Description

[Technical field]

[0001] The invention relates to the technical field of range hoods, and in particular to a quick-installation wind wheel. [Background technology]

[0002] In order to improve the kitchen fume problem and create a good kitchen environment, more and more people choose to install range hoods in the kitchen to collect or discharge the harmful exhaust gas and fume generated during cooking to the outside. The most core component of a range hood is the fan, and the fan wheel is the most critical component of the fan, which directly affects the aerodynamic performance of the range hood.

[0003] At present, the existing range hoods generally install the wind wheel on the motor shaft by matching the wind wheel nut with the stud on the motor shaft. When installing, the installer must hold the wind wheel with one hand to prevent the wind wheel from rotating, and tighten the wind wheel nut with the other hand. The two-hand operation is very labor-intensive and is not conducive to mass production. In addition, the tightness of the wind wheel nut is different when it is manually tightened, which is easy to be twisted crooked or not tightened. The effect of locking the wind wheel is not good, causing the range hood to shake during operation. In addition, when the range hood is used for a long time, oil will clog the screw thread, making it difficult to disassemble the wind wheel. Disassembling the wind wheel by force will easily cause the wind wheel to deform and the motor shaft to be skewed, which will destroy the dynamic balance of the wind wheel and cause the range hood to shake during operation. Therefore, the present invention is generated based on the above shortcomings. [Summary of the invention]

The present invention drives the locking device 4 to lock or loosen the motor shaft 3 through the driving device 5, and the operation is simple, so that the installation and disassembly of the wind wheel are convenient and quick, and the occurrence of the situation such as uneven installation of the wind wheel, damage and shaking of the wind wheel due to manual locking nuts is avoided, and after the locking device 4 locks the motor shaft 3, the installer can use the locking device 6 to lock the driving device 5 so that the driving device 5 remains in a fixed position, so that the locking device 4 can keep locking the motor shaft 3, and prevent the wind wheel from falling due to loosening during cleaning or after the range hood is used for a long time, and the locking and installation of the wind wheel has a good effect, and is safe and reliable.

[0029] The mounting base 2 includes a first seat plate 22, a second seat plate 23 and a connecting block 21 installed between the first seat plate 22 and the second seat plate 23. The locking device 4, the driving device 5 and the locking device 6 are installed between the first seat plate 22 and the second seat plate 23. The first seat plate 22 and the second seat plate 23 are respectively provided with a first axial hole 221 and a second axial hole 231 through which the motor shaft passes. The hub of the wind wheel 1 is also connected to a wind wheel sleeve 9. During installation, the motor shaft passes through the third axial hole 91 of the wind wheel sleeve 9 and then enters the mounting base 2 from the first axial hole 221.

[0030] The locking device 4 includes a slider 41 driven to slide by the driving device 5 . The slider 41 is provided with a locking portion 421 which can lock the motor shaft 3 when the slider 41 slides toward one side of the motor shaft 3 .

[0031] Furthermore, two sliders 41 are provided, and each slider 41 is provided with a corresponding locking portion 421 . The two locking portions 421 are relatively spaced apart and can clamp the motor shaft 3 when the slider 41 slides.

[0032] Specifically, Figure 3 and Figure 5 As shown, the slider 41 is provided with a first slide groove 412, a locking block 42 is provided in the first slide groove 412 so as to slide up and down, a first inclined surface 4121 is provided in the first slide groove 412, a second inclined surface 422 matching with the first inclined surface 412 is provided on the locking block 42, an external thread 31 is provided on the motor shaft 3, a locking portion 421 is a threaded opening provided on the locking block 42 matching with the external thread 31, and two positioning springs 43 are provided on the mounting seat 2 respectively pressing on the upper and lower ends of the locking block 42. In this way, the locking block 42 can slide up and down in the first slide groove 412 of the slider 41, and when the locking block 42 is locked and matched with the motor shaft 3, the locking block 42 can automatically slide up and down to adjust so that the threaded opening of the locking block 42 matches with the external thread 31 on the motor shaft 3, so that it is not necessary to align the threaded opening with the external thread 31 during installation, so that the wind wheel can be installed conveniently and quickly.

[0033] The driving device 5 includes a driving block 51 slidably disposed on the mounting seat 2 and linked to the slider 41. The mounting seat 2 is provided with a first spring 53 capable of pressing the driving block 51 to reset. When the user manually pushes the driving block 51, the driving block 51 drives the slider 41 away from the motor shaft 3, thereby driving the locking block 42 to unlock the motor shaft 3. When the motor shaft 3 needs to be locked, the first spring 53 presses the driving block 51 to reset so that the slider 41 drives the locking block 42 to re-lock the motor shaft 3.

[0034] The driving block 51 is provided with a lever arm 511 which can move the slider 41 to slide when the driving block 51 slides, and the slider 41 is provided with a linkage part 411 which cooperates with the lever arm 511 to make the slider 41 and the driving block 51 linked.

[0035] Specifically, the lever arm 511 is provided with a third inclined surface 5111 and a fourth inclined surface 5112, and the linkage part 411 includes two relatively spaced first bosses 4111 and second bosses 4112. The third inclined surface 5111 cooperates with the first boss 411 in a directional manner so that the lever arm 511 drives the slider 41 to approach the motor shaft 3, and the fourth inclined surface 5112 cooperates with the second boss 412 in a directional manner so that the lever arm 511 drives the slider 41 away from the motor shaft 3. The lever arm 511 can slide between the first boss 4111 and the second boss 4112. When the first spring 53 presses the driving block 51 to reset, the third inclined surface 5111 can push the first boss 411 so that the slider 41 drives the locking block 42 to lock the motor shaft 3. When the driving block 51 is manually pushed to slide, the fourth inclined surface 5112 can push the second boss 412 so that the slider 41 drives the locking block 42 to unlock the motor shaft 3.

[0036] The driving block 51 is provided with a positioning portion 512, the mounting seat 2 is provided with a second slide groove 211, and the locking device 6 comprises a locking block 61 slidably arranged in the second slide groove 211, a push block 62 which can drive one end of the locking block 61 to extend or retract into the second slide groove 211 to lock or unlock the positioning portion 512, and a second spring 63 which can press the push block 62 to reset. When the user pushes the push block 62, the push block 62 can drive the locking block 61 to retract into the second slide groove 211, and the positioning portion 512 is unlocked at this time, so that the driving block 51 can be driven to slide so that the locking device 4 locks or unlocks the motor shaft 3, and after the locking device 4 locks or unlocks the motor shaft 3, the second spring 63 presses the push block 62 to reset so that the push block 62 drives the locking block 61 to extend out of the second slide groove 211 to position the positioning portion 512, so that the driving block 51 is fixed in a relative position, so that the locking device 4 keeps the state of locking or unlocking the motor shaft 3.

[0037] Specifically, the locking block 61 is provided with a fifth inclined surface 611 and a sixth inclined surface 612, and the push block 62 is provided with a seventh inclined surface 621 that cooperates with the fifth inclined surface 611 to retract one end of the locking block 61 into the second slide groove 211 when the push block 62 slides, and an eighth inclined surface 622 that cooperates with the sixth inclined surface 612 to extend one end of the locking block 61 out of the second slide groove 211 when the push block 62 slides. The seventh inclined surface 621 can push the fifth inclined surface 611 to retract the locking block 61 into the second slide groove 211, and the eighth inclined surface 622 can push the sixth inclined surface 612 to extend one end of the locking block 61 out of the second slide groove 211 when the second spring 63 presses the push block 62 to reset.

[0038] like Figure 5 As shown, the mounting seat 2 is provided with a cover body 7 fixed on the wind wheel 1, and a spacer block 8 which can be inserted between the two locking parts 42 and can be pushed out of the two locking parts 42 by the motor shaft 3 is provided between the cover body 7 and the mounting seat 2, and a compression spring 10 which presses the spacer block 8 to be inserted between the two locking parts 42 is provided between the spacer block 8 and the cover body 7. The cover body 7 can protect the locking device 4, the driving device 5 and the locking device 6 arranged on the mounting seat 2. When the motor shaft 3 is not connected, one end of the spacer block 8 can be inserted between the two locking parts 421, so that the locking block 42 maintains a state that allows the motor shaft 3 to be inserted. When the motor shaft 3 is inserted, the motor shaft 3 can push the spacer block 8 to release the limit on the two locking blocks 42, so that the motor shaft 3 can be locked. Specifically, as Figure 3 As shown, the cover body 7 is also provided with a first extension hole 72 for one end of the driving block 51 to extend out and a second extension hole 71 for one end of the pushing block 62 to extend out, so that the motor shaft 3 can be locked or unlocked by pressing and pushing the driving block 51 and the pushing block 62 extending out of the cover body 7.

[0039] When the wind wheel needs to be installed on the motor shaft, such as Figure 6As shown, the installer can align the motor shaft 3 with the third shaft hole 91 and insert it, and the motor shaft 3 passes through the first shaft hole 221 into the mounting seat 2, push the spacer block 8, release the limit of the two locking blocks 42, and then Figure 7 As shown, the push block 62 is pressed to resist the elastic force of the second spring 63 to move, and the push block 62 drives the locking block 61 to retract into the second slide groove 211, and the driving block 51 is unlocked. The first spring 53 can press one end of the driving block 51 to extend out of the cover 7, and the driving block 51 drives the slider 41 to approach the motor shaft 3, so that the locking block 42 cooperates with the external thread 31 through the threaded opening to lock the motor shaft, as shown in FIG. Figure 8 As shown, at this time, the push block 62 is released, and the second spring 63 presses the push block 62 to reset, thereby driving the locking block 61 to extend out of the second slide slot 211 to lock the driving block 51, so that the locking device 4 can keep the motor shaft 3 locked to prevent the wind wheel from loosening and falling.

[0040] When it is necessary to remove the wind wheel from the motor shaft, the installer can press the push block 62 and the driving block 51 at the same time. The push block 62 resists the elastic force of the second spring 63 and drives the locking block 61 to retract into the second slide groove 211, and the driving block 51 is unlocked. The driving block 51 drives the sliding block 41 away from the motor shaft 3, so that the locking block 42 is loosened and unlocks the motor shaft 3. At this time, the push block 62 is released, and the second spring 63 presses the push block 62 to reset, thereby driving the locking block 61 to extend out of the second slide groove 211 to lock the driving block 51. When the wind wheel is removed from the motor shaft, the compression spring 10 presses the spacer 8 to insert it between the two locking parts 42, so that the locking block 42 maintains a state that allows the motor shaft 3 to be inserted.
