Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an oil cup and a range hood. Background Technology

[0002] Traditional oil cups are widely used in daily life, and their main function is to collect waste oil generated during equipment operation.

[0003] In existing technologies, oil cup designs are mostly focused on simplicity and practicality, with low levels of intelligence. Users typically rely on experience or periodic checks to judge the amount of waste oil inside traditional oil cups, rarely actively monitoring it. This lack of intelligent monitoring prevents users from promptly understanding the cup's status and from taking appropriate measures when waste oil is about to overflow, potentially leading to spills that increase cleaning difficulty and could disrupt normal equipment operation. Furthermore, during disassembly, traditional designs often cause some waste oil to drip out, polluting the environment and potentially posing a health threat to users. This environmentally unfriendly design contradicts the growing environmental awareness and sustainable development concepts of modern society, limiting the wider application and development of oil cups. Utility Model Content

[0006] The first drive mechanism is connected between the cup body and the cup lid. The first drive mechanism is used to drive the cup lid to close the opening of the cup body when the gravity sensing structure detects that the oil in the oil cup has reached a preset weight value.

[0007] Furthermore, the gravity sensing structure includes a connecting rod, a connecting spring, and an infrared sensor. The lower end of the connecting rod is connected to the cup body, the upper end of the connecting rod is connected to one end of the connecting spring, and the other end of the connecting spring is connected to the suspension part.

[0008] An infrared sensor is mounted on the suspension part, and the detection light path of the infrared sensor is arranged vertically. It is used to send a drive signal to the first drive mechanism when the distance between the cup body and the suspension part is greater than a preset length.

[0009] Furthermore, the gravity sensing structure also includes an outer sleeve, the lower end of which is connected to a connecting rod;

[0010] Both the connecting spring and the infrared sensor are located inside the outer tube.

[0011] Furthermore, the cup lid includes at least two lid pieces, each of which is connected to the first drive mechanism via a linkage component, so that the first drive mechanism drives the lid pieces to converge and close the opening or to expand and open the opening via the linkage component.

[0012] Furthermore, each lid is equipped with a toothed rack, all of which are arranged radially and are slidably connected to the cup body along their length.

[0013] The first drive mechanism includes an internal gear frame, gears, and a first motor. The internal gear frame is rotatably connected to the cup body; the gears mesh with the internal gear frame; the number of gears is the same as the number of racks, and they correspond one-to-one.

[0014] The drive shaft of the first motor is coaxially connected to one of the gears.

[0015] Furthermore, the suspension unit is internally equipped with a clamping component and a second drive mechanism, which is used to drive the clamping component to move toward or away from the suspension unit.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0043] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] like Figure 1 and Figure 2 As shown, the oil cup 3 provided by this utility model is installed on the smoke collection hood, and two oppositely arranged collection nets 2 are installed at the bottom of the smoke collection hood, with the bottom of the collection nets 2 connected to the oil cup 3.

[0045] like Figure 3 and Figure 4 As shown, the oil cup 3 includes: a suspension part 39, a gravity sensing structure, a cup body 302, a cup lid, and a first drive mechanism.

[0046] The suspension part 39 is used to connect with the smoke hood. The oil cup 3 is connected to the smoke hood through the suspension part 39. The circumferential outer wall of the suspension part 39 may be provided with threads for threaded connection with the smoke hood.

[0047] like Figure 4 As shown, a battery mounting frame 301 is installed at the bottom of the cup body 302 to form a battery compartment, where the battery powers the first and second drive mechanisms inside the cup body 302. The cup body 302 is transparent to allow observation of the internal oil level.

[0048] like Figure 5As shown, the upper end of the gravity sensing structure is connected to the suspension part 39, and the lower end of the gravity sensing structure is connected to the cup body 302. Specifically, the gravity sensing structure includes a connecting spring 37 and an infrared sensor 38. Dampers are provided at both ends of the connecting spring 37. The lower end of the connecting spring 37 is connected to the top end of the connecting rod 36, and the lower end of the connecting rod 36 is connected to the bottom of the cup body 302. The upper end of the connecting spring 37 is connected to the bottom end of the suspension part 39. The infrared sensor 38 is located at the bottom end of the suspension part 39. The infrared sensor 38 emits sensing light downwards. As the amount of oil in the oil cup 3 increases, the connecting spring 37 is stretched, and the distance detected by the infrared sensor 38 increases. The increased distance is proportional to the weight of the oil. When the distance between the cup body 302 and the suspension part 39 exceeds a preset length, a drive signal is sent to the first drive mechanism. The oil cup 3 can then issue an alarm and use the first drive mechanism to drive the cup lid to close the opening of the cup body 302.

[0049] like Figure 4 As shown, the gravity sensing structure also includes an outer sleeve 41, the lower end of which is connected to the connecting rod 36. The connecting spring 37 and the infrared sensor 38 are both located inside the outer sleeve 41 to prevent them from being contaminated by oil. The connecting rod 36 and the outer sleeve 41 can be integrally formed.

[0050] like Figure 6 and Figure 7 As shown, the first drive mechanism includes a first motor 32, which is fixedly connected inside the cup body 302. Six circumferentially distributed gears 321 are rotatably mounted inside the opening of the oil cup 3, with one gear 321 mounted at the output end of the first motor 32. An internal gear frame 33 is rotatably mounted inside the cup body 302, and a bearing connects the internal gear frame 33 to the cup body 302. All six gears 321 mesh with the internal gear frame 33. Six circumferentially distributed racks 34 are slidably assembled inside the cup body 302, with each gear 321 meshing with one rack 34. A cover plate 35 is fixedly connected to the top of each rack 34. The cover plates 35 are fan-shaped, and the central area of ​​the six cover plates 35 is a connecting rod 36. The first motor 32 drives the internal gear frame 33 to rotate clockwise or counterclockwise, causing the six gears to move towards or away from the center.

[0051] To prevent the connection between the suspension part 39 and the smoke hood from becoming loose, the suspension part 39 is provided with a clamping member and a second drive mechanism. The second drive mechanism is used to drive the clamping member to move toward or away from the suspension part.

[0052] Once the suspension part 39 is tightened into place, the clamping part moves away from the suspension part, thereby abutting against the inner wall of the screw hole of the smoke hood, increasing friction and preventing loosening.

[0053] Specifically, such as Figure 5 and Figure 8As shown, the clamping component includes a clamping block 45 and a driven bevel gear 43, with the clamping block 45 connected to the driven bevel gear 43. Limiting holes are provided on the side wall of the suspension portion 39, with the number of limiting holes matching the number of clamping blocks 45, and they correspond one-to-one. The clamping component is slidably connected within the limiting holes along the inner and outer directions of the suspension portion 39, and the limiting holes prevent the clamping block from rotating around the axis of the driven bevel gear 43. The second drive mechanism includes a second motor 40 and a driving bevel gear 42, with the driving bevel gear 42 coaxially connected to the output shaft of the second motor 40. Each driven bevel gear 43 is distributed circumferentially along the driving bevel gear 42 and meshes with it.

[0054] like Figure 8 As shown, a second motor 40 is installed inside the suspension part 39. A rotating shaft is installed at the output end of the second motor 40, and a driving bevel gear 42 is fixedly connected to the top of the rotating shaft. Four circumferentially distributed screws 44 are rotatably installed inside the suspension part 39. One end of each screw 44 is fixedly connected to a driven bevel gear 43, and all four driven bevel gears 43 mesh with the driving bevel gear 42. A locking block 45 is threaded onto the outer circumferential surface of the screw 44. After the driving bevel gear 42 rotates, it drives the four driven bevel gears 43 to rotate. Because the locking block 45 is limited by the limiting hole, it is prevented from rotating. Therefore, the locking block 45 can only move along the limiting hole.

[0055] like Figure 3 As shown, the opening edge of the cup body 302 is provided with an outwardly extending skirt 31. From top to bottom, the cross-section of the skirt 31 gradually decreases. When oil falls on the skirt 31, the oil will slide into the oil cup 3 along the skirt 31. The skirt 31 is provided to increase the area of ​​the oil cup 3 for collecting oil.

[0056] When using the oil cup 3, first rotate and screw the suspension part 39 to the bottom of the collection net 2. Then, turn on the second motor 40 via remote control. The rotation of the second motor 40 causes the active bevel gear 42 to rotate. When the active bevel gear 42 rotates, it meshes with the driven bevel gear 43, causing the driven bevel gear 43 to rotate. The rotation of the driven bevel gear 43 causes the screw 44 to rotate. The rotation of the screw 44 causes the locking block 45 to extend outward for locking, preventing the oil cup 3 from loosening due to vibration caused by the use of the range hood 1 during the connection between the suspension part 39 and the collection net 2, making the use of the oil cup 3 more stable.

[0057] During the use of oil cup 3, waste oil flows into cup body 302. Due to gravity and the connecting spring 37 (which has corresponding dampers at both ends), the connecting spring 37 is stretched, the connecting rod 36 descends, and the infrared sensor 38 detects its displacement. When the displacement reaches the preset value detected by the infrared sensor 38, a signal is sent to the external controller. When the external controller receives the signal, it can turn on the LED bead 391 located on the suspension part 39 to make it flash or emit a voice alarm sound. At the same time, the rotation of the first motor 32 causes one of the gears 321 to rotate. When this gear 321 rotates, it drives the inner gear frame 33 to rotate. The rotation of the inner gear frame 33 drives the other gears 321 to rotate. The rotation of the gears 321 causes the rack 34 to slide. The sliding of the rack 34 causes the cover plates 35 to fit together and seal the top opening of the cup body 302. At this time, the second motor 40 also reverses and retracts the locking block 45, so that the suspension part 39 can be removed. By sealing the top of the oil cup 3, waste oil can be effectively prevented from dripping when the oil cup 3 is removed, making the use of the oil cup 3 more intelligent and environmentally friendly.

[0058] The range hood 1 provided by this utility model includes the aforementioned oil cup 3. Because the range hood 1 provided by this utility model uses the aforementioned oil cup 3, it also possesses the advantages of the oil cup 3.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
