Description
Technical Field
[0001] This utility model belongs to the field of vacuum cleaner technology, specifically relating to a vacuum cleaner. Background Technology
[0002] A vacuum cleaner is a device that uses air pressure differences to draw dust and other contaminants into its interior.
[0003] Vacuum cleaners can include the vacuum cleaner body and the nozzle assembly. Replacing the existing nozzle assembly requires replacing the entire vacuum cleaner. Vacuum cleaners are sold with multiple different nozzle assemblies, which results in a large space occupation during transportation. If only one nozzle assembly is purchased, the function is limited to vacuuming and does not have a mopping function. Therefore, it is very important to obtain a vacuum cleaner that overcomes the above defects. Utility Model Content

[0005] The vacuum cleaner body is used to generate vacuum suction.
[0006] The nozzle assembly is connected to the vacuum cleaner body via a connecting tube;
[0007] The suction head assembly includes a first connector, a third connector, and a second connector connecting the first connector and the third connector; the first connector is connected to the body of the vacuum cleaner via a connecting tube; the third connector has a suction port at its bottom.
[0008] The first connector has a first part of a spherical rotating groove, the third connector has a third part of a spherical rotating groove, the second connector includes a first sphere that mates with the first part of the spherical rotating groove, a third sphere that mates with the third part of the spherical rotating groove, and a connecting post that connects the first sphere and the three spheres, and the second connector has a communicating channel.
[0009] The inner walls of the third connectors located on both sides of the inlet are each fixed with a rotating column, and also include a roller.

The surface of the roller has a spiral groove, and the surface of the roller outside the spiral groove has an installation hole. A silicone diaphragm is fixed to the inner wall of the installation hole, and the silicone diaphragm has a cross-shaped perforation. A disposable cotton towel is also included, with at least a portion of the cotton towel inserted into the cross-shaped perforation of the installation hole.
[0010] Through the above technical solution, the disposable cotton towel of this utility model can be reused after being used on the face. The cotton towel is inserted into the cross-shaped perforation of the installation hole, which is convenient for disassembly and assembly and makes reasonable use of resources. It can be used for roller mopping, and due to the vacuum suction of the vacuum cleaner body, hair can be adsorbed on the roller.
[0011] The roller includes a first cylinder and a second cylinder. The first end of the first cylinder is contracted to form an insert for insertion into the second cylinder. A guide groove is provided on the outer wall of the second cylinder. A limiting block located in the guide groove is fixed on the outer wall of the insert. A limiting post is integrally formed inside the second cylinder. A spring is fixed between the limiting post and the end of the insert.
[0012] Through the above technical solution, the first and second cylinders of this utility model can be retracted during disassembly and installation, and the spring setting can stably press the first and second cylinders against the rotating column.
[0013] The first part of the spherical rotating groove is interference-fitted with the first sphere to generate damping, and the third part of the spherical rotating groove is interference-fitted with the third sphere to generate damping.
[0014] Through the above technical solution, the interference fit can increase friction and generate damping, thereby achieving rotational limit.
[0015] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, which is conducive to the disassembly and installation of the roller. A handle can be fixedly installed on the first connecting member for hand holding. The connecting tube is sealed and connected in the existing way, which can realize multi-angle rotation. In addition, the installation method of disposable cotton soft towel is convenient and facilitates the secondary use of resources. Attached Figure Description
