AIRFLOW CONTROL FOR AN INTEGRATED HANDHELD TEXTURE SPRAYER |
| 摘要 |
A handheld sprayer includes a housing, a turbine, a spray tip, and a hopper. An air flow passage extends through the housing. The turbine is configured to generate an airflow within the air flow passage. The spray tip is positioned to receive airflow from the air flow passage. The hopper is connected to the housing and configured to discharge a fluid into the air flow passage. In one embodiment a valve is positioned within the air flow passage and configured to control the airflow from the turbine to the spray tip. In another embodiment, a voltage limiting circuit is configured to control voltage to an electric motor of the turbine to control speed of the turbine. In another embodiment, an air inlet control device is configured to control the air intake of the turbine. |
