Description

Technical Field

[0001] This utility model relates to the field of intelligent range hoods, specifically a hot air intelligent range hood. Background Technology

[0002] Current range hood technology primarily relies on two methods: mechanical filtration and electrostatic adsorption. Mechanical filtration uses multiple layers of filters to intercept oil fume particles, but it is prone to clogging and requires frequent cleaning. Electrostatic adsorption uses a high-voltage electric field to capture particles, offering higher efficiency but raising ozone emission concerns. In recent years, some manufacturers have attempted to introduce auxiliary heating technology to improve the flow of oil fumes, but these generally suffer from high energy consumption and poor temperature control accuracy. With the development of smart homes, the market demand for range hoods that combine high-efficiency purification with energy-saving features is growing rapidly.

[0003] Research indicates that existing range hoods, due to the fixed height of the exhaust duct, are ill-suited for stovetops of varying heights, resulting in poor smoke extraction for both lower and higher stovetops. Furthermore, during smoke extraction, large amounts of oily fumes can form grease droplets that accumulate at the bottom of the exhaust head. Over time, these grease droplets can fall and contaminate the stovetop. Additionally, when disassembling the exhaust head for cleaning, most exhaust heads are secured with screws, which can become slippery under prolonged exposure to oily fumes, increasing the difficulty of disassembly.

[0004] Therefore, those skilled in the art have provided a hot air intelligent range hood to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this application provides a hot air intelligent range hood that solves the problems of the smoke extraction head not being able to guarantee the smoke extraction quality for stoves of different heights, the smoke extraction head being difficult to disassemble, and the oil droplets accumulating at the bottom of the smoke extraction head easily contaminating the stove.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A hot air intelligent range hood includes a main body, a gathering box fixedly connected to the top of one side of the main body, a flexible ventilation pipe connected to one side of the gathering box, the flexible ventilation pipe being made of tin foil, a power supply fixedly connected to the top of one side of the main body, a smoke extraction platform slidably connected to the middle of the inner wall of the main body, and a base plate provided at the bottom of the smoke extraction platform.

[0010] Through the above technical solution, the gears, first rack, and second rack are designed to ensure more thorough extraction of fumes. This allows for precise adjustment of the height of the fume extraction platform, thus enabling fume extraction from stovetops at different heights. The design of the fume extraction head and tray prevents fumes from condensing into oil droplets that fall onto the stovetop below. This makes disassembling and cleaning the fume extraction head more convenient and quick, and also prevents condensed oil droplets from falling onto the stovetop.

[0011] Furthermore, an exhaust fan is fixedly connected to the top of the smoke extraction stand, and the power supply side is electrically connected to the exhaust fan via an electric wire. The top of the smoke extraction stand is connected to one end of a soft-walled ventilation duct.

[0012] The above technical solution allows for the unified collection of oil fumes, making cleaning easier and ensuring that the device emits no odor after the fumes are removed.

[0013] Furthermore, a gear is rotatably connected to the middle of one side of the inner wall of the main body, a first rack is slidably connected to one side of the inner wall of the main body, one end of the first rack is fixedly connected to one side of the smoke extraction table, and a second rack is slidably connected to one side of the inner wall of the main body. The gear meshes with the first rack and the second rack simultaneously.

[0014] The above technical solution provides mechanical power to change the height of the smoke nozzle. The method of changing the height is simple, efficient and easy to operate, thus adapting to stoves of various heights.

[0015] Furthermore, a fixing block is fixedly connected to the middle of one side of the second rack, and a through rectangular notch is opened on one side of the main body, through which the fixing block is placed and extends to the outside of the main body. A cylinder is rotatably connected to the middle of the fixing block, and an insert plate is fixedly connected to one end of the cylinder.

[0016] Furthermore, the insert plate is C-shaped, and two side plates are fixedly connected to one side of the outer wall of the main body. Multiple slots arranged in a linear array are opened on one side of the two side plates, and the two ends of the insert plate correspond to the slots on one side of the two side plates respectively.

[0017] Through the above technical solution, the position of the second rack can be pulled during use, thereby changing the height of the smoke extraction platform. This allows the smoke extraction platform to extract fumes more precisely, resulting in more thorough extraction and enhanced smoke extraction effect of the range hood.

[0018] Furthermore, the bottom surface of the base plate has four grooves arranged in a rectangular array at its four corners. A cigarette holder is fixedly connected to the center of the base plate. The cigarette holder is conical in shape and has multiple through slots on its outer wall. A first threaded rod is rotatably connected to the center of the bottom surface of the cigarette holder. An internal threaded groove is opened in the center of the bottom surface of the cigarette holder, and the first threaded rod is rotatably connected to the internal threaded groove.

[0019] The above technical solution clamps and fixes the base plate and the cigarette butt, preventing oil from slipping the screws, making it easy to disassemble the base plate and the cigarette butt, and providing a good clamping effect.

[0020] Furthermore, a tray is fixedly connected to the bottom end of the first threaded rod, the diameter of which is larger than the diameter of the largest surface of the cigarette butt, and a plurality of second threaded rods arranged in a rectangular array are rotatably connected to the lower surface of the main body.

[0021] Furthermore, the lower surface of the main body has multiple internal threaded grooves arranged in a rectangular array, and the second threaded rods mesh with the internal threaded grooves. The bottom ends of the multiple second threaded rods are fixedly connected with inserts. The inserts are L-shaped and correspond to the grooves arranged in a rectangular array on the bottom of the base plate.

[0022] The above technical solution protects the bottom of the smoke extractor, preventing oil fumes from condensing into oil droplets and dripping onto the stove below.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific implementation method 1:

[0036] Please see Figure 1 , Figure 2 , Figure 4This embodiment of a hot air intelligent range hood includes a main body 1. A collection box 2 is fixedly connected to the top of one side of the main body 1. A flexible ventilation pipe 3, made of tin foil, is connected to one side of the collection box 2. A power supply 4 is fixedly connected to the top of one side of the main body 1. A smoke extraction platform 5 is slidably connected to the middle of the inner wall of the main body 1. A base plate 14 is provided at the bottom of the smoke extraction platform 5. A gear 7 is rotatably connected to the middle of one side of the inner wall of the main body 1. A first rack 8 is slidably connected to one side of the inner wall of the main body 1. One end of the first rack 8 is fixedly connected to one side of the smoke extraction platform 5. A second rack 9 is slidably connected to one side of the inner wall of the main body 1. Wheel 7 meshes with the first rack 8 and the second rack 9 simultaneously. A fixing block 10 is fixedly connected to the middle of one side of the second rack 9. A rectangular notch is opened through one side of the main body 1, and the fixing block 10 is placed in the notch and extends through to the outside of the main body 1. A cylinder 11 is rotatably connected to the middle of the fixing block 10. A strip plate 12 is fixedly connected to one end of the cylinder 11. The strip plate 12 is C-shaped. Two side plates 13 are fixedly connected to one side of the outer wall of the main body 1. Multiple slots are opened on one side of the two side plates 13 in a linear array. The two ends of the strip plate 12 correspond to the slots on one side of the two side plates 13 respectively.

[0037] In this embodiment, a hot air intelligent range hood is described. It should be noted that, through the arrangement of gear 7, first rack 8, and second rack 9, the position of the second rack 9 can be pulled during use, thereby changing the height of the smoke extraction platform 5. This allows the smoke extraction platform 5 to extract fumes more precisely, resulting in more thorough fume removal. This enhances the range hood's fume extraction effect, significantly improving fume extraction efficiency. The ability to precisely adjust the height of the smoke extraction platform 5 allows for fume extraction from stovetops of different heights.

[0038] The working principle of the above embodiment is as follows: First, when it is necessary to extract smoke from the stove, the insert plate 12 is pulled back to disengage it from the groove of the side plate 13. Then, the insert plate 12 is rotated 90 degrees clockwise or counterclockwise, thereby pulling the fixing block 10 up and down. During the movement of the fixing block 10, the second rack 9 is driven to move synchronously. Then, the second rack 9 meshes with the gear 7 and rotates. At the same time, the gear 7 meshes with the first rack 8, causing the height of the smoke extraction platform 5 to rise or fall. At this time, the smoke extraction platform 5 accurately extracts oil fumes from the stove at different heights. Specific implementation method 2:

[0040] Please see Figure 1 , Figure 3 , Figure 5This embodiment of a hot air intelligent range hood includes a main body 1. A collection box 2 is fixedly connected to the top of one side of the main body 1. A flexible ventilation pipe 3, made of tin foil, is connected to one side of the collection box 2. A power supply 4 is fixedly connected to the top of one side of the main body 1. A smoke extraction platform 5 is slidably connected to the middle of the inner wall of the main body 1. A base plate 14 is provided at the bottom of the smoke extraction platform 5. An exhaust fan 6 is fixedly connected to the top of the smoke extraction platform 5. One side of the power supply 4 is electrically connected to the exhaust fan 6 via a wire. The top of the smoke extraction platform 5 is connected to one end of the flexible ventilation pipe 3. Four grooves arranged in a rectangular array are opened at the four corners of the lower surface of the base plate 14. A smoke extraction head 15 is fixedly connected to the middle of the base plate 14. The smoke extraction head 15 is conical in shape and has openings on its outer wall. Multiple through slots are provided. A first threaded rod 16 is rotatably connected to the middle of the lower surface of the cigarette holder 15. An internal threaded groove is opened in the middle of the lower surface of the cigarette holder 15, and the first threaded rod 16 is rotatably connected to the internal threaded groove. A tray 17 is fixedly connected to the bottom end of the first threaded rod 16. The diameter of the tray 17 is larger than the diameter of the largest surface of the cigarette holder 15. Multiple second threaded rods 18 are rotatably connected to the lower surface of the main body 1 in a rectangular array. Multiple internal threaded grooves are opened in a rectangular array on the lower surface of the main body 1, and the second threaded rods 18 mesh with the internal threaded grooves. Insert blocks 19 are fixedly connected to the bottom ends of multiple second threaded rods 18. The insert blocks 19 are L-shaped and correspond to the grooves arranged in a rectangular array on the bottom of the base plate 14.

[0041] In this embodiment of a hot air intelligent range hood, it should be noted that the smoke extraction head 15 and the tray 17 allow for disassembly of the smoke extraction head 15 and the base plate 14 during use, eliminating the need for screw fixing. This prevents the screws from slipping and becoming difficult to disassemble due to long-term smoke extraction. Furthermore, the tray 17 protects the bottom of the smoke extraction head 15, preventing oil condensation into grease droplets that fall onto the stove below. This makes disassembling and cleaning the smoke extraction head 15 more convenient and quick, and also prevents grease from dripping onto the stove.

[0042] The working principle of the above embodiment is as follows: Power 4 is turned on, and the exhaust fan 6 is turned on through the power cord. Then, the exhaust fan 6 draws up the oil fumes and puts them into the soft ventilator 3. The soft ventilator 3 then passes the oil sludge into it. When the oil fumes are being drawn out, if there are large amounts of oil fumes, they will condense into oil droplets at the bottom of the smoke head 15. As the oil fumes accumulate, the oil droplets will fall down. At this time, the first threaded rod 16 is screwed to the bottom of the smoke head 15 through the threaded part, so that the tray 17 collects the oil droplets at the bottom of the smoke head 15. When it is necessary to clean the smoke head 15, the multiple second threaded rods 18 are turned so that the insert 19 no longer clamps the base plate 14, thereby removing the base plate 14 and the smoke head 15 for cleaning. The base plate 14 and the smoke head 15 are fixed by clamping to avoid conventional screw fixing. Screws slip after long-term oil fume fumes, increasing the difficulty of disassembly.
