Institute.
Ventilation blower is typically mounted at roof, and ventilating opening is arranged on mounting surface side.Existing ventilator not to ventilating opening at
Valve do encapsulation process, the noise outside room easily enters in room from ventilating opening, influences indoor environment, is unfavorable for indoor residence
The firmly physical and mental health of personnel.
Utility model content
To provide a kind of noiseproof ceiling type ventilation of room device, the ventilator has good the purpose of this utility model
Soundproof effect, it can prevent outside noise from entering by ventilator in room.
To achieve these goals, ceiling type ventilation of room device provided by the utility model includes casing, installed in casing
Interior impeller and motor and the air intake air diffuser on casing one side of driving wheel rotation, the mounting surface of casing
Side is provided with ventilating opening；The cross section of ventilating opening is circle, and a transverse axis is provided with along its diametric(al), on the transverse axis activity install
There is a circular valve coordinated with ventilating opening；Valve is opening up a fluting at transverse axis both ends, and the edge of valve is divided into
Two halves, half are inwardly turned into the first sound insulation groove, and second half flips over into the second sound insulation groove；The inwall of ventilating opening, which is provided with, works as
The the first sound insulation ring coordinated when valve closes with the first sound insulation groove, and the second sound insulation ring coordinated with the second sound insulation groove；First
Acoustical cotton is filled between the binding face and the binding face of the second sound insulation groove and the second sound insulation ring of sound insulation groove and the first sound insulation ring.
Specific scheme is the first sound insulation groove and the second sound insulation groove is semicircle.
Another specific scheme is that valve drives rotation by motor.
The semi-ring that another specific scheme is the first sound insulation ring and the second sound insulation ring is dislocation arrangement.
Compared with prior art, the beneficial effects of the utility model are：
Ceiling type ventilation of room utensil of the present utility model has good soundproof effect, can prevent outside noise from passing through ventilation
Device enters in room.Suitable for places such as household, market, hotel, restaurants.

Fig. 2 is the schematic cross-section of the ventilating opening of the utility model embodiment；
Fig. 3 is the structural representation of the valve of the utility model embodiment.
Wherein：1st, casing；2nd, air intake air diffuser；3rd, ventilating opening；4th, transverse axis；5th, valve；6th, slot；7th, the first sound insulation groove；
8th, the second sound insulation groove；9th, the first sound insulation ring；10th, the second sound insulation ring；11st, acoustical cotton.
Embodiment
With reference to embodiments and its accompanying drawing the utility model is described in further detail.
Embodiment
Referring to Fig. 1 to Fig. 3, noiseproof ceiling type ventilation of room device includes casing 1, impeller and motor, the side of casing 1
On air intake air diffuser 2 is installed, the mounting surface side of casing 1 is provided with ventilating opening 3.
The cross section of ventilating opening 3 is circle, and a transverse axis 4 is provided with along its diametric(al), and one is movably installed with transverse axis 4 with leading to
The circular valve 5 that air port 3 coordinates, the valve 5 is rotated by motor control, to realize the folding of ventilating opening 3.
Valve 5 is opening up a fluting 6 at the both ends of transverse axis 4, and by the segmentation of the edge of valve 5 into two, half is to varus
The first sound insulation groove 7 is changed into, second half flips over into the second sound insulation groove 8, and the first sound insulation groove 7 and the second sound insulation groove 8 are shaped as
It is semicircle.
On the inwall of ventilating opening 3 be provided with the first sound insulation groove 7 coordinate the first sound insulation ring 9, and with the second sound insulation groove 8
The semi-ring that the second sound insulation ring 10 coordinated, the first sound insulation ring 9 and the second sound insulation ring 10 are arranged for dislocation.When valve 5 is in motor
When being closed under driving, the first sound insulation groove 7 is bonded with the first sound insulation ring 9, and the second sound insulation groove 8 is bonded with the second sound insulation ring 10, meanwhile,
Suction is filled with the binding face and the binding face of the second sound insulation groove 8 and the second sound insulation ring 10 of the first sound insulation groove 7 and the first sound insulation ring 9
Sound cotton 11, to realize the noise control effect during closure of valve 5, barrier outside noise is got in by ventilating opening 3.
Preferable implementation example of the present utility model is the foregoing is only, is not limited to the utility model, it is all in this reality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
