Description

Technology Field

[0001] The present invention relates to a compressor device with improved usability that can improve user accessibility and work efficiency in various work environments. Background Technology

[0003] Compressor units play the role of generating compressed air and supplying it to various tools and equipment, and are essential in a very wide range of industrial fields, including automotive repair, metalworking, woodworking, electronics manufacturing, construction sites, and cleaning and maintenance operations. In typical work environments, compressed air is used to remove metal powder or dust through high-speed jets or to drive pneumatic tools, and is further utilized in various auxiliary processes such as painting, cooling, and cleaning. As such, compressor units have established themselves not merely as auxiliary equipment, but as foundational equipment directly linked to productivity.

[0004] Conventional compressor units typically feature a structure where the compressor is housed inside the main body, with an air gun or spray tool connected externally. Users store the air gun on a stand attached to the side of the main body or organize the cable using a cable winding device if available. However, most of these conventional devices focus solely on the basic compressed air supply function and have failed to effectively address the inconveniences experienced by workers in the field. For instance, if the equipment is located far from the work site, users must pull out long cables, and the cables scattered on the floor frequently cause tripping hazards or damage. Furthermore, when the air gun is simply resting on the side of the main body, instability occurs during the attachment and detachment process, and even when stored, the nozzles may be misaligned, making maintenance difficult.

[0005] To address this, some prior art has proposed methods such as attaching a cable winding device to the side of the main body or improving a simple stand to secure the air gun using magnets or clips. Additionally, devices have been reported that allow multiple spray tools to be connected to the main body, considering multi-person work environments. However, these prior technologies still failed to resolve the inconvenience of the user having to manually pull and retract the cable, nor did they provide a function for the air gun to automatically deploy according to the user's position. Consequently, conventional technologies have limitations as they were limited to only partial improvements for enhancing convenience.

[0006] The problems with the prior art can be broadly summarized into four points. First, there is the issue of mismatch between the worker's movement path and the device placement. Since the main unit is fixed in a specific location within the workspace while the worker moves around to perform tasks, users must endure the inconvenience of repeatedly bending over or organizing cables unless the air gun deploys automatically. Second, there is the issue of cable management. If cables are left on the floor, not only does the risk of tangling and breakage increase, but it can also lead to safety accidents where other workers trip over them. Third, there are limitations in multi-person work environments. When two or more workers attempt to work simultaneously, the air gun cables interfere with or become tangled, reducing usage efficiency and workspace utilization. Fourth, there is a lack of diversity in operating modes. Conventional devices are only capable of simple spraying; therefore, separate equipment must be used for specialized tasks such as floor cleaning, which leads to increased costs and equipment management burdens.

[0007] These issues are inconveniences that field workers have consistently pointed out. To improve work efficiency, features are required where the air gun automatically extends toward the operator's reach, automatically returns to its original position after use, and the cable is neatly organized. Additionally, interference must be minimized even when two or more workers use the device simultaneously, and a structure is required that allows the air gun to be rotated at a specific angle to easily switch to special modes, such as floor cleaning. Furthermore, since these features go beyond merely providing additional convenience and are directly linked to work safety, equipment durability, and the reduction of worker fatigue, there is a growing demand in the industry for new types of compressor devices that can overcome the limitations of existing equipment. Prior art literature

[0009] Republic of Korea Published Patent Application No. 2014-0133020 Republic of Korea Registered Patent Application No. 0994904 Republic of Korea Registered Patent Application No. 1487240 Republic of Korea Registered Patent Application No. 1263906 The problem to be solved

[0010] The objective of the present invention is to overcome the limitations of existing compressor devices used at work sites and to improve the convenience and efficiency of workers. Specifically, the present invention aims to solve the following problems.

[0011] First, conventional compressor devices often have the problem that the air gun is simply mounted near the main body or connected only by a cable, making it difficult for the operator to use it freely at a certain distance from the main body. Therefore, the present invention aims to improve the accessibility and convenience of the operator by providing a rotating arm module that allows the high-pressure spraying means to be actively deployed according to the operator's position.

[0012] Second, the winding method of existing air guns is often a simple reel type, which causes problems such as the cable not being organized or becoming tangled after use. The present invention aims to improve the organization efficiency and safety of the workspace by combining a spring-return type cable winding means and a magnetic mounting detection sensor so that when the air gun is remounted, the cable is automatically organized and the rotating arm returns to the main body.

[0013] Third, conventional technology had limitations in supporting multiple operators to use an air gun simultaneously or various work modes (e.g., floor cleaning, dual operation, etc.). Another objective of the present invention is to enable adaptation to various work environments by providing a rotating arm module with a left-right symmetrical structure and defining single mode, dual mode, and floor cleaning mode through a control unit.

[0014] Fourth, in existing devices, it is difficult to intuitively check the remaining amount of compressed air, so there have been cases where the operator experienced inconvenience due to a shortage of compressed air during use. The present invention aims to synchronize the number display on the front of the main body with the gauge display at the end of the rotating arm so that the operator can immediately check the remaining amount of compressed air not only near the device but also from a distance.

[0015] Therefore, the main objective of the present invention is to comprehensively improve user convenience, space utilization efficiency, multi-mode support, safety, and intuitive information provision. means of solving the problem

[0017] A compressor device with improved ease of use according to the present invention may include a main body module for generating compressed air, a bracket coupled to the side of the main body module and functioning as a hinge point, a pivoting arm module hinge-coupled to the bracket and supported so as to be rotatable, a mounting portion formed at the end of the pivoting arm module for mounting a high-pressure spraying means, and an output control means for switching the intensity of compressed air supplied to the high-pressure spraying means coupled to the mounting portion. The pivoting arm module is characterized by being formed so that the high-pressure spraying means extends in a direction within reach of the operator's hand while the operator's working position and the main body module are fixed to each other.

[0018] Next, the main body module may include a compressor unit disposed internally, a connection port formed on the front to connect the compressor unit to the outside, wheels supported on the bottom surface to enable movement in the workspace, and a fastening area provided on the side outer wall to fasten the bracket. The bracket may be fixed to the fastening area of ​​the main body module. The bracket may include a pair of support plates spaced apart parallel to each other outwardly, and a cylindrical pin disposed across the support plates. The cylindrical pin may function as a pivot axis. The pivot arm module may be rotatably supported on the bracket by the pivot axis. The pivot arm module may include an outer arm body, an inner arm body slidably coupled to the outer arm body in the longitudinal direction, and a lead screw disposed inside the outer arm body. The lead screw may be coupled to a small motor. As the inner arm body moves back and forth in conjunction with the rotation of the motor, the length of the pivot arm module may be electrically adjusted. The pivoting arm module can receive an operation signal through electrical wiring connected to the main body module. The pivoting arm module may further include a rotational driving means for rotating around the pivot axis. The rotational driving means may include a motor coupled to a hinge portion of the pivoting arm module and a reduction gear portion that converts the rotation of the motor into rotation around the pivot axis. The deployment of the pivoting arm module may be initiated by a deployment trigger including a pedal stepped on by an operator. The pedal may be electrically connected to the motor through the electrical wiring. When the operator steps on the pedal, the pivoting arm module may rotate and deploy in the direction of the operator around the pivot axis.After the above rotational deployment reaches a predetermined deployment point, a distance sensing sensor positioned at the end of the rotational arm module measures the distance to the operator, and according to the measured distance value, drives the motor to advance or retract the inner arm body, and as a result, the inner arm body moves by the corresponding distance, thereby allowing the length of the rotational arm module to be adjusted to a position within reach of the operator's hand. The high-pressure spraying means may include an air gun body held by hand and a high-pressure cable connected to the air gun body. The mounting member may include a U-shaped mounting groove coupled to the end of the pivoting arm module to allow the air gun body to rest thereon, an elastic pad disposed on the contact surface of the mounting groove, a tapered guide formed at the entrance of the mounting groove to facilitate quick insertion and removal of the air gun body, a magnetic adsorption part provided in the mounting groove and the tapered guide to magnetically fix the air gun body, a cable mounting clip provided on one side of the pivoting arm module to grip the high-voltage cable and prevent detachment, and a spring-return type cable winding means for winding and unwinding the high-voltage cable by elastic force. The high-voltage cable is wound by the cable winding means, and may be guided so that winding is performed while mounted on the cable mounting clip. The mounting member, the air gun body, and the high-voltage cable may move together according to the rotation and length adjustment of the pivoting arm module. When an operator detaches the air gun body from the mounting member, the cable winding means may allow unwinding. The air gun body may be re-mounted on the mounting part after use, and the high-voltage cable may be automatically returned by the elastic force of the cable winding means.When the air gun body is re-mounted on the mounting part by the magnetic adsorption part, a magnetic mounting detection sensor positioned near the mounting part detects this and generates a signal, and according to the signal, the motor is driven in reverse so that the rotating arm module can automatically return to the direction of the body. At the same time, the high-voltage cable is mechanically automatically returned by the elastic force of the cable winding means.

[0019] Next, the main body module may further include a pair of fastening areas formed to face each other on the left and right sides. The bracket may be fixed to the left fastening area and the right fastening area, respectively. Each bracket may include a support plate spaced outwardly parallel and a cylindrical pin disposed across between the support plates. The cylindrical pin may function as a pivot axis for the left and right sides. The pivot arm module may be hinge-coupled to the left bracket and the right bracket, respectively, to be rotatably supported. The left pivot arm module may be deployed to the left relative to the main body module. The right pivot arm module may be arranged to be deployed to the right relative to the main body module. The left pivot arm module and the right pivot arm module may be configured to rotate in opposite directions. The mounting portion is formed at the ends of the left pivot arm module and the right pivot arm module, respectively, so that an air gun main body can be mounted on each mounting portion. A spring-returning cable winding means and a high-voltage cable may be provided to be independent of each other on the left and right sides. The above high-voltage cable can be guided along a dedicated path to prevent interference between the left and right sides. Two air guns can be connected to the main body module simultaneously. The left air gun and the right air gun can be positioned so that two spaced-apart workers can simultaneously grip and use them. The left pivot arm module and the right pivot arm module are characterized by having a pivot limit of 135 degrees defined by a stopper that limits over-pivoting throughout the designed pivot range.

[0020] Next, the magnetic adsorption part is intended to repeatedly fix the nozzle direction of the air gun body to a reference position and may include a plurality of magnets symmetrically arranged on the inner side of the mounting groove and the tapered guide part, respectively, and an iron piece inserted and fixed to the outer circumference of the air gun body. Depending on the arrangement direction of the magnets and the iron piece, the nozzle may be guided to face the same set reference direction when the air gun body is mounted. The mounting part may further include a rotation unit for changing the nozzle direction while the air gun body is mounted aligned in the reference direction. The rotation unit may further include a rotation seat made of a support disc that rotates the mounting part from the rotation arm module, a plurality of shallow grooves provided on the outer circumference of the rotation seat to form a concave spot for position fixation, a spherical catch piece disposed in a spring receiving hole formed around the entrance of the mounting groove and selectively caught in the shallow groove by the elastic force of the spring, and an angle index detection switch that electrically detects whether the rotation seat has reached a specific angle such as the floor cleaning direction and provides a signal to the control unit. The above-mentioned catch is configured in the shape of a metal bead and can function to fix the position when the rotating seat reaches a specific angle. The rotating seat can be rotatably positioned so that the nozzle is switched in an inclined direction toward the floor surface. The angle can be index-fixed in the inclined direction by the spherical catch engaging with the shallow groove. The main body module may be equipped with a control unit for selecting and switching the operation of the rotating arm module and the air gun. The control unit may define a single mode that controls the operation of only one air gun, a dual mode that controls the operation of the left and right air guns simultaneously, and a floor cleaning mode that controls the operation of both air guns simultaneously while they are fixed at an index position in an inclined direction toward the floor surface by the rotating seat based on the signal of the angle index detection switch.The control unit can control the operation of only the air gun on the selected side in the single mode. In the dual mode, it can control the operation of the left and right air guns simultaneously. In the floor cleaning mode, the control unit is characterized by controlling the operation of the air gun while it is fixed in the inclined direction.

[0021] Next, the output control means may include an output control switch for switching the spray pressure in stages from 0 to 3 on each air gun body of the high-pressure spraying means. The control unit may automatically determine an operating mode by receiving signals from magnetic mounting detection sensors provided in the left mounting part and the right mounting part, respectively, and an angle index status signal of the rotation unit. The control unit may define a dual mode when the detection count of the magnetic mounting detection sensor is 0. In the dual mode, the left and right air guns operate simultaneously, but can be controlled in conjunction with an output limit interlock means so that the sum of the output stages of the two air guns is 3 or less. The control unit may define a single mode when the detection count of the magnetic mounting detection sensor is 1. In the single mode, only the air gun on the unmounted side can be controlled to operate from 1 to 3. The air gun on the mounted side can be controlled to remain at 0. The control unit may define a floor cleaning mode in which the detection count of the magnetic mounting detection sensor is 2 and the rotating unit is fixed at an index position in an inclined direction facing the floor surface on both sides. In the floor cleaning mode, the air guns on both sides can be controlled to operate simultaneously at a 3-stage output. The main body module may further be equipped with a remaining amount display means for visually displaying the amount of remaining compressed air. The remaining amount display means may be configured so that an operator can check it both near the main body and at the end of the rotating arm. The remaining amount display means may include a numerical display unit on the front of the main body module that displays the amount of remaining compressed air numerically, and an arm end display unit at the end of each rotating arm module that intuitively displays the amount of remaining compressed air as a bar-shaped gauge. The numerical display unit and the arm end display unit are characterized by being coupled to be electrically synchronized based on a common pressure / remaining amount sensor signal. Effects of the invention

[0023] According to the present invention, the following effects can be obtained.

[0024] First, through a pivot arm module rotatably coupled to the main body module and a structure that allows the length of the pivot arm to be electrically adjusted, the high-pressure spraying means can be actively deployed according to the user's position or working radius. Accordingly, the air gun can be easily used at any location desired by the operator regardless of the installation location of the compressor device, thereby greatly improving ease of use.

[0025] Second, the mounting portion provided at the end of the pivoting arm allows the air gun body to be mounted quickly and stably using a tapered guide portion and a magnetic suction portion, and is linked with a spring-returning cable winding means so that the cable is automatically organized as soon as the air gun is mounted again. This configuration not only significantly reduces the time and hassle of cleanup after work is finished, but also contributes to ensuring orderliness and safety at the site.

[0026] Third, through the configuration of a control unit that automatically switches operating modes based on signals from a magnetic mounting detection sensor and an angle index detection switch, a single device can flexibly switch between single mode, dual mode, and floor cleaning mode depending on the situation. As a result, users can immediately utilize operating modes suited to their purpose and situation without changing settings, thereby improving work efficiency.

[0027] Fourth, independent pivot arm modules and air guns are provided on the left and right sides, allowing two operators to share the compressor unit simultaneously. In particular, in dual mode, the two air guns operate simultaneously, but the total output is controlled through an output limiting interlock means, thereby ensuring system stability and pressure distribution efficiency.

[0028] Fifth, by equipping a numeric display on the front of the main body and an arm end display on the end of the rotating arm, the remaining compressed air is intuitively visualized, allowing the user to immediately check the remaining amount of air regardless of their position. This prevents interruptions caused by a lack of compressed air during operation and enhances the efficiency of tool management.

[0029] In conclusion, the present invention effectively overcomes the functional limitations and inconvenience of use of existing compressor devices through mechanical design improvements centered on user convenience, and enables stable and efficient operation in various work environments, thereby providing the effect of significantly enhancing practicality and competitiveness in industrial sites.

[0047] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0048] FIG. 1 is a conceptual diagram of a compressor device with improved ease of use according to the present invention.

[0049] Figure 2 shows a mounting part mounted on the pivot arm module of Figure 1.

[0050] Figure 3 shows a cross-section of the mounting portion of Figure 2.

[0051] Figure 4 shows the main body module of Figure 1 viewed from above.

[0052] Figure 5 shows a control unit and a mode switching block diagram.

[0054] A compressor device with improved ease of use according to the present invention may include a main body module (100) for generating compressed air, a bracket (200) coupled to the side of the main body module (100) and functioning as a hinge point, a pivoting arm module (300) hinge-coupled to the bracket (200) and supported so as to be rotatable, a mounting part (500) formed at the end of the pivoting arm module (300) for mounting a high-pressure injection means (400), and an output control means (600) for switching the intensity of compressed air supplied to the high-pressure injection means (400) coupled to the mounting part (500).

[0055] The above-described pivoting arm module (300) is characterized by being formed such that, while the worker's working position (700) and the main body module (100) are fixed to each other, the high-pressure spraying means (400) is deployed in the direction that the worker's hand touches.

[0057] Next, the main body module (100) may include a compressor unit disposed inside, a connection port formed on the front to connect the compressor unit to the outside, wheels supported on the bottom surface to enable movement in the workspace, and a fastening area provided on the side outer wall to fasten the bracket (200).

[0058] The bracket (200) can be fixed to the fastening area of ​​the main body module (100).

[0059] The bracket (200) may include a pair of support plates spaced apart from each other in parallel to the outside, and a cylindrical pin (210) positioned across the support plates.

[0060] The above cylindrical pin (210) can function as a pivot axis.

[0061] The above pivot arm module (300) can be rotatably supported on the bracket (200) by the above pivot axis.

[0062] The above-described pivoting arm module (300) may include an outer arm (311), an inner arm (312) that is slidably coupled to the outer arm (311) in the longitudinal direction, and a lead screw (313) disposed inside the outer arm (311).

[0063] The lead screw (313) can be coupled to a small motor. As the inner arm (312) moves back and forth in conjunction with the rotation of the motor, the length of the pivoting arm module (300) can be electrically adjusted.

[0064] The above-mentioned pivoting arm module (300) can receive an operation signal through electrical wiring connected to the above-mentioned main body module (100).

[0065] The above-mentioned pivoting arm module (300) may further include a pivoting driving means for pivoting around the pivot axis.

[0066] The above rotational driving means may include a motor coupled to the hinge portion of the rotational arm module (300) and a reduction gear portion that converts the rotation of the motor into rotation around the rotational axis.

[0067] The deployment of the above-mentioned pivoting arm module (300) can be initiated by a deployment trigger including a pedal stepped on by an operator.

[0068] The above pedal can be electrically connected to the motor through the above electrical wiring.

[0069] When the operator steps on the pedal, the pivot arm module (300) can be rotated and unfolded in the direction of the operator around the pivot axis.

[0070] After the above rotational deployment reaches a predetermined deployment point, a distance sensing sensor (314) positioned at the end of the rotational arm module (300) measures the distance to the operator, and according to the measured distance value, the motor is driven to advance or retract the inner arm body (312), and as a result, the inner arm body (312) moves by the corresponding distance, thereby allowing the length of the rotational arm module (300) to be adjusted to a position within reach of the operator's hand.

[0071] The high-pressure spraying means (400) may include an air gun body that is held by hand and a high-pressure cable connected to the air gun body.

[0072] The mounting member (500) may include a U-shaped mounting groove (510) that is coupled to the end of the rotating arm module (300) and allows the air gun body to sit down, an elastic pad disposed on the contact surface of the mounting groove (510), a tapered guide member (512) formed at the entrance of the mounting groove (510) to make it easy to quickly insert and remove the air gun body, a magnetic adsorption member provided in the mounting groove (510) and the tapered guide member (512) for magnetically fixing the air gun body, a cable mounting clip (520) provided on one side of the rotating arm module (300) to grip the high-voltage cable and prevent detachment, and a spring-returning cable winding means (530) for winding and unwinding the high-voltage cable by elastic force.

[0073] The above high-voltage cable is wound by the cable winding means (530), and may be guided to be wound while mounted on the cable mounting clip (520).

[0074] Depending on the rotation and length adjustment of the above-mentioned rotating arm module (300), the mounting part (500), the air gun body, and the high-pressure cable can be moved together.

[0075] When the operator detaches the air gun body from the mounting part (500), the cable winding means (530) can allow unwinding.

[0076] After use, the air gun body is re-mounted on the mounting part (500), and the high-voltage cable is automatically returned by the elastic force of the cable winding means (530).

[0077] When the air gun body is re-mounted on the mounting part (500) by the magnetic adsorption part, a magnetic mounting detection sensor (540) placed near the mounting part (500) detects this and generates a signal, and according to the signal, the motor is driven in reverse so that the rotating arm module (300) can automatically return to the direction of the main body. At the same time, the high-voltage cable is mechanically automatically returned by the elastic force of the cable winding means (530).

[0078] A compressor device with improved ease of use according to one embodiment of the present invention comprises a main body module (100), a bracket (200), a rotating arm module (300), a mounting part (500), a high-pressure injection means (400), an output control means (600), and various components that assist the above.

[0079] The main body module (100) consists of a rectangular housing with an electric or engine-type compressor unit built inside. A connection port made of metal or rubber is provided on the front of the housing to allow for the attachment and detachment of a high-voltage cable, and four wheels are attached to the bottom to facilitate movement. An area is provided on the side for a bracket (200) to be attached, and a plurality of screw grooves for bolt fastening are machined in this area.

[0080] The bracket (200) is fixed to the side of the main body module (100) and consists of a pair of support plates protruding parallel to each other in the left and right directions and a cylindrical pin (210) positioned across them. The cylindrical pin (210) acts as a pivot axis, allowing the pivot arm module (300) to move around this axis. The support plates are formed from iron or aluminum alloy with a thickness of approximately 4 mm, and the cylindrical pin (210) is made of a steel rod with a polished surface.

[0081] The pivoting arm module (300) is hinged to the cylindrical pin (210) of the bracket (200) and supported so as to be pivotable. The pivoting arm module (300) consists of an outer arm (311) and an inner arm (312) that is movable in the longitudinal direction within the outer arm (311). The inner arm (312) is formed in the shape of a square pipe and is coupled to a lead screw (313) disposed inside the outer arm (311). The lead screw (313) is connected to a small motor, and as the motor rotates, the inner arm (312) moves forward or backward, thereby electrically adjusting the length of the pivoting arm module (300). In this process, a reduction gear acts together to enable precise control.

[0082] The pivoting arm module (300) receives an operation signal through electrical wiring extended from the main body module (100). Additionally, a separate pivoting drive means is provided to pivot the pivoting arm module (300), which consists of a rotary motor coupled to a hinge part and a reduction gear part that converts the rotation of the motor into rotation around a pivot axis. A pedal switch stepped on by the user acts as an deployment trigger, and when the pedal is pressed, the pivoting drive means is activated so that the pivoting arm module (300) deploys toward the user.

[0083] When the rotational extension proceeds beyond a certain angle, a distance sensing sensor (314) mounted on the end of the rotational arm module (300) measures the distance to the operator. The value measured by the sensor is transmitted to the control unit (110), so that the inner arm body (312) automatically moves forward or backward so that the air gun is accurately positioned at the height of the user's hand. This distance sensing can be implemented using an infrared method or an ultrasonic method.

[0084] The mounting portion (500) is coupled to the end of the pivoting arm module (300) and is configured to include a U-shaped mounting groove (510) so that the air gun body can naturally settle down. An elastic pad made of rubber or EVA material is attached to the contact surface of the mounting groove (510) to cushion the impact, and a tapered guide portion (512) that gradually narrows is formed at the entrance of the mounting groove (510) to facilitate the insertion and removal of the air gun. In addition, a plurality of magnets are arranged inside the mounting portion (500) and are fixed by magnetic force by combining with an iron piece attached to the outer circumference of the air gun.

[0085] The high-pressure spraying means (400) is composed of a general trigger-type air gun, and the main body is equipped with an output control switch that can switch the spraying pressure from 0 to 3 levels. The air gun main body is connected to a high-pressure cable, and the high-pressure cable is automatically wound by a spring-return type winding means. This winding means is linked with a cable mounting clip (520) provided on one side of a rotating arm, so that the cable does not sag and drag on the floor or get tangled.

[0086] When the operator inserts the air gun back into the mounting groove (510) after using it, it is automatically fixed by the combination of the magnet and the iron piece. At the same time, a magnetic mounting detection sensor (540) installed in the mounting unit (500) detects this and transmits a signal to the control unit (110). The control unit (110) drives the rotating arm module (300) in the reverse direction to return it to its original position, and in this process, the cable winding means (530) operates so that the high-voltage cable is also automatically returned.

[0087] In this embodiment, all components are embodied in a structure that can be actually manufactured, and the air gun is automatically adjusted to the working position (700) so that the user can easily use it, and returns to its original position after use, providing both storage convenience and safety.

[0089] Next, the main body module (100) may further include a pair of fastening areas formed to face each other on the left and right sides.

[0090] The above bracket (200) can be fixed to the left fastening area and the right fastening area, respectively.

[0091] Each bracket (200) may include a support plate spaced outwardly parallel and a cylindrical pin (210) positioned across the support plate.

[0092] The above cylindrical pin (210) can function as a pivot axis on the left and right sides.

[0093] The above-mentioned pivoting arm module (300) can be pivotably supported by being hinge-connected to the left bracket (200) and the right bracket (200), respectively.

[0094] The left pivoting arm module (300) can be deployed to the left side relative to the main body module (100).

[0095] The right pivoting arm module (300) can be positioned to unfold to the right relative to the main body module (100).

[0096] The above left pivot arm module (300) and right pivot arm module (300) can be configured to pivot in opposite directions to each other.

[0097] The above mounting portion (500) is formed at the ends of the left pivoting arm module (300) and the right pivoting arm module (300), respectively, so that an air gun body can be mounted on each mounting portion (500). A spring-returning cable winding means (530) and a high-voltage cable can be arranged to be independent of each other on the left and right sides.

[0098] The above high-voltage cables can be guided along a dedicated path so that the left and right cables do not interfere with each other.

[0099] Two air guns can be simultaneously connected to the main body module (100).

[0100] The left air gun and the right air gun can be positioned so that two spaced-apart workers can simultaneously grip and use them.

[0101] The above left pivot arm module (300) and right pivot arm module (300) are characterized by having a pivot limit of 135 degrees defined by a stopper that limits over-pivoting across the entire designed pivot range.

[0102] A compressor device with improved ease of use according to another embodiment of the present invention includes fastening areas provided to face each other on the left and right sides of the main body module (100). The fastening areas are formed by reinforcing plates integrally formed on the outer wall of the main body and are made of steel plates with a thickness of 5 mm or more so that the brackets (200) on the left and right sides can be stably fixed. Each fastening area has a plurality of screw holes for inserting bolts so that the brackets (200) are securely fastened.

[0103] The bracket (200) is installed independently on the left and right sides, respectively, and each bracket (200) consists of two support plates spaced apart in parallel. The support plates are made of steel or aluminum alloy and are formed to protrude outward by about 80 mm. A cylindrical pin (210) with a diameter of about 15 mm is placed across the support plates, and this cylindrical pin (210) functions as a pivot axis. The cylindrical pin (210) is made of a steel rod with a hardened surface so that wear is minimized even with repeated rotation.

[0104] The pivot arm module (300) is hinged to the left and right brackets (200) respectively and is supported so as to be pivotable. The left pivot arm module (300) is deployed to the left direction relative to the main body module (100), and the right pivot arm module (300) is deployed to the right direction, so they are arranged in a symmetrical structure. Each of the two pivot arm modules (300) is equipped with an independent motor and lead screw (313) drive unit so that they do not interfere with each other, and either one or both can be deployed simultaneously as needed by the user.

[0105] A mounting portion (500) is formed at the end of each pivoting arm module (300), and an air gun body is mounted on each mounting portion (500). The left and right mounting portions (500) have the same structure, and each mounting portion (500) is provided with an independent spring-returning cable winding means (530) and a high-voltage cable. As a result, the left air gun and the right air gun can independently wind and unwind without interference with each other.

[0106] The high-voltage cables are guided along dedicated paths inside the main body module (100). The left cable is placed along a dedicated channel passing through the lower left side of the main body module (100), and the right cable is placed along the lower right side. Due to this dedicated path design, the two cables do not cross or get tangled, and there is no interference even when the operator uses the air gun at the same time.

[0107] The left air gun and the right air gun are each fixed by an independent mounting part (500), and the two air guns can be connected to the main body module (100) simultaneously. This arrangement allows two spaced-apart workers to grip and use them simultaneously, enabling one person to work on the left and the other on the right at the same time.

[0108] Additionally, stoppers are installed so that both the left pivot arm module (300) and the right pivot arm module (300) move within a designed pivot range. The stoppers are installed in the form of metal blocks near the hinge portions of the bracket (200) and the pivot arm module (300) to restrict the pivot arm from rotating at an angle of 135 degrees or more. This prevents the pivot arm from rotating excessively and interfering with the main body module (100) or causing structural damage.

[0109] With this configuration, in this embodiment, independent rotating arm modules (300) and air guns are provided on the left and right sides, respectively, from a single main body module (100), thereby enabling a multi-person usage environment where two workers can work simultaneously, and allowing for structurally safe use without cable interference.

[0111] Next, the magnetic adsorption part may include a plurality of magnets symmetrically arranged on the inner side of the mounting groove (510) and the tapered guide part (512), respectively, for repeatedly fixing the nozzle direction of the air gun body to a reference position, and an iron piece inserted and fixed to the outer circumference of the air gun body.

[0112] Depending on the arrangement direction of the magnet and the iron piece, when the air gun body is mounted, the nozzle can be guided to face the same set reference direction.

[0113] The above mounting part (500) may further include a rotation unit for changing the nozzle direction while the air gun body is mounted aligned in a reference direction.

[0114] The above-described rotating unit may further include a rotating seat (541) made of a support disc that rotates the mounting portion (500) from the rotating arm module (300), a plurality of shallow grooves (542) provided on the outer circumference of the rotating seat (541) to form a concave position for fixing the position, a spherical catch piece disposed in a spring receiving hole formed around the entrance of the mounting groove (510) and selectively caught into the shallow grooves (542) by the elastic force of the spring, and an angle index detection switch that electrically detects whether the rotating seat (541) has reached a specific angle such as the floor cleaning direction and provides a signal to the control unit (110).

[0115] The above-mentioned catch is configured in the shape of a metal bead and can function to fix the position when the rotating seat (541) reaches a specific angle.

[0116] The above-mentioned rotating seat (541) can be rotatably positioned so that the nozzle is turned in an inclined direction toward the bottom surface.

[0117] The angle can be fixed in the inclined direction by the above-mentioned spherical catch being caught in the above-mentioned shallow groove (542).

[0118] The above main body module (100) may be equipped with a control unit (110) for selecting and switching the operation of the rotating arm module (300) and the air gun.

[0119] The above control unit (110) can define a single mode (111) that controls only one air gun to operate, a dual mode (112) that controls the left and right air guns to operate simultaneously, and a floor cleaning mode (113) that controls both air guns to operate simultaneously while fixed at an index position in an inclined direction toward the floor surface by the rotating seat (541) based on the signal of the angle index detection switch.

[0120] The above control unit (110) can control the operation of only the air gun on the selected side in the single mode (111).

[0121] In the above dual mode (112), the left and right air guns can be controlled to operate simultaneously.

[0122] The above floor cleaning mode (113) is characterized by controlling the air gun to operate while fixed in the inclined direction.

[0123] A compressor device with improved ease of use according to another embodiment of the present invention includes a magnetic adsorption unit so that the air gun body is stably mounted on the mounting unit (500) and the nozzle direction can maintain the same reference direction during repeated use. The magnetic adsorption unit is formed of a high-performance magnet, such as a neodymium magnet, and is symmetrically arranged on both inner sides of the mounting groove (510) and the tapered guide unit (512). Each magnet is composed of a circular block with a diameter of 10 mm and a thickness of approximately 5 mm and is fixed by being embedded in the surface of the mounting groove (510). A thin iron piece is inserted and fixed on the outer circumference of the air gun body so as to be adsorbed to the magnet, and the iron piece is manufactured in the form of a steel ring with a thickness of 1 mm. Depending on the mutual arrangement direction of the magnet and the iron piece, when the air gun body is mounted, the nozzle is guided to always face the same reference direction (e.g., the front direction). This ensures that the direction remains constant even when the air gun is remounted after use.

[0124] A rotating unit is added to the mounting portion (500) so that the nozzle direction can be changed as needed while the air gun body is mounted in a reference direction. The rotating unit includes a rotating seat (541) composed of a support disc that rotates the mounting portion (500) from the rotating arm module (300). The rotating seat (541) is formed from an aluminum alloy disc with a thickness of 8 mm, and a plurality of shallow grooves (542) with a diameter of 4 mm and a depth of 2 mm are arranged on the outer circumference at 30-degree intervals.

[0125] To fix the position of the rotating seat (541), a spring receiving hole with a diameter of 5 mm is formed around the entrance of the mounting groove (510), and a spherical catch piece in the shape of a metal bead with a diameter of 4 mm is inserted into this hole along with a compression spring. The spherical catch piece is caught in the shallow groove (542) of the rotating seat (541) by the elastic force of the spring, and the position is fixed when the rotating seat (541) reaches a specific angle. Through this, the user can rotate the rotating unit by hand to change the direction of the air gun nozzle to an inclined direction toward the floor, and unintended rotation is prevented due to the action of the catch piece.

[0126] Additionally, an electric angle index detection switch is installed on the rotating seat (541). This detection switch electrically detects whether the rotating seat (541) has reached a specific angle (e.g., a 90-degree incline position corresponding to the floor cleaning mode (113)) and transmits a signal to the control unit (110). Through this, the control unit (110) can recognize whether the air gun is fixed so as to face the floor surface and can automatically switch the mode.

[0127] The main body module (100) is provided with a control unit (110) that selects and switches the operation of the rotating arm module (300) and the air gun. The control unit (110) is implemented as a microcontroller-based electronic circuit and comprehensively processes external input switches and sensor signals. The control unit (110) defines three main modes. First, the single mode (111) is a mode that controls the operation of only one air gun, so that only the left or right air gun selected by the user is activated. Second, the dual mode (112) is a mode that controls the operation of two air guns, one on the left and one on the right, simultaneously. Third, the floor cleaning mode (113) is a mode that controls the operation of both air guns simultaneously based on the signal of the angle index detection switch, while they are fixed in an inclined direction toward the floor surface by the rotating seat (541).

[0128] In single mode (111), only the selected air gun operates, and the other air gun remains in a standby state. In dual mode (112), both air guns operate at the same pressure level, allowing two workers to use them simultaneously. In floor cleaning mode (113), both air guns operate while fixed downwards, so that when the main body module (100) moves, the floor surface is blown with high-pressure air to achieve a cleaning effect.

[0129] As such, according to the present embodiment, the air gun body is always mounted in a constant direction by means of a magnetic adsorption unit, and can be switched to a special mode, such as floor cleaning, through a rotation unit. In addition, since the mode is automatically recognized and switched by the cooperative action of the angle index detection switch and the control unit (110), the user can operate the device intuitively and conveniently.

[0131] Next, the output control means (600) may include an output control switch that switches the injection pressure in stages from 0 to 3 in each air gun body of the high-pressure injection means (400).

[0132] The above control unit (110) can automatically determine the operating mode by receiving a signal from a magnetic mounting detection sensor (540) provided in each of the left mounting unit (500) and the right mounting unit (500), and an angle index status signal of the rotation unit.

[0133] The above control unit (110) can define the case where the detection count of the magnetic mounting detection sensor (540) is 0 as a dual mode (112).

[0134] In the above dual mode (112), the left and right air guns operate simultaneously, and can be controlled in conjunction with an output limiting interlock means so that the sum of the output levels of the two air guns is 3 or less.

[0135] The above control unit (110) can define the case where the detection count of the magnetic mounting detection sensor (540) is 1 as a single mode (111).

[0136] In the above single mode (111), only the air gun on the side that has been released can be controlled to operate from level 1 to level 3.

[0137] The air gun on the mounted side can be controlled to be maintained at level 0.

[0138] The control unit (110) can define a state in which the detection number of the magnetic mounting detection sensor (540) is 2 and the rotating unit is fixed at an index position in an inclined direction facing the floor surface on both sides as a floor cleaning mode (113).

[0139] In the above floor cleaning mode (113), both air guns can be controlled to operate simultaneously at 3-stage output.

[0140] The above main body module (100) may further be provided with a remaining amount display means that visually displays the amount of remaining compressed air.

[0141] The above remaining amount display means can be configured so that the operator can check it both near the main body and at the end of the rotating arm.

[0142] The above remaining amount display means may include a numeric display unit that displays the amount of compressed air remaining on the front of the main body module (100) as a number, and an arm end display unit that intuitively displays the amount of compressed air remaining on the end of each rotating arm module (300) as a bar-shaped gauge.

[0143] The above-mentioned number display unit and the above-mentioned arm end display unit are characterized by being coupled to be electrically synchronized based on a common pressure / remaining amount sensor signal.

[0144] A compressor device with improved ease of use according to another embodiment of the present invention includes an output control means (600) capable of adjusting the injection pressure stepwise according to the pressure conditions desired by the user. The output control means (600) may be implemented as a dial-type switch or a button-type switch installed in the handle portion of each air gun body. For example, a circular dial has four positions (0th stage, 1st stage, 2nd stage, 3rd stage), and as the user rotates it, the internal contact moves to generate different resistance values ​​or electrical signals. This signal is transmitted to a control unit (110) to drive a pressure control valve inside the compressor or to adjust an electronic flow control valve, thereby controlling the pressure of the compressed air supplied to the air gun stepwise. The injection pressure of each stage may be set to 0th stage (supply cut off), 1st stage (low pressure, about 2 bar), 2nd stage (medium pressure, about 4 bar), and 3rd stage (high pressure, about 6 bar).

[0145] The control unit (110) receives signals from magnetic mounting detection sensors (540) respectively placed on the left and right mounting units (500), and signals from an angle index detection switch installed on the rotation unit. Through this, the control unit (110) recognizes the current mounting status and nozzle direction of the air gun and automatically determines the operating mode.

[0146] First, when the detection count of the magnetic mounting detection sensor (540) is 0, that is, when both air guns are released from mounting, the control unit (110) defines this as dual mode (112). In dual mode (112), the left and right air guns operate simultaneously, but are linked with an output limiting interlock means to prevent the total output of the two air guns from becoming excessive. The interlock means can be implemented as internal software logic of the control unit (110) or an electronic relay circuit, and for example, if the left air gun is set to level 2, the right air gun is controlled to be allowed only up to level 1. By limiting the total output level so that it does not exceed 3, safety is ensured so that no overload occurs in the power supply unit and the compressor unit.

[0147] Second, when the detection count of the magnetic mounting detection sensor (540) is 1, that is, when only one air gun is released from mounting, the control unit (110) defines this as a single mode (111). In single mode (111), only the air gun on the side that is released from mounting is activated, and can be freely set from level 1 to level 3 according to the output control switch selected by the user. The opposite side, that is, the air gun in the mounted state, is automatically maintained at level 0 to prevent unnecessary consumption of compressed air.

[0148] Third, when the detection count of the magnetic mounting detection sensor (540) is 2 and the rotating unit is simultaneously fixed at an index position in an inclined direction facing the floor surface on both sides, the control unit (110) defines this as a floor cleaning mode (113). In this mode, the two air guns are controlled to operate simultaneously at 3-stage output, and the high-pressure air sprayed from the air guns acts uniformly over the entire floor surface to effectively remove dust and contaminants.

[0149] The main body module (100) is further equipped with a remaining amount display means that visually displays the amount of remaining compressed air. The remaining amount display means is implemented in two forms and is designed so that the operator can easily check it from various locations. First, a digital numerical display is provided on the front of the main body module (100), so that the remaining amount of compressed air collected from the internal pressure sensor is displayed in real-time as a numerical value (e.g., in bar units). Second, an analog bar gauge is placed at the end of each pivot arm module (300), so that the remaining amount of compressed air is intuitively expressed by the position of the bar needle. The bar gauge is manufactured in the form of a circular dial, which has high visual recognition, and allows the operator to easily determine the remaining amount even when working far away from the main body.

[0150] The numeric display unit and the arm end display unit are electrically synchronized based on a signal generated from a common pressure / remaining amount sensor. The sensor consists of an electronic pressure sensor installed in the compressor's internal tank, and is implemented in such a way that a single signal is transmitted to the control unit (110), and the control unit (110) branches it to transmit it to the digital display unit and the analog gauge, respectively. Through this, the display values ​​between the main body and the display device of the rotating arm end are maintained consistently.

[0151] Accordingly, according to the present embodiment, stepwise pressure control through the output control means (600), automatic mode determination through the magnetic mounting detection sensor (540) and the rotating unit, safety assurance through the output limit interlock, and intuitive air volume verification through the remaining amount display means are all possible, thereby providing convenience and safety that are differentiated from existing compressor devices.
