Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0041] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] Please see Figure 1 This application provides a desktop range hood 10. Compared to range hoods that are fixedly installed near the kitchen stove, the desktop range hood 10 is smaller in size and more flexible in its use. It can be used on small tabletops such as dining tables in the living room and dining room to absorb the fumes, moisture, and odors generated by cooking utensils such as hot pots and grills on the table.

[0043] The desktop range hood 10 may include at least one range hood body 100, and each range hood body 100 can independently absorb oil fumes, moisture, and odors. The desktop range hood 10 may include one, two, three, or other range hood bodies 100, and users can select a certain number of range hood bodies 100 according to their specific needs.

[0044] It should be noted that when the desktop range hood 10 includes two or more main body 100 units, these main body 100 units can be interconnected to facilitate lifting, transferring, and carrying. Optionally, the two or more main body 100 units can be detachably connected, allowing users to flexibly change the number of main body 100 units according to different usage needs. For example, in scenarios with heavy cooking fumes, a larger number of main body 100 units can be combined; while in scenarios with less cooking fumes, some main body 100 units can be removed, and a smaller number of main body 100 units can be used for fume absorption, thereby reducing usage costs.

[0045] Optionally, the detachable connection method between two adjacent range hood bodies 100 can be arbitrary. For example, two adjacent range hood bodies 100 can be detachably connected by magnetic attraction, threaded connection, snap-fit ​​connection, etc., and this application embodiment does not limit this. When the detachable connection between two adjacent range hood bodies 100 is achieved by magnetic attraction, one range hood body 100 can be provided with a first magnetic attraction element, and the other range hood body 100 can be provided with a second magnetic attraction element, so that the two adjacent range hood bodies 100 can be attracted by the first and second magnetic attraction elements. Optionally, the first magnetic attraction element can be a magnet or an electromagnet, and the second magnetic attraction element can be a magnet or an electromagnet. The electromagnet can be magnetic when energized and non-magnetic when de-energized. Thus, when connection is needed, the electromagnet can be energized to achieve the connection function, and when connection is not needed, the electromagnet can be de-energized and non-magnetic, to prevent the magnetic components of the range hood body 100 from still being magnetic when not connected and attracting other magnetic devices, affecting the use of the desktop range hood 10.

[0046] The magnetic connector can be located either outside or inside the main body 100 of the range hood; this embodiment does not limit this. Preferably, the magnetic connector is located inside the main body 100 of the range hood, so that the appearance of the two range hood bodies 100 connected by magnetic attraction remains intact and more aesthetically pleasing.

[0047] Optionally, when the desktop range hood 10 includes multiple range hood bodies 100, the structures of the multiple range hood bodies 100 can be completely identical, so as to reduce the manufacturing cost of the desktop range hood 10 and facilitate the user to assemble the multiple range hood bodies 100.

[0048] The specific structure of the main body 100 of the range hood will be described below: Please refer to Figures 1 to 3 The main body 100 of the range hood includes a shell 110, a fan 120, and a filter element 130.

[0049] The outer casing 110 has a first receiving cavity 111, a first air inlet 112, and a first air outlet 113, both of which are connected to the first receiving cavity 111. The outer casing 110 is located outside the entire range hood body 100, providing some protection for the components inside. Optionally, the outer casing 110 can be made of a material with high structural strength and good wear resistance to extend the service life of the range hood body 100.

[0050] The impeller 120 is disposed within the first receiving cavity 111 of the outer casing 110, and the impeller 120 is rotatable around the first rotating shaft 121. When the impeller 120 rotates around the first rotating shaft 121, it can draw oil fumes into the first receiving cavity 111 through the first air inlet 112 of the outer casing 110, thereby absorbing the oil fumes. The impeller 120 can be any impeller from related technologies; specifically, the impeller 120 includes multiple blades 122, one end of each blade 122 being positioned close to the first rotating shaft 121, and the other end of each blade 122 extending radially away from the first rotating shaft 121 and offset from the impeller 120, so that when the impeller 120 rotates around the first rotating shaft 121, it can discharge air circumferentially. Optionally, the multiple blades 122 are evenly distributed circumferentially around the first rotating shaft 121 to ensure balanced airflow at all circumferential locations of the impeller 120.

[0051] The filter element 130 is disposed in the first receiving cavity 111 and the air outlet of the impeller 120 faces the filter element 130, so that the oil fumes drawn into the first receiving cavity 111 by the impeller 120 can be filtered by the filter element 130 to remove oil droplets, water vapor and odors, and then discharged from the first air outlet 113 of the outer shell 110, thereby achieving the effect of purifying the air.

[0052] Furthermore, the filter element 130 is arranged around the first rotating shaft 121 on the periphery of the impeller 120, so that the thickness of the main body 100 of the range hood in the direction parallel to the first rotating shaft 121 can be made thinner and the size more compact, making it suitable for living and dining rooms.

[0053] Optionally, the projection of the filter element 130 on the first plane can be located outside the projection of the first air inlet 112 on the first plane, wherein the first plane is perpendicular to the first rotating shaft 121, so as to enhance the concealment of the filter element 130, making it difficult for users to see the stains on the filter element 130, and providing a better user experience.

[0054] Optionally, please refer to Figure 4The outer casing 110 includes a peripheral side plate 114, which is circumferentially disposed around the first rotating shaft 121 on the periphery of the filter element 130. A first air outlet 113 is formed on the peripheral side plate 114. By placing the first air outlet 113 on the peripheral side plate 114 circumferentially disposed around the first rotating shaft 121 on the periphery of the filter element 130, the oil fumes filtered by the filter element 130 can be discharged more quickly through the first air outlet 113 on the peripheral side plate 114, resulting in smoother airflow.

[0055] Optionally, the outer casing 110 further includes two first end plates 115, which are distributed at intervals on opposite sides of the peripheral side plate 114 in a direction parallel to the first rotating shaft 121, and both first end plates 115 are connected to the peripheral side plate 114 to form a first receiving cavity 111, so that the outer casing 110 is generally prismatic or cylindrical in shape, with a simple structure and convenient manufacturing.

[0056] Optionally, one of the two first end plates 115 has a first air inlet 112 formed on it. The first air inlet 112 is located on the first end plate 115 on one side of the peripheral side plate 114. This allows the size of the first air inlet 112 to be larger when the area of ​​the first end plate 115 is designed to be larger, thereby improving the oil fume absorption effect of the range hood body 100. The larger size of the first end plate 115 does not affect the thin design of the range hood body 100 along the direction parallel to the first rotating axis 121.

[0057] Optionally, one of the two first end plates 115 is detachably connected to the peripheral side plate 114, so that components such as the impeller 120 and filter element 130 can be installed inside the peripheral side plate 114 before the first end plate 115 and the peripheral side plate 114 are connected, facilitating the smooth assembly of the range hood body 100. Alternatively, the other first end plate 115 can be integrated with the peripheral side plate 114, reducing the assembly process of the outer casing 110 and improving assembly efficiency. Optionally, one of the two first end plates 115 with a first air inlet 112 can be detachably connected to the peripheral side plate 114, allowing the user to remove the first end plate 115 for cleaning operations such as the first air inlet 112. Optionally, the first end plate 115 and the peripheral side plate 114 can be integrally formed, or they can be connected by welding, bonding, or other methods; this embodiment does not limit this.

[0058] It should be noted that both first end plates 115 can also be detachably connected to the peripheral side plates 114. The peripheral side plates 114 can also include two detachably connected parts distributed along a direction perpendicular to the first rotating shaft 121. One part of the peripheral side plates 114 can be connected to both first end plates 115, and the other part of the peripheral side plates 114 can be detachably connected to both first end plates 115. The structure of the outer shell 110 is not limited in this embodiment.

[0059] Optionally, the main body 100 of the range hood may further include a mesh plate 140 disposed at the first air inlet 112. The mesh plate 140 may have multiple mesh holes 141, the mesh holes 141 being small in size, thereby preventing injury caused by a person inserting their hand into the first receiving cavity 111. Optionally, the edge of the mesh plate 140 may be connected to one of the first end plates 115, and the center of the mesh plate 140 may protrude in a direction away from the first receiving cavity 111, so as to maintain a certain distance from the impeller 120 and other components inside the first receiving cavity 111, and avoid friction.

[0060] Optionally, the first air outlet 113 may include multiple first sub-air outlets 1131, each of which extends along the direction surrounding the first rotating shaft 121, and the multiple first sub-air outlets 1131 may be spaced apart along a direction parallel to the first rotating shaft 121. By providing multiple first sub-air outlets 1131, the size of each first sub-air outlet 1131 can be made relatively small, making it safer to use; at the same time, multiple first sub-air outlets 1131 can increase the exhaust volume of the range hood body 100 and improve the smoke extraction effect. Furthermore, each first sub-air outlet 1131 may include a first structural segment 1132 and a second structural segment 1133 spaced apart along the direction surrounding the first rotating shaft 121, and the first structural segment 1132 and the second structural segment 1133 may be centrally symmetrical about the first rotating shaft 121, improving the aesthetics and exhaust balance of the range hood body 100.

[0061] Optionally, please refer to Figure 5 The filter element 130 may include a housing 131 and a filter element (not shown in the figure). The housing 131 forms a second receiving cavity (not shown in the figure), a second air inlet 1312, and a second air outlet 1313. Both the second air inlet 1312 and the second air outlet 1313 communicate with the second receiving cavity. The filter element is disposed in the second receiving cavity and located between the second air inlet 1312 and the second air outlet 1313. Figure 5 and Figure 6 This allows the oil fumes that enter the first accommodating cavity 111 through the first air inlet 112 under the action of the impeller 120 to enter the second accommodating cavity through the second air inlet 1312 of the filter element 130, and after the oil droplets, water vapor and odors are removed by the filter element in the second accommodating cavity, they are discharged from the main body 100 of the range hood through the second air outlet 1313 and the first air outlet 113.

[0062] It should be noted that the filter element can be made of any material capable of removing oil droplets, water vapor, and odors. For example, the filter element can be made of activated carbon, etc., and this application embodiment does not limit this. Optionally, the filter element can be of any shape. For example, the filter element can be in granular or sheet form, etc., and this application embodiment does not limit this.

[0063] Optionally, please refer to [the relevant document / reference]. Figure 4 and Figure 5 The housing 131 of the filter element 130 may include an inner peripheral plate 1314, an outer peripheral plate 1315, and two second end plates 1316. The inner peripheral plate 1314 is arranged around the first rotating shaft 121 around the periphery of the impeller 120, and the outer peripheral plate 1315 is arranged around the first rotating shaft 121 around the periphery of the inner peripheral plate 1314. The two second end plates 1316 are distributed at intervals on opposite sides of the inner peripheral plate 1314 in a direction parallel to the first rotating shaft 121, and both second end plates 1316 are connected to the inner peripheral plate 1314 and the outer peripheral plate 1315 to form a second receiving cavity. The filter element 130 has a generally annular structure, which is simple in structure and convenient to manufacture.

[0064] Optionally, a second air inlet 1312 may be formed on the inner peripheral plate 1314, and a second air outlet 1313 may be formed on the outer peripheral plate 1315, so that the second air inlet 1312 and the second air outlet 1313 are arranged opposite to each other, and the airflow is smoother.

[0065] Optionally, the second air inlet 1312 and the second air outlet 1313 are offset to prevent the filter element in the second receiving cavity from leaking out. The offsetting arrangement of the second air inlet 1312 and the second air outlet 1313 can be as follows: within an annular surface with the first rotating shaft 121 as the central axis, at least a portion of the first projection of the boundary line of the first air inlet 112 along the radial direction of the annular surface and the second projection of the boundary line of the second air inlet 1312 along the radial direction of the annular surface are offset from each other. Optionally, the at least partial offset between the first and second projections includes: the first projection being entirely offset from the second projection; or, the first projection partially coinciding with and partially offset from the second projection. This embodiment of the application does not limit this to a specific configuration.

[0066] Optionally, the second air inlet 1312 may include a plurality of spaced-apart second sub-air inlets 1317, and the second air outlet 1313 may include a plurality of spaced-apart second sub-air outlets 1318. Further optionally, each second sub-air inlet 1317 may extend in a direction parallel to the first rotating shaft 121, and the plurality of second sub-air inlets 1317 may be spaced-apart in a direction surrounding the first rotating shaft 121. Optionally, each second sub-air outlet 1318 may extend in a direction surrounding the first rotating shaft 121, and the plurality of second sub-air outlets 1318 may be spaced-apart in a direction parallel to the first rotating shaft 121. This allows the second sub-air inlets 1317 and second sub-air outlets 1318 to be made relatively small, resulting in safer use.

[0067] It should be noted that the multiple second sub-intake ports 1317 can also be distributed in an alternating manner to form a mesh structure; the multiple second sub-outtake ports 1318 can also be distributed in an alternating manner to form a mesh structure, and this application embodiment does not limit this.

[0068] Optionally, after the filter element 130 is installed in the first receiving cavity 111 of the housing 110, it can be detachably connected to the housing 110 to facilitate the assembly and disassembly of the filter element 130 and the housing 110. The detachable connection between the filter element 130 and the housing 110 can be arbitrary. For example, the filter element 130 and the housing 110 can be detachably connected by magnetic attraction, threaded connection, snap-fit ​​connection, etc., and this embodiment does not limit this. When the filter element 130 and the housing 110 are detachably connected by snap-fit, one of the filter element 130 and the housing 110 can be provided with a snap-fit ​​element 150, and the other can be provided with a fastening element 160, with the snap-fit ​​element 150 and the fastening element 160 being detachably connected. This application embodiment shows a case where the filter element 130 is provided with a locking member 150 and the outer shell 110 is provided with a fastening member 160. More specifically, the locking member 150 on the filter element 130 includes an insert 151 extending in a direction parallel to the first rotating shaft 121, and the fastening member 160 on the outer shell 110 includes two opposing clamping plates 161, and a slot 162 extending in a direction parallel to the first rotating shaft 121 is formed between the two clamping plates 161, and the insert 151 is engaged in the slot 162.

[0069] Optionally, along the direction in which the insert 151 is inserted into the slot 162, the distance between two adjacent clamps 161 can be gradually reduced to facilitate the smooth insertion and removal of the insert 151 within the slot 162.

[0070] Optionally, the number of locking components 150 can be one or more, and the number of fastening components 160 can be equal to the number of locking components 150, so that each locking component 150 can be connected to a corresponding fastening component 160. When there are multiple locking components 150, the multiple locking components 150 can be evenly distributed along the direction surrounding the first rotating shaft 121 to improve the stability of the filter element 130 and the housing 110 at various positions after installation. Figure 3 In this embodiment of the application, four snap fasteners 150 and four fasteners 160 are shown.

[0071] It should be noted that you should refer to [link / reference]. Figure 4When the first air outlet 113 includes a plurality of first sub-air outlets 1131 spaced apart along a direction parallel to the first rotating shaft 121, one of the engaging member 150 and the fastening member 160 mounted on the housing 110 can be disposed between two adjacent first sub-air outlets 1131 and connected to the housing 110 to avoid obstructing the exhaust of the range hood body 100. Similarly, when the second air outlet 1313 includes a plurality of second sub-air outlets 1318 spaced apart along a direction parallel to the first rotating shaft 121, one of the engaging member 150 and the fastening member 160 mounted on the filter 130 can be disposed between two adjacent second sub-air outlets 1318 and connected to the housing 131 of the filter 130 to avoid obstructing the exhaust of the filter 130.

[0072] Optionally, a portion of the outer casing 110 may protrude in a direction away from the first pivot 121 to form a handle 116. Users can carry the main body 100 of the range hood by gripping the handle 116, achieving a portable design for the desktop range hood 10. Optionally, when the outer casing 110 includes a peripheral side plate 114 and two first end plates 115, only a portion of the peripheral side plate 114 may protrude in a direction away from the first pivot 121 to form the handle 116, or both portions of the peripheral side plate 114 and the two first end plates 115 may protrude in a direction away from the first pivot 121 to jointly form the handle 116. This embodiment of the application does not limit this approach.

[0073] Optionally, when the desktop range hood 10 includes two or more range hood bodies 100, the handles 116 of two adjacent range hood bodies 100 can be joined together to increase the user's grip area and facilitate the taking and placing of the desktop range hood 10. Optionally, when two adjacent range hood bodies 100 are connected by magnetic attraction, the magnetic components of the two adjacent range hood bodies 100 can be installed inside the handle 116 to improve the space utilization of the handle 116.

[0074] It should be noted that when the desktop range hood 10 includes two or more range hood bodies 100, please refer to [the relevant documentation / reference]. Figure 7 In two adjacent range hood bodies 100, at least one of the handles 116 of the range hood body 100 may be positioned with its back to the other range hood body 100. This application embodiment does not limit this.

[0075] Optionally, the peripheral surface of the outer casing 110 surrounding the first pivot 121 may include a planar region 1141, so that the range hood body 100 can be stably placed on a table via the planar region 1141. Alternatively, the planar region 1141 can enable adjacent range hood bodies 100 to be interconnected at the planar region 1141, making the connection more convenient and reliable.
