Description

[Technical Field]

[0001] The present invention relates to an air compressor structure. [Background technology]

[0002] The main structure of an air compressor is that a motor drives a piston, which performs a reciprocating compression motion inside a cylinder, and the compressed air can be used to fill an object to be expanded that is connected to it.

[0003] As is well known, the temperature of gas increases during compression. At the same time, in the above-mentioned air compressor structure, the intermittent motion of the piston causes the transmission of air pressure to become unstable. In addition, the intermittent pressure shock waves cause the pointer of the pressure gauge to vibrate, resulting in a discrepancy between the pressure value indicated by the pressure gauge and the actual pressure value at the outlet.

[0004] Therefore, how to provide a simple structure while taking the above requirements into consideration is a problem that needs to be considered and solved by relevant engineers. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention provides a compact air compressor structure that combines structural sealing and air pressure stability. [Means for solving the problem]

[0006] The air compressor structure of the present invention includes a cylinder, a piston, and a cylinder head. The piston is coupled to the cylinder and reciprocates to generate compressed air. The cylinder head is detachably attached to the cylinder. The cylinder head has an air reservoir and an air outlet, and the air reservoir communicates between the cylinder and the air outlet to receive compressed air and discharge the compressed air from the air compressor structure via the air outlet. [Effects of the Invention]

[0007] Based on the above, the air compressor structure has an air storage chamber and an air outlet arranged in the cylinder head, which receives compressed air from the cylinder and discharges it through the air outlet through the rear of the air storage chamber. This gives the cylinder head an integrated structure that not only engages and covers the cylinder that receives the compressed air, but also uses the air storage chamber within it as a buffer area for the compressed air, achieving both structural sealing and air pressure stability.

[0009] FIG. 1 is a schematic diagram of an air compressor structure according to one embodiment of the present invention. FIG. 2 is an exploded schematic diagram of some components of the air compressor structure shown in FIG. 1. Here, for ease of explanation of the components, Cartesian coordinates X, Y, and Z are simultaneously provided. Referring to FIGS. 1 and 2 simultaneously, in this embodiment, the air compressor structure 100 includes a cylinder 110, a cylinder head 120, a piston 130, a transmission mechanism 140, a motor 150, a pressure gauge 160, and a pressure relief valve 170. The cylinder head 120 is detachably attached to the cylinder 110. The transmission mechanism 140 is connected between the motor 150 and the lower end of the piston 130. The upper end of the piston 130 is movably coupled within the cylinder 110. The motor 150 drives the piston 130 via the transmission mechanism 140 to reciprocate within the cylinder 110 to generate compressed air. As the upper end of the piston 130 reciprocates, it moves toward or away from the cylinder head 120. As the piston 130 advances to compress the air, its upper end simultaneously moves toward the cylinder head 120, pushing the compressed air from the cylinder 110 into the cylinder head 120. When the piston 130 returns to its original position, the upper end of the piston 130 separates from the cylinder head 120, and air from the external environment flows into the cylinder 110. The cylinder head 120 has an air reservoir and an air outlet 123. After the piston 130 generates compressed air within the cylinder 110, the compressed air is pushed by the piston 130 into the air reservoir as described above, passes through the cylinder head 120, and then exits the air compressor structure 100 through the air outlet 123. Simply put, the air reservoir in the cylinder head 120 serves as a temporary storage area for the compressed air before it is discharged from the air compressor structure 100.

[0010] 3 and 4 are local cross-sectional views of different portions of the cylinder head. Referring simultaneously to FIGS. 2 to 4, the cylinder head 120 of this embodiment is an integrated structure consisting of a cover body 121 and a carrier 122. The cover body 121 engages with or disengages from the cylinder 110. The carrier 122 is structurally connected to the cover body 121 and has an air outlet 123. The cover body 121 and the cylinder 110 are connected to each other and receive compressed air. More specifically, the cover body 121 has a first chamber 121c, and the carrier 122 has a second chamber 122b. The first chamber 121c is connected to the second chamber 122b via an opening 122a, and the opposite side of the first chamber 121c is in communication with the cylinder 110. The second chamber 122b is connected to the air outlet 123 via the opening 123a, so that the second chamber 122b communicates between the first chamber 121c and the air outlet 123. After the piston 130 generates compressed air in the cylinder 110, as described above, the compressed air is pushed by the piston 130 into the cylinder head 120. As shown in Figure 2, the compressed air passes through the first chamber 121c, the opening 122a, the second chamber 122b, and the opening 123a in that order, and reaches the air outlet 123 to be discharged.

[0011] From this, it is clear that the cylinder head 120 not only functions as a connecting member between the cylinder 110 and the object to be expanded (not shown), but also as a temporary retention area for the compressed air. More specifically, the carrier 122 has an L-shaped profile, and the second chamber 122b has a turning point, thereby extending the retention time of the compressed air in the second chamber 122b. In this way, when the piston 130 intermittently reciprocates, compressed air still remains in the second chamber 122b and the first chamber 122c, so the unstable air pressure caused by the intermittence does not directly affect the compressed air discharged from the air outlet 123. Furthermore, as the operating time of the air compressor structure 100 increases or friction occurs between the piston 130 and the cylinder 110, the compressed air inevitably absorbs heat from the device. Because the cylinder head 120 has a first chamber 121c and a second chamber 122b (which together mainly form the air storage chamber) for storing compressed air, heat can be dissipated through the structure itself (carrier 122 and cover body 121) while the compressed air is stored in the air storage chamber, preventing the heat of the compressed air from affecting the object to be expanded.

[0012] 1, 2 or 4, the pressure gauge 160 of the air compressor structure 100 of this embodiment is disposed in the carrier 122 to sense the air pressure in the second chamber 122b, and the scale of the pressure gauge 160 is located on the surface of the carrier 122. Therefore, the cylinder head 120 allows the user to know the air pressure value of the air reservoir through the built-in pressure gauge 160. Furthermore, the pressure relief valve 170 of this embodiment is disposed in the carrier 122 and communicates with the second chamber 122b, so that the user can check the pressure gauge 160 and determine whether to operate the pressure relief valve 170 accordingly so that the pressure of the compressed air in the air reservoir reaches a required level.

[0013] FIG. 5 is a schematic diagram of the cylinder head and cylinder assembly. Referring to FIGS. 2 and 5 simultaneously, in this embodiment, the cover body 121 and the cylinder 110 share a central axis CZ. The inner bottom edge of the cover 121 is provided with multiple notches 121a and multiple stoppers 121b, which are staggered around the central axis CZ. The outer cylindrical surface 111 of the cylinder 110 is provided with multiple protrusions 112, which are arranged around the central axis CZ and correspond to the notches 121a and stoppers 121b. Each protrusion 121b passes through the corresponding notch 121a and moves into the first chamber 121c of the cover body 121. When the cover body 121 and the cylinder 110 rotate relative to each other, each protrusion 112 moves into and engages with the corresponding stopper 121b. Here, the distance of the convex portion 112 from the central axis CZ is smaller than the distance of the notch 121a from the central axis CZ, and the convex portion 112 and the notch 121a are located on the same plane (for example, the XY plane). This plane (XY plane) is a normal plane to the central axis CZ (or regarded as the Z axis).

[0014] In this manner, during the process of assembling the cylinder head 120 and the cylinder 110, the protrusion 121b first moves along path L1 into the first chamber 121c of the cover body 121. Then, as shown by the rotation arrow in FIG. 5, the cylinder head 120 and the cylinder 110 are driven to rotate relatively along the central axis CZ. This is equivalent to the protrusion 112 moving along path L2. The protrusion 112 and the stopper 121b engage to complete the assembly. The user can then smoothly separate the cylinder head 120 and the cylinder 110 along the central axis CZ by simply rotating the cylinder head 120 and the cylinder 110 in the reverse direction along path L2. Here, FIG. 5 shows the state before assembly, and FIG. 2 corresponds to the state after assembly.

[0015] In summary, in the above-described embodiment of the present invention, the air compressor structure has an air reservoir and an air outlet disposed in the cylinder head, which receives compressed air from the cylinder and discharges it through the rear of the air reservoir through the air outlet. This allows the cylinder head to have an integrated structure, which not only engages and covers the cylinder receiving the compressed air, but also uses the air reservoir as a buffer area for the compressed air, thereby achieving both structural sealing and air pressure stability, thereby overcoming the impact of intermittent pressure generated by the reciprocating motion of the piston on the pressure gauge structure. At the same time, the buffer area allows the compressed gas to dissipate heat through the structure surrounding the buffer area, thereby reducing the temperature rise caused by the air compression process.

[0016] In one embodiment, the cylinder head and the cylinder are mounted, engaged, and dismounted in a rotational manner by the relative relationship of the protrusion, the notch, and the stopper, which provides a simple and practical method for assembling the cylinder head and the cylinder, facilitating disassembly and assembly, making the air compressor structure compact as described above, and achieving the aforementioned effects.
