Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an oil collection device and an oil fume extraction device. Background Technology

[0002] Range hoods, integrated cooktops, and other appliances with fume extraction functions mainly use negative pressure adsorption to draw fumes into their interiors. During the fume extraction process, oil droplets are generated inside the machine. Oil cups or oil boxes are usually installed to collect the oil, thereby preventing oil from dripping onto the cooking area of ​​the stove and ensuring a clean and safe kitchen environment.

[0003] Currently, common oil cups typically only have the function of collecting oil. Users usually do not know how much oil is in the oil cup and need to clean the oil cup regularly based on their personal experience. If it is not cleaned in time, the oil will continue to accumulate in the oil cup, which can easily lead to oil overflow and affect the user experience.

[0004] To facilitate observation of the oil level in the oil cup, some oil cups are equipped with a transparent window structure, allowing users to directly observe the oil level through the window. However, in actual use, the surface of the transparent window is easily covered by oil stains, reducing the clarity of observation and affecting the accuracy of judgment. Furthermore, visual observation is inconvenient in low light conditions or when the installation location is not convenient for direct viewing. Other oil cups determine the oil level by weighing the cup to detect changes in weight. However, this solution relies on the deformation of an elastic element to achieve weight sensing. Under long-term load, the elastic element is prone to fatigue aging and decreased sensitivity, leading to reduced detection accuracy and affecting the reliability of oil level monitoring.

[0005] Therefore, there is an urgent need for an oil collection device and an oil fume extraction device to solve the above problems. Utility Model Content

[0006] Based on the above problems, the purpose of this utility model is to provide an oil collection device and an oil fume extraction device that enables users to know the oil level of the oil collection device, making it convenient for users to clean it in a timely manner, while ensuring the accuracy and reliability of oil level detection and improving the user experience.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a first aspect, an oil collection device is provided, comprising:

[0009] An oil collection box is used to collect oil. The oil collection box includes a first side plate and a second side plate that are arranged opposite to each other.

[0010] The detection component includes a signal transmitting module and a signal receiving module. The signal transmitting module is disposed on the first side plate, and the signal receiving module is disposed on the second side plate and is directly opposite to the signal transmitting module.

[0011] The signal transmitting module includes a transmitting end, and the signal receiving module includes multiple receiving ends. Each receiving end is capable of receiving the signal emitted by the transmitting end. The multiple receiving ends are arranged at intervals along the depth direction of the oil collection box, and each receiving end corresponds to a liquid level height.

[0012] As an optional solution for the oil collection device of this utility model, a first receiving cavity is provided on the first side plate. The first receiving cavity is independent of the inner cavity of the oil collection box, and the signal transmitting module is located in the first receiving cavity.

[0013] A second receiving cavity is provided on the second side plate. The second receiving cavity is independent of the inner cavity of the oil collection box, and the signal receiving module is located in the second receiving cavity.

[0014] As an optional embodiment of the oil collection device of this utility model, the first side plate is provided with a first enclosure structure inside the oil collection box, and the first enclosure structure encloses and forms a first receiving cavity; the second side plate is provided with a second enclosure structure inside the oil collection box, and the second enclosure structure encloses and forms a second receiving cavity.

[0015] As an optional solution for the oil collection device of this utility model, the oil collection device also includes an alarm module, and both the alarm module and the detection component are communicatively connected to the control system.

[0016] The signal receiving module includes a first receiving end, and the liquid level at the first receiving end is the first warning liquid level. When the first receiving end detects that the liquid level in the oil collection box has reached the first warning liquid level, the alarm module issues a first prompt message.

[0017] As an optional solution for the oil collection device of this utility model, the signal receiving module includes a second receiving end, and the liquid level height at which the second receiving end is located is the second warning liquid level. When the liquid level in the oil collection box is detected to reach the second warning liquid level through the second receiving end, the alarm module issues a second prompt message.

[0018] The second warning level is higher than the first warning level.

[0019] As an optional solution for the oil collection device of this utility model, the signal receiving module includes a third receiving end, and the position of the third receiving end is higher than the highest liquid level in the oil collection box.

[0020] As an optional solution for the oil collection device of this utility model, the oil collection box is provided with a connecting structure, which is used to detachably connect with the installation foundation. The connecting structure is provided with an oil guiding structure, which is used to guide the oil between the installation foundation and the connecting structure into the oil collection box.

[0021] As an optional solution for the oil collection device of this utility model, the connecting structure includes a connecting plate;

[0022] The oil guiding structure includes an oil guiding inclined surface disposed on the connecting plate, the oil guiding inclined surface being inclined toward the interior of the oil collection box; and / or, the oil guiding structure includes an oil guiding groove disposed on the connecting plate, the oil guiding groove communicating with the inner cavity of the oil collection box.

[0023] As an optional solution for the oil collection device of this utility model, the signal transmitting module includes an ultrasonic transmitting device, and the signal receiving module includes an ultrasonic receiving device.

[0024] Secondly, a fume extraction device is provided, including a housing and the aforementioned oil collection device, wherein the oil collection device is installed in the housing.

[0025] The beneficial effects of this utility model are as follows:

[0026] The oil collection device and fume extraction equipment provided by this utility model allow the transmitting end of the signal transmitting module to transmit signals to multiple receiving ends of the signal receiving module. Since the multiple receiving ends are spaced apart along the depth direction of the oil collection chamber, the time it takes for each receiving end to receive the signal transmitted by the transmitting end is different. Furthermore, for the same receiving end, the time it takes for the receiving end to receive the signal differs depending on whether the liquid level in the oil collection box has not reached the height of the receiving end or has already reached the height of the receiving end. Therefore, by obtaining the time it takes for each receiving end to receive the signal, the specific liquid level in the oil collection box can be determined.

[0027] Specifically, for each receiving end, the time taken for that receiving end to receive the signal when the liquid level in the oil collection box reaches the height of the corresponding receiving end is a preset duration. This preset duration can be pre-stored in the control system of the fume extraction equipment. Then, the actual duration taken for the receiving end to receive the signal is obtained and compared with the corresponding preset duration. If the actual duration reaches the preset duration, it indicates that there is already oil at the location of the corresponding receiving end. When, among two adjacent receiving ends, the actual duration taken for the lower receiving end to receive the signal reaches the corresponding preset duration, while the actual duration taken for the upper receiving end to receive the signal does not reach the corresponding preset duration, it indicates that the current liquid level in the oil collection box has reached the position of the lower receiving end. Thus, the liquid level in the oil collection box is determined based on the liquid level height of the receiving end.

[0028] In other words, this oil collection device can obtain the liquid level in the oil collection box in real time, allowing users to know the amount of oil in the box promptly. This avoids situations where there is too much oil without the user's knowledge, preventing oil spills and improving the user experience. Furthermore, this oil collection device eliminates the need for visual inspection, making it more convenient to use. Moreover, it detects the liquid level through signal transmission and reception, unaffected by the aging of the mechanical structure, ensuring the accuracy of the detection results.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] 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.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Specifically, the terms "first position" and "second position" refer to two different positions.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between 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.

[0049] This embodiment provides an oil collection device that enables users to know the oil level of the oil collection device, facilitating timely cleaning by users, while ensuring the accuracy and reliability of oil level detection, thereby improving the user experience.

[0050] like Figure 1 and Figure 2As shown, the oil collection device includes an oil collection box 1 and a detection component 2. The oil collection box 1 is used to collect oil and includes a first side plate 11 and a second side plate 12 arranged opposite to each other. The detection component 2 includes a signal transmitting module 21 and a signal receiving module 22. The signal transmitting module 21 is disposed on the first side plate 11, and the signal receiving module 22 is disposed on the second side plate 12, directly opposite to the signal transmitting module 21. The signal transmitting module 21 includes a transmitting end 211, and the signal receiving module 22 includes multiple receiving ends, each capable of receiving the signal emitted by the transmitting end 211. The multiple receiving ends are arranged at intervals along the depth direction of the oil collection box 1, and each receiving end corresponds to a liquid level height. That is, when the signal receiving module 22 is installed in the oil collection box 1, the positions of the multiple receiving ends are fixed. Therefore, the liquid level height corresponding to each receiving end in the oil collection box 1 is determined. The liquid level in the oil collection box 1 can be determined by obtaining the time taken for each receiving end to receive the signal.

[0051] In the oil collection device provided in this embodiment, the transmitting end 211 of the signal transmitting module 21 can transmit signals to multiple receiving ends of the signal receiving module 22. Since the multiple receiving ends are spaced apart along the depth direction of the oil collection cavity, the time taken for each receiving end to receive the signal transmitted by the transmitting end 211 is different. Furthermore, for the same receiving end, the time taken for the receiving end to receive the signal is different when the liquid level in the oil collection box 1 has not reached the height of the receiving end and when the liquid level has reached the height of the receiving end. Therefore, by obtaining the time taken for each receiving end to receive the signal, the specific liquid level in the oil collection box 1 can be determined.

[0052] Specifically, for each receiving end, when the liquid level in the oil collection box 1 reaches the height of the corresponding receiving end, the time taken for that receiving end to receive the signal is a preset duration. This preset duration can be pre-stored in the control system of the fume extraction equipment. Then, the actual duration taken for the receiving end to receive the signal is obtained and compared with the corresponding preset duration. If the actual duration reaches the preset duration, it indicates that there is already oil at the location of the corresponding receiving end. When, among two adjacent receiving ends, the actual duration taken for the lower receiving end to receive the signal reaches the corresponding preset duration, while the actual duration taken for the upper receiving end to receive the signal does not reach the corresponding preset duration, it indicates that the current liquid level in the oil collection box 1 has reached the position of the lower receiving end. Thus, the liquid level in the oil collection box 1 is determined based on the liquid level height of that receiving end.

[0053] In other words, this oil collection device can obtain the liquid level in the oil collection box 1 in real time, allowing users to know the amount of oil in the box promptly. This avoids situations where there is too much oil without the user's knowledge, preventing oil spills and improving the user experience. Furthermore, this oil collection device eliminates the need for visual inspection, making it more convenient to use. Moreover, by detecting the liquid level through signal transmission and reception, it is unaffected by the aging of the mechanical structure, ensuring the accuracy and reliability of the detection results.

[0054] Optionally, the signal transmitting module 21 includes an ultrasonic transmitting device, and the signal receiving module 22 includes an ultrasonic receiving device. The transmitting probe of the ultrasonic transmitting device can emit ultrasonic signals, and multiple receiving probes of the ultrasonic receiving device can receive ultrasonic signals.

[0055] In other embodiments, the signal transmitting module 21 may also be an optical signal transmitting device, and the signal receiving module 22 may be an optical signal receiving device. The optical signal may be laser, infrared light, etc.

[0056] Optionally, see Figure 2 The oil collection box 1 includes a base plate 13, a first side plate 11 and a second side plate 12 are spaced apart at both ends of the base plate 13 along the width direction, and an end plate is provided at each end of the base plate 13 along the length direction. The base plate 13, the first side plate 11, the second side plate 12 and the two end plates are arranged to form the oil collection box 1.

[0057] Optionally, see Figure 2 and Figure 3 A first receiving cavity 31 is provided on the first side plate 11. The first receiving cavity 31 is independent of the inner cavity of the oil collection box 1, and the signal transmitting module 21 is located in the first receiving cavity 31. The first receiving cavity 31 can separate the signal transmitting module 21 from the inner cavity of the oil collection box 1, prevent oil from contaminating the signal transmitting module 21, and ensure the working reliability of the signal transmitting module 21.

[0058] Optionally, see Figure 2 and Figure 3 The first side plate 11 has a first surrounding structure 3 inside the oil collection box 1, which forms a first receiving cavity 31. That is, the first receiving cavity 31 is located inside the oil collection box 1, and the signal transmitting module 21 is located inside the first side plate 11. This arrangement makes the outer side of the first side plate 11 free of protruding structures, making the outer surface of the oil collection box 1 neater and more aesthetically pleasing. When the oil collection device is installed on the mounting foundation, it saves more installation space and ensures a more beautiful appearance.

[0059] Of course, in some other embodiments, a first enclosure structure 3 may also be provided on the outside of the first side plate 11, in which case the signal transmitting module 21 is located on the outside of the first side plate 11.

[0060] See Figure 2 and Figure 3 A second receiving cavity 41 is provided on the second side plate 12. The second receiving cavity 41 is independent of the inner cavity of the oil collection box 1, and the signal receiving module 22 is located in the second receiving cavity 41. The second receiving cavity 41 can separate the signal receiving module 22 from the inner cavity of the oil collection box 1, prevent oil from contaminating the signal receiving module 22, and ensure the reliable operation of the signal receiving module 22.

[0061] Optionally, see Figure 2 and Figure 3 The second side plate 12 has a second enclosure structure 4 inside the oil collection box 1, which forms a second receiving cavity 41. That is, the second receiving cavity 41 is located inside the oil collection box 1, and the signal receiving module 22 is located inside the second side plate 12. This arrangement makes the outer side of the second side plate 12 free of protruding structures, making the outer surface of the oil collection box 1 neater and more aesthetically pleasing. When the oil collection device is installed on the mounting foundation, it saves more installation space and ensures a more beautiful appearance.

[0062] In some other embodiments, a second enclosure structure 4 may be provided on the outside of the second side plate 12, in which case the signal receiving module 22 is located on the outside of the second side plate 12.

[0063] Optionally, both the first enclosure structure 3 and the second enclosure structure 4 include a first plate 32, a second plate 33 and a third plate 34 that are bent and connected in sequence. The first plate 32, the second plate 33 and the third plate 34 form a U-shaped structure. The opening of the U-shaped structure faces the first side plate 11 or the second side plate 12, so that the first enclosure structure 3 and the first side plate 11 form a first receiving cavity 31, and the second enclosure structure 4 and the second side plate 12 form a second receiving cavity 41.

[0064] Optionally, see Figure 2 and Figure 3 The oil collection device also includes an alarm module, and both the alarm module and the detection component 2 are communicatively connected to the control system. The signal receiving module 22 includes a first receiving end 221, and the liquid level at which the first receiving end 221 is located is the first warning liquid level. When the first receiving end 221 detects that the liquid level in the oil collection box 1 has reached the first warning liquid level, the alarm module issues a first alert message. In this embodiment, the time taken for the first receiving end 221 to receive the signal is used to determine whether the liquid level in the oil collection box 1 has reached the first warning liquid level. When the liquid level reaches the first warning liquid level, the control system controls the alarm module to issue a first alert message to remind the user to take appropriate action in a timely manner.

[0065] Specifically, the time taken for the first receiving end 221 to receive the signal transmitted by the transmitting end 211 is defined as the first duration. When the first duration reaches the first preset duration, it indicates that there is already oil at the liquid level height where the first receiving end 221 is located. Therefore, it can be determined that the liquid level in the oil collection box 1 has reached the first warning liquid level. The first preset duration is a duration pre-stored in the control system, while the first actual duration is the duration actually measured. The first preset duration can be measured through prior experiments and then stored in the control system.

[0066] Optionally, the first warning level is the level at which the oil collection box 1 needs to be cleaned. For example, when the oil collection device is applied to a range hood, the alarm module includes an indicator light set on the control panel of the range hood. The first prompt information can be that the indicator light is yellow or red. When the oil level in the oil collection box 1 is detected to reach the first warning level, the control system controls the indicator light to light up to remind the user that the oil collection box 1 needs to be cleaned.

[0067] In other embodiments, the first prompt information can also be a text prompt, a voice prompt, or other similar means. The prompt method can be selected according to actual needs and is not limited to the prompt methods listed above.

[0068] Optionally, see Figure 2 and Figure 3 The signal receiving module 22 includes a second receiving end 222. The liquid level at which the second receiving end 222 is located is the second warning liquid level. When the second receiving end 222 detects that the liquid level in the oil collection box 1 has reached the second warning liquid level, the alarm module issues a second prompt message. The second warning liquid level is greater than the first warning liquid level. In this embodiment, the time taken for the second receiving end 222 to receive the signal determines whether the liquid level in the oil collection box 1 has reached the second warning liquid level. When the liquid level reaches the second warning liquid level, the control system controls the alarm module to issue the second prompt message.

[0069] Specifically, the time taken for the second receiver 222 to receive the signal transmitted by the transmitter 211 is defined as the second duration. When the second duration reaches the second preset duration, it indicates that there is already oil at the liquid level height where the second receiver 222 is located. Therefore, it can be determined that the liquid level in the oil collection box 1 has reached the second warning liquid level. Here, the second preset duration is the duration pre-stored in the control system and can be measured through previous experiments. The second duration is the actual measured duration.

[0070] Optionally, the second warning level is the maximum permissible level of the oil collection box 1. When the level in the oil collection box 1 reaches the second warning level, the oil collection box 1 must be emptied before it can be used again. For example, the alarm module includes a buzzer, and the second prompt is a buzzing sound emitted by the buzzer. When the control system detects that the level in the oil collection box 1 has reached the second warning level, it controls the buzzer to activate, reminding the user to empty the oil collection box 1 before using the fume extraction equipment, thus preventing excessive oil overflow from the oil collection box 1.

[0071] In other embodiments, the second prompt information can also be a voice prompt or the like, as long as it can serve the corresponding prompting function.

[0072] In this embodiment, taking the signal transmitting module 21 as an ultrasonic transmitting device and the signal receiving module 22 as an ultrasonic receiving device as an example, the speed of ultrasonic signal propagation in air is less than the speed of ultrasonic signal propagation in oil. The first preset duration is the time taken for the first receiving end 221 to receive the signal when the liquid level in the oil collection box 1 is at the first warning liquid level; the second preset duration is the time taken for the second receiving end 222 to receive the signal when the liquid level in the oil collection box 1 is at the second warning liquid level.

[0073] When the first duration of time used by the first receiver 221 to receive the ultrasonic signal is greater than the first preset duration, it indicates that the propagation path of the ultrasonic signal received by the first receiver 221 is entirely air. At this time, the liquid level in the oil collection box 1 has not reached the first warning liquid level. When the first duration of time used by the first receiver 221 to receive the ultrasonic signal is equal to the first preset duration, it indicates that the propagation path of the ultrasonic signal received by the first receiver 221 includes at least a portion of the liquid path. At this time, the liquid level in the oil collection box 1 reaches the liquid level height where the first receiver 221 is located, i.e., it reaches the first warning liquid level.

[0074] When the actual measured second duration of the ultrasonic signal received by the second receiver 222 is greater than the second preset duration, it indicates that the liquid level in the oil collection box 1 has not reached the second warning level. When the actual measured second duration of the ultrasonic signal received by the second receiver 222 is equal to the second preset duration, it indicates that the liquid level in the oil collection box 1 has reached the liquid level height where the second receiver 222 is located, that is, the second warning level has been reached.

[0075] When the first time taken by the first receiving end 221 to receive the ultrasonic signal is less than the first preset time, and the second time taken by the second receiving end 222 to receive the ultrasonic signal is greater than the second preset time, it indicates that the liquid path in the propagation path of the ultrasonic signal received by the first receiving end 221 has increased. That is, the liquid level in the oil collection box 1 has exceeded the first warning liquid level, but the liquid level in the oil collection box 1 has not yet reached the second warning liquid level. At this time, the liquid level in the oil collection box 1 is between the first warning liquid level and the second warning liquid level.

[0076] Optionally, see Figure 3 The second receiver 222 is located at the same level as the transmitter 211. When the liquid level in the oil collection box 1 reaches the second warning level, the propagation path of the signal received by the second receiver 222 is the liquid path, and the detection result is more accurate.

[0077] Of course, in other embodiments, the second receiving end 222 may not be flush with the transmitting end 211.

[0078] Optionally, see Figure 2 and Figure 3 The signal receiving module 22 includes a third receiving end 223, which is located above the highest liquid level in the oil collection box 1. That is, the oil in the oil collection box 1 will not reach the height of the third receiving end 223, and the propagation path of the signal received by the third receiving end 223 is always through the air. By comparing the actual time taken for the third receiving end 223 to receive the signal with the preset time stored in the control system, it can be determined whether the signal emitted by the transmitting end 211 is affected by oil contamination. If so, the preset duration of each receiving end stored in the control system can be corrected based on the change in the time taken for the third receiving end 223 to receive the signal, eliminating the influence of oil contamination and other factors on the detection results and improving the accuracy of the liquid level detection in the oil collection box 1.

[0079] Optionally, see Figure 3 The signal receiving module 22 also includes a fourth receiving end 224 and a fifth receiving end 225, which are arranged sequentially below the first receiving end 221. That is, the fourth receiving end 224 and the fifth receiving end 225 are closer to the bottom of the oil collection box 1. When the oil level in the oil collection box 1 is low, the liquid level can be determined by the time it takes for the fifth receiving end 225 to receive the signal. When the liquid level in the oil collection box 1 is slightly higher, the liquid level in the oil collection box 1 can be determined by the time it takes for the fourth receiving end 224 to receive the signal, thereby realizing the detection of different liquid level states in the oil collection box 1.

[0080] In other embodiments, the number of receivers can be increased or decreased adaptively. For example, four, six, or other numbers of receivers can be provided, but the number is not limited to those listed above. Multiple receivers can be arranged at equal or non-equal intervals along the depth direction of the oil collection box 1, and can be adjusted adaptively according to actual needs.

[0081] Optionally, see Figure 1 , Figure 2 and Figure 4 The oil collection box 1 is equipped with a connecting structure 14, which is used to connect to the installation foundation. The connecting structure 14 also has an oil guiding structure to guide the oil between the installation foundation and the connecting structure 14 into the oil collection box 1. The connecting structure 14 allows for the installation and disassembly of the oil collection device from the installation foundation, facilitating the disassembly and cleaning of the oil collection device. The oil guiding structure ensures that the oil between the connecting structure 14 and the installation foundation is promptly guided into the oil collection box 1, preventing oil from overflowing outside the oil collection box 1.

[0082] In this embodiment, see Figure 1 The fume extraction device can be a range hood, which includes a housing 10 and a fume collection hood 20. The fume collection hood 20 is connected to the housing 10 and can extend and retract into the housing 10, thus concealing the fume collection hood 20 and reducing the space occupied by the range hood when not in use. An oil collection device is installed on the fume collection hood 20, such as... Figure 1 As shown, the bottom of the fume hood 20 is provided with an oil leakage structure 201. After the oil collection device is installed on the fume hood 20, the oil leakage structure 201 is directly opposite the inner cavity of the oil collection box 1. The oil in the casing 10 and the fume hood 20 can flow from the oil leakage structure 201 into the oil collection box 1, preventing the oil from dripping onto the stove.

[0083] Optionally, see Figure 2 and Figure 4 The connecting structure 14 includes a connecting plate 141, which is located at one end of the oil collection box 1 and folds inward toward the inside of the oil collection box 1. For example, when the mounting base is a range hood hood 20, the range hood 20 has a slot, and the connecting plate 141 can be inserted into the slot to achieve a detachable connection between the oil collection device and the range hood 20. In this embodiment, a connecting plate 141 is provided at each end of the oil collection box 1 along its length, so that both ends of the oil collection box 1 can be connected to the mounting base, improving installation stability.

[0084] Furthermore, a limiting part 142 is provided at one end of the connecting plate 141. When the connecting plate 141 is inserted into the slot, the limiting part 142 can stop at one end of the slot. That is, the limiting part 142 can restrict the insertion position of the connecting plate 141 in the slot, ensuring that the oil collection box 1 can be accurately installed in place and preventing the connecting plate 141 from falling out of the slot, thereby improving the connection stability.

[0085] Optionally, see Figure 2 and Figure 4 The oil guiding structure includes an oil guiding slope 1411 disposed on the connecting plate 141, the oil guiding slope 1411 being inclined toward the interior of the oil collection box 1. When oil flows to the connecting plate 141, under the action of the oil guiding slope 1411, the oil will flow along the oil guiding slope 1411 toward the interior of the oil collection box 1, thereby preventing the oil from flowing to the outside of the oil collection box 1. Exemplarily, the connecting plate 141 is inclined toward the interior of the oil collection box 1 as a whole, so that the oil guiding slope 1411 is formed on the upper surface of the connecting plate 141 (see reference). Figure 4 (location within).

[0086] Optionally, see Figure 2 and Figure 4 The oil guiding structure includes an oil guiding groove 1412 disposed on the connecting plate 141, which connects to the inner cavity of the oil collection box 1. Oil flowing onto the connecting plate 141 can enter the oil collection box 1 through the oil guiding groove 1412, preventing excessive oil accumulation on the connecting plate 141 from overflowing onto the outer surface of the oil collection box 1, thereby preventing oil from dripping onto the stove area.

[0087] For example, the oil guide groove 1412 is a strip-shaped groove formed in the connecting plate 141, with one end extending to the edge of the connecting plate 141 to communicate with the interior of the oil collection box 1. In other embodiments, the oil guide groove 1412 may also be a recessed groove in the middle region of the connecting plate 141, with a flow port formed on one side of the groove, communicating with the interior of the oil collection box 1. Oil can be collected in the groove, and then the oil enters the oil collection box 1 through the flow port, thus realizing oil flow.

[0088] In some embodiments, an oil guiding slope 1411 and an oil guiding groove 1412 can be provided on the connecting plate 141 at the same time to ensure that all the oil on the connecting plate 141 can enter the oil collection box 1, thereby improving the oil guiding effect.

[0089] In some embodiments, only the oil guiding slope 1411 may be provided on the connecting plate 141. Alternatively, only the oil guiding groove 1412 may be provided on the connecting plate 141.

[0090] This embodiment also provides a range hood, including a housing and the aforementioned oil collection device, which is installed on the housing. The oil collection device is used to collect the oil produced by the range hood, preventing oil from dripping onto the stove or floor and reducing cleaning frequency. The range hood can be a range hood, integrated stove, or other device with a range hood function.

[0091] The fume extraction device provided in this embodiment, after adopting the aforementioned oil collection device, can obtain the liquid level in the oil collection box 1 in real time. This allows users to promptly know the amount of oil in the oil collection box 1, avoiding situations where there is too much oil without the user's knowledge, preventing oil overflow, and thus improving the user experience. Furthermore, it eliminates the need for users to visually observe the oil level, making it more convenient to use. Moreover, the liquid level detection method, which uses signal transmission and reception, is unaffected by the aging of the mechanical structure, ensuring the accuracy and reliability of the detection results.

[0092] like Figure 1 As shown, the fume extraction device can be a range hood, which includes a casing 10 and a fume collection hood 20. The fume collection hood 20 is connected to the casing 10. The casing includes the fume collection hood 20, and an oil collection device is installed on the fume collection hood 20. Figure 1 As shown, the bottom of the fume hood 20 is provided with an oil leakage structure 201. After the oil collection device is installed on the fume hood 20, the oil leakage structure 201 is directly opposite the inner cavity of the oil collection box 1. The oil in the casing 10 and the fume hood 20 can flow from the oil leakage structure 201 into the oil collection box 1, preventing the oil from dripping onto the stove.
