Abstract
The utility model relates to a human body inducing scavenger fan, which is composed of a machine body, a wind-in plate, etc. The machine body, the wind-in plate, etc., are mutually fixed. The inside of the machine body is provided with a worm centrifugal blower, and the side surface is provided with a withdrawable wind cover; the inside of the cover is provided with a wind-pressure-typed wind door; a middle window of the wind-in plate is provided with an inductor which is fixed on the machine body. The scavenger fan adopts special infrared wavelengths produced by the human body as signals, and the signals are focused on a heat-releasing electric infrared sensor through a fresnel lens; after the signals are processed through an infrared special-purpose integrated circuit, thyristor controls a motor of the scavenger fan to work so that the purposes of automatic operation and automatic cease. Even if a person leaves, the person does not need to worry about electric energy waste caused by the fact that the person forgets to shut the machine.
Description
The utility model relates to ventilation equipment, particularly the room ventilation air regenerating device.
As the room ventilation air regenerating device, ventilation fan is favored by people well and quite with its small and exquisite, cheap for manufacturing cost, ventilation effect simple in structure, it is installed in the place that kitchen, toilet, parlor, computer floor etc. need ventilation, its structure is made of body and air intake plate two parts, each ventilation fan that opens and closes all needs manual operation, and is cumbersome.
The purpose of this utility model is to overcome the defective of prior art and provides a kind of human body sensing principle of utilizing to exempt from the human body induction type ventilation fan that manual operation can reach the Auto Power On running and shut down and stop.
The purpose of this utility model is achieved in that and comprises body fastened to each other and air intake plate, the body part can be vertically mounted in the ceiling, in the volute centrifugal fan is housed, the outlet housing that can extract out is equipped with in the side, the wind pressure type air door is housed in the cover, it is characterized in that described air intake plate middle part has window, window is provided with the inductor that is fixed on the body.
Advantage of the present utility model has been to provide a kind of Automatic Ventilator of exempting manually operated top grade, also needn't worry because of having forgotten the waste of energy that shutdown causes even human body leaves, for people's life brings great convenience.
The utility model has following accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A place enlarged drawing of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 2.
To be described in detail again by above-mentioned accompanying drawing embodiment below.
As Figure 1-3, the human body induction type ventilation fan comprises body fastened to each other (1) and air intake plate (2), the body part can be vertically mounted in the ceiling, in the volute centrifugal fan is housed, the outlet housing (3) that can extract out is equipped with in the side, the wind pressure type air door is housed in the cover, air intake plate is fixed on the front end face of body, the position, intermediate portion has window, window is provided with the inductor (6) that is fixed on the body, inductor has 2 pins (7), utilize the elasticity and positioning seat (4) eye-splice connection mutually of plastics, positioning seat (4) is fixed on the body (1), and setting holds out against spring (5) between inductor (6) 2 pins (7), still can locate at grade with air intake plate (2) after rotational angle adjusts to satisfy inductor.
This ventilation fan with peculiar infrared wavelength that human body was produced as signal, focus to pyroelectric infrared sensor through Fresnel Lenses, after infrared special IC processing, by SCR control ventilation fan machine operation, thereby the purpose that reaches automatic running and stop to be applicable to occasions such as hotel, parlor, kitchen, toilet.
Claims (2)
1. human body induction type ventilation fan, comprise body fastened to each other (1) and air intake plate (2), the body part can be vertically mounted in the ceiling, in the volute centrifugal fan is housed, the outlet housing (3) that can extract out is equipped with in the side, the wind pressure type air door is housed in the cover, it is characterized in that described air intake plate middle part has window, window is provided with the inductor (6) that is fixed on the body.
