[0052] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. 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.

[0056] This application proposes a desktop range hood 100, combined with Figure 1 and Figure 2 As shown, the desktop range hood 100 includes a body 1000 and an air inlet cover 2000. The air inlet cover 2000 and the body 1000 are movably connected, so that the air inlet cover 2000 can change its position relative to the body 1000. The air inlet cover 2000 is provided with an air inlet 2100. When the desktop range hood 100 sucks oil smoke, the oil smoke enters the interior of the desktop range hood 100 through the air inlet 2100 and is then discharged. Changing the position of the air inlet cover 2000 can change the position of the negative pressure zone to ensure the oil smoke suction effect, thereby adapting to more usage scenarios.

[0057] Specifically, the body 1000 constitutes the skeleton structure of the desktop range hood 100. The body 1000 can be made of metal material or plastic material. It can be an integrated structure or a split structure connected to each other. When the desktop range hood 100 is placed on the desktop, the desktop range hood 100 can be supported on the desktop by the body 1000, and the body 1000 is stationary relative to the desktop. The air inlet hood 2000 is connected to the body 1000, and the air inlet hood 2000 is provided with an air inlet 2100. The desktop range hood 100 draws in oil smoke through the air inlet 2100. It can be understood that the space near the air inlet 2100 of the external environment is regarded as the smoking area. When the desktop range hood 100 is working, a negative pressure is formed in the smoking area. After the oil smoke flows to the smoking area, it can be sucked into the interior of the desktop range hood 100 (the oil smoke enters through the air inlet 2100). When using the desktop range hood 100, the oil smoke may not be well aligned with the smoking area due to differences in the placement environment, type of cookware, wind direction, etc. In order to improve the oil smoke suction effect of the desktop range hood 100, the air inlet hood 2000 is designed to be aligned with the machine in this embodiment. The body 1000 is movably connected. The movable connection here means that the air inlet hood 2000 is fixed to the body 1000, and the air inlet hood 2000 is movable relative to the body 1000, so that the position of the air inlet hood 2000 relative to the body 1000 changes. Since the air inlet hood 2000 is provided with an air inlet 2100, when the position of the air inlet hood 2000 relative to the body 1000 changes, the corresponding smoking area also changes synchronously. In this way, the position of the air inlet hood 2000 can be adjusted according to the actual usage scenario, so that as much oil smoke as possible is aligned with the smoking area, or the smoking area is aligned with the oil smoke, thereby ensuring the suction effect of the oil smoke, with a high degree of freedom of use, and adaptable to different usage scenarios.

[0058] The air intake cover 2000 can be movably connected to the body 1000 in a variety of ways, such as a slidable connection between the air intake cover 2000 and the body 1000, or a rotatable connection between the air intake cover 2000 and the body 1000. When the air intake cover 2000 and the body 1000 are rotatably connected, the air intake cover 2000 can swing back and forth relative to the body 1000, achieving multi-angle adjustment. For example, the air intake cover 2000 can rotate relative to the body 1000 in a first direction and a second direction, the first direction being opposite to the second direction, thereby achieving reciprocal swing of the air intake cover 2000 relative to the body 1000.

[0059] The desktop range hood 100 extracts and exhausts oil smoke through the fan 4000. The fan 4000 is arranged in the body 1000. For example, the fan 4000 is installed inside the body 1000. The top surface of the body 1000 is provided with an air outlet 1200. The fan 4000 generally includes a volute, a motor and an impeller. The impeller is arranged inside the volute. The motor is driven and connected to the impeller. The motor can drive the impeller to rotate at high speed. The high-speed rotation of the impeller causes the oil smoke to enter the air inlet cover 2000 from the air inlet 2100, and then enter the body 1000 and flow through the fan 4000 and be discharged from the air outlet 1200. Since the air intake cover 2000 needs to be movable relative to the main body 1000 to adjust its position, installing the fan 4000 on the main body 1000 can reduce the weight of the air intake cover 2000, making it easier to adjust the position of the air intake cover 2000. Moreover, once the air intake cover 2000 is adjusted to the target position, it is less likely to change position due to gravity. In addition, installing the fan 4000 on the main body 1000 makes the main body 1000 and the fan 4000 relatively heavy. When the main body 1000 is placed on the table, the entire tabletop range hood 100 is placed more stable and less likely to fall over. At this time, it is also possible to adjust the position of the air intake cover 2000 with one hand, making it more convenient to use the tabletop range hood 100.

[0060] Combine Figure 1 As shown, in some embodiments, when the air inlet hood 2000 is rotated to the extreme position along the first direction, the air inlet hood 2000 is tilted upward relative to the fuselage 1000. For example, when the air inlet hood 2000 is rotated from bottom to top to the extreme position, the air inlet hood 2000 is tilted upward from the fuselage 1000, and an angle space is formed between the air inlet hood 2000 and the fuselage 1000. The angle space has a certain smoke-absorbing effect, further enhancing the suction effect of oil smoke.

[0061] Continue to combine Figure 1 As shown, in some embodiments, when the air inlet cover 2000 is rotated to the extreme position along the second direction, the air inlet cover 2000 is fitted into the body 1000. For example, when the air inlet cover 2000 is rotated from top to bottom to the extreme position, the air inlet cover 2000 is vertically arranged. At this time, the air inlet cover 2000 is fitted into the body 1000, completing the storage of the desktop range hood 100 and reducing the space occupied by the desktop range hood 100 when stored.

[0062] Combine Figures 2 to 11As shown, in some embodiments, the air inlet hood 2000 is provided with an air inlet hood exhaust port 2200, and the fuselage 1000 is provided with a fuselage air inlet 1100, and the air inlet hood exhaust port 2200 is connected with the fuselage air inlet 1100, that is, the air inlet hood 2000 is rotatably connected to the fuselage 1000, and the air inlet hood exhaust port 2200 is connected with the fuselage air inlet 1100, so that the oil smoke enters the air inlet hood 2000 from the air inlet port 2100 and leaves the air inlet hood 2000 from the air inlet hood exhaust port 2200, and the oil smoke leaving the air inlet hood 2000 from the air inlet hood exhaust port 2200 enters the interior of the fuselage 100 from the fuselage air inlet 1100, and finally flows through the fan 4000 and is discharged to the external environment from the air outlet 1200.

[0063] The air inlet cover 2200 has a first side 2210 and a second side 2220 opposite to each other along the rotation direction of the air inlet cover 2000. When the air inlet cover 2000 rotates relative to the fuselage 1000, a gap is easily formed between the first side 2210 and the fuselage air inlet 1100, and a gap is also easily formed between the second side 2220 and the fuselage air inlet 1100. For this reason, a first telescopic seal 5100 and a second telescopic seal 5200 are provided in this embodiment. The seal 5200 is a component that can both expand and compress, as well as seal. For example, the first and second telescopic seals 5100 and 5200 are elastic components that can elastically deform, and elastic deformation can achieve expansion and compression. For another example, the first and second telescopic seals 5100 and 5200 are made of rubber or silicone, respectively. Thus, the first and second telescopic seals 5100 and 5200 constitute elastic components that can expand and compress. The first telescopic seal 5100 connects the fuselage 1000 and the air inlet cover 2000, while the second telescopic seal 5200 connects the fuselage 1000 and the air inlet cover 2000. The first telescopic seal 5100 seals the gap between the first side 2210 and the fuselage air inlet 1100, while the second telescopic seal 5200 seals the gap between the second side 2220 and the fuselage air inlet 1100.

[0064] When the air inlet cover 2000 rotates relative to the fuselage 1000, the air inlet cover 2000 drives the first telescopic seal 5100 and the second telescopic seal 5200 to move. The first telescopic seal 5100 is extended or compressed accordingly to ensure the sealing between the first side 2210 and the fuselage air inlet 1100. The second telescopic seal 5200 is extended or compressed accordingly to ensure the sealing between the second side 2220 and the fuselage air inlet 1100. The extension or compression of the first telescopic seal 5100 and the second telescopic seal 5200 adapts to the position change caused by the rotation of the air inlet cover 2000 to ensure the sealing of the gap.

[0065] Combine Figures 12 to 15 As shown, in some embodiments, the first side 2210 exposes the body air inlet 1100 when the air inlet cover 2000 rotates along the second direction. By such a setting, the rotation range of the air inlet cover 2000 can be increased. Similarly, the second side 2220 exposes the body air inlet 1100 when it rotates along the first direction, which can also increase the rotation range of the air inlet cover 2000 and is not limited by the size of the body air inlet 1100, thereby further improving the flexibility of use of the desktop range hood 100. It can be understood that if the second side 2220 cannot expose the fuselage air inlet 1100 (is inside the fuselage air inlet 1100) when the air inlet cover 2000 rotates along the first direction, and the first side 2210 cannot expose the fuselage air inlet 1100 (is inside the fuselage air inlet 1100) when the air inlet cover 2000 rotates along the second direction, then the rotation range of the air inlet cover 2000 is limited by the size of the fuselage air inlet 1100, and the size of the fuselage air inlet 1100 is generally not too large, thus limiting the rotation range of the air inlet cover 2000.

[0066] When the air inlet cover 2000 rotates along the first direction, the first side 2210 gradually approaches the fuselage air inlet 1100, and the air inlet cover 2000 drives the first telescopic seal 5100 to compress, while the second side 2220 gradually moves away from the fuselage air inlet 1100 and exposes the fuselage air inlet 1100, and the air inlet cover 2000 drives the second telescopic seal 5200 to extend. During this process, the compression of the first telescopic seal 5100 and the extension of the second telescopic seal 5200 provide avoidance for the rotation of the air inlet cover 2000, and at the same time achieve the sealing of the gap between the first side 2210 and the fuselage air inlet 1100, and the gap between the second side 2220 and the fuselage air inlet 1100.

[0067] When the air inlet cover 2000 rotates in a second direction opposite to the first direction, the first side 2210 gradually moves away from the fuselage air inlet 1100 and exposes the fuselage air inlet 1100, and the air inlet cover 2000 drives the first telescopic seal 5100 to extend, while the second side 2220 gradually approaches the fuselage air inlet 1100, and the air inlet cover 2000 drives the second telescopic seal 5200 to compress. During this process, the extension of the first telescopic seal 5100 and the compression of the second telescopic seal 5200 provide avoidance for the rotation of the air inlet cover 2000, and at the same time achieve the sealing of the gap between the first side 2210 and the fuselage air inlet 1100, and the gap between the second side 2220 and the fuselage air inlet 1100.

[0068] For example, combined with Figures 16 to 19As shown, the air inlet cover 2000 can be rotated up and down relative to the fuselage 1000, and thus can swing back and forth up and down relative to the fuselage 1000. The upper edge of the air inlet cover exhaust port 2200 constitutes a first side 2210, and the lower edge of the air inlet cover exhaust port 2200 constitutes a second side 2220. A gap is easily formed between the first side 2210 and the fuselage air inlet 1100 (the upper side), and a gap is easily formed between the second side 2220 and the fuselage air inlet 1100 (the lower side). The first telescopic seal 5100 connects the fuselage 1000 and the air inlet cover 2000 and seals the gap between the first side 2210 and the fuselage air inlet 1100 (the upper side). The second telescopic seal 5200 connects the fuselage 1000 and the air inlet cover 2000 and seals the gap between the second side 2220 and the fuselage air inlet 1100 (the lower side). When the air inlet cover 2000 rotates along the first direction (from bottom to top), the first side 2210 gradually approaches the fuselage air inlet 1100 (the upper side), and the air inlet cover 2000 drives the first telescopic seal 5100 to compress, while the second side 2220 gradually moves away from the fuselage air inlet 1100 (the lower side) and the second side 2220 is exposed from the fuselage air inlet 1100, and the air inlet cover 2000 drives the second telescopic seal 5200 to extend. When the air inlet cover 2000 rotates in a second direction (from top to bottom) opposite to the first direction, the first side 2210 gradually moves away from the fuselage air inlet 1100 (the upper side) and the first side 2210 is exposed from the fuselage air inlet 1100, and the air inlet cover 2000 drives the first telescopic seal 5100 to extend, while the second side 2220 gradually approaches the fuselage air inlet 1100 (the lower side), and the air inlet cover 2000 drives the second telescopic seal 5200 to compress.

[0069] Combine Figure 4 、 Figure 5 as well as Figures 8 to 11As shown, in some embodiments, the air inlet cover 2000 includes an exhaust net 2300, which is arranged at the air inlet cover exhaust port 2200, and the exhaust net 2300 protrudes toward the fuselage air inlet 1100 and is inserted into the fuselage air inlet 1100, the first telescopic seal 5100 is arranged on the outside of the exhaust net 2300, and the second telescopic seal 5200 is arranged on the outside of the exhaust net 2300. The outside means the side facing away from the inside of the air inlet cover 2000. Since the first telescopic seal 5100 can be extended and compressed, the second telescopic seal 5200 can be extended and compressed, and the extension and compression of the first telescopic seal 5100 and the second telescopic seal 5200 occur with the rotation of the air inlet cover 2000. By setting the exhaust net 2300, the first telescopic seal 5100 and the second telescopic seal 5200 are set on the outside of the exhaust net 2300, and the exhaust net 2300 is protruding and inserted into the fuselage air inlet 1100, so that the first telescopic seal 5100 and the second telescopic seal 5200 will move along the surface of the exhaust net 2300 during the extension and contraction process, and will not protrude into the air inlet cover exhaust port 2200 or the fuselage air inlet 1100, thereby avoiding obstruction to the airflow.

[0070] Combine Figure 5 、 Figure 9 and Figure 11 As shown, in some embodiments, the air inlet cover 2000 has a first abutting portion 2410, and the body 1000 has a third abutting portion 1510. When the air inlet cover 2000 rotates to the extreme position along the first direction, the first abutting portion 2410 and the third abutting portion 1510 clamp the first telescopic seal 5100. By clamping the first telescopic seal 5100 by the first abutting portion 2410 and the third abutting portion 1510, a buffer is provided when the air inlet cover 2000 rotates to the extreme position along the first direction, thereby avoiding collision between the air inlet cover 2000 and the body 1000, and improving the texture of the desktop range hood 100.

[0071] Similarly, the air inlet cover 2000 has a second abutting portion 2420, and the body 1000 has a fourth abutting portion 1520. When the air inlet cover 2000 rotates to the extreme position along the second direction, the second abutting portion 2420 and the fourth abutting portion 1520 clamp the second telescopic seal 5200. By clamping the second telescopic seal 5200 by the second abutting portion 2420 and the fourth abutting portion 1520, a buffer is provided when the air inlet cover 2000 rotates to the extreme position along the second direction, thereby avoiding collision between the air inlet cover 2000 and the body 1000, and improving the texture of the desktop range hood 100.

[0072] Combine Figure 5As shown, in some embodiments, the first telescopic seal 5100 is designed as a hollow structure to facilitate compression and extension. Similarly, the second telescopic seal 5200 is also designed as a hollow structure to facilitate compression and extension. For example, the first telescopic seal 5100 is a hollow structure made of silicone with elastic deformation properties, which facilitates extension and compression. The second telescopic seal 5200 is a hollow structure made of silicone with elastic deformation properties, which facilitates extension and compression.

[0073] In some embodiments, a damping mechanism 3000 is provided between the fuselage 1000 and the air inlet cover 2000. The damping mechanism 3000 is used to generate damping when the air inlet cover 2000 rotates. Damping can be understood as resistance. Through the setting of the damping mechanism 3000, the air inlet cover 2000 is damped when it rotates relative to the fuselage 1000, which can keep the air inlet cover 2000 in the corresponding position, preventing the air inlet cover 2000 from accidentally leaving the current position without human control.

[0074] Specifically, combined Figures 5 to 11 as well as Figures 16 to 19 As shown, the damping mechanism 3000 includes an arc-shaped groove 3100 and a slider 3200. One of the arc-shaped groove 3100 and the slider 3200 is set on the fuselage 100, and the other of the arc-shaped groove 3100 and the slider 3200 is set on the air inlet cover 2000. The slider 3200 abuts against the arc-shaped groove 3100, that is, the slider 3200 and the arc-shaped groove 3100 cooperate with each other to generate an interaction force. This interaction force can maintain the relative position between the slider 3200 and the arc-shaped groove 3100. When the air hood 2000 rotates relative to the body 1000, the force applied by the user overcomes the interaction force between the arc groove 3100 and the slider 3200, and the arc groove 3100 and the slider 3200 can slide relative to each other. Damping is generated when the arc groove 3100 and the slider 3200 slide relative to each other. When the air inlet hood 2000 rotates to the target position, the arc groove 3100 and the slider 3200 are relatively stationary, and the interaction force between the arc groove 3100 and the slider 3200 enables the air inlet hood 2000 to maintain its current position.

[0075] For example, damping mechanisms 3000 are respectively provided at both ends along the extension direction of the rotation axis of the air inlet cover 2000, the arc groove 3100 is provided on the fuselage 1000, and the slider 3200 is provided on the air inlet cover 2000. When the air inlet cover 2000 is assembled to the fuselage 1000, the slider 3200 abuts against the arc groove 3100. By providing the damping mechanisms 3000 at the relative ends, the rotation feel of the air inlet cover 2000 is better and the position of the air inlet cover 2000 is maintained more effectively.

[0076] Further, combined with Figures 2 to 9As shown, in some embodiments, along the extension direction of the rotation axis of the air inlet cover 2000, the fuselage 1000 is provided with blocks 1600 at opposite ends of the fuselage air inlet 1100. When the air inlet cover 2000 is assembled with the fuselage 1000, the air inlet cover 2000 is inserted between the blocks 1600 at opposite ends, so that the air inlet cover outlet 2200 is connected to the fuselage air inlet 1100. The blocks 1600 at opposite sides realize the connection between the air inlet cover outlet 2200 and the fuselage air inlet 1100. The air inlet cover 2000 is mounted on the block 1600 to achieve a rotatable connection with the fuselage 1000 (the block 1600 is mounted on each end of the air inlet cover outlet 2200). In other words, the air inlet cover 2000 is rotatably connected to the fuselage 1000. The arcuate groove 3100 is provided on the block 1600 and the slider 3200 is provided on the air inlet cover 2000. When the air inlet cover 2000 rotates, the slider 3200 is driven to slide in the arcuate groove 3100. The rotation range of the air inlet cover 2000 is determined by the length of the arcuate groove 3100. Since the slider 3200 can slide in the arcuate groove 3100, the air inlet cover 2000 can be rotated to any angle within the length range of the arcuate groove 3100.

[0077] Combine Figure 4 As shown, in some embodiments, the body 1000 is provided with a first guide cavity 1310, a second guide cavity 1320, and a third guide cavity 1330. The first guide cavity 1310, the second guide cavity 1320 and the third guide cavity 1330 are connected in sequence, and the first guide cavity 1310, the second guide cavity 1320 and the third guide cavity 1330 form a U-shaped arrangement. The inlet of the fan 4000 is connected with the third guide cavity 1330, and the air inlet 2100 is connected with the first guide cavity 1310. When the desktop range hood 100 is working, the oil smoke enters the air inlet cover 2000 from the air inlet 2100, and flows through the first guide cavity 1310, the second guide cavity 1320 and the third guide cavity 1330 in sequence and enters the fan 4000, and is then discharged from the fan 4000 and discharged to the external environment through the air outlet 1200.

[0078] The application environment of the desktop range hood 100 is close to the user. The noise generated when the desktop range hood 100 is in operation is easily transmitted to the user, and the noise transmitted to the user can easily cause discomfort. For this reason, in this embodiment, the first guide chamber 1310, the second guide chamber 1320 and the third guide chamber 1330 are designed to be arranged in a U-shape to form a U-shaped flow channel. The U-shaped flow channel has a corner portion, and the flow direction of the oil smoke needs to change many times during the transmission process, so that the propagation path of the noise also changes, thereby achieving noise attenuation, which helps to reduce the noise of the desktop range hood 100. In addition, the U-shaped arrangement of the first guide chamber 1310, the second guide chamber 1320 and the third guide chamber 1330 extends the length of the flow channel in a limited space, which is also conducive to achieving noise attenuation.

[0079] In addition, the first guide cavity 1310, the second guide cavity 1320 and the third guide cavity 1330 are designed to be arranged in a U-shape to form a U-shaped flow channel, which extends the path of oil fume transmission and realizes the condensation of oil fume. Combined with the formation of the corner portion, the oil fume separation effect before the oil fume reaches the fan 4000 is improved (reducing the content of oil mist particles in the oil fume), thereby preventing the fan 4000 from adhering to more oil and affecting the performance of the fan 4000.

[0080] Furthermore, the first guide chamber 1310 is arranged on one side of the axial direction of the fan 4000, the third guide chamber 1330 is arranged on the other side of the axial direction of the fan 4000, and the second guide chamber 1320 is arranged on one side of the radial direction of the fan 4000, so that the second guide chamber 1320 is located between the first guide chamber 1310 and the third guide chamber 1330, one end of the second guide chamber 1320 is connected to the first guide chamber 1310, and the other end of the second guide chamber 1320 is connected to the third guide chamber 1330. By such an arrangement, the U-shaped flow channel formed by the first guide cavity 1310, the second guide cavity 1320 and the third guide cavity 1330 clamps the fan 4000. When the size of the desktop range hood 100 remains unchanged, the second guide cavity 1320 utilizes the axial space occupied by the fan 4000 to ensure that the second guide cavity 1320 has a certain length, which is more conducive to noise reduction and condensation of oil smoke. In other words, the second guide cavity 1320 utilizes the axial space occupied by the fan 4000, which is conducive to reducing the size of the desktop range hood 100.

[0081] Continue to combine Figure 4 As shown, in some embodiments, the body 1000 includes an oil collecting box 1400, which is arranged below the fan 4000 and is used to receive the oil discharged from the fan 4000. The second guide chamber 1320 is arranged between the oil collecting box 1400 and the fan 4000, that is, the second guide chamber 1320 is located below the fan 4000 and above the oil collecting box 1400. When the desktop range hood 100 is in use, the fan 4000 will adhere to the oil, and the oil will flow downward under the action of gravity. Generally, an oil leakage hole (not shown in the figure) is provided on the volute of the fan 4000. The oil is discharged from the oil leakage hole and flows to the oil collecting box 1400, and is received by the oil collecting box 1400 and temporarily stored. Since the second guide cavity 1320 is arranged between the fan 4000 and the oil collecting box 1400, when the oil smoke flows through the second guide cavity 1320, the oil smoke blows through the oil on the oil collecting box 1400. The oil can enhance the cooling and solidification of the oil mist particles in the oil smoke, thereby enhancing the separation of the oil smoke and more effectively reducing the content of oil mist particles in the oil smoke.
