction a towards the first base 33, and further make the second thermoplastic sealing member 32 move along the first direction a towards the oil collecting bag, realizing the clamping and sealing of the oil collecting bag by the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32.

[0076] Similarly, when it is necessary for the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 to move away from the oil collecting bag, only by driving the first base 33 to move away from the second base 34 through the driving device 38, through the meshing transmission between the first rack 35, the second rack 36 and the transmission gear 37, it is also possible to make the second base 34 move away from the first base 33, so that the first thermoplastic sealing member 31 and the second thermoplastic sealing member 32 move away from the oil collecting bag at the same time.

[0077] In this embodiment, as Figure 6 shown, a first guiding hole 310 is provided at the position of the first base 33 opposite to the second rack 36, so that one end of the second rack 36 away from the second base 34 can be inserted into the first base 33 through the first guiding hole 310; thus, the second rack 36 is supported by the first base 33, so that the length direction of the second rack 36 can always be kept along the horizontal first direction a, and the movement of the second rack 36 is guided through the first guiding hole 310, so that the movement direction of the second rack 36 can be kept in the second direction.

[0078] Similarly, a second guiding hole 311 is provided at the position of the second base 34 opposite to the first rack 35, and one end of the first rack 35 away from the first base 33 can be inserted into the second base 34 through the second guiding hole 311; thus, the first rack 35 is supported by the second base 34, so that the length direction of the first rack 35 is always kept along the horizontal first direction a, and the movement of the first rack 35 is guided through the second guiding hole 311, so that the movement direction of the first rack 35 can be kept along the first direction a.

Both the oil collector 1 and the sealing device 3 are disposed in the receiving chamber. During normal use of the range hood, that is, when the oil collector 1 does not need to be replaced, the decorative plate 4 is in a closed state to close the receiving chamber, thereby hiding the oil collector 1 and the sealing device 3, improving the integrity and aesthetics of the range hood; and when the oil collector 1 in the receiving chamber needs to be replaced, it is only necessary to open the decorative plate 4.

[0080] In this embodiment, preferably, the lower end of the decorative plate 4 is pivotally connected to the housing of the range hood, so that the decorative plate 4 can be turned downward to an open state to facilitate the user to replace the oil collector 1.

[0081] Preferably, as Figure 3 shown, first fixing buttons 41 are provided at the edges on both sides of the decorative plate 4 along the first direction a, and second fixing buttons 42 are provided on the side walls on both sides of the receiving chamber of the housing of the range hood along the first direction a. The first fixing buttons 41 and the second fixing buttons 42 are adapted to each other, so that the decorative plate 4 can be snap-connected to the side walls on both sides of the receiving chamber, thereby realizing the closure of the receiving chamber by the decorative plate 4.

[0082] Preferably, the first fixing buttons 41 and the second fixing buttons 42 can be magnetic members to realize the snap connection of the decorative plate 4 by means of magnetic attraction.

[0083] The present application also provides a range hood, as Figure 1 shown, including the oil stain receiving device of any of the above embodiments.

[0084] In this embodiment, the range hood includes the oil stain receiving device, so the range hood has all the beneficial effects of the oil stain receiving device, which will not be elaborated here one by one.

[0085] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
