[0045] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0046] Embodiment 1

[0047] Please refer to Figure 1 to Figure 6 The embodiment of the present application discloses a range hood cleaning device, which can be applied to the range hood to achieve the purpose of cleaning the filter in the range hood.

[0048] Specifically, when the range hood is in use, the oil smoke absorbed by the range hood will pass through the filter 100 located inside the range hood, the oil smoke will be filtered by the filter 100, the oil stains in the oil smoke will be adsorbed on the filter 100, and clean gas will be discharged from the range hood, thereby achieving the purpose of filtering the oil smoke.

[0049] like Figure 1 , Figure 3 and Figure 4As shown, the filter screen 100 has a first side 110 and a second side 120, the first side 110 and the preset horizontal plane have a first spacing, the second side 120 and the preset horizontal plane have a second spacing, and the first spacing and the second spacing are different, so that the filter screen 100 is in an inclined state. Specifically, the filter screen 100 can be set to gradually decrease the spacing between the filter screen 100 and the preset horizontal plane during the process of extending from the first side 110 to the second side 120, so that the height of the first side 110 of the filter screen 100 is relatively the highest, and the height of the second side 120 of the filter screen 100 is relatively the lowest. When the filter screen 100 is in an inclined state, the oil smoke sucked into the range hood will move along the mesh surface of the filter screen 100 and pass through the filter screen 100 due to the wall attachment effect, so that the oil smoke can pass through the filter screen 100 evenly from all parts, so that the filter screen 100 has a better oil smoke filtering effect.

[0050] The oil fume cleaning device includes a dropper 200. By injecting cleaning liquid into the dropper 200, the cleaning liquid can be discharged from the dropper 200 in the form of drops and drip onto the filter 100. The cleaning liquid can contact the oil stains on the filter 100 and dissolve the oil stains. The oil stains can pass through the filter 100 with the cleaning liquid, so that the oil stains are separated from the filter 100, thereby achieving the purpose of cleaning the filter 100. The inclined filter 100 allows the cleaning liquid to slide along the mesh surface of the filter 100 after dripping onto the filter 100, so that the cleaning liquid can contact various parts of the mesh surface of the filter 100, thereby increasing the cleaning area. At the same time, the movement of the cleaning liquid along the filter 100 also allows the cleaning liquid to have a longer contact time with the oil stains on the filter 100, so that the cleaning liquid can more fully dissolve the oil stains, thereby achieving the purpose of removing the oil stains.

[0051] Specifically, Figure 1 and Figure 2 As shown, a dripping hole 221 may be provided on the dripping tube 200, and the cleaning liquid is discharged in the form of dripping liquid through the dripping hole 221. In order to allow the cleaning liquid to contact the oil stains on various parts of the filter screen 100, the dripping hole 221 may be arranged opposite to the first side 110 of the filter screen 100, so that the cleaning liquid in the form of dripping liquid may drip onto the first side 110 of the filter screen 100. Since the height of the first side 110 of the filter screen 100 is relatively the highest, the cleaning liquid may move along the mesh surface of the filter screen 100 to the second side 120 of the filter screen 100. The cleaning liquid in the form of dripping liquid may contact the oil stains on various parts between the first side 110 of the filter screen 100 and the second side 120 of the filter screen 100 during the movement process, so that it is not necessary to arrange corresponding cleaning liquid spraying devices on various parts of the filter screen 100, thereby achieving the purpose of saving cleaning liquid.

[0052] When the drip hole 221 is arranged relative to the first side 110 of the filter 100, the opening of the drip hole 221 faces the first side 110 of the filter 100, so that the distance between the drip hole 221 and the first side 110 of the filter 100 is relatively minimum, and the cleaning liquid discharged through the drip hole 221 can directly fall on the first side 110 of the filter 100, so that the cleaning liquid can drip to the first side 110 of the filter 100 at the fastest rate, thereby improving the cleaning efficiency of the range hood.

[0053] Of course, the opening of the drip hole 221 can also be arranged to be offset from the first side 110 of the filter screen 100. For example, the opening of the drip hole 221 can be arranged on the side of the drip tube 200 facing away from the filter screen 100, so that the cleaning liquid discharged from the drip hole 221 can slide along the surface of the drip tube 200 to the bottom of the drip tube 200 and drip onto the first side 110 of the filter screen 100. The specific arrangement position of the drip hole 221 on the drip tube 200 is not limited in this application.

[0054] In the range hood cleaning device, the cleaning liquid can drip onto the first side 110 of the filter screen 100 through the dripping hole 221 on the dripping tube 200. The inclined filter screen 100 can make the cleaning liquid drip onto the first side 110 move along the surface of the filter screen 100, so that the cleaning liquid can contact various parts of the surface of the filter screen 100, thereby removing the oil stains on various parts of the surface of the filter screen 100, so as to save the cleaning liquid. At the same time, when the cleaning liquid moves along the mesh surface of the filter screen 100, the cleaning liquid can be in contact with the filter screen 100 for a longer time, so that the cleaning liquid can more fully dissolve the oil stains, so that the cleaning effect of the range hood cleaning device of the present application is better.

[0055] In some embodiments, such as Figure 3 and Figure 4 As shown, the filter screen 100 also has a third side 130 and a fourth side 140 that are arranged opposite to each other, and the first side 110 and the second side 120 of the filter screen 100 are arranged between the third side 130 and the fourth side 140 of the filter screen 100, and the third side 130 and the fourth side 140 are both connected to the first side 110 and the second side 120. A plurality of drip holes 221 can be provided on the drip tube 200, and the projections formed by the plurality of drip holes 221 on the filter screen 100 are located on the first side 110 of the filter screen 100, and are distributed between the third side 130 and the fourth side 140, so that the drip holes 221 are opposite to each part of the first side 110, and accordingly, the cleaning liquid can cover the entire mesh surface of the filter screen 100 in the process of dripping onto the first side 110 and moving to the second side 120, thereby making all parts of the mesh surface of the filter screen 100 clean.

[0056] Specifically, the axial direction of the dripping tube 200 can be set to extend from the third side 130 of the filter screen 100 to the fourth side 140 of the filter screen 100, and be parallel to the mesh surface of the filter screen 100, and the dripping holes 221 can be set to be distributed along the axial direction of the dripping tube 200, so that the dripping holes 221 are distributed from the third side 130 to the fourth side 140. The spacing between adjacent dripping holes 221 can be set to be smaller, and a larger number of dripping holes 221 are set, so that the cleaning liquid discharged through the dripping holes 221 can be distributed to various parts of the first side 110 of the filter screen 100, preventing the occurrence of a cleaning blind area.

[0057] In order to make the range hood cleaning device have a better cleaning effect, multiple dripping tubes 200 can also be provided, and multiple dripping tubes 200 can be distributed and arranged between the first side 110 of the filter screen 100 and the second side 120 of the filter screen 100. For example, one dripping tube 200 can be arranged opposite to the first side 110 of the filter screen 100, and another dripping tube 200 can be arranged opposite to the middle part between the first side 110 and the second side 120 of the filter screen 100. By providing multiple dripping tubes 200, the discharge amount of the cleaning liquid can be increased, so that the oil stains on the filter screen 100 can be cleaned better.

[0058] In some embodiments, Figure 4 As shown, the filter 100 is provided with a plurality of filter holes 150, and the oil smoke can pass through the filter 100 through the filter holes 150. The oil smoke will contact the filter 100 during the process of passing through the filter holes 150, so that the oil stains are attached to the filter 100. Specifically, the filter 100 can be a plate-like structure, and the filter holes 150 are formed by digging through holes on the plate-like structure. In order to allow the oil smoke to pass through the filter 100 faster, the filter holes 150 can be set as strip holes extending from the first side 110 to the second side 120, so that the filter 100 is grid-shaped. The strip holes have a larger opening area, which can allow the oil smoke to pass through the filter 100 faster. After the range hood has been working for a long time, some oil stains will adhere to the strip holes and block the strip holes, thereby causing the filtering performance of the filter 100 to deteriorate. Therefore, a plurality of drip holes 221 may be provided, and at least some of the drip holes 221 are arranged opposite to the portion of the strip holes on the first side 110, so that the cleaning liquid discharged from some of the drip holes 221 may drip onto the strip holes and move along the length direction of the strip holes, so that the cleaning liquid is in direct contact with the oil stains attached to the strip holes, thereby more fully cleaning the oil stains attached to the strip holes.

[0059] Another part of the drip holes 221 in the plurality of drip holes 221 can be arranged to be opposite to the part of the filter screen 100 where the strip holes are not arranged, so that the drip holes 221 are arranged opposite to each part of the first side 110 of the filter screen 100, and the cleaning liquid dripping on both sides of the strip holes can also move to the strip holes, thereby achieving the purpose of cleaning the oil stains at the strip holes. The number of drip holes 221 can be set according to the size of the filter screen 100, so that the cleaning liquid can cover each part of the filter screen 100.

[0060] In some embodiments, Figure 4 As shown, the range hood cleaning device disclosed in the embodiment of the present application further includes a driving unit 400, which is connected to the filter 100 and can drive the filter 100 to vibrate. After the filter 100 vibrates, the oil stains attached to the filter 100 will also vibrate, so that part of the oil stains attached to the filter 100 can be shaken off, thereby facilitating the cleaning liquid to dissolve and remove the oil stains, and reducing the amount of cleaning liquid used.

[0061] When the cleaning liquid moves along the mesh surface of the filter 100, the vibrating filter 100 can make the cleaning liquid shake on the mesh surface of the filter 100, preventing the cleaning liquid from falling to the filter 100 and directly passing through the filter 100, thereby making the cleaning liquid contact with the filter 100 for a longer time. The cleaning liquid can also impact the oil stains attached to the filter 100 as the filter 100 vibrates, thereby making the cleaning liquid contact with the oil stains on the filter 100 more fully, and the cleaning liquid dissolves the oil stains more efficiently. At the same time, when the cleaning liquid falls into the strip holes, the vibrating filter 100 can make the inner wall of the strip holes fully contact with the cleaning liquid, so that the cleaning liquid can dissolve and remove the oil stains attached to the inner wall of the strip holes. When the cleaning liquid continues to fall to the bottom of the filter 100, the vibrating filter 100 can make the cleaning liquid fully contact with the bottom of the filter 100, so that the cleaning liquid can dissolve and remove the oil stains at the bottom of the filter 100.

[0062] It should also be noted that when the range hood is in operation, the driving unit 400 can also drive the filter 100 to vibrate. After the oil smoke passes through the filter 100, the oil stains will adhere to the filter 100. The vibrating filter 100 can vibrate at least part of the oil stains attached to the filter 100 and separate from the filter 100, thereby reducing the oil stains attached to the filter 100. Accordingly, when cleaning the filter 100, the amount of cleaning liquid can be further reduced, thereby saving the cleaning liquid. At the same time, the vibrating filter 100 can also allow the oil stains to enter the oil box faster, so that the range hood has better oil smoke filtering performance.

[0063] In some embodiments, Figure 4 and Figure 5As shown, the driving unit 400 includes a first linear motor 410. The first linear motor 410 can be arranged on the range hood so that the first linear motor 410 is supported. The first linear motor 410 is also connected to the filter 100. The first linear motor 410 can drive the filter 100 to move back and forth along the driving direction of the first linear motor 410, so that the filter 100 can vibrate. Specifically, the first linear motor 410 can be connected to the first side 110 and the second side 120 of the filter 100. The driving directions of the linear motor connected to the first side 110 of the filter 100 and the first linear motor 410 connected to the second side 120 of the filter 100 are set to the same direction. In this way, the two first linear motors 410 can simultaneously drive the filter 100 to move back and forth along the driving direction of the first linear motor 410, so that the vibration effect of the filter 100 is stronger. At the same time, the first linear motor 410 is arranged on both the first side 110 and the second side 120 of the filter 100 , which can also enable the filter 100 to maintain a stable balance during the vibration process and prevent the filter 100 from deflecting.

[0064] Of course, the first linear motor 410 can also be set on the first side 110 or the second side 120 of the filter 100. When the first linear motor 410 is set on the first side 110 or the second side 120 of the filter 100, an elastic member can be set on the range hood, and the two ends of the elastic member can be connected to the range hood body and the filter 100 respectively. The elastic member can play a role in fixing and supporting the filter 100. At the same time, when the first linear motor 410 drives the filter 100 to reciprocate, the elastic member can be compressed or stretched by the filter 100, and the recovery deformation force of the elastic member can drive the filter 100 to reciprocate faster, so that the filter 100 has a stronger vibration effect.

[0065] Specifically, when the first linear motor 410 is disposed on the first side 110 of the filter 100, the elastic member may be disposed on the second side 120 of the filter 100. When the first linear motor 410 drives the filter 100 to move toward the second side 120, the elastic member is compressed. When the filter 100 moves to the limit position of the second side 120, the elastic member reaches the maximum compression amount. Then, the first linear motor 410 drives the filter 100 to move toward the first side 110. At this time, the restoring deformation force of the compressed elastic member can accelerate the movement of the filter 100 toward the first side 110, thereby making the filter 100 move to the first side 110 faster. Accordingly, when the filter 100 moves toward the first side 110, the elastic member will be stretched as the filter 100 continues to move after the compression deformation is completely restored. After the filter 100 reaches the limit position of the first side 110, it will move toward the second side 120 again. At this time, the restoring deformation force of the stretched elastic member can drive the filter 100 to move toward the second side 120 faster, so that the filter 100 moves to the second side 120 faster. During the reciprocating movement of the filter 100, the elastic member is continuously compressed and stretched, so that the filter 100 always has a higher vibration frequency.

[0066] Of course, multiple elastic members can be provided, and the multiple elastic members can be distributed at various positions of the filter screen 100. For example, elastic members can be provided on the first side 110, the second side 120, the third side 130, and the fourth side 140 of the filter screen 100. At the same time, when the first linear motor 410 is provided on the first side 110 and the second side 120 of the filter screen 100, the elastic member can also be provided on the filter screen 100, so that the filter screen 100 can have a better vibration effect.

[0067] In some embodiments, Figure 4 and Figure 5 As shown, the driving unit 400 mentioned above also includes a second linear motor 420, which can be arranged on the range hood and connected to the third side 130 and the fourth side 140 of the filter 100, so that the second linear motor 420 can drive the filter 100 to move back and forth between the third side 130 and the fourth side 140, so that the filter 100 can vibrate in another direction, so that the filter 100 can have a variety of vibration effects, the cleaning liquid stays on the filter 100 for a longer time, and the cleaning liquid contacts the oil more fully. The second linear motor 420 is arranged on both the third side 130 and the fourth side 140, so that the filter 100 can maintain a stable balance when vibrating in another direction. The second linear motor 420 can also be arranged on the third side 130 or the fourth side 140, and cooperate with the elastic member arranged on the filter 100, so that the filter 100 can also vibrate in another direction. The specific number and position of the second linear motor 420 are not limited in this application.

[0068] Specifically, in the process of driving the filter screen 100 to vibrate by the first linear motor 410 and the second linear motor 420, it can be set that in the first period, the first linear motor 410 first drives the filter screen 100 to reciprocate multiple times between the first side 110 and the second side 120, and then in the second period, the second linear motor 420 drives the filter screen 100 to reciprocate multiple times between the third side 130 and the fourth side 140. Alternatively, it can also be set that after the first linear motor 410 drives the filter screen 100 to complete a reciprocating movement between the first side 110 and the second side 120, the second linear motor 420 drives the filter screen 100 to complete a reciprocating movement between the third side 130 and the fourth side 140. Such a reciprocating cycle can make the filter screen 100 have multiple vibration effects in one cycle, so that the contact between the cleaning liquid and the filter screen 100 is more sufficient.

[0069] In order to make the filter screen 100 reciprocate between the first side 110 and the second side 120, and reciprocate between the third side 130 and the fourth side 140, the first linear motor 410 and the second linear motor 420 may be connected to the filter screen 100 in a hinged manner, or connected to the filter screen 100 through an elastic connection member, so that the filter screen 100 can be offset relative to the first linear motor 410 and the second linear motor 420. Thus, the filter screen 100 has different vibration effects.

[0070] In some embodiments, Figure 3 As shown, the range hood cleaning device also includes a water pump 300, which is connected to the dripping tube 200. The water pump 300 can pump external cleaning liquid into the dripping tube 200 and discharge the cleaning liquid from the dripping hole 221. The water pump 300 can control the flow rate of the cleaning liquid pumped into the dripping tube 200, thereby controlling the flow rate of the cleaning liquid discharged from the dripping hole 221. For example, when the flow rate of the cleaning liquid pumped into the dripping tube 200 by the water pump 300 is large, the frequency of the dripping cleaning liquid discharged through the dripping hole 221 is faster, and when the flow rate of the cleaning liquid pumped into the dripping tube 200 by the water pump 300 is small, the frequency of the dripping cleaning liquid discharged through the dripping hole 221 is slower. In this way, the dripping amount of the cleaning liquid can be controlled according to the condition of the oil stains attached to the filter 100, thereby further saving the cleaning liquid.

[0071] Of course, the water pump 300 can further increase the flow rate of the cleaning liquid pumped into the drip tube 200, so that the cleaning liquid can be sprayed onto the filter 100 through the drip hole 221, so that the cleaning liquid can flush the filter 100 to remove the oil stains firmly attached to the filter 100.

[0072] It is worth noting that in order to control the flow rate of the cleaning liquid, the drip hole 221 can also be set as a variable opening size structure, so that when the discharge amount of the cleaning liquid needs to be increased, it can be achieved by increasing the opening size of the drip hole 221, and when the discharge amount of the cleaning liquid needs to be reduced, it can be achieved by reducing the opening size of the drip hole 221. The drip hole 221 with a variable opening size and the flow-controllable water pump 300 can make the range hood cleaning device disclosed in the embodiment of the present application have more abundant cleaning methods.

[0073] Embodiment 2:

[0074] Based on the range hood cleaning device described above, an embodiment of the present application further discloses a range hood, which includes the range hood cleaning device described above.

[0075] Specifically, Figure 1 to Figure 3 As shown, the range hood includes a housing 500, a filter 100 and a fan 600, wherein the housing 500 can be installed on a wall and is located above the stove, and the housing 500 can provide a mounting base for at least some other components of the range hood. An air inlet 510 is provided on the surface of the housing 500. When the range hood is installed on the wall, the air inlet 510 is arranged opposite to the stove, so that the oil smoke generated at the stove can enter the housing 500 after rising. The fan 600 can be arranged in the housing 500, and the fan 600 is arranged opposite to the air inlet 510. After the fan 600 is started, suction can be generated, thereby further sucking the oil smoke into the housing 500.

[0076] The filter 100 is arranged in the housing 500 and between the air inlet 510 and the fan 600, so that the oil smoke sucked into the housing 500 by the fan 600 is first filtered by the filter 100, thereby achieving the purpose of filtering the oil smoke. The upper side of the housing 500 may also be provided with an air outlet opposite to the fan 600, so that the oil smoke filtered by the filter 100 can be discharged through the air outlet. The filter 100 is arranged obliquely in the housing 500, specifically, the distance between the first side 110 of the filter 100 and the stove is greater than the distance between the second side 120 of the filter 100 and the stove, and the second side 120 of the filter 100 is adjacent to the wall, so that the first side 110 of the filter 100 with a higher height is on the outside, and accordingly, the outside of the housing 500 away from the wall also increases the setting height, thereby preventing the user from bumping against the housing 500 when using the range hood.

[0077] At least part of the dripping tube 200 in the range hood cleaning device described above is disposed in the housing 500, and the dripping hole 221 on the dripping tube 200 is disposed opposite to the first side 110 of the filter 100. The cleaning liquid discharged through the dripping hole 221 can drip to the first side 110 and move along the mesh surface of the filter 100 to the second side 120 to achieve the purpose of cleaning the filter 100. In order to facilitate the collection of the cleaning liquid, a cleaning liquid collecting device can be disposed below the filter 100, so that the cleaning liquid that has dissolved the oil can fall into the cleaning liquid collecting device to prevent the cleaning liquid from contaminating the stove. Specifically, the cleaning liquid collecting device can be a collection box. When cleaning the filter 100, the collection box is placed below the filter 100. After cleaning, the collection box is moved to another position.

[0078] In some embodiments, the water pump 300 in the range hood cleaning device described above may also be disposed on the housing 500, so that the overall structure of the range hood is more compact, and the water pump 300 may also share a power supply system with the range hood, further simplifying the structure of the range hood. The drip tube 200 described above includes a first tube portion 210 and a second tube portion 220, wherein the second tube portion 220 is disposed in the housing 500, a drip hole 221 is provided in the second tube portion 220, and the drip hole 221 on the second tube portion 220 is disposed opposite to the first side 110 of the filter screen 100. Specifically, the second tube portion 220 may be disposed opposite to the first side 110 of the filter screen 100, and the drip holes 221 are distributed along the axial direction of the filter screen 100, so that the cleaning liquid may drip through the drip holes 221 to various parts of the first side 110 of the filter screen 100.

[0079] One side of the first tube 210 is connected to the second tube 220, and the other side of the first tube 210 can extend through the housing 500 to the outside of the housing 500, and the portion of the first tube 210 outside the housing 500 can be arranged to fit the outer wall of the housing 500, and accordingly, the water pump 300 can be arranged on the outer wall of the housing 500 and connected to the first tube 210. In this way, oil smoke can be prevented from contacting the water pump 300 and causing oil stains to adhere to the water pump 300. The portion of the first tube 210 inside the housing 500 can be arranged to be close to the inner wall of the housing 500, so that the first tube 210 can be prevented from occupying too much installation space in the housing 500, so that there is more space in the housing 500 to install other components.

[0080] In some embodiments, the range hood further includes a bracket 520, which can be disposed in the housing 500, and at least part of the drip tube 200 can be mounted on the bracket 520, so that the drip tube 200 is supported. Specifically, a plurality of brackets 520 can be provided, and the plurality of brackets 520 can be distributed and arranged at various parts of the inner wall of the housing 500, and one side of the second pipe part 220 can be connected to the bracket 520, so that the second pipe part 220 is supported. At least part of the first pipe part 210 can also be arranged on the bracket 520. The present application does not limit the specific number and arrangement position of the brackets 520.

[0081] It is worth noting that the range hood cleaning device disclosed in the embodiment of the present application can also be applied to devices having a filter 100 structure, such as air filtering devices.

[0082] In some embodiments, the filter 100 may be a multi-layer structure. For example, the filter 100 may include a first mesh portion 160 and a second mesh portion 170, and the first mesh portion 160 and the second mesh portion 170 are stacked, so that the filter 100 has better oil fume filtering performance.
