DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figures 1 to 3As shown, the small oil-free energy-saving air compressor includes a chassis body 100 and an air intake filter device 200. The chassis body 100 is mainly composed of two boxes 110. An integrally formed cylinder 120 is formed on the top of the box 110. A through hole 121 for carrying the air inlet and outlet of the air compressor is opened on the outer surface of the cylinder 120. The air intake filter device 200 is installed on the top of the chassis body 100 between the two cylinders 120. An integrally formed supporting foot 140 is formed at the bottom of the box 110 to prevent the air compressor from radially shaking, thereby improving the stability and efficiency of the air supply.

[0018] like Figure 1 to Figure 2 As shown, the two boxes 110 of the chassis body 100 are arranged symmetrically with respect to each other, and the opposite end faces of the two boxes 110 are not directly connected, but an opening gap 111 is formed, and the setting of the opening gap 111 facilitates the installation of the air intake filter device 200. A plurality of connecting blocks 130 are formed circumferentially on the outer wall of the box 110 near the opening gap 111, and a bolt hole 131 is opened at the center of each connecting block 130. The two boxes 110 are fixedly connected by bolt connection, so that the length of the air compressor can be flexibly adjusted according to the actual installation and operation requirements.

[0019] To further explain, there are three main forms of heat dissipation for the air compressor of the utility model: first, a plurality of heat sinks arranged at equal intervals are arranged on the top of the cylinder 120, which are responsible for dissipating the heat of the cylinder 120; second, an integrally formed louvered heat sink 112 is formed at the bottom of the box body 110, and the louvered heat sink 112 is a quadrilateral with gaps inside. The motor stator and rotor are arranged in the middle section of the interior of the chassis body 100, which is prone to generate a large amount of heat during operation, and the louvered heat sink 112 plays a role in dissipating the heat of the motor; third, circular fan blade covers 150 are installed at both ends of the chassis body 100, and the circular fan blade cover 150 is equal to the diameter of the chassis body 100. A cooling fan is installed inside the chassis body 100, and airflow is introduced to cool and dissipate heat when the air compressor is running.

[0020] like Figure 3 As shown, the air intake filter device 200 is square in shape as a whole, and its structure is divided into an upper cover 210 and a lower cover 220. The upper cover 210 is provided with connection holes 211 corresponding to the through holes 121 on both sides, and the lower cover 220 is provided with a filter element slot 221 with a circular hole in the center, and a filter element 230 is installed in the filter element slot 221. When the air compressor is running, a negative pressure is formed in the cylinder 120 to inhale air, and the air is filtered through the filter element 230 in the air intake filter device 200, thereby reducing the intrusion of impurities in the air compressor and reducing the water vapor content. The air intake filter device 200 is installed between the cylinders 120, making the overall structure of the air compressor more compact, occupying a smaller area, and convenient for users to operate and install.

[0021] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
