Abstract
The utility model relates to a fan, in particular to a fan with an internal vibration-reduction noise-reduction device, which reduces vibration quantity outwardly transferred by the aid of the anti-vibration noise reduction device when the fan runs and further reduces noise of the fan, and belongs to the field of ventilating devices. The fan mainly comprises a shell, a motor, an impeller and a motor frame, wherein the motor and the impeller are connected and are fixed into the shell through the motor frame. The fan is characterized in that the vibration-reduction noise-reduction device is arranged at the connecting position of the motor frame and the shell.
Description
Technical field
The utility model relates to a kind of blower fan, especially a kind of built-in blower fan of vibration damping equipment, and vibratory output that outwards transmits when utilizing vibration and noise reducing device to reduce the blower fan running and then the noise that reduces blower fan belong to the ventilation equipment field.
Background technique
In the building design of modern society, especially, generally all the subtense angle of ventilation system as building can be used for carrying out between the building inside and the external world air exchange to guarantee the pure and fresh of building inner air as the building of public arena.And generally all can be equipped with blower fan in the middle of the ventilation system, blower fan is used for ambient air pumped in the building or with the air in the building and pumps.All blower fans all can produce noise in running.In the middle of the existing fan design; the shape of optimizing the parts such as impeller of blower fan by aerodynamic principle reduces noise; perhaps by the purpose that quieter material reaches noise reduction is set in housing; perhaps between the fixed-site at blower fan and its place, damping device is set; application number as China is 200720198655.X, and name is called the utility model patent of " structure on a kind of blower foundation ring vibration damping and protection basis ".
Summary of the invention
The purpose of this utility model is to provide a kind of blower fan of built-in vibration damping equipment, reduces the vibratory output that blower fan outwards transmits, to reach better noise reduction.
In order to reach above-mentioned purpose of the present utility model, the utility model is achieved through the following technical solutions: a kind of blower fan with vibration damping equipment, mainly form by housing, motor, impeller, motor frame, motor is connected with impeller and is fixed in the housing by the motor frame, it is characterized in that the joint between motor frame and housing is provided with vibration and noise reducing device.
Above-mentioned a kind of blower fan with vibration damping equipment, vibration and noise reducing device wherein is made of elastic material.
The utility model is applied to existing damping technology in the middle of the blower fan, on the basis of existing blower fan technology and in the prerequisite of not obvious increase structural complexity, be issued to better vibration damping and noise reduction, therefore the utlity model has substantive distinguishing features and remarkable progress.

Embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is described.Fig. 1-9 is the same embodiment's of explanation a principle.
Shown in Fig. 1-8, present embodiment is by housing 1,2, motor 3, and impeller 4, motor frame 5, vibration damping equipment 6,7 and some complementary screws are formed, and its middle shell is divided into 1 and 2 two-part, and vibration damping equipment is divided into 6 and 7 two-part.In the present embodiment, the damping pad of vibration damping equipment for adopting rubber material to make
When blower fan is in running order, the mechanical vibration that motor 3 and impeller 4 produce are passed to motor frame 5, transmit in the process of mechanical vibration to housing at motor frame 5, vibration damping equipment absorbs partial vibration energy wherein, thereby reduces to housing and the extraneous vibrational energy that transmits.
As shown in Figure 9, air-flow F enters impeller 4 from the running shaft direction of impeller 4 under the turning effort of impeller 4, thrown away around impeller 4 by impeller 4 then, and then flow to exhaust outlet.
Claims (2)
