Description

Multi-purpose portable electric dispensing device

[0001] The present invention relates to a multi-purpose portable electric dispensing device, and more specifically, to a technology that improves work completion by supplying fluids such as mortar, paste, sludge, silicone, filler, adhesive, oil, and resin with high viscosity at a constant dispensing pressure, improves ease of use by supplying automatically without using physical force, and improves portability by minimizing weight.

[0002]

[0003] In general, high-viscosity fluids (mortar, paste, sludge, silicone, filler, adhesive, oil, resin) are not supplied as smoothly as ordinary liquids due to the inherent properties of their physical properties. This is because high-viscosity fluids have high internal friction and high frictional force with the walls of pipes and pumps.

[0004]

[0005] These high-viscosity fluids are used in a wide variety of business sectors, including fuel, chemicals, food, pharmaceuticals, construction, plastics, various manufacturing industries, waste treatment, semiconductors, and secondary batteries, and large-sized pumps must be used to supply them in large quantities.

[0006]

[0007] However, installing and using such large-capacity pumps is practically difficult for tasks or locations requiring small quantities of high-viscosity fluids, and existing large-capacity pumps are not suitable for situations where high-viscosity fluids must be supplied while moving between locations.

[0008]

[0009] Therefore, a commonly used silicone gun is utilized to supply small amounts of high-viscosity fluids, such as in silicone injection. The silicone gun is designed so that when a user pulls a lever, the pulling force is transmitted to a cylinder that pushes it forward to eject the silicone.

[0010] However, conventional silicone guns eject silicone using only finger strength, which increases user fatigue and makes it difficult to control the silicone ejection pressure when used by unskilled users.

[0011]

[0012] The present invention was devised to solve the above-mentioned problems, and aims to provide a multi-purpose portable electric dispensing device that effectively dispenses high-viscosity fluids such as mortar, paste, sludge, silicone, filler, adhesive, oil, and resin to the necessary parts, while maintaining a constant supply pressure so that even unskilled workers can use it easily, and can be operated electrically rather than manually to increase convenience of use and reduce fatigue.

[0013]

[0014] The present invention is characterized by comprising: a body portion having an internal installation space; a fluid transfer portion installed inside the body portion, having an intake port formed at the bottom for sucking in a fluid to be discharged and a discharge port formed at the front for discharging the sucked fluid at high pressure; a motor pump coupled to one side of the fluid transfer portion for forcibly transferring the fluid toward the discharge port by the rotational force of a motor; a battery for supplying electrical energy to the motor pump; and an operating switch for controlling an operating signal to the motor pump.

[0015]

[0016] In addition, the suction port of the fluid transfer unit is characterized by being selectively connected to either a hose that continuously supplies fluid or a storage container filled with a certain amount of fluid.

[0017]

[0018] In addition, a nozzle is screw-coupled to the discharge port of the fluid transfer unit, wherein a first screw portion formed on the outer circumference of the pipe of the discharge port and a second screw portion formed on the inner side of the pipe are respectively formed, and the nozzle is selectively coupled to either the first screw portion or the second screw portion depending on the type of nozzle.

[0019]

[0020] A multi-purpose portable electric discharge device characterized by having a guide plate integrally formed at the end of the nozzle in a direction perpendicular to the fluid discharge direction.

[0021]

[0022] The present invention applies an electric method to enable the supply of high-viscosity fluids (mortar, paste, sludge, silicone, filler, adhesive, oil, resin) at a constant pressure, thereby increasing the ease of use for unskilled workers and improving the quality of work completion.

[0023]

[0024] In addition, the present invention has the advantage of being easy to carry and use while moving to various locations due to its lightweight design, and has the effect of reducing work fatigue.

[0025]

[0026] In addition, the present invention has the effect of being usable for various purposes by allowing various types of nozzles to be further coupled to the discharge hole to have various discharge forms suitable for the type of fluid.

[0037]

[0038] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Furthermore, in describing the present invention, detailed descriptions of related known functions or configurations are omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the present invention.

[0039]

[0040] The multi-purpose portable electric dispensing device of the present invention is a device for effectively dispensing high-viscosity fluids such as mortar, paste, sludge, silicone, filler, adhesive, oil, and resin, and is capable of dispensing not only high-viscosity fluids but also liquids such as washing water.

[0041]

[0042] The configuration of the multi-purpose portable electric discharge device of the present invention is characterized by comprising: a body part (100) having an internal installation space formed as shown in FIG. 1; a fluid transfer part (200) installed inside the body part (100), having a suction port (210) formed at the bottom for sucking in fluid to be discharged, and a discharge port (220) formed at the front for discharging the sucked fluid at high pressure; a motor pump (300) coupled to one side of the fluid transfer part (200) and forcibly transferring fluid in the direction of the discharge port (220) by the rotational force of a motor; a battery (400) that supplies electrical energy to the motor pump (300); and an operating switch (500) that controls an operating signal to the motor pump (300).

[0043]

[0044] The above body part (100) has an internal installation space formed therein so that a fluid transfer part (200) and a motor pump (300) can be housed therein. In addition, the body part (100) is shaped like a gun with a handle (110) at the bottom, making it easy to use.

[0045]

[0046] As shown in the drawing, the fluid transfer unit (200) of the present invention is formed in the shape of a "ㄱ", and a suction port (210) for sucking in fluid to be discharged is formed at the bottom, and a discharge port (220) for discharging the sucked fluid with high pressure is formed at the front.

[0047] The suction port (210) of the above fluid transfer unit (200) can be supplied in two ways: a hose that continuously supplies fluid may be connected, or a storage container filled with a certain amount may be connected as shown in the drawing. This can be changed depending on the fluid supply method or the type of fluid. That is, in the case of washing water used in a car wash, it is preferable to supply it in the form of a hose, but if the viscosity is high and the amount of fluid to be supplied is small, a storage container containing fluid may be connected.

[0048]

[0049] The motor pump (300) of the present invention is coupled to one side of the fluid transfer unit (200) and is configured to generate suction force at the suction port (210) using the rotational force of the motor, and to forcibly transfer the sucked fluid toward the discharge port (220). Various methods of motor pump (300) may be implemented, and among them, a method in which an impeller installed inside the fluid transfer unit (200) rotates by the rotation of the motor to transfer the fluid is preferred.

[0050]

[0051] The above battery (400) is an energy source that supplies electrical energy to the motor pump (300). Of course, power can be supplied by connecting a separate power line without using the battery (400), but it is preferable to use a rechargeable battery (400) to increase portability. At this time, the battery (400) is coupled to the body part (100), and the coupling method can be coupled to the lower part of the handle (110) of the body part (100) as shown in the drawing.

[0052]

[0053] The above-mentioned operating switch (500) applies an operating signal to the motor pump (300) to control the discharge. The above-mentioned operating switch (500) is also installed on the handle (110) to facilitate control, and when the operating switch (500) is pressed in a pulling manner, an operating signal is applied to the motor pump (300) to discharge fluid.

[0054]

[0055] Another feature of the present invention, as described above, is that the discharge port (220) of the fluid transfer unit (200) is not used as is, but is coupled with various types of nozzles (600) so that it can be used for various purposes according to the type of fluid.

[0056] That is, in the present invention, a nozzle (600) is screw-coupled to the discharge port (220) of the fluid transfer unit (200), wherein a first screw portion (221) formed on the outer circumference of the pipe of the discharge port (220) and a second screw portion (222) formed on the inner side of the pipe are respectively formed, and the nozzle (600) is selectively coupled to the first screw portion (221) or the second screw portion (222) depending on the type of nozzle.

[0057]

[0058] FIGS. 2 and 3 show a nozzle (600) according to a first embodiment coupled to a first screw portion (221) of a discharge port (220), and is a nozzle (600) in which the diameter narrows toward the front. Suitable fluids for such a nozzle (600) include cement, mortar, adhesive, epoxy, or urethane used in tile installation.

[0059] And the nozzle (600) of FIGS. 4 and 5 represents a nozzle (600) according to a second embodiment that is coupled to a second screw portion (222), and is in the form of a nozzle (600) coupled together with a hose. It is preferable that a fluid such as various oils or lubricants be applied to the nozzle (600) of the second embodiment.

[0060]

[0061] FIG. 6 shows a shaped nipple socket (610) coupled to the discharge port (220) of the present invention, wherein one side has a screw thread formed on the outer side and the other side has a screw thread formed on the inner side. Accordingly, although a nozzle (600) may be directly coupled to the discharge port (220), the shaped nipple socket (610) is connected between the discharge port (220) and the nozzle (600) as an intermediary, thereby providing the advantage that nozzles (600) of various sizes can also be mounted.

[0062]

[0063] FIGS. 7 and 8 illustrate another embodiment of the present invention, in which a heating configuration is further added to the fluid transfer unit (200) to heat the fluid using the power of the battery (400). That is, the structure is formed such that a plurality of heating rods (700) are installed on the conduit of the discharge port (220) in the fluid transfer unit, so that the heating rods (700) heat the conduit of the discharge port (220), thereby heating the fluid passing through the conduit of the discharge port (220). Here, the conduit of the discharge port (220) does not refer to a part located on the outside of the body part (100), but rather refers to a part located on the inside of the body part (100) as shown in the drawings. Therefore, to increase heating efficiency, it is preferable to form this section of the discharge port (220) longer.

[0064]

[0065] Generally, since the viscosity of high-viscosity fluids increases as the temperature decreases, having a heating structure like this offers the advantage of lowering viscosity as the fluid temperature rises, making discharge easier.

[0066]

[0067] To explain the heating structure in more detail, a plurality of fixing clips (223) formed in a "C" shape are formed along the circumference of the outer surface of the pipe of the discharge port (220). A heating rod (700) is connected by being inserted into the fixing clips (223) formed in this manner.

[0068] As configured in this way, the heating rods (700) are arranged in a circular pattern on the outer surface of the discharge port (220) and radially arranged.

[0069]

[0070] In addition, a plurality of counter-walls (224) are installed at intervals inside the discharge port (220) conduit, so that as the fluid strikes the counter-walls (224), particles inside the fluid are mixed and the heat transfer effect is further enhanced. The counter-walls (224) are formed alternately in the upper and lower parts inside the discharge port (220) conduit, so that the fluid moves alternately between the upper and lower parts to increase the residence time. At this time, the cross-sectional area of ​​the counter-walls (224) is 50 to 80% of the area of ​​movement inside the discharge port (220) conduit to increase the heat transfer efficiency and mixing efficiency.

[0071]

[0072] In order to increase heat transfer efficiency, it is preferable that the discharge port (220) of the present invention be made of metal, and it is also preferable that the counterwall (224) be made of the same metal material.

[0073]

[0074] In addition, FIG. 9 shows another embodiment 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 direction of fluid discharge. When the guide plate (601) is integrally formed at the end of the nozzle (600) as described above, the guide plate (601) functions to block when performing tasks such as tile grouting, and the fluid, such as silicone or mortar, can be injected into the correct position without leaking out to the side.

[0075]

[0076] Although the present invention has been described above with reference to the embodiments, it is understood that various modifications are possible within the scope of the technical spirit of the present invention.
