Description

Air compressor that supplies high-pressure air

The present invention relates to an air compressor. To be described in more detail, a vertical motion piston is inserted into a cylinder, a horizontal motion piston is inserted into the vertical motion piston, and a vertical motion piston is inserted into the vertical motion piston while omitting the connecting rod. When the crankshaft is inserted and rotated, the vertical motion piston reciprocates in the up and down directions, and the horizontal motion piston reciprocates in the left and right directions, pressurizing and compressing the air twice and then supplying it to the air tank. This relates to an air compressor that can achieve the same effect as compressing air with four pumps and has a simple structure to minimize volume.

In general, an air compressor is a device that allows a compressor operated by an electric motor to suck in external air and continuously supply it to an air tank, thereby filling the inside of the air tank with air at a desired pressure.

The conventional air compressor 1 shown in FIGS. 1 and 2 includes an air tank 11 filled with compressed air, a wheel 11a installed on the lower part of the air tank 11, and a wheel fixed to the upper part of the air tank 11. A mounting plate (12), an electric motor (13) fixed to the upper part of the mounting plate (12) with a bolt (B), and an electric motor (13) installed inside the crank case (14) and rotated by the electric motor (13).

The charge is coupled to the crankshaft 15, a pulley 16 connected to the crankshaft 15, a blowing fan (cooling fan) 17 formed integrally with the pulley 16, and the crankshaft 15. A connecting rod 18, a piston 21 connected to the connecting rod 18 and reciprocating up and down inside the cylinder 19, and a piston 21 formed at the top of the cylinder 19 to suck in compressed air and compressed air. It consists of an intake and exhaust part 22 for discharging.

In the conventional air compressor configured in this way, when the electric motor 13 operates, the driving force is transmitted to the belt 16a wound around the pulleys 13a and 16 to rotate the crankshaft 15, and at this time, the connecting rod 18 The piston 21 connected to reciprocates up and down inside the cylinder 19 to compress the air.

The intake/exhaust unit 22 operates when sucking or discharging air into the cylinder 19 to store compressed air in the air tank 11.

However, the conventional air compressor compresses air by rotating the connecting rod 18 once, so the efficiency of compressing air is low, and there are limitations in compressing air to high pressure, and multiple connecting rings are required to compress air to high pressure. There is a problem that the size increases because a load is required.

Meanwhile, the piston and the crankshaft are located between the connecting rods, and then the upper part of the connecting rod is connected to the piston, and the lower part is eccentrically connected to the crankshaft.

When the piston reciprocates in the up and down direction, the connecting rod is eccentrically connected to the crankshaft to move linearly in the vertical direction, and then descends and rises in a diagonal direction.

Since force is transmitted at approximately 35° based on the vertical line of the connecting rod, only approximately 25% of the energy transmitted through the reciprocating motion of the piston is transmitted, resulting in lower output and lower efficiency.

The reason why the above problem occurs is because linear motion cannot be converted into rotational motion when the piston and crank are directly connected, so by connecting them through a connecting rod and then converting, the energy output generated from the reciprocating motion of the piston is properly transmitted. A problem arises where it cannot be done.

In addition, since the piston and the crank are connected by a connecting rod as in the past, there is a problem in that the volume of the cylinder increases due to the connecting rod, which increases the installation space.

Korean Patent Application No. 10 - 2004 - 0054185 "Design of an ophthalmic air compressor for installing an air compressor in all small, medium and large car models"

As a means to solve the above problem, the air compressor of the present invention inserts a vertical motion piston inside the cylinder and a horizontal motion piston inside the vertical motion piston to sequentially repeat vertical reciprocating motion and horizontal reciprocating motion to compress air to high pressure. Of course, the purpose is to improve the production efficiency of air compressed at high pressure.

In addition, the present invention converts linear motion into rotational motion by directly combining the piston and crank rather than using a connecting rod as in the prior art, so that high-pressure air compressed four times is supplied to the air tank without loss of power energy. They are trying to provide supplies.

As a means of solving the above problem, the present invention provides an upper intake port on the upper surface of a cylindrical cylinder that supplies air from the outside to the upper part of the first piston chamber, and an upper exhaust port that exhausts the pressurized air when the vertical movement piston rises through the upper right intake port. port, on the upper right side, an upper right intake port for supplying air supplied from the upper exhaust port into the second piston chamber, and on the upper left side for exhausting the air compressed by the pressure of the horizontal motion piston to the air tank. An exhaust port, a lower intake port on the bottom of the body that supplies air to the lower part of the first piston chamber from the outside, a lower exhaust port that exhausts pressurized air when the vertical movement piston descends to the lower left intake port, and a lower left side. A cylinder has a lower left intake port that supplies air supplied from the lower exhaust port into the second piston chamber, and a lower right exhaust port on the lower right side to exhaust air compressed by the pressure of the horizontal motion piston into the air tank. , a vertical motion piston is inserted into the first piston chamber formed inside the cylinder, a horizontal motion piston is inserted into the second piston chamber formed inside the vertical motion piston, and then the vertical motion piston and the horizontal motion piston are combined by inserting a crank. Then, the camshaft is attached to the cam of the crank and coupled to protrude out of the cylinder, and when the vertical motion piston descends vertically from the top to the bottom, the horizontal motion piston also descends along with the vertical motion piston and moves horizontally to the right at the same time, Conversely, when the vertical motion piston rises vertically upward, the horizontal motion piston also moves horizontally to the left, providing an air compressor that supplies high-pressure air to reciprocate and compress the air.

As described above, the air compressor of the present invention for supplying high-pressure air includes a vertical motion piston located inside a cylinder, a horizontal motion piston is inserted into the vertical motion piston, and then a crank is inserted and coupled to the connecting rod by rotation of the crank. By converting linear motion into rotary motion, the vertical motion piston reciprocates in the up and down directions, and the horizontal motion piston reciprocates in the left and right directions, pressurizing the air 2 to 4 times to produce high-pressure air. It works.

In addition, the present invention can increase the production of compressed air by sequentially repeating the up-and-down reciprocating motion and the left and right horizontal reciprocating motion by the up-and-down piston and the horizontal motion piston, which is equivalent to using four pumps, and can increase the production of compressed air without a connecting rod. It has the effect of producing compressed air without loss of power energy through reciprocating motion that converts linear motion into rotational motion.

The present invention has the effect of minimizing the volume of the air compressor because the horizontal motion piston is inserted into the vertical motion piston inside the cylinder and does not require a connecting rod.
