Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

[0058] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. 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.

[0059] This application proposes a desktop range hood, combined with Figures 1 to 5 As shown, in some embodiments, the desktop range hood includes a range hood body 1000 and a body 2000, the range hood body 1000 is rotatably connected to the body 2000 so as to be able to swing relative to the body 2000, and two swinging gears are formed between the range hood body 1000 and the body 2000.

[0060] The range hood body 1000 can be swung relative to the body 2000. The suction direction can be adjusted by controlling the swing of the range hood body 1000 relative to the body 2000, thereby improving the convenience of use. At least two swing gears are formed between the range hood body 1000 and the body 2000. When the range hood body 1000 is swung to a corresponding swing gear, the stability of the range hood body 1000 can be enhanced, and the range hood body 1000 is not easy to rotate at will relative to the body 2000.

[0061] Specifically, the desktop range hood includes a range hood body 1000 and a body 2000. The range hood body 1000 is mounted 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, and the range hood body 1000 is used to extract oil smoke.

[0062] The range 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 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 and fixed with the air duct shell 1100. There are many ways to connect the bracket 1200 and the air duct shell 1100, such as welding, screw connection, 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 of regular shape or irregular shape. In this embodiment, the bracket 1200 is a sheet metal part. The so-called sheet metal part is the bracket 1200 processed by sheet metal technology. The fan 1300 is connected to the bracket 1200 and fixed in the air duct 1110. At this time, the fan 1300 is between the air inlet 1111 and the air outlet 1112. The fan 1300 drives the oil smoke to enter the air duct 1110 from the air inlet 1111 and discharge the oil smoke from the air outlet 1112. The filter component 1400 is installed on the air duct housing 1100 and is located in the air duct 1110. The filter component 1400 is located upstream of the fan 1300, for example, at the air inlet 1111. The oil smoke first flows through the filter component 1400 and then flows through the fan 1300. By setting the filter component 1400, the filter component 1400 can filter the oil smoke to obtain oil liquid. The body 2000 supports the range hood body 1000 . The desktop range hood includes an oil cup 2400 . The oil cup 2400 is installed in the body 2000 . The oil discharged from the range hood body 1000 eventually enters the oil cup 2400 for temporary storage.

[0063] In the related art, the range hood body 1000 is installed on the body 2000 and cannot move relative to the body 2000. In this way, when the desktop range hood is placed on the desktop, the range hood body 1000 can only suck oil fumes in a specific direction. If the suction direction needs to be adjusted, it is often necessary to adjust the position of the entire desktop range hood. This solution brings inconvenience to operation.

[0064] To this end, in the present embodiment, the range hood body 1000 is rotatably connected to the body 2000, so that the range hood body 1000 can swing relative to the body 2000. When the desktop range hood is placed on the desktop, the user can control the range hood body 1000 to swing relative to the body 2000 (that is, the range hood body 1000 rotates relative to the body 2000) to adjust the direction of the range hood body 1000. For example, the range hood body 1000 swings relative to the body 2000 to the position with the most oil smoke. In this way, the oil smoke at the corresponding position can be sucked out. Compared with adjusting the entire desktop range hood, it is more convenient to swing the range hood body 1000.

[0065] There are many ways to swing the range hood body 1000 relative to the body 2000. 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 of the desktop range hood facing away from the user is the back, the desktop range hood corresponding to the user's left hand is the left, the desktop range hood corresponding to the user's right hand is the right, the desktop range hood close to the desktop is the bottom, and the desktop range hood away from the desktop is the top. The range hood body 1000 can be swung in the up-down direction relative to the body 2000 (so that the range hood body 1000 can absorb oil smoke at different heights), or it can be swung in the left-right direction relative to the body 2000 (so that the range hood body 1000 can absorb oil smoke in different ranges in the horizontal direction).

[0066] It can be understood that since the swinging of the range hood body 1000 is achieved by rotation, in order to prevent the range hood body 1000 from arbitrarily / accidentally rotating relative to the body 2000 (that is, when the range hood body 1000 is swung to the corresponding position, in order to prevent the range hood body 1000 from arbitrarily / accidentally leaving the position), at least two swing positions are formed between the range hood body 1000 and the body 2000, and the range hood body 1000 can be rotated to the corresponding swing positions, that is, the range hood body 1000 can be rotated to at least two angles relative to the body 2000, and each swing position corresponds to one angle. When the range hood body 1000 swings to a certain swing position, a certain restraining effect is formed between the range hood body 1000 and the fuselage 2000, which can effectively prevent the range hood body 1000 from deviating from the current swing position relative to the fuselage 2000 without the application of human force, thereby preventing the range hood body 1000 from rotating randomly / accidentally. By such a setting, the stability of the range hood body 1000 relative to the fuselage 2000 can be enhanced.

[0067] Combination Figure 5 , Figure 7 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, in some embodiments, one of the range hood body 1000 and the fuselage 2000 is provided with a first connection part 1600, and the other of the range hood body 1000 and the fuselage 2000 is provided with a second connection part 2500, the second connection part 2500 includes an axial hole 2510, and the first connection part 1600 includes a rotating shaft 1610, and the rotating shaft 1610 and the axial hole 2510 are rotatably connected, thereby realizing the rotatable connection between the range hood body 1000 and the fuselage 2000.

[0068] Specifically, one of the range hood body 1000 and the body 2000 is provided with a first connection part 1600, and the other of the range hood body 1000 and the body 2000 is provided with a second connection part 2500. It should be understood that when one of them is provided with a first connection part 1600, the other should be provided with a corresponding second connection part 2500. For example, when the range hood body 1000 is provided with a first connection part 1600, the corresponding body 2000 should be provided with a second connection part 2500, and when the range hood body 1000 is provided with a second connection part 2500, the corresponding body 2000 should be provided with a first connection part 1600. The cooperation between the shaft hole 2510 and the rotating shaft 1610 can realize the rotatable connection between the first connection part 1600 and the second connection part 2500, and the rotatable connection between the first connection part 1600 and the second connection part 2500 can realize the rotatable connection between the range hood body 1000 and the body 2000.

[0069] Furthermore, combined with Fig. 9 and Fig.10 As shown, in some embodiments, the shaft hole 2510 includes two (meaning that the number of the shaft holes 2510 is at least two), the rotating shaft 1610 includes two (meaning that the number of the rotating shaft 1610 is at least two), the two shaft holes 2510 correspond one to one with the two rotating shafts 1610, the two shaft holes 2510 are arranged opposite to each other and alternately, and the first connecting part 1600 is arranged between the two shaft holes 2510. Through such an arrangement, the stability of the rotatable connection between the range hood body 1000 and the fuselage 2000 can be enhanced.

[0070] Specifically, see Fig. 9 and Fig.10In the orientation shown, the two shaft holes 2510 are arranged opposite to each other and alternately along the left-right direction, and the first connecting part 1600 is located between the shaft hole 2510 on the left and the shaft hole 2510 on the right, wherein one of the rotating shafts 1610 is protruded on the left side of the first connecting part 1600 and inserted into the shaft hole 2510 on the left, and the other rotating shaft 1610 is protruded on the right side of the first connecting part 1600 and inserted into the shaft hole 2510 on the right, the rotating shaft 1610 on the left and the shaft hole 2510 on the left are rotatably connected, and the rotating shaft 1610 on the right and the shaft hole 2510 on the right are rotatably connected. By such an arrangement, the rotatable connection between the first connecting part 1600 and the second connecting part 2500 can be achieved, and the stability of the rotatable connection between the first connecting part 1600 and the second connecting part 2500 can be enhanced, thereby enhancing the stability of the rotatable connection between the range hood body 1000 and the fuselage 2000.

[0071] Under the premise of providing two shaft holes 2510 and two rotating shafts 1610, in order to facilitate the assembly of the first connecting part 1600 and the second connecting part 2500, Fig. 9 As described, in some embodiments, the first connecting portion 1600 includes a rotating shaft shell 1620 and a first elastic member 1630 (the first elastic member 1630 is such as a spring), the rotating shaft 1610 can be slidably disposed on the rotating shaft shell 1620, and the first elastic member 1630 is disposed between the rotating shaft shell 1620 and the rotating shaft 1610, and the first elastic member 1630 is used to generate a force on the rotating shaft 1610, and the force is directed toward the shaft hole 2510.

[0072] Specifically, the shaft housing 1620 includes two cavities 1621 (cavity 1621 is a space for the shaft 1610 to slide) and two first elastic members 1630. The two cavities 1621 are arranged in the left and right directions and are separated from each other. One of the first elastic members 1630 is arranged in the cavity 1621 on the left side, and one of the shafts 1610 and the cavity 1621 on the left side can be slidably arranged. The other first elastic member 1630 is arranged in the cavity 1621 on the right side, and the other shaft 1610 and the cavity 1621 on the right side can be slidably arranged. One end of the first elastic member 1630 on the left side is inserted into the cavity 1621 on the left side. The first elastic member 1630 on the right side has one end inserted into the rotating shaft 1610 on the right side, and the other end abuts against the bottom of the cavity 1621 on the left side. The first elastic member 1630 on the left side generates a force toward the shaft hole 2510 on the left side on the rotating shaft 1610, so that the rotating shaft 1610 on the left side passes through the rotating shaft shell 1620 and is exposed. The first elastic member 1630 on the right side generates a force toward the shaft hole 2510 on the right side on the rotating shaft 1610, so that the rotating shaft 1610 on the right side passes through the rotating shaft shell 1620 and is exposed. When the first connecting part 1600 is assembled to the second connecting part 2500, the rotating shaft 1610 is controlled to retract (retract toward the cavity 1621). When the rotating shaft 1610 retracts, it slides relative to the cavity 1621, thereby driving the first elastic member 1630 to deform. The first elastic member 1630 accumulates elastic potential energy. When the first connecting part 1600 and the second connecting part 2500 are assembled in place, the first elastic member 1630 releases the elastic potential energy, pushing the rotating shaft 1610 to slide relative to the cavity 1621 (opposite to the aforementioned sliding direction). The rotating shaft 1610 passes through the rotating shaft shell 1620 to be exposed and is inserted into the shaft hole 2510, thereby realizing the rotatable connection between the rotating shaft 1610 and the shaft hole 2510.

[0073] Furthermore, combined with Figures 11 to 13 As shown, in some embodiments, the rotating shaft 1610 is provided with a guide slope 1611. When the first connecting part 1600 and the second connecting part 2500 are assembled, the guide slope 1611 is used to abut against the periphery of the shaft hole 2510, so that the rotating shaft 1610 retracts first and then extends, thereby being inserted into the shaft hole 2510.

[0074] Specifically, when the first connection part 1600 and the second connection part 2500 are assembled, the first connection part 1600 can be controlled to move toward the second connection part 2500, so that the guide bevel 1611 encounters the abutment of the periphery of the shaft hole 2510. As the first connection part 1600 continues to move toward the second connection part 2500, the periphery of the shaft hole 2510 generates a force on the guide bevel 1611, and generates a component force on the rotating shaft 1610 along the axial direction of the rotating shaft 1610, thereby causing the rotating shaft 1610 to retract (retract toward the cavity 1621), and the first elastic member 1630 accumulates elastic potential energy until the first connection part 1600 moves into place. At this time, the first elastic member 1630 releases the elastic potential energy to drive the rotating shaft 1610 to be inserted into the shaft hole 2510. In this process, the user does not need to directly contact the rotating shaft 1610, and the assembly between the first connection part 1600 and the second connection part 2500 can be achieved more conveniently and quickly.

[0075] Combination Figure 5 , Figure 8 as well as Figures 10 to 12 As shown, in some embodiments, one of the range hood body 1000 and the fuselage 2000 is provided with a first limit member 1700, and the other of the range hood body 1000 and the fuselage 2000 is provided with a second limit member 2600, and the second limit member 2600 is provided with at least two limit grooves 2610. When the range hood body 1000 swings, the first limit member 1700 can be inserted into any one of the limit grooves 2610, so that at least two swing positions are formed between the range hood body 1000 and the fuselage 2000.

[0076] Specifically, one of the range hood body 1000 and the fuselage 2000 is provided with a first position-limiting member 1700, and the other of the range hood body 1000 and the fuselage 2000 is provided with a second position-limiting member 2600. It should be understood here that when one of them is provided with the first position-limiting member 1700, the other one should be provided with the corresponding second position-limiting member 2600. For example, when the range hood body 1000 is provided with the first position-limiting member 1700, the corresponding fuselage 2000 should be provided with the second position-limiting member 2600, and when the range hood body 1000 is provided with the second position-limiting member 2600, the corresponding fuselage 2000 should be provided with the first position-limiting member 1700. The first position-limiting member 1700 can be inserted into one of the position-limiting grooves 2610 to form a swing gear. Since the second position-limiting member 2600 is provided with at least position-limiting grooves 2610, at least two swing gears are formed, for example Figure 1 The structure shown has two limit grooves 2610, thereby forming two swing gears, and the range hood body 1000 can be adjusted up and down.

[0077] Combination Figure 8As shown, in some embodiments, the first limiting member 1700 includes a shell 1710, a pin 1720 and a second elastic member 1730 (the second elastic member 1730 is such as a spring). The pin 1720 can be slidably disposed on the shell 1710, and the second elastic member 1730 is disposed between the shell 1710 and the pin 1720. The second elastic member 1730 is used to generate a force on the pin 1720. When the range hood body 1000 swings, the pin 1720 can be disengaged from the current limiting groove 2610, and when the range hood body 1000 swings into place, the pin 1720 can be snapped into the corresponding limiting groove 2610 under the action of the second elastic member 1730. Through such coordination, the switching of different swing gears is convenient.

[0078] For example, Figure 5 and Figure 8 The structure shown is for reference. At this time, the pin 1720 is inserted into the limiting groove 2610 located below. When the user controls the range hood body 1000 to swing downward, the pin 1720 is disengaged from the limiting groove 2610 below (the current limiting groove 2610) under the action of force, and the pin 1720 retracts toward the shell 1710. The second elastic member 1730 is deformed and accumulates elastic potential energy. As the range hood body 1000 swings into place, the second elastic member 1730 releases the elastic potential energy, driving the pin 1720 to stretch and be inserted into the limiting groove 2610 above (corresponding to the limiting groove 2610).

[0079] Furthermore, combined with Figure 8 As shown, in some embodiments, the pin 1720 has an arc-shaped end face, and the limiting groove 2610 has an arc-shaped groove wall. When the pin 1720 is inserted into the limiting groove 2610, the arc-shaped end face abuts against the arc-shaped groove wall. When the user controls the range hood body 1000 to swing, the force generated between the arc-shaped end face and the arc-shaped groove wall makes it easier for the pin 1720 to retract.

[0080] Combination Figure 5 , Figure 8 , Fig.11 and Fig.12 As shown, in some embodiments, the range hood body 1000 can be swung along the up and down directions relative to the body 2000, and the desktop range hood also includes a casing 1800, which is arranged on the range hood body 1000 and is designed to be in a state of being inserted into the body 2000. Through the setting of the casing 1800, no matter which swing position the range hood body 1000 is in, the casing 1800 can block the space between the range hood body 1000 and the body 2000, thereby preventing the user from observing the internal structure of the desktop range hood through the space between the range hood body 1000 and the body 2000.

[0081] On the premise of setting the enclosure 1800, one of the first stopper 1700 and the second stopper 2600 can be set on the enclosure 1800, and one of the first connecting portion 1600 and the second connecting portion 2500 can also be set on the enclosure 1800. Fig.11 In the embodiment, the first connection portion 1600 and the first limit member 1700 are both arranged on the casing 1800 , and the first connection portion 1600 is located on the front side of the casing 1800 , and the first limit member 1700 is located on the rear side of the casing 1800 .

[0082] Combination Figures 1 to 4 As shown, in some embodiments, the desktop range hood also includes a base 3000, and the body 2000 is fixed on the base 3000, that is, when the desktop range hood is placed on the desktop, the base 3000 is in contact with the desktop, and the base 3000 supports the body 2000 and the range hood body 1000. In this embodiment, the projection is made in a top-down direction, and the projection of the base 3000 is designed to be larger than the projection of the body 2000, thereby improving the placement stability of the desktop range hood. Through such a setting, the base 3000 can be made thin enough to support the body 2000 and the range hood body 1000, and because the base 3000 is closer to the desktop, the space occupied by the user can be reduced as much as possible.

[0083] In particular, the projection of the fuselage 2000 is designed to be within the range of the outline of the projection of the base 3000, and the outline of the projection of the fuselage 2000 and the outline of the projection of the base 3000 are designed to be alternately arranged, so that in the direction around the base 3000 (circumferential direction), the supporting stability of the fuselage 2000 and the range hood body 1000 is further improved.

[0084] Combination Figure 5 , Figure 7 and Fig.14As shown, the range hood body 1000 is provided with an oil drain port 1150, and the range hood body 1000 is suitable for discharging oil through the oil drain port 1150. The desktop range hood further includes a first guide member 2100, a second guide member 2200 and an oil cup 2400. The first guide member 2100 is fixed to the range hood body 1000, and the first guide member 2100 is used to receive the oil discharged from the oil drain port 1150. The first guide member 2100 is provided with a first outlet 2120, and the first guide member 2100 discharges oil through the first outlet 2120. To discharge the oil, the second guide member 2200 is provided with a second inlet 2210 and a second outlet 2220, the first outlet 2120 is designed to be inserted into the second inlet 2210, and the first guide member 2100 and the second guide member 2200 are designed to be arranged alternately, the second guide member 2200 receives the oil discharged from the first outlet 2120 and discharges it through the second outlet 2220, the oil cup 2400 is used to receive the oil discharged from the second outlet 2220, and the oil cup 2400 is designed to be detachable.

[0085] The first guide member 2100 is used to receive the oil discharged from the oil drain port 1150, that is, the oil discharged from the oil drain port 1150 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 1150, and may receive the oil directly (the oil discharged from the oil drain port 1150 directly enters the first guide member 2100) or indirectly (the oil discharged from the oil drain port 1150 indirectly enters the first guide member 2100). For example, the first guide member 2100 is arranged below the oil drain port 1150, and the oil discharged from the oil drain port 1150 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.

[0086] The second guide member 2200 is used to receive the oil discharged from the first outlet 2120, that is, the oil discharged from the first outlet 2120 enters the second guide member 2200, is guided under the action of the second guide member, and then is discharged through the second outlet 2220 of the second guide member 2200. For example, the second guide member 2200 is arranged below the first outlet 2120, and the oil discharged from the first outlet 2120 enters the second guide member 2200 under the action of gravity, and the second guide member 2200 guides the oil entering it, and the oil continues to flow under the action of gravity and then is discharged from the second guide member 2200 through the second outlet 2220.

[0087] Since the first air guide 2100 is fixed to the range hood body 1000, the first air guide 2100 will change position with the swing of the range hood body 1000. In order to ensure the communication between the first air guide 2100 and the second air guide 2200, in this embodiment, the first outlet 2120 is designed to be inserted into the second inlet 2210, and the first air guide 2100 is designed to be arranged alternately with the second air guide 2200. That is, the second inlet 2210 is much larger than the first outlet 2120, and the end of the first air guide 2100 where the first outlet 2120 is located is inserted into the end of the second inlet 2210 of the second air guide 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 range hood body 1000 swings relative to the body 2000, the first air guide 2100 moves accordingly and can ensure the communication with the second air guide 2200.

[0088] The oil cup 2400 is used to receive the oil discharged from the second outlet 2220, that is, the oil discharged from the second outlet 2220 enters the oil cup 2400 for temporary storage, and the oil discharged from the second outlet 2220 can enter the oil cup 2400 directly or indirectly. The oil cup 2400 is designed to be detachable, that is, the oil cup 2400 can be installed at a predetermined position or can be disassembled, so that the user can remove the oil cup 2400 and pour out the oil and clean the oil cup 2400, and then reinstall the cleaned oil cup 2400 to the predetermined position.

[0089] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the range hood body 1000 includes an air duct shell 1100, a light-transmitting cover 1510 and a light-emitting component 1520. The air duct shell 1100 is provided with an air inlet 1111, and the air inlet 1111 is open toward the first orientation. The light-transmitting cover 1510 is connected to the air duct shell 1100 so as to enclose a cavity 1530 together with the air duct shell 1100. The light-emitting component 1520 is provided in the cavity 1530. The light-emitting component 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.

[0090] By setting 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 it is convenient for the user to observe the oil fume suction effect, and it can provide a reference for the user to adjust the placement position of the desktop range hood / the swing gear of the range hood body 1000. It is also by setting the light-emitting component 1520 that the desktop range hood is suitable for use in outdoor lightless or dim environments. In addition, the light-emitting component 1520 is arranged in the cavity 1530 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.

[0091] Specifically, 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.

[0092] The light-transmitting cover 1510 can allow 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 1530 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 1530. 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 element 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, 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 element 1520 passes through the light-transmitting cover 1510 and irradiates 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 present a certain Since the oil smoke contains a large number of oil mist particles, the light will be reflected and refracted when encountering these oil mist particles, so the user can observe the flow direction of the oil smoke, and the oil smoke extraction effect is intuitively presented to the user. Through such a setting, since the user can directly observe the oil smoke extraction effect, it is convenient for the user to adjust the desktop range hood to a suitable position or adjust the range hood body 1000 to a suitable swing gear. It is also through the setting of the light-emitting part 1520 that the light-emitting part 1520 can also be used to provide lighting effects, which is suitable for use outdoors in a dark or dim environment.

[0093] 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 1530, and the cavity 1530 is enclosed by the light-transmitting cover 1510 and the air duct shell 1100. It is difficult for oil fumes to enter the cavity 1530, 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.

[0094] Combination Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the cavity 1530 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 1530 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 2 In 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.

[0095] Further, under the premise that the light-transmitting cover 1510 is also designed to surround the air inlet 1111, Figure 1 , Figure 2 and Fig.16 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.

[0096] Combination Figure 1 and Figure 2 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 1530 .

[0097] 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 1530, 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.

[0098] Combination Figure 6 and Fig.15As 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 1530 , and the light-emitting element 1520 is connected to the groove wall of the groove 1140 .

[0099] Specifically, refer to Fig.15 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 1530 (the groove 1140 is at least a part of the cavity 1530) 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.

[0100] Furthermore, combined with Fig.15 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.15 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.15 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, which is beneficial to improving the light output uniformity of the light-transmitting cover 1510.

[0101] 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 1530 with the mounting frame 1130 .

[0102] 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.

[0103] 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.

[0104] Continue to combine Figures 1 to 7 As shown, in some embodiments, the filter component 1400 is connected to the mounting frame 1130, that is, both the light-transmitting cover 1510 and the filter component 1400 need to be connected and fixed to the mounting frame 1130. Since the mounting frame 1130 is an independent component relative to the first shell 1120, the mounting frame 1130 is conveniently designed with a connection structure for connecting to the light-transmitting cover 1510 and a connection structure for connecting to the filter component 1400.

[0105] Combination Figure 5 , Figure 7 and Fig.17 As shown, in some embodiments, the filter component 1400 is provided with an oil drain port 1428, and the mounting frame 1130 is provided with an oil drain port 1150. The oil drain port 1428 is inserted into the oil drain port 1150 so that the oil drain port 1428 is connected with the oil drain port 1150. The filter component 1400 discharges the filtered oil through the oil drain port 1428, and then the oil is discharged from the range hood body 1000 through the oil drain port 1150. By inserting the oil drain port 1428 into the oil drain port 1150, both the positioning of the filter component 1400 and the discharge of the oil can be achieved.

[0106] Combination Figures 18 to 20 As shown, in some embodiments, the filtering component 1400 includes a filter 1410 and a filter frame 1420, wherein the filter frame 1420 is provided with an oil collecting tank 1427, an oil drain port 1428 is provided on the filter frame 1420 and the oil drain port 1428 is connected to the oil collecting tank 1427, and the filter 1410 is provided on the filter frame 1420 and located in the oil collecting tank 1427.

[0107] 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 the 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 1428.

[0108] Continue to combine Figures 18 to 20 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 groove 1427 and an oil drain port 1428 are enclosed between the first frame 1421 and the second frame 1422. Through such a setting, the assembly between the filter frame 1420 and the filter 1410 is facilitated on the basis of forming the oil collecting groove 1427 and the oil drain port 1428. 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 and the oil drain port 1428 can be enclosed. At this time, the filter 1410 is located in the oil collecting tank 1427.
