Description

Technical Field

[0001] The utility model relates to the field of aerosol nozzles, and particularly relates to an angle-adjustable dual-purpose nozzle. Background Art

[0002] The angle-adjustable dual-purpose nozzle is widely used. As Figure 1 shown, its basic principle is to set two independent flow channels on the rotatable nozzle 1, the axes of the two flow channels are perpendicular to each other. When the nozzle 1 is horizontal, one of the flow channels is connected to the upstream flow channel and can spray materials. After the nozzle 1 rotates downward by 90°, the other flow channel is connected to the upstream flow channel and can spray materials. The spray shapes of the two flow channels are different. Usually, an extension tube 2 is also provided on one of the flow channels to meet diverse spray requirements. However, it is found in the actual development and application process that when the nozzle 1 rotates downward by 90°, the extension tube 2 will be close to the aerosol bottle body 3. At this time, when the button is pressed to spray the flow channel, the extension tube 2 will interfere with the aerosol bottle body 3, affecting the downward pressing of the button and the smooth spraying of materials, and there is a certain room for improvement.
