DETAILED DESCRIPTION

[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0024] Embodiments of the present invention: Figure 1-Figure 8 As shown, an electric air compressor with an integrated air inlet and outlet system includes an electric air compressor body 1, an air filter bracket 3 and a heat dissipation steel pipe bracket 4 are installed on the lower bracket 2 of the electric air compressor body 1, an air filter 5 is installed on the air filter bracket 3, a heat dissipation steel pipe 6 is installed on the heat dissipation steel pipe bracket 4, an air outlet end of the air filter 5 is connected to the air inlet pipe of the electric air compressor body 1 through an air filter hose 7, and one end of the heat dissipation steel pipe 6 is connected to the air outlet pipe of the electric air compressor body 1.

[0025] The electric air compressor body 1 and the air filter 5 in this embodiment are existing products and can be obtained by purchase. The specific structure and working principle of the electric air compressor body 1 and the air filter 5 will not be repeated in this embodiment.

[0026] By installing the air filter bracket 3 and the heat dissipation steel pipe bracket 4 on the lower bracket 2 of the electric air compressor body 1, the air filter 5 and the heat dissipation steel pipe 6 are fixed on the lower bracket 2, which effectively saves the space occupied by the air filter 5 and the heat dissipation steel pipe 6, and makes the air filter 5 and the heat dissipation steel pipe 6 easy to install and disassemble. Since the air filter 5 and the heat dissipation steel pipe 6 are arranged close to the electric air compressor body 1, the air filter hose 7 only needs a shorter length, saving the use of materials. The heat dissipation steel pipe 6 can be directly connected to the outlet pipe of the electric air compressor body 1, which saves the use of one high-temperature and high-pressure hose compared with the prior art, effectively reducing the cost.

[0027] In a specific implementation, the air filter bracket 3 and the heat dissipation steel pipe bracket 4 are located on the left and right sides of the electric air compressor body 1 .

[0028] Among them, the air filter bracket 3 includes a first horizontal mounting plate 17 and an air filter fixing plate 8, the air filter fixing plate 8 is an "L"-shaped plate, the first horizontal mounting plate 17 and the air filter fixing plate 8 are an integrated structure, two first mounting holes 9 are opened on the first horizontal mounting plate 17, and two second mounting holes 10 are opened on the air filter fixing plate 8.

[0029] The air filter fixing plate 8 is designed to be "L"-shaped, so that the air filter 5 can be located at one end of the electric air compressor body 1, so that the middle part of the electric air compressor body 1 is not blocked, which facilitates the installation of the air filter hose 7.

[0030] The air filter 5 has a mounting bracket, and the mounting hole on the mounting bracket on the air filter 5 is opposite to the two second mounting holes 10 on the air filter fixing plate 8, and the mounting bracket on the air filter 5 is fixed to the air filter fixing plate 8 by two bolt assemblies. The positions of the two first mounting holes 9 on the first horizontal mounting plate 17 are opposite to the positions of the two mounting holes on one side of the lower bracket 2, and are fixedly connected by two bolt assemblies.

[0031] There is an angle between the first horizontal mounting plate 17 and the air filter fixing plate 8, and the angle is greater than 90°. However, the angle should not be too large. If the angle is too large, the occupied space will be increased. It is only necessary to ensure that a certain gap is maintained between the air filter fixing plate 8 and the side of the electric air compressor body 1, because the electric air compressor body 1 will vibrate when working, and it is necessary to ensure that the electric air compressor body 1 does not contact the air filter fixing plate 8 when vibrating.

[0032] The air filter hose 7 has four bending portions 11, and the bending angles of the four bending portions 11 are all ≥90°. When the bending angles of the bending portions 11 are ≥90°, the air intake resistance of the electric air compressor body 1 can be reduced, thereby ensuring smooth air intake.

[0033] The heat dissipation steel pipe bracket 4 includes a second horizontal mounting plate 12 and a heat dissipation steel pipe fixing plate 13. The second horizontal mounting plate 12 and the heat dissipation steel pipe fixing plate 13 are an integrated structure. The heat dissipation steel pipe fixing plate 13 is a "convex" shaped plate. Two groups of third mounting holes 14 are opened on the heat dissipation steel pipe fixing plate 13, and each group is composed of two third mounting holes 14. Two fourth mounting holes 15 are opened on the second horizontal mounting plate 12.

[0034] Two pipe clamps 16 are installed on the heat dissipation steel pipe 6 , and the two pipe clamps 16 are fixed on the heat dissipation steel pipe fixing plate 13 by bolt assemblies respectively.

[0035] The pipe clamp 16 is a prior art. The two groups of third mounting holes 14 on the heat dissipation steel pipe fixing plate 13 are used to install two pipe clamps 16. Each pipe clamp 16 has two mounting holes. The mounting holes on the pipe clamp 16 are opposite to the two third mounting holes 14 of the same group and are fixedly connected using a bolt assembly.

[0036] The two fourth mounting holes 15 on the second horizontal mounting plate 12 are opposite to the two mounting holes on the other side of the lower bracket 2 and are fixedly connected by a bolt assembly.

[0037] There is an angle between the second horizontal mounting plate 12 and the heat dissipation steel pipe fixing plate 13, and the angle is greater than 90°. The specific value of the angle between the second horizontal mounting plate 12 and the heat dissipation steel pipe fixing plate 13 can be set according to actual needs, and it is also necessary to ensure that the electric air compressor body 1 will not contact the heat dissipation steel pipe fixing plate 13 when vibrating during operation.

[0038] The upper end of the heat dissipation steel pipe 6 is connected to the air outlet pipe of the electric air compressor body 1, and the lower end of the heat dissipation steel pipe 6 is a reserved chassis interface. Considering that the compressed air discharged from the electric air compressor body 1 is mixed with oil and water, the vertical height is gradually reduced from one end where the heat dissipation steel pipe 6 is connected to the electric air compressor body 1 to the other end to ensure that oil and water are not retained in the heat dissipation steel pipe 6. At the same time, the heat dissipation steel pipe 6 has a spiral structure, which is compactly arranged and occupies a small space.

[0039] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
