(11) According to the present disclosure, an oil gun for an automatic fluid pump includes, as shown in FIG. 1 to FIG. 8, a case 100 including a handle part 110, which has a switch S installed on an outer portion so that a suction pumping part coupled to a lower portion of a suction hose 20 can operate with power supplied from a battery B, and of which one side end portion is coupled to one end portion of a supply hose 40 so that the supply hose 40 is fixed, and a gun nozzle coupling part 120 extending downward from the other side end portion of the handle part 110 so as to be bent, and a flow path member 200 installed so that a flow path is formed inside the handle part 110 and the gun nozzle coupling part 120 of the case 100, wherein the flow path member 200 includes a connector 210 installed and fixed to one side end portion of the handle part 110, a connecting hose 220 of which one end is fitted and fixed to the connector 210, and a joint member 230 formed to be bent so that one end of the joint member 230 is fitted to the other end of the connecting hose 220 and one side portion of a gun nozzle 400 is fitted to the other end of the joint member 230.

(12) In the drawings, reference numeral 900 indicates a spring that returns the switch S to its original position by elastic force after the switch S is operated so that power of the battery B is supplied to the suction pumping unit 10.

(13) Meanwhile, the connecting hose 220 is formed in a bellows type.

(14) In addition, a fastening part 130 having a thread is formed on an outer surface of the one side end portion of the handle part 110 to which the connector 210 is fixed, and a coupling joint 300 is fastened to the fastening part 130 so that an outer surface of the one end portion of the supply hose 40 is compressed and fixed.

(15) Meanwhile, the joint member 230 is inclined so that a flow path of a bent part is placed higher than a flow path of a part where the upper portion of the gun nozzle 400 is fitted.

(16) In addition, a plurality of locking grooves 410 are formed at regular intervals on an outer portion of the gun nozzle 400 so as to be caught in an inlet of a container 60, thereby preventing the gun nozzle 400 from being inserted more than a certain amount and preventing the gun nozzle 400 from being arbitrarily withdrawn from the inlet.

(17) Meanwhile, a sensor 700 for detecting an amount of fluid supplied to the inside of the container 60 is installed on the other side portion of the gun nozzle 400, of which the one side portion is fitted to the joint member 230.

(18) In addition, the case 100 in which the flow path member 200 is installed so that the flow path is formed inside the handle part 110 and the gun nozzle coupling part 120 may be divided into an upper case 100a and a lower case 100b that can be assembled and disassembled, and a first seating groove 131 and a second seating groove 121 are respectively formed on one end and the other end of each of the upper case 100a and the lower case 100b, so that one side portion of the connector 210 is inserted and seated in the first seating groove 131 so as to be fixed and the other side portion of the joint member 230 where the upper portion of the gun nozzle 400 is fitted is seated in the second seating groove 121.

(19) Meanwhile, a storage hole 34 in which the gun nozzle 400 is inserted and stored is formed in a lower portion of a body part 30, where the suction hose 20 and the supply hose 40 are coupled so as to communicate with each other.

(20) According to the present disclosure structured in this way, the connector 210 fitted and coupled to the connecting hose 220 is seated on the first seating groove 131 of the upper case 100a, and the joint member 230 fitted and coupled to the connecting hose 220 is inserted and seated on the second seating groove 121 of the upper case 100a, and then the lower case 100b is coupled to the upper case 100a, thereby forming the case 100 in which the flow path is formed.

(21) Herein, since the connecting hose 220 is formed in a bellows type, the connection hose 220 is positioned inside the case 100 while varying in length depending on a distance between the connector 210 and the connection member 230.

(22) Meanwhile, the switch S is operably installed on the outside of the case 100 formed by coupling the upper case 100a and the lower case 100b so as to allow the suction pumping part 10 coupled to the lower portion of the suction hose 20 to operate with power supplied from the battery B.

(23) In addition, after assembling the case 100 as described above, the coupling joint 300 is fastened to the fastening part 130 formed on the outer surface of the handle part 110 so that the outer surface of the one end of the supply hose 40 is compressed and fixed, thereby firmly maintaining airtightness.

(24) Therefore, in order to supply fluid stored inside the tank 50 to the inside of the container 60 of a user, an operator inserts the suction hose 20, of which the upper end is coupled to an inlet 33 of the body part 30, into the tank 50, places the other side portion of the supply hose 40, of which the one side end portion is fixedly coupled to the outlet 32 of the body part 30, in the inlet of the container 60, and then inserts the gun nozzle 400 to the inside of the container 60 through the inlet while holding the handle part 110 formed on the case 100 with a hand.

(25) At this time, an insertion amount of the gun nozzle 400 that is inserted into the container 60 is determined according to a position where the locking grooves 410 formed on the outer portion of the gun nozzle 400 is caught on a frame of the container 60 having the inlet during insertion of the gun nozzle 400 into the container 60. Therefore, the insertion amount of the gun nozzle 400 that is inserted into the container 60 can be controlled by an operator through the locking grooves 410. In addition, the gun nozzle 400 is suppressed from being arbitrarily drawn out and dropped from the inlet of the container 60.

(26) Of course, it is also possible to maintain a state in which the gun nozzle 400 is inserted into the container 60 by coupling a locking member 500 having a locking jaw 510 to the outer portion of the gun nozzle coupling part 120 so that the locking member 500 can be caught on a surface of the container when the gun nozzle 400 is inserted into the inlet of the container 60.

(27) In addition, it is also possible to prevent the gun nozzle 400 from being separated from the container 60 by means of a stem holder 600 by installing the stem holder 600 to the outer portion of the gun nozzle 400, wherein the stem holder 600 is detachably attached to the container 60.

(28) Meanwhile, it is more preferable that the stem holder 600 to be detachably attached to the container 60 is integrally formed with the locking member 500 that is coupled to the outer portion of the gun nozzle 400, so that the locking member 500 is caught on the surface of the container 60, thereby maintaining a state in which the gun nozzle 400 is inserted into the container 60 and, at the same time, the stem holder 600 prevents the gun nozzle 400 from being separated from the container 60 during use.

(29) In the state where the gun nozzle 400 is inserted into the container 60 as described above, if an operator manipulates the switch S, the fluid stored in the tank 50 flows into the suction hose 20 by the suction force generated by the suction pumping part 10 which operates with the power from the battery B, and the fluid introduced into the suction hose 20 flows into the body part 30 through the inlet 33 and then is discharged to the outside through the outlet 32, wherein the fluid discharged to the outside of the body part 30 flows into the flow path formed inside the case 100 through the supply hose 40, of which the one side portion is fixedly coupled to the outlet 32, and the fluid introduced into the flow path is supplied to the inside of the container 60 through the gun nozzle 400.

(30) At this time, the fluid introduced into the flow path formed inside the case 100 is supplied to the inside of the container 60 through the gun nozzle by sequentially passing through the connector 210 fixedly installed on the handle part 110, the connecting hose 220 fixedly fitted to the connector 210, and the bent joint member 230 fitted to the connecting hose 220 and the gun nozzle 400.

(31) Meanwhile, after the fluid stored in the tank 50 is supplied to the container 60 as described above, the sensor 700 detects it and transmits a signal to the control unit 800, and the control unit 800 cuts off the power of the battery B that is supplied to the suction pumping part 10 according to the detection signal from the sensor 700 so as to block the fluid from being supplied to the inside of the container 60.

(32) At this time, it is possible to prevent the fluid from remaining in the connecting hose 220 since the joint member 230 is formed to be inclined so that the flow path at the bent part is positioned higher than the flow path at the part where the upper portion of the gun nozzle 400 is fitted.

(33) In addition, in order to prevent contamination of the gun nozzle 400 due to contact of the gun nozzle 400 with external objects after filling the container 60 as described above, the gun nozzle 400 is inserted into the storage hole 34 formed at the lower portion of the body part 30 for storage.

(34) Although the preferred embodiments of the present disclosure have been described in detail above, the scope of the present disclosure is not limited thereto, and various modifications and improvements made by those skilled in the art by using the basic concept of the present disclosure defined in the following claims also fall within the scope of the present disclosure.
