[0049] This application proposes a desktop range hood, combined with Figures 1 to 7 As shown, in some embodiments, the desktop range hood includes an air duct shell 1100, a light-transmitting cover 1510 and a light-emitting member 1520. The air duct shell 1100 is provided with an air inlet 1111, and the air inlet 1111 is open toward a first orientation. The light-transmitting cover 1510 is connected to the air duct shell 1100 so as to enclose a cavity 1600 together with the air duct shell 1100. The light-emitting member 1520 is provided in the cavity 1600. The light-emitting member 1520 is suitable for generating light, and the light is suitable for passing through the light-transmitting cover 1510 and irradiating toward the first orientation.

[0050] By providing the light-emitting component 1520, the air inlet 1111 is opened toward the first direction and the light emitted by the light-emitting component 1520 is irradiated toward the first direction, so that the user can observe the oil fume suction effect easily and provide a reference for the user to adjust the placement of the desktop range hood. It is also by providing the light-emitting component 1520 that the desktop range hood is suitable for use outdoors in a dark or dim environment. In addition, the light-emitting component 1520 is arranged in the cavity 1600 enclosed by the light-transmitting cover 1510 and the air duct shell 1100 to prevent the oil fume from contaminating the light-emitting component 1520. Compared with cleaning the light-emitting component 1520, cleaning the light-transmitting cover 1510 is easier.

[0051] 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, and 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, which is not an improvement of the present application and will not be described in detail.

[0052] The range hood body 1000 includes an air duct shell 1100, a bracket 1200, a fan 1300, a light-transmitting cover 1510 and a light-emitting component 1520. The air duct shell 1100 is provided with an air duct 1110. The air duct shell 1100 can be integrally formed or can be formed by connecting at least two parts. One end of the air duct 1110 constitutes an air inlet 1111, and the other end of the air duct 1110 constitutes 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. There are many 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 this 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 so as to be fixed. At this time, the fan 1300 is in the air duct 1110 and is located between the air inlet 1111 and the air outlet 1112. 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.

[0053] The air inlet 1111 is open toward a first orientation. For example, with the user facing the air inlet 1111 as a reference, the side of the desktop range hood facing the user 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 first orientation points to the space in front of the desktop range hood. That is to say, the desktop range hood achieves the extraction of oil fumes in the front space through the air inlet 1111.

[0054] The light-transmitting cover 1510 allows light to pass through, that is, the light-transmitting cover 1510 constitutes a transparent or translucent structure. The light-transmitting cover 1510 is connected to the air duct shell 1100, so that a cavity 1600 is formed between the light-transmitting cover 1510 and the air duct shell 1100, and the light-emitting component 1520 is arranged in the cavity 1600. The so-called light-emitting component 1520 is a component that can generate light. For example, the common light-emitting component 1520 is a lamp bead, which can generate light when the lamp bead is energized. The light generated by the light-emitting component 1520 can pass through the light-transmitting cover 1510 and irradiate toward the first direction (i.e., toward the space in front of the desktop range hood). It can be understood that since the air inlet 1111 is open toward the first direction, when the desktop range hood is working, the oil smoke is sucked in, and the oil smoke flows from the space pointed to by the first direction (the space in front of the desktop range hood) to the air inlet 1111. At this time, the light emitted by the light-emitting component 1520 passes through the light-transmitting cover 1510 and is emitted toward the space pointed to by the first direction (the space in front of the desktop range hood). When the light passes through the light-transmitting cover 1510, it can show a certain divergence. Since the oil smoke contains a large number of oil mist particles, the light will be reflected, refracted, etc. when encountering these oil mist particles. In this way, the user can observe the flow direction of the oil smoke, and the oil smoke extraction effect is intuitively presented to the user. It is understandable that since the desktop range hood is easy to carry, it is necessary to adjust the desktop range hood to a suitable position when using it. Through the above setting, since the user can directly observe the oil fume suction effect, it is convenient for the user to adjust the desktop range hood to a suitable position. By setting the light-emitting component 1520, the light-emitting component 1520 can also be used to provide lighting effects, which is suitable for use outdoors in a lightless or dim environment.

[0055] It is worth noting that oil will adhere to the desktop hood during the process of extracting oil fumes. In the present embodiment, the light-emitting component 1520 is arranged in the cavity 1600, and the cavity 1600 is enclosed by the light-transmitting cover 1510 and the air duct shell 1100. It is difficult for oil fumes to enter the cavity 1600, thereby preventing the oil fumes from contaminating the light-emitting component 1520. Even if the oil fumes contaminate the light-transmitting cover 1510, it is much more convenient for the user to clean the light-transmitting cover 1510 than to clean the light-emitting component 1520.

[0056] Combination Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the cavity 1600 surrounds the air inlet 1111, so that light can be emitted toward the first direction in the direction surrounding the air inlet 1111, thereby increasing the coverage of the light and making it easier to observe the flow of oil smoke when extracting oil smoke. Since the cavity 1600 is enclosed by the light-transmitting cover 1510 and the air duct shell 1100, the light-transmitting cover 1510 also needs to surround the air inlet 1111, for example Figure 2In the structure shown, the light-transmitting cover 1510 is in a circular ring shape and is installed at the air inlet end of the air duct shell 1100. When the light-emitting element 1520 emits light, a light-emitting ring can be formed on the desktop range hood to increase the irradiation range of the oil smoke, thereby making it more convenient for users to observe the flow of the oil smoke.

[0057] Further, under the premise that the light-transmitting cover 1510 is also designed to surround the air inlet 1111, Figure 1 , Figure 2 , Figure 6 and Fig.11 As shown, in some embodiments, the light-transmitting cover 1510 is designed to be tapered along the flow direction of the oil smoke, so that it can guide the oil smoke entering the air inlet 1111, reduce the turbulence at the air inlet 1111, and help improve the oil smoke suction effect and reduce noise.

[0058] Combination Figure 1 As shown, in some embodiments, the light emitting member 1520 is in a strip shape, and the light emitting member 1520 is arranged along the extension direction of the cavity 1600 .

[0059] Specifically, the strip-shaped light-emitting element 1520 constitutes a light strip, which may include a plurality of lamp beads. The light-emitting element 1520 is arranged along the extension direction of the cavity 1600, that is, surrounding the air outlet 1112. Therefore, in the direction surrounding the air outlet 1112, there are corresponding light sources to generate light passing through the light-transmitting cover 1510, further improving the intensity of the light, which is more conducive to improving the lighting effect.

[0060] Combination Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, in some embodiments, the air duct housing 1100 is provided with a groove 1140 , the light-transmitting cover 1510 covers the groove 1140 to enclose a cavity 1600 , and the light-emitting element 1520 is connected to the groove wall of the groove 1140 .

[0061] Specifically, refer to Fig.10 In the orientation shown, the groove 1140 of the air duct housing 1100 is open to the front. During assembly, the light emitting member 1520 can be first connected to the groove wall of the groove 1140 to fix the light emitting member 1520, and then the light-transmitting cover 1510 is connected to the air duct housing 1100 and covers the groove 1140, so that a cavity 1600 (the groove 1140 is at least a part of the cavity 1600) is enclosed between the light-transmitting cover 1510 and the air duct housing 1100 to protect the light emitting member 1520. It can be understood that the light-transmitting cover 1510 is a separate component and is installed last. The light emitting member 1520 is first connected to the groove wall of the groove 1140 and fixed, which is convenient for wiring and power supply.

[0062] Furthermore, combined with Fig.10 As shown, in some embodiments, the groove wall of the groove 1140 includes a groove bottom wall 1141 and a groove side wall 1142, and the groove side walls 1142 are respectively arranged on opposite sides of the groove bottom wall 1141, so that an opening is formed between the groove side walls 1142 on the opposite sides, such as Fig.10 In the orientation shown, the groove 1140 has an opening and is open to the front. The light emitting member 1520 is installed in the groove side wall 1142 on one side. Fig.10 In the groove side wall 1142 on the lower side of the orientation shown, the light emitting component 1520 emits light toward the groove side wall 1142 on the other side (the groove side wall 1142 on the upper side), and the light emitted by the light emitting component 1520 is reflected by the groove side wall 1142 on the other side (the groove side wall 1142 on the upper side) and then passes through the light-transmitting cover 1510 and irradiates toward the first orientation. Since the light emitted by the light emitting component 1520 is reflected by the groove side wall 1142 on the other side (the groove side wall 1142 on the upper side), the light is further diverged after being reflected, thereby improving the light output uniformity of the light-transmitting cover 1510.

[0063] Combination Figures 1 to 7 As shown, in some embodiments, the air duct shell 1100 includes a first shell 1120 and a mounting frame 1130 , the mounting frame 1130 is connected to the inner wall of the first shell 1120 to surround the air inlet 1111 , and the light-transmitting cover 1510 is connected to the mounting frame 1130 to enclose a cavity 1600 with the mounting frame 1130 .

[0064] Specifically, the first housing 1120 constitutes most of the air duct housing 1100, the mounting frame 1130 is connected to the inner wall of the air inlet end of the first housing 1120, the light-transmitting cover 1510 is connected to the mounting frame 1130, and the mounting frame 1130 and the first housing 1120 are independent components connected and fixed by connecting means. By designing an independent mounting frame 1130, it is convenient to set a connecting structure on the mounting frame 1130, especially when multiple connecting structures are set on the mounting frame 1130. Compared with the integral molding of the mounting frame 1130 and the first housing 1120, the manufacturing difficulty can be effectively reduced in this embodiment. In addition, if other components need to be installed inside the first housing 1120, these components can be installed first and then the mounting frame 1130 is connected to the first housing 1120 to avoid interference.

[0065] There are many ways to connect the installation frame 1130 and the first shell 1120, such as snap-fit ​​connection between the installation frame 1130 and the first shell 1120, which is convenient and quick. Since the snap-fit ​​connection does not require direct operation by the user, the snap-fit ​​connection can be achieved by controlling the installation frame 1130 to align with the corresponding position of the first shell 1120 until it moves into place. And since the installation frame 1130 is connected to the inner wall of the first shell 1120, when the installation frame 1130 and the first shell 1120 are snap-fitted, the connection structure between the installation frame 1130 and the first shell 1120 can be hidden to avoid exposure. Similarly, the light-transmitting cover 1510 can also be designed to be snap-fitted with the installation frame 1130.

[0066] Continue to combine Figures 1 to 8 as well as Figure 12 to Figure 13 As shown, in some embodiments, the desktop hood further includes a filter component 1400, which is used to filter the oil smoke. The filter component 1400 is located on the path of the oil smoke flow, for example, the filter component 1400 is arranged at the air inlet 1111, and the oil smoke first flows through the filter component 1400 when entering from the air inlet 1111 and is filtered by the filter component 1400, and then flows through the fan 1300 and is discharged. In this embodiment, the filter component 1400 is connected to the installation frame 1130, that is, the light-transmitting cover 1510 and the filter component 1400 both need to be connected and fixed to the installation frame 1130. Since the installation frame 1130 is an independent component relative to the first housing 1120, it is convenient to design the connection structure for connecting with the light-transmitting cover 1510 and the connection structure for connecting with the filter component 1400 for the installation frame 1130.

[0067] The installation frame 1130 is provided with a first magnetic attraction portion 1132 and a first connection portion 1131, and the filter component 1400 is provided with a second magnetic attraction portion 1440 and a second connection portion 1430. The first connection portion 1131 and the second connection portion 1430 are used for plug-in connection, and the first magnetic attraction portion 1132 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 installation frame 1130. The plug-in connection between the first connection portion 1131 and the second connection portion 1430 can realize the rapid positioning of the filter component 1400, and then the magnetic connection between the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440 can realize further fixation. The structure is simple, and the convenience of disassembly and assembly of the filter component 1400 is effectively improved.

[0068] After a period of use, the filter component 1400 will accumulate dirt and even become clogged, so it is necessary to disassemble the filter component 1400 for cleaning. In the related art, the filter component 1400 is fixed by screwing, that is, when installing the filter component 1400, it is necessary to screw it, and when removing the filter component 1400, it is necessary to loosen the screw. 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 1131 is matched with the second connecting part 1430, and the first magnetic part 1132 is matched with the second magnetic part 1440 to solve the problem.

[0069] When the filter component 1400 is installed on the installation frame 1130, the second connection part 1430 is controlled to cooperate with the first connection part 1131. The cooperation between the second connection part 1430 and the first connection part 1131 is realized in the form of a plug-in connection. The second connection part 1430 can be inserted into the first connection part 1131, or the first connection part 1131 can be inserted into the second connection part 1430. As long as one of the first connection part 1131 and the second connection part 1430 is inserted into the other of the first connection part 1131 and the second connection part 1430, quick positioning can be achieved, which is convenient and quick. For example, the first connection part 1131 is a socket, and the second connection part 1430 is inserted into the socket to realize a quick plug-in connection.

[0070] Based on the plug-in connection between the first connecting portion 1131 and the second connecting portion 1430, the second magnetic attraction portion 1440 is controlled to cooperate with the first magnetic attraction portion 1132. The cooperation between the second magnetic attraction portion 1440 and the first magnetic attraction portion 1132 is realized in the form of magnetic attraction connection. The first magnetic attraction portion 1132 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 1132, or the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440 may generate a magnetic field to attract the first magnetic attraction portion 1132. They generate magnetic fields respectively and attract each other. On the basis of the plug-in connection between the first connecting part 1131 and the second connecting part 1430, the magnetic connection between the first magnetic part 1132 and the second magnetic part 1440 can be achieved by controlling the first magnetic part 1132 and the second magnetic part 1440 to be close to each other. It is convenient and quick. For example, the first magnetic part 1132 is a magnet and the second magnetic part 1440 is also a magnet. In this way, the first magnetic part 1132 and the second magnetic part 1440 generate magnetic fields respectively to increase the attraction force of the magnetic connection.

[0071] 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 installation frame 1130, 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 1132 and the second magnetic attraction part 1440, so that the first magnetic attraction part 1132 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 1131. In this way, the removal of the filter component 1400 is completed, and the filter component 1400 is convenient for cleaning.

[0072] Combination Figures 6 to 8 as well as Figure 12 to Figure 14 As 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 installation frame 1130, 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.

[0073] See also Figure 1 The positions of the second connection part 1430 and the second magnetic attraction part 1440 are set as follows: the second connection part 1430 can be set on the left side of the filter component 1400 and the second magnetic attraction part 1440 can be set on the right side of the filter component 1400, the second connection part 1430 can be set on the right side of the filter component 1400 and the second magnetic attraction part 1440 can be set on the left side of the filter component 1400, and the second connection part 1430 can be set on the upper side of the filter component 1400 and the second magnetic attraction part 1440 can be set on the lower side of the filter component 1400. It can be understood that no matter where the second connection part 1430 and the second magnetic attraction part 1440 are set, the first connection part 1131 and the first magnetic attraction part 1132 need to be set accordingly.

[0074] In some embodiments, the second connection portion 1430 is disposed on the lower side of the filter component 1400 and the second magnetic attraction portion 1440 is disposed on the upper side of the filter component 1400. When the filter component 1400 is installed on the installation frame 1130, the second connection portion 1430 is first controlled to be plugged and connected with the first connection portion 1131. 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 1131, thereby facilitating the control. The second connection part 1430 cooperates with the first connection part 1131. After the second connection part 1430 is plugged into the first connection part 1131, the filter component 1400 can be stopped on the installation frame 1130 under the force applied by the user and gravity, and the installation frame 1130 is not easy to loosen. The upper side of the filter component 1400 continues to be controlled to rotate toward the installation frame 1130, so that the second magnetic part 1440 gradually approaches the first magnetic part 1132 until it is attracted, thereby further improving the convenience of disassembly and assembly.

[0075] Combination Figures 6 to 10 As shown, in some embodiments, the installation frame 1130 is provided with a stop portion 1133, and the stop portion 1133 is arranged downstream of the filter component 1400. The stop portion 1133 is used to abut against the filter component 1400 during the installation process, thereby preventing the filter component 1400 from continuing to move toward the inside of the air duct 1110, thereby strengthening the positioning effect of the installation of the filter component 1400.

[0076] Specifically, it can be seen from the above that the first connection part 1131 and the second connection part 1430 can play a positioning role only when they are matched. By setting the stopper 1133, during the installation of the filter component 1400, the stopper 1133 can abut against the filter component 1400, thereby blocking the filter component 1400 from continuing to move along the air duct 1110, making it easier to align the first connection part 1131 and the second connection part 1430, thereby playing a role in strengthening positioning. It is precisely because the stopper 1133 can abut against the filter component 1400 that the first magnetic attraction part 1132 can be set on the stopper 1133, and the filter component 1400 and the stopper 1133 can be adsorbed together when they are abutted.

[0077] Combination Figure 8 As shown, in some embodiments, the first connection portion 1131 is a socket and the second connection portion 1430 is inserted into the socket, the second connection portion 1430 is provided with an oil drain port 1431 , and the filter component 1400 is used to drain oil through the oil drain port 1431 .

[0078] Specifically, when the tabletop hood is sucking out oil smoke, the oil smoke is filtered by the filter component 1400, and oil liquid is generated on the filter component 1400. The oil liquid is a complex mixture, including various organic substances and water. The oil liquid 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 1131 (socket), the oil discharge port 1431 is set in the second connection part 1430, and the oil liquid is discharged through the oil discharge port 1431. It can be understood that the tabletop hood includes an oil cup 2400, which is configured to be detachable, and the oil liquid discharged from the oil discharge port 1431 eventually enters the oil cup 2400 for temporary storage. The oil cup 2400 is designed to be detachable. When the desktop range hood is in use, the oil produced 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 the oil cup 2400 is cleaned, the oil cup 2400 can be installed back into the desktop range hood.

[0079] Combination Figures 12 to 15 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.

[0080] 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.

[0081] Combination Figures 12 to 16As 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.

[0082] 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.17 and Fig.18 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.

[0083] 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.

[0084] 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.17 and Fig.18 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.

[0085] Combination Fig.13 and Fig.14 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.

[0086] Combination Fig.12 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.
