Description

Intake and exhaust device of vehicle

Technical Field

The utility model provides an air intake and exhaust device, particularly an air intake and exhaust device for a vehicle that can increase the flow rate of gas entering or discharging from a vehicle and has no directionality during installation.

Background technique

For example, the prior art "vortex duct device" is a columnar body including: an air inlet end; an air outlet end, which is correspondingly arranged on the air inlet of the mechanical device; a direct current air hole, which is a straight long hole, penetrating at the axis between the two ends; a plurality of swirl air holes, which are arranged in an annular manner and penetrate between the air inlet end and the air outlet end at intervals. The hole shape of the swirl air hole is an annular hole that is flush with the end face of the air outlet end and is covered with the end face, and gradually presents a vortex shape toward the air inlet end, and the inner ring wall surface gradually tilts in an arc shape until it passes through the air inlet end and presents a streamline hole shape in the shape of a vortex fan. The opening projections of each swirl air hole at both ends partially overlap, so that the design can guide the airflow to enter in a spiral form, thereby greatly increasing the force of the gas entering the combustion chamber.

However, when the above-mentioned vortex tube device is used, it does have the following problems and shortcomings that need to be improved:

Although the patent discloses a method that can increase the force of gas entering the combustion chamber, during the installation process, for unfamiliar people, the direction of installation often occurs, causing the effect to be unable to be displayed, and even damaging the internal combustion engine.

Therefore, how to solve the above-mentioned common problems and shortcomings is the direction that the creator of the present invention and related manufacturers engaged in this industry want to research and improve.

Utility Model Content

In view of the above shortcomings, the applicant of this utility model collected relevant information, evaluated and considered many aspects, and used his many years of experience in this industry, and through continuous attempts and modifications, he designed this kind of device that can increase the entry or discharge of vehicle gases. The flow rate is high and the installation is non-directional for the intake and exhaust devices of vehicles.

The main purpose of this utility model is to prevent the user from having the problem of reverse installation when installing. No matter which direction it is installed, it can effectively increase the flow rate of gas entering or exiting.

The structure of the utility model that can achieve the above main purpose includes a body, a first through hole, and a plurality of second through holes. The first through hole is formed at the center of the body, the second through hole is formed on the body and is located around the first through hole, and the second through hole is formed on the body. There is an air inlet on one side of the perforation and an air outlet on the other side. The second perforation is isolated by several side walls, and each side wall is spirally inclined, so that the projections of each air inlet and each air outlet partially overlap. , the side wall has an air inlet tip top at the air inlet end, the air inlet tip top is pointed in the extending direction from the first perforated outer wall to the body inner wall, and the side wall has an air outlet tip top at the air outlet end. , the extending direction of the top of the air outlet tip from the outer wall of the first perforation to the inner wall of the body is all pointed, so that the thickness of each side wall extending from the first perforation to the inner wall of the body is the same.

When the user wants to install the air intake and exhaust device of this case on a vehicle, since the air inlet and the air outlet have an air inlet tip top and an air outlet tip top respectively, it means that the air inlet and the air outlet have the same shape, so that during installation When the gas passes through the first and second perforations, both ends of the body can be installed in any direction along the path of the gas channel without directionality. When the gas passes through the first and second perforations, direct current and vortex (that is, cyclone gas) will be generated, which effectively increases the gas flow. The flow rate into or out can achieve more complete fuel combustion in the engine, increase engine output power, reduce carbon dioxide emissions, and reduce noise.

With the above technology, we can overcome the problem of commonly used vortex duct devices. For unfamiliar people, the installation direction often occurs in the opposite direction, causing the effect to be unable to be displayed, and even damaging the internal combustion engine. The above-mentioned advantages of the present invention.

Detailed ways

In order to achieve the above objects and effects, the technical means and structures adopted by the present utility model are described in detail below with reference to the accompanying drawings for a complete understanding of the characteristics and functions of the preferred embodiments of the present utility model.

Please refer to Figures 1 to 4, which are three-dimensional views to three-dimensional partial perspective views of preferred embodiments of the present utility model. It can be clearly seen from the figures that the air intake and exhaust device of the present utility model includes:

Body 1;

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

A plurality of second through holes 12 are formed on the body 1 and are located around the first through hole 11. Each of the second through holes 12 has an air inlet 121 on one side and an air outlet 122 on the other side. Each of the second through holes 12 is separated by a plurality of side walls 123. Each of the side walls 123 is spirally inclined so that the projections of each of the air inlets 121 and each of the air outlets 122 partially overlap. Each of the side walls 123 has an air inlet at the end of the air inlet 121. The pointed top portion 1231, each of the side walls 123 has an outlet pointed top portion 1232 at the end of the outlet port 122, the air inlet pointed top portion 1231 is pointed in the extension direction from the outer wall of the first through hole 11 to the inner wall of the main body 1, and the air outlet pointed top portion 1232 is pointed in the extension direction from the outer wall of the first through hole 11 to the inner wall of the main body 1, thereby making the thickness of each of the side walls 123 extending from the first through hole 11 to the inner wall of the main body 1 the same.

The first through hole 11 in this embodiment is a straight hole.

The sizes of the air inlets 121 and the air outlets 122 are the same.

The number of each air inlet 121 and each air outlet 122 is the same.

Wherein, the material of the intake and exhaust device is metal.

The air intake and exhaust device can be installed on a vehicle with an internal combustion engine. The vehicle in this embodiment is a car. However, it is not limited to a car. Any power tool with an internal combustion engine can be installed.

Please also refer to Figures 1 to 5, which are perspective views and fluid flow diagrams of preferred embodiments of the present utility model. It can be clearly seen from the figures that when gas A passes through the intake and exhaust device of this case, gas A will separate Through the first perforation 11 and the second perforation 12, the first perforation 11 is a straight tube type straight hole, so that after the gas A passes through the first perforation 11, a direct flow C is formed, and when the gas A passes through the second perforation 12, due to The second through hole 12 has a spiral inclined design, so that when the gas A enters the body 1 from the air inlet 121, part of the gas A will hit the inclined side wall 123 and travel along the side wall 123 toward the air outlet 122. The gas A The inclined side wall 123 is used to form a cyclone, which is like a tornado-like vortex phenomenon. When the cyclone gas B flows out from the air outlet 122, the above-mentioned direct current C is used as a guide, so that the cyclone gas B can communicate with each other. They move forward independently without affecting each other, making the overall gas flow smoother. However, it is worth mentioning that since the air inlet 121 has an air inlet tip 1231 , the gas A will be cut by the tip of the air inlet tip 1231 before entering the second through hole 12 , causing the gas A to shunt. Without any resistance, it is guided to the second through hole 12 to improve the smoothness of the flow of gas A. In addition, there is an air outlet tip 1232 at the end of the air outlet 122, so that after the gas A flows out, a tight but non-interfering cyclone gas B is formed, and is more easily pulled by the direct current C, effectively reducing the obstruction. In addition, since the air inlet 121 has an air inlet tip top 1231 and the air outlet 122 has an air outlet tip top 1232, it means that the shapes of the air inlet 121 end and the air outlet 122 end are the same. In this way, the user does not need to Worrying about extension problems caused by reverse installation, it achieves a non-directional advantage. Even if it is installed by non-professionals, there will be no problems.

Please refer to Figures 6 and 7, which are exhaust pipe installation schematic diagrams 1 and 2 of preferred embodiments of the utility model. It can be clearly seen from the figures that the air intake and exhaust device of this embodiment can be installed on the exhaust pipe 2 of a car, and its installation position is not limited. With the exhaust pipe 2 demonstrated in Figure 6, the air intake and exhaust device of this case is fixedly arranged at the head section of the exhaust pipe 2 with the main body 1, and the main body 1 is fixed to the exhaust pipe 2. With the exhaust pipe 2 demonstrated in Figure 7, the air intake and exhaust device of this case is fixedly arranged at the tail section of the exhaust pipe 2 with the main body 1. Therefore, when the air intake and exhaust device of this case is arranged in the exhaust pipe 2, because the gas discharged from the exhaust pipe 2 is positive pressure, the exhaust gas generates cyclone gas when passing through the air intake and exhaust device, so that the exhaust pipe 2 can produce liquid and can also reduce noise at the same time.

Please refer to Figure 8, which is a schematic diagram of the installation of the air inlet end of a preferred embodiment of the present utility model. It can be clearly seen from the figure that the difference between this embodiment and the above-mentioned embodiment is that the air intake and exhaust device of this embodiment It is installed at the position of the engine air inlet 3, and is fixed with the inner wall of the engine air inlet 3 by the main body 1. By this, when the outside air enters the engine, it will first pass through the intake and exhaust devices to generate cyclone gas, which can effectively make the engine The air flow is larger and fuller, which makes the fuel burn more completely, significantly increases the engine output power, and ultimately reduces carbon dioxide emissions.

However, the above descriptions are only preferred embodiments of the present utility model, and the patent scope of the present utility model cannot be limited accordingly. Simple modifications and equivalent structural changes can be made by using the description and drawings of the present utility model as examples. All should be similarly included in the patent scope of the present utility model, and are hereby declared.

Therefore, please refer to all the accompanying drawings. When used, the utility model does have the following advantages compared with common technologies:

First, this case is for an engine with an internal combustion engine. When the engine is inhaling, a suction force close to a vacuum will be generated in the cylinder. According to Baidu's law of fluid mechanics, the flow rate is fast and the pressure is low. Therefore, the air outlet 122 of this case is The air pressure is lower than the air pressure at the air inlet 121 end, so it is beneficial for the gas A to be sucked into the cylinder.

Second, when gas A passes through the inlet and exhaust device, the DC flow rate in the middle is faster than the surrounding cyclone gas B, which means that the DC air pressure is lower than the air pressure of cyclone gas B. This allows cyclone gas B to pass through the second When the perforation is 12, it will not spread out, but will rotate more concentratedly.

Thirdly, since cyclone gas B is a rapidly rotating vortex gas, after entering the engine, this type of cyclone gas B will make the engine's air flow larger and fuller, allowing the fuel to burn more completely, significantly increasing the engine's output power and ultimately reducing carbon dioxide emissions.

Fourth, the rapidly rotating cyclone gas B will refine the fuel droplets entering the cylinder, effectively improving combustion efficiency and making exhaust emissions cleaner and more environmentally friendly.

Fifth, users do not need to worry about derivative problems caused by reverse installation during the installation process, achieving a non-directional advantage. Even if it is installed by non-professionals, there will be no problems.

Sixth, when the present invention is installed in the exhaust pipe 2, since the gas A discharged from the exhaust pipe 2 is under positive pressure, the exhaust gas A generates cyclone gas B when passing through the intake and exhaust device, so that the exhaust pipe 2 can generate liquid and reduce noise at the same time.
