It generally includes a series commutator motor, a centrifugal fan, a dust filter (bag) and dust suction accessories. Generally, the wires of a vacuum cleaner are longer and are equipped with a wire-reeling device to prevent the wires from getting tangled when the vacuum cleaner is in use.

[0003] With reference to the utility model patent with authorized patent number CN211933890U, a wire reel structure for an electric vacuum cleaner is proposed, comprising a motor, a wire reel and a gear set, a power cord is wound on the wire reel, the gear set comprises a driving wheel and a driven wheel, the driving wheel is mounted on the motor and rotates under the drive of the motor, the driven wheel rotates under the drive of the driving wheel, and the driven wheel is transmission-connected to the wire reel and drives the wire reel to rotate.

[0004] The above patent has the following defects in use: when the starting motor drives the winding wheel to reel in the wire, there is no tensioning structure design when reeling in the wire, which easily causes the wire reeled on the winding wheel to loosen. When the winding wheel is reeling in or unreeling, the loose wire may get stuck on the wheel, affecting the normal use function and having low practicality. For this reason, we propose a vacuum cleaner cord reel with a tensioning wheel to solve the above defects. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A vacuum cleaner cord reel with a tight wheel comprises a vacuum cleaner winding box 1, the vacuum cleaner winding box 1 is a disc cavity structure, a wire take-up port 2 is installed on the front side of the vacuum cleaner winding box 1, and the wire take-up port 2 extends to the inside of the vacuum cleaner winding box 1, a cover shell 4 is fixedly installed on the left side of the vacuum cleaner winding box 1, and a motor 5 is arranged inside the cover shell 4, the output end of the motor 5 rotates through the inside of the vacuum cleaner winding box 1 and a rotating shaft 6 is fixedly installed on the output end of the motor 5, and the right end of the rotating shaft 6 is rotatably installed on the inner wall of the vacuum cleaner winding box 1 and the rotating shaft 6 is fixedly mounted with a winding drum 7, on which a conducting wire 3 is wound, the conducting wire 3 extends to the outside of the wire taking-up port 2, the inner diameter of the wire taking-up port 2 is larger than the outer diameter of the conducting wire 3, a tightening wheel mechanism is arranged at the front side of the winding drum 7, the tightening wheel mechanism comprises a rotating rod 8, the rotating rod 8 is rotatably mounted on the vacuum cleaner winding box 1 and an internal threaded cylinder 10 is screwed at the lower end of the rotating rod 8, an axle seat 13 is fixedly mounted at the bottom of the internal threaded cylinder 10, a first guide roller 14 is rotatably mounted on the side of the axle seat 13, and a second guide roller 15 is rotatably mounted on the inner side of the wire taking-up port 2.

[0024] By the above structure, the motor 5 is started to rotate, and the output end of the motor 5 drives the rotating shaft 6 and the winding drum 7 fixedly installed on the rotating shaft 6 to rotate, so as to reel the wire 3. The wire 3 passes through the second guide roller 15 and the first guide roller 14 in sequence, and is finally wound on the winding drum 7. When the wire 3 passes through the second guide roller 15 and the first guide roller 14, two friction chamfering effects are respectively generated. The chamfer size is the outer diameter of the second guide roller 15 and the first guide roller 14, respectively, and the chamfer length is the contact length between the wire 3 and the outer side of the second guide roller 15 and the first guide roller 14, respectively. The internal threaded barrel 10 can be driven to move up and down by rotating the rotating rod 8, thereby changing the upper and lower positions of the first guide roller 14 at the bottom of the internal threaded barrel 10. When the first guide roller 14 moves upward, the friction chamfer length between the first guide roller 14 and the second guide roller 15 and the wire 3 increases, thereby increasing the winding tension of the wire 3. Conversely, when the first guide roller 14 moves downward, the winding tension of the wire 3 is reduced.

[0025] In this embodiment, a rotating seat 9 is fixedly mounted on the rotating rod 8, and the rotating seat 9 is a hexagonal anti-slip seat.

[0026] Through the above structure, the rotary seat 9 is set as a hexagonal anti-skid seat, so that when the rotary seat 9 is rotated to rotate the rotating rod 8, it is not easy to slip, making the adjustment process more sensitive.

[0027] In this embodiment, heat dissipation holes 41 are evenly distributed on the side of the cover shell 4 , and a rotary cover 42 is screwed at the end of the cover shell 4 .

[0028] Through the above structure, the heat dissipation holes 41 dissipate the working heat of the motor 5 to ensure the normal working temperature of the motor 5. The design of the rotary cover 42 makes it easy to open the cover 4 to inspect the motor 5.

[0029] In this embodiment, a plurality of ear seats 51 are fixedly connected to the bottom of the motor 5 , and the ear seats 51 are screwed and installed on the side wall of the vacuum cleaner reel box 1 .

[0030] Through the above structure, the motor 5 is fixed by screw connection, which is convenient for replacement and maintenance of the motor 5 at a later time.

[0031] In this embodiment, a guide block 11 is fixedly connected to the side of the internal threaded tube 10, a through hole is opened on the inner side of the guide block 11, a guide column 12 is slidably connected to the inner side of the through hole, and the upper end of the guide column 12 is fixedly installed on the inner wall of the vacuum cleaner winding box 1, the through hole is a square hole, the guide column 12 is a rectangular structural column, and the cross-sectional size of the guide column 12 is adapted to the square hole.

[0032] Through the above structure, the square hole has the characteristic of limiting the rotational freedom. Since the internal threaded tube 10 and the rotating rod 8 are in a threaded connection, the rotating rod 8 drives the internal threaded tube 10 to move up and down by rotating and utilizing the threaded engagement. Here, the guide column 12 is connected to the square hole through a sliding relationship, thereby limiting the rotational driving force caused by the thread side pressure during the threaded drive, so that the movement direction of the internal threaded tube 10 is along the vertical direction of the guide column 12.

[0033] In the utility model, when in use, the motor 5 is started to rotate, and the output end of the motor 5 drives the rotating shaft 6 to rotate, then the winding drum 7 fixed on the rotating shaft 6 rotates, and the wire 3 is wound. Under the action of the winding drum 7, the wire 3 passes through the wire take-up port 2 and passes through the second guide roller 15 and the first guide roller 14 in turn, and is finally wound on the winding drum 7. When it is necessary to increase the winding tension of the wire 3, the rotating seat 9 can be rotated to drive the rotating rod 8 to rotate, and the first guide roller 14 can be driven to move upward. On the contrary, the rotating seat 9 is rotated in the opposite direction to drive the first guide roller 14 to move downward, so as to reduce the winding tension of the wire 3. The above is the working process and principle of the utility model. The utility model increases the winding tension of the wire 3 when winding by setting a tight wheel mechanism, makes the wire 3 wound on the winding drum 7 more compact, avoids the occurrence of winding slack on the winding drum 7, avoids the wheel jam failure of the winding drum 7, and improves the practicality. In addition, the winding tension can be flexibly adjusted by rotating the rotating rod 8, which further improves the practicality.

[0034] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
