Description

Technical Field

[0001] This application relates to the field of vacuum cleaners, and more particularly to a multi-functional vacuum cleaner. Background Technology

[0002] Vacuum cleaners are among the most commonly used cleaning tools in daily life and work. Common vacuum cleaners come in two types: upright and handheld. Each has its own advantages and disadvantages, and is used in different locations and situations. Upright vacuum cleaners have a floor brush and a push rod, allowing them to be pushed across the floor and are relatively easy to move, making them suitable for cleaning large areas of flooring and carpets. Handheld vacuum cleaners, on the other hand, are generally handheld, lighter, and the suction head is connected to the main unit by a plastic flexible hose, making them more suitable for cleaning corners, under beds, and under sofas. However, there is currently no vacuum cleaner that combines the features of both upright and handheld models. Utility Model Content

[0003] In order to improve the problem of combining an upright vacuum cleaner with a handheld vacuum cleaner into one unit, this application provides a multi-functional vacuum cleaner.

[0004] The multi-functional vacuum cleaner provided in this application adopts the following technical solution:

[0005] include:

[0006] Floor brush components;

[0007] The main unit is rotatably mounted on the floor brush assembly via a connector. The main unit includes a handle, a tube body mounted on the connector, and a dust collection box mounted on the tube body. The tube body is provided with a first connecting tube that communicates with the inside of the dust collection box, and the handle is provided with a second connecting tube that is inserted into the tube body.

[0008] A connecting mechanism for connecting the dustbin to the floor brush assembly or handle;

[0009] The connecting mechanism includes a first flexible hose connected to a first connecting pipe at one end, a first connecting component disposed on the pipe body, and a second connecting component disposed on a second connecting pipe; the other end of the first flexible hose is connected to the floor brush assembly or the second connecting pipe respectively through the first connecting component or the second connecting component.

[0010] By adopting the above technical solution, the first flexible hose is connected to the floor brush assembly or the second connecting pipe respectively through the action of the first and second connecting components, thereby combining the upright vacuum cleaner and the handheld vacuum cleaner into one unit. When the second connecting pipe is connected to the pipe body and the first flexible hose is connected to the floor brush assembly through the first connecting component, it can be used as an upright vacuum cleaner for cleaning floors. When the first flexible hose is connected to the second connecting pipe through the second connecting component and the second connecting pipe is removed from the pipe body, it can be used as a handheld vacuum cleaner for cleaning ceilings, curtains, and other objects. This also reduces the weight of the handheld vacuum cleaner and avoids the inconvenience and effort of installing components such as the negative pressure motor on the handle. Therefore, a user does not need to purchase both an upright and a handheld vacuum cleaner, improving the versatility of the vacuum cleaner.

[0011] In one possible implementation, the first connectivity component includes:

[0035] The mounting shell is fixedly installed on the outer wall of the tube.

[0036] The pressure plate is movably housed within the mounting housing;

[0037] The rotating rods are symmetrically fixed at both ends of the pressure plate, and rotate within the mounting housing.

[0038] The spring is connected at one end to the inner wall of the mounting housing and at the other end to the pressure plate.

[0039] The fourth locking block is fixedly located on the end of the pressure plate furthest from the spring;

[0040] Both the second connecting pipe and the pipe body are provided with a fourth slot that mates with the fourth locking block.

This also reduces the weight of the handheld vacuum cleaner and avoids the inconvenience and effort of installing components such as the negative pressure motor on the handle. Therefore, a user does not need to purchase both an upright and a handheld vacuum cleaner, improving the vacuum cleaner's versatility. Attached Figure Description

[0060] The second connecting component includes a third locking member 25 and a fourth locking member 26; the third locking member 25 is disposed on the second connecting pipe 7 and is used to disassemble and install one end of the first hose 8 into the second connecting pipe 7; the fourth locking member 26 is disposed on the second connecting pipe 7 and is used to disassemble and install the second connecting pipe 7 into the pipe body 4. The structure of the third locking member 25 is the same as that of the first locking member 11. Specifically, the third locking member 25 includes a third sleeve 27, a third inner cylinder 28, and a second elastic buckle 29. The third sleeve 27 is fixedly mounted on the second connecting pipe 7. The third inner cylinder 28 is located inside the third sleeve 27, and the inner wall of the third inner cylinder 28 is provided with a third internal thread 30 for connecting to the first flexible hose 8. The second elastic buckle 29 is symmetrically arranged on the outer wall of the third inner cylinder 28, and one end is engaged with the third sleeve 27.

One end of the second connecting tube 7 is inserted into the tube body 4 and abuts against the baffle 39. A connecting ring 40 is fixedly mounted on the second connecting tube 7, with one end abutting against the end of the tube body 4. The baffle 39 and the connecting ring limit the movement of the second connecting tube 7.

[0062] The specific operation process is as follows:

[0063] When cleaning the floor, the first hose 8 is secured to the third connecting pipe 9 via the first locking member 11, enabling upright vacuum cleaning. When cleaning high places such as ceilings or curtains, the first hose 8 is first untied from the third connecting pipe 9, then secured to the second connecting pipe 7 via the third locking member 25. The other end of the second connecting pipe 7 is then untied from the pipe body 4, enabling handheld vacuum cleaning. This allows for cleaning ceilings and curtains, while reducing the weight of the handheld vacuum cleaner and avoiding the inconvenience and effort of mounting components such as the negative pressure motor on the handle 3. This eliminates the need for a single user to purchase both upright and handheld vacuum cleaners, improving the vacuum cleaner's versatility.
