Description

Portable Blowing and Suction Air Compressor Cross-reference with related applications The present application claims priority to Taiwan Patent Application No. 113120437 filed on June 3, 2024. The entirety of the aforementioned patent application is incorporated by reference into this specification and constitutes part of this specification. Technology field The present disclosure relates to air compressors, and in particular to portable blower and intake air compressors. An air compressor is a device capable of inflating objects and is widely used to inflate air mattresses and tires. In addition to efforts to reduce the size to improve the portability of air compressors, adjustments to the power supply system are required. For example, the conventional operating method, which requires fixing and connecting to an external power source via cables, is being replaced by a method of installing a battery directly on the air compressor. However, due to advancements and replacements in battery technology, there is a problem of insufficient applicability between new batteries and older devices, and between older batteries and new devices. Furthermore, since the aforementioned expansion process is merely a part of the stroke of the air compressor's piston, it is evident that it is impossible to show or utilize the movement of the air compressor's piston solely as an expansion device. The attached drawings are provided for a deeper understanding of the present disclosure and are included in and constitute part of this specification. The drawings illustrate exemplary embodiments of the present disclosure and serve to explain the principles of the present disclosure together with the detailed description. FIG. 1 is a schematic diagram of an air compressor according to one embodiment of the present disclosure. FIG. 2 is an exploded view of the main body of the air compressor of FIG. 1. Figure 3 is an exploded view of the air compressor module of Figure 2. FIGS. 4a and FIGS. 4b are drawings illustrating different states of the air compressor module, respectively. FIG. 4c is a partial enlarged view of the air compressor module of FIG. 4a located at the second stage of the piston. FIG. 5a is a schematic diagram of a piston according to another embodiment of the present disclosure. FIG. 5b is a schematic diagram of the part of FIG. 5a of other states. FIGS. 6 to 8 are schematic diagrams of pistons of other embodiments of the present disclosure. FIGS. 9a and 9b are schematic diagrams of an air compressor according to another embodiment of the present disclosure viewed from different angles. FIG. 10 is a schematic diagram of an air compressor according to another embodiment of the present disclosure. FIG. 1 is a schematic diagram of an air compressor according to one embodiment of the present disclosure. FIG. 2 is an exploded view of the main body of the air compressor of FIG. 1. Refer to FIG. 1 and FIG. 2 simultaneously. In this embodiment, the air compressor includes a main body (10A) and a battery (20). The battery (20) is detachably inserted into a slot on the outside of the main body (10A) and connected to an electronic module inside it, thereby allowing the air compressor to be portable without being limited to an external power source that requires connection at a fixed position. As shown in FIG. 2, the main body (10A) includes housings (13 and 14), a circuit board (15), a partition (16), and an air compressor module (100). These components are assembled together with multiple screws (SC), and the cylinder (140) of the air compressor module (100) has an air inlet pipe (142) and an air outlet pipe (143) to form the housing (13 and 14) together with the air inlet (12) and the air outlet (11). FIG. 3 is an exploded view of the air compressor module of FIG. 2. Refer to FIG. 3. In this embodiment, the air compressor module (100) includes a motor (110), a piston (120), a sealing member (130), a cylinder (140), a first check valve (151), and a second check valve (152). The piston (120) has a first stage (E1) and a second stage (E2) opposite each other. The first stage (E1) is connected to the motor (110) through a transmission mechanism. Here, the transmission mechanism has a first gear (TS1) and a second gear (TS2). A first gear (TS1) is positioned on a motor (110), and a second gear (TS2) is pivotally mounted on a bracket (144) of a cylinder (140). A second stage (E2) of a piston (120) is movably coupled to the cylinder (140), and a first stage (E1) of a piston (120) is pivotally connected to an eccentric position of the second gear (TS2). The first gear (TS1) passes through the bracket (144) and, as a result of assembling the motor (110) to the bracket (144), engages with the second gear (TS2). Accordingly, the motor (110) can smoothly drive the piston (120) to reciprocate within the cylinder (140) through the first gear (TS1) and the second gear (TS2). FIGS. 4a and FIGS. 4b illustrate different states of an air compressor
