Description

Technical Field

[0001] This utility model relates to the technical field of air compressors, and in particular to a connection structure between an air compressor and a cylinder. Background Technology

[0002] Air compressors, as gas compression devices widely used in industrial fields, have the core function of providing power to various pneumatic devices by compressing air. During the operation of air compressors, precise control of air pressure is crucial, directly affecting the operating efficiency and safety of the equipment. Traditional air compressors typically rely on air pressure sensors installed at the output end of the air compressor body to indirectly determine the air pressure status inside the cylinder by monitoring the air pressure value at the output end. However, this design results in data lag, especially when the air compressor starts and stops, as the air pressure value changes abruptly, leading to problems such as low air pressure control accuracy and slow response speed. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: a connection structure between an air compressor and a cylinder, including an air compressor body, a cylinder and a pressure sensor. The air compressor body has a foot at the bottom, and the cylinder is detachably connected to the foot. One side of the cylinder has an air inlet end and a detection end. The detection end is connected to a pressure sensor for feedback of the internal air pressure of the cylinder. The air compressor body includes a main housing and a secondary housing connected together, a side mounting bracket located between the main housing and the secondary housing, and a heat dissipation cover located on the outside of the main housing / secondary housing. The side mounting bracket has a control cavity for connecting a circuit board. The signal line of the pressure sensor passes through the heat dissipation cover and the main housing in sequence and extends into the control cavity.

[0004] By adopting the above technical solution, the air pressure sensor is moved from the output end of the air compressor body to the detection end of the cylinder, which solves the problems of low air pressure detection accuracy, slow response speed and poor anti-interference ability in traditional designs. Moreover, the signal line of the air pressure sensor is always electrically connected to the circuit board, providing reliable technical support for the efficient operation and precise control of the air compressor.

[0005] The present invention is further configured such that the top of the cylinder is provided with an adapter plate for supporting the air compressor body, the upper surfaces of the two sets of adapter plates are coplanar, and the bottom foot is provided with mounting holes for threaded connection of the adapter plate.

[0006] Furthermore, a first buffer pad is provided between the base and the cylinder, and a second buffer pad is provided at the bottom of the cylinder.

[0007] By adopting the above technical solution, the vibration and impact generated during the operation of the air compressor are absorbed through the buffering effect of the first and second buffer pads, thereby improving the operational stability of the equipment and extending its service life.

[0008] The present invention is further configured such that the main housing / sub-housing has a cylindrical portion for mounting the motor and a rectangular portion for accommodating the fan, the rectangular portion having a wire hole on the outside of the cylindrical portion, and the side mounting bracket having an opening slot corresponding to the wire hole.

[0009] Furthermore, the main housing / sub-housing is provided with reinforcing ribs distributed in a circular pattern, and the reinforcing ribs are provided with first studs for connecting the side mounting brackets, which are snapped between the rectangular portions of the main housing and the sub-housing.

[0010] Using the above technical solution, the cylindrical part is used to install the motor, the rectangular part is used to accommodate the fan, and the wire hole is located at the opposite corner of the rectangular part, so that the wire hole is located on the outside of the cylindrical part, making full use of the internal space of the housing and making the main structure of the air compressor compact.

[0011] The present invention is further configured such that the heat dissipation cover is provided with a first countersunk hole and a second countersunk hole arranged in a rectangular pattern around its perimeter, and the rectangular portion is provided with studs corresponding to the first countersunk hole at both ends of the diagonal, and the wire hole corresponds to the second countersunk hole.

[0012] Using the above technical solution, the heat sink cover has no load-bearing requirements. It can be fixed by connecting the two sets of first countersunk holes at its diagonal corners with threads. The remaining second countersunk holes are used for wiring. The first and second countersunk holes are the same size, which makes the heat sink cover look symmetrical and uniform.

[0013] The present invention is further configured such that the heat dissipation cover has an extension for fixing the signal line at the second countersunk hole.

[0014] Using the above technical solution, the signal line of the air pressure sensor passes through the second countersunk hole, and then passes through the wire hole and the slot in sequence to be electrically connected to the circuit board. The heat dissipation cover is provided with an extension that extends to the wire hole. The extension is used to fix the signal line, avoid interference between the fan and the signal line, and improve the stability of the structure.
