Motor with dustproof and breathable device

The present invention provides a motor having a dust venting device that is associated with a motor structure.

A motor is an electrical device that converts electrical energy into mechanical energy and uses mechanical energy to generate kinetic energy to drive other power devices. It can be seen that when the motor is running, its internal operating subsystem operates at high speed to provide driving force. When the motor is running, the internal operation of the motor causes a temperature rise inside. When the internal temperature rises, the internal gas pressure rises. When the motor fails to dispose of the appropriate pressure relief pipe, the internal parts of the motor are subjected to high temperature. The high pressure is damaged and even causes safety hazards in use; in view of this, the creator conceived and further studied and finally created a motor with a dustproof and ventilating device.

The present invention provides a motor with a dustproof and ventilating device, the main purpose of which is to improve the loss of the mechanical damage or the shortening of the life of the motor which is not provided with the pressure relief or cooling mechanism.

To achieve the foregoing objective, the present invention provides a motor having a dustproof and ventilating device, comprising: a motor body; a dust-proof and ventilating device is disposed on the motor body and communicates with the interior of the motor body, and the dust-proof and venting device comprises: a main body, forming a convex stop segment and a through-segment segment, wherein the outer diameter of the convex stop segment is greater than the wear-through An outer diameter of the segment, the through-segment of the body is disposed to be positioned on the through-hole, and an exhaust port and a set of slots are respectively defined at two ends of the body, and the position of the set of slots is corresponding to the position of the joint. And the exhaust port and the set of connecting grooves communicate with each other and penetrate the two ends of the main body, and the pair of connecting grooves and the exhaust port are further formed with abutting edge; a resilient structure is fixed by a side of the elastic plate Connected to a spring, the resilient structure is received in the assembly groove, and the spring is biased against the abutment; a dust-proof gas-permeable sheet is attached to the other side of the elastic plate; One end has a resisting groove, and the plug has a through hole penetrating through the two ends, the plug is inserted into and positioned with the one end of the receiving groove, and the receiving portion of the plug is received The groove correspondingly wears the dustproof gas permeable sheet and the elastic piece, and the dustproof gas permeable sheet is fixed to the tube plug Recepting the groove, and forming a flow space between the set of grooves and the abutting edge to form a communication space connecting the exhaust port; and an outer cover covering the convex section of the main body A gap is formed between the outer cover and the main body to allow gas to flow.

The dust-proof and ventilating device is provided on the motor body, and the dust-proof and ventilating device can be closed to the external communication under the normal state of normal temperature and normal pressure through the arrangement of the elastic absorbing structure, and when the motor body is operated to cause high temperature and high pressure inside, the high temperature is high. The gas can be pressed against the structure that causes the internal structure of the motor body to circulate with the outside, thereby forming a pressure relief and cooling effect, and at the same time, it can prevent the internal parts from rusting due to condensation inside the motor.

At this time, the elastic piece 31 is located between the accommodating groove 51 and the flow space A, and the accommodating groove 51 is closed, and the dust outside the motor body 10 is removed. Or the gas cannot enter the dust venting device; when the motor body 10 is in operation, the motor body 10 generates a high temperature inside, and when the temperature inside the motor body 10 rises, the pressure of the gas inside the motor body 10 increases accordingly. When the horse When the temperature and pressure of the gas inside the body 10 rises, the gas inside the motor body 10 expands. In this case, as shown in Fig. 4, the gas inside the motor body 10 can be located in the motor body. The through hole 52 of the inner plug 50 flows out, and the high-pressure gas passes through the through hole 52 and passes through the dust-proof gas-permeable sheet 40, and then the high-pressure gas pushes against the elastic piece 31 of the elastic structure 30 to make the elastic piece 31. The spring 32 is compressed and disengaged from the receiving groove 51. When the elastic piece 31 is separated from the receiving groove 51, the flow space A is communicated with the receiving groove 51, and the high-pressure gas can pass through the dustproof sheet. 40, after passing through the tolerance groove 51 and the circulation space A, and then flowing through the exhaust port 23 of the main body 20, and finally flowing into the outer cover 60, the outer cover 60 and the gap B of the main body 20 flow out; Release the motor body 10 internal high temperature, high pressure gas, in addition to the purpose of pressure relief, high temperature gas discharge can also effectively reduce the internal temperature of the motor body 10, to achieve temperature cooling, to ensure the safety of the machine, but also to avoid the motor Internal condensation causes the internal parts to rust.
