[0002] A self-lubricating oilless blower is a type of blower that can achieve self-lubrication without the need for additional lubricating oil during operation. Similar to ordinary blowers, it relies on the rotation of the impeller to drive the gas, giving the gas energy, thereby achieving gas delivery and pressurization. Its self-lubricating principle is mainly achieved through special materials and surface treatment technology.

[0003] The casing of existing blowers is generally fixed by tightening multiple bolts. During later use, when it is necessary to clean or repair the blades, the staff needs to use tools to tighten each bolt one by one. This is not only cumbersome, but the individual bolts are also very easy to fall off or be lost, which will affect the later installation.

[0004] Therefore, it is necessary to provide a new self-lubricating oilless blower to solve the above-mentioned technical problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 6 The present invention provides a self-lubricating oil-free blower, which includes a base plate 1.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 6A base plate 1 has a supporting back plate 11, and a motor 12 is mounted on the supporting back plate 11. The output end of the motor 12 passes through the supporting back plate 11 and has a drive rod 13. The drive rod 13 is fitted with a blade 2, and the blade 2 is fitted with a housing 3. A snap-fit ​​assembly 4 is provided on the side of the supporting back plate 11 away from the blade 2. Multiple evenly distributed insertion holes 111 are opened inside the supporting back plate 11. Multiple evenly distributed insertion rods 32 are provided on the side wall of the housing 3. The outer wall of the insertion rods 32 abuts against and slides against the inner wall of the insertion holes 111, and the outer wall of the insertion rods 32 extends to the side of the supporting back plate 11 near the motor 12. A limiting groove 321 is provided; the snap-fit ​​assembly 4 includes a linkage frame 41, two linkage frames 41 are provided and symmetrically distributed on the support back plate 11, the end of the linkage frame 41 is provided with a locking block 411, the outer wall of the locking block 411 abuts against the inner wall of the limiting groove 321, one side of the side wall of the two linkage frames 41 is provided with the same slidingly connected guide rod 42, and the guide rod 42 is mounted on the support back plate 11, the other side of the side wall of the two linkage frames 41 is provided with the same threaded rotating rod 43, the thread direction of the thread structure on both sides of the outer wall of the rotating rod 43 is opposite, and the rotating rod 43 is rotatably mounted on the support back plate 11.

[0029] It should be noted that the snap-fit ​​limiting method is used to fix the outer shell 3 to the support back plate 11. When the internal blade 2 needs to be disassembled for cleaning and maintenance, the snap-fit ​​component 4 can be directly moved out of the limiting groove 321 to release the limiting of the outer shell 3. The outer shell 3 and the blade 2 can then be taken out one by one. Compared with the method of tightening multiple bolts, it is more flexible to operate without the need for additional tools. At the same time, it can also reduce the inconvenience caused by the loss or falling of individual bolts during operation.

[0030] Since the thread direction between the rotating rod 43 and the corresponding linkage frame 41 is opposite, when the rotating rod 43 rotates, it can smoothly drive the linkage rods on both sides to move relative to each other or in opposite directions, thereby realizing the synchronous drive of the locking block 411 at the end of the linkage rod, so that it synchronously abuts against the limiting groove 321 or moves out of the limiting groove 321.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 6 The outer casing 3 has a connected exhaust pipe 31 on its side wall, and the insertion rod 32 and the insertion hole 111 are distributed in a ring around the center of the supporting back plate 11.

[0032] It should be noted that since the multiple sockets 111 and the plug rods 32 are arranged in a ring, the housing 3 can be flexibly rotated as needed during installation. This allows the housing 3 to smoothly drive the exhaust pipe 31 on the side wall to rotate, and the exhaust port of the exhaust outlet to move smoothly to the required angle. Therefore, this can help improve the flexibility of the device in later use.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 6 A sleeve 21 is provided on the side wall of the blade 2. The inner wall of the sleeve 21 abuts against and is slidably connected to the outer wall of the drive rod 13. An adjusting rod 35 is provided inside the outer casing 3. A retaining sleeve 351 is provided at one end of the adjusting rod 35 near the drive rod 13. The inner wall of the retaining sleeve 351 abuts against the end of the drive rod 13. The end of the retaining sleeve 351 abuts against the end of the sleeve 21. The drive rod 13 is a rectangular rod. A connecting sleeve 33 is provided on the side wall of the outer casing 3. A threaded protective sleeve 34 is provided outside the connecting sleeve 33. The protective sleeve 34 is located outside the adjusting rod 35.

[0034] It should be noted that by setting the drive rod 13 as a rectangular structure, when the sleeve 21 is fitted over the drive rod 13, the working motor 12 will smoothly drive the blade 2 to rotate through the drive rod 13. Through the abutment of the sleeve 21 and the clamp 351, the clamp 351 can prevent the blade 2 from sliding randomly on the drive rod 13 when the blade 2 rotates, thus making the rotation of the blade 2 more stable. The protective sleeve 34 located outside the adjusting rod 35 can cover and protect the protruding adjusting rod 35 during use.

[0035] In the embodiments of this utility model, please refer to Figures 1 to 6 A transition rod 44 is provided on the side wall of one side linkage frame 41. Two evenly distributed limiting holes 441 are opened inside the transition rod 44. A support frame 5 is provided on the outer wall of the support back plate 11 opposite to the transition rod 44. The inner wall of the support frame 5 abuts against and slides with the outer wall of the transition rod 44. A slidingly connected limiting rod 51 is inserted inside the support frame 5. The outer wall of the limiting rod 51 abuts against and slides with the inner wall of the limiting hole 441. A limiting spring 52 is provided between the limiting rod 51 and the support frame 5.

[0036] It should be noted that when the linkage frame 41 drives the locking block 411 to abut against the limiting groove 321, completing the limiting of the installation of the outer shell 3, the adapter rod 44 located on the side wall of the linkage frame 41 drives the limiting hole 441 to move to the opposite direction of the limiting hole 441. At this time, when the operator releases the pull on the limiting rod 51, the limiting spring 52 will drive the limiting rod 51 to move closer to the limiting hole 441 through its own force until it is inserted into the limiting hole 441, thereby realizing the limiting of the adapter rod 44. Therefore, it can avoid the vibration of the device during operation during later use, which would cause the rotating rod 43 to rotate and cause the limiting of the outer shell 3 to become loose.

[0037] The working principle of the self-lubricating oilless blower provided by this utility model is as follows:

[0038] When using this device, the operator can first remove the blade 2 and put the sleeve 21 in the blade 2 on the outside of the drive rod 13. Then the outer shell 3 can be removed and put on the outside of the blade 2. During this process, the outer shell 3 can be rotated according to the actual use needs, so as to drive the external exhaust pipe 31 to rotate synchronously. Therefore, the air outlet angle of the exhaust port at the end of the exhaust pipe 31 can be adjusted. Then the insertion rod 32 on the side wall of the outer shell 3 can be inserted into the insertion hole 111 on the support back plate 11.

[0039] During this process, the operator can move the adjusting rod 35 to rotate the end of the retaining tube 351, so that the inner wall of the retaining tube 351 is at the same angle as the inner wall of the drive rod 13, and the retaining tube 351 is smoothly inserted into the outer wall of the drive rod 13 until the end of the retaining tube 351 abuts against the end of the sleeve 21 in the blade 2. At this time, the rotating tube can be controlled to rotate. The rotating tube will drive the linkage frame 41 on both sides to move relative to each other on the outer wall of the guide rod 42 through the thread structure with opposite thread directions on both sides of the outer wall until the retaining block 411 at its end abuts against the limiting groove 321 on the outer wall of the insertion rod 32, thus completing the limiting of the installation of the outer shell 3.

[0040] When the staff needs to disassemble, repair and clean the blade 2 later, they can control the rotating cylinder to rotate in the opposite direction, so that it can drive the locking block 411 to move out of the limiting groove 321 through the linkage frame 41. Then the outer shell 3 and the blade 2 can be taken out and disassembled in turn without the need to use tools to repeatedly tighten multiple bolts. At the same time, it can also reduce the inconvenience caused by the loss or falling of individual bolts during the operation.

[0041] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
