The lower ring 44 may be installed at both side ends of the frame 22 located below the sprayer 10. The upper ring 42 may be installed at the central portion of the reservoir 12 located at the top of the sprayer 10. Suspenders 40 are two pairs so that the sprayer 10 can be attached to both shoulders of the user, the upper end is installed as one upper ring 42 and the lower end is separated into both sides of the sprayer 10, respectively, the lower ring It is installed in 44, respectively.

The upper ring 42 is a bar-shaped structure that is elongated and is installed so that both ends thereof can be rotated in the reservoir 12. As shown in FIG. 1, in order to install the upper ring 42, a storage member 12 is provided with a hinge member 46 to which the upper ring 42 is fixed, and both ends of the upper ring 42 are hinged members. It is rotatably coupled to both ends at 46. Thus, the upper ring 42 may be rotated about the both ends of the hinge member 46 in the axis.

The hinge member 46 is installed in the storage container 12 in the horizontal direction. And both ends of the upper ring 42 is bent in parallel with the hinge member 46 is fitted to the both ends of the hinge member 46 is coupled. Thus, the upper ring 42 may be rotated up and down using both side ends extending in the horizontal direction of the reservoir 12 as the rotation axis.

The upper ring 42 may be formed of a material having elasticity by itself. For example, the upper ring 42 may be made of steel.

In addition, the upper ring 42 may be formed by bent toward the hinge member 46, the middle portion 48 between the both ends. This intermediate portion 48 allows the atomizer 10 to be more firmly coupled to the carrier 50. This will be explained later.

The carrier 50 is equipped with a nebulizer 10 to move the nebulizer 10 as necessary.

The carrier 50 is connected to a lower frame 52 supporting the lower end of the sprayer 10, a wheel installed at the lower frame 52, a vertical frame connected to the lower frame 52 and extending upward, and a vertical frame. Installed and detachably coupled to the sprayer 10 may include a fixing portion for fixing the sprayer 10.

The lower frame 52 and the vertical frame 54 may be disposed at right angles and connected integrally. The upper end of the vertical frame 54 may form a handle for pushing or pulling the carrier 50. Wheel 56 is rotatably coupled to one end of the lower frame 52 to which the vertical frame 54 is connected. On the opposite end of the wheel 56 of the lower frame 52, a support 57 for supporting the carrier 50 on the floor in a horizontal state may be installed to extend downward.

The lower frame 52 and the vertical frame 54 may have a size sufficient to support the lower and rear surfaces of the sprayer 10, respectively, and may be variously modified according to the size or shape of the sprayer 10.

The fixing part of the present embodiment is provided with a horizontal frame 60 installed on the vertical frame 54, a protruding bar 62 installed on the horizontal frame 60 and protruding upward to insert the upper ring 42 of the sprayer 10. It may include.

In addition, the fixing part may further include side fixing parts for fixing both sides of the sprayer (10). The side fixing part may include at least one or more side bars 64 respectively installed at both side ends of the vertical frame 54 and extending to both sides of the sprayer 10.

Thus, as shown in Figure 2, the nebulizer 10 is fixed while the upper ring 42 is fitted to the protruding bar 62 of the carrier 50, the flow in both sides by the side bar 64 This can be prevented and firmly fixed to the carrier 50.

The horizontal frame 60 is installed in a horizontal direction between both side ends of the vertical frame 54. Protruding bar 62 protrudes upward at an intermediate position of the horizontal frame 60. The protruding bar 62 is a plate-shaped structure extending upward, and is formed to have a size that can be fitted into the upper ring 42. Protruding bar 62 may be formed by bending the top or the middle portion outward. That is, the middle portion or the upper end of the protruding bar 62 may be formed to be bent to the opposite side to the side where the sprayer 10 is located with respect to the vertical frame 54. In this structure, when the upper ring 42 fitted to the protruding bar 62 is rotated upward, it is difficult to be caught from the protruding bar 62 by being caught by the bent middle portion or the upper end of the protruding bar 62. Therefore, the fixing force of the nebulizer 10 with respect to the carrier 50 can be heightened more.

The protrusion bar 62 may be installed at a position corresponding to the installation position of the upper ring 42 when the sprayer 10 is placed on the lower frame 52 of the carrier 50. Accordingly, while placing the sprayer 10 on the lower frame 52 of the carrier 50, the upper ring 42 installed on the rear surface of the reservoir 12 can be rotated to be fixed to the protruding bar 62. The height of the protrusion protruding upwards may be such that the upper ring 42 is not rotated to escape the protrusion bar 62. Therefore, when the upper ring 42 is fitted to the protruding bar 62, the upper ring 42 is not separated from the protruding bar 62 even when the upper ring 42 is rotated upward.

Since the protrusion bar 62 is located at the horizontal center of the carrier 50 and the upper ring 42 is located at the middle of the reservoir 12, the protrusion bar 62 is formed at the middle portion 48 of the upper ring 42. ). In the present embodiment, the middle portion 48 of the upper ring 42 is formed to be bent toward the hinge member 46, which is fitted to the protruding bar 62 to be elastically in close contact with the protruding bar 62. The intermediate portion 48 may be formed to be curved in an arc toward the hinge member 46. The upper ring 42 is caught by the protruding bar 62 while the middle portion 48 is pressurized in close contact with the protruding bar 62. Thus, the upper ring 42 is more firmly fixed to the protruding bar 62, it is possible to effectively prevent the departure from the protruding bar 62.

The side bar 64 may be installed below the protruding bar 62 along the vertical frame 54 of the carrier 50. The spacing between the side bars 64 may correspond to the size between both side ends of the nebulizer 10 at that location when the nebulizer 10 is placed on the carrier 50. Thus, when the sprayer 10 is fixed to the carrier 50, the sidebar 64 is in close contact with the sprayer 10 side without the gap between the sidebar 64 and the sprayer 10. Therefore, it is possible to prevent the nebulizer 10 from flowing laterally and to increase the fixing force.

In addition, the fixing part may further include a lower end fixing part for fixing the lower end of the sprayer 10. The lower fixing part may include fixing protrusions 66 installed at both side ends of the lower frame 52 and protruding upwards to which the lower ring 44 of the sprayer 10 is fitted.

Accordingly, the sprayer 10 is fixed to the carrier 50 while the upper and side surfaces are fixed by the protrusion bar 62 and the side bar 64, and the lower ring 44 is fitted to the fixing protrusion 66. Can be fixed.

The fixing protrusion 66 may be installed at a position corresponding to the lower ring 44 when the sprayer 10 is placed on the lower frame 52 of the carrier 50. Thus, when the frame 22 of the sprayer is placed on the carrier lower frame 52, the fixing protrusion 66 is inserted through the lower ring 44 of the frame. The protruding height of the fixing protrusion 66 may be such that the upper end of the fixing protrusion protrudes upward through the lower ring 44 when the sprayer is completely placed on the lower frame. Thus, when the lower ring 44 is fitted to the fixing protrusion 66, the lower ring 44 is not easily separated from the fixing protrusion 66 even if the sprayer is shaken upward from the carrier.

Hereinafter, the operation of the spray apparatus according to the present embodiment will be described with reference to FIGS. 3 to 5.

If necessary, the nebulizer 10 may be coupled to the carrier 50 or used separately from the carrier 50.

As shown in FIG. 3, the sprayer 10 is mounted on the carrier 50 so that the rear surface of the sprayer 10 provided with the upper ring 42 faces the vertical frame 54 of the carrier 50.

When the sprayer 10 is in close contact with the vertical frame of the carrier 50 in a state spaced upwardly from the lower frame 52 of the carrier 50, the side bar 64 installed on the carrier 50 may have an amount of the sprayer 10. It is located on the side. The upper ring 42 installed at the rear of the sprayer 10 rotates to the outside and opens, and when the sprayer 10 is lowered as it is, the sprayer 10 is placed on the lower frame 52 and seated. And the upper ring 42 is fixed to be inserted into the protruding bar 62 while moving down, such as the sprayer (10). In this process, the lower ring 44 is fitted into and fixed to the fixing protrusion 66 formed on the lower frame.

As shown in FIGS. 4 and 5, when the sprayer 10 is completely placed on the lower frame 52 with the protruding bar 62 inserted into the upper ring 42, both sides of the carrier 50 are disposed. Bar 64 is in close contact with both sides of the sprayer 10, the upper ring 42 is fully fitted to the protrusion bar 62 is coupled. Thus, the nebulizer 10 is caught by the side bar 64 fixed to the carrier 50 so as not to flow in the horizontal direction. In addition, the upper ring 42 is fitted into the protruding bar 62 to be caught, thereby preventing the sprayer 10 from flowing forward in the carrier 50. The lower ring 44 is fitted into the fixing protrusion 66 to prevent the lower end of the sprayer from flowing in the carrier.

Sprayer 10 is placed on the lower frame 52 by its own weight, the rear surface is in close contact with the vertical frame 54, the state of movement up or back is also blocked. And as mentioned, the lower ring is fixed to the fixing projections and the upper ring is fixed to the protrusion bar and the side bar supports the side of the sprayer. Therefore, the nebulizer 10 may be firmly fixed to the carrier 50 without shaking or flowing in all directions up, down, left, right, before and after.

The upper ring 42 is installed in the reservoir 12 via the hinge member 46. When the upper ring 42 is pulled, the upper ring 42 is elastically deformed while the upper ring 42 is elastically deformed. Will be reached. Thus, when the upper ring 42 is inserted into the protrusion and released, the reservoir 12 is returned to its original state and the upper ring 42 is tightly fixed to the protrusion.

In addition, since the intermediate part 48 formed on the upper ring 42 is in contact with the protruding bar 62, the intermediate part 48 bent in an arc shape is elastically deformed while being in close contact with the protruding bar 62 to apply an elastic force. . Thus, the upper ring 42 may be more firmly fixed to the middle portion 48 is elastically pressed close to the pressing portion. Therefore, the fixing force of the sprayer 10 with respect to the carrier 50 can be increased to effectively prevent the sprayer 10 from being separated from the carrier 50 by external vibration or impact.

When the user wants to use the sprayer 10 separated from the carrier 50, the sprayer 10 can be easily detached by removing the fixing ring from the protruding bar 62. That is, in the reverse order of fixing the sprayer 10 to the carrier 50, while lifting the sprayer 10 upward from the carrier 50 while rotating the fixing ring upward, the upper ring 42 at the protruding bar 62. Is separated. Lower ring 44 is also separated from the fixing projections 66 of the lower frame. Thus, the coupling state of the carrier 50 and the nebulizer 10 is released so that the nebulizer 10 can be separated from the carrier 50.

While the exemplary embodiments of the present invention have been illustrated and described as described above, various modifications and other embodiments may be made by those skilled in the art. Such modifications and other embodiments are all considered and included in the appended claims without departing from the true spirit and scope of the invention.
