Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaners, and in particular to an extension device for vacuum cleaners that allows for handheld use and extended use. Background Technology

[0002] Currently, common devices for extending vacuum cleaners include the "Handheld Vacuum Cleaner" (Chinese Invention Patent Publication No. CN118303782A), which discloses a handheld unit attached to the vacuum cleaner head via a thin tube. This handheld unit can clean items at greater distances, such as shelves, curtains, or ceilings. However, this increases the distance between the handheld unit and the vacuum cleaner head. As a result, the vacuum motor of the handheld unit needs more power to suck up dirt from the vacuum cleaner head compared to a standalone handheld unit. Therefore, there is room for improvement in extending the cleaning distance while maintaining appropriate power. Utility Model Content

[0003] This utility model provides an extension device for a vacuum cleaner, which mainly fixes the handheld vacuum cleaner by means of a support and a clip on the extension seat, while the extension seat is closely connected to the vacuum brush, forming a handheld vacuum cleaner that can extend the vacuum distance and perform vacuuming.

[0004] In order to achieve the aforementioned objectives, the present invention provides an extension device for a vacuum cleaner, comprising: an extension base that can be engaged or disengaged from a handheld vacuum cleaner, the extension base being provided with a support, a sleeve, a buckle, and a cover;

[0005] The bearing is provided with a protective cover, and a bearing socket is provided below the protective cover. The bearing socket extends with an interface and a through opening. A slot is provided on one side of the protective cover, and a slide is provided below the slot. The slide has a slot and multiple screw holes.

[0006] The sleeve has a slidable sleeve post relative to the slot and slide. A sleeve cap and tube seat are provided above the sleeve post, and a slide groove is provided below the sleeve post. A buckle is formed in the slide groove. The tube seat is for inserting the extension rod, and the extension rod is provided with a handle.

[0007] The slot can accommodate a buckle, which has a locking edge and an inner hole. A spring is fitted into the inner hole, so that the buckle can elastically return to its original position.

[0008] A cover is provided opposite the slide rail, and an opening is provided on the cover opposite the slot. Multiple studs are provided opposite the screw holes. The cover is fixed to the slide rail by screws, while the studs pass through the slide rail to restrict the vertical sliding space of the bearing.

[0009] The interface connects to the vacuum head, allowing the handheld vacuum cleaner's suction nozzle to pass through the opening for cleaning, thus creating a short-distance vacuuming process.

[0010] The handheld vacuum cleaner is fixed in place by the support and clip on the extension base. At the same time, the extension base is closely connected to the vacuum brush, forming a handheld vacuum cleaner with both extended and short-distance vacuuming capabilities. The control button and switch are connected via a transmission connection. The control button can operate the handheld vacuum cleaner. The transmission connection method can be wireless, wired, or Bluetooth.

[0011] Preferably, the cap has an air hole, and the handheld vacuum cleaner has an exhaust port that exhausts air through the air hole.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention uses a support and a clip on an extension base to fix a handheld vacuum cleaner, while the extension base is closely connected to a floor brush, forming a handheld vacuum cleaner that can extend the reach of the vacuum cleaner while providing short-distance cleaning.

[0054] Please refer to the extension device of this vacuum cleaner. Figure 1 The extension base 10 of the handheld vacuum cleaner 70 can be engaged or disengaged. The extension base 10 is provided with a support 20, a sleeve 30, a buckle 40 and a cover 50. The support 20 is provided with a cover 21. A recess 22 is provided below the cover 21. The recess 22 extends with an interface 221 and a through-hole 222. A slot 23 is provided on one side of the cover 21. A slide 24 is provided below the slot 23. A slot 241 and multiple screw holes 242 are provided in the slide 24.

[0055] The sleeve 30 is provided with a slidable sleeve post 31 relative to the slot 23 and the slide 24. The sleeve post 31 is provided with a cap 32 and a tube seat 33 above it. The sleeve post 31 is provided with a slide groove 311 below it. A buckle 312 is formed in the slide groove 311. The tube seat 33 is for the extension rod 34 to be inserted to form an extended vacuum cleaner. The extension rod 34 is provided with a handle 341 and a control key 342.

[0056] A buckle 40 is provided on the card slot 241. The buckle 40 has a card edge 41 and an inner hole 42, and a spring 43 can be fitted into the inner hole 42.

[0057] A cover 50 is provided relative to the slide rail 24. An opening 51 is provided on the cover 50 relative to the slot 241, and multiple studs 52 are provided relative to the screw hole 242. The cover 50 is fixed to the slide rail 24 by screws 53. At the same time, the studs 52 passing through the slide groove 311 can limit the space for the bearing 20 to slide up and down.

[0058] Interface 221 connects to a vacuum head 60 to create a short-distance vacuuming effect. The vacuum head 60 comes in various forms, such as a floor brush, a vacuum roller, or a vacuum nozzle.

[0059] The handheld vacuum cleaner 70 has a grip 71, a switch 72 on the grip 71, a suction port 73 at the bottom of the grip 71, and an exhaust port 74 at the top.

[0060] Figure 2 The handheld vacuum cleaner 70 is placed in the extension base 10. The handheld vacuum cleaner 70 is fixed by the cap 32 and the socket 22. The suction port 73 sucks up the dirt from the vacuum head 60 through the opening 222. In order to facilitate the exhaust port 74 to exhaust, the cap 32 is provided with air holes 321. In order to facilitate the use of the extended handheld vacuum cleaner 70, the control key 342 and the switch 72 are connected by a transmission connection. The control key 342 can operate the handheld vacuum cleaner 70. The transmission connection method is wireless, wired or Bluetooth.

[0061] Please refer to Figure 3 , Figure 4 and Figure 5 The handheld vacuum cleaner 70 rests against the cover 21 of the support 20 and is placed on the socket 22. The sleeve post 31 of the clip 30 is pressed into the slot 23 and the slide 24, so that the buckle edge 312 of the buckle 40 is fastened by the buckle edge 41, and the cap 32 covers and fixes the handheld vacuum cleaner 70. Since the buckle 40 is equipped with a spring 43, it can be elastically restored after being squeezed.

[0062] To remove the handheld vacuum cleaner 70, press the buckle 40 to disengage the buckle edge 41 from the buckle edge 312, then pull the sleeve 30 to allow the sleeve post 31 to slide on the slot 23 and the slide 24, so that the cap 32 releases the handheld vacuum cleaner 70 and removes it. Because the stud 52 passes through the slide 311, the sleeve 30 will not be pulled out of the support 20 due to the pulling action.

[0063] The foregoing description is a preferred embodiment of the present invention. However, in accordance with the spirit of the present invention, the cleaner can be implemented in various ways or with modifications, and the cleaner may even be configured without a motor. Therefore, obvious substitutions and modifications that can be made by those skilled in the art are still included within the scope of the patent claimed by the present invention.
