Description

Technical Field

[0001] This utility model relates to a portable exhaust fan, and more specifically, to a portable exhaust fan that is placed on a table to absorb and expel fumes generated during cooking on the table. Background Technology

[0002] In barbecue areas, the smoke from the grill makes the air unpleasant. The smoke also carries oil from the meat, polluting the room and causing odors to seep into the air and onto the people grilling. In particular, the large amount of smoke produced when grilling meat or fish poses a problem: people around the grill are exposed to the smoke, causing odors to seep into their clothes, and the oil residue is also very unpleasant. Therefore, to quickly remove this smoke or ventilate while preserving the flavor of the meat, ventilation systems are installed, primarily by directly connecting the burner to the chimney or by mounting an external chimney above the burner.

[0003] On the other hand, conventional exhaust fans with oil receiving components inside the main body have channels through which oil needs to flow to the main body. The oil remains in the channels, resulting in poor hygiene and making it difficult to manage bacterial growth. Utility Model Content

[0004] This utility model is proposed to solve the problems of the prior art. Its purpose is to provide a portable exhaust fan that can be easily used on a table or as an outdoor portable device to purify the air by inhaling oil components and dust generated during cooking.

[0027] like Figures 1 to 6 As shown, the portable smoke exhaust fan of this utility model includes: a support part 200, which is placed on a table, with an open upper part forming a vertical column, and an oil receiving part 400; a main body part 300, which is formed on the upper part of the support part 200; and an oil receiving part 500, which is detachably connected to the oil receiving part 400.

[0028] The main body 300 is formed with a front cover 310 on one side, an exhaust mask 600 on the other side, and an oil drain guide 370 communicating with the support on the lower part. A filter unit 340 is installed on the front cover 310, and an intake fan 350 and a motor 700 are included inside.

[0029] The motor bracket 701 is fastened to the motor 700, and the suction fan 350 is fastened to the motor bracket 701. The suction fan 350 is rotated by the drive of the motor 700 to exert suction force on the filter unit 340. A motor cover 355 is provided in front of the motor 700 to accommodate the motor 700. A rotating cover 312 is provided in front of the front cover 310, which passes through the front cover and is fastened to the motor cover 355. The rotating cover 312 is fixed to the front cover 310 by fastening a pressure ring 311 in front.

[0030] A filter unit 340 is installed inside the rotating cover 312. To replace the filter unit 340, when the front pressure ring 311 is rotated, the rotating cover 312 rotates along with the pressure ring 311 and separates from the motor cover 355, allowing the filter unit 340 stored in front of the rotating cover 312 to be removed and replaced with a new filter unit 340.

[0031] The front cover 310 is provided with an indicator light 307 to identify whether it is working or not. The indicator light 307 is preferably an LED light. The PCBA 308 can display different colors according to the working stage.

[0032] An exhaust mask 600 is attached to the other side of the main body 300. The exhaust mask 600 is inserted into the rear end of the main body 300 and fastened to the motor cover 355 inside the main body 300. The exhaust mask 600 seals the rear of the main body 300 with an exhaust mask cover 620.

[0033] The exhaust mask 600 has a disc shape with a through hole 660 in the center and multiple exhaust holes 6320 on the edge.

[0034] The intake fan 350 draws in the fumes generated during cooking with appropriate suction force and passes them through the filter unit 340. After filtration, only the purified air is discharged to the outside through the rear mesh 622 of the main body 300.

[0035] Oil adhering to the filter unit 340 can fall and be collected in the oil receiving member 500. The oil receiving member 500 can be disposed at the lower part of the filter unit 340 to collect the fallen oil, and can be easily separated from the oil receiving member joint 400 of the support 200 for cleaning. The oil receiving member 500 is detachably attached to the oil receiving member joint 400 formed in the support 200.

[0036] An oil drain guide 370 is formed on the lower part of the main body 300 and is connected to the upper opening support 200.

[0037] The support portion 200 has an oil receiving part 400. The oil receiving part 500 has a shape corresponding to the oil receiving part 400 and is capable of accommodating oil collected from the filter unit 340; its shape is not limited. A handle 504 is formed on the outside, and it is open at the top. The oil receiving part 400 is recessed in the upper part of the support portion 200 and includes a slot 420 at the lower end for inserting the oil receiving part 500.

[0038] Reference Figure 4 The slot portion 420 includes two vertically formed sidewalls 422 and a flat plate 424 formed horizontally on the upper part of the two sidewalls 422, and a guide rail 426 is formed parallel to the bottom surface of the flat plate 424 on the upper part of the inner circumferential surface of the two sidewalls 422.

[0039] The oil receiving part 500 may have a guide groove 506 formed on its lower surface in such a way as to be inserted into the guide rail 426. Therefore, when the oil receiving part 500 is inserted or removed, it can move smoothly along the guide groove 506 and the guide rail 426.

[0040] On the other hand, the oil receiving component 500 may include an elastic locking piece 530, which is formed on one side of the inner surface of the guide groove 506 in an elastic manner. Therefore, the elastic locking piece 530 adheres to the inner circumferential surface of the guide rail 426 to provide temporary fixing force, so that the oil receiving component 500 will not be accidentally disassembled even if the main body 300 is tilted.

[0041] On the other hand, the front cover 310 internally houses the filter unit 340 and has a connecting boss 330 that attaches to the motor cover 355. An oil drain port 360 passes through the lower part of the connecting boss 330. Therefore, oil falling from the filter unit 340 flows through the oil drain port 360 to the oil drain guide 370 formed on the lower part of the main body 300 and is collected in the oil receiving member 500.

[0042] Since the oil components collected in the filter unit 340 are in a liquid state, the movement distance is minimized by allowing them to fall directly into the oil receiving part 500. This allows for immediate collection in a liquid state, thus solving the hygiene problem caused by the oil solidifying and remaining inside the conveying channel during the specified distance traveled, as was the case previously. Furthermore, the oil receiving part exposed to the outside can be immediately separated and cleaned, making it hygienic and convenient to use.

[0043] On the other hand, the main body 300 includes a guide tube 375, which is connected to the oil outlet 360 in a manner that allows the oil from the filter unit 340 to safely fall into the oil receiving member 500. The guide tube 375 is tubular in shape and extends relatively long towards the oil discharge guide 370. Since the oil captured in the filter unit 340 moves through the oil outlet 360 to the guide tube 375 and falls into the oil discharge guide 370 to be collected in the oil receiving member 500, and the collected oil is removed by separating the oil receiving member 500, cleaning becomes easy.

[0044] Reference Figure 5 The filter unit 340 is composed of layers of hydrophobic oil mesh 341, condensation mesh 342, deodorizing mesh 343, and filter sponge 344, and filters in a way that allows oil or water to be filtered, adsorbed and removed, and only air is discharged.

[0045] Reference Figure 3 The main body 300 has a PCB cover 603 on its upper part, and a switch 630 is provided inside the PCB cover 603. The switch 630 includes a switch ball 605, a slider 601, and a PCBA switch 602. When the switch 630 is pushed to the left or right and rotated in the elongated hole 304, the speed of the intake fan 350 can be adjusted to regulate the exhaust volume by adjusting the working stage of the motor 700.

[0046] Reference Figure 6The support 200 is detachably connected to the bracket 100 at the bottom in a height-adjustable manner.

[0047] The support portion 200 includes an oil receiving component 500 on one side and a battery box 201 for accommodating batteries on the other side.

[0048] The portable smoke exhaust fan of this utility model can be configured to receive power via wired or wireless means, and has a built-in battery 203, thus facilitating wireless use. Alternatively, it can be configured with a wire connection port 440 for wired connection to a power source.

[0049] A main PCBA 202 is located at the rear of the battery compartment 201, and the battery compartment 201 is sealed by the front cover 210. On the other hand, a charging connection portion 205 is formed on the cover 210. An indicator light 204 is provided to indicate the charging status, and the cover 210 is made of a transparent material to indicate that the indicator light 204 is lit, or a transparent portion (not shown) may be provided at the position corresponding to the indicator light 204.

[0050] The bracket 100 can be attached to and detached from the support 200 by magnetic attraction. A protruding insertion protrusion 120 is formed on the top of the bracket 100, and a corresponding insertion groove 425 is formed on the bottom surface of the support 200. A magnet (not shown) can be formed in the insertion protrusion 120, and an iron plate can be formed in the insertion groove by magnetic attraction.

[0051] A shock-absorbing pad 115 may be included between the bracket 100 and the support 200 to reduce noise or vibration.

[0052] On the other hand, the bracket 100 may further include a connection part 105 for wireless charging.

[0053] The bracket 100 includes a bracket cover 110 that can be opened and closed, and can store and store cables or small items in the interior space.

[0054] On the other hand, a ring 800 is provided in the main body 300, and the ring 800 can be held to carry and move.

[0055] Although preferred embodiments have been described, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such modifications and variations fall within the scope of the appended claims.
