Detailed Description

To achieve the above objects and advantages, the present utility model adopts the technical means and structures, and the features and functions of the preferred embodiments of the present utility model are described in detail below with reference to the accompanying drawings so as to be fully understood.

Referring to fig. 1 to 4, which are perspective views and partial perspective views of a preferred embodiment of the present utility model, it can be clearly seen that the air intake and exhaust device of the present utility model includes:

a body 1;

a first through hole 11 formed at the center of the body 1; and

The second perforations 12 are formed on the body 1 and located around the first perforation 11, one side of each second perforation 12 is provided with an air inlet 121, the other side of each second perforation 12 is provided with an air outlet 122, each second perforation 12 is separated by a plurality of side walls 123, each side wall 123 is spirally inclined, so that the projection of each air inlet 121 and each air outlet 122 is overlapped, each side wall 123 presents an air inlet peak 1231 at the end of the air inlet 121, each side wall 123 presents an air outlet peak 1232 at the end of the air outlet 122, the extending direction of each air inlet peak 1231 from the outer side wall of the first perforation 11 to the inner side wall of the body 1 is pointed, and the extending direction of each air outlet peak 1232 from the outer side wall of the first perforation 11 to the inner side wall of the body 1 is pointed, thereby making the thickness of each side wall 123 extending from the first perforation 11 to the inner side wall of the body 1 identical.

The first through hole 11 is exemplified by a straight hole in the present embodiment.

Wherein, the size of each air inlet 121 and the size of each air outlet 122 are the same.

Wherein the number of the air inlets 121 and the number of the air outlets 122 are the same.

Wherein, the material of air inlet and exhaust device is the metal material.

The air intake and exhaust device can be installed on a vehicle with an internal combustion engine, and the vehicle of the embodiment is exemplified by an automobile, but is not limited to an automobile, and any power tool with an internal combustion engine can be installed.

Referring to fig. 1 to 5, which are schematic perspective views of the preferred embodiment of the present utility model, it can be clearly seen that when the gas a passes through the air inlet and outlet device, the gas a passes through the first through hole 11 and the second through hole 12 respectively, the first through hole 11 is a straight pipe type straight hole, so that the gas a passes through the first through hole 11 to form a direct current C, and when the gas a passes through the second through hole 12, the second through hole 12 is a spiral inclined design, so that when the gas a enters the body 1 from the air inlet 121, part of the gas a impacts the inclined side wall 123 and travels along the side wall 123 toward the air outlet 122, the gas a forms a cyclone by using the inclined side wall 123, and has a whirlwind like a cyclone, and when the cyclone gas B flows out from the air outlet 122, the cyclone gas B can move independently from each other without mutual influence by using the direct current C as a guide, so that the overall gas flow direction is smoother. However, it should be noted that, since the gas inlet 121 has the gas inlet tip 1231, the gas a is split by the cutting at the tip of the gas inlet tip 1231 before entering the second through hole 12, so that the gas a is guided into the second through hole 12 without any resistance, thereby improving the smoothness of the flow of the gas a. In addition, the end of the air outlet 122 is provided with an air outlet tip 1232, so that after the air A flows out, cyclone air B which is compact but not mutually influenced is formed, and is more easily pulled by the direct current C, thereby effectively reducing obstruction. In addition, since the air inlet 121 has the air inlet tip 1231 and the air outlet 122 has the air outlet tip 1232, the shape of the air inlet 121 is identical to the shape of the air outlet 122, so that the user does not need to worry about the stretching problem caused by reverse installation during the installation process, and the advantage of non-directivity is achieved, and even if the installation is performed by a non-professional person, no problem is caused.

Referring to fig. 6 and 7, which are schematic diagrams of the exhaust pipe installation of the preferred embodiment of the present utility model, it is clear from the drawings that the air intake and exhaust device of the present embodiment can be installed on the exhaust pipe 2 of an automobile, and is not limited to the installation position, and the air intake and exhaust device is fixedly installed at the head section of the exhaust pipe 2 by the body 1 and fixedly installed at the tail section of the exhaust pipe 2 by the body 1 and the exhaust pipe 2 illustrated in fig. 6 by the exhaust pipe 2 illustrated in fig. 6, so that when the air intake and exhaust device is installed in the exhaust pipe 2, the air exhausted by the exhaust pipe 2 is positive pressure, so that the exhaust gas generates cyclone air when passing through the air intake and exhaust device, the exhaust pipe 2 can generate liquid, and noise can be reduced at the same time.

Referring to fig. 8, an air inlet end installation schematic diagram of a preferred embodiment of the present utility model is shown, and it is clear from the diagram that the air inlet and outlet device of the present utility model is disposed at the position of the engine air inlet portion 3 and is fixed to the inner wall of the engine air inlet portion 3 by the main body 1, so that when the external air enters the engine, the air inlet and outlet device generates cyclone air, thereby effectively making the air flow of the engine larger and full, making the fuel burn more completely, obviously increasing the engine output power, and finally reducing the carbon dioxide emission.

However, the foregoing description is only illustrative of the preferred embodiments of the present utility model and is not to be construed as limiting the scope of the utility model, as all changes that may be made in the simple form and the details of construction and arrangement of the present utility model, as illustrated in the accompanying drawings, are intended to be included within the scope of the utility model as defined by the appended claims.

Thus, referring to the drawings throughout, the present utility model, when used, does provide the following advantages over conventional techniques:

first, for an engine with an internal combustion engine, because the suction force close to vacuum is generated in the cylinder under the condition of engine intake, the flow speed is fast and the pressure is low according to the law of fluid mechanics, so the air pressure at the air outlet 122 is lower than the air pressure at the air inlet 121, which is beneficial for the air A to be sucked into the cylinder.

Second, when the gas a passes through the air intake and exhaust device, the flow speed of the direct current in the middle is faster than that of the cyclone gas B around, and the air pressure of the direct current is lower than that of the cyclone gas B, so that the cyclone gas B can not scatter and can more intensively rotate when passing through the second perforation 12.

Thirdly, the cyclone gas B belongs to the vortex gas which rapidly rotates, so that the air flow of the engine is larger and plump after the cyclone gas B enters the engine, the fuel oil is combusted more completely, the output power of the engine is obviously increased, and finally the carbon dioxide emission is reduced.

Fourth, the cyclone gas B rotating rapidly can finer fuel oil drops entering the cylinder, combustion efficiency is effectively improved, and exhaust emission is cleaner and more environment-friendly.

Fifth, the user does not need to worry about the derivative problem caused by reverse installation during the installation process, thereby achieving the advantage of no directivity, and no problem exists even if the installation is performed by non-professional persons.

Sixth, when the present embodiment is installed in the exhaust pipe 2, the exhaust gas a passes through the intake and exhaust device because the exhaust gas a is positive pressure, the exhaust pipe 2 can generate liquid and noise can be reduced at the same time.
