The handle assembly (2) is foldable relative to the body assembly (1). One end in the width direction of the handle assembly (2) is hinged to the body assembly (1), and the other end in the width direction of the handle assembly (2) is detachably connected to the body assembly (1) through a locking mechanism (3).

[0004] Chinese Patent (CN202121840562.9) discloses a folding handle for a handheld vacuum cleaner, including a folding handle body. The bottom of the folding handle body is fixedly connected to the top of the vacuum cleaner body. The folding handle body includes a lightweight rod, and storage grooves are provided on both sides inside the lightweight rod, and folding rods are arranged inside the storage grooves.

[0005] Chinese Patent (CN202121968947.3) discloses a folding structure of a combined vacuum cleaner, which relates to the technical field of vacuum cleaners. It includes a vacuum cleaner handle installed at the top of the vacuum cleaner body. A flipping structure for folding the vacuum cleaner handle is installed between the vacuum cleaner handle and the vacuum cleaner body, and a buckle structure for connecting the vacuum cleaner body is installed in the lower part of the inner cavity of the vacuum cleaner handle.

[0006] Currently, for combined vacuum cleaners, the body of the vacuum cleaner can only be folded at the handle, which limits the storage space when the vacuum cleaner body is not in use. Moreover, combined vacuum cleaners usually use a dedicated handheld vacuum cleaner in combination with a dedicated vacuum cleaner body, resulting in poor versatility of the vacuum cleaner body. Summary of the Invention

[0007] The purpose of the present invention is to provide a foldable vacuum cleaner to solve the problems that combined vacuum cleaners usually use a dedicated handheld vacuum cleaner in combination with a dedicated vacuum cleaner body, and the body of the vacuum cleaner can only be folded at the handle, resulting in inconvenient storage of the vacuum cleaner body and the inability of the vacuum cleaner body to be suitable for assembly with different handheld vacuum cleaners.

[0008] To achieve the above object, the present invention adopts the following technical solution: A foldable vacuum cleaner, which includes a floor brush, a first bracket, a second bracket, a handle and a handheld vacuum cleaner. The first bracket is connected to the floor brush, the second bracket is hinged to the first bracket, the handle is hinged to the second bracket, the handheld vacuum cleaner is snap-connected to the floor brush, and the handheld vacuum cleaner is communicated with the floor brush. A fixing and adjusting mechanism is provided on the second bracket, and the fixing and adjusting mechanism clamps the handheld vacuum cleaner.

[0009] As a further description of the above technical solution:

[0010] A connecting pipe is provided on the floor brush, and the handheld vacuum cleaner is snap-connected to the connecting pipe.

[0011] As a further description of the above technical solution:

[0012] An expansion airbag is provided on the inner wall of the connecting pipe, and the expansion airbag wraps the handheld vacuum cleaner.

[0013] As a further description of the above technical solution:

[0014] Both the first bracket and the second bracket are arc-shaped. The first bracket is in a U shape with an upward opening, and the upper end of the first bracket clamps the lower end of the second bracket.

[0015] As a further description of the above technical solution:

[0016] The first bracket and the second bracket are connected by two knobs.

[0017] As a further description of the above technical solution:

[0018] The fixing and adjusting mechanism includes a main frame and two adjusting rods. The main frame is fixedly connected to the second bracket, the two adjusting rods are inserted into the main frame, and the two adjusting rods clamp the handheld vacuum cleaner.

[0019] As a further description of the above technical solution:

[0020] The main frame is in a C shape and the opening faces the handheld vacuum cleaner. A plurality of fixing holes are provided on the main frame, and the two adjusting rods are inserted into the fixing holes.

[0021] As a further description of the above technical solution:

[0022] Limit plugs are snap-connected to the opposite ends of the adjusting rod, and the limit plugs abut against the main frame.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In the present invention, after removing the handheld vacuum cleaner and loosening the knob, the second bracket can be folded along the first bracket, and the handle can be folded along the second bracket, so that the vacuum cleaner body can be folded multiple times, thereby minimizing the space occupied by the vacuum cleaner body and facilitating the storage of the vacuum cleaner body.

[0025] 2. In the present invention, by inserting the handheld vacuum cleaner into the connecting pipe, the expansion airbag wraps the handheld vacuum cleaner, and by inserting two adjusting rods into different fixing holes on the main frame, the distance between the two adjusting rods can be fixed, enabling it to clamp handheld vacuum cleaners with different body specifications, realizing the assembly of handheld vacuum cleaners with different specifications onto the same vacuum cleaner body for use, greatly improving the versatility of the vacuum cleaner body.
