Figures 1-13

[0046] ​​The embodiment includes the features of the embodiment five, and is different from the embodiment five that the desktop range hood in the utility model has rotation function, specifically, the sliding end 17 and the sliding surface 31 are abutted and slid by the rotation assembly 4, the rotation of the smoke suction assembly 1 relative to the base 3 is realized, wherein the abutment of the sliding end 17 and the sliding surface 31 effectively improves the overall sealing property of the equipment, ensures the seamless connection between the smoke suction assembly 1 and the base 3, effectively prevents the risk that the oil fume enters the wire passing channel 150 and the wire passing hole 160 and contacts the electric wire from the connecting portion; further, in the embodiment, the sliding surface 31 is arc-shaped in cross section, the smoke suction assembly 1 can be adjusted along the arc-shaped track of the sliding surface 31 when the position is adjusted, so that the smoke suction assembly 1 can be adjusted at a certain angle, and the smoothness and stability of the smoke suction assembly 1 relative to the base 3 are improved, and the shaking or instability phenomenon caused by the position adjustment is avoided; further, in other embodiments, the sliding surface 31 is spherical in cross section; further, in the embodiment, the rotation center of the rotation assembly 4 coincides with the center of the cross section of the sliding surface 31, the setting ensures that the smoke suction assembly 1 can keep the best balance and stability during rotation, and can also reduce the additional stress and wear caused by eccentricity, thereby prolonging the service life of the equipment.

[0047] Embodiment seven: further, as shown in Figures 1-13 The wire passing hole 160 is provided at least two, and the two wire passing holes 160 are respectively located on the two sides of the rotation assembly 4.

[0048] The embodiment includes the features of the embodiment six, and is different from the embodiment six that the utility model sets up at least two wire passing holes 160 in structure, and the wire passing holes 160 are respectively located on the two sides of the rotation assembly 4, the setting ensures that the electric wire can keep good state all the time even when the smoke suction assembly 1 rotates relative to the base 3. Specifically, the setting of the multiple wire passing holes makes the electric wire form a more reasonable wiring path inside the equipment, and through the separation and guiding effect of the multiple wire passing holes 160, the problem that the electric wire is excessively bent and wound in the single wire passing hole 160 is avoided; further, by setting the wire passing hole 160 close to the two sides of the rotation assembly 4, the electric wire can be arranged inside the equipment with the smallest bending radius and the largest freedom, thereby reducing the friction and wear between the electric wire and other components inside the equipment.

[0049] Embodiment eight: further, as shown in Figures 1-13The one shown in the table top range hood, wherein the fairing 1221 is provided with fairing body 12213, the fairing body 12213 cross-sectional width gradually increases along the axial direction from the smoke suction port 111 to the discharge port 112 direction, the fairing body 12213 cross-section is tapered, the taper cross-section angle γ range is 60°-120°, the discharge assembly 11 is also provided with the discharge assembly cavity 114 which is communicated with the smoke suction port 111 and the discharge port 112.

[0050] The embodiment includes the characteristics of embodiment seven, and is different from embodiment seven, in the utility model, further, this setting also allows the user to directly flush the discharge assembly cavity 114 with water on the side of the smoke suction port 111, when the user flushes the inside of the discharge assembly 11 with water from the side of the smoke suction port 111, the fairing 1221 can seal the connecting gap 123, similarly, when the water flow enters from the smoke suction port 111, the rotating part 122 is rotated to form suction, so that the water flow can move along the surface of the fairing 1221 to the discharge port 112 direction, so as to cross the connecting gap 123 and finally discharge from the discharge port 112, effectively prevent the water flow from flowing back into the fairing 1221 and entering the inside of the driving part 121 through the connecting gap 123, realize the effect of directly cleaning the inside of the discharge assembly 11 without disassembling the driving assembly 12, avoid the problem that the traditional table top range hood needs to be disassembled after the driving part 121 can be cleaned, thereby simplifying the cleaning process; further, in the process of flushing water to the side of the smoke suction port 111, the rotating part 122 is rotated to the smoke suction direction, which can effectively increase the water flow velocity, thereby realizing more effective cleaning effect of the discharge assembly cavity 114; further, by setting the fairing body 12213 as an axially expanding tapered structure, and limiting the range of taper cross-section angle α to 60°-120°, it is helpful to guide the water flow to form a stable parabolic trajectory, so that the water flow is farther, or used to guide the oil fume to be farther away from the connecting gap 123, to ensure that the oil fume or water flow can smoothly cross the connecting gap 123 and discharge from the discharge port 112; further, if the angle α is less than 60°, the taper angle is too gentle, the water flow cannot effectively form a parabolic trajectory due to lack of enough inclined surface guidance, resulting in part of the water flow flowing into the connecting gap 123, if the angle α is greater than 120°, the taper surface of the fairing body 12213 is too inclined, causing the water flow to produce turbulence or collide with the inner wall of the discharge assembly cavity 114 to form a rebound when passing, increasing the risk of water flow entering the driving part 121, at the same time, it also causes the oil fume to form a turbulent phenomenon, resulting in the oil fume possibly not moving along the predetermined trajectory and entering the connecting gap 123; further, in some embodiments, the outer wall of the fairing body 12213 can also be arc-shaped to better guide the water flow to cross the connecting gap 123; further, in the embodiment, the taper cross-section angle γ is 60°.

[0051] Example 9: Further, such as Figures 1-13 The tabletop range hood shown has a flow guide hood 1221 located near the drive unit 121 and also has a shielding end 12212 arranged along the periphery. The shielding end 12212 extends axially along the drive unit 121. The drive unit 121 has a protruding rotating part step 1211 on its periphery. The distance S1 from the shielding end 12212 to the rotating part step 1211 is between 1.5mm and 2.5mm.

[0052] This embodiment includes features of Embodiment Eight, but differs from Embodiment Eight in that, in this utility model, the flow guide 1221 is further provided with a circumferentially arranged shielding end 12212 on the side near the drive unit 121. This shielding end 12212 extends axially along the drive unit 121 and is located at the opening of the connection gap 123. This arrangement, by adding an additional shielding structure to the circumference of the flow guide 1221, further enhances the protection capability of the connection gap 123. Specifically, the shielding end 12212 can effectively prevent oil fumes or water from entering the connection gap 123 from the side, working in conjunction with the flow guide body 1221. The shielding effect of part 3 ensures that even under multi-angle smoke exhaust or rinsing conditions, oil fumes or moisture will not seep into the drive unit 121, thereby greatly reducing electrical short circuits and other potential safety hazards. Furthermore, in this utility model, the drive unit 121 is provided with a protruding rotating part step 1211 on its periphery, and the distance S1 from the shielding end 12212 to the rotating part step 1211 is between 1.5 mm and 2.5 mm. This setting reduces the space in which oil fumes or water can enter the connection gap 123, thereby effectively preventing oil fumes or moisture from entering the drive unit 121 and improving the safety performance of the entire smoke extraction assembly. Specifically, when the distance S1 between the shielding end 12212 and the rotating part step 1211 is set to between 1.5 mm and 2.5 mm, it ensures that the shielding end 12212 can block the connection gap 123 as much as possible, thereby preventing oil fumes or moisture from entering the connection gap 123. Furthermore, this setting also allows the rotating part 122 to rotate normally relative to the driving part 121, avoiding the situation where the rotating part step 1211 and the shielding end 12212 collide due to the vibration of the smoke extraction assembly 1, which would increase the rotational resistance of the rotating part 122, and effectively reduces the friction between the rotating part 122 and the driving part 121. Wear; further, if S1 is less than 1.5 mm, the distance between the shielding end 12212 and the rotating part step 1211 is too small, which may cause friction or collision between the two during rotation, increasing the noise and vibration of the equipment during operation, and even causing the components to wear more quickly and shorten their service life. If S1 is greater than 2.5 mm, the excessive distance will cause the shielding end 12212 to be unable to effectively cover the connection gap 123, increasing the risk of oil fumes or moisture seeping into the drive part 121. Further, in this embodiment, the distance S1 from the shielding end 12212 to the rotating part step 1211 is 1.5 mm.

[0053] Further, as shown in Figures 1-13 The smoke suction assembly 1 further comprises a control assembly 16 for controlling the operation of the driving assembly 12, the control assembly 16 is provided with a control assembly connecting end 166 connected to the driving part 121 away from the rotating part 122, the diameter of the control assembly connecting end 166 is smaller than the diameter of the driving part 121, the control assembly connecting end 166 is provided with a protruding clamping connecting end, and the driving part 121 is located in a connecting groove for the clamping connecting end to extend into.

[0054] The embodiment includes the features of the ninth embodiment, and is different from the ninth embodiment in that, in the utility model, the driving part 121 guides the wire into the control assembly 16 through the inside of the control assembly connecting end 166, which optimizes the internal structure layout and avoids the contact between the wire and the oil fume or water, thereby improving the safety and stability of the electrical connection; further, since the diameter of the control assembly connecting end 166 is smaller than the diameter of the driving part 121, this reduces the probability of the oil fume or water passing through the connecting part of the driving part 121 and the control assembly connecting end 166 during the process of the oil fume or water flowing to the discharge port 112 through the deflector 1221, so that the oil fume or water flows over the connecting part of the driving part 121 and the control assembly connecting end 166, effectively preventing the oil fume or water from passing through or directly impacting the connecting part of the driving part 121 and the control assembly connecting end 166; further, through the cooperation of the clamping connecting end and the connecting groove, not only a stable mechanical connection is achieved, but also an effective seal is formed, which prevents the oil fume or water from entering the inside of the control assembly 16 through the connecting part of the driving part 121 and the control assembly connecting end 166, thereby improving the waterproof performance and service life of the overall device.

[0055] Further, as shown in Figures 1-13 The smoke suction port 111 is provided with a fragrance assembly 1111, and the driving assembly 12 drives the oil fume to be sucked into the smoke suction port 111 and flow through the fragrance assembly 1111, so that the fragrance is mixed with the oil fume and then discharged through the discharge port 112 to diffuse into the air.

[0056] The embodiment includes the features of the tenth embodiment, and is different from the tenth embodiment in that, in the utility model, the fragrance assembly is arranged at the smoke suction port 111, and the oil fume is driven by the driving assembly 12 to be sucked into the smoke suction port 111 and flow through the fragrance assembly 1111, and finally the fragrance is mixed with the oil fume and then discharged through the discharge port 112 to diffuse into the air, thereby covering the odor of the oil fume, which not only effectively solves the problem of odor generated by the direct discharge of the oil fume during cooking, but also improves the comfort of the entire home environment.

[0057] Further, as shown in Figures 1-13The control assembly 16 is fixed in the middle of the discharge port 112, a discharge channel 1123 is formed between the discharge port 112 and the control assembly 16, the discharge channel 1123 is arranged in a ring shape, the driving assembly 12 drives the oil fume to be sucked from the smoke suction port 111 and discharged from the discharge channel 1123 at an angle.
