Description

An adjustable wind speed blower Technical Field

[0001] This utility model relates to the field of adjustable wind speed blower technology, and more specifically, it relates to an adjustable wind speed blower. Background Technology

[0002] In the field of modern cleaning equipment, blow-vacuum cleaners are important cleaning tools, and their performance and reliability are directly related to cleaning effect and work efficiency. However, blow-vacuum cleaners on the market today have significant technical defects in terms of practicality and reliability. These problems not only affect the cleaning effect, but may also lead to energy waste and reduced work efficiency.

[0003] The primary problem is that the wind speed is usually not adjustable. Existing technologies generally suffer from the serious issue of fixed wind speed: First, traditional blowers and vacuums use a single fixed wind speed design, making it impossible to adjust the wind force according to different cleaning objects; second, when dealing with different material surfaces, the fixed wind speed mode may result in excessive wind force damaging items or insufficient wind force for incomplete cleaning; third, different environmental conditions and cleaning needs require corresponding adjustments to the wind speed intensity; furthermore, a single wind speed design cannot meet the requirements of fine cleaning operations; finally, this inflexible adjustment not only affects the cleaning effect but may also lead to energy waste and increase the limitations of equipment use.

[0004] The most serious problem is structural instability. Although some improved equipment has achieved wind speed regulation, it suffers from serious defects in structural stability. First, most existing wind speed regulation devices use simple mechanical structures. During equipment operation, the continuous impact of high-speed airflow will generate stress on the regulation structure. Second, the continuous vibration generated during equipment operation will cause the regulation mechanism to gradually loosen. This structural instability will not only cause the adjusted wind speed parameters to deviate, but may also cause unstable cleaning effect, affect work quality, and may even cause a decline in the performance of the entire blowing and suction system.

[0031] Please refer to Figures 1-5. A blower with adjustable wind speed includes a body 1. A speed regulating device is connected to one side of the body 1. The speed regulating device includes a control sleeve 2, an adapter rod 3, a connecting pipe 4, an adapter hole 5, an adapter pipe 6, a mating rod 7, a mating sleeve 8, and a fixing pipe 9. The two ends of the control sleeve 2 are rotatably connected to the connecting pipe 4 and the fixing pipe 9, respectively. The adapter rod 3 is slidably disposed inside the adapter pipe 6. Multiple adapter holes 5 are formed on the outer wall of the adapter pipe 6. The adapter pipe 6 is disposed inside the connecting pipe 4. The mating rod 7 is fixedly connected to one end of the adapter rod 3. The mating sleeve 8 is movably sleeved on the outside of the mating rod 7 by a thread. The fixing pipe 9 is fixedly connected to one side of the body 1. A locking mechanism is provided on the outside of the connecting pipe 4. The locking mechanism includes a sliding sleeve 10, a relief groove 11, a movable block 12, a compression spring 13, a guide rod 14, a guide hole 15, and a connecting plate. 16. A horizontal plate 17, a limiting block 18, a linkage block 19, a connecting block 20, a movable plate 21, and a connecting spring 22. A sliding sleeve 10 is slidably disposed on the outside of the connecting pipe 4. A clearance groove 11 is opened on the movable plate 21. A movable block 12 is fixedly connected to one side of the movable plate 21. A compression spring 13 is sleeved on the outside of the guide rod 14. The guide rod 14 is fixedly connected to one side of the movable block 12. A guide hole 15 is opened in the connecting block 20. A connecting plate 16 is fixedly connected to one side of the sliding sleeve 10. Multiple horizontal plates 17 are fixedly installed on one side of the connecting plate 16. Multiple limiting blocks 18 are fixedly disposed on the outside of the connecting pipe 4. A linkage block 19 is disposed on one side of the control sleeve 2. A connecting block 20 is fixedly installed on the outside of the connecting pipe 4. A movable plate 21 is rotatably installed on the outside of the connecting pipe 4. The two ends of the connecting spring 22 are respectively connected to two adjacent linkage blocks 19.

[0032] The other end of the connecting pipe 4 is detachably connected to a blowpipe 23.

[0033] In this embodiment, when the wind speed needs to be adjusted according to the actual situation, the movable plate 21 is first rotated forward. The movable plate 21 drives the relief groove 11 to rotate forward. Then, the movable plate 21 drives the thrust bearing 25 installed on one side and the movable block 12 installed on the other side to rotate forward. Then, the movable block 12 drives the guide rod 14 set on one side to rotate forward along the guide hole 15 opened in the connecting block 20. Then, the movable block 12 and the connecting block 20 cooperate to compress the compression spring 13. When the compression spring 13 is compressed to the limit, the relief groove 11 just rotates to the position corresponding to the horizontal plate 17, and then pushes the sliding sleeve 10. The sliding sleeve 10 drives the inner side The slider 31 slides along the groove 30, and the sleeve 10 drives the horizontal plate 17 to slide via the connecting plate 16. The sleeve 10 and the thrust bearing 25 cooperate to compress the movable spring 24. When the movable spring 24 is compressed to its limit, the horizontal plate 17 closest to the sleeve 10 just passes through the clearance groove 11 and moves to the other side of the movable plate 21. Then the movable plate 21 is released, the compression spring 13 pushes the movable block 12 to rotate in the opposite direction and reset. Then the movable block 12 drives the movable plate 21 to rotate and reset. Then the movable plate 21 drives the clearance groove 11 and the thrust bearing 25 installed on one side to rotate in the opposite direction and reset. Then the clearance groove 11 will reset to a position where it is not in contact with the horizontal plate 10. At position 7, the connecting plate 16 and the horizontal plate 17 cooperate to limit the sliding sleeve 10 to one side of the movable plate 21. Then, the sliding sleeve 10 no longer limits the outer side of the linkage wheel 34. Then, the control sleeve 2 rotates forward, and the control sleeve 2 drives the limit rail 28 installed on one side to rotate forward. Then, the limit rail 28 drives the linkage block 19 to rotate forward through the cooperation with the limit groove 29. Then, the linkage block 19 drives the linkage wheel 34 to rotate, so that the linkage wheel 34 moves out from between the two limit blocks 18. Then, the linkage wheel 34 drives the linkage block 19 to move outward along the limit rail 28 and the limit groove 29, and causes the linkage block 19 to drive the connecting spring 22 to stretch outward. Simultaneously, the control sleeve 2 drives the mating sleeve 8 to rotate in the forward direction via the connecting rod. Since the mating sleeve 8 and the mating rod 7 are connected by threads, and the moving rail 26 and the moving groove 27 limit the adapter rod 3, the adapter rod 3 and the mating rod 7 will not rotate. Then, the mating rod 7 will slide along the moving rail 26 and the moving groove 27, thereby allowing the adapter rod 3 to slide in the adapter tube 6. Then, the number of adapter holes 5 blocked by the mating rod 7 is reduced, which increases the flow area at the corresponding position in the connecting tube 4, thereby changing the wind speed. When it is necessary to reduce the flow area at the corresponding position in the connecting tube 4, the control sleeve 2 can be rotated in the reverse direction.

[0034] Please refer to Figures 2-5 for a further embodiment of the overall device: a movable spring 24 is connected to one side of the sliding sleeve 10, and a thrust bearing 25 is detachably provided on one side of the movable plate 21. The other end of the movable spring 24 is connected to the thrust bearing 25.

[0035] Multiple movable rails 26 are fixedly installed inside the adapter tube 6, and multiple movable slots 27 are opened on the outside of the adapter rod 3. The movable slots 27 are adapted to the movable rails 26.

[0036] Multiple limit rails 28 are fixedly provided on one side of the control sleeve 2, and a limit groove 29 is opened in the linkage block 19, which is adapted to the limit rails 28.

[0037] Multiple grooves 30 are provided on the outer side of the connecting pipe 4, and multiple sliders 31 are fixedly provided on the inner side of the sliding sleeve 10, with the sliders 31 sliding in the grooves 30.

[0038] The adapter tube 6 has an adapter plate 32 on its outer side, and the mating sleeve 8 has multiple fixing rods 33 on its outer side. The outer wall of the mating sleeve 8 is fixedly connected to the outer wall of the control sleeve 2 through the fixing rods 33, and the outer wall of the adapter tube 6 is fixedly connected to the inner wall of the connecting tube 4 through the adapter plate 32.

[0039] A linkage wheel 34 is provided on one side of the linkage block 19, and the linkage wheel 34 is engaged between the two corresponding limiting blocks 18.

[0040] More specifically, once the wind speed is adjusted appropriately, the control sleeve 2 stops rotating, and the control sleeve 2, through the cooperation of the limiting rail 28 and the limiting groove 29, drives the linkage block 19 to rotate between the two corresponding limiting blocks 18. The linkage block 19 then drives the linkage wheel 34, which is mounted on one side, to rotate between the two corresponding limiting blocks 18. Then, the connecting spring 22 resets and pulls the linkage block 19 to slide inward along the limiting rail 28 and the limiting groove 29, causing the linkage block 19 to drive the linkage wheel 34 to engage with the two corresponding limiting blocks 18. Then, the movable plate 21 is rotated forward again, causing the movable plate 21 to drive the thrust bearing 25 installed on one side and the movable block 12 set on the other side to rotate forward. The movable plate 21 will also drive the relief groove 11 to rotate. Then, the movable block 12 will drive the guide rod 14 to slide along the guide hole 15 again, and the movable block 12 will cooperate with the connecting block 20 to compress the compression spring 13. When the relief groove 11 rotates to the position corresponding to the horizontal plate 17 again, the movable spring 24 pushes the sliding sleeve 10 to drive the slider 31 to slide along the sliding sleeve 15. The groove 30 slides back to its original position, and the sliding sleeve 10 drives the horizontal plate 17 to slide back to its original position via the connecting plate 16. After the movable spring 24 is fully reset, the other two horizontal plates 17 are located on both sides of the movable plate 21. Then the movable plate 21 is released, and the compression spring 13 pushes the movable block 12 to rotate and reset. Then the movable block 12 drives the guide rod 14 to slide back to its original position along the guide hole 15. The movable block 12 drives the clearance groove 11 to rotate and reset to a position that does not correspond to the horizontal plate 17 via the movable plate 21. Then the connecting plate The sliding sleeve 10 is limited and supported by the two horizontal plates 17. The sliding sleeve 10 is limited by the slider 31 and the sliding groove 30, so that the sliding sleeve 10 cannot slide. Then, the inner wall of the sliding sleeve 10 limits the outer wall of the linkage wheel 34, so that the linkage block 19 and the linkage block 19 cannot slide outward along the limit rail 28 and the limit groove 29. This locks the control sleeve 2 and prevents the control sleeve 2 from rotating, thus ensuring the overall structural stability after the wind speed is adjusted.

[0041] In summary, during the use or operation of the overall equipment: when the wind speed needs to be adjusted according to the actual situation, firstly, the movable plate 21 is rotated forward. The movable plate 21 drives the relief groove 11 to rotate forward. Then, the movable plate 21 drives the thrust bearing 25 installed on one side and the movable block 12 installed on the other side to rotate forward. Then, the movable block 12 drives the guide rod 14 set on one side to rotate forward along the guide hole 15 opened in the connecting block 20. Then, the movable block 12 and the connecting block 20 cooperate to compress the compression spring 13. When the compression spring 13 is compressed to its limit, the relief groove 11 just rotates to the position corresponding to the horizontal plate 17, and then pushes the sliding sleeve 10. The sleeve 10 drives the inner slider 31 to slide along the slide groove 30, and the sleeve 10 drives the horizontal plate 17 to slide through the connecting plate 16. The sleeve 10 and the thrust bearing 25 cooperate to compress the movable spring 24. When the movable spring 24 is compressed to its limit, the horizontal plate 17 closest to the sleeve 10 just passes through the relief groove 11 and moves to the other side of the movable plate 21. Then the movable plate 21 is released, the compression spring 13 pushes the movable block 12 to rotate in the opposite direction and reset. Then the movable block 12 drives the movable plate 21 to rotate and reset. Then the movable plate 21 drives the relief groove 11 and the thrust bearing 25 installed on one side to rotate in the opposite direction and reset. Then the relief groove 11 will reset to its original position. The sliding sleeve 10 is positioned not corresponding to the horizontal plate 17. The connecting plate 16 and the horizontal plate 17 then cooperate to limit the sliding sleeve 10 to one side of the movable plate 21. The sliding sleeve 10 no longer limits the outer side of the linkage wheel 34. The control sleeve 2 rotates forward, causing the limiting rail 28 installed on one side to rotate forward. The limiting rail 28, through its cooperation with the limiting groove 29, causes the linkage block 19 to rotate forward. The linkage block 19 then drives the linkage wheel 34 to rotate, causing the linkage wheel 34 to move outward from between the two limiting blocks 18. The linkage wheel 34 then drives the linkage block 19 to move outward along the limiting rail 28 and the limiting groove 29, causing the linkage block 19 to drive the connecting spring 22 outward. During the stretching process, the control sleeve 2 drives the mating sleeve 8 to rotate in the forward direction via the connecting rod. Since the mating sleeve 8 and the mating rod 7 are connected by threads, and the moving rail 26 and the moving groove 27 limit the adapter rod 3, the adapter rod 3 and the mating rod 7 will not rotate. Then, the mating rod 7 will slide along the moving rail 26 and the moving groove 27, thereby allowing the adapter rod 3 to slide in the adapter tube 6. Then, the number of adapter holes 5 blocked by the mating rod 7 is reduced, which increases the flow area at the corresponding position in the connecting tube 4, thereby changing the wind speed. When it is necessary to reduce the flow area at the corresponding position in the connecting tube 4, the control sleeve 2 can be rotated in the reverse direction.

[0042] Once the wind speed is adjusted appropriately, stop rotating the control sleeve 2. The control sleeve 2, through the cooperation of the limiting rail 28 and the limiting groove 29, drives the linkage block 19 to rotate between the two corresponding limiting blocks 18. The linkage block 19 then drives the linkage wheel 34, which is mounted on one side, to rotate between the two corresponding limiting blocks 18. Then, the connecting spring 22 resets, pulling the linkage block 19 inward along the limiting rail 28 and the limiting groove 29, causing the linkage block 19 to drive the linkage wheel 34 to engage between the two corresponding limiting blocks 18. Then, the movable plate 21 is rotated forward again, causing the thrust bearing 25 installed on one side and the movable block 12 set on the other side to rotate forward. The movable plate 21 will also cause the relief groove 11 to rotate. Then, the movable block 12 will again drive the guide rod 14 to slide along the guide hole 15, and the movable block 12 will again cooperate with the connecting block 20 to compress the compression spring 13. When the relief groove 11 rotates to the position corresponding to the horizontal plate 17, the movable spring 24 pushes the sliding sleeve 10 to drive the slider 31 to slide and reset along the sliding groove 30. The sliding sleeve 10 drives the horizontal plate 17 to slide and reset through the connecting plate 16. When the movable spring 24 is fully reset, the other two horizontal plates 17 are exactly located on both sides of the movable plate 21. Then, the movable plate 21 is released, and the compression spring 13 pushes the movable block 12 to rotate and reset. Then, the movable block 12 drives the guide rod 14 to slide and reset along the guide hole 15. The movable block 12 drives the relief groove 11 to rotate and reset to a position not corresponding to the horizontal plate 17 through the movable plate 21. Then, the connecting plate 16... The 6 and two horizontal plates 17 work together to limit and support the sliding sleeve 10. Together with the slider 31 and the sliding groove 30, the sliding sleeve 10 is limited and cannot slide. Then, the inner wall of the sliding sleeve 10 limits the outer wall of the linkage wheel 34, so that the linkage block 19 and the linkage block 19 cannot slide outward along the limit rail 28 and the limit groove 29. This locks the control sleeve 2 and prevents the control sleeve 2 from rotating, thus ensuring the overall structural stability after wind speed adjustment.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
