When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0047] This application proposes a desktop range hood, combined with Figures 1 to 8 , Fig.11 as well as Figures 14 to 16 As shown, in some embodiments, the desktop hood includes an air duct housing 1100 and a filter component 1400, and the filter component 1400 is used to filter oil smoke, wherein the air duct housing 1100 is provided with a first magnetic attraction portion 1130 and a first connecting portion 1120, and the filter component 1400 is provided with a second magnetic attraction portion 1440 and a second connecting portion 1430, and the first connecting portion 1120 and the second connecting portion 1430 are used for plug-in connection, and the first magnetic attraction portion 1130 and the second magnetic attraction portion 1440 are used for magnetic connection, so as to realize the detachable connection between the filter component 1400 and the air duct housing 1100. The plug-in connection between the first connecting portion 1120 and the second connecting portion 1430 can realize the rapid positioning of the filter component 1400, and then the magnetic connection between the first magnetic attraction portion 1130 and the second magnetic attraction portion 1440 can realize further fixation, and the structure is simple, which effectively improves the convenience of disassembly and assembly of the filter component 1400.

[0048] Specifically, the desktop range hood includes a range hood body 1000 and a body 2000. The range hood body 1000 is installed on the body 2000. The desktop range hood is placed on the desktop through the body 2000, so that the range hood body 1000 is a certain distance away from the desktop. The assembly between the range hood body 1000 and the body 2000 can be referred to the relevant technology. It is not an improvement of the present application and will not be described in detail.

[0049] The range hood body 1000 includes an air duct housing 1100, a bracket 1200, a fan 1300 and a filter component 1400. The air duct housing 1100 is provided with an air duct 1110, which can be integrally formed or formed by connecting at least two components, one end of the air duct 1110 forms an air inlet 1111, and the other end of the air duct 1110 forms an air outlet 1112. The bracket 1200 is arranged in the air duct 1110, and needs to be connected to the air duct shell 1100 so as to be fixed in the air duct 1110. There are various ways to connect the bracket 1200 and the air duct shell 1100, such as welding, screwing, clamping, etc. It can be understood that the bracket 1200 is a component used to support other components. The bracket 1200 can be made of metal materials or other materials. The bracket 1200 can be a regular shape or an irregular shape. In the present embodiment, the bracket 1200 is a sheet metal part, and the so-called sheet metal part is processed by sheet metal technology. The fan 1300 is connected to the bracket 1200 and fixed to the bracket 1200. At this time, the fan 1300 is located upstream of the bracket 1200 and between the air inlet 1111 and the air outlet 1112. The upstream here refers to the upstream of the flow of oil smoke. The fan 1300 drives the oil smoke from the air inlet 1111 into the air duct 1110 and is discharged from the air outlet 1112. The oil smoke first flows through the fan 1300 and then flows through the bracket 1200. The filter component 1400 is installed on the air duct housing 1100 and arranged in the air duct 1110. The filter component 1400 is arranged upstream of the fan 1300 (such as the filter component 1400 is arranged at the air inlet 1111). The air flow first flows through the filter component 1400 and then flows through the fan 1300. By arranging the filter component 1400, the filter component 1400 can filter the oil smoke to obtain oil liquid.

[0050] It is understandable that the filter component 1400 will accumulate dirt and even become clogged after being used for a period of time, so the filter component 1400 needs to be disassembled for cleaning. In the related art, the filter component 1400 is fixed to the air duct shell 1100 by screwing, that is, when the filter component 1400 is installed in the air duct shell 1100, it is necessary to screw it, and when the filter component 1400 is removed from the air duct shell 1100, the screw needs to be loosened. The screwing operation requires the user to control the screwdriver to turn the screw, and the disassembly and assembly experience of this method needs to be improved. For this reason, in this embodiment, the first connecting part 1120 is provided to cooperate with the second connecting part 1430, and the first magnetic part 1130 is provided to cooperate with the second magnetic part 1440 to solve the problem.

[0051] When the filter component 1400 is installed to the air duct shell 1100, the second connection part 1430 is controlled to cooperate with the first connection part 1120. The cooperation between the second connection part 1430 and the first connection part 1120 is realized in the form of a plug-in connection. The second connection part 1430 can be inserted into the first connection part 1120, or the first connection part 1120 can be inserted into the second connection part 1430. As long as one of the first connection part 1120 and the second connection part 1430 is inserted into the other of the first connection part 1120 and the second connection part 1430, quick positioning can be achieved. It is convenient and quick. For example, the first connection part 1120 is a socket, and the second connection part 1430 is inserted into the socket to realize a quick plug-in connection.

[0052] Based on the plug-in connection between the first connecting portion 1120 and the second connecting portion 1430, the second magnetic attraction portion 1440 is controlled to cooperate with the first magnetic attraction portion 1130, and the cooperation between the second magnetic attraction portion 1440 and the first magnetic attraction portion 1130 is realized in the form of magnetic attraction connection. The first magnetic attraction portion 1130 may generate a magnetic field to attract the second magnetic attraction portion 1440, or the second magnetic attraction portion 1440 may generate a magnetic field to attract the first magnetic attraction portion 1130, or the first magnetic attraction portion 1130 and the second magnetic attraction portion 1440 may generate a magnetic field to attract the first magnetic attraction portion 1130. They generate magnetic fields respectively and attract each other. On the basis of the plug-in connection between the first connecting part 1120 and the second connecting part 1430, the magnetic connection between the first magnetic part 1130 and the second magnetic part 1440 can be achieved by controlling the first magnetic part 1130 and the second magnetic part 1440 to be close to each other. It is convenient and quick. For example, the first magnetic part 1130 is a magnet and the second magnetic part 1440 is also a magnet. In this way, the first magnetic part 1130 and the second magnetic part 1440 generate magnetic fields respectively to improve the attraction force of the magnetic connection.

[0053] It is through the cooperation between the plug-in connection and the magnetic connection that the removal of the filter component 1400 becomes very convenient. When removing the filter component 1400 from the air duct housing 1100, the user grabs the filter component 1400 and applies force. The force applied by the user overcomes the attraction between the first magnetic attraction part 1130 and the second magnetic attraction part 1440, so that the first magnetic attraction part 1130 and the second magnetic attraction part 1440 are separated, and then the second connection part 1430 is controlled to move in the opposite direction of the insertion direction to disengage from the first connection part 1120, so that the removal of the filter component 1400 is completed, and the filter component 1400 is convenient for cleaning.

[0054] Combination Fig.14 , Fig.15 and Fig.16As shown, in some embodiments, the second connecting portion 1430 is disposed on one side of the center of the filter component 1400 and the second magnetic portion 1440 is disposed on the other side of the center of the filter component 1400. In this way, when the filter component 1400 is installed to the air duct shell 1100, connection points are formed on opposite sides of the center of the filter component 1400, thereby improving the installation stability of the filter component 1400.

[0055] With the air inlet 1111 of the desktop range hood facing the user as a reference, the side of the desktop range hood facing the user (i.e., the direction where the air inlet 1111 is located) is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the user's right hand is the right, the side close to the desktop is the bottom, and the side away from the desktop is the top. The positions of the second connecting portion 1430 and the second magnetic portion 1440 are set as follows: the second connecting portion 1430 can be set on the left side of the filter component 1400 and the second magnetic portion 1440 can be set on the right side of the filter component 1400, the second connecting portion 1430 can be set on the right side of the filter component 1400 and the second magnetic portion 1440 can be set on the left side of the filter component 1400, or the second connecting portion 1430 can be set on the upper side of the filter component 1400 and the second magnetic portion 1440 can be set on the lower side of the filter component 1400. It can be understood that no matter where the second connection portion 1430 and the second magnetic attraction portion 1440 are disposed, the first connection portion 1120 and the first magnetic attraction portion 1130 need to be disposed correspondingly.

[0056] Continue to combine Fig.14 , Fig.15 and Fig.16 As shown, in some embodiments, the second connection portion 1430 is arranged on the lower side of the filter component 1400 and the second magnetic attraction portion 1440 is arranged on the upper side of the filter component 1400. When the filter component 1400 is installed on the air duct housing 1100, the second connection portion 1430 is first controlled to be plugged and connected with the first connection portion 1120. Since the second connection portion 1430 is located on the lower side of the filter component 1400, the user can easily observe the relative position of the second connection portion 1430 and the first connection portion 1120, thereby facilitating the control. The second connection part 1430 is controlled to cooperate with the first connection part 1120. After the second connection part 1430 is plugged and connected with the first connection part 1120, the filter component 1400 can be stopped on the air duct shell 1100 under the force applied by the user and gravity, and the air duct shell 1100 is not easy to loosen. The upper side of the filter component 1400 is continued to be controlled to rotate toward the air duct shell 1100, so that the second magnetic attraction part 1440 gradually approaches the first magnetic attraction part 1130 until it is attracted, thereby further improving the convenience of disassembly and assembly.

[0057] Combination Figure 6 , Figure 8 , Fig.14 , Fig.15 and Fig.17 As shown, in some embodiments, based on the first connection part 1120 being a socket and the second connection part 1430 being inserted into the socket, the second connection part 1430 is provided with an oil drain port 1431, and the filter component 1400 is used to discharge oil through the oil drain port 1431, and the desktop range hood also includes an oil cup 2400, which is configured to be detachable, and the oil cup 2400 is used to receive the oil discharged from the oil drain port 1431.

[0058] Specifically, when the tabletop hood is sucking out oil smoke, the oil smoke is filtered by the filter component 1400, and oil is generated on the filter component 1400. The oil is a complex mixture, including various organic substances and water. The oil flows downward along the filter component 1400 under the action of gravity. Based on the second connection part 1430 being inserted into the first connection part 1120 (socket), the oil discharge port 1431 is provided in the second connection part 1430, and the oil is discharged through the oil discharge port 1431 and discharged into the oil cup 2400, and is temporarily stored by the oil cup 2400. When the oil is discharged from the oil discharge port 1431, it can flow into the socket (i.e., contact the socket) and flow along the socket and be discharged from the socket, or it can be that the oil does not contact the socket when it is discharged from the oil discharge port 1431 and directly passes through the socket.

[0059] The oil cup 2400 receives the oil discharged from the oil discharge port 1431, which may be direct or indirect. The setting of the oil cup 2400 realizes temporary storage of the oil. In this embodiment, the oil cup 2400 is designed to be detachable. When the desktop range hood is in use, the oil generated by the desktop range hood is temporarily stored in the oil cup 2400. When the oil cup 2400 needs to be cleaned, the oil cup 2400 can be removed from the desktop range hood so that the oil can be poured out. After cleaning the oil cup 2400, the oil cup 2400 can be installed back into the desktop range hood.

[0060] Combination Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, in some embodiments, the desktop range hood includes a second guide member 2200, which is provided with a guide slope 2230 and a second outlet 2220. The second guide member 2200 is used to receive the oil discharged from the oil outlet 1431 through the guide slope 2230, and the second guide member 2200 discharges the oil through the second outlet 2220.

[0061] By setting the second guide member 2200, the second guide member 2200 guides the oil discharged from the oil outlet 1431 to the oil cup 2400, and the oil cup 2400 temporarily stores the oil. The second guide member 2200 is provided with a guide slope 2230. In the process of guiding the oil to the oil cup 2400, the guide slope 2230 has a buffering effect on the transmission of the oil, thereby preventing the oil from splashing during the flow and better collecting the oil.

[0062] The second guide member 2200 is used to receive the oil discharged from the oil outlet 1431, that is, the oil discharged from the oil outlet 1431 enters the second guide member 2200, is guided by the second guide member 2200, and then is discharged through the second outlet 2220 of the second guide member 2200. The second guide member 2200 receives the oil discharged from the oil outlet 1431, and may receive it directly (the oil discharged from the oil outlet 1431 directly enters the second guide member 2200) or indirectly (the oil discharged from the oil outlet 1431 indirectly enters the second guide member 2200).

[0063] The oil cup 2400 is provided with an oil collecting chamber 2410 , and the oil discharged from the second outlet 2220 enters the oil collecting chamber 2410 for temporary storage. The oil discharged from the second outlet 2220 may enter the oil collecting chamber 2410 directly or indirectly.

[0064] It is understandable that when a large amount of oil is formed in a short time, the flow of the oil may splash, especially when the oil enters the oil collecting chamber 2410, splashing is more likely to occur, and the splashed oil adheres to the inner wall of the oil cup 2400 (the cavity wall of the oil collecting chamber 2410) and easily pollutes the installation environment of the oil cup 2400. In this embodiment, the oil is guided by providing a second guide member 2200 between the oil discharge port 1431 and the oil cup 2400, and the second guide member 2200 is provided with a guide slope 2230, which may be a plane or a curved surface, and the so-called "slant" is relative to the horizontal plane. In this way, when a large amount of oil is formed in a short time, the guide slope 2230 can buffer the oil when receiving the oil, so that the oil flows slowly, and the oil splashing can be effectively avoided.

[0065] Combination Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10As shown, in some embodiments, the desktop range hood also includes a first air guide 2100, the air duct shell 1100 and the first air guide 2100 are connected and fixed by connecting means, and the first air guide 2100 is provided with a first inlet 2110 for receiving the oil discharged from the oil drain port 1431. When projected in a top-down direction, the projection of the socket (first connecting portion 1120) and / or the oil drain port 1431 is located within the contour range of the first inlet 2110.

[0066] The first guide member 2100 is used to receive the oil discharged from the oil outlet 1431, that is, the oil discharged from the oil outlet 1431 enters the first guide member 2100, is guided by the first guide member 2100, and then is discharged through the first outlet 2120 of the first guide member 2100. The first guide member 2100 receives the oil discharged from the oil outlet 1431, and may receive the oil directly (the oil discharged from the oil outlet 1431 directly enters the first guide member 2100) or indirectly (the oil discharged from the oil outlet 1431 indirectly enters the first guide member 2100). For example, the first guide member 2100 is arranged below the oil drain port 1431 and the socket (the first connecting part 1120), and the oil discharged from the oil drain port 1431 enters the first guide member 2100 under the action of gravity. The first guide member 2100 guides the oil entering it, and the oil continues to flow under the action of gravity and then discharges the first guide member 2100 through the first outlet 2120.

[0067] The first guide member 2100 is provided with a first outlet 2120, through which the first guide member 2100 discharges oil, and the second guide member 2200 is used to receive the oil discharged from the first outlet 2120 through the guide slope 2230, that is, the oil discharged from the first outlet 2120 enters the second guide member 2200, is guided by the second guide member 2200, and then is discharged through the second outlet 2220 of the second guide member 2200. The second guide member 2200 receives the oil discharged from the first outlet 2120, and may receive it directly (the oil discharged from the first outlet 2120 directly enters the second guide member 2200) or indirectly (the oil discharged from the first outlet 2120 indirectly enters the second guide member 2200). For example, the second guide member 2200 is arranged below the first outlet 2120. The oil discharged from the first outlet 2120 enters the second guide member 2200 under the action of gravity and is received by the guide slope 2230. The second guide member 2200 buffers and guides the oil entering it. The oil continues to flow under the action of gravity and then discharges from the second guide member 2200 through the second outlet 2220.

[0068] The air duct housing 1100 and the first air guide 2100 are separate components and need to be connected and fixed together by connecting means. Compared with designing the first air guide 2100 and the air duct housing 1100 as an integrally formed structure, by designing the air duct housing 1100 and the first air guide 2100 as separate components, the manufacturing difficulty of the air duct housing 1100 and the first air guide 2100 can be effectively reduced. The connecting means is a way of connecting and fixing at least two components, such as screw connection, clamping connection, welding, etc. In this embodiment, the first air guide 2100 can be fixed to the air duct housing 1100 by screw connection.

[0069] In order to minimize the leakage of oil when it enters the first guide member 2100 from the oil drain port 1431, the first guide member 2100 is provided with a first inlet 2110, and the projection of the oil drain port 1431 and / or the socket (first connecting portion 1120) is located within the contour range of the first inlet 2110 when projected in a top-down direction. That is to say, the first guide member 2100 is located below the oil drain port 1431 and the socket (first connecting portion 1120), and the first inlet 2110 is larger than the oil drain port 1431 and / or the socket. By such a configuration, when the oil is discharged from the oil drain port 1431, it falls to the first guide member 2100 under the action of gravity, and is not easy to leak out from between the oil drain port 1431 and the first inlet 2110 or from between the socket (first connecting portion 1120) and the first inlet 2110. By such a configuration, oil leakage can be prevented without sealing.

[0070] The same is true for the cooperation between the first guide member 2100 and the second guide member 2200. Figure 6 and Figure 8 As shown, in some embodiments, the second guide member 2200 is provided with a second inlet 2210, and the projection of the first outlet 2120 is set within the contour range of the second inlet 2210 when projected in a top-down direction. That is to say, the second guide member 2200 is located below the first outlet 2120, and the second inlet 2210 is larger than the first outlet 2120. By such a configuration, when the oil is discharged from the first outlet 2120 and falls to the second guide member 2200 under the action of gravity, it is not easy to leak out from between the first outlet 2120 and the second inlet 2210. By such a configuration, leakage of oil can be prevented without sealing between the first guide member 2100 and the second guide member 2200.

[0071] Combination Figure 6 As shown, in some embodiments, the first outlet 2120 is designed to be inserted into the second inlet 2210 , and the first flow guide 2100 is designed to be arranged alternately with the second flow guide 2200 .

[0072] Specifically, the first outlet 2120 is inserted into the second inlet 2210, that is, the end of the first guide member 2100 where the first outlet 2120 is located is inserted into the end of the second guide member 2200 where the second inlet 2210 is located, so that the first outlet 2120 is located within the contour range of the second inlet 2210. When the oil is discharged from the first outlet 2120 and enters the second guide member 2200, it is not easy to leak between the first outlet 2120 and the second inlet 2210.

[0073] As can be seen from the above, the first flow guide 2100 and the second flow guide 2200 need to cooperate with each other to guide the oil discharged from the oil drain port 1431 to the oil cup 2400. Assuming that the relative positions of the oil drain port 1431 and the oil cup 2400 remain unchanged, the first flow guide 2100 and the second flow guide 2200 are designed to be plug-in (the first outlet 2120 is inserted into the second inlet 2210), and the first flow guide 2100 and the second flow guide 2200 are alternately arranged, so the second inlet 2210 is much larger than the first outlet 2120. During assembly, the first flow guide 2100 and the second flow guide 2200 are easier to cooperate with each other and less likely to interfere with each other, thereby facilitating assembly and improving efficiency.

[0074] In addition, through the above arrangement, when the range hood body 1000 is designed to be swingable relative to the body 2000 , the first air guide 2100 moves accordingly and can ensure communication with the second air guide 2200 .

[0075] Combination Figure 5 , Figure 6 , Fig. 9 , Fig.10 , Fig.12 and Fig.13 As shown, in some embodiments, the desktop range hood further includes a mounting base 2300, the mounting base 2300 is provided with a receiving chamber 2320, and the oil cup 2400 is detachably arranged in the receiving chamber 2320. The mounting base 2300 is a part of the body 2000 of the desktop range hood, and is used for the installation and positioning of the oil cup 2400. The oil cup 2400 is installed in the receiving chamber 2320 so as to receive oil. When the oil received by the oil cup 2400 reaches a certain amount, the user can remove the oil cup 2400 from the receiving chamber 2320 for cleaning, and then reinstall it in the receiving chamber 2320 after cleaning.

[0076] The oil cup 2400 receives the oil by providing an oil guide oil path 2310 on the mounting seat 2300. The oil guide oil path 2310 is used to receive the oil discharged from the second outlet 2220. The oil guide oil path 2310 is provided with an oil outlet 2312. The oil guide oil path 2310 discharges the oil through the oil outlet 2312. It can be understood that the oil guide oil path 2310 can directly receive the oil discharged from the second outlet 2220, or can indirectly receive the oil discharged from the second outlet 2220. The oil cup 2400 is provided with an oil collecting chamber 2410. The oil discharged from the oil outlet 2312 enters the oil collecting chamber 2410. Specifically, the oil discharged from the second outlet 2220 enters the oil guide oil path 2310, and then finally enters the oil collecting chamber 2410 through the oil outlet 2312.

[0077] For example, the mounting seat 2300 is located below the second outlet 2220, the second outlet 2220, the oil receiving port 2311 and the oil outlet 2312 are arranged from top to bottom, the oil outlet 2312 is connected to the accommodating chamber 2320, and when the oil cup 2400 is installed in the accommodating chamber 2320, the oil outlet 2312 and the oil collecting chamber 2410 are connected, and the oil discharged from the second outlet 2220 falls into the oil guide path 2310 through the oil receiving port 2311 under the action of gravity, and the oil continues to flow under the action of gravity and is then discharged from the oil outlet 2312 until it falls into the oil collecting chamber 2410.

[0078] Combination Fig. 9 As shown, in some embodiments, the oil guide oil path 2310 is provided with an oil receiving port 2311, and the projection of the second outlet 2220 is located within the contour range of the oil receiving port 2311 when projected in the top-down direction, that is, the oil guide oil path 2310 is located below the second outlet 2220, and the oil receiving port 2311 is larger than the second outlet 2220. By such a configuration, when the oil is discharged from the second outlet 2220 and falls to the oil guide oil path 2310 under the action of gravity, it is not easy to leak out from between the second outlet 2220 and the oil receiving port 2311. For example, the second outlet 2220 can be inserted into the oil receiving port 2311, that is, the end of the second outlet 2220 of the second flow guide 2200 is inserted into the end of the oil receiving port 2311 of the mounting seat 2300, so that the second outlet 2220 can be ensured to be within the range of the oil receiving port 2311, and the connection stability between the second flow guide 2200 and the mounting seat 2300 can be improved. By configuring in this way, leakage of oil can be prevented without performing sealing treatment between the second flow guide member 2200 and the mounting seat 2300 .

[0079] The same is true for the cooperation between the oil outlet 2312 and the oil collecting chamber 2410. Figure 6 , Fig.10 , Fig.12 and Fig.13As shown, along the top-down direction, the projection of the oil outlet 2312 is set within the contour range of the oil collecting chamber 2410, that is, the oil collecting chamber 2410 is located below the oil outlet 2312, and the oil collecting chamber 2410 is larger than the oil outlet 2312, preventing oil from leaking out from between the oil outlet 2312 and the oil collecting chamber 2410.

[0080] Combination Fig.14 , Fig.15 and Fig.17 As shown, in some embodiments, the filter component 1400 includes a filter 1410 and a filter frame 1420, wherein the filter frame 1420 is provided with an oil collecting tank 1427, the second connecting portion 1430 is provided on the filter frame 1420 and the oil drain port 1431 is connected to the oil collecting tank 1427, and the filter 1410 is provided on the filter frame 1420 and is located in the oil collecting tank 1427.

[0081] Specifically, the filter frame 1420 is the skeleton structure of the filter component 1400, which is used to support the filter 1410. The filter 1410 is arranged on the filter frame 1420 to be supported. The filter 1410 is a porous structure, which can not only allow oil smoke to flow through but also filter the oil smoke to obtain oil liquid. In this embodiment, the filter frame 1420 is provided with an oil collecting groove 1427, and the filter 1410 is located in the oil collecting groove 1427, and the oil collecting groove 1427 surrounds the filter 1410. When the filter 1410 filters the oil smoke to obtain oil liquid, the oil liquid flows along the filter 1410 until it enters the oil collecting groove 1427. Through the setting of the oil collecting groove 1427, the oil liquid separated from the filter 1410 is collected and then discharged through the oil discharge port 1431.

[0082] Combination Fig.18 As shown, in some embodiments, the filter frame 1420 includes a first frame 1421 and a second frame 1422, and the first frame 1421 and the second frame 1422 are interconnected to clamp the filter 1410 to support the filter 1410. At the same time, after the first frame 1421 and the second frame 1422 are connected and fixed to each other, an oil collecting tank 1427 is surrounded between the first frame 1421 and the second frame 1422. Through such a configuration, the assembly between the filter frame 1420 and the filter 1410 is facilitated on the basis of forming the oil collecting tank 1427. For example, the assembly process between the filter frame 1420 and the filter 1410 is as follows: first place the filter 1410 on the first frame 1421, and then control the second frame 1422 to be connected to the first frame 1421. After the second frame 1422 is connected and fixed to the first frame 1421, the filter 1410 can be fixed and the oil collecting tank 1427 can be enclosed. At this time, the filter 1410 is located in the oil collecting tank 1427.

[0083] There are many ways to connect the first frame 1421 and the second frame 1422, as long as the connection between the first frame 1421 and the second frame 1422 can be ensured to be fixed, for example, the first frame 1421 and the second frame 1422 are connected and fixed by screws. In order to improve the convenience of connection between the first frame 1421 and the second frame 1422, combined Fig.19 and Fig. 20 As shown, one of the first frame 1421 and the second frame 1422 is provided with a slot 1423, and the other of the first frame 1421 and the second frame 1422 is provided with an inserting portion 1424. When the first frame 1421 and the second frame 1422 are connected, the inserting portion 1424 is inserted into the slot 1423. On this basis, one of the first frame 1421 and the second frame 1422 is provided with a buckle 1425, and the other of the first frame 1421 and the second frame 1422 is provided with a buckle position 1426. When the first frame 1421 and the second frame 1422 are connected, the buckle 1425 is buckled with the buckle position 1426, and the assembly positioning is achieved through the cooperation of the inserting portion 1424 and the slot 1423, and further fixation is achieved through the cooperation of the buckle 1425 and the buckle position 1426.

[0084] It can be understood that one of the first frame 1421 and the second frame 1422 is provided with a slot 1423, and the other one of the first frame 1421 and the second frame 1422 is provided with a plug-in portion 1424, that is, when the first frame 1421 is provided with the slot 1423, the second frame 1422 must be provided with a corresponding plug-in portion 1424, and when the first frame 1421 is provided with a plug-in portion 1424, the second frame 1422 must be provided with a corresponding slot 1423, and when the first frame 1421 is provided with both the slot 1423 and the plug-in portion 1424, the second frame 1422 must be provided with a plug-in portion 1424 and a slot 1423, and the same is true for the settings of the buckle 1425 and the buckle position 1426.

[0085] Since the second connection part 1430 is set to the filter frame 1420, and the filter frame 1420 includes a first frame 1421 and a second frame 1422 connected to each other, in order to facilitate the communication between the oil discharge port 1431 and the oil collecting tank 1427, continue to combine Fig.19 and Fig. 20 As shown, a portion of the second connection portion 1430 is arranged on the first frame 1421 and the other portion of the second connection portion 1430 is arranged on the second frame 1422. For example, a portion of the second connection portion 1430 is integrally formed with the first frame 1421, and the other portion of the second connection portion 1430 is integrally formed with the second frame 1422. When the first frame 1421 and the second frame 1422 are connected and fixed to enclose the oil collecting tank 1427, a portion of the second connection portion 1430 cooperates with the other portion to enclose the oil drain port 1431.

[0086] Combination Fig.15 and Fig.16 As shown, in some embodiments, the second magnetic portion 1440 is disposed between the first frame 1421 and the second frame 1422. For example, the second magnetic portion 1440 is fixed to either the first frame 1421 or the second frame 1422, thereby shielding the second magnetic portion 1440. When the filter component 1400 is disassembled and assembled for cleaning, the second magnetic portion 1440 is not easily lost.

[0087] Combination Fig.14 As shown, in some embodiments, the filter component 1400 is also provided with a handle 1428. For example, the handle 1428 is arranged on the filter frame 1420. The setting of the handle 1428 provides a fulcrum for the user to grasp, so that the user can apply force to the filter component 1400 to complete the disassembly and assembly of the filter component 1400.
