Abstract
The utility model provides a turbine ventilator, relates to the field of indoor air ventilation and is applied to roof natural ventilation. The turbine ventilator comprises arc-shaped fan blades, a head cover, a center shaft, a center shaft support, a bottom coil and a bottom neck strap. The arc-shaped fan blades are connected between the bottom coil and the head cover to form a turbine. The center shaft is connected to the head cover. The center shaft support is arranged on the bottom neck strap and connected with the center shaft. The bottom neck strap is sleeved with the bottom coil. The turbine ventilator has the advantages that rain water does not drip into a room along the arc-shaped fan blades due to the fact that the bottom neck strap is sleeved with the bottom coil.
Description
Technical field
The utility model relates to the room ventilation field, is applied to roof natural-ventilation.
Background technique
Current turbine-driven fan is because central shaft runs up for a long time, and the turbine maple leaf is yielding, affects the working life of ventilator, and bottom coil only plays the effect that connects arc fan blade bottom, and when wind and rain is arranged, rainwater can drip to along the arc fan blade indoor.
Summary of the invention
The purpose of this utility model is: provide a kind of water-tight, the turbine-driven fan of long service life.
In order to achieve the above object, taked technological scheme is:
A kind of turbine-driven fan, comprise the arc fan blade, top cover, central shaft, middle pedestal, bottom coil, end neck ring is characterized in that: described arc fan blade is connected between bottom coil and top cover, form turbine, central shaft is connected on top cover, and axis is set up on end neck ring and with central shaft and is connected, and described bottom coil is enclosed within outside end neck ring.
The effect that the utility model reaches is: because bottom coil is enclosed within outside end neck ring, rainwater can not splash into along the arc fan blade indoor.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1. arc fan blade, 2. top cover, 3. central shaft, 4. in pedestal, 5. bottom coil, 6. end neck ring.
Embodiment
From accompanying drawing 1, the utility model comprises arc fan blade 1, top cover 2, central shaft 3, middle pedestal 4, bottom coil 5, end neck ring 6.Described arc fan blade 1 is connected between bottom coil 5 and top cover 2, forms turbine, and central shaft 3 is connected on top cover 2, and middle pedestal 4 is located on end neck ring 5 and with central shaft 3 and is connected, and described bottom coil 5 is enclosed within outside end neck ring 6.
During use, the utility model utilizes natural wind, and the poor air thermoconvection caused of indoor and outdoor temperature, thereby promote the turbine rotation, utilizes centrifugal force and underbalance effect that indoor stale hot air is discharged.
The connection function of central shaft 3, make never to be out of shape at the fan blade of the lower turbine that runs up, thus the working life of having improved greatly ventilator.Because bottom coil 5 is enclosed within outside end neck ring 6, rainwater can not splash into indoor along arc fan blade 1.
It should be noted that above embodiment can not be considered to for limiting practical range of the present utility model, all equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
