[0048] Please refer to Figure 1-3 This utility model proposes a portable range hood, including an oil filter 1, a housing module 2, a fan blade 3, a motor module 4, a base 5, and a guide plate 6. The housing module 2 is a hollow column with one end open as an air inlet 21 and the other end as an air outlet 22. The air inlet 21 of the housing module 2 is provided with a protective net 23. An oil filter slot 24 is provided on the outside of the protective net 23. The oil filter 1 is detachably installed in the oil filter slot 24. A layer of filter cotton (not shown in the figure) can also be added between the oil filter 1 and the protective net 23 to filter odors in the oil fumes.

[0049] In addition, please refer to Figure 5 An oil collection groove 25 is further provided on the inner peripheral wall outside the oil filter screen 1 at the air inlet 21. An oil cup 7 is provided below the air inlet 21, and an oil outlet 26 is provided on the inner wall. The position of the oil outlet 26 corresponds to that of the oil cup 7, and the oil outlet 26 is connected to the oil cup 7. The oil sludge intercepted by the oil filter screen 1 can flow through the oil collection groove 25 to the oil outlet 26, and the oil sludge is collected into the oil cup 7 through the oil outlet 26. The oil cup 7 can be removed from the shell lifting module 2 for cleaning.

[0050] Please refer to Figure 4-6 The fan blade 3 is installed on the motor module 4, and the motor module 4 drives the fan blade 3 to rotate. Furthermore, the fan blade 3 can be removed from the motor module 4 as needed. The motor module 4 is set on the base 5, which includes a motor mounting part 51 and a connecting part 52 surrounding the motor mounting part. The motor module 4 is installed on the motor mounting part 51. The connecting part 52 is provided with a fixing slot 53, which corresponds to the fixing buckle 27 on the inner ring wall of the air outlet end 21 of the housing module 2, so that the base 5 and the main housing module 2 are detachably connected. The base 5 is set at the air outlet end 22 of the housing module 2. After installation, the fan blade 3 will be located inside the housing module 2. A guide plate 6 is set on the other side of the base 5. The guide plate 6 includes an annular guide plate 61. The guide plate 61 has an arc-shaped structure and bends outward from the center of the guide plate 6. A control module 8 is set on the outer side of the guide plate 6. The control module 8 is electrically connected to the motor module 4, thereby controlling the start and speed of the motor module 4, thereby changing the suction power of the range hood.

[0051] Please refer to Figure 1-2 To facilitate the use of this portable range hood in different scenarios, the bottom outer wall of the housing module 2 is provided with a connecting buckle 28 for connecting with an external stand, making it easy to connect with the stand.

[0053] When using this portable range hood, the air inlet 21 is oriented towards the location where oil fumes or smoke are generated. The motor module 4 drives the fan blades 3 to rotate, creating suction that draws the oil fumes or smoke through the oil filter 1 into the housing module 2, and then out through the air outlet 22. Because a guide plate 6 is provided at the air outlet 22, the arc-shaped guide vanes 61 on the guide plate 6 guide the oil fumes or smoke to the rear and surrounding areas. Furthermore, structurally, the base 5 and the housing module 1 are connected by a fixing slot 53 and a fixing buckle 27, facilitating the separation of the base 5 and the housing module 2. When cleaning is required after use, since the guide plate 6 is connected to the base 5, the guide plate 6 can be rotated to disengage the fixing slot 53 of the base 5 from the fixing buckle 27 of the housing module 2. Then, the entire base 5, along with the motor module 4 and the fan blades 3, can be pulled out of the housing module 2 for cleaning. The fan blades 3 can also be separated from the motor module 4 and cleaned separately.

[0054] In addition, it should be noted that in this utility model, a power module (not shown in the figure) can be set between the motor module 4 and the control module 8. The power module can be a rechargeable lithium battery, or it can be directly connected to an external power source through the control module 8.
