[0045] The embodiments of the present application will be described below in combination with Figures 1 to 9 A desktop range hood.

[0046] A desktop range hood, comprising a base 1 and a range hood body 2, the range hood body 2 is arranged on the top of the base 1, and the range hood body 2 is arranged obliquely;

[0047] The range hood body 2 comprises a shell 21, a filter module 22, an air duct 23 and a power module 24, the inner wall of the shell 21 is provided with a partition plate 211, the partition plate 211 divides the internal space of the shell 21 into a front end cavity and a rear end cavity, the front end cavity is used for accommodating the filter module 22, the rear end cavity is used for accommodating the air duct 23, and the power module 24 is located inside the air duct 23;

[0048] The inner wall of the partition plate 211 is inlaid with a magnetic attraction piece, the filter module 22 comprises a filter screen 221 and an insert piece 222, the insert piece 222 is arranged opposite to the magnetic attraction piece, the insert piece 222 and the magnetic attraction piece are magnetically attracted to each other, and the filter screen 221 is used for isolating oil;

[0049] The power module 24 comprises a power assembly 241, an impeller 242, a mounting bracket 243 and a damping piece 244, the output end of the power assembly 241 is fixedly connected with the impeller 242, the rear end of the power assembly 241 is connected with the damping piece 244, the damping piece 244 is connected with the rear end of the mounting bracket 243, the damping piece 244 is used for connecting the mounting bracket 243 and the power assembly 241, the mounting bracket 243 is connected with the air duct 23, and the damping piece 244 is used for absorbing the vibration generated by the power assembly 241.

[0050] The oil fume machine body 2 of the present application is provided with a filter module 22 and a power module 24. The filter module 22 is installed in the front cavity of the shell 21, and the power module 24 is installed in the air duct 23. The shell 21 is provided with a partition plate 211, and the partition plate 211 is provided with a plurality of holes, so as to ensure that the front and rear ends of the oil fume machine body are in communication with the outside. The partition plate 211 is inlaid with a magnetic attraction member, and the filter module 222 is provided with a plug 222. The filter module 22 is placed in the front cavity, and the plug 222 and the magnetic attraction member are attracted to each other, so as to install the filter module 22 in the front cavity of the shell 21.

[0051] The filter module 22 comprises a filter screen 221, which can filter oil fumes and isolate oil in the oil fumes in the filter module 22, so as to reduce the occurrence of solidification of the oil fumes in the air duct 233.

[0052] When the user needs to clean the filter module 22, the user only needs to pull out the filter module 22, so as to separate the filter module 22 from the shell 21, thereby facilitating the user to quickly disassemble and clean the filter module 22. Since the shell 21 and the filter module 22 do not need to be installed by screws, the front end of the shell 21 is provided with a smooth inner wall, thereby reducing the cleaning dead angle of the screw holes in the inner wall of the shell 21, and solving the problem that the user is difficult to clean the grease in the cleaning dead angle of the oil fume machine.

[0053] Moreover, the power assembly 241 is connected with a damping member 244 at the rear end, and the damping member 244 can absorb part of the vibration generated by the power assembly 241. The damping member 244 is connected with the mounting bracket 243, and the power assembly 241 can be mounted on the mounting bracket 243 through the damping member 244. In addition, the mounting bracket 243 is connected with the inner wall of the air duct 23, so as to fix the position of the power assembly 241. Since the power assembly 241 is not directly mounted on the air duct 23, the vibration generated by the power assembly 241 is transmitted to the air duct 23 through the damping member 244 and the mounting bracket 243 as intermediates. At this time, the frequency and amplitude of the vibration are greatly reduced in multiple transmissions, and the noise generated by the vibration is also greatly reduced, thereby solving the problem that the rotation speed of the motor in the traditional oil fume machine is increased, the motor generates intense vibration, and the working noise of the oil fume machine is also increased.

[0054] Therefore, the oil fume machine body 2 of the present application is provided with a filter module 22 and a power module 24. The filter module 22 and the partition plate 211 are magnetically attracted and installed, and the damping member 244 can absorb the noise generated by the power assembly 241, thereby solving the problems of difficult disassembly and large noise of the filter screen 221 in the traditional oil fume machine.

[0055] The filter module 22 further comprises a first mounting frame 223 and a second mounting frame 224, the filter screen 221 is located between the first mounting frame 223 and the second mounting frame 224, and the first mounting frame 223 and the second mounting frame 224 are clamped to each other through a clamping structure;

[0056] The top of the first mounting frame 223 is provided with a limiting portion 2231, and the top of the second mounting frame 224 is provided with a groove 2241, and the limiting portion 2231 and the groove 2241 are clamped to each other;

[0057] The insert piece 222 comprises a horizontal portion 2221 and a vertical portion 2222, the vertical portion 2222 abuts against the partition plate 211, and the limiting portion 2231 is provided with a horizontal limiting groove 22311, and the limiting groove 22311 is fixedly connected with the horizontal portion 2221.

[0058] In order to quickly disassemble the filter module 22 and quickly replace the filter screen 221, a clamping structure is mounted on the first mounting frame 223 and the second mounting frame 224, the clamping structure can quickly connect the first mounting frame 223 and the second mounting frame 224, ensure that the front and back of the filter screen 221 abut against the first mounting frame 223 and the second mounting frame 224 respectively, so that the filter module 22 can be quickly assembled; in addition, the clamping structure can also quickly release the connection relationship between the first mounting frame 223 and the second mounting frame 224, so that the filter module 22 can be quickly disassembled.

[0059] In order to shorten the time of aligning the first mounting frame 223 and the second mounting frame 224, a limiting portion 2231 can be arranged on the top of the first mounting frame 223, and the end of the limiting portion 2231 penetrates out of the first mounting frame 223. Since the top of the second mounting frame 224 is provided with a groove 2241, when assembling the filter module 22, only the groove 2241 of the second mounting frame 224 needs to be aligned with the limiting portion 2231, so that the first mounting frame 223 and the second mounting frame 224 can be quickly positioned, thereby further improving the disassembly and replacement speed of the filter screen 221.

[0060] It should be noted that the limiting portion 2231 is provided with a limiting groove 22311, and the limiting groove 22311 is fixedly connected with the horizontal portion 2221, so that the insert piece 222 can be fixed on the limiting portion 2231. Therefore, when the filter module 22 is placed in the front end cavity of the shell 21, the insert piece 222 and the magnetic attraction member in the partition plate 211 are attracted to each other, so that the filter module 22 can be quickly and detachably installed in the front end cavity of the shell 21.

[0061] The insert piece 222 comprises a horizontal part 2221 and a vertical part 2222. The horizontal part 2221 is fixedly connected with the limiting groove 22311. The vertical part 2222 can increase the contact area between the insert piece 222 and the partition plate 211, so that the magnetic force between the insert piece 222 and the magnetic member is increased, and the filter plate structure can be stably installed in the front end cavity of the shell 21.

[0062] The clamping structure comprises clamping blocks 2232 and buckles 2242. The side wall of the first mounting frame 223 is provided with a plurality of clamping blocks 2232. The side wall of the second mounting frame 224 is provided with a plurality of buckles 2242. The buckle 2242 corresponds to the clamping block 2232. The buckle 2242 and the clamping block 2232 are clamped with each other.

[0063] In the embodiment, a plurality of clamping blocks 2232 are equidistantly arranged on the side wall of the first mounting frame 223 in the circumferential direction. A plurality of buckles 2242 are equidistantly arranged on the side wall of the second mounting frame 224 in the circumferential direction. The plurality of buckles 2242 and the plurality of clamping blocks 2232 form a clamping structure. Therefore, when assembling the filter module 22, the first mounting frame 223, the filter screen 221 and the second mounting frame 224 are placed, and then the second mounting frame 224 is rotated, so that the plurality of buckles 2242 correspond to the plurality of clamping blocks 2232 one by one. The buckle 2242 is rotated, and the assembly of the filter module 22 is completed.

[0064] In addition, when disassembling the filter module 22, the buckle 2242 is only rotated in the opposite direction, so that the buckle 2242 and the clamping block 2232 are separated, and the connection relationship between the first mounting frame 223 and the second mounting frame 224 is released.

[0065] The inner wall of the first mounting frame 223 is provided with a surrounding edge 2233, which abuts against the front side of the filter screen 221.

[0066] The bottom of the first mounting frame 223 is provided with a first oil discharge channel 2234. The input end of the first oil discharge channel 2234 is in communication with the inner cavity of the first mounting frame 223. The bottom of the surrounding edge 2233 is provided with two oppositely arranged arc plates 2235. The gap between the two arc plates 2235 forms a first opening 2236. The first opening 2236 is opposite to the first oil discharge channel 2234.

[0067] The bottom of the shell 21 is provided with a through hole 212. The through hole 212 is used for the first oil discharge channel 2234 to pass out of the shell 21.

[0068] The first mounting frame 223 is provided with a surrounding edge 2233, so that the front side of the filter screen 221 abuts against the first mounting frame 223, thus, the oil fume is isolated at the front side of the filter screen 221, and the first oil discharging flow channel 2234 is formed at the bottom of the first mounting frame 223, so as to ensure that the oil liquid hanging at the front side of the filter screen 221 can flow through the first opening 2236 and the first oil discharging flow channel 2234 in turn under the guidance of the filter screen 221, and then be discharged from the range hood.

[0069] Moreover, the surrounding edge 2233 abuts against the filter screen 221, so that the oil liquid at the edge of the filter screen 221 can flow to the arc plate 2235 under the guidance of the surrounding edge 2233, and then drip from the first opening 2236 into the first oil discharging flow channel 2234.

[0070] In addition, the first oil discharging flow channel 2234 penetrates the housing 21 from the through hole 212, so that the connection relationship between the first oil discharging flow channel 2234 and the through hole 212 can also limit the bottom of the filtering module 22, at this time, the top and bottom of the filtering module 22 are both provided with limiting structures, so as to further ensure that the filtering module 22 can be stably installed in the housing 21.

[0071] The bottom of the second mounting frame 224 is provided with a blocking strip 2243, the blocking strip 2243 abuts against the rear side of the filter screen 221, and the bottom of the blocking strip 2243 is provided with a second opening 2244, the second opening 2244 is connected with the first oil discharging flow channel 2234.

[0072] The oil fume contains not only oil liquid but also water vapor, the volume of the oil liquid is large and difficult to pass through the filter screen 221, so the oil liquid is isolated at the front side of the filter screen 221, while the volume of the water vapor is small and can pass through the filter screen 221 smoothly. After part of the water vapor passes through the filter screen 221, it begins to liquefy, so that a large amount of water droplets are hung at the rear side of the filter screen 221. At this time, the water droplets can flow to the second opening 2244 of the second mounting frame 224 under the guidance of the filter screen 221, and then flow into the first oil discharging flow channel 2234.

[0073] In addition, the water droplets at the edge of the filter screen 221 can flow to the second opening 2244 under the guidance of the blocking strip 2243, and since the second opening 2244 is connected with the first oil discharging flow channel 2234, the water droplets can be discharged from the first oil discharging flow channel 2234 to the outside of the housing 21.

[0074] The front end of the air duct 23 is inwardly contracted, the front end of the air duct 23 forms an inclined surface 231 which expands from front to back, and the end of the inclined surface 231 is provided with a second oil discharging flow channel 232, and the end of the second oil discharging flow channel 232 is connected with the through hole 212.

[0075] The water vapor passes through the filter screen 221 and the partition plate 211 in sequence and drifts in the air duct 23. Since the air duct 23 is provided with a fan blade, the fan blade can throw the water vapor to the inner wall of the air duct 23. At this time, the water droplets can flow into the second oil drainage channel 232 at the bottom under the guidance of the inclined surface 231 and then be discharged from the housing 21.

[0076] It is worth noting that the setting of the inclined surface 231 can ensure that the air inlet of the range hood body 2 is smaller than the front end opening of the air duct 23. Referring to Figure 6 , the diameter of the rear end opening in the air duct 23 is consistent with that of the front end opening, so that the air inlet of the range hood body 2 is smaller than the air outlet, thereby forming a pressure difference and ensuring that the range hood body 2 can suck away a large amount of oil fume.

[0077] The mounting bracket 243 comprises an inner frame 2431, an outer frame 2432 and a support 2433. The inner frame 2431 is connected with the damping member 244. The outer frame 2432 is connected with the inner wall of the air duct 23. The two ends of the support 2433 are connected with the inner frame 2431 and the outer frame 2432 respectively.

[0078] The support 2433 is provided with an arc. The center direction of the support 2433 is opposite to the rotation direction of the impeller 242.

[0079] Since the vibration is transmitted through the medium and through multiple media, the energy will be smaller, so that the frequency and amplitude of the vibration will also be reduced. Therefore, in the embodiment, the vibration generated by the power assembly 241 is transmitted to the damping member 244. The damping member 244 is connected with the inner frame 2431, so that the vibration of the damping member 244 can be transmitted to the inner frame 2431. The inner frame 2431 is connected through the support 2433 and the outer frame 2432. The vibration is transmitted to the air duct 23 in sequence through the support 2433 and the outer frame 2432. At this time, the vibration of the power assembly 241 has been transmitted through multiple media. The frequency and amplitude of the vibration are greatly reduced, thereby achieving the effect of damping.

[0080] The rear end of the power assembly 241 is provided with multiple mounting columns 2411 at equal intervals in the circumferential direction. The mounting columns 2411 correspond to the damping member 244 one by one. The mounting columns 2411 extend into the damping member 244.

[0081] There is a gap between the power assembly 241 and the inner wall of the inner frame 2431.

[0082] The inner wall of the inner frame 2431 is provided with multiple clamping positions 24311 at equal intervals in the circumferential direction. The openings of the multiple clamping positions 24311 all face the center of the inner frame 2431. The clamping positions 24311 are clamped with the damping member 244.

[0083] The rear end of the power assembly 241 is provided with a plurality of mounting columns 2411, and the center of the damping member 244 is provided with a through hole 212, so that the mounting columns 2411 can penetrate into the damping member 244, thereby the damping member 244 can be installed at the rear end of the power assembly 241.

[0084] The clamping positions 24311 are arranged along the inner wall of the inner frame 2431, which can improve the stability of the clamping positions 24311. The number of the clamping positions 24311 in the inner frame 2431 is the same as that of the damping members 244, and a plurality of clamping positions 24311 are arranged on the inner wall of the inner frame 2431. When the damping members 244 are clamped with the clamping positions 24311, the power assembly 241 is installed on the inner frame 2431 through the clamping relationship between the damping members 244 and the clamping positions 24311.

[0085] Since the damping members 244 and the clamping positions 24311 are clamped with each other, the damping members 244 install the power assembly 241 in the inner frame 2431. Therefore, when the motor starts, the vibration of the motor can be transmitted to the damping members 244 through the mounting members, the damping members 244 can transmit the vibration to the inner frame 2431, the inner frame 2431 transmits the vibration to the mounting bracket 243, and the mounting bracket 243 transmits the vibration to the outer frame 2432 and the shell 21. At this time, when the vibration reaches the shell 21, the vibration amplitude and frequency shift generated by the motor have been gradually weakened in the layer-by-layer transmission, thereby achieving the effect of damping.

[0086] It is worth noting that there is a gap between the power assembly 241 and the inner frame 2431. Since part of the vibration generated by the power assembly 241 is transmitted to the damping members 244, and the other part of the vibration energy is transmitted to the air, the vibration is dissipated in the air, thereby improving the damping effect of the present scheme.

[0087] The inner frame 2431 is provided with a plurality of first reinforcing ribs 24312 and second reinforcing ribs 24313. The two ends of the first reinforcing rib 24312 are connected to two adjacent clamping positions 24311, and a plurality of second reinforcing ribs 24313 are respectively diverged from the center of the inner frame 2431 to the first reinforcing rib 24312. The end of the second reinforcing rib 24313 is fixedly connected with the first reinforcing rib 24312.

[0088] The first reinforcing rib 24312 connects two adjacent clamping positions 24311, so that the vibration on the clamping position 24311 can be transmitted to the inner frame 2431 or the first reinforcing rib 24312, thereby reducing the frequency and amplitude of the vibration.

[0089] In addition, the first reinforcing rib 24312 is also fixedly connected with a second reinforcing rib 24313, which can improve the stability of the clamping position 24311 and reduce the risk of breakage of the clamping position 24311 after long-term use. The plurality of second reinforcing ribs 24313 diverge from the center of the inner frame 2431 to the plurality of first reinforcing ribs 24312, and at this time, the vibration on the first reinforcing rib 24312 can be transmitted to the second reinforcing rib 24313, thereby further weakening the vibration generated by the motor.

[0090] The damping member 244 comprises a clamping portion 2441, a first damping portion 2442 and a second damping portion 2443, the front end of the clamping portion 2441 is provided with the first damping portion 2442, the rear end of the clamping portion 2441 is provided with the second damping portion 2443, and the diameters of the first damping portion 2442 and the second damping portion 2443 are greater than that of the clamping portion 2441;

[0091] The front and rear ends of the first damping portion 2442 and the second damping portion 2443 are provided with a plurality of convex points 2444, the front and rear ends of the clamping position 24311 abut against the plurality of convex points 2444, and the rear end of the power assembly 241 abuts against the convex points 2444;

[0092] The side walls of the clamping portion 2441 are provided with a plurality of vertical convex strips 2445, and the inner wall of the clamping position 24311 abuts against the convex strips 2445.

[0093] The vibration generated by the power assembly 241 is transmitted to the first damping portion 2442, the clamping portion 2441 and the second damping portion 2443 through the mounting column 2411, so that the vibration can be uniformly distributed on the damping member 244.

[0094] The front end side wall of the clamping position 24311 abuts against the first damping portion 2442, the rear end side wall of the clamping position 24311 abuts against the second damping portion 2443, and the inner wall of the clamping position 24311 abuts against the clamping portion 2441, so that the vibration on the damping member 244 can be transmitted to the clamping position 24311, and the damping member 244 can be stably clamped with the clamping position 24311, ensuring that the power assembly 241 can be installed on the inner frame 2431.

[0095] The damping member 244 is provided with a plurality of convex points 2444 and convex strips 2445, the clamping sites 24311 are respectively in abutment with the plurality of convex points 2444 and the plurality of convex strips 2445, the contact area between the damping member 244 and the clamping sites 24311 is small, only a part of the vibration energy of the damping member 244 can be transmitted to the clamping sites 24311 through the convex points 2444 and the convex strips 2445, in addition, the vibration energy of another part of the damping member 244 is transmitted to the air, so that the vibration is dissipated in the air, thereby improving the damping effect of the damping member 244.
