Description

Technical Field

[0001] This utility model relates to the field of canister vacuum cleaners, and more particularly to a cord winding mechanism and a vacuum cleaner. Background Technology

[0002] Canister vacuum cleaners are a common type of vacuum cleaner. The current structure of canister vacuum cleaners is shown in patent publication document CN208573574U. There is a problem with this structure: the power cord is secured by an L-shaped buckle on the outer wall. Therefore, when rewinding the cord, it is wrapped and buckled on the outer wall of the canister vacuum cleaner, which makes the cord susceptible to damage from external objects. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a cable winding mechanism. By rotating a winch, the winch can wind and store or release the power cord. When the power cord is wound and stored, it is placed between the winch and the outer cover, thus achieving protective storage of the power cord.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A winding mechanism includes a top cover and an outer cover, the outer cover being fixedly mounted on the top cover. It also includes a winch and a power cord. The winch is rotatably mounted inside the outer cover. The top cover has a first conductive ring and a second conductive ring. One end of the power cord is fixed to the winch. The winch has a first conductive contact and a second conductive contact. The first conductive contact slides in engagement with the first conductive ring, and the second conductive contact slides in engagement with the second conductive ring. The first conductive ring and the second conductive ring do not contact each other. The neutral wire and the live wire on the power cord are respectively connected to the first conductive contact and the second conductive contact.

[0006] In this type of winding mechanism, the first conductive ring and the first conductive contact are in a sliding contact state, and the second conductive ring and the second conductive contact are in a sliding contact state. This achieves that the first conductive ring and the second conductive ring are indirectly connected to the neutral wire and the live wire of the power supply, respectively.

[0007] In this type of winding mechanism, one end of the power cord is fixed to the winch. Therefore, when the winch rotates in different directions, the power cord can be wound and stored or released on the winch. Simultaneously, during the winding and storage process, when the winch winds and stores the power cord, it is wound and stored between the winch and the outer casing, thus achieving protective storage of the power cord. The conductive contacts and conductive rings will not lose contact, ensuring that the circuit remains conductive at all times.

[0008] In summary, in this type of cable winding mechanism, the winch is rotated to wind and store or release the power cord. When the power cord is wound and stored, it is stored between the winch and the outer cover, which can achieve protective storage of the power cord.

[0009] The specific outer cover is located on the top cover.

[0010] Optionally, a handle cover is also included, which is fixedly fitted to the top cover by connecting bolts.

[0011] The handle cover is for easy carrying.

[0012] Optionally, the winch has an annular groove, and the handle cover is rotatably engaged with the winch, with the handle cover located within the annular groove.

[0013] The handle cover is located inside the annular groove of the winch, and the winch can rotate relative to the handle cover to ensure high stability when the winch rotates.

[0014] Optionally, it also includes a spring, which is sleeved on the handle cover, with one end of the spring abutting against the winch and the other end of the spring abutting against the handle cover.

[0015] A spring is fitted onto the handle cover, with one end of the spring abutting against the winch and the other end abutting against the handle cover. Since the handle cover is essentially a top cover and is in a fixed installation state, while the winch is in a state where it can rotate and float up and down relative to the top cover, a spring is further provided. The two ends of the spring abut against the winch and the handle cover respectively. The spring force propels the winch toward one side of the first conductive ring and the second conductive ring, so that the first conductive contact is pressed against the first conductive ring and the second conductive contact is pressed against the second conductive ring.

[0016] Optionally, the handle cover includes a connecting post and a cover plate, the cover plate being disposed at one end of the connecting post, the connecting post being T-shaped, and the connecting bolt being engaged with the connecting post.

[0017] The cover is also equipped with a handle, which is located on both sides of the cover, allowing you to grip and lift the entire handle cover.

[0018] Optionally, the winch is provided with a handle.

[0019] The purpose of the handle is to facilitate cranking the winch.

[0020] Optionally, the outer cover is a cylindrical outer cover, and one end of the outer cover is provided with a stepped ring, and one end of the winch is close to the stepped ring.

[0021] One end of the winch is pressed tightly against the stepped ring of the outer cover. This is to ensure the integrity of the seal between the winch and the outer cover and to prevent dust from seeping in between the winch and the outer cover.

[0022] A vacuum cleaner includes a cord retraction mechanism as described above.

[0023] The beneficial effects of this utility model are: by rotating the winch, the winch can wind and store or release the power cord through its own rotation. When the power cord is wound and stored, it is stored between the winch and the outer cover, which can achieve protective storage of the power cord. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] Example 1

[0033] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, a winding mechanism includes a top cover 7 and an outer cover 1. The outer cover 1 is fixedly mounted on the top cover 7. The mechanism also includes a winch 2 and a power cord 4. The winch 2 is rotatably mounted inside the outer cover 1. The top cover 7 is provided with a first conductive ring 801 and a second conductive ring 802. One end of the power cord 4 is fixed to the winch 2. The winch 2 is provided with a first conductive contact 901 and a second conductive contact 902. The first conductive contact 901 is slidably engaged with the first conductive ring 801, and the second conductive contact 902 is slidably engaged with the second conductive ring 802. The first conductive ring 801 and the second conductive ring 802 do not contact each other. The neutral wire and the live wire on the power cord 4 are respectively connected to the first conductive contact 901 and the second conductive contact 902.

[0034] In this type of winding mechanism, the first conductive ring 801 and the first conductive contact 901 are in sliding contact, and the second conductive ring 802 and the second conductive contact 902 are in sliding contact. This achieves that the first conductive ring 801 and the second conductive ring 802 are indirectly connected to the neutral wire and the live wire of the power line 4, respectively.

[0035] In this type of winding mechanism, one end of the power cord 4 is fixed to the winch 2. Therefore, when the winch 2 rotates in different directions, the power cord 4 can be wound and stored or released on the winch 2. At the same time, during the winding and storage or release process, when the winch 2 winds and stores the power cord 4, the power cord 4 is wound and stored between the winch 2 and the outer cover 1, thereby achieving protective storage of the power cord 4. The conductive contact piece and the conductive ring will not lose contact, ensuring that the circuit is always in a conductive state.

[0036] In summary, in this type of winding mechanism, the winch 2 is rotated, and the winch 2 can wind and store or release the power cord 4 through its own rotation. When the power cord 4 is wound and stored, the power cord 4 is stored between the winch 2 and the outer cover 1, which can achieve protective storage of the power cord 4.

[0037] The outer cover 1 is specifically installed on the top cover 7.

[0038] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, it also includes a handle cover 302, which is fixedly fitted together with the top cover 7 by connecting bolts 6.

[0039] The handle cover 302 is there to facilitate carrying by hand.

[0040] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the winch 2 has an annular groove, and the handle cover 302 is rotatably engaged with the winch 2, with the handle cover 302 located inside the annular groove.

[0041] The handle cover 302 is located in the annular groove of the winch 2. The winch 2 can rotate relative to the handle cover 302 to ensure that the winch 2 has high stability when rotating.

[0042] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, it also includes a spring 5, which is sleeved on the handle cover 302. One end of the spring 5 abuts against the winch 2, and the other end of the spring 5 abuts against the handle cover 302.

[0043] Spring 5 is sleeved on handle cover 302. One end of spring 5 abuts against winch 2, and the other end of spring 5 abuts against handle cover 302. Since handle cover 302 is equivalent to top cover 7 and is in a fixed installation state, winch 2 is in a state that can rotate and float up and down relative to top cover 7. Therefore, spring 5 is further provided. The two ends of spring 5 abut against winch 2 and handle cover 302 respectively. The elastic force of spring 5 will push winch 2 towards one side of first conductive ring 801 and second conductive ring 802, so that first conductive contact 901 is close to first conductive ring 801 and second conductive contact 902 is close to second conductive ring 802.

[0044] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the handle cover 302 includes a connecting post 303 and a cover plate. The cover plate is disposed at one end of the connecting post 303. The connecting post 303 is T-shaped, and the connecting bolt 6 is engaged with the connecting post 303.

[0045] The cover is also equipped with a handle, which is located on both sides of the cover and the connecting post 303. The entire handle cover 302 can be picked up by gripping it.

[0046] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, a handle 201 is provided on the winch 2.

[0047] The purpose of setting handle 201 is to facilitate the cranking of winch 2.

[0048] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the outer cover 1 is a cylindrical outer cover 1, and one end of the outer cover 1 is provided with a stepped ring 101, and one end of the winch 2 is attached to the stepped ring 101.

[0049] One end of the winch 2 is pressed tightly against the stepped ring 101 of the outer cover 1. This is to ensure the integrity of the seal between the winch 2 and the outer cover 1 and to prevent dust from seeping in between the winch 2 and the outer cover 1.

It should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
