Description

Technical Field

[0001] The utility model relates to the technical field of steam cleaning devices, in particular to a rotating brush head structure. Background Art

[0002] The heavy oil and stubborn dirt in the kitchen are difficult to handle with ordinary detergents. It is often necessary to use various brushes, cleaning balls, scrapers and other tools in turn, which is very troublesome to clean. For this reason, people have developed various steam brush products for stubborn stains, such as the floor brush for steam cleaning equipment disclosed in Chinese patent CN105395142A and the steam cleaning equipment having the same, a body, an inlet and a nozzle are formed on the body; and a baffle, the baffle is arranged in the body, the baffle divides the interior of the body into a first chamber and a second chamber, the inlet corresponds to the first chamber, the nozzle is formed on the inner wall of the second chamber, the liquid in the fluid entering the body from the inlet flows into the first chamber, and the gas flows into the second chamber and is discharged from the nozzle.

[0003] At present, the brush heads of steam brush products sold on the market cannot rotate or rotate at a small angle, which makes it very difficult to clean corner areas. For example, Chinese patent CN207277035U discloses a steam brush with a rotatable nozzle, which includes a handheld main body, a steam generating device is arranged inside the main body, and a nozzle is arranged at the upper end of the main body, and the nozzle is rotatably connected to the main body. The upper end of the main body is detachably connected to a nozzle connecting portion, and the nozzle is rotatably connected to the nozzle connecting portion, and the main body steam channel runs through the nozzle connecting portion. The connecting portion is tightly matched with the main body steam channel.

[0004] In the existing steam brush products with rotatable nozzles, the nozzle and the main body are on the same plane during normal use, and ironing can be performed in the up and down directions. When the angle needs to be adjusted, the nozzle is pulled out for a distance and then rotated. When it needs to be restored, the nozzle is rotated to the original position and then pushed in. This structural setting is not very convenient to operate. For cleaning of kitchen environments and sanitary dead corners, frequent rotation of the nozzle will also cause problems with the sealing of the product. Therefore, the existing technology needs to be improved and developed. Utility Model Content
