Abstract
An air volume adjustable noise reduction fan comprises a fan shell (1), a motor (3) and an impeller (2). The motor (3) is fixed on an inner wall of the fan shell (1), the impeller (2) is fixed on a main shaft of the motor (3), one end of a baffle plate (4) is connected with the inner wall of the fan shell (1) in a hinged mode, and the other end of the baffle plate (4) is fixed on an adjusting handle (5). The adjusting handle (5) penetrates an upper wall of the fan shell (1), and the adjusting handle (5) is connected with an upper face of the upper wall of the fan shell (1) in a hinged mode. noise reduction materials fill between an inner wall and an outer wall of an inlet section (11) of the fan shell (1) and between an inner wall and an outer wall of an outlet section (12) of the fan shell (1), and the inner walls of the inlet section (11) and the outlet section (12) are provided with circular holes. The air volume adjustable noise reduction fan has good noise reduction effect, a simple structure and low cost, and at the same time, air volume of the air volume adjustable noise reduction fan can be adjusted.
Description
Technical field:
The utility model relates to the ventilator technical field, more specifically to the adjustable noise reduction fans of a kind of air quantity.
Background technique:
Along with people's is increasingly high to environmental requirement; People have also proposed more highland requirement to the noise that reduces of blower fan; Many existingly noise reduction ventilators are in order to reduce the noise regardless of expense; Even be that special outfit of ventilator reduces noise ground equipment in order to abate the noise, some then spends a lot of thoughts in order to reduce noise on the structure of blower fan, and this just makes the abnormal height of cost of production of noise reduction fans.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and provides a kind of air quantity adjustable noise reduction fans, its good muffling effect, and also its is simple in structure, and cost is lower, and its air quantity can be regulated simultaneously.
The technological solution of the utility model is following:
The noise reduction fans that a kind of air quantity is adjustable; Comprise Blower Housing, motor and impeller; Motor is fixed on the inwall of Blower Housing, and impeller is fixed on the main shaft of motor, and an end of baffle plate is hinged on the inwall of Blower Housing, the other end is fixed on the regulating handle; Said regulating handle passes the upper wall of Blower Housing; And this regulating handle is hinged on the upper wall of upper wall of Blower Housing, be filled with quieter material between the entrance of Blower Housing and the inner and outer wall of outlet section, and the inwall of this entrance and outlet section is distributed with circular hole.
The quieter material of filling between the inner and outer wall of said entrance and outlet section is a glass wool, and the inwall of this entrance and outlet section is made by galvanized sheet.
The top of said Blower Housing forms the electric wire outlet of the electric wire discrepancy of power supply motivation.
Said motor is fixed on the motor cabinet, and said motor is fixed on the inwall of Blower Housing.
The beneficial effect of the utility model is:
1, its good muffling effect, and its is simple in structure, and cost of production is relatively low.
2, it is provided with baffle plate, can regulate air quantity.
Description of drawings:
Fig. 1 is the structural representation of the utility model
Embodiment:
Embodiment: see shown in Figure 1; The noise reduction fans that a kind of air quantity is adjustable comprise Blower Housing 1, motor 3 and impeller 2, and motor 3 is fixed on the inwall of Blower Housing 1; Impeller 2 is fixed on the main shaft of motor 3; One end of baffle plate 4 is hinged on the inwall of Blower Housing 1, the other end is fixed on the regulating handle 5, and said regulating handle 5 passes the upper wall of Blower Housing 1, and this regulating handle 5 is hinged on the upper wall of upper wall of Blower Housing 1; Be filled with quieter material between the entrance 11 of Blower Housing 1 and the inner and outer wall of outlet section 12, and the inwall of this entrance 11 and outlet section 12 is distributed with circular hole.
The quieter material of filling between the inner and outer wall of said entrance 11 and outlet section 12 is a glass wool, and the inwall of this entrance 11 and outlet section 12 is made by galvanized sheet.
The top of said Blower Housing 1 forms the electric wire outlet 13 of the electric wire discrepancy of power supply motivation 3.
Said motor 3 is fixed on the motor cabinet 31, and said motor 3 is fixed on the inwall of Blower Housing 1.
Working principle: be filled with quieter material between the entrance 11 of the utility model Blower Housing 1 and the inner and outer wall of outlet section 12; And the inwall of this entrance 11 and outlet section 12 is distributed with circular hole; The noise circular hole that can distribute and being absorbed like this by quieter material through the inwall that sees through entrance 11 and outlet section 12; And such mode makes the simple in structure of it, do not need structurally to have what the earth to change, and cost is relatively low.
The utility model can be through rotating the angle that regulating handle 5 comes controllable register 4, and this can reach the effect of regulating air quantity.
