Description

Technical Field

[0001] This utility model relates to the technical field of air compressors, and in particular to an intelligent air compressor with an LCD control panel. Background Technology

[0002] An air compressor is a device that converts mechanical energy into gas pressure energy using a piston-type structure. It provides pressure energy for pneumatic tools, pneumatic valves, and pneumatic instruments. Traditional air compressors have relatively simple electrical control functions, only allowing for an automatic shutdown function. They cannot quickly reduce the output air pressure after shutdown, which has certain limitations. Therefore, there is a need for an air compressor with freely adjustable air pressure to meet market demands and improve market competitiveness. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is as follows: an intelligent air compressor with an LCD control panel, comprising a main housing, a secondary housing, a motor, a cylinder assembly, a cylinder head, a side mounting bracket, a panel, a circuit board, a pressure sensor, and a solenoid valve. The secondary housing is detachably connected to the main housing, and the motor is snapped between the main housing and the secondary housing. The cylinder head is sealed to the main housing and / or the secondary housing, and a cylinder assembly connected to the motor output shaft is provided between the main housing and the cylinder head. A side mounting bracket is fixedly connected to the outer side of the main housing and the secondary housing. The panel is detachably connected to the side mounting bracket, and a circuit board for adjustment is provided between the side mounting bracket and the panel. A pressure sensor and a solenoid valve are respectively connected to the cylinder head at the air outlet.

[0004] Using the above technical solution, a circuit board for adjusting the output air pressure is installed on the side of the traditional air compressor. The user sets the required pressure value through the circuit board, and the pressure sensor monitors the air pressure in the outlet chamber. When the air pressure reaches the specified value, the motor stops working. When the air pressure exceeds the specified value, the solenoid valve opens and releases pressure, thereby realizing intelligent control of the air compressor's output air pressure.

[0005] The present invention is further configured such that the main housing / sub-housing is provided with reinforcing ribs distributed in a circular pattern, the side mounting bracket is provided with through holes distributed in a rectangular pattern, and the reinforcing ribs are provided with threaded posts corresponding to the through holes.

[0006] Furthermore, the circuit board includes a control board and a power board. The side mounting bracket has a main control cavity and a power supply cavity. The main control cavity has a first stud for mounting the control board and a first wiring groove for connecting the motor. The power supply cavity has a second stud for mounting the power board and a second wiring groove for connecting an external power supply. The side mounting bracket has a third stud around its perimeter. The panel is connected to the side mounting bracket through the third stud.

[0007] Furthermore, the control panel includes a display screen, a tactile switch, and a rubber pad. The panel has display slots and button sections corresponding to the display screen and the tactile switch, respectively, and the rubber pad is located between the button section and the tactile switch.

[0008] By adopting the above technical solution, the side mounting bracket is L-shaped as a whole. The side mounting bracket is connected to the cylindrical part through through-hole threads, which makes the overall structure of the air compressor uniform and compact, improves the overall aesthetics of the product, and increases market competitiveness.

[0009] The present invention is further configured such that the cylinder head is provided with an intake chamber and an exhaust chamber, and the cylinder assembly includes an eccentric wheel, a piston rod, a cylinder component, a cylinder plate, a one-way pressure plate, and a special-shaped sealing ring. One end of the piston rod is rotatably connected to the output shaft of the motor through the eccentric wheel, and the other end is slidably connected to the cylinder component. The bottom surface of the cylinder plate is sealed to the main housing / sub-housing through the cylinder component, and the top surface of the cylinder plate is sealed to the cylinder head through the special-shaped sealing ring. One-way pressure plates are connected to the cylinder plate at both the intake chamber and the exhaust chamber.

[0010] Using the above technical solution, when the motor rotates, the eccentric wheel structure converts the curvilinear motion into linear motion. When the piston rod moves down, the one-way pressure plate opens the air inlet chamber and closes the air outlet chamber, allowing external gas to enter the cylinder through the air inlet chamber. When the piston rod moves up, the one-way pressure plate closes the air inlet chamber and opens the air outlet chamber, allowing gas in the cylinder to flow out from the air outlet chamber, thus meeting the pressurization requirements of the air compressor.

[0011] The present invention is further configured such that the main housing / sub-housing is provided with an inner circular groove and an outer ring groove coaxially distributed, the outer ring groove is provided with a fourth stud distributed in a circular pattern, the cylinder component is sleeved in the inner circular groove, and the cylinder head is connected to the main housing / sub-housing through the fourth stud.

[0012] Furthermore, the cylinder head is equipped with a pressure sensor for detection at the exhaust chamber, the end face of the main housing / sub-housing is provided with an end cap, the end cap is provided with a mounting hole, the side mounting bracket is provided with a third wire groove, and the connecting wire of the pressure sensor passes through the third wire groove and the mounting hole in sequence and is electrically connected to the circuit board.

[0013] Furthermore, the cylinder head is provided with a solenoid valve for pressure relief at the exhaust chamber, the main housing / sub-housing is provided with a fourth wire groove at the inner circular groove, the cylinder plate is provided with a fifth wire groove, and the connecting wire of the solenoid valve passes through the fifth wire groove, the fourth wire groove and the third wire groove in sequence and is electrically connected to the circuit board.

[0014] By adopting the above technical solution, the connection wires of the solenoid valve and the pressure sensor are hidden inside the main housing, which effectively avoids damage to the connection wires and maintains the stability of the circuit structure when the present invention is held in hand.

[0015] The present invention is further configured such that the end cover is a fan cover, and cooling fans are provided at both ends of the output shaft of the motor. When the motor is working, the cooling fans rotate accordingly, thereby improving the heat dissipation effect of the motor and increasing the service life of the air compressor.

[0016] The present invention is further configured such that the cylinder head is provided with an adapter rod and a handle rod, and the adapter rod is rotatably connected to the handle rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Traditional air compressors have a circuit board on the side for adjusting the output air pressure. Users set the desired pressure value through the circuit board, and the pressure sensor monitors the air pressure in the outlet chamber. When the air pressure reaches the specified value, the motor stops working. When the air pressure exceeds the specified value, the solenoid valve opens and releases pressure, thereby realizing intelligent control of the air compressor's output air pressure.
