Description

Technical Field

[0001] This application relates to the technical field of vacuum cleaner motors, and more specifically, to a shock-absorbing mechanism for a vacuum cleaner motor. Background Art

[0002] The vacuum cleaner motor is the heart of the vacuum cleaner. The main types of vacuum cleaner motors are: dry-suction vacuum cleaner motors (THRU-FLOW), and wet-dry vacuum cleaner motors (BY-PASS). The vacuum cleaner motor consists of two parts: the motor part and the fan part. Since the vacuum cleaner motor has high requirements for rotational speed, generally 20,000 - 30,000 revolutions per minute, the motor mainly uses series-excited motors, also known as series-wound motors.

[0003] In the vacuum cleaners we commonly see, the motor is usually directly fixed to the bottom plate, and this connection method is called "hard connection". When the vacuum cleaner motor is in operation, especially during the startup and shutdown phases, the motor will generate certain vibrations. Since the connection between the motor and the bottom plate is direct and fixed, lacking an effective buffering and guiding mechanism, it will have an adverse impact on the overall stability of the vacuum cleaner. When the vibration force accumulates to a certain extent, the vacuum cleaner is prone to instability and may even tip over, which will damage parts such as the outer shell and accessories of the vacuum cleaner, affecting its appearance and normal use function, and will also damage the key internal components, resulting in the vacuum cleaner being unable to work properly and requiring repair or replacement of parts, thus increasing the usage cost and repair difficulty.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application; it is obvious that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0029] Referring to Figures 1-6 , a shock-proof mechanism for a vacuum cleaner motor, including a protective cover 1. A motor 2 is arranged inside the protective cover 1. A bottom plate 3 is arranged at the bottom of the protective cover 1. A receiving plate 4 is arranged at the top of the bottom plate 3. A shock-proof component is arranged between the bottom plate 3 and the receiving plate 4. A fixing component is arranged between the protective cover 1 and the receiving plate 4;

[0030] The shock-proof component includes a first shock-absorbing spring 8 and a second shock-absorbing spring 12. The numbers of the first shock-absorbing spring 8 and the second shock-absorbing spring 12 are both set to be multiple. The multiple first shock-absorbing springs 8 and second shock-absorbing springs 12 reduce the vibration of the protective cover 1.

[0031] Referring to Figures 1-6 , a plurality of first sliding grooves 6 are opened on the inner bottom wall of the bottom plate 3. A first sliding block 7 is slidably connected inside each first sliding groove 6. Each first shock-absorbing spring 8 is respectively located inside the corresponding first sliding groove 6. One end of each first shock-absorbing spring 8 is fixedly connected to the inner wall of the corresponding first sliding groove 6. One end of each first shock-absorbing spring 8 is fixedly connected to one side of the corresponding first sliding block 7. A fixing block 5 is fixedly connected to the bottom of the receiving plate 4. Connecting rods 9 are arranged between the outer walls of the plurality of first sliding blocks 7 and the fixing block 5. One end of each connecting rod 9 is rotatably connected to the corresponding first sliding block 7. The other end of each connecting rod 9 is rotatably connected to the outer wall of the fixing block 5. A plurality of second sliding grooves 11 are opened on the inner wall of the bottom plate 3. A second sliding block 13 is fixedly connected to the inner bottom wall of each second sliding groove 11. Each second sliding block 13 is slidably connected to the corresponding second sliding groove 11. The top end of each second shock-absorbing spring 12 is fixedly connected to the corresponding second sliding block 13. A damper 10 is arranged inside each first shock-absorbing spring 8 and second shock-absorbing spring 12. A connecting block 14 is fixedly connected to one side of each second sliding block 13. The top ends of the plurality of connecting blocks 14 are fixedly connected to the bottom of the receiving plate 4.

[0032] The shock-absorbing component can play a certain shock-absorbing role when the vacuum cleaner starts and stops. The specific shock-absorbing method is as follows: First, when the vacuum cleaner starts or stops and generates vibrations, the receiving plate 4 will receive the vibration force transmitted from the protective cover 1. At this time, the fixing block 5 will move along with the movement of the receiving plate 4. The movement of the fixing block 5 will drive the connecting rod 9 to move, causing the connected first slider 7 to slide in the first chute 6. The sliding of the first slider 7 will compress or stretch the first shock-absorbing spring 8, and the first shock-absorbing spring 8 will absorb and buffer part of the vibration energy in this process. At the same time, the vibration of the receiving plate 4 will cause the connecting block 14 to drive the second slider 13 to slide in the second chute 11, thereby compressing or stretching the second shock-absorbing spring 12, and the second shock-absorbing spring 12 will also absorb and buffer part of the vibration energy. The damper 10 provided inside each first shock-absorbing spring 8 and second shock-absorbing spring 12 can consume the vibration energy, further reducing the transmission of vibrations and enhancing the shock-absorbing effect, thus effectively reducing the impact of the vibrations generated during the operation of the vacuum cleaner motor 2 on the overall structural stability.

[0033] The shock-absorbing component improves the stability and safety of the vacuum cleaner, effectively reduces the impact of the vibrations generated during the operation of the motor 2 on the overall structure, reduces the risk of the vacuum cleaner tipping over due to vibrations, avoids damaging the vacuum cleaner and potential safety hazards, effectively reduces the transmission of vibrations to the vacuum cleaner housing and handle, makes the operation process smoother and more comfortable, reduces the fatigue of the user, and reduces the impact and wear of the vibrations on the motor 2 and other components, reduces the probability of faults occurring, enables the vacuum cleaner to work properly for a longer time, and extends the service life of the vacuum cleaner.

[0034] Refer to Figure 2 , the fixing component includes insertion rods 15. The number of insertion rods 15 is set to be multiple. Multiple insertion rods 15 are fixedly connected to the bottom of the protective cover 1. A first threaded hole 16 is formed inside each insertion rod 15. A plurality of insertion holes 19 are formed in the top of the receiving plate 4. The plurality of insertion holes 19 are arranged corresponding to the plurality of insertion rods 15. A second threaded hole 18 is formed on one side of each insertion hole 19. A screw rod 17 is provided on one side of each second threaded hole 18. One end of each screw rod 17 passes through the corresponding second threaded hole 18 and is threadedly connected to the corresponding first threaded hole 16.

[0035] The fixing component can effectively fix the protective cover 1. The specific fixing method is as follows: First, align the multiple insertion rods 15 at the bottom of the protective cover 1 with the corresponding insertion holes 19 at the top of the receiving plate 4 and insert them. When the insertion rods 15 are completely inserted into the insertion holes 19, align the first threaded hole 16 with the second threaded hole 18, and then insert one end of the screw rod 17 through the second threaded hole 18 in sequence and screw it into the first threaded hole 16 to achieve threaded connection. Through the cooperation of the multiple screw rods 17 with the corresponding first threaded holes 16 and second threaded holes 18, the protective cover 1 is firmly fixed on the receiving plate 4.

[0036] Through the cooperation of multiple screws 17 and corresponding threaded holes, multi-point fixation can be provided, making the connection between the protective cover 1 and the receiving plate 4 more firm, ensuring that there is no loosening or displacement during the operation of the vacuum cleaner, and the operation is relatively simple. When components such as the motor 2 need to be repaired or replaced, it can be easily disassembled and reinstalled.

[0037] Refer to Figure 1 and Figure 2 , a heat dissipation hole 20 is provided on one side of the protective cover 1. The number of heat dissipation holes 20 is set to be multiple, and the multiple heat dissipation holes 20 are evenly distributed inside the protective cover 1, which helps the heat generated by the motor 2 during operation to be quickly dissipated, avoids damage to the motor 2 due to overheating, and prolongs the service life of the motor 2.

[0038] Working principle: First, when the vacuum cleaner starts or stops and generates vibrations, the receiving plate 4 will receive the vibration force transmitted from the protective cover 1. At this time, the fixed block 5 will move along with the movement of the receiving plate 4. The movement of the fixed block 5 will drive the connecting rod 9 to move, causing the connected first slider 7 to slide in the first chute 6. The sliding of the first slider 7 will compress or stretch the first shock-absorbing spring 8, and the first shock-absorbing spring 8 will absorb and buffer part of the vibration energy during this process; at the same time, the vibration of the receiving plate 4 will cause the connecting block 14 to drive the second slider 13 to slide in the second chute 11, thereby compressing or stretching the second shock-absorbing spring 12, and the second shock-absorbing spring 12 will also absorb and buffer part of the vibration energy. The damper 10 provided inside each of the first shock-absorbing spring 8 and the second shock-absorbing spring 12 can consume the vibration energy, further reducing the transmission of vibrations and enhancing the shock-absorbing effect, thereby effectively reducing the impact of the vibrations generated during the operation of the vacuum cleaner motor 2 on the overall structural stability.

[0039] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
