Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of integrated smoke hood collectors, in particular to a built-in fan structure of an integrated smoke hood collector. Background Art
[0002] An all-in-one smoke hood refers to a machine that combines a fan and an oil fume purification part into a whole. In addition to the oil fume purification function, it also has a smoke exhaust function. When the all-in-one smoke hood is in use, the fan inside the machine needs to be disassembled regularly. The reason is to maintain the purification effect of the equipment and extend its service life. Regular disassembly and cleaning can remove oil and dust on the fan blades and internal structure, and prevent oil fume accumulation from affecting the smoke exhaust effect.
[0003] At present, the installation structure of the internal fan is generally fixed by bolts. When the smoke hood is installed, the installation height is generally higher than the height of the cleaning personnel. Therefore, the cleaning personnel carry tools and climb up to remove the fan before cleaning. When the cleaning personnel install and disassemble the built-in fan, they need to tighten the bolts multiple times, and the disassembly efficiency of the built-in fan is low. Based on this, a built-in fan structure of an integrated smoke hood is proposed. Utility Model Content

[0023] like Figures 1 to 6 As shown, the smoke hood integrated machine has a built-in fan structure in this embodiment, including a smoke hood body 1, a filter shell 2 is installed on the upper end of the smoke hood body 1, and there are multiple filter shells 2. The filter shells 2 are used to perform multi-stage filtering of oil smoke, and a mounting shell 3 is installed at one end of the filter shell 2. The mounting shell 3 is used to install the built-in fan, and two fixing blocks 4 are installed inside the mounting shell 3. The upper ends of the two fixing blocks 4 are both provided with sliding grooves 5. Sliding blocks 6 are slidably installed inside the sliding grooves 5. The sliding blocks 6 are installed inside the sliding grooves 5 in a sliding manner. A limiting component is installed at one end of the fixed block 4 in front of the moving block 6. The limiting component is used to keep the sliding block 6 in a suitable position, so as to facilitate the connection of the built-in fan outlet with the corresponding interface. A fixing plate 8 is detachably installed on the two sliding blocks 6. A fan casing 9 is installed on the upper end of the fixing plate 8. A driving motor 10 is installed inside the fan casing 9. A centrifugal impeller 11 is installed at the output end of the driving motor 10. The centrifugal impeller 11 is driven by the driving motor 10 to rotate, and the centrifugal impeller 11 generates suction to realize the extraction of oil smoke.
[0024] Specifically, the limiting assembly includes a fixing frame 701, a limiting rod 702, a moving ring 703, an elastic spring 704 and a pull rope 705. The fixing frame 701 is installed at one end of the fixing block 4 in front of the sliding block 6. The limiting rod 702 is slidably installed at one end of the fixing frame 701 through a through hole. One end of the limiting rod 702 extends into the interior of the sliding groove 5. The surface of the limiting rod 702 is located inside the fixing frame 701 and a moving ring 703 is installed. The limiting rod 702 between the moving ring 703 and the fixing frame 701 is fixed. An elastic spring 704 is installed on the surface, and a pull rope 705 is installed at one end of the limit rod 702. One end of the two pull ropes 705 is connected. By using the elastic spring 704 to push the movable ring 703 and the limit rod 702, the limit rod 702 blocks the sliding block 6, thereby limiting the sliding block 6. By pulling the pull rope 705 to drive the limit rod 702 to move, the blocking of the sliding block 6 by the limit rod 702 can be released, making it convenient to slide the fixed plate 8 and the sliding block 6 out of the inside of the mounting shell 3.
[0025] Furthermore, a slope 12 is provided at the other end of the limit rod 702. With the setting of the slope 12, the sliding block 6 can directly push the limit rod 702, so that the sliding block 6 can slide directly to the rear of the limit rod 702 without manually pulling the pull rope 705 to drive the limit rod 702 to move.
[0026] Furthermore, mounting grooves 13 are provided at the front and rear parts of the upper end of the sliding block 6, and mounting plates 14 are installed at the front and rear parts of both ends of the fixing plate 8, and the mounting plates 14 are respectively located inside the mounting grooves 13, and a fixing rod 15 is installed at the upper end of the sliding block 6 on one side of the mounting groove 13, and a fixing ring 16 is installed at the upper end of the fixing rod 15, and the lower end of the fixing ring 16 is located on the surface of the fixing rod 15 and an elastic spring 2 17 is installed, and a locking plate 18 is rotatably installed on the surface of the fixing rod 15 below the elastic spring 2 17, and the locking plate 18 is located above the mounting plate 14. By rotating the locking plate 18, the locking plate 18 no longer blocks the mounting plate 14, and the fixing plate 8 and the mounting plate 14 can be removed from the sliding block 6, so that the fan casing 9 can be removed from the inside.
[0027] Furthermore, an elastic spring 3 19 is installed at the rear of the sliding groove 5, and the sliding block 6 is located in front of the elastic spring 3 19. The setting of the elastic spring 3 19 facilitates the blocking of the limit rod 702 when the sliding block 6 is moved out, making it convenient to remove the sliding block 6.
[0028] Furthermore, the fan casing 9 is composed of two semi-annular casings 901, and connecting plates 20 are installed on both sides of the surface of the semi-annular casing 901. The two adjacent connecting plates 20 are connected by bolts. The drive motor 10 is connected to a semi-annular casing 901 through a frame. By removing one semi-annular casing 901, the centrifugal impeller 11 is exposed to the outside, which facilitates the cleaning and maintenance of the surface of the centrifugal impeller 11 to avoid affecting the smoke exhaust effect.
[0029] The method of using this embodiment is as follows: when it is necessary to clean and maintain the inside of the fan casing 9, the baffle on the mounting shell 3 is opened, and the two limit rods 702 are moved by pulling the pull rope 705, and the limit rod 702 releases the limit on the sliding block 6. At the same time, the elastic spring 2 17 restores and pushes the sliding block 6, so that the sliding block 6 blocks the limit rod 702. By pulling the fixed plate 8, the fixed plate 8 can be slid out from the inside of the mounting shell 3, and the locking plate 18 is rotated so that the locking plate 18 no longer blocks the mounting plate 14. The fixed plate 8 and the mounting plate 14 are removed from the sliding block 6, and a semi-annular shell 901 is removed to expose the centrifugal impeller 11 to the outside. The centrifugal impeller 11 is maintained and cleaned, and can be reinstalled after cleaning.
[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
