[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A range hood designed for easy maintenance includes a range hood body 1. The bottom of the range hood body 1 has two engaging structures 2 on both sides. Each engaging structure 2 includes a fixing block 21. The fixing block 21 has a first sliding groove 22 inside, a first groove 23 on one side of the first sliding groove 22, and a second groove 24 on one side of the first groove 23. A lever 25 is slidably connected inside the first sliding groove 22. A threaded rod 26 is rotatably connected inside the lever 25. One end of the threaded rod 26 is fixedly connected to a plug 27. A spring 28 is fixedly connected to one side of the lever 25, and a hand-tightening knob 29 is rotatably connected to the other end of the threaded rod 26. The bottom of the range hood body 1 has a filter structure 3, which includes a mesh cover 31. The surface of the mesh cover 31 is fixedly connected to a hanging ear 3. 2. A filter screen 33 is attached to the surface of the hanging ear 32. A strainer plate 34 is fixedly connected to the bottom of the mesh cover 31. A slot 35 is provided at the bottom of the strainer plate 34. A sliding groove 36 is provided on one side of the slot 35. A sliding groove 37 is provided at the top of the slot 35 and the sliding groove 36. A sludge collection box 38 is movably connected to the bottom of the strainer plate 34. A fixing rod 39 is fixedly connected to the top of the sludge collection box 38. A locking block 310 is fixedly connected to the top of the fixing rod 39. Slots 311 are provided on both sides of the mesh cover 31. A locking structure 2 is provided. During installation, the lever 25 is moved to drive the insertion rod 27 into the sliding groove 22 via the threaded rod 26. At this time, the spring 28 is compressed, which makes the top of the mesh cover 31 and the bottom of the smoke machine body 1 fit together, so that the slots 311 and the sliding groove 311 fit together. After aligning the insert rod 27 with the 11, release the lever 25. Under the action of the spring 28, push the lever 25 to move, thus inserting the insert rod 27 into the slot 2 311, thereby fixing the mesh cover 31 to the bottom of the range hood body 1. To remove, move the lever 25 to remove the insert rod 27 from the slot 2 311, and the mesh cover 31 can be removed. The connection between the mesh cover 31 and the range hood body 1 does not require bolts but is connected by a plug-in method, making installation and disassembly more convenient and facilitating the maintenance of the range hood. A locking structure 2 and a filter structure 3 are provided. The filter screen 33 is installed on the top of the mesh cover 31 through the interlocking of the square groove 1 and the hanging ear 32. When installing the sludge collection box 38, move the locking block 310 into the slot 1 35, so that the locking block 31... 0 enters the slide groove 37, rotates the sludge collection box 38, the locking block 310 rotates in the slide groove 37, and the fixing rod 39 rotates in the slide groove 2 36, thereby disengaging the locking block 310 from the slot 1 35, and thus locking the sludge collection box 38 into the bottom of the drain plate 34. At the same time, the threaded rod 26 is connected to the hand-tightening knob 29 and the lever 25 by threads. Rotating it can separate the hand-tightening knob 29, the threaded rod 26 and the lever 25 from each other. After removing the threaded rod 26 and the hand-tightening knob 29, the spring 28 and the spring 28 can be removed from the slide groove 1 22, which makes it easy to remove the various parts of the locking structure 2 for cleaning and replacement. It is convenient to install and disassemble the filter screen 33, the sludge collection box 38 and the various parts of the locking structure 2 for cleaning and replacement.

[0024] Furthermore, the inner walls of groove 23 and slide 22 do not contact the outer surface of threaded rod 26, so that threaded rod 26 will not interfere with the inner walls of groove 23 and slide 22 when rotating. The two ends of threaded rod 26 are supported by groove 24 and insert rod 27 respectively.

[0025] Furthermore, the lever 25 penetrates the bottom of the slide groove 22, and one end of the threaded rod 26 penetrates the groove 24 and the groove 23 and is rotatably connected to the hand-tightening knob 29. The surface of the hand-tightening knob 29 is provided with a rubber pad layer. Both the lever 25 and the hand-tightening knob 29 are threadedly connected to the threaded rod 26. The threaded connection makes it easier to install and disassemble the lever 25 and the hand-tightening knob 29 with the threaded rod 26. The hand-tightening knob 29 limits the threaded rod 26 and the insertion rod 27.

[0026] Furthermore, one end of the spring 28 is fixedly connected to the surface of the lever 25, and the other end of the spring 28 abuts against the inner wall of the groove 23. The spring 28 is sleeved on the outside of the threaded rod 26. The spring 28 and the threaded rod 26 do not contact each other. When there is no external force, the lever 25 is pushed by the spring 28. The lever 25 drives the insert rod 27 to move through the threaded rod 26, so that the insert rod 27 moves to the outside of the slide groove 22.

[0027] Furthermore, the insertion rod 27 penetrates the inner wall of the slide groove 22 on the side away from the groove 23 and is inserted into the slot 311. Through the cooperation of the insertion rod 27 and the slot 311, the mesh cover 31 is fixed to the bottom of the smoke machine body 1.

[0028] Furthermore, the hanging ear 32 is L-shaped, and a square groove is provided on the surface of the filter screen 33. The filter screen 33 is hung on the surface of the hanging ear 32 through the square groove, which makes it easy to hang the filter screen 33 on the top of the mesh cover 31 and also makes it easy to remove it for cleaning and replacement.

[0029] Furthermore, slot 1 35, slide 2 36 and slide 3 37 are interconnected. The radius of the locking block 310 is larger than the radius of the fixing rod 39. The radius of slot 1 35 is the same as that of the locking block 310. The locking block 310 is slidably connected in slot 1 35 and slide 3 37. The fixing rod 39 is slidably connected in slide 2 36. When installing the sludge storage box 38, the locking block 310 is moved into slot 1 35 so that the locking block 310 enters slide 3 37. When the sludge storage box 38 is rotated, the locking block 310 rotates in slide 3 37, and the fixing rod 39 rotates in slide 2 36, thereby causing the locking block 310 to be misaligned with slot 1 35, and thus the sludge storage box 38 is locked onto the bottom of the drain plate 34.

[0030] Working principle: During installation, moving the lever 25 via the threaded rod 26 moves the insertion rod 27 into the first slide groove 22. At this time, the spring 28 is compressed, bringing the top of the mesh cover 31 and the bottom of the range hood body 1 into contact. After aligning the second slot 311 with the insertion rod 27, the lever 25 is released. Under the action of the spring 28, the lever 25 is pushed to move, thereby inserting the insertion rod 27 into the second slot 311, thus fixing the mesh cover 31 to the bottom of the range hood body 1. When installing the sludge collection box 38, the locking block 310 is moved into the first slot 35, so that the locking block 310 enters the third slide groove 37. Rotating the sludge collection box 38 causes the locking block 310 to rotate within the third slide groove 37, and the fixing rod 39 rotates within the second slide groove 36, thereby aligning the locking block 310 with the insertion rod 27. The slot 35 is offset, thus locking the sludge box 38 to the bottom of the drain plate 34. After long-term use, the lever 25 is turned to remove the insert rod 27 from the slot 311, and the screen cover 31 can be removed. The filter screen 33 is installed on the top of the screen cover 31 through the interlocking of the square slot 1 and the hanging ear 32. The filter screen 33 can be removed for cleaning. The sludge box 38 can be removed for cleaning by rotating it. At the same time, the threaded rod 26 is connected to the hand-tightening knob 29 and the lever 25 by the thread. Rotating it can separate the hand-tightening knob 29, the threaded rod 26 and the lever 25. After removing the threaded rod 26 and the hand-tightening knob 29, the spring 28 can be removed from the slide slot 22, making it easy to remove the various parts of the locking structure 2 for cleaning and replacement.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
