In order to facilitate air suction, the air inlet fan blade 32 can be designed into a gull-wing shape, and it should be noted that, although the air inlet fan blade 32 in the prior art is designed into a gull-wing structure, the air inlet fan blade can also be designed into a structure with a thick middle part and two thin sides, but the yarn can only be ground by friction, and the cutting of the yarn is difficult to realize, in order to solve the above problems, the following scheme can be adopted, wherein the outer side edge of the air inlet fan blade 32 is provided with a knife tip 321, the knife tip 321 abuts against the inner side wall of the knife abutting groove 331, the ground yarn is changed into the cutting of the yarn by the propping of the knife tip 321 and the knife abutting groove 331, so that the yarn is conveniently cut, the knife tip 321 is arc-shaped, the contact length between the knife tip 321 and the inner side wall of the knife abutting groove 331 is longer, the cutting effect of the yarn by the knife tip 321 is better, and the knife tip 321 and the knife abutting groove 331 are coaxially arranged, so that the cutting stability of the knife tip 321 to the yarn is ensured; specifically, the yarn is pushed into the knife abutting groove 331, and then the yarn is cut by the rotating knife edge 321.
In order to realize the pushing of the thread material, the upper surface of the air inlet fan blade 32 is provided with a sliding groove 322 extending axially, and the width of the sliding groove 322 gradually increases from the air inlet shaft 31 to the air inlet sleeve 33, so that the sliding groove 322 extends from the air inlet shaft 31 to the air inlet sleeve 33, and slides from the air inlet shaft 31 to the air inlet sleeve 33 along the sliding groove 322 through the pushing part 5 to realize the pushing of the thread material.
The structure of the specific pushing portion 5 is as follows, the pushing portion 5 includes a pushing block 51 slidably connected in the sliding groove 322, specifically, a guide block 52 is arranged at the bottom of the pushing block 51, the guide block 52 is inserted in the sliding groove 322, in the rotation process of the air inlet fan blade 32, the guide block 52 slides towards the air inlet sleeve 33 from the air inlet shaft 31 under the action of centrifugal force, the guide block 52 slides along the sliding groove 322 to realize the sliding of the pushing block 51, meanwhile, the width of the pushing block 51 is greater than that of the guide block 52, and then the pushing block 51 is erected on the surface of the air inlet fan blade 32, and dust on the surface of the air inlet fan blade 32 can be scraped in the sliding process of the pushing block 51, and because the surface of the air inlet fan blade 32 is a curved surface, so that the bottom surface of the pushing block 51 is attached to the air inlet fan blade 32, the bottom of the pushing block 51 can be designed to be flexible, that the bottom of the pushing block 51 can be deformed, and then the pushing block 51 can keep in contact with the upper surface of the air inlet fan blade 32, thereby achieving a better dust scraping effect on the air inlet fan blade 32.
Because the sliding groove 322 is set to be in a shape that one end close to the air inlet sleeve 33 is wide and one end close to the air inlet shaft 31 is narrow, in order to ensure that the guide block 52 can slide in the sliding groove 322, a scheme needs to be designed that the sliding groove 322 is set to be in an inverted "T" shape, namely the sliding groove 322 is composed of a structure that the upper part is thin and the lower part is thick; two tightening components 53 are arranged at the bottom of the pushing block 51 in a mirror image manner, the two tightening components 53 are respectively positioned at two sides of the guide block 52, the tightening components 53 extend oppositely, and the tightening components 53 are pressed against the inner side wall of the sliding groove 322; the puller component 53 comprises a puller spring 531, one end of the puller spring 531 is fixedly connected with a guide block 52 at the bottom of the pushing block 51, a puller block 532 is fixed at the other end of the puller spring 531, the puller block 532 is abutted against the side wall of the wide part in the sliding groove 322, the guide block 52 can be kept clamped in the sliding groove 322 through the resilience force of the puller spring 531, the puller spring 531 is in a stretching state in the sliding process of the pushing block 51 from the air inlet shaft 31 to the knife abutting groove 331, and at the moment, the friction force between the pushing block 51 and the sliding groove 322 is slowly smaller, so that the thread is pushed more easily, and the thread is cut conveniently; when pushing away piece 51 and being pulled back to air inlet shaft 31 from tool groove 331 of keeping against, push up tight spring 531 and constantly compress, push up the continuous increase of frictional force between tight piece 532 and the sliding tray 322, and then improved the sliding stability who pushes away piece 51, locking portion 4 is better to the locking effect who pushes away piece 51 this moment, avoids the condition that the dust absorption during operation pushed the unexpected percussion of piece 51.
In this embodiment, since the width of the sliding groove 322 gradually increases from the air inlet shaft 31 to the knife abutting groove 331, the two side walls of the sliding groove 322 are not parallel to each other, but are inclined in a trapezoidal shape, in order to achieve a good tightening effect between the tightening block 532 and the inner side wall of the sliding groove 322,
in order to realize that the pushing block 51 automatically returns to the initial position after pushing the thread, a pushing spring 54 is fixed on the inner side wall of the sliding groove 322, the pushing spring 54 is located at one side close to the air inlet shaft 31, the pushing spring 54 is also fixedly connected with the pushing block 51, the pushing block 51 pushes the thread and stretches the pushing spring 54, after the thread is cut, the motor body is stopped to stop the rotation of the air inlet fan blade 32, and the pushing spring 54 rebounds to pull the pushing block 51 back to the initial position.
In order to realize the locking of the pushing block 51, a locking groove 511 is formed at the top of the pushing block 51, and the locking groove 511 is matched with the locking part 4; after the locking part 4 releases the pushing block 51, the pushing block 51 can slide while the air inlet fan blade 32 rotates, and after the pushing spring 54 pulls the pushing block 51 back to the initial position, the locking part 4 can be inserted into the locking groove 511 to lock the pushing block 51.
It should be noted that, the more the wires wound on the air inlet fan blade 32, the greater the resistance of the wires to the push block 51, and when the resistance of the wires to the push block 51 is greater than the centrifugal force of the air inlet fan blade 32 to the push block 51, the push block 51 cannot slide along the sliding groove 322, and thus the cleaning effect on the air inlet fan blade 32 cannot be achieved, in order to solve the above problem, a scheme is required to be designed, in which a push knife 55 is disposed on the push block 51, the push knife 55 extends along the abutting groove 331, the push knife 55 has a knife edge 551, and the knife edge 551 of the push knife 55 faces the abutting groove 331, the push knife 55 is fixed on the upper end surface of the push block 51, and when the air inlet fan blade 32 rotates, the wires can be cut off in advance by the push knife 55, so that the push block 51 can slide along the sliding groove 322, and the situation that the push block 51 is jammed is avoided by such a design, and the push block 51 can clean the surface of the air inlet fan blade 32 is ensured.
It should be noted that, due to the existence of the pushing block 51, a gap exists between the push broach 55 and the air intake shaft 31, and if the thread material is wound in the gap, the pushing block 51 cannot push the thread material in the region, in order to solve the above problem, it is necessary to design a scheme that the push broach 55 is obliquely arranged, and the specific push broach 55 is inclined toward the air intake shaft 31, so that the thread material wound on the push broach 55 will also deviate toward the knife abutting groove 331 along the push broach 55, so that the push broach 55 can pre-cut the thread material, and at the same time, when the thread material is wound on the air intake fan blade 32, the thread material can be prevented from deviating toward the air intake shaft 31 due to the existence of the push broach 55.
In order to realize the locking of the pushing block 51, a releasing groove 311 is formed at the end of the air inlet shaft 31, and the releasing groove 311 is positioned at one side close to the suction inlet of the dust collector; the structure of the locking part 4 is as follows, the locking part 4 comprises a locking spring 41 with one end fixed in the releasing groove 311 and a locking disc body 42 fixed at the other end of the locking spring 41, the diameter of the locking disc body 42 is larger than that of the air inlet shaft 31, a plurality of locking rods 43 are fixed at the bottom of the locking disc body 42, each locking rod 43 surrounds the outer ring of the air inlet shaft 31, the locking rods 43 extend from top to bottom, and the locking rods 43 are matched with the locking grooves 511; when the locking spring 41 is not compressed, the upper end surface of the locking disc body 42 protrudes out of the upper end surface of the air inlet sleeve 33, the locking spring 41 can be compressed by pressing the locking disc body 42, but the locking disc body 42 can only be pressed until the upper end surface of the locking disc body 42 is flush with the upper end surface of the air inlet sleeve 33 at most; when the housing 2 and the hood 1 are installed, that is, when the air inlet 21 corresponds to the suction inlet of the vacuum cleaner, the locking disc body 42 is pressed by the frame of the suction inlet in the vacuum cleaner, the locking disc body 42 compresses the locking spring 41, and when the locking disc body 42 is pressed until the upper end surface of the locking disc body 42 is flush with the upper end surface of the air inlet sleeve 33, the locking rod 43 can be automatically inserted into the locking groove 511; when the casing 2 and the hood 1 are disassembled, the suction inlet of the dust collector loosens the locking disc body 42, the locking spring 41 rebounds to push the locking disc body 42 to protrude out of the upper end surface of the air inlet sleeve 33, and the locking disc body 42 drives the locking rod 43 to be disengaged from the locking groove 511, so that the pushing block 51 is loosened.
It should be noted that after long-term use, the restoring capability of the pushing spring 54 is reduced, and when the pushing block 51 is pulled back by the pushing spring 54, the pushing block 51 may not return to the initial position, that is, the position of the locking rod 43 corresponding to the locking groove 511, that is, the locking rod 43 is only inserted on the upper end surface of the pushing block 51 and is not inserted into the locking groove 511, and thus cannot lock the pushing block 51, in order to solve the above problem, it is necessary to design a scheme that the upper end surface of the pushing block 51 is provided with a guide surface 512, the guide surface 512 is obliquely arranged, the push knife 55 is fixed on the guide surface 512, the thickness of the pushing block 51 is gradually reduced from the air inlet shaft 31 to the abutting groove 331, when the locking disc body 42 is pressed to lock the pushing block 51 by the locking rod 43, the bottom of the locking rod 43 is firstly contacted with the guide surface 512, and the locking rod 43 can slide into the locking groove 511 along the guide surface 512, so as to ensure that the locking rod 43 can lock the pushing block 51.
Example two
The other parts are the same as those of the first embodiment, except that the second embodiment also provides a working method of a dust collector motor, wherein the structure of the dust collector motor is the same as that of the first embodiment, and the description is omitted here.
Further, when the hood 1 and the casing 2 are removed, the locking spring 41 rebounds to push the upper end surface of the locking disc body 42 to protrude out of the upper end surface of the air inlet sleeve 33, and then the locking rod 43 is disengaged from the locking groove 511; the motor body rotates to drive the air inlet shaft 31 to rotate, so that the air inlet fan blade 32 rotates, and the pushing block 51 pushes the thread wound on the air inlet fan blade 32 to the knife abutting groove 331; the wire material is pre-cut by the push broach 55 and then cut by the tool nose 321; pausing the motor body, and pulling back the pushing block 51 by the pushing spring 54; mounting the hood 1 and the cabinet 2, sliding along the guide surface 512 by the locking lever 43 and inserting into the locking groove 511; the dust collection work is carried out through the rotation of the motor body.
