Abstract
The utility model relates to an unpowered constant-pressure ventilator, comprising an air cover, an air inlet pipe, an air outlet pipe and a rotary sleeve, wherein the left side of the air cover is provided with an air inlet cover and the right side of the air cover is provided with the air outlet cover; an air inlet channel in the air inlet cover and an air outlet channel in the air outlet cover are respectively led out of the middle part of the air cover and are communicated with the air inlet pipe and the air outlet pipe by the rotary sleeve; and the lower ends of the air inlet pipe and the air outlet pipe are respectively communicated with indoor space. The unpowered constant-pressure ventilator has the advantages of novel structure, no power, no noise, ventilation by means of natural wind and large ventilation, and is convenient to use.
Description
Technical field
The utility model relates to a kind of room ventilation equipment, particularly a kind of unpowered constant voltage ventilator.
Background technology
Room ventilation device of the prior art, its majority is single tuyere-type, adopts gravity-flow ventilation or utilizes the blower fan forced ventilation, its weak point is: gravity-flow ventilation, its scavenging efficiency is low; Then noise is big to adopt blower fan.
Summary of the invention
The purpose of this utility model is exactly the weak point in looking for for fear of background technology, and a kind of novel structure is provided, unpowered device drives, noiseless unpowered constant voltage ventilator.
For achieving the above object, the utility model adopts following technical approach: unpowered constant voltage ventilator, described unpowered constant voltage ventilator comprises fan housing, blast pipe, discharge pipe and revolving sleeve, described fan housing left side is provided with air intake cover, its right side is provided with outlet housing, the interior air intake passage of described air intake cover is drawn respectively at the fan housing middle part with the interior air-out passage of outlet housing and is communicated with blast pipe and discharge pipe by revolving sleeve, and blast pipe and discharge pipe lower end are communicated with the interior space respectively.
For a kind of optimization of the present utility model, the air inlet of described blast pipe is positioned at the bottom of the interior space, and the air outlet of discharge pipe is positioned at the top of the interior space.
For a kind of optimization of the present utility model, the tuyere diameter of air intake cover is less than the tuyere diameter of outlet housing, and is connected for transition between air intake cover and the outlet housing.
The utility model is compared with background technology, has novel structure, and is easy to use, and unpowered, noiselessness rely on natural wind ventilation air-exchange, and ventilation volume is big.
Description of drawings
Fig. 1 is the structural representation of unpowered constant voltage ventilator.
The specific embodiment
Embodiment 1: with reference to Fig. 1.Unpowered constant voltage ventilator, described unpowered constant voltage ventilator comprises fan housing 1, blast pipe 2, discharge pipe 4 and revolving sleeve 3, described fan housing 1 left side is provided with air intake cover 1a, its right side is provided with outlet housing 1b, the interior air intake passage of described air intake cover 1a is drawn respectively at fan housing 1 middle part with the interior air-out passage of outlet housing 1b and is communicated with blast pipe 2 and discharge pipe 4 by revolving sleeve 3, and blast pipe 2 and discharge pipe 4 lower ends are communicated with the interior space 5 respectively.The air inlet 2a of described blast pipe 2 is positioned at the bottom of the interior space 5, and the air outlet 4a of discharge pipe 4 is positioned at the top of the interior space 5.The tuyere diameter of air intake cover 1a is less than the tuyere diameter of outlet housing 1b, and is connected for transition between air intake cover 1a and the outlet housing 1b.
What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
