In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0045] Combination Figures 1 to 6 As shown, according to a specific embodiment of the utility model, a desktop range hood is provided.

[0046] Specifically, Figure 1 , Figure 2 As shown, the desktop range hood includes: a shell 10, the shell 10 has a accommodating cavity 11; an air inlet hood 20, the air inlet hood 20 is detachably connected to the shell 10, and the external airflow enters the shell 10 through the air inlet hood 20; a fan assembly 30, the fan assembly 30 is located in the accommodating cavity 11, the fan assembly 30 includes a support portion 31 and a plurality of fans 32, a side of the support portion 31 close to the air inlet hood 20 is provided with a plurality of air inlets 311, a side of the support portion 31 away from the air inlet hood 20 is provided with a plurality of air outlets 312, an air duct 313 is formed between each air inlet 311 and each air outlet 312, and each fan 32 is arranged corresponding to an air duct 313.

[0047] In this embodiment, the air inlet hood 20 is detachably connected to the shell 10 to facilitate cleaning and maintenance of the air inlet hood 20. The fan assembly 30 includes a support portion 31 and multiple fans 32, and the support portion 31 is provided with multiple air inlets 311 and multiple corresponding air outlets 312 at intervals to form multiple air ducts 313. The multiple fans 32 and the multiple air ducts 313 are arranged in a one-to-one correspondence, so that a more uniform airflow distribution can be achieved, the air volume can be increased, the air flow resistance can be reduced, the smoking efficiency can be improved, and the air volume adjustment is more flexible.

[0048] Furthermore, a plurality of fans 32 are arranged at intervals along the length direction of the support portion 31 , and the air inlet directions of the fans 32 are arranged in parallel.

[0049] Specifically, by arranging multiple fans 32 at intervals along the length direction, the desktop range hood can effectively utilize the space, and the parallel air inlet direction is conducive to forming a continuous suction effect, thereby improving the overall exhaust efficiency and more effectively removing oil smoke and odor. The fans 32 are arranged in parallel, so that the wind force is evenly distributed in the working area of ​​the desktop range hood, avoiding the situation where the local wind force is too strong or too weak. The design of multiple fans 32 allows the user to choose to turn on some or all fans 32 according to cooking needs, providing more flexible air volume adjustment options to meet the needs of different cooking scenarios. At the same time, each fan 32 can be disassembled and maintained independently, which is convenient for users to clean and replace, and keep the range hood in good working condition.

[0050] like Figure 8 As shown, Figure 8 This is a schematic structural diagram of the first bracket of the desktop range hood of the present application.

[0051] Furthermore, the support portion 31 includes: a first bracket 314, the first bracket 314 is connected to the inner wall of the shell 10, the first bracket 314 is arranged close to the air inlet hood 20, the first bracket 314 is provided with a plurality of spaced installation channels 3141, at least part of the fan 32 is located in the installation channel 3141, a first channel 3142 is formed between the outer peripheral surface of at least part of the fan 32 and the installation channel 3141, and an air inlet 311 is formed at one end of the installation channel 3141 close to the air inlet hood 20.

[0052] Specifically, the first bracket 314 is arranged close to the air inlet cover 20, so that the external airflow can smoothly enter the installation channel 3141, forming an effective air inlet 311. Such a layout helps to guide the airflow to pass through each fan 32 evenly, thereby improving the efficiency of air flow. Multiple spaced installation channels 3141 provide installation positions for the fans 32, and the formation of the first channel 3142 helps the airflow to flow between the fans 32, so that each fan 32 can effectively inhale oil smoke and odor. This helps to improve the air purification efficiency of the desktop range hood and ensure the cleanliness of the kitchen environment.

[0053] like Figure 5 As shown, a convex plate 3143 is provided at one end of the mounting channel 3141 close to the air inlet cover 20, and the convex plate 3143 extends toward the direction of the fan 32 to form an air inlet 311. The size of the air inlet 311 is defined on the convex plate 3143, and the inner diameter of the air inlet side of the first channel 3142 is the inner diameter of the air inlet 311, and the inner diameter of the air outlet side of the first channel 3142 is greater than the inner diameter of the air inlet 311. Therefore, the provision of the convex plate 3143 prevents air from flowing back from the air outlet side to the air inlet side. A plurality of convex bumps 3144 are also provided on the outer side of each mounting channel 3141 on the first bracket 314.

[0054] like Figure 6 , 7 As shown, Figure 6 This is a schematic diagram of the structure of the fan of the desktop range hood of this application. Figure 7 This is a schematic structural diagram of the second bracket of the desktop range hood of the present application.

[0055] Furthermore, the support portion 31 also includes: a second bracket 315, the second bracket 315 is connected to multiple fans 32, the second bracket 315 is connected to the side of the first bracket 314 away from the air inlet cover 20, the second bracket 315 is provided with multiple spaced second channels 3151, and the second channel 3151 forms an air outlet 312 at one end away from the air inlet cover 20.

[0056] Specifically, the second bracket 315 is provided with a plurality of spaced second channels 3151, and the plurality of second channels 3151 are arranged in one-to-one correspondence with the plurality of first channels 3142, and the second channels 3151 are arranged in communication with the first channels 3142, so that the airflow inhaled from the air inlet 311 by the fan 32 in the installation channel 3141 flows through the first channel 3142 to the second channel 3151, and then flows out from the air outlet 312. The air inlet direction of this process is arranged parallel to the air outlet direction, and the path from the first channel 3142 to the second channel 3151 is shorter, thereby reducing the turbulence and resistance of the airflow.

[0057] Each fan 32 includes a fan body 321 and a plurality of convex plates 322, and the convex plates 322 are provided with mounting holes. The inner wall of each second channel 3151 of the second bracket 315 is provided with a plurality of lug columns 3152, and the plurality of lug columns 3152 are arranged one-to-one with the plurality of convex plates 322, and the lug columns 3152 are matched and connected with the mounting holes on the convex plates 322. After the fan 32 is connected to the second bracket 315, it is assembled into the mounting channel in the first bracket 314, and the lug columns 3152 and the convex plates 322 are located in the convex hull 3144, so that the support portion 31 and the plurality of fans 32 are assembled to form a fan assembly 30.

[0058] Furthermore, the air inlet direction of the first channel 3142 is arranged in parallel with the air outlet direction of the second channel 3151. The air inlet and air outlet channels arranged in parallel can make the air flow to each fan in a straight path after entering the desktop range hood, reducing the turbulence and resistance of the air flow, thereby improving the overall air flow guiding efficiency. Since the resistance of the air flow in the parallel channels is small, the power required by the fan can be reduced accordingly, which helps to reduce the energy consumption of the entire system and achieve energy saving and emission reduction.

[0059] Further, the maximum inner diameter of the first channel 3142 is smaller than the minimum inner diameter of the second channel 3151. The smaller inner diameter of the first channel 3142 helps to increase the airflow speed through the channel. When the airflow flows from the first channel 3142 into the second channel 3151, the airflow will expand due to the larger inner diameter of the second channel. Such a design helps to maintain the kinetic energy of the airflow and ensure efficient air flow and the suction of oil smoke. Through the smaller inner diameter of the first channel 3142, a relatively high pressure area can be formed in front of the fan suction port, which helps to improve the suction efficiency of the fan. In the second channel 3151, the airflow expands and the pressure is relatively reduced, which helps to reduce noise and vibration while ensuring smooth discharge of the airflow. In the first channel 3142, the increase in airflow speed helps to reduce energy loss. Although the channel is narrowed, due to the increase in airflow speed, the energy of the fan can be used more effectively and the energy loss in the channel can be reduced.

[0060] like Figure 3As shown, a plurality of air outlet holes 12 are provided on the housing 10, and the air outlet holes 12 are arranged on the side wall opposite to the air inlet cover 20, or the air outlet holes 12 are arranged on the peripheral wall of the housing 10. Distributing the air outlet holes 12 on the side wall or the peripheral wall of the housing helps to achieve uniform distribution of airflow. In this way, the purified air can be discharged evenly, reducing the excessive or weak airflow in local areas, and improving the uniformity and efficiency of air purification. The reasonable layout of the air outlet holes 12 helps to reduce the resistance of the airflow during the discharge process, so that the air can flow out smoothly, thereby improving the working efficiency of the fan and reducing energy consumption. Arranging the air outlet holes 12 on the side wall or the peripheral wall of the housing can enable the desktop range hood to achieve efficient air exchange in a limited space, making the desktop range hood more compact and saving space.

[0061] like Figure 4 As shown, the desktop range hood further includes: a filter assembly 40, which is located in the housing 10 and between the air inlet cover 20 and the fan assembly 30. The position design of the filter assembly 40 enables it to effectively capture and filter the oil fume particles and impurities entering from the air inlet cover 20. Such a layout ensures that the oil fume is greatly reduced before reaching the fan assembly 30, thereby improving the overall oil fume filtering efficiency.

[0062] The filter assembly 40 includes filter cotton 41 and a filter bracket 42 . The filter bracket 42 is connected to the inner wall of the housing 10 , and the filter cotton 41 is connected to the filter bracket 42 .

[0063] Furthermore, the fan 32 is at least one of a centrifugal fan and an axial flow fan, which can provide the technical effects of efficient airflow generation, adaptability to different working environments, compact size design, noise control, and easy maintenance.
