[0043] This application proposes a desktop range hood, combined with Figures 1 to 7 and Fig.10 As shown, the desktop range hood includes a mounting base 2300 and an oil cup 2400. The mounting base 2300 is provided with a accommodating chamber 2320. The oil cup 2400 can be installed in the accommodating chamber 2320 or detached from the accommodating chamber 2320. One of the mounting base 2300 and the oil cup 2400 is provided with a spring buckle 2330, and the other of the mounting base 2300 and the oil cup 2400 is provided with a slot 2440. When the oil cup 2400 is installed in the accommodating chamber 2320, the spring buckle 2330 is snapped into the slot 2440. When the oil cup 2400 is detached from the accommodating chamber 2320, the spring buckle 2330 is disengaged from the slot 2440.

[0044] The oil cup 2400 can be installed in the accommodating chamber 2320 or detached from the accommodating chamber 2320, that is, the oil cup 2400 and the mounting seat 2300 are detachable. The oil cup 2400 is installed in the accommodating chamber 2320 so as to receive the oil, and the oil cup 2400 is detached from the accommodating chamber 2320 so as to facilitate the user to clean it. On this basis, by setting the spring buckle 2330 and the card slot 2440, during the installation of the oil cup 2400, the spring buckle 2330 and the card slot 2440 cooperate to achieve limiting. The cooperation between the spring buckle 2330 and the card slot 2440 is strongly perceived, which effectively prompts the user that the oil cup 2400 is installed in place, thereby improving the user's disassembly and assembly experience. In addition, through the cooperation between the spring buckle 2330 and the card slot 2440, a certain constraint is formed between the mounting seat 2300 and the oil cup 2400 to prevent the oil cup 2400 from accidentally detaching from the accommodating chamber 2320.

[0045] 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.

[0046] The tabletop hood draws oil smoke through the hood body 1000, and oil liquid is produced in the process of drawing oil smoke. The oil liquid is a complex mixture including various organic substances and water. For example, the hood body 1000 includes an air duct shell 1100, a bracket 1200, a fan 1300 and a filter component 1400. The air duct shell 1100 is provided with an air duct 1110. The air duct shell 1100 can be integrally formed or formed by connecting at least two components. 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 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 is arranged upstream of the fan 1300. The air flow first flows through the filter component 1400 and then flows through the fan 1300. The filter component 1400 can be arranged at the air inlet 1111. By arranging the filter component 1400, the filter component 1400 can filter the oil smoke to obtain oil liquid, and the oil liquid is finally guided to the oil cup 2400 to be temporarily stored and collected.

[0047] The fuselage 2000 includes a mounting seat 2300 and an oil cup 2400. The mounting seat 2300 is provided with a receiving chamber 2320. The receiving chamber 2320 is a space for receiving the oil cup 2400. The oil cup 2400 is designed to be detachably connected to the mounting seat 2300 so that it can be installed in the receiving chamber 2320 and can be detached from the receiving chamber 2320. For example, the receiving chamber 2320 is open toward the rear, and the oil cup 2400 is inserted into the receiving chamber 2320 in a direction from rear to front, and can be pulled out of the receiving chamber 2320 in a direction from front to rear. Of course, the receiving chamber 2320 can also be open toward the front, and the oil cup 2400 is inserted into the receiving chamber 2320 in a direction from front to rear, and can be pulled out of the receiving chamber 2320 in a direction from rear to front.

[0048] It is understandable that the orientation in this article is based on the air inlet 1111 of the desktop range hood facing the user. The side of the desktop range hood facing the user (i.e., the direction of the air inlet 1111) 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. When the desktop range hood needs to be used, the oil cup 2400 is installed in the accommodating chamber 2320, and 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 is detached from the accommodating chamber 2320 so that the oil can be poured out. After the oil cup 2400 is cleaned, the oil cup 2400 can be reinstalled in the accommodating chamber 2320.

[0049] In the related art, the installation of the oil cup 2400 into the accommodating cavity 2320 is entirely based on the user's feeling, which may easily lead to improper installation and the oil cup 2400 is easy to get loose. Therefore, in this embodiment, a spring buckle 2330 and a card slot 2440 are provided to cooperate with each other to solve the above problems.

[0050] One of the mounting seat 2300 and the oil cup 2400 is provided with a spring buckle 2330, and the other of the mounting seat 2300 and the oil cup 2400 is provided with a slot 2440. It should be understood that when one of them is provided with a spring buckle 2330, the other should be provided with a corresponding slot 2440. The mounting seat 2300 may be provided with a spring buckle 2330 and the oil cup 2400 may be provided with a slot 2440, or the mounting seat 2300 may be provided with a slot 2440 and the oil cup 2400 may be provided with a spring buckle 2330, or the mounting seat 2300 may be provided with both a spring buckle 2330 and a slot 2440, and the slot 2440 may be provided with a slot 2440 and a spring buckle 2330. During the process of installing the oil cup 2400 into the accommodating cavity 2320, as the oil cup 2400 moves relative to the accommodating cavity 2320, until the spring buckle 2330 cooperates with the card slot 2440, the spring buckle 2330 is snapped into the card slot 2440 to achieve mutual limitation. The mutual cooperation between the spring buckle 2330 and the card slot 2440 can give the user a stronger perception to prompt that the oil cup 2400 is installed in place. Through such a setting, the situation where the oil cup 2400 is not installed in place can be effectively avoided.

[0051] In addition, through the mutual cooperation between the spring buckle 2330 and the card slot 2440, mutual constraint is achieved between the spring buckle 2330 and the card slot 2440, that is, a certain constraint effect is generated between the mounting seat 2300 and the oil cup 2400, so that after the oil cup 2400 is installed in the accommodating chamber 2320, the oil cup 2400 is not easy to be separated from the accommodating chamber 2320 in an accidental situation, that is, when the user does not apply a detaching force to the oil cup 2400, it is difficult for the oil cup 2400 to be accidentally separated from the accommodating chamber 2320, and when the user needs to detach the oil cup 2400, the force applied by the user overcomes the constraint between the spring buckle 2330 and the card slot 2440, so that the spring buckle 2330 can be separated from the card slot 2440, and the oil cup 2400 can be smoothly detached from the accommodating chamber 2320.

[0052] When the oil cup 2400 is installed in the accommodating chamber 2320 or removed from the accommodating chamber 2320, the spring buckle 2330 can achieve a certain elastic deformation under the action of force, thereby achieving cooperation with the card slot 2440. Fig.10 and Fig.11 As shown, in some embodiments, the spring buckle 2330 is provided with a guide surface 2331 and a stop surface 2332 , and the spring buckle 2330 is provided on the mounting seat 2300 and the slot 2440 is provided on the oil cup 2400 for explanation. During the process of installing the oil cup 2400 into the accommodating cavity 2320, as the oil cup 2400 moves (approaches) relative to the mounting seat 2300, the periphery 2441 of the slot 2440 abuts against the guide surface 2331 of the spring buckle 2330. As the oil cup 2400 further moves (approaches) relative to the mounting seat 2300, the guide surface 2331 is forced to slide relative to the periphery 2441 of the slot 2440, causing the spring buckle 2330 to elastically deform. As the oil cup 2400 moves into position relative to the mounting seat 2300, the periphery 2441 of the slot 2440 and the guide surface 2331 are separated, and the spring buckle 2330 is reset and thus snapped into the slot 2440, so that the spring buckle 2330 and the slot 2440 form a mutual constraint. Similarly, during the process of the oil cup 2400 being detached from the accommodating cavity 2320, as the oil cup 2400 moves (moves away) relative to the mounting seat 2300, the groove wall 2442 of the slot 2440 contacts the stop surface 2332 of the spring button 2330. As the user applies force to control the oil cup 2400 to further move (move away) relative to the mounting seat 2300, the stop surface 2332 is forced to slide relative to the groove wall 2442 of the slot 2440, causing the spring button 2330 to elastically deform, and the oil cup 2400 can be detached relative to the mounting seat 2300 until the spring button 2330 is separated from the slot 2440 and the spring button 2330 is reset. It can be seen that the cooperation between the spring button 2330 and the slot 2440 is realized during the installation and detachment process of the oil cup 2400, and the user does not need to directly contact the spring button 2330 and the slot 2440, which is convenient and quick.

[0053] Furthermore, combined with Fig.11 As shown, in some embodiments, the inclination of the stop surface 2332 is designed to be greater than the inclination of the guide surface 2331, so that the user can install the oil cup 2400 more labor-saving than to remove the oil cup 2400, and the oil cup 2400 is less likely to detach from the accommodating cavity 2320 in an accidental situation when installed in the accommodating cavity 2320.

[0054] Specifically, the inclination here is relative to the installation direction and the removal direction of the oil cup 2400. For example, taking the oil cup 2400 moving in the horizontal direction to achieve removal and installation as an example, see Figure 4 , Figure 6 and Fig.11 In the orientation shown, the oil cup 2400 moves from the back to the front and is installed in the accommodating chamber 2320, and the oil cup 2400 moves from the front to the back and is detached from the accommodating chamber 2320. The spring buckle 2330 is suitable for elastic deformation upward and suitable for resetting downward. The inclination of the stop surface 2332 is greater than the inclination of the guide surface 2331, that is, the angle between the stop surface 2332 and the horizontal plane is greater than the angle between the guide surface 2331 and the horizontal plane. During the installation of the oil cup 2400 into the accommodating chamber 2320, the periphery 2441 of the slot 2440 generates a force on the guide surface 2331, and this force is decomposed into an upward component force F1. During the detachment of the oil cup 2400 from the accommodating chamber 2320, In the figure, the groove wall 2442 of the slot 2440 generates a force on the stop surface 2332, which decomposes the force into an upward component force F2. Assuming that the force applied by the user during the installation and removal of the oil cup 2400 is equal, since the inclination of the stop surface 2332 is larger than the inclination of the guide surface 2331, F2 is smaller than F1. In other words, when the user uses the same force to disassemble and assemble the oil cup 2400, the spring buckle 2330 is easier to elastically deform to facilitate the installation of the oil cup 2400 into the installation cavity, and is relatively difficult to elastically deform to prevent the oil cup 2400 from accidentally detaching from the accommodating cavity 2320. In other words, installing the oil cup 2400 is more labor-saving than removing the oil cup 2400.

[0055] Combination Fig.10 , Figures 12 to 15As shown, in some embodiments, the slot 2440 is provided on the oil cup 2400 and the snap 2330 is provided on the mounting seat 2300. Since the oil cup 2400 needs to be frequently disassembled and assembled for cleaning, it is inevitable to wash the oil cup 2400 when cleaning it. If the snap 2330 is provided on the oil cup 2400, and since the snap 2330 can be elastically deformed, the washing operation will generate force on the snap 2330. If the washing operation generates too much force, the snap 2330 may be broken. Therefore, in this embodiment, the snap 2330 is provided on the mounting seat 2300 and the slot 2440 is provided on the oil cup 2400. The snap 2330 will not be taken out with the oil cup 2400 when it is disassembled from the accommodating cavity 2320, so as to prevent the snap 2330 from being damaged when cleaning the oil cup 2400.

[0056] Since the spring buckle 2330 needs to undergo elastic deformation, the spring buckle 2330 is designed to be integrally formed on the mounting seat 2300 , for example, the mounting seat 2300 and the spring buckle 2330 are integrally formed by injection molding, so as to enhance the structural strength and elastic deformation performance of the spring buckle 2330 .

[0057] Furthermore, combined with Figure 7 and Fig.10 As shown, in some embodiments, the spring buckle 2330 is arranged above the slot 2440. Since the spring buckle 2330 is arranged on the mounting seat 2300, and the oil cup 2400 needs to be installed in the accommodating cavity 2320 so that the spring buckle 2330 and the slot 2440 cooperate, that is, the spring buckle 2330 is at the top of the accommodating cavity 2320. When the oil cup 2400 is detached from the accommodating cavity 2320, it is not easy for the user to observe the spring buckle 2330.

[0058] Combination Figures 4 to 6 As shown, in some embodiments, the desktop range hood also includes a body shell 2500, the mounting base 2300 is arranged inside the body shell 2500, the oil cup 2400 includes an oil cup body 2410 and a surrounding shell portion 2420, the surrounding shell portion 2420 is arranged on the oil cup body 2410, for example, the oil cup body 2410 and the surrounding shell portion 2420 are integrally injection molded, and when the oil cup 2400 is installed in the accommodating cavity 2320, specifically, the oil cup body 2410 is installed in the accommodating cavity 2320, and the surrounding shell portion 2420 is abutted against the body shell 2500, so that the surrounding shell portion 2420 constitutes part of the outer surface of the desktop range hood.

[0059] Specifically, the body shell 2500 is a part of the body 2000, forming the outer surface of the desktop range hood. The mounting seat 2300 is arranged inside the body shell 2500, and the body shell 2500 forms a shield for the mounting seat 2300. In this way, the mounting seat 2300 can be designed mainly from the functional point of view, while the body shell 2500 can be designed mainly from the appearance point of view, and the design is more flexible. The oil cup 2400 includes an oil cup body 2410 and a shell portion 2420. When the oil cup 2400 is installed in the accommodating cavity 2320, in addition to realizing the limit by the cooperation of the spring buckle 2330 and the card slot 2440, the stop can also be realized by the abutment between the shell portion 2420 and the body shell 2500, further ensuring that the oil cup 2400 is installed in place.

[0060] In some embodiments, the oil cup 2400 is exposed on the left and right sides of the desktop range hood, and is exposed on the front or rear side of the desktop range hood, that is, at least a portion of the oil cup 2400 can be seen when observing the desktop range hood from right to left, at least a portion of the oil cup 2400 can be seen when observing the desktop range hood from left to right, and at least a portion of the oil cup 2400 can be seen when observing the desktop range hood from front to back or from back to front. In this way, when disassembling and assembling the oil cup 2400, the user can hold the left and right sides of the oil cup 2400, which facilitates the user's application of force and improves the disassembly and assembly experience of the oil cup 2400.

[0061] Combination Fig.14 and Fig.15 As shown, in some embodiments, a ridge 2430 is provided on the left side of the oil cup 2400, and a ridge 2430 is also provided on the right side of the oil cup 2400. The ridge 2430 is designed to extend in the up and down directions. In this way, when the user holds the left and right sides of the oil cup 2400, the ridge 2430 is touched, which increases the friction and makes it easier to move the oil cup 2400 to complete the disassembly and assembly.

[0062] Furthermore, the accommodating chamber 2320 is open toward the rear, and the oil cup 2400 is controlled to move from the rear to the front so that it can be installed in the accommodating chamber 2320, and the oil cup 2400 is controlled to move from the front to the rear so that it can be detached from the accommodating chamber 2320, that is, the oil cup 2400 is exposed at the rear side of the desktop range hood, and at least a part of the oil cup 2400 can be seen when observing the desktop range hood from the rear to the front. In other words, it is difficult to observe the oil cup 2400 when observing the desktop range hood from the front to the rear, because the oil cup 2400 needs to be disassembled and assembled, and because an installation seam is formed between the oil cup 2400 and other parts of the body 2000, there is a sense of separation. In the present embodiment, the accommodating chamber 2320 is opened toward the rear to improve the integrity of the front side of the desktop range hood.

[0063] Combination Figure 7 , Fig.12 and Fig.13As shown, in some embodiments, the mounting base 2300 is provided with an oil guiding oil circuit 2310, and the oil guiding oil circuit 2310 is used to receive the oil generated when the desktop range hood is working. The oil guiding oil circuit 2310 is provided with an oil outlet 2312. The oil enters the oil guiding oil circuit 2310 and is discharged through the oil outlet 2312. The oil cup 2400 is provided with an oil collecting chamber 2411 (the oil collecting chamber 2411 is provided on the oil cup body 2410), and the oil discharged from the oil outlet 2312 enters the oil collecting chamber 2411. The oil guiding oil circuit 2310 is provided on the mounting base 2300, so that the mounting base 2300 can not only realize the installation of the oil cup 2400, but also guide the oil to the oil cup 2400 for temporary storage.

[0064] Specifically, combined Figure 2 , Figures 5 to 10 as well as Figures 12 to 15 As shown, the desktop hood includes a first guide member 2100 and a second guide member 2200. The hood body 1000 is provided with an oil drain port 1001. The oil generated by sucking oil smoke is discharged through the oil drain port 1001. The first guide member 2100 is used to receive the oil discharged from the oil drain port 1001. The first guide member 2100 is provided with a first outlet 2120. The first guide member 2100 discharges the oil through the first outlet 2120. The second guide member 2200 is provided with a guide slope 2230 and a second guide slope 2240. Second outlet 2220, the second guide member 2200 is used to receive the oil discharged from the first outlet 2120 through the guide slope 2230, and the second guide member 2200 discharges the oil through the second outlet 2220, the oil guiding oil circuit 2310 is used to receive the oil discharged from the second outlet 2220, the oil guiding oil circuit 2310 is provided with an oil outlet 2312, the oil guiding oil circuit 2310 discharges the oil through the oil outlet 2312, and the oil discharged from the oil outlet 2312 enters the oil collecting chamber 2411.

[0065] The first guide member 2100 is used to receive the oil discharged from the oil drain port 1001, that is, the oil discharged from the oil drain port 1001 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 drain port 1001, and may receive it directly (the oil discharged from the oil drain port 1001 directly enters the first guide member 2100) or indirectly (the oil discharged from the oil drain port 1001 indirectly enters the first guide member 2100). For example, the first guide member 2100 is arranged below the oil drain port 1001, and the oil discharged from the oil drain port 1001 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.

[0066] 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.

[0067] The oil guide path 2310 may directly receive the oil discharged from the second outlet 2220, or may indirectly receive the oil discharged from the second outlet 2220. 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 is connected to the oil collecting chamber 2411, 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 2411.

[0068] 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 2411, splashing is more likely to occur. The splashed oil adheres to the inner wall of the oil cup 2400 (the cavity wall of the oil collecting chamber 2411) and easily pollutes the installation environment of the oil cup 2400. In this embodiment, the oil is guided by providing a first guide member 2100 and a second guide member 2200 between the oil drain port 1001 and the oil cup 2400, and the second guide member 2200 is provided with a guide slope 2230. The guide slope 2230 may be a plane or a curved surface. The so-called "slant" means 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 splashing of the oil can be effectively avoided.

[0069] Combination Figure 8As shown, in some embodiments, the range hood body 1000 is connected and fixed to the first guide member 2100 by connection means, and the first guide member 2100 is provided with a first inlet 2110 for receiving the oil discharged from the oil drain port 1001. When projected in a top-down direction, the projection of the oil drain port 1001 is located within the contour of the first inlet 2110.

[0070] The range hood body 1000 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 range hood body 1000 as an integrated structure, by designing the range hood body 1000 and the first air guide 2100 as separate components, the manufacturing difficulty of the range hood body 1000 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 connected and fixed to the range hood body 1000 by screws.

[0071] In order to minimize the leakage of oil when it enters the first guide member 2100 from the oil drain port 1001, the first guide member 2100 is provided with a first inlet 2110, and the projection of the oil drain port 1001 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 1001, and the first inlet 2110 is larger than the oil drain port 1001. With such a configuration, when the oil is discharged from the oil drain port 1001, 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 1001 and the first inlet 2110. With such a configuration, the leakage of oil can be prevented without sealing between the range hood body 1000 and the first guide member 2100.

[0072] The same is true for the cooperation between the first guide member 2100 and the second guide member 2200. Figure 7 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.

[0073] Further, continue to combine Figure 7 and Figure 8 As shown, 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 .

[0074] 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. 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 1001 to the oil cup 2400. Assuming that the relative positions of the oil drain port 1001 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.

[0075] 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 follows the movement and can ensure the connection with the second air guide 2200 .

[0076] Combination Fig.13As 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 .

[0077] The same is true for the coordination between the oil outlet 2312 and the oil collecting chamber 2411. When projected in the top-down direction, the projection of the oil outlet 2312 is set within the contour of the oil collecting chamber 2411. That is, the oil collecting chamber 2411 is located below the oil outlet 2312. The oil collecting chamber 2411 is larger than the oil outlet 2312, thereby preventing oil from leaking out from between the oil outlet 2312 and the oil collecting chamber 2411.

[0078] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
