1 to 4, the multi-air pump 100 according to an embodiment of the present invention includes a plurality of intake and exhaust units 110, a compression unit 120, and a driver 130.

The plurality of intake and exhaust units 110 are spaced apart from each other and serve to suck or discharge air. The plurality of intake and exhaust units 110 are alternately compressed by the compression unit 120 to suck outside air and discharge the inside of the sealed space. As the outside air is injected into the sealed interior by the compression unit 120, the inside air pressure increases.

Specifically, the plurality of intake and exhaust units 110 include a first intake and exhaust unit 111 and a second intake and exhaust unit 112, and the compression unit 120 to be described later alternately the first intake and exhaust unit 111 and the second intake and exhaust. The unit 112 is compressed. The first intake and exhaust part 111 includes a first intake part 111-1, a first flow path tube 111-2, and a first exhaust part 111-3. Outside air is sucked into the first intake portion 111-1. In this case, due to the difference in air pressure by the compression unit 120, outside air is sucked through the first intake unit 111-1. The first flow pipe 111-2 is a passage through which the outside air sucked in accordance with the air pressure difference moves while the first compression rod 122-1 of the compression unit 120 moves. The first exhaust part 111-3 is connected to the first flow path pipe 111-2 to discharge the outside air sucked in. The space discharged through the first exhaust part 111-3 is preferably sealed.

On the other hand, the second intake and exhaust unit 112 includes a second intake unit 112-1, a second flow path tube 112-2, and a second exhaust unit 112-3. Outside air is sucked into the second intake portion 112-1. In this case, due to the difference in air pressure by the compression unit 120, outside air is sucked through the second intake unit 112-1. The second flow path tube 112-2 is a passage through which the outside air sucked in accordance with the air pressure difference moves while the second compression rod 122-2 of the compression unit 120 moves. The second exhaust part 112-3 is connected to the second flow path tube 112-2 to discharge the outside air sucked in. It is preferable that the space discharged through the second exhaust part 112-3 is sealed.

The compression unit 120 serves to compress air while reciprocating between the plurality of intake and exhaust units 110. The compression unit 120 may sequentially compress the plurality of intake and exhaust units 110 while moving in the horizontal direction. For example, when the compression unit 120 compresses the first intake and exhaust unit 111, external air is sucked in the second intake and exhaust unit 112, and the compression unit 120 compresses the second intake and exhaust unit 112. In this case, outside air is sucked from the first intake and exhaust unit 111.

More specifically, the compression unit 120 includes a connection portion 121 and the pressure plate 122. The connection part 121 is a rod connecting between the plurality of intake and exhaust parts 110. For example, at least one connection part 121 is connected between the first intake vent 111 and the second intake vent 112 in a horizontal direction. In this case, the connecting portion 121 may have a circular or oval cross section, and serves to guide the pressing plate 122 to move horizontally left and right along the connecting portion 121. Accordingly, the pressure plate 122 may be supported so as not to deviate from the path while switching the rotation of the motor 131 of the driving unit 130 to the horizontal motion.

The pressing plate 122 of the compression unit 120 is formed with a first compression rod 122-1 on one side of the body, and a second compression rod 122-2 on the other side. The first compression rod 122-1 is inserted into the first flow path tube 111-2 of the first intake and exhaust unit 111, and the second compression rod 122-2 is moved in the second intake and exhaust unit 112. Is inserted into and moved to the second flow path tube 112-2. In this case, the cross section of the first compression rod 122-1 is formed in a shape corresponding to that of the first flow passage 111-2, and the cross section of the second compression rod 122-2 is the second flow passage. It is preferable that it is formed in the shape corresponding to the cross section of (112-2). A guide groove 122-3 is formed at one side of the body of the pressure plate 122 to move along the connection part 121. In this case, the guide groove 122-3 may be formed correspondingly according to the number of the connection parts 121. An accommodation groove 122-4 is formed in the center of the body of the pressure plate 122, and the output terminal 131-1 of the driving unit 130 is inserted therein.

The drive unit 130 is connected to the compression unit 120, the output end 131-1 for rotational movement serves to horizontally move the compression unit 120. More specifically, the drive unit 130 includes a motor 131, a bracket 132 and a drive wheel 133. The motor 131 may be driven by an AC or DC power source. The driving wheel 133 is inserted into the output end 131-1 of the motor 131 and is formed at a position perpendicular to the receiving groove 122-4 of the pressure plate 122. In other words, the pressure plate 122 and the motor 131 may be connected in a '┴' shape, but is not necessarily limited thereto. The motor 131 may be connected to the pressure plate 122 at various angles by using a gear combination.

The bracket 132 is formed in a shape in which the upper and lower parts are assembled, and serves to fix the motor 131. In addition, the bracket 132 is formed with a heat dissipation groove (not shown) serves to discharge the heat generated from the motor 131 to the outside. This is to prevent the motor 131 from overheating, and a heat radiation groove having a predetermined pattern is formed inside the bracket 132 in contact with the outer surface of the motor 131 to serve to release heat to the outside. have.

The driving wheel 133 is a rotating body inserted into the output terminal 131-1 of the motor 131. The driving wheel 133 may be formed by protruding the pressing protrusion 133-1 on one side in a circular disk shape. As the driving wheel 133 rotates by the motor 131, the pressing protrusion 133-1 also rotates. In this case, the pressing protrusion 133-1 is inserted into the receiving groove 122-4 of the pressing plate 122 to rotate. As the pressing protrusion 133-1 rotates in the inserted state in the receiving groove 122-4, the pressing plate 122 is moved in the horizontal direction by the pressing protrusion 133-1.

Referring to Figure 4, (a) and (b) shows that the pressing plate 122 is moved by the pressing projection 133-1. R1 represents the radius of the width of the receiving groove 122-4, R2 represents the rotation radius of the pressing projection 133-1, R3 represents the horizontal moving distance of the pressing plate 122. In this case, a relationship such as "R3 = R2-R1" is formed. In other words, when the pressing projection 133-1 rotates clockwise, the first compression rod 122-1 moves to the left by R3 when the rotation of the pressing projection 133-1 rotates from the 6 o'clock of (a) to the 9 o'clock of (b). do. Receiving groove 122-4 is formed with inscribed circle 122-41 and circumscribed circle 122-42, the radius of inscribed circle 122-41 is R1, the radius of circumscribed circle 122-42 is R2. . Upper and lower portions of the accommodation grooves 122-4 are in contact with the circumscribed circle 122-42. If you want to lengthen the horizontal movement distance of the pressure plate 122 is set by narrowing the width of the receiving groove (122-4), if you want to shorten the horizontal movement distance is set by widening the width of the receiving groove (122-4) .

5 and 6, the injection apparatus 1000 using the multi air pump according to another embodiment of the present invention includes a case 1100, a multi air pump 1200, and a controller 1300.

The case 1100 is made of synthetic resin or metal, and closes the opened upper portion of the container 2000. In this case, the container 2000 is formed of a synthetic resin material or a metal material, the inside of which is empty and the top of the container 2000 is opened. The spraying material contained in the container 2000 may be a gas or a liquid material. The case 1100 has a nozzle 1110 formed at one side to discharge the spraying material in the container 2000. The handle 1120 may be integrally formed at the other side of the case 1100 or may be coupled by a connection member.

In addition, the case 1100 is formed with a transfer pipe 1130 to the lower side to allow the injection material in the container 2000 to move to the lever 1140. A lever 1140 is formed in the case 1100 to open and close the transfer pipe 1130. For example, when the lever 1140 is in the correct position, the transfer pipe 1130 is closed, and when the lever 1140 is retracted backward, the transfer pipe 1130 is opened. The function of the lever 1140 may be changed to any structure that can open and close the transfer pipe 1130.

The multi-air pump 1200 is formed inside the case 1100, while being spaced apart from each other and located side by side and reciprocating between the plurality of intake and exhaust units 1210 and the plurality of intake and exhaust units 1210 to suck or discharge air. A compression unit 1220 for compressing air and an output end 131-1 for rotating motion are connected to the compression unit 1220 and include a driving unit 1230 for horizontally moving the compression unit 1220. In this case, the plurality of intake and exhaust units 1210, the compression unit 1220, and the driving unit 1230 may include the plurality of intake and exhaust units 110 and the compression unit 120 of the multi-air pump 1200 described with reference to FIGS. 1 to 4. And since it is the same configuration as the drive unit 130, a detailed description thereof will be omitted.

The controller 1300 controls the driving unit according to the air pressure in the container 2000. The controller 1300 is set to turn on or off the power using the switch 1310. The controller 1300 detects the air pressure in the container 2000 by using the air pressure sensor 1320. For example, when the air pressure in the container 2000 is equal to or greater than the preset air pressure, the operation of the motor may be stopped when the current consumption of the motor of the driving unit is a predetermined amount or more. This is to save power by automatically discharging all the spraying material in the container 2000 or stopping the operation of the motor when the user does not operate the lever 1140.

In addition, the controller 1300 controls the driving of the driver by detecting the inclination of the case 1100. The controller 1300 detects the inclination of the case 1100 using the inclination sensor 1330. For example, when the inclination of the case 1100 exceeds a predetermined inclination, the operation of the motor may be stopped. This is determined that the use of the injection device 1000 is abnormal, in order to prevent a safety accident when the injection material is a material that requires handling care in use. This setting may be released by the user.

On the other hand, the injection device 1000 using the multi-air pump according to the present invention may further include a power supply 1400. The power supply 1400 may be formed in an area of the handle 1120 of the case 1100. The power supply unit 1400 may be implemented using a battery. The power supply unit 1400 supplies power to the driving unit 130 and the control unit 1300. The power supply unit 1400 supplies power where power is required in the smart injector 1000. When the remaining power level is less than the preset reference amount, the warning sound may be output through a speaker (not shown).

On the other hand, the injection device 1000 using a multi-air pump according to the present invention may further include an illumination unit (not shown). The lighting unit may be implemented as an LED, and is formed to irradiate light in the direction of the nozzle 1110. The lighting unit may be turned on or off through the switch 1310. The illumination unit may use an illuminance sensor (not shown) to automatically output the light when the surrounding becomes dark. Accordingly, the user may use the smart injection device 1000 even in the dark night.
