Conventional injection devices are widely used for fire extinguishing and spraying. The injection device can be used for various purposes such as cleaning with high pressure, spraying of pesticide, and fire suppression. The conventional injection apparatus has a limitation on the amount and speed of the jetted liquid discharged by pumping the jetted liquid using one jetting pump. In addition, the conventional injection device has pumped due to a difference in air pressure caused by a user manually moving the lever, and thereafter, a technique of spraying using a DC power source has been developed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The terms used are terms selected in consideration of the functions in the embodiments, and the meaning of the terms may vary depending on the user, the intention or the precedent of the operator, and the like. Therefore, the meaning of the terms used in the following embodiments is defined according to the definition when specifically defined in this specification, and unless otherwise defined, it should be interpreted in a sense generally recognized by those skilled in the art.

FIG. 1 is a configuration diagram of a smart injection device using a plurality of air pumps according to an embodiment of the present invention, and FIG. 2 is a detailed configuration diagram of the smart injection device according to FIG.

1 and 2, a smart injection apparatus 100 using a plurality of air pumps according to an embodiment of the present invention includes a body 110, a compression unit 120, a driving unit 130, and a controller 140 ).

The body portion 110 is made of a synthetic resin material or a metal material, and closes the open upper portion of the container 10. In this case, the container 10 is made of a synthetic resin material or a metal material, and is formed in such a form that the inside is empty and the top is opened. The jetting material contained in the vessel 10 may be a gas or liquid material. A nozzle 111 is formed on one side of the body 110 to discharge the jetting material in the container 10. On the other side of the body portion 110, a handle 112 may be integrally formed or may be coupled by a connecting member.

A flow pipe 113 is formed on the lower side of the body 110 so that the injected material in the container 10 can be moved to the lever 114. A lever 114 is formed on the body 110 to open and close the flow pipe 113. For example, when the lever 114 is in the correct position, the flow pipe 113 is closed, and when the lever 114 is moved backward, the flow pipe 113 is opened. The function of the lever 114 may be changed to any structure capable of opening and closing the flow pipe 113. A plurality of through holes (not shown) are formed on the lower side of the body 110, and the through holes are connected to the compression unit 120 to be described later so that external air can be injected into the container 10.

The compression unit 120 is formed inside the body 110 to discharge the sucked air into the container 10 while alternately compressing the plurality of air pumps. For example, the compression unit 120 is formed so that two air pumps are spaced apart from each other. The compression unit 120 alternately compresses the compressed air by a driving unit 130, which will be described later, and sucks outside air and discharges the compressed air into the container 10. As the external air is injected into the container 10 by the compression unit 120, the air pressure inside the container 10 increases. In this case, the jetting material inside the vessel 10 is discharged to the outside along the flow pipe 113. A specific configuration of the compression unit 120 will be described later with reference to FIG. 3 and FIG.

The driving unit 130 alternately compresses the plurality of air pumps by the rotation of the motor, and discharges the jetting material stored in the container 10 to the outside through the nozzle 111. In this case, the motor can be located between the plurality of air pumps. The driving unit 130 may be driven by an internal or external power source. The driving unit 130 can determine the rotational speed and operation of the motor according to the air pressure inside the container 10 or the inclination of the container 10 by the control unit 140 described later. A detailed description of the driving unit 130 will be given later with reference to FIG.

The control unit 140 controls the driving of the motor in accordance with the air pressure in the container 10. The control unit 140 is set to turn on or off the power using the switch 141. [ The control unit 140 senses the air pressure in the container 10 by using the air pressure sensor 142. For example, when the air pressure in the vessel 10 is equal to or higher than the preset air pressure, the operation of the motor can be stopped if the consumption current of the motor is equal to or greater than a predetermined amount. This is for discharging all of the injected material in the vessel 10 so that there is no injection material to be discharged, or when the user does not operate the lever 114, the operation of the motor is automatically stopped to conserve power.

In addition, the controller 140 senses the inclination of the body 110 and controls driving of the motor. The controller 140 senses the tilt of the body 110 using the tilt sensor 143. For example, when the inclination of the body 110 exceeds a predetermined inclination, the operation of the motor can be stopped. This is because it is determined that the use of the injecting apparatus 100 is abnormal, and in order to prevent a safety accident when the injecting substance is a substance requiring handling attention in use. This setting may be released by the user.

Meanwhile, the smart injection apparatus 100 using a plurality of air pumps according to the present invention may further include a power supply unit 150. The power supply unit 150 may be formed in the region of the handle 112 of the body 110. The power supply unit 150 may be implemented using a battery. The power supply unit 150 supplies power to the driving unit 130 and the control unit 140. The power supply unit 150 supplies power to the smart injection apparatus 100 in a place where power is required. And may output a warning sound through a speaker (not shown) when the remaining power level is less than the preset reference level.

Meanwhile, the smart injection apparatus 100 using a plurality of air pumps according to the present invention may further include an illumination unit (not shown). The illumination unit may be implemented by an LED, and may be formed to be capable of irradiating illumination toward the nozzle 111. The illumination unit can be turned on and off via the switch 141. [ It is also possible to use an illuminance sensor (not shown) to automatically output illumination when the surroundings become dark. Accordingly, the user can use the smart injection apparatus 100 even in the dark night.

FIG. 3 and FIG. 4 are diagrams for explaining the coupling relationship of the compression unit and the driving unit among the smart injection apparatuses according to FIG.

Referring to FIGS. 3 and 4, the compression unit 120 of the smart injection apparatus 100 according to FIG. 1 includes a first air pump 121 and a second air pump 122. The first air pump 121 is located at one side of the motor 131. The first air pump 121 sucks the outside air through the first suction hole 121-1 and passes through the first discharge hole 121-2 Air is exhausted. The second air pump 122 is located on the other side of the motor 131 and is alternately compressed with the first air pump 121 to suck outside air through the second suction hole 122-1, And air is discharged into the container through the discharge hole 122-2. In other words, the first air pump 121 and the second air pump 122 inject external air into the container through repeatedly compressing alternately by the motor 131.

For example, when the first air pump 121 is compressed, the air stored in the first air pump 121 is discharged to the inside of the container, and the second air pump 122 is expanded to suck the outside air, And stored in the air pump 122. Thereafter, when the second air pump 122 is compressed, the air stored in the second air pump 122 is discharged to the inside of the container. The first air pump 121 expands and sucks the outside air, (121). Accordingly, as the motor 131 rotates once, the first air pump 121 and the second air pump 122 are compressed and expanded once, and a total of two air infusions are performed in the container.

5 is an exploded perspective view of the driving part of the smart injection device according to FIG.

Referring to FIG. 5, a driving unit 130 of the smart injection apparatus 100 according to FIG. 1 includes a motor 131, a driving wheel 132, and a pressure plate 133.

The motor 131 is driven by an internal or external power source. In this case, the motor 131 uses a DC power source, but is not limited thereto. The motor 131 outputs rotational power through the drive shaft 131-1. The drive shaft 131-1 of the motor 131 can rotate in the forward direction or the reverse direction. The motor 131 drives the drive wheel 132 to be described later. When the motor 131 rotates once, the plurality of air pumps alternately compress and expand, and the air is sucked and discharged once each time. A speed reducer (not shown) may be provided on the driving shaft 131-1 of the motor 131 to adjust the driving speed of the motor 131. [

The driving wheel 132 is connected to the driving shaft 131-1 of the motor 131 and the pressing projection 132-1 is formed on the surface thereof. The drive wheel 132 is a medium for converting the rotational motion of the motor 131 into a reciprocating motion. The driving wheel 132 is formed in a circular shape and a pressing protrusion 132-1 is formed on one side of the circumferential surface. The press protrusion 132-1 is installed to be inserted into the engaging groove 133-1 of the pressure plate 133, which will be described later. A bearing (not shown) may be inserted into the drive wheel 132 to reduce friction with the drive shaft 131-1 of the motor 131. [

The pressure plate 133 is formed between the air pumps and serves to compress a plurality of air pumps while moving left and right. The pressure plate 133 has a rectangular engaging groove 133-1 formed on one surface thereof. The latching groove 133-1 is formed in the longitudinal direction, and the pressing projection 132-1 of the driving wheel 132 is inserted. For example, when the motor 131 rotates, the pressing projection 132-1 is engaged with the engaging groove 133-1 of the pressing plate 133 while rotating, so that the pressing plate 133 reciprocates in the horizontal direction, The pump is alternately pressurized. In this case, it is preferable that the pressure plate 133 is fixed so as not to move in the vertical direction within the body portion, and is formed so as to be reciprocated in the left and right horizontal directions.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, Therefore, the present invention should be construed as a description of the claims which are intended to cover obvious variations that can be derived from the described embodiments.
