Abstract

The utility model discloses a motor-free ventilator, which comprises an impeller (1) and a casing (2), wherein the casing (2) comprises a cover board (21), a sidewall (22) and a soleplate (23), a water inlet pipe (3) connected with an air outlet of a building is fixed on the soleplate (23), the sidewall (22) is fixed on the soleplate (23), and an air outlet pipe (4) is fixed on the sidewall (22); the cover board (21) is fixed on the sidewall (22), a rotating shaft (5) is sleeved on the cover board (21), at least three ribs (6) with the same angle are fixed on one end of the rotating shaft (5), the impeller (1) is fixed on the other end of the rotating shaft (5), and the impeller (1) is arranged in the casing (2). According to the motor-free ventilator, the impeller (1) of a fan is driven to rotate through wind energy, and can work without free pollution; meanwhile, the electric energy is saved.

Description

A kind of no motor ventilator

Technical field:

The utility model relates to the ventilator technical field, more specifically to a kind of no motor ventilator.

Background technique:

Existing ventilator all is through driven by motor, and the energy is very in short supply in the world, and wind energy is a renewable resources, is carrying out in a lot of places through utilizing wind energy to generate electricity, and is being used on the ventilator wind energy actually rare.

The model utility content:

The purpose of the utility model is exactly the deficiency to existing technology, and a kind of no motor ventilator is provided, and it drives the wheel rotation that drives blower fan through wind energy, carries out work, and it is pollution-free, and the while is saving power again.

The technological solution of the utility model is following:

A kind of no motor ventilator comprises impeller and casing, and said casing is made up of cover plate, sidewall and base plate, is fixed with air intake pipe on the said base plate and communicates with the exhaust outlet of building, and sidewall is fixed on the base plate, is fixed with air outlet tube on the sidewall; Cover plate is fixed on the sidewall, the rotating shaft sleeve on the cover board, rotating shaft one end be fixed with at least three be equal angular fin, the other end is fixed with impeller, impeller is in casing.

Said impeller is the drum-type impeller, and said fin is the blade of windmill type.

The beneficial effect of the utility model is:

It drives fin rotation through wind energy, thus drive in the rotating shaft wheel rotation, will carry out work, it is pollution-free, simultaneously saving power again.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

The schematic representation that Fig. 2 distributes for the fin in the rotating shaft 6.

Among the figure: 1, impeller; 2, casing; 21, cover plate; 22, sidewall; 23, base plate; 3, air intake pipe; 4, air outlet tube; 5, rotating shaft; 6, fin.

Embodiment:

Embodiment: see that Fig. 1 is to shown in Figure 2; A kind of no motor ventilator; Comprise impeller 1 and casing 2, said casing 2 is made up of cover plate 21, sidewall 22 and base plate 23, is fixed with air intake pipe 3 on the said base plate 23 and communicates with the exhaust outlet of building; Sidewall 22 is fixed on the base plate 23, is fixed with air outlet tube 4 on the sidewall 22; Cover plate 21 is fixed on the sidewall 22, rotating shaft 5 sleeves on cover plate 21, rotating shaft 5 one ends be fixed with at least three be equal angular fin 6, the other end is fixed with impeller 1, impeller 1 is in casing 2.

Said impeller 1 is the drum-type impeller, and said fin 6 is the blade of windmill type.

Working principle: fin 6 is moved in wind, and fin 6 rotates the impeller 1 that has driven rotating shaft 5 the other ends, and impeller 1 just rotates the wind that the exhaust outlet with building comes out and sucks, and holds and then goes out from air outlet tube 4.
