Description
Technical Field
[0001] The utility model relates to the technical field of vacuum cleaner equipment, in particular to a vacuum cleaner cord reel based on double reels. Background Art
[0002] The vacuum cleaner rotates at high speed through the electric motor, sucking air from the suction port, creating a certain vacuum in the dust box. The dust enters the dust filter bag in the dust box through the floor brush, connecting pipe, handle, hose, and main suction pipe. The dust is retained in the dust filter bag. The filtered air passes through a layer of filter and enters the electric motor. This layer of filter is a protective barrier to prevent the dust bag from breaking and being sucked into the electric motor. The air entering the electric motor flows out through the electric motor. Due to the continuous wear of the carbon brush during the operation of the electric motor, another filter is added before flowing out of the vacuum cleaner.
[0003] Vacuum cleaners are generally equipped with a wire-winding device during use. Existing wire-winding devices generally adopt a single-drum wire-winding design. Some use a clockwork spring as the winding power, and some use an electric motor as the winding power. The single-drum winding wire length has certain limitations. Compared with the double-drum winding method, it has the disadvantages of shorter winding length and low winding efficiency. For this reason, we propose a vacuum cleaner cord reel based on a double-drum. Utility Model Content
[0004] The utility model aims to solve the shortcomings of the prior art and proposes a vacuum cleaner cord reel based on double reels.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0014] In the utility model, a vacuum cleaner cord reel based on a double reel is described, and the first rotating shaft can be driven to rotate by starting the electric motor, and the first rotating shaft drives the first reel fixed on the outer side thereof to rotate. Since a planetary gear set is meshed between the first rotating shaft and the second reel, under the meshing transmission action, the second reel rotates in the opposite direction to the first rotating shaft. Therefore, under the drive of the electric motor, the first reel and the second reel rotate in the opposite direction. Since a power line segment is wound on the first reel and the power line segment extends to the first line outlet on the front side of the vacuum cleaner cord reel box, the second reel rotates in the opposite direction. A connecting wire segment is wound on the reel and extends to a second wire outlet on the rear side of the vacuum cleaner winding box, and the power wire segment and the connecting wire segment are wound in opposite directions on the first reel and the second reel. Although the first reel and the second reel turn in opposite directions, the first reel and the second reel simultaneously perform wire release or wire winding operations, thereby improving wire winding and release efficiency. In addition, through the double-reel design, the winding length of the wire inside the vacuum cleaner winding box is increased, and the overall extendable length of the wire is increased, thereby expanding the working radius of the vacuum cleaner and enhancing practical performance.

The first drum and the second drum are arranged to perform wire release or wire reeling work synchronously, thereby improving the wire reeling and releasing efficiency. The double-drum design increases the winding length of the wire inside the wire reel box of the vacuum cleaner, increases the overall extendable length of the wire, thereby expanding the working radius of the vacuum cleaner and enhancing the practical performance.

DETAILED DESCRIPTION
[0020] 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.

The middle part of the first rotating shaft 11 is rotatably sleeved with a collar 16, and the collar 16 is fixedly mounted on the inner wall of the vacuum cleaner winding box 1 through a connecting piece. Metal rings 18 are installed on both sides of the collar 16 in communication. The conductor 5 includes a power line segment 51 and a connecting line segment 52. The power line segment 51 is wound on the first reel 12, and the power line segment 51 extends to the outside of the first outlet 3. The connecting line segment 52 is wound on the second reel 13, and the connecting line segment 52 extends to the outside of the second outlet 4. The winding directions of the power line segment 51 and the connecting line segment 52 are opposite. The power line segment 51 and the connecting line segment 52 are both connected and mounted with a conducting brush 17, which is symmetrically distributed along the collar 16 and is in electrical contact with the metal ring 18.
[0022] Through the above structure, the electric motor 10 is started to drive the first rotating shaft 11 to rotate, and the first rotating shaft 11 drives the first reel 12 fixed on the outside to rotate. Since the planetary gear set 14 is meshed between the first rotating shaft 11 and the second reel 13, under the meshing transmission, the second reel 13 rotates in the opposite direction to the first rotating shaft 11. Then, driven by the electric motor 10, the first reel 12 and the second reel 13 rotate in opposite directions, but the power line segment 51 and the connecting line segment 52 are wound around the first reel 12 and the second reel 13 in opposite directions.

[0024] Through the above structure, a plurality of balls are arranged between the collar 16 and the first rotating shaft 11, which reduces the friction loss between the collar 16 and the first rotating shaft 11 when they rotate relative to each other, thereby increasing the service life of the equipment components.
[0025] In this embodiment, heat dissipation holes are provided on the outer side of the housing 7 .
[0026] Through the above structure, the heat dissipation holes opened on the machine compartment 7, when the electric motor 10 generates heat in the electric motor body during operation, the heat is discharged through the heat dissipation holes, maintaining the normal working temperature of the electric motor 10, and improving the protection of its working stability.
[0027] In this embodiment, a stiffening rib is provided at the connection between the second rotating shaft 15 and the inner wall of the vacuum cleaner winding box 1 .
[0028] Through the above structure, the provision of the stiffening ribs strengthens the connection strength of the connection between the side end of the second rotating shaft 15 and the inner wall of the vacuum cleaner winding box 1 , thereby ensuring the stability of the second rotating shaft 15 .
[0029] In this embodiment, the button 9 includes a line-reeling button and a line-releasing button.
[0030] In the utility model, when in use, the electric motor 10 is started to rotate, and the first rotating shaft 11 is driven to rotate by rotating the output end, and the first reel 12 fixedly installed on the outside of the first rotating shaft 11 is driven to rotate synchronously, and the second reel 13 mounted on the outside of the first rotating shaft 11, due to the planetary gear set 14 installed between it and the first rotating shaft 11, the second reel 13 rotates in the opposite direction to the first rotating shaft 11 according to the meshing transmission effect, and at the same time, the power line segment 51 and the connecting line segment 52 are wound in opposite directions on the first reel 12 and the second reel 13, and the first reel 12 and the second reel 13 perform the work of releasing or reeling in synchronously. When it is necessary to reel in the line, just press the reeling button on the button 9, and when it is necessary to release the line, just press the release button. The above is the working process and principle of the utility model. The utility model improves the efficiency of wire taking-up and wire releasing by arranging the first reel 12 and the second reel 13 to perform wire releasing or wire taking-up work synchronously, and through the double-reel design, the winding length of the wire inside the vacuum cleaner wire reel box 1 is increased, and the overall extendable length of the wire is increased, thereby expanding the working radius of the vacuum cleaner and enhancing the practical performance.
