[0033] Embodiment 1:

[0034] Combined with Figures 1 to 7 , an energy-saving and purifying range hood, comprising:

[0035] A smoke exhaust duct 1, wherein a range hood 2 connected thereto is disposed at the lower end of the smoke exhaust duct 1, and an exhaust fan 3 is embedded at the bottom of the inner side of the smoke exhaust duct 1;

[0036] A range hood 2, wherein a collecting mechanism 4 is disposed at the lower end of the range hood 2, wherein the collecting mechanism 4 comprises a collecting body 401, wherein the top of the collecting body 401 is fixedly connected to the lower end surface of the range hood 2, an air outlet 402 is disposed on the side of the collecting body 401, a collecting box 5 is fixedly connected to the bottom of the collecting body 401, and a rotating sealing plate 403 is rotatably connected to the inner side surface of the collecting body 401, wherein a hole is formed on the rotating sealing plate 403, and the size of the hole is larger than the size of the air outlet 402;

[0037] An annular cover 6 is arranged above the collecting body 401 , and smoke extraction holes 601 are arranged on both sides of the annular cover 6 . A filter net is arranged on the smoke extraction holes 601 . A cleaning mechanism 7 is fixedly arranged inside the annular cover 6 , and the cleaning mechanism 7 is used to clean the oil stains in the collecting mechanism 4 .

[0038] Combined with Figure 7 The annular cover is arranged in an annular cylindrical shape, and openings are arranged on the upper and lower sides of the annular cover. The smoke extraction holes on both sides of the annular cover are connected with the inner side of the annular cover, so as to facilitate the inlet and outlet of smoke.

[0039] In specific implementation, the exhaust fan is started, and the exhaust fan blows the airflow from the range hood to the exhaust duct. The airflow inside the range hood flows in from the exhaust port, passes through the collection mechanism and the smoke extraction hole, and enters the range hood to complete the suction and discharge of the oil smoke. The filter net set on the smoke extraction hole will be used to filter the oil stains to prevent the oil stains from entering the range hood, so as to achieve the purpose of limiting the oil stains in the collection mechanism.

[0040] The preferred implementation of this embodiment is that the collecting body 401 is conical, and there are two of them symmetrically arranged along the length direction of the range hood 2. The inner side of each collecting body 401 is coaxially and tightly provided with a rotating sealing plate 403 connected thereto. The rotating sealing plate 403 opens or closes the air outlet 402 by rotating. A driving device for driving the rotating sealing plates 403 is arranged between the two rotating sealing plates 403. The driving device includes a rotating motor 404, and the output end of the rotating motor 404 is connected to a driving gear 405. The outer ring of the rotating sealing plate 403 is provided with external teeth 406 that cooperate with the driving gear 405. The rotating motor 404 drives the rotating sealing plate 403 to rotate through the driving gear 405.

[0041] Specific design: the collector 401 is in an inverted cone shape, the rotating sealing plate 403 is arranged above the collector 401 and is arranged in close contact with the inner side of the collector 401, and the rotating sealing plate 403 is also designed in an inverted cone shape. The rotating sealing plate 403 is coaxially connected with the collector 401, and the rotating sealing plate 403 rotates so that the hole and the air outlet are staggered or aligned, thereby achieving the technical effect of opening and closing the air outlet.

[0042] In specific implementation, the rotating motor drives the active gear to rotate, and the active gear drives the rotating sealing plate to rotate through the outer teeth matched with it. The hole set on the rotating sealing plate is slightly larger than the air outlet. When the rotating sealing plate rotates so that the hole and the air outlet are aligned, the air outlet is used to extract oil fume; when cleaning is required, the rotating sealing plate rotates a certain angle so that the hole and the air outlet are completely staggered, achieving the technical effect of sealing the air outlet.

[0043] A preferred implementation manner of this embodiment is that a collecting port 407 is provided at the bottom of the collecting body 401, a connecting thread 408 is provided at the outer ring of the bottom of the collecting body 401, the collecting box 5 is circular in shape, and its upper end is fixedly connected to the collecting box 401 through the connecting thread 408, a sealing plate 8 rotatably connected to the bottom of the collecting body 401 is coaxially provided, a water leakage hole 801 is provided on the sealing plate 8, a collecting motor 802 is fixedly connected to the bottom of the collecting body 401, and the output end of the collecting motor 802 is connected to the sealing plate 801, and the collecting motor 802 opens or closes the collecting port 407 by driving the sealing plate 801 to rotate.

[0044] During specific implementation, the leakage hole and the collection port are set to match the size. During normal use, the leakage hole and the collection port are staggered so that the collection port is in a closed state and oil smoke cannot enter through the collection port. When the cleaning device finishes cleaning the oil stains in the collection body, a large amount of sewage with oil stains exists in the collection body. The collection motor drives the sealing plate to rotate so that the leakage hole and the collection port are set correspondingly. At this time, the sewage with oil stains flows into the collection box through the leakage hole and the collection port, and the sewage is collected by the collection box. When the sewage in the collection box is full, the collection box can be disassembled by rotating it, and the sewage with oil stains can be poured out. You only need to clean the collection box.

[0045] When in use, the water leakage hole and the collection port are staggered, the hole and the exhaust port are aligned, and the exhaust fan is started. Under the blowing of the exhaust fan, the oil smoke enters the collection body through the exhaust port, enters the range hood through the exhaust port from the collection body, and finally enters the exhaust duct through the exhaust fan. The filter arranged on the exhaust port filters the oil stains so that the oil stains remain in the collection body. When cleaning, the hole and the exhaust port are staggered so that the exhaust port is completely closed. At this time, the collection body forms a closed space, and the cleaning mechanism arranged in the annular cover cleans the collection mechanism. After cleaning is completed, the water leakage hole is aligned with the collection port, and the sewage generated by cleaning enters the collection box through the water leakage hole and the collection port, completing a cleaning.

[0046] A preferred implementation manner of this embodiment is that a water baffle 602 is arranged on the outer side of the smoke extraction hole 601, and the water baffle 602 includes an arc-shaped water baffle 6-1 arranged on the opposite side of the two annular covers 6 and an elongated water baffle 6-2 arranged on the opposite side of the two annular covers 6, and the heights of the arc-shaped water baffle 6-1 and the elongated water baffle 6-2 are both higher than the smoke extraction hole 601, and the smoke extraction hole 601 is connected to the smoke exhaust duct 1.

[0047] In specific implementation, the arc-shaped water baffle and the elongated water baffle are used to prevent the clean water from flowing out of the collecting body through the smoke exhaust hole during cleaning, thereby affecting the cleaning effect, and ensure that the clean water will not be spilled at will.

[0048] Embodiment 2:

[0049] Based on Example 1, Figure 8In the preferred implementation of this embodiment, the cleaning structure 7 is arranged above the collecting mechanism 4, and includes a water collecting chamber 701. The lower end of the water collecting chamber 701 is conical, and the lower end of the water collecting chamber 701 is provided with a plurality of high-pressure nozzles 702 connected thereto. Clean water with detergent is placed in the water collecting chamber 701, and the high-pressure nozzles 702 are used to spray the clean water to the collecting body 401. A cleaning motor 703 is arranged at the bottom of the water collecting chamber 701, and a stirring shaft 704 is connected to the output end of the cleaning motor 703. A plurality of stirring blades 705 are arranged on the stirring shaft 704, and the cleaning motor 703 is used to drive the stirring blades 705 to rotate to quickly stir the clean water.

[0050] In specific implementation, the high-pressure nozzle sprays clean water with detergent into the collection body; at the same time, the cleaning motor is started, the cleaning motor drives the stirring to rotate rapidly, and the stirring blades are set on the lower outer ring of the stirring shaft to quickly clean the entire collection mechanism. This improves the targeted cleaning and reduces the frequency of comprehensive cleaning of the entire range hood.

[0051] A preferred implementation method of this embodiment is that a water inlet pipe 706 connected to the water collecting chamber 701 is provided on the top thereof, and a water inlet is provided on the upper end of the water inlet pipe 706 after extending out of the range hood 2 . The water inlet pipe 706 is used to transport clean water with detergent into the water collecting chamber 701 .

[0052] Clean water is added to the water collecting chamber through the water inlet pipe.

[0053] A preferred implementation manner of this embodiment is that the collecting mechanism 4 and the cleaning mechanism 7 are both symmetrically arranged, and a cavity is arranged above the cleaning mechanism 7 and between the range hood 2 , and the cavity is used to connect the smoke extraction hole 601 and the smoke exhaust duct 1 .

[0054] When the present invention is implemented, the two collecting mechanisms and the cleaning mechanism arranged on the range hood correspond to the double stove design of the existing gas stove, which is convenient for faster extraction and exhaust of the oil smoke.

[0055] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
