[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below.

[0019] This application discloses a range hood 100 capable of self-cleaning surfaces, such as... Figure 1As shown, it includes a housing 11, a mesh cover 12, an oil cup 13, a heating element 14, and an oil collection component 15. A housing pipe 11 is provided on the upper part of the housing 11, and a through hole is provided on the lower part of the housing 11. A fixing groove formed by an inward indentation is provided on one side of the housing 11. The housing 11 forms the basic frame of the range hood 100. The through hole is used to guide the oil fumes from the lower part of the range hood 100 into the range hood 100, and the housing pipe 11 is used to lead the oil fumes inside the range hood 100 out to the outside. Figure 2 As shown, the mesh cover 12 includes several through holes. The mesh cover 12 is positioned on the through holes of the outer casing 11, below the range hood 100, directly facing the cooking area. The mesh cover 12 is used to capture large particles of oil fumes, preventing these larger grease particles from directly entering the range hood 100, thus protecting the motor and other components inside the range hood 100 from contamination. An oil cup 13 is located at the bottom of the mesh cover 12 to collect the grease trapped by the mesh cover 12, facilitating disassembly and emptying of the grease to ensure the cleanliness and normal operation of the range hood 100. Several heating components 14 are evenly distributed on the mesh cover 12. The heating components 14 heat the grease on the mesh cover 12, causing the grease to fall off the mesh cover 12, thereby cleaning the mesh cover 12. Figure 3As shown, one side of the oil collecting component 15 is provided with a protrusion 151 corresponding to the fixing slot. The oil collecting component 15 is fixed in the fixing slot through the protrusion 151 and is detachably connected to the outer shell 11. The shape of the oil collecting component 15 is an arc shape that gradually concaves inward from both ends. The oil collecting component 15 is used to collect the grease that falls off the heating mesh cover 12 of the heating component 14, preventing grease from splashing and affecting hygiene. In addition, the oil collecting component 15 of this application is fixed in the fixing slot through the protrusion 151 and is detachably connected to the outer shell 11. When the oil collecting component 15 is not in use, it can be directly removed from the outer shell 11. The protrusion 151 on the oil collecting component 15 and the fixing slot form a hook-like form for fixing. Taking the plane level with the through hole of the outer casing 11 as the horizontal plane, the projection of the oil collecting component 15 on the horizontal plane is the oil collecting component 15 projection, and the projection of the mesh cover 12 on the horizontal plane is the mesh cover 12 projection. The width of the oil collecting component 15 projection is greater than the width of the mesh cover 12 projection, and the size of the oil collecting component 15 is greater than the size of the mesh cover 12, so that the oil collecting component 15 can collect all the grease that falls off the mesh cover 12. The distance between the oil collecting component 15 and the mesh cover 12 is the opening for the oil fumes to enter. To prevent the oil collecting component 15 from affecting the entry of oil fumes into the range hood 100, the distance between the end of the oil collecting component 15 away from the outer casing 11 and the mesh cover 12 is greater than or equal to 25cm. In this application, the heating component 14 of the range hood 100 is evenly distributed on the mesh cover 12. By heating, the grease on the mesh cover 12 melts and falls off, reducing the frequency and difficulty of manual cleaning of the mesh cover 12 by the user and improving cleaning efficiency. The oil collection component 15, through the cooperation of the protrusion 151 and the fixing slot, makes it easy to install and disassemble, facilitating regular cleaning by the user. This application, by combining the heating component 14 and the oil collection component 15, achieves an automatic cleaning function for the range hood 100, improving the user experience while maintaining kitchen cleanliness and hygiene.

[0020] As one implementation method, such as Figure 4As shown, the plane containing the slot opening of the fixed slot is taken as the slot plane, and the extension direction of the bottom of the fixed slot is taken as the extension direction of the bottom of the slot. The angle α between the extension direction of the bottom of the slot and the slot plane is greater than or equal to 20° and less than or equal to 50°. The angle between the protrusion 151 and the oil collecting component 15 corresponds to angle α. The angle α between the extension direction of the bottom of the fixed slot and the slot plane is designed to be greater than or equal to 20° and less than or equal to 50°. This angle range is chosen to ensure that the "hook" structure formed by the slot opening and the protrusion 151 can better fix the oil collecting component 15. The angle between the protrusion 151 and the oil collecting component 15 corresponds to angle α, which ensures that the protrusion 151 can fit tightly against the slot opening, forming a stable fixing point. By designing a specific angle, the effects of gravity and friction can be used to make the oil collecting component 15 more stable after installation and less likely to fall off due to external forces such as vibration or collision. The angle design increases the stability of the fixation, but still maintains the detachability of the oil collecting component 15. Users can easily install and remove the oil collection component 15 for convenient daily cleaning and maintenance. This design, by optimizing the angle of the fixing slot and the protrusion 151, not only enhances the fixing effect of the oil collection component 15 and prevents it from falling off during use, but also maintains the convenience of installation and removal, improving the user experience and the reliability of the equipment.

[0021] In one implementation, the plane containing the bottom of the oil collecting component 15 is taken as the oil collecting bottom surface, and the distance between the two ends of the oil collecting component 15 and the oil collecting bottom surface is greater than or equal to 10cm and less than or equal to 15cm. This height range ensures that there is sufficient space inside the oil collecting component 15 to store the grease that falls off the mesh cover 12. This ensures that the oil collecting component 15 will not overflow when collecting a large amount of grease, preventing grease from leaking into the kitchen environment and maintaining the cleanliness and hygiene of the kitchen.

[0022] In one embodiment, a filter screen is provided on the side of the mesh cover 12 near the outer shell 11, the diameter of the through hole of the mesh cover 12 is 1mm to 5mm, and the oil collection part 15 is made of high temperature resistant stainless steel.

[0023] In one implementation, the heating assembly 14 also includes a heating switch and a control unit. Users can remotely and locally control the heating assembly 14 via the heating switch and control unit, respectively. The control unit can be designed as a touchscreen or a physical button, allowing users to intuitively adjust the heating temperature and turn the heating function on / off.

[0024] In one implementation, the protrusion 151 and the interior of the fixing groove are magnetized. Through magnetization, a magnetic force is generated between the protrusion 151 and the interior of the fixing groove, allowing the oil collecting component 15 to be firmly adhered to the fixing groove after installation, greatly enhancing the stability of the fixation. Magnetic adsorption effectively prevents the oil collecting component 15 from loosening or falling off during use due to vibration, collision, or other reasons, ensuring that it remains in the correct position at all times.

[0025] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
