Description

Technical Field

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

[0002] During the extraction of cooking fumes, household range hoods separate the oil mist from the fumes into oil droplets. These droplets adhere to the oil filter and slide down into the oil cup for temporary storage. Once the oil cup reaches a certain level, it needs to be disassembled to empty the waste oil. Traditional oil cups are usually installed on the oil filter using detachable connections such as clips. However, these clip-on connections often create hard-to-clean corners. When waste oil gets into these corners, it becomes very difficult to clean. Over time, the waste oil will turn black or yellow and produce an odor, significantly impacting the user experience. In addition, disassembling the clip-on connection usually requires the operator to use force to pry the oil cup, which is laborious and easily gets the operator's hands dirty. Utility Model Content

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] like Figure 2 , Figure 3 , Figure 4 As shown, this application provides an oil cup connection structure 100, including a first connection structure 11 and a second connection structure 12. The first connection structure 11 and the second connection structure 12 are respectively used to connect to the oil cup 300 and the oil mesh 200. The first connection structure 11 and the second connection structure 12 are mutually matched and can be quickly connected and disassembled. In this way, when the waste oil inside the oil cup 300 reaches the upper limit and the oil cup 300 needs to be disassembled, the oil cup 300 can be quickly removed from the oil mesh 200 by utilizing the quick connection and disassembly effect of the first connection structure 11 and the second connection structure 12. After cleaning, the oil cup 300 can also be quickly assembled back onto the oil mesh 200, which is very convenient and quick.

[0033] The technical details of each component will be introduced below.

[0034] In some implementations, such as Figure 3 , Figure 4 As shown, the first connection structure 11 includes a suction member 111 and an adjusting member 112. The suction member 111 is connected to the adjusting member 112, and the adjusting member 112 is used to control the suction member 111 to be in a magnetic or non-magnetic state. The second connection structure 12 is made of magnetic material (it should be noted that magnetic material refers to materials such as iron and nickel that can be attracted by a magnetic field).

[0035] When the suction component 111 is in a magnetic state, the second connecting structure 12 can magnetically attract the first connecting structure 11, thereby allowing the oil cup 300 to be fixed to the oil mesh 200 by magnetic attraction. When removing the oil mesh 200, the suction component 111 is controlled by the adjusting component 112 to change from a magnetic state to a non-magnetic state. At this time, since the suction component 111 loses its magnetism, there is no magnetic force between the second connecting structure 12 and the suction component 111. Under the action of gravity, the oil cup 300 will detach from the oil mesh 200. At this time, it is only necessary to support the oil cup 300 from below, or let the oil cup 300 fall naturally to other containers. The disassembly process does not require the operator to grab it forcefully, saving time and effort. Moreover, compared with the traditional snap-fit ​​connection method, the above-mentioned magnetic connection structure greatly reduces the dead corners in shape, and can even be made without dead corners, making it convenient for the operator to clean and wipe the oil cup 300 and the oil mesh 200. Accordingly, when installing the oil cup 300, the adjusting component 112 only needs to control the suction component 111 to change from a non-magnetic state to a magnetic state. Since the suction component 111 is magnetic, when the second connecting structure 12 contacts the suction component 111, it will be attracted to the suction component 111, thus fixing the oil cup 300 to the oil mesh 200. The installation process does not require the operator to grasp or pry; quick fixing can be achieved through simple contact, which is very convenient. In summary, the oil cup connecting structure 100 provided in this application, through magnetic connection, makes the disassembly and installation process between the oil cup 300 and the oil mesh 200 much more convenient.

[0036] It is understood that the aforementioned suction element 111 can be an electromagnet. The power supply to the suction element 111 is controlled by the adjusting element 112 to control whether the suction element 111 possesses magnetism. When disassembling the oil cup 300, the power supply to the suction element 111 is disconnected, causing the suction element 111 to lose its magnetism. Consequently, the magnetic force between the suction element 111 and the second connecting structure 12 disappears, and the oil cup 300 can then detach from the oil mesh 200. Correspondingly, when installing the oil cup 300, the power supply to the suction element 111 is connected, making the suction element 111 magnetic. The oil cup 300 is then installed onto the oil mesh 200 through the magnetism between the second connecting structure 12 and the suction element 111. During the above installation and disassembly process, the operator does not need to forcefully grasp or pry the oil cup 300, saving time and effort, and the disassembly and installation process is very convenient.

[0037] In some implementations, such as Figure 3 , Figure 4 , Figure 5As shown, the aforementioned adjusting component 112 includes a permanent magnet 02 and a lifting assembly 01. The lifting assembly 01 is connected to the permanent magnet 02, and the permanent magnet 02 can selectively connect to the attracting component 111. The permanent magnet 02 can move from a first predetermined position to a second predetermined position following the lifting assembly 01. When the permanent magnet 02 is in the first predetermined position, the permanent magnet 02 is connected to the attracting component 111, and the attracting component 111 is in a magnetic state. When the permanent magnet 02 is in the second predetermined position, the permanent magnet 02 is disengaged from the attracting component 111, and the attracting component 111 is in a non-magnetic state. (It should be noted that the attracting component 111 itself is made of a non-magnetic material, such as iron or nickel. When the attracting component 111 and the permanent magnet 02 come into contact, the attracting component 111 will also become magnetic.) The above design controls the presence or absence of magnetism in the attracting component 111 through forceful contact, eliminating the need for continuous power supply to maintain its magnetism. This allows the oil cup 300 to magnetically connect with the oil mesh 200 without power, while also reducing energy consumption. Specifically, when disassembling the oil cup 300, the permanent magnet 02 is moved to the second predetermined position via a lifting mechanism. At this point, the attracting component 111 is detached from the permanent magnet 02, the attracting component 111 is not magnetic, and the oil cup 300 is separated from the oil mesh 200. When installing the oil cup 300, the permanent magnet 02 is moved to the first predetermined position via the lifting mechanism. At this point, the permanent magnet 02 and the attracting component 111 are in magnetic contact, so that the attracting component 111 is magnetic, and the oil cup 300 can be magnetically connected to the oil mesh 200 through the second connecting structure 12.

[0038] Furthermore, the first connecting structure 11 may experience a decrease in magnetism due to prolonged use. To address this issue, the permanent magnet 02 is detachably connected to the lifting end of the lifting assembly 01. When the first connecting structure 11 experiences a decrease in magnetism, only the original permanent magnet 02 needs to be replaced. In practical applications, the permanent magnet 02 is relatively inexpensive, resulting in low replacement costs and reducing maintenance costs for users.

[0039] In some implementations, such as Figure 3 , Figure 4 , Figure 5 As shown, the second connecting structure 12 is a thin sheet structure, which is used to adhere and fix to the bottom surface of the oil cup 300 on the side opposite to the oil mesh 200. Since the second connecting structure 12 needs to be magnetically attracted to the suction member 111, the second connecting structure 12 needs to be made of magnetic material (it should be noted that magnetic material refers to materials such as iron and nickel that can be attracted by a magnetic field). The thin sheet structure has little impact on the flatness of the bottom surface of the oil cup 300, and the flatness of the bottom surface of the oil cup 300 makes it easier for the operator to wipe and clean the bottom surface of the oil cup 300.

[0040] In other implementations, such as Figure 5As shown, the second connecting structure 12 is embedded in the bottom surface of the oil cup 300, and the side of the second connecting structure 12 near the oil mesh 200 coincides with the bottom surface of the oil cup 300. With the above design, after the second connecting structure 12 is embedded in the bottom surface of the oil cup 300, it will not affect the flatness of the bottom surface and will not cause inconvenience to the operator's wiping and cleaning.

[0041] In other embodiments, the second connecting structure 12 is used to encapsulate the interior of the oil cup 300. In practical applications, since the second connecting structure 12 is usually made of metal, it is prone to corrosion when exposed to air for a long time, which negatively affects the stability of the magnetic attraction between the second connecting structure 12 and the attractor 111. By encapsulating the second connecting structure 12 inside the oil cup 300, the second connecting structure 12 is isolated from the air, thus preventing corrosion. After the second connecting structure 12 is encapsulated inside the oil cup 300, the side of the second connecting structure 12 closest to the bottom surface of the oil cup 300 opposite to the oil mesh 200 reduces the thickness of the oil cup 300 material between the second connecting structure 12 and the attractor 111 when they are attracted, ensuring the strength of the magnetic attraction between the second connecting structure 12 and the attractor 111.

[0042] In addition to the effects mentioned above, the encapsulation of the second connecting structure 12 inside the oil cup 300 can also prevent the second connecting structure 12 from detaching from the oil cup 300 during impacts, greatly improving the stability of the second connecting structure 12 on the oil cup 300.

[0043] like Figure 1 , Figure 2 As shown, the range hood provided in this application includes the aforementioned oil cup connecting structure 100, oil mesh 200, and oil cup 300, with the oil mesh 200 and oil cup 300 interconnected via the oil cup connecting structure 100. Under the action of the oil cup connecting structure 100, the oil cup 300 of the range hood can be disassembled and installed without the operator needing to forcefully grasp or pry it. Furthermore, since the oil cup connecting structure 100 uses a contact magnetic attraction method for connection and fixation, the connecting structure does not produce any corner structures, and the surface of the oil cup 300 is smooth and easy to wipe clean.

[0044] In some implementations, such as Figure 3 , Figure 4 , Figure 5As shown, the range hood also includes a sensor 400 and an alarm device. The sensor 400 is electrically connected to the alarm device. The sensor 400 is located on the side of the oil filter 200 opposite the oil cup 300. The sensor 400 is used to monitor the oil level inside the oil cup 300. When the amount of oil remaining inside the oil cup 300 reaches a predetermined level, the oil level rises to the predetermined position. At this time, the sensor 400 will detect that the oil level has reached the predetermined position and will send a signal to the alarm device. After receiving the signal from the sensor 400, the alarm device will sound an alarm to remind the operator that there is too much oil inside the oil cup 300 and that it needs to be cleaned in time to prevent waste oil from overflowing.

[0045] In some implementations, such as Figure 6 , Figure 7 As shown, a gap 001 is formed between the oil mesh 200 and the oil cup 300; the range hood also includes a sealing element 600, which surrounds the oil cup 300 and covers the gap 001. One side of the sealing element 600 is sealed to the oil cup 300, and the other side is sealed to the oil mesh 200.

[0046] In practical applications, the aforementioned sealing element 600 can be made of elastic materials such as silicone or rubber. During the use of the range hood, fumes will enter between the oil cup 300 and the oil filter 200 through the gap 001. Since the sensor 400 is positioned relative to the oil cup 300, if fumes enter between the oil cup 300 and the oil filter 200, it will interfere with the sensor 400, affecting its monitoring of the waste oil level inside the oil cup 300. This may result in the range hood being unable to promptly detect the oil level inside the oil cup 300, leading to waste oil overflowing from the oil cup 300. With the sealing element 600 installed, it can cover and block the gap 001, preventing fumes from entering between the oil cup 300 and the oil filter 200 and affecting the sensor 400's detection. This allows the sensor 400 to accurately monitor the oil level inside the oil cup 300 and promptly remind the user when the waste oil is full and to replace it.

[0047] Furthermore, the aforementioned seal 600 is detachably fitted onto the edge of the oil cup 300, thus facilitating separate cleaning of the oil cup 300 and the seal 600.

[0048] In some implementations, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the range hood also includes a protective cover 500, which is sealed to the oil filter 200 and covers the first connecting structure 11.

[0049] In practical applications, oil fumes will enter the interior of the oil mesh 200. The protective cover 500 can protect the first connecting structure 11, prevent oil fumes from adhering to the surface of the first connecting structure 11 and affecting the operation of the first connecting structure 11, thereby extending the service life of the first connecting structure 11.
