[0004] The actual product of the above-mentioned air compressor also includes a controller, and the controller is arranged outside the shell, which is not only abrupt and not simple in appearance, but also causes the air compressor structure to be loose and occupy a larger area. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes an air compressor controller installation structure which makes the air compressor look simple.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an air compressor controller installation structure, the controller includes a panel and a circuit board, the air compressor includes a casing, the casing includes a main body and two cylinder heads fixed on the top of the main body, and the two cylinder heads are arranged side by side, a motor cavity is formed in the main body, a rotor shaft is horizontally arranged in the motor cavity, and axial flow fan blades are fixed at both ends of the rotor shaft, and it is characterized in that the installation structure includes an installation cavity surrounded by the main body and the two cylinder heads, the installation cavity is above the motor cavity and the two are connected, the top of the installation cavity is open, and the above-mentioned panel is horizontally fixed at the open position; a centrifugal fan blade arranged opposite to the installation cavity is fixed in the middle of the rotor shaft; the circuit board is fixed in the installation cavity by a bracket, and the casing is provided with an exhaust channel for discharging the gas introduced into the installation cavity by the centrifugal fan blade to the outside of the casing.

[0007] When in use, the rotor shaft drives the centrifugal fan blades and the axial flow fan blades to operate synchronously; wherein, the axial flow fan blades draw the cold air outside the casing into the casing, and the centrifugal fan blades throw the cold air into the installation cavity, and finally discharge it to the outside of the casing through the exhaust duct.

[0008] The circuit board is arranged in the installation cavity surrounded by the main body and the two cylinder heads, and the panel is arranged at the opening at the top of the installation cavity. This not only makes the controller almost completely contained in the casing, effectively shortening the distance between the various components, making the overall structure of the air compressor more compact and reducing space occupancy, but also makes the controller and the casing completely integrated, with a more beautiful and simple structure.

[0009] At the same time, with the cooperation of axial flow fan blades and centrifugal fan blades, cold air outside the casing is introduced into the installation cavity, so that the circuit board is wrapped in cold air and runs, so as to extend the life and working stability of the controller.

[0010] In the above-mentioned air compressor controller installation structure, a cylinder barrel is vertically fixed in the cylinder head, and a cavity is formed between the inner wall of the cylinder head and the outer wall of the cylinder barrel. The cavity includes a heat-insulating cavity arranged between the installation cavity and the corresponding cylinder barrel, and an exhaust port connected to the corresponding heat-insulating cavity is arranged on the top of the cylinder head. An air inlet is arranged on the side wall of the cylinder head to connect the installation cavity to the corresponding heat-insulating cavity. The above-mentioned exhaust passage consists of the heat-insulating cavity, the exhaust port and the air inlet. The exhaust passage includes a heat-insulating cavity arranged between the installation cavity and the corresponding cylinder barrel, and the gas in the installation cavity enters the heat-insulating cavity through the air inlet and flows upward. In this way, in actual use, the gas forms a gas isolation barrier in the heat-insulating cavity to effectively prevent the heat at the cylinder barrel from flowing toward the controller, further ensuring the life and working stability of the controller.

[0011] In the above-mentioned air compressor controller installation structure, the air inlet is long and horizontally arranged, and the extension direction of the air inlet length is perpendicular to the arrangement direction of the two cylinder heads. The two air inlets are respectively arranged opposite to the two cylinder barrels, and the length of the air inlet is greater than the outer diameter of the cylinder barrel to further prevent the heat on the cylinder barrel from diffusing to the installation cavity.

[0012] In the above-mentioned air compressor controller installation structure, the bracket includes a horizontally arranged long slot body made of heat-conducting material, and the length extension direction of the long slot body is perpendicular to the arrangement direction of the two cylinder heads; the slot of the long slot body is arranged upward, and both ends of the long slot body are open; the above-mentioned circuit board is in the long slot body, and the long slot body includes two long slot walls distributed along the width direction of the long slot body, and the two long slot walls are respectively arranged opposite to the two air inlets. The above-mentioned design is conducive to heat exchange and accelerates the heat dissipation of the circuit board.

[0013] In the above-mentioned air compressor controller installation structure, the long slot wall is composed of a long lower wall arranged obliquely downward and heat dissipation strips 1 and 2 respectively formed on the top surface of the long lower wall. The heat dissipation strips 1 and 2 are both arranged obliquely downward and have different inclination angles. Each long lower wall is provided with a plurality of heat dissipation strips 1 and 2. The number of heat dissipation strips 1 and 2 on the same long lower wall is the same and they are alternately distributed along the length direction of the long slot body. The long slot wall is composed of a long lower wall, heat dissipation strips 1 and 2 all arranged obliquely downward, which not only allows the cold air to be quickly introduced into the air inlet along the inclination of the long slot wall, but also increases the contact area between the cold air and the long slot body, thereby further accelerating the heat dissipation of the circuit board.

[0014] In the above-mentioned air compressor controller installation structure, the bracket also includes a vertically arranged plastic frame, the lower end of the plastic frame extends into the long slot body and the two are fixedly connected, and the upper end of the plastic frame is fixedly connected to the main body; the above-mentioned circuit board is vertically arranged and fixed on the plastic frame. The long slot body is fixedly connected to the main body by the plastic frame on the upper side, so that in actual design, the long slot body can be suspended and there is no obstruction below, which is conducive to the heat dissipation of the long slot body.

[0015] In the above-mentioned air compressor controller installation structure, the outer side walls of the two cylinder heads facing each other constitute the inner side walls of the installation cavity, and there are strip-shaped exhaust gaps between the panel and the two cylinder heads, and the extension direction of the exhaust gap length is perpendicular to the arrangement direction of the two cylinder heads. The exhaust gap can not only speed up the exhaust speed of the gas in the installation cavity, but also form a heat insulation barrier between the panel and the cylinder head, preventing the heat at the cylinder head from spreading toward the panel, and further improving the life of the controller.

[0016] Compared with the prior art, the air compressor controller installation structure has the following advantages:

[0017] 1. The circuit board is set in the installation cavity surrounded by the main body and the two cylinder heads, and the panel is set at the top opening of the installation cavity. This not only makes the controller almost completely contained in the casing, effectively shortens the distance between the components, makes the overall structure of the air compressor more compact, reduces space occupancy, but also makes the controller and the casing completely integrated, and the structure is more beautiful and simple.

[0018] 2. With the cooperation of axial flow fan blades and centrifugal fan blades, the cold air outside the casing is introduced into the installation cavity, so that the circuit board is wrapped in cold air and runs, so as to extend the life and working stability of the controller.

[0019] 3. The exhaust passage includes an insulating cavity arranged between the installation cavity and the corresponding cylinder barrel, and the gas in the installation cavity enters the insulating cavity through the air inlet and flows upward. In this way, in actual use, the gas forms a gas isolation barrier in the insulating cavity to effectively prevent the heat at the cylinder barrel from flowing toward the controller, further ensuring the life and working stability of the controller.

In the actual product, the casing 1 is roughly rectangular, and the length extension direction of the casing 1 is consistent with the arrangement direction of the two cylinder heads 5.

[0027] Among them, a motor cavity 1a is formed in the main body 1c, and a rotor shaft 4 is horizontally rotated in the motor cavity 1a. Axial flow fan blades 6 are fixed at both ends of the rotor shaft 4, and air inlets are densely distributed on the two side walls of the main body 1c distributed along the length direction of the main body 1c.

[0028] like Figure 2 and Figure 3As shown, the air compressor controller installation structure includes an installation cavity 1b surrounded by a main body 1c and two cylinder heads 5, and the installation cavity 1b is located above the motor cavity 1a and the two are connected. The top of the installation cavity 1b is open, and the panel 2 is horizontally fixed at the open position. A centrifugal fan blade 7 arranged opposite to the installation cavity 1b is fixed in the middle of the rotor shaft 4. The circuit board 3 is fixed in the installation cavity 1b by a bracket 8, and the casing 1 is provided with an exhaust channel 9 for discharging the gas introduced into the installation cavity 1b by the centrifugal fan blade 7 to the outside of the casing 1.

[0029] When in use, the rotor shaft 4 drives the centrifugal fan blades 7 and the axial flow fan blades 6 to operate synchronously; wherein, the axial flow fan blades 6 draw the cold air outside the casing 1 into the casing 1, and the centrifugal fan blades 7 throw the cold air into the installation cavity 1b, and finally discharge it to the outside of the casing 1 through the exhaust duct 9.

[0030] The circuit board 3 is arranged in the installation cavity 1b surrounded by the main body 1c and the two cylinder heads 5, and the panel 2 is arranged at the top opening of the installation cavity 1b. This not only makes the controller almost completely contained in the casing 1, effectively shortening the distance between the various components, making the overall structure of the air compressor more compact and reducing space occupancy, but also makes the controller and the casing 11 completely integrated, and the structure is more beautiful and simple.

[0031] At the same time, with the cooperation of the axial flow fan blades 6 and the centrifugal fan blades 7, the cold air outside the casing 1 is introduced into the installation cavity 1b, so that the circuit board 3 is wrapped in the cold air and runs, so as to extend the life and working stability of the controller.

[0032] In this embodiment,

[0033] like Figure 2 and Figure 3 As shown, the structure of the exhaust passage 9 is as follows: a cylinder barrel 10 is vertically fixed in the cylinder head 5, a cavity 11 is formed between the inner wall of the cylinder head 5 and the outer wall of the cylinder barrel 10, the cavity 11 includes an insulating cavity 11a arranged between the installation cavity 1b and the corresponding cylinder barrel 10, an exhaust port 5a connected to the corresponding insulating cavity 11a is provided on the top of the cylinder head 5, and an air inlet 5b is provided on the side wall of the cylinder head 5 to connect the installation cavity 1b to the corresponding insulating cavity 11a.

The exhaust passage 9 includes an insulating chamber 11a arranged between the installation chamber 1b and the corresponding cylinder barrel 10, and the gas in the installation chamber 1b enters the insulating chamber 11a through the air inlet 5b and flows upward. In actual use, the gas forms a gas isolation barrier in the insulating chamber 11a to effectively prevent the heat at the cylinder barrel 10 from flowing toward the controller, thereby further ensuring the life and working stability of the controller.

[0034] Further explanation, each cylinder head 5 is provided with a plurality of exhaust ports 5a, and the plurality of exhaust ports 5a on the same cylinder head 5 are distributed along the width direction of the main body 1c. The air inlet 5b is in the shape of an elongated strip and is arranged horizontally, and the length extension direction of the air inlet 5b is perpendicular to the arrangement direction of the two cylinder heads 5. The two air inlets 5b are arranged directly opposite to the two cylinder barrels 10, and the length of the air inlet 5b is greater than the outer diameter of the cylinder barrel 10, so as to further prevent the heat on the cylinder barrel 10 from diffusing to the installation cavity 1b.

The slot of the long slot body 8a is arranged upward, and both ends of the long slot body 8a are open. The circuit board 3 is in the long slot body 8a, and the long slot body 8a includes two long slot walls distributed along the width direction of the long slot body 8a, and the two long slot walls are respectively arranged opposite to the two air inlets 5b.

Each long lower wall 8b is provided with a plurality of heat dissipation strips 1 8c and a plurality of heat dissipation strips 2 8d.

The long slot wall is composed of a long lower wall 8b, a heat dissipation strip 1 8c and a heat dissipation strip 2 8d all arranged obliquely downward, which not only allows the cold air to be quickly introduced into the air inlet along the inclination of the long slot wall, but also increases the contact area between the cold air and the long slot body 8a, thereby further accelerating the heat dissipation of the circuit board 3. In actual products, the long slot body 8a is an integrated structure.
