[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1: Figure 1-10 A washable smoking assembly is shown, comprising a smoking assembly 1, wherein the smoking assembly 1 comprises an exhaust assembly 11 and a driving assembly 12, wherein the exhaust assembly 11 is provided with an inhalation port 111 at one end, an exhaust port 112 at the other end, and an exhaust assembly cavity 114 connecting the inhalation port 111 and the exhaust port 112, wherein the driving assembly 12 is fixed to the exhaust assembly cavity 114, and comprises a driving part 121 for power supply, and a rotating part 122 rotatably connected to the driving part 121 A connection gap 123 is provided between the rotating part 122 and the driving part 121, and the rotating part 122 is provided with a guide cover 1221 for covering the connection gap 123. When water flows into the discharge component cavity 114 from the smoking port 111 and is discharged from the discharge port 112 through the guide cover 1221, the rotating part 122 rotates to form suction to drive the water flow to move along the surface of the guide cover 1221 toward the discharge port 112, so that the water flows across the connection gap 123 and is discharged from the discharge port 112.

[0029] In the present invention, 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 invention arranges a guide cover 1221 on the rotating part 122 for wrapping the connecting gap 123, so that the connecting gap 123 is located inside the guide cover 1221. When the user flushes the inside of the discharge assembly 11 with water from the side of the smoking port 111, the guide cover 1221 can seal the connecting gap 123. In addition, after the water flows into the smoking port 111, the rotating part 122 is closed. The rotation of the moving part 122 creates suction, which enables the water flow to move along the surface of the guide cover 1221 toward the discharge port 112, thereby crossing the connection gap 123 and finally being discharged from the discharge port 112, effectively preventing the water flow from flowing back into the guide cover 1221 and entering the interior of the driving part 121 through the connection gap 123, thereby achieving the effect of directly cleaning the interior of the discharge component 11 without disassembling the drive component 12, avoiding the problem that traditional desktop range hoods need to disassemble the drive part 121 for cleaning, thereby simplifying the cleaning process.

[0030] Specifically, the smoking assembly 1 in the present invention is combined with the driving assembly 12 through the discharge 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 must be a connection gap 123 between the rotating part 122 and the driving part 121. For ordinary desktop range hood smoking assemblies, directly flushing with water will cause moisture to flow into the interior of the driving part 121 through the connection gap 123, thereby causing the risk of damage to electrical components or short circuit. Therefore, the driving part 121 has to be disassembled each time it is cleaned, which not only increases the complexity of the user's operation, but also brings potential safety hazards. In order to prevent moisture from entering the interior of the driving part 121, the present invention provides a guide cover 1221 on the rotating part 122 to wrap the connecting gap 123, so that the connecting gap 123 is hidden in the guide cover 1221. When the user needs to clean the smoking component, he can directly rinse it with water from the side of the smoking port 111. At the same time, the rotating part 122 rotates to form suction, so that the water flow will flow along the surface of the guide cover 1221 toward the discharge port 112, thereby crossing the connecting gap 123 and finally being discharged from the discharge port 112, preventing the water flow from flowing into the guide cover 1221 and entering the driving part 121 through the connecting gap 123. This arrangement allows the user to complete the effective cleaning of the inside of the discharge component 11 without disassembling any parts, greatly improving the cleaning efficiency and reducing the maintenance time. At the same time, there is no need The disassembly cleaning method is more convenient and quick; further, the rotation of the rotating part 122 can also prevent the water from flowing back toward the smoking port 111, ensuring that the water will not flow back into the guide cover 1221 after passing through the guide cover 1221, thereby avoiding the situation where the water flows into the connection gap 123; further, in some embodiments, the smoking component 1 is located on the side of the smoking port 111 and a water inlet component connected to the water pipe can be provided, and the water inlet component can be detachably connected to the smoking component 1. When cleaning is required, it is only necessary to install the water inlet component and the water pipe, and start the driving component 12 to perform the flushing operation; further, in the process of flushing water to the side of the smoking port 111, the rotating part 122 rotates in the smoking direction, which can effectively increase the water flow speed, thereby achieving a more effective cleaning effect on the discharge component cavity 114.

[0031] Embodiment 2: Further, as Figure 1-10 A washable smoking assembly is shown, wherein the deflector 1221 is provided with a deflector body 12213, the connecting gap 123 is located in the deflector body 12213, the cross-sectional width of the deflector body 12213 gradually increases along the axial direction from the smoking port 111 to the discharge port 112, the cross-section of the deflector body 12213 is conical, and the conical cross-sectional angle α ranges from 60° to 120°.

[0032] This embodiment includes the features of the first embodiment, and is different from the first embodiment in that the present invention hides the connection gap 123 in the deflector body 12213, and sets the deflector body 12213 to an axially gradually expanding conical structure, and limits the range of the conical section angle α to 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 through inertia after leaving the deflector body 12213, further prevents the water flow from flowing back into the connection gap 123, and ensures that the water flow can be smoothly discharged from the discharge port 112 after crossing the connection gap 123; further, if the angle α is less than 60°, the cone angle If it is too flat, the water flow will not be able to effectively form a parabolic trajectory due to the lack of sufficient inclined surface guidance, resulting in the risk of part of the water flow flowing into the connecting gap 123. If the angle α is greater than 120°, the conical surface of the deflector body 12213 will be too inclined, causing the water flow to easily generate turbulence when passing through or collide with the inner wall of the discharge component cavity 114 to form a rebound, increasing the risk of water flow entering the drive unit 121; further, in some embodiments, the outer wall of the deflector body 12213 can also be set in a certain arc shape to better guide the water flow to form a parabolic trajectory and move closer to the discharge port 112; further, in this embodiment, the conical section angle α is 60°.

[0033] Embodiment 3: Further, as Figure 1-10 A washable smoking assembly is shown, wherein the discharge assembly cavity 114 is provided with a first constant diameter section 13 connected to 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 larger 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 deflector 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.

[0034] This embodiment includes the features of the second embodiment, and is different from the second embodiment in that, in the present invention, the discharge component cavity 114 is provided with a first constant diameter section 13 connected to 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 diameter of the third constant diameter section 15 is larger 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 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 spatial layout, when the water flow enters the narrower third constant diameter section 15 from the wider first variable diameter section 18, the water flow speed will be increased, so as to more effectively cross the connecting gap 123 and move toward the discharge port 112, and at the same time, the higher The flow rate not only helps to clear the residue in the discharge component cavity 114 and improve the cleaning effect, but also reduces the possibility of water being retained in the discharge component cavity 114, further enhancing the waterproof performance; further, if D1 is less than 1.2 times of D2, then the space of the first variable diameter section 18 will become relatively small, resulting in the water flow failing to obtain sufficient acceleration effect when entering the third constant diameter section 15, and the water flow speed is insufficient to effectively cross the connection gap 123, increasing the risk of water being retained in the discharge component cavity 114 or infiltrating into the drive part 121, reducing the cleaning efficiency and waterproof performance; on the contrary, if D1 is greater than 1.5 times of D2, the excessively large first variable diameter section 18 will cause the annular space of the third constant diameter section 15 to be over-compressed, which will easily cause the water flow to form turbulence after entering the third constant diameter section 15, thereby changing the direction of the water flow and increasing the risk of the water flow entering the connection gap 123; further, in this embodiment, D1 is 1.2 times of D2.

[0035] Embodiment 4: Further, as Figure 1-10 A washable smoking assembly is shown, wherein the deflector 1221 is located near the driving part 121 and is also provided with a shielding end 12212 arranged along the circumferential side, and the shielding end 12212 is extended axially along the driving part 121.

[0036] This embodiment includes the features of embodiment three, and differs from embodiment three in that, in the present invention, the air deflector 1221 is located on a side close to the driving portion 121 and is also provided with a shielding end 12212 arranged along the circumferential side, and the shielding end 12212 is axially extended along the driving portion 121 and is located at the opening of the connection gap 123. This arrangement further enhances the protection capability of the connection gap 123 by adding an additional shielding structure on the circumferential side of the air deflector 1221. Specifically, the shielding end 12212 can effectively prevent water from entering the connection gap 123 from the side, ensuring that even in the case of multi-angle flushing, moisture will not penetrate into the interior of the driving portion 121, thereby greatly reducing electrical short circuits and other potential safety hazards; further, in some embodiments, the shielding end 12212 extends along the circumferential side of the driving portion 121 and tilts toward one side of the driving portion 121, thereby better shielding the connection gap 123.

[0037] Embodiment 5: Further, as Figure 1-10 A washable smoking assembly is shown, wherein the rotating portion 122 is provided with a blade 1222 connected to the air guide cover 1221 , and the cross section of the blade 1222 is an arc-shaped arrangement convex toward the discharge port 112 .

[0038] This embodiment includes the features of the fourth embodiment, and is different from the fourth embodiment in that, in the present invention, the rotating portion 122 is provided with a blade 1222 connected to the guide cover 1221, and the cross section of the blade 1222 is an arc-shaped arrangement convex toward 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 guide extension end 12211, so that the arc-shaped blade 1222 can push the water flow to the side of the discharge port 112 through the arc surface during the rotation process, and form a stable parabolic trajectory. Since the end of the blade 1222 is connected to the guide extension end 12 211, so when the water flow leaves the blade 1222, the water flow has exceeded 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 cross-section of the blade 1222 also helps to reduce the water flow resistance, so that the rotation of the rotating part 122 during the cleaning process is more stable and efficient; further, the blade 1222 is located at the end close to the driving part 121 and is arranged in a wavy shape. Through this arrangement, the water flow will be more disturbed when passing through the wavy end of the blade 1222, thereby generating a stronger turbulent effect, which can more effectively wash away the grease and impurities attached to the inner wall of the discharge component cavity 114.

[0039] Embodiment 6: Further, as Figure 1-10A washable smoking assembly is shown, wherein the blade 1222 is inclined from the guide cover 1221 located near the smoking port 111 to the discharge port 112, and the central axis of the blade 1222 forms an angle β with the central axis of the guide cover 1221, and the angle β ranges from 30° to 60°.

[0040] This embodiment includes the features of the fifth embodiment, and is different from the fifth embodiment in that, in the present invention, the blade 1222 is inclined from the side of the deflector 1221 located near the smoking port 111 to the side near the discharge port 112, and the central axis of the blade 1222 forms an angle β with the central axis of the deflector 1221, and the angle β ranges from 30° to 60°. This setting reasonably adjusts the angle of the blade 1222, so that the water flow can obtain the best guiding and acceleration effect when passing through. Specifically, when the angle β is set at 30°-60°, the blade 1222 can effectively guide the water flow to form a stable parabolic trajectory along the surface of the deflector 1221 during the rotation process, and finally cross the connecting gap 123 and be discharged from the discharge port 112. The setting of this inclination angle not only ensures that the water flow has sufficient power to flow along the surface of the deflector 1221, but also avoids excessive resistance or turbulence, thereby improving the drainage efficiency and cleaning effect. Furthermore, if the angle β is less than 30°, the inclination of the blade 1222 will become relatively gentle, resulting in water When the water flows through the blade 1222, it cannot obtain enough thrust, thereby reducing the speed at which the water flows further into the discharge component cavity 114. When the water flow speed is too low, the risk of the water flowing into the connection gap 123 will increase. In addition, a smaller inclination angle may result in insufficient water flow speed, which may result in the inability of the water flow to fully flush the discharge component cavity 114 and remove the residue in the discharge component cavity 114. Further, if the β angle is greater than 60°, the inclination of the blade 1222 is too large, which may cause the water flow to generate greater resistance and turbulence when passing through the blade, increasing the complexity and instability of the water flow path. In addition, an excessively large inclination angle may cause the water flow to deviate from the predetermined path, and may even cause part of the water flow to directly impact the drive unit 121, increasing the risk of moisture infiltration. At the same time, an excessively large inclination angle may also increase the friction between the blade 1222 and the water flow, thereby reducing the overall durability of the drive component 12, and may increase the noise and vibration of the drive component 12 during operation. Further, in this embodiment, the β angle is 30°.

[0041] Embodiment 7: Further, as Figure 1-10 A washable smoking assembly is shown, wherein the smoking assembly 1 further comprises a filter 19 fixed to the smoking port 111, the filter 19 is detachably connected to the smoking port 111, and the pore size of the filter 19 is 2-4 mm.

[0042] This embodiment includes the features of the sixth embodiment, and is different from the sixth embodiment in that, in the present invention, the smoking assembly 1 also includes a filter 19 fixed to the smoking port 111, and the filter 19 is detachably connected to the smoking port 111. The pore size of the filter 19 is 2 to 4 mm. This setting can effectively intercept large particles of grease and impurities by setting the filter 19 at the smoking port 111 to prevent them from entering the interior of the discharge assembly cavity 114, thereby reducing the amount of grease accumulated in the discharge assembly cavity 114, thereby reducing the frequency and difficulty of cleaning; further, the detachable connection setting of the filter 19 makes it possible to The user can easily disassemble and clean it to ensure that the filter always maintains a good filtering effect; further, by setting the aperture of the filter 19 between 2 and 4 mm, the filter 19 can effectively intercept larger particles without generating excessive resistance to the airflow, thereby ensuring the efficient operation of the smoking component; further, in this embodiment, the aperture of the filter 19 is 2 mm; further, in some embodiments, the filter 19 is fixed to the smoking port 111 by magnetic attraction; further, in some embodiments, the filter 19 is fixed to the smoking port 111 by a snap-fit ​​structure.

[0043] Embodiment 8: Further, as Figure 1-10 A washable smoking assembly is shown, wherein the smoking assembly 1 also 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 to the side of the driving portion 121 away from the rotating portion 122, the diameter of the control assembly connecting end 166 is smaller than the diameter of the driving portion 121, the control assembly connecting end 166 is provided with a protruding snap-fit ​​connecting end, and the driving portion 121 is located in a connecting groove for the snap-fit ​​connecting end to extend into.

[0044] This embodiment includes the features of the seventh embodiment, and is different from the seventh embodiment in that, in the present invention, the driving unit 121 guides the wires to the inside of the control component 16 through the inside of the control component connecting end 166. This arrangement not only optimizes the internal structural layout, but also avoids the contact of the wires with moisture, thereby improving the safety and stability of the electrical connection; further, since the diameter of the control component connecting end 166 is smaller than the diameter of the driving unit 121, this makes the water flow in the direction of the discharge port 112 in a parabolic shape during the process of the water flowing through the deflector 1221 to the discharge port 112, so that the water flows over the connection between the driving unit 121 and the control component connecting end 166, effectively preventing the water from flowing through or directly impacting the connection between the driving unit 121 and the control component connecting end 166; further, through the coordinated use of the snap-fit ​​connecting end and the connecting groove, not only a stable mechanical connection is achieved, but also an effective seal is formed, preventing the water from entering the inside of the control component 16 through the connection between the driving unit 121 and the control component connecting end 166, thereby improving the waterproof performance and service life of the overall device.

[0045] Embodiment 9: Further, as Figure 1-10 A washable smoking assembly is shown, wherein a protruding rotating part step 1211 is provided on the periphery of the driving part 121, and a distance S1 from the shielding end 12212 to the rotating part step 1211 is between 1.5 mm and 2.5 mm.

[0046] This embodiment includes the features of the eighth embodiment, and differs from the eighth embodiment in that, in the present invention, a protruding rotating part step 1211 is provided on the periphery of the driving part 121, 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 connecting gap 123, thereby effectively preventing moisture from entering the driving part 121, thereby improving the waterproof performance of the entire smoking assembly. Specifically, when the distance S1 from the shielding end 12212 to the rotating part step 1211 is set to between 1.5 mm and 2.5 mm, it is ensured that the shielding end 12212 can shield the connection gap 123 as much as possible, and at the same time, the guiding extension end 12211 can guide the water flow toward the discharge port 112, thereby preventing moisture from entering the connection gap 123; further, this setting also enables 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 when the smoking component 1 vibrates, resulting in an increase in the rotation resistance of the rotating part 122, and can effectively slow down the vibration of the smoking component 1 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, increase the noise and vibration during equipment operation, and even cause increased wear of components and shorten the 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 infiltrating 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.

[0047] Embodiment 10: This embodiment includes all the features of embodiments 1 to 9, with the difference that in this embodiment, the angle α of the conical section is 120°, D1 is 1.5 times of D2, the angle β is 60°, the aperture of the filter 19 is 4 mm, and the distance S1 from the shielding end 12212 to the rotating part step 1211 is 2.5 mm.

[0048] Embodiment eleven: This embodiment includes all the features of embodiments one to nine, with the difference that in this embodiment, the angle α of the conical section is 80°, D1 is 1.3 times of D2, the angle β is 45°, the aperture of the filter 19 is 3 mm, and the distance S1 from the shielding end 12212 to the rotating part step 1211 is 2 mm.

[0049] Embodiment 12: Further, the smoking assembly flushing operation mode includes a water-washable smoking assembly, and further includes the following steps: S1: The driving component 12 performs periodic flushing by alternating forward and reverse rotations, wherein the rotation speed of the forward rotation is greater than the rotation speed of the reverse rotation; S2: The driving component 12 switches to forward high-speed rotation to discharge residual water.

[0050] This embodiment includes all the features of the first to eleventh embodiments, and the difference is that the present invention provides a flushing operation mode for the smoking assembly. First, this flushing operation mode guides the water flow to move toward the discharge port 112 through the forward rotation of the rotating part 122. After the water flow has discharged most of the water, it rotates in the reverse direction to flush the discharge assembly cavity 114, thereby achieving the effect of alternating forward and reverse rotations to periodically flush the blades 1222 and the discharge assembly cavity 114, wherein the rotation of the rotating part 122 in the direction of the blade 1222 is forward rotation. In addition, the impact force of the water flow can be used to effectively remove the residue in the cavity, and the forward high-speed rotation further enhances the drainage effect. In this process, the rotation speed of the forward rotation is greater than the rotation speed of the reverse rotation.

[0051] Specifically, first, in the cleaning mode, the discharge component cavity 114 is filled with water, and the motor is rotated forward at 2000 revolutions for 15 seconds. This process will discharge most of the water through the discharge port 112, and then the water supply is stopped and the motor is reversed for 500 revolutions for 15 seconds. The remaining water in the discharge component cavity 114 is used to flush the blades 1222 and the discharge component cavity 114, so as to prevent excessive water from flowing into the connection gap 123 in the guide cover 1221 due to continued water supply when the rotating part 122 is reversed, and the shielding end 12212 can prevent the water from entering the connection gap 123 during the reverse rotation process. Then, the rotating part 122 is rotated forward for 2000 revolutions for 15 seconds, and reversed for 500 revolutions for 15 seconds, and the process lasts for one and a half minutes. This alternating forward and reverse rotation not only utilizes the strong centrifugal force generated by high-speed forward rotation to throw the grease and impurities on the blades 1222 and in the discharge assembly cavity 114 to the side of the discharge port 112 and discharge them, but also changes the direction of the water flow through a relatively low-speed reverse rotation to ensure that the water flow covers all areas in the cavity, avoiding the problem that some corners cannot be effectively cleaned due to the fixed water flow path, and also avoiding the problem of large amounts of water splashing out of the smoking port 111. In this process, since the cross-section of the blades 1222 is an arc-shaped setting that bulges toward the discharge port 112, the guiding effect of the water flow is further enhanced, so that the water flow can form a parabolic trajectory more stably, and finally cross the connection gap 123 and be discharged from the discharge port 112.

[0052] In addition, after one and a half minutes of alternating rotation, the driving assembly 12 switches to a forward high-speed rotation of 3000 rpm for 30 seconds, the main purpose of which is to quickly discharge the residual water in the discharge assembly cavity 114. The strong centrifugal force generated by the high-speed rotation can quickly throw out the remaining water, ensuring that there is no water accumulation in the discharge assembly cavity 114, preventing bacteria growth or metal parts corrosion caused by water retention. At the same time, this high-speed rotation also helps to completely remove stubborn residues attached to the inner wall of the cavity, further improving the cleaning effect.

[0053] In addition, after the entire flushing process is completed, the buzzer will beep once per second in the last 30 seconds, generating an intermittent sound and light prompt signal to inform the user that the cleaning process has been completed. The present invention combines a washable smoking component so that the user does not need to frequently disassemble and manually clean the smoking component, greatly reducing maintenance costs and time consumption. At the same time, since the entire cleaning process is automated, manual operations are also reduced, improving the safety and reliability of the device.

[0054] Embodiment 13: Further, as Figure 1-11 The tabletop range hood shown includes a flushing operation mode for the extraction component.

[0055] This embodiment includes all the features of embodiments one to twelve, the difference being that the present invention applies a washable inhalation component and its flushing operation mode in a desktop range hood. Specifically, a washable inhalation component is integrated in the desktop range hood. By setting components such as the air guide cover 1221 and the blades 1222, it can effectively prevent moisture from entering the drive unit 121, simplify the cleaning process and improve the cleaning effect; further, by combining the flushing operation mode of the inhalation component, the drive component 12 performs periodic flushing with alternating forward and reverse rotations, and finally discharges the residual water by forward high-speed rotation to ensure that there is no residual moisture in the cavity. This setting not only solves the problem of inconvenience in cleaning traditional range hoods, but also effectively improves the safety and durability of the equipment; further, 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 inhalation component 1 will automatically complete a series of flushing steps, and notify the user through sound and light prompts after completion. This setting greatly simplifies the user's operating process, reduces the maintenance workload, and improves the user experience.

[0056] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
