[0026] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments. [[ID=2�]]

[0027] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figure 1 shown, the present utility model provides a household range hood, including a housing assembly 10 and a filter assembly 20 fixedly installed on the housing assembly 10. The housing assembly 10 is used to be installed in the kitchen and close to the cooking range. When a large amount of oil fume is generated by using the cooking range, the generated oil fume, odor and heat can be discharged through the housing assembly 10 to keep the kitchen environment clean and comfortable. At the same time, the filter assembly 20 is used to block and filter the oil fume grease.

[0029] As Figure 1 - Figure 3As shown, the housing assembly 10 includes a housing body 11 for concentrating cooking fumes. A top shell 12 is fixedly installed on the housing body 11. An air suction fan 13 is fixedly installed inside the top shell 12. An air outlet 14 is provided at the air outlet end of the top shell 12 close to the air suction fan 13. The air outlet 14 can be connected to an external hose that extends outdoors. After the air suction fan 13 is turned on, the suction end of the air suction fan 13 will suck in the cooking fumes dispersed in the kitchen and draw them into the air outlet end along the suction end of the air suction fan 13. Then, the cooking fumes will be discharged outdoors through the external hose connected to the air outlet 14.

[0030] The filter assembly 20 includes a filter plate 21. The filter assembly 20 is fixedly clamped on the housing body 11. The filter plate 21 is inclined on the housing body 11. When the filter plate 21 is inclined, when the cooking fumes come into contact with the filter plate 21, they will flow downward naturally due to the action of gravity. This setting enables the oil and particles in the cooking fumes to be more effectively deposited on the surface of the filter plate 21 instead of directly entering the internal components of the range hood, thereby reducing the cleaning difficulty and the maintenance requirements of the range hood.

[0031] An oil collection box 22 is clamped at the bottom of the housing body 11 and is aligned with the filter plate 21. After the filter plate 21 accumulates oil continuously, due to gravity, the oil will gradually flow into the interior of the oil collection box 22 along the filter plate 21. Thus, the oil can be centrally collected by the oil collection box 22. The oil collection box 22 is clamped at the bottom of the housing body 11, so the oil collection box 22 can be removed when the filter plate 21 is removed, and then the oil inside the oil collection box 22 can be centrally cleaned.

[0032] As Figure 4 and Figure 5 shown, a scraper 26 is slidably connected to the inner wall of the filter plate 21 and is in contact with the inner wall of the filter plate 21. The end of the scraper 26 is serrated. When the scraper 26 moves on the inner wall of the filter plate 21, the oil accumulated on the inner wall of the filter plate 21 can be scraped, so that the oil on the filter plate 21 can be cleaned.

[0033] One side of the filter plate 21 is provided with a handlebar 28. One end of the handlebar 28 extends out of the outer shell 11. The other end of the handlebar 28 is provided with a threaded rod 23. One ends of the handlebar 28 and the threaded rod 23 close to each other are fixedly installed with bevel gears 29 that mesh with each other. A limit groove 24 is formed on one side of the filter plate 21. At the same time, a limit block 25 is fixedly installed on one side of the scraper 26 close to the threaded rod 23, and the limit block 25 extends out of the limit groove 24 and is threadedly connected to the threaded rod 23. Thus, the handlebar 28 can be rotated to drive the threaded rod 23 to rotate through the meshing bevel gears 29. At this time, the limit block 25 will adjust its position on the outside of the threaded rod 23. When the limit block 25 is continuously adjusted downward, the limit block 25 will drive the scraper 26 to move on the inner wall of the filter plate 21. The limit groove 24 can limit the scraper 26. Thus, the grease on the inner wall of the filter plate 21 can be scraped and cleaned by the scraper 26, thereby avoiding manual operation on the scraper 26 and improving the use effect of the scraper 26.

[0034] Sealing blocks 27 are arranged on the outside of the two bevel gears 29. The sealing blocks 27 are used to seal the two bevel gears 29, so as to protect the bevel gears 29, prevent the bevel gears 29 from contacting external oil fumes, and prevent the oil fumes from causing jamming to the bevel gears 29.

[0035] A fixing clip 210 is fixedly installed on the inner wall of the outer shell 11. The inside of the fixing clip 210 has a protruding part, and the fixing clip 210 has a certain toughness. A fixing block 211 is fixedly installed on the filter plate 21 close to the fixing clip 210. At the same time, the top of the filter plate 21 is hinged to the outer shell 11. The fixing block 211 can be close to the inside of the fixing clip 210. Due to the toughness of the fixing clip 210, the fixing block 211 can be clamped inside the fixing clip 210 and blocked by the protruding part. Thus, the filter plate 21 can be fixed through the cooperation between the fixing block 211 and the fixing clip 210. Furthermore, the filter plate 21 can be fixedly installed on the outer shell 11. At the same time, the filter plate 21 can be pulled outwards so that the fixing block 211 disengages from the inside of the fixing clip 210. Thus, the filter plate 21 can be flipped on the outer shell 11, which is convenient for cleaning the filter plate 21 later.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
