FIG. 1 is a side sectional view illustrating a spraying device according to an embodiment of the present invention. Fig. 2 is a diagram illustrating a state in which the movable portion in fig. 1 moves to eject the content.
Referring to fig. 1 and 2, an injection apparatus 1 according to an embodiment of the present invention may include a receiving portion 100, a nozzle portion 200, a valve portion 300, and an injection portion 400.
The storage unit 100 according to one embodiment of the present invention can communicate with a nozzle unit 200 that ejects the content F to the outside, and can store the content F and the gas G.
In the present invention, the content F may be formed of a fluid such as a cosmetic, a shaving cream, or a medical adhesive that is a composition for joining damaged tissues without a surgical operation, which can be applied to the skin of a user. The viscous substance may be stored in the storage unit 100 at ordinary times and may be ejected to the outside.
Referring to fig. 1 and 2, the receiving portion 100 may include a first body portion 110, a second body portion 130, and a movable portion 150.
Referring to fig. 1 and 2, the first body 110 according to an embodiment of the present invention is formed to be hollow and may contain a gas G.
If referring to fig. 1, the first body part 110 may include a first body 111, a seating part 115. The first body 111 is hollow, and one side (upper side with reference to fig. 1) can be connected to the nozzle portion 200, and the other side (lower side with reference to fig. 1) opposite thereto can be connected to the base portion 115.
The first body 111 may be formed in a cylindrical shape, but is not limited thereto, and may be variously modified such that at least one or more flat surfaces are formed along the circumference of the side surface.
The first body 111 according to an embodiment of the present invention may share a longitudinal central axis with a second body 130, which will be described later, and be disposed outside the second body 130. The gas G supplied from the outside to the housing part 100 can pressurize the movable part 150 disposed inside the second body part 130 in a preset direction (upward direction with reference to fig. 1).
Therefore, the state of applying pressure to the content F accommodated in the second body 130 can be maintained, and the pressure of the gas G supplied to the accommodating portion 100, specifically, to the inside of the first body 110 has an effect that a region on one side communicating with the nozzle portion 200 in the inside of the second body 130, that is, an upper side (with reference to fig. 1) of the movable portion 150 can be maintained in a state filled with the content F.
Further, since the upper region (with reference to fig. 1) of the movable portion 150 is kept in a pressure-receiving state by the gas G in a state filled with the content F, if the passage 331 formed in the valve portion 300 described later communicates with the passage 201 formed in the nozzle portion 200, the content F can be efficiently and quickly ejected to a desired position by the pressure of the gas G.
Further, since the upper region (with reference to fig. 1) of the movable part 150, which is a region provided in advance in the second body part 130, is in a state of continuously receiving pressure from the gas G in the interior of the housing part 100, there is an effect that the flow path 201 can be opened and closed by the valve part 300 to rapidly spray the content F in a desired direction regardless of the angle at which the user grasps the spraying device 1.
Referring to fig. 2, the base part 115 according to an embodiment of the present invention is connected to the first body 111, and may be connected to a lower end of the first body 111. Referring to fig. 1 and 2, a predetermined region of the seating portion 115 according to an embodiment of the present invention may be insertedly coupled to the first body 111.
However, the inner diameter of the base part 115 may be formed larger than the outer diameter of the first body 111, and the first body 111 may be inserted into and connected to the base part 115.
Referring to fig. 1 and 2, a sealing member S may be disposed between one surface of the base portion 115 and one surface of the first body 111 facing each other. The sealing member S may be formed of an elastically deformable material, and may be respectively attached to the base portion 115 and the first body 111 in an interference fit manner in a process of inserting the base portion 115 into the first body 111.
Therefore, there is an effect that the gas G supplied from the outside to the inside of the first main body portion 110 can be prevented from flowing out to the outside through the space formed between the first main body 111 and the base portion 115, so that the inside of the first main body portion 110, specifically, a state in which the gas G contained inside the first main body 111 pressurizes the movable portion 150 in a preset direction (upper side with reference to fig. 1) can be maintained.
Referring to fig. 1 and 2, the sealing member S according to an embodiment of the present invention may be disposed between the first body 111 and the base 115 facing each other in close contact with each other, and may be formed to extend circumferentially with respect to a longitudinal center axis of the first body 110.
The base part 115 according to an embodiment of the present invention may have a groove part formed along the circumference of the outer circumferential surface with reference to the center, in a groove part shape, in which the sealing member S can be seated. Therefore, the sealing member S can be easily attached to the base portion 115, and the base portion 115 on which the sealing member S is mounted can be inserted into the first body 111 to be stably fixed in position.
The first body 111 and the base part 115 according to an embodiment of the present invention may be coupled in a hanging manner. However, the present invention is not limited to this, and various modifications are possible, and for example, bonding by ultrasonic welding or the like is possible.
Referring to fig. 1 and 2, the second body portion 130 according to an embodiment of the present invention is connected to the first body portion 110, and has a hollow interior to receive the content F therein.
The second body 130 according to an embodiment of the present invention is formed in a cylindrical shape and is disposed inside the first body 110, specifically, inside the first body 111, but is not limited thereto, and may be variously modified such that at least one or more flat surfaces are formed along the circumference of the second body 130 with respect to the longitudinal center axis thereof.
Referring to fig. 1 and 2, the lower end portion of the second body portion 130 (with reference to fig. 1) may be disposed at a relatively higher position than the lower end portion of the first body 111 (with reference to fig. 1).
Therefore, the gas G contained between the inner surface of the first body 111 and the outer surface of the second body can apply pressure in the upper direction from the lower side (with reference to fig. 1) of the movable portion 150 located inside the second body through the lower end portion of the second body.
Further, as the pressure is applied from the lower side to the upper side of the movable portion 150 in the second body, the state of being filled with the content F can be maintained at the upper side of the movable portion 150, and if the flow path 201 formed in the nozzle portion 200 is opened by the valve portion 300, the movable portion 150 moves along the flow path 201 side by the pressure, and the content F can be rapidly ejected to the outside.
Referring to fig. 1 and 2, the movable portion 150 according to an embodiment of the present invention can contact an upper portion of the base portion 115. Therefore, the movable portion 150 can be prevented from being detached from the second body portion 130.
Referring to fig. 1 and 2, the movable portion 150 according to an embodiment of the present invention may be formed of an elastically deformable material, and an outer circumferential surface of the movable portion 150 may be in close contact with an inner circumferential surface of the second body portion 130, so that the gas G or the contents F may be prevented from flowing out through a gap between the movable portion 150 and the second body portion 130.
Referring to fig. 1 and 2, the nozzle unit 200 according to an embodiment of the present invention may be formed with a flow path 201 inside to spray the contents F to the outside so that the contents F can flow.
Referring to fig. 1 and 2, a valve 300 is connected to the nozzle 200, and the flow path 201 formed in the nozzle 200 is opened and closed by driving the valve 300, whereby the ejection of the content F contained in the containing unit 100, specifically, the second body 130 can be controlled.
Referring to fig. 1 and 2, the flow path 201 formed in the nozzle unit 200 according to one embodiment of the present invention is formed in a vertical direction (vertical direction with reference to fig. 1), but is not limited thereto, and may be variously modified and implemented, for example, a flow path 201 is formed in a horizontal direction (horizontal direction with reference to fig. 2) by forming a bent section at least 1 time or more.
Referring to fig. 1 and 2, the valve unit 300 according to an embodiment of the present invention is connected to the nozzle unit 200, and opens and closes a flow path 201, which is a flow path for the contents F formed in the nozzle unit 200.
If referring to fig. 1, the valve portion 300 may include a pressing portion 310, a valve stem 330. The pressing portion 310 can contact with a user and can be exposed to the outside. Therefore, the user can press the pressing portion 310 to move the valve rod 330 connected to the pressing portion 310 along the longitudinal central axis, and the valve rod 330 can move to open and close the flow path 201.
Although not shown in the drawings, the valve portion 300 may include an elastic member, and the user pushes the pressing portion 310 to open the flow path 201 formed in the nozzle portion 200, and moves away from the pressing portion 310, and if the pressure applied to the pressing portion 310 is removed, the position of the valve portion 300 is restored to the original position by the elastic restoring force of the elastic member, so that the flow path 201 may be closed, and the injection of the content F contained in the second body portion 130 to the outside may be interrupted as the flow path 201 is closed.
Referring to fig. 1 and 2, a passage flow path 331 may be formed in the valve stem 330 according to an embodiment of the present invention, and a section provided in advance in the valve stem 330 may be formed through the passage flow path 331.
Therefore, before the user comes into contact with the valve portion 300, the passage 331 is disposed at a position not communicating with the passage 201 formed in the nozzle portion 200, and the user comes into contact with the valve portion 300, and if pressure is applied in a preset direction (a direction from the left side to the right side with reference to fig. 2), the valve portion 300, specifically, the pressing portion 310 and the stem 330 move, and at the same time, the passage 331 formed in the valve portion 300 communicates with the passage 201 formed in the nozzle portion 200, and the passage 201 as a flow path for the content F is opened, whereby the content F can be ejected to the outside.
Referring to fig. 1 and 2, the injection part 400 according to an embodiment of the present invention is connected to the first body part 110, and may form an inflow path of gas G supplied from the outside. Specifically, the injection part 400 may be connected to the base part 115 so as to penetrate therethrough, and may be located at the center of the base part 115 in the present invention, but the present invention is not limited thereto, and may be variously modified within the technical idea of being able to supply the gas G to the first body part 110 from the outside.
The injection part 400 of one embodiment of the present invention may be formed of a check valve. Referring to fig. 1 and 2, an injection flow path (not provided with a reference numeral) may be formed in the injection part 400 according to an embodiment of the present invention to communicate with an external device (not shown) connected to the injection part 400, and the gas G may flow into the container part 100 through the injection flow path.
The operation principle and effects of the injection device 1 according to the embodiment of the present invention as described above will be described.
Referring to fig. 1 and 2, an injection apparatus 1 according to an embodiment of the present invention may include a receiving portion 100, a nozzle portion 200, a valve portion 300, and an injection portion 400.
Referring to fig. 1, the receiving portion 100 may include a first body portion 110, a second body portion 130, and a movable portion 150, and the first body portion 110 may include a first body 111 and a base portion 115. The first body 111 and the second body 130 are hollow and can share a longitudinal center axis.
In one embodiment of the present invention, a distance from the lengthwise central axes of the first and second main bodies 111 and 130 to the outer surface of the second main body 130 may be formed to be relatively smaller than a distance from the lengthwise central axes to the inner surface of the first main body 111.
Therefore, the gas G can be contained in the space formed between the outer surface of the second body 130 and the inner surface of the first body 111, and the first body 111 overlaps the second body 130, so that more gas G is contained, and the pressure can be stably applied to the movable portion 150 movably disposed inside the second body 130.
Referring to fig. 1, the gas G may be supplied to the inside of the first body part 110 by an external device (not shown) or the like through the injection part 400 mounted to the first body part 110, specifically, the base part 115.
Since the gas G is supplied to the housing portion 100, pressure is applied to the movable portion 150 disposed inside the second body portion 130, specifically, the pressure may be applied in a direction toward the nozzle portion 200 (an upper direction with reference to fig. 1).
Referring to fig. 1, in the housing unit 100 according to the embodiment of the present invention, the gas G is contained in a first region formed between the outer surface of the second body 130 and the inner surface of the first body 111, and a second region communicated with the first region and formed below the movable portion 150 in the second body 130, so that the gas G pushes (pushes) the movable portion 150 toward the nozzle portion 200 (upward direction with reference to fig. 2).
Therefore, in the second body 130, the third region formed above the movable portion 150 can be kept filled with the content F, and if the valve portion 300 opens the flow path 201 formed in the nozzle portion 200, the movable portion 150 moves in the nozzle portion 200 side direction (upper direction with reference to fig. 2) by the gas G pressure applied to the movable portion 150, and the content F can be rapidly ejected to the outside.
In the process of ejecting the content F contained in the third region inside the second body portion 130 to the outside, the entire volume of the third region is reduced by the pressure continuously applied to the movable portion 150, but the state of being filled with the content F can be maintained.
Referring to fig. 2, since the pressure of the gas G contained in the first region formed between the inner surface of the first body 111 and the outer surface of the second body 130 and the second region formed below the movable portion 150 in the inner region of the second body 130 maintains the full state in the third region formed above the movable portion 150 in the inner region of the second body 130, there is an effect that the user can rapidly spray the content F to a desired position regardless of the gravity if the flow path 201 formed in the nozzle portion 200 is opened by the valve portion 300 regardless of the angle at which the user holds the spraying device 1 according to the embodiment of the present invention.
Next, the constitution, operation principle and effect of the injection device according to another embodiment of the present invention will be described.

Referring to fig. 3 to 6, the injection apparatus 2 according to another embodiment of the present invention may include a receiving portion 100, a nozzle portion 200, a valve portion 300, and an injection portion 400.
Referring to fig. 3 to 6, a base 116 according to another embodiment of the present invention is connected to the first body 111 and may be connected to a lower end of the first body 111. A predetermined region of the base portion 116 may be insertedly coupled to the first body 111.
However, the inner diameter of the base 116 may be larger than the outer diameter of the first body 111, and the first body 111 may be inserted into the base 116 in various modifications.
Referring to fig. 3 to 5, a sealing member S may be disposed between one surface of the base portion 116 and one surface of the first body 111 facing each other. The sealing member S may be formed of an elastically deformable material, and may be respectively attached to the base portion 116 and the first body 111 in an interference fit manner during the insertion of the base portion 116 into the first body 111.
Therefore, there is an effect that the gas G supplied from the outside to the inside of the first main body portion 110 can be prevented from flowing out to the outside through the space formed between the first main body 111 and the base portion 116, so that the inside of the first main body portion 110, specifically, a state in which the gas G contained inside the first main body 111 pressurizes the movable portion 150 in a preset direction (upper side with reference to fig. 3) can be maintained.
Referring to fig. 3 to 6, the sealing member S may be disposed between the first body 111 and the base 116 facing each other in a closely contact manner, and may be formed to extend circumferentially with respect to a longitudinal center axis of the first body 110.
Referring to fig. 4, the base portion 116 may have a groove portion formed in a groove shape along the circumference of the outer circumferential surface with reference to the center, in which the sealing member S can be seated. Therefore, the sealing member S can be easily attached to the base portion 116, and the base portion 116 on which the sealing member S is mounted can be inserted into the first body 111 to be stably fixed in position.
If referring to fig. 3, the first body 111 and the base portion 116 may be coupled in a hooking manner. However, the present invention is not limited to this, and various modifications are possible, and for example, bonding by ultrasonic welding or the like is possible.
Referring to fig. 3 to 6, a base unit 116 according to another embodiment of the present invention may include a base main body 117, a support portion 118, and a reinforcement portion 119.

Specifically, one surface (upper surface with reference to fig. 3) of the base main body 117 may be formed to be recessed upward (with reference to fig. 3).
Referring to fig. 3, since one surface (upper surface with reference to fig. 3) of the base main body 117 is formed in a concave shape and is formed in a curved surface shape, a plurality of supporting portions 118 to be described later are disposed on the upper side (with reference to fig. 3) of the one surface, and a plurality of reinforcing portions 119 to be described later are disposed on the lower side (with reference to fig. 3) of the one surface, thereby providing an effect that rigidity can be secured so as to be able to receive the pressure of the gas G stored in the storage portion 100.
Referring to fig. 3 to 6, the support portion 118 is coupled to the base main body 117, and the support portion 118 may be formed and coupled separately from the base main body 117, or may be variously modified and implemented, for example, may be integrally formed.
Referring to fig. 4, the plurality of support portions 118 may be equiangularly disposed with respect to the center of the base main body 117. The plurality of supporting portions 118 may be arranged at the same interval from each other.
The space formed between the plurality of support portions 118 allows a first region formed between the inner surface of the first body 111 and the outer surface of the second body 130 to communicate with a second region formed below the movable portion 150 in the second body 130, thereby maintaining the pressure of the gas G applied to the movable portion 150.
Referring to fig. 3 and 4, the second body portion 130 according to another embodiment of the present invention can contact the base portion 116, specifically, can contact the supporting portion 118, and has an effect that the supporting portion 118 can contact and support the second body portion 130.
Referring to fig. 3, 5, and 6, the reinforcing portion 119 may be formed in a curved shape and coupled to another surface (lower surface with reference to fig. 3) of the base main body 117 facing the one surface (upper surface with reference to fig. 3) to which the supporting portion 118 is coupled.
The plurality of reinforcing portions 119 may be disposed at equal angles with respect to the center of the base body 117, and specifically, a plurality of supporting portions 118 may be coupled to one surface (upper surface with respect to fig. 3) of the base body 117, and the plurality of reinforcing portions 119 may be coupled to a region corresponding to a space between the plurality of supporting portions 118 on the other surface (lower surface with respect to fig. 3) of the base body 117.
Referring to fig. 3 and 5, the support portion 118 connects the side portion of the base main body 117, which is in surface contact with and coupled to the inner surface of the first main body 111, to the curved surface portion of the base main body 117, and thus has an effect of ensuring rigidity.
Referring to fig. 3 to 6, the support portion 118 connects the center portion, through which the curved surface portion of the base body 117 and the injection portion 400 are connected, to the upper side of the base body 117 (with reference to fig. 3) to secure rigidity, and the reinforcement portion 119 connects the curved surface portion and the side portion of the base body 117 to the lower side of the base body 117 (with reference to fig. 3) to secure rigidity, thereby having an effect of stably receiving the pressure of the gas G stored in the storage portion 100.
Referring to fig. 4 to 6, if the injection part 400 according to another embodiment of the present invention is connected to the first body part 110, an inflow path of the gas G supplied from the outside may be formed.
Referring to fig. 4 to 6, the injection part 400 may be penetratingly coupled to the base body 117, specifically, may be penetratingly coupled to the central part. The implant part 400 according to another embodiment of the present invention may include an implant body 410, a contact part 430.
Referring to fig. 5 and 6, the injection body 410 and the contact portion 430 may be integrally formed, and the cross-sectional area of the contact portion 430 may be formed to be relatively larger than the cross-sectional area of the injection body 410 with respect to the longitudinal central axis.
If referring to fig. 5 and 6, the outer diameter of the contact portion 430 may be formed to be relatively larger than the outer diameter of the injection body 410.
Therefore, the contact portion 430 can be attached to the base body 117 so as to cross the base body, and thus the outflow of the gas G from the housing portion 100 to the outside can be cut off.
Referring to fig. 5 and 6, an injection body 410 according to another embodiment of the present invention may be exposed to the outside of the receiving part 100 so as to be connected to an external device. The contact portion 430 is connected to the injection main body 410, and may be connected to the other side (upper side with reference to fig. 5) of the injection main body 410, which is opposite to the one side (lower side with reference to fig. 5) of the injection main body 410 that can be contacted with an external device.
Referring to fig. 5 and 6, the injection passage 411 is formed in the injection part 400, specifically, the injection body 410, and the gas G can be supplied from the outside to the inside of the housing part 100 through the injection passage 411. Referring to fig. 5 and 6, the injection passage 411 may be formed by cutting one side of the injection body 410.
Referring to fig. 5, the injection part 400 is connected to an external device, gas G is supplied through the injection flow path 411, the injection part 400 moves in an upper direction (with reference to fig. 5) due to the pressure of the supplied gas, one surface of the injection part 400, specifically, one surface of the contact part 430 (with reference to fig. 5) is spaced apart from the base body 117, and the gas G can be supplied to the receiving part 100 through a space formed between the base body 117 and the contact part 430.
Referring to fig. 6, since the injection part 400 may be formed of an elastically deformable material, if an external device for supplying the gas G is removed after the gas G is supplied, the injection part 400 is elastically deformed by the pressure of the gas G applied to the upper side of the injection part 400, specifically, the contact part 400 is elastically deformed to be closely attached to the base body 117, and the gas G is prevented from flowing out of the housing part 100.
The contact portion 430 is disposed in a contactable manner at a central portion of the base main body 117, and an outer diameter of the contact portion 430 is formed larger than an outer diameter of the injection main body 410 and an inner diameter of the central portion of the base main body 117, so that it can be laterally extended to the base main body 117.
The contact portion 430 is transversely crossed with respect to the base body 117, and thus if the gas G is supplied to the inside of the accommodating portion 100 through the injection body 410, the injection portion 400, specifically, the contact portion 430 is pressurized in a lower direction (with reference to fig. 5) by the pressure of the gas G, so that a state in which the injection portion 400 is closely adhered to the base portion 116 is maintained.
Referring to fig. 5 and 6, an injection passage 411 formed in an injection part 400, specifically, an injection body 410 according to another embodiment of the present invention may be formed in a cut shape.
Specifically, the injection passage 411 is formed in a cylindrical shape, but is not limited thereto, and may be variously modified within the technical idea of forming a passage and supplying the gas G from the outside.
Referring to fig. 5 and 6, the injection passage 411 may be formed in a groove shape on the injection main body 410 side, and one side (left side with reference to fig. 5) may be axially opened along the longitudinal direction.
Therefore, the injection passage 411 formed in the injection body 410 can be connected to the inner circumferential surface of the center portion of the base body 117 facing thereto, thereby forming a path for supplying the gas G.
The injection passage 411 formed in the injection body 410 is connected to the inner circumferential surface of the base body 117 to form a supply path of the gas G, so that the injection part 400, specifically, the contact part 430 can be pushed up by the pressure of the supplied gas G, and the gas G can flow into the housing part 100 through the space formed between the injection part 400 and the inner circumferential surface of the base body 117.
The user can put a tool such as a lever into the injection passage 411 formed in the injection body 410 and push (push) the injection unit 400, specifically, the contact unit 430, in one direction (upward direction with reference to fig. 6).
A tool such as a rod is put in and the contact portion 430 is pushed, so that the base portion 116 can be spaced apart from the contact portion 430 and the gas G contained in the containing portion 100 can be discharged.
Therefore, when the injection device 2 containing the content F in the used-up containing part 100, specifically, in the second body part 130 is discarded, the user can easily discharge the gas G to the outside by pushing the contact part 430 toward the nozzle part 200 (upward direction with reference to fig. 6) through the injection passage 411 formed in the injection body 410 by using a tool such as a lever. The configuration, operation principle, and effects of the housing portion 100, the nozzle portion 200, and the valve portion 300 of the injection device 2 according to the other embodiment of the present invention are the same as those of the housing portion 100, the nozzle portion 200, and the valve portion 300 of the injection device 1 according to the one embodiment of the present invention except for the configurations of the base portion 116 and the injection portion 400, and therefore, detailed description thereof is omitted insofar as it overlaps.
The first body and the second body of the spraying device according to the embodiment of the present invention are overlapped with each other, and the pressure applied to the movable portion disposed inside the second body is maintained, so that the contents can be sprayed quickly when the flow path formed in the nozzle portion is opened regardless of the grip angle of the user or the gravity.
The particular implementation described in this disclosure is illustrative only and is not intended to limit the scope of the invention in any way. For the sake of simplicity of the description, the description of the conventional electronic configuration, control system, software, and other functions of the system may be omitted. In addition, the line connection or the connection member between the components illustrated in the drawings exemplarily shows functional connection and/or physical or circuit connection, and may be replaced with or shown as additional connection of various functions, physical connection or circuit connection in an actual device.
