Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, in particular to a handheld vacuum cleaner. Background Art

[0002] With the popularization of technology and for the convenience of use, existing vacuum cleaners can be operated and used by hand. Existing handheld vacuum cleaners generally include a handpiece, a dust hood and an air guide hood. The handpiece is provided with a dust suction component that provides dust suction power and an air blowing component that provides air blowing power. The dust hood is generally connected to the handpiece, and the dust hood can cover the air suction hood located at the front end of the handpiece. The air guide hood is connected to the rear end of the handpiece, and the air guide hood can also cover the air outlet hood located at the rear end of the handpiece. The dust hood and the air guide hood can be removed from the handpiece and reassembled.

[0003] However, the above-mentioned handheld vacuum cleaner has a defect: when the disassembled dust hood and air guide hood are assembled with the handpiece again, the dust hood and the handpiece, as well as the air guide hood and the handpiece, cannot be quickly positioned and matched, and even need to be corrected through multiple running-in to achieve accurate matching of the dust hood and the handpiece, as well as the air guide hood and the handpiece. This defect makes the handheld vacuum cleaner inconvenient to use to a certain extent. Summary of the invention

[0004] The utility model aims to provide a handheld vacuum cleaner which can quickly position and match a dust cover, an air guide cover and a machine head.

[0005] To achieve the above objectives, the technical solution adopted by the utility model is: a handheld vacuum cleaner, comprising a handpiece, a dust hood and an air guide hood, the dust hood and the air guide hood being respectively connected to the front and rear ends of the handpiece, a magnetic structure being provided between the dust hood and the handpiece, and between the air guide hood and the handpiece, the dust hood and the handpiece being connected together by the magnetic structure located therebetween, and the air guide hood and the handpiece being connected together by the magnetic structure located therebetween.

[0006] Compared with the prior art, the advantages of the utility model are: the magnetic structure can realize the rapid positioning between the dust hood, the air guide hood and the machine head without multiple attempts or adjustments, which significantly improves the assembly efficiency. Traditional mechanical buckles may require precise alignment to install, while the magnetic structure can automatically attract the alignment, which greatly simplifies the assembly process and enables users to perform disassembly and assembly operations more easily. The magnetic design not only makes assembly more convenient, but also provides a smooth use experience and enhances the user-friendliness of the product. Compared with traditional mechanical buckles, the magnetic structure reduces the wear caused by repeated disassembly and assembly, and extends the service life of the product. Improved safety: The magnetic structure ensures a stable connection between the components and avoids safety hazards caused by looseness during use. Magnetic connections are usually quieter than mechanical buckles, which helps reduce the noise level when the equipment is running and improves the comfort of the use environment.
