Abstract
The utility model discloses a wind force automatic ventilating fan. The wind force automatic ventilating fan is provided with a rotating shaft (1), a fan slice (2) is connected with the rotating shaft (1), and the upper end and the lower end of the rotating shaft (1) are connected with a fixing bracket (4) by a bearing (3). The utility model is mounted on the top end of a ventilating duct of a building, the fan slice of the utility model can rotate under the action of wind force, and then, negative pressure is generated inside the ventilating duct, which can draw out the discharge gas in a kitchen or a toilet to obtain the purpose of ventilating. A householder does not need to self-mount a fume exhaust ventilator and an exhaust fan, and the expense of the householder is saved. The utility model need not consume electric energy, which can relieve the increasingly nervous status of the electric energy. The phenomenon of 'clustering of tastes' among householders can be efficiently avoided, and the utility model is provided with higher economical benefit and social benefit.
Description
Technical field:
The utility model relates to a kind of ventilation fan, especially can be applicable to the wind-force Automatic Ventilator on top, constructure ventilation road.
Background technique:
At present, substantially all be provided with the uncovered ventilation flue in its upper end in the building, resident family can communicate the ventilating fan outlet of the lampblack exhauster in kitchen or toilet with ventilation flue, by the machine operation of lampblack exhauster or ventilating fan, with waste gas discharges such as flue gas that kitchen or toilet produced, foul smell.This kind exhaust mode exists following shortcoming:
1. resident family must install lampblack exhauster and ventilating fan voluntarily, not only brings bigger trouble to resident family, and has increased the spending of resident family;
2. must be under the condition of lampblack exhauster or electrical machinery of ventilator work could exhaust, need expend a large amount of electric energy;
3. when in the big or ventilation flue top-down downdraught being arranged when air displacement, the phenomenon of " taint of odour " between each resident family appears easily.
Summary of the invention:
The utility model is in order to solve existing in prior technology consume electric power and easy technical problems such as " taints of odour ", a kind of wind-force Automatic Ventilator that need not consume electric power, can avoid " taint of odour " to be provided.
Technical solution of the present utility model is: a kind of wind-force Automatic Ventilator, be provided with rotating shaft 1, and be connected to fan sheet 2 with rotating shaft 1, the two ends up and down of rotating shaft 1 join by bearing 3 and fixing frame 4.
The two ends up and down of described fan sheet 2 join with last fixed tray 5, lower fixed disk 6 respectively, and last fixed tray 5, lower fixed disk 6 join with rotating shaft 1.
The longitudinal cross-section of described fan sheet 2 is circular-arc.
Described fixing frame 4 is a frame structure.
The utility model is installed on the top in constructure ventilation road, and its fan sheet can rotate under the effect of wind-force, produces negative pressure then in ventilation flue, the waste gas of kitchen or toilet can be extracted out, reach the purpose of ventilation.Need not resident family lampblack exhauster and ventilating fan are installed voluntarily, saved the spending of resident family; Need not consume electric power, can alleviate the growing tension situation of electric energy; Can effectively avoid " taint of odour " phenomenon between the resident family, have high economic benefit and social benefit.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the utility model embodiment's a scheme of installation.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: be provided with rotating shaft 1, be connected to fan sheet 2 with rotating shaft 1, the two ends up and down of rotating shaft 1 join by bearing 3 and fixing frame 4.Fan sheet 2 can be directly joins with rotating shaft 1, also the two ends up and down of fanning sheet 2 can be joined with last fixed tray 5, lower fixed disk 6 respectively, joins by last fixed tray 5, lower fixed disk 6 and rotating shaft 1.Its fan sheet 2 preferably longitudinal cross-section is circular-arc, and fixing frame 4 also is preferably frame structure, can maximally utilise wind-force.
Install as shown in Figure 2: the lower end of fixing frame 4 is fixed on the air exhaust channel 8 by bolt 7, the utility model is suspended from the air exhaust channel 8, wind-force can make fan sheet 2 rotate in the upper end of air exhaust channel 8, then in ventilation flue, produce negative pressure, the waste gas of kitchen or toilet can be extracted out, reach the purpose of ventilation.
