However, the air duct inside the traditional range hood will accumulate a large amount of oil and impurities after a period of use, so it is necessary to clean the inside of the range hood regularly. However, the traditional range hood is still inconvenient to clean. First, the existing range hood needs to be disassembled before cleaning, and then the air duct is cleaned, so as to prevent water from entering the motor, which will complicate the entire cleaning process and bring inconvenience to the user.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] Example 1: As Figures 1-10 A washable smoking assembly is shown, comprising a smoking assembly 1, wherein the smoking assembly 1 includes an exhaust assembly 11 and a drive assembly 12. The exhaust assembly 11 has a smoking port 111 at one end, an exhaust port 112 at the other end, and an exhaust assembly cavity 114 connecting the smoking port 111 and the exhaust port 112. The drive assembly 12 is fixed to the exhaust assembly cavity 114, and the drive assembly 12 includes a drive part 121 for power supply and a rotating part 122 rotatably connected to the drive part 121. A connection gap 123 is provided between the rotating part 122 and the driving part 121. The rotating part 122 is provided with a flow guide shroud 1221 for covering the connection gap 123. When water flows from the smoke inlet 111 into the discharge assembly cavity 114 and is discharged from the discharge outlet 112 through the flow guide shroud 1221, the rotating part 122 rotates to form a suction force that drives the water flow to move along the surface of the flow guide shroud 1221 toward the discharge outlet 112, thereby passing over the connection gap 123 and being discharged from the discharge outlet 112.

[0032] In the present application, since the driving part 121 and the rotating part 122 are connected in a rotating manner, there is a connecting gap 123 between the driving part 121 and the rotating part 122, the present application sets a fairing 1221 on the rotating part 122 to wrap the connecting gap 123, so that the connecting gap 123 is located in the fairing 1221, when the user flushes the inside of the exhaust assembly 11 from the side of the smoke inlet 111 with water, the fairing 1221 can play a sealing role on the connecting gap 123, in addition, after the water flow enters from the smoke inlet 111, the rotating part 122 rotates to form suction, so that the water flow can move along the surface of the fairing 1221 to the direction of the exhaust port 112, so as to pass through the connecting gap 123 and finally be discharged from the exhaust port 112, effectively preventing the water flow from flowing back into the fairing 1221 and entering the inside of the driving part 121 through the connecting gap 123, realizing the effect of directly cleaning the inside of the exhaust assembly 11 without disassembling the driving assembly 12, avoiding the problem that the traditional desktop oil fume machine needs to be disassembled after the driving part 121 is disassembled. 121 can be cleaned, thereby simplifying the cleaning process.

[0033] Specifically, the smoking assembly 1 in the present application is combined with the driving assembly 12 through the exhaust assembly 11, and the driving part 121 and the rotating part 122 are connected in a rotating manner, so that the rotating part 122 can rotate relative to the driving part 121. Therefore, there is a connection gap 123 between the rotating part 122 and the driving part 121. For a common table-top range hood smoking assembly, direct washing with water will cause water to flow into the inside of the driving part 121 through the connection gap 123, thereby causing the risk of damage or short circuit of electrical components. Therefore, the driving part 121 has to be disassembled every time it is cleaned, which not only increases the operation complexity of the user, but also brings potential safety hazards. In order to prevent water from entering the inside of the driving part 121, the present application provides a flow guide cover 1221 on the rotating part 122 to wrap the connection gap 123, so that the connection gap 123 is hidden in the flow guide cover 1221. When the user needs to clean the smoking assembly, water can be directly washed from the side of the smoke inlet 111, and at the same time, the rotating part 122 is rotated to form a suction force, so that the water flow flows along the surface of the flow guide cover 1221 to the exhaust port 112, thereby passing through the connection gap 123 and finally being discharged from the exhaust port 112, preventing the water flow from flowing into the inside of the flow guide cover 1221 and entering the driving part 121 through the connection gap 123. This setting allows the user to effectively clean the inside of the exhaust assembly 11 without disassembling any parts, greatly improving the cleaning efficiency and reducing the maintenance time. At the same time, the cleaning method without disassembly is more convenient and fast. Further, the rotation of the rotating part 122 can also prevent the water flow from flowing back to the smoke inlet 111, ensuring that the water flow does not flow back into the flow guide cover 1221 after flowing through the flow guide cover 1221, thereby avoiding the water flow flowing into the connection gap 123. Further, in some embodiments, a water inlet assembly connected with a water pipe can be provided on the side of the smoke inlet 111 of the smoking assembly 1. The water inlet assembly can be detachably connected to the smoking assembly 1. When cleaning is needed, only the water inlet assembly and the water pipe need to be installed, and the driving assembly 12 can be started to perform the washing operation. Further, during the water flushing process to the side of the smoke inlet 111, the rotating part 122 is rotated in the smoke direction, which can effectively increase the water flow speed, thereby achieving more effective cleaning effect on the exhaust assembly cavity 114.

[0034] Embodiment two: further, as shown in Figures 1-10 the water-washable smoking assembly, wherein the flow guide cover 1221 is provided with a flow guide cover body 12213, the connection gap 123 is located in the flow guide cover body 12213, the cross-sectional width of the flow guide cover body 12213 gradually increases along the axial direction from the smoke inlet 111 to the exhaust port 112, and the cross section of the flow guide cover body 12213 is conical, and the conical cross section angle α is in the range of 60°-120°.

[0035] The embodiment includes the features of the first embodiment, and is different from the first embodiment in that the connecting gap 123 is hidden in the fairing body 12213, and the fairing body 12213 is arranged as an axially tapered conical structure, and the conical cross-sectional angle α is limited to a range of 60°-120°, which helps to guide the water flow to form a parabolic trajectory, ensures that the water flow reaches the side closer to the discharge port 112 after leaving the fairing body 12213 by inertia, further prevents the water flow from flowing back into the connecting gap 123, and ensures that the water flow can smoothly flow out of the discharge port 112 after passing through the connecting gap 123; further, if the angle α is less than 60°, the conical angle is too gentle, and the water flow cannot effectively form a parabolic trajectory due to lack of sufficient inclined surface guidance, which increases the risk of part of the water flow flowing into the connecting gap 123, and if the angle α is greater than 120°, the conical surface of the fairing body 12213 is too inclined, which causes the water flow to easily produce turbulence or collide with the inner wall of the discharge assembly cavity 114 to form a rebound when passing through, thereby increasing the risk of the water flow entering the driving part 121; further, in some embodiments, the outer wall of the fairing body 12213 can also be arranged in a certain arc shape to better guide the water flow to form a parabolic trajectory to move closer to the side of the discharge port 112; further, in the embodiment, the conical cross-sectional angle α is 60°.

[0036] Embodiment three: further, as shown in Figures 1-10 the discharge assembly cavity 114 is provided with a first constant diameter section 13 connected with the smoking port 111, a third constant diameter section 15 located between the smoking port 111 and the discharge port 112, and a first variable diameter section 18 connecting the first constant diameter section 13 and the third constant diameter section 15, the diameter of the third constant diameter section 15 is greater than that of the first constant diameter section 13, the connecting gap 123 is located in the third constant diameter section 15, the distance D1 between the outer wall of the fairing 1221 and the inner wall of the first variable diameter section 18, and the distance D2 between the outer wall of the driving part 121 and the inner wall of the third constant diameter section 15, D1 is 1.2-1.5 times of D2.

[0037] The embodiment includes the features of embodiment two, and is different from embodiment two in that, in the present application, the discharge assembly cavity 114 is provided with a first constant-diameter section 13 connected with the smoking port 111, a third constant-diameter section 15 located between the smoking port 111 and the discharge port 112, and a first variable-diameter section 18 connecting the first constant-diameter section 13 and the third constant-diameter section 15, wherein the third constant-diameter section 15 has a larger diameter than the first constant-diameter section 13, the connecting gap 123 is located in the third constant-diameter section 15, the distance D1 between the outer wall of the flow guide cover 1221 and the inner wall of the first variable-diameter section 18, and the distance D2 between the outer wall of the driving part 121 and the inner wall of the third constant-diameter section 15, D1 is 1.2-1.5 times of D2. This arrangement realizes effective acceleration of water flow through reasonable space layout. When water flow enters the narrower third constant-diameter section 15 from the wider first variable-diameter section 18, the water flow speed increases, so that the water flow moves more effectively in the direction of the discharge port 112 over the connecting gap 123. At the same time, the higher flow rate not only helps to remove residues in the discharge assembly cavity 114, improves the cleaning effect, but also reduces the possibility of water retention in the discharge assembly cavity 114, further enhances the waterproof performance. Further, if D1 is less than 1.2 times of D2, the space of the first variable-diameter section 18 will become relatively small, resulting in insufficient acceleration effect of water flow when entering the third constant-diameter section 15, and the water flow speed is not enough to effectively cross the connecting gap 123, increasing the risk of water retention in the discharge assembly cavity 114 or seeping into the driving part 121, reducing the cleaning efficiency and waterproof performance. On the contrary, if D1 is greater than 1.5 times of D2, the excessive first variable-diameter section 18 will cause the annular space of the third constant-diameter section 15 to be excessively compressed, which is easy to make the water flow form turbulent flow after entering the third constant-diameter section 15, thereby changing the direction of the water flow and increasing the risk of water flow entering the connecting gap 123. Further, in the present embodiment, D1 is 1.2 times of D2.

[0038] Embodiment four: further, as shown in Figures 1-10 a washable smoking assembly, wherein the flow guide cover 1221 located close to the driving part 121 side is further provided with a shielding end 12212 arranged along the circumferential side, and the shielding end 12212 is arranged along the axial direction of the driving part 121.

[0039] The embodiment includes the features of embodiment three, and is different from embodiment three in that the fairing 1221 located close to the driving part 121 is further provided with a shielding end 12212 arranged along the circumferential side. The shielding end 12212 is arranged along the axial direction of the driving part 121 and is located at the opening of the connecting gap 123. This arrangement further enhances the protection capability of the connecting gap 123 by adding an additional shielding structure to the circumferential side of the fairing 1221. Specifically, the shielding end 12212 can effectively prevent water flow from entering the connecting gap 123 from the side, ensuring that even in the case of multi-angle flushing, water will not penetrate into the inside of the driving part 121, thereby greatly reducing the risk of electrical short circuit and other potential safety hazards. Further, in some embodiments, the shielding end 12212 extends along the circumferential side of the driving part 121 and is inclined to the driving part 121 side, thereby better shielding the connecting gap 123.

[0040] Embodiment five: further, as shown in Figures 1-10 a washable smoking component, wherein the rotating part 122 is provided with a blade 1222 connected with the fairing 1221. The cross section of the blade 1222 is arranged in an arc shape protruding towards the discharge port 112.

[0041] The embodiment includes the features of embodiment four, and is different from embodiment four in that the rotating part 122 is provided with a blade 1222 connected with the fairing 1221. The cross section of the blade 1222 is arranged in an arc shape protruding towards the discharge port 112. This arrangement optimizes the shape of the blade 1222, so that the water flow can be better guided when passing through the blade 1222. Specifically, the end of the blade 1222 is connected to the end of the fairing extension end 12211, so that the arc-shaped blade 1222 can push the water flow to the side of the discharge port 112 during rotation and form a stable parabolic trajectory. Since the end of the blade 1222 is connected to the end of the fairing extension end 12211, when the water flow leaves the blade 1222, it has already passed the opening of the connecting gap 123, so that the water flow passes through the connecting gap 123 and is discharged from the discharge port 112. Further, the arc-shaped arrangement of the cross section of the blade 1222 also helps to reduce water resistance, making the rotation of the rotating part 122 more stable and efficient during cleaning. Further, the end of the blade 1222 located close to the driving part 121 is arranged in a wave shape. This arrangement causes the water flow to be more disturbed when passing through the wave-shaped end of the blade 1222, thereby producing a stronger turbulent effect, which can more effectively flush away grease and impurities attached to the inner wall of the discharge assembly cavity 114.

[0042] Embodiment six: further, as shown in Figures 1-10The illustration shows a washable smoking assembly, wherein the blade 1222 is inclined from the side of the baffle 1221 near the smoking port 111 to the side near the exhaust port 112, and the central axis of the blade 1222 forms an angle β with the central axis of the baffle 1221, the angle β ranging from 30° to 60°.

[0043] This embodiment includes features of Embodiment 5, but differs from Embodiment 5 in that, in this invention, the blade 1222 is inclined from the side of the guide shroud 1221 near the smoke inlet 111 towards the side near the discharge outlet 112. The central axis of the blade 1222 forms an angle β with the central axis of the guide shroud 1221, with the β angle ranging from 30° to 60°. This setting, by reasonably adjusting the angle of the blade 1222, allows the water flow to obtain optimal guidance and acceleration effects when passing through it. Specifically, when the β angle is set between 30° and 60°, the blade 1222 can effectively guide the water flow to form a stable parabolic trajectory along the surface of the guide shroud 1221 during rotation, and finally cross the connecting gap 123 and be discharged from the discharge outlet 112. This inclination angle setting not only ensures that the water flow has sufficient power to flow along the surface of the guide shroud 1221, but also avoids excessive resistance or turbulence, thereby improving drainage efficiency and cleaning effect. Furthermore, if the β angle is less than 30°, the inclination of the blade 1222 will become more gradual, resulting in water... When the water flows over the blade 1222, it cannot obtain sufficient thrust, thereby reducing the speed at which the water flows further into the discharge assembly cavity 114. When the water flow velocity is too low, it increases the risk of water flowing into the connection gap 123. In addition, a small tilt angle may result in insufficient water flow velocity, which may prevent the water flow from fully flushing the discharge assembly cavity 114 and removing residues inside the discharge assembly cavity 114. Furthermore, if the β angle is greater than 60°, the tilt of the blade 1222 is too large, which will cause the water flow to generate greater resistance and turbulence when passing over the blade, increasing the complexity and instability of the water flow path. In addition, an excessively large tilt angle may cause the water flow to deviate from the predetermined path, and may even cause some water flow to directly impact the drive unit 121, increasing the risk of water infiltration. At the same time, an excessively large tilt angle will also increase the friction between the blade 1222 and the water flow, thereby reducing the overall durability of the drive assembly 12 and may increase the noise and vibration of the drive assembly 12 during operation. Furthermore, in this embodiment, the β angle is 30°.

[0044] Example 7: Further, such as Figures 1-10 The present invention discloses a washable smoking assembly, wherein the smoking assembly 1 further includes a filter 19 fixed to the smoking port 111, the filter 19 being detachably connected to the smoking port 111, and the filter 19 having a pore size of 2-4 mm.

[0045] The embodiment includes the features of embodiment six, and is different from embodiment six in that the smoking assembly 1 further includes a filter screen 19 fixed at the smoking port 111. The filter screen 19 is detachably connected with the smoking port 111, and the aperture of the filter screen 19 is 2-4 mm. This arrangement can effectively intercept large particles of grease and impurities, prevent them from entering the inside of the discharge assembly cavity 114, and reduce the amount of accumulated grease in the discharge assembly cavity 114, thereby reducing the cleaning frequency and difficulty. Further, the detachable connection of the filter screen 19 makes it convenient for the user to disassemble and clean, ensuring that the filter screen always maintains good filtering effect. Further, by setting the aperture of the filter screen 19 to be between 2-4 mm, the filter screen 19 can effectively intercept larger particles without causing excessive resistance to airflow, ensuring efficient operation of the smoking assembly. Further, in the embodiment, the aperture of the filter screen 19 is 2 mm. Further, in some embodiments, the filter screen 19 is fixed to the smoking port 111 by magnetic attraction. Further, in some embodiments, the filter screen 19 is fixed to the smoking port 111 by a buckle structure.

[0046] Embodiment eight: further, as shown in Figures 1-10 a washable smoking assembly, wherein the smoking assembly 1 further includes 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 with the driving part 121 away from the rotating part 122. The diameter of the control assembly connecting end 166 is smaller than that 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.

[0047] The embodiment includes the features of embodiment seven, and is different from embodiment seven in that, in the present application, the driving part 121 guides the electric wire inside the control assembly connecting end 166 to the inside of the control assembly 16. This arrangement not only optimizes the internal structure layout, but also avoids the contact of the electric wire with water, improving the safety and stability of the electrical connection. Further, since the diameter of the control assembly connecting end 166 is smaller than that of the driving part 121, the water flow presents a parabolic flow towards the discharge port 112 during the process of flowing through the deflector 1221 to the discharge port 112, so that the water flow passes over the connection between the driving part 121 and the control assembly connecting end 166, effectively preventing the water flow from flowing through or directly impacting the connection between the driving part 121 and the control assembly connecting end 166. Further, the use of the clamping connecting end and the connecting groove not only achieves stable mechanical connection, but also forms effective sealing, preventing water flow from entering the inside of the control assembly 16 through the connection between the driving part 121 and the control assembly connecting end 166, and improving the waterproof performance and service life of the overall device.

[0048] Example 9: Further, such as Figures 1-10 The present invention discloses a washable smoking assembly, wherein the drive part 121 is provided with a protruding rotating part step 1211 on its periphery, and the distance S1 from the blocking end 12212 to the rotating part step 1211 is between 1.5mm and 2.5mm.

[0049] This embodiment includes the features of Embodiment 8. The difference between Embodiment 8 and Embodiment 8 is that, in this invention, the drive part 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 arrangement reduces the space in which water can flow into the connection gap 123, thereby effectively preventing water from entering the drive part 121 and improving the waterproof performance of the entire smoking assembly. Specifically, when the distance S1 from the blocking end 12212 to the rotating part step 1211 is set between 1.5 mm and 2.5 mm, it ensures that the blocking end 12212 can block the connection gap 123 as much as possible. At the same time, in conjunction with the guide extension end 12211, it can guide the water flow towards the discharge port 112, thereby preventing water 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 blocking end 12212 collide due to the vibration of the smoke assembly 1, which would increase the rotational resistance of the rotating part 122, and can effectively reduce the impact of the vibration. Wear between the rotating part 122 and the driving part 121; 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 moisture seeping into the driving part 121; further, in this embodiment, the distance S1 from the shielding end 12212 to the rotating part step 1211 is 1.5 mm.

[0050] Example 10: This example includes all the features of Examples 1 to 9, except that in this example, the cone cross-section angle α is 120°, D1 is 1.5 times D2, the β angle is 60°, the filter screen 19 has a pore size of 4mm, and the distance S1 from the shielding end 12212 to the rotating part step 1211 is 2.5mm.

[0051] Example 11: This example includes all the features of Examples 1 to 9, except that in this example, the conical cross-section angle α is 80°, D1 is 1.3 times D2, the β angle is 45°, the filter screen 19 has a pore size of 3mm, and the distance S1 from the shielding end 12212 to the rotating part step 1211 is 2mm.

[0052] Embodiment twelve: further, the smoking assembly flushing operation mode, comprising a water-washable smoking assembly, further comprising the following steps:

[0053] S1: driving assembly 12 to rotate in alternating forward and reverse directions for periodic flushing, wherein the rotation speed of the forward rotation is greater than that of the reverse rotation; S2: driving assembly 12 switches to forward high-speed rotation for residual water discharge.

[0054] This embodiment includes all the features of embodiments one to eleven, the difference is that the invention provides a smoking assembly flushing operation mode, first, this flushing operation mode guides the water flow to move in the direction of the discharge port 112 by the forward rotation of the rotating part 122, and then by the reverse rotation to flush the discharge assembly cavity 114 after most of the water flow is discharged, thereby achieving the effect of alternating forward and reverse rotation for periodic flushing of the blade 1222 and the discharge assembly cavity 114, wherein the rotating part 122 rotates in the direction of the blade 1222 inclination is positive. In addition, the impact force of the water flow can effectively remove the residues in the cavity, and the forward high-speed rotation further enhances the drainage effect, and in the process, the rotation speed of the forward rotation is greater than that of the reverse rotation.

[0055] Specifically, first, in the cleaning mode, the discharge assembly cavity 114 is filled with water, and the motor is operated at 2000 rpm for 15 seconds, which will discharge most of the water flow through the discharge port 112, then stop the water supply and reverse 500 rpm for 15 seconds, use the remaining part of the water in the discharge assembly cavity 114 to flush the blade 1222 and the discharge assembly cavity 114, avoid too much water flow into the connecting gap 123 in the flow guide cover 1221 when the rotating part 122 is reversed, and the shielding end 12212 can prevent the water flow from entering the connecting gap 123 during the reverse process. Then make the rotating part 122 rotate forward 2000 rpm for 15 seconds, and then reverse 500 rpm for 15 seconds in turn, and this process lasts for one minute and a half. This alternating forward and reverse rotation not only uses the strong centrifugal force generated by high-speed forward rotation to throw the oil and impurities on the blade 1222 and in the discharge assembly cavity 114 to the side of the discharge port 112 and discharge, but also changes the direction of the water flow by lower-speed reverse rotation, ensuring that the water flow covers all areas in the cavity, avoiding the problem that some corners cannot be effectively cleaned due to fixed water flow path, and also avoiding the problem of large amount of water flow splashing from the smoking port 111. In the process, since the cross section of the blade 1222 is arranged in an arc shape protruding in the direction of the discharge port 112, the guiding effect of the water flow is further enhanced, so that the water flow can form a more stable parabolic trajectory, and finally over the connecting gap 123 and discharged from the discharge port 112.

[0056] In addition, after one and a half minutes of alternating rotation, the drive component 12 switches to a forward high-speed rotation of 3000 rpm for 30 seconds. The main purpose is to quickly expel residual moisture from the discharge component cavity 114. The powerful centrifugal force generated by the high-speed rotation quickly throws out the remaining water, ensuring that there is no water accumulation in the discharge component cavity 114 and preventing bacterial growth or corrosion of metal parts due to moisture retention. At the same time, this high-speed rotation also helps to thoroughly remove stubborn residues adhering to the inner wall of the cavity, further improving the cleaning effect.

[0057] Furthermore, after the entire rinsing process is completed, a buzzer will beep once per second for the last 30 seconds, generating an intermittent audible and visual alert to notify the user that the cleaning process is complete. This invention incorporates a washable fumigation assembly, eliminating the need for frequent disassembly and manual cleaning, significantly reducing maintenance costs and time. Simultaneously, because the entire cleaning process is automated, it also reduces human intervention, improving the safety and reliability of the equipment.

[0058] Example 13: Further, such as Figures 1-11 The desktop range hood shown includes a flushing operation mode for the smoke extraction components.

[0059] This embodiment includes all the features of embodiments one through twelve, the difference being that the present invention applies a washable smoke extraction component and its rinsing operation mode to a desktop range hood. Specifically, a washable smoke extraction component is integrated into the desktop range hood. Through the setting of components such as the guide hood 1221 and blades 1222, water can be effectively prevented from entering the drive unit 121, simplifying the cleaning process and improving the cleaning effect. Furthermore, by combining the rinsing operation mode of the smoke extraction component, the drive component 12 performs periodic rinsing with alternating forward and reverse rotations, and finally discharges residual water through high-speed forward rotation, ensuring that there is no residual water in the cavity. This setting not only solves the problem of inconvenient cleaning of traditional range hoods, but also effectively improves the safety and durability of the equipment. Furthermore, in some embodiments, the desktop range hood is equipped with an automatic flushing component. In actual use, the user only needs to start the cleaning mode, and the smoke extraction component 1 will automatically complete a series of rinsing steps, and notify the user through sound and light prompts after completion. This setting greatly simplifies the user's operation process, reduces maintenance workload, and improves the user experience.

Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
