- The present disclosure relates to a cleaner and a method of manufacturing a brush drum of the cleaner capable of performing cleaning without lifting a brush head even when large foreign substances exist on a surface to be cleaned.
- In general, a cleaner is an apparatus that sweeps or scatters foreign substances such as dust or hair existing in the cleaning space, and suctions foreign substances such as scattered dust or hair by suction power to clean an area to be cleaned.
- The cleaner includes a body, a brush head connected to the main body by a connection pipe and having a suction port, and a brush drum rotatably mounted to the brush head.
- The brush drum includes a drum base formed of rigid metal or plastic, and a brush formed of soft fibrous hair having a predetermined length on the outer circumferential surface of the drum base.
- In response to the scattering of the foreign substances such as dust and hair existing in the cleaning space by the rotation of the brush drum, the foreign substances such as scattered dust and hair are sucked into the suction port by the suction force generated inside the main body, and the sucked foreign substances are moved to a dust container.
- In response to the amount of foreign substances present in the cleaning space being large, the foreign substances may come into contact with the drum base during the cleaning process, causing the front portion of the brush head to be momentarily lifted and the internal vacuum level to decrease, and the foreign substances to be pushed forward without being sucked.
- In addition, the brush head is lifted and large foreign substances enter the suction port inside the brush head at once, which may cause the suction port to become blocked.
- Therefore, it is an aspect of the disclosure to provide a cleaner and a method of manufacturing a brush drum of the cleaner, which may perform cleaning while maintaining a state in which the brush head is in close contact with a surface to be cleaned by including an elastic member in which the brush drum is elastically deformed.
