2. Description of the Related Art
Taiwan Patent No. M281348 discloses an apparatus that are adapted to supply electricity and pressurized air. The apparatus includes an engine 1, a generator 2, and an air compressor 3. The engine 1 drives the generator 2 and the air compressor 3 simultaneously so as to provide the electricity and pressurized air at the same time. However, the air compressor 3 hinders the apparatus to provide a stable supply of AC power.
Although the air compressor 3 includes a relief valve 34 for relieving pressure from air reservoirs 31, 32 to help reduce the load and the power consumption, the apparatus still presents a problem of providing unsteady supplying of the electricity, in particular, the AC power.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
SUMMARY OF THE INVENTIONThe combination of a generator with an air compressor includes an engine having; a generator, a clutch device, an air compressor and a speed accelerating/decelerating mechanism. The engine includes a throttle disposed at a side thereof. The generator includes a power-generating module axially connected to the engine, an output unit electrically connected to the power-generating module and a shell enclosing the power-generating module. The clutch device is adapted for mounting on the shell and is connected to the power-generating module. The clutch device is comprised of a solenoid valve. The air compressor includes an air-compressing module connected to the clutch device, a plurality of air reservoirs connected to the air-compressing module, and a pressure sensor installed between the air reservoirs and the solenoid valve of the clutch device. The speed accelerating/decelerating mechanism is connected to the throttle of the engine and disposed at a side thereof. The speed accelerating/decelerating mechanism includes a motor electrically connected to the output unit, wherein the motor is adapted for moving the throttle to control the speed of the engine.
It is an objective of the present invention to provide the solenoid valve of the clutch device disengaging with the air compressor when pressure within air reservoirs is not below the preset standard. Accordingly, the air compressor stops functioning and providing pressurized air. Thus, the air compressor is now saving the power of the engine, and enabling the generator to provide a stable supply of AC power.
It is another objective of the present invention to provide the speed accelerating/decelerating mechanism controlling the speed of the motor, wherein the motor is adapted for moving the throttle to control the speed of the engine. Accordingly, the engine can drive the generator with more power, and thereby providing a stable supply of AC power.
Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
For the present disclosure to be easily understood and readily practiced, the present disclosure will now be described for the purpose of illustration not limitation, in conjunction with the following figures, wherein;
Referring to
The clutch device 30 is adapted to mount on the shell 23. As best seen from
The air compressor 40 is disposed at a side of the clutch device 30 and includes an air-compressing module 41 connected to the axle 341 of the clutch device 30, a plurality of air reservoirs 42 for storing the pressurized air and a pressure sensor 43. The pressure sensor 43 is installed between the air reservoirs 42 and the solenoid valve 33 of the clutch device 30. The pressure sensor 43 is adapted for detecting pressure in the air reservoirs 42. If the pressure within the air reservoir 42 is less than the preset standard, the solenoid valve 33 is electrified, and the air compressor 40 is actuated to produce pressurized air.
The speed accelerating/decelerating mechanism 50 is connected to the throttle 11 of the engine 10 and disposed at a side thereof. The speed accelerating/decelerating mechanism 50 serves the purpose of controlling the speed of the engine 10. As best seen from
Referring to
According to the generator and air compressor combination of the present invention, the engine 10 is adapted for driving the generator 20 and the air compressor 40 to provide electricity and pressurized air. The pressurized air is thereafter stored in the air reservoir 42. When the pressure within the air reservoir 42 reaches the preset standard, the air compressor 40 will stop functioning and producing the pressurized air.
When in use with a pneumatic tool, the pressure within the air reservoirs 42 gradually decreases and drops below the preset standard, causing the pressure sensor 43 to electrify the solenoid valve 33 of the clutch device 30. Accordingly, the rotating mechanism 34 is joined with the driving member 333, and the air compressor 40 is actuated to provide pressurized air in order to maintain the pressure within the air reservoir 42 above the standard to ensure stable operation of the pneumatic tool.
An electric tool is readily operable after connecting to the output module 222 of the generator 20. If the power supplied to the tool is not stable, a signal is generated from the output unit 22. The signal is adapted for controlling the motor 52 of the speed accelerating/decelerating mechanism 50, and thereby driving the control arm 54 and the throttle 11 to increase the speed of the engine 10. Accordingly, stable power is provided to the electric tool.
When the use of the electric tool is finished, the motor 52 receives a signal generated from the output unit 22 to cause the engine 10 to slow down to save engine oil.
In one aspect of the combination of a generator with an air compressor in accordance with the present invention, the solenoid valve 33 of the clutch device 30 disengages with the air compressor 40 when pressure within air reservoirs 42 is not below the preset standard. Accordingly, the air compressor 40 stops functioning and providing pressurized air. Thus, the air compressor 40 is now saving the power of the engine 10, and enabling the generator 20 to provide a stable supply of AC power In another aspect of the present invention, the speed accelerating/decelerating mechanism 50 controls the speed of the motor 52, wherein the motor 52 is adapted for moving the throttle 11 to control the speed of the engine 10. Accordingly, the engine 10 can drive the generator 20 with more power, and thereby providing a stable supply of AC power.
While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of invention and the scope of invention is only limited by the scope of accompanying claims.
