Description

Air pump device

This creation is an air compressor device, which includes a box body and an air compressor. The air compressor is housed in the box body. The air guiding mechanism installed in the box body can pivotally connect the motor of the air compressor. The radiating fan blade frame is covered inside. The diversion mechanism can concentrate and divert the air flow, and quickly guide the air flow generated by the operation of the radiating fan to the entire body of the air compressor, so that the body is not easy to accumulate. The heat can exert the highest pumping efficiency, and can also extend the service life of the air compressor at the same time.

Press, the air compressor is a device that can inflate items to be inflated. It is generally widely used for inflating air cushions and tires. Because the air compressor is small in size, it can be easily carried and placed. It can also be used by a portable DC power supply. Or it can be connected to the car cigarette lighter socket, which can provide the power source of the air compressor, which is very simple and convenient in operation and use. Generally speaking, the main composition of the conventional air compressor device is to use a box to install the air compressor inside. The air compressor uses a motor to drive a piston to perform reciprocating compression in the cylinder. , The compressed air can be transmitted to the objects to be inflated to achieve the purpose of inflation. When the motor drives the piston body to reciprocate in the cylinder, the high-temperature heat generated by it will accumulate in the motor housing. The high temperature is also accumulated in the box and cannot be quickly dissipated and released outside the box. The reason for the high temperature This phenomenon is due to the fact that when the motor starts the rotor operation, the armature, which includes the structure of the armature core, armature winding, commutator, etc., or collectively referred to as the rotor ) Will generate high heat, which will cause the temperature to rise, especially the contact friction between the commutator and the carbon brush in the armature, which not only causes the entire armature to generate high heat. The high heat not only makes the carbon brush prone to carbon deposits and affects the flow of current, but the high heat accumulated in the motor housing also affects the magnetic force of the magnet installed on the inner peripheral wall of the housing, which will cause the magnetic force of the magnet to decrease, and consequently It also results in a gradual decrease in the operating efficiency of the motor. Looking at the current first-aid device for car tire damage that uses low-power motors in air compressor equipment, that is to say, it can provide first-aid rubber tire repair and first-aid device for inflation after tire damage. However, due to the traffic laws of some countries It is stipulated that when car drivers experience tire damage while driving on the highway, the driver must complete the repair and drive the car away from the accident site within the time limit specified by the law to prevent the car from chasing behind and to protect the safety of all drivers Therefore, the motor used needs to quickly deal with the tire damage in a short time. During the rapid rotation of the motor, most of the high heat generated during the rotation of the rotor is accumulated inside the motor housing, and the heat cannot be effectively dissipated. When the temperature rises to a certain level, the insulation of the enameled coil in the armature will be destroyed, which will cause the short circuit of the enameled coil and burn down the entire motor. To derive other dangers. On the other hand, the air compressor is housed in the box. The current assembly method only uses the frame or partition of the box to support the air compressor. In fact, the conventional box does not have an additional design. With a structure to dissipate heat to the entire body of the air compressor, the traditional design of the conventional box body is still easy to accumulate the high heat generated during the operation of the air compressor, and cannot assist the air compressor to dissipate heat and overcome the latent air compressor operation. Loss of efficiency degradation and damage.

The main purpose of this creation is to provide an air compressor device, which includes a box body and an air compressor. The air compressor is housed in the box body. The heat dissipation fan blade frame pivoted by the motor is covered inside, and the air flow generated by the operation of the heat dissipation fan blade is quickly guided to the entire body of the air compressor, so that the body can exert the highest pumping efficiency because it is not easy to accumulate heat. It can also extend the service life of the air compressor at the same time.

Another main purpose of this creation is to provide an air compressor device. The box body is equipped with a diversion mechanism that can concentrate and divert the air flow, and quickly guide the air flow generated by the rotation of the heat dissipation fan blades pivoted by the motor. To the whole body of the air compressor, the body can exert the highest air pumping efficiency because it is not easy to accumulate heat, and it can also extend the service life of the air compressor at the same time.
