[0034] The application scenarios of portable range hoods are very diverse, ranging from outdoor camping with light oil smoke to outdoor barbecue with heavy oil smoke. If the fan only runs at the same speed, there will be energy waste in light oil smoke scenarios, and the problem of not being able to remove oil smoke in time in heavy oil smoke scenarios. Therefore, in order to provide the portable range hood with the function of adjusting the fan speed according to different scenarios and avoid accidentally touching the switch during use, the utility model discloses a portable range hood, wherein, Figure 1 and Figure 3 As shown, the portable range hood includes a body 100, a fan assembly 200, a capacitor controller 300, and a base 400. The body 100 is a hollow tubular structure to form an oil smoke channel inside the body 100; the fan assembly 200 is fixed inside the body 100 to guide the oil smoke through the body 100; the capacitor controller 300 is arranged on the body 100 and is flush with the surface of the body 100. The capacitor controller 300 is electrically connected to the fan assembly 200 to control the switch and speed of the fan assembly; the base 400 is vertically arranged below the body 100 to support the body 100. In this way, the capacitor controller 300 can be used to control the switch of the fan assembly 200 and the gear position of the fan assembly 200 can be adjusted by sliding and touching, thereby controlling the portable range hood to provide different wind speeds for different oil smoke scenes.

[0035] Further, if Figure 2 and Figure 4 As shown, the capacitor controller 300 is a touch button and is set on the top of the body 100. The surface of the touch button is flush with the top surface of the body 100. Placing the capacitor controller 300 on the top of the body 100 facilitates adjusting the working state of the fan assembly at any time during use; and ensuring that each touch button in the capacitor controller 300 is flush with the surface of the body 100 not only ensures the overall design of the range hood, but also avoids accidentally touching the switch during use. Optionally, the capacitor controller 300 includes a touch switch button and a touch slide button to respectively control the switch and gear adjustment of the fan assembly 200.

[0036] Further, if Figure 5 and Figure 7 As shown, the base 400 includes a connecting portion 410, wherein the connecting portion 410 is vertically arranged below the body 100 and fixedly connected to the body 100, and a power supply component 411 is provided inside the connecting portion 410, and the power supply component 411 is electrically connected to the fan assembly 200 and the capacitor controller 300 respectively. Optionally, the base 400 also includes a supporting portion 420, which is arranged below the connecting portion 410 and detachably connected to the connecting portion 410 to encapsulate the power supply component 411 inside the connecting portion 410. Through the cooperation between the supporting portion 420 and the connecting portion 410, the power supply component 411 is fixed in the portable range hood, so that the portable range hood can be freed from the constraints of the power supply and can be used normally in situations where an external power supply cannot be provided, and the application scenarios are more diverse.

[0037] Further, if Figure 8 As shown, the power supply component 411 is a rechargeable battery, so it can be recycled.

[0038] Further, if Figure 2 and Figure 7As shown, the bottom surface of the connecting portion 410 is provided with an opening 412 to facilitate replacement of the power supply assembly 411; the side of the connecting portion 410 is provided with a charging port 413 to charge the power supply assembly 411 via an external power source. In situations where an external power source is provided, the portable range hood can be connected to the external power source via the charging port 413 to reduce the consumption of the power supply assembly 411 and continuously charge the power supply assembly 411. In this way, when it is necessary to continue using the portable range hood in a place without an external power source, the portable range hood can still be used, effectively extending the service life of the portable range hood. Optionally, a switch door 416 is provided at the opening 412, which is pivotally connected to the connecting portion 410 and can rotate in a vertical direction to assist in securing the power supply assembly 411 inside the connecting portion 410. Optionally, a torsion spring is provided at the pivotal connection between the switch door 416 and the connecting portion 410 to ensure that the switch door 416 automatically pops open after the switch door 416 is unlocked, thereby facilitating the user's operation of replacing the power supply assembly 411 .

[0039] Further, if Figure 6 and Figure 7 As shown, the connecting portion 410 and the supporting portion 420 are truncated cone structures with a smaller top and a larger bottom, and the bottom diameter of the connecting portion 410 matches the top diameter of the supporting portion 420. By providing a truncated cone structure, the base 400 formed by the connection of the connecting portion 410 and the supporting portion 420 has an overall truncated cone structure with a smaller top and a larger bottom, thereby providing more stable support and ensuring the stable placement of the portable range hood during use.

[0040] Further, if Figure 6 and Figure 7 As shown, the top surface of the support portion 420 protrudes upward to form a connecting platform 421, and the connecting platform 421 extends horizontally to form a locking protrusion 422; the bottom surface of the connecting portion 410 is recessed upward to form a connecting groove 414, and the inner diameter of the connecting groove 414 matches the outer diameter of the connecting platform 421, thereby ensuring that the connecting platform 421 can be locked into the connecting groove 414. In addition, a slot 415 is provided on the inner wall of the connecting groove 414, which opens toward the latching protrusion 422 and extends circumferentially. The latching slot 415 first opens along the axial direction of the connecting portion 410, turns 90° after opening for a distance, and extends circumferentially along the connecting portion 410, forming an inverted "L"-shaped structure. In this way, after the connecting platform 421 is inserted into the connecting groove 414, the latching protrusion 42 enters the latching slot 415 and the supporting portion 420 is rotated. The latching protrusion 42 then moves and is latched into the structure extending circumferentially of the latching slot 415, thereby cooperating to achieve a clamping connection between the supporting portion 420 and the connecting portion 410.

[0041] Further, if Figure 6 As shown, a ball bearing 423 is provided between the connecting portion 410 and the supporting portion 420 to assist the relative rotation between the connecting portion 410 and the supporting portion 420. During the installation and removal of the supporting portion 420 and the connecting portion 410, it is necessary to rotate the supporting portion 420 to engage the latching protrusion 422 into the latching groove 415, or to disengage the latching protrusion 422 from the latching groove 415. By providing the ball bearing 423 between the supporting portion 420 and the connecting portion 410 to form a bearing-like structure, the friction between the supporting portion 420 and the connecting portion 410 is reduced, which facilitates the installation and removal of the supporting portion 420 and the connecting portion 410. Optionally, a ball bearing groove is provided on the supporting portion 420 to accommodate the ball bearing 423 to prevent the ball bearing 423 from falling off after the supporting portion 420 and the connecting portion 410 are separated.

[0042] Further, if Figure 5 As shown, a counterweight 424 is provided within the support portion 420 to ensure that the base 400 provides stable support for the body 100. By providing the counterweight 424 within the support portion 420, the center of gravity of the entire base 400 is shifted downward, balancing the weight of the body 100 and the connecting portion 410, ensuring that the portable range hood remains stable during use.

[0043] Further, if Figure 1 and Figure 2 As shown, the portable range hood further includes a filter assembly 500, which is detachably connected to the main body 100 and disposed perpendicular to the oil fume passage 110 to absorb pollutants from the oil fume passing through the main body 100. Based on the oil fume guidance provided by the fan assembly 200, the main body 100 forms an air inlet and an air outlet at both ends of the oil fume passage 110. Removable filter assemblies 500 are disposed at each of the air inlet and the air outlet to ensure that the oil fume absorption capacity is matched to different oil fume volumes without affecting the oil fume flow through the portable range hood.

[0044] Specifically, if Figure 3 and Figure 4As shown, the filter assembly 500 includes a first filter assembly 510 disposed at the air outlet position and a second filter assembly 520 disposed at the air inlet position, wherein the first filter assembly 510 is detachably connected to the air outlet of the body 100, and the second filter assembly 520 is detachably connected to the air inlet of the body 100. Optionally, the first filter assembly 510 is magnetically connected to the iron sheet disposed at the air outlet of the body 100 by the magnetic force of a magnet, and the second filter assembly 520 is clamped and connected to the bayonet structure disposed at the air inlet of the body 100 by a snap-fit structure. Furthermore, the filter assembly 500 also includes a third filter assembly 530 disposed between the second filter assembly 520 and the fan assembly 200. Optionally, the first filter assembly 510, the second filter assembly 520, and the third filter assembly 530 are activated carbon filters, stainless steel filters, plasma filters, or filters of other different materials to cope with different oil smoke adsorption scenarios. By providing multiple filter assemblies, the portable range hood of the present invention can be reassembled and disassembled to suit different oil smoke volumes. For example, when the oil smoke volume is low or the amount of adsorbed particulate matter is small, redundant filter assemblies can be removed to make the entire unit lighter. However, when the oil smoke volume is high or the amount of adsorbed particulate matter is high, different filter assemblies can be installed to ensure optimal oil smoke filtration. Furthermore, the filter assemblies 500 are detachably connected to the main body 100, simplifying operation and making it easier for users to use. They can also be disassembled and assembled at any time during operation without affecting normal use.

[0045] Alternatively, as Figure 2 As shown, a handle 120 is pivotally connected to the body 100 , and the handle 120 can rotate around the body 100 to provide a structure that is convenient for users to carry when the portable range hood needs to be moved, making the portable range hood more convenient and easy to use.

[0046] In summary, the utility model discloses a portable range hood, comprising a body, a fan assembly, a capacitor controller and a base. The body is a hollow tubular structure to form an oil smoke channel inside the body; the fan assembly is fixed inside the body to guide the oil smoke through the body; the capacitor controller is arranged on the body and flush with the surface of the body, and the capacitor controller is electrically connected to the fan assembly to control the switch and speed of the fan assembly; the base is vertically arranged below the body to support the body. The utility model controls the switch and speed of the fan assembly in the portable range hood by arranging a capacitor controller flush with the surface of the body, thereby avoiding accidental touching of the switch during use, and at the same time provides the portable range hood with a control function of different wind speed gears, which is convenient for selecting the wind speed according to different oil smoke amounts during use.

[0047] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description.
