Description

Technical Field

[0001] This invention relates to a multi-purpose portable electric discharge device, and more specifically, to a technology that can improve work completion by supplying fluids with high viscosity, such as mortar, paste, slurry, silicone, filler, binder, oil, and resin, at a constant discharge pressure. The automatic supply without the need for physical force improves ease of use and minimizes weight, thereby enhancing portability. Background Technology

[0002] High-viscosity fluids (mortars, pastes, slurries, silica gel, fillers, binders, oils, resins) are typically not supplied as smoothly as conventional liquids due to their inherent physical properties. This is because high-viscosity fluids have higher internal friction and greater friction with the walls of pipes and pumps.

[0003] The industries that use this high-viscosity fluid can be broadly categorized into fuel, chemical, food, pharmaceutical, construction, plastics, various manufacturing industries, waste treatment, semiconductors, secondary batteries, and many other fields. In order to supply in large quantities, large-scale pumps must be used.

[0004] However, installing and using such a large-capacity pump is actually quite difficult in workplaces or locations where small amounts of high-viscosity fluid are required, and it is not suitable to install and use existing large-capacity pumps when it is necessary to relocate the work site while supplying high-viscosity fluid.

[0005] Therefore, silicone guns are widely used to supply small quantities of high-viscosity fluids, such as silicone injection. These silicone guns operate as follows: when the user pulls a trigger (lever), the force is transmitted to the cylinder, pushing it forward and discharging the silicone.

[0006] However, existing silicone guns only use finger pressure to dispense silicone, which increases user fatigue. Additionally, it is difficult for inexperienced users to adjust the silicone dispensing pressure.

[0007] [Existing Technical Documents] [Patent Documents] Patent Document 0001: Korean Patent No. 10-0829387 (Automatic Supply Device for High Viscosity Fluids) Patent Document 0002: Korean Patent No. 10-2164073 (Silicone Gun) Summary of the Invention The problem the invention aims to solve The present invention is proposed to solve the problems mentioned above. Its purpose is to provide a multi-purpose portable electric discharge device that can effectively discharge high-viscosity fluids such as mortar, paste, slurry, silicone, filler, binder, oil, and resin, and supply them to the required part. It can maintain a constant supply pressure so that even unskilled personnel can use it easily. Moreover, it adopts an electric method instead of a manual method, thereby improving the convenience of use and reducing fatigue.

[0008] means for solving problems The present invention aims to provide a multi-purpose portable electric discharge device, comprising: a main body having an internal space; a fluid delivery unit disposed inside the main body, wherein a suction port is formed at the lower part of the fluid delivery unit and a discharge port is formed at the front part of the fluid delivery unit, the suction port being used to draw in fluid to be discharged, and the discharge port being used to discharge the drawn-in fluid at high pressure; a motor pump coupled to one side of the fluid delivery unit, which forcibly delivers fluid toward the discharge port by means of the rotational force of the motor; a battery supplying electrical energy to the motor pump; and a working switch controlling the application of a working signal to the motor pump.

[0009] Furthermore, the present invention is characterized in that a hose for continuously supplying fluid or a reservoir filled with a predetermined amount of fluid is selectively connected to the inlet of the fluid delivery unit.

[0010] Furthermore, the present invention is characterized in that the nozzle is threadedly connected to the outlet of the fluid delivery unit, and a first threaded portion formed on the outer circumferential surface of the pipe and a second threaded portion formed on the inner side of the pipe are respectively formed on the outlet, so that the nozzle can be selectively connected to the first threaded portion or the second threaded portion depending on the type of nozzle.

[0011] Furthermore, the present invention is characterized in that a guide plate is integrally formed at the end portion of the nozzle in a direction perpendicular to the fluid discharge direction.

Furthermore, in the process of describing the present invention, detailed descriptions of related known functions or structures will be omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the present invention.

[0025] The multi-purpose portable electric discharge device of the present invention is a device for effectively discharging high-viscosity fluids such as mortar, paste, slurry, silicone, filler, binder, oil, and resin. In addition, it can also discharge liquids such as washing water.

[0026] like Figure 1 As shown, the multi-purpose portable electric discharge device of the present invention is characterized by comprising: a main body 100 having an internal space; a fluid delivery unit 200 disposed inside the main body 100, wherein a suction port 210 is formed at the lower part of the fluid delivery unit 200 and a discharge port 220 is formed at the front part of the fluid delivery unit 200, the suction port 210 being used to draw in fluid to be discharged and the discharge port 220 being used to discharge the drawn-in fluid at high pressure; an electric motor pump 300 coupled to one side of the fluid delivery unit 200, which forcibly delivers fluid toward the discharge port 220 by means of the rotational force of the electric motor; a battery 400 supplying electrical energy to the electric motor pump 300; and a working switch 500 controlling the application of a working signal to the electric motor pump 300.

[0027] The main body 100 has an internal space for housing the fluid delivery unit 200 and the electric motor pump 300. Furthermore, the main body 100 is shaped like a gun with the handle 110 located below, for ease of use.

[0028] As shown in the figure, the fluid delivery section 200 of the present invention is formed as " The device is shaped like a "" with an intake port 210 at the bottom to draw in the fluid to be discharged, and an outlet port 220 at the front to discharge the drawn-in fluid under high pressure.

[0029] The fluid delivery unit 200's inlet 210 can be supplied in two ways: either by using a hose for continuous fluid supply, or by using a reservoir filled with a predetermined amount of fluid, as shown in the figure. This can be changed depending on the fluid supply method or the type of fluid. For example, in the case of wash water used in a car wash, the fluid is preferably supplied via a hose; however, if the viscosity is high and the required fluid volume is small, a reservoir containing the fluid can be used.

[0030] Furthermore, the electric motor pump 300 of the present invention is configured to be coupled to one side of the fluid delivery section 200 so as to generate a suction force at the suction port 210 by utilizing the rotational force of the electric motor, and the suctioned fluid is forcibly delivered to the discharge port 220. The electric motor pump 300 can be used in various ways, among which, it is preferable to use a method in which an impeller installed inside the fluid delivery section 200 rotates by means of the rotation of the electric motor to deliver fluid.

[0031] The battery 400 is the energy source that provides electrical power to the electric motor pump 300. Of course, it is also possible to power the pump by connecting a separate power cord without using the battery 400, but for the sake of portability, it is preferable to use a rechargeable battery 400. In this case, the battery 400 is attached to the main body 100, and the attachment method is shown in the figure. It can be attached to the lower side of the handle 110 of the main body 100.

[0032] The operating switch 500 applies an operating signal to the electric motor pump 300 for discharge control. The operating switch 500 is also located on the handle 110 for ease of operation; when the operating switch 500 is pressed by pulling, an operating signal is applied to the electric motor pump 300 to discharge fluid.

[0033] Another feature of the present invention configured as described above is that the outlet 220 of the fluid delivery unit 200 is not used directly, but various types of nozzles 600 are combined with the outlet 220, so that it can be used for multiple purposes depending on the type of fluid.

[0034] In other words, a nozzle 600 is threadedly connected to the outlet 220 of the fluid delivery unit 200 of the present invention. The outlet 220 is formed with a first threaded portion 221 formed on the outer circumferential surface of its pipe and a second threaded portion 222 formed on the inner side of its pipe, so that the nozzle 600 can be selectively connected to the first threaded portion 221 or the second threaded portion 222 depending on the type of nozzle 600.

[0035] Figures 2 to 3 A nozzle 600 of a first embodiment is shown attached to a first threaded portion 221 of an outlet 220. The nozzle 600 has a shape that gradually narrows in diameter forward. Fluids suitable for such nozzle 600 include cement, mortar, adhesive, or epoxy resin or polyurethane used for tile construction.

[0036] and, Figures 4 to 5 The nozzle 600 shown is a second embodiment of the nozzle 600 that is attached to the second threaded portion 222, and is shaped as a nozzle 600 that is attached to a hose. Preferably, the nozzle 600 of the second embodiment is suitable for various fluids such as oils and lubricants.

[0037] Figure 6The irregularly shaped connector sleeve 610, which is incorporated into the outlet 220 of the present invention, has threads formed on the outer side of one side and threads formed on the inner side of the opposite side. Therefore, the nozzle 600 can be directly incorporated into the outlet 220, or the outlet 220 and the nozzle 600 can be connected through the irregularly shaped connector sleeve 610. Thus, it has the advantage of being able to install nozzles 600 of various specifications.

[0038] Figures 7 to 8 Another embodiment of the invention is shown, in which a heating structure capable of heating the fluid via a power source from a battery 400 is further added to the fluid delivery section 200. Specifically, the fluid delivery section is configured such that multiple heating rods 700 are provided on the pipe of the outlet 220, which heat the pipe of the outlet 220, thereby heating the fluid flowing through the pipe of the outlet 220. As shown in the figure, the pipe of the outlet 220 refers to the portion located inside the main body 100, not the portion outside the main body 100. Therefore, to improve heating efficiency, it is preferable to make this section of the pipe at the outlet 220 longer.

[0039] Typically, the viscosity of high-viscosity fluids increases as the temperature decreases. Therefore, with the heating structure described above, the fluid temperature increases, leading to a decrease in fluid viscosity, which makes it easier to discharge.

[0040] To describe the heating structure in more detail, a plurality of C-shaped fixing clips 223 are formed circumferentially on the outer circumferential surface of the outlet 220. The heating rod 700 is inserted into and engaged in the fixing clips 223 thus formed.

[0041] As a result of this configuration, the heating rods 700 are arranged in a circular pattern on the outer circumference of the outlet 220 pipe, thus forming a radial arrangement.

[0042] Furthermore, multiple semi-partitions 224 are spaced apart inside the pipe of the outlet 220. As the fluid collides with the semi-partitions 224, the particles inside the fluid are mixed, thereby further improving the heat transfer effect. The semi-partitions 224 are alternately formed in the upper and lower parts inside the pipe of the outlet 220, so that the fluid moves alternately in the upper and lower parts, thereby delaying the residence time. In this case, the cross-sectional area of ​​the semi-partitions 224 occupies 50% to 80% of the moving area inside the pipe of the outlet 220, thereby improving the heat transfer efficiency and mixing efficiency.

[0043] The pipe of the outlet 220 of the present invention, constructed as described above, is preferably made of metal to improve heat transfer efficiency, and the half-partition 224 is also preferably made of the same metal material.

[0044] also, Figure 9Another embodiment is shown in which a guide plate 601 is integrally formed at the end of the nozzle 600 of the present invention in a direction perpendicular to the discharge direction. As described above, if the guide plate 601 is integrally formed at the end of the nozzle 600, the guide plate 601 acts as a barrier during operations such as tile grouting, preventing fluids such as silicone or mortar from overflowing to the side, and allowing them to be injected into the accurate position.

[0045] The present invention has been described above with reference to the embodiments described above. However, various modifications can be made within the scope of the technical concept of the present invention.
