Abstract
The utility model relates to a ventilator used in a passenger car, comprising a fan at the top and a ventilation duct positioned at the bottom of the fan; wherein, a start-stop closing cap is positioned on the inner aperture of the ventilation duct. Since a start-stop closing cap is positioned on the inner aperture of the ventilation duct, the closing cap is spirally fixed with the internal wall of the ventilation duct and the claws on the closing cap are sequentially corresponding to the slide rails meshed with the internal wall of the ventilation duct and arranged evenly, which enable the ventilation duct to be opened by turning the closing cap anticlockwise or clockwise for ventilation; the ventilation duct can be closed by turning the closing cap clockwise or anticlockwise when ventilation is not needed which ensures good sealing; moreover, the utility model has little noise and good ventilation effect. The end caps arranged at the two ends of the slide rails can prevent the closing cap from disengaging with the slide rails in rotation.
Description
Technical field
The utility model relates to a kind of passenger vehicle ventilation fan.
Background technique
Passenger car is under the air-tight state for a long time, and air can't circulate, and needs to ventilate, breathe freely, and keeps with fresh air.At present, main fan against the wind and the vehicle window by car that ventilate in the car carries out, and the window against the wind of car has possessed the function of ventilation, ventilation basically, but the collocation of itself and compartment inner top is inharmonious, thereby influenced the overall aesthetic of car inner top; In addition, when not needing to ventilate in the car, the sealing of window is poor against the wind, and noise is big, the ventilation volume deficiency, and dust in air easily reaches against the wind from vehicle window, and window makes the compartment very unhygienic into the car.
The model utility content
At the problems referred to above, the purpose of this utility model is to provide a kind of passenger vehicle ventilation fan, to increase sealing, reduces noise.
To achieve these goals, the technical solution of the utility model is to provide a kind of passenger vehicle ventilation fan, and this ventilation fan is made of the fan body at top and the ventilation road of fan body bottom assembling, on the internal orifice in ventilation road the capping that can open and close is installed.
Spiral is assembled together between described capping and the ventilation road inwall.
Evenly be provided with twice spirality projection slide rail at least on the inwall in ventilation road, correspondence is provided with at least two claws in the capping, and the corresponding successively slip of each claw is stung and is contained on each slide rail.
The two ends of each slide rail are provided with the plug that prevents the claw derailing.
Be equipped with the spring that is used to compress slide rail radially in each claw.
The bottom surface of capping is provided with the handle that is used to open and close.
The week of capping is inlaid in the ring seam in ventilation road when the edge is closed.
Owing on the internal orifice in the ventilation road of the fan body of this ventilation fan bottom assembling the capping that can open and close is installed, spiral is assembled together between capping and the ventilation road inwall, corresponding successively slip of claw in the capping stung on each slide rail that is contained in even setting on the ventilation road inwall, like this when needs are taken a breath, only need along counterclockwise or the clockwise direction rotary closure to open the ventilation road, be used for ventilated; When not needing to take a breath, can have good sealing, and can make ventilation fan and compartment inner top be integrated along the clockwise or road of the next closed ventilation of rotary closure counterclockwise; And noise is little, and ventilation effect is good.The plug that the two ends of each slide rail are provided with can prevent that capping breaks away from slide rail when rotated.Ventilation fan of the present utility model and compartment inner top one integrated mass increased the overall aesthetic of car body inner top, and sealing effect are fabulous, easily applies.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1;
Fig. 3 is the unfolded drawing of the ventilation road inwall among Fig. 1.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, passenger vehicle ventilation fan of the present utility model is made of the fan body 7 at top and the ventilation road 2 of fan body 7 bottoms assembling, on the internal orifice in ventilation road 2 capping 1 that can open and close is installed, spiral is assembled together between capping 1 and ventilation road 2 inwalls, evenly be provided with three road spirality projection slide rails 3 on the inwall in ventilation road 2, correspondence is provided with three claws 5 in the capping 1, the corresponding successively slip of each claw 5 is stung and is contained on each slide rail 3, the two ends of each slide rail 3 are provided with the plug 9 that prevents claw 5 derailings, be equipped with the spring 4 that is used to compress slide rail 3 radially in each claw 5, the bottom surface of capping 1 is provided with the handle 6 that is used to open and close.The week of capping 1 is inlaid in the ring seam in ventilation road 2 when the edge is closed.When needs were taken a breath, only needing in the counterclockwise direction, rotary closure 1 was used for ventilated to open ventilation road 2; When not needing to take a breath, can be rotated in a clockwise direction capping 1 closed ventilation road, when guaranteeing good sealing property, make ventilation fan and compartment inside ceiling panel 8 keep integrated, increase the overall aesthetic of compartment inner top.
