[0045] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] like Figures 1 to 7 As shown, the utility model provides a desktop range hood, including a body 1 with a cavity, an air inlet a and an air outlet b are provided on the body 1, and a fan assembly 2 connected to the air inlet a and the air outlet b is provided in the body 1, and the fan assembly 2 is arranged in a volute-shaped air duct in the body 1. The body 1 is preferably made of engineering plastic, and its function is to protect the internal components and to ensure that the wind of the fan assembly 2 can flow smoothly. Figure 4 and Figure 5 As shown. A base 3 is provided at the lower end of the body 1, which can be placed on a table. An air inlet a is provided on one side of the body 1, and an air outlet b is provided at the top of the body 1. An oil filter device I4 is provided at the air inlet a, and an oil filter device II5 is provided at the air outlet b. The oil filter device II5 is detachably connected to the body 1, making it easy to disassemble and replace internal components. Figure 4 As shown, an oil storage box 6 is also provided at the lower portion of the body 1, below the oil filter device I4. This oil storage box 6 is provided with an oil drain port 61. The oil smoke liquid intercepted by the oil filter device I enters the oil storage box 6 and is regularly discharged through the oil drain port 61. The oil filter device I4 and the oil filter device II5 used here are preferably oil suction nets or filter cotton. The oil suction net can be regularly disassembled and cleaned, while the filter cotton needs to be regularly replaced.

[0047] As a further preferred embodiment of the present invention, Figures 4 to 7As shown, a front shell plate 7 is provided at the air inlet a of the fuselage 1. A through hole I71 is formed in the middle of the front shell plate 7. An air inlet pipe 8 connected to the through hole I71 is vertically provided on one side of the front shell plate 7. A hose 9 connected to the through hole I71 is installed on the other side of the front shell plate 7. The front shell plate 7 and the fuselage 1 are detachably fixedly connected. An oil filter device II5 is provided between the hose 9 and the front shell plate 7. An oil leakage port 81 is provided at the bottom of the air inlet pipe 8. The oil storage box 6 is located below the oil leakage port 81. When the fan assembly 2 is in operation, the oil smoke generated on the desktop can be sucked in through the through hole I71 on the front shell plate 7. After two filtrations, it is discharged from the air outlet b on the top of the fuselage 1. The oil enters the oil storage box 6 through the oil leakage port 81 for recovery.

[0048] As a further preferred embodiment of the present invention, a trumpet-shaped air collecting hood 10 is also provided at the inlet end of the hose 9. The hose 9 here is preferably a corrugated tube or a plastic hose, and the tube body can be bent and deformed. The trumpet-shaped air collecting hood 10 is made of metal or plastic. As the air suction port a, the easily bendable hose 9 can make the air suction port a absorb oil smoke at a suitable position, which is easy to operate.

[0049] like Figure 1 and Figure 4 As shown, to facilitate assembly and disassembly, the present invention further includes a stepped hollow cylindrical front cover 20 at the outlet end of the hose 9. The small end of the cylindrical front cover 20 forms a plug-in seal with the hose 9. A snap 1201 is provided on the outer circumferential surface of the large end of the cylindrical front cover 20. A corresponding snap position 172 is provided on the inner side of the through hole 171 of the front shell 7. The snap 1201 and the snap position 172 form a snap connection between the cylindrical front cover 20 and the front shell 7. When the fan assembly 2 is operating, oil smoke enters the hose 9 through the air hood 10 and then, through the cylindrical front cover 20, enters the through hole 171 of the front shell 7, the air inlet pipe 8, and the fuselage 1 in sequence. The oil smoke is intercepted by the oil filter 1, and the liquid oil falls into the oil storage tank 6 through the oil leakage port 81.

[0050] In addition, the present invention also features a support frame 30 at the air outlet b on the top of the fuselage 1. This support frame 30 is equipped with a vent 301, and the oil filter II 4 is mounted at this vent 301. The support frame 30 is a plate-like structure with an opening, preferably made of engineering plastic, mounted on the fuselage 1. Its function is to protect the internal components of the fuselage and to support the oil filter II. Furthermore, a top cover 40, connected to the support frame 3, is mounted above the oil filter II. This top cover 40 features an air outlet grille structure, positioning the oil filter II between the top cover 40 and the support frame 30.

[0051] As a further preferred embodiment of the present invention, an opening c is formed on the other side of the fuselage 1 (i.e., on the side opposite the front shell). A rear shell 50 is mounted at opening c. A through hole II501 is formed in the center of rear shell 50, and multiple snap-in locations II502 are provided on the inner side of through hole II501. A rear cover 60 is also provided at opening c for sealing opening c. Rear cover 60 is provided with snaps II601 that engage with snap-in locations II502. Rear cover 60 is secured to rear shell 50, and then mounted on the other side of the fuselage. Rear cover 60 snaps onto the rear shell 50. It is a circular structure made of engineering plastic, and is provided with snaps II601 and a knob 602. It protects the internal components of the fuselage. After removing rear cover 60, the interior can be cleaned.

[0052] When the tabletop range hood is powered on, the internal fan assembly 2 creates negative pressure, drawing air into the hood. When the tabletop range hood's air intake a faces the fume-laden air, the fume is drawn into the hood along with the air. It first passes through the air hood, then through the hose, oil filter I, the fan assembly, oil filter II, and finally the air outlet b. When the fume-laden air exits the range hood's air outlet, it is filtered out by the filtration device inside the range hood, effectively filtering out the fume.

[0053] The tabletop range hood provided by this utility model has a simple structure and manufacturing process, is easy to install and produce, and has a low manufacturing cost. Furthermore, due to its small size, it does not take up tabletop space and is convenient to use. Furthermore, since the various structural components are easily disassembled and cleaned, regular maintenance is convenient for the user. It extracts fumes generated by hot pots and deep fryers on the tabletop, reducing the disturbance of fumes and odors while significantly improving the comfort of diners during cooking.

[0054] Any matters not described in this utility model are applicable to the prior art.

[0055] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
