Four first air guide plates are rotatably connected inside the mounting box. The end of each connecting spring away from the rotating motor is fixedly connected to the back of a first air guide plate. Three second air guide plates are rotatably connected inside the mounting box. This utility model, by setting up a rotating motor, a cross block, a turntable, a connecting shaft, a movable frame, a connecting frame, connecting springs, and first air guide plates, achieves the purpose of controlling the left and right flow of air.

[0004] However, the aforementioned existing technology does not have a backflow prevention function. During use, when encountering severe weather, outdoor airflow and dust will flow back into the range hood from the air outlet, causing the fan to malfunction. Utility Model Content

[0005] The purpose of this utility model is to provide a low-energy range hood micro-airflow exhaust component to solve the problem mentioned in the background art that the prior art does not have an anti-backflow function when in use, and that outdoor airflow and dust will flow back into the range hood from the air outlet during the use of the exhaust pipe in bad weather, thereby causing the fan to malfunction.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a low-energy range hood micro-airflow exhaust component, including an exhaust pipe, a protective mechanism is provided on the outside of the exhaust pipe, and an energy-saving mechanism is provided at one end of the exhaust pipe;

[0007] The protective mechanism includes a protective frame, a rotating shaft rotatably connected to the inner side of the protective frame, a baffle fixedly connected to the outer side of the rotating shaft, a return spring fixedly connected to one end of the baffle, a sealing gasket installed on the outer side of the baffle, a mounting base fixedly connected to the outer side of the protective frame, a strong spring fixedly connected to the inner side of the mounting base, a positioning block fixedly connected to one end of the strong spring, and a handle fixedly connected to the top of the positioning block.

[0008] Preferably, multiple positioning blocks are provided, and one end of each positioning block is engaged with one end of the exhaust pipe.

[0009] Preferably, multiple baffles are provided, and the multiple baffles are arranged in a linear array.

[0010] Preferably, one end of the return spring is fixedly connected to one end of the rotating shaft, and the inner side of the mounting base is in contact with the outer wall of the exhaust pipe.

[0011] Preferably, the energy-saving mechanism includes a mounting housing, inside which an exhaust fan is installed, and one end of the exhaust fan is connected to an oil fume concentration sensor.

[0012] Preferably, a cover plate is hinged to one end of the mounting shell, the cover plate has a through hole on the outside, and a filter screen is snapped into the inside of the mounting shell.

[0013] Preferably, one end of the mounting housing is fixedly connected to one end of the exhaust pipe, and one end of the oil fume concentration sensor is connected to one end of the mounting housing.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] Firstly, this utility model involves pulling a handle to engage the mounting base with the outside of the exhaust pipe. Releasing the handle causes a powerful spring to push a positioning block downwards, locking it into the exhaust pipe and thus installing the protective frame on the outside of the exhaust pipe. This facilitates the installation and removal of the protective frame. When the range hood is not in use, the baffle is vertical, blocking the exhaust pipe's outlet with multiple baffles and improving the seal with a sealing gasket, preventing external sand and dust from flowing back into the exhaust pipe. When the range hood is in use, the airflow from the exhaust fan pushes the baffle, opening the exhaust pipe's outlet and allowing fumes to escape. After use, the return spring resets the baffle, automatically closing it and preventing sand and dust from flowing back into the exhaust pipe.

[0016] Secondly, this utility model installs the mounting shell on the stovetop and detects the oil fume concentration using an oil fume concentration sensor. Based on the oil fume concentration, the system controls the exhaust fan's power to achieve energy-saving operation. The exhaust fan then draws in the oil fumes, which enter the mounting shell through the through-holes on the outside of the cover plate. The oil fumes are then filtered and blocked by a filter screen. Because the cover plate is hinged, it is easy to open the cover plate and remove the snap-on filter screen for cleaning.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Please see Figure 1-5 A low-energy range hood micro-airflow exhaust component includes an exhaust pipe 1, a protective mechanism 2 is provided on the outside of the exhaust pipe 1, and an energy-saving mechanism 3 is provided at one end of the exhaust pipe 1.

[0027] The protective mechanism 2 includes a protective frame 21, a rotating shaft 22 is rotatably connected to the inner side of the protective frame 21, a baffle 23 is fixedly connected to the outer side of the rotating shaft 22, a return spring 24 is fixedly connected to one end of the baffle 23, a sealing gasket 25 is installed on the outer side of the baffle 23, a mounting base 26 is fixedly connected to the outer side of the protective frame 21, a strong spring 27 is fixedly connected to the inner side of the mounting base 26, a positioning block 28 is fixedly connected to one end of the strong spring 27, and a handle 29 is fixedly connected to the top of the positioning block 28.

[0028] Multiple positioning blocks 28 are provided, and one end of each positioning block 28 is engaged with one end of the exhaust pipe 1.

[0029] Multiple baffles 23 are provided, and the multiple baffles 23 are arranged in a linear array.

[0030] One end of the return spring 24 is fixedly connected to one end of the rotating shaft 22, and the inner side of the mounting base 26 is in contact with the outer wall of the exhaust pipe 1.

[0031] Through the above technical solution, by pulling the handle 29, the mounting base 26 is engaged with the outside of the exhaust pipe 1. Then, by releasing the handle 29, the force of the strong spring 27 pushes the positioning block 28 down, causing the positioning block 28 to engage inside the exhaust pipe 1, thereby installing the protective frame 21 on the outside of the exhaust pipe 1, facilitating the disassembly and installation of the protective frame 21. When the range hood is not in use, the baffle 23 is vertical, blocking the exhaust port of the exhaust pipe 1 with multiple baffles 23 and improving the sealing performance with the sealing gasket 25, thus preventing external wind and sand from flowing back into the exhaust pipe 1. When the range hood is in use, the air force blown by the exhaust fan 32 pushes the baffle 23, thereby opening the exhaust port of the exhaust pipe 1, allowing the fumes to be discharged. After use, under the force of the return spring 24, the baffle 23 is reset, allowing the baffle 23 to close automatically, thus achieving the effect of preventing wind and sand from flowing back into the exhaust pipe 1.

[0032] Example 2

[0033] Please see Figure 1-5 Furthermore, based on Embodiment 1, the energy-saving mechanism 3 includes a mounting shell 31, an exhaust fan 32 is installed inside the mounting shell 31, and a wire at one end of the exhaust fan 32 is connected to an oil fume concentration sensor 33.

[0034] A cover plate is hinged to one end of the mounting housing 31. The cover plate has a through hole on its outside, and a filter screen 34 is snapped into the inside of the mounting housing 31.

[0035] One end of the mounting housing 31 is fixedly connected to one end of the exhaust pipe 1, and one end of the oil fume concentration sensor 33 is connected to one end of the mounting housing 31.

[0036] Through the above technical solution, the mounting shell 31 is installed on the stove, and the oil fume concentration is detected by the oil fume concentration sensor 33. Then, the air force of the exhaust fan 32 is controlled according to the oil fume concentration to achieve energy-saving operation. Then, the oil fume is drawn out by the exhaust fan 32, so that the oil fume enters the mounting shell 31 through the through hole on the outside of the cover plate, and then the oil fume is filtered and blocked by the filter screen 34. Since the cover plate is hinged, it is easy to open the cover plate and remove the snap-on filter screen 34 for cleaning.
