Abstract: PURPOSE:To extinguish ticks by means of a high temperature by coupling a main body to have a built-in fan motor and a floor nozzle to have a built-in rotary brush so as to be relatively turnable, providing air outlets in distributing them up and down in the lower part of the main body, and providing a closing cover to close either of the air outlets at the time of turning the floor nozzle. CONSTITUTION:In order to fit a floor nozzle onto a surface to be cleaned, it is turned to a main body 10 so that the front can be made lower. Then, since a closing cover 31 is simultaneously turned downward, a downward air outlet 27 is closed by the closing cover 31, and consequently, a purified air is exhausted from an upward air outlet 16. When the floor nozzle 13 is turned, a fixed groove 29 is coupled to a click part 28 and the floor nozzle 13 is supported by the main body 10, since the closing cover 31 is simultaneously turned upward, the upward air outlet 16 is closed, and the purified air is exhausted from the downward air outlet 27. At such a time, since the exhaust area of the downward air outlet 27 is made smaller than that of the upward air outlet 16, a temperature inside the main body 10 is raised, and also for the purified air exhausted from the downward air outlet 27, the temperature is raised. Consequently, the ticks to reproduce themselves on the surface to be cleaned can be extinguished by the air at a high temperature exhausted from the downward air outlet 27.
