Description
Technical field
The utility model relates to a kind of ventilation auxiliary device, particularly relates to a kind of supercharging air port.
Background technique
Popular on the market ventilation fan can make indoor air and outdoor cross-ventilation, to improve people's living environment.But ventilation fan can not be regulated air quantity, and start back passage does not block, and privacy is bad, and is not suitable for being contained in the ventiduct system of central heating.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and can regulate air quantity, private good, can install and use the supercharging air port at the central heating exhaust outlet.
The purpose of this utility model is achieved by following technical proposals: comprise shell and be installed in its inner motor and be fixed on impeller on the machine shaft, power line, switch and plug, mounting bracket in the cylindrical shell of described shell, the nut of through hole is installed by the central authorities of support; Regulate the back side central vertical secured adjusted screw mandrel of blast cap, regulate screw mandrel and be connected with nut thread; Shell is provided with panel away from the end of motor, forms the air channel that annular size can be regulated between the outer rim of the inboard of panel and adjusting blast cap.
Described panel is the flaring loop configuration of being with flange, and its outward edge is the combination shape of circle, rectangle, polygonal or straight line and curve.Described support is cross structure or plank frame with holes.Described shell and panel are structure as a whole or divide body structure; The simplified axial section of described shell is uniform section, variable cross section or ladder-type cross section.Described switch is the single-way switch of control motor unidirectional operation or the two-way switch of control motor operation just commentaries on classics counter-rotating.All component beyond described motor, power line, switch and the plug adopt ABS, nonmetal or metallic material making.
Compared with prior art, the utlity model has following advantage: air quantity can be regulated, privacy is good, not only can substitute ventilating fan and use, but also can use in the central heating system.Be applicable at home, office building, auditoriums, hotels and other need the place of air exchange to use.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
With reference to accompanying drawing 1-2, the utility model comprises shell 6 and is installed in its inner motor 5 and is fixed on impeller 4 in motor 5 rotating shafts, mounting bracket 8 in power line, switch and the plug, the cylindrical shell of described shell 6, and the nut 7 of through hole is installed by the central authorities of support 8; Regulate the back side central vertical secured adjusted screw mandrel 3 of blast cap 1, regulate screw mandrel 3 and be threaded with nut 7; Shell 6 is provided with panel 2 away from the end of motor 5, forms the air channel 9 that annular size can be regulated between the outer rim of the inboard of panel 2 and adjusting blast cap 1.
Described panel 2 is the flaring loop configuration of being with flange, and its outward edge is the combination shape of circle, rectangle, polygonal or straight line and curve.
Described support 8 is cross structure or plank frame with holes.
Described shell 6 is structure as a whole with panel 2 or divides body structure; The axial section of the cylindrical shell of described shell 6 is uniform section, variable cross section or ladder-type cross section.
Described switch is the single-way switch of control motor 5 unidirectional operations or the two-way switch of control motor 5 operations just commentaries on classics counter-rotating.
All component beyond described motor 5, power line, switch and the plug can adopt metal or nonmetallic material to make.
With reference to Fig. 3, on furred ceiling 11, open the hole of suitable shell 6 tail dimension, shell 6 afterbodys are connected with ventilation duct 10 after passing this hole.Ventilation duct 10 can lead to outdoor or lead to the unit of central heating.Lead under the outdoor situation at ventilation duct 10, switch can be selected two-way switch, both can air intake, and also can air draft.Being connected with the unit of central heating at ventilation duct 10 is to use single-way switch to indoor air intake.
With reference to Fig. 4, on body of wall 12, to open a suitable wall hole 13 and lead to outdoorly, shell 6 afterbodys are installed in wherein, and switch can be selected single-way switch or two-way switch.
Owing to regulate the rotation of blast cap 1, can change the size in air channel 9, realized that like this tuyere air volume can control and regulate; Because the rotation of motor and impeller can improve wind speed, give the ventilation supercharging; Blocked the air port owing to regulate blast cap 1, so privacy is good.
According to technology or the actual needs that use, shell 6 can merogenesis, uniform section or variable cross section are made.
